| 1 | Cardiac autonomic neuropathy in patients with diabetes mellitus显示文摘Cardiac autonomic neuropathy(CAN)is an often overlooked and common complication of diabetes mellitus.CAN is associated with increased cardiovascular morbidity and mortality.The pathogenesis of CAN is complex and involves a cascade of pathways activated by hyperglycaemia resulting in neuronal ischaemia and cellular death.In addition,autoimmune and genetic factors are involved in the development of CAN.CAN might be subclinical for several years until the patient develops resting tachycardia,exercise intolerance,postural hypotension,cardiac dysfunction and diabetic cardiomyopathy.During its sub-clinical phase,heart rate variability that is influenced by the balance between parasympathetic and sympathetic tones can help in detecting CAN before the disease is symptomatic.Newer imaging techniques(such as scintigraphy)have allowed earlier detection of CAN in the pre-clinical phase and allowed better assessment of the sympathetic nervous system.One of the main difficulties in CAN research is the lack of a universally accepted definition of CAN;however,the Toronto Consensus Panel on Diabetic Neuropathy has recently issued guidance for the diagnosis and staging of CAN,and also proposed screening for CAN in patients with diabetes mellitus.A major challenge,however,is the lack of specific treatment to slow the progression or prevent the development of CAN.Lifestyle changes,improved metabolic control might prevent or slow the progression of CAN.Reversal will require combination of these treatments with new targeted therapeutic approaches.The aim of this article is to review the latest evidence regarding the epidemiology,pathogenesis,manifestations,diagnosis and treatment for CAN. | Gerasimos Dimitropoulos Abd A Tahrani Martin J Stevens | 2014 | World Journal of Diabetes2014，5，1： | 48 |
| 2 | Rubber band ligation for 750 cases of symptomatic hemorrhoids out of 2200 cases显示文摘AIM: To study the results for the treatment of symptomatic hemorrhoids using rubber band ligation (RBL) method. METHODS: A retrospective study for 750 patients who came to the colorectal unit from June, 1998 to September, 2006, data was retrieved from archived fi les. RBL was performed using the Mc Gown applicator on an outpatient basis. The patients were asked to return to out-patient clinic for follow up at 2 wk, 1 mo, 6 mo and through telephone call every 6 mo for 2 years). RESULTS: After RBL, 696 patients (92.8%) were cured with no difference in outcome for second or third degree hemorrhoids (P = 0.31). Symptomatic recurrence was detected in 11.04% after 2 years. A total of 52 patients (6.93%) had 77 complications from RBL which required no hospitalization. Complications were pain, rectal bleeding and vaso-vagal symptoms(4.13%, 4.13% and 1.33% of patients, respectively). At 1 mo there were a significant improvement in mean SF-36 scores over baseline in five items, while after 2 years there were improvement in all items over baseline, but not significant. No significant manometeric changes after band ligation. CONCLUSION: RBL is a simple, safe and effective method for treating symptomatic second and third degree hemorrhoids as an out patient procedure with signifi cant improvement in quality of life. RBL doesn't alter ano-rectal functions. | Ayman M El Nakeeb Amir A Fikry Waleed H Omar Elyamani M Fouda Tito A El Metwally Hosam E Ghazy Sabry A Badr Mohmed Y Abu Elkhar Salih M Elawady Hisham H Abd Elmoniam Waiel W Khafagy Mosaad M Morshed Ramadan E El Lithy Mohamed E Farid | 2008 | World Journal of Gastroenterology2008，14，42： | 24 |
| 3 | Trends and outcomes of pancreaticoduodenectomy for periampullary tumors: A 25-year single-center study of 1000 consecutive cases显示文摘AIM To evaluate the evolution, trends in surgical approaches a n d r e c o n s t r u c t i o n t e c h n i q u e s, a n d i m p o r t a n t lessons learned from performing 1000 consecutive pancreaticoduodenectomies(PDs) for periampullary tumors.METHODS This is a retrospective review of the data of all patients who underwent PD for periampullary tumor during the period from January 1993 to April 2017. The data were categorized into three periods, including early period(1993-2002), middle period(2003-2012), and late period(2013-2017).RESULTS The frequency showed PD was increasingly performed after the year 2000. With time, elderly, cirrhotic and obese patients, as well as patients with uncinate process carcinoma and borderline tumor were increasingly selected for PD. The median operative time and postoperative hospital stay decreased significantly over the periods. Hospital mortality declined significantly, from 6.6% to 3.1%. Postoperative complications significantly decreased, from 40% to 27.9%. There was significant decrease in postoperative pancreatic fistula in the second 10 years, from 15% to 12.7%. There was a significant improvement in median survival and overall survival among the periods.CONCLUSION Surgical results of PD significantly improved, with mortality rate nearly reaching 3%. Pancreatic reconstruction following PD is still debatable. The survival rate was also improved but the rate of recurrence is still high, at 36.9%. | ayman el nakeeb waleed askar ehab atef ehab el hanafy ahmad m sultan tarek salah ahmed shehta mohamed el sorogy emad hamdy mohamed el hemly ahmed a el-geidi tharwat kandil mohamed el shobari talaat abd allah amgad fouad mostafa abu zeid ahmed abu el eneen nabil gad el-hak gamal el ebidy omar fathy ahmed sultan mohamed abdel wahab | 2017 | World Journal of Gastroenterology2017，23，38： | 15 |
| 4 | Differential control of growth,apoptotic activity and gene expression in human colon cancer cells by extracts derived from medicinal herbs,Rhazya stricta and Zingiber officinale and their combination显示文摘AIM:To investigate the effects of extracts from Rhazya stricta(R.stricta) and Zingiber officinale(Z.officinale) on human colorectal cancer cells.METHODS:Human colorectal cancer cells(HCT116) were subjected to increasing doses of crude alkaloid extracts from R.stricta(CAERS) and crude flavonoid extracts from Z.officinale(CFEZO).Cells were then harvested after 24,48 or 72 h and cell viability was examined by trypan blue exclusion dye test; clonogenicity and soft agar colony-forming assays were also carried out.Nuclear stain(Hoechst 33342),acridine orange/ethidium bromide double staining,agarose gel electrophoresis and comet assays were performed to assess pro-apoptotic potentiality of the extracts.Quantitative reverse transcription-polymerase chain reaction(qRT-PCR),using gene-specific primers and Western blot analyses were performed to assess the impact of CAERS and CFEZO on the expression levels of key regulatory proteins in HCT116 cells.RESULTS:Treatment with a combination of CAERS and CFEZO synergistically suppressed the proliferation,colony formation and anchorage-independent growth of HCT116 cells.Calculated IC50,after 24,48 and 72 h,were 70,90 and 130 μg/mL for CAERS,65,85 and 120 μg/mL for CFEZO and 20,25 and 45 μg/mL for both agents,respectively.CAERS- and CFEZO-treated cells exhibited morphologic and biochemical features of apoptotic cell death.The induction of apoptosis was associated with the release of mitochondrial cytochrome c,an increase in the Bax/Bcl-2 ratio,activation of caspases 3 and 9 and cleavage of poly ADP-ribose polymerase.CAERS and CFEZO treatments downregulated expression levels of anti-apoptotic proteins including Bcl-2,Bcl-X,Mcl-1,survivin and XIAP,and upregulated expression levels of proapoptotic proteins such as Bad and Noxa.CAERS and CFEZO treatments elevated expression levels of the oncosuppressor proteins,p53,p21 and p27,and reduced levels of the oncoproteins,cyclin D1,cyclin/cyclin-dependent kinase-4 and c-Myc.CONCLUSION:These data suggest that a combination of CAERS and CFEZO is a promising treatment for the prevention of colon cancer. | Ayman I Elkady Rania Abd El Hamid Hussein Osama A Abu-Zinadah | 2014 | World Journal of Gastroenterology2014，20，41： | 12 |

| 8 | Role of relevant immune-modulators and cytokines in hepatocellular carcinoma and premalignant hepatic lesions显示文摘AIM To assess the levels of different immune modulators in patients with hepatocellular carcinoma(HCC),in relation to other hepatic diseases.METHODS Eighty-eight patients were included in the current study and represented patients with HCC(20),liver cirrhosis(28) and chronic hepatitis(CH;25),and normal controls(NC;15).Peripheral blood was isolated for immunophenotyping of active myeloid dendritic cells(m DCs;CD1 c and CD40),mature inactive myeloid cells(CD1 c and HLA),active plasmacytoid cells(p DCs;CD303 and CD40),mature inactive p DCs(CD30 and HLA),active natural killer(NK) cells(CD56 and CD161),active NK cells(CD56 and CD314) and inactive NK cells(CD56 and CD158) was done by flow cytometry.Serum levels of interleukin(IL)-2,IL-10,IL-12,IL-1β,interferon(IFN)-α,IFN-γ and tumor necrosis factor(TNF)-αR2 were assessed by ELISA.RESULTS Active m DCs(CD1 C+/CD40+) and inactive m DCs(CD1 c+/HLA+) were significantly decreased in HCC patients in relation to NC(P < 0.001).CD40+ expression on active p DCs was decreased in HCC patients(P < 0.001),and its level was not significantly changed among other groups.Inactive p DCs(CD303+/HLA+),inactive NKs(CD56+/CD158+) and active NKs(CD56+/CD161+) were not statistically changed among the four groups studied;however,the latter was increased in CH(P < 0.05).NKG2 D was statistically decreased in HCC,CH and cirrhosis(P < 0.001),and it was not expressed in 63%(12/20) of HCC patients.There was significant decrease of IL-2,IFN-α and IFN-γ(P < 0.001),and a significant increase in IL-10,IL-1β,and TNF-αR2(P <0.01,P < 0.001 and P < 0.001;respectively) in HCC patients.There was inverted correlation between IL-12 and IL-1β in HCC(r =-0.565,P < 0.01),with a strong correlation between p DCs(CD303+/CD40+) and NKs(CD56+/CD161+;r = 0.512,P < 0.05) as well as inactive m DCs(CD1 c+/HLA+) and inactive NK cells(CD56+/CD158+;r = 0.945,P < 0.001).CONCLUSION NKG2 D,CD40,IL-2 and IL-10 are important modulators in the development and progression of HCC. | Abdel-Rahman N Zekri Somaya El Deeb Abeer A Bahnassy Abeer M Badr Mona S Abdellateif Gamal Esmat Hosny Salama Marwa Mohanad Ahmed Esam El-dien Shimaa Rabah Assmaa Abd Elkader | 2018 | World Journal of Gastroenterology2018，24，11： | 6 |
| 9 | Resveratrol and fenofibrate ameliorate fructose-induced nonalcoholic steatohepatitis by modulation of genes expression显示文摘AIM: To evaluate the effect of resveratrol, alone and in combination with fenofibrate, on fructose-induced metabolic genes abnormalities in rats. METHODS: Giving a fructose-enriched diet(FED) to rats for 12 wk was used as a model for inducing hepatic dyslipidemia and insulin resistance. Adult male albino rats(150-200 g) were divided into a control group and a FED group which was subdivided into 4 groups, a control FED, fenofibrate(FENO)(100 mg/kg), resveratrol(RES)(70 mg/kg) and combined treatment( FENO + RES)( half the doses). A l l treatments were given orally from the 9th week till the end of experimental period. Body weight, oral glucose tolerance test(OGTT), liver index, glucose, insulin, insulin resistance(HOMA), serum and liver triglycerides(TGs), oxidative stress(liver MDA, GSH and SOD),serum AST, ALT, AST/ALT ratio and tumor necrosis factor-α(TNF-α) were measured. Additionally, hepatic gene expression of suppressor of cytokine signaling-3(SOCS-3), sterol regulatory element binding protein-1c(SREBP-1c), fatty acid synthase(FAS), malonyl Co A decarboxylase(MCD), transforming growth factor-β1(TGF-β1) and adipose tissue genes expression of leptin and adiponectin were investigated. Liver sections were taken for histopathological examination and steatosis area were determined.RESULTS: Rats fed FED showed damaged liver, impairment of glucose tolerance, insulin resistance, ox ida t ive s t re s s a nd dy s l ipide m ia. As fo r ge ne expression, there was a change in favor of dyslipidemia and nonalcoholic steatohepatitis(NASH) development. All treatment regimens showed some benefit in reversing the described deviations. Fructose caused deterioration in hepatic gene expression of SOCS-3, SREBP-1c, FAS, MDA and TGF-β1 and in adipose tissue gene expression of leptin and adiponectin. Fructose showed also an increase in body weight, insulin resistance(OGTT, HOMA), serum and liver TGs, hepatic MDA, serum AST, AST/ALT ratio and TNF-α compared to control. All treatments improved SOCS-3, FAS, MCD, TGF-β1 and leptin genes expression while only RES and FENO + RES groups showed an improvement in SREBP-1c expression. Adiponectin gene expression was improved only by RES. A decrease in body weight, HOMA, liver TGs, AST/ALT ratio and TNF-α were observed in all treatment groups. Liver index was increased in FENO and FENO + RES groups. Serum TGs was improved only by FENO treatment. Liver MDA was improved by RES and FENO + RES treatments. FENO + RES group showed an increase in liver GSH content.CONCLUSION: When resveratrol was given with half the dose of fenofibrate it improved NASH-related fructose-induced disturbances in gene expression similar to a full dose of fenofibrate. | Enas A Abd El-Haleim Ashraf K Bahgat Samira Saleh | 2016 | World Journal of Gastroenterology2016，22，10： | 5 |

| 11 | Drainage vs. non-drainage after cholecystectomy for acute cholecystitis:a retrospective study显示文摘Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence,this study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis.A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital,Abha,Saudi Arabia,was conducted from April 2010 to April 2012.Data were extracted from hospital case files.Preoperative data included clinical presentation,routine investigations and liver function tests.Operative data included excessive adhesions,bleeding,bile leak,and drain insertion.Complicated cases such as pericholecystic collections,mucocele and empyema were also reported.Patients who needed therapeutic drainage were excluded.Postoperative data included hospital stay,volume of drained fluid,time of drain removal,and drain site problems.The study included 103 patients allocated into two groups;group A(n = 38) for patients with operative drain insertion and group B(n = 65) for patients without drain insertion.The number of patients with preoperative diagnosis of acute non-complicated cholecystitis was significantly greater in group B(80%) than group A(36.8%)(P < 0.001).Operative time was significantly longer in group A.All patients who were converted from laparoscopic to open cholecystectomy were in group A.Multivariate analysis revealed that hospital stay was significantly(P < 0.001) longer in patients with preoperative complications.There was no added benefit for prophylactic drain insertion after cholecystectomy for acute calculous cholecystitis in non-complicated or in complicated cases. | Mohammed A Bawahab Walid M Abd El Maksoud Saeed A Alsareii Fahad S Al Amri Hala F Ali Abdul Rahman Nimeri Abdul Rahman M Al Amri Adel A Assiri Mohammed I Abdul Aziz | 2014 | The Journal of Biomedical Research2014，28，3： | 3 |
| 12 | Interaction of insulin with prokinetic drugs in STZ-induced diabetic mice显示文摘AIM:To study the possible interactions of metoclopramide,domperidone and erythromycin in streptozotocin-induced diabetic mice treated with insulin by various parameters.METHODS:Effects of the individual as well as combined drugs were studied in diabetic mice via estimation of the blood glucose and serum insulin levels,small intestinal transit(SIT),gastric emptying(GE),xylose absorption and glucose tolerance tests.Groups were given insulin 2 IU/kg s.c.,metoclopramide 20 mg/kg p.o.,domperidone 20 mg/kg p.o.and erythromycin 6 mg/kg p.o.individually and in combination.There were also normal and diabetic control groups.The first set of experiments was carried out to investigate the subchronic effect on blood glucose and serum insulin levels in diabetic mice of one week of daily dose administration of the tested drugs individually as well as the combination of insulin with each prokinetic drug.The other five sets of experiments were carried out to investigate the acute effect of a single dose of each drug individually and in combination on blood glucose and serum insulin levels,SIT,GE,oral xylose absorption and glucose tolerance tests.RESULTS:The study included the prokinetic drugs metoclopramide(20 mg/kg),domperidone(20 mg/kg) and erythromycin(6 mg/kg),as well as insulin(2 IU/kg),which was individually effective in decreasing SIT,enhancing GE and increasing xylose absorption significantly in diabetic mice.Erythromycin tended to decrease blood glucose level and increase serum insulin level after 1 wk of daily administration in diabetic mice.Erythromycin potentiated the effect of insulin on blood glucose level and serum insulin level whereas other prokinetic agents failed to do so after repeated dose administration in diabetic mice.Metoclopramide or erythromycin in combination with insulin significantly decreased SIT,in diabetic mice,to lower levels than with insulin alone.Administration of prokinetic drugs along with insulin antagonized the action of insulin on xylose absorption.These combinations also increased the rate of glucose absorption from the gut.CONCLUSION:The present study suggests that prokinetic drugs could potentially improve glycemic control in diabetic gastroparesis by allowing a more predictable absorption of nutrients,matched to the action of exogenous insulin.The use of prokinetics,such as erythromycin,may be interesting in the clinic in decreasing the need for insulin in diabetic patients.The dose of insulin may be safely decreased with erythromycin in chronic treatments. | Mohamed A Fouad Shalaby Hekma A Abd El Latif Mostafa E El Sayed | 2013 | World Journal of Gastrointestinal Pharmacology and Therapeutics2013，4，2： | 3 |
| 13 | Effectiveness of hepatitis B virus vaccination program in Egypt:Multicenter national project显示文摘AIM:To assess the effectiveness of hepatitis B virus(HBV) vaccination program among fully vaccinated children.METHODS:A national community based crosssectional study was carried out in 6 governorates representing Egypt. A total of 3600 children aged from 9 mo to 16 years who were fully vaccinated with HBV vaccine during infancy were recruited. Face to face interviews were carried out and sera were evaluated for hepatitis B surface antigen(HBsA g),anti-HBV core antibodies(total) and quantitative detection of hepatitis B surface antibody using enzyme linked immunoassays techniques. Samples positive to HBs Ag/anti-HBV core antibodies were subjected to quantitative HBV-DNA detection by real time polymerase chain reaction with 3.8 IU/L detection limit. RESULTS:Sero-protection was detected among 2059 children(57.2%) with geometric mean titers 75.4 ± 3.6 IU/L compared to 3.1 ± 2.1 IU/L among nonseroprotected children. Multivariate logistic analysis revealed that older age and female gender were the significant predicting variables for having non seroprotective level,with adjusted odds ratio 3.3,9.1and 14.2 among children aged 5 to < 10,10 to < 15 and ≥ 15 years respectively compared to those < 5 years and 1.1 among girls compared to boys with P < 0.01. HBs Ag was positive in 0.11% and breakthrough infection was 0.36% and 0.39% depending on positivity of anti-HBc and DNA detection respectively. The prevalence of HBV infection was significantly higher among children aged ≥ 7 years(0.59%) compared to 0.07% among younger children with odds ratio equal to 8.4(95%CI:1.1-64.2) and P < 0.01.The prevalence was higher among girls(0.48%) than boys(0.29%) with P > 0.05.

| 15 | Histopathological changes in the oesophageal mucosa in Egyptian children with corrosive strictures: A single-centre vast experience显示文摘BACKGROUND The caustic ingestion continues to be a major problem worldwide especially in developing countries. The long-term complications include stricture and increased life time risk of oesophageal carcinoma. Patients suffered from corrosive induced oesophageal strictures have more than a 1000-fold risk of developing carcinoma of the oesophagus.AIM To determine the possibility of oesophageal mucosal dysplasia after prolonged dilatation in post corrosive stricture.METHODS This observational study was conducted at the Paediatric Endoscopy Unit in Cairo University Children's Hospital. It included children of both sexes older than 2 years of age who had an established diagnosis of post-corrosive oesophageal stricture and repeated endoscopic dilatation sessions for more than 6 mo. All patients were biopsied at the stricture site after 6 mo of endoscopic dilatation. A histopathological examination of an oesophageal mucosal biopsy was performed for the detection of chronic oesophagitis, inflammatory cellular infiltration and dysplasia.RESULTS The mean age of the enrolled children was 5.9 ± 2.6 years; 90% of the patients had ingested an alkaline corrosive substance(potash). The total number of endoscopic dilatation sessions were ranging from 16 to 100 with mean number of sessionswas 37.2 ± 14.9. Histopathological examination of the specimens showed that 85%of patients had evidence of chronic oesophagitis(group A) in the form of basal cell hyperplasia, hyperkeratosis and subepithelial fibrosis. Thirteen percent of the patients had evidence of reactive atypia(group B) in the form of severe neutrophilic intraepithelial inflammatory cellular infiltration, and 2 patients(2%)had mild squamous dysplasia(group C); we rebiopsied these two patients 6 mo after the initial pathological assessment, guided by chromoendoscopy by Lugol's iodine.CONCLUSION The histopathology of oesophageal mucosal biopsies in post-corrosive patients demonstrates evidence of chronic oesophagitis, intraepithelial inflammatory cellular infiltration and dysplasia. Dysplasia is one of the complications of postcorrosive oesophageal stricture. | Ayman EskANDer Carolyne Ghobrial Nabil A Mohsen Bahaa Mounir Dalia Abd EL-Kareem Sara Tarek Mortada HF El-Shabrawi | 2019 | World Journal of Gastroenterology2019，25，7： | 2 |
