| 1 | Hyperthermic intraperitoneal chemotherapy for gastric cancer with peritoneal metastasis:A multicenter propensity scorematched cohort study显示文摘Objective:Systemic chemotherapy has limited efficacy in the treatment of peritoneal metastasis(PM)in gastric cancer(GC).Hyperthermic intraperitoneal chemotherapy(HIPEC)combined with complete cytoreductive surgery(CRS)has shown promising outcomes but remains controversial.The present study aimed to evaluate the safety and efficacy of HIPEC without CRS in GC patients with PM.Methods:This retrospective propensity score-matched multicenter cohort study included GC patients with PM treated with either chemotherapy alone(Cx group)or with HIPEC combined with chemotherapy(HIPEC-Cx group)in four Chinese high-volume gastric medical centers between 2010 and 2017.The primary outcomes were median survival time(MST)and 3-year overall survival(OS).Propensity score matching was performed to compensate for controlling potential confounding effects and selection bias.Results:Of 663 eligible patients,498 were matched.The MST in the Cx and HIPEC-Cx groups was 10.8 and 15.9 months,respectively[hazard ratio(HR)=0.71,95%confidence interval(95%CI),0.58-0.88;P=0.002].The 3-year OS rate was 10.1%(95%CI,5.4%-14.8%)and 18.4%(95%CI,12.3%-24.5%)in the Cx and HIPEC-Cx groups,respectively(P=0.017).The complication rates were comparable.The time to first flatus and length of hospital stay for patients undergoing HIPEC combined with chemotherapy was longer than that of chemotherapy alone(4.6±2.4 d vs.2.7±1.8 d,P<0.001;14.2±5.8 d vs.11.4±7.7 d,P<0.001),respectively.The median follow-up period was 33.2 months.Conclusions:Compared with standard systemic chemotherapy,HIPEC combined with chemotherapy revealed a statistically significant survival benefit for GC patients with PM,without compromising patient safety. | Ziying Lei Jiahong Wang Zhi Li Baozhong Li Jiali Luo Xuejun Wang Jin Wang MingchenBa Hongsheng Tang Qingjun He Quanxing Liao Xiansheng Yang Tianpei Guan Han Liang Shuzhong Cui | 2020 | Chinese Journal of Cancer Research2020，32，6： | 11 |
| 2 | A multi-institutional retrospective study of hyperthermic plus intravesical chemotherapy versus intravesical chemotherapy treatment alone in intermediate and high risk nonmuscle-invasive bladder cancer显示文摘Objective:To compare the efficacy and safety of hyperthermic intravesical chemotherapy(HIVEC)and intravesical chemotherapy(IVEC)in patients with intermediate and high risk nonmuscle-invasive bladder cancer(NMIBC)after transurethral resection.Methods:We included 560 patients diagnosed with primary or recurrent NMIBC between April 2009 and December 2015 at 1 of 6 tertiary centers.We matched 364 intermediate or high risk cases and divided them into 2 groups:the HIVEC+IVEC group[chemohyperthermia(CHT)composed of 3 consecutive sessions followed by intravesical instillation without hyperthermia]and the IVEC group(intravesical instillation without hyperthermia).The data were recorded in the database.The primary endpoint was 2-year recurrence-free survival(RFS)in all NMIBC patients(n=364),whereas the secondary endpoints were the assessment of radical cystectomy(RC)and 5-year overall survival(OS).Results:There was a significant difference in the 2-year RFS between the two groups in all patients(n=364;HIVEC+IVEC:82.42%vs.IVEC:74.18%,P=0.038).Compared with the IVEC group,the HIVEC+IVEC group had a lower incidence of RC(P=0.0274).However,the 5-year OS was the same between the 2 groups(P=0.1434).Adverse events(AEs)occurred in 32.7%of all patients,but none of the events was serious(grades 3–4).No difference in the incidence or severity of AEs between each treatment modality was observed.Conclusions:This retrospective study showed that HIVEC+IVEC had a higher 2-year RFS and a lower incidence of RC than IVEC therapy in intermediate and high risk NMIBC patients.Both treatments were well-tolerated in a similar manner. | Qiang Ruan Degang Ding Bin Wang Chaohong He Xuequn Ren Zhenhua Feng Zhigang Pang Jin Wang Xiangliang Zhang Hongsheng Tang Jiahong Wang Qingjun He Ziying Lei Quanxing Liao Jiali Luo Shuzhong Cui | 2021 | Cancer Biology & Medicine2021，18，1： | 4 |
| 3 | Body Size but Not Food Size Determined Head Sexual Dimorphism in Rana kukunoris from the Tibetan Plateau显示文摘Sexual dimorphism between males and females is a common pattern observed in the natural world and has become one of the main focuses of evolutionary biology.Amphibian head size and shape are important factors that may influence food acquisition,but knowledge about the sexual differences between amphibian head size and shape is relatively scant.Here,intersexual differences in the head size and shape of Rana kukunoris,which is a high-elevation frog from the Qinghai-Tibet Plateau,were investigated.Significant differences were found in the head shape but not the head size between sexes.A significant correlation was also observed between prey size and head size.However,these correlations disappeared when individual body size was controlled,suggesting that body size but not food size was the main factor resulting in intersexual differences in head size/shape.The results suggested that food competition between sexes did not result in sexual dimorphism of head shape among these frogs. | Hongzhou CHEN Haifen QIN Zhenkun ZHAO Jiahong LIAO Yanfang WU Xueyan LIU Lichun JIANG Buddhi DAYANANDA Wei CHEN | 2023 | Asian Herpetological Research2023，14，2： | 1 |
| 4 | No Male Preference for Large Females in the Asian Common Toad(Duttaphrynus melanostictus):Effect of the Sex Ratio and Breeding System显示文摘Mating preferences are common in natural populations of animals.Numerous studies have shown that male mate choice can occur in a wide range of taxa.However,male mating preferences are still poorly understood in anurans.Sexual selection theory predicts that male mate choice is not expected to arise if 1) adult population exhibited a highly male-biased sex ratio which will diminish male mating success;2) males provide less parental care;3) mating success of males is associated with chorus tenure in which males would maximize their fitness by mating with multiple mates.We tested these predictions in the Asian common toad Duttaphrynus melanostictus from southeastern Tibet,China.Our field experimental results indicated that,the breeding population exhibited a highly male-biased sex ratio,called males did not defend sites which contain significant resources required by females and offspring,both sexes provided no parental care after egg-laying,and the toad species was characterized with prolonged breeding season chorus attendance.In male mate choice experiment,males did not show preferences for a larger gravid female over a smaller gravid female.We suggest that male mating success in the Asian common toad is likely determined by the number but not the quality of mates.Future research should focus on how sexual selection on male acoustic signaling and how female preference exert different types of selection pressure on male call traits in this Tibet toad. | Lixia ZHANG Xiangyu YUAN Yongsun SHENG Xueting ZHONG Jiahong LIAO Zhenhao LIU Wei CHEN | 2020 | Asian Herpetological Research2020，11，4： | 0 |
| 5 | Broadband tunable instantaneous frequency measurement system based on stimulated Brillouin scattering显示文摘A broadband tunable instantaneous frequency measurement(IFM)system is designed based on the stimulated Brillouin scattering effect of the highly nonlinear fiber in which the carrier suppressed single sideband modulated signal of the Brillouin frequency shift acts as pump light.The amplitude comparison function(ACF)is constructed by the power radio of the two paths in the system.The frequency measurement range and measurement accuracy can be tuned by changing the frequency difference of the two phase modulation signals.The tunable frequency measurement ranges of 2—5 GHz,2—10 GHz,2—15 GHz,2—20 GHz,and 2—24 GHz are realized,and the corresponding measurement accuracies are 3.64 d B/GHz,2.17 d B/GHz,1.87 d B/GHz,1.22 d B/GHz,and 0.77 d B/GHz,respectively. | LIAO Weijie ZHANG Jiahong CAI Qibin | 2023 | Optoelectronics Letters2023，19，3： | 0 |
