| 1 | Interactions of Copper, Evaporite, and Organic Matter and Genesis of Sandstone-Hosted Copper Deposits in the Chuxiong Basin, Yunnan Province显示文摘Studies on organic geochemistry indicate that the origin, type and maturity of organic matter are different among coal-bearing, copper-bearing and evaporite formations in the Mesozoic continental Chuxiong Basin, Yunnan, China. A mechanism has been proposed that (1) during the diagenetic mineralization stage the short-chain organic acids dervied from kerogen played an important role in remobilizing copper from source beds, while oils acted as important carrier of copper, and that (2) during the transformation or remolding mineralization stage, meteoric water leached the evaporite layers and formed downward-percolating oxidizing SO42-rich fluids; meanwhile, the copper-bearing fluids migrating upwards along growth faults from the basement was contaminated by the coal-bearing series on the way and formed reducing organic-rich fluids; oxidation-reduction occurred and sulfides formed when the two kinds of fluids met within sandstones. | Zhuang Hanping, Institute of Geochemistry, Chinese Academy of Sciences, Guiyang, GuizhouRan Chongying, He Mingqin, Geology Department, Kunming Institute of Technology, Kunming, Yunnanand Lu Jialan Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangdong | 1996 | Acta Geologica Sinica(English Edition)1996，70，4： | 5 |
| 2 | Organic/ Inorganic Occurrence of Metallic Elements of the Black Shale-Hosted Baiguoyuan Silver-Vanadium Deposit in Xingshan, Hubei显示文摘By means of kerogen purification, the proton induced X-ray emission (PIXE) and instrumental neutron activation analysis (INAA), the authors have studied the organic/inorganic occurrence modes of the metallic elements of the Baiguoyuan silver-vanadium deposit hosted in black shale in Hubei Province, China. The result shows that Au, Hg and Ta have a strong tendency to occur organically, with more than 70% of these elements being associated organically. Se, Ga, Ag and Hf are partly associated with organic matter, with more than 20% of them occurring organically. Compared with the above elements, Zn, Cu, As and Sb are weakly associated organically, and tend to be enriched in kerogen. However, Mn, Th, U, V, Co, Cr, Al, Fe and Sc usually occur inorganically. Of the rare earth elements (REE), La, Ce, Tb, Dy, Yb and Lu have stronger ability to be associated with organic matter than Sm and Eu. | ZHUANG Hanping LU Jialan FU Jiamo LIU Jinzhong REN Chigang ZOU Degang TIAN Weizhi | 1998 | Acta Geologica Sinica(English Edition)1998，72，3： | 4 |

| 10 | Evidence for transforming mineralization of Baiguoyuan silver-vanadium deposit hosted in black shale in Hubei,China显示文摘Baiguoyuan silver-vanadium deposit is generally thought to be of sedimentary-diagenetic origin. Based on the characteristics of barites, it is suggested that hydrothermal transformation has been involved in mineralization. The barites in black shale can be grouped into irregular ones which were formed during early diagenesis and tabular ones which were formed during late diagenesis. The tabular barites are replaced by pyrite and have formed a regular girdle around them. PIXE analysis states that Ag is greatly concentrated in pyrite replacement girdle. The girdle is the product of hydrothermal transformation. The transformation is one of the main mineralization stages of Baiguoyuan deposit. | Hanping Zhuang Jialan Lu Jiamo Fu Jinzhong Liu Chigang Ren Degang Zou | 1999 | Chinese Science Bulletin1999，44，3： | 1 |

| 15 | Two kinds of Carlin-type gold deposite in southwestern Guizhou,China显示文摘Based on the organic geochemical studies on two typical Carlin-type deposits in southwestern Guizhou, as well as the comparison between the two deposits in terms of geological background,igneous rock, paleo-oilfield, lithofacies and paleogeographical and geochemical features, two kinds of Carlin-type deposit were proposed: Lannigou Type and Getang Type. The former includes Lannigou,Banqi and Yata gold deposits. These deposits are hosted by turbidite, geographically situated in the southwest of the mineralized district, and related genetically to paleo-oilfields. The latter includes Getang, Zimudang and Dachang gold (mercury and thallium) deposits, situated geographically in the northwest of the mineralized district where Emeishan basalt commonly occurs. These deposits are associated with reduction of coaly organic matter. | Hanping Zhuang Jialan Lu Jiamo Fu Dehan Liu | 1999 | Chinese Science Bulletin1999，44，2： | 0 |
| 16 | Pial iontophoresis of ferric chloride versus cortical ferric chloride injection in establishing iron-induced posttraumatic epilepsy animal models显示文摘BACKGROUND: In order to study the pathogenesis of iron-induced posttraumatic epilepsy (PTE), foreign scholars have established several kinds of PTE animal models, among which, the iron- induced PTE animal models proposed by Willmore is the most famous. The iron-induced PTE animal models can be established by two methods: one is cortical ferric chloride injection (CFCI) and the other one is pial iontophoresis of ferric chloride (PIFC). Because Willmore did not give out the elaboration of the behaviors and electroencephalograms (EEGs) of the iron induced PTE animal models established by these two methods, so we have known little about these animal models. OBJECTIVE: To observe the behaviors and EEGs of the iron-induced PTE animal models established by PIFC and CFCI, in order to compare the differences and the study value of these two methods.DESIGN: Qualitative controlled observation trial.SETTING: Department of Neurosurgery, Urumqi General Hospital, Lanzhou Military Area Command of Chinese PLA.MATERIALS: Forty healthy adult male SD rats, weighing 200 to 250 g, were involved in this experiment. Reagents and instruments: Ferric chloride (FeCl3·6H2O, Sigma USA), rat stereotaxic apparatus (ASI company, USA), the wireless blue tooth electroencephlograms recording system (Nuocheng electric Co.Ltd, Shanghai), a set of air turbine dental drill unit, dental base acrylic resin powder, microinjector (50 μL), amperemeter (1 mA), a pair of batteries, electric resistance (200 kΩ) , variable resistance (100 kΩ), tubule with endo-meridians of 2 mm (used as import tube), several silver wire segments and several acupuncture needles were employed in this study.METHODS: This study was carried out in the Experimental Animal Center of the Urumqi General Hospital, Lanzhou Military Area Command of Chinese PLA between November 2004 and April 2005. Establishing the PET animal models by CFCI method: Twenty SD rats were taken, intraperitoneally anesthetized with 50 mg/kg barbanylum and fixed on stereotaxic apparatus. A cranial burr hole with the diameter of 2 mm was drilled 3 mm behind the coronal suture and 2 mm lateral to the sagittal line on the left cranium. Another 5 cranial burr holes with diameter of 2 mm were drilled to place electrodes. The positions of holes were set that taking bregma as original point, sagittal line as Y-axis, the line through the original point and vertical to the Y-axis as X-axis. The unit of the coordinate axis was mm. The coordinate value of the electrodes were (4, 0), (4, -6), (-4, 0), (-4, -6), at last, a hole with the diameter of 2 mm was drilled on the center of the coronale. 5 μL ferric chloride solution (FeCl3, 100 mmol/L, pH 1.5) was injected into the sensorimotor cortex of rats using microinjector within 5 minutes. The needling depth was 3 mm. The needle was retained for 5 minutes so as to prevent the outflow of liquid. Establishing the PTE animal models by PIFC method: Twenty SD rats were chosen and weighed, and the procedures after weighing were as above.A cranial burr hole with the diameter of 4 mm was drilled in the position where needle inserted in animal models established by CFCI method. Cerebral dura mater was cut. Another 5 holes were drilled to place electrodes in the same position as above. The tip of tubule cotton stuffed inside (to prevent the rapid flow of FeCl3 solution, 100 mmol/L, pH 1.5) was gently connected to cerebral pia mater. The positive and negative electrodes of the amperemeter whose output current was 100 μA were connected to acupuncture needles. The acupuncture needle, which was connected to positive electrode, was inserted into ferric chloride solution, and that which was connected to negative electrode was inserted into the right forelimb of rats subcutaneously. The rats were galvanized for 10 minutes. Record of EEG: The silver wire with blunt anterior extremity was placed on the cerebral dura mater. Then, silver wire and cranial bones were firmly fixed with dental base acrylic resin power. The other side was connected to the wireless blue tooth electroencephlograms recording system to monitor EEG changes. Assessment criteria of seizure degree: Grade Ⅰ: 'wet dog-like' shudder, facial muscle convulsion and chewing;Grade Ⅱ: rhythmical nodding;Grade Ⅲ: forelimb clonus;Grade Ⅳ: forelimb clonus while standing: Grade Ⅴ: lost the balance, vert, limb’s convulsion and the whole body’s tic. MAIN OUTCOME MEASURES: Behaviors and EEGs changes of iron-induced PTE animal models established by PTFC and CFCI. RESULTS: All the 40 rats were involved in the result analysis. ① The changes of the behaviors: The two animal models both had the epileptic seizures. The epileptic seizure of the animal model established by PIFC mainly presented automatic behavior of chewing, and facial muscle convulsion accompanied with chewing. Epileptic seizure reached the peak within 2.5 to 7 hours after model establishing.It was gradually decreased within 24 hours and hardly seen 1 day after model establishing. The epileptic seizure of the rat model established by CFCI mainly presented turnover upspring and limbs’ convulsion and urinary incontinence accompanied. The epileptic seizure reached the peak within 3 to 8 hours.It was relatively frequent within 1 week and gradually decreased within 2 weeks after model establishing. The PTE animal models established by CFCI were more closed to clinical PTE process. ② The form of seizures: The epileptic seizures of the rat model established by PIFC mainly presented grade Ⅰ, seldom presented grades Ⅲ, Ⅳ and Ⅴ; The epileptic seizures of rat model established by CFCI mainly presented the head turning to the right, body’s rotation, then appeared as grades Ⅳ andⅤ, and the whole procedure lasted 1 minute. At the interval of big seizures, gradeⅠwas observed. From the respect of seizure manifestation, the PTE models established by CFCI were more similar to human PTE. ③ EEGs changes: The sharp waves with average frequency of 9.66 Hz and average amplitude of 183.90 μV were observed on the EEGs of the model established by PIFC when the rats were suffering seizures. The spike waves with average frequency of 16.01 Hz and average amplitude of 143.60 μV were observed on the EEGs of the model established by CFCI when the rats were suffering seizures.CONCLUSION: ①Iron-induced PTE rat model is stable and credible. ②Compared with PTE animal model established by PIFC, PTE animal model established by CFCI is a chronic animal model, and its seizure manifestation is more similar to human PTE, so it is worth further studies. | Jinlan Jin Hanping Zhuang Shaoming Liu Junqiang Si Ying Chen Jiamei Yao | 2006 | Neural Regeneration Research2006，1，4： | 0 |
