Objective To investigate the protective effects of mild hypothermia on cells in the CA_1 region of the hippocampus in gerbils following global ischemia-reperfusion injury(IRI),and to explore their mechanism. Methods IRI models were established in 75 gerbils.Any changes in TUNEL positive cells and the expression of Bax and Cytochrome C were then observed in normothermic(N) ,hypothermic(H)and sham(S) groups through immu- nohistochemistry methods.Results In the H group(as compared with the N group)apoptotic cells in the CA_1 sub- field of the hippocampus significantly decreased.The expression of Bax and Cyt C at 3 h,6 h and 1 d were de- creased,and the expression fastigium was delayed.Conclusion Mild hypothermia can moderate and delay cell ap- optosis,and its mechanism might be related with reducing and delaying the expression of Bax and Cyt C released by mitochondria.

Objective To characterize the growth curve of Brucella in Bact/Alert blood culture system which may be helpful to predict the growth of Brucella strain for earlier clinical diagnosis of brucellosis.Methods The epidemiological,clinical and labo-ratory data including growth curve of Brucella were reviewed and analyzed retrospectively for 15 cases of brucellosis as con-firmed by positive serological test and brucellosis agglutination test.Results All the 15 patients had irregular fever and history of animal exposure,even though their clinical feature and signs varied greatly.The growth curve of Brucella in blood culture showed the same chracteristics in the 15 patients,including:the time to positive alarm was about 72 hours,a longer lag phase, shorter logarithmic phase,a shorter vertical axis corresponding to the logarithmic phase,and a flat stable phase.Conclusions The clinical manifestation of brucellosis is variable and non-specific.Lack of awareness of this disease makes the clinicians mis-diagnose it easily.Therefore,blood culture is critical for clarifying the etiology in febrile patients.The growth curve of bacteria during blood culture is useful for early diagnosis of brucellosis and prevention of laboratory infections.

OBJECTIVE: To determinate the catalpol contents in dried rehmannia root and Taohong Siwu Decoction containing rehmannia root with high performance liquid chromatography (HPLC). METHODS: Catalpol was separated on a YWG-C18 column using water-acetonitrile (99.4:0.6) as mobile phase and detective wavelength at 210 nm. RESULTS: The linear curve of tested catalpol concentration within the range of 0.0536-5.3600 microg/microl was ideal (n=5, r=0.999 7). The average recovery rate of the dried rehmannia root and Taohong Siwu decoction was 98.7% (RSD=0.48%) and 98.2% (RSD=1.29%) respectively. CONCLUSION: HPLC method is accurate and valuable for the quality control of Radix Rehmanniae and Taohong Siwu Decoction.

The relationship between C936T polymorphism at 3'-untranslated region of vascular endothelial growth factor (VEGF) gene and diabetic nephropathy (DN) was analysed in 194 type 2 diabetic patients. The frequencies of genotype CC and allele C were significantly higher in DN group than those in non-DN group and control group. Allele C and genotype CC of VEGF may be a genetic marker susceptible to DN.

Objective To enhance and improve the accuracy of data,security of system and user friendliness of on-line editing system processing ancient TCM books.Methods Web and java technology were applied to implement and demonstrate the key algorithm.Results In these solutions,pictures could be watermarked,on-line editing was supported,picture-naming was standardized with 7-characters,multi-user on-line editing was available,etc.The ancient TCM books on-line editing system became more practical,effective and user-friendly.Conclusion The solutions mentioned above have achieved the expected effects in digitalization research of ancient TCM books,showing its feasibility and practicability.

Library of China Academy of Traditional Chinese Medical Sciences has retained video data of the early 1980s,which were clinical experiences of the national-level experts of traditional Chinese medicine.To meet the research needs,to rescue the valuable film resources,and to expand continuing education programs,we took use of the hospital's research and LAN infrastructure,combined with multimedia technology,designed and built a “Chinese multimedia resource management platform”,in compliance with the idea of “base on Chinese medicine,focuse on clinical practice and respect for the classics.

Objective To investigate reliability and validity of the Chinese version of the schedule for assessment of insight (SAI).Methods The original version of SAI was translated into Chinese and then backtranslated into English to develop the Chinese version of SAI which reliability and validity were tested.220 subjects who met the diagnosis of Schizophrenia,schizophreniform disorder,schizoaffective disorder,delusional disorder or brief psychotic disorder were assessed.Results The Cronbach's α was 0.890 ; the test-retest reliability was 0.742 ; the inter-rater reliability was 0.986.Three main factors were obtained from the factor load matrix as awareness of illness,ability to relabel psychotic experience,compliance with treatment.The loading coefficient were 0.883-0.944.The correlation of the SAI total score and three subscales with insight of PANSS were-0.635,-0.305,-0.631 and-0.512 respectively (P ＜ 0.01).Conclusion The SAI has good reliability and validity.The scale is useful to measure insight in psychosis.

This is to report the study of degradation of earthworm extracts prepared by wet superfine grinding in simulated gastrointestinal environment. Enzymatic reactions were terminated by adjusting the solution pH or using membrane bioreactor principle. Earthworm protein concentration change was detected by Bradford method, the degraded state of protein was described with SDS-PAGE technology, and the degraded state of small molecule substances was detected by HPLC. The results showed that earthworm protein degraded completely in artificial gastric juice. High molecular weight protein degraded greatly in artificial intestinal fluid, while low molecular weight protein was not significantly degraded. Small molecular substances degradation did not degrade in artificial gastric juice, while they degraded obviously in artificial intestinal fluid, there is even new small molecule substance appeared. Finally it is concluded that the substance that having therapeutic effects in vivo may be some degraded peptide, amino acid and stable small molecules existed in artificial intestinal fluid.

Objective To study the diagnosis and treatment of hyperthyroidism companied with thyroid carcinoma . Methods The clinical data of 11 cases of hyperthyroidism with thyroid carcinoma were retrospectively analysed. Results 9 of 11 cases were diagnosed preoperatively,and comfirmed by frozen section intra-operatively and underwent suitable operation. In the other two cases the final diagnosis was made by pathological examination postoperatively, and re-operation was performed on 1 case . All the patients were followed up for 1～16 years and neither hyperthyroidism nor thyroid carcinoma recurred. Conclusion It is difficult to make diagnosis of hyperthyroidism with thyroid carcinoma preoperatively. B mode ultrasonography may find some nodes in enlarged thyroid; but fine needle aspisation biopsg(FNA) has high false negative diagnostic rate. Intra-operative frozen section examination is important in the diagnosis of hyperthyroidism with thyroid carcinoma .

75%(more than 2-vessel disease) and 50 persons with angia and non-diabetes were selected as control.Results The level of NT-proBNP was significantly higher in stable angina patients with diabetes(750?80 ng/L) than that in stable angina patients without diabetes(450?75 ng/L)(P
