1.The validity of experimental animal models of depression
Chinese Journal of Pathophysiology 1999;0(09):-
Study of depression and antidepressant drugs mainly depends on animal models. Twelve animal models of depression related to some sets of validating criteria are reviewed. Of the 12 models, some traditional models (reserpine reversal, amphetamine potentiation) are rejected as they are devoid of selectivity, insufficient to predict antidepressant activity in the compounds tested. The models with the highest overall validity are the intracranial self-stimulation, chronic stress and learned helplessness models in rats, and the primate separation model. A combination of several models may be the best way to study depression and to screen antidepressant drugs. This combination can be used to detect compounds comparable to those antidepressants possessing clinically established antidepressant activity.

AIM: To study the liver protective hypolipidemic function of Artemisia capillaries Thunb on the fatty liver rats with insulin resistance of action. METHODS: Adult SD rats were maintained by high-fat-sugar-salt diet for 8 weeks,and extraction of Artemisia capillaries Thunb(high dosage 6.9 g/kg,low dosage 2.3 g/kg) was administered to the rats for 4 weeks by intragastric administration at the begining of 9~(th) week.And then all animals were killed and the blood was sampled to measure the levels of blood glucose,blood lipid(TC,TG,HDL-C,LDL-C,FFA),fasting serum insulin and the levels of MDA and TGF-?_1.The activities of ALT,AST and SOD also were measured.The liver was weighed and collected to observe the pathological changes. RESULTS: Compared with model rats,the levels of blood glucose and insulin decreased significantly in the treatment of Artemisia capillaries Thunb,and insulin sensitivity index returned to normal condition(P

Objective:To compare short-term and long-term curative effect of modified double Kirschner wire open reduction and internal fixation (ORIF) and traditional surgery on patients with mallet fingers of avulsion fracture type.Methods:Eighty-five patients with mallet fingers of avulsion fracture type who were admitted to Yongkang Orthopaedic Hospital from January 2016 to October 2018 were enrolled. 45 patients received modified double Kirschner wire ORIF were included in the observation group, while 40 patients who underwent traditional extracting wire fixation were included into control group. The operation time, fracture healing time and complications were recorded. At 3 months after surgery, short-term curative effect was evaluated. After 1-year postoperative follow-up, long-term prognosis was evaluated by finger joint function scoring.Results:The operation time of observation group was shorter than that of control group ( P<0.05). The fracture healing time of observation group was shorter than that of control group ( P<0.05). The good rate of observation group was higher than that of control group (93.33% vs 77.50%) ( P<0.05). In finger joint function score, scores of finger strength, finger flexibility, effects on work and life, and total score in observation group were higher than those in control group ( P<0.05). There was no significant difference in pain degree or appearance satisfaction betwen the two groups ( P>0.05). There was no significant difference in incidence of postoperative complications between the two groups ( P>0.05). Conclusions:The modified double Kirschner wire ORIF for the treatment of avulsion fracture mallet finger has the advantages of simple operation, fast fracture healing and better long-term and short-term curative effect than the traditional wire extraction method.

In order to obtain more experience of endoscopic retrograde cholangiopancreatography (ERCP) ,and in this way, more correct diagnosis and much more effective treartment were received ,we studied 1 257 cases of ERCP we had performed in last two years . The results were: In 1 25 7 cases of ERCP,1 229 cases(97. 77% ) were successful and 435 cases (34. 61% ) received treatment. Ninety-four cases received papillotomy and extraction, 309 cases received biliary drainage in therapeutic ERCP. lt in- dicated that the importance of gallbladder visualization and biliary drainage should be emphasised.

Objective To evaluate the effects of different surgical treatments on severe polycystic liver disease (SPLD). Methods A total of 22 patients with SPLD were surgically treated in our Department from December 1989 to July 1999. Of the patients, 5 were treated with the partial hepatic resection in combination with cyst fenestration (group A), 7 with laparotomic fenestration (group B), 4 with laparoscopic fenestration (group C) and 6 with puncture under the guidance of ultrasonography B (group D). The surgical outcome and long term follow up results were retrospectively analyzed. Results After the treatments, all the patients experienced immediate relief of symptoms. However, the follow up for an average of 3 years showed that 10 patients developed recurrence of the disease. The recurring rates were 0, 28.5%, 65.5% and 100% in groups A, B, C and D, respectively. Conclusions The approach of partial hepatic resection in combination with cyst fenestration is the most effective treatment for SPLD. Laparoscopic fenestration may not be an appropriate surgical way for treatment of SPLD.

Objective To examine the expression of follistatin-like protein 1 (FSTL1) in the peripheral blood and intestinal mucosa tissues of ulcerative colitis (UC) patients and analyze the correlation between its expression and the activity of UC.Methods From October 2010 to June 2012,sixty patients with UC were collected.From April 2012 to October 2012,thirty individuals without any obvious mucosa lesion under colonoscope and confirmed by pathological examination were set as control group.The serum expression level of FSTL1 of both UC group and control group were determined by enzyme linked immunosorbent assay (ELISA).t-test was performed for comparison between groups.The expression of FSTL1 in the intestinal mucosa of UC group and control group was detected by immunohistochemistry.Chi-square test was used for comparison between groups.The patients with UC were scored with ulcerative colitis disease activity index (UCDAI).Its correlation with plasma FSTL1 was analyzed by Pearson correlation coefficient.Results The serum expression level of FSTL1 of UC group ((14.37-±-1.80) μg/L) was higher than that of control group ((5.80±0.72) μg/L)and the difference was statistically significant (t=25.01,P< 0.05).The serum expression level of FSTL1 of UC group was positively correlated with UCDAI (r=0.814,P<0.05).The positive expression rate of FSTL1 in the intestinal mucosa tissues of UC group (86.7%,52/60)was higher than that of control group (46.7%,14/30) and the difference was statistically significant (x2 =52.334,P<0.05).Conclusions The expression of FSTL1 of UC patients increases and is positively correlated with disease activity.FSTL1 may play a role in the development of UC.

OBJECTIVE: To determine the protective effects of nourishing spleen yin recipe (Zibu Piyin Recipe, ZBPYR), a compound traditional Chinese herbal medicine, on endoplasmic reticulum (ER) in neuronal cells responding to the stress by using sero-pharmacological method. METHODS: The mouse neuroblastoma cell line Neuro2a cells were treated with tunicamycin (Tm, an inhibitor of N-glycosylation). The ZBPYR-treated cell group was established by incubating cells with ZBPYR serum for one hour and treated with Tm. Reverse transcriptase PCR (RT-PCR) was utilized to detect the mRNA expressions from two genes after treatments, ER molecular chaperone glucose regulated protein 78 (GRP78) and transcriptional factor CCAAT/ enhancer-binding protein-homologous protein (CHOP). Lactate dehydrogenase (LDH) assay was also carried out to determine the LDH leakage from Neuro2a cells after treated with Tm and staurosporine (STS). RESULTS: The ZBPYR-treated cell group at all tested ZBPYR dosages showed significantly reduced expressions of both genes compared with Tm (5 microg/ml) treated control group (P<0.05). Therefore, ZBPYR serum inhibited the expressions of GRP78 and CHOP in mRNA level under ER stress induced by Tm. Different concentrations of ZBPYR serum pretreatment reduced the LDH leakage compared with the Tm and STS groups (P<0.05). Therefore, ZBPYR serum may inhibit the LDH leakage induced by Tm and STS. CONCLUSION: ZBPYR has neuroprotective effects. The mechanisms may be associated with inhibition of ER stress and mitochondrial dysfunction.
