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.

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.

Conclusion: The augmentation of mRNA expression of IL-6 and IL-8 maybe regarded as the mark of rhinits in IL PR.

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.

Objective To investigate the prevalence, clinical characteristics and antibiotic resistance of Haemophilus influenzae (HI) in children with acute respiratory tract infection in Suzhou. Methods Data of sputum culture of 3 167 hospitalized childhood patients with acute respiratory tract infection from January 2006 to December 2007 were collected. The incidence of positive HI and the rate of resistance to different antibiotics were calculated and beta-lactamases of the strains were detected. Results About 4.4% of total 3 167 eases were infected with HI. The infection rate was related with season and sex, more frequent between February and June, more common in boys than girls. Children younger than three years old were likely to be infected by HI, eompared with other age groups. The beta-lactamase positive rate of HI was 31.4%. The resistance rates to ampicillin, SMZ + TMP, chloramphenicol, cefaclor, ceftazidime, tetracycline and ampicillin/sulbactam were 29.6% ～ 31.9%, 66.2% -73.9%, 19.7% ～ 15.9%, 2.8% ～ 14.5%, 2.8% ～0、 28.2% ～ 2.9% and 4.2% ～ 1.4% respectively. Isolates resistance to cefuroxime、 ceftriaxone、 imipenem、azithromycin and ciprofloxacin were not found. Conclusions The infection of HI in children with actue respiratory tract infection is closely related with season and sex in Suzhou. Children younger than three years old are at high risk. The beta-lactamase positive rate of HI was high and increased rapidly. Resistance rate to azithromycin, SMZ + TMP and chloramphenicol was high, some isolates were resistant to the second, third generation of cephalosporin. Monitoring the antibiotic resistance of H! should be emphasized.

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.
