ObjectiveTo determine the influence of buspirone on sexual function and plasma prolactin in rehabilitative female major depressive patients.MethodsThe female major depressive patients,who had a total HAMD-17 less than 7,were living with a sexual partner and receiving SSRI antidepressant monotherapy for at least six months were recruited.Sexual dysfunction (SD) was assessed using the Arizona Sexual Experience Scale (ASEX).The patients with SD were treated with buspirone 15 ～ 30 mg by 4 weeks.Sexua function and blood samples were compared among the control,non-SD patients,and the SD patients before or after treating with buspirone.The clinical risk factor of SD was also investigated with correlation analysis.ResultsThe general incidence of SD in rehabilitative female major depressive patients was 33.3％.The improvement rate of SD was 60％ after the treatment of buspirone.The ASEX score and it 5 items were significantly decreased in the depressive patients after the treatment of buspirone (P ＜ 0.01 ).Prolactin in subjects treated with buspirone ( ( 20.38 ± 11.91 )ng/ml) was significantly higher than control ( ( 14.2 ± 12.15 ) ng/ml),but not higher than the period prior to treatment with buspirone ( ( 18.15 ±9.84) ng/ml).The ASEX score was significantly correlated the dose of fluoxetine( r=0.504,P=0.002) and paroxetine ( r=0.377,P=0.013).There was no significantly correlation between ASEX score and prolactin in the control,non-SD patients,and the patients before or after treating with buspirone.ConclusionBuspirone can release sexual dysfunction induced by SSRI antideptressant in the depressive patients.

Objective:To explore the efficacy and safety of different surgical methods in papillary thyroid carcinoma (PTC) patients with negative cervical lymph nodes (cN0) and to provide theoretical basis for the selection of surgical procedures. Methods:A total of 225 PTC cN0 patients were selected and divided into two groups according to the operation method. Only 110 patients underwent total thy-roidectomy, whereas the 115 cases in the lobectomy group underwent ipsilateral lobectomy and isthmus resection. Al patients were treated with ipsilateral central lymph node dissection. We analyzed both groups of patients in terms of surgery, hospitalization, pathological characteristics, complications, follow-up, and recurrence. Results:(1) The length of incision, blood loss, operation time, and length of stay were not significantly different between the two groups (P>0.05). (2) In the total resection group, the number of multiple foci of the cancer cases was significantly more than that of the lobectomy patients (P<0.05). The average tumor diameter in both groups were not significantly different (P>0.05). Between the two groups, the number of central lymph node dissection and total lymph node metastasis, and the number of cases with central lymph node metastasis were not significantly different (P>0.05). Likewise, the incidence rates of mistakenly cut parathyroid, extremely low blood calcium levels, temporary larynx return nerve paralysis, and superior laryngeal nerve injury were not significantly different between the two groups (P>0.05). No permanent hypocalcemia or permanent recurrent laryngeal nerve injury occurred. (3) All patients were followed up for 2-4.5 years. No recurrent cases were reported in the total resection group. For the lobectomy group, 8 patients with adenocarcinoma had contralateral tumor metastasis and underwent contralateral lobe resection, whereas 4 patients suffered from ipsilateral neck lymph node metastasis at the side area and underwent functional lymph node clearance. Significant differences were noted in the metastasis and recurrence rates between the two groups of patients (P<0.05). No deaths were reported during the follow-up period. Conclusion:For PTC cN0 patients, total thyroidectomy with joint ipsilateral central lymph node clearance can reduce the residual tumor, metastasis, and risk of recurrence,compared with surgery limited to the affected lobe and isthmus. Postoperative complications were not significantly increased.

Objective To observe the effect of ischemic postconditioning on neuron structure plasticity and memory after global cerebral ischemia injury in rats and discuss the protection mechanism from aspect of Morphology. Methods A total of 36 SD male rats were randomly divided into sham operation group, global cerebral ischemia for 15 min group and global cerebral ischemia plus postconditioning group, 12 rats per group. The pullsinelli 4 vessel occlusion was applied to produce the models of global cerebral ischemia reperfusion injury, common carotid arteries (CCA) occlusion with 15 min and postconditioning with three cycles, of 15 sec release and 15 sec occlusion (15s/15s). Six rats from each group were evaluated by Morris Maze test for the ability of space learning and memory and the other six rats were evaluated by golgi stain for morphologic change of neuron. Results The ischemic postcondtioning group showed significant shorter mean escape latency compared with the sham operated group ( at day 3, P =0. 014; at day 4, P =0.040; at day 5, P =0.001 ). The density of dendritic spine in ischemic postcondtioning group was increased more significantly compared with ischemic group ( F = 562. 820,P ＜ 0. 01 ). Conclusion Ischemic postconditioning has obvious protective effect on cerebral ischemiainduced memory impairment, which may be related to alleviation of dendritic spine injury.

ObjectiveTo evaluate the clinical efficacy and safety of astragalus injection on the immune function in patients with senile sepsis.Methods Sixty patients with old age sepsis in Critical Care Medicine Department of Guangdong Provincial Traditional Chinese Medicine Hospital were enrolled and randomly assigned into control and treatment groups according to the table of random numbers, 30 cases in each group. According to 2012 sepsis guidelines for treatment, including antibacterial drug, mechanical ventilation, visceral function support, etc., the therapy was given to the control group; besides the treatment in the control group, intravenous drip of 60 mL astragalus injection(10 mL per ampoule) in 250 mL 0.9% normal saline was additionally given in the treatment group, once a day for 7 days. Before and after treatment, the immunological indexes, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment(SOFA) score, duration of mechanical ventilation and time of stay in intensive care unit(ICU), 28-day mortality and adverse drug reactions were compared between the two groups.Results Before treatment, there were no statistically significant differences in CD3+, CD3+CD4+, CD3+CD8+ and T helper cells /T suppressor cells(Th/Ts)levels between the two groups(allP>0.05), while CD3-NK+ of the control group was significantly higher than that in the treatment group〔(10.47±6.22)% vs. (6.26±4.13)%,P<0.05〕. After treatment in treatment group, CD3+, CD3+CD4+ and CD3-NK+ were increased, CD3+CD8+,Th/Ts were decreased compared with those before treatment; in the control group after treatment, CD3+,CD3+CD8+ and CD3-NK+ were decreased and CD3+CD4+ and Th/Ts increased compared with those before treatment. In the comparisons between the treatment group and control group after treatment, the differences in CD3+, CD3+CD4+ and CD3+CD8+ had statistical significance〔CD3+:(30.30±17.17)% vs.(41.91±22.29)%, CD3+CD4+:(31.54±13.24)% vs.(40.08±15.28)%, CD3+CD8+:(14.25±8.10)% vs.(9.52±9.33)%,allP<0.05〕; while the differences in Th/Ts and CD3-NK+ had no statistical significance(bothP>0.05). After treatment in the treatment group, IgG was increased compared with that in the control group〔IgG(g/L): 13.07±5.43 vs. 10.10±3.96,P<
0.05〕. The differences in IgA, IgM, complement(C3,C4) and total serum complement activity(CH50) in the comparisons between the two groups had no statistical significance after treatment(allP>0.05). The differences in APACHEⅡ score(13.83±6.18 vs. 15.90±7.48), SOFA score(7.38±4.66 vs. 6.89±4.19), time of stay in ICU(day: 11.63±5.13 vs. 13.62±8.08), invasive ventilation time(hour: 155.44±119.68 vs. 224.08±174.15) and noninvasive ventilation time(hour: 55.55±42.24 vs. 98.57±43.17) had no statistical significance in comparisons between the treatment group and control group after treatment(allP>0.05). The difference in 28-day mortality had no statistical significance in comparison between the treatment group and control group〔16.7%(5/30) vs. 20.0%(6/30),P>0.05〕. In 60 cases, there were 2 patients with adverse drug reaction, one diarrhea and another little rashes, the rest of the patients did not appear any drug side effect.ConclusionAstragalus injection combined with conventional western medicine therapy possibly has certain effect on adjustment of disturbance of immunologic functions in old patients with sepsis, and its therapeutic safety is well.

AIM: To approach the antiobesity action and mechanisms of the daidzein derivative: LRXH609(LRX).METHODS: The body weight,Lee′s index,total weight of celiac fat tissue,food intake,serum glucose and lipids in obese rats induced by a high-fat diet were measured and the antiobesity action was tested after LRX was administered for 30 days.3T3-L1 pre-adipocytes were induced by in vitro culture,the effects of LRX on cell proliferation,lipogenesis,lipolysis were observed.RESULTS: The body weight,Lee′s index,fat tissue weight in obese rats were significantly decreased by LRX,and the concentrations of TC,FFA in serum were decreased,the proliferation of 3T3-L1 pre-adipocytes was inhibited,the activities of hormone sensitive lipase in 3T3-L1 pre-adipocytes were significantly elevated,the glycerine release from adipocytes was promoted and the concentrations of TG in adipocytes were decreased.CONCLUSION: LRX plays a role in antiobesity action and regulating blood lipid and the mechanism might be related to inhibiting proliferation and differentiation of pre-adipocytes,stimulating TG decomposition by activating hormone-sensitive lipase and decreasing the TG storage in adipocyte.

Objective To study the role of RICTOR on rheumatoid arthritis-fibrobast-like synoviocytes (RA-FLS) activation.Methods FLS were isolated from the primary synovial tissues,which were obtained during joint replacement surgery or arthroscopy from three patients with RA.RA-FLS were stimulated with TNF-α at the dose of 10 ng/ml and 20 ng/ml for 48 h.The expression of RICTOR was detected by western blotting.Chemically synthesized RICTOR gene targeted for double-stranded siRNAs were transfected into RA-FLS by cationic liposome.After being transfected with RICTOR siRNA for 48 h,RA-FLS was treated with or without TNF-α for 48 h.The expression of RICTOR was evaluated by western blotting,and the cell viability was analyzed by methylthiazoltetrazolium (MTT) assay.The data were analyzed using analysis of variance (ANOVA) and LDL-t test.Results The expression of RICTOR protein was significantly higher in the TNF-α stimulated group (at the dose of 10 ng/ml and 20 ng/ml for 48 h) than that in the control group (bothP＜0.05),while the mean change of RICTOR/GAPDH ratios of band optical density x+s was 0.35±0.06 for the control group,0.60±0.09 for the TNF 10 ng/ml group and 1.10±0.12 for the TNF 20 ng/ml group.Moreover,the expression of RICTOR protein was obviously decreased in RICTOR siRNA transfection groupthan that in control after being trans-fected for 96 h (both P＜0.05),and ratios of control group,RICTOR (-)/TNF-α(-) group and RICTOR(-)/TNF-α(+) group was 0.498 4±0.140 1,0.012 8±0.002 0,0.042 5±0.027 3respectively.After the silence of RICTOR,the cell viability decreased in RA-FLS,no matter with or without TNF-α for 48 h later (both P＜0.05).Conclusion These results indicat that RICTOR might play an important role in the TNF-α associated activation of RA-FLS.

Objective: To investigate the expression of peroxisome proliferator actived receptor ? (PPAR ?)and the inducement of apoptosis by PPAR ? ligand in renal cell carcinoma(RCC) derived cell lines.Methods:RT-PCR and Western blot analysis were performed to determined the expression of PPAR ? mRNA and protein in two RCC derived cell lines(786 O and A498) and two normal kidney(NK) derived cell lines(HK 2 and HMCC). Two RCC cell lines were treated with 50 ?mol/L troglitazoned for and evaluated for the effects of antidiabetic thiazolidinediones (TZDs) on the cells apoptosis by fluorescence microscopy and DNA ladder assay.The mutative expressions of Bcl 2 and Bax before and after TZDs treatment were also performed by western blot analysis. Results: The expression of PPAR ? was observed to be stronger in 786 O and A498 cells than in HK 2 and HMCC cells by RT-PCR and Western blot analysis. Treated with 50 ?mol/L troglitazone (for 48 h) it induced typical apoatosis in 786 O and A498 cells. After treatment, a decrease in Bcl 2 expression in RCC cells was observed by Western blot analysis,and the expression of Bax,however,was up regulated.Conclusion: The results reveal that troglitazone has the tumor suppressive effect on RCC cells. High affinity PPAR ? ligands (TZDs) may be the candidates for a novel approach to the treatment of this refractory neoplasm.

Objective To compare the clinical features of drug induced hepatitis caused by traditional Chinese medicines (TCM) and western medicines. Methods A total of 181 patients hospitalized with drug in-duced hepatitis between January and December 2015 were enrolled. Among the patients ,75 cases were in TCM group,66 cases in western medicine group and 40 cases in combined group(accepted both TCM and western medi-cine treatment). Liver biopsies were performed and Roussed Uclaf Causality Assessment Method (RUCAM) scores showed that all patients were with scores higher than 3. The data including gender,age,clinical manifesta-tions,physical signs,laboratory tests and image characteristics were analyzed individually. Results There was no significant difference in age,the pattern of liver injury,and the course of liver damage among the three groups (P>0.05). Anorexia was common symptom in all the three groups without any significant difference(P>0.05). Jaundice was most frequently observed in TCM group while fever was most commonly found in western medicine group,which both had significant difference(P< 0.05). The results of routine coagulation tests and serum albu-min values were normal in 3 group with increasing level of aminotransferase observed ,and there was no significant differences among 3 groups(P>0.05). Compared with western medicine group ,the patients in TCM group had a higher level of platelet counts ,serum levels of total bilirubin ,total bile acids(TBA)and serum iron(P<0.05), and less proportion of eosinophils and lower level alkaline phosphatase(P< 0.05). Conclusions The age,the pattern of liver injury,the course of liver damage and aminotransferase levels in patients with drug induced hepati-tis caused by TCM and western medicines were similar;however,western medicines were more likely to cause al-lergic responses and hyperbilirubinemia occurred more frequently in patients with drug induced hepatitis caused by TCM.
