Objective:To investigate depression of elderly patients in general hospital Method:315 patients aged 60 or above in Tongji hospital were screened with CES-D (Chinese version of Center of Epidemiological Survey-Depression) Results:70 of them (22%) definitely had depression, 53 were suspected of depression Female had higher scores in CES-D than male The less educated had higher score in CES-D Multiple regression showed poor education as a risk factor for depression in elderly patients Discussion: Routine screening for depression in elderly patients in general hospital is necessary

Objective To detect Nogo-A proteolytic fragment in CNS injury models and investigate its proteolytic mechanism as well as potential functions. Methods Western blot was performed to detect Nogo-A proteolytic fragment after spinal cord transection,brain ischemia and KA-induced cerebral cortex injury in rats. Results We detected Nogo-A proteolytic fragment in spinal cord transection and brain ischemia models,whereas no Nogo-A proteolytic fragment was found in KA-induced cerebral cortex injury model.Conclusion\ CNS mechanical and ischemic injury may induce the degradation of Nogo-A by certain mechanisms.

AIM:To evaluate the therapeutic effect of limaixian on genitourinary infections.METHODS:98 cases of genitourinary infections were randomly divided into 3 groups:treatment group,limaixian 250mg bid;control group A,roxithromycin 150 mg bid;control group B,amoxicillin 500mg tid.The therapeutic courses of 3 groups were 7 days.RESULTS:The total effective rate,pathogenic microbe clearance and adverse drug reactions(ADRs) in treatment group were 82.86％ ,81.82％ and 2.86％ respectively.The results were better than those in control group A and B.CONCLUSION:Limaixian is satisfactory in effect,mild in ADRs and broad in antimicrobial spectrum for treatment of genitourinary infections.It is worth extending.

The 50% inhibition doses ( ID50 ) of tetrandrine and demethyl tetrandrine on DNA synthesis in L7712 and Sl80 cells are 2.6, 3 .5mg/ L and 27.5, 24.5mg/L respectively. The DNA synthesis inhibition is likely due to DNA template damage caused by both natural products. The inhibition of DNA, RNA and protein syntheses by tetrandrine or demethyl tetrandrine increased with incubating time. The inhibiting activities of two natural products on DNA and RNA synthesis are s-tronger than on protein. There are no differences either in inhibiting activity or in inhibiting mechanism between two natural products.

Objective To evaluate the impairment of ulnar nerve and its relationship with sensory symptoms in the ulnar territory in patients with carpal tunnel syndrome (CTS) through electrophysiological approach.Methods We retrospectively reviewed 55 cases with CTS admitted in our hospital from January 2012 to February 2013.Patients with CTS were graded as mild-moderate (35 cases) and severe (20 cases) according to Stevens standard and were divided into symptomatic and non-symptomatic group according to the presence of sensory symptom in little finger region.Twenty healthy volunteers were included as control.Median and ulnar nerves electrophysiological study were performed using the Keypoint.net (Medoc Ltd) electromyogram device.Results Finger 5-wrist sensory conduction velocities (SCVs) of ulnar nerve were reduced ((51.71 ± 2.93) m/s vs (58.62 ± 3.21) m/s,t =8.80,P ＜ 0.01) in CTS group,compared with control group.But the sensory nerve action potential (SNAP) amplitudes had no difference.Pearson correlation analysis showed that finger 5-wrist SCVs and the SNAP amplitudes of ulnar nerve were negatively correlated with the distal motor latency of the median nerve,while positively correlated with the compound muscle action potential amplitudes,finger 1-wrist,finger 3-wrist SCVs and SNAP amplitudes of median nerve,in mild-moderate group,finger 5-wrist SCVs of ulnar nerve were slowed and the SNAP amplitudes were reduced ((51.59 ±2.70) m/s vs (53.72 ±2.58) m/s; (13.51 ± 1.84) μV vs (15.21 ±2.16) μV,t =2.24,2.30,P ＜ 0.05 respectively) in the symptomatic group,compared with the non-symptomatic group.However,in severe group,only 2 cases had sensory symptom in little finger region.Conclusions CTS patients may have impairments due to ulnar nerve entrapments at wrist,which aggravate with disease progression.Sensory symptoms in ulnar territory are more frequent during the mild-moderate stage,and may relate with ulnar nerve involvement.

Objective To assess the effects of radiofrequency ablation (RFA) and bipolar cord coagulation (BCC) on the prognosis and complication rate of complicated monochorionic twins.Methods A retrospective review was undertaken in 58 cases of complicated monochorionic twins treated with RFA or BCC at the First Affiliated Hospital of Sun Yat Sen University,from January 2008 to August 2013.Non-parametric Wilcoxon test,Chi-square test,Fisher exact test or multi-variant Logistic regression analysis were used for statistical analysis.Results Indications for selective termination in the 58 cases were:twin reversed arterial perfusion sequence in 12,severe twin to twin transfusion syndrome in 28,discordance of fetal anomalies in 10,selective intrauterine growth restriction in 7 and twin anemia-polycythemia sequence in 1.Forty-three cases were managed with BCC and 15 with RFA.Preterm labor was more common in the BCC group than in the RFA group [86.0％(37/43) vs 9/15,respectively; x2=4.598,P=0.032).Premature rupture of the membranes occurred in 48.8％(27/43) of the BCC group vs.4/15 of the RFA group (x2=2.229,P=0.135).The median procedure-todelivery time was 48 (1-150) days for the BCC group vs.101(14-138) days for the RFA group (Z=-2.245,P=0.025).Overall survival rate was 62.8％(27/43) in the BCC group vs 11/15 in the RFA group (x2=0.547,P=0.460),which was not significantly different.Neurodevelopmental delay was detected in two neonates in BCC group and in one neonate in RFA group.Logistic regression analysis showed that delivery before 28 gestational weeks was an independent risk factor for the poor prognosis of the co-twins (OR=192.720,95％CI:18.610-994.000,P ＜ 0.01).Conclusion Compared with BCC,RFA does not improve the prognosis of complicated monochorionic twins significantly.

Platelet activating factor (PAF) is a biologically active membrane phospholipid mediator. In this study we investigated the effects of PAF on the lymphocyte proliferation, production of IL-2, natural killer cytotoxic factor (NKCF) and colony stimulating factor (CSF) by BALB/c mice splenocytes in vitro. The results showed that PAF inhibited lymphocyte proliferation at concentrations of 10-10~ 10-7 mol/L. CTLL-2, YAC-1 and munne bone marrow cells were used for the assays of IL-2, NKCF and CSF, respectively. Production of IL-2, NKCF and CSF from ConA stimulated murine splenocytes was significantly inhibited by PAF at 10-7 mol/L. Inhibition of spleen cells proliferation and secretion may play an important role in the pathological effects of PAF.

Objective To study the relationship of sunlight exposure and photoprotection with clinical activity in systemic lupus erythematosus. Methods A structured questionaire was administered to 107 SLE patients, to assess their attitudes and behavior regarding sunlight exposure and photoprotection. The clinical manifestations, laboratory findings and treatment were evaluated. Results All patients were classified into two groups based on the duration of exposure to sunlight per day. Fourty-eight (44.86%) patients were exposed to direct sunlight for an average of less than one hour per day in one group and 59 (55.14%) for one hour or more in the other group. Twenty-four (22.43%) patients reported use of photoprotective measures in spring and summer. The patients in the former group had significantly lower incidences of photosensitivity, arthritis, alopecia, exacerbations, presence of anti-dsDNA antibody, decrease of complement C3, C4 and CH50 than those in the latter group(P

Objective To investigate the therapeutic effects of curcumin(Cur)on trinitrobenzene sulphonic acid(TNBS)induced colitis and to investigate cytokines change in colon mucosa,spleen and sera.Methods Colitis was induced in SD rats by intrarectal injection of TNBS(100 mg/kg).Experi- mental animals were divided into negative control group,TNBS group and Cur therapeutic group(Cur, 30 mg?kg~(-1)?d~(-1),intraperitoneal injection).Expression of cytokines mRNA in colon mucosa was observed by RT-PCR,intracellular cytokines of interferon(IFN)-?and interleukin(IL)-4 in splenocytes were detected by flow cytometry(FCM),concentrations of IFN-?and IL-4 in sera were determined by enzyme-link immunosorbent analysis(ELISA).Results After treatment with Cur,macroscopic scores (3.9?1.0 vs.2.2?0.7),myeloperoxidase(MPO)activity(15.0?2.6 vs.7.3?1.4),mRNA of IFN-?(1.02?0.07 vs.0.06?0.02,mRNAof IL-12(0.29?0.05 vs.0.11?0.01)and the ratio of IFN-?/IL-4(11.44?0.97 vs.0.38?0.10)in colon mucosa,proportion of IFN-?CD4~+(31.7?7.5 vs. 21.1?3.7)and the ratio of IFN-?/IL-4 CD4~+(19.9?5.1 vs.6.1?1.8)in splenocytes,concentra tions of IFN-?[(1528?159)pg/ml vs.(513?14)pg/ml] and the ratio of IFN-?/IL-4(19.5?4.1 vs. 4.2?0.6)in sera were all decreased(P＜0.05 or P＜0.01).Meanwhile,mRNA of IL-4(0.09?0.01 vs.0.15?0.04)and IL-10(0.28?0.08 vs.0.63?0.12)in colon mucosa,proportion of IL-4 CD4~+ (1.6?0.5 vs.3.4?1.1)in splenocytes and concentrations of IL-4 in sera[(81?15)pg/ml vs.(124?20) pg/ml] were all increased after the treatment of Cur(P＜0.05 or P＜0.01).Conclusions Cur showed ther- apeutic effects on TNBS-induced colitis,and the mechanism might be through regulating the balance of Th1/ Th2 in colon locally and systematically.
