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

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 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.

Currently, the resistance of first-line anti-tuberculosis drugs has made the prevention and treatment of tuberculosis increasingly difficult, posing a serious threat to global public health. Several studies have shown that efflux pumps are one of the important causes for bacteria to develop multi-drug resistance and extremely-drug resistance, and efflux pump inhibitors can inhibit the efflux of antibacterial drugs, thereby reducing bacterial drug resistance. Numerous natural products and synthetic compounds have been reported to possess efflux pump inhibitory activity, but they have not been applied in clinical settings because of their toxicity, pharmacokinetic properties, etc. Therefore, we summarized the efflux pump inhibitory activity, antimicrobial activity, and structure-activity relationships of reported efflux pump inhibitors against Mycobacterium tuberculosis in recent years, providing references for the development of new efflux pump inhibitors with better activity and lower toxicity.

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 reassess the value of CT and clinical criteria as prognostic and severity indicators in acute pancreatitis and to investigate the correlation between them.Methods Of 65 cases of acute pancreatitis,the hospitalization days,fevering days and entire complications (including local and systemic complications)were regarded as clinical endpoints.CT criteria included Balthazar's plain CT scan score,necrosis score,CT severity index(CTSI) and London's PSI score.Clinical criteria included Ranson and APACHE Ⅱscore.Using analysis of variance,t-test and multiple linear regression analysis,the correlation between each criteria and the three clinical endpoints was examined as well as the relation between CT and clinical criteria.The power of each criteria and combination of CT and clinical criteria in predicting entire complications of AP was assessed and compared by using ROC analysis.Results The mean scores of PSI,Ranson and APACHE Ⅱamong three groups classified according to entire complications were significantly different.Except Balthazar's plain CT scan criteria,each criteria's mean scores in group with local complications was signifiantly higher than that in group without and entire complications was significantly more in sever group than that in mild group.Mean hospitalization days and fevering days were significantly longer in sever group than that in mild group with Ranson Score.PSI and Ranson score had linear correlation with fevering days,and Ranson score had linear correlation with hospitalization days.In CT criteria,a linear correlation was only found between PSI and Ranson score.ROC analysis showed the Az of Ranson score was the largest,and there was no increase in the Az when CT criteria were added to clinical criteria.Conclusion The predictive value of Ranson score and PSI are superior to that of others.Clinical criteria is superior in predicting systemic complications,whereas CT is superior in predicting local complications.There is no improvement in predicting entire complications of AP when CT criteria are added to clinical criteria.The findings of plain CT scan is found to be some laggard compared with that of clinic.CT scan and short follow-up are important in the evaluation of AP.

Objective To compare open versus closed reduction in treatment of children with displaced femoral neck fracture whose reduction is delayed by more than 24 hours.Methods We retrospectively reviewed 51 children who had been treated at our department for femoral neck fracture between May 2005 and May 2012 after their reduction had been delayed for more than 24 hours.They were 37 boys and 14 girls,1.7 to 15.5 years of age (average,9.1 years).According to Delbet's classification,27 cases belonged to type Ⅱ,18 to type Ⅲ,and 6 to type Ⅳ.Of them,18 underwent closed reduction and 33 open reduction.Their complications were recorded in detail.Their therapeutic results were evaluated according to Ratliff's criteria and compared between the 2 methods of reduction.Results The 51 children were followed up for an average of 36.7 months (range,from 17 to 61 months).Anatomic reduction was achieved in 6 cases in the closed reduction group (33.3％) and 29 cases in the open reduction group (87.9％),respectively.All fractures healed after an average of 10.9 weeks (range,from 9 to 13 weeks),with one exception of nonunion in the closed reduction group.The incidence of femoral head necrosis in the closed reduction group (27.8％,5/18) was significantly higher than that in the open reduction group (15.2％,5/33) (P ＜ 0.05).According to the Ratliff's evaluation at the final follow-ups,the good to excellent rate in the closed reduction group(66.7％,12/18) was significantly lower than that in the open reduction group (84.8％,28/33) (P ＜0.05).Coxa vara occurred in 3 children in the closed reduction group but in none in the open reduction group.Conclusion Open reduction with internal fixation may lead to better outcomes than closed reduction in the treatment of children with displaced femoral neck fracture whose reduction is delayed by more than 24 hours,probably because open reduction can result in better reduction quality.

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
