Objective To investigate the effect of depression on the incidence of osteoporosis in patients with maintenance peritoneal dialysis (MPD).Methods We enrolled 80 MPD patients,who underwent peritoneal dialysis in our dialysis center.The clinical data and biochemical parameters of all patients were collected,bone mineral density was detected and the Self-rating depression scale was used to evaluate depression state.Results Among the 80 enrolled MPD patients,34 patients had osteoporosis (42.5％),48 patients had the presence of depression (60％).Logistic regression analysis showed that age,dialysis age,gender,diabetes history and depression state were the risk factors for osteoporosis in MPD patients,the depression state was negatively correlated with BMD of lumbar and femoral neck (r=-0.347,r=0.426,P＜0.05).Conclusion Depression state may be a risk factor for osteoporosis in clinic,it is of great significance to focus on the psychological state of MPD patients in the prevention and treatment of osteoporosis.

In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

Objective To analyze the electrocardiography(ECG)data of pressure overload-induced cardiac hy pertrophy rats.Methods Pressure overload cardiac hypertrophy was induced by abdominal aorta constriction. Echocardiogram and heart weight measurement demonstrated the occurrence of cardiac hypertrophy.Standardized ECG parameters of limb and chest were measured and statistically analyzed.Results Two weeks after hypertrophy models were established,echocardiogram showed greater LVPWTd,IVSTd,LVDd.ECG showed that left axis deviation and higher R waves in V_A,V_B,V_C(P

Objective To evaluate the effectiveness of arthroscopically assisted percutaneous reduction and internal fixation with eannulated screws.Methods The fracture was reduced by closed manipulation or percutaneous leverage force by using the Kirschner wire.Then the patella was temporarily fixed by using a large size towel clamp or Kirschner wires.Under the guidance of knee arthroscopy,a micro-incision was made at the size of cannulated screw placement,the pilot holes were drilled at a proper depth,and the thread was configured.Two titanium screws were inserted parallelly.Results Following-up chekups for 4～24 months in 18 cases showed a satisfactory recovery of knee functions.According to the Bostman' standard,excellent effects were obtained in 16 cases and good effects in 2 cases.Conclusion Treatment of patellar fractures by percutaneous cannulated screw fixation under arrhroscope of- fered advantages of minimal invasion,accurate reduction,reliable fixation,and excellent recovery of joint functions.

Objective To study the effect of chest wall vibration therapy on bronchiolitis. Methods A total of 64 patients with bronchiolitis were divided into an experimental group and a control group, the former included 34 cases and the latter included 30 cases. The experimental group received both routine treatment and chest wall vi- bration, while the control group only received routine treatment. PaO_2, PaCO_2, SaO_2, Heart Rate (HR) and Respi- ration (R) were observed, respectively, in the experimental group and the control group at the beginning and the end of the third day. Time needed for expectoration and length of hospital stay in the two groups were observed. Results It was shown that PaO_2, PaCO_2, SaO_2 , HR, R were significantly improved at the end of the third day when compared with those at the beginning in both groups(P

Condition optimization for immobilization of Fungal laccase with Nylon Net and glutaraldehyde and the nature of the immobilized enzyme were studied. The optimum conditions of the immobilization are: Nylon Net is crosslinked with 5% glutaraldehyde 15mL for 6 hours; the 30U laccase is added for immobilization for 8 hours. On this case, the recovery of enzyme activity was 50.3%. Compared with free enzyme, the thermal stability of immobilized enzyme was improved evidently but the optimal pH decreased slightly. 52% enzyme activity of immobilized laccase was hold after 8 cycles treatment with low concentration pulp wastewater.

OBJECTIVETo find out the epidemiology of bacteria infection after orthotopic liver transplantation (OLT).

METHODPostoperative bacteria infection of 451 OLT cases were retrospectively analyzed.

RESULTBacteria infection were detected in 239 OLT cases, and the infection rate was 52.9%. Sum up to 304 bacilli lines were separated from all above cases. Among them, the detectable Gram-positive bacilli (G(+)) accounted for 59.9% (182/304), while Gram-negative bacilli (G(-)) accounted for 40.2% (122/304). The impressionable organ were respiratory tract and bile duct, which occupying 81.5% (248/304) and 15.1% (46/304) among all infective cases respectively. The main infected strain were G(+) bacteria in respiratory tract, account for 65.3%; while G(-) bacteria were mainly in bile duct, account for 60.9%. There was significant difference between each other (P = 0.018).

CONCLUSIONSThe bacteria infection rate was high after OLT, and the main infected strain was the G(+) bacteria. Most fo them were the opportunistic pathogenic bacteria and the antibiotic multi-resistant bacteria. The bacteria category was significantly related to the infected tissue, according to which we could adopt corresponding antibacterial approach.

OBJECTIVESTo investigate the diagnosis and treatment of cytomegalovirus (CMV) pneumonia after liver transplantation.

METHODSFive cases of CMV pneumonia after liver transplantation were analyzed retrospectively. CMV pneumonia was diagnosed according to its clinical manifestation, chest X-ray, and etiologic test. All 5 patients received comprehensive therapy based on anti-virus treatment and immunologic adjustment.

RESULTSThe clinical manifestation of CMV pneumonia after liver transplantation was nonspecific. Its main symptoms included fever, cough, dyspnea, tachycardia, fatigue, hypoxemia and neutropenia. The chest X-ray showed interstitial pneumonia. Sera CMV antigens or antibodies could be detected in the patients. Four patients were cured and 1 patient died.

CONCLUSIONSThe clinical manifestation of CMV pneumonia was nonspecific. CMV pneumonia could be diagnosed according to its manifestations, chest X-ray and etiologic test. The comprehensive therapy based on anti-virus treatment and immunologic adjustment was effective for the disease.
