Objective To study the effect of Xinji Huoliyin on the apoptosis of myocardial cell and apoptosis-related gene expression of experimental dilated cardiomyopathy rats, and explore its mechanism. Methods Sixty animals were randomly divided into 6 groups. Dilated cardiomyopathy model was made by injecting adriamycin. Experimental rats were given Xinji Huoliyin and Huangqi Shengmaiyin respectively. The genic expression of p53 and Fas was tested by S-P immunohistochemistry technique after 4 weeks. Results The apoptosis rate of myocardial cell of model group was higher than that of normal group (P

Objective:To explore the role of osteopotin in lupus nephritis (LN).Methods:Sera osteopotin( OPN )levels were measured by enzyme linked immunosorbent assay in 90 patients with systemic lupus erythematosus (SLE),15 non-SLE patients with renal impairment,and 30 healthy volunteers.OPN mRNA expression in peripheral blood mononuclear cells (PBMCs) was also investigated with reverse transcription-polymerase chain reaction semi-quantitative method.Results:The expression of OPN was significantly higher in active LN groups than in all other groups(P0.05).Conclusion:The expression of PBMCs OPN mRNA is up regulation in active SLE.Meanwhile,its expression levels are correlated with the activity of LN.

Objective To investigate the relationship between body mass index (BMI) and long-term survival in patients with chronic obstructive pulmonary disease (COPD).Methods A retrospective cohort study was conducted in 1124 patients with completed data among 1528 hospitalized patients with COPD.Vital status was ascertained at death registry and civil affairs department.Clinical characteristics were acquired from medical record.Patients were divided into 4 groups according to the quartile of BMI:BMI＜18.9 kg/m2 (group A),BMI from 18.9 kg/m2to 22.7 kg/m2 (group B),BMI from 22.8 kg/m2 to 26.2 kg/m2 (group C),BMI＞26.2 kg/m2 (group D).The differences in survival curves were compared between groups by using log-rank test.The relationship between all-cause mortality and BMI was evaluated by Cox proportional hazards regression model.Results The median BMI of 1124 patients was 22.7 kg/m2 [(18.9-26.2) kg/m2].270 patients (24.0％) had BMI＜18.5 kg/m2.162 patients (14.4％) died during follow-up.There was significant difference in the survival curves in the four groups (x2 =7.97,P＜0.05).Survival rate was highest in group C and lowest in group A.After adjustment for other factors,BMI was an independent risk factor for predicting long-term survival.The survival rate was respectively decreased by 41 ％ and 35 ％ in group C and D as compared with group A.Conclusions Weight loss is comman in COPD patients.BMI is an independent risk factor for predicting long-term survival.BMI is easily acquired and stable,which is especially suitable to evaluate the prognosis of patients with acute exacerbation.

Objective To evaluate the relationship between the expressions CyclinD1 and nm23H1 and the response to neoadjuvant chemotherapy (NACT) in cervical carcinoma. Methods 100 patients with cervical cancer were enrolled in this study. These patient were randomly divided into two groups. The observed group were treated by neoadjuvant chemotherapy followed by radical hyterectomy and lymphonectomy. The other 50 cases were treated by operation as control group. The expression of CyclinD1 and nm23H1 were examined by immunohistochemistry using post-operation specimens. Results The total response rate of neoadjuvant chemotherapy was 75 %( CR+PR). The expression rate of CyclinD1 was 76 % in experimental group, and 54 % in control group(P 0.05). Conclusion The neoadjuvant chemotherapy was helpful for the patients with local advanced stage of cervical carcinoma. CyclinD1 may be one of the path of NACT, but nm23H1 may not related to NACT.

Objective To evaluate the significance of selective salpingography(SSG)and fallopian tube recanalization(FTR)in diagnosis and treatment for obstructive infertility.Methods Totally, 268women with infertility caused by obstruction of the fallopian tube were divided randomly into two groups, one (Group A)with a non-operative hysterosalpingeal system by insertion of co-axial cannula and guiding filament made by COOK Corporation in the US and another(Group B)with a self-prepared hysterosalpingeal system modified based on the apparatus of COOK Corporation, for SSG and FTR.Then, efficacy of SSG and FTR for the infertile women was evaluated by one-year cumulative pregnancy rate and reeanalization rate of the fallopian tube.Resnits One hundred and seventy of 198 fallopian tubes were recanalized in Group A, with a recanalization rate of 85.8%, and 290 of 320 tubes in Group B were recanalized.with a recanalization rate of 90.6%.reaching statistically significant difference.Furthermore, recanalization rate varied with different sites of occlusion of the fallopian tube.Pregnancy rate was 35.3%(36/102)in Group A, significantly higher than that in Group B(47.6%, 79/166).As the same, pregnancy rate varied with different sites of occlusion of the fallopian tube.Conclusion Selective salpingography and fallopian tube recanalization with self-prepared hysterosalpingeal system have dual effects on diagnosis and treatment for tubal infertility of women, which are simpler, safer and more reliable, worth to be clinically applied.

Objective: To study the efficacy and safety of the intrapleural injection of nedaplatin combined with recombinant hu-man endostatin (Endostar) in the treatment of malignant pleural effusion in non-small cell lung cancer (NSCLC) patients. Methods:Seventy patients diagnosed with NSCLC with malignant pleural effusion were treated by intrapleural injection. The subjects were divid-ed into two groups, as follows: 35 cases were injected with nedaplatin and Endostar (the treatment group) and 35 cases were injected with nedaplatin only (the control group). One month after the treatment, the clinical efficacy and toxicity were evaluated. The clinical ef-ficacy, quality of life, and toxic reaction were compared between the two groups. Results: The short-term clinical efficacy rate of the treatment group was 74.28%, whereas that of the control group was 48.57%, and the difference between the two groups was significant (P<0.05). Adverse effects such as nausea vomiting and leukopenia, occurred in both groups, but no significant differences were found between the two groups (P>0.05). Conclusion: The efficacy of the intrapleural injection of recombinant human endostatin combined with nedaplatin is superior to that of cisplatin alone in the treatment of malignant pleural effusion, without increasing chemotherapeutic toxicity.

Objective To investigate the relationship between urine neutrophil gelatinase-associated lipocalin (uNGAL) level and activity and pathological types of lupus nephritis (LN).Methods Thirty cases of biopsy proven LN patients as the initial onset were enrolled into the study.Ten healthy persons were selected as controls.The clinical and pathological data and blood, urine specimen were collected.The uNGAL was measured by enzyme linked immunosorbent assay.The relationship between uNGAL and clinical and pathological features of LN was analyzed.One-way analysis of variance (ANOVA) and Pearson's correlation analysis were used for statistical analysis.Results Nineteen cases were in the LN active group and 11 cases were in the inactive group.The level of plasma NGAL had no significant difference between the active LN group [(64±6) ng/ml] and the inactive LN group [(58±20) ng/ml] and the healthy control group [(57±20) ng/ml] (P＞0.05).The level of urine NGAL in the active LN group [(69±3) ng/ml] and inactive LN group [(66±5) ng/ml] was higher than that in the healthy control group [(64±5) ng/ml, P=0.009, 0.016, respectively].Urine NGAL level in active LN group was higher than that in the inactive group (P=0.012).Urine NGAL level was positively correlated with SLEDAI, R-SLEDAI, GAI, TLAI, AI (r=0.472, 0.521, 0.502, 0.516, 0.597, respectively, P=0.042, 0.036,0.042, 0.021, 0.007, respectively).The urine NGAL concentration after comparing to different pathological conditions were: urine NGAL's level [(69.7±2.4) ng/ml] of type Ⅳ LN was higher than type ⅢN [(65.3±3.2)ng/ml] and type Ⅴ [(64.6±5.0) ng/ml] (P=0.031, 0.028, respectively).Receiver operating characteristic (ROC) indicated that uNGAL was more sensitive(86.7％) and specific (73.3％) for the diagnose of type Ⅳ LN than type Ⅲ or type Ⅴ LN.Conclusion uNGAL is closely related with disease activity and pathological activity in LN.uNGAL enables clinician to assess the activity of LN and could be a sensitive marker for the diagnosis of type Ⅳ adult LN.
