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 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 assess the effects of tacrolimus (FKS06) on podocyte in type 2 diabetic model rats and to explore the potential mechanism.Methods The model rats were fed with high fat and high sugar food and combining with a low-dose of streptozotocin (STZ).They were then randomly divided into a diabetic mellitus group (DM group) and a FK506 group.A normal control group (NC group) was also set.The rats in FK506 group were given with 0.5 mg· kg-1· d-1 FK506 for 8 weeks.The biochemical parameters were measured.The changes of renal pathology and ultrastructure of podocyte were observed by the light and electron microscopy.The expression of nephrin and LC3-Ⅱ was determined by immunohistochemistry and Western blotting.Results (1) Compared with those in NC group,KW/BW,systolic blood pressure (SBP),fasting blood glucose (FBG),triglyceride (TG),total cholesterol (TC),urinary albumin excretion rate (UAE) and creatinine clearance rate (Ccr) in DM group were significantly increased (all P < 0.05).And the KW/BW,UAE and Ccr were decreased in FK506 group compared to those in DM group (all P < 0.05),while other parameters had no significant difference (all P > 0.05).(2) Compared with those in NC group,the glomerular volume,mesangial cell proliferation and accumulation of mesangial matrix were increased,and the foot process became disorder and fusion in DM group,while these changes were significantly reduced in FK506 group.(3) Compared with that in NC group,the expression of nephrin and LC3-Ⅱ was decreased in DM group (all P < 0.05),and both of parameters were higher in FK506 group than those in DM group (all P < 0.05).Conclusion FK506 may enhance podocyte autophagy in type 2 diabetic model rats and attenuate podocyte injury.

Objective To investigate the relationship between interleukin (IL)-18 and podocyte injury of lupus nephritis (LN). Methods Sixty cases of biopsy proven LN patients were enrolled into the study. Thirty cases were selected as controls. The clinical and pathological data, blood and urine samples and renal tissues were collected. The Nephrin expression was detected by immunohistochemical method and IL-18 was measured by enzyme linked immunosorbent assay. The relationship between IL-18 and the Nephrin expression, clinical and pathological indicators of LN were analyzed. Results Thirty-eight cases were in active disease and 22 cases were in inactive disease in LN group according to SLE disease activity index (SLEDAI) 2000. One-way ANOVA showed that the level of plasma and urine IL-18 in the LN groups were higher than those in the control group [(200±38) ng/ml, (18±5) ng/ml] (F=110.84, 203.09, P<0.01). Plasma and urine IL-18 level in active LN group [(565 ±128) ng/ml, (200 ±47) ng/ml] was higher than that in the inactive group [(376 ±106) ng/ml, (67 ±22) ng/ml] (P<0.01), the level of IL-18 of type Ⅳ LN was significantly higher than that of typeⅢand type Ⅴ LN (P<0.01). The expression level of Nephrin in LN groups were lower than those in healthy control group (0.28±0.02)(F=136.39, P<0.01). The expression level of Nephrin in active LN group (0.13±0.03) was lower than that in the inactive group (0.18±0.02) (P<0.01), the level of typeⅣLN Nephrin was significantly 01). The Pearson correlation analysis showed that, compared with plasma IL-18, urine IL-18 level in the LN group was not only negatively correlated with the level of Nephrin and serum C3 (r=-0.780, -0.565, P<0.05), but positively correlated with 24 h UP, erythrocyte sedimentation rate (ESR), SLEDAI and GAI (r=0.546, 0.467, 0.599, 0.634, P<0.05). Serum IL-8 level was independent of albumin (ALB), C4, C reactive protein (CRP) and CI (P>0.05), and was negatively correlated with estimated glomerular filtration rate (eGFR) (r=-0.562, P<0.05). It was positively correlated with serum creatinin, blood urea nitrogen, AI, TLAI and inflammatory cell infiltration (r=0.529, 0.482, 0.665, 0.690, 0.671, P<0.05). Conclusion IL-18 has a very close relationship with podocyte injury in patients with LN, and the uIL-18 can be a potential non-invasive detection method to monitor podocyte injury in LN patients.

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.
