Objective To explore the clinical efficacy and safety of modified Ponticelli regimen in treating patients with idiopathic membranous nephropathy (IMN).Methods A retrospective analysis was performed in 90 patients with IMN (type Ⅰ / Ⅱ,79/11 respectively) diagnosed by clinical data and renal biopsy.The patients were divided into modified Ponticelli group (n =23),steroid plus cyclophosphamide (CTX) (CTX group,n =39) and steroid plus cyclosporine A(CsA) (CsA group,n =28) according to the treatment.Liver function,renal function,serum lipid,proteinuria were recorded before and after treatment.Efficacy and adverse reactions were evaluated in three groups.Results (1) In all three groups,the quantity of proteinuria after treatment for 3 months [(3.33 ± 1.53) g/d,(4.70 ± 2.97) g/d,(3.92 ± 2.57) g/d],6 months [(1.60 ± 1.10) g/d,(2.34 ± 1.61) g/d,(2.25 ± 1.78) g/d] was significantly decreased compared with baseline level[(7.26 ± 2.06) g/d,(7.50 ± 2.55) g/d,(7.54 ± 2.70) g/d;P ＜ 0.05].Serum albumin levels at 3 months [(31.42 ± 3.86) g/d,(30.59 ± 5.79) g/d,(30.90 ± 7.87) g/d],6 months [(36.25 ± 4.20) g/d,(34.70 ± 6.70) g/d,(35.36 ± 8.29) g/d] were significantly increased compared with baseline levels [(24.13 ± 2.61) g/d,(23.98 ± 3.79) g/d,(22.94 ± 4.57) g/d;P ＜ 0.05],whereas serum creatinine at 3 and 6 months had no significant changes (P ＞ 0.05).(2) After treatment for 3 months,partial remission rates in modified Ponticelli group,CTX group and CsA group were 39.1％,35.9％,35.7％ respectively and complete remission rates were 8.7％,5.1％,10.7％,which were not statistically significant in all three groups (P ＞ 0.05).At 6 months,partial remission rates in three groups were 56.5％,41.0％,42.9％ respectively and complete remission rates were 21.7％,20.5％,28.6％,which did not suggested significant difference in all three groups either (P ＞ 0.05).(3) In modified Ponticelli group,steroid diabetes,impaired liver dysfunction,infections and gastrointestinal adverse events occurred in 1,1,2 and 2 patients,respectively.In CTX group,steroid diabetes,infections and gastrointestinal adverse events occurred in 5,8 and 2 patients,respectively.In CsA group,steroid diabetes and infections occurred in 1 and 3 patients,respectively.Conclusion Modified Ponticelli regimen to treat patients with IMN has a trend of better outcome than classic CTX regimen.The efficacy is not inferior to CsA regimen with fewer side effects.

Objective To observe plasma resistin levels in patients with essential hypertension (HT) of Xinjiang Kazakans and Han nationalities, and explore its association with insulin resistance (IR), blood glucose, blood lipids, blood pressure and obesity. Methods Total 127 Kazakan cases and 131 Han cases were selected as the subjects. According to their blood pressure, they were divided into HT group of Kazakans, control group of Kazakans, HT group of Hans and control group of Hans. Blood pressure, height, weight, waist circum-ference (WC) and hip were measured. Plasma resistin, fasting insulin(FINS), fasting plasma glucose (FPG), total cholesterol (TC), tri-glyceride (TG), high-density lipoprotein cholesterol ( HDL-C), low-density lipoprotein cholesterol ( LDL-C), apoprotein-A1( Apo-A1)and apoprotein-B(Apo-B) were determined. Body mass index (BMI), waist-hip ratio ( WHR), body fat percentage ( BF% )and homeostasis model assessment of insulin resistance index ( HOMA-IR) were calculated. Results Plasma resistin levels in the HT groups of Kazakans and Hans were significantly higher than those in their control groups ( P<0.01 ). There were no significant difference in the comparison of plasma resistin levels in HT groups or control groups between Kazakans and Hans ( P>0.05). Plasma resistin was posi-tively and significandy correlated with age, systolic blood pressure (SBP), WC, BMI, WHR, BF%, FlaG, FINS, HOMA-IR, TG in HT groups of Kazakans and Hans ( HT group of Kazakans, r=0.492,0.296,0.281,0.648,0.263,0.515,0.742,0.759,0.797,0.595; HT group of Hans, r=0.417,0.275,0.391,0.483,0.278,0.318,0.453,0.560,0.641,0.310; P<0.05). After the influential factors such as age, blood glucose, blood lipids and obesity were adjusted, plasma resistin level in four groups were still positively and significantly corre-lated with FINS and HOMA-IR ( HT group of Kazakans, r=0.432,0.410 ; control group of Kazakans, r=0.327,0.305 ; HT group of Hans, r=0.426,0.425 ; control group of Hans, r=0.377,0.392 ; P<0.05), but not correlated with SBP or DBP( P>0.05 ). HOMA-IR, FPG and BMI were independent factors for plasma resistin level in HT group of Kazakans, while HOMA-IR, FlaG and BF% were inde-pendent factors for plasma resistin level in HT group of Hans. Conclusion Plasma resistin level was increased in patients with HT of Kaza-karts and Hans. Close correlations between resistin and obesity, blood glucose and IR were found, and there may be indirect correlation be-tween resistin and blood pressure.

Objective To investigate the role of nuclear factor-kappa B (NF-κB)signaling pathway in propofol-induced suppression of up-regulation of inducible nitric oxide synthase (iNOS) gene expression in LPSstimulated RAW264.7 cells.Methods RAW264.7 cells were purchased from cell bank of Chinese Academy of Sciences and cultured in DMEM culture medium containing 10％ fetal bovine serum.The cells were seeded in 6 cm diameter dishes (3 ml/dish) or in 6-well plates (2 ml/well) with a density of 5 × 105/ml and randomly divided into 3 groups ( n =18): normal control group (group C),group LPS (group L)and group LPS + propofol (group LP).The cells were incubated with LPS 1 μg/ml in groups L and LP.Propofol 50μmol/L was added to the culture medium at 2 h before LPS in group LP.Cells were harvested at 30 min after being stimulated with LPS.Phosphorylation of IκB kinase(p-IKK) and NF-κB activity were detected by Western blot.The expression of iNOS mRNA was determined after 6 h exposure of the cells to LPS.Results LPS significantly up-regulated the expression of p-IKK and iNOS mRNA and increased NF-κB activity in group L as compared with group C.Propofol pretreatment significantly attenuated the effects of LPS on p-IKK,iNOS mRNA expression and NF-κB activity.Conclusion NF-κB signaling pathway is involved in the propofol-induced suppression of up-regulation of iNOS mRNA expression in LPS-stimulated RAW264.7 cells.

Objective To evaluate the efficacy of long-pulsed tunable Nd: YAG laser on capillary hemangioma and to analyse its influencial factors. Methods A retrospective review was conducted on 124 patients with 135 vascular lesions treated with long-pulsed tunable Nd:YAG laser from February, 2007 to January, 2008. Working parameters, including spot size (3-5 mm), pulse duration (10-30 ms) and fluence (120-200 J/cm2) were determined based on the size, color and depth of lesions and adjusted according to the immediate reaction of lesions. The interval of two treatments was 1 month. Results Of the 135 lesions, 100 experienced a more than 95% subsidence, 22 achieved 60%-94% subsidence, 11 got 30% -59% subsidence, and 2 reached less than 30% subsidence. The cure rate and effective rate were 74.07% and 90.37% respectively. Smaller lesions showed a better response to the treatment than larger ones (P<0.0001), whereas the sites and depth of lesions had no effect on the efficacy (both P>0.05). Atrophy scar occurred in 4 (2.96%) lesions, and blisters in 12 (8.89%) lesions after the treatment. No purpura or pigmentary changes occurred. Conclusion The long-pulsed tunable Nd:YAG laser is an effective treatmnt for capillary hemangioma with fast action and few side reactions.

To identify the cause of an outbreak of acute hemorrhagic conjunctivitis (AHC) in Jiangxi (China) in 2010, 20 eye conjunctival swabs were first collected from AHC patients. Then, viruses were isola- ted and tested for human enterovirus 70, coxsackievirus A24 variant (CV-A24v) and adenovirus using the polymerase chain reaction. All CV-A24v isolates underwent sequencing of 3C and VP1 coding regions. Then, a phylogenetic tree was constructed for Jiangxi CV-A24v and worldwide CV-A24v based on,3C and VP1 regions, respectively. Ten out of 20 specimens were positive for CV-A24v, implying that the outbreak was caused by CV-A24v. The phylogenetic tree based on the 3C region showed that Jiangxi CV- A24v belonged to cluster 5 in genotype IV (GIV-C5) with strains isolated throughout the world after 2010, and were divided further into A and B lineages. Phylogenetic analyses of the VP1 region showed that all of the worldwide CV-A24v strains isolated after 2000 could be divided into five groups (1-5). Jiangxi CV-A24v was classified into group 5 and also divided further into A and B lineages upon analyses of the 3C region. These data suggested that CV-A24v causing AHC outbreaks in China in 2010 belonged to GIV-C3 and GIV-C5. At least two transmission lineages were circulated in Jiangxi in 2010. The classification of CV-A24v isolated after 2010 worldwide using the phylogenetic tree based on the VP1 region was almost consistent with that based on the 3C region and also had significant chronological clustering.

Objective To explore the clinical efficacy and indications of kyphoplasty with movement and secondary en?largement of balloon for the compression fracture of vertebral body with ruptured posterior wall. Methods A retrospective analy?sis was carried out on the data of 29 patients (10 males, 19 females;age range:55-86 years old;mean age:71 years old;29 verte?bral bodies in total) who suffered from compression fracture of the thoracolumbar spine and below, and underwent kyphoplasty through the movement and secondary enlargement of balloon within the vertebral body and were followed up from January 2011 to November 2014. These patients had backache, accompanied by lowered support, limitation of movement, no symptom of nervous lesion on both lower extremities and no past history of balloon kyphoplasty. All fractured vertebral bodies were at T 11 or below, in?cluding 1 case at T11, 4 cases T12, 11 cases L1, 9 cases L2 and 4 cases L3. The causes of injury included fall (19 cases), car accident (8 cases) and unknown reasons (2 cases). All patients underwent kyphoplasty with the movement and secondary enlargement of bal?loon within the vertebral body. Photos were taken immediately after the surgery, at 1 month, 3 months, 6 months and 12 months, and these patients were assessed and analyzed in terms of vertebral height, Cobb angle, visual analogue score (VAS) and Oswestry disability index (ODI). Results The operation time (including the formation and solidification of bone cement) of 29 patients was 40 to 65 min and the mean time was 55 ± 7 min;the blood loss during operation was 2 to 15 ml and the mean blood loss was 5 ± 2 ml;the injected volume of bone cement was 2.5-7.5 ml and the mean volume was 5.5±0.5 ml. Post?operative pain was relieved and ambulation was performed under the protection of lumbar orthosis brace. Statstical analysis was conducted on VAS, ODI, vertebral height and Cobb angle before operation and at 1 month, 3 months, 6 months and 12 months after operation, showing statistically significant differences. X ray examination found that there was no alternation or displacement of bone cement location, and no change in vertebral morphology, the vertebral height and cobb angle remained the post?operative status, and posterior wall rupture of the vertebral body was recovered well. CT revealed that the morphology of bone cement was irregular and closely integrated with bone substance, and no cavity or fissure was seen. Conclusion Kyphoplasty with movement and secondary enlargement of bal?loon within the vertebral body has a good, definite clinical efficacy in treating compression vertebral fracture with incomplete pos?terior wall of the vertebral body without obvious displacement of fractured bone and symptom of nervous lesion on both lower ex?tremities. This surgery is easy to operate, and has an immediate analgesic effect, which could recover vertebral height as well as re?duce kyphosis deformity and improve patient’s prognosis.

Objective To investigate the mechanism of Qinggan-Huoxue recipe in the treatment of alcoholic liver disease by observing its function on alcoholic liver disease rat fibroblast growth factor -21 (FGF21). Methods The rats were randomly divided into the blank group (n=10), the carbon tetrachloride group (n=10), the model group (n=11), the Qinggan-Huoxue recipe group (n=10), the Qinggan recipe group (n=9) and the Huoxue recipe group (n=10). Except for the blank group and the carbon tetrachloride group, the other rats were given 10 ml/kg alcohol, corn oil and pyrazole mixture (4.5 ml: 2 ml: 25 mg), once a day, 0.3 ml/kg carbon tetrachloride olive oil solution (carbon tetrachloride: olive oil =1: 3) intraperitoneally, and twice a week for 12 weeks to prepare the alcoholic liver disease model. In the ninth week, the Qinggan-Huoxue recipe group was treated with 4.75 g/kg of Qinggan-Huoxue recipe, the Qinggan recipe group was treated with 1.5 g/kg of Qinggan recipe, and the Huoxue recipe group was treated with 3.25 g/kg of Huoxue recipe, once a day, and 28 d for continuous administration. The pathological changes of liver tissue were observed by HE staining and Masson staining. The serum levels of AST and ALT were detected in rats. The changes of FGF21 protein and mRNA expression were detected by immunohistochemistry, Western blotting and fluorescence quantitative PCR. Results Compared with the model group, the liver weight and liver body ratio in the Qinggan recipe group, Qinggan-Huoxue recipe group and Huoxue recipe group were significantly lower (P<0.01). Compared with the model group, the serum ALT (41.95 ± 26.78 U/L, 46.63 ± 21.00 U/L, 37.57 ± 27.85 U/L vs. 138.34 ± 43.35 U/L), AST (102.74 ± 23.55 U/L, 111.50 ± 21.26 U/L, 83.72 ± 37.57 U/L vs. 257.41 ± 162.31 U/L) in the Qinggan recipe group, Qinggan-Huoxue recipe group and Huoxue recipe group significantly decreased (P<0.01 or P<0.05). Compared with the model group, the expression of FGF21 protein (1.19 ± 0.07, 1.24 ± 0.12 vs. 0.92 ± 0.04) in Qinggan recipe group and Qinggan-Huoxue recipe group significantly increased (P<0.05), and the expression of FGF21 mRNA (1.25 ± 0.08 vs. 0.95 ± 0.05) in Qinggan-Huoxue recipe group significantly increased (P<0.05). Conclusions FGF21 plays an important role in the alcoholic liver disease. During the process of liver injury, FGF21 increases continuously. Qinggan-Huoxue recipe can improve the content of FGF21 in the treatment of alcoholic liver disease.
