Objective To investigate the clinical features of osteonecrosis of the knee (ONK) in patients with systemic lupus erythematosus (SLE).Methods A retrospective chart review was conducted to identify patients of SLE with ONK.The clinical characteristics of these patients were analyzed.Results Between 2008 and 2013,eighty-one patients with SLE were analyzed in the 210th Hospital of People's Liberation Army.Eleven of these patients were diagnosed as ONK.All of these ONK patients were female.The age of onset ranged from 19-57 (36±13) years.The disease duration ranged from 4.5-31.0 (13±6) years.The local clinical symptom included knee swelling with pain in 5 cases,only pain with no swelling in 1 patient,no symptoms in 5 patients.All patients were with aseptic necrosis of the femoral head.For laboratory examination,7 patients had elevated triglyceride lipids in blood.Three of 7 patients accompanied with cholesterol level increased.Total cumulative dosage of oral corticosteroids was (66 824±27 328) mg.Conclusion ONK in patients of SLE is common and the majority of them have impaired renal function and elevated blood lipids,as well as long-term glucocortico-steroid therapy.

Objective To investigate the effects of diabetic duration on liver fat content (LFC) in patients with type 2 diabetes,and to explore its relationship with the outcome of liver disease.Methods A total of 435hospitalized patients with type 2 diabetes were recruited.The history data,results of laboratory tests,and hepatic 1 H-MRS were collected,and nonalcoholic fatty liver disease (NAFLD) fibrosis score (NFS) was calculated.Results The prevalence of NAFLD in newly-diagnosed type 2 diabetes mellitus (NT2DM) group was higher than that in predousb-diagnosed type 2 diabetes mellitus (PT2DM) group (92.7％ vs 82.2％,P＜0.05),with higher LFC [(27.97 ± 16.88 vs 19.44± 15.54) ％,P＜0.01].The LFC was reduced with prolonged duration of diabetes.Partial correlation analysis showed that LFC was negatively correlated with duration of diabetes (rs =-0.233,P＜0.01) after adjustment for gender,age,body mass index (BMI),oral anti-diabetic drugs,lipid-lowering drugs,and insulin treatment.Multiple linear regression analysis showed that LFC was positively correlated with BMI,albumin,and alanine aminotransferase while negatively correlated with duration of diabetes.The proportion of patients without advanced fibrosis (NFS＜-1.455) was significantly higher in NT2DM group than that in PT2DM group (26.3％ vs 15.5％,P＜0.05),and the proportion of PT2DM in patients with advanced fibrosis (NFS＞0.676) was significantly higher than that of NT2DM (79.2％ vs 20.8％,P＜0.05).NFS was positively correlated with the duration of diabetes (rs =0.236,P＜0.01).The liver fat content in patients with advanced liver fibrosis decreased significantly,and the LFC was negatively correlated with NFS (rs =-0.164,P＜0.01).Conclusions The duration of diabetes is an independent influencing factor of LFC.With the extension of the duration of diabetes,the decreased LFC in type 2diabetic patients with NAFLD is related to the development of advanced fibrosis.The decrease in LFC in type 2diabetic patient is associated with poor outcome of NAFLD.

Objective To analyze the association of fat content,enzymes,and fibrosis in liver with iron overload in patients with type 2 diabetes,and to explore the relationship between iron overload and severity of nonalcoholic fatty liver disease (NAFLD) in these patients.Methods Five hundred and thirty hospitalized patients with type 2 diabetes and 18 patients with abnormal glucose metabolism undergoing liver biopsy were recruited.History data,results of laboratory tests,liver ultrasound,hepatic 1 H-MRS were collected and serum ferritin level was determined.Results The serum ferritin level was significantly higher in patients with NAFLD than that without NAFLD [(328.7±252.2 vs 239.9 ± 171.8) μg/L,P＜0.01].Serum ferritin was an independent risk factor for NAFLD (P＜0.05).Multiple linear regression analysis showed that serum ferritin was positively correlated with liver fat content after adjustment for sex,age,and duration of diabetes.The serum ferritin level in NAFLD with elevated liver enzymes was significantly higher than that in simple steatosis [(429.9 ± 287.4 vs 293.4 ± 233.3) μg/L,P＜0.01].Serum ferritin was an independent risk factor for elevated liver enzymes in patients with NAFLD (P ＜0.05).Serum ferritin level in patients with advanced fibrosis was significantly lower than that in patients without advanced fibrosis [(246.8 ± 191.2 vs 382.5 ± 253.7) μg/L,P＜0.01].In 18 patients with NAFLD proven by biopsy,serum ferritin level was slightly higher in NASH group than that in simple steatosis group,but there was no statistically significant difference.Serum ferritin levels were comparable between patients with and without advanced fibrosis.Conclusion The iron overload in type 2 diabetic patients seems to be an independent risk factor for the development of NAFLD and elevated liver enzymes.Iron load in patients with advanced fibrosis is significantly decreased.

Data were gathered from epidemiological survey of Xinjiang Hetian area in 2008 and 2 228 subjects were included.Waist-height ratio (WHtR),body mass index (BMI),Waist-hip ratio (WHpR) were calculated.Kappa test was applied to determine the concordance among different methods.The results showed that according to International Diabetes Federation 2005 diagnostic criteria for metabolic syndrome,it was better to apply WHtR in predicting metabolic syndrome by the receiver operating characteristic (ROC) curve than BMI,abdominal circumference,and WHpR.When the cutoff of WHtR was 0.53,the sensitivity and specificity in diagnosing MS were 91.2％ and 71.8 ％,with its area under ROC curve 0.878.Kappa test showed an intensive concordance between WHtR and waist circumference (WC).The specificity and sensitivity of diagnosing MS would be significantly raised by using both WHtR and WC.

Objective To investigate the clinical and pathological characteristics of nephrogenic adenoma. Methods Eleven patients were diagnosed as nephrogenic adenoma including 5 men and 6 women, aged 37-78 years (56 on average). The pathological findings in all cases of nephrogenic adenoma were presented with a review of the literature. Results Eleven cases of nephrogenic adenomas were evaluated, 2 cases were in ureter and 9 cases were in the bladder. Eight of the 9 bladder cases underwent TUR-BT surgery in continuous epidural anesthesia, 1 case underwent partial cystectomy with general anesthesia. A right ureteroscopy and left ureterolithotomy were performed respectively in continuous epidural anesthesia for the 2 cases in ureter. The final diagnosis was based on histopathological findings. For all of cases, 8 cases were diagnosed as nephrogenic adenomas, 2 cases as atypical nephrogenic adenoma and 1 case as nephrogenic adenoma with malignant transformation. The microscopic appearance of nephrogenic adenoma demonstrated that morphology closely resembled aberrant tubules of the kidney. In addition, atypical nephrogenic adenomas appeared as the presence of cytologic atypia, including nuclear enlargement, nuclear hyperchromasia and prominent nucleoli. The morphologic changes of nephrogenic adenomas with malignant transformation were that tumor cells retained the basic structural characteristics of typical nephrogenic adenomas, and the similar morphological cells lost adhesion ability among cells and presented diffuse solid growth in the surrounding area.Intravesical perfusion was further performed for treating the patients with atypical nephrogenic adenomas or nephrogenic adenomas with malignant transformation. The mean patient follow up was 46 months (range, 24- 104 months), and there was only 1 case of recurrence. Conclusions Nephrogenic adenoma is an uncommon benign lesion of the urinary tract. The symptoms and cystoscopic manifestations are not unique. We reported one patient of nephrogenic adenomas with malignant transformation and provided some evidence for malignant alteration in morphology and invasive behavior. All patients underwent local excision of the lesions. Intravesical perfusion was further performed for treating the patients of atypical nephrogenic adenomas or nephrogenic adenomas with malignant transformation. Whether it is nephrogenic adenoma or atypical nephrogenic adenoma, long-term follow-up after treatment is necessary.

BACKGROUND:Shengji Yuhong col agen showed good curative effect of promoting angiogenesis and tissue healing compared with Shengji Yuhong Gao and col agen alone or gelatin alone.
OBJECTIVE:To explore the curative effect and mechanism of subcutaneous implantation of Shengji Yuhong col agen in rabbits in promoting angiogenesis and repair.
METHODS:Shengji Yuhong col agen as the experimental group and collagen as the control group was implanted inside the rabbit subcutaneous pockets of the back of New Zealand rabbits. The implanted samples and
surrounding tissues were obtained at 3, 7, 14, 28 and 56 days fol owing surgery. Pathological sections were made and the repair of surrounding tissue was observed. Hemoglobin levels in col agen were measured.
Immunofluorescence and CD34 dyeing marking method were utilized to observe capil ary angiogenesis. Western blot assay was employed to examine vascular endothelial growth factor and angiogenin-1 expression.
Immunohistochemistry was used to observe the secretion of typeⅠ and Ⅲ col agen on the surrounding tissues.
RESULTS AND CONCLUSION:The experimental group showed increased subcutaneous vascularization. There were reduced inflammatory exudation, granulation tissue hyperplasia, and mature fiber connective tissue at 28 days.
Angiogenesis and hemoglobin contents were greater in the experimental group than in the control group (P<0.05 or P<0.01). At 3 and 7 days fol owing surgery, vascular endothelial growth factor and angiogenin-1 expression was greater in the experimental group than that in the control group (P<0.05 or P<0.01). The secretion of type Ⅰ col agen was
identical between the experimental and control groups. However, the secretion of type Ⅲ col agen was higher in the experimental group than in the control group at 28 and 56 days (P<0.05), and the proportion of type Ⅰ and Ⅲ
col agen was lower in the experimental group than in the control group at 28 and 56 days (P<0.01). These suggested that Shengji Yuhong col agen can significantly promote angiogenesis in the surrounding tissues with the possible
mechanisms of adjusting the protein expression of vascular endothelial growth factor and angiogenin-1. At the same time, it has the function of regulating col agen formation with better ratio of typeⅠ and type Ⅲ col agen to acquire higher
quality of wound healing with reduced scar formation.

This article was aimed to explore the effect ofSan-Huang (SH) decoction on improving chemosensitivity of MCF-7 cells to epirubicin and inhibition of Aurora kinase A, in order to discuss its underlying mechanism. The inhibition of MCF-7 cells proliferation on breast cancer by SH decoction was determined by CCK-8 assay. RT-PCR and western blot were used to detect the Aurora A, p53 mRNA and protein expression level of MCF-7 cells by SH decoction. The siRNA silenced Aurora A of MCF-7 cells. CCK-8 assay was used to detect the inhibition of MCF-7 cells proliferation. CCK-8 assay and AnnexinV-FITC/PI staining were used to detect the inhibition rate and apoptosis rate of MCF-7 cells treated by the combination of SH decoction and epirubicin. Western blot analysis was used to detect the expression of apoptosis-related proteins. The results showed that SH decoction inhibited the proliferation of MCF-7 cells in a dose-dependent manner (P< 0.05). The effect of 48 h medication was better than 24 h (P < 0.05). There was no statistical difference with medication for 72 h (P > 0.05). SH decoction can regulate the Aurora A, p53 protein and mRNA expression of MCF-7 cells. siRNA silenced Aurora A, which downregulated the inhibition rate of MCF-7 cells by SH decoction for 50.0% (from 49.2% to 24.8%). The combination of SH decoction and epirubicin enhanced the effect of epirubicin on inhibiting the proliferation rate and apoptosis rate of MCF-7 cell, regulated the expression levels of apoptosis-related protein such as c-PARP, c-Caspase 3, Bcl-2, Bax, as well as the protein level of Aurora A. It was concluded that SH decoction can increase the chemosensitivity of MCF-7 cells to epirubicin, which may be related to the inhibition of Aurora Kinase A by SH decoction.

ObjectiveTo observe the hong-huang antioxidant on oxidative stress in patients with breast cancer during chemotherapy, including their related blood indexes, blood rheology changes, and the effects on TCM clinical symptoms and symptoms of stress.MethodsA total of 60 cases of breast cancer patients during chemotherapy from Jiangsu Province Hospital of TCM was randomly divided into treatment group and control group, 30 cases in each group. On the basis of conventional therapy, patients in treatment group were given hong-huang antioxidant (100 mL per bag) from the 1st day to the 14th day of chemotherapy, 2 bags for each day (morning and evening). Patients in control group were given foundation treatment the same as the treatment group. Patients in the two groups had their serum NO, the content of SOD, and blood rheology tested on the day before chemotherapy, and the 4th, 7th, 14th days during chemotherapy. Meanwhile, their symptom score and the integral of stress reaction and TCM symptoms were also assessed. ResultsOn the 4th day, serum NO of treatment group decreased, while SOD content increased,without statistical significance between the two groups (P>0.05). Serum NO on the 7th, 14th days was significantly lower than that in the control group, but the content of SOD was higher than that in the control group, with statistical significance between the two groups (P<0.05). Hemorheology on the 4th day significantly decreased after treatment (P<0.05), and was significantly better than that in the control group (P<0.05); Clinical symptoms and stress symptoms integral in the treatment group were significantly lower than those in the control group on the 4th, 7th, 14th days of chemotherapy, with statistical significance (P<0.05).Conclusion Hong-huang antioxidant can significantly improve the oxidative stress status, serological indexes, related blood rheology indexes, and clinical symptoms in patients with breast cancer.

Objective To evaluate the severity of non-alcoholic fatty liver disease(NAFLD) and progressive liver fibrosis(stage＞2)in hospitalized patients with type 2 diabetes mellitus(T2DM) by using NAFLD fibrosis score (NFS).The risk factors associated with progressive fibrosis were also analyzed.Methods A total of 721 hospitalized patients with T2DM and uhrasound verified NAFLD were involved.The history information and laboratory examinations were collected,NFS was calculated.The low cutoff score (-1.455) of NFS was used to exclude,and high cutoff score (0.676) to further accurately diagnose progressive fibrosis.Results (1) A total of 721 subjects (male/female 371/350) were diagnosed as NAFLD by ultrasound.In those subjects,173 patients were with progressive fibrosis (24.0％),111 patients without progressive fibrosis (15.4％),and 437 patients (60.6％) with NFS ranged from-1.455 to 0.676.(2) Aging,raised body mass index,aspartate amino transferase/alanine aminotransferase (AST/ALT) ratio,lowered albumin,and platelet were risk factors for progressive fibrosis of NAFLD.In addition,NFS was positively correlated with duration of diabetes,waist circumference,SBP,glycated albumin (GA),and GA/HbA1c(all P＜0.01),and negatively with red blood cell count,hemoglobin,white blood cell count (WBC),total cholesterol (TC),triglyceride,apolipoprotein-B,ALT,γ-glutamyltranspeptidase (all P＜0.01),AST,low-density lipoprotein cholesterol (all P＜0.05).(3) Logistic stepwise regression analysis showed diabetes duration,waist circunference,and GA were positively correlated with progressive liver fibrosis(OR =1.182,1.076,1.074,all P＜0.01),and negatively with WBC and TC (OR =0.613,0.703,all P＜0.01).Conclusions The detection rate of progressive fibrosis in patients with NAFLD and T2DM was approximately 24.0％ by applying NFS.Only 15.4％ of those subjects could be excluded from progressive fibrosis.It suggests that we should be alert to the risk of liver fibrosis in patients with type 2 diabetes.
