OBJECTIVETo observe the effect of Bushen Huoxue Recipe (BSHXR, a Chinese medicine recipe for Shen reinforcing and blood circulation activating) on the levels of urinary albumin, interleukin-6 (IL-6), transforming growth factor-beta1 (TGF-beta1), and monocyte chemotactic protein-1 (MCP-1) in chronic nephritis patients of Shen-deficiency blood-stasis syndrome.

METHODSForty-five patients were blocking assigned randomly to two groups, fifteen patients in the control group and thirty in the treatment group. All orally took Monopril 10 mg, once daily. But BSHXR was given additionally to patients in the treatment group after decocting,one dose per day (taken in two times). The treatment course for both groups was eight weeks. Besides, a normal control group consisting of six healthy subjects from health examination of Shuguang Hospital was set up. The 24-h urinary albumin and contents of TGF-beta1, IL-6 and MCP-1 in urine of all subjects were observed.

RESULTSCompared with before treatment the 24-h urinary albumin was obviously reduced in the treatment group, showing significant difference (P<0.01). The urinary 24-h albumin decreased in the control group, with statistical significance (P<0.05). Statistical difference existed between the treatment group and the control group after treatment (P<0.01). Compared with before treatment, urinary levels of IL-6, TGF-beta1, and MCP-1 were all down-regulated in the treatment group and the control group after treatment (P<0.01), and the decreasing of IL-6 and TGF-beta1, levels was more significant in the treatment group statistically (P<0.05).

CONCLUSIONSBSHXR could attenuate the albuminuria in patients of chronic nephritis. Its mechanism might be possibly correlated with its down-regulation of IL-6, TGF-beta1, and MCP-1 levels.

Objective To analyze risk factors for the perioperative complications and death following hip fracture in the elderly. Methods The present study included 1352 elderly patients (≥65 years) who had received hip fracture surgery from January 2010 to June 2015 in Huadong hospital affiliated to Fudan University. Their clinical data were analyzed to determine risk factors for perioperative complications and death. Results Factors significantly affecting the perioperative complications included gender, preoperative serum albumin, ASA grade (≥Ⅲ), cardiac functional grade (≥Ⅲ), respiratory system disease and blood transfusion. Factors significantly affecting the death included preoperative serum albumin, ASA grade (≥Ⅲ), cardiac functional grade (≥Ⅲ) and blood transfusion. Multivariate Logistic regression analysis revealed that the independent risk factors for perioperative complications included gender (B=-0.686, P=0.019), preoperative serum albumin (B=-0.808, P=0.006), cardiac functional grade (≥Ⅲ, B=1.181, P=0.004), blood transfusion (B=0.890, P=0.004) and respiratory system disease (B=3.118, P=0.000);while the independent risk factors for death included preoperative serum albumin (B=-2.516, P=0.000) and blood transfusion (B=1.396, P=0.010). Conclusions In elderly patients undergoing hip fracture surgery, the independent risk factors for perioperative complications included gender, preoperative serum albumin, cardiac functional grade, blood transfusion and respiratory system disease, while the independent risk factors for death included preoperative serum albumin and blood transfusion. Perioperative risk assessment and prevention are the keys of better prognosis.

Objective To investigate the suppression effects of Tripotolide (TL) on the pancreatic cancer xenograft models and angiogenesis. Methods The growth suppression effect of TL on SW1990 was determined using cell count kit (CCK-8), apoptotic cells induced by TL were examined by morphology and terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay. The inhibitory effects of TL on the growth of tumor xenografts and tumor microvascular density (MVD) were investigated. ResultsTL inhibited the growth and proliferation of SW1990 cells in a concentration-dependent and time-dependent manner. The inhibition ratios of cells treated at 160 mg/ml TL for 24 h was 50. 6%, the apoptotic rate increased from 9.6% in the control group to 45.1% (P <0.01 ). The inhibition rate of cancer xenograft growth was 89.9% when TL was intratumorally injected at the dose of 0.5 mg/kg. The expression of VEGF in tumor tissue decreased while MVD also decreased from 36.25±8.64 to 9.87±3.34 (P <0.01 ). ConclusionsTL induced prominent growth inhibition and apoptosis in human pancreatic cancer cell lines. TL.can attenuate the growth of pancreatic caner xenografts through its effect on antiangiogenesis.

ObjectiveTo explore the clinical characteristics of pathological fracture in extremities caused by bone tumors or tumor-like lesions. MethodsFrom August 2002 to December 2010, 139 patients with pathological fractures were entered in the study, including 79 males and 60 females with an average age of 31.1 years. Fractures included tumor-like lesion in 55 cases, benign tumor in 13, giant cell tumor (GCT)in 7, primary malignant tumors in 28, and metastatic tumors in 36. Forces induced to fractures were classified into four grades: spontaneous fracture, functional activity, minor injury, severe injury. Age, fracture location, histological results, fractures forces, prodromes, and misdiagnosis were all observed. Chi-square test were use to compare forces and prodromes within different tumors. ResultsThe highest morbidity rate is 32.4％(45/139) which lies in 11-20 years old. The cites of fractures including femurs in 71 cases, humerus in 36, tibia in 15, fingers in 7, radiuses in 4, fibula in 3, ulnas in 2, and metatarsus in 1. Fracture forces include spontaneous fractures in 29 cases, functional activity in 42, minor injuries in 65, and traumatic injuries in 3. Sixty-seven patients(48.2％) had local prodromes. The prodromes of both malignant tumors and metastatic tumors were more than benign tumors. Twenty cases experienced misdiagnosis with average delay time of 12 weeks. ConclusionMinor injury forces and local prodromes are clinical key features of pathological fractures. Both of them are key points of avoiding misdiagnosis.

OBJECTIVETo compare the pharmacokinetic parameters of pyridostigmine bromide dispersible tablets and common tablets in rabbits.

METHODSTwelve rabbits were given an oral dose (60 mg) of pyridostigmine bromide dispersible tablets or common tablets in a randomized crossover study. The plasma concentration of pyridostigmine bromide was determined by reversed-phase ion pair chromatography. The pharmacokinetic parameters were calculated using DAS2.1.1 software.

RESULTSThe pharmacokinetic parameters showed no significant differences in rabbit plasma between pyridostigmine bromide dispersible tablets and common tablets. The two tablets had a C(max) of 1.83∓0.08 mg·L(-1) and 1.68∓0.03 mg·L(-1), tmax of 2.33∓0.41 h and 2.58∓0.20 h, AUC(0-24) of 15.50∓0.62 mg·h·L(-1) and 15.14∓0.30 mg·h·L(-1), AUC(0-∞) of 15.82∓0.70 mg·h·L(-1) and 15.57∓0.32 mg·h·L(-1), respectively. The relative bioavailability F(0-24) was 102.38% and F(0-∞) was 101.61% for the dispersible tablets.

correlation with cross-sectional area and negative correlation with bucking ratio. The effect of fat mass on hip geometric parameters at the three regions was inconsistent. (3) Fat mass and percentage of body fat ( Fat%) showed negative correlation with cross-sectional area and average cortical thickness and positive correlation with bucking ratio in young group. However, the negative contribution produced by fat mass and Fat% to hip geometric structure became weaker gradually in middle-aged and older groups. ( 4 ) Limb lean mass yielded the largest positive contribution to cross-sectional area and average cortical thickness at all three regions in young group. However, the contribution produced by trunk lean mass became the largest positive contribution to cross-sectional area and average cortical thickness in older group. Conclusions Among all the body composition parameters, hip BMD has showed the most marked correlation with hip geometric structure. Lean mass is ranked the second in the correlation. The impacts of fat mass and lean mass on hip geometry are changing with aging and their different tissue distributions.

Objective To investigate the role of CC chemokine ligand 20 (CCL20) and CC chemokine receptor 6 (CCR6) in the pathogenesis of acute necrotizing pancreatitis (ANP). Methods 48 SD rats were randomly divided into two groups: control group and ANP group. The ANP model was induced by retrograde infusion of 4 % sodium taurocholate into the biliary and pancreatic duct in SD rats. The same amount of saline was injected in the control group. The rats were sacrificed at 1, 3, 6, 12 h, the serum amylase levels and the pathological score of the pancreas were measured. The expressions of CCL20 and CCR6 mRNA and protein in pancreas were detected by immunohistochemistry and semi-quantitative RT-PCR,respectively. Results The levels of serum amylase and the histological score of ANP group were significantly higher than those of control group (P ＜ 0.01 ). The expression of pancreatic CCL20 mRNA and protein was increased in a time-dependant manner ( P ＜ 0.05 ). The expression of pancreatic CCR6 mRNA at 6h was significantly higher than that of control group (0.88 ± 0.05 vs 0. 23 ± 0.09, P ＜ 0.01 ). The expression of pancreatic CCR6 mRNA at 12h was decreased when compared with that of 6h group, but it was still higher than that of control group (0.37 ± 0. 10 vs 0. 15 ± 0.07, P ＜ 0.05 ), the change of CCR6 protein was consistent with that of CCR6 mRNA. Conclusions CCL20 and CCR6 may play an important role in the pathogenesis of ANP.
