Chronic kidney disease has become a global public health problem, and a new pandemic, which seriously endanger people's health and life. With the gradual increase in kidney disease treatment of traditional Chinese medicine, western medicine doctors to rational use of Chinese patent medicine is also worthy of attention and discussion. In this research, we discussed the reliability of traditional Chinese medicine in chronic renal failure with practicability, to the analysis of the current status of Chinese patent medicine in General hospital, and summarizes the effect of traditional Chinese medicine in the treatment of renal diseases and analyzed the disadvantages. Finally, from the clinical research, we concluded that the reasonable application of traditional Chinese medicine in chronic renal failure has a long way to go and we need to make unremitting efforts.

A study on the ideal method for cryopreserving human fetal islet tissues was carried out. The viability and the secretory function of fetal islets cryopreserved with 1.0,1.5,and 2.0 mol/L DMSO and with balancing for 30 and 60 minutes under room temperature and 4℃ as well as the influence of different cooling rates were compared. The results of the study showed that the viability of islets cryopreserved with slow cooling rate at 0.3℃/min, was the best and the insulin content of the media and the amount of insulin secretion of the insulin releasing test were significantly higher than those of the control group.In addition,morphologic examination with HE and immunocytochemical staining showed that the morphology of the islets cryopreserved with 1.5 mol/L DMSO,balancing under 4℃ for 60 minutes and slow cooling rate was much better,i.e.the acinar cells appeared to be degenerated and necrosed,clusters of islets with insulin-positive cells and the ductule-like cells were clearly visible.

A cross-sectional study of 92 women with polycystic ovary syndrome(PCOS) was performed.The patients were composed of 4 groups according to the Rotterdam criteria and were also divided into 2 groups according to body mass index and divided into 2 groups according to insulin-releasing test.Anthropometric measurements were recorded,and hormonal profile was assessed by measuring FSH,LH,prolactin,and testosterone.The metabolic profile was investigated by measuring glucose and insulin level during oral glucose tolerance test (OGTT),then calculating the homeostasis model assessment (HOMA).Serum lipid levels,including total cholesterol,triglycerides,high-density lipoprotein-cholesterol,and low-density lipoprotein-cholesterol were determirned.The result suggests that the classification according to the revised 2003 Rotterdam consensus on diagnosis does not reflect dyslipidemia in PCOS.Dyslipidemia in hyperinsulinemic group and obesity group were more severe than that in non-hyperinsulinemic group and non-obese group ; this finding needs our attention in early treatment and prevention of late complications of PCOS.

Objective To investigate the antibiotic resistance of extended-spectrum β-lactamases (ESBLs)-producing bacteria,and the risk factors for patients with hospital-acquired lower respiratory tract infections caused by these bacteria.Methods The clinical data of 80 cases of hospital-acquired lower respiratory tract infections caused by ESBLs + bacteria in the People's Hospital of Qingtian in Zhejiang Province from July 2008 to December 2011 were collected; and 160 cases of nosocomial infection caused by ESBLs- bacteria were randomly selected as controls.Univariate analysis and multivariate logistic regression were used to analyze the risk factors for ESBLs + bacteria infection.The resistance of sixteen antibiotics was detected by K-B method.Results Univariate analysis revealed that the risk factors for nosocomial lower respirator tract infection caused by ESBLs+ bacteria were hospitalization ≥ 10 d,readmission to hospital,oxygen inhalation,invasive operations,using antacid ＞ 7 d,using glucocorticoids ＞ 7 d,using immunosuppressant ＞ 7 d,using third-generation cephalosporins,using fluoroquinolone antibacterials,and the combined use of antibiotics≥3 d.Multivariate logistic regression analysis identified five independent risk faetors:oxygen inhalation (OR =8.613,95％ CI:1.870-39.659),invasive operations (OR =5.900,95％CI:1.885-18.467),using third-generation cephalosporins (OR =7.465,95％ CI:2.364-23.578),using fluoroquinolone antibacterials (OR =4.481,95％ CI:1.197-16.781) and combined use of antibiotics≥3 d (OR =5.346,95％ CI:1.717-16.643).ESBLs + Escherichia coli and Klebsiella pneumoniae strains were sensitive to imipenem,meropenem,cefoperazone /sulbactam and piperacillin/tazobactam (with the resistance rates lower than 30.00％),but were highly resistant to most β-lactam,aminoglycoside,fluoroquinolone and sulfonamide antibacterials.Conclusion ESBLs + isolates were highly resistant to most antibacterials,and hospital-acquired lower respiratory tract infections with ESBLs+ bacteria are mainly related with invasive operations and the use of antibiotics.

Nowadays, there are more and more researches on characters and applications of polycaprolactone (PCL). This paper reviews the researches of polycaprolactone, including its synthesis, physical and chemical properties, biodegradation, absorption properties, and its applications in clinical use and drug delivery systems. PCL can be from open ring polymerizaion. It is a kind of semi-crystalline polymer, and has good flexibility. The degradation reaction of PCL is hydrolysis. PCL is not cumulated in the body, and can be totally excreted. It can be used as suture, material for fixation of bone fracture, vector of drug, etc. PCL is widely used in medical area because of its safety, low toxicity, biodegradability.

Objective To explore the effects of Chinese herbal compound Tangbikang on the expressions of p38 MAPK of sciatic nerve and plasma TNF-α in diabetic rats. Methods Ten of the sixty male SD rats were selected randomly as normal group, and the rest were fed with high-fat diet and low-dosage STZ was used to induce type Ⅱdiabetic rat models. Model rats were randomly divided into model group, mecobalamine group and Tangbikang low-, medium-, and high-dosage groups, 10 rats in each group. Each medication group was intervened with relevant medicine. Rat unilaterals sciatic nerves were taken after 16 weeks. The content of TNF-α in plasma was determined by radioimmunoassay. Western blot method was used to detect the expressions of p38 and p-p38 MAPK protein of sciatic nerve. Results Compared with normal group, the expressions of p38 and p-p38 protein and content of TNF-αin model group significantly increase (P<0.05, P<0.01). Compared with the model group, the expressions of p-p38 protein and the content of TNF-α significantly decreased after medicine intervention in different doses Tangbikang groups and mecobalamin group (P<0.05, P<0.01). The expression of p38 protein in Tangbikang high-dose group significantly decreased (P<0.05), with statistical significance (P<0.05). Conclusion Tangbikang can reduce the expression of p38 and p-p38 MAPK protein of the rat sciatic nerve, and reduce the content of TNF-α protein in rat plasma, which may be one of the effective targets of neuroprotection and abirritation of diabetic peripheral neuropathy.
