Objective To investigate the relationship between plasma neuropeptide Y(NPY) and asphyxia in newborns. Methods Thirty-seven patients with neonatal asphyxia (asphyxia group) and 33 healthy pregnant women(control group )in their third trimester were chosen. The concentrations of plasma NPY were measured by radioimmunoassay. Results The levels of NPY in umbilical artery plasma was (187.47? 46.63) ng/L in asphyxia group,and (115.33?29.42) ng/L in control group. There were significant difference between them ( P 0.05). Conclusions The neonatal asphyxia was associated with NPY. NPY might play an important role in the pathophysiological changes in neonatal asphyxia.

To evaluate the application of nueroelectrophysiological tests in early diagnosis of sub-clinical neuropathy in diabetes mellitus (DM), The routine nerve conductive velocity (NCV), F-wave and sympathetic skin response (SSR) were detected in 27 patients with diabetes mellitus but without symptoms and signs of lesions of nerve system. Our results showed that 48.1%, 44.4%, 51.9% of the patients were found to have abnormal NCV, F-wave and SSR respectively. The abnormalities were mainly characterized by prolonged latency, reduced velocity and absence of wave-form. There were significant differences between the controls and the DM group (P < 0.05). Both the distal and proximal segments of nerves were affected and the distal lesions took place earlier than proximal ones and the changes in low extremities were more severe than those of upper extremities. F-wave can be used as a sensitive indicator for the early diagnosis of peripheral neuropathy and it can help to detect the subclincial lesions. SSR can be used for the evaluation of functional status of autonomic nerves in DM patients.

OBJECTIVE:To provide reference for promoting the priority use of essential medicines. METHODS:The use amount ratio of essential medicines in 2 third-level grade-A hospitals in Beijing from 2011 to 2013 was statistically investigated. And the literatures related to policies of essential medicines and application were retrieved for in-depth analysis. RESULTS:The use amount ratios of essential medicines in the outpatient and emergency departments in Beijing Hospital of Ministry of Health from 2011 to 2013 were respectively 24.04%,23.10% and 22.76%;and the use amount ratios of essential medicines of inpatients were respectively 16.56%,14.52% and 12.04%. The use amount ratios of essential medicines in the outpatient and emergency depart-ments in Beijing Friendship Hospital(a pilot hospitals of cancelling drug addition medical reform)in the 3 years were respectively 21.59%,19.85% and 22.93%;the use amount ratios of essential medicines of inpatients were respectively 17.70%,17.62% and 15.89%. The use amount ratios of essential medicines did not meet 25%-30% of the requirements. CONCLUSIONS:Cancelling the drug addition and adjusting the types and quantity of essential medicine list had no obvious effects on the use amount ratios of gen-eral third-level grade-A hospitals. It is suggested to promote the priority use of essential medicines by systems of medical insurance total amount prepayment,single disease payment or diagnosis related groups-based prepayment and the free policy of essential medi-cines,rather than administrative order.

Flow cytometry analysis of DNA ploidy level and S-phase fraction (SPF) was carried out in 24 snap-forzen tissue specimens of ovarian carcinoma. The relationship of DNA ploidy level and SP-F with age,clinical stage, ascites, histologic type,pathological grade,lymphocyte infiltration and psammoma bodies was analyzed.Results showed that the relationship of DNA ploidy level and SPF with ascites and pathological grade was significant. Aneuploid portion and SPF in patients with ascites or pathological grade Ⅲ or Ⅱ were higher than those in patients with no ascites or pathological grade I. The author considers that DNA ploidy level and SPF of ovarian carcinoma can serve as a relatively independent objective index which reflects tumor's biological behaviours,and will be of great auxiliary value to early diagnosis and therapy of ovarian carcinoma.

Percutaneous vertebroplasty has many advantages such as minimal trauma, simple mode of operation, rapid and correct therapeutic effect, high safety, and wide indications. Therefore it has been generally paid close attention and accepted. Percutaneous vertebroplasty has conspicuous curative effect, especially in vertebral compression fracture. Polymethyl methacrylate is the most used filling materials at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage of bone cement; Bolster for self-replacement can rebound vertebral body height, and balloon kyphoplasty and sky bone expander kyphoplasty can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used in the treatment of percutaneous vertebroplasty.

BACKGROUND: Extracorporeal shock wave therapy is indicated as an effective method for treatment of delayed fracture healing or nonunion. Osteoblasts plays an important role in this process.OBJECTIVE: To investigate the function of osteoblasts in the process of extracorporeal shock wave promoting fractures healing, and to provide theoretical support for improving shock wave therapy on fracture healing.METHODS: Primary cultured ostsoblasts were isolated from newbon SD rat calvaria and randomly divided into two groups, shock wave and control. Treated by different energies of extracorporeal shock wave, cells were incubated onto 96-well culture plate. An optimal dose of extracorporeai shock wave was selected according to survival and proliferation of osteoblasts. The osteoblasts treated by optimal energy of extracorporeal shock wave were cultured and harvested for the analysis of alkaline phosphatase by calcium cobolt stain, cell survival by CCK-8 Kit, alkaline phosphatase expression by AKP kit, mineralized nodules by Alizarin red staining, integrin β1 and β1 mRNA expressions by flow cytometry and RT-PCR, cell migration by wound healing assay.RESULTS AND CONCLUSION: The optimal energy of extracorporeal shock wave treating primary cultured osteoblasts was 10 kV (500 impulses). Following extracorporeal shock wave therapy, the cell proliferation, alkaline phosphatase activity, cell mineralization, rates of cell adhesion, as well as β1 integrin and its mRNA expressions were increased as compared with those in control group (P < 0.01). Further distance of cell migration was found in extracorporeal shock wave group (P < 0.05). The results showed that the optimal energy of extracorporeal shock wave could promote the proliferation, differentiation, adhesion and migration of osteoblasts in vitro, and β1 integrin may play an important role in the process of cell adhesion and migration.
