OBJECTIVE:To optimize the ratio of glycerol in Chloramphenicol and Ephedrine Nasal Drops included in China's Hospitals Agents Norms.METHODS:By formula optimization and observation on clinical trials,the ratio of glycerol in Chloramphenicol and Ephedrine Nasal Drops was reduced from 300mL to 50mL.RESULTS & CONCLUSION:The Chloramphenicol and Ephedrine Nose Drops prepared in an optimized ratio of glycerol is of much less irritability,good transparency,good compliance in patients,more reliable efficacy,thus deserving to be popularized.

Under the situation of national demand for cardiopulmonary resuscitation (CPR) skills, it is very important to develop a scientific and feasible education and training program to popularize CPR skills, and improve first-aid ability. This study illustrated the significance and feasibility of setting up car-diopulmonary resuscitation courses in colleges and universities. On this basis, specific suggestions and countermeasures were put forward to improve teaching organization and leadership, teaching material de-velopment, curriculum design, teaching faculty development, teacher training and laboratory construction. This study proposed to strengthen the legislation, and the implementation of first-aid qualification examina-tion in colleges and universities, making the students become the preferred educational group of CPR skills, which is of great significance to improve public popularity rate of CPR.

30 ?g/min were found to have retinopathy, but those with slightly increased UAE (15-30 ?g/min) showed a lower incidence of retinopathy similar to that of non-albuminuric diabetics. It indicates that UAE with 30 ?g/min may signal an imperative stage in preventing micro-vascular complications in diabetes.

In the present study, we observed the effects of cholinergic enhancement by pyridostigmine (PD), a cholinesterases inhibitor, on GH release in both normal (n = 13) and GH deficient children and adolescents (n = 8). Responses of GH to insulin hypoglycemia were also observed. In the normal subjects, PD-induced serum GH peak levels were significantly higher than that induced by insulin (P

OBJECTIVETo investigate the expression and significance of CD151 in pituitary adenomas.

METHODSThirty-six pituitary adenomas were collected immediately after surgery together with five normal pituitary tissue. Real time-PCR, Western blot and immunohistochemistry analysis were performed to detect the expression of CD151 mRNA and protein in thirty-six pituitary adenomases and five normal pituitary tissues.

RESULTSThe expression of CD151 in all pituitary adenomases was observed to be significantly higher than that in normal pituitary tissues by Western blot, real time PCR, and immunohistochemistry analysis (P < 0.01). The expression levels of protein and mRNA in invasive pituitary adenomas were much higher than those in non-invasive pituitary adenomas (P < 0.01).

CONCLUSIONThe results suggested that the expression of CD151 was closely correlated with malignant degree of pituitary adenomas, which indicated the expression of CD151 was intimately correlated with occurrence and development of pituitary adenomas. Detecting CD151 might be a vital index to predict prognosis of pituitary adenomas.

Objective To investigate the characteristics of attention networks impairment in Parkinson' s disease patients.Methods Attention network test was performed in 28 PD patients and 28 normal controls on the efficiency of three anatomically defined attentional networks:alerting,orienting,and executive control.Results The correct rate of attention network test was significantly lower(P0.05).The relative analysis showed that the Hoehn Yahr stage was positively correlated with the value of executive netwok(r=0.794,P

Dilated cardiomyopathy (DCM) is the most frequent pattern of non-ischemic cardiomyopathy with poor prognosis and high mortality.Studies in recent years found that non-coding small RNA molecules (miRNA) were closely related to the clinical course of DCM.The present article made a review on the expression pattern of miRNA and development of DCM study.

This study is designed to obtain recombinant human acetylcholinesterase (rhAChE) and apply it in screening acetylcholinesterase inhibitors. The rhAChE was overexpressed in HEK293 cells transfected by plasmid of pCMV-AChE with the cationic liposome and rhAChE was found to be secreted into cell culture medium. AChE activity was assayed according to modified Ellman method to obtain kinetic parameters. IC so50 values for donepezil compounds of rhAChE were calculated to determine their activities of inhibition. The results showed that Km value was 151.9 micromol.L-1 donepezil inhibited rhAChE in a mixed competitive-noncompetitive way (Ki= 16.03 nmol.L-1, Ki = 18.36 nmol.L-1) and that most new compounds tested exhibited high activities of inhibition on rhAChE. The study suggests that rhAChE is available to be applied in screening AChE inhibitors in vitro.

Garrès osteomyelitis is a specific type of chronic osteomyelitis that most commonly occurs in young patients, secondary to dental infection, and affects the unilateral side of the mandible. Bilateral mandibular Garrè's osteomyelitis is rare. In this article, a case of Garrè's osteomyelitis with bilateral mandible is reported. Its etiology, clinical pathologic features, diagnosis, differential diagnosis, and treatment methods are discussed by reviewing relevant literature.

BACKGROUND:Dural repair materials in current application mainly include autologous tissue repair material, alograft material, heterogeneous biological material and synthetic material, most of which are imported products with expensive price. OBJECTIVE: To evaluate safety and efficacy of a new biological type dura mater patch made in China based on animal experiments. METHODS:Bilateral dura mater defect models were established in 24 healthy domestic dogs: on the left side of the implant model, a new type biological dura patch was transplanted as experimental group; on the right side, another brand artificial dura patch that was on sale was transplanted as control group. After 1, 3, 6 and 12 months of implantation, we compared degradation, angiogenesis, growth and surrounding tissue reaction of dural substitutes of the experimental group and control group by hematoxylin-eosin staining, detected residual dose of epoxy-cross-linked agent in dogs’ blood and cerebrospinal fluid by fluorescence spectrophotometry. RESULTS AND CONCLUSION: During 1-12 months of implantation, al dogs grew wel and no infection or motor disorder was observed. Pathological examination showed that dura substitutes of the experimental group and control group had good biocompatibility, no or slightly inflammatory response. After 6 months of implantation, the surface of the new biological dural substitute (experimental group) was degraded and became a transit-state biomaterial with surrounding tissue, but the control group materials showed no degradation. After 12 months of implantation, the dura patch in the experimental group degraded nearly 50%, which appeared with neovascularization; while, the dura patch in the control group degraded 30%, and neovascularization was observed in only a smal amount of samples. Epoxy compounds of cross-linked agent were not detected in dogs’ blood and cerebrospinal fluid after 1, 3, 7 and 14 postoperative days. These findings show that this new type of biological dural substitute is a safe and effective dural repair material.
