OBJECTIVE:To investigate the current situation of cranial scaffold for the treatment of craniocerebral injury,analyze biocompatibility of the cranial scaffold,and observe the cranial scaffold-induced complications. METHODS:A computer-based online search was conducted in CNKI and Medline database in accordance with inclusion and exclusion criteria from 1988 to 2009. A total of 37 articles were included in the final analysis,which were summarized based on application situation of cranial scaffold for the treatment of craniocerebral injury,biocompatibility of cranial scaffold,and cranial scaffold-induced complication. RESULTS:Cranial scaffold had a good effect on the treatment of craniocerebral injury which was hard to be treated using surgical intervention and drug therapy. The biocompatibility of cranial scaffold might influence its security and efficiency. The poor biocompatibility of cranial scaffold increased incidence of varying complications,including thrombosis,cerebral hemorrhage,restenosis,hypertransfusion,and hypoperfusion. Therefore,patients should be cared carefully following scaffold implantation. CONCLUSION:Cranial scaffold implantation has a good effect on the treatment of craniocerebral injury; however,its biocompatibility to human body may cause complications which attract much attention by physicians.

AIM To observe effects of IBMX on cGMP and GFAP production in gerbil hippocampus after recirculation following ischemia. METHODS Bilateral occlusion of common carotid arteries and immunofluorescent stain methods in gerbil hippocampal tissue slice were used. RESULTS Recirculation following ischemia leads to a rise in hippocampus cGMP and GFAP concentration. cGMP and GFAP positive cells mainly distributed in rediatum layer and molecular layer in the CA 1 subfield, Most of cGMP positive cells are astrocytes under double immunofluorescent stain. Most of cGMP strong positive cells are also those of GFAP strong positive cells. IBMX increased cGMP and GFAP production. CONCLUSION cGMP is possible to play an important role in the activation or regulation of GFAP in the hippocampus.

ObjectiveTo identify the influence of cholesterol on insulin-secreting cells.Methods MIN6 mouse insulin cells were cultured in vitro. After confluence of cells, on one hand, free cholesterol in series concentrations was added to cultu re medium to act for 24 hours, and on the other hand, free cholesterol in same c oncentration was added to culture medium to act for different periods. MTT test was used to evaluate the viability of MIN6 cells.Results25μmol/L free cholesterol significantly decreased the viability of MIN6 c ells after 24 hours and 100μmol/L free cholesterol significantly decreased the viability of MIN6 cells after 12 hours and induced cells death after 24 hours.Conclusions Free cholesterol decreases viability of MIN6 cells in a dose-dependent and time-dependent manner, and it is indicated that elevated free cholesterol concentration in blood may be one factor involved in the dysfunction of pancreatic β-cells.

ObjectiveTo identify the differences between acetylcholine(Ach)-induced increase and adenosine triphosphate(ATP)-induced increase in cytosolic free Ca2+ concentration ([Ca2+]c) in mouse pancreatic β-cells. MethodsMouse pancreatic β-cells were primarily cultured and divided into two groups,one group was stimulated by Ach and another by ATP.[Ca2+]c was recorded with Fura-2 in normal condition, chelation of extracellular Ca2+ by EGTA and depletion of intracellular Ca2+ stores by Thapsigargin.ResultsAch induced a transient peak increase and sustained increase in [Ca2+]c. ATP induced a transient peak increase and no sustained increase. Chelation of extracellular Ca2+ by EGTA eliminated the sustained increase induced by Ach, and did not eliminate the transient peak increase induced by Ach and ATP. Depletion of intracellular Ca2+ stores by Thapsigargin eliminated the transient peak increase induced by Ach and ATP and the sustained increase induced by Ach. ConclusionsAch induces intracellular Ca2+ release and the following Ca2+ release-activated Ca2+ influx, and ATP induces intracellular Ca2+ release, but blocks the following Ca2+ release-activated Ca2+ influx.

Objective To understand treatment outcomes of patients diagnosed with type 2 diabetes aged over 30 years in Jiangninglu Neighborhood of downtown Shanghai. Methods Total 642 patients diagnosed as type 2 diabetes aged over 30 were investigated by cluster sampling in Jiangninglu Neighborhood of downtown Shanghai. Status of optimal control of diabetes in them was analyzed based on the recommendations proposed by International Diabetes Federation (IDF) for Western Pacific Region. Results and serum level of glycosylated hemoglobin Alc (HbAlc) of less than 6.5% was achieved in 37.5% (241/were achieved in 23.8% (153/642) and 18.1% (116/642) of them, respectively, and beth systolic and mmol/L was achieved in 21.7% (139/642) of all the participants investigated, triglyceride of less than 1.5 mmol/L in 46.6% (299/642), low-deusity lipoprotein-cholesterol (LDL-C) of less than 2.5 mmol/L in 23.7% (152/642) and high-density lipoprotein-cholesterol of greater than 1.1 mmol/L in 62.1% (399/of their blood glucose, blood pressure and serum LDL-C (defined as HbAlc less than 6.5%, blood pressure less than 130/80 mm Hg and LDL-C less than 2.5 retool/L). Conclusions Only 2.6% of all the patients diagnosed with diabetes aged over 30 in downtown Shanghai get optimal control of their blood glucose, blood pressure and serum lipid, so comprehensive prevention and control for diabetes shall be strengthened for them at community-level of urban areas.

BACKGROUND: The effectiveness of femoral nerve block in perioperative analgesia for total knee arthroplasty has been widely recognized, but the need for combined sciatic nerve block remains controversial.OBJECTIVE: To investigate the analgesic effect and rehabilitation training of femoral and sciatic nerve block in the perioperative period of total knee arthroplasty. METHODS: 150 patients undergoing total knee arthroplasty were randomly divided into three groups: general anesthesia, femoral nerve block and femoral and sciatic nerve block groups. The visual analogue scale scores at rest and in activity, range of motion of the knee, postoperative hospitalization time, adverse effects and the Hospital for Special Surgery scores were recorded and compared among groups.RESULTS AND CONCLUSION: (1) The order of visual analogue scale scores at rest and in activity at each time point postoperatively was as follows: general anesthesia group > femoral nerve block group > femoral and sciatic nerve block group (P < 0.05). (2) The range of motion of the knee at different time points postoperatively was largest in the femoral nerve block group, followed by the femoral nerve block group, and smallest in the general anesthesia group (P < 0.05). (3) The postoperative hospitalization time in the femoral nerve block and femoral and sciatic nerve block groups was significantly less than that in the general anesthesia group, and the time in the femoral and sciatic nerve block group was significantly less than that in the femoral nerve block group (P < 0.05). (4) The Hospital for Special Surgery scores at 1 month postoperatively in the femoral nerve block and femoral and sciatic nerve block groups were significantly higher than those in the general anesthesia group, and the scores in the femoral and sciatic nerve block group were significantly higher than those in the femoral nerve block group (P < 0.05). But the Hospital for Special Surgery knee scores at 3 and 6 months postoperatively did not differ significantly among groups (P > 0.05). (5) These results indicate that the femoral and sciatic nerve block has better postoperative analgesia effect compared with general anesthesia and femoral nerve block under multimodal analgesia in total knee arthroplasty, which is favorable for early rehabilitative training.
