BACKGROUND: The differentiation of neural stem cells (NSCs) is an important for NSCs to be applied in clinical treatment. And whether the neurons differentiated from NSCs can be connected with other neurons or not comes into being a critical problem. OBJECTIVE: To observe the effect of nerve growth factor (NGF) on the growth and differentiation of in vitro cultured NSCs, and on the formation and growth of axons. DESIGN, TIME AND SETTING: The cytology in vitro experiment was performed at the Equipment Center of China Medical University from June 2007 to December 2008. MATERIALS: Three 2-3 day male Sprague Dawley rats were used in this study. NGF was purchased from Peprotech. METHODS: NSCs were isolated from neonatal rats by enzyme digestion and mechanical separation. At the fourth passage, cell clone masses received nestin immunocytochemistry. Remaining cells were dispersed by mechanical separation. Monoclone NSCs were incubated by limiting dilution assay, and made into 108 L-1 monoplast suspension in complete medium. NSCs were assigned into 2 groups. NSCs in the control group were incubated in 10% fetal bovine serum (FBS). NSCs in the induction group were incubated in the 10% FBS+50 ?g/L NGF for 5-7 days. The five isolated neurons with positive expression of neuron specific enolase (NSE) were observed. The number of axons was measured through concentric circles (37.5 ?m and 75 ?m diameter) circling neurons to detect the length of long axon. MAIN OUTCOME MEASURES: Cultured cells were identified by nestin, NSE and glial fibrillary acidic protein (GFAP) immunohistochemistry to test the number of neurons, number and length of axons. RESULTS: Neurospheres were Nestin-positive and could differentiate into the NSE-positive or GFAP-positive cells. At day 6, the numbers of neurons and axons were significantly more, and the length of longest axons was significantly longer in the induction group than in the control group (t=3.301, 2.982, 4.012, P

Objective To study protective effect and mechanism of caffeic acid phenethyl ester ( CAPE ) in rats with doxorubicin-induced myocardial injury.Methods Sixty male SD rats were randomly divided into control group, model group and CAPE ( 12、24、48 mg/kg ) groups.The models of doxorubicin-induced myocardial injury were established by injection of 2.5 mg/kg doxorubicin every other day for 6 times.After the last injection, model group was given distilled water and CAPE ( 12、24、48 mg/kg ) groups were fed with CAPE, one time a day for 8 weeks.After consecutive 8 weeks, serum creatine kinase, lactate dehydrogenase and BNP were assessed , NO concentration, MDA,GSH,SOD,NOS,LPO and CAT contents in the heart were determined and histopathological changes were detected.Results serum creatine kinase、lactate dehydrogenase and BNP of CAPE 48 mg/kg group decreased significantly(P<0.05), while the activity of NO,NOS,GSH,CAT and SOD increased in the CAPE 48 mg/kg group significantly ( P<0.05 ) .Histopathology showed caffeic acid phenethyl ester could improve the doxorubicin-induced myocardium injury. Conclusion caffeic acid phenethylester has the protective effects in rats with doxorubicin-induced myocardial injury.Protective effect may be related to improve myocardial against oxidative stress damage.

Objective To investigate the outcome after ventriculoperitoneal (V-P)shunt for post-traumatic hydrocephalus (PTH). Methods A retrospective study investigated the outcome of 51 patients after head injury, who had undergone V-P shunt due to PTH.The Glasgow outcome scale (GOS),age and intracerebral pressure(ICP) were analyzed. Results Twenty-two of 33 patients with COS 3 or less than 3 scores had clear-cut benefit from V-P shunt,while only 6 of 18 patients with GOS 4 scores did.Tbe GOS before V-P shunt had correlated with the GOS 6 months after operation. The patients with GOS 3 or less than 3 scores had good outcome than patients with COS 4 scores (P<0.05). Patients' age and ICP before the V-P shunt did not influence the outcome (P>0.05 ). Conclusion V-P shunt has much benefit for the patients with PTH, GOS before operation is a best predictive parameter for outcome after V-P shunt.

Objective To investigate the role of gastric acid in the esophageal adenocarcinogenesis induced by duodenal juice reflux in the rats. Methods Eight week old male Sprague Dawley rats, 125 in all, weighing approximately 200 g each, were used. Three types of surgical procedures were performed to produce gastroesophageal reflux (GER), duodenoesophageal reflux (DER) and duodenogastroesophageal reflux (DGER), and a group of sham operation (SO). The animals were fed with a standard diet. Esophageal mucosal pathological changes were examined 20 weeks after surgery. Results No pathological changes were found in the 15 SO rats animals. Significant esophagitis were observed in three reflux groups. In 35 DER and 32 DGER animals, the incidence of Barrett's esophagus (BE) was 91.4%, 84.4% respectively and the incidence of esophageal adenocarcinoma (EAC) was 25.7%, 53.1% respectively, significantly higher than those in the 24 GER animals ( P

Objective Aims To investigate the dynamic changes of multi-organ functional indices in esophageal carcinoma patients during peri-operation period at flatland and moderate high altitude. Methods 44 cases of esophageal carcinoma scheduled to receive gastroesophagostomy were categorized semi-randomly into three groups: Flatland control group (FCG, n=8), moderate altitude lung protection group (MPG, n=16), moderate altitude control group (MCG, n=20). The cases in FCG and MCG underwent routine pulmonary function examination and respiratory tract preparation peri-operatively. Besides the above routine treatment, the cases in MTG received administration of Rahdiola compound capsules preoperatively, with 2 pills a day. Blood-gas and biochemical indices of multi-organs were recorded in the three groups preoperatively and at 1, 3, and 5 days postoperatively respectively. The patients' systematic reaction, the changing trend of the indices reflecting organs function and the postoperative complication were observed. Results The blood-gas parameters were different significantly both preoperatively and postoperatively between the three groups. While other indices reflecting the organs function were not different significantly between the three groups before the operation, but at 1, 3, 5 days postoperatively, the indices in MCG and MPG were significantly different with that in FCG (P

Objective To know the state of endemic fluorosis,running state of water improvement project in Jiangsu Province,and to provide a scientific basis for adjusting control measures against the disease.Methods Nine key counties were selected from the endemic fluorosis areas as survey spots in Jiangsu in 2012.Three villages in each spot were selected as survey villages.To known the progress and running conditions of water facilities,water samples were collected to determine the fluorosis level.All children aged 8 to 12 were tested for dental fluorosis at the survey villages.The fluorine content in water was determined with F-selective electrode (WS/T 106-1999).Dental fluorosis was diagnosed byased on the Dean method.Results Twenty-seven villages were investigated,the number of villages that had water quality improved was 26,the rate was 96.30％ (26/27);the number of villages that did not have water quality improved was 1,the rate was 3.70％ (1/27).Among the 26 facilities,21 improved-water facilities ran normally,the rate was 80.77％ (21/26);2 facilities ran with intermittently water supply,the rate was 8.70％ (2/26);3 facilities were scraped,the rate was 11.54％ (3/26).In the villages with normal improved-water facilities and qualified water fluorosis,the total rate of dental fluorosis of children aged 8 to 12 was 22.74％ (380/1 761),the index of dental fluorosis was 0.45.In the villages with abnormal improved-water facilities and excessive water fluorosis,the total rate of dental fluorosis of children aged 8 to 12 was 66.51％ (143/215),the index of dental fluorosis was 1.45.The total rate of dental fluorosis of children aged 8 to 12 was 42.86％ (12/28) in the villages which had not changed water source,the index of dental fluorosis was 0.86.Conclusion Improvement of water decreasing fluorine project in Jiangsu Province has a certain effect on children's dental fluorosis,but some of the water fluorosis projects are scrapped,and excess fluorine water should be taken seriously.
