Objective To know the role of inhibitor of DNA binding 2(Id2) in the development of neural stem cells(NSCs) in the anterior subventricular zone(SVZa). Methods To examine the expression of Id2 in SVZa,rostral migratory stream(RMS) and olfactory bulb(OB) in E14,P0,P7,P14,P30 adult and old rat brains by reverse transcriptase-polymerase chain reaction(RT-PCR),Western blotting and immunohistochemistry. Results The expression of Id2 peaked at the area of RMS,and was less positive in SVZa and the least in OB at different time courses of developing rat brains.The expression of Id2 in the three areas in E14 were higher than that on the postnatal day,higher in OB and RMS in adult than that on P0,and remain high in old.However,the expression of Id2 in SVZa in adult was weaker than that on P0.Conclusion The expression of Id2 in the deveolpment of SVZa NSCs indicates that Id2 plays an important role in blocking the differentiation of SVZa NSCs and increasing the proliferation of SVZa NSCs.

Objective:To evaluate the effects of domestic recombinant adenovirus p53 injection (rAd-p53,Gendicine) combined with cisplatin (DDP) on growth and apoptosis of ovarian carcinoma cell lines. Methods:MTT assay, flow cytometry, and Western blotting were used to compare the effects of rAd-p53, DDP and their combination on the growth, cell cycle, apoptotic rate, and p53 protein expression of ovarian carcinoma cell lines. Results:rAd-p53 inhibited ovarian carcinoma cells proliferation in dosE- and timE-dependent manners. After combined treatment, the growth inhibition rate was significantly increased (P<0.01). There was no significant diffE-rence in the inhibition potency induced by combined treatment with different sequences (P>0.05). Combined treatment significantly arrested ovarian carcinoma cell lines in G0/G1 phase at 72 h, the cell number in S phase was significantly decreased and the apototic rate was significantly increased (P<0.01). High expression of p53 protein was detected in ovarian carcinoma cell lines at 72 h after administeration of rAd-p53. Conclusion:rAd-p53 tranfects the exogenous widE-type p53 into the genome group of human ovarian tumor cells, induces p53 protein expression, thereby arresting tumor cells at G0/G1 phase, inhibiting tumor growth, and inducing apoptosis.

Objective To investigate the relationship between homocysteine(Hcy)and blood uric acid(UA)in the patients with type 2 diabetes mellitus(T2DM)complicating hypertension.Methods 85 patients with T2DM complicating hypertension were se-lected as the groupⅠ,78 patients with simple T2DM as the group Ⅱ and 74 individuals with healthy physical examination as the group Ⅲ.Hcy,UA,TC,TG and HDL-C were measured in all the subjects.Results Compared with group Ⅲ(control),the levels of Hcy,UA,TC and TG in the group Ⅰand groupⅡwere significantly increased(P <0.05),but the level of HDL-C was significantly decreased(P <0.05).Compared with the group Ⅱ(T2DM),the levels of Hcy,UA,TC and TG in the group Ⅰwere significantly in-creased(P <0.05 ),but the level of HDL-C was obviously decreased,the difference had statistical significance (P <0.05 ).There was good positive correlation between the Hcy level and the UA level in the patients with T2DM complicating hypertension (r =0.658,P <0.05).Conclusion The levels of Hcy and UA are significantly increased in the patients with T2DM especially complica-ting hypertension.High Hcy and high UA are the important risk factors of T2DM complicating cardiocerebrovascular diseases.

Objective To observe the effects of parecoxib sodium on laparoscopic cholecystectomy ( LC ) patients after remifentanil fast track anesthesia.Methods 120 patients underwent general anesthesia for laparoscopic cholecystectomy were divided into two groups using random number table,60 cases in each group.The observation group was injected parecoxib sodium 40mg+saline solution 5 mL,while the control group was injected only saline so-lution 5mL prior to induction of anesthesia.The heart rate,mean arterial pressure,awaked time,pain score,agitation score and adverse reaction were compared.Results 5, 15, 30min after extubation, heart rate were ( 75.7 ± 4.8)times/min,(79.3 ±6.2)times/min,(74.2 ±5.2)times/min in the observation group and (85.2 ±3.8)times/min, (88.2 ±5.9)times/min,(86.1 ±6.2)times/min in the control group,and the mean arterial pressure were (103.5 ± 11.3)mmHg,(104.7 ±12.6)mmHg,(108.4 ±12.7)mmHg in the observation group and (132.3 ±16.3)mmHg, (135.2 ±14.6) mmHg,(133.6 ±11.8) mmHg in the control group,there were statistifically significant differences (t=4.722,4.357,4.236,4.732,4.367,4.063,all P <0.05).The pain score,agitation score were (2.5 ± 0.9)points,(1.4 ±0.8) points in the observation group,which were lower than (4.2 ±1.2) points,(3.2 ± 1.2)points in the control group(t =4.232,5.234,all P<0.05).Conclusion Parecoxib sodium can reduce the fast-track anesthesia agitation and pain,improve hemodynamics and stress response in LC patients.

Objective To explore the correlation between delirium and dementia in elderly patients undergoing hip fracture surgery.Methods A prospective study was conducted on 118 elderly patients with hip fracture who were free from prefracture dementia.Caregivers or the relatives described the patients' prefracture cognition by the Informant Questionnaire on Cognitive Decline in the Elderly-short form (IQCODE SF).Delirium was assessed by the Confusion Assessment Method (CAM).After 6 months,cognition was reassessed by using 5 cognitive tests,taking DSM-Ⅳ as the diagnostic criteria.Results Among 32 cases (27％) suffered from delirium in the acute phase,12 cases (38％) reached to the diagnostic criteria of dementia after 6 months follow up,while there were 6 cases (7％) reached to the diagnostic criteria of dementia after 6 months follow-up in the group without delirium in the acute phase (x2 =16.81,P＜0.001).IQCODE-SF score had no statistically significant difference in the prediction of dementia.Conclusions In elderly patients without the history of dementia,delirium after hip fracture surgery is the major predictor of dementia within half years.

BACKGROUND:There is no consensus on the choice of anatomic plate or dynamic hip screw for the treatment of intertrochanteric fracture. Current research is limited to smal-sample studies, and it is difficult to carry out a large-sample multicenter analysis. OBJECTIVE:To carry out Meta-analysis about the literature on anatomic plate versus dynamic hip screw in the treatment of intertrochanteric fractures, in order to evaluate the efficacy of anatomic plate versus dynamic hip screw in the treatment of intertrochanteric fractures. METHODS:The PubMed database (1995-2013), EMCC database (1995-2013), CBM database (1995-2013), CNKI database (1995-2013), VIP database (1989-2013) and Wanfang database (1995-2013) were searched by computer to col ect the control ed trials of anatomic plate versus dynamic hip screw for the treatment of intertrochanteric fractures. Then, the retrieved studies were screened according to predefined inclusion and exclusion criteria. The quality of the included studies was evaluated to extract useful y data, and Meta-analysis was performed by using the RevMan5.0 software. RESULTS AND CONCLUSION:A total of 19 control ed trials were included with a total of 1 730 cases. Among them, 764 cases were belonged to the anatomic plate group, and dynamic hip screw group included 966 cases. The Meta-analysis results indicated that there were no statistical y significant differences in fracture healing time, prognosis excellent and good rate and postoperative complications between two groups (P=0.34, 0.58, 0.80);the operative time, intraoperative blood loss and postoperative drainage volume in the anatomic plate group were lower than those in the dynamic hip screw group (P<0.000 01). The results indicate that anatomic plate and dynamic hip screw have the similar clinical efficacy for the treatment of intertrochanteric fractures, but the anatomical plate has relatively simple operation and less bleeding. Due to the poor quality of the included literatures and high bias occur and influence the effect, so more wel-designed multi-center randomized control ed trials should be performed to provide high-quality evidence.

Objective The research is to study the temperature rising situation in the thermochemotherapy process of the domestic dog through the hepatic artery, and the bearing ability of heart, liver, and kidney during the process, as well as the biochemical and histological change of the liver after the procedure. Methods A thermostated container of water bath and an infusion pump, both designed domestically, were adopted. Ten domestic dogs were divided into 2 groups of A and B with 5 dogs respectively. Through hepatic artery infusion for group A, glucose solution (GS) was administered at 43?C for 30 minutes, with the flowing rate of 30ml/min, in group B 5% GS at 45?C for 30 minutes, with the flowing rate of 40ml/min added with chemotherapy drug MMC(0.2mg/kg) was administered to 3 dogs and 5% GS with the same flowing rate added with CDDP(1mg/kg) into other 2 dogs. Results The temperature of anus and liver was 0.3～0.5?C and 0.5～1.0?C higher than before the procedure respectively, there was no significant rate changes of heart and respiration during and before the procedure. Four dogs were radiographied after 15 minutes' infusion, showing different degrees of hepatic artery dilation accompanied with relevant increase of infusion. Six dogs were radiographied after 30 minutes' infusion, 5 of them showed arterial contraction astescal on accompanied with relevant decrease of infusion. There appeared slight or moderate increase of aminopherase after the procedure, but in actually returned to normal within a week. Pathologically, there appeared no acute effect on heart, lung and kidney other than slight and reversible damage to hepatic tissue. Conclusions Healthy dogs can endure the chemotherapy treatment of infusion through hepatic arterial fistula at 43?C 45?C for 30 minutes.
