Objective To investigate the change of insulin-like growth factor Ⅱ(IGF-Ⅱ) and its relation with infection in severely burned patients.Methods RIA method was used to determine the serum IGF-Ⅱ level in patients with severe burn.Results Compared with control group, the level of IGF-Ⅱ was increased significantly at 5 postburn days , and persistent 35 days (P0 05).Conclusion IGF-Ⅱ is involved in the pathogenesis of burn , and closely correlated with the infection after burn.

Objective To investigate the effect of UCP2 on cell proliferation, apoptosis, metastasis in cervical squamous carcinoma. Methods Plasmid?mediated downregulation of UCP2 was obtained in cervical cancer cell lines. MTT, flow cytometry and transwell chamber assay were conducted to detect the ability of proliferation, apoptosis and metastasis. Characteristics of UCP2 protein was analyzed by bioinformatics methods. Results (1)UCP2 was verified to be downregulated by qRT?PCR and Western blotting assay.(2)MTT, apoptosis assay and transwell chamber assay showed that the proliferation of SiHa cell was significantly inhibited, and the apoptosis rate was significantly increased, and metastasis was markedly deduced (P < 0.05). (3) Bioinformatic analysis showed that UCP2 was located in mitochondria with several phosphorylation sites, and UCP2 interacted with other proteins to produce biological effects. Conclusion UCP2 may play an important role in the occurrence and development of cervical cancer, and it is expected to be a new target for the early diagnosis and treatment of cervical cancer.

Objective To study the protective effect of estrogen on cerebral ischemia reperfusion injury in rat Methods 120 adult female rats were randomly divided into the intact, ovariectomized(OVX),OVX and estrogen(E 2) replacement groups In the OVX+E 2 group, E 2 valerate(200 ?g/kg) was subcutaneousely injected once a week after the OVX Four weeks after the OVX, all rats were subjected to model of ischemia reperfusion by MCAO Infarct volumes were measured.Pathological changes and apoptosis was detected, and serum estrogen concentration was analyzed Results For different time of ischemia reperfusion,cerebral infarct volume in the OVX+E 2 group was minimal,and in the OVX group was maximal(all P

Objective To investigate the protective effect of Schizandrae Lignanoid(SCL)on the apoptosis of PC12 cells induced by H2O2 and its relative mechanisms.Methods PC12 cells were divided into four groups: control group,model group,high dose SCL(SCL1) group,and low dose SCL(SCL2) group.Apoptosis of PC12 cells was induced by H2O2.The cell activity was determined by MTT,the cell apoptotic rate was determined by Annexin V-FITC/PI and ??m was detected by flow cytometry.The expressions of bcl-2 and bax were detected by immunohistochemistry.Results Compared with model group,SCL increased the survival rate of PC12 cells(P

Currently all military hospitals attach great importance to the management of state-owned assets.However,there still exist some problems,such as weak management consciousness,irregular assets disposing and loose connections between management and accounting.The author ventures some measures to strengthen management consciousness,organization establishment,accounting procedures and monitoring mechanism.

Objective:To investigate the change of the serum IL-18, sFas and sFasL levels in patients with severe burn and its correlation with the morbid condition and outcome Methods:Thirty patients, including three fatal cases, had burn with a total burn surface area (TBSA) of 30% or more 45 healthy volunteers were as control group The serum IL-18, sFas and sFasL levels were measured by enzyme-linked immunosorbent assay (ELISA) at various time points ( 1, 3, 5, 7, 14, 21, 28 and 35 days) burn later Results:Compared with control group, the levels of IL-18, sFas and sFasL of patients increased significantly after burn (P

Confocal microscope and flow cytometry were used to study the adhesion and the expression of adhesive molecules between different metastatic lung cancer cells and endothelial cells (EC) in vitro. Tea polyphenols (TP) were tested for their effect on tumor cell endothelial adhesion.The results showed that the adhesion and expression of CD44?CD54 were significantly higher in PG cells than those in D9 cells. Treatment of EC monolayers with LPS(0 5ug/ml) for six hours caused an increase in adhesion of PG to EC and adhesive molecules expression. TP could inhibit the adhesion of PG to EC and expressions of CD44 and CD54 in dose dependent manner. It suggested that adhesion molecules might play an important role in mediating the adhesion of lung carcinoma to EC and hematogenous metastasis; TP had an inhibitory effect on metastasis of lung cancer.

A volunteer was scanned by spiral CT,the Dicom format images were imported into Mimics software to reconstruct 3-D mandibular model,then optimized by Geomagic and meshed in Ansys software. A good geometric precise three-dimensional finite element model was constructed. The displacement of dentition was similar with clin-ical situation by computer.

Objective To summarize the current value of neoadjuvant chemotherapy(NAC) for potentially resectable gastric cancer.Methods The recent 5-year literatures searched through the PubMed with the key words:stomach neoplasm,gastric cancer/carcinoma,neoadjuvant therapy/chemotherapy and preoperative therapy/chemotherapy as well as the relevant reports presented in the ASCO Annual Meeting in 2007 and 2008 were analyzed.The present status of NAC for advanced gastric cancer was summarized,the necessity and feasibility were evaluated,and the patients features for selecting,the predictors for response,the mainly existing problems and development trend of NAC were analyzed.Results At present,there were 7 randomized control trails(RCT) published,and among them 3 were phase Ⅲ.It was safe,effective and feasible to most of trails in NAC for gastric cancer.However,it was still little to obtain survival benefit for NAC RCT,and short of randomized trial comparing strict preoperative chemotherapy to surgery alone or perioperative chemotherapy to surgery plus adjuvant chemotherapy.It remained lots of problems such as how to select the appropriate patients,the effective induced regimes and the predicted factors,the evaluated indices for response.Conclusion NAC is a safe,feasible and efficient method to potentially resectable gastric cancer,but strict phase Ⅲ randomized trials are needed.In the future,substantial improvements of treatment outcome will likely depend on the novel drugs and molecular biological targeted therapies.

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.
