Objective To systematically review the risks and effectiveness of combined caudate lobectomy in Klatskin tumor.Methods A systematic literature search was conducted on PubMed,Embase,Cochrane Library,Scopus,CNKI databases and Chinese Bio Medical Literature (CBM).A systematic review and meta-analysis of the current literatures were conducted based on the PRISMA guideline.Odds ratios were calculated using the Mantel-Haenszel method.The primary outcome variables included safety,effectiveness of combined caudate lobectomy and its impact on long-term survival.Results Nine out of 312 articles were included.Results showed caudate lobectomy did not increase the incidence of postoperative complications (OR ＝ 1.15；95 ％ CI 0.74-1.81；P ＞ 0.05),but improved R0 resection rate (OR ＝ 4.81；95 ％ CI 2.72 ～ 8.53；P ＜ 0.01) and long-term survival in these patients (OR ＝ 0.20；95％ CI 0.11 ～ 0.39；P ＜0.01).Conclusion Combined caudate lobe resection is a safe and effective treatment for Klatskin tumor.

Hypoxic pulmonary hypertension(HPH) is a common disease featured by acute hypoxic pulmonary vasoconstriction(HPV) and chronic hypoxic pulmonary vascular remolding(HPVR) leading to the sustained increasing of pulmonary artery pressure.There are many mediators involved in the HPH but none can illustrate it successfully.Primary work has found 15-lipoxygenase(15-LO) and its catalyzed production 15-hydroxyeicosatetraenoic acid(15-HETE)(from arachidonic acid) are up-regulated in pulmonary vascular when exprosed to hypoxia.And it has been found 15-LO/15-HETE involved in many processes of both the HPV and HPVR,indicating 15-LO/15-HETE may be an important mediator of HPH.Advances research on 15-LO/15-HETE may illustrate the mechanism of HPH,and will give some message in looking for a potential clinical target of HPH.

Objective To discuss the use management of both war and peace time for medical equipment in field clinics. Methods Medical equipment was sent to different departments which are personal management. Results The usage management can improve the capacity of using and maintaining of medical equipments. Conclusion The management method improves field medical treatment ability of field clinics and adapts the usage management of medical equipments in field clinics.

Objective To analyze and solve the difficulties in rapidly expanding the mobile field hospital in earthquake relief mission.Methods Aimed at the difficulties in the speed,advance men were sent out before the expansion.Then the personnel were regrouped in the proceeding of the expansion,and the vehicles entered the district according to the predefined area and order.Results The expanding speed was raised.Conclusion The scheme meets the requirements of the first aid in the mobile field hospital.

[Objective]To compare the biomechanical effect of minimally invasive injectable graf X_3(MIIGX_3) on strengthening pedicle screw fixation with that of bone cement.[Method]Eight fresh pig lumbar vertebrae were harvested.One track was made in each vertebral pedicle.Before pedicle screw fixation,one track of one side bertebra was augmented with MIIGX3,and another side vertebra with bone cement.Pullout test was performed 24 hours after the fixation,and maximum axial pullout strength was measured.[Result]The maximum axial pullout strength is 1915 N?375 N in MIIGX3 group,and 3625 N?775 N in bone cement group.There was significant difference between two groups(P

Objective To study time-dependent degradation of DNA in lymphocytes in the human bloodstain in order to estimate aging of bloodstain.Methods Lymphocytes were isolated from the human bloodstain placed under room temperature and were analyzed by single-cell gel electrophoresis(SCGE).The percentage of DNA-degraded lymphocytes were calculated in the cloodstain placed at different time intervals from 0 to 72h under fluorescent microscope connected with auto-analysis-image system.Results The percentage of DNA degraded lymphocytes was closely correlated with time lapse within 72h.A regression equation was formulated with R=0.9522(P

Objective [WT5”BZ]To improve recognition and differential diagnosis of splenic space occupying disease.[WT5”HZ]Method [WT5”BZ]40 cases admitted from 1983 to 1999 were analyzed retrospectively。[WT5”HZ]Result [WT5”BZ]Twenty six out of 40 cases were of benign splenic disease including one case of cyst, 3 cases of splenic abscesses, 7 cases of splenic tuberculosis, 5 cases of splenic “true” cyst, 4 cases of splenic angiolymphoma, 3 cases of splenic aneurysm, and one each of splenic lymphoangioma, epidermoid cyst and hamartoma. There were 14 cases of malignant tumor, amongwhich,there were two cases of non Hodgkin′s lymphoma and two of leiosarcoma,one angiosarcoma and metastatic splenic malignant tumor in 9 cases.[WT5”HZ]Conclusion [WT5”BZ]Therapeutics should be adopted according the nature of splenic diseases, based on clinical and image characteristics.

This paper discusses issues involved in the deployment of the shelters of campaign-grade rapid medical support system in such aspects as entering of the vehicles,unloading of the shelters and grouping of the staffs. It suggests that the vehicles should rapidly move in at their positions and be butted bidirectional. As the system is deployed,such things should all be fixed as the position of the vehicles & equipments as well as the deployment motions and sequence. The system is positioned at hard surface,the shelters should be pushed towards the immobilized vehicles,but for the system located at soft surface,it is quite the contrary. With the above-mentioned measures implemented,the duration for shelters of campaign-grade rapid medical support system can be reduced largely.

Objective To Observe both curative and side effects of rhIL-11(recombinant human interleukin 11)in preventing and curing thrombocytopenia caused by chemotherapy.Methods From May 2003 to May 2004,research was done in the Department of Oncology,General Hospital of Shenyang Military Region by adopting double-blind placebo contrast and self cross-over study methods on 42 non-small cell lung cancer patients who had received GC chemotherapy.The effects of rhIL-11 and placebo on the minimal number of thrombocytes and their toxins were compared.24 hours later after the medicine for chemotherapy was given,rhIL-11 was administered hypodermically to the patients at the amount of 25 ?g/kg for 7 to 14 days.When the thrombocyte number was higher than 300?10~9/L,the administration of rhIL-11 was stopped.Results RhIL-11 could obviously increase the minimal number of thrombocytes during chemotherapy and reduce the times for blood transfusion.The side of rhIL-11 were mild edema,weariness and symptoms of catching cold.Conclusion RhIL-11 plays an obvious role in preventing and curing thrombocytopenia caused by chemotherapy,and has safe and definite curative effects without serious effects.
