Objective To observe the effectiveness of high-intensity focused ultrasound(HIFU)in the treatment of lichen sclerosus of vulva.Methods 63 patients with lichen sclerosus of vulva between July 2005 to December 2005 were divided into two groups at random,ultrasound group and control group.Patients in ultrasound group were treated with HIFU.Those in control group were treated with hormone.Results The scores of itch had difference after treatment in both group(P

Wistar rats randomly divided into groups A,B and C were killed at 2、3 and 12 days after transplantation,respectively.The pathological changes of the donor livers were observed by light microscope and electron microscope.The findings demonstrated that:(1)in the group A there was hepatocellular regeneration including hypertrophy of nuclei and nucleoli,and hyperplasia of mitochondrions and endoplasmic reticula;(2)in the group B the morphologic changes of the allografts involved in distinet fatty degencration and mitochondrial swelling of hepatic cells and peripheral vesscl wall infiltration by monocytes and lymphocytes;(3)in the group C hepatocellular loss with the massive tissue necrosis and fibroplasia occurred in the gratfs.From the above it was concluded that hepatocellular necrosis or loss related to the rejection 12 days after the transplantation might lead to the liver failure in the rats.

Objective:To discuss how to link the “No. 1 Military Medical Project”hospital network system with the local health insurance system.Methods: To analysis the interface demands of the social health insurance system and the rural cooperative health insurance system. Results: To solve the problem by modify the medical insurance interface program of the out-patient registration and charge, the in-patient registration and charge.Conclusion: the function and requirement has been realized by linking.

BACKGROUND:There may be tumor stem cells during metastasis and recurrence of liver cancer.The number of tumor stem cells is very few,so it is difficult to be identified.Thy-1 is a surface marking protein of oval cells.Specific marker can indirectly confirm the existence of tumor stem cells in the tumor,which is a focus in recent studies.OBJECTIVE:To study whether Thy-1 positive marked oval cells was expressed in hepatoma carcinoma cells,and investigate its screening and identification.METHODS:Flow cytometry was used to identify that Thy-1 positive expression in hepatoma carcinoma cells HepG2 and BEL-7402 and normal hepatocytes QSG-7701.Immunomagnetic bead sorting was utilized to select hepatoma carcinoma cells with Thy-1.Immunofluorescence was used to identify selected efficiency.Naked mouse inoculated with hepatoma carcinoma cells in the skin test was assigned to three groups.In the Thy-1~+ cells group,naked mice were inoculated with Thy-1~+ cells (5×10~5/mouse)underneath the skin of the back.In the HepG2 cell positive control group,naked mice were inoculated with HepG2 cells(0.5×10~7/mouse)underneath the skin of the back.In the Thy-1' cells negative control group,naked mice were inoculated with Thy-1~- cells(0.5×10~7/mouse)underneath the skin of the back.Tumorigenicity in each group was observed one month later.RESULTS AND CONCLUSION:Thy-1 expression in hepatoma carcinoma cells HepG2 and BEL7402 was significantly greater compared with normal hepatocytes QSG7701(P＜ 0.05).Positive rate of immunofluorescence staining was 85% in the Thy-1~+ cell group,1% in the HepG2 cell positive control group,0% in the Thy-1~- cell negative control group.There were nubble of five mice in HepG2 cell positive control and Thy-1~+ groups,and the volume was large.However,there was one nubble in Thy-1~- group,and the volume was significantly small(F=144.568,P＜ 0.05).Results indicated that hepatoma carcinoma cells contained Thy-1 labeled positive oval cells-like stem cells,which may be tumor stem cells in hepatoma carcinoma cells.

Objective To evaluate the effects of glutamine on immune function in elderly patients with malnutrition.Methods Twenty-four elderly patients with malnutrition were equally randomized divided into glutamine group and control group.Patients in both two groups were administered with enteral nutrition containing equal nitrogen and calorics for consecutively 7 days.In the glutamine group,patients were also supplied with oral glutamine (7.5g tid).Changes of plasma IgG,IgA,and IgM levels,percentages of T-lymphocyte subsets (CD3,CD4,CD8),and CD4/CD8 ratio were determined before and after treatment.Results Plasma IgG and IgA lev-els,percentages of CD3 and CD4,and CD4/CD8 ratio were significantly higher in glutamine group than in control group (P<0.05 or P<0.01).Conclusion Glutamine can improve the immune function in elderly patients with malnutritiop and promote their recovery.

The widespread use of antibiotics has been effectively controlled serious life-threatening infections.The trituration,exploitation and use of antibiotics has been rapidly developed and applied to many fields.Due to the extensive use of various antibiotics,the emergences of drug-resistant bacteria and the rates of bacterial resistance have increased unceasingly which has been a common focus in the world.Resistant pathogen can reduce the effectiveness of antibiotics,and which is a serious threat to human health.De-escalation therapy of antibiotics can quickly and effectively control serious infections,and avoid bacterial resistance,and induce fungal infections.The rational use of antibiotics in pediatrics is very imperative,which includes strengthening management of antibiotics,and improving awareness and vigilance of the adverse reactions of antibiotics,and consummating specification of medication.Then,realize the correct,safe,rational medication of antibiotics.

Since 1950s,the idea of liver transplantation (LT) was proposed,the technique of LT had been gradually and widely applied in the field of surgery.The development of LT experienced three stages,including animal experiment,clinical probation and clinical application.It is well known that LT is the only effective therapeutic method for terminal stage of liver diseases.In liver transplantation,the ischemia-reperfusion injury is difficult to avoid,and an important factor causing poor liver function.Meanwhile,hemodynamic volatility and internal environment disorder are important prognostic factors.How to reduce ischemia-reperfusion injury of the transplanted liver and improve intraoperative hemodynamic changes in liver transplantation is a clinical research focus.Recent studies has indicated that orthotopic liver transplantation retrograde perfusion method can effectively reduce the transplanted liver ischemia-reperfusion injury and improve liver function early after transplantation,and thus significantly improve the success rate of liver transplantation and survival.

BACKGROUND: Rat model of orthotopic liver transplantation is a very valuable model for experimental study in liver transplantation including organ preservation, tissue ischemia-reperfusion injury, allograft rejection and immune tolerance mechanism. Stable liver transplantation animal model is the basis of the related experimental studies. However, its experimental operation is long and boring, especially performed by a single operator under direct vision. OBJECTIVE: To investigate the operation techniques to establish a stable rat model of orthotopic liver transplantation by a single operator under direct vision. METHODS: The orthotopic liver transplantation was performed using two-cuff method in 50 pairs of rats. We exposed the abdominal cavity fully, perfused the donor liver through abdominal aorta without flipping donor liver; suprahepatic inferior vena cava was in vivo cut down using one-step method, without diaphragm ring; the suprahepatic inferior vena cava was anastomosed with single-row suture, and the cuff of portal vein was installed by fixing the blood vessel forceps on rubber. Hepatic artery was not reconstructed. Fluid replacement was administered to maintain hemodynamic stability in rats after operation. RESULTS AND CONCLUSION: The donor operative time was (36.2± 2.5) minutes, donor liver trimming time was (12.2± 1.5) minutes, receptor operative time was (45.6 ± 3.5) minutes, suprahepatic inferior vena cava anastomosis time was (10.1 ± 2.1) minutes, portal vein cuff time was (1.5 ±0.9) minutes, infrahepatic inferior vena cave cuff time was (1.1 ± 0.6) minutes, anhepatic phase was (15.1 ± 2.2) minutes. The success ratio of the operation was 100% and the survival rates within 1 week and 1 month were all 100%. It is indicated that the key factors of a successful model were stable anesthesia, good donor liver perfusion, adequate exposure, skilled microsurgical technology and vascular anastomosis technique.
