Objective · To compare the short and medium-term efficiency and safety of 1470 nm laser with foam sclerotherapy with ligation of great saphenous vein and 808 nm laser with foam sclerotherapy to treat varicose veins of lower extremity. Methods · Seventy-seven hospitalized patients patients and twenty-one day-surgery patients were retrospectively analyzed. Results · There was no obvious difference in the closure of great saphenous vein for short to medium-term efficiency between the day-surgery group and hospitalized group. The postoperative complications and recurrence rate of day-surgery group was not higher than that of the hospitalized group, but the degree of perioperative comfort, economic cost and the time returning to normal life of day-surgery group were superior to that of the hospitalized group. Conclusion · 1470 nm laser with foam sclerotherapy with ligation of great saphenous vein and 808 nm laser with foam sclerotherapy to treat varicose veins of lower extremity had similar clinical effect, but the degree of safety and comfort was higher and trauma was less. The day surgery with 1470 nm laser to treat varicose vein of lower extremity could also simplify the procedure of hospitalization and reduce the cost of health care, which could be a new option for patients.

Two patients underwent liver transplantation of blood type incompatibility were collected from Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA. Case 1: A male who had primary hepatic carcinoma underwent classic orthotopic liver transplantation; the blood of donor was type A, and the blood of recipient was type O. Case 2: A female having history of type B hepatitis underwent classic orthotopic liver transplantation due to pregnancy combining with severe liver disease and coagulation disorder; the blood of donor was type B, and the blood of recipient was type O. Immunohistochemistry staining was used to observe pathological changes and deposition of various immunoglobulin and complement in two cases following liver transplantation of blood type incompatibility under optic microscope and to investigate diagnostic standard of humoral rejection. The results showed that linear or granular depositions of IgG, IgM, IgA, C4c, C4d, and Clq were found in endothelial cells of hepatic sinusoid, suggesting that IgG and other immunoglobulin exhibited a strongly positively diffused deposition on the endothelial cells of hepatic sinusoid, while expression of C4d and other complements was also found. All those mentioned above could be considered as evidences to prove onset of humoral rejection in transplanted liver tissue.

Objective To compare the clinical outcomes between two different femur rotating osteotomy methods for kneeling ability recovery after total knee arthroplasty (TKA).Methods From January 2012 to December 2014,88 patients underwent TKA were selected for a retrospective study and were divided into two groups based on the methods to determine femoral rotation.Forty-eight patients were in measured resection group,while 40 patients in gap balancing group.The patients in both groups underwent fixed-bearing tibia prosthesis.There were no statistical significance between the two groups in gender,age,BMI and knee varus angle (P＞0.05).The knee varus angle,ROM,Oxford knee score (OKS) and American Knee Society (KSS) knee score were collected to assess malformation correction,kneeling ability and functions at pre-operation,one and two years postoperatively.Results The operation duration and blood loss in measured resection group were 80±19 min and 348±121 ml,while these data in gap balancing group were 82±23 min and 315 ± 100 ml respectively (P＞0.05).Patients in measured resection group were followed up 24-59 months (mean 43± 11 months),while the followed-up duration in gap balancing group was 25-58 months (mean 47±10 months).No major complications such as infection loosen and instability were occurred.Varus angles in measured resection group at postoperative 1 year and 2 year postoperative were 1.2°±0.4° and 1.0°±0.2° respectively,while those in gap balancing group were 0.9°±0.2° and 0.8°±0.3° (P＞0.05).The scores of the seventh item of OKS in measured resection group at 1 year and 2year follow-ups were 2.79±1.02 and 2.75± 1.03 respectively,while those in the gap balancing group were 1.90±0.85 and 1.80±0.83 (P＜0.01).ROM in the measured resection group at 1 year and 2 year postoperative were 102.08°± 15.60° and 102.08°±15.60° respectively,while those in the gap balancing group were 112.50°±18.32° and 113.00°±18.09° (P＜0.05).KSS in measured resection group at postoperative 1 year and 2 years were 154.63±31.12 and 154.63±31.26 respectively,while those in the gap balancing group were 170.55±22.67 and 173.45±22.52 (P＜0.05).Conclusion The method of measured resection and gap balancing to confirm femoral rotation during TKA can both achieve favorable kneeling ability and clinical outcomes,while gap balancing show superiority on kneeling ability recovery,ROM and clinical outcomes at 2-year postoperative improvement.

OBJECTIVE:To provide reference for prescriptions audit before payment in hospital pharmacy. METHODS:The management measures of prescriptions audit and intervention before payment in our hospital were introduced. 1 200 outpatient pre-scriptions within 1 year before and after management were subjected to a statistical analysis. The effects of prescriptions audit be-fore payment were evaluated through analyzing and comparing qualification rate of prescription and unqualified prescriptions. RE-SULTS:Our hospital adopted a series of measure to realize prescriptions audit and intervention before payment by clinical pharma-cists,such as using information audit system,formulating audit standard,educating pharmacists,establishing audit job system, prescriptions review and feedback system,setting up communication system,etc. Of the total audited 189 665 prescriptions, 14 581(7.69%)failed to audit and 606 prescriptions hadn’t been revised after 1 year management,with effective intervention rate of 95.84%. Compared with before management,the prescription qualification rate increased from 88.83% to 98.67% after manage-ment(P<0.01). The quantity of overdose,inconformity with medical insurance,overload and other conditions reduced to 0. CON-CLUSIONS:It is feasible for pharmacists to audit and intervent prescriptions before payment in hospital pharmacy to improve pre-scription qualification and promote rational drug use in the clinic.

Objective To investigate the regulation effect of hepatocyte nuclear factor (HNF) 1α on the gene expression profile and the signal pathways in HuH7 cells.Methods The expression of HNF1α was increased or decreased in HuH7 cells by Lenti-virus carrying HNF1α or shHNF1α.The expression profile of the cells after treated was examined by microarray technology.The difference expressed gene regulated by HNF1α were screened and the pathway was analyzed with DAVID software and related analysis system.The regulation effect of HNF1α on transforming growth factor (TGF)β signal pathway was detected by reporter gene test and the regulation role of HNF1α on related genes of TGFβ signal pathway was determined by real-time polymerase chain reaction (PCR) and Western blotting assay.Results The expression of HNF1α in HuH7 cells was significantly up-regulated by Lenti-virus carrying HNF1α gene (Lenti-HNF1α) and which was down regulated by Lenti-virus with shHNF1α gene (LentishHNF1 α).Expression profile analysis revealed that 339 genes were positively up regulated two times by HNF1α and 325 genes were negatively down regulated two times.Signal pathway analysis revealed that HNF1α regulated drug metabolism,biosynthesis of unsaturated fatty acids and glycolysis/gluconeogenesis metabolism signal pathways.Moreover,it also involved in the regulation of TGFβ、nuclear factor (NF)-κB and p53 tumor-related signal pathways.Furthermore,Luciferase reportor gene experiment indicated that up-regulated HNF1α could inhibit the activation of TGFβ signal pathway.And the results of real-time PCR and Western blotting verified that up-regulated HNF1α could inhibit TGFβ signal pathway related gene c-myc and TGFβ1 and then inhibited the activation of TGFβ signal pathway.Conclusion HNF1α broadly affects the gene expression profile and the tumor genesis and development related signal pathways in HuH7 cells,furthermore,HNF1α can inhibit the activation of TGFβ signal pathway.
