Clinical data of 150 patients with mild and 38 patients with severe confirmed influenza A/H1N1 were collected and retrospectively analyzed in this paper with descriptive epidemiology. Mild patients mainly presented with symptoms similar to seasonal influenza with few complications, however,persistent high fever, cough with bloody sputum expectoration, chest distress and short of breath manifested in severe patients with respiratory failure and acute respiratory distress syndrome in some cases. Proportion of obesity and underlying diseases in severe patients, who were at high risk for severe influenza A/H1N1, was higher than that in mild ones (P<0. 05). Average course of the illness spanned five to 11 days in patient with mild influenza A/H1N1 with all cured, and 34 of severe cases discharged with better recovery and other four died with a case-fatality of 10. 5 percent.

-6.00D), selected randomly and consecutively, were examined by ICGA and FFA synchronically.ResultsThe result of early phase of FFA showed hypofluorescence of the background in 25 eyes,while of late phase showed subretinal neovascularization (SRNV) in 10 eyes and streak formation in 40 eyes. The result of ICGA showed choroidal retrobulbar arteries in 8 eyes, hypofluorescence of the background in 35 eyes, SRNV in 8 eyes, and streak formation in 52 eyes.ConclusionThe iconographic characteristics of ICGA and FFA of high myopia include hypofluorescence of the background, SRNV and streak formation. ICGA can give more exact information on the lesions of choroid in high myopia. The synchronic examination of ICGA and FFA may act as a guide to the therapy for high myopia.

ObjectiveTo investigate the effects of ligustrazine on renal tubulointerstitial injury in adriamycin nephrosis rats and its mechanism.MethodsForty male Sprague-Dawley rats were randomly divided into sham-operation group,model group,ligustrazine group and Benazepril group.The rat nephropathy model was established by adriamycin injection and unilateral nephrectomy.The 24-hour urinary protein excretion at the start,2nd,4th,6th weekends was analyzed.All rats were sacrificed at the 6th weekend,and then the renal function and the tubulointerstitial pathological injury were examined.Immunohistochemistry was used to measure the expression of ET-1.ResultsThe 24-hour urinary protein excretion [ (30.07 ±2.12) mg/24 h,(201.83 ± 8.63 ) mg/24 h,( 470.70 ± 58.79 ) mg/24 h ] ( at the 2th,4th,6th weekend),blood urea nitrogen[ BUN( 20.20 ± 2.65 ) mmol/L],serum creatinine[ Scr ( 86.79 ± 2.20 ) μmol/L),tubulointerstitial pathological injury (4.38 ± 0.26) and the expression of ET-1 ( 126.92 ± 3.63 )in model group were significantly higher than those in sham-operation group [ ( 6.75 ± 2.07 ) mg/24 h,( 8.28 ± 0.71 ) mg/24h,( 25.37 ± 4.30) mg/24 h,( 8.93 ± 1.05 ) mmol/L,(49.00 ± 5.34 ) μmol/L,1.06 ± 0.19,32.09 ± 3.71,P < 0.01 ].Compared with model group,the 24-hour urinary protein excretion [ ( 176.93 ± 9.20)mg/24 h,( 270.45 ± 60.21 ) mg/24 h) ( at the 4th,6th weekend),BUN [ ( 13.75 ± 2.60 ) mmol/L ],Scr [ ( 62.49 ±3.29)μmol/ L ],Renal tubulointerstitial pathological injury (2.78 ± 0.10) and the expression of ET-1(57.44 ± 4.98 ) were significantly decreased in ligustrazine group( P < 0.01 ).ConclusionsLigustrazine can downregulate the expression of ET-1 and decreased urinary protein excretion,leading to reduce tubulointerstitial inflammation and fibrosis.

To explore the major risk factors for hepatitis B (HBV) in Shanghai Jinshan district.A one-to-two matched case control study was performed among the residents of Shanghai Jinshan district in 2010.The data were analyzed by single factor and multivariate analysis performed with SAS 9.13.Single factor analysis showed that the risk factors for hepatitis B were family member with hepatitis B,no vaccination history of hepatitis B virus vaccine and oral treatment.Muhivariable analysis showed that family member with hepatitis B (OR =1.91),no vaccination history of HBV vaccine (OR =0.49) and oral treatment (OR =2.06) were independent risk factors for HBV infection in Shanghai Jinshan district.Strengthening health education for HBV prevention,modifying unhealthy living habits and standardizing the treatment of oral diseases are important measures for lowering infectious rate of HBV.

Objective To evaluate the therapeutic effect of abdominal multiple visceral organ transplantation for hepatic cirrhosis combined with diabetes by using donation after cardiac death (DCD).Methods Two patients suffering from hepatitis B-related liver cirrhosis,hepatocellular carcinoma combined with insulin dependent type 2 diabetes mellitus were given multiple visceral organ transplantation from May to June 2012.The transplanted organs including the liver,pancreas and duodenum were obtained from two donors after cardiac death which accorded with C-Ⅲ criteria.The donor internal and external iliac arteries were anastomosed to celiac axis and superior mesenteric artery and then the donor arteria iliaca communis was anastomosed to recipient abdominal aorta.The portal vein reconstruction was performed by end-to-side anastomosis between the donor and recipient portal vein.The pancreatic juice drainage was achieved by side to side anastomosis between donor duodenum and recipient jejunum.The pancreases of recipients were retained.Results The alanine aminotransferase,aspartate aminotransferase and total bilirubin of two patients were recovered to normal level at 2nd week after operation.The blood glucose and serum amylase returned to normal levels at 7th d and 4th d respectively.The fasting serum C-peptide and insulin were also at normal level at 2nd week.One patient with local intestinal anastomotic fistula was given percutaneous puncture drainage for four weeks and recovered.One patient recovered smoothly one month after transplantation without surgical complications.Conclusion Abdominal multiple visceral organ transplantation is an effective treatment for hepatic cirrhosis combined with diabetes by using DCD donor.

Objective To explore the feasibility and safety of cotransplantation of autologous bone marrow-derived mesenehymal stem cells (MSCs) and peripheral blood stem cells in hematological malignant diseases and to observe its effect on hematopoietic reconstruction after cotransplantation. Methods Adult human MSCs were isolated from the healthy bone marrow of the patient himself with Percoll (1. 073 g/ml) and cultured in Dulbecco's modified Eagle's medium with low glucose containing 10% AB type human serum. After conditioning regimen of high-dose chemotherapy and radiotherapy, cotransplantation of autologous bone marrow-derived MSCs and peripheral blood stem cells was done in five patients with hematological malignant diseases. Results The process of the infusion was safe and there were no adverse reactions or other toxicities related to the infustion of MSCs. The median time to achieve neutrophil counts greater than 0. 5 × 109/L was 9.4 days ( ranging from 8 to 11 days) after cotransplantation and platelet counts greater than 20 × 109/L 12. 2 days (ranging from 10 to 14 days). Conclusion Cotransplantation of autologous bone marrow-derived MSCs and peripheral blood stem cells in hematological malignant diseases is feasible and safe. The rapid hematopoietic reconstruction after cotransplantation shows that MSCs have an effect on hematopeiesis, but the mechanism is still to be investigated.

Objective The clinical effect of the lateral femoral cutaneous artery flap for soft tissue defects of leg wounds. Methods From October 2007 to January 2016, VSD was firstly used to promote the growth of granulation tissue. When the growth of granulation tissue became satisfactory, flaps were designed based on the anatomical characteristics of the lateral femoral cutaneous artery. We repaired 20 cases of wound defects by cutting flaps that coincide with the recipient vessels. Result 20 cases were followed up for 6 to 24 months, 12 months on average. All flaps were survived and only one case had small area of necrosis flap which was healed by replacing medicines. In all cases, wounds were healed and flaps showed good color and good texture. The strength of quadriceps muscle was good and the extension of knee flexion was 0° to 150°. Conclusion To The lateral femoral cutaneous artery flap is used for soft tissue defects of refractory wounds on leg , flap donor sites are sutured directly, the treatment period is shorten and the method is safe and effective. The lateral femoral cutaneous artery flap is one of ideal choices for wound tissue defects.
