Objective:To compare the clinical effects of different reconstructive alimentary canal for total gastrectomy.Methods: The patients were divided into P loop/Roux-en-Y and Distal antiperistaltic jejunal reservoir group.The nutritional status of these two groups was investigated.Results:The differences of body weight,hemoglobin,total albumin and albumin afer operation one year in P loop group were(52.5?3.8)kg,(98.0?6)g/L,(52.0?2)g/L,(28.0?3g)/L;meanwhile those in Distal group were(59.2?4.8)kg,(121.0?5)g/L,(62.0?4)g/L,(35.4?2)g/L.These differences between two groups were significant(P

Objective To develop a high-speed data acquisition system with sampling frequency of 2 GHz to meet the requirement of accurate measurement of flight time.Methods The ALTERA STRATIX Ⅲ series FPGA was used as the main control chip, matching with high-performance ADC chip with sampling frequency up to 2 GHz and sampling accuracy up to 12 bit, while extending 512 MB DDR3 SDRAM for data cache and exchanging data with the host computer through Gigabit Ethernet.In addition, a variety of PCB wiring methods were used to effectively ensure the signal integrity.Results The 250 MHz sine signal was input into the data acquisition board with 2 GHz sampling frequency,by analyzing and calculating the sampling data,acquired the following performance index of SNR=44.6639 and ENOB=7.1.Conclusion This high-speed data acquisition system based on ADC technology is a fast and reliable path and method for the measurement and analysis of biological mass spectrometry data.

Objective To compare the different operation routes of laparoscopic right hemicolectomy (up‐to‐down vs.medial‐to‐lateral dissection sequences ).Methods In total ,56 cases enrolled in the Central Hospital of Wuhan between Janu‐ary 2013 and January 2014 were randomly divided into the up‐to‐down group and medial‐to‐lateral group.Statistical data in terms of general information ,operation time ,blood loss ,rate of conversion to open surgery ,number of lymph nodes harvested , postoperative complications ,time to first bowel movement and hospital stay time were compared and analyzed.Results The up‐to‐down group has the advantages of shorter operation time [(128.24 ± 21.14) min vs.(166.45 ± 30.23) min ,P<0.01] ,lower conversion rate(0% vs.7.14% ,P=0.035)and less blood loss= [(45.67 ± 10.66) mL vs.(78.45 ± 40.28) mL ,P<0.01] than the medial‐to‐lateral group.However ,there were no significant differences in terms of general information ,number of lymph nodes harvested ,rate of postoperative complications ,time to first bowel movement and hospital stay time (all P>0.05) .Conclu‐sion Taking the superiority of broad perspective ,clear image ,safety and less blood loss into consideration ,the up‐to‐down op‐eration route of laparoscopic right hemicolectomy deserves clinical recommendation.

Bone marrow mesenchymal stem cells (MSC) are the non-hematopoietic cellular component in the bone marrow that have multiple differentiation potency. MSC play a key role in the regulation of bone marrow hematopoietic niche and modulation of immune function through various mechanisms. They are currently recognized as a promising cell source in tissue engineering, a vehicle in gene therapy and a powerful tool in the management of graft-versus-host disease after allogeneic stem cell transplantation. In this review some momentous aspects regarding the current status and potential clinical applications of MSC in hematopoietic stem cell transplantation, aplastic anemia and multiple myeloma were summarized.

Objective To evaluate the application of operations of preserving spleen in the treatment of splenic injury. Methods Serial operations of preserving spleen were performed in 78 cases in the past 10 years. 18 treated with simple splenorrhaphy,15 with ligation of splenic artery and splenorrhaphy, 13 with partial splenectomy,and 32 treated with autoplasty of spleen. Results All the cases were cured with satisfactory followed-up results.Conclusion The operation of preserving spleen for splenic injury is safe and feasible.

Objective:To evaluate the utilization of antifungal drugs in Nanjing area, and provide clinical reference for the rational use of antifungal drugs. Methods:According to the sales data of antifungal drugs in 34 hospitals in Nanjing area from 2013 to 2015, the utilization of antifungal drugs was analyzed in respects of consumption sum, DDDs and DDC. Results:The consumption sum and use of antifungal drugs increased year by year. The maximum amount of consumption sum growth rate was 41. 13%. Triazole drugs oc-cupied the top of consumption sum during the past three years, and the sales amount accounted for more than 60% of all. In term of consumption sum, voriconazole, fluconazole, itraconazole and caspofungin ranked top 4 of antifungal drugs. Clotrimazole topical prepa-rations and oral itraconazole ranked top 2 of DDDs, and caspofungin, micafungin and voriconazole ranked top 3 of DDC. Conclusion:The clinical application of antifungal drugs continues to increase during 2013 and 2015. Invasive fungal infection is a lethal factor at high risk. Choosing reasonable, effective, safe and economic of antifungal drugs is the first principle in clinical treatment.

ObjectiveTo investigate the therapeutic effects of advanced lung adenocarcinoma treated with TCM treatment based on syndrome differentiation combined with Gefitinib.MethodsAll cases were recruited from adenocarcinoma of lung patients in Hunan Province Cancer Hospital from February 2008 to February 2010.These 56 adenocarcinoma of lung patients were randomly divided into a treatment group (30cases) and a control group (26 cases).The control group was treated with Gefitinib,250 mg/d,until the disease getting progress or the patient showing intolerable untoward reaction; while the treatment group was treated with TCM syndrome differentiation based on the control group.ResultsAfter the treatment,the total therapeutic effects was 90.00％ in the treatment group than 65.38％ in the control group (x2=5.40,P＜0.05); symptoms score in both group decreased after the treatment,comparing with the same group before the treatment,with the difference was statistical significance (tthe treatment group=9.2446,tthe control group=2.7778,both P＜0.01) ;non-progressive survival rate of half year,1year and 2year was 66.67％,50.00％ and 30.00％ respectively,and survival rate of lyear and 2yenr was 73.33％ and 46.67％ respectively,in the treatment group,while non-progressive survival rate of half year,lyear and 2year was 38.46％,23.08％ and 7.69％ respectively,and survival rate of 1year and 2year was 46.15％ and 19.23％ respectively,in the control group,showing statistical difference between the two groups (x2 value was 4.46、4.31、5.44、4.31、5.27,P value was 0.03、0.04、0.02、0.04、0.02,all P＜0.05 ) ; the effective power of KPS was 76.67％ and 46.15％ in the treatment and the control group respectively,showing statistical difference(x2=6.24,P＜0.05) ; both groups were absent of such side effects of hematology,heart,liver and kidney toxicity,and interstitial pneumonia,but the incidence rate of Ⅱ ～ Ⅲ degree rash and diarrhea was significantly decreased in the treatment group,comparing with the control group(x2=4.49、4.37,P＜0.05 ).ConclusionThe therapy of TCM treatment based on syndrome differentiation combined with Gefitinib can improve living quality,control aggravation of disease,prolong life span and enhance survival rate of the patients with advanced lung adenocarcinoma.
