Objective By analyzing 2 560 echinococcosis cases through telemedicine,to explore a new mode for preventing,diagnosing,and treating of echinococcosis.Method From January 2009 to December 2013 in our hospital through remote medical care and consulting we analyzed cases and conducted statistics on consultation's person time,location difference,spectrum of disease and upward referral rate as well as the cost of hospitalization.Result (1) The amount of consultation rose from 182 cases in 2009 to 873 cases in 2013.(2) The proportion of consultation from northern Xinjiang is about 83％-91％,obviously higher than that from south Xinjiang and eastern Xinjiang,which fits those areas mainly with the economical character of the husbandry.(3) Most consultation cases are echinococcosis (99.42％) followed by echinococcosis (0.24％),pelvic cystic echinococcosis (0.19％),cerebral echinococcosis (0.12％),and cardiac echinococcosis (0.03％).(4) Upward referral rate is nearly 7.97％ and about 92.03％ patients were treated in local community hospitals saving medical care budget by RMB 14.78 million.Conclusions Use and establishment of the three level network system for preventing,diagnosing,and treating the echinococcosis by telemedicine effectively enhances primary hospital's ability in the care of these patients and alleviates patients economical burden.

Objective To compare the safety and effectiveness of three types of intrauterine device (IUD) inserted immediately after artificial abortion.Methods A randomized controlled clinical trial was performed in 4 family planning service stations in Pudong New Area from January to December 2012.Total 1 200 eligible women were randomly assigned to receive three types of IUD:MYCu,TCu380A or G-Cu200 (n =400 in each group) immediately after vacuum aspiration.All subjects were followed up for 12 months.The cumulative rates of termination of three IUD after 12 months were analyzed with WHO LTA 2.0 life table.Results Total 1 199 subjects were followed up for 12 months with a drop-out rate of 0.08％ (1/1 200).No any uterine perforation was found.During the 12 months the pregnancy rates with IUD in situ in MYCu,TCu380A and G-Cu200 groups were 0.26/100 women year,0 and 0.52/100 women year,respectively (x2 =1.951,P ≥ 0.2).The rates of expulsion in three groups were 0.26/100 women year,1.84/100 women year and 2.05/100 women year,respectively(x2 =5.539,P =0.066).The remove rates related to bleeding and paining in three groups were 1.26/100 women year,7.29/100 women year and 2.76/100 women year,respectively (x2 =21.625,P =0.001).The discontinuation rates related to IUD use in there groups were 3.25/100 women year,9.00/100 women year and 5.50/100 women year,respectively(x2 =12.191,P =0.004).The rates of Abnormal position in three groups were 1.51/100 women year,0 and 0.26/100 women year,respectively (x2 =8.649,P =0.014).Conclusion Three IUDs inserted immediately after vacuum aspiration are all effective.Among three IUDs,MYCu shows lower expulsion rate,lower discontinuation rate related to IUD use and higher continuous rate; but the abnormal position rate of MYCu is higher than other two types IUD.

A rapid method has been developed based on the sample preparation procedure named as QuEChERS (Quick,Easy,Cheap,Effective,Rugged and Safe),combined with reversed-phase high performance liquid chromatography with fluorescence detector and C18 column after precolumn derivatization using o-phthalaldehyde and 2-mercaptoethanol to determine dopamine in porcine muscle.Methanol and deionized water (0.1％ acetic acid,v/v) with a ratio of 60∶40 was used as mobile phase.The flow rate was 0.8 mL/min and dopamine was eluted within 15 min.The linearity range was 0.003-8 μg/mL with r=0.9992.The detection limit for dopamine was 4 μg/kg and the quantification limit was 9 μg/kg.Recovery studies were carried out at 0.1,0.5 and 1.0 mg/kg fortification levels and the average recoveries obtained ranged from 90.4％ to 98.2％ with relative standard deviations between 3.5％ and 8.1％.The method was found to be suitable for detection of dopamine in animal product tissues at the maximum residue level.

Objective Astrgaloside Ⅳ derivative (ASId) is one of Astragaloside Ⅳ (ASI) derivatives with higher water-solubility and may have more druggability than ASI. The present study aims at observing the effects of ASId on cardiovascular parameters in chronic heart failure in rats. Methods Using echocardiographic and haemodynamic measurements, the effects of ASId on congestive heart failure (CHF) induced by ligation of the left coronary artery in rats were investigated.ventricle (LV) pressure (dp/dt) in ASId treated groups were significantly increased. Both LV volumes in diastole and in systole were decreased significantly after ASId treatment, accompanied with a trend towards normalization of relative stress. ASId treatment also inhibited compensatory hypertrophy of depressed heart. Conclusion ASId could improve cardiac functions and inhibite compensatory hypertrophy and LV remodelling, which suggests the possibility of ASId as a new therapeutic drug for the treatment of CHF.

Objectiye To investigate the value of liver transplantation for the treatment of end-stage hepatic alveolar echinococcosis(HAE).Methods The clinical data of 8 patients with end-stage HAE who received liver transplantation at the First Affiliated Hospital of Xinjiang Medical University from December 2000 to August 2010 were retrospectively analyzed.The operation time,anhepatic phase,infusion of suspension of red blood cells and postoperative complications were observed.Results The median operation time,anhepatic phase and infusion of suspension of red blood cells were 635 minutes(range,490-760 minutes),66 minutes(range,44-240 minutes)and 20 U(range,4-40 U).Liver transplantation was successfully carried out on 7 patients except for 1 patient who received emergent liver transplantation died of severe hepatic encephalopathy,renal failure and coagulation disorder on postoperative day 1.The median follow-up time was 6 months(range,3-29 months).One patient died of septicopyemia in postoperative month 3,1 died of incurable infection of bile duct in postoperative month 5,and 1 died of acute rejection in postoperative month 6.One patient was complicated with stricture of the bile duct anastomosis,and was cured by choledochojejunostomy.The size of the metastatic lesion in the left lung of 1 patient was reduced.One patient who underwent liver autotransplantation had no signs of residual liver disease with good liver function.Conclusion End-stage HAE is an indication for liver transplantation.A minimum dose of immunosuppressive agent and systemic administration of anti-HAE drugs are necessary to prevent the recurrence of HAE and ensure a long-term survival.Liver autotransplantation is the optimal method for the treatment of end-stage HAE,because no immunosuppressive agent is needed after operation.

Objective To investigate the effect of echinococcus granulosus antigen B on the severity of streptozotocin induced diabetes mellitus.Methods Thirty male BALB/c mice were randomly divided into 3 groups:echinococcus granulosus antigen B group (group A,n =10),normal saline group (group B,n =10),control group (group C,n =10).Mouse in group A was injected by echinococcus granulosus antigen B and mouse in group B was given normal saline,Type 1 diabetes was induced.After 3 weeks,mice were executed and pancreases were scored on insulitis by HE staining.Serum IFN-γ and IL-4 levels were measured by ELISA.Results After 3 weeks of the establishment of diabetes model mouse body weight in group B and C decreased significantly compared with that in group A.Mouse mean blood glucose level in group A was significantly lower than that in group B and C.There were less than 40％ of islets with lymphocytic infiltration in group A,compared with 80％ in group B.The average Ridit was 0.423,0.519,and 0.561 in group A,B and C respectively,P ＜ 0.05.IL-4 level in group A was significantly higher than that in group B and group C [(71.6 ± 12.4) ng/ml,(12.6 ± 5.6) ng/ml,(14.2 ± 7.2) ng/ml,P ＜ 0.05].IFN-γ level in group B and group C were higher than that in group A [(276.1 ± 41.7) ng/ml,(352.2 ± 52.2) ng/ml,(358.1 ± 53.4) ng/ml,P ＜ 0.05].Conclusions Type 1 diabetes is organ specific T lymphocyte mediated autoimmune disease.Echinococcus granulosus antigen B has protective effects on diabetes mellitus in mice couteracting autoimmune injury to the islets by streptozotocin,probably by a mechanism related to immune deviation of Th1 to Th2.

Ex-vivo liver resection and liver autotransplantation offers a chance to cure extensive regional liver diseases which are otherwise deemed untreatable in selected cases. A 33-year-old male patient with advanced alveolar echinococcosis (AE) which invaded the right lobes and adjacent retrohepatic inferior vena cava, while the left lobes were free from lesion and had proliferated to over 1200 ml in size except for a 1 cm × 1 cm solid lesion in the segment Ⅳ. No extrahepatic metastases were found in this patient. A lesion with a size of 4300 ml and other small lesions in the right lobes were removed extracorporeally,and the retrohepatic vena cava was repaired, then the remaining AE-free left lobes (more than 700 ml in size) and the retrohepatic inferior vena cava were re-implanted in situ. A temporary end-to-end cavo-caval shunt with interposition of a blood vessel prosthesis and end-to-side portocaval shunt were established to keep the blood flow during the four-hour anhepatic phase. The patient was followed up for six months, and he had no signs of residual liver disease with good hepatic function.
