Objective To explore the significance of mediastinum drainage tube in prevention and treatment of intrathoracic anastomotic leak after esophagectomy. Methods The morbidity and prognosis of intrathoracic anas-tomotic leak after esophagectomy in 180 patients with esophageal or cardia carcinoma (group A) who used mediasti-num drainage tube in operation from 2006 to 2008 was studied retrospectively,and were compare with 154 patients (group B) without mediastinum drainage tube from 2004 to 2006. Results The morbidity of intrathoracic anasto-motic leak after esophagectomy was 1.67% (3/180) in group A,and 4.55% (7/154) in group B,but no difference between them(χ2=1.4807, P>0.05) were found. Compared to group B, the final diagnosis of anastomotic leak in group A was early [(6.7±0.6) vs (10.0±2.1) days after operation (t=2.62, P<0.05)] and the duration of fe-ver was short [(5.3±1.5)vs (43.0±20.9) hours (t=4.39, P<0.01)]. The prognosis of 3 cases in group A was well, who all recovered without operation and had shorten hospital days than group B [(23.7±5.9)d vs (45.3± 5.0)d,t=4.86,P<0.01)]. In 7 cases of group B,there were 5 cases underwent second operation,but only 3 cases recovered, the case fatality rate was 2.60% (4/154), higher than in group A (0, Fisher, P<0.05). Conclusions Although the mediastinum drainage tube used or not used in esophagectomy is unrelated with the occurrence of anas-tomotic leak, and the significance to use it is that it can help to discover anastomotic leak early, and control mediasti-num infection effectively without reoperation,and improve patients' prognosis.

Objective:To investigate the effects of rosuvastatin and lfuvastatin on patients with acute coronary syndrome (ACS) combing impaired glucose tolerance (IGT).
Methods: A total of 215 consecutive ACS patients combing IGT treated in our hospital from 2009-05 to 2011-05 were studied. The patients were randomly divided into 2 groups, Rosuvastatin group, the patients received rosuvastatin10mg/day, n=108 and Fluvastatin group, the patients received fluvastatin 40mg/day, n=107. The total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) levels before and at 6, 12, 24 months after medication, fasting blood glucose (FBG), 2-hour postprandial glucose (2hPBG) and the number of new-onset of diabetes patients were compared between 2 groups.
Results: After treatment, the TC, LDL-C levels were decreased (6, 12, 24 months) and the HDL-C level (12, 24 months), 2hPBG (24 months) were increased in both groups. Compared with Fluvastatin group, Rosuvastatin group had decreased TC and LDL-C (6, 12, 24 months), and increased LDL-C (24 months). With 6, 12, 24 months treatment, the blood lipids reached the standard were more in Rosuvastatin group than those in Fluvastatin group as 35.3%vs 26.1%, 36.4% vs 22.0%, 43.1% vs 31.8% respectively, all P<0.05. With 12 and 24 months treatment, the new-onset diabetes patients in Rosuvastatin group were 11 and 18, in Fluvastatin group were 12 and 17. With 12, 24 months treatment, FBG, 2hPBG levels and the number of new-onset diabetes patients were similar between 2 groups, P>0.05.
Conclusion: Compared with lfuvastatin, the conventional dose of rosuvastatin could better reduce the blood lipids level in ACS patients combing IGT, the effects for preventing ACS patients from IGT to diabetes were similar for both drugs.

To determine the diagnostic efficiency of parallel detection of the circulating antigens and antibodies in schistosomiasis, sandwich ELISA and indirect ELISA by using the labeled McAb JPG3 were used to detect the presence of the circulating antigens and the circulating IgG antibodies in serum samples from different kinds of population. and then the sensitivity and specificity of this method of testing as well as the efficiency of the application of this method in heavy endemic area. were determined in comparison with serial test. It was found that the sensitivity and specificity of the parallel test were 97.9% and 92.2% , however, those of the serial test were 76.0% and 99.2% respectively. The positive rates of parallel test and serial test to detect the stool examination-positive for schistosoma eggs in population of the endemic area were 94.6% (35/37) and 67.6% (25/37), while those to detect the stool examination-negative for schitosoma eggs were 69.8% (97/139) and 39.6% (55/139) respectively. It is apparent the parallel test for the detection circulating antigens and antibodies in schistosomiasis shows its high diagnostic efficiency, especially in the heavy endemic area of schitosomiasis.

Objective To evaluate the feasibility,safety and efficacy of tubeless percutaneous nephrolithotomy ( PCNL).Methods Patients who underwent PCNL were randomized into 2 groups by extracting a random number generated from random number table,tubeless PCNL group and traditional PCNL group when the stones were cleared.Each patient in tubeless PCNL group was treated with insertion of a F5 ureteral double pigtail stent without placement of nephrostomy tube,while both double pigtail stent and F16 nephrostomy tube were placed in patients in traditional PCNL group.Exclusion criteria were severe bleeding requiring blood transfusion,stone residual requring a second PCNL,severe hydronephrosis with the thickness of renal parenchyma less than 5 mm,pyonephrosis,stricture of ureter or ureteropelvic junction,and severe perforation of the collecting system.A total of 50 patients were enrolled in this study.Tubeless PCNL and traditional PNCL were performed in 25 patients,including 27 kidney units,respectively.The two groups had comparable demographic data.All the operations were performed by the same surgeon.Evaluation factors included postoperative pain,decreased hemoglobin,blood transfusion rate,incidence of fever and perirenal hematoma,and duration of hospitalization.Results The average visual analogue scale (VAS) score on postoperative day 1 in tubeless PCNL group was 2.24 compared with 5.04 in traditional PCNL group (P ＜ 0.01 ).The average hospital stay in tubeless PC NL group (3.04 d) was significantly shorter than that in traditioal PCNL group (6.88 d) (P ＜0.01 ).The differences in average hemoglobin drop and stone clearance in the 2 groups were not significant.The differences between the 2 groups in blood transfusion ( 1/25 in tubeless PCNL group vs 3/25 in traditional PCNL group,P ＞0.05),renal hematomas rate (6/27 in tubeless PCNL group vs 7/27 in traditional PCNL group,P ＞ 0.05) and fever rate (3/25 in tubeless PCNL group vs 4/25 in traditional PCNL group,P ＞0.05 ) were not significant.There was no incidence of urinary leakage from the nephrostomy site in the 2 groups.Conclusions Tubeless PCNL can significantly decrease postoperative pain and discomfort and shorten the duration of hospitalization without increase of complications.Tubeless PCNL is safe,effective and performable,but the contraindications such as massive haemorrhage,pyonephrosis,ureteral obstruction,severe perforation of the collecting system,residual stone requring a second PCNL,should be kept in mind.

Objective　To investigate the diagnosis and treatment of acute rejection of orthotopic liver transplantation (OLT). Methods　From July 1999 to April 2000, two piggyback liver transplantations were performed on two patients with Wilson's disease. Results　Cyclosporine A, azathioprine and methylprednisolone were the baseline immunosuppression management. Acute rejection occured 5 times in the 2 patients. The correct diagnosis was obtained through clinical inspection, liver function test and biopsy. The rejections were controlled by intensive steriod therapy plus OKT3 or FK506. Conclusions　Clinical inspection and liver function test can suggest the episode of acute rejection in time. Hepatic biopsy is the key point for diagnosis of acute rejecton, Reasonable use of immunosppression is critical for the treatment.

Objective To understand the characteristics of schistosome cercarial infested water contact of residents in Poyang Lake endemic areas after the operation of Three Gorges Project,so as to provide the evidence for formulating a well-directed con-trol strategy. Methods The residents in two villages in schistosomiasis endemic areas were selected and surveyed for their activi-ties of infested water contacts by questionnaire. Results The proportion and frequency of infested water contacts of residents in Poyang Lake region were high and the average rate of infested water contacts was 69.77%,and 98.96%of infested water contacts occurred in spring,summer and autumn. The main ways of infested water contacts were fishing/swimming/playing for adult men, washing clothes/fishing for adult women,and swimming/playing for school children,respectively. The rates of infested water con-tacts were 73.33%,71.63%and 61.87%in adult men,women and school children,respectively. The frequencies of infested water contacts>1 time/week,1 time/week-1 time/month,and<1 time/month were 62.61%,23.74%and 13.66%respectively. Conclu-sions The infested water contacts mainly occurs in spring,summer and autumn,and the main way of infested water contacts was fishing. Farming and mowing grass,which had been the primary way,now become the secondary way for the adult residents.

Objective To determine whether homocysteine(Hcy)and monosodium glutamate (MSG)could lead to animal model of hypertensive disorder complicating pregnancy and its mechanism. Methods Female adult Wistar rats were randomly divided into 4 groups:pregnant control group(PN), pregnant Hcy group(PH),pregnant glutamic acid group(PG)and pregnant Hcy and glutamie acid group (PHG).The rats of each group were injected with Hey 200 mg/kg or physiological saline every day intraperitoneally and with MSG or 0.9% saline every other day via Hcy injection from the 10th day to the 20th day of pregnancy.The blood pressure,urine protein,function of liver and kidney,weight of placenta, length and weight of fetus were all measured.The histological change of the pallium and the change of behavior of pregnant rats were also observed.Results(1)The blood pressure in PH[(107?8)mm Hg, 1 mm Hg=0.133 kPa],and PHG group [(109?10)mm Hg] after the treatment increased significantly compared with those in other groups from the 12 th day after pregnancy(P

Objective To evaluate the function of MRE11 in inflammasome activation.Methods Different stimuli,in-cluding Poly(I∶C), Poly(dA∶dT),E.coli gDNA,293T gDNA,CPPD and HSV,were used to identify the effective inflamma-some activator using ELISA.Then, MRE11 siRNA oligos were sythesized and transfected into THP-1 cells while Western blotting was used to analyze the efficacy of MRE 11 knockdown .Finally ELISA and Western blotting were used to analyze the involvement of MRE11 in inflammasome activation induced by Poly (I∶C), Poly(dA∶dT), E.coli gDNA and 293T gDNA. Results The IL-1βsecretion and pro-caspase-1 activation which induced by Poly ( I∶C) , Poly( dA∶dT) , E.coli gDNA and 293T gDNA were reduced with different degrees in MRE 11-knockdown THP-1 cells.Conclusion These results indicate that MRE11 is required for inflammasome activation induced by genetic materials .

Objective To understand the current prevalence of clonorchiasis in Jiangxi Province. Methods A survey was performed according to the scheme of the 3rd Principal Human Parasites of Jiangxi Province. Based on the ecological regions,a stratified cluster sampling method was applied by the economic and geographic situation. In rural areas,the investigation of C. si?nensis was carried out together with the soil?transmitted helminths investigation,and in the urban areas,the random cluster sam?pling method was applied for the C. sinensis investigation. There were 92 survey sites from 32 counties. The eggs of C. sinensis in stool were examined by Kato?Katz technique,and health knowledge was also investigated by questionnaires in some people at the same time. Results A total of 23 606 sample residents were investigated,and 138 were found infected with C. sinensis, with the infection rate of 0.58%. Light infection was found in most of them. Totally 124 C. sinensis infected persons focused in Xinfeng County,and only a few of infected people scattered in the other counties. In Xinfeng County,851 residents were investi?gated. Among them,the infected people were found in all the age groups except the 0?year age group. The highest infection rate appeared in the 70? years group(24.00%). The male infection rate was 20.29%,which was higher than that of the female (6.25%),showing a statistically significant difference(P<0.01). The infection rate was highest in the population who received high school or technical secondary school education(31.48%). For the occupation distribution,the infection rate was highest in public officers(39.39%). The questionnaire survey showed that the infection rate in the populations in Xinfeng County who had the history of eating raw fish or raw shrimp was 33.15%. Conclusions The distribution of C. sinensis infection presents a region?al aggregation in Xinfeng County,but in other areas,the distribution is sporadic. It is necessary to continue to carry out the para?sitic disease screening,and in Xinfeng County,it is necessary to strengthen the comprehensive prevention and control interven?tion.
