Studies on the variation of amylase, lipase and lrotease activity of Whitmania pigra in 0-6 months old using 3, 5-dinitro- salicylic acid colorimetry, right-nitrophenyl palmitate ester (ρ-NPP) colorimetry and folin-phenol method. The results showed that pro- tease activity remained low before 1.5 months old and with the highest activity in 2 months old, but after showing a small peak in 4 months, alkaline protease rapid declined. Amylase was low at born, then gradually increased the activity of the highest in 2.5 months old. Lipase with a strong vitality at birth, then 1 month with minimum and 2 months peaked, but appeared a small peak in 4 months old. In summary, only lipase exhibits strong activity at birth, lipase with the strongest activity in the digestive tract during develop- ment. Protease, lipase and amylase with the strongest activity at 2-3 months old, but were decreased after 4 months old.

Objective The incidence of post-operative hyperbilimbinemia, which is associated with poor outcomes in patients, was reported to be increased in recent years though it has been a rare complication for cardiac operations. Post-opera-tive impairment of liver function is highlighted. We evaluated the incidence and prognosis of post-operative hyperbiliruhinemia in adult patients who underwent cardiotomy with extracorporeal membrane oxygenation (ECMO) support. Methods Sixty-five adult patients who had received ECMO support after cardiac surgery from 2004 to 2008 were enrolled and evaluated retrospec-tively. Post-oporative hypethilirubinemia was defined as the serum level of the total bilirubin more than 51.3 μmol/L during postoperative period. Demographic and clinical data included gender, age, types of surgery, perioperative hemodynamic param-eters, biochemical variables, duration of the ventilation support, ICU stay and outcomes. Results The mean age of the pa-tients was (50.1 ± 13.9) years, forty-six patients(70.8%) were male. The main cardiac procedures were heart transplanta-tion for 9 patients, coronary artery bypass grafting and/or valve operations for 47 patients, congenital heart disease correction for 4 patients and other operations for 5 patients. Among all patients, fifty-one patients(78.5%) were weaned from ECMO succeas-fully and thirty-thrce patients were discharged from hospital. The overall mortality rate was 49.2%. Overall incidence of post-operative hyperbilirubinemia was 55.4%. In patients with postoperative hyperbilirubinemia, the mean peak value for serum to-tal bilirubin was 104.8 (68.5-156.7) μmol/l. The hospital mortality in the hyperbilirubinemia group was significantly higher than that in the non-hyperbilirubinemia group(66.7% vs. 27.6%, P <0.01). Moreover, postoperative hypethilirubinemia (adds ratio = 3. 895, 95% confidence interval, 1.088 - 13.947 ; P = 0.037) and SOFA score (odds ratio = 1.214, 95% confidence interval, 0.987 - 1.494, P = 0.047) and APACHE Ⅲ score (odds ratio = 1.096, 95% confidence interval, 1.028 - 1.169 ; P = 0.004) were associated with hospital mortality after adjusting for preoperative levels of the total bilirubin, direct bilirubin, gender and age. Conclusion Postoperative hyperbilirubinemia is one of the complications in adult patients who undergo cardiotomy with ECMO support, and is associated with increased hospital mortality.

Objective To research the fibrosis characteristics of Atrial Fibrillation(AF) patients under microscope and its effect to post-operative sinus conversion of Radiofrequency ablation treatment.Methods Based on Lefi Atrial Dimension (LAD).Left atrial appendage tissue samples of 60 AF patients who received bipolar radiofrequency ablation treatment during open heart surgery between July and December 2011,were divided into 4 groups:group a (LAD≤50 mm),group b (50 mm ＜ LAD≤60 mm),group c (60 mm＜ LAD ≤70 mm),group d (LAD ＞ 70 mm),15 patients in each group.The levels of atrial muscle fibrosis and cell size differences are compared for colored slides of samples.Research are done for the difference of sinus rhythm restoration rate among the 4 groups based on ECG records at immediate,leaving hospital,and 3,6,12 months postoperative are collected for all groups.Results Differences of CVF and atrial muscle cell size measured under microscope are statistically meaningful(P ＜ 0.001).Sinus rhythm restoration rate differences at 6 month(P =0.039) and 12 month (P =0.037) post-operative are statistically meaningful.Further,immediate,leaving hospital,and 3,6,12 months postoperative sinus rhythm restoration rates are 93.3％,93.3％,93.3％,100％,100％ for group a,80.0％,73.3％,80.0％,80.0％,80.0％ for group b,66.7％,66.7％,66.7％,73.3％,66.7％ for goup c,and 53.3％,53.3％,53.3％,60.0％,60.0％ for group d respectively.Conclusion For rheumatic heart valve diseases patients who at 6 and 12 month post-operative,the greater the LAD,the higher the atrial fibrosis level,the greater the cell size,the lower the sinus rhythm restoration rate is.

BACKGROUND: Conventional hemodialysis mainly for cleaning uremic micro molecule substance, such as urea nitrogen or creatinine; however, few hemodialyses can clean uremic middle molecule substances (MMS). With prolonged dialysis duration, MMS accumulates in vivo and induces a series of complications. OBJECTIVE: To compare the efficiency of adsorptive dialysis (hemoperfusion unites hemodialysis) and conventional hemodialysis in cleaning uremic MMS. METHODS: Totally 60 maintenance hemodialysis patients were averagely divided into the adsorptive dialysis group and conventional hemodialysis group. First of all, hemoperfusion apparatus and dialyser were connected in series to take the adsorptive dialysis in the adsorptive dialysis group (hemoperfusion apparatus were equipped before dialyser). 120 minutes later, the hemoperfusion apparatus was toke off and continues to hemodialysis for 120 minutes. Duration of conventional hemodialysis was 240 minutes. Changes in clinical symptoms and levels of liver function, kidney function, serum electrolytes, hemocytes and uremic MMS were observed prior to and after treatment. RESULTS AND CONCLUSION: Adsorptive dialysis could remove the MMS notably. Compared with the conventional hemodialysis group, a single 120 minutes treatment could decrease MMS significantly (P < 0.05). The platelet levels were obviously decreased in the adsorptive dialysis group after treatment (P < 0.05), which were significantly different from the conventional hemodialysis group (P < 0.05). There was no significant difference in liver function, kidney function or serum electrolytes concentration. But related symptoms, such as the skin itch, sleep disorders and myalgia, were relieved more or less.

Objective To assess the quantitative relationship between the distribution of Himalayan marmot and its ecological environment,the terrain,the temperature and the precipitation,using remote sensing and geographic information system in Qinghai province.Methods The distribution of Himalayan marmot was located by Google Earth and ArcGIS software and by using field survey data provided by Chinese Center for Disease Control and Prevention.The corresponding ecological environment of marmot including terrain,temperature and precipitation were derived from the spatial information datasets.All results were processed according to the overlay and statistics analysis using ArcGIS software.Results Seventy-seven point twenty-seven percent(153/198) of Himalayan marmot were distributed in the area of elevation between 3000 and 4000 meters.The number of marmot reached the highest when the slope was between 0 and 17 degrees,and aspect range was between 91 and 270 degrees,180 degree was as south direction.During the period with the maximum temperature of the warmest month of 14.3-17.5 ℃,17.6-20.8 ℃ and 20.9-24.0 ℃,the distribution of marmot reached 95％(186/198) of the total area.Meanwhile,most of the marmot were presented in the area with average precipitation of 46-108 mm.Conclusions A quantitative analysis of appropriate ecological environment of Himalayan marmot in a large scope is carried uul successfully using remote sensing and geographic information system.The study indicates that spatial information technology has important applications in plague prevention and control.

Hepatic encephalopathy is a common metabolic neuropsychiatric syndrome in the development of end-stage liver disease. Since the concept of intestinal-liver-brain axis was proposed, the relationship between the pathogenesis of hepatic encephalopathy and the gut microbiota has been a hot research topic. In recent years, studies have confirmed that gut microbiota is involved in and affects various pathological processes of hepatic encephalopathy. This article combines the latest research progress at home and abroad to elaborate on the research status of regulating gut microbiota and thus interfering with the pathological process of hepatic encephalopathy, hoping to provide new ideas and methods for the intervention of hepatic encephalopathy based on the regulation of gut microbiota.

OBJECTIVETo investigate the long-term results of cricohyoidoepiglottopexy(CHEP) in the treatment of glottic carcinoma.

METHODSA retrospective chart review of 92 consecutive patients who underwent CHEP in the selected institut from January 1990 to December 2008. Of the 92 cases, 41 cases of stage I, 39 cases of stage II, 12 cases of stage III. The time for the decannulation and the removal of the nasal feeding and quality of phonation were used for evaluating postoperative functional rehabilitation. The estimated long-term survival rates were calculated by Kaplan-Meier method.

RESULTSAmong 92 patients, 26 cases (27 sides) received neck dissection and lymph nodes were pathologically positive in 3 patients (11.1%). All final surgical margins were negative for tumor invasion. Seven patients had postoperative radiotherapy and one had chemoradiation. Thirteen patients (14.1%) were found local recurrence and nine patients (9.8%) had postoperative metastases. Overall 3-, 5- and 10-year survival rates were 90.0%, 84.5% and 67.0% respectively. Cox multivariate analysis showed that the recurrence had significant influences on the overall survival rate.

CONCLUSIONCHEP not only is relatively easy to master, but also effective in the treatment of glottic carcinoma.
