Objective To investigate the clinical value of earlier period C reactive protein, hematocrit level and combining these two factors in predicting the severity in patients with acute pancreatitis. Methods Hct ad CRP within 24h after admission were evaluated, and the differences between severe acute pancreatitis and mild acute pancreatitis were analyzed. The effectiveness in predicting the severity in AP patients was evaluated by ROC curve. Results The levels of Hct and CRP in SAP group were significantly higher than those in MAP group (P<0.05). The sensitivity of CRP and Hct were 66. 67% and 50%, the specificity were 85.51% and 81.16%, the positive predictive values were 54. 55% and 40.91%, and the negative predictive values were 90. 77% and 86. 15%, respectively. The sensitivity of combi-ning CRP and Hct was 66. 67%, the specificity was 85.51%, the positive predictive value was 40. 91%, and the negative predictive value was 90. 77%. Conclusion The earlier period C reactive protein and hematocrit level have prognostic value, and combination use of these two factors are more sensitive in evaluating the severity in patients with acute pancreatitis.

0.05).Conclusions Neither the new nor old SIRS diagnostic criteria had a high conforning rate with neonatal critical illnesses;There was no significant difference between them in each clinical item.It shows that the new SIRS diagnostic criteria is not superior to the old one,therefore we should improve the neonatal SIRS diagnostic criteria in the future.

Objective To investigate the ex pr ession of squamous cell carcinoma antigen (SCC-Ag) and carcinoembryanic antigen (CEA) and its clinical significance in patients with lung cancer. Meth ods The pre-treatment serum from 134 patients with lung cancer from 1998 to 2002 were analyzed for the SCC-Ag level and CEA level by IMX, and the correlation of the SCC-Ag level and CEA level with the clinicopathologic charac teristics were also detected. Results Significant correlations were found between the pre -treatment SCC-Ag level, and CEA level and the pathologic classification, clin ical stage, the positive rate of diagnosing lung cancer was raised by combined a ssay with serum SCC-Ag and CEA. Conclusion Pre-treatment and after-treatment measurement of serum SCC-Ag level and CEA level can be used for diagnosis, prediction of pr ognosis and monitor of after-treatment recurrence in patients with lung cancer.

Objective To investigate the value of emergent endoscopy in the acute nonvariceal gastrointestinal bleeding.Methods Retrospective analysis was done in patients with melena or haematemesis in the ward from Jan 1st 2003 to Dec 31st 2007.For emergent group,the patients took endoscopy in 48 h after bleeding.For selective group,the patients took endoscopy after 48 h.Medical outcomes and resource utilization were compared between two groups.Results The average age of 332 patients(246 males and 86 females)was(45.9?18.8)years old.In the median and low risk patients,the length and the cost of hospitalization,blood transfution and the use of PPI were lower in the emergent group than in the selective group.In the high risk patients,the above variables had no statistical difference.Conclusion For the patients whose Rockall Score were less than 5,emergent endoscopy could decrease the length and the costs of hospitalization,the transfusion volumes and the use of PPI.However,for the patients whose Rockall Score were more than 5,the advantage of emergent endoscopy need further discussion.

OBJECTIVETo evaluate the efficacy and safety of high doses of thymopentin (10 mg/d) combined with transartery chemoembolization for primary liver cancer.

METHODSFifty primary liver cancer patients were randomly divided into two groups: therapeutic and control group, and all were treated with transfemoral artery chemoembolization (TACE) with oxaliplatin 150 mg, pharmorubicin 50 mg, 5-Fu 750 mg, CF 300 mg and lipiodol 20 ml. Therapeutic group (25) were added 10 mg thymopentin daily after TACE: i.v. on dl - d5, and im on D6 - D21.

RESULTSThere was a significant difference in adverse effect and toxicity such as naupathia,fever, swirl, asthenia observed between two groups (P < 0.05). No difference in either pre- or post-chemotherapy peripheral blood examination and biochemical assay was found between two groups (P > 0.05). In control group, CD4+ cell was 37.92% +/- 8.71% in pre-treatment, which decreased to 29.16% +/- 8.21% in post-treatment with a significant difference (P < 0.01), whereas there was no evident difference in CD4+ cell between pre-treatment and post-treatment in the treatment group.

CONCLUSIONTransartery chemoembolization combined with high dose of thymopentin in the treatment for primary liver cancer is effective and safe, and can significantly improve the immune function and the chemotherapy tolerance.

The deep fermentation technique of Tricholoma matsutake is systemically studied in this paper firstly. The best culture determined by orthogonal test is 3g/L of cornflour, 1g/L of glucose, 1g/L of bean cake flour, 1mL/L of corn steep liquid, 1g/L of KH 2PO 4. The best fermenting condition is: 25℃, rotating speed 160 r/min, pH5.0,inoculating amount 10%, 120mL culture medium per 500mL flask. Under these conditions, the mycelia reach 12.94g/L after fermenting 12d.

Phytases are studied widely in plants and microorganisms. Interest in these enzymes has been stimulated by the fact that phytase has the advantage in forage, food process and medicine. This paper reviews recent trends on the production, purification, properties and gene of microbial phytases.

An organic solvent tolerant isolate A213 originating from soil samples were successfully isolated via direct plating method using 10g/L of toluene as the sole carbon source and transparent cycle plate assay method.It was identified as Yarrowia based on its characteris- tics.The results in shake flask cultivation showed that the suitable tipase producing media were(g/L):yeast extract 40,vegetable oil 10, MgSO_4?7H_2O1,KH_2PO_4 5.Under optimal culture conditions (27℃and pH 6.5 ),the maximal lipase activity could reach 67.8 IU/ mL The optimal pH and temperature for the hydrolysis of p-nitrophenyl acetate by crude lipase were pH6.5 and 40℃The enzyme was sta- ble under 70℃and pH 5.5～8.5.Then isolate A213 was found to produce the lipase which can synthesize L-ascorbyl palmitate in tert-amyl alcohol validated by the thin-layer chromatography.

Objective To retrospectively evaluate the mammographic features of breast ductal carcinoma in situ (DCIS)and DCIS with small invasive foci,and to analyze the correlation between the mammographic findings and the prognostic biologic factors.Methods The mammographic examination was performed in 95 consecutive women with breast DCIS(n = 50)and DCIS with invasive foci(n = 45 ).The prognostic biologic factors including progesterone receptor(PR),C-erbB-2,and p53 were evaluated in 62 of 95 cases.Categorical data were expressed as percentages and analyzed by using the X~2 test,and furthermore the odds ratio was measured.Results(1)Only one abnormality was seen on mammography in 62 patients. Combined two abnormalities on mammography were seen in 26 patients.Mammograms were normal in 7 patients.(2)Calcifications with or without other abnormality were noted in 62 cases.Of them,73% (n =45)had higher probability of malignancy calcifications and the others were intermediate concern calcifications.Clustered calcifications(36 lesions)was the most common distribution,which usually accompanied by another abnormality.And then were segmental(18 lesions)distributed pattern.As far as the shape of mass (n = 22)was concerned,the oval shaped lesion(13 cases)was the most common,and the margin of the mass appeared as ill-defined in 15 eases,microlobulated in 1,circumscribed in 4,and obscured in 2,respectively.Isodensity mass had a higher frequency in this group(12/22,55%).Other non-calcification findings included architecture distortion(7 cases),local asymmetry (15 cases),global asymmetry (5 cases),and solitary dilated duct (3 cases),and most of them accompanied with other signs. (3)For expression profile of the biological factors,significant differences were found among malignant calcification group,intermediate concern calcification group,and non-calcification group. The odds of PR positive for the lesions noted as non-calcification were 11.00 times higher (X~2 =8.571 ,P=0.003 ;95% CI, 1.998—60.572)than the lesions noted as intermediate concern calcifications,and 8.80 times higher (X~2 = 9.748,P=0.002 ;95% CI,2.024—38.253)than the lesions noted as malignant calcifications.The odds of C-erbB-2 positive for the lesions showed as malignant calcifications were 12.35 times higher (X~2=7.353, P=0.007 ;95% CI,1.447—105.443)than the lesions showed as non-calcification,and 5.74 times higher (X~2=4.977,P = 0.026;95% CI,1.110—29.645)than the lesions showed as intermediate concern calcifications.Conclusion The mammographic features of DCIS and DCIS with small invasive foci were characteristic.Mammographic findings could be a prognostic markers,which could provide a possibility for making a treatment plan.

Objective To evaluate the efficacy and safety of fully covered self-expandable metal stents (FCSEMS) implanted by endoscopic retrograde cholangiopancreatography (ERCP) for patients with benign biliary stricture (BBS).Methods The clinical data of 38 patients with BBS underwent ERCP and FCSEMS placement between January 2012 and January 2016 were retrospectively recorded.Success rate of BBS,adverse events related to ERCP and stricture recurrence were analyzed.Results A total of 38 patients underwent FCSEMS placement with a mean time of stent in dwelling for 8 months (range:3-13months).During follow-up after the stent was removed,death of 1 patient after liver transplantation was due to unrelated cause.The mean follow-up time was 13 months (range:2-52 months) for other patients.Stricture recurrence occurred in 6 patients,including 2 cases of gallstone-related biliary strictures,1 case of chronic pancreatitis-related biliary strictures,2 cases of liver transplantation-related biliary strictures,and 1 case of post surgical-related biliary strictures.Stricture resolution occurred in 31 cases with 83.8％ (31/37) success rate,including 90.0％ (18/20) gallstone-related biliary strictures,75.0％ (3/4) chronic pancreatitis-related biliary strictures,80.0％ (8/10) liver transplantation-related biliary strictures,and 66.7％ (2/3)post surgical-related biliary strictures.The incidence of post-ERCP complications was 21.1％ (8/38),including mild pancreatitis in 5 case,hyperamylasemia in 2 cases,cholangitis in 1 case.All patients were cured by conservative treatment.Conclusion FCSEMS are effective and safe for BBS.Further studies are needed to assess the indwelling time of FCSEMS,whether FCSEMS are superior to multiple plastic stents and the different efficacy of FCSEMS for BBS caused by different etiology.
