The hospital stay in drainage group[ average 71(43-101)days] was significantly longer than that in non- drainage group [ average 47(29-81)days](P=0.05). Conclusions If a sufficient preoperative preparation is performed,one stage PD operation is a benificial method for peri-ampullar carcinoma patients complicated with severe obstructive jaundice.

Objective To study whether the warm ischemia-reperfusion injury can be alleviated if the hepatic glycogen content were increased before liver transplantation.Methods The male SD rats as donors and recipients were divided into groups A,B and C randomly.In group A,the rats were al- lowed access to solid and water ad libitum;In group B,the rats drank glucose liquor for 4 days prior to liver harvesting;In group C,the rats were intravenously injected with 50% glucose besides the protocol in group B 3-4 h prior to liver harvesting.According to the non-heart-beating time(the non- heart-beating time were set into 60,90,120 and 150 min),the rats in groups A,B and C were divided into 4 subgroups,and the orthotopic liver transplantation was performed and the hepatic glycogen and ATP contents were measured.The one-week survival rate and the serum levels of MDA and SOD in the recipients were determined after liver transplantation.Results The hepatic glycogen and ATP con- tents in groups B and C were more than those in group A significantly(P

Objective To investigate clinical feature,diagnosis and prognosis of eosinophilic gastroenteritis(EG),and to analyze the causes of misdiagnosis.Methods Eleven children diagnosed as EG were studied.Their history,clinical manifestations,laboratory tests and endoscopies and treatment,follow-up data were analyzed.The data were analyzed by SPSS 10.0 software.Results 1.The children with EG usually had abdominal pain(5 cases),diarrhea(7 cases),hemafecia(5 cases) and sometimes with fever(2 cases).2.EG and allergy in children was closely related with disease(54.55%).3.Peripheral blood eosinophil(EOS) count increased significantly,and declined when symptoms eased(18.18%).4.Endoscopic manifestations were not specific,the mucosa could see sheet erosion,shallow ulcers,congestive spots or bleeding spots,mainly in antrum,duodenum,terminal ileum,ileocecal junction.The biopsy showed that a large number of EOS infiltration.5.Imaging were not specific,CT or gastrointestinal barium meal examination did not show special often(90.91%).When muscular wall was affected(9.09%),imaging presentations of EG could be partly obstructive.6.Glucocorticoid therapy could relieve symptoms and EOS.Symptoms probably recured by good prognosis.7.EG was a self-limiting allergic diseases,although the attack may be repeated.After long-term follow-up,most had good prognosis and without malignant.Conclusions Clinical and endoscopic presentations of EG are not specific,therefore the presence of EOS in gastrointestinal mucosa strongly indicate the diagnosis.It was easy to misdiagnosis.Biopsy pathology and cli-nical characteristics are the key to diagnosis.

Objective To evaluate the clinical presentation,pathologic features,diagnosis and treatment of hepatic angiomyohponm(HAML).Methods Retrospective analysis was made on 22 HAML cases in terms of clinical finding,images,pathologic examination and surgical treatment.Results Of the 22 patients,6 were male and 16 were female.The average age was 48.2 years.Seventeen patients had no clinical symptoms.None had the history of hepatitis virus infection.None of them was complicated with renal AML.None had tlle history of taking oral contraceptives in the sixteen female patients.Serum AFP、CEA、CA19-9、CA242 levels were all within normal limits.The correct diagnostic rate of BUS.CT and MRI was 2l%(4/19)、23.5%(4/17)and 25%(2/8),respectively.All tumorts were single nodule with a diameter of 4～17 cm,without complete capsula.All these 22 patients underwent tumor resection,including partial liver resection in 17 patients,left hemihepatectomy in 5.One patient died of postoperative complication,one patient suffered from temporary bile leak.The HMB45 positive rate by immunohistochemical method was 100%.Extramedullary hemopoiesis was found in 4 patients.Follow up of 6 months to 17 years in 91%(20/22)patients found no tumor recurrence. Conclusions HAML had no specifiC symptoms.The preoperative imaging diagnosis is difficult.Surgical resection is the therapy of choice for HAML.

Objective: To obtain the bFGF mimic peptide binding to FGFR via phage display, and to provide the base for developing peptide agonist of bFGF. Methods: Using Balb/c 3T3 cells as the target cells and COS-7 cells as the subtractive panning, the phage display heptapeptide library was biopanned for 4 rounds to obtain the single phage clones. The affinity and the specificity of the clones were assessed by ELISA. DNA sequencing was applied to further analyze the positive clones. Results: Twelve positive clones were selected from the enriched phages. A group of hydrophobic peptides containing a conserved motif, PR, was identified. Conclusion: Two bFGF mimic heptapeptides binding to FGFR were selected, which may be used as the candidates for bFGF agonist.

To study the cognitive effects of diterpene ginkgolides (DG), transient middle cerebral artery occlusion (tMCAO)-induced rats were established. tMCAO-rats induced by suture method were divided into sham operation group, solvent control group, NBP group, DG group. The animal experiments in the present study were performed in accordance with the Ethical Guidelines of the Laboratory Animal Welfare Ethical Committee of Peking Union Medical College (00000646, 00000635). The effects of DG on tMCAO rats were evaluated by neurological severity score, cerebral infarction volume measurement, step-down and Morris water maze test. In the acute tMCAO rat model, 100 mg·kg^-1 DG improved the neural score and infarction volume. In the chronic tMCAO rat model, DG 100 mg·kg^-1 significantly improved the survival rate of tMCAO-induced rats. The Morris water maze results showed 100 mg·kg^-1 DG decreased the latency of tMCAO-induced rats to find the platform, while the effect was weaker than the NBP. However, DG 30 mg·kg^-1 did not show a significant effect. In conclusion, DG exerted a therapeutic effect on transient middle cerebral artery occlusion.

Objective To investigate the clinical efficacy and safety of adefovir dipivoxil (ADV) in combination with bicyclol for the treatment of chronic hepatitis B ( CHB ) in seniors.Methods 96 senior patients with CHB were randomly divided into two groups,the treatment group and the control group.On the basis of routine liver protective treatment,patients in the treatment group received ADV (10 mg/d ) and bicyclol tablets( 25mg,tid.)orally,and those in the control group were orally administrated ADV tablets (10 mg/d) only.The treatment course for both groups was 24 weeks. Serum ALT,AST,and alterations of virological parameters were observed before and after the treatment.Results Before and at the end of the 24 weeks treatment,ALT level for the treatment group was (208.44 ± 94.22) and (34.47 ± 12.79) U/L,and those for the control group was ( 205.73 ± 96.48 ) and (44.20 ± 21.96 ) U/L,respectively ( difference between groups P ＜0.01 ).At the end of the 24 weeks treatment,ALT normalization rates for the treatment group and the control group were 76.6％ and 54.5％,respectively,and AST normalization rates for them were 76.6％ and 54.5％,respectively (both differences between groups P ＜ 0.05 ) ; HBV DNA loads for the treatment group and the control group were decreased by (3.1 ± 1.40) lgIU/ml and (2.98 ± 1.17) lgIU/ ml,respectively ( difference between groups P ＞ 0.05 ).The incidence rates of adverse events between two groups were not statistically significant.Conclusion It suggested that the treatment of ADV in combination with bicyclol for senior patients with CHB is effective and safe.

OBJECTIVETo establish a new method using AOTF-Near infrared spectroscopy (NIRS) for quick determination of tanshinone II(A) and salvianolic acid B in Fufang Danshen tablets.

METHODHPLC was used as a reference method to determine the contents of tanshinone II(A) and salvianolic acid B in Fu Fang Dan Shen tablets. Multivariate calibration models based on PLS1 algorithm were developed to correlate the spectra and the corresponding values determined by the reference methods.

RESULTRMSECV (root-mean-square error of cross-validation) of the models for tanshinone II(A) and salvianolic acid B were 0.0103 and 0.1868 respectively. The correlation coefficients of the calibration models were 0.9873 and 0.9832 respectively. External validation with external validation samples proved that the relative coefficient of the predicted value and the truth value were R2 = 0.9743 and R2 = 0.9886 respectively, with measured recycle rates of 103.0% and 99.0%.

CONCLUSIONNIRS can be used in the determination of tanshinone II(A) and salvianolic acid B, which sets up the foundation of product-line control of Fuang Danshen tablets.
