Aim To observe the protective effects and explore the possible mechanism of lycopene on hepatic injury induced by the combining use of isoniazid(INH) and rifampicin(RFP) in rats.Methods Chronic hepatic injury model was induced by INH and RFP.Low dosage,middle dosage and high dosage of lycopene(10,20,30 mg?kg-1 body weight) were given to protect liver injury.The serum level of AST and ALT,liver index,contents of malondialdehyde(MDA),glutathion(GSH) and superoxide dismutase(SOD) in liver were measured.Hepatic pathological changes were also observed after giving lycopene.Results Lycopene could reduce the liver index,the serum level of AST and ALT and the content of MDA,raise the liver GSH content and promote the activities of SOD in liver tissue in rats.Degeneration and necrosis of liver tissues were relieved.Conclusion Lycopene has protective effects on the hepatotoxicity in rats induced by the combination of INH and RFP for a long time,and the mechanisms is related to of antioxidation action of lycopene possibly.

Objective: To study the technological parameters of the enrichment purification process of Baohe Pills with macroporous resin. Methods: With the enriched degree of hesperidin of Pericarpium Citri Reticulatae of Baohe Pills as a marker, the optimum technological parameters of the enrichment process were studied. Results: The optimum process is that 5mL of the extract of BaoHe Pills (500mg/mL) was adsorbed for 30min with a column of macroporous resin (R15mm?H100mm) and the resin was washed with 100mL of distilled water, then the hesperidin was eluted from the macroporous resin with 100mL of 50% ethanol. Conclusion: The elutive rate of hesperidin was above 95% by means of the macroporous resin. So this process enriching the active components of Baohe Pills is feasible.

Objective To explore the long-term effect, prognosis and administration of corticosteroid treatment on autoimmune pancreatitis (AIP). Methods Clinical data were analyzed in 13 diagnosed and followed up AIP patients of Peking Union Medicine College Hospital during August 2004 to August 2008. Results Of 13 patients, 12 were males and 1 was female, with a mean age of 58.7 years old, and a mean follow-up of 30 months. Of 11 patients compliated with bile duct disease,biliary stents were placed in 9 patients and already taken out. Corticosteroid treatment was received by cured patients. The average corticosteroid therapeutic time was 9.2 months, 7.9 months in 6 biliary stent placed patients, 13.4 months in corticosteroid treated alone patients, the statistical difference was significant (P = 0. 023). Serum inflammatory parameters normalized range from 5. 3 to 8.8 weeks. After corticosteroid treatment, pancreas enlargement improved in all patients at the first imaging reexamination (1.0 to 11.3 weeks), pancreatic size normalized in 9 patients with an average of 16.6 weeks corticosteroid treatment. No relapsing sign was found with imaging examination during follow-up. Of 8 newly onset diabetes patients, glucose level normalized in 4 patients after corticosteroid treatment. Two patients complicated with autoimmune hepatitis developed early hepatic cirrhosis symptoms at the end of the follow-up. Swollen submandibular gland enlargement relapsed in one patient after corticosteroid withdrawn for six months. Conclsion AIP patients responsed well to corticosteroid treatment. Placement of biliary stent could shorten corticosteroid therapeutic time.Patients with bile duct complications and newly onset diabetes could partially relieve after the corticosteroid treatment, the prognosis of patients with autoimmune hepatitis complications was relatively poor.

Objective To compare the efficacy and safety between Chinese generic imatinib (Xinwei(R),Jiansu Hansoh Pharmaceutical Group Co.,Ltd.) versus branded imatinib (Glivec(R),Novartis) in patients with newly-diagnosed chronic myeloid leukemia in chronic phase (CML-CP).Methods Patients with newly diagnosed CML-CP were enrolled and assigned to receive either Xinwei or Glivec at an initial dose of 400 mg/d according to patients' financial capability.The efficacy and adverse effects were evaluated.Results From January 2014 to September 2015,145 eligible patients were assigned to Xinwei (n =89) or Glivec (n =56) group.All patients were treated and followed up at least 3 months.At 3 months,the complete response rates were 95.5％ (85/89) and 100％ (56/56),major cytogenetic response rates were 74.2％ (66/89) and 80.4％ (45/56),and the proportions of achieving BCR-ALBIS ≤ 10％ were 76.1％ (67/88) and 82.1％ (46/56) in Xinwei and Glivec groups respectively (all P ＞0.05).With a median follow-up of 12 months,2 patients in each group progressed to accelerate or blast phase.Hematologic and non-hematologic side effects were similar between the 2 groups.Conclusions Early hematological,cytogenetic and molecular responses between Xinwei and Glivec are comparable in newly-diagnosed CML-CP patients.The progression rate and side effects are also similar between the 2 groups.

AIM: The expression of the Fas Antigen and induction of apoptosis by anti-Fas antibody in esoinophils in vitro were investigated. METHODS: Purified eosinophils from health donors were cultured for 72 h in the presence of human IL-5 and with or without anti-Fas monclonal antibody (MoAb) at various concentrations (1-1000 ?g/L). The expression of the Fas antigen on eosinophils was determined by immunocytochemistry. The changes of eosinophils viability and apoptosis were also studied. RESULTS: The Fas antigen was expressed on freshly isolated eosinophils, which had no significant changes after culture in the presence or absence of IL-5. The anti-Fas MoAb at different concentration suppressed significantly the IL-5-mediated eosinophils survival (78%?9%). When eosinophils were cultured in the presence of IL-5 (1?10 4 U/L) with anti-Fas MoAb (1 000 ?g/L), the percentage of alive cell decreased to 30%?12%( P

Objective To explore the effect of sodium butyrate(NaB) on phosphorylation/ acetylation of histone H3(ph/acH3) at G?-globin gene and A?-globin gene promoter regions in K562 cells.Methods K562 cells were devided into 2 groups:K562 cells were grown in the presence or absence of 0.5 mmol?L-1NaB for 48 h [K562(NaB) group] and untreated K562 cells group(K562 group).Semi-quantitative RT-PCR was employed to measure the levels of G?-globin mRNA and A?-globin mRNA.The real time PCR-based chromatin immunoprecipitation(ChIP) was used to detect the levels of ph/acH3 at G?-globin gene and A?-globin gene promoter regions.Results Compared with the K562 group,there was a 1.4-fold(t=-149.022,P=0.000) and 1.2-fold(t=-13.363,P=0.000) increase in G?-globin mRNA and A?-globin mRNA,respectively,in K562(NaB) group.The level of ph/acH3 at G?-globin gene and A?-globin gene promoter region increased by 2.9-fold(t=-12.833,P=0.006) and 3.2-fold(t=-10.484,P=0.000),respectively,in K562(NaB) group,compared with the K562 group.The %Input value of G?-globin and A?-globin promoter fragment was 10.0-fold(P=0.000) and 9.5-fold(P=0.000) higher than that value of Necdin gene promoter fragment in the K562(NaB) group,while the %Input value of G?-globin and A?-globin promoter fragment was 3.2-fold(P=0.000) and 2.7-fold(P=0.000) higher than that value of necdin gene promoter fragment in K562 group.Conclusions NaB improves the phosphorylation and acetylation of H3 at ?-globin gene promoter regions,and this may be one of the mechanisms of expression of ?-globin genes induced by NaB.

Objective The type 1 autoimmune pancreatitis is gradually being recognized, but the type 2 AIP is still very rare in Asia.This paper summarizes the clinical characters of type-2 AIP patients in Peking Union Medical College Hospital.Methods From January 2001 to December 2016,all type 2 AIP hospitalized patients who met the ICDC were included in the study.The clinical data, laboratory results and imaging features of all patients were recorded, verified and follow-up.Results Six patients with type 2 AIP were included in the study.The ratio of men and women was 2/1, with an average age of 38.4 years.67.7% (4/6) patients have UC.37.7% (2/6) of patients were asymptomatic.Three patients were diagnosed by pathology.50% (3/6) of patients showed mass of pancreas, and 50% (3/6) of patients showed pancreatic enlargement.Conclusions The clinical manifestations of the type 2 AIP patients in Peking Union Medical College Hospital are the same as those in foreign countries.

Objective To evaluate the effects of infective necrosis (IN) on prognosis in moderately severe or severe acute pancreatitis (AP).Methods According to the revision of Atlanta classification,from January 2001 to January 2015,admitted patients with moderately severe or severe AP were retrospectively analyzed.According to whether with the presence of persistent organ failure (POF) and / or IN,the patients were divided into four groups:group one with weither IN nor POF,group two with IN but without POF,group three with POF but without IN,group four with both IN and POF.The differences in disease severity and prognosis among groups were compared.Logistic regression and Cox proportional hazard regression model were used to analyze the effect of IN on prognosis.Results A total of 375 moderately severe or severe AP patients were enrolled.There were 211,43,90 and 31 patients in group one,two,three and four,respectively.A total of 121 (32.3％) patients with POF,74 (19.7％) patients with IN,and death in 63 (16.8％) patients.The mortality rate in patients with IN was 32.4％ (24/74),and which was 13.0％(39/301) in patients without IN.The mortality rates of group one,two,three and four were 1.9％(4/211),11.6％(5/43),38.9％(35/90) and 61.3％(19/31),respectively;mortality rate was in a trend of increasing,and the difference was statistically significant (x2 =109.672,P＜0.01).Both IN (OR=8.24,95％CI2.09 to 32.46) andPOF (OR=8.31,95％ CI2.48 to 27.87)were independent risk factors of mortality of AP patients (both P＜0.01).Both IN (OR=2.04,95 ％CI 1.19 to 3.48,0.002) and POF (OR=5.25,95％CI 2.36 to 11.65) also were independent risk factors of shortened survival time of AP patients (both P＜0.01).Conclusions IN is an independent risk factor of disease severity and poor prognosis in AP.The prognosis is the worst in AP patients with both POF and IN.

Objective To evaluate subclavicular angiography with brachial-axillary artery externally and temporally occluded in depicting hemoptysis-related ectopic arteries originating from shoulder, neck and chest wall in the interventional treatment of hemoptysis. Methods A retrospective analysis of the medical records and angiograms of 103 patients who underwent transarterial procedures for hemoptysis was carried out. The arteries originating from the subclavicular arteries supplying the shoulder, the neck and the chest wall, ectopic bronchial arteries (EBA) as well as non bronchial systemic arteries (NBSA), were depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. The number and distribution of the responsible aberrant arteries were investigated. Results Of the hemoptysis-related arteries(n=372) depicted and embolized in the studies, 51.9% was normally-originated bronchial arteries(n=193),6.7% was ectopic bronchial arteries (n=25),41.4% was NBSA(n=154).Both anomalous and NBSA arising from subclavicular-axillary area(n=80) were accounted for 21.5% (80/372) of all aberrant arteries, and 44.7%(80/179) of all anomalous and NBSA (n=25+154=179).Of those arising from subclavicular-axillary arteries,56.3%(45/80) were found to be originated from the internal thoracic artery (n=45),98.2%(112/114)of responsible internal thoracic arteries and their distal branches were well depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. Conclusion Subclavicular-axillary artery is a very important vessel where EBA and NBSA originate. Subclavicular angiography with brachial-axillary artery externally and temporally occluded could help to determine the abnormal arteries in the region quickly. The method should be taken as a routine procedure for interventional treatment of hemoptysis.
