Frequently,there is a lack of safety data about diagnostic method and drug therapy of digestive diseases during pregnancy. It is profitable to understand the limited evidences of safety data about diagnosis and drug therapy of digestive diseases during pregnancy,which will allow the accurate evaluation and risk assessment on diagnostic method and treatment during pregnancy. High-quality clinical study on patients with pregnancy is helpful for the management of common digestive diseases among this special population.

The American College of Gastroenterology( ACG)released the first clinical guideline for drug-induced liver injury( DILI)in June,2014:the diagnosis and management of idiosyncratic drug-induced liver injury( IDILI), which includes all aspects of IDILI,such as risk factors,diagnosis,differential diagnosis and treatment. The guideline discusses especially the issues on herbal and dietary supplements( HDS)induced liver injury and DILI in patients with chronic liver disease. The guideline is of great value for standardizing the clinical diagnosis and treatment,providing the best recommendations for management of the patients with DILI. Since the evidence of research in the field of DILI is relatively weak at this moment,the clinicians should consider the possible individual difference of the patients under the frame of guideline for making the best clinical decision.

Objective To study the effects of lung recruitment maneuvers (RM)with different duration combined with low tidal volume (TV)ventilation in acute respiratory distress syndrome (ARDS) with pulmonary and extra-pulmonary origin(ARDSp / ARDSexp). Methods Twenty-six ARDS patients with ventilation were selected including 10 patients of ARDSp (ARDSp group) and 16 patients of ARDSexp(ARDSexp group). All patients were given intermittent high-positive end expiratory pressure (PEEP) combined with low tidal volume RM in the base of usual ventilation. Effects of different duration of RM were evaluated and compared in the patients of ARDSp / ARDSexp. Results MAP decreased and HR increased when sustaining time of RM was above 60 seconds. Significant differences were showed compared with that before treatment. MAP and HR returned to normal after RM stopped.Compared with the state before RM,Pplat and Crs increased immediately after RM (P<0.05). When RM lasted above 60 seconds, Pplat increased significantly compared with that when RM continue lasted 40-59 seconds.But Crs,OI and SpO2 didn't increase obviously. Treatment effects of RM in patients of group ARDSexp were more obviously than those in patients of ARDSp group. There were 1 case of pneumothorax and 3 cases of pneumoderma in ARDSp group and 2 cases of pneumoderma in ARDSexp group when RM lasted above 60 seconds. Conclusions RM with intermittent high-PEEP on low TV is effective to ARDS and best duration is 40～59 seconds. The patients of ARDSexp, with pulmonary interstitial edema as the main pathology, respond better to RM than patients in ARDSp with pulmonary consolidation.

Objective To investigate the risk factors of syncope symptom in patients with pulmonary embolism (PE).Methods 457 patients with confirmed pulmonary embolism were recruited in the study.They were divided into two groups:the syncope group (44 patients) and the group without syncope (413 patients).The clinical manifestation,laboratory examination,physical examination,imagingof all patients were analyzed by unconditional logistic regression.Results (1) Single factor analysis,prevalence of syncope was 9.6％ (44/457) in these patients with PE.Those with syncope had some higher risk factors,including age over 60,coronary heart disease,hypertension,stroke and lower limb vein thrombosis history.The proportion of falling pressure chest painand centricity thrombus in syncope group were increasing compared with the groupwithout syncope.Pulmonary embolism severity index (sPESI) score was higher than groupwithout syncope.(2) Multivariate analysis showed that hypertension coronary heart disease and Centricity thrombus were the independent correlates of the presence of syncope in the patients with PE.Conclusions Patients who had histories of hypertension and coronary heart disease may have the higher risk factors of syncope.Blood pressure falling and central localization may be more likely to happen in PE patients with syncope.

Objective To explore the level of the oxidative stress and the DNA oxidative damage of peripheral blood mononuclear cells (PBMCs) in pulmonary embolism (PE) patients after remission and in acute exacerbation.Methods The PBMCs DNA damage in 35 PE patients (test group) after remission and in acute exacerbation respectively and in 33 healthy persons (control group) was detected by single-cell gel electrophoresissingle (Comet assay).The total antioxidative capacity (TAC) in blood plasma was measured by phenanthroline colorimetric analysis.The contents of malondialdehyde (MDA) in blood plasma was measured by thiobarbituricacid colorimetric analysis.The capacity of glutathion peroxidase (GSH-PX) in blood plasma was measured by the method of improved Hafeman direct determination method (DNTB).Results The level of TAC,GSH-PX in test group after remission were significantly higher than those in acute exacerbation[(6.86 ± 1.21) kU/L vs.(5.18 ± 1.13) kU/L,(165.25 ± 41.96) kU/L vs.(137.23 ± 38.52) kU/L] (P ＜0.01),and they were all significantly lower than those in control group [(7.85 ± 1.44),(189.92 ± 51.32) kU/L] (P ＜ 0.01).The level of MDA in test group after remission was significantly lower than that in acute exacerbation [(5.58 ± 1.89) μmol/L vs.(7.26 ± 2.25) μmol/L] (P ＜ 0.01),and they were significantly higher than that in control group [(3.71 ± 1.52) μmol/L] (P ＜ 0.01).The arbitrary units (AU) of PBMCs DNA damage in PE patients after remission (29.01 ± 6.75) was significantly lower than that in acute exacerbation (42.13 ± 8.01),and they were all significantly higher than that in control group (15.12 ± 4.36),there were significant differences (P＜ 0.01).There were negative correlations between the PBMCs DNA damage and the level of TAC in PE patients after remission and in acute exacerbation (r =-0.695,P ＜ 0.01 ;r =-0.536,P ＜ 0.01).There were positive correlations between the PBMCs DNA damage and the contents of MDA in PE patients after remission and in acute exacerbation (r =0.513,P ＜ 0.01 ;r =0.628,P ＜ 0.01).There were negative correlations between the level of TAC and the contents of MDA in PE after remission and in acute exacerbation respectively (r =-0.534,P ＜ 0.01 ;r =-0.486,P ＜ 0.05).There were positive correlation between the level of TAC and GSH-PX in PE patients after remission and in acute exacerbation (r =0.512,P ＜ 0.01 ;r =0.497,P ＜ 0.01).Conclusions There are oxidation/antioxidation imbalance,oxidative stress and the PBMCs DNA damage in PE patients.There is positive correlation between the PBMCs DNA damage and the oxidative stress.After remission,the level of the oxidative stress and the PBMCs DNA oxidative damage in the same PE patients is improved respectively.

Objective To assess the renal safety of adefovir dipivoxil (ADV) in Chinese patients with chronic hepatitis B (CHB).Methods A retrospective study was performed on 1 013 CHB patients from Chinese ADV multicenter clinical trials (ADF30001 and ADF106632).All patients were administrated with ADV 10 mg daily.The serum creatinine and phosphorus levels were measured in different time pointsduring 104-week treatment.Nephrotoxicity was defined as an increase ≥44.2 μ mol/L from baseline in serum creatinine or a serum phosphorus value of ＜ 0.4845 mmol/L on two consecutive occasions.Paired t test was used to analyze serum creatinine and phosphorous data before treatment and at different time points during treatment.Results At week 28,week 52,week 80 and week 104,the median levels of serum creatinine were 74.963,76.996,76.820 and 77.969 μmol/L,respectively,and there were no significant differences from baseline (t =0.91,0.23,0.59 and 0.97,P ＞ 0.05).No patient experienced a ≥ 44.2 μmol/L increase from baseline.For serum phosphorus,the median levels at week 28,week 80 and week 104 were 1.098,1.088 and 1.048 mmol/L,and there were significant decreases from baseline (t =2.34,3.06 and 4.94,P ＜0.05 or ＜ 0.01).The cumulative incidence of serum phosphorus abnormality was 0.8％ (8/104).There were no confirmed serum phosphorous decreases to ＜ 0.4845 mmol/L.Conclusion Two years treatment with ADV (10 mg/d) does not result in marked nephrotoxicity,indicating that ADV 10 mg daily is well tolerated by Chinese patients.

Objective To investigate the indications and efficacy of endovascular stenting for the treatment of thoracic aortic aneurysm.Methods From March 2005 to October 2008,21 patients with Stanford type B aortic dissection,5 cases of pseudoaneurysm,and 2 patient with intramural hematoma complicated with ulcer of the aortic wall were treated by endovascular stenting under general(2 cases) or local(26 cases) anesthesia in our hospital.Medtronic Talent stent was employed in 10 cases,Medtronic Valiant stent was used in 12,and microinvasive straight-type stent was used in 6 patients.Results The operation was completed successfully in all of the 28 cases.Angiography showed that the gaps in the aorta were closed without endoleak.No patient had chest pain or neurological complications.The patients were discharged in(4.5?1.1) days(range 3-7 days).Five patients developed fever after the operation and were cured by indomethacin in one month.One week after the surgery,in 21 cases,CT scan showed enlarged aortic dissection,improved blood supply,thrombus in the false lumen of the thoracic aorta,and a false lumen in the abdominal aorta.In the 5 cases with pseudoaneurysm,CT scan confirmed that the rupture was closed with thrombus being detected in the lumen.The aortic ulcers that were detected in the 2 cases,who had intramural hematoma,were covered by the stents.Of the patients,a follow-up of(21.3?10.2) months(range 1-40 months) was available in 23 patients,who had no complications during the period.Conclusions Endovascular stenting is a simple,safe and effective method for Stanford type B aortic dissection,pseudoaneurysm,and intramural hematoma,resulting in quick recovery,less complications,and short hospital stay.

Objective: To study the biodegradable of coral PLA composite artifical bone combined with bBMP or rhBMP as a new kind of bone substitute material. Methods: The composites were implanted into the muscle pouches of mice after combined with rhBMP-2 or bBMP respectively. Ectopic osteoinductive activity of rhBMP-2 or bBMP was examined and compared by histology and histo-morphometry.Results: rhBMP-2 and bBMP had different osteoinductivety. rhBMP-2 appeared to induce less bone and more angioid tissue and marrow. While bBMP seemed to have opposite effects. Conclusion: bBMP is more osteoinductive than rhBMP-2.

Background and purpose:Measurement of tumor markers in serum is widely used for the diagnosis of lung cancer, but the positive rates of single marker for diagnosis of lung cancer were not high. This study was to investigate the clinical value of combined measurement of serum CYFRA21-1,NSE,CEA,CA19-9,CA125 for the diagnosis of lung cancer. Methods:The levels of CYFRA21-1,NSE,CEA,CA19-9,CA125,SCC were assayed and compared between the lung cancer group(135 cases) and cancer-free control group(20 case) by electrochemiluminesence immunoassay.Results:The levels of CYFRA21-1,NSE,CEA,CA19-9,CA125 and SCC in the lung cancer group were (7?8) ng/ml,(30?29) ng/ml,(65?293) ng/ml,(110?379) U/ml,(122?412) U/ml and (2?7) ng/ml, respectively, which were higher than those in the control group. The levels of the six tumor markers were associated with pathology of lung cancer, the levels of CEA were (11?25)?10 ng/ml,(2?4) ?10 ng/ml,(2?3)?10 ng/ml in the adenocarcinoma , squamous cell carcinoma and small cell carcinoma cases respectively; the levels of CA125 were (21?48)?10 U/ml,(48?57) ?10 U/ml,(5?4)?10 U/ml in the adenocarcinoma ,squamous cell carcinoma and small cell carcinoma patients, respectively; the levels of CA199 were (17?44) ?10 U/ml,(5?12)?10 U/ml,(4?4) ?10 U/ml in the adenocarcinoma, squamous cell carcinoma and small cell carcinoma patients, respectively. The levels of CEA,CA125,CA19-9 in the adenocarcinoma were higher than those in the squamous cell carcinoma and small cell carcinoma, but there was no significance different(P
