Objective To investigate the corelationship between proton pump inhibitors (PPI) and the incidence of hospital-acquired pneumonia (HAP) in abdominal surgical patients. Methods A total of 283 cases admitted from 2010 to 2014 were divided into PPI group (n = 326) and HRA group (n = 92). In PPI group, patients were divided into omeprazole subgroup (subgroup A, n = 146), lansoprazole subgroup (subgroup B, n = 102) and pantoprazole subgroup (subgroup C, n = 78) by the types of PPI. In HRA group, patients were divided into famotidine subgroup (subgroup D, n = 58) and ranitidine subgroup (subgroup E, n=34) by the types of histamine-2 receptor antagonist (H2RA). The incidence of stress ulcer bleeding (SUB) and HAP were calculated, while mechanical ventilation period (MV), ICU stay and 28-day-mortality were compared. Results There were lower incidences of SUB and HAP, shorter MV and ICU stay and lower 28-day-mortality in PPI group than those in HRA group (P < 0.05). In three subgroups of PPI group, there were no significant difference on incidence rate of SUB and HAP, as well as MV, ICU stay and 28-day-mortality. Conclusion The incidence rates of SUB and HAP are lower by using PPI than H2RA in abdominal surgical patients, as well as MV, ICU stay and 28-day-mortality. Different types of PPI have no effect on the incidence rate of HAP in abdominal surgical patients.

Objective: To analyze the diagnostic methods and risk factors of female lung cancer, and to investigate the role of flberoptic bronchoscopy in the early diagnosis of lung cancer. Methods: The bronchoscopy data of 238 female lung cancer patients seen in our hospital between January 2005 and December 2008 were enrolled. The fiberoptic bronchoscop-ic features with clinical imaging, main risk factors of lung cancer and the pathological types were analyzed. χ~2 test was used for statistical analysis. Results: The major pathological type of lung cancer was adenocarcinoma in females younger than 40 years and squamous cell carcinoma in patients older than 60 years. The proliferative type was correlated with squa-mous cell carcinoma. Its imaging manifestion was a mass and the main risk factor was smoking. The infiltrating type was correlated with adenocarcinoma. Its imaging manifestation was mainly pleural effusion and the main risk factor was indoor soot inhalation. Conclusion: Females exposed to indoor soot inhalation for a long time especially those with a number of risk factors should be offered a screening with low dose CT (LDCT) regularly. Fiberoptic bronchoscopy and cytohistology are of great value for early diagnosis of lung cancer in those with abnormal findings in CT.

Objective To know phthalates(PAEs) pollution in drinking water of Nantong City. Methods With solid phase extraction and gas chromatography-mass spectroscope(GC-MS),main phthalates in drinking water were determined. Results Phthalates could be detected in all the source water, product water and tap water samples, mainly were di-n-butyl phthalate(DBP) and di(2-ethylhexyl) phthalate(DEHP),ranged from 1.25 to 4.59 ?g/L and from 0.97 to 3.57 ?g/L respectively. PAEs levels in product water were less than those in source water. The highest removal rate of DBP was 50%. PAEs levels in tap water were higher than those in product water,sometimes even higher than those in source water. Conclusion PAEs can not be effectively removed from source water after general water treatment process.

Objective To investigate the relation between positive fluid balance and the prognosis in severe sepsis patients with acute kidney injury (AKI).Methods A retrospective analysis of clinical data of 90 patients in our department was carried out.According to the final outcome,patients were divided into survival group (n =26) and non-survival group (n =64),in which the relation between patients' positive fluid balance and the prognosis was evaluated.Results (1) There was no statistically significant difference in the age and severity between survival group and non-survival group of patients with severe sepsis and consequent AKI,but the patients in non-survival group had greater volume overload.Compared with the survival group,higher mean fluid balance [(1 112.12±546.85) mLvs.(644.69±474.93) mL,P=0.00],and less urine output [(1 224.07 ± 708.79) mL vs.(2 032.36 ± 723.53) mL,P =0.00) in non-survival group.(2) There was no significant difference in mortality between early and late continuous renal replacement therapy (CRRT) during ICU care.However,the average daily fluid load in late CRRT patients was significantly greater than that in early CRRT patients [(1178.81 ±397.03) mLvs.(287.22 ± ± 433.53) mL,P =0.00] and the lung oxygenation index in late CRRT patients was significantly worse thanthat in early CRRT patients [(211.22±42.56) vs.(169.46±57.40),P=0.04] (3) The relevant variables to 28-day mortality in AKI patients with severe sepsis included CRRT treatment,oxygenation index and the average daily fluid balance ＞ 500 mL.Among them,fluid balance ＞ 500mL was an independent risk factor for AKI patients with severe sepsis.Their prognosis was worse if they had greater positive fluid balance.CRRT was the protective factor which could affect the prognosis of patients with severe sepsis complicated by AKI.Conclusions Patients with severe sepsis complicated by AKI has a high mortality.Persistent fluid overload can lead to increased mortality in patients with severe sepsis complicated by AKI.Early CRRT can reduce fluid retention in patients with renal failure and improve oxygenation index.

Objective To evaluate clinical effect and safety of direct hemoperfusion with neutral resin (NS-DHP) on patients with septic shock caused by Gram-negative bacteria infection.Methods A total of 42 patients were enrolled in the study and randomly ( random number) divided into two groups.Patients of control group ( n =24) received sepsis bundle therapy,and patients of group D ( n =18 ) were treated with NS-DHP in addition to sepsis bundle therapy.HA330 hemoperfusion device were used in each patient of group D.The procedure of hemoparfusion lasted 2.5 hours and carried out trice a 24 hours.Clinical data including APCHE Ⅱ score,PO2/FiO2 (OI),mean arterial pressure (MAP),dopamine usage (DA),plasma level of endotoxin (ET),C-reactive protein (CRP),TNF-α,IL-6 and IL-10 were recorded during the treatment.Results Patients well tolerated NS-DHP without any complication in group D.All patients in both two groups did not receive long-term renal replacement therapy.At 24 h,48 h and 72 h after the initiation of treatment,APACHE Ⅱ score,O1,MAP,DA,ET,CRP,TNF-α and IL-6 improved obviously both groups (P ＜0.05),but there was no significant ditterence in serum levels of IL-10 in both groups.In the group D,APCHE Ⅱ score,OI,MAP,DA,CRP,TNF-α and IL-6 were improved more obviously than those in the group C (P ＜0.05) ).There was no significant difference in plasma levels of ET in both groups during the treatment.Conclusions NS-DHP can improve APACHE Ⅱ score,PO2/FiO2 and MAP in patients with septic shock caused by gram-negative bacteria infection and reduce the levels of CRP,TNF-α and IL-6,but has no effect on the levels of ET and IL-10 as well as on 28-day mortality and ICU stay.

Objective To investigate and compare the change of extravascular lung water (EVLW) and levels of cytokines in septic patients without clinical acute lung injury (ALI) /acute respiratory distress syndrome (ARDS) with those in spetic patients with sepsis-induced ALI/ARDS in order to determine the role of EVLW involved in the pathogenesis of lung injury in the patients by quantifying the relationship between EVLW and biomarkers of lung injury in patients with sepsis.Methods A total of 40 septic patients complicated either with or without clinical ALI/ARDS after sepsis. In each patient,transpulmonary thermodilution (PiCCO) was used to measure cardiovascular hemodynamics and EVLWI for 7 days via an arterial cannula indwelled within 72 hours after diagnosis of severe sepsis was made, and serial bronchoalveolar lavages (BAL) were carried out.Other examinations including blood gas analysis,ventilator parameters,chest X-ray and the levels of pro-inflammatory cytokines such as tumor necrosis factor (TNF-oα),interleukin-1 in the BAL were recorded.In-hospital and ICU mortalities were also observed.Results Of total 40 patients,29 were complicated with clinically defined septic ALI/ARDS ( ARDS n =15,and ALI n =14).The septic patients complicated with ALL/ARDS had significantly higher amount of EVLWI and higher levels of TNF-α and interleukin-1 in the BAL than patients without ALI/ARDS ( P ＜ 0.05).The arterial oxygen tension/fractional inspired oxygen ratio,lung injury score,and the levels of TNF-α,IL-1 in the BAL correlated with EVLWI.Moreover,in-hospital mortality,ICU mortality and the length of ICU stay of the patients with high amount of EVLWI were markedly increased than those of patients with low amount of EVLWI. Conclusions In septic patients complicated with ALI/ARDS, the extravascular lung water index correlates with oxygenation,lung injury severity and inflammatory cytokines in lung.Determination of EVLWI may be useful for evaluation of severity of lung injury and prognosis of septic patients.

Objective To assess the efficacy and safety of tacrolimus (TAC) combined with methotrexate (MTX) for the treatment of refractory rheumatoid arthritis (RA),and to compare it with cyclophosphamide (CTX) added to MTX for the treatment of refractory RA.Methods Thirty-six cases of refractory RA patients were divided into the observation group and the control group.TAC+MTX were used in the observation group,and CTX+MTX were used in the control group.We used repeated measures to analyze the variance and Fisher exact probability method to analyze the efficacy at 8 weeks and 24 weeks.Results The effective rate of the observation group in 8 weeks,24 weeks were 77.8％(14 cases) and 100％(18 cases) respectively,while those of the control group were 11.1％ (2 cases) and 44.4％(8 cases),it showed that both TAC+MTX and CTX+MTX in the treatment of refractory RA were effective,but the efficacy of TAC+MTX was better than CTX+MTX,the difference of C reactive protein (CRP) and disease activity score (DAS)28 was statistically significant (P＜0.05),and it could significantly improve the clinical symptoms and laboratory indexes.Conclusion TAC+MTX is effective and safe in treating refractory RA,and is worth of spreading.

BACKGROUND:Stem cel transplantation has gained considerable support recently. It provides new opportunities for treating diabetic neurogenic bladder. OBJECTIVE:To summarize the research progress in bone marrow mesenchymal stem cel s (BMSCs)transplantation in the treatment of diabetic neurogenic bladder. METHODS:The first author retrieved Sciencedirect, PubMed, Embase, Wangfang and CNKI databases, for relevant articles of BMSCs transplantation in the treatment of diabetic neurogenic bladder, published from 2000 to 2016. The key words were“bone marrow mesenchymal stem cel s, diabetic neurogenic bladder, differentiation, transplantation”in Chinese and English, respectively. RESULTS AND CONCLUSION:In patients with diabetic neurogenic bladder, the transplantation of BMSCs may provide safer and longer-lasting outcomes by repairing the damaged bladder and urethra. And it can produce various bioactive substances, which wil have nutritional paracrine effects on the bladder microenvironment, including anti-inflammation, promoting cel proliferation and improving cel survival. On the one hand, the BMSCs have the ability to migrate to the injury site via the blood circulation. On the other hand, BMSCs can produce various growth factors, as wel as the cytokines that can inhibit the inflammatory response. While the current clinical studies are lacking, its efficacy and safety needs further verification.
