Objective To investigate the pathogenic features and antibiotic resistance profile of nosocomial and community-acquired spontaneous bacterial peritonitis (SBP) in liver cirrhosis patients.Methods Two hundred and twenty-six cirrhotic patients with SBP who were admitted to Beijin Ditan Hospital from January 2001 to December 2008 were recruited into this study. The bacterial identification and drug susceptibility were performed. The data were analyzed by Chi square test and t test. Results Eighty-six(38.0% ) patients were diagnosed with nosocomial SBP and 140 (62.0%)were diagnosed with community-acquired SBP. The proportion of Child-Pugh Class C cases in patients with nosocomial SBP was higher than patients with community acquired SBP (97.7% vs. 82.8%; x2= 11. 489, P=0.001). Mortality rate in patients with nosocomiat SBP was also higher than patients with community acquired SBP (50. 0% vs. 30. 0%; x2 =9. 081,P=0. 003). Total 28 species (232strains) of bacteria were isolated from these patients. 77.5 % (69/89) of the nosomial SBP cases and 76.9% (110/143) of community-acquired SBP cases were caused by Gram-negative bacteria (mainly were Escherichia coli and Klebsiella pneumoniae). 19.1% nosocomial SBP cases and 21. 8%community-acquired SBP cases were caused by Gram-positive bacteria. Fungus infections accounted for 3.4% and 1.4% of these two population, respectively(P＞0.05). In patients with nosocomial SBP,19 out of 32 Escherichia coli stains and 5 out of 14 Klebsiella pneunmoniae strains were extended spectrum β-lactamase (ESBL) positive, while among 60 Escherichia coli stains and 32 Klebsiella pneunmoniae strains, only 11 Escherichia coli stains were ESBL positive (P＜0.05). The resistance rates of Gram-negative strains to cephalosporin and quinolone in nosocomial SBP patients were both higher than those in community-acquired SBP patients(P＜0. 05), but all Gram-negative isolates were sensitive to imipenem (P＞ 0. 05). No Gram-positive isolates resistant to vancomycin were found.Conclusions The liver cirrhosis patients with Child-Pugh Class C are vulnerable to nosocomial SBP and the prognosis is poor. Although the pathogenic spectrum are similar in cirrhotic patients with nosocomial and community-acquired SBP, which mainly are Escherichia coli and Klebsiella pneumoniae, the percentage of ESBL producing strains is higher in nosocomial SBP patients compared to that in community-acquired SBP patients.

AIM To investigate antitumor effects of curcumin (Cur) combining with adriamycin (ADR) on human tumor cell lines in vitro and study the mechanisms. METHODS The antitumor effects of the drugs on tumor cell lines in vitro were determined with MTT method. The Jin's formula was used to analyze the effect of drug combination. Cellular ADR accumulation was measured by fluorescence spectraphotometry. RESULTS In simultaneous adiministration Cur 4 25～34 00 ?mol?L -1 combining with ADR produced a simple addition or potentiation effect. The cellular ADR accumulation was markedly increased in the presence of Cur in MDR cells, but decreased in sensitived cells. The experiment of membrane fluidity show that that Cur affects membrane fluidity neither on KB nor on KB v200 cell line. CONCLUSION Simultaneous adiministration of Cur combining with ADR produces synergistic effect. The mechanism is connected with increasing cellular ADR accumulationon on KB v200 cell line. While on KB cell line, it is related to synergistic pharmacological effect. But the action of Cur is not connected with the change of membrane fluidity on both cell lines.

OBJECTIVE:To improve the process efficiency of automatic dispensation machine before dispensing. METHODS:After building quality control circle(QCC)in the hospital inpatient,according to the steps of QCC,the key links and factors that affect process efficiency of automatic dispensation machine before dispensing were found out,corresponding countermeasures were developed based on causes,then it was evaluated by process time and other indexes in dispensing before and after the development of QCC. RESULTS:The 2 links(removing the drug packaging,manually counting and developing add-drug list)with the longest time before dispensing improved work efficiency by setting add-drug quantity and variety truly,timing checking dispensation medi-cine,timely counting dispensation medicine drug list,strengthening training and other methods,process time of automatic dispensa-tion machine before dispensing was shortened from 179.8 min(before)to 119.2 min(after)(shortened by 33.7%),target achieve-ment rate was 168.5%;and QCC staff showed positive growth in means, responsibility, team cohesion, and other aspects (increase rate were 15%-81%). CONCLUSIONS:QCC shows obvious effect on improving process efficiency of automatic dispen-sation machine before dispensing.

The association of coagulation function with progressive proteinuria in type 2 diabetic patients was retrospectively analyzed.With increasing microalbuminuria,fibrinogen level was increased significantly.Fibrinogen was an independent risk factor of microalbuminuria. In patients as the early-stage diabetic nephropathy (DN)progressed to clinical-stage DN,the baseline level of fibrinogen was also increased [ ( 3.5 ± 0.9 vs 3.0 ± 0.6 ) g/L,P＜0.05 ].Fibrinogen may serve as a useful predictor of progressive proteinuria in type 2 diabetes.

Objective To evaluate the inhibitory effect of statins on glucose-stimulated insulin secretion (GSIS) of pancreatic islet in rat and to explore its mechanisms. Methods According to the average volume, freshly isolated or 24-hour cultured pancreatic islets were randomly divided into control group( incubated with Kreb-Ringer bicarbonate buffer), the atorvastatin group( incubated with 100 μ mol/L atorvastatin), the fluvastatin group (incubated with 100 μ mol/L fluvastatin)and the pravastatin group (incubated with 100 μ mol/L pravastatin). Stimulated by 2. 8,5. 5,11.1,16. 7 mmol/L and 25.0 mmol/L glucose respectively, the effect of 100 μ mol/L statins on ATP content and GSIS was compared in the four groups. GSIS was performed by the 37℃ bath incubation method and ATP content was measured by chemiluminescence method. Results Incubated with 100 μ mol/L atorvastatin for 30 minutes, in the presence of 16. 7 mmol/L glucose, the ATP content [(9. 54 ± 1. 64) pmol/islet vs ( 12. 33 ± 1.89) pmol/islet] and GSIS (1.60 ± 0. 21 vs 2. 39 ± 0. 30) were significantly reduced in comparison with the control group (P＜0. 05). Cultured with 100 μmol/L fluvastatin for 24 hours, the ATP content [( 10. 24 ±2.01 )pmol/islet vs (12. 31 ±2. 16) pmol/islet] and GSIS (3. 12 ± 0. 32 vs 4. 17 ±0. 37 ) were all significantly decreased at the higher glucose concentration of 16. 7 mmol/L ( P ＜ 0. 05). Conclusion Atorvastatin and fluvastatin may inhibit GSIS by decreasing ATP content in pancreatic islet and the inhibitory effect is related to the strength of its lipophilicity.

Blood lipid level and its associations with insulin resistance were studied in patients with impaired glucose tolerance (IGT).Two hundred and twenty first degree relatives of type 2 diabetes mellitus were grouped into normal glucose tolerance (NGT) and IGT groups according to results of oral glucose tolerance test.Compared with the NGT group,the IGT patients had higher serum levels of total triglyceride (TG),total cholesterol (TC),low density lipoprotein-C (LDL-C) but a lower serum level of high density lipoprotein-C (HDL-C).Homeostasis model of assessment for insulin resistance index (HOMA-IR) and area under curve of insulin (AUCI) also increased.A positive relationship was found between TG and HOMA-IR (or AUCI),but a negative relationship existed between HDL-C and HOMA-IR.In conclusion,abnormal blood lipid metabolism is present in IGT patients and it has a close correlation with insulin resistance.

Through retrospective analysis of the clinical and laboratory data of 1 466 inpatients with type 2 diabetes mellitus(T2DM),we investigated the prevalence of chronic kidney disease (CKD) and analyzed the risk factors.The prevalence of CKD in hospitalized patients with T2DM was 52.25％.In the patients with CKD,protein urine was present in 93.47％ of the cases,27.93％ of them had glomerular filtration rate(eGFR) ≤60 ml · min-1 · 1.73 m-2,damage of renal tubular function was present in 24.28％,and abnormal renal imaging in 14.88％.Logistic regression showed that age,body mass index(BMI),duration of diabetes,systolic blood pressure,serum uric acid,low density lipoprotein-cholesterol (LDL-C),and smoking were independently associated with patients of T2 DM and CKD.The prevalence of CKD was increased with aging,diabetic course,BMI,and LDL-C.CKD is a common chronic complication in patients with T2DM,especially in patients with prolonged course,advanced age,and obesity.Much attention should be paid to early detection of CKD in patients with diabetes.In addition to detecting urinary protein and eGFR,renal tubular function and morphological examination should also be included.

[Summary] To investigate the association between sleep disorder and ambulatory blood pressure rhythm in patients with type 2 diabetes. 418 patients with type 2 diabetes were divided into two groups according to Pittsburgh sleep quality index ( PSQI):patients without sleep disorder and patients with sleep disorder. Oral glucose tolerance test, insulin releasing test, and C-peptide releasing test were performed to investigate the differences in the β-cell function, the circadian rhythm of blood pressure, and blood pressure variation between the two groups after fasting and glucose-load. The correlation and regression analysis were performed between PSQI and other indicators. (1)The level of HbA1C , fasting plasma insulin, area under curve of insulin, fasting plasma C-peptide, area under curve of C-peptide, and homeostasis model assessment for insulin resistance ( HOMA-IR) were significantly higher in patients withsleepdisordercomparedtothoseinpatientswithoutsleepdisorder[(8.2±2.1)% vs(7.4±1.8)%,(13.42± 4.55vs11.86±4.52)mU/L,(8.51±0.54vs8.38±0.51)mU·L-1·min,(2.42±1.25vs1.79±0.73)ng/ml, (6.59±0.39vs6.49±0.43)μg·L-1·min,4.63±1.12vs3.86±0.97,allP<0.05]. Insulinsensitivityindex (ISI) was lower in patients with sleep disorder than that in patients without sleep disorder(-4. 26 ± 0. 78 vs-4. 05 ± 0.62,P<0.05). (2)Thelevelof24hmeansystolicanddiastolicbloodpressure,nocturalsystolicanddiastolicblood pressure, and systolic blood pressure during daytime and nighttime were significantly higher in patients with type 2 diabetes who were suffering from sleep disorder. The blood pressure variation was more marked in patients with sleep disorder. (3)Multiple stepwise regression analysis showed that PSQI score was positively related to area under curve of C-peptide, HOMA-IR, 24 h mean systolic blood pressure, and noctural systolic blood pressure (β=0. 242, 0. 293, 0. 352, 0. 413, all P<0. 05), and negatively related to ISI and decreasing ratio of noctural systolic blood pressure (β=-0. 124 and -0. 226, both P<0. 05). Sleep disorder may cause abnormal circadian rhythm of blood pressure through various mechanisms. Improving sleep disorder may help to ameliorate insulin resistance and restore normal circadian rhythm of blood pressure.

Objective To investigate the clinical status of disease self-management ability in patients with chronic hepatitis B liver fibrosis and to analyze the effect of gratitude,social support and perceived stress on the ability.Methods Totally 236 patients with chronic hepatitis B liver fibrosis were selected from Guangzhou Red Cross Hospital by convenient sampling from January 2016 to June 2017 and investigated with the general information questionnaire,the Chronic Hepatitis B Self-Management Scale,the Gratitude Resentment and Appreciation Test (GRAT),the Social Support Rating Scale and the Perceived Stress Scale-Chinese (CPSS).PASW Statistics 18.0 and AMOS 18.0 were used to analyze the effects.Results The disease self-management score in patients with chronic hepatitis B liver fibrosis was (94.41 ± 16.78).According to correlation analysis,gratitude,social support and perceived stress were positively correlated with disease self-management (r=0.327,0.339;P ＜ 0.05);while perceived stress was negatively correlated with disease self-management (r=-0.574,P ＜ 0.05).The multiple linear regression analysis and model fitting showed that gratitude had direct effect on disease self-management (β=0.314);social support had direct influence (β=0.354) and indirect (β=0.199) effect on it;and perceived stress had direct (β=-0.567) and indirect (β=-0.058) on it.Conclusions The patients with chronic hepatitis B liver fibrosis show a relatively poor disease self-management ability.Clinical medical and nursing staff shall cultivate the patients' gratitude,mobilize their social support,reduce their perceived stress and improve their disease self-management ability.

Objective:To investigate the change of the detection rate of colorectal cancer (CRC), colorectal adenoma and advanced adenoma in adults under colonoscopy in Shihezi in the past ten years.Methods:Data of patients who completed colonoscopy in the First Affiliated Hospital of Shihezi University School of Medicine from January 1, 2010 to December 31, 2019 were investigated. The medical records were collected by consulting the electronic medical record system, including the age and sex of patients and the location, quantity, size and pathological type of lesions. The detection rates, including the overall detection rate in the past 10 years, those in the first 5 years (from 2010 to 2014) and the second 5 years (from 2015 to 2019) of colorectal adenomas, advanced colorectal adenomas and CRC, were studied.Results:A total of 50 645 cases were included, 14 931 cases were excluded by the exclusion criteria, and finally a total of 35 714 cases were included in the data analysis. The 10-year overall detection rates of colorectal adenoma, advanced colorectal adenoma and CRC were 17.65% (6 302/35 714), 4.45% (1 589/35 714) and 3.71% (1 324/35 714), respectively. The overall detection rates of colorectal adenoma and advanced colorectal adenoma in the second 5 years were higher respectively than those in the first 5 years [20.33% (4 565/22 457) VS 13.10% (1 737/13 257), 4.69% (1 053/22 457) VS 4.04% (536/13 257)]. The overall detection rate of CRC in the second 5 years [3.30% (741/22 457)] was lower than that in the first 5 years [4.40% (583/13 257)].Conclusion:Compared with 2010 to 2014, the detection rate of colorectal adenoma in Shihezi area in 2015 to 2019 increased significantly, the detection rate of advanced colorectal adenoma increased slightly, and the detection rate of CRC decreased slightly. Therefore, the detection and resection of colorectal adenoma by colonoscopy may be important in reducing the incidence of CRC.
