Objective To determine the curative effect of a trigeminy treatment including gen-tamycin, albumin and local oxygen therapy on treatment of ulcerative bedsore. Methods 50 cases of hospitalized patients in our hospital with ulcerative bedsore during January,2005 to December,2007 were selected. The patients were randomly classified into the experimental group and the control group with 25 patients in each group. The patients in the experimental group were treated by trigeminy treat-ment after debridement, while the patients in the control group were treated by covering with gen-tamycin and bandaging with dressing after debridement.The therapeutic effect of the two groups was compared by χ2 test. Results After the treatment, 6, 10, 6 and 3 patients in the experimental group, were healing, excellence, utility and inefficacy, respectively. On the contrast in the patients of the con-trol group, 2, 8, 5 and 10 were judged as healing, excellence, utility and inefficacy, respectively. The experimental group showed better effect than the control group. Conclusions The trigeminy treat-ment is able to remarkably increase clinical treatment effect of ulcerative bedsore.

Objective To shorten the transfer time of critical inpatients from wards to intensive care unit (ICU). Methods From Novem-ber to December, 2015, 30 critical inpatients transferred from wards to ICU were investigated, and analyzed with Six Sigma DMAIC five-step method. There were 7 main processes and 22 sub-processes refined in transfer procedure, as well as the key quality points and the factors influencing the safety of transferring. Some improvement advice were recommended, including multifunctional transfer cart, Check-list before Transfer to Intensive Care Unit for Critical Patients, setting up transport group, training for young nurses and application of SBAR communication. Other 30 critical inpatients transferred from wards to ICU, from May to June, 2016, after the series of control pro-grams, were investigated. Results After improvement, the total transfer time from wards to ICU decreased (t=15.052, P<0.001), without the increase of human power and unsafety issues. The rescue success rate increased from 91.67%to 98.01%. Conclusion The process transfer-ring patient from wards to ICU has been reengineered based on Six Sigma DMAIC management, that reduces the time and improve the res-cue success rate.

Objective To investigate condition of single drug or multiple drug resistance and sensitivities of different combinations of antibiotics in Helicobacter pylori (H.pylori) infected patients of different ages in Jiaxing City,Zhejiang Province.Methods From January 2007 to December 2011,a total of 6280 patients underwent gastroendoscopy examination were enrolled,the average age of them was 50.8 years old.Among them,129 cases were less than 20 years old,1802 cases were between 20 and 40,3016 cases were between 40 and 60,and 1333 cases were over 60.The mucosa of gastric antrum was collected for H.pylori culture.Drug sensitivity of isolated H.pylori strains was tested with metronidazole,amoxicillin and gentamycin,furazolidone,clarithromycin and levofloxacin.x2 test was performed for the comparison of drug resistance among different age groups.Results Among 6280 specimens,H.pylori culture of 2311 cases was positive (positive rate 36.80％).The positive rate of patients aged between 40 and 60 was the highest (38.43％,1159/3016),and that of patients over 60 was the lowest (33.76％,450/1333).The drug resistance rate of metronidazole in patients between 20 and 40 years reached 98.02％ (644/657) and was the highest.The drug resistance rate of clarithromycin in patents over 60 years old was the highest,which was 22.67％(102/450).The drug resistance rates of the levofloxacin,furazolidone,amoxicillin and gentamicin were low of all ages.Mixed resistance of two antibiotic appeared in 586 strains,mixed resistance rate of metronidazole and clarithromycin was the highest (259 strains,15.23 ％).Mixed resistance of three drugs appeared in 49 strains,mixed resistance rate of metronidazole,clarithromycin and levofloxacin was the highest (32 strains,12.88％).A total of 1691 strains were sensitive to the combination of amoxicillin and gentamycin,the sensitive was rate 99.41％.The sensitive rate of the combination of amoxicillin and furazolidone,gentamycin and furazolidone was both 94.24％.Conclusions Metronidazole presented high drug resistance of all ages,and should not be chosen.The combination use of amoxicillin and gentamicin is the ideal antibiotic combination for different ages.The combination of gentamycin and furazolidone is recommended for patients who are allergic to penicillin.

Background:Resistance of Helicobacter pylori(Hp)to antibiotics is the primary reason for failure of Hp eradication therapies. It has been reported that there are regional differences in the resistance rate of Hp to commonly used antibiotics. Monitoring the regional Hp resistance status is helpful for improving the eradication rate in local area. Aims:To investigate the resistant spectrum of clinical Hp strains to commonly used antibiotics in Jiaxing Area,Zhejiang Province. Methods:A total of 17 402 patients who underwent gastroscopy from Jan. 2009 to Dec. 2013 at Jiaxing First Hospital were recruited for Hp culturing by using gastric antral biopsies. Then a drug sensitive test was performed for the Hp strains obtained from the culturing. Sensitivity of these Hp strains to metronidazole,amoxicillin,gentamicin,furazolidone,clarithromycin and levofloxacin was determined. Results:Among the 17 402 cases of gastric antral biopsies,5 898(33. 9% )were positive for Hp culturing. Drug sensitive test revealed that the resistance rate of metronidazole was extremely high in all year and age groups;the resistance rates of clarithromycin and levofloxacin were increasing by years;and the resistance rates of furazolidone,amoxicillin and gentamicin were considerably low in all year and age groups. When two antibiotics were combined,amoxicillin and gentamicin accounted for the lowest resistance rate,and the next were amoxicillin and furazolidone,and gentamicin and furazolidone,respectively. Conclusions:The clinical Hp strains isolated from all age groups in Jiaxing Area,Zhejiang Province are highly resistant to metronidazole,therefore it is not recommended to be used in first line eradication regimen. Amoxicillin combined with gentamicin/ furazolidone is an ideal antibiotic combination for patients with Hp infection in all age groups;and combination of gentamicin and furazolidone is recommended to patients who are allergic to penicillin.

OBJECTIVETo investigate the relationship between the environmental tobacco smoke (ETS) and lung cancer by Meta-analysis.

METHODSWe used "lung cancer/lung neoplasm", "non-smoking/non-smoker", "China/Chinese", "case-control/case control", "risk factor", "environmental tobacco smoke/passive smoking" as key words, to search papers in databases including Chinese BioMedical Literature (CBM), China National Knowledge Internet (CNKI), Wanfang, Vip Citation Databases (VIP), PubMed and Web of Science databases, and collected the case-control studies on ETS and lung cancer among Chinese non-smokers from January 1999 to December 2013. A total of 129 research papers were collected. RevMan 5.2 software was used to calculate combined odds radio (OR) and 95% CI.

RESULTSQualified 18 literatures were included, total cases 6 145 and controls 8 132. Consolidated results showed that ETS exposure could increase the risk of lung cancer, combined OR (95% CI) = 1.52 (1.42-1.64). Stratified analysis showed that ETS exposure was found to be significantly associated with an increasing risk of the lung cancer on non-smoking women and men, and combined OR (95% CI) were 1.58 (1.42-1.75) and 1.34 (1.08-1.65), respectively; the ETS exposure from family or the working environment could increase the risk of lung cancer, and combined OR (95% CI) were 1.48 (1.20-1.82) and 1.38 (1.13-1.69) respectively; childhood exposure and adult exposure were no significant statistical significance, and combined OR (95% CI) were 1.37 (0.98-1.91), and 1.34 (0.97-1.85) respectively.

CONCLUSIONEnvironmental tobacco smoke exposure was a significant risk factor of lung cancer among non-smokers in China.

Objective: To analyze the interactions between different structural types of volatile oil components (VOCs) and skin lipid molecules, and investigate the mechanism of volatile oil in Chinese materia medica (VOCMM) as penetration enhancers. Methods: In this study, 210 different structural types of VOCs were selected from the VOCMM penetration enhancer database, and the molecular docking experiments were conducted with three main lipid molecules of skin: ceramide 2 (CER2), cholesterol (CHL), and free fatty acid (FFA). Each VOC was docked individually with each lipid molecule. Cluster analysis was used to explore the relationship between the binding energy of VOCs and their molecular structures. Nine specific pathogen-free (SPF) Sprague Dawley (SD) rats were randomly divided into Control, Nootkatone, and 3-Butylidenephthalide groups for in vitro percutaneous experiments, with three rats in each group. The donor pool solutions were 3% gastrodin, 3% gastrodin + 3% nootkatone, and 3% gastrodin + 3% 3-butylidenephthalide, respectively. The penetration enhancing effects of VOCs with higher binding energy were evaluated by comparing the 12-hour cumulative percutaneous absorption of gastrodin (Q12, µg/cm²). Result: (i) Most of the VOCs were non-hydrogen bonded to the hydrophobic parts of CHL and FFA, and hydrogen bonded to the head group of CER2. Among them, sesquiterpene oxides showed the most pronounced binding affinity to CER2. The VOCs with 2 − 4 rings (including carbon rings, benzene rings, and heterocycles) demonstrated stronger binding affinity for three skin lipid molecules compared with the VOCs without intramolecular rings (P < 0.01). (ii) According to the cluster analysis, most of the VOCs that bond well to CER2 had 2 − 3 intramolecular rings. The non-oxygenated VOCs were bonded to CER2 in a hydrophobic manner. The oxygenated VOCs were mostly bonded to CER2 by hydrogen bonding. (iii) The results of Franz diffusion cell experiment showed that the Q12 of Control group was 260.60 ± 25.09 µg/cm2, and the transdermal absorption of gastrodin was significantly increased in Nootkatone group (Q12 = 5 503.00 ± 1 080.00 µg/cm², P < 0.01).  The transdermal absorption of gastrodin was also increased in 3-Butylidenephthalide  group (Q12 = 495.40 ± 56.98 µg/cm², P > 0.05). (iv) The type of oxygen-containing functional groups in VOCs was also an influencing factor of binding affinity to CER2. Conclusion The interactions between different types of VOCs with different structures in the VOCMM and three skin lipid molecules in the stratum corneum were investigated at the molecular level in this paper. This research provided theoretical guidance and data support for the screening of volatile oil-based penetration enhancers,  and a simple and rapid method for studying the penetration-enhancing mechanism of volatile oils.
