Objective To study the adsorption ability of the chitosan and the chitosan film to Cd2+. Methods Under the given condition,different time and different temperature and different beginning concentration of Cd2+, the adsorption rate and capability of the chitosan and the chitosan film were studied. Results The chitosan (or chitosan film) could adsorb Cd2+ quickly at first,however,an hour later,the adsorption rate declined slowly. Adsorption rate increased as the temperature increases. There was significant connection between the beginning concentration of Cd2+ and the adsorption rate and capability of the chitosan(or chitosan film). The adsorption rate of the chitosan (or chitosan film) even reached above 80% when the beginning concentration of Cd2+ was no more than 20 mg/L, whereas the adsorption rate and capability of the chitosan (or chitosan film) declined slowly when enhanced the beginning concentration of Cd2+. The adsorption rate and capability of the chitosan (or chitosan film) obtained a maximum only when the beginning concentration of Cd2+ was about 10 mg/L. The adsorptive ability of the chitosan film to Cd2+ was stronger than that of chitosan under the same condition. Conclusion The biosorption of the chitosan (or chitosan film) to Cd2+ fits the Langmuir equation and the adsorbability to Cd2+ of the chitosan film is stronger compared with chitosanb.

Objective To analyze the β-lactamases-producing Escherichia coli which were isolated from hospital specimens from Jun 2012 to Dec 2014,and provide a more accurate evidence to guide drug-selecting for antibacterial use.Methods An-alyzed 1 587 E.coli from patient sample selected between Jun 2012~Dec 2014 using the microbial analysis system manufac-tured by ZHUHAI DL BIOTECH CO.LTD,A phenotypic test was also conducted to test ESBLs.Results 1 587 stains of E-.coli were isolated,which counted for 23.9% of the specimens;901 stains (56.8%)out of total 1 587 stains appeared to be ESBLs-producing E.coli,and others were non-ESBLs-producing E.coli.The 1 587 Escherichia coli mainly came from De-partment of Urology (408,weight 25.7%),Department of Endocrinology (271,weight 17.1%),Department of Respiration (249,weight 15.7%).Rine specimen contributed 609 stains (47.3%),411 E.coli stains (31.9%)were discovered in spu-tum samples,and 83 stains (6.5%)showed in blood samples.The resistance to imipenem were discovered in the analysis. The rates of resistance to penicillins,cephalosporins were over 90.0%,the rates of resistance to Levofloxacin,ciprofloxacin were above 70.0%,and resistance rates to amoxicillin-clavulanic acid,Ticarcillin-clavulanic acid,piperacillin/tazobactam, amikacin were lower than 7.7%.Conclusion The drug-resistance of the E.coli were increasing over the past three years. There was a significant portion of MDR and PDR present in the trend.Thus,the reinforcement of the drug-resistance survey and testing have a far-reaching meaning to promote rational drug selecting.

Objective:To observe the effect of Chinese herbal fumigation combined with three-step tuina manipulation on concentration of endothelin (ET) and calcitonin gene-related peptide (CGRP) and vertigo in patients with vertebral artery cervical spondylosis (VACS).
Methods:A total of 120 eligible cases were randomly allocated into an observation group and a control group, 60 in each group. Cases in the observation group were treated with Chinese herbal fumigation combined with three-step tuina manipulation, whereas cases in the control group were treated with oral Flunarizine Hydrochloride Capsules.
Results: After treatment, vertigo in both groups was alleviated; there were intra-group significant differences in ET decrease and CGRP increase (P<0.01, P<0.05);and there were also inter-group significant differences (both P<0.05).
Conclusion: Chinese herbal fumigation combined with three-step tuina manipulation can regulate the levels of ET and CGRP and improve vertigo in patients with VACS. Its therapeutic efficacy is superior to oral Flunarizine Hydrochloride Capsules.

Objective To establish a statistical model that can quantitatively analyze the dosimetric sparing of the bladder based on individual patient’ s anatomy in the static intensity-modulated radiotherapy (IMRT) plans for rectal cancer.Methods Static IMRT plans (7 AP fields) for 100 rectal cancer patients were used to train the model from 2012 to 2013.The anatomical features were quantitatively analyzed by the sizes of overlap regions of bladder-planning target volume (PTV) and bladder-PTV+0.5(0.5 cm margin around the PTV) .The mathematic relationship between anatomical features and dosimetric sparing of the bladder was evaluated after the bladder sparing dose was analyzed using dose-volume histogram.The established model was verified in the IMRT plans for additional 20 rectal cancer patients.Results Bladder V50 was linearly correlated with the ratio of bladder-PTV overlap size to bladder volume ( denoted as x%) , with an equation of V50=0.89x-0.99.Bladder V40 showed an approximately linear correlation with the ratio of bladder-PTV+0.5 overlap size to bladder volume (denoted as y%).The mean dose depended on both x%and y%.For the additional 20 plans, the absolute deviation between predicted and actual values for V50 and V40 were (-3.13%-3.78%) and (-5.30%-5.66%) , respectively, and the relative deviation for the mean dose was (-3.94%-3.76%) .Conclusions The model obtained in this work provides an effective method for quantitatively estimating the bladder sparing dose in IMRT plans for rectal cancer.

Objective To investigate the influence of intraoperative posture intervention on drainage in patients after gynecological laparoscopic surgery. Methods A total of 1250 patients who were scheduled for gynecological laparoscopic surgery including laparoscopic-assisted salpingoplasty,oophorocystectomy,ectopic pregnancy,vaginal hysterectomy,myomectomy and appendectomy were randomly divided into two groups. The patients' posture was changed from Trendelenburg position to level lithotomic position during suction by the circulating nurses in the experimental group,while after surgery in the control group. The volume and time of drainage,and the length of stay after surgery were compared between the two groups. Results The volume and time of drainage,as well as the length of stay after surgery had significant differences between the two groups (P<0.05). Conclusions Intraoperative posture intervention is helpful for the treatment effect of drainage after gynecological laparoscopic surgery.
