Objective To investigate the discharge outcome and its clinical influential factors of acute poisoning in children, and to provide the clinical references for prevention. Methods Questionaire about acute poisoning in children made by the research group,the hospitalized children and the influential factors were analyzed according to the outcome. Results Among 168 cases of acute poisoning hospitalized children,the curative rate was 80.95%, 16 cases(9.52%) were improved,6 cases (3.57%)were quitted,1.20% was ' not curative' and 4. 76% died. The factors including age,treatment time, route of entry, varieties of poison, medical examination of admission were statistically associated with the discharge outcome.Conclusion The outcome can be improved through an intensive nurse of the children under the age of three and early treatment. The cases who were not poisoned by the invasion of gastrointestinal tract,paraquat poisoning,and those with abnormalities of breathing, pupilla, awareness in medical examination of admission would have poor discharge outcomes, and should be monitored closely and treated timely.

This study examined the effects of a combined surgery of sleeve gastrectomy (SG) and modified jejunoileal bypass (JIB) on the body weight, food intake, and the plasma levels of active glucagon-like peptide-1 (GLP-1) and total ghrelin of rats. Rats were divided into 3 groups in terms of different surgical protocol: SG-JIB (n=12), SG (n=12), JIB (n=12) and sham surgery groups (n=10). In SG-JIB group, rats was subjected to sleeve gastrectomy and end to side anastomosis of part of the jejunum (25 cm from the ligament of Treitz) to the ileum 25 cm proximal to the cecum. The body weight and food intake were evaluated during 10 consecutive weeks postoperatively. The levels of active GLP-1 and total ghrelin in the plasma of the rats were measured by ELISA assay. The results showed that the SG-JIB treated rats relative to SG- or JIB-treated ones produced a sustained reduction in food intake and weight gain. The level of active GLP-1 was elevated and total ghrelin level decreased in SG-JIB-treated rats as compared with SG- or JIB-treated ones. It was concluded that SG-JIB could efficiently reduce the body weight and food intake, alter obesity-related hormone levels of the rats, indicating that SG-JIB may be potentially used for the treatment of obesity.

Objective To investigate the effect of ethanol on level of the main hippocampal subtype of muscarinic receptor(M1)in mice,and evalu?ate whether the content change on this receptor could be linked with alterations in cognition,so as to further reveal the mechanism of brain damage in?duced by ethanol. Methods Sixty female mice were randomly divided into four groups. The model mice were induced by intragastric administration of ethanol at dose of 8%,16%,and 32%respectively of 0.2 mL/10 g for 8 weeks according to the protocol,and control group were treated with intra?gastric administration of distilled water. The capability of learning and memory were examined by Morris water maze,and ELISA method was used to measure the M1 receptor content in hippocampus in each group of mice. Results Compared with first day,the mean escape latency period on the fifth day was significantly shortened in each group. There was no significant difference between ethanol and control group for the mean escape latency period on the fifth day. Compared with the control group,the active time in the target quadrant was significantly shortened in 16%and 32%ethanol group. M1 receptor content in hippocampus formation was significantly decreased in all the ethanol group mice. The ethanol concentration was nega?tive correlated with the M1 receptor content. Conclusion Chronic alcoholism can induce the memory impairment in mice,which might be associat?ed with the low level of M1 receptor subtype in hippocampus of mice.

OBJECTIVE:To provide reference for improving the service quality of outpatient pharmacy in hospital. METH-ODS:A questionnaire survey was conducted to investigate and analyze the patients’satisfaction and related influential factors to outpatient pharmacy in a third grade class-A hospital in Chengdu. RESULTS:Totally 165 questionnaires were sent out,and 150 were effectively received with effective recovery of 90.91%. The total score for patients’satisfaction was (44.67 ± 7.81) scores, and the rate of satisfaction was(81.22±14.19)%. The top three entries were“the will you choose to come to our hospital again if necessary”,“the notices about time and place for taking the medicine”and“the overall evaluation of the professional ethics of med-ical staff”,scored 4.38,4.25 and 4.25,respectively;the last three entries were“waiting time for taking medicine”,“the notices about how long it takes to take the medicine”and“service facilities and environmental facilities for drug taking”,scored 3.55, 3.63 and 3.95,respectively. The top three suggestions were“long waiting time for taking medicine and inconvenient”,“noisy envi-ronment,bad order”and“expensive drugs charges but less reimburse”. The univariate analysis and multivariate analysis showed that gender,age,marital status,education,occupation,family income per month,resident,drug taking times and payment etc. factors showed no significant effects on patients’satisfaction scores(P>0.05). CONCLUSIONS:The degree of patients’satisfac-tion in outpatient pharmacy have no obvious specificity and preference,the key to improve the degree of satisfaction lies on strengthening the service of the hospital and the perception of the patients. While the next research will focus on how to find the breakthrough points and key points to improve the experience of waiting,standardize process management and logistics manage-ment,and make patients aware of the service development.

This study is to prepare the in situ forming sustained-release injection which can perform sustained release behavior at the periodontal site for 7 days and to evaluate its in vitro and in vivo properties. After preparation of in situ forming sustained-release injection the in situ time was studied. And the surface of the solid injection was characterized by SEM. The rheological curve at 0 degrees C, 25 degrees C, 37 degrees C was determined and the impact of the temperature on the viscosity was examined. The in vitro release behavior was investigated. At last, rabbit periodontitis model was established to study its pharmacokinetics. The injection was stable, hard to stratify and decompose. The in situ forming time was about 6 seconds. It can easily adhere into periodontal pockets. There were lots of holes on the surface of the solid injection for the drug to diffuse. The drug releasing curves could be fit by Korsmeyer-Peppas equation. The drug smoothly released for 7 days at pH 7.4 PBS buffer with a very slight burst release and maintained a certain concentration. In vivo pharmacokinetics results indicated that after administration with the in situ forming injection, achievement of tinidazole (TNZ) concentration in gingival crevicular fluid (GCF) was more comparable and long-lasting than usual solution of TNZ management and relatively constant TNZ levels were attained until 168 h. All these results supported the prospect of tinidazole in situ forming sustained-release injection in clinical applications.

Objective To construct and analyze the model of the sleeve gastrectomy with modified jejunoileal bypass (SG/MJIB) on non-obese Goto - kakizaki (GK) rats. Methods GK rats were randomly divided into SG/MJIB, sham-SG/MJIB, pair-fed (PF) and controls group. Before and after surgery, the changes of weight, food intake, fasting glucose, oral glucose tolerance test (OGTT), insulin tolerance test (ITT), fasting plasma Insulin and the histological changes in islet were dynamically observed for 16 weeks. Results From the 4th week postoperative, the weight changes of SG/MJIB significantly decreased compared with sham-SG/MJIB and PF group (P＜0.01). Fasting glucose concentration of SG/MJIB animals was lower than sham-SG/MJIB, PF and controls group (P＜0.05). The OGTT of SG/MJIB rats was obviously improved compared with the sham-SG/MJIB, PF and controls group （P＜0.01). Two weeks after operation, glucose tolerance was better improved in SG/MJIB than preoperative, the area under the curve (AUC) of blood glucose concentration decreased by about 38.9% (P＜0.01). Postoperative insulin levels in SG/MJIB group were obviously lower than sham-SG/MJIB group throughout the experiment(P＜0.05). In the 16th week, the morph of pancreatic islet of SG/MJIB was obviously improved. In the SG/MJIB group, the number of positive β-cell and mature acinus was significantly increased, while sham surgery groups had no obvious changes as mentioned above. Conclusions SG/MJIB was directly linked to the reduction in glucose levels in GK rats, independently weight loss and caloric intake, and it can be served asa stable long-lasting hypoglycemic surgery model to research the mechanism for the treatment of type 2 diabetes.
