Objective To observe the changes of body weight,fat mass and skeletal muscle mass of rats after 4 weeks of intermittent fasting,and explore relationship with autophagy in skeletal muscle,so as to provide theoretical basis for intermittent fasting.Method Twenty male Sprague Dawley rats were randomly divided into a control group (Con) and an intermittent fasting group (IF),each of 10.The rats of IF group were forbidden to eat food every Wednesday and Friday,and the body weight of both groups was recorded weekly.After 4 weeks,Dual-Energy X-Ray Absorption (DEXA) was used to analyze the body fat mass,then the bilateral soleus was separated to record the wet weight and measure the cross-sectional area of the soleus fibers by testing laminin with immunofluorescence confocal laser scanning microscope.The form of autophagic vacuole of soleus was observed using a transmission electron microscopy.The expression of autophagy-related protein LC3,p62 and regulating protein AMPK,pAMPK and ULK1 were measured using Western blotting.Result After 4 weeks of intermittent fasting,the weight and fat mass of IF were significantly lower than those of Con (P＜0.01),but there were no significant differences between them in wet weight and cross-sectional area of soleus (P＞0.05).The expressions of AMPK,p-AMPK,ULK1 in IF were significantly higher than those in Con (P＜0.01).Compared with Con,the expression of LC3-Ⅱ/LC3-Ⅰ of IF increased significantly,while the expression of p62 decreased significantly (P＜0.01).Conclusion Four weeks of intermittent fasting decreases the fat mass significantly,and control the weight efficiently.Intermittent fasting can maintain the skeletal muscle mass by promoting moderate autophagy through the AMPK-ULK1 pathway.It should be a potential lose weight method for further research.

Objective To assess the efficacy of laryngeal mask airway (LMA) i-gel used in patients undergoing laparoscopic gynecological surgery. Methods Sixty ASA Ⅰ or Ⅱ patients, aged 21-64 yr, weighing 4590 kg, undergoing elective laparoscopic gynecological surgery, were randomized into 2 groups ( n = 30 each):LMA i-gel group (group Ⅰ) and LMA Supreme group (group S) . Mallampatti test was performed before operation in both groups. Anesthesia was induced with target-controlled infusion of propofol (target plasma concentration 2.5-4.0 μg/ml) and remifentanil (target plasma concentration 3-6 ng/ml) . After the patients lost consciousness, rocuronium 0.6 mg/kg was given to facilitate the LMA insertion. LMA i-gel and LMA Supreme were inserted in I and S groups respectively. A gastric tube was inserted through the drain tube of the LMA. In group S the air was injected into the cuff to make intracuff pressure reach 60 cm H2O after successful LMA insertion. The LMA placement time, the number of attempts of LMA insertion, the number of attempts of gastric tube placement, the airway sealing pressure, the parameters of hemodynamics and ventilation, and complications (sore throat, odynopliagia,hoarseness) were recorded. The fiberoptic laryngoscopy scores were assessed after successful LMA placement. The anesthesia time and recovery time were also recorded. Results There was no significant difference in the anesthesia time, recovery time, LMA placement time, fiberoptic bronchoscopy scores and the parameters of hemodynamics and ventilation between the two group. The success rates of LMA and gastric tube placement were 100% in both groups. The airway sealing pressure was significantly higher, while the incidence of sore throat and odynopliagia was significantly lower in group I than in group S. Conclusion LMA i-gel provides adequate ventilation during operation with fewer complications and can be used effectively for gynecological laparoscopic surgery.

Promotion of outstanding people to head nurses is key to hospital nursing management.In view of the current shortcomings in the analysis of appraisal data and the interpretation of appraisal results,the analysis of means(ANOM)method is introduced to the process of hospital human resource management.The proposed method aims to solve the problem when the score differences between interviewers are great and the score differences between candidates are small.An example for head nurses' promotion appraisal in a hospital is offered to demonstrate that statistical tools can provide the decision support for hospital personnel selection.Finally,the application differences between ANOM and analysis of variance(ANOVA) in human resources appraisal are compared.

Objective:To investigate the effect of genistein,a soybean-derived isoflavone,on thestimulating effect on bone resorption of IL-1?.Methods:The osteoclasts(OCs)were isolated with themethods of Yu Shifeng.The rat calvaria were cultured as an organ.The cells in the experiment weregrown in four respectively:Control(without genistein or IL-1?),10~(-6) mol/L genistein,10 ?g/L IL-1?and 10~(-6) mol/L genistein+10 ?g/L IL-1?.The area of bone resorption,the concentration of Ca~(2+) in thesupernatant liquid of OCs cultures and mice calvaria were tested.The contents of acid phosphatase(ACP)were also examined by biochemistry method.The index of bone resorption was counted as the ra-tio of the experiment average and control ones,which indicated the increase in bone resorption when itwas above 1.0.Results:The area of bone resorption of 10~(-6) mol/L genistein+10 ?g/L IL-1? increasedcompared with that of 10~(-6) mol/L genistein,while the concentration of Ca~(2+) in the supernatant liquid ofOCs cultures decreased significantly.The index of bone resorption of 10~(-6) mol/L genistein+10 ?g/L IL-1? lied between 10~(-6) mol/L genistein and 10 ?g/L IL-1?.In the organ culture,there was no differencein the content of ACP among all the groups,The index of bone resorption of 10~(-6) mol/L genistein+10?g/L IL-1? was below that of 10?g/L IL-1?,but both were above 1.0.The index of bone resorptionwas below 1.0 in the group of 10~(-6) mol/L genistein.Conclusion:Genistein can suppress obviously thebone resorption simulated by single IL-1?.

To evaluate the clinical efficacy and safety of Qinghouyan lozenge in the treatment of acute pharyngitis due to Lung-heat and Yin-deficiency, and compare with Qinghouyan oral Liquid. Totally 144 subjects were enrolled and randomly divided into two groups (72 in the test group and 72 in the control group). The participants in the test group were given Qinghouyan lozenge for 5 days, and those in the control group were given Qinghouyan oral Liquid for 5 days. The effectiveness evaluation indexes were pharyngalgia/odynophagia disappearance rate, overall efficacy of TCM syndromes, TCM syndrome scores, and single syndrome and sign disappearance rate. During the test, the safety was evaluated by vital sign, lab examination indexes and adverse events. The results for the full analysis set showed that the couth disappearance rate, the incidence rate of TCM syndromes, and the throat/uvula congestion disappearance rate of the test group were higher than that of the control group (P < 0.05), with significant differences in the changes in syndrome scores between the two groups (P < 0.05). Altogether 3 adverse events were observed in the test group while 6 adverse events in the control group, without significant differences in the adverse event rate between the two groups (P < 0.05), serious abnormal laboratory examinations and vital signs. In conclusion, Qinghouyan lozenge has better efficacy in treatment of acute pharyngitis due to Lung-heat and Yin-deficiency than Qinghouyan oral liquid, with good safety.

?AIM: To evaluate the effects on recovering of corneal wound and postoperative discomfort of different methods for primary pterygium.?METHODS: Forty-seven cases ( 60 eyes ) of primary pterygium were excised under microscope with limbal epithelial transplantation, with sharp dissection ( 24 cases, 30 eyes, Group A) and blunt dissection (23 cases, 30 eyes, Group B).All cases were followed up for 1d to 1mo.?RESULTS: The recovering of corneal wound was better in Group B on 1st day and 3rd day after surgery.Pain, photophobia and tears, foreign body sensation were more serious in group A on 1st day after surgery with a statistically significant difference (P=0.005,0.015,0.012). Pain, photophobia and tears, foreign body sensation were more serious in Group A on 3rd day after surgery with a statistically significant difference ( P=0.019,0.018, 0.015).There was no statistically significant difference on 1wk and 1mo after surgery (P>0.05).? CONCLUSION: Compared with sharp dissection, primary pterygium excised with blunt dissection can significantly improve recovering of corneal wound and postoperative discomfort.

Objective To study whether ferulic acid can promote healing on chronic ischemic wounds and its possible mechanisms.Methods 40 male New Zealand white rabbits were randomly divided into 4 groups:vaseline group,ischemic control group,5％ ferulic acid group and recombinant bovine basic fibroblast growth factor for external use (rb-bFGF) group.Gross wounds were carefully observed and HE staining was used to observe the wound healing and immumohistochemical staining to observe the expression of the VEGF and CD31.The RNA was extracted to detect the expression of VEGF and HIF-1a by real-time PCR.Results The general observation and the HE staining of each specimen 11 days after operation all indicated that the duration of wound healing of the 5 ％ ferulic acid group was similar to that of the rb-bFGF group and markedly shorter than the ischemic control group and the vaseline smear group.The result of the immunohistochemical staining indicated that the content of the VEGF and CD31 expression of the 5 ％ ferulic acid groups and the rb-bFGF group made lit tle difference,but there was markedly less VEGF and CD31 in ischemic control group and the vaseline smear group.The result of the PCR showed that expression level of VEGF and HIF-1α in the 5 ％ fer ulic acid group was similar to that in the rb bFGF group and the vaseline smear group,but was obviously more than that of the ischemic control group and the vaseline smear group (P ＜ 0.05).Conclusions Ferulic acid can promote angiogenesis by increasing VEGF and HIF-1α which are closely related to angiogenesis and then promote the healing of chronic wounds.
