Objective:To prepare the ocular thermosensitive gel of atropine sulfate and study its in vitro release. Methods: The gel formula was optimized by central composite design response surface methodology. The influences of the amounts of poloxamer 407 (P407) and poloxamer 188(P188) on gelling temperature before and after the dilution with simulated tear fluid were investigated. A membraneless dissolution model was used to determine the gel erosion and in vitro release. Results:The optimized gel formula was as follows:23% P407 and 5% P188. The deviations between the measured values and predicted values were all lower than 5%. The in vitro release experiment showed that the gel erosion and the drug release fitted zero-order kinetics equations with promising correlation, indicating a dissolution-controlled release mechanism. Conclusion:The optimization of the ocular thermosensitive gel of atropine sul-fate can be achieved by central composite design response surface methodology with good estimation. The thermosensitive gel with sus-tained drug release property meets the design requirements.

Objective:To study influence of intravenous injection urapidil and nitroglycerin micro pump on blood pressure and heart rate (HR) of hypertension patients undergoing tooth extraction.Methods:116 hypertension patients underwent electrocardiographic monitoring tooth extraction in our hospital from January 2015 to October 2016 were enrolled in this study.According to the random number table method,the patients were divided into observation group and control group with 58 cases,the control group was given nitroglycerin plus pump static point to maintain,the observation group was given intravenous urapidil and pump maintenance,compared the changes of systolic blood pressure (SBP),diastolic blood pressure (DBP) and HR in two groups before operation,at anesthesia,10min after anesthesia,in operation,10 min after operation,and compared the adverse reactions condition of the two groups.Results:The levels of SBP and DBP in two groups in operation and 10 min after operation were significantly lower than that before operation,and the SBP and DBP levels in the observation group in operation were significantly lower than control group,the differences were statistically significant (all P＜0.05).The HR in control group in operation,10 min after operation were significantly higher than before operation,while the observation group were significantly lower control group,the differences were statistically significant (P＜0.05).The total incidence of adverse reactions in the observation group was 6.90％(4/58),which has no significant difference than 10.34％ (6/58) in control group (P＞0.05).Conclusion:Intravenous injection urapidil has little effect on blood pressure and HR in hypertension patients undergoing tooth extraction,and with good safety,which is worthy of promotion.

Objective To explore one mechanism of therapeutic action of electroacupuncture on Alzheimer’s disease (AD), that is, improving the way to eliminate cerebral microvascular Ab by investigating the effect of electroacupuncture on hippocampal microvascular Ab deposition and learning and memory abilities in APP/PSI double transgenic mice. Method Twenty-four 7-month-old male APP/PSI double transgenic mice were randomized into model and electroacupuncture groups, 12 mice each. Same sex transgene-negative littermate mice (12 mice) constituted a blank control group. The electroacupuncture group received electric acupuncture at points Baihui (GV20) and Yongquan (KI1), 15 min once every other day, for a total of six weeks. After treatment, mouse learning and memory abilities were tested using the Morris water maze. The expressions of Ab 1-40 and Ab 1-42 in the hippocampal microvascular wall and senile plaque were determined by immunohistochemical method. Hippocampal microvascular Ab-positive expression was semi-quantitatively analyzed using the Imagine Pro Plus software. Result The Morris water maze test showed that escape latency lengthened (P<0.05), and the number of crossing platform and swimming time in the platform quadrant decreased (P<0.05) in the model group compared with the blank control group. Escape latency shortened (P<0.05), and the number of crossing platform and swimming time in the platform quadrant increased (P<0.05) in the electroacupuncture group compared with the model group. The immunohistochemical results showed that hippocampal microvascular Ab 1-42 and Ab 1-40 integral optical densities were higher in the model group than in the blank control group (P<0.05) and senile plaques appeared in the hippocampus. Hippocampal microvascular Ab 1-42 and Ab 1-40 integral optical densities were lower in the in the electroacupuncture group than in the model group (P<0.05). Conclusion Electroacupuncture reduces mouse learning and memory impairments and hippocampal microvascular Ab deposition. Its mechanism may be that electroacupuncture improves the way of eliminating cerebral microvascular Ab to decrease cerebral Ab deposition.

Objective To understand the status quo of the illness situation and the implementation of prevention and control measures on Kashin-Beck disease( KBD ) in Shandong Province , and provide a scientific basis for assessment and acceptance of the work on eliminating KBD. Methods In accordance with the requirements of the national “Implementation Scheme for Endemic Disease Control in 2012” and the “Shandong Provincial Technical Scheme for KBD Control in 2012”. In four towns of Qingzhou, three epidemic villages were selected as the surveying villages in each town in order to understand the implementation of measures for prevention and control of KBD; information such as population of investigating villages, per capita income, farming, food and the implementation of control measures,etc were included. In each investigating village, 7 - 12 years old children were selected to receive clinical and X-ray examination. When fewer than 50 people in a investigating village , one additional endemic village was included near the investigating village , and all children aged 7 to 12 of the village were checked. The number of cases of clinical degree Ⅰ, Ⅱ, Ⅲand the detection rates, X-ray positive detection rate, the number of cases of metaphysis, epiphysis, distal end of phalanx, carpal bone, triad and the detection rates were calculated, respectively. Clinical and X-ray diagnosis were based on “The Diagnostic Criteria of Kaschin-Beck disease”(WS/T 207-2010). Results A total of 14 epidemic villages were selected to survey in four towns of Qingzhou. In the recent three years in the epidemic areas, measures of supplying Se had not been implemented;measures of resettlement and off-site education had not been implemented either. In the epidemic areas , the main crops were wheat and corn; the staple food was flour which accounted for more than 80%, and the foreign food bought accounted for only 11%. The areas of returning farmland to forest (grass) accounted for 0.32%(36/11 151) of the original arable land, and the areas of replanting economic crops accounted for 1.17%(131/11 151) of the original farmland. A total of 536 children aged 7 to 12 were examined by clinical and X-rays. Patient of KBD was not detected clinically. Six positive patients with metaphyseal changes of KBD were detected by X-rays, and the average X-ray detection rate was 1.12%(6/536). Patients with abnormal epiphysis, distal end of phalanx and carpal bone were not detected by X-rays. Conclusions KBD in Shandong Province has been effectively controlled. Since the cause of KBD is still unknown, it is necessary to build a sustainable long-term control mechanism of KBD;further improve the monitoring system and dynamic monitoring work still need to be strengthened.
