Objective: To investigate the therapeutic effect of Back-Shu acupoint in treating asthma. Methods: Sixty-one patients were randomly divided into a Back-Shu acupoint group, a acupuncture-moxibustion group and a acupuncture group. All the three groups were treated twice a week, 10 times made up a treatment course. The therapeutic effect was evaluated after three courses of treatment. Results and conclusion: The control and marked effective rate were significantly higher in the Back-Shu acupoint group and acupuncture-moxibustion groups than in the acupuncture group (P<0.05). They were slightly higher in the acupuncture-moxibustion group than in the Back-Shu acupoint group, but there was no statistically significant difference. The results indicated that the Back-Shu acupoints have a good therapeutic effect in treating asthma.

Objective To investigate the clinical efficacy of atorvastatin in patients with lacunar infarctions (LI) and influence on cerebrovascular reactivity(CVR). Methods 60 patients with LI were randomly divided into observation group and control group. The patients of control group were given aspirin treatment, patients of observation group were given atorvastatin combination with aspirin therapy. The breath-holding index(BHI) before and after treatment was calculated. After continuous treatment for 3 months the clinical efficacy was evaluated. Results The total effective rate of the observation group was 90. 0% ,it was significantly higher than that of the control group(73.3% ),compared with the control group the difference was significant( x2 = 10. 428 ,P < 0. 05). The bilateral BHI of observation group significantly increased, compared with per-treatment and control group the difference was significant ( t =9. 455,6. 135 ,all P < 0. 05 ) ,but the bilateral BHI of control group had no significant difference compared with pertreatment ( P ＞ 0. 05 ). Conclusion Atorvastatin could effectively improve CVR in patients with LI. Therefore, atorvastatin had great significance for the prevention of stroke.

Objective:To provide more details and guide the management and usage as well as purchasing for medical equipment, so as to realize the optimization and utilization of the medical resources and impel Precision Medicine Initiative.Methods:The cost-effective analysis and the rate of return analysis of two large-scale precision equipments (MRI and Fundus camera usage) during January 2015 and June 2016 were performed. Besides, the equipment cost was divides into several more detailed projects in the research.Results: The rate of return of MRI in the first half year of 2016 was 8.5%, which was obviously higher than the one of 2015 which was 4.1%; the rate of return of Fundus camera usage in the first half year of 2016 was 25.9%, which was also obviously higher than the one of 2015 that was 15.0%. In the analysis, the depreciation of equipment was the main cost.Conclusion: It was critical and necessary to strengthen the standardized operation and routine maintenance in operation, in order to improve their safety usage rate.

Objective To prepare the PLGA nanoparticles( NPs) loading tetrandrine, investigate in vitro drug release behavior. Methods Tetrandrine loaded PLGA NPs were prepared by the emulsion solvent diffusion method and the preparation process was optimized by changing the stabilizer concentration and emulsion energy. The drug loading and entrapment efficiency were studied to evaluate the drug-loading property.The influence of particles size and pH value of release media on drug release behavior was investigated. Results Nanoparticles in the mean size of(203.4±2.8)nm had spherical shape and showed negative surface charge.Drug loading and entrapment efficiency was(2.17±0.10)% and(67.88±4.27)%, respectively.Tet-PLGA NPs retarded drug release in vitro, the cumulative release percentage was increased with the particle size increasing and it in acidic release medium showed a higher drug release amount. Conclusion Tetrandrine loaded PLGA nanoparticles have good entrapment efficiency, uniform particle size and can retard drug release in vitro.

Objective To investigate the clinical value of the bedside color Doppler in the assessment infants with periventricular-intraventricular hemorrhages (PIVH).Methods Sixty-eight cases of PIVH newborns and 156 healthy newborns were involved in the study,dynamic monitoring were undergone within a week after birth.The middle cerebral artery(MCA) hemodynamic parameters of velocity systolic (Vs),velocity diastolic(Vd) and resistance index (RI) were recorded,and the differences of the parameters were compared between different grades as well as those of the normal newborns at 1 d,4 d and 7 d after born.Results Total 68 PIVH infants were diagnosed by bedside color Doppler accurately.Prevalences of premature and low birth weight infants were higher than term infants and normal birth weight children,respectively (P ＜0.05).Vs and Vd of 4 groups of children with PIVH showed an increasing trend in a week after born.The differences of Vs between grade Ⅰ and normal newborns in 4 d and 7 d were not statistically significant (P＞ 0.05),the differences of the other three groups compared with normal newborn group in1 d,4 d and 7 d were statistically significant (P ＜0.05).Vd of grade Ⅱ newborns within 7 d were greater than those of other 4 groups (P ＜0.05),grade Ⅲ and grade Ⅳ within 7 d were less than healthy newborns (P ＜0.05).The difference of RI between all groups were not statistically significant (P ＞ 0.05).Conclusions The diagnostic accuracy rate of PIVH by bedside Doppler is high and the dynamic monitoring of neonatal hemodynamics could provide an important basis for assessing the occurrence and development of PIVH.

Objective To study the effect of model nurse election on satisfaction degree with nursing. Methods A model nurse election group was set up to carry out objective assessment, recommendation from doctors, nurses and patients, and feedback. The results in the satisfaction of doctors, nurses and patients were compared between before and after the activity. Results The satisfaction rate of doctors , nurses and patients after implementation of model nurse election were all significantly higher than before the implementation (P<0.05). Conclusion model nurse election used in the nursing management can help to improve nursing management effectiveness, drive continuous improvement of nursing quality, build harmonious doctor-patient relationship, and ultimately enhance satisfaction of doctors, nurses and patients.

Objective To evaluate the accuracy of monitoring the neuremuscular blockade intraoporatively by transcutaneous electrical stimulation at the P6 acupuncture point. Methods Thirty-five patients, ASA Ⅰ - Ⅲ, BMI≤35 kg/m2 scheduled for abdominal surgery were selected. Anesthesia was induced by sufentunil 0.2-0.3 μg/ kg iv, propofol 2,5-3.5 mg/kg iv. Neuromuscular monitoring was performed by TOF Watch SXR at the P6 acupuncture point on the left forearm and ulnar nerve on the right. The current intensity and gain were recorded frem all the patients;onset time, recovery time of TOF ratio 25% and TOF ratio 90% of atrucurium were also obtained by TOF stimulation on the P6 acupuncture point and the ulnar nerve in patients who were administered a single bolus of atracurium 0.5 mg/kg iv during operation. Controlled ventilation commenced after endotracheal intubation. Results There were no significant differences between the P6 acupuncture point and the ulnar nerve in stimulus intensity or gain ( P > 0.05 ). There were no significant differences between the P6 acupuncture point and the ulnar nerve in onset time, recovery time of TOF ratio 25% and TOF ratio 90% (P > 0.05).Conclusion Transcutaneous electrical stimulation at the P6 acupuncture point can be used to monitor neuromuscular blockade intraoperafively.

Objective To study CT diagnostic value of benign and malignant salivary gland lesions.Methods CT features in 36 cases with pathologically-proved salivary lesions were retrospectively analyzed.There were 19 cases with benign tumors,5 cases with chronic inflammation,1 case with tuberculosis and 11 cases with malignant tumors.Results Benign tumors were regular in 17 and well-defined in 16.All cases with chronic inflammation and 1 case with tuberculosis were regular but ill-defined.Benign lesions showed homogeneous or inhomogeneous density.Of all 11 malignant tumors,7 cases presented ill-defined margin with irregularity in shape,infiltration of adjacent subcutaneous fat tissue and disappearing of epiderm.Salivary glands enlarged and looked like "cast form" in malignant tumors.Most of the malignant tumors and benign tumors presented inhomogeneous density.Conclusion CT scan is of important value in the diagnosis of salivary diseases.
