Objective To investigate the clinical efficacy of mind-regulating and kidney-reinforcing acupuncture in treating attention deficit hyperactivity disorder (ADHD).Methods Fifty-six patients with attention deficit hyperactivity disorder were randomly allocated to treatment and control groups, 28 cases each. The treatment group received mind-regulating and kidney-reinforcing acupuncture and the control group, conventional acupuncture, for a total of 28 days. The American Connell children’s ADHD behavior diagnostic scale and the Chinese version of ADHD SNAP-IV scale-parent form were used as evaluating indicators. The total efficacy rates were compared between the two groups of patients.Results The total efficacy rate was 96.4% in the treatment group and 71.4% in the control group; there was a statistically significant difference between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the American Connell children’s ADHD behavior diagnostic scale score and the Chinese version of ADHD SNAP-IV scale-parent form score in the two groups (P<0.05). There were statistically significant post-treatment differences in the American Connell children’s ADHD behavior diagnostic scale score and the Chinese version of ADHD SNAP-IV scale-parent form score between the treatment and control groups (P<0.05). Conclusion Mind-regulating and kidney-reinforcing acupuncture is an effective way to treat attention deficit hyperactivity disorder.

Objective:To investigate the influence of MRI examination on the position of closure devices for congenital heart diseases and to assess the effect of these devices on the image quality of MRI.Methods:Two atrial septal defect closure devices, 2 ventricular septal defect closure devices and 1 patent ductus arteriosus closure device were placed into a transparent non-metal container filled with boiling agar,with the agar completely covering the devices.The agar changed into glue after cooling,then the devices were sequentially scanned by MRI in transverse and coronal planes.The changes of agar integrity,the position of devices and the image quality were observed after scanning.Results:The surface of the agar covering the devices was smooth and had no breakage after the scanning.There was no change in the shape and position of all types of devices.The coronary, transverse scanning(T_1 WI,T_2WI)showed a few slight artifacts on the central layer,all within the contour of the device.The mesh of device near the edge was clearly showed.Conclusion:Under our experimental condition,MRI does not affect the position of closure devices for congenital heart diseases and the devices do not affect the MRI image quality.

AIM To establish an animal experimental model for study on prevention of cisplatin toxicity and explore the possible mechanisms of the toxicity induced by cisplatin administration. METHODS Cisplatin was administered i.p consecutively for five days to male mice weighted from 28 to 30 g. The toxic effects induced by different doses of cisplatin on hearing, liver and kidney were determined. RESULTS Dose dependent decrease of body weight, abnormality of kidney and liver coefficients, levels of BUN and activities of ALT in serum were induced by cisplatin administration. Furthermore, Levels of GSH, activities of GSH Px and SOD increased significantly in kidney. Reversely, levels of GSH, activities of GSH Px and SOD in liver decreased and levels of LPO increased significantly in animals given cisplatin compared with those in control animals. CONCLUSION Obvious damage on hearing, liver and kidney of mice could be induced after consecutively 5 days administration of cisplatin with doses range from 3 0 to 4 0 mg?kg -1 (body weight). Oxidative damage is one of the mechanisms of these toxic effects on liver and kidney induced by cisplatin. But for different organs or at different stages of cisplatin administration, the main mechanism may be different.

FPG) /22.5.Serum adiponectin level was measured by ELISA.Results The serum adiponectin level was significantly lower in atherosclerosis group than in non-atherosclerosis and control groups(P

To study the stability of fal emulsion in all types of AU-in-One nutrient admixtures prepared from on morket fat emnlsions and new MCT/LCTs. Admixtures were prepared from domestic fat emulstions and MCT/LCTs separately with amino acids,dextrose,vitamins, electrolyltes and trace elements. They were stored for one day at 25℃ followed by one day at 25℃ and eight days at 4℃. Admixtures of control group were prepared with fat emulsions and MCT/LCTs of other manufacturers and stored under the same conditions. Particle size and distribution, mass percentage of larger particles to theroretical total iol volume were measured by using light seattering spectrophotometer and coulter multisizer accucomp. Osmolality and pH of the samples were also measured. Stability of the all-in-one admixtures was monitored. The results showe that, compare with the control products, the particle size and distribution of domestic fat emulsions and MCT/LCTs, pH and osmolality of the admixtures remained stable during observation.

Clinical skills training center of Dongyang People's hospital introduced lean man-agement conception into the resident clinical skills training. The recruited residents were grouped by degree, the training contents were detailed, and teaching plans were normalized, and small class teach-ing and real-time feedback were implemented, which improved the normalization and standardization of resident training. The implementation of lean management leads to great progress in resident train-ing, but still needs further efforts. Only in the long-term management of standardization, can lean man-agement conception be embedded in daily work, making clinical skills training center play its role in cultivating medical talents effectively.

Objective To design a kind of aseptic drainage device with safe practice and accurate measurement for clinical nurses. Methods The experiment group included 63 cases using drainage device with accurate measurement,and control group included 63 cases using disposal drainage bag with scale of visual measurement.The accuracy of drainage liquid measurement was compared between two groups,and bacterial culture was made for the drainage liquid of two groups.Results The measurement error of experiment group and control group was(3.31±1.8)mL and(56.0±5.8)mL,respectively.The difference was significant(t=-4.593,P<0.01).The bacterial culture results showed no obvious difference between two groups(positive rate were 15.9%vs 17.5%,χ2=0.057,P>0.05). Conclusion The accurately measured aseptic drainage device is convenient for nurses to practice in clinics,and its application can reduce workload of nurses and decrease the occurrence of pollution.

Objective To investigate the effects of remifentanil on large-conductance Ca2+ -activated potassium channel (BKCa) in human mesenteric arterial smooth muscle cells (MASMCs) and the mechanism of the vasorelaxant effect of remifentanil. Methods Human MASMCs were obtained freshly by the method of enzymolysis. BKCa current (IBKCa) was recorded by the whole-cell patch clamp technique. The changes in IBKC. produced by different concentrations of remifentanil (1.2, 4.8, 19.4, 77.4 and 310.0 nmol/L) with the holding potential of + 80 mV were observed. BKCa activation rate was calculated. Results Remifentanil significantly increased IBKCa,moved Ⅰ-Ⅴ curve upward and had no effect on the threshold of activation for IBKCa . With the increase in the concentration of remifentanil, BKCa activation rate increased gradually (P ＜ 0.01), and it remained stable when the concentration reached 19.4 nmol/L. There was no significant difference in the peak time of IBKCa after different concentrations of remifentanil were given (P ＞ 0.05). Logarithmic curve was found to suit the relationship between the concentration of remifentanil and BKCa activation rate and the IC50 concentration was (118 ± 7) nmol/L. Conclusion Remifentanil results in vasorelaxation by activating BKCa in MASMCs in a concentration-dependent manner.
