Objective To develop a RP-HPLC method to determine adenosine in Chongcaoqizhi granule. Method The separation was performed in a Kromasil ODS-1 column (250 mm?4.6 mm, 5 ?m) with a mobile phase of phosphate buffer solution (pH 6.5) - methanol (85∶15). The flow was 0.7 mL/min and the detective wavelength was set at 260 nm. Results The standard adenosine showed a good linear correlation at range of 1.016~12.192 ?g/mL. The linear regression equation and correlation coefficient (r) were Y =169339X -82318, r =0.9990, respectively. The average recovery of the loading was 98.02% and the RSD was 1.72%. The average content of adenosine was 12.45 ?g/g. Conclusion This method is accurate, reproducible and highly selective, and can be used for quality control of Chongcaoqizhi granule.

Objective To understand the quality of life of elders in the community of Shangqiu and analyze the affecting factors to provide a scientific evidence which could improve their quality of life.Methods The general questionnaire and World Health Organization Quality of Life Brief Evaluation From were used among 116 elders in two communities of Shangqiu.Results The quality of life of elders was in low level.The mainly factors that influencing the quality of life of elders in the community of Zhengzhou were age,education status,economic income,hobbies and interest,family relation,physical exercise.Conclusions The factors that influence the elders in community are various.To improve quality of life of elders,community workers should take relevant measures and encourage family members to participate in caring elders.

Objective To observe the influence of mental rehabilitation combined with family intervention on self -efficacy and quality of life of patients with schizophrenia.Methods 92 cases of schizophrenia patients were choosed to be the research object.They were divided into control group (46 cases)and observation group (46 cases) according to random number table method.The control group was given mental rehabilitation while the observation group was given the mental rehabilitation combined with family intervention treatment.The clinical efficacy of the two groups of patients was observed after six months.The patient's self -efficacy was assessed by using self -efficacy scale (GSES),and the patient's quality of life was assessed by using the quality of life scale (QLQ).Results Six months after treatment,the score of PANSS in patients with positive symptoms[(14.19 ±4.16)points],negative symptoms [(16.29 ±4.92)points],mental symptoms[(35.56 ±6.75)points]and total score[(65.84 ±15.83)points]in the observation group were lower,which were better than those of the control group[(17.37 ±5.27)points,(21.11 ± 5.64)points,(42.37 ±7.92)points and (80.85 ±18.83)points],and the differences were statistically significant(t =3.212,4.368,4.438,4.544,all P <0.05).The total effective rate was 86.96% in the observation group,which was significantly higher than 67.39% in the control group,the difference was statistically significant(χ2 =4.998,P =0.025).The self -efficacy scores of the two groups were higher than before the treatment,which of the observation group[(3.51 ±0.62)points]was better than that of control group[(2.13 ±0.48)points],the difference had statistical significance(t =5.593,P =0.000).After treatment,the patient's quality of life score such as emotional function [(59.82 ±11.38)points],cognitive function[(69.43 ±12.32)points],role function[(69.77 ±12.31 )points], physical function[(75.38 ±14.01 )points],social function[(66.28 ±13.03)points]and so on were higher than before treatment[(56.88 ±10.36)points,(42.01 ±9.29)points,(47.02 ±9.17)points,(60.34 ±10.89)points, (53.92 ±10.76)points].Results of the observation group were better than those of the control group[(53.07 ± 10.13)points,(63.02 ±11.17)points,(62.03 ±11.17)points,(67.33 ±11.74)points,(60.87 ±12.62)points], the differences had statistical significance(t =3.005,2.664,3.158,2.987,2.023,all P <0.05).Conclusion Therapy of mental rehabilitation combined with family intervention can improve the clinical curative effect of schizophrenia patients, and improve the patient's self -efficacy and quality of life.It is worthy of clinical popularization and application.

Objective To investigate the effect of Gangliosides on brain protection after cerebral ischemia reperfusion injury in rats. Methods The middle cerebral artery (MCA) focal cerebral ischemia /reperfusion rat models were used by thread occlusion method. The cerebral infarct volume, neurologic function deficits and neurons apoptosis in cerebral ischemic region were observed following focal cerebral ischemia 90 min (IR 0 h) and ischemia 90 min / reperfusion 24 h (IR 24 h) by injecting Gangliosides and normal saline intraperitoneally, respectively. Results A significant reduction of infarct volume was found in the Gangliosides-treated group compared with the control group. Furthermore, Gangliosides induced significant amelioration of the number of neuron apoptosis and neurologic dysfunction following focal cerebral ischemia and reperfusion in rats (all P

Objective To design a wireless monitoring system for locating oxygen supply terminals and measuring oxygen intake value of patient.Methods The locating and measuring system was built by using Mesh network of Zigbee technology and AODV algorithms based on hardware featuring MC9S08 microprocessor and MC13192.Results The oxygen supply terminals sent the location and oxygen flux information to monitoring nodes,while the monitoring server read data from all nodes in turn and save to the database.Conclusion The wireless network based on Zigbee technology can effectively monitor the utilization information about oxygen supply terminals and the value of patient oxygen intake.

Objective To investigate the potential factors affecting the survival rate of extremely low birth weight infant (ELBWI) and to make out a practical strategy. Methods Fourty-four ELBWI were devided to 3 groups according to their birth weight. All the clinical data were reviewed. Results The survival rate on discharge was 52% (22/42) and the mortality rate was 45%(19/42). The survival rate was significantly increased with higher birth weight( P
