The powder samples extracted with methanol were determined separatly at their particular absorption points using external standard method.This method had advantages of perfect separatin, high sensitivity, good reproducibility and simple operation.

Objective To investigate the relationship between body mass index (BMI) and health-related quality of life (HRQOL) in the adult Chinese population.Methods Data of 21 108 adults was collected from a cross-sectional survey performed in 9 provinces of China (Jiangsu,Anhui,Gansu,Qinghai,Fujian,Beijing,Jilin,Jiangxi and Henan province).Rank sum test was used to compare HRQOL with different BMI category.Multiple logistic regression analysis was used to assess the impact of different BMI category on HRQOL after adjusted for sex,age,marital,education,physical activity status,and tobacco and alcohol addiction.Results (1) For healthy subjects,the overweight BMI group had the highest HRQOL score in the physical component summary (PCS) (83.69±14.09) and mental component summary (MCS)(80.29± 15.41),while the underweight group had the worst HRQOL(81.20-± 14.05,74.82± 16.41).For subjects with chronic condition,overweight had the highest H RQOL score in the PCS(74.63± 18.51),and obese group had the best HRQOL in the MCS (76.75± 18.83).The variation among healthy and chronic disease subjects was much greater than the differences among BMI category groups.(2) Compared with normal weight,data on odds ratio(ORs) of impaired HRQOL in PCS(healthy subjects OR=1.23(1.10-1.35),chronic disease subjects OR=1.48(1.20-1.82)) MCS(healthy subjects OR=1.14(1.03-1.26),chronic disease subjects OR=1.37 (1.11-1.68)) and multiple dimensions increased among underweight.ORs of impaired HRQOL in PCS and general health dimension,MCS (healthy subjects OR =0.81 (0.72-0.91),chronic disease subjects OR=0.80(0.71-0.91)) and multiple dimensions decreased among overweight.ORs of impaired HRQOL in physical functioning dimension (healthy subjects OR=1.91 (1.25-2.92),chronic disease subjects OR=1.65(1.21-2.26)) while in MCS and role emotional and mental health dimension decreased among obese.Conclusion Whatever health or chronic disease,the influence of BMI on HRQOL is similar:the HRQOL score for the underweight group is significantly lower than that for other BMI groups in PCS and MCS.Overweight and the obese people has better HRQOL in MCS,and the obese people has poor physical function.The relation above between BMI and HRQOL is more obvious in people with chronic disease.

Objective To summarize the operative experience of transumbilical single-port laparoscopic cholecystectomy. Method The clinical data of 15 patients underwent transumbilical singleport laparoscopic cholecystectomy between May to October in 2010 was reviewed. Results The operative time was 30-85(45±16) min,hospitalization time was (2.5 ± 1.1 ) d. No surgical complications such as bile leak or uncontrolled hemorrhage occurred postoperatively. All the incision were healed well and the surgical scar was virtually concealed whithin the umbilicus. Conclusions Transumbilical single-port laparoscopic cholecystectomy is feasible and safe when patients are well selected. Comparing with conventional laparoscopic cholecystectomy, it's more manipulatively difficult.

Objective To investigate psychology state of AIDS-phobia population. Methods 50 AIDS-pho-bia patients and 50 healthy controls were enrolled and tested with SCL-90,EPQ, LES and social support scale. Results Scores of SCL-90 in AIDS-phobia patients are significantly more than those in controls. Scores of anxiety, depres-sion,compulsion,dread and somatization in AIDS-phobia patients are significantly more than those in controls. Scores of negative life event scale in AIDS-phobia patients are significantly more than those in controls. Scores of positive life event scale in AIDS-phobia patients are significandy less than those in controls. Scores of social support scale in AIDS-phobia patients are significantly less than those in controls. Conclusions Anxiety, depression, compulsion, dread and somatization are primary clinical manifestation of AiDS-phobia. Personal character,negative life event and lack of social support might be nosogenesis correlated with AIDS-phobia.

Objective To analyse the clinical manifestations of mycoplasma pneumoniae pneumonia(MPP) with 23SrRNA A2063G gene mutation,and improve the ability of diagnosis and treatment of patient infected with MPP.Methods MP-DNA was detected by fluorescent quantitative real-time PCR in sputum specimens from 36 children with MPP,then we detected the drug resistance gene mutation sites by nest-PCR and DNA sequencing,on this basis we classified into two groups of macrolide-resistant MP and macrolide-sensitive MP,and compared the clinical manifestations,laboratory findings,chest imagings and treatment between two groups.Results Of these 36 cases of MPP,24 cases had macrolide-resistant gene mutation with an A2063G transition in domain V of the 23SrRNA,12 cases had no macrolide-resistant gene mutation.Compared to macrolide-sensitive MP group,macrolide-resistant MP group had longer hospitalization duration,longer total cough period,longer total febrile period,longer fever duration after macrolide therapy,longer course of disease,and had higher white blood cells counts and CRP.In the macrolide-resistant MP group,the temperature subsided within 5 days after macrolide treatment alone of 12 cases,3 cases needed switch to fluoroquinolones therapy,10 cases combined with glucocorticoids and 6 cases combined with intravenous immunoglobulin,all 24 patients had good outcomes.While in macrolide-sensitive MP group,the temperature susided between 12 hours to 3 days after macrolide treatment of 8 cases.Conclusions Compared to patients infected by macrolide-sensitive MP,those mycoplasma pneumoniae pneumonia patients with 23SrRNA A2063G gene mutation have longer hospitalization duration,longer total cough period,longer total febrile period,longer fever duration after macrolide therapy,longer course of disease,and have higher white blood cells counts and CRP.Some macrolide-resistant MPP patients have good response to macrolide antibiotics treatment,while the severe cases need combined with glucocorticoids and immunoglobulin,or should change antibiotics.

AIM: To observe the therapy effect of standard prescription on ametrop amblyopia in hyperopic children.
METHODS: This study included 270 cases ( 54 eyes ) with complete data, and followed up 24mo. All the amblyopic children were given standard prescription and were divided into progressive addition glass group, under corrected group and full corrected group. And all were observed for their therapy effect and the average healing time in low hyperopic, moderate hyperopic and high hyperopic children with ametropic amblyopia respectively.
RESULTS: In low hyperopic children, the difference of the therapy effect of the three corrected methods were insignificant in two years. The meam cure time of the three corrected methods were ( 7. 33 ± 2. 11 ) mo in progressive addition glass group;(9. 0±3. 71)mo in under corrected grope;(12. 5±5. 17) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=1. 66, P>0. 05) was statistically insignificant; the difference between progressive addition glass group and full corrected grope ( t = 3. 92, P < 0. 01 ) was statistically significant; the difference between under corrected grope and full corrected grope ( t = 2. 33, P < 0. 05 ) was statistically significant. In moderate hyperopic chileren, the differences of the therapy effect of the three corrected methods were significant in two years (χ2=6. 75;P<0. 05). The difference between progressive addition glass group and under corrected grope (χ2 = 6. 3; P < 0. 01 ) was statistically significant; the difference between progressive addition glass group and full corrected grope (χ2=8. 1;P<0. 005) was statistically significant. The mean cure time of the three corrected methods were ( 14. 0±4-87) mo in progressive addition glass group; ( 16. 93±4-58)mo in under corrected grope; (17. 93±4. 42) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=2. 88, P<0. 01) was statistically significant; the difference between progressive addition glass group and full corrected grope ( t= 3. 9, P<0. 01 ) was statistically significant;the difference between under corrected grope and full corrected grope ( t = 1. 01, P > 0. 05 ) was statistically insignificant. In high hyperopic amblyopic children, the difference of the therapy effect and the healing time of the three corrected methods were insignificant in two years. (χ2=2. 43, P>0. 05. t=1. 49, P>0. 05;t=1. 46,P>0. 05;t=1. 11, P>0. 05).
CONCLUSION:Under standard prescription, application of progressive multifocal glasses provides a new effective treatment for ametropic amblyopia in hyperopic children, and makes up the deficiency of the whole straightening and under correction in clinical treatment.
