Objective:To find out the key demand and connection point of health quality education for students of different stages by analysis of their health quality characteristics and the main contribution path, and then explore strategies to improve health quality. Methods:The stratified random cluster sampling method was carried out to select the sample population in Hangzhou. The variance analysis, curve fitting and multivariate linear regression analysis were used to analyze health quality characteristics and the main contribution path. Results:The health quality of pri-mary school students was best;the difference in quality between college students and junior high school students was not statistically significant ( P>0. 05 );and high school students had the worst health quality. The high school stage is the weakest link of health quality education. The order of the health education path and the means for improving the health quality of college, high school, and primary school students differ. With the improvement of students’ lev-el, the students that require physical quality promotion gradually decreases; the moral quality demand remains sta-ble;and the psychological quality and social adaptation ability present the tendency of a gradual increase. Conclu-sion:Student health quality shows a tendency to decreases with the rise of learning phase. The education departments should foster health consciousness and habits for students, form a healthy lifestyle behavior and ways of thinking for high school students, shape healthy personalities to improve health literacy and social adaptation abilities for college student, which is the key strategy for promoting the health quality of all-round development of the students and a-chieve the primary education goal of “health education”.

Objective:To analyse the degree of equality of New Rural Cooperative Medical Scheme (NRCMS) in different economic regions. We provide a reference for equal development of the NRCMS and the reform of the political system and mechanism under the provincial-controlled county fiscal system. Methods:A typical province was chosen with provincial-controlled county fiscal system was fully implemented several years. We collected data on coverage, financing and compensation for the NRCMS from 2005 to 2011. We used the variable coefficient, uniformity coefficient, Theil Index for comprehensive evaluation. Results:Per capita financing has not reached the bottom line. From 2005 to 2011, inter-re-gional and intra-regional variation coefficient, Theil index of service coverage, financing level and hospital actual compen-sation has declined year by year. The degree of inequality in economically developed regions was greater than in less eco-nomically developed regions and economic medium region. Conclusion:The degree of equalization of the NRCMS in the province continuously improved. Innovation of provincial-controlled county fiscal system and mechanism provides a favora-ble environment and forming conditions for equalizing the development of the NRCMS. The paper suggested exploring and building fiscal classification step transfer payment institution and dynamic prediction model of the NRCMS, further optimi-zing financing mechanism, promoting the provincial management system of the NRCMS as soon as possible in order to pro-mote the equalization development.

This study discussed how to make a cognitive behavioral therapy-orientated case formulation for the client who was diagnosed as adjustment disorder,and also the importance of the role of case formulation in guiding the whole counseling process.Four months before the client asked for psychological help,he gradually showed symptoms of depression,insomnia,work inefficiency and being suspicious of self-capacity because of the promotion and the change of supportive system.We did the psychological counseling aiming at his cognitive,emotional and behavioral problems.In addition,the Beck Depression Inventory (BDI),Beck Anxiety Inventory (BAI) and Subjective Units of Distress Scale (SUDs) were used to evaluate his emotional condition before,after and during the counseling.Results demonstrated that the client's emotional,cognitive and social functions were significantly improved,achieving the expected goals.In conclusion,the cognitive behavioral therapy-orientated case formulation for adjustment disorder could effectively guide the counseling practice.

Objective To compare the perioperative outcomes and short-term efficacy of three-port extraperitoneal laparoscopic radical prostatectomy (ELRP) and four-port ELRP.Methods Two hundred patients who had undergone ELRP for prostate cancer by a single surgeon from November 2010 to October 2014 were retrospectively analyzed.Among them,95 cases underwent three-port ELRP and 105 cases underwent four-port ELRP.On the basis of traditional four-port ELRP,three-port ELRP was characterized by the omission of the trocar on the inner side of right anterior superior iliac spine.The mean age was 66.8 ± 15.5 years,and mean total prostate specific antigen (tPSA) was 15.3 ± 12.4 μg/L.There were no significant differences including age,body mass index,tPSA,clinical stages,acceptance of neoadjuvant hormone therapy,history of transurethral resection of the prostate,history of diabetes mellitus between the 2 groups (P ＞ 0.05).Patients in three-port ELRP group had significantly smaller prostate volume than fourport group (35.6 ± 16.7 ml versus 42.2 ± 24.7 ml,P ＜ 0.05).The clinical factors as operative time,estimated blood loss,hospital stay,drainage tube keeping days,pathological Gleason scores,pathological stages,positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates were compared between the 2 groups.Results The three-port group had significantly shorter operative time than the four-port group (81.0 ± 18.6 min versus 103.6 ±34.6 min),less estimated blood loss (102.6 ±75.8 ml versus 217.5 ± 182.9 ml),less positive surgical margin rates (13.7％ versus 27.6％).There were 9 patients having Gleason scores more than 7 in the three-port ELRP group and 29 patients in four-port ELRP group (P ＜ 0.05).There were no significant differences of hospital stay,drainage tube keeping days,pathological stages between the 2 groups (P ＞ 0.05).Eighty-three cases in the three-port ELRP group (87.4％) were followed up for 5-19 months with the median time of 11 months.Ninety-two cases in fourport ELRP group (87.6％) were followed up for 17-52 months and the median time was 27 months.There were no significant differences of biochemical recurrence rates and urinary incontinence rates between the 2 groups(P ＞ 0.05).Conclusions Compared to four-port ELRP,three-port ELRP can provide shorter operative time,less blood loss,better negative surgical margin rates,similar oncological control and recovery of postoperative continence.In experienced hands,three-port ELRP could be a feasible and effective option for localized prostate cancer.

Objective To evaluate the learning curve of three-port extraperitoneal laparoscopic radical prostatectomy(ELRP) and to minimize operative time and blood loss about this procedure.Methods From August 2013 to October 2014,the data from 95 consecutive patients,who had undergone three-port ELRP for prostate cancer,were retrospectively analyzed.The mean age was 65.9 ± 7.7 years,mean total PSA level was 15.4 ± 12.7 μg/L,and mean body mass index(BMI) was 24.8 ± 3.2 kg/m2.According to the number of procedures performed by the surgeon,all patients were classified into three chronologic groups,including group A (No.1-32),group B (No.33-64) and group C (No.65-95).There were no significant differences including age,BMI,tPSA,estimated prostate volume,clinical stages,history of neoadjuvant endocrine therapy,history of transurethral resection of the prostate (TURP) among group A,B and C (P ＞ 0.05).The operative outcomes analyzed were operative time,estimated blood loss,hospital stay,drainage tube indwelling days,pathological Gleason scores,pathological stages,positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates.Among these 95 patients,the results of the first 32 cases were compared with those of the remaining 63 cases,the first 64 with the remaining 31.Results The average operative time in 95 patients was 81.0 ± 18.6 min.The sloping learning curve for this surgeon showed that the operative time for all 95 cases was strongly correlated with additional experience (| rs | =0.612,P＜0.01).Operative time,however,was not strongly correlated with the surgeon's experience in each group of A,B and C(P ＞0.05).Group A had longer operative time than that of Group B plus C(96.4 ± 11.3 min vs 73.2 ± 16.7 min,P ＜0.01).Group A plus B had longer operative time than that of group C (87.6 ± 17.2 min vs 67.5 ± 13.8 min,P ＜ 0.01).For all cases,the estimated blood loss was strongly correlated with additional experience (| rs | =0.677,P ＜ 0.01).Estimated blood loss was strongly correlated with the accumulation of experience for the initial 32 cases(| rs | =0.619,P ＜ 0.01).However,no strong correlation was observed over the next 63 cases.Group A had more blood loss than that of Group B plus C (158.7 ± 81.3 ml vs 74.1 ± 54.4 ml,P ＜ 0.01).Group A plus B had more blood loss than that of group C (125.5 ± 71.6 ml vs 55.3 ± 61.6 ml,P ＜ 0.01).But hospital stay,drainage tube keeping days were not strongly correlated with additional experience in each group(P ＞ 0.05).There were no significant correlation between the accumulation of experience and positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates.Conclusion Our experience of three-port ELRP cases appears to be favorable with decreasing tendency in operative time,estimated blood loss with experience accumulation.Exposure to 32 surgeries,operative time and estimated blood loss reduced significantly,and after 64 cases operative time and estimated blood loss further reduced.

Background The pathogenesis of age-related cataract is associated with the apoptosis of lens epithelial cells (LECs) caused by oxidative stress.Previous studies showed that intracellular focal adhesion kinase (FAK) pathway can be activated by H2O2 in vitro,which induced apoptosis of cells.To investigate the effect of oxidative on FAK expression in LECs is one of important studies in the prevention of age-related cataract.Objective This study was to investigate the expression and function of FAK in human LECs treated by H2O2.Methods Human LECs strain (HLECs-B3) were cultured in vitro in the low glucose DMEM with 10％ fetal bovine serum.Different concentrations (0,30,50,70,100,300,500,700,1000 μmol/L) of H2O2 were added into the culture medium for 24 hours.The survival rate of the cells was detected by Cell Counting Kit-8 (CCK-8) assay.Cell morphology as well as the expression and distribution of FAK in the cells were observed by immunofluorescent staining under the laser confocal microscope.Apoptosis was observed by hoechst33258 staining,and Western blot assay was used to quantitatively detect the expression and phosphorylation of FAK.Results The survival rate of the cells was (1.00±0.03) ％,(1.24±0.03)％,(1.36±0.24) ％,(0.93±0.02)％,(1.75±0.19)％,(1.37±0.18) ％,(0.64±0.01)％,(0.59±0.11)％,(0.14±0.05)％ in 0,30,50,70,100,300,500,700,1000 μmol/L H2O2 groups,with a significant difference among them (F =95.30,P =0.00).The survival rates of the cells in the below 300 μmol/L H2O2 groups were significantly higher than those in the 0 μmol/L H2O2 group,and survival rates of the cells in the above 500 μmol/L H2O2 groups were significantly lower than those in the 0 μmol/L H2O2 group(all at P＜0.05).After H2 O2 treatment for 24 hours,HLECs-B3 cells transformed from polygon shape to spindle shape and extended pseudopodiums,meanwhile the green fluorescence for FAK exhibited in the cytoplasm.Cell apoptosis was found in the 1000 μ mol/L H2O2 group.Western blot assay revealed that the expressing levels (grey scale) were significantly different among the various groups (F=28.08,P=0.00),and FAK expressing levels in the below 300 μmol/L H2O2 groups were significantly higher than those of the 0 μmol/L H2O2 group; while the expressing levels in the above 500 μmol/L H2O2 groups were lower than those of the control 0 μmol/L H202 group (all at P＜0.05).After treated by different concentrations of H2O2,the phosphorylation level of intracellular FAK (p-FAK) was significantly higher in 3 hours group than that in 30 minutes group (all at P＜0.05).Conclusions H2 O2 can affect the survival,proliferation and morphology of human LECs by activating the intracellular FAK pathway,indicating that FAK may play roles in the regulation process of cell biological behavior.

Objective To summarize the clinical experience of one stage hybrid operation for aortic arch replacement and explore the indication. Methods From July,2009 to March,2010, 22 consecutive patients received one stage hybrid operation in our hybrid suite for aortic dissection or aortic aneurysm involving aortic arch. Two operative methods are used. (1)Bypass from ascending aorta to brachiocephalic arteries using midstemotomy and normothermia with antegrade aortic arch endovascular stented graft implantation. (2) Ascending aorta replacement and/or aortic valve replacement and/or coronary artery bypass grafting using midstemotomy and cardiopulmonary bypass with antegrade aortic arch endovascular stented graft implantation. Results All patients were technically successful. Angiography during the operation showed 100% patency of all the bypass grafts and no obvious translocation or endoleak of the stents. One patient in the first group died on sixth day after operation due to distal dissection rupture. There was one case of mediastinal lymph effusion in the second group and one case of death due to renal failure and respiratory failure 12 days after operation in the second group. The ICU stay and hospital stay were obviously shorter in hybrid open chest group than that in traditional open chest operation group(P ＜0.05). The blood product consumption and expenditure were also obviously less in hybrid open chest group than that in traditional open chest operation group (P ＜0.05). All the patients were followed up with a mean period of (14.45 ±2.33) months (range: 12 -20 months). All other patients were recovered with normal social life. CT showed neither endoleak nor translocation of the stented grafts. Faulse lumen closure rate at stented-graft segment is 100%. There was no obvious change of distal part of the dissection three months after operation except some thrombosis formation in some of the false lumen. Conclusion One stage hybrid operation for aortic arch replacement is safe and effective in shortening the duration of the operation and reducing the surgical trauma and risk of interval between procedures, shortening the hospital stay and reducing the blood product consumption compared with conventional operation with satisfactory early results. The midterm and long term results are still needed to be followed up.

Kidney transplantation is the treatment of choice for patients with end-stage renal disease, as it extends survival and increases quality of life in these patients. However, chronic allograft injury continues to be a major problem, and leads to eventual graft loss. Early detection of allograft injury is essential for guiding appropriate intervention to delay or prevent irreversible damage. Several advanced MRI techniques can offer some important information regarding functional changes such as perfusion, diffusion, structural complexity, as well as oxygenation and fibrosis. This review highlights the potential of multiparametric MRI for noninvasive and comprehensive assessment of renal allograft injury.

OBJECTIVETo investigate the effects of different concentrations of Gubishu containing serum on the proliferation of rabbit articular chondrocytes cultured in vitro.

METHODSArticular chondrocytes were obtained from the cartilage of 1-month rabbit and cultured in vitro. They were randomly divided into 8 groups,blank and Gubishu groups in different concentrations (5%, 10%,15%, 20%), MTT assay method was adopted to observe the influence of Gubishu containing serum with different concentrations to the proliferation of chondrocytes after incubated 1, 3, 5, 7 and 9 days.

RESULTSThe proliferation of chondrocytes was dependent on the concentration in Gubishu groups. At same time point,there was significant value between every groups, 20% concentration was greatest (P<0.05); There was significant differences between 5%, 10% and 20% concentration of the blank groups at same time point (P<0.05), and was not between 15% and 20% concentration at the 1, 3, 5 and 7 days (P>0.05), 20% concentration of the blank group was greatest. 20% concentrations of Gubishu containing serum was significantly greater than 20% concentrations of blank group at the 1, 3, 5 and 7 days (P<0.05).

CONCLUSION20% concentrations of Gubishu containing serum can significantly increase the proliferation of chondrocytes, and bring the logarithmic growth period forward to the 3 day.
