Insisting on public-interest nature of health is the basic principle of new-round health reforms and development in China. The evaluation of its magnitude is an important means to carry out public-interest develop-ment. This paper clarifies the meaning of the public-interest nature of health and its magnitude and other related con-cepts and discusses why the health system has the attribute of public-interest, points out related systematic arrange-ments that should be designed to ensure the direction of public-interest in health reform. The paper also suggests that a system of measuring the realized magnitude of this nature in health reform be established to evaluate the performance and provide reference for evidence-based policies.

Objective To explore the effect of stance width on balance in static standing.Methods Thirty healthy young subjects were evaluated using the PRO-KIN balance training apparatus.They stood with their eyes open and closed in three stances:feet together,feet 50 cm apart,and feet a comfortable distance apart (measured as 18.63±3.67 cm between the heels and 29.60±4.93 cm between the toes).The excursions of the center of pressure (COP),the standard deviation of their longitudinal sway (SDLS),the standard deviation of their horizontal sway (SDHS),the mean longitudinal and horizontal sway velocities (MVLS and MVHS),sway length (SL) and sway area (SA) were recorded.Results With the eyes either open or closed,significant differences in all of the COP data were observed when standing in the different stances.The average SDHS,MVHS,SL and SA were all significantly better when standing comfortably than when standing with the feet 50cm apart whether the eyes were open or closed.Conclusion There is a proper distance between the feet where healthy youngsters best maintain static standing balance.

At present, selective 5-hydroxytryptamine (5-HT) reuptake inhibitors (SSRIs) and 5-HT and noradrenaline (NA) re-uptake inhibitors ( SNaRI) are the first choice for the clinical treatment of depression, however, the clinical adverse effects of the drugs have become a prominent problem affecting the clinical efficacy. Chinese medicines have some experience in the treatment of depres-sion, and the combined use with the above antidepressants can enhance the efficacy and / or reduce the adverse effects. The article re-viewed the status of the combination of SSRIs and Chinese medicines in order to provide reference for the clinical treatment of depres-sion.

Costimulatory signals have become a hot field in immunological researches. As co-inhibitory molecules, programmed death-1 ( PD-1) and its ligands (PD-1/PD-L) have been demonstrated to play an important role in autoimmune disease, organ transplant rejection, microorganism infection, tumor immune escapes etc. . In recent years,some studies about PD-1/PD-L pathway in ophthalmology have been curried out and reported. Some changes were found in PD-1/PD-L pathway, such as ocular immunologic diseases, ocular infectious diseases, ocular tumors, immune privilege in ocular tissues and so on. Through the research on PD-1/PD-L pathway,we can further understand the pathogenesis of some ocular diseases and find new methods for their prevention and treatments. This article reviewed the recent advances in PD-1/PD-L pathway in ophthalmological physiopathology.

Objective To investigate the clinical characteristics and currently treatment status of intractable ulcerative colitis (IUC). Methods A retrospective analysis was conducted on the data of inflammatory bowel disease patients, who were hospitalized in Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University, from January 1999 to December 2009. According to the reaction to glucosteroids (GCS) treatment, they were divided into GCS effective group and intractable group. The general data, lesion, clinical symptoms and laboratory findings of these two groups were compared.Further treatments and the results of intractable group were analyzed. Results Totally 234 UC patients were enrolled, of which 37.6％ (88/234) patients received GCS treatment, intractable group and effective group took up 23.9％ (21/88) and 76.1％ (67/88) respectively. There was no significant difference of lesion between two groups (P＞0.05). Compared with effective group, the proportion of intractable group was higher in moderately severe bellyache[38. 1 ％ (8/21) vs 13. 4％ (9/67), P＝0.012, OR＝3.97, 95％CI:1.29～12.23], anemia[61.9％(13/21) vs 32.8％(22/67), P＝0.018,OR＝3.32, 95％CI:1.20～9.20], thrombocytosis[57.1％(12/21) vs 29.9％(20/67), P＝0.023,OR＝3.13, 95％ CI: 1.14 ～8.61]and hypoalbuminemia[38.1 ％ (8/21) vs 11.9％ (8/67), P＝0.007, OR＝4.54, 95％CI: 1.44～ 14.32]. Some patients of intractable group could be remission through extending period of GCS treatment, adding the immunomodulators or biological agents and intestinal segment excision. Conclusion UC patients with moderately severe bellyache, anemia,thrombocytosis, hypoalbuminemia at the onset of disease, which may indicate relatively poor response to GCS treatment. Immunomodulators, biological agents and surgery are the further treatment for IUC patients.

Objective To identify and evaluate the important risk factors for preeclampsia.Methods Databases of PubMed,Web of Science,Ovid CBM,China Knowledge Resource Integrated Database,Wanfang and VIP Database were searched from January 1,1990 to December 31,2012 to collect the cohort and case control studies involving the risk factors for preeclampsia.According to the inclusion and exclusion criteria,data of the included studies were extracted.Meta-analysis was performed using Stata 12.0 software with DerSimonian Laird model to calculate OR and its 95％CI of each risk factor.Results A total of 20 studies involving 53 393 patients in the research group and 1 197 773 cases in the control group were included.Fifteen risk factors for preeclampsia were investigated,including:history of preeclampsia (OR=10.27,95％CI:7.67-13.75),complication with chronic kidney diseases(OR=4.69,95％CI:1.94-11.33),history of chronic hypertension (OR-3.47,95％CI:2.39 5.04),multiple pregnancy (OR-2.98,95％CI:2.43-3.66),pre pregnancy body mass index (BMI) ≥ 25(OR=2.47,95％CI:1.97 3.09),maternal hyperglycemia(gestational diabetes and pre existing diabetes)(OR=2.84,95％CI:2.28-3.55),primiparity (OR=2.47,95％CI:2.12-2.82),physical work during pregnancy (OR=1.62,95％CI:1.30-2.02) ; family history of hypertension (OR=2.14,95％CI:1.84-2.50),basic diastolic blood pressure ≥ 70 mmHg (OR=2.17,95％CI:1.44-3.27),low education levels less than junior school (OR=1.69,95％CI:1.34 2.15),basic systolic blood pressure ≥ 120 mmHg (OR=2.31,95％CI:1.86-2.86),urinary tract infection (OR=1.96,95％CI:1.54-2.48),maternal age ≥ 35 or ≤ 20 years (OR=1.43,95％CI:1.29 1.57) and mental ademosyne (OR=1.35,95％CI:1.24-1.47).In addition,smoking before or during pregnancy was found to decrease the incidence of preeclampsia (OR-0.66,95％CI:0.56 0.79).Conclusions The main risk factors for preeclampsia are:history ofpreeclampsia,complication with chronic kidney diseases,history of chronic hypertension,multiple pregnancy,pre-pregnancy BMI ≥ 25,maternal hyperglycemia,primiparity,work during pregnancy and family history of hypertension.Smoking may decrease the incidence of preeclampsia.Nevertheless,more emphasis should be laid the adverse perinatal outcomes of smoking.
