Objective To evaluate the current situation of two-way referral system by qualitative study.Methods The qualitative study was carried out in Department of General Internal Medicine of Peking Union Hospital and 4 clinics under Beijing Gaobeidian Community Health Center from June to December 2009.In-depth interview was conducted on 6 patients,who were referring from community health center to tertiary hospital and 16 general practitioners in the community.The method of thematic framework was used for data analysis.Results Only 1 of the 6 patients,who made the appointment,completed the two-way referral.From the view of the patients,the interrupt of the two-way referral was due to long-time waiting,inconvenient transportation to the hospital,availability of specialists,unsmooth process of referral and unsatisfied doctors.However,the community health service staff thought that difficulties of the two-way referral originated from the system,doctors,patients,and doctor-patient relationship.Sometimes patients distrusted doctors both in hospital and in community; communications between doctors or between doctors and patients were less efficient; patients had multiple choice for their primary care and they may go to any hospital freely bypass community-based referral system; patients had excessive expectation for medicine and doctors; some patients paid less attention to their own health,and so on.For improvement of the two-way referral system,the community health service staff proposed concrete measures in terms of relevant policy,the hospital,community health service,the doctors and patients; they emphasized the importance of upgrading their own communication ability and professional skills for primary care.Conclusions Many factors may influence successful implement of two-way referral,so it is necessary to improve the relevant policy and procedures and to upgrade medical staff in community.

To explore the population composition and the morbidities and treatment of hypertension and diabetes mellitus among the patients at 4 community healthy service stations at Gaobeidian,Chaoyang District of Beijing during the period of February 2009 to October 2010.A cross-sectional survey was conducted by self-reporting questionnaires.Most patients were above 40 years old,had a lower income level and education status and their treatment costs were mainly covered by social health insurance.Their incidences of hypertension and diabetes mellitus were high.Though most of them could recognize and treat their illnesses,the control rate remained non-satisfactory.Targeting incoming patients,community health service stations should take its advantages of managing chronic diseases and enroll more patients from local communities.

A cross-sectional survey on two-way referral using self-report questionnaire was conducted in a sample of 1423 residents living in 4 communities in Caobeidian area, Chaoyang District and 4 communities in Dongcheng District from April to July 2009. Among the residents who responded the questionnaire, 19.7% (88/446) from Gaobeidian and 8.2% ( 80/977 ) from Dongcheng District were referred to hospitals in 2008. And 30.7 % (27/88) in Gaobeidian and 43.8% (35/80) in Dongcheng District referred to hospital based on their own decision rather than doctors' recommendation; 45. 5% (40/ 88) in Gaobeidian and 45. 0% (36/80) in Dongcheng District of referrals were officiary processed by health institutions. The survey also showed that 57.6% and 59.4% of the respondents from the two districts preferred to free referral between community health service centers and hospitals.

The purpose of this study was to investigate the effects of Celecoxib on the proliferation of the FLT3-ITD positive and negative acute myeloid leukemia cells and its mechanism. The proliferation inhibition effect of Celecoxib with different doses on the FLT3-ITD positive cells MV4-11 and the FLT3-ITD negative K562 cells was detected by CCK-8 method, the cell apoptosis was determined by flow cytometry, and the MEK, Mcl-1, pAKT expression was tested by Western blot. The results showed that Celecoxib inhibited the proliferation of both MV4-11 and K562 cells, but the IC50 for MV4-11 was (29.14 ± 2.4) µmol/L, which was significantly lower than that of K562 cells (39.84 ± 1.0) µmol/L (P < 0.05); The induced apoptosis rate of Celecoxib at 20-80 µmol/L on MV4-11 was not observed, but there was apparent influence on K562 at the same concentration. Western blot showed that Celecoxib down-regulated the expression of MEK and Mcl-1 but did not change the expression of pAKT obviously on MV4-11 cells, while the expression of Mcl-1 was reduced a little, but no obvious change were found in the expression of MEK and pAKT on K562 cells. It is concluded that the Celecoxib can inhibit the proliferation of FLT3-ITD positive AML cells distinctly, and the potential mechanism may be related to the inhibition of the MEK/Mcl-1 signaling pathway.
