There are problems in traditional medical education in China. It is important to cultivate medical talents who are adaptable to social changes and medical advancement. However, the scientific quality and innovative medical students have long been neglected. This paper discussed the essence of scientific quality and innovative talents, and introduced the experience of the program of "long term clinical medicine education" at Peking University Health Science Center. We here delineateded the key points of the scientific quality and innovation education that may provide new ideas for the training of the medical talents.

Objective A quick and sensitive method was developed for determination of folic acid (FA) in infant formula milk powder. Method Perchloric aicd was added into infant formula milk powder to extract FA in ultrasonic wave condition. After solid-phase extraction (SPE) with C18 material as plug and reaction with potassium permanganate, FA was determined by reversed phase high-performance liquid chromatography (RP-HPLC). pH 5.0 and 0.1 mol/L sodium dihydrogen phosphate were used as mobile phase. the flow rate was 1 ml/min. BDS C18 was used as separating column and column temperature was 30 ℃. Results The linear range of the method was 0.005-1.5 ?g/ml. The average recovery was 91.7%- 98.3%. The relative standard deviation (RSD) was 2.5%. The limit of detection was 0.005 ?g/ml, and the limit of quantification was 0.017 ?g/ml. Conclusion The method has following advantages: simple, precise, accurate and easy to practice.

A total of 40 patients with COPD (excluding those with correlated/relevant diseases)were measured for inflammation parameters of erythrocyte sedimentation rate (ESR) and c-reactive protein (CRP) after hospital admission and some coagulation/fibrinolysis parameters including D-dimer,thrombinantithrombin (TAT),prothrombin fragment 1 + 2,(tissue plasminogen activator) tPA,plasminogen activator inhibitor 1 (PAI-1),von Willebrand factor (von WF),endothelin receptor A,thromboxane B2,P-selectin and pulmonary arterial pressure (PAP) by ultrasonic cardiography after the settling of the symptons of acute period.All patients were then divided into 2 groups according to PAP [< 40 mm Hg (1 mmHg=0.133 kPa) (n=24),>40 mm Hg (n=16)].The values of CRP and ESRin the group with PAP > 40 mm Hg were significantly higher than those in another group (P =0.044 and P =0.002respectively) while tPA was lower (P =0.04).A moderate positive correlation existed between tPA and TXB2 (r =0.547).Moreover,a highly positive correlation was found between TXB2 and PAl-1 (r =0.929).The results indicated that the COPD patients with pulmonary arterial hypertension (PAH) tend to have a higher level of inflammation,and their fibrinolysis becomes impaired leading to a prothrombotic state.

ObjectiveTo explore the epidemiologic feature of maternal syphilis and the status of prevention and control of the disease in Baoshan District. Methods Syphilis monitoring data of pregnant women were analyzed retrospectively in Baoshan district of Shanghai from 2004 to 2009. Results The positive rate of syphilis in pregnant women was 0.31% ( 195/63 227 ).Among them,residing and migratory pregnant women accounted for 0.17% (37/22 287) and 0.39% (158/40 940) respectively (X2 =22.699,P <0.01 ). A total of 145 cases received the examination of treponema pallidum particle agglutination (TPPA).And 136 cases were positive.The positive rate of rapid plasma reagin test (RPR) was 51.35%(19/37) in residing early pregnant women and 24.68% (39/158) in migratory counterparts (X2 =22.192,P =0.000).And 152 cases were followed up to record pregnancy outcomes,including normal delivery of live births ( n =146 ),artificial termination of pregnancy ( n =3 ),stillbirth and spontaneous abortion ( n =3). Forty-three cases became lost. And the rate of loss was 22.78%(36/158) in migratory pregnant women and 18.92%(7/37) in residing counterparts. Conclusions It is imperative to improve the prevention and control mechanisms of pregnancy syphilis and the model of consulting services. We should also pay more attention to screening and follow-up work in migratory pregnant women.

ObjectiveTo investigate the effects of acupuncture on neuromuscular block of vecuronium and analgesia under general anesthesia.MethodsNinety ASA Ⅰ or Ⅱ patients,aged 29-80 yr,weighing 50-80kg,scheduled for laparoscopic chotecystectomy,were randomly divided into 3 groups (n =30 each):acupuncture at acupoints combined with general anesthesia group (group A),acupuncture at non-acupoints combined with general anesthesia group (group B) and general anesthesia group (group C).Bilateral Hegu (LI4),Neiguan (PC6),Zusanli (ST36),yanglingquan (GB34),and Quchi (LI11) acupoints were selected in group A.In group B,the points adopted were the midpoints between the meridians in which the acupoints were selected in group A and the adjacent meridians on the lateral side,at the level of selected meridian points correspondingly.Electric stimulation was started from 15-30 min before anesthesia induction and continued until the end of operation.Anesthesia was induced with iv injection of fentanyl,propofol and vecuronium and maintained with intermittent iv boluses of fentanyl and vecuronium.All the patients received patient-controlled intravenous analgesia after operation.The effect time,onset time,clinical duration and recovery index of vecuronium,consumption of anesthetics during operation,and consumption of fentanyl for postoperative analgesia and postoperative adverse reactions were recorded.Results Compared with group C,the elinical duration was significantly prolonged,the consumption of anesthetics during operation and consumption of fentanyl for postoperative analgesia were significantly reduced,and the incidence of nausea was significantly decreased ( P < 0.05 ),while no significant changed was found in the effect time,onset time,and recovery index in group A ( P > 0.05).Compared with group B,the amount of fentanyl consumed during and after operation was significantly reduced in group A ( P < 0.05 ).ConclusionAcupuncture can prolong the clinical duration of vecuronium,and enhance the analgesic efficacy during and after operation under general anesthesia.

Objective We analysed the homocysteine level and distribution of ganzhou city crowd ,learned about its elevatory sit‐uation ,and provided theory basis for the intervention of high homocysteine level crowd and the prevention of heart and head blood vessel disease .Methods We detected the blood homocysteine level of 6419 adults who had physical examination in our hospital dur‐ing 2012 by enzymatic methods ,and analyzed the diagnose rate of HHcy and the distributions of Hcy in different age and gender . Results The total detection rate of high homocysteine level in 6419 adults was 39 .11% ,among which 47 .30% in male and 22 .49% in female ,the comparison was statistically significant (χ2 = 424 .28 ,P< 0 .05) ;the detection rate of male was higher than female .In different ages ,the detection rates were statistically significant comparatively (P< 0 .05) .The detection rate of homocys‐teine level in both gender rises with age .At the same time ,homocysteine levels in males of 25 - 34 years old age group and 35 - 44 years old age group ,45 - 54 years old age group and 55 - 64 yeas old age group were not statistically significant ;while there were statistical differences of Hcy level in the rest age groups of male ,different age groups of female and same age different gender groups (P< 0 .05) .Conclusion The HHcy detection rate and the blood Hcy distribution of Ganzhou city crowd has its regional characteristics compared with other regions ,and it may be associated with the main population distribution of hakka people and oth‐er geological factors .The detection rate of HHcy was relatively high ,and it′s advisable to take early prevention to lower the risk of heart and head blood vessel disease .
