Objective By investigating the actualities of career development potential of eight-year program medical students, to explore a direction of training mode innovation aiming to improve career development potential. Methods Eight-year program medical graduates, their tutors, and di-rectors of their clinical department in a university hospital were the subjects of the current study. Questionnaire method was applied to evaluate professional competence including clinical skills, re-search capabilities and integrative ability . Anonymous questionnaires were dispensed to eight-year program medical graduates for self-evaluation. Distinct anonymous questionnaires were dispensed to tutors directors for evaluation. Traditional doctoral graduates (professional degree or academic degree) were set as standard for comparison of specific ability of eight-year program medical students. Results 74 out of 85 (87%) questionnaires for Eight-year program medical graduates were available. 53 out of 63 (84%) questionnaires for tutors were available. 21 out of 26 (81%) questionnaires for directors of clinical departments were available. In clinical capabilities, according to 43 percent (32 persons) of the eight-year MD graduates' self-assessment and the evaluation of 94%(50 persons) mentors and 81%(17 people) department directors, eight-year program medical graduates were regarded as lower-skilled clinicians compared with doctoral graduates with professional degree . Eight-year program medical graduates were also considered with worse research capabilities than doctoral graduates with profes-sional degree by themselves (76%, n=56), their tutors (91%, n=48), and their department directors (86%, n=18). Conclusions The survey shows that to some extent, the current eight-year clinical doctoral graduates lack of career development potential, reflecting the current training mode cannot lead to the given training goals. We suggest that both clinical skills and research capabilities should be enhanced to make sure that eight-year program medical graduates deserve the title of academic physicianorphysician scientists.

Objective To study the relationship between apoptosis regulation and epidermal proliferation in psoriasis. Methods The expression of apoptosis molecule PDCD5 (programmed cell death 5) on psoriatic lesions was observed by direct immunofluorescence. The positive rates and the average of fluorescence intensity of PDCD5 were analyzed quantitatively with FACS and computer CELL Quest software. The expression of PDCD5 mRNA in psoriatic lesions was detected by RT-PCR. Results The expression of PDCD5 protein was obviously lower in psoriatic epidermal cells than that of the normal skin. The positive rate and the average fluorescence intensity of PDCD5 in psoriatic epidermal cells were notably lower than those of the normal skin (P

Objective To explore effect of probiotics on improving the feeding intolerance in very low birth weight infants(VLBWI). Methods Sixty cases of VLBWI were randomly divided into two groups, 30 infants as therapy group,another 30 infants as control group.All infants in two groups were given aggressive intravenous nutrition and enteral feeding with preterm formulars. At the same time, probiotics were administered combined with preterm formulars to infants in therapy group. Milk amount, gastric residual, initial time of enteral feeding, time required for full enteral feeding and body weight on day 21 after birth were all recorded.Results Rate of no gastric residual increased significantly in therapy group compared with that of control group(t=6.24 P

Objective To evaluate the clinical application of perforator flap in extended radical vulvectomy of vulvar carcinoma.Methods Retrospectively,twelve cases of vulva carcinoma were treated by radical extensive excision,and the defects were repaired with perforator flap.Results All the flaps were survived and healed with first intention except one infection.The wound infection patient was treated with change of the dressing and antibiotics.The reconstructed vulvae were plump and elastic.It appeared like the normal vulvae and there was no contraction of the vagina.Conclusions Vulvar reconstruction with the perforator flap after the radical vulvectomy could make the patients recover easily,which produces almost normal appearance and function of the vulvae,reduces the time of wound healing,the patient could get the next therapy more quickly and the quality of life improving.It has wide clinical application value.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

OBJECTIVEA method for determined oxygen permeability (Dk) of finished soft contact lens.

METHODSOxygen permeability(Dk) of 10 group finished soft contact lens was determined by polarographic method, and the values were linearly calibrated using the measured and established Dk values of the specified reference materials.

RESULTSOnly one Dk value fell outside of the requirement of GB 11417.3-2012 tolerance for Dk (± 20%).

CONCLUSIONIt is great practicability when determined the oxygen permeability (Dk) of finished soft contact lens by polarographic method which were linearly calibrated using the measured and established Dk values of the specified equal thickness reference materials without the measured lens customized 4 different thickness.

ObjectiveTo investigate the effect of Glutamine (Gln) on the expression of PCNA in intestinal tissue of neo-natal rats with necrotizing enterocolitis (NEC), and to explore the protective mechanism of Gln in intestinal mucosa.Methods Forty-eight neonatal rats at the age of 48 hours were selected, and divided into 4 groups, control group, Gln group, NEC group, NECGln group. Each group had 12 rats. Control group were fed mice milk substitutes; Gln group were fed mice milk substitutes mixed with Gln; NEC group were fed mice milk substitutes and had cold/ hypoxia exposure twice a day for 3 days; NECGln group were exposed to cold stress, hypoxia and treated with Gln mixed in the milk. The expression of PCNA was detected using immunohistochemical method.Results Compared with control group were and Gln group, the general condition was worse, and the weight was decreased in NEC and NECGln group. The inifltrated inlfammatory cells, congestion, edema, intrinsic layer separation were observed in intestinal mucosa in NEC and NECGln group. The intestinal villus was lost in severe in NEC and NECGln group. The PCNA index was 34.17±5.78, 34.42±5.38, 15.00±1.94, 30.67±3.14 in control, Gln, NEC and NECGln group respectively, with signiifcant difference between each groups (H=24.32,P=0.000). The expression of PCNA in NEC group was lower than that in normal, Gln, and NECGln group (P<0.008). The expression of PCNA had no signiifcant difference among normal, Gln, and NECGln group (P>0.008).Conclusions The expression of PCNA in intestinal mucosa was decreased in NEC rats. Gln supplement could raise the expression of PCNA in intestinal mucosa of NEC rats, and accelerate the speed of intestinal mucosa repair.
