Professional development of faculty is an essential component of strategy for medical schools to construct teaching team.Development of education is dependent upon the professional quality of teaching staff.Starting from connotation of faculty's professionalism,this paper compared present status of composition of teaching staff in China with that in foreign countries,explored the potential approaches for medical schools to strengthen the construction and sustainable development of teaching staff.

Objective To establish transplantable rat prostate carcinoma and study its relationship to hormone dependency. Methods Six transplantable rat prostate carcinoma lines were established from primary tumors developing in the dorsolateral prostate of F344 rats receiving a combined treatment with 3, 2’-dimethyl-4-aminobiphenyl (DMAB) and testosterone propionate (TP). Results Growth in the subcutis of nude mice (ICR-nu/nu) is rapid with a doubling time of approximately 10 days and transplantability is 100%. The histological appearance of the transplanted tumors is very similar to that of the primaries and their structures have not been altered by after 8 passages. Androgen receptor immunohistochemistry revealed all to be negative. Conclusions These data indicate that the model should prove useful for studies of invasion, metastasis, and hormone dependency of prostate carcinomas.

Objective To observe the therapeutic efficacy of acupuncture plus hyperbaric oxygen in treating post-stroke depression. Method Sixty patients with post-stroke depression were randomized into a treatment group of 30 cases and a control group of 30 cases. The treatment group was intervened by acupuncture plus hyperbaric oxygen, while the control group was by Fluoxetine. Before and after intervention, the Hamilton Depression scale (HAMD) was adopted for evaluation, and the efficacies were compared. Result The total effective rate of the treatment group was significantly higher than that of the control (P<0.01);after intervention, the HAMD score of the treatment group was markedly lower than that of the control (P<0.01). Conclusion Acupuncture plus hyperbaric oxygen can obviously improve the depression symptom and promote the recovery of neurologic function in patients with post-stroke depression.

Objective To study the mechanisms underlying this loss of AR expression in rat prostate cancer. Methods The methylation status of the AR gene promoter region in rat prostate cancer and cell lines (PLS10,20,and 30) was investigated by Southern blotting,methylation-specific polymerase chain reaction,and methylation-sensitive single-strand conformation analysis (MS-SSQA). Results AR mRNA expression was not detected in any of the rat prostate cancers or cancer cell lines tested by Northern blot analysis. Higher levels of methylated CpGs were observed in PLS20 than that in PLS10 or 30. Demethylation treatment by 5-aza-2’-deoxycytidine restored AR mRNA expression in PLS20.The CpGs was suggested to be responsible for AR expression in rat prostate cancer,and found to be located-9 and-1 nucleotides upstream of the transcriptional initiation site.All of the examined rat prostate and seminal vesicle cancers demonstrated hypermethylation at these CpG sites. Conclusions These data clearly demonstrate that aberrant hypermethylation in the AR promoter region may play a critical role in AR expression in rat prostate cancers.Loss of AR expression might result in development of hormone-resistant prostate carcinoma.

Objective To investigate antibiotic resistance of Neisseria gonorrhoeae strains isolated from female patients. Methods:Antimicrobial susceptibility of N.gonorrhoeae to 7 antibiotics was tested by disk diffusion method and penicillinase- producing N.gonorrhea(PPNG)was confirmed by nitrocefin disk.Results:Of the 95 strains collected,38(40%)were found to be PPNG.No resistance to spectinomycin was identified.The susceptibility rate of these isolates to penicillin,tetracycline, and ciprofloxacin were much lower,only from 0% to 2.6%.More than 90% of the isolates were susceptible to cefuroxime, ceftriaxone,and ceftizoxime.Conclusions:Our study suggests that spectinomycin,cefuroxime,ceftriaxone,ceftizoxime are the first choice for treatment of gonorrhea in female patients.

Objective To explore the optimal process conditions for cold-soaking extraction of fat-soluble components in Radix Salviae Miltiorrhizae.Methods Tanshione Ⅱwas determined by HPLC.The effect of different concentrations of ethanol and comminution on the extraction rate of tanshione Ⅱwas observed,and the process conditions were optimized by orthogonal test.Results The optimal process conditions for obtaining higher extraction rate of tanshione Ⅱwere as follows: the medicinal material was extracted by cold-soak extraction with 95% ethanol for two times(3 hours for each time),and the volume of ethanol was as much as 8 times of the medicinal material.Conclusion The extraction process is simple,stable and efficient for Radix Salviae Miltiorrhizae.

[Objective] To observe the regulatory effect of Huangqi Injection (HI) on immune function of patients after chemotherapy (CT). [Methods] Thirty-four patients confirmed as acute myelogenous leukemia (AML) received two cycles of CT. During the 1st cycle, the patients were only treated with DA (daunomycin + arabinoside) regimen; in the 2nd cycle, intravenous injection of 20 mL of HI, qd for 2 weeks was added. The effect of CT on myelosuppression and immune function of the patients was observed. [Results] Immunosuppressive manifestations such as myelosuppression, fatigue, spontaneous sweating, impaired appetite, lassitude were found after the 1st cycle of CT, and peripheral immunoglobulin A (IgA), IgG, IgM and complements C3 levels were also decreased (P

Objective To investigate the physiological responses of healthy youth to doing chest compression as a feedback of quality of CPR after their rapid ascent to high altitude and to evaluate the feedback in the intervention effects of CPR.Methods Prospective,single sample,before-after comparison method was used in this study.Fifteen young adults from plains natives were enrolled as trial subjects in this study.All of them received basic life support training course in advance.In Chongqing (259 m above sea level),subjects performed empiric chest compressions on the model body for 4 minutes followed by feedback compressions for 4 minutes after at least 30 minutes rest.Compression depth,rate and other compression quality parameters were measured and recorded at each turn of compressions with an AED PLUS device.Subjects performed empiric compressions based on their knowledge and experiences,and practiced feedback compressions according to the audiovisual guidance of AED PLUS device.Blood pressure,heart rate and SpO2 were taken before and after each turn of compressions.One week after arrival to Lhasa (3658 m above sea level) by flight,all subjects were asked to do the same procedure as did in Chongqing to see their physiological response to.Paired t tests or Wilcoxon matched pair rank test were used for comparisons of measurements before and after trials.Results Systolic pressures,diastolic pressures,heart rates at baseline in Lhasa were significant different from those in Chongqing,including systolic pressure (125.9 ±9.5) mmHg vs.(112.7 ±13.4) mmHg,diastolic pressure (75.3 ±7.7) mmHg vs.(64.2 ±7.3) mmHg,heart rate (86.3 ± 13.0) beat/min vs.(72.7 ± 11.6) beat/min,SpO2 (90.4 ± 1.7)％ vs.(97.8 ±0.9)％,all P ＜ 0.01.In Lhasa,empiric compressions only caused an increase in heart rate (91.1 ± 14.9) beat/min vs.(86.3 ± 13.0) beat/min,P ＜ 0.01.However,feedback compressions resulted in a significant decrease in SpO2 [(88.3 ± 3.4) ％ vs.(90.6 ± 1.9) ％,P ＜ 0.01] as well as change of systolic pressure [(130.9 ± 11.7) mmHg vs.(120.1 ± 11.9) mmHg,P ＜0.05] and heart rate [(87.9 ± 17.5) beat/min vs.(80.9 ± 11.7) beat/min,P ＜0.05].In Lhasa,the compression quality during feedback compressions was closer to guideline recommendation than that during empiric compressions.The median (interquartile range) of composite qualification rate was 43.6％ (55.9％) vs.0.6％ (5.3％) during feedback compressions and empiric compressions respectively,P ＜ 0.01.Conclusions Compression quality decreased significantly among youth after rapid ascent to high altitude.Feedback techniques for CPR could effectively guide the rescuer to improve their CPR quality,but it may be at the expense of more physical consumption.
