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.

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.

He has excellent academic attitude and rich academic achievements,a wide rang of knowledge,which is worth learning and passing on to the younger generations.

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.

OBJECTIVEThis study investigates the immune status of T helper (Th) 17 cells in mice with periodontitis.

METHODSSeven-week-old C57BL/6 female mice were randomly divided into the control and periodontitis groups. Each group comprisedfour mice. Experimental periodontitis was induced in mice by oral infection with Porphyromonas gingivalis in the periodontitis group. Phosphate-buffered saline solution was used in the control group. All mice were sacrificed 4 weeks after the last P. gingivalis infection. CD4⁺retinoid-related orphan receptor (ROR) γτ⁺(Th17) cells were analyzed by flow cytometry. The protein expression of Th17 cell-related cytokine interleukin (IL)-17A was detected by enzyme-linked immunosorbentassay (ELISA).

RESULTSFlow cytometry showed that the percentage of CD4⁺RORγτ⁺(Thl7) cells in all CD4⁺ cells and the cell number in gingival tissues, cervical lymph nodes (CLNs), and the peripheral blood obviously increased (P < 0.01) in the periodontitis group. ELISA showed that compared with the control group, the periodontitis group exhibited an obvious increase in the protein expression of IL-17A (P < 0.05).

CONCLUSIONTh17 cell-mediated cell response is enhanced, and the gingival tissues, CLNs, and the peripheral blood are probably the main locations of Thl7 cell-mediated cell response during the development of periodontitis.

In October 2003, a new bacterial disease with symptoms similar to those caused by Xanthomonas axonopodis pv. poinsettiicola was observed on poinsettia leaves at a flower nursery in Zhejiang Province of China. Three Xanthomonas strains were isolated from infected plants and classified as X. axonopodis. They were differentiated from the pathotype strain LMG849 of X. axonopodis pv. poinsettiicola causing bacterial leaf spot of poinsettia by comparison of pathogenicity, substrate utilization and BOX-PCR genomic fingerprints.

Objective To evaluate a serf-designed diagnostic protoeol which can early detect a femoral neck fracture for patients with a femoral shaft fracture. Methods From September 2005 to June 2007, a self-developed protocol was used to detect an ipsilateral femoral neck fracture for all the patients with femoral shaft fracture who had sought treatment in our department. This protocol consisted of anteroposterior plain radiography of internal rotator, intraoperative fluoroscopy of the hip, a fine (2 mm) cut computed to-mographic scan through the femoral neck, postoperative anteroposterior and lateral plain radiography of the hip in the operating room prior to awakening the patient, at the time of follow-up anteroposterior and lateral plain radiography of the hip in the presence of hip pain. The diagnostic effects of the protocol were compared with those of conventional diagnosis used for all the patients with femoral shaft fracture who had sought treatment in our department from September 2003 to August 2005. A chi-square analysis comparing the protocol group (September 2005 to June 2007) and the non-protocol group (September 2003 to August 2005) was used to assess the early and delayed diagnosis rates for an associated ipsilateral femoral neck fracture. Results The earlydiagnosis rate of an associated femoral neck fracture by the protocol was 93.8%, markedly higher than that by conventional method (46.2%), with statistically significant difference (χ2 = 4.069, P =0.044). Conclu-sion In presence of a femoral shaft fracture. this protocol consisting of plain radiography of intemal rotator, intraoperative fluoroscopy of the hip, fine cut computed tomographic scan of the femoral neck, postoperative plain radiography of the hip, and follow-up plain radiography of the hip in the presence of hip pain, may sig-nificantly improve the diagnostic rate of an associated femoral neck fracture.
