A teaching method called cross-disciplinary joint teaching,which integrated the neural system-based physiology,anatomy and histology from gross morphology to micmstructure,then to physiological function,was carried out on 2010 clinical eight-year program medical students.Jointteaching method was carried out throughout the whole courses.That means in three subjects related to the discipline,teachers compile the textbook,discuss teaching scheme,compile cases,collectively prepare lessons,and attend lectures and discussion together.Flexible teaching forms such as casebased teaching,problem-based teaching and bilingual teaching were also run through the whole processes of the teaching.Compared with the traditional teaching model,cross-disciplinary joint teaching not only achieves the integration of morphology,microstructure and functions of nervous system,but also has a priority of helping the students to develop a more efficient learning ability such as initiative study and thinking extension.

OBJECTIVE:To study the optimal monitoring indexes of plasma concentration of cyclosporine A(CsA) in patients receiving hematopoietic stem cell transplantation.METHODS:The lowest CsA concentration(C0) and the highest CsA concentration(C2) in 23 hematopoietic stem cell transplant recipients were detected by FPIA.All the data were analyzed statistically.RESULTS:Within 6 months after hematopoietic stem cell transplanttion,C0,C2,C0+C2 and C2/C0 in the recipients were(228.84?142.48) ?g?L-1,(741.50?294.42) ?g?L-1,(970.34?391.18) ?g?L-1 and(3.88?1.94) ?g?L-1,respectively.CONCLUSION:As reasonable monitoring indexes for the plasma concentration of CsA,C0+C2 and C2/C0 can comprehensively reflect the exposure of drug in body and monitor the toxicity of CsA in liver and kidney.

OBJECTIVETo explore the effect of dexmedetomidine combined electrical stimulation on cognitive function of neurosurgical diseases patients treated by extracerebral intervention.

METHODSTotally 122 patients with neurosurgical diseases who underwent selective intervention were randomly assigned to the observation group and the control group, 61 cases in each group. Patients in the control group recieved anesthesia by dexmedetomidine. Those in the observation group received electrical stimulation at Baihui (DU20), Yintang ( EX-HN3), and Neiguan (PC6) before dexmedetomidine anesthesia. The cognitive function of patients at preoperative day 1 and postoperative day 1 was respectively evaluated by Mini-Mental State Examinations (MMSE). Serum NSE, S-100β, IL-1β, IL-6, and TNF-α levels were detected in the two groups before intervention and immediately after intervention using ELISA.

RESULTSMMSE scores of two groups were significantly reduced at post-intervention day 1, as compared with one day before intervention. MMSE score of the observation group at post-intervention day 1 was (23.15 ± 1.87) points, significantly higher than that of the control group [ (19.34 ± 1.64) points , (P < 0.05)]. The postoperative cognitive dysfunction (POCD) incidence rate of the observation group was 16.4% (10/61), significantly lower than that of the control group [39.3% (24/61); P < 0.05]. Compared with before intervention, NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels of the two groups increased (P < 0.05). Post-intervention NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels were significantly lower in the observation group than in the control group (P < 0.05).

CONCLUSIONDexmedetomidine combied electrical stimulation could effectively prevent the occurrence of postoperative cognition, and reduce levels of NSA, S-100β, IL-1β, IL-6 and TNF-α.

OBJECTIVETo investigate the expression of long non-coding RNA-HOTAIR in prostate cancer cells and its effects on the growth and metastasis of the cells.

METHODSUsing quantitative reverse-transcription PCR (qRT-PCR), we determined the relative expression of HOTAIR in the normal human prostate epithelial cell line RWPE-I and prostate cancer cell lines PC-3 and DU145. We detected the effects of HOTAIR on the cell cycle and invasiveness of prostate cancer cells by RNA interference, flow cytometry, and Transwell mitration assay.

RESULTSThe expressions of HOTAIR in the PC3 and DU145 cells were increased 3.2 and 5.7 times, respectively, as compared with that in the normal RWPE-1 cells. After si-HOTAIR interference, the prostate cancer cells were arrested in the G2 phase and downregulated in the G1 phase. The invasive ability of the prostate cancer cells was evidently inhibited, with the inhibition rates of 32% and 44% of the PC3 cells and 43% and 34% of the DU145 cells for si-HOTAIR1 and si-HOTAIR2, respectively.

CONCLUSIONIncRNA HOTAIR is highly expressed in prostate cancer, which is associated with the growth and invasiveness of prostate cancer cells. HOTAIR is potentially a novel marker for the diagnosis and prognosis of prostate cancer.

Objective To understand the correlations between HIV-1 subtypes and changes in CD4+T cell count over time in patients with different subtypes of HIV-1 infection.Methods A total of 94 patients who were diagnosed with HIV-1 infection in Nanjing and received at least twice CD4+T cell counting test before antiretroviral therapy (ART) were recruited in this study.Descriptive analysis was used to present the rates of CD4+T cell decline for different HIV-1 subtypes.Logistic regression analysis and nonparametric test were conducted to investigate the factors responsible for CD4+T cell decline and to analyze the correlations between the rates of CD4+T cell decline and HIV-1 subtypes.Results The median monthly rate of CD4+T cell decline was-2.20 [interquartile range (IQR):-11.36-2.13] cell/μl.Of all patients,25.5% (24/94) had a significant decline (≥30%) in CD4+T cell count.Compared with the patients infected with CRF01_AE,those infected with CRF07_BC (OR=0.28,95%CI: 1.7-6.5) or other subtypes (OR=0.16,95%CI: 1.0-2.9) had a lower risk of significant decline in CD4+T cell count.In addition,results of the nonparametric test showed that the patients infected with CRF01_AE (M=-21.54,IQR:-30.97——11.92 cell/μl) had a faster CD4+T cell loss than those infected with CRF07_BC (M=-11.26,IQR:-14.06——5.63 cell/μl) (P=0.033).Conclusion HIV-1 subtype is associated with the rate of CD4+T cell decline.It is important to monitor the changes in CD4+T cell count in patients infected with CRF01_AE and to carry out timely ART.

It is a trend that innovate the traditional bilingual education model and select a new teaching model.Code-switching is a lingual phenomenon when a passages or articles are expressed with two or more language.To guarantee effect of bilingual education and improve education quality,penetration bilingual education was applied during microbiology teaching.Professional English vocabulary,words,passages or articles were introduced to students timely and by measure by the way of language code-switching.The results showed that bilingual teaching mode with language code-switching inspire study emotion and self-confidence of English expression from students.

Objective To compare the effect of atorvastatin and rosuvastatin on myocardial injure and inflammatory factors in patients with unstable angina pectoris(UAP)undergoing percutaneous coronary intervention(PCI).Methods Ninety six UAP pa-tients undergoing PCI were enrolled in the study and divided into two groups,patients were given atorvastatin(20 mg/d)or rosuv-astatin(20 mg/d)besides conventional treatment for 1 week before PCI.Datas were collected before medication,PCI and Twenty-four hours after PCI,including CK-MB,cTnI,hs-CRP,TNF-α,IL-6 and IL-10.Results Twenty-four hours after surgery,the PCI, CK-MB,cTnI,hs-CRP,TNF-α,IL-6 of rosuvastatin group were lower than those of atorvastatin group(P <0.05),but IL-10 of ro-suvastatin group was higher than that of atorvastatin group(P <0.05).Conclusion Rosuvastatin (20 mg/d)is better than atorvas-tatin (20 mg/d)in the efficacy of UAP patients undergoing PCI,which can reduce the level of myocardial injure and inflammatory factors effectively.

ObjectiveTo investigate the effects of different amounts of iodine intake on the cellular and humoral immune in Grave's disease (GD) patients.MethodsThe clinical GD cases were diagnosed by thyroid fine needle Cytology examination.Patients in GD group are divided into GD group Ⅰ and GD group Ⅱ based on the median of urine iodine.The blood levels of FT4,FT3,TSH,TPOAb,TGAb,TRAb and TNF-t were detected.The difference and association of these parameters between these groups were analyzed.ResultsThe TNF-αt level in GD Ⅰ group was higher than that of GD Ⅱ group( P ＞ 0.05 ) ;The average level of TRAb of GD Ⅰgroup ( [ 1.4 ±0.2 ] U/L) were higher than that of GD Ⅱ group ( [ 1.2 ± 0.1 ] U/L) ( P ＜ 0.05 ) ;The positive rates of TGAb and TPOAb of GD Ⅰ group were higher than that of GD Ⅱ group ( P ＜ 0.05 ).The percentages of patients with high level of TGAb and TPOAb in GD Ⅰ group ( 78.9％ 、84.2％ ) were higher than that in GD Ⅱ group (50.0％,62.5％ ) ( x2 =6.79,10.70,P ＜0.05 ) ; Analysis showed a linear positive correlation of TNF-αwith TRAb and TPOAb ( r is 0.489 and 0.563,P ＜ 0.01 ).ConclusionIodine is an important factor to the development of Graves disease.Excessive iodine intake will exaggerate the GD condition and patients with GD should be controlled for iodine intake.
