Both of "Medical Microbiology"and "Medical Immunology"are two important basic and required medical courses for college students.There is something worth discussing in some respects,including the composing of teaching materials,designing of curriculum,key points of teaching and practical application.It's necessary to deal with the relationships well between the teaching effects and the issues such as arrangements of class period,selection of teaching material and the design of teaching.Particularly,we should emphasize close connection between the basic and clinical course.

Objective To evaluate the curative difference of laparoscopic cholecystectomy (LC)between elder and middle age.Methods Patients with gallbladder disease who underwent LC from 2006 to 2011 were collected and divided into elder group (≥65 years old,35 patients) and middle age group(＜ 65years old,353 patients).The operation time,conversion rate,postoperative complications,time to first oral intake,time to first ambulation and hospitalization time were compared.These patients were divided into simple gallbladder disease group (included recurrent biliary colic,chronic cholecystitis,gallbladder polyps)and the complex gallbladder disease group (included acute cholecystitis,gallbladder empyema,acute cholecystitis perforation).The age,WBC,operation time,postoperative complicantions and hospitalization time were evaluated.Results The operation time,conversion,postoperative complications rate,time to first oral intake,time to first ambulation and hospitalization time had no significant difference between elder group and middle age group (P ＞ 0.05).The age,conversion rate between simple gallbladder disease group and complex gallbladder disease group had no significant difference (P ＞ 0.05).But the WBC,operatian time,postoperative complications,hospitalization time in simple gallbladder disease group had significant difference compared with complex gallbladder disease group [(7.32 ± 2.12) × 109/L vs.(11.35 ± 4.62) × 109/L,(62.3 ±29.5) min vs.(79.5 ±49.2) min,3.1％(10/322) vs.9.8％(5/51),(5.0 ±3.7) d vs.(7.9 ± 6.5) d,P ＜ 0.01 or ＜ 0.05].Conclusions Age is not the risk factor of LC in elderly patients,but the disease type has a significant effect on the choice of LC.

Objective To quantitatively assess the neovascularization within human carotid atheroclerltic soft plaque in patients with cerebral infarction using real-time contrast-enhanced uhrasonography. Methods One hundred and forty-two patients with carotid athemselerotic soft plaque were divided into two groups: cerebral infarction group (n = 44)and control group (n = 98).Real-time contrast-enhanced ultrasonography was examined. Acoustics quantitative analysis was made by auto-tracking contrast quantification (ACQ)technology. Results The enhanced intensity (EI)in cerebral infarction group was significandy higher than that in control group[(14.58±4.19)dB vs (11.26±3.77)dB, P< 0.01]. The difference of arrival time (DAT)and the difference of time to peak (DTrP)in cerebral infarction group was significantly shorter than those in control group [(2.21±0.42)s vs (2.46±0.51)s,(2.13 + 0.37)s vs (2.43±0.48)s, P all < 0.01]. Conclusions The real-time contrast-enhanced uhrasonography can provide a new non-invasire and quantitative tool to assess the neovascularizafion within carotid atheroselerofic soft plaque. EI is re-garded as an independent risk factor correhtes strongly with cerebral infarction.

BACKGROUND: With development of modern medical sciences, the out comes after meningioma surgery cannot be fully assessed using morbidity,livability and mortality merely. Quality of life (QOL) is a health-related multivariable index, which provides integrated inf ormation associated with physiological,sychological and social adaptation status of the patients to doctors. Assessment of the QOL in meningioma patients may be one of a relatively good method for guiding surgery and reducing reoccurrence of tuOBJECTIVE: To evaluate the QOL in meningioma patients and then to provide relevant data for assessing the outcomes of meningioma surgery comprehensively.DESIGN: It was a single-sample investigation. SETTING: Neurosurgery Department, Second People's Hospital of Wuxi City of Nanjing Medical University.PARTICIPANTS: Totally 147 patients underwent meningioma surgery in the Neurosurgery Department of the Second Affiliated Hospital of Wuxi City affiliated to Nanjing Medical University between January 1995 to January 2001 were selected, 61 males and 86 females, with a male/female ratio of 2:3 and an age ranging from 5-77 years old, in average of 43 years old, and the median was 43 years old.METHODS: Based on World Health Organization Quality of Life 100item questionnaire (WHOQOL-100) and Karnofsky Performance Scale (KPS), we designed a questionnaire on QOL in patients with meningioma.Outcomes of the transverse investigation on 147 meningioma patients were compared with healthy controls. Surgery-related QOL curve was used for identifying the threshold satisfactory point of QOL. In addition, with selfcontrol, influence of surgery on QOL was assessed.MAIN OUTCOME MEASURES: Relationship between QOL and clinical histories, radiological analysis, operation grading, histological properties and reoccurrence were investigated.RESULTS: All of the 147 patients entered the statistical analysis. ①In patient with meningioma, Cronbach's coefficient was 0.9521 and the correlated coefficient was 0.8685, which suggested that QOL questionnaire for patients with meningioma had a good reliability and validity. ②QOL ≥70 represented that the patient was satisfied with the QOL. ③In patients underwent surgical treatment, their physiological functions, self-help and self-care except for psychological functions were significantly improved (P ＜ 0.001 ).CONCLUSION: Surgical treatment enables patients to get a satisfied QOL. QOL questionnaire for patients with meningioma is helpful to provide relevant data for meningioma operation.

Objective To discuss the effects and mechanisms of tetramethylpyrazine(TMP)on learning and memory abilities of Alzheimer's disease(AD)mice.Methods The animal models of AD were induced by aluminium trichloride(AlCl3)intragasticly for forty days.Then,TMP was intragastricly administered for twenty days.The escape latency of the mice in water maze test was recorded;and AChE and SOD activities and MDA levels in the brain were detected by chemical eoiorimetrie method.The expressions of At3 and NF-κB in the cerebral cortex were measured by immunohistochemistry method.Results 1)TMP has markedly decreased escape latency in AlCl3 induced AD mice(P＜0.05).2)In the brain of AlCl3 induced AD mice,TMP reduced AChE activity 19%[(1.37±0.13)U·mgpro-1vs(1.69±0.27)U·mgprot-1,P=0.016],decreased MDA levels 34% [(43.63 4-13.27)nmol·mgprot-1 vs(28.59±8.52)nmol·mgprot-1,P=0.023]and increased SODD activity 39%[(55.81±10.25)U·mgprot-1 vs(40.04±13.06)U·mgprot-1,P=0.026],respectively.These resuits showed significant difference with model mice group(P＜0.05).3)TMP also decreased AB and NF-κB expressions in the cerebral cortex of AD mice models(P＜0.05).Conclusion In AlCl3 induced AD mice,TMP can remarkably enhance the learning and memory abilities,presumably in relation to raise the activity of SOD,reduce the activity of AChE,the levels of MDA and the expressions of AB and NF-κB in the brain.

Objective To systematically assess the relationship between oral administration of aspirin and survival benefit for patients with colorec?tal cancer(CRC)by meta?analysis. Methods Relevant studies were identified through searching PubMed and EMBASE. Random?effects model was derived to composite the pooled hazard ratio for overall mortality and CRC?specific mortality. The subgroup analysis was conducted for included data,and the bias analysis was reported. Results Thirteen studies on aspirin therapy were finally included in this meta?analysis. The overall surviv?al benefit associated with oral administration of aspirin represented an HR of 0.83(95%CI:0.71?0.96). Oral administration of aspirin was also asso?ciated with CRC?specific survival(HR=0.77,95%CI:0.64?0.93). No evidence was observed of an association between prediagnostic aspirin use and CRC overall survival(HR=1.00,95%CI:0.85?1.18)or CRC?specific survival(HR=0.97,95%CI:0.83?1.13). Conclusion These findings provide further indication that post?diagnostic aspirin therapy can improve CRC prognosis.
