BACKGROUND: It is well known that central noradrenergic system takes part in learning and memory, but there are a few researches focused on the effects of impairing the central noradrenergic system on rat' s P3-like cognitive potential.OBJECTIVE: To study the effects of impairing the central noradrenergic system on rat's P3-like cognitive potential.DESIGN: Randomized controlled study based on the experimental animals.SETTING: Department of physiology in a medical college of a university.MATERIALS: Totally 30 male SD rats, clean degree, weighing from 500 to 600 g, were selected from the Experimental Animal Center of Sun Yat-sen Medical University(certificate: 26-99A018), drank freely and fed timely under the normal condition. After Y-maze test of all the rats, 24 rats with normal learning and memory function, which met the criteria specified in the description of Y-maze test, were randomly divided into three groups(8 rats in each group): control group, 6-oxidopamine (6-OHDA) injection group and saline control group.INTERVENTIONS: The models of central norndrenergic system impairment were made by injecting 6-hydroxysopamine(6-OHDA) into the bilateral dorsal noradrenergic bundle in dentate granule(DG). Then Y-type maze test and elicitation of P3-likewere carried out respectively before and after the models were built.MAIN OUTCOME MEASURES: Main outcome: P3-like latency, total reaction time(TRT) and error number(EN). Secondary outcome: Results of P3-like test recorded in the 12 days after the models were built.RESULTS: As compared with the controls, the model rats' P3-like latency and total reaction time(TRT) prolonged and error number(EN) increased statistically ( P ＜ 0.05 ).CONCLUSION: Central NE takes part in the activities of learning and memory and plays a certain role in the production and integration of P3 -like.

Objective To explore the clinical effect of mifepristone combined with misoprostol for termina-tion of pregnancy in high risk pregnant women and provide reference for clinical treatment.Methods 182 cases of high -risk maternal were divided into observation group and control group by the random number table method,each group 91 cases.The control group was treated with conventional abortion termination of pregnancy,the observation group was treated with the artificial abortion before oral administration of mifepristone tablets and misoprostol tablets. The operation time,the amount of blood loss,the degree of pain,the degree of cervical softening and the occurrence of complications of induced abortion were compared between the two groups.Results The operation time of the observa-tion group was (2.21 ±1.41)min,intraoperative bleeding was (15.29 ±4.06)mL,which were significantly less than those of the control group (t =7.122,8.256,all P <0.05);The pain degree grade I in the observation group was 58.24%,which was significantly higher than that in the control group,grade III accounted for 5.49%,which was sig-nificantly lower than the that in the control group (χ2 =44.887,44.121,all P <0.05),the observation group of cer-vical softening full was 59 cases,full softening rate was 64.84% and the control group in the cervical softening full was 41 cases,softening full rate was 45.05%.Fully softening rate in the observation group was significantly higher than that in the control group (χ2 =7.191,8.411,P <0.05),the control group,the incidence of uterine perforation in 2 cases,the occurrence of artificial abortion syndrome 7 cases,the incidence of complications for 9.89%,the obser-vation group had no uterine perforation occurred,1 case of artificial abortion syndrome and complications occurred rate was 1.10%.The incidence of complications in the observation group was significantly lower than that in the control group (χ2 =6.772,P <0.05).Conclusion Mifepristone combined with misoprostol for high -risk maternal termi-nation of pregnancy could significantly shorten the artificial abortion operation time,reduce intraoperative blood loss, reduce the patient pain,reduce the incidence of complications.

Objective To explore the clinical and coronary angiographic characteristics in acute myocardial infarction (AMI) patients with new-onset atrial ifbrillation in early or later stages. Methods From Jun. 2010 to Jun. 2013, 1358 cases of AMI were hospitalized in which 88 were proved to have AMI complicated with new-onset atrial ifbrillation. Eligible patients were divided into early onset group (group1, n=40 cases) and the later onset group (group2, n=48 cases) according to the occurrence of atrial ifbrillation within or after 24 hours of admission. The clinical characteristics and the pathological changes of coronary arteries of the two groups were compared respectively. Results The incidence of inferior wall AMI was signiifcantly higher in group 1. The incidence of anterior wall AMI was signiifcantly higher in group 2 (P<0.05). The incidence of congestive heart failure, the incidence of three-vessel lesions and the in-hospital mortality in group 2 were higher than which in group 1 (P < 0.05). Conclusions The new-onset atrial ifbrillation in different stages may be regarded as a useful indicator for evaluating the clinical characteristic and the infarct-related coronary artery lesions and prognosis of patients with AMI.

Objective To study cervical human papillomavirus (HPV) infection and genotype distribution characteristics in patients with vaginal disease.Methods The PCR dot blot was used to carry out HPV detection of cervical exfoliated cells in 816 women with cervical lesions in the hospital, and 23 kinds of HPV genotypes were identified.Results Among the 816 cases receiving HPV type detection, HPV of 532 cases (65.20%) was positive, including 371 cases (69.74%) with low-risk HPV (HR-HPV) infection, 161 cases (30.26%) with low-risk HPV infection (LR-HPV) (P<0.05).The HPV infection rate below 45 years old was relatively higher.The HPV infection rate in patients with cervical cancer (97.10%) was higher than that in patients with cervical intraepithelial neoplasia (CIN) II -III (80.54%), patients with CIN Ⅰ(41.55%) and patients with cervicitis (17.20%) (P<0.05).The top five types of HPV infection were HPV16, 58, 18, 11 and 56 type, respectively.The single infection rate (79.70%) was higher than multiple infection rate (20.30%) (P<0.05); HR-HPV infection was the main infection in single infection, and double infection was the main infection in multiple infection.Conclusion Below 45 years old women are the high-risk groups of HPV infection.16, 58, 18, 11 and 56 are the main types of HPV infection.The infection rates of patients with cervical cancer and precancerous lesions are relatively higher.Paying attention to the screening of HPV infection has positive significance in the prevention and treatment of cervical cancer.
