Objective To investigate changes in the firing activities of nucleus accumbens (NAc)neurons and their response to 5-HT7 receptor stimulation in a rat model of Parkinson’s disease (PD).Methods The firing activities and response of NAc neurons to 5-HT7 receptor agonist in PD rats were recorded by in vivo electroneurophysiology and neuropharmacology and then were compared with those in the sham group.Results The mean firing rate of NAc neurons was (5.46 ±0.88)Hz in the sham rats and (3.77 ±0.48)Hz in the PD rats. The firing rate of NAc neurons increased significantly compared with that in the sham rats (P <0.05).In PD rats, 65% of NAc neurons fired in bursts and 35% fired irregularly.However,in the sham rats,57.5% of NAc neurons fired in bursts and 42.5% fired irregularly.There was no significant difference in the firing pattern of NAc neurons between the PD and sham rats (P >0.05 ).Systemic administration of 5-HT7 receptor agonist AS1 9 increased the firing rate of NAc neurons in the sham and PD rats.This excitation was significant at a high dose of 1 60 μg/kg for NAc neurons in the sham rats (P <0.05).However,the excitation produced by AS1 9 was significant at a high dose of 80 μg/kg in PD rats (P <0.05).The cumulative dose-produced excitation in the PD rats was lower than that in the sham rats.The effects induced by AS1 9 were reversed by the 5-HT7 receptor antagonist SB269970 in both groups.Conclusion The reinforced firing activity of NAc neurons might be mediated by 5-HT7 receptor in the neurons of PD rats.

Objective:To seek the effect of group education under the BOPPPS model(bridge-in, objective, pre-assessment, participatory learning, post-assessment, summary) on the breastfeeding competency of first gestation women, to improve the breastfeeding competency of first gestation women and promote the realization of postpartum breastfeeding.Methods:Eighty-one first gestation women were chosen from the gestation class of the First Affiliated Hospital of Shanxi Medical University, the quasi-experimental research method was adopted, 40 women from January to February 2022 were involved in the control group and 41 women from May to June 2022 were involved in the intervention group. The control group was assigned common education, while the intervention group was assigned group education based on BOPPPS model. Breastfeeding Competency Scale (BCS) and breastfeeding family support questionnaire were used to compare breastfeeding competency and family support level of the two groups before and after intervention, and the skin contact rate at 1 hour after delivery and the pure breastfeeding rate at 42 days after delivery were compared between the two groups.Results:Before intervention, there was no significant difference in breastfeeding competency and family support level between the two groups (all P>0.05). After 4 weeks of intervention, the scores of breastfeeding competency and family support were (147.59 ± 13.50), (3.16 ± 0.18) points in the intervention group, more than those in the control group (125.48 ± 16.87), (2.87 ± 0.22) points, the differences were statistically significant between the two groups ( t=-6.52, -6.30, both P<0.05). The skin contact rate at 1 hour after delivery and the pure breastfeeding rate at 42 days postpartum were 75.6%(31/41), 53.7%(22/41) in the intervention group, more than those in the control group 52.5%(21/40), 30.0%(12/40), the differences were statistically significant between the two groups ( χ 2=4.71, 4.65, both P<0.05). Conclusions:Group education based on BOPPPS model can improve the level of breastfeeding competency and family support of gestation women. It increases the skin contact rate, and plays a good role in promoting the increase of pure breastfeeding rate.

Objective To evaluate the effect of interventions for improving the management of cardiovascular risk factors in general practitioners. Methods Interventions were conducted in thirty-five community health service centers in Chaoyang District of Beijing using simplified clinical pathways,clinical decision support systems, service quality evaluation index and feedback mechanism, and quality-related motivation system. The research was divided into three periods, which were indicated as before the interventions (2014.1-6), after the first intervention (2014.8-10), and after the second intervention (2014.12-2015.2), according to the community service center outpatient clinic, the computer randomly selected 2 100, 2 089 and 2 052 subjects. With the method of retrospective case review, historical case records of each selected case were extracted, and the changes in KPIs before and after interventions were evaluated.Results After two cycles of intervention,compared with before the interventions,the capability of general practitioners to record hypertension(99.9% vs.70.5%,χ2=708.9),diabetes(99.6% vs.41.5%,χ2=1691.1),hyperlipidemia(99.5% vs.37.0%,χ2=1854.9),coronary atherosclerotic heart disease(CHD)(99.6% vs. 54.3%, χ2=1190.9), and cerebral hemorrhagic stroke (99.4% vs. 39.7%, χ2=1736.2) had significantly increased (P<0.001). Records of other risk factors, for instance, height and weight (81.4% vs. 72.2%, χ2=50.3),smoking(70.0% vs.0.1%,χ2=2 179.2),and health education including recommended physical activity (75.0% vs. 68.2%, χ2=24.0) and weight control (75.4% vs. 16.2%, χ2=1 467.1) significantly increased (P<0.001). The proportion of patients with hypertension who did not use antihypertensive drugs was 31.6% before the intervention;in the first period of intervention,it reduced to 20.2%,and in the second period after the intervention it was 25.8%. Cases of CHD, stroke, diabetes, patients taking aspirin, beta blockers, angiotensin converting enzyme inhibitors(ACEI)or angiotensin receptor blockers(ARB)in proportion to the class of drugs, and statins increased (P<0.05); the coronary atherosclerosis heart disease patients with beta-blockers utility ratio was 20.2% before the intervention, and in the second cycle it was up to 27.9% after the intervention;for patients with diabetes statins utility ratio was 32.1% before the intervention,and in the second cycle it was up to 40.9% after the intervention.Conclusion Adoption and implementation of a series of interventions such as simplified clinical pathways,clinical decision support systems,service quality evaluation index and feedback mechanism, and quality-related motivation system will be beneficial to improve the capability of general practitioners to manage the cardiovascular disease risk factors,which are implied to be effective methods for managing chronic diseases.

Objective To evaluate the diagnostic efficiency and prognostic value of 18F-fluorodeoxyglucose (FDG) PET/CT for response assessment after treatment in patients with diffuse large B-cell lymphoma (DLBCL) when using the Deauville criteria and International Harmonization Project (IHP) criteria.Methods A total of 212 patients (119 males,93 males,average age:59.6(10-88) years) with DLBCL from February 2010 to June 2018 were analyzed.All subjects underwent restaging PET/CT after treatment.Images were evaluated with the IHP criteria,Deauville score of 3-5 (DC3) and Deauville score of 4-5 (DC4).The diagnostic efficiency of the 3 criteria for treatment effect was assessed and follow-up results were used as the gold standard.Spearman rank correlation analysis was used.Progression-free survival (PFS) and overall survival (OS) were analyzed by Kaplan-Meier analysis and Cox proportional hazards model.Results The positive predictive value and accuracy of DC4 for treatment effect evaluation were 96.8％(61/63) and 94.3％(200/212),those of IHP criteria were 75.3％(67/89) and 87.7％(186/212)respectively,and those of DC3 were 82.9％ (68/82) and 92.0％ (195/212) respectively.IHP criteria results and Deauville scores were correlated(rs =0.926,P＜0.05).The 2-year PFS rates in IHP-,DC3-and CD4-positive groups were 78.7％,76.5％ and 69.8％,respectively,and those in IHP-,DC3-and CD4-negative groups were significantly higher (95.6％,94.7％,97.2％;x2=14.415,18.293 and 26.920,all P＜0.05).The similar results were found for OS rates (x2 =9.597,11.149 and 17.416,all P＜0.05).The 2-year PFS rates in Deauville score of 1,2,3,4,5 groups were 95.3％,91.7％,93.3％,88.9％ and 55.6％ respectively (x2 =48.199,P＜0.05).Cox-regression analysis showed significant correlation between Deauville criteria and 2-year PFS rate (P＜0.05).Conclusions PET/CT with DC4,DC3 and IHP criteria have high predictive values for treatment outcome,and DC4 is the best.Cox regression analysis shows significant risk of progression by Deauville criteria.

Objective:To analyze the vaginal microecological status of vaginitis population and non-vaginitis population of gynecological female outpatients.Methods:A total of 30 265 women who visited the gynecological outpatient clinic of Beijing Obstetrics and Gynecology Hospital from December 2018 to December 2020 completed vaginal microecological examination. After removing the follow-up patients, 23 181 women were divided into group with symptoms and signs of vaginitis (6 697 cases) and group without symptoms and signs of vaginitis (16 484 cases), according to whether the women with symptoms and signs of vaginitis or not. And the vaginal microecological status of the two groups was compared and analyzed.Results:(1) The total detection rate of vaginitis in the initial women was 34.87% (8 083/23 181), of which 46.10% (3 087/6 697) in group with symptoms and signs of vaginitis and 30.31% (4 996/16 484) in group without symptoms and signs of vaginitis, nearly 1/3 of the gynecological outpatients without signs and symptoms of vaginitis had vaginitis. (2) Among the types of simple vaginitis, vulvovaginal candidiasis (VVC) was the most frequent in group with symptoms and signs of vaginitis (16.01%, 1 072/6 697), followed by aerobic vaginitis (AV; 12.83%, 859/6 697), with significant differences compared with group without symptoms and signs of vaginitis (all P<0.001). There were no statistical differences between the two groups of bacterial vaginosis (BV) and trichomonal vaginitis (TV), indicating that BV and TV were more likely to be neglected (all P>0.05). (3) The proportion of various combinations of vaginitis among 2 632 cases of mixed vaginitis were, in descending order: BV+AV, VVC+AV, BV+AV+VVC, AV+TV, AV+TV+BV, BV+VVC. (4) Microecological analysis of 15 098 cases diagnosed with non-vaginitis had normal flora (including those with normal flora and those with normal flora but decreased function) in 14 013 cases (92.81%, 14 013/15 098), abnormal flora in 429 cases (2.84%, 429/15 098) and the BV intermediate in 656 cases (4.34%, 656/15 098); this indicated that the vast majority of the microecological tests were normal in the vaginal microbiota of those without vaginitis. Conclusions:Microecological examination could diagnose multiple pathogenic infections at once, and is especially important as a guide for the definitive diagnosis of mixed vaginitis and vaginitis with atypical clinical symptoms. Vaginal infections such as BV and TV that are easily overlooked should be concerned.
