Objective : To investigate the epidemiological characteristics of influenza among the elderly in Heilongjiang Province from 2017 to 2021 (April 2017 to March 2022), so as to provide insights into influenza control among the elderly. Methods : The data pertaining to surveillance of patients with influenza-like illness (ILI) at ages of 60 years and older in Heilongjiang Province from 2017 to 2021 were retrieved from Chinese Influenza Surveillance Information Management, and the temporal distribution of ILI cases and the results of influenza virus tests were descriptively analyzed. Results : Totally 26 908 ILI cases at ages of 60 years and older were reported in Heilongjiang Province from 2017 to 2021, with an ILI prevalence rate of 0.17%. The prevalence of ILI appeared a tendency towards a rise in Heilongjiang Province from 2017 to 2021 (χ2trend=268.554, P<0.001), and the epidemic peaked in the 3rd to 7th weeks of 2019 and 2020. The overall positive rate of influenza virus was 6.80%, and the positive rate of influenza virus showed a tendency towards a decline from 2017 to 2021 (χ2trend=425.268, P<0.001). Influenza A (H1N1) pdm09 (46.82%) and A (H3N2) (22.79%), as well as influenza B virus lineages B/Victoria (12.11%) and B/Yamagata (18.28%) were predominant types, which changes among the study period. The detection of influenza virus-positive samples peaked from December to March of the next year, and a high positive rate of influenza virus was detected in Hegang (12.35%), Heihe (11.47%) and Daqing cities (11.07%). There was no significant correlation between the prevalence of ILI and the positive rate of influenza virus in Heilongjiang Province from 2017 to 2021 (rs=-0.800, P=0.104). Conclusions The prevalence of ILI appeared a tendency towards a rise among the elderly at ages of 60 years and older in Heilongjiang Province from 2017 to 2021, and the epidemic peaked in winter and spring. Influenza A (H1N1) pdm09, A (H3N2), B/Victoria, B/Yamagata were alternately prevalent and there was no obvious correlation between ILI prevalence and the positive rate of influenza virus.

OBJECTIVE:To investigate new thought and method for improving the practice teaching effect of pharmacy under-graduates under the collaboration of medicine and education. METHODS:The training objectives of pharmacist team,the current sit-uations and problems of teaching that existing in the institute of pharmacy and the requirement of talents in the work were summa-rized and investigated,and then reform targets and measures were put forward. RESULTS:Training for pharmacists tream gradual-ly movedcloser to clinical pharmacists in China.The teaching work in the pharmacy department of our hospital was relatively com-plete,including relevant teaching system,practice systems and processes,training program for clinical pharmacists and develop-ment of workflow;however,there still remained some problems,including lacking of professional quality training,suitable cours-es,effective interactive medical and education scientific assessment mode and no attention for the training of clinical thinking and school-university research thinking. The above-mentioned problems needed to be solved by reforming internship tutorial system and improving the contents,establishing the school-hospital united system,emphasizing the connection between schools and teaching bases,establishing integrated teaching evaluation system and assessment criteria,strengthening clinical experience and training for clinical thinking by the teaching mode of physicians and pharmacists. CONCLUSIONS:Strengthening the collaboration of medicine and education and improving the training standards and evaluation system are helpful for improving the practice teaching quality of pharmacy undergraduates.

Objective To evaluate the role of spinal dopamine D2 receptors in a rat model of neuropathic pain.Methods Thirty healthy male Sprague-Dawley rats,aged 6-8 weeks,weighing 180-200 g,wcre randomly divided into 5 groups (n =6 each) using a random number table:control group (group C),sham operation group (group S),neuropathic pain group (group NP),normal saline group (group N) and dopamine D2 receptor agonist quinpirole group (group Q).Neuropathic pain was produced by chronic constriction injury of the sciatic nerve (CCI) in rats anesthetized with intraperitoneal 2％ pentobarbital sodium 40 mg/kg.At 7 days after CCI,normal saline 10 μl was injected intrathecally over 30 s in group N,and quinpirole 10 μg (in 10 μl of normal saline) was injected intrathecally over 30 s in group Q.At 1 day before CCI,3 and 7 days aher CCI,and 30 min and 1,2,4,8 and 16 h after administration,mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured.Results There was no significant difference in MWT and TWL at each time point between group C and group S.MWT was significantly lower,and TWL was shorter at T1-8 in NP,N and Q groups than in C and S groups.Compared with group N,no significant change was found in MWT and TWL at each time point in N group,and MWT was significantly increased,and TWL was prolonged at T4-6 in group Q.Conclusion Inhibited function of spinal dopamine D2 receptors is involved in the maintenance of neuropathic pain in rats.

Objective:To study the effect of Snyder's hope theory nursing on the scores of psychological stress, quality of life and neurological function in patients with acute hypertensive cerebral hemorrhage.Methods:From June 2017 to December 2018, 100 patients with acute hypertensive cerebral hemorrhage in the Second Affiliated Hospital of Xi′an Jiaotong University were selected as the study object. According to the random number table, the patients were divided into observation group (50 cases) and control group (50 cases).The patients in the control group were given routine rehabilitation nursing mode, and the patients in the observation group received Snyder′s hope theory nursing on the basis of the control group. The rescue time, the recovery time and the incidence of complications of the two groups were compared. The degree of anxiety and depression, neurological function, quality of life of the patients were evaluated by Self-rating Anxiety Scale(SAS), Self-rating Depression Scale(SDS), National Institutes of Health Stroke Scale(NHISS), Glasgow Coma Scale(GCS) and SF-36.Results:The rescue time and recovery time were (58.13±10.36) min, (12.7±5.3) d in the observation group, and (85.71±8.30) min, (21.1±3.3) d in the control group, and there were significant differences between the two groups ( t values were 14.691, 10.646, P < 0.05).There was no significant difference in SAS, SDS, NIHSS, GCS, SF-36 score before intervention between the two groups ( P> 0.05).The scores of SAS, NIHSS, GCS after intervention were (40.56±1.72), (11.23±2.85), (13.12±4.11) points in the observation group, and (46.56±1.62), (14.97±4.55), (11.13±3.15) points in the control group, and there were significant differences between the two groups ( t values were 17.956, 4.926, 3.212, P<0.01). There were significant differences in SF-36 after intervention between the two groups( t values were 7.124-13.014, all P<0.01). The incidence of complications was 8.0%(4/50) in the observation group, and 24.0%(12/50) in the control group, and there was significant difference between the two groups( χ2 value was 4.762, P<0.05). Conclusions:Snyder's hope theory nursing has a significant effect on the improvement of anxiety and depression in patients with acute hypertensive cerebral hemorrhage, which is worth popularizing.

Objective To assess the efficacy and safety of various spectrum lasers in the treatment of acne vulgaris. Methods Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Library (2009, 6 issues), PubMcd, Embase, China Biomedical Literature Database, China Journal Full Text Database, Chinese Scientific Journals Full Text Database. Retrieval time was up to June, 2009. Randomized controlled trials (RCTs) of lasers for acne vulgaris were included. Results Twelve RCTs totaling 367 patients were included. Because the lack of clinical homogeneity, only descriptive analysis was conducted. Acne lesion counts improved significantly with laser therapy. Adverse effects were limited to transient erythema and edema at treatment sites. Treatment-related pains were well tolerated. Conclusions Current evidence demonstrates that all type lasers in treating acne vulgaris is safe and efficacy. However, higher quality RCT research would be needed to verify the effects and status of lasers on acne vulgaris.
