Objective: To systematically evaluate the willingness to receive influenza vaccines among Chinese medical staff, so as to provide the evidence for developing the influenza vaccination strategy and improving the coverage of influenza vaccination among medical staff. Methods: Publications pertaining to the willingness to receive influenza vaccines among Chinese medical staff were retrieved from international and national databases from January 1, 2010 to October 1, 2023, including CNKI, Wanfang Data, VIP, SinoMed, PubMed, Web of Science and Embase. A meta-analysis was performed using the software Stata 17.0, sensitivity analysis was performed using the leave-one-out method, and the publication bias was evaluated using Funnel plot. Results: Totally 674 publications were retrieved, and 17 case-control studies were finally enrolled, with 23 697 participants. Meta-analysis showed that the rate of willingness to receive influenza vaccines among medical staff in China was 52.8% (95%CI: 41.3%-64.4%). The rates of willingness to receive influenza vaccines were 40.2% (95%CI: 28.5%-51.8%) in 2019 and before and 67.2% (95%CI: 56.5%-77.9%) in 2020 and beyond; 54.6% (95%CI: 44.2%-65.0%) in men and 56.8% (95%CI: 49.3%-64.4%) in women; 53.6% (95%CI: 40.9%-66.2%) in doctors, 53.9% (95%CI: 41.0%-66.8%) in nurses, 62.8% (95%CI: 46.2%-79.3%) in technicians and 53.1% (95%CI: 36.1%-70.0%) in administrative and logistical staff; 77.4% (95%CI: 63.7%-91.2%) and 43.3% (95%CI: 30.5%-56.1%) in staff with and without a history of influenza vaccination; 49.8% (95%CI: 27.3%-72.3%) and 58.3% (95%CI: 43.9%-72.6%) in studies with a sample size of <1 000 and ≥1 000, and these differences were statistically significant (all P<0.05). Sensitivity analysis showed robustness of results, and Funnel plot showed publication bias. Conclusion The rates of willingness to receive influenza vaccines among medical staff in China ranged from 41.3% to 64.4%, and were lower in studies in 2019 and before, in men, in administrative and logistical staff and in staff without a history of influenza vaccination.

Objective To evaluate left ventricular(LV) twist and untwist using velocity vector imaging(VVI) in patients with apical hypertrophic cardiomyopathy (ApHCM). Methods Twenty-three patients diagnosed with ApHCM were consecutively enrolled and compared with normal controls. After a standard echocardiographic examination, parasternal basal and apical short-axis planes were scanned to quantify LV rotations,twist and LV untwist using VVI. Results Compared with the normal controls, the rotation and rotaional velocity of apical subendocardial myocardium were markedly decreased in ApHCM patients during the period of systole ( P＜0.05) ,but the decreases in basal planes were not significant. As a consequence,LV twist was significantly lower in ApHCM patients (P＜ 0.05). Compared to normal controls,the velocity of LV untwisting was also significantly decreased in ApHCM patients ( P＜0.05).Conclusions The twist and untwist of LV subendocardial myocardium were decreased in ApHCM patients.VVI is a useful method to assess the characteristics of LV twist and untwist in ApHCM patients.

Their intake of fat ,protein ,retinol equivalent ,niacin ,vitamin E ,sodium and iron were too much .Instead ,they ate less ascorbic acid;only the intake of energy ,riboflavin and thiamine were appropriate .Conclusion The one meal dietary structure of hotel customers is not appropriate ,while nutrition collocation is not reasonable .It is necessary to promote nutrition and health education and some intervention measures must be taken .

Objective To evaluate the echocardiographic features of apical hypertrophic cardiomyopathy( ApHCM). Methods Twenty-seven patients with ApHCM including 21 men and 6 women, average age (42.7 ± 5. 1 ) years old were followed up from 1995 to 2008 to investigate the clinical, electroeardiographic and echocardiographic features. Results The major features of ECG were increased R amplitude( V_4 > V_5 > V_3)and inverteted T wave(especially in V_(3-5) leads and the voltage of the inverteted T waves may be up to ≥10 mm). The major feature of echocardiography was the thickening of left ventricular apical wall to 15 - 37 ( 18. 0± 3. 3 ) mm. The final follow up showed that the mean thickness of the apical wall was ( 19. 7 ±3. 7) mm. The ratio of the thickness of left ventricular apical wall to posterior wall before and after the follow up was 1. 7 ±0. 3 and 1. 9 ±0. 9 respectively, with significant statistical difference ( P < 0. 05). There was no difference in the left ventricular end-diastolic dimension and left ventricular ejection fraction. The main cardiovascular events were atrial fibrillation ( 16 cases) , heart failure of NYHA ID-IV class (3 cases) , anterior wall myocardial infarction ( 1 case) and sudden death ( 1 case). Conclusions The final diagnosis of ApHCM depends on the characteristic inverteted T wave in ECG and apical hypertrophy in echocardiography. The prognosis of ApHCM is rather good for its progression is relatively slow.

Objective To investigate the expression and the role of Tim-3 and Th-17 in ITP patients and to research their clinical application. Methods Total 42 active ITP patients and 39 healthy donors were recruited in this research. The expressions of Th17 and CD4+ CD25+ Treg were measured with flow cytometer. IL-17, IFN-γ levels as well as IL-4 plasma levels were determined by ELISA. The mRNA expression of Tim-3, IFN-γ, IL-4 and T-bet were measured using RT-PCR in all samples. Results The expression of Th17 cells in ITP patients was (2.41 ± 1.43 )%, which was significantly higher than control group ( 1.08 ± 0.59)% ( t = 5.35, P < 0.05 ). But the percentage of Treg in ITP patients was ( 1.64 ±0.74)%, which was lower than control group (3.12 ±0.52)% (t = 10.33, P <0.05). The levels of IL-17 in plasma of ITP and controls were ( 14.42 ±6.37) ng/L and ( 13.91 ±4.47) ng/L respectively (t =0.42, P > 0.05). The level of IFN-γin plasma of ITP was (55.74 ± 15.25 ) ng/L, which was higher than control group (31.33 ± 12.99) ng/L (t = 7.72, P < 0.05 ). The level of IL-4 in the plasma of ITP was (7.42 ± 1.50) ng/L, which was lower than controls ( 18.17 ± 5.19) ng/L ( t = 12.87, P ＜ 0.05 ). Both IFN-γand T-bet mRNA levels were up-regulated in active ITP patients by the factor ( 8.57 ± 3.44 ) -fold and (3.34 ± 1.32)-fold than control group (t = 13.21,6.41 ,P <0.05). The decreases observed in IL-4 and Tim-3 were (0.25 ±0.15 )-fold and (0.29 ±0.15)-fold respectively in ITP patients compared with control group (t=10.02,9.61,P＜0.05 ). Conclusion The imbalance of Th17/Treg and the decrease of Tim-3 might be important determinants in the evolution of ITP.

Activity of IL-1 produced by peripheral blood monocytes stimulated with lipopolysaccharide in vitro was detected from 17 acute cases, 14 chronic cases and 19 advanced cases of schistosomiasis japonica. It was found that the level of IL-1 was significantly increased and positively related to the body tempereture in the group with acute schistosomiasis. The activity of IL-1 was statistically reduced in the chronic and advanced groups, especially in the latter. After inhibiting the synthesis of prostaglandin with indomethacin, the level of IL-1 was significantly increased in three groups of patients, but no apparent change in the normal contro group. The results indicate that IL-1 may play an important role in inducing the inflammatory reaction in patients with acute schistosomiasis japonica and in the immunoregulation in the chronic stage. The changes of IL-1 activity in patients with schistosomiasis japonica may be closely related to prostaglandin.

Objective:To understand the hearing loss status of workers exposed to noise, and provide a scientific basis for formulating effective prevention and control strategies.Methods:From Januaryl to October 31 , 2018, through the occupational hazard declaration and record management system of the workplace and the health checkup system , the basic information and physical examination information of 7806 noise-exposed workers in 136 companies in Zhuzhou City in 2018 and the related information about the industry, type, and scale of the enterprises were collected. The χ 2 test was used to analyze the occupational health monitoring data of the noise-exposed workers. Results:The average age of 7806 workers in Zhuzhou was(36. 1±9. 3) years, and the working age was 7. 0(3. 0, 11. 0) years. And 1 270 workers with noise induced hearing loss(NIHL) were detected, including 51 suspected occupational noise deafness. The detection rates of NIHL and the suspected occupational noise deafness were 16. 27% , 0. 65% , respectively. The detection rate of noise was 0.01% in 1deaf person. It showed that the male had higher morbidity than the female ( P<0. 05) and the workers with longer exposure time had a higher morbidity ( P<0. 05) . There was a statistically significant difference in the detection rate of NIHL and suspected occupational noise deafness between workers of different types of work ( P<0. 05 ) . It was noted that the morbidity varied in different enterprises, industry types and terms of scales ( P<0. 05 ) . Non- metal ore mining and dressing industry workers had higher NIHL detection rate (33. 33%, 14/42) and small companies workers had higher NIHL detection rate(19. 32%, 296/1532) . There was a statistically significant difference in the detection rate of suspected occupational noise deafness between workers of different economic types of enterprises. There was a high detection rate of suspected occupational noise deafness among workers in private enterprises(1. 29%, 36/2782) . Conclusion:The noise operation in Zhuzhou is seriously endangered.Occupational health protection measures for non-metallic mining and dressing industries, small and private enterprises should be strengthened.Occupational health law enforcement efforts should be strengthened to protect workers' health.

Objective To explore the influences of the path clinical health education on the self-management ability, health-promoting lifestyle, compliance, level of blood lipid in patients with PCI of one-day ward.Methods A total of 93 patients with PCI of one-day ward were selected as subjects and were randomly divided into observation group(n=47, the path of clinical health education) and control group(n=46, routine health education) by means of random number table. And then, we compared the self-care ability, health-promoting lifestyle, medication compliance, and level of blood lipid between two groups before and three months after intervention.Results After intervention, the proportion of low level, medium level, high level of self-care ability was 2.1%, 21.3%, 76.6% in observation group which was better than those(10.9%, 41.3%, 47.8%) in control group. The total score of health-promoting lifestyle in observation group [(157.40±17.86) points] was higher than that [(127.04±11.64) points] in control group. Moreover, the score of medication compliance in observation group [(27.98±3.89) points] was higher than that [(21.00±4.52) points] in control group. Besides, the level of total cholesterol, low density lipoprotein cholesterol, triglyceride in observation group was all lower than those in control. There were statistically significant differences in them between two groups( P<0. 05).Conclusions The path of clinical health education has an important role in improving health-promoting awareness and ability, self-management ability, compliance, level of blood lipid in patients with PCI.

Objective To explore the effect of solution-focused approach on self perceived burden, anxiety and depression in elderly patients with coronary heart disease complicated with type 2 diabetes. Methods From January to June 2016, 76 elderly patients with coronary heart disease complicated with type 2 diabetes from inpatients department of Wuxi Second People's Hospital were selected as the research objects by convenience sampling method. The patients were divided into control group and observation group by random number table, each with 38 cases. Patients in the control group were given routine nursing and patients of the observation group were given solution-focused approach intervention on the basis of routine nursing. Self-perceived burden scale, self-rating anxiety scale and self-rating depression scale were used to evaluate theeffect of intervention.Results Compared with the score before intervention, there was statistical difference in the self-perceived burden score after intervention in two groups (P<0.05). Before intervention, there was no statistical difference in the self-perceived burden score between the patients of the two groups (P>0.05). After 3-month intervention, the self perceived burden score of the observation group was lower than that of the control group (P<0.05). After intervention, there was statistical difference in anxiety and depression score of the intervention group compared with that before intervention (P<0.05). Before the intervention, there was no statistical difference in anxiety and depression of the two groups (P>0.05). After 3-month intervention,the score of anxiety and depression in the intervention group was significantly lower than that in the control group (P<0.05).Conclusions Solution focused approach can reduce the self-perceived burden of the elderly coronary heart disease patients with type 2 diabetes and alleviate the patients' negative emotions effectively.
