Objective:
To investigate the development of public health human resource of the Centers for Disease Control and Prevention (CDCs) in Zhejiang Province from 2016 to 2020, so as to put forward the strategies for the talent team construction of CDCs.
Methods:
The general information of personnel of CDCs in Zhejiang Province from 2016 to 2020 was collected through China Information System for Disease Control and Prevention. A questionnaire survey and a qualitative interview were conducted to collect the data of staffing, talent training, salary and employee turnover, and to analyze the development of the talent team of CDCs.
Results:
By 2020, there were 105 CDCs, including 1 provincial, 11 prefectural and 93 county-level CDCs, and 5 277 staff on-the-job. From 2016 to 2020, the number of staff per 10 000 permanent residents in the province, prefecture and county levels were 0.062-0.070, 0.170-0.188 and 0.585-0.604, respectively, which did not meet the standard for the personnel establishment in Zhejiang CDCs; the proportion of the staff with bachelor degree or above increased from 90.05% to 94.25%; the proportion of the health professionals decreased from 82.91% to 80.01%; the proportion of the staff with senior professional titles increased from 35.20% to 45.25%. The results of the qualitative interview indicated a lack of health professionals and high-end talents, a gap between the approved staffing and post requirements, as well as demands for a stable team and higher pay.
Conclusion
From 2016 to 2020, the structure of educational background, major and professional title among the on-the-job staff of CDCs in Zhejiang Province has been improving; however, the total allocation of human resource is insufficient, and the stability and treatment of staff need to be further improved.

Objective To observe the clinical effect of acupuncture combined with vibroacoustic therapy on upper limb spasticity post stroke. Methods From November, 2014 to November, 2015, 90 patients with upper limb spasticity post stroke were randomized into treat-ment group (acupuncture combined with vibroacoustic therapy), control 1 group (simple vibroacoustic therapy) and control 2 group (simple acupuncture) with 30 cases in each group. All the patients accepted routine fundamental treatment and rehabilitation training. The modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) were used to assess the upper limb muscle ten-sion, motor function and activities of daily living before and four weeks after treatment. Results After treatment, MAS score decreased in all groups (Z>3.067, P<0.001), and FMA score and MBI score increased (t>3.326, P<0.01). MAS score decreased more (Z>2.919, P<0.01), and FMA score and MBI score increased more (P<0.05) in the treatment group than in the control groups after treatment. However, there was no significant difference between the control groups (P>0.05). The total effective rate was 80%in the treatment group, 50%in the control group 1 and 53%in the control group 2 (χ2=8.573, P=0.014), respectively. Conclusion Acupuncture combined with vibroacoustic therapy can alleviate the upper limb spasticity, and promote the recovery of motor function and activities of daily living.

Objective To investigate the prognostic value of heart rate turbulence (HRT) in patients with chronic heart failure (CHF). Methods From October 2006 to May 2009, a total of 96 elderly CHF inpatients were selected, and the clinic data were recorded. Based on the echocardiogram and dynamic electrocardiogram, the differences of sinus HRT index of patients with different cardiac function classification were analyzed. During 9-28 months medical follow-up, the treatment endpoint was death from heart disease. Based on Logisitc regression, the prognostic values of HRT, age, hypertension, diabetes, myocardial infarction (MI), left ventricular ejection fraction, ACEI and β- adrenergic blocker for death of CHF patients were analyzed.Results There was no significant difference in HRT between grade Ⅱ and grade Ⅲ cardiac function (χ~2 = 1.60, P>0. 05), and between grade Ⅲ and grade Ⅳ cardiac function (χ~2 = 1.43, P>0. 05). But there was significant difference in HRT between grade Ⅱ and grade Ⅳ cardiac function patients χ~2 =9.84, P<0. 05), and HRT was weaken in grade Ⅳ group. The average follow-up time was (18. 0±9.6) months. Of all 96 patients, there were 34 dead of heart disease. There were correlations of death of CHF with HRT, low LVEF (≤ 45%), age (≥65 years), diabetes, MI and classification of heart function. Conclusions The sinus HRT in CHF patients has a favorable prognostic value.

Objective To investigate the efficacy of progressive resistance exercise for improving the lower limb motor function of hemiplegic stroke patients. Methods Eighty-nine hemiplegic patients were randomly divided into a treatment group (n =46) and a control group ( n = 43 ) . Both groups received routine rehabilitation training, while the treatment group also undertook progressive resistance training. The control group received extra quadriceps femoris training. Before and after the treatment, motor function was evaluated with the Fugl-Meyer lower limb assessment, functional ambulation category (FAC) classification and the modified Barthel index (MBI). Results Before intervention, there were no significant differences between the two groups in any of the assessments. Four weeks later, all the assessment scores obtained with the Fugl-Meyer lower limb assessment, FCA classification and MBI in the treatment group were significantly better than those in the control group. Conclusion Progressive resistance training combined with routine rehabilitation treatment can improve motor function in the lower limbs, ambulation and ability in the activities of daily living of hemiplegic patients after stroke.

Survivin-D53A (SVV-D53A) is a dominant-negative mutant survivin, which represents a potential promising target for cancer gene therapy. The present study was designed to determine whether SVV-D53A plasmid encapsuled by DOTAP: Chol liposome would have the anti-tumor activity against SPC-A1 lung adenocarcinoma, and to detect the possible mechanisms. In our experiment, SPC-A1 cells were transfected in vitro with SVV-D53A plasmid and examined for protein expression by Western blot, then flow cytometric analysis was used to detect apoptosis. SPC-A1 lung adenocarcinoma xenografts were established in vivo in the nude mice, which received the i. v. administrations of SVV-D53A plasmid/liposome complexes. After mice were sacrificed, the paraffin-embedded tumor tissue sections were used for proliferating cell nuclear antigen (PCNA) expression and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Compared with the control group, the mice treated with SVV-D53A plasmid had an obviously reduced tumor volume, with high level of apoptosis and decreased cell proliferation in tumor tissue. The research results proved that the administration of SVV-D53A plasmid resulted in significant inhibition of SPC-A1 cells both in vitro and in vivo. The functional mechanism is that the anti-tumor response causes and induces tumor cell apoptosis.
