A new mutant human papiUomavirus type 16 E7 gene, termed HPV16 HBE7, was isolated from cervical carcinoma biopsy samples from patients in an area with high incidence of cervical cancer (Hubei province, China). A previous study showed that the HPVI6 HBE7 protein was primarily cytoplasmic while wild-type HPV16 E7 protein, termed HPV16 WET, was concentrated in the nucleus. With the aim of studying the biological functions of HPV16 HBE7, the transforming potential of HPV16 HBE7 in NIH/3T3 cells was detected through observation of cell morphology, cell proliferation assay and anchorage-independent growth assay. The effect of HPVI6 HBE7 on cell cycle was examined by flow cytometry. Dual-luciferase reporter assay and RT-PCR were used to investigate the influence of HPVI6 HBE7 protein on the expression of regulation factors associated with GI/S checkpoint. The results showed that HPV16 HBE7 protein, as well as HPV16 WE7 protein, held transformation activity. NIH/3T3 cells expressing HPV16 HBE7 could easily transition from G1 phase into S phase and expressed high level of cyclin A and cdc25A. These results indicated HPV16 mutant E7 protein, located in the cytoplasm, induces oncogenic transformation of NIH/3T3 cells via up-regulation of cyclin A and cdc25A.

Hepatitis B virus (HBV)-specific cytotoxic T lymphocytes (CTLs) are believed to play a major role in viral clearance and disease pathogenesis during HBV infection. To clarify the differences in host immune responses between self-limited and chronic HBV infections, we constructed three HLA-A*0201/HBV tetramers with immunodominant epitopes of core18-27, polymerase 575-583 and envelope 335-343, and analyzed the HBV-specific CTLs in peripheral blood mononuclear cells (PBMCs) from patients infected with HBV. The frequencies and expansion ability of HBV-specific CD8(+) T cells in most self-limited HBV infected individuals were higher than those in chronic HBV-infected patients. HBV-specific CD8(+) T cells could be induced by in vitro peptide stimulation from chronic patients with a low level of serum HBV-DNA but not from those with a high level of serum HBV-DNA. In chronic infection, no significant correlation was found either between the frequencies of HBV-specific CD8(+) T cells and the viral load, or between the frequencies and the levels of alanine transaminase. Our results suggested that the frequencies of HBV-specific CTLs are not the main determinant of immune-mediated protection in chronic HBV infection and immunotherapeutic approaches should be aimed at not only boosting a HBV-specific CD8(+) T response but also improving its function.

Methods:
The demographic features, life style, status of smoking and smoking cessation in hypertensive patients were collected from 69 community health centers in Nanshan District from 2017 to 2019. The gender- and age-specific prevalence of smoking and smoking cessation was estimated among hypertensive patients, and the factors affecting hypertensive patients' smoking and smoking cessation were identified using a multivariable logistic regression model.
Results:
Totally 4 385 patients with hypertension were enrolled, with a mean age of (58.41±11.19) years, and the participants included 2 265 men (51.65%) and 2 120 women (48.35%). There were 724 current smokers, and the prevalence of current smoking was 16.51%, with 29.71% prevalence in males and 2.41% in females. There were 424 hypertensive patients quitting smoking, and the prevalence of smoking cessation was 36.93%, with 38.20% prevalence in males. Multivariable logistic regression analysis identified male ( OR=12.885, 95%CI: 9.567-17.354 ) and drinking ( OR=2.567, 95%CI: 2.118-3.111 ) as facilitating factors for current smoking among hypertensive patients, and increasing age (OR=0.723, 95%CI: 0.642-0.815) and high exercise frequency (OR=0.881, 95%CI: 0.817-0.950) as barrier factors, while male ( OR=7.309, 95%CI: 3.304-16.165), increasing age ( OR=1.381, 95%CI: 1.120-1.703 ), unmarried ( OR=1.819, 95%CI: 1.329-2.490 ), divorced ( OR=7.837, 95%CI: 1.254-48.975 ), retired ( OR=1.545, 95%CI: 1.095-2.180 ), unemployed (OR=1.801, 95%CI: 1.057-3.066), and high exercise frequency ( OR=1.221, 95%CI: 1.096-1.360 ) were identified as facilitating factors for smoking cessation among hypertensive patients and widowed ( OR=0.285, 95%CI: 0.089-0.906 ), high educational level ( OR=0.766, 95%CI: 0.619-0.949 ), and drinking ( OR=0.488, 95%CI: 0.368-0.647 ) as barrier factors.
Conclusions
The prevalence of smoking is lower, and the prevalence of smoking cessation is higher among hypertensive patients than among general populations in Nanshan District. Young and middle-aged, employed, widowed men with a high educational level are key populations for tobacco control, and alcohol consumption control and intensified exercises are important measures to reduce the prevalence of smoking and improve the prevalence of smoking cessation.

Objective:
To investigate the trend in incidence of stroke in Nanshan District, Shenzhen City from 2010 to 2021, so as to provide the evidence for formulating the integrated strategy for stroke control.
Methods:
The data of stroke morbidity in Nanshan District from 2010 to 2021 were collected through Shenzhen Chronic Disease Prevention and Control Management System. The incidence of stroke was calculated, and standardized by the population of the Chinese Sixth National Census in 2010. The trends in stroke incidence were evaluated in Nanshan District from 2010 to 2021 using annual percent change (APC) and average annual percent change (AAPC), and gender-, age- and subtype-specific incidence of stroke was descriptively analyzed.
Results:
A total of 30 377 cases with stroke were reported in Nanshan District from 2010 to 2021, with a crude incidence rate of 190.45/105 and a standardized incidence rate of 405.65/105. The crude incidence rate of stroke appeared a tendency towards a rise in Nanshan District from 2010 to 2021 (APC=5.38%, t=4.678, P=0.001), and a higher crude incidence rate of stroke was seen among men than among women (227.57/105 vs. 148.40/105; χ2=1 309.580, P<0.001). The incidence of stroke appeared a tendency towards a rise with age (χ2trend =435.717, P<0.001), and there was a tendency towards a rise in stroke incidence among residents under 40 years of age (APC=2.89%, t=2.538, P=0.029). The crude incidence of ischemic stroke was 151.24/105, which was higher than that of hemorrhagic stroke (39.21/105) (χ2=10 521.000, P<0.001).
Conclusions
The incidence of stroke appeared a tendency towards a rise in Nanshan District from 2010 to 2021, with ischemic stroke as the predominant subtype of stroke. Males and middle-aged and elderly residents should be given a high priority for stroke prevention and treatment.

Objective:
To analyze the influencing factors for hospitalization costs among stroke patients with different subtypes, so as to provide the reference for reducing the economic burden of patients.
Methods:
Data of patients with hemorrhagic or ischemic stroke who were discharged from hospitals in Nanshan District, Shenzhen City from January 1, 2016 to December 31, 2021 were collected through Hospital Information System. Hospitalization costs were analyzed between hemorrhagic and ischemic stroke patients, and factors affecting hospitalization costs among stroke patients with different subtypes were identified using a structural equation model.
Results:
A total of 10 298 patients with stroke were recruited, including 2 820 patients with hemorrhagic stroke (27.38%) and 7 478 patients with ischemic stroke (72.62%). The patients with hemorrhagic stroke had a median duration of hospital stay of 19.00 (interquartile range, 18.00) d, and a median hospitalization cost of 26 759.48 (interquartile range, 51 000.87) Yuan. The patients with ischemic stroke had a median duration of hospital stay of 12.00 (interquartile range, 10.00) d, and a median hospitalization cost of 12 199.87 (interquartile range, 13 290.20) Yuan. Structural equation model analysis showed that department of hospitalization, discharge status, ways of leaving hospital, surgery and hypertension had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among hemorrhagic stroke patients, and duration of hospital stay had the highest total effect (0.684), followed by surgery (0.632). Employment status, admission route, department of hospitalization, ways of leaving hospital, payment mode, surgery and dyslipidemia had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among ischemic stroke patients, and duration of hospital stay (0.746), surgery (0.424) and department of hospitalization (0.151) ranked the top three in total effects.
Conclusion
The hospitalization cost is relatively high among stroke patients in Nanshan District, and duration of hospital stay and surgery have great influence on hospitalization costs among stroke patients with different subtypes.
