Abstract
BACKGROUND We previously reported that REBACIN effectively eliminates persistent high-risk human papillomavirus (hrHPV) infection. Here, we conducted a prospective multicenter cohort study to evaluate the safety and effectiveness of REBACIN, taking into account factors such as specific hrHPV subtype and patient's age. METHODS According to inclusion/exclusion criteria and participant willingness, 3252 patients were divided into REBACIN group while 249 patients into control group. Patients in REBACIN group received one course treatment of intravaginal administration of REBACIN while no treatment in control group. After drug withdrawal, participants in both groups were followed up. RESULTS The clearance rate of persistent hrHPV infection in REBACIN group was 60.64%, compared to 20.08% in control group. Specifically, the clearance rates for single-type infection of HPV16 or HPV18 were 70.62% and 69.23%, respectively, which was higher than that of HPV52 (59.04%) or HPV58 (62.64%). In addition, the single, double, and triple/triple+ infections had a clearance rate of 65.70%, 53.31%, and 38.30%, respectively. Moreover, 1635 patients under 40 years old had a clearance rate of 65.14%, while it was 55.08% for 1447 patients over 40 years old. No serious adverse effects were found. CONCLUSION This study confirmed that REBACIN can effectively and safely eliminate persistent hrHPV infection, which the clearance rate of HPV16/18 is higher than that of HPV52/58, the clearance rate of single-type infection is higher than that of multiple-type infections, and the clearance rate in young patients is higher than that in elder patients, providing a guidance for REBACIN application in clearing hrHPV persistent infection in real-world settings.

Abstract
BACKGROUND The digital divide between urban and rural adolescents is widening. Many existing studies have found an association between internet use and adolescent mental health, but few use longitudinal data to focus on rural adolescents. We aimed to identify the causal relationships between internet use time and mental health in Chinese rural adolescents. METHODS Using a sample of 3694 participants (aged 10-19) from the 2018-2020 China Family Panel Survey (CFPS). Fixed effects model, mediating effect model and instrumental variables method was used to evaluate the causal relationships between internet use time and mental health. RESULTS We find that more time spent on the internet has a significant negative effect on participants' mental health. This negative impact is stronger in female and senior students groups. Mediating effects analysis suggests that more time spent on the internet increase risk of mental health problems by reducing sleep duration and parent-adolescent communication. Further analysis find that online learning and online shopping is associated with higher depression scores, while online entertainment with lower depression scores. LIMITATIONS The data do not investigate the specific time spent on internet activities (e.g., learning, shopping, and entertainment), and the long-term impacts of internet use time and mental health have not been tested. CONCLUSIONS Internet use time has a significant negative impact on mental health by crowding out sleep duration and parent-adolescent communication. The results provide an empirical reference for the prevention and intervention of mental disorders in adolescents.

Abstract
SIRT3 is a mitochondrial deacetylation protein that can promote the invasion and migration of cancer cells. We explored the effects of SIRT3 regulation of the AMPK/PPAR signaling pathway on triglycerides and the invasion and metastasis of cervical cancer cells. Immunohistochemical methods were used to detect SIRT3. The expression of AMPK and PPAR proteins in different cervical lesions was analyzed in combination with clinicopathological parameters. qRT-PCR and western blotting were used to determine the expression levels of SIRT3 in the C33a and SiHa cervical cancer cell lines. To observe the effects of altering SIRT3 levels by lentivirus transfection and the consequent changes in AMPK and PPAR protein expression, oil red O staining was used to determine intracellular triglycerides, and scratch assays and Transwell chamber experiments were performed to evaluate cervical cancer cell migration and invasion. Our data indicate that SIRT3, AMPK, and PPAR protein expression levels show an increasing trend with cervical lesion severity and are related to the degree of lymph node metastasis and differentiation; moreover, increased expression of SIRT3 can promote the expression of AMPK and PPAR proteins, is beneficial to the formation of intracellular neutral fat, and enhances the ability of cells to metastasize and invade. Our results suggest that SIRT3 activates AMPK/PPAR signaling pathways involved in cancer lipid metabolism and promotes metastasis and cell invasion.

Abstract
Objective: To discuss the effects of transjugular intrahepatic portosystemic shunt (TIPS) procedure on hemodynamics in cirrhotic patients. Methods: A total of 23 cirrhotic patients for TIPS insertion were enrolled from January 2018 to October 2018. Serum N-terminal pro-B-type natriuretic peptide (NT-proBNP), transthoracic echocardiography and non-invasive cardiac output measurement based on impedance cardiogram were carried out before and 24h, 1 month, 6 months after TIPS in order to observe cardiac function and hemodynamic changes after TIPS. Results: Significant increases in right atrial area [(17.2±4.0) cm(2) vs. (15.0±3.4) cm(2), P<0.05], right ventricular area [(15.1±3.8) cm(2) vs. (13.7±3.5) cm(2), P<0.05] and left ventricular volume [(97.4±21.5) ml vs. (91.1±22.7) ml, P<0.05] were observed 24 h after TIPS. These changes were accompanied with significant reduction in collapsible index of inferior vena cava [(20.7± 8.1)% vs. (28.6±11.3)%, P<0.01] and elevation in pulmonary arterial systolic pressure [(36.0±8.4) mmHg (1 mmHg=0.133 kPa) vs. (31.8±5.4) mmHg, P<0.01]. There also existed significantly elevated serum NT-proBNP [(551.2±325.1) ng/L vs. (124.2±94.4) ng/L, P<0.01], cardiac output [(5.82±0.96) L/min vs. (5.12±1.28) L/min, P<0.01], cardiac index [(3.47±0.64) L·min(-1)·m(-2) vs. (3.05±0.78) L·min(-1)·m(-2), P<0.01], early diastolic filling rate [(59.0±14.3)% vs. (54.5±11.0)%, P<0.05], and reduced systemic vascular resistance index (SVRi) [(1 798.4±357.3) dyne·s·cm(-5)·m(-2) vs. (2 195.7±508.7) dyne·s·cm(-5)·m(-2), P<0.01] 24 h after TIPS. At the end of 6-month follow-up, all these parameters, but not SVRi, returned towards baseline values. Moreover, peak early to late diastolic tissue velocity ratio at the level of lateral mitral annulus (E'/A') was significantly higher at the end of 6-month follow-up than that at baseline (1.06±0.32 vs. 0.90±0.45, P<0.05). Neither the right ventricular fractional area changes nor the left ventricular ejection fractions during the follow-up period were different from those at baseline (P>0.05). Conclusion: Cirrhotic patients who had no cardiovascular pathologies had adequate adaptation and good compensation ability to reach a new hemodynamic homeostasis for the increased volume load after TIPS insertion.

Abstract
In the perspective of promoting the strategic goal of healthy China, this study reviewed the informatization process of disease prevention and control in China and clarified the important role of national health information in chronic disease information surveillance throughout the life cycle. Guided by goals, needs, and problems, it is proposed that when basic personal electronic health record (EHR) are not well-established, personal electronic disease record (EDR) could be established to support business collaboration. Driven by the construction of national health informatization, this study proposed the relationship between the national health and chronic disease prevention and control coverage and described the architecture design of an integrated and restructured national disease prevention and control information system and its life-cycle monitoring and information management model for chronic disease health events.

Abstract
Objective: To observe and compare the effects of two standards on the overweight trend in urban Shanghai infants and young children. Methods: A cluster randomized controlled trial was conducted in 19 communities in two districts of Shanghai, and the subjects (n=15 019) were divided into S-group and W-group by sealed envelope randomization. The subjects were newborns born between November 2013 and December 2014. The 2005 Shanghai growth standard was applied in the S-group and the 2006 WHO growth standard was used in the W-group. At each follow-up time point age of 1, 2, 4, 6, 9, 12 and 18 months, the outpatient physician assessed the length and weight of the infants according to the standard adopted by each group and provided feeding guidance. The weight-for-age Z scores (WAZ), length-for-age Z scores (LAZ) and weight-for-length Z scores (WLZ) were calculated according to the WHO standard. Weight, length, WAZ, LAZ, WLZ and overweight ratio (WLZ≥2) were compared between the two groups using t test, Wilcoxon test and χ(2) test. Results: A total of 6 509 infants (3 391 were boys, 3 118 were girls) were in the W-group, and 8 510 infants (4 374 were boys, 4 136 were girls) were in the S-group. Among the boys, the weight values at the age of 4, 6, 9, 12, 18 months in the W-group were all lower than those in the S-group ((7.5±0.8) vs. (7.7±0.8) kg, (8.6±0.8) vs. (8.7±0.8) kg, (9.6±0.9) vs. (9.7±0.9) kg, (10.4±1.0) vs. (10.5±1.0) kg, (11.5±1.1) vs.(11.7±1.1) kg; t=4.329, 2.422, 3.739, 2.451, 2.736; P<0.01, 0.015,<0.01, 0.014, 0.009). The length had no significant difference between two groups at all months of age(all P>0.05). The overweight ratio in the W-group was lower than that in the S-group at the age of 9, 12, 18 months(3.3% (71/2 170) vs. 4.9% (143/2 927), 2.5% (51/2 037) vs. 4.5% (126/2 818), 0.8% (7/832) vs. 3.1% (39/1 266); χ(2)=6.520, 14.209, 12.350; P=0.011,<0.01,<0.01).Among the girls, except at the age of 2 months (W-group (5.6±0.6) vs. S-group (5.7±0.6), t=2.935, P=0.003), weight values had no significant difference between the two groups at other age months (all P>0.05).The length in the W-group was higher than that in the S-group at 12 and 18 months of age ((75.6±2.4) vs.(75.5±2.3)cm, (82.4±2.9) vs.(82.2±2.7) cm; t=2.351, 2.197; P=0.019, 0.028). The ratio of overweight in the W-group was lower than that of S-group at the age of 12 and 18 months (1.8% (33/1 871) vs.3.0% (80/2 658), 0.6% (5/790) vs.1.7% (20/1 178); χ(2)=6.764,4.276; P=0.009, 0.039). Conclusions: The application of WHO growth standard can help to reduce the weight gain rate of boys, promote the linear growth of girls, and thus alleviate the overweight trend of infants within 18 months. It suggested that 2006 WHO growth standard should be applied to infants within 1 year of age in Shanghai.

Abstract
Objective: To account the direct cost of uterine cervix carcinoma treatment in China and to explore the related factors which influence the direct financial burden of the disease. Methods: Data was collected through the medical record system and telephone interviews in 14 county-level hospitals and 9 provincial and municipal hospitals from 14 provinces/municipalities enrolled in the Chinese National Health Industry Research Project in 2015. The direct financial burden of uterine cervix carcinoma treatment consisted of the direct medical cost and the direct non-medical cost of treatment in different pathological cervical cancer stages and precancerous lesions. Multiple liner regression method was used to analyze the factors affecting the costs. Results: The age of the 3 246 patients was (46.40±10.43) years, including 2 423 patients from provincial and municipal hospitals and 823 patients from county-level hospitals. The direct financial burden for one patient of pathological uterine cervix carcinoma stage or precancerous lesion ranged from 10 156.3 yuan to 75 716.4 yuan in provincial and municipal hospitals, and for patients from county-level hospitals, the cost was between 4 927.9 yuan and 47 524.8 yuan per person. There was a wide gap between the direct financial burden of patients in different disease stages. The direct financial burden of patients with precancerous lesions ranged from 4 927.9 yuan per person to 11 243.0 yuan per person, as for patients of pathological uterine cervix carcinoma stages, the direct financial burden was between 29 274.6 yuan and 75 716.4 yuan per person. The factors which influence direct financial burden would include: the levels of the hospital, pathological period, medicare reimbursement, days of treatment, and the methods of treatment (P<0.001). Conclusion: The direct financial burden of diseases in patients with pathological uterine cervix carcinoma stage or precancerous lesion differed in different levels of hospital and pathological periods. In addition, medicare reimbursement, days of treatment, and the methods of treatment all had impact on it.

Abstract
Overexpression of the prolyl isomerase PIN1 is involved in tumorigenesis, but the role of PIN1 in cervical cancer is unclear. In this study, we examined PIN1 protein expression by immunohistochemistry in 221 paraffin-embedded samples from cervical cancer patients, cervical intraepithelial neoplasia patients, and control tissues, and found that high expression of PIN1 was significantly associated with lymph node metastasis (P=0.002), advanced stage according to the International Federation of Gynecology and Obstetrics guidelines (P=0.026). When endogenous PIN1 expression was knocked down using siRNA, cell proliferation, colony formation, migration, and invasion were inhibited in the SiHa cervical cancer cell line. Additionally, PIN1 knockdown increased E-cadherin and β-catenin expression, and decreased expression of N-cadherin and Vimentin, suggesting that PIN1 can promote epithelial-mesenchymal transition (EMT). These results indicate that the Overexpression of the prolyl isomerase PIN1 in cervical cancer indicates tumor-Promotive properties of PIN1 that may be a marker of poor prognosis in cervical cancer patients, and the molecular determinants of epithelial polarity which have tumorigenesis enhancing impact, might through EMT.

Abstract
OBJECTIVES To explore the relationship between the change rules of volatile organic compounds (VOCs) in rat muscle and postmortem interval (PMI). METHODS A total of 120 healthy rats were divided randomly into 12 groups (10 for each group). After the rats were sacrificed by cervical dislocation, the bodies were kept at (25±1) ℃. Rat muscle samples were separately obtained at 12 PMI points, including 0, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 d. The VOCs in rat muscles were collected, detected and analyzed by headspace solid-phase microextraction (HS-SPME) coupled to gas chromatography-mass spectrometer (GC-MS). RESULTS In total, 15 species of VOCs were identified, including 9 aromatic compounds, 3 sulfur compounds, 2 aliphatic acids and 1 heterocyclic compound. The species of VOCs increased with PMI: no species were detected within 1 day, 3 species were detected on day 2, 9 on day 3, 11 on day 4, 14 from day 5 to 7, and 15 from day 8 to 10. Total peak area of 15 species of VOCs was significantly correlated to PMI (adjusted R²=0.15-0.96): the regression function was y=-17.05 x²+ 164.36 x-246.36 (adjusted R²=0.96) from day 2 to 5, and y=2.24 x+101.13 (adjusted R²=0.97) from day 6 to 10. CONCLUSIONS The change rules of VOCs in rat muscle are helpful for PMI estimation.

Abstract
OBJECTIVE To describe the flow of tuberculosis(TB)cases for medical care in China in 2014. METHODS The analysis and visualization of reported flow of TB cases were conducted with software R to indicate the case distribution/flow and the levels of hospital where TB cases sought medical care in different provinces. RESULTS In a province, the TB cases mainly flowed to the province capital, but the inter-provincial flow was mainly to neighbor provinces and from central or western provinces to eastern provinces(municipality), such as Beijing, Shanghai and Guangdong. The grade Ⅲ(A)hospitals were the choice of most TB cases seeking medical care in other provinces. CONCLUSION The epidemic situation of TB in China is still serious, and the flow of TB cases would facilitate the spread of the disease. It is necessary to strengthen the research on influence of TB case flow for seeking medical care on the spread of TB to provide evidence for better TB prevention and control.

Abstract
Nuclear factor erythroid-2-related factor 2 (NFE2L2) is a transcription factor associated with resistance to chemotherapy and increased tumor growth. NRF2 is repressed by the inhibitor Keap1. The Keap1-NRF2 pathway is dysfunctional in multiple tumor types. Among Uighur women, the incidence of cervical squamous cell carcinoma (CSCC) and cervical intraepithelial neoplasia (CIN) was associated with elevated nuclear expression of NRF2 and decreased cytoplasmic expression of Keap1. Up-regulation of nuclear NRF2 was significantly associated with reduced cytoplasmic Keap1 expression. NRF2 positivity and Keap1 negativity were frequently associated with more advanced tumors (i.e., higher histological grade, lymph node involvement, and higher tumor stages) (p<0.05 for all). Methylated CpG islands in the Keap1 gene promoter in cervical cancer tissue were identified using MassARRAY. Moreover, promoter hypermethylation of this gene was significantly associated with decreased protein expression and increased nuclear NRF2 expression in cervical cancer tissues. Overexpression and knockdown of NRF2 in CSCC cell lines showed that NRF2 promotes proliferation, inhibits apoptosis, and enhances migration and invasion. These studies support the concept that epigenetic changes regulate expression of Keap1 in cervical cancer tissues. The association of NRF2 expression with aggressive tumor behavior suggests that NRF2 may be a marker of poor prognosis in patients with cervical cancer.

Abstract
(1)H nuclear magnetic resonance (NMR)-based metabonomics has been used to characterize the metabolic profiles of cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC). Principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis (OPLS-DA) were used to model the systematic variation related to patients with CIN or CSCC with healthy controls. Potential metabolic biomarkers were identified using database comparisons, and the one-way analysis of variance (ANOVA) test was used to examine the significance of the metabolites. Compared with plasma obtained from the healthy controls, plasma from patients with CIN had higher levels of very-low density lipoprotein (VLDL), acetone, unsaturated lipid and carnitine, together with lower levels of creatine, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine, glycine, acetylcysteine, myo-inositol, choline and glycoprotein. Plasma from patients with CSCC had higher levels of acetate and formate, together with lower levels of creatine, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine and tyrosine compared with the plasma of the healthy controls. In addition, compared with the plasma of patients with CIN, the plasma of CSCC patients had higher levels of acetate, formate, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine, tyrosine, acetylcysteine, myo-inositol, glycoprotein, α-glucose and β-glucose, together with lower levels of acetone, unsaturated lipid and carnitine. Moreover, the profiles showed high feasibility and specificity by statistical analysis with OPLS-DA compared to the Thinprep cytology test (TCT) by setting the histopathological outcome as standard. The metabolic profile obtained for cervical cancer is significant, even for the precancerous disease. This suggests a systemic metabolic response to cancer, which may be used to identify potential early diagnostic biomarkers of the cancer and to establish clinical diagnostic methods.

Abstract
OBJECTIVE To investigate the reason why the incidence of endometriosis (EM) is lower in the Uygur women than in the Han women. METHODS Eutopic and ectopic endometrium samples were obtained by operation and biopsy from 26 EM patients, 10 Uygur women and 16 Han women and analyzed with a gene expression microarray containing the cDNAs of 22 000 human genes. Twenty-two women, 10 Uygur and 12 Han, were used as controls. RESULTS Eleven differentially expressed genes, 7 up-regulated and 6 down-regulated, were screened out from the eutopic endometrium of the Uygur women with EM. 58 differential expressed genes were screened out from the in eutopic endometrium of the Han women with EM, 53 being up-regulated and 5 down-regulated. Five genes were screened out in both groups, 3 being up-regulated and 2 down-regulated. CONCLUSION The number of differentially expressed genes of the Uygur women with EM is lower than that of the Han women with EM, which may be the cause of relative low incidence of EM among Uygur women.

Abstract
Alternariol caused DNA single-strand breakage. Conversion of the closed circular double-stranded supercoiled DNA (pBR 322) to the nicked circular form and linear form was used to investigate the effect of extracts of some Chinese medical herbs on DNA nicking induced by alternariol. Some substances in the extracts of Rhizoma polygonati (RP) and Fructus lycii (FL) were shown to protect DNA from the attack by alternariol. Some substance in the RP may bind to plasmid DNA, and this binding reduces the electrophoretic mobility of DNA. These results indicate that substances from FL and RP may be used as DNA protectors. It is possible that they play an important role in preventing cancer.

Abstract
The bovine papillomaviruses (BPVs) types 1, 2, and 5 cause fibropapillomas whereas BPVs types 3, 4, and 6 cause true papillomas. A novel method of heteroduplex mapping at low stringency of hybridisation has identified the position and relative orientation of distantly related sequences in the genomes of these viruses. The genomes of BPV-1 and BPV-2 are closely related but both show a high degree of sequence divergence from the BPV-5 genome. A 1.25-kb sequence adjacent to the unique BamHI site of the BPV-5 genome hybridised to BPV-1 and to the equivalent region of BPV-2. The hybridising sequence in the BPV-1 genome mapped to the C-terminal region of the E1 open reading frame (ORF) and the N-terminal region of the E2 ORF. The BPV-3, BPV-4, and BPV-6 genomes show moderate homology to each other but minimal homology to the fibropapillomavirus genomes. Low-stringency heteroduplex mapping revealed that overlapping sequences in the BPV-1 E1 and L1 ORFs (or the equivalent regions in BPV-2) hybridised to sequences in BPV-3, BPV-4, and BPV-6. Hybrid regions were less than 1 kb long and were sometimes interrupted by short nonhybridising segments. The hybridising sequences in BPV-3 and BPV-4 are positioned in a way that parallels the spacing of the E1 and L1 ORFs in BPV-1. These data suggest that the bovine fibropapilloma viruses and true papilloma viruses share a similar genomic organization, but have undergone extensive sequence divergence.
