RESUMO
Objectives@#Fitting and forecasting the trend of COVID-19 epidemics.@*Methods@#Based on SEIR dynamic model, considering the COVID-19 transmission mechanism, infection spectrum and prevention and control procedures, we developed SEIR+ CAQ dynamic model to fit the frequencies of laboratory confirmed cases obtained from the government official websites. The data from January 20, 2020 to February 7, 2020 were used to fit the model, while the left data between February 8-12 were used to evaluate the quality of forecasting.@*Results@#According to the cumulative number of confirmed cases between January 29 to February 7, the fitting bias of SEIR+ CAQ model for overall China (except for cases of Hubei province), Hubei province (except for cases of Wuhan city) and Wuhan city was less than 5%. For the data of subsequent 5 days between February 8 to 12, which were not included in the model fitting, the prediction biases were less than 10%. Regardless of the cases diagnosed by clinical examines, the numbers of daily emerging cases of China (Hubei province not included), Hubei Province (Wuhan city not included) and Wuhan city reached the peak in the early February. Under the current strength of prevention and control, the total number of laboratory- confirmed cases in overall China will reach 80 417 till February 29, 2020, respectively.@*Conclusions@#The proposed SEIR+ CAQ dynamic model fits and forecasts the trend of novel coronavirus pneumonia well and provides evidence for decision making.
RESUMO
Objective@#The number of confirmed and suspected cases of the COVID-19 in Hubei province is still increasing. However, the estimations of the basic reproduction number of COVID-19 varied greatly across studies. The objectives of this study are 1) to estimate the basic reproduction number (R0) of COVID-19 reflecting the infectiousness of the virus and 2) to assess the effectiveness of a range of controlling intervention.@*Method@#The reported number of daily confirmed cases from January 17 to February 8, 2020 in Hubei province were collected and used for model fit. Four methods, the exponential growth (EG), maximum likelihood estimation (ML), sequential Bayesian method (SB) and time dependent reproduction numbers (TD), were applied to estimate the R0.@*Result@#Among the four methods, the EG method fitted the data best. The estimated R0 was 3.49 (95% CI: 3.42-3.58) by using EG method. The R0 was estimated to be 2.95 (95%CI: 2.86-3.03) after taking control measures.@*Conclusion@#In the early stage of the epidemic, it is appropriate to estimate R0 using the EG method. Meanwhile, timely and effective control measures were warranted to further reduce the spread of COVID-19.

RESUMO
Objective@#To evaluate the effect of the "Interner Plus-based AIDS Comprehensive Prevention Service System" among MSM in Guangzhou, during 2010-2017, using a dynamic compartmental model.@*Methods@#A dynamic compartmental model was developed to describe the HIV situation among MSM in Guangzhou. This model was parameterized on data from published literature or surveillance programs from the Guangzhou CDC. The Matlab 7.0 software was used for coding and analysis on collected data. HIV prevalence was analyzed among MSM under the status quo data and estimated the impact by the "Internet Plus" AIDS prevention services project.@*Results@#HIV prevalence would have increased to 22.75% in 2017, and the total number of new HIV infections would have been 11 038, from 2010 to 2017, using the data status quo. Under the Guangzhou "Internet Plus" AIDS prevention services project, the prevalence of HIV among MSM from 2010 to 2017 was estimated to be 8.44%, 9.68%, 10.65%, 11.34%, 11.73%, 11.83%, 11.71% and 11.43% in Guangzhou, which were similar to the surveillance data. The total number of new infections in the past 8 years under the "Internet Plus" scenario was estimated to be 4 009. The "Internet Plus" program would have prevented 7 029 (63.68%) new infections during 2010-2017 as compared to the number, status quo.@*Conclusions@#The fitting result of dynamic compartmental model seemed more reasonable, which was applicable to predict HIV epidemic among MSM in Guangzhou, suggesting that the increase of HIV prevalence had been curbed since the "Internet Plus" project which was launched in 2010, and the "Interner Plus-based AIDS Comprehensive Prevention Service System" had achieved the purpose as planned, epidemiologically.
RESUMO
Objective@#To evaluate the burden and to describe the characteristics of spatial distribution caused by malignant tumors among different administrative areas in Guangzhou from 2010- 2013.@*Methods@#Based on data from the Cancer Registry system and population in Guangzhou in 2010- 2013, disability-adjusted life year (DALY) was assessed on the disease burden of cancer, in accordance with the method used in the Global Burden of Disease study.@*Results@#The crude incidence rates of cancer appeared as 256.22/105 in 2010-2011 and 270.04/105 in 2012-2013, with the crude mortality rates as 143.17/105 and 148.01/105, respectively, in Guangzhou. Cancers caused 606 238.95 DALYs in 2010-2011 and 623 763.80 DALYs in 2012-2013 for both sexes and 37.63 and 37.81 person year per 1 000 persons, with the standardized DALY rates as 34.51‰, 34.00‰ respectively. Three administrative districts (Yuexiu, Haizhu and Liwan) were with the largest disease burden of cancers that accounted for 45% of the DALYs for the whole Conghua district, with liver cancer was the leading cancer on DALYs, and tracheal, bronchus and lung cancer ranked the first in the other districts.@*Conclusions@#In Guangzhou, disease burden caused by cancers was both prominently seen in the newly developed urban area and the old districts. It remains an arduous task to continue programs on control and prevention of cancers in this city.
RESUMO
Objective@#To estimate the health-related quality of life (HRQOL) and health-adjusted life expectancy (HALE) which were associated with chronic non-communicable diseases (NCDs) in people from Guangdong province of China.@*Methods@#Data on both NCDs prevalence and EuroQol-5 Dimensions-3 Levels measured HRQOL were gathered from the Fifth National Health Survey in Guangdong province, 2013. Logistic regression model and multiple linear regression model were employed to explore the impact of NCDs on HRQOL. Life expectancy (LE) and HALE were used to evaluate the comprehensive impact of chronic diseases on population health.@*Results@#A total of 68 550 inhabitants were included in the analysis. Graded logistic regression showed that the impact of chronic diseases on all dimensions of quality of life was statistically significant after adjusting for social demographic characteristics. The greatest health impact was on the pain/discomfort health dimension [OR=4.48 (95%CI:4.20-4.77)], followed by anxiety/depression[OR=3.95 (95%CI: 3.62- 4.31)], daily activities [OR=3.69 (95%CI: 3.37-4.04)], mobility [OR=3.63 (95%CI: 3.34-3.94)]and ability on self-care [OR=3.30 (95%CI: 2.98-3.66)]. Losses of LE and HALE caused by NCDs were 12.7 and 14.6 years respectively while the overall expected gain was 3.8 years in HALE, when NCDs were taken away.@*Conclusions@#Our data showed that NCDs had shortened the healthy life span of patients through reducing the HRQOL and also causing heavy disease burden on both patients with NCDs and the communities. Health-care related policies on NCDs need to be developed, for the elderly, in particular.
RESUMO
Objective: To establish a dynamic compartmental model to predict the impact of HIV testing and treatment and pre-exposure prophylaxis (PrEP) on the annual incidence of HIV infection in men who have sex with men (MSM) in China from 2018 to 2037. Methods: A dynamic compartmental model was developed to describe the HIV epidemic in MSM in China. The model was parameterized using data from the literature available. We used MATLAB 7.0 software for data simulation and graphics rendering. We analyzed HIV transmission among MSM and estimated the impact of expanded HIV testing and treatment and PrEP on HIV elimination in MSM. Results: Under the current policy, the number of new HIV infections would reach 770 000, the infection rate would reach 11.1% and the incidence rate would reach 0.72/100 person years in MSM in the next 20 years. Under the 90%-90%-90% goal, 440 000 new infections (57.7%) would be reduced, the HIV infection rate would decline to 5.7% and the incidence rate would decline to 0.24/100 person years in the next 20 years, but it is still unlikely to achieve the goal of HIV elimination. With 100% PrEP compliance, the required PrEP coverage rates for achieving HIV elimination in the next 10, 15 and 20 years would be 65%, 32% and 19%, respectively. Conclusion: It is necessary to strengthen the comprehensive intervention in MSM, continue to expand HIV testing and treatment, and improve PrEP adherence and coverage to further control and eliminate the epidemic of HIV/AIDS in MSM.

Objective To acknowledge the quality of life (QOL) in patients after lung transplantation and to explore related factors. Methods A cross- sectional study design and a convenience sampling were performed in this research. Totally 30 patients after lung transplantation were investigated. The questionnaires which used to explore the quality of life were Short Form 36 Health Survey Questionnaires (SF-36) and Revised Airways Questionnaires 20 (AQ20-R). Related state were surveyed by questionnaires consisted of demographic questionnaires, Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) and Medical Coping Mode Questionnaires (MCMQ). Statistical analysis was performed by SPSS 20.0 software. Correlation analysis and multivariate analysis were performed using Pearson linear correlation analysis and multi-linear regression. Results The scores among the 8 dimensions of SF-36 were(34.48±16.73)-( 71.63±22.83), lower than those of norms(Z=-9.684--2.817, P<0.05 or 0.01). Somatic pain scored the highest (71.63±22.83), while physiological function scored the lowest (34.48±16.73). The mean score of AQ20-R was 7.93±5.21. The major two problems that manifested QOL were: uncomfortable feeling of lung caused by strong scent, smog or perfume, exhausted feeling after having a cold. The mean scores of SAS and SDS were 44.33±9.33,48.05±9.80, higher than those of norms, which were 33.80 ± 5.90, 41.88 ± 10.57 (t=6.1833, 3.4458, P < 0.01). The scores among the 3 dimensions of MCMQ were 8.93 ± 2.08, 16.10 ± 2.28, 3.63 ± 1.33 and the differences were significant in 3 dimensions compared with those norms, which were 19.48±3.81, 14.44±2.97, 8.81±3.17(t=-27.7281, 3.9885,-21.3878, P<0.01). Conclusions In SF-36, role-physical of patients after lung transplantation was the worst dimension, while bodily pain was the best dimension of QOL. The QOL of patients after lung transplantation were almost worse than normal people. The related factors of QOL in patients after lung transplantation maybe:anxiety, depression and medical coping style.
RESUMO
Objective To explore the effect of psychological stress and salivary cortisol on the pregnancy outcome of pregnant women with preterm birth. Methods From January to September 2016, the convenience sampling method was adopted to select 138 pregnant woman with preterm preterm delivery of preterm preterm births in a class of grade 3 obstetrics and gynecology specialized hospitals. Among them, there were 86 pregnant women with preterm birth and 52 with full-term birth. The perceived stress scale ( PSS) combined with saliva cortisol testing to assess subjective and objective psychological stress of pregnant women, using multiple linear regression analysis the relationship of psychological pressure,salivary cortisol and preterm birth. Results The PSS score of 138 prenant woman was 21.5±8.1 with middle-high level. The PSS score of 86 pregnant women with preterm birth were higher those of 52 with full-term birth. The salivary cortisol levels of 8:00am, 16:00pm and 23:00pm in 86 pregnant women with preterm birth were respectively significantly higher than those of 52 with full-term birth (P<0.001). Multiple linear regression analysis showed that high PSS score and short pregnant weeks with preterm birth were also risk factors for premature birth (all P<0.05). Conclusions High levels of psychological stress and short pregnant weeks are risk factors for premature birth. Health care workers can reduce the incidence of preterm labor by improving the mental state of pregnant women.

Objective To elucidate the association of interleukin (IL)-17F A7488G (p.His161Arg) polymorphism with gastric cancer susceptibility,clinicopathological features and survival.Methods DNA from 927 unrelated patients with gastric cancer and 777 age and gendermatched healthy controls was typed for IL-17F A7488G polymorphism by polymerase chain reactionrestriction fragment length polymorphism.Logistic regression analyses and Cox proportional hazards analyses were used to evaluate the associations between polymorphisms and gastric cancer susceptibility,clinicopathological features and survival.Results There was significant difference between healthy controls and patients with gastric cancer with respect to frequencies of IL-17FA7488G genotypes (X2= 16.55,P<0.01).After adjusted for age and gender,IL-17F A7488G GA and GG genotypes were associated with an increased risk of gastric cancer compared with the AA genotype (OR=1.51;95% CI:1.22-1.87 for GA;OR=1.61,95% CI:1.03-2.51 for GG).In comparison with AA genotype carriers,the risk of gastric cancer increased in those with GA or GG genotypes (OR= 1.53,95 % CI:1.25- 1.87,P<0.01 ).Further stratification analyses indicated that the effect of IL-17F A7488G GA genotype was especially noteworthy in gastric cancer patients of noncardia,intestinal type,poorly and moderately differentiated,and lymph node metastasis.Whereas there was no significant difference in survival among subjects with different polymorphisms of IL-17F A7488G gene (P= 0.534).Conclusions Genetic polymorphism of IL-17F A7488G involves in susceptibility to gastric cancer,which also influences certain subtypes of gastric cancer according to clinicopathological features,however,it is not the independent risk factor for prognosis of gastric cancer patients.
RESUMO
Objective To evaluate the effects of branched-chain amino acids-enriched early parenteral and enteral nutrition on the liver function and serum aminograms in cirrhotic rats after partial hepatectomy. Methods In this prospective randomized controlled study, 24 cirrhotic rats, induced by thioacetamide, were randomized into three groups: enteral nutrition (EN) group, EN + branched-chain amino acid (BCAA) group, and parenteral nutrition (PN) + BCAA group. After receiving partial hepatectomy, rats in all three groups were nutritionally supported with equal amount of calorie and nitrogen contents from the 1st postoperative day ( PO day 1 ) to PO day 5. On PO day 6, parameters including body weight, liver functions, prealbumin, transferring, and serum aminograms were measured or determined, and the level of liver albumin mRNA was detected by reversal transcription-polymerase chain reaction and morphological examinations such as HE staining and immunohistochemical staining, which were assessed by index of Ki67 protein index. Results Body weight was significantly decreased in all three groups on PO day 6 (P ＜0.05 ). Compared with EN + BCAA group, serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase after partial hepatectomy were significantly higher in PN + BCAA group (P ＜0.05 ). Serum alkaline phosphatase level was significantly higher in PN + BCAA group than in EN group ( P ＜0. 05). The level of prealbumin was significantly lower in PN + BCAA group when compared with EN group or EN +BCAA group ( both P ＜ 0. 05 ), although no such significant difference was noted in terms of transferrin ( P ＞0. 05 ). The levels of leucine and isoleucine elevated while those of tyrosine, phenylalanine, arginine and tryptophan declined in PN + BCAA group or EN + BCAA group when compared with EN group ( P ＜ 0. 05 ). Aminograms were not significantly different between EN + BCAA group and PN + BCAA group ( P ＞ 0. 05 ). Levels of total amino acid and aromatic amino acid (AAA) were significantly lower while BCAA and ratio between BCAA and AAA (BCAA/AAA) were significantly higher in PN + BCAA group or EN + BCAA group than in EN group (P ＜ 0. 05 ).Significantly lower level of albumin mRNA and index of Ki67 were observed in PN + BCAA group than in EN group or EN + BCAA group (P ＜ 0.05 ) on PO day 6. Conclusions BCAA-enriched EN or PN reverses amino acid disequilibrium and restores BCAA/AAA in cirrhotic rats after partial hepatectomy. Compared with PN, EN is superior in improving postoperative liver function, promoting protein synthesis, and speed up tissue regeneration in the postoperative liver. However, it still can not restore serum albumin in a short term.
RESUMO
Objective To examine the consistency between asthma children's self-assessment health-related quality of life and their proxies' assessment, to give theoretic basis of clinical treatment for asthma children. Methods Parents and asthma children completed the PedsQLTM 4.0 Generic Core Scales and PedsQLTM 3.0 Asthma Module during an outpatient visit or in the hospital. Wilcoxon signed rank test and ICC were used to compare the difference between asthma children's self-report and their proxies' report. Results The findings indicated that neither the total scores nor domain scores (except physiological domain) between asthma children's self-reports and proxies' reports (parents most of all)showed inconsistency. The value of ICC was not less than 0.7 except physiological dimension and showed consistency. Some different information in several domains was founded by the scores after layered by age. Conclusions There are consistency between children's self assessment of health-related quality of life and their proxies' assessment based upon results of PedsQLTM scale.
