Objective To analyze the intake and changes of food and nutrients in 223 residents of Yangpu District from 2011 to 2015. Methods From the China Nutritional Transition Cohort Study in 2011 and 2015, the data in the study was obtained on Yangpu District′s residents aged 2 and above.A dietary survey was conducted using the 3-day 24-hour dietary recall and condiment weighing method to obtain data on food and nutrients intake per reference man per day and the nutrient source of energy, and to analyze the intake status of different years. Results The intake of vegetables, fruits, livestock and poultry, aquatic products, eggs, milk and dairy products, soybeans and nuts, edible oil and salt per reference man per day was lower in 2015 than in 2011.The insufficient intake proportions of cereals and tubers, vegetables, fruits, aquatic products, eggs, milk and dairy products, soybeans and nuts, and edible oils were 56.0%, 84.0%, 98.2%, 56.0%, 70.2%, 97.8%, 85.3% and 91.1%, respectively, the excessive intake proportion of livestock and poultry meat was 51.6%;the intake of energy, protein, fat and micronutrient per reference man per day in 2015 was lower than in 2011, and the insufficient intake proportion of energy, protein, vitamin A, vitamin B1, vitamin B2, vitamin C, and calcium were 84.0%, 56.4%, 97.3%, 93.8%, 93.3%, 90.2% and 91.6%, respectively.In 2011 and 2015, it was found that residents who had the proportions of energy supply from carbohydrate lower than 50% accounted for 64.6% and 49.8%, those who had the proportions of energy supply from protein higher than 15% accounted for 76.2% and 40.4%, and those who had the proportions of energy supply from fat higher than 30% accounted for 76.7% and 72.9%. Conclusion In 2011-2015, the food and nutrients intakes among community residents in Yangpu District generally decrease, showing the coexistent problems of insufficient and excessive food intake, and the insufficient intake is serious.The insufficient intake of energy, vitamins and calcium is still a severe problem.And the dietary structure is not rational; the proportions of energy supply from three major nutrients are unbalanced.It is suggested that nutrition education for residents should be enhanced.

OBJECTIVETo analyze the drug-sensitivity-related genes to anti-tumor drugs navalbine (NVB) and docetaxel (Doc) in four SCLC and six NSCLC cell lines.

METHODSThe sensitivity of 4 SCLC lines and 6 NSCLC lines to NVB and to Doc was determined with MTT test. The expression of 1291 anti-tumor drug sensitivity-related genes in the 10 cell lines was assayed by cDNA macroarray technique, and cluster analysis was performed to find the relationship between the results obtained by the above mentioned two measurements.

RESULTS(1) The anti-tumor effect of NVB on the 10 cell lines was apparently better than that of Doc. (2) The drug sensitivity-related genes in these 10 cell lines showed a more close positive correlation with Doc than that with NVB, whereas more genes showed negative correlation with NVB than that with Doc. But in 6 NSCLC cell lines, more genes showed the same positive or negative correlation with the two drugs. (3) 51 genes in the 10 cell lines showed correlation with Doc or NVB. 13 of them had negative correlation with Doc, 11 of them showed positive correlation. 24 of them showed negative correlation with NVB, 3 of them showed positive correlation. 67 genes in 6 NSCLC cell lines showed a correlation with sensitivity to Doc or NVB, among them 34 had negative correlation with Doc, 4 had positive correlation. 25 genes had negative correlation with NVB, 4 had positive correlation. (4) Rab 1, Rab 3, Rho B, Rho C, Rac 1, Rac 2, Gho GDI beta, CD44, integrin alpha5, integrin alpha6, integrin beta5, vinculin showed to be cytoskeleton-related genes differently expressing in SCLC or NSCLC cell lines.

CONCLUSIONThere is obvious difference in the drug sensitivity-related genes to NVB or Doc between SCLC and NSCLC cell lines.

Objective To assess the changes in iodine status and dietary iodine intake among Shanghai residents since common salt was iodized 20 years ago.Methods As-CE Catalysis spectrophotometry was used to determinate the urine iodine level in school-age children,pregnant women,wet nurse and adults of Shanghai between 1995 and 2015.B ultrasonic was used to determinate the thyroid volume of school-age children.And then the goiter rate was calculated.Direct titration or arbitration methods were applied to detect the household salt iodine level quantitatively.The survey was conducted by using 3 days 24-hour dietary questionnaire and condiment weighing methods to analyze the level of iodine intake and sources for the cases of all iodized salt consumption and all consumption of non-iodized salt.Results The median urine iodine concentration (UIC) of school age children was 72.3 μg/L in 1995,rose to 214-231 μg/L from 1997-1999,and then became stable between 100 μg/L and 200 μg/L since 2002.The goiter rate was below 5% among children aged 8-10 from 1995-2015 in Shanghai.The median urine iodine of pregnant women was between 126.5 μg/L and 139.8 μg/L.The median UIC of other populations were all between 100 μg/L and 200 μg/L: with adults,lactating women,infants and young children and women of childbearing age,the median urinary iodine was 138.4,123.1-131.1,150.1 and 125.6 μg/L.The qualified iodized salt at household consumption rate was 90% from 2001 to 2009,the percentage declined year by year from 2010.In the cases of all taking iodine salt,the median iodine intake volume for male aged 7-10,11-13,14-18 and over 18 was 200.3,235.5,252.7 and 215.4 μg/L;women aged 7-10,11-13,14-18 and over 18 was 193.0,213.8,208.3 and 186.1 μg/L.The contribution rate of iodine salt in the diet were 51.6%-54.1% and 49.1%-53% in men and women.Kelp,seaweed and fish and shrimp on the contribution of iodine are 7.6%-16.6% and 4.5%-7.4%.Conclusion In the past about 20 years,iodine nutritional status of residents in Shanghai has stabilized totally in a appropriate and safe level.However,the iodine nutrition of pregnant women was insufficient.As iodized salt is the major source of dietary iodine in coastal areas,it is still necessary to continue the policy of universal salt iodized in Shanghai to ensure residents'' needs for iodine and control the risk of iodine deficiency.

Objective:To analyze the risk factors of acute kidney injury (AKI) in hip fracture patients with serious underlying diseases and establish a prediction nomogram.Methods:Clinical information of hip fracture patients admitted to the intensive care unit (ICU) of Beth Israel Deaconess Medical Center (BIDMC) was analyzed using the Medical Information Mart for Intensive Care (MIMIC)-IV. Patient comorbidities, disease scores, vital signs and laboratory tests, surgical modalities, invasive procedures, and drug use were recorded. According to the diagnostic criteria of AKI in the Kidney Disease Improving Global Outcome (KDIGO) guideline, the enrolled patients were randomly divided into training set and validation set. Based on logistic regression analysis, least absolute shrinkage and selection operator (LASSO) logistic regression algorithm was used to analyze the risk factors of AKI after admission, and the corresponding prediction model was calculated.Results:A total of 474 patients were enrolled, including 331 in the training set and 143 in the validation set. According to the diagnostic criteria of AKI of KDIGO guidelines, the patients were divided into AKI group (159 cases) and non-AKI group (172 cases). Univariate analysis showed that age ( t=2.61, P=0.009), coronary heart disease (χ 2=2.08, P=0.038), heart failure (χ 2=2.60, P=0.009), hemoglobin ( t=1.89, P=0.059), platelets ( t=1.81, P=0.070), urea nitrogen ( t=2.83, P=0.005), blood creatinine ( t=3.65, P<0.001), blood sodium ( t=2.55, P=0.011), blood glucose ( t=2.52, P=0.012), anion gap ( t=3.44, P=0.001), diastolic blood pressure ( t=2.72, P=0.007), mean arterial pressure ( t=2.16, P=0.031), SOFA score ( t=3.69, P<0.001), simplified acute physiological function score II (SAPSII) score ( t=2.95, P=0.003), as well as furosemide (χ 2=2.03, P=0.042), vancomycin (χ 2=1.70, P=0.089), vasoactive medications (χ 2=3.74, P<0.001) and use of invasive mechanical ventilation (χ 2=4.81, P<0.001) were risk factors associated with the development of AKI in hip fracture patients. Multivariate logistic regression analysis showed that age ( OR=1.03, P<0.001), coronary heart disease ( OR=2.05, P=0.069), hemoglobin ( OR=0.88, P=0.050), blood creatinine ( OR=1.37, P=0.009), blood sodium ( OR=1.07, P=0.026), anion gap ( OR=1.09, P=0.028) and vasoactive medications ( OR=3.83, P=0.018) and the use of invasive mechanical ventilation ( OR=6.56, P<0.001) were independent predictors of the development of AKI in hip fracture patients with serious underlying diseases. The area under the curve of the nomogram prediction model constructed by the above 8 predictors was 0.789, and the calibration curve of the nomogram was close to the ideal diagonal. Decision curve analysis showed that the net benefit of the model was significant. Conclusion:The incidence of AKI is high in hip fracture patients with serious underlying diseases. Age, coronary heart disease, hemoglobin, serum creatinine, serum sodium, anion gap, vasoactive drugs, and invasive mechanical ventilation can predict the occurrence of AKI to a certain extent. Combined with the risk factors, the construction of the corresponding prediction model can predict and manage the diagnosis and treatment of AKI in patients with hip fracture complicated with severe underlying diseases.

Objective To explore the potential influence of gender on screening value of aldosterone-renin ratio (ARR) for primary aldosteronism (PA).Methods The biochemical parameters were collected of 451 PA patients and 300 essential hypertension (EH) patients who were diagnosed in the General Hospital of PLA from 1992 to 2014. Each group was then divided into two groups by gender. The clinical characteristics were compared and then the receiver operating characteristic curve (ROC) was conducted to evaluate the best cut-off value.Results The plasma aldosterone concentration (PAC), serum sodium and ARR were much higher, but the plasma rennin activity (PRA), serum potassium and BMI were much lower in PA patients than in EH patients (P<0.01), and no significant difference existed between the two groups in age, duration of hypertension and blood pressure. The PRA was obviously lower in males than in females either in PA or in EH patients, but no signicantcant difference existed between males and females in PAC (P>0.05). The best cut-off value of ARR in male PA patients was 19.11, the relevant area under the curve (AUC) was 0.968, the sensitivity and specicantcity was 92.44% and 93.08%, and the Youden index (YI) was 0.86. The best cut-off value of ARR in female PA patients was 27.26, with AUC 0.956, sensitivity 92.07%, specicantcity 90.00% and YI 0.82, respectively. If the cut-off value was set at 27.26 in males, the specicantcity would rise a little, but the sensitivity and YI would sharply decrease. Similarly, the sensitivity would increase a little but the specicantcity and YI would fall substantially if the cut-off value in females was set at 19.11. The best cut-off value of ARR in men was smaller than the ocantcial value recommended by guidelines.Conclusion Gender is an important factor should be considered while ARR is used in PA screening, and the cut-off value of ARR in screening female PA patients should be setting higher.

BACKGROUNDHeterosexual sex has become the dominant transmission route in China. Recently studies reported high heterogeneity in heterosexual transmission risk in resource-limited countries. The aim of this study was to summarize the risk of HIV transmission among Chinese serodiscordant couples.

METHODSA systematic review and meta-analysis of observational studies of heterosexual HIV transmission among serodiscordant couples in China was conducted. Two reviewers conducted a literature search using the China National Knowledge Infrastructure (CNKI), Chinese Medical Current Contents (CMCC), and Medline databases. Pooled transmission estimates per 100 person-years (PY) were calculated using a random-effects model. Meta-regression analysis and subgroup analysis stratified by study design, transmission direction and period of antiretroviral therapy (ART) availability were conducted to assess the factors associated with transmission.

RESULTSEleven eligible studies were identified reporting on 11 984 couples and 405 HIV transmission events. HIV transmission risk from HIV-positive individuals to heterosexual partners was 1.68 (95%CI 0.74 - 2.62) per 100 PY. Study design did not reach statistical significance in meta-regression analysis. The pooled female-to-male transmission estimate was 1.11 (95%CI 0.09 - 2.14) per 100 PY and male-to-female transmission estimate was 1.43 (95%CI 0.19 - 2.68) per 100 PY. The pooled estimate for those before the availability of the Chinese National Free Antiretroviral Therapy Program (2.13 (95%CI 0.00 - 4.63) per 100 PY) was higher than that for those after the implementation of this program (1.44 (95%CI 0.62 - 2.26) per 100 PY).

CONCLUSIONSTransmission estimates in China were lower than other developing countries, but higher than developed countries. Research that better defines HIV secondary transmission rates and the associated behavioral, treatment adherence, and health-related risk factors among heterosexual serodiscordant couples in China is needed.

OBJECTIVETo investigate the early changes of some immunological function of T-cell in chromate workers.

METHODSA total of 115 workers exposed to different levels of soluble chromate were enrolled in exposed group; while 90 non-exposure workers who lived far away from the chromate plant were enrolled as control. The air concentration of soluble chromate was determined by atomic absorption spectrometry. CD3(+), CD3(+)CD4(+), CD3(+)CD8(+) and CD4(+)/CD8(+) of T-cell were determined by flow cytometry analysis.

RESULTSThe individual air chromate concentration in the exposed group was (27.51 +/- 33.25) microg/m(3), and the control group was (0.16 +/- 0.15) microg/m(3). The significant difference between the two groups was observed (z = 8.045, P < 0.01). The levels of the lymphocyte subsets (CD3(+), CD3(+)CD4(+), CD3(+)CD8(+) and CD4(+)/CD8(+)) in exposed group were (30.08 +/- 17.75)%, (1.04 +/- 1.73)%, (11.94 +/- 9.78)%, 0.10 +/- 0.14. While, those of control group were (63.00 +/- 13.57)%, (30.51 +/- 5.16)%, (14.82 +/- 4.59)%, 2.17 +/- 0.53, higher than that of the exposed group (z values were 4.484, 5.227, 1.976, -5.218, respectively, P < 0.05).

CONCLUSIONOn the basis of individual air monitoring, the cellular immune function affected by soluble chromate is mainly based on T lymphocyte inhibition. The indicators CD3(+)CD4(+) mentioned above may be considered as efficient biomarkers in further research.

Objective: To investigate the associations between the numbers of healthy lifestyles and overweight/obesity and abdominal obesity in adult twins in Shanghai. Methods: Based on the Shanghai Twin Registry System Phase Ⅱ survey data in 2017-2018, a case-control study was conducted to analyze the association between healthy lifestyles and obesity and further adjusted for confounders by a co-twin control study. Results: A total of 7 864 adult twins (3 932 pairs) were included. In the co-twin case-control analysis for monozygotic twins, compared with participants with 0 to 2 healthy lifestyles, those with 3 and 4 to 5 healthy lifestyles had a 49% (OR=0.51, 95%CI: 0.28-0.93) and 70% (OR=0.30, 95%CI: 0.13-0.69) lower risk of overweight/obesity, respectively, and a 17% (OR=0.83, 95%CI: 0.44-1.57) and 66% (OR=0.34, 95%CI: 0.14-0.80) lower risk of abdominal obesity, respectively. For each additional healthy lifestyle, the risk of developing overweight/obesity was reduced by 41% (OR=0.59, 95%CI: 0.42-0.85), and the risk of developing abdominal obesity was reduced by 37% (OR=0.63, 95%CI: 0.44-0.90). Conclusion: An increasing number of healthy lifestyles was associated with a marked decreased risk for both overweight/obesity and abdominal obesity.
