Objective To investigate current status of obesity and its relationship with hypertension in the elderly over 65 in Fujian. Methods From February 2018 to March 2020, cluster sampling method was used to select 11 203 elderly people over 65 years old from residential areas and villages with concentrated population, representative medical and economic development level in Fujian, such as Fuzhou, Xiamen, Zhangzhou, Quanzhou, Sanming, Putian, Nanping, Longyan and Ningde. All the selected individuals completed the questionnaires, and the basic data including height, weight, waist circumference, hip circumference and blood pressure were measured. Results Among the 11 203 elderly people over the age of 65 in 9 city, there were 5 224 males, 5 979 females, 4 545 patients aged 65-70 years, 3 239 patients aged 70-75 years, 2 200 patients aged 75-80 years, and 1219 patients aged > 80 years. There were 309 cases of low weight (2.76%), 4 971 cases of normal weight (44.37%), 4 362 cases of overweight (38.94%) and 1561 cases of obesity (13.93%). The obesity rate of females was significantly higher than that of males, and the height and overweight rates of males were significantly higher than that of females (P<0.05). The overweight and obesity rates had significant difference among different age groups (P<0.05), which were the highest in 65-70 age group, being 31.41% and 45.17% respectively. SBP, DBP, normal blood pressure, stage I hypertension and hypertension in obesity group were significantly higher than those in other BMI groups (P<0.05). Among all age groups, the normal blood pressure and prehypertension of >80 age group were lower than those of other age groups, and the detection rate of hypertension was significantly higher than that of other age groups (P<0.05). Conclusion Overweight is more common among the elderly over 65 in Fujian, and the prevalence of hypertension is relatively high among people with low BMI.

Objective To analyze the incidence and death of stroke and its influencing factors, to explore the relationship between a stroke and its influencing factors, and to provide a scientific basis for the formulation and evaluation of health policies for the prevention and treatment of stroke. Methods Using a multi-stage stratified random cluster sampling method, a cross-sectional survey was conducted among 18 942 permanent residents over 40 years old . A unified questionnaire was used to analyze and understand the demographic characteristics of the research subjects. The statistical analysis was performed to compare the prevalence of stroke by gender, age, urban and rural areas, education, marital status and occupation. According to the results of single factor analysis, the Logistic model and artificial neural network model of influencing factors of stroke in the city were established. Results There were 522 stroke cases with a prevalence rate of 2.76%. There were 7 cases of death, accounting for 1.34%. The prevalence of stroke increased with the increase of age, and the trend test showed a statistical significance (P<0.01). The prevalence of stroke in primary school was higher than that in junior high school and above (P<0.01). The prevalence in rural areas was higher than that in urban areas (P<0.01). The prevalence in smokers and drinkers was higher than that in non-smokers and non-drinkers (P<0.01). Physical examination and laboratory examination showed that the waist circumference, BM, SBP, DBP, FPG, TC, TG and HDL of stroke patients were higher than those of non-stroke patients (P<0.01). The ankle brachial index and LDL value were significantly lower than those of non-stroke patients (P<0.01). Multivariate analysis showed that after adjusting gender, age, and urban and rural areas, smoking, drinking, waist length, high blood pressure measurement and high-density lipoprotein abnormality were positively correlated to stroke. Conclusion Smoking, drinking, waist length, high blood pressure and HDL were positive influencing factors of stroke. It is suggested that the intervention measures should be formulated according to the characteristics of different populations to effectively prevent and control strokes.

Objective To analyse the clinical effects on colon cancer with acute intestinal obstruction.Methods 56 patients with acute intestinal obstruction caused by colon cancer were studied retrospectively.The experience of diagnosis was summarized.Results 47 patients with acute intestinal obstruction caused by colon cancer received Stage Ⅰ tumor resection and the other 9 patients received different stages.54 patients healed (96.4％) and 1perioperative deaths (1.8 ％).Postoperative complications occurred in 18 cases (32.1％) including incision infection,intraperitoneal infection and intestinal fistula.Conclusion Stage Ⅰ tumor resection is feasible and safe surgical procedures for acute intestinal obstruction caused by colon cancer.

Lactic acid has a wide range of uses in the chemical, pharmaceutical and food industry. With rapid development of poly (lactic acid) industry, the demand for polymer-grade L-lactic acid is continuously increasing. Developing low-cost, non-food-biomass-lactic-acid fermentation process and the fermentation-separation coupled technology are trends to reduce polymer-grade L-lactic acid production cost. This review summarized the most recent advances in low-cost L-lactic acid fermentation based on the use of non-food biomass, followed by addressing the key issue that might be strategically important for future development of polymer-grade L-lactic acid production in industry.
