This study compares and analyzes the similarities and differences between National Health Strategy in America and Healthy China 2030 from three aspects, namely the strategic goals, the main contents, and the leading health indicators.Considering China's social and economic environment, this paper proposes the following suggestions: 1) to emphasize the relevance, dynamics and continuity of health strategy;2) to focus on key population on the basis of full coverage;3) to identify the focus of each phase of implementation;and 4) to highly think of the establishment of systems, including information system, operational supervision system and evaluation index system, etc.These suggestions are meant to provide inspiration to the introduction and further development of the China's national health strategy.

Objective To evaluate the role of 3.0 Tesla magnetic resonance hysterosalpingography (MR?HSG) work?up in the diagnosis of female infertility. Methods Between July 2015 and December 2018, a total of 1 052 infertile women aged from 20 to 40 years in the Affiliated Hospital of Nanjing University of Chinese Medicine were prospectively enrolled in the study. All the patients underwent pelvic plain scanning and X?ray hysterosalpingography (HSG) followed by MR?HSG examination, and the patency of the fallopian tubes as well as the abnormalities of the uterus and ovaries were evaluated. Among which 33 cases were randomly selected. The chi?square test and Kappa test were used to compare the difference and the consistency of the two methods in the evaluation of fallopian tubes. Results MR?HSG and HSG had good consistency in evaluating tubal patency (Kappa=0.88, P<0.01), and there was no statistically significant difference between the two groups (P=0.65). The examination of MR?HSG was successfully completed in 97.1%(1 021/1 052) cases. There were 81.7% (834/1 021) cases had at least one abnormality. Bilateral tubal, uterine and ovarian abnormalitiesoccurred in 42.6% (435/1 021), 34.2% (349/1 021)and 46.8% (478/1 021) cases, respectively. In which tubal abnormalities display the results as follows: bilateral obstructed 4.7% (48/1 021), bilateral poor pass 8.5% (87/1 021), one smooth one obstructed11.7% (119/1 021), one smooth one poor pass 12.6% (129/1 021), and one poor pass one obstructed 5.1% (52/1 021). Conclusion 3.0 T MR?HSG is expected to be a routineexam for evaluating female infertility, which allows a comprehensive assessment of tubal patency and other pelvic abnormalities of infertile women.

Objective: To analyze the burden of disease attributable to low fruit intake among Chinese population aged ≥15 years old between 1990 and 2013. Methods: We used data from the 2013 Global Burden of Disease Burden of Disease Study to study the situation in China. The population attributable fraction was calculated to estimate and compare the death and disability-adjusted life years (DALY) attributed to low fruit intake between 1990 and 2013 in China (excluded Taiwan, China). An average world population age structure of the period 2000-2025 was adopted to calculate age-standardized rates. Results: Deaths attributable to low fruit intake accounted for 11.02% of all death in 2013, which were higher than it in 1990 (10.38%). In 2013, the number of deaths attributed to low fruit intake in China increased to 1 046 500 from 793 800 in 1990. From 1990-2013, the age-standardized death rate attributable to low fruit intake decreased from 113.04/100 000 to 79.80/100 000. DALYs caused by low fruit intake increased from 18.346 5 million in 1990 to 21.296 7 million in 2013. Compared with 1990, the age-standardized DALY rate attributed to low fruit intake decreased by 34.67%. In 2013, the top three provinces with the highest burden of disease attributed to low fruits intake were Tibet, Guizhou and Xinjiang provinces, with standardized DALY rate at 2 612.53/100 000, 2 281.85/100 000 and 2 198.22/100 000, respectively. Compared with the results in 1990, the standardized DALY attributed to low fruits intake decreased, especially in Tianjin, where decreased by 63.61%; followed by Aomen, Zhejiang, Shanghai and Beijing, where decreased by 59.74%, 59.53%, 56.64% and 53.88%, respectively. Conclusion Compared with the situation in 1990, the burden of disease attributable to low fruit intake decreased in 2013, but the situation is still serious, especially in Tibet, Guizhou and Xinjiang provinces, where the burden decreased comparatively slowly.

Nonalcoholic fatty liver disease （NAFLD） has gradually become the main reason affecting human liver health， and many factors are involved in the development and progression of NAFLD. Mitochondria， as the “energy factory” of cells， plays an important role in maintaining normal physiological functions. Studies have shown that hepatic mitochondrial dysfunction promotes the development and progression of NAFLD. This article briefly introduces the latest research advances in the basic characteristics and physiological function of liver mitochondria and reviews new research findings in the association of mitochondrial dysfunction with obesity， simple fatty liver disease， and nonalcoholic steatohepatitis， in order to provide new ideas for the research on targeted mitochondrial therapy for NAFLD.

As a novel mode of cell death, pyroptosis plays an important role in nonalcoholic fatty liver disease (NAFLD), and the research on pyroptosis may help to explore new therapeutic targets for NAFLD. This article reviews the advances in pyroptosis from the research background and mechanism of pyroptosis and the role of pyroptosis in NAFLD and elaborates on the pyroptosis execution molecules such as GSDME and caspase-11 and the function of inflammasomes including AIM2.

Hepatic cholesterol accumulation is an important contributor to hypercholesterolemia, which results in atherosclerosis and cardiovascular disease (CVD). ATP-citrate lyase (ACLY) is a key lipogenic enzyme that converts cytosolic citrate derived from tricarboxylic acid cycle (TCA cycle) to acetyl-CoA in the cytoplasm. Therefore, ACLY represents a link between mitochondria oxidative phosphorylation and cytosolic de novo lipogenesis. In this study, we developed the small molecule 326E with an enedioic acid structural moiety as a novel ACLY inhibitor, and its CoA-conjugated form 326E-CoA inhibited ACLY activity with an IC₅₀ = 5.31 ± 1.2 μmol/L in vitro. 326E treatment reduced de novo lipogenesis, and increased cholesterol efflux in vitro and in vivo. 326E was rapidly absorbed after oral administration, exhibited a higher blood exposure than that of the approved ACLY inhibitor bempedoic acid (BA) used for hypercholesterolemia. Chronic 326E treatment in hamsters and rhesus monkeys resulted in remarkable improvement of hyperlipidemia. Once daily oral administration of 326E for 24 weeks prevented the occurrence of atherosclerosis in ApoE^-/- mice to a greater extent than that of BA treatment. Taken together, our data suggest that inhibition of ACLY by 326E represents a promising strategy for the treatment of hypercholesterolemia.
