Osteoporosis (OP) is a systemic skeletal disease that primarily affects the elderly population, which greatly increases the risk of fractures. Here we report that Kindlin-2 expression in adipose tissue increases during aging and high-fat diet fed and is accompanied by decreased bone mass. Kindlin-2 specific deletion (K2KO) controlled by Adipoq-Cre mice or adipose tissue-targeting AAV (AAV-Rec2-CasRx-sgK2) significantly increases bone mass. Mechanistically, Kindlin-2 promotes peroxisome proliferator-activated receptor gamma (PPARγ) activation and downstream fatty acid binding protein 4 (FABP4) expression through stabilizing fatty acid synthase (FAS), and increased FABP4 inhibits insulin expression and decreases bone mass. Kindlin-2 inhibition results in accelerated FAS degradation, decreased PPARγ activation and FABP4 expression, and therefore increased insulin expression and bone mass. Interestingly, we find that FABP4 is increased while insulin is decreased in serum of OP patients. Increased FABP4 expression through PPARγ activation by rosiglitazone reverses the high bone mass phenotype of K2KO mice. Inhibition of FAS by C75 phenocopies the high bone mass phenotype of K2KO mice. Collectively, our study establishes a novel Kindlin-2/FAS/PPARγ/FABP4/insulin axis in adipose tissue modulating bone mass and strongly indicates that FAS and Kindlin-2 are new potential targets and C75 or AAV-Rec2-CasRx-sgK2 treatment are potential strategies for OP treatment.

Objective: To understand the current status of follow up of people living with HIV/AIDS by health service at grass root in rural area of Jiangxi province and related factors, and provide references for the promotion of the follow up by grass root health service. Methods: People living HIV/AIDS aged ≥18 years and diagnosed before 31 December 2017 in 6 townships of Xinjian, Yushan counties and Guixi city were included in the study in Jiangxi province. They had been followed up for more than one time after the first epidemiologic survey. The information about their demographic characteristics and HIV infection status were collected by using self-designed questionnaire. Univariate and multivariate logistic regression analyses were conducted to identify the factors that influencing the acceptance of follow up by grass root health service. Results: Of the 373 surveyed HIV infected subjects aged (53.06±16.15) years, 261 were males (70.0%, 261/373). Among the surveyed subjects, the illiteracy and people who received only primary school education accounted for 54.7% (204/373). The rate of follow up of the HIV infected subjects by grass root health service was 55.8% (208/373), and those through heterosexual contact were 58.5% (190/325). The multivariate regression analysis showed that the acceptance of follow up by grass root health service was higher in those who were farmers (OR=7.36, 95%CI: 2.52-21.45), had family support (OR=16.01, 95%CI: 2.25-49.73), didn’t worry about discrimination (OR=12.97, 95%CI: 4.75-35.42), trusted health care provider (OR=5.07, 95%CI: 2.19-11.76) and showed AIDS symptoms (OR=10.58, 95%CI: 2.25- 49.73). Conclusions The performance of follow up of people living with HIV/AIDS by grass root health service was well, suggesting it is a feasible management model. Being famer or not, family member supporting or not, worry about discrimination or not, trusting health care provider or not and showing AIDS symptoms or not were the main factors influencing the acceptance of follow up by grass root health service.

The HIV-infected people were investigated for their satisfactory situation towards the follow-up management of primary medical and health care institutions in Xinjian County, Yushan County and Guixi City of Jiangxi Province from January to July 2018 and related factors were also analyzed. The total score of the Infected Patients′ Follow-up Management Satisfaction Scale higher than 59 was defined as the satisfactory. 75.68% of 259 infected patients were satisfied with the follow-up management. Compared to farmers and other follow-up modes, non-farmers (OR=10.72, 95%CI: 2.07-55.63), and patients receiving follow-up service in responsible institutions (OR=6.44, 95%CI: 3.12-13.30) were more satisfied with follow-up management.
