Acute pancreatitis (AP) is a life-threatening gastrointestinal disorder for which no effective pharmacological treatments are currently available. One of the pharmacological targets that merits further research is the neurokinin 1 receptor (NK1R), which is found on pancreatic acinar cells and responds to the neuropeptide substance P (SP) that participates in AP. Although a few studies have stated the involvement of SP/NK1R in neurogenic inflammation in AP development, the regulatory mechanism remains unclear. In this study, we found that following activation of NK1R by SP, β-arrestin1, a scaffold protein of NK1R, down-regulated transcription of Adss, Adsl, and Ampd in the purine nucleotide cycle, thereby inhibiting mitochondrial function through fumarate depletion. Interestingly, we identified magnolol as a new and natural NK1R inhibitor with a non-nitrogenous biphenyl core structure. It exhibited a beneficial effect on AP by restoring purine nucleotide cycle metabolic enzymes and fumarate levels. Our study not only provides new therapeutic strategies, leading compounds, and drug translation possibilities for AP, but also provides important clues for the study of downstream mechanisms driven by SP in other diseases.

Objective:To analyze factors related to clinic attendance for contracted residents in a community health service center in Shanghai.Methods:It was a cross-sectional study. Through the 'Cloud Management of the Community' APP and the 'Service Fee of Contracted Residents' APP, the basic information, contracted time, hospital visits, number of visits, and medical insurance expenses of the contracted residents in Shanggang Community Health Service Center in 2021 were collected, the visiting rate to the contracted community health center and the contracted medical combination hospitals were analyzed.Results:In 2021, the contracting rate of all residents in the community was 49.96% (51 478/103 033). The contracting rate of the key population was 84.59% (43 545/51 478),among whom 66.28% (34 118/51 478) were over 60 years, 49.93% (25 702/51 478) had been contracted for more than 3 years, and 37.43% (19 270/51 478) had hypertension and/or diabetes. The number of contracted general practitioners was 4.89 times of contracted TCM doctors (1 345.17/274.81). Among all contracted residents 78.75% (40 540/51 478) had at least one visit annually, and 65.00% (33 463/51 478) had at least one visit to community health service center and the average number of visits was 17.63(5.00, 24.00)annually. The rate of visit to contracted the community health service center was (46.97±38.37) %, and 41.78% (16 937/40 540) had≥60% visit to contracted community center; the average visiting rate to the combination hospitals was (70.59±34.57) %, and 55.75% (22 602/40 540) had consultation rate≥80%. These residents were older in age, had longer contract time, higher proportion of hypertension and diabetes, and higher medical expenses, compared to those with less visits to contracted community health center and combination hospitals ( P<0.01). Meanwhile, 11 736 residents (35.07%) only visited to the contracted community health service center. Conclusion:The contracted residents are mainly the elderly and the sick ones in the community, but the use of contracted service is inadequate. Improving the visiting rate to community health center is a challenge for make a full use of the contracted health facilities.

Objective:To investigate the normal reference values of spinal bone mineral density measured by quantitative computed tomography (QCT) and the differences of bone mineral density (BMD) in different regions of in Chinese adult males.Methods:Men who underwent low-dose CT lung scan for cancer screening in regions of Northeast, North, East, South, Central and Southwest of China from January 2018 to December 2019 were selected. And the lumbar vertebrae BMD values in the male subjects were measured by the QCT system (Mindways Software, Inc.). The mean BMD values and their decline rates were calculated at an age interval of 10 years, and the prevalence of osteoporosis was calculated according to the American College of Radiology spine QCT osteoporosis diagnostic criteria.Results:A total of 50 682 males with a mean age of (50.22±12.79) years (ranged 20 to 98 years) were included in this study. The peak BMD of (173.11±28.56) mg/cm 3 in the healthy Chinese adult male population appeared in the age group of 20 to 29 years and then declined with age. Before the age of 70 years, the BMD was relatively higher in males in South China, and it was lower in Central China and Southwest China, and it was intermediate in Northeast, North and East of China, with statistically significant differences. There was no significant differences in BMD in the males in the two age groups of 70 to 79 years and 80 and older among the regions in China. The overall decline rate of spinal BMD in Chinese males under QCT was about 46.92% over the lifetime, and it declined obviouslyin the 40-49 age group. The overall prevalence of osteoporosis in Chinese male population aged 50 years and above was approximately 11.42%, with the highest prevalence in Southwest China and Central China (14.72% and 13.87%, respectively) and the lowest in North China and South China (8.53% and 7.71%, respectively). Conclusions:A reference of lumbar spine BMD values for healthy males in China based on QCT is established. BMD values were highest in South China and Lowest in Central China.
