Objective:To analyze the predictive value of serological measures within 24 hours of admission in acute pancreatitis patients against patients with severe acute pancreatitis(SAP), because the severity of acute pancreatitis was characterized by a timely assessment and prediction by emergency department physicians upon visit.Methods:A total of 119 acute pancreatitis patients admitted in Emergency Department in Beijing Jishuitan Hospital, Capital Medical University from January 2022 to December 2022 were retrospectively collected. According to the revised Atlanta classification, patients were characterized by mild acute pancreatitis group (77 cases), moderately severe acute pancreatitis group (27 cases), and SAP group (15 cases). Basic characteristics, early disease severity scores and early serological indexes of the three groups were compared, independent risk factors of serological indexes affecting the occurrence of SAP were analyzed, and receiver operator characteristic curve was drawn, evaluate the predictive value of related serological indexes for SAP.Results:There were no significant differences in the basic characteristics of the three groups including of gender, age, BMI, type of pancreatitis and complications ( P>0.05), but there were significant differences in early BISPA, Ranson, APACHEⅡ and Panc3 scores among the three groups ( P<0.05).Albumin-bilirubin score ( OR=3.653, 95% CI 1.665-8.012, P=0.001), blood urea nitrogen ( OR=1.117, 95% CI 1.039-1.202, P=0.003) were independent risk factors for SAP. The areas under ROC curve predicted by albumin-bilirubin score, blood urea nitrogen and albumin-bilirubin score combined with blood urea nitrogen were 0.762, 0.776 and 0.857, respectively, which showed no statistical difference compared with earlier Ranson, BISAP and APACHE Ⅱ scoring systems, respectively ( P>0.05). Conclusions:Early albumin-bilirubin score and blood urea nitrogen indexes of acute pancreatitis patients have good predictive value for SAP. Albumin-bilirubin score combined with blood urea nitrogen can improve the predictive value of SAP, and the predictive effect is as good as early Ranson, BISAP and APACHEⅡ scoring systems.

Hyperparathyroidism is a common endocrine disease that seriously affects human health, depending on its etiology, which can be divided into three types: primary, secondary and tertiary. In clinical practice, we found that some primary hyperparathyroidism may be secondary or tertiary hyperparathyroidism caused by insufficient calcium intake and/or vitamin D deficiency/insufficiency, and become a common type of hyperparathyroidism. The daily calcium intake of Chinese people is generally insufficient. Vitamin D can promote the absorption of calcium, but vitamin D deficiency/insufficiency is also a worldwide public health problem. Long-term hypocalcemia will stimulate parathyroid hyperplasia and secrete excessive parathyroid hormone, resulting in parathyroid hyperfunction (pre-hyperparathyroidism) and then secondary hyperparathyroidism, both of which may damage bone and release calcium into blood, leading to diseases of multiple organs and tissues. The detection of bone metabolism indexes such as calcium, magnesium, phosphorus, parathyroid hormone and vitamin D may be helpful for the early diagnosis of pre-hyperparathyroidism and hyperparathyroidism. Supplementation of calcium and vitamin D in early stage can control the development of the disease and change "unpreventable and uncontrollable" into "preventable and controllable" . The health screening of bone metabolism indexes and parathyroid ultrasonography should be advocated, and the prevention and treatment of calcium and/or vitamin D insufficiency associated parathyroid hyperfunction and hyperparathyroidism should be strengthened, so as to greatly improve the bone health, urinary calculus, metastatic vascular calcification and systemic abnormal calcium migration and precipitation in the population.

OBJECTIVEThe aim of this study was to investigate the impact of air pollution on the number of pediatric outpatient and emergency room visits in January 2013.
METHODSHealth-related data was from a major hospital in Haidian,Beijing while related data on air pollution was from the Chinese Research Academy of Environmental Sciences. Data on weather was from the China Weather Website. Number of hospital outpatient visits per day during the haze period was compared to those from the previous year to get the increase of percentage. Concentration-response functions were estimated using generalized additive modeling with natural log link function, while multiple structural change test was used to determine the changing point in CRFs. Constrained piecewise linear function was used to estimate the risks for different segments of CRFs.
RESULTSThe peak of NO(X), SO₂, PM(2.5) and PM(10) reached 672.63 µ g/m³, 146.20 µ g/m³, 312.19 µ g/m³ and 995.00 µ g/m³, around 28 December 2012 and 10 January 2013. The peaks of visits to the pediatric department were observed at the some days, showing 47.75% and 34.14% of increase in the visits to the pediatric department. In the low or intermediate ranges of concentration, all the four air pollutants were significantly associated with pediatric outpatient visits, in the form of C- and S- shape of concentration-response function. However, in the range of high concentration, only PM(10) and SO₂were significantly associated with the number of visits to the pediatric emergency room, appeared as the J-shape form. Discernable thresholds were found in S- and J- shapes which were located at 200 µg/m³, 20 µg/m³, 40 µg/m³ and 100 µ g/m³ for NO(X), SO₂, PM(2.5) and PM(10), respectively.
CONCLUSIONAir pollution during the haze period was associated with the increase of pediatric outpatient and emergency room visits. There were different sensitive groups within the pediatric cases. Their susceptibility showed a decreasing trend from C-, S-, to J- shape related group.
