ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis （IPF）. MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation （30 patients） and control groups （30 patients）. All patients underwent standard Western medical therapy. Additionally，the observation group received Shenlong decoction granules，while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each，taken twice daily for three months. The indexes of the patients during the treatment cycle were observed，and the main indexes include traditional Chinese medicine （TCM） syndrome scores and 6 min walk test （6MWT）. The secondary indexes include pulmonary function test ［actual value/expected value of total lung volume （TLC%），actual value/expected value of vital capacity（FVC%），actual/predicted diffusing capacity of the lung for carbon monoxide（DLCO%），actual/predicted forced expiratory volume in one second （FEV₁%），and FEV₁/ forced vital capacity （FVC）］，blood gas analysis ［arterial blood diathesis partial pressure of oxygen （PaO₂），partial pressure of carbon dioxide （PaCO₂），and arterial oxygen saturation （SaO₂）］，serum inflammatory factors ［transforming growth factor-β₁ （TGF-β₁），interleukin-4 （IL-4），interleukin-13 （IL-13），interleukin-12 （IL-12），and gamma-interferon （IFN-γ）］，and quality of survival evaluation ［St George's Respiratory Questionnaire （SGRQ） score］. The patients' clinical manifestations were determined at the end of the treatment， and the occurrence of adverse events was recorded. ResultsA total of 53 patients completed the study，comprising 27 in the control group and 26 in the observation group. Upon completion of the treatment period，the control group achieved a total effective rate of 33.33% （9/27），whereas the observation group demonstrated a total effective rate of 53.85% （14/26），which was statistically superior to the control group （χ²=4.034，P<0.05）. After the treatment，the TCM syndrome scores，6MWT，DLCO%，FEV₁%，PaO₂，PaCO₂，TGF-β₁，IL-4，IL-13，IL-12，and IFN-γ in the two groups were all significantly improved （P<0.01）. Compared with those in the control group after treatment at the same period，the TCM syndrome scores，6MWT，PaO₂，and PaCO₂ were significantly improved in the observation group after 60 days and 90 days of medication （P<0.01）. Three months after the end of medication，the SGRQ score in the observation group showed significant improvement when compared to that in the control group （P<0.05），and no severe adverse events were reported during the follow-up period. ConclusionCompound Shenlong decoction can alleviate clinical symptoms such as shortness of breath and wheezing in patients with lung deficiency and collateral stasis syndrome of IPF，enhance exercise tolerance，improve the quality of life，and have certain potential advantages in improving pulmonary function.

Objective:To learn about the monitoring indicators and patient management in coal-burning-borne endemic arsenic poisoning areas in Shaanxi Province, and provide a basis for consolidating and improving the prevention and control achievements.Methods:From March to December 2023, in accordance with the requirements of the "Notice of the Office of Shaanxi Provincial Health Commission on Issuing of the Monitoring Plan for Key Endemic Diseases Such as Kashin-Beck Disease" and "The Monitoring Plan for Endemic Fluorosis and Arsenic Poisoning in Shaanxi Province", a basic situation investigation was conducted in the affected villages of all counties (districts) with coal-burning-borne endemic arsenic poisoning in Shaanxi Province, and on-site visits were conducted to check the management of high arsenic coal mines. Using the simple random sampling method, 30 families in each village were selected to investigate the use of stoves and the formation of health-related behaviors. A survey on arsenic poisoning was carried out among all populations in the affected villages. According to the requirements of the provincial monitoring program, 720 people were randomly selected from 12 affected villages in 3 monitoring counties to measure their urinary arsenic level. The determination was based on the "Guidelines for the Safety of Urinary Arsenic in Population" (WS/T 665-2019). The evaluation for elimination of disease areas was carried out in accordance with the "National Health Commission Issued the Evaluation Approach for Control and Elimination of Priority Endemic Diseases (2019 edition)".Results:A total of 2 cities, 8 counties (districts), 99 townships, and 1 414 affected villages were monitored. All 53 high arsenic coal mines had stopped mining. The rate of qualified improved stoves was 99.97%; the correct utilization rate of qualified improved stoves, and the correct drying rate of corn and chili peppers provided for human consumption in the affected villages were 100.00%. A total of 2 064 138 people were examined, and 2 682 cases of arsenic poisoning were detected, all of whom were historical patients. There were no new cases of arsenic poisoning or skin cancer. There were currently 2 682 arsenic poisoning patients who had received family doctor contract services and implemented follow-up management. The geometric mean of urinary arsenic was 0.016 7 mg/L, which was lower than the safety guideline value for human urinary arsenic (0.032 mg/L).Conclusions:The monitoring indicators in the coal-burning-borne endemic arsenic poisoning areas in Shaanxi Province have reached the elimination standards. In the future, we should continue to strengthen the management of high arsenic coal mines, implement comprehensive prevention and control measures mainly focused on furnace and stove renovation and health promotion, and do a good job in patient management to continuously consolidate and improve the prevention and control achievements.

Objective:To learn about the operation of fluoride reduction and water improvement projects, the current situation of water fluoride level and the changing trend of fluorosis in drinking water-borne endemic fluorosis areas in Shaanxi Province, and to evaluate the effect of prevention and control measures.Methods:From March 2014 to December 2021, 15 endemic villages in drinking water-borne endemic fluorosis areas of Dali, Dingbian, Jingbian, Jingyang and Liquan counties in Shaanxi Province were selected as monitoring villages to investigate the operation of water improvement projects. Water samples were collected, and the water fluoride level was detected according to the "Standard Examination Methods for Drinking Water - Nonmetal Parameters" (GB/T 5750.5-2006). "Diagnosis of Dental Fluorosis" (WS/T 208-2011) was done to detect dental fluorosis in all children aged 8 - 12 who were born and lived in the monitoring village. Using "Diagnostic Standard for Endemic Skeletal Fluorosis" (WS/T 192-2008) and "Determination of Fluoride in Urine - Ion Selective Electrode Method" (WS/T 89-2015), X-ray examination and urine fluoride level test were performed on adults over 25 years old who had lived in the monitoring village for more than 5 years, respectively.Results:From 2014 to 2021, a total of 122 water improvement projects were investigated, all of which were in normal operation. The qualified rate of water fluoride increased from 81.25% (13/16) in 2014 to 100.00% (11/11) in 2021. A total of 5 595 children aged 8 - 12 were examined, 1 790 children with dental fluorosis were detected, with a detection rate of 31.99%. The detection rate of dental fluorosis in children decreased from 52.05% (304/584) in 2014 to 9.68% (93/961) in 2021, showing an overall downward trend (χ 2trend = 533.76, P < 0.001). In 2014, 791 adults were examined, and 256 patients with skeletal fluorosis were detected, the detection rate was 32.36%. In 2019, 770 adults were examined, and 88 patients with skeletal fluorosis were detected, with a detection rate of 11.43%. The detection rate of skeletal fluorosis in adults in 2019 was lower than that in 2014, and the difference was statistically significant (χ 2 = 99.54, P < 0.001). In 2014, 754 adult urine samples were collected, and the geometric mean of urine fluoride was 2.571 mg/L. In 2019, 770 adult urine samples were collected, and the geometric mean of urine fluoride was 1.292 mg/L. The geometric mean of urine fluoride in adults in 2019 was lower than that in 2014, and the difference was statistically significant ( Z = - 12.74, P < 0.001). Conclusions:From 2014 to 2021, the water improvement projects in drinking water-borne endemic fluorosis areas in Shaanxi Province are running normally, and the qualified rate of water fluoride has increased. The incidence of dental fluorosis in children and skeletal fluorosis in adults has decreased. In the later stage, it is necessary to continuously strengthen the monitoring and management of water improvement projects to prevent the rebound of water fluoride from causing residents' illness.

Objective:To evaluate the prevention and control effect of coal-burning-borne endemic fluorosis in Ankang City of Shaanxi Province, so as to provide a scientific basis for formulating precise prevention and control strategies in the future.Methods:From 2019 to 2023, according to the requirements of the "Monitoring Program of Shaanxi Province for Coal-burning-borne Endemic Fluorosis (2019 Edition)", full coverage monitoring was carried out in all affected villages in seven affected counties under the jurisdiction of Ankang City. Using the simple random sampling method, 30 households in each affected village were selected to investigate the use of improved stoves and the formation of health-related behaviors. All children aged from 8 to 12 in the village were examined for the prevalence of dental fluorosis. At the same time, 6 monitoring villages were selected in 2019, and 8 monitoring villages were selected in 2023 to collect real-time urine samples from children aged 8 - 12 for determination of urinary fluoride level. The evaluation for control and elimination of disease areas was carried out in accordance with the "Evaluation Approach for Control and Elimination of Priority Endemic Diseases (2019 Edition)".Results:From 2019 to 2023, a total of 203 880 households were monitored, the rate of qualified improved stoves and the correct use rate of qualified improved stoves were more than 95.00%. The utilization rate of improved stoves decreased from 16.34% (6 584/40 290) in 2019 to 8.89% (3 706/41 700) in 2023, showing a decreasing trend year by year (χ 2trend = 3 400.37, P < 0.001). The utilization rate of clean energy increased from 82.52% (33 247/40 290) in 2019 to 94.36% (39 350/41 700) in 2023, showing an upward trend year by year (χ 2trend = 7 506.09, P < 0.001). The correct drying rate of corn and pepper for human consumption were 100.00%. A total of 455 327 children aged 8 - 12 were examined, and 2 301 cases of dental fluorosis were diagnosed, with a detection rate of 0.51%. Children with dental fluorosis were mainly extremely mild and mild, accounting for 94.87% (2 183/2 301). The dental fluorosis index was 0.012, indicating no trend of fluorosis prevalence. The detection rate of dental fluorosis in children decreased from 0.81% (765/94 537) in 2019 to 0.24% (204/86 066) in 2023, showing a declining trend year by year (χ 2trend = 375.45, P < 0.001). The geometric mean urinary fluoride levels of children aged 8 to 12 in 2019 and 2023 were 0.48 and 0.42 mg/L, respectively, with statistically significant differences between groups ( Z = - 3.05, P = 0.002). As of 2023, 1 390 affected villages had met the elimination criteria. Conclusions:The prevention and control of coal-burning-borne endemic fluorosis in Ankang City has achieved remarkable results, with all seven affected counties reaching the elimination standard. In the future, we should strengthen the management of high fluoride coal mines, continue to promote the use of clean energy, strengthen health promotion and disease monitoring, and continuously consolidate and improve the results of prevention and control.

Objective:To study the epidemiological characteristics of mortality and cause of death composition in patients with coal-burning-borne endemic arsenism in Ankang City, Shaanxi Province.Methods:Mortality data of patients with coal-burning-borne endemic arsenism in Ankang City from 2018 to 2023 were collected from the Shaanxi Provincial Endemic Disease Prevention and Control Information Management Platform and the National Death Cause Information Registration System. Crude and standardized mortality rates, years of life lost (YLL) due to premature death were calculated, and the population and regional distribution characteristics of death cases were analyzed. Causes of death were classified and analyzed according to the International Classification of Diseases (ICD-10) category codes.Results:From 2018 to 2023, a total of 610 patients with coal-burning-borne endemic arsenism died in Ankang City, Shaanxi Province. The average annual crude mortality rate was 5.20/100 000. The average age of death for patients was 77.78 years old, and the mortality rate showed an upward trend with age (χ 2tend = 1 163.82, P < 0.001), with a significant increase in patients over 60 years old. The male to female ratio was 3.18∶1.00 (464/146). Among the seven diseased districts and counties, Langao County had the highest mortality rate. The YLL was 6 241.68 person-years. The top four causes of death among these cases circulatory system diseases, respiratory system diseases, malignant tumors, and injuries differed from those of the entire population in Ankang City, with respiratory system diseases being more prominently ranked. Conclusions:The death cases of coal-burning-borne endemic arsenism in Ankang City are mainly elderly males, and are more common in Langao County. There are various causes of death, coexisting with circulatory system diseases, respiratory system diseases, malignant tumors, and injuries.

Objective:To explore the effect and possible mechanism of Zexie Tang(ZXT)regulate the balance of M1/M2 polarization in macrophage cells.Methods:Lipid metabolism disorder mouse model was induced by Western diet(WD)in vivo,RAW264.7 cell M1/M2 macrophage model was induced by LPS/IL-4 in vitro,set up blank group,model group and ZXT group.The flu-orescence intensity of M1 and M2 macrophage markers in adipose tissue and RAW264.7 cells was observed by immunofluorescence staining;protein levels of p-AKT,AKT and COX-2 were measured by Western blot;levels of macrophage marker gene mRNAs of M1 and M2 were analysed by qPCR;IL-1β and IL-10 were measured by ELISA;content of NO was detected by Griess;binding of active components of Alismatis Rhizoma and Atractylodes Macrocephala with PI3K protein was analyzed by Docking.Results:Compared with WD group,expression of CD11c was significantly decreased in ZXT group,while expression of CD206 was significantly up-regulated;ZXT reversed LPS-induced increased in CD80 expression,down-regulated mRNA levels of M1 macrophage marker gene iNOS,etc,decreased the expression of COX-2 protein,and inhibited the secretion of IL-1β(P<0.001);ZXT promoted IL-4-induced CD206 expression,up-regulation of M2 macrophage marker gene Arg-1 and other mRNAs levels and secretion of IL-10;ZXT reversed the LPS-induced increased in NO release;p-AKT/AKT protein level increased in vivo and in vitro after ZXT administration;Docking re-sults show that many active ingredients in Alismatis Rhizoma and Atractylodes Macrocephala could form hydrogen bonds stably with PI3K protein.Conclusion:ZXT regulates the M1/M2 polarization balance of macrophages,and its mechanism may be related to the regulation of PI3K/AKT pathway.

Objective To investigate the correlation between the prevalence of dental fluorosis in children and the intake of dietary nutrients. Methods A total of 81 children aged 8-12 (34 males and 47 females) with fluorosis were randomly selected in the districts of Daxu, Fuping, and Fuyang in Shaanxi Province where the drinking water had been changed for more than 5 years. The diagnosis of dental fluorosis was carried out using Dean's method. According to the 1:1 case-control study method, 81 children aged 8-12 (34 males and 47 females) without dental fluorosis were selected as a control group. A ^“double meal method^“ was employed for dietary investigation for 3 consecutive days. The differences in dietary nutrient intake between the two groups of children were analyzed and compared. Results There was no significant difference between the two groups (P>0.05). Compared with the control group, the difference in the dietary intake of vitamin C, vitamin E, calcium, magnesium, iron, zinc, copper, phosphorus, and selenium in the fluorosis group was not statistically significant (P>0.05). The logistic regression analysis of the prevalence of dental fluorosis in children showed that the dietary nutrient magnesium was associated with the onset of dental fluorosis. Conclusion Within a certain range, dietary magnesium is a protective factor for children with dental fluorosis. It is suggested that school-age children in areas with excessive water fluoride should be supplemented with sufficient magnesium in their diets.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has become a severe global burden in terms of both health and the economy. Few studies, however, have thoroughly assessed the influence of air pollution on COPD-related mortality among elderly people in developing areas in the hinterland of southwestern China. This study is the first to examine the association between short-term exposure to ambient airborne pollutants and COPD-related mortality among elderly people in the central Sichuan Basin of southwestern China. METHODS: Data on COPD-related mortality among elderly people aged 60 and older were obtained from the Population Death Information Registration and Management System (PDIRMS). Data on airborne pollutants comprised of particulate matter < 2.5 μm in aerodynamic diameter (PM RESULTS: A total of 61,058 COPD-related deaths of people aged 60 and older were obtained.
