ABSTRACT

@#Abstract: Objective To analyze the industry characteristics of new occupational pneumoconiosis in Foshan from 2007 to Methods 2021. The data of new cases of occupational pneumoconiosis in Foshan City from 2007 to 2021 were obtained from “ ” , “ the China Disease Prevention and Control Information System subsystem the Occupational Disease and Health Hazardous ”, Results Factors Monitoring Information System and the industry characteristics of the cases were analyzed. From 2007 to , , ( ) 2021 there were 886 new cases of occupational pneumoconiosis in Foshan mainly include silicosis 68.3% in males ( ), ( ) 94.2% and stage Ⅰ pneumoconiosis cases 75.9% . The median age of cases at the time of diagnosed disease was 47 years , old and the median working age of dust exposure was 11.2 years. The enterprises where all cases are located involve eight top , ; , - industry categories of which manufacturing industry accounted for 97.6% and 30 major industry categories of which non ( ) , metallic mineral products industry was the highest 60.5% . There were 554 sporadic cases and 332 cluster cases and the , , Conclusion industries were mainly non-metallic mineral products accounting for 55.0% and 69.6% respectively. , - Occupational pneumoconiosis in Foshan is dominated by silicosis and the key industries are non metallic mineral products.

ABSTRACT

Objective:To explore the biological basis underlying the different syndromes of nontraumatic osteonecrosis of the femoral head (NONFH) according to the molecular interaction network associated with syndromes and the corresponding prescriptions. Method:A total of 30 NONFH patients and 10 healthy controls were enrolled in the present study. The gene expression profiles associated with different syndromes of NONFH were detected by microarray analysis. Then, the molecular interaction networks of the differentially expressed genes of different syndromes were constructed to identify the crucial syndrome-related genes. After collecting the phenotype-related genes and the candidate targets of the corresponding prescriptions of different syndromes from Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0 (http://www.tcmip.cn/), the molecular interaction network associated with syndromes and the corresponding prescriptions were constructed and the biological basis of each syndrome was analyzed by functional enrichment analysis. Result:The crucial genes associated with the phlegm-stasis blocking collateral syndrome were mainly involved into the bone and lipid metabolism, and the regulation of immune-inflammation balance and circulation. Consistently, the candidate targets of the corresponding prescription-Jianpi Huogu prescription might play roles in the metabolism of osteogenesis, dissipating phlegm, activating circulation to remove blood stasis, relieving pain and inflammatory response. In addition, our data revealed that the stagnation of meridians syndrome-related genes could be mainly involved into the regulation of circulation and inflammatory response, as well as the metabolism of lipid and bone. Accordingly, the corresponding prescription of this syndrome-Huoxue Tongbi Formula could exert the regulatory effects on osteogenesis and inflammatory response, as well as the activation of the circulation and qi-invigorating. Moreover, the crucial genes associated with the liver and kidney deficiency syndrome played roles in various pathological processes during NONFH, such as the abnormal bone and lipid metabolisms, the immune-inflammation imbalance, and the blocked blood circulation, which were in line with our findings on the pharmacological mechanisms of the corresponding prescription of this syndrome-Bushen Zhuanggu formula. Conclusion:The current study indicated that the phlegm-stasis blocking collateral syndrome may be mainly associated with the abnormal bone and lipid metabolisms. The molecular mechanisms underlying the stagnation of meridians syndrome may be the imbalance of "immune-inflammation" and the blocking circulation. Furthermore, the liver and kidney deficiency syndrome may be not only associated with the abnormal bone and lipid metabolisms, but also implicated into various biological pathways-related to inflammation and circulation. Interestingly, the pharmacological mechanisms of the corresponding prescriptions may be in accord to the biological basis of each syndrome.
