Objective:To analyze the etiological characteristics, serotype distribution, drug resistance and molecular typing characteristics based on data collected by active surveillance of foodborne diseases in Shanxi Province from 2021 to 2022.Methods:Fecal and anal swabs for foodborne disease tests were collected from 17 sentinel hospitals in Shanxi Province from 2021 to 2022. The pathogens included Shigella, Salmonella, Vibrio parahaemolyticus and 5 types of diarrheagenic Escherichia coli ( E. coli). The positive strains were identified by mass spectrometry or systematic biochemistry. Salmonella and Shigella were serotyped by slide agglutination, and diarrheagenic E. coli was typed by multiplex fluorescence PCR. Vibrio parahaemolyticus was tested for tlh/ tdh/ trh virulence genes by multiplex fluorescent PCR. All strains were also tested for drug resistance by the microbroth dilution method. Molecular typing was performed by pulsed-field gel electrophoresis (PFGE). Results:A total of 4 481 samples were collected from patients with diarrhea, and 555 target strains were detected, with a detection rate of 12.39%(555/4 481). Among them, there were 365 strains of Salmonella, 175 strains of diarrheagenic E. coli, 15 strains of Vibrio parahaemolyticus, and no Shigella. There were 32 serotypes of Salmonella, and the dominant serotypes were 158 strains of Salmonella senteritidis and 124 strains of Salmonella typhimurium. diarrheagenic E. coli classification: 79 strains of enteroaggregative E. coli, 72 strains of enteropathogenic E. coli, 23 strains of enterotoxic E. coli, 1 strain of enterohemorrhagic E. coli, and none of enteroinvasive E. coli. For Vibrio parahaemolyticus virulence gene carriage, all strains carried tlh; 11 strains (73.33%, 11/15) carried tdh only; 2 strains (13.33%, 2/15) carried trh; 1 strain (6.67%, 1/15) carried both tdh and trh genes; 1 strain (6.67%, 1/15) did not carry these two virulence genes. Antimicrobial resistance tests presented that Salmonella had the highest resistance rate to ampicillin (85.21%, 311/365), followed by naphridic acid (66.58%, 243/365), and multi-drug resistance (78.63%, 287/365), resulting in 135 drug resistance spectrums. The resistance rate of diarrheagenic E. coli to ampicillin was the highest (81.71%, 143/175), followed by tetracycline (67.43%, 118/175), and multi-drug resistance (72.57%, 127/175), resulting in 81 drug resistance spectrums. Vibrio parahaemolyticus had the highest resistance rate to cefazolin (93.33%, 14/15), followed by tetracycline (26.67%, 4/15) and multi-drug resistance (20.00%, 3/15), resulting in 3 drug resistance spectrums. A total of 158 strains of Salmonella enteritidi, 124 strains of Salmonella typhimurium, 13 strains of Salmonella london and 175 strains of DEC were typed by PFGE. Among 470 strains of PFGE typing, 6 strains of DEC were degraded by DNA, while the remaining strains obtained effective PFGE band. Salmonella enteritidi were divided into 64 PFGE band types, Salmonella typhimurium were divided into 115 PFGE band types, Salmonella london were divided into 13 PFGE band types and diarrheagenic E. coli were divided into 165 PFGE band types. Conclusions:Shigella is not detected in the active surveillance, and Salmonella is detected most frequently. Salmonella and diarrheagenic E. coli have the highest resistance rates to ampicillin, and Vibrio parahaemolyticus has the highest resistance rates to cefazolin. The PFGE classification is polymorphic, and the dominant band type is not obvious. The evidence of multi-drug resistance suggests further strengthening monitoring and management of drug resistance.

This article introduces the experience of Academician SHI Xuemin in treatment of stroke combined with obstructive sleep apnea hypopnea syndrome. It is believed that this disease is the syndrome of "stroke of lung qi exhaustion". It is rooted at the deficiency of primary qi, and lung qi declining; and characterized by phlegm stagnation, qi reversion and mind blockage. This disease is manifested as somnolence-like symptoms, snoring-like breathing and sawing-like expectorating. The therapeutic regimen focuses on "governing qihai (sea of qi ), regulating the spirit and adjusting the orifice closure". The main acupoints include Neiguan (PC6), Shuigou (GV26) and Sanyinjiao (SP6) to regain the consciousness and open the orifices. Besides, Renying (ST9) is added to regulate the respiration, Baihui (GV20) and Sishencong (EX-HN1) to harmonize the spirit, and Fengchi (GB20), Wangu (GB12) and Yifeng (TE17) to open the orifice for the treatment of symptoms. It provides a new idea for the clinical diagnosis and treatment of stroke with accompanying symptoms.

Based on the theory of the liver's"using bitter herbs to nourish or purge"from Huangdi Neijing,this paper systematically elucidates the theoretical foundation for treating functional constipation from liver.Focusing on the physiological characteristic of"liver desires to disperse"and the pathological manifestation of"liver bitterness and urgency,"combined with the"liver communicates with the large intestine"theory,this paper establishes a diagnostic and therapeutic framework for managing functional constipation by regulating liver function.The pathological evolution of functional constipation manifests in three distinct stages:in the early stage,liver qi stagnation leads to large intestine qi obstruction,where damaged by an excess of seven emotions resulting in symptoms such as difficult defecation,abdominal bloating,and hypochondriac pain;in the middle stage,liver depression transforms into fire,scorching bodily fluids to generate dryness,thereby creating a pathological interplay of stagnation,fire,and dryness,which is marked by anal heat,dry mouth,and yellow urine;in the late stage,yin deficiency in liver and kidney causes large intestine malnutrition,resulting in a complex pathological state where yin deficiency,collateral blockage,dryness accumulation,and blood stasis intertwine,clinically manifesting as pellet-like stools(resembling sheep feces)and soreness and weakness of the waist and knees.In treatment,the formula design follows the principle of"sweetness to relieve,acridity to tonify,and sourness to purge,"with treatment principles varying across stages.In the early stage,the focus is on dispersing liver and regulating qi,and unblocking the zang-fu viscera;in the middle stage,the priority shifts to clearing heat-fire,nourishing large intestine,and promoting fluid production;whereas,in the late stage,the emphasis lies on nourishing yin,unblocking collaterals,and promoting blood circulation.This staged treatment of functional constipation overcomes the limitations of solely focusing on nourishing large intestine and facilitating feces excretion,thereby advancing the treatment of different stages based on syndrome differentiation and personalized treatment.It provides theoretical support for improving patients' intestinal function and enhancing overall health outcomes.

Ulcerative colitis （UC） is a commonly seen digestive system disease with unclear pathogenesis. The condition is complex and variable， often chronic， and has a long treatment period with no specific cure. Currently， the treatment of UC often involves the use of corticosteroids， aminosalicylates， and biologics in western medicine， which provide fast-acting and definite efficacy in the short term. However， with prolonged medication， some patients may develop drug resistance and worsening of the disease， leading to the occurrence of colon cancer. Research has found that oxidative stress is one of the important pathogenic factors in UC and influences its onset and development. Oxidative stress is a state of imbalance between oxidative products and the antioxidant system in the body， characterized by overexpression of oxidative products such as malondialdehyde （MDA）， reactive oxygen species （ROS）， nitric oxide （NO）， or deficiency of antioxidant enzymes such as superoxide dismutase （SOD）， catalase （CAT）， and glutathione （GSH）. It is worth noting that traditional Chinese medicine （TCM）， as a unique characteristic medicine of China， has achieved significant efficacy in the treatment of UC. Studies have shown that TCM effectively inhibits the occurrence of UC by suppressing the accumulation of metabolites and antagonizes the development of UC by enhancing the antioxidant system. Therefore， using TCM to regulate the oxidative balance as a diagnostic and therapeutic approach may be a new method and direction for the treatment of UC in the future. Based on the above research， this article summarized the mechanisms of key pathogenic proteins in oxidative stress and the occurrence and development of UC， and compiled the effective ingredients of Chinese medicine， single drugs， prescriptions， and acupuncture and moxibustion in regulating upstream and downstream target proteins of oxidative stress. These interventions can reduce pathological damage to the intestinal mucosa， lower the colon injury index， enrich the intestinal microbiota， increase colon length， and improve clinical symptoms of UC. The article is expected to expand the application of TCM in the treatment of UC and provide a reliable scientific theoretical basis.

Objective: ICMM occupational health risk assessment model was be used to evaluate the risk of a lead-acid battery enterprise. Methods: In November 2016, a lead-acid battery company in Jiangsu Province was selected as the research object. Based on the occupational health survey data and occupational hazard assessment reports, the ICMM risk assessment model was used to conduct occupational health risks in eight key positions of a lead-acid battery enterprise. The risk assessment results was verified by actual test results. Results: In the quantitative assessment model, the occupational health risk assessment results for the castings and welding positions exposed to lead smoke, and the occupational health risk assessment results for the grinding and dividing positions exposed to lead dust existed unacceptable risks. The occupational health risk assessment results for the ball-milled and plated positions exposed to lead dust existed tolerable risks. The occupational health risk assessment results for the lead-plated and soldered positions exposed to sulphuric acid pastes and acids existed potential risks. In qualitative evaluation matrix method, the occupational health risk assessment results for the castings and welding positions exposed to lead smoke, and the occupational health risk assessment results for the grinding and dividing positions exposed to lead dust existed high risks, the occupational health risk assessment results for other four key positions were considered to be with low risks. Conclusion The key control points for lead smoke in this enterprise were castings and welding positions; The key control points for lead dust were the grinding and separating brush positions. The quantitative assessment model and the qualitative assessment matrix method in the ICMM model were consistent with the actual test results in the eight health risk assessments of occupational hazards in key positions. Therefore, the method could be applied to the assessment of occupational health risks of the lead-acid battery enterprise. According to the results of the assessment, improvements could be made to high-risk positions and the concentration of occupational hazards in high-risk posts could be reduced to better protect the health of workers.

Objective: To investigate the antimicrobial resistance status and pulsed field gel electrophoresis (PFGE) patterns of Salmonella enteritidis (S.enteritidis) in Shanxi Province in order to provide references for the treatment of Salmonella infection and for tracing the source of outbreaks of foodborne diseases. Methods: Sixty-four S. enteritidis strains were collected by monitoring sites for foodborne diseases from April 2015 to March 2018. Biochemical identification system and serotyping analysis were used for bacterial identification. Drug susceptibility patterns were analyzed with micro-broth dilution method. PFGE was used for molecular typing. Results: The antimicrobial resistance rate of 64 S. enteritidis strains to nalidixic acid (95.31%) was the highest, followed by that to ampicillin (90.63%) and to ampicillin/sulbactam (81.25%). They had lower resistance rates to cefazolin, cefotaxime, tetracycline, ceftazidime, trimethoprim/sulfamethoxzole and ciprofloxacin (3.13%-23.44%) and were all sensitive to chloramphenicol, cefotaxime, azithromycin, imipenem and gentamicin. No statistically significant difference in drug resistance rates was found between the sporadic strains and the outbreak strains (P>0.05). All 64 S. enteritidis strains digested with XbaⅠwere divided into 33 molecular patterns by PFGE. The numbers of bacteria contained in each pattern ranged from 1 to 10 strains. The similarity among patterns was between 54.6% and 100%. Conclusion More attention should be paid to the drug resistance status of S. enteritidis in Shanxi Province. It is necessary to strengthen the standardized administration of antibiotics. The PFGE patterns of S. enteritidis reveal the presence of significant genetic polymorphism. PFGE is of great significance in analyzing the genetic relationship among S. enteritidis strains and in identifying and tracing the source of outbreaks of foodborne diseases.

Objective To explore the mechanism of cell apoptosis of immortalized human keratinocytes (HaCaT cells) and protein expression related to this process after long term exposure to sodium arsenite (NaAsO2,1.0 μmol/L).Methods Malignant transformation model was set up through long-term exposure of HaCaT cells to 1.0 μmol/L NaAsO2.Cell passage for 0,1,7,14,21,28 and 35 generations in the process of malignant transformation were collected for measurement of cell apoptosis rate by flow cytometry,and apoptosis related proteins by Western blotting,including activation of cysteine protease 3,8 (cleaved-caspase-3,8),C/EBP homologous protein (CHOP),B-cell leukemia/lymphoma 2 (Bcl-2),and Bcl-2 associated X protein (Bax).Results Along with the arsenite treatment,the apoptosis levels were significantly decreased (F =26.770,all P ＜ 0.05),the apoptosis levels (0.307 ± 0.049,0.213 ± 0.055,0.163 ± 0.057,0.147 ± 0.035,0.053 ± 0.012) of the 7th,14th,21st,28th and 35thgenerations of cells after arsenite treatment were lower than that of control group of the 0th generation (0.393 ±0.021,all P ＜ 0.05).Compared between generations,there were statistical differences of the protein expression levels of cleaved-caspase-3,Chop,Bax and Bcl-2 in arsenite group (cleaved-caspase-3:1.000 ± 0.000,1.030 ± 0.027,1.104 ± 0.069,1.016 ± 0.087,0.838 ± 0.075,0.753 ± 0.082,0.677 ± 0.073;Chop:1.000 ± 0.000,1.059 ± 0.018,0.934 ± 0.095,0.976 ± 0.216,0.793 ± 0.136,0.651 ± 0.042,0.564 ± 0.056;Bax:1.000 ± 0.000,1.069 ± 0.037,1.028 ± 0.042,0.954 ± 0.118,0.641 ± 0.135,0.531 ± 0.132,0.429 ± 0.085;Bcl-2:1.000 ± 0.000,1.072 ± 0.023,1.249 ± 0.134,1.334 ± 0.143,1.633 ± 0.221,1.507 ± 0.152,1.461 ± 0.145,F =7.730,7.355,27.802,12.438,all P ＜ 0.05),compared with control group of the 0th generation (1.000 ± 0.000) and the same generation control group (1.000 ± 0.000),after the 21st generation,the differences were statistically significant (all P ＜ 0.05),while there was no difference of the protein expression levels of cleaved-caspase-8 (F =0.832,P ＞ 0.05).Conclusion In the process of malignant transformation,the apoptosis levels of HaCaT cells are inhibited after long term sodium arsenite exposure through mitochondria and endoplasmic reticulum (ER) stress signaling pathways.
