[摘 要] 目的：探究聚丝蛋白（FLG）在黑色素瘤组织中的表达及其与患者临床病理特征、预后的关系。方法：选取2019年6月至2020年8月间山东第一医科大学附属人民医院收治的70例黑色素瘤患者为研究对象，取术中切除的瘤组织及瘤旁组织标本，用免疫组织化学法检测FLG蛋白表达，根据FLG的表达将患者分为阳性组和阴性组，比较瘤组织、瘤旁组织及不同病理特征下黑色素瘤组织中FLG的阳性表达率。随访患者3年，根据患者预后情况将患者分为生存组（n = 43）和死亡组（n = 27），比较两组患者的FLG阳性表达率，采用Kaplan-Meier法绘制生存曲线，比较两组患者生存时间。结果：黑色素瘤组织中FLG表达阳性率显著低于瘤旁组织（P < 0.05）；FLG阳性组肿瘤直径 > 1 cm、Breslow厚度 > 2 mm、局部溃疡、TNM分级Ⅲ～Ⅳ级、淋巴结转移、肿瘤侵袭占比显著低于阴性组（P < 0.05或P < 0.01）；70例患者中死亡27例，生存43例，生存率61.42%，死亡组患者FLG表达阳性率显著低于生存组（P < 0.05），FLG表达阳性患者生存时间显著长于阴性患者（P = 0.010）；多因素Cox回归分析显示，Breslow厚度 > 2 mm、TNM分级Ⅲ～Ⅳ级、淋巴结转移、肿瘤侵袭是影响黑色素瘤患者预后的危险因素（P < 0.01或P < 0.001），FLG表达阳性为保护因素（P < 0.01或P < 0.001）。结论：黑色素瘤组织中FLG显著降低，且与肿瘤Breslow厚度、分期侵袭和淋巴结转移等病理特征及预后有关。

ObjectiveThis paper aims to analyze the current status of outcome indicators in randomized controlled trials （RCT） of traditional Chinese medicine （TCM） for treating chronic atrophic gastritis （CAG）， so as to provide references for constructing the core outcome set （COS） of TCM in the treatment of CAG. MethodChina National Knowledge Infrastructure （CNKI）， Wanfang， VIP， SinoMed， PubMed， Embase， and Cochrane Library databases were searched for RCTs of TCM in the treatment of CAG in the last five years. The risk of bias of included studies was evaluated， and the selection status of outcome indicators was statistically analyzed. ResultA total of 150 RCTs were included， with a sample size of 44-398 cases. 164 outcome indicators were reported， with an application frequency of 1 229 times. The outcome indicators were classified into seven indicator domains according to functional attributes， followed by physical and chemical examination （69.41%）， TCM syndrome （12.69%）， symptoms and signs （11.15%）， safety indicators （5.37%）， quality of life （0.65%）， long-term prognosis （0.65%）， and economic evaluation （0.08%）. According to the statistical analysis， there were problems in the selection of outcome indicators in RCTs of TCM for treating CAG， including various indicators， non-standard name reports， unclear primary and secondary indicators， random combination of subjective and objective indicators， neglected patient report outcome indicators， missing long-term prognosis and economic indicators， insufficient reporting of safety indicators， and inconsistent measurement tools and measurement time points. ConclusionIn the past five years， there have been many problems in the selection of outcome indicators in RCTs of TCM for treating CAG. It is necessary to actively promote the construction of the COS of TCM in the treatment of CAG and promote the high-quality development of clinical research of TCM.

OBJECTIVE To investigate the impact of noise exposure in metallurgical manufacturing on hearing.METHODS 245 workers exposed to noise in an enterprise and 51 administrative staff were tested for air conduction hearing threshold of pure tones at 0.5-8 kHz in both ears,and the equivalent sound level of workplace noise was measured for 8 hours.The hearing threshold of workers in different jobs was statistically analyzed.RESULTS The hearing threshold of workers exposed to noise at 0.5-8 kHz was significantly higher than that of administrative staff;hearing loss mainly occurred at 4 kHz and 6 kHz;the hearing threshold was positively correlated with working age and age,and the hearing threshold of workers over 40 years old and with working age of more than 6 years were higher than 40 dB HL at both ears at 4 kHz and 6 kHz.CONCLUSION The hearing loss of 4 kHz and 6 kHz is most obvious in noise-exposed workers,and age,working age,and noise exposure intensity were risk factors for hearing loss.It is necessary to strengthen the control of noise sources,attach importance to protective measures such as earplugs,and reduce noise exposure time.

OBJECTIVE To explore the clinical practice differences based on GBZ 49-2007 and GBZ 49-2014 diagnostic criteria for occupational noise induced hearing loss.METHODS Two hundred and sixty-five noise workers who applied for occupational noise induced hearing loss diagnosis in Hangzhou Occupational Disease Prevention and Treatment Center from January 2016 to November 2023 were selected and diagnosed according to the diagnostic criteria of GBZ 49-2007 and GBZ 49-2014 for noise induced hearing loss.RESULTS The diagnostic rate of occupational noise induced hearing loss in GBZ 49-2014 standard was 53.58%,which was significantly higher than the 42.64%in GBZ 49-2007 standard(P<0.05).The κ value of the diagnostic consistency between the GBZ 49-2014 standard and the GBZ 49-2007 standard for occupational noise induced hearing loss was 0.761,P<0.05,indicating good diagnostic consistency with a diagnostic consistency rate was 86.04%.The diagnostic rate of occupational noise induced hearing loss(GBZ 49-2007)among workers with work experience≥10 years was 59.05%,which was higher than that of workers with work experience<10 years(P<0.05).The diagnostic rate of occupational noise induced deafness in workers with work experience≥10 years(GBZ 49-2014)was 72.38%,which is higher than that of workers with work experience<10 years(P<0.05).According to the diagnosis of occupational noise induced hearing loss in GBZ 49-2007 and GBZ 49-2014,patients with work experience≥10 years had a higher severity of occupational noise induced hearing loss than those with work experience<10 years(P<0.05).CONCLUSION Compared to the GBZ 49-2007 standard,the GBZ 49-2014 standard will increase the diagnostic cases of occupational noise induced hearing loss;Under the GBZ 49-2007 and GBZ 49-2014 standards,the diagnosis and severity of occupational noise induced hearing loss are related to length of service.

Objective:To re-evaluate the reliability of the conclusions of the systematic reviews (SR)/meta-analysis (MA) of Traditional Chinese Medicine (TCM) in the treatment of functional dyspepsia (FD).Methods:CNKI, CBM, WanFang Data, VIP, PubMed, Cochrane Library, and Embase were searched from the establishment of the database to March 30, 2022. Two researchers independently screened literature and extracted data, and included SRs/MAs in the treatment of FD with TCM. The AMSTAR 2 and GRADE tools were used to evaluate the included the study carried out methodological quality evaluation, outcome evidence quality grading, and descriptive analysis of the main outcome.Results:A total of 28 SRs/MAs were included, with 34 outcome indicators. According to the AMSTAR 2 evaluation results, 21 SRs/MAs were of medium quality, and 7 SRs/MAs were of low quality. The GRADE quality of evidence grading results showed that of the 100 evidence bodies, 13 were of high quality, 58 were of moderate quality, 24 were of low quality, and 5 were of very low quality.Conclusion:TCM in the treatment of FD can improve the clinical efficiency, improve the cure rate, reduce the recurrence rate, and improve the clinical symptoms, but the methodological quality and evidence quality of related SRs/MAs have certain defects, so this conclusion should be treated with caution.

BACKGROUND: Given the general unavailability, common adverse effects, and complicated administration of tetracycline, the clinical application of classic bismuth quadruple therapy (BQT) is greatly limited. Whether minocycline can replace tetracycline for Helicobacter pylori ( H . pylori ) eradication is unknown. We aimed to compare the eradication rate, safety, and compliance between minocycline- and tetracycline-containing BQT as first-line regimens. METHODS: This randomized controlled trial was conducted on 434 naïve patients with H . pylori infection. The participants were randomly assigned to 14-day minocycline-containing BQT group (bismuth potassium citrate 110 mg q.i.d., esomeprazole 20 mg b.i.d., metronidazole 400 mg q.i.d., and minocycline 100 mg b.i.d.) and tetracycline-containing BQT group (bismuth potassium citrate/esomeprazole/metronidazole with doses same as above and tetracycline 500 mg q.i.d.). Safety and compliance were assessed within 3 days after eradication. Urea breath test was performed at 4-8 weeks after eradication to evaluate outcome. We used a noninferiority test to compare the eradication rates of the two groups. The intergroup differences were evaluated using Pearson chi-squared or Fisher's exact test for categorical variables and Student's t -test for continuous variables. RESULTS: As for the eradication rates of minocycline- and tetracycline-containing BQT, the results of both intention-to-treat (ITT) and per-protocol (PP) analyses showed that the difference rate of lower limit of 95% confidence interval (CI) was >-10.0% (ITT analysis: 181/217 [83.4%] vs . 180/217 [82.9%], with a rate difference of 0.5% [-6.9% to 7.9%]; PP analysis: 177/193 [91.7%] vs . 176/191 [92.1%], with a rate difference of -0.4% [-5.6% to 6.4%]). Except for dizziness more common (35/215 [16.3%] vs . 13/214 [6.1%], P = 0.001) in minocycline-containing therapy groups, the incidences of adverse events (75/215 [34.9%] vs . 88/214 [41.1%]) and compliance (195/215 [90.7%] vs . 192/214 [89.7%]) were similar between the two groups. CONCLUSION: The eradication efficacy of minocycline-containing BQT was noninferior to tetracycline-containing BQT as first-line regimen for H . pylori eradication with similar safety and compliance.

Objective To investigate the molecular mechanism of taurine regulating the polarization of M2 macrophages by mitophagy. Methods THP-1 cells were divided into four groups: M0 group (THP-1 cells were treated by 100 nmol/L phorbol myristate ester for 48 hours to polarize into M0), M2 group (THP-1 cells were induced to polarize into M2 macrophages by 20 ng/mL interferon-4 (IL-4) for 48 hours), M2 combined with taurine groups (added with 40 or 80 mmol/L taurine on the basis of M2 macrophages). The mRNA expression of mannose receptor C type 1(MRC-1), C-C motif chemokine ligand 22(CCL22) and dendritic cell-specific ICAM-3 grabbing non-integrin (CD209) in M2 macrophages were detected by quantitative real-time PCR. Mitochondrial and lysosome probes were used to detect the number of mitochondria and lysosomes by multifunction microplate reader and confocal laser scanning microscope. The level of mitochondrial membrane potential (MMP) was detected by JC-1 MMP assay kit. The expression of mitophagy-related proteins PTEN-induced putative kinase 1 (PINK1) and microtubule-associated protein 1 light chain 3 (LC3) were detected by Western blot analysis. Results Compared with M0 group, the expression of MRC-1, CCL22, CD209 and PINK1, the number of mitochondria and the level of MMP in M2 group were significantly increased, whereas the number of lysosomes and LC3II/LC3I ratio were decreased. Compared with M2 group, the expressions of MRC-1, CCL22 and CD209, the number of mitochondria and the level of MMP in M2 combined with taurine group dropped significantly while the number of lysosomes was found increased, and the protein expression of PINK1 and LC3II/LC3I ratio were also increased. Conclusions The polarization of M2 macrophages is regulated by taurine to prevent excessive polarization via reducing the level of MMP, improving the level of mitophagy, reducing the number of mitochondria, and inhibiting the mRNA expression of polarization markers in M2 macrophages.
