Objective: This study aims to explore the association between oral lichen planus (OLP) and Hashimoto’s thyroiditis (HT) and its anti-thyroid antibodies to provide clinical evidence for thyroid disease screening in patients with OLP. Methods: This study was approved by the institutional ethics committee. A total of 125 clinically and histopathologically confirmed patients with OLP were enrolled as the case group, and they were matched with 125 non-OLP controls based on sex and age. Demographic data (gender, age, lesion type, and disease duration) were collected from both groups. Serum levels of thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb) were measured to analyze their associations with sex, age, lesion type, and disease duration in patients with OLP. Result: The prevalence of HT in patients with OLP was 31.20%, significantly higher than that in the control group (9.60%) (χ2=18.504, P<0.001). The prevalence of HT in female patients with OLP (39.13%) was significantly higher than that in male patients (9.09%)（χ2=10.93，P<0.001）. The positivity rate of thyroid peroxidase antibodies (TPOAb) in patients with OLP (17.6%) was significantly higher than in the control group (4.0%) (χ2=10.989, P<0.001). The TPOAb positivity rate was significantly higher in female patients (22.83%) than in male patients (3.03%) (χ2=5.210, P=0.014). There was no statistically significant difference in the positivity rate of TgAb between patients with OLP (7.2%) and the control group (3.2%) (P>0.05). Patients with erosive lesions had a significantly higher TPOAb positivity rate (25.0%, 17/68) compared to those with non-erosive lesions (8.77%, 5/57), and the difference was statistically significant (χ2=4.831, P=0.028). Logistic regression analysis revealed that female patients with OLP had an 8.935-fold higher risk of being TPOAb positive compared to males (OR=8.935, 95%CI: 1.134-70.388, P=0.038). Patients with erosive OLP lesions had a 3.199-fold higher risk of TPOAb positivity compared to those with non-erosive lesions (OR=3.199, 95%CI: 1.064-9.618, P=0.038). Conclusion The prevalence of HT is higher in patients with OLP, with higher positivity rates of anti-thyroid antibodies observed in female patients and those with erosive OLP lesions. This suggests that thyroid disease screening should be incorporated into the clinical management of patients with OLP, especially for women and patients who present with erosive lesions.

Objective To investigate the clinical efficacy of β-blockers in older patients with hypertension combined with vascular dementia.Methods A total of 152 older patients with hypertension combined with vascular dementia who were admitted to Shanxi Provincial Fenyang Hospital between January 2022 and October 2024 were enrolled.The participants were randomly assigned to either the study group or the control group(76 patients each)using the randomized numerical table method.Both groups received conventional treatment,and the study group received metoprolol for 5 weeks in addition to the conventional treatment.Primary outcome indicators,including changes in systolic blood pressure(SBP)and diastolic blood pressure(DBP)before and after treatment,were examined.Additionally,comparison was made to examine the intergroup difference in serological markers,including high-sensitivity C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α),interleukin(IL)-6,IL-8,matrix metalloproteinase 9(MMP-9),homocysteine(Hcy),and superoxide dismutase(SOD)levels,and the scores for intelligence,cognitive,and behavioral assessments.Adverse reactions were recorded.Results After treatment,the study group showed reduced SBP from(146.90±7.35)mmHg(1 mmHg=0.133 kPa)to(120.00±6.03)mmHg and reduced DBP from(90.24±5.97)mmHg to(77.23±6.81)mmHg.The reduction in blood pressure in the study group became more significantly when compared with that of the control group,with intergroup difference in SBP reduction being-8.54 mmHg(P<0.001)and intergroup difference in DBP reduction being-10.80 mmHg(P<0.001).Patients in the 2 groups showed statistically significant differences in the levels of hs-CRP,TNF-α,IL-6,IL-8,MMP-9,and Hcy,and in their cognitive and behavioral scores(P<0.05).No statistically significant differences were found in pulse pressure,von Willebrand factor(vWF)levels,or intelligence scores before and after treatment(P>0.05).The main adverse reactions in the study group were central nervous system reactions(22.37%)and withdrawal syndrome(17.11%).Conclusion The β-blocker metoprolol effectively controlled blood pressure,significantly reduced levels of pro-inflammatory factors and specific vascular injury markers,and improved cognitive function and behavioral symptoms in older patients with hypertension combined with vascular dementia,suggesting its therapeutic efficacy for this condition.However,attention should be paid to its associated adverse reactions.

ObjectiveTo evaluate the efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) for muscle atrophy in patients with immobilization after surgical fixation of foot and ankle fractures.MethodsThis was a two-arm randomized controlled trial wherein 80 patients were recruited and divided into control (n = 40) and intervention (n = 40) groups. The control group received conventional orthopedic treatment, whereas the intervention group received TEAS and conventional treatment. The intervention group received TEAS 3 times a week for 30 min each time for 8 weeks. The primary outcomes were muscle thickness (MT) and cross-sectional area (CSA) of the rectus femoris and gastrocnemius muscles, whereas the secondary outcome measure was echo intensity (EI). Data were collected before the fixation operations (baseline assessment) and 4 and 8 weeks after intervention.ResultsCompared with baseline, the MT and CSA were reduced in both groups by the end of treatment, whereas EI increased in both groups. At week 4, the reduction in the rectus femoris CSA in the intervention group was significantly lower than that in the control group (P = .02); however, the between-group differences in the MT and EI (all P .05) were not significant. No serious adverse events were observed in either group.ConclusionOur study showed that TEAS can improve muscle atrophy by attenuating the decline in the muscle CSA. Because this was only a pilot trial, subsequent studies will need longer follow-ups and larger sample sizes.

Background and objective Lung cancer is the malignant tumor with the highest incidence rate and the heaviest disease burden in China.In recent years,lung cancer has shown a high incidence trend,seriously affecting the health of the population.In this paper,we analyze the characteristics of lung cancer incidence in 2019 and the trend of incidence rate from 2010-2019 in the tumor registration area of Gansu province,in order to provide a reference basis for the development of lung cancer prevention and control strategies in Gansu province.Methods By analyzing the cases of lung cancer incidence in the tumor registration area of Gansu province in 2019,we calculated the incidence rate,medium incidence rate,world in-cidence rate and other related indexes;we used Joinpoint to calculate the annual percentage change(APC)for trend analysis.Results In 2019,a total of 3757 new cases of lung cancer were reported in Gansu province,accounting for 14.96%of all new malignant tumors.The incidence rate,medium incidence rate and world incidence rate and world rate of lung cancer were 40.52/105,25.78/105,25.86/105;and the cumulative rate of 0-74 years old,and the truncation rate of 35-64 years old were 3.23%,40.03/105,respectively.The incidence of lung cancer rises with age,and is high in the age group of 40 years and above,and the incidence peaks in the male and female populations in the group of 75 years and above,and the group of 80 years and above,respectively.The crude incidence rate of lung cancer in the tumor registration area of Gansu province from 2010-2019 showed an overall increasing trend,and the rate of increase was relatively fast,with an APC 5.39%(P<0.05);Separately,accord-ing to gender,urban and rural areas,the incidence of lung cancer in all populations showed an increasing trend,and the APC of male,female,urban and rural populations were 4.98%,6.39%,6.26%,and 4.64%,respectively(all P<0.05).According to the trend analysis of lung cancer incidence rate by age group,only lung cancer incidence in the age group of 65 years and above increased at an annual average rate of 4.15%(P<0.05).Conclusion The incidence rate of lung cancer in the tumor registration area of Gansu province from 2010 to 2019 shows a rising trend year by year,and there are differences in the incidence of lung cancer in people of different genders,regions and age groups,so comprehensive prevention and control work should be carried out for the key populations of lung cancer incidence.

Objective To investigate the performance of using lung dynamic compliance(Cdyn)and airway resistance(RAW)levels to predict lung infection in elderly esophageal cancer patients who have undergone radiotherapy.Methods A total of 298 elderly esophageal cancer patients who received radiotherapy at Shanxi Fenyang Hospital between October 2017 and July 2022 were retrospectively enrolled and their clinical data were collected.The patients were divided into an infection group(124 cases)and a non-infection group(174 cases)according to their status of lung infection.Then,in the infection group,CURB-65 score was used to assess the severity of the patients'lung infection and the patients were further divided into subgroups accordingly,with 36 cases in the mild infection subgroup,58 cases in the moderate infection subgroup,and 30 cases in the severe infection subgroup.The levels of Cdyn,RAW,and infection indicators,including serum procalcitonin(PCT),interleukin-6(IL-6),and angiotensin Ⅱ(Ang Ⅱ),were measured in both groups of patients and the differences in the findings were compared between the infection and the non-infection groups and among patients with infection of varying degrees of severity.The correlation between Cdyn and RAW and the levels of PCT,IL-6,and Ang Ⅱ was analyzed.Receiver operating characteristic(ROC)curve was used to evaluate the performance of predicting infection with Cdyn and RAW.Results The Cdyn level of patients in the infection group was lower than that of patients in the non-infection group,while the RAW level of the infection group was higher than that of the non-infection group(P＜0.05).Among the infection subgroup,the level of Cdyn of the mild infection subgroup was higher than those of the moderate and severe infection subgroups,while the levels of RAW,PCT,IL-6,and Ang Ⅱ of the mild infection subgroup were lower than those of the moderate severe subgroups.The level of Cdyn of the moderate infection subgroup was higher than that of the severe infection subgroup,while the RAW,PCT,IL-6,and Ang Ⅱ levels of the moderate infection subgroup were lower than those of the severe infection subgroup,with all difference being statistically significant(P＜0.05).The Cdyn level of patients with lung infection was negatively correlated with PCT,IL-6,and Ang Ⅱ levels and the severity of infection(r=-0.501,-0.430,-0.367,and-0.484,respectively,P＜0.05),while RAW was positively correlated with PCT,IL-6,and Ang Ⅱ levels and the severity of infection(r=0.483,0.395,0.374,and 0.423,respectively,P＜0.05).The area under the curve(AUC)of Cdyn and RAW for predicting lung infection in elderly patients with esophageal cancer after radiotherapy were 0.898(95％confidence interval[CI]:0.857-0.930)and 0.823(95％CI:0.775-0.865),respectively,and the AUC of combined evaluation of Cdyn and RAW was 0.959(95％CI:0.930-0.979),which suggested that the predictive performance of combined evaluation was better than evaluation with Cdyn or RAW alone.Conclusion When elderly esophageal cancer patients develop lung infection after radiotherapy,their Cdyn level is decreased,while the levels of RAW,PCT,IL-6,and Ang Ⅱ are increased.In addition,the levels of Cdyn and RAW are correlated with the PCT,IL-6,and Ang Ⅱ levels.The combined use of Cdyn and RAW shows good performance for predicting lung infection in patients.

Objective To investigate the relationship between muscle mass reduction and quality of life in elderly lung cancer patients at the initial visit.Methods Totally 221 patients with non-small cell lung cancer undergoing chest and abdominal CT examination were included in this study at Fenyang Hospital in Shanxi Province.The Pearson's correlations of skeletal muscle index(SMI) and skeletal muscle radiodensity(SMD)with the disease stage,physical function,role of physical function,global quality of life,fatigue and dyspnea were analyzed.Results The average age of 221 patients was(70.2t9.0)years.The mean SMI for men and women was(46.7± 7.8)cm2/m2 and(39.4 ±6.4) cm2/m2 respectively.Multivariate linear regression analysis showed that SMI affected the body function,role of physical function,global quality of life,and fatigue dimension(all P ＜ 0.05),and SMD affected the physical function of life quality and dyspnea dimension(P ＜0.05).SMI was related to the physical function and role of physical function(men:r =0.287 and 0.245,P =0.001 and 0.006;women:r=0.296 and 0.395,P =0.004 and 0.000).In male patients,SMO was also associated with low global quality of life and fatigue(r=0.191 and-0.198,P =0.032 and 0.026).The above relationships did not change even after adjusting for the effect of age and disease stages.Low SMD was associated with low physical function and dyspnea in both men and women(men:r =0.287 and 0.245,P=0.037 and 0.049;women.:r=0.281 and-0.262,P=0.006 and 0.010),and SMD was associated with dyspnea only in women even after adjusting for age and disease stages.A correlation between SMI and the disease stage was found in both men and women(male:r =-0.266,P=0.003;female:r=-0.223,P=0.005).Conclusions Changes in muscle mass may affect the physical function,role of physical function and global quality of life in elderly patients with non-small cell lung cancer.

Objective To investigate the distribution and changing resistance proifle ofSalmonella isolates in hospitals across China during the period from January 2005 to December 2014.Methods Seventeen general hospitals and two children’s hospitals were involved in this program. Antimicrobial susceptibility testing was carried out by means of a unified protocol using Kirby-Bauer method or MIC determination. The results were analyzed according to CLSI 2014 breakpoints.Results The proportion ofSalmonella isolates increased with time from 0.2% in 2005 to 0.7% in 2014. A total of 3 478Salmonella strains were collected from 19 hospitals. The proportion ofSalmonella typhimurium andSalmonella enteritidis was 27.4% and 24.4%, respectively. During the 10-year period, theSalmonella strains showed highest resistance rate to ampicillin (33.3%-64.8%), but low resistance to cefoperazone-sulbactam (0-5.3%) and ciprofloxacin (2.4%-14.3%).S. typhimurium showed higher resistance rate thanS. typhi,S. paratyphi andS. enteritidis. About 76.8% and 50.5% ofS. typhimurium were resistant to ampicillin and trimethoprim-sulfamethoxazole. The average prevalence of multi-drug resistantSalmonellawas 3.9% in the ten-year period, the highest (7.5%) was in 2005, the lowest (1.5%) in 2013.Conclusions During the period from 2004 to 2015, majority of theSalmonella isolates in hospitals across China wasS. typhimurium andS. enteritidis. Ampicillin and trimethoprim-sulfamethoxazole are no longer appropriate for empirical treatment ofS. typhimurium infection due to high resistance rate.Salmonella isolates are relatively more susceptible to third-generation cephalosporins and quinolones. Ongoing monitoring is necessary to identify multi-drug resistant strains ofSalmonella.
