Objective To systematically review and quantify the content and structure of the non-accompanied wards policy texts at the provincial level in China from the perspective of policy tools,providing references and insights for optimizing and implementing future policies.Methods Using the policy analysis tools as framework,it applies content ana lysis to construct a two-dimensional analytical framework with the X-dimension and Y-dimension.A total of 19 policy texts related to non-accompanied ward issued by provincial governments in China from January 2000 to August 2024 were coded and analyzed.Results A total of 141 entries were coded.In the X-dimension,supply-oriented,demand-oriented,and environment-oriented policy tools accounted for 21.28%,19.86%,and 58.86%,respectively,indicating a greater reliance on environmental-oriented policy tools;In the Y-dimension,policies from the"12th Five-Year Plan"(16.31%),"13th Five-Year Plan"(14.89%),and"14th Five-Year Plan"(68.80%)phases were analyzed.The number of policies in the"14th Five-Year Plan"phase was the highest among the three periods.Conclusion The policy framework for non-accompanied wards in China is still in its initial exploration phase and has room for improvement.It is recommended that future policies optimize the use of policy tools,strengthen coordination among them,and support the development of non-accompanied wards.

Objective:To investigate the status of work-related musculoskeletal disorders (WMSDs) in male large-scale mechanical maintenance workers, and to explore the relationship between WMSDs and thyroid indexes.Methods:From April to July 2022, male front-line maintenance workers in a large-scale mechanical maintenance enterprise who participated in occupational health examination were selected as the study subjects ( n=2036). The occurrence of WMSDs was investigated by questionnaire. The levels of triiodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH) in serum were detected. χ2 test, t-test and Mann-Whitney U test were used to detect thyroid diseases and hormone levels of workers in WMSDs group and non-WMSDs group, and binary logistic regression model was used to analyze the relationship between thyroid disease, T3, T4, TSH and WMSDs. Results:The incidence of WMSDs among the male large-scale mechanical maintenance workers was 73.18% (1490/2036). The rate of thyroid disease in WMSDs group was higher than that in non-WMSDs group [8.26% (123/1490) vs. 4.95% (27/546), χ 2=6.42, P=0.011], and the TSH value was lower than that in non-WMSDs group[1.66 (1.23, 2.26) μIU/ml vs. 1.75 (1.30, 2.42) μIU/ml, Z=-2.40, P=0.019]. There were no significant differences in the levels of T3, T4 and abnormal levels of 3 hormones between the two groups ( P>0.05). After accounting for individual and occupational factors, workers with thyroid disease had an increased risk of WMSDs ( OR=1.656, 95% CI: 1.072-2.559, P=0.023), while workers with increased TSH had a decreased risk of WMSDs ( OR=0.897, 95% CI: 0.823-0.977, P=0.013) . Conclusion:The incidence of WMSDs in male workers of large-scale mechanical maintenance is high, and its incidence may be related to thyroid index. Thyroid disease may be a risk factor for WMSDs, and increased TSH may be a protective factor for WMSDs.

Objective To investigate the efficacy of voriconazole in the treatment of pulmonary tuberculosis complicated with chronic pulmonary aspergillosis(CPA)based on CYP2C19 gene polymorphism detection and examine the factors affecting the efficacy for improving targeted therapy in clinical practice.Methods A total of 207 patients with pulmonary tuberculosis complicated with CPA treated in the Third People's Hospital of Kunming from December 2018 to November 2022 were randomly assigned to an observation group(105 cases)or a control group(102 cases).The patients in the control group received standard voriconazole treatment,while the patients in the observation group had their voriconazole regimen tailored based on CYP2C19 genotyping results.Plasma drug concentration levels,efficacy,and safety were compared between the two groups and in terms of CYP2C19 genotypes.Logistic regression analysis was used to identify the factors affecting treatment efficacy.Results The observation group showed significantly higher plasma voriconazole concentrations and overall antifungal efficacy compared to the control group(P＜0.05).In the observation group,CYP2C19 genotyping identified 37 extensive metabolizers(EM),47 intermediate metabolizers(IM),and 21 poor metabolizers(PM).Plasma concentration of voriconazole did not show significant difference between EM and IM(P＞0.05),but both PM and IM were associated with significantly lower plasma concentration of voriconazole than PM(P＜0.05).The clinical efficacy rate was 100％for PM,91.5％for IM,and 83.8％for EM(P＜0.05).The incidence of adverse events did not show significant difference among the three genotypes(P＞0.05).Logistic regression analysis revealed that lung cavitation,hypoalbuminemia,and agranulosis were significantly correlated with therapeutic efficacy(P＜0.05).Conclusions CYP2C19 gene polymorphism detection is valuable in clinical practice.It can inform anti-aspergillus therapy with voriconazole to effectively improve symptoms and clinical efficacy in patients with pulmonary tuberculosis complicated with CPA.Meanwhile,clinicians should be aware of the factors such as hypoproteinemia,agranulocytosis,and lung cavitation that may affect the efficacy of voriconazole.

Objective To explore the mechanism of Tongdu Xingshen acupuncture,the clinical efficacy,systemic inflammatory response,blood-brain barrier and intestinal flora in patients with cognitive impairment after ischemic stroke(IS)were studied.Methods Thirty patients(3 cases shedding)with cognitive impairment after IS were included as the disease group,including patients before treatment as the disease group,patients after Tongdu Xingshen acupuncture treatment as the electroacupuncture group,and 30 healthy controls(3 cases shedding)were included as the healthy group.In the electroacupuncture group,on the basis of the basic treatment,Tongdu Xingshen acupuncture was applied,which was 30 min each time,once a day for 14 days.The MMSE,MoCA and MBI scores of the three groups were observed.The fecal and serum samples from all study subjects were collected,and 16S rDNA sequencing technology and ELISA were used to detect the changes of proinflammatory factors IL-6,IL-1β,TNF-α and S100β in serum in intestinal flora and feces.Results Compared with the healthy group,the MMSE,MoCA,and MBI score of patients in the disease group decreased significantly(P<0.05),serum proinflammatory factors and S100β protein content increased significantly(P<0.05),and the Shannon index(P<0.01)and Simpson index(P<0.001)increased significantly.Compared with the disease group,the MMSE,MoCA,and MBI score of the EA group increased significantly(P<0.05),the serum levels of proinflammatory factors and S100β decreased significantly(P<0.05),Shannon index and Simpson index decreased(P>0.05).The dominant bacterial flora in the healthy group mainly included Bacteroides,Bifidobacterium,Bacteroides,Faecalibacterium,Bifidobacteriaceae,Ruminococcaceae,and Bacteroides and other beneficial bacteria(P<0.05).The dominant flora in the disease group included Proteobacteria,Enterobacteriaceae,Escherichia,Klebsiella and other opportunistic bacteria(P<0.05),while the dominant flora in the EA group was consistent with the healthy group,the relative abundance of beneficial bacteria increased significantly(P<0.05),and the relative abundance of opportunistic bacteria decreased significantly(P<0.05).Spearman correlation analysis found that beneficial bacteria were positively correlated with clinical efficacy related indicators,but with serum proinflammatory factors and the content of S100β was negatively correlated.Conclusion Tongdu Xingshen acupuncture can regulate the diversity of intestinal flora to increase the abundance of Bacteroides,Bifidobacterium,Faecalibacterium,and other beneficial bacteria,regulate the intestinal microecological balance,Thereby regulating systemic inflammation and blood-brain barrier function,which plays a role in improving cognitive function.

Objective To investigate the changes of macrophages and hemophagocytes in bone marrow smears of patients with multiple myeloma(MM)before and after chemotherapy and their correlation with clinical prognostic value.Methods A total of 300 MM patients treated in Liaocheng Second People's Hospital Affiliated to Shandong First Medical University from June 2018 to June 2023 were selected as the study objects.All patients received at least 3 courses of chemotherapy and were divided into the remission group(n=214)and the non-remission group(n=86)according to the clinical effect.Immunoglobulin(Ig)A,IgG,CD3+,CD4+,CD8+,interleukin(IL-2),IL-4,IL-6,IL-17,tumor necrosis factor(TNF)-α,transforming growth factor(TGF)-β,macrophages and hemophagocytes were detected in the two groups and compared between the two groups.COX regression was used to analyze the relationship between immunological indexes and non-remission of chemotherapy.The relationship between macrophages and hemophagocytes and non-remission of chemotherapy was analyzed by restricted cubic spline.The multiplicative interaction of macrophages and hemophagocytes on non-remission of chemotherapy was analyzed using an unconditioned Logistic regression model,and the additive interaction was analyzed using the interaction calculation table.Receiver operating characteristic(ROC)curve analysis of macrophages and hemophagocytes alone or in combination to determine the value of chemotherapy non-remission.Results The overall response rate(ORR)and non-response rate(NRR)of MM patients were 71.33%and 28.67%respectively.Compared with before treatment,IgA,IgG,CD8+,IL-6,IL-17,TNF-α,TGF-β,macrophages and hemophagocytes were significantly decreased in both groups after treatment(tslow=9.252～61.177,tnot slow=4.057～35.797).CD3+,CD4+,CD4+/CD8+,IL-2 and IL-4 were significantly increased(tslow=9.706～33.940,tnot slow=4.227～16.167),and the differences were statistically significant(all P<0.05).After treatment,compared with the remission group,IgA,IgG,CD8+,IL-6,IL-17,TNF-α,TGF-β,macrophages and hemophagocytes in the non-remission group were significantly higher than those in remission group(t=3.362～30.028),CD3+,CD4+,CD4+/CD8+,IL-2 and IL-4 were significantly lower than those in remission group(t=3.736～13.998).and the differences were statistically significant(all P＜0.05).After adjusting the influence of other factors by COX regression,the trend test of macrophages and hemophagocytes was still statistically significant the trend test of macrophages and hemophagocytes was still statistically significant(P<0.05).Patients with≥5 macrophages/tablet and≥3 hemophagocytes/tablet had a significantly increased risk of non-remission from chemotherapy(P<0.05).There were additive(OR=6.157,95%CI:3.768～12.978)and multiplicative(OR=5.648,95%CI:1.035～17.492)interactions between macrophages and hemophagocytes in the non-remission of chemotherapy.Compared with the single judgment of macrophages and hemophagocytes,the combination of the two has the highest accuracy in determining chemotherapy non-remission(P＜0.05).Conclusion Macrophages and hemophagocytic cells in MM patients after chemotherapy are significantly lower than those before chemotherapy,with≥5 macrophages/tablet and≥3 hemocyte phages/tablet,indicating that the risk of non-remission in patients with chemotherapy increased significantly,and the combination of the two can accurately judge the clinical efficacy.

Objective To compare the safety and feasibility of laparoscopic total extraperitoneal herniorrhaphy(TEP)and laparoscopic transabdominal preperitoneal prosthesis(TAPP)in the treatment of inguinal hernia.Methods This study adopts retrospective cohort study method.The clinical data of 107 cases of inguinal hernia treated by laparoscopic inguinal hernia repair in Minimally Invasive Surgery,Hernia and Abdominal Surgery of Xinjiang Uygur Autonomous Region People's Hospital from January 2014 to May 2024 were collected.According to the surgical methods,they were divided into two groups:38 cases in the TEP group and 69 cases in the TAPP group.Compare and analyze the differences between TEP group and TAPP group in basic situation,operation,postoperative recovery,operation cost,postoperative inflammation index,liver and kidney function evaluation index.Results The time to start getting out of bed after surgery in the TEP group and the TAPP group was(14.55±1.95)h and(16.12±3.11)h,respectively(P=0.006).The recovery times of gastrointestinal function were(22.11±4.94)h and(24.61±4.88)h respectively(P=0.013).There was a statistically significant difference between the two groups(P＜0.05).There was no significant difference in postoperative inflammation,liver and kidney function,postoperative complications and recurrence(P＞0.05).Conclusion Both TEP and TAPP are safe and feasible in the treatment of inguinal hernia.After TEP,the time to get out of bed was shorter and the intestinal function recovered faster.

Background/Aims: Dexamethasone (DEX) is a widely used exogenous therapeutic glucocorticoid in clinical settings. Its long-term use leads to many side effects. However, its effect on metabolic disorders in individuals on a high-fat diet (HFD) remains poorly understood. Methods: In this study, HFD-fed mice were intraperitoneally injected with DEX 2.5 mg/kg/day for 30 days. Lipid metabolism, adipocyte proliferation, and inflammation were assayed using typical approaches. Results: DEX increased the epididymal fat index and epididymal adipocyte size in HFD-fed mice. The number of epididymal adipocytes with diameters > 70 μm accounted for 0.5% of the cells in the control group, 30% of the cells in the DEX group, 19% of the cells in the HFD group, and 38% of all the cells in the D+H group. Adipocyte proliferation in the D+H group was inhibited by DEX treatment. Adipocyte enlargement in the D+H group was associated with increased the lipid accumulation but not the adipocyte proliferation. In contrast, the liver triglyceride and total cholesterol levels and their metabolism were downregulated by the same treatment, indicating the therapeutic potential of DEX for nonalcoholic fatty liver disease. Conclusions DEX synergizes with HFD to promote lipid deposition in adipose tissues. A high risk of obesity development in patients receiving HFD and DEX treatment is suggested.

Background The job content of aircraft maintenance workers is complex, with high intensity and high requirements, and they are prone to work-related musculoskeletal disorders (WMSDs), but related research is relatively rare. Objective To investigate the positive rate of WMSDs among aircraft maintenance workers, evaluate ergonomic load, and analyze the risk factors of WMSDs. Methods We used a self-compiled questionnaire for WMSDs and the Quick Exposure Checklist (QEC) to investigate the basic situation, positive rate of WMSDs, and the ergonomic load of 2271 male maintenance workers in 6 departments of an aircraft maintenance company, including airline maintenance, overall overhaul, accessory/landing gear overhaul, engine overhaul, product customization, and power assist. We used a logistic regression model to analyze the risk factors of WMSDs in the neck, shoulder, hand/wrist, and lower back. Results The positive rate of WMSDs in the past 12 months was 70.4% (1598/2271) and the positive rate of WMSDs in different body parts ranged from 6.6% to 49.5%, with the top three parts of lower back, neck, and knee, respectively. There were statistically significant differences in the positive rate among different departments (P<0.05). The average QEC scores for neck, hand/wrist, and back (static) were moderate, while those for shoulder and back (dynamic) were high, and the body part specific positive rate of WMSDs increased with the increase of ergonomic load level. Working years (5-<10 years, ≥20 years), working with back flexed or twisted or side bent (moderately, excessively), high maximum force level exerted by one hand, and feeling difficult (sometimes, often) and stressful (moderately, very) while working were associated with higher risks of lower back pain (OR=1.486, 1.505; 2.151, 3.769; 1.637; 2.110, 2.407; 1.637, 1.794; P<0.05). Working years (15-<20 years, ≥20 years), working with head/neck bent or twisted (occasionally, continuously), feeling difficult (sometimes) and stressful (very) while working were associated with higher risks of neck pain (OR=1.731, 1.586; 3.732, 8.341; 1.633; 1.696; P<0.05). Working years (15-<20 years, ≥20 years), working with hands in a high position (at shoulder or above), very frequent shoulder/arm movements, feeling difficult (sometimes, often) and stressful (moderately, very) while working were associated with higher risks of shoulder pain (OR=1.587, 1.709; 1.299; 1.521; 1.643, 2.239; 1.659, 1.977; P<0.05). Working with wrist at deviated or bent angle, high repetition of similar movements, feeling difficult (sometimes, often) and stressful (moderately, very) while working were associated with higher risks of hand/wrist pain (OR=1.692; 1.670; 1.827, 2.884; 2.190, 2.625; P <0.05) . Physical exercise after work (≥3 times·week⁻¹) was associated with a lower risk of neck pain (OR=0.582, P<0.05). Shift workers were at a lower risk of shoulder pain and hand/wrist pain (OR=0.737 and 0.554, P<0.05). Conclusion The high positive rate of WMSDs symptoms among aircraft maintenance workers is related to individual, occupational ergonomic, and psychological factors, and active prevention and intervention should be taken.
