Objective: To investigate the implementation and evaluate the effectiveness of health management services for patients with type 2 diabetes mellitus (T2DM) in Urumqi City from 2017 to 2021, so as to provide the reference for enhancing T2DM patients management. Methods: Data on the rates of record establishment, health management and standardized management for T2DM patients, and blood glucose control rate in managed patients in Urumqi City from 2017 to 2021 were collected through the quarterly reports on basic public health service management from the Weining Health Platform System. The trends in the four management indicators, and the differences between urban and rural areas were analyzed. Results: The rates of record establishment, health management and blood glucose control rate in managed patients in Urumqi City were 46.94%, 38.37% and 59.92%, respectively, showing upward trends from 2017 to 2021 (all P<0.05). The rate of standardized management was 75.89%, showing a downward trend (P<0.05). The rate of record establishment was higher in urban areas than in rural areas (47.76% vs. 40.56%, P<0.05). The rates of standardized management and blood glucose control in managed patients were lower in urban areas than in rural areas (75.18% vs. 81.46%, 58.93% vs. 67.64%, both P<0.05). The rate of health management was 38.39% in urban areas and 38.24% in rural areas, with no statistically significant difference (P>0.05). The trends in the rates of record establishment, health management and standardized management in both urban and rural areas were consistent with those in the overall population. Conclusions From 2017 to 2021, the rates of record establishment, health management and blood glucose control in managed patients in Urumqi City showed upward trends, while the rate of standardized management exhibited a downward trend. There were urban-rural differences in the rates of record establishment, standardized management and blood glucose control in managed patients.

Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.

Objective To analyze the epidemiological characteristics and trends of type 2 diabetes death in Urumqi from 2017 to 2022, and to provide a theoretical basis for formulating diabetes prevention and control policies. Methods The crude mortality rate, standardized mortality rate, annual percentage change (APC), dynamic series and other indicators of 2 177 death data of type 2 diabetes collected in Urumqi from 2017 to 2022 were statistically analyzed. At the same time, the Autoregressive Integrated Moving Average (ARIMA) prediction model was used to establish a model based on the death data from January 1, 2017 to June 30, 2022, to predict the monthly number of type 2 diabetes death in the second half of 2022, and compare it with the actual value to evaluate the model fitting effect. Results From 2017 to 2022, the mortality rate of type 2 diabetes in Urumqi reached 13.46/100 000, and the standardized mortality rate was 11.78/100 000. There was a significant difference in APC results for male mortality (P<0.05). The mortality rate of type 2 diabetes increased with age, and the mortality rate was higher in men than in women before the age of 70, and conversely, female mortality was higher than male. Retirees, married people, and people with junior high school education or below had higher mortality rates than others. The results of the standardized mortality dynamic series showed that the average rate of development in men was higher than that in the general population and women. By establishing the optimal ARIMA (0,1,1) prediction model, the model fit was qualified, while the accuracy would need to be improved. Conclusion From 2017 to 2022, the mortality rate of type 2 diabetes in Urumqi has an increasing trend. In order to realize the Healthy China Action, it is necessary to focus on health publicity and education for the elderly in the jurisdiction, prevent the occurrence of type 2 diabetes comorbidities, and reduce the mortality rate of type 2 diabetes.

Objective: To analyze the current status and related factors of comorbidity of myopia, obesity, and depression symptoms among middle school students in Beijing, so as to provide a basis for comprehensive public health interventions for common diseases. Methods: Through stratified cluster random sampling in October 2022, a total of 11 262 junior high school, senior high school, and vocational high school students in 16 districts of Beijing were surveyed with self administered questionnaires, physical examinations and visual acuity examinations. The χ 2 test and binary Logistic regression model were used to analyze group differences in the comorbidity of myopia, obesity and depression symptoms and factors influencing the comorbidity. Stratified analysis was applied to analyze the associations between health risk behaviors and the comorbidity. Results: The detection rate of comorbidity of myopia, obesity, and depression symptoms among middle school students in Beijing was 3.35%, the comorbidity rate among vocational high school students (4.61%) was higher than that in junior high school students (2.80%) and senior high school students (3.41%). The comorbidity rate was higher among students in suburban areas (3.66%) than that in urban areas (2.92%), and the differences was statistically significant ( χ 2=15.02, 4.63, P <0.05). Binary Logistic regression analyses indicated that middle school students with poor dietary behaviors ( OR =1.59) and excessive screen time ( OR =1.70) were associated with elevated risk of comorbidity of myopia, obesity, and depression symptoms. Both boys and girls with poor dietary behaviors ( OR =1.63, 1.69) and excessive screen time ( OR =1.45, 2.23) had elevated likelihood of comorbidity of myopia, obesity and depression symptoms. Students in junior high school and senior high school with poor dietary behaviors ( OR =2.16, 1.47) and excessive screen time ( OR =2.20, 1.63 ) had elevated likelihood of comorbidity of myopia, obesity, and depression symptoms ( P <0.05). Conclusions The current status of comorbidity of myopia, obesity, and depression symptoms among middle school students in Beijing is concerning. Schools and parents should work together to guide students to develop healthy behaviors such as balanced diet and moderate video, in order to achieve the goal of controlling myopia, obesity and depression symptoms.

Objective: To investigate the comorbidity of screening myopia and scoliosis among primary and secondary school students in Beijing from 2019 to 2022 and its influencing factors, in order to provide new ideas for comprehensive prevention and control of myopia and scoliosis in children and adolescents. Methods: From 2019 to 2022, 34 923, 34 321, 36 008 and 35 598 primary and secondary school students in Beijing were selected by stratified cluster random sampling method, and visual acuity examination, scoliosis examination and questionnaire survey were conducted on them. Chisquare test was used to analyze the intergroup differences between screening myopia and scoliosis among primary and secondary school students, and the correlation factors between screening myopia and scoliosis were analyzed by multivariate Logistic regression. Results: From 2019 to 2022, the prevalence of screening myopia increased by year,while scoliosis decreased by year, and the comorbidity rate in 2022 (0.69%) decreased by 1.62% compared with 2019 (2.31%). In 2022, screening myopia with scoliosis rates (0.98%) than urban suburbs (0.50%), high school students (1.65%) >professional high school students (1.21%) >junior middle school students (0.76%) >primary school students (0.22%) (χ2=28.97, 153.55, P<0.01). The results of multivariate Logistic analysis found that insufficient sleep time and parents did not limit the use of electronic screen time were the risk factors for screening myopia and scoliosis [OR(95%CI)=1.59(1.20-2.12), 1.34(1.02-1.76), P<0.05]. Teachers often or always remind that reading and writing posture and one hour or more of moderateintensity physical activity every day were protective factors for screening myopia and scoliosis [OR(95%CI)=0.70(0.52-0.96), 0.56(0.34-0.92), P<0.05]. Conclusions The comorbidity of acadmic screening myopia and scdiosis is not optimistic in Beijing. Attention should be paid to the reading and writing posture and related behavioral habits of children and adolescents, and ensure that children in each school section have sufficient sleep time, so as to prevent the occurrence and development of screening myopia and scoliosis.

Tumor immune microenvironment is an important microecology for tumor development, where tumor-associated macrophages are the most abundant immune cells in the tumor immune microenvironment, with high plasticity and heterogeneity. Under the regulation of various environmental factors, tumor-associated macrophages can differentiate into different subgroups. Though complex and variable, all these environmental factors ultimately regulate tumor-associated macrophages by influencing the temporal and spatial heterogeneity of these cells’ internal components, structure, and functions. Mitochondrion are important organelles, responsible for energy production, metabolism, and centers of multiple signal transduction. More and more studies have found that mitochondria can regulate cell functions through various mechanisms such as morphological change, metabolic reprogramming, intermediate metabolites or mitochondrial genetic material. Mitochondrial disorders are involved in many diseases and pathological processes. Here, we review the mechanisms by which mitochondria regulate the polarization of macrophages and thus reshape the tumor immune microenvironment. Further, we discuss and prospect the current status of macrophage mitochondria-related tumor immunotherapy.

Objective:To compare the positioning errors in tracing the body surface markers between radiotherapy placement with or without using the laser positioning coordination system in post-breast conservative surgery patients, and to verify the clinical value of the laser positioning coordination system.Methods:A total of 45 post-breast-conservative surgery patients who underwent radiotherapy in Department of Radiation Oncology of the Affiliated Hospital of Inner Mongolia Medical University from January 2022 to September 2023 were prospectively collected. In the experimental group 1 ( n=15), the initial version of the laser positioning coordination system was employed to trace the body surface markers. In the experimental group 2 ( n=15), the upgraded version of the laser positioning coordination system was adopted to draw the body surface markers. In the control group ( n=15), the body surface markers were traced with conventional approach. All patients were treated with spiral tomotherapy (TOMO), and the error values in the left and right directions ( X), head and foot directions ( Y), ventral and dorsal directions ( Z), and rotation angles (ROLL) before each radiotherapy were recorded. The differences in the positioning errors among the three groups were analyzed by t-test. Results:The positioning errors in the X, Y, Z directions and ROLL in the experimental group 1 were (3.10±2.43) mm, (4.36±3.45) mm, (2.29±2.49) mm and 0.95°±0.88°, and (2.88±2.28) mm, (3.58±2.95) mm, (2.40±2.54) mm, and 0.70°±0.70° in the experimental group 2, and (4.32±3.48) mm, (5.49±4.74) mm, (2.61±3.38) mm and 1.22°±1.16° in the control group, respectively. Statistical significance was observed in the differences of positioning errors in the X, Y directions and ROLL between the experimental group 1 and control group ( t=4.32, 2.89, 2.78, P < 0.001, =0.004, =0.006), respectively. Statistical significance was detected in the differences of positioning errors in the X, Y directions and ROLL between the experimental group 2 and control group ( t=5.20, 5.14, 5.82, all P<0.001). Statistical significance was noted in the differences of positioning errors in the Y direction and ROLL between the experimental group 1 and 2 ( t=2.58, 3.41, P=0.010, 0.001). Conclusion:The laser positioning coordination system-assisted tracing the body surface marking line can significantly reduce the positioning errors in the X and Y directions and ROLL, and the upgraded version of the laser positioning coordination system can further reduce the positioning errors in the Y direction and ROLL compared with the initial version, which is of high clinical application value.

Objective:To evaluate the efficacy of ultrasound-guided semispinalis capitis plane (SCP) block for treatment of occipital neuralgia (ON).Methods:This was a prospective study. Ninety patients of both sexes, aged 29-66 yr, suffering ON for 3 months-6 yr in Zibo Municipal Hospital from January 2022 to December 2023, were divided into 3 groups ( n=30 each) using a random number table method: combination of greater occipital nerve (GON) block and the third occipital nerve (TON) block group (group GT), SCP block via the medial head of semispinalis capitis muscle (SCM) group (group Sm), and SCP block via the space between obliquus capitis inferior and C 2, 3 facet joint (OCI-C 2, 3) group (group OC). In GT group, the analgesic and anti-inflammatory compound solution 2.5 ml was injected around GON in the SCM-OCI space at the C 2 level of the cervical vertebra and at the lateral surface of C 2, 3 facet joint. In Sm group, the analgesic and anti-inflammatory compound solution 5 ml was injected into the medial head of SCM at the level of C 1. In OC group, the analgesic and anti-inflammatory compound solution 5 ml was injected into the OCI-C 2, 3 space in the deep part of SCM. The Visual Analogue Scale (VAS) score and Pittsburgh Sleep Quality Index (PSQI) score were recorded before treatment (T 1) and at 1, 3, 7, 10 and 14 days after treatment (T 2-6), and then the rates of pain relief and improvement in sleep quality were calculated. The time spent in blocking, onset time of blocking, completion time of blocking, duration of block, and occurrence of adverse reactions within 24 h after block were recorded. Results:There were no significant differences in VAS scores and PSQI scores at T 1-3 and T 5-6 among the three groups ( P>0.05), and VAS and PSQI scores were significantly higher at T 4 in Sm group than in OC and GT groups ( P<0.05). Compared with GT group, the time spent in blocking was significantly shortened, the onset time and completion time of block was prolonged, and the duration of block was shortened in Sm group, and the time spent in blocking was significantly shortened, the onset time and completion time of block was shortened ( P<0.05), and no significant change was found in the duration of block in OC group ( P>0.05). No severe complications were observed in the three groups. Conclusions:Compared with the combination of GON and TON blocks, ultrasound-guided SCP block for treating ON is simple and highly safe, SCP block via the OCI-C 2, 3 space has rapid onset and long duration, leading to significant improvements in pain and sleep quality, and it can be used as the first-choice block method for treating ON.

Objective To explore the application value of low-flow rate and-contrast injection scheme for pulmonary artery computed tomography angiography(CTA)in the elderly patients.Methods Sixty elderly patients undergoing pulmonary artery CTA in some hospital from April 2020 to January 2023 were selected and divided into a control group(30 cases)and an experimental group(30 cases)according to the contrast agent injection schemes.A conventional contrast injection scheme was used for the control group,and an optimized contrast injection scheme with low flow rate and low contrast dose was designed for the experimental group.The two gorups were observed and subjectively scored in terms of the degree of pulmonary artery enhancement,the display of pulmonary artery trunks and branches and the sharpness of image vessel edges,and objectively evaluated for the degree of contrast sclerosis artifacts in the superior vena cava and the enhancement CT values of the pulmonary artery trunks and the left and the right pulmonary veins.The extravasation of the contrast agent was recorded for the patients in the 2 groups.SPSS 25.0 software was used for statistical analysis.Results The two groups had no significant differences in score pulmonary artery CTA image quality(P＞0.05);the experimental group had the socre of contrast sclerosis artifacts in the superior vena cava statistically lower than that of the control group(P＜0.05).The two groups had no obvious differences in the CT values of the pulmonary artery trunks and the left and the right pulmonary veins(P＞0.05).There were no patients with the extravasation of the contrast agent found in the experimental group,while there one case with severe extravasation and 4 cases with mild or moderate extravasation in the control group.Conclusion Low-flow rate and-contrast injection scheme for pulmonary artery CTA of the elderly patients contributes to avoiding contrast agent extrava-sation while ensuring image quality,enhancing patient experience and safety.[Chinese Medical Equipment Journal,2024,45(10):66-70]

Upon penetration into the host organism,the decapsulated larvae(intestinal infective stage 1 larvae)of Trichinella spiralis(T.spiralis)proceed to invade the host's small intestinal epithelial cells to continue their development,which is a critical step for T.spiralis infection and pathogenesis.Based on our prior research,the Ts-DNase Ⅱ-7 protein,which is present in the adult stage of T.spiralis,has a role in promoting the parasite's invasion of the intestinal epithelium.This is achieved by disrupting the integrity of the intestinal barrier,consequently promoting the parasitization of these cells in the host organism.Ts-DNase Ⅱ-7 can induce differential expression of various miRNAs,among which miR-142-5p has been reported to be involved in disrupting the intestinal barrier.Therefore,in this study,we investigated the mechanism by which Ts-DNase Ⅱ-7-induced miR-142-5p regulates intestinal epithelial cell barrier function by affecting target genes.The experiment was divided into Ts-DNase Ⅱ-7-treated group,miR-142-5p overexpression group(OE),miR-142-5p inhibition group(Inhibition),negative control group(NC)and control group(Control),lentiviral vectors for overexpression and suppression of miR-142-5p expression were used to infect human colorectal adenocarcinoma cells Caco-2 at an MOI of 80,and puromycin(8 mg/L)was used to screen cells to obtain cell lines that stably suppressed the expression of miR-142-5p and cell lines that miR-142-5p was overexpressed,cell transfection efficiency was assessed by fluorescence microscopy,and the relative expression of miR-142-5p was detected by RT-qPCR in each group of cells.The target gene Claudin-1(CLDN1)was predicted and validated using miR target prediction database,RT-qPCR,Western blot and dual luciferase assay.HE staining,Western blot and quantitative analysis of monolayer transmembrane electrical resistance(TEER)and FITC permeability were then applied to elucidate the mechanism of action of miR-142-5p.Caco-2 cells were lentivirally infected and successful transfection was verified by fluorescence microscopy and RT-qPCR.Dual luciferase and Western blot results showed that CLDN1 was a direct target gene of miR-142-5p(P＜0.001).Compared to the Ts-DNaseⅡ-7 alone treatment group and the OE+Ts-DNase Ⅱ-7 group,the miR-142-5p inhibited expression group and alleviated Ts-DNase Ⅱ-7-induced down-regulation of CLDN1 mRNA and protein levels(P＜0.01 and P＜0.05,respectively)and re-versed the decrease in TEER and elevated permeability(P＜0.01).Ts-DNase Ⅱ-7 up-regulates miR-142-5p expression,causing reduced CLDN1 expression and impaired intestinal barrier function in Caco-2 monolayer cells,which in turn promotes T.spiralis invasion of the intestinal epithelium to achieve further development.
