Objective To investigate the relationship between different interleukins (ILs) and gynecological tumors, including cervical cancer, endometrial cancer, and uterine leiomyoma using two-sample Mendelian randomization (MR) analysis. Methods IL and gynecological tumor data were obtained from European populations by using the IEU OpenGWAS open database. Two-sample MR analysis was applied, different interleukins were used as exposure factors, significant SNP in GWAS data were selected as instrumental variables, and the instrumental variables were independent of each other. The risk of three kinds of gynecological tumors was analyzed separately to explore the causal relationship between ILs predicted by genes and outcome indicators. The TwoSampleMR package in R language (4.3.1) software was used for statistical analysis. MR analysis was performed using inverse variance weighted, MR Egger regression, weighted median, simple mode, and weighted mode methods. Results IL-18 receptor 1 (P=0.039) and IL-24 (P=0.025) were negatively correlated with the risk of cervical cancer. IL-4 (P=0.040), IL-21 (P=0.026), and IL-37 (P=0.027) were positively correlated with the risk of endometrial cancer. IL-15 receptor subunit alpha (P=0.005) was negatively correlated with the risk of endometrial cancer. IL-17A (P=0.005) and IL-37 (P=0.018) were negatively correlated with the risk of uterine leiomyoma. IL-21 (P=0.035) was positively correlated with the risk of uterine leiomyoma. Conclusion Genetically predicted IL-4, IL-15Rα, IL-17A, IL-18R1, IL-21, IL-24, and IL-37 are causally associated with the risk of three gynecological tumors. Further exploration of the molecular mechanism of ILs in gynecological tumors may provide potential therapeutic targets for the treatment of gynecological tumors.

BACKGROUND:Rheumatoid arthritis is a chronic autoimmune disease characterized by joint pain,swelling,and dysfunction.Acupuncture,as a traditional medical treatment,has proved its effectiveness and safety in many diseases.However,the efficacy of acupuncture in the treatment of rheumatoid arthritis remains controversial.Therefore,the purpose of this study is to evaluate and explore the effect of Tiaodu Tongmai acupuncture in the treatment of preclinical rheumatoid arthritis of different ages through the generalized estimating equation,and to provide a basis for the application of acupuncture in rheumatoid arthritis. OBJECTIVE:To investigate the effect of Tiaodu Tongmai acupuncture therapy on preclinical rheumatoid arthritis(pre-RA)patients at different ages based on generalized estimating equation. METHODS:A total of 123 patients with preclinical rheumatoid arthritis treated from January to September 2023 were selected as the study objects and divided into study group(n=64)and control group(n=59)according to different treatment methods.The study group was given Tiaodu Tongmai acupuncture treatment,and the control group was given acetaminophen tablets.The baseline balance was adjusted by propensity score matching method.The clinical efficacy and cytokine levels before and after treatment between the two groups were compared.The generalized estimating equation model was established to evaluate the efficacy of Tiaodu Tongmai acupuncture therapy on preclinical rheumatoid arthritis patients at different ages. RESULTS AND CONCLUSION:(1)After 0 days of treatment,there were significant differences in joint pain and C-reactive protein expression between study and control groups(P＜0.05).After 4 weeks of treatment,there were significant differences in visual analogue scale scores,joint pain,C-reactive protein and erythrocyte sedimentation rate between the two groups(P＜0.05).After 8 weeks of treatment,there were significant differences in visual analogue scale scores,C-reactive protein and erythrocyte sedimentation rate between the two groups(P＜0.05).After 12 weeks of treatment,there were significant differences in visual analogue scale scores,C-reactive protein and erythrocyte sedimentation rate between the two groups(P＜0.05).(2)The total effective rate of the study group was 93.75%,while that of the control group was 79.17%.The clinical efficacy of the study group was significantly better than that of the control group(P＜0.05).(3)There were significant differences in interleukin-6,interferon-γ,macrophage migration inhibitory factor,rheumatoid factor IgA,rheumatoid factor IgM,metallomatrix proteinase 3,metallomatrix proteinase 9,and anti-cyclic citrulline antibody in the study group before and after treatment(P＜0.05).The levels of interleukin-6,interferon-γ,rheumatoid factor IgA,rheumatoid factor IgM,metallomatrix proteinase 3,metallomatrix proteinase 9,and anti-cyclic citrulline antibody in the control group after treatment were significantly different from those before treatment(P＜0.05).There were significant differences in interleukin-6,interferon-γ,macrophage migration inhibitory factor,rheumatoid factor IgA,rheumatoid factor IgM,metallomatrix proteinase 3,and anti-cyclic citrulline antibody between the two groups after treatment(P＜0.05).(4)After 12 weeks of treatment,the comprehensive efficacy of patients of all ages in the study group was better than that of the control group(P＜0.05).After 8 weeks of treatment,the comprehensive efficacy of patients aged 23-35,36-50,and 51-60 years old in the study group was better than that of the control group(P＜0.05),and the comprehensive efficacy of patients aged 18-22 years old was comparable between the two groups.After 4 weeks of treatment,the comprehensive efficacy of patients aged 36-50 and 51-60 years old in the study group was better than that of the control group(P＜0.05),and the comprehensive efficacy was comparable between the two groups of patients aged 18-22 and 23-35 years.Overall,Tiaodu Tongmai acupuncture therapy has advantages in treating preclinical rheumatoid arthritis patients aged 36-50 and 51-60 years.

bjective　To analyze the drug resistance screening status and drug resistance influencing factors of high-risk groups of drug-resistant pulmonary tuberculosis in Qingdao, and to understand the inclusion of rifampicin patients in treatment, so as to provide a reference for the prevention and treatment of drug-resistant pulmonary tuberculosis. Methods　The medical records of 726 cases of drug-resistant pulmonary tuberculosis among high-risk populations registered in Qingdao from 2018 to 2022 were obtained from the National Health Insurance Information System of the China Center for Disease Control and Prevention. The drug resistance to five anti-tuberculosis drugs, namely isoniazid (INH), rifampicin (RFP), ethambutol (EMB), levofloxacin (Lfx), and amikacin (Am), in the high-risk populations of drug-resistant pulmonary tuberculosis was analyzed. Univariate and multivariate logistic regression were used toidentify factors influencing rifampicin resistance, and the detection and inclusion of treatment for rifampicin-resistant patients were evaluated. Results　Of the 726 subjects, 278 were drug-resistant, with a total drug resistance rate of 38.29%. The drug resistance for the five anti-tuberculosis drugs in descending order was: INH 25.90%(188/726), RFP 22.87%(166/726), Lfx 14.19%(103/726), EMB 11.29%(82/726), Am 2.48%(18/726). Analysis of the drug resistance spectrum showed that among those resistant to one drug, RFP was most common, accounting for 13.67% (38/278); among those resistant to two drugs, INH+RFP was predominant, accounting for 15.83% (44/278); among those resistant to three drugs, INH+RFP+Lfx was most frequent, at 7.19% (22/278); and among those resistant to four drugs, INH+RFP+EMB+Lfx was highest, at 6.12% (17/278). Multivariate logistic regression analysis of rifampicin resistance showed that compared with patients under 25 years of age, the risk of developing rifampicin resistance was lower in the groups aged 45 to under 65 and those aged 65 and above (OR=0.356, 95%CI: 0.181-0.700; OR=0.352, 95%CI: 0.170-0.729). Compared with migrant patients in other provinces, local patients from within the same county or district had a lower risk of developing rifampicin resistance (OR=0.599, 95%CI:0.383-0.962). Compared with patients who were smear-positive at the end of the second month of initial treatment, the risk of developing rifampicin resistance was higher in patients with relapse/return, failure of retreatment/chronic, and other categories of patients (OR=9.380, 95%CI:3.717-23.671;OR=25.749, 95%CI:8.037-82.490; OR=36.651, 95%CI:8.438-159.201). Conclusions　The situation of drug-resistant pulmonary tuberculosis in Qingdao cannot be ignored. Individuals under 25 years old, migrants from other provinces, and patients with relapse/return, failure of retreatment/chronic, and other categories are significant risk factors for developing rifampicin resistance in the high-risk groups of drug-resistant pulmonary tuberculosis.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To explore the clinical value of shear wave elastic imaging(SWE)for renal cortical elasticity in patients with hypertension.Methods According to the diagnostic criteria of 2020 International Society of Hypertension(ISH)Global Hypertension Practice Guidelines,44 patients with simple hypertension admitted to the Department of Cardiology of our hospital were selected and 46 healthy controls were selected for the same period.The general data and and renal function indicators of blood biochemical were recorded.All subjects were examined by two-dimensional ultrasound and SWE elasticity to obtain the conventional ultrasound parameters and the Young's modulus(YM)value of the right.The above parameters between the two groups were compared.The influence factors were analyzed by multiple linear regression among the YM value of the right renal cortex,the general data,conventional ultrasound indicators and renal function indicators in the simple hypertension group.Results The course,systolic blood pressure(SBP)and diastolic blood pressure(DBP)in the simple hypertension group was higher than those in the control group,and the difference was statistically significant(P＜0.05).The YM value of the right renal cortex in the simple hypertension group was higher than that in the control group,and the difference was statistically significant(P＜0.05).The correlation analysis showed that the YM value of the right renal cortex was positively correlated with the duration of hypertension(P＜0.05),but not with age,blood pressure,right renal volume,right renal cortex thickness,right renal artery trunk peak systolic flow velocity(PSV),right renal artery trunk resistance index(RI),blood urea nitrogen,blood creatinine,or uric acid(P＞0.05).Further simple linear regression analysis showed that the duration of hypertension was an independent factor affecting the YM value of the right renal cortex.Conclusion SWE may be used to find the variation in elasticity of renal cortex in patients with simple hypertension.

Objective To investigate the clinical application of 3D printed bolus with specific density in breast cancer radiotherapy,and to evaluate its effects on dose distribution and positioning.Methods Forty post-mastectomy patients undergoing intensity-modulated radiotherapy were randomly enrolled for 3D printed bolus(n=20)and conventional bolus(n=20),and all patients were fixed in the supine position using styrofoam.Conventional positioning was performed based on in-room lasers and body markers,with daily Catalyst HD optical surface monitoring combined with weekly CBCT verification.The absolute dose,patients'skin surface dose,surgical incision,planned field,target area doses(VCTV50Gy,VPTV50Gy)and organs-at-risk doses in patients with different boluses were recorded,and the conformity index and homogeneity index were calculated,and the setup errors using CBCT and Catalyst HD were also analyzed.Results The difference in absolute dose between different boluses was trivial,but the skin surface dose with 3D printed bolus was significantly higher than with conventional bolus[(54.83±0.44)Gyvs(54.43±0.51)Gy,P<0.05].Patients with 3D printed boluses had a higher conformity index than with conventional boluses(0.69±0.04 vs 0.65±0.02).For different boluses,there was no significant difference in VCTV50 Gy,while the VPTV50 Gy and organs-at-risk doses were lower in those with 3D printed bolus than conventional boluses(P<0.05),with heart Vmean of 9.68%±3.24%vs11.43%±3.60%.In patients with 3D printed boluses,both planned field arrangement and surgical incision affected the target doses,and the doses of the target area without an internal breast wrap was greater than those with internal breast wrap(P<0.05).When the field was not wrapped around the internal breast,the surgical incisions only affected VPTV50 Gy,and the VPTV50 Gy was greater with the transverse fusiform incision than with the oblique vertical incision(P<0.05),which were 95.58%±0.51%vs95.44%±0.71%.The optical monitoring accuracies with different boluses differed only in the left-right direction(P<0.05),with(0.08±0.57)cm and(-0.15±0.46)cm for 3D printed and conventional boluses.Conclusion Compared with conventional bolus,3D printed bolus can improve dose distribution and optical monitoring accuracy.The surgical incision and planned field arrangement under 3D-printed bolus would exert effects on target doses.

Objective:To analyze the relationship between early-life famine exposure and the risk of metabolic syndrome in Chinese population.Methods:Relevant literature on the relationship between early-life famine exposure and the risk of metabolic syndrome in the Chinese population was retrieved from databases such as CNKI, Wanfang, VIP, CBM, Web of Science, and PubMed. The search was conducted from the inception of the databases up to October 2022. Two researchers independently extracted and systematically evaluated the data from the literature, and meta-analysis was performed using Stata 16.0 software. Results:A total of 12 publications met the inclusion criteria, including 71 470 study subjects. Meta-analysis results showed that early-life famine exposure increased the risk of metabolic syndrome in the Chinese population( OR=1.28, 95% CI 1.16-1.40). Subgroup analysis showed that both fetal famine exposure( OR=1.25, 95% CI 1.03-1.52) and childhood famine exposure( OR=1.29, 95% CI 1.15-1.45) increased the risk of developing metabolic syndrome compared to the non-exposed group, and this significant association was only found in the female population. Conclusion:Early-life exposure to famine may increase the risk of developing metabolic syndrome in adulthood in the Chinese population, particularly among females.

Objective:To explore the influence of the contours of different parts of the human body on the setup errors of Catalyst HD optical surface imaging (OSI) system-guided radiotherapy.Methods:Using the 3D printing technology, arc- and oval arc-shaped phantoms with base angles of 5°-45° (step length: 5°) were designed to simulate the contours of different body parts of patients. A Catalyst HD system was employed for monitoring, during which the gains and integration time of the system were adjusted. The treatment couches were manually moved (range: -5 mm to 5 mm, with a step length of 2 mm). The ratios of transverse to longitudinal dimensions of all phantoms were recorded. The recorded items also included couch value errors in the anterior-posterior (AP), inferior-superior (SI), and left-right (LR) directions for transversely and longitudinally placed phantoms, as well as the setup errors monitored using the Catalyst HD system. Then, this study presented an analysis of the correlation between phantoms for different body contours and the gains and integration time of the Catalyst HD system. The purpose was to compare the setup errors under the two different placement conditions of phantoms and to analyze the correlation between the monitored values of the Catalyst HD system and couch values.Results:There was a significant linear negative correlation between the gain and the logarithm of integration time required for monitoring using the Catalyst HD system, with a slope of -0.001. There was a certain functional relationship between the intercept and the ratio of the transverse to longitudinal dimensions of the phantoms. Under the same gain, the integration time decreased with an increase in the base angles of phantoms. The Catalyst HD system showed different monitoring accuracy under different placement conditions of the phantoms ( Z = -8.59 to -0.02, P < 0.05), with the monitoring accuracy in the LR and AP directions higher in the transverse position. The correlation between the monitored values of the Catalyst HD system and the actual couch values increased in the LR and SI directions with an increase in the base angle of the phantoms, showing a strong correlation in the case of base angles of ≥ 25°. Furthermore, the correlation was always significant in the AP direction ( R > 0.9). Conclusions:When the best surface images are obtained using the Catalyst HD system, the gains and integration time of the system are correlated with body surface contours. The Catalyst HD system shows high monitoring accuracy in the AP direction. This system shows high accuracy in all directions when the ratios of transverse to longitudinal dimensions are ≤ 2 or the base angles ≥ 25°.

OBJECTIVE: To assess the practical and health economical values of non-invasive prenatal test (NIPT) in Changsha Municipal Public Welfare Program. METHODS: A retrospective analysis was carried out on 149 165 women undergoing NIPT test from April 9, 2018 to December 31, 2019. For pregnant women with high risks, invasive prenatal diagnosis and follow-up of pregnancy outcome were conducted. The cost-benefit of NIPT for Down syndrome was analyzed. RESULTS: NIPT was carried out for 149 165 pregnant women and succeeded in 148 749 cases (99.72%), for which outcome were available in 148 538 (99.86%). 90% of pregnant women from the region accepted the screening with NIPT. 415 (0.27%) were diagnosed as high risk. Among these, 381 (91.81%) accepted amniocentesis, which led to the diagnosis of 212 cases of trisomy 21 (PPV=85.14%), 41 cases with trisomy 18 (PPV=48.81%) and 10 cases with trisomy 13 (PPV=20.83%). The sensitivity and specificity of NIPT for trisomy 21, trisomy 18 and trisomy 13 were (97.70%, 99.98%), (97.62%, 9.97%) and (100%, 99.97%), respectively. In addition, 213 and 30 cases were diagnosed with sex chromosomal aneuploidies (PPV=46.2%) and other autosomal anomalies (PPV=16.57%), respectively. For Down syndrome screening, the cost and benefit of the project was 120.79 million yuan and 1,056.95 million yuan, respectively. The cost-benefit ratio was 1: 8.75, and safety index was 0.0035. CONCLUSION NIPT is a highly accurate screening test for trisomy 21, which was followed by trisomy 18 and sex chromosomal aneuploidies, while it was less accurate for other autosomal aneuploidies. The application of NIPT screening has a high health economical value.

Objective:To investigate the effect of music therapy on depression and anxiety status in maintenance hemodialysis (MHD) patients.Methods:The study was a single-center, open, and randomized controlled trial. The patients with regular hemodialysis of more than 3 months and the Beck depression inventory (BDI) scores ≥10 in China Rehabilitation Research Center from March 1 to April 24, 2021 were selected. Random envelope method was used to divide the enrolled patients into music group and control group. The music therapist selected the treatment music and established the preset repertoire library in the music therapy programs, and the total duration of music was about 2 hours. The music group received listening music therapy of 1.0 to 1.5 hours 3 times a week during routine hemodialysis treatment, while the control group only received routine hemodialysis treatment. All the enrolled patients completed treatment of 8 weeks. The BDI and state-trait anxiety inventory (STAI) were used to assess the psychological status of MHD patients before and after treatment.Results:A total of 64 MHD patients were enrolled, aged (59.19±11.61) years old, among whom 38 patients (59.38%) were males. There were 32 patients in the music group and 32 patients in the control group. BDI scores [2 weeks (9.81±6.25) scores, 8 weeks (8.30±8.49) scores, F=49.75, P<0.001] and STAI scores [2 weeks (49.30±7.27) scores, 8 weeks (47.07±7.39) scores, F=13.09, P<0.001] in the music group decreased significantly after 2 weeks of treatment and remained stable for 8 weeks. After treatment, the BDI scores in the music group were significantly lower than those in the control group [2 weeks (9.81±6.25) scores vs (14.13±7.33) scores, t=-2.53, P=0.014; 8 weeks (8.30±8.49) scores vs (12.56±5.67) scores, t=-2.34, P=0.023], and STAI scores in the music group were significantly lower than those in the control group [2 weeks (49.30±7.27) scores vs (54.00±8.36) scores, t=-2.06, P=0.043; 8 weeks (47.07±7.39) scores vs (51.34±8.87) scores, t=-2.06, P=0.044]. Conclusion:Music therapy can improve depression and anxiety of MHD patients quickly and effectively.
