Objective To develop and evaluate dietary and exercise intervention program for over-weight/obese patients with polycystic ovary syndrome(PCOS).Methods Seventy patients with over-weight/obese PCOS were prospectively selected as research subjects and divided into intervention group(n=35)and control group(n=35)according to random number table method.According to the completion of the intervention plan,29 cases were finally included in the intervention group and 28 cases in the control group.The control group was given conventional nursing intervention,while the intervention group was applied with the diet and exercise intervention program for overweight/obese patients with PCOS.Both groups were intervened for 3 months.The physical indicators,PCOS sign scores,natural pregnancy rate,degree of self-body image distress(Multidimensional Self-body Im-age Relationship Questionnaire-Appearance Subscale)and self-efficacy level(Self-efficacy Scale)before and after the intervention were compared between the two groups.The occurrence of adverse reactions during the intervention period between the two groups were compared.Results After 1 month and 3 months of intervention,the body mass index(BMI)and PC OS sign score of the pa-tients in the intervention group were significantly lower than those in the control group(P＜0.05).The natural conception rate of the intervention group was 34.48％(10/29),which was significantly higher than 10.71％(3/28)of the control group(P＜0.05).After 1 month and 3 months of inter-vention,the scores of the self-body image relationship-appearance subscale of the patients in the inter-vention group were significantly higher than those in the control group(P＜0.001).After 3 months of intervention,the score of the Self-efficacy Scale of patients in the intervention group was significantly higher than that in the control group(P＜0.001).During the intervention period,no adverse reac-tions caused by diet and exercise intervention occurred in either group.Conclusion Implementing a diet and exercise intervention program for overweight/obese patients with PCOS is beneficial for re-ducing patients' BMI,increasing the natural pregnancy rate,improving self-body image disorders,and enhancing self-efficacy.

ObjectiveTo study the relationship between qi stagnation constitution and suboptimal health status (SHS) or lifestyle.MethodsFrom 2012 to 2013, we conducted a cross-sectional survey of 24 159 Chinese individuals aged 12–80 years. The qi stagnation constitution was assessed using the Constitution in Chinese Medicine Questionnaire. Health status was evaluated through medical records and the Subhealth Measurement Scale V1.0 (SHMS V1.0). Health-promoting lifestyles were measured using the Health-Promoting Lifestyle Profile II (HPLP-II).ResultsOf the 24 159 participants, 16.1% and 15.2% were classified as “always” and “sometimes” having the qi stagnation constitution, respectively. Those classified as “rarely” having the qi stagnation constitution scored higher on both the HPLP-II and SHMS V1.0. The participants classified as “always” having the qi stagnation constitution showed a significant association with SHS or disease compared to other imbalanced constitutions. Those in the “always” category were approximately 21 times more likely to be classified as having SHS (odds ratio [OR]: 21.17, 95% confidence interval [CI]: 15.74–28.45), whereas those in the “sometimes” category were approximately six times more likely (OR: 5.89, 95% CI: 5.04–6.90). Accordingly, the qi stagnation constitution score was significantly associated with the diagnosis of SHS, with an area under the curve of 0.77 (P .001). A score of 18.75 yielded the highest Youden Index (0.407), with a sensitivity of 60.5% and a specificity of 80.3%. Significant associations were observed between health-promoting lifestyles and qi stagnation constitution severity in an ordinal regression analysis (P .001). Protective factors included stress management (OR: 1.59), self-actualization (OR: 1.57), and exercise (OR: 1.36). In contrast, poorer interpersonal relationships (OR: 0.79), greater health responsibilities (OR: 0.86), and poorer nutrition (OR: 0.91) were associated with increased severity.ConclusionModulating the qi stagnation constitution through lifestyle interventions may help prevent the progression of SHS to disease, which aligns with core preventive principles in traditional Chinese medicine.

Interventional oncology plays an important role in the treatment of liver cancer.With the emerging of the concept of precision and individualized treatment of tumors in clinical practice,the use of angiographic system becomes very frequent.The angiographic system plays an important role in optimizing the treatment regimen,in improving the therapeutic outcome,and in accurately predicting the tumor response.The use of angiography system with its post-processing software can achieve the visualization of tumor and its feeding arteries,reduce non-target deposition,predict curative efficacy,efficiently guide ablation procedures,plan treatment safety boundaries,identify therapeutic drug delivery dose when combined with the emerging visualization of microspheres,and achieve individualized dosimetry.This review introduces the application of angiographic system and its post-processing software in interventional oncology of liver cancer,and discusses the potential and shortcomings of angiographic system.

Objective:To investigate the status of allostatic load (AL) in patients with polycystic ovary syndrome (PCOS) and its influence on the clinical outcomes of in vitro fertilization-embryo transfer.Methods:This was a prospective study. By using convenient sampling method, 421 patients with PCOS (PCOS group) and 372 control infertility patients (control group) in the Reproductive Center of the First Affiliated Hospital of Anhui Medical University from April 2022 to January 2024 were investigated for basic information, physical examination, laboratory examination and follow-up of clinical outcomes. The total score of AL was calculated using 16 related indicators of cardiovascular system, metabolic system and immune system, and AL>3 was used as the judgment criteria for the high level AL group and the low level AL group. The differences in general data, embryo development and clinical outcomes between the groups were compared.Results:There were 222 cases (52.7%, 222/421) in PCOS low level AL group and 199 cases (47.3%, 199/421) in PCOS high level AL group. There were 214 patients (57.5%, 214/372) in the control low level AL group and 158 patients (42.5%, 158/372) in the control high level AL group. Embryo development outcomes: number of oocytes retrieved (median: 12, 12, 19, 14, respectively; P<0.001), number of two pronuclei (median: 8, 7, 11, 8, respectively; P<0.001), number of fertilization (median: 9, 9, 13, 10, respectively; P<0.001), number of metaphase of meiosis Ⅱ oocytes (median: 9, 8, 13, 10, respectively; P<0.001), number of transferable embryos (median: 5, 5, 7, 6, respectively; P<0.001), number of high-quality embryos (median: 4, 3, 6, 5, respectively; P<0.001), gonadotropin(Gn) starting dosage (median: 150, 200, 150, 200 U, respectively; P<0.001), total dosage of Gn (median: 1 800, 2 075, 1 575, 2 025 U, respectively; P<0.001), duration of Gn used (median: 10, 10, 10, 10 days, respectively; P=0.027) in the control low level AL group, control high level AL group, PCOS low level AL group and PCOS high level AL group were significantly different. Pairings between groups showed that number of oocytes retrieved, number of two pronuclei, number of fertilization, number of metaphase of meiosis Ⅱ oocytes and number of transferable embryos in PCOS high level AL group were lower than those in PCOS low level AL group (all P<0.05); Gn starting dosage and total dosage of Gn in PCOS low level AL group were lower than those in the other three groups (all P<0.05); duration of Gn used in PCOS high level AL group was higher than that PCOS low level AL group ( P<0.05). Clinical outcomes: the control low level AL group, control high level AL group, PCOS low level AL group and PCOS high level AL group underwent fresh transplantation [27.4% (57/208), 24.4% (38/156), 15.1% (32/212), 17.1% (33/193), respectively; P=0.006] and the proportion of transplanted day 5 embryos [82.7% (172/208), 77.6% (121/156), 91.0% (193/212), 86.5% (167/193), respectively; P=0.018] were statistically significant. There were no significant differences in fertilization rate, biochemical pregnancy rate, clinical pregnancy rate, multiple pregnancy rate and early abortion rate among the four groups (all P>0.05). Conclusion:The high level of AL in PCOS patients may affect the outcomes of embryo development, and more attention should be paid to AL in PCOS patients to reduce stress.

Objective:To analyze the epidemiological characteristics of wasting, spinal curvature abnormalities and multimorbidity among children and adolescents aged 6-18 in Inner Mongolia and explore the related factors of these two health problems.Methods:In September 2022, a stratified random cluster sampling method was employed to select 188 635 children and adolescents aged 6-18 in Inner Mongolia for physical examinations and questionnaire surveys. Data on height, weight, as well as dietary behavior, physical activity, classroom environment, academic tasks, writing posture, and screen behavior were collected. The epidemiological characteristics of wasting, spinal curvature abnormalities and multimorbidity were analyzed. Additionally, a multivariate logistic regression model was used to analyze the factors associated with wasting, spinal curvature abnormalities and multimorbidity.Results:A total of 188 635 children and adolescents aged 6-18 years participated in this study, including 95 393 boys (50.6%) with an average age of (11.53±3.32) years. The detection rate of wasting was 3.79%, with a higher detection rate in boys (4.18%) than in girls (3.38%) ( P<0.001). The detection rate of spinal curvature abnormalities was 3.64%, with a higher detection rate in girls (4.04%) than in boys (3.25%) ( P<0.001). The detection rate of multimorbidity between wasting and spinal curvature abnormalities was 0.17%, and there was no statistically significant difference between genders ( P>0.05). The detection rates of wasting, spinal curvature abnormalities, and multimorbidity all increased with age ( P t<0.001). The multivariate logistic regression analysis showed that, after adjusting for gender, age, urban/rural status, and school grade, compared to children and adolescents who exercised ≥1 hour of moderate-to-vigorous physical activity (MVPA) for at least 5 days per week and had daily screen time <2 hours, those who exercised <5 days per week ( OR=1.28, 95% CI: 1.19-1.37) and had daily screen time ≥2 hours ( OR=1.11, 95% CI: 1.03-1.19) had a higher risk of wasting. Compared to children and adolescents who had ≥5 physical education (PE) classes per week, adjusted desk and chair height,<1 hour of after-school study/writing time, and whose parents or teachers rarely or never reminded them about posture, those with <5 PE classes per week ( OR=1.11, 95% CI: 1.02-1.21), unadjusted desk and chair height ( OR=1.08, 95% CI: 1.01-1.15),≥1 hour of after-school study/writing time ( OR=1.15, 95% CI: 1.07-1.24), frequent reminders from parents ( OR=1.16, 95% CI: 1.09-1.23), and frequent reminders from teachers ( OR=1.10, 95% CI: 1.04-1.16) had a higher risk of spinal curvature abnormalities. Compared to children and adolescents who did not consume sugary drinks daily, exercised ≥1 hour of MVPA for at least 5 days per week, and whose teachers rarely or never reminded them about posture, those who consumed sugary drinks daily ( OR=1.61, 95% CI: 1.00-2.46), exercised <5 days per week ( OR=1.33, 95% CI: 1.01-1.79), and had teachers who frequently reminded them about posture ( OR=1.35, 95% CI: 1.05-1.75) had a higher risk of multimorbidity between wasting and spinal curvature abnormalities. Conclusion:The detection rates of wasting, spinal curvature abnormalities and multimorbidity among children and adolescents aged 6-18 in Inner Mongolia are generally low, with an increasing trend observed with age. Both lifestyle and school environmental factors are associated with wasting, spinal curvature abnormalities and multimorbidity.

Polycystic ovary syndrome (PCOS) is a common chronic disease in women of childbearing age, which mainly threatens women's reproductive health and metabolism. Globally, 5%-20% of women of childbearing age are affected, depending on the diagnostic criteria. There is currently no effective treatment, so early and long-term management is crucial. International evidence-based guidelines for the assessment and management of PCOS recommend lifestyle interventions, such as exercise alone or a variety of diets combined with exercise and behavioral strategies, as first-line management options for women with PCOS to improve metabolic health. This review summarizes the new progress in the application of lifestyle interventions in PCOS patients from different dietary patterns, exercise interventions and action management in order to improve the attention of medical staff in China to the female population of PCOS and provide technical reference for the future application in the health management practice of PCOS patients.

Objective:To explore the effectiveness of a compliance-based sequential exercise model in the rehabilitation of patients after anterior cruciate ligament (ACL) reconstruction.Methods:A convenience sampling method was used to select 104 patients who underwent arthroscopic ACL reconstruction at The First Affiliated Hospital of Zhengzhou University from April 2022 to July 2023. Patients were randomly divided into an observation group and a control group (52 patients in each group). The control group received in-hospital and home-based sequential rehabilitation exercises, while the observation group followed a compliance-based graded sequential rehabilitation exercise program. Both groups received the intervention for 3 months. The differences in knee function scores and rehabilitation self-efficacy scale scores between the two groups before and after the intervention were compared.Results:After the intervention, both groups showed significant increases in knee function scores and rehabilitation self-efficacy scale scores compared to pre-intervention scores ( P<0.01). The observation group had higher knee function scores and rehabilitation self-efficacy scale scores than the control group, with significant differences ( P<0.01). Additionally, the knee function grading in the observation group was better than in the control group after the intervention, with significant differences ( P<0.01) . Conclusions:Compliance-based sequential rehabilitation exercises effectively promote knee function recovery in patients after ACL reconstruction and improve patients' rehabilitation self-efficacy.
