The connection between tendons and bones is called the tendon bone connection. With the continuous improvement of national sports awareness, excessive exercises and the related intensity are prone to damage the tendon bone connection. Tendon bone healing is a complex repair and healing process involving multiple factors, and good tendon bone healing is a prerequisite for its physiological function. The complexity of tendon bone structure also poses great challenges to the repair of tendon bone injuries. In recent years, researches have found that stem cells, growth factors, macrophages, and other factors are closely related to the healing process of tendon bone injuries, among which macrophages play an important role in the healing process. The authors reviewed relevant research literature in recent years and summarized the role of macrophages in tendon bone healing, in order to provide new ideas and directions for treatment strategies to promote tendon bone healing.

A method for determination and targeted screening of diflorasone components in health products using ultra performance liquid chromatography-quadrupole time of flight mass spectrometry(UPLC-Q-TOF/MS)was established.Four representative diflorasone and esters(diflorasone,diflorasone diacetate,diflorasone-17-propionate,and diflorasone-21-propionate)were selected to optimize the pretreatment conditions,and 10 mL of extraction solvent dosage,15 min of extraction time and 5 g of salting-out agent as the optimal conditions were selected by response surface methodology.The results showed that the four analytes exhibited good linearity within the concentration range of 2.0?100 μg/L with the chromatographic peak area,and the correlation coefficients(R2)were all greater than 0.9990,while the results of recovery and relative standard deviation could satisfy the requirements of determination.The common characteristic ions of diflorasone and esters werem/z121 andm/z335,and their specific structures were obtained by analyzing the cleavage pathway based on the optimized determination conditions.A targeted screening method for other esters of diflorasone based on characteristic ions guidance strategy was established.This method had many advantages such as high efficiency,high sensitivity and good reproducibility,and could be used for targeted screening of diflorasone and esters in health products.The developed characteristic ion guided strategy could be employed to construct mass spectral databases for various glucocorticoids,enabling comprehensive targeted screening across a broad range of compounds.

Objective To explore the relationship between the level of Caveolin-1 and high mobility group protein B1(HMGB-1)in cerebrospinal fluid and the severity of sepsis and their predictive value.Methods A total of 102 children with sepsis were selected in a hospital from June 2021 to December 2023.According to neonatal critical case scoring criteria,the children were divided into mild group(n=41)and severe group(n=61).According to the diagnostic criteria of purulent meningitis and the results of cerebrospinal fluid examina-tion,the children were divided into sepsis complicated with purulent meningitis group(n=16)and simple sepsis group(n=86).The clinical data of the children were collected,and the levels of Caveolin-1,HMGB-1 and inflammatory factors[hypersensitive C-reactive protein(hs-CRP),procalcitonin(PCT)and tumor necro-sis factor-α(TNF-α)]in cerebrospinal fluid of the children were detected by enzyme-linked immunosorbent assay.Multivariate Logistic regression analysis was conducted to analyze the factors affecting the severity of sepsis,and the receiver operating characteristic curve was drawn to analyze the diagnostic value of Caveolin-1 and HMGB-1 in the severity of sepsis and the prediction value of purulent meningitis in the children.Results Compared with mild group,cerebrospinal fluid levels of Caveolin-1 and HMGB-1 in severe group were signifi-cantly increased,and the difference was statistically significant(P<0.05).The levels of PCT,hs-CRP and TNF-α in severe group were significantly higher than those in mild group,and the difference was statistically significant(P<0.05).Multivariate Logistic regression analysis showed that PCT,hs-CRP,TNF-α,Caveolin-1 and HMGB-1 levels were all risk factors for the severity of sepsis in children(P<0.05).The combined diag-nosis of Caveolin-1 and HMGB-1 was significantly better than that of Caveolin-1(Z=2.109,P=0.035),HMGB-1(Z=2.099,P=0.036),PCT(Z=2.487,P=0.013),hs-CRP(Z=2.419,P=0.016)and TNF-α(Z=3.441,P=0.001)were diagnosed alone.Compared with simple sepsis group,cerebrospinal fluid Caveo-lin-1 and HMGB-1 levels in sepsis complicated with purulent meningitis group were significantly increased,and the difference was statistically significant(P<0.05).The combined prediction of Caveolin-1 and HMGB-1 was significantly better than that of Caveolin-1(Z=2.621,P=0.009)and HMGB-1(Z=1.997,P=0.046)alone.Conclusion There are significant increases in the levels of Caveolin-1 and HMGB-1 in chil-dren with severe sepsis or sepsis complicated with purulent meningitis.Caveolin-1 and HMGB-1 have a certain clinical value in evaluating the severity of sepsis in children and predicting whether they are complicated with purulent meningitis.

TCM believes that the main pathogenesis of gastrointestinal dysfunction (GD) after laparoscopic cholecystectomy (LC) is spleen and stomach weakness, liver and stomach disharmony, liver depression and spleen deficiency, and intestinal depression. Moxibustion in the treatment of GD after LC can avoid the aggravation of gastrointestinal burden caused by oral drugs. The intervention methods mainly include suspension moxibustion, umbilical moxibustion, heat sensitive moxibustion, thunder fire moxibustion, warm acupuncture, partition moxibustion, etc. Moxibustion is often performed on the acupoints in liver meridian, spleen meridian, stomach meridian, small intestine meridian, large intestine meridian and Conception Vessel, such as Taichong (LR3), Ganshu (BL18), Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), Wangu (SI4), Hegu (LI4), Zhongwan (CV12), Shenque (CV8) and Qihai (CV6). At present, most studies combined with moxibustion on the basis of conventional Western medicine treatment can significantly improve the efficacy, and have certain advantages in improving gastrointestinal motility decline, intestinal flora imbalance, first exhaust time, gastrointestinal hormone level disorder and intestinal mucosal barrier dysfunction. However, there are still some problems in the existing research: small sample size of clinical research, not perfect scoring scale, not unified treatment plan and operation standard, relatively scarce basic research, relatively simple acupoint research, lack of biochemical evaluation indicators, and the research of national moxibustion needs to be explored and improved in the future.

Objective To understand the equity and influencing factors of maternal health service utilization in Changning District, Shanghai. Methods A convenience sampling method was used to conduct a questionnaire survey among mothers of children aged 1 to 1.5 years old who received health services from the child health care clinics and EPI clinics of 10 community health service centers in Changning District, Shanghai from March to April 2022. Count data was expressed by frequency and percentage. Chi-square analysis, binomial logistic regression analysis, and multivariate logistic regression analysis were used to analyze fairness-related factors. Rate difference, rate ratio and concentration index were used to represent fairness. Results A total of 696 subjects were investigated, with an average age of (33.35±4.76) years. There were statistically significant differences in service utilization among women with different household registrations only in early pregnancy registration (χ²=11.026, P=0.001) and postpartum visits (χ²=4.989, P=0.026). Women with a career showed differently in folic acid supplement (χ²=6.247, P=0.012), early pregnancy registration (χ²=12.989, P=0.002), physical examination in 42 days postpartum (χ²=4.446, P=0.035) and postpartum contraception (χ²=4.061, P=0.044), and the differences were statistically significant. Women with different monthly family income had a statistically significant difference in pre-pregnancy examination (χ²=8.977, P=0.030) and postpartum visit (χ²=16.114, P=0.001). There was a statistically significant difference between women with maternity insurance or not in the early pregnancy registration (χ²=10.576, P=0.001) and physical examination in 42 days postpartum (χ²=8.166, P=0.004). The results of the multivariate analysis showed that occupation (OR=2.616, 95% CI: 1.142-5.990) and maternity insurance (OR=4.490, 95% CI: 1.992~10.120) affected the utilization of service in early pregnancy registration. The monthly household income (OR=0.278, 95% CI: 0.124-0.625) affected the utilization of services in postpartum visit. At the same time, the monthly household income (10,000-19,999: OR=0.286, 95% CI: 0.090-0.907; ≥30,000: OR=0.180, 95% CI: 0.041-0.801) also affected the utilization of service in physical examination in 42 days postpartum. Conclusion The equity of maternal health care service utilization overall is good in central area in Shanghai, but there is still room for improvement. It is necessary to strengthen community mobilization, propagandize maternal health services, and expand the coverage of maternity insurance to improve the equity of maternal health service utilization and provide equal access to maternity health services.

OBJECTIVE: To observe the clinical efficacy of warming acupuncture combined with western medication for oligoasthenoteratozoospermia of kidney-yang insufficiency and its effects on the levels of interleukin (IL)-6 and IL-10 in seminal plasma. METHODS: A total of 60 patients with oligoasthenoteratozoospermia of kidney-yang insufficiency were randomly divided into a combination group and a medication group, with 30 cases in each group. The medication group was treated with levocarnitine oral solution orally, 10 mL once, 3 times a day. On the basis of the treatment in the medication group, warming acupuncture was applied at Baihui (GV20), Guanyuan (CV4) and Mingmen (GV4) in the combination group, once every other day, 3 times a week. Both groups were treated for 12 weeks. Before and after treatment, the TCM syndrome score was observed, the semen routine indexes (the sperm concentration, progressive [PR] sperm motility, PR + non-progressive [NP] sperm motility and sperm malformation rate), the serum sex hormones indexes (follicle-stimulating hormone [FSH], luteinizing hormone [LH], testosterone [T] and estradiol [E₂]), as well as the IL-6 and IL-10 levels in seminal plasma were detected, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, except for the hyposexuality score in the medication group, the each item scores and total scores of TCM syndrome were decreased compared with those before treatment (P<0.01, P<0.05), the sperm malformation rates, serum FSH and LH levels, IL-6 levels in the seminal plasma were decreased compared with those before treatment (P<0.01, P<0.05), the PR sperm motility, PR + NP sperm motility, serum T levels, IL-10 levels in the seminal plasma were increased compared with those before treatment (P<0.01, P<0.05) in the two groups; the sperm concentration was increased compared with that before treatment in the combination group (P<0.01). After treatment, compared with the medication group, except for the hyposexuality and frequent nocturia scores, the each item scores and total score of TCM syndrome were lower (P<0.01, P<0.05); the sperm concentration, PR sperm motility and PR + NP sperm motility, serum T level, IL-10 level in the seminal plasma were higher (P<0.01, P<0.05); sperm malformation rate, serum FSH and LH levels, IL-6 level in the seminal plasma were lower (P<0.01, P<0.05) in the combination group. The total effective rate was 83.8% (25/30) in the combination group, which was superior to 60.0% (18/30) in the medication group (P<0.05). CONCLUSION Warming acupuncture combined with western medication can effectively treat oligoasthenoteratozoospermia of kidney-yang insufficiency, regulate the levels of sex hormones, and its mechanism may be related to the down-regulation of IL-6 level and the up-regulation of IL-10 level in seminal plasma.

Objective:To assess the sound localization ability of patients with unilateral sudden hearing loss during the early period of treatment, to explore its changing characteristics and to analyze influencing factors.Methods:A total of 22 patients with unilateral sudden sensorineural hearing loss, with onset within 3 days, who were hospitalized at Shandong Provincial ENT Hospital between January and April 2024, were collected in this study. The cohort included 13 males and 9 females, with a mean age of 36.5 years. Among them, 10 suffered in the right ear and 12 in the left ear. Additionally, 15 healthy individuals (8 males and 7 females, mean age 29.2 years) were selected as controls. Pure tone audiometry and sound localization tests were reviewed on the first day, third day, fifth day of admission; the third week after onset, and the pure tone average and the root-mean-square error(RMSE) were used as indicators, respectively. The improvement of the ability of sound localization and pure tone average were assessed by correlation analyses using SPSS, version 27.0, and multiple regression analysis was employed to explore effects that might influence sound localization ability.Results:The pure tone threshold and sound localization ability on the third week of onset were improved compared with those on the initial three instances(the first, third, and fifth days of admission). 9 of the 22 patients (40.91%, 9/22) presented normal sound localization ability whereas their hearing loss had not recurred yet. The Spearman correlation analysis revealed a significant positive correlation between the improvement of sound localization ability and hearing improvement ( r=0.57, P<0.001). Meanwhile, multiple regression analysis showed that hearing threshold was a significant factor for sound localization when there was audible frequency. Vice versa, at this circumstance, ages and vertigo were significant factors. Conclusions:For most of the patients with unilateral sudden hearing loss, ability of sound localization improves with the decrease of hearing threshold. Notably, some patients can restore normal levels of sound localization for white noise, even in the presence of hearing loss at certain frequencies, by relying on binaural acoustic cues provided by residual hearing.

Objective To analyze the current status of clinical trial registration of common anorectal diseases in Chinese Clinical Trial Registry(ChiCTR)and the research of TCM.Methods The ChiCTR database was retrieved to collect and organize clinical trials related to hemorrhoids,anal fissures,anal fistulas,perianal abscesses,and perianal eczema.The retrieval time was from the establishment of the database to December 10,2023.Characterization of included registration trials was analyzed.Results A total of 148 registered projects were included,75 of which were TCM-related clinical trials.Among them,134 clinical trials were pre-registered and 121 passed the ethical review.Shanghai,Jiangsu,Guangdong,Beijing and Sichuan accounted for 76.35％of the total number of registrations,and the largest number of registered projects was in Shuguang Hospital affiliated with Shanghai University of Traditional Chinese Medicine.The top 3 funding sources were local finance,self-funding and hospital funding.The registered projects were mainly intervention studies.114 studies used randomized methods and 34 studies were blinded.Conclusion At present,the number of ChiCTR-registered clinical trials on anorectal diseases is on an increasing trend,and the treatment of anorectal diseases with TCM has obvious characteristics.However,there are cases of irregular filling of registration content and uneven regional distribution.

Objective:To investigate the genetic etiology of 15 patients with suspected Marfan syndrome(MFS).Methods:Fifteen patients clinically suspected of having MFS who attended the Women and Children′s Hospital Affiliated to Qingdao University between January 2020 and August 2024 were enrolled. Amniotic fluid samples from fetuses and EDTA-anticoagulated peripheral blood samples from the patients and their family members were collected. Genomic DNA was extracted and subjected to whole exome sequencing(WES). Variants identified in positive cases were further validated by Sanger sequencing. The pathogenicity of the detected variants was assessed according to the guidelines and supplemental criteria of the American College of Medical Genetics and Genomics(ACMG).Results:All 15 patients were found to carry variants in the FBN1 gene, including 9 pathogenic variants, 5 likely pathogenic variants, and 1 variant of uncertain significance(VUS). Notably, eight novel pathogenic or likely pathogenic variants not previously reported in the literature were identified: c. 213G>C, c. 469G>T, c. 3337+ 2dup, c. 4087+ 1G>T, c. 7331_7334dup, c. 8146del, c. 8227dup, and c. 8425_8426insG. According to the revised Ghent criteria(2010), only 2 patients could be clinically diagnosed with MFS prior to WES. However, after incorporating WES-derived molecular evidence, 8 patients fulfilled the diagnostic criteria for MFS.Conclusion:The combination of WES and clinical phenotype assessment can substantially improve the diagnostic yield for MFS. Furthermore, the identification of these novel FBN1 variants expands the mutational spectrum of the gene and provides valuable evidence for future genetic counselling, prenatal diagnosis, and pathogenicity interpretation of neighboring variants.
