OBJECTIVE: To evaluate precise assessment methods for predicting the optimal acetabular cup size in total hip arthroplasty (THA). METHODS: A clinical data of 73 patients (80 hips) who underwent primary THA between December 2022 and July 2024 and met the inclusion criteria was analyzed. There were 39 males and 34 females with an average age of 66.3 years (range, 56-78 years). Among them, 66 cases were unilateral THA and 7 were bilateral THAs. There were 29 patients (34 hips) of osteoarthritis, 35 patients (35 hips) of femoral neck fractures, and 9 patients (11 hips) of osteonecrosis of the femoral head. Based on anteroposterior pelvic X-ray films, three methods were employed to predict acetabular cup size, including preoperative template planning, radiographic femoral head diameter (FHD) measurement, and intraoperative FHD measurement. The predicted acetabular cup sizes from these methods were compared with the actual implanted sizes. RESULTS: The predicted acetabular cup sizes using the preoperative template planning, radiographic FHD measurement, and intraoperative FHD measurement were (51.25±2.81), (49.72±3.11), and (49.90±2.74) mm, respectively, compared to the actual implanted cup size of (50.57±2.74) mm, with no significant difference ( P>0.05). Regarding agreement with the actual implanted cup size, the preoperative template planning achieved exact matches in 35 hips (43.75%), one-size deviation in 41 hips (51.25%), and two-size deviations in 4 hips (5%); the radiographic FHD measurement achieved exact matches in 12 hips (15%), one-size deviation in 57 hips (71.25%), and two-size deviations in 11 hips (13.75%); and the intraoperative FHD measurement achieved exact matches in 26 hips (32.5%), one-size deviation in 52 hips (65%), and two-size deviations in 2 hips (2.5%). There were significant differences in agreement distributions between the three methods and the actual implanted cup sizes ( H=18.579, P<0.001). CONCLUSION The intraoperative FHD measurement, as a simple, cost-effective, and accurate method, effectively guides acetabular cup selection, reduces the risk of prosthesis wear, enhances postoperative joint stability.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

[Objective]To assess the repeatability(intra-operator variability)and reproducibility(inter-operator variability)of a new partial coherence interferometry(PCI)-based ocular biometer,Myopia Master,and its agreement with IOL Master 500 for measuring axial length(AL)and corneal curvature(K)in children aged 8-12 years.[Methods]The same operator measured school children with the Myopia Master and the IOL Master 500 in random order to assess agreement.Additionally,some of these children received measurements from another operator using the Myopia Master to assess repeatability and reproducibility.AL,flat keratometry(Kf),steep keratometry(Ks),mean keratometry(Km),J0 and J45 were analyzed.The repeatability and reproducibility were assessed by the within-subject standard deviation(Sw),test-retest repeatability(TRT),coefficient of variation(CoV)and intra-class correlation coefficient(ICC).The agree-ment between the Myopia Master and the IOL Master 500 was assessed by Bland-Altman plots and 95%limits of agree-ment(LoA).[Results]Both repeatability and reproducibility of the Myopia Master were high for AL measurements(Sw=0.02 mm,ICC=0.999;Sw=0.04 mm,ICC=0.998),but moderate for K measurements(Sw range,0.04 to 0.12 D,ICC range,0.861 to 0.991;Sw range,0.06 to 0.20 D,ICC range,0.835 to 0.992).There were significant mean differences be-tween the Myopia Master and the IOL Master 500 in measurements of AL(-0.01±0.04)mm,Kf(-0.09±0.15)D,Ks(-0.47±0.40)D,and Km(-0.28±0.23)D,J0(0.18±0.20)D and J45(-0.01±0.12)D.[Conclusions]The Myopia Master provided high repeatability and reproducibility for AL measurements in schoolchildren with myopia,but the Myopia Master and the IOL Master 500 cannot be used interchangeably in measuring AL and K.

Objective:To explore the impact of different six-character qigong training modes on respiratory muscle function early after a stroke.Methods:Sixty-six stroke survivors in the early stage of recovery were randomly divided into a control group, a modified training group, and an ancient training group, each of 22. In addition to routine rehabilitation training, the control group received conventional respiratory training. The modified training and ancient training groups were trained in modified six-character qigong or ancient six-character qigong, respectively, for two weeks. Before the treatment, after the two weeks and one month later, maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), forced expiratory volume in one second, forced vital capacity, peak expiratory flow, maximum mid-expiratory flow, and peak inspiratory flow were measured. Diaphragm mobility during quiet inspiration and maximum inspiration were also quantified.Results:After 2 weeks of treatment and at 1 and 3 months after the end of the treatment, all three groups showed significant improvement in MIP, MEP and the pulmonary ventilation indicators, but the average improvement in the modified training group was significantly greater than in the other two groups. Their average diaphragm mobility was also significantly greater.Conclusion:Modified six-character qigong respiratory training is more effective than its ancient counterpart in improving respiratory muscle function, pulmonary ventilation, and diaphragm mobility early after a stroke, with effects which persist for at least one month.

Objective:To assess the correlation between circulating chemerin and two indicators of renal function, estimated glomerular filtration rate (eGFR) and urine albumin creatinine ratio (UACR), in individuals with type 2 diabetes and to determine whether chemerin is an independent marker of early renal insufficiency.Methods:A total of 742 patients with type 2 diabetes were recruited into the cross-sectional community study. Basic information, anthropometric parameters, and biochemical parameters of these individuals were determined and collected, and serum chemerin level was measured using enzyme-linked immunosorbent assay.Results:Chemerin levels were significantly higher in the eGFR-impaired group compared with eGFR-normal group, and macroalbuminuria group compared to the normal or microalbuminuria groups. Spearman′ rank correlation analysis showed serum chemerin level was correlated with eGFR ( r=-0.25, P<0.001), UACR ( r=0.23, P<0.001) and some other biochemical indicators such as triglyceride. And univariate and multivariate logistic regression analyses revealed circulating chemerin was an independent risk factor for eGFR impairment or proteinuria after adjusting corresponding covariates. Receiver operating characteristic (ROC) curve analysis showed that the area under curve (AUC) of circulating chemerin for predicting early impaired eGFR in type 2 diabetes was 0.747, while the AUC of circulating chemerin for predicting macroalbuminuria in type 2 diabetes was 0.748. Conclusion:Circulating chemerin is associated with eGFR or UACR and may be a potential diagnostic marker for early renal insufficiency in type 2 diabetes.

Background::Urticaria is a common skin disease characterized by episodes of wheals, and it has a negative effect on patients’ quality of life. Large-scale population-based epidemiological studies of urticaria are scarce in China. The aim of this survey was to determine the prevalence, clinical forms, and risk factors of urticaria in the Chinese population.Methods::This survey was conducted in 35 cities from 31 provinces, autonomous regions, and municipalities of China. Two to three communities in each city were selected in this investigation. Participants completed questionnaires and received dermatological examinations. We analyzed the prevalence, clinical forms, and risk factors of urticaria.Results::In total, 44,875 questionnaires were distributed and 41,041 valid questionnaires were collected (17,563 male and 23,478 female participants). The lifetime prevalence of urticaria was 7.30%, with 8.26% in female and 6.34% in male individuals ( P < 0.05). The point prevalence of urticaria was 0.75%, with 0.79% in female and 0.71% in male individuals ( P < 0.05). Concomitant angioedema was found in 6.16% of patients. Adults had a higher prevalence of urticaria than adolescents and children. Living in urban areas, exposure to pollutants, an anxious or depressed psychological status, a personal and family history of allergy, thyroid diseases, and Helicobacter pylori infection were associated with a higher prevalence of urticaria. Smoking was correlated with a reduced risk of urticaria. Conclusion::This study demonstrated that the lifetime prevalence of urticaria was 7.30% and the point prevalence was 0.75% in the Chinese population; women had a higher prevalence of urticaria than men. Various factors were correlated with urticaria.

Long non-coding RNAs (lncRNAs) are a family of non-protein-coding RNAs that span a length of over 200 nucleotides. Research reports have illustrated that lncRNAs are involved in various cellular processes and that their abnormal expression leads to the occurrence and development of various tumors. Colon cancer-associated transcript 2 (CCAT2) was first reported as an oncogene in colon cancer. LncRNA CCAT2 is abnormally expressed in hepatocellular carcinoma, cholangiocarcinoma, lung cancer, breast cancer, ovarian cancer, glioma, and other tumors. In tumor tissues, abnormally overexpressed CCAT2 can affect cell proliferation, migration, epithelial-mesenchymal transition, apoptosis, and other biological behaviors through endogenous RNAs mechanisms, various signaling pathways, transcriptional regulation, and other complex mechanisms. Additionally, the overexpression of CCAT2 is also closely related to the tumor size, tumor node metastasis (TNM) stage, survival time, and other prognostic factors, suggesting that it is a potential prognostic indicator. This article reviews the biological functions of CCAT2 and its mechanisms of action in tumors from previous studies. In this review, we attempt to provide a molecular basis for future clinical applications of lncRNA CCAT2.

Objective To analyze and compare the outcomes of esophageal carcinoma treated with simultaneous integrated boost intensity-modulated radiation therapy (SIB-IMRT) and late course boost intensity-modulated radiation therapy (LCB-IMRT).Methods We retrospectively analyzed 128 patients with esophageal squamous cell carcinoma who were treated with SIB-IMRT or LCB-IMRT at the fifth department of radiation oncology in our hospital,from January 2009 to August 2015.Propensity score matching analysis was used to balance the variables differences in the two groups.Survival,failure patterns and toxicities were observed and compared between the two groups.Results one hundred and eleven patients were finally included after propensity scores matching.The 1-,3-and 5-year local control rates and survival rates were 83.6％ vs.81.7％,70.8％ vs.46.3％ and 66.0％ vs.38.2％ in the whole group,respectively.The 1-,3-and 5-year local control rates of SIB-IMRT and LCB-IMRT group were 81.6％ vs.88.0％,72.3％ vs.67.6％ and68.5％ vs.60.8％,respectively (P＞0.05).The 1-,3-and 5-year survival rates of SIB-IMRT and LCB-IMRT group were 81.3％ vs.82.4％,51.7％ vs.36.7％ and 45.8％ vs.26.7％,respectively (P ＞ 0.05).There was no statistical difference between the two group in ≥ grade 3 toxicities (P ＞ 0.05).There were 40 (36.0％) patients result in treatment failure in all.The treatment failure rates in SIB-IMRT and LCB-IMRT group were 33.8％ (26/77) vs.41.2％ (14/34),respectively (P ＞ 0.05).The local failure accounted for 65.0％ (26/40) of all treatment-related failures.Conclusions The toxicities of esophageal squamous cell carcinoma treated with SIB-IMRT and LCB-IMRT have no significant differences and were well tolerated.There were no significant differences in local control rates and survival rates between the two groups.However,SIB-IMRT had better trend than LCB-IMRT.Given SIB-IMRT's convenient manipulation,it could be a better choice in the treatment of advanced esophageal carcinoma.

Objective To observe the short- and long-term efficacies of acupuncture in treating metabolic syndrome (MS). Method A hundred MS patients were randomized into an acupuncture group and a Western medication group. In addition to basic treatment, acupuncture was used in the acupuncture group, while Western medication was adopted in the Western medication group. The fasting plasma glucose (FPG), high-density lipoprotein (HDL), insulin (INS), triglyceride (TG), blood pressure (BP), weight circumference (WC), body mass index (BMI), and MS score were evaluated before and after treatment, and a month and 3 months after the treatment. Result There was no significant difference in comparing the short-term therapeutic efficacy between the two groups after treatment, while the long-term therapeutic efficacy of the acupuncture group was superior to that of the Western medication group (P<0.01); the FPG, INS, TG, HDL, BP, and MS score were significantly improved after treatment and a month after the treatment in both groups (P<0.01); the acupuncture group had significant improvements in WC and BMI after treatment and a month after the treatment (P<0.01), significantly superior to the Western medication group (P<0.01); the acupuncture group showed marked improvement in INS, HDL, WC, and BMI 3 months after the treatment (P<0.01), significantly superior to the Western medication group (P<0.01,P<0.05). Conclusion Acupuncture can produce a similar short-term but a better long-term therapeutic efficacy compared to Western medication. Hence, acupuncture can be taken as an assistant intervention for MS.
