Objective:This study aimed to explore the status of radiological Kashin-Beck disease (KBD) among school-aged children in Chamdo City, Tibet, through a 3-year monitoring survey, providing epidemiological evidence for prevention and control strategies.Methods:The target areas for this study were Luolong, Bianba, and Basu counties in Chamdo City, Tibet Autonomous Region, identified as having the most severe historical cases of KBD. Children aged 7-12 years attending school were enrolled as study subjects. Anteroposterior X-ray films of the right-hand were taken, and radiological diagnoses were made based on the "Diagnosis of Kashin-Beck Disease" criteria (WS/T 207-2010). Two experienced researchers independently reviewed the X-rays, and intra- and inter-group consistency were assessed using weighted Kappa values and percentage agreement. Cross-sectional surveys were conducted in 2017 and 2020 to describe the X-ray detection rates of KBD, and logistic regression analysis was employed to construct a predictive model of risk factors for radiological KBD cases.Results:In 2017, a total of 5,711 children aged 7-12 years in Chamdo City, Tibet, participated in the baseline cross-sectional survey (average age 9.2 years, 48.0% female), with 28 cases of radiological KBD. The age- and gender-standardized prevalence rate was 0.527%. In 2020, 6,771 participants (average age 9.3 years, 49.5% female) underwent a second cross-sectional survey, with 9 cases of radiological KBD and a standardized prevalence rate of 0.134%. Logistic regression analysis indicated that older age [ OR=2.439, 95% CI(1.299, 4.580), P=0.006] and female gender [ OR=8.157, 95% CI(1.016, 65.528), P=0.048] were independent risk factors for radiological KBD cases. Conversely, higher residential altitude, under the premise of Tibet's high altitude, was a protective factor [ OR=0.995, 95% CI(0.990, 0.999), P=0.032). Conclusion:The radiographically positive detection rate of KBD among school-aged children in Chamdo City, Tibet Autonomous Region, is at an extremely low level and showing a declining trend, reaching the historical standard in 2020. Considering the absence of positive signs in affected children, it suggests that local KBD has been effectively eliminated.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To explore the effects of the subspecialty group management mode in Operating Room nursing for patients with laryngeal cancer.Methods:Totally 70 patients with laryngeal cancer admitted to Henan Provincial People's Hospital from January to December 2020 who underwent laryngectomy concurrently with routine surgical nursing were selected as the control group, and 70 laryngeal cancer patients admitted from January to December 2021 who underwent laryngectomy and the subspecialty group management concurrently as the research group by convenience sampling. 84 nurses from the Operating Room of the hospital, including 14 specialist team leaders, were selected for the study. The preoperative waiting time, operation time, operation compliance rate, and nursing satisfaction were compared between the two groups. The nursing competence scores of Operating Room nurses were evaluated and compared before and after the introduction of the subspecialty group nursing management mode.Results:Patients in the research group reported a shorter preoperative waiting time and operation time, higher compliance rates in preoperative device preparation, drug preparation, body position placement, venipuncture, catheter indwelling, device cleaning, and higher nursing satisfaction than patients in the control group, with statistically significant differences ( P<0.05) . One year after the implementation of the subspecialty group nursing management mode, the nursing core competence scores of the specialist team leader and the post competency scores of all nurses in the Operating Room were higher than those before the implementation, and the differences were statistically significant ( P<0.05) . Conclusions:The subspecialty group management mode can significantly improve the nursing competence of Operating Room nurses, shorten the preoperative waiting time and operation time, and improve the compliance rate of surgical work and nursing satisfaction.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

Objective:To investigate the diagnostic value of circular RNA circ_100367 in thyroid cancer (THCA) and its relationship with immune-related factors.Methods:According to the data chip provided by the National Center for Biotechnology Information (NCBI) website, the differentially expressed circRNAs in THCA were analyzed, then circ_100367 was included in this study. The serum of 175 THCA patients and healthy people were collected, and the expression levels of circ_100367 and its linear transcript DCAF8 mRNA in serum samples were detected by qRT-PCR, and the correlation between circ_100367 and DCAF8 was calculated. The correlation between the expression of circ_100367 and the clinicopathological characteristicsof the patients, immune infiltration level and immunosuppressive factor PD-1 was analyzed.Results:Compared with serum of healthy people (1.00±0.37) , expression level of circ_100367 in serum of THCA patients was significantly increased (1.37±0.41) ( t=8.80, P<0.001) , and there was no significant difference in DCAF8 mRNA expression ( t=1.67, P=0.095) , but circ_100367 was positively correlated with DCAF8 mRNA expression ( r=0.17, P=0.028) . Analysis of expression and clinicopathological characteristics of circ_100367 showed that compared with patients in M0 group (1.26±0.40) , circ_100367 was overexpressed in M1 and Mx patients (1.43±0.40) ( t=2.63, P=0.009) ; compared with N0 patients (1.24±0.36) , circ_100367 was overexpressed in serum of N1 and Nx patients (1.45±0.42) ( t=3.48, P=0.001) ; compared with serum of patients with negative lymph node detection (1.28±0.36) , circ_100367 was overexpressed in serum of positive patients (1.42±0.43) ( t=2.14, P=0.034) ; compared with T1+T2 stage patients (1.30±0.37) , circ_100367 expression was overexpressed in serum ofT3+T4 patients (1.40±0.43) ( t=2.22, P=0.028) . Analysis of the expression and immune infiltration levels of circ_100367 found that highly expressed circ_100367 was associated with CD8+ T cells ( r=0.25, P=0.024) , macrophages ( r=0.22, P=0.038) , CD4+ T cells ( r=0.25, P=0.020) and B cell ( r=0.23, P=0.033) levels. The expression of circ_100367 was also positively correlated with the immunosuppressive factor PD-1 ( r=0.19, P=0.011) . Conclusion:circ_100367 can be used as a marker for the diagnosis of THCA and its expression is strongly correlated with immune-related factors.

Drug optimization, which improves drug potency/specificity by structure‒activity relationship (SAR) and drug-like properties, is rigorously performed to select drug candidates for clinical trials. However, the current drug optimization may overlook the structure‒tissue exposure/selectivity-relationship (STR) in disease-targeted tissues vs. normal tissues, which may mislead the drug candidate selection and impact the balance of clinical efficacy/toxicity. In this study, we investigated the STR in correlation with observed clinical efficacy/toxicity using seven selective estrogen receptor modulators (SERMs) that have similar structures, same molecular target, and similar/different pharmacokinetics. The results showed that drug's plasma exposure was not correlated with drug's exposures in the target tissues (tumor, fat pad, bone, uterus), while tissue exposure/selectivity of SERMs was correlated with clinical efficacy/safety. Slight structure modifications of four SERMs did not change drug's plasma exposure but altered drug's tissue exposure/selectivity. Seven SERMs with high protein binding showed higher accumulation in tumors compared to surrounding normal tissues, which is likely due to tumor EPR effect of protein-bound drugs. These suggest that STR alters drug's tissue exposure/selectivity in disease-targeted tissues vs. normal tissues impacting clinical efficacy/toxicity. Drug optimization needs to balance the SAR and STR in selecting drug candidate for clinical trial to improve success of clinical drug development.
