BACKGROUND:Acupotomy is an effective method for the clinical treatment of osteoarthritis,with affirmed clinical outcomes,but the specific mechanisms remain unclear OBJECTIVE:To investigate the role of acupotomy in modulating chondrocyte autophagy to promote chondrocyte homeostasis in osteoarthritis. METHODS:Twenty-eight New Zealand rabbits were randomly divided into control group,osteoarthritis group,acupotomy group,and hyaluronic acid group,with seven rabbits in each group.The knee osteoarthritis rabbit model was prepared using the Videman method in the latter three groups.After modeling,the control group and osteoarthritis group received no interventions.The acupotomy group received acupotomy treatment 15 minutes per time,once a week,while the hyaluronic acid group received intra-articular injection of hyaluronic acid once a week,with a continuous treatment duration of 5 weeks.The day after the final intervention,knee joint macrostructure was observed using DR imaging,chondrocyte ultrastructure was examined through transmission electron microscopy,apoptosis of chondrocytes was assessed using Tunel staining,and western blot analysis was used to detect the expression of proteins related to the PI3K/Akt/mTOR pathway. RESULTS AND CONCLUSION:The DR imaging results revealed that the osteoarthritis group exhibited narrowed knee joint spaces and the formation of periarticular osteophytes,while the hyaluronic acid group and acupotomy group showed widened knee joint spaces with a reduction in periarticular osteophytes.Transmission electron microscopy results demonstrated a decreased number of autophagosomes in chondrocytes in the osteoarthritis group,along with nuclear shrinkage,nuclear membrane rupture,incomplete organelle morphology,and a clear tendency towards cell death.In contrast,both the hyaluronic acid group and acupotomy group exhibited a significant increase in autophagosomes,intact nuclear membranes,and a well-preserved cellular state.Tunel staining results indicated a considerable decrease in the number of apoptotic cells in the hyaluronic acid group and acupotomy group compared with the osteoarthritis group.Western blot results revealed that,compared with the control group,the expression levels of Beclin1,Cath D,and LC3II/LC3I were significantly decreased in the osteoarthritis group(P<0.05),while the expression levels of p-Akt/Akt and p-mTOR/mTOR were significantly increased(P<0.05);compared with the osteoarthritis group,the expression levels of Beclin1,Cath D,and LC3II/LC3I were significantly increased in both the hyaluronic acid group and acupotomy group(P<0.05),while the expression levels of p-Akt/Akt and p-mTOR/mTOR were significantly decreased(P<0.05).To conclude,acupotomy intervention can modulate the PI3K/Akt/mTOR signaling pathway to enhance the autophagic level in chondrocytes,thereby maintaining chondrocyte homeostasis.This ultimately leads to a slowdown in cartilage degeneration.

Objective: To investigate the epidemiological characteristics of varicella outbreaks in primary and middle schools, and to establish a risk predictive model, so as to provide scientific guidance for the prevention of varicella outbreaks in schools. Methods: Based on a nested case-control study, primary and middle schools in 4 districts of Shanghai (Yangpu District and Jingan District) and Hangzhou (Xiaoshan District and Linping District) from January to December 2023 were selected to observe the status of varicella outbreaks. Associated factors of varicella outbreaks were investigated and used for establishing the predictive model, which was evaluated by the Hosmer-Lemeshow(H-L) goodness of fit test, receiver operating characteristic (ROC) curve, Calibration curve, decision curve analysis (DCA). Results: A total of 98 varicella outbreaks were included, with 195 schools without varicella outbreaks during the same period as controls. Eight factors, including the availability of warm water in restroom, availability of hand soap in restroom, average class size, duration of student attendance at school per day, presence of a fulltime school doctor, hesitancy of the school principal towards varicella vaccination, and rates of first and second doses of varicella vaccination, were identified as potential factors for school varicella outbreaks, with statistically significant differences (χ2/Z=10.01, 20.49, 17.43, 9.74, 32.17, 6.60, 2.20, 3.39, P<0.05). The 8 variables above were employed to construct a risk predictive model, and Hosmer-Lemeshow goodness of fit test yielded a χ2 value of 5.863 (P>0.05); the area under the ROC curve (AUC) was 0.846 (95%CI=0.799-0.893); Calibration curve analysis indicated good consistency between predicted and actual values of the model. DCA demonstrated favorable predictive performance of the model over a wide range. Conclusions The predictive model for school varicella outbreaks demonstrates satisfactory accuracy and efficacy. It suggested to make good use of this prediction model and take relevant measures to reduce the risk of varicella transmission in schools.

Objective: To explore joint effects between body fat mass and insulin resistance with dyslipidemia in children, in order to provide scientific evidence for the prevention and treatment of dyslipidemia in children. Methods: Data was derived from the second follow up survey (2021) of the Huantai Childhood Cardiovascular Health Cohort. The complete information of a total of 1 322 children was included in the study. Multivariate Logistic regression model was used to analyze the association among fat mass percentage (FMP), fat mass index (FMI), subcutaneous fat mass (SFM) and visceral fat mass (VFM) and dyslipidemia. Restrictive cubic spline model was used to analyze dose response relationship between levels of each of the four body fat mass indicators and dyslipidemia. Multivariate Logistic regression model was used to analyze the association of interaction of body fat mass indicators and insulin resistance (IR) with dyslipidemia. Results: Boys had higher VFM and fasting plasma glucose (FPG) levels, while FMP, FMI, SFM, total cholesterol (TC), triglycerides (TG), and high density lipoprotein cholesterol (HDL-C) levels were all lower than those of girls ( t/Z =3.22, 2.58, -15.85, -7.35, -6.49, -2.40, -4.05 , -2.40, P <0.05). After adjusting for all covariates, compared with children with normal FMP, those with higher FMP had an increased likelihood of elevated triglyceride levels ( OR =4.26, 95% CI =2.58-7.09) and low HDL-C levels ( OR =4.10, 95% CI =2.51-6.76). FMI, SFM, and VFM observed similar results to FMP ( P <0.05). Additionally, the additive interaction analyses showed that all four indicators of elevated body fat mass interacted with IR, increasing the likelihood of dyslipidemia in children ( P <0.05). There were linear or nonlinear dose response association between each of four body fat mass indicators and dyslipidemia. Conclusions Elevated body fat mass increases the likelihood of dyslipidemia in children, and the likelihood of dyslipidemia further would increase if children have concomitant IR. Therefore, it is necessary to pay more attention to children with elevated body fat mass and IR to prevent the occurrence of dyslipidemia.

This article summarizes Professor TIAN Conghuo's key points and features of acupuncture for primary dysmenorrhea. Professor TIAN believes that the location of dysmenorrhea is in the uterus, and the fundamental pathogenesis is the disharmony of both form and spirit. During clinical treatment, he first conducts abdominal palpation, often detecting cord-like nodules around Guilai (ST 29), Huangshu (KI 16), and Zigong (EX-CA 1). Needling reaches the depth of these nodules. Additionally, the use of four acupoints around the navel (Shuifen [CV 9], bilateral Huangshu (KI 16), and Yinjiao [CV 7]), and four back-shu points (Ganshu [BL 18], Pishu [BL 20], Shenshu [BL 23], and Geshu [BL 17]) is applied to regulate the spirit and strengthen the body. Point selection is further based on syndrome differentiation. The "Three layers" needling technique is used, emphasizing the mental and emotional state of the patients, calming the spirit and regulating qi and blood, to achieve a harmonious treatment of both form and spirit for dysmenorrhea.
