Objective To analyze the epidemiological characteristics and epidemic situation of children with Kashin-Beck disease (KBD) in China,and provide the basis for formulating prevention and control measures. Methods Fixed-point monitoring,moving-point monitoring,and full coverage of monitoring were promoted successively from 1990 to 2023. Some children (7-12 years old) underwent clinical and right-hand X-ray examinations every year. According to the KBD diagnosis criteria,clinical and X-ray assessments were used to confirm the diagnosis. Results In 1990,the national KBD detectable rate was 21.01％. X-ray detection decreased to below 10％ in 2003 and below 5％ in 2007. Between 2010 and 2018,the prevalence of KBD in children was less than 0.4％,which fluctuated at a low level,and has decreased to 0％ since 2019. Spatial epidemiological analysis indicated a spatial clustering of adult patients prevalence rate in the KBD areas. Conclusion The evaluation results of the elimination of KBD in China over the last 5 years showed that all villages in the monitored areas have reached the elimination standard. While the adult KBD patients still need for policy consideration and care.

The discoid meniscus is a common congenital meniscal malformation that is prevalent mainly in Asians and of-ten occurs in the lateral discoid meniscus.Patients with asymptomatic discoid meniscus are usually treated by conservative methods such as observation and injury avoidance,while patients with symptoms and tears need to be treated surgically.Arthroscopic saucerization combined with partial meniscectomy and meniscus repair is the most common surgical approach.,and early to mid-term reports are good.The prognostic factors are the patient's age at surgery、follow-up time and type of surgery.Some patients experience complications such as prolonged postoperative knee pain,early osteoarthritis,retears and Osteochondritis dissecans.The incidence of prolonged postoperative knee pain was higher and the incidence of Osteochondritis dissecans was the lowest.Retears of the lateral meniscus is the main reason for reoperation.

Objective:To explore the correlation of bone marrow polychonal plasma cell proportion (pPC% ) and clinical features in newly diagnosed multiple myeloma (NDMM) patients.Methods:A retrospective analysis of 317 patients with NDMM admitted to Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2018 to January 2023 was performed. The results of the pPC% in all patients were clear. The relationship between the pPC% and clinical characteristics was analyzed.Results:A total of 317 patients were included, comprising 180 males and 137 females. The median age at diagnosis was 61 (26-91) years, and 55.8% were 60 years or older. The pPC% in the bone marrow of patients with NDMM was different in the DS, International Staging System (ISS), and revised ISS (R-ISS) stages ( P=0.002, 0.010, and 0.049, respectively), whereas no statistical difference in pPC% was observed among patients with different FISH risk stratigrams ( P=0.971). The correlation coefficient between pPC% and hemoglobin (HGB) at the first diagnosis in patients was 0.211 ( P<0.01). The correlation coefficients with serum calcium, serum creatinine, M protein level, and β 2-microglobulin were -0.141, -0.120, -0.181, and -0.207, respectively, and the results of the significance test were P=0.012, 0.033, 0.004, and 0.002, respectively, indicating a negative correlation. Compared with the patients with a pPC% of ≥2.5%, the group of patients with a pPC% of <2.5% had significantly higher levels of light chain, serum calcium, serum creatinine, M protein, and β 2-microglobulin at the initial diagnosis ( P<0.05) ; lower HGB level ( P<0.001) ; and a higher proportion of patients in ISS stage Ⅲ ( P=0.034) . Conclusion:In this study, the pPC% in patients with NDMM was associated with clinical features of good prognosis, including higher HGB, lower serum calcium, serum creatinine, M protein quantity, β 2-microglobulin, light chain involvement, lower proportion of advanced disease (DS stage and ISS stage Ⅲ), and clinical features showing lower tumor burden.

Most patients with stroke experience obstructive sleep apnea (OSA), which has a negative impact on functional outcome and cognitive function in patients with stroke and is associated with increased mortality. Continuous positive airway pressure (CPAP) is a gold standard for treating OSA. This article reviews the effect of CPAP on functional outcome and cognitive function in stroke patients with OSA.

Objective To explore the effect of mindfulness training on mental health of elite athletes and its possible mechanism.Methods Totally 462 Chinese elite athletes(Mage=18.16,SD=3.14,Range=12～28,44.8%female)were conducted a cross-sectional questionnaire survey.SPSS23 was employed for data statistical analysis,and the mediation model was tested through the Bootstrap program of the extension program PROCESS.Results Mindfulness significantly and negatively predicted anxiety(β=-0.386,P<0.001),depression(β=-0.342,P<0.001),and poor sleep quality(β=-0.324,P<0.001),but significantly and positively predicted training&competition satisfaction(β=0.432,P<0.001)and psychological well-being(β=0.399,P<0.001).Moreover,mindfulness showed significant effects on anxi-ety,poor sleep quality,and satisfaction to training and competition through experiential acceptance,cognitive defusion,and decentering.However,it performed significant impacts on their depression and psychological well-being only through experiential acceptance and cognitive defusion.Conclusion Mind-fulness directly predicts negative reactions such as anxiety,depression and poor sleep quality,as well as positive ones including training and competition satisfaction and psychological well-being in elite ath-letes.Moreover,it has indirect effects on anxiety,poor sleep and training and competition satisfaction through experiential acceptance,cognitive defusion and decentering,together with on depression and psychological well-being through the former two factors.

Objective To investigate the pathological damage to and inflammation of different intestinal segments in a rat model of severe hemorrhage,and to explore the effect of polarization of intestinal macrophage on the pathophysiology of intestinal inflammation.Methods Male Wistar rats were randomly divided into two groups:the sham operation group and hemorrhage group.In the hemorrhage group,40％of the total blood volume was lost in 25-30 minutes,while in the sham operation group,only the femoral artery and vein were intubated without bleeding.The rats were killed at 0,3,6,12 and 24 hours.The entire intestine was isolated quickly,and sections of the intestine were cut at the duodenum,jejunum,ileocecal junction,colon and rectum for histopathological evaluation.ELISA was adopted to determine related inflammation factors while multi-color immunohistochemistry was used to calculate macrophage surface markers.The data was statistically analyzed.Results(1)Compared with the sham group,there was no significant difference in colon histology at 3 h and 6 h,but significant difference was detected in rectum scores only at 24 h.The scores of other intestinal segments were significantly different at each time point.The severity of ileocecal and colonic lesions after bleeding increased with time.The duodenum,jejunum and ileocecum were more critically injured at 3 h than the rectum at 6 h.The injury to the duodenum,jejunum,ileum and colon was much more pronounced than to the rectum at 12 h.(2)The expressions of TNF-α and IL-1β in the rectum were increased significantly at 12 h post operation.The expressions of IL-1β,TNF-α in the jejunum increased obviously at 3 h and 6 h,respectively.(3)Three hours after severe bleeding,the level of macrophages in the jejunum and ileocececal area increased significantly,and the percentage of M1 macrophages was higher.After 6 hours,the proportion of M2 macrophages in the jejunum and M1 macrophages decreased significantly.After 3 hours,the percentage of M1 macrophages in the colon decreased,but that of M2 macrophages increased.The proportion of M2 polarized macrophages in the duodenum and rectum increased at 3 h after severe bleeding but decreased at 6 h.Conclusion Pathological damage to intestinal sections after bleeding varies depending on the time,and is correlated with the inflammatory level of macrophages.

Objective:To investigate the dynamic prevalence of Kashin-Beck disease (KBD) in 2020, and to provide the basis for assessment of KBD control and elimination.Methods:According to the "Kashin-Beck Disease Monitoring Plan (2019 Edition)", collection of basic information of endemic areas and children KBD examination were executed in all endemic areas from every endemic county (city, district, banner) of 13 endemic provinces. All children aged 7 - 12 years in endemic areas underwent clinical examination, X-ray examination was performed for clinically positive children. According to the criteria of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010), KBD cases were diagnosed by both clinical examination and X-ray check.Results:In monitoring of 827 986 children of 7 - 12 years old, a total of 703 children with similar clinical signs of KBD were suspected positive cases. X-ray results showed that 703 children were normal, with no X-ray positive change, they were not children KBD cases.Conclusions:In 2020, no cases of Kashin-Beck disease are detected in children nationwide, and the condition of Kashin-Beck disease in children nationwide continues to be at a level of elimination.

Objective:To investigate the diagnostic method and value of echocardiography in screening right patent ductus arteriosus(PDA) of infants.Methods:This was a prospective study.Thirty-one infants with right PDA diagnosed by ultrasound and confirmed by prenatal ultrasonography, electronic computed tomography angiography, angiocardiography and/or surgery in Hebei Children′s Hospital from April 2014 to May 2022 were collected as research subjects, and the association of right ductus arteriosus with aortic arch anomalies and complex cardiac malformations were summarized. The diagnostic method and value of ultrasonic screening were summed up.Results:Of the 31 cases, 30 cases were correctly diagnosed by ultrasound and 1 case was misdiagnosed, who was a left aortic arch descending to the right, a crossover variation of the right and left pulmonary arteries, and a rightward displacement of the ductus arteriosus. Among these cases diagnosed correctly, 27 cases (including 24 cases with right aortic arch and 3 cases with left aortic arch) presented that ductus arteriosus was open and its ostium of pulmonary artery end was located in the proximal right pulmonary artery in views of parasternal short-axis view of great vessels at cardiac base with the combination of two dimensions and color Doppler flow imaging. Other 3 cases of right aortic arch were all single ventricle with transposition of the great artery. Due to the parallel relationship of the two great arteries, the standard parasternal short-axis view of great vessels could not be obtained, and the right ductus arteriosus was found in the high parasternal views.In all of the 27 cases with right aortic arch and right ductus arteriosus, high parasternal views showed that one end of the ductus arteriosus was connected to the right aortic arch isthmus and the other end was connected to the right pulmonary artery. In all of the 3 cases with left aortic arch and right ductus arteriosus, the high parasternal views showed that one end of the ductus arteriosus was connected to the right subclavian artery and the other end was connected to the right pulmonary artery. Among the 27 cases with right aortic arch, 16 cases were accompanied with mirror image branches, 9 cases of which had complex cardiac malformations; 10 cases were associated with aberrant left subclavian artery, 1 case of which had complex cardiac malformations; 1 case was with isolated left subclavian artery, and without complex cardiac malformations. All 3 cases of left aortic arch were accompanied with isolated right subclavian artery and none of them were associated with complex cardiac malformations. Clinical outcomes of 30 cases with right PDA: 14 cases underwent ductus arteriosus ligation due to thick ductus or other heart malformations. In other 16 cases, 4 cases were closed spontaneously, 9 cases had persistent small ductus arteriosus, and 3 cases were lost to follow-up.Conclusions:Right ductus arteriosus is mostly related to the right aortic arch, and those with mirror image branches are prone to complex cardiac malformations; cases of left aortic arch with right ductus arteriosus are tend to accompany isolated right subclavian artery. Ultrasound has an important application in the screening and diagnosis of right PDA.

OBJECTIVE: To investigate the factors related to renal impairment in patients with diabetic kidney disease (DKD) from the perspective of integrated Chinese and Western medicine. METHODS: Totally 492 patients with DKD in 8 Chinese hospitals from October 2017 to July 2019 were included. According to Kidney Disease Improving Global Outcomes (KDIGO) staging guidelines, patients were divided into a chronic kidney disease (CKD) 1-3 group and a CKD 4-5 group. Clinical data were collected, and logistic regression was used to analyze the factors related to different CKD stages in DKD patients. RESULTS: Demographically, male was a factor related to increased CKD staging in patients with DKD (OR=3.100, P=0.002). In clinical characteristics, course of diabetes >60 months (OR=3.562, P=0.010), anemia (OR=4.176, P<0.001), hyperuricemia (OR=3.352, P<0.001), massive albuminuria (OR=4.058, P=0.002), atherosclerosis (OR=2.153, P=0.007) and blood deficiency syndrome (OR=1.945, P=0.020) were factors related to increased CKD staging in patients with DKD. CONCLUSIONS Male, course of diabetes >60 months, anemia, hyperuricemia, massive proteinuria, atherosclerosis, and blood deficiency syndrome might indicate more severe degree of renal function damage in patients with DKD.

Objective: To study the diagnostic value of different detection markers in histological categories of endocervical adenocarcinoma (ECA), and their assessment of patient prognosis. Methods: A retrospective study of 54 patients with ECA in the Cancer Hospital, Chinese Academy of Medical Sciences from 2005-2010 were performed. The cases of ECA were classified into two categories, namely human papillomavirus-associated adenocarcinoma (HPVA) and non-human papillomavirus-associated adenocarcinoma (NHPVA), based on the 2018 international endocervical adenocarcinoma criteria and classification (IECC). To detect HR-HPV DNA and HR-HPV E6/E7 mRNA in all patients, we used whole tissue section PCR (WTS-PCR) and HPV E6/E7 mRNA in situ hybridization (ISH) techniques, respectively. Additionally, we performed Laser microdissection PCR (LCM-PCR) on 15 randomly selected HR-HPV DNA-positive cases to confirm the accuracy of the above two assays in identifying ECA lesions. Receiver operating characteristic (ROC) curves were used to analyze the efficacy of markers to identify HPVA and NHPVA. Univariate and multifactorial Cox proportional risk model regression analyses were performed for factors influencing ECA patients' prognoses. Results: Of the 54 patients with ECA, 30 were HPVA and 24 were NHPVA. A total of 96.7% (29/30) of HPVA patients were positive for HR-HPV DNA and 63.3% (19/30) for HR-HPV E6/E7 mRNA, and 33.3% (8/24) of NHPVA patients were positive for HR-HPV DNA and HR-HPV E6/E7 mRNA was not detected (0/24), and the differences were statistically significant (P<0.001). LCM-PCR showed that five patients were positive for HR-HPV DNA in the area of glandular epithelial lesions and others were negative, which was in good agreement with the E6/E7 mRNA ISH assay (Kappa=0.842, P=0.001). Analysis of the ROC results showed that the AUC of HR-HPV DNA, HR-HPV E6/E7 mRNA, and p16 to identify HPVA and NHPVA were 0.817, 0.817, and 0.692, respectively, with sensitivities of 96.7%, 63.3%, and 80.0% and specificities of 66.7%, 100.0%, and 58.3%, respectively. HR-HPV DNA identified HPVA and NHPVA with higher AUC than p16 (P=0.044). The difference in survival rates between HR-HPV DNA (WTS-PCR assay) positive and negative patients was not statistically significant (P=0.156), while the difference in survival rates between HR-HPV E6/E7 mRNA positive and negative patients, and p16 positive and negative patients were statistically significant (both P<0.05). Multifactorial Cox regression analysis showed that International Federation of Obstetrics and Gynecology (FIGO) staging (HR=19.875, 95% CI: 1.526-258.833) and parametrial involvement (HR=14.032, 95% CI: 1.281-153.761) were independent factors influencing the prognosis of patients with ECA. Conclusions: HR-HPV E6/E7 mRNA is more reflective of HPV infection in ECA tissue. The efficacy of HR-HPV E6/E7 mRNA and HR-HPV DNA (WTS-PCR assay) in identifying HPVA and NHPVA is similar, with higher sensitivity of HR-HPV DNA and higher specificity of HR-HPV E6/E7 mRNA. HR-HPV DNA is more effective than p16 in identifying HPVA and NHPVA. HPV E6/E7 mRNA and p16 positive ECA patients have better survival rates than negative.
