ObjectiveTo analyze the epidemiological and clinical characteristics of the 21 confirmed monkeypox cases in a district of Chengdu City, and to provide scientific guidance for the prevention and control of subsequent monkeypox epidemics. MethodsData of confirmed monkeypox cases residing in this district were collected from the Disease Control and Prevention Information System of China. A retrospective descriptive epidemiological analysis was used to analyze the demographic, distributional and behavioral characteristics of the cases. ResultsThe first confirmed case of monkeypox was reported on July 5, 2023. Up to April 30, 2025, a total of 21 confirmed cases of monkeypox have been reported. All cases were male, with a mean age of (30.9±6.2) years. The highest proportion of cases(47.62%) was in the 30‒40 years age group. The majority were men who have sex with men (MSM) population (90.48%, 19/21). The results showed that 19.05% of cases were co-infected with HIV, and 19.05% had a history of syphilis infection. Within 21 days prior to symptom onset, 19 cases (90.48%) self-reported engaging in male-to-male sexual contact, among whom 10 cases (52.63%) reported having taken protective measures, while 9 cases (47.37%) did not take safety precautions. Thirteen cases (61.90%) had no travel history to areas with reported monkeypox cases during the 21 days before symptom onset. The predominant manifestation was exanthem (100%, 21/21), followed by fever (57.14%, 12/21) and lymphadenectasis (47.62%, 10/21). Among febrile cases, 50.00% (6/12) had low-grade fever (37.3‒38.0 ℃). All cases were identified through active medical consultation. The median interval from symptom onset to the first medical visit was 3 (2, 6) days, with a maximum interval of 14 days. The median interval from symptom onset to laboratory confirmation was 7 (5, 9) days. Six cases (28.57%) had two or more visits to the hospital, with bacterial infection being the primary initial diagnosis. ConclusionMonkeypox prevention and control efforts in a district of Chengdu City should prioritize MSM population and young and middle-aged adults aged 30 to <40 years. It is recommended to establish an integrated monkeypox epidemic prevention and control network by leveraging existing HIV/AIDS prevention and control network. Concurrently, accelerating the deployment of the national intelligent infectious disease monitoring and early warning front-end software will strengthen early detection capabilities and be beneficial for the overall effectiveness of epidemic prevention and control efforts.

This paper summarizes professor YANG Chunbo's clinical experience in treating refractory constipation （RC） complicated with melanosis coli （MC） from the perspective of damp-heat theory. Internal accumulation of damp-heat is considered as the core pathogenesis of this condition， and the therapeutic principles should focus on clearing， transforming， tonifying， and resolving. Self-formulated Qinghua Beverage （清化饮） is developed to clear and transform damp-heat， regulate qi， and soothe collaterals. In clinical practice， RC complicated with MC is classified into damp-heat with qi stagnation syndrome and damp-heat with stasis obstruction syndrome. Qinghua Beverage is used as the base prescription with modifications according to syndrome differentiation. For damp-heat with qi stagnation syndrome， medicinals that promote qi movement and unblock the bowels， activate blood and clear collaterals are added， while for damp-heat with stasis obstruction syndrome， herbs that resolve stasis and unblock collaterals are incorporated， with simultaneous consideration of nourishing blood and supporting collaterals.

OBJECTIVE: To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI. METHODS: From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients. RESULTS: Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation. CONCLUSION Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

Latent autoimmune diabetes in adults (LADA) is a type of mixed diabetes in WHO2019 Diabetes classification. LADA has both type 1 diabetes and type 2 diabetes genetic susceptibility genes. It is difficult to distinguish LADA from type 1 diabetes mellitus and type 2 diabetes mellitus. This paper systematically reviewed the genetic background and immune characteristics of LADA, providing new ideas for the study of LADA and theoretical support for the precise diagnosis and treatment of LADA and immune intervention strategies.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

OBJECTIVE: To investigate the relationship between peripheral blood circular RNA Bardet-Biedl syndrome 9 (circBBS9) and circRNA catenin beta 1 (circCTNNB1) and weaning failure of mechanical ventilation in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). METHODS: A prospective, observational cohort study was conducted. The patients with AECOPD who received invasive mechanical ventilation and passed the spontaneous breathing test (SBT) admitted to the First Affiliated Hospital of Hebei North University from January 2022 to February 2024 were selected as the study subjects. According to the outcome of weaning, the patients were divided into failed weaning group and successful weaning group. At admission and before SBT, the expression levels of circBBS9 and circCTNNB1 in peripheral blood were detected by fluorescence quantitative polymerase chain reaction (PCR). General information, acute physiology and chronic health evaluation II (APACHEII) score within 24 hours of admission, vital signs before SBT and the most recent laboratory indicators before SBT of the patients were collected. The differences in circBBS9 and circCTNNB1 expression levels and clinical data between the two groups were compared. Multivariate Logistic regression was used to analyze the influencing factors of the weaning failure. Receiver operator characteristic curve (ROC curve) was used to analyze the predictive value of each index on weaning failure. RESULTS: Ultimately, 132 patients with AECOPD who underwent invasive mechanical ventilation and passed the SBT were enrolled in the study. Among them, 82 patients were successfully weaned from mechanical ventilation, while 50 patients failed to be weaned, resulting in a weaning failure rate of 37.88%. There was no statistically significant difference in the expression levels of circBBS9 and circCTNNB1 in the peripheral blood at admission of patients between the two groups. The expression level of circBBS9 in the peripheral blood before SBT of patients in the failed weaning group was significantly higher than that in the successful weaning group (2^-ΔΔCt: 131.64±30.24 vs. 100.00±21.32), and the expression level of circCTNNB1 was significantly lower than that in the successful weaning group (2^-ΔΔCt: 79.90±16.82 vs. 100.00±26.43), and the differences were statistically significant (both P < 0.05). The APACHEII score within 24 hours of admission and the levels of RSBI, SCr, and PCT before SBT in the failed weaning group were significantly higher than those in the successful weaning group [APACHEII score: 22.54±4.62 vs. 16.56±4.58, RSBI: 81.90±16.56 vs. 63.25±17.00, SCr (μmol/L): 100.20±17.27 vs. 89.93±26.29, PCT (μg/L): 1.08±0.18 vs. 0.87±0.22], and the Alb level before SBT was significantly lower than that in the successful weaning group (g/L: 29.71±2.73 vs. 33.93±2.89), and the differences were statistically significant (all P < 0.05). There was no statistically significant difference in other clinical data between the two groups. Multivariate Logistic regression analysis showed that circBBS9 [odds ratio (OR) = 1.291, 95% confidence interval (95%CI) was 1.049-1.588] and APACHEII score (OR = 2.897, 95%CI was 1.004-8.353), RSBI (OR = 1.413, 95%CI was 1.057-1.890) were independent risk factors for weaning failure (all P < 0.05), and circCTNNB1 (OR = 0.812, 95%CI was 0.688-0.959) and Alb (OR = 0.149, 95%CI was 0.036-0.614) were protective factors (both P < 0.05). ROC curve analysis showed that circBBS9, circCTNNB1, APACHEII score, RSBI, and Alb all had certain value for predicting weaning failure. The area under the ROC curve (AUC) and 95%CI were 0.820 (0.750-0.890), 0.755 (0.674-0.835), 0.827 (0.757-0.897), 0.795 (0.715-0.876), and 0.854 (0.791-0.919), respectively. Using the multivariate Logistic regression equation as the combined indicator, the AUC for predicting weaning failure reached 0.997 (95%CI was 0.993-1.000), which was significantly higher than that of the single indicators including circBBS9, circCTNNB1, APACHEII score, RSBI, and Alb (the Z value was 5.582, 6.093, 5.771, 5.932, and 5.182, respectively, all P < 0.05). CONCLUSIONS High expression of circBBS9 and low expression of circCTNNB1 in the peripheral blood of AECOPD patients receiving invasive mechanical ventilation before SBT are associated with weaning failure. circBBS9, circCTNNB1 combined with APACHEII score, RSBI and Alb are helpful for predicting the failure of weaning in these patients.
