OBJECTIVES: To investigate the application value of thromboelastography (TEG) in assessing coagulation function in children with severe hemophilia A (HA) after emicizumab (EMI) therapy. METHODS: A retrospective analysis was performed on the activated partial thromboplastin time (APTT) and TEG testing results of 17 children with severe HA before and after EMI treatment at Shenzhen Children's Hospital from January 2023 to July 2024. Correlation analysis was conducted between coagulation factor VIII (FVIII) equivalent activity and reaction time (R value) measured by TEG. RESULTS: After EMI treatment, the mean bleeding rate for children with severe HA was 1.6 events per year, with 15 children (88%) without spontaneous bleeding or joint bleeding. The children with severe HA showed a significant reduction in APTT after EMI treatment (P<0.05), with a significantly shorter APTT than the normal control group (P<0.05). There was no correlation between APTT and FVIII equivalent activity after treatment (P>0.05). After EMI treatment, TEG parameters, including R value, kinetic time, alpha angle (α), maximum amplitude, clot strength, and coagulation index, shifted from a hypocoagulable state before treatment to a nearly normal state after treatment (P<0.05). The R value demonstrated a strong negative correlation with FVIII equivalent activity (r=-0.758, P<0.05). CONCLUSIONS The bleeding condition of children with severe HA can be effectively controlled after EMI treatment. Routine APTT testing cannot reflect true coagulation function, whereas TEG testing is clinically valuable in assessing the coagulation function of children with severe HA undergoing EMI treatment.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the role of diffusion tensor imaging (DTI) in monitoring prognosis after contralateral C7 nerve transfer in patients with central paralysis.Methods:The clinical data of a 56-year-old male patient with right limb motor impairment after cerebral infarction, admitted to the Department of Neurosurgery at Brain Hospital of Hunan Province in October 2023, were retrospectively analyzed. The patient had experienced right limb motor dysfunction for over 2 years following a cerebral infarction and was treated with contralateral C7 nerve transfer. Follow-ups were conducted at 2 and 6 months postoperatively. Motor function was assessed using the Fugl-Meyer Assessment (FMA) and Activities of Daily Living (ADL) scale, while changes in fractional anisotropy (FA) in the lesion area and corticospinal tract were monitored via DTI.Results:Postoperative follow-up of patient showed: (1) Significant improvement in motor function: ADL scores increased from 65 preoperatively to 75 (2 months postop) and 80 (6 months postop); FMA scores increased from 46 to 58 (2 months postop) and 61 (6 months postop). Muscle tension in the affected upper limb decreased markedly, and range of motion in the right shoulder joint improved. (2) Imaging improvements: DTI revealed an increase in FA values from 0.157 to 0.174 in the lesion area and from 0.52 to 0.53 in the corticospinal tract, indicating partial restoration of neural tract integrity.Conclusions:Contralateral C7 nerve transfer can effectively improve motor function in stroke patients. DTI technology provides an objective imaging basis for clinically assessing functional recovery by quantitatively evaluating changes in neural tract integrity, demonstrating significant value in guiding rehabilitation.

Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.

Objective:Analysis of subtype distribution characteristics of human papillomavirus (HPV) infection, pathological findings of HPV-positive patients operated colposcopy and cervical histopathological examination in Changsha from 2020 to 2022.Methods:Retrospective analysis of HPV infection status of 60 354 patients was treated in the First Affiliated Hospital of Hunan University of Chinese Medicine from Jan. 2020 to Oct. 2022. They were divided into<25 years old group (3 250 cases), 25-34 years old group (19 406 cases), 35-44 years old group (17 297 cases), 45-54 years old group (13 104 cases), 55-64 years old group (4 793 cases) and≥65 years old group (2 504 cases). Cervical exfoliated cells were collected from women and specimen of lesion site were collected from men. HPV genotyping detection used polymerase chain reaction (PCR) and flow fluorescence hybridization, which could detect 27 HPV genotypes. Analyze the distribution of HPV subtypes in patients of different age groups and different treatment departments. Analyze the relationship between the infection of HPV subtypes and the outcome of 224 patients with HPV positive who also underwent colposcopy and cervical histopathology. Pearson correlation test was used for correlation analysis, and two-tailed P<0.05 was statistically significant; Pearson chi-square test or continuous correction chi-square test was used to compare the rates between groups, and two-tailed P<0.05 was statistically significant; Chi-square split test was used to compare multiple sample rates. The standard test was corrected according to the number of groups and then compared. The difference was statistically significant when the two-tailed P value was less than the corrected standard test. Results:The overall positive rate of HPV was 16.4% (9 909/60 354). Among all HPV positive patients, affection of single type HPV accounted for 75.5% (7 479/9 909) and affection of multi-type HPV accounted for 24.5% (2 430/9 909). The top six HPV types with infection rates from high to low were: HPV52 22.8% (2 256/9 909), HPV58 11.1% (1 097/9 909), HPV53 10.5% (1 045/9 909), HPV16 9.0% (890/9 909), HPV61 7.8% (774/9 909) and HPV6 7.6% (750/9 909). The difference of overall infection rate between different age groups was statistically significant (χ 2=536.90, P<0.001). The HPV infection rate was the highest in the<25 years old group, 30.1% (978/3 250), and it is higher than the age groups of 25-34 years old, 15.6% (3 035/19 406), group of 35-44 years old, 14.2% (2 464/17 297), group of 45-54 years old, 16.1% (2 115/13 104), group of 55-64 years old, 19.1% (915/4 793) and group of≥65 years old, 16.1% (402/2 504), with statistical significance( P<0.001 respectively). The most common types of HPV infection were type 6, 16.7% (378/2 266) and type 11, 10.5% (239/2 266) in dermatology clinics. The positive rate of HPV16 accounted for 12/17 in cervical intraepithelial neoplasia (CIN) 3 and cervical cancer cases, it was significantly higher than that in the inflammatory cases, 25.0% (35/140) and CIN1 cases, 23.0% (11/48), the statistical values were χ 2=15.02, P<0.001 and χ 2=12.48, P<0.001, respectively, all of which were statistically significant. Conclusions:HPV infection rate is highest in young people under 25 years old. Low-risk HPV6 and 11 are the main types of skin and venereal diseases. Among the total cases, high-risk HPV52, 58 and 53 are the most common types of infection with women in Changsha. However, high-grade cervical intraepithelial neoplasia and cervical cancer are more closely related to HPV16 infection.
