ObjectiveTo observe the clinical efficacy of electroacupuncture in treatment of simple obesity patients and its effects on the metabolism-inflammation network. MethodsSeventy-two patients with simple obesity were randomly divided into a electroacupuncture group and a sham electroacupuncture group， with 36 patients in each group. In the electroacupuncture group， conventional acupuncture was applied at Zhongwan （CV 12）， bilateral Tianshu （ST 25）， bilateral Daheng （SP15）， Qihai （CV 6）， Guanyuan （CV 4）， bilateral Zusanli （ST 36） and Fenglong （ST 40）. The sham electroacupuncture group used placebo needle at same acupoints as the electroacupuncture group. Both groups were given sparse-dense waves with a frequency of 2/10 Hz， 30 minutes per session， 3 times a week， for a total of 8 weeks of treatment. The changes of human body parameters including body weight， body mass index （BMI）， waist circumference， and body fat percentage （BFP）， metabolic factors including serum fasting blood glucose （FBG）， triglyceride （TG）， total cholesterol （TC）， high density lipoprotein （HDL）， low density lipoprotein （LDL）， leptin， and ghrelin， and inflammatory factors including interleukin-6 （IL-6） and tumor necrosis factor α （TNF-α） were compared before and after treatment. Correlations between changes in leptin， ghrelin and inflammatory factors were further analyzed. ResultsWaist circumference was significantly reduced after treatment in both groups compared with baseline （P＜0.05）， and the post-treatment waist circumference was lower in the electroacupuncture group than in the sham electroacupuncture group （P＜0.05）； body weight， BMI and BFP decreased significantly after treatment compared to pretreatment levels in the electroacupuncture group （P＜0.05）. Serum leptin， IL-6 and TNF-α declined significantly after treatment in both groups versus baseline （P＜0.05）； the electroacupuncture group had lower post-treatment levels of leptin， IL-6 and TNF-α as well as larger pre-post changes than the sham group （P＜0.05）； ghrelin increased markedly after treatment in both groups （P＜0.05）， with higher post-treatment ghrelin and greater pre-post variation observed in the electroacupuncture group （P＜0.05）. In the electroacupuncture group， changes in ghrelin were negatively correlated with IL-6 and positively correlated with TNF-α （P＜0.01）； in the sham electroacupuncture group， ghrelin changes were negatively correlated with both IL-6 and TNF-α， whereas leptin changes were positively correlated with the two inflammatory markers （P＜0.01）. ConclusionElectroacupuncture can effectively improve clinical manifestations， as well as regulate serum metabolic and pro-inflammatory factors in patients with simple obesity， and discrepant correlation patterns of metabolism-inflammation are observed between the two groups.

Objective To explore the protective effects of genetically modified porcine erythrocyte suspension as a subnormothermic normoxic mechanical perfusate on hypoxic-ischemic brain injury in cynomolgus monkeys caused by traumatic hemorrhage.Methods Cynomolgus monkeys were randomly divided into positive and negative control groups(a total of 3 monkeys,with 3 left cerebral hemispheres as the positive control group and 3 right cerebral hemispheres as the negative control group)and the subnormothermic perfusion group(n=3).The positive control group was directly sampled 1 hour after circulatory arrest,while the negative control group was placed at subnormothermic conditions for 6 hours after circulatory arrest.The subnormothermic perfusion group underwent 6 hours of subnormothermic normoxic mechanical perfusion of the bilateral common carotid arteries of the cynomolgus monkey hypoxic-ischemic brain injury model using genetically modified porcine erythrocyte suspension 1 hour after circulatory arrest.Before perfusion,cross-matching experiments were conducted between the six genetically modified pig and the cynomolgus monkeys.After the start of perfusion,the levels of routine blood indicators in the perfusate were detected at 0,1,2,3,4,5 and 6 hours.Blood oxygen saturation was recorded,and the levels of Na+,K+,Ca2+,glucose and blood pH in the perfusate were measured,as well as the levels of IgG and IgM in the perfusate.After 6 hours of perfusion,the water content of the brain tissue was measured.Nissl staining was performed on the frontal cortex and hippocampal regions,and immunofluorescence staining was used to detect the expression of glial fibrillary acidic protein(GFAP),ionized calcium-binding adapter molecule 1(Iba1)and neuronal nuclear antigen(NEUN).Results The cross-matching results between the six genetically modified pig and the cynomolgus monkeys were negative.The number of red blood cells in the perfusate decreased significantly at 3 hours of perfusion,and the hemoglobin level showed a downward trend at 1,3,5 and 6 hours.The number of white blood cells and platelets decreased at all time points.The blood oxygen saturation in the subnormothermic perfusion group remained stable at 95%-98%,and the levels of blood oxygen saturation,Na+,Ca2+,glucose and pH were stable,while the K+level first increased and then decreased.There was no significant difference in the levels of IgG and IgM before and after perfusion.The water content of brain tissue at the end of perfusion in the subnormothermic perfusion group was significantly higher than that in the positive control group(P<0.001).Nissl staining results showed that compared with the positive control group,the pyramidal neurons in the prefrontal cortex of the subnormothermic perfusion group maintained better morphological integrity,with no significant increase in enlarged and deformed cells.In the hippocampal CA1 region,there was a slight increase in enlarged and deformed cells,and a few cells with undamaged structures showed reduced cell size.In the hippocampal dentate gyrus,fewer granule neurons had compromised structural integrity,with increased cell edema.NEUN immunofluorescence staining showed that compared with the positive control group,the pyramidal neurons in the prefrontal cortex and hippocampal CA1 region of the subnormothermic perfusion group had better morphological states,with clear axons.The granule cells in the hippocampal dentate gyrus were well preserved,but the nuclei were less well protected.GFAP immunofluorescence staining showed that compared with the positive control group,the subnormothermic perfusion group had sparser protrusions that were more tightly associated with neurons.Iba1 immunofluorescence staining showed that compared with the positive control group,the subnormothermic perfusion group had thicker and fewer protrusions.Conclusions Compared with the positive control group,subnormothermic normoxic mechanical perfusion with genetically modified porcine erythrocyte perfusate increases brain tissue edema in cynomolgus monkeys,but better preserves the morphological integrity of neurons and glial cells.The protective effects may be related to the continuous oxygen and energy supply,maintenance of ion homeostasis and perfusate pH,reduced rejection,and low metabolic state of the whole brain.

Left ventricular hypertrophy(LVH)is one of the common target organ damage of hypertension."Yang leading to qi and yin leading to formation"is the basic form of human material and energy metabolism and disease development.The pathogenesis of hypertension LVH is inseparable from the imbalance of yin and yang.The deficiency of"yang leading to qi"leads to the decline of zang-fu function,deficiency of qi and blood,and the excess of"yin leading to formation"leads to the accumulation of pathological products such as phlegm and fluid,both of which are important pathogenesis of hypertensive LVH.Hypertensive LVH can be seen at the beginning of yin deficiency and yang hyperactivity,liver hyperactivity and wind movement,qi and blood deficiency,and later yin and yang deficiency,phlegm and blood stasis interjunction and other symptoms.In the treatment of hypertensive LVH,the early stage should be based on nourishing yin and extinguishing wind,regulating qi and blood,and the later stage should be based on supplementing yin and yang,expelling phlegm and promoting blood,so as to improve the clinical efficacy of TCM treatment of this disease.

Objective:To analyze the clinical features and genetic sequencing results of a patient with Kallmann syndrome(KS) carrying digenic mutations who initially presented with osteoporosis, and to enhance awareness of this disease phenotype.Methods:Clinical data were collected, and peripheral blood DNA was extracted for whole-exome sequencing. Relevant literature was reviewed to summarize phenotypes associated with digenic/oligogenic variants involving CHD7.Results:The patient exhibited back pain, delayed development of secondary sexual characteristics, and hyposmia. Laboratory tests revealed reduced sex hormones and gonadotropin levels, while pituitary imaging was unremarkable. Bone mineral density imaging confirmed osteoporosis, and thoracolumbar X-rays showed multiple vertebral compression fractures. Genetic analysis identified a heterozygous splice-site mutation in CHD7(c.2698-1G>T) and a heterozygous missense mutation in WDR11(c.439G>A: p.D147N). According to ACMG criteria, the CHD7 mutation was classified as pathogenic, while the WDR11 variant was defined as a variant of uncertain significance(VUS). Literature review indicated that 40% of KS patients with digenic/oligogenic variants involving CHD7 presented with hearing or ocular abnormalities.Conclusion:This study reports a novel CHD7 mutation and a previously undescribed digenic combination of CHD7 and WDR11 variants in a KS patient. CHD7 variants may be implicated in auditory or ocular involvement in KS cases with digenic/oligogenic inheritances. KS patients may also manifest skeletal abnormalities in addition to hypogonadotropic hypogonadism. Tailored management of sex hormones and osteoporosis therapies across life stages is essential for optimizing bone health in KS.

Objective:To conduct a comprehensive review on the current research status of postpartum follow-up for patients with hypertensive disorders of pregnancy (HDP), and provide a basis and guidance for the management of postpartum follow-up for HDP patients.Methods:Guided by the methodological framework of the scoping review, the literatures on postpartum follow-up of HDP patients in Cochrane Library, PubMed, Web of Science, Embase, China Biomedical Literature Database, China National Knowledge Infrastructure, VIP and Wanfang databases were retrieved, and search for relevant literature by the snowballing method. The search time range is from the establishment of the database to February 1, 2025. The included literature was analyzed and summarized.Results:A total of 32 literatures were included, including 31 in English and 1 in Chinese. The participation rate of postpartum follow-up for HDP patients is generally low, and the disease has a significant impact on long-term health. In addition, there is considerable variation in the content, format and time of follow-up. The follow-up content includes the patient's physical health status, long-term health risks and the availability of medical resources, etc.Conclusions:There are still deficiencies in the current implementation of postpartum follow-up for HDP patients. Existing follow-up studies lack high-quality randomized controlled trials as evidence support, and the influencing factors are complex and diverse. In the future, it is necessary to strengthen cooperation among multiple disciplines, closely integrate clinical guidelines with practical needs, and systematically evaluate the effectiveness of follow-up in clinical practice to enhance the scientific and effectiveness of follow-up and provide better health management support for HDP patients.

Autism spectrum disorder(ASD) is a neurodevelopmental disorder, and social impairment was one of the core symptoms of ASD, which can seriously affects the social life of patients.The pathogenesis of social impairment in ASD is unclear and it may involves many brain abnormalities.The related theories and hypotheses are numerous and there is no unified conclusion. Studies have shown that the cerebellum has extensive connections with brain networks and is involved in the regulation of social cognition, but its role in ASD has not been fully emphasized.The structural and functional abnormalities of the cerebellar-cortex (CC) loop in ASD patients can lead to language communication disorders, empathy disorders, difficulties in interpreting social cues, abnormal social reward processing and emotional regulation disorders, which are closely related to ASD social impairment. Noninvasive brain stimulation of the superficial cerebellum can improve the abnormal CC circuit in ASD patients, and the cerebellum can be considered as a target for the treatment of social disorders in ASD in the future.Based on the clinical and basic researches on social impairment in ASD in recent years, this article reviews the relevant manifestations of disorders which cerebellar and CC circuit involved, aiming to promote the development of related research in the future.

Objective:To develop and validate a Self-care Ability Scale for Arteriovenous Fistula (AVF) in Maintenance Hemodialysis (MHD) patients.Methods:Guided by Orem's self-care theory, the initial item pool of the scale was developed through a literature review, semi-structured interviews, and group discussions. The initial scale was finalized after two rounds of expert consultation using the Delphi method. A convenience sampling method was used to recruit 418 MHD patients using AVF in January 2024 for item analysis, exploratory factor analysis and reliability testing. Another 293 MHD patients using AVF were recruited in March 2024 for confirmatory factor analysis.Results:The self-care ability scale for AVF in MHD patients included four dimensions: knowledge and skills of AVF self-care, willingness and attitude toward AVF self-care, recognition and prevention of AVF complications, and patient self-adjustment and adaptation, comprising 38 items. The content validity index at the scale level was 0.98. Exploratory factor analysis extracted four common factors with a cumulative variance contribution rate of 84.706%. Confirmatory factor analysis indicated good model fit, strong convergent validity, and ideal discriminant validity. The total Cronbach's α coefficient of the scale was 0.987; the split-half reliability coefficient was 0.902, and the test-retest reliability coefficient was 0.979.Conclusions:The Self-care Ability Scale for AVF in MHD patients demonstrates excellent reliability and validity, making it a suitable tool for assessing patients' ability to self-care for their AVF.

Objective To explore the relationship between sarcopenia and related indicators and quality of life in the elderly hypertensive population.Methods A total of 104 elderly patients with hypertension who were hospitalized in the Second People's Hospital of Hefei from January to December 2024 were selected as research subjects.The general information,biochemical indicators,blood pressure variability,skeletal muscle mass index,grip strength and walking speed of patients were collected,and the quality of life was evaluated by World Health Organization quality of life-brief version(WHOQOL-BREF).Patients were divided into non-sarcopenia group(n=46)and sarcopenia group(n=58)based on the presence or absence of sarcopenia.The clinical data and quality of life of patients in two groups were compared.Results There were statistically significant differences in gender,age,body mass index,serum albumin,24-hour systolic blood pressure coefficient of vatiation(SCV),24-hour diastolic blood pressure coefficient of vatiation(DCV)and WHOQOL-BREF score between two groups of patients(P＜0.05).Sarcopenia was negatively correlated with the quality of life in the physical and psychological domains(P＜0.05),but not correlated with the quality of life in the social relationship and environmental domains(P＞0.05).Both 24-hour SCV and 24-hour DCV were risk factors for quality of life in the physiological and psychological domains,while serum albumin was a protective factor for the quality of life in the physiological and psychological domains(P＜0.05).Conclusion Sarcopenia,serum albumin,24-hour SCV and 24-hour DCV in elderly hypertensive population are all correlated with the quality of life in the physiological and psychological domains.Attention should be paid to the physical function training of such people,ensuring adequate nutritional intake,actively detecting and reducing blood pressure variability to improve the overall quality of life.
