Objective: To investigate the association of the joint effect of body fat levels and dyslipidemia with cardiovascular structural abnormalities in children, so as to provide a scientific reference for the early prevention of cardiovascular damage. Methods: Based on the data from the second follow up (October 2021 to January 2022) of the Huantai Children Cardiovascular Health Follow up Cohort, 1 308 children with complete data were included. The fat mass percentage (FMP), fat mass index (FMI), subcutaneous fat mass (SFM) and visceral fat mass (VFM), left ventricular mass index (LVMI), relative wall thickness (RWT), thickening of carotid intima-media thickening (cIMT) , left ventricular hypertrophy (LVH) and left ventricular geometric remodeling (LVG), triglyceride (TG), total cholesterol (TC) ,high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were obtained. Multivariable Logistic regression model was used to analyze the associations of FMP, FMI, SFM and VFM with thickening of cIMT, LVH and LVG. The joint effects of these body fat indicators and dyslipidemia on the aforementioned cardiovascular outcomes were further explored. Restricted cubic spline model was used to examine the dose response relationships between body fat levels and cardiovascular structural abnormalities. Results: Elevated body fat levels were significantly associated with an increased risk of cardiovascular structural abnormalities, exhibiting J shaped dose response relationships (all P <0.05). Compared with the group with normal body fat and normolipidemia, the risks of thickening of cIMT, LVH, and LVG in the group with elevated FMP combined with dyslipidemia were higher[ OR (95% CI )=11.70 (6.49-21.27), 5.53 (2.97-10.17), 2.33 (1.30-4.05)]; in the group with elevated FMI combined with dyslipidemia, the corresponding risks were higher[ OR (95% CI )= 11.68 (6.43-21.38), 6.98 (3.73-12.92), 2.65 (1.50-4.61)]; in the group with elevated SFM combined with dyslipidemia, the corresponding risks were higher[ OR (95% CI )=10.55 (5.83-19.24), 5.11 (2.71-9.45), 1.99 (1.11- 3.46 )]; and in the group with elevated VFM combined with dyslipidemia, the corresponding risks were higher[ OR (95% CI )=12.44 (6.76-23.14), 6.17 ( 3.31 -11.38), 2.30 (1.30-3.99)] (all P <0.05). Sex stratified analyses showed that the risk of thickening of cIMT in the combined exposure group of all four body fat indicators and dyslipidemia was significantly higher in girls than in boys (all P <0.01). Conclusions Elevated body fat levels and dyslipidemia have a combined effect in children, collectively increasing the risk of cardiovascular structural abnormalities. Prevention of cardiovascular damage in children should focus on both adiposity management and blood lipid regulation.

ObjectiveTo explore the dose-effect relationship and safety of high， medium， and low doses of raw Astragali Radix in the modified Huangqi Chifengtang （MHCD） for treating proteinuria in immunoglobulin A （IgA） nephropathy， and to provide scientific evidence for the clinical use of high-dose Astragali Radix in the treatment of proteinuria in IgA nephropathy. MethodsA total of 120 patients with IgA nephropathy， diagnosed with Qi deficiency and blood stasis combined with wind pathogen and heat toxicity， were randomly divided into a control group and three treatment groups. The control group received telmisartan combined with a Chinese medicine placebo， while the treatment groups were given telmisartan combined with MHCD containing different doses of raw Astragali Radix （60， 30， 15 g）. Each group contained 30 patients， and the treatment period was 12 weeks. Changes in 24-hour urinary protein （24 hUTP）， traditional Chinese medicine （TCM） syndrome scores， effective rate， and renal function were observed before and after treatment. Safety was assessed by monitoring liver function and blood routine. ResultsAfter 12 weeks of treatment， 24 hUTP significantly decreased in the high， medium， and low-dose groups， as well as the control group （P<0.05， P<0.01）. The TCM syndrome scores in the high， medium， and low-dose groups also significantly decreased （P<0.01）. Comparisons between groups showed that the 24 hUTP in the high-dose group was significantly lower than in the medium， low-dose， and control groups （P<0.05， P<0.01）， and the 24 hUTP in the medium-dose group was significantly lower than in the control group （P<0.05）. The TCM syndrome scores in the high and medium-dose groups were significantly lower than in the low-dose and control groups （P<0.05， P<0.01）. The total effective rates for proteinuria in the high， medium， low-dose， and control groups were 92.59% （25/27）， 85.19% （23/27）， 60.71% （17/28）， and 57.14% （16/28）， respectively. The effective rates in the high and medium-dose groups were significantly higher than in the low-dose and control groups （χ²=13.185， P<0.05， P<0.01）. The effective rates for TCM syndrome scores in the high， medium， low-dose， and control groups were 88.89% （24/27）， 81.48% （22/27）， 71.43% （20/28）， and 46.43% （13/28）， respectively. The efficacy of TCM syndrome scores in the high and medium-dose groups was significantly higher than in the control group （χ²=14.053， P<0.01）. Compared with pre-treatment values， there was no statistically significant difference in eGFR and serum creatinine in the high and medium-dose groups. However， eGFR significantly decreased in the low-dose and control groups after treatment （P<0.05）， and serum creatinine levels increased significantly in the control group （P<0.05）. No statistically significant differences were observed in urea nitrogen， uric acid， albumin， total cholesterol， triglycerides， liver function， and blood routine before and after treatment in any group. ConclusionThere is a dose-effect relationship in the treatment of IgA nephropathy with high， medium， and low doses of raw Astragali Radix in MHCD. The high-dose group exhibited the best therapeutic effect and good safety profile.

Background Other infectious diarrhea (OID) refers to infectious diarrhea other than cholera, dysentery, and typhoid/paratyphoid fever. In the global climate change context, frequent extreme temperature events pose a significant threat to population health, yet the association between extreme temperatures and OID remains unclear. Objective To understand the impact of extreme temperature events on the incidence of OID in Taizhou region, and provide a scientific basis for formulating targeted public health intervention strategies. Methods Case data of OID from 2016 to 2024 and meteorological and pollutant data of Taizhou, Zhejiang during the same period were collected. The case data were derived from National Notifiable Infectious Diseases Reporting System, while the meteorological data and pollutant data were obtained from National Meteorological Science Data Center and Taizhou Ecology and Environment Bureau, respectively. An extreme heat event is defined as a period of two or more consecutive days in the warm season during which the daily mean temperature exceeds the 90th percentile value for that season. Similarly, an extreme cold event is defined as a period of two or more consecutive days in the cold season during which the daily mean temperature falls below the 10th percentile value. A distributed lag nonlinear model based on Poisson regression was used to assess the impact of extreme temperatures on OID incidence. Furthermore, subgroup analyses were conducted by gender and age. Results From 2016 to 2024, a total of 108 670 OID cases were reported in Taizhou, with higher incidence in males (61 253 cases) than females (47 417 cases). In terms of single-day lag effect, exposure to extreme cold presented an inverted U-shaped risk pattern: a significant risk effect began to emerge on the 4th day after exposure, continued to rise, and reached a peak on the 7th day (RR=1.044, 95%CI: 1.029, 1.058), whereas extreme heat had no significant impact. In terms of cumulative lag effect, exposure to extreme cold presented a J-shaped cumulative effect curve: short-term exposure (0-2 days) showed no risk effect, but as time extended (0-9 days), a risk effect emerged and reached the maximum risk value during the 0-12 d cumulative period (RR=1.243, 95%CI: 1.057, 1.461). In contrast, extreme heat had no cumulative lag effect. The subgroup analysis revealed that under extreme cold exposure, the single-day lag effects for both males and females exhibited an inverted U-shaped curve, with the risk peaking on day 7 for males (RR=1.045, 95%CI: 1.026, 1.065) and day 8 for females (RR=1.041, 95%CI: 1.019, 1.064). The risk pattern in the 1-5 years age group was similar to that of the overall population but with a higher effect size (RR=1.063, 95%CI: 1.041, 1.085). In terms of the cumulative lag effects, the cumulative risk curves for both males and females under extreme cold exposure showed a J-shaped pattern with varied risk profiles. Significant variations in risk patterns were observed across different age groups. No significant cumulative lag effects were observed for extreme heat exposure in any subgroup. Conclusion Extreme cold can increase the incidence of OID in Taizhou, and the risk effects are heterogeneous among different groups. No risk effect is observed for extreme heat.

Purpose: Erectile dysfunction (ED) is a common male sexual dysfunction. Gut microbiota plays an important role in various diseases. To investigate the effects and mechanisms of intestinal flora dysregulation induced by high-fat diet (HFD) on erectile function. Materials and Methods: Male Sprague–Dawley rats aged 8 weeks were randomly divided into the normal diet (ND) and HFD groups. After 24 weeks, a measurement of erectile function was performed. We performed 16S rRNA sequencing of stool samples. Then, we established fecal microbiota transplantation (FMT) rat models by transplanting fecal microbiota from rats of ND group and HFD group to two new groups of rats respectively. After 24 weeks, erectile function of the rats was evaluated and 16S rRNA sequencing was performed, and serum samples were collected for the untargeted metabolomics detection. Results: The erectile function of rats and the species diversity of intestinal microbiota in the HFD group was significantly lower, and the characteristics of the intestinal microbiota community structure were also significantly different between the two groups. The erectile function of rats in the HFD-FMT group was significantly lower than that of rats in the ND-FMT group. The characteristics of the intestinal microbiota community structure were significantly different. In the HFD-FMT group, 27 metabolites were significantly different and they were mainly involved in the several inflammation-related pathways. Conclusions Intestinal microbiota disorders induced by HFD can damage the intestinal barrier of rats, change the serum metabolic profile, induce low-grade inflammation and apoptosis in the corpus cavernosum of the penis, and lead to ED.

OBJECTIVE To observe the clinical efficacy of donafenib combined with programmed death-1 （PD-1） inhibitors and vascular intervention therapy in the treatment of unresectable hepatocellular carcinoma （HCC）. METHODS This retrospective study included 165 patients with unresectable HCC who were treated at the Fourth and First Affiliated Hospitals of Soochow University between June 2022 and March 2023. Among them， 89 patients received PD-1 inhibitors （tislelizumab or sintilimab， similarly hereinafter） plus vascular intervention （control group） and 76 patients received donafenib in combination with PD-1 inhibitors and vascular intervention （observation group）. Short-term efficacy （3 months after treatment）， long-term efficacy （2 years after treatment）， the levels of liver function indexes [serum alanine amino-transferase （ALT）， aspartate transferase （AST）， and total bilirubin （TBil）] and tumor biomarkers [alpha fetoprotein （AFP）， carcinoembryonic antigen （CEA）， carbohydrate antigen 19-9 （CA19-9）， and des-gamma-carboxy prothrombin （DCP）] before treatment and after 3 months of treatment， as well as the occurrence of adverse drug reaction （ADR） during treatment， were compared between the two groups. In addition， overall response rate （ORR） stratified by PD-1 inhibitor type was analyzed. RESULTS After treatment， the ORR was significantly higher in the observation group than in the control group （P＜0.05）； although the disease control rate was higher in the observation group compared to the control group， the difference was not statistically significant （P＞0.05）. The median overall survival of patients in the observation group was 16.9 months [95% confidence interval （CI）： 14.2 to 19.1 months]， which was significantly longer than that in the control group （12.4 months， 95%CI： 10.1 to 15.3 months） （P＜0.05）. Subgroup analysis result indicated that therapeutic advantage was consistent across both sintilimab and tislelizumab subgroups， with no significant heterogeneity （P＞0.1， I 2＜0.001%）. Before treatment， there were no significant differences in liver function indexes or tumor marker levels between 2 groups （P＞0.05）. After treatment， both groups showed significant declines in these indicators compared with baseline （P＜0.05）， with greater reductions observed in the observation group （P＜0.05）. There were no statistically significant differences in overall incidence of ADR and grade ≥3 ADRs between the two groups （P＞0.05）. CONCLUSIONS For patients with unresectable HCC， the combination of donafenib， PD-1 inhibitors and vascular intervention therapy may achieve superior clinical outcomes without increasing the risk of treatment-related ADR.

Objective:To investigate the clinical and genetic characteristics of spinal muscular atrophy (SMA) patients with SMN1 gene compound heterozygous mutations. Methods:Three SMA-Ⅲ pedigrees treated in Henan Provincial People′s Hospital from October 2019 to July 2020 were selected. The clinical data of 3 SMA-Ⅲ probands were retrospectively analyzed. Multiplex ligation-dependent probe amplification (MLPA) technology was used to detect the copy number of the SMN gene in the probands and their parents. Polymerase chain reaction amplification combined with microfluidic capillary electrophoresis were used to detect point mutations in the SMN1 gene of the probands. Sanger sequencing was used to validate candidate variant sites. Results:The 3 probands are all male, aged 19, 17 and 12 years, respectively. The main clinical manifestations were symmetrical muscle weakness mainly in the proximal lower limbs, mild to moderate elevation of serum creatine kinase, and neurogenic injury as determined by electromyography or muscle pathology. The genetic testing results showed that all 3 probands had heterozygous deletion in exon 7 of the SMN1 gene, and carried heterozygous variations c.275G>A (p.Trp92 *), c.689C>T (p.Ser230Leu), and c.708dupT (p.Pro237Serfs *19), respectively. The exon deletion and point mutation were inherited separately from their parents. c. 275G>A (p.Trp92 *) and c.708dupT (p.Pro237Serfs *19) variations had not been reported before. Conclusions:The clinical manifestations of SMA-Ⅲ patients are symmetrical muscle weakness, mainly in the proximal extremities of both lower limbs, and electromyography or muscle biopsy suggesting neurogenic lesions. The compound heterozygous variation of point mutation and heterozygous deletion in the SMN1 gene can lead to SMA-Ⅲ. Suspected SMA patients with SMN1 gene heterozygous deletion should take point mutation testing.

Objective:To analyze the clinical manifestations and muscular magnetic resonance imaging (MRI) features of 12 families with facioscapulohumeral muscular dystrophy (FSHD).Methods:Retrospective analysis was conducted on 12 FSHD families diagnosed by genetic testing at the Department of Neurology of Henan Provincial People′s Hospital from January 2017 to June 2021. Clinical data and lower limb muscle MRI results of the probands and related members of the families were collected, and the degree of muscle fatty degeneration shown in the MRI was scored using the modified Mercuri score.Results:There were 21 patients in 12 families, with the age of onset ranged from 10 to 47 years (mean 19.5 years). The course of disease ranged from 1 to 47 years (mean 23.1 years). The onset sites included unilateral upper extremity in 8 cases, bilateral proximal upper extremities in 9 cases, bilateral proximal lower extremities in 2 cases, unilateral proximal lower extremity in 1 case, and simultaneous onset in all 4 limbs in 1 case. Sixteen patients had limb weakness and bilateral asymmetry, and 11/16 cases were more severe on the right side than the left side. Winged scapular and facial muscle weakness were observed in all patients. The creatine kinase range was 85-1 038 U/L (461 U/L on average) in 12/21 cases. There were 10/21 cases of myogenic lesion in electromyography. Myodystroph-like pathological changes were found in 11/21 cases. The fragment length of the 4q35 subtelomere polymorphism EcoRI/p13E-11 was less than 38 kb in 20/21 cases; 1 case was confirmed based on clinical symptoms and family history. Fat infiltration occurred in at least one muscle of lower limbs in 9/10 cases, in thigh muscle in 9/10 cases and in calf muscle in 6/10 cases. The average score of fat infiltration in thigh muscle group was higher than that in calf muscle group. The muscles with higher fat infiltration scores were the vastus intermedius, the long head of the biceps femoris, the vastus medialis, the vastus lateralis, the semitendinosus, the semimembranosus, the vastus lateralis in the thigh (with score ≥2.15), the tibialis anterior, and the medial head of the gastrocnemius in the calf (with score ≥1.11). Fat infiltration in the medial and posterior thigh muscles was more common than in the anterior thigh muscles. There was asymmetry of bilateral muscle fat in 9/10 cases. There were edematous changes in thigh muscles in 1 case and in calf muscles in 3 cases.Conclusions:The age of onset of FSHD patients is mostly ≤30 years. Bilateral asymmetric involvement is the characteristic manifestation of FSHD. The FSHD patients ' muscles most affected by the disease in the thigh are the quadriceps femoris, the long head of the biceps femoris, the vastus medialis, the vastus lateralis, the semitendinosus, the semimembranosus, and the vastus intermedius. In the calf, the muscles most affected are the anterior tibial muscle and the medial head of the gastrocnemius. The MRI pattern of muscle involvement of patients with FSHD is bilateral asymmetrical lesions, with the right side having more severe lesions. The fatization of thigh muscles is more significant than that of calf muscles, and the asymmetry of fatization between bilateral muscles is also present.
