This paper summarizes clinical insights on treating the syndrome of coexisting dryness and dampness in Sjögren's syndrome （SS） based on the "three methods for liver diseases". It is proposed that the core pathogenesis of this subtype lies in the liver's failure to regulate and disperse， leading to fluid retention and transformation into dryness； disharmony between wood （liver） and earth （spleen）， resulting in internal generation of dryness and dampness； and liver impairment affecting the kidney， eventually causing extreme dryness to transform into dampness. This syndrome is thus characterized by disharmony between the liver and spleen， as well as dysfunction between ti （character， 体） and yong （function， 用）. Drawing from the Guide to Clinical Case （《临证指南医案》）， the "three methods for liver diseases" are applied as follows，i.e. using pungent and dispersing herbs to regulate the liver and resolve qi stagnation； using sweet and gentle herbs to soothe the liver and address the root of concurrent dryness and dampness； and using sour and purgative herbs to soften the liver and restore fluid balance. The coordinated use of these three methods， treating both ti and yong， facilitates the separation of dryness and dampness， providing a novel approach to syndrome differentiation and treatment for this subtype of SS.

Objective To investigate the current status of pelvic floor muscle training(PFMT)adherence for preventing low anterior resection syndrome(LARS)in rectal cancer patients with prophylactic ostomy and analyze its influencing factors.Methods A total of 247 patients who underwent preventive stoma reversal surgery after sphincter-preserving rectal cancer resection between January 2024 and February 2025 at 22 tertiary hospitals in the Beijing-Tianjin-Hebei region were recruited in this study.Their clinical data were collected through a general information questionnaire,a LARS Knowledge-Attitude-Practice and Needs questionnaire,a PFMT Self-Efficacy Scale,and a PFMT Adherence Questionnaire.Univariate analysis,correlation analysis,LASSO regression,and random forest importance ranking were applied to screen the variables,and multiple linear regression analysis was conducted to analyze the significant variables.Results The overall PFMT adherence score was 14.52±4.18 among the 247 patients.The random forest algorithm identified 7 key predictors when the minimum error was achieved at a λ value of 2.293.The top 7 variables in importance ranking were PFMT self-efficacy,total knowledge-attitude-practice(KAP)score,education level,primary caregiver,tumor location,stoma reversal time,and chemoradiotherapy.Multiple linear regression analysis revealed that PFMT self-efficacy(P<0.001,β=0.007,95%CI:0.004～0.009),total KAP score(P<0.001,β=0.052,95%CI:0.035～0.070),stoma reversal time(P<0.030,β=-0.539,95%CI:-1.025～-0.053),and chemoradiotherapy(P<0.045,β=-0.451,95%CI:0.010～0.892)were significant related factors of PFMT adherence(P<0.05).Conclusion PFMT adherence for LARS prevention is at a moderate level in rectal cancer patients with prophylactic ostomy.Key factors such as PFMT self-efficacy,total KAP score,stoma reversal time,and chemoradiotherapy are significantly correlated with PFMT adherence.

Objective To evaluate the clinical efficacy of platelet-rich plasma(PRP)in treat-ment of diabetic foot ulcers(DFU)using a meta-analysis approach.Methods Relevant literature on PRP for treatment of DFU was collected by searching databases including PubMed,Cochrane Library,Embase,Web of Science,NEJM,CNKI,Wanfang Data,VIP Database,and China Biology Medicine disc.Relevant literature on PRP for treatment of DFU was collected.The literature was read,and effect sizes were extracted.The extracted data were then subjected to a meta-analysis using RevMan 5.3 software.Results A total of 6 studies were included in this meta-analysis,involving 440 pa-tients.Among them,there were 208 patients in experimental group(PRP combined with conventional treatment)and 232 patients in control group(conventional treatment,blank control,or placebo treat-ment).The ulcer healing efficacy rate in the experimental group was higher than that in the control group(OR=1.29,95％CI,1.19 to 1.40,P＜0.05).The incidence of adverse reactions in the experimental group was lower than that in the control group(OR=0.33,95％CI,0.12 to 0.93,P=0.94).The healing time(MD=-14.37,95％CI,-23.12 to-5.62,P=0.001),thickness of granulation tissue on the ulcer surface(MD=1.60,95％CI,1.31-1.88,P＜0.000 01),coverage rate of granulation tissue on ulcer surface(MD=6.03,95％CI,3.79 to 8.26,P＜0.05),and level of vascular endothelial growth factor on the ulcer surface(MD=7.62,95％CI,1.57 to 13.67,P=0.01)in the experimental group were all superior to those in the control group.Con-clusion PRP treatment for DFU has the advantages of improving the ulcer healing efficacy rate,shortening the ulcer healing time,promoting the growth of granulation tissue on the ulcer surface,and reducing the incidence of adverse reactions.

Objectives:This study aims to investigate optimal surgical management strategies for pediatric patients diagnosed with volume-overloaded mitral regurgitation. Methods:A comprehensive retrospective analysis was conducted on a cohort of 110 pediatric patients who underwent primary mitral valve repair for volume-overloaded mitral regurgitation at Fuwai Hospital between April 2020 and March 2022.The cohort,with an average age of(14.5±15.1)months and 38.2%males,was divided into standardized group for patients receiving 3-step standardized mitral valvuloplasty(n=69)and annuloplasty group for patients undergoing annuloplasty only(n=41).After propensity score matching,a total of 38 pairs of patients were included,comparing the primary endpoint(functional mitral failure and postoperative heart failure)between the two groups. Results:Over a median follow-up of 26.3(19.8,32.9)months,and with a median echocardiographic follow-up of 11.9(7.5,14.8)months,no death was recorded.Among the cases,one patient(0.8%)necessitated unplanned reoperation;and seven patients(6.4%)experienced a recurrence of moderate-severe mitral regurgitation as observed through echocardiography beyond 6 months post-surgery.Additionally,nine patients developed heart failure at one month post-discharge.Above events were similar between the two groups.Following propensity score matching,patients in the standardized group demonstrated significantly longer cardiopulmonary bypass and aortic cross-clamp times compared to the annuloplasty group(both P＜0.05),other outcomes were similar between the two groups.Subgroup analysis based on age indicated that infants(＜1 year old)in the standardized group exhibited a significantly lower incidence of major endpoint events compared to the annuloplasty group.Additionally,postoperative echocardiography in annuloplasty group indicated that Z score of left ventricular end diastolic diameter was still greater than 2 during the latest follow-up. Conclusions:Patients with volume-overloaded mitral regurgitation in the standardized group exhibited comparable perioperative recovery and postoperative outcomes as in the annuloplasty group.For pediatric patients suffering from volume-overloaded mitral regurgitation,particularly those under one year of age,the standardized surgical approach exhibited reduced rates of heart failure and major endpoint events,and this strategy is more suitable for this patient group.

Background The mental health status of prison officers is crucial to the efficiency, security, and stability of a prison, and it is essential to pay attention to the factors that influence their mental health. Objective To understand the mental health status of prison officers, and analyze how nature exposure affects their mental health problems and a potential mediating role of mental fatigue. Methods A cross-sectional survey was carried out from May to June 2022 among 1392 prison officers from eight prisons in a province, and a total of 1284 valid questionnaires were recovered. The Nature Exposure Scale, Mental Fatigue Scale, and Depression-Anxiety-Stress Scale were used to assess nature exposure, mental fatigue, and mental health indicators among prison officers, and to explore the effect of nature exposure on mental health problems and a potential mediating role of mental fatigue. Results The recruited prison officers showed high levels of depression, anxiety, and stress. The prevalence rates of depression, anxiety, and stress were 59.11% (759/1284), 60.67% (779/1284),and 43.93% (564/1284), respectively. The results of correlation analysis revealed that nature exposure was negatively related with mental fatigue and mental health indicators (depression, anxiety, and stress) (r_s=−0.242, −0.308, −0.235, −0.254, P<0.01), while mental fatigue was positively correlated with mental health indicators (depression, anxiety, and stress) (r_s=0.546, 0.533, 0.536, P<0.01). The PROCESS macro results showed that the level of nature exposure among prison officers negatively associated with depression, anxiety, and stress (β=−0.180, −0.104, −0.123), and mental fatigue played a mediating role, with indirect effects of −0.200, −0.192, and −0.199, respectively. Conclusion The levels of depression, anxiety, and stress of prison officers are higher than those of other occupations. Nature exposure negatively associates with depression, anxiety, and stress, that is, it may directly alleviate the mental health problems of prison officers; and it may also alleviate mental health problems by relieving mental fatigue.

Two pediatric heart failure patients were treated with pulmonary artery banding(PAB)at Fuwai Hospital,from December 2021 to January 2022.In the first case,an 8-month-old patient presented with left ventricular non-compaction cardiomyopathy(LVNC),left ventricular systolic dysfunction,ventricular septal defect,and atrial septal defect.The second case was a 4-month-old patient with LVNC,left ventricular systolic dysfunction,and coarctation of the aorta.After PAB,the left ventricular function and shape of both patients were significantly improved,without serious surgery-related complications.In these individual cases of pediatric heart failure,pulmonary artery banding exhibited a more satisfactory efficacy and safety compared to pharmacological treatment,especially for those with unsatisfactory medication results.Future clinical data are needed to promote the rational and broader application of this therapeutic option for indicated patients.

Objective:To investigate the ultrasonographic features and genetic etiology of complex talipes equinovarus (TE) in fetuses.Methods:This retrospective study enrolled 95 cases of complex TE (TE complicated by other abnormalities) who were diagnosed by prenatal ultrasound in the Third Affiliated Hospital of Zhengzhou University from March 2018 to December 2022. Chromosome karyotype analysis and/or chromosomal microarray analysis (CMA) [or copy number variation-sequencing (CNV-seq)] were performed on all cases for prenatal genetic diagnosis and those with normal results were further tested by whole exome sequencing (WES). Prenatal ultrasonographic and genetic features of complex TE in fetuses were summarized. Complicated abnormalities in the fetuses were classified into nine categories according to the involved system or site and based on each category these subjects were divided into with or without the corresponding complicated abnormalities groups. Besides, these cases were also divided into single-system and multi-system abnormality groups based on the number of involved systems or sites of complicated abnormalities. The detection rates of WES abnormality (pathogenic or likely pathogenic variants) and the overall detection rate of genetic abnormality [karyotype abnormality detected by chromosome karyotype analysis, pathogenic or likely pathogenic copy number variations (CNVs) detected by CMA (or CNV-seq), and pathogenic or likely pathogenic variation detected by WES] were compared between different groups using Chi-square test or Fisher's exact test. Results:Abnormal chromosome karyotypes were identified in 10 (24.4%) of 41 cases receiving chromosome karyotype analysis, pathogenic and likely pathogenic CNVs were found in seven (7.6%) of 92 cases by CMA (or CNV-seq). WES was performed on 37 cases with negative results of chromosomal karyotype analysis and CMA (or CNV-seq) and the detection rate of pathogenic and likely pathogenic variants was 43.2% (16/37). The detection rate of WES abnormality was higher in the fetuses with musculoskeletal abnormalities than in those without the abnormalities [71.4% (15/21) vs. 1/16, Fisher's exact test, P<0.001], while in those with other postural abnormalities was higher than that in the group without other postural abnormalities [12/16 vs. 19.0% (4/21), Fisher's exact test, P=0.001]. The genetic causes of complex TE were identified in 34.7% (33/95) of the fetuses by the sequential genetic diagnosis using chromosome karyotype analysis, CMA (or CNV-seq), and WES. The overall detection rate of genetic abnormality was higher in the group with multi-system abnormality than in the group with single-system abnormality [48.9% (22/45) vs. 22.0% (11/50), χ2=7.55, P=0.006], in the group with musculoskeletal system abnormalities and without [46.8% (22/47) vs. 22.9% (11/48), χ2=5.98, P=0.014], and in the group with other postural abnormality and without [47.2% (17/36) vs. 27.1% (16/59), χ2=3.99, P=0.046]. Nine cases that were considered isolated TE on initial ultrasound were corrected to a complex diagnosis on subsequent ultrasound examinations. Of all the involved system or site, the neurologic abnormalities were the most diverse (13 kinds) and had a diversity of ultrasound presentations. Conclusions:Genetic diagnosis should be performed when prenatal ultrasound suggests fetal complex TE. WES is conducive to improving the prenatal detection rate of monogenic diseases, especially in fetuses complicated by musculoskeletal abnormalities. Isolated TE fetuses require serial ultrasound examinations to correct the diagnosis in time and genetic testing should be performed if necessary. Additional attention should be paid to the TE fetus for comorbid neurologic abnormalities at the time of ultrasonography to rule out TE as an intrauterine harbinger of neuromuscular disease.

Objective:To investigate the effect of N-acetylserotonin (NAS) on the retinal microglia polarization in retinal ischemia-reperfusion injury (RIRI) rats and explore its mechanism via nucleotide-bound oligomeric domain 1 (NOD1)/receptor interacting protein 2 (Rip2) pathway.Methods:Healthy male Sprague Dawley rats were randomly divided into Sham ( n=21), RIRI ( n=21) and NAS (injected intraperitoneally 30 min before and after modeling with NAS, 10 mg/kg, n=18) groups, using random number table. And the right eye was used experimental eye. The RIRI model of rats in RIRI group and NAS group was established by anterior chamber high intraocular pressure method. Rats in NAS group were intraperitoneally injected with 10 mg/kg NAS before and 30 min after modeling, respectively. The retinal morphology and the number of retinal ganglion cell (RGC) in each group were detected by hematoxylin-eosin staining and immunohistochemical staining. The effect of NAS on polarization of retinal microglia was detected by immunofluorescence staining. Transcriptome sequencing technology was used to screen out the differentially expressed genes between Sham and RIRI groups. Western blot and real-time quantitative polymerase chain reaction (RT-PCR) were used to examine the differentially expressed genes. Immunohistochemical staining, Western blot and RT-PCR were used to investigate the effect of NAS on the expression of NOD1 and Rip2 protein and mRNA in retinal tissue and microglia of rats. General linear regression analysis was performed to determine the correlation between the number difference of NOD1 + cells and the number difference of M1 and M2 microglia in retinal tissues of rats in NAS group and RIRI group. Results:A large number of RGC were observed in the retina of rats in Sham group. 24 h after modeling, compared with Sham group, the inner retinal thickness of rats in RIRI group was significantly increased and the number of RGC was significantly decreased. The thickness of inner retina in NAS group was significantly thinner and the number of RGC was significantly increased. Compared with Sham group, the number of retinal microglia of M1 and M2 in RIRI group was significantly increased. Compared with RIRI group, the number of M1 microglia decreased significantly and the number of M2 microglia increased significantly in NAS group. There was statistical significance in the number of M1 and M2 microglia in the retina of the three groups ( P<0.05). Transcriptome sequencing results showed that retinal NOD1 and Rip2 were important differential genes 24 h after modeling. The mRNA and protein relative expressions of NOD1 and Rip2 in retina of RIRI group were significantly higher than those of Sham group, with statistical significance ( P<0.05). The number of NOD1 + and Rip2 + cells and the relative expression of mRNA and protein in retinal microglia in RIRI group were significantly higher than those in Sham group, and NAS group was also significantly higher than that in Sham group, but lower than that in RIRI group, with statistical significance ( P<0.05). The number of Iba-1 +/NOD1 + and Iba-1 +/Rip2 + cells in retinal microglia in RIRI group was significantly increased compared with that in Sham group, and the number of Iba-1 +/Rip2 + cells in NAS group was significantly decreased compared with that in RIRI group, but still significantly higher than that in Sham group, with statistical significance ( P<0.05). Correlation analysis results showed that the difference of retinal NOD1 + and Rip2 + cells in NAS group and RIRI group was positively correlated with that of M1 microglia ( r=0.851, 0.895), and negatively correlated with that of M2 microglia ( r=-0.797, -0.819). The differences were statistically significant ( P<0.05). Conclusion:NAS can regulate the microglial polarization from M1 to M2 phenotype, the mechanism is correlated with the NOD1/Rip2 pathway.
