Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals", it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure, qi and liquid imbalance, and kidney collaterals impairment, and it is proposed that the treatment principle is to nourish the sweat pore, regulate qi and fluid, and supplement the kidney and unblock the collaterals. In clinic, guided by sequential therapy and according to the different disease mechanism characteristics of the four stages, including early stage of the disease, hormone induction stage, hormone reduction stage, hormone maintenance stage, the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency, modified Zhenwu Decoction (真武汤) was applied to warm yang and drain water; for hormone induction stage with yin deficiency resulting in effulgent fire, modified Zhibai Dihuang Pill (知柏地黄丸) plus Erzhi Pill (二至丸) was used to enrich yin and reduce fire; for hormone reduction stage with qi and yin deficiency, modified Shenqi Dihuang Decoction (参芪地黄汤) was used to boost qi and nourish yin; for hormone maintenance stage, modified Shenqi Pill (肾气丸) was used to supplement yin and yang. Meanwhile, the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals, so as to providing ideas for clinical treatment.

BACKGROUND:
Senescent human skin primary fibroblast (FB) models have been established for studying aging-related, proliferative, and inflammatory skin diseases. The aim of this study was to compare the transcriptome characteristics of human primary dermal FBs from children and the elderly with four senescence models.
METHODS:
Human skin primary FBs were obtained from healthy children (FB-C) and elderly donors (FB-E). Senescence models were generated by ultraviolet B irradiation (FB-UVB), D-galactose stimulation (FB-D-gal), atazanavir treatment (FB-ATV), and replication exhaustion induction (FB-P30). Flow cytometry, immunofluorescence staining, real-time quantitative polymerase chain reaction, co-culturing with immune cells, and bulk RNA sequencing were used for systematic comparisons of the models.
RESULTS:
In comparison with FB-C, FB-E showed elevated expression of senescence-related genes related to the skin barrier and extracellular matrix, proinflammatory factors, chemokines, oxidative stress, and complement factors. In comparison with FB-E, FB-UVB and FB-ATV showed higher levels of senescence and expression of the genes related to the senescence-associated secretory phenotype (SASP), and their shaped immune microenvironment highly facilitated the activation of downstream immune cells, including T cells, macrophages, and natural killer cells. FB-P30 was most similar to FB-E in terms of general transcriptome features, such as FB migration and proliferation, and aging-related characteristics. FB-D-gal showed the lowest expression levels of senescence-related genes. In comparisons with the single-cell RNA sequencing results, FB-E showed almost complete simulation of the transcriptional spectrum of FBs in elderly patients with atopic dermatitis, followed by FB-P30 and FB-UVB. FB-E and FB-P30 showed higher similarity with the FBs in keloids.
CONCLUSIONS
Each senescent FB model exhibited different characteristics. In addition to showing upregulated expression of natural senescence features, FB-UVB and FB-ATV showed high expression levels of senescence-related genes, including those involved in the SASP, and FB-P30 showed the greatest similarity with FB-E. However, D-galactose-stimulated FBs did not clearly present aging characteristics.

Objective To measure the air-absorbed dose rate of gamma radiation in public areas for the situation of the local radiation environment. Methods Using a large-volume γ spectrometer system with a NaI(Tl) detector mounted on a UAV, we conducted large-scale airborne radiation monitoring in public areas in southwestern China, to measure the air-absorbed dose rate at a height of 1 m from the earth’s surface. Results The airborne radiation monitoring data were used to analyze the local radiation environment. The mean air-absorbed dose rate at a height of 1 m was 43.6 ± 12.9 nGy/h. Seven abnormal radiation points were detected, and two of them were located where construction was ongoing. At one of the abnormal radiation points, FH40G meter measurements showed that the air-absorbed dose rate at a height of 1 m was up to 22.0 μGy/h. Field soil samples were collected for HPGe γ spectrometer analysis: the 232Th radionuclide activity concentration was 96.0 kBq/kg, and the 226Ra radionuclide activity concentration was 9.9 kBq/kg. Conclusion Using the UAV-mounted large-volume γ spectrometer system with NaI(Tl) detectors for large-scale airborne monitoring is a fast and effective method for dragnet monitoring of the level of radiation in public areas.

OBJECTIVE To investigate the mechanism of Yifei xuanfei jiangzhuo formula (YFXF) against vascular dementia (VD). METHODS The differentially expressed genes of YFXF (YDEGs) were obtained by network pharmacology. High-risk genes were screened from YDEGs by using the nomogram model. The optimal machine learning models in generalized linear, support vector machine, extreme gradient boosting and random forest models were screened based on high-risk genes. VD model rats were established by bilateral common carotid artery occlusion, and were randomly divided into model group and YFXF group (12.18 g/kg, by the total amount of crude drugs), and sham operation group was established additionally, with 6 rats in each group. The effects of YFXF on behavior (using escape latency and times of crossing platform as indexes), histopathologic changes of cerebral cortex, and the expression of proteins related to the secreted phosphoprotein 1 (SPP1)/phosphoinositide 3-kinase (PI3K)/protein kinase B (aka Akt) signaling pathway and the mRNA expression of SPP1 in cerebral cortex of VD rats were evaluated. RESULTS A total of 6 YDEGs were obtained, among which SPP1, CCL2, HMOX1 and HSPB1 may be high-risk genes of VD. The generalized linear model based on high-risk genes had the highest prediction accuracy (area under the curve of 0.954). Compared with the model group, YFXF could significantly shorten the escape latency of VD rats, significantly increase the times of crossing platform (P<0.05); improve the pathological damage of cerebral cortex, such as neuronal shrinkage and neuronal necrosis; significantly reduce the expressions of SPP1 protein and mRNA (P<0.05), while significantly increase the phosphorylation levels of PI3K and Akt (P<0.05). CONCLUSIONS VD high-risk genes SPP1, CCL2, HMOX1 and HSPB1 may be the important targets of YFXF. YFXF may play an anti-VD role by down-regulating the protein and mRNA expressions of SPP1 and activating PI3K/Akt signaling pathway.

To compare and analyze the "same disease, same price" policy in the regionsimplementing diagnosis related group(DRG) payment reform, and to provide recommendations for further policy optimization and extension. DRG policies published on official website of healthcare security bureaus from all provinces and 190 cities between 1 January 2019 to 31 May 2024 were collected. Microsoft excel was applied to collect the information, and the comparative analysis method was used to summarize and analyze the DRG polices from three dimensions: region, healthcare facility, and disease groups coverage. The regions where the "same disease, same price" policy in DRG payment was implemented were limited and unevenly distributed. The policy has been implemented in 76 cities across 16 provinces, 2 municipalities, and 3 autonomous regions, accounting for 40% of the cities implementing DRG payment. The pilot cities were mainly concentrated in eastern China. Coverage of healthcare facilities varied across regions. This policy covered all levels of healthcare institutions in most of the pilot cities, while it was primarily implemented in secondary and tertiary hospitals in some regions. The selection criteria for primary disease groups were generally consistent: the common diseases with mature diagnostic, treatment techniques and stable medical costs. However, the number, relative weight, and distribution of primary disease groups varied across regions, with the number ranging from 3 to 117 and relative weight ranging from 0.16 to 1.57. The primary diseases were mainly concentrated in internal diseases, with asthma and hypertension being the most common disease groups. It is recommended to expand the scope of region coverage, determine the scope of hospital coverage according to local capacities, expand the scope of disease groups by stages, and evaluate the effect of policy implementation.

Objective:To observe the effects of acupuncture and moxibustion on ubiquitin-like containing PHD and RING finger domains 1(UHRF1)and DNA methyltransferase 1(DNMT1)in ectopic endometrium of rats with endometriosis(EMS). Methods:Forty Sprague-Dawley rats were randomly divided into a sham operation group with 10 rats and a model-building group with 30 rats according to body mass.EMS rat models were established in the model-building group and then were divided into a model group,an acupuncture and moxibustion group,and a progesterone group,with 10 rats in each group.All rats were fixed by a fixator.The sham operation group and the model group were given normal saline by gavage.The acupuncture and moxibustion group received acupuncture at Xuehai(SP10)and Sanyinjiao(SP6),moxibustion at Guanyuan(CV4),and gavage of normal saline.The progesterone group was given the mixed liquid made of dydrogesterone and normal saline by gavage.After 28 d of treatments,the three diameters(length,width,and height)of EMS rats'ectopic cysts were measured,the cyst volumes were calculated,the volumes before intervention were subtracted,and the difference values were used to evaluate the growth of ectopic cysts.UHRF1 and DNMT1 mRNA and protein levels in normal endometrium,eutopic endometrium,and ectopic endometrium were detected by real-time polymerase chain reaction and immunohistochemistry. Results:There was no significant difference in the ectopic cyst volume difference between the acupuncture and moxibustion group and the progesterone group(P>0.05),but they were smaller than that of the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the ectopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of DNMT1 mRNA and UHRF1 protein in the eutopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of UHRF1 mRNA and protein and the level of DNMT1 protein in the ectopic endometrium of the acupuncture and moxibustion group were higher than those in the model group(P<0.05),and the level of UHRF1 mRNA was higher than that in the progesterone group(P<0.05).The level of DNMT1 mRNA in the eutopic endometrium of the acupuncture and moxibustion group was higher than that in the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the acupuncture and moxibustion group were insignificantly different from those in the normal endometrium(P>0.05). Conclusion:Acupuncture and moxibustion may up-regulate the levels of UHRF1 mRNA and UHRF1 and DNMT1 proteins in the ectopic endometrium to the normal level so as to reduce the volume of ectopic cysts and cure EMS in rats.

Objective:
Autism spectrum disorder (ASD) is a neurodevelopmental disorder with onset in infancy. Early intervention is critical to improve the prognosis for these children. E-health interventions have tremendous potential. This review aimed to determine the status and effectiveness of family interventions for parents of children aged 0–6 years with ASD in the context of e-health.
Methods:
The review methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. PubMed, Web of Science, and China National Knowledge Infrastructure were searched from inception to June 2022. The searches were limited to children with ASD of the age range between 0 and 6 years. We collated the available information and used descriptive statistics to analyze the synthesized data.
Results:
Our initial search identified 3,672 articles, of which 30 studies met the inclusion criteria. The 30 articles selected were released between 2012 and 2022. All articles are in English. Most articles reviewed were from high-income countries (27/30, 90.0%), especially from the United States (16/30, 53.3%). Four major themes emerged from the 30 studies that matched the inclusion criteria, as follows: 1) type of e-health interventions, 2) duration of interventions, 3) clinical aspects of e-health interventions, and 4) evidence for intervention effectiveness, looking into the positive, negative, and mixed findings of previous studies.
Conclusion
These findings suggest that a wide variety of e-health interventions may actually help support both children with ASD aged 0–6 years and their parents.

Objective:To evaluate the efficacy and safety of endoscopic biliary drainage for biliary fistula.Methods:Data of consecutive 409 biliary fistula patients who were treated and diagnosed at the First Medical Center of Chinese PLA General Hospital from November 2002 to November 2022 were reviewed, and 53 patients who received endoscopic retrograde cholangiopancreatography (ERCP) drainage were finally included. General information, procedural conditions, clinical outcomes and adverse events were analyzed. The patients were categorized into two groups: the endoscopic retrograde biliary drainage (ERBD) group ( n=46) and the endoscopic nasobiliary drainage (ENBD) group ( n=7). Procedural characteristics, operation outcomes, and operation time were compared between the two groups. Results:There were 36 males and 17 females, with the age of 52.2±12.7 years, among whom 58.5% (31/53) were secondary to cholecystectomy. Clinical success was achieved in 83.0% (44/53) patients, with the operation time of 27.0 (13.5, 33.5) minutes and the treatment session of 1 (1, 2). The time to resolution was 89 (47, 161) days. The success rate of ERCP for low-grade biliary fistula was higher compared with that of high-grade biliary fistula [96.4% (27/28) VS 68.0% (17/25), χ2=7.57, P=0.006]. Bridging drainage achieved higher success rate compared with that of non-bridging drainage [91.7% (33/36) VS 64.7% (11/17), χ2=5.95, P=0.015], while different diameters of stents (≥10 Fr VS <10 Fr) achieved similar success rate [81.8% (27/33) VS 84.6% (11/13), χ2=0.05, P=0.822]. Adverse events occurred in 10 patients (18.9%), including 6 pancreatitis, 2 bleeding, 1 cholangitis and 1 death. Except for 1 death, 9 other adverse events were mild and managed with conservative treatment without interventions. There was no significant difference in clinical success rate [6/7 VS 82.6% (38/46), χ2=0.04, P=0.838] or the median operation time [28.0 min VS 23.0 min, Z=0.38, P=0.774] between ENBD group and ERBD group. Conclusion:Endoscopic biliary drainage is safe and effective for biliary fistula. ENBD and ERBD have comparable clinical efficacy. ERCP for low-grade biliary fistula may achieve a higher success rate, and bridging drainage may facilitate fistula resolution.

A series of chemotherapeutic drugs that induce DNA damage, such as cisplatin (DDP), are standard clinical treatments for ovarian cancer, testicular cancer, and other diseases that lack effective targeted drug therapy. Drug resistance is one of the main factors limiting their application. Sensitizers can overcome the drug resistance of tumor cells, thereby enhancing the antitumor activity of chemotherapeutic drugs. In this study, we aimed to identify marketable drugs that could be potential chemotherapy sensitizers and explore the underlying mechanisms. We found that the alcohol withdrawal drug disulfiram (DSF) could significantly enhance the antitumor activity of DDP. JC-1 staining, propidium iodide (PI) staining, and western blotting confirmed that the combination of DSF and DDP could enhance the apoptosis of tumor cells. Subsequent RNA sequencing combined with Gene Set Enrichment Analysis (GSEA) pathway enrichment analysis and cell biology studies such as immunofluorescence suggested an underlying mechanism: DSF makes cells more vulnerable to DNA damage by inhibiting the Fanconi anemia (FA) repair pathway, exerting a sensitizing effect to DNA damaging agents including platinum chemotherapy drugs. Thus, our study illustrated the potential mechanism of action of DSF in enhancing the antitumor effect of DDP. This might provide an effective and safe solution for combating DDP resistance in clinical treatment.
