Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

Objective: To understand the current status of short video addiction among vocational nursing students in higher vocational colleges (hereinafter referred to as "nursing students") and its related factors, so as to provide a reference for formulating online education programs in colleges. Methods: From March to May 2025, a stratified random sample of 2 223 nursing students from four vocational colleges in Henan Province was selected. Short Video Addiction Scale for College Students, Short form Egna Minnen av Barndoms Uppfostran for Chinese, Peer Rejection Scale, and University of California at Los Angels Loneliness Scale were used for investigation. Chi square test and multivariate Logistic regression analysis were used to explore the related factors of short video addiction among nursing students. Results: The detection rate of short video addiction of higher vocational nursing students was 26.95%, and the scores for avoidance, loss of control, inefficiency and withdrawal were (8.05±2.97) (10.24±3.09) (4.99±1.88) and (11.97±4.10), respectively. Multivariate Logistic regression analysis showed that sophomore year 2 ( OR=1.83, 95%CI =1.39-2.40), higher maternal education level (secondary school/vocational college: OR =1.34, 95% CI =1.06-1.68; college/undergraduate: OR =1.38, 95% CI =1.05-1.82), paternal overprotection ( OR=1.59, 95%CI =1.27-2.00), high peer rejection ( OR=1.40, 95%CI =1.19-1.66), and strong loneliness ( OR=1.57, 95%CI =1.07-2.28) were associated with a higher risk of short video addiction among nursing students (all P <0.05). Paternal affectionate and warm rearing style ( OR=0.82, 95%CI = 0.71- 0.95) was associated with a lower risk of short video addiction ( P <0.05). Conclusions The detection rate of short video addiction among nursing students is relatively high. Short video addiction is related to the nursing students grade, maternal education level, paternal overprotection and affectionate rearing style, peer rejection, and loneliness.

Objective:To investigate the effect of physical activity on mortality risk in patients with chronic obstructive pulmonary disease (COPD) in Sichuan Province.Methods:Based on baseline data from 2004 to 2008 from the China Kadoorie Biobank project site in Pengzhou City, Sichuan Province, a total of 8 501 COPD patients aged 30-79 years were enrolled and followed up for a long period to determine mortality outcomes. Quartiles were used to group physical activity levels. The Cox proportional hazards regression model was used to analyze the effect of physical activity level on mortality outcomes.Results:As of December 31, 2017, the cumulative follow-up of the participants totaled 85 600.58 person-years (mean follow-up duration: 10.07 years). During this period, a total of 2 000 deaths were recorded, yielding a cumulative mortality rate of 23.53%. Among these deaths, 665 were attributed to COPD, corresponding to a cumulative mortality rate of 7.82%; and 1 116 were attributed to cardiovascular and cerebrovascular disease (CVD), corresponding to a cumulative mortality rate of 13.13%. The Cox proportional hazards regression model analysis revealed that, after adjusting for confounding factors, total physical activity was associated with a reduced risk of mortality from COPD, CVD, and all causes in patients with COPD. Compared with the low-level group of total physical activity, the medium-high-level group had the lowest risk of COPD mortality, with an HR of 0.39 (95% CI: 0.30-0.49). The high-level group had the lowest risk of CVD death and all-cause death, with HRs of 0.46 (95% CI: 0.37-0.56) and 0.55 (95% CI: 0.48-0.64), respectively. The lowest risk of COPD death and CVD death was found in the medium-high level of work-based physical activity group, with HRs of 0.36 (95% CI: 0.28-0.46) and 0.43 (95% CI: 0.36-0.51), respectively; the risk of all-cause mortality was lowest in the medium-high and high-level groups, with HRs values of 0.53 (95% CI: 0.46-0.61) and 0.53 (95% CI: 0.45-0.61). The risk of COPD death was lowest in the high-level transportation physical activity group, with an HR of 0.66 (95% CI: 0.53-0.83), and the risk of CVD and all-cause death was lowest in the medium-high level group, with HRs of 0.63 (95% CI: 0.53-0.76) and 0.73 (95% CI: 0.64-0.84), respectively. The risk of COPD death and CVD death was the lowest in the high-level domestic physical activity group, with HRs of 0.66 (95% CI: 0.49-0.89) and 0.76 (95% CI: 0.61-0.95), respectively, and the risk of all-cause death was the lowest in the medium-high level group, with an HR of 0.82 (95% CI: 0.72-0.94). There is no statistical association between leisure physical activity and the risk of death from three types of diseases. Conclusions:Total physical activity, including work-based, transportation-based, and domestic physical activity, reduced the risk of COPD, CVD, and all-cause mortality in patients with COPD in Sichuan Province. The magnitude of mortality risk was influenced by the type and level of physical activity.

Phages, as obligate bacterial and archaeal parasites, constitute a virus group of paramount ecological significance due to their exceptional abundance and genetic diversity. These biological entities serve as critical regulators in Earth's ecosystems, driving biogeochemical cycles, energy fluxes, and ecosystem services across terrestrial and marine environments. Within soil microbiomes, phages function as microbial "dark matter," maintaining the soil-plant system balance through precise modulation of the microbial community structure and functional dynamics. Despite the growing research interests in soil phages in recent years, the proportion of such studies in environmental virology remains disproportionately low, which is primarily attributed to researchers' limited familiarity with the research methodologies for phage microecology, incomplete technical frameworks, and inherent challenges posed by soil environmental complexity. To address these challenges, this review synthesizes cutting-edge methodologies for soil phage investigation from four aspects: (1) tangential flow filtration (TFF)-based phage enrichment strategies; (2) integrated quantification approaches combining double-layer agar plating, epifluorescence microscopy, and flow cytometry; (3) multi-omics analytical pipelines leveraging metagenomics and viromics datasets; and (4) computational frameworks merging machine learning algorithms with eco-evolutionary theory for deciphering phage-host interaction networks. Through comparative analysis of methodological principles, technical merits, and application scopes, we establish a comprehensive workflow for soil phage research. Future research in this field should prioritize: (1) construction of soil phage resource libraries, (2) exploration of RNA phages based on transcriptomes, (3) functional characterization of unknown genes, and (4) deep integration and interaction validation of multi-omics data. This systematic methodological synthesis provides critical technical references for addressing fundamental challenges in characterizing soil phages regarding the community structure, functional potential, and interaction mechanisms with hosts.

From January 2020 to January 2022, 60 hospitalized patients with severe pneumonia complicated with gastrointestinal dysfunction (syndrome of lung heat and fu-organ excess) in the Intensive Care Department and Emergency Intensive Care Unit of Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine were selected as the observation subjects. They were divided into experimental group and control group according to random number table method, with 30 cases in each group. Patients in the control group were treated with conventional Western medicine, while patients in the experimental group received Xuanbai Chengqi Decoction combined with conventional Western medicine. Both groups were treated continuously for 7 days and followed up for 28 days. TCM syndrome scores were evaluated before and after treatment. Clinical Pulmonary Infection Score (CPIS) was used to assess pulmonary infection, Gastrointestinal Dysfunction Score (GIDS) was used to assess the degree of gastrointestinal dysfunction, and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was used to assess the prognosis. ELISA was used to detect levels of procalcitonin (PCT), IL-6, CRP, D-lactate (D-LA), short chain fatty acids (SCFA), and G protein coupled receptor 43 (GPR43). The fully automated blood analyzer (flow cytometry) was used to detect white blood cells (WBC) and the proportion of neutrophils (N%). Indirect bladder pressure measurement method was used to measure the intra-abdominal pressure of patients. During treatment, the adverse reactions or events were recorded. Patients were followed up for 28 days and the 28-day mortality rate was recorded.Results:The total effective rate was 73.33% (22/30) in the experimental group and 40.00% (12/30) in the control group, with statistical significance ( χ2=6.79, P<0.05). After treatment, TCM syndrome scores, CPIS, GIDS, and APACHEⅡ score in the experimental group were lower than those in the control group ( t values were 2.84，3.34，2.75，3.05，respectively， P<0.01), serum PCT [(0.35 ± 0.11) μg/L vs. (0.64 ± 0.10) μg/L, t=2.45], IL-6 [(19.33 ± 3.54) ng/L vs. (60.13 ± 15.01) ng/L, t=2.98], N% [(78.84 ± 2.09)% vs. (83.30±2.31)%, t=3.43], and CRP [(28.43 ± 6.38) mg/L vs. (54.48 ± 9.03) mg/L, t=4.02], intra-abdominal pressure [(9.11 ± 2.55) mmHg vs.(11.70 ± 3.02) mmHg, t=7.78] and D-LA [(0.11±0.05) mmol/L vs. (0.18±0.12) mmol/L, t=6.45] in the experimental group were lower than those in the control group ( P<0.05 or P<0.01). After treatment, serum SCFA [(48.18 ± 36.31) μmol/L vs. (35.10 ± 19.32)μmol/L, t=1.95] and GPR43 [(1 254.61 ± 437.40) ng/L vs. (990.15 ± 403.03) ng/L, t=2.13] in the experimental group were higher than those in the control group ( P<0.05). The 28-day mortality rates of the experimental group and the control group were 20.00% (6/30) and 46.67% (14/30) respectively, with statistical significance ( χ2=4.80, P<0.05). During the trial, there were no serious adverse reactions or adverse events in either group. Conclusion:Xuanbai Chengqi Decoction can effectively treat severe pneumonia complicated with gastrointestinal dysfunction. The mechanism may involve the up-regulation of SCFA/GPR43 axis.

Background and Aims:Totally implantable venous access ports(TIVAP)are widely used in patients requiring long-term intravenous therapy.Traditional butterfly needle puncture fixation methods have limitations,including low success rates,increased pain,and risk of needle-stick injury.This study aimed to design an adjustable puncture protection kit for butterfly needles and evaluate its clinical utility using a simulated device.Methods:A prospective randomized controlled trial was conducted with 70 patients implanted with upper arm ports in the Hematology Department of Xiangya Hospital,Central South University,from January to December 2024.The patients were divided into a study group and a control group,with 35 cases in each,using a randomized block design.The study group underwent puncture with the simulated adjustable protection kit,while the control group used the traditional finger fixation method.Outcomes compared included first-attempt success rate,vertical puncture rate,pain score,puncture time,and complication rate.Results:The baseline characteristics of the two groups were balanced.The study group had significantly higher first-attempt puncture success rate and vertical puncture rate than the control group(94.3%vs.77.1%;91.4%vs.57.1%,both P<0.05).In the experimental group compared with the control group,pain scores were lower(1.80±1.13 vs.2.94±1.33,P<0.05),and puncture time was shorter[(31.31±9.05)s vs.(41.80±23.97)s,P<0.05].There was no significant difference in the incidence of puncture-related complications between the two groups(2.9%vs.14.3%,P>0.05).Conclusion:The simulated adjustable butterfly needle puncture protection kit effectively improves puncture success,enhances efficiency,reduces patient pain,and demonstrates good clinical safety.This innovative design provides a promising solution for reducing needle-stick injury risks and optimizing port puncture procedures,although larger,multicenter,and long-term studies are warranted.

Objective:To explore the dynamic effects of venous sinus stenting (VSS) implantation on the optic nerve structure and visual function in patients with idiopathic intracranial hypertension (IIH).Methods:Patients with IIH combined with venous sinus stenosis and optic disc edema who were admitted to the Beijing Tiantan Hospital and received VSS treatment from January 2019 to September 2023 were prospectively included. Before the operation, the general data of the patients were collected and lumbar puncture examination was performed to measure the cerebrospinal fluid pressure. Ophthalmic multimodal imaging examinations such as binocular best corrected visual acuity (BCVA), optic disc stereoscopic photography, visual field, and optical coherence tomography (OCT) were performed respectively before the operation, 3 months and 6 months after the operation. The BCVA of both eyes, the Frisén grade (FPG) of optic disc edema, the mean defect (MD) value of the visual field, the thickness of the retinal nerve fiber layer (RNFL) around the optic disc and the thickness of the optic ganglion cell complex (GCC) were collected respectively. The eye with poor preoperative visual field MD value was defined as the study eye, and the other eye was the contralateral eye. The Friedman rank sum test was used to statistically analyze the differences of various indicators before the operation, 3 months after the operation and 6 months after the operation. Further, the Wilcoxon signed rank test was used to pairwise compare the results at the three time points.Results:A total of 72 patients with IIH who met the criteria were included, among whom 61 were female (84.7%), and the baseline optic disc edema Frisén grade was 3(2-4). The FPG, BCVA, MD values and RNFL thickness of the study eye and the contralateral eye at 3 and 6 months after the operation were significantly improved compared with those before the operation (all P<0.017). At 6 months after the operation, the FPG, BCVA, MD value, RNFL thickness of the study eye and the FPG and RNFL thickness of the contralateral eye were further improved compared with those at 3 months, and the differences were statistically significant (all P<0.017). During the treatment and follow-up period, no serious adverse reactions occurred in all patients. Conclusions:VSS can effectively improve papillary edema and visual function impairment in patients with IIH combined with venous sinus stenosis. Ophthalmic multimodal imaging examination provides an objective basis for preoperative assessment of optic nerve structure and visual function, postoperative efficacy monitoring and visual function recovery, etc. In the diagnosis and treatment process of IIH, the collaborative cooperation between the neurology department and the ophthalmology department is very important.
