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 explore the management of blood donors tested reactive to HCV in blood screening based on confirmation of HCV infection. Methods: Multiple HCV antibody assays, repeating HCV RNA testing, follow-up of blood donors and retesting of archive samples were performed to confirm HCV infection, identify infection status, and exclude false positives in blood donors reactive to HCV in blood screening. Results: From 2011 to 2024, the unqualified rate of HCV detection in blood screening was 2.45‰(2 751/1 122 026). Among these, anti-HCV+-&NAT-accounted for 1.85‰, followed by anti-HCV++ at 0.60‰. The proportion of anti-HCV+-&NAT-and HCV RNA yields was extremely low (0.007‰). The positive rate of anti-HCV+-&NAT-samples tested by electrochemiluminescence method (ELCIA) was approximately 7.5%, differing among reagents (P<0.05). The follow-up of anti-HCV+-&NAT-donors showed that 96.2% (202/210) were false positives, but 51.4% of donors remained anti-HCV+-&NAT-during follow-up. Among them, 8 donors (3.8%) could not be ruled out from HCV infection due to positive retesting by ELCIA. Of the anti-HCV+-&NAT-donors who were reactive at the first follow-up, 86.8% remained anti-HCV+-&NAT-at the second follow-up. The sampling confirmation data showed that all of 260 anti-HCV++ donors were confirmed as anti-HCV positive, and the proportion of false positives or missed detections by NAT was very low. Two occult HBV infections (OBIs) and one HBsAg carrier were identified among the 3 anti-HCV +-&NAT+ donors, and no HCV infection was confirmed in 5 anti-HCV--&HCV RNA + donors. Conclusion: The prevalence of HCV among blood donors in Dalian was about 0.06%, with extremely low proportion of window-period infection and slightly higher proportion of resolved infections than that of current infections. The majority of anti-HCV+-&NAT-were false positive. Blood donors confirmed as false positive should be qualified in blood screening 3 months later before next donation. In order to reduce the false positive results, it was advisable to avoid the same type of supplementary reagents as the initial reagents when performing confirmation.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

OBJECTIVE To analyze the clinical distribution characteristics and drug resistance of Enterobacter cloa-cae in Gansu Province from 2019 to 2023,providing reference for the prevention and control of E.cloacae infec-tions in this region.METHODS Data on the distribution and drug resistance of E.cloacae from hospitals in mem-ber units of the Gansu Antimicrobial Surveillance Network between 2019 and 2023 were collected.In vitro drug susceptibility testing was performed by the Kirby-Bauer disk diffusion(K-B)method,minimum inhibitory con-centration method,and fully automated instrumentation,followed by analysis of the susceptibility results.RESULTS From 2019 to 2023,a total of 402 490 bacterial strains were isolated and cultured in Gansu Province,including 17 417 strains of E.cloacae,with a detection rate of 4.33％.The bacteria were primarily iso-lated from sputum specimens(62.81％),followed by urine(7.37％)and wound pus specimens(6.07％).The de-partmental distribution was dominated by internal medicine(44.96％)and surgery(28.50％).The highest detec-tion rate was observed in the adult group(15-65 years,45.79％).E.cloacae exhibited varying degrees of resist-ance to over 20 antibacterial drugs,but the overall drug resistance rate showed a declining trend(P＜0.05).The highest drug resistance rate was observed for cefazolin(96.40％-98.38％),while the lowest was for tigecycline(0.44％—2.92％).Carbapenem-resistant E.cloacae demonstrated an increasing trend in drug resistance rates,with imipenem resistance ranging from 2.79％to 3.71％(P=0.044)and meropenem resistance ranging from 1.29％to 3.41％(P＜0.05).CONCLUSIONS The isolation rate of E.cloacae in Gansu Province remains stable,with a declining trend in drug resistance to multiple antibacterial drugs.However,the increasing drug resistance to carbapenems warrants attention.

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.

Objective　To assess the diagnostic efficacy of the cell-free Mycobacterium tuberculosis DNA testing (CF-TB) in tuberculous pleurisy. Methods　A total of 71 patients diagnosed with tuberculous pleurisy and 35 patients with non-tuberculous pleurisy were selected from the Fifth People's Hospital of Wuxi between January to December 2022. The standard pleural puncture was conducted to collect pleural effusion, which was then utilized for Mycobacterium tuberculosis culture, GeneXpert Mycobacterium tuberculosis/rifampicin resistance (GeneXpert MTB/RIF), CF-TB, and adenosine deaminase (ADA) testing. Blood samples were subjected to tuberculosis infection T-cell spotting test (T-SPOT.TB) assay. The receiver operator characteristic curve (ROC) was applied to obtain the optimal cut-off value for pleural fluid CF-TB and to compare the diagnostic performance of CF-TB with other methods. Data analysis was conducted using SPSS 22.0 software, with statistical significance defined as P<0.05. Results　The ROC curve analysis determined that the optimal cycle threshold (Ct) value for diagnosing tuberculous pleurisy using CF-TB in pleural fluid was 38.489, with a sensitivity of 91.5% and specificity of 97.1%. In comparison, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of T-SPOT.TB and pleural fluid ADA in diagnosing tuberculous pleurisy were 86.0%, 71.4%, 86.0%, 71.4%, 81.1%, and 55.0%, 91.4%, 92.9%, 50.8%, 67.0%, respectively, all of which were lower than the diagnostic efficiency of CF-TB. Furthermore, the specificity of pleural fluid CF-TB in diagnosing tuberculous pleurisy (97.1%) was not significantly different from GeneXpert MTB/RIF (100%) and Mycobacterium tuberculosis culture (100%), but its sensitivity (91.5%) was significantly higher than both GeneXpert MTB/RIF (19.7%) and Mycobacterium tuberculosis culture (28.2%), with a statistically significant difference (P<0.001). Conclusions　Compared to the conventional gold standard for diagnosing tuberculous pleurisy, CF-TB exhibits a higher sensitivity and its specificity is superior to that of tuberculosis immunological test. Consequently, CF-TB can serve as a valuable complement to other traditional detection methods in aiding the diagnosis of tuberculous pleurisy.

Objective To evaluate the clinical efficacy and safety of modified Weijing Decoction in the treatment of stable stage of bronchiectasis(phlegm heat accumulating in the lung pattern).Methods A series of N-of-1 trials using bronchiectasis patients in stable stage with phlegm heat accumulation in the lung pattern were performed.Participants meeting inclusion criteria underwent two distinct treatment protocols during a therapy period.Modified Weijing Decoction was used in the experimental period and ambroxol tablets were used in the control period,washout periods were set.The medication-use order in the control period and experimental period is random.The visual analog scale(VAS)was used to assess symptom changes before and after treatment.24-hour sputum volume and COPD self-assessment test(CAT)scores were recorded,while adverse reactions were monitored during the study period.Statistical analysis and drawing were performed on SPSS 25.0 and GraphPad Prism 8.Comparison of inter-group differences before grouping was assessed by independent samples t-test.Analysis of symptom score,24-hour sputum volume and CAT scores in the experimental and control periods,as well as comparison of differences between the above two groups before and after treatment were performed using paired t-test,which enabled comprehensive exploration of clinical and statistical distinctions.Results A total of 9 patients participated in 16 rounds of analysis.Statistically significant differences(P＜0.05)before and after the treatment in the experimental period were noted in total Traditional Chinese Medicine(TCM)symptom scores,cough,sputum,sputum color,chest tightness and chest pain,bitter and dry mouth,fatigue and tiredness,24-hour sputum volume,and CAT score.Paired t-tests revealed significant variations(P＜0.05)in the total TCM symptom scores,sputum color scores,scores of chest tightness and pain,and 24-hour sputum volume between experimental and control periods.No adverse events related to the test methods or drugs occurred during the observation period.Conclusion Modified Weijing Decoction could comprehensively improve clinical symptoms of bronchiectasis patients in stable stage.It exhibits superior efficacy compared to ambroxol,and maintains a favorable safety profile.

Objective:To analyze the distribution of clopidogrel metabolism-related gene variability in Kawasaki disease (KD) children with coronary artery lesions (CAL) across different age groups and the impact of genetic variability on the efficacy of clopidogrel antiplatelet therapy.Methods:A retrospective cohort study was conducted. Clinical data were collected from 46 KD children with CAL who were hospitalized in the Cardiovascular Center of Children′s Hospital of Fudan University between January 2021 and August 2022 and were treated with clopidogrel, including gender, age, body mass index, course of KD, CAL severity grade, and baseline platelet count. According to their age, the children were divided into ≥2-year-old group and <2-year-old group. Their platelet responsiveness was assessed by adenosine diphosphate-induced platelet inhibition rate (ADPi) calculated via thromboelastography, and children were categorized into high on-treatment platelet reactivity (HTPR) and normal on-treatment platelet reactivity (NTPR) groups. Genotypes of CYP2C19, PON1 and ABCB1 were detected. The t test, one-way analysis of variance and Chi-square test were used for intergroup comparison. Results:Among the 46 KD children with CAL, 34 were male and 12 were female; 37 were ≥2-year-old and 9 were <2-year-old; 25 cases were in the HTPR group and 21 cases were in the NTPR group, with 19 HTPR and 18 NTPR in the ≥2-year-old group, and 6 HTPR and 3 NTPR in the <2-year-old group. Genetic analysis showed that 92 alleles among the 46 children, with frequencies of CYP2C19*1, CYP2C19*2, CYP2C19*3, CYP2C19*17, PON1 192Q, PON1 192R, ABCB1 3435C, ABCB1 3435T at 59% (54/92), 32% (29/92), 9% (8/92), 1% (1/92), 36% (36/92), 64% (59/92), 63% (58/92) and 37% (34/92), respectively. Analysis of the impact of genotype on ADPi revealed that in children aged ≥2 years, those with CYP2C19*1/*3 genotype had significantly lower ADPi than those with CYP2C19*1/*1 genotype ((34±15)% vs. (61±29)%, t=2.18, P=0.036). There were also no significant difference in ADPi among children with PON1 192Q homozygous, PON1 192R heterozygote and PON1 192R homozygous genotypes ((40±22)% vs. (52±33)% vs. (65±27)%, F=2.17, P=0.130), or among those with ABCB1 3435C homozygous, ABCB1 3435T heterozygote and ABCB1 3435T homozygous genotypes ((55±34)% vs. (60±27)% vs. (49±24)%, F=0.33, P=0.719). In <2-year-old group, there were no significant differences in ADPi across CYP2C19*1/*1, CYP2C19*1/*2 and CYP2C19*2*2 genotypes ((40±20)% vs. (53±37)% vs. (34±16)%, F=0.37, P>0.05). There were no significant differences in ADPi across CYP2C19*1/*1 and CYP2C19*1/*3 genotypes ((44±27)% vs. (42±20)%, t=0.08, P>0.05). There were no significant differences in ADPi across PON1 192Q homozygous, PON1 192R heterozygote and PON1 192R homozygous genotypes (45% vs. (55±27)% vs. (24±5)%, F=1.83, P>0.05). There were no significant differences in ADPi across ABCB1 3435C homozygous, ABCB1 3435T heterozygote and ABCB1 3435T homozygous genotypes ((36±16)% vs. (50±35)% vs. 45%, F=0.29, P>0.05). The risk analysis of HTPR in different genotypes revealed that in children aged ≥2 years, carrying at least 1 or 2 loss-of-function alleles of CYP2C19 was a risk factor for HTPR ( OR=4.69, 10.00, 95% CI 1.11-19.83, 0.84-119.32, P=0.033, 0.046, respectively), and PON1 192R homozygosity and carrying at least one PON1 192R allele were protective factors against HTPR ( OR=0.08, 0.13, 95% CI 0.01-0.86, 0.01-1.19, P=0.019, 0.043, respectively). Conclusion:KD children aged ≥2 years carrying CYP2C19 loss-of-function alleles and PON1 192Q are more likely to develop HTPR.
