By systematically combing ancient and modern literature， this paper examined Tribuli Fructus and Astragali Complanati Semen（ACS） used in the famous classical formulas from the aspects of name， origin， production area， harvesting and processing， clinical efficacy， so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology， and there were nicknames such as Baijili， Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas， and there were nicknames such as Baijili， Shayuan Jili and Tongjili. Because both of them had the name of Baijili， confusion began to appear in the Song dynasty. In ancient and modern times， the main origin of Tribuli Fructus were Tribulus terrestris， and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu， but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part， harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times， and the plump， firm texture， grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing， while modern commonly used is purified， fried and salt-processed. The ancient records of Tribuli Fructus were spicy， bitter， and warm in nature， with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders， improving vision， promoting muscle growth， and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today， the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed， traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter， followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior， while modern standards prioritize plump， uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying， while modern practice commonly employs purification methods. In terms of medicinal properties， the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus， its effects were thus regarded as equivalent to those of Tribuli Fructus， serving as the medicine for treating wind disorders， additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang， solidify sperm and reduce urine， nourish the liver and brighten the eye， etc. Based on the textual research results， it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials， we should pay attention to the specific reference object of Baijili， T. terrestris and A. complanatus should be identified and selected， and the processing method should be in accordance with the requirements of the formulas.

Objective:To observe the effects of acupuncture and moxibustion on interleukin(IL)-9/IL-9 receptor(IL-9R)in the colon tissue of rats with ulcerative colitis(UC)and investigate the protective mechanism of acupuncture and moxibustion on the intestinal mucosal barrier in UC rats. Methods:Male Sprague-Dawley rats were randomly divided into a normal control(NC)group and a modeling group.UC models were prepared by giving 4%dextran sulfate sodium(DSS)water for 7 d.After the successful construction of the UC rat model,the modeling group was randomly divided into a UC group,a herb-insulated moxibustion(HM)group,and an electroacupuncture(EA)group.HM and EA interventions at bilateral Tianshu(ST25)were performed once a day for 7 d.Hematoxylin-eosin(HE)staining was used to observe the histopathological changes in the colon.The serum concentrations of IL-9,IL-6,IL-1β,and hemoglobin-H(HbH)were determined by enzyme-linked immunosorbent assay.The protein expression levels of IL-9,IL-9R,claudin-2,zonula occludens-1(ZO-1),and occludin in the colon tissue were measured by Western blotting or immuno-histochemistry.Immunofluorescence was used to detect the co-expression of PU.1 and CD4 with the IL-9 protein. Results:Compared with the NC group,the colon tissue of UC rats was severely damaged and ulcerated with congestion and edema,and the colonic histopathological score increased significantly(P<0.01).The serum HbH concentration decreased significantly(P<0.01),while the serum concentrations of IL-9,IL-6,and IL-1β increased(P<0.01).The protein expression of colonic ZO-1 and occludin decreased significantly(P<0.01),while the protein expression of colonic IL-9 and IL-9R increased(P<0.05).The positive co-expression levels of IL-9/PU.1 and IL-9/CD4 increased in the colon tissue(P<0.05).Compared with the UC group,the colonic mucosal structures were gradually repaired in both HM group and EA group,and healed ulcers could be observed,the colonic histopathological score decreased significantly(P<0.05).The serum concentration of HbH increased(P<0.01),while the serum concentrations of IL-9,IL-6,and IL-1β decreased(P<0.05).The protein expression levels of ZO-1 and occludin increased(P<0.05),while the protein expression levels of IL-9 and IL-9R decreased(P<0.01).The positive co-expression levels of IL-9/PU.1 and IL-9/CD4 decreased in the colon tissue(P<0.05). Conclusion:Both HM and EA can inhibit the protein expression levels of IL-9 and IL-9R in the UC colon by regulating the transcription factor PU.1,promote the repair of intestinal mucosal barrier,and down-regulate protein contents of proinflammatory factors IL-9,IL-6,and IL-1β in the serum,which may be one of the key mechanisms of acupuncture and moxibustion in reducing the inflammation of UC colonic mucosa and protecting the intestinal mucosal barrier.

To address the shortcomings of traditional hydrogels in terms of mechanical performance and environmental stability,a new conductive organogel based on polyvinyl alcohol(PVA)and polypyrrole(PPy)was prepared in this study.By introducing dimethyl sulfoxide(DMSO)as a solvent,the mechanical strength and durability of the gel were significantly improved.Various characterization techniques,including infrared spectroscopy,thermogravimetric analysis,and scanning electron microscopy were used to characterize this conductive organogel.The experimental results showed that the prepared organogel exhibited optimal performance at PVA concentration level of 8%(m/m),with an average pore size of 5.2 μm and a conductivity of 0.65 S/cm.As a wearable strain sensor,the PVA/PPy organogel demonstrated excellent sensitivity and responsiveness,capable of precisely detecting joint and muscle movements as well as subtle physiological signals such as pulse and vocal cord vibrations.Notably,the gel maintained stable sensing performance even after 48 h at room temperature,showing outstanding environmental adaptability and long-term use potential.This innovative material design provided robust technical support for smart healthcare,health monitoring,and human-machine interaction,showing broad application prospects.

Objective:To investigate the efficacy and safety of protein A immunoadsorption (PAIA) combined with rituximab (RTX) in highly sensitized patients who underwent haplo-hematopoietic stem cell transplantation (haplo-HSCT) .Methods:The clinical data of 56 highly sensitized patients treated with PAIA and RTX before haplo-HSCT at the First Affiliated Hospital of Soochow University and Soochow Hopes Hematonosis Hospital between March 2021 and June 2023 were retrospectively analyzed. The number of human leukocyte antigen (HLA) antibody types and the mean fluorescence intensity (MFI), humoral immunity, adverse reactions during adsorption, and survival within 100 days before and after adsorption were measured.Results:After receiving the PAIA treatment, the median MFI of patients containing only HLA Ⅰ antibodies decreased from 7 859 (3 209-12 444) to 3 719 (0-8 275) ( P<0.001), and the median MFI of HLA Ⅰ+Ⅱ antibodies decreased from 5 476 (1 977-12 382) to 3 714 (0-11 074) ( P=0.035). The median MFI of patients with positive anti-donor-specific antibodies decreased from 8 779 (2 697-18 659) to 4 524 (0–15 989) ( P<0.001). The number of HLA-A, B, C, DR, and DQ antibodies in all patients decreased after the PAIA treatment, and the differences were statistically significant (A, B, C, DR: P<0.001, DQ: P<0.01). The humoral immune monitoring before and after the PAIA treatment showed a significant decrease in the number of IgG and complement C3 ( P<0.001 and P=0.002, respectively). Forty-four patients underwent HLA antibody monitoring after transplantation, and the overall MFI and number of antibody types decreased. However, five patients developed new antibodies with low MFI, and nine patients continued to have high MFI. The overall survival, disease-free survival, non-recurrent mortality, and cumulative recurrence rates at 100 days post-transplantation were 83.8%, 80.2%, 16.1%, and 4.5%, respectively. Conclusions:The combination of PAIA and RTX has a certain therapeutic effect and good safety in the desensitization treatment of highly sensitive patients before haplo-HSCT.

The hyperacute stage of myocardial infarction refers to a period of time within 30 minutes after the occurrence of myocardial infarction, when the symptoms are not obvious and the diagnosis is difficult, and the related pathophysiological mechanism has received less attention. In this study, proteomics was used to investigate the pathological changes in the early hyperacute phase of myocardial infarction, aiming to provide experimental evidence for pathological mechanism of myocardial infarction hyperacute stage. Meanwhile, the intervention effect and related mechanism of salvianolate injection were discussed based on heat shock protein B6 (HSPB6), aiming to benefit the clinical rational use of salvianolate injection. The protein expression changes before and after myocardial infarction model establishment were detected by label-free proteomics via mass spectrometry and analyzed by bioinformatics method. Then the binding effect of salvianolate injection on the commonly differential protein HSPB6 was evaluated by molecular docking technology, which was finally verified by animal experiments. All animal experimental protocols were approved by the Ethics Committee of Xiyuan Hosptial (2022XLC041). The results of this study showed that a total of 2 166 proteins were quantified by lable-free proteomics, of which 194 shared differential proteins were involved in myocardial injury and body regulation in the hyperacute phase of myocardial infarction, mainly involving molecular functions such as protein homodimerization activity, oxygen binding and transport, and serine endopeptidase inhibitor activity. Among them, HSPB6 protein is involved in the regulation of myocardial function. Molecular docking results indicated that magnesium salvianolate acetate, which is the main component of salvianolate injection, had the lowest binding energy with HSPB6 protein: -14.53 kcal·mol^-1. Animal experiments showed that compared with the Sham group, the model group had significantly lower ejection fraction (EF) and fractional shortening (FS) (P < 0.001), cardiac blood perfusion decreased significantly (P < 0.001). There were obvious pathological changes such as myocardial fiber disorder, cardiomyocyte edema and interstitial small blood vessel congestion; the injury of cardiac function of rats in the administration group was attenuated, and the FS of rats in the low-dose group was significantly improved (P < 0.05), the pathological injury of myocardial tissue was markedly mitigated, and the expression of HSPB6 protein was up-regulated to varying degrees (P < 0.01, P < 0.001). In conclusion, salvianolate injection could be able to improve the cardiac function and pathological morphology of rats in the early hyperacute stage of myocardial infarction, and its mechanism may be related to the promotion of expression of HSPB6.

OBJECTIVE: To explore the genetic etiology for a child with profound intellectual disabilities and obvious behavioral abnormalities. METHODS: A male child who had presented at the Zhongnan Hospital of Wuhan University on December 2, 2020 was selected as the study subject. Peripheral blood samples of the child and his parents were collected and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing. Short tandem repeat (STR) analysis was carried out to determine its parental origin. The splicing variant was also validated in vitro with a minigene assay. RESULTS: WES results revealed that the child had harbored a novel splicing variant of c.176-2A>G in the PAK3 gene, which was inherited from his mother. The results of minigene assay have confirmed aberrant splicing of exon 2. According to the guidelines from the American College of Medical Genetics and Genomics, it was classified as a pathogenic variant (PVS1+PM2_Supporting+PP3). CONCLUSION The novel splicing variant c.176-2A>G of the PAK3 gene probably underlay the disorder in this child. Above finding has expanded the variation spectrum of the PAK3 gene and provided a basis for genetic counseling and prenatal diagnosis for this family.

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

Platelets are reprogrammed by cancer via a process called education, which favors cancer development. The transcriptional profile of tumor-educated platelets (TEPs) is skewed and therefore practicable for cancer detection. This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n = 3; Netherlands, n = 5; Poland, n = 1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, and early-stage ovarian cancer. However, these observations warrant prospective validations in a larger population before clinical utilities.
