[Objective] To establish a new scoring system to predict the perioperative outcomes (operation time, intraoperative blood loss, and trifecta achievement) in patients undergoing robot-assisted partial nephrectomy (RAPN) by integrating the RENAL and Mayo adhesive probability (MAP) scores. [Methods] Clinical data of 178 patients with renal cell carcinoma who underwent RAPN performed by the same surgeon in our hospital during Jan.2015 and Jan.2022 were retrospectively analyzed.The RENAL and MAP scores of all patients were calculated.Linear regression and logistic regression were used to evaluate the associations between the components of the RENAL and MAP scores (a total of 6 variables) and perioperative outcomes.The factors with significant associations were then included into logistic regression analysis to identify independent predictors for constructing an assessment system for perioperative outcomes, and the receiver operating characteristic (ROC) curve was plotted to calculate the area under the curve (AUC) to predict its efficacy. [Results] Multivariate linear regression analysis showed that tumor size (β=6.14, 95%CI: 1.93—10.34, P=0.004), exophytic rate (β=10.60, 95%CI: 3.44—17.76, P=0.004), and perinephric fat thickness (β=16.48, 95%CI: 8.52—24.45, P<0.001) were significantly associated with operation time.Tumor size (β=10.55 95%CI: 5.60—15.49, P<0.001) was associated with both intraoperative blood loss and trifecta achievement (OR=1.73, 95%CI: 1.26—2.36, P=0.001). Multivariate logistic regression analysis of these 3 factors identified tumor size (OR=9.07, 95% CI: 1.18—69.45, P=0.03) and perinephric fat thickness (OR=2.28, 95%CI: 1.86—6.04, P=0.01) as independent predictors of perioperative outcomes.Based on these findings, the tumor size and perinephric fat thickness (RP) scoring was constructed, which demonstrated better predictive ability than RENAL score or MAP score alone (RP vs.RENAL vs.MAP: 0.766 vs.0.548 vs.0.684). [Conclusion] The RP score includes fewer variables than the RENAL and MAP scores but outperforms them.

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine (TCM). The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology, Western medicine obstetrics and gynecology, and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion, the experts concluded that chromosome, endocrine, and immune abnormalities were the key factors for the occurrence of threatened abortion, and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion, TCM has advantages in preventing miscarriages, alleviating clinical symptoms and TCM syndromes, relieving anxiety, regulating reproductive endocrine and immune abnormalities, personalized and diversified treatment, enhancing efficiency and reducing toxicity, and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

ObjectiveTo investigate the possible mechanism of Buzhong Yulin Decoction (补中愈淋汤) in the prevention and treatment of recurrent urinary tract infection. MethodsThe mouse models of recurrent urinary tract infection were established by uropathogenic Escherichia coli (UPEC) strain UTI89 by bladder perfusion, and the successful mouse models were randomly divided into a model group, an antibiotic group, and a low- and high-dose Buzhong Yulin Decoction group, with six mice in each group. In addition, 5 C57BL/6 mice without modelling were taken as blank group. The low- and high-dose Buzhong Yulin Decoction groups received 0.1 ml/10 g of decoction by gavage, with concentrations of 1.3 g/ml and 5.2 g/ml, respectively; the antibiotic group received 0.1 ml/10 g of levofloxacin hydrochloride solution with 5 mg/ml by gavage; the blank and model groups received 0.1 ml/10 g of distilled water by gavage. Each group was gavaged once a day for 7 consecutive days. The total number of urine marks, the number of central urine marks, and the total urine volume of the urine marks were observed by the urine marking test; HE staining was used to observe the histopathological changes in the bladder of mice; serum levels of the inflammatory factors interleukin 1β (IL-1β), interleukin 6 (IL-6) and tumour necrosis factor α (TNF-α) were detected by ELISA; the morphology of the epithelial cells of bladder was observed by scanning electron microscopy; immunofluorescence assay to detect bladder tissue anti-UroPlakin 3A protein level and UPEC bacterial load; the spread plate method to detect urinary bacterial load and bacterial load of bladder epithelial cells; RT-PCR method to detect Ras-related protein Rab-11A (RAB11A) and Ras-related protein Rab-27B (RAB27B) mRNA level in bladder tissue; immunoblotting to detect microtubule-associated protein 1 light chain3 (LC3) and P62 protein levels in bladder tissue. ResultsCompared with the blank group, the bladder epithelial cell layers were lost and showed abnormal morphology in mice of the model group; bladder tissue UroPlakin 3A protein and RAB11A and RAB27B mRNA levels reduced, the total number of urine marks, the number of central urine marks, bladder tissue UPEC bacterial load, urinary bacterial load, bacterial load in bladder epithelial cells, serum IL-1β, IL-6, and TNF-α levels, and LC3 and P62 protein levels in bladder tissue all elevated (P<0.05 or P<0.01). Compared with the model group, the bladder epithelial cell layers were intact and the morphology of epithelial cells were regular in the low- and high-dose Buzhong Yulin Decoction groups; the average surface area of bladder epithelial cells reduced, the levels of UroPlakin 3A protein and RAB11A and RAB27B mRNA in bladder tissues elevated, and total number of urine marks, the number of central urine marks, bladder tissue UPEC bacterial load, urinary bacterial load, bacterial load in bladder epithelial cells, serum IL-1β, IL-6, and TNF-α levels, and P62 protein levels in bladder tissue all reduced (P<0.05 or P<0.01), but LC3 protein levels showed no statistically significant (P>0.05). In the antibiotic group, the bladder epithelial cells were partially missing and the morphology of epithelial cells was abnormal. Compared with the antibiotic group, the average surface area of the bladder epithelial cells in the mice increased in the low- and high-dose Buzhong Yulin Decoction groups, the bacterial load of the bladder epithelial cells decreased, and the P62 protein level of the bladder tissue decreased (P<0.05). When comparing between the low- and high-dose Buzhong Yulin Decoction groups, the differences in each index were not statistically significant (P>0.05). ConclusionBuzhong Yulin Decoction may prevent and treat recurrent urinary tract infection by repairing the bladder mucosal barrier, increasing RAB11A and RAB27B level and enhancing autophagy in bladder tissues, thereby facilitating bacterial clearance from bladder epithelial cells and reducing the bacterial load of bladder epithelial cells.

ObjectiveTo observe the therapeutic effects of Qishao Huoxue prescription on patients with lumbar disc herniation due to Qi stagnation and blood stasis and the effects of this prescription on hemorheological parameters and serum levels of inflammatory mediators. MethodA total of 86 patients with lumbar disc herniation due to Qi stagnation and blood stasis treated in the Wangjing Hospital of China Academy of Chinese Medical Sciences from January 2023 to February 2024 were selected and assigned according to the random number table into observation and control groups (n=43). Patients in both groups received lumbar traction treatment. In addition, the observation group was orally treated with Qishao Huoxue prescription and the control group with celebrex for 3 weeks. The visual analogue scale (VAS) score, Oswestry disabilitiy index (ODI) score, 12-item Short-Form Survey (SF-12) score, traditional Chinese medicine (TCM) symptom score, hemorheological parameters [whole blood high shear viscosity, middle shear viscosity, low shear viscosity, plasma viscosity (PV), and fibrinogen (FIB)], and the serum levels of inflammatory mediators [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), and transforming growth factor-β1 (TGF-β1)] were determined before and after treatment. In addition, the clinical efficacy and adverse reactions were observed and compared between the two groups. ResultAfter treatment, both groups showed declined VAS, ODI, and TCM symptom scores (P<0.05), increased SF-12 physical component summary (PCS) and mental component summary (MCS) scores (P<0.05). After treatment, the whole blood high shear viscosity, middle shear viscosity, low shear viscosity, PV, and FIB decreased in the observation group (P<0.05), while they did not show significant variations in the control group. After treatment, both groups of patients showed reductions in TNF-α, IL-6, and IL-1β levels and an elevation in the TGF-β1 level (P<0.05). Compared with the control group after treatment, the observation group showed decreases in VAS, ODI, TCM symptom scores and main symptom scores (P<0.05), no significant differences in the secondary symptom scores, increased PCS and MCS scores (P<0.05). The observation group outperformed the control group in terms of recovering whole blood high shear viscosity, middle shear viscosity, low shear viscosity, PV, FIB, TNF-α, IL-6, IL-1β, and TGF-β1 (P<0.05). The total response rate in the observation group was 97.5% (40/41), which was higher than that (88.1%, 37/42) in the control group (P<0.05). No serious adverse reaction was observed in the two groups during the observation period. One case in the observation group showed subcutaneous bruising on the lower limbs, which gradually disappeared after withdrawal. ConclusionQishao Huoxue prescription demonstrated definite effect in treating lumbar disc herniation due to qi stagnation and blood stasis by recovering hemorheological parameters and inhibiting the expression of inflammatory mediators in the serum without inducing adverse reactions. It is worth applying in clinical practice.

This study using maltodextrin as raw material, 1%-5% polyvinylpyrrolidone K30 as template agent, 1%-5% ammonium bicarbonate as pore-forming agent, curcumin and ibuprofen as model drugs. Porous maltodextrin was prepared by template and pore-forming agent methods, respectively. The structure and drug delivery behavior of porous maltodextrin prepared by different technologies were comprehensively characterized. The results showed that the porous maltodextrin prepared by pore-forming agent method had larger specific surface area (6.449 4 m2·g-1) and pore size (32.804 2 nm), which was significantly better than that by template agent method (3.670 2 m2·g-1, 15.278 5 nm). The adsorption kinetics between porous maltodextrin prepared by pore-forming agent method and curcumin were suitable for quasi-first order adsorption kinetic model, and that between porous maltodextrin and ibuprofen were suitable for quasi-second order adsorption kinetic model. While the adsorption kinetics between porous maltodextrin prepared by template agent method and two model drugs were both suitable for the quasi-first order adsorption kinetic model. In addition, the dissolution behavior analysis showed that the porous maltodextrin prepared by the two technologies can significantly improve the dissolution behavior of insoluble drugs, and the drug release was both carried out by diffusion mechanism, which suitable for the Peppas kinetic release model, but the porous maltodextrin prepared by template agent method had a faster release rate. The change of nozzle diameter had no significant effect on the adsorption process and drug release behavior of porous maltodextrin. In conclusion, the porous maltodextrins prepared by two different technologies were both beneficial to the delivery of insoluble drugs, and the template agent method was the best for delivery of insoluble drugs. This study can provide theoretical basis for the preparation of porous particles, promote the application of porous particles in insoluble drugs, and improve the bioavailability of insoluble drugs.

Exploring the risk "time interval window" of sequential medication of Reduning injection (RDN) and penicillin G injection (PG) by detecting the correlation between serum biochemical indexes and plasma metabonomic characteristics, in order to reduce the risk of adverse reactions caused by the combination of RDN and PG. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). The changes of biochemical indexes in serum of rats were detected by enzyme-linked immunosorbent assay. It was determined that RDN combined with PG could cause pseudo-allergic reactions (PARs) activated by complement pathway. Further investigation was carried out at different time intervals (1.5, 2, 3.5, 4, 6, and 8 h PG+RDN). It was found that sequential administration within 3.5 h could cause significant PARs. However, PARs were significantly reduced after administration interval of more than 4 h. LC-MS was used for plasma metabolomics analysis, and the levels of serum biochemical indicators and plasma metabolic profile characteristics were compared in parallel. 22 differential metabolites showed similar or opposite trends to biochemical indicators before and after 3.5 h. And enriched to 10 PARs-related pathways such as arachidonic acid metabolism, steroid hormone biosynthesis, linoleic acid metabolism, glycerophospholipid metabolism, and tryptophan metabolism. In conclusion, there is a risk "time interval window" phenomenon in the adverse drug reactions caused by the sequential use of RDN and PG, and the interval medication after the "time interval window" can significantly reduce the risk of adverse reactions.

[Objective] To determine the feasibility of preparing plasminogen (Pg) with Fraction Ⅲ precipitation (hereinafter referred to as FⅢ-P) from low-temperature ethanol process by full chromatography (hereinafter referred to as FⅢ-P process). [Methods] The FⅢ-P was diluted with dissolution buffer at different dilution times and stirring time. The potency and antigen concentration of Pg in dissolution sample were detected and the dissolution and clarification conditions were determined. Pre-treatment of loading sample and pre-experiment of affinity chromatography were carried out on the FⅢ-P dissolution sample to judge whether the loading sample had an impact on the chromatography by observing the performance of the affinity chromatography column and to evaluate whether the affinity chromatography could achieve the purpose of purifying Pg by detecting the plasma protein antigen concentration and Pg potency of the samples in the process. Two batches of FⅢ-P process were studied step by step, and the specific activity, steps and total recovery, and the output of Pg per ton of plasma were calculated. The feasibility of preparing Pg by FⅢ-P process was evaluated by comparing with the data of full chromatography process using plasma as raw material (hereinafter referred to as plasma process). [Results] The FⅢ-P was dissolved with 10 times of dissolution buffer, stirred for 1 hour, centrifuged at room temperature of 10 000×g for 15 minutes. The supernatant was first filtered with a screen, then clarified with an 8/0.8 μm filter, and finally filtered with a 0.45/0.2 μm filter and loaded. Pre-test showed that from clarification and filtration to Pg affinity chromatography, the step recovery of activity and antigen was 39.51% and 108.64%, respectively, the antigen concentration of Pg increased by 31.16 times and the activity increased by 11.39 times after affinity chromatography, which reaching the effect of affinity chromatography purification of Pg. The results of 2 batches of step-by-step scale-up FⅢ-P process showed that the total recoveries of antigen and activity from plasma to SP chromatography of FⅢ-P process were (45.76±1.10)% and (24.15±0.59)%, respectively, which had a total loss of about 1/3 of antigen and about 2/3 of activity compared to the plasma process. The Pg specific activity of SP chromatography eluent was (4.68±0.25) U/mg, which was about half of that of plasma process, but meeted the internal standard of > 4 U/mg. The output of Pg antigen per ton of plasma in the FⅢ-P process was 68.73% of that in the plasma process, and the output of Pg activity per ton of plasma in the plasma process was 29.82% of that in the plasma process, which basically achieved the purpose of waste utilization of FⅢ-P. [Conclusion] The technical route of preparing Pg from FⅢ-P by full chromatography is feasible.
