ObjectiveTo provide a reference for the rational clinical use of cold Chinese medicines by sorting and analyzing their properties， flavors， meridian tropism， primary therapeutic indications， methods of administration， dosages， and precautions as recorded in the 2020 edition of Pharmacopoeia of the People's Republic of China （Chinese Pharmacopoeia）. MethodsCold Chinese medicines for internal and external use included in the 2020 edition of Chinese Pharmacopoeia were entered one by one， and their efficacy， properties， flavors， meridian tropism， methods of administration， dosages， and usage precautions were statistically classified and summarized to guide clinical medication use. ResultsA total of 259 cold Chinese medicines for internal use were included and categorized into 18 efficacy groups， mainly comprising heat-clearing drugs， water-excreting and dampness-draining drugs， and phlegm-resolving， cough- and asthma-relieving drugs. Their predominant flavors were bitter， sweet， and pungent， and they primarily entered the liver， lung， and stomach meridians. The main methods of administration included decocting first， grinding into powder for oral use， or preparing into pills or powders， with most dosages ranging from 9 to 15 g. A total of 83 cold Chinese medicines for external use were included， involving 16 efficacy categories. Their main flavors were bitter， sweet， and pungent， primarily entering the liver， lung， and large intestine meridians. The main external application methods were grinding into powder for topical use or preparing decoctions for fumigation and washing， with most dosages ranging from 9 to 15 g. Whether for internal or external use， cold Chinese medicines should be used with caution or contraindicated in pregnant women. ConclusionThe cold Chinese medicines included in the 2020 edition of the Chinese Pharmacopoeia are mainly suitable for patients with carbuncles， swellings， and coughs. However， in clinical practice， it is necessary to strictly follow the principles of syndrome differentiation and treatment， pay attention to administration methods and dosages， and use cold medicines rationally and effectively to improve clinical efficacy.

ObjectiveTo investigate the effect of solute carrier family 7 member 5 (SLC7A5) inhibitor JPH203 on renal fibrosis induced by unilateral ureteral obstruction in mice. MethodsSixteen SPF male C57BL/6 mice were randomly divided into the control group and the experimental group, with 8 mice in each group. The mouse model of renal fibrosis was established by unilateral ureteral obstruction. From the third day after surgery, the mice in the control group were intraperitoneally injected with phosphate-buffered saline (PBS) for 11 consecutive days, and the injection dose was 200 μL/d. Mice in the experimental group received intraperitoneal injection of JPH203 (50 mg/kg) every day for 11 days. On day 14, the mice were euthanized, then the kidney tissues were obtained. Hematoxylin and eosin (HE) staining was used to assess renal tissue damage, Masson staining was used to evaluate collagen fiber deposition in the extracellular matrix, and immunohistochemistry was used to detect the levels of fibroblast activation markers α-smooth muscle actin (α-SMA) and collagen type Ⅰ (COL-Ⅰ) in kidney tissues. Western blotting was further performed to measure the expression levels of SLC7A5 and transforming growth factor-β1 (TGF-β1), as well as the phosphorylation levels of mammalian target of rapamycin complex 1 (mTORC1) signaling pathway-related molecules. Real-time quantitative PCR was used to verify changes in the mRNA levels of SLC7A5, α-SMA, and COL-Ⅰ in kidney tissues. ResultsCompared with the control group, the experimental group showed reduced destruction of renal tissue structure and a significantly lower pathological injury score (P<0.05). Additionally, collagen deposition in the extracellular matrix was decreased, and the percentage of collagen fiber area was significantly reduced (P<0.001) in the experimental group. The levels of fibroblast activation markers α-SMA and COL-Ⅰ were significantly lower in the experimental group (both P<0.001). The expression levels of SLC7A5 and TGF-β1 were also significantly decreased (P<0.001), and the phosphorylation levels of mTORC1 signaling pathway-related proteins 4E-BP1 and mTORC1 were significantly reduced (P<0.001). Real-time quantitative PCR confirmed that the mRNA levels of SLC7A5, α- SMA, and COL-Ⅰ in kidney tissues were significantly lower in the experimental group (P<0.001). ConclusionJPH203 may inhibit the progression of renal fibrosis in mice by suppressing SLC7A5 expression, regulating the mTORC1 signaling pathway, and altering fibroblast activation status.

Hepatocellular carcinoma (HCC) develops within a profoundly immunosuppressive tumor immune microenvironment (TIME), which limits the efficacy of immunotherapy. Polarization of tumor-associated macrophages (TAMs) toward a pro-tumorigenic M2 phenotype is a major driver of immune escape. Ferroptosis, an iron-dependent regulated cell death program, intersects with hepatic iron metabolism and immune regulation and thus offers promising points of therapeutic intervention. This review systematically elucidates the mechanistic role of TAM ferroptosis in HCC immune evasion and highlights a “bidirectional regulation” intervention strategy grounded in the Traditional Chinese medicine (TCM) principle of “fortifying healthy qi and eliminating pathogens” (Fuzheng Quxie). This strategy employs “eliminating pathogens” (Quxie) approaches to exploit the metabolic vulnerability of M2-like TAMs and precisely induce their ferroptosis. Moreover, it utilizes “fortifying healthy qi” (Fuzheng) approaches to protect M1-like TAMs and CD8⁺ T cells from oxidative damage. This parallel “induction-protection” paradigm demonstrates the unique advantages of TCM in systemically remodeling TIME through multitarget synergistic actions. Accordingly, precision regulation of TAM ferroptosis based on the Fuzheng Quxie theory represents a promising integrative Chinese-Western medicine strategy for overcoming current bottlenecks in HCC immunotherapy, although its clinical translational potential warrants further validation.

Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Objective:To explore the potential mechanism of action of Xian Fang Huo Ming Yin modified formula(XFHMY)in the treatment of medication-related osteonecrosis of the jaw(MRONJ)through bioinformatics analysis and in vitro and in vivo experiments.Methods:Firstly,the efficacy of XFHMY was evaluated by establishing a mice model of MRONJ induced by zoledronic acid(ZOL);Subsequently,the potential molecular mechanism of XFHMY in the treatment of MRONJ was predicted by using network pharmacology;Lastly,the network pharmacology prediction results were collectively validated through MC3T3-E1 cell proliferation and differentiation experiments,Western blot analysis,and immunohistochemical staining of mouse maxillary bone tissue.Results:Animal experiments showed that,compared to the model group,the XFHMY group exhibited significantly improved wound healing in the tooth extraction socket(P＜0.001),a significant reduction in bone volume fraction and empty lacunae rate in the maxilla(P＜0.0001,P＜0.001),and a significant increase in trabecular separation and osteoclast number(P＜0.01,P＜0.05).Network pharmacology analysis identified 59 common targets,with both GO and KEGG analyses indicating the Wnt/β-catenin signaling pathway as a crucial mechanism for XFHMY in treating MRONJ.Ten key active components,including quercetin,luteolin,and fisetin,were screened,and these compounds demonstrated strong binding affinity with CTNNB1,a core target of this pathway.In vitro experiments revealed that XFHMY(0.25,0.5,1,2,4 mg/mL)promoted MC3T3-E1 cell proliferation(P＜0.0001)and activated the Wnt/β-catenin pathway by upregulating β-catenin and Runx2 protein expression,thereby reversing ZOL-induced inhibition of MC3T3-E1 cell proliferation and differentiation while enhancing both processes.Immunohistochemical analysis of mouse maxillae showed that,compared to the model group,the XFHMY group had significantly increased β-catenin and Runx2 protein expression(P＜0.05,P＜0.01),consistent with the in vitro findings.Conclusion:XFHMY promotes the proliferation and differentiation of osteoblasts through activating the Wnt/β-catenin signaling pathway,which in turn attenuates MRONJ.The novel pharmacological mechanism proposed in this study provides a theoretical basis for the clinical application of XFHMY.

Objective The exploration of the mediating effect of chromium exposure on the blood routine indicators of diabetes patients is limited.This study aims to explore the possible mediating path by using the conditional process mediation model.Methods The study was based on the results of cross－sectional data in 2018 in the environmental chromium exposure and population health research database provided by the Institute of Basic Medicine of the Chinese Academy of Medical Sciences.A total of 436 patients were selected in this study according to the emission criteria.SPSS 24.0 and SPSS plug－in Process are selected and applied to the construction of demographic data and intermediary model respectively.Result In the conditional process analysis with total bilirubin as the regulatory variable,total bilirubin had a positive regulatory effect on the path of urine chromium→total protein and urine chromium → LDL.In the conditional process analysis with blood glucose as the regulatory variable,blood glucose had a positive regulatory effect on urine chromium → total protein and LDL→ total protein pathways.In the conditional process analysis using both blood glucose and total bilirubin as regulatory variables,blood glucose and total bilirubin had a positive regulatory effect on the LDL→ total protein pathway.Conclusion Diabetes patients with chromium exposure history should focus on the effects of LDL,total bilirubin and blood glucose levels on TP,which is conducive to preventing liver injury in diabetes patients and improving their disease prognosis and quality of life.

Objective To explore the feasibility and efficacy of single-balloon enteroscope in the diagnosis and treatment of calculous small intestinal obstruction.Methods A retrospective analysis was performed on the clinical data of 16 patients who underwent endoscopic enterolith removal for small intestinal obstruction from July 2013 to December 2023.The outcomes of stone removal and therapeutic efficacy were evaluated.Results All the 16 patients successfully underwent single-balloon enteroscope.Among them,15 cases achieved successful stone extraction,while 1 case failed due to an oversized stone that could not pass through the pharyngoesophageal junction.The stone was subsequently pushed to the stomach and removed through surgical operation finally.Conclusion Single-balloon enteroscope has excellent efficacy in enterolith removal,with rapid postoperative recovery and less complications.It is worthy of widespread clinical application.

Objective To explore the impacts of remimazolam on intraoperative intracranial pressure(ICP)and cerebral oxygenation in patients undergoing laparoscopic lower abdominal and pelvic surgery under CO2 pneumoperitoneum combined with Trendelenburg position.Methods Eighty-eight patients scheduled to undergo laparoscopic lower abdominal and pelvic surgery were randomly assigned to the remimazolam group(n=44)and the sevoflurane group(n=44).In the remimazolam group,continuous infusion of remimazolam at a rate of 1 mg/(kg·h)was administered for anesthesia maintenance.In contrast,the sevoflurane group inhaled 2％sevoflurane.Heart rate(HR),mean arterial pressure(MAP),peak airway pressure(Peak),plateau airway pressure(Plat),end-tidal CO2(PETCO2),regional cerebral oxygen saturation(rSO2),and optic nerve sheath diameter(ONSD)of both eyes were measured and recorded at the following time points:prior to anesthesia induction(T0),5 minutes after induction(T1),10 minutes(T2),30 minutes(T3),and 60 minutes(T4)after the establishment of pneumo-peritoneum in Trendelenburg position,as well as 30 minutes after deflation in the supine position(T5).Results No significant intergroup differences were detected in HR,MAP,Peak,Plat,or PETCO2 at any time point(P>0.05).In both groups,Peak and Plat values were significantly higher at T2-T4 compared to T1(P<0.05).Regard-ing the ONSD)no intergroup differences were noted at T0 and T1(P>0.05).From T2 to T5,ONSD in both groups increased significantly relative to T0..It gradually rose with the prolongation of pneumoperitoneum and Trendelen-burg positioning and showed a slight decrease at T5(P<0.05).Specifically,at T3 and T4,the remimazolam group exhibited significantly smaller ONSD values than the sevoflurane group(P<0.05).Throughout the study,no inter-group differences in rSO2 were observed(P>0.05).Conclusion In laparoscopic lower abdominal and pelvic surgeries performed in the Trendelenburg position,intravenous anesthesia with remimazolam may be more effective in mitigating the elevation of intracranial pressure compared to sevoflurane inhalation.
