ObjectiveTo explore the characteristics of traditional Chinese medicine （TCM） syndromes in the patients with concurrent knee osteoarthritis （KOA） and postmenopausal osteoporosis （PMOP） and provide a scientific basis for precise TCM syndrome differentiation， diagnosis， and treatment of such concurrent diseases. MethodsA prospective， multicenter， cross-sectional clinical survey was conducted to analyze the characteristics of TCM syndromes in the patients with concurrent PMOP and KOA. Excel 2021 was used to statistically analyze the general characteristics of the included patients. Continuous variables were reported as x¯±s， and binary variables were reported as percentages. UCINET and Gephi were used to construct a complex "isease-syndrome-symptom" network for in-depth mining. Topological structure indicators， edge connection information between nodes， and weighted adjacency matrices were calculated by UCINET and Python. Gephi was used for complex network visualization. ResultsA total of 157 patients with concurrent PMOP and KOA from 12 TCM hospitals or community health service centers were selected for the collection of TCM syndrome and symptom information. A total of 4 main TCM syndromes were obtained， which were kidney-Yang deficiency （47.13%）， liver-kidney Yin deficiency （36.94%）， spleen-kidney Yang deficiency （8.92%）， and kidney Yin-Yang deficiency （7.01%）. In addition， 10 concurrent syndromes （mainly Qi stagnation and blood stasis， Qi and blood deficiency， spleen Yang deficiency， and cold-dampness） were identified. Based on the results of comprehensive frequency statistics and complex network analysis， as well as TCM theoretical knowledge and relevant guidelines， the general characteristics of concurrent PMOP and KOA and the main TCM syndromes in the dimensions of physical symptoms， pain， tongue and pulse manifestations， and defecation and urination were obtained. ConclusionThe main TCM syndromes in the patients with concurrent PMOP and KOA may be kidney Yang deficiency， liver-kidney Yin deficiency， spleen-kidney Yang deficiency， and kidney Yin-Yang deficiency， among which kidney Yang deficiency and liver-kidney Yin deficiency are the core TCM syndromes.

Pancreatic cancers (PCs) is a common malignant tumor with poor prognosis in the digestive system. Its main treatment methods include surgery, radiotherapy, chemotherapy, and targeted therapy. The early diagnosis rate of hidden onset of PCs is low, and most patients have already lost the opportunity to undergo surgery when diagnosed with PCs. Chemotherapy is still the main treatment for advanced PCs, but the use of chemotherapy drugs in PCs can easily lead to drug resistance. The most significant feature that distinguishes PCs from other tumors is its rich and dense matrix, which not only hinders drug penetration but also impedes the infiltration of immune cells. The above reasons have led to a very low survival rate of PCs patients. Therefore, drug delivery systems are very important in the diagnosis and treatment of PCs. They can improve drug delivery, enhance biological barrier penetration, reduce side effects, and combine multiple treatment methods. Therefore, the treatment prospects of PCs are very broad. Currently, drug delivery systems widely applied in PCs primarily include nanodrug delivery systems, tumor microenvironment-targeted drug delivery system, immunotherapy drug delivery system, gene therapy drug delivery system, and combination therapy drug delivery system that synergize multiple therapeutic modalities. Emerging drug delivery systems (DDSs) have revolutionized PCs treatment by addressing these challenges through multiple mechanisms. Nanoformulations improve drug solubility, prolong circulation time, and reduce systemic toxicity via passive/active targeting. Smart DDSs responsive to PCs-specific stimuli enable extracellular matrix degradation, tumor-associated fibroblasts reprogramming, and vascular normalization to enhance drug accessibility. Last but not least, carrier systems loaded with myeloid-derived suppressor cell inhibitors or T cell activators can reverse immunosuppression and potentiate immunotherapy efficacy. Advanced platforms co-deliver chemotherapeutics with immunomodulators, gene-editing tools, or sonodynamic agents to achieve synergistic antitumor effects. These platforms aim to address critical challenges in PCs treatment, such as enhancing drug bioavailability, overcoming stromal barriers, reprogramming immunosuppressive niches, and achieving multi-mechanistic antitumor effects. This article provides a systematic summary and prospective analysis of the current development status, latest cutting-edge advances, opportunities, and challenges of the above-mentioned drug delivery systems in the field of PCs therapy.

Objective To compare the clinical efficacy of three different therapies,including transjugular intrahepatic portosystemic shunt(TIPS)treatment,endoscopic treatment and medication treatment,combined with transhepatic arterial chemoembolization(TACE)in treating primary liver cancer complicated by portal hypertension and upper gastrointestinal bleeding.Methods A total of 105 patients with primary liver cancer associated with portal hypertension and upper gastrointestinal bleeding,who were admitted to the No.980 Hospital of PLA Joint Logistics Support Forces of China to receive treatment between January 2014 and June 2020,were enrolled in this study.According to the therapeutic scheme,the patients were divided into TIPS+TACE group(TIPS group,n=25),endoscopy+TACE group(endoscopy group,n=30),and medication+TACE group(medication group,n=50).The clinical efficacy,recurrence rate of bleeding,incidence of hepatic encephalopathy,and survival rate were compared between each other among the three groups.Results The differences in the postoperative 6-month,12-month and 24-month recurrence rates of bleeding between each other among the three groups were statistically significant(all P＜0.05).In TIPS group,the portal vein pressure decreased from preoperative(38.47±9.35)mmHg(1 mmHg=0.133 kPa)to postoperative(25.24±5.68)mmHg,the difference was statistically significant(P＜0.05).After treatment,the hemoglobin level in the three groups showed varying degrees of elevation,which in the TIPS group and endoscopy group were better than that in the medication group,the differences were statistically significant(P＜0.05).In all three groups,the differences in the recurrence rate of bleeding between postoperative 6-month value,12-month value and 24-month value were statistically significant(all P＜0.05).The postoperative 6-month,12-month and 24-month recurrence rates of bleeding in the TIPS group were lower than those in the endoscopy group and the medication group,and the differences were statistically significant(P＜0.05).The postoperative 12-month and 24-month recurrence rates of bleeding in the TIPS group were lower than those in the endoscopy group,and the differences were statistically significant(P＜0.05).The postoperative 12-month and 24-month recurrence rates of bleeding in the endoscopy group were lower than those in the medication group(P＜0.05),and the difference in the postoperative 6-month recurrence rate of bleeding between the two groups was not statistically significant(P＞0.05).The postoperative 6-month and 12-month incidences of hepatic encephalopathy in the TIPS group were higher than those in the endoscopy group and the medication group,the differences were statistically significant(P＜0.05),while the differences in the postoperative 6-month and 12-month incidences of hepatic encephalopathy between the endoscopy group and the medication group were not statistically significant(P＞0.05),and the differences in the postoperative 24-month incidence of hepatic encephalopathy between each other among the three groups were not statistically significant(P＞0.05).No statistically significant difference in the 6-month mortality existed between TIPS group and endoscopy group(P＞0.05),and the 6-month mortality of both TIPS group and endoscopy group was remarkably lower than that of the medication group(P＜0.05).The postoperative 12-month mortality and 24-month mortality in TIPS group were lower than those in the endoscopy group and the medication group,and the differences were statistically significant(P＜0.05),but the differences in the postoperative 12-month mortality and 24-month mortality between the endoscopy group and the medication group were not statistically significant(P＞0.05).Conclusion For primary liver cancer associated with portal hypertension and upper gastrointestinal bleeding,TIPS combined with TACE can effectively control tumor progression and prolong survival.(J Intervent Radiol,2024,32:33-37)

Objective To compare the diagnostic value of transvaginal ultrasound(TVS)and thin-section oblique axial T2WI in deep infiltrating endometriosis(DIE)of uterosacral ligaments(USL).Methods Retrospective analysis was conducted on preoperative TVS and MRI images from 74 patients with USL-DIE.The diagnostic efficacy of TVS and thin-section oblique axial T2WI for USL-DIE was evaluated using receiver operating characteristic(ROC)curve based on pathological findings,and area under the curve(AUC),sensitivity,specificity,accuracy,positive predictive value(PPV)and negative predictive value(NPV)were further calculated.The McNemar two-tailed test was used to analyze the difference in diagnostic accuracy between the two methods for USL-DIE.Results The AUCs of TVS and thin-section oblique axial T2WI for diagnosing left and right USL-DIE were 0.721 vs 0.842 and 0.640 vs 0.901,respectively.Thin-section oblique axial T2WI demonstrated higher sensitivity,accuracy,PPV,and NPV compared to TVS in diagnosing USL-DIE.The diagnostic accuracy was found to be statistically different between the two methods(Pleft =0.026,χ2=4.966;Pright<0.001,χ2=16.531).Conclusion Thin-section oblique axial T2WI outperformed TVS in terms of diagnostic value for USL-DIE,providing valuable imaging support for accurate clinical diagnosis.

BACKGROUND:In recent years,the incidence of hyperuricemia caused by purine metabolism disorders has been increasing,which can induce inflammatory responses and lead to renal injury. OBJECTIVE:To explore the role and mechanism of solute carrier family 2 member 12(SLC2A12)in hyperuricemia-related renal injury. METHODS:Renal tubular cells(HK2 cells)were divided into five groups:HK2 group,HK2+uric acid group,HK2+uric acid+NC group,HK2+uric acid+siSLC2A12 group,and HK2+uric acid+siSLC2A12+MK-2206 group.HK2 cells were treated with uric acid and transfected with siRNA SLC2A12,followed by MK-2206 treatment to inhibit AKT expression.Cell proliferation was detected by CCK-8 assay.Apoptosis was detected by TUNEL assay.qRT-PCR and western blot assay were used to detect fibrogenic factors as well as activation of the AKT/FOXO3a pathway.The concentrations of inflammatory cytokines were measured by enzyme-linked immunosorbent assay. RESULTS AND CONCLUSION:(1)Uric acid treatment inhibited cell proliferation and promoted cell apoptosis in the HK2+uric acid group compared with the HK2 group.The proliferative ability of cells in the HK2+uric acid+siSLC2A12 group was further decreased and apoptotic cells were further increased compared with the HK2 group.Compared with the HK2+uric acid+siSLC2A12 group,the HK2+uric acid+siSLC2A12+MK-2206 group showed an increase in cell proliferation and a decrease in apoptotic cells.(2)Compared with the HK2 group,the connective tissue growth factor(CTGF),α-smooth muscle actin(α-SMA)and transforming growth factor beta(TGF-β)expressions increased in the HK2+uric acid group;CTGF,α-SMA and TGF-β expression further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,the CTGF,α-SMA and TGF-β expressions decreased.(3)Compared with the HK2 group,the expression of p-AKT,FOXO3a,and p-FOXO3a elevated in the HK2+uric acid group;the expression of p-AKT further increased,while the expression of FOXO3a and p-FOXO3a decreased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,p-AKT expression decreased;FOXO3a and p-FOXO3a expression increased in the HK2+uric acid+siSLC2A12+MK-2206 group.(4)Compared with the HK2 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels increased in the HK2+uric acid group;interleukin-6,interleukin-1 β,and tumor necrosis factor α levels further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels diminished in the HK2+uric acid+siSLC2A12+MK-2206 group.(5)These findings indicate that SLC2A12 may protect against hyperuricemia-induced renal injury by counteracting uric acid-induced tubular fibrosis and inflammation through activation of the FOXO3a pathway.

ObjectiveTo introduce the basic design， development plan and objectives of a population-based birth cohort in Shanghai， and further present the main data and baseline characteristics of enrolled participants in the cohort， and to provide key information for reproductive health-related studies. MethodsThe Shanghai population-based birth cohort initiated on January 1， 2005， included newborns born in Shanghai every year and their parents， and collected information on reproductive health， reproductive treatment， birth characteristics， growth and development status， as well as the incidence， treatment and death of diseases by employing data linkage technology and investigations. This formed a birth cohort spanning the entire life cycle. ResultsAs of October 2022， a total of 2 978 538 newborns and their parents were included in the cohort. Among them， 2 905 135 （97.54%） were naturally conceived （NC）， and 73 403 （2.46%） were born through assisted reproductive technologies （ART）. The average age of parents was （32.56±4.12） years old for females and （34.62±5.34） years old for males in the ART group， which was higher than （28.02±4.71） years and （30.07±5.54） years for parents in the NC group. Among parents， females and males aged 30 and above accounted for 77.12% and 85.08%， respectively， which were higher than that of parents （35.28% for females and 49.66% for males） in the NC group. Furthermore， the percentage of parents with a college degree or above in the ART group was 73.23% for females and 73.66% for males， which were higher than those in the NC group （49.98% and 50.91%， respectively）. The multiple births rate in the ART group was 33.81%， which was higher than that in the NC group （1.88%）. The incidence of premature birth and low birth weight in the ART group were 24.47% and 19.08%， respectively， which was higher than that in the NC group （5.47% and 3.73%）. ConclusionThe comprehensive collection of reproductive health-related information in the birth cohort in Shanghai can provide essential resources to determine the influence of genetics， environment， reproductive treatment and other related factors on the health of offspring after birth.

ObjectiveTo explore the current status and issues regarding the application of ancient books in clinical practice guidelines and expert consensus of traditional Chinese medicine （TCM） published in China， and to provide methodological recommendations for the incorporation of ancient books in the development of TCM guidelines. MethodsWe searched China National Knowledge Infrastructure （CNKI）， WanFang Data， VIP， SinoMed， PubMed， Embase， as well as six industry websites including China Association of Chinese Medicine， National Group Standards Information Platform， and Chinese Association of the Integration of Traditional and Western Medicine，etc. TCM clinical practice guidelines or expert consensus issued during January 1st， 2017， to November 26th， 2022 were searched. Clinical practice guidelines or expert consensus that explicitly referred to ancient books were included， and the content regarding the searching for ancient books， sources of access to ancient books， methods of evaluating the level of evidence， methods of evaluating the level of recommendation， and methods of evaluating the evidence for the ancient books were analysed. ResultsA total of 1,215 TCM clinical practice guidelines or expert consensus were retrieved， with 442 articles explicitly mentioning the application of ancient books， including 300 （67.87%） clinical practice guidelines and 142 （32.13%） expert consensus. Sixty of the 442 publications explicitly reported that ancient books searching had been conducted （13.57%）； among these 60 publications 27 （45.00%） explicitly reported ancient books searching strategies， and the most frequent method was manual searching with a total of 24 articles （40.00%）. The most popular search source was Chinese Medical Dictionary， a TCM classics database， with a total of 18 articles. 197 articles （44.57%） explicitly reported the evaluation criteria for the level of evidence， of which 141 articles （71.57%） involved the evaluation criteria for the ancient books； 413 articles （93.44%） mentioned ancient books in the recommendations， and only the source of formula name was mentioned in 409 （99.03%） of the publications. ConclusionThe current application of ancient books in TCM clinical practice guidelines and expert consensus is limited， with issues of non-standard searching and evaluation methods. Standar-dization and uniformity are needed in evidence grading and recommendation standards. Future research should clarify the scope and methods of applying ancient book， emphasize their integration with modern research evidence， and enhance their value and quality in the development of TCM clinical practice guidelines.
