Objective To investigate the diversity and composition of gut fungi microbiota in patients with polycystic kidney disease(PKD)and its correlation with clinical indicators.Methods A total of 44 PKD patients,44 patients with non-polycystic chronic kidney disease(NPCKD)and 22 healthy controls(HC)admitted to our hospital from February 2023 to February 2024 were recruited.ITS1 DNA sequencing was applied to analyze the gut fungal composition.Bioinformatics analysis was used to compare the diversity and structural differences of fungi among the 3 groups.Pearson correlation analysis was performed to analyze the relationship between gut fungi and clinical indicators.Results There were no significant differences in baseline characteristics(gender,age,body mass index,etc.)among the 3 groups,but statistical differences were seen in terms of serum indicators(such as serum creatinine,blood urea nitrogen,uric acid,estimated glomerular filtration rate,etc.)(P<0.01).Alpha diversity analysis showed no significant difference was seen between the PKD and HC groups,but the PKD group had significant differences to the NPCKD group(P<0.01).Beta diversity analysis revealed significant differences among the 3 groups and in pairwise comparisons(P=0.001).Fungi composition analysis found that the abundance of Candida was significantly higher in the PKD group than the other 2 groups(P<0.01),while the abundances of Aspergillus and Cladosporium were significantly lower in the PKD group than the HC group(P<0.05).Linear discriminant analysis(LEFSe)indicated that Candida was significantly enriched,while Aspergillus and Cladosporium were significantly reduced in the PKD group.Correlation analysis revealed that the abundance of Cladosporium was negatively correlated with cyst diameter and immunoglobulin light chain Kappa/Lambda ratio in the PKD group(P<0.05),while the abundance of Candida was positively correlated with liver/kidney cyst diameter(P<0.01).Conclusion PKD patients exhibit characteristic changes in gut fungi diversity and composition.The abundances of Cladosporium and Candida are closely associated with clinical indicators of PKD patients.

Objective:To evaluate the efficacy of total laparoscopic surgery vs. open surgery for hilar cholangiocarcinoma. Methods:The clinical data of 45 patients undergoing laparoscopic radical resection of hilar cholangiocarcinoma and 42 patients by open surgery from Mar 2017 to Mar 2021 were retrospectively analyzed.Results:There was no significant difference in demographics, Bismuth classification and excision extension between the two groups (all P>0.05). The laparoscopic surgery used longer time ( t=-1.366, P<0.05). The intraoperative blood loss, number of lymph node dissection and postoperative hospital stay favored laparoscopic method( t=0.043, t=0.026, t=-1.852, P<0.05). R 0 radical resection rate，postoperative complications were also in favor of laparoscopic surgery ( χ2=3.216, χ2=2.566, all P<0.05). There was no significant difference in postoperative pathology and in hospital expenses (all P>0.05). The 1- and 3-year survival rate of the laparoscopic group was superior (all P<0.05). Conclusions:In spite of longer operational time，patients in laparoscopic hilar cholangiocarcinoma radical resection group have shorter postoperative in hospital stay and longer postoperative survival time.

Malignant tumors are a major health problem in current society. With the improvement of people's living standards and the changes in diet structure， the development trend of gastrointestinal tumors in China is gradually similar to that in developed countries. The incidence and mortality of colorectal cancer （CRC） remain high in China. Although targeted therapy and immunotherapy have greatly improved the prognosis of patients in recent years， chemotherapy is still the main means in clinical practice. However， the adverse reactions of chemotherapy often seriously affect the quality of life of patients， and even lead to treatment interruption， thereby affecting the efficacy. Oral Chinese medicine shows unique advantages in enhancing efficiency and reducing toxicity in CRC patients during chemotherapy， but its poor drug experience not only makes it difficult for patients to take it consistently but also affects the popularization of Chinese medicine at this stage. Medicinal and edible herbs （MEHs） are an important part of Chinese medicine and they are mild， delicious， convenient， affordable， nutritious， and safe. Therefore， they may be more suitable for patients with CRC chemotherapy to adhere to treatment. However， their efficacy is often criticized by clinical practitioners. They are only used in the food and health products industry， and their role as Chinese medicines has not been fully utilized. This paper summarized the common traditional Chinese medicine （TCM） syndromes and treatment methods during CRC chemotherapy， sorted out the nature， flavor， meridian tropism， and efficacy of MEHs， and reviewed the modern pharmacological research results of MEHs by the method of literature statistics. This study finds that the nature， flavor， meridian tropism， and efficacy of MEHs are in good agreement with the common TCM syndromes and treatment methods during CRC chemotherapy. Moreover， many MEHs have the effects of resisting CRC and alleviating the adverse reactions of chemotherapy. Furthermore， the effectiveness and superior efficacy of MEHs in CRC chemotherapy are initially demonstrated from the theoretical level， but high-quality clinical evidence is still needed to support it. The present study discussed the efficiency-enhancing and toxicity-reducing effects and application advantages of MEHs in CRC patients during chemotherapy to provide references for the clinical promotion of MEHs.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To investigate the feasibility of CT hepatic arteriography(CTHA) guided percutaneous radiofrequency ablation of hepatocellular carcinoma (HCC).Methods:Forty-four patients diagnosed with hepatocellular carcinomas were enrolled in this prospective study from September 2019 to May 2021 in Henan Cancer Hospital. Thirty-three out of the 44 patients were treatment naive, 8 cases recurred after radiofrequency ablation, and the other 3 patients recurred after surgery. The mean size of HCC nodules was 5-44(17±8)mm measured on enhanced MRI images. Each patient was implanted a 5-French Cobra catheter or a 5-French RH angiographic catheter, then was catheterized into common hepatic artery or proper hepatic artery, under DSA monitoring via right femoral artery. Then the patient was transferred to CT operation room. Percutaneous radiofrequency ablation was performed by CTHA guidance using contrast agent injected via the catheter indwelled in hepatic artery. The endpoint of a complete ablation was a non-enhancing ablation necrosis zone in the target tumor and the target tumor margin at least 5 mm on CTHA. At the end of the procedure, the probe was retracted using tract ablation, and the arterial catheter and sheath were removed. The number of HCC lesions showed on the enhanced MRI and CTHA imaging were compared using Wilcoxon rank-sum test. The technical success rate and volume of contrast agent used during the CTHA ablation procedures were summarized.Results:Additional tumors were founded in 13 out of the 44 patients during the CT hepatic arteriography compared with enhanced MRI. The tumors founded by enhanced MRI and CTHA were 64 and 91 respectively, with statistical significance ( Z=-3.24, P=0.001). One patient dropped out of the study after palliative ablation and was transferred to transaterial chemoembolization treatment because the number of lesions showed by CTHA scan was more than 5. The other 43 patients got complete ablation verified by immediate postoperative assessment using CTHA. The technical success rate was 100%. The average volume of contrast agent used in CTHA guided radiofrequency ablation was 30-80(42±14)ml. There was no complications occurred related to the CTHA guided percutaneous radiofrequency ablation procedures. Conclusions:CTHA can demonstrate additional lesions that can not be detected by the enhanced MRI images, which improves the lesion conspicuity and verifies the optimal position of radiofrequency probe. The complete tumor ablation can be verified by CTHA performed immediately after ablation.

Objective:To observe the effects of berberine on procoagulant and fibrinolytic inhibitory factors produced by rat type Ⅱ alveolar epithelial cell (AECⅡ) induced by lipopolysaccharide (LPS).Methods:AECⅡ cells (RLE-6TN cells) were cultured in vitro, and the cells in logarithmic growth phase were collected. The cytotoxicity text of berberine was detected by cell counting kit-8 (CCK-8) to determine the drug concentration range according to inhibition concentration of half cells (IC 50). The RLE-6TN cells were divided into five groups, the cells in blank control group were cultured in DMEM; the cells in LPS group were stimulated with 5 mg/L LPS; and the cells in berberine pretreatment groups were pretreated with 20, 50 and 80 μmol/L berberine for 1 hour, and then were co-cultured with 5 mg/L LPS. The cells were collected after LPS induced for 24 hours. The protein and mRNA expression levels of tissue factor (TF), tissue factor pathway inhibitor (TFPI) and plasminogen activator inhibitor-1 (PAI-1) in the cells were detected by Western blotting and real-time fluorescence quantification reverse transcription-polymerase chain reaction (RT-qPCR). The levels of activated protein C (APC), precollagen Ⅲ peptide (PⅢP), thrombin-antithrombin complex (TAT) and antithrombin Ⅲ (ATⅢ) in the cell supernatant were measured by enzyme linked immunosorbent assay (ELISA). Results:According to the inhibition rate curve, the IC 50 of berberine on RLE-6TN cells was 81.16 μmol/L. Therefore, 20, 50 and 80 μmol/L were selected as the intervention concentration of berberine. Compared with the blank control group, the expression and secretion of procoagulant and fibrinolytic inhibitory factors were abnormal in RLE-6TN cells after LPS induced for 24 hours. The protein and mRNA expression levels of TF and PAI-1 in the LPS group were significantly increased, but the protein and mRNA expression levels of TFPI were significantly decreased. Meanwhile, the levels of APC and ATⅢ in the cell supernatant were significantly decreased, while the levels of PⅢP and TAT were significantly increased. After pretreatment with berberine, the abnormal expression and secretion of procoagulant and fibrinolytic inhibitory factors induced by LPS were corrected in a dose-dependent manner, especially in 80 μmol/L. Compared with the LPS group, the protein and mRNA expression levels of TF and PAI-1 in the berberine 80 μmol/L group were significantly decreased [TF protein (TF/GAPDH): 0.45±0.02 vs. 0.55±0.03, TF mRNA (2 -ΔΔCt): 0.39±0.08 vs. 1.48±0.11, PAI-1 protein (PAI-1/GAPDH): 0.37±0.02 vs. 0.64±0.04, PAI-1 mRNA (2 -ΔΔCt): 1.14±0.29 vs. 4.18±0.44, all P < 0.01] and those of TFPI were significantly increased [TFPI protein (TFPI/GAPDH): 0.53±0.02 vs. 0.45±0.02, TFPI mRNA (2 -ΔΔCt): 0.94±0.08 vs. 0.40±0.05, both P < 0.01]. Meanwhile, the levels of APC and ATⅢ in the cell supernatant were significantly increased [APC (μg/L): 1 358.5±26.0 vs. 994.2±23.1, ATⅢ (μg/L): 118.0±7.4 vs. 84.4±2.7, both P < 0.01], while those of PⅢP and TAT were significantly decreased [PⅢP (μg/L): 11.2±0.4 vs. 18.6±0.9, TAT (ng/L): 222.1±2.8 vs. 287.6±7.0, both P < 0.01]. Conclusions:Berberine could inhibit the LPS-induced expressions of procoagulant and fibrinolytic inhibitory factors in rat AECⅡ cells and promote the expressions of anticoagulant factors in a dose-dependent manner. Berberine may be a new therapeutic target for alveolar hypercoagulability and fibrinolysis inhibition in acute respiratory distress syndrome (ARDS).

Objective:To determine the effect of andrographolide (AD) on the expression of procoagulant and fibrinolytic inhibitory factors in rat type Ⅱ alveolar epithelial cells (AECⅡ) stimulated by lipopolysaccharide (LPS).Methods:The AECⅡ cells RLE-6TN in the logarithmic growth phase were divided into 5 groups: the normal control (NC) group, the LPS group, and the 6.25, 12.5, and 25 mg/L AD groups (AD 6.25 group, AD 12.5 group, AD 25 group). The NC group was cultured with RPMI 1640 conventional medium. In the LPS group, 5 mg/L LPS was added to the RPMI 1640 conventional medium for stimulation. Cells in the AD groups were treated with 6.25, 12.5, and 25 mg/L AD in advance for 1 hour and then given LPS to stimulate the culture. The cells and cell culture supernatant were collected 24 hours after LPS stimulation. The protein and mRNA expressions of tissue factor (TF), tissue factor pathway inhibitor (TFPI), and plasminogen activator inhibition-1 (PAI-1) in cells were detected by Western blotting and real-time fluorescent quantitative polymerase chain reaction (RT-qPCR). The levels of procollagen Ⅲ peptide (PⅢP), thrombin-antithrombin complex (TAT), antithrombin Ⅲ (AT-Ⅲ) and activated protein C (APC) in the cell supernatant were detected by enzyme linked immunosorbent assay (ELISA).Results:Compared with the NC group, the protein and mRNA expressions of TF and PAI-1 in the LPS group were significantly increased, and the protein and mRNA expressions of TFPI were significantly reduced. At the same time, the levels of PⅢP and TAT in the cell supernatant were significantly increased, the levels of AT-Ⅲ, APC were significantly reduced. Compared with the LPS group, the protein and mRNA expressions of TF and PAI-1 in AD 6.25 group, AD 12.5 group, AD 25 group were significantly reduced [TF/GAPDH: 0.86±0.08, 0.45±0.04, 0.44±0.04 vs. 1.32±0.10, TF mRNA (2 -ΔΔCt): 2.59±0.25, 2.27±0.05, 1.95±0.04 vs. 4.60±0.26, PAI-1/GAPDH: 2.11±0.07, 1.45±0.04, 0.86±0.09 vs. 2.56±0.09, PAI-1 mRNA (2 -ΔΔCt): 3.50±0.22, 2.23±0.29, 1.84±0.09 vs. 6.60±0.27, all P < 0.05], while the protein and mRNA expressions of TFPI were significantly increased [TFPI/GAPDH: 0.78±0.05, 0.81±0.03, 0.84±0.07 vs. 0.36±0.02, TFPI mRNA (2 -ΔΔCt): 0.46±0.09, 0.69±0.07, 0.91±0.08 vs. 0.44±0.06, all P < 0.05]. Also the levels of PⅢP and TAT in the cell supernatant were significantly reduced, and the levels of AT-Ⅲ and APC were significantly increased [PⅢP (μg/L): 13.59±0.23, 12.66±0.23, 10.59±0.30 vs. 15.82±0.29, TAT (ng/L): 211.57±6.41, 205.69±4.04, 200.56±9.85 vs. 288.67±9.84, AT-Ⅲ (μg/L): 102.95±3.86, 123.92±2.63, 128.67±1.67 vs. 92.93±3.36, APC (μg/L): 1 188.95±14.99, 1 366.12±39.93, 1 451.15±29.69 vs. 1 145.55±21.07, all P < 0.05]. With the increase of the dose of AD, the above-mentioned promotion and inhibition effects became more obvious. In the AD 25 group, TF, PAI-1 protein and mRNA expressions decreased, TFPI mRNA expression increased, PⅢP level in the supernatant decreased and AT-Ⅲ, APC levels increased compared with AD 6.25 group, the difference was statistically significant, and the decrease of PAI-1 protein expression and PⅢP level in the supernatant were also statistically significant compared with AD 12.5 group. Conclusions:Andrographolide in the dose range of 6.25-25 mg/L can dose-dependently inhibit the expression and secretion of procoagulant and fibrinolytic inhibitor-related factors in AECⅡ cells RLE-6TN stimulated by LPS, and promote the secretion of anticoagulant factors. 25 mg/L has the most obvious effect.
