Objective : To investigate the effects of resveratrol(Res) on fibroblast-like synoviocytes(FLS) in patients with rheumatoid arthritis(RA), and to explore the possible mechanism of Res inhibiting the release of inflammatory factors from FLS. Methods : FLS from RA patients were culturedin vitroand treated with different concentrations of Res(0, 20, 40, 80, 160, 320 μmol/L). The viability of FLS cells was detected by CCK-8 assay after 12 and 24 h. The contents of inflammatory factor interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) in cell supernatant were detected by ELISA. The expression levels of cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS) and stimulator of interferon gene(STING) were measured by Western blot; After lentivirus infection with FLS caused the cells to overexpress cGAS, the cells were divided into Control group(blank control), cGAS group(cGAS overexpression), Res+cGAS group(Res 160 μmol/L+cGAS overexpression) and Res group(Res 160 μmol/L). The expression level of STING protein in cells of each group was determined by Western blot, the viability of FLS cells in each group was detected by CCK-8, and the contents of inflammatory factor IL-6 and TNF-α in the supernatant of cells of each group were detected by ELISA method. Results : The results of CCK-8 experiment showed that under 40, 80, 160 μmol/L Res treatment, FLS viability decreased significantly after 24 h compared with blank control group(P<0.01). ELISA results showed that the contents of IL-6 and TNF-α in cell supernatant were also significantly decreased after treatment with Res of 40, 80 and 160 μmol/L(P<0.01). Meanwhile, Western blot results showed that Res could significantly decrease the protein expression levels of STING and cGAS in FLS cells after treatment of 40, 80 and 160 μmol/L(P<0.05,P<0.01). Compared with the Control group, the expression level of STING protein in FLS increased after overexpression of cGAS(P<0.05); compared with the Res group, the content of inflammatory factors in the supernatant of FLS and the expression level of STING protein in FLS significantly increased after overexpression of cGAS(P<0.01,P<0.05). Conclusion The appropriate concentration of Res can inhibit the release of inflammatory cytokines in FLS cells, which may be related to the blocking of cGAS-STING signaling pathway.

Breast cancer (BC) is one of the most prevalent malignant tumors affecting women worldwide, with its incidence rate continuously increasing. As a result, treatment strategies for this disease have received considerable attention. Research has highlighted the crucial role of the Hedgehog (Hh) signaling pathway in the initiation and progression of BC, particularly in promoting tumor growth and metastasis. Therefore, molecular targets within this pathway represent promising opportunities for the development of novel BC therapies. This study aims to elucidate the therapeutic mechanisms by which natural compounds modulate the Hh signaling pathway in BC. By conducting a comprehensive review of various natural compounds, including polyphenols, terpenes, and alkaloids, we reveal both common and unique regulatory mechanisms that influence this pathway. This investigation represents the first comprehensive analysis of five distinct mechanisms through which natural compounds modulate key molecules within the Hh pathway and their impact on the aggressive behaviors of BC. Furthermore, by exploring the structure-activity relationships between these compounds and their molecular targets, we shed light on the specific structural features that enable natural compounds to interact with various components of the Hh pathway. These novel insights contribute to advancing the development and clinical application of natural compound-based therapeutics. Our thorough review not only lays the groundwork for exploring innovative BC treatments but also opens new avenues for leveraging natural compounds in cancer therapy.

Objective To analyze the relationship between expression levels of long non-coding RNA(LncRNA)LINC00342 and microRNA-203a-3p(miR-203a-3p)in colorectal cancer tissue and the prognosis of patients within 5 years after surgery.Methods Samples of colorectal cancer tissue and paracancer tissue of 133 patients with colorectal cancer were collected.Expression levels of LncRNA LINC00342 and miR-203a-3p were detected by fluorescence quantitative PCR.Survival and death were recorded after 5 years of follow-up.The LncRNA LINC00342 and miR-203a-3p expressions and clinicopathological parameters in patients under different conditions were compared.The correlation between expressions of LncRNA LINC00342 and miR-203a-3p in colorectal cancer tissue was analyzed,and their predictive value for the prognosis was also analyzed.Results The expression level of LncRNA LINC00342 was higher in colorectal cancer tissue than that in paracancer tissue,and the expression level of miR-203a-3p was lower in colorectal cancer tissue than that in paracancer tissue(P＜0.05).The expression levels of LncRNA LINC00342 and miR-203a-3p in colorectal cancer tissue were negatively correlated(P＜0.05).The proportion of patients with low tumor differentiation,TNM stage Ⅲ and lymph node metastasis were higher in the LncRNA LINC00342 high expression group and the miR-203a-3p low expression group than those in the LncRNA LINC00342 low expression group and the miR-203a-3p high expression group,respectively(P＜0.05).The 5-year overall survival rate after operation was lower in the LncRNA LINC00342 high expression group and the miR-203a-3p low expression group(P＜0.05).The proportion of patients with low tumor differentiation,TNM stage Ⅲ,lymph node metastasis,and higher expression level of LncRNA LINC00342 were higher in colorectal cancer tissue of the death group than those in the survival group,and the expression level of miR-203a-3p was lower than that in the survival group(P＜0.05).Low tumor differentiation,TNM stage Ⅲ,lymph node metastasis,high expression of LncRNA LINC00342 and low expression of miR-203a-3p were independent risk factors for death within 5 years after colorectal cancer surgery(P＜0.05).The combined predictive value of LncRNA LINC00342 and miR-203a-3p for prognosis was greater than that of individual prediction.Conclusion LncRNA LINC00342 is higher expressed and miR-203a-3p is lower expressed in colorectal cancer tissue,and the combined detection of the two is expected to become a clinical evaluation indicator for predicting postoperative survival.

Objective To evaluate the application value of artificial intelligence mixed reality(AI-MR)technology in the planning of ultrasound-guided percutaneous nephrolithotomy(PCNL)for special types of complex upper urinary stones.Methods The prospective single-center,single-arm clinical study involved 15 patients with complex upper urinary stones undergoing ultrasound-guided PCNL during Aug.2022 and May 2023,including 9 male and 6 female,3 cases of pelvic ectopic kidney stones,5 cases of horseshoe kidney stones,3 cases of renal stones combined with spinal deformity,and 4 cases of transplant kidney stones.Based on preoperative computed tomography urography(CTU)data,digital three-dimensional reconstruction was performed,and AI-MR was used to project surgery-related three-dimensional images in real space to obtain"perspective"information of the surgical area.This facilitated preoperative design and planning,including target calyx,number of channels,and auxiliary measures.The compliance of target calyx and number of channels,stone clearance rate,total operation time,time required to establish the percutaneous renal channel,decrease in hemoglobin level,surgical complications,and postoperative hospital stay were analyzed.Results All 15 patients underwent preoperative planning using AI-MR and successfully completed one-stage ultrasound-guided PCNL.Based on the preoperative planning,we utilized S-PCNL alone or combined with Needle-perc or antegrade/retrograde FURS/RIRS.Among all patients,4 underwent single-channel S-PCNL,3 multi-channel S-PCNL,and 8 S-PCNL combined with Needle-perc or FURS.The compliance of target calyx and number of channels was 86.7％,the one-stage stone clearance rate was 80.0％,the average time for establishing the channel was(2.3±0.3)minutes,the average total operation time was(61.5±12.2)minutes,the mean decrease in hemoglobin level was(9.6±1.2)g/L,and the average postoperative hospital stay was(4.6±0.5)days.There were no Clavien-Dindo grade ≥ Ⅱ complications,such as blood transfusion,organ injury,or urosepsis.Conclusion Before surgery,AI-MR can be used to quantitatively analyze imaging data for patients with special types of complex upper urinary stones,which can achieve three-dimensional fluoroscopy effects,formulate surgical plans,optimize puncture paths,effectively avoid the risk of damage to surrounding organs,reduce complications,shorten treatment cycle and improve the first-stage stone clearance rate.

Objective:To retrospectively analyze and summarize the clinical experience and therapeutic effect of anterograde Needle-perc combined with RIRS, namely N+ R (Needle perc + RIRS) technique in the treatment of complex calyceal diverticular stone.Methods:Retrospective analysis of 23 cases of complex renal caliceal diverticulum stones admitted to our hospital from January 2020 to December 2022. The complex factors mainly include the invisible cervical orifice of diverticulum, large stone volume, and special anatomical location, which makes single RIRS or PCNL treatment difficult or unsuccessful. There were 14 males and 9 females with an average age of (42.3±6.1) years. Three cases were upper calyceal diverticular stone, average size was (0.9±0.2)cm. Nine patients had diverticular stone in the middle posterior calyx, and the average size was (1.2±0.3)cm. The average size of four diverticular stone was (1.8±0.2)cm in the anterior middle calyx. Seven patients had diverticular stone with an average size of (1.3±0.1)cm in lower calyx. Among them, 12 patients underwent RIRS which were difficult or stone undiscovered, and 3 patients underwent PCNL and the operation was terminated due to failure of channel establishment. In our center, oblique supine lithotomy position (male) or prone split-leg position (female) was adopted, and the combined treatment of Needle-perc and RIRS was performed. Needle-perc puncture was completed under the guidance of full ultrasound. During the operation, methylene blue reagent or mutual guidance of two endoscopes was used to find the diverticulum neck and expand the outlet with holmium laser incision. Depending on the size and location of the stones, a single Needle-perc laser lithotripsy combined with stone removal in flexible ureteroscope was used, or dual lasers were be used simultaneously for stone removal under double endoscopes. The first stage stone free rate, operation time, hemoglobin decrease, complications, postoperative hospital stay and other conditions were analyzed.Results:All the 23 operations were completed successfully. The stone free rate within 48 hours and one month after surgery was 78.2% and 100.0% respectively. The average operation time was (61.5±12.2)min. The mean postoperative hospital stay was (2.8±0.6) days. The mean decrease of hemoglobin was (3.6±0.4)g/L. Three patients had fever and one patient had renal subcapsular effusion. After anti-inflammatory and symptomatic treatment, the patient was discharged. There was no incidence of Clavien-Dindo≥Ⅱcomplications such as blood transfusion, abdominal organ injury or urosepsis.Conclusions:Treatment of complex renal caliceal diverticulum stones using N+ R technique of anterograde needle-perc combined with RIRS can effectively improve the success rate of first-stage surgery. Overall, it is safe, efficient and feasible with the advantages of high stone free rate, lower damage, and few postoperative complications.

Objective: To analyze the spatial temporal distribution characteristics of tuberculosis among high school students at county levels in Gansu Province from 2018 to 2022,so as to provide a scientific basis for tuberculosis prevention and control in schools. Methods: Tuberculosis data from high school students in counties (districts) reported in Gansu Province from 2018 to 2022 was collected from the Tuberculosis Information Management System and Infectious Disease Information Reporting System of the Chinese Disease Prevention and Control Information Management System. Demographic data of high school students in counties (districts) came from the General Management System of the Chinese Disease Prevention and Control Information Management System, and the spatial clustering of the reported incidence rate of pulmonary tuberculosis among high school students in Gansu Province in the past five years was analyzed using the methods of global spatial autocorrelation (Moran s I) and local indicators of spatial audocorrelation(LISA). Results: A total of 41 885 pulmonary tuberculosis cases were reported in various counties of Gansu Province From 2018 to 2022, with an average reported incidence rate of 32.81/100 000. During the same period, 1 170 high school students cases were reported, with an average reported incidence rate of 13.72/100 000. With the exception of 2020, the reported incidence rate of pulmonary tuberculosis among high school students was non random distribution in other 4 years, showed a moderate intensity of spatial clustering. From 2018 to 2022, most counties in Gansu Province reported that the incidence rate of pulmonary tuberculosis among high school students was 10.00/100 000 or below, the counties with reported incidence rate >40.00/100 000 were mainly distributed in Luqu County, Maqu County, Diebu County, Hezuo City, Xiahe County of Gannan Prefecture, Gangu County and Wushan County of Tianshui Prefecture, Wenxian County and Kangxian County of Longnan Prefecture, Huachi County of Pingliang Prefecture, Huanxian County of Qingyang Prefecture. The number of counties where the reported incidence rate of tuberculosis among high school students more than 30.00/100 000 gradually decreased from 2018 to 2022. In the past five years, the reported incidence rate of tuberculosis among high school students in all counties of Gannan Prefecture remained above 40.00/ 100 000 . The LISA analysis results showed that the high incidence areas were mainly concentrated in Gannan Prefecture. Conclusions The epidemic situation of pulmonary tuberculosis among high school students in Gansu province from 2018 to 2022 is still a serious condition, showing the characteristics of unbalanced regional distribution. The reported incidence rate shows a strong spatial clustering, and the hot spots are concentrated in the counties (districts) of Gannan prefecture in Gansu Province.

The incidence and recurrence rates of urinary stone diseases have remained high recently, and stone analysis is of great significance for further understanding of the pathophysiological processes of urinary stones and to develop effective prevention strategies and precise treatment. Imaging evaluation is the main method of preoperative stone analysis, and dual-energy CT has shown its potential in identifying common main components of stones. The emergence of photon counting spectral CT is expected to achieve accurate analysis of stone components at the pixel level. The intraoperative stone analysis mainly relies on the automatic recognition of endoscopic images, and using machine learning algorithms can more reliably predict common stone composition. It is of great significance for stone analysis and assessment of metabolic causes by introducing morpho-constitutional classification (MCC)and observing and describing the papillary renal lesions during operation. This article reviews the progress of preoperative and intraoperative stone analysis, in order to improve clinicians' understanding of the importance of stone analysis, and provide a direction for further clinical research.

Objective:To retrospectively summarize disease characteristics and the clinical experience of minimally invasive endoscopy in the treatment of upper urinary tract obstruction caused by ureteropelvic encrusted inflammatory disease.Methods:Three patients with bilateral ureteropelvic encrusted inflammatory disease admitted to our hospital from March 2018 to July 2021 were involved. Case 1, male, 45 years old, admitted due to bilateral hydronephrosis for 5 months. The preoperative diagnosis were bilateral ureteropelvic stones (encrustation), right ureteral atresia, left ureteral stenosis, and systemic vasculitis. Left double J tube insertion and right nephrostomy were performed in another hospital. We conducted antegrade percutaneous nephroscopy combined with retrograde ureteroscopy surgery and assisted balloon dilation to treat bilateral lesions stage by stage. Case 2, Male, 12 years old, admitted due to bilateral abdominal pain for 6 weeks. The preoperative diagnosis were bilateral ureteral stones, bilateral hydronephrosis, and dermatomyositis. After the failure of double J tube insertion in another hospital, double nephrostomy was performed instead. We performed left percutaneous nephroscopy and right percutaneous nephroscopy combined with ureteroscopy for the treatment of bilateral lesions. Case 3, female, 32 years old, was admitted because of pain in the left lower back and abdomen for over 6 months. The preoperative diagnosis were bilateral ureteral stones, bilateral ureteral stenosis, and dermatomyositis. She underwent three times of ESWL and once URS before. We performed ureteroscopic surgery for bilateral lesions. During the surgery, various degrees of crusting in the renal pelvis or ureter were observed in all 3 cases, and the lesions were removed using pneumatic lithotripsy combined with forceps or baskets. After surgery, oral antibiotics were continuously used for 1-3 months. The efficacy and prognosis were evaluated based on the follow-up of urine, imaging, and endoscopic examinations at 3, 6, and 12 months after surgery.Results:All 3 surgeries were successfully completed. At 3, 6, and 12 months after surgery, follow-up CT showed no crusting in the left ureter, and endoscopy showed good mucosal wound healing and unobstructed lumen in case 1. There were still some crusting lesions and lumen stenosis in the right renal pelvis, and the right ureter reconstruction surgery was ultimately performed. There were no crusting on both sides and the urinary tract was unobstructed after 3, 6, and 12 months of follow-up in case 2 and case 3. Postoperative pathological examination showed chronic inflammation of urothelial mucosal tissue, small pieces of proliferative fibrous tissue with peripheral calcification. Calcification layer composition analysis showed magnesium ammonium phosphate and carbonate apatite. No related complications occurred in case 2 and case 3.Conclusions:Urothelial crusted inflammatory disease is rare clinically, and the diagnosis and treatment strategies are rarely reported domestically and internationally. Preoperative imaging examination, intraoperative findings and postoperative pathology or calcification composition analysis are of instruction for the diagnosis and treatment of this disease. Minimally invasive endoscopy treatment for upper urinary tract obstruction caused by ureteropelvic encrusted inflammatory disease has a good effect. Long-term efficacy and other adjuvant treatment need long-term follow-up and clinical practice.

Objective:To study the incidence and risk factors of central vein stenosis (CVS) in chronic kidney disease (CKD) patients who received arteriovenous fistula (AVF) creation for the first time, as well as effects of CVS on patency of ipsilateral AVF.Methods:It was a retrospective study. The CKD patients who received AVF creation for the first time in the First Affiliated Hospital of Zhengzhou University from January 2019 to August 2020, with central vein digital subtraction angiography (DSA) results prior to angioplasty were selected as the study subjects. The differences of incidence of CVS in CKD patients with/without a history of cervical catheterization and primary patency rates of AVF between CVS and non-CVS groups were compared. Logistic regression analysis method was applied to analyze the influencing factors of CVS in CKD patients. Kaplan-Meier method was used to analyze the primary patency rate of AVF. Cox regression analysis method was used to analyze the effect of CVS on the primary patency of ipsilateral AVF.Results:A total of 283 CKD patients aged (50.45±14.76) years were enrolled in the study, including 165 males (58.3%). The dialysis age was 0.5 (0, 7.0) months. There were 55 patients (19.4%) diagnosed with CVS before AVF, including 39 patients with stenosis <50% and 16 patients with stenosis ≥50%. The incidence of CVS in patients with history of right internal jugular vein central venous catheter insertion was significantly higher than that in those without this history [60.5% (26/43) vs. 9.9% (15/151), χ2=51.274, P<0.001]. Multivariate logistic regression analysis results showed that hemodialysis catheters indwelling time ≥3 months elevated the risk of CVS ( OR=4.345, 95% CI 1.540-12.263, P=0.006). A subset of 268 patients who had AVF creation ipsilateral to CVS were analyzed to determine the effects of CVS on patency of AVF. The median follow-up time was 34 months. The primary patency rate of AVF in the moderate to severe CVS group was significantly lower than that in the non-CVS group (5/7 vs. 58/228, χ2=7.720, P=0.005). The primary patency rates of AVF in the subclavian vein stenosis group and superior vena cava stenosis group were significantly lower than those in the brachiocephalic vein stenosis group (4/5 vs. 8/27, χ 2=6.974, P=0.008; 6/8 vs. 8/27, χ 2=6.908, P=0.009, respectively). Moderate to severe CVS and combined diabetes were independent influencing factors of primary patency of AVF ( HR=4.362, 95% CI 1.644-11.574, P=0.003; HR=2.682, 95% CI 1.624-4.431, P<0.001, respectively). Conclusions:The incidence of CVS is higher in CKD patients who establish an arteriovenous fistula for the first time. Hemodialysis catheter indwelling time ≥3 months is an independent risk factor of CVS. The moderate to severe CVS is an independent risk factor of primary patency of AVF.
