Background::Highly expressed in various human cancers, circular RNA Protein Kinase C Iota (circPRKCI) has been reported to play an important role in cancer development and progression. Herein, we sought to reveal the prognostic and clinical value of circPRKCI expression in diverse human cancers.Methods::We searched the Pubmed, Web of Science, and the Cochrane Library databases from inception until May 16, 2021. The relationship between circPRKCI expression and cancer patients’ survival, including overall survival (OS) and disease-free survival (DFS), was assessed by pooled hazard ratios (HR) with corresponding 95% confidence interval (CI). The correlation between circPRKCI expression and clinical outcomes was evaluated using odds ratios (OR) with corresponding 95% CI. The data were analyzed by STATA software (version 12.0) or Review Manager (RevMan 5.3).Results::A total of 15 studies with 1109 patients were incorporated into our meta-analysis. The results demonstrated that high circPRKCI expression was significantly related to poor OS (HR = 1.96, 95% CI: 1.61, 2.39, P <0.001) when compared with low circPRKCI expression in diverse human cancers. However, elevated circPRKCI expression was not associated with DFS (HR = 1.34, 95% CI: 0.93, 1.95, P = 0.121). Furthermore, the patient with a higher circPRKCI expression was prone to have a larger tumor size, advanced clinical stage, and lymph node metastasis, but it was not significantly correlated with age, gender, and distant metastasis. Conclusion::Elevated circPRKCI expression was correlated with worse OS and unfavorable clinical features, suggesting a novel prognostic and predictive role of circPRKCI in diverse human cancers.

Background/Aims: To evaluate the causal correlation between complement components and non-viral liver diseases and their potential use as druggable targets. Methods: We conducted Mendelian randomization (MR) to assess the causal role of circulating complements in the risk of non-viral liver diseases. A complement-centric protein interaction network was constructed to explore biological functions and identify potential therapeutic options. Results: In the MR analysis, genetically predicted levels of complement C1q C chain (C1QC) were positively associated with the risk of autoimmune hepatitis (odds ratio 1.125, 95% confidence interval 1.018–1.244), while complement factor H-related protein 5 (CFHR5) was positively associated with the risk of primary sclerosing cholangitis (PSC;1.193, 1.048– 1.357). On the other hand, CFHR1 (0.621, 0.497–0.776) and CFHR2 (0.824, 0.703–0.965) were inversely associated with the risk of alcohol-related cirrhosis. There were also significant inverse associations between C8 gamma chain (C8G) and PSC (0.832, 0.707–0.979), as well as the risk of metabolic dysfunction-associated steatotic liver disease (1.167, 1.036–1.314). Additionally, C1S (0.111, 0.018–0.672), C7 (1.631, 1.190–2.236), and CFHR2 (1.279, 1.059–1.546) were significantly associated with the risk of hepatocellular carcinoma. Proteins from the complement regulatory networks and various liver diseaserelated proteins share common biological processes. Furthermore, potential therapeutic drugs for various liver diseases were identified through drug repurposing based on the complement regulatory network. Conclusions Our study suggests that certain complement components, including C1S, C1QC, CFHR1, CFHR2, CFHR5, C7, and C8G, might play a role in non-viral liver diseases and could be potential targets for drug development.

Objective:To analyze the safety and efficacy of ultrasound-guided needle-perc assisted retrograde intrarenal surgery (RIRS) in the treatment of small but complex renal calculi, and summarize our clinical experience.Methods:The clinical data of 36 patients with small but complicated renal stones treated by ultrasound-guided needle-perc assisted RIRS in Beijing Tsinghua Changgung Hospital from January 2020 to April 2022, were retrospectively analyzed. There were 25 males and 11 females. The average age was (54.7±6.1) years, and the body mass index (BMI) was (26.3±3.1) kg/m 2. The maximum diameter of the calculi was (1.8±0.7) cm. There were 28 patients without renal hydronephrosis before operation, 8 patients with mild to moderate renal hydronephrosis, 4 patients with caliceal diverticular stones, 32 patients with lower pole stones, 10 patients with ureteral stones, 6 patients with previous surgical history of ipsilateral kidney stones, and 3 patients with stones in the solitary kidneys. Patients were placed in oblique supine lithotomy position or prone split leg position (female). For lower pole stones or diverticular stones that were difficult to be handled by flexible ureteroscope, the needle-perc was used to puncture the stones in target calyx under ultrasound guidance. Holmium laser was then used to pulverize or fragment the calculi, and the flexible ureteroscope was used to remove or further pulverize the stone fragments. Perioperative indexes and postoperative complications were recorded, and stone-free rate was analyzed. Results:All 36 cases were successfully operated. The median operation time was 61.5(59.0, 66.8)min, with a median decrease in hemoglobin on the first postoperative day of 1.6(0.8, 2.0)g/ L, a median postoperative hospital stay of 1.5(1.0, 2.0)days, and a median needle-perc tract of 1(1, 2). The complications were recorded in 4 patients (11.1%), all of which were Clavien-Dindo grade I, including postoperative fever in 2 patients and analgesic use in 2 patients. The primary stone-free rate was 83.3% (30/36). The 6 patients with residual stones were treated by external physical vibration lithecbole on the 3rd to 7th day after surgery. After 1 month follow-up, residual stone expulsion were seen in 3 patients. Three patients with residual stones were followed up regularly. The final stone-free rate was 91.7% (33/36).Conclusions:Ultrasound-guided needle-per assisted RIRS is safe and effective in the treatment of small but complex renal calculi, with high postoperative stone free rate and low complication rate.

Objective:Super-enhancer-associated genes may be closely related to the progression of osteosarcoma,curcumin exhibits a certain inhibitory effect on tumors such as osteosarcoma.This study aims to investigate the effects of curcumin on osteosarcoma in vitro and in vivo,and to determine whether curcumin can inhibit the progression of osteosarcoma by suppressing the expression of super-enhancer-associated genes LIM and senescent cell antigen-like-containing domain 1(LIMS1),secreted protein acidic and rich in cysteine(SPARC),and sterile alpha motif domain containing 4A(SAMD4A). Methods:Human osteosarcoma cell lines(MG63 cells or U2OS cells)were treated with 5 to 50 μmol/L curcumin for 24,48,and 72 hours,followed by the methyl thiazolyl tetrazolium(MTT)assay to detect cell viability.Cells were incubated with dimethyl sulfoxide(DMSO)or curcumin(2.5,5.0 μmol/L)for 7 days,and a colony formation assay was used to measure in vitro cell proliferation.After treatment with DMSO or curcumin(10,15 μmol/L),a scratch healing assay and a transwell migration assay were performed to evaluate cell migration ability.Real-time reverse transcription polymerase chain reaction(real-time RT-PCR)and Western blotting were used to detect mRNA and protein expression levels of LIMS1,SPARC,and SAMD4A in the cells.An osteosarcoma-bearing nude mouse model was established,and curcumin was administered via gavage for 14 days to assess the impact of curcumin on tumor volume and weight in vivo.Real-time RT-PCR was used to measure mRNA expression levels of LIMS1,SPARC,and SAMD4A in the cancer and adjacent tissues from 12 osteosarcoma patients. Results:After treating cells with different concentrations of curcumin for 24,48,and 72 hours,cell viability were all significantly decreased.Compared with the DMSO group,the colony formation rates in the 2.5 μmol/L and 5.0 μmol/L curcumin groups significantly declined(both P＜0.01).The scratch healing assay showed that,compared with the DMSO group,the migration rates of cells in the 10 μmol/L and 15 μmol/L curcumin groups were significantly reduced.The exception was the 10 μmol/L curcumin group at 24 h,where the migration rate of U2OS cells did not show a statistically significant difference(P＞0.05),while all other differences were statistically significant(P＜0.01 or P＜0.001).The transwell migration assay results showed that the number of migrating cells in the 10 μmol/L and 15 μmol/L curcumin groups was significantly lower than that in the DMSO group(both P＜0.001).In the in vivo tumor-bearing mouse experiment,the curcumin group showed a reduction in tumor mass(P＜0.01)and a significant reduction in tumor volume(P＜0.001)compared with the control group.Compared with the DMSO group,the mRNA expression levels of LIMS1,SPARC,and SAMD4A in the 10 μmol/L and 15 μmol/L curcumin groups were significantly down-regulated(all P＜0.05).Additionally,the protein expression level of LIMS1 in U2OS cells in the 10 μmol/L curcumin group was significantly lower than that in the DMSO group(P＜0.05).Compared with adjacent tissues,the mRNA expression level of SPARC in osteosarcoma tissues was significantly increased(P＜0.00l),while the mRNA expression levels of LIMS1 and SAMD4A did not show statistically significant differences(both P＞0.05). Conclusion:Curcumin inhibits the proliferation and migration of osteosarcoma both in vitro and in vivo,which may be associated with the inactivation of super-enhancer-associated gene LIMS1.
