Objective To evaluate the safety and effect of one-way barbs line (absorbable sutures v - locTM180) in primary suturing of laparoscopic choledocholithotomy. Methods From July 2014 to June 2015, clinical data of 86 cases performed primary suturing in laparoscopic choledocholithotomy by the same performer were retrospectively analyzed. The patients were divided into three groups, One-way barbs line continuous full-thickness suture group (A group), ordinary absorption line continuous full-thickness suture group (B group) and ordinary absorption line discontinuous full-thickness suture group (C group). The bile duct suture needed time, intraoperative blood loss, postoperative eating time, postoperative hospital stay and postoperative bile fistula were compared. Results All the 86 cases underwent successful operation without T tube, and none of them received alternative open operation. Compared with group B and C, time needed for bile duct suturing in A group have statistical significance. There was no significant difference in the intraoperative blood loss, postoperative eating time, postoperative hospital stay between the three groups (P > 0.05). The incidence of postoperative bile fistula in A group were none. The incidence of postoperative bile fistula in B group was 1 case, the incidence of postoperative bile fistula in C group was 2 cases.Conclusions The method of one-way barbs line continuous full-thickness suture were simple and secure in primary suturing of laparoscopic choledocholithotomy.

Gliomas are one of the most common types of brain cancers. Numerous efforts have been devoted to studying the mechanisms of glioma genesis and identifying biomarkers for diagnosis and treatment. To help further investigations, we present a comprehensive database named GliomaDB. GliomaDB includes 21,086 samples from 4303 patients and integrates genomic, transcriptomic, epigenomic, clinical, and gene-drug association data regarding glioblastoma multiforme (GBM) and low-grade glioma (LGG) from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), the Chinese Glioma Genome Atlas (CGGA), the Memorial Sloan Kettering Cancer Center Integrated Mutation Profiling of Actionable Cancer Targets (MSK-IMPACT), the US Food and Drug Administration (FDA), and PharmGKB. GliomaDB offers a user-friendly interface for two main types of functionalities. The first comprises queries of (i) somatic mutations, (ii) gene expression, (iii) microRNA (miRNA) expression, and (iv) DNA methylation. In addition, queries can be executed at the gene, region, and base level. Second, GliomaDB allows users to perform survival analysis, coexpression network visualization, multi-omics data visualization, and targeted drug recommendations based on personalized variations. GliomaDB bridges the gap between glioma genomics big data and the delivery of integrated information for end users, thus enabling both researchers and clinicians to effectively use publicly available data and empowering the progression of precision medicine in glioma. GliomaDB is freely accessible at http://bigd.big.ac.cn/gliomaDB.

The challenging clinical outcomes associated with advanced cervical cancer underscore the need for a novel therapeutic approach. Monensin, a polyether antibiotic, has recently emerged as a promising candidate with anti-cancer properties. In line with these ongoing efforts, our study presents compelling evidence of monensin's potent efficacy in cervical cancer. Monensin exerts a pronounced inhibitory impact on proliferation and anchorage-independent growth. Additionally, monensin significantly inhibited cervical cancer growth in vivo without causing any discernible toxicity in mice. Mechanism studies show that monensin's anti-cervical cancer activity can be attributed to its capacity to inhibit the Wnt/β-catenin pathway, rather than inducing oxidative stress. Monensin effectively reduces both the levels and activity of β-catenin, and we identify Akt, rather than CK1, as the key player involved in monensin-mediated Wnt/β-catenin inhibition. Rescue studies using Wnt activator and β-catenin-overexpressing cells confirmed that β-catenin inhibition is the mechanism of monensin’s action. As expected, cervical cancer cells exhibiting heightened Wnt/β-catenin activity display increased sensitivity to monensin treatment. In conclusion, our findings provide pre-clinical evidence that supports further exploration of monensin's potential for repurposing in cervical cancer therapy, particularly for patients exhibiting aberrant Wnt/β-catenin activation.

Objective:
To summarize the clinical manifestation and molecular characteristics of COQ6 mutation induced nephrotic syndrome, and to evaluate efficacy of CoQ10 therapy.
Method:
Clinical data of the case with infantile nephrotic syndrome was summarized, including clinical manifestations, laboratory findings and family investigation. The patient received CoQ10 30 mg/(kg·d) therapy. Urine protein/creatinine ratio, serum albumin and creatinine were detected to assess the efficacy of the therapy.
Result:
(1) The 10 months old boy was presented with nephrotic level proteinuria and hypoalbuminemia. Extra-renal manifestations included cardiovascular abnormality, motor and mental retardation and unilateral ptosis. The patient had no consanguinity. A novel homozygous p. R360W mutation in COQ6 gene was identified and confirmed by next-generation sequencing and Sanger sequencing, respectively. Family analysis showed that homozygous p. R360W mutation in COQ6 gene was inherited from his parents. Missense p. R360W mutation was damaging by prediction online PolyPhen and SIFT software. After 2 months of CoQ10 complementary therapy, the patient′s urine protein/creatinine ratio declined from 7.2 to 1.3, and decreased further to 0.01 mg/mg with normal albumin level and renal function within 3 months. Nephropathy remission was maintained and growth retardation improved significantly during the last follow-up. Nevertheless, the patient manifested with sensorineural deafness at the age of 2 years. (2) There were 6 different mutations in coenzyme Q10 biosynthesis monooxygenase 6 (COQ6) in 13 individuals from 7 families by homozygosity mapping in the whole world. Each mutation was linked to early-onset SRNS with sensorineural deafness. Renal biopsy revealed FSGS in 7 cases and DMS in 1 case. Other manifestations included ataxia, seizures, facial dysmorphism, nephrolithiasis and growth retardation. Four patients received CoQ10 supplementation and responded to the treatment.
Conclusion
Renal disease caused by recessive COQ6 gene mutation was nephrotic syndrome. The patient benefited from early CoQ10 complement and reached nephropathy remission.

Objective:
To investigate the clinical and genetic character of Chinese children with the aarF domain containing kinase 4 (ADCK4)-associated glomerulopathy.
Methods:
Applying next generation sequencing to detect possible gene mutation(renal disease associated monogene was pooled as one panel) in 69 children with steroid-resistant nephrotic syndrome (SRNS) or persistent proteinuria of unknown origin. Sanger sequencing was used to confirm the significant mutations found in the children and to validate these mutation sites in their patients. Using online software (PolyPhen2, SIFT, Mutation Taster) to predict whether the detected missense mutations were disease causing or not. Collecting and analyzing clinical data of children with ADCK4-associated glomerulopathy, which included onset age, clinical manifestation, and renal pathology.
Results:
The ADCK4 gene mutation was detected in 8 children with a positive rate of 11.6% (8 out of 69), among which 3 patients carried homozygous c.748G>C mutation, 3 patients carried homologous c.737G>A mutation, 1 patient carried compound heterozygous mutation(c.748G>C and c.737G>A), and 1 patient carried compound heterologous mutation(c.551A>G and c.737G>A). Collectively, there were only 3 mutation sites found in total 8 patients, in which the mutation sites of c.748G>C and c.737G>A had high detection frequency in these 8 patients. These 3 mutation sites were all missense mutation which were predicted to be disease causing by online software and not reported before. The average onset age was 6.5 years (2 years-11.75 years). Four patients presented with SRNS and the other 4 presented with persistent proteinuria. All 8 patients had no extrarenal manifestation, renal biopsy revealed focal segmental glomerulosclerosis (FSGS) in most patients, among which 3 cases had gone to end-stage renal disease (ESRD) at disease onset, and 2 cases progressed to ESRD 2 and 5 years after onset respectively. Seven patients had received glucocorticoid and/or immunosuppressive drug while only one patient getting partial response. All 8 patients were treated with large amount of coenzyme Q10 (15 mg·kg-1·d-1) after definite diagnosis of ADCK4 mutation-some patients had acquired encouraging curative effect.
Conclusions
ADCK4-associated glomerulopathy is not rare especially in the children with SRNS. The onset age is relatively old and the extrarenal manifestation is less common. FSGS is a main pathology type. Patients usually have no response to immunosuppressive therapy, but may benefit from addition of large amount of coenzyme Q10. Some patients may only manifest with insidious proteinuria, causing the early diagnosis to be difficult, which deserves more attention. Three new missense mutations expand disease causing mutation repertoire of ADCK4 gene, among which the two sites of c.748G>C and c.737G>A may be mutation hotspot of ADCK4-associated glomerulopathy in Chinese population, and need further study.
