ABSTRACT

BACKGROUND: Endoscopic ultrasound-guided pancreatic duct (PD) drainage (EUS-PDD) is being increasingly performed as an alternative method to surgical drainage to achieve PD decompression after failed endoscopic retrograde pancreatography (ERP). However, no directly study has compared EUS-PDD with surgical PD drainage after failed ERP in patients with chronic pancreatitis. METHODS: Consecutive patients who underwent EUS-PDD or longitudinal pancreaticojejunostomy after failed ERP were retrospectively identified from our endoscopy and medical information systems. The primary end point was the Izbicki pain score. The secondary end points were pain relief at the end of follow-up, procedure outcomes, adverse events, readmission, and reintervention. RESULTS: A total of 21 patients (11 EUS-PDD, 10 surgical drainages) were analyzed. There were no significant differences in mean Izbicki pain score (EUS-PDD, 13.6 ± 10.1 vs. surgical drainage 10.7 ± 7.9, p = 0.483) or complete/partial pain relief (60%/30% vs. 70%/30%, p = 0.752) at the end of follow-up of the two groups. The rates of overall adverse events (27.3% vs. 30.0%, p = 0.893) and readmission (63.6% vs. 40.0%, p = 0.290) were similar in the two treatment groups, while patients in EUS-PDD group required more reinterventions (45.5% vs. 0%, p = 0.039) compared with patients in the surgery group. CONCLUSION: EUS-PDD showed comparable pain relief and safety to surgical PD drainage after failed ERP, with a higher rate of reintervention. The selection of EUS-PDD or surgical drainage may be appropriate based on an individualized strategy.

ABSTRACT

BACKGROUND AND AIM: Several meta-analyses have analyzed the technical and clinical success of endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) by using lumen-apposing metal stents (LAMS) in malignant biliary obstruction, but those concerning adverse events (AEs) are scarce. The current systematic review and meta-analysis was conducted to evaluate the AEs after EUS-CDS with LAMS. METHODS: A comprehensive literature search of PubMed, Embase, Scopus, Web of Science, and the Cochrane Library was conducted for studies reporting the outcomes of EUS-CDS with LAMS. The main endpoints were the incidence of overall and specific AEs. Moreover, the stent dysfunction, and reintervention rates were evaluated independently. RESULTS: A total of 21 studies (n = 1438) were included in the final meta-analysis. The pooled rate of technical and clinical success was 93.5% (95% confidence interval [CI]: 91.3-95.1) and 88.0% (95% CI: 83.9-91.1), respectively. After EUS-CDS with LAMS, the pooled incidence of overall AEs was 20.1% (95% CI: 16.0-24.9). The estimated rate of early AEs was 10.6% (95% CI: 7.9-14.2), and late AEs was 11.2% (95% CI: 8.2-15.2). Infection/cholangitis was the commonest AE, with a pooled incidence of 6.1% (95% CI: 3.7-10.1). The estimated incidence of stent dysfunction and reintervention was 10.5% (95% CI: 7.5-14.4), and 12.1% (95% CI: 9.3-15.7), respectively. CONCLUSION: Despite with a high technical and clinical success rate, EUS-CDS with LAMS may be associated with overall AEs and stent dysfunction in one-fifth and one-tenth of cases, respectively. Further efforts are required to optimize its safety and long-term stent patency.

ABSTRACT

Background: To investigate the efficacy of aloe gel in reducing pain and promoting wound healing in postpartum women with nipple trauma. Method: There were 80 postpartum women who took part in this study having developed nipple trauma during breastfeeding in the obstetrics department of a tertiary grade A hospital in Suzhou from January to December 2021. Postpartum women with nipple trauma whose hospital bed numbers ranged between 15 and 33 were included in the test group, whereas those whose hospital bed numbers ranged between 35 and 53 were included in the control group. Both groups received health education and breastfeeding guidance. The control group applied lanolin cream to their nipple trauma, whereas the test group used aloe gel. We used a nipple trauma severity assessment table to determine the severity of nipple trauma in lactating women and a Visual Analogue Scale (VAS) to determine the level of nipple pain and referred to the Traditional Chinese Medicine Standard for Diagnosis and Therapeutic Efficacy for Diseases and Syndromes to determine the healing time of their wounds. Results: The test group scored 3.70 ± 1.24 and 1.65 ± 0.74 points on the VAS on the first and third days following the intervention, whereas the control group scored 4.30 ± 0.94 and 2.23 ± 1.07 points, respectively. It took 3.75 ± 1.08 days and 4.45 ± 1.15 days for the nipple pain to completely disappear in the test group and the control group, respectively. The healing period for nipple trauma was 5.28 ± 1.26 days for the test group and 6.03 ± 1.61 days for the control group. All of the aforementioned distinctions were statistically significant (p < 0.05). Conclusions: Aloe gel can significantly alleviate the pain associated with nipple trauma in lactating women, accelerate wound healing, and reduce the duration of nipple trauma.

ABSTRACT

OBJECTIVE: A comprehensive meta-analysis was performed to evaluate the efficacy and safety of endoscopic ultrasound-guided gastroenterostomy (EUS-GE) for benign and malignant gastric outlet obstruction (GOO). MATERIAL AND METHODS: PubMed, Embase, Web of Science and Cochrane Library were searched to identify relevant studies. The primary outcomes evaluated technical success, clinical success, and adverse events (AEs). RESULTS: Twenty­six studies with 1493 patients were included in this meta-analysis. The pooled rates of technical success, clinical success, and overall AEs of EUS-GE were 94.0%, 89.9%, and 13.1%, respectively. Eight studies were included in the subgroup meta-analysis for comparative evaluation of EUS-GE and surgical gastroenterostomy (SGE), while seven studies were for EUS-GE and enteral stenting (ES). Compared with SGE, the pooled odds ratios (ORs) of technical success, clinical success, and overall AEs of EUS-GE were 0.17 (p = .003), 1.42 (p = .40), and 0.15 (p < .00001), respectively. When compared with ES, the above corresponding pooled ORs were 0.55 (p = .11), 2.64 (p < .0001), and 0.41 (p = .01), respectively. CONCLUSION: Although it is technically challenging, this largest meta-analysis indicates that EUS­GE has comparable and high technical and clinical success rates and hence a very effective minimally invasive procedure for GOO.

ABSTRACT

Aim To explore the effects of Zhishi Xiebai Guizhi Decoction (ZXGD) in the treatment of myocardial infarction (MI) using the network pharmacology method and verifying by in vivo experiments and to reveal the underlying mechanism. Methods The chemical components of ZXGD and related targets were retrieved from the TCMSP database. The targets of MI were searched from the GeneCards, OMIM and DisGeNET databases, with the keywords " myocardial infarction" and "MI", and removing duplicates. The intersection of ZXGD and MI targets were obtained, and a protein-protein interaction (PPI) network based on the intersection of active ingredients and disease targets was constructed. The DAVID database was used to conduct GO and KEGG pathway enrichment analysis on the intersection targets. Combined with STRING database and Cytoscape 3.7.2 software, the intersection targets were visualized as a " medicine-component-target-disease" network. The MI mouse model was established by ligation of the left anterior descending coronary artery of the heart. ZXGD was given once a day for 14 days. The cardioprotective effects of ZXGD were examined by ultrasound cardiogram and Western blot. Results The results of network pharmacology analysis showed that the pharmacological components of ZXGD such as quercetin, naringenin, β-sitosterol, and luteolin maybe work on the targets like TNF-α, IL-1β, IL-6, VEGFA, and IL-10. Animal experiments found that compared with the model group, ZXGD significantly increased the left ventricular cardiac function, outflow tract blood flow, and other ultrasound indexes of the mice (P < 0.05). Moreover, the expression levels of IL-1β, TNF-α and IL-6 in myocardial infarction tissue were significantly down-regulated by ZXGD (P < 0.05), while the expression level of IL-10 was significantly up-regulated (P < 0.05). Conclusion ZXGD protects against MI and improves heart function by regulating inflammatory factors including TNF-α, IL-1β, IL-6, and IL-10.

ABSTRACT

Protein-protein interaction (PPI) plays an important role in the regulation of life. Most of the PPI interfaces are large and discontinuous, and it is difficult for small molecules to specifically bind to them. Peptides are critical in PPI surface interactions due to their higher affinity and specificity. However, peptides have some defects such as easy hydrolysis by protease and poor membrane permeability. Due to good biocompatibility and chemical diversity, cyclic peptides play an important role in drug discovery. Therefore, the development of efficient cyclic peptide construction methods has become a frontier issue in peptide drug research. In recent years, a series of new progresses have been made in the synthesis strategy and the application of cyclic peptides, providing powerful technical tools for the research and development of cyclic peptide drugs. In this review, the synthesis strategies of cyclic peptides and their application will be reviewed from four aspects: synthesis strategies, property improvement, biological activity and prospect.

ABSTRACT

OBJECTIVE: The perioperative chemotherapy with fluorouracil, leucovorin, oxaliplatin plus docetaxel (FLOT) was recommended by the Chinese Society of Clinical Oncology Guidelines for gastric cancer (2018 edition) for patients with resectable gastric or gastro-oesophageal junction adenocarcinoma (class IIA). However, the economic impact of FLOT chemotherapy in China remains unclear. The analysis aimed to compare the cost-effectiveness of FLOT versus epirubicin, cisplatin plus fluorouracil or capecitabine (ECF/ECX) in patients with locally advanced resectable tumours. DESIGN: We developed a Markov model to compare the healthcare and economic outcomes of FLOT and ECF/ECX in patients with resectable gastric or gastro-oesophageal junction adenocarcinoma. Costs were estimated from the perspective of Chinese healthcare system. Clinical and utility inputs were derived from the FLOT4 phase II/III clinical trial and published literature. Sensitivity analyses were employed to assess the robustness of our result. The annual discount rate for costs and health outcomes was set at 5%. OUTCOME MEASURES: The primary outcome of incremental cost-effectiveness ratios (ICERs) was calculated as the cost per quality-adjusted life years (QALYs). RESULTS: The base-case analysis found that compared with ECF/ECX, the use of FLOT chemotherapy was associated with an additional 1.08 QALYs, resulting in an ICER of US$851/QALY. One-way sensitivity analysis results suggested that the HR of overall survival and progression-free survival had the greatest impact on the ICER. Probabilistic sensitivity analysis demonstrated that FLOT was more likely to be cost-effective compared with ECF/ECX at a willingness-to-pay threshold of US$31 513/QALY. CONCLUSIONS: For patients with locally advanced resectable tumours, the FLOT chemotherapy is a cost-effective treatment option compared with ECF/ECX in China. TRIAL REGISTRATION NUMBER: NCT01216644.

ABSTRACT

Spectrally diverse fluorescent proteins (FPs) provide straightforward means for multiplexed imaging of biological systems. Among FPs fitting standard color channels, blue FPs (BFPs) are characterized by lower brightness compared to other spectral counterparts. Furthermore, available BFPs were not systematically characterized for imaging in cultured mammalian cells and common model organisms. Here we introduce a pair of new BFPs, named Electra1 and Electra2, developed through hierarchical screening in bacterial and mammalian cells using a novel dual-expression vector. We performed systematic benchmarking of Electras against state-of-art BFPs in cultured mammalian cells and demonstrated their utility as fluorescent tags for structural proteins. The Electras variants were validated for multicolor neuroimaging in Caenorhabditis elegans, zebrafish larvae, and mice in comparison with one of the best in the class BFP mTagBFP2 using one-photon and two-photon microscopy. The developed BFPs are suitable for multicolor imaging of cultured cells and model organisms in vivo. We believe that the described dual-expression vector has a great potential to be adopted by protein engineers for directed molecular evolution of FPs.

ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: Drug fever is frequently misdiagnosed, especially during concurrent infection. Celecoxib causes various adverse effects; however, celecoxib-induced drug fever is rarely reported. CASE SUMMARY: A 32-year-old man presented with pyrexia after 17 days of celecoxib therapy, which was reintroduced following 3-day total drug cessation. His fever recurred after this unsuspected rechallenge, which aided in the ultimate identification of the offending drug. A Naranjo Score of 8 led us to infer that drug fever was "probably" caused by celecoxib. WHAT IS NEW AND CONCLUSION: This is the first report of celecoxib-induced drug fever, aimed at assisting its diagnosis, particularly with rarely suspected causative drugs.
