RESUMO
OBJECTIVE: To evaluate the efficacy and safety of endoscopic cyanoacrylate injection therapy for refractory high-risk peptic ulcer bleeding by conventional endoscopic therapy. METHODS: 154 patients with refractory high-risk peptic ulcer bleeding by conventional endoscopic therapy at the Affiliated Hospital of Zunyi Medical Univesity and the People's Hospital of Liupanshui City from January 2018 to December 2021were enrolled in this study. Endoscopic intracellular cyanoacrylate injection was first carried out. When failure, perintravascullar injection was carried out. The data were retrospectively collected. RESULTS: Among the 154 patients, 102 patients (66.23%) obtained successful intravascular injection and perivascular injection was performed in 52 patients (33.77%). Immediate hemostatic rate for active bleeding achieved 93.18%. Overall rebleeding rate within 30 days was 12.99% and successful hemostasis rate achieved 87.01%. Immediate hemostatic rate and successful hemostasis rate in intravascular injection patients were markedly superior over perivascular injection. Rebleeding rate in intravascular injection patients was markedly lower than that in perivascular injection patients. 14 patients complicated abdominal pain and no other complication occurred. CONCLUSION: Endoscopic cyanoacrylate injection therapy, especial intravascular injection, was effective and safe, with high successful hemostasis rate for refractory high-risk peptic ulcer bleeding by conventional endoscopic therapy.

RATIONALE: Rectal cavernous hemangioma is a rare, benign vascular disease that seldom causes lower gastrointestinal bleeding, characterized by a high rate of misdiagnosis and missed diagnoses. Surgical treatment is considered to be relatively effective; however, it is accompanied by certain employed in the treatment of superficial hemangioma, boasting the advantages of minimally invasive surgery, including safety, effectiveness, reduced trauma, and rapid recovery. However, there is a lack of literature regarding the application of foam sclerosing agents for gastrointestinal hemangiomas. CASE CONCERNS: We present a case of a 60-year-old male who was admitted to our hospital with a history of recurrent hematochezia for >1 year and worsening symptoms for 1 week. The patient's medical history was unremarkable. DIAGNOSES: Following colonoscopy, nuclear magnetic resonance imaging, computed tomography, and other examinations, the final diagnosis was rectal cavernous hemangioma. INTERVENTIONS: Due to the patient's refusal of surgery, endoscopic foam sclerotherapy using a lauromacrogol injection was performed after obtaining informed consent from the patient and their relatives. OUTCOMES: Post-sclerotherapy, hematochezia symptoms ceased, and no adverse reactions were observed. Two months later, colonoscopy and nuclear magnetic resonance imaging showed that the hemangioma had almost completely disappeared, with only a small amount of tumor remnants, yielding a satisfactory curative effect. CONCLUSION: Our findings indicate that endoscopic injection of a lauromacrogol foam sclerosing agent is a safe, effective, and minimally invasive treatment option for gastrointestinal cavernous hemangiomas.

BACKGROUND: According to practice guidelines, endoscopic band ligation (EBL) and endoscopic tissue adhesive injection (TAI) are recommended for treating bleeding from esophagogastric varices. However, EBL and TAI are known to cause serious complications, such as hemorrhage from dislodged ligature rings caused by EBL and hemorrhage from operation-related ulcers resulting from TAI. However, the optimal therapy for mild to moderate type 1 gastric variceal hemorrhage (GOV1) has not been determined. Therefore, the aim of this study was to discover an individualized treatment for mild to moderate GOV1. AIM: To compare the efficacy, safety and costs of EBL and TAI for the treatment of mild and moderate GOV1. METHODS: A clinical analysis of the data retrieved from patients with mild or moderate GOV1 gastric varices who were treated under endoscopy was also conducted. Patients were allocated to an EBL group or an endoscopic TAI group. The differences in the incidence of varicose relief, operative time, operation success rate, mortality rate within 6 wk, rebleeding rate, 6-wk operation-related ulcer healing rate, complication rate and average operation cost were compared between the two groups of patients. RESULTS: The total effective rate of the two treatments was similar, but the efficacy of EBL (66.7%) was markedly better than that of TAI (39.2%) (P < 0.05). The operation success rate in both groups was 100%, and the 6-wk mortality rate in both groups was 0%. The average operative time (26 min) in the EBL group was significantly shorter than that in the TAI group (46 min) (P < 0.01). The rate of delayed postoperative rebleeding in the EBL group was significantly lower than that in the TAI group (11.8% vs 45.1%) (P < 0.01). At 6 wk after the operation, the healing rate of operation-related ulcers in the EBL group was 80.4%, which was significantly greater than that in the TAI group (35.3%) (P < 0.01). The incidence of postoperative complications in the two groups was similar. The average cost and other related economic factors were greater for the EBL than for the TAI (P < 0.01). CONCLUSION: For mild to moderate GOV1, patients with EBL had a greater one-time varix eradication rate, a greater 6-wk operation-related ulcer healing rate, a lower delayed rebleeding rate and a lower cost than patients with TAI.

A membrane chromatographic method was developed for the rapid purification of vitellogenin (Vtg) from the plasma of 17beta-estradiol induced loach (Misgurnus angaillicaud atus) and carp (Cyprinus carpio). The time required for the proposed procedure is less then 10 min at a flow-rate of 5 ml/min of the mobile phase, and 0.5 ml of fish plasma could be separated in one cycle. Multistep gradient elution was more suitable for the separation than linear gradient elution. Under optimized conditions, a single Vtg peak can be obtained and its identity was confirmed by SDS-PAGE and gel-permeation chromatography assessment. This method is rapid and easy to operate compared to conventional HPLC and FPLC columns for Vtg separation.

BACKGROUND: There has been a high mortality and morbidity rate of critical and fatal patients from hand, foot and mouth disease (HFMD) in China in recent. Causes for development of critical and fatal disease remain unclear. METHODS: We performed a case-control study to assess the association between use of drugs and development of critical disease and death from HFMD. RESULTS: We found that glucocorticoids treatment was associated with a greater incidence of severe HFMD, whereas andrographolides treatment was associated with a protective effect when they are used for treatment within 48 hours after onset or before being diagnosed as critical. CONCLUSIONS: We recommend that glucocorticoids should not be used for mild HFMD and andrographolides should undergo clinical trials for treatment of enterovirus 71 infections.
