Objective To investigate the factors influencing gastrointestinal bleeding associated with esophagogastric fundal varices bleeding(EGVB)in patients with liver cirrhosis 5 years after endoscopic treatment.Methods A retrospective enrollment was conducted on 181 patients with liver cirrhosis who underwent endoscopic treatment with EGVB at the First Affiliated Hospital of University of Science and Technology of China from February 2017 to May 2019,followed up for a minimum duration of 5 years.The demographic characteristics including gender,age,etiology of liver cirrhosis(viral,alcoholic,autoimmune,others),presence of ascites,hepatic encepha-lopathy severity(none,stage 1～2,stage 3),portal vein thrombosis status,occurrence of liver cancer or portal hypertensive gastric disease along with other complications were recorded.Additionally,peripheral blood indexes[aspartate aminotransferase(AST),alanine aminotransferase(ALT),white blood cell count(WBC),total biliru-bin(TBIL),albumin(ALB),platelet count(PLT)],prothrombin time parameters[prothrombin time(PT)and prothrombin time international normalized ratio(PTINR)],portal vein diameter and splenic vein diameter measure-ments as well as Child grade assessment were collected alongside sequential treatment details and rebleeding time.According to the occurrence of rebleeding within 5 years after endoscopic treatment,the 181 cases were divided into two groups:the non-rebleeding group(n=124)and the rebleeding group(n=57).Univariate and multivariate analyses were conducted to identify risk factors associated with rebleeding within 5 years after endoscopic treatment.Additionally,Kaplan-Meier analysis was performed to assess the cumulative bleeding rate at 1,3,and 5 years.Results The results of both univariate analysis and binary logistic regression analysis revealed that elevated TBIL levels and increased portal vein diameter were significant risk factors for rebleeding within 5 years following endo-scopic treatment in patients with EGVB(P<0.05).The Kaplan-Meier curve demonstrated that out of the 181 patients,there were 41 cases of cumulative bleeding within 1 year,54 cases within 3 years,and 57 cases within 5 years,resulting in cumulative bleeding rates of 22.65%,29.83%,and 31.49%respectively.Conclusions The long-term rebleeding rate remains elevated following endoscopic treatment of EGVB in cirrhotic patients,with TBIL levels and portal vein diameter identified as independent risk factors for long-term rebleeding after endoscopic treatment of EGVB in liver cirrhosis.Therefore,patients with higher TBIL levels and/or cirrhosis should be given priority for endoscopic treatment of EGVB.

Objective:To investigate the effect of power PICC with two different external lengths in patients with hematologic diseases.Methods:From August 2020 to August 2021, a retrospective analysis was conducted on 233 cases of hematologic diseases who received power PICC catheterization in Department of Hematology, the Nanfang Hospital of Southern Medical University, the patients were divided into 0-1 cm group (132 cases) and 2-4 cm group (101 cases) according to the external lengths after catheter insertion. The incidence of related complications and patient comfort at 24 hours, 72 hours, 7 days and 14 days after catheterization were compared between the two groups.Results:At 24 hours and 72 hours after catheterization, the incidence of bleeding at puncture point in 0-1 cm group was 14.39%(19/132) and 9.85%(13/132), in 2-4 cm group was 30.69%(31/101) and 32.67%(33/101), the difference was statistically significant ( χ2=9.02, 14.16, both P<0.05). The rate of redness and swelling of punture point at 7 days after catheterization was 9.09%(12/132) and 40.59%(41/101) in the two groups, with statistical significance ( χ2=32.32, P<0.05). The rates of slightly prolapse at 7 and 14 days after catheterization were 18.18% (24/132) and 18.94%(25/132) in 0-1 cm group, 59.41% (60/101) and 67.33%(68/101) in 2-4 cm group, the difference between the two groups was statistically significant ( χ2=42.18, 55.86, both P<0.05). In the observation of comfort at 14 days after catheterization, the comfort score of patients in the 0-1 cm group was significantly higher than that in the 2-4 cm group, and the difference between the two groups was statistically significant ( χ2=7.34, P<0.05). Conclusions:Patients with hematologic diseases can reduce the risk of bleeding and slightly prolapse, and improve the comfort of patients when the external lengths is 0-1 cm of power PICC, which is worthy of clinical application and promotion. The catheterizer should adopt accurate in appropriate measurement method to determine the best lengths of the catheters.

Objective:To compare the efficacy and safety of endoscopic sclerotherapy with polycinnamol solution and foam in the treatment of grade II hemorrhagic internal hemorrhoids.Methods:From September 2020 to June 2021, 81 patients with grade II hemorrhagic internal hemorrhoids were collected from the Department of Gastroenterology, the First Affiliated Hospital of University of Science and Technology of China. They were randomly divided into an observation group and a control group. The observation group was injected with polycinnamol solution, and the control group was injected with polycinnamol foam. All of them were treated with endoscopic sclerotherapy. The clinical data of the two groups were compared and analyzed. The operation time, immediate hemostasis rate, incidence of postoperative complications (such as fever, pain, bleeding and Urinary retention), recurrence and rebleeding rate of the two groups were observed, and the efficacy and safety of the two groups in the treatment of grade II hemorrhagic internal hemorrhoids were compared.Results:There was no statistically significant difference in basic data between the two groups of patients (all P>0.05), indicating comparability. The surgical operation time of the observation group patients [(7.40±1.18)min] was shorter than that of the control group [(13.88±0.95)min] ( P<0.05); The injection dose of polycinnamol [(5.79±1.61)ml] in the observation group was higher than that in the control group [(4.38±1.92)ml] ( P<0.05). The immediate postoperative hemostasis rate in the observation group was the same as that in the control group (100%). The incidence of postoperative fever (7.32%), perianal pain (4.88%), bleeding (7.32%), and urinary retention (4.88%) complications in the observation group had no significant difference from that in the control group [postoperative fever (5.00%), anal pain (7.50%), bleeding (7.50%), and urinary retention (2.50%)] (all P>0.05). Two months after surgery, the rebleeding rate in the observation group (4.88%) was not significantly different from that in the control group (7.50%) ( P>0.05), but the rebleeding score in the observation group (1.21±0.63) was lower than that in the control group (2.62±0.71), with a statistically significant difference ( P<0.05). The rebleeding rate (2.44%) and the rebleeding score (2.33±1.51) in the observation group were lower than those in the control group [the rebleeding rate (12.50%) and the rebleeding score (5.54±2.42)] at 12 months after follow-up, and the differences were statistically significant ( P<0.05). Conclusions:Endoscopic sclerotherapy is effective in the treatment of grade II hemorrhagic internal hemorrhoids. There is no significant difference in the immediate and short-term hemostasis rate and the incidence of complications between two different dosage forms of sclerotherapy, namely, polycinnamol solution and foam, but the operation of the solution injection is more time-saving and the long-term recurrence rate is lower, which is worthy of clinical application.

In order to evaluate the safety and effectiveness of endoscopic hemorrhoids treatment, a retrospective analysis was conducted on data of 166 patients with grade I to Ⅲ hemorrhoids who underwent endoscopic treatment in the First Affiliated Hospital of University of Science and Technology of China from January 2018 to June 2020 with complete follow-up data. There were 35 cases in the simple sclerotherapy group, 104 cases in the simple ligation group, and 27 cases in the ligation combined sclerotherapy group. The results showed that, no serious complications occurred in the 3 groups after surgery. In the simple ligation group and the ligation combined with sclerotherapy group, the incidence of postoperative anal pain [35.6% (37/104) and 33.3% (9/27), respectively,] and anal pendant distension [70.2% (73/104) and 70.4% (19/27), respectively] were higher, but symptoms could be tolerated or relieved after simple treatment. The satisfaction of patients in the 3 groups was all more than 90% before discharge, and the degree of operation acceptance was more than 95%. The effective rate of the 3 groups was above 90.0% at 3 months after surgery, At 12 months after surgery, the effective rate of the simple sclerotherapy group was the lowest [74.3% (26/35)], and the effective rate of the other two groups was still above 85.0%. In conclusion, minimally invasive treatment for internal hemorrhoids under endoscopy is safe and effective with effective improvement of symptoms, high postoperative satisfaction of patients and high degree of acceptance.

BACKGROUND: Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion. METHODS: Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test). RESULTS: We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies. CONCLUSION: The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.

From April 2017 to June 2020, 46 patients with acute non-variceal upper gastrointestinal bleeding (ANVUGIB) underwent endoscopic vascular embolization (EVE) in the Department of Gastroenterology of the First Affiliated Hospital of University of Science and Technology of China for rebleeding after endoscopic hemostasis therapy (including local drug injection, electrocoagulation, hemostatic clamp and ligation, etc.). All 46 patients immediately stopped bleeding after EVE, and the effective rate of immediate hemostasis was 100.0%. Postoperative abdominal pain occurred in 13 cases (28.3%), abdominal distension in 3 cases (6.5%) and fever in 2 cases (4.3%). The mucosa healed gradually under gastroscopy 3 and 12 months after the operation. No gastrointestinal rebleeding occurred during the follow-up. Therefore, EVE is a safe and effective method for ANVUGIB patients with failure of initial endoscopic hemostasis, which is worthy of further clinical study and application.

BACKGROUND: AND PURPOSE: Previous studies have explored the association between retinal vascular changes and cognitive impairment. The retinal vasculature shares some characteristics with the cerebral vasculature, and quantitative changes in it could indicate cognitive impairment. Hence, a comprehensive meta-analysis was performed to clarify the potential relationship between retinal vascular geometric changes and cognitive impairment. METHODS: Relevant databases were scrupulously and systematically searched for retinal vascular geometric changes including caliber, tortuosity, and fractal dimension (FD), and for cognitive impairment. The Newcastle-Ottawa Scale was used to evaluate the methodological quality of included studies. RevMan was used to perform the meta-analysis and detect publication bias. Sensitivity analyses were also performed. RESULTS: Five studies that involved 2,343 subjects were finally included in the meta-analysis. The results showed that there was no significant association between central retinal artery equivalents (Z=1.17) or central retinal venular equivalents (Z=1.74) and cognitive impairment (both p>0.05). Similarly, no significant difference was detected in retinal arteriolar tortuosity (Z=0.91) and venular tortuosity (Z=1.31) (both p>0.05). However, the retinal arteriolar FD (mean difference: −0.03, 95% CI: −0.05, −0.01) and venular FD (mean difference: −0.03, 95% CI: −0.05, −0.02) were associated with cognitive impairment. CONCLUSIONS A smaller retinal microvascular FD might be associated with cognitive impairment. Further large-sample and well-controlled original studies are required to confirm the present findings.

Objective The evaluation index system of quality of assisted fertility treatment care was constructed to provide the basis for scientific evaluation of quality of care in reproductive center. Methods Based on the structure-process-outcome (SPO) quality model, evaluation index system for fertility treatment care in the reproductive center was constructed by literature query, field process tracking, Delphi expert consultation and analytic hierarchy process (AHP). Results The effective recovery rate ( RR ) of the two rounds of the questionnaire was 100% . The expert authority coefficient Cr values were 0.813, 0.845 respectively. The W value of the coordination coefficient was 0.331, 0.372, both of which were statistically significant (P<0.01). Finally, an evaluation index system of quality of assisted fertility treatment care with three dimensions, 14 secondary indicators and 47 items was formed. Yaaph software was used to determine the weight coefficients of primary and secondary indicators, and the consistency test ( Cr<0.1) was performed, and the variation coefficients of all tertiary items were <0.20. Conclusions The weight of the quality index system of assisted reproductive treatment care in reproductive center is reasonable, the indicators were clear, systematic and objective, and worthy of clinical promotion.

Objective To explore the application of 64 slice low dose spiral CT in pediatric paranasal sinus examination.Methods Sixty children with paranasal sinuses were randomly divided into three groups(control group,low dose 1 group,low dose 2 group),and were given conventional dose scanning(100 KV in tube voltage,100 mA in tube current),low dose scanning(100 KV in tube voltage,45 mA in tube current),and low dose scanning (100KV in tube voltage,25 mA in tube current).The single scan weighted CT dose index (CTDIw) of each patient was recorded and compared;and the quality of the scanned images of each group was evaluated by two chief physicians by blind method.Results Compared with conventional dose group,low dose 1,2 groups had significantly lower CTDIw,and the dose decreased for 59.23％ and 72.42％ respectively.The image quality of the low-dose 1 group did not change significantly,and all the images could meet the requirements of clinical diagnosis;but the image quality of the low-dose 2 group decreased significantly,and the images of 3 patients could not meet the requirements of clinical diagnosis.Conclusion Appropriate reduction of scanning parameters for paranasal sinuses children can not only obtain good quality images,but also effectively reduce the radiation dose of patients.
