Objective To enhance the data quality of the front page of inpatient medical records.Methods Ten coders were engaged to perform manual quality control,and system verification rules were integrated for the basic information,diagnosis,treatment information,and hospitalization process information on the front page of inpatient medical records before and after the implementation of grid management.Results A total of 808 defects were found on the front pages of 728 inpatient medical re-cords.Among these deficiencies,basic information,diagnosis and treatment information,and process information accounted for 40.84％,3.96％,and 55.20％respectively.Totally,282 defects on the front pages of the 796 inpatient medical records man-aged under grid management.Among them,basic information,diagnosis and treatment information,and process information ac-counted for 39.00％,7.80％,and 53.19％,respectively.The overall defect rate was significantly decreased under grid manage-ment compared to the rate without it,(x2=6.553 5,P＜0.05).After the implementation of grid management,the numbers of the defects in admission condition,ID number incompletion,incision healing status,and coding were significantly decreased(P＜0.05).After the normalized coding of the ID number,the defect in ID number incompletion on the pages disappeared con-sequently.Conclusion Grid management reduces communication and feedback time,improves the data quality of the front page of inpatient medical records,and enhances problem-solving efficiency.It is important to coordinate the control of the data on the front pages of inpatient medical records to enhance standardization,consistency,and integrity.Moreover,it can also be applied to other areas of hospital management,offering scientific methods to optimize overall hospital operations.

Objective To formulate strategies for the construction of clinical specialty capabilities in hospitals,providing relevant experiences for peers to enhance clinical specialty capability development.Methods Taking a public hospital in Shenz-hen as an example,this study employs SWOT-PEST analysis to explore the external environment(opportunities and challenges)and internal environment(strengths and weaknesses)facing clinical specialty capability construction from four aspects:policy en-vironment,economic environment,social environment,and technological environment.Results The hospital's strengths include opportunities such as the construction of a national science city in the region,an aging population,and increased governmental fo-cus on the healthcare industry.Additional strengths include the integration of the hospital with community health services,strong support for key disciplines,and a deeply ingrained commitment to public welfare services.However,weaknesses include intense regional competition,the development of external internet hospitals,and increasingly strained doctor-patient relationships.The hospital also faces challenges due to inadequate research capabilities and levels,insufficient information technology infrastructure,and an incomplete internal incentive mechanism.Conclusion Based on the results of the SWOT-PEST analysis,the following strategies are proposed:SO Strategies(Strengths+Opportunities):Collaborate between the hospital and community health cen-ters;attract and cultivate talent to develop specialty clusters and key disciplines;and implement a comprehensive health manage-ment plan for the entire population and lifecycle in the region.ST Strategies(Strengths+Threats):Integrate management across various campuses and community health services,and pursue differentiated development.WO Strategies(Weaknesses+Opportu-nities):Engage in school-local collaborations for cross-disciplinary research innovation and translation;and deepen performance distribution reforms.WT Strategies(Weaknesses+Threats):Strengthen clinical research;enhance the hospital's information technology capabilities;and improve patient experience.Ultimately,these strategies aim to support the construction of clinical specialty capabilities within the hospital.

Objective To observe value of 0D-1D coupling model and 3D fluid-structure interaction(FSI)model based on coronary CT angiography(CCTA)for displaying hemodynamic characteristics of coronary artery stenosis.Methods Based on CCTA data of the stenosed left anterior descending branch(LAD)in a patient with coronary heart disease,an 0D-1D coupling model and 3D FSI model were built,respectively.Then hemodynamic characteristic indexes,including the pressure,flow velocity and wall shear stress(WSS)were obtained in every 0.01 s during 1 s at 5 sampling points(i.e.sampling point 1-5)using these 2 models,respectively,and the consistencies of the results between models were evaluated with Spearman correlation coefficient rs.Results The time consuming for construction of 0D-1D coupling model and 3D FSI model was 0.033 min and 704 min,respectively.Both models showed basically distribution of the pressure,flow velocity and WSS of the stenosed LAD.For more details,the pressure at the stenosed segment of LAD and the proximal segment of stenosis were both higher,which gradually decreased at the distal segment of stenosis,and the flow velocity at the proximal segment of stenosis was in a relatively slow and uniform condition,with significantly increased flow velocity and WSS at the stenosed segment.Compared with 3D FSI model,0D-1D vascular coupling model was relatively unrefined and lack of distal flow lines when displaying blood flow velocity.For sampling point 2 at the stenosed segment of LAD,no significant consistency for pressure between 2 models was found(P=0.118),but strong consistency for the flow velocity and WSS(rs=0.730,0.807,both P＜0.05).The consistencies of pressure,flow velocity and WSS between 2 models at the proximal and distal segment of stenosis,i.e.1,3-5 sampling points were week to moderate(rs=0.237-0.669,all P＜0.05).Conclusion 0D-1D coupling model exhibited outstanding computational efficiency and might provide relatively reasonable results,while 3D FSI model showed higher accuracy for details and streamline when simulating LAD stenosis.

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.

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.

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.

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 investigate the nutritional status of children acute lymphoblastic leukemia (ALL) during induced remission stage. The effects of the disease itself, treatment, and complications of malnutrition were all analyzed. Methods: From the medical re-cords of children with ALL in the pediatric hematological department of the Affiliated Hospital of Guizhou Medical University, we col-lected basic information of the children; monitored the height and weight of the children on the first, 15th, and 33rd days of induced remission treatment; and calculated their body mass index (BMI), as well as results of laboratory tests such as serum albumin and se-rum prealbumin. SPSS 23.0 software was used for data analysis. Results: In 40 children with ALL, there were 16 cases of malnutrition on the first day of induced remission treatment accounting for 40%, 14 cases on both the 15th day and the 33rd day of treatment ac-counting for 35%. Among children with malnutrition, 4 cases of moderate to severe malnutrition occurred on the first day of treat-ment accounting for 25.0%, 9 cases on the 15th day accounting for 64.3%, and 12 cases on the 33rd day accounting for 85.7%. Com-pared with day 1 and day 33, the difference was statistically significant (P<0.017). In the induced remission period, the BMI on the first day was (15.98±2.17) kg/m2; on the 15th day, it was (15.65±2.20) kg/m2; and on the 33rd day, it was (15.66±1.92) kg/m2. The differ-ence between the three was not statistically significant (P=0.730). In the single-factor analysis of factors related to the nutritional sta-tus of children, infection, digestive system involvement, and serum albumin levels were related to the occurrence of malnutrition, and we performed multifactor analysis of these three factors. The difference between the level of infection and serum albumin and the oc-currence of malnutrition was statistically significant (P<0.05). Conclusions: During the induced remission, the malnutrition degree of some children with ALL was aggravated. Infection was a high-risk factor for malnutrition in children with ALL. The decrease in serum al-bumin level may indicate the occurrence of malnutrition. Dynamic monitoring of nutritional status in children with ALL is necessary.
