Objective To discuss the application of day surgery management mode in patients with cardiovascular interventional treatment, evaluate the safety of day surgery and its effects on the average in-hospital days and expenses. Methods A total of 1 578 patients who received cardiovascular interventional therapy in the Department of Cardiology in Ningbo First Hospital from January 2015 to December 2016 were included in the study. They were randomly divided into the observation group and the control group, 789 cases respectively. Patients in the control group received normal in-hospital operation mode, while patients in the observation group used day surgery mode. The safety, complications, average in-hospital days and expenses were compared between two groups. Results The average in-hospital days and expenses were 1 d and 3 083 Yuan in the observation group; in the control group, average in-hospital days and expenses were (5.34±0.73) d and (3 713.70±21.06) Yuan, which were significantly higher than those in the observation group (P<0.05). There were 5 cases of bleeding in the puncture site of the radial artery, 9 cases of forearm hematoma, and 1 case of Iodine allergic reaction with a complication incidence of 1.9% in the control group. In the observation group, there were 3 cases of bleeding in the puncture site of the radial artery, 6 cases of forearm hematoma, and 2 cases of Iodine allergic reaction with a complication incidence of 1.4%. No significant difference in the complications of patients was observed between two groups (P>0.05). Conclusions The day surgery mode of patients with cardiovascular interventional treatment, which can ensure the therapeutic effect and the safety of patients, is feasible and can reduce the average in-hospital days and expenses.

Objective: Cerebrovascular disease can be roughly divided into 2 subtypes: Cerebral ischemia (CI) and cerebral hemorrhage (CH). No scale currently exist that can predict the subtypes of cerebrovascular diseases. This study aims to establish a prediction scale for the subtypes of cerebrovascular diseases. Methods:A total of 1200 cerebrovascular disease patients were included in this study, data from 1081 (90％) patients were used to establish the CI-CH risk scale, and data from 119 (10％) patients were used to test it. Risk factors for the CI-CH risk scale were identified by 2 screens, with two-tailed student ' s t-test and two-tailed Fisher ' s exact test preliminarily and with logistic regression analysis further. The scores of each risk factor for CI-CH risk scale were determined according to the odds rate, and the cut-off point was determined by Youden index. Results: Nine risk factors were ultimately selected for score system, including age (≥75 years old was ?1, <75 years old was 0), BMI (<24 kg/m2 was 0, 24?28 kg/m2 was ?1,>28 kg/m2 was?2), hypertension grade (grade 1 was 1, grade 2 was 2, and grade 3 was 3), diabetes status (no was 0, yes was?1), antihypertensive drug use (no was 0, yes was?2), alcohol consumption (<60 g/d was 1, ≥60 g/d was 2), uric acid (less than normal was 0, normal was?1, high than normal was?2), LDL cholesterol (<2 mmol/L was 0, 2?4 mmol/L was?1, and>4 mmol/L was?2), and HDL cholesterol (<1.55 mmol/L was 0,≥1.55 mmol/L was 2). Patients with a score more than 0 were classified as the CH group, Conversely, they were assigned to the CI group;its sensitivity, specificity, and accuracy were 74.5％, 77.9％, and 76.4％, respectively. Conclusion: The CI-CH risk scale can help the clinician predict the subtypes of cerebrovascular diseases.

Objective : The present study observed the clinical effects on reattachment and pulpotomy of young crown-fractured and pulp-exposed permanent incisors. Methods : In a one-year retrospective clinical observation study, 30 traumatic intact segments of permanent incisors with crown fracture and pulpal exposure were treated using a pulpotomy and reattachment technique with an enamel-dentin luting agent and composite resin. Results : The number of subsequent visit teeth was 30, 29, 25 at 1, 3, 6 months follow-up respectively. The pulpotomy success rates were 100% at 1 month, 93.1% at 3 months, 93.1% at 6 months. The retention rates using the reattachment technique were 100% at 1 month, 100% at 3 months, 100% at 6 months. Conclusion Pulpotomy is the preferred method of preserving live pulp after pulpal exposure of young permanent incisors, and the clinical effect is prominent. The fragment reattachment technique is an effective middle- and short-term method for temporary restoration of young crown-fractured permanent incisors.

Traditional Chinese medicine(TCM)polysaccharides are active polysaccharides extracted from Chinese herbal medicines,many of which exhibit specific biological activities.Modern research has revealed that polysaccharide components extracted from plants,animals,and algae have a significant role in improving kidney injury.Currently,drug therapy is the primary treatment for kidney injury,with few reports on the use of TCM polysaccharides.This review explores the therapeutic effects and mechanisms of TCM polysaccharides on diabetic nephropathy,nephritis,kidney stones,hypertension-induced kidney injury,chemical toxin-induced kidney injury,and drug-induced kidney injury.Additionally,it discusses the prospects for the development of TCM polysaccharides in this field to provide a reference for further research.
