Objective To investigate the risk factors for cerebral microbleeds (CMBs) and its correlation with the 24 h microalbuminuria (mALB) in patients with small artery occlusion (SAO).Methods The patients with SAO were enrolled.CMBs were detected with susceptibility-weighted imaging.The demographic and clinical characteristics and 24 h mALB of the patients were compared.Multivariate logistic regression analysis was used to identify the independent risk factors for CMB in patients with SAO.Spearman correlation analysis was used to investigate the correlation between the 24 h mALB and the degree of CMBs.Results A total of 90 patients with SAO were enrolled and 35 patients (38.89％) had CMBs.CMBs mainly distributed in basal ganglia/thalamus and infratentorial (62％) regions.The Age (70.8 ± 5.4 vs.67.3 ± 8.1; t =2.461,P =0.016),proportion of hypertension (80.0％ vs.52.7％ ;x2 =6.851,P =0.009),and 24 h mALB levels (16.257 ± 6.031 mg/24 h vs.11.910 ±5.458 mg/24 h; t =3.536,P =0.001) in the CBM group were significantly higher than those in the non-CMB group.Spearman rank correlation analysis showed that the 24 h mALB and the severity of CMB in patients with SAO showed a significant positive correlation (rs =0.795,P =0.000).The higher the 24 h mALB level was,the more severe the CMB degree would be.Multivariate logistic regression analysis showed that only 24 h mALB was the only independent risk factor for CMBs in patients with SAO (odds ratio,1.100,95％ confidence interval 1.031-1.176; P =0.002).Conclusions The 24 h mALB is an independent risk factor for CMB in patients with SAO.The 24 h mALB level is positively correlated with the severity of CMB,and it may be used as a marker for small vascular injury.

To investigate the curative effect of electroacupuncture on luteinized unruptured follicle syndrome(LUFS) and its mechanism. Methods:Sixty LUFS patients were randomly allocated to treatment (electroacupuncture) group and control (hCG) group. The follicular condition and ovarian arterial flow under color Doppler ultrasonogaphy and a change in reproductive endocrine level were observed in the patients before and after treatments. The ovulation rates and pregnancy rates were compared between the two groups,and the mechanism was investigated. Results:Both ovulation rate and pregnancy rate were significantly higher in the treatment group than in the control group (P＜0.01). There was a significant difference in the improvement in ovarian arterial flow between the treatment and control groups (P＜0.01). The improvement in endocrine level was significantly more marked in the treatment group than in the control group(P＜0.01). Conclusion:Electroacupuncture has a good effect on luteinized unrupture follicle syndrome. Its mechanism may be related to the improvement in ovarian arterial blood supply and the regulation of endocrine level.

Purpose: Tumor recurrence is the principal cause of poor outcomes in remnant gastric cancer (RGC) after resection. We sought to elucidate the recurrent patterns according to tumor locations in RGC. Materials and Methods: Data were collected from the Shanghai Cancer Center between January 2006 and December 2020. A total of 129 patients with RGC were included in this study, of whom 62 had carcinomas at the anastomotic site (group A) and 67 at the non-anastomotic site (group N). The clinicopathological characteristics, surgical results, recurrent diseases, and survival were investigated according to tumor location. Results: The time interval from the previous gastrectomy to the current diagnosis was 32.0±13.0 and 21.0±13.4 years in groups A and N, respectively. The previous disease was benign in 51/62 cases (82.3%) in group A and 37/67 cases (55.2%) in group N (P=0.002). Thirty-three patients had documented sites of tumor recurrence through imaging or pathological examinations. The median time to recurrence was 11.0 months (range, 1.0–35.1 months). Peritoneal recurrence occurred in 11.3% (7/62) of the patients in group A versus 1.5% (1/67) of the patients in group N (P=0.006). Hepatic recurrence occurred in 3.2% (2/62) of the patients in group A versus 13.4% (9/67) of the patients in group N (P=0.038). Patients in group A had significantly better overall survival than those in group N (P=0.046). Conclusions The tumor location of RGC is an essential factor for predicting recurrence patterns and overall survival. When selecting an optimal postoperative follow-up program for RGC, physicians should consider recurrent features according to the tumor location.

Objective:To construct a scientific and objective evaluation system for the in-service training of "double-qualified" clinical nursing teachers.Methods:From August 2020 to March 2021, the framework was preliminarily constructed through literature analysis, and the evaluation system was constructed by Delphi method and analytic hierarchy process.Results:The authority coefficients of the two rounds of expert consultation are 0.82 and 0.81 respectively, and the overall coordination coefficients are 0.24 and 0.21 respectively. As a result, we construct the evaluation system for the in-service training of "double-qualified" clinical nursing teachers, included 8 first-level indicators, 39 second-level indicators and 39 groups of grading rules.Conclusions:The evaluation index system for the on-the-job training of "dual-teacher" clinical nursing teachers constructed in this study can provide a reference for the reform of the current "dual-teacher" clinical nursing teachers′ on-the-job training, and improve the quality of teacher training, and guarantee the quality of nursing teaching.
