Objective To investigate the application of improved ABCD2 scoring for predicting the onset of cerebral infarction within 7 days after transient ischemic attack (TIA).Methods A total of 133 patients with TIA adnitted from July 2014 to December 2015 were enrolled in this study.The ABCD2 scoring and ABCD2 combined with carotid ultrasound (CU) scoring were used to predict the risk of cerebral infarction occurred within 7 days after TIA.The univariate analysis and multivariate logistic regression analysis were performed to estimate the contribution of clinical risk factors to triggering the cerebral infarction within 7 days after TIA.Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of two different kinds of scoring process in early cerebral infarction after TIA.Results Of 133 patients with TIA,35 (26.3％) suffered from cerebral infarction within 7 days after TIA.Univariate analysis showed cerebral infarction occurred within 7days after TIA was closely associated with BP≥ 140/90 mmHg,unilateral weakness,speech impairment,TIA duration ≥ 10 minutes,past history of hypertension,diabetes mellitus,carotid plaque,and carotid stenosis.Multivariate logistic regression analysis showed that unilateral weakness (OR =3.52,95％ CI:1.76-12.34),TIA duration ≥ 10 minutes (OR =2.45,95％ CI:1.06-9.27),diabetes mellitus (OR =3.37,95％ CI:1.27-10.94),past history of hypertension (OR =4.15,95％ CI:1.71-13.34),carotid plaque (OR =6.32,95％ CI:2.46-19.40),and carotid stenosis (OR =12.73,95％ CI:2.67-44.35) were significantly correlated with early onset of cerebral infarction after TIA (all P ＜ 0.05).The ROC analysis revealed the ABCD2-CU scoring (AUC =0.802,95％ CI:0.717-0.888,P =0.000) had a larger area under curve compared to ABCD2 scoring (AUC =0.614,95％ CI:0.511-0.717,P =0.036).Conclusions The ABCD2-CU scoring was more accurate in predicting the imminent risk of cerebral infarction in the patients with TIA compared to ABCD2 scoring.And ABCD2 scoring combined with carotid ultrasound could improve the accuracy for predicting the risk of cerebral infarction occurred within 7 days after TIA.

Objective To study the curative effect and influence on memory function of Gabapentin (GBP) as add-on therapy for treatment of focal seizures in refractory epilepsy. Methods 96 patients with focal seizures in refractory epilepsy were randomly divided into groups GBP and Topiramate (TPM). Beside the normal medicaments, GBP or TPM as add-on therapy for certain group. According to the Clinical Memory Scale (CMS), the patient's memory function was evaluated before and after treatment. Results There was no significantly difference of total effective rate between groups GBP (75.0%) and TPM (72.9%). The scores of CMS showed almost same between before or after add-on therapy in GBP group. In TPM group, the scores of meaningless image recognition, free recall, phase portrait characteristics and memory quotient were significantly reduced after add TPM(allP

Objective To discuss the accuracy and objectivity of student standardized patients (SSP) in objective structured clinical examination(OSCE). Methods On March 30 and 31, 2013, 168 seven-year program medical students of class 2006 and 2007 took part in OSCE. Differences in as-sessment results between SPP and those given by professional doctors at 3 SP sites(angina pectoris SSP station, acute cholecystitis SSP station, depression SSP station) were analyzed. Each site had 4 items for assessment, with a total score of 100. Scores were given in strict accordance with a set of unified scoring rules. Counting data were presented as x±s. Data were verified using t test. P<0.05 was considered statis-tically considerable. Results At angina pectoris station, respective scores of SSP and professional physi-cians were 85.2±7.1 and 85.5±6.6, P=0.688. At acute cholecystitis station, respective score of SSP and professional physicians were 89.1±5.2 and 88.2±6.2, P=0.150. At depression station, respec-tive score of SSP and professional physicians were 79.8±7.5 and 78.2±7.0, P=0.078. Conclusion There is no statistical difference between scores given by SSP and those given by the physicians in OSCE. This proves that SSP who received standardized training delivers fair and accurate results in OSCE , and therefore is recommended for future application.

Objective: To investigate correlations between motor skills with focused and shifting attention among preschool children, and to provide basis for the overall development of preschool children aged 4-6 years. Methods: During March to June 2020, a total of 165 preschool children aged 4-6 years were selected and investigated with subscales of the Bruininks Oseretsky Test of Motor Proficiency 2nd Edition (BOT-2) for agility and limb bilateral coordination assessment, and subscales of the Movement Assessment Battery for Children test 2nd Edition (MABC-2) for throwing and catching skill assessment, as well as balance subscale for the assessment of limb movement coordination, hand eye coordination, agility, and balance. The Kansas Reflection Impulsivity Scale for Preschoolers for Pre schoolers (KRISP) and Dimensional Change Card Sort (DCCS) were used to assess focused and shifting attention levels. Correlation and linear regression analyses were performed for statistical analysis. Results: Except for one handed throwing skills and shifting attention, there were statistically significant gender differences between boys and girls in total score of body movement coordination, total score of hand to eye coordination, hand to hand connection, total score of agility of movement, total score of movement balance, static support, walking on tiptoe, foot to foot jump and focused attention( t =-6.86, -2.00 ,-3.15,-3.75,-3.00,-2.95,-2.18,-2.11,-3.21, P ＜0.05), and girls were better than boys; children s total score of body movement coordination, total score of hand to eye coordination, hand to hand connection, agility of movement, walking on tiptoe and focused attention improves with age( r =0.47,0.41,0.47,0.51,0.16,0.31, P ＜0.05); After excluding the interference of gender and age, total score of body movement coordination was significantly correlated with preschool children s focused attention( β=0.31,95%CI =0.08-0.39, P ＜0.01). Conclusion Limb movement coordination and focused attention are significantly and positively correlated among preschool children aged 4-6 years. Therefore, preschool education and family activities should focus on designing and developing limb movement coordination related games and courses to enhance the focused attention of and form favorable attention quality in preschool children aged 4-6 years.

ObjectiveTo explore the ideal minimally invasive surgical method for degenerative lumbar spine stenosis.MethodsFrom March 2008 to August 2010,73 cases with lumbar spinal stenosis underwent minimal invasive surgery were retrospectively analyzed.The patients were divided into different groups by clinical features,imaging manifestations,and concurrent diseases.The minimal invasive surgical methods were chosen according to the classification.Operation time,intra-operative bleeding,and complications were recorded.The lumbar function was evaluated by Oswestry disability index (ODI),and the clinical results were assessed by JOA pre- and postoperatively.ResultsMinimal invasive surgery was completed in all cases,which included 25 cases with bilateral decompression and 48 cases with unilateral approach for bilateral decompression.Twenty-three cases used interbody fusion and percutaneous pedicle screw fixation after decompression.Intraoperative blood loss and operation time were related to surgical methods.One case was complicated with dural tear.Cage was inserted into upper vertebral body during interbody fusion in 1case with osteoporosis,removed the cage and implanted bone fusion.Incisions of 3 cases were poor healing after surgery.The average follow up time was 13 months(range,10-35).JOA score and ODI before surgery were 9.2±5.1 and 62.3％±18.5％ respectively; while 6 months after surgery,JOA score and ODI were 23.5±7.2 and 18.4％±6.4％ respectively.JOA score and ODI showed statistically significant improvements after operation(P＜0.01).Twenty-two cases got solid fusion at the final follow-up.ConclusionTreatment of lumbar spinal stenosis by minimal invasive surgery has satisfactory surgical outcomes,but the proper minimal invasive strategy should be chosen according to specific patients,surgeons and hospitals.

Purpose: Nurses play an important role in ensuring patient rehabilitation and are involved in all aspects of multidimensional rehabilitation.Therefore, strengthening rehabilitation nursing education is vital to ascertain high-quality rehabilitation and optimum outcomes. This study examined the effectiveness of a new teaching reform—a modified Six-Sigma-based training program—against a conventional educational program on rehabilitation specialist nurses’ core competencies, post-training performance, and satisfaction. Methods: A quasi-randomized controlled trial was conducted to assess the effectiveness of the modified training program. We recruited 56 learners from the 2020 training course at the Hunan Rehabilitation Specialist Nurse Training Base as the control group. Sixty learners from the base’s 2021 training course were recruited as the intervention group. Data were collected in a consistent manner from both groups after the training program was implemented. Results: Those who underwent the modified training program showed better improvement in all core competencies than those who underwent the conventional training program (p < .05); the scores for theoretical knowledge, clinical nursing lectures, reviews, and nursing case management improved significantly following the teaching reform (p < 0.05). Further, overall satisfaction as well as base management and theoretical teaching satisfaction improved significantly (p < .05). Conclusion The modified training program strengthens rehabilitation nurses’ base management abilities; enhances their core competencies; expands their interest in and breadth, depth, and practicability of theoretical courses; and updates the teaching methods.

Objective:To investigate the current application of colonoscopy at hospitals in China.Methods:From November 2019 to January 2020, an online questionnaire survey was conducted among gastroenterologists and colonoscopists in hospitals of different levels. The contents of questionnaire survey included basic information of colonoscopy at the respondent′s hospital, protocols and patient education of bowel preparation, implementation of colonoscopy quality control, and colonoscopists′ understanding of polypectomy techniques and post-polypectomy follow-up.Results:A total of 236 valid questionnaires were collected, involving 187 hospitals, and 143 (76.5%) had an annual operation capacity of more than 5 000 cases. In terms of bowel preparation, split-dosed polyethylene glycol electrolyte powder (PEG) was the most commonly used (60.4%, 113/187) and the most common volume of PEG was 3 L (67.4%, 126/187). Verbal (90.9%, 170/187) and written (79.7%, 149/187) instructions were given more often than other methods for patient education of bowel preparation. Antifoaming agent was routinely used in 124 (66.3%) hospitals. In terms of quality control, only 11.5% (20/174) hospitals implemented all four measures. In terms of polypectomy techniques, 98.1% (203/207) colonoscopists chose hot snare polypectomy or endoscopic mucosal resection for lesions of diameter>1 cm, while options varied for lesions of diameter<1 cm. The interval of follow-up after polypectomy recommended by colonoscopists was shorter than that by guidelines.Conclusion:Several problems are found in the survey in the application of colonoscopy in China, i. e., patient education of bowel preparation is not diversified; quality control of colonoscopy still needs to be strengthened; polypectomy techniques and follow-up after polypectomy need to be further standardized.

Objective:Grasp the status of Zhejiang entry standards, controls and calibrators in recent years and problems.Methods:Through descriptive statistics, cross-tab chi-square, and comparation of means method , we collected and sorted out relevant information about standard products, quality control products and calibrators of the Zhejiang Provincial Biomedical Special Articles Entry Centralized Supervision Platform, and analyzed the basics of standard products, quality control products and calibrators situation, degree of dependence and utilization.Results:The standard products and quality control products imported into Zhejiang province are mainly used for scientific research of biomedical device enterprises. 76.6% of imported standard products, quality control products and calibrators cannot be domestically produced. The main origin of imported standard products and quality control products is the United States, and the main origin of standard products is the United Kingdom.Conclusions:The standard products, quality control products and calibration products imported into Zhejiang province are currently lacking in domestic production capacity. It is recommended to support the research and development and production of domestic standard products, quality control products and calibration products.

Objective:To investigate the short-term efficacy of laparoscopic total gastrec-tomy with hand-sewn esophagojejunostomy versus Roux-en-Y anastomosis.Methods:The propen-sity score matching and retrospective cohort study was conducted. The clinicopathological data of 159 patients who underwent laparoscopic total gastrectomy in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine from October 2014 to July 2021 were collected. There were 107 males and 52 females, aged 63(range, 28?79)years. Of 159 patients, 71 cases undergoing totally laparoscopic total gastrectomy with hand-sewn esophagojejunostomy were allocated into totally laparoscopic group and 88 cases undergoing laparoscopic-assisted total gastrectomy with Roux-en-Y anastomosis were allocated into laparoscopic-assisted group, respectively. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and postoperative conditions; (3) perioperative complications. Propensity score matching was done by the 1:1 nearest neighbor matching method. Measurement data with normal distribution were expressed as Mean± SD, and t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M(range), and the Mann-Whitney U test was used for comparison between groups. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher's exact probability method. The rank sum test was used for comparison of ordinal data. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of 159 patients, 112 cases were successfully matched, including 56 cases in the totally laparoscopic group and 56 cases in the laparoscopic-assisted group. Before propensity score matching, age, cases with tumor located in cardia or gastric body in the totally laparoscopic group were 61(range, 30?76)years, 26, 45, respectively. The above indicators in the laparoscopic-assisted group were 65(range, 28?79)years, 50, 38, respectively. There were significant differences in the above indicators between the two groups ( Z=?2.89, χ2=6.43, P<0.05). After propensity score matching, the males and females, age, body mass index, cases of American Society of Anesthesiologists classification Ⅰ, Ⅱ, Ⅲ and Ⅳ, tumor diameter, cases with tumor located in cardia or gastric body, cases in TNM stage Ⅰ, Ⅱ and Ⅲ of patients in the totally laparoscopic group were 40, 16, (62±9)years, (22.7±2.8)kg/m 2, 22, 26, 7, 1, 3.5(range, 0.6?17.0)cm, 24, 32, 22, 9, 25. The above indicators of patients in the laparoscopic-assisted group were 38, 18, (62±10)years, (22.7±3.2)kg/m 2, 19, 32, 5, 0, 4.0(range, 0.6?15.0)cm, 23, 33, 21, 7, 28, respectively. There was no significant difference in the above indicators between the two groups ( χ2=0.17, t=?0.09, ?0.04, Z=?0.12, ?0.82, χ2=0.04, Z=?0.42, P>0.05). The elimination of age and tumor location confounding bias ensured comparability between the two groups. (2) Intraoperative and postoperative conditions: after propensity score matching, the total operation time, time of esophagojejunostomy, postopera-tive 24-hour pain numerical score and time to first out-off bed activities were (310±49)minutes, (37±10)minutes, 2.3±0.8 and (2.4±0.7)days for patients in the totally laparoscopic group, versus (344±77)minutes, (44±12)minutes, 3.1±1.2 and (2.9±1.0)days in the laparoscopic-assisted group, showing significant differences between the two groups ( t=?2.85, ?3.05, ?4.20, ?3.10, P<0.05). (3) Perioperative complications: after propensity score matching, 6 cases of the patients in the totally laparoscopic group had Clavien-Dindo grade 2 or higher complications, including 2 cases of anas-tomotic leak, 1 case of anastomotic stenosis, 1 case of pleural effusion, 1 case of abdominal infection and 1 case of intestinal obstruction. The incidence of Clavien-Dindo grade 2 or higher complications was 10.7%(6/56). In the laparoscopic-assisted group, 5 patients had Clavien-Dindo grade 2 or higher complications, including 2 cases of anastomotic leak, 1 case of abdominal infection, 1 case of intestinal obstruction and 1 case of cholangitis. The incidence of Clavien-Dindo grade 2 or higher complications was 8.9%(5/56). There was no significant difference in the incidence of Clavien-Dindo grade 2 or higher complications between the two groups ( χ2=0.10, P>0.05). Patients with anas-tomotic leak were improved after puncture and drainage, secondary surgery and conservative treat-ment, and other complications were improved after symptomatic treatment. Conclusions:Com-pared with Roux-en-Y anastomosis in laparoscopic total gastrectomy, the time of hand-sewn esophagojejunostomy and esophago-jejunal anastomosis are shorter, patients have less postopera-tive pain and faster postoperative recovery. Both methods have good peri-operative safety.

Objective:To investigate the application value of hand-sewn esophagojejunal anastomosis (EJA) in totally laparoscopic total gastrectomy (TLTG).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 35 patients with early or advanced upper gastric cancer who were admitted to Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine between July 2018 and December 2019 were collected. There were 24 males and 11 females, aged (60±10)years, with a range of 35-75 years. All the 35 patients underwent TLTG combined with hand-sewn EJA. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) postoperative pathological examination; (4) follow-up and survival. Follow-up was conducted using telephone interview, outpatient examination, short message service and WeChat to detect tumor recurrence, metastasis and survival of patients up to January 2020.Measurement data with normal distribution were repressented as Mean± SD. Measurement data with skewed distribution were represented as M (range). Count data were expressed as absoulte numbers or persentages. Results:(1) Intraoperative situations: all the 35 patients underwent TLTG combined with hand-sewn EJA successfully. The operation time, volume of intraoperative blood loss, time of hand-sewn EJA, costs of consumables used in the intraoperative resection and reconstruction, and costs of consumables used in EJA of the 35 patients were 305 minutes(range, 232-406 minutes), 94 mL(range, 50-300 mL), 37 minutes(range, 20-65 minutes), 13 674 yuan(range, 11 929-15 255 yuan) and 491 yuan(range, 223-1 044 yuan), respectively. Of the 35 patients, 4 received intraoperative blood transfusion. (2) Postoperative situations: time to first out-of-bed activity, postoperative indwelling time of gastric tube, time to initial liquid diet intake, the time to abdominal drainage tube removal and duration of postoperative hospital stay of the 35 patients were 2 days(range, 1-3 days), 4 days(range, 2-11 days), 5 days(range, 4-12 days), 8 days(range, 5-15 days) and 9 days(range, 7-16 days), respectively. Of the 35 patients, 3 had perioperative complications. One patient had inflammation and infection in the pancreatic tail and was discharged at postoperative 16 days after conservative treatment of fasting, somatostatin to reduce the pancreatic secretion, adequate drainage, anti-infection and nutritional support. One had postoperative intestinal incomplete obstruction and was discharged at postoperative 12 days after treatment with gastrointestinal decompression and enema for relief of obstruction. One had pulmonary infection who was discharged at postoperative 9 days after symptomatic and supportive treatment. None of the 35 patients had perioperative anastomotic leakage or bleeding. Of the 35 patients, 1 was diagnosed with esophagojejunostomy stenosis at postoperative 2 months and was improved after endoscopic dilatation. The incidence of long-term anastomosis-related complications of the 35 patients was 2.9%(1/35). (3) Postoperative pathological examination: the pathological examination of the upper margin of intraoperative frozen section and postoperative paraffin section showed negative in the 35 patients. Of the 35 patients, 16 had tumor located at cardia including 4 cases with tumor involving in lower esophagus, 19 had tumor located at stomach; 21 had tumor pathological type as highly or moderately differentiated adenocarcinoma, 11 had poorly differentiated adenocarcinoma, 3 had signed-ring cell carcinoma; 14 had early gastric cancer, 21 had advanced gastric cancer; 7 had tumor invaded at mucosa lamina propria and muscularis, 7 had tumor invaded at submucosa, 1 had tumor invaded at muscularis, 1 had tumor invaded at subserosal, 17 had tumor invaded at serosal, 2 had tumor invaded at extra-serosal adipose tissue. The TNM staging of the 35 patients: 14 were in stage ⅠA , 2 in stage ⅠB, 4 in stage ⅡB, 3 in stage ⅢA, 4 in stage ⅢB and 8 in stage ⅢC. Of the 35 patients, 15 had vascular invasion and 16 had nerve invasion. The tumor diameter, the number of lymph nodes dissected and the number of positive lymph nodes of the 35 patients were 3.9 cm(range, 0.6-12.0 cm), 24(range, 10-40) and 2(range, 0-11). (4) Follow-up and survival: all the 35 patients were followed up for 1-18 months, with a median time of 5 months. Of the 35 patients, tumor recurrence or metastasis was not found in 34 patients, and the other 1 patient was diagnosed with liver metastases of tumor at postoperative 6 months and survived with tumor.Conclusion:Hand-sewn EJA in TLTG is safe and feasible.
