Objective To explore the application of ABCD3 score on stratifying the antithrombotic treatment strategy in patients with capsular warning syndrome (CWS).Methods The clinical features of 15 patients with CWS were analyzed retrospectively,and the risk of stroke were evaluated by ABCD3 score and to guide the treatment of Stratifying antithrombotic therapy.The status of patients hospitalized,discharged and discharged after 90 d were evaluated.Results The frequency of patients with CWS accounted for 2.51％ (15/ 597) of all patients with transient ischemic attack(TIA),and the mean age in patients with CWS was (70.27 ±8.29) years old.The duration of the first onset was (10-30) min,the mean time was (17.33±1.53) min,and ABCD2 score was 5.0-9.0 points,mean score was 7.00±0.26 points,and the total episodes of CWS were 51 times during 24 hours,the mean duration was (18.13 ± 15.36) minutes ((3.0-60.0) min).All 15 cases presented with limb hemiparesis.Of them,9 cases had dysarthria,5 case with ipsilateral facial palsy.All 15 cases CWS patients showed no signs of cortical deficit.The mean NIHSS score at onset was 1.0-6.0 points,mean scores was 3.20±0.31 points.Fourtheen patients were treated with clopidogrel plus aspirin,and 2 cases with administration of the loading dose 300 mg of clopidogrel,1 case was treated with clopidogrel plus aspirin orally followed by intravenous rt-PA thrombolysis.The average hospital periods of all 15 patients was (7.67±0.29) days.The NIHSS score were 0 point at discharge.There was no symptomatic intracranial hemorrhage or death within 90 days follow-up periods.Conclusion CWS is prone to develop a completed stroke.Stratified antithrombotic therapy guiding by ABCD3 score may decrease the risk of ischemic stroke.

This study was aimed to evaluate the frequencies and prognostic significance of the nucleophosmin 1 (NPM1) mutation, the fms-like tyrosine kinase 3 (FLT3) mutation and c-KIT mutation in acute myeloid leukemia (AML) and to explore their relevance to clinical characteristics, cytogenetics and survival. Genomic DNA from 78 newly diagnosed AML from August 2010 to October 2012 was screened by PCR and sequencing or capillary electrophoresis (CE) for NPM1, FLT3 and c-KIT mutations. The results showed that the incidence of NPM1 mutation was 14.1% in AML patients and 26.7% in normal karyotype AML patients. NPM1 mutant cases were significantly associated with old age (P < 0.05), high peripheral white cell count and platelet counts (P < 0.05) and low expression of CD34 (P < 0.05), but no statistic difference was found in sex, percentage of bone marrow blasts, Hb, expression of CD117 and HLA-DR, complete remission rate, overall survival and relapse rate (P > 0.05). The prevalences of FLT3-ITD and FLT3-TKD mutations were 11.5% (9/78) and 3.8% (3/78) respectively, and no one patient has both of the two mutations. Patients with FLT3-ITD mutation had higher white blood cell counts and percentage of in bone marrow blasts (P < 0.05), and lower overall survival (P < 0.05), more relative to normal karyotype (P < 0.05), while no statistic difference was found in sex, age, platelet count, Hb level, complete remission rate and relapse rate (P > 0.05). No statistic analysis was performed due to the cases of less FLT3-TKD mutation. C-KIT mutation accounts for 7.7% (6/78). Patients with C-KIT mutation had a higher percentage in abnormal karyotype (P < 0.05), and higher relapse rate (P < 0.05), and lower overall survival, whereas no statistic difference was found in sex, age, percentage of bone marrow blasts, peripheral blood cell count, complete remission rate (P > 0.05). It is concluded that the detection of NPM1, FLT3 and C-KIT mutations may contribute to guiding treatment and evaluating prognosis of patients with AML.

Objective To compare the performance of machine learning(ML)and individualized treatment effect(ITE)models based on deep learning in providing personalized treatment recommendations using real-world clinical datasets,and construct personalized drug treatment recommendation models for pegylated liposomal doxorubicin(PLD)and epirubicin(EPI)in postoperative breast cancer patients,and assist clinical decision-making by evaluating the treatment effects of these drugs.Methods Clinical data of 904 breast cancer patients admitted at Sir Run Run Shaw Hospital,Zhejiang University School of Medicine was collected retrospectively,including 387 cases treated with PLD and 517 cases treated with EPI.The two groups were compared using propensity score matching to assess the 5-year disease free survival(DFS)outcome.Six ITE models,including CFR_WASS,were used to predict the 5-year DFS probability of patients under two drug treatments.Six machine learning(ML)models,including Random Forest,were used as baselines for performance analysis and comparison.Model's Predictive performance was evaluated based on the AUROC.The effectiveness of treatment recommendations was assessed by calculating the difference of 5-year rates between the group where the actual treatment used was consistent with the treatment recommended by the model and the control group.Results Among the 153 matched cases,there was no statistically significant difference in 5-year DFS outcomes between the two groups.In 16 pairs of cases,the PLD group showed better clinical outcomes than the EPI group,and in 12 pairs of cases,the EPI group had better clinical outcomes than the PLD group,confirming individual differences in treatment benefit between the two drugs.The CFR_WASS model achieved the optimal predictive performance(AUROC value was 0.736 8),and there was no significant difference in 5-year DFS rates between most ML groups and the control group;The 5-year DFS rate in the ITE group was lower than that in the control group(P<0.01),showing significant differences.Among them,the 5-year DFS rate in the CFR_WASS group was 2.13%lower than that in the control group.Conclusion The ITE model is more accurate in estimating the individualized treatment effects of two drugs compared to the ordinary ML model,providing effective individualized treatment recommendations,and has certain clinical application value.

OBJECTIVEUsing the thyroid volume criteria for body surface area (BSA) to assess more precisely the effectiveness of removing iodized salt on the goiter status of children living in areas with excessive iodine in drinking water.

METHODSThree towns with median water iodine (MWI) of 150-300 µg/L were selected by simple random method in Hengshui city of Hebei province of China in May of 2010. A total of 452 and 459 children in the 3 towns were randomly selected to measure thyroid volume by ultrasound. Iodized salt was removed in July of 2010. In October of 2013, 459 children in these 3 towns were selected by simple random method to measure their thyroid volume by ultrasound again. Their goiter status was judged using the criteria of thyroid volume for BSA recommended by the WHO.

RESULTSAfter removing iodized salt, the overall BSA specific goiter prevalence in the three towns significantly decreased from 33% (149/452) to 6% (30/459) (χ² = 100.64, P < 0.001). The BSA specific goiter prevalence in 8, 9 and 10 year-old children decreased respectively from 38% (35/92), 31% (59/193) and 33% (55/167) to 6% (10/164), 7% (11/163) and 7% (9/132) (χ² values were 41.35, 31.66, 29.79, P < 0.001). The BSA specific goiter prevalence in boys and girls decreased from 34% (83/244) and 32% (66/208) to 6% (14/225) and 7% (16/234) (χ² values were 55.01, 45.06, P < 0.001) respectively.

CONCLUSIONThe BSA specific children's goiter prevalence decreased significantly after removing iodized salt from their diet in the HIA in Hebei province.

Objective:To study the characteristics and influence factors of laboratory test results of confirmed COVID-19 cases in Tianjin.Methods:Sample collection was conducted based on the standard operating procedure. Tianlong automatic magnetic bead nucleic acid extraction reagent was used for RNA extraction. Real-time RT-PCR was performed using four approved COVID-19 nucleic acid detection kits. Related epidemiological data of the cases were collected. One-way analysis of variance and non-parametric test for inter-group differences analysis were conducted using SPSS25.0 software.Results:A total of 162 PCR tests were completed for novel coronavirus nucleic acid detection in 123 confirmed COVID-19 cases. Eleven PCR results were positive for a single target gene and 10 of which were positive for nucleocapsid protein (N) gene. Nineteen cases were tested with two kinds of nucleic acid detection kits and the results of different detection kits were different. Different types of samples were collected form 13 cases for nucleic acid detection and the results showed that the Ct value of sputum sample was lower than that of throat swab sample. No significant difference in Ct values of throat swab samples was observed among patients with different clinical symptoms ( PCt-N=0.797, PCt-ORF1a/b=0.551). The 123 cases were divided into different groups according to the time interval between the onset date and the date of the first positive detection of viral nucleic acid. No significant difference in Ct values of throat swab samples was observed among different time interval groups ( PCt-N=0.373, PCt-ORF1a/b=0.058). Conclusions:Sputum samples were better than upper respiratory tract samples for viral nucleic acid detection. The sensitivity of N gene detection was higher, but re-sampling was needed when the result was positive for the single target N gene. Appropriate detection kits should be selected according to the actual needs, and samples should be collected at multiple time points, in multiple types and form multiple sites for detection.

Objective: To investigate the effect of non-vitamin K antagonist oral anticoagulants (NOAC) on left atrial or atrial appendage (LA/LAA) thrombi in patients with nonvalvular atrial fibrillation (NVAF). Method: Data from 3 042 patients with atrial fibrillation(AF), who underwent transesophageal echocardiography (TEE) examination before cardioversion or catheter ablation for the detection of LA/LAA thrombus in our department from March 2016 to January 2018 were prospectively analyzed. Among these patients, LA/LAA thrombus was detected by TEE in 57 patients. A total of 19 patients who received dabigatran or rivaroxaban for ≥3 weeks and underwent repeated TEE were included, 38 patients were excluded (7 patients with rheumatic heart disease, 1 patient treated with pericardial decortication, 1 patient treated with surgical repair of endocardial cushion defect, 1 patient with LA thrombus associated with the atrial septal occluder device, 14 patients received warfarin therapy, 14 patients did not receive repeated TEE). Results: First repeated TEE results showed that LA/LAA thrombus was not completely resolved in 4 out of 4 patients treated with dabigatran (110 mg bid) for a median time of 119 (47, 258) days, whereas LA/LAA thrombus was completely resolved in 5 out of 11 patients treated with dabigatran (150 mg bid) for a median time of 80 (58, 147) days. Thrombus was completely resolved in 2 out of 2 patients treated with rivaroxaban (15 mg qd) for 110 days and 95 days respectively, and in 1 out of 2 patients treated with rivaroxaban (20 mg qd) for 91 days. Second repeated TEE was performed in 8 patients. Thrombus was resolved completely in 2 out of 3 patients with undissolved thrombus treated by dabigatran (110 mg bid) after increasing the dabigatran dosage (150 mg bid). Thrombus was resolved in 3 (1 patient prolonged treatment with dabigatran 150 mg bid and 2 patients switched to rivaroxaban 20 mg qd) out of 4 patients with undissolved thrombus under the dabigatran 150 mg bid regimen, whereas the thrombus remained unresolved in 1 patient switched to rivaroxaban (15 mg qd). After receiving rivaroxaban 15 mg bid treatment, the thrombus was finally resolved in 1 patient with undissolved thrombus treated by rivaroxaban 20 mg qd. There was no clinical thromboembolism or major bleeding events during the median follow up time of 462 (305, 558) days. Conclusions Our data show that NOAC is an effective therapeutic option for the treatment of LA/LAA thrombi. When eligible, a higher NOAC dosage may be preferred due to the higher efficacy on thrombus resolvement.

Results:1.In terms of external influencing factors of personality development: on the part of life events, the score of family affair in the patient group was higher than that in the control group( P<0.05) in childhood.In terms of upbringing, the scores of strictness (5.637±3.463) and punishment (6.275±4.565) in the patient group were higher than those ((4.341±3.092), (5.000±3.698)) in the control group in childhood( t=-2.703, -2.093, both P<0.05). 2.In the aspect of personality elements: (1) Among courage subscales, the scores of natural fear (7.686±3.441) and adaptability (15.000±5.321) in the patient group were higher than those((6.023±3.991), (12.841±6.070)) in the control group in childhood ( t=-3.085, -2.613, both P<0.05) .For all three stages, interpersonal fear scores in the patient group ((20.284±8.255), (22.804±7.458), (22.725±7.145))were all higher than those ((16.205±7.937), (19.841±6.319), (18.364±6.277))in the control group( t=-3.458, -2.929, -4.437, P<0.01). (2) Among interpersonal relationship, the dependence dimension scores were higher in the patient group (10.804±3.621) than those (8.830±4.850) in the control group during childhood( t=-3.205, P<0.01). (3) Among sex development, the scores of heterosexual communications (11.941±4.878), love concept (15.098±4.180) and sexual concept (8.892±2.988) were higher in the patient group than those ((9.125±5.040), (11.761±5.202), (6.943±3.288)) in the control group in adolescence(all P<0.01). (4) Among ego, the score of self-care dimension in the patient group (6.465±2.890) was higher than that in the control group(4.239±2.861) in childhood ( P<0.01). In the dimension of autonomy, the scores of the patient group ((10.772±2.694), (11.347±2.621)) were higher than those in the control group ((8.011±4.039), (9.818±2.693)) in childhood and adolescence (both P<0.01). (5) Among the way of thinking, the score of absolute thinking dimension in the patient group was higher than that in control group in childhood ( P<0.01). In the dimension of cautious, the scores of patient group were higher than those in the control group in childhood and adolescence (both P<0.01). (6)Among volition, the scores of decisive dimension in the patient group were higher than those in the control group in adolescence and youth (both P<0.01). In the dimension of consciousness, the score of patient group was higher than that in the control group in youth( P<0.01). In the dimension of insistence, the score of the patient group were higher than those in the control group in childhood and youth (both P<0.01). (7) Among worldviews, the scores of motivations, perspective of career and perspective of friendship in the patient group were higher than those in the control group in adolescence (all P<0.01). The score of value dimension in patient group was lower than that in the control group in the youth ( P<0.01). Conclusion:Patients with OCD have more strictness and punishment during their childhood in terms of upbringing.This leads to a lack of courage, poor interpersonal relationships, low self-care or autonomy, high attachment, absolutization of thinking and suppressing themself more in their childhood.In their adolescence and youth, their lack of courage, poor self-care or autonomy and the way of thinking cautious and stubborn will further aggravate and gradually show a more conservative sexual development and traditional world outlook.

Type 2 diabetes mellitus is commonly associated with cardiovascular, renal complications, osteoporosis and other comorbidities. Sodium-glucose co-transporter 2 inhibitor (SGLT-2i) can reduce blood glucose level in patients with type 2 diabetes mellitus by promoting urine glucose excretion, and has the effect of weight loss and blood pressure reduction. Large randomized controlled clinical trials have shown that SGLT-2i can improve the prognosis of cardiovascular disease and diabetic nephropathy. This article focuses on the effects of SGLT-2i on cardiorenal outcomes and bone metabolism in addition to the glucose-lowering effect. SGLT-2i can improve the prognosis of patients with coronary atherosclerotic cardiovascular disease, reduce the risk of hospitalization for heart failure, reduce cardiovascular diseases and all-cause mortality, and has renal protective effect. Moreover, the cardiorenal protective effect is proved to be consistent in people without type 2 diabetes. SGLT-2i has a regulatory effect on bone mineral ions and bone metabolism related hormones, and its risk of osteoporosis and fracture deserves attention. Although data suggest that canagliflozin may increase fracture risk, meta-analyses of multiple clinical trials have concluded that SGLT-2i does not significantly increase fracture risk. However, for patients with high risk of fracture, bone mineral density and bone turnover biomarkers should be considered to assess the risk of fracture before prescription.

Objective:To investigate the safety and efficacy of submucosal tunnel docking endoscopic resection (SDER) for the treatment of giant submucosal tumors in the cardia.Methods:A retrospective analysis was performed on data of patients with giant submucosal tumors in the cardia who were treated with SDER at the endoscopy center of Zhongshan Hospital, Fudan University and Xuhui District Central Hospital from January 2021 to January 2022. The surgical records, postoperative pathology, complications, hospitalization, and follow-up were analyzed.Results:A total of 6 patients were included. The mean long diameter of the lesions was 4.0 cm, all of which were located in the cardia. All patients successfully underwent SDER treatment with a surgical time of 23-42 min. Postoperative pathology revealed that 4 cases were leiomyomas and 2 cases were gastrointestinal stromal tumors. All lesions were completely resected. The postoperative hospital stay was 3-5 d, and no serious complications occurred after surgery. All patients recovered on follow-up gastroscopy at 3 and 6 months postoperatively.Conclusion:The preliminary conclusion is that SDER for the treatment of giant submucosal tumors in the cardia is safe, effective.
