Objective To explore the clinical characteristics and influencing factors of primary nephrotic syndrome (PNS) combined with hypercoagulability in children. Methods The clinical data of 57 children with primary PNS were analyzed retrospectively. The clinical features and treatment were compared among high coagulation state group, non high coagulation state group and control group (20 children). At the same time, the differences between the simple nephrotic syndrome group (SNS) and nephritic syndrome group (NNS) in hypercoagulable state were analyzed. In addition, the correlation analysis was performed. Results Among 57 patients, there were 50 patients in high coagulation state group and 7 in non high coagulation state group. There was no significant difference in gender, age and clinical manifestations between two groups (P>0.05). The platelet (PLT) count, platelet aggregation (PCT), albumin (Alb), fibrinogen (Fib), D-dimer (D2) were significantly higher than those in the control group, and there were statistically significant differences (P all<0.01). There were significant differences in the levels of PLT, Fib, D2 and complement C4 between hypercoagulable state group and non hypercoagulable state group (P all<0.05). There were significant differences in HCT, TC, LDL, PT and complement C3 levels between SNS group (n = 32) and NNS group (n =18) in 50 patients with high coagulation state (P<0.05). There was positive correlation between HCT and complement C3 (r=0.30, P<0.05), while there was no correlation between PLT and other indices (P>0.05). All of the 57 patients were improved and has no thrombosis after the treatment. Conclusion Children with primary PNS were usually associated with different degrees of hypercoagulable state, and PLT, Fib, D2 could be used as reference indices for the severity of hypercoagulable state, and the activation of complement system might be related to the occurrence and development of hypercoagulable state.
6.How to standardize the enhanced recovery after surgery in clinical practice?
Chinese Journal of Gastrointestinal Surgery 2022;25(7):563-567
The enhanced recovery after surgery (ERAS) protocol is an evidence-based perioperative care pathway, which is to reduce the perioperative stress and metabolic variation, with the ultimate goal of improving patient recovery and outcomes. This article reviews some hot issues in the clinical practice of ERAS in China. Currently, the concept and pathways of ERAS are very consistent with China's medical reform, and the basic principle of "safety first, efficiency second" should be adhered to. In specific clinical practice, multidisciplinary cooperation, the improvement of surgical quality and the implementation of prehabilitation pathway should be advocated. In addition, the ERAS approaches should be implemented individually to avoid mechanical understanding and dogmatic implementation. The implementation of ERAS and its clinical outcome should be audited to accumulate experience, and a feedback mechanism should be established to improve the outcome continuously. In clinical practice, "fast recovery" should not be the sole purpose. For patients, the decrease in the risk of readmission rate is more important as compared to discharge rate. Additionally, the disparities between the development of ERAS clinical research in China and that in the world are also analyzed in this review. A national ERAS database should be established on the basic platform of academic groups to ensure the development of high-quality clinical research in China.

Objective The homological analysis of a foodborne disease outbreak event that occurred on July 15, 2022, in Sanya was carried out to provide scientific basis for clinical treatment, incident tracing and prevention and control, and to explore the feasibility of pulsed field gel electrophoresis (PFGE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) in the homology analysis of Salmonella bacteria. Methods The traceability analysis of food poisoning incidents was accurately analyzed through the combination of traditional bacterial detection methods, PFGE, MALDI-TOF MS and the clinical symptom, epidemiological characteristics. Results In this outbreak, 14 cases of poisoning symptoms such as fever, nausea, and vomiting appeared, all of which had a history of dining in the same restaurant, with similar onset and clinical manifestations. Among them, one was the chef who made the fried rice in the restaurant. The pathogen culture and identification showed that it was caused by Salmonella typhimurium and Salmonella choleraesuis. Among the 14 cases of patients, 5 cases of Salmonella choleraesuis, 3 cases of Salmonella typhimurium, with the positive rate of 57.14% (8/14). One case of environment and two cases of food were detected. The result of PFGE showed nine PFGE types, 95.00% homology for 7 strains, and 94.00% homology for 4 strains. Conclusions The food poisoning was caused by eating egg fried rice containing Salmonella choleraesuis and pork intestine containing Salmonella typhimurium. In the future, , it is necessary to strengthen the risk monitoring of food contamination and harmful factors, to ensure food safety from the source of food supply, and to prevent the occurrence of foodborne infection events. At the same time, it is also crucial to standardize the health check of related personnel, and to conduct multi-channel education on the harm and prevention of foodborne diseases.

Singapore medical journal 2013;54(10):564-568
INTRODUCTIONThe level of participation is an important factor influencing rehabilitation outcome. However, few studies have evaluated rehabilitation participation and its clinical predictors in patients with stroke. This study aimed to establish the level of participation in patients with stroke undergoing inpatient rehabilitation, and define the clinical predictors for participation.
METHODSThis was a prospective observational study of first-time patients with stroke admitted to a rehabilitation centre over a 12-month period. The primary outcome measure was the level of rehabilitation participation as measured on the Pittsburgh Rehabilitation Participation Scale (PRPS). PRPS measurements were made one week after admission and one week before planned discharge from inpatient rehabilitation. Other outcome measures evaluated were the National Institute of Health Stroke Scale, Functional Independence Measure (FIM), Elderly Cognitive Assessment Questionnaire (ECAQ), Centre for Epidemiologic Studies-Depression Scale, Fatigue Severity Scale (FSS), Lubben Social Network Scale-Revised, and Multidimensional Health Questionnaire.
RESULTSA total of 122 patients with stroke were studied. The mean PRPS score on admission was relatively high at 4.30 ± 0.90, and this improved to 4.65 ± 0.79 before planned discharge (p < 0.001). On multivariate analysis, the mean PRPS score on admission was predicted by FIM, EACQ and FSS scores on admission, but not by variables such as age, gender, depression, social support, or health attitudes and beliefs.
CONCLUSIONPatients with lower levels of participation were more likely to be functionally dependent, cognitively impaired and have more fatigue. We suggest that in addition to cognition, fatigue should be routinely screened in patients with stroke undergoing rehabilitation.

OBJECTIVETo discuss the clinical findings and treatment of paraneoplastic pemphigus (PNP) with Castleman's disease.
METHODSTo investigate the clinical, histopathologic and CT findings of 8 cases paraneoplastic pemphigus with Castleman's disease.
RESULTSAll of 8 patients were diagnosed PNP first and were found Castleman's tumor incidently during routine examination. All 8 cases showed severe erosion or ulcer of the oral mucosa with various skin lesions. Histopathologically, there were intraepidermal acantholytic vesicle, basal cell liquefaction, necrotic keratinocytes in the epidermis and lymphocyte infiltration in the upper dermis. CT scan appeared solitary mass in these patients. Some of them were attacked by bronchiolitis obliterans. All 8 patients were failed by use of predisone. Obvious relief of PNP and pulmonary lesion occurred after tumor was rescted.
CONCLUSIONSParaneoplastic pemphigus with Castleman's disease is a rare disease. The key step is to find and resect the tumor in abdomen. CT scan should be used to detect the tumor in patients with PNP, especially, when predisone was failed in treatment.
