Objective To investigate the influencing factors of shivering during anesthesia recovery in the patients with thoracolaparoscopic combined esophageal radical operation.Methods The related clinical da-ta in 298 patients with thoracolaparoscopic esophageal cancer radical operation in West China Hospital of Si-chuan University during 2019-2021 were retrospectively analyzed.The patients were divided into the shive-ring group (n=67) and non-shivering group (n=231) according to whether or not having shivering during the anesthetic recovery period.The univariate chi-square testing and binary logistic regression were used to an-alyze the independent risk factors for shivering occurrence.Results The univariate and multivariate logistic regression analysis results showed that the gender,age,intraoperative body temperature,anesthesia duration,intraoperative sufentanil dosage,postoperative pain score and intraoperative consumption of cisatracurium benzenesulfonate had statistical differences between the two groups (P<0.05).The multivariate logistic re-gression analysis results showed that the age≥60 years old (OR=3.124),intraoperative body temperature<36 ℃ (OR=2.994),anesthetic duration>6 h (OR=0.204),postoperative pain score≥5 points (OR=7.514),intraoperative cisatracurium benzenesulfonate dosage≥25 mg (OR=2.317),intraoperative remifentanil dosage≤45 μg (OR=5.466) were the independent risk factors for shivering occurrence during the anesthetic recovery period in the patients with thoracolaparoscopic combined esophageal radical operation (P<0.05).Conclusion There are several independent risk factors for shiver occurrence in the patients with thoracolaparoscopic combined e-sophageal cancer radical operation.

Objective To observe the application effect of magnetic resonance imaging technology in evaluating the brain structure and function of patients with type 2 diabetic painful neuropathy (PDN). Methods Forty patients with type 2 diabetes mellitus hospitalized in our hospital were selected as the study objects, and were divided into diabetes mellitus (DM) group (n=12), peripheral neuropathy (DPN) group (n=14) and PDN group (n=14). General clinical biochemical indexes of three groups were analyzed. The structural brain and function of brain area in three groups were compared. Results Age, duration of diabetes, systolic blood pressure, diastolic blood pressure, fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), free fatty acid (FFA), albumin (ALB), creatinine (Cr), uric acid (UA), estimated glomerular filtration rate (eGFR), cystatin C (Cys-C), total cholesterol (TC), triglyceride (TG) of the three groups were compared, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH), thyroglobulin antibody (TGAb), thyroid peroxidase antibody (TPO-Ab) and serum calcium (Ca) in the three groups showed no significant differences (P > 0.05). Compared with the DM group, the gray matter volume (GMV) in the DPN group was significantly decreased (P < 0.05). Compared with the DM group, amplitude of low frequency fluctuation (ALFF) and fractional amplitude of low frequency fluctuation (fALFF) of left medial superiorfrontal gyrus in the PDN group were significantly decreased (P < 0.05). Conclusion Abnormal GMV in the left angular gyrus in DPN patients may be associated with a higher risk of concomitant cognitive impairment. The decrease of ALFF in the right cerebellar vermis and fALFF in the left medial superior frontal gyrus in PDN patients may be related to the pathogenesis of pain.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.

Colorectal cancer (CRC) is the second most common cause of cancer-related death in the world. The pro-viral integration site for Moloney murine leukemia virus 1 (PIM1) is a proto-oncogene and belongs to the serine/threonine kinase family, which are involved in cell proliferation, migration, and apoptosis. Fibroblast growth factor receptor 1 (FGFR1) is a tyrosine kinase that has been implicated in cell proliferation, differentiation and migration. Small molecule HCI-48 is a derivative of chalcone, a class of compounds known to possess anti-tumor, anti-inflammatory and antibacterial effects. However, the underlying mechanism of chalcones against colorectal cancer remains unclear. This study reports that HCI-48 mainly targets PIM1 and FGFR1 kinases, thereby eliciting antitumor effects on colorectal cancer growth in vitro and in vivo. HCI-48 inhibited the activity of both PIM1 and FGFR1 kinases in an ATP-dependent manner, as revealed by computational docking models. Cell-based assays showed that HCI-48 inhibited cell proliferation in CRC cells (HCT-15, DLD1, HCT-116 and SW620), and induced cell cycle arrest in the G2/M phase through modulation of cyclin A2. HCI-48 also induced cellular apoptosis, as evidenced by an increase in the expression of apoptosis biomarkers such as cleaved PARP, cleaved caspase 3 and cleaved caspase 7. Moreover, HCI-48 attenuated the activation of downstream components of the PIM1 and FGFR1 signaling pathways. Using patient-derived xenograft (PDX) murine tumor models, we found that treatment with HCI-48 diminished the PDX tumor growth of implanted CRC tissue expressing high protein levels of PIM1 and FGFR1. This study suggests that the inhibitory effect of HCI-48 on colorectal tumor growth is mainly mediated through the dual-targeting of PIM1 and FGFR1 kinases. This work provides a theoretical basis for the future application of HCI-48 in the treatment of clinical CRC.

Objective To investigate the safety and effectiveness of perventricular device closure (PDC) for congenital ventricular septal defects (VSD) by a meta-analysis. Methods PubMed, The Cochrane Library, EMbase and China Biology Medicine (CBM) databases were searched for studies on PDC of VSD up to October 2018 by computer. We included studies only with more than 80% patients diagnosed with perimembranous VSD. A meta-analysis was performed to obtain pooled estimates of success rate and incidences of complications with 95% confidence interval (CI). Subgroup analysis stratified by percentage of perimembranous VSD was performed. Risk difference (RD) was used in the comparison of perioperative data with follow-up data. Results Fifteen studies (2 randomized controlled trials, 3 retrospective cohorts, and other 10 retrospective single-arm studies) involving 4 164 patients (3 848 patients with perimembranous VSD) were included in this meta-analysis. The pooled success rate was 95.4%. Incidences of residual shunt, aortic insufficiency, tricuspid insufficiency, and third-degree atrioventricular block were 5%, 0.1%, 3%, and less than 0.001% respectively. Improvements of residual shunt and aortic insufficiency were confirmed in follow-up patients. Conclusion PDC of congenital perimembranous VSDs is safe and yields good results. Because some limitations can not be overcomed, multicenter randomized controlled trials are needed to confirm our results.

Objective: To investigate a poisonous mushroom poisoning incident and analyze its clinical data. Methods: Investigate a poisonous mushroom poisoning incident in a place in Shandong in July 2018, at the same time, the clinical data of 2 cases of mushroom poisoning were analyzed and summarized. Results: The incident was caused by a poisoning incident caused by residents eating poisonous mushrooms. The poisonous mushroom in this incident was identified as a scaled white goose cream. Two patients with poisoning developed gastrointestinal symptoms such as nausea and vomiting, abdominal pain and diarrhea, and liver damage occurred later. After active rescue and treatment, one patient was discharged from hospital, and the other patient developed acute pulmonary embolism during the treatment. He was discharged after interventional thrombolysis and follow-up treatment. Conclusion After investigation, the incident was caused by the ingestion of poisonous mushrooms mainly based on the scalloped white goose cream. After active treatment, they were cured and discharged.

Objective To investigate the characteristics of clinical and cardiovascular magnetic resonance imaging(CMR) of arrhythmogenic cardiomyopathy with left ventricular(ALVC) involvement. Methods Ten cases of arrhythmogenic cardiomyopathy with left ventricular involvement and sixteen randomly chosen cases of arrhythmogenic cardiomyopathy with right ventricular (ARVC) involvement were enrolled in this study. Clinical symptoms, cardiac electrophysiological changes as well as the cardiac morpharage, ventricular functions and delayed enhancement of myocardium assessed by CMR were compared between the two groups. The size of heart chambers, global ventricular functions and the fat/fibrosis infiltration were evaluated by turbo fast spin echo, ture FISP cine and delayed enhancement. These were statistically analyzed by independent samples t test, respectively.Results There was no significant difference in age and gender between two groups. All the patients in two groups presented non-specific clinical manifestations with no significant differences (P>0.05) except for short of breath(P=0.034). The end-diastolic diameter of left ventricular, left ventricular end-diastolic volume index, left and right ejection fraction in ALVC and ARVC group were (64.2±7.7), (49.2±5.9) mm(t=5.551,P<0.001), (113.9±24.0), (69.2± 30.0) ml/m2(t=3.962, P<0.001), (38.5±3.1)%, (56.0±8.4)%(t=-6.733,P<0.001), (42.0±5.5)%, (18.0±7.3)%(t=8.817, P<0.001) respectively. An medium of 11 and 14 segments of fat or fat/fibrosis were found in intramural wall of the LV myocardiumin patients with ALVC,while only 0 segment(all P<0.001)was found in patients with ARVC.Conclusions The clinical manifestations of arrhythmogenic cardiomyopathy with left ventricular involvement was similar to ARVC, however, with regarding to cardiac morphological, functional and myocardial lesions, these two diseases have different characteristics in CMR features.“one-stop-shop”MRI examination has high value in the diagnosis of arrhythmogenic cardiomyopathy with Left ventricular involvement.

Background Pluripotent stem cell-derived retinal pigment epithelial (RPE) cells holds great promise for the treatment of age-related macular degeneration (AMD) and retinitis pigmentosa (RP),but the poor induction efficiency and the according high cost of RPE differentiation hindere its clinical applications.Curcumin is proved to have a promoting effect on the induced differentiation of embryonic stem cells (ESCs).However,the mechanism of curcumin on differentiation of human ESCs into RPE-like cells remains unclear.Objective This study aimed to explore the underlying molecular mechanism of curcumin on directed differentiation of human ESCs into RPE-like cells.Methods Human ESCs strains were cultured in the Matrigel-coated 6-well plate with mTeSRTM 1 medium until over-confluence,and basic fibroblast growth factor was withdrawn there after to induce automatic differentiation.Curcumin at the final concentration 1 μmol/L was added in the first day of differentiation for 24 hours,and the cells without curcumin in the medium served as the control group.Total RNA and protein were extracted at 3 weeks and 5 weeks after induction.RT-PCR,Western blot and immunofluorescence were performed to examine the expressions of the biomarks of stem cells and RPE cells as well as Wnt/β-catenin signaling pathway components.The endocytosis of polystyrene microsphere by induced RPE (iRPE) cells was investigated to verify their function of phagocytosis which features RPE cells.Results Pigmented cells were found from 3 weeks through 5 weeks after induction in the curcumin group,but only less pigmented cells were seen in the fifth week after induction in the control group.In the third and fifth week after induction,the relative expression levels of NANOG mRNA in the iRPE cells were significantly lower than those in the control group (t =13.086,P =0.022;t =34.186,P =0.004),and the relative expression levels of Pax6,RX,CRALBP and RPE65 mRNA were higher in the curcumin group than those of the control group (all at P＜0.01).Western blot assay showed that the expressing bands for CRALBP,RPE65 and MITF enhanced in iRPE cells with a similar appearance in human RPE cells.However,these expressions were all absent in human ESCs.Immunofluorescence staining showed the positive expressions of Pax6,MITF and ZO-1 in cytoplasm of iRPE cells in the curcumin group with a purified efficacy 100％.The fluorescence dye-doped polystyrene microspheres in cytoplasm were obvious in the iRPE cells like positive controls,but the polystyrene microsphere was absent in the negative controls.From 3 weeks through 5 weeks after induced,the relative expression levels of Lef1,MYC and TCF7 mRNA (the dwnstream target genes of Wnt signaling pathway),FZD3 mRNA (Wnt receptor),Wnt2B mRNA (Wnt ligand) and Wnt7B mRNA were significantly reduced in the curcumin group compared with the control group (all at P＜0.01).Conclusions Curcumin promotes the differentiation of human ESCs into RPE-like cells by stimulating the activation of Wnt signaling pathway,and therefore accelerate the differentiation and mature of iRPE cells.
