Objective To analyze the correlative factors and cause of death within short-term in initially lucid patients with intracerebral hemorrhage (ICH).Methods 441 patients with spontaneous ICH admitted within 24 hours of onset and with Glasgow Coma Scale (GCS) score more than 9 on admission were enrolled. The demographic characteristics, clinical features at onset, CT, electrocardiograph (ECG) and laboratory findings, medical complications and 27 days outcome were recorded. Univariate and multivariate analysis were performed.Results 24 (5.4%) patients died winthin 27 days after onset, 14 (58.3%) died of brain herniation and central respiratory failure, another 10 (41.7%) of systemic complications. Multivariate analysis demonstrated that age was 75 years old or more, urinary incontinence at onset, peripheral white blood cell count more than 10.0?10 9/L on admission, blood glucose more than 7.0 mmol/L and abnormal ECG were independent correlative factors of death.Conclusions The short-term outcome of initially lucid patients with ICH is favorable in general, albeit with a relatively low mortality. Brain herniation and central respiratory failure were main cause of death, and they have independent correlative risk factors.

Objective To assess the diagnosis value of diffusion- weighted imaging (DWI) in Creutzfeldt-Jakob disease (CJD).Methods 8 cases of sporadic CJD who underwent MRI were reported. 4 cases were definite,3 cases were probable and 1 case was possible. The sensitivity of DWI and conventional MRI were compared. Results T_1WI and T_2WI revealed no abnormal signals except nonspecific diffuse brain atrophy in 4 cases, whereas DWI detected hyperintense abnormalities in all cases. 2 cases showed linear lesions only in the cerebral cortex, and 6 cases showed lesions in both the cerebral cortex and the striatum. The lesions were symmetric in 5 cases, but were asymmetric in the other 3 cases. Although fluid-attenuated inversion recovery (FLAIR) imaging also showed cortical hyperintensity in 1 case, the high signal changes were more evident and extensive on DWI. Conclusions The hyperintense changes in the cerebral cortices and/or striata on DWI are considered characteristic of CJD. DWI is more sensitive than conventional MRI in depicting lesions of CJD and may be an essential tool for the early diagnosis of this disease.

Objective:This study aims to explore the anticancer effects and potential mechanisms of HJC0152, a novel STAT3 inhibitor, on the invasion and migration capacities of human head and neck squamous cell carcinoma (HNSCC) cell lines in vitro. Methods:Cells were divided into two groups, the dimethyl sulfoxide (DMSO) group and the HJC0152 group in which HNSCC cell lines UM-1 and SCC-15 were treated with DMSO or HJC0152 for 24 h. The total expression levels of STAT3, p-STAT3 (Tyr705/Ser727), MMP-2/9, N/E-cadherin, TWIST1, and vimentin;and the cytoplasm and nuclear expression levels of STAT3 and p-STAT3 (Tyr705/Ser727) were detected by Western blot assay. Wound healing and Transwell assays were employed to detect the invasion and migration abilities of the UM-1 and SCC-15 cells. The expression and location of N/E-cadherin were visualized by immunofluorescence staining. Results:Western blot indicated that the total expression of p-STAT3 (Tyr705), MMP-2/9, N-cadherin, TWIST1, and vimentin were significantly declined and that E-cadherin was remarkably elevated in the HJC0152 group cells compared with that of the DMSO group, with no difference in STAT3 or p-STAT3 (Ser727). Cytoplasm and nuclear STAT3 (Tyr705) were also inhibited by HJC0152. Wound healing and Transwel assays indicated that tumor invasion and migration capacities were impressively attenuated in the HJC0152 group cells compared to that of the DMSO group. Conclusion:HJC0152 suppresses the phosphorylation of STAT3 at Tyr705 in the HNSCC cell lines, leading to impair transcription activity, deplete expression levels of target genes, and subsequently inhibit migration and invasion capabilities of HNSCC.

Objective To evaluate the relationship between diabetic nephropathy(DN)and diabetic retinopathy(DR)in patients with type 2 diabetes mellitus(T2DM)based on imaging and clinical testing data.Methods Totally 600 T2DM patients who visited the First People's Hospital of Ziyang from March 2021 to December 2022 were included.The fundus photography and fundus fluorescein angiography were performed on all these patients and their age,gender,T2DM duration,cardiovascular diseases,cerebrovascular disease,hypertension,smoking history,drinking history,body mass in-dex,systolic blood pressure,diastolic blood pressure and other clinical data were collected.The levels of fasting blood glu-cose(FPG),triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipo-protein cholesterol(LDL-C),glycosylated hemoglobin(HbA1c),24 h urinary albumin(UAlb),urinary albumin to creati-nine ratio(ACR),serum creatinine(Scr)and blood urea nitrogen(BUN)were measured.Logistic regression was used to analyze the risk factors associated with DR.DR staging was performed according to fundus images,and the convolutional neural network(CNN)algorithm was used as an image analysis method to explore the correlation between DR and DN based on emission computed tomography(ECT)and clinical testing data.Results The average lesion area rates of DR and DN detected by the CNN in the non-DR,mild-non-proliferative DR(NPDR),moderate-NPDR,severe-NPDR and pro-liferative DR(PDR)groups were higher than those obtained by the traditional algorithm(TCM).As DR worsened,the Scr,BUN,24 h UAlb and ACR gradually increased.Besides,the incidence of DN in the non-DR,mild-NPDR,moderate-NPDR,severe-NPDR and PDR groups was 1.67%,8.83%,16.16%,22.16%and 30.83%,respectively.Logistic regression analysis showed that the duration of T2DM,smoking history,HbA1c,TC,TG,HDL-C,LDL-C,24 h UAlb,Scr,BUN,ACR and glomerular filtration rate(GFR)were independent risk factors for DR.Renal dynamic ECT analysis demonstrated that with the aggravation of DR,renal blood flow perfusion gradually decreased,resulting in diminished renal filtration.Conclusion The application of CCN in the early stage DR and DN image analysis of T2DM patients will improve the diag-nosis accuracy of DR and DN lesion area.The DN is worsening as the aggravation of DR.

Objective Visual electrophysiology and optical correlation tomography angiography(OCTA)were used to investigate differences in preoperative retinal function in patients with type 2 diabetic cataract(DC)without obvious retinopathy(NDR)and to determine the clinical application of whole-process blood glucose man-agement(WBGM)for improving postoperative vision in DC patients.Methods This study investigated the preop-erative and postoperative visual electrophysiology(N75,P100,photopic FERG,and scotopic FERG),peripapil-lary retinal nerve fiber layer(pRNFL)and peripapillary capillary vessel density(ppVD)data,as well as trends in these data changes during blood glucose management intervention.Results As the course of T2DM progressed,FBG and HbA1c increased,the N75 and P100 lategraduancy periods of patients gradually lengthened,and the photopic FERG,scotopic FERG,pRNFL,and ppVD values decreased at each postoperative time point.At the same time,the best corrected visual acuity(BCVA)of patients after surgery gradually decreased(P<0.05).Compared with that at 1 week after surgery,the BCVA of Group A(without whole-process blood glucose manage-ment)gradually increased at 1 month and 3 months after surgery but showed a downward trend at 1 year after sur-gery.The BCVA of Group B(with whole-process blood glucose management)gradually stabilized at 1 month after surgery,and at all time points after surgery,the BCVA of Group B was better than that of Group A.The results showed that N75 and P100 in Group A were greater than those in Group B,while the photopic and scotopic FERG,pRNFL,and ppVD(%)in Group A were lower than those in Group B.In addition,N75 and P100 in Group A showed a gradual prolongation trend at various time points after surgery,while photopic FERG,scotopic FERG,pRNFL,and ppVD(%)showed a gradually decreasing trend.However,the above data in Group B gradu-ally stabilized at 3 months after DC surgery,approaching the preoperative level of the group(P<0.05).In the state of whole blood glucose management,although N75 and P100 both reached their longest durations at 1 week af-ter surgery,N75,P100,photopic FERG,scotopic FERG,and pRNFL showed a gradually decreasing trend at 1 month and 3 months after surgery,while ppVD(%)gradually increased(P<0.05).At various time points from 3 months to 1 year after surgery,the overall trend of the above indicators remained stable and close to the preoperative values(P>0.05).Conclusion According to the results of the quantitative analysis of visual electrophysiology and OCTA,in DC patients without obvious retinopathy and with the worsening of diabetes,retinal function decreased,but whole-process blood glucose management effectively restored retinal function and improved visual quality after surgery.
