Objective:To explore the incidenee of early hematoma growth in patients with intracerebral hemorrhage,and the correlation between early hematoma growth and early neurological deterioration.Methods:The evaluation of nervous system and CT scan in patients with intracerebral hemorrhage within 3 hours after the omet of symptoms were performed respectively at baseline,and 1,2,3,and 20 hours after the baseline.Results:In 106 patients,CT scan shelwed that the volume of intraparenehymal hemorrhage inereased significantly in 26% of patients at baseline and within 1 hour.CT scan showed that the bleeding volume increased in 12% of patients at 1,2,3,and 20 hours.By measuring baseline,1-hour Glasgow Coma Scale (GCS)score,and the changes of the National Institutes of Health Stroke Scale(NIHSS),it had found that the baseline status and the increased bleeding volume within 1 hour vdgre closely correlated with the clinical neurological deterioration.Conclusions:The early bleeding volume often inereases significantly in patiems with intracerebral hemorrhage,which is complicated with neurological deterioration.In order to determine whether these therapeutic measures improve the natural course of this early hematoma growth and decrease its occurrence,it is necessary to make a randomized clinical trial.

This article was aimed to study the immunomodulatory effect of ethanol sediments of the seeds of Descurainia sophia(L.) Webb. ex Prantl. both in vitro and in vivo. The lymphocyte proliferation test in vitro was carried out to explore the effect of the ethanol sediments on the proliferation of T cell and B cell in the spleen of normal mice. And, the carbon clearance test, serum hemolysin test, and delayed-type hypersensitivity test were used to investigate the influence of fraction on non-specific immunity, humoral immunity and cellular immunity in the immunosuppressive mice induced by cyclophosphamide. Besides, the immunosuppressive model was used to evaluate the effect of fraction on immune organs and content of cellular factors in blood serum. The results showed that the ethanol sediments promoted Concanavalin A (Con A) induced T cell and Lipopolysaccharides (LPS) induced B cell (P < 0.01). It increased the carbon clearance index K, phagocytic index α, half value hemolysis (HC50), and swelling degree of auricula (P < 0.05 or P < 0.01). It reduced the body weight and atrophy of thymus and spleen index (P < 0.05 or P < 0.01). It increased the contents of IL-2, IFN-γ and IL-4 in serum in immunosuppressive mice (P < 0.05 or P < 0.01). It was concluded that ethanol sediments of the seeds of D. sophia(L.) Webb. ex Prantl. can boost the lymphocyte proliferation, protect the immune organs, and enhance the non-specific and specific immunity in immunosuppressive mice, which indicated that it had immune-promotion effect.

Objective To explore the correlation between Toll-like receptor(TLR)and nuclear factor-KB(NF-κB)levels in monocytes and type 2 diabetic autonomic neuropathy(T2DAN).Methods A total of 112 patients with type 2 diabetes mellitus(T2DM)admitted to the Puyang People's Hospital from April 2021 to December 2022 were selected as the observation group,and 50 healthy volunteers who underwent physical examination in the hospital during the same period were selected as the control group.Reverse transcription polymerase chain reaction(RT-PCR)was used to detect plasma TLR2,TLR4 and NF-κB levels in monocytes of patients in the two groups.According to the presence or absence of autonomic neuropathy,patients in the observation group were divided into the autonomic neuropathy group(n=46)and the non-autonomic neuropa-thy group(n=66),and clinical data of patients in these two groups were compared.Multivariate logistic regression analysis was used on indicators with statistically significant differences to determine the risk factors for T2DAN,and Spearman correlation analysis was used to evaluate the correlation between TLR2,TLR4 and NF-κB levels and T2DAN.Results The TLR2,TLR4 and NF-κB levels in monocytes of patients in the observation group were higher than those in the control group(P<0.05).Univariate analysis showed that there were significant differences in age,monocyte/high-density lipoprotein ratio(MHR),and levels of cystatin C,TLR2,TLR4 and NF-κB between the autonomic neuropathy group and the non-autonomic neuropathy group(P<0.05).Multivariate logistic regression analysis showed that MHR,TLR2,TLR4 and NF-κB levels were risk factors for autonomic neuropathy in T2DM patients(P<0.05).Spearman correlation analysis showed that TLR2,TLR4 and NF-κB levels were positively correlated with T2 DAN(r=0.825,0.822,0.819;P<0.05).Conclusion The expressions of TLR2,TLR4 and NF-κB are up-regulated in T2DM patients,and the expression levels of TLR2,TLR4 and NF-κB are correlated with autonomic neuropathy in T2DM patients.

Objective. To investigate the effects of coxsackievims B3 (CVB3) on ion channel currents in rat ventricular my-Methods. Rat hearts were isolated with collagenase to acquire single ventricular myocytes, L-type voltnge-depen-dent calcium channel( VDCC)current (Ica), Na + current (INa), outward potassium current (Iout), inwardly rectifying potassium current(IKI) were recorded using whole cell patch clamp techniques. Results. CVB3 infection increased Ica and Iout, while decreased IKI; but it had no obvious effect on INa. Conclusion. Tne effects of CVB3 on Ica、 Iout、 IKI may be one of the mechanisms of myocytes damage and the oc-currence of abnormal electroactivities induced by CVB3 infection.
