Objective To investigate the relationship between plasma low-density lipoprotein (LDL) levels and hematoma enlargement of early intracerebral hemorrhage,outcome at 3 months and death.Methods A total of 316 patients with primary intracerebral hemorrhage were included in the study.Their general information was documented.The patients underwent CT scans at 6 and 24 hours after onset.The lipids,blood glucose,blood pressure,and the National Institutes of Health Stroke Scale (NIHSS) scores were detected at the same time.The patients were followed up for 3 months and their modified Rankin scale (mRS) scores and the number of death were recorded.Results The decreased plasma LDL level (odds ratio [OR] 0.323,95％ confidence interval [CI] 0.128 - 0.819; P =0.017) and the increased systolic pressure (OR 1.015,95％ CI 1.000 -1.029; P =0.043) were independently associated with the early hematoma enlargement.The decreased plasma LDL level (OR 0.253,95％ CI 0.102-0.629; P=0.003) and the increased blood glucose (OR 1.458,95％ CI 1.257 - 1.693; P ＜ 0.001 ) were the independent risk factors for poor outcome at 3 months after onset.The decreased plasma LDL level (OR 0.211,95％ CI 0.075 - 0.597; P =0.003),the increased bloot glucose level (OR 1.406,95％ CI 1.212 - 1.632; P =0.001) and the increased blood glucose level (OR 1.026,95％ CI 1.009 - 1.043; P =0.002) were the independent risk factors for death within 3 months.Receiver operating characteristic curves showed that the LDL level ＜ 2.58 mmol/L was an independent predictor for hematoma enlargement (sensitivity 71.79％,specificity 64.71％,positive predictive value 40.00％,and negative predictive value 87.50％ ).Conclusion The decreased plasma LDL level was the independent predictor for early hematoma enlargement,poor outcome and death at 3 months in patients with primary intracerebral hemorrhage.

Abstract: Objective　To analyze the vaccination status of SARS-CoV-2 in children, and explore the relationship between SARS-CoV-2 vaccination and COVID-19 in children. Methods　A retrospective study was conducted to analyze the clinical data of 335 cases of SARS-CoV-2 Omicron variant infection from February 15, 2022 to March 18, 2022 in Shenzhen Third People's Hospital. Results　Among 335 children with SARS-CoV-2 infection, 174(51.9%) cases were vaccinated with the SARS-CoV-2 vaccine; 33(31.4%) cases were vaccinated in the 3-<6 years old group; 141(61.3%) cases were vaccinated in the 6-<14 years old group. There was a statistically significant difference in the proportion of SARS-CoV-2 vaccination between the 6-<14 years old group and the 3-<6 years old group (χ2=26.1, P<0.05). In the study cohort, 3-<6 years old group and 6-<14 years old group, there was no significant difference in the incidence of COVID-19 in the vaccinated group compared with the unvaccinated group (P>0.05). In the study cohort, the proportion of confirmed cases of 1 dose of SARS-CoV-2 vaccine and 2 doses or more of SARS-CoV-2 vaccine was 89.5% (68 cases) and 77.6% (76 cases), respectively; in the 6~<14 years old group, the proportion of confirmed cases of 1 dose of SARS-CoV-2 vaccine and 2 doses or more of SARS-CoV-2 vaccine was 90.0% (54 cases) and 76.5% (62 cases), respectively; the differences were statistically significant (χ2=4.264, P<0.05; χ2=4.279，P<0.05). The IgG levels of 18.28 (6.61, 55.2) AU/mL and 58.3 (25.85, 131.41) AU/mL in the study cohort who were vaccinated for 1 dose, 2 doses and more, respectively; the IgG levels of 20.13 (8.33, 44.33) AU/mL and 56.57 (25.85, 150.07) AU/mL in the 6~<14 years old group who were vaccinated for 1 dose, 2 doses and more, respectively; and the differences were statistically significant (Z=-4.37, P<0.05; Z=-3.96, P<0.05). Conclusions　Children who received 2 doses of SARS-CoV-2 vaccine have a lower incidence of COVID-19 and higher levels of SARS-CoV-2 antibodies compared with who received 1 dose . It is recommended that children are advised to be vaccinated against the COVID-19.

Objective To investigate the influence of antiepileptic drugs (AEDs) on levels of serum homocysteine (Hcy),folate,vitamin B12 and B6 in patients with post-stroke epilepsy (PSE).Methods The serum levels of Hcy,folate,vitamin B12 and B6 of 194 PSE patients with AEDs treatment for more than 1 year (AEDs treatment group) and 40 newly diagnosed PSE patients without AEDs therapy (control group) were detected.The effects of AEDs on above indexes were analyzed.Results Compared with control group,the serum level of serum Hcy was significantly increased,and the serum levels of folate,B12 were significantly decreased in AEDs treatment group (all P<0.05).The difference of the serum levels of vitamin B6 among the groups was not significant.Compared with monothetapy subgroup,the serum levels of Hcy was significantly increased in the combination therapy subgroup (P<0.05).Compared with control group,the serum levels of Hcy were significantly increased in patients with Valproate (VPA),Carbamazepine (CBZ) and Oxcarbazepine (OXC) monotherapy,the serum levels of folate were significantly decreased in patients with VPA and CBZ monotherapy,and the serum level of B12 was significantly decreased in patients with VPA monotherapy (all P<0.05).Compared with control group,the serum levels of Hcy were significantly increased in patients with 2 kinds of AEDs combination treatment [VPA+CBZ,VPA+Levetiracetam (LEV),VPA+OXC,CBZ+LEV] or ≥3 kinds of AEDs combination treatment,the serum levels of folate was significantly decreased in patients with 2 kinds of AEDs combination treatment (VPA+LEV,VPA+OXC,CBZ+LEV) or ≥3 kinds of AEDs combination treatment,the serum levels of B12 were siginificantly decreased in patients with 2 kinds of AEDs combination treatment (VPA+CBZ,VPA+OXC,CBZ+LEV) or ≥3 kinds of AEDs combination treatment (all P<0.05).The incidence of hyperhomocysteinemia (HHcy) in AEDs treatment group (36.6%) was significantly higher than that in control group (20.0%) (χ2=4.085,P=0.043).And the difference of HHcy incidence between the combination therapy subgroup (47.6%) and the control group was statistical significant (χ2=6.950,P=0.008).The difference of HHcy incidence between the monotherapy subgroup (33.6%) and the control group was not significant.The HHcy incidence of patients with VPA and CBZ monotherapy (40.5%;43.8%) were significantly higer than those in the control group (χ2=3.871,P=0.049;χ2=4.726,P=0.030).The differences of HHcy incidence between patients with OXC,LEV monotherapy (29.2%;22.9%) and the control group were not significant.Conclusions AEDs therapy has little influence on the serum levels of vitamin B6,while has great influence on the serum levels of Hcy,folate and vitamin B12.Combination treatment of AEDs and monotherapy of VPA,CBZ may increase the incidence of HHcy in PSE patients.

Objective To investigate the influence of vitamin B supplementation on the plasma total homocysteine (Hcy), serum folate, serum vitamin B12, serum vitamin B6, and clinical state of senile epilepsy.Methods A total of 132 senile epilepsy patients with hyperhomocysteinemia, who visited the Second Affiliated Hospital of Soochow University from January 2013 to July 2015, were enrolled into this study.Eighty-three patients who accepted the therapy of vitamin B supplementation (folate 2.5 mg/d, vitamin B6 10.0 mg/d, vitamin B12 1.5 mg/d) were selected as treatment group, and 49 patients with no vitamin B supplementation were selected as control group.All patients were followed-up for one year.The differences of serum Hcy, folate, vitamin B12, vitamin B6 and seizure frequency, MMSE scores, Hamilton Depression Rating Scale (HDMA) scores between the treatment and the control groups were compared.According to the concentration of serum Hcy, 132 patients were divided into two groups: 75 patients (46 patients in the treatment group and 29 patients in the control group) with mild hyperhomocysteinemia (Hcy: 15.0-29.9 μmol/L), 57 patients (37 patients in the treatment group and 20 patients in the control group) with moderate-severe hyperhomocysteinemia (Hcy≥30.0 μmol/L).The differences of serum Hcy, folate, vitamin B12, vitamin B6 and seizure frequency, MMSE scores, HDMA scores between the treatment and the control group in the mild hyperhomocysteinemia group and in the moderate-severe hyperhomocysteinemia group were compared.And the influence factors of Hcy were analyzed.Results Correlation analysis revealed that Hcy was positively correlated with age (r=0.269, P=0.002), and negatively correlated with folate (r=-0.222, P=0.010).Hcy was associated with smoking (χ2=7.363,P=0.007), hypertension (χ2=6.187,P=0.013), and two or more antiepileptic drugs polytherapy (χ2=4.708,P=0.030).After vitamin B supplementation in the group of moderate-severe hyperhomocysteinemia, serum Hcy concentration ((15.68±4.85) μmol/L in the treatment group vs (31.14±11.18) μmol/L in the control group, t=5.890, P<0.01), seizure frequency (4.85±2.78 vs 6.15±1.95, t=2.028, P=0.047) and HDMA scores (15.22±7.55 vs 17.70±4.90, t=2.862, P=0.005) decreased, whereas serum folate ((9.08±3.33) ng/ml vs (5.87±2.91) ng/ml, t=3.618, P=0.001), vitamin B12 ((556.39±276.76) pg/ml vs (419.71±164.53) pg/ml, t=2.336, P=0.023), vitamin B6 ((22.94±5.59) μmol/L vs (21.09±4.87) μmol/L, t=2.029, P=0.047) and MMSE scores (26.89±1.94 vs 25.75±2.20, t=2.024,P=0.048) increased in the treatment group compared with the control group.While in the group of mild hyperhomocysteinemia, the differences of seizure frequency, HDMA and MMSE scores were not statistically significant between the treatment group and the control group (all P>0.05).Conclusions It is necessary to monitor serum Hcy for senile epilepsy.Vitamin B supplementation is a safe and inexpensive way to reduce the concentration of Hcy, assist to control seizures and improve the clinical symptom of depression and cognitive impairment for senile epilepsy with moderate-severe hyperhomocysteinemia.

Objective To explore the expression of merlin and cyclins and the nucleocytoplasmic shuttling of merlin in abiogenous vestibular schwannoma tissues. Methods Four paraffin imbedding vestibular Schwannoma samples were included in the study.The cyclins and merlin were analyzed by immunofluorescence at the same time,and the expression and location were synchronously observed with confocal laser microscopy(CLM) in a single schwannoma cell. Results Cyclins and merlin were perspicuously and synchronously presented in a single cell in vestibular schwannoma tissues.In early G1 phase of the tumor cell,merlin was mainly stained in the nucleus,followed by perinucleus and cytoplasm.In G1/S phase,merlin was concentrated in the perinucleus,less in the nucleus and cytoplasm.Merlin staining showed uniform distribution in the nucleus in G2/M phase,while was absent from the nucleus and concentrated in the perinucleus in late G2/M phase. Conclusion The expression of merlin and various kinds of cyclins can be synchronously presented in abiogenous vestibular schwannoma cells with immunofluorescence and CLM.Merlin is shuttling among the nucleus,cytoplasm and perinucleus along with the progression of cell cycle.
