Aim To investigate the effect of simvastatin ( Sim ) on endogenous antioxidant system after acute myocardial infarction ( AMI ) and its potential mecha-nisms. Methods The acute myocardial infarction ( AMI ) rat models were made by ligation left anterior descending of coronary artery. Then the successful models were randomly divided into myocardial infarc-tion group ( MI group) and simvastatin group ( Sim,20 mg·kg-1·d-1), another group without ligation left anterior descending of coronary artery served as sham group(Sham group). The Sim group was administered simvastatin by gavage for 7 days. MI group and Sham group received saline. Hemodynamic parameters, lipid levels, troponinI ( c-TnI ) and lactate dehydrogenase ( LDH) concentrations were examined after 7days, and the levels of superoxide dismutase ( SOD) and glutathi-one peroxidase ( GP) of myocardial antioxidant system were detected by ELISA. The expression of cardiac p-Akt and p-eNOS protein were detected by Western blot. Results Acute myocardial infarction significant-ly lowered cardiac hemodynamic parameters, increased serum c-TnI and LDH levels, lowered levels of SOD and GP, and lowered the expression of p-Akt and p-eNOS protein. However, Sim could effectively prevent the deterioration of cardiac function, reduce serum c-TnI and LDH levels, increase levels of SOD and GP, and increase p-Akt and p-eNOS protein expression. Conclusion Early using Sim can effectively improve heart function after acute myocardial infarction, acti-vate myocardial antioxidant system,and reduce myocar-dial necrosis, which may be related to increasing the expression of p-Akt and p-eNOS.

Objective:To investigate the characteristics of magnetic resonance myelography (MRM) and its application in the treatment of spontaneous intracranial hypotension (SIH).Methods:The clinical data, MRM characteristics, and treatment of 15 patients with SIH who underwent MRM examination in the First Affiliated Hospital of Zhengzhou University from August 2014 to August 2019 were retrospectively analyzed. According to treatment methods, nine patients were divided into conservative treatment group and six patients were divided into combined epidural blood patch treatment group. The gender, age, time interval from onset to MRM examination, cerebrospinal fluid pressure and MRM characteristics between the two groups were compared. SPSS 20.0 software was used for statistical description, and independent sample t-test was applied to compare the differences between groups. Results:All of the 15 cases reported orthostatic headache. Their cerebrospinal fluid pressure was (29.67±19.77, range 0-55) mmH 2O (1 mmH 2O=0.009 8 kPa), and onset-MRM interval was (33.07±24.22, range 7-90) days. The MRM characteristics were observed, including all 15 cases with periradicular leaks, four cases with anterior epidural fluid collections, six cases with posterior epidural fluid collections, and eight cases with high cervical (C 1-2 to C 2-3) retrospinal cerebrospinal fluid collections. There were 2 to 32 leak sites with an average of (10.20±7.87) sites. Among the 153 leak sites, 58(37.9%) sites were located at cervical vertebra, 77(50.3%) sites at thoracic vertebra, 18(11.8%) sites at lumbar vertebra, and 61(39.9%) sites at either the cervicothoracic junction (C 7-T 1 to T 1-2) or the upper thoracic region (T 2-3to T 6-7). Five patients responded well to one-time targeted autologous epidural blood patch on the basis of the location of the cerebrospinal fluid leakage. Besides, one patient improved with targeted epidural blood patch twice. There were no statistically significant differences in gender, age, onset-MRM interval, cerebrospinal fluid pressure, number and location of leak sites between the conservative treatment group and combined treatment group. Conclusions:The periradicular leaks of cerebrospinal fluid at cervical vertebra and thoracic vertebra are the most common feature of MRM in patients with SIH. MRM can identify the existence and location of cerebrospinal fluid leakage, assist in the diagnosis of SIH, and guide targeted epidural blood patch.

Objective:To investigate the clinical characteristics and therapeutic efficacy of spontaneous intracranial hypotension (SIH) complicated with cerebral venous thrombosis (CVT).Methods:The clinical data of 4 patients with SIH complicated with CVT admitted to our hospital from March 2014 to April 2020 were retrospectively analyzed. And the clinical data of 35 patients with SIH complicated with CVT were included for summary analysis through literature retrieval (the databases included PubMed, CNKI and Wanfang; retrieval period was from database construction to December 31, 2020).Results:These 4 patients were with onset of orthostatic headache; one was with recurred orthostatic headache after relief, and the other 3 developed persistent headache and epileptic seizure; case 1 was with superior sagittal sinus and cortical vein thrombosis, case 3 was with superior sagittal sinus thrombosis, and other 2 patients were with isolated cortical vein thrombosis. Twenty-six documented cases demonstrated headache changes: 12 patients (46.15%) developed persistent headache, 12 patients (46.15%) showed orthostatic headache persistently, and 2 patients (7.69%) had disappeared headache. The most common new symptoms were epilepsy in 17 patients (48.57%) and limb weakness in 10 patients (28.57%). Totally, these 31 patients (4 patients from our hospital+27 patients from literature retrieval) had hemorrhage after treatment; the percentage of patients having hemorrhage changes in the 17 patients accepted anticoagulant therapy was significantly increased as compared with that in 14 patients accepted other treatments (7/17 vs. 1/14, P<0.05); there were no bleeding changes in 5 patients accepted epidural blood patch and anticoagulant therapy. Conclusions:The clinical features of SIH complicated with CVT are various, and the change of headache is not a reliable marker. In the course of SIH, it is necessary to be alert to the occurrence of CVT if there are new symptoms such as epileptic attack or limb weakness. The etiological treatment of SIH is essential and the hemorrhage risk after anticoagulant therapy should be concerned in patients with SIH complicated with CVT.

Objective:To explore the clinical characteristics of patients with antibodies against contactin-associated protein-like 2 (CASPR2).Methods:The clinical data of 24 patients with anti-CASPR2 encephalitis diagnosed at the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2022 were retrospectively analyzed. According to the age of first onset, the patients were divided into early onset group (10 cases, onset age<45 years) and late onset group (14 cases, onset age≥45 years). The clinical data including clinical manifestations, auxiliary examinations, and treatment response between these 2 groups were compared.Results:Among the 24 patients, there were 13 cases with epilepsy, 13 cases with cognitive decline, 13 cases with mental disorders, 14 cases with autonomic dysfunction, 8 cases with peripheral nerve hyperexcitability, 5 cases with Morvan syndrome, 5 cases with unstable walking, and 8 cases with sleep disorders. Among the 10 cases of the early onset group, 7 cases are females, and 8 cases showed epilepsy. The incidence rate of epilepsy in the early onset group was higher than that in the late onset group (5/14, Fisher exact probability, P=0.047). Among the 14 cases of the late onset group, 6 cases are females, 9 cases showed cognitive impairment and 8 cases presented with mental disorders. There were 6 cases with abnormal brain magnetic resonance imaging (MRI). The cerebrospinal fluid protein of the late onset group [0.37 (0.29, 0.58) g/L] was higher than that in the early onset group [0.22 (0.16, 0.30) g/L; Z=-2.667, P=0.008]. The modified Rankin Scale (mRS) scores before and after treatment were 3.29±0.83 and 1.50 (0.75, 2.25), which were higher than those in the early onset group [mRS scores before and after treatment were 2.10±0.99 and 0 (0, 1.00), t=-3.188, P=0.004; Z=-2.335, P=0.020]. Conclusions:There are various symptoms in patients with anti-CASPR2 encephalitis. The early onset patients are common in women, with a higher incidence of epilepsy. The late onset patients are common in males, with prominent manifestations of cognitive impairment and mental disorders, which have a greater impact on daily living abilities. And abnormal MRI findings are common, and the cerebrospinal fluid protein is higher in late onset patients. Anti-CASPR2 antibody may cause more severe immune damage to the nervous system in elderly patients.

Objective:To analyze the clinical and imaging features of patients with spontaneous intracranial hypotension (SIH) combined with vestibulocochlear nerve symptoms, and explore the mechanism of vestibulocochlear nerve damage.Methods:From January 2014 to September 2019, 72 patients with SIH were chosen in our hospital; their clinical data were retrospectively analyzed; all patients underwent brain MR imaging. Based on vestibulocochlear nerve symptoms including dizziness, vertigo, tinnitus, aural fullness, and hearing loss, these patients were divided into two groups: 27 patients with vestibulocochlear nerve symptoms and 45 patients without vestibulocochlear nerve symptoms. The clinical and brain MR imaging features were compared between the two groups. The quantitative indexes of brain MR imaging were measured including the height of the pituitary gland, distances of the suprasellar cistern and prepontine cistern, distance from optic chiasm to pituitary fossa, mamillopontine distance, pontomesencephalic angle, and angle of transverse sinus. The qualitative signs of brain MR imaging were evaluated including pachymeningeal enhancement, subdural effusion or hematoma, effaced suprasellar cistern and prepontine cistern, decreased mamillopontine distance and pontomesencephalic angle, and transverse sinus distention.Results:In 27 SIH patients with vestibulocochlear nerve symptoms, the mean CSF pressure was (37.50±27.54) mmH 2O, and 22 patients (91.7%) presented with orthostatic headache. In 45 SIH patients without vestibulocochlear nerve symptoms, the mean CSF pressure was (39.00±26.91) mmH 2O, and 39 patients (95.1%) presented with orthostatic headache. As compared with SIH patients without vestibulocochlear nerve symptoms, the patients with vestibulocochlear nerve symptoms showed significantly lower height of the pituitary gland ( P<0.05). The positive rate of effaced suprasellar cistern in SIH patients with vestibulocochlear nerve symptoms was significantly decreased as compared with those without vestibulocochlear nerve symptoms ( P<0.05); there were no significant differences in other quantitative indexes and positive rates of qualitative signs between the two groups ( P>0.05). Conclusion:The decrease of pituitary height and effaced suprasellar cistern may be closely related to the pathogenesis of vestibulocochlear nerve symptoms in SIH patients.

Objective:To analyze the epidemiological trends and major risk attribution of pancreatic cancer in China, Japan and South Korea from 1990 to 2019.Methods:The descriptive epidemiological method was conducted. The overall incidence rate, mortality rate, age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of pancreatic cancer in China, Japan and South Korea from 1990 to 2019 were collected from the Global Burden of Disease (GBD) Database. Age-standardized rates were calculated based on the worldwide standardized population structure provided by GBD Database 2019. Observation indicators: (1) incidence and motality of pancreatic cancer in China, Japan and South Korea in 2019; (2) age-period-cohort model analysis of incidence and mortality rates of pancreatic cancer in China, Japan and South Korea from 1990 to 2019; (3) trends of ASIR and ASMR of pancreatic cancer in China, Japan and South Korea from 1990 to 2019; (4) trends of major risk attribution of pancreatic cancer related death in China, Japan and South Korea from 1990 to 2019. Count data were represented as absolute numbers, percentages and ratios. Joinpoint V.4.7.0.0 software was used to calculate the annual percentage change (APC), the average annual percentage change (AAPC) of incidence and mortality rates of pancreatic cancer in different time periods and 95% confidence interval (95% CI). The age-period-cohort model in STATA V.15.0 software was used to analyze the influence of different ages, periods and birth cohorts on the risk of onset and death of pancreatic cancer after controlling the other two variables, with the risk effect size described as relative risk (95% CI). Results:(1) Incidence and motality of pancreatic cancer in China, Japan and South Korea in 2019. In 2019, the incidence rate of pancreatic cancer in China increased from 0.07/100,000 among 15-19 years old to 64.01/100,000 among 85-89 years old, with increasing from 0.09/100,000 to 94.71/100,000 in males and from 0.04/100,000 to 47.47/100,000 in females. The mortality rate of pancreatic cancer in China increased from 0.04/100,000 among 15-19 years old to 79.58/100,000 among 85-89 years old, with increasing from 0.05/100,000 to 116.50/100,000 in males and from 0.03/100,000 to 59.69/100,000 in females. The incidence rate of pancreatic cancer in Japan increased from 0.03/100,000 among 15-19 years old to 162.26/100,000 among 85-89 years old, with increasing from 0.03/100,000 to 177.67/100,000 in males and from 0.04/100,000 to 153.67/100,000 in females. The mortality rate of pancreatic cancer in Japan increased from 0.02/100,000 among 15-19 years old to 154.88/100,000 among 85-89 years old, with increasing from 0.02/100,000 to 170.93/100,000 in males and from 0.02/100,000 to 145.94/100,000 in females. The incidence rate of pancreatic cancer in South Korea increased from 0.04/100,000 among 15-19 years old to 136.78/100,000 among 85-89 years old, with increasing from 0.03/100,000 to 153.78/100,000 in males and from 0.04/100,000 to 129.73/100,000 in females. The mortality rate of pancreatic cancer in South Korea increased from 0.02/100,000 among 15-19 years old to 135.98/100,000 among 85-89 years old, with increasing from 0.02/100,000 to 156.21/100,000 in males and from 0.02/100,000 to 127.59/100,000 in females. The peak incidence and mortality of pancreatic cancer in China were found in males aged 65-69 years, and the overall incidence and mortality of males in different age groups were higher than those of females in the same age group. In Japan, the peak incidence of pancreatic cancer occurred in females aged 80-84 years and the peak mortality occurred in males aged 75-79 years. The morbidity and mortality of males aged <80 years were higher than those of females in the same age group, while the morbidity and mortality of males aged ≥80 years were lower than those of females in the same age group. In South Korea, the peak incidence of pancreatic cancer occurred in females aged 80-84 years, and the peak mortality occurred in males aged 70-74 years. The morbidity and mortality of males aged <75 years were higher than those of females in the same age group, while the morbidity and mortality of males aged ≥75 years were lower than those of females in the same age group. (2) Age-period-cohort model analysis of incidence and mortality rates of pancreatic cancer in China, Japan and South Korea from 1990 to 2019. Age effect: after adjustment for the period and cohort effects, the risk of incidence and mortality rates of pancreatic cancer in both males and females of China, Japan and South Korea increased with age, which is more obvious in females than males, and more obvious in Japanese than Chinese and Korean populations. Period effect: after adjustment for age and cohort effects, the risk of incidence and mortality rates of pancreatic cancer in both males and females of China, Japan and South Korea increased from 1990 to 2019, with the period effect more significant in the Chinese population. Cohort effect: after adjustment for age and period effects, the risk of morbidity and mortality rates of pancreatic cancer decreased with the passage of birth cohort in China, Japan and South Korea. (3) Trends of ASIR and ASMR of pancreatic cancer in China, Japan and South Korea from 1990 to 2019. The ASIR and ASMR of pancreatic cancer in China increased yearly from 1990 to 2019, and the ASIR and ASMR in 2019 were 1.82 times and 1.79 times those in 1990, respectively. The ASIR and ASMR of pancreatic cancer in Japan showed a slowly increasing trend, and the ASIR and ASMR in 2019 were 1.09 times and 1.05 times those in 1990, respectively. The ASIR and ASMR of pancreatic cancer in South Korea increased firstly, then decreased, and slowly increased. From 1990 to 2019, the AAPC of ASIR of pancreatic cancer in China was 2.08% (95% CI as 1.91% to 2.24%, P<0.05) and AAPC of ASMR was 2.02% (95% CI as 1.86% to 2.19%, P<0.05). The AAPC of ASIR of pancreatic cancer in Japan was 0.28% (95% CI as 0.15% to 0.42%, P<0.05) and AAPC of ASMR was 0.13% (95% CI as 0.03% to 0.24%, P<0.05). The AAPC of ASIR of pancreatic cancer in South Korea was 0.50% (95% CI as 0.21% to 0.80%, P<0.05) and AAPC of ASMR was 0.15% (95% CI as -0.10% to 0.40%, P>0.05). (4) Trends of major risk attribution of pancreatic cancer related death in China, Japan and South Korea from 1990 to 2019. The main risk factors for pancreatic cancer related death in China, Japan and South Korea from 1990 to 2019 were smoking, high fasting glucose and high body mass index (BMI). The trend of pancreatic cancer related death, mainly attributed to smoking, showed that the proportion of Chinese males increased from 31.4% in 1990 to 34.1% in 2000, then decreased to 31.1% in 2015, and then showed a slow increase to 31.7% in 2019. The proportion of Chinese females increased from 6.7% in 1990 to 10.4% in 2005 and then dropped to 8.7% in 2019. The proportion of Japanese males decreased from 38.8% in 1990 to 26.9% in 2019 and the proportion of Japanese females decreased from 20.9% in 1990 to 14.8% in 2019. The proportion of South Korean males decreased from 37.5% in 1990 to 30.3% in 2019 and the proportion of South Korean females decreased from 12.6% in 1990 to 10.0% in 2019. The trend of pancreatic cancer related death proportion, mainly attributed to high fasting blood glucose, showed that the proportion of Chinese males increased from 5.9% in 1990 to 7.1% in 2019 and the propor-tion of Chinese females increased from 6.2% in 1990 to 6.8% in 2019. The proportion of Japanese males increased from 7.0% in 1990 to 7.7% in 2019 and the proportion of females increased from 5.0% in 1990 to 5.5% in 2019. The proportion of South Korean males increased from 6.8% in 1990 to 9.7% in 2019 and the proportion of females increased from 6.1% in 1990 to 8.2% in 2019. The trend of pancreatic cancer related deaths proportion, attributed mainly to high BMI, showed that the proportion of Chinese males increased from 1.3% in 1990 to 3.0% in 2019 and the proportion of females increased from 2.1% in 1990 to 4.3% in 2019. The proportion of Japanese males increased from 2.0% in 1990 to 2.4% in 2019 and the proportion of females increased from 3.1% in 1990 to 3.4% in 2019. The proportion of South Korean males increased from 1.9% in 1990 to 3.1% in 2019 and the proportion of females increased from 3.4% in 1990 to 4.3% in 2019. Conclusions:The incidence of pancreatic cancer in China may continue to rise but to be stable in Japan and South Korea. The incidence of pancreatic cancer in females, especially elderly women, needs more attention. Smoking remains the most critical risk factor for pancreatic cancer. More attention should also be paid to the increased risk of pancreatic cancer associated with high BMI and high fasting plasma glucose.

【Objective】 To investigate the therapeutic effect of Huaier on acute pancreatitis (AP) and its potential mechanism. 【Methods】 A mouse model of cerulean-induced AP was used to verify the therapeutic effect of Huaier in vivo. HE staining and immunohistochemical staining were used to evaluate the histopathological changes of the pancreas, and transmission electron microscopy was used to observe the pyroptosis morphology of the pancreas. In vitro, 266-6 cell line was used as the experimental carrier to verify the protective effect of Huaier on acinar cells. Electron microscopy and Western blotting were used to evaluate the pyroptosis level of acinar cells, and ROS fluorescence probe was used to detect the oxidative stress state of acinar cells. 【Results】 Huaier significantly alleviated the severity of AP in mice. HE staining of pancreas showed that necrosis and inflammatory cell infiltration were reduced, and the level of serum amylase was decreased. Immunohistochemical staining and Western blotting showed that Huaier effectively inhibited the expressions of pyroptosis-related molecules such as NLRP3 and GSDMD in pancreatic tissue. Electron microscopy showed that Huaier could reduce the pyroptosis level of pancreatic acinar cells under inflammatory state. In addition, the level of ROS in acinar cells was significantly reduced after the intervention of Huaier, and ROS-mediated pyroptosis of acinar cells could be effectively inhibited by Huaier. 【Conclusion】 Huaier can effectively reduce the severity of AP by inhibiting ROS-mediated pyroptosis of acinar cells.
