Objective:To investigate the correlation between white matter hyperintensities (WMHs) and stroke etiology classification in patients with acute isolated penetrating artery territory infarction.Methods:Patients with first-ever acute isolated penetrating artery territory infarction admitted to the Department of Neurology, the Affiliated Hospital of Xuzhou Medical University from January 2017 to May 2020 were enrolled retrospectively. According to the Chinese Ischemic Stroke Subclassification (CISS) system, they were divided into large artery atherosclerosis (LAA) and perforating artery disease (PAD). According to the distribution of infarcts, they were divided into lenticulostriate artery (LSA) territory infarction and paramedian pontine artery (PPA) territory infarction. The demographics, vascular risk factors, baseline clinical data, WMHs location, and Fazekas Scale scores were documented. Multivariate logistic regression analysis was used to identify the independent influencing factors of stroke etiology classification. Results:A total of 440 patients with acute isolated penetrating artery territory infarction were enrolled, including 120 (27.3%) in the LAA group, and 320 (72.7%) in the PAD group; 213 (48.4%) with LSA territory infarction, and 227 (51.6%) with PPA territory infarction. The proportion of patients with total Fazekas score 3-6 and periventricular WMHs (PWMHs) score 2-3 in the PAD group was significantly higher than those in the LAA group (all P<0.05). In patients with LSA territory infarction, the proportion of the patients with hypertension, WMHs total Fazekas score 3-6 and PWMHs score 2-3 in PAD subgroup was significantly higher than those in the LAA subgroup, while the proportion of the patients with hyperlipidemia was significantly lower than that in LAA subgroup (all P<0.05). In patients with PPA territory infarction, the levels of low-density lipoprotein cholesterol and homocysteine in the PAD subgroup were significantly lower than those in the LAA subgroup. Multivariate logistic regression analysis showed that PWMHs score 2-3 was an independent correlation factor of PAD (odds ratio [ OR] 2.220, 95% confidence interval [ CI] 1.085-4.541; P=0.029). In patients with LSA territory infarction, hyperlipidemia was independently correlated with LAA ( OR 0.432, 95% CI 0.192-0.972; P=0.042), and PWMHs score 2-3 was independently correlated with PAD ( OR 3.846, 95% CI 1.193-12.397; P=0.024). In patients with PPA territory infarction, higher low-density lipoprotein cholesterol ( OR 0.660, 95% CI 0.494-0.883; P=0.005), homocysteine ( OR 0.958, 95% CI 0.930-0.987; P=0.005) and C-reactive protein ( OR 0.987, 95% CI 0.977-0.997; P=0.008) were independently correlated with LAA. Conclusions:WMHs are common in patients with acute isolated perforating territory infarction caused by LAA and PAD, and more severe PWMHs suggest that PAD is more likely to be the cause of the acute isolated perforating territory infarction, especially in patients with LSA territory infarction.

AIM:To observed the protective effect of diminazene aceturate(DIZE),an angiotensin-converting enzyme 2(ACE2)activator,on rats with diabetic cardiomyopathy(DCM).METHODS:Male Wistar rats(n=30)were randomly divided into normal control group ,DCM group and DIZE treatment group(DIZE group).The rats in DCM group and DIZE group were intraperitoneally injected with streptozotocin(65 mg/kg )to establish diabetic model.After 12 weeks,the diabetic rats were infused with DIZE at 15 mg· kg-1 · d-1 or the same volume of saline for 4 weeks using os-motic minipump.The cardiac function was measured at the end of the 16th week.The methods of Mason staining and HE staining were used to observe the morphological changes of the myocardial tissue.Western blot ,ELISA and immunohisto-chemistry were used to observe the changes of ACE2,angiotensin(Ang)Ⅱ,Ang-(1-7),interleukin(IL)-1,IL-6 and connective tissue growth factor(CTGF).RESULTS:DIZE significantly improved the expression of ACE 2 in diabetic rats(P<0.05).Compared with DCM group,the levels of IL-1 and IL-6 in DIZE group were significantly decreased ,and the cardiac function in DIZE group was significantly improved(P<0.05).CONCLUSION:ACE2 endogenous agonist DIZE significantly increases the ACE 2 level and reduces the level of inflammation ,thus protecting the heart function of DCM rats.

Complete healing of the intestinal mucosa is the most ideal goal in the treatment of inflammatory bowel disease (IBD). The intestinal mucosa healing not only significantly alters the course of the disease and relieves clinical symptoms, but also markedly reduces the occurrence of complications and prevents recurrence of IBD. As chronic inflammation associated with peptic ulcer damage is the main pathological feature of IBD, clinical treatment is mainly based on anti-inflammatory therapy, but such therapy cannot promote the healing of the intestinal mucosa of patients. Therefore, how to achieve long-term remission of IBD is still an urgent challenge. In the process of intestinal mucosal repair, the polarization of macrophages maintains the homeostasis of the intestinal microenvironment, which is a representative process that promotes mucosal inflammatory-repair. It is a key part of initiating tissue regeneration that should not be underestimated. In this paper, we reviewed the literature of the past decade, focusing on the promotion of intestinal mucosal healing in IBD. The discussion will highlight the importance and feasibility of regulating macrophages to promote intestinal mucosal repair. Following this thought, we discuss the shortcomings of current clinical treatments and summarize the relevant drugs which have potential to promote intestinal mucosal repair. The aim is to provide effective potential drugs and therapeutic targets for the treatment of IBD.

To study relevant risk factors of Shenmai injection induced adverse reactions by using Logistic model and ROC curve, and made the prediction for the occurrence of relevant adverse reactions/events. Case data of patients treated with Shenmai injection were collected by using the prospective, multi-center, large-sample, nested-case control method, in order to analyze the risk factors of Shenmai injection-induced adverse reactions/events, establish the logistic model and draw the receiver operating characteristic (ROC) curve for risk factors. During the study, 7632 patients (including 3 477 males and 4 155 females) were included, and eight of them suffered adverse reactions/events. Based on a multi-factor Logistic model analysis, the age (> or = 50 years) (OR = 5.061, 95% CI: 2.197-7.924; P = 0.001), the total number of medication days (OR = -1.020, 95% CI: -l.652 - 0.388; P = 0.002) and the single dose (OR = 0.245, 95% CI: 0.127-0.364; P = 0.000) were significant independent risk factors for Shenmai injection-induced adverse reactions/events. According to the results, ROC curves were drawn with age (> or = 50 years), the total number of days of inedication and single dose; The area under ROC curves the joint predictor (0.9753, 95% CI: 0.9443-1.000, P < 0.005) was larger than that of the other three single indexes, with a higher risk prediction value. The independent risk factors for Shenmai injection-induced adverse reactions/events included the age (> or = 50 years), the total number of days of medication and single dose. In clinical practice, the age (> or = 50 years), the total number of days of medication and the medication dose can be substituted in the joint predictor calculation formula (P = 1 / [1 + e(-(-21.58 + 5.061 x Xage - 1.020 x Xd + 0.245 x X(mL)] to predict the potential adverse reactions of patients and adjust the dosage regimen.

OBJECTIVETo summarize the experience of radical retropubic prostatectomy (RRP) and the multi-factors which influence on the prognosis and long life quality.

METHODSFrom January 1993 to March 2005, 132 cases radical retropubic prostatectomy were performed. The patients were divided into 2 groups: the early group and recent group. Eleven items in peri-operative time and follow up results were analysed. The erection function of 78 cases were investigated with international index of erectile function 5 score. In these patients, nocturnal electrobioimpedance volumetric assessment (NEVA) were observe in 19 cases.

RESULTSComparing of the 2 groups, the index connected with operative skill changed to optimization. No one died of prostate cancer in 63 follow up patients. Nine cases showed biochemical failure with criterion as prostate specific antigen > 0.4 microg/L. Fifty patients passed urine normal post-operation in 6 months. Eight patients had stress incontinence and 5 had entire incontinence at 6 month. Four patients had vesical neck stricture. Another follow up result shows 33 (58.9%) erection function recovered in 55 bilateral nerve-sparing operation and 7 recovered in 22 of unilateral nerve-sparing operation. NEVA shows 14 cases with artery supply insufficient in whom 4 regained erection function and 5 cases vein leakage in whom no one recovered.

CONCLUSIONSThe radical retropubic prostatectomy remains the procedure of choice for the cure of localized prostatic cancer. The keys for the operation are anatomic dissection, preservation of the neurovascular bundle and good skill. These are also important for a good life quality for the patients.

The iron and inflammation homeostasis are closely coupled, forming an integrated functional unit under physiological conditions. "Iron transport balance" has become the key mechanism to maintain iron homeostasis through bidirectional regulation of iron uptake and release and dynamic management of transmembrane concentration. It is also the physiological basis for the inflammatory balance between promotion and resolution. Under pathological conditions, represented by inflammatory bowel disease (IBD), disturbed iron transportation was highly involved in almost every step of inflammatory diseases. Therefore, the iron transporting rebalancing provides the mechanistic basis and effective approach for the normalization of inflammatory microenvironment. Macrophage is the key regulator of inflammation homeostasis and determinant for iron transport balance. Unfortunately, the current clinical transformation based on iron transport balance theory has still been insufficient. Sometimes, this strategy even showed high complexity and contradiction, severely restricting its clinical application. By summarizing the theoretical research progress of iron transport balance, especially its relevance to macrophage phenotypic polarization, this review aims to explore the therapeutic value in inflammation intervention by targeting iron transporting balance. This review will provide the necessary knowledge and hints for the research and development of candidate drugs in treating inflammatory diseases.

OBJECTIVETo understand HBV serotypes and genotypes epidemiology in a northern city and a southern city in China.

METHODSUsing polymerase chain reaction (PCR) and direct sequencing of HBV DNA PCR products, the serotypes and genotypes of HBV in 530 from HBsAg positive samples. The enrolled patients were from Harbin, a northern city and Lianjiang, a southern city in China.

RESULTSComparison of the serotypes and genotypes of HBV between Harbin and Lianjiang showed that adrq+ was the most predominant hepatitis B virus serotype in both Harbin and Lianjiang (87.2% and 73.5%,respectively), adw2 was the next (12.0% and 25.7%, respectively); genotype C was the most frequent in Harbin and Lianjiang (87.8% and 73.2%, respectively), and genotype B was the next (12.2% and 26.1%, respectively) only 1 patient was infected by genotype D, and 1 patient was found to be co-infected by genotype B and C in Lianjiang.

CONCLUSIONThe results suggest that the percentage of HBV serotypes and genotypes between Harbin and Lianjiang was significantly different (P less than 0.001), but the main HBV serotype and genotype of the two cities were similar.
