Objective To investigate the role of activities of sympathetic nerve in the pathogenesis of shoulder-hand syndrome (SHS) by analyzing the hand sympathetic skin response (SSR) at the acute stage of SHS after stroke. Methods 50 stroke patients with SHS at the acute stage were assigned as SHS group, another 50 stroke patients without SHS as control group (N-SHS group) and 50 health volunteers as health group. Every patient was subjected to the detection of bilateral hand SSR. Results The detection rates of SSR in the SHS group and N-SHS group were significantly lower than that in the Health group (P<0.01). In comparison within the SHS group, the amplitude of SSR on the affected hand was apparently higher than on the healthy hand (P < 0.05), but there was no significant difference in the SSR latencies in both hands ( P > 0 . 05 ) . In comparison with the health group , bilateral SSR latencies of the SHS group were longer than those of the health group (P<0.05) and bilateral SSR amplitudes were all lower than those of the health group (P<0.01). Conclusions The bilateral hand sympathetic skin responses could change at the acute stage of SHS after stroke, with possible presentations of central inhibition of sympathetic activity. The abnormality of SSR may be an early warning indicator in patients with hemiplegia after stroke complicated with SHS.

Objective To investigate the correlation of endothelial function variation with pulse pressure index in Uygur acute coronary syndrome patients in Xinjiang. Methods Uygur patients were divided into acute coronary syndrome group (n=208) and control group (n=157) according to their Coronary angiography results. Height, weight and blood pressure were measured on admission and basic medical history were recorded. Fasting blood glucose (FBG), three acyl glycerin (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) were ex-amined using fasting venous blood;Plasma Coagulation FactorⅧ(CFⅧ) and von Willebrand factor(vWF)were examined using ELISA. Results There are no statistical difference in age, gender, history of hypertension, diabetes history, history of smoking, drinking, body mass index, PPI, HDL-C and FBG between two groups. The systolic pressure, diastolic blood pres-sure, pulse pressure, TG, TC, LDL-C and vWF, CFⅧlevels in acute coronary syndrome group were higher than those in the control group (all P<0.05). The levels of plasma vWF and CFⅧwere positively correlated with pulse pressure and PPI, it also was positively correlated between the levels of plasma vWF and CFⅧ(P<0.01). Conclusion The endothelial func-tion was significantly impaired in Xinjiang Uygur patients with acute coronary syndromes, and vascular endothelial damage was positively correlated with pulse pressure and PPI. The pulse pressure and PPI can be used to evaluate the vascular endo-thelial function indirectly.

Tourette syndrome is a childhood-onset disorder characterized by a combination of motor and vocal tics, often associated with psychiatric comorbidities including attention deficit and hyperactivity disorder and obsessive-compulsive disorder. Despite an onset early in life, half of patients may present symptoms in adulthood, with variable degrees of severity. In select cases, the syndrome may lead to significant physical and social impairment, and a worrisome risk for self injury. Evolving research has provided evidence supporting the idea that the pathophysiology of Tourette syndrome is directly related to a disrupted circuit involving the cortex and subcortical structures, including the basal ganglia, nucleus accumbens, and the amygdala. There has also been a notion that a dysfunctional group of neurons in the putamen contributes to an abnormal facilitation of competing motor responses in basal ganglia structures ultimately underpinning the generation of tics. Surgical therapies for Tourette syndrome have been reserved for a small group of patients not responding to behavioral and pharmacological therapies, and these therapies have been directed at modulating the underlying pathophysiology. Lesion therapy as well as deep brain stimulation has been observed to suppress tics in at least some of these cases. In this article, we will review the clinical aspects of Tourette syndrome, as well as the evolution of surgical approaches and we will discuss the evidence and clinical responses to deep brain stimulation in various brain targets. We will also discuss ongoing research and future directions as well as approaches for open, scheduled and closed loop feedback-driven electrical stimulation for the treatment of Tourette syndrome.

The diagnosis of post-stroke cognitive impairment (PSCI) mainly depends on clinical manifestation and scale assessment now, but lacks specificity. Studies in recent years have shown that there are biomarkers closely related to PSCI. This article reviews the blood biomarkers of PSCI.

COVID-19 is a public health emergency currently. In this study, a scale-free network model is established based on the Spring Migration data in 2020.The cities is clustered into three different modules. The epidemic of the cities in the black module was the most serious, followed by the red and the cyan. The black module contains 9 cities in Zhejiang province and 8 cities in Guangdong province, most of them located in the southeast coastal economic belt. These cities should be the key cities for epidemic prevention and control.

Since the implementation of antiretroviral therapy (ART), it has achieved remarkable results in the field of HIV/AIDS treatment. However, when the treatment is applied to the population-level, the actual impact of ART on the HIV epidemic becomes a hot topic in the field. This paper will summarize the research on ART and HIV epidemic in recent years, and discuss the impact of ART on the trend of HIV epidemic, so as to provide scientific support and suggestions for the role of treatment is prevention.

Objective To explore the comparative application of phase and diaphragmatic navigation in three-dimensional magnetic resonance cholangiopancreatography(3D-MRCP)thin-layer scanning in elderly patients.Methods A total of 180 elderly patients were scanned by phase and diaphragmatic navigation via Siemens Aera1.5T superconducting MR scanner.The acquired images were reconstructed by 3D reconstruction.The anatomical structure,image quality and disease diagnosis were compared between the phase and diaphragmatic navigation groups.Results In liver of anatomy,the liver of primary bile duct,the superior,middle and inferior extrahepatic bile duct and the gallbladder could be well displayed,and the difference was not statistically significant between the two groups(P＞0.05).The display of pancreatic duct and the liver of secondary bile duct of diaphragmatic navigation was significantly better than those of phase navigation(P＜0.05).In terms of image quality,the excellent rate of diaphragmatic navigation was significantly higher than that of phase navigation,and the difference was statistically significant(P＜0.05).There were no statistically significant differences in the detection rate of pancreatobiliary system diseases,the diagnostic rate of cholelithiasis,common bile duct stones,common bile duct dilatation and pancreatic duct dilatation between the two groups(P＞0.05).Conclusion Diaphragmatic navigation is signifi-cantly better than phase navigation in the display of the anatomical structure of the pancreatic duct,the liver of secondary bile duct,and the excellent rate of image quality.Diaphragmatic navigation is more suitable for thin-layer 3D-MRCP scanning in elderly patients.

A retrospective analysis was performed on one case of adult-onset type Ⅱcitrullinemia(CTLN2)caused by homozygous mutations of SLC25A13 genes.The patient,a 28-year-old male,had repeated limb convulsions for more than 4 years and worsened for 2 months.He usually liked to eat peanuts and meat.The brain MRI examination showed no abnormality,and anti-epileptic treatment was not effective.Further examination of blood aminotransferase,blood ammonia and citrulline were elevated,genetic testing showed that the SLC25A13 gene c.851_854del homozygous pathogenic mutation,the diagnosis was CTLN2,and the treatment was treated with a high-protein,high-fat,low-sugar diet and arginine,and there were no seizures followed up for half a year.Patients with recurrent seizures with special dietary preferences should be paid attention to the possibility of CTLN2,and genetic testing plays an important role in the diagnosis of CTLN2 and provides a basis for clinical diagnosis and treatment.
