Background:
and Purpose Essential tremor with a midline distribution (Mid-ET) may represent a distinct subtype of essential tremor (ET) that primarily affects midline structures, often indicating advanced disease stage and increased severity. Recent studies have highlighted the complexity of Mid-ET, but research on neurological soft signs (NSS) in Mid-ET remains insufficient.
Methods:
The patients with ET included in this cross-sectional study were divided into two subgroups based on whether or not the ET had a midline distribution: Mid-ET and No-MidET. Comparative analyses were performed to assess clinical features and NSS prevalence in these subgroups.
Results:
Among 1,160 patients, 567 (48.9%) were Mid-ET and 593 (51.1%) were No-Mid-ET.The prevalence rates of head, face (including the jaw), and voice tremors were 31.9%, 23.0%, and 25.8%, respectively. In Mid-ET, tremor often affects multiple midline structures simultaneously. In the entire cohort, 24.7%, 16.6%, and 7.6% of patients exhibited tremors in one, two, and three midline structures, respectively. The prevalence of common NSS, including mild cognitive impairment, impaired tandem gait, and questionable dystonic posturing, was significantly higher in the Mid-ET than the No-Mid-ET subgroup (all p<0.001). Furthermore, we found that female sex (p<0.001), olfactory dysfunction (p=0.003), and questionable dystonic posturing (p=0.004) were associated with Mid-ET.
Conclusions
Mid-ET and No-Mid-ET presented significant clinical differences. The presence of questionable dystonic posturing may contribute to the distinct characteristics of Mid-ET, suggesting the presence of pathophysiological differences between the subgroups. Further investigations are warranted to determine the potential pathophysiological link between NSS and Mid-ET.

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months, which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset,and rapid changes,which coincides with the characteristics of refractory angina which is complex and changeable,prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation, with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine (TCM) employs a holistic approach known as "activating blood circulation and removing toxins", which is supplemented by various methods to tonify Qi and warm Yang, nourish the kidneys and invigorate the spleen, clear heat and transform phlegm. This approach applies anti-inflammatory measures, regulates lipid metabolism, inhibits oxidative stress and thrombus formation, protects endothelial function in blood vessels, as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore,based on the theory of "stasis and toxin",combined with TCM theory and modern medical research,this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM,and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris,coronary microvascular dysfunction,coronary artery spasm and obstructive coronary artery disease,hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.

Atherosclerosis is a vascular disease characterized by arterial occlusion formed by the pathological accumulation of pathological vascular cells and apoptotic cell debris. Atherosclerotic vulnerable plaque is an important pathological basis for inducing severe thrombotic cardiovascular events, and the study of its etiology and pathogenesis has always been a hot issue in the field of cardiovascular research. Efferocytosis is a new type of programmed death cell removal, which refers to the process of macrophages phagocytosing and degrading apoptotic cells to prevent secondary necrosis. It is a key homeostatic mechanism in the body's physiological process. In the pathological state, the dysfunction of efferocytosis causes the pathological accumulation of apoptotic cells and necrotic debris, leading to the occurrence of secondary cell necrosis and the continuous release of intracellular toxic content and inducing inflammatory regression disorders and cholesterol metabolism disorders, which are closely related to the occurrence and development of atherosclerotic vulnerable plaques. The theory of ''blood stasis and toxin'' is an important theory of traditional Chinese medicine (TCM) to explain the occurrence and development of atherosclerosis. Atherosclerosis starts from the pathological state of blood stagnation. Prolonged blood stagnation leads to blood stasis and toxic substances. Blood stasis and toxic pathogens interact with each other in blood vessels and eventually form plaques in blood vessels. The theory of ''blood stasis and toxin causing a catastrophe'' is an important understanding of the occurrence and development of acute cardiovascular events. From the perspective of TCM theory, the pathophysiological mechanism of efferocytosis is similar to the etiology and pathogenesis of the ''blood stasis and toxin'' in TCM. Therefore, this paper took the theory of ''blood stasis and toxin'' as the breakthrough point to explore the mechanism of efferocytosis in atherosclerotic vulnerable plaques, and proposed a detoxification and blood circulation method to regulate cell burial to prevent and treat atherosclerotic vulnerable plaques. The research strategy aims to provide new ideas and theoretical basis for the prevention and treatment of atherosclerosis by detoxification and blood circulation.

Objective:To investigate the influences of SCN3A gene polymorphism(c.905A>G/p.N302S and c. 1441C>T/p.L481L) on the efficacy of valproic acid sodium in the treatment of Zhuangzu epilepsies.Methods:Using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP)technique and the way of direct sequence, the SCN3A gene c. 905A>G/p.N302S and c. 1441C>T/p.L481L genotypes in peripheral blood were detected in 244 epileptic patients (85 cases in effective group and 139 cases of ineffective group) in the standardized treatment of valproic acid sodium.The blood concentration of valproic acid sodium was detected by LC-MS.Evaluating the correlation between the genotype and alleles of two groups of patients and the efficacy of valproic acid sodium and analyzing the difference of valproic acid sodium's blood concentration between different genotypes.The linkage disequilibrium of c. 905A>G/p.N302S and c. 1441C>T/p.L481L were analyzed by software SHEsis.Results:The allele and genotype distribution in c. 905A>G/p.N302S loci between effective group(A, G allele: 50.6%, 49.4%, AA, AG, GG genotype: 27.1%, 47.1%, 25.8%) and ineffective group(A, G allele: 37.4%, 62.6%, AA, AG, GG genotype: 16.6%, 41.7%, 41.7%) had statistically significant difference(χ 2=7.501, P=0.006; χ 2=7.907, P=0.019). There was no significant difference in allele and genotype distribution of c. 1441C>T/p.L481L loci between effective group(C, T allele: 47.1%, 52.9%, CC, CT, TT genotype: 23.5%, 47.1%, 29.4%) and ineffective group(C, T allele: 38.8%, 61.2%, CC, CT, TT genotype: 18.7%, 40.3%, 41.0%)(χ 2=2.920, P=0.088; χ 2=3.099, P=0.212). Compared with the AA + AG genotype, the GG genotype at c. 905A>G/p.N302S locus significantly reduced the efficacy of valproic acid sodium ( OR=2.051, 95% CI=1.136-3.703). Compared with genotypes AA+ AG, there were no significant differences in blood concentration of genotype GG of c. 905A>G/p.N302S ( t=3.256, P=0.137). Compared with genotypes CC+ CT, there were no significant differences in blood concentration of genotype TT of c. 1441C>T/p.L481L( t=4.628, P=0.082). c.905A>G/p.N302S and c. 1441C>T/p.L481L were without linkage disequilibrium. Conclusion:These results suggest that the single nucleotide polymorphisms of c. 905A>G/p.N302S in SCN3A genes may play a role in the resistivity of valproic acid sodium in Zhuangzu epilepsies.

The acupuncture direction is closely related with the efficacy of acupuncture analgesia. In this article, the relationship between efficacy of acupuncture analgesia and factors, such as whether the needle towards disease location, whether the needle towards meridian direction, whether the needle following spinal cord direction and whether the needle following muscle direction, were analyzed. The previous clinical and literature research indicated that the needle towards disease location was superior to reverse direction, however, the efficacy of analgesia between needle following and reversing meridian, needle towards and at disease location, needles following and reversing spinal cord direction, needles following and reversing muscle direction was controversial. Therefore, the solutions to these problems will benefit the optimized acupuncture treatment plan for pain disorders.
