Transient receptor potential ankyrin 1 (TRPA1) is a family member of the transient receptor potential (TRPs). It is primarily localized to a subpopulation of primary sensory neurons, such as trigeminus, vagus and dorsal root ganglia. Neuropathic pain is often caused by peripheral nerve injury, diabetes and chemotherapeutics. A large of oxidative/nitrative stress products are produced during neuropathic pain, which cause acute nociception, allodynia, and hyperalgesia. TRPA1 antagonists may be beneficial in the treatment of neuropathic pain. Here, the role of TRPA1 in neuropathic pain is summarized.

From January 2000 to December 2006, 78 hypertensive patients with intracerebral hemorrhage(80~130 ml)underwent minimally invasive surgery(n=41)or small bone window craniotomy(n=37). Neurological deficit scores and mortality were estimated to evaluate the therapeutic efficacy among those two group patients. The success rate was significantly higher in the micro-invasive surgery group than the small bone window craniotomy group(P<0. 05). However, no significantly lower mortality was detected in the micro-invasive surgery group(P>0. 05). In summary, micro-invasive surgery may reduce the mortality, largely increase the success rate of treatment, and improve patients' quality of life.

Chinese Journal of Primary Medicine and Pharmacy 2020;27(9):1035-1039
Objective:To investigate the clinical effect of vortioxetine in the treatment of patients with first-episode depression.Methods:From January 2018 to January 2019, 100 patients with depression in outpatients or inpatients of Wenzhou Kangning Hospital were enrolled in the study.According to different treatment methods, they were divided into control group and observation group according to the random digital table method, with 50 cases in each group.The control group was given fluoxetine 20-40mg, qd, and the observation group was treated with vortioxetine.Both two groups were treated for 8 weeks.The pre-treatment subjective cognitive function of the two groups was evaluated.Brain-derived neurotrophic factor(BDNF), homocysteine (Hcy), tumor necrosis factorα(TNF-α), 1, 25-hydroxyl vitamin D 3[1, 25-(OH) 2D 3] were detected in two groups.The electrophysiological indicators event-related potential P300 were detected.The Hamilton Depression Scale(HAMD) was used to evaluate the mental anxiety, mood and physical anxiety of patients before and after treatment in the two groups.The clinical effects of the two groups were evaluated and the adverse reactions were recorded. Results:After treatment for 4 weeks and 8 weeks, the cognitive function scores of the control group were (24.96±2.85)points and (26.18±3.16)points, respectively, which of the observation group were (28.65±3.32)points and (32.66±3.81)points, respectively, which were significantly higher than before treatment(control group: F=14.821; observation group: F=10.632, all P<0.01). The cognitive function scores of the two groups after treatment for 8 weeks were significantly higher than treatment for 4 weeks (control group: t=2.027, P=0.045, observation group: t=5.611, P=0.000). After treatment, the levels of BDNF, Hcy, TNF-α, 1, 25-(OH) 2D 3 in the control group were (29.74±3.62)ng/L, (18.46±2.34)μmol/L, (314.11±15.87)ng/L, (30.69±4.17)ng/mL, respectively, which in the observation group were (34.22±2.85)ng/L, (14.55±2.17)μmol/L, (286.55±10.11)ng/L, (34.92±4.28)ng/m, respectively, the differences between the two groups were statistically significant( t=6.876, 8.663, 10.357, 5.005, all P<0.01). After treatment, the P300 latency and P300 amplitude of the control group were (426.94±4.72)ms, (0.62±-4.31)μV, respectively.which of the observation group were (413.65±3.66)ms, (0.84±-4.76)μV, respectively, the differences between the two groups were statistically significant( t=15.734, 3.048, all P<0.01). After treatment, the HAMD score of the observation group[(10.72±1.53) points] was significantly lower than that of the control group[(12.93±1.84)points]( t=6.530, P<0.01). The effective rate of the observation group was 88.0%(44/50), which of the control group was 86.0%(43/50), the difference between the two groups was not statistically significant( P>0.05). Conclusion:The application of vortioxetine in the treatment of patients with first-episode depression can improve the cognitive function and clinical symptoms of patients, and can also reduce the biochemical indicators of patients.However, the therapeutic effect is similar to that of fluoxetine, but it has less adverse reactions, so it is worthy of promoting.

Objective:To explore the related risk factors of secondary thoracotomy to stop bleeding after rheumatic heart disease valve replacement.Methods:A retrospective analysis of 373 patients in the Department of Cardiac Surgery of the First Hospital of Shanxi Medical University who underwent rheumatic heart disease valve replacement surgery from December 2013 to October 2020. According to whether or not to perform secondary thoracotomy to stop bleeding after operation, they were divided into two thoracotomy case group and control group. Collect the relevant clinical data of the patients, and analyze the risk factors that affect the second postoperative thoracotomy to stop bleeding through univariate and multivariate Logistic regression.Results:Among the 373 patients, 62 cases (16.62%) were in the secondary thoracotomy group and 311 cases (83.38%) were in the control group. Univariate analysis showed that the patient' s age, gender, prehospital cardiac function classification, pulmonary artery pressure, hemoglobin value (Hb), prothrombin time (PT), operation time, combined hypertension, intraoperative blood transfusion and postoperative two The occurrence of secondary thoracotomy to stop bleeding was related, and the difference was statistically significant ( P<0.05). The results of unconditional logistic regression analysis showed that prehospital cardiac function classification, Hb, PT, and hypertension are the risk factors leading to secondary thoracotomy to stop bleeding after rheumatic heart disease valve replacement. Conclusion:Effective control of risk factors can reduce the incidence of secondary thoracotomy after rheumatic heart disease valve replacement, and reduce the risk caused by secondary operations.

Objective To comprehensively consider the effect of low diverter (FD) implantation on aneurysmal sac and its branches, so as to provide references for making a more reasonable surgical strategy for intracranial aneurysm embolization in clinical practice. Methods Based on computational fluid dynamics (CFD) method, the FD implantation procedure was simulated by using porous media model innovatively. Changes in hemodynamic parameters of aneurysmal sac and side branch with different diameters before and after FD implantation were compared and analyzed, such as blood flow field, velocity, wall pressure and wall shear stress (WSS). Results FD changed the hemodynamic characteristics of aneurysms. The blood flow velocity decreased significantly. The WSS on aneurysmal neck increased, while the difference of WSS between proximal and distal cervical area reduced conversely. Different side branch diameters of vessels had different effects on hemodynamic characteristic changes. The larger diameter would cause the greater blood flow reduction in side branch after FD implantation, but the decrease in velocity of aneurysmal sac and pressure on aneurysmal roof became smaller simultaneously. Meanwhile, the increase of WSS on aneurysmal neck was inversely proportional to the diameter of side branch. Conclusions The larger branch diameter of vessels would cause the worse effect of FD embolization therapy for intracranial aneurysm, worse atherosclerosis improvements and greater possibilities of branch occlusion or other ischemic complications. Doctors should pay more attention to such cases in FD interventional intravascular embolization in clinic.
