ObjectiveTo observe the efficacy and safety of Uyghur medicine Yangxin Dawayimixike Honey Paste （养心达瓦依米西克蜜膏， YDMHP） in the treatment of stable angina pectoris （SAP） of qi stagnation and blood stasis syndrome. MethodsA randomized ， double-blind， positive-controlled，multi-center clinical trial was conducted， in which 370 patients with SAP of qi stagnation and blood stasis syndrome were randomly divided into treatment group（279 cases）and control group（91cases）at a ratio of 3∶1. The treatment group was orally administered with YDMHP， 3 g each time， and placebo of Xuefu Zhuyu Capsule （血府逐瘀胶囊）， 2.4 g each time， while the control group was treated with Xuefu Zhuyu Capsule， 2.4 g each time， and placebo of YDMHP， 3 g each time， both twice a day for a course of 12 weeks. The primary outcome was the effect of angina pectoris symptom. The secondary outcomes include single angina symptom scores such as number of attacks， duration of attacks， pain intensity and usae of nitroglycerin scores， the total angina symptom score before and after the treatment， the usage of nitroglycerin， the exercise duration in treadmill exercise test （TET） and the Duck treadmill score among patients，the scores of Seattle Angina Questionnaire （SAQ） on five dimensions including physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception， and efficacy of TCM syndrome and of each single TCM symptom after treatment. The safety were evaluated by examine blood routine， urine routine， liver and kidney function， fasting blood sugar， electrocardiogram， adverse events. ResultsThe total effective rate of angina symptom in the treatment group was 71.69% （200/279）， significantly higher than 51.64% （47/91） in the control group （P＜0.01）. The curative and markedly effective rate of TCM syndrome in the treatment group was 53.05% （148/279）， which was significantly higher than 25.27% （23/91） in the control group （P＜0.01）. After treatment， scores of the number as well as duration of angina attacks and pain severity， the total score of angina symptoms， and the usage of nitroglycerin significantly decreased in both groups， and more changes were seen in the treatment group than in the control group； the scores of physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception in both groups significantly increased， and more improvement were shown in the experimental group regarding the anginal stability， anginal frequency and treatment satisfaction （P＜0.05 or P＜0.01）. The effects of chest pain， chest tightness， palpitation， shortness of breath and fatigue in experimental group were significantly higher than those in control group （P＜0.05 or P＜0.01）. There was no significant difference in the exercise duration of treadmill test and Duke score among patients between the two groups either before or after treatment （P＞0.05）. Adverse events occurred in 66 cases （23.66%） of the experimental group and 16 cases （17.58%） of the control group， with no statistical significance between the two groups （P＞0.05）. ConclusionThe Uyghur medicine YDMHP can effectively improve symptoms of angina pectoris， reduce the number， duration， and intensity of attacks， decrease the dosage of nitrogly-cerin and improve the individual TCM symptoms and has good safety in the treatment of SAP patients of qi stagnation and blood stasis.

Background::Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.Methods::This multicenter, randomized, double-blind, placebo-controlled, phase 2b trial was conducted in 21 medical institutions in China from February to November 2021. Totally 120 eligible patients were enrolled and randomized (1:1:1) to receive subcutaneous injections of 300 mg CM310, 150 mg CM310, or placebo every 2 weeks for 16 weeks, followed by an 8-week follow-up period. The primary endpoint was the proportion of patients achieving ≥75% improvement in the Eczema Area and Severity Index (EASI-75) score from baseline at week 16. Safety and pharmacodynamics were also studied.Results::At week 16, the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups (70% [28/40] for high-dose and 65% [26/40] for low-dose) than that in the placebo group (20%[8/40]). The differences in EASI-75 response rate were 50% (high vs. placebo, 95% CI 31%–69%) and 45% (low vs. placebo, 95% CI 26%–64%), with both P values <0.0001. CM310 at both doses also significantly improved the EASI score, Investigator’s Global Assessment score, daily peak pruritus Numerical Rating Scale, AD-affected body surface area, and Dermatology Life Quality Index compared with placebo. CM310 treatment reduced levels of thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase, and blood eosinophils. The incidence of treatment-emergent adverse events (TEAEs) was similar among all three groups, with the most common TEAEs reported being upper respiratory tract infection, atopic dermatitis, hyperlipidemia, and hyperuricemia. No severe adverse events were deemed to be attributed to CM310. Conclusion::CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.Trial Registration::ClinicalTrials.gov, NCT04805411.

Conversion therapy has become the core in the treatment of borderline resectable or unresectable liver cancer, which provides resectable opportunities for more advanced liver cancer patients. In accordance with the first-choice treatment regimen recommended by the guidelines, the authors reported a successful case of Atezolizumab and Bevacizumab (T+A regimen) conversion therapy. The patient with initially borderline resectable advanced liver cancer was performed liver segment resection sucessfully after conversion therapy, and non-tumor recurrence was observed at postoperative 9 months. Postoperative pathological examination showed combined hepatocellular-cholangiocarcinoma, which also indicated the important value of T+A regimen in the conversion therapy of combined hepatocellular-cholangiocarcinoma.

Objective: To investigate the feasibility of one-step coronary and carotid-cerebrovascular computed tomography angiography (CTA) using high-pitch Double Turbo Flash mode and to analyze the image quality and radiation dose in patients with heart rate variability using multi-slice detector dual-source CT. Methods: A total of 79 patients with heart rate variability higher than 3 beat/min (bpm) were retrospectively analyzed. They were grouped by the scanning methods. Group A (n=40) were performed double turbo flash mode for one-step coronary and carotid-cerebrovascular arteriesinjected with one injection of contrast agent.further divided into Single A (only the phase 1 image)and Double A(combined images of phases 1 and 2). Group B (n=39) were performed separately with twice injection of contrast agent. Subjective scoring was performed on the image quality of the group Single A, Double A and B using a 4-point. Then the objective parameters of image quality, CT attenuations, image noise, signal-to-noise (SNR), and contrast-to-noise (CNR), were evaluated. Then subjective scores, objective evaluation indicators, and radiation dose were compared with one-way ANOVA analysis among the three groups.Contrast agent were compared by using t test in group A and B. Results: No significant difference was found (F=2.093, P=0.128) for the subjective scores of the head and neck CTA among the three groups with (3.47±0.51), (3.53±0.51), (3.69±0.47). Significant difference was found (F=50.955, P<0.01) for the subjective scores of coronary CTA among the three groups with (2.70±0.76), (3.35±0.66), (3.58±0.50), and there was no statistically significant difference between Double A and B groups (P=0.104), met the requirements for diagnosis. The objective evaluation of the three groups compared the head and neck CTA images were statistically significant (P<0.05), of which the difference between the Single A and the Double A was not statistically significant (P>0.05), met the requirements for diagnosis; the differences in SNR and CNR of coronary CTA images are statistically significant (F=12.991, 12.236, P<0.01), and there was no statistically significant difference between Double A and B (P>0.05), met the requirements for diagnosis. Radiation dose in the group Double A was lower than group B (decreased by 46.15%,P<0.01).The amount of the contrast agent in the group Double A was lower than group B (decreased by 44.13%, t=-45.455;P<0.01). Conclusion The double turbo flash mode is feasibility for one-step coronary and carotid-cerebrovascular CTA in patients with the heart rate variability using multi-slice dual-source CT.This scan mode can maintain the diagnostic image quality with low contrast agent and radiation dose.

Objective To explore the effect of electroacupuncture and transcutaneous electrical acupoint stimulation (TEAS) on somatosensory evoked potential (SEP) of the upper extremity in healthy subjects. Methods From October, 2015 to April, 2016, ten healthy young volunteers were selected. Each of the subjects was randomly treated with electroacupuncture and TEAS. Before and after treatment, the latency and amplitude of N20 and N9 of SEP were detected. Results After electroacupuncture, the latency of N20 prolonged in the stimulated side (Z=-2.620, P<0.01); the latency of N9 prolonged (Z=-2.454, P<0.05), and the amplitude of N9 decreased (Z=-2.330, P<0.05) in the non-stimulated side. After TEAS, the latencies of N9 both in the stimulated side and the non-stimulated side prolonged (Z>2.695, P<0.01). There was no significant difference in the D-value of latency and amplitude of N20 and N9 in both two sides between two treatments (Z<1.817, P>0.05). Conclusion Both electroacupuncture and TEAS could affect the latency and amplitude of N20 and N9, and no difference was found between two treatments.

Objective:To observe the influence of long-term exercise training on carotid intima-media thickness (IMT)in patients with mild-to-moderate hypertension.Methods:A total of 92 patients with mild-to-moderate es-sential hypertension (EH)were randomly and equally divided into exercise group and routine treatment group.Exer-cise group received exercise training based on routine treatment.All patients were followed up one year.Influence of long-term exercise training on carotid artery diameter and carotid IMT was observed in EH patients.Results:Af-ter one year,there were significant reductions in systolic blood pressure (SBP),diastolic blood pressure (DBP),ca-rotid artery diameter and carotid IMT in both groups,P<0.05 all;compared with routine treatment group,there were significant reductions in SBP [(145.72±11.31)mmHg vs.(130.89±13.01)mmHg],DBP [(88.49±7.32) mmHg vs.(81.71±8.45)mmHg],carotid artery diameter [(6.34±1.23)mm vs.(6.22±1.01)mm]and carotid IMT [(0.89±0.21)mm vs.(0.84±0.11)mm]in exercise group after treatment,P<0.05 all.Conclusion:Long-term exercise training can effectively reverse early arteriosclerosis lesion of carotid wall and effectively control blood pressure.

Objective To investigate the efficacy of concomitant precise hemihepateetomy for the treatment of hilar cholangiocarcinoma.Methods The clinical data of 38 patients with hilar cholangiocarcinoma who received concomitant precise hemihepatectomy at the First Affiliated Hospital of Xi'an Jiaotong University from January 2009 to October 2012 were retrospectively analyzed.All patients were examined by B ultrasonography,computed tomography (CT),magnetic resonance cholangiopancreatography (MRCP) and CT angiography (CTA)preoperatively.The hepatic function was tested before operation.Of the 7 patients with obstructive jaundice,5 received percutaneous transhepatic cholangial drainage,and 2 received endoscopic nosalbiliary drainage.Surgical procedures were determined according to the results of imaging examination.The resection of hilar cholangiocarcinoma,postoperative histopathological examination,pre-and postoperative hepatic function and prognostic indicators were analyzed.The count data and measurement data were analyzed using the chi-square test and t test,respectively; the survival curve was drawn by Kaplan-Meier method,and the survival rate was analyzed using the Log-rank test.COX proportion hazards model was used for multivariate analysis.Results The positive rates of B ultrasonography,CT and MRCP were 65.8％ (25/38),71.1％ (27/38) and 89.5％ (34/38),respectively.The results of 5 patients who received CTA were positive.Concomitant left hemihepatectomy was performed on 28 patients,concomitant right hemihepatectomy on 10 patients; concomitant caudate lobectomy on 22 patients,concomitant resection and reconstruction of portal vein on 4 patients (including 1 patient who received left hepatic vein repair),concomitant hepatic artery resection on 12 patients (including 3 patients who received hepatic artery reconstruction).Of the 38 patients,R0 resection was performed on 32 patients,R1 resection on 4 patients,R2 resection on 2 patients.Hepatic function indicators including total bilirubin,direct bilirubin,alkaline phosphatase,gamma-glutamyl-transferase,alanine aminotransferase and aspartate aminotransferase were significantly decreased after operation (t =7.799,8.445,5.697,6.633,4.469,4.140,P ＜ 0.05).Two patients died perioperatively,with the mortality rate of 5.3％ (2/38).The main postoperative complications included bile leakage and hepatic function insufficiency,with the incidences of 28.9％ (11/38) and 21.1％ (8/38),respectively.Postoperative histopathological findings included 31 patients with invasive adenocarcinoma,5 patients with nodular adenocarcinoma,1 patient with mucinous adenocarcinoma and 1 patient with adenosquamous carcinoma.The overall 1-,2-,3-year survival rates were 66％,37％ and 21％,and the median survival time was 22.0 months.There were significant differences in the survival rates between patients who received R0 resection and those with R1/R2 resection,and between patients with N0 and N1/N2 stage (x2 =4.516,10.397,P ＜ 0.05).The results of multivariate analysis showed that positive margin and lymph node metastasis were prognostic indicators.Conclusions Concomitant precise hemihepatectomy has significantly improved the radical resection rate and the efficacy of treatment for hilar cholangiocarcinoma.Comprehensive preoperative imaging examination and hepatic function test are important for the assessment for resectability of hilar cholangiocarcinoma.Selective preoperative biliary drainage are key points to decrease postoperative morbidity and morality.

Objective To summarize MRI findings of focal cortical dysplasia (FCD), analyze MRI characteristics of various pathological subtypes of focal cortical dysplasia. Methods Forty-four patients with FCD were collected. Their MRI findings were analyzed retrospectively. According to pathologic findings, these patients were divided into FCD type Ⅰ group and FCD type Ⅱ group. The following MR signs were observed in the two types of FCD: ( 1 ) Focal thickening of the cortex. ( 2 ) Blurring of the gray matter-white matter junction. ( 3 ) Tapering of white matter signal intensity alteration toward the ventricle on FLAIR and on T2WI. (4)Focal brain hypoplasia. (5)Increased signal intensity of gray matter on FLAIR. (6)Increased signal intensity of gray matter on T2 WI. ( 7 ) Increased signal intensity of subcortical white matter on FLAIR.(8) Increased signal intensity of subeortical white matter on T2WI. (9) Decreased signal intensity of subcortical white matter on T1 WI. The χ2 tests and corrected χ2 tests were used for comparison between the two groups. Results In the 44 cases, there were 30 cases with FCD type Ⅰ and 14 cases with FCD type Ⅱ. FCD was identified by MRI in 32 cases. Blurring of the gray-white matter junction is the most common sign of FCD (23 cases). There were 21 cases identified by MRI in FCD type Ⅰ group. Focal brain hypoplasia is a typical sign of FCD type Ⅰ , which was found in 11 cases in FCD type Ⅰ group but none in FCD type Ⅱ group. There was statistically significant difference between the two groups (continuity corrected χ2 =5. 0286,P =0. 0249) . In FCD type Ⅱ group, 11 cases were identified by MRI. Increased cortical thickness was found in 10 eases in FCD type Ⅱ group and 11 cases in FCD type Ⅰ group ( χ2 =4. 6234 ,P =0. 0315). Increased signal intensity of subcortical white matter on FLAIR was found in 9 cases in FCD type Ⅱ group and 7 cases in FCD type Ⅰ group (χ2 =6.9180,P =0.0085). Tapering of white matter signal intensity alteration toward the ventricle was found in 4 cases in FCD type Ⅱ group and none in FCD type Ⅰ group ( continuity corrected χ2 = 6. 2883, P = 0. 0122). The above-mentioned three MRI findings showed statistically significant difference between the two groups and were features of FCD type Ⅱ.All of the other MRI findings showed no statistically significant difference between the two groups. Conclusions Different pathological subtypes of FCD have different MRI characteristics. It is helpful to make preoperative diagnosis and planning.
