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.

Objective:To observe the effect of different clinical factors on the level of parathyroid hormone (PTH) and to predict the possibility of permanent hypothyroidism (PHP) after total thyroidectomy (TT) by monitoring the levels of PTH in serum and drainage fluid after TT.Methods:Retrospective analysis was made on 150 patients who underwent TT for papillary thyroid carcinoma (PTC) in the Department of Thyroid Head and Neck Surgery in Jilin Cancer Hospital from Jan. 2020 to Aug. 2021. The changes of serum PTH were recorded at 1, 3, 7, 30 days and 6 months after surgery. The risk factors of postoperative hypoparathyroidism (HP) were investigated by single factor and multi factor methods. The impairment of parathyroid function was predicted combined with the level of PTH in the drainage fluid 1 day after operation.Results:After TT, serum PTH returned to normal value in most patients 1 month after operation. The proportion of PHP was 3.33% (5/150). Univariate analysis showed that bilateral central lymph node dissection, Hashimoto’s thyroiditis, tumor diameter ≥2 cm and intraoperative selective parathyroid autologous transplantation were risk factors for temporary hypoparathyroidism (THP). Multivariate analysis showed that BCND ( OR=0.322, P=0.001) , intraoperative selective parathyroid autograft ( OR=5.442, P=0.001) and tumor diameter ≥2 cm ( OR=2.247, P=0.003) were independent risk factors for THP. ROC curve was used to compare the predictive effect of postoperative serum and drainage PTH levels on postoperative PHP. The statistical results showed that the highest predictive effect of postoperative PHP was found on the first day of drainage PTH level within 1 week after operation (AUC 0.81) . 54 cases whose serum PTH was lower than normal value on the first day after operation were divided into 4 groups according to the level of PTH in drainage fluid from high to low. The results showed that the lower the level of PTH in drainage fluid, the greater the possibility of PHP ( P<0.05). Conclusions:Most of the patients with low PTH one month after operation develop PHP, while bilateral central lymph node dissection, intraoperative selective parathyroid transplantation, tumor diameter ≥2 cm are risk factors for THP after TT. If the serum PTH is lower than the normal value on the first day after operation, there is a possibility of PTH. The lower the PTH in the drainage fluid, the greater the possibility of PHP, which should be paid attention to in clinical practice.

【Objective】 To clarify the hematological characteristics and current situation of chronic mountain sickness among Tibetan residents in extreme high altitude area (more than 5 000 m above the sea level) of Ali district based on the analysis of physical examination and blood test results. 【Methods】 Totally 250 Tibetan residents were selected by convenient sampling for blood oxygen saturation (SpO2), heart rate, and blood routine examination. Chronic mountain sickness was determined according to the hemoglobin (Hb) level and SpO2. 【Results】 The red blood cell (RBC), Hb and hematocrit (HCT) of the Tibetan residents at 5 200-meter altitude were all higher than the normal physiological reference range of China. Mean red blood cell volume (MCV), mean red blood cell hemoglobin content (MCH), mean red blood cell hemoglobin concentration (MCHC), white blood cell (WBC) and platelet (PLT) were in the upper limit of the reference value. The RBC, Hb, HCT and MCHC of male Tibetan residents were higher than those of females, while PLT was lower than that of females, with significant differences. There were no statistical differences in MCV, MCH or WBC among different genders of Tibetan residents. The SpO2 of the Tibetan residents was about 85% of the normal value, and the males had higher SpO2 than the females in the same age group, and the difference was statistically significant, but the heart rate did not differ significantly. The prevalence rate of chronic mountain sickness in this area was as high as 16.4%, and the prevalence rate of heavy manual workers was significantly higher than that of light manual workers, with significant differences. 【Conclusion】 The high-altitude anoxic environment causes the changes in red blood cells, hemoglobin, and oxygen saturation of local residents, and the prevalence of chronic mountain sickness increases significantly. Labor intensity is one of the risk factors for chronic mountain sickness in high-altitude areas.

Objective To evaluate the effect of the rehabilitation software based on information-motivation-behavioral skills(IMB)model on meeting the rehabilitation needs, increasing the continuation of rehabilitation and the rehabilitation compliance, improving the outcome of rehabilitation among elderly patients with fracture. Methods Based on the theory of"information-motivation-behavior"and the unity of human- computer interaction as the design concept, the status quo of rehabilitation training and rehabilitation needs of elderly patients with fracture were reviewed. The rehabilitation training test was applied to 30 patients with fracture in orthopedic department of our hospital. 30 patients in the same period were randomly selected as control group. All patients underwent Self-Rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores before and 1 and 3 months after operation. Differences were tested using Student's t test. Results Developed rehabilitation application software based on information module、motivation module and behavior module. The test group using this software for rehabilitation training was compared with the control group. The results showed that there was no significant difference in preoperative SAS and SDS scores between the two groups (t=-0.648,-0.284, P>0.05). At 1 and 3 months after operation, the SAS scores in the test group were (40.05 ± 6.77), (32.01 ±5.86), which were lower than (45.50 ± 11.32), (39.55 ± 5.67) in the control group (t=-4.14,-4.89, P<0.01). The SDS scores in the test group were (42.30 ± 9.86), (33.23 ± 6.56), which were lower than (46.50 ± 10.32), (38.45 ± 7.80) in the control group (t=-3.52,-3.82, P=0.001). Conclusion Rehabilitation software can influence the rehabilitation behavior of elderly fracture patients from information and motivation factors, provide professional guidance and rehabilitation intervention, and promote the implementation of active rehabilitation.
