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）.

Objective:To explore and compare early postoperative clinical outcomes between dynamic and classical superior capsular reconstruction for the treatment of irreparable post-superior massive rotator cuff tears (MIRCTs).Methods:29 patients with MIRCTs treated with autologous fascia dynamic SCR (14) and classical SCR (15) at Department of Sports Medicine of the First Affiliated Hospital of Army Medical University from September 2019 to March 2022 were retrospectively analyzed on preoperative and final follow-up pain visual analogue scale (VAS), Constant-Murley score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) score, range of motion (ROM), acromiohumeral distance (AHD), Sugaya classification and Goutallier classification.Results:All 29 patients were followed up with an average follow-up time of 36.50±8.18 months for dynamized SCR and 29.33±9.15 months for classical SCR, respectively. There was no significant difference between the two groups in terms of gender, age, course of disease and preoperative AHD ( P>0.05). At the final follow-up, there was no significant difference in the degree of improvement in forward flexion (81.79°±36.14° vs. 69.00°±40.19°, t=0.899, P=0.377), abduction [87.50°(71.25°, 122.50°) vs. 80.00°(45.00°, 95.00°), Z=-1.400, P=0.172] and internal rotation [5.00°(5.00°, 6.00°) vs. 4.00°(1.00°, 6.00°), Z=-0.871, P=0.400]; external rotation improved significantly in the dynamic SCR group compared to classical SCR group [37.50°(30.00°, 41.25°) vs. 25.00°(15.00°, 30.00°), Z=-2.285, P=0.019]. Although both groups showed clinical improvements, no significant difference was found between the dynamic SCR group and the classical SCR group on VAS [4.00(3.75, 5.00) vs. 4.00(3.00, 5.00), Z=-0.029, P=0.949], ASES score (50.99±7.98 vs. 46.47±13.73, t=1.074, P=0.293), Constant-Murley score [62.50(54.00, 69.50) vs. 56.00(47.00, 62.00), Z=-1.956, P=0.112] and UCLA score (20.21±3.53 vs. 18.40±3.87, t=1.315, P=0.199). At the final follow-up, patients in the dynamic SCR group had a higher degree of improvement in AHD (3.66±2.22 mm vs. 2.00±1.75 mm, t=2.247, P=0.033). There was no significant difference in Sugaya grading between the two groups at the final follow-up ( Z=-0.370, P=0.747). As for the degree of improvement in Goutallier's grading, there was an improvement in the dynamic SCR group at the final follow-up versus the preoperative period ( Z=-2.101, P=0.036), while there was no significant difference in the degree of improvement in the classical SCR group at the final follow-up versus the preoperative period ( Z=-0.700, P>0.05). Conclusion:Both dynamic SCR and classical SCR for MIRCTs significantly improved shoulder function. Significant improvements in external rotation, AHD and Goutallier grading were observed in the dynamic SCR group compared to the classical SCR group.

【Objective】 To estimate the prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province so as to provide evidence for the prevention and control of non-communicable diseases. 【Methods】 We used the data of adults aged 18 years and older collected in the baseline survey of Shaanxi Project in the Regional Ethnic Cohort Study in Northwest China. Multinomial logistic regression was used to explore the associated factors for multimorbidity. Exploratory factor analysis was used to extract patterns of multimorbidity. 【Results】 The prevalence of multimorbidity was 10.7% among the 44 442 participants. Age increase, being males, urban residence, and being overweight or obesity were positively associated with multimorbidity. Compared with women, men had a higher risk of multimorbidity. The OR and 95% CI was 1.25 (1.12-1.39). The risk of multimorbidity increased with age among adults. Compared with participants aged 18.0-34.9 years, the ORs and 95% CIs of those aged 35.0-44.9, 45.0-54.9, 55.0-64.9, and ≥65.0 years were 4.73 (3.47-6.46), 15.61 (11.60-21.00), 41.39 (30.76-55.70) and 90.04 (66.58-121.77), respectively. The primary multimorbidity patterns among adults in Shaanxi were cardiovascular-metabolic multimorbidity (5.4%), viscero-articular multimorbidity (1.0%), and respiratory multimorbidity (0.3%). 【Conclusion】 More than one in ten adults in Shaanxi Province had multimorbidity, and the predominant pattern of multimorbidity was cardiovascular-metabolic multimorbidity. The prevention and control of non-communicable diseases should be reinforced in middle-aged and older people, males, people living in the urban, and overweight or obese people. More attention should be paid to the prevention and control of cardiovascular-metabolic diseases.

【Objective】 To evaluate the dietary quality with the dietary balance index (DBI_16) and the association between dietary quality and bone mass among middle-aged and elderly people in Gansu Province so as to provide evidence for improving dietary quality and bone health status of Gansu population. 【Methods】 Based on the information of the type and quantity of food intake and the bone mass of middle-aged and elderly people aged 35 years and above collected by the Gansu Project in the Regional Ethnic Cohort Study in Northwest China, DBI_16 was used to evaluate the intake level of cereals, vegetables, fruits, milk, beans, fish and shrimp, eggs and other foods, and the degree of inadequate, excessive and unbalanced dietary intake of the participants. Multiple linear regression was used to evaluate the associations of three component indexes of DBI_16, high bound score (DBI_HBS), low bound score (DBI_LBS), diet quality distance (DBI_DQD), and seven single indexes of DBI_16 with bone mass. 【Results】 Analyses of the dietary and bone mass data of 11,840 participants showed that 44.8% of participants consumed excessive amounts of cereals compared to the dietary recommendation. 96.3%, 90.6%, 90.1%, 71.9%, 95.1% and 60.3% of participants’ intake of vegetables, fruits, milk, soybeans, fish and shrimp, and eggs, respectively, were inadequate. 47.7% participants consumed less than 10 types of food. 2.3% participants’ DBI_LBS levels were appropriate. 54.7% participants’ DBI_HBS levels were appropriate. Only 1.2% participants’ DBI_DQD reached a balanced level. The bone mass level in the study population was (2.5±0.6) kg [(2.8±0.5) kg for men and (2.3±0.5) kg for women]. After adjusting for sociodemographic characteristics, lifestyle, total dietary energy intake and body mass index, DBI_LBS and DBI_DQD were negatively associated with bone mass [β and 95% CI was -0.002 01 (-0.003 62--0.000 40) and -0.001 76 (-0.003 09--0.000 43), respectively]. 【Conclusion】 Dietary intake imbalance is common among middle-aged and elderly people in Gansu Province, and the more severe the dietary intake imbalance, the lower the bone mass level.

【Objective】 To compare the ability of body mass index （BMI）， body fat percentage （BFP）， waist circumference （WC）， waist-to-height ratio （WHtR）， visceral fat index （VFI） and the combinations of two kinds of obesity indices to predict the risk of hypertension. 【Methods】 Data collected in the baseline survey of “Gansu Province’s Urban and Rural Natural Population Cohort Establishment and Tumor Follow-up Study” were analyzed. Area under the curve （AUC） of ROC curve with covariates was used to analyze and compare the effects of individual obesity evaluation index and the combination of two kinds of obesity indices in predicting the risk of hypertension. 【Results】 Analyses of data of 20，079 adults showed that the AUC of BMI， WC， WHtR， BFP and VFI was 0.636， 0.604， 0.615， 0.614 and 0.619， respectively. AUC of the combination of BMI and WC （0.643） was higher than that of BMI （0.636）； however， the change rate of AUC was only 1.09%. AUC of the combinations of WC， WHtR and VFI， the three central obesity evaluation indices， and BFP， a general obesity evaluation index， were lower than that of BMI. The optimal cutoff value for BMI was 24.2 kg/m². 【Conclusion】 The effect of BMI in predicting the risk of hypertension is better than that of BFP， WC， WHtR and VFI. The effects of the combinations of the two kinds of obesity evaluation indices are not better than that of BMI. To prevent and control hypertension， adults should keep their BMI under overweight.

Objective:To investigate whether FcγRⅡb rs775 single nucleotide polymorphism confers susceptibility to Hashimoto′s thyroiditis and its impact on expression of FcγRⅡb protein on B cell surface.Methods:A total of 187 Hashimoto′s thyroiditis patients(HT group) were enrolled, including 46 males(24.60%) and 141 females(75.40%), with a median age of 43(32, 53) years, and 187 healthy controls(conrol group), including 62 males(33.16%) and 125 females(66.84%), with a median age of 41(31, 51) years. The peripheral blood of two groups were sequenced, genotype and allele frequencies distribution of FcγRⅡb rs775 T>C were compared with clinical parameters as strata between the two groups. At the same time, the expression of inhibitory receptor FcγRⅡb on B cell surface was detected using flow cytometry.Results:Compared with control group, the mutant homozygous CC genotype was obviously enrichment in HT group( OR=3.321, 95% CI 1.175-9.386, P=0.018), and the proportion of CC genotype increased in male of HT group( P=0.076). However, there is no significant difference in genotype and allele frequencies between control group and HT group after stratification by sex. In addition, the percentage of FcγRⅡb on B cell surface decreased significantly in HT group( P=0.029). Conclusion:There was no significant correlation between FcγRⅡb polymorphism and the down-regulation of FcγRⅡb protein on B cell surface in Hashimoto′s thyroiditis patients, and FcγRⅡb can be a predisposed factor for Hashimoto′s thyroiditis.

Objective To study the relationship between the ratio of target volume to lung volume and the prescription dose in intensity modulated radiation therapy (IMRT) for esophageal cancer, so as to help clinicians to choose the appropriate prescription dose according to the target situation. Methods 80 patients with esophageal cancer were randomly selected. The lesion range included all types of esophageal cancer, and the target area was outlined according to ICRU (International Commission Radiological Units) 50 and ICRU62. Set statistical parameters and plan objectives. Statistical analysis was performed according to the statistical results of the parameters. The critical value of volume ratio is obtained by fitting calculation. Results there was a positive linear correlation between volume ratio and lung V₅, V₂₀, V₃₀ and average lung dose. The critical value of volume ratio is 10% for 60 Gy and 13% for 50 Gy. Conclusion according to the research results, it can be predicted that when the ratio of target volume to lung volume is more than 10%, the prescribed dose should not be higher than 60 Gy; when the ratio of target volume to lung volume is more than 13%, the prescribed dose should be selected cautiously, meanwhile in the condition of whose target volume exceeds lung segment the prescribed dose. This provides a reference for clinicians when choose the prescription dose and target range while making the target delineation.

In vitro anticoagulation is a key technique in continuous renal replacement therapy (CRRT), and heparin was once the preferred anticoagulant for CRRT, but its clinical application is limited due to the high risk of bleeding. Citrate, as a new regional anticoagulant, has received more and more attention and recommendation in recent years, but there are still controversies over its application in patients with liver failure. With reference to relevant literature in China and globally, this article reviews the metabolic characteristics and monitoring methods of regional citrate anticoagulation and its safety in CRRT for patients with liver failure.

Objective: To investigate the efficacy of alternative donor (AD) in the treatment of aplastic anemia (AA) in children. Methods: The clinical data of AA children who received AD HSCT in our center from Apr. 2010 to Dec. 2016 were retrospectively analyzed. The overall survival (OS) rate, implant success rate, incidence of acute and chronic graft-versus-host disease (GVHD) were statistically analyzed. Results: A total of 109 children with acquired AA, including 64 severe AA (SAA) , 32 very severe AA (VSAA) and 13 transfusion dependent non-severe AA (NSAA) , were recruited in this retrospective AD HSCT study, the median age was 6 (0.8-18) years old. Of them, 44 patients with 10/10 matched unrelated donor (MUD) , 44 patients with mismatched unrelated donor (MMUD) and 21 patients with mismatched related donor (MMRD) . All patients did not receive ATG before HSCT and the active infection was excluded. Except 3 patients suffered from a second graft failure (2 of them rescued by second HSCT) , 106/109 (97.2%) were engrafted with neutrophil and platelet recovery occurring at a median of 13 days (range, 9-19) and 16 days (range, 10-81) post-transplant. Until day 100 post transplantation, the incidence was 74.3% (81/109) for acute GVHD (aGVHD) and 39.4% (43/109) for grade Ⅱ-Ⅳ aGVHD, 30.7% (31/101) and 9.9% (10/101) for overall chronic GVHD (cGVHD) and moderate cGVHD, respectively, and nobody developed an extend cGVHD. After median follow up of 39 (0.7-103) months for all patients, 13 of 109 patients died. The estimated 5-year overall survival (OS) of the entire cohort was 88.1% (95%CI 81.1%-91.4%) with no difference among the MUD, MMUD and MMRD cohort (93.2%, 84.1% and 85.7%, respectively, P=0.361) . Conclusion These excellent outcomes suggest that unmanipulated AD PBSC is a good HSCT source for children with SAA. It’s reasonable to consider AD HSCT as first line therapy for SAA children without matched sibling donor. Better strategies are required to prevent GVHD.

Objective:To explore the feasibility of quantitative evaluation of extracellular volume (ECV) fraction in acute ST-segment elevation myocardial infarction (STEMI) by dual-layer spectral detector CT.Methods:The clinical and imaging data of 20 patients with STEMI who underwent cardiac contrast-enhanced CT and MRI from January to October 2019 in Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine were retrospectively analyzed.The dual spectral detector was used in the enhanced CT scan of the coronary artery with retrospectively gate and the late iodine enhancement with prospective gate. Conventional image and holographic spectral image were obtained by iterative and spectral reconstruction. The short axis image of the heart matched with MR image was obtained by multiplanar reconstruction. Based on the data of spectral based image, the IDD map was reconstructed for the calculation of myocardial CT-ECV during the late iodine enhancement. ECV of infarcted myocardium, salvageable myocardium and remote myocardium based on CT and MRI were calculated respectively. Bland-Altman consistency test and intra group correlation coefficient analysis (ICC) were used to compare the consistency of two measurements and different methods. The correlation between CT-ECV and MRI-ECV was compared by Spearman method.Results:The CT-ECV values of infarcted, salvageable, and remote myocardium were 51.21 (49.27, 53)%, 38.64 (36.17, 40)%, and 51.21 (49.27, 53)%, respectively. The difference was statistically significant ( H= 43.17, P<0.01). The CT-ECV value of infarcted myocardium was significantly higher than that of salvageable myocardium and remote myocardium ( Z=-24.60, 35.40, P<0.01), but there was no significant difference between salvageable myocardium and remote myocardium ( Z= 10.80, P=0.15). The T 1 values of infarcted myocardium, salvageable myocardium and remote myocardium were (1 554.85±70.94), (1 443.85±67.28) and (1 307.05±91.73) ms respectively, the difference was statistically significant ( F=51.35, P<0.01). The T 1 value of infarcted myocardium was higher than that of salvageable myocardium and remote myocardium ( t=-5.07, 9.55, P<0.01), and salvageable myocardium was significantly higher than that of remote myocardium ( t=5.38, P<0.01). The MRI-ECV values of infarcted myocardium, salvageable myocardium and remote myocardium were 55.00 (49.27, 57.75)%, 33.50 (29.00, 35.00)%,and 27.00 (26.00, 29.00)%, respectively. The difference was statistically significant ( Z= 47.12, P<0.01). MRI-ECV of infarcted myocardium was significantly higher than that of salvageable myocardium and remote myocardium ( Z=37.45, -20.30, P< 0.01), and salvageable myocardium was significantly higher than that of remote myocardium ( Z = 17.15, P<0.05). The difference between CT-ECV and MRI-ECV measured by two physicians was good. The bias of Bland-Altman analysis was -0.1% (95% CI:-5.5%-5.2%), 0.8% (95% CI:-9.8%-8.2%), and the ICC values were 0.92 and 0.94, respectively. The bias of Bland-Altman analysis in CT-ECV and MRI-ECV consistency test was 4.00% (95% CI:-9.0%-16.9%) and ICC value was 0.88, which had a good correlation ( r=0.75, P=0.001). Conclusions:The iodine density based ECV fromdual-layer spectral detector CT can be used to quantitatively evaluate the changes of extracellular space after acute STEMI, which is helpful to quantitatively evaluate the histological changes after myocardial ischemia.
