Objective To investigate the effects of electroacupuncture at Sanyinjiao (SP6) and Yinlingquan (SP9) on muscle repair in the gastrocnemius muscle damaged rats and its possible mechanism. Methods 30 male Sprague-Dawley rats were randomly divided into blank group (n=10), model group (n=10) and electroacupuncture group (n=10). The latter 2 groups were modeled with gastrocnemius muscle crush injury. The electroacupuncture group received electroacupuncture at Sanyinjiao and Yinlingquan for 14 days. Their gastrocnemius was observed with HE staining, and the expressions of basic fibroblast growth factor (bFGF) and insulin-like growth factor-1 (IGF-1) in gastroc-nemius tissues and the serum were determined with immunochemical assay and enzyme-linked immunosorbent assay (ELISA). Results Compared with the model group, there was less damage in the electroacupuncture group, with more expression of bFGF and IGF-1 in tis-sues (P<0.01) and serum (P<0.05). Conclusion Electroacupuncture can promote muscle repair after gastrocnemius muscle damage in rats, which may be related to the increase of the bFGF and IGF-1 expression in gastrocnemius tissue and serum.

Allergic rhinitis (AR) is one kind of nose mucous membrane inflammation reactiveness disease, which is mediated by IgE for the environment sensitizin. The major clinical symptoms are: nose itch, the sneeze, nasal discharge, nasal obstruction and so on. It is thought that the acient disease named "Bi Qiu" has included AR. By comparing the AR clinical manifestation characteristic with trditional Chinese medicine (TCM) "Feng/wind" induced disease characteristic and the "Feng/wind" disease clinical manifestation characteristic, we can know that AR should belong to the "Feng/wind" disease category of TCM. It is shown that the "Feng/ wind" medicine is the most windly appeared in AR treatment formulas of TCM clinical research data (in each formular) in the past 10 years. To aim directly at three knids of problem in TCM clinical research, we discussed five problems which should pay close attention to the feature research, therefor to provide a mirror for AR clinical and experimental studies by TCM.

X-ray scattering technique, infrared spectroscopy and scanning electron microscopy proved the inclusion compound had been formed. Conclusion Optimum extraction and inclusion processes are stable and feasible, and can provide research foundation for further research and development of preparation.

Objective To evaluate the clinical effect of hybrid operation in treating Stanford type B aortic dissection. Methods During the period from January 2011 to December 2013, hybrid operation was performed in 33 patients with complex Stanford type B aortic arch dissection. The patients included 28 males and 5 females with a average age of (50±12) years. The clinical effect and the complications, occurring in perioperative period and in 24-month follow-up period, were analyzed. Results The operation was successfully accomplished in all 33 patients, with a technical success rate of 100%. The average hospitali-zation time was 20 days. After the operation, 29 cases were followed up for 3-34 months and 4 cases were lost to follow up, the following-up rate was 87.9%. In 21 cases, the following-up time was over 12 months. Postoperative angiography showed that there was no typeⅠendoleak; complications included pulmonary infection (n=1), strokes (n=1), reversible abnormal renal function (n=6) and retrograde aortic arch dissection (n=1). No paraplegia occurred. During hospitalization time, two cases died, the mortality was 6.06%. During the following-up time, graft infection occurred in one case and continued presence of retrograde aortic arch dissection was observed in one case. Conclusion The complication occurrence after hybrid operation for Stanford type B aortic dissections is low. The hybrid technique is very safe and feasible, but several serious postoperative complications should not be ignored. The long-term effectiveness needs to be further clarified by systemic and large sample studies.

Objective To investigate the iodine intake level and the prevalence of thyroid nodules in Harbin City,and to study the correlation between the concentration of urinary iodine and the prevalence of thyroid nodules.Methods In Harbin,18 communities were randomly selected and specimens were collected from fasting morning urine from 2015 to 2017.The urine iodine concentration (UIC) was detected by arsenic cerium catalytic spectrophotometry,and the thyroid nodule was examined by B ultrasound.Results A total of 2 552 residents aged (45.79 ± 12.06) years old agreed to participate in the study,including 371 males and 2 181 females.The median UIC in all participants was 159.8 μg/L,there was a significant difference in urine iodine frequency distribution among age groups (x2 =40.097,P ＜ 0.01).Furthermore,the median UIC in male was 166.6 μg/L,and in female was 156.2 μg/L.There was a significant difference in UICs between male and female (U =2.122,P ＜ 0.05).The prevalence of total thyroid nodules in all participants was 48.75％ (1 244/2 552),and the standardized rate was 40.55％.Significant difference in the detection rate of thyroid nodules was observed among age groups (x2 =114.922,P ＜ 0.01),and there was a positive and significant correlation between the detection rate of thyroid nodules and increasing age (xtrand =111.746,P ＜ 0.01).Furthermore,in male,41.24％ (153/371) had thyroid nodules,with standardized prevalence rate of 41.13％,and in female,50.02％ (1 091/2 181) had thyroid nodules,with standardized prevalence rate of 49.20％.Likewise,there was a significant difference in the detection rate of thyroid nodules between male and female(x2 =9.790,P ＜ 0.01).The detection rate of thyroid nodules in the iodine deficient population (urinary iodine was 0-＜ 100 μg/L) was 55.58％ (244/439),and the incidence of thyroid nodules in the iodine adequate or optimal population (urinary iodine was 100-＜ 200 μg/L) was 46.68％ (591/1 266).Conclusions The total iodine level of the population in Harbin City of Heilongjiang Province is at adequate level.The detection rate of thyroid nodules is high and it is increased with age.The detection rate of thyroid nodules is higher in female than male.Regular detection of urine iodine and adjusting iodine nutrition will help prevent thyroid nodules.

OBJECTIVE:To study curative effect of the combination of cyclosporine A,mycophenolate mofetil,anti-thymocyte globulin,interleukin-11 and short-term methotrexate as acute graft-versus-host disease(aGVHD) prophylaxis on HLA-matched unrelated donor or HLA-mismatched related donor allogenic peripheral blood stem cell transplantation(Allo-PBSCT).METHODS:Thirteen patients with haematological malignancies who underwent HLA-matched unrelated donor or HLA-mismatched related donor Allo-PBSCT with the combination of cyclosporine A as aGVHD prophylaxis at Haikou Municipal People's Hospital from September to November 2008 were selected,including 7 of unrelated donor,3 of haplotype transplantation,and 3 of 1-locus mismatched.The conditioning regimen was performed at 7 days prior to transplantation,with cyclosporine A 5-10 mg/(kg?d),12 hours per time with twice per day.From day 7 prior to transplantation,mycophenolic acid was intravenous drip once per day,then 2.5 mg/(kg?d) antithymocyte globulin at days 5-2 prior to transplantation,1.5 mg/d interleukin 11 was subcutaneous injected at day 2 prior to and 10 days after transplantation,followed by intravenous drip 15 mg/m2 amethopterin at day 1 and 10 mg/m2 at days 3,6,11 after transplantation.The drug doge was reduced and stopped gradually after 3-6 months,which could be prolonged for haplotype grafter.Recombinant human granulocyte colony-stimulating factor was injected subcutaneously at day 3 prior to transplantation,and PBSCT was collected at days 4 and 5 after medication,which was infused to patients with subclavian vein at the same day.In total(7.82-9.11)?108/kg mononuclearcell and(2.9-7.7)?106/kg CD34+ cells were infused.RESULTS:Hematopoiesis was rebuilt in all patients with 46.15%(6/13) aGVHD incidence rate,including 8 %(1/13) of Ⅲ-Ⅳ aGVHD.Up to April of 2009,all patients live and work as normal except one patient who can not visit public places.CONCLUSION:The combination of cyclosporine A,mycophenolate mofetil,anti-thymocyte globulin,interleukin-11 and short-term methotrexate is effective in the prevention of aGVHD.

This study aimed to explore key quality control factors that affected the prognosis of intensive care unit (ICU) patients in Chinese mainland over six years (2015-2020). The data for this study were from 31 provincial and municipal hospitals (3425 hospital ICUs) and included 2 110 685 ICU patients, for a total of 27 607 376 ICU hospitalization days. We found that 15 initially established quality control indicators were good predictors of patient prognosis, including percentage of ICU patients out of all inpatients (%), percentage of ICU bed occupancy of total inpatient bed occupancy (%), percentage of all ICU inpatients with an APACHE II score ⩾15 (%), three-hour (surviving sepsis campaign) SSC bundle compliance (%), six-hour SSC bundle compliance (%), rate of microbe detection before antibiotics (%), percentage of drug deep venous thrombosis (DVT) prophylaxis (%), percentage of unplanned endotracheal extubations (%), percentage of patients reintubated within 48 hours (%), unplanned transfers to the ICU (%), 48-h ICU readmission rate (%), ventilator associated pneumonia (VAP) (per 1000 ventilator days), catheter related blood stream infection (CRBSI) (per 1000 catheter days), catheter-associated urinary tract infections (CAUTI) (per 1000 catheter days), in-hospital mortality (%). When exploratory factor analysis was applied, the 15 indicators were divided into 6 core elements that varied in weight regarding quality evaluation: nosocomial infection management (21.35%), compliance with the Surviving Sepsis Campaign guidelines (17.97%), ICU resources (17.46%), airway management (15.53%), prevention of deep-vein thrombosis (14.07%), and severity of patient condition (13.61%). Based on the different weights of the core elements associated with the 15 indicators, we developed an integrated quality scoring system defined as F score=21.35%xnosocomial infection management + 17.97%xcompliance with SSC guidelines + 17.46%×ICU resources + 15.53%×airway management + 14.07%×DVT prevention + 13.61%×severity of patient condition. This evidence-based quality scoring system will help in assessing the key elements of quality management and establish a foundation for further optimization of the quality control indicator system.
