Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.

Objective:To retrospectively analyze the clinical outcomes of single unrelated cord blood transplantation (UCBT) in children with high risk and refractory acute myeloid leukemia (AML) .Methods:Between June 2008 and December 2018, a total of 160 consecutive pediatric patients with AML received single UCBT (excluding acute promyelocytic leukemia) . Myeloablative conditioning (MAC) regimen were applied. All patients received a combination of cyclosporine A (CsA) and mycophenolate mofetil (MMF) for the prophylaxis of graft -versus- host disease (GVHD) .Results:The cumulative incidence of neutrophil cells engraftment at day +42 and platelet recovery at day +120 was 95.0% (95% CI 90.0%-97.5%) at a median of 16 days after transplantation (range, 11-38 days) and 85.5% (95% CI 83.3%-93.4%) with a median time to recovery of 35 days (range, 13-158) , respectively. Incidence of grades Ⅱ-Ⅳ and Ⅲ-Ⅳ acute GVHD and chronic GVHD were 37.3% (95%CI 29.3%-45.2%) , 27.3% (95% CI 20.0%-35.0%) and 22.4% (95% CI 15.5%-28.7%) , respectively. The transplant-related mortality (TRM) at 360 day was 13.1% (95% CI 8.4%-18.9%) . The 5-year cumulative incidence of relapse was 13.8% (95% CI 8.5%-20.3%) . The 5-year disease-free survival (DFS) and overall survival (OS) were 71.7% (95% CI 62.7%-77.8%) and 72.2% (95% CI 64.1%-78.7%) , respectively. The 5-year GVHD and relapse free survival (GRFS) was 56.1% (95% CI 46.1%-64.9%) . The 5-year cumulative recurrence rates of CR1, CR2, and NR groups were 5.3%, 19.9%, and 30.9% ( P=0.001) , and the 5-year OS rates were 79.9% (95% CI 70.3%-86.7%) , 71.1% (95% CI 50.4%-84.4%) and 52.9% (95% CI 33.0%-69.3%) ( χ2=7.552, P=0.020) , respectively. Conclusions:For pediatric patients with high risk and refractory AML, UCBT is a safe and effective treatment option, and it is favorable to improve the survival rate in CR1 stage.

Objective:To improve accuracy of prediction amount of length of gastric tube placed through nose and reduce occurrence of adverse events thorough clinical observation of measurement of length of nasogastric tube placement in critically ill children.Methods:Using the convenient sampling method, critically ill children who were hospitalized and needed a nasogastric tube in Pediatric Intensive Care Unit (PICU) of Beijing Children's Hospital Affiliated to Capital Medical University were selected from April to September 2019. The prediction method of "nos-ear-xiphoid (NEX) increased by 5 cm" (NEX+5 cm) was adopted. The values of placed length in this study were collected and compared with those predicted by traditional measurement method (namely NEX) , improved "nose-ear-mid-umbilicus" (NEMU) and formula method.Results:A total of 52 critically ill children were enrolled in this study. The length of placed nasogastric tube was 31.5 (28.3, 35.8) cm, and 43 cases (82.7%) were determined to be qualified by X-ray. The length of gastric tube required to be placed in children was 27.0 (24.1, 31.0) cm according to the NEX method, and the length of gastric tube required to be placed in children was 26.1 (22.5, 29.0) cm measured by the formula method. Both were shorter than that measured by NEX+5 cm, and the differences were statistically significant ( P<0.01) . The NEMU method measured the length of gastric tube to be inserted into the child to be 31.0 (28.3, 36.0) cm. Compared with the length measured by NEX+5 cm, and the difference was not statistically significant ( P>0.05) . Conclusions:This study uses NEX+5 cm to predict the actual length of the gastric tube inserted through the nose. The accuracy is relatively high and the operation method is simple. It is necessary to consider individual differences in clinical applications, especially the large variability in infants and young children. After catheterization, abdominal ultrasound, X-ray and other auxiliary examination methods should be used to determine the location of catheterization, and individualized catheterization programs should be given to children according to different therapeutic objective.

Objective:To investigate the value of pericoronary adipose tissue histogram parameters based on coronary CT angiography (CTA) images for the differentiation of acute coronary syndrome and stable coronary artery disease.Methods:The clinical data and CTA images of 93 patients with coronary CTA examination in Suzhou Kowloon Hospital from 2013 to 2018 were analyzed retrospectively. There were 39 patients with acute coronary syndrome (acute coronary syndrome group) and 54 patients with stable coronary artery disease (stable coronary artery disease group). A region of interest (ROI) was drawn around the stenosis of the coronary arteries, with CT attenuation ranging from-190 to -30 HU to exclude non-adipose tissue. The CT attenuation of ROI excluding non-adipose were measured and histogram analysis was performed. The obtained parameters included the mean value, median value and the 5th, 10th, 45th, 55th, 70th and 95th percentiles. The differences in histogram parameters between the two groups were compared, and then the value of each parameter in differentiating acute coronary syndrome and stable coronary artery disease was evaluated based on receiver operating characteristic (ROC) analysis. The stepwise regression of multivariate logistic regression analysis was used to identify the useful features and establish the final prediction model. The ROC curve of the final model was calculated and its value was analyzed.Results:The mean, median and the 5th, 10th, 45th, 55th,70th and 95th percentile differences between the acute coronary syndrome group and the stable coronary artery disease group were statistically significant (all P<0.05). The ROC curve for the median and the 95th percentile had the same area under curve (AUC) of 0.73. The sensitivity, specificity and AUC of the diagnostic model established by multiple logistic regression were 82.1%, 89.1% and 0.90 respectively. Conclusion:CT attenuation histogram of pericoronary adipose tissue is of high value in differentiating acute coronary syndrome from stable coronary artery disease.

Objective To systematically evaluate the clinical effect and safety of repaglinide and metformin for treating diabetes mellitus (MD) of secondary failure of sulfonylurea (SFS).Methods The randomized controlled trials (RCT) at home and abroad on the comparison of effect and safety of repaglinide and metformin in treating MD with SFS were retrieved.The modified Jadad scale was employed to evaluate the literature quality.The RevMan5.3.1 software was used for conducting the meta analysis.Results A total of 10 RCT were included.The meta-analysis results showed that compared with metformin for treating MA with SFS,repaglinide decreased the fasting blood glucose effectively (MD=-2.30,95 ％ CI:-2.53--2.06,P＜0.01),increased the fasting C-peptide (MD=0.06,95％CI:0.02-0.11,P=0.01),reduced the postprandial 2 h blood glucose (MD=-2.17,95 ％CI:-2.44-1.89,P＜0.01) and decreased glycosylated hemoglobin (MD=-2.60,95％CI:-3.21--2.00,P＜0.01) as well as the adverse reactions (RR=0.05,95％CI:0.02-0.09,P＜0.01).However,there was no statistical difference in fasting insulin between the repaglinide and metformin groups (MD=0.18,95％CI:-0.18-0.54,P=0.32).Conclusion Currently evidences suggest that repaglinide is superior to metformin for treating MD with SFS.

Objective To analyze the causes of unplanned tracheal extubation in mechanically ventilated patients in the pediatric intensive care unit using quality management practices and observe the changes of extubation rates before and after implementing these practices.Methods In the first place,we set up quality management group in June 2014.Second,the team formulated a risk factor checklist for unplanned tracheal extubation based on literature research, and analyzed the main causes requiring tracheal extubation. The last time,we developed some management measures for important reasons in 2014,and established and implemented a quality management strategy between 2015 and 2016.The incidence frequency of unplanned tracheal extubation,i. e. the number of extubation cases per 100 days with a tube in place(mechanical ventilation days),was used to evaluate the change of the extubation rates before and after implementing the new measures. The cases in 2014 were retrospectively analyzed,and cases from 2015 to 2016 were prospectively collected.The number of interval days for two continuity unplanned extubation was considered to be a means of quality control.Results Rick factors associated with unplanned extubation in the pediatric intensive care unit before implementing quality management were a delay of the replacing adhesive bandage, lack of sedation assessment,which were related to frequent physician replacement and insufficient training and supervision.In consideration of the identified risk factors,a standard operating procedure was formulated to prevent unplanned extubation,including standard operating procedure of tracheal catheter fixation and the sedation assessment. There were 484 mechanical ventilation in 2014,and the incidence of unplanned extubation was 0.8%,and the median number of days of separation was 8.0(4,20) d.Between 2015 and 2016,there were 1 379 mechanical ventilations,and the incidence of unplanned extubation was 0.2%,and the median number of days of separation was 34.0(19,61) d.The incidence of unplanned extubation in 2015 to 2016 was lower than that in 2014(χ2=5.936,P=0.018).Ramsay scoring usage increased from 28.6% in 2014 to 57.1% between 2015 and 2016,while Ramsay scored 3-4 points from 2015 to 2016 was higher than 2014(P< 0.05).Conclusion Establishing the quality management group according to the requirements of each hospital and implementing quality management strategies can reduce the incidence of unplanned extubation,thereby improving the quality of care in pediatric intensive care unit.

Objective: To evaluate the efficacy and safety of oseltamivir in the treatment of suspected influenza in children. Method: A multicenter, randomized and open-label trial was conducted among 229 individuals with suspected influenza which were collected from the clinic of 5 hospitals in Guangdong province (Guangzhou Women and Children′s Medical Center, Shenzhen Baoan District Maternity and Child Care Service Center, the Second Affiliated Hospital of Shantou University Medical College, Dongguan Maternity and Child Care Service Centre, Yuexiu District Children′s Hospital of Guangzhou) from April to July 2015. They were randomized either to oseltamivir group (oseltamivir 30-75 mg, twice daily for 5 days) or control group who were given symptom relief medicines for 5 days. Result: No significant difference was found between two groups in influenza symptoms of the patients before the treatment(P>0.05). Altogether 229 individuals (114 in oseltamivir group, 115 in control group) were analyzed for efficacy, in which 73 individuals (42 oseltamivir, 31 control), 31.9%, were identified as influenza-infected through laboratory test. No significant difference was found between the two groups in the duration of fever although shortened. In the 229 individuals , the cumulative alleviation proportion between oseltamivir and control group was not significantly different (P>0.05): the median duration of illness was 69.9 hours (95% CI 65.3-91.5) in oseltamivir group and 75.4 hours (95%CI 63.9-91. 7) in control group; the median duration of fever was 40.4 hours (95%CI 31.5-53.4) in oseltamivir group and 44.0 hours (95%CI 33.2-50.0) in control group. In the 73 individuals, the cumulative alleviation proportion between oseltamivir and control group was significantly different (P<0.05). The median duration of illness was 61.2 hours (95%CI 48.0-121. 0) in oseltamivir group, being significantly shorter than that of 116.0 hours (95%CI 91.5-175.0) in control group. But it was not significantly different that the median duration of fever was 32.8 hours (95%CI 24.0-47.0 ) in oseltamivir group and 55.8 hours (95%CI 43.6-78.3 ) in control group (P>0.05). And the median duration of fever in 60 individuals (38 oseltamivir, 22 control) was significantly different between two groups(P<0.05), who had finished a course of taking oseltamivir in the 73 individuals, 34.8 hours (95%CI 24.0-48.5 ) in oseltamivir group being significantly shorter than that of 53.3 hours (95%CI 43.6-104.0 ) in control group. There was certain difference in side effects rate between the two groups (oseltamivir 10%, control 2%, P<0.05). The main side-effects were gastrointestinal symptoms (stomachache, diarrhea, poor appetite, vomiting). Conclusion The duration of illness and fever in suspected influenza patients treated with oseltamivir was shorter than those in the patients treated with no oseltamivir, the difference was not statistically significant, when 31.9% was confirmed with positive result of virus test in suspected influenza in children. But in these patients with positive result of virus test, the duration of illness was significantly shortened with treatment with oseltamivir as compared with no treatment with oseltamivir, and it would be better if full oseltamivir course was completed for reducing the duration of fever. Oseltamivir treatment was safe with mild side effects.
