ObjectiveTo observe the clinical efficacy of Anshen Buxin Gao in patients with coronary artery disease （CAD） complicated with somatization disorder after percutaneous coronary intervention （PCI）， as well as its effect on heart rate variability （HRV）. MethodsA total of 96 patients with somatization disorder after PCI were selected and randomized into control and treatment groups （48 cases）. On the basis of standardized Western medical treatment for CAD， the control group received Dailixin， while the treatment group received Dailixin combined with Anshen Buxin Gao. The somatic symptom scale （SSS）， generalized anxiety disorder 7-item scale （GAD-7）， patient health questionnaire-9 （PHQ-9）， and self-rating scale of sleep （SRSS） scores in both groups were recorded before and after treatment. The traditional Chinese medicine symptom efficacy， HRV， and incidence of adverse drug reactions were observed. ResultsA total of 90 patients completed the trial， encompassing 45 patients in the control group and 45 patients in the treatment group. Baseline characteristics between the two groups showed no statistically significant differences， indicating comparability. After treatment， both groups exhibited reductions in SSS， GAD-7， and PHQ-9 scores （P<0.05）， and the treatment group outperformed the control group in alleviating somatic symptoms and anxiety-depression symptoms （P<0.05）. The control group did not achieve a significant reduction in SRSS score， whereas the treatment group effectively lowered the SRSS score （P<0.05）. Regarding traditional Chinese medicine symptom efficacy， the total response rate in the treatment group was 91.1% （41/45）， which was higher than that （71.1%， 32/45） in the control group （Z=-2.663， P<0.05）. Both groups improved HRV in patients with somatization disorder， and the treatment group showed greater improvement （P<0.05）. There were no serious clinical adverse events during the study period. The incidence of adverse reactions in the treatment group was 6.7% （3/45）， which was lower than that （14/45， 31.10%） in the control group （χ²=7.252， P<0.05）. ConclusionThe addition of Anshen Buxin Gao to Dailixin therapy significantly alleviates the clinical symptoms and improves the sleep quality， treatment efficacy， and HRV in patients with CAD complicated with somatization disorder after PCI， while reducing the adverse effects associated with Dailixin alone. This approach demonstrates considerable clinical value and warrants further promotion.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

Objective:To compare the clinical efficacy of ultrasound-guided closed reduction and bare-handed reduction on pediatric distal radius fractures.Methods:Clinical data of 118 consecutive pediatric patients with distal radius fracture treated in the Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science & Technology from April 2018 to August 2019 were retrospectively analyzed.Patients treated with bare-handed reduction and ultrasound-guided closed reduction were respectively classified into group Ⅰ (58 cases) and group Ⅱ (60 cases). Baseline characteristics, treatment duration, out-patient treatment cost, postoperative pain and the modified Mayo wrist function score during the follow-up visits between groups were compared by the t test.The success rate of initial reduction, reduction times, hospitalization rate and complication between 2 groups were compared by the Chi- square test.The number of postoperative imaging scans between 2 groups was compared by the Mann- Whitney U test. Results:There were no significant differences in out-patient treatment cost and hospitalization rate between 2 groups (all P>0.05). There were significant differences in the length of stay [ (166.2±54.8) min vs.(142.6±49.2) min], success rate of initial reductions [72.4%(42/58 cases ) vs.88.3%(53/60 cases)], incidence of repeated reductions (27.6% vs.1.7%) and the incidence of postoperative repeated imaging scans (20.7% vs.1.7%) between groupⅠ and group Ⅱ (all P<0.05). A total of 104 patients (88.1%) were successfully treated with closed reduction and followed up, with a rate of success reductions.Among them, success rate of closed reduction in group Ⅰ and Ⅱ were 86.2% and 90.0%, respectively.The mean time of fracture healing was 43 (34-56) days.There were no significant differences in fracture healing time and pain score between 2 groups(all P>0.05). The modified Mayo wrist score was significantly lower in group Ⅰ than that of group Ⅱ[(97.3±4.1) points vs.(98.8±2.9) points, P<0.05]. Seven patients in group Ⅰ suffered fracture re-displacement, including 6 cases within 1 case week and 1 within 2 weeks, and 4 cases admitted to the surgical ward for further management.Five patients in group Ⅱ had re-displacement within 1 week of plaster fixation, of which 2 cases admitted to the surgical ward for further management, which was comparable between groups( P>0.05). Conclusions:Both ultrasound-guided closed reduction and bare-handed reduction are effective on the treatment of pediatric distal radius fractures, showing low incidence of complications and satisfactory functional results.Owing to its higher success rate of initial reduction, lower frequency of postoperative ra-diography and shorter length of stay, ultrasound-guided closed reduction should be recommended.

Fourteen batches of samples were analyzed to establish the fingerprint with paeonol and paeoniflorin as reference. Results The results of the 14 batches of samples and similarity evaluation showed that the similar degrees to the 10 batches among the 14 samples were between 0.968-0.998, which illustrated the good similar degrees among samples. Conclusion The established fingerprint with characteristics of stability, good reproducibility and simplicity, can be used for the quality evaluation and control of cortex moutan.

Objective To survey the incidence of sleep disorders among patients with industrial injuries and analyze the relevant factors.MethodsA total of 112 depressed patients ( male 106,female 6; aged 22-79 years,course of disease 35 d-25 years) were assessed by a professional psychologist using life satisfaction index A,the type A behavior pattern scale,the Pittsburgh sleep quality index (PSQI) and the Barthel index.ResultsThe incidence of disordered sleep was 40.18％ (45/112),of whom mildly depressed patients were 34.29％,moderately depressed patients 42.86％ and severely depressed patients 85.71％.The incidence of sleep disorders increased with increasing depression severity.The incidence of disordered sleep was significantly higher among the severely depressed patients than among those mildly or moderately depressed,but there was no significant difference in incidence between moderately and mildly depressed patients.PSQI scores among the severely and moderately depressed patients were significantly higher than among those mildly depressed,but there was no statistically significant difference in average PSQI scores between the severely and moderately depressed patients.The sleep disorder group suffered significantly poorer sleep quality and took significantly longer to get to sleep.There were no significant differences in average age,educational level,marital status,social relations,family and social support,gender distribution or course of disease between the two groups.There were,however,significant differences in family income,life satisfaction,character type and disease species between the groups.ConclusionThe incidence of disordered sleep among depressed patients after industrial injury is correlated with the severity of depression,family income,life satisfaction,the type of injury and the patient's character.

Objective To discuss the feasibility and value of routine clinical preoperative examination predicting benign and malignant thyroid nodules. Methods The clinical data of 1630 patients undergoing thyroidectomy for nodular thyroid disease were analyzed retrospectively.The relationship between pathological diagnosis and physical examination,ultrasonographic parameters,the results of laboratory test and nuclear medicine test were examined to build a risk prediction model.The sensitivity,specificity and accuracy of the formula were tested. Results In 387 cystic nodules 0.78％ were malignant; In 1243 solid nodules 17.2％ were malignant.Among the 1243 cases,characters significantly related to malignancy were:age younger than 40 years,solitary lobe involvement,hypoechoic nodule,irregular margins,solid nodule,microcalcification,macrocalcification,max diameter ≤ 2 cm. The prediction formula was: malignancy indicator =0.80 × age + 0.59 × solitary lobe + 0.72 × hypoechoic + 0.82 × irregular margin + 1.32 × solid nodule + 1.90 × microcalcification + 0.70 × macrocalcification + 0.71 × max diameter.The threshold limit value was 2.8,and the sensitivity,specificity and accuracy of which were 74.4％,80.4％ and 75.2％,respectively. Conclusions Benign and malignant thyroid nodules could be differentiated roughly with the combination of patients' general information and the results of routine examination before operation.
