Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Objective: To observe the therapeutic efficacy of acupoint application at different groups of acupoints in treating bronchial asthma in remission stage. Methods:A total of 120 patients with bronchial asthma in remission stage were recruited and divided by the random number table method into acupoint application group 1, acupoint application group 2 and acupoint application group 3, with 40 cases in each group. In all the three groups, Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) were selected, with Dingchuan (EX-B 1) added in acupoint application group 1, Shenshu (BL 23) added in acupoint application group 2, and Gaohuang (BL 43) added in acupoint application group 3. Before intervention, one month and 3 months after intervention, clinical symptoms, peak expiratory flow (PEF) andforced expiratory volume in 1 second percentage of predicted value (FEV1％) of the three groups were observed, and their clinical efficacies were evaluated. Results: Comparing the therapeutic efficacy regarding traditional Chinese medicine symptoms and signs, after 1-month treatment, the total effective rate was 87.5％ in acupoint application group 1, versus 62.5％ in acupoint application group 2 and 55.0％ in acupoint application group 3, and the between-group differences were statistically significant. After 3-month treatment, the total effective rate was 95.0％ in acupoint application group 1, versus 70.0％ in acupoint application group 2 and 65.0％ in acupoint application group 3, and the between-group differences were statistically significant. After intervention, the three groups all showed significant improvements in pulmonary function with statistical significance; among the three groups, the improvement in acupoint application group 1 was more significant than that in the other two groups. Conclusion: Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) as basic prescription plus Dingchuan (EX-B 1) can improve symptoms of bronchial asthma in remission stage, and it works better in improving pulmonary function than the basic prescription plus Shenshu (BL 23) or Gaohuang (BL 43).

Children with autism spectrum disorder(ASD)may suffer from motor skill dysfunction,and perform as motor delay,coordination disorder,fitness decline,visual-motor integration disorder and so on,which disturb their daily life,school-based activities,and other social activities. Due to the obvious core symptoms of children with ASD,the problem of motor skills may be ignored. Children with ASD should be monitored for the motor development at their early stage and be evaluated with proper assessment tools. Children with ASD should be trained with individualized plan according to their features in order to develop motor skills and improve the core symptoms. As evidence of motor intervention for children with ASD is increasing,we should pay more attention to the motor skill dysfunction problem in children with ASD and make them benefit from the motor intervention and sport program.

OBJECTIVETo study clinical effects of needle Dao for the treatment of carpal tunnel syndrome.

METHODSFrom July 2014 to December 2016, 60 patients with carpal tunnel syndrome were divided into two groups: needle Dao treatment group(treatment group), and brace and medicine treatment group(control group), 30 cases in each group. There were 8 males and 22 females in the treatment group, with an average age of (49.38±7.43) years old. There were 7 males and 23 females in the control group, with an average age of (50.23±8.71) years old. There were no statistically significant differences between two groups before treatment in age, sex, course of disease, sensory nerve conduction velocity (SCV), sensory nerve action potential (SNAP), and distal motor latency(DML). The patients in the treatment group were treated with needle Dao for 1 to 2 times, while the patients in the control group were given celecoxib, vitamin B1 and vitamin B12, with the brace fixed. After treatment, the changes of SCV, SNAP and DML in two groups were observed.

RESULTSAfter treatment, the SCV were (48.63±7.33) m/s and (41.24±6.15) m/s in treatment group and control group separately, the SNAP were (9.89±3.71) m/s and (8.22±2.19) m/s, and the DML were(5.11±2.28) m/s and (6.13±2.23) m/s. The SCV, SNAP and DML after treatment were better than those before treatment(<0.05). And the results of SCV, SNAP and DML of patients in the treatment group were better than those of patients in the control group(<0.001).

CONCLUSIONSNeedle Dao can effectively improve the overall treatment efficiency of patients with carpal tunnel syndrome and reduce the symptoms of patients, which is feasible and suitable to use in clinical.

Breast cancer has the highest incidence rate among all women's malignant tumors worldwide.Surgery,radiotherapy and chemotherapy are three major treatments,while most patients showed adverse effects or complications during or after the treatment,including lymphedema,gastrointestinal reactions and leukopenia,which cause severe impact on patients' recovery and quality of life.Moxibustion has been used and certified to alleviate adverse effects of surgery or chemoradiotherapy for breast cancer.We have summarized literatures in recent years and suggest more systematic research in the future for the underlying mechanism.

Objective:To observe the clinical effect of acupuncture for persistent allergic rhinitis (PAR).Methods:A total of 154 PAR patients were randomized into a treatment group and a control group,78 cases in the treatment group received acupuncture at meridian points,while 76 cases in the control group received acupuncture at non-meridian points.The treatment was done every other day,3 times a week for a total 4 weeks.The total nasal symptom score (TNSS),the total non-nasal symptom score (TNNSS) and the rhinoconjunctivitis quality of life questionnaire (RQLQ) were measured before the treatment and after 2 weeks and 4 weeks of treatment,as well as 1 month and 3 months after the treatment to compare the clinical effect between the two groups.Results:After 4 weeks of treatment,the total effective rate in the treatment group was 92.3％,versus 76.3％ in the control group,showing a statistically significant difference (P＜0.05).Intra-group comparisons of TNSS,TNNSS and RQLQ scores after 4 weeks of treatment showed statistically significant differences (all P＜0.05).Between-group comparisons of TNSS,TNNSS and RQLQ score after 4 weeks of treatment and in follow-up visits showed statistically significant differences (all P＜0.05).Conclusion:Acupuncture is effective for PAR,and acupuncture at meridian points can produce a better effect than acupuncture at non-meridian points.

Objectives: To compare the effect between the right ventricle to pulmonary artery connection and the systemic-to-pulmonary artery shunt palliative surgery in patients with pulmonary atresia and ventricular septal defect. Methods: A total of 92 consecutive patients (mean age [1.69 ± 1.72] years, range 0.2-8.1 years) diagnosed with pulmonary atresia, ventricular septal defect and pulmonary artery hypoplasia (Nakata index [87.51 ± 36.97] mm2/m2; McGoon ratio 0.97±0.28) from December 2009 to August 2012 in our hospital were included in this retrospective study. 45 patients underwent the procedure of right ventricle to pulmonary artery connection (RV-PA) and 47 underwent the systemic-to-pulmonary artery shunt surgery, some patients also received simultaneous transcatheter occlusion of major aortopulmonary collaterals and/or pulmonary angioplasty. The mechanical ventilation time and ICU monitoring time, the pulmonary vascular growth and the anatomical repair rate were compared between the two groups. Results: The mean follow up time was (2.01±1.02)years. Nakata index and McGoon ratio equally increased significantly post operation as compared to baseline level (P<0.001). Incidence of final anatomical repair was significantly higher in the RV-PA group than in the systemic-to-pulmonary artery shunt group (62.2% vs 31.9%,P<0.01). During the anatomical repair operation, the incidence of cyanosis improvement was significantly higher, while the operation time was significantly shorter in the RV-PA group than in the systemic-to-pulmonary artery shunt group(both P<0.05). Mechanical ventilation time and ICU monitoring time also tended to be shorter in the RV-PA group (P>0.05). Conclusions: The palliative right ventricle to pulmonary artery connection surgery is related to higher rate of final anatomical repair in patients with pulmonary atresia and ventricular septal defect and may help the patients recover after the anatomical repair.
