Objective: To observe the clinical efficacy of application in canicular days plus enteral nutrition in treating cough variant asthma (CVA) in kids, and to explore its action mechanism. Methods:Following a randomized controlled single-blind parallel-group design, 138 eligible kids with CVA were randomized into an observation group, a canicular-day application group, and an enteral nutrition group, 46 kids in each group. The canicular-day application group was intervened by application in canicular days, the enteral nutrition group was by enteral feeding, and the observation group was by both canicular-day application and enteral feeding. The therapeutic efficacies were evaluated after a treatment course. Results: The recovery rate and total effective rate were respectively 50.0% and 98.0% in the observation group, versus 23.9% and 91.3% in the canicular-day application group, and 13.0% and 78.6% in the enteral nutrition group. The observation group was significantly superior to the other two groups (bothP<0.05). In comparing the global symptom score, peak expiratory flow (PEF), forced expiratory volume in one second (FEV1), CD3+, CD4+, CD4+/CD8+, CD8+, hemoglobin (Hb), total protein (TP), albumin (ALB), eosinophil cationic protein (ECP), lipid peroxide (LPO), leukotriene (LT), body weight (BW), triceps skin-fold (TSF), and arm muscle circumference (AMC), the observation group was significantly better than the other two groups (bothP<0.05). Conclusion:Application in canicular days plus enteral nutrition can significantly improve the pulmonary function and symptoms in children’s CVA, and the effect is possibly produced by regulating cellular immune system, enhancing Hb, TP, ALB, BW, TSF, AMC, and inhibiting the production of ECP, LPO, and LT.

Objective To analyze the cause of missing diagnosis for vertebral fracture on lateral chest radiography. Methods Lateral chest radiographies of 1638 hospitalized patients (871 males and 767 females) were retrospectively reviewed for identifying vertebral fractures. Their ages ranged from 50 to 91 years with the mean of 63.5 years. Complains and application for chest radiography in all patients were not related to osteoporosis and vertebral fracture. Vertebral fracture and fracture severity were evaluated using Genant's semiquantitative visual method, taking approximately a 20%-25% vertebral height reduction as mild grade,26%-40% as moderate grade and 41% or greater as severe grade. Evaluation results of the vertebral fracture, original X-ray reports, as well as medical records were compared for further analysis. Results Eighty-four in 1638 patients showed vertebral fractures on the lateral chest radiographies. Of them,vertebral fractures were reported in 30 cases and 54 patients were not reported on their original X-ray reports. There were 63 vertebral fractures in 54 un-reported patients, most of which were single fracture (75% or 47/63). Grade Ⅰ fracture accounted for 54% (34/63), Grade Ⅱ fracture 33% (21/63), while 13% presented grade Ⅲ fracture (8/63). In all 84 patients with vertebral fractures, only 5 cases (6%)underwent dual energy X-ray absorptiometry (DXA) measurement, 5 cases ( 6% ) were recorded to have vertebral fractures on the medical papers, as well as 15 cases ( 18% ) were prescribed drugs related to the osteoporosis when discharged from hospital All drugs prescribed for the 15 patients were limited only to calcium. Conclusions More attention should be paid to osteoporosis by doctors including radiologists.Vertebral fracture on lateral chest radiography should be completely diagnosed, which is helpful for both prevention and treatment.

Objective To investigate the efficacy of acupuncture and rehabilitation therapy on lower limb motor function, and to explore a cortical mechanism using functional near infrared spectroscopy (fNIRS). Methods From December, 2020 to July, 2021, 24 stroke patients with lower limb motor dysfunction in our hospital were randomly divided into rehabilitation group (n = 12) and acupuncture-rehabilitation group (n = 12), and received routine rehabilitation training and acupuncture-rehabilitation intervention for four weeks, respectively. The control group included ten healthy subjects matched the patients. Before and after intervention, the lower limb motor function of the patients was assessed with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and all the subjects accepted fNIRS examination. The functional intensity and lateralization index (LI) of supplementary motor area (SMA), premotor cortex (PMC) and sensory motor cortex (SMC) were calculated based on oxygenated hemoglobin (HbO2). Results There was no significant difference in FMA-LE score between the rehabilitation group and the acupuncture-rehabilitation group before the intervention (P > 0.05). After four weeks of intervention, FMA-LE scores improved in both groups (t > 3.770, P < 0.001), and improved more in the acupuncture-rehabilitation group than in the rehabilitation group (t = 2.252, P < 0.05). Before intervention, the average functional connection was more intensitive in the control group than in the two patients groups (P < 0.05), and there was no significant difference between the later two groups (t = 0.458, P > 0.05). After intervention, the average functional connection increased in both groups (t > 2.178, P < 0.05), and the functional connection of the affected PMC of acupuncture-rehabilitation group increased (P < 0.05). The LI in SMC increased in the acupuncture-rehabilitation group (P < 0.05). There was a significant positive correlation between the change of functional connection of the affected PMC and the change of FMA-LE scores in the acupuncture-rehabilitation group (r = 0.579, P < 0.05). Conclusion Acupuncture with rehabilitation therapy can significantly improve the lower limb motor function and asymmetrical activation of SMC in stroke patients. The recovery of lower limb motor function may be related to the enhanced activation of affected PMC.
