OBJECTIVE:To investigate the medication safety status of Chinese patent medicines and related influence factors for residents in Guangdong province,and provide reference for better guarantee of medication safety for residents. METHODS:Questionnaires were randomly sent out among the residents in 3 cities of Guangdong province. The cognition,utilization habit and safety awareness,the ways to get the related information of Chinese patent medicines and purchase way were surveyed and ana-lyzed statistically. RESULTS:Totally 530 questionnaires were sent out and 514 valid questionnaires were collected with effective re-covery of 96.98%. There are 64.01% of respondents didn’t know the composition of Chinese patent medicines;50.39% didn’t know the contraindications of Chinese patent medicines;48.44% didn’t know the adverse drug reactions of Chinese patent medi-cines that they were using;23.47% had once broken the tablets when took them;65.18% didn’t know that the old people had less dosage than teenagers and 44.75% didn’t know that Chinese patent medicines couldn’t be taken with some western medicines. There were many ways to get the related information of Chinese patent medicines and purchase them,and the main sources were from doctors and pharmacists in drug stores;90.08% had purchased Chinese patent medicines in drug stores. CONCLUSIONS:During daily medication of Chinese patent medicines,the biggest problem for residents is that the weak awareness of medication safety,unreasonable medication behavior and habit caused by lack of related knowledge of medication safety,which may cause safety risks or happen medication safety problems. Therefore,the residents’education of self-medical knowledge should be intensi-fied,the management of prescription in drug stores should be enhanced,pharmaceutical service function of pharmacists should be played,supervision management of drug advertisement should be strengthened and the contents in drug instructions should be regu-lated.

Objective To evaluate effect of combined corpeetomy for multilevel cervical spondylotic myelopathy (CSM) and ossified posterior longitudinal ligament (OPLL).Methods Fifteen patients with CSM or OPLL,including 9 males and 6 females,were treated with combined corpectomy which is characterized by C4 and C6 corpectomy,excision of osteophyma,protruded disc and/or ossified posterior longitudinal ligament on basis of preservation of C5 vertebral body,structural bone grafting in C3-5 and C5-7,and anterior cervical plate fixation at C3,C5,and C7.The clinical results were evaluated with Japanese Orthopaedic Association (JOA) score.X-rays and CT scans were taken to evaluate vertebral fusion,and MRI was used to access spinal canal decompression and condition of spinal cord.Results All patients were followed up for 9 to 42 months (average,26.7 months).Bony fusion was achieved in all 15 patients.The JOA score improved from preoperative 13.44±2.81 to postoperative 16.16±2.19 (P=0.0354).The cervical lordosis improved from preoperative 1.16°±11.74° to immediately postoperative 14.36°±7.85° (P=0.00217),and 12.92°+6.17° at the final follow-up (P=0.00292).The complications included temporary hoarseness in 2 cases,dysphagia in 1 case.Conclusion The combined corpectomy for treating CSM and OPLL can obtain reliable and satisfactory results.In operation,the preservation of C5 vertebral body can provide an additional screw anchoring force and strengthen stahility.

Background::Electroacupuncture (EA) has been shown to attenuate airway inflammation in asthmatic mice; however, the underlying mechanism is not fully understood. Studies have shown that EA can significantly increase the inhibitory neurotransmitter γ-aminobutyric acid (GABA) content in mice, and can also increase the expression level of GABA type A receptor (GABAAR). Furthermore, activating GABAAR may relieve inflammation in asthma by suppressing toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-kappa B (NF-κB) signaling pathway. Therefore, this study aimed to investigate the role of GABAergic system and TLR4/MyD88/NF-κB signaling pathway in asthmatic mice treated with EA.Methods::A mouse model of asthma was established, and a series of methods including Western blot and histological staining assessment were employed to detect the level of GABA, and expressions of GABAAR and TLR4/MyD88/NF-κB in lung tissue. In addition, GABAAR antagonist was used to further validate the role and mechanism of GABAergic system in mediating the therapeutic effect of EA in asthma.Results::The mouse model of asthma was established successfully, and EA was verified to alleviate airway inflammation in asthmatic mice. The release of GABA and the expression of GABAAR were significantly increased in asthmatic mice treated with EA compared with untreated asthmatic mice ( P < 0.01), and the TLR4/MyD88/NF-κB signaling pathway was down-regulated. Moreover, inhibition of GABAAR attenuated the beneficial effects of EA in asthma, including the regulation of airway resistance and inflammation, as well as the inhibitory effects on TLR4/MyD88/NF-κB signaling pathway. Conclusion::Our findings suggest that GABAergic system may be involved in mediating the therapeutic effect of EA in asthma, possibly by suppressing the TLR4/MyD88/NF-κB signaling pathway.

OBJECTIVE: To determine the characteristics, classification, and treatment of thoracic fracture accompanied with sternum fracture. METHODS: Data of 32 patients with thoracic fractures accompanied with sternum fracture were reviewed. Patients information such as age, gender, cause of injury, site of sternum fracture, level and type of thoracic vertebral fracture, spinal cord injury and associated injuries was included in the analysis. Of the 32 patients, 13 had compressed fractures, 13 had fracture-dislocations, 5 had burst fracture and 1 had burst-dislocation. Six patients had a complete lesion of the spinal cord, 13 sustained a neurologically incomplete injury, and the other 13 were neurologically intact. Ten patients were treated nonoperatively and the other 22 surgically. RESULTS: All patients were followed up for 10-103 months. Road traffic accidents and falling dominated among the causes. All patients were accompanied with other injuries. None of the 6 patients with a complete paralitic lesion regained any significant function. Of the 13 neurologically intact patients, 5 had local pain although 12 of them remained normal function. One patient showed tardive paralysis. Three of the 13 patients with incomplete paraplegia returned to normal, 5 regained some function and 5 did not recover. CONCLUSION Thoracic fractures accompanied with sternum fracture are marked by violent force, severe fracture of the spine, severe injuries of the spinal cord, and high incidence of other injuries. The new classification method is more suitable to thoracic fractures accompanied with sternum fracture,and confirms the existence and clinical relevance of the 4th column of the thoracic spine and its role in providing spinal stability in patients with thoracic fracture.
