Abstract:In recent years,the outbreak and prevalence of respiratory infectious diseases in the world seriously endanger
human health,among which the respiratory infectious diseases caused by viral infection account for a large proportion. The
use of vaccines and common antiviral drugs is an effective way to fight viral infection,but there are also problems such as lag
and drug resistance. Monoclonal antibodies against respiratory viral infections provide a new strategy for clinical
treatment. This paper reviews the development of monoclonal antibody against respiratory virus and its application in
respiratory viral infectious diseases.

OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis of vertebral artery type (CSA) treated with thermosensitive moxibustion at different dosages.
METHODSSixty cases of CSA were randomized into a saturated moxa dosage group and a regular moxa dosage group, 30 cases in each one. The thermosensitive moxibustion was adopted in the two groups. The mild suspended moxibustion was applied at two acupoints with the strongest thermosensitization. In the saturated moxa dosage group, the moxibustion time was determined by the disappearance of thermosensitization. In the regular moxa dosage group, 15 min was required on each acupoint. The treatment was given twice a day for first 4 days in the two groups. Since the 5th day, the treatment was given once a day, continuously for 10 times, and totally 14 days were required. The score of symptoms and function and clinical efficacy were compared between the two groups before and after treatment as well as 6-month follow-up after treatment.
RESULTSThe curative and effective rate was 56.7% (17/30) after treatment and 60.0% (18/30) in 6-month follow-up after treatment in the saturated moxa dosage group, which were superior to 26.7% (8/30) and 30.0% (9/30) in the regular moxa dosage group respectively (P < 0.01, P < 0.05). The scores of clinical symptoms and function after treatment and in follow-up were improved apparently as compared with those before treatment in both groups (all P < 0.01). The scores of clinical symptoms and function after treatment and in follow-up in the saturated moxa dosage group were increased much more apparently than those in the regular moxa dosage group (after treatment: 22.32 +/- 4.64 vs 17.43 +/- 3.21; in follow-up: 23.01 +/- 4.76 vs 18.32 +/- 2.13, both P < 0.01).
CONCLUSIONThe thermosensitization moxibustion of saturated dosage achieves the superior short-term and long-term efficacies in the treatment of CSA as compared with the regular moxibustion dosage.

In recent years, the study of autophagy in spinal cord injury (SCI) gradually becomes the hot spot. However, the function of autophagy in the injured spinal cord is still controversial. In order to further understand the role of autophagy after SCI, we summarized the activation of autophagy, autophagic cell death, the relationship between autophagy and apoptosis, the function of autophagy in promoting the molecular metabolism and the role of autophagy after spinal cord injury. We concluded that the role of autophagy after SCI is a double-edged sword. Upregulating the level of autophagy appropriately can promote damaged proteins metabolism and inhibit apoptosis. However, excessive activation of antophagy may induce autophagic cell dealth. So we consider that the proper regulation of autophagy will be a new target in the treatment of SCI.
