OBJECTIVE:To provide reference for the evolvement of the current drug marketing license system in China. METHODS: The registry classification, the drug registration procedure and the combination of marketing license and production license both at home and abroad were analyzed comparatively. In addition, the necessity and feasibility of the drug marketing license system in China were analyzed. RESULTS & CONCLUSIONS: The current drug marketing license system that centered on license No. goes against the investigation of legal ability, drug administration mode, medicine technology transfer system and original equipment manufacture thus remains be reformed. There is still difficulty for the enforcement of drug marketing licensor system, yet it should be carried out step by step until its establishment.

The high-intensity interval training often consisted of groups of interval high-intensity exercise of exhaustion or above 90%maximal oxygen consumption, which can be applied to improve aerobic capacity. Adaption of skeletal muscles might be resulted from high-intensity interval training, including recruitment, glucose metabolism and activity of mitochondrial oxidase, etc., and improve maxi-mum oxygen uptake. It has been used for physical fitness, such as weight reduction, rehabilitation of heart diseases and diabetes mellitus, etc.

Objective To investigate the clinical efficacy of mind- and qi-regulating acupuncture in treating postoperative gastroplegia.Methods Thirty-six patients with postoperative gastroplegia were randomly allocated to treatment and control groups, 18 cases each. The control group received conventional acupuncture and the treatment group, acupuncture at points for regulating mind and qi (Baihui, Sishencong and Yindang) in addition. Pre- and post-treatment Hamilton Depression Rating Scale (HAMD) scores and gastric drainage volumes, and the number of treatments and the recovery rate were recorded in the patients. Comparisons of them were made between the two groups.Results There was a statistically significant pre-/post-treatment difference in the HAMD score in the two groups (P<0.01). There was a statistically significant post-treatment difference in the HAMD score between the treatment and control groups (P<0.05). There was a statistically significant pre-/post-treatment difference in gastric drainage volume in the two groups (P<0.01). There were statistically significant differences in the number of treatments and the recovery and marked efficacy rate between the treatment and control groups (P<0.05).Conclusions Mind- and qi-regulating acupuncture helps recovery and can also reduce the number of treatments in gastroplegia patients.

OBJECTIVE To investigate the clinical characteristics and the present condition of infective diabetic foot. METHODS A total of 100 cases with infective diabetic foot were classified into the wet gangrene and composite gangrene, and treated by the systemic and local modality in combination. RESULTS The cure rate of the wet gangrene and composite gangrene was 29.5% and 18.2%, respectively and the effective rate was 83.3% and 68.2%, respectively. CONCLUSIONS The combined therapy is effective for the treatment of diabetic foot.

Objective To investigate the clinical characteristics and treatment of senile patients with lumbar disc protrusion . Methods The clinical data of 56 cases of senile lumbar disc protrusion from 1990 to 2000 were reviewed retrospectively. Results 48 patients had been followed for 6 months to 7.5 years with average 4 years. Excellent and good results were 41 cases (85.4%).Conclusions There was atypical symptom in the senile patients with lumbar disc protrusion. CT was an important methods for diagnosis. The after concomitant diseases were controlled, resecting half vertebral lamina and enlarging fenestration were performed. The therapeutic results were satisfactory.

Rheumatoid arthritis ( RA) was a common autoimmune disease characterized with main clinical manifestations of chronic inflammation in joints.Anti-carbamylated proteins(anti-CarP)antibody, as a promising bio-marker, played a crucial role in the diagnosis of RA patients and the screening of pre-RA patients .In this article , recent progress on the study of anti-CarP antibody and RA related diseases has been reviewed , which was expected to provide new references for the diagnosis and treatment of related clinical diseases .

BACKGROUND:Host immune rejection is the main problem for nerve alograft in the repair of nerve defects. Therefore, how to avoid and minimize the immune rejection is the key to the success of nerve alografting. OBJECTIVE: To develop a new nerve pretreatment method by which Schwann cels and myelin can be removed from the peripheral nerve of dogs while the basilar membrane can be reserved integraly in order to obtain acelular nerve alografts. METHODS:Bilateral sciatic nerves from healthy adult dogs were taken and pretreated with the combined freeze-thaw and chemical methods folowed by microscopic observation of ultrastructural features, histological staining and western blot analysis of its ingredients. RESULTS AND CONCLUSION:Pretreated acelular nerves with good ductility and excelent epineurium toughness were empty basal lamina tubes with no Schwann cels, myelin and fragments that were al removed thoroughly, but the basilar membrane was fuly retained. These findings indicate that the optimized combination of freeze-thaw and chemical methods can efficiently clear Schwann cels and myelin which are the major antigenic components in the peripheral nerve, while preserve the basilar membrane to promote nerve regeneration. Therefore, this method can be an ideal method for preparation of tissue engineered nerves.

Objective To observe the characteristics of macular optical coherence tomography (OCT) changes before and after silicone oil removal in patients who had undergone pars plana vitrectomy with silicone oil tamponade for macula-off rhegmatogenous retinal detachment (RRD).Methods Thirty-nine eyes that underwent silicone oil removal were enrolled in this retrospective study.The patients included 24 males and 15 females,with an average age of (53.05±4.03) years,the duration of silicone oil tamponade ranged from 3 to 7 months.Best-corrected visual acuity,intraocular pressure,slit lamp microscope and prelens,indirect ophthalmoscopy and fourier domain OCT were measured for all patients before and at months 1,3 and 6 after silicone oil removal.The macular microstructure were observed before and after silicone oil removal.Results Submacular fluid was detected in 6 eyes (15.38％),at the last time of follow-up,submacular fluid resolved completely in 2 eyes with disrupted ellipsoid zone,and resolved partly in 2 eyes.Disrupted ellipsoid zone were observed before silicone oil removal in 16 eyes (41.02％),6 eyes showed simultaneous disrupted ellipsoid zone and disrupted external limiting membrane,and there were 2 eyes that external limiting membrane was not identified,at the last time of follow-up,disrupted ellipsoid zone restored in 2 eyes and the extent of disrupted ellipsoid zone became reduced in 4 eyes.Cystoids macular edema were found in 2 eyes (5.12％),it resolved completely in 1 eye and resolved partly in 1 eye at the last time of follow-up.Macular epiretinal membrane was detected in 10 eyes (25.64％),and macular epiretinal membrane was found before silicone oil removal in 5 eyes,at the last time of follow-up,the membrane became thickened in 2 eye;5 eyes developed macular epiretinal membrane after silicone oil removal,at the last time of follow-up,the membrane became thickened in 1 eye.Secondary macular hole were noted in 2 eyes.Microcystic macular changes were observed in 9 eyes (23.07％),it was observed in 7 eyes before silicone oil removal,and was observed in 2 eyes after silicone oil removal,at the last time of follow-up,the cysts reduced in 1 eye.Conclusion Submacular fluid,disrupted ellipsoid zone and microcystic macular are the main macular ultrastructural changes that developed in patients with RRD before and after silicone oil removal.
