Human a Type Genetic Engineering Interference Essence Injection

The highest-level interference essence against virus and turnour genetic engineering medicine is a new type created in the 1980s. Compared with chemical medicines, the interference essence has a special effect in the treatment of viruses and tumours. The human a, type genetic engineering interference essense is prepared by the Institute of Viruses of the Chinese Academy of Preventive Medical Sciences, the Shanghai Vaccine

Observation on clinical effect of botulinum toxin type A injection combined with low-energy CO2 fractional laser periocular rejuvenation treatment

Objective To investigate the clinical effect of botulinum toxin type A injection combined with low-energy CO2 fractional laser periocular rejuvenation treatment.Methods The clinical effect of botulinum type A injection alone and botulinum type A injection combined with low-energy CO2 fractional laser was compared in 96 patients who needed to receive periocular rejuvenation treatment from April 2018 to April 2019.Results After the combined low-energy CO2 fractional laser treatment was given on the basis of botulinum toxin type A injection,the follow-up global aesthetic improvement scale(GAIS)scores of the observation group were 86.78±4.67,80.31±3.66,76.94±4.03 and 40.59±4.78.The global aesthetic improvement of the dynamic and static wrinkles was obvious.The total effective rate was 93.7%.The total satisfaction rate of the patients was 95.8%,which was higher than that of the control group(P<0.05).The clinical efficacy was significant.Conclusion The application of the combined periocular rejuvenation treatment can improve the dynamic and static wrinkles simultaneously with remarkable rejuvenation effect,increase the effective rate of treatment and enhance the patients'satisfaction.

Effect of Botubinum toxin type A injection into the masseter muscle on mandibular development in rats

Objective To investigate the effect of Botulinum toxin type A(Botox)injection into the masseter muscle on mandibular development in rats.Methods 1228-day-old Wistar rats were divided into two groups as Botox group(n=6)and control group(n=6)

Safety Observation Study on Haemophilus Influenza Type B Conjugate Vaccines Injected at Different Sites in Chinese Infants

In the present study, the safety of Hoemophilus influenza type b conjugate vaccines inoculated in the upper arm deltoid and vastus lateralis muscle was evaluated. 680 infants aged 2-5 months and 6-12 months were selected to be the research subjects in whom the Hib conjugate vaccines were inoculated by injection in the upper arm deltoid and vastus lateralis muscle, respectively. The safety analysis indicated that there were no statistic differences in the incidence rates of adverse reactions when the Hib conjugate vaccines were inoculated at different sites. So we concluded that the safety of inoculation injection of Hib conjugate vaccines in vastus lateralis muscle was the same as that inoculated in the upper arm deltoid.

Relationship between iNOS expression and apoptosis in cerebral tissue, and the effect of Sini injection in endotoxin shock rats

OBJECTIVE: To investigate the dynamic changes and relationship of inducible nitric oxide synthase (iNOS) and apoptosis in endotoxin shock rats, as well as the effects of Sini injection. METHODS: In total, 102 Sprague-Dawley (SD) rats were randomly divided into a normal group (n=6, NG), sham operation group (n=24, OG), model group (n=24, MG), dexamethasone group (n=24, DG), and Sini group (n=24, SG). The endotoxin shock model was induced by an intravenous injection of lipopolysaccharide (LPS) (8 mg/kg). Rats in the OG, MG, DG, and SG groups were further divided into 4 groups: 1, 2, 3 and 6 h after shock groups (n=6 per group). iNOS expression was detected by immunohistochemistry. Terminal Deoxynucleotidyl Transferase Mediated Deoxyuridine Triphosphate-biotin Nick End Labeling was employed to measure apoptosis. RESULTS: No iNOS expression was found in the OG group. Compared with the OG group, iNOS expres-sion in the MG group was markedly elevated, reached a peak at 1 h (P<0.01), decreased at 2 and 3 h, and rebounded at 6 h. Compared with the MG group, iNOS expression decreased significantly in both the DG (P<0.05) and SG (P<0.01) groups at 6 h. Thenumberofapoptoticcellsin the MG group was markedly increased than that in the NG and OG (P<0.01) groups, and reached a peak at 6 h. The number of apoptotic cells in the DG group at 1 and 2 h (P<0.01) and SG group at 2, 3 and 6 h (P<0.01) decreased when compared with the MG group. CONCLUSION: Sini injection can significantly inhibit NO generation, which decreases apoptosis and subsequently protects the brain from endotoxic shock.
