Objective:To research the anti-inflammatory effect of LL-37 in mycobacterium tuberculosis ( Mtb ) infected-macrophages,as well as its influence on the secretion of inflammatory cytokines. Methods:( 1 ) THP-1 cells were cultured and incubated with phorbol 12-myristate 13-acetate (PMA) to transform into an adherent macrophage-like state (macrophage,Mφ). Then the THP-1 cell derived macrophages were infected with mycobacterium tuberculosis,and then stimulated with different concentrations of LL-37. (2)The experiment was divided into following groups: ① Control group:THP-1+normal saline (NS);② Mtb group:THP-1+Mtb;③Mtb+LL-37 5 μg/ml group:THP-1+Mtb+5 μg/ml LL-37;④Mtb+LL-37 10 μg/ml group:THP-1+Mtb+10 μg/ml LL-37;⑤Mtb+LL-37 20 μg/ml group:THP-1+Mtb+20 μg/ml LL-37. (3) The mRNA expression levels of IL-12p40,TNF-α,IL-4,and IL-10 will be determined by Real-time PCR respectively at 6,12,24 and 48 hours. The secreted levels of IL-12p40,TNF-α,IL-4,and IL-10 will be determined by ELISA analysis respectively at 6,12,24 and 48 hours. Results:The mRNA expression levels and secreted levels of IL-12p40,TNF-α,IL-4 and IL-10 were increased in Mtb group than those in control group. The mRNA expression levels and secreted levels of pro-inflammatory cytokines IL-12p40 and TNF-α were decreased in the LL-37 groups than those in Mtb group. However,anti-inflammatory cytokines IL-4 and IL-10 mRNA expression levels and secreted levels were increased in the LL-37 groups than those in Mtb group. Conclusion:Exogenous LL-37 inhibited the secretion of inflammatory cytokines in macrophages during mycobacterium tu-berculosis infection. The effect is related to the concentrations of LL-37 and the stimulated time of macrophages which were infected with mycobacterium tuberculosis. The results will provide new insights into the treatment of Mtb infection.

Objective To prepare a harmine hydrochloride liposome formulation with high encapsulation efficiency. Methods Preformulation investigation was carried out to obtain the drug physicochemical properties such as solubility and lgD in buffers of different pH value. Harmine hydrochloride was encapsulated into liposomes by active loading method. Encapsulation efficiency of liposomes was determined after the free drug was separated from liposome by ultrafiltration. The influence factors on the encapsulation efficiency including drug-lipid weight ratio, incubation temperature, pH value of external water phase were investigated. Results As the pH value increasing, the solubility of harmine hydrochloride was decreased, while the apparent oil-water distribution coefficient was increased. By active loading method, the encapsulation efficiency could be over 80% when the drug to lipid weight ratio was under 1∶5. The pH gradient between intervesicle and intravesicle obviously influenced the encapsulation efficiency, while incubation temperature had little effect on encapsulation efficiency. Conclusion Active loading is suitable for preparing harmine hydrochloride liposome with high encapsulation efficiency.

Objective To observe the effect of alteplase intra-arterial thrombolysis combined with continuous monitoring of transcranial Doppler (TCD) in patients with acute cerebral infarction. Methods Fifty-four patients with acute cerebral infarction were divided into TCD group and control group by random digits table method. The patients of 2 groups were given alteplase intra-arterial thrombolysis, and the patients of TCD groups were combined with continuous monitoring of TCD. The degree of clinical neurologic impairment was evaluated by National Institutes of Health stroke scale (NIHSS) and Barthel index (BI). The condition of vascular recanalization was evaluated by the change of blood flow signal of TCD. CT was performed within 1 d after thrombolysis to detect intracranial hemorrhage and other adverse reaction. The degree of clinical neurologic impairment, blood vessel recanalization rate after thrombolysis and recanalization time and incidence of intracranial hemorrhage and other adverse reaction were compared between 2 groups. Results There were no statistical difference in NIHSS score before thrombolysis and 1 h after thrombolysis between 2 groups (P>0.05). The NIHSS scores 7 and 30 d after thrombolysis in TCD group were significantly lower than those in control group:(8.1 ± 4.9) scores vs. (12.1 ± 4.2) scores and (6.9 ± 3.1) scores vs. (10.9 ± 3.9) scores, there were statistical differences (P<0.05). The BI scores 7 and 30 d after thrombolysis in TCD group were significantly higher than those in control group: (78.5 ± 13.8) scores vs. (60.8 ± 12.4) scores and (82.6 ± 13.5) scores vs. (63.2 ± 12.9) scores, and there were statistical differences (P<0.05). The blood vessel recanalization rate 24 h after thrombolysis in TCD group was significantly higher than that in control group: 70.4% (19/27) vs. 44.4% (12/27), the recanalization time after thrombolysis was significantly shorter than that in control group: (36.4 ± 9.5) min vs. (58.5 ± 12.4) min, and there were statistical differences (P<0.05). No adverse reaction like intracranial hemorrhage and so on was found by CT detection within 1 d after thrombolysis in the 2 groups. Conclusions Alteplase intra-arterial thrombolysis combined with continuous monitoring of TCD in acute cerebral infarction has good curative effect, and no obvious adverse reaction.

Objective To observe the clinical efficacy of comprehensive muscle-region therapy based on Chuang Medicine in treating cervical spondylosis of neck type.Method A hundred patients with cervical spondylosis of neck type were randomized into a treatment group and a control group, 50 cases in each group. The treatment group was intervened by the comprehensive muscle-region therapy based on Chuang medicine (muscle-region tuina, fire-needle acupuncture of Chuang medicine, and cupping), while the control group was by regular acupuncture treatment. The Visual Analogue Scale (VAS) score and symptoms and signs scores were observed before and after intervention, and the clinical efficacies were compared.Result The VAS scores respectively after 1 and 2 treatment courses were significantly different from that before intervention in the treatment group (P<0.05,P<0.01).
