Objective:To investigate the inhibitory effects produced by combination of carboplatin ( CA) and Tanshinone ( TA) on the growth of B16.Methods:After the mice were injected B16 subcutaneously in the right thigh, the mice were divided into four groups,PBS group,TA group,CA group,and TA+CA group.Normal mice were set up as control.Mice of PBS group were injected 0.2 ml PBS intraperitoneally;mice of CA group were injected 0.5 mg CA intraperitoneally for four consecutive days and followed by four days without administration until the mice were killed;mice of CA+TA group were injected 0.5 mg CA intraperitoneally for four consecutive days and followed by four days without administration,TA (0.5 g/kg body weight) was administered to the mice through gastric injection every day until the mice were killed.Results:The tumor weight and volume of CA+TA mice were significantly smaller than those of CA mice,TA mice and PBS mice ( P<0.05 );the tumor weight and volume of CA mice were significantly smaller than those of TA mice and PBS mice (P<0.05).The body weight grow of TA+CA mice was more significant than that of TA mice and CA mice( P<0.05).Conclusion:Combination of carboplatin (CA) and Tanshinone (TA) will produce a better inhibitory effects on the growth of B16 cells.

Objective To explore the effect and mechanism of Toll-like receptor 4 (TLR4) on cerebral ischemia/reperfusion injury. Methods Rats were divided into a sham group, MCAO group, and MCAO+TAK group. Cerebral cortices were removed on day 1, 3, 7, and 14 post surgery. Morphological staining and Western blotting were used to detect pathological changes and TLR4 and P-IKKα/β expression in brain tissues. Results The pathological changes in the MCAO+TAK group were more severe than in the MCAO group on day 1 post surgery. However, the MCAO group exhibited more severe damage at the other time points. TLR4 expression was lowest in the cerebral cortices of the sham group. On day 1 and 14 post surgery, TLR4 expression was lower in the MCAO group than in the MCAO+TAK group, while on day 3 and 7 post surgery, TLR4 expression was higher in the MCAO group than in the MCAO+TAK group. P-IKKα/β expression was highest in the cerebral cortices of the MCAO group at all time points except for day 1. Conclusion TLR4 may alleviate cerebral ischemia reperfusion injury in rats on day 1 post surgery; however, TLR4 may exacerbate ischemia repeifusion injury 3 to 14 days post surgery. The mechanism may be due to the effect of P-IKKα/β expression in the cerebral cortex.

Objective:To observe the efficacy and safety of the M receptor antagonist Bencycloquidium bromide nasal spray in treatment of seasonal allergic rhinitis with runny nose as the main symptom. Methods:From August 2021 to September 2021, 134 patients with seasonal allergic rhinitis were enrolled in the otolaryngology Outpatient Department of Peking University Third Hospital, First Affiliated Hospital of Harbin Medical University and China-Japanese Friendship Hospital of Jilin University, including 71 males and 63 females, with a median age of 38 years. TNSS score and visual analogue scale(VAS) of total nasal symptoms were observed during 2 weeks of treatment with Bencycloquidium bromide nasal spray. Results:TNSS score decreased from (8.89±3.31) on day 0 to (3.71±2.51) on day 14(P<0.001), VAS score of nasal symptoms decreased from (24.86±7.40) on day 0 to (6.84±5.94) on day 14(P<0.001), VAS score of rhinorrhoea decreased from (6.88±2.06) on day 0 to (1.91±1.81) on day 14(P<0.001). Rhinoconjunctivitis quality of life questionnaire(RQLQ) score decreased from (94.63±33.35) on day 0 to (44.95±32.28) on day 14(P<0.001). The incidence of adverse reaction was low and no serious adverse events occurred during the whole experiment. Conclusion:Bencycloquidium bromide nasal spray has significant efficacy and good safety in the treatment of seasonal allergic rhinitis.
