Tachykinins are potent mediators of many functions in the airways.The tachykinins substance P and neurokinin A,presenting in human airways,can be recovered from the airways after a series of stimuli.They interact in the airways with tachykinin Neurokinin1,Neurokinin2 and Neurokinin3 receptors to cause bronchoconstriction,plasma extravasation,mucus secretion and to attract and activate immune cells and inflammation cells.They play a important role in the pathophysiology of asthma.However,the application of tachykinin receptor antagonists in clinic has been rather slow and somehow disappointing and needs to be further studied.

Objective To explore the mechanism of vitamin E on delaying skin aging by observ-ing the expression of hyaluronic acid synthetase-2 (HAS-2) in human dermal fibroblasts in vitro. Methods Human skin fibroblasts were cultured in vitro, and these fibroblast cells were then divided into 3 groups: different concentration of vitamin E (0, 0.1 × 10-10, 1 ×109mol/L) was added in the medium in the different group. 24 hours later, the fibroblasts were collected, RNAs extracted, and then amplified by RT-PCR. The PCR product was determined by agarose gel electrophoresis, to analyze the level of HAS-2 mRNA expression. Results RT-PCR showed the lever of HAS-2 mRNA was higher in the low-dose group than the control group, with significant difference (P<0.05) ; the lever of HAS-2 mRNA was higher in the high-dose group than control group, with significant difference (P<0.05). There was no significant difference in the lever of HAS-2 mRNA between the low-dose group and the high-dose group. Conclusions Vitamin E can enhance the expression of hyaluronic acid synthetase-2 mRNA, may increase the synthesis of HAS in skin fibroblasts and increase water content in the skin, so that it might reverse or delay the skin aging.

OBJECTIVE To evaluate the anti-vertigo effect of phencynonate hydrochloride. METHODS To detect the improvement of phencynonate hydrochloride on cerebral blood flow, a rat model wa s es?tablished with bilateral common carotid arteries occlusion. Phencynonate hydrochloride 0.1-4.0 mg·kg-1 was ig given, twice a day for three consecutive days and the alteration of cerebral blood flow was measured with laser Doppler flowmetry. Rotating acceleration equipment was used to provocate mouse vertigo for 30 min, and the spontaneous locomotor activities were tested for occurrence of vertigo in mice. Phencynonate hydrochloride 1.4-5.6 mg·kg-1 was ig given before rotating acceleration. Gastric phenol red emptying rate was used to determine the anti-nausea effect of the test drug in mice 30 min after phencynonate hydrochloride 1.4-8.4 mg·kg-1 was ig given. RESULTS The cerebral blood flow of the rat model with bilateral common carotid arteries occlusion was reduced significantly after 24 h (P<0.01). Compared with the model group, phencynonate hydrochloride (0.5, 2.0 and 4.0 mg · kg-1) increased the cerebral blood flow in a dose-dependent manner in rats with cerebral ischemia (P<0.01). The spontaneous locomotor activities were significantly reduced after vertigo stimulation in mice (P<0.05). Compared with the model group, phencynonate hydrochloride (2.8 and 5.6 mg · kg-1) increased the movement distance and speed of vertigo mice (P<0.05). Phencynonate hydrochloride (2.8, 5.6 and 8.4 mg·kg-1) inhibited the gastric emptying of mice (P<0.05). CONCLUSION Phecynonate hydrochloride can improve the cerebral blood flow and locomotor activities in vertigo rats, while inhibiting gastric emptying, which points to the therapeutic potential of phencynonate hydrochloride for vertigo in clinic.

Objective: Our purpose was to study the concentration of soluble tumor necrosis factor receptor-Ⅰ(sTNFR-Ⅰ) in the serum of patients with acute tuberculosis. Methods: The levels of soluble TNFR-Ⅰ in serum were measured in 11 patients with acute tuberculosis. Concentration of sTNFR-Ⅰ were measured by using enzyme-linked immunological binding assay. Results: In patients with acute tuberculosis, especially severe tuberculosis, serum levels of sTNFR-Ⅰ increased significantly (P<0.01), compared with those of control. After antituberculosis therapy, serum levels of sTNFR-Ⅰin patients with acute tuberculosis decreased by various degrees. Conclusion: Measurements of sTNFR-Ⅰ in serum of patients with acute tuberculosis could be an important index in the judgement of the outcome of the disease.

Objective To investigate the influencing factors on thrombin time (TT) assay to ensure the accuracy of the detection results.Methods Totally 3 out-and in-patients from January to July 2015 with normal results of prothrombin time (PT),activated partial clotting enzyme live time (APTT) and fibrinogen (FIB) were selected,whose detection results were not satisfactory.The specimen underwent re-centrifugation,and then Beckman ACL TOP700 automatic coagulation analyzer was used to detect four coagulation indexes.The detection results were compared with those before re-centrifugation,and the differences between the results were analyzed statically.Results The values of PT,APTT and FIB of the three patients before and after re-centrifugation were (10.8,11.5,9.7 s),(29.5,32.7,25.2 s),(2.49,3.12,2.85 g/L) and (10.9,11.3,10.0 s),(30.4,31.5,25.9 s),(2.31,3.28,2.67 g/L) respectively,and the differences between the results were not significant (with t ranging from 0.627 to 1.719 and P＞0.05).The values of TT of the three patients before and after re-centrifugation were (66.51,127.3,89.62 s) and (12.2,15.7,13.8 s) respectively,and there were obvious differences between the values (with t ranging from 51.743 to 79.167 and P＜0.001).Conclusion Insufficient centrifugation has high influences on the detection result of TT except other coagulation indexes,and re-centrifugation is necessary for the accuracy of TT value to eliminate misdiagnosis.
