Objective: To observe the clinical therapeutic effect of medium frequency electro-stimulant for dysphagia in acute cerebral arterial thrombosis. Methods: 80 patients with dysphagia after cerebral arterial thrombosis were randomly divided into therapy group and control group. The clinical medication of two groups was identical. The ice-stimulation was used in control group and medium frequency electric stimulation in therapy group respectively. The amelioration of dysphagia was observed after one month. Results: The cure rate of therapy group was 35% and the total effective rate was 90%. Compared with the control, the difference was significant. Conclusion: Medium frequency electric stimulation is a available, convenient and safe method for therapy the dysphagia in cerebral arterial thrombosis, which can be recommended in clinical.

OBJECTIVE: To explore the pathogenic mechanism of liver-yang hyperactivity type of hypertension and to observe the effects of Pinggan Qianyang Formula (PGQYF), a compound of traditional Chinese herbals for calming the liver and suppressing yang, so as to provide experimental evidence for new marker proteins of drug therapy. METHODS: A rat model of liver-yang hyperactivity was prepared with spontaneous hypertensive rats (SHRs) by administration of Aconiti Praeparatae Decoction. Adrenal proteins were separated by 2D gel electrophoresis (2-DE). The differentially expressed proteins were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and database analysis. RESULTS: The rat model of liver-yang hyperactivity was successfully reproduced, and the PGQYF could decrease the grades of irritability, conjunctival congestion and systolic blood pressure of the rats (P<0.05, P<0.01). After analysis, twelve obviously differentially expressed proteins were found, eight of which were identified. The expression levels of isocitrate dehydrogenase and steroidogenic acute regulatory protein in the untreated group were up-regulated as compared with those in the normal control group, and down-regulated in the treatment group. The expression levels of ferritin light chain, elongation factor Tu, Rho GDP disassociation inhibitor 1, flavin reductase and basic transcription factor 3 in the untreated group were down-regulated as compared with those in the normal control group, and up-regulated in the treatment group. CONCLUSION: Differentially expressed adrenal proteins in SHRs with live-yang hyperactivity are successfully identified. This approach may lay a foundation for the further investigation of pathogenic mechanisms in hypertension with liver-yang hyperactivity and the mechanisms of PGQYF treatment.

Objective To compare the axial length (AL) measured by Lenstar and contact A-Scan in the patients with idiopathic macular hole and study the correlation between the difference of the two measurements and the foveal thickness measured by optical coherence tomography (OCT).Methods Twenty-seven eyes of 26 idiopathic macular hole patients (IMH group) and 27 eyes of 25 patients with mild cataract (control group) were enrolled in this study.Foveal thickness was measured with 3D OCT.The AL was measured by Lenstar and contact A-Scan,and the consistency of the two measurements was determined by Bland Altman analysis.The correlation between the difference of the two measurements and foveal thickness was analyzed by Pearson correlation analysis.Results Mean foveal thickness of IMH and control eyes were (372.85±60.02) μm and (243.44±22.50) μm,respectively.The difference between the foveal thickness of the two groups was highly significant (t=-10.490,P＜0.001).In the IMH group,the AL measured by Lenstar and contact A-Scan were (23.20± 1.12) mm and (23.18± 1.13) mm,respectively,the difference between the two measurements was not statistically significant (t =-0.549,P =0.588),whereas in the control group,the AL was (23.41 ± 0.72) mm by Lenstar and (23.33 ± 0.74) mm by contact A-Scan,the two measurements were significantly different (t=-4.832,P＜0.001).However,no correlation was found by Pearson correlation analysis between the difference of the two measurements and the foveal thickness in either IMH or control group (r=0.181,-0.141; P＞0.05).Conclusions Although there is no difference of axial length measurements using Lenstar and contact A-Scan in IMH eyes,in clinical measurements the results of two instruments should be taken into comprehensive consideration.

OBJECTIVE:To observe the effects of Gegenqinlian colon positioning tablet(GGQLJC)on colon tissue PPAR-γ, NF-κB p65 protein expressions of model rabbits with damp-heat type ulcerative colitis(UC). METHODS:56 rabbits were random-ly divided into normal group(normal saline),model group(normal saline),sulfasalazine tablet(SASP)group(positive control, 0.300 g/kg),Gegenqinlian tablet (GGQL) group (0.225 g/kg) and GGQLJC high-dose,medium-dose,low-dose groups (1.036, 0.518,0.259 g/kg),8 in each group. Except for normal group,rabbits in other groups were cultured for damp-heat-type UC mod-el,intragastrically administrated in the second day of last administration,once a day,for 14 d. Disease activity index(DAI),co-lonic mucosal damage index (CMDI),histological damage (TDI) were scored;colon,spleen and thymus indexes were deter-mined;PPAR-γ,NF-κB p65 protein expressions in colon tissue were detected. RESULTS:Compared with normal group,DAI, CMDI,TDI scores and spleen index,colon index,NF-κB p65 protein level in colon tissue in model group were significantly in-creased(P<0.01);thymus index,PPAR-γprotein level in colon tissue were significantly reduced(P<0.01). Compared with mod-el group,above-mentioned indexes in each administration group were significantly improved (P<0.05 or P<0.01). Compared with GGQL group,DAI and TDI scores,spleen index,colon index,NF-κB p65 protein level in colon tissue in SASP group, GGQLJC high-dose,medium-dose groups were significantly decreased (P<0.05);PPAR-γ protein level in colon tissue in SASP group,GGQLJC high-dose,medium-dose groups were significantly increased (P<0.05 or P<0.01). CONCLUSIONS:GGQLJC has certain improvement effects on model rabbits with damp-heat type UC,which is superior to GGQL. The mechanism may be re-lated to increasing PPAR-γprotein level and decreasing NF-κB p65 protein level in colon tissue.

Objective To examine the expression of tight junction protein claudin-5 in blood-spinal cord barrier (BSCB) after spinal cord injury about rat. Methods One hundred-twenty adult male SD rats were randomly divided into blank group (60) and injured group (60). The animal model of spinal cord injury was established using modified Allen method. The expression of claudin-5 in BSCB was examined at 6 h, 12 h, 1 d, 3 d, 5 d and 7 d (five rats per time point). Western blot and RT_PCR were used to detect protein and mRNA expression levels of claudin-5, respectively. Results The success rate of spinal cord injury molding was 81.7%. In injured group, EB content increased gradually over time, reached the peak at the third day(0.9435 ± 0.0813)μg/g and then reduced gradually (P<0.05), EB content was signifi-cantly higher in injured group than in blank group. Claudin-5 mRNA expression in injured group reduced gradually over time and reached the lowest point at the third day(2.871 ± 0.527)and then increased gradually(P<0.05). Claudin-5 mRNA expression was significantly lower in injured group than in blank group(P<0.05). Claudin-5 protein expression in injured group reduced gradually over time, reached the lowest at the third day(0.072 ±0.008)and then increased gradually (P<0.05). Claudin- 5 protein expression was significantly lower in injured group than in blank group(P<0.05). Con-clusions The alteration of claudin-5 expression after SCI may lead to the permeability of BSCB, which may in turn con-tribute to the secondary spinal cord injury.

A series of valproic acid salicylanilide esters were designed and synthesized based on the principle of prodrug. The structures of the target compounds were confirmed by MS, 1H NMR and 13C NMR. Anti-tumor activities of these compounds against K562, A549, A431 cells in vitro were investigated by MTT assay and SRB assay. The results indicated that the compounds 6h-6j were found to have stronger cell growth inhibitory action than gefitinib, and comparable to niclosamide, which are worth to be intensively studied further.
