BACKGROUND: Dihydrolycorine (DL) can inhibit the peripheral release of catecholamine from sympathetic nerve ending and block α, β adrenalinergic receptor. It has multiple pharmacological actions, such as vascular dilation, hypotension, anti-hypoglycemia and anti-ischemia.OBJECTIVE: To investigate the selective effect of DL on basilar artery,thoracic aorta and ventricular papillary muscle of rabbit by means of observing the vasoconstriction induced by noradrenaline bitartrate and KCl.DESIGN: Observation of comparative experiment.SETTING: Pharmacological Department of Yunyang Medical College.MATERIALS: This study was carried out at Pharmacological Department of Yunyang Medical College between March and July 2001, and 46 adult healthy New Zealand rabbits were selected.METHODS: New Zealand rabbits were put to death by intravenous injection of 10 mL air from the vein of aural edge, and soon after death, brain,thoracic aorta and heart were obtained. Basilar artery and thoracic aorta was linked into 4.0-5.0 mm vascular rings; meanwhile, ventricular papillary muscle were separated and connected with tension transducer. Obserdose of noradrenaline bitartrate or KCl: Sub-maximal constriction of thoracic aorta was induced by 0.1 mmol/L noradrenaline bitartrate or W60 mmol/L KCl, and when constriction curve became stable, DL or nimodipine of different dosage was added. Basilar artery was exposed to 0.1 mmol/L noradrenaline bitartrate or 60 mol/L KCl, and rinsing fluid was changed once every 20 minutes and thrice in all when vasocontratcion reached the peak level, then different dosage of DL or nimodipine was added 20 minutes later, and the changes of vasoconstriction curve due to administration of single dose of noradrenaline bitartrate or KCl were obconstriction of ventricular papillary muscular induced by electro-stimulation: Electro-stimulation was used to stimulate the ventricle papillary muscular synchronized constriction with the frequency of once per second,wavelength of 3 ms and threshold voltage of 120%; when constriction curve became stable, DL or nimodipine was administered in a accumulative way.ence of DL or nimodipine on the half-effective concentration of noradrenaline bitartrate or KCl that contributed to the vascular ring constriction of rabbit.RESULTS: Basilar artery, thoracic aorta and ventricular papillary muscle Resting tension of basilar artery was increased by DL but decreased by niof basilar artery and thoracic aorta induced by noradrenaline bitartrate and KCl can be relaxed by DL in a dose dependant manner, and the half-effective concentration was (6.69±3.12)×10-4, (3.41±1.52)×10-3mmol/L for basilar artery, and (1.49±0.59)×10-3, (2.91±0.99)×10-3 mmol/L for thoracic aorta, displaying stronger inhibition on the constriction of basilar artery induced by noradrenaline bitartrate than on the contraction induced by KCl.On the contrary, nimodipine showed stronger depression on KCl-induced constriction than on the constriction induced by noradrenaline bitartrate.ventricle papillary muscular induced by electro-stimulation in a dose-dependant manner, and the half-effective concentration of DL on the contraction of ventricle papillary muscle induced by electro-stimulation was significantly higher than that induced by noradrenaline bitartrate.CONCLUSION: DL displays obvious selective effect on basilar artery of rabbit, the possible existence of constrictive α1 receptor subtype and dilating β receptor on basilar artery might be correlated with the selective function of DL, which benefit, for the improvement of blood supply in the ischemic region.

Objective To explore the roles of interleukin-6 (IL-6) and high sensitive C-reactive protein (hsCRP) in coronary heart disease (CHD). Methods One hundred and fifty patients diagnosed as angina pectoris by coronary angiography were enrolled and randomly divided into unstable angina pectoris group ( UAP group n =78) and stable angina group (SAP group n =72). At the same time,50 cases with normal coronary angiography were selected as control. The plasma level of IL-6 was measured by ELISA, and hsCRP was measured by immunonephelometry. Results The mean plasma levels of IL-6 and hsCRP were significantly higher in UAP group compared with SAP group ( IL-6 ( 36. 98 ± 9. 35 ) pg/L vs. ( 23.19 ± 7. 35 ) pg/L; hsCRP ( 2. 25 ± 0. 73 ) μg/Lvs 1.88 ± 0. 68 ) μg/L; P ＜ 0. 01 respectively), both were significantly higher than those of control group ( IL-6 (16. 93 ± 6. 15 )pg/L and hsCRP (1.28 ± 0.40)μg/L,P ＜0.01 respectively). We also found significantly positive relationship between IL-6 and hsCRP plasma level ( r = 0. 875, P ＜ 0. 05 ). Conclusions Inflammatory response might play an important role in CHD. IL-6 and hsCRP were of high value in prediction of angina pectoris and development of CHD.

Objective To investigate the changes and clinical significance of helper T cells (Th)22,Th17,Th1 and regulatory T cells (Treg) in the peripheral blood before and after antiretroviral treatment (ART) of human immunodeficiency virus (HIV)-1 infected patients.Methods Forty HIV-infected patients were recruited into this study,and 30 healthy subjects were recruited as controls.Peripheral blood of the patients was collected at baseline and after 3 months of ART treatment.The frequencies of Th22,Th17,Th1 and Treg were detected by flow cytometry.Tests for homogeneity of variance and paired t test for comparison was adopted.Spearman rank test was used for correlation analysis.Results The frequencies of peripheral Th22,Th17,Th1 and Treg from HIV-infected patients before treatment were significantly decreased compared to the healthy controls ([0.59± 0.47] ％ vs [1.65 ± 0.56] ％ [t =8.544,P＜0.01],[4.46±1.84]％ vs [6.98±1.86]％[t=5.619,P＜0.01],and [16.75±6.72]％ vs [22.77±6.87]％; [t=5.311,P＜0.01].The frequencies of peripheral Th22 and Th17 after 3 months of treatment were significantly higher than those at baseline ([1.60± 1.10] ％ [t=5.268,P＜0.01] and [6.33±2.64]％ [t=3.663,P＜0.01] and no difference from those of healthy controls (t=1.783 and 1.143,respectively; both P＞0.05).However,the Th1 frequency showed no difference compared to the baseline.The frequency of Treg in the HIV infected patients was significantly increased compared with the healthy controls ([10.76±3.76]％ vs [7.01±1.88]％,t=5.003,P＜0.01).However,it gradually decreased along with the ART treatment ([9.22±2.56]％ after 2 months; [8.57± 2.36]％ after 3 months),which was still higher than that of healthy controls (t=2.984,P=0.004).The ratios of Th22/Treg,Th17/Treg and Th1/Treg of the HIV-infected patients were significantly decreased in comparison with the healthy controls (0.05±0.03 vs 0.25±0.10,t=11.69,P＜0.01; 0.46 ± 0.27 vs 1.07±0.42,t=7.728,P＜0.01; 1.56±0.89 vs 3.37± 1.02,t=7.052,P＜0.01),and those were significantly increased after 3 months of treatment (0.17±0.10[t=6.852,P＜0.01],0.81±0.46[t=4.253,P＜0.01] and 2.31±1.27[t=3.030,P＜0.01]).Correlation analysis showed that the ratio of Th17/Treg of the HIV-infected patients was positively correlated with the peripheral CD4+ T cell count (r=0.312 5,P=0.049 6),and negatively correlated with HIV RNA viral load (r=-0.474 7,P=0.002 0).The ratio of Th1/Treg of the HIV-infected patients was positively correlated with the peripheral CD4+ T cell count (r=0.333 5,P=0.035 5).Conclusions Th22,Th17,Th1 and Treg cells in the peripheral blood of HIV-infected patients are closely related to CD4+ T cell count.ART can partially recover immune imbalance,and help to rebuild immune function of HIV-infected patients.

Objective To explore the methodology of suturing the upper margin of the orbicularis muscle in pretarsal orbicularis myocutaneous flap to the levator aponeurosis,simulating the mechanism of fibers from the levator aponeurosis to the dermis in natural double-eyelid in blepharoplasty.Methods Pretarsal orbicularis myocutaneous flap was harvested.Dissection between the orbital septum and the levator aponeurosis was performed originating from the upper margin of the tarsi until to the levator muscle.The upper margin of the orbicularis muscle in pretarsal orbicularis myocutaneous flap was sutured to the levator aponeurosis.The lower skin margin to the orbital septum to the upper skin margin was sutured interruptedly.Patients with medial epicanthus were performed epicanthoplasty at the same time.Results 136 eyes in 68 patients were performed with double-eyelid blepharoplasty using this method.62 patients were followed-up for 1 month and 53 patients were followed-up for 3 months.They all reported satisfactory aesthetic results.Conclusions Double-eyelid blepharoplasty using this method accords with the physiological mechanism in natural double-eyelid.Postoperative double-eyelid is natural with little tumefaction.This method can avoid double-eyelid fold retraction and multi-fold occurrence.

With DQOL (diabetes quality of life) scale, quality of life was evaluated before and after diabetic education in 136 type 2 diabetic patients.

Objective To discuss the effects of electroacupuncture intervention in different acupoints of rats models with diarrhea type irritable bowel syndrome (D-IBS).Methods The rat models were established with acute and chronic stimulation. The rats were divided into the normal control group, model group, “Taichong” (LR3) + “Zusanli” (ST36) group, and “Tianshu” (ST25) + “Zusanli” (ST36) group. Electroacupuncture was applied to bilateral corresponding acupoints for 20 minutes, every other day for 7 times. The physical signs of each rat were observed. The contents of 5-HT, NE and CGRP in the rats’ plasma were detected by sandwich ELISA. Results Compared with the normal group, the contents of 5-HT and NE in the model group were obviously higher and the content of CGRP decreased (P<0.05). Compared with the model group, the contents of 5-HT and NE in all treatment groups were lower and the content of CGRP increased (P<0.05). There was no difference between the “Taichong” (LR3) + “Zusanli” (ST36) and “Tianshu” (ST25) + “Zusanli” (ST36) groups.Conclusion The mechanism of electroacupuncture may be realized through lowering the contents of 5-HT and NE in the model rats and increasing the content of CGRP to treat D-IBS.
