Objective: To observe the clinical efficacy of warm needling moxibustion plus spine subtle adjusting manipulation for cervical radiculopathy. Methods: A total of 70 patients with cervical radiculopathy were randomized into an observation group and a control group, with 35 cases in each group. The observation group was treated with warm needling moxibustion plus spine subtle adjusting manipulation, while the control group was treated with warm needling moxibustion alone. The treatments were performed three times a week, and for four weeks in total. The visual analog scale (VAS) was scored before and after treatment. And the clinical efficacy of the two groups was compared after treatment. Results: The total effective rate was 97.1％ in the observation group, versus 88.6％ in the control group. The difference between the two groups was statistically significant (P<0.05). After treatment, the VAS scores in both groups significantly decreased (P<0.01), and the score in the observation group was significantly lower than that in the control group (P<0.05). Conclusion: Warm needling moxibustion plus spine subtle adjusting manipulation has a better effect in the treatment of cervical radiculopathy than warm needling moxibustion alone.

Aim To explore the effects of hypertension on the contractibility of rat basilar artery and its inter-actions with the sodium pump activity.Methods The basilar artery was respectively isolated from Wistar and SHR rats,and the isometric tension of arterial rings was measured by Multi Myograph System-610M.The cont-ractibilities of arterial rings induced by KCl or 5-HT were compared between the basilar arteries of the two groups of rats to analyze the effect of hypertension on the cerebral vascular tension and the activity of sodium pump.Results In SHR rats,the concentration-re-sponse curves of the contraction of isolated basilar ar-tery rings induced by KCl and 5-HT were significantly shifted to right,and the relaxation of vascular tone in-duced by K+which was reintroduced from the external was attenuated compared with those in the WR.These results suggested that hypertension could significantly decrease the activity of the sodium pump and the con-tractile responses of KCl and 5-HT.OUA could con-tract the basilar artery in a concentration-dependent manner,and its concentration-response curve was opti-mally fitted by a two-site binding model:Kd was 1.7 ×10 -8 and 1.6 ×10 -5 mol·L-1,respectively.The results indicated that the two different function sodium pumps existed in the rat basilar artery:one with the high OUA affinity and the other with the low OUA af-finity.If the high and low affinity sodium pumps were inhibited by 5 ×10 -7 and 10 -4 mol · L-1 OUA,re-spectively,the concentration-response curves of KCl and 5-HT would shift to left in SHR rats but not in WR rats.It suggested that OUA could enhance the contrac-tion induced by KCl and 5-HT significantly,and a concentration-dependent effect was observed in the SHR vascular contraction induced by 5-HT (r =0.9393 ,P<0.05 ).When the two concentrations of OUA were applied,there was no significant difference in the shift left of the concentration-response curves in-duced by KCl in the SHR cerebral vessels.However, the marked difference was shown in the shift left in-duced by 5-HT.The results implied that only the high affinity sodium pump was involved in the contractile re-sponse of SHR cerebral vascular to KCl,whereas,the contractile response of SHR cerebral vascular to 5-HT was induced by both high and low affinity sodium pumps.Conclusion Hypertension could lower the contractile response of the basilar artery to vasocon-strictors,and the mechanism might relate to the de-creased sensitivity of the sodium pump induced by hy-pertension or the increased sensibility of the sodium pump to OUA.

Objective To isolate and purify melanin from yeast cells of Penicillium mameffei (PM) and to analyze its physicochemical features.Methods PM yeast cells were cultured in minimal medium containing levodopa (L-dopa) with continuous shaking at 37 ℃.Melanin was isolated from the yeast cells of PM by cell walllysing enzyme,denaturant,concentrated hot acid,and purified by sodium hydroxide and concentrated hydrochloric acid.The physicochemical properties of isolated melanin were assessed on the basis of combined chemical analysis and spectroscopic methods including ultraviolet-visible (UV-vis),Fourier transform infrared (FT-IR) and electronparamagnetic resonance (EPR).Results Similar to synthetic dopa-melanin,the isolated melanin from PM was alkali soluble,acid-resistant,insoluble in water and most organic solvents,precipitated at or below PH 3,and could be bleached by hydrogen peroxide.UV-vis spectrophotometric analysis showed that the PM-derived melanin had a typical absorption peak at 205 nm and the absorbance decreased with the increase of wavelength.FT-IR spectroscopy displayed two absorption peaks at about 3 μm and 6 μm,which was characteristic of classic melanin.EPR spectroscopy revealed that the isolated melanin contained stable free radicals.Conclusion Yeast cells of PM can use exogenous L-dopa to synthesize dopa-melanin.

Objective To investigate the exact protocol eliciting the hippocampal CA1 long-term depression (LTD) of rats in vivo and the effect of amyloid β-protein (Aβ) on the LTD.Method By applying test stimulation to Schaffer collateral in hippocampal CA1 region in rats,recorded the in vivo field excitatory postsynaptic potentials (fEPSPs) ;further,observed the induction of LTD with different low frequency stimulation (LFS) and investigated the effect of Aβ25-35 on the LTD.Results Prolonged LFS (1,5 and 10 Hz) but not paired-pulse stimulus (PPS) effectively elicited the LTD in the hippocampal CA1 region,with significantly decreased amplitude of fEPSPs after LFS ; 1 Hz 900 pulses group induced a stronger LTD,being (63.7 ± 3.8) ％ at 120 min post-LFS,lower (P ＜ 0.05) than (75.1 ± 3.2) ％ in 600 pulses group ; different frequencies (1,5 and 10 Hz) of LFS with same pulses induced similar degree of LTD,the amplitude of fEPSPs were (63.7 ± 3.8) ％,(61.2 ± 3.6) ％ and (59.8 ± 3.9) ％ respectively,without significant differences between any two groups (P ＞ 0.05) ; after applying 12.5 nmol and 25 nmol Aβ25-35,the amplitude of fEPSPs decreased to (63.2 ± 3.8) ％ and (46.8 ± 3.9) ％,respectively,and lower and than that in control ((73.9 ± 3.0) ％,P ＜ 0.05).Conclusion Prolonged LFS effectively induced in vivo hippocampal LTD of rats,which provides an important electrophysiological protocol for the study of synaptic plasticity; Aβ25-35 injection dont affect the baseline synaptic transmission,but dose-dependently enhance the in vivo hippocampal LTD of rats,indicating that Aβ-induced LTD facilitation may be involved the early impairment of learning and memory in Alzheimer's disease.

Objective To investigate the relationship between the expression of p53 protein and Ki-67 antigen in order to detect its clinical characters and the significance of them in them occurrence and development of appendiceal mucinous neoplasms.Methods 42 tissues of appendiceal mucinous neoplasms were selected by pathological diagnosis in the department of pathology of the PLA general hospital from May 1993 to October 2007.The 10 samples of control group were obtained from simple appendicitis after surgery.Applied PV6000 immunohistochemical method,the expressions of p53 protein and Ki-67 antigen were detected.Results The expression of p53 protein in appendiceal mucinous neoplasms was higher than that in appendicitis tissue [31.0 ％ (13/42) vs 0 (0/10),x2 =4.127,P =0.042).The positive rate of p53 protein in appendiceal mucinous adenocarcinoma was higher than that in low-grade appendiceal mucinous neoplasm tissue (40.0 ％ vs 8.3 ％,x2 =4.0218,P =0.044).The positive rate of p53 protein in appendiceal mucinous neoplasms tissue with pseudomyxoma peritonei was higher than that in tissue without PMP (45.5 ％ vs 15.0 ％,x2 =4.5464,P =0.033).The expression of Ki-67 antigen in appendiceal mucinous neoplasms was higher than that in appendicitis tissue (45.2 ％ vs 10.0 ％,x2 =4.2374,P =0.039).Considering the different factors (such as gender,age,pathological type and PMP),Ki-67 antigen expressions were still not significantly different (P ＞ 0.05).In appendiceal mucinous neoplasms,the difference of positive rates of Ki-67 between the p53 positive expression group and the p53 negative group was statistically significant (x2 =7.6299,P =0.0057).Conclusion The expression of p53 protein was correlated with the expression of Ki-67 antigen.It's valuable that both p53 protein and Ki-67 antigen are used to evaluate the biological behavior of appendiceal mucinous neoplasms and predict the malignant degree.
