Objective To study the curative effect and mechanism of moxibustion on heat-sensitive acupoints combined with Erwei Badu Powder in the treatment of elderly herpes zoster (HZ) with type of stagnant heat of liver channel. Methods Sixty-five patients with HZ were randomly divided into treatment group (35 cases) and control group (30 cases). Two groups were orally given Longdan Xiegan Decoction and aciclovir conventionally, the treatment group was given moxibustion additionally on heat-sensitive acupoints combined with Erwei Badu Powder, and the control group was only given external application of Erwei Badu Powder for 10 days. The symptom scores, levels of T lymphocyte subsets and serum interleukin-2 (IL-2) were observed before and after treatment, the curative effect was evaluated, and PHN was followed up. Results The effective rate was 85.71%(30/35) in the treatment group and 66.67%(20/30) in the control group. The curative effect of treatment group surpassed the control group (P<0.05). Incidence of PHN was lower (P<0.01). The levels of CD4, CD4/CD8, and IL-2 increased and the level of CD8 decreased significantly in two groups compared with those before treatment (P<0.05). All indexes were better in the treatment group than those in the control group (P<0.05). Conclusion The curative effect of moxibustion on heat-sensitive acupoints combined with Erwei Badu Powder in treatment of elderly HZ is better than that of Erwei Badu Powder only, particularly in reducing the occurrence of PHN, improving neuralgia and insomnia. The mechanism may be related to increasing levels of CD4, CD4/CD8 and IL-2, and improvement of body’s cell-mediated immunity.

Objective To analyze the feasibility and superiority of off-pump coronary artery bypass grafting(OPCAB) in patients with left main coronary lesions.Methods A retrospective study was carried out to review our experience on 392 cases with left main coronary lesions,who underwent CABG in our hospital.Among the cases,279 patients(71.2%) underwent OPCAB and 113 cases received CCABG.The early postoperative mortality and complications of the two groups were compared.Results The number of bypass grafts was(4.17?0.86) in Group OPCAB and(4.24?0.94) in Group CCABG,showing no significant difference between them(t=-0.710,P=0.478).No significant difference was detected in peri-and post-operative morbidity between the two groups [atrial fibrillation: 31(11.1%) vs 8(7.1%),?2=1.459,P=0.227;perioperative myocardial infarction: 7(2.5%) vs 3(2.7%),?2=0.000,P=1.000;renal inefficiency: 9(3.2%) vs 4(3.5%),?2=0.000,P=1.000;pulmonary complications: 15(5.4%) vs 6(5.3%),?2=0.000,P=1.000].The early postoperative mortality of Group OPCAB was significantly lower than that in Group CCABG[2(0.7%) vs 5(4.4%),?2=4.368,P=0.037].The time of intubation[20(8-48) h vs 51(14-130) h,Z=-2.823,P= 0.005],ICU-stay [51(38-141) h vs 92(42-352) h,Z=-2.618,P=0.009],volume of transfusion [500(200-1200) ml vs 800(400-2100) ml,Z=-2.411,P= 0.016],re-open [5(1.8%) vs 10(8.8%),?2=9.052,P=0.003] and complication of CNS [3(1.1%) vs 9(8.0%),?2=10.647,P=0.001] of Group OPCAB were significantly less than that of Group CCABG.Conclusions It is feasible,safe and effective to perform OPCAB in patients with left main coronary lesions.

Objective The preservation of all subvalvular apparatus for chronic mitral regurgitation has been reported in many studies. In this paper we analyzed the effects of complete chordal preservation for mitral stenosis versus mitral regurgitation on postoperative recovery.Methods Thirty-nine patients undergoing mitral valve replacement(MVR) with preservation of all subvalvular apparatus were divided into two groups, mitral stenosis (MS) group(n=23) and mitral incompetence (MI) group(n=16), according to the preoperative diagnosis. Echocardiography was performed preoperatively and at the time of discharge to determined left ventricular end diastole dimension (LVEDD),ejection fraction(EF) and the hemodynamics of the prosthesis.Results The LVEDD and EF did not change in MS group, declined in MI group postoperatively. No hemodynamic disorder of the prosthesis was detected in either group.Conclusions The valve replacement with preservation of all subvalvular apparatus could be used in both the mitral stenosis and mitral regurgitation.The early-term effects of two groups are similar,and the long-term effects are still to be observed.

Objective:To investigate the preemptive analgesic effect of flurbiprofen on inflammatory cytokine in patients undergoing cerebral operation.Methods:Forty ASA Ⅰ-Ⅱpatients undergoing cerebral surgery were randomly divided into control group(group C,n=20)and flurbiprofen group(group F,n=20).Flurbipmfen of 10 mL was given intravenously 15 min before skin incision.The values of VAS scores were recorded at 2 h,24 h and 48 h after operation.Blood samples were taken for determination of serum levels of TNF-α,IL-6 and IL-10 immediately before induction of anesthesia(T1,baseline),at 2 h of operation (T2),immediately after the end of operation (T3) and 24 h after operation (T4).The parameters of anaesthesia time,hemorrhage volume,urine volume,transfusion volume and the dosage of remifentanil and propofol were recorded during the period of anaesthesia.Results:The VAS score was lower in group F than that in group C at 2 h and 24 h after operation (P＜0.05),but there was no difference at 48 h after operation between the two groups(P＞0.05).The dosages of remifentanil and propofol were lower during anaesthesia in group F than that in group C(P＜0.05).Compared with T1,TNF-α was significantly increased at T2 and T3 in both groups,and the peak value at T2 (P＜0.05).TNF-α was decreased at T2-T4 in group F than that in group C(P＜0.05).Compared with T1,the levels of IL-6 and IL-10 were significantly increased at T2-T4 in both groups,and the peak value at T3(P＜O.05).The value of IL-6 was decreased and the value of IL-10 was increased at T2-T4 in group F than those in group C (P＜0.05).Conclusion:Flurbiprofen was suitable as a preemptive analgesia and could suppress stress reaction of inflammatory in neurosurgery.

Objective To investigate the effects of transfection of chemokine receptor CXCR4 antisense-RNA on the functional expression of VEGF-C mRNA and the invasive ability of colon cell line HT-29 in vitro.Methods PCR primers were designed according to the coding sequence of CXCR4 gene.EcoR Ⅰ and BamH Ⅰ recognition sequences and cutting sites were added to the 5' end of the antisense primer.The purified PCR fragment was retro-inserted into the cloning site of eukaryotic expression vector pcDNA3.1(+).The pcDNA3.1(+)for CXCR4 antisense-RNA was transfected into colon cancer HT-29 cells by liposome transfection.The expression of VEGF-C mRNA was detected by RT-PCR.The expression of CXCR4 protein was determined by Western blot.At the same time,cell growth kinetics was assessed by MTT assay,and in vitro invasive ability was assessed with Boyden chamber.Results CXCR4 antisense-RNA recombinant was successfully constructed.The expression of VEGF-C mRNA in antisense-CXCR4 transfected(HT-29tran)group decreased by 54.2%,while the expression of VEGF-C mRNA in vacant-transfected(HT-29KZ)group only decreased by 9.4% campared with non-transfected(HT-29)group.The difference between the two groups mentioned above was remarkable(P

Objective To explore the effects of ginsenoside Rg3 on the expression of P27 in human erythrol-eukemia cell line K562 and cell proliferation. Methods Human erythroleukemia cell line K562 cells were cultured to exponential phase, then K562 cells were treated with different concentrations of Rg3 (6.25, 12.5, 25, 50, and 100 μg/mL) as Rg3 group, and cells treated without Rg3 (0 μg/mL) were take as control group. After 3 days, K562 cells were observed by Wright-Giemsa staining with microscopy , the proliferation of K562 cells were examined by tetrazolium salt (MTT) assay, and the expression of P27 mRNA were detected by fluorescent quantitative RT-PCR assay. Results MTT assay showed that after treatment with Rg3,the inhibition rate (IR) of proliferation of cells in Rg3 groups were increased gradually , and the differences were significant compared with the control group (P < 0.05). The results of fluorescent quantitative RT-PCR showed the levels of P27 mRNA expression in 25,50 and 100 μg/mL Rg3 groups were significant higher than that of control group (P < 0.05). Conclusion The ginsenoside Rg3 can inhibit the proliferation of K562 cells by inducing the expression of P27.
