Objective To study the methods and skill of vena cava filter placement via the antecubital access. Methods Six patients with DVT (4 males and 2 females, mean age of 62) underwent vena cava filter placement via the antecubital access in Huashan Hospital from Oct. 2004 to May. 2006. The right basilic vein was punctured with the use of micropuncture technique. SNF (Simon nitinol filter, Bard)was inserted through its carrier into the 90-cm-long sheath. The filter was then deployed with a standard fashion in the IVC, 5 cm inferior to the renal vein. Results The filter was once placed successfully in all six patients within average time of 25 min without complications, but with good healing, exclusion of bleeding and no phlebitis. The position of filter was accurate without deviation and no occurrence of pulmonary embolism. Conclusions vena cava filter placement via antecubital access is easy, minimal invasive, no need of lying in bed postoperatively. It is beneficial for DVT patients as an alternative for the contra-indication to femoral venous access.

Objective To investigate the relationship between the serum apolipoprotein B (ApoB)/ ApoA-Ⅰ ratio and intracranial artery stenosis in young patients with ischemic stroke.Methods Patients with ischemic stroke aged from 18 to 45 were enrolled in the study.Brain CT angiography was used to evaluate the degree of intracranial artery stenosis,and the concentrations of serum total cholesterol,triglyceride,highdensity lipoprotein cholesterol,low-density lipoprotein cholesterol,ApoA-Ⅰ,and ApoB were detected.The ratio of ApoB/ApoA-Ⅰ was calculated.The Demographic and clinical characteristics of the intracranial artery stenosis group and the non-intracranial artery stenosis group were compared.Multivariate logistic regression analysis was used to identify the independent risk factors for intracranial artery stenosis in young patients with ischemic stroke.Results A total of 161 young patients with ischemic stroke were enrolled,including 89 in the intracranial artery stenosis group and 72 in the non-intracranial artery stenosis group.The constituent ratios of diabetes mellitus (20.2％ vs.6.9％;x2 =4.641,P =0.032),smoking (47.5％ vs.15.2％;x2 =15.121,P=0.001),hyperlipidermia (56.1％ vs.48.6％;x2 =4.197,P=0.040),as well as the radios in serum high-density lipoprotein cholesterol (1.29 ± 0.30 mmol/L vs.1.65 ± 0.34 mmol/L;t =7.131,P=0.002),ApoA-Ⅰ (1.49 ± 0.65 g/L vs.1.63 ± 0.23 g/L;t =2.751,P =0.001),ApoB (1.49 ± 0.65 g/L vs.1.63±0.23 g/L;t=2.751,P=0.001),and ApoB/ApoA-Ⅰ ratio (1.49±0.65 vs.1.63± 0.23;t =2.751,P=0.001) had significant differences between the two groups.Multivariate logistic regression analysis showed that diabetes (odds ratio [OR] 3.052,95％ confidence interval [CI] 1.186-7.856;P =0.021),smoking (OR 2.997,95％ Cl 1.456-6.172;P =0.003),hyperlipidemia (OR 4.745,95％ CI 2.108-10.668;P =0.001),ApoB (OR 4.861,95％ CI 3.029-7.802;P=0.001),and ApoB/ ApoA-Ⅰ ratio (OR 5.684,95％ CI 2.215-14.584;P=0.002) were the independent risk factors for intracranial artery stenosis in young patients with ischemic stroke,while HDL-C (OR 0.561,95％ CI 0.354-0.888;P=0.014) and ApoA-Ⅰ (OR 0.065,95％ CI 0.010-0.409;P=0.004) were the independent protective factors.After adjustment for hypertension,diabetes,smoking,hyperlipidemia,HDL-C,ApoA-Ⅰ,and ApoB,ApoB/ApoA-Ⅰ ratio was still an independent risk factor for intracranial artery stenosis in young patients with ischemic stroke (each increase of 1 standard deviation,OR 4.255,95％ CI 2.348-7.711;P=0.001).Conclusion ApoB/ApoA-Ⅰ ratio is an independent risk factor for intracranial artery stenosis in young patients with ischemic stroke.

Based on the counting results from nutrition agar in our study, and compared with another two kinds of coliform bacteria detective plates for dinner and drinking sets which were provided by two manufactures and inspected by China National Health Bureau , we accomplished the detectability test of the Huankai coliform bacteria plates. In our study, 3kinds of cell density were adopted: 10cells/mL, 50cells/mL and 100cells/mL . The results shew that the detectability of Huankai plates basically conformed with that of nutrition agar , and was no evident difference from that of another two kinds of plates. The conclusions were that Huankai plates can completely be used in the inspection and test for conform bacteria.

OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).

METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.

RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).

CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

Objective To study the effects of curcumin mediated photodynamic therapy (PDT)on the growth and proliferation in human cervical cancer cell line H8 in vitro and in vivo,and to investigate its antitumor mechanisms.Methods The effects of curcumin mediated PDT on proliferation of human cervical cancer H8 cell by MTT assay was used to screen the optimal parameter.Changes in cell morphology were observed by May-Gr ünwald-Farbstoff Giemsa staining.The apoptosis rate was estimated by flow cytometry.The effect of PDT by curcumin on the expressions of Bcl-2,P53 and survivin in H8 cells was detected by fluorescence real-time reverse transcription-polymerase chain reaction (RT-PCR).Forty BALB/C nude mice underwent subcutaneous injection of H8 cell line so as to establish animal models,and then were randomly divided into four equal groups:control group,irradiation alone group,curcumin alone group,curcumin PDT group.HE staining and pathological examination were performed.Immunohistochemical study was conducted to detect the protein expression of the apoptosis inhibiting genes of Bcl-2.Results The proliferation inhibition of H8 cells was obvious after PDT when curcumin 5μmol/L with irradiation 100 J/cm2,and with dose dependent manner.Typical morphologic features of apoptosis appeared characterizedly by marked chromatin condensation,nuclear pyknosis and fragmentation,and the appearance of apoptotic bodies.The total apoptosis rate was higher in PDT group [(47.21 ± 4.11)％]than in control group(1.71 ±0.16) ％ (P＜0.01).The mRNA expression of Bcl-2,P53 and survivin in H8 cells were suppressed significantly.HE staining showed remarkable subcutaneous necrosis in the PDT group.Immunohistochemistry showed remarkable down-regulation of protein expression of Bcl-2(P＜0.01).Conclusions Curcumin-mediated photodynamic therapy has a significant killing effect on H8 cells in vivo and in vitro.Its antitumor effect might be related to induction of Tumor cell apoptosis and suppression of Bcl-2 mRNA and protein expression.

OBJECTIVETo compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately.

RESULTSThree cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group.

CONCLUSIONThe combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.
