Objective To compare the effect of high volume continuous blood purification (CBP) with routine CBP on multiple organ dysfunction syndrome(MODS).Methods 38 patients with MODS were randomly divided into high volume CBP group( treatment group,18 cases) and routine CBP group (control group,20 cases).And they were respectively detected on mean arterial pressure(MAP),dosage of Dopamine,PaO2/FiO2,APACHE [ score,lactic acid,length of stay and mortality in ICU post-treatment 24h and 48h.Results Compared with control group,MAP and PaO2/FiO2 on treatment group were more higher( P ＜ 0.05 ),while dosage of Dopamine,APACHE Ⅱ score,lactic acid were significantly shorter than these of treatment group( P ＜ 0.05 ),and length of stay and mortality in ICU were significantly lower than those of treatmen group [ ( 8.54 ± 4.15 ) d vs ( 11.82 ± 5.76) d,P ＜ 0.05:22.2％ vs 35.0％,P ＜0.05 ].Conclusion High volume CBP could reduce the mortality in ICU compared with control group routine CBP.

Objective To investigate the clinical, neuroimaging and serum risk factors of cerebral microbleeds (CMBs) in patients with ischemic stroke and find the associations between these risk factors and the location and num?bers of CMBs were also analyzed. Methods One hundred and fifty-three patients with acute ischemic stroke were re?cruited in this study and their data werewas retrospectively analyzed. All of the patients underwent MRI- susceptibility weighted imaging (SWI). The location and numbers of CMBs were recordedexamined. The severity of WMLs was assessed using the Fazekas scale. Logistic regressions were performed to find the predictors of the presence of CMBs. The relation?ships between these risk factors and the location and numbers of CMBs were also analyzed. Results Fifty-nine(38.6%) cases had at least one CMB. The frequency of cortical-subcortical, deep and infratentorial CMBs were 34.0%, 24.8%and 27.5%, respectively. Multivariate logistic regression showed that male sex, hypertension and moderate-to-severe deep white matter hyperintensities (DWMH) were independent risk factors of the presence of CMBs. Adjusted with age and sex, partial correlation showed that hypertension only correlated with the numbers of deep CMBs significantly (r=0.174, P=0.032). Moderate-to-severe DWMH significantly correlated with the numbers of cortical-subcortical and deep CMBs (r=0.285, P<0.001 and r=0.258, P=0.001, respectively). Conclusion Male sex, hypertension and moderate-to-severe DWMH were are independent risk factors of CMBs in patients with ischemic stroke. Hypertension correlates with Deep deep CMBs, while Moderatemoderate-to-severe DWMH correlates with cortical-subcortical and deep CMBs.

OBJECTIVEEnvironmental estrogens at an elevated concentration are known to produce adverse effects on human and animal life. However, the majority of researches have been focused on industrial discharges, while the impact of livestock wastes as a source of endocrine disrupters in aquatic environments has been rarely elucidated. In order to investigate the contribution of environmental estrogens from livestock, the estrogenic activity in water samples from a farm wastewater treatment plant was analyzed by a recombinant yeast screening method.

METHODSThe extracts prepared from 15 selected water samples from the farm wastewater treatment plant, among which 6 samples were from pre-treatment section (influents) and 9 from post-treatment section (effluents), were analyzed for estrogenic activity by cellar bioassay. Yeast cells transfected with the expression plasmid of human estrogen receptor and the Lac Z reporter plasmid encoding beta-galactossidase, were used to measure the estrogen-like compounds in the farm wastewater treatment plant.

RESULTSThe wastewater samples from influents showed a higher estrogenic potency than the effluent samples showing a low induction of beta-galactossidase relative to solvent control condition. By comparison with a standard curve for 17 beta-estradiol (E2), estrogenic potency in water samples from the influents was calculated as E2-equivalent and ranged from 0.1 to 150 pM E2-equivalent. The estrogenic potency in water samples from the effluents was significantly lower than that in the influents, and 7 water samples had less detectable limit in the total of 9 samples.

CONCLUSIONYeast bioassay of estrogenic activity in most of the samples from the farm wastewater after disposal by traditional sewage treatment showed negative results.

Objective: To observe the effects of acupoints, cone numbers and durations of moxibustion with different moxibustion methods on skin surface and inside temperature, and to provide references for the clinical standardization of moxibustion amount. Methods: The 42 big-ear white rabbits were divided into 6 groups according to the random number table method, a 1-cone direct moxibustion group, a 2-cone direct moxibustion group, a 3-cone direct moxibustion group, a 1-cone herbal cake-partitioned moxibustion group, a 2-cone herbal cake-partitioned moxibustion group, and a 3-cone herbal cake-partitioned moxibustion group, with 7 rabbits in each group. Shenque (CV 8), Shenshu (BL 23) and Zusanli (ST 36) were used in each group, but the moxibustion methods, cone numbers and durations of moxibustion were different. Rabbits in each group received moxibustion once every other day for 5 times in total. During the intervention, a thermoelectricity coupled probe and a temperature recorder were used to record the real-time acupoint skin temperature and the temperature at different time points, so as to observe, analyze and process the real-time changes in the temperature difference between the surface and inside of acupoint skin. Results: For herbal cake-partitioned moxibustion, the best temperature for cone changing was (46.38±0.51) ℃ when the highest surface temperature was (49.20±0.52) ℃; the multi-factor comparison of acupoint × cone number × time and acupoint × moxibustion method × time showed that time × acupoint, time × moxibustion method and cone number × acupoint had interactive effects (all P<0.05). Comparing skin temperature differences between different cone numbers at the same acupoint, Shenque (CV 8) on the 1st and the 5th days, Shenshu (BL 23) on the 3rd and the 7th days, Zusanli (ST 36) on the 1st and the 9th days of experiment showed statistically significant differences (all P<0.05). The skin temperature comparison of different moxibustion methods at the same acupoint all had statistical differences (all P<0.05), except for Shenque (CV 8) before moxibustion, Shenshu (BL 23) before moxibustion and on the 5th day; Zusanli (ST 36) only showed statistical differences on the 5th and 7th days (both P<0.05). The skin temperature differences of different acupoints after moxibustion in the 1-cone, 2-cone and 3-cone groups were statistically different (all P<0.05); direct moxibustion and herbal cake-partitioned moxibustion at different acupoints were all statistically different (all P<0.05). Conclusion: Cone changing temperature under the same specifications of herbal cake-partitioned moxibustion was confirmed. Temperature difference between surface and inside of different acupoint skin at the same maximum temperature was significantly different due to the cone numbers and moxibustion methods, which showed the highest at Shenshu (BL 23), the second at Shenque (CV 8), and the lowest at Zusanli (ST 36). The influence of acupoint factor should be considered to determine the quantitative indicators of moxibustion.

Objective To study the role of SIRT 1 in apoptosis of PC 12 neuronal cells induced by lipopolysaccharide (LPS). Methods PC12 cells were cultured with different concentrations of LS (50 μg/mL,500 μg/mL,750 μg/mL,1000 μg/mL and 1250 μg/mL),and some other PC12 cells were routinely cultured as controls. MTT assay was employed to identify the cell survival 24 h after the inducement,and accordingly,the suitable LPS concentration for subsequent experiments was determined based on MTT results. And then, cell apoptosis in the experimental groups under the suitable LPS concentration at different times (1/2,2,18,24,and 48 h) and control group was noted by flow cytometry and Hoechst 33258 staining; Western blotting was used to detect the SIRT1 level in PC12 cells. Results Hoechst 33258 staining indicated that a few apoptotic bodies were noted 1/2 h after inducement,expressing as karyopyknosis and karyorrhexis; apoptotic bodies began to increase 18 h after inducement,reaching their peak level 24 h after inducement; and a decreased trend was observed 48 h after inducement. Flow cytometry indicated that significantly higher apoptosis rate at each time point was noted as compared with that in the control group (P＜0.05); and Hoechst 33258 staining showed the same result. Western blotting revealed that the SIRT1 expression was (1.84±0.04) in the control group,decreasing to (1.17±0.09) 1/2 h after the inducement,and reaching the lowest level (0.62±0.03) 24 h after the inducement; and then, the expression was increased to (0.77±0.02) 48 h after the inducement;significant difference on the expression at each time point was noted as compared with that in the control group (P＜0.05). Conclusion LPS can induce PC12 cell apoptosis and SIRT1 protein expression is inhibited,indicating that SIRT1 may take part in the apoptosis and play a protective role to PC12 cells.

OBJECTIVETo verify the clinical efficacy of acupuncture on motor dysfunction in ischemic stroke of subacute stage.

METHODSThe multi-central randomized controlled trial was adopted. One hundred and twenty-six cases of ischemic stroke of subacute stage were randomized into an acupuncture group (61 cases) and a conventional treatment group (65 cases). The basic treatment of western internal medicine and rehabilitation training were applied to the patients of the two groups. In the acupuncture group, acupuncture was supplemented at the body points located on the extensor of the upper limbs and the flexor of the lower limbs. In combination, scalp acupuncture was applied to NS5, MS6 and MS6 on the affected side. The treatment was given 5 times a week and totally 8 weeks were required. The follow-up observation lasted for 3 months. The scores in Fugl-Meyer scale and NIHSS scale and Barthel index were compared between the two groups before treatment, in 4 and 8 weeks of treatment and the 3-month follow-up observation after treatment separately.

RESULTSIn 4 and 8 weeks of treatment and the follow-up observation, Fugl-Meyer scale score was improved obviously in the patients of the two groups (all P<0. 01). In 8 weeks of treatment and the follow-up observation, Fugl-Meyer scale score in the acupuncture groupwas im proved much apparently as compared with that in the conventional treatment group [68. 0 (43. 0,86. 5) vs 52. 5 (30.3, 77.0), 77.0 (49.5, 89.0) vs 63. 0 (33.0, 84.0), both P<0. 05]. Except that NIHSS scale score was not reduced apparently in 4 weeks of treatment in the conventional treatment group (P>0.05), the results of NIHSS scale at the other time points were all decreased obviously as compared with those before treatment in the patients of the two groups (all P<0. 01). In 8 weeks of treatment and the follow-up observation, the results in the acupuncture group were reduced much apparently as compared with those in the conventional treatment group [5. 0 (3.0,8.0) vs 7. 0 (3.0,13.8), 4. 0 (1.5,7.0) vs 6.0 (2.0,11.7) ,both P<0. 05]. In 8 weeks of treatment and the follow-up observation, Barthel index was improved obviously as compared with that before treatment in the patients of the two groups (all P<0. 05). The improvement in the acupuncture group was much more significant as compared with the conventional treatment group [75. 0 (60. 0,87. 5) vs 65. O (36. 3, 87. 5), P<0. 051.

CONCLUSIONBased on the conventional treatment, Acupuncture achieves the satisfactory clinical efficacy on motor dysfunction in ischemic stroke of subacute stage.

BACKGROUNDThe conventional thoracic endovascular aortic repair (TEVAR) involves groin incisions under general or epidural anesthesia. As technology moves towards less invasive procedures, a total percutaneous approach is desirable. In this study, we describe a Preclosing technique and investigate its safety and efficacy for femoral access sites management, and evaluate its advantages as compared to those of traditional surgical cutdown approaches.

METHODSThe Preclosing technique involves two or multiple 6 F Perclose Proglide devices deployed in the femoral artery before upsizing to a 20-25 F sheath. The sutures were secured to close the arteriotomy at the end of the procedure. The medical records of patients who underwent thoracic endovascular aortic repairs using the Preclosing technique between December 2009 and November 2010 (group A) were compared with those using surgical femoral cutdown from January 2008 to November 2009 (group B). Outcome measures included rates of technical success, early complications, anesthesia method, procedure time, cardiac care unit (CCU) stay, time from procedure to discharge, hospital stay, procedure expense, hospital cost.

RESULTSBetween the two groups, there were no significant differences in baseline characteristics, in the endograft models or profiles. The technical success rate was 100.0% (85/85) in group A vs. 97.4% (147/151) in group B (P < 0.05). There was no access-related mortality in both groups. Compared with group B, the incidence of early complications were fewer in group A, 9.4% (8/85) vs. 22.5% (34/151) (P < 0.01). Local anesthesia with conscious sedation was used more often in group A, 68.2% (58/85) vs. 51.7% (78/151) in group B (P < 0.01). The procedure duration was shorter, (96 ± 33) minutes in group A vs. (127 ± 41) minutes in group B (P < 0.01). The length of the CCU stay, the duration from procedure to discharge, and the hospital stay were both reduced in group A, (117.3 ± 88.3) hours, (7.5 ± 5.3) days and (15.3 ± 6.8) days vs. (132.7 ± 115.5) hours, (10.5 ± 5.0) days and (19.5 ± 7.8) days in group B (P < 0.01). The procedure cost was RMB (109,000 ± 30,000) Yuan in group A vs. RMB (108,000 ± 25,000) Yuan in group B (P = NS). The hospital cost was RMB (130,000 ± 35,000) Yuan in group A vs. RMB (128,000 ± 33,000) Yuan in group B (P = NS).

CONCLUSIONSTotal percutaneous TEAVR with the Preclosing technique is safe and effective with meticulous technique and appropriate patient selection. The Preclosing technique decreases access-related complications, depends less on general anesthesia and the surgeon's cooperation, saves procedure time and shortens the CCU/hospital stay. With these advantages, the use of two percutaneous closure devices increases the hospital cost only slightly.
