Objective To compare the clinical therapeutic effects of continuous veno-venous hemofiltration (CVVH) and continuous veno-venous hemodiafiltration (CVVHDF) for treatment of patients with multiple organ dysfunction syndrome (MODS).Methods A prospective observation was conducted, seventy patients with MODS admitted to the Department of Critical Care Medicine of the Affiliated Hospital of Zunyi Medical College from September 2013 to December 2016 were enrolled, and they were divided into a CVVH group and a CVVHDF group according to different treatment, 35 cases in each group. In the CVVH group, the ultrafiltration fluid flow rate was set at 1800 mL/h, while in the CVVHDF group, the flow rate was set at 2000 mL/h for both substitution fluid and dialysate, and the blood flow of the two groups was 150-180 mL/min. The changes of creatinine (SCr), urea nitrogen (BUN), pH value, HCO3-, helper T cell (Th1, Th2) and Th1/Th2 ratio were compared between the two groups before and after treatment for 24, 48 and 72 hours.Results With the extension of time, SCr, BUN were reduced in both groups after treatment compared to those before treatment, 72 hoursafter treatment they reached the lowest value, and the degree of change in CVVHDF group was more significant than that in CVVH group [SCr (μmol/L): 150.62±32.09 vs. 180.41±30.52, BUN (mmol/L): 7.31±2.19 vs. 9.06±2.36. allP < 0.05], after treatment; the pH value, HCO3- level in the two groups had a tendency at first elevated and then lowered, 48 hours after treatment they reached the peak values, compared with those before treatment, the differences were statistically significant [CVVH group: the pH value 7.42±0.08 vs. 7.25±0.10, HCO3- (mmol/L) was 22.49±5.11 vs. 15.65±4.16; CVVHDF group: pH value 7.41±0.04 vs. 7.24±0.11, HCO3- (mmol/L) 23.24±4.78 vs. 15.65±4.16, allP < 0.05], 72 hours after treatment, they began reduced (CVVH group: pH value, HCO3- were 7.39±0.09, 22.35±4.91 respectively, CVVHDF group: pH value, HCO3- were 7.38±0.06, 23.13±4.61 respectively), but they were still significantly higher than those before treatment, and at each time point compared between the two groups, no statistical significant difference was seen (allP > 0.05). With the extension of therapeutic time, Th1, Th1/Th2 in two groups were gradually elevated after treatment, and 72 hours after treatment they reached the peak values; Th2 showed a trend of gradual decrease and after 72 hours of treatment it reached the lowest value, and the changes in CVVHDF group were more significant than those in CVVH group [Th1 (×10-2): 1.51±0.12 vs. 1.21±0.11, Th2 (×10-2): 1.64±0.65 vs. 1.70±0.18, Th1/Th2: 0.91±0.14 vs. 0.71±0.15, allP < 0.05].Conclusion Both CVVH and CVVHDF can effectively remove inflammatory mediators and metabolic products, adjust the balance of acid and base, regulate immune system in the body of patients with MODS, and the CVVHDF is more effective than CVVH.

OBJECTIVETo evaluate the clinical efficacy of treating myelodysplastic syndrome (MDS) by hematopoietic stem cell transplantation (HSCT) combined with Chinese medical syndrome typing.

METHODSFrom July 2009 to July 2013, 6 MDS patients were treated with allo-HSCT combined with Chinese medical syndrome typing from HLA-identical sibling donors at Department of Hematology, Zhejiang Provincial Hospital of Chinese Medicine. Patients were classified as refractory anemia (RA, 2 cases), refractory anemia with ringed sideroblast (RARS, 1 case), refractory cytopenia with multilineage dysplasia (RCMD, 2 cases), and RA with excess blasts-I (RAEB-I , 1 case). Modified BuCy conditioning regimen was used in all 6 cases. Two patients received bone marrow transplantation (BMT), 1 patient received peripheral blood stem cell transplantation (PBSCT), and 3 patients received BMT + PBSCT. In order to prevent the occurrence of graft-versus-host disease (GVHD), all patients were treated with cyclosporine + methotrexate + mycophenolate mofetil. Different Chinese medical treatment methods (by syndrome typing) were given to patients according to different criticality of international prognostic scoring system (IPSS, 5 at moderate risk and 1 at high risk).

RESULTSAll 6 patients successfully reconstructed their hematopoietic system. The time from transplantation to ANC ≥ 0.5 x 10(9)/L and platelet (PLT) ≥ 20 x10(9)/L were 13 (9-15) days and 11 (9-22) days respectively. Main complications were GVHD. Acute GVHD (aGVHD) occurred in 4 cases, 3 cases of grade I and 1 case of grade II, and local chronic GVHD (cGVHD) occurred in 1 patient. All cases survived with median follow-up of 18 (11-58) months. The overall survival (OS) and disease-free survival (DFS) rate were 100%.

CONCLUSIONSHSCT combined with Chinese medical syndrome typing could improve clinical symptoms, reduce transplant as- sociated complications. So it was an effective treatment choice for MDS.

Objective To evaluate the rehabilitating effect of hyperbaric oxygen on visual pathway lesions with blood oxygen level dependent functional magnetic resonance imaging (BOLD-fMRI) and diffusion tensor imaging (DTI). Methods Sixteen patients with visual pathway lesions (the study group) and twelve healthy volunteers (the control group) were assessed using BOLD-fMRI and DTI. After hyperbaric oxygen therapy, the patients in the study group were again assessed using BOLD-fMRI and DTI. The activated regions of the BOLD-fMRI scan and the fractional anisotropy (FA) value determined from the DTI were calculated. Results Before hyperbaric oxygen treatment, there were significant differences between control and study groups in their BOLD-fMRI activated regions and the FA values of their radiation optics (P≤0.01). After hyperbaric oxygen treatment, there were no significant differences. Conclusion Combining BOLD-fMRI with DT1 could be used to evaluate the rehabilitation effect of hy-perbaric oxygen treatment in patients with visual pathway lesions.

OBJECTIVEElectrical and structural remodeling are of importance for the occurrence and maintenance of atrial fibrillation. We observed association between atrial connexin protein expression and fibrosis in a canine model of prolonged rapid atrial pacing.

METHODS"J"-type electrodes were placed in the right atrial appendage under the guidance of X-ray in 16 dogs, Animals in model group (n = 8) received fast pacing (400 beats/min) for 10 weeks while animals in control group (n = 8) maintained at sinus rhythm. Limb-lead ECGs were recorded at 2, 4, 6, 8 weeks respectively. Burst stimulation was applied to induce atrial fibrillation in all animals after 10 weeks, animals were sacrificed thereafter and the left atrial tissues were taken for myocardial collagen measurement (Masson staining) and myocardial ultrastructure examination and detection of protein expression of connexin (Cx) 40 and 45 (immune staining). Procollagen type III N-terminal peptide and type IV collagen in serum were also detected by radioimmunoassay.

RESULTSTwo dogs died in model group due to atrial rupture induced cardiac tamponade or lung emboli. Spontaneously atrial fibrillation was not observed in all animals, but two dogs developed atrial flutter and atrial premature beats. Atrial fibrillation was induced by burst stimulation in 4 out of 6 dogs in model group and in none of the dogs in control group. Atrial myocardial collagen volume fraction was significantly increased in model group compared with the control group (P < 0.05). Ultrastructure examination in atrial tissue evidenced disorder, fracture, collagen fiber proliferation, mitochondrial swelling, blurred cristae, and intercalated disc distortion, expansion, part of gap junction disappears in model group. The serum levels of procollagen type III N-terminal peptide and type IV collagen in model group were significantly higher than in the control group (P < 0.05). The protein expression of Cx 40 in atrial myocardium in model group was significantly higher than in control group (P < 0.05), while Cx 45 protein expression was similar between two groups (P > 0.05). The left atrial CVF was positively correlated with Cx 40 (r = 0.671, P < 0.01).

CONCLUSIONIncreased myocardial fibrosis is positively correlated with upregulation of myocardial Cx 40 protein expression in left atrium in rapid atrial paced canine.

Objective To evaluate the acute and delayed killing effect of high intensity focused ultrasound (HIFU) on Echinococcus granulosus(E. granulosus)protoscolices in vitro.Methods E. granulosus protoscolices were treated with different dosage of effective power(0,25,50,100,200,250 W)and time(5,10,20,30,40,50,60 s)of HIFU in vitro to obtain the dosage-effect curves.Then the survival pmtoscolices were incubated,and the mortality of each group was counted daily.The protoscolicidal effects were investigated by trypan blue exclusion assay.Results Compared with the untreated group,the Vitality of E.granulosus protoscolices significantly decreased immediately after treated by HIFU of different dosage(F=5201.59 vs 1865.65,P＜0.05),there were the interaction both different dosage and time(F=214.50,P＜0.05).The protoscolices were broken into pieces by HIFU of 250 W×40 s,whereas the growth of the surviving protoscolices after exposed to HIFU was obvious suppressed.Both the acute killing effect and the delayed inhibitory effect showed a dosage-dependant manner.The inhibitory effect increased along with the increased dosage of HIFU(P＜0.05).The inhibitory effect in 50 W×10 s group was stronger than 25 W×20 s group(P＜0.05).The mortality was increased in parallel with the increase of HIFU dosage.Conclusions HIFU show an effective immediately killing effect,as well as a growth-inhibiting effect on the E.granulosus protoscolices in vitro.

Objective To investigate the effects of functional magnetic resonance imaging (fMRI)with acute ischemic stroke (AIS) patients,and to evaluate the relationship between brain reorganization and motor recovery.Methods Nine AIS patients and 9 healthy volunteers were assessed by fMR1 during passive finger clenching at a pace of 1 Hz.The fMRI results were analyzed using SPM2 software.Lateral indices (LIs) and activated regions were calculated,and the relationship between LI and muscle strength was examined.Results In the control group,activation was observed in the contralateral sensorimotor cortex (SMC) and the bilateral supplementary area (SMA) during the passive movement.In the AIS group,similar results were recorded dur- ing unaffected hand movement,but the ipsilateral activation areas were greater than those on the eontralateral side during movement of the affected hand.LI results confirmed that movement of the affected hand mainly elici- ted activation in the ipsilateral hemisphere.Conclusion The different fMRI manifestations of patients and nor- mal subjects reflect brain compensation,and fMRI is valuable for studying the correlation between motor function and brain reorganization.

Background/Aims: Single-balloon enteroscopy (SBE) has been widely used in diagnosing small bowel disease. We conducted this study to systematically appraise its technical and clinical performance. Methods: Studies on SBE published by September 2018 were systematically searched. Technical and clinical performance data were collected and analyzed with descriptive or meta-analysis methods. Results: In total, 54 articles incorporating 4,592 patients (6,036 procedures) were included. Regarding technical parameters, the pooled insertion depths (IDs) for anterograde and retrograde SBE were 209.2 cm and 98.1 cm, respectively. The pooled retrograde ID in Asian countries was significantly greater than that in Western countries (129.0 cm vs 81.1 cm, p<0.001). The pooled anterograde and retrograde procedure times were 57.6 minutes and 65.1 minutes, respectively.The total enteroscopy rate was 21.9%, with no significant difference between Asian and Western countries. Clinically, the pooled diagnostic yield of SBE was 62.3%. Obscure gastrointestinal bleeding (OGIB) was the most common indication (50.0%), with a diagnostic yield of 59.5%. Vascular lesions were the most common findings in Western OGIB patients (76.9%) but not in Asian ones (31.0%). The rates of severe and mild adverse events were 0.5% and 2.5%, respectively. Conclusions SBE is technically efficient and is clinically effective and safe, but total enteroscopy is relatively difficult to achieve with this technique. Etiologies of OGIB in Asian countries differ from those in Western countries.
