Sixty barrows (Duroc × Labdrace × Yorkshine) were randomly assigned to two groups by weight of 33 kg,each of which was replicated three times with ten pigs. Half of the pigs were fed with diets containing 10 mg/kg lead and 0.5% particulate montmorillonite,the other half pigs were fed only with diets supplemented 10 mg/kg lead as control groups for 100 days.The results showed that the addition of particulate montmorillonite to the diet significantly decreased lead concentration in tissues such as blood,brain,liver,bone,kidney and hair and enhanced the erythropoiesis as measured by increasing numbers of RBC,hemoglobin and hematocrit values ,and elevated ALA-D activity in liver. The damage of lead to the liver was evident in the increases in hepatic concentration of malondialdehyde (+ 17.08% );decreases in the antioxidant enzymes catalase(-85.73 % ),superoxide dismutase ( - 52.17% ) and glutathione peroxidase ( - 47.56% ). Concomitant use of particulate montmorillonite in the diets completely ameliorated the lead-induced oxidative damage. It indicated that particulate montmorillonite is possessed of the potential therapeutic activity against lead poison.

Objective To investigate the expression of Dickkopf-3 (Dkk-3) in esophageal cancer and normal esophageal tissue and the relationship between Dkk-3 expression and the biological behaveior of esophageal cancer. Methods Immunohistochemical method of S-P was used to examine Dkk-3 expression in 69 cases of esophageal squamous cell carcinoma and 5 cases of normal esophageal tissue with non-tumor tissue microarray and the results were analyzed and correlated with their clinical and pathological features. Results Positive Dkk-3 expression was observed in 65.7% (44/67) of the esophageal squamous cell carcinoma cases, but only one of the five cases with normal esophageal tissue showed positive microvascular expression of Dkk-3. In cases with positive expression of Dkk-3 significant differences were found in fiber membrane infiltration, depth of invasion, lymph node metastasis and TNM staging (P < 0. 05), while no significant differences were found in the age, gender and pathological grading (P > 0. 05). Conclusions The upregnlation of Dkk-3 expression in esophageal squamous cell carcinoma may contribute to tumor invasion and metastasis.

OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.
METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.
RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.
CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.

Objective:To explore the application value of modified technique of ureter implantation in murine renal transplantation.Methods:Thirty left donor kidneys from BALB/c mice was transplanted into syngeneic mice. Cuff technique was applied for anastomosing kidney artery and vein. The procedure of ureter-bladder anastomoses shifted from implication-fixation-embedding to fixation-implication-embedding. Operative duration, recipient survival rate and complications were recorded.Results:Time for separating vessels, perfusion and excision of donor graft was (25±3) min, (10±6) s for warm ischemia and (25±5) min for cold ischemia. Time for separating recipient vessels was (12±5) min, (7±1) min for arterial anastomosis, (7±1) min for venous anastomosis, (13±2) min for ureter-bladder anastomosis, (5±1) min for right kidney excision and (5±1) min for abdominal closure. Operative duration was(77±3)min. Twenty-six recipients survived over 3 months. The successful operative rate was 86.7%.Conclusions:With a shorter learning curve, modified technique of ureter implantation is easier and faster so as to reduce the postoperative incidence of urinary tract complications during murine renal transplantation.

OBJECTIVETo study the structural integrity and continuity of the bilateral uncinate fasciculus (UF) in patients with temporal lobe epilepsy (TLE) using magnetic resonance diffusion tensor imaging (DTI) and evaluate the impact of structural damage of the UF on the executive function of the patients.
METHODSThirty patients with TLE (14 left, 16 right) and 15 healthy control subjects underwent DTI scanning between January, 2007 and July, 2011, and the left and right UF were analyzed for fractional anisotropy (FA) and fiber mean length.
RESULTSIn the control subjects, the average FA was significantly higher in the left than in the right UF (P<0.01). In patients with left TLE, the average FA of the left UF was significantly lower than that of the control subjects (P<0.01), but the FA of the right UF was comparable with that of the control group (P>0.05). In patients with right TLE, the average FA of the left and right UF was significantly lower than that of the control group (P<0.05 and P<0.01). In patients with unilateral TLE, the FA of their bilateral UF was similar. No significant difference was found in the mean length of UF fiber between these 3 groups.
CONCLUSIONSFA is normally higher in the left UF than in the right UF, but inpatients with TLE, the left FA tends to have a lowered UF regardless of which hemisphere is involved, suggesting an early pathology in the microstructure of the left UF. This finding may help in the investigation of possible reasons for executive function damage in TLE patients.

Objective:
To evaluate the efficacy and safety of nifekalan (NIF) on cardioversion in atrial fibrillation (AF) patients post radiofrequency ablation, and investigate the relevant factors related to the cardioversion efficacy of NIF.
Methods:
We screened patients with sustained AF rhythm after radiofrequency ablation between November 2016 and July 2018. Participants were treated with intravenous NIF 0.4 mg/kg within 5-10 minutes after ablation. We observed the adverse reaction, and monitored the rhythm, heart rate, QT interval and QTc interval before the medication and at 5, 10, 20, 120 min after the medication. According to the drug outcome of NIF, patients were divided into conversion group and non-conversion group, related factors affecting conversion efficacy were evaluated using logistic regression analysis.
Results:
(1)A total of 116 patients were enrolled in the study (63 males and 53 females, mean age was (64±18) years). Among them, 72 patients were converted to sinus rhythm, and the overall successful rate was 62.1%. There were 84 patients with persistent AF, of which 50 cases (59.2%) were restored to sinus rhythm. There were 32 patients with paroxysmal AF, 22 cases (68.8%) of them were restored to sinus rhythm. The conversion time was 1.5 to 12 (6.8±3.4)min. (2) In 116 patients, the QT interval and QTc interval were significantly longer after medication than before the drug administration (

Methods We screened patients with sustained AF rhythm after radiofrequency ablation between November 2016 and July 2018. Participants were treated with intravenous NIF 0.4 mg/kg within 5-10 minutes after ablation. We observed the adverse reaction, and monitored the rhythm, heart rate, QT interval and QTc interval before the medication and at 5, 10, 20, 120 min after the medication. According to the drug outcome of NIF, patients were divided into conversion group and non?conversion group, related factors affecting conversion efficacy were evaluated using logistic regression analysis. Results (1)A total of 116 patients were enrolled in the study (63 males and 53 females, mean age was (64±18) years). Among them, 72 patients were converted to sinus rhythm, and the overall successful rate was 62.1%. There were 84 patients with persistent AF, of which 50 cases (59.2%) were restored to sinus rhythm. There were 32 patients with paroxysmal AF, 22 cases (68.8%) of them were restored to sinus rhythm. The conversion time was 1.5 to 12 (6.8±3.4)min. (2) In 116 patients, the QT interval and QTc interval were significantly longer after medication than before the drug administration (P<0.01), and peaked at about 10th min, and restored to the level before drug administration at about 120th min. (3) There were 8 cases of bradycardia (6.9%), 3 cases of frequent and short ventricular tachycardia (2.6%). (4) The duration of atrial fibrillation was shorter and left atrial diameter was smaller in the cardioversion group than in the non?cardioversion group (both P<0.05). There were no significant differences in gender, disease history, atrial fibrillation type and structural heart disease between the two groups (P>0.05). (5) Multifactorial logistic regression analysis showed that the duration of atrial fibrillation ( OR=0.980, 95%CI 0.966-0.994, P=0.004) and the left atrial diameter ( OR=0.888, 95%CI 0.814-0.967, P=0.007) were the factors that influence the cardioversion efficacy of NIF on atrial fibrillation post ablation. Conclusions The total effective rate of NIF was 62.1% in patients witrh sustained AF post radiofrequency ablation, was 68.8% in patients with paroxysmal AF. Besides, NIF has the advantage of short conversion time and few adverse reactions. Left atrium diameter and AF duration were relevant factors that influence the efficacy of NIF of cardioversion in patients with sustained AF after radiofrequency ablation.
