Objective To evaluate the effect of live combined bifidobacterium, lactobacillus and enterococcus capsules for colitis in rats induced by trinitrobenzenesulfonic acid (TNBS), so as to explore a new therapy for inflammatory bowel diseases (IBD). Methods 50 female adult Sprague-Dawley rats were randomly divided into 5 groups i. e. normal control group(G1) ,untreated TNBS-induced colitis(G2) ,TNBS-induced colitis treated with live combined bifidobacterium, lactobacillus and enterococcus (G3), TNBS-induced colitis treated with olsalazine (G4) and TNBS-induced colitis treated with both live combined bifidobacterium, lactobacillus and enterococcus and olsalazine at the same dose and duration (G5). Each group received its respective treatment. Serum levels of C-reactive protein (CRP), TNFα and IL-10 were measured with ELISA, colonic myeloperoxidase (MPO) activity was determined with spectrophotometric method, histopathologic picture of the colon of each rat was studied with microscope and colonic mucosa damage index(CMDI) was recorded. Results Serum CRP,TNFα,IL-10,CMDI and colonic MPO in G1 were significantly lower than those in G2 (P < 0. 001) with normal colonic architecture. G2 exhibited the most severe colonic inflammation and the highest levels of CRP,TNFα, IL-10, CMDI and colonic MPO with stastical significance. Treatment groups G3, G4 and G5 showed more obvious colonic inflammatory remission and lower levels of serum CRP,TNFα , IL-10 and colonic MPO, G5 being most notable when compared to G2 with stastical significance. In G2, serum levels of CRP, TNFα, IL-10 and colonic MPO activity each correlated positively with CMDI (P < 0. 001). Conclusions Live combined bifidobacterium, lactobacillus and enterococcus can effectively ameliorate colitis in rats induced by TNBS; the underlying mechanism may possibly be associated with the serum levels of cytokines.

Objective:To explore the correlation between hepatitis B virus (HBV) infection and deep infection after spinal internal fixation surgery and analysis of pathogenic bacteria.Methods:One hundred and eighty-four patients who underwent spinal internal fixation with HBV infection in Xiaogan First People′s Hospital of Hubei Province from January 2013 to January 2019 were selected as the HBV infection group, and 184 patients who underwent spinal internal fixation with non-HBV infection were selected as the non-HBV infection group. The incidence of deep infection and the distribution of pathogenic bacteria were compared between 2 groups. The influencing factors of postoperative deep infection and HBV reactivation in patients with HBV infection were analyzed by single factor analysis and multi-factor Logistics regression analysis.Results:The incidence of deep infection after spinal internal fixation surgery in HBV infection group was significantly higher than that in non-HBV infection group: 19.57% (36/184) vs. 9.24% (17/184), and there was statistical difference ( P<0.01). The pathogenic bacteria of deep infection in both groups were mainly acinetobacter bausinensis, klebsiella pneumoniae, staphylococcus aureus, staphylococcus epidermidis. There was no statistically significant difference in the distribution of pathogenic bacteria between 2 groups ( P>0.05). The deep infection incidences in age ≥ 65 years, operation time ≥ 3 h, intraoperative blood loss ≥ 1000 ml, CD 4+/CD 8+<1.4, total lymphocyte count<0.7 × 10 9/L, liver function abnormalities (AST>40 U/L or ALT>50 U/L), HBV-DNA (+) patients with HBV infection were significantly higher: 27.16%(22/81) vs. 13.59%(14/103), 28.77%(21/73) vs. 13.51%(15/111), 31.15%(19/61) vs. 13.82%(17/123), 29.69%(19/64) vs. 14.17%(17/120), 27.78% (20/72) vs. 14.29%(16/112), 7/18 vs. 17.47%(29/166), 30.43%(21/69) vs. 13.04%(15/115), and there were statistical differences ( P<0.05 or <0.01). Multivariate Logistic regression analysis showed that intraoperative blood loss (≥ 1 000 ml), CD 4+/CD 8+(<1.4), total lymphocyte count (<0.7 × 10 9/L), and HBV-DNA (+) were independent risk factors for deep infection after spinal internal fixation in patients with HBV infection ( P<0.01 or <0.05). The HBV reactivation incidence in age ≥ 65 years, operation time ≥ 3 h, intraoperative blood loss ≥ 1 000 ml, liver function abnormalities, HBV-DNA (+), postoperative deep infection patients with HBV infection were significantly increased: 33.33% (27/81) vs. 18.45% (19/103), 34.25% (25/73) vs. 18.92% (21/111), 34.43% (21/61) vs. 20.33% (25/123), 8/18 vs. 22.89% (38/166), 34.78% (24/69) vs. 19.13% (22/115), 41.67% (15/36) vs. 20.95% (31/148), and there were statistical differences ( P<0.05). Multivariate Logistic regression analysis showed that intraoperative blood loss (≥ 1 000 ml), HBV-DNA (+) and postoperative deep infection were independent risk factors for HBV reactivation after spinal internal fixation in patients with HBV infection ( P<0.05 or <0.01). Conclusions:HBV infection significantly increases the incidence of deep infection after spinal internal fixation surgery, and the independent risk factors are intraoperative blood loss (≥1 000 ml), CD 4+/CD 8+ (<1.4), total lymphocyte count (<0.7 × 10 9/L), and HBV-DNA (+). Spinal internal fixation surgery can cause HBV reactivation, and its independent risk factors are intraoperative blood loss (≥ 1 000 ml), HBV-DNA (+) and postoperative deep infection.

Objective To evaluate the safety to perform 23G vitrectomy with scleral incisions at 5.0 mm behind the limbus.Methods This is a prospective uncontrolled case study.The data of 140 consecutive primary 23G vitrectomy patients (145 eyes) were enrolled in this study.There were 56 males (59 eyes) and 84 females (86 eyes),with the mean age of (56.34 ± 9.98) years and axial length of (23.99± 2.57) mm.There were 139 phakic eye and 6 aphakic eyes.All the eyes received 23G pars plana vitrectomy with scleral incisions at 5.0 mm behind the limbus.To measure the normal Chinese adult parameters of anteroposterior axis of the eyeball,lens thickness and scleral distances from the limbus to the plane passing through the lens posterior apex,the head CT scans of 105 patients without eye diseases in our hospital were studied during the same period of time for these vitrectomy surgeries.Pearson correlation analysis was used to analyze the relationship between age,anteroposterior axis of eyeball,lens thickness and scleral distances from the limbus to the plane passing through the lens posterior apex.Results Surgical related complications included retinal tears close to the scleral incision sites (3/145 eyes,2.1％) and lens injury (3/121 eyes,2.5％).No other surgical complications occurred,such as retinal hemorrhage,supra-choroidal expulsive hemorrhage and iatrogenic retinal detachment.Based on CT images,the average scleral distance from limbus to the plane passing through the lens posterior apex,anteroposterior axis of eyeball and lens thickness was (6.72± 0.81),(24.39± 0.97),(4.22 ± 0.47) mm,respectively.The results of Pearson correlation analysis showed that age and lens thickness had statistically significant correlation (r=0.328 9,P=0.000 6).Conclusion Primary 23G pars plana vitrectomy with incisions at 5.0 mm posterior to the limbus is safe.

Objective This study aims to investigate the association of apoB/apoA-1 ratio with insulin resistance (IR) in patients with non-alcoholic fatty liver disease (NAFLD) . Methods A total of 224 patients with NAFLD and 166 healthy subjects were enrolled as NAFLD group and control group. Weight, height and blood pressure were recorded. Serum levels of fasting blood glucose (FPG), insulin (Fins), lipids, glycated hemoglobin (HbA1c) were measured. Homeostasis model assessment-insulin resistance (HOMA-IR) indices were calculated. Results Compared with control group, NAFLD group had higher apoB/apoA-1 ratio (0.76 ± 0.28 vs 0.61 ± 0.26) and HOMA-IR (2.43 ± 1.68 vs 1.86 ± 1.61) . Spearman correlation analysis showed that in NAFLD group, HOMA-IR positively correlated with age, body mass index (BMI), triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), apoB/apoA-1 ratio (r =0.34, P < 0. 05) and HbA1c, and negatively correlated with high-density lipoprotein cholesterol (HDL-c) . Multiple linear regression analysis revealed that apoB/apoA-1 ratio was still associated with HOMA-IR in NAFLD group after adjustment for age and BMI. Conclusion The apoB/apoA-1 ratio is closely associated with IR in patients with NAFLD. ApoB/apoA-1 ratio may play a role in the development of IR in NAFLD.

Background Our previous study demonstrated that the aptamer S58 specifically targeted transforming growth factor-β receptor Ⅱ (TβRⅡ) and inhibited the transdifferentiation of human Tenon capsule fibroblasts (HTFs) mediated by transforming growth factor-β (TGF-β).Chitosan-nanoparticles (CS-NP) are good drug carriers,but the efficacy and safety of CS-NP/aptamer complexes deserve attention.Objective The aim of this study was to synthesize a novel CS-NP/aptamer complex called CS (S58)-NP and investigate its properties and applicability.Methods Human Tenon capsule tissue was obtained from patients during strabismus surgery,and HTFs were cultured and passaged using the explant culture method.The fourth to tenth generations of cells were used in the experiment.Different concentrations of CS-NP were used to prepare the CS(S58)-NP by the ionic cross-linking method with a surface charge rate (N/P) for S58 of 10,20,30 or 40.The particle size and Zeta potential were measured by the Zeta analyzer.The shape and distribution of CS (S58)-NP particles were examined under the scanning electron microscope.The binding of CS-NP with S58 and resistance of CS (S58)-NP to DNase Ⅰ were examined by agarose gel eletrophoresis.The release rate of S58 from CS (S58)-NP in PBS was quantitatively analyzed by a ultraviolet spectrophotometer.The cytotoxicity of CS(S58)-NP to HTFs was evaluated by detecting the production of lactate dehydrogenase (LDH).Results The Zeta analyzer showed that the particle size of CS (S58)-NP was 130-270 nm and its electric potential ranged from + 16 to +28 mV.The CS (S58)-NP particles appeared spherical with an even distribution under the scanning electron microscope.The mean encapsulation efficiency of CS(S58)-NP was 88.9％,89.3％,91.7％ or 90.5％,respectively,when the N/P was 10,20,30 or 40.After being encapsuled by CS-NP,S58 could resist the degradation from DNase I.Its total releasing level in PBS increased with the lapse of time,with a maximum releasing speed at 24 to 36 hours.The total releasing level reached 100％ at 96 hours.With increaseing concentrations of CS(S58)-NP,the relative releasing level of LDH in HTFs suspension gradually elevated with a significant difference among the groups (F =588.018,P =0.000),with the highest released LDH level at 50 nmol/L of CS(S58)-NP (12.853％ ±0.375％).Conclusions CS-NP provides a protective and slow-releasing effect on the S58 aptamer.CS (S58)-NP shows a good biocompatibility with HTFs with a low cytotoxicity at a concentration of ＜50 nmol/L.CS(S58)-NP could be used to inhibit TGF-β induced transdifferentiation of HTFs in the future.

Objective To evaluate the clinical effectiveness of the treatment for the proximal femur malignant bone tumor by conducting intercalary diaphyseal endoprosthetic reconstruction.Methods Form June 2011 to July 2014,7 patients who had proximal femur malignant bone tumor were treated with intercalary diaphyseal endoprosthetic reconstruction.There were 3 males and 4 females,61.8 years old on the average (ranging from 28 to 76 years).The tumors involved:4 case of the limbs primary malignant tumor,1 case of osteosarcoma,1 case of juxtacortical osteosarcoma,1 case of malignant lymphoma with pathological fracture,and 1 case of malignant fibrous histiocytoma with pathological fracture,as well as 3 cases of the Metastatic breast cancer of the proximal femur.All patients were evaluated by plain radiography,CT and MRI before operation.After these 7 patients were examined with MRI and the level of osteotomy was determined,prosthesis fitting is ready.The exposures of all the tumors were via the femur lateralis surgical approach.According to the general principles of tumor surgery,expose the tumor segment and soft tissue tumors.The segment of involved bone was then removed,with a surrounding cuff of normal tissue overlying the tumor.The level of osteotomy was determined as the result of preoperative imaging measurement.The proximal and distal femur intramedullary canals are reamed.The prosthesis is assembled and installed after the cement used.Results The duration of surgery was from 45 min to 120 min (90 min on average).The blood loss was from 200 ml to 800 ml (400 ml on average).All patients were followed-up for 6 months to 2 years (14 months on average).1 case with osteosarcoma died due to pulmonary metastases 18 months after surgery.The remaining 3 cases with the primary malignant bone tumors did not recur or transfer during the follow-up period.1 case with the metastases was comprehensive treated in another hospital,and survival with tumors.The remaining 2 cases with the metastases did not recur or transfer during the follow-up period.Conclusion The clinical results demonstrated that the intercalary diaphyseal endoprosthetic reconstruction was an ideal treatment for the proximal femur malignant bone tumor.
