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 analyze the characteristics of iatrogenic urerteral injury and summarize the experiences in prevention,diagnosis and treatment of iatrogenic urerteral injury. MethodsA review was made on the injurycauses,the injury locations,the treatment time,the methods of surgical procedures and the results of treatment in 17 patients with iatrogenic ureteral injury treated surgically from 1997 to 2003. Results Of 17 cases of iatrogenic ureteral injuries,gynecological,general surgical and urological procedures resulted in ureteral injuries in 12 cases (71%),four (24%) and one (6%),respectively. Of all the injuries,65% (11/17) appeared in the lower part of the ureter,18% (3/17) in the middle part of the ureter and 18% (3/17) in the upper part of the ureter. The main injury causes were ligation,partial ligation,complete transection and perforation,accounting for 29% (5/17),41% (7/17),24% (4/17) and 6% (1/17),respectively. Four cases were found during operation,nine at days 2-11 after operation and four were treated 3-6 months after injury. Treatment methods included end-to-end ureteral anastomosis in seven cases,ureteroneocystostomy in three,ureteral lithotomy in one,pure ureteral lysis in three and post-lysis double-J tube insertion in three. All patients were cured. The follow-up ranging from six months to three years showed no patients suffering from urinary tract infection,hydronephrosis or atrophy. Conclusions The location and type of injury determine the type of surgical repair. A thorough knowledge of pelvic anatomy and mastering the basic steps of diagnosis and treatment are critical for prevention and management of the iatrogenic urerteral injury.

Objective To explore the effects of ureteral stent on renal pelvic pressure and other urodynamic parameters. Methods Forty-one patients, 28 males and 13 females, with unilateral renal calculi and/or ureteral calculi were recruited in this study. The mean patient age was 47 years old (ranging from 20 to 72 years old). All cases were placed a 4.7 F ureteral stent and 16 F nephrostomy tube after minimal invasive pereutaneona nephrolithotomy (MPCNL). There was no hydronephrosis and residual crushed stone in the ureter after MPCNL in all cases. Renal pelvic pressure, intra-abdo minal pressure, detrusor pressure, bladder pressure changes during the filling and voiding phases with intravesical perfusion flow rate of 40 ml/min were recorded and analyzed. Results At the baseline, IPP0, IAP0, DP0 and BP0 were (33.1±17.0)cm H2O, (27.5±7.0)cm H2O, (3.3±2.9)cm H2O and (30. 9±7.2)cm H2O, respectively; At the maximum cystometric capacity during the filling phase, IPPvol, IAPvol Dpvol and Bpvol were (39.4±67. 3)cm H2O, (31.1±7.3)cm H2O, (10.7±6. 6) cm H2O and (41.6±10.3)cm H2O, respectively; At the maximum bladder pressure during the voiding phase, IPPmax, IAPmax Dpmax and Bpmax were (65.7±17.0)cm H2O, (33.7±9. 7)cm H2O, (41.9±7.8)cm H2O and (75.0±12. 8)cm H2O, respectively;There were statistical significance comparing between any of IPP0, IPPvol and IPPmax(P<0. 01). 27% (11/41)patients were with the pain in kidney area at voiding IPPmax (87.1±14.6) cm H2O, which was significantly higher than IPPmax (57.8±9.5)cm H2O of asyrnptomatic group (30 patients)(P<0. 01). In all cases, the renal pelvic pressure was higher than 40 cm H2O during the voiding phase. Conclusions Renal pelvic pressure increases during the filling phase after placing the ureteral stent, especially during the voiding phase. As renal function will be damaged by the high renal pelvic pressure, we should decrease the utilization of ureteral stent if possible. It is encouraged to remove the ureteral stent as early as possible.

Objective To investigate the effects of small volume resuscitation on hemodynamics and visceral perfusion in dog model of hemorrhagic shock. Methods Twenty-four dogs were hemorrhaged to hold mean arterial blood pressure at 45-55 nun Hg for 45 minutes, and then eight dogs were resuscitated with 6 ml/kg of hypertonic saline (HS group) solution and the other eight resuscitated with 6 ml/kg of hypertonic saline-hydroxyethyl starch (HSS group) solution. The rest eight dogs were set as control and resuscitated with normal saline (NS). Hemodynamics and gastrointestinal intramucosal pH (pHi) were detected after fluid resuscitation. Results (1) All three kinds of solutions could improve early hemodynamics and visceral perfusion. But 30 minutes after fluid resuscitation, the hemodynamics of dogs in HS group, HSS group and NS group began to decrease, with more obvious decrease HS group and NS group compared with HSS group. (2) pHi of three groups began to decrease 120 minutes after fluid resuscitation, but the level of arterial lactate remained unchanged. Conclusions (1) HS has the similar effect as NS in aspect of resuscitation, and HSS is better than HS and NS.(2) pHi is an ideal marker in monitoring the visceral perfusion and has higher sensitivity than arterial lactate.

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.
