ABSTRACT

Pediatric neurogenic bladder (PNB) is defined as dysfunction of the detrusor and/or urethral sphincter due to myelodysplasia or spinal cord injury, manifesting as impaired urination or defecation, which seriously affects the patients’ quality of life. The main indication for sacral neuromodulation (SNM) is overactive bladder syndrome, which presents as refractory urinary frequency and urgency, urgency incontinence and non-obstructive urinary retention. Age more than 16 years are also recommended for this technique. Previous studies have revealed that SNM could significantly improve the outcome of refractory bladder bowel dysfunction. This paper reviews the advances of the application of SNM in the treatment of pediatric neurogenic bladder so as to provide reference for pediatricians.

ABSTRACT

Objective:To observe and analyze the atypical magnetic resonance imaging (MRI) findings and misdiagnosis reasons of primary central nervous system lymphoma (PCNSL), and to explore the value of conventional MRI signs combined with minimum apparent diffusion coefficient value (ADCmin) and imaging features of magnetic resonance spectroscopy (MRS) in the diagnosis and differentiation of atypical PCNSL.Methods:The clinical and imaging data of 15 patients with atypical PCNSL confirmed by clinical and pathological findings from Lianyungang Second People′s Hospital and the Affiliated Hospital of Xuzhou Medical University from January 2015 to December 2020 was collected. All cases were examined by plain MRI, enhanced and diffusion weighted imaging (DWI), and 3 cases were examined by MRS. The conventional MRI features, DWI signal features and MRS imaging features of 15 cases of atypical PCNSL were observed and analyzed, and the MRI findings of atypical PCNSL and the causes of misdiagnosis were summarized and analyzed. The ADCmin of tumor parenchyma, the mean ADC values of proximal peritumor, distal peritumor and contralateral white matter were detected and compared to explore the variation rules of ADC values in different regions.Results:Of the 15 cases of PCNSL, 14 cases were single and 1 case was multiple, with a total of 21 lesions. (1) Single lesions in rare sites: 4 cases in the superficial part of the brain, 1 case in the bridge arm, 1 case in the cerebellar hemisphere, 1 case in the suprasellar saddle, and 1 case in the third ventricle. (2) Atypical MRI findings: cystic degeneration or necrosis in 5 lesions (5/21), accompanied by hemorrhage in 1 lesion (1/21); There were 3 isosensitive lesions on DWI, and isosensitive lesions on ADC false color images. There were 5 ring enhancement lesions and 3 sheet enhancement lesions. (3) Multi-center growth pattern: 1 case with a total of 7 lesions, located in the right thalamus, basal ganglia and corona radiata, showing multiple nodules and ring enhancement. 1H-MRS examination showed that choline (Cho) peak increased, creatine (Cr) peak decreased, N-acetyl aspartate (NAA) peak decreased, and obvious Lip peak appeared in all the 3 cases with single lesions. 2 cases showed high Lip peak as the first peak. The ADCmin values of tumor parenchyma, proximal peritumor, distal peritumor and contralateral white matter showed a parabola pattern of first rise and then decline, as follows: (0.54±0.06)×10 -3 mm 2/s, (1.55±0.10)×10 -3 mm 2/s, (1.45±0.09)×10 -3 mm 2/s, (0.85±0.03)×10 -3 mm 2/s, overall difference was statistically significant ( F=630.570, P<0.001). The pairwise comparison was statistically significant (all P<0.05). Conclusions:Atypical PCNSL is easy to be misdiagnosed. Conventional MRI feature analysis combined with DWI and MRS imaging features and comparison of ADC values in different tumor areas are helpful for the diagnosis and differentiation of PCNSL and are expected to improve diagnostic accuracy.

ABSTRACT

Objective:To investigate the effects of hydrogen rich-saline (HRS) on intestinal mucosal barrier in rat with intestinal ischemia/reperfusion injury (IIRI).Methods:Twenty-four healthy male Sprague-Dawley rats, aged 8 weeks, were randomly divided into 3 groups (8 in each group) by random number table method: sham group, model group and HRS group.Rats in HRS group were intraperitoneally injected with HRS (10 mL/kg) at 30 min of ischemia, and the same amount of normal saline was intraperitoneally injected in model group.After 45 min of ischemia and 6 h of reperfusion, rats were sacrificed.Serum and ileum were collected for further detection.Tumor necrosis factor alpha (TNF-α), interleukin (IL)- 1β and IL-17A expression levels in serum were detected by conducting enzyme-linked immunosorbent assay (ELISA). The localization expressions of tight junction protein Occludin was detected by immunohistochemical staining (IHC), while the localization expression of tight junction protein zonula occluden-1 (ZO-1) were detected by immunofluorescence staining (IF). The protein expression of Occludin, ZO-1, and Lysozyme were detected by performing Western blot.The mRNA expression of Lysozyme and α-defensin were detected by real-time PCR (qPCR).Results:ELISA results proved that the levels of serum TNF-α and IL-1β in HRS group rats were significantly lower than those in model group [(62.02±29.97) ng/L vs.(113.40±44.58) ng/L, (21.68±0.35) ng/L vs.(28.29±3.49) ng/L], while the level of IL-17A increased [(28.18±5.28) ng/L vs. (15.10±3.60) ng/L] (all P<0.05). IHC staining: compared with model group, the expression of Occludin in HRS group was uniform and continuous, and the staining was darker.IF results: compared with model group, the fluorescence signal intensity of ZO-1 in HRS group rats significantly increased, and the distribution was clear and continuous.Wes-tern blot results: compared with model group, the expression levels of Occludin and ZO-1 proteins in HRS group rats remarkably increased (0.79±0.06 vs. 0.54±0.04, 0.91±0.11 vs. 0.51±0.13), while Lysozyme protein decreased (1.50±0.40 vs. 2.99±0.80) (all P<0.05). qPCR results revealed that the expression level of Lysozyme mRNA in HRS group rats was lower than that in model group (1.64±0.33 vs. 2.20±0.40), while α-defensin mRNA obviously increased (0.82±0.19 vs. 0.47±0.13) (all P<0.01). Conclusions:HRS protects intestinal mucosal barrier by inhibiting the expression of tight junctions and the secretion of antimicrobial peptides in rat suffering from IIRI.

ABSTRACT

Objective:To investigate the effect of early debridement and open reduction combined with internal and external fixation on open fracture of tibia and fibula.Methods:The clinical data of 82 patients with open tibiofibular fractures admitted to the 901st Hospital of the Joint Logistic Support Force of the Chinese People′s Liberation Army from June 2017 to May 2018 were retrospectively analyzed. There were 42 males and 40 females, aged 20-62 years, with an average age (34.8±16.1) years. According to different surgical methods, they were divided into control group ( n=32) and observation group ( n=50). The patients in the control group received early debridement and limited internal fixation, the patients in the observation group received early debridement and open reduction combined with internal and external fixation. The operation time, blood loss, healing time, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, white blood cell count (WBC), excellent rate and complication rate were observed in both groups. The measurement data were expressed as mean±standard deviation( Mean± SD), comparison between groups was analyzed using independent sample t test, count data were expressed as percentage (%), comparison between groups was performed using chi-square test. Results:The operative time (98.35±15.14) min in the observation group were higher than those in the control group (79.26±13.22) min, blood loss (120.53±41.66) mL and healing time (16.84±5.07) min in the observation group were significantly lower than those in the control group [(79.26±13.22) min, (210.59±56.60) mL, (19.48±5.46) min]. The difference was statistically significant ( t values were 5.85, 7.76, 2.20, P<0.05). Compared with control group, the level of ESR (18.91±2.70) mm/h, CRP (39.20±3.13) ng/L, WBC (7.04±1.12)×10 3/L were significantly lower than control group [(27.36±3.28) mm/h, (45.63±4.06) ng/L, (11.06±1.51)×10 3/L]. The difference was statistically significant ( t values were 12.17, 7.63, 12.95, P<0.05). Compared with control groups′s excellent and good rate, the excellent and good rate of observation group was higher, but the difference was not statistically significant ( P>0.05). The incidence of complications in the observation group (6.00%, 3/50) was significantly lower than that in the control group (31.25%, 10/50) ( P<0.05). Conclusions:Early debridement and open reduction combined with internal and external fixation is an effective method for the treatment of open fracture of tibia and fibula. Compared with internal fixation, it has the advantages of shorter healing time, less blood loss and lower incidence of complications. And it can also reduce the inflammatory response of patients.

ABSTRACT

Diseases such as diabetes and hypertension can lead to change the shape of the retinal blood vessels. Segmentation of fundus images is a key step in the process of quantitative analysis of the disease, which is instructive in the analysis and diagnosis of clinical diseases. In this paper, a method for the segmentation of retinal image vessels based on fully convolutional network (FCN) with depthwise separable convolution and channel weighting is presented. Firstly, CLAHE and Gamma correction of the green channel of the fundus image are used to enhance the contrast. Then, in order to adapt to network training, the enhanced image is divided into patches to expand the data. Finally, the depthwise separable convolution instead of the standard convolution method is used to increase the network width. Meanwhile, the channel weighting module is introduced to explicitly model the relationship between the characteristic channels in order to improve the distinguishability of the features. The combination of them is applied to the FCN and the results of expert manual identification are used to supervise the experiment on the DRIVE database. The results show that the segmentation accuracy of the proposed method in DRIVE database reached 0.963 0 and AUC reached 0.983 1. The segmentation accuracy in STARE database reached 0.962 0 and AUC achieved 0.983 0. To some extent, the proposed method has better feature resolution and better segmentation performance.

ABSTRACT

Colon cancer is one of the common malignant tumors of digestive system.In our previous study, it has been demonstrated that colon cancer specific antigen thioredoxin like-2b (Txl-2b) can interact with Ras-related nuclear protein (Ran).However, there are few reports about the role and mechanism of Ran in tumorigenesis of colon cancer.Aims: To investigate the effect of Ran-targeting RNA interference on apoptosis and expressions of caspase-3 and poly(ADP-ribose) polymerase (PARP) in colon cancer cell lines.Methods: 20, 40 and 60 nmol/L siRNA-1 (si-1 group), siRNA-2 (si-2 group), siRNA-3 (si-3 group) targeting to Ran gene and normal control siRNA (NC group) were transfected into colon cancer cell line HCT116 and DLD-1, respectively.The interference efficiency of siRNAs and expressions of caspase-3 and PARP were detected by Western blotting.Cell apoptosis was determined by flow cytometry.Results: 20 nmol/L siRNA-1 and siRNA-2 had the best effect on inhibiting expression of Ran.Early apoptosis rates of HCT116 and DLD-1 cells in si-1 group were significantly higher than those in NC group (19.37%±7.57% vs.4.83%±1.72%;16.53%±3.38% vs.6.27%±3.13%;P all <0.05).Late apoptosis rates of HCT116 and DLD-1 cells in si-1 and si-2 groups were significantly higher than those in NC group (15.97%±3.31%, 16.33%±5.40% vs.6.40%±1.05%;22.93%±1.57%, 11.50%±0.70% vs.6.20%±0.98%;P all <0.05).Compared with NC group, expressions of cleaved caspase-3 (active form) and cleaved PARP (inactive form) were significantly increased in DLD-1 cells of si-1 and si-2 groups.Conclusions: Silencing Ran gene can significantly promote the apoptosis of colon cancer cells, and its mechanism is related to the regulation of caspase-3 and PARP expression.

ABSTRACT

Objective To detect miR-181d expression levels in colon cancer cell lines,and to study the functions of miR-181d on colon cancer cell proliferation and apoptosis.Methods RT qPCR was employed to study miR-181d cxpression levels in colon cancer cell line HCT116,HT29,LoVo,SW480 and SW620 cells,as well as in colon normal epithelial cell line HIEC.miR-181d mimic and control were transfected into LoVo cells while miR-181d inhibitor and control were transfected into SW620 cells.qRT-PCR was performed to validate the transfection efficiency.MTT assay was performed to measure cell proliferation while flow cytometry was performed to detect cell cycle and apoptosis rate.Results miR-181d was universally downregulated in all colon cancer cell lines compared to the colon normal epithelial cell line HIEC (F=29.34,P<0.01).Overexpression of miR-181d in LoVo cells significantly decreased in vitro cell proliferation rate (F=5.403,P<0.01).Flow cytometry indicated that cells at S phase were greatly decreased (t=4.71,P<0.05) and apoptotic cells were gready increased compared to the control cells (t=3.47,P<0.05).On the contrary,inhibition of miR-181d in SW620 cells significantly promoted cell proliferation (F=20.82,P<0.01).Cell cycle was accelerated with significant increase in S phase compared to the control cells (t=2.92,P<0.05),whereas apoptosis rano was significantly decreased (t=4.14,P<0.05).Conclusion miR-181d was universally downregulated in colon cancer cell lines compared to the normal epithelial cell line.miR-181d inhibits cell proliferation and induces apoptosis,thus functions as an tumor suppressive miRNA.

ABSTRACT

Objective To investigate the expression of inositol requiting enzyme1 α (IRE1 α) and tumor necrosis factor receptor-associated factor 2 (TRAF2) and its significance through establishing models of intestinal ischemia reperfusion injury (IIRI) in rats.Methods According to the random number table,50 male SD rats were randomly divided into 2 groups:sham operation group (n =10) and ischemia reperfusion (I/R) group (n =40).Sham group animals underwent laparotomy.I/R group rats were subjected to occlusion of the superior mesenteric artery for 30 min;then the blood flow was restored.I/R group animals were divided into 4 subgroups:2 h,6 h,12 h,24 h according to the time of reperfusion.Eight rats were examined based on the number of live rats in each subgroup.The HE staining pathological changes in intestinal samples were observed by the light microscope.The small intestinal epithelial cell apoptosis index (AI) was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL).The expression levels of intestinal tissues tumor necrosis factor α (TNF-α) and plasma intestinal fatty acid-binding protein (Ⅰ-FABP) were detected by ELISA tests.Situ end labeling method was used to detect intestinal cell AI.Western blot was applied to investigate the expression of endoplasmic reticulum stress(ERS) proteins IRE1α,phosphorylation IREIα (p-IRE1 α) and TRAF2 in all group rats intestinal tissues.Results (1)The pathological changes showed that the intestinal injury of I/R groups was more severe than that of sham group,especially at 6 h.(2) Compared with sham group,the expression levels of TNF-α [sham group (16.41 ± 4.44)ng/ L,2 h group:(79.71 ± 8.20) ng/L,6 h group:(131.70 ± 11.59) ng/L,12 h group:(94.23 ±7.66) ng/L,24 h group:(69.78 ± 9.58) ng/L],AI[sham group:(3.93 ±0.77)%,2 h group:(16.24 ± 1.97)%,6 h group:(42.19 ±2.40)%,12 h group:(37.79 ± 2.34)%,24 h goup:(10.38 ±1.46)%] and plasma Ⅰ-FABP [sham group:(0.65 ±0.10) × 103 ng/L,2 h group:(1.47 ±0.10) ×103 ng/L,6 h group:(2.36 ±0.17) ×103 ng/L,12 h group:(37.79 ±2.34) ×103 ng/L,24 group:(l.41 ±0.09) × 103 ng/L] were higher (F =231.462,149.032,162.491,all P < 0.01).(3) The expression of TRAF-2 protein and p-IRE1 α/IRE1 α could be up-regulated after IIRI (F =40.473,59.59,P < 0.01).The expression of these proteins was up-regulated 2 h after reperfusion,peaking at 6-12 h reperfusion,and then decreased at 24 h,and the variation tendencies of all groups were the same.Conclusions IIRI could induce ERS,activate IRE1 α and up-regulate TRAF2.IRE1α/TRAF2 mediating ERS might be involved in regulating the cell inflammation,apoptosis and increasing intestinal permeability after IIRI.

ABSTRACT

Objective To describe the association between age and the sex-based outcome difference and analyze the potential mechanism responsible for sex-based outcome difference in severe trauma patients.Methods A retrospective analysis derived from the Emergency Intensive Care Unit of the acute trauma center of the Shanghai Municipal Sixth People's Hospital during the 2010-2013 period was performed to identify sex-based outcome differences after severe blunt trauma.The study cohort of patients was then stratified by age:(1) 18 years ≤ age <45 years,(2) 45 years ≤ age ≤ 55 years,and (3) age >55 years.Crude and adjusted odds ratios (ORs) were calculated to evaluate the association between gender and the hospitalized mortality,both overall and subgroups according to age categories.Results A total of 987 severe trauma patients met our inclusion criteria were enrolled in this study.Crude mortality was higher in male severe trauma patients (male 9.1% vs.female 5.0%,P < 0.05).Multiple logistic regression revealed that females had a 79% decrease in hospitalized mortality compared with males (OR =0.21,95% CI:0.07-0.64,P =0.006).This difference was most distinct in patients with age < 45 years,(OR =0.15,95% CI:0.04-0.67,P =0.012).There is no significant difference between genders in mortality of trauma patients with 45 years ≤ age ≤ 55 years and age > 55 years.Conclusions The present study revealed a statistical significant association between gender and mortality among severe blunt trauma patients,particularly in patients with age < 45 years.These results may highlight the importance of sex hormones in outcomes of severe trauma.

ABSTRACT

Objective To investigate the effects of Baicalin on intestinal mucosal injury in rats with partial common bile duct ligation (PCBDL).Methods Forty male Wistar rats were randomly divided into 4 groups equally:sham operation,PCBDL,PCBDL1 and PCBDL2.Rats in PCBDL,PCBDL1 and PCBDL2 groups were subjected to partial common bile duct ligation.Baicalin [80 mg/(kg · d)] was fed in PCBDL1 group (for 2 weeks) and PCBDL2 group (for 3 weeks),while for other groups,9 g/L saline in the same volume was fed.Ileum mucosa were prepared for microscopic examination.The intestinal mucosal injury in rats was observed and scored.The level of NF-κB mRNA expression by Fluorescent in Situ Hybridization,and the level of NF-κB protein were determined by immunohistochemistry.Results 1.Compared with PCBDL group (3.2 ± 0.5),the pathological severity scores of intestinal mucosa significantly declined (F =21.120,P < 0.01) in PCBDL1 group (1.9 ± 0.2) and PCBDL2 group (1.5 ± 0.3).2.Compared with sham operation group(0.066 ± 0.006),PCBDL1 group (0.107 ± 0.011),and PCBDL2 group (0.098 ± 0.010),NF-κB expression in PCBDL group (0.155 ± 0.012) presented significantly up-regulation (F =76.8,P < 0.01).3.Compared with sham operation,PCBDL1 group,and PCBDL2 group,the positive expression rates of NF-κB mRNA of intestinal mucosal epithelium in PCBDL group significantly increased.Conclusions It is suggested that Baicalin exert protective effects on the intestinal mucosal injury in rats with PCBDL,partially by inhibiting NF-κB mRNA,down-regulating NF-κB protein expression of intestinal mucosal epithelial cells.

ABSTRACT

The main feature of acute steroid-resistant rejection (ASRR) after liver transplantation is a lack of response to steroids.Although some effective immunosuppressants are available,there is no uniform treatment presently available.This paper will focus on exploring the mechanism of ASRR and formulating individually approached strategies.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the efficacy of quick meridian needling therapy plus scalp acupuncture on infantile cerebral palsy (CP).</p><p><b>METHODS</b>One hundred and forty-seven cases of CP were randomly divided into a quick meridian needling therapy plus scalp acupuncture group (group A), a conventional acupuncture group (group B) and a scalp acupuncture group (group C), 49 cases in each one. In group A, quick needling was applied to the Conception Vessel, Governor Vessel, Hand-Yangming, Hand-Jueyin, Foot-Yangming and Foot-Taiyin meridians distributed on four limbs and trunk. One pricking point was 10 mm far from the other one. In scalp acupuncture, motor area, equilibrium area, sensory area, tremor-control area, foot-motor-sensory area, speech No. 2 area, speech No. 3 area, Baihui (GV 20), Sishencong (EX-HN 1), etc. were selected. The needles were stimulated with rotating manipulation and remained for 30-60 min. In group B, the conventional acupuncture was adopted mainly at Dazhui (GV 14), Shenzhu (GV 12), Fengfu (GV 16) and others. In group C, the scalp acupuncture was used and the points selected were same as those in group A for scalp acupuncture treatment. The scores of Gross Motor Function Measure (GMFM) were observed before and after treatment for children. The clinical efficacy of each group was evaluated. By follow-up for 12 months, the condition of independent walking was observed.</p><p><b>RESULTS</b>The total effective rate in group A was 79.6% (39/49), which was superior to that of group B [49.0% (24/49)] and group C [51.0% (25/ 49)] respectively (both P < 0.05). After treatment, GMFM scores of children were all improved significantly in 3 groups (P < 0.001, P < 0.05), of which, the improvement extent in group A was superior to that of other two groups (both P < 0.05). It was found after follow-up for 1 year that 31 cases could walk independently in group A, which was more than group B (17 cases) and group C (16 cases).</p><p><b>CONCLUSION</b>The quick meridian needling therapy plus scalp acupuncture can improve significantly limb motor function of children with cerebral palsy and its therapeutic effect is superior to conventional acupuncture and simple scalp acupuncture.</p>
