ABSTRACT
AIM: To study the effects of trigliptin succinate on gut microbiota of type 2 diabetic mice. METHODS: 16S rRNA high-throughput sequencing method was used to sequence the intestinal flora of mice in the healthy group, the T2DM group, the trigliptin succinate group and the sitagliptin phosphate group. QIME was used to filter the data, classify and annotate the species. Alpha diversity index and Beta diversity index of the samples were analyzed.The richness and diversity of bacteria in the four groups were compared. RESULTS: The gut microbiota structure of mice in the healthy group, the T2DM group, the trigliptin succinate group and the setagliptin phosphate group were significantly different. The results showed that the ratio of Firmicutes to Bacteroidetes was decreased compared with that in the healthy group. Cyanobacteria, Verrucomicrobia and Tenericutes had significant differences (P< 0.05). Potential biomarkers for T2DM group were Bacilli, Lactobacillales, Lactococcus and Streptococcaceae. Candidate biomarkers of trigliptin succinate group may be Bacteroidia, Bacteroidetes, Bacteroidales, Prevotella, Paraprevotellaceae, Parabacteroides, Porphyromonadaceae; The candidate biomarkers of sitagliptin phosphate group may be Lactobacillus, Lactobacillaceae and Helicobacter. CONCLUSION: The intestinal flora of mice in the trigliptin succinate group was significantly different from that in the healthy group and the T2DM group. Using trigliptin succinate to improve the intestinal flora of mice might achieve the hypoglycemic effect by improving the intestinal flora.
ABSTRACT
BACKGROUND:There is a lack of evidence about the application of extracorporeal shock wave therapy (ESVTr) in frozen shoulder contracture syndrome.OBJECTIVE:To systematically assess the effectiveness of EST for frozen shoulder.METHODS:A computer-based online search of PubMed,ScienceDirect,The Cochrane Library,Embase,Web of knowledge,CNKI,WanFang and CqVip databases was performed for articles related to ESWT for frozen shoulder published before May 10,2016.Randomized controlled trials or randomized controlled crossover trials were screened.The Meta-analysis was conducted using RevMan 5.0 software,and publication bias was assessed by Berg and Egger tests on Stata1 1.0 software.The continuous variables were expressed as standard mean difference (SMD) and 95％ confidence interval (CI),and binary variables were expressed as odds ratio (OR) and 95％ Cl.RESULTS AND CONCLUSION:Eleven trials were enrolled involving 816 participants.ESWT could effectively alleviate shoulder pain (P ＜ 0.05,/2=54％).When excluded the trials of which control groups were medical interventions,the direction of the outcome did not change.ESVVT was beneficial for the participants in terms of range of motion except extension,the changes in shoulder flexion (P ＜ 0.05,/2=28％),shoulder abduction (P ＜ 0.000 01,/2=17％),shoulder internal rotation (P ＜ 0.05,/2=0％),shoulder external rotation (P ＜ 0.05,/2=43％).However,there is no evidence of the effectiveness of ESWT versus control (conventional therapy) for improving the range of shoulder extension.ESWT could increase the efficiency of treating frozen shoulder (P ＜ 0.05,/2=0.0％) and efficacy of curing frozen shoulder (P ＜ 0.05,/2=0.0％) compared with other interventions,and with no significant difference in the drop rate.These results indicate that ESWT can effectively alleviate the pain of frozen shoulder,expand the range of shoulder flexion,abduction,internal and external rotation,as well as improve the therapeutic efficiency and cure rate in the treatment of frozen shoulder.
ABSTRACT
One cases of ectopic schistosomiasis in fallopian tube was found by the histopathological examination in Jingmen City. After surgery and anthelmintic treatment with praziquantel,the curative effect was satisfactory. This case suggests that in schistosomiasis endemic area,the imaging technology and tissue pathological examination should be used sufficiently for the dif-ferential diagnosis of ectopic schistosomiasis,so as to reduce misdiagnosis.
ABSTRACT
Objective·To explore the correlation of etomidate dose and bispectral index (BIS) in children with congenital heart disease shunting from left to right during anesthesia induction. Methods·After general anesthesia induction to 24 children with congenital heart disease shunting from left to right, sevoflurane inhaling was stopped in order to make the BIS value gradually return to 80. Intravenous injection of etomidate was sustained by 0.3 mg/(kg·min) until the BIS value reached 40. The heart rate (HR), arterial blood pressure (ABP) and central venous pressure (CVP) of the patients were recorded when BIS value was 80, 70, 60, 50,and 40, respectively.The correlation of etomidate dose and BIS value in the children during anesthesia induction was analyzed. Results·There were no significant hemodynamic changes when the BIS value were from 80 to 40. The amount of etomidate was highly negatively correlated with the BIS value (r=-0.769, P<0.01), the average dose of etomidate in children under 2 years of age was significantly higher than that in children over 2 years old (P=0.034). Conclusion·The etomidate dose is highly negatively correlated with the BIS value. Etomidate has less influence on hemodynamic parameters of children with congenital heart disease shunting from left to right. The BIS value may have relationship with patients'age.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the methods for the therapeutic effect improvement in the treatment of post-stroke urinary retention.</p><p><b>METHODS</b>Sixty-three patients of post-stroke urinary retention were randomized into an observation group (32 cases) and a control group (31 cases). The routine clinical medication of neurology and basic rehabilitation were adopted in the two groups. Additionally, in the control group, the intermittent urinary catheterization and bladder function training were applied. The duration and frequency of catheterization were determined by the autonomic urination and residual urine volume every day. In the observation group, on the basis of the treatment as the control group, acupuncture was applied to the twelve-well points in the sequence offlowing among the twelve meridians [Shaoshang (LU 11), Shangyang (LI 1), Lidui (ST 45), Yinbai (SP 1), Shaochong (HT 9), Shaoze (SI 1), Zhiyin (BL 67), Yongquan (KI 1), Zhongchong (PC 9), Guanchong (TE 1), Zuqiaoyin (GB 44) and Dadun (LR 1)]. Acupuncture was given once a day, 20 treatments were required. In 20 treatments, the clinical therapeutic effects and the residual urine volume were observed.</p><p><b>RESULTS</b>The total effective rate was 90.6% (29/32) in the observation group, better than 67.7% (21/31) in the control group (<0.01)). After treatment, the residue urine volume was all reduced apparently in the patients of the two groups (both<0.01). The result of the residue urine volume in the observation group was lower apparently than that in the control group (<0.01).</p><p><b>CONCLUSION</b>Acupuncture at the-well points in the sequence offlowing among meridians combined with bladder function training achieve the apparent therapeutic effects on post-stroke urinary retention. The results are better than those achieved by the routine western medicine with bladder function training involved.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between lipid accumulation and autofluorescence intensity of injury site after spinal cord injury (SCI), and explore whether CuSO⁴ can eliminate autofluorescence in the injury site after SCI.</p><p><b>METHODS</b>Thirty six Wild Type mice at age of 8 to 12 weeks (weight 18 to 24 g) were randomly divided into normal control group (4) and SCI group (32). Respectively, 8 mice of SCI group were sacrificed randomly at 1 week, 2 weeks, 4 weeks and 8 weeks after injury. Frozen sections of spinal cord tissue with injury site at the center were made to observe autofluorescence under green channel of fluorescence microscope (Specimens of normal control group were taken from the same segment of the spinal cord, and fixed with 4% paraformaldehyde solution). Oil Red O staining was applied to visualize the lipid accumulation in the injury site, and correlation between lipid accumulation and autofluorescence intensity was analyzed. Furthermore, sections were incubated with CuSO⁴ buffer to eliminate autofluorescence, and CuSO⁴ concentration and incubation time was optimized.</p><p><b>RESULTS</b>No obvious autofluorescence or lipid staining was found in normal spinal cord tissue sections. By contrast, autofluorescence appeared in the injury site of spinal cord sections, and the intensity increased with passing time after injury. Oil Red O staining showed that lipid accumulated in the injury site with passing time after injury as well, and the correlation between lipid accumulation and autofluorescence intensity was positive. After incubation with CuSO⁴ buffer, the autofluorescence in the injury site was significantly reduced, especially after optimizing CuSO⁴ concentration and incubation time.</p><p><b>CONCLUSIONS</b>Lipid accumulation may play an important role to determine the autofluorescence intensity of injury site after SCI, and the autofluorescence intensity can be used as a simple index for evaluating lipid peroxidation damage. Optimized method of using CuSO⁴ can significantly reduce the autofluorescence in the injury site after SCI, which will be beneficial to the application of immunofluorescence staining technique in the study of SCI.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To compare the differences in the clinical efficacy on post-stroke speech disorder between scalp electric acupuncture (EA) under anatomic orientation combined with rehabilitation training and simple rehabilitation training.</p><p><b>METHODS</b>Sixty patients of post-stroke speech apraxia were randomized into an observation group and a control group, 30 cases in each one. In the observation group, under anatomic orientation, the scalp EA was adopted to the dominant hemisphere Broca area on the left cerebrum. Additionally, the speech rehabilitation training was combined. In the control group, the speech rehabilitation training was simply,used. The treatment lasted for 4 weeks totally. The speech movement program module in the psychological language assessment and treatment system of Chinese aphasia was used for the evident of efficacy assessment. The scores of counting, singing scale, repeating phonetic alphabet, repeating monosyllable and repeating disyllable were observed in the patients of the two groups. The assessment was done separately on the day of grouping and 4 weeks after treatment.</p><p><b>RESULTS</b>In 4 weeks of treatment, the scores of counting, singing scale, repeating phonetic alphabet, repeating monosyllable and repeating disyllable were all improved as compared with those before treatment in the two groups (all P<0. 001). The results in the observation group were better than those in the control group (all P< 0. 05). The total effective rate was 100. 0% (30/30) in the observation group, superior apparently to 53. 3% (16/30) in the control group (P<0. 001).</p><p><b>CONCLUSION</b>The scalp EA under anatomic orientation combined with' speech rehabilitation training obviously improves speech apraxia in stroke patients so that the speech disorder cani be relieved. The efficacy is better than that in simple rehabilitation training.</p>

<p><b>INTRODUCTION</b>Liver biopsy is considered the definitive investigation in the diagnosis and management of liver disease. This study describes the experience of performing transjugular liver biopsy (TJLB) over the last 9 years in a local single centre.</p><p><b>MATERIALS AND METHODS</b>A retrospective review of consecutive TJLB procedures performed at our institution was conducted. A total of 152 patients (74 males and 78 females), with a mean age of 47.4 years (range, 13 to 83 years) underwent a total of 154 TJLB procedures at our institution between March 2003 and November 2011. The principal indication for TJLB was severe coagulopathy in over 80% of patients. The technical success, number of passes, histological adequacy and complication rates were analysed.</p><p><b>RESULTS</b>The procedural success rate was 98.7% (152 out of 154 procedures). Adequate material for diagnosis was obtained in 149 out of 152 (98.0%) technically successful procedures. There was procedure related morbidity in 8 patients (5.2%) of which all but one were self-limiting requiring no further intervention. We also performed hepatic venous pressure gradient (HVPG) measurements in 19% of patients at the time of TJLB.</p><p><b>CONCLUSION</b>TJLB performed at our institution is a safe and reliable technique in patients in whom traditional percutaneous liver biopsy may be hazardous. TJLB has a high technical success rate as well as a high diagnostic yield with a low complication rate. TJLB also has the added benefit of performing HVPG, which is of increasing importance in management and prognostication of chronic liver disease.</p>
