Objective To study the effect of cognitive dysfunction of gangliosides on in the treatment of the patients with traumatic brain injury intraoperative and postoperative. Methods From February 2015 to August 2016, 100 patients with cognitive dysfunction after operation were randomly divided into two groups, the control group and the experimental group, 50 cases in each group. The control group were received routine treatment, including medication, brain rehabilitation, and dehydration and intracranial pressure reduction. At this basis, the experimental group were treated with gangliosides. The clinical indexes in the experimental group and the control group were compared and analyzed. Results The cure rate was 90% in the experimental group, and 54% in the control group. The difference in the two groups has statistically significant (P<0.05). Before treatment, there was no significant difference of the MMSE in the two groups. After treatment, the MMSE score in the experimental group was (28.34 ± 4.12) points, and the score of MMSE in the control group was (22.19 ± 5.49) points. The difference in the two groups has statistically significant (P<0.05). Conclusion The effect of cognitive dysfunction is better which ganglioside was used on the treatment of the patients with traumatic brain injury intraoperative and postoperative, and the cure rate is higher. It has the significance of further popularization and application.

AIM: To detect the effect of intercellular adhesion molecule-1(ICAM-1) monoclonal antibody on microcirculation disorder in burn shock of Wistar rats. METHODS: The blood flow velocity and diameter of venule were measured with RBC tracking correlator and IV550 model video microscaler in burn shock models of rats. The number of leukocytes adhered on venule wall was calculated under microscope. The animal survival time was observed. RESULTS: ICAM-1monoclonal antibody could attenuate the falling of mean arterial pressure, significantly reduce the number of leukocytes adhered on venule wall, and obviously prolong the animal mean survival time, but less than 24h. CONCLUSION: ICAM-1 monoclonal antibody can decrease the number of adhered leukocytes to endothelial cells, attenuate the tether of leukocytes to venule and improve microcirculation and protect tissue cells in burn shock of rats. However, a comprehensive therapy should be taken in severe shock.

AIM: To elucidate the mechanism of polydatin(PD) in increasing the contractility of myocardial cells by observing the cytosolic free calcium concentration ([Ca 2+ ]i) of myocardial cells of rats. METHODS: The cells were labelled with fluo-3-AM, and [Ca 2+ ]i was determined by use of confocal microscopy (ACAS 570). RESULTS: In the study, we found that [Ca 2+ ]i of myocytes was elevated 10min after adding PD (0.6 mmol/L), but [Ca 2+ ]i of some cells increased to 111.80%?2.22% vs baseline, the others to 224.00%?24.33%. The effect of PD was inhibited remarkably by pretreated with EGTA(2mmol/L), verapamil (50 ?mol/L), a kind of L-calcium channel antagnist, and tetrodotoxin ( 1 ?mol/L), a kind of sodium channel blocker 10 min before PD, the fluorescence value were decreased to 53.00%?9.02% , 52.00%?7.07% and 72.67%?12.70% respectively vs baseline (P

Objective To evaluate the feasibility of Mycobacteria growth indicator tube ( MGIT ) liquid culture combined with rifampin resistance test real-time PCR ( Xpert MTB/RIF test) in the diagnosis of tuberculosis.Methods 652 cases of suspected pulmonary tuberculosis from October 2014 to March 2015 in Quzhou People′s Hospital were enrolled. The morning sputum samples were collected for acid-fast staining, L?wenstein-Jensen ( L-J) culture, BACTEC MGIT culture and Xpert MTB/RIF test.Samples with positive results of MGIT liquid culture were subjected to strain identification and drug sensitivity test with fluid method.Methodological comparison between four methods was made and the performance of MGIT liquid culture combined with Xpert MTB/RIF test in the rapid diagnosis and drug resistance detection in Mycobacterium tuberculosis was evaluated by chi-square test. Results Among the samples from 399 confirmed tuberculosis patients, the diagnostic sensitivity of the 4 methods ( acid-fast staining, L-J culture, MGIT culture and Xpert MTB/RIF test) were 17.0%(68/399), 23.8%(95/399), 37.8% (151/399) and 37.3%(149/399) respectively.The sensitivity and specificity of MGIT culture combined with Xpert MTB/RIF test was 39.8%(159/399) and 94.8%(240/253).The sensitivity of MGIT culture combined with Xpert MTB/RIF test was significantly higher than acid-fast staining (χ2 =50.9, P<0.01 ) and L-J culture (χ2 =23.7,P<0.01).The average detection time of MGIT culture was 7.5 days ( smear positive and Xpert MTB/RIF positive), 13.4 days (smear negative and Xpert MTB/RIF positive) and 16.9 days ( smear negative and Xpert MTB/RIF negative) .The sensitivity and specificity of Xpert MTB/RIF test in rifampin resistance detection were 9/9 and 97.3% ( 129/132 ) respectively.The average detection time of fluid method for drug sensitivity test was 8.3 days.Conclusions MGIT liquid culture combined with Xpert MTB/RIF test can detect Mycobacterium tuberculosis and the drug sensitivity rapidly.The method is highly sensitive and specific.It is important for clinical diagnosis and treatment of tuberculosis.

ObjectiveTo determine the expression of matrix metalloproteinase-2 (MMP-2),cysteine rich protein 61 (Cyr61) and CD25 in esophageal carcinoma and investigate their clinical significance.MethodThe expression of MMP-2, Cyr61 and CD25 in 68 cases of esophageal tumor tissues (esophageal carcinoma group ) and part-cancer( para-cancer group ) and 68 cases of reflux esophagitis (control group ) was detected by immunohistochemical method and the results were statistically analysed. ResultsThe positive expression rates of MMP-2,Cyr61 and CD25 were 82.35％(56/68), 73.53％(50/68) and 89.71％(61/68)respectively in esophageal carcinoma group,there were significant differences compared with those in paracancer group and control group(P ＜ 0.05) ; while there was no significantdifference between para-cancer group and control group (P ＞ 0.05 ). The positive expression rates of MMP-2, Cyr61 and CD25 in esophageal carcinoma group in different T stage, N stage and M stage all had statisticall differences (P ＜ 0.05),while there was no significant difference in different degree of differentiation (P ＞ 0.05 ). ConclusionMMP-2,Cyr61 and CD25 is highly expressed in esophageal carcinoma,there is some significance for understanding the occurrence, development and prognosis of esophageal carcinoma.

Objective To study the vascular anatomy of duplex kidney and to provide a scientific basis for surgical resection of the renal segment.Methods From February 2012 to April 2018,the clinical data of 84 children with renal duplex kidney disease admitted to our hospital,were reviewed and analyzed.Among them,75 cases (89.3％) were unilateral and 9 cases (10.7％) were bilateral.According to the preoperative CT + CTA and the duplicated renal morphology,size,location,and anatomical relationship of the kidney segment,combined with the branches and passage of the renal artery which supplies the upper moiety,it described the blood supply of the upper renal moiety.At the same time,it analyzed various types of embryological related factors and gender differences and summarized the tips for laparoscopic surgery.Results Of the 93 duplex kidneys,69 (74.2％) were supplied with 1 artery,and 25 (26.9％) were supplied with 2 or more arteries.Based on the shape and orifice of artery,they were divided into 3 types.The most common type was that the renal artery separated into two or more arteries near the renal parenchyma.The upper and lower renal poles were respectively supplied,which could be summarized as early branching,a total of 71 sides (76.3 ％).The second type was the arteries from abdominal aorta or its branches,directly flowing into the upper renal pole,which was classified into the sub-renal artery,a total of 18 sides (19.4％).The others (4 sides,3.3％) were less common,and most of them were a combination of the above-mentioned two types,and one of them whose upper pole was supplied by branches of adrenal artery.Based on the classification of vascular variability,no significant difference was found between males and fenmals,or left and right sides.Conclusions The upper renal moiety are mainly supplied by one branch of renal artery,and the most common type of this artery is prehilar branch,without gender difference.The determination of vascular variability before surgery can avoid bleeding during surgery and avoid accidental injury of normal blood vessels.
