Objective To evaluate the effect of tranexamic acid (TXA ) in medical treatment of chronic subdural hematoma (CSDH) .Methods A total of 19 patients with CT-confirmed CSDH in our department from Mar 2014 to Aug 2015 received an in-travenous dose of 1g TXA in the first week ,and followed by a maintenance oral dose of 250 mg TXA three times a day for 1 - 5 months (2 .73 ± 1 .05) months .These patients received a follow-up period of 6 - 10 months .Hematoma volume and neurological functions were compared before and after treatment .Results The therapeutic outcome was divided into effectiveness and ineffec-tiveness .Thirteen cases (68 .4% ) were effective ;six cases (31 .6% ) were ineffective .Among them ,three patients (15 .8% ) whose neurological functions deteriorated underwent surgery ,one patient (5 .3% ) who did not show any improvement with initial one month of TXA underwent surgery ,one patient (5 .3% ) stopped the treatment due to the side-effect of drug ,one patient (5 .3% ) lost .Conclusion Results of this preliminary study show that the administration of TXA is effective and safe in treating CSDH .

As a member of nuclear receptor superfamily, farnesoid X receptor (FXR) has been shown to regulate numerous metabolic pathways, which include playing an important role in bile acid metabolism, maintaining lipid and glucose homeostasis when FXR is activated. With the prevalence of the glucose and lipids disorder, FXR attracts increasing attention. It may be a potential target for the treatment of type 2 diabetes mellitus and lipid disorders.

Objectives To compare the effectiveness and safety of local anesthesia and epidural anesthesia with ureteroscopic pneumatic lithotripsy at distal ureteral stone. Methods A total of 160 patients with distal ureteral stone treated with ureteroscopic pneumatic lithotripsy from December 2013 to February 2014 were included. They were divided equally into 2 groups by method of random sampling. Patients in group A (n=80) treated with local anesthesia were compared to those in group B(n=80),who were dealt with epidural anesthesia. Results The statistical difference was significant in terms of hospital stay after operation and overall cost of therapy(P<0. 05) respectively,on the other hand,it was not significant in respect of the operation time,the operation successful rate,the stone clearance rate and the complications incidence rate (P>0. 05)respectively. Conclusion For the identified patients,the local anesthesia in ureteral ureteroscopic pneumatic lith-otripsy is a safe,effective and economical method for distal ureteral stone.

Objective To investigate the effects of cold preservation on the expression of GATA in intrahepatic bile duct.Methods The intrahepatic bile duct tissues of SD rats were obtained by collagenase perfusion combined with mechanical separation.After being cut into fragments,the intrahepatic bile duct tissues were cultured in rat tail collagen gel for 48 hours before experiment.All the rats were divided into the control group,cold preservation 1 hour (CP1 h) group and cold preservation 12 hours (CP12 h) group.There were 5 rats in each group.The mRNA and protein expressions of GATA were detected by Real-Time polymerase chain reaction and Western blot.Measurement data with normal distribution were presented as (x) ± s.Comparison among 3 groups was done by ANOVA and pairwise comparisons were done by LSD test.Results The mRNA expressions of GATA3,GATA4,GATA6 were detected,while the mRNA expressions of GATA1,GATA2 and GATA5 were undetectable in intrahepatic bile duct tissue of the control group.The mRNA expressions of GATA4 in the CP1 h group,CP12 h group and the control group were 0.72 ± 0.08,0.56 ± 0.07 and 0.96 ± 0.06,with significant difference among the 3 groups (F =38.981,P ＜0.05).The mRNA expression of GATA4 in the CP12 h group was significantly lower than that in the CP1 h group and the control group,and the mRNA expression of GATA4 in the CP1 h group was significantly lower than that in the control group (P ＜ 0.05).The mRNA expression of GATA6 in the CP1 h group,CP12 h group and the control group were 0.83 ± 0.07,0.68 ± 0.12 and 0.98 ± 0.12,with significant difference among the 3 groups (F =10.175,P ＜ 0.05).The mRNA expression of GATA6 in the CP12 group was significantly lower than that in the CP1 h group and the control group,and the mRNA expression of GATA6 in the CP1 h group was significantly lower than that in the control group (P ＜ 0.05).The mRNA expressions of GATA3 in the CP1 h group,CP12 h group and the control group were 0.92 ± 0.06,0.89 ± 0.05 and 0.98 ± 0.11,with no significant difference among the 3 groups (F =1.674,P ＞ 0.05).The protein expressions of GATA4 in the CP1 h group,CP12 h group and the control group were 0.78 ± 0.07,0.64 ± 0.06 and 0.99 ± 0.10,with significant difference among the 3 groups (F =24.211,P ＜ 0.05).The protein expression of GATA4 in the CP12 h group was significantly lower than that in the CP1 h group and the control group,and the protein expression of GATA4 in the CP1 h group was significantly lower than that in the control group (P ＜ 0.05).The protein expressions of GATA6 in the CP1 h group,CP12 h group and the control group were 0.90 ± 0.04,0.75 ±0.06 and 0.98 ±0.11,with significant difference among the 3 groups (F=11.651,P＜0.05).The protein expression of GATA6 in the CP12 h group was significantly lower than that in the CP1 h group and the control group (P ＜ 0.05).Conclusion The expressions of GATA4 and GATA6 in the intrahepatic bile duct tissues are decreased significantly after cold preservation,which indicate that GATA4 and GATA6 might be involved in the pathophysiological process of the bile duct after cold preservation.

Objective:To examine the expression and function of thrombonspondin-1 (TSP-1) in oxygen-induced retinopathy in new-born mice, and to investigate its role in retinal neovascularization. Methods:A total of 40 C57BL/6J newborn mice were divided equally into a model group (n=20)andanormalcontrolgroup(n=20).Miceinthemodelgroupwereexposedto75%oxygentoestablish the oxygen-induced retinopathy (OIR) model. On the 7th, 9th, and 11th day after the birth of mice, 5 mice were randomly selected each time from the 2 groups to examine the expression of TSP-1 mRNA with reverse transcription polymerase chain reaction (RT-PCR). After that, 5 mice were selected on the 11th day to observe the retinal neovascularization by fluorescein angiography retinal flatmount. Results:On the 11th day, fluorescein angiography retinal flatmount showed that the retinal blood vessels presented mean network distribution in the normal control group, while in the model group, a lot of dilatated areas in the retinal main vessels surrounded the optic disc. Meanwhile lots of new blood vessels were found surrounding the optic disc with irregular distribution but well distributed peripherial retinal small vessels, which was typical of early stage OIR. There was no signiifcant difference in the retinal TSP-1 mRNA level between the model group and the normal control group in the postnatal 7-day mice (P>0.05). Compared with the normal control group, the expression of TSP-1 mRNA in the model group was signiifcantly lower in postnatal 9-day and 11-day mice (P<0.05, P<0.01) , and the expression of TSP-1 mRNA in postnatal 9-day mice was lower than that in the postnatal 11-day mice(P<0.05).
Conclusion:In the early stage of OIR model (retinal vascular growth and development stage), the expression of TSP-1 mRNA in the retinal tissue is gradually decreased, implying that TSP-1 (as a negative regulatory factor) may be involved in the formation of retinal neovascularization in the early stage.
