Objective To make a comparative assessment on both the therapeutic effects and side effects between percutaenous lauromacrogol injection therapy(PLIT) and percutaenous ethanol injection therapy(PEIT) for simple hepatic or renal cyst.Methods In group A,55 patients with simple hepatic or renal cysts underwent ultrasound-guided aspiration and successive PLIT.The intra-operative side effects were investigated and the therapeutic effects assessment by using ultrasonography was conducted 3 months after the treatment.In group B,60 patients with simple hepatic or renal cysts had received ultrasound-guided aspiration and PEIT sometime before.The intra-operative side effects and therapeutic effects on the thirdmonth ultrasonography were independently reviewed according to their case records.Results In group A,3 patients(5.5 ％) expressed slight discomfort but not pain while receiving lauromacrogol injection.Follow-up ultrasound examination at the end of third month demonstrated the cysts in 43 patients completely regressed,while cysts in rest 12 patients shrank over 50 ％ in size,showing the overall response rate(ORR) and completely cure rate(CCR) were 100％ (55/55) and 78.2％ (43/55) for PLIT respectively.In group B,12 patients(20％) suffered from slight to moderate irritating pain or drunk performance.The third-month ultrasound examination disclosed that cysts in 47 patients completely vanished,and cysts in the other 13patients shrank more than a half,indicating the ORR and CCR were 100％ (60/60) and 78.3 ％ (47/60) for PEIT respectively.Conclusions Although their therapeutic efficacy are perfectly similar,PLIT is much more superior to PEIT in term of less and minor side effects.

Objective To investigate the effects of intravitreal injection of conbercept on diffuse macular edema (DME) of diabetes mellitus.Methods Together 51 diabetic patients (51 eyes) with diffuse macular edema were collected between July 2016 to July 2017,and randomly divided into three groups (n =17):group A,in which patients received solely intravitreal injection of 0.5 mg conbercept,group B,those who was intravitreally injected with 0.5 mg of conbercept and modified macular grating photocoagulation,and group C,patients undergoing modified grid photocoagulation (GPG).Then,before treatment and 1 week,1 month,3 months and 6 months after treatment,all patients were examined by optical coherence tomography for determining central macular thickness (CMT),followed by fundus fluorescein angiography (FFA),the best corrected visual acuity (BCVA),slit lamp,intraocular pressure for compare the efficacy and safety of the three procedures.Results All the three treatments improved BCVA,CMT,retinal neovascularization (RNV) leakage in diffuse DME patients,but group A and B were better than group C (both P ＜ 0.05),while there was no significant difference in BCVA improvement between A and B group (P ＞ 0.05),whereas the improvement in CMT of group B patients was better than that of group A [(197.47 ±45.26) μm vs.(205.59 ± 47.33) μm] (P ＜ 0.001),and this was true of RNV leakage [(9.91 ±3.18)mm vs.(13.24 ±4.87) rnm] (P＜0.001),without related complications.Conclusion Combination of modified macular grid photocoagulation and intravitreal injection of conbercept can quickly relieve diabetic macular edema and alleviate neovascularization,thus improving the patients' vision acuity,of which the efficacy is superior to the pure modified macular grid photocoagulation and conbercept injection.

OBJECTIVETo establish an HPLC fingerprint to evaluate the quality of Polygalae Radix, root xylem, and those collected in different growth ages or harvest time.

METHODSeparation was performed at 30 °C on a Kromasil C18 column (4.6 mm x 250 mm, 5 μm); the mobile phases was acetonitrile and 0.05% H3PO4 water in the gradient elution; the flow rate was set at 1.0 mL · min(-1) and the detection wavelength at 314 nm; the quality discriminant analyses were accomplished by means of similarity analysis, cluster analysis, principal component analysis and neural network model.

RESULTIn 26 batches of Polygalae Radix, 24 batches fingerprint similarities were above 0.8. In 5 different growth or harvest time batches, 4 batches were above 0.8; in 8 batches root xylem samples, the similarities were all above 0.875. The similarity analysis was in accord with the quality discriminant analysis of cluster analysis, principal component analysis and neural network model.

CONCLUSIONFingerprint combined with chemical pattern recognition technique can effectively evaluate the quality of Polygalae Radix. The active substance species are all similar in cultivated, wild, different growth or harvest time Polygalae Radix and polygala root xylem, but the chromatography peak areas are different. The effective material contents are similar between wild and cultivated Polygalae Radix, but each chromatographic peak area of the root xylem is much smaller than that of Polygalae Radix. The chemical substance accumulation mainly depends on harvest month, but little growth time in Polygalae Radix.

To carry out pathologic diagnoses and whole-genome sequence analyses of the Jaagsiekte sheep retrovirus (JSRV) in Xinjiang, China, we first observed sheep suspected to have the JSRV. Then, the extracted virus suspension was observed by transmission electron microscopy (TEM). Total RNAs from lungs of JSRV-infected sheep were extracted and reverse-transcribed using a cDNA synthesis kit. Six pairs of primers were designed according to the exogenous reference virus strain (AF105220). Reverse transcription-polymerase chain reaction was carried out from JSRV-infected tissue, and the whole genome of the JSRV sequenced. Our results showed: flow of nasal fluid ("wheelbarrow test"); different sizes of adenoma lesions in the lungs; papillary hyperplasia of alveolar epithelial cells; alveolar cavity filled with macrophages; dissolute nuclei in central lesions. TEM revealed JSRV particles with a diameter of 88 nm to 125. 4 nm. The full-length of the viral genome sequence was 7456 bp. BLAST analyses showed nucleotide homology of 96% and 95% compared with that of the representative strain from the USA (AF105220) and UK (AF357971). Nucleotide homology was 89.8% and 89.9% compared with the endogenous Jaagsiekte sheep retrovirus, Inner Mongolia strain (DQ838493) and USA strain (EF680300). The specific pathogenic amino-acid sequence "YXXM" was found in the TM district, similar to the exogenous JSRV: this gene has been reported to be oncogenic. This is the first report of the complete genomic sequence of the exogenous JSRV from Xinjiang, and could lay the foundation for study of the biological characteristics and pathogenic mechanisms of the pulmonary adenomatosis virus in sheep.

Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa

ObjectiveTo observe the injured changes of brain myelin sheath structure and myelin basic protein (MBP) content induced by amyloid β peptide (Aβ) and effect of GETO on these changes.MethodsThe experimental rat model of Alzheimer's disease was established with Aβ1-42 injection into hippocampus. 4 weeks later, the myelin sheath structure of the CA1 area of the rat hippocampus was taken and observed by electromicroscope, and distribution and content of MBP were examined with immunohistochemical method.ResultsThe electromicroscope showed that the structure of myelin sheath became relaxing, disorder, homogenization and default of hippocampus CA1 in the model rats. In GETO treated group, the structure of myelin sheath was integrity and continuum. Immunohistochemical test showed that the staining and numbers of myelin sheath of model rats was thinner than that of normal rats and GETO treated rats. The numbers, mean area and mean density of positive staining axon in hippocampus CA1 of MBP in the model rats were significantly different from those in the normal group and GETO group (P<0.01).ConclusionAβ1-42 injection into hippocampus in rats can impair myelin sheath to make MBP release and GETO can ameliorate these changes.

AIM: To assess the degree of oxidative damage during acute myocardial infarction and reperfusion, and to clarify the protective effect of Tongxinluo in mini-swine model. METHODS: Thirty mini-swines were randomized into 5 study groups: sham group, model group, low dose (0.05 g·kg~(-1)·d~(-1)), medium dose (0.2 g·kg~(-1)·d~(-1)) and high dose (0.5 g·kg~(-1)·d~(-1)) of Tongxinluo groups (pretreated with Tongxinluo for 3 d). Animals except in sham group were subjected to 3 h of coronary occlusion followed by 1 h of reperfusion. Concentrations of total antioxidative capability (T-AOC), total superoxide dismutase (T-SOD), reduced glutathione (GSH) and malondialdehyde (MDA) in blood sample and the myocardium were measured. RESULTS: (1) T-AOC, T-SOD and GSH in serum significantly decreased (all P<0.05), while MDA significantly increased (P<0.01) at 3 h after AMI in comparison with those at baseline. Compared to those at 3 h after AMI, the contents of T-AOC, T-SOD and GSH at 1 h after reperfusion significantly decreased (all P<0.01), accompanied by increase of MDA (P<0.01). (2) Compared to those in normal area, levels of T-AOC, T-SOD and GSH in reperfusion myocardium decreased significantly (all P<0.01) and MDA increased significantly (P<0.01). T-AOC, T-SOD and GSH in no-reflow myocardium further decreased (all P<0.01) and MDA increased (P<0.01) as compared to those in reperfusion myocardium. (3) Compared to model group, medium dose of Tongxinluo increased the contents of T-AOC and T-SOD and reduced MDA production in serum at 3 h after AMI (all P<0.05), while medium dose of Tongxinluo increased T-SOD level at 1 h after reperfusion (P<0.05). High dose of Tongxinluo increased the levels of T-AOC and T-SOD and decreased MDA content in serum at 3 h after AMI and 1 h after reperfusion (all P<0.05). (4) The medium dose of Tongxinluo increased T-AOC content (P<0.05) and reduced MDA (P<0.05) in reperfusion myocardium, while high dose of Tongxinluo increased T-AOC, T-SOD and GSH (all P<0.05), reduced MDA (P<0.01) in reperfusion myocardium, and also increased T-AOC, T-SOD (all P<0.05), reduced MDA (P<0.01) in no-reflow area as compared to those in model group. CONCLUSION: Impairment of antioxidant defense system in vivo and imbalance of redox homeostasis in myocardium region might play an important role in the pathogenesis of no-reflow after myocardial acute infarction following reperfusion. Tongxinluo protects myocardium from reperfusion injury by improving antioxidant defense and attenuating oxidative damage.
