Objective To discuss the artery effects of enhanced external counterpulsation for the progressive stroke patients.Methods Ninety-two progressive stroke patients who were treated in the Fourth People's Hospital of Shenzhen from August 2010 to February 2015 were selected and equally divided into the treatment group and the control group based on the random number table.The control group were received conventional therapy,and the treatment group were added treated with enhanced extemal counterpulsation therapy.Results All patients were successfully completed treatment,the C-reactive protein (CRP) and Endothelin-1 (ET-1) were presented decreased significantly after treatment (P< 0.05),and the C RP and ET-1 values in the treatment group were (2.09±2.11) mg/L,(13.98±6.30) mg/L,significantly lower than those of the control group((8.12±2.46) mg/L,(46.09± 11.02) mg/L;t =15.309,14.985;P<0.05).After treatment,the FMD and NMD values in the treatment group were significantly increased from (5.26±1.34)% to (11.93 ±2.13) %,and from (13.20±5.33)% to (22.98±8.34)%,in the control groupand were from (5.27±1.33)% to (8.10±1.43) %,and from (13.67±4.10)% to (16.09±5.12)% (t=16.934,21.787,8.443,12.345;P <0.05),and the value of FMD and NMD in treatment group were significantly higher than in the control group(t =7.982,9.113;P < 0.05).The cardio ankle vascular index (CAVI) and brachial ankle pulse wave velocity (baPWV) values in the treatment group were significantly reduced after treatment,the difference was significant (P<0.05),and compared with the control group the difference was also statistically significant (t =4.281,8.456;P< 0.05).Conclusion Enhanced external counterpulsation for the progressive stroke patients can effectively inhibit the expression of endothelin and inflammatory factors,improve endothelium-dependent relaxation of blood vessels,improve arterial elasticity,and thus play more effective treatment.

Objective To study the expressions of erythmpoietin(EPO)and its receptors(EPOR)in the injured brain tissue ofthe rats with traumatic brain injury(TBI).Methods A total of78 SD rats were randomly divided into three groups including control group(six rats),sham group(36rats) and fluid percussion injury group(36 rats).The rats were sacrificed at 6,24 hours,3,5,7 and 14days after TBI in the sham group and the fluid percussion injury group(six rats at each time point).Then,the injured brain tissues were removed for observation of the mRNA and protein expressions of EPO and EPOR by meaDiB of real-time PCR and Western blot. Results The expression of EPO was increased at 24 hours and reached the peak at day 3 after TBI.The hish expression level of EPO could maintain for two days or so.began to decrease at day 7 and recovered to normal at day 14 after Till.While the expression of EPOR reached the peak at 24 hours after TBI and maintained hish level at day14. Conclusions The expressions of EPO and EPOR show increase within 24 hours after TBI.In fact,the expressions of both factors are not in consistency,with more transient expression of EPO.

Objective To explore the danger of lead exposure in newborns who accepted the blood stored in blood bank for blood change treatment.Methods The lead level of blood was examined before and after blood change treatment for 37 neonates with hyperbilirubinemia who accepted 53 cases blood stored in blood bank during Jun.to Dec.2006.The level of blood lead was measured by graphite stove atom absorb spectrum method.Results The average lead level of 53 cases blood stored in blood bank was 101.02 ?g/L,which had attained the level of lead poisoning.There were 15 cases(28.5%) whose blood lead levels was very high(≥100 ?g/L),3 cases whose blood lead level ≥200 ?g/L.After blood change treatment,the percentage of the blood lead level ≥100 ?g/L rose from 2.9% to 19.0%.The average level of blood lead after blood change treatment was higher than before(P

The biochemical mechanism of degrading keratins by S.fradiae var S-221 was primarily studied.The compounds (Na_ 2 SO_ 4 , Na_ 2 SO_ 3 and sulfdryl acohol), which respecitively enhance specific activity of keratinase, activate keratinase intensively and mainly act on the disulfide bonds reductase in the keratinase, Na_ 2 SO_ 3 activates intensively both disulfide bonds reductase and polypeptide hydrolytase at 0.01 mol/L, whereas Na_ 2 S_ 2 O_ 3 , which acts on the disulfide bonds reductase, inhibits keratinase.On the condition that substrate, keratins exists, S.fradiae var S-221 is induced to produce exo-keratinase, which is a multiproteinase, containing disulfide bonds reductase, which is a key enzyme degrading keratins, then, with polypeptidic, hydrolytase, graduately hydrolyzates denatured keratins into polypeptides, oligopeptides and free amino acids, so that keratins have been decomposed completely.Sulfur in the keratins was transferred into sulfhydryl compounds, H_ 2 S and sulfates in the course of keratinolysine.

OBJECTIVE:
To observe the expression of aquaporin 4 (AQP4) in diffuse brain injury (DBI) of rats and to explore the corresponding effect of AQP4 for brain edema.
METHODS:
The rat model of DBI was established using Marmarou's impact-compression trauma model. Brain water content was measured by dry-wet weight method. Blood-brain barrier permeability was evaluated by Evans blue (EB) staining. Immunohistochemical method was used to observe the expression of AQP4.
RESULTS:
Brain water content increased after 3 h and peaked at 24 h after DBI. Brain EB content significantly increased and peaked at 12 h after DBI. The expression of AQP4 significantly increased after 3 h and peaked at 24 h after DBI, and the number of AQP4 positive astrocytes increased.
CONCLUSION
The increment of the permeability of blood-brain barrier and the expression of AQP4 may contribute to the development of brain edema in rat DBI. The change of AQP4 expression in astrocytes may also contribute to determine DBI.

OBJECTIVETo investigate the role of EPHA2 in regulating apoptosis, proliferation and vasculogenic mimicry of osteosarcoma cells, by gene silencing through RNA interference.
METHODSEPHA2-siRNA plasmids were achieved by gene cloning. The plasmids were transfected into human osteosarcoma cells (MG63). The expression level of EPHA2 protein was measured by Western blotting. The proliferation, apoptosis and vasculogenic mimicry features of osteosarcoma MG63cells were assessed by light microscopy, MTIP assay, flow cytometry, annexin V-FITC/PI and HE staining, respectively.
RESULTSThe EPHA2-siRNA plasmid was confirmed by DNA sequencing. After treatment with Sequence-specific siRNA targeted EPHA2, the protein level of the transfected group decreased significantly. As compared to non-siRNA transfected cells, the transfected group showed lower proliferation, higher and earlier apoptosis and less osteosarcoma-generated vasculogenic mimicry.
CONCLUSIONEPHA2 gene may be involoved in apoptosis and proliferation of osteosarcoma cells, and may be necessary for vasculogenic mimicry. Down-regulation of EPHA2 expression by sequence-specific siRNA may be considered as a new option in the treatment of EPHA2 over-expressing cancer including osteosarcoma in future.

OBJECTIVETo summarize the methods, safety and efficiency of surgical resection for hilar cholangiocarcinoma.
METHODSThe clinical and follow-up data of 48 patients with hilar cholangiocarcinoma underwent surgical resection from January 2003 to December 2007 were analyzed retrospectively. There were 26 male and 22 female, aged from 38 to 72 years old with a mean of 63.6 years old.
RESULTSPerioperative management including percutaneous transhepatic biliary drainage applied in 19 cases and portal vein embolization applied in 2 cases. Eight patients were treated with extrahepatic bile duct resection with or without parital hepatic segment II resection, 10 cases with perihilar hepatic resection (segment IVB, partial V, partial VIII, I), 28 cases with extended hemihepatectomy and 2 cases with central hepatic resection (segment IVB, V, VIII, I). R0 resection rate was 89.5% and the operative mortality was 2.1%. The 1-, 3- and 5-year survival rate were 93.5%, 51.8% and 36.5%, respectively. Patients undergoing extended hepatic resection survived significantly longer than those undergoing partial hepatic resection (P = 0.034).
CONCLUSIONSExtended hepatic resection for hilar cholangiocarcinoma offers good outcomes with an acceptable mortality rate.
