Objective To investigate the effects of penehyclidine hydrochloric(PHC)pretreatment on the expression of β-arrestin-2 in the lung tissue in sepsis-induced acute lung injury in mice.Methods Thirty female Ktmming mice,aged 6 weeks,weighing 18-20 g,were randomly divided into 3 groups(n =10 each):sham operation group(group S); sepsis group(group CLP)and penehyclidine hydrochloric pretreatment group(group PHC).Sepsis was induced by cecal ligation and puncture(CLP)in groups CLP and PHC.Penehyclidine hydrochloric 0.45 mg/kg was injected intraperitoneally at 1 h before CLP in group PHC.While the equal volume of normal saline was given instead of penehyclidine hydrochloric in groups S and CLP.At 12 h of CLP,the animals were sacrificed,and the lung tissues were removed for determination of MPO activity(by colorimetry),IL-6 content(by ELISA),β-arrestin-2 mRNA and protein expression(by RT-PCR and Western blot respectively).Blood samples and bronchoalveolar lavage fluid were collected to calculate pulmonary vascular permeability index(PV PI).Results Compared with group S,PVPI,IL-6 content and MPO activity were significantly increased,the expression of β-arrcstin-2 protein was significantly down-regulaled while the expression of β-arrestin-2 mRNA was up-regulated in group CLP,and PVPI,IL-6 content and MPO activity were significantly incrcased,the expression of β-arrestin-2 protein was significantly up-regulated,while the expression of β-arrestin-2 mRNA was down-regulated in group PHC(P < 0.05).Compared with group CLP,PVPI,IL-6 content,and MPO activity were significantly decreased,the expression of β-arrestin-2 protein was significantly up-regulated,while the expression of β-arrestin-2 mRNA was dow n-regulated in group PHC(P < 0.05).Conclusion PHC pretreatment can attenuate the lung injury induced by sepsis in mice through up-regulating the expression of β-arrestin-2 protein.

Objective To investigate the prognosis of local resection in patients with low rectal cancer, and assess surgical indications for this procedure. Methods One hundred and twenty-four patients with low rectal cancer from Jan 1975 to Dec 2006 were analyzed, the clinicopathologic features and surgical, outcome were examined as prognostic factors. Survival rate was estimated by Kaplan-Meier method and compared by Log-Rank test, prognostic factors were analyzed by multivariate COX proportional hazards model. Results The 5-year survival rate of 124 patients underwent local resection was 90.7 %(97/107), there were 4.8 %(6/124) patients with complications and 15.3 %(19/24) ones with local recurrence.The infiltration, vascular invasion, the size of tumor and the histological grade were significant prognostic factors of overall survival, but gender, age, the tumor site and the macroscopic type were not. Multivariate analysis indicated that the tumor infiltration were independent poor prognostic factor. Conclusion Local resection is suitable for Tis and T1 low rectal cancer, and those with high local recurrence factors should undergo radical resection. Strict follow-up and adjuvant therapy is necessary for local excision.

Objective To investigate the effects of penehyclidine hydrochloride (PHCD) pretreatment on β-arrestin-1 expression during sepsis-induced acute lung injury in mice.Methods Thirty female Kunming mice,weighing 18-20 g,were randomly divided into 3 groups (n =10 each):sham operation group (S group),sepsis group (CLP group) and PHCD group.Sepsis was induced by cecal ligation and puncture (CLP).In PHCD group,PHCD 0.45 mg/kg was injected intraperitoneally 1 h before CLP.The equal volume of normal saline was given instead in groups S and CLP.The mice were sacrificed at 12 h after CLP,bronchoalveolar lavage fluid (BALF) was collected for measurement of the total protein concentration,and the lungs were removed for determination of wet/dry lung weight ratio and expression of myosin light chain kinase (MLCK),vascular endothelial cadherin (VE-cad-herin) and β-arrestin-1 in lung tissues.The pathological changes of the lung were scored.Results Compared with group S,the lung injury score,wet/dry lung weight ratio and total protein concentration in BALF were significantly increased,MLCK expression was up-regulated and VE-cadherin expression was down-regulated in groups CLP and PHCD,β-arrestin-1 expression was down-regulated in group CLP and β-arrestin-1 expression was up-regulated in group PHCD (P < 0.05 or 0.01).The lung injury score,wet/dry lung weight ratio,total protein concentration in BALF,and MLCK expression were significantly lower,while the expression of VE-cadherin and β-arrestin-1 was higher in PHCD group than in CLP group (P < 0.05 or 0.01).Conclusion PHCD pretreatment can ameliorate acute lung injury through up-regulating β-arrestin-1 expression and reducing microvascular permeability in septic mice.

OBJECTIVE:
Dynamic observation of Epstein-Barr virus (EBV) DNA load before and after the treatment in patients with Nasopharyngeal carcinoma (NPC), predicting the incidence of distant metastasis and offering more personalised choice of therapies.
METHOD:
Fifty-four cases of patients with NPC were taken by fluorescence quantitative PCR assay of EBV DNA load before and after the treatment, all patients were followed up according to plan and carried out the progression-free survival (PFS) and overall survival (OS).
RESULT:
EBV DNA load in plasma of patients with NPC can partly reflect the clinical characteristics of patients; EBV DNA load in some patients with distant metastasis was higher than those patients with continuous remission when they were not started treatment (P < 0.05); For those patients whose EBV DNA copies were lower than 20,000 copies/mI before the treatment, the progression-free survival and overall survival rates were higher than those high expression patients, and the difference were statistically significant (PF < 0.01 and P < 0.05).
CONCLUSION
The EBV DNA load in the plasma of NPC patients can partly predict the occurrence of distant metastases before treatment.

Purpose To investigate the CT and CTA findings of intracranial hemanigoperiocytoma. Materials and Methods The CT and CTA data of 7 cases of pathologically confirmed intracranial hemanigoperiocytoma were retrospectively reviewed. Results All the 7 cases were extra-axial and supratentorial location. Six were lobulated and 1 were oval in shape. Three were iso-density to the parenchyma and 4 were inhomogeneous with clear margins. Five had perifocal edema. On contrast scan, all showed homogeneous or inhomogeneous enhancement. Five had dilated tortuous vessels and 4 were identified as feeding artery inside or around the tumors. Conclusion The CT findings of intracranial hemanigoperiocytoma are similar to meningioma but CTA is helpful for the differential diagnosis.
