Chinese Journal of Clinical Oncology 2014;(22):1450-1453
Objective:To retrospectively evaluate the prognostic risk factors of patients with gallbladder carcinoma and the effect of normal prognostic nutrition index (PNI) on the survival. Methods:We retrospectively analyzed 63 patients with gallbladder carcino-ma treated in our hospital between January 2008 and December 2012. The independent prognostic factors of the patients were calculat-ed by the Cox proportional hazards model. The benefit of normal PNI status on the prognosis was further explored in the patients using survival analysis. Results:Lymph node metastasis, PNI≤50, squamous carcinoma, liver invasion and choledoch invasion were the risk factors of overall survival (OS) in the univariate analysis, while only lymph node metastasis (HR=4.495, 95%CI 2.380~8.488, P<0.001) and PNI(HR=0.195, 95%CI 0.098~0.389, P<0.001) were the dependent influential factors of the prognosis and OS in the multi-variate analysis. The effect of PNI on OS was even more statistically significant different in the younger patients (≤65y) than in the el-der (>65y) (younger group:P=0.011;elder group:P=0.078). Conclusion:The gallbladder carcinoma patients with normal PNI status (>50) have better OS compared to the patients with PNI≤50, with statistical differences between the two. And it is more significant in the patients of the younger group (≤65y), comparing with the elder group. PNI could be taken as a potential prognostic evaluation factor for the gallbladder carcinoma patients and can provide a more comprehensive evaluation of patients' conditions to clinician.

OBJECTIVE To investigate the distribution features and clinical significance of allergens in patients with chronic rhinosinusitis(CRS). METHODS A retrospective analysis was performed in 136 cases of CRS. Allergen features were compared in the two subtypes of CRS: chronic rhinosinusitis with nasal polyps(CRSwNP) and chronic rhinosinusitis without nasal polyps(CRSsNP). Differences of allergens features of CRS were analyzed, and they were compared to the allergens of 36 patients with allergic rhinitis(AR). RESULTS The total allergen positive rate in CRS was 48.5%. The allergen positive rate, distribution proportion of inhaled and food allergens, distribution proportion of allergens subsets, distribution proportion of single and multiple allergens between two subtypes of CRS had no significant difference(P >0.05). The major allergens of CRS were single inhaled allergens(84.8%). Some CRS patients were allergic to food allergen(9.1%). The minority allergens of CRS were a mixture of inhaled and food allergens(6.1%). Compared to AR, the distribution proportion of inhaled and food allergens(χ2=14.801, P =0.001), the distribution proportion of allergens subsets(χ2=12.951, P=0.005), and the distribution proportion of single and multiple allergens(χ2=9.067, P=0.003) had significant difference. CONCLUSION The allergen positive rate of CRS is much higher than the prevalence of allergic diseases in general population, suggesting that allergic factors may be closely correlated to the pathogenesis of CRS. The clinical features of allergens are similar in the two subtypes of CRS, while there are significant differences in allergen distribution between CRS and AR patients. The detection of allergens may be helpful in prevention and treatment of CRS.

AIM: To study the effect and mechanism of chlorophyllin (CHL) inhibiting HT29 cells. METHODS: IC 50 value and growth curve of HT29 cells were detected with MTT method. Apoptosis was detected with Wright-Giemsa staining, FCM and DNA electrophoresis. Telomerase was detected by PCR-ELISA, and protein and mRNA expression of COX-2 gene were detected through RT-PCR and Western blot. RESULTS: CHL inhibited the growth of HT29 in a dose-dependent manner. CHL blocked HT29 cells in G 1 phase but did not induce apoptosis. Different concentration of CHL inhibits the expression of telomerase and COX-2 in HT29 cells. CONCLUSION: CHL inhibits the growth of HT29 cells by inhibiting the expression of telomerase and COX-2 and blocking cells in G 1 phase. [

Objective To compare the safety and efficacy of intravenous thrombolysis for patients with acute cerebral infarction in a second-grand class-A hospital and a third-grand class-A hospital. Methods Twenty-one consecutive patients with cerebral infarction treated with alteplase for intravenous thrombolysis were enrolled in a second-grand class-A hospital (Fengtai Hospital,Beijing)prospectively from January 2012 to December 2013 as the study group,and 65 patients in a third-grand class-A teaching hospital (Xuanwu Hospital,Capital Medical University,Beijing)admitted at the same period for intravenous thrombolysis were used as a control group. The differences of efficacy and safety of intravenous thrombolysis in patients of both groups were compared. The primary outcome measures were Barthel Index (BI)at day14 after onset and the modified Rankin Scale (mRS)scores at discharge. The main safety indicator was the incidence of serious adverse events (SAEs)after thrombolysis (symptomatic intracranial hemorrhage and death). Results (1 )In the primary outcome measures,the proportions of mRS≤2 at discharge in the study group and the control group were 71. 4%(n=15)and 58. 5%(n=38)respectively. At day 14 after thrombolysis,the proportions of BI ≥60 were 61. 9%(n=13)and 64. 6%(n=42)respectively. There were no significant differences between the two groups (P>0. 05). (2)The incidences of the primary serious adverse events were 4. 8%(n=1)and 6. 2%(n=4). There was no significant difference (P>0. 05). Other secondary outcome measures,such as the early reperfusion rate,recanalization rate,and the proportion of neurological improvement at day 14 after thrombolysis and the overall incidence of cerebral hemorrhage had no significant differences. The case referral proportion (9. 5%,n=2)of the study group had a trend of lowering than the control group (27. 7%,n=18)P=0. 09. (3)The out-hospital time delay, in-hospital time delay,and overall time delay of the study group were less than those of the control group, and the mean time was 75 ± 33 vs. 102 ± 50 min,and 72 ± 41 vs. 111 ± 38 min,147 ± 41 vs. 212 ± 47 min. There were significant differences (P<0. 01). Conclusion The second-grand hospital selected by our study can relatively safely and effectively perform intravenous thrombolysis for acute cerebral infarction with alteplase. Moreover,the intravenous thrombolysis of the second-grand hospitals may reduce the case referral ratio and visiting time.
