ABSTRACT
Prostate cancer is one of the malignant tumors with high incidence. Although most patients with prostate cancer respond well to standard treatment, they often have a poor prognosis once they develop hormone resistance. Radionuclide targeted therapy is an important method to treat malignant tumors after surgery and chemo-radiotherapy. New radioligand therapy (RLT), represented by 177Lu-prostate specific membrane antigen (PSMA)-RLT, effectively solves the problem of poor efficacy in advanced hormone-resistant prostate cancer, and has been widely recognized in the world. In this paper, the clinical practice of 177Lu-PSMA-RLT in the treatment of prostate cancer and its common adverse reactions are described in order to better understand and master its methods and lay the foundation for better clinical application and follow-up research.
ABSTRACT
Objective To investigate the correlations between the soluble form of B7-H3 ( sB7-H3) and the cytokines of IL-17 and IL-8 in serum samples from patients with primary hepatocellular carcino-ma ( HCC) and to evaluate their clinical values for early diagnosis of HCC.Methods Serum samples were collected from 63 patients with HCC and 50 healthy subjects.The expression of sB7-H3, IL-17 and IL-8 in serum samples were detected by ELISA.Receiver operating characteristic ( ROC) curve was generated to an-alyze the diagnostic values of sB7-H3, IL-17 and IL-8 for hepatoma.The logistic regression model was used to predict the probability of hepatoma by using sB7-H3, IL-17 and IL-8 in combination.Results The levels of sB7-H3, IL-17 and IL-8 in serum samples collected from the patients with HCC were significantly higher than those from healthy subjects.A positive correlation was found between the levels of sB7-H3 and IL-17 in serum samples from patients with HCC.No correlation was found between sB7-H3 and IL-8.A negative cor-relation was found between the levels of IL-17 and IL-8 in serum samples from patients with HCC.ROC curve analysis showed that the area under the curve (AUC) of sB7-H3, IL-17 and IL-8 were 0.832, 0.657 and 0.953, respectively, indicating the statistical significance of them for the diagnosis of HCC.The logistic regression showed that the AUC, diagnostic sensitivity and specificity of the regression model PRE in the pre-diction of HCC were 0.960, 91.30% and 94.29%, respectively, which was much better than using the three indicators alone.Conclusion The levels of sB7-H3 were positively correlated to the levels of IL-17 in serum samples from patient with HCC.The logistic regression model of combination of sB7-H3, IL-17 and IL-8 obtained in this study could be used for early clinical diagnosis of HCC in the future.
ABSTRACT
Objective To observe the expression level of inhibitor of differentiation 2 (Id‐2) and matrix metalloproteinases‐9 (MMP‐9) in rectal cancer ,analysis the correlation of the expression level of them ,to study the relationship between the expression level of them and the clinical pathology indicators of rectal cancer .Methods Rectal cancer tissues and normal tissue adjacent to rec‐tal cancer were obtained from the rectal cancer resection of 56 patients with rectal cancer ,using immunohistochemical method to ob‐serve the expression level of Id‐2 and MMP‐9 in normal tissue adjacent to rectal cancer and rectal cancer and Spearman correlation test to detect the correlation between the expression level of Id‐2 and MMP‐9 ;then we analyzed the relationships between the ex‐pression level of Id‐2 and MMP‐9 and the index of rectal cancer clinical pathology .Results The positive expression rate of Id‐2 in the in rectal cancer tissues is more higher than that of normal tissue of adjacent to rectal cancer (73 .21% vs .48 .21% ,P0 .05) .Conclusion There is a close relationship between the expression levels of Id‐2 and MMP‐9 in rectal cancer and the occurrence and development of rectal cancer .Rectal cancer with the higher Id‐2 expression level may be the ways to achieve tumor invasion and metastasis through MMP‐9 as a facilitator .
ABSTRACT
Objective To explore the effect of berberine hydrochloride on serum HIF-1α,Caspase -3 levels in patients with acute cerebral infarction with a multicenter study.Methods 126 patients with acute cerebral infarction from January 2012 to January 2014 were selected in the Affiliated Hospital of Hebei Engineering University,the First Hospital of Handan City,Handan Central Hospital were divided into experimental groups and control group using random number table.Control group had 63 cases,were given 80 mg ozagrel sodium injection intravenously,twice a day,and 800 mg calf blood protein injection intravenously,once per day on the basis of conventional treatment;at the same time,100 mg of oral aspirin tablets were taken,once per night,7 days for a course of treatment.Experimental group were given berberine hydrochloride on the basis of conventional treatment,0.7 g orally,three times a day,7 days for a course of treatment.After a course of treatment,serum HIF-1α,Caspase-3 levels in patients with acute cerebral infarction were observed before and after treatment.Results Serum HIF-1αlevels in two groups were reduced after treatment,and its level in experimental group[(733.49 ±225.01)ng/mL]was lower than that in control group [(975.32 ±311.35)ng/mL],the difference was statistically significant (P<0.05 ).Serum Caspase-3 levels in two groups after treatment were decreased,and its level in experimental group [(1 1.88 ±2.66 )ng/mL]was lower than the control group [(12.51 ±3.77)ng/mL],the difference was statistically significant (P <0.05).Conclusion Berberine hydrochloride could improve the serum HIF-1α,Caspase-3 levels in patients with acute cerebral infarction,reduce the fatality rate,and could be actively used in the recovery of patients with acute cerebral infarction treatment.
