Chinese Journal of Biochemical Pharmaceutics 2016;36(12):53-56
Objective To explore the effects of surgical castration and intermittent androgen blockade (IAB) in patients with advanced prostate cancer.Methods 115 cases of advanced prostate cancer were selected including 48 cases with drug castration receiving IAB and 67 cases with surgical castration.Before the treatment, 6 months and 1 years after the treatment, the quality of life of the two groups was investigated by the quality of life questionnaire (EORTC QLQ-C30 +QLQ-PR25).Results Compared with before treatment, the general health status of the patients in the drug castration group and the surgical castration group were significantly improved (P<0.01), the whole body and the local pain were relieved (P<0.01) and the micturition symptoms were controlled ( P<0.01 ).The overall quality of life of drug castration group and surgical castration group were significantly decreased (P<0.05), and the degree of sexual function was particularly affected (P<0.01), but the body function of patients in drug castration group restored to a certain extent in drug castration group after 1 year’s treatment(P<0.01), while the quality of life in patients of surgical castration did not reverse.Conclusion Both of surgical castration and androgen deprivation therapy can reduce the quality of life of patients with advanced prostate cancer, but the adverse effects of drug treatment on the quality of life can be recovered in treatment intermission.

Objective To investigate the effect of precondition with Toll-like receptor 4 monoclonal antibody (TLR4mAb) on lipopolysaccharide (LPS) -induced acute lung injury in mice.Methods A total of 45 male BALB/c mice were randomly divided into 3 groups:the control group ( group C),the sepsis group (group S) and the pretreatment group (group P).Mice in the group P and group S were injected intraperitoneally with LPS ( 10 mg/kg) to produce acute lung injury models.Mice in the group P was injected intraperitoneally with TLR4mAb (5 μg/g) 1 h before the injection of LPS.Expression of TLR4mRNA in lung tissue,expression of TNF-α and IL-6 in serum,water content of lung,and the pathomorphologic changes of lung were detected after 6 h,12 h and 24 h.One-way ANOVA was used for inter-group comparison and two-way ANOVA was used for intra-group comparison.Results Compared to group C,water content significantly increased at 12 h and 24 h in group S and group P; compared to group S,water content significantly decreased in group P at 12 h and 24 h.Compared to group C,the expression of IL-6 and TNF-α significantly increased in group S and group P at 6 h,12 h and 24 h; compared to group S,the expression of IL-6 and TNF-α significantly decreased at 6 h,12 h and 24 h in group P.Compared to group C,the expression of TLR4 mRNA increased significantly in group S and group P at 6 h,12 h and 24 h; compared to group S,the expression of TLR4 mRNA decreased significantly in group P at6 h,12 h and 24 h.Compared to group S,pathological damage of the lung was improved significantly in group P.Conclusions Precondition with TLR4mAb can attenuate LPS-induced acute lung injury,suppress the expression of inflammatory factors.Regulation of TLR4 pathway may be a promising therapeutic strategy for ALI.

Objective To explore the current status of social support and its influence factors among MSM in Chongqing .Meth‐ods The status of social support was measured by Social Support Rating Scale(SSRS) in 803 males who have sex with man (MSM) .Results Eight hundred and three MSM were selected as the subjects ,whose average overall scores of social support were 29 .240 ± 6 .228 .Increasing with the growth of the number of friends in gay circles ,MSM tended to obtain more social supports . SSRS score displayed that MSM with features like same gender sexual orientation ,infecting STDs ,only child and did not have regu‐lar homo sex partners got lower social support(P<0 .05) .Conclusion Their social support system should be improved .Therefore , the quality of life and social support will be improved ,thus to maintain their physical and mental health .

Objective: To explore therapeutic effect of statins on patients with type 2 diabetes mellitus (T2DM) complicated atherosclerotic cardiovascular diseases.Methods: Clinical data of 103 T2DM patients with atherosclerotic cardiovascular diseases, who were treated in our hospital from Oct 2013 to Dec 2015, were retrospectively studied.According to usage of statins or not, patients were divided into routine treatment group (n=50,didn't use statins) and statin group (n=53,received statins based on routine treatment), both groups were treated for one year.Blood lipid levels before and after treatment, and incidence of cardio-and cerebrovascular events during treatment were measured and compared between two groups.Results: Compared with before treatment, after treatment, there were significant reductions in levels of triglyceride (TG), total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), and significant rise in level of high density lipoprotein cholesterol (HDL-C) in statin group(P<0.01 all).Compared with routine treatment group after treatment, there were significant reductions in levels of TG [(2.13±0.37) mmol/L vs.(1.74±0.41) mmol/L], TC [(5.38±0.45) mmol/L vs.(4.34±0.73) mmol/L] and LDL-C [(3.63±0.72) mmol/L vs.(2.55±0.61) mmol/L], and significant rise in HDL-C level [(0.95±0.31)mmol/L vs.(1.34±0.35)mmol/L] in statin group, P<0.01 all.During one-year treatment, incidence rate of cardio-and cerebrovascular events in statin group was significantly lower than that of routine treatment group (18.18% vs.56.67%), P=0.002.Conclusion: Statins could effectively correct abnormal lipid metabolism and reduce risk of cardio-and cerebrovascular events in patients with type 2 diabetes mellitus complicated atherosclerosis cardiovascular diseases.

Objective To observe the impact of diabetes and stress hyperglycemia on thrombolytic effect and short-term prognosis in patients with acute cerebral infarction. Methods A total of 127 patients with acute cerebral infarction (≤4. 5 h) who received thrombolytic therapy with alteplase at General Hospital of Beijing Military Command from January 2012 to August 2013 were enrolled retrospectively. They were divided into three groups:Diabetes group (n=35),stress hyperglycemia group (n=49),and normal glucose group (n=43) according to whether they had a history of diabetes,random glucose on admission, and oral glucose tolerance test at day 7. At 24 h after thrombolysis,the National Institute of Health Stroke Scale (NIHSS) scores,recanalization rate,and the modified Rankin Scale (mRS) scores at day 90 were compared between the 2 groups. Results Before thrombolysis,the NIHSS scores of the diabetic group, stress hyperglycemia group,and normal glucose group were 14. 2 ± 5. 1,12. 8 ± 5. 6,and 13. 0 ± 4. 6,respectively (P>0.05);at 24 h after thrombolysis,they were 14.7 ±6.0,11.9 ±4.9,and 8.0 ±2.9,respectively (P<0.05);compared with before thrombolysis,the NIHSS scores of the diabetes group and the stress hyperglycemia group had no significant change (P>0. 05);the NIHSS score of the normal glucose group was lower than before thrombolysis. There was significant difference (P <0. 05). After thrombolysis,the patients with good recanalization were 54. 3% (n=19),57. 1% (n=28),and 67. 4% (n=29),respectively in the three groups;the hemorrhagic conversion rate was 14. 3% (n=5),6. 1% (n=3),and 2. 3% (n=1),respectively. There were no significant differences. At day 90 after thrombolysis,the mRS scores in the 3 groups showed that the good prognosis rate of the normal glucose group was 72. 1% (n=31);it was significantly higher than 51. 0% (n=25) of the stress hyperglycemia group and 29. 6% (n=10) of the diabetes group. There were significant differences (P<0. 05,P<0. 01). There was also significant difference between the stress hyperglycemia group and the diabetes group. Conclusion Diabetes and stress hyperglycemia have varying degrees of adverse effects on the efficacy and prognosis of the thrombolytic therapy for acute cerebral infarction.
