Objective:To evaluate the efficacy and safety of docetaxel+ prednisone in the treatment of castrated resistant prostate cancer in patients over 75 years old.Methods:In this study, 118 metastatic castration resistant prostate cancer (mCRPC) patients over 60 years old treated in Beijing Hospital from February 2013 to December 2019 were retrospectively analyzed. The median age of the patients was 72 (65, 77)years, ECOG scores ≤2. All 118 cases had bone metastasis, 5 cases had visceral metastasis. A total of 40 patients chose docetaxel as the first-line treatment of mCRPC, and the remaining 78 patients chose docetaxel as second-line or third-line treatment. The study included 53 patients >75 years old and 65 patients aged 60-75 years. The age of patients in the two groups were 67 (63, 71) years old and 78 (76, 83) years old, the difference was statistically significant ( P<0.05). Among them, there were 24 cases with Gleason score ≤7 and 41 cases with Gleason score >7 in 60-75 years old group, and 30 cases with Gleason score ≤7 and 23 cases with Gleason score >7 in the group of >75 years old, with significant difference between the two groups ( P = 0.034). Sixty-one patients received endocrine therapy and 4 received orchiectomy in the 60-75 years old group; 43 patients received endocrine therapy and 10 received orchiectomy in the group of >75 years old, the difference was statistically significant ( P=0.035). There were 37 cases with ECOG 0 score, 25 cases with 1 scores and 3 cases with 2 scores in the group of 60-75 years old; there were 5 cases with ECOG 0 score, 38 cases with 1 score and 10 cases with 2 score in the group of >75 years old, with significant difference between the two groups ( P<0.05). There was no significant difference in PSA level[ 90 (35.5, 258) ng/ml vs. 115 (60, 296) ng/ml], G8 scale score [(14.3±2.1 vs. 13.6±1.1)], Mini-Cog score[3(2, 3) vs. 3(1, 3)], and visceral metastasis [2 cases (3.1%) vs. 3 cases (5.7%)]( P>0.05). The efficacy and safety of docetaxel in the two groups were further observed. Results:The median follow-up time was 21.5 (6, 62) months. There was no significant difference in chemotherapy cycle [(6.1±1.3) vs. (6.8±1.7)] and chemotherapy dose [(70.3±4.3) mg/m 2 vs. (66.3±5.2) mg/m 2] between the 60-75 years old group and the >75 year old group ( P> 0.05). The PSA response rate [72.3%(47/65)vs.66.0%(35/53)], pain relief rate [45.0% (9/20) vs. 54.5% (6/11)], and median progression-free survival[6.1 (1.4, 11.2) months vs. 5.9 (2.0, 12.0) months] had no statistical significance ( P>0.05). There were no deaths in the two groups during chemotherapy. The median overall survival(OS) of patients aged 60-75 years and those >75 years old who received docetaxel as first-line treatment were 26.5 (16.1, 31.3) months and 24.8 (17.5, 28.4) months, respectively ( P=0.223). The median OS of the two groups were 17.3 (13.2, 20.5) months and 15.4 (12.3, 20.0) months with docetaxel treatment as second or third line treatment ( P=0.331). There were 3 cases (4.6%) and 5 cases (9.4%) of grade 3 adverse reactions in 60-75 years group and >75 years old group, respectively. Grade 3 leukopenia occurred in 1 case time (1.5%) and 2 cases (3.8%) respectively. Grade 3 neutropenia fever occurred in 1 case time in both groups. There was no significant difference in the incidence of above complications between the two groups ( P > 0.05). Conclusions:The efficacy and safety of docetaxel + prednisone chemotherapy for mCRPC patients >75 years old were similar to those of 60-75 years old. Age should not be the absolute contraindication of docetaxel for prostate cancer chemotherapy.

OBJECTIVETo analyze the relationship between the pulse pressure (PP) and atherosclerotic renal artery stenosis (ARAS) in middle-age and eldery paients with hyperensio, so as to provide the basis for the diagnosis and treatment of ARAS.

METHODSWe tetro spectively analyzed the data of 257 patients with hypertension undergoing renal arteriography at General Hospital of PLA between 2009 and 2014. Their mean age was (64.09 +/- 7.81) years. According the results of arteriography, they were divided into two groups: ARAS group (n = 145), and non-ARAS group (n = 112). Their PP and multinomial clinical indexes with ARAS were statistically analyzed.

RESULTSSingle factor correlation and Logisitic analysis showed that age, PP, serum creatinine (SCr) levels, and new onset of hypertension after 50 years of age were strongly positively related to ARAS. The age and PP and SCr was a team of continuous variable.

CONCLUSIONPP was the first new risk factor of ARAS in middile-aged and elderly patients with hypertension. It is suggested that PP may be a early predictive indicator and a new therapeutic target for ARAS.

Objective To evaluate the relationship between changes in B-type natriuretic peptide(BNP) and cardiac troponin I(cTnI)levels and prognosis of critically ill patients with sepsis. Methods This study retrospectively reviewed the clinical data of 75 patients with severe sepsis and septic shock admitted into Emergency Intensive Care Unit(EICU)of the First Affiliated Hospital of Wenzhou Medical University in Zhejiang Province. According to the severity of the cases,they were divided into two groups:severe sepsis group(34 cases)and septic shock group(41 cases),and based on the difference in prognosis,they were divide into survivor group(32 cases) and non-survivor group(43 cases). Electrocardiogram(ECG)was performed within 24 hours after admission in all the patients. Acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score and biochemical markers showing organ dysfunctions as BNP, cTnI, creatine kinase (CK), creatine kinase MB mass(CK-MB), and lactate were compared between severe sepsis and septic shock groups and between survivor and non-survivor groups. Results The septic shock group had significantly higher baseline BNP,cTnI,lactate and APACHE Ⅱscore and mortality rate than those in severe sepsis group〔BNP(μg/L):1.90(1.08,2.79)vs. 0.41(0.31,0.75),cTnI (μg/L):1.15(0.92,1.28)vs. 0.58(0.40,0.79),lactate(mmol/L):6.63±3.72 vs. 3.28±1.66,APACHEⅡscore:26.00(24.00,28.00)vs. 21.50(20.00,29.25),mortality rate:70.73%vs. 41.18%,P<0.05 or P<0.01〕. Compared with survivor group,the ages of non-survivor group were older with more males and higher BNP,cTnI,lactate and APACHEⅡscore〔males(cases):30 vs. 13,age(years old):66.49±14.97 vs. 58.19±17.05,BNP:1.60(0.62, 2.51)vs. 0.57(0.37,1.79),lactate:4.10(3.00,9.00)vs. 3.10(2.13,4.18),cTnI:1.02±0.49 vs. 0.62±0.37, APACHE Ⅱ score:28.00(25.00,30.00)vs. 21.00(20.00,25.75),P<0.05 or P<0.01〕. However,there were no statistically significant differences in the levels of CK and CK-MB between the above compared groups(both P>0.05). The patients' ECGs had no obvious changes. Conclusions High plasma BNP and cTnI levels in patients with sepsis may suggest myocardial damage and relatively bad prognosis. The examination of BNP and cTnI levels may help clinicians to early detect the high-risk patients with septic cardiac dysfunction and assess their prognoses.

Objective: Testicular mixed germ cell tumor is mixed with embryonal carcinoma, choriocarcinoma, yolk sac tumor, teratoma, seminoma and other two or more components of the testicular tumor, the clinical is relatively rare and high degree of malignancy, this article will summarize its clinical features and optimize its treatment.Methods: A retrospective analysis of the clinical data of 22 patients with testicular tumor mixed germ cell in Peking University Third Hospital from May 1994 to November 2016 was conducted using a combination of statistical analysis and discussion of the relevant literature.Results: The mean age of the 22 patients was (30.8±10.4) years and the rate of cryptorchidism was 13.6%.The maximum diameter of the tumor was (5.1±2.7) cm.The pathological results suggested that 12 cases (54.5%) contained two different germ cell tumor components, 7 cases (31.8%) contained 3 different tumor components, 2 cases (9.2%) contained 4 different tumor components, and 1 case (4.5%) contained 5 different tumor components.Tumor constituent analysis included yolk sac tumors(16 cases, 72.7%), mature teratoma (7 cases, 31.8%), immature teratoma (5 cases, 22.7%), embryonal carcinoma (17 cases, 77.3%) , choriocarcinoma (4 cases, 18.1%) and seminoma (6 cases, 27.3%).American Joint Committee of Cancer tumor staging indicated 19 cases of stage Ⅰ a tumor, 2 cases of stage Ⅱa tumor and 1 case of stage Ⅲa tumor.The mean values of human chorionic gonadotropin, alpha-fetoprotein and lactate dehydrogenase were 414.50 MIU/mL, 242.95 μg/L, 196.95 U/L (preoperative) and 17.20 MIU /mL, 90.20 μg/L, 183.70 U/L (postoperative within a year), and the comparison of the P values between the preoperative and the postoperative within a year were 0.079, 0.043 and 0.624.Fourteen patients underwent retroperitoneal lymph nodes dissection.Most patients lived with long-term survival (94.4%) after operation.Conclusion: Comprehensive treatment of radical orchiectomy with retroperitoneal lymphadenectomy combined with necessary radiotherapy or chemotherapy might help to control the tumor and achieve long-term survival for most patients with testicular mixed germ cell tumor.

Objective:To investigate the effect of persimmon leaf extract (PLE) on HEK293-APPswe transgenic cells (20E2).Methods:To determine whether the 20E2 cells model was successfully established,the level of Aβ1-40 in SH-SY5Y was detected and 20E2 cells(HEK293 cells stably expressing Swedish mutant APP)cultured in vivo by ELISA kit,and the expression of APP protein level was detected by Western blot.Cell viability was assayed by CCK-8 method and then selected the best concentration.Set groups:SH-SY5Y as normal control group (NC group),20E2 as model group (20E2 group),treating with PLE as treating group (20E2+PLE group).Reactive oxygen species (ROS) levels of each group were detected with DCFH-DA fluorescent probe.The extracellular level of Aβ1-42 were detected by ELISA kit.Cytoplasmic Nrf2,Nuclear Nri2,Whole-cell HO-1 were detected by Western blot.Results:Compared with model group,the expressions of ROS,Aβ1-42 were down-regulated and the Nuclear Nrf2 and Whole-cell HO-1 were up-regulated in 20E2+PLE group.Conclusion:PLE can reduce the level of oxidative stress of model group effectively,it possibly reduce the aggregation of Aβ1-42 and prevent oxidizing via activating Nrf2/HO-1 pathway.
