Objective To observe the clinical efficacy ofZhibai Dihuang Decoction combined with endocrine therapy for kidney-yin deficiency type of advanced prostate cancer and its influence on patient symptoms of hot flashes.Methods Totally 72 cases of advanced prostate cancer patients were randomly divided into the combined group (36 cases) and the control group (36 cases). Patients in the control group were treated with endocrine therapy, while patients in the combined group were additionally treated byZhibai Dihuang Decoction. After 12 weeks of treatment, serum prostate specific antigen (PSA), the international prostate symptom score (I-PSS), the clinical symptoms score, the number of cases of hot flashes and safety index before and after treatment were observed. Results In the course of treatment, the control group and the combined group each had 1 case lost to follow up. PSA and I-PSS in the two groups significantly decreased after treatment (P<0.01). The total efficiency rate of TCM syndrome was 94.3% (33/35) in the combined group, while it was 57.1% (20/35) in the control group, with significant difference (P<0.01). After treatment, the incidence of hot flushes was reduced after treatment in the combined group, but the control group increased, with significant difference (P<0.01). No adverse reaction was found in the two groups.ConclusionZhibai Dihuang Decoction combined with endocrine therapy is more effective than endocrine therapy alone, which can reduce the symptoms of hot flashes.

Objective To assess the effect and safety of lanthanum carbonate vs conventional phosphate binders for hyperphosphatemia in patients undergoing maintenance hemodialysis.Methods According to the collaborative search strategy,MEDLINE (1996 to 2012.12),EBCO (1996 to 2012.12),the clinical control test database of Cochrane Library and Chinese Wanfang database (1996to 2012.12) were searched.Related literature,whether Published or not and meeting summary included,were searched by hand.Quality assessment and data extraction were conducted by two independent investigators.Meta-analysis was conducted by RevMan 5.0.The following outcomes were assessed:serum phosphorus levels,serum iPTH levels,serum calcium levels and adverse events.Results were expressed as OR with 95％ confidence interval for dichotomous outcomes and WMD with 95％ confidence interval for continuous outcomes.Results A total of 10 reports were identified which met the inclusion criteria.The meta-analysis showed that the efficacy of treating hyperparathyroidism in hemodialysis patients was similar between lanthanum carbonate and conventional phosphate binders (WMD =-0.06,95％ CI-0.27 to 0.15,P =0.57) and the incidences of discontinuing due to adverse events were also similar.However,there were fewer hypercalcemic episodes and lower serum calcium levels in the lanthanum carbonate group compared to calcium-based phosphorus binders group.Conclusion Lanthanum carbonate is effective and well tolerated in treating hyperphosphatemia in hemodialysis patients with fewer hypercalcemia and lower serum calcium levels compared to calciumbased phosphate binders.

To explore the expressional information of PIWIL4 in human ovarian cancer, semi-quantitative reverse transcription polymerase chain reaction(semi-qRT-PCR) was used to detect the mRNA expression level of PIWIL1, PIWIL2, PIWIL3 and PIWIL4 in human ovarian clear cell carcinoma ES-2 cells.Meanwhile, in human ovarian cancer and adjacent normal tissues, the mRNA expression of PIWIL4 was determined.Then, PIWIL4-siRNA, which was designed to target PIWIL4 and chemical synthesized, was transfected into ES-2 cells with lipofectamine.MTT assay and clone formation assay were used to investigate the effects of PIWIL4-siRNA on the cell growth activity and proliferation capacity of ES-2 cells.Experimental results showed that the mRNA expression level of PIWIL4 was the highest compared to PIWIL1, PIWIL2 and PIWIL3 in ES-2 cells(P

ObjectiveTo investigate the relationship between liver stiffness and hepatocellular carcinoma (HCC) risk in chronic heptatitis B patients with negative α-fetoprotein (AFP) tests. MethodsFrom September 2012 to August 2014, this study enrolled a total of 82 HBV-relative native HCC patients as the case group. During the same period, a total of 253 chronic hepatitis B patients were also include in this study as the control group. These 253 patients were followed up for six months. All of the two groups were AFP-negative. Liver stiffness was measured in all patients by transient elastography device Fibroscan?. Logistic regression was applied to assess the risk of HCC incidence, and stratum-specific likelihood ratios (SSLR) was calculated.ResultsThe age, liver stiffness measurements and plasma albumin of patients in case group were 53 years old (44-61), 12.00 kPa (7.50-20.75), 43.14 g/L (39.50-46.75) respectively. The age, liver stiffness measurements and plasma albumin of patients in control group were 45 years old (38-56), 8.40 kPa (5.40-13.50), 46.40 g/L (43.75-48.50) respectively. The variables were compared between two groups with unpaired studentt test, and the results were statistically significant (t=4.33, 3.56,
-4.48,P=0.00, 0.00, 0.00). The patients in case group were older, and had higher liver stiffness measurements and lower plasma albumin than that of the patients in control group. Logistic regression analysis showed that HCC incidence was associated with age,male-gender and liver stiffness, and the odds ratios (OR) was 1.053, 2.432, 6.803 respectively. When liver stiffness was<10 kPa, 10.1-15 kPa, 15.1-25 kPa,>25 kPa, SSLR for HCC presence was 0.67, 1.02,1.44, 3.98 respectively.ConclusionsLiver stiffness measured by transient elastography is useful in predicting the risk of HCC incidence in AFP-negative chronic heptatitis B patients. Clinicians needed to carry out close follow-up and appropriate intervention for these patients.

The PET tracer 5-([11C]methyloxy)-L-tryptophan (5-(11)CMTP) was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure in order to develop specific tumor probe. The biodistribution and microPET imaging of 5-(11)CMTP were executed. The results unveiled that the overall radiochemical yield with no decay correction was (14.6 ±7.2) %, the radiochemical purity was more than 95% and high uptake and long retention time of 5-(11)CMTP in liver, kidney and blood were observed but low uptake in brain and muscle were found, furthermore, high uptake of 5-(11)CMTP in tumor tissue was observed. It seems that 5-(11)CMTP will be a potential amino acid tracer for tumors imaging with PET.

Objective To investigate the expression of apolipoprotein M in rats after renal transplantation and its role and action mechanism in acute rejection (AR).Methods The kidney transplantation model in rats were established.Male SD and Wistar rats were used as donors,and Wistar rats as recipients.Three groups were designated:control group (syngeneic transplantation,n =24,recipients were treated with normal saline i.p.); AR group (allogeneic transplantation,n =24,recipients were treated with normal saline i.p.); PDTC group [allogeneic transplantation,n =24,recipients were treated with NF-κB inhibitor-pyrrolidine dithiocarbamat (PDTC) i.p.].The renal grafts were drawn at day 1,3,5 and 7 post-transplantation,and the expression levels of NF-κB P65 and apoM protein were detected by using Western blotting,and those of apoM,perforin and granzyme B mRNA were by using real-time PCR.The correlation of apoM and NF-κB,apoM and perforin,and apoM and granzyme B was respectively analyzed.Results As compared with control group,the expression levels of apoM,perforin and granzyme B mRNA in AR and PDTC groups were dramatically up-regulated at each time point (P＜0.01),and those in PDTC group were significantly lower than those in AR group (P＜0.01).The expression levels of apoM and NF-κB protein in AR group were both distinctly higher than those in control group (P＜0.01),and those in PDTC group were markedly lower than those in AR group (P＜0.01).A significantly positive correlation was found between the expression of apoM and NF-κB protein (r =0.469,P＜0.05).And the expression of apoM mRNA was positively correlated to perforin and granzyme B mRNA (r =0.731,P＜0.01 ; r =0.514,P＜0.05).Conclusion The expression of apoM is obviously up-regulated in renal grafts of rats,which may take part in the pathogenesis of AR via NF-κB.

Objective: To observe the effects of follistatin (FST)on the skeletal muscle wasting of cancer cachexia mice and the expressions of Mstn, LncRNA-MALAT1 and Caspase-3, and to elucidate its associated molecular mechanisms.Methods:Thirty-two BALB/c mices were randomly assigned into:healthy control (HC) group,FST prevention (FP)group,FST treatment (FT)group and cancer cachexia (CC)group.The murine colon adenocarcinoma CT26 cells were inoculated subcutaneously into the mices in FP, FT and CC groups to establish the cancer cachexia models. The body weight, spontaneous activity and tumor growth were daily monitored.The mice in FP and FT groups were administrated with FST intraperitoneally on day 6 and 12 after inoculation.The samples were collected on day 20.The tumor and gastrocnemius weights of the mice were detected. The biochemical metabolism indexes and myofiber cross-sectional area of gastrocnemius tissue were detected.The mRNA expression levels of Mstn,Caspase-3 and LncRNA-MALAT1 were examined by Real-time PCR.The protein expression levels of Mstn and Caspase-3 were measured by Western blotting method. Results:Compared with CC group,the body weights,spontaneous activities,gastrocnemius weights and myofiber cross-sectional areas were increased (P <0.05);the serum levels of glucose,total protein and albumin of the mice in FP and FT groups were increased (P <0.05).The protein and mRNA expression levels of Mstn and Caspase-3 in gastrocnemius of the mice in CC group were significantly higher and the expression level of LncRNA-MALAT1 was significantly lower than those in HC group (P < 0.05).The mRNA and protein expression levels of Mstn and Caspase-3 in FP and FT groups were reduced and the expression level of LncRNA-MALAT1 was increased compared with CC group (P < 0.05).The prevention effect in FP group is better than FT group (P < 0.05). Conclusion:FST may alleviate the muscle wasting of the mice with cancer cachexia by inhibiting the expression of Mstn,thus upregulating the expression of LncRNA-MALAT1 which in turn to suppress the expression of Caspase-3.

Objective To study the effect of corrected TIMI frame count (CTFC) of infarction related artery on systolic function of infarct area of myocardium after primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods One hundred and six patients with AMI having undergone successful PCI in Cangzhou Central Hospital were selected, and they were divided into two groups (each, 53 cases). The standard of fast or slow flow was in accord to the CTFC of infarction related artery (IRA) measured soon after successful PCI. The patients with greater value of CTFC were enrolled in the slow flow group, while the patients with smaller such value were assigned in the fast flow group. At 6, 12, 24 and 48 hours after PCI, the venous plasma MB isoenzyme of creatine kinase (CK-MB) level was measured. And at 1 week, 1 month and 3 months after PCI, the left ventricular ejection fraction (LVEF) was measured by cardiac ultrasound, and the levels of radial strain (RS) and longitudinal strain (LS) of the infarct area were measured via speckle tracking imaging (STI). The differences in CTFC, CK-MB, RS and LS between the two groups were analyzed, and the correlations between the strains and CTFC, CK-MB were analyzed by Pearson linear correlation method. Results After successful PCI, the CK-MB of fast flow group was higher than that of the slow flow group at 6 hours. However, the CK-MB of slow flow group was higher than that of the fast flow group after 12 hours, appearing separate phenomenon, and the statistical significance occurred beginning from 24 hours after PCI (U/L, 24 hours:98.43±11.65 vs. 86.43±18.97, 48 hours:51.09±8.94 vs. 49.80±6.92, both P<0.05). CTFC in fast flow group was significantly lower than that of slow flow group (frame: 22.69±4.83 vs. 26.14±5.67, P < 0.01). After 3 months of follow-up, LVEF in fast flow group was higher than that of the slow flow group, but the difference had no significance (P > 0.05). RS and LS in fast flow group were higher than those in slow flow group, and the statistically significant difference appeared from 1 month after PCI (1 month RS:29.74±6.66 vs. 26.86±5.61, LS:-16.37±3.91 vs. -15.27±3.22, 3 months RS: 30.03±6.31 vs. 27.63±5.67, LS: -17.74±3.96 vs. -15.75±4.17, all P < 0.05). Pearson linear correlation showed:the strains (both RS and LS) and CK-MB had no significant relation (both P>0.05). Both RS and LS at 1 week, 1 month and 3 months were of significantly positive correlation with CTFC of each group (fast flow group:r value of CTFC and RS was respectively-0.526,-0.515,-0.532, r value of CTFC and LS was respectively-0.532,-0.541,-0.572;slow flow group:r value of CTFC and RS was respectively-0.691,-0.685,-0.702, r value of CTFC and LS was respectively-0.621,-0.584,-0.605, all P<0.01). Conclusion CTFC has some relationship with the recovery of the systolic function in area of infarct myocardium after PCI, and can be regarded as an important index to predict the long-term prognosis in patients with AMI.
