Objective To investigate the relationship between the variation of endothelial progenitor cells (EPC) number and cardiovascular diseases (CVD) in maintenance hemodialysis (MHD) patients ,and discuss the function of EPC in the progression of CVD in MHD. Methods One hundred and fifteen MHD patients over 18 years whose dialysis vintage was over six months from Department of Nephrology, Renji Hospital, Shanghai Jiao Tong University School of Medicine were enrolled. They were divided into CVD group and non ? CVD group by medical history, electrokardiographie (EKG), cardiac ultrasound, peripheral vascular imaging and cardiovascular imaging. Peripheral blood (5 ml) was collected for detecting EPC number by flow cytometry as CD34/CD133/vascular endothelial growth factor receptor 2 (VEGFR2) cells. The EPC number between CVD group and non?CVD group was compared. The relationship between the decrease of EPC number and CVD risks in MHD patients was analyzed by logistic regression analysis. In a three?year follow?up, the death and new CVD events of the two groups were compared in order to discuss the relationship between EPC number and adverse events. Results Among 115 MHD patients, the average age was 61.57 ± 12.76, male/female was 71/44, the average dialysis vintage was (86.24 ± 56.31) months, the average Kt/V was 1.69 ± 0.29 and average ultrafiltration volume was (2.48 ± 0.90) L. Forty?four patients in 115 (38.3%) were with concurrent CVD. The EPC number in CVD group was significantly lower than that in non CVD group (P=0.015). The CVD group had higher serum phosphate (P=0.013), higher glycosylated hemoglobin (P<0.001), but serum calcium, intact parathyroid hormone (iPTH) and other indicators had no significant difference between two groups. Multiple Logistic regression analysis showed that older age (OR=1.061), history of diabetes (OR=9.796), dialysis vintage (OR=1.015), serum phosphate (OR=3.766), decrease of EPC number (OR=0.909) were the independent impact factors of CVD events in MHD patients. There were 22 patients of the 115 MHD patients had encountered a new CVD event in a three?year follow?up between December 2012 and December 2015, 9 patients from the CVD group and 13 patients from the Non?CVD group, and there was no significant difference between two groups (P=0.776). Nine patients from the CVD group and 7 patients from the Non?CVD group died in the follow?up, and there was no significant difference (P=0.111). Seventy?one MHD patients from the non?CVD group were divided into two groups by the median of EPC number. There were 3 patients in the higher EPC number group encountered CVD events and 10 patients in the lower EPC number group encountered CVD events, which had significant difference (P=0.024). Conclusion The decrease of circulating EPC number may be related with CVD events in MHD patients. Even adjusted by age, sex, diabetes, dialysis vintage and serum phosphate, decreased EPC number is still the independent risk factor of CVD events in MHD patients. The decrease of EPC number in MHD patients may be used to predict the occurrence of cardiovascular events.

Objective Through observing the clinical effect and the changes of gastrointestinal hormones caused by the treatment of different moxibustion time of the superficial gastritis patients due to the spleen and stomach weakness,to investigate the regulation of the dose-effect relation and the adjustment function on gastrointestinal hormone of serum of patients caused by the warming and nourish effect with moxibustion.Methods Eighty-four superficial gastritis Patients due to the spleen and stomach weakness were divided into group 1(treated by warming moxibustion for twenty minutes)(n=28),group 2(treated by warming moxibustion for forty minutes)(n=28),and drug(n=28)groups.The changes of the content of the Prostaglandin E2(PGE2)、Somatostatin(SS)and Epidermal growth factor(EGF)were observed before and after treatment between 3 groups and the clinical effect in different time.Results ①All 3 groups were compared after treatment,their clinical effect had no significant difference(P＞0.05):②Compared with pre-treatment,the superficial gastritis symptom score had a very significant difference after the treatment(3.07±1.54)、(3.11±1.40)、(3.79±2.25)and during the 1 month follow-up(2.25±1.32)、(2.57±1.10)、(4.11±2.48),(P＜0.01);③After treatment,the content of the PGE2 of the serum was increased obviously,compared with pre-treatment.There was a significant difference in each group(33.751±1.267)pg/ml、(33.774±8.583)pg/ml、(32.583±8.259)pg/ml,(P＜0.05);After warming moxibustion for forty minutes,the content of the EGF of the serum was increased obviously,compared with pre-treatment,showing a significant difference(1.331±0.823)pg/ml,(P＜0.05).Conclusion ①All of the three treatment methods had significant curative effect,and the curative effect had no significant difference among these 3 groups.But the moxibustion groups were markedly higher than the drug group in long-term result;②The moxibustion had established adjustment function on gastrointestinal hormone of the superficial gastritis patients due to the spleen and stomach weakness,which suggested that the gastrointestinal hormone may participate in its onset and the process of pathology and physiology.

Objective To construct a luciferase reporter gene vector of perforin promoter and methylate it in vitro. Methods The promoter of the human peffofin was amplified by PCR, cloned into pMD18-T vector and subcloned into pGL3-Basie vector, and then con-finned by restriction mapping and DNA sequencing. The regions of interest were excised with the appropriate restriction endonucleases, then it were methylated with methylase Sss I(M. SssI)and S-adenosymethioine(SAM), and methylation was confirmed by digestion with appropri-ate methylation sensitive enzyme AciI and agrose gel electrophoresis, and then the fragment was relegated back into the promoter-reporter constructor pGL3-Basic. Results The result of DNA sequencing showed that the sequence of cloned promoter was right. The result of diges-tion methylation with appropriate methylation sensitive enzyme showed that perforin promoter was completely methylated. Conclusion The promoter of perforin was successfully cloned and completely methylated in vitro, which provided an important basis for the study of transfec-tion.

Objective To determine the relationship between serum soluble Klotho (sKL) level and adverse outcome in maintenance hemodialysis (MHD) patients.Methods One hundred and twenty nine cases of MHD patients were collected prospectively.Serum sKL was detected by ELISA.Abdomen lateral plain was used as a criterion to determine the abdominal aortic calcification.The abdominal aortic calcification score (AAC) was calculated.Cox regression analysis was used to determine the risk factor of cardiovascular death (CVD) in MHD patients.Kaplan-Meier showed the relationship between sKL and CVD in MHD patients.Results There were 27 cases (20.9％) of allcause death and 19 cases (14.7％) of cardiovascular death.The median sKL was 612.6(379.2-816.6) nig/L,and log[iPTH] was an independent factor of sKL concentration.Low sKL had high AAC and CVD death rate.Kaplan-Meier method showed that the all-cause death rate was similar between two groups,and CVD death rate increased significantly in low sKL patients (P=0.036).Cox regression indicated that lower sKL level was associated with high CVD death rate [OR=0.352,95％CI(0.127-0.977),P=0.045].After adjustment for the general condition,biochemical indicators,the relationship still existed [OR=0.331,95％ CI (0.117-0.933),P=0.037].In no or mild vascular calcification patients (AAC ≤4),compared with high sKL patients,low sKL patients had no significant difference rate in all-cause mortality.The CVD mortality was significantly higher in high sKL (P=0.035) compared with low sKL.In severe calcification group (AAC ＞ 4),all-cause death and CVD death rates were similar between different sKL groups (P=0.991 and 0.522,respectively).Conclusions Lower sKL has the high CVD death rate and sKL level decreasing is an independent risk factor for CVD death in MHD patients.The lower sKL concentration in MHD patients with no or mild calcification may predict CVD mortality.This study suggests that sKL levels may be helpful in predicting the outcome of patients with MHD.

Objective To analyze the relevant factors of cerebral stroke recurrence in order to provide reference for clinical prevention. Methods A total of 300 patients with cerebral stroke treated in our hospital from April 2012 to April 2015 were selected and divided into the primary onset group (206 cases) and the recurrence group (94 cases). The age, blood pressure, blood sugar, blood lipids, smoking, drinking, carotid atherosclerosis, type of stroke, family history of stroke and emotions of the two groups were compared. Univariate and multivariate analysis was conducted. Results The differences of patients' age, blood pressure, blood sugar, blood lipids, smoking, carotid atherosclerosis, family history of stroke, the respect such as emotional between two groups were statistically significant (P<0.05), the differences of drinking and stroke type had no statistical significance (P>0.05), and old age, hypertension, hyperglycemi a, hyperlipi-demia, smoking, carotid atherosclerosis, family history of stroke, emotional behavior disorder were independent risk fac-tors for recurrence of stroke(P<0.05). Conclusion For the patients with primary onset cerebral stroke and potential risk of cerebral stroke, their medical history and family history should be learned in detail, monitoring of their blood pres-sure, blood glucose and blood lipids should be enhanced, and meanwhile good life habits should be developed under guidance and positive and optimistic mentality should be cultured.

Human cytomegalovirus glycoprotein complex Ⅱ (gC Ⅱ ) consists of two glycoproteins, gM and gN. Although gC Ⅱ specific IgG purified from HCMV positive patient sera can neutralize HCMV, there has been no report on the generation of virus-neutralizing antibodies by immunizing with one epitope of gM. The epitope, termed MAD, was screened from random phage peptide library by subtractive strategy. The peptide sequence of MAD was highly homologous with 32~38 amino acids of HCMV gM. Mice immunized with MAD coupled with keyhole limpet hemocyanin (KLH) could produce specific antibodies against MAD, and the antibodies obtained could bind not only native HCMV particles, but also the recombinant gM30～78 peptide. ELISA analysis results showed that MAD could specifically bind HCMV-positive human serum samples. Virus-neutralizing assay results demonstrated that the antibodies against MAD could inhibit HCMV strain AD169 entering the human embryonic lung cells. The results suggested that MAD could be used as a new potential protective antigen in the development of HCMV vaccine.

Objective To explore the association of fibroblast growth factor-23 (FGF23) with abdominal aortic calcification(AAC) and adverse outcomes in maintenance hemodialysis patients.Methods One hundred and fourteen cases of MHD patients were collected prospectively.Serum intact FGF23 was detected by ELISA.Abdomen lateral plain was used as a criteria to determine the abdominal aortic calcification and the abdominal aortic calcification score was counted.Logistic regression analysis was used to determine the risk factors of AAC.Kaplan-Meier analysis was applied to compare the survival rate among different groups and COX regression analysis was used to determine the association of FGF23 and mortality in MHD patients.Results Seventy-six patients present abdominal aortic calcification.The median of AACS was 4.0(0.0,11.0).The median level of FGF23 was 7277.4(2535.0,9990.8) pg/ml.The median follow-up duration was 72.0(67.8,72.8) months.During the follow-up,22 patients (19.3％) died of all-cause death and 17 cases (14.9％) died of cardiovascular diseases.Serum FGF23 level was positively correlated with AAC (r=0.285,P=0.002).Logistic regression analysis showed that longer age (OR=1.059,95％CI:1.020-1.100,P=0.003) and dialysis vintage (OR=I.009,95％CI 1.000-1.017,P=0.039),smoking history (OR=3.010,95％CI 1.177-7.696,P=0.021) and higher FGF23 level(OR=2.831,95％CI 1.010-7.937,P=0.048) were independent risk factors of moderate to severe AAC in MHD patients.Kaplan-Meier survival curves showed that the patients with AACS≥ 5 had significantly higher all-cause mortality(P=0.028) and CVD mortality (P=0.035) than those with AACS ＜ 5.However,the Kaplan-Meier analysis showed no significant difference regarding the level of serum FGF23 with the all-cause and CVD mortality.Cox regression demonstrated that FGF23 was not associated with increased mortality risk,neither in crude nor in multivariate adjusted models.Conclusions Abdominal aortic calcification had a high prevalence in MHD patients.The all-cause and CVD mortality was higher in patients with moderate to severe AAC.FGF23 was an independent risk factor of moderate to severe AAC,but it can't yet be a predictor for the allcause and CVD mortality of MHD patients.
