Objective To investigate the efficacy and safety of polyethersulfone highlux dialyzer for maintenance hemodialysis patients. Methods Thirty-six maintenance hemodialysis patients were randomizedresigned into two groups,polyethersulfone 14HF(PES-14HF)group and polyethersulfone 150DS(PES-150DS)group,based on a random number table. The patients from two groups received different dialyzer hemodialysis for over 3.5 hours/each time respectively. Changes of serum creatinine,urea,β2-microglobulin,hemoglobin and albumin levels were measured for determination of the efficacy and safety evaluation. Results In the comparison between before or after hemodialysis,the level of serum creatinine,urea,β2-microglobulin levels decreased significantly to(333.8 ± 89. 5)μmol/L,(7. 0 ± 1.9)mmol/L,(22. 9 ± 1.7)mmol/L from(990. 2 ± 191.2)μmol/L,(24. 7 ± 4. 1)mmol/L,(13.6 ± 3.3)mmol/L respectively in the PES1 4 HF group(P ＜ 0.01);the level of serum creatinine,urea,β2-microglobulin levels decreased significantly to(395.5 ± 86.1)μmol/L,(8. 1± 2. 8)mnol/L,(18.0 ± 3.0)mmol/L from(1059. 5 ± 179. 4)μmol/L,(25.3 ± 4. 8)mmol/L,(22. 3 ± 2. 9)mmol/L respectively in the PES-150DS group(P ＜ 0. 01). We found no significant differences in each measured index between two types of hemodialysis(P ＞ 0. 05 respectively),while the level of β2 -microglobulin levels decreased more significantly in the PES14HF group(42. 81 ± 12. 48)mg/L than PES-150DS group(24. 21 ± 13. 24)mg/L(P =0. 017). Conclusions The efficacy and safety of the PES-14HF hollow fiber membrane hemodialyzer is equivalent to that of the PES-150DS hemodialyzer in hemodialysis for uremic patients.

Objective: To evaluate the effects of dietary behaviors on the risk of hypertension, diabetes and cardiovascular diseases. Methods: A total of 12 208 subjects aged 18-60 years old were investigated by questionnaires to collect demographic data, dietary behaviors and lifestyle information, when they did health examination in a tertiary hospital in Beijing from 2014 to 2019. During the observation period of five year, the incidence of hypertension, diabetes and cardiovascular diseases were collected through health examination files every year. The multivariate logistic regression model was employed to analyze the associations of dietary behaviors with hypertension, diabetes and cardiovascular diseases. Results: The study included 6 218 ( 50.93% ) males and 5 990 ( 49.07% ) females. The cumulative incidence rates of hypertension, diabetes and cardiovascular diseases were 7.75%, 2.72% and 3.49%, respectively. The multivariate logistic regression analysis indicated that the high-sodium diet ( OR=1.422, 95%CI: 1.191-1.697 ) , eating fast ( OR=1.457, 95%CI: 1.102-1.974 ), eating more refined grain ( OR=1.251, 95%CI: 1.050-1.490 ) and drinking milk less than once a week ( OR=1.316, 95%CI: 1.022-1.697 ) were risk factors for hypertension. The high-sodium diet ( OR=1.344, 95%CI: 1.048-1.725 ), eating fast ( OR=1.733, 95%CI: 1.046-2.871 ), eating more meat ( OR=1.651,95%CI: 1.263-2.158 ) were risk factors for diabetes. High-sodium diet ( OR=1.501, 95%CI: 1.192-1.889 ) was risk factors for cardiovascular disease. Conclusion The diet with high sodium, more meat and refined grain as well as eating fast can increase the risk of hypertension, diabetes and cardiovascular diseases.

To investigate the therapeutic effects and associated complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT). 40 patients with various malignant hematopoietic diseases received allo-PBSCT. The preparative regimens were based on BUCY2 or modified BUCY2. The acute graft-versus host disease (aGVHD) was prevented by cyclosporin A and short-term MTX regimen in all patients. Two patients from donors with one fully mismatched HLA on DRB1 locus and 4 from unrelated donor also administered Zenapox (CD25 MAb) at dosage of 1 mg/kg every day on the day before transplantation and day 4 after transplantation. These 6 patients were also treated with mycophenolate mofetil (MMF). Transfusion of the donor cells: The median of the transfused nucleated cells was 5.38 x 10(8)/kg and that of the CD34+ cells was 7.8 x 10(6)/kg respectively. All the patients gained hematopoietic reconstruction except one who died of infection before engraftment. Seven patients got II degrees-IV degrees aGVHI) and the incidence was 17.5%. Fourteen patients got cGVHD and the incidence was 53.8% in the patients who survived over 6 months. Twenty-eight patients had fever or other characteristics of infection. The median follow-up time was 13.8 months. The incidence of transplantation related mortality (TRM) was 17.5% and 2 patients relapsed (5.0%). It was concluded that allo-PBSCT can reconstruct hematopoiesis quickly and is a favorable therapeutic method for leukemia.

Objective To investigate whether homocysteine(Hcy) induces apoptosis of endothelial cells via a pathway involving caspases3 and whether simvastatin antagonizes the proapoptotic effects of Hcy by regulating c-IAP. Methods Human umbilical vein endothelial cells(HUVEC) were treated with Hcy,with or without simvastatin,for 24 h.Cell apoptosis was evaluated by Annexin V staining and flow cytometery,as well as TUNEL.The mRNA and protein levels of caspase3,c-IAP-1 and c-IAP-2 were analyzed by RT-PCR and Western blot,respectively. Results Treatment with both low(0.5 mmol/L) and high(3.0 mmol/L) concentrations of Hcy-induced HUVEC apoptosis was accompanied by an increased level of caspase3 expression and activation,together with decreased c-IAP-1 and c-IAP-2 level.Simvastatin upregulated c-IAP-1 and c-IAP-2 expression while attenuated Hcy-induced apoptosis and caspase3 activation. Conclusion Hcy may induce HUVEC apoptosis via a pathway involving caspase3,which can be partially antagonized by simvastatin,possibly through upregulated c-IAP-1 and c-IAP-2 expression.

Objective To study the relationship of clinical manifestation and pathological changes and prognosis in Henoch-Schonlein purpura nephritis(HSPN)in children.Methods Clinical and pathological characteristics of 42 children with HSPN were analysed.Among them,40 children were detected of angiotensin-convertion enzyme(ACE)gene and had been followed up.Results Among them,there were 9 cases of level Ⅰof pathological types,21 cases of level Ⅱ,12 cases of level Ⅲ,but no cases of level Ⅳ.Ⅰand Ⅱ level were found in those cases of clinical manifestation with solitary hematuria and albuminuria.Pathological grades were Ⅰ,Ⅱ and Ⅲ levels in the cases of hematuria and albuminuria.Pathological types of nephrotic syndrome(NS)were Ⅱ and Ⅲ level,which were of more gross hematuria than those of other grades.ACE gene DD had serious pathological damnification.Conclusions Change of pathology cannot only be anticipated by clinical manifestation of HSPN.But if pathological damnification gets more serious,the albuminuria gets more serious.Gross hematuria and albuminuria can serve as indicators of biopsy.NS of ACE DD type have serious pathological damnification.Children with HSPN has favourable prognosis in the future.

OBJECTIVESTo unravel the molecular mechanism of proliferation inhibition induced by transfection of pemt2-cDNA into rat CBRH-7919 hepatoma cells.

METHODSWe started with the highly expressed PEMT2 clone. Cell culture and Western blotting techniques were used to examine the expression of cyclinD1/CDK4, cyclinE/CDK2, phospho-Rb, caspase-3, c-jun and caveolins.

RESULTSOur results showed that CDK4, CDK2, phospho-Rb and c-jun were down regulated in the pemt2 highly expressed cell clone. The high expression clone of pemt2-transfected cells also showed over expression of caspase-3.

CONCLUSIONThe reductions of proliferation and apoptosis of pemt2 transfected cells could be related to the G1 phase arrest induced by down-regulation of the cell cycle-associated proteins.

The cupping spot is considered as one kind of skin change due to cupping treatment. With literature regarding cupping spot, the influencing factors and value of cupping spot in clinical diagnosis and treatment were analyzed, which could make a further exploration on the action mechanism of cupping treatment. The literature showed that the formation of cupping spot was related with cupping temperature, pressure, cup-retaining time, cupping area, individual difference and health condition, etc; cupping spot had the ability to assist diagnosis, prevent disease, cure disease and evaluate clinical efficacy. Previous studies on cupping spot have already made some progress, and played a positive significance on finding cupping rule and studying its mechanism. However, the research for this area is still in the primary stage, which needed deeper study to reveal scientific connotations of cupping spot.

OBJECTIVETo determine the prevalence of depression among cancer patients and its influencing factors.

METHODSWe investigated 7967 cancer patients who lived in communities with cluster sampling based on 'Shanghai Cancer Patient Database'. They were investigated through questionnaires and completed the Zung Self-rating Scale. 6694 questionnaires were identified as 'qualified'. We calculated the prevalence of depression and determined the factors with logistic regression model.

RESULTSThe prevalence rate of depression among cancer patients in communities was 24.74% (95% CI: 23.71% - 25.79%). Results from multi-factor analysis showed that duration since diagnosis, stages at diagnosis, metastasis, therapeutics, KPS scores, and pain VAS scores were the important factors.

CONCLUSIONEarly detection, improving the curative effect and providing community health services could reduce the prevalence of depression.

OBJECTIVETo analyze and evaluate the acceptability of mifepristone compatible with misoprostone versus conventional surgical abortion among women under unwanted early pregnancy, so as to help the unexpected pregnant women to choose the satisfactory abortion, and to provide the evidence for clinicians to make a proper clinical decision.

METHODSSix medical databases were searched, including MEDLINE, EMBASE, Cochrane library, CBMdisc, CNKI and VIP, together with twelve journals hand-searched, and references of included studies additionally searched. Two qualified reviewers reviewed the original articles, evaluating qualities of articles, and extracting data independently. After heterogeneity test, the data was pooled using Revman software if capable, or descriptive analysis was applied.

RESULTSIn total, nine original clinical controlled trials were included, containing 3565 cases. Before abortion, more unwanted pregnant women chose the medical abortion because they believed medical abortion was less painful than surgical abortion (OR = 466.51, 95% CI: 91.37 - 2381.88), but medical abortion was less time-consuming than surgical abortion (OR = 0.02, 95% CI: 0.01 - 0.06). After abortion, satisfaction with medical abortion was similar to that with surgical abortion, with insignificant difference (P = 0.89). However, second choice and recommendation rates of medical abortion were much higher than those of surgical abortion with OR and 95% CI as 2.72, 2.13 - 3.47 and 4.19, 2.16 - 11.16, respectively.

CONCLUSIONSMedical abortion was less painful than surgical abortion and the rate of second choice and recommendation to others were all also higher than those of surgical abortion. However, the process of medical abortion was not as quick as surgical abortion but the satifacation of both methods seemed similar. Therefore, the two artificial abortion methods were not recommended to replace each other at the present time.
