Objective To systematically analyze therapeutic effects of extracorporeal photopheresis (ECP) on refractory steroid-resistant,-dependent or-intolerant graft-versus-host disease (GVHD),to compare remission rates of skin GVHD in detail.Methods Databases were searched for studies concerning remission rates of GVHD after the treatment with ECP,and relevant data were extracted and pooled by using meta-analysis with STATA 12.0 software.Results A total of 22 literatures were reviewed,including 787 patients with refractory GVHD.Meta-analysis showed that the pooled complete remission (CR) rate and overall remission (OR) rate were 57％ (95％ CI:47％-66％) and 79％ (71％-86％) respectively in patients with acute GVHD,27％ (21％-33％) and 63％ (58％-69％) respectively in patients with chronic GVHD,77％ (71％-82％) and 87％ (82％-91％) in patients with acute skin GVHD,as well as 39％ (30％-48％) and 70％ (63％-77％) in patients with chronic skin GVHD.Conclusion ECP is an effective therapy for refractory GVHD,especially for skin GVHD.

Objective To evaluate the prognostic value of combing pre-procedural red cell distribution width(RDW)with serum uric acid(SUA)levels in patients with acute coronary syndrome(ACS)undergoing percutaneous coronary intervention(PCI).Meth-ods A total of 1 52 consecutive patients with ACS who underwent successful PCI within 12 hours after onset of symptom were en-rolled.RDW and SUA were determined within 12 hours before PCI.The patients were divided into 3 groups according to the cut-off values showed by receiver operating characteristic(ROC)curve:73 cases in group I,RDW<14.5% and SUA<402 μmol/L;50 cases in group Ⅱ,RDW< 14.5% and SUA≥ 402 μmol/L,RDW≥ 14.5% and SUA< 402 μmol/L;29 patients in group Ⅲ,RDW>14.5% and SUA>402 μmol/L.The pre-procedural RDW and SUA status associated with 30 days any cause mortality and major adverse combined cardiac events including revascularization,non-fatal recurrent myocardial infarction,secondary heart failure,rehos-pitalization and death were analyzed.Results Pre-procedural RDW and SUA level predicted 30 days cardiac mortality,RDW and SUA level correlated linearly(r=0.336,P =0.001).30 days major adverse combined cardiac events and any cause mortality were significantly different among the three groups(P =0.031,P =0.012).Conclusion Pre-procedural RDW≥ 14.5% and SUA≥402μmol/L indicates poor prognosis in ACS patients underwent successful PCI.Therefore the combination of RDW and SUA measure-ment should be taken into consideration for risk stratification to decide about the management strategies in ACS patients.

Objective To evaluate the incidence of nasopharyngeal hemorrhage after radiotherapy of nasopharyngeal carcinoma (NPC) in order to adjust adequately the dose of fractionated stereotactic radiosurgery (FSRS). Methods Eighteen NPC patients were treated by FSRS following conventional radiotherapy of D T65～74?Gy. Of them, 5 patients (T 4) with uncontrolled lesions received a boost dose of 24～40?Gy/6～8 f and 13 patients (T 2～3 ) with local recurrence received their second course of treatment with different regimens. Group A: 8 patients received routine radiotherapy 30～40?Gy followed by FSRS 24～30?Gy/6～9 f; Group B: 5 patients received FSRS 40～42?Gy/6～8 f alone. Results The frequency of nasopharyngeal hemorrhage was 3/5 for skull base invasion (T 4 ) lesions. The incidence of morbidity for re radiation after local recurrence of T 2～3 tumor was 1/8 in Group A and 1/5 in Group B.Conclusions The frequency of nasopharyngeal hemorrhage is high in skull base invasion by NPC (T 4).Therefore the dose of FSRS combined with conventional radiotherapy should be limited when re treating local recurrence of NPC.

Objective: To investigate the characteristics of Behavior Styles personality dimension among subjects of dif- ferent age, genders, marriage status, and occupations. Methods: After subjects fulfilled Chinese Personality Scale (QZPS), score differences of Behavior Styles and its sub- factors were compared among age, genders, marriage status, and occupa- tions. Results: Significant differences were detected among different age, genders, and occupations. Males have lower scores than females; the elder the subjects, the higher the scores; executives and technicians have the same scores, and both have higher scores than workers and peasants. Some interactions were also significant. Conclusion: There were sig- nificant differences among subjects of different gender, age, and occupation.

Objective To establish a nested-real-time-PCR for the detection of IL-21R mRNA in peripheral blood mononuclear cells(PBMC)of patients with rheumatoid arthritis,and explore its clinical significance.Methods The outer primers of span intron and inner primers were designed for nested-real-time-PCR.To increase specific template,the concentration of primers and enzyme,cycle times were decreased in the first amplification,and the real-time fluorescent quantity assay was performed in the second amplification.The ?-actin gene was used as internal reference,and the results were presented as the ratios of IL-21R mRNA to ?-actin mRNA.Results IL-21R mRNA was detected in 60 patients with RA and 30 healthy controls.The expression of IL-21R mRNA gene in the patients with RA was increased,and the statistical analysis has significant differences(P0.05),but a significant difference was found in the patients of grade III compared with those of grade I and II(P

Continuous renal replacement therapy( CRRT) employs convection and adsorption to re-move pro-and anti-inflammatory mediators from plasma, helping to restore the immunologic homeostasis. CRRT also provide uninterrupted clearance of retained endogenous and exogenous toxins, along with acid-base,electrolyte,hemodynamics and volume homeostasis.CRRT may improve outcomes in critically ill pa-tients with sepsis-induced acute kidney injury,septic shock and multiple organ dysfunction syndrome.Region-al citrate anticoagulation, as compared to unfractionated heparin, report better filter survival times and less bleeding.Antibiotic dosing decisions should be individualized to take into account patient-related,CRRT-relat-ed,and drug-related factors.

Primary aldosteronism (PA) is a common form of secondary endocrine hypertension,which is characterized by hypertension,hypokelamia,myathenia,elevated serum aldosterone concentration and suppressed plasma renin activity.Besides,accumulating research evidences showed that parathyroid hormone (PTH) level was elevated in patients with primary aldosteronism,accompanied by secondary hyperparathyroidism.This review systemically introduces the interaction between aldosterone and PTH in PA patients.

Objective To observe the effect of bone marrow mononuclear cells (BMMNCs) transplantation on high mobility group box1 (HMGB1) migration in stroke mouse. Methods BMMNCs were harvest and injected intravenously into stroke mouse model; modified neurological severity scores(mNSS) were tested; brain infarct vol-ume and related protein expression levels were measured, then HMGB1 migration were observed. Results mNSS score and brain infarct volume in transplantation group weresignificantly lower than vehicle group , while HMGB1 expression were significantly higher than vehicle group. The expression levels of RAGE and TNF-α in transplanta-tion group were significantly lower than vehicle group. Immunofluorescence assay showed that the release of HMGB1 in brain penumbra area of transplanted mouse was significantly less than vehicle groups. Conclusions BMMNCs transplantation could inhibit the release of HMGB1 in mouse brain.

The key reason for reparative process interruption of femoral head necrosis is the formation of hardening layer, which make it hard for medicine to act on the necrosis center. The research on formation mechanism of hardening layer is limited and the reason for reparative process interruption is unknown. Based on lots of pathological section and literature data, four hypotheses about the reason for reparative process interruption are proposed, including resource competition, damage of stress, disturbance of nerves and stasis of blood vessel. The internal mechanism of incomplete reparation and chronicity of hardening layer was analyze from different aspects. The four hypotheses provides a new thinking for study the reason for reparative process interruption.
