BACKGROUND:To evaluate the psychological characteristics of the patients waiting for renal transplantation in order to analyze coping style, thus perform the corresponding personalized clinical psychological intervention which is conductive for patients to face reality and disease. OBJECTIVE:To investigate the psychological characteristics of the patients waiting for renal transplantation and to analyze the effect of different social factors on the coping style of patients and to explore the corresponding clinical mental intervention method METHODS:Fifty-eight patients waiting for renal transplantation and 60 patients without renal transplantation were randomly selected from Second Department of Urology, Organ transplantation Center, the 309th Hospital of PLA between February 2009 and August 2010, the patients were required to fil in a psychological questionnaire form using the currently general used medical response. The effect of social factors on the coping style and psychological stress status was analyzed with multi-factor Logistic regression analysis. RESULTS AND CONCLUSION:From the questionnaire survey, the evasive and yielding value scores of the patients waiting for renal transplantation were significantly higher than those of the patients without renal transplantation (P<0.05), but there was no significant difference of confrontation score between the patients (P>0.05). It indicated that the psychological pressure of the patients waiting for renal transplantation was bigger that of the patients with out renal transplantation, which may related with course of the disease, cost and the rejection after transplantation for the patients has to endured. Multi-factor Logistic regression analysis showed that sex, education, income, payment methods and age of the patients were al related with the confrontation, evasive and yielding scores, as those with technical secondary school education or better got the best confrontation score while those with annual income less than 60 000 yuan got the highest score in evasive and yielding styles. The results show that income and education level of patients are the main factors that affect the coping style and psychological stress status of the patients waiting for renal transplantation, treating the patients with reasonable renal clinical care interventions can help the patients face to the disease positively and can reduce the damage of transplantation to the psychology of the patients.

Based on a review of currently published 40 papers ( 20 published in recent 5 years, 20 published in recent 10 years) on gold nanoparticles for cancer radiotherapy, the general characteristics, theoretical studies, in vitro experiment, in vivo experiment,and the clinical prospects of targeted radiotherapy with gold nanoparticles were reviewed. Three key aspects guarantee further investigation for the full understanding of the radiosensitization effect of gold nanoparticles:the cellular localization and tissue distribution of nanoparticles and influential factors;the micro dose enhancement effect of gold nanoparticles, and the molecular biological mechanism. More cross disciplinary collaboration, research, development and translation are needed before gold nanoparticles are put into clinical trials.

OBJECTIVETo compare the difference in clinical efficacy on bronchial asthma at chronic persistent stage between acupuncture for warming yang and benefiting qi and seretide.

METHODSOne hundred and eighty patients of bronchial asthma at chronic persistent stage were randomized into an acupuncture group and a western medication group, 90 cases in each one. In the acupuncture group, acupuncture for warming yang and benefiting qi was applied at Dazhui (GV 14), Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1), Jianshi (PC 5), Zhigou (TE 6), Taixi (KI 3) and Zusanli (ST 36), once every two days. In the western medication group, inhalation therapy with seretide was applied, 1 to 2 inhalations each time, twice a day. The treatment for 20 days was as one session in the two groups, at the intervals of 2 days after each session. Four sessions of treatment were required. The immune function indices were observed before and after treatment in the patients of two groups, named immunoglobulin IgG, IgM and IgE; peripheral T lymphocytes (CD3+), helper T lymphocytes (CD4+), inhibitory T lymphocytes (CD8+) and the ratio of CD4+ and CD8+; as well as the pulmonary ventilation function indices, named maximum pulmonary expiratory flow (PEF), forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). The clinical efficacy was compared between the two groups.

RESULTSThe total effective rate was 93.3% (84/90) in the acupuncture group, better than 88.9% (80/90) in the western medication group (P < 0.05). After treatment, the immune function indices and pulmonary ventilation function indices were apparently improved as compared with those before treatment in the two groups (all P < 0.05). The improvements in the acupuncture group were much more significant (all P < 0.05).

CONCLUSIONAcupuncture for warming yang and benefiting qi effectively controls the symptoms of bronchial asthma at chronic persistent stage and improves immune and pulmonary functions. The efficacy is better than that of seretide.

Objective To test the accuracy and reliability of Axesse accelerator for volumetric modulated arc therapy (VMAT).Methods The accuracy and reliability of Axesse accelerator for VMAT were tested in a stepwise manner, from the simple to the complex and from the part to the whole.For the parts of the system, the stability of dosimetric output and the position accuracy of multi-leaf collimator (MLC) were tested.For the process of the system, the variable VMAT dose rates and gantry speed modulation, the MLC speed and dose rate modulation, and dosimetric verification in patients were tested.Results Compared with fixed gantry irradiation, the variation in dosimetric output was below 1.0% for rotary irradiation including the slide rotary irradiation of the dynamic MLC.The MLC position error of 0.5 mm was visible using the electronic portal imaging system of Axesse, iViewGT 3.40.The MLC position accuracy was within 1 mm for fixed gantry irradiation and rotary irradiation.In the range of the dose rate applied in clinical practice, the testing results of variable VMAT dose rates and gantry speeds as well as variable dose rates and MLC speeds showed that the variation between different strip-field beam intensities was below 2.0%.Using a gamma criterion of 3 mm/3%, the pass rates in dosimetric verification of patients with cervical cancer, prostate cancer, and breast cancer were 96.52%, 95.72%, and 98.83%, respectively.Conclusions The Axesse system can precisely control MLC motion, variable dose rates, and gantry speeds in VMAT.The Axesse system is accurate and reliable for VMAT.

Objective To study the influence of hydrogen sulfide (H2 S)on the mitochondrial function of pulmonary artery smooth muscle cells of the rats with high pulmonary blood flow pulmonary hypertension, and to clarify the function and its mechanism in the occurrence of high pulmonary blood flow pulmonary hypertension.Methods A total of 27 rats were randomly divided sham operation group,operation group,and operation+sodium hydrosulfide (NaHS)group (n=9).The pulmonary hypertension rat model was built by left lung resection.After fed for 35 d, the mean pulmonary artery pressure (mPAP),ratio of right ventricle/body weight (RV/BW),and ratio of right ventricle/(left ventricle+septum)[RV/(LV + S)]of the rats in three groups were measured.The plasma H2 S levels and the CSE activities in pulmonary artery tissue of the rats were detected;the activities of total mitochondrial ATP enzyme,superoxide dismutase (SOD),glutathione peroxidase (GSH-Px)and malondialdehyde (MDA)levels were determined;the ultrastructure of pulmonary artery smooth muscle mitochondria was observed through transmission electron microscope.Results Compared with sham operation group,the plasma H2 S level and the CSE activity in pulmonary artery tissue of the rats in operation group were decreased(P<0.01);the mitochondrial membrane of pulmonary tissue was swelling, and the mitochondrial activity was decreased (P<0.01);the mitochondrial ATP enzyme,SOD and GSH-Px activities were significantly decreased,and the MDA level was significantly increased (P<0.01).Compared with operation group,the H2S level in plasma and the activity of CSE in pulmonary tissue of the rats in operation + NaHS group were increased (P<0.01 );the mitochondrial membrane swelling was reduced, and the vitality was restored;the ATP enzyme, GSH-Px, and SOD level in pulmonary tissue were significantly increased (P<0.01),and the MDA level was significantly reduced (P<0.01).Conclusion H2 S can enhance the activities of mitochondrial ATP enzyme,GSH-Px,and SOD,and decrease the mitochondrial lipid peroxidation level,thus it plays a protective effect on rat pulmonary artery smooth muscle.

[Abstract ] Objective The mechanism of psychological stressi-nduced damage to vascular endothelial cells (VEC) is not yet clear.This study was to investigate the impact of psychological stress on the NO level and NO-related regulatory protein expression in the plasma of rat models of psychological stress-induced VEC injury. Methods Twenty male SD rats were equally randomized into a con-trol group and a model group, the former raised together, with water regularly fed at 9:00 and 21:00 hours for 10 minutes a day, while the latter raised alone, with water regularly fed at the same hours for 10 minutes a day for the first 7 days and then with water or an empty bottle at the same hours for 10 minutes a day according to the random table.Ninety days later,all the rats were intraperitoneally injected with normal saline at 0.2 ml per 100 g body weight twice a day.Then the behaviors of the animals were observed by open field tests, the contents of cortisol (COR),adrenaline (Adr), and endothelin-1 (ET-1) in the plasma measured by ELISA, the NO level detected by the nitrate reductase method, and the expression of NO-related regulatory proteins in VECs determined by LC-ESI-MS. Results Com-pared with the control group, the model rats showed significant increases in the vertical score (7.00 ±0.70 vs 11.28 ±1.79), horizontal score (37.60 ±4.500 vs 56.25 ±1.71), and total score (44.50 ±5.50 vs 67.25 ±2.98) (P<0.01) as well as in the levels of COR ([65.28 ±2.21] vs [83.85 ±1.95] ng/mL ) and Adr ([3.85 ±0.35] vs [15.14 ±3.97] pg/mL) (P<0.01), but a remarkable de-with vacuoles in the VECs in the model group and structural integrity, ridge clarity, and tight pack in the VEC mitochondria in the con-trol. Conclusion Psychological stress induced by empty bottle stimulation can reduce the NO level and the expression of NO-related regulatory proteins in the plasma, which may cause both functional and structural damages to VECs.

Objective To compare the applied value of BK virus DNA load detection in urine and plasma for diagnosis BK virus nephropathy (BKVN) in renal transplantation recipients.Method In 88 renal transplantation recipients receiving renal allograft from February 2011 to January 2012 in our institute,BK virus DNA load in urine and plasma was detected by using real-time PCR,and renal biopsy was performed on the recipients with gradual deterioration of the graft function or the loads of BKV replication being very high.The diagnosis of BKVN was confirmed by using immunohistochemistry.Results Of 88 recipients,there were 35 cases (39.8％) of viruria,18 cases (20.5％) of viremia and 5 cases (5.7％) of BKVN.The median BKV DNA load in both urine and plasma in BKVN recipients was significantly higher than in non-BKVN recipients (P＜0.05).The viruria sensitivity and specificity for BKVN were 100％ and 57.3％ (P =0.03),and the viremia sensitivity and specificity for BKVN was 100％ and 82.9％ (P =0.0002),respectively.We regraded viral load ≧ 105 copies/mL in plasma or ≥107 copies/mL in urine as the best discriminant cut-off value to predict the disease and to identify patients at risk of developing BKVAN.The positive cut-off value of urine's positive predictive value (PPV+) was 26.3％ and negative predictive vaule (PPV-) was 95.7％,and the positive cut-off value of plasma's positive predictive value (PPV +) was 83.3％ and negative predictive vaule (PPV-) was 98.8％.Conclusion The viral load ≥105 copies/mL in plasma can be used as the best discriminant cut-off value to predict the disease and to identify patients at risk of developing BKVAN,but the cut-off value of urine should be only used for screening BKV infection.

Objective To investigate the epidemiological characteristics of polyomavirus type BK infection in renal transplant recipients.Method We systematically screened for active BKV infection preoperation and at 0.5,1,3,6,9,12 and 15 months after transplantation in 116 renal transplant recipients.The screening tests included urine cytology (by the Papanicolaou method) and BKV DNA PCR (the kit for testing the BK virus) assay of both urine and plasma,and the results were recorded.Renal biopsy was performed if the graft function was deteriorated gradually or the loads of BKV replication were very high.Routine histopathological examination and immunohistochemistry were performed on renal tissues from partial patients who received the tests of renal biopsy.Result Throughout the follow-up of 15 months,urinary decoy cells (median 8/10 HPF,[1～ 48/10 HPF]),BKV viruria (median 2.63 × 105 copies/mL,[1.78 × 103 ～ 8.54 × 109 copies/mL]),BKV viremia (median 2.70 × 104 copies/mL,[1.95 × 103 ～6.31 × 106 copies/mL]),and BKVAN (4 patients) occurred in 53.46％,24.17％,20.72％ and 3.45％ of renal-transplant recipients,respectively.The positive rate of the decoy cell and BKV DNA in urine reached the peak at the third month to the ninth month after transplantation,and the peak time of the BK viremia was the fifth month post-transplantation throughout the follow-up period.The change in BKV DNA level remained constant in blood and urine throughout the follow-up period.Conclusion The peak time of BKV infection was apparently three to nine months after transplantation,suggesting the importance of monitoring urine cytology and BKV DNA loads in post-transplantation patients closely during this period in order to reduce BKVAN after transplantation.

Objective To investigate the influence of BK virus (BKV) activation in renal transplant recipients on the renal allograft function.Method Recipients receiving renal transplantation during 2010.3-2011.4 were sdected as objectives,the urine and peripheral blood samples of them were taken and real-time PCR assays were performed to detect BKV DNA at 0.5,1,3,6,9,and 12 months post-transplantation.Results Among 88 recipients,BKV viruria occurred in 27 (30.68％) patients,and sustained viruria occurred in 17 patients.37.0％ (10/27) of patients with BKV viruria developed inot BKV viremia,and sustained viremia occurred in 5 patients.The viral load in plasma was higher in patients with sustained viremia than in those with transient viremia (P＜0.05),and serum creatinine concentrations were higher when BK viremia occurred (P＜0.05).Conclusion Graft function was impaired among patients with BK viremia,and regularly monitoring BK virus in renal transplant recipients and clinical imervention based on plasma PCR results can prevent transplant kidney damage effectively.
