Objective To explore the effect of behavioral intervention on the quality of life of chronic heart congestive failure patients with urinary incontinence, to further provide basis for more effective clinical nursing measures. Methods 62 patients with chronic heart congestive failure combining urinary incontinence were divided into two groups by random digital table method, the control group and the intervention group, with 31 cases in each group. Patients in the control group received routine nursing care, while patients in the intervention group received behavioral intervention on the basis of routine care. The behavioral intervention included pelvic floor muscle training, pectineus exercise and reconstruction of micturition habits. The effect of the intervention on incontinence, quality of life and depression were observed in two groups. Results 61 patients completed the study, including 30 cases in the intervention group and 31 cases in the control group. There were no significant differences in the scores of the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICI-Q-SF), the MOS item Short Form Health Survey (SF-36) and Zung Self-rating Depression Scale ( SDS) between two groups before the intervention (P>0.05). After 6 weeks of continuous intervention, the scores of ICI-Q-SF and SDS in the intervention group were(8.69±1.94)points and (55.91±4.57) points, which were significantly lower than (11.07±2.14) points and (61.44±5.98) points of the control group (t=5.04, 3.18, P<0.01). About the SF-36, scores of physical functioning and social functioning in the intervention group were (76.77 ±10.34) points and (77.69±6.17) points, which were significantly higher than (60.39±10.07) points and (59.38±8.25) points in the control group (t=43.31, 120.36, P<0.01). Conclusions For chronic heart congestive failure patients with urinary incontinence, behavioral intervention can effectively ameliorate symptoms of urinary incontinence, improve the quality of life and relieve patients' depression, which thereby potentially promote patients′physical and mental health.

Objective To screen the mutations of MYOC gene in a Chinese primary open angle glaucoma (POAG) family from Cbengqing and investigate the relationship between the mutations in MYOC/TIGR gene and POAG.Methods In a large 4-generation glaucoma family, myocilin gene (MYOC) was screened in 39 family members, 8 of which were confirmed patients. Normal controls included 100 normal Chinese subjects.The known mutations of MYOC gene ( including G34C, C136T, G144T, G227A, C624G,G736A, C1009G, A1036G, C1081T, G1099A, G1138A, A1139C, T1430A, C1441A and C1442T) were detected by single strand conformation polymorphism(SSCP) , po]ymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis and DNA sequencing.Results G227A mutation was detected in 2 POAG patients and 1 asymptomatic patient, but not in the controls.Cl009del mutation was identified in all patients of the pedigree and an offspring member but not in the controls. No other mutations were detected.Since the C1009del mutation was revealed for the first time, a new GenBank number FJ237047 correponding to ACI62293 was applied.Conclusions The G227A mutation is a known site and there is no relationship between G227A mutation and glaucoma. But C1009del may be related to glaucoma which suggests that morbidity could be higher in the relatives of POAG than the controls.

Purpose To quantitatively evaluate the severity of brain damage in the acute phase of CO poisoning using intravoxel incoherent motion imaging.Materials and Methods MRI scans were performed in 26 patients with CO intoxication of acute stage and 18 healthy controls with matched age and gender.The difference of D value,D* value and f value in different ROIs between the poisoning and the control groups were compared,and the best cut-off values were determined.The correlation between the consciousness state and the D value as well as f value in the vulnerable area of the brain (globus pallidus) was analyzed.Results Compared with control group,the D and F value of the poisoning group were decreased in multiple ROIs,of which statistical significance was observed in the f values in the centrum semiovale,globus pallidus and thalamus,and the D values in the centrum semiovale,lateral ventricle,globus pallidus and corpus callosum splenium (P＜0.05).The best cut-off value,sensitivity and specificity were as follows:fcs=51％,77％,73％;fga=61％,77％,83％;ft=80％,85％,64％;D,=0.69×10-3 mm2/s,85％,83％;Dlv=0.65× 10-3 mm2/s,73％,89％;Dga=0.68× 10-3 mm2/s,62％,83％;Dccs=0.70× 10-3mm2/s,81％,89％.The disturbance of consciousness was positively correlated with decrease of D value and f value (rD=0.828,rf=0.745,P＜0.05).Conclusion The D and f values of intravoxel incoherent motion imaging can quantitatively evaluate the brain damage severity in acute CO poisoning.

Objective To obtain in situ pairing of the variable region genes of the immunoglobulin heavy and light chains of B cells from vitiligo patients. Methods Fifty vitiligo patients were screened by a live melanocyte enzyme-linked immunoabsorbent assay. The sera from seven patients were proved to be strongly positive. Then CD19+ B cells were isolated from the peripheral blood lymphocytes of the 7 patients, then fixed in 10% buffered formaldehyde and permeabilised by Proteinase K. The mRNA was amplified within the cells by reverse transcription-polymerase chain reaction (RT-PCR) with specific primers. The immunoglobulin VH and VL DNA assembled within the same cells using the Cre/loxP system. Nested primers were designed to amplify the known major human VH and VL gene familes. Result A unique 800bp band was obtained corresponding in size to single chain Fv fragments. Conclusion The in situ pairing of the variable region genes of the immunoglobulin heavy and light chains of B cells is obtained from vitiligo patients by in-cell PCR.

Objective To investigate the significance of the expression of serum LDH and β2-MG in predicting survival of NHL patients and there correlations with clinical parameters. Methods The serum levels of LDH and β2-MG of 429 patients with NHL were measured by rate method and immunoturbidimetry.Besides,the clinical reference of the patients such as gender,age,B symptoms,clinical stages,extranodal sites and Karnofsky evaluation were summarized and grouped.All patients' survival status were achieved via phone and letter. All statistical analyses were performed using the SPSS program for Windows (version 16.0).Results The levels of LDH and β2-MG in age,B symptom,the advanced stage,extranodal sites≥2,Karnofsky evaluation were obviously higher than their counterpart and the difference was significant (P＜0.001). The median of LDH and β2-MG lever in age group was 229 U/L,190 U/L, 2.4 mg/L,1.7 mg/L. In B symptom was 260 U/L,192 U/L,2.3 mg/L, 1.7 mg/L. In clinical stage was 252 U/L, 175 U/L, 2.5 mg/L, 1.6 mg/L. In extranodal sites group was 278 U/L,195 U/L,2.4 mg/L,1.8 mg/L.In Karnofsky evaluation group was 250 mg/L,195 mg/L,2.2 mg/L,1.8 mg/L.LDH level of invasive lymphoma was significantly higher than that of indolent ones (median 211U/L,175 U/L,P=0.002),but there were no difference in the 32-MG level (P=0.937). There were no statistical significance about LDH and β2-MG levels in gender and cell type (P＞0.05).Overall survival rates were different between the abnormal LDH group and the normal LDH group (χ2=119.029, P＜0.001).Overall survival rates were different between the elevated β2-MG group and the normal β2-MG group (χ2 =104.733,P＜0.001).Overall survival rates of the abnormal LDH/β2-MG group was significantly lower than that of normal group (x2=192.326,P＜0.001).Multivariate analysis in Cox regression showed that LDH,β2-MG,age,clinical stages, extranodal sites, Karnmofsky evaluation and aggressive were independent prognostic factors.Conclusion The level of serum LDH and β2-MG can be taken as an auxiliary clinical index to evaluate the prognosis of the NHL patients.
