Objective To discuss the effect of psychological intervention on prevention of posloperation infection in patients with breast cancer .Methods 336 patients with breast cancer after operation were divided into the control group and the intervention group with 168 cases in each group.The control group received routine nursing while the intervention group Was given psychological intervention based upon routine nursing.The incidence of postopemtion infection was observed in the two groups.Results Incidenc of infection took place in 27 patients(8.04%)among 336 cases.The incidence rate infection in the control group was 12.50%,which was evidently higher than that of the intervention group(3.57%),x2=9.06,P＜0.01.The infection location and time in the intervention group was better than that of the control group.Conclusion Psychological intervention could reduce the incidence rate of posteperation infection in patients with breast cancer.

Objective To investigate the relationship between the pattern of infarct distribution on diffusion-weight imaging (DWI) and progressive movement deficits (PMD) in patients with infarct in the perforator territory of the middle cerebral artery (MCA). Methods The patients with new infarction in the perforator territory of MCA were analyzed retrospectively. PMD was defined as an increase of at least 2 points on the motor item of the National Institutes of Health Stroke Scale (NIHSS) score persisting for at least 24 hours within 5 days of stroke onset. The demographic characteristics, risk factors, clinical presentation, and distribution characteristics of the infarcts in the PMD and non-PMD groups were compared. Results A total of 64 patients were enrol ed in the study, including 38 females and 26 males, aged 67. 5 ± 10. 8 years. There were 28 patients in the PMD group and 36 in the non-PMD group. The proportion of the infarcts located in the posterior paraventricular region (67. 8% vs. 25. 0%; χ2 =11. 5, P<0. 05) of the PMD group and the mean baseline NIHSS score (6. 9 ± 1. 8 vs. 4. 3 ± 1. 2; t=2. 42, P<0. 05) were significantly higher than those of the non-PMD group. Multiple logistic regression analysis showed that the posterior paraventricular type infarcts had significantly independently correlation with PMD (odds ratio 6. 31, 95% confidence interval 2. 20-18. 0; P<0. 001). Conclusions The posterior paraventricular type infarcts on DWI can be used as a neuroimaging marker for predicting PMD in patients with infarction in the perforator artery territory of MCA.

Objective To evaluate the mid-term results of arthroscopic anterior cruciate ligament (ACL) reconstruction using Transfix technique.Methods From August 2002 to December 2003,38 patients (24 left knees and 14 right knees) with ACL ruptures underwent arthroscopic ACL reconstruction with hamstring tendon using Transfix femoral fixation and interference screws tibial fixation.There were 21 males and 17 females,aged from 19 to 48 years (average,28.4 years).The causes of injury included sports injury in 27 cases,traffic injury in 2 cases and fall injury in 2 cases,and 7 patients had no significant injury.There were 6 cases of acute injury and 32 cases of old injury.Anterior drawer test was positive in 35 cases,weak positive in 1 case and negative in 2 cases.Lachman test was positive in 37 cases,and weak positive in 1 case.The Lysholm score was used to evaluate the results.Moreover,X-rays and MRIs were used to observe the conditions of graft and bone tunnel.Results Thirty-six patients were followed up for 6.3 to 7.6 years (average,6.8 years).All patients had normal joint range of motion.The Lysholm score improved from preoperative 64.4±4.52 to postoperative 85.6±4.60,and the difference was statistically significant (P ＜ 0.05).The X-rays and MRIs showed femoral and tibial tunnel enlargement in 3 cases,femoral tunnel enlargement in 5 cases and tibial tunnel enlargement in 3 cases.No joint space narrowing was found in all patients.One patient underwent arthroscopic revision ACL reconstruction with allograft tendon using bioabsorbable interference screws fixation on both tibial and femoral sides for re-rupture of ACL 4 years after operation due to trauma.Conclusion Arthroscopic ACL reconstruction with hamstring tendon using Transfix femoral fixation and interference screws tibial fixation is an effective method,which can provide satisfactory joint range of motion and stability.

[Objective]To investigate the pharmacological mechanism of montelukast in the inhibition of inflammation.[Meth-ods]Respiratory syncytial virus-infected human bronchial epithelial cell(16HBEC)inflammatory cell model was established,and mRNA and protein expressions of Nuclear factor NF-E2 related factor(Nrf2),heme oxygenase(HO-1),quinone oxidoreductase (NQO-1),and glutathione transferase (GST) were determined by qPCR and Western-blot ,and production of cellular reactive oxygen species(ROS)was measured by DCFH-DA fluorescent probe method. Nrf2 siRNA was further synthesized to reduce the expression of Nrf2 ,to investigate the chang of inflammatory index.[Results]Montelukast significantly reduced the expressions of inflammatory cytokines IL-6,TNF-α,and IL-1β(P<0.05)on respiratory syncytial virus-infected 16HBEC,and the ROS level in inflammatory cell model was decreased(P<0.05),increased the mRNA and protein expressions of Nrf2,HO-1,NQO-1 and GST (P < 0.05),with a more significant effect at higher dose. After the down-regulation of Nrf2,the expressions of inflammatory cyto-kines IL-6,TNF-α,and IL-1βwere increased(P<0.05),and ROS level was significantly increased(P<0.05),mRNA and pro-tein expressions of Nrf2,HO-1,NQO-1 and GST were decreased(P<0.05).[Conclusion]Montelukast inhibits the inflammation of human bronchial epithelial cells infected by respiratory syncytial virus (RSV),and the potential mechanism may involve its ef-fect on the Nrf2/ARE signaling pathway.

[Objective] To investigate the changes of CD4~+ CD25~+ regulatory T cells (Tr) in peripheral blood and their relation with their body mass index (BMI) of children with acute attack asthma. [Methods] Peripheral blood was obtained from 70 children with acute attack asthma, 30 remission children, and 50 normal control children. Then 70 children with acute attack asthma, were divided by normal weight group (40 cases) and overweight group (30 cases). The levels of CD4~+CD25~+Tr of the patients were tested by flow cytometry (FCM), and their BMI were calculated. [ Results] The levels of CD4~+ CD25~+ Tr [(6.17± 1.72)%] in acute attack group were lower than that in remission group [(7.56±1.48)%] or that in the control group [(7.13± 1.48)%] (P<0.05), but no difference between that in the remission and that in the control (P>0.05). The CD4~+CD25~+Tr of asthmatic children with normal weight [(6.34±1.71)%] was higher than that of asthmatic children with overweight [(4.74±1.20)%] (P<0.05). There was a remarkably negative correlation between the level of CD4~+ CD25~+ Tr of asthmatic children [(6.17±1.72)%] and the BMI (16.00±2.14) (r_p=-0.814, P<0.05). [Conclusion] The levels of CD4~+ CD25~+Tr are remarkable decrease in attack asthmatic children, and more decrease in overweight patients. There is remarkably negative correlation between the levels of CD4~+CD25~+ Tr in peripheral blood of attack asthmatic children and their BMI.

Objective To investigate the expression and clinical significance of miR-125b in patients before and after treatment of acute myeloid leukemia (AML) with different types.Methods The levels of miR-125b were measured by using real-time fluorescence quantification PCR (qRT-PCR) in 65 AML patients (all AML samples from the Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University,and the control samples isolated from cord blood which were obtained after normal full-term delivery of babies) before and after treatment,and then the relationship between the levels of miR-125b and patients＇ sex,age,peripheral blood cells,type clinically,relapse and therapeutic effect were analyzed.Results Of newly diagnosed AML patients and the control samples,miR-125b positive rate was 100％.The miR-125b expression levels in the control group was 1.50,and its expression in AML was 11.06,and the difference was significant (P =0.036 6).In complete remission (CR) group of acute promyelocytic leukemia (M3),the expression of miR-125b after induction therapy was significantly reduced,and CR rate of miR-125b decreased group was 91.3％,while that of the increased group was 50.0％,and the difference was significant (P =0.042 6).The miR-125 b expression level was decreased from 29.7 ± 4.9 to 19.2 ± 6.0 after chemotherapy,and the difference was significant (P ＜ 0.036 6).In non-M3 AML,CR rate of miR-125 b decreased group was 86.7 ％,while that of the increase group was 42.1％,and the difference was significant (P =0.021 5).There was no correlation between miR-125b expression and patients＇ gender,age and peripheral blood cells.Conclusions The differences in expression of miR-125b is very important in disease occurrence and progress.Using qRT-PCR to dynamically detect the expression of miR-125b dynamically in AML patients before and after therapy may predict outcome more precisely and has the potentials as an effective biomarker in determining prognosis,monitoring the risk of recurrence,and guiding the treatment.

Objective To investigate the preventive effects of curcumin for status epilepticus(SE) induced by lithium chloride-pilocarpine.Methods Totally 45 Sprague-Dawley(SD) rats were randomly divided into three groups: preventive group(n=15),non-preventive group(n=15),and control group(n=15).The latency peroid and incidence of SE were recorded.The surviving neurons were stained by using nissl staining,and the programme death cells were detected by using terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) in hippocampal CA3.Results The SE incidence of preventive group was 66.7%,which was significantly lower than that of non-preventive group(P0.05).Conclusion Pretreatment of curcumin can prevent the SE induced by lithium chloride-pilocarpine and the pretreatment can not protect the neuron.
