Objective To evaluate the clinical value of 18F-FDG PET-CT in monitoring response to therapy in patients with follicular lymphoma (FL) staging Ⅲ-Ⅳ.Methods The clinical data of 20 patients with FL were analyzed retrospectively.All patients underwent PET-CT at three times:baseline,after 3-4 cycles of chemotherapy,and end of treatment.Kaplan-Meier method was used to analyze the survival of patients.Results 14 patients achieved CR at the interim PET-CT,all patients achieved CR at post therapy PET-CT:all patients were alive with no evidence of disease in the follow-up.2 patiens achieved PR at the interim PET-CT,and 1 patient achieved CR,and 1 patient was PD,at post therapy PET-CT,all patients were relapsed in the follow-up.4 patients achieved PD,and all patients were changed the chemotherapy plan.At post therapy PET-CT,2 patients achieved CR,1 patient achieved PR,and 1 patient was PD,1 patient was no evidence of disease,2 patients were relapsed,and another was died in the follow-up.The negative predictive values (NPV) of the interim and the post therapy PET-CT were 100 ％ (14/14),88.2 ％ (15/17) respectively.The interim PET-CT was no significantly correlated with PFS (P =0.135),while the post therapy PET-CT was significantly correlated with PFS (P =0.0006).Conclusion 18F-FDG PET-CT is useful to monitor response to chemotherapy in patients with FL staging Ⅲ-Ⅳ,and set personalized treatment plan.

Objective To investigate the clinical value of 18F-FDG PET/CT in staging,therapeutic response evaluation,relapse early detection and prognostic prediction of follicular lymphoma (FL).Methods Twenty-eight patients (12 males,16 females; average age 57 (36-82) years) with pathologically confirmed FL from December 2005 to January 2013 were enrolled.All patients underwent 18F-FDG PET/CT before treatment.The SUVmax of different staging groups,different pathological grade groups (high:3a+3b; low:1+2) was compared.Seventeen of 28 patients underwent PET/CT after chemotherapy and received phone follow-up (10-88 months) to monitor the progress of treatment.Survival difference was analyzed.Mann-Whitney u test,Wilcoxon signed-rank test and Kaplan-Meier survival analysis were used for data analysis.Results (1) The initial clinical staging without 18F-FDG PET/CT based on Ann Arbor standard changed in 4 cases (up-staging in 3 cases,down-staging in 1 case) after the PET/CT scan.The 18F-FDG uptake (SUVmax) in patients of stage Ⅰ/Ⅱ and stage Ⅲ/Ⅳ was 10.1±3.2 and 11.5±4.9,respectively (Z=-0.619,P＞0.05).The SUVmax in patients of the low grade group (6.9±3.6,n=15) was significantly lower than that of the high grade group (12.4±5.6,n=13) (Z=-3.706,P＜0.01).(2) 17 patients underwent PET/CT scan both before and after chemotherapy,the pre-treatment SUVmax and post-treatment SUVmax were significantly different in CR+PR group (10.8±5.1 vs 3.4±2.3; Z=-2.312,P＜0.05),while there was no significant difference in SD+PD group (11.2±6.9 vs 7.8±3.3; Z=-1.153,P＞0.05).There was a significant difference in the median progress-free survival time between the CR+PR group and the SD+PD group (48 months vs 26 months; x2 =4.207,P＜0.05).Conclusion 18F-FDG PET/CT has an advantage in clinical staging,therapeutic evaluation,relapse monitoring and prognosis predicting of FL.

Purpose To investigate the role of PTEN in podocyte injury in patients with diabetic nephropathy ( DN) . Methods Uri-nary samples from 30 patients with DN and 10 healthy volunteers were collected to detect the level of PCX by ELISA. Renal biopsies were reviewed to observe the morphological changes. All patients with DN were divided into three groups by glomerular lesion. The ex-pression of p-Akt and PTEN in glomeruli was detected by immunohistochemistry. Results The levels of PCX in the urine were signifi-cantly higher in patients with DN compared with those in healthy volunteers, and gradually increased along with glomerular lesion aggra-vating. The expression of p-Akt and PTEN increased in patients with DN compared with healthy volunteers. Although the expression of p-Akt and PTEN decreased with the aggravation of glomerular lesion, they were still higher than that in volunteers. There were obvious-ly positive correlation between the level of PCX and 24-h urinary protein and negative correlation between the level of PCX and the ex-pression level of p-Akt and PTEN. Conclusion PTEN down-regulation may be associated with podocyte injury in DN, which may be associated with the phosphorylation of Akt.

Objective To observe the clinical efficacy of butylphthalide soft capsules for treatment of acute cerebral infarction and its effect on the neurological function and inflammatory reaction of patients.Methods A total of 100 patients with acute cerebral infarction in the First Hospital of Zhangjiakou City and the Third Hospital Affiliated to Hebei North University from January 2016 to October 2016 were selected and divided into control group (n =50) and treatment group (n =50) according to the treatment protocols.The patients in the control group were given anti-platelet aggregation,statins,and other routine treatment;based on this,the patients in treatment group were orally administrated with butylphthalide soft capsules.The elbow venous blood of patients in the two groups was collected and the C reactive protein(CRP),interleukin-6 (IL-6) levels,the platelet aggregation rate were detected.The change of National Institute of Health stroke scale(NIHSS) score of patients after four weeks treatment was compared between the two groups.The recovery of neurological function of patients in the two groups was evaluated by modified Rankin grading after three months treatment.Results There was no statistic difference in the CRP,IL-6 levels and platelet aggregation rate before treatment between the two groups (P ＞ 0.05).The CRP,IL-6 levels and platelet aggregation rate of patients in the two groups after one week treatment were significantly lower than those before treatment (P ＜ 0.05);and the CRP,IL-6 levels and platelet aggregation rate of patients in the treatment group were significantly lower than those in the control group after one week treatment (P ＜ 0.05).The NIHSS score of patients in the treatment group was significantly lower than that in the control group after four weeks treatment (P ＜ 0.05);the Rankin score of patients in the treatment group was significantly lower than that in the control group after three months treatment (P ＜ 0.05).The total effective rate of patients in the treatment group was significantly higher than that in the control group (x2 =13.22,P ＜ 0.05).Conclusion Butylphthalide soft capsules can significantly reduce the inflammatory reaction in patients with acute cerebral infarction,improve and recover the neurologic impairment;and its curative effect is remarkable.

Objective To study comparison of central line-associated bloodstream infection (CLABSI)with different catheterization methods of neonates and the comparison of each type of catheter and the general condition of neonates and the influence of catheter time on CLABSI. Methods A total of 797 neonates with umbilical venous catheter(UVC)or PICC were studied from August 2014 to September 2016,among them,278 were adopted with UVC(UVC group),262 were adopted with PICC(PICC group), and 263 were adopted with UVC and PICC catheter(combination group).Respectively recorded all the neonates′general situation,analized the differences of each group,and recorded each group of 4 days of CLABSI number, and evaluated the 10th day of CLABI progress of each group. Results There were significant differences among 3 groups of newborns in gestational weeks, birth weight, the number of respiratory distress syndrome at birth, the number of sepsis at birth, the number of cesarean delivery babies and the number of deaths were statistically significant (F=5.998, 4.943, χ2=5.160-8.970, all P <0.05). The incidence of CABSI in fourth days was 1.1% (3/278) in UVC group, 1.9%(5/262) in PICC group,and 3.0%(8/263)in combination group.On the tenth day,the incidence of CABSI was 5.4%(15/278)in UVC group,2.7%(7/262)in PICC group,and 5.1%(10/196)in combination group removing UVC, while 10.4% (7/67) in combination group without removing UVC. The PICC group and the combination group removing UVC had no significant difference in CABSI infection(P>0.05)and in UVC group,the incidence rate increased significantly (χ2=2.85, P < 0.05), combination group without removing UVC increased significantly in patients with CABSI infection and the difference was statistically significant(χ2=6.31,P<0.01). Conclusions UVC group had more risk of CABSI compared with PICC,we can choose UVC for short term,and PICC catheter for long term.

Objective To evaluate the effect of weight-bearing alignment training (WBAT) in correcting anterior pelvic tilt in children with cerebral palsy.Methods Twenty-seven children with cerebral palsy and anterior pelvic tilt were recruited and randonly assigned to a WBAT group,a strengthening group and a standing group,each of 9.In addition to routine medication and rehabilitation training,the 3 groups received WBAT,strengthening training or standing training respectively for 20 minutes a day,5 times a week for 4 weeks.Before and immediately after the treatment,the subjects' anterior superior iliac spine-posterior superior iliac spine angles (ASIS-PSIS angles) were assessed along with their anterior-posterior angles (A-P angles) and distances in a 1-minute walk test.Results The WBAT group showed significant improvement in their average ASIS-PSIS angle (to 18.61 ± 3.13°),A-P angle (to 23.31±3.81°) and the distance in the 1-minute walk test after the treatment.The standing group had significant progress in improving their A-P angles (to 24.48±4.33°),and the strengthening group had significant improvement in the distance walked in the 1-minute walk test.The average improvements in the ASIS-PSIS angle and walk distance in the WBAT group were significantly better than in the other 2 groups.Conclusion WBAT is superior to strengthening and standing training in improving the ASIS-PSIS angle,A-P angle and walking ability of children with cerebral palsy and anterior pelvic tilt.
