PET/CT is often used in the management of patients with lymphoma ,and have been recom-mended for the staging and response assessment in diffuse large B -cell lymphoma and Hodgkin ,slymphoma .Al-though follicular lymphoma is almost always 18 F-fluorodeoxyglucose avid ,PET/CT is not routinely used in the clinical practice of follicular lymphoma .But there is a growing body of literature supporting the use of PET /CT in follicular lymphoma.Therefore,on the application of PET/CT in follicular lymphoma ,we review the recent litera-tures in this paper .

Objective To evaluate the inflammatory response in the airway of healthy rats following exposure to motor vehicle exhaust. Methods Sixty healthy SD rats(30 males and 30 females,aged 6 weeks) were randomly divided into 6 groups. The rats in the exposed groups were placed by the main traffic road and those in the control group were placed in the normal laboratory environment. The bronchoalveolar lavage fluid(BALF) was analyzed on the 14th,30th and 90th day of exposure .WBC,NO,TNF-?,and IL-8 in BALF of the rats in each group were tested. Results The NO content [(9.75?4.78) ?mol/L] in BALF of the rats in the group exposed for 30 days was obviously higher than that in the control group [(4.40?1.45) ?mol/L],but there was no any obvious difference between the two groups in terms of the content of TNF-? and IL-8 in BALF. Conclusion This study demonstrates that exposure to vehicle exhaust can induce inflammatory response in healthy rats,the on-the-spot experiment on animal exposure can be used to observe early respiratory tract inflammation and 30 days of exposure is the sensitive period for the change of the inflammatory indicators.

Objective To investigate the clinical characteristics,diagnosis,therapy and maternal and perinatal prognosis of generalized pustular psoriasis of pregnancy.Methods Clinical data for seven inpatients with generalized pustular psoriasis of pregnancy were retrospectively analyzed from January 1,2005 to December 31,2012.Results Three patients had family history of psoriasis and five had previous history of psoriasis.All skin lesions were large patches of erythema,with needlepoint to miliary size pustules and scales.Two patients had oral involvement and three had nail involvement.Biopsy and bacterial culture were performed on five patients,in whom histopathological changes of pustular psoriasis were found,and bacterial culture was negative except in one patient.Among the patients,four had confirmed cause of disease; six patients were complicated with fever; four had increased leukocytes; seven had elevated neutrophils and C-reactive protein;five had increased total protein; and six had increased albumin.The disease was diagnosed according to the clinical manifestations and laboratory tests.Comprehensive treatment with glucocorticosteroids,antibiotics and local treatment were performed.Four patients had live births,and three patients underwent odinopoeia.Two babies were healthy,one had died,and another had varus foot deformity.Three patients had pustular relapse after labor.Conclusions Fetal-placental functions of patients with generalized pustular psoriasis of pregnancy should be monitored closely.Early diagnosis,treatment and termination of pregnancy can improve the maternal and perinatal prognosis.

Thyroid dysfunction is particularly common during pregnancy , which may affect pregnancy outcomes , and harm maternal and child health.Since release of 2011 pregnancy thyroid-stimulating hormont(TSH) diag-nostic guidelines by American Thyroid Association (ATA).In 2012,Endocrinology branch and Perinatal Medi-cine Branch of the Chinese Medical Association jointly issued the “pregnancy and postpartum thyroid disease di-agnosis and treatment guidelines”, it is important that each laboratory has its own reference interval for diagnosing thyroid disorders in pregnancy.This article discussed trimester-specific thyroid hormone reference of the area in where the auther live.

Background Idiopathic macular epiretinal membrane (IMEM) combined with age-related cataract (ARC)is a common eye disease and the primary managing approach is the combination of phacoemulsification,intraocular lens (IOL) implantation and vitrectomy.However,whether the ocular length measured by IOL Master is accurate for the calculation of IOL refraction in the eye with IMEM remains unclear.Objective The aim of this study was to evaluate the refractive outcomes of combination surgery of phacoemulsification,IOL implantation and vitrectomy in IMEM eyes.Methods A prospective cohort study was designed.Forty-two eyes of 42 patients with IMEM combined with ARC (IMEM+ARC group) were enrolled in Peking University People's Hospital and the combination of phacoemulsification,IOL implantation and vitrectomy was performed from September 2010 to August 2011,and 47 eyes of 47 patients with ARC were included for the phacoemulsification combined with IOL implantation in the corresponding period (ARC group) under the approval of Ethic Committee of Peking University People's Hospital and informed consent of the patients.Ocular length and corneal curvature were measured using IOL Master,and the expected IOL diopter was calculated with SRK-T formula.Regular eye examination and medical optometry were performed 1 month and 3 months after operation to obtain the actual diopter and the refractive error.The outcomes were compared between the two groups.The correlations of refractive error with change of fovea thickness were evaluated after operation in the IMEM+ARC group.Results There were no statistically significant differences in the age,ocular length and corneal curvature between the two groups before operation (P =0.863,0.704,0.770).The visual acuity was improved 3 months after operation in comparison with before operation in both groups (P=0.001,0.000).The negative diopters were obviously higher 1 month and 3 months after operation than those before operation in both groups (all at P＜0.001),but no significant difference was seen between the IMEM+ ARC group and ARC group (Fgroup =0.417,P =0.520).The diopter deviations 1 month and 3 months after operation were (-0.727±0.666)D and (-0.628±0.627)D in the IMEM+ARC group,and those in the ARC group were (-0.664±0.644) D and (-0.642±0.550) D,showing insignificant differences between the two groups (Fgroup =0.036,P =0.849 ; Ftime =1.523,P =0.221).In IMEM + ARC group,the macular fovea thickness was (474.89 ± 135.76)μm in preoperation,and the shift values of macular fovea thickness were (-83.84 ±91.12)μm and (-158.53±113.03) μm in postoperative 1 month and 3 months.No positive correlations were presented between the diopter deviations and change of fovea thickness 1 month and 3 months after operation in the IMEM+ARC group (r=0.200,P =0.229 ; r =0.065,P =0.698).Conclusions Myopia shift after operation is similar in the IMEM combined with ARC patients to the only ARC patients,suggesting that the ocular length and corneal curvature measured by IOL Master is not affected by epiretinal membrane.

Objective To investigate the value of perfusion CT in the evaluation of neoadjuvant chemotherapy in locally advanced squamous cell carcinoma.Methods Sixty-seven patients with Ib2-IIb squamous cell carcinoma of the cervix underwent CT perfusion imaging before neoadjuvant chemotherapy to measure blood flow (BF),blood volume (BV),peak time (MTT),permeability sur-face (PMB),perfusion time to peak (TTP)and MIP(HU);and underwent routine enhancement CT after the two course of neoadju-vant chemotherapy treatment to measure tumor size,and evaluate the therapeutic effect.Results Among 67 patients,48 patents were effective (2 completely remission and 46 partial remission),and 1 9 patients were ineffective (1 5 stable and 4 progressed),with the overall response rate of 71.6%.The differences of PMB and BV value between effective and ineffective group were statistically significant before neoadjuvant chemotherapy (P <0.001).The BF,MTT,TTP value were no significant difference between effec-tive and ineffective group before neoadjuvant chemotherapy (P >0.05).The BV and PMB value were relatively higher in the patients with effective chemotherapy.Conclusion CT perfusion imaging could measure the BV and PMB value of the tumor before neoadju-vant chemotherapy to provide the basis for treatment selection.

Objective To determine whether tChoI and ADC and their changes could be applied to predict pathologic response be-fore,during and after NAC of locally advanced breast.To assess the diagnostic performance of each parameter.Methods The tChoI and ADC and their changes in 22 women who underwent MRI before,during and after the NAC were analyzed prospectively.All pa-tients were divided into major histological response group and non-major histological response group by methods of Miller and Payne system according to the final pathologic response.Pre-and post-treatment measurements and changes in tChoI and ADC values in MHR versus NMHR were analyzed using Mann-Whitney U test.ROC curve analysis was performed to assess the diagnostic per-formance of each parameter and also to identify which parameter could be used to predict the pathologic response to NAC and find the optimal cut off value for MHR prediction.Results After NAC,14 patients showed MHR and 8 showed NMHR.After NAC,all the parameters and their changes were significantly different between the MHR and NMHR groups,the change rate of all parameters af-ter NAC can actively diagnosis the MHR according ROC(AUC>0.5).Using 0.913 ×10 -3 mm2/s of ADCmin after NAC as the cut off value,prediction of MHR with sensitivity and specificity was 85.7% and 100%,respectively.Using 81.25% of the change rate of tCho I after NAC as the cut off value,prediction of MHR with sensitivity and specificity was 71.4% and 100%,respectively(AUC=0.881,P =0.008).The △ADCmin 2% and △tChoI2% are better than △ADCmean 2%.Conclusion Application of 3D 1 H-MRS and DWI can predict pathologic response and may provide more detailed and accurate evidence for subsequent treatment.
