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 investigate the effect of Brocho-Vaxom in curing chronic pulmonary heart disease and the influence of patient's immunity.Methods 58 patients with chronic pulmonary heart disease were randomly divided into two equal groups.Each patient of treatment group took a Brocho-Vaxom capsule(7mg/cap) every.The respiratory tract infection times and duration were observed.The serum IgA,IgG,IgM level were tested by fast immunonephelometry.The sub-type lymphocyte was tested by SP,and the NK cell's activity was tested by MTT.Results The infection time obviously declined in treatment group which the average was (2.5?1.8) in five months as compared with that in the controlled group(P

Objective To probe into the relationship between social support, coping styles and resiliency of nurses in surgery department. Methods A total of 192 surgical nurses were selected from a general tertiary hospital in Fuzhou on random cluster sampling basis. The following measures were used to collect data:the Chinese version of Mental Resilience Scale, the Simple Coping Style Questionnaire and the Social Support Rating Scale. Results The resilience score of surgical nurses was (58.41 ± 12.86) points. Also, resilience had positive and significant correlation with positive coping styles, social support, objective support , subjective support and support utilization degree (more specifically r = 0.629, P <0.01 and r = 0.334, P < 0.01, r = 0.242, P < 0.01 and r = 0.312, P < 0.01 and r = 0.156, P < 0.05). Conclusions The overall level of resiliency in surgical nurses was undesirable, however effective problem-based coping skills and adequate social support may help the group improve resilience and to qualify for better nursing services.

Objective:To investigate the relationship among happiness, resilience, optimistic intelligence quotient and perceived social support in patients with advanced gynecological cancer.Methods:A total of 269 patients with advanced gynecological cancer from January 2018 to January 2019 in three top three hospitals in Shanghai were selected as subjects by convenient sampling.The basic information questionnaire, Memorial University of New-foundland scale of happiness, Connor-Davidson Resilience Scale simplified Chinese version, Optimistic Intelligence Quotient Questionnaire and Perceived Social Support Scale were used to investigate.Results:The score of happiness was (32.45±6.37), the score of resilience was (30.64±8.78),the score of optimistic intelligence quotient was (62.74±12.49) and the score of perceived social support was (68.14±4.25) in patients with advanced gynecological cancer. Linear regression equation analysis showed that happiness and optimistic intelligence quotient × happiness had significant predictive effect on resilience ( β values were 0.547, 0.016, P < 0.05), optimistic intelligence quotient had no significant predictive effect on resilience ( P>0.05), and optimistic intelligence quotient, happiness, resilience, optimistic intelligence quotient×happiness had significant predictive effect on perceived social support ( β values were 0.015-0.251, P<0.01). Happiness could regulate the direct path and the first half of the mediating effect of resilience between perceived social support and optimistic intelligence quotient. According to Johnson-Neyman's analysis, the boundary value of the moderating effect of happiness between optimistic intelligence quotient and resilience was 26.19, and the boundary value of the moderating effect of happiness between optimistic intelligence quotient and perceived social support was 22.08. Conclusions:There is a positive correlation between optimistic intelligence quotient and perceived social support in patients with advanced gynecological cancer. Resilience can play a significant mediating role between optimistic intelligence quotient and perceived social support under the regulation of happiness, which can provide corresponding psychological intervention for patients with advanced gynecological cancer.

Objective To investigate the difference between two substrains,5-8F and 6-10B,of nasopharyngeal carcinoma cell line SUNE1on expressing metastasis-associated gene 1 (MTA1),and evaluate the silencing effect of lentivirus-mediated RNA interference (RNAi) on MTA1 in human nasopharyngeal carcinoma cell line.Methods The differential expression of MTA1 mRNA and MTA1 protein in 5-8F and 6-10B cell lines were detected by real time PCR and Western blotting respectively.Short interference RNA (siRNA) fragment targeting MTA1 gene was designed using online databases and software.A specific RNAi lentiviral vector targeting human MTA1 gene was constructed and transfected into nasopharyngeal carcinoma cell line 5-8F.Real time PCR and Western blotting were performed to detect the expressive changes in MTA1 mRNA and MTA1 protein in the transfected 5-8F cells respectively.Results Compared with cell line 6-10B,the expressions of MTA1 mRNA and MTA1 protein were higher in 5-8F cell line.Sequence analysis validated the correct insert of siRNA targeting MTA1 gene into the lentiviral vector.Real time PCR and Western blotting results showed that the expressions of MTA1 mRNA and MTA1 protein in 5-8F cell lines were down-regulated significantly after siRNA transfection.Conclusions MTA1 may promote the malignant transformation and enhance the metastatic potential of nasopharyngeal carcinoma cell lines.The expression of MTA1 in 5-8F cells can be inhibited effectively by MTA1-specific siRNA expression lentiviral vector,which provides a valuable tool for investigating the role of MTA1 gene in the carcinogenesis and progression of nasopharyngeal carcinoma.

Objective To explore the methods of identifying factitious/fraudulent disorders (M?n-chausen syndrome), enhancing the understanding of their predisposing factors, clinical features, and underlying psychopathology. Method After a final diagnosis of factitious fever was made, data of 4 patients presenting with a puzzling fever of unknown origin were analyzed and compared with those of other cases reported in the English literature. Result It was confirmed that the elevated temperature recorded in the clinical charts of the 4 patients was faked by manipulating of the thermometer. Conclusion These 4 cases show the existence of factitious/fraudulent disorders in China, possibly related to an abnormal psychology, but the tricks employed by the patients are relatively simple compared with those used abroad.

Objective To explore the diagnostic value of ultrasound-guided aspiration biopsy in patients with unexplained refractory ascites.Methods The data of 25 cases of unexplained refractory ascites were retrospectively analyzed.For all the cases the diagnosis was based on the examination of contrast enhanced CT or ultrasound.Ultrasound-guided aspiration biopsy of locally thickened peritoneum or ti- ny masses in ascites was performed.Reults Ultrosonographic image of all cases was as follows.10 cases,with locally thickened peritone- um,were isoechoic or hypoechioc.In 2 of 10 cases contrast enhanced ultrasound examination was done,and the images were characterized by an obvious enhancement in arterial phase and quick wash-out in veinous phase.In 7 cases there was irregularly thickened peritoneum, accompanied by adhesion and caking of the omentum.Cystic formation in ascites or in peritoneum was found in 5 cases.Solid mass in asci- tes was found in 2 cases,and splenomegaly and enlarged pancreas were found in 1 case.Ultrasound-gnided aspiration biopsy was perfomed in all the patients.Among them 4 patients were operated on later.Histopathologic examination showed malignency in 20 patients.Among them,malignant peritoneal mesothelioma accoumted for 6 cases,pancreatic cystoadenoma in 2,mestastic adenocarcinoma in 9,malignant schwannoma in 1,lymphoma in 1,and histiocytoma in 1 patient.In the other 5 cases the lesion was benign,and it was verified by follow- up for about 6 months.Among them there were 3 cases of tuberculosis,1 case of inflammatory disease and 1 case of retroperitonesl fibro- sis.Conclusion Ultrasound-guided aspiration biopsy is valuable in the diagnosis of locally thickened peritoneum and tiny mass in ascitic fluid,and is valuable for diagnosis of unexplained refractory ascites.

Objective To study the expression levels of inducible costimulator (ICOS) on CD4+ T cells in peripheral blood in patients with chronic hepatitis B and its change after treated with interferon.Methods All 56 patients were divided into two groups (interferon group has 28 cases,lamivudine group has 28 cases),and interferon group treated by PEG-IFN-α 2a,lamivudine group treated by lamivudine,respectively.There were 20 healthy individuals as control group.The levels of ICOS on CD4+ T cells of patients with chronic hepatitis B were kinetically detected by flow cytometry.The copies of HBV DNA in sera were dynamically detected by real-time PCR.Results The levels of ICOS on CD4+ T cells in patients with chronic hepatitis B was higher than that of normal controls(P＜0.001 ).However,the expressions of ICOS on CD4+ T cells in patients could be deduced by PEG-IFN-α 2a and obviously decreased after treatment.There was significant difference between interferon group and lamivudine group (P＜0.05 in 24 weeks,and P＜0.01 in 48 weeks).After treatment,the change values of ICOS in interferon group was positively correlated with the change copies of HBV DNA (r =0.972,P＜0.001 ).However,the change values mentioned above that did not find correlation in lamivudine group(r=-0.101,P=0.608).Conclusion The study shows the patients with chronic hepatitis B have disordered in cellular immunity and increased with the expression of ICOS on CD4+ T cells.PEG-IFN-α 2a could decrease the expression of ICOS on CD4+ T cells in patients,and correct the Th2 type immune polarization to some extent,and that plays a positive role in antiHBV.

Objective To investigate the underlying mutation in a late-onset Chinese patient with classic Bartter syndrome. Methods The mutation analysis of CLCNKB gene was performed by the PCR direct sequencing. The patient's parents and siblings were studied as well. Fifty normal volunteers were analyzed as control group. Results The heterozygous deletion mutation cDNA 753delG and heterozygous missense mutation G433E were detected in the patient. Her father was found to carry heterozygous G433E and her mother to carry cDNA 753delG mutation respectively. Her brother carried heterozygous G433E and her sister was normal. Conclusions Two mutations of the CLCNKB gene in this Chinese patient with late-onset classic Bartter syndrome are identified. The cDNA 753delG mutation has not been reported previously.
