To investigate the interrelationship between plasma renin activity(PRAXaldosterone (Ald),atrial natri-uretic peptide ( ANP ) and blood volume ( BV ) in adult nephrotic syndrome ( NS ) . Methods BV was assessed using 113mInCl dilution method. PRA、 Angiotensin Ⅱ (AngⅡ)、Ald、ANP were determined by radioirnmunoassay. 28 edema-tous NS patients,26 healthy controls and 18 cases of remission were involved. Results (1)During edematous period, PR, AngⅡ , Ald、 ANP were higher in NS than in controls. There was no difference of BV between NS and controls. Albumin ,PRA,AngⅡ 、Ald and ANP were not correlated with BV; (2)After remission, comparing with edematous period, Ald 、ANP deceased significantly whereas PRA、AngⅡ、Ald and total BV were not different; (3) Urine natrium excretion (UNaV) was negatively correlated with Aid. Conclusion Ald and ANP may be the major regulating factors of sodium excretion in nephrotic syndrome.

Objective: To investigate the prevalence of daily smoking among residents at ages of 15 years and older in Wuhan City, so as to provide insights into tobacco control. Methods: A total of 2 700 permanent residents at ages of 15 years and older were sampled using a multistage random sampling method in three districts of Wuhan City in July, 2019. Residents' demographics, tobacco use, secondhand smoke exposure and awareness of harmful effects of tobacco were collected using the core questionnaire of the Global Adult Tobacco Survey, and the factors affecting daily smoking were identified among residents at ages of 15 years and older using a multivariable logistic regression model. Results: A total of 2 700 questionnaires were allocated, and 2 551 valid questionnaires were recovered, with an effective recovery rate of 94.48%. The respondents included 1 272 men (49.86%) and 1 279 women (50.14%), and the proportion of daily smoking was 19.84% among the respondents, with a mean daily tobacco use of 16.6 cigarettes. Multivariable logistic regression analysis identified men (OR=66.191, 95%CI: 25.344-172.873), ages of 45 to 64 years (OR=2.586, 95%CI: 1.158-5.775), farmers (OR =8.477, 95%CI: 1.126-63.786), secondhand smoke exposure at home (OR=9.395, 95%CI: 5.401-16.340), secondhand smoke exposure in workplaces (OR=1.923, 95%CI: 1.081-3.423) and no smoking at home (OR=0.459, 95%CI: 0.277-0.763) as factors affecting daily smoking among residents at ages of 15 years and older in Wuhan City. Conclusions There is a high likelihood of daily smoking among men, the middle-aged and elderly, farmers and individuals with exposure to secondhand smoke in workplaces at ages of 15 years and older in Wuhan City. Health education pertaining to tobacco control requires to be reinforced among high-risk populations, and creation of a tobacco-free home is recommended in public places and workplaces based on the complete smoking ban.

Objective To improve the diagnosis and treatment of testicular masses associated with congenital adrenal hyperplasia(CAH).Methods A 25-year-old man presented with bilateral testicular nodules.Physical examination revealed palpable multiple nodules in the bilateral testes and epididymides as well as enlarged and hard right testis with uneven surface.Biochemical examination showed testosterone(T) of 18.7 nmol/L,17?-(OH)P＞20.0 ng/ml,positive results of rapid ACTH stimulation test and dexametha- sone suppression test.B-ultrasound demonstrated diffuse testicular lesions with nodules in parts of the bilater- al testes.Bilateral testicular nodules were biopsied,and pathological diagnosis was interstitial cell hyperplasi- a.Positive staining for?-inhibin was observed immunohistochemically.The clinical characteristics of testicular masses associated with CAH were reviewed in combination with the literature.Results Based on medical history,imaging,laboratory and pathologic examinations,the patient was diagnosed with testicular masses as- sociated with CAH.He received oral cortisol at dose of 40 mg daily for 2 weeks,and then at dose of 30 mg daily as maintenance therapy.After treatment of 8 months,B-ultrasound showed complete regression of the testicular tumors.Follow-up of 24 months showed no recurrence of the tumor.Conclusions For patient with bilateral testicular masses,endocrinological evaluation and clinical history taking are indicated to exclude testicular interstitial cell hyperplasia associated with CAH.By oral steroid replacement therapy,hormone-sen- sitive testicular masses can regress.

Objective To evaluate the effect of cytokine-induced killer cells (CIKs) as an adoptive immunotherapy option for treatment of leukemia relapse after allo-hematopoietic stem cell transplantation (allo-HSCT).Methods Two cases of infusion of donor CIKs in patients with leukemia relapse after allo-HSCT were retrospectively analyzed.Patient one relapsed 986 days (+986d) after HLA-matched unrelated donor allo-HSCT.Applications of chemotherapy only resulted in short term remission,but allo-CIKs were successfully expanded from the patient's peripheral blood mononuclear cells of donor origin.Totally five cycles of CIKs infusion were infused as an alternative of adoptive immunotherapy.Patient two had recurrent in the + 158d after HLA-matched sibling alloHSCT.At + 204d and + 294d,two cycles of CIKs which were expanded from donor peripheral blood mononuclear cells were infused.Results One cycle of CIKs was given to patient one after the application of chemotherapy to reduce the tumor burden,and the patient successively achieved complete remission.Again after additional four cycles of CIKs infusion,consistent remission was maintained during the following seven months.Patient two who had relapsed disease posttransplantation,achieved cytological complete remission after withdrawal of immunosuppressants and undergoing chemotherapy combined with G-CSF mobilized stem cell infusion.However,at + 187d,the patient suffered from side-effect of acute graft versus host disease and extramedullary infiltration.The symptoms were alleviated markedly after one cycle of CIKs infusion at + 204d.Moreover,the pain disappeared after an additional infusion at + 294d.And up to the present,the bone marrow aspiration showed complete remission while the extramedullary disease vanished.Conclusion The use of CIKs in the treatment of leukemia relapse after allogeneic bone marrow transplantation can be feasible and well tolerated.
