Objective To study the relationship of T, B and NK lymphocytes with the pathogenesis of chronic urticaria. Methods Flow cytometry was applied to assess the proportion of T, B and NK lymphocyte subgroups in the peripheral blood of 51 patients with chronic urticaria and 30 sex and age-matched human controls. The CD4:CD8 ratio was calculated. Moreover, the symptoms, disease course and response to antihistamines of these patients were evaluated by one physician. Results The percentage of CD8+ T and NK cells, CD4:CD8 ratio were (27.20±8.22)%, (21.20±10.84)% and 1.48±0.62, respectively, in these patients,(29.9±3.74)%, (17.5±3.56)%, 1.24±0.27, respectively, in the controls; the differences were significant between the two groups (all P＜0.05). Decreased levels of CD3+ T cells, CD8+ T cells and B cells were noted in patients resistant to antihistamines compared with those responsive to antihistamines[(61.81±11.70)% vs (75.74±2.36)%, (24.00±7.79)% vs (34.22±9.30)%, (10.78±2.07)% vs (15.25±4.10)%, P＜0.05, 0.01, 0.05, respectively)], while the CD4:CD8 ratio and percentage of NK cells were increased in antihistamine-resistant patients compared to those in antihistamine-sensitive patients [1.67±0.76 vs 1.17±0.41, (28.61±12.62)% vs (12.78±6.02)%, both P＜0.01 ]. In these patients with chronic urticaria, the percentages of CD3+ T and CD8+ T cells were negatively correlated with the symptom scores (R = -0.31, -0.28, respectively, both P＜0.05 ), while the percentage of B cells was positively correlated with the symptom scores and disease course (R = 0.53, 0.55, respectively, both P＜0.01 ). Conclusions There is an abnormality in the proportion of T, B and NK lymphocyte subgroups in patients with chronic urticaria,which indicates that humoral immunity may be involved in the pathogenesis of chronic urticaria and the mechanism for responsiveness to antihistamine.

Objective To analyze clinical characteristics of premenopausal and postmenopausal female patients with kidney stones.Methods The clinical data of 1 194 female adults with kidney stones from December 2004 to December 2014 were analyzed retrospectively.The incidence of kidney stones in different age groups was analyzed firstly.The post-hysterectomy patients or those taking estrogen for breast cancer were excluded, and then 1 166 patients were enrolled.The patients were divided into premenopausal group (464 cases, 39.8％) and postmenopausal group (702 cases, 60.2％), and clinic features of different groups were evaluated.Results The peak age of female patients with kidney stones is between 50 and 59 years old.There were 105 (22.6％) patients in premenopausal group and 204 (29.1％) patients in postmenopausal group complicated with urinary infection.Fifty-eight (12.5％) patients had genitonrinary malformations such as horseshoe kidney, medullary sponge kidney, ectopic kidney, duplex kidney or pyeloplasty for ureteropelvic junction (UPJ) stricture in premenopausal group, as well as 36 (5.1％) in postmenopausal group.Twenty patients (4.3％) had renal insufficiency in premenopausal group, and 66 (9.4％) in postmenopausal group.These differences were statistically significant (P ＜ 0.05).The patients complicated with hydronephrosis (251 vs.346) and ureteral calculi (63 vs.110) of two groups were not significant different (P ＞ 0.05).Multiple factors Logistic analysis indicated that age and urinary infection were statistically significant factors in the occurrence of renal insufficiency (OR =1.037,1.772, P ＜ 0.05).Conclusions The occurrence of genitourinary malformations was higher among premenopausal female patients with kidney stones, while urinary infection and renal insufficiency were more common for postmenopausal patients.Age and urinary infection were the independent factors for the occurrence of renal insufficiency.

OBJECTIVE:To investigate the effects of hyperbaric oxygen combined with flupentixol and melitracen on depres-sion improvement,extremity motor function and ability of daily living and activity in patients with post-stroke depression (PSD). METHODS:60 PSD patients were divided into control group and observation group according to random number table,with 30 cases in each group. Both groups received routine clinical treatment,comprehensive rehabilitation therapy and psychotherapy. The control group was additionally given Flupentixol and melitracen tablets,orally,one tablet each time,in the morning;3 days later, one tablet each time,in the morning and noon,for 4 weeks. Other anti-depressive agents were not given during treatment. Observa-tion group was additionally given hyperbaric oxygen,0.12 MPa,for 90 min,qd,5 times a week,for 4 weeks,on the basis of control group. Depression degree [Hamilton depression scale (HAMD) and Self-rating depression scale(SDS)],extremity motor function [Fugl-Mayer motor function assessment (FMA)] and ability of daily living and activity [modified Barthel index (MBI)] were scored in 2 groups before and after treatment,and ADR was observed. RESULTS:After 4 weeks of treatment,HAMD and SDS of 2 groups were decreased significantly compared to before treatment,while FMA and MBI were increased significantly;the improvement of observation group was significantly better than that of control group,with statistical significance(P<0.05). No ob-vious ADR was found in 2 groups. CONCLUSIONS:Hyperbaric oxygen combined with flupentixol and melitracen can effectively improve PSD,relieve negative emotion and improve extremity motor function and ability of daily living and activity.

Objective:To evaluate the risk factors of systemic inflammatory response syndrome (SIRS) in the patients with type 2 diabetes diagnosed with kidney stone after percutaneous nephrolithotomy (PCNL).Methods:In this study,461 patients with type 2 diabetes who received PCNL in Peking Uni-versity People’s Hospital from June 2006 to December 2015 were reviewed.There were 281 males and 180 females with an average age of 57 years were included,of whom,137 were diagnosed with SIRS after PCNL.The demographic data,clinical features,and test results were compared between the patients with SIRS and without SIRS,trying to identify the correlation between their clinical characters and the occur-rence of SIRS.Results:The SIRS was significantly correlated with the patients’preoperative white blood cell counting (×109 /L)[7.76 (4.00 -17.96)vs.6.31 (2.00 -17.40),P <0.001 ],preopera-tional blood glucose level (mmol /L)[7.30 (3.08 -19.90)vs.6.40 (3.42 -16.78),P <0.001], operative time (min)[75 (20 -270)vs.60 (20 -200),P <0.001 ],length of stay (d)[12 (2 -46)vs.11 (3 -29),P =0.019],staghorn stones [38.8% (33 /85)vs.27.7% (104 /376),P =0.042],and preoperational urinary tract infection [36.8% (50 /136)vs.26.6% (81 /304),P =0.032].There was no significant correlation between the SIRS and the patients’age,body mass index, preoperative hemoglobin level,preoperative serum creatinine,and transfusion.In multivariate analysis, abnormal preoperative white blood cell counting (OR =3.194,95% CI:1.531 -6.666,P =0.002), operative time longer than 60 min (OR =1.635,95% CI:1.088 -2.456,P =0.018),and preopera-tional blood glucose level higher than normal 7.1 mmol /L were significantly correlated with the presence of SIRS.Conclusion:The high level of preoperational blood glucose,abnormal preoperative white blood cell counting,and long operative time were significantly correlated with the presence of SIRS in patients with type 2 diabetes after PCNL.

Objective To determine the coagulation status as well as circulating levels of complement and inflammation markers in patients with chronic urticaria (CU) during acute attack and in remission,and to estimate the relationship of coagulant and anticoagulant factors as well as fibrinolytic markers with the development of chronic urticaira.Methods This study included 40 patients with CU (22 during acute attack and 18 in remission) and 40 healthy blood donors from the Guangzhou Blood Center.Venous blood samples were obtained from these subjects,and enzyme-linked immunosorbent assay (ELISA) was performed to measure the plasma levels of prothrombin fragrnent 1 +2 (F1 +2),tissue factor (TF),thrombomodulin (TM),high molecular weight kininogen (HMWK),tissue-type plasminogen activator (t-PA),C5a and serum levels of C3,C4,antistreptolysin O antibodies (ASO),rheumatoid factor (RF) and C-reactive protein (CRP).Erythrocyte sedimentation rate (ESR) was also determined in these patients.Comparisons of these parameters were carried out by using t test,and the correlation of these factors with CU was evaluated by using Spearman correlation coefficient.Results Compared with the healthy controls,the patients with CU showed significantly higher plasma levels of F1+2 and HMWK (both P ＜ 0.01),but lower levels of TF,TM and t-PA (all P ＜ 0.01).The plasma levels of F1 +2,HMWK,t-PA were significantly correlated with the symptom scores in patients with CU (r =0.81,P ＜ 0.01; r =-0.39,P ＜ 0.05; r =0.35,P ＜ 0.05).A significant increase was observed in the plasma concentration of F1 +2 in patients during acute attack compared with those in remission (P ＜ 0.01),whereas no significant differences were noted in the plasma levels of TF,TM,HMWK,t-PA,C5a,serum levels of C3,C4,ASO,RF and CRP or ESR between the two groups of patients (all P ＞ 0.05).Conclusions It seems that coagulation,anti-coagulation and fibrinolysis are all involved in the development of urticaria.There is an obvious difference in the plasma level of prothrombin F1 +2 between patients with CU during acute attack and in remission,suggesting that coagulation factors play a certain role in the initiation and progression of CU.

Objective To investigate the feasibility and safety of laparoscopic aortobifemoral bypass (LABF) for diffuse aortoiliac occlusive diseases.Methods Clinical data of 18 cases who underwent LABF were retrospectively analyzed.The intraoperative procedures and postoperative outcome were evaluated.Results LABF was performed successfully in 17 of 18 patients.The mean operation time was (280 ±57) minutes,with a mean aortic cross-clamp time of (117 ±32) minutes.Estimated blood loss was(524 ±45) ml.Mean ICU stay was ( 1.0 ± 1.2) days.The mean postoperative hospital stay was ( 10 ±5) days.Mean time to resume diet was (3 ± 3 ) days.Postoperative myocardial infarction developed in 1 case,lung infection in 2 cases.There was no perioperative mortality.Graft thrombosis developed in 1 case and embolectomy surgery was successfully performed.All patients were followed up from 3 to 27 months,with mean follow-up of (18 ± 8) months,grafts were all patent.Conclusions Laparoscopic aortic bypass is feasible and miniinvasive in patients with diffuse aortoiliac occlusive disease.Short-term outcomes are comparable to those with open conventional aortic bypass.
