Objective To investigate the relationship between anti-lymphocyte antibody (ALA) and clinical and immunological parameters in primary Sj(o)gren syndrome (pSS).The significance of ALA and lymphopenia in pSS was explored.Methods Serum samples were obtained from 143 patients with pSS.Clinical and laboratory data were collected.Sera from 45 healthy individuals were collected as the controls.Serum ALA IgG was detected by indirect immunofluorescence test (IIFT).x2 test and t test were used for statistical analysis.The reasons of lymphopenia in pSS patients were analyzed.The correlation between ALA,lymphopenia and clinical manifestations as well as laboratory parameters was analyzed.Results ① Of the 143 pSS patients,25.2％(36/143) were serological positive for ALA,which was significantly higher than the normal group (6.5％,5/77) (x2=27.496,P＜O.01).② The prevalence of leukopenia (55.6％,20/36),lymphopenia (77.8％,28/36),anti-nuclear antibody(80.5％,29/36) and C3 decrease(50.0％,18/36) was higher in pSS patients with ALA than those without (x2=8.296,25.348,3.929,3.866,P＜0.05).③ 46.2％(66/143) patients had lymphopenia.Comparing with patients with normal lymphocyte count,the incidence of ALA positive,leukopenia,PLT decrease and anti-SSB antibodies positivity was significantly higher in patients with lymphopenia (x2=27.496,51.344,5.320,8.950,7.782; P＜0.05).Conclusion The ALA is likely to be a meaningful sera marker for pSS patients with lymphopenia,and this suggests that it has an important role in the clinical progress of SS.

Objective To investigate the clinical and laboratory features of autoimmune disease (AID) associated cryoglobulinaemia. Methods From April 2010 to May 2014, thirty threc patients with AID in Peking University Peopleˊs Hospital were tested positive for cryoglobulin. Their clinical and laboratory features were analyzed retrospectively. T test, Mann-Whitney U test, Chi-squaretest and Fisherˊs exact test were used for statistical analysis. Results Among the 33 patients, 26 were female, 7 were male, the average age was (47 ± 17) years old (range 12-75 years old). The spectrum of autoimmune diseases included, in order, systemic lupus erythematosus (SLE), Sj?grenˊs syndrome (SS), multiple myositis/dermatomyositis, rheumatoid arthritis (RA), systemic sclerosis (SSc), anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis, antiphospholipid syndrome and primary biliary cirrhosis. SLE and SS accounted for 84.8% (28/33) in tpatients with cryoglobulinaemia. In patients withSLE, cryoglobulinaemia occurred at 2.0 (1.0-12.0) years after disease onset, and cryoglobulinpositive patients had more frequent renal involvement (71% vs 40%, P=0.004), positive anti-RNP (56% vs21%, P=0.007) and ACL (53% vs 8%, P=0.000). However, among patients with SS, cryoglo-bulinaemia occurred at 11.0 (4.0-18.0) years after disease onset, and cryoglobulin positive patients had higher rheumatoid factors (RF) [1 170 (230.00, 2 800.00) U/ml vs 57.80 (20.00, 230.50) U/ml, U=-0.002, P=0.001], IgM [3.54 (1.83, 4.34) g/L vs 1.17 (0.81, 2.26) g/L , U=0.016, P=0.014] and lower complement C3 [0.58 (0.33, 0.68) g/L vs 0.81 (0.67, 0.98 g/L), U=0.004, P=0.003] and C4 [0.06 (0.03, 0.12) g/L vs 0.16 (0.12, 0.22), U=0.017, P=0.016]. Conclusion Autoimmune disease complicated with cryoglo-bulinaemia is not uncommon in clinical practice, in which SLE and SS account for the leading two causes. Patients with positive anti-RNP and/or ACL are positively associated with cryoglobulinaemia. renal involvement of SLE is increased by the presence of cryoglobulin.

Objective To study the disease spectrum,clinical and lab characteristic of cryoglobulinaemia.Methods The clinical and laboratory data of 58 patients with positive cryoglobulin admitted in Peking University People's Hospital from April 2010 to May 2014 were retrospectively analyzed.Results Among 58 patients,34 were diagnosed as autoimmune disease,8 as infectious disease,4 as hematological disease and 12 as primary cryoglobulinemia.Renal involvement was the most frequent clinical presentation among all cryoglobulin positive patients.Patients with autoimmune disease presented all clinical manifestations related to cryoglobulinaemia.Renal involvement (7/8) was prominent in patients with HBV/HCV infection,while other clinical presentations were rare.Among 4 patients with hematological disease,purpura was presented in 3 cases,renal involvement in 2,arthralgia in 2,fatigue,thrombosis or hyperviscosity was presented in 1 case,respectively;however,none of these patients had elevated rheumatoid factor (RF) level.Renal lesions were the most common reason for patients with primary cryoglobulinaemia to consult doctors,and 5 of them had positive antinuclear antibodies (ANA).Conclusions There is a broad spectrum of disease in cryoglobulinaemia.Multi-system involvement was most common in patients with autoimmune disease.For patients with HBV/HCV infection,extra-hepatic presentations were rare except renal involvement.Hyperviscosity syndrome tended to occur in patients with hematological disease.Since patients with primary cryoglobulinaemia had a relatively high rate of positive antinuclear antibodies,we should keep vigilance at the occurrence of autoimmune disease.

HPLC fingerprint of Congrong Zonggan capsule was established in order to provide basis for quality evaluation. With acteoside as the reference, HPLC was adopted for fingerprint analysis on Congrong Zonggan capsule. The chromatographic conditions wereas follows. Waters C18 column (4.6 mm x 150 mm, 5 μm) was used, with methylalcohol-0.1% formic acid as the mobile phase for gradient elution at the flow rate of 1.0 mL x min(-1). The detection wavelength was 330 nm, and the column temperature was 30 °C. This method was highly accurate and reproducible. All of the 13 components in tested samples reached the baseline resolved peak, and 15 batches of finished products showed the similarity of above 0.95. The method was accurate and feasible and could be used as a simple and effective method to evaluate the quality of the traditional Chinese medicines.

Aim To study the expression of caspase-12 mRNA and protein following focal cerebral ischemia-reperfusion in rats,and explore the effect of endoplasmic reticulum pathway on neuronal apoptosis.Methods 60 male Wistar rats were randomly divided into sham-operated group and ischemic group.The middle cerebral artery occlusion(MCAO)models were established by using the intraluminal suture occlusion method,neuronal apoptosis was detected by TUNEL staining,the expression of caspase-12 protein was detected by immunohistochemical staining,the expression of caspase-12 mRNA was detected by RT-PCR method.Results In ischemic group,the number of apoptotic cells and the expression of caspase-12 mRNA and protein were gradually increased following prolonged cerebral reperfusion,reached the peak at 24 h.The number of apoptotic cells and the expression of caspase-12 mRNA and protein in ischemic group were significantly less than those of sham-operated group at all times(P

OBJECTIVETo discuss the management of extracorporeal circulation (ECC) for robotically assisted cardiac surgery.

METHODSA total of 71 patients underwent cardiac surgeries using da Vinci S robotic surgical system, including 49 undergoing atrial septal defect repair (ASDR), 13 undergoing mitral valvuloplasty (MVP), 8 receiving left atrial myxoma excision and 1 having right atrial myxoma excision. For most of the patients, ECC was established through the femoral arterial cannula, femoral venous cannula and right internal jugular venous cannula, with only 1 patient undergoing MVP with femorai arterial cannula and femoral venous cannula. In all the cases, vacuum-assisted venous drainage (VAVD), continuous blood gas monitoring and ultrafiltration were used during ECC. Myocardial protection was managed with 4:1 blood cardioplegic solution (61 cases) or HTK solution (10 cases receiving MVP).

RESULTSThe mean ECC time and aortic cross-clamp time was 116.1-/+35.5 min (range 45-206 min) and 58.5-/+23.6 min (range 27-132 min) in these patients, respectively. During ECC, the mean urine volume was 825.5-/+447.3 ml (200-1900 ml) and ultrafiltration volume was 2571.1-/+885.9 ml (800-4800 ml) with subzero-balanced (58 cases) or zero-balanced (9 cases) total fluid balance. The mean postoperative intubation time was 10.1-/+5.3 h (7-17 h) and drainage volume within 24 h postoperatively was 217.5-/+167.8 ml (80-680 ml).

CONCLUSIONThe establishment of ECC system through peripheral vessels, certain learning curve of perfusion technique and close communication between the surgical team are the key points of ECC for totally robotically assisted cardiac surgery, and VAVD and continuous blood gas monitoring are essential during ECC.
