Objective To study the changes and clinical significance of serum kalium,natrium,chlorine,calcium and glucose in children with febrile convulsion(FC).Methods Serum kalium,natrium,chlorine,calcium and glucose concentrations were measured in 41 children with FC(FC group),30 children with fever and without convulsion(fever group) and 30 normal children(normal group) by automatic biochemical detector.Results Serum kalium and calcium concentrations had no significant difference between FC group and fever group,but they were significantly lower than those of normal group(F=5.965,3.048 P0.05).Conclusions There are hyponatremia,hyperglycemia and lowered blood kalium and calcium in patients with FC.Hence,while treating the patient with FC,the disturbance of blood electrolytes and glucose need be corrected to avoid the recurrence of FC and the progressive injury of important organs such as brain.

Objective To investigate the effects of recombinant human fibronectin fragment (RetroNectin) combined with anti-CD3 monoclonal antibody (CD3Ab) on the proliferation and cytotoxicity of cytokine-induced killer cells (CIK) from acute leukemia (AL). Methods Mononuclear cells (MNCs) were isolated from peripheral blood of complete remission AL pa-tients. The MNCs were cultured in vitro by precoating with RetroNectin (RN group), CD3Ab (CD3Ab group), RetroNectin com-bined with CD3Ab (RN+CD3Ab group) and traditional method (control group) to generate CIK. The changes of growth rate, characterization, cytotoxicity and apoptosis of CIK were determined between groups. Results The amplification of CIK was higher in experimental group than that of control group, and the amplification of CIK was higher in group RN+CD3Ab than that of in group RN and group CD3Ab (P＜0.05). The expression of CD25 positive cells was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P＜0.05).The percentage of G1 stage cells was lower in group RN and group RN+CD3Ab than that of group CD3Ab and control group. The percentage of S stage cells was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P＜0.05). The cytotoxicity was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P＜0.05) at the E/T scope 40∶1.The percentage of apoptotic cells was lower in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P ＜ 0.05). Conclusion These in vitro studies suggest that a higher activity of immune cells could be obtained by CIK cells cultured by precoating Ret-roNectin and CD3Ab.

Objective To investigate the expression of T cell immunoreceptor with Ig and immunoreceptor tyrosine-based inhibitory domains (TIGIT) on peripheral CD4+ T and CD8+ T cells from patients with rheumatoid arthritis (RA) and its significance in order to clarify its role in the development of RA.Methods Peripheral blood samples were collected from 81 patients with RA and 33 healthy controls (HC).Expression of TIGIT on the surface of peripheral blood leukocytes was detected by flow cytometry.Differences in TIGIT expression between RA and HC groups were comparatively analyzed.Correlations of TIGIT expression on CD4+ T and CD8+ T cells with several laboratory indexes were analyzed.All data were statistically analyzed.Results (1) The percentage of TIGIT-expressing CD3+ T cells in patients with RA was significantly higher than that in HC (P<0.01).Moreover, the median fluorescence intensity (MFI) of TIGIT on CD3+ T cells was significantly elevated in patients with RA as compared with that in HC (P<0.01).No significant difference in the expression of TIGIT on B cells, monocytes or neutrophils was observed between RA and HC groups.(2) The percentages of TIGIT-expressing CD4+ T and CD8+ T cells were significantly elevated in patients with RA as compared with those in HC (P<0.01).Moreover, the MFI of TIGIT on CD4+ T and CD8+ T cells were significantly elevated in patients with RA as compared with those in HC (P<0.01).(3) The percentages of both TIGIT-expressing CD4+ T cells and TIGIT-expressing CD8+ T cells in patients with RA were positively correlated with erythrocyte sedimentation rate (ESR) (rs=0.355, P<0.01;rs=0.277, P=0.013).(4) The percentages of both TIGIT-expressing CD4+ T cells and TIGIT-expressing CD8+ T cells in patients with RA were positively correlated with rheumatoid factor (RF) (rs=0.265, P=0.017;rs=0.366, P<0.01).The MFI of TIGIT on CD4+ T cells was positively correlated with RF in RA group (rs=0.226, P=0.043).The percentage of TIGIT-expressing CD4+ T cells was positively correlated with anti-cyclic citrullinated peptide (anti-CCP) antibody in patients with RA who were positive for anti-CCP antibody (rs=0.324, P=0.012).(5) The percentage of TIGIT-expressing CD4+ T cells as well as the MFI of TIGIT on CD4+ T cells in patients with RA was positively correlated with Disease Activity Score-28 (DAS28) (r=0.232, P=0.038;r=0.343, P<0.010).Conclusion The expression of TIGIT on T cells is elevated in patients with RA and correlated with inflammatory markers, antibody production and disease activity.

OBJECTIVE: To investigate the therapeutic effect of Yihuo Qingxia method, a traditional Chinese medicine therapeutic method for replenishing qi to activate blood, clearing away heat and dredging intestines, in treating hyperlipoidemia-related severe acute pancreatitis (SAP) in early stage. METHODS: One hundred and four patients with hyperlipoidemia-related SAP were divided into two groups: early group (admitted to hospital within 3 days after onset) and late group (admitted to hospital from 3 days to 7 days after onset). There were 52 cases in each group. All the patients were treated by Yihuo Qingxia method. RESULTS: There were no statistical differences in 48-hour Ranson scores, CT scores, 24-hour acute physiology and chronic heath evaluation II scores (APACHE II scores), and the levels of 24-hour serum triglyceride (TG) and serum glucose in the two groups (P>0.05). At the 10th day after onset, the serum TG level in early group was lower than that in late group (P<0.01). The incidences of acute respiratory distress syndrome, acute renal failure, hepatic inadequacy, congestive heart failure, shock, encephalopathy, infection and alimentary tract hemorrhage in early group were higher than those in late group (P<0.05). The mortality in early group was lower than that in the late group (P<0.05). The length of hospital stay in early group was shorter than that in late group (P<0.05). CONCLUSION: Yihuo Qingxia method has a good efficacy in treating hyperlipoidemia-related SAP in early stage.

To investigate the prognostic effects of integrated traditional Chinese and Western medicine therapy without antibiotics in treatment of patients with severe acute pancreatitis (SAP).

Objective To observe the effect of acupuncture on cystathionine gamma-lyase(CSE)and myeloperoxidase (MPO) in the colonic tissues of rats and to explore its mechanism for recovering the function of interstitial cells of Cajal(ICCs)in rats after colonic anastomosis . Methods Thirty SD rats were randomized into normal control group, model group(receiving colonic anastomosis) and acupuncture group. The acupuncture group received foot three-needle therapy on bilateral Zusanli(ST36), Sanyinjiao(SP6) and Taichong(LR3), once a day for 3 days after colonic anastomosis. And then the propulsive rate of the small intestine was measured. The count of ICCs with positively expressive c-kit in rat colonic tissues was measured by immunohistochemistry, the activity of CSE was observed by enzyme-linked immunosorbent assay (ELISA) and the activity of MPO was tested by biochemical method. Results Compared with the normal control group, the small intestinal propulsive rate in the model group was decreased, the number of ICCs with positively expressive c-kit was reduced, while the activities of CSE and MPO were increased(P<0.05). The acupuncture group had higher intestinal propulsive rate, more ICCs with positively expressive c-kit, and lower CSE and MPO activities than the model group(P<0.05).Conclusion Acupuncture can promote the recovering of postoperative gastrointestinal function, and its mechanism may be related to the regulation of CSE and MPO activities in the colonic tissues and to the restoration of ICCs function in the focus with positive c-kit.

Objective To evaluate the clinical significance of fetal nasal bone absence and thickened nuchal translucency ( NT) at 11-13 +6 weeks ultrasound screening .Methods A total of 4200 pregnant women with single fetus registered at Mother and Children ’ s Health Care Center in our hospital were examined at 11-13 +6 gestational weeks .Both fetal nasal bone and NT ultrasound evaluation were offered to assess whether nasal bone is absent and NT is thickened (>3.0 mm) in these cases.Particular attention was paid to the relationship between abnormal findings ,karyotype and pregnancy outcome .Results In all, 3492/4200 cases were included in the study with both NT measurement and nasal bone evaluation .Seven hundred and night cases were excluded because of unavailable clinical outcome .Among 3492 fetuses:(1) There were 3 cases absent of nasal bone .Among the 3 cases without nasal bone , 2 cases ( 1 case combined with thickened NT ) were trisomy 21(66.7%,2/3).(2) There were 351 cases with NT>3.0 mm (10.1%,351/3492).Among the 351 cases with thickened NT,there were 4 with trisomy 21 syndromes (1.14%,4/351,1 case combined with nasal bone absence ),1 with trisomy 18 syndrome,1 with Turner syndrome,6 with structural anomalies but normal karyotype (1.71%,6/351).(3)Among the 3139 cases with normal nasal bone and NT ,there were 8 cases with chromosomal or structural anomalies .Conclusions Absent nasal bone and thickened NT are important markers of trisomy 21 in the first trimester ultrasound screening .Thickened NT has significant correlation with other fetal chromosomal and structural anomalies .

OBJECTIVE: To investigate the mechanism of Chaiqin Chengqi Decoction (CQCQD), a compound of traditional Chinese herbal medicine, acting on the pancreatic acinar cell calcium overload in rats with acute pancreatitis (AP). METHODS: A total of 30 SD rats were randomly divided into normal control group, untreated group and CQCQD group (n=10, respectively). AP was induced in rats by caerulein (5x50 mug/kg) intraperitoneal injection within 4 h. The pancreatic tissue SERCA1 and SERCA2 mRNA expressions were detected by fluorescent quantization polymerase chain reaction method; intracellular calcium fluorescence intensity (FI) of pancreatic acinar cells and the pancreatic pathological score were measured by laser scanning confocal microscopy and light microscopy respectively. RESULTS: There were no SERCA1 mRNA expressions in pancreatic acinar cells of rats in the normal control group and the untreated group. The expression of pancreatic SERCA2 mRNA in the untreated group was down-regulated compared with that in the normal control group (expression ratio=0.536; P=0.001); the expression of pancreatic SERCA2 mRNA in the CQCQD group was up-regulated compared with that in the untreated group (expression ratio=2.00; P=0.012). The pancreatic pathological score in the CQCQD group was lower than that in the untreated group and the FI of Ca(2+) was also lower. CONCLUSION: CQCQD can up-regulate the expression of pancreatic SERCA2 mRNA, release the calcium overload, and hence reduce the pathological changes in pancreatic tissue.

OBJECTIVETo investigate the epidemiology and antibiotic resistance of isolates from hospitalized patients with hematological disease from 2005 to 2011.

METHODSA total of 1453 bacterial strains were isolated from patients with hematological disease from January 2005 to December 2011. Antimicrobial susceptibility testing was performed by micro-dilution method.

RESULTS(1) The majority of the bacterial strains were respiratory passage examples (57.5%). The portage of blood examples in our division (13.60%) was higher than of whole hospital (6.26%), with lower positive rate of bacterial culture (52.37%) than of whole hospital (60.24%). Chemotherapy-induced agranulocytosis was the main reason for hospital infection. 578 (39.8%) bacterial strains were gram positive, and 875 (60.2%) gram negative bacillus. Staphylococcus epidermidis strains and glucose nonfermenters had a tendency of ascensus. (2) Methicillin resistant staphylococcus aureus (MRSA) accounted for 72.8% antibiotic resistance. Detection rates of ESBLs in Escherichia coli and Klebsiella pneumoniae were 18.9% and 10.4%, respectively. (3) No obvious changes of antimicrobial resistances of Staphylococcus and Enterococcus were observed during these years. The Enterobacteriaceae strains showed lowest resistance rates to Carbapenems, next to Cefoperazone/sulbactam and Piperacillin/tazobactam. But the resistance rates of Escherichia coli to Cefepime and Ceftazidime were gradually increasing during the past years. Pseudomonas aeruginosa and Acinetobacter baumannii of glucose nonfermenters showed lowest resistance rates to Cefoperazone/sulbactam, but the resistance rate of Pseudomonas aeruginosa to Carbapenems increased.

CONCLUSIONSEscherichia coli was the highest in quantity of gram negative bacillus and glucose nonfermenters had a tendency of ascensus. The resistance rates of Escherichia coli to Cefepime and Ceftazidime, Pseudomonas aeruginosa to Carbapenems were gradually increasing in the past years.
