1.Research progress of Bruton tyrosine kinase in B cell malignances
Journal of Leukemia & Lymphoma 2014;23(6):378-380
Bruton tyrosine kinase (Btk) is a member of the non-receptor protein tyrosine kinases of Tec family.It plays an important role in growth,proliferation,differentiation and signal transduction of B lymphocyte.After activation of B-cell receptor (BCR) by diverse stimuli,Btk is activated through tyrosine phosphorylation.Activated Btk can stimulate several downstream signaling proteins.Btk and BCR signaling pathways play important roles in initiation and maintenance of B cell malignancies.This review focuses on the recent findings in association of Btk and B cell malignancies.

Objective To investigate the immune disorder in elderly patients with severe ischemic stroke and to explore whether a new type of diabetes-specific enteral nutrition formula can regulate the immune function of these patients.Methods In the randomized controlled prospective study,90 patients aged 60-80 years with acute ischemic stroke and NIHSS score more than 10 and dysphagia were randomized to two groups:receiving a new type(Group A) of,versus traditional(Group B) diabetes-specific enteral nutrition.30 Patients aged 60-80 years with acute ischemic stroke and NIHSS score ≥10 without dysphagia were enrolled as control(Group C).The immune function was observed,and the nutritional status and immunological function were compared between two different enteral nutrition groups at 7 days of treatment.Results After 7 day follow-up,the serum lipid stats significantly ameliorated in group A.An obvious suppression of immune state was observed in severe acute ischemic patients at onset of 7 days.At day 7 of treatment,the percentage of CD3+ T cells in group A was(69.25±9.93)% after treatment vs.(63.36±7.79)% at baseline(P<0.001),and CD3 +CD4+T cells was(45.79±9.47)% after treatment vs.(36.12±9.15)% at baseline(P<0.001),as well as CD4+/CD8+ cells were(2.27±1.40)% after treatment vs.(1.70±0.82)% at baseline(P=0.001).At 7 days of treatment,the percentage of CD3+ T cells was higher in group A (69.25 ±9.93) % than in group B(63.07± 9.47) % (P<0.001),and the percentage of CD3 + CD4 cells was higher in group A(45.79 ± 9.47) % than in group B(41.32 ± 8.89) % (P=0.024).Conclusions Enteral nutrition preparations can provide sufficient energy support in the acute ischemic stroke.Immunosuppressive state exists in patients with acute phase of severe ischemic stroke.The new type of diabetic enteral nutrition formula can significantly improve immunosuppressive state in patients with acute severe stroke.

Objective To assess the public health service quality objectively in Shenzhen,and promote the equity of basic public health services.Methods The criterion and method of the assessment were established by municipal health administrative department,the assessment of institutions and regions were conducted by experts selected by municipal professional institutions.Regional assessment was the comprehensive evaluation of public health service qualities of professional public health institutions,medical institutions and the community health centers.The assessment of the degree of public health service quality satisfaction was accomplished by a third-party institution.Results The accomplishment ratio of indicators for public health service quality was 93.2%.This ratio has witnessed a high increase with mental health institutions,occupational disease prevention and control institutions and health education institutions on one hand.On the other,it has dropped with institutions of disease control,chronic disease control and medical institutions within the region.On the whole,this ratio has increased with all the districts to different extents.Despite the overall improvement of public health capabilities citywide,imbalances are found among districts and institutions as well.Conclusion It is imperative to further improve the public health service system and equity while carrying out specific tasks in this respect.

Objective To study roles of GRP78 and GRP94 in tumorigenesis and progression of colorectal carcinomas (CRC).Methods Colorectal carcinoma tissues of 124 cases were studied for GRP78 and GRP94 proteins by immunohistochemistry and Western blotting.The correlations among the expression of proteins and clinicopathologic parameters and overall survival of CRC were analyzed using univariate and Cox regression analyses.Results The overexpression of GRP78 and GRP94 was detected in the cytoplasms or plasma membrane of the tumor cells.They were positively correlated with tumor differentiation,staging,lymph node metastasis and remote metastasis.Survival analysis showed that overexpression of both proteins was associated with poor outcome of CRC ( P =0.025,P =0.010,respectively).Cox regression analysis demonstrated that the expression of GRP94 was an independent poor prognostic factor for CRC.Conclusions Up-regulated expression of GRP78 and GRP94 was possibly involved in the pathogenesis,growth,invasion and metastasis of colorectal carcinomas.GRP78 and GRP94could be seen as a marker for the aggressive behavior and poor prognosis in colorectal carcinomas.

Objective To investigate the accuracy of predicting middle cerebral artery infaction with contin -ue electroencephalograph .Methods 40 cases with middle cerebral artery infaction were divided into malignant groups(14) and binigan groups(26).They were all with continued beside electroencephalograph within 24 hours after admission.Results Abnormal CEEG rate in malignant groups [85.71%(12/14)]was significantly higher than that in binigan groups[65.38%(17/26)](χ2 =10.405,P=0.001).In malignant groups,severe abnormal CEEG was seen in 4 cases developed coma at the second day of admission ,moderate abnormal CEEG was found in 6 cases,slight abnormal CEEG was detected in 2 cases,normal CEEG was detected in 2 cases.Conclusion Early CEEG has a cer-tain value for predicting middle cerebral artery infaction .

Objective To investigate the protective effects of ambroxol on lung during perioperation in elderly patients with myasthenia gravis.Methods 58 elderly patients diagnosed as myasthenia gravis combined with thymic disease were divided into treatment group and control group randomly.During the perioperation,the treatment group was treated with ambroxol,while the control group was not.Comparative analysis of pulmonary complications,pulmonary ventilation indexes,blood gas indexes,and serum concentration of C-reactive protein (CRP),tumor necrosis factor-α (TNF-α),interleukin 1β (IL-1β) and IL-10 was performed.Results The incidence rate of postoperative pulmonary complications (pulmonary atelectasis,pneumonia and bronchitis) was significantly lower in the treatment group in the control group (9.4% vs 15.6%,P<0.05).Peak inspiratory pressure (PIP) and resistance of air way (RAW) were lower in treatment group than in control group [(22.32±3.43) cmH2O vs (26.54±4.81) cmH2O,(29.17±5.74) cmH2O· L-1s-1vs (34.47±7.94) cmH2O · L-1 · s-1 both P<0.05],while compliance of lung (CL) washigher in treatment group than in control group [(106.04±-14.73)ml/cmH2O vs (95.11±9.50) ml/cmH2O,P<0.05].Two days after operation,PaO2,SaO2 and PaO2/FiO2 were significantly higher in treatment group than in control group [(89.66 ±13.23) mmHg vs (70.94±12.75) mmHg,(96.95±2.65)% vs (89.44±2.78)%,(219.47±54.05)mmHg vs (187.38±37.72) mmHg,respectively,all P<0.05].Serum concentration of CRP,TNF-α,IL-1β were lower and serum level of IL-10 was higher in treatment group than in control group [(29.37 ± 14.87)mg/L vs (43.94 ±21.42) mg/L,(35.55±4.74)μg/L vs.(52.80±6.63) μg/L,(17.06±6.85)μg/L vs.(28.62±7.72) μg/L],[(132.84± 12.91)μg/L vs.(87.18± 16.37)μg/L,respectively,all P<0.05].Conclusions Ambroxol hydrochloride can effectively reduce the incidence rate of postoperative pulmonary complications after thymectomy,improve the pulmonary ventilation function,and inhibit the inflammatory reaction in elderly patients with myasthenia gravis,which is worthy of wide application in the perioperation.

Selection of utilization of carbon source in soya oligosaccharide by three strains of S.cerevisiae was studied.The results showed that S.cerevisiae C could selectively utilize sucrose and the residual rate of stachyose and raffinose could be more than 96%.Using yeast extract as nitrogen source,the sucrose could be used up after 36 hours of culture.Further study showed that the content of sucrose in soya oligosaccharide powder was less than 1.3% after fermentation of waste water of soy whey and downstream processing.
