Postural tachycardia syndrome (POTS)is one common type of orthostatic intolerance (OI)in chil-dren.POTS is characterized by OI symptoms and excessively increased heart rate from supine to upright position.Main treatments for POTS are physical training,automatic function exercise and medications including α-receptor agonists,β-receptor blockers and oral rehydration salts.This review aimed to summarize the biomarkers in the diagnosis and treatment of POTS.

Objective:Primary nodal and extranodal diffuse large B-cell lymphoma(DLBCL)were investigated for the heterogeneity of histopathology and immunophenotype,and their relation to clinical stage,comparatively.Whether E2F1 can be used as a germinal center B cell(GCB)DLBCL marker was also discussed.Methods:Classification of histopathology and immunophenotype of 98 cases were studied by immunohistochemistry in tissue microarray.Results:Histopathologic morphology presented as:centroblastic(CB,88.8%,87/98),immunoblastic(IB,5.1%,5/98),anaplastic(ALCL,3.1%,3/98),and T cell rich B cell lymphoma(TCRBCL,3.1%,3/98).Of which,31 cases were GCB DLBCL,10(20.8%,10/48)nodal,and 21 extranodal(42%,21/50,P=0.024).The rates of Stages Ⅰ/Ⅱ in nodal and extranodal area were 48.5% and 70%,respectively(P=0.015).The rate of Stage Ⅰ/Ⅱ in GCB DLBCL(74.2%)were higher than in non-GCB DLBCL(50.7%,P=0.029).The CD10 positive rates were 36.8% and 17.1% in Stages Ⅰ/Ⅱ and Ⅲ/Ⅳ,respectively,and had significant differences(P=0.033).The CD10 positive rates were 18.8% and 38% in nodal and extranodal area,respectively(P=0.035).The positive rates of E2F1 were 38.8% and 16.5% in GCB and non-GCB DLBCL,respectively,and had significant differences(P=0.016).The positive rate of E2F1 had positive relation with the expression of CD10 and Bcl-6(P

Objective:To assess the expression of specific virulence-associated Helicobacter pylori (Hp) genotypes, (cag A, vac A, and ice A status) in primary gastrointestinal B cell lymphoma. Methods: Forty-nine paraffin wax embedded tissues were analyzed by immunohistochemical staining and poly-merase chain reaction. Results:There were 14 cases of mucosa associated lymphoid tissue lymphoma ( MALT-L) (8 in stomach, and 6 in intestine) and 35 cases of diffuse large B cell lymphoma (DLBCL) (21 in stomach, and 14 in intestine) in all. The positive rates of vac A s1 ,vac A s2 ,vac A m2,ice A 1 and cag A were 50. 0% ,42. 9% ,50. 0% , 14. 3% and 85. 7% in MALT-L; 57. 1% ,40. 0% ,25. 7% , 5.7% and91.4% in DLBCL, respectively. Conclusion:High toxicity cag A + Hp strains.seem to play a role in the pathogenesis of gastrointestinal B cell lymphoma, whereas vac A m2 may be more associated with MALT-L. Clinical stage was not associated with virulence-associated Hp genotypes.

Objective: To study the effects of immature orange fruit(IOF) and dried tangerine peel(DTP) on the resting tension of isolated aortic muscle strips in rabbits and their mechanisms. Methods: The organ-bath was used to observe the response of aortic strip to IOF and DTP. Results: IOF and DTP dose-dependently increased the tension of aortic strip, and the action of IOF was more significant than that of the same concentration DTP. 10 -7 mol/L phentolamine, 10 -5 mol/L verapamil or incubation with Ca 2+ -free Krebs solution could block the effects of IOF and DTP partly, but 10 -6 mol/L diphenhydramine could not. In endothelium-removed aortic strips, the effects of IOF and DTP decreased after treatment with 10 -7 mol/L atropine. Conclusions: IOF and DTP can contract vascular smooth muscle, which probably contribute to ? adrenergic receptor, cholinergic M receptor on membrane of vascular smooth muscle partly, and is dependent Ca 2+ influx through verapamil-sensitive Ca 2+ channels, but is not related to H 1 histamine receptor.

METHODS:Under the conditions that ratio of salt and medicinal materials was 1:50,4-5 times salt of adding water,brine run time was 2 h,the amounts of psoralen and isopsoralen in salt frying samples after 10,12,14 min of frying under 150 ℃,170 ℃,190 ℃ and in salt steaming samples after 1,1.5,2,2.5 h of steaming were re-spectively investigated,and the effects of 2 processing technology were compared. RESULTS:Under fixed condition,the contents of index components was the highest in salt frying samples by fried for 12 min under 150 ℃ and in salt steaming samples by steamed for 1 h;the content in salt steaming samples (1.49%) was higher than that in salt frying samples (1.29%)(P=0.011). CONCLUSIONS:According to the comparison of index components'contents in processing samples,salt steaming is superior to salt frying of P. corylifolia.

AIM: To detect the protein expression of protein gene product (PGP9.5) in cervical carcinoma samples, and to explore its relationship with clinicopathological features and prognosis of cervical carcinoma patients.The potential value of PGP9.5-siRNA in the treatment of cervical cancer was preliminarily investigated in vitro.METHODS:The clinical data of cervical cancer patients ( n=180 ) who received surgical treatment in Department of Gynecology of Tianjin Fifth Central Hospital and Tianjin Central Hospital of Gynecology and Obstetrics from January 2008 to June 2015 were retrospectively analyzed.Immunohistochemical staining for PGP9.5 in all pathological specimens from cervical cancer biopsy was performed.The patients were divided into high expression of PGP9.5 group and low expression of PGP9.5 group.The relationship between PGP9.5 expression and clinicopathological parameters, such as age, HPV infection, path-ological grade, tumor diameter, lymph node metastasis, depth of invasion and clinical stage, were analyzed.The overall survival was analyzed by Kaplan-Meier method and the log-rank test.The PGP9.5-siRNA, NC-siRNA, PGP9.5 eukaryotic expression plasmid and empty vector were transfected into the SiHa cells, and the effects of PGP9.5 expression on the abili-
ties of colony formation and cell invasion were determined by Western blot, colony formation assay and Transwell experi-ment.RESULTS:The relationships between the expression level of PGP9.5 and patients’ pathological characteristics in-cluding grade, tumor size, lymph node metastasis, depth of invasion, vascular involvement and clinical stage were statisti-cally significant ( P<0.05) .The overall survival rates of 3 and 5 years in PGP9.5 high expression group were significantly lower than those in PGP9.5 low expression group ( P<0.05 ) .Compared with control group, the protein expression of PGP9.5, the number of colony formation and the number of invasive cells in si-PGP9.5 group were significantly decreased. The protein expression of PGP9.5, the number of colony formation and the number of invasive cells in PGP9.5 group were significantly increased.CONCLUSION:Over-expression of PGP9.5 protein indicates poor prognosis of cervical cancer, which may be a good predictor for the prognosis of cervical cancer patients.Inhibition of PGP9.5 expression may be an ef-fective way of gene therapy for cervical cancer.

ObjectiveTo explore the treatment efficacy and feasibility of large dose of cytidine diphosphate choline (CDPC) in cardiopulmonary cerebral resuscitation.MethodsOne hundred and thirtytwo patients with sudden cardiac arrest successfully treated by the cardiopulmonary cerebral resuscitation were divided into treatment group ( 75 patients) and control group (57 patients) by random number tables.Two groups of patients were given adrenaline resuscitation drugs,reducing the intracranial pressure drugs,hypothermia,hormones and other basic treatment.Control group used CDPC 0.25 g with glucoseinjection 300 ml to do intravenous drip (once a day,21 days as a period of treatment),and treatment group added CDPC to 2.00 g.The patients were treated by basic traditional analeptic.The Glasgow coma scale (GCS) was carried out in two groups in admission to hospital and 3,7,14,21 days after treatment,and the changes of lysophosphatidic acid (LPA) and phosphatidic acid (AP) level were monitored.ResultsThe GCS score was significantly higher in treatment group 7,14,21 days after treatment(P ＜ 0.05 or ＜ 0.01 ),but GCS score had no significant difference before and after treatment in control group(P ＞ 0.05).The level of LPA in treatment group was significantly decreased 14 days after treatment [ (2.98 ± 0.28) μmol/L ] and 21 days after treatment[ (1.85 ± 0.21)μmol/L],and had significant difference compared with that admission to hospital [ (3.75 ± 0.22) μ mol/L ] (P ＜ 0.05 or ＜ 0.01 ).In control group,there was no significant difference before and after treatment (P ＞0.05).The level of AP in treatment group 21 days after treatment was significantly decreased compared with that in control group [ ( 3.45 ± 0.23 ) μ mol/L vs.( 5.20 ± 0.21 ) μ mol/L ](P ＜ 0.01).ConclusionLarge dose of CDPC can improve neurological function of cardiopulmonary cerebral resuscitation,which is a safe,effective and easy way to be popularized.

Objective: To investigate primary gastrointestinal B cell non Hodgkin’s lymphoma for clinicopathological features, proliferation, apoptosis and its association with Helicobacter pylori (HP). Methods: Classification of tumors, expression of HP, proliferation and apoptosis related gene products were studied by immunohistochemistry. Apoptosis was studied by TUNEL (TdT [terminal deoxynucleotidyl transferase] dUTP nick end labeling). Results: There were 15 cases of mucosa associated lymphoid tissue (MALT) lymphoma (9 in stomach, 6 in intestine) and 42 cases of diffuse large B cell lymphoma (DLBCL) (28 in stomach, 14 in intestine) in all the 57 cases of primary gastrointestinal BCL. The average apoptotic indexes (AI) were 0.16%, 2.54% in MALT lymphoma and DLBCL respectively. The average proliferation indexes (PI) were 2.22% and 8.71%,respectively. The p53 positive rates were 6.7% and 35.7%. PI ( P =0.026) and p53 ( P =0.044) had significant differences; But Bcl 2 positive rates were 60.0% and 35.7%,and HP positive rates were 66.7% and 23.8%, respectively. HP had significant differences ( P =0.005). Conclusion: HP and gastrointestinal MALT lymphoma had significant relation. Apoptosis and proliferative activity were higher in DLBCL than in MALT. The higher Bcl 2 expression in MALT may be related to lower apoptosis. p53 promotes apoptosis and p53 gene mutation may play a role in the progression from MALT to DLBCL. HP antibody may be used in HP detection in gastrointestinal BCL.
