ObjectiveTo analyze the significance of serum hyper sensitivity C-reactive protein (hs-CRP),lipoprotein (a) [ Lp(a) ] and total cholesterol (TC)/high density lipoprotein cholesterol ( HDL-C )in coronary heart disease.Methods From September 2010 to September 2011,the levels of serum hs-CRP,Lp (a) and TC/HDL-C were detected in 176 patients of coronary heart disease (coronary heart disease group ) and 60 healthy controls (control group).Coronary heart disease group included acute myocardial infarction with 56 cases,stable angina with 58 cases and unstable angina with 62 cases.ResultsThe levels of serum hs-C RP,Lp ( a ) and TC/HDL-C in coronary h cart disease group were (34.51 ± 9.65 ) mg/L,(295.16 ±104.57) mg/L and 4.23 ±0.91,while those in control group were (1.26 ±0.69) mg/L,(145.26 ±42.19)mg/L and 2.54 ± 0.57.There were significant differences between two groups (P ＜ 0.05 ).The levels of serum hs-CRP,Lp(a) and TC/HDL-C in acute myocardial infarction patients were significantly higher than those in unstable angina patients and stable angina patients (P ＜ 0.05).The levels of serum hs-CRP,Lp (a) and TC/HDL-C in unstable angina patients were significantly higher than those in stable angina patients(P ＜ 0.05).Conclusions Serum hs-CRP,Lp (a) and TC/HDL-C are significantly increased in coronary heart disease,and can reflex the severity of coronary heart disease.

Objective To investigate the brain protection of adenosine preconditioning in infants with tetralngy of Fallot (TOF) undergoing open heart surgery. Methods 120 patients with TOF undergoing open heart surgery were randomly divided into two groups: adenosine group and control group. Total dosage of 1.5 mg/kg adenosine was intravenously dripped in the adenosine group before the cardiopulmonary bypass. Serum S-100β and neurone specific enolase (NSE) were measured before the cardipulminary bypass, 30 min and 12 hours after the aorta off clamping. Results At 30 min and 12 hour after opening the aorta, the S-100β[(0. 346±0. 162)μg/L vs. (0.717±0.260) μg/L and (0.541±0.272) μg/L vs. (1.140±0.567) μg/L,P <0.001 ]and NSE[(10.43±5.54) μg/L vs. (15.75±7.96)μg/Land (15.54±7. 98)μg/L vs. (23.67±8.00)μg/L,P<0.001]were both lower in adenosine group than that in control group. Conclusion Adenosine preconditioning can reduce the S-100β and NES in infants with TOF undergoing open heart surgery and has brain protection.

Objective To characterize the human cell mediated immune response to Treponema pallidum(TP), and to determine the effect of TP infection on the various lymphocyte subpopulations and natural killer cells in the peripheral blood of the patients. Methods Twenty four untreated patients with early syphilis were analyzed,including 3 groups of 8 patients with disseminated syphilides,palmoplantar syphilides and latent syphilis each. Monoclonal antibodies of CD labeled with either fluorescein isothiocyanate or phycoerythrin were used on a flow cytometry to detect the changing of peripheral blood lymphocyte immunophenotypes. Results The results showed that the percentages of panT,T H,NK cells and the ratio of T H/T S were significantly lower (P0.05). Conclusion It suggests that there is prominent suppression of cellular immunity in the untreated patients suffering from early syphilis. Meanwhile, the difference of 3 groups in skin lesions was due to the different dermatobarrier function against the systemic invasion of TP, rather than attributed to the alteration of the lymphocyte immunophenotypes in the peripheral blood.

Objective To study the clinical, histological and immunohistochemical features of breast hamartomas. Methods The specimens were fixed in 10% formalin and embedded in paraffin. The sections were stained with hematoxylin and eosin for histological diagnosis. SP technique was used in the immunohistochemical study.Results We have 8 cases of breast hamartomas with well defined borders microscopically, histologically composed of ducts, lobules, fibrous stroma, adipose tissue. None of the epithelial elements showed any evidence of atypia. Immunohistochemical analysis showed that there was a variable number of epithelial cells showing a nuclear staining for estrogen receptor(ER) in all cases.Conclution Mammary hamartomas are benign tumor like lesions, histologically dissimillar from other breast tumors. It is affected by hormonal factors. The diagnosis is achieved by combining clinical, radiological and pathologic results.

Objective To observe the clinical efficacy of umbilicus application withDa Huang (Rheum Officinale) during 5-7 a.m. in treating senile constipation after hip fracture.Method Fifty-nine elderly patients with constipation after hip fracture were randomized into a treatment group of 30 cases and a control group of 29 cases. The treatment group was intervened by umbilicus application withDa Huang (Rheum Officinale) during 5-7 a.m, while the control group was by umbilicus application withDa Huang (Rheum Officinale) at any time but avoiding 5-7 a.m. period. After a treatment course, the therapeutic efficacy was evaluated based on bowel movement frequency and shape of stool, and the two groups were compared with each other.Result The total effective rate and markedly-effective rate were respectively 93.3% and 70.0% in the treatment group versus 82.8% and 37.9% in the control group. The between-group difference in the total effective rate was statistically insignificant (P>0.05); there was a significant difference in comparing the markedly-effective rate between the two groups (P<0.01).Conclusion Umbilicus application withDa Huang (Rheum Officinale) during 5-7 a.m. is an effective method in treating senile constipation after hip fracture.

Objective To observe IL-2 and IL-6 changes in the breast tumor Bcap-37 cells reated by hematoporphyrin nonomethyl ether mediated photodynamic therapy (HMME-PDT).Methods Cells in logarithmic growth phase were collected among breast cancer cells cultured in conventional methods.According to blank control group or the experimental group (laser irradiation group,photosensitive agent group and HMME-PDT group),PDT in addition to HMME and HMME-PDT were conducted.The changes of IL-2,IL-6 were detected by radioimmunoassay.Results After HMME-PDT,IL-2 was increased as time passed.After 12,24 and 48 h,compared with IL-2 level in the control group,in laser irradiation group or photosensitive agent group,the levels of IL-2 in HMME-PDT group was significantly differences (P ＜ 0.05).But IL-6 levels decreased.The most obvious changes of IL-6 levels happened at 12h and 24h.There was significant differences between IL-6 in HMME-PDT group with the control group,laser irradiation group or photosensitive agent group (P ＜ 0.05).Conclusion HMME-PDT maybe have destruction effect by altering IL-2,IL-6 activity on breast tumor cells,which provides objective indicators for clinical patients to regulate immune function and auxiliary diagnosis.

Objective To observe whether hydrogen sulfide modulates adipocytes to secrete adiponectin.Methods Thirty-two male SD rats were randomly divided into normal diet group (n =8),high-fat diet group (n =8),high-fat + cysteine group (n =8),and high-fat + propargylglycine (cystathionine-γ-lyase inhibitor) group (n =8).The fatty liver animal model was established using the high fat diet; meanwhile,L-cysteine was applied to the animals to produce endogenous hydrogen sulfide and propargylglycine to inhibit the production of endogenous hydrogen sulfide.Fatty degeneration of the hver of animals and plasma within the adiponectin concentration was observed after 8 weeks.The omental adipose tissues were excluded and digested using collagenase Ⅰ to isolate fat cells.Sodium hydrosulfide and propargylglycine was applied to stimulate the cells in vitro for 7 days before the detection of the cell supernatant adiponectin content.Results Liver steatosis was established after highfat diet for eight weeks.Steatosis was significantly extenuated after the application of L-cysteine and aggravated by propargylglycine.Plasma hydrogen sulfide and adiponectin levels in fat diet group animals were (21.13 ± 7.06) mmol/L and (3.16 ± 1.15) mg/L respectively,which significantly decreased when compared with the normal diet group with the levels of hydrogen sulfide (29.13 ± 13.06) mmol/L and adiponectin (8.98 ± 2.84) mg/L (P=0.0229,P=0.0062).Hydrogen sulfide [(35.47 ±9.04) mmol/L] and adiponectin [(6.54 ± 1.38) mg/L] levels in the high fat + cysteine group significantly increased (P =0.0032,P =0.0131).However,hydrogen sulfide [(16.65 ±8.79) mmol/L] and adiponectin [(2.50±0.91) mg/L] in high fat + propargylglycine group were significantly decreased (P =0.0191,P =0.0021).Hydrogen sulfide was not significantly differem in the supematam of adipocyte isolated from normal diet group [(26.77 ± 12.65) mmol/L] and from high-fat diet group [(28.76 ±9.09) mmol/L] (P =0.0927),but that in the sodium hydrosulfide and propargylglycine ceils supematants significandy either increased or decreased (P =0.0000,P =0.0000).Adiponectin in the supematants of high-fat diet group and normal diet group adipocyte showed no significant difference [(4.21 ± 1.61) mg/L vs (4.49 ± 1.09) mg/L,P =0.1076)].The levels of adiponectin in sodium hydrosulfide and propargylglycine cell supernatants increased and decreased respectively than that in higher fat diet group cells [(5.77 ±0.86) mg/L vs (4.21 ±1.61) mg/L,P =0.0094; (3.01 ±1.26) mg/L vs (4.21 ± 1.61) mg/L,P =0.0108].Conclusion Hydrogen sulfide promotes adipocytes to secrete adiponectin.

Objective To explore the action mechanism and clinical significance of CD4+CD25+ regulatory T (Treg) cells in the development of atopic dermatitis (AD). Methods Peripheral blood mononuclear cells (PBMC) were obtained from 46 patients with AD and 20 normal human controls. Flow cytometry was performed to detect the number of CD4+CD25+ Treg cells, real-time fluorescence PCR assay to measure the Foxp3 mRNA level in PBMC, ELISA to determine the serum levels of IL-2, IL-4, IL-10 and IFN-γ. Results A statistical decrease was observed in the percentages of peripheral CD4+CD25+ Treg cells among CD3+ T cells and CD4+ T cells in AD patients compared with normal controls (t' = 3.775, 4.533, both P＜ 0.01 ), and in the percentage of peripheral CD4+CD25+ Treg cells among CD3+ T cells in patients with acute AD compared with those with chronic AD (t = 2.217, P ＜ 0.05), but no significant difference was noted between patients with acute AD and those with subacute AD or between those with subacute AD and those with chronic AD in the percentage of peripheral CD4+CD25+ Treg cells among CD3+ T cells (t = 1.558, 0.49, both P ＞ 0.05). The mRNA level of Foxp3 in PBMC from AD patients was statistically decreased compred with that from normal controls (z =-2.368, P ＜ 0.05 ). The count of CD4+CD25+ Treg cells was positively correlated with serum levels of IL-2 and IL-10 (r = 0.512, 0.494, both P ＜ 0.05), but had no significant correlation with serum levels of IL-4 and IFN-γ (r = -0.110, -0.237, both P ＞ 0.05). Conclusions In AD patients, there is a decrease in the count of CD4+CD25+ Treg cells and in the level of Foxp3 mRNA, which may suppress the proliferation of and secretion of Foxp3 mRNA by Th2 cells, lead to Th2 predominance, participate in the development of AD.
