Chinese Journal of Postgraduates of Medicine 2012;35(10):15-17
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 explore the determination of urinary angiotensinogen (uAGT) in the urine of children with obstructive hydronephrosis and its relationship with impaired renal function, to provide a new and rapid reference index for the preoperative evaluation and postoperative follow-up of the children with hydronephrosis.Methods The data were collected from 48 children who were diagnosed as unilateral congenital renal pelvis and ureter obstruction in the outpatient or inpatient Department of Pediatric Surgery of the First Affiliated Hospital of Zhengzhou University,which were divided into operation group and non-operation group.There were 28 children in operation group(who were all severe hydronephrosis) ,who were all operated with dismembered pyeloplasty.There were 20 children in the non-operation group (who were all mild and moderate hydronephrosis).They temporarily had no surgery signs and hydronephrosis did not become increasingly serious for assuring the regular outpatient follow-up after being diagnosed as hydronephrosis;there were 20 children in the control group, 10 of which were male, and 10 female.The males were hospitalized children with hydrocele and the females were with inguinal hernia.Gender composition among the 3 groups, and the average age difference was not statistically significant.The clean urina of children in 3 groups was collected,3 times for operation group, once before operation and once in 6 weeks and once in 12 weeks after operation;3 times for non-operation group and control group with interval of 6 weeks in outpatient clinic.The children in operation group and non-operation group were all scanned for glomerular filtration rate (GFR) of diseased renal with radionuclide;enzyme-linked immunosorbent assay (ELISA) was adopted to determine the content of uAGT in the urine of the 3 groups of children, and automatic biochemical analyzer was used to measure the amount of urine creatinine (uCr).Results Before operation, in 6 weeks and 12 weeks after operation, uAGT / uCr average water of non-operation group and control group was significantly lower than the operation group, all the differences were statistically significant (F =34.360,14.683,5.035, all P < 0.05).Preoperative and postoperative uAGT / uCr and GFR of diseased renal were of negative correlation(r =-0.647,-0.786, all P < 0.05).In operation group, the preoperative and postoperative GFR average of diseased renal was 37.18 ± 7.31 and 45.27 ± 8.18.The difference of GFR changes was statistically significant before and after treatment (t =-3.971, P =0.000).Conclusions uAGT/uCr increased evidently in congenital renal pelvis and ureter obstruction patients who needed operation, so increase of uAGT might be the indicator of impaired renal function caused by obstructive hydronephrosis of children.
