Objective To explore clinical significence of soluble vascular cell adhesion molecular(SVCAM - 1),immunoglobulin A (IgA) anti- endothelial cells antibodies(AECA) in Henoch-Schonlein purpura(HSP) and their relationships. Methods SVCAM-1 were detected by ELISA between 55 cases with HSP (40 cases in acute stage and 15 cases in recovery) and 20 controls. Results The levels of serum SVCAM - 1 of the HSPN cases were significantly increased compared with the other HSP. In addition, the serum level of SVCAM - 1 in acute stage HSP children was significantly higher than that in recovery stage and normal controls. IgA AECA positive rate in HSPN was higher than that of without nephritis group. The level of serum SVCAM - 1 in IgA AECA positive children was higher than that of IgA AECA negative children. Conclusion SVCAM - 1 and IgA AECA may participate in the pathogegesis of HSP, and the level of molecule is correlated with the progress of HSP.

OBJECTIVETo investigate the protective effect and mechanism of curcumin derivatives B06 on myocardium from type 2 diabetic rats.

METHODSThirty-five male SD rats were randomly divided into 5 groups, normal control group (NC group), high fat group (HF group), high fat treatment group (FT group), diabetes mellitus group (DM group) and diabetes treatment group (DT group) (n = 7). The late four groups were fed with high fat food, after four weeks of high fat feeding, the rats from DM group and DT group were injected with low dosage of streptozocin intraperitoneally to induce diabetes mellitus, FT group and DT group were gavaged with curcumin derivatives B06 at the dosage of 0.2 mg/kg x d. The blood glucose and lipid were detected biochemically, blood insulin was assayed by ELISA and the insulin resistance index was calculated, the morphology of myocardium was observed by light and transmission electron microscopy, the protein expression of AMP-activated protein kinase alpha (AMPKalpha) and phosphorylated AMP-activated protein kinase alpha (p-AMPKalpha) in myocardium were tested by Western blot.

RESULTSThe level of blood glucose, lipid, insulin and the insulin resistance index were increased in HF group and DM group, but they were decreased after the treatment with B06. The expression of AMPKalpha and p-AMPKalpha were decreased, but they became increased after the treatment of B06. There were increased collagen fibers in interstitium and expansion of mitochondria in cytoplasm of myocardium from DM group, but they were ameliorated in B06 treatment group.

CONCLUSIONIt is suggested that B06 may relieve the damage of myocardium from type 2 diabetic rats and the increased expression of AMPKalpha and p-AMPKalpha may be involved in it.

OBJECTIVETo investigate the psychological impact of mastectomy on women with breast cancer.

METHODSQuestionnaires were answered by 90 patients after mastectomy for breast cancer. The data were collected and analyzed regarding the age, occupation, education, income and living place of the patients. Their psychological changes were compared and evaluated statistically using chi-square analysis.

RESULTSMastectomy caused psychological impact on half of the patients, which included fear of cancer, feeling of body incompleteness, inconvenience in working and social communication, less sexual act and low spirit. 79 percent of the patients considered breast reconstruction unnecessary. 54 percent did not know that the breast could be reconstructed. The patient feelings differed with the age, occupation, income and living place.

CONCLUSIONMastectomy hurts patient psychological health.

OBJECTIVETo investigate the effects and the mechanisms of the first-generation histamine H(1)-antagonist diphenhydramine and the second-generation histamine H(1)- antagonist fexofenadine on seizure development of pentylenetetrazole (PTZ)-induced kindling in rats.

METHODSThe first-or second-generation histamine H(1)-antagonists and/or histidine were ip injected in rats every 48 h, followed by a subconvulsive dose of PTZ (35 mg/kg). Then the behavioral changes were observed for 30 min after every injection of PTZ. The histamine content of brain was measured spectrofluorometrically.

RESULTCompared with the control group, diphenhydramine (5 mg/kg) significantly augmented the severity of seizure development of PTZ-induced kindling, whereas fexofenadine (5 mg/kg) had no marked influence. The effects of diphenhydramine were antagonized by histidine, the precursor of histamine.

CONCLUSIONSeizure development of PTZ-induced kindling is promoted by the first-but not the second generation histamine H(1)-antagonists via the blockade of brain histamine H(1)-receptor.

The study was aimed to investigate the expression of VEGF mRNA and VEGF protein in HL-60 cells treated with diallyl disulfide (DADS), and to explore the antileukemic mechanism of DADS in respect of VEGF production. Semi-quantitative RT-PCR and ELISA were used to detect the expression of VEGF mRNA and secretion of VEGF protein in HL-60 cell lines treated by DADS respectively. The results showed that the expression of VEGF mRNA and secretion of VEGF protein were found in HL-60 cells. The expression of VEGF mRNA and secretion of VEGF protein in HL-60 cells could be down regulated by treatment with 0.625, 1.25, and 2.5 microg/mL DADS for 48 and 72 hours and the effects had a dose dependent relationship (r > 0.9, P < 0.01). The differences between DADS treated HL-60 cell groups and the control group were statistically significant (P < 0.01), there were also statistically significant differences among three DADS-treated HL-60 cell groups (P < 0.05). It is concluded that DADS effectively inhibits the proliferation of human leukemia cell line HL-60 cells; DADS exerts its antileukemic effects by reduction of the expression of VEGF mRNA and VEGF protein secretion.

The effects of human insulin 70/30 and insulin lispro 75/25 were compared in improving postprandial blood glucose excursions in 106 patients with type 1 or 2 diabetes in a one-month,open-labelled,self- controlled trial .The results showed that treatment of diabetic patients with insulin lispro 75/25 significantly improved 2 h postprandial blood glucose excursion compared to pre-study with human insulin 70/30 (baseline) without any significant adverse events or sustained hypoglycemic episodes.These physiological benefits were associated with a patient preference for insulin lispro 75/25.

OBJECTIVE: To investigate the progression risk of atypical squamous cells of undetermined significance (ASCUS) with different clinical managements. METHODS: Women with their first diagnosis of ASCUS cytology were retrieved from the national cervical cancer screening database and linked to the national health insurance research database to identify the management of these women. The incidences of developing cervical intraepithelial neoplasia grade 3 and invasive cervical cancer (CIN3+) were calculated, and the hazard ratios (HRs) were estimated using a Cox proportional hazards model. This study was approved by the Research Ethics Committee of the National Taiwan University Hospital and is registered at ClinicalTrials.gov (Identifier: NCT02063152). RESULTS: There were total 69,741 women included. Various management strategies including colposcopy, cervical biopsies and/or endocervical curettage, and cryotherapy, failed to reduce the risk of subsequent CIN3+ compared with repeat cervical smears. Loop electrosurgical excision procedure/conization significantly decreased risk of subsequent CIN3+ lesions (HR=0.22; 95% confidence interval [CI]=0.07–0.68; p=0.010). Women in their 40s–50s had an approximately 30% risk reduction compared to other age groups. Women with a previous screening history >5 years from the present ASCUS diagnosis were at increased risk for CIN3+ (HR=1.24; 95% CI=1.03–1.49; p=0.020). CONCLUSION: In women of first-time ASCUS cytology, a program of repeat cytology can be an acceptable clinical option in low-resource settings. Caution should be taken especially in women with remote cervical screening history more than 5 years.

PURPOSE: We report herein major determinants and long- term outcomes of balloon dilatation (BD) for 27 pediatric patients with isolated native valvular pulmonary stenosis (VPS). MATERIALS AND METHODS: From May 1997 to May 2003, 27 pediatric patients with VPS (pressure gradients> or =40mmHg) were enrolled in this retrospective study. Single-balloon maneuver was applied in 26 patients, and double- balloon maneuver in 1. After BD, the pressure gradients were documented simultaneously by pullback maneuver by cardiac catheterization and echocardiography within 24 hours, at 1- month, 3-month, 1-year, and 4-to-10-year follow-ups. RESULTS: Before BD, the echocardiographic gradients ranged from 40 to 101mmHg (61+/-19, 55), and from 40 to 144mmHg (69+/-32, 60) by pressure recordings. After BD, the gradients ranged from 12 to 70mmHg (29+/-13, 27) by pressure recording (p<0.001), and from 11 to 64mmHg (27+/-12, 26) by echocardiography within 24 hrs (p<0.001). The ratios of the systolic pressure of the right ventricle to those of the left ventricle were 55 to 157% (89+/-28, 79%) before BD, and 30 to 79% (47+/-13, 42%) after BD p<0.001). Follow-up (7.7+/-5.7, 4.5 years) echocardiographic gradients ranged from 11 to 61mmHg (25+/-11, 24). Two patients did not have immediate success owing to infundibular spasm. Improved right ventricular compliance could be accounted for the ultimate success in these 2 patients. The ultimate successful rate was 100%. CONCLUSION: BD can achieve excellent long-term outcomes in the pediatric patients with isolated native VPS.

OBJECTIVE: To explore the laparoscopic partial gastrectomy and the indications. METHODS: Eighteen patients who underwent laparoscopic partial gastrectomy from August 2005 to May 2006 were analyzed retrospectively. RESULTS: Sixteen patients (including 6 with gastric cancer, 9 with duodenal ulcer, and 1 with gastric multiple polyps) underwent laparoscopic partial gastrectomy. The other two patients underwent an open surgical procedure (1 patient with the tumor size large than 6 cm, and the other patient with bleeding after loosening one clip). The rate of intraoperative subcutaneous emphysema was 5.88% (1/17), and no death occurred. The operation time was (285+/-30)min on average, the estimated blood loss was (130+/-50)mL, and the hospitalization was (11+/-4)d. One case of obstruction of distal loop happened after the surgery, and the rate was 6.25% (1/16). The patients were followed up for 1 approximately 9 months postoperatively. Trocar puncture-site metastases occurred in one patient. CONCLUSION Laparoscopic partial gastrectomy is safe and feasible with skillful laparoscopic technique and with restricted indications, and the surgical outcome may be similar to that of the open surgery.

OBJECTIVETo evaluate the effect of titrated target-controlled infusion with propofol and remifentanil on anesthetics consumption and anesthesia depth in patients undergoing elective laparoscopic colorectal surgery.

METHODSSixty ASA I-III patients for elective laparoscopic colorectal surgery were enrolled. Titrated target-controlled infusion (TCI) with propofol and remifentanil was performed. Plasma concentration of the drugs was administered by titrated method to maintain bispectral index (BIS) in the range of 40-60 with systolic blood pressure (SBP) fluctuation within 20% of the basic value. BIS, SBP, plasma concentration of propofol and remifentanil were recorded at different time points. Awareness during operation was inquired postoperatively.

RESULTSDuring the entire anesthesia period, the blood pressure was stable and BIS was maintained less than 60. There was no awareness during operation. The plasma concentrations (95% confidence interval) for TCI of propofol and remifentanil were 2.55-2.65 mg/L and 4.09-4.26 μg/L respectively when existing surgical stimulation during anesthesia, and the plasma target concentration of propofol was lower than the recommended dosages.

CONCLUSIONTitrated target-controlled infusions with propofol and remifentanil for elective laparoscopic colorectal surgery can maintain proper anesthesia depth and reduce the drug consumption.
