To compare the short-and long-term effect of two minimal invasive surgical therapies including keyhole approach endoscopic surgery(KAES)and stereotactic aspiration plus urokinase(SAU)in treating basal ganglia hypertensive intracerebral hemorrhage(hICH). The clinical data of 117 hICH patients(63 received KAES and 54 received SAU)were retrospectively analyzed.The operation time,blood loss during surgery,and drainage time were compared between two groups.The residual hematoma volume,hematoma clearance rate(HCR),Glasgow coma scale(GCS)score,and National Institute of Health Stroke Scale(NIHSS)score were recorded at baseline and in the ultra-early stage,early stage,and sub-early stage after surgery.The 30-day mortality and serious adverse events were assessed and the 6-month modified Rankin scale(mRS)score was rated. Baseline data showed no significant difference between these two groups.Compared with the SAU group,the KAES group had significantly longer operation time,more intraoperative blood loss,and shorter drainage time(all <0.001).In the ultra-early stage after surgery,HCR was significantly higher in the KAES group(<0.001),whereas in the early and sub-early stage,HCR showed no significant differences(all >0.05).In the ultra-early and early stage,the GCS and NIHSS scores showed no significant differences between two groups(all >0.05),whereas in the sub-early stage,the NIHSS score was better in the SAU group(=0.034).The 30-day mortality and incidences of serious adverse events showed no significant difference(all >0.05).The good recovery(mRS≤3)at 6-months follow-up showed no significant difference between the two groups(=0.413). Both KAES and SAU are safe and effective in treating basal ganglia hICH.In the ultra-early stage after surgery,KAES achieves better residual hematoma volume and HCR,and patients undergoing SAU quickly catch up.The short-and long-term effectiveness of SAU is comparable or even superior to KAES.

OBJECTIVEThis study examined the levels of exhaled nitric oxide (eNO) and peripheral blood eosinophils (EOS) as well as the correlation between the two markers in children with bronchial asthma (AS),AS complicated by allergic rhinitis (AS/AR) and chronic cough variant asthma (CVA), in order to explore the value of eNOS detection in children with AS.

METHODSThe eNO level was measured using light-emitting electrochemical photometry in 12 children with AS, 29 children with AS/AR and 10 children with CVA. Peripheral blood EOS was counted by blood cell counter (Coulter JT). Forced expiratory volume in one second (FEV1) was assessed by lung function measurement. Thirty children without atopic disease and acute respiratory infection as well as without a family history of atopic diseasea served as the control group.

RESULTSThe levels of eNO and blood EOS in the AS, the AS/AR and the CVA groups were significantly higher than those in the control group (p<0.01). The AS/AR group showed increased levels of eNO (50.3 + or - 6.7 ppb) and EOS (5.9 + or -4.2 x 109 ) compared with the AS (30.5 + or - 8.8 ppb and 4.2 + or - 3.2 x 109 respectively) and the CVA groups (26.0 + or - 3.2 ppb and 3.7 + or - 6.9 x 109 respectively) (p<0.05). There were no significant differences in eNO and EOS levels between the AS and the CVA groups. The eNO level was positively correlated with the EOS level (r=0.51, p<0.05), but not with FEV1 (r=0.144, p>0.05) in the AS group.

CONCLUSIONSNO is highly expressed in children with symptoms of atopy and can reflect the levels of eosinophilic airway inflammation in children with AS.

OBJECTIVETo observe the effect of bone marrow mesenchymal stem cell transplantation on postangioplasty aortic restenosis in rats.

METHODS48 SD rats were randomly divided into normal control group, balloon injury group, balloon injury and MSCs transplantation group. MSCs were pre-labeled by DAPI (25 microg/ml) and then infused into aorta through the balloon catheter (MSCs 2 x 10(6)/animal). Thoracic aorta were taken for histological examination (frozen and paraffin sections) at 1, 2, 6 weeks post angioplasty, respectively. DAPI labeled MSCs were detected under immunofluorescence microscopy. Expressions of c-kit, proliferating cell nuclear antigen (PCNA), smooth muscle alpha-actin (alpha-SMA) in aorta were determined by immunocytochemistry using related antibodies.

RESULTSThe DAPI-labeled MSCs could be detected on impaired intimae and alpha-SMA expression was seen in these cells 1 weeks after MSCs transplantation. Similar weak c-kit expression in neointima was found in both injury and transplantation group at 2 weeks (P > 0.05). Expressions of PCNA and alpha-SMA in the neointima were significantly higher in transplantation group than in injury group at 2 weeks. Intima/tunica media area ratio and luminal stenosis ratio were significantly increased in transplantation group than injury group at 6 weeks (all P < 0.05).

CONCLUSIONBone marrow MSCs transplanted post aortic angioplasty could home to serious wounded aortic intima, differentiate into smooth muscle like cells, promote neointima cellular proliferation and aggravate postangioplasty aortic restenosis in rats.

OBJECTIVETo investigate the efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) in the treatment for obesity and type 2 diabetes mellitus (DM).

METHODSTwenty-one cases of obesity and 9 cases of type 2 DM received the LRYGB. Weigh changes, excess body weight lose rate (EWL%) and blood glucose level were measured after surgery and occurrence of complications was observed postoperatively.

RESULTSLRYGB procedures in all the 30 cases were successfully performed with no conversion to open surgery. Average operation time was 168 minutes (110-270 mins), volume of blood loss during the surgery was 24.0 ml (10-75 ml). Twenty-one cases of simple obesity received follow-up from 2 months to 5 years. Body weight and BMI decreased significantly in one month [(85.1+/-10.1) kg vs (97.2+/-15.0) kg, 31.2+/-2.2 vs 35.3+/-3.5, both P<0.01] and to a minimal level in 2 to 3 years [(66.8+/-9.2) kg, 24.3+/-1.1], and then maintained at this level. EWL% was correspondingly higher (all P<0.05). Nine type 2 DM patients were followed up for 3 to 8 months, fasting blood glucose and blood glucose OGTT2 hours decreased significantly [(5.9+/-1.4) mmol/L vs (12.6+/-2.6) mmol/L, (7.8+/-1.4) mmol/L vs (17.8+/-4.1) mmol/L, both P<0.05], of whom 4 patients with obesity decreased in BMI significantly (P<0.05), and 5 patients without obesity had no significant changes in BMI (P>0.05). Five cases (16.7%) had postoperative complications, including 1 case of death due to acute fulminant pancreatitis, 1 case of mesenteric hiatal hernia with obstruction in line for reoperation, and the other 3 cases of healing by conservative therapy.

CONCLUSIONSTreatment of obesity and type 2 DM by LRYGB surgery is feasible with significant short term result. Long term outcome needs further observation.

OBJECTIVETo observe the changes of plasma renin activity, antidiuretic hormone and brain natriuretic peptide in chronic heart failure (CHF) and their correlation with hyponatremia.

METHODSPlasma levels of PRA, ADH, and BNP were measured by radioimmunology in 76 CHF patients. Forty-one out of 76 CHF patients with hyponatremia and 35 CHF patients without hyponatremia were identified by serum sodium. The rates of rehospitalization within 3 months were compared in two groups.

RESULTSLevels of plasma renin activity, ALD, and BNP in CHF patients with hyponatremia were notably higher than those in patients without hyponatremia classified by New York Heart Association (NYHA) grade II - IV: PRA [(2.7 +/- 1.0) ng.ml(-1).h(-1) vs. (1.8 +/- 0.7) ng.ml(-1).h(-1), (4.3 +/- 1.2) ng.ml(-1).h(-1) vs. (3.0 +/- 0.9) ng.ml(-1).h(-1), (5.6 +/- 1.3) ng.ml(-1).h(-1) vs. (3.5 +/- 1.1) ng.ml(-1).h(-1), respectively, P < 0.05], ADH [(59.7 +/- 17.4) ng/L vs. (48.6 +/- 15.3) ng/L, (68.4 +/- 17.6) ng/L vs. (56.3 +/- 19.2) ng/L, (75.3 +/- 20.0) ng/L vs. (51.4 +/- 16.2) ng/L, respectively, P < 0.05] and BNP [(276.4 +/- 75.2) ng/L vs. (185.3 +/- 55.3) ng/L, (380.1 +/- 113.6) ng/L vs. (258.5 +/- 62.1) ng/L, (564.0 +/- 125.2) ng/L vs. (405.3 +/- 102.9) ng/L, respectively, P < 0.05]. In the simple regression analyses, hyponatremia was negative correlated with PRA, ADH and BNP (r = -0.31, P < 0.05; r = -0.28, P < 0.05, r = -0.80, P < 0.01). The rate of rehospitalization within 3 months in hyponatremia group was higher than that in control group.

CONCLUSIONSThere is relation of hyponatremia to the changes of plasma renin activity, antidiuretic hormone and brain natriuretic peptide in chronic heart failure. Hyponatremia may accelerate the excretion of plasma PRA, ADH and BNP in chronic heart failure. Neuroendocrine activation in patients of congestive heart failure with hyponatremia is higher than that of normal natremia group.

OBJECTIVETo compare short-term postoperative outcomes between antecolic and retrocolic laparoscopic Roux-en-Y gastric bypass(LRYGB).

METHODSForty obesity patients were admitted into The First Affiliated Hospital of Jinan University from March 2008 to July 2010. All patients were randomly assigned to undergo antecolic (group A, 20 cases) and retrocolic (group B, 20 cases) gastroenteric anastomosis. Short-term outcomes were compared.

RESULTSLRYGB procedures were successfully performed in all the 40 patients. There were no significant differences between the two groups in estimated blood loss during surgery, time to flatus passage, time to resumption of oral intake, or length of postoperative hospital stay. The operation time was longer in group B than that in group A [(163.4±28.1) min vs.(131.8±22.7) min, P<0.05]. There were no patients developed internal hernia or anastomotic leakage in either group. Comparison of short-term gastrointestinal symptoms after surgery showed no statistical significance.

CONCLUSIONSAlthough retrocolic procedure may be closer to anatomical structure, antecolic and retrocolic anastomosis have comparable short-term outcomes after surgery. Further study is warranted to investigate long-term outcomes.

Aim To investigate the protective effect of 1, 8-Cineole on the injury of human aortic endothelial cells (HAECs) induced by high glucose (HG) via regulating autophagy. Methods Cells were incubated with different doses of 1, 8-Cineole followed by exposing to HG for 60 h, and MTT assay was used to analyse cell viability, lactate dehydrogenase (LDH) was used to detect cytotoxicity, and Western blot was used to detect Beclin1, LC3-II/I, p62, caspase-3 and caspase-9 expressions. Autophagy inhibitor (chloroquine, CQ) was treated on HAECs, and the expressions of Beclinl, LC3-II/I, p62, caspase-3 and caspase-9 were measured by Western blot. Results 1, 8-Cineole increased cell viability, reduced the content of LDH, activated autophagy and inhibited apoptosis. Compared with control group, the expression of Beclinl, LC3-II/I, p62, caspase-3 and caspase-9 in CQ group increased. Simultaneously, the expression of above-mentioned between CQ + HG group and CQ + HG + CH group. Conclusions 1, 8-Cineole has protective effect on the injury of HAECs induced by high glucose, and its effect is related to improving autophagy flux.

OBJECTIVETo evaluate the feasibility of three-dimensional pseudo-continuous arterial spin label (3D pCASL) non-contrast enhanced perfusion imaging applied to head and neck tumors in high-field MR and detect the effects of different postlabeling delay (PLD) time on image quality and the reliability of repeated measurements of tumor blood flow (BF) in different 3D pCASL groups.

METHODSIn this prospective study,all the 25 patients received neck 3D pCASL non-contrast enhanced perfusion examinations in a 3.0 T MR system by using an 8-channel head and neck joint coil. Conventional T1-weighted (TIWI) and T2-weighted imaging (T2WI) were performed firstly. Finally,three 3D pCASL with different PLD time [ASL1(PLD1=1525 ms),ASL2 (PLD2=2025 ms), ASL3(PLD3=2525 ms)] were acquired. Patients' perfusion-weighted images acquired from different 3D pCASL sequences underwent the analysis of signal to noise ratio (SNR) and contrast noise ratio (CNR) for tumors. Two observers performed the qualitative assessments on spiral artifacts and vascular artifacts of perfusion-weighted images from different 3D pCASL sequences. Blood flow (BF) of tumors from different 3D pCASL sequences were measured by the two observers respectively for the first time and by observer 2 for the second time.

RESULTSSeventeen enrolled patients (age:50.1 ± 12.7 years,M/F=10:7) with histopathologic.

RESULTSunderwent the evaluation of image quality and measurements of BF values. The SNRs and CNRs of ASL1,ASL2, and ASL3 showed a descending trendency. SNRs (P=0.011) and CNRs (P=0.009) of ASL1 were significant higher than those of ASL3. There was no significant difference of scores of spiral artifacts among the three ASL groups (P=0.932). The scores of vascular artifacts of ASL1,ASL2,and ASL3 showed a descending trendency,also. And scores of ASL1 was significant higher than that of ASL3(P=0.000). The intraclass correlation coefficient (ICC) of intre-and intraobserver were high (ICC>0.9). Although the BF values of ASL1,ASL2, and ASL3 showed an ascending trendency,there was no significant difference among the three groups (P=0.977).

CONCLUSIONSThe 3D pCASL no-contrast enhanced perfusion MR imaging can be used for head and neck tumor. The image quality of perfusion weighted images and reliability of BF measurements were satisfied. The 3D pCASL series with PLD of 1525 ms and 2025 ms have better image quality than PLD of 2525 ms. And BF values do not show significant statistic difference among the three groups. Therefore, 3D pCASL series with PLD of 1525 ms and 2025 ms are more suitable for the perfusion imaging of head and neck tumors

To establish HPLC-MS/MS method for simultaneous determination of daphnetin, daphnoretin, and daphneticin in rat plasma after oral and intravenous administration of Daphne giraldii extract, and then use them in the calculation of pharmacokinetic parameters. Six sprague-dawley rats received intragastric administration of D. giraldii extract (daphnetin, daphnoretin and daphneticin were 88.40, 3.24 and 4.28 mg•kg⁻¹, respectively). Their drug plasma concentration was determined by LC-MS/MS with schisandrin as an internal standard to draw plasma concentration-time curve. The pharmacokinetic parameters were calculated by Kinetica 4.4. The results showed that the linear range was 5-1 000 μg•L⁻¹ for daphnetin, daphnoretin and daphneticin, and the method ological test showed conformance to the requirements.The intraday and inter-day variable coefficients (RSD) were both less than 15.0%, indicating that both of legitimate precise and accuracy were consistent with the analysis requirements of biological samples. For daphnetin, the pharmacokinetic parameters Tmax, Cmax, AUC0-t, T1/2 and MRT were 4 h, 858.96 μg•L⁻¹, 10 566.4 μg•L⁻¹•h, 5.19 h and 9.43 h, respectively. For daphnoretin, the pharmacokinetic parameters Tmax, Cmax, AUC0-t, T1/2 and MRT were 2.92 h, 178.00 μg•L⁻¹, 905.89 μg•L⁻¹•h, 3.50 h and 6.95 h, respectively. For daphneticin, the pharmacokinetic parameters Tmax, Cmax, AUC0-t, T1/2 and MRT were 2 h, 36.67 μg•L⁻¹, 355.11 μg•L⁻¹•h, 4.95 h and 8.27 h, respectively. The LC-MS/MS analysis method established in this study was proved to be so accurate and sensitive that it can be applied to the pharmacokinetic study of daphnetin, daphnoretin and daphneticin.
