Objective To evaluate the effect of pituitrin and nursing for patients with vasoplegic syndrome after cardiopulmonary bypass. Methods 38 patients with cardiopulmonary bypass after open heart operation were divided into two groups with 19 cases in each group according to odd-nunbered and even-numbered days, the PT group was given pituitrin treatment, the NE group was given norepinephrine treatment. Heart rate, MAP, urine volume were recorded at 0.5, 1, 2, 6, 12 and 24 hours after drug therapy.Mechanical ventilation time, ICU stay time,hepatic and renal function and clinical symptom were compared between the two groups. Results MAP and urine volume increased significantly at 0.5 hour after pituitrin therapy. MAP increased from (55.33±4.10)mmHg to (67.34±4.13)mmHg. Urine volume increased from (0.08±0.02)ml·kg-1·h-1 to (1.84±1.21)ml·kg-1 ·h-1 MAP and urine volume also increased at other time points. In the NE group, MAP increased at 1h after treatment. Both MAP and urine volume increased at 2h and later after norepinephrine treatment. One death happened in the NE group. Compared with the NE group, the PT group was associated with lower ICU stay, mechanical ventilation time and 24h serum LAC.Liver and kidney function, myocardial infarction, nausea and vomiting, and other side effects were not different between the two groups. Conclusions Application of low-dosage pituitrin is rapid, efficient and safe treatment for patients with vasoplegic syndrome after open heart operation.

Objectives　To investigate the relationship between homocysteine (Hcy), folic acid, vitamin B12(VitB12),lipids and the carotid artery atherosclerosis(CAAs) and the significance of their levels in predicting cardiac and cerebral vascular events of older patients. Methods　Both sides of the common carotid artery and internal carotid artery were measured by B-mode ultrasound in 74 examinees in A, B, C, and D groups and a control group. With fasting serum, cholesterol, triglyceriade, apolipoprotein AI(Apo AI), apolipoprotein B (Apo B), lipoprotein (a) ［Lp(a)］, creatinine, glucose, folic acid, Vit B12 and Hcy were detected. Results　When carotid artery atherosclerosis became severer, serum Hcy was higher. The levels of the control and A, B, C, D groups were (10.2±3.6) μmol/L, (11.5±4.4) μmol/L, (17.9±4.5) μmol/L, (24.7±10.3) μmol/L, and (41.4±22.3) μmol/L respectively. SNK test showed a significant difference between D and other groups (P>0.05). Folic acid and Vit B12 were negatively correlated with the severity of carotid artery atherosclerosis, but only A and D groups showed statistical significance. Spearman correlation coefficient showed that serum Hcy had significant negative correlation with folic acid and Apo AI(P=0.035 and P=0.000).Multiple linear regression analysis between CAAs and various risk factors showed Apo AI had negative correlation, but Apo B, Lp(a) and Hcy had positive correlation with CAAs, especially Hcy(P=0.009).Conclusion　Hyperhomocysteinaemia is an important risk factor of artery atherosclerosis and the degree of CAAs is highly correlated with Hcy concentration. Hcy, Apo AⅠ,Apo B, Lp(a) are sensitive and reliable indexes for evaluating and predicting CAAs.

Objective To evaluate the clinical significance of laparoscopic resection for large intramural hysteromyoma. Methods A retrospective analysis was made concerning 42 cases of single intramural hysteromyoma as large as 6～10 cm in diameter: 24 cases underwent laparoscopic hysteromyomectomy and 18 cases received open resection. Intra- and post-operative parameters between the two groups were compared. Results All operations in the two groups were successfully completed without complications. The operative time was significantly longer in the laparoscopic group (89.0?26.9 min) than that in the open group (63.3?20.1 min) ( t=3.400,P =0.002). No statistical difference was observed in the intraoperative blood loss between the laparoscopic group (93.6?65.9 ml) and the open group (100.0?48.7 ml) ( t=-0.347, P=0.731) . The analgesic requirement was less in the laparoscopic group (2 out of 24 cases ) than that in the open group (9 out of 18 cases) ( ? 2 =7.208, P =0.007). The time to first flatus was shorter in the laparoscopic group (23.5?11.3 h) than that in the open group (32.0?13.6 h) ( t=-2.211, P =0.033). The postoperative pyrexia rate was significantly lower in the laparoscopic group (2/24) than that in the open group (7/18) ( ? 2=4.033, P =0.045). Conclusions Laparoscopic resection for larger intramural hysteromyoma is safe and reliable. As compared with open hysteromyomectomy, it offers more rapid recovery and lower postoperative pyrexia rate, as well as the same amount of blood loss. Its prolonged operative time may be associated with the relatively large size of the hysteromyoma.

Objective To study the influence of artesunate (Akt) on the proliferation and apoptosis of human head and neck squamous cell carcinoma (HNSCC), and to explore its molecular mechanism thereof. Methods The HNSCC cell line,UM-SCC-10A cells, was cultured in vitro. The Inhibitory concentration 50 (IC50) was examined by MTT assay. The cell mor?phological changes were observed under inverted light micro-scope after being interfered by 0, 2.5, 5, 10, 20 and 40μmol/L Akt. Cell cycle changes and apoptosis were measured by flow cytometry. And the expression of cell cycle regulators and apop?totic associated protein were detected by Western blot assay. Results MTT assay demonstrated that Akt significantly inhib?ited the proliferation of UM-SCC-10A cells in dose-dependent manner. After UM-SCC-10A cells were treated with Akt for 48 h, IC50 was 15.01μmol/L. Morphological changes of cell apoptosis such as karyopyknosis and conglomeration were ob?served by Hoechst 33258 staining. Flow cytometry showed that the apoptosis was associated with cell cycle arrest during the G1 phase. Western blot analysis showed that p53 and p21 protein was up-regulated and Cyclin D protein was down-regulat?ed. Furthermore, results revealed that Bcl-2 associated X protein induced by a mitochondrial pathway, cytochrome C and caspase-3 were up-regulated, and Bcl-2 and procaspase-3 were down-regulated. The mitochondrial membrane potential was reduced. Conclusion Artesunate can induce apoptosis of UM-SCC-10A cells via a mitochondrial pathway, which was associated with cell cycle arrest in the G1 phase. As a result, artesunate has an obvious inhibitory effects on proliferation of UM-SCC-10A cells.

0.05).FVC increased significantly in week 6 and 12(t=2.762,P =0.008;t=2.255,P =0.029,respectively).There was no statistical significance in FEV_1/FVC between two groups.IC increased significantly in week 6 and 12(t =3.204,P =0.002;t =3.109,P=0.003,respectively).Conclusion Inhaling tiotropium increases IC in patients with stable COPD.As lung function targets judging limit extent of airflow in patients with COPD,FEV_1/FVC and FEV_1(%)are not sensitive in evaluating therapeutic effect of bronchodilators.IC is more reliable than other targets in evaluating therapeutic effect of bronchodilators.
