Objective To explore the effects of PSE on hemodynamics and Liver function in LCPH. Methods 30 patients with LCPH are treated by PSE. The hemodynamics changes of patients with LCPH are evaluated with color Doppler diasonograph. The changes of main clinical features which is related to LCPH , serum ALT and albumn were investigated . Results The hemodynamics indexs of LCPH are all changed significantly (P0. 05) between four and two weeks after PSE. But the main symptoms, signs of LCPH and liver function are improved after PSE . Conclutions PSE plays an important role in hemdynamics and liver function of LCPH. After PSE, Portal hypertension decreases effectively and liver function is improved.

Objective To compare the treatment effects,dosimetry,and toxicities to organs at risk of intensity-modulated radiation therapy (IMRT) and 3-dimentional conformal radiotherapy (3DCRT) plans for cervical carcinoma patients with recurrence and metastasis. Methods 62 cervical carcinoma patients with recurrence and metastasis were analyzed retrospectively, and divided into two groups including intensitymodulated radiation therapy group (n=29) and 3-dimentional conformal radiotherapy group (n=32).Patients were performed with 6 MV-X ray.The regimen was 1.8-2.2 Gy/f,1 f/d,18-33 times in total.Prescribed dose was 40-60 Gy and median dose was 52.8 Gy. At the same time for the IMRT group 29 cases were performed with 3DCRT, which was designed using the same prescribed dose to compare radiation dose distributed in organs at risk (OAR).Results The maximum dose of the two plans showed that bladder and small intestine in IMRT plans were lower than that in 3DCRT (P<0.05), showing the IMRT's protective advantage. The maximum dose of PTV in IMRT plans were significantly higher than 3DCRT (P<0.05). In the group of IMRT plans, the overall 1-,2-,and 3-year survival rates were 65.5 %(19/29), 42.1%(8/19), and 25.0 %(2/8),respectively,the median survival time was 19 months,of 28 deaths,21 patients died of tumor progression,7 patients died of distant metastases.In the group of 3DCRT plans,the overall 1-,2-,and 3-year survival rates were 60.6 %(20/33),35.0 %(7/20),and 14.3 %(1/7),respectively,the median survival time was 17 months,of 32 deaths, 24 patients died of tumor progression, 8 patients died of distant metastasis. There were no significant differences in overall 1-, 2-, and 3-year survival rates between the two groups (P>0.05). The incidence rate of toxicity in the IMRT plans was significantly lower than that in the 3DCRT plans, especially for patients with Ⅰ level and Ⅱ level.Conclusion The treatment effects of the IMRT plans are better than the 3DCRT plans for cervical carcinoma patients with recurrence and metastasis. IMRT plans can improve radiation dose in tumors and reduce the dose distributed in normal issue and reduce the incidence of the side effect.

Objective:To evaluate the efficacy of remimazolam-propofol-sufentanil for anesthesia in patients undergoing painless gastroscopy.Methods:Eighty American Society of Anesthesiologists physical statusⅠor Ⅱ patients, aged 20-59 yr, weighing 44-69 kg, scheduled for elective painless gastroscopy, were divided into 2 groups ( n=40 each) using a random number table method: remimazolam-propofol-sufentanil group (group RPS) and propofol-sufentanil group (group PS). The patients in group RPS received successive intravenous injection of sufentanil 0.1 μg/kg, remimazolam 0.15 mg/kg and propofol (at a rate of 4 mg/s). The patients in group PS received intravenous injection of sufentanil 0.1 μg/kg and propofol (at a rate of 4 mg/s). When Observer′ s Assessment of Alertness/Sedation Scale score was 0, gastroscopy was performed.The consumption of propofol, time of anesthesia, time for gastroscopy, emergence time and discharge time were recorded.The number of intraoperative assisted respiration cases, body movement and occurrence of adverse reactions at the time of discharge were observed. Results:Compared with group PS, the consumption of propofol was significantly decreased, and the time of anesthesia, emergence time and discharge time were shortened in group RPS ( P<0.05). There was no significant difference in the time for gastroscopy, the number of intraoperative assisted respiration cases, body movement and the occurrence of adverse reactions at discharge time between the 2 groups ( P>0.05). Conclusion:Remimazolam-propofol-sufentanil produces better efficacy for anesthesia than propofol-sufentanil in patients undergoing painless gastroscopy.
