ObjectiveTo investigate the application of remifentanil and etomidate target controlled infusion anesthesia in operation for esophageal cancer and observe its effects on hemodynamics.Methods Sixty patients of esophageal cancer were divided into control group and observation group by random digits table with 30 cases each.The observation group was given remifentanil and etomidate for induction of the general anesthesia,while the control group was given remifentanil and propofol.The changes of mean arterial pressure(MAP),heart rate(HR),postoperative spontaneous breathing recovery time,waking time,extubation time were observed.ResultsMAP after induction was lower than that lying for 10 minutes after entering operating room in two groups (P ＜ 0.05),and observation group was lower than control group (P ＜ 0.05).MAP,HR after 5 minutes extubation were higher than those lying for 10 minutes after entering operating room(P ＜ 0.05 ),and observation group was higher than control group (P ＜ 0.05 ).The postoperative spontaneous breathing recovery time,waking time,extubation time in observation group [ (5.3 ± 1.5 ),(6.4 ± 2.1 ),(8.4 ± 2.5 ) min ] were shorter than those in control group [ ( 16.9 ± 8.7 ),(21.3 ± 7.7),(23.7 ± 5.8)min],and there were significant differences (P ＜0.05).ConclusionRemifentanil and etomidate target controlled infusion anesthesia in operation for esophageal cancer can maintain the stability of blood concentration and hemodynamics,shorten the recovery time,and improve the quality of anesthesia recovery and safety.

Osteoporosis is a common metabolic bone disease in the aging population society. The incidence is increasing during these years. Elderly people especially postmenopausal women are of greatest susceptibility. Fracture and other complications caused by osteoporosis may affect patients' life span and the quality of life. It also increased medical costs. The principles of managing osteoporosis are understanding the risk factors and susceptible population; appropriate evaluating bone mass and multidisciplinary approach. The present paper reviewed the update of epidemiology, pathophysiology, risk factors, evaluation methods and management of this disease.

Multidisciplinary team(MDT)diagnosis and treatment of colorectal cancer has been adopted by plenty of hospitals as a kind of effective comprehensive therapy.Compared with the traditional diagnosis and treatment methods,MDT diagnosis and treatment achieve standardization of diagnosis and treatment and technical promotion through specialization of the team to ensure better treatment and prognosis of patients.However,MDT diagnosis and treatment of colorectal cancer is not perfect,which can be limited by two aspects of hospitals and patients and can realize maximum utility with knowledge of its characteristics.This article will try to explore the distribution and usage of the resource in MDT diagnosis and treatment of colorectal cancer,the advantages over the traditional cure methods and the limits.

Objective To summarize the efficacy of epirubicin chemotherapy by intra-iliac arteral infusion for the high risk patients of postoperative bladder cancer. Methods Eighty-six patients with the bladder cancer at high risk of recurrence who had undergone the bladder-sparing surgery were divided into two groups.Thirty-one patients were treated by intra-iliac arterial infusion chemotherapy of epirubicin and the remaining 55 patients had no chemotherapy.An analysis on recurrence related factors was made by multivariate Cox regression analysis models.And Kaplan-Meier curves were compared using the log-rank test on the disease-free between the two groups. Results Multi-recurrence associated with a higher grade and postoperative intra-iliac arterial infusion chemotherapy of epirubicin were significantly important factors,the former being risk factor and the latter being protective factor of cancer recurrence in bladder respectively.The recurrence of 9 in 31 patients (29%) with intra-iliac arterial infusion chemotherapy of epirubicin was significantly lower than that of 30 in 55 patients (54%) without chemotherapy ( P

Objective To evaluate the learning curve in percutaneous nephrolithotomy under the guidance of B ultrasonography.Methods From January 2006 to July 2007,totally 60 cases of percutaneous nephrolithotomy were performed under the guidance of B ultrasonography by a single urologist.The patients were divided into 6 groups according to the date of the operation(10 cases in each).The time for setting the renal access and the stone-free rate were compared among the groups.Results The time for setting the renal access was(15.0?2.7),(14.0?2.1),(10.2?1.2),(5.8?0.7),(7.5?1.2),and(6.6?0.9)minutes respectively in group 1 to 6.ANOVA analysis showed significant difference among the groups(F=5.734,P=0.000).Significant difference was detected between groups 1 and 4(q = 5.655,P

Objective To evaluate the efficacy and safety of ultrasonography-guided percutaneous nephrolithotomy(PCNL).Methods Between May 2006 and June 2008,110 patients underwent PCNL by a single urological team at our hospital.The clinical data of the patients were retrospectively reviewed.Of the cases,supracostal access(the 11th intercostal space) was made in 62 patients(supracostal group),and subcostal access was obtained in 48 patients(subcostal group).Forty-five patients in the supracostal group(45/62) and 36 of the subcostal group(36/48) received CT three dimensional reconstruction.Results The stone free rate of the supracostal group was 72.6%(45/62),while that of the subcostal group was 60.4%(29/48;?2=1.818,P=0.178).The mean operation time of the supracostal group was(78.6?5.1) min,while that of the subcostal group was(102.4?7.1) min(t=-20.454,P=0.000).There was one patient in each group received blood transfusion.One patient in the supracostal group had pneumothorax and recovered uneventfully by conservative treatments.Conclusion Ultrasonography-guided PCNL via the supracostal approach is effective and safe with short operation time.

Objective To determine the signal pathway of specifically expressed oncostatin M(OSM) in lens inducing retinal degeneration in transgenic mice. Methods A sequence-truncated OSM cDNA (661 bp) of mice was linked to ?A-crytallin promoter, and was micro-injected into unicellular embryo to set up the model of transgenic mice. Reversal transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA expression of gp130/OSMR? receptor in the retinae of OSM transgenic and non-transgenic mice. Rabbit anti-phosphorylated STAT-3 antibody was used to detect the protein expression of phosphorylated STAT-3,and mouse anti-cytochrome C antibody was used to detect the distributing of cytochrome C in retinae. Results Expression of gp130/OSMR? mRNA was found in retina of non-transgenic mice. At the 17.5th day in the embryonic stage, significant accumulation of the phosphorylated STAT-3 was detected in the retinal nucleolus in OSM transgenic retina. At the first day after birth, intensive staining of cytochrome C in OSM transgenic retina was found. Conclusions specifically expressed OSM in lens may act on gp130/OSMR? receptor in retinae, activate STAT-3, and cause the release of cytochrome C from mitochondria, which eventually induces widespread retinal degeneration.
