Objective To investigate the effect of diabetes mellitus on neuromuscular blocking effect of cisatracurium in patients. Methods Forty ASA Ⅱ patients, aged 30-64 yr, weighing 44-90 kg, scheduled for neurosurgical operation under general anesthesia, were assigned into 2 groups (n = 20 each): type 2 diabetes mellitus group (group D) and non-diabetes mellitus group (group ND). General anesthesia was induced with midazolam,fentanyl and etomidate. Neuromuscular block was assessed with Epoch XP nerve electrophysiology monitor. A train-of-four stimulation of ulnar nerve was used. Cisatracurium 0.15 mg/kg was injected intravenously over 5 s after T1 was maintained at 100%. Tracheal intubation was performed after the onset of the muscle relaxant. Anesthesia was maintained with iv infusion of propofol 4-8 mg· kg - 1 · h - 1 and remifentanil 0.1-0.3μg· kg - 1 · min - 1. The effect of inmbation was evaluated and graded. The onset time, clinical duration, recovery time and recovery index were recorded. Results The onset time was significantly longer in group D than in group ND ( P < 0.05). There was no significant difference in the clinical duration, recovery time and recovery index and intubation effect grade between the two groups ( P > 0.05). Conclusion Diabetes can prolong the onset time of cisatracurium, but has no effect on the clinical duration and recovery time.

With the increase of morbidity and mortality, pancreatic cancer will not only become one of the leading causes of death in China, but also a major public health problem in the world. New onset cases of pancreatic cancer all around the world are expected to increase year by year. The prognosis of patients with pancreatic cancer is poor. The 5-year survival rate is only about 6%. The major reason for the poor prognosis is the lack of typical clinical symptoms in the early stage of disease, which makes it difficult to detect and control its relevant recurrence and metastasis. Moreover, lack of effective chemotherapy drugs and resistance to existing chemotherapy drugs are also important reasons for its dismal status. Radical resection surgery is still the most effective treatment. However, even after radical resection surgery, early recurrence and distant metastasis are still the main problems that bother patients. This article reviews recent high quality studies on pancreatic cancer including epidemiological investigation, advances in basic research, and clinical treatment.

ObjectiveTo observe the effects of catalpol, the effective component of Rehmanniae Radix, on atrionector cell apoptosis andβ-tubulin in vitro rabbit injured by simulated ischemia reperfusion;To explore the mechanism of treating sick sinus syndrome.MethodsAtrionector cells were collected from newborn rabbits. Cells were divided into 5 groups:normal group, model group, catalpol high, medium and low dose groups. Anoxia and aglycaemia were established to simulate ischemia. Atrionector cellular damage models were established by recovering the supply of oxygen and sugar. Normal control group and model group were given the same volume of culture medium, while catalpol high, medium and low dose groups were given medicine with relevant concentrations (100, 20, 10μg/mL, respectively). ELISA, FCM, laser scanning confocal microscopy were used to observe apoptosis rate andβ-tubulin of atrionector in each group.Results Apoptosis rate of the model group was obviously higher than the normal group (P<0.01), andβ-tubulin cleavage was obvious. Apoptosis rate in catalpol high, medium and low dose groups were significantly lower than that of the model group (P<0.01);β-tubulin structure were significantly more complete compared with the model group;the fluorescence intensity was significantly higher than that of model group (P<0.01).Conclusion Catalpol can inhibit atrionector cellular apoptosis caused by simulated ischemia reperfusion. Its protective effects on atrionectorβ-tubulin may be the mechanism of the treatment of Rehmanniae Radix for sick sinus syndrome.

Objective To observe the effects of ferulic acid on cell apoptosis andβ-tubulinin vitro of rabbit sinoatrial node injured by hypoxia and low glucose, and to explore its mechanism.Methods Model cells were established on sinoatrial node cells from newborn rabbit by performing deprivation of oxygen and glucose. Then the model cells were divided into 5 groups: a normal control group, a model group, ferulic acid high, medium and low dose group. The normal control group and the model group were treated with equal volume of culture medium, and the three volume ferulic acid groups were treated with ferulic acid of 100, 20, and 10μg/ml respectively. Flow cytometry, laser scanning confocal microscopy were used to observe the sinoatrial node apoptosis rate and cytoskeleton proteinβ-tubulin in each group.Results Apoptosis rate of the model group was obviously higher than the normal group (56.95% ± 11.99%vs. 31.45% ± 6.32%,P<0.01), whileβ-tubulin cleavage was significantly lower than the normal group (5.141 ± 0.218vs. 8.035 ± 0.762,P<0.01). Apoptosis rate of ferulic acid high, medium dose group were significantly lower than the model group (24.85% ± 6.34%, 26.70% ± 9.84%vs. 56.95% ± 11.99%,P<0.01),β-tubulin structure were significantly more complete compared with the model group (7.927 ± 0.357, 5.961 ± 0.351vs. 5.141 ± 0.218,P<0.01).Conclusions Ferulic acid can suppress apoptosis of sinoatrial node cells caused by low glucose and oxygen. Protecting the sinoatrial node cell skeleton protein ofβ-tubulin may be one of the mechanisms.
