Objective To observe the effect of midazolam plus propofol administered for colonoscopy on cognitive function in middle-aged and aged patients. Methods One hundred and thirty six patients, ASA I and II, aged 40~75 years and undergoing colonoscopy were randomized to propofol group (group P, n=68) and propofol plus midazolam group (group PM, n=68). Baseline cognitive function was measured using Mini mental state exami-nation (MMSE) before anesthesia and the cognitive testing was repeated 10 minutes after emerging from anesthesia. BP, HR, SpO2, analgesic effect and sedative drug doses in both groups were recorded. Procedure time, recovery time and Rasmay sedation score were both recorded. Results Recovery time was significantly longer in group PM than that in group P (P<0.05). The total dose of propofol was significantly smaller in group PM than that in group P (P<0.05). MMSE score of both groups decreased, but the incidence of cognitive decline and the level of cognition in group PM were more notable than those of group P (P<0.05). Conclusions Midazolam plus propofol and propo-fol alone administered for colonoscopy could both increase the incidence of cognitive decline, and the effect of the former is more notable, but midazolam added to propofol could reduce the dosage of propofol.

Objective To evaluate the clinical efficacy of transcatheter super-selective hepatic artery embolization (TAE) in treating symptomatic polycystic liver disease (PLD). Methods A total of 8 patients with PLD, who were admitted to authors’ hospital during the period from 2009 to 2013 to receive TAE, were enrolled in this study. The patients included 6 females and 2 males with a mean age of 59.5 years (54-65 years). The used embolic agents were polyvinyl alcohol (PVA) microspheres and micro spring coils. Both plain and contrast-enhanced CT scans of the upper abdomen were performed before TAE as well as at 12 months after TAE; the total volume of the hepatic cysts was measured and the changes of the cystic volume were determined. Statistical analysis was conducted using paired t test. Results The technical success rate was 100%. After TAE, the patients developed fever and different degrees of discomfort at liver area, which were disappeared after active symptomatic medication, and no serious complications occurred. The patients were followed up for 12 months , the mean total volume of the intrahepatic cysts decreased from preoperative (5 794±2 066) cm3 (range 3 120-8 935 cm3) to postoperative (3 832±1 525) cm3 (range 2 019-5 925 cm3), the difference was statistically significant (t=6.971, P<0.001). The reduction ratio of total volume of intrahepatic cysts was 34.6%±11.3%(24.3%-60.4%). Conclusion For symptomatic polycystic liver disease, transcatheter super-selective hepatic arterial embolization is a newly-developed treatment. This technique is safe and effective with reliable response and fewer complications. Therefore, it should be recommended in clinical practice.

Objective To evaluate the efficacy of anesthesia with different doses of dexmedetomidine combined with propofol and remifentanil in patients undergoing abdominal surgery.Methods Ninety ASA Ⅰ or Ⅱ patients of both sexes,aged 18-64 yr,weighing 45-80 kg,undergoing abdominal surgery,were randomly assigned into 3 groups ( n =30 each):control group (group C ),dexmedetomidine 0.25 μg· kg-1 · h-1 group ( group D1 ) and dexmedetomidine 0.50 μg· kg-1·h-1 group (group D2 ).Dexmedetomidine was infused at a rate of 0.25 μg·kg-1 ·h-1 and 0.50 μg·kg-1 ·h-1 in groups D1 and D2 respectively until extubation after a loading dose of 0.5 μg/kg over 15 min.In group C,normal saline was infused intravenously at a rate of 10 ml/h.Anesthesia was induced with TCI of propofol with the target plasma concentration (Cp) of 1.0 μg/ml,iv injection of cisatracurium 0.2 mg/kg and TCI of remifentanil with Cp of 3 ng/ml.The patients were tracheal intubated and mechanically ventilated.PETCO2 was maintained 35-40 mm Hg and SpO2 was maintained ≥95％.Anesthesia was maintained with TCI of remifentanil with the target Cp of 5 ng/ml,iv infusion of cisatracurium 0.1 mg· kg-1 · h-1 and TCI of propofol.The target Cp of propofol was increased to maintain Narcotrend index of 37-46.The amount of remifentanil,cisatracurium and propofol consumed,extubation time and eye-opening time,complications during operation and during recovery from anesthesia were recorded.Results There was no significant difference in the amount of remifentanil and cisatracurium consumed and extubation time among the three groups ( P ＞ 0.05).Compared with group C,the eye-opening time was significantly prolonged,the incidence of hypertension and tachycardia during operation,and restlessness,vomitting,hypertension,and tachycardia during recovery from anesthesia was significantly decreased in groups D1 and D2,and the amount of propofol consumed was significantly decreased in group D2 (P ＜ 0.05).Compared with group D1,the eye-opening time was significantly prolonged,the incidence of hypertension during operation,and restlessness,hypertension,and tachycardia during recovery from anesthesia was significantly decreased in group D2 ( P ＜ 0.05).Conclusion When combined with propofol and remifentanil,dexmedetomidine infused at a rate of 0.50 μg·kg-1 · h-1 can provide satisfactory efficacy for abdominal surgery.

Objective To explore the difficulty and strategy of percutaneous transheptic stenting for the junction of malignant hepatic duct obstruction. Method Twenty-three patients with highly malignant biliary obstruction received percutaneous transheptic biliary drainage (PTBD) by placement of stent and/or internal-external drainage tube. All the 23 patientws were followed up to determine the successful rate of surgery, the incidence of complications, decreased serum level of bilirubin, patency time of biliary stent and survival time. Results The initial operation was sucessful in 22 cases, accounting for 95.65%. Twenty-one patients had significant decline in total bilirubin (60%) and 2 had not (10%). The levels of alanine aminotransferase (GPT) and aspartate aminotransferase (GOT) decreased markedly and returned to nomral in an average of 18 d. After operation, 2 patients had fever,1 biliary tract bleeding, 6 pain in the right upper abodminal region, 1 localized peritonitis around the puncture point, 3 GPT increase and 1 drainage tube slip. There were no serious complications such as hemorrhea and biliary fistula etc. The symptoms of all these complications disappeared in 2 to 5 days through haemostasis, anti-inflammatory therapy and liver function protection. The median survival time was 8.5 months. Conclusion Although the merging of malignant hepatic duct obstruction stenting is difficult, try to pass through the obstruction by guide wire and master the right methods of operation can significantly improve the successful rate of surgery.

A RP-HPLC method was established for simultaneous determination of phellodendrine hydrochloride (PH1), magnoflorine hydrochloride (MH), jatrorrhizine hydrochloride (JH), palmatine hydrochloride (PH2) and berberine hydrochloride (BH) in Phellodendri Chinensis Cortex by using ionic liquids as mobile phase additives. The separation was performed on a Kromasil C18 (4.6 mm x 250 mm, 5 μm) coupled with ultraviolet (UV) detection. The effect of extraction solvent, detection wavelength, length of alkyl chain on different imidazolium ionic liquids and concentration of ionic liquids on the separation and determination of alkaloids were investigated. Ionic liquid, [BMIm] BF4, can obviously improve the resolution and peak shape. This ILs-HPLC method is simple, rapid, and reliable, which can be used for determination of alkaloids in Phellodenddri Chinensis Cortex.

The DNA structures could be altered or even damaged by exogeous or endogenous factors during cell proliferation. Failure of effective and timely repair will lead to cell cycle arrest or apoptosis. By taking the advantage of the quick proliferation of cancer cells, DNA damage induction, cell cycle arrest and apoptosis promotion have become important strategies for ant-cancer chemotherapy. Previous reports showed that an array of natural compounds inhibit cancer cell proliferation by inducing DNA damage, which have therapeutic potentials for anti-cancer drug research and development.
