Objective:To study the mechanism of anti-proliferative effect of lupeol on highly metastatic human hepatocellular car-cinoma HCCLM3 cells. Methods:CCK-8 assay was performed to evaluate the effects of lupeol at different concentration on cell viability in 12-48 h. Caspase inhibitors were used to identify the subtypes of caspases activated during lupeol-induced cell death. The effects of lupeol on the mRNA expression of caspase family and Bcl-2 related genes were detected by real-time PCR. The effects of lupeol on HC-CLM3 cell phase distribution were investigated by flow cytometry. Results:Compared with the control group, lupeol could inhibit HC-CLM3 cell proliferation in a concentration-dependent manner with IC50 of 93 μmol·L-1 in 24h. The number of HCCLM3 cells in the period of G2/M was increased by 1-fold when the lupeol concentration was within 60-100 μmol·L-1 . Lupeol could activate the path-way of caspase, and the mRNA expression of caspase-3 was elevated by 50%-150% when compared with that in the control group. Mo-reover, the mRNA expression of p53 and Bax were increased above 1-fold by lupeol at 100 μmol·L-1 , and the Bcl-2 and PARP ex-pression were significantly suppressed by lupeol at 60-100 μmol·L-1(P<0. 05 or P<0. 01). Conclusion:The results indicate that lupeol has anti-proliferative effect on the liver cancer cells, which is beneficial to the prevention and treatment of liver cancer.

Objective To summarize the characteristics of nosocomial infections in the patients treated in intensive care unit (ICU).Methods The incidence of nosocomial infections was monitored in ICU from March 2012 to August 2012.The incidence rate of infection was adjusted with Average Severity of Illness Score (ASIS)score and analyzed in relation to three invasive pro-cedures.Pathogen distribution of nosocomial infections in ICU was also analyzed.Results Nosocomial infection was identified in 357 of the 3 700 ICU patients (9.65%).The overall daily infection rate was 30.34‰,specifically,49.10‰ for ventilator asso-ciated pneumonia (VAP),13.86‰ for catheter-related bloodstream infections (CRBSI),and 1.09‰ for catheter-associated urinary tract infections (CAUTI).Of the 688 bacterial isolates,gram negative bacteria accounted for 82.70%.The top three bacterial species were Acinetobacter baumanii ,Pseudomonas aeruginosa ,and Klebsiella pneumoniae .Conclusions ICU is the focus for surveillance of nosocomial infections.Objective investigation is critical for nosocomial infection surveillance.

The diagnostic value of glutamic acid decarboxylase antibody (GAD 65-Ab) was more valuable than islet cell antibody (ICA) in type 1 diabetes mellitus by receiver-operating characteristic (ROC) curves; likelihood ratios of different regions of GAD 65-Ab and ICA could reflect the probability of type 1 diabetes mellitus.

Objective To observe the effect of scalp nerve block ( SNB ) with ropivacaine hydrochloride at different time points on pain management after craniotomy. Methods Ninety patients undergoing craniotomy were randomly divided into 3 groups:group A, SNB conducted before surgery;group B, SNB conducted after surgery;group C, SNB conducted both before and after surgery, with 0. 5% of ropivacaine hydrochloride in each group. All patients received the same general anesthesia and diclofenac sodium were administered rectally as rescue analgesics. Sites and duration of surgeries, end-tidal sevoflurane concentration during incision, HR and SBP levels during the course of surgery and postoperative period, the VAS scores, GCS and Ramsay scores at 0. 5, 2, 4, 6, 12, 24, 48 h postoperatively, time of the first rescue appication analgesics and total consumption of rescue analgesics, the adverse effects, awareness under anesthesia were analyzed respectively, as well as local anesthesia relevant adverse events and time of wound healing. Results The end-tidal sevoflurane concentration was significantly decreased in group B (3. 19±0. 36)% as compared with group A (1. 81±0. 24)% and C (1. 77±0. 33)% (P<0. 05);The VAS scores of group A (3. 77±2. 27, 4. 20±2. 09) at 2 and 4 h were higher than those in group B (2. 77±1. 98, 3. 20±2. 20) and C (2. 97±1. 77,2. 27±1. 93) (P<0. 05), while at other time points the differences were not significant (P>0. 05);Compared with group A (600 mg), the consumption of rescue analgesics of group B (300 mg) and C (250 mg) were statistically lower (P<0. 05);Vital signs, GCS, Ramsay scores, time of the first rescue analgesics postoperatively used, and time of wound healing among the three groups were not various significantly (P>0. 05);The relevant side effects were not different statistically, and there were no patients suffering from obvious awareness under anesthesia, pruritus, respiratory depression or local anesthesia relevant adverse effects. Conclusion SNB conducted before surgery can decrease the consumption of sevoflurane during incision, but has limited analgesic effects postoperatively. SNB conducted after surgery may provide transitional analgesia for neurosurgical patients undergoing craniotomy, while SNB conducted both before and after surgery does not show significantly longer analgesic time in postoperative pain management.
