Background and purpose:Hypoxia induced the decreased radiosensitivity of tumor cells, which was the cause of tumor radioresistance and relapse and metastasis. During the course, HIF-1a played the most important role in the regulation of hypoxia. However, it’s still unknown about the effect of HIF-1a on the radiosensitivity of hypoxia tumor cells and the relationship with autophagy. This study was to inhibit HIF-1αexpression in hypoxic lung adenocarcinoma cell line A549 with RNA interference (RNAi), and explore its effect on hypoxic cell radiosensitivity and autophagy. Methods: Plasmids pHIF-1α-shRNA and Neg-shRNA (negative control) were constructed and transfected into hypoxic A549 cells, this positive clone was named A549/HIF-1α-shRNA. Clone formation array was applied to calculate the value of D0, SF2, SER. The expression of HIF-1α, LC3, c-parp was detected by Western blot. Results:The SF2 of hypoxic A549 cell was 0.62, which was higher than that of normoxic A549 cell, SER was 1.45. The level of LC3Ⅱincreased significantly and the level of c-parp decreased after the radiation of hypoxic A549 cell. The level of HIF-1a increased in hypoxic A549 cells. The expression of HIF-1αin hypoxic A549 cells was suppressed markedly after transfection of HIF-1α-shRNA;this clone was named A549/HIF-1α-shRNA. The SF2 and SER were significantly lower in A549/HIF-1α-shRNA cells, 0.45 and 0.72 respectively. Under the hypoxic condition and after the inhibition of HIF-1α, the expression of LC3Ⅱ decreased significantly and the expression of c-parp increased. Conclusion:We successfully established a cell model that HIF-1αexpression was suppressed almost completely by RNAi. The inhibition of HIF-1αby shRNA may raise the radiosensitivity and decrease the autophagy of hypoxic A549 cells in vitro.

Objective To evaluate the impact of epidural anesthesia with levobupivacaine combined with general anesthesia on colon surgery. Methods Sixty patients undergoing elective radical procedure for colon carcinoma were randomLy divided into four groups: saline group (group S), 0.125% levobupivacaine group (group L1), 0.25% levobupivacaine group (group L2), and 0.5% levobupivacaine group (group L3). Group S received normal saline of 10 mL epidurally and then infusion of 5 mL·h-1 until the procedure was finished; groups L1, L2, and L3 received levobupivacaine instead. Anesthetic induction was performed after epidural puncture. Mean blood pressure and heart rate were recorded at 8 time points including 5 min after entering into the operation room, 1 min after intubation, skin incision, abdominal exploration, 1 h after skin incision, completion of operation, extubation, and leaving PACU; meanwhile blood glucose and cortisol were detected, anesthesia time, time to PACU stay, bleeding, transfusion volume, adverse reaction, and doses of propofol, remifentanil, ephedrine, and fentanyl were noted. Results Time to PACU stay was longer in S group than in other 3 groups. Doses of remifentanil and fentanyl were larger in L1 group than in L2 group and L3 group. Ephedrine dose in L3 group was larger than in other 3 groups. Blood sugar in L1 group was higher than L2 group and L3 group. Cortisol in S group was higher than in other 3 group. Cortisol in L1 group was higher than in L3 group. The number of patients with hypotension was greater in L3 group than other 3 groups. Conclusions Continue epidural infusion of 0.25%levobupivacaine can reduce stress response and opioid uses, shorten PACU stay, whereas it does not increase use of ephedrine.

Objective To study the rational daily administration times of Yinchenhao Decoction (YCHD) when it was used to treat experimental jaundice in rats based on pharmacodynamics/pharmacokinetics model.MethodsRats were modeled by 4% 1-naphthylisothiocyanate (75 mg/kg) for 48 h,then YCHD was drenched with doses of 0.324 g/kg (extract,calculated with the clinical dosage) once,0.162 g/kg twice,and 0.108 g/kg thrice a day,respectively.The total bile and the flow rate of bile were observed after the first administration; Blood samples collected from the orbital sinus at different intervals were used to investigate the levels of liver enzymes (ALT and AST) and bilimbins (TBIL and DBIL),and determine the concentration of 6,7-dimethoxycoumarin (DME) in the plasma using UPLC at the same time,then we obtained the time-effect and time-dose curves.The rational daily administration times of YCHD when treating experimental jaundice were determined based on the comprehensive analysis of time-effect and time-concentration relationships.ResultsWithin 10 h the total bile of rats which were administered once daily (G1) was I.65 and 1.33 times higher than that of twice and thrice (G2 and G3) a day,respectively,and the four biochemical indexes (TBIL,ALT,DBIL,and AST) of Gl decreased faster than those of G2 and G3 (P < 0.05).On the other hand,the blood drug level of DME when administrated once daily could maintain at a higher level for a longer time,and its Cmax and AUC0→t were higher than those of G2 and G3,which might be the main reason why its effect was the most significant.ConclusionIt is more appropriate to administrate once daily when YCHD is used to treat jaundice.
