Objective To explore the diagnostic value of the quantitative detection of serum miRNA-193a in pulmonary adenocarcinoma.Methods 40 pulmonary adenocarcinoma patients and 40 healthy people were recruited to receive quantitative detection of serum miRNA-193a and CEA.And then the relationship between the concentration of miRNA-193a and CEA was analyze by spearman correlation analysis.12 of the 40 patients underwent operation and the different levels of miRNA-193a expression among pulmonary adenocarcinoma tissues,adjacent tissues and normal tissues was detected by qRT-PCR.The different miRNA-193a levels were compared among groups of by t-test.The diagnostic performance of miRNA-193a was evaluated with receiver operating characteristic curves(ROC) and the area under the curve (AUC) and its 95%CI were calculated.Results The relative expressions of miRNA-193a in pulmonary adenocarcinoma tissues,adjacent tissues and normal tissues were 1.07±0.16;0.80±0.10;0.11±0.07.miRNA-193a expression in pulmonary adenocarcinoma tissues was significantly lower than that in other two groups(P<0.05).The expression of serum miRNA-193a in pulmonary adenocarcinoma group was significantly lower than that in healthy group(P<0.05).There was no correlation between miRNA-193a and CEA(r=0.079,P=0.618).The detection of miRNA-193a yielded a ROC AUC of 0.829(0.741-0.917) in discriminating pulmonary adenocarcinoma from healthy group.Conclusion The relative expression of miRNA-193a in pulmonary adenocarcinoma was significantly lower than that in healthy controls no matter in tissue or serum,serum miRNA-193a may prove to be a non-invasive biomarker for the auxiliary diagnosis of pulmonary adenocarcinoma.

OBJECTIVETo explore the feasibility and safety on lung resection surgery with the combined method of microinjection acupuncture (MIA) and intravenous anesthesia instead of compound traditional acupuncture and drug anesthesia (ADA).

METHODSNinety cases of lung resection surgery were randomized into a general anesthesia group, a MIA group and a ADA group, 30 cases in each one. In the general anesthesia group, before surgery, the intramuscular injection of atropine 0. 5 mg was used; during surgery, the anesthesia induction was followed with intravenous injection of fentanyl citrate, propofol and rocuronium bromide and the dosage was increased accordingly; after surgery, the analgesia pump was applied. In the MIA group, on the basis of general anesthesia, before anesthesia induction, the acupoint catgut embedding was applied to Jiaji (EX-B 2) of T4 , T6 and T, , Feishui (BL 13), Xinshu (BL 15) and Geshu (BL 17) on the affected side and bilateral Quchi (LI 11) and Zusanli (ST 36); after surgery, the analgesia pump was applied. In the ADA group, on the basis of general anesthesia, before! anesthesia induction, electroacupuncture (EA) was applied to Hegu (LI 4), Neiguan (PC 6) , Houxi (SI 3) and Zhigou (TE 6) for 30 min; during surgery, EA and intravenous medication were combined at the same acupoints as those before surgery; after surgery, moxibustion and the analgesia pump were applied in combination for analgesia. In each group, the biological indices were monitored during surgery at 11 time points named T. (before anesthesia I induction), T1 (intubation in general anesthesia induction), T2 (skin incision), T3 (rib exposure in muscular incision) T. (chest open), T, (lung removal), T6 (drainage tube implantation), T7 (chest closure), T (muscular stitching), T, (skin stitching) and T0 (extubation). The actual dosage of anesthetics during surgery and the, dosage of fentanyl citrate in analgesia pump were quantified after surgery. Results (1) In the MIA group and ADA group, the increased dosage of fentanyl citrate was less than that in the general anesthesia group [(1. 23±0. 28) µg . kg-1 . h-1 vs (2. 4±0. 54µg. kg-1 . h-1, (1. 1±0. 38µg . kg-1 . h-1 vs (2. 4±0. 54µg. kg-1 . h-1 , both P<0. 05]. The increased dosage of propofol and rocuronium bromide was not different during surgery among the groups (all P>0. 05). (2) In the MIA group and ADA group, after surgery, the increased dosage of fentanyl citrate was less than that in the general anesthesia group [(11. 0±1. 04)µg/kg vs (15. 4±1. 52µg/kg, (11. 5±1. 38µg/kg vs (15. 4±1. 52µg/kg, both P<0. 05], reducing by 25% in comparison. (3) The differences in heart rate and blood pressure at 11 time points during surgery were not significant among the three groups (all P>0. 05).

CONCLUSIONn The combined method of MIA and intravenous anesthesia significantly reduces the dosage of intravenous anesthetics during and after lung resection surgery as compared with ADA, presenting the similar analgesic effect as simple intravenous medication and the good safety. The combined method of MIA and intravenous anesthesia is much

Objective To investigate the role of NF-κB in apoptosis of immortalized neural progenitor cells (INPCs) . Methods INPCs were cultured in 6-well plates and were randomly divided into 5 groups ( n = 6 each) : group I was not transfected with any plasmid (group INPC); group Ⅱ was transfected with control plasmid (group INPC/CMV); group Ⅲ was transfected with plasmid RcCMV-p50 (group INPC/p50); group Ⅳ was transfected with plasmid RcCMV-p65 (group INPC/p65) and group V was transfected with plasmid RcCMV-p50 and RcCMV-p65 (group INPC/p50p65). Group INPC/CMV ( H ), INPC/p50 (Ⅲ) and INPC/p65 (Ⅳ) were screened by G418, and the positive clones were then cultured for 3-4 weeks. The transcription of p50 mRNA or p6S mRNA was detected by RT-PCR. The NF-κB activity was measured by luciferase reporter gene assay. The cell apoptosis was measured by annexin V/PI staining. In group INPC/p50p65 and group INPC/p65, the cultured positive clone was transiently transfected with plasmid RcCMV-p50. Two days after transfection, the same measurement was performed in group INPC/pS0p65 and the other groups. Results The expression of p50 mRNA was significantly increased in group INPC/p50 and INPC/p50p65 as compared with the other groups ( P < 0.05) . The expression of p65 mRNA, the NF-κB activity and the apoptotic rate were significantly increased in group INPC/p65 and INPC/p50p65 as compared with the other groups ( P < 0.05). Conclusion Enhanced NF-κB activity can increase immortalized neural progenitor cell apoptosis.

Objective: To observe the effect of preoperative effect on peri-operative pain in patients following a thoracotomy. Methods: 120 cases following lung-cancer thoracotomy were randomly allocated into four groups, 30 in each group. Cases in group A and B were treated with acupuncture analgesia 3 d before operation; cases in group A and C were treated with acupuncture analgesia after operation; and cases in group D were treated with general anesthesia. The pain management indexes in four groups were all controlled below 3. After that, analgesia-related β-endorphin and stress-related cortisol were observed before and after operation. In addition, the specific doses of postoperative analgesic-Fentanyl in four groups were compared. Results: The comparison of β-endorphin between group A, C and D showed P<0.05 one day before operation, so did group B, C and D 1 day before operation. The intra-group comparison of cortisol between the day of admission and 1 day after extubation and between 1 day before operation and one day after extubation in group A, B and D showed P<0.05, so did group C between the day of admission and 1 day after extubation. In addition, the contents of Fentanyl in postoperative analgesic pump in four groups showed P<0.05 through one-factor analysis of variance, showing a significant difference. Conclusion: Preemptive analgesia could increase the β-endorphin in patients following a thoracotomy and showed remarkable advantage when compared with the conventional postoperative analgesia. It did not cause significant difference regarding stress index cortisol. Acupuncture has no remarkable advantage when compared with operation and extubation for the major immediate stress. Additionally, postoperative acupuncture could be a substitute for the dose of pain killers and the match can be reduced by 20%.
