Objective To investigate the accuracy of analgesia/nociception index (ANI) in assessing the severity of postoperative pain in patients.Methods Eighty patients,aged 21-77 yr,of American Society of Anesthesiologists physical status Ⅰ-Ⅲ,scheduled for elective operation,were admitted to the postanesthesia care unit after the patients were extubated at the end of operation,and ANI was monitored.Immediately after admission to the postanesthesia care unit (T0),numerical rating scale (NRS) score was recorded.If NRS score was 0-3,the patients received no treatment,and NRS score was recorded again 10 min later (T1).If NRS score was 4-10,fentanyl 50 μg was injected intravenously,and NRS score was recorded again 5 min later (T2).ANI value was recorded at T0,T1 and T2.NRS score was considered as the criterion for assessment of the severity of pain.The receiver operating characteristic curve was used to analyze the sensitivity and specificity of ANI in determining NRS scores,the cut-off value was determined,and the area under the curve and 95％ confidence interval were calculated.Pearson correlation was used to analyze the correlation between ANI and NRS score.Results The area under the curve (95％ confidence interval) of ANI in determining NRS scores was 0.873 (0.816-0.929),and the cut-off value was 45 with a sensitivity of 74.8％ and a specificity of 87.5％.ANI was negatively correlated with NRS score,and the correlation coefficient was-0.705 (P＜0.05).Conclusion ANI provides high accuracy in assessing the severity of postoperative pain with a cut-off value of 45 in the patients.

Objective To investigate the effect of cyclosporine A(CsA)on viral protein syn- thesis and hepatitis B virus(HBV)DNA replication in vitro.Methods The HBV DNA transfected cell line HepG2.2.15 was treated with different concentration of CsA(0.6-20.0?g/ml)for 4 days. Hepatitis B surface antigen(HBsAg)and hepatitis B e antigen(HBeAg)in supernatant were detected by enzyme-linked immunosorbentassay(ELISA);intracellular hepatitis B core antigen(HBcAg)mR- NA and HBV DNA were analyzed by RT-PCR and slot blot hybridization,respectively;the phospho- rylation at tyrosine acid position 402 of PyK2 kinase(PyK2 Y402)was detected by Western blot.Re- sults CsA could suppress the expression of HBsAg and HBeAg,and inhibit the HBV DNA replica- tion in a dose-dependent manner.The suppression rate of HBsAg and HBeAg under the action of CsA at the concentration of 10.0?g/ml for 4 days was 49.7% and 34.3%,respective;similar effect was observed on HBV DNA replication,HBV DNA was only 34.9% of the control at the concentration of 10.0?g/ml of CsA.The phosphorylation level of PyK2 Y402 was declined under the action of CsA at the concentration of 2.0?g/ml.Conclusions CsA can inhibit the expression of HBsAg,HBeAg and HBV DNA replication in the HepG2.2.15 cell line in a dose-dependent manner.Suppression of the phosphorylation level of PyK2 Y402 maybe involved in the mechanism of the inhibitory activity of CsA on HBV replication.

Background Research showed that transforming growth factor-β2 (TGF-β2) promotes scar formation.But its mechanism in scarring after glaucoma filtration surgery is worthy of studying.Objective This study was to investigate the effect of TGF-β2 on myofibroblast transition of human Tenon fibroblasts (HTFs) and scarring after glaucoma filtration surgery.Methods Tenon capsular tissue was obtained from 3 patients with strabismus during the surgery and was incubated in DMEM with 10％ fetal bovine serum (FBS).The cells were collected and passaged in the free-serum medium for 24 hours,and then 1,2,5,10,20 μg/L TGF-β2 was added into the medium respectively,to induce the transformation of HTFs,and 2 μg/L or 5 μg/L TGF-β2 was used to treat the HTFs for 6,24,48 and 72 hours.The control group was not treated with TGF-β2.The expressions of α-smooth muscle actin (α-SMA) and phosphorylation of the signaling proteins (pSmad2) in HTFs were detected by Western blot assay.The expressions of α-SMA and F-actin were located by cell immunofluorescine technique under the confocal immunofluorescence microscopy.Cell contractility was determined by collagen gel contraction assays.This study was approved by Ethic Committee of Institute of Surgery Research of Daping Hospital,and informed consent was obtained from each patient or custodian initial of the study.Results The expression of α-SMA protein in the HTFs was increased significantly after the treatment of TGF-β2 in comparison with the control group and reached a peak at 24-48 hours.The α-SMA expression was gradually weakened in the 10 μg/L TGF-β2 groups.Little of α-SMA and F-actin were expressed in the control group.However,strong staining for α-SMA and F-actin were observed in the 1,2 and 5 μg/L TGF-β2 groups and then the staining weakened at the concentration of 10 μg/L.In addition,pSmad2 showed a stronger expression in the 2 μg/L TGF-β2 group than that in the PBS group and FBS group,with the strongest expression in 30 minutes through 2 hours.The untreated gel contracted (78.00±3.13)％ from its initial size,and contraction in the 1,2,5,10 μg/L TGF-β2 group were (63.88±1.78)％,(20.69±0.65)％,(19.49-±0.54)％,(16.24±0.84) ％,respectively,TGF-β2 increased HTFs contraction significantly (Fgroup =859.400,P =0.000).Conclusions TGF-β2 can induce transdifferentiation of Tenon fibroblast into myofibroblast and increase cell contractility,with a concentration-dependent and time-dependent pattern to an extent.It may be the mechanism of scar formation after glaucoma filter surgery.

OBJECTIVETo investigate the clinical value of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation (EPAS) in the treatment of premature ejaculation (PE).

METHODSTotally 69 PE patients were equally assigned to receive oral Paroxetine 20 mg/d, mid-frequency EPAS, or oral Paroxetine 10 mg/d combined with mid-frequency EPAS (P + EPAS) , all for 8 weeks. We obtained the intravaginal ejaculation latency time (IELT) and Chinese Index of Premature Ejaculation (CIPE-5) scores of the patients before and after treatment, and compared adverse reactions among the three groups of patients.

RESULTSOne patient of the Paroxetine group gave up treatment because of abdominal pain and nausea. Compared with the baseline, the patients in the Paroxetine, EPAS, and P + EPAS groups all showed markedly increased IELT ([0.92 ± 0.11] vs [4.07 ± 0.11] min, P < 0.01; [0.92 ± 0.12] VS [2.78 ± 0.17] min P < 0.05; [0.91 ± 0.09] vs [5.31 ± 0.13], P < 0.01) and decreased CIPE-5 scores (12.5 ± 3.0 vs 22.0 ± 2.1, P < 0.01; 12.8 ± 2.9 vs 19.5 ± 1.9, P > 0.05; 13.1 ± 2.8 vs 25.2 ± 2.1, P 0.01), with statistically significant differences between the P + EPAS group and the other two (P < 0.05). The total effectiveness rate was 95.7% in the P + EPAS group, remarkably higher than in the Paroxetine (72.7%, P < 0.05) and the EPAS group (47.8, P < 0.01).

CONCLUSIONOral Paroxetine combined with mid-frequency EPAS has a higher safety and efficacy than either Paroxetine or EPAS alone in the treatment of PE.

OBJECTIVETo discuss the protective effect of Mailuoning injection on ischemia/reperfusion (I/R) injury in rats and its mechanism.

METHODHealthy male adult Sprague-Dawley (SD) rats were randomly divided into the sham operation group, the model group, the edaravone (3 mg x kg(-1)) control group, and Mailuoning high, middle and low-dose groups (4, 2, 1 mL x kg(-1)), with 10 rats in each group, and administered with drugs through tail intravenous injection. The middle cerebral artery occlusion (MCAO) was adopted to establish the rat ischemia/reperfusion model. After the ischemia for 2 h and reperfusion for 24 h, the pathological changes in neurovascular units (NVU) of brain tissues at the ischemia side was observed by HE staining. The expressions of glialfibrillary acidic protein (GFAP) and ionized calcium-binding adaptor molecule 1 (Ibal) were detected by the immunohistochemical method. The expressions of tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) were detected by the western blotting technique.

RESULTMailuoning injection could significantly improve the pathological changes in cortical penumbra brain tissue UVN of (I/R) rats, reduce the number of GFAP and Ibal positive cells, and significantly decrease the expressions of TNF-alpha, IL-1beta, VCAM-1 and ICAM-1 of brain tissues of I/R rats.

CONCLUSIONMailuoning injection shows an obvious protective effect on UVN of I/R rats. Its mechanism may involve the inhibition of the activation of astrocyte and microglia and the secretion and expression of various inflammatory factors.

Objective To observe the therapeutic effects of the co-administration of γ-aminobutyric acid (CABA), sodium dimercaptopropane sulfonate (Na-DMPS) and vitamin B6 in large doses on liver and heart of rats with acute tetramine intoxication, and compare their separate effects of either GABA or Na-DMPS alone with those of the triad combination. Method Thirty rats were randomized into control group (n = 6), tetramine intoxication without treatment group (n = 6), tetramine intoxication treated with GABA group (n = 6), tetramine intoxication treated with Na-DMPS group (n = 6) and tetramine intoxication treated with triad combination (GABA + Na-DMPS + vitamin B6, GNDV n = 6) group. Samples of blood, liver tissue and heart tissue of rats with acute tetramine intoxication were collected immediately two hours after medication with different drugs. Serum alanine aminotrasferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) were measured, and the pathological changes of liver tissue and heart tissue were observed under microscope. Results The symptoms of poisoning were apparently relieved and the latency for convulsion/muscular twitch were obviously delayed in poisoned rats treated with GABA, Na-DMPS and GNDV separately. Furthermore, combination group showed the latent period delayed longer than either GABA or Na-DMPS groups The GABA, Na-DMPS and GNDV significantly lowered the serum levels of ALT, AST, CK and CK-MB in rats with tetramine intoxication, and those serum levels of enzymes were lower in GNDV group than those in either GABA group or Na-DMPS group. However, there were no difference in those serum enzymes between GABA group and Na-DMPS group. Moreover, the intoxicated rats treated with combination treatment had the slightest pathological changes in liver and heart (GNDV < GABA or Na-DMPS). Conclusions The co-administration of γ-aminobutyric acid, sodium demercaptopropane sulfonate and vitamin B6 in large doses for the treatment of tetramine intoxication is a method of choice.

Objective To observe the reactivity of pupillary diameter variation responding to numerical rating scale on postoperative pain to explore the accuracy of pupillary diameter variation for pain assessment.Methods Eighty patients after selected surgery (male 43 cases,female 37 cases,aged 24-79 years,ASA gradeⅠorⅡ)were included for the trial.After endotracheal extubation and on arri-val in the post-anaesthesia care unit (PACU),the levels of pain on numerical rating scale (NRS)were rated and recorded subsequently.If NRS was within 0-3,no analgesic was administered and 50 μg fentanyl was administrated after 5 min if NRS rated in 4-10.The pupillary diameter (PD),systolic blood pressure (SBP)and heart rate (HR)were recorded every minute during 20 minute after first NRS evaluation,the corresponding maximum variation of above index were calculated simultaneously in 10 minutes with NRS 0-3,after 5 minutes with NRS 0-3 to 4-10,after 5 minutes with NRS 4-10 to 0-3,in 10 minutes with NRS 4-10 which were marked respectively with ΔPD,ΔSBP and ΔHR.With the variation of NRS as a criterion,the reactivity of ΔHR,ΔSBP and ΔPD responding to NRS varia-tion were assessed by analysing the receiver operating characteristic curve (ROC),the area under the receiver operating characteristic curve (AUC)was calculated.Results The patients' ROC value ofΔHR,ΔSBP and ΔPD responding to NRS variation were AUCΔPD 0.904 (95% CI 0.822-0.987 ), AUCΔSBP 0.65 1(95%CI 0.5 10-0.781)and AUCΔHR 0.588(95%CI 0.444-0.733)respectively.Value of AUCΔPD was larger than that of AUCΔSBP and AUCΔHR respectively (P < 0.05 ).Importantly, operating characteristic curve (ROC)analysis showed that the diagnostic cutoff value of ΔPD was 41.3% with a sensitivity of 80.0% and a specificity of 93.5% and the diagnostic cutoff value of ΔSBP was 10.3% with a sensitivity of 62.4% and a specificity of 71.5%.Conclusion This study demon-strated that the accuracy of ΔPD was higher than ΔSBP and ΔHR responding to pain/analgesia evalu-ation.ΔPD was a valuable index for assessment of postoperative pain.
