Objective To determine the optimal cut-off value of critical-care pain observation tool (CPOT) in assessing degree of pain in patients undergone craniotomy, and to determine the sensitivity and specificity of CPOT with this cut-off value. Methods A prospective observational study was conducted in Beijing Tiantan Hospital. A total of 118 patients admitted to intensive care unit (ICU) after craniotomy was consecutively enrolled during August 2014 to August 2015. CPOT and visual analogue scale (VAS) were used to assess the pain before, during and 20 minutes after the removal of central venous catheters, and the difference was compared between two scores at three time points. Receiver operating characteristic (ROC) curve was used to determine the optimal cut-off values for evaluation of the sensitivity and specificity of CPOT. Patients' complaint of pain was considered the gold-standard. Results CPOT values (inter-quartile range) before, during and after the procedure were 0 (0-3), 0 (0-6) and 0 (0-2), respectively; while VAS values were 4 (1, 6), 3 (1, 6) and 4 (1, 6), respectively. CPOT value during the procedure was significantly higher than CPOT values before and after the procedure (both P < 0.01). When the optimal cut-off value of CPOT was 1, CPOT showed the highest Youden index before, during and after the procedure (1.183, 1.515, and 1.438, respectively), and showed high specificity (all 100%) and low sensitivity (18.3% and 43.8%, respectively) when assessing the pain before and after the removal of the catheter. The sensitivity and the specificity were high when assessing the pain during the procedure, the sensitivity was 69.4%, and the specificity was 82.1%. When the optimal cut-off value of VAS was 2 before and during the procedure, and was 4 after the procedure, VAS showed the highest Youden index, 1.568, 1.452, and 1.509, respectively. VAS demonstrated high sensitivity and specificity before, during and after the procedure (sensitivity was 97.2%, 95.2% and 75.0%, respectively; specificity was 59.6%, 50.0% and 75.9%, respectively). The area under ROC curve (AUC) of CPOT before, during and after the procedure were 0.592 [95% confidence interval (95%CI) = 0.490-0.693], 0.778 (95%CI= 0.693-0.863) and 0.719 (95%CI = 0.627-0.811), respectively; the AUC of VAS before, during and after the procedure were 0.846 (95%CI = 0.771-0.920), 0.767 (95%CI = 0.681-0.854) and 0.838 (95%CI = 0.767-0.909), respectively. The AUC of VAS before and after the procedure was significantly higher than the AUC of CPOT (P < 0.001 and P = 0.006), while there was no significant difference between the AUC of VAS and CPOT during the procedure (P = 0.826). Conclusion CPOT can be used to assess the pain during painful procedure, and it shows high accuracy, but with poor evaluation effect on pain in rest.

To study the influence of the compatibility of ophiopogonis tuber and Chinese magnoliavine fruit with gastrodia rhizome on the pharmacokinetics of gastrodin in rat, three dosages of compound Tianma granule extract (equivalent to gastrodin 50, 100, 200 mg x kg(-1)) and one dosage of Tianma extract (equivalent to gastrodin 100 mg x kg(-1) were administered to rats by intragastric administration separately. Plasma samples were collected at different times and treated with methanol and acetonitrile to precipitate protein. The contents of gastrodin in plasma were determined by HPLC method. The mean plasma concentration-time curves of different medication administration teams were processed with WinNonlin 5.2.1 pharmacokinetic software. The pharmacokinetic parameters of different medication administration teams were analyzed with SPSS statistics 17.0 software. The results indicated that the in vivo kinetic process of gastrodin was fitted to first-order absorption un-compartment model at low, middle dosages and zero-order absorption un-compartment model at high dosage of compound Tianma granule extract. By comparison with the pharmacokinetic parameters of gastrodin (100 mg x kg(-1)) in Tianma extract, the significant decrease for Cmax and significant increase for MRT0-infinity in compound Tianma granule extract indicated that the compatibility of ophiopogonis tuber and Chinese magnoliavine fruit with Gastrodia rhizome can delay the absorption, reduce the elimination rate and prolong the action time of gastrodin in vivo.

Aim To investigate the role of chemokine-like factor 1 ( CKLF1 ) in SH-SY5 Y cell migration and its molecular regulatory mechanism. Methods SH-SY5Y cells were stimulated with CKLF1 for 0. 5 h, 2 h, 8 h and 24 h, respectively. The migration distance and the percentage of migration cells were recorded by CELLocate analysis. The phosphorylation of focal ad-hesion kinase ( FAK) at Tyr-397 site was detected by Western blot analysis. By chemotaxis assays, we con-firmed the chemotaxis of CKLF1. Furthermore, FAK inhibitor PF-573228 and PLCγ inhibitor U73122 were used for the research of molecular regulatory mecha-nisms involved. Results CKLF1 promoted cell migra-tion and induced a strong increase in the phosphoryla-tion level of FAK-pY397 , which were significantly at-tenuated by the presence of U73122 ( a specific inhibi-tor for PLCγ) . In addition, the chemotaxis of CKLF1 was obviously blocked by the FAK inhibitor PF-573228 . Conclusion CKLF1 induces SH-SY5 Y cell migration via PLCγ/FAK signaling pathway.

Objective To evaluate the efficacy of 0.1% tacrolimus ointment and 0.1% mometasone furoate cream in the treatment of chronic actinic dermatitis (CAD). Methods Forty male patients with CAD were recruited and divided into two groups randomly.Twenty cases were treated with 0.1%tacrolimus ointment (Group A), and the other 20 cases were treated with 0.1% mometasone furoate cream (Group B) . The medications mentioned were applied topically to the lesions on the face twice a day and mizolastine tablet 10 mg per day given orally for 4 weeks. The therapeutic efficacy and side effects of medications were observed. The enzyme linked immunosorbent assay (ELISA) method was used to measure the serum levels of IFN-γ, IL-2 and IL12 in CAD patients before and after treatment with topical tacrolimus ointment and mometasone furoate cream. Results (1) Both groups had overall response rates of 100%, with no statistically significant difference ( > 0.05) . (2) Serum levels of IFN-γ,IL-2 and IL-12 were down-regulated after treatment in both treatment groups respectively ( < 0.01) . No statistically significant difference was found between the two treatment groups ( > 0.05) . Conclusion 0.1%tacrolimus ointment is effective in the treatment of CAD. Its therapeutic efficacy is equivalent to that of 0.1%mometasone furoate cream. It can be used as a possible steroid sparing equivalent.

Objective To explore the establishment methods of animal models of adult growth hormone deficiency, and to provide a good model for experimental research and treatment for abnormal bone metabolism caused by growth hor-mone deficiency.Methods The methods of establishment of animal models of adult growth hormone deficiency were re-viewed and evaluated refering to literature.Results There were three methods including spontaneous lack-of, pituitecto-mized and gene knockout can establish animal models of adult growth hormone deficiency.Conclusions Hypophysecto-mized animal models are inexpensive and easy to create, but not suitable for studying the relationship between growth hor-mone and bone metabolism.Spontaneous lack-of and gene knockout models are specific growth hormone deficiency and of great research significance in exploring the relationship between growth hormone and bone metabolism.

Objective To analyze the clinical and pathological factors that affect the prognosis of gastric cancer patients after radical resection,and study the relationship between biological behavior of gastric cancer and clinical so as to provide clues to the basis for clinical diagnosis and treatment.Methods The clinical and pathological data of the gastric cancer patients who underwent radical resection from January 1999 to December 2009 were retrospectively analyzed.Of the 581 eligible patients were followed up in 179 cases.A database was established for SPSS 13.0 software analysis.Results Single factor analysis showed that the prognosis influencing factors in gastric cancer patients after radical resection were age,tumor location,tumor size,gross type,histological type,depth of invasion,TNM stage,surgical procedure,the cancerous remains of specimen surgical margin and the number of lymph node metastasis (P ＜ 0.05 or ＜ 0.01),no correlation was found between gender and prognosis (P ＞ 0.05).Multiple Cox regression analysis showed that TNM stage and number of lymph node metastasis were independent gastric cancer prognostic influencing factors,and the number of lymph node metastasis was found to be the more significant factor.Conclusions TNM stage and the number of lymph node metastasis are independent prognostic influencing factors in gastric cancer,and the number of lymph node metastasis is the more important factor in gastric cancer prognosis.Therefore,Union for International Cancer Control lymph node staging of gastric cancer is a better indicator for gastric cancer prognosis.
