Objective To evaluate the role of sonic hedgehog (SHH) signaling pathway in spinal neurons in morphine tolerance (MT) in mice.Methods Pathogen-free healthy female Kunming mice,weighing 20-25 g,aged 8-10 weeks,were used in the study.MT was induced with morphine 10 mg/kg injected subcutaneously twice a day for 7 consecutive days.The experiment was performed in two parts.Experiment Ⅰ Forty-eight mice were randomly assigned into 2 groups:control group (group C,n =8) and MT group (group M,n=40).The thermal pain threshold (TPT) was measured at 1 day before morphine injection and 1,3,5,7 and 14 days after the end of injection.Eight mice in each group were sacrificed at 2 h after measurement of TPT at each time point after the end of injection in group M or at 2 h after the last measurement of TPT in group C,and the lumbar segment (L4-6) of the spinal cord was removed.Experiment Ⅱ Forty-eight mice were randomly assigned into 6 groups (n=8 each):SHH inhibitor cyclopamine plus MT group (group CP+M),cyclopamine solvent plus MT group (group D1 +M),SHH agonist SAG plus MT group (group SAG+M),SAG solvent plus MT group (group D2+M),MT plus cyclopamine group (group M+CP) and morphine plus cyelopamine solvent group (group M+D1).At 15 min before morphine injection,cyclopamine 10 mg/kg was injected subcutaneously in group CP+M,and SAG 5 mg/kg was injected subcutaneously in group SAG+M.Cyclopamine 10 mg/kg was injected subcutaneously once a day during the 1-3 days after the end of morphine injection in group M+CP.The TPT was measured before injection of morphine,at 30 min after the first injection of morphine every day and at 1-3 days after the end of morphine injection.The animals were sacrificed at 2 h after the last measurement of TPT,and the lumbar segment (L4-6) of the spinal cord was removed for determination of the expression of SHH signaling pathway-related proteins SHH,ptch1,smo,gli1 and gli3 using Western blot.Results Experiment Ⅰ Compared with group C,the TPT was significantly decreased at 1 and 3 days after the end of morphine injection (P＜0.05),no significant change was found in TPT at 5-14 days after the end of morphine injection (P＞0.05),and the expression of SHH,smo and glil at 1-5 days after the end of morphine injection,of ptchl at 1 and 3 days after the end of morphine injection and of gli3 at 7 days after the end of morphine injection was up-regulated in group M (P＜0.05).Experiment Ⅱ Compared with group D1+M,the TPT was significantly increased,the expression of SHH,ptchl,smo and glil was down-regulated,and gli3 expression was up-regulated in group C P+M (P＜0.05).Compared with group D2+M,the TPT was significantly decreased,the expression of SHH,ptch1,smo and glil was up-regulated,and gli3 expression was down-regulated in group SAG+M (P＜0.05).There was no significant difference in the parameters mentioned above between group M+CP and group M+D1 (P＞0.05).The TPT was significantly lower on 3rd-7th days after beginning of morphine injection and 1-3 days after the end of morphine injection than at 30 min after the first injection of morphine in group CP+M (P＜0.05).Conclusion The mechanism underlying the development of MT is partially related to activation of SHH signaling pathway in spinal neurons of mice,however,the maintenance mechanism has no marked relationship with it.

OBJECTIVE To establish an in vitro blood-cerebrospinal fluid barrier (BCB) model to investigate the underlying mechanism of lead-induced BCB injuries.METHODS The in vitro BCB model was established by Z310 cells.Different concentrations of Pb(AC)2 (2.5,5.0 and 10.0 mmol·L-1) were used for 24,48 and 72 h.Transendothelial electrical resistance (TEER) and flux of FITC-dextran were performed to determine the permeability of the in vitro BCB model.Western blotting and immunofluorescence methods were used to observe the expression of tight junction protein ZO-1 and occludin.RESULTS Compared with control group,Pb(AC)2 2.5,5.0 and 10.0 mmol· L-1 exposure for 48 h to Z310 cells had no significant effect on survival rate and density.TEER in different groups was gradually increasing.At the 12th day after Pb(AC)2 exposure,the values of TEER and flux of FITC-dextran in Pb(AC)2 5 and 10 mmol· L-1 groups were significantly decreased (P＜0.05).Western blotting and immunofluorescence images showed that the expression of ZO-1 and occludin were significantly decreased (P＜0.05) after Pb(AC)2 exposure for 48 h.CONCLUSION Lead exposure can cause the breakdown of BCB barriers,and this effect may be mediated by reducing the expression of ZO-1 and occludin proteins.

Objective To explore the effect of MECT on learning memory in depressed rats and its synaptic plasticity mechanism. Methods Fifty SD rats were randomly divided into 5 groups( n =10): MECT (received ECT with intraperitoneal propofol), ECT (received ECT only), propofol (received intraperitoneal propofol), depression, and control. The treatments were given daily for 7 consecutive days. All rats underwent open field and Morris water maze test. The SYP protein and mRNA expressions in rat hippocampus were detected using immunochemistry and RT-PCR, respectively. Results After treatment, the open field scores were much higher in MECT and ECT groups than in propofol and depression groups ( P <0.05); the learning memory was worse in ECT group than in MECT, propofol and depression groups ( P <0.05); the expressions of SYP protein and mRNA was higher in MECT and ECT groups than in propofol and depression groups ( P <0.05), the expressions of SYP protein and mRNA were lower in MECT group than ECT group ( P <0.05). Conclusions Propofol can improve learning memory in ECT-treated depressed rats through attenuation of ECT-induced expression of SYP in rat hippocampus.

Objective To investigate the syndrome type distribution of hypertensive patients; To analyze the correlation of characteristics of HRV time domain parameters and its influence factors. Methods Totally 515 cases of hypertensive patients were included and were put under syndrome type distribution. Demographic information, laboratory test parameters, risk factors and clinical symptoms were collected for correlation analysis. HRV time domain parameters were recorded by using 24 h ambulatory electrocardiogram. The differences in SDNN, SDNN Index, HRV Index, PNN50, and RMSSD of different TCM syndrome types were compared. Results Among 515 patients: 160 cases with hyperactivity of yang due to yin deficiency syndrome, 136 cases with turbid phlegm and blood stasis syndrome, 83 cases with overabundant liver-fire syndrome, 69 cases with deficiency of kidney qi, and 67 cases with abundant phlegm-dampness syndrome. By comparing different TCM syndromes, the level of SDNN was significantly reduced in the hyperactivity of yang due to yin deficiency syndrome, overabundant liver-fire syndrome,deficiency of kidney qi syndrome compared with turbid phlegm and blood stasis syndrome, abundant phlegm-dampness syndrome (P<0.05); SDNN Index and HRV Index decreased significantly in the hyperactivity of yang due to yin deficiency and overabundant liver-fire syndrome compared with abundant phlegm-dampness syndrome (P<0.05). SDNN Index decreased significantly in the deficiency of kidney qi compared with abundant phlegm-dampness syndrome (P<0.05). The level of PNN50 was significantly reduced in the deficiency of kidney qi compared with hyperactivity of yang due to yin deficiency syndrome (P<0.05). RMSSD decreased significantly in the hyperactivity of yang due to yin deficiency syndrome, deficiency of kindney qi syndrome, overabundant liver-fire syndrome compared with turbid phlegm and blood stasis syndrome (P<0.05). Discriminant analysis showed that SBP, DBP, MBPS, SDNN, SDNN Index, HRV Index, PNN50, RMSSD were correlated with the diagnosis of five syndrome types. Logistic regression analysis showed that the factors including gender (female), insomnia, elevated systolic blood pressure, MBPS, decreased SDNN Index and PNN50 were positively correlated to hyperactivity of yang due to yin deficiency; other factors including gender (female), advanced age, elevated blood pressure, decreased SDNN, HRV Index and RMSSD were positively correlated with turbid phlegm and blood stasis syndrome. And the study also showed that advanced age, family history of hypertension, elevated blood pressure, decreased SDNN Index, HRV Index and PNN50 were positively correlated to abundant phlegm-dampness syndrome. Conclusion HRV time domain parameters can be significantly reduced in the hyperactivity of yang due to yin deficiency, overabundant liver-fire syndrome, and deficiency of kidney qi syndrome. The autonomic nerve function is damaged seriously. Hyperactivity of yang due to yin deficiency syndrome, abundant phlegm-dampness syndrome turbid phlegm and blood stasis syndrome are closely related to the influencing factors that lead to cardiovascular and cerebrovascular events.

Objective To investigate the effects of different doses of propofol on expression of synaptophysin (SYP) mRNA and protein in the hippocampus of mentally depressed rats after electroconvulsive therapy (ECT) .Methods Fifty adult male SD rats weighing 200-250 g were randomly divided into 5 groups (n = 10 each): group Ⅰ control (group C); group D mental depression (group D) ; group Ⅲ , Ⅳ , Ⅴ propofol 90, 110, 130 mg/kg + ECT (group M_1, M_2, M_3). Mental depression was induced by isolation and chronic unpredictable mild stress (CUMS) in group Ⅱ-Ⅴ . Group M_1 , M_2 and M_3 received intraperitoneal (IP) propofol 90, 110 and 130 mg/kg respectively + ECT once a day ×7 consecutive days while group C and D received IP normal saline instead of propofol. The rats underwent open field test and sucrose liquid consumption test the day before and after mental depression was established and one day after treatment. The rats were killed after the last test for determination of expression of SYP mRNA (by RT-PCR) and protein (by immuno-histochemistry) in the hippocampus. Results The ambulation scores, rearing scores, grooming time and sucrose consumption percentage were significantly decreased while the center,grid detention time (CDT) was significantly increased in group Ⅱ-Ⅴ as compared with control group indicating mental depression was successfully induced. The ambulation scores, rearing scores, grooming time, sucrose consumption percentage, SYP mRNA and protein expression were significantly increased while CDT was significantly decreased after treatment in group M_1 and M_2 as compared with group D indicating that propofol 90 or 110 mg/kg combined with ECT was effective for the treatment of mental depression.Conclusion Propofol 90 or 110 mg/kg combined with ECT is effective in treating mental depression while proprofol 130 mg/kg combined with ECT is not. Excessive inhibition of SYP expression in hippocampus by large dose of propofol may explain the mechanism.`

Objective To investigate risk factors and prognosis of hemorrhagic transformation(HT)in acute cerebral infarction patients treated by intravenous thrombolysis with recombinant tissue plasminogen activator(rt-PA).Methods All 128 patients with acute cerebral infarction were treated with intravenous rtPA within 6 hours from stroke onset.The clinic records and laboratory datas of pre-and post-treatment were statistically analyzed between HT group and non-HT group to find potential risk factors to HT and contributors of prognosis.Results HT occurred in 29 patients(22.66％),including 16 patients with symptomatic ICH(12.50％)and 2 patients died(6.90％ of HT).Logistic regression analysis showed that history of atrial fibrillation(OR =1.293,95％ CI 1.224-1.589,P =0.001),CT density changes with mass effect or edema(OR =2.452,95％ CI 1.132-3.309,P =0.034),diastolic blood pressure ≥ 100 mm Hg before thrombolytic therapy(1 mm Hg =0.133 kPa,OR =9.265,95％ CI 1.435-59.836,P =0.019),blood glucose ≥ 11.1 mmol/L(OR =3.037,95％ CI 0.252-57.593,P =0.047),NIHSS score ＞ 15 points (OR =8.752,95％ CI 1.035-30.285,P =0.023)and thrombolysis time ＞ 3 h(OR =98.74,95％ CI 5.067-186.120,P =0.002)are independent risk factors for HT; among these factors,baseline blood glucose(OR =3.265,95 ％ CI 0.435-59.863,P =0.045),NIHSS score(OR =10.453,95 ％ CI 5.647-38.185,P =0.003)and thrombolysis time(OR =2.541,95％ CI 1.098-51.086,P =0.017)also are prediction factors of the prognosis of HT.Conclusion Risk factors associated with HT are diastolic blood pressure before thrombolysis,glucose level,degree of neurological deficits,CT early changes,atrial fibrillation and thrombolytic time.Glucose level,neurological deficits and thrombolysis time affects the prognosis of patients.
