Aim To explore the modulation of Salvia miltiorrhiza on hyperpolarization-activated current (Ih) channels in dorsal root ganglion (DRG) neurons of rats and identify the mechanism of Salvia miltiorrhiza in alleviating pain and inhibiting calcium overload. Methods The effect of Salvia miltiorrhiza injection on Ih channels in DRG neurons of rats were examined by using whole-cell patch clamp technique. Results The experimental results showed that the amplitude of Ih evoked by -150 mV was (-1.06±0.18) nA. The Ih could be fitted well into the single kinetics and the time constant of activation, τ was clearly voltage-dependent with τ=(322.14±28.81) ms at -100 mV, decreasing to τ=(62.51±9.78) ms at -150 mV. The reversal potential of Ih was (-35.03±1.12) mV measured from tail currents. But no significant differences were found between the DRG neurons in the absence and presence of Salvia miltiorrhiza injection (10%, 25%, 50%) in the current amplitude, the time constant of activation and the reversal potential. The only difference between the DRG neurons in the absence and presence of Salvia miltiorrhiza injection was the half-activation potential of Ih. In control recordings the half-activation potential was (-106.07±3.59) mV. By comparison, the half-activation potentials changed to (-111.59±3.79) mV (n=31 neurons, P＜0.05), (-119.37±4.96) mV (n=31 neurons, P＜0.05) and (-121.23±3.86) mV (n=31 neurons, P＜0.05) in the presence of 10%, 25%, 50% Salvia miltiorrhiza injection, respectively. Conclusion Only the half-activation potential of Ih in the arthritic and neuropathic rat models shifted in the depolarizing direction, which increased the electrophysiological activity of Ih and made it related to peripheral hyperalgesia. The selective inhibition of Salvia miltiorrhiza on the electrophysiological activity of Ih may be one of the mechanisms underlying its analgesic effects.

Zebrafish is widely used as a model organism in the process of drug discovery. It expresses drug metabolizing enzymes like cytochrome P450 (CYP450), uridine 5'-diphospho-glucuronosyltransferase (UGT) and nuclear receptors like pregnane X receptor (PXR), aryl hydrocarbon receptor (AHR), etc. This article summarized the profiles of main drug metabolizing enzymes and nuclear receptors, and reviewed the advances on xenobiotics metabolism in zebrafish.

Objective Study on the best drug compatibility for the double-lumen endobronchial intubation anesthesia. Methods Eighty ASA Ⅰ - Ⅱ patients undergoing selective thoracis surgery requiring intubation with double-lumen tubes were randomly divided into A and B group, with 40 cases in each group.The systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), were recorded before induction (T0) , after drug injection (T1), during intubation (T2), and at 1 min (T3), 3 min (T4)and 5 min (T5) after intubation. Results There was no significant difference in SBP, DBP and HR between the two groups at T0[(124. 9 ± 16. 0) mmHg vs (125.8 ±6. 4) mmHg, (73. 1 ±9. 9)mmHg vs (74. 3± 10. 4) mmHg, (81.8 ± 6. 6) times/min vs (82. 4 ± 8. 1) times/min] (P ＞ 0. 05). Compared with parameter at T0, SBP, DBP and HR, parameters in two groups in T1 were all significantly decreased after anesthesia [(94. 8 ± 10. 03) mmHg vs (96. 9 ± 10. 1) mmHg, (57. 3 ± 7. 66) mmHg vs (55.4 ± 7. 03) mmHg,(69. 6 ± 7. 43) times/min vs (66. 3 ± 7. 03) times/min] (P ＜ 0. 05). The cardiovascular parameters at T0,T2, T3, T4 were all comparable with those in group B [SBP: (130 ± 11.6) mmHg, (125.6 ± 10. 43) mmHg,(120. 1 ± 12. 3)mmHg,(116. 8± 11.4)mmHg;DBP:(75.6 ±9. 12)mmHg,(76. 2 ±9. 8)mmHg,(73. 1 ±9. 2) mmHg, (71.6 ± 8.46) mmHg; HR: (88 ± 9. 12) times/min, (82. 9 ± 7.5) times/min, (81.9 ± 8.2)times/min, (79. 9 ± 7. 8) times/min] (P ＞ 0. 05) , which were significantly higher than those in group A [SBP: (146. 3 ± 14. 2) mmHg, (141.2 ± 10. 63) mmHg, (137. 2 ± 13.23) mmHg, (122. 9 ± 11.6) mmHg;DBP: (94. 9 ± 10. 6) mmHg, (84 ± 9.63) mmHg, (79. 9 ± 9) mmHg, (75.8 ± 8. 3) mmHg; HR: (102 ±10. 63) times/min, (97.6 ± 9. 23) times/min, (87. 7 ± 8. 2) times/min, (82. 1 ± 7.32) times/min] (P ＜0. 05). The parameters at T2, T3, T4 in group A were obviously higher than those group B (P ＜ 0. 05).Conclusions Cardiovascular response with double-lumen endobronchial intubation by sufentanil-induced was stronger than fentaty, sufentanil had more stable hemodynamic parameters and it worth to be usd in clinic.

Objective:To evaluate the relationship between single nucleotide polymorphism (SNP) +45T→G in adiponectin gene exon 2 and type 2 diabetes mellitus (T2DM), obesity and insulin resistance (IR) in Han population in Guangxi. Methods:Polymer-ase chain reaction-restriction fragment length polymorphism ( PCR-RFLP) was performed to identify the T-G polymorphism of adiponec-tin (exon 2) in 313 unrelated Han people from Guangxi including 95 normal glucose tolerance,103 impaired glucose tolerance and 115 type 2 diabetes mellitus. Results:In Han people of Guangxi, the SNP +45 GG genotype in adiponectin gene had significantly lower HDL-C levels than TT and TG genotypes in Han people(P<0. 05). The subjects with the GG genotype at position 45 had a signifi-cantly increased risk of IR (odds ratio of 2. 876[95%CI:1. 141-7. 248]) compared with those with the TT genotype at position 45. Conclusion:In Han people of Guangxi, the SNP +45 TT genotype in adiponectin gene has significantly higher HDL-C levels than GG genotype. The subjects with the GG genotype at position 45 have a significantly increased risk of IR compared with those with the TT genotype, while obesity and T2DM are independent on SNP+45 of adiponectin gene.

OBJECTIVE:To improve package inserts of chemical drugs so as to promote safe,rational and effective use of chemical drugs.METHODS:A total of 558 package inserts of different chemical drugs commonly used in the clinic were collected from our hospital and other local hospitals and analyzed statistically based on the regulations stipulated by the "Norms of Package inserts of Drugs(trial)".RESULTS:Some important items such as pharmaco-toxicology,usage and dosage,pharmacokinetics etc in the package inserts of chemical drugs failed to meet the state standards,but the package inserts of the imported chemical drugs superior to those of the domestic ones,those of the injections superior to those of oral preparations,and those of oral preparations superior to those of external preparations.CONCLUSION:The package inserts of chemical drugs are far from perfect,which thus remain to be improved further.

OBJECTIVE:To investigate the drugs that labeled with the warning remarks for pregnant and lactant women for reference of patients' rational drug use.METHODS:The package inserts of drugs commonly used in our hospital were investigated and the drugs with warming remarks for pregnant and lactant women were collected.RESULTS:A total of 186 package inserts were found to have warning remarks for pregnant and lactant women.CONCLUSION:Pharmacists should attach great importance to the rational use of drugs for pregnant and lactant women in drug dispending and tighten control on the prescriptions with contraindication in prescription check,and they should cooperate with clinicians in the rational use and choice of drugs based on package inserts.

Objective To investigate the clinical significance of the treatment of intrahepatic bile duct stones with fiber choledochoscope combined with intraoperative ultrasound.Methods The clinical data of 185 cases with intrahepatic bile duct stone were analysed retrospectively,included 96 cases with stone removal by fiber choledochoscope intra-and post-operatively(choledochoscope group),and 89 cases with stone removal by fiber choledochoscope combined with intraoperative ultrasound(combined group).Results The rateo of bile duct retained stones in choledochoscope group(9.38%) was higher than that in combined group(2.08%)(P=0.041),and the rate of bile duct recurrent stones in choledochoscope group(12.34%) was higher than that in combined group(3.61%)(P=0.036).There was no significant differences between the two groups in the occarrence of cholangitis(P=0.087),but 3 cases of severe cholangitis required re-operation in choledochoscope group.Conclusions Fiber choledochoscope combined with intraoperative ultrasound can decrease the rate of bile duct retained stones and bile duct recurrent stones,and can improve the therapeutic effect.
