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.

Injections of propidium iedide (PI) into the lateral cerebral ventricle (LV) ofthe rat resulted in a prominent abnormality characterized by tremor,ataxia,andnystagmus.The intensity of PI fluorescence in the parenchyma of the brain fadedgradually away from the injection site and ventricles to the surfaces of the brain. In the forebrain it was seen that PI fluorescence reached the most lateral part ofthe ipsilateral caudate putamen nucleus.A constant neuronal labeling was observedin the septohippocampal nuclei,the A8-9-10 dopaminergic cell groups of themidbrain,the dorsal raphe nucleus,the median raphe nucleus,neurons within anddorsal to the medial lemniscus of the caudal midbrain,and Furkinje cells of thecerebellum.This neuronal labeling was bilateral.No distinct labeling was seen inother areas of the brain.Combined with Faglu histofluorescence,it was found thatalmost all of the dopaminergic neurons in the midbrain exhibited PI fluorescence.No labeled non-dopaminergic neuron was seen in A8-9-10.With a transection ofthe unilateral medial forebrain bundle,a prominent accumulation of PI fluorescencewas seen within the distal segments of catecholaminergic fibers near the transection,but no accumulation of PI was seen in the proximal segments.With LV injectionof Evans blue(EB)or DAPI or ethidium bromide,animals did not exhibit anyvisible abnormality.In animals with LV injection of EB or DAPI,although somelabeled cells were seen in the distant areas of the brain,their distribution wasdistinctly different from that of PI labeling.The above results indicate that besidesconfirming the LV injection of PI results in a prominent abnormality and PI isselectively uptaken by Purkinje cells,we have found that:a)PI is able to enter theparenchyma from the cerebrospinal fluid and diffuse widely in the brain;b)LVinjection of PI results in a selective labeling in certain specific areas of the brain,and those selectively labeled cells in A8-9-10 all are dopaminergic neurons;c)these dopaminergi(?) cells are labeled through axonal uptake and retrograde transportof PI.

The tanshinone ⅡA,an effective component of Radix Salviae Miltiorrhizae(RSM)can be extracted up to 90% in alcohol,but mostly decomposed in the later concentrating and drying procedures.Although reducing-pressure concentrating processes can reduce the decomposi- tion in experiment,but it can not preserve effectively the tanshinone during the large scale production because of the extended time of tanshinone in dampness and heat.Supercritical carbon dioxide extraction(SFE-CO_2)of RSM can give crystalline substance and dark red modifier when the alcohol is used as modifier at extraction pressure of 10 Mpa and the tem- perature at 40℃.The SFE-CO_2 technology can get higher concentration of tanshinone and be used during preparation production directly.The SFE-CO_2 technology is superior to the alco- hol-extraction technology.

One hundred and forty mice, weighing 30-35 grams, were divided into irradiation group (12 Gy total body irradiation from a 60Co source), combined radiation-burn group (12 Gy total body irradiation and 15% TBSA third degree burns), and normal control group.The dynamic changes of the intestinal epithelium were observed with light and electron microscopes and autoradiography within 96 hours after injuries, and attention was paid to the formation and conversion of the misshapen cells. It was Jound that the proliferative cycle of the young cells in the intestinal crypts which were severely injuried by irradiation was significantly retarded, and their G1-phase to G2-phase were prolonged. These cells gradually changed into misshapen cells. Some of the misshapen cells could not divide and finally they wer.e desquamated; abortive proliferation was found in some of them; some others showed pathological karyokinesis. Thus polymorphic cells were formed. It was difficult to show that the misshapen cells could take part in the repair of the intestinal epithelium. It is speculated that the misshapen cells might to some extent have the function of absorption, secretion and barrier.

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.

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.
