Objective To investigate influence of dexmedetomidine on postoperative cognitive function in elder patients after hip re-placement surgery under spinal anesthesia. Methods Forty elderly patients with ASAⅠ~Ⅲ,undergoing hip replacement with spinal anesth-sia,were randomly divided into dexmedetomidine group( group A) and normal saline group( group B) ,with 20 patients in each group. Dexme-detomidine was given with 1 μg/kg after anesthesia and followed with 0. 5 μg·kg-1 ·h-1 in group A. The equal volume of normal saline was infused in group B. Cognitive function was evaluated before anesthesia,3 and 7 days after surgery by mini-mental state examination( MMSE) . The intraoperative concentration of TNF-α,IL-6,MDA were detected at the time of before surgery(T0),end of surgery(T1),3 days after sur-gery(T2),7 days after suegery. Results There was no significant difference in MMSE score before anesthesia between the two groups (P>0. 05). The difference of MMSE score at postoperative 3 days between two groups was statistical significance (P<0. 05). The MMSE score recovered normal in both groups 7 days later. There was no significant difference of TNF-α,IL-6,MDA concentration at T0 between two groups(P>0. 05). Compared with T0,the concentration of TNF-α,IL-6,MDA at T1,T2 in group B increased,the difference was significant. And the concentration of IL-6 at T1 in group A decreased,compared with that at T0,the difference was significant(P<0. 05). The concentra-tion of TNF-α,IL-6 at T1,T2 and MDA at T2 in group A were lower than those in group B,the difference was significant. (P<0. 05). Con-clusion Dexmedetomidine can decreased the concentration of TNF-α,IL-6,MDA,and improve the postoperative cognitive dysfunction of eld-erly patients who finished the hip replacement surgery under spinal anesthesia.

OBJECTIVETo investigate the effect of triptolide (TPL) on the renal tissue of diabetic rats and its possible mechanisms.

METHODSSD rats were randomly divided into the normal control group (as the normal group), the diabetic model group (the model group), the low dose TPL treatment group (the low dose TPL group, TPL 0.2 mg/kg by gastrogavage), the high dose TPL treatment group (the high dose TPL group, TPL 0.4 mg/kg by gastrogavage). Equal volume of normal saline was given to rats in the normal group and the model group. Five rats were randomly selected from each group at week 4, 8, and 12 of the experiment to detect body weight, kidney weight, 24 h urinary albumin (24 h UAL), plasma glucose (FBG), total cholesterol (TC), total triglyeride (TG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), white blood cell (WBC), and hemoglobin A1c (HbA1c). The mRNA and protein expression of regulated upon activation normal T-cell expressed and secreted (RANTES) in the renal tissue was assessed by reverse transcription-polymerase chain reaction (RT-PCR) and enzyme linked immunosorbent assay (ELISA). The renal tissue was pathologically stained by HE, PAS, and Masson staining. The glomerular and renal tubular interstitial lesions were observed at each time point. The glomerular sclerosis index (GSI) was observed by PAS staining, and the renal interstitial filrosis index (RIFI) was calcutated.

RESULTSCompared with the same group at week 4, the expression of 24 h UAL, RANTES, GSI, and RIFI at week 12 significantly decreased in two TPL groups (P <0.01). Compared with the same group at week 8, the expression of 24 h UAL, RANTES, GSI, and RIFI at week 12 also significantly decreased in the two TPL groups (P <0. 05, P <0.01). Compared with the normal group, body weight and the kidney weight obviously decreased at week 4, 8, and 12 in the model group (P <0. 01); 24 h UAL, FBG, TG, TC, HbA1c, RANTES, GSI, and RIFI were obviously elevated (P <0.01). Compared with the model group, 24 h UAL, RANTES, GSI, and RIFI also decreased in the two TPL treatment groups (P <0.01). Compared with the low dose TPL group, they were attenuated in the high dose TPL group (P <0. 05, P <0. 01).

CONCLUSIONTPL could not only inhibit the over-expression of RANTES, but also improve the glomerular sclerosis and renal interstitial fibrosis in the renal tissue of diabetic rats.

Cinobufacino injection is a significant anti-tumor medicine for the treatment of various tumors in clinic, which was made from water extraction of the skin of Bufo bufo gargarizans. In present paper, HPLC-DAD-FT-ICR-MS method was used to identify the major bufadienolides in cinobufacino for the first time. Solid-phase extraction with dichloromethane and silica was used to enrich the total bufadienolides in cinobufacino. Based on the UV and high resolution MS/MS data, 33 bufadienolides were analyzed and characterized. Among them, eight compounds were identified by comparing with standard references unambiguously. This study elucidated the major bufadienolides in cinobufacino, which provided material foundation of cinobufacino and will be benefit for the further pharmacological research.

To obtain chemical constituent information of rat plasma after oral administration of Huang-Lian-Jie-Du Decoction (HLJDD), a LC-FT-ICR-MS method has been established, and both positive and negative ions scan modes were include in the analysis. By comparing their retention time, high resolution mass data of HLJDD extracts, blank plasma and dosed plasma, 38 constituents, including 22 prototype compounds and 16 metabolites, were detected in rat plasma after oral administration of HLJDD. In the 22 prototype compounds, 16 constituents were determined unambiguously by comparing with references. In the analysis of metabolites, phase II reactions like glucuronidation and sulfation were the major biotransformation pathways of HLJDD. M11 was observed as the only phase I metabolite in present experiment. The results will be beneficial for the further pharmacokinetics and pharmacological evaluations of HLJDD.

To establish the local quality standard for Dendrobii devoniani caulis from Longling, Yunnan, the pharmacognostic characteristics microscopic characteristics and TLC identification were developed. Sulfuric acid-phenol method was used to determine the content of polysaccharide. An HPLC method was adopted to determine the content of mannose, and extractives were determined according to the procedures recorded in the Appendix of Chinese Pharmacopoeia(2010). The results showed a strong characteristics microscopic of Dendrobii devoniani caulis, and its TLC identification had a good resolution with clear spots; the content of polysaccharide is 35.7% -52.1% (average 42.7%), mannose 27.8%-46.1% (average 35.8%), and extract 4.5%-10.6% (average 7.38%). The method is simple, accurate and reliable, with good reproducibility. The established standard is acceptable for quality evaluation of Dendrobii devoniani caulis from Longling, Yunnan.

This research is to establish an HPLC method for the simultaneous determination of ophiopogonin D, ophiopogonin D', ophiopogonin C, deacetylophiopojaponin A and ophiogenin-3-O-α-L-rhamnosyl-(1-->2)-β-D-glucoside in Ophiopogonis Radix. HPLC-ELSD analysis was performed on a Kromasil 100-5 C₁₈ column (4.6 mm x 250 mm, 5 µm), with the mobile phase of acetonitrile (A) -water (B) in gradient elution mode (0-45 min, 35%-55% A), at a flow rate of 1 mL · min⁻¹. The column temperature was 35 °C and the drift tube temperature was 100 °C in a gas flow rate of 3.0 L · min⁻¹. The result showed that baseline of all the 5 constituents was well separated, and every constituent had wide linearity range and good linear relation (r > 0.999). The recovery rate was between 95.75% and 103.1%. The new established method for simultaneous determination of saponin constituents in Ophiopogonis Radix was sensitive and has good, repeatability. It could be applied to quality evaluation of Ophiopogonis Radix.
