To observe the effects of Danshen-containing serum on SuFu and DYRK2 expression in the HSCs stimulated by leptin. SD rats (n = 60) were used to make danshen-containing serum by gastric perfusion for ten days with Danshen water decoction, normal saline and colchicine. The HSCs that were cultured in vitro would be stimulated for 24 hours by leptin (100 μg x L(-1)) except blank control group, after being intervened, the drug serum in each group would be cultured at 37 degrees C in 5% incubator. The cells would be collected after 24 hours, then the effects of danshen-containing serum on the proliferation of HSCs were detected by MTT, the expression of SuFu mRNA and DYRK2 mRNA were detected by RT-PCR, the expression of SuFu and DYRK2 proteins were tested by Western blot. Compared with blank control group, the expression of DYRK2 mRNA and DYRK2 proteins were enhanced obviously after stimulated the HSCs of rats by leptin (P < 0.01), but the expression of SuFu mRNA and SuFu proteins were decreased significantly (P < 0.01). Compared with the model group, after cyclopamine group (Hh pathway inhibitor), Danshen-containing serum and colchicine were interfered, the expression of DYRK2 mRNA and DYRK2 proteins were decreased clearly (P < 0.01), but the expression of SuFu mRNA and SuFu proteins were increased significantly (P < 0.01 or P < 0.05). Compared with model group, adding purmorphamine (Hh pathway agonist) to model group and making it activate could increase the expression of DYRK2 mRNA and DYRK2 proteins, but the expression of SuFu mRNA and SuFu proteins were decreased significantly (P < 0.01). Compared with the model group, using the Danshen-containing serum to interfere the purmorphamine group could make the expression of DYRK2 mRNA and DYRK2 proteins decrease and the expression of SuFu mRNA and SuFu proteins increase significantly (P < 0.01). Danshen-containing serum would inhibition the activation and increment of HSCs by interfering the expression of SuFu and DYRK2 which were induced by leptin.

OBJECTIVETo evaluate in vivo pharmacokinetics of Ophiopogonis Radix polysaccharide MDG-1 oily suspension injection prepared with different prescriptions in rats, and explore the feasibility of the long-acting drug delivery of MDG-1 Injection by using the oily suspension drug release system.

METHODMDG-1 microparticles were prepared by the anti-solvent precipitation method. Their size and size distribution were characterized. Castor oil with a high viscosity or aluminum stearate were added into soybean oil with a low viscosity, in order to prepare oily media with different viscosities, detect their rheological properties and screen out superior prescriptions for in vivo evaluation.

RESULTThe average size of microparticles was 21.81 microm, and the span between them was 2.63. The in vivo evaluation was conducted for prescriptions of mixed oil (soybean oil/castor oil, 2: 3) and soybean oils gelled by 2% and 4% aluminium stearate. Among them, the prescription of soybean gelled by 4% aluminium stearate could significantly reduce C(max) and prolong the apparent t1/2, with the MDG-1 release time of several days.

CONCLUSIONIt is feasible to achieve the long-acting MDG-1 drug delivery by using oily media with a high viscosity.

Objective To observe the efficacy ,safety and patient acceptance of the artificial airway with the oro‐pharyngo‐laryn‐gead airway cap(OPLAC) for hip replacement surgery in patients with intravenous‐inhalation combined anesthesia .Methods Sev‐enty eight cases of patients receiving the hip replacement surgery were included ,42 patients were to be adopted to establish artificial airway with the OPLAC for intravenous‐inhalation combined anesthesia ,another 36 patients treated with heath side‐lying position hypobaric spinal‐epidural anesthesia .There are two groups ,the oro‐pharyngo‐laryngead airway cap group(OPLAC ,n=42) and hy‐pobaric combined spinal‐epidural anesthesia group (CESA ,n=36) .Monitor the changes of respiratory and circulatory parameters of the two groups before the start of anesthesia ,anesthetic after 10 min ,30 min ,1 h ,and handling marrow ,observing occurrence of complications (delirium ,sore throat ,nausea ,vomiting ,deep vein thrombosis) ,following up the degree of satisfaction of patients and surgeons for anesthesia .Results The respiratory and circulatory parameters of the OPLAC group during anesthesia induction and maintenance were relatively stable ,on the other hand ,significant cyclic inhibition (blood pressure and heart rate decresing ) and re‐spiratory rate declining were observed in the CESA group after anesthesia ,cases with the use of atropine and dopamine significantly more than OPLAC group .The circulation and breath in the OPLAC group were relatively stable when handling marrow ,while cir‐culation fluctuating Significantly in the CESA group (blood pressure decreasing and heart rate increasing ) .The incidence of delirium in the CESA group was significantly higher than OPLAC group .The patient satisfaction of the OPLAC group was significantly bet‐ter than the CESA group .Conclusion The artificial airway with OPLAC for hip replacement surgery in patients with intravenous‐inhalation combined anesthesia is safe ,effective ,and satisfactory .

HPS1-D, an active polysaccharide,was isolated and purified from Hedysarum polybotrys. HPS1-D was obtained after treated with Savage method and H2O2, and purified with DEAE-cellulose 52 and Sephadex G-100 gel filtration chromatography. Then physicochemical property analysis, GC, methylation, partial acid hydrolysis, and NMR method were used to study chemical structural of HPS1-D. The conformation was primarily analyzed with GPC-MALLS method and Congo red reaction. The anti-complementary activity of HPS1-D was evaluated with the hemolysis assay. HPS1-D was a heteropolysaccharide and consisted of D-glucose, L-arabinose, (7.2:1.3). HPS1-D proved to be a neutral sugar, with 1, 4-and 1, 4, 6-alpha-D-glucopyranosyl residues in backbone ,and 1, 5-and 1, 3, 5-alpha-L-arabinofuranosyl residues in branches. HPS1-D has a random coil state conformation with monodisperse mass distribution in 0.9% NaCl solution. And HPS1-D had triple-helix conformation in concentrate of NaOH solution. Anti-complementary activity of HPS1-D was closed to its positive control heparin.

Advanced gastric cancer is usually dealt with D2 radical dissection. There are different opinions as to whether it is necessary to perform D3 radical lymphadenectomy.Some scholars thought that properly enlarged radical dissection can improve long-term outcomes for the treatment of advanced gastric cancer.In recent years,laparoscopic D1 and D2 radical dissection of gastric cancer could be carried out in many hospitals.However,the technique and related skills for performing D3 radical lymphadeneetomy through laparoscope remains to be explored.Based on our previous experiences,D3 radical lymphadeneetomy using artery suspension method and medial-to-lateral approach for advanced gastric cancer is proved to be safe and feasihle.

Objective To observe the changes of inflammatory factors and clinical parameters on septic patients with hemoperfusion,and to discuss the application of hemoperfusion on sepsis. Methods 43 patients with sepsis were divided into treatment group and control group randomly. In the treatment group,the patients received conventional treatment and hemoperfusion together,which performed every 24 hours,continuously for 3 times when they arrived in ICU in the first hour. The concentrations of TNF-α,IL-6,IL-10 and PAF were dynamically detected before hemoperfusion,after 24 hours,48 hours and 72 hours in treatment group. The concentrations of TNF-α,IL-6,IL-10 and PAF were compared between the two groups after 72 hours. So did the clinical parameters as WBC count,CRP,PCT and blood lactate acid. Results The concentrations of TNF-α,IL-6, IL-10 and PAF were increased significantly in the early stage of sepsis,and were decreased obviously after hemoperfusion(P < 0.01). After 72 hours treatment,the concentrations of TNF-α,IL-6 and PAF were decreased rapidly,so did the level of CRP,PCT and blood lactate acid. There were significant differences between the two groups(P < 0.05). ConclusionHemoperfusion could remove the inflammatory factor of septic patients and improve the clinical symptoms of them.
