AIM: To investigate the effect of taurine on calcification of vascular smooth muscle cells (VSMCs).METHODS: Calcified VSMCs of rat in vitro were induced by ?-glycerophosphate. Cellular calcium content,alkaline phosphatase(ALP) activities and accumulation were measured. DNA synthesis were evaluated by -thymidine (-TdR) incorporation. RESULTS: Calcium content,ALP activities and uptake of calcified VSMCs stimulated by taurine (5-20 mmol/L) were greatly decreased in a concentration-dependent manner as compared with calcified group ( P

Objective To evaluate the effects ofbeta-endorphin (β-EP) and substance P (SP)with sedative and analgesic drugs on mechanical ventilated patients. Methods Twenty-eight mechanical ventilated patients were randomly divided into two groups: midazolam group (M group, 14 cases) and midazolam combined with fentanyl group (M + F group, 14 cases). Eight healthy persons were as control group (C group). The sedative target was VAS≤3 scores and Ramsay 2-4 scores. The levels of serum β -EP and SP were tested before sedation and 12, 24 h after sedation in mechanical ventilated patients and at 8 Am in C group. The sedation levels were evaluated and the hemodynamie and respiratory parameters were recorded before sedation and 1, 12, 24 h after sedation in mechanical ventilated patients. The oxygenation index was measured before sedation and 1,12, 24 h after sedation. Results The levels of serum β -EP and SP in M and M+F group were significantly higher than those in C group(P< 0.05). After sedation, the level of SP in M+F group [(101.42 ± 12.46) ng/L]was significantly lower than that in M group [(132.72 ± 23.82) ng/L] (P < 0.05). Compared with before sedation, there were significant differences in heart rate, VAS and Ramsay scores between M group and M+F group (P< 0.05). Compared with M group, pressure airway and respiratory rate at 12, 24 h and total after sedation were lower in M+F group (P <0.05). The amount of serum SP in mechanical ventilated patients. Fentanyl improves the ventilator synehron and reduces the dose of midazolam.

Objective To investigate pathogens and drug resistance of lower respiratory tract infection(LRTI)in Intensive Care Unit(ICU).Methods Retrospective study of the clinical data,the distribution and the drug-sensitivity of pathogens of 220 cases with LRTI in ICU.Results Totally 280 strains of pathogens were identified by bacterial culturing.The ratio of G-bacteria to total pathogens isolated was 63.5%,of the G+ bacteria was 25.1%,and of the fungi was 11.4%.The main kinds of the G-bacteria were Klebsiella pneumoniae(17.1%),Pseudomonas aeruginosa(13.2%),Acinetobacter baumannii(12.5%),and Stenotrophomonas maltophilia(10.4%).Staphylococcus aureus(SA)(91.4%)was the most prominent in G+ bacteria,and MRSA was 98.4% in SA.The result of drug sensitive test in vitro showed the multiple drug fast rate of Pseudomonas aeruginosa was comparatively high,Stenotrophomonas maltophilia to Levofloxacin was low,Klebsiella pneumoniae and Acinetobacter baumannii were highly sensitive to carbapenems.The susceptibility rate of MRSA to vancomycin was 100%.Conclusion G-bacteria are the majority of the pathogens,isolated from patients with LRTI in ICU.Klebsiella pneumoniae,Pseudomonas aeruginosa,Acinetobacter baumannii,and Stenotrophomonas maltophilia are the chief G-pathogens.Except Stenotrophomonas maltophilia,imipenem and merpenem are relatively active against the G-bacilli.The proportion of MRSA and fungal infection is increasing.It is suggested that there be urgent need for surveillance of bacterial resistance and rational use of antimicrobial agents during clinical therapy.

Acute aortic syndrome(AAS) is a lethal disease with acute onset and a high mortality rate as well as a higher incidence rate especially in an aging population. The diagnostic techniques of AAS have been improving in recent years. Many serum biomarkers have been shown to have the potential of further clinical implication. Advancement of imaging techniques has also improved the accuracy of early diagnosis. Although traditional treatment modality involving open surgery is life-saving, it still has a high mortality rate and a high major morbidity rate. The increasing utilization of endovascular techniques has greatly improved the prognosis of AAS, while it still need further optimization to be applied in different subgroups of patients.

Objective To study the changes of volatile oil of Atractylodis Rhizoma(AR)and Atractylodis macrocephalae Rhizoma(AMR)before and after co-decocting in different proportions(1∶3,1∶2,1∶1,2∶1,3∶1).Methods The volatile oil was extracted by steam distillation and analyzed by gas chromatography-mass spectrometry(GC-MS).Results After co-decocting,the yield of volatile in each group was higher than in single decocting.The relative contents of most components in the mixed volatile oil after co-decocting were significantly different from the theoretical calculation.Co-decocting could promote the extraction of hinesol,which is the main component of the essential oil of AR,and the compatibility with large doses of AMR(1∶2 and 1∶3)could also promote the dissolution of β-eudesmol.At the same time,the extraction of atractylon,germacrene B and valencene was inhibited by co-decocting,which were the main constituents of the volatile oil of AMR.Conclusion Co-decocting of AR and AMR could improve the extraction rate and change the chemical composition of volatile oil.After co-decocting,the dissolution of active components of AR increased,while the dissolution of active components of AMR decreased.It may lead to the change of pharmacological activity.

Both immunosuppressants and antibiotics (ABX) are indispensable for transplant patients. However, the former increases the risk of new-onset diabetes, whereas the latter impacts intestinal microbiota (IM). It is still unclear whether and how the interaction between immunosuppressants and ABX alters the IM and thus leads to glucose metabolism disorders. This study examined the alterations of glucose and lipid metabolism and IM in mice exposed to tacrolimus (TAC) with or without ABX. We found that ABX further aggravated TAC-induced glucose tolerance and increased insulin secretion. Combined treatment resulted in exacerbated lipid accumulation in the liver. TAC-altered microbial community was further amplified by ABX administration, as characterized by reductions in phylum Firmicutes, family Lachnospiraceae, and genus Coprococcus. Analyses based on the metagenomic profiles revealed that ABX augmented the effect of TAC on microbial metabolic function mostly related to lipid metabolism. The altered components of gut microbiome and predicted microbial functional profiles showed significant correlation with hepatic lipid accumulation and glucose disorders. In conclusion, ABX aggravated the effect of TAC on the microbiome and its metabolic capacities, which might contribute to hepatic lipid accumulation and glucose disorders. These findings suggest that the ABX-altered microbiome can amplify the diabetogenic effect of TAC and could be a novel therapeutic target for patients.
