OBJECTIVETo reveal the quality variation of polysaccharides, triterpenoids and proteins in spores and fruiting bodies of Ganoderma lucidum from producing areas, different varieties, harvesting parts and periods, and wall-breaking treatments.
METHODSpores and fruiting bodies from varieties of Longzhi No. 1 and Hunong No. 1 were collected as test samples, together with wall-broken spores sold in domestic main producing areas. The anthrone-sulfuric acid colorimetric method was used to determine the content of total polysaccharides. The vanillin-glacial acetic acid-perchloric acid colorimetric method was used to determine the content of total triterpenoids. The Lowry method was used to determine the content of total proteins.
RESULTThe content ranges of total polysaccharides, total triterpenoids, and total proteins from 6 domestic main producing areas were 0.40% - 2.25%, 1.36%-3.15% and 0.74% -1.91% respectively. The content ranges of total polysaccharides, triterpenoids, and proteins in the fruiting bodies from 2 varieties cultured in Zhejiang were 0.25% -1.42%, 0.44% -1.42% and 1.82% -3.67% respectively. In addition, the ranges of samples from wall-unbroken spores were 0.41% - 0.91%, 0.09% - 0.12%, 0.78% - 0.90% respectively and wall-broken spores are 1.03% - 2.25%, 1.89% - 3.15%, 0.96% - 1.04% respectively.
CONCLUSIONThere are significant differences in the contents of main chemical ingredients of wall-broken G. lucidum spores saled in the markets. The samples from Zhejiang contain high content of total polysaccharides and triterpenoids, and samples from Fujian contains more proteins. Between the 2 major varieties cultured in Zhejiang, Longzhi No. 1 contains higher content of triterpenoids, but Hunong No. 1 has more polysaccharides. Contents of triterpenoids and polysaccharides from wall-broken spores are much higher than those of fruiting bodies. The stipes from fruiting bodies contains more polysaccharides than those of the pileus, while the triterpenoids contents are higher in the pileus than stipes. The pileus and stipes collected in the second year contain higher content of polysaccharides than the first year's samples, but the contents of triterpenoids are lower. Wall-breaking treatment would significantly improve the extraction and dissolution rate of total triterpenoids and polysaccharides.

Objective To observe the effect of potassium-rich diet on constipation for elderly patients with coronary heart disease (CHD) during hospitalization. Methods 100 elderly CHD patients were divided into treatment group (n=50) and control group (n=50). The treatment group drank orange juice 400 ml (about potassium 600 mg) per day, while the control group drank the same volume of water. Their defecation in 7 d was recorded. Results Compared with those in control group, the frequency of defecation increased (P<0.01), The Bleijenberg score and Bristol score both decreased (P<0.05) in the treatment group. There was no significant difference in incidence of major adverse cardiac events between these groups (P>0.05). Conclusion Potassium-rich diet plays an important role in prevention of constipation in elderly patients with CHD during hospitalization.

Aim To detect the effect of Bio on impro-ving insulin resistance and explore its molecular mech-anism. Methods The HepG2 liver cells were derivat-ed by high concentration insulin to establish the insulin resistance cell model, and the cells were intervened by Bio. The glucose consumption was measured by glu-cose oxidase and peroxidase ( GOD-POD) assay. The expression of PPARγmRNA was detected by RT-PCR. The expression of PPARγ protein was detected by Western blot method. Results The glucose consump-tion was significantly decreased in the insulin resist-ance cells after incubated with 1 . 72 × 10 -5 mol · L-1 insulin ( P<0. 05 ) . 10 -5 ,10 -6 ,10 -7 mol · L-1 Bio increased the glucose consumption 135%,62%,39%separately in the insulin resistance cells. RT-PCR a-nalysis of PPARγ showed that Bio raised the PPARγmRNA. Western blot analysis displayed that the pro-tein of PPARγ with Bio was increased. Conclusion Bio can improve the insulin resistance of the HepG2 cells, and the molecular mechanism may be relevant with raising PPARγ expression.

Objective To analyze the popular characteristic and drug resistance of Pseudomonas aeruginosa in a hospital of Guiy-ang from January 201 1 to December 2013.Methods The distribution characteristic and drug resistance of Pseudomonas aeruginosa isolated from clinical samples from January 201 1 to December 2013 were analyzed retrospectively.Results A total of 642 strains of Pseudomonas aeruginosa were isolated for three years in our hospital from January 201 1 to December 2013,there was 57.0% isola-ted from sputum specimens,and 27.9% isolated from excreta of wound.The infected endemic area distribution was made up of Or-thopedic Surgery,ICU,Geriatrics Department and Respiratory Department accounting for 22.9%,20.1%,18.8% and 1 5.9% re-spectively.Pseudomonas aeruginosa was most sensitive to polymyxin bacillosporin.The drug resistance rates to Trimethoprim,Am-picillin and Cefazolin were all 100.0%.The drug resistance rates to Ampicillin/sulbactam and Ceftriaxone were 90.0%. Conclusion Pseudomonas aeruginosa is the main cause of lower respiratory tract infections in patients and wound infection and show serious multi-drug resistant,so it is necessary to use drugs reasonably according to the drug susceptibility results.

Objective To investigate the application of Follow-up System in health management for the patients after percutaneous coronary intervention (PCI). Methods 100 patients underwent PCI were divided into study group (n=50) and control group (n=50). The control group received routine follow-up and the study group was followed up with the direction of Follow-up System. The incidence of adherence to medication after discharge and awareness of risks of coronary heart disease were recorded 6 and 12 months after discharge. Results The incidence of adherence to medication decreased in the control group (P<0.05) after discharge, but was stable in the study group (P>0.05). Awareness of risks of coronary heart disease increased in the study group 12 months after discharge (P<0.01), but was stable in the control group (P>0.05). Conclusion Follow-up System may help to improve the compliance and awareness in health management in the patients after PCI.

Objective To investigate whether Ulinastatin (UTI) would minimize the systemic inflammatory response,lessen cardiac dysfunction and protect neurons against injury in hippocampus CA1area after restoration of spontaneous circulation (ROSC). Methods Animal models of cardiac arrest were established in 24 New Zealand rabbits,and those animals were randomly (random number) divided into control group and UTI treated group after ROSC.Changes in the levels of plasma inflammatory cytokines TNF-α and IL-6 were assayed before cardiac arrest and 4,8,12 and 16 hours after ROSC.Cardiac function including FS,EF and E/A were observed with ultrasonography before cardiac arrest and 4,8,12 and 16hours after ROSC,and viable and apoptotic neurons in hippocampus CA1 area and infiltrations of MPO positive cells in myocardium,cerebrum,liver,kidney and intestine were counted 72 hours after ROSC.The t-test or Mann-Whitney rank sum test was used to verify the specified theoretical distribution functions of the biomarkers tested by Kolmogorov-Smirnov test,POST HOC test was used for the multiple comparisons,and Pearson correlation analysis was used to investigate the correlation between inflammatory cytokines and cardiac function. Results The levels of TNF-α and IL-6 in UTI group were lower than those in control group as those data got 4,8,12 and 16 hours after ROSC (P <0.05).EF and E/A in UTI treated group were higher than those in the control group as those data got 4,8,12 hours after ROSC.FS values obtained 4 h and 8 hours after ROSC were higher in UTI group than those in control group ( P < 0.05 ).The Pearson correlation analysis showed that the levels of TNF-α and IL-6 significantly correlated with EF after ROSC.The number of viable neurons in CA1 area of control group was ( 13.22 ± 0.97) which was lower than that in UTI group ( 16.89 ± 1.45 ) ( P =0.003 ),while the number of apoptotic neurons in hippocampus CA1 area was higher in control group than that in UTI group (15.67 ± 1.37) vs.(13.67 ± 1.03 ) (P =0.019).The numbers of MPO positive cells were significantly lower in liver,kidney and intestine in group UTI than those in control group. Conclusions UTI could inhibit the infiltration of MPO positive cells in liver,kidney and intestine,decreasing the levels of TNF-α and IL-6 in plasma,in turn lessening cardiac dysfunction and protecting neurons from injury in hippocampus CA1 area after ROSC of New Zealand rabbits.
