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.

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 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.

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 variation of biomarker of coagulation, anti-coagulation, fibrinolysis in elderly critical patients and find out whether they are related to the disease severity. Methods Sixty-seven patients were no less than 60 years old. Eligible criteria: coincidence with the diagnostic criteria of systemic inflammatory response syndrome (SIRS) and APACHE Ⅱ score was no less than 10 scores. Blood sample was drawn from the venous for the test of biomarker (APTT, PT, TT, D-D, Fib, AT-Ⅲ , PC, PAI-1). According to the existent status,all the patients were divided into two groups:survival group (43 cases) and death group(24 cases) ,meanwhile,according to the diagnostic criteria of MODSE,all the patients were divided into MODSE group (30 cases) and non-MODSE group (37 cases). Results There were significant differences in APACHE Ⅱ score between MODSE group and non-MODSE group, survival group and death group [(25.83 ± 1.19) scores vs(18.1±20.73) scores and(18.81±0.72) scores vs(26.50 ± 1.42) scores](P <0.01). The PT and D-D in MODSE group anti death group were higher than those in non-MODSE group and survival group, the differences were significant (P <0.05),while the activity of AT-Ⅲand PC in MODSE group and death group were lower than those in non-MODSE group and survival group, the differences were significant (P <0.05). The PT,D-D and PAI-1 were positively correlated to APACHE Ⅱ score (related coefficients were 0.328, 0.308, 0.335,P <0.05). The AT-Ⅲ and PC were negatively correlated to APACHE Ⅱ score (related coefficients were -0.469, -0.559,P <0.01). Conclusions The abnormality of eoagnlation-fibfinolysis system exists in elderly critical patients. The extended PT, elevated D-D and PAI-1 ,descended PC and AT-Ⅲ are the hints of disease severity and poor prognosis.

Objective To evaluate the effects of Ulinastatin (UTI) on the expressions of TNF-α,IL-6 and neurons apoptosis in cerebral cortex of rats after cardiopulmonary resuscitation (CPR).Methods Thirty-six healthy male adult Wistar rats were induced ventricular fibrillation untreated for 7 min and then received CPR.The animals were infused UTI 100 000 U/kg or phosphate-buffered solution (PBS) at once after ROSC.At 2,4 and 8 h after ROSC,cerebral cortex were removed to determine the mRNA expressions and levels of TNF-α protein and IL-6 protein,the translocation ratio of NF-κB p65 from cytoplasm to nucleus and the apoptotic neurons.Results The plasma levels of TNF-α (ng/mL) in animals of UTI group were (17.7 ± 1.4),(21.9 ± 2.1) and (17.1 ± 0.6) at 2,4 and 8 h after ROSC respectively,and significantly lower than those in PBS group at the given intervals.Mean while,the levels of IL-6 (ng/mL) were (208.9 ± 14.1),(281.5 ±25.9) and (251.8 ± 15.3) at 2,4 and 8 h after ROSC respectivèly in animals of UTI group,and lower than those in PBS group.The expressions of TNF-α mRNA and IL-6 mRNA and protein levels of TNF-α and IL-6 in UTI group were both lower than those in PBS group at given intervals,respectively.The translocation ratio of NF-κB p65 from plasma to nucleus in PBS group at each given interval after ROSC was significantly higher than that in UTI group.The number of viable neurons in cerebral cortex in UTI group was higher than that in PBS group,while the number apoptosis neurons was fewer in UTI group.Conclusions UTI attenuated the general inflammatory response after ROSC in rat,decreased the activation of NF-κB pathway,and subsequently attenuated the expression of TNF-α and IL-6,and finally decreased the neurons apoptosis.

Objective To discuss the relationships between qi-arrival and mind-control, qi-arrival and qi-regulation, and to define qi-arrival by tracing the relevant records in Nei Jing (Classic of Internal Medicine) and Nan Jing (Classic of Difficult Issues). Method Thirty-seven relevant ancient books of the two classics were reviewed and the notes by WANG Bing, MA Shi, and YANG Shang-shan were referred. Result Mind-control requires the spirits of the practitioner, patient and environment, as well as observing and waiting for the arrival of qi. Regarding qi-regulation, theories involve that qi-arrival achieves same reinforcing and reducing effect as qi-regulation, qi-regulation is elucidated from the correct location of acupoint, proper needling depth and direction, and to regulate qi by observing the arrival of qi. Besides, the changes of internal and external environments also influence qi-arrival via qi-regulation and mind-control. Conclusion Qi-arrival is closely related to mind-control and qi-regulation in obtaining, differentiation, and adjustment. Mind-control and qi-regulation assist each other through the whole acupuncture process, which is the core of qi-arrival.
