OBJECTIVETo explore the effect differences between twirling-rotating reinforcing and reducing technique of acupuncture on cardiac damage in spontaneous hypertensive rats (SHR).

METHODSSixty male 11-week-old SHR were randomly divided into four groups: a model control group (group A), a twirling-rotating reinforcing technique group (group B), a twirling-rotating reducing technique group (group C) and a needle retaining group (group D), 15 rats in each one. In addition, twelve male 11-week-old Wistar rats were used as a blank control group (group E). Acupuncture was not used in group A and group E, only with grasp, capture and binding stimulation that was also adapted in the rest groups. Rats in the group B were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reinforcing technique for 1 min and then the needles were retained for 9 min; rats in the group C were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reducing technique for 1 min and then the needles were retained for 9 min; rats in the group D were treated with acupuncture at "Taichong" (LR 3) but without any technique and then needles were retained for 10 min. Before and after acupuncture, blood pressure monitor was used to measure the rats' systolic pressure and diastolic pressure every 6 days. Twenty-eight days after the treatment, HE and Masson staining were adopted to observe the status of left ventricular hypertrophy and myocardial fibrosis. ELISA method was applied to test the content of endothelin-1 (ET-1). PCR semiquantitative method was used to analyze Type I and III collagen mRNA in the left ventricular.

RESULTS(1) Blood pressure: after the treatment, the systolic pressure and diastolic pressure were both increased in the group A and the group B (P < 0.05); while the two pressures were both lowered in the group C and the group D (P < 0.05), which was more obvious in the group C (P < 0.05). (2) According to HE and Masson staining, except for the group E, the myocardial hypertrophy and fibrosis could be found in the rest groups, in which the group C was the modest, followed by the group D, while the group A and the group B were more severe. (3) Concentration of ET-1: there were differences of concentration of ET-1 among 5 groups (P < 0.05), and the concentration value from high to low was the group A, B, C, D and E. (4) Type I collagen mRNA: the difference of level of Type I collagen mRNA between group C and D was not statistically significant (P > 0.05); compared with the group A and B, the level was lower in the group C; the level was the lowest in the group E. Type III collagen mRNA: the difference between the group A and B was not statistically significant (P > 0.05); compared with the group A, B and D, the level was lower in the group C.

CONCLUSIONThe twirling-rotating reducing could reduce the systolic pressure and diastolic pressure in SHR, effectively prohibit the production of ET-1 and expression of Type I and III collagen mRNA, and it has more obvious inhibiting effect on Type III collagen mRNA. There is biological effect difference between twirling-rotating reinforcing and reducing technique.

Objective To observe the effects of the compatibility of Radix Astragali and Radix Angelicae Sinensis in different proportion on hemodynamic and balance of Th1/Th2 cells of Qi deficiency and blood stasis rat model. Methods Qi deficiency and blood stasis rats were caused by restricted diet, forced swimming and norepinephrine subcutaneous injecting, and treated by compatibility of Radix Astragali and Radix Angelicae Sinensis in different proportion of 5∶1, 3∶1, 1∶1 and 1∶2 for 21 days. The indexes of hemorheology were detected with hemorheological analyser, and the level of IFN-γand IL-4 in serum were tested by ELISA. Results Compared with model group, the compatibility of Radix Astragali and Radix Angelicae Sinensis in proportion of 1∶1, 3∶1 and 5∶1 groups reduced the low shear blood viscosity. The spleen index of model group decreased, and compatibility of Radix Astragali and Radix Angelicae Sinensis in 5∶1 proportion group increased spleen index. The level of IL-4 increased and IFN-γ decreased in the serum of model group, the compatibility of Radix Astragali and Radix Angelicae Sinensis in proportion of 3∶1 group increased the level of IFN-γ. Astragalus angelica 5∶1 group decreased the level of IL-4 and increased the level of IFN-γ. Conclusion The compatibility of Radix Astragali and Radix Angelicae Sinensis can improve hemorheology, adjust the balance of Th1/Th2 cells of Qi deficiency and blood stasis rats. The effects were better when Radix Astragali’s dosage greater than that of Radix Angelicae Sinensis, and the group of 5∶1 proportion was the best.

The angiotensinogen(AGT) expression and angiotensin Ⅱ (AngⅡ ) secretion levels in cultured SD rat mesangial cells were determined. High glucose up-regulated AGT mRNA(0. 29±0.07 vs 0. 20±0. 05,P< 0.05)and protein(0.66±0.23 vs 0.37±0. 15,P<0.05) expression and Ang Ⅱ secretion [(9.85±2.08 vs 7.50± 1. 51) pg/ml,P<0. 05]levels, which were down-regulated by pyrrolidine dithiocarbamate( PDTC) treatment via inhibiting NF-κB activity.

Objective To observe the tolerance of contemporaneous multiplane operations in obstructive sleep apnea-hypopnea syndrome(OSAHS). Methods Twenty-three patients were enrolled. According to the different obstructive level, the different operations were chosen to complete upper airway reconstruction in contemporaneous operation group (group A, 13 patients). In the simple palatopharynx level obstructive group (group B, 10 patients), bilateral tonsillectomy and H-UPPP was chosen. Results The operation time in group A was significantly longer than that in group B:(121.0 ± 35.4) min vs.(80.7 ± 25.3) min, P<0.01. The hospital days and adverse events in two groups had no significantly difference (P>0.05). Conclusions Individual therapeutic schedule for OSAHS patients should be formulated. Operating the different obstructive levels simutaneously, which would solve upper airway occlusion and complete the upper airway reconstruction at the same time. No more adverse events happen, compared with the simple palatopharynx level obstructive group, though the operation time may be longer.

In this study, the optical data of tongue color of different syndromes in primary hepatic carcinoma (PHC) were detected by optical spectrum colorimetry, and the chromaticity of tongue color was compared and analyzed. The tongue color characteristics of different syndromes in PHC and the relationship between different syndromes and tongue color were also investigated.

To reveal the variation of polysaccharides and alcohol-soluble extract contents of Dendrobium officinale, the polysaccharides and alcohol-soluble extracts contents of three D. officinale strains were determined by phenol-sulfuric acid method and hot-dip method, respectively. The results showed that the contents of polysaccharides and alcohol-soluble extracts and their total content were significantly different among D. officinale samples collected in different periods, and the variations were closely related to the phenology of D. officinale. Additionally, the quality variation of polysaccharides was closely related to the flowering of D. officinale, while the alcohol-soluble extracts was closely associated to the formation and germination of buds. According to the dynamic variation of these two compounds, it is more reasonable to harvest D. officinale at biennials pre-bloom than at specific harvesting month considering polysaccharides content. It is better to harvest before the germination of buds considering alcohol-soluble extracts. While with regards to both polysaccharides and alcohol-soluble extract, it is better to harvest this plant at the period from the sprouting to pre-bloom next year.

To reveals the effects of tree species on polysaccharides content of epiphytic Dendrobium officinale. The polysaccharides content of D. officinale attached to living tress in wild or stumps in bionic-facility was determined by phenol-sulfuric acid method. There were extremely significant differences of polysaccharides content of D. officinale attached to different tree species, but the differences had no relationship with the form and nutrition of barks. The polysaccharides content of D. officinale mainly affected by the light intensity of environment, so reasonable illumination favored the accumulation of polysaccharides. Various polysaccharides content of D. officinal from different attached trees is due to the difference of light regulation, but not the form and nutrition of barks.
