In order to obtain the fungicides with minimal impact on efficiency of mycorrhizal symbiosis, the effect of five fungicides including polyoxins, jinggangmycins, thiophanate methylate, chlorothalonil and carbendazim on the growth of medicinal plant and efficiency of mycorrhizal symbiosis were studied. Pot cultured Glycyrrhiza uralensis was treated with different fungicides with the concentration that commonly used in the field. 60 d after treated with fungicides, infection rate, infection density, biomass indexes, photosyn- thetic index and the content of active component were measured. Experimental results showed that carbendazim had the strongest inhibition on mycorrhizal symbiosis effect. Carbendazim significantly inhibited the mycorrhizal infection rate, significantly suppressed the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. Polyoxins showed the lowest inhibiting affection. Polyoxins had no significant effect on mycorrhizal infection rate, the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. The other three fungicides also had an inhibitory effect on efficiency of mycorrhizal symbiosis, and the inhibition degrees were all between polyoxins's and carbendazim's. The author considered that fungicide's inhibition degree on mycorrhizal effect might be related with the species of fungicides, so the author suggested that the farmer should try to choose bio-fungicides like polyoxins.

OBJECTIVETo observe the differences of therapeutic effect in primary trigeminal neuralgia (PTN) of hyperactive of liver yang type treated by deep and shallow puncturing at Xiaguan (ST 7).
METHODSSixty-three cases of PTN of hyperactive of liver yang type were randomly divided into a deep puncturing group (32 cases) and a shallow puncturing group (31 cases). Xiaguan (ST 7) of affected region, Hegu (LI 4) and Taichong (LV 3) of bilateral sides, Cuanzhu (BL 2), Sibai (ST 2) and Jiachengjiang (Extra) relevant to the affected branch of nerve stem were selected in both groups. In deep puncturing group, Xiaguan (ST 7) was punctured to the depth of spheno-palatine ganglion (SPG); Cuanzhu (BL 2), Sibai (ST 2) and Jiachengjiang (Extra) were respectively punctured to the depth of supraorbital foramen, infraorbital foramen and mental foramen. In shallow group, routine puncturing was applied; the needles were connected with G6805 electric acupuncture apparatus, and switched on for 30 min every time; the treatment was applied every other day. Pain index, traditional Chinese medicine symptoms index and clinical therapeutic effect were observed after 2 courses of treatment.
RESULTSIn deep puncturing group, the VAS scores and the traditional Chinese medicine symptoms scores (pain degree, pain frequency, upsetting, conjunctival congestion, bitter mouth and hypochondriac pain) after treatment were much more lower than those before treatment (all P < 0.01); in shallow puncturing group, except hypochondriac pain (P > 0.05), other indices above after treatment were obviously lower than those before treatment (P < 0.01, P < 0.05). Compared with the indices in both groups after treatment, the VAS scores, the pain degree, conjunctival congestion and total scores of traditional Chinese medicine symptoms in deep puncturing group were more significant (all P < 0.05). The total effective rate was 93.8% (30/32) in deep puncturing group, superior to that of 87.1% (27/31) in shallow puncturing group (P < 0.05). No any adverse reaction was observed in both groups.
CONCLUSIONThe therapeutic effect of trigeminal neuralgia of hyperactive of liver yang type treated with electroacupuncture is remarkable, and deep puncturing at Xiaguan(ST 7) to SPG is more effective than routine puncturing.

OBJECTIVETo explore the effect of Yiqi Huoxue recipe (YHR), a Chinese herbal medicine for supplementing Qi, activating blood circulation to remove stasis, on vascular extracellular matrix (ECM) remodeling and its molecular mechanism.
METHODSVascular smooth muscle cell (VSMC) proliferation activity and collagen turnover rate were detected by 3H-TdR test and hydroxyproline amount determined by 3H-Pro incorporation. Expression activity of MMP-2 and osteopontin genes was detected by Northern blotting and MMP-2 zymography analysis.
RESULTSYHR could markedly inhibit VSMC collagen synthesis stimulated by blasic fibroblast growth factor (bFGF) and lower the collagen turnover rate induced by vascular de-endothelialization. The expression level of MMP-2 and osteopontin genes was down-regulated by YHR in cultured VSMC and vascular wall with endothelial injury, and VSMC proliferation was inhibited by the serum obtained from YHR treated rats. Removing protein from the drug serum made no change on the effect of YHR to VSMC.
CONCLUSIONYHR could inhibit and/or retard ECM remodeling through regulating the expression of MMP-2 and osteopontin genes and lowering the collagen turnover rate.

Objective To investigate the effect of prolonged stroboscopic illumination exposure on the growth of eyeball of guinea pig. Methods Thirty 2-week-old guinea pigs were randomized into three groups ( n=10 for each) . Two strobe-reared groups were raised with 20 Hz sinusoidal and 20 Hz square wave stroboscopic illumination, respectively. The control group received usual light illumination. The illumination intensity was 500 lux. All animals underwent refraction and biometric measurements prior to and after 2, 4, 6 and 8 weeks of treatment. Finally, flash electroretinograms were com-pared, and retinal microstructures were examined. Results There was a significant correlation between refractive errors and axial eye elongation, and myopia increasing was observed with eye elongation. After 8 weeks of treatment, the animals raised in 20 Hz sinusoidal and 20 Hz square wave stroboscopic illumination were (-0. 75 ± 0. 79)D and (-1. 50 ± 0. 91) D more myopic than the group raised in continuous illumination. The implicit time of the a-wave was delayed by 3. 8 and 7. 9 ms, respectively. No significant difference was found in retinal ultrastructures among the three groups. Conclusions Chronic exposure to 20 Hz sinusoidal or square wave stroboscopic illumination alters the emmetropization of the guinea pig eye to some extent.

AIMTo investigate the effect of paraventricular nucleus (PVN) stimulation and the c-fos expression within PVN and nucleus tractus solitarius (NTS) of the rat following gastric ischemia/reperfusion injury (GI/RI).
METHODSThe rat celiac artery was clamped for thirty minutes and reperfused for sixty minutes, using Fos immunohistochemical method (ABC method) examined the c-fos expression within PVN and NTS.
RESULTS(1) Both electrical and chemical stimulation of the PVN obviously attenuated the GI/ RI. (2) Bilateral electrolytic lesion of NTS could eliminate the protective effect of electrical stimulation of the PVN. (3) The Fos-like immunoreactive neurons were increased in bilateral PVN and NTS by GI/RI.
CONCLUSIONThe function of PVN and NTS could be affected by the GI/RI noxious stimulation. PVN, NTS were involved in the regulation of GI/RI.
