OBJECTIVETo dynamically assess drug targeting of Yougui Pill (YP) and Zuogui Pill (ZP) using infrared thermography.

METHODSIn this self-control experiment, five healthy volunteers were recruited. By using infrared thermography 10 to 11 thermal images of different body locations were taken from each participant after they took warm water, YP, ZP, and their dissembled prescriptions at 30, 70, 100, 130, and 160 min, respectively. The heat values in the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) were statistically analyzed after scanning for 125 times.

RESULTSAdministration of YP and its disassembled prescriptions enhanced the heat value of the locations of the Du channel and Shenque (CV8), but did no enhance the heat value of the lower quadrant abdomen at 30 min. Administration of ZP and its disassembled prescriptions reduced the heat value in the locations of the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) at each time point.

CONCLUSIONThe drug targeting of ZP and YP focused on the locations of the Du channel and Shenque (CV8), not on the locations of the lower quadrant abdomen or uterus.

Objective:To explore the resource of rice bran by comparing antioxidative activities and growth promotion of Bacillus bifidus between supernatant of formented rice bran(RBF) by Bacillus natto and water extract of rice bran(RBW) . Method:The reducing capacity the?OH and ??O 2 scavenging capacity and the inhibitory effect to oxidize lard were determined in vitro. The growth promotion for Bacillus bifidus by photodensity with simulated condition was investigated in vivo. Results:RBF and RBW had antioxidant activity in vitro. The IC50 of scavenging?OH and ??O 250 of RBF was 3.55 mg/ml and 23.5 mg/ml,0.3 and 10 folds higher than that of RBW respectively. In inhibiting oxidation of lard,RBF had a little higher antioxidative activities than RBW,near VE. RBF and RBW could promot growth of Bacillus bifidus by 65.2% and 17.8% respectively. By enzymatic digestion,the promotive rate of RBF was still 51.6%. Conclusion:RBF had higher antioxidant activity and growth promotion to Bacillus bifidus.

Seven emotions generation relates to the interaction between individual and external objective matters,which is accompanied with interaction between internal desire and external matters.The activity of seven emotions bases on essence of zang-fu organs,being regulated by five zang viscera.Heart is the upstream controller,liver is the key organ to maintain normal emotionds,spleen and stomach is the hub of emotional activities,lung is the auxiliary organ, kidney is origin of emotional generation.Five zang viscera's cooperation and interaction generate the seven emotions.

BACKGROUND:There is a very close relationship between osteoporosis and periodontal disease in postmenopausal women, but the mechanism remains unclear. OBJECTIVE:To investigate the expression of nuclear factor-κB in the alveolar bone andinterleukin-17 in the serum and gingiva in the mouse model of osteoporosis caused by ovariectomy. METHODS:Female mice aged 3 months were randomly divided into ovariectomy and sham operation groups. At 6 months after surgery, the mouse models were evaluated histologically on the submandibular bone and thigh bone stained with hematoxylin and eosin. In the submandibular bone, the expression levels of OCN and Runx2 were detected by RT-PCR, and the expression level of nuclear factor-κB was detected by immunohistochemical staining and western blot assay. Besides, the expression level of interleukin-17 in the serum and gingival homogenate was evaluated using Cytometric Beads Array. RESULTS AND CONCLUSION:The thigh bone in the ovariectomy group revealed the thin cortical bone, enlarged marrow cavity, and increased resorption lacunae, as well as fewer, thinner trabeculae with lower density and irregular structure. Compared with the sham operation group, the expression levels of OCN and Runx2 in the alveolar bone were decreased in the ovariectomy group. The activation of nuclear factor-κB (P65)appeared with P65 positive expression in the submandibular bone in the ovariectomy group, and the relative expression level was higher than that in the sham operation group. The serum level of interleukin-17 in the ovariectomy group was higher than that in the sham operation group, but the level in the gingival tissue showed no significant difference between the two groups. These results indicate that estrogen deficiency after ovariectomy can activate nuclear factor-κB signal pathway to play a role in periodontal osteolysis. However interleukin-17 in the local periodontal tissue may not be a key cytokine to damage the periodontal tissue.

OBJECTIVETo investigate the effects of oxidative stress on the expression of endothelialleukocyte adhesion molecule-1 (ELAM-1) in porcine trabecular meshwork cells and to elucidate the relationship between the expression of ELAM-1 and IL-1alpha.

METHODSPrimary cultured porcine trabecular meshwork cells were cultured without serum and treated with 1 mmol/L H2O2 with or without pretreatment of IL-1ralpha of different concentrations. The expression of ELAM-1 was tested by immunocytochemistry.

RESULTSELAM-1 immunocytochemistry staining was positive in the H2O2-treated porcine trabecular meshwork cells. It was negative in the porcine trabecular meshwork cells pretreated with IL-1alpha of high concentrations (180 microg/ml and 600 microg/ml).

CONCLUSIONSOxidative stress can induce the expression of ELAM-1 in porcine trabecular meshwork cells. In the in vitro cell system, IL-1ralpha of high concentration can inhibit the expression of ELAM-1 induced by oxidative stress.

OBJECTIVETo investigate the effects of estrogen on the activity and subunits expression of cytochrome c oxidase (COX) in mitochondria from genioglossus of chronic intermittent hypoxia (CIH) rat.

METHODSForty-eight male Sprague-Dawley (SD) rats were randomly divided into three groups: the normal control group (NC), the chronic intermittent hypoxia group (CIH) and estrogen plus hypoxia group (E + CIH). Rats in the latter two groups were used to build CIH models (8 h/d, 5 w). In the mean time, rats in NC group and CIH group were injected with sterile olive oil (0.2 ml each time, twice a week), and rats in E + CIH group were injected with estrogen (0.2 mg/kg, twice a week), respectively. At the end of the treatment, the genioglossus of the rat was removed and the mitochondria were isolated by centrifugation program. COX activity was measured with a spectrophotometer. The protein content of COX subunit I and IV was detected by Western blotting analysis, and mRNA expression levels of COXI and COXIV were determined by real-time polymerase chain action.

RESULTSCOX activity in CIH group [(0.143 +/- 0.029) microkat/mg] was lower significantly than that in NC group [(0.273 +/- 0.058) microkat/mg, P < 0.01]; In E + CIH group [(0.203 +/- 0.073) microkat/mg], COX activity was higher than that in CIH group (P < 0.05), but still lower than that in NC group (P < 0.05). Compared with NC group (47.325 +/- 7.502), decreased COXI expression was observed in CIH group (10.789 +/- 8.144, P < 0.01) and E + CIH group (25.593 +/- 11.108, P < 0.01). While in the mean time, the protein content of COXI in E + CIH group was higher than that in CIH group (P < 0.05). There was no significant difference in protein content of COXIV among the three groups (P > 0.05). COXI and COXIV mRNA levels had no significant change among the three groups (P > 0.05).

CONCLUSIONSCIH exposure could decrease mitochondrial COX protein expression and activity in the genioglossus of the rat, while estrogen administration might be beneficial to the recovery of those.

The autophagy is a process of cell survival by lysosomal degradation of damaged organelles and macromo-leular materials. It plays an important role in stable environment. The autophagy of cells is persisted in the patho-physiology of angiogenesis. However,To explore the development of the angiogenesis based on autophagy,is the clinical treatment ideas of the vascular disease.
