Objective: To investigate the effect of electroacupuncture (EA) on cognitive function in D-galactose (D-gal)-induced aging rats, and the correlation between the effect and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3)-ASC-Caspase-1 signaling pathway. Methods: Forty-six male Sprague-Dawley (SD) rats were randomly divided into a control group (n=10), a model group (n=12), an EA-7 d group (n=12) and an EA-21 d group (n=12). Except the control group, the other three groups received 42 consecutive days of intraperitoneal injection of D-gal to establish aging rat models with cognitive dysfunction. The control group received the same amount of normal saline via intraperitoneal injection. Two EA groups were given EA therapy for 21 consecutive days (began from the 22nd day of modeling) or 7 consecutive days (began from the 36th day of modeling) accordingly at Dazhui (GV 14), Baihui (GV 20), Shenshu (BL 23) and Zusanli (ST 36). After modeling/ intervention, all four groups received behavioral evaluations by Morris water maze (MWM) test, novel object recognition (NOR) test and step-down passive avoidance (SDPA) test followed by the Western blot (WB) detection of the expression levels of hippocampal NLRP3 inflammasome-associated proteins NLRP3, ASC and Caspase-1. Results: MWM (place navigation test, PNT) results showed that the escape latency in the model group was significantly longer than that in the other three groups (P<0.05), and there was no significant difference among the other three groups on the 1st day of the test (P>0.05). From the 2nd day to the 4th day of the test, there was no significant difference between the EA-21 d group and the control group (P>0.05) in the escape latency; the escape latency was significantly shorter in the EA-21 d group than in the model group and the EA-7 d group (P<0.05). MWM (spatial probe test, SPT) results showed that the time spent in the target quadrant was significantly shorter and platform crossover number was significantly lower in the model group than in the other three groups (P<0.05). The time spent in the target quadrant was longer in the EA-7 d group than in the model group (P<0.05), but was shorter than that in the control group and the EA-21 d group (P<0.05). There was no significant difference in the swimming speed among the four groups (P>0.05). NOR results showed that there was no significant difference in the recognition ratio between the EA-7 d group and the EA-21 d group (P>0.05), and the recognition ratio was significantly higher in the two EA groups than in the model group (P<0.05), but was lower than in the control group (P<0.05). SDPA results showed that the electric shock number was higher in the model group than in the other three groups (P<0.05), and the differences among the other three groups were statistically insignificant (P>0.05). The model group had the shortest step-down latency, followed by the EA-7 d group, the EA-21 d group and the control group in order (P<0.05). The WB results indicated that the expression level of NLRP3 was significantly lower in the control group and the EA-21 d group than in the model group and the EA-7 d group (P<0.05). The expression levels of ASC and Caspase-1 were significantly higher in the model group than in the other three groups (P<0.05), and there was no significant difference among these three groups (P>0.05). Conclusion: NLRP3 inflammasome may be involved in the development of cognitive decline in aging rats; 7 consecutive days of EA intervention can partially improve the cognitive impairment in aging rats though the effect is rather limited; 21 consecutive days of EA intervention may improve the learning and memory abilities in aging rats via downregulating the expression levels of NLRP3 inflammasome-associated proteins in hippocampus.

In this paper, the process performance indexes (PPIs) P(p) and P(pk) were introduced and applied to evaluate the process capability and quality consistence of Chinese medicine products. The historical quality analysis data of Qingkailing injection were collected and taken as the research object. The confidence intervals of P(p) and P(pk) were estimated based on the Bootstrap sampling methods. Results showed that the value and width of the confidence interval P(p) of were smaller that of P(pk) suggesting that the P(pk) index was more sensitive than P(p) in process capability analysis. Within the production period concerned, the P(pk) values estimated from different quality indexes of Qingkailing injection, such as baicalin, cholic acid, geniposide and total nitrogen, were 1.122, 2.055, 1.564 and 0.891, respectively. It could be found that the cholic acid had the highest process capability, followed by the geniposide and baicalin. The total nitrogen had the lowest process capability, indicating that it is necessary to reinforce the quality management of total nitrogen related manufacturing processes. The case studies demonstrate the effectiveness and feasibility of PPIs, which are convenient to be used in production practice of Chinese medicine.

OBJECTIVETo investigate the inhibitory effects of OMT on TGF-β1-induced CFBs proliferation, and then explore the mechanism.
METHODThe experiment was randomly divided into 6 groups as following: control group (serum free DMEM), model group (20 μg x L(-1) TGF-β1), OMT low dose group (1.89 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT medium dose group (3.78 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT high dose group (7.56 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), SB203580 group (p38MAPK blocking agent, 1 x 10(-5) mol x L(-1) + 20 μg x L(-1) TGF-β1). Vimentin of CFBs was identified by immunocytochemical methods, α-SMA of myFBs as well. Inhibitory effects of OMT on CFBs proliferation was detected by the MTT assay. Picric acid Sirius red staining was analyzed collagen type I and collagen type III deposition. Western blot was determined the expression of p38MAPK, p-p38MAPK, collagen type I and collagen type III.
RESULTMTT results showed that OMT significantly inhibited CFBs proliferation induced by TGF-β1 (P < 0.01) α-SMA immunocytochemical experiments suggested that OMT could protect against the CFBs proliferation. OMT could significantly decrease the deposition of collagen type I and collagen type III by Western bloting and picric acid Sirius red staining. Western blot results showed that TGF-β1 enhanced p38MAPK phosphorylation, however OMT attenuated the phosphorylation of p38MAPK induced by TGF-β1 (P < 0.01).
CONCLUSIONOMT can inhibit the CFBs proliferation induced by TGF-β1, and its mechanism may be involved in inhibiting p38MAPK phosphorylation.

The seeds of Rabdosia rubescens were as the materials to research the impacts of different lead (Pb2+) concentrations(0, 135, 270, 540, 1 080 mg x L(-1)) on seed germination and seedling growth. The results show that: Low concentration of lead had no obvious effect on early germination of the seed, the germination vigor and germination speed were lightly higher but not significantly differed at the level of Pb concentration 135 mg x L(-1) with control group; Mid-high concentration of Pb solution (270-1 080 mg x L(-1)) significantly inhibited the seed germination and seedling growth, which reduced the seed germination rate, germination vigor, germination index, embryo root length and shoot length, growth index with increasing of Pb concentrations. There was a inhibitory effect on embryo shoot length and root length at mid-high lead concentrations stress, and stronger inhibitory effect on root , which was more sensitive than shoot to Pb stress(P < 0.05). Pb bioaccumulation coefficient (BC) was 0.76-2.59, increased with concentration of Pb; Pb enrichment in seedling mainly caused the growth inhibition. The fitting model predictive analyses show, the critical concentration of Pb, which causes the germination rate and biomass fresh weight reducing 10%, is 195.18, 101.65 mg x L(-1).
