OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.

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).

To investigate the effects of DENV infection on the expression of Vascular endothelial growth factor (VEGF) in monocytes, and to explore which innate immune signaling pathway is responsible for VEGF induction. Real-time PCR was used to determine the expression levels of VEGF in DENV-infected THP-1. We found that different serotype viruses (DENV1, DENV2, DENV3) induced the VEGF expression. Moreover, VEGF expression was significantly increased in human primary monocytes infected with DENV 2. In addition, VEGF induction by DENV2 was significantly impaired by knockdown of TLR3 and interferon-beta promoter stimulator 1 (IPS-1), or by inhibition of ERK, JNK or NF-kappaB. These results demonstrated that DENV induced VEGF expression in monocytes, and the activation of TLR3, IPS-1 signal pathways were required for DENV2-triggered VEGF induction, suggesting that VEGF might be a promising therapeutic target for DHF.

AIM To observe the oxidant stress and opoptotic effects of anisodine hydromide (AH) on chronic cerebral hypoperfusion (CCH) rats.METHODS In vivo CCH models were established in adult male SpragueDawley rats by permanent ligation of bilateral common carotid arteries [two-vessel occlusion (2-VO)] surgery.Rats were randomly divided into six groups,sham group,model group,positive group of n-butylphthalide and sodium chloride injection,and AH groups (1.2 mg/kg high-dose group,0.6 mg/kg medium-dose group,and 0.3 mg/kg low-dose group).Antioxidant indices including the activity of SOD,CAT,LDH and iNOS and the content of GSH and NO were measured.In the in vitro trial,PC12 cells were divided into control group,model group,positive group of n-butylphthalide,and AH groups (100 μmol/L high-dose group,50 μmol/L mediumdose group,and 25 μmol/L low-dose group),and the hypoxic models were established by treating PC12 cells with CoCl2.The cells had their release of NO and LDH detected,their cellular apoptosis determined by Hochest 33342 fluorescence staining,and the expression of P53 protein identified by IF (immunofluorescence) and Western blotting method.RESULTS The in vivo trial revealed AH's enhancement in serum SOD activity and inhibition in serum iNOS activityof the CCH rats,and its power in the cerebral GSH and LDH release reduction.The in vitro trial showed the resultant lower LDH and NO release,decreased number of neuro-apoptosis,and inhibited P53 pro tein expression after AH intervention.CONCLUSION The antioxidant and antiapoptotic effects of AH on CCH rats may be associated with down regulation of P53 protein.

Objective To explore the risk factors on the symptoms of lumbar intervertebral disc herniation so as to develop a predictive model for the disease. Methods With a populationbased case-control study, 303 of 50 123 residents were diagnosed as having lumbar intervertebral disc herniation symptoms. 152 cases and 167 healthy controls, matched by gender and age, were randomly chosen as case and control groups. Questionnaires were used to collect information on the exposure to risk factors and logistic predictive model was then established. Results Through non-conditional logistic regression analysis, data showed that the positive family history of lumbar vertebra disorder, lumbar treatment or surgery, mental stress, acute low back injury, permanent work pose, and body mass index ≥23.0 kg/m2 were the risk factors among residents from the countryside. The area under the receiver operator characteristic curve of logistic predictive model was 0.809. When 0.4 was set as the classification cutoff, the total predictive correct rate, sensitivity, and specificity were 74.0%, 73.7%, and 74.3% respectively. Conclusion The occurrence of lumbar disk herniationcan in countryside population was affected by multi-variables including genetic and environmental, and could be predicted with the logistic regression model established by our group.The positive predictive results could be used to alarm the patients and doctors for prevention and treatment of the disease.

OBJECTIVETo select superior mating combinations from different F1 generations of Dendrobium officinale.

METHODTwenty-six superior parents from four provenances were selected to make up 26 mating combinations. The agronomic traits of different F1 generation were measured, counted, and analyzed by DPS software.

RESULTThere were significant differences between different mating combinations among F1 generations. The variation among full-sib families was significantly higher than that among half-sib families, while the variation inside full-sib families was significantly lower than that inside half-sib families. Twelve agronomic traits were simplified into four principal components, of which the accumulative contribution rate was 84.127 3%. Twenty-six mating combinations have been divided into six groups, plants from the fifth and sixth group grew much better than the others.

CONCLUSIONThe selection of parents should be emphasized by using hybrid vigor. There were higher genetic gains and superior uniformity inside families when selection and breeding occurs in full-sib families than in half-sib families. Eight superior full-sib families (83 x 34, 66 x 9, 68 x 2, 91 x 69, 66 x 65, 69 x 91, 17 x 66, 66 x 17) have been selected which showed a good agronomic traits of seedlings.
