Objective To investigate whether catalpol is the active component responsible for the Yin tonic effect of Radix Rehmanniae.Methods Young NH mice were injected with triiodothyronine to produce the hyperthyroidism model,while old mice were used as the model of natural aging.The single point radioligand binding assay was carried out to determine the ?-adrenergic receptor density and M-cholinergic receptor density.The learning ability(short term memory) was determined by the Y-maze avoidance test. Results In the ?-adrenergic receptor experiment,the densities were(15.7?5.2) and(20.9?7.2) fmol/mg protein in normal control group and in T3 control group(P

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.

AIMTo examine whether reproductive hormones play a role in the association between body mass index (BMI) and semen quality.

METHODSSemen quality and testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and estradiol (E(2)) were evaluated in 990 fertile males with age 38.9 +/- 9.7 (mean +/- SD) years recruited from the Chinese general population in 2001 and 2002.

RESULTSSemen quality was reduced among underweight (BMI < 18.5) compared with normal (BMI 18.5-24.9) and overweight (BMI 25.0-29.9), but the associations were independent of reproductive hormones. After adjustment for the potential confounders, underweight men had reductions in sperm concentration (22.4 X 10(6)/mL), total sperm count (52.9 X 10(6)) and percentage of normal sperm forms (6.9%) compared with men with normal BMI. Being underweight may be a risk factor for low sperm concentration (OR: 4.68, 95% confidence intervals [CI]: 2.01-10.91). Otherwise, being overweight may be a protected factor for low sperm concentration (OR: 0.25; 95% CI: 0.08-0.83) and low total sperm count (OR: 0.37, 95% CI: 0.15-0.87).

CONCLUSIONLow BMI was associated with reduced semen quality. The associations between BMI and semen quality were found statistically significant even after adjustment for reproductive hormones. Reproductive hormones cannot explain the association between BMI and semen quality.

In order to detect coagulation factor VIII (FVIII) inhibitor in patients with severe hemophilia A (HA) and preliminarily study the genetic mutation in patients with inhibitor positive. Totally 58 patients with HA (FVIII: C < 1%) were enrolled. FVIII: C activity was measured by one-stage coagulation assay. FVIII inhibitor was screened by using APTT method and FVIII inhibitor in screened positive patients with HA was quantitatively analyzed by using Bethesda method. Using genomic DNA as template, 12, 14, 16 exons of FVIII in screened positive patients were amplified, and the mutations of amplified products were detected by direct sequencing. The results indicated that the FVIII inhibitor could be detected in 4 patients (6.9%) from 58 HA patients, no gene mutations in 12, 14, 16 exons of FVIII were found. It is concluded that the positive rate of FVIII inhibitor in HA patients is lower than that reported in literature. The causes of inhibitor production needs to further investigate.

Due to ineffectiveness and side effects of existing analgesics, chronic pain has become one of the most complex and difficult problems in the clinic. Monoacylglycerol lipase (MAGL) is an essential hydrolase in the endocannabinoid system and has been identified as a potential target for the treatment of pain. In the present study, we designed and synthesized twelve tanshinone IIA analogs and screened their activity against MAGL. Selected compounds were tested for analgesic activity in vivo, with the acetic acid writhing test model. Among the test compounds, compound III-3 (IC 120 nmol·L) showed significant activity against MAGL and ameliorated the clinical progression in the mouse pain model. Additionally, compound III-3, substitution with N-methyl-2-morpholinoacetamide, demonstrated improved solubility relative to tanshinone IIA.
