In order to find the characteristics of two members of gene family of squaleneexpoxidase (SE) , a quantitative real time PCR method was developed to analyze the expression of Eleutherococcus senticosus SE1 and SE2 gene from different growth periods and in different organs. The result indicated that all the expression of SE2 more than SE1 in the whole growth period and organs of E. senticosus. And in the whole growth period, expression of SE1 showed a low-high-low characteristic. Both expression of SE2 and growth period showed the same trend. The lowest content of the expression was in the roots. SE1 expression have been improved more than SE2 when treated with MeJA. The expression of E. senticosus SE1 and saponins content had significantly positive correlation (P < 0.05) and the correlation coefficients was 0. 858, while the correlation was not significant for SE2. That indicated that SE1 played a key enzyme gene in the biosynthesis of triterpenoidsaponins

OBJECTIVETo compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).

METHODSForty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.38 ± 4.24) and (26.90 ± 3.14) years, with BMIs of (27.77 ± 0.77) and (28.07 ± 2.28) kg/m² and penis lengths of (3.51 ± 0.46) and (3.50 ± 0.59) cm, respectively. The operations were performed under local anesthesia with lidocaine plus ropivacaine mesylate.

RESULTSThe operation time of circumcision was (28.04 ± 2.65) min and that of FDSF was (45.45 ± 3.49) min. At 6 months after surgery, normal penile erection was found in all the patients, the penis length was significantly longer in the FDSF than in the circumcision group ([5.01 ± 0.73] vs [3.70 ± 0.47] cm) , and the rate of satisfaction with penile appearance was markedly higher in the former than in the latter group (3.25 ± 0.71 vs 2.83 ± 0.56).

CONCLUSIONThe foreskin-deglove plus shaft-fix procedure under local anesthesia with lidocaine and ropivacaine mesylate may achieve desirable penile erection and appearance in the treatment of phimosis or redundant prepuce in obese adult patients.

A rapid quantitative component analysis method for biochar based on near infrared spectroscopy (NIRS) technology was established in this study. Near infrared spectra of 163 samples in 10000-3800 cm-1 (1000-2632 nm) range were collected, and the contents of fixed carbon (FC), volatile matter (VM) and ash of samples were analyzed. A partial least square(PLS) model for FC,VM and Ash was established in the optimized model spectral ranges. The factors were optimized and the raw spectra were pretreated by multiple scatter correction and second derivative(MSC+SD) method. Finally,the prediction performance of predictive model was evaluated. The results showed that the PLS model had a good prediction ability,and the predicted coefficient R2pof actual values vs prediction values for FC, VM and Ash were 0.9423,0.9517 and 0.9265, respectively. Root mean square errors of prediction(RMSEP) were 0.1074,0.1201 and 0.1243,and ratios of prediction to deviation(RPD) were 3.51,4.28 and 2.03,respectively. The PLS model has good accuracy and precision for both of FC and VM, and can be used as a quantitative method for FC and VM contents analysis. Nevertheless,PLS model needs to improve the precision for Ash analysis according to RPD value. The method provides a fast and effective technical means for the quantitative analysis of biochar components.

OBJECTIVETo explore the relationship between the -344T/C polymorphism of aldosterone synthase (CYP11B2) gene and essential hypertension in Chinese Mongolian population.

METHODSBy cluster-sampling method, a total of 1575 Mongolian people in Tongliao city of Inner Mongolia were included in this study. And 417 subjects were normotension, 596 subjects were prehypertension and 562 subjects were essential hypertension. A survey was conducted to collect data by personal interview using a standard questionnaire, meanwhile fasting blood samples were drawn. Height, weight, waist circumference, blood pressure, blood-fat indexes and fasting plasma glucose were measured. The variant genotypes of CYP11B2 were identified by PCR assays. The relationship between the -344T/C polymorphism of CYP11B2 gene and essential hypertension were analyzed by multinomial logistic regression model.

RESULTSCrude prevalence of prehypertension among Mongolian people was 37.84% (596/1575) and hypertension was 35.68% (562/1575). The age-standardized prevalence of prehypertension was 38.57% and hypertension was 31.53%. The frequency of the T and C allele was 0.66 (481/728) and 0.34 (247/728) for normotension group, 0.69 (696/1042) and 0.33 (346/1042) for prehypertension group, 0.71 (706/998) and 0.29 (292/998) for hypertension group. The multiple logistic models showed CYP11B2 variant genotypes were associated with prehypertension (TT/CC, OR = 1.33, 95%CI: 0.87 - 2.01; TC/CC, OR = 1.74, 95%CI: 1.13 - 2.67; TC + TT/CC, OR = 1.49, 95%CI: 1.01 - 2.22); CYP11B2 variant genotypes were associated with hypertension (TT/CC, OR = 1.70, 95%CI: 1.07 - 2.70; TC/CC, OR = 1.59, 95%CI: 0.98 - 2.50; TC + TT/CC, OR = 1.66, 95%CI: 1.06 - 2.58).

OBJECTIVETo explore the mechanism of electroacupuncture(EA) at "Fenglong" (ST 40) in hyperlipidemia (HLP) rats.

METHODSForty health SD rats were randomly divided into a normal control group (group A), a high fat forage feed group (group B) and a high fat forage feed treatment group (group C), a high fat forage + normal forage feed group (group D) and a high fat forage + normal forage feed treatment group (group E), eight rats in each group. EA was applied at "Fenglong" (ST 40) for the rats in group C and group E, once daily. After treatment of 30 days, blood lipid levels of rats, including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) in plasma were tested. Real time polymerase chain reaction (RT-PCR) and Western Blotting were applied to detect the gene expression changes of the contents of ATP-binding cassette transporter A1 (ABCA1), peroxisome proliferator-activated receptor alpha (PPARalpha), liver X receptor alpha (LXR-alpha) and retinoid X receptor alpha (RXR-alpha) in liver tissue of rats.

RESULTSCompared with group A, the contents of TC, LDL-C were significantly elevated in group B and group D (all P < 0.01); compared with group B, above indices were significantly decreased in group D (all P < 0.01). After the treatment of EA at "Fenglong"(ST 40), the contents of TC, LDL-C were significantly decreased (all P < 0.01), and the contents of TG, HDL-C did not change obviously (all P > 0.05). Compared with group A, the mRNA and protein contents of ABCA1, PPARalpha, LXR-alpha and RXR-alpha were decreased obviously in group B and group D (all P < 0.01). But compared with group B, the above indices were decreased in the group D. There were signficantly increasing in the protein content of ABCA1, PPARalpha, RXR-alpha and LXR-alpha mRNA after the treatment of EA (all P < 0.05).

CONCLUSIONEA at "Fenglong" (ST 40) has some therapeutic effect on decrease the content of TC, LDL-C in rats of hyperlipemia and improve the gene expression of ABCA1, PPARalpha, LXR-alpha and RXR-alpha mRNA so as to promote reverse cholesterol transport.
