Objective To explore the action mechanism of Yiqi Huayu Formula for postpartum subinvolution of uterus. Methods Fifty female SD rats were selected model with postpartum subinvolution of uterus was made by injecting escherichia coli in vagina. Rats were randomly divided into 5 groups according to pregnancy time:blank group, model group, Xinshenghua group, and Yiqi Huayu high and low dose groups. Blank group and model group received gavage with water;Yiqi Huayu low and high dose groups received gavage with Yiqi Huayu Formula;Xinshenghua group received gavage with Xinshenghua Granule, once a day for 7 days. Uterine endometrial morphology was observed by HE staining. The contents of NO and NOS were respectively detected by Nitrate reductase method. Results Uterus submucosal hyperemia, bleeding, and endometrial discontinuity with the infiltration of inflammatory cells of rats in the model group suggested that the models were successfully established. Compared with blank group, the contents of NO and NOS in model group were higher significantly. Compared with model group, the contents of NO and NOS significantly decreased in both Xinshenghua group and Yiqi Huayu high and low groups (P<0.01, P<0.01). Compared with Xinshenghua group, Yiqi Huayu high dose group was lower (P<0.05). Conclusion Yiqi Huayu Formula could promote reconstruction and repair of the endometrium by reducing the contents of NO and NOS and inhibiting abnormal uterine spiral arteries relaxation.

Objective To explore the feasibility of enhanced green fluorescent protein (EGFP) transfection into the joint synovial tissues of rheumatoid arthritis (RA) rats by ultrasound-mediated microbubble destruction.Methods Twenty-eight normal rats were established the RA rat model,four rats were control group,twenty-four rats were categorized into four experimental groups:EGFP,ultrasound +EGFP,microbubbles + EGFP,and ultrasound + microbubbles + EGFP.The last group was irradiated with ultrasound for 10 min after the mixture consisting of 300 μl Sono Vue and 10 μg EGFP was injected into the joint cavity.The rats were sacrificed after 3 days and the joint synovial tissues were collected for EGFP observation under fluorescence microscopy and quantitative analysis by real-time polymerase chain reaction (RT-PCR).Results Comparing with control group,EGFP expression was observed in the rat joint synovial tissues from all groups.However,a strong EGFP expression was observed in the ultrasound + microbubbles +EGFP group.EGFP expression had no statistically significant difference (the P values were 0.89,0.93,and 0.82,respectively,P > 0.05) in the EGFP,ultrasound + EGFP and microbubbles + EGFP groups.However,EGFP expression in the EGFP,ultrasound + EGFP,microbubbles + EGFP groups significantly differed (all P values were <0.01) from that in the ultrasound + microbubbles + EGFP group.Conclusions Ultrasound-mediated microbubble destruction can improve EGFP transfection efficiency into the joint synovial tissues of RA rats.

Objective To observe the bioeffects on the normal rats synovial with diagnostic ultrasound combined with different doses contrast medium. Methods Twenty normal cleaning level Wister rats were divided into 5 groups (each with 4 rats and 8 knees): ultrasound+100 μl contrast medium, ultrasound+200 μl contrast medium, ultrasound+300 μl contrast medium, ultrasound+500 μl contrast medium, a simple ultrasound irradiation (control group). Each group was irradiated with diagnostic ultrasound for 10 min. Rats were sacrificed after 1 week and joints synovial tissues were observed with pathological HE staining. Results In group ultrasound+100 μl contrast medium, ultrasound+200 μl contrast medium, ultrasound+300 μl contrast medium and control group, no significant damage in synovial tissues was found. In group ultrasound+500 μl contrast medium, synovial cells swelling, showing round, oval or polygonal, synovial tissues hyperplasia, arranged disorder, capillary proliferation, some muscle fiber structure dissolved fracture, inflammatory cell infiltration in the surrounding tissue were found. Conclusion Ultrasound combined with contrast medium can significantly enhance the bioeffects of synovial tissues, and the more the contrast medium doses, the more serious injury occurs in synovial tissues.

AIM To investigate the effect of Icarrin on penile erection and cyclic GMP levels in rabbit corpus cavernosum(RCC). METHODS Effects of various concentration of Icariin on cGMP level in RCC were measured by 125 I radioimmunoassay procedure with Sildenafil and papaverine as the positive controls RESULTS In the presence of SNP, Icariin increased cGMP concentration in rabbit corpus cavernosum in a dose dependent manner ( P

Objective To investigate the association of body mass index (BMI),sex and age with blood pressure in non-physical labor population from Beijing area.Methods 14 237 subjects (67.06% male) ranged from 18.0-93.0 years (mean (SD):49.8(10.2)) wero recruited in the health examination in Beijing hospital. Statistical analysis wag performed using SPSS 12.0 software.Results The average BMI wag 22.30 ks/m~2 (SD: 3.08).Systolic blood pressure and diastolic blood pressure increaged with the increasing of BMI.The prevalence of hypertension in males <60.0 years wag considerably higher than that of female (24.28% and 13.77% for male and females, respectively, P=0.000).However,there were no significant statistical differences for the pmvalence between male and female older than 60.0 years (P=0.268).Multiple logistic regression showed that in males,using the group with BMI<18.0 kg/m~2 as reference group,in the groups of BMI 18.0-23.9,24.0-27.9,≥28.0 kg/m~2, OR wag 1.709 (95% CI:0.920-3.173),3.154(1.703-5.839),5.125 (95%CI:2.805-9.696),respeetively.In females.OR for hypertension in the groups of BMI 18.0-23.9,24.0-27.9,≥28.0 kg/m~2,OR was 1.988(95%CI:1.033-3.824),5.703(2.962-10.982),14.358(95%CI:7.334-28.106),respectively.Conclusions BMI is associated with hypertension.Prevention and eontrol of the risk factom of hypertension e.g.overweight and obesity is an important public health issue in China.

Objective To construct a short hairpin RNA (shRNA) adenovirus vector targeting Aktl (protein kinase B1, PKBI/Aktl) and cyclooxygenase-2 (COX-2) and study its effects on the invasion and metastasis of SGC-7901 human gastric adenocarcinoma cells. Methods Aktl and COX-2 shRNA expression frames were subcloned to pGSadeno adenovirus vector by homologous recombination technology to construct pGSadeno-Aktl+COX-2 (rAdS-A+C) vector. After screening and amplification, the recombinant adenovirus vector was digested with PacI and transfected into SGC-7901 cells, the titer and transfection efficiency were detected by fluorescent microscopy. Aktl and COX-2 mRNA and protein expression was identified by real-time PCR and Western blot. MMP-2 and MMP-9 contents in control group SGC-7901、rAd5-HK and treatment group rAdS-A+C were detected by ELISA assay and transwell assay analyzed cell invasion and metastasis ability. Results Adenovirus vector rAdS-A+C was successfully constructed and it dramatically down-regulated Aktl and COX-2 mRNA and protein expression in SGC-7901 gastric cancer cells. MMP-2 and MMP-9 contents in treatment group rAd5-A+C were respectively (39.7± 1.7) ng/ml, (31.3±3.6) ng/ml, and they were lower than those in control group SGC-7901 (278.4± 15.5) ng/ml, (225.4±15.1) ng/ml and rAd5-HK (275.5±2.1) ng/ml, (226.0±23.3) ng/ml (P= 0.01, P=0.021). Transwell assay showed treatment group rAd5-A+C significantly inhibited the invasion and metastasis of SGC-7901 gastric adenocacinoma cells. Conclusions Adenovirus-mediated targeting Aktl and COX-2 shRNA can inhibit the invasion and metastasis of SGC-7901 human gastric adenocarcinoma cells.
