Objective:To discuss the clinical efficacy of Shenghua Decoction combined with conventional western medicine therapy in treatment of polycystic ovarian syndrome with blood-insufficiency congealing-cold and blood-stasis syndrome. Methods:A total of 140 polycystic ovarian syndrome patients with blood-insufficiency congealing-cold and blood-stasis syndrome were selected from January 2018 to December 2019 in our hospitals, and were divided into observation group and control group according to the random indicator method, 70 cases in each group. The control group received ethinylestradiol and cyproterone acetate tablets treatment, and Shenghua Decoction was added based on the control group’s treatment in the observation group. Changes in the TCM syndrome score, modified Ferriman-Gallway (mF-G) of hirsutism, Rosenfield of acne, Testosterone (T), Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) levels detected by ELISA of two groups were observed. The adverse events were recorded and the clinical efficacy was evaluated. Results:The effective rate of the observation group was 88.6% (62/70), which was significantly higher than control group of 60.0% (42/70) ( χ2=14.957, P<0.001). After treatment, mF-G, Rosenfield and TCM Syndrome Scores in the observation group were significantly lower than those in the control group ( t=6.524, 3.111, 2.196, P<0.01 or P<0.05). After treatment, the levels of FSH [(5.16 ± 1.76) IU/L vs. (7.19 ± 1.06) IU/L, t=2.530], LH [(6.12 ± 1.88) IU/L vs. (8.03 ± 1.78) IU/L, t=2.403], T [(1.34 ± 0.32) μg/L vs. (1.80 ± 0.36) μg/L, t=7.080] in the observation group were significantly lower than those in the control group ( P<0.05 or P<0.01) Conclusion:The Shenghua Decoction showed beneficial effect for the patients with polycystic ovarian syndrome with blood-insufficiency congealing-cold and blood-stasis syndrome.

Objective To develop a multiple PCR-based reverse line blot hydrization assay (mPCR-RLB)to simutaneously detect several STD pathogens:Neisserria gonorrhoeae,Chlamydia trachomatis,Ureaplasma urealyticum,U.parvum,Mycoplasma genitalium,M,hominis and Trichomonas vaginalis.Methods Seven pairs of biotin-labelled primer were designed and synthesized to target the 16S rRNA-23S rRNA intergenic spacer regions of Neisserria gonorrhoeae,Chlamydia trachomatis,Mycoplasma,and repetitive DNA sequence of Trichomonas to identify and subtype thesc pathogens.DNA was extracted from the referrence strains of seven pathogens and used as templates.mPCR was performed to simutaneously amplify the target regions of these pathogens.Then,the biotin-labelled amplicons were hybridized with membrane-bound specific oligonucleotide probes followed by the detection of bound amplicons with chemiluminescence assay.Serially diluted plasmids containing the target genes of pathogens were amplified with this method to detect its sensitivity.Two-hundred and eleven specimens,including 104 male urethral swabs and 107 female cervical swabs,were collected from the STD clinic of Wuhan First Hospital;mPCR-RLB and single-primer PCR were performed.For specimens with inconsistent results,nested PCR was performed to confirm the results.Results The assay sensitively and specifically identified referrence strains of the tested pathogens.The detection limit of mPCR-RLB was 100 copies for all the pathogens.Of the 211 clinical specimens,2.8%(6/21)were negative for single-primer PCR,but positive for mPCR-RLB,and nested-PCR results were consistent with those of mPCR-RLB.Conclusion mPCR-RLB is a sensitive,specific and rapid method for the detection of STD pathogens from clinical specimens.

BACKGROUND: Dysfunction of endothelial cells is independently associated with coronary atherosclerotic heart disease. Correlation of dysfunction of endothelial cells to restenosis after stent implantation is not yet clearly determined.OBJECTIVE: To evaluate the correlation of vascular endothelial dysfunction to restenosis after stent implantation. DESIGN, TIME AND SETTING: A case control study was performed at the Department of Cardiology and Department of Heart Ultrasound, Sichuan People's Hospital from March 2005 to January 2007.PARTICIPANTS: After review, coronary angiography showed that 11 patients who occurred restenosis at the lesion region after stent implantation were included in a restenosis group, and an additional 15 patients who did not develop in-stent restenosis were included in a control group. Patients in the following conditions were excluded: over 70 years old, histories of long-term smoking, diabetes mellitus, multivessel disease, long coronary lesion and chronic total occlusion, heart failure (Killip's class Ⅲ or above), severe hepatic and/or renal insufficiency.METHODS: High-resolution ultrasound was used to assess the percentage of flow-mediated dilatation of brachial artery. Differences in endothelial function were compared between both groups.MAIN OUTCOME MEASURES: Ultrasound parameter of the brachial artery in both groups; Partial correlation analysis on control variable including sex, age, blood lipid level, diseased region and stent type.RESULTS: No significant difference was found in basic diameter of brachial artery in both groups. During reactive hyperemia, inner diameter and its absolute variation of brachial artery were smaller in the restenosis group than in the control group (P<0.01). The percentage of brachial artery flow-mediated dilatation was lower in the restenosis group compared with the control group (P=0.013). The partial correlation coefficient between the percentage of flow-mediated dilatation of brachial artery and in-stent restenosis was 0.47 (P=0.04).CONCLUSION: The endothelial dysfunction significantly decreases in patients with restenosis compared with controls following stent implantation. There is a correlation between endothelial dysfunction and restenosis.

To study the molecular mechanism of salt stress response of peanut small GTP binding protein gene AhRabG3f, a 1 914 bp promoter fragment upstream of the start codon of AhRabG3f gene (3f-P) from peanut was cloned. Subsequently, five truncated fragments (3f-P1-3f-P5) with lengths of 1 729, 1 379, 666, 510 and 179 bp were obtained through deletion at the 5' end, respectively. Plant expression vectors where these six promoter fragments were fused with the gus gene were constructed and transformed into tobacco by Agrobacterium-mediated method, respectively. GUS expression in transgenic tobacco and activity analysis were conducted. The gus gene expression can be detected in the transgenic tobacco harboring each promoter segment, among which the driving activity of the full-length promoter 3f-P was the weakest, while the driving activity of the promoter segment 3f-P3 was the strongest. Upon exposure of the transgenic tobacco to salt stress, the GUS activity driven by 3f-P, 3f-P1, 3f-P2 and 3f-P3 was 3.3, 1.2, 1.9 and 1.2 times compared to that of the transgenic plants without salt treatment. This suggests that the AhRabG3f promoter was salt-inducible and there might be positive regulatory elements between 3f-P and 3f-P3 in response to salt stress. The results of GUS activity driven by promoter fragments after salt treatment showed that elements included MYB and GT1 between 1 930 bp and 1 745 bp. Moreover, a TC-rich repeat between 682 bp and 526 bp might be positive cis-elements responsible for salt stress, and an MYC element between 1 395 bp and 682 bp might be a negative cis-element responsible for salt stress. This study may facilitate using the induced promoter to regulate the salt resistance of peanut.
