ABSTRACT
Sepsis is a critical illness with high morbidity and mortality. Anaerobic glycolysis plays an important role in the pathogenesis of sepsis. Pyruvate dehydrogenase complex (PDHC) serves as a key regulator during sepsis. With PDHC dephosphorylation and deacetylation, PDHC activity is upregulated, allowing pyruvate translocate to mitochondria in aerobic condition, preceding the production of acetyl-CoA to accelerate aerobic oxidation. Activation of PDHC improves the prognosis of sepsis through regulating the balance of lactate, release of inflammatory factors and energy metabolism. A variety of remedies can improve the prognosis of patients with sepsis by up-regulating the activity of PDHC, including dichloroacetate (DCA), vitamin B1, milrinone, tumor necrosis factor binding protein, and ciprofloxacin.This article reviews the role and the regulatory mechanism of PDHC and signal pathway in the sepsis metabolism, in order to innovate treatment for sepsis and multiple organ dysfunction.
ABSTRACT
Objective To explore the Diagnostic value of real-time three-dimensional ultrasound for urethral vaginal fistulas.Methods 5 patients with urethral vaginal fistulas were checked using real-time three-dimensional ul-trasound ,respectively by the abdomen and the sonographic appearance of pudendal observation of female urethral vagi -nal interval sagittal and transverse ,sagittal and transverse section by measuring the size of the fistula ,and voiding trial or colored liquid test injection from urethral to confirm .Results 5 cases of urethra,vagina ultrasonography can dis-play and urethral vaginal interval throughout the sagittal plane and different levels of cross section ,urethral vaginal in-terval by low echo-band-low echo constitute the sandwichsign in the fistula showed partial loss ,local band echo in-terruption,urethral and vaginal local fusion ,voiding trial or from the urethra into the colored liquid test further con-firmed the fistula,fistula and verify the existence of fistula after the operation the size .Conclusion Real time three-dimensional echocardiography by urethral vaginal interval in the axial and sagittal plane ultrasound at different levels , combining with the history and voiding trial or injected with colored liquid test from the urethra ,can provide a new i-dea for diagnosis of urethral vaginal fistula .
ABSTRACT
Objective: To study the contents of hyperoside in Semen Cuscutae,which grew in different host and different environment.Methods: Hyperoside was determined by HPLC.Results: The content of hyperoside is 0.28%-0.65% in the semen Cuscutae growing in different conditions in Shandong.The content is higher in semen of C.chinensis in Linyi,whose host is Scutellaria baicalensis Georgi.The content of hyperoside is lower in semen of C.australia which grew in Humulus scandens(lour.) Merr.The content has no obvious difference between C.chinensis and C.australis.Conclusions: The content of hyperoside in semen Cuscutae has relation with the hosts.The content increased with the seed mature degree.
ABSTRACT
To compare the effects of immune enhancement, anti-fatigue and anoxia tolerance on mice of four kinds of dodder seeds in Shandong Province.
ABSTRACT
Objective: To compare the effects of invigorating the kidney and strengthening yang on four kinds of Semen Custutae. Methods: Sexual organs of juvenile rat and shen yang deficiency rat were weighed to analyze its contents of SOD and MDA. Results: Alcohol extracts of four kinds of Semen Custutae have conspicuous effects on increasing weight of sexual organs. Water extracts of Semen Custutae have better effects on raising the contents of SOD and MDA and increasing weight of immune organs of shen yang deficiency rat. Conclusion: The effects of Cuscuta chinensis Lam. and C.australis R. Br. have better than that of C. japonica Choisy and C.lupuliformis Krockr in invigorating the kidney and strengthening yang.
ABSTRACT
Objective: To explore the differences among contents of quercetin and kaempferol in four kinds of Semen Cuscutae in Shandong province. Methods : Quercetin and kaempferol are determined by HPLC. Results : The contents of both quercetin and kaempferol are lower in four kinds of Semen Cuscutae. The former is within 0.0002% to 0.0502% and the latter varies from 0.0002% to 0.0205%, respectively. In seeds of Cuscuta chinensis Lam., C. japonica Choisy and C.lupuliformis Krocker, quercetin contents are much higher than kaempferol contents. while in seed of C. australis R.Br., by contrast, its quercetin content is lower than kaempferol. The contents of quercetin and kaempferol have close relation with both the variety and the hostplant. Conclusion : HPLC can be used for the quality evaluation of Semen Cuscutae.
