OBJECTIVETo explore the significance of pelvic hemodynamics as an index in evaluating efficacy of TCM treatment for chronic pelvic inflammation (CPI).

METHODSSixty patients with CPI received treatment with Penyanping, a self-formulated TCM recipe, for 30 days, and the changes of pelvic hemodynamic indexes in them were measured before and after treatment within the 3 - 7 days after menstruation using color Doppler.

RESULTSImprovement of pelvic hemodynamics indexes were shown after treatment in ovarian left arteriopalmus index, bilateral resistance index, maximal speed of left arterial blood flow and score of time-velocity, as compared with those before treatment, the difference was significant respectively (P < 0.05).

CONCLUSIONPelvic hemodynamic indexes could be taken as one of the objective parameters for evaluating efficacy of TCM treatment of CPI according to principle of activating blood circulation to remove stasis, clearing heat and detoxifying.

Acute myeloid leukemia (AML),the most common disease in acute leukemia,is a highly heterogeneous invasive hematological disease.The t(8;21)(q22;q22) translocation is the most common chromosomal translocation in AML,generating AML1-ETO fusion gene and encoding AML1-ETO fusion protein.This article summarizes the two-hit hypothesis in AML occurrence,the pathogenesis of t(8;21)AML,all features involved in t(8;21)AML,and the function of the components in AML1-ETO fusion protein,providing important basic information for the treatment and prognosis of t(8;21)AML.Meanwhile,this article also summarizes the progress of next generation sequencing technique in leukemia,providing a new technique for the accurate therapy of (8;21)AML.

AIM To study the dynamic changes of color and five constituents during processing of Gardeniae Fructus.METHODS Camera and Adobe Photoshop software were applied to collecting images and obtaining chromatic values (L,a,b) of processed products,respectively.HPLC was adopted in the content determination of genipin-1-β-D-gentiobioside,geniposide,crocin-Ⅰ,crocin-Ⅱ,crocin-Ⅲ.Then the correlation between color and constituent contents was investigated by linear regression and partial least squares method.RESULTS With the process of processing,the chromatic values of epicarp and seed pellets expelled showed decreasing trends,especially for that of the former.On the whole,the contents of geniposide,crocin-Ⅰ and crocin-Ⅱ were decreased,while those of genipin-1-β-D-gentiobioside and crocin-Ⅲ were first increased and then decreased.The chromatic values of epicarp and seed pellets expelled showed significant correlations with crocin-Ⅰ content.CONCLUSION Color and crocin-Ⅰ can be considered as control index and monitoring index during processing of Gardeniae Fructus,respectively.

Pseudomonas sp. M18 is one of plant growth-promoting rhizobacteria capable of producing two kinds of anti-fungal agents: phenazine-1-carboxilic acid (PCA) and pyoluteorin (Plt). The pqsR gene, which encodes a LysR family member PqsR, was amplified from chromosomal genome of strain M18. Using the homologous recombination technique, a chromosomal pqsR inactivated mutant strain M18PRG was constructed in Pseudomonas sp. M18. To study the effect of pqsR gene on Plt biosynthesis, the dynamic curves of Plt production by strains M18 and M18PRG was measured in KMB media. As a result, Plt production of the pqsR mutant was three to four folds higher than that of its parent strain M18. The Plt production was restored to the wild-type level when strain M18PRG was complemented with pqsR gene in trans. The regulation of pqsR gene on Plt production was further confirmed by the pltA′-′lacZ translational fusion analysis. These results indicate that pqsR gene negatively controls the Plt biosynthesis. Additionally, by analyzing the growth curves of wild type strain M18 and pqsR mutant, wecan readily find that PqsR has a negative influence on cell growth. It was also shown that the production of red pigments in strain M18 required the expression of pqsR gene. In conclusion, the data presented in this study clearly demonstrate that PqsR acts as a global regulator involved in many physiological activities in Pseudomonas sp. M18.

OBJECTIVETo investigate the hypocholesterolemic activity of red yeast rice (RYR) and its underlying mechanism.

METHODSThree groups of hamsters were fed either the control diet or one of the two experimental diets containing by weight 0.1% RYR (0.1RYR) or 0.3% RYR (0.3RYR). Blood (0.5 mL) was collected from the retro-orbital sinus into a heparinized capillary tube at the end of week 0, 3, and 6. Plasma lipoproteins were measured using enzymatic kits, while fecal neutral and acidic sterols were quantified using a gas-liquid chromatography.

RESULTSPlasma total cholesterol was reduced by 12% in 0.1RYR group and by 18% in 0.3RYR group compared with the control value. Similarly, plasma triacylglycerol was decreased by 11% in 0.1RYR group and by 24% in 0.3RYR group. Western blotting analysis demonstrated that RYR had no effect on sterol regulatory element binding protein 2, liver X receptor, 3-hydroxy-3-methylglutary-CoA reductase, LDL receptor, and cholesterol-7alpha-hydroxylase. HPLC analysis confirmed that RYR contained 0.88% monacolin K. It was recently found that RYR supplementation increased excretion of fecal acidic sterols by 3-4 folds compared with the control value.

CONCLUSIONHypocholesterolemic activity of RYR is mediated at least partially by enhancement of acidic sterol excretion.

Cistanche Herba is one of precious traditional Chinese medicine, which original wild plant resources dropped sharply in recent years. It is urgent to make sustainable utilization. The genus of Cistanche is a total parasitic plant, its physiological ecology and nutrition transfer are very particular. The status of the studies on habitat characteristics, parasitic mechanism and nutrient transport of Cistanche was reviewed, prospect was also given. It can provide reference for the further basic and applied studies on the nutrition transfer, germplasm quality and agriculture practice.

Objective To propose the concept of separate interhemispheric subdural effusion, and further study the pathogenesis, diagnosis, treatment and prevention of the disease. Methods 544patients with head injury who were treated by decompressive craniotomy with large bone flap removal (treatment group) or decompressive craniotomy without large bone flap removal (control group) were retrospectively analyzed for understanding the incidence of separate interhemispheric subdural effusion and studying the pathogenesis and risk factors of the disease. Results CT examination showed separate interhemispheric subdural effusion occurred in 38 cases, including 14 of unilateral craniotomy and 24 of bilateral craniotomy, in the treatment group, and 8 cases, including 2 of unilateral craniotomy with disposable bone flap and 6 of bilateral craniotomy with disposable flap, in the control group. The difference in the incidence of separate interhemispheric subdural effusion was significant statistically between treatment and control groups (X2=9.758,P=0.002), but not significant between unilateral and bilateral craniotomies in the two groups (X2=0.053,P=0.818). Conclusions Separate interhemispheric subdural effusion is one type of subdural effusion, and related to brain tissue shift after large bone flap craniotomy. It is one of the most common complications after the craniotomy. It can be diagnosed conveniently by the means of imaging. Early diagnosis and treatment will be beneficial for good prognosis, and to reduce the size of the bone window and to avoid brain tissue shift after operation are the best preventive measures.
