Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

This article was aimed to study the impact on substance and energy metabolism by chemical split fractions of Mori Cortex among hypoglycemic diabetic mouse model, in order to explain the new hypothesis of the science connotation in nature and flavor of traditional Chinese medicine (TCM). Male Kunming mice were intraperitoneally injected with a large dose of streptozotocin (STZ) (170 mg·kg-1) to establish type 1 diabetes mellitus mouse model. Medication was given consecutively for four weeks. The enzyme-linked immunesorbent assay (ELISA) was used to detect glucosekinase (GCK), glycogen phosphorylase (PYGL), pyruvate dehydrogenase (PDH), α-ketoglutarate dehydrogenase (α-KGDHC), phosphoglycerate kinase (PGK), acetyl coenzyme A (acetyl-CoA), adenylate kinase (ADK), fumarase (FUM), cytochrome C reductase (CCR), cytochrome C oxidase (COX) and other indicators. Enzymatic detection was used to determine the content of ATP coenzyme (ATPs), the content and ratio of NAD and NADH, the content of myocardial cell Na+-K+ ATP enzyme, as well as the content of ATP and ADP. The results showed that in the model group, the expression of PYGL was increased; and the expressions of GCK and PDH were decreased. It prompted that the source of glucose increased and the expelling of glucose decreased. The glucose level was increased. The COX expression was reduced and the respiratory chain was blocked. It regulated oxidative phosphorylation and the substrate phosphorylation level. It upregulated the expression of CCR, ATPs, NAD+, PGK, α-KGDHC and ADK. However, the expression of FUM was decreased. The activity of Na+-K+ ATPase was decreased significantly. At last, the metabolic disorders appeared. Mori Cortex aqueous extracts and the chemical split fractions significantly increased the GCK and PDH level in substance metabolism among diabetic mice. The levels of PYGL, α-KGDHC, PGK and acetyl-CoA were decreased (P < 0.05, or P <0.01). Meanwhile, it increased ATP and FUM, myocardial cell Na+-K+ ATP enzyme, and COX level in the energy metabolism (P < 0.05). It decreased the level of NAD+, CCR and ATPs (P < 0.05, or P <0.01). It was concluded that both the aqueous extracts and chemical split fractions of Mori Cortex can effectively improve the substance and energy metabolism disorders of diabetic mouse model. This effect may be related to the cold nature of Mori Cortex.

Objective To observe the effect of acupuncture combined with moxibustion on heart rate variability (HRV) in patients with post-stroke depression. Methods 120 patients were divided into control group (n=60) and treatment group (n=60). Both groups took fluoxetine and accepted acupuncture therapy, and the treatment group accepted moxibustion additionally. Hamilton Depression Rating Scale-17 (HAMD-17) and the change of HRV were compared before and after treatment. Results The score of HAMD was lower, and the reductive ratio was higher in the treatment group than in the control group (P<0.05). The standard deviation of the mean of qualified normal sinus interval (SDNN) and standard deviation of sequential five-minute R-R interval means (SDANN) increased in both groups after treatment (P< 0.05), and were higher in the treatment group than in the control group (P<0.05). The root mean square differences of successive R-R intervals (RMSSD) and percentage of differences between adjacent normal sinus intervals greater than 50 ms (PNN50) decreased in both groups after treatment (P<0.05), and were lower in the treatment group than in the control group (P<0.05). The low frequency (LF), high frequency (HF) and LF/HF were higher in both groups after treatment (P<0.05), and were higher in the treatment group than in the control group (P< 0.05). Conclusion Acupuncture combined with moxibustion therapy can better adjust the function of autonomic nerve and reduce depression in patients with post-stroke depression.

Objective To observe the effect of needle warming moxibustion on cognitive dysfunction after stroke. Methods 76 stroke patients with cognitive dysfunction were randomly divided into treatment group (n=38) and control group (n=38). The treatment group received needle warming moxibustion and routine rehabilitation for 4 weeks, while the control group only received routine rehabilitation. They were assessed with Montreal Cognitive Assessment (MoCA) and activities of daily living (ADL) scale before and after treatment. Results The score of MoCA and ADL improved in both groups (P<0.05), and improved more in the treatment group than in the control group (P<0.05) after treatment. Conclusion Needle warming moxibustion could improve cognitive function in patients after stroke and activities of daily living.

OBJECTIVETo investigate the absorption mechanism of genistein self-microemulsifying system in rat intestines.

METHODThe concentrations of phenol red and genistein by in situ perfusion in rats were determined by UV and HPLC, respectively. The effects of drug concentrations, pH, various intestinal segments and P-glycoprotein (P-gp) inhibitor verapamil on the absorption had been studied.

RESULTThe absorption rate constant (Ka) of genistein had no significant difference at concentrations of 0.05-0.5 mg x mL(-1) and pH of 5.4-7.8 in perfusion. It was Ka of jejunum > ileum > duodenum > colon. The absorption of genistein in jejunum had significant difference (P < 0.05) compared with other parts of intestines. Ka was increased obviously when verapamil was coper-fused with genistein (P < 0. 05).

CONCLUSIONThe absorption of genistein self-microemulsifying system is a first order process with passive diffusion mechanism related to P-gp efflux. It can be absorbed at all segments of rat intestine, and the jejunum is the best absorption segment, pH had no special effect on the absorption of genistein self-microemulsifying system in rat intestine.

OBJECTIVETo investigate the effect of protecting liver of brevifolin and 8,9-single-epoxy brevifolin of Phyllanthus simplex.

METHODRats were administered with CCl4 (ip) or alcohol (ig) to establish acute or chronic liver injured model, respectively. ALT, AST and TBIL in serum were measured using colorimetric analysis to evaluate liver function. MDA content or SOD activity in serum and liver tissue was measured by thiobarbituric acid chromatometry and xanthine oxidase methods, respectively. The hemorheological parameters were observed.

RESULTBrevifolin and 8,9-single-epoxy brevifolin reduced the increase of ALT induced by CCl4, but they did not influence the increase of AST. And it could inhibit the pathologic increase of serum TBIL induced by alcohol. They could ameliorate the MDA increase or SOD decrease in serum and liver tissue in rats with liver injury, and decrease abnormal changed hemorheological parameters.

CONCLUSIONBrevifolin and 8,9-single-epoxy brevifolin show protective effective against acute and chronic liver injuries, and the mechanism is relevant to antagonizing the lipid peroxidation of free radical and improving the blood circulation.
