OBJECTIVETo observe the clinical therapeutic effect of Nuzhen Yunyu Decoction (NYD, a Chinese recipe for nourishing blood and reinforcing Shen) and its influence on the hemodynamic parameters in ovarian and uterine arteries.
METHODSSixty-eight patients were randomly divided into two groups at the ratio of 2:1, 45 in the TCM group treated with Chinese medicine and 23 in the control group treated with clomiphene citrate. Menstrual cycle were taken as the indexes for clinical observation; basal body temperature, cervical mucus, vaginal exfoliative cells, serum hormones and B ultrasonic examination were taken as the indexes for ovulation and pregnancy assessment. The hemodynamic parameters of uterus and ovary were determined by using color Doppler ultrasonography, and the growth of follicles and ovulation, thickness of uterine endometrium were also monitored continuously.
RESULTSResults of 3 cycles treatment and 1 year follow-up study showed that the ovulation promoting rate, pregnancy rate and abortion rate in the two groups were similar, but the treated group showed better effects than that of control group, in such aspects as regulating menstruation, promoting growth and development of follicle, strengthening endometrium, improving blood supply and circulation of uterine and ovary (P < 0.05, P < 0.01).
CONCLUSIONNYD has the effects of ovulation promotion and holistic regulation of reproductive system.

To evaluate the regulating effect of Buyang Huanwu decoction and its simple prescription (Naojian tablet) on CDK4/Cyclin D1 expression in hippocampus tissues of rats with cerebral ischemia, SD rats were divided into the sham-operation group, the model group, the Buyang Huanwu decoction group (ig, 3.15 g · kg⁻¹) and the simple prescription group (ig, 2.41 g · kg⁻¹). Each group was further divided into five subgroups based on time points after the administration, i. e. 1 d, 3 d, 7 d, 14 d and 28 d, respectively. CDK4/Cyclin D1 expressions of the group at different time points were examined by using immunohistochemistry and real-time qPCR. According to the results, the cerebral ischemia model group showed higher CDK4/Cyclin D1 expression than the sham-operation groups (P < 0.05), suggesting that the cell cycle signal pathway would be activated by the cerebral ischemic injury. Both Buyang Huanwu decoction and simple prescription groups showed significantly lower cyclin expression than the model group at 3 d, 7 d, 14 d, 28 d (P < 0.05), indicating both Buyang Huanwu decoction and its simple prescription could play the neuroprotective effect through the cell cycle signal pathway.

OBJECTIVETo investigate a new method to construct tissue-engineering bone that will be applicable clinically.
METHODSThe cultured 5th generation rabbit bone marrow stroma osteoblasts (MSO) was dissolved in 3% sodium alginate solution (the final concentration of sodium alginate in the solution being 1%, and MSO, 5x10(6)/L), and then inoculated into prepared true bone ceramic (TBC) and gelatinized the bone by dribbling with calcium gluconate. The standard bone defect models were made in 48 adult New Zealand rabbit's both radius. Among the 48 rabbits, 24 were in Groups A and B, in which the left radius was implanted with gelatinized MSO-TBC (Group A) and right radius implanted with autograft-bone (Group B); and the other 24 were in control group whose left radius was implanted with non-gelatinized MSO-TBC (Group C) and right radius implanted with gelatinized TBC (Group D). Outcomes of the implanted bones were assessed by radiology, pathological histology, osteogenetic quantitative analysis, and biomechanics at 2, 4, 8, 12 weeks postoperatively.
RESULTSIn Groups A and B, a satisfactory bone reparation and bony union was noted within 12 weeks. In Groups C and D, bone reparation was not satisfied compared with Group A in terms of ostogenetic quantity and biomechanics.
CONCLUSIONSGelatinized MSO-TBC is an ideal artificial active bone that overcomes TBC shortcomings of fragileness and smooth surface that is not eligible for seed cell's adhesion. It is promising to put into clinical use extensively.

OBJECTIVETo investigate the effects of hyperbaric oxygen (HBO) treatment on the activation of astrocytes and the expression of glia-derived neurotrophic factor (GDNF) and nerve growth factor (NGF) in the brain after traumatic brain injury (TBI).
METHODS54 male SD rats were randomly divided into three groups (n = 18): sham-operated, TBI and HBO treatment groups. TBI was induced with Feeney's method, bone window was opened without strike on the brain tissue in the sham-operated group. HBO group rats received HBO treatment for 60 min in the hyperbaric chamber containing O2 100% at 3 ATA. When neurological functions were measured 48 h after TBI, rats were decapitated, the brain water content of 18 rats was measured, 18 brains were sliced for the morphological observation after Nissl staining and for the immunohistochemistry staining of astrocyte markers glial fibrillary acidic protein (GFAP), vimentin and S100, and the other 18 brains of injured side were used for Western blot analysis of GDNF and NGF.
RESULTSHBO treatment reduced the neurological deficit, brain water content and hippocampal neuronal loss. In the observed cortex and hippocampal area astrocytes were activated, the cell number of positive expression of astrocyte markers GFAP, vimentin and S100 was increased, and the expression of GDNF and NGF was elevated after TBI. However, these indices were all enhanced further after the HBO treatment.
CONCLUSIONIt is suggested that HBO may be an effective therapy for TBI and upregulation of the expression of GDNF and NGF may underly the effect of HBO.
