OBJECTIVETo observe the therapeutic effects of Berberine Capsule (BC) on patients with mild hyperlipidemia.
METHODSTotally 102 mild hyperlipemia patients were recruited. All patients were suggested to have proper diet and physical activity as basic therapy for 1 month of run-in period. Totally 97 patients completed it. Then they were randomly assigned to the berberine group (the treatment group, 49 cases) and the placebo group (the control group, 48 cases). Patients in the treatment group took BC 300 mg, while those in the control group took placebo 300 mg, thrice per day for 3 successive months. Then placebos and BC were interrupted for 2 months (as washout period). All subjects received only diet control and physical activity during washout period. After washout period, placebos and BC were re-administered to all patients in the same way for 3 months. Body mass index (BMI), fasting plasma glucose (FPG), TG, TC, LDL-C, and HDL-C were assessed after run-in period, washout period, at month 1, 2, 3 after the first therapy, at month 1, 2, 3 after second treatment, respectively.
RESULTSCompared with the end of run-in period, TG, TC, and LDL-C decreased, and HDL-C increased in the treatment group (P < 0.05) after first 3 months of treatment. Compared with 3 months after the first therapy, TG, TC, and LDL-C increased and HDL-C decreased in the treatment group after washout period (P < 0.05). Compared with the end of wash- out period, TC and LDL-C decreased in the treatment group at month 2 after second treatment (P < 0.05); TG, TC, and LDL-C decreased (P < 0.01, P < 0.05), and HDL-C increased (P < 0.05) at month 3 after second treatment. Compared with the control group at month 3 after second treatment, TG, TC, and LDL-C all decreased, and HDL-C increased in the treatment group (all P < 0.05).
CONCLUSIONBC was effective in improving blood lipid level in mild hyperlipidemia patients.

This paper was aim to optimize the purification technology of Rehmanniae Radix Praeparata extract with macroporous adsorption resin. With the content of manninotriose as index, the absorptive flow and time were investigated, as well as kinds, amount, flow of eluent. D-101 type macroporous adsorption resin was the best choice for the purification of manninotriose. The optimized parameters were as follows: the content of manninotriose at 161.16-53.72 mg x g(-1), absorption time 240 min, eluting solvent of purified water, volume flow at 1.5 BV x h(-1), and eluant volume at 6 BV. D-101 type macroporous adsorption resin could significantly increase the purity of Rehmanniae Radix Praeparata extract with the advantage of high absorption, remove most part of impurity, and the effect of semi-works production was better.

OBJECTIVETo observe the impact of bone morphogenetic protein-2 (rhBMP-2) on bone marrow stromal cells (BMSCs) osteogenesis in vitro and vascular endothelial growth factors (VEGF) expression in bone osteoporotic to prevent and treat the osteoporosis.
METHODSTwenty 6-month-old female SD rats weighted (300±20) g underwent bilateral ovariectomized. At 3 months after operation, dual-energy X-ray absorptiometry was used to measure bone mineral density of rats,the values were compared with preoperative to ensure the model successfully, and the osteoporosis rats' BMSCs were cultured by bone marrow adherent cultured and the BMSCs morphology was observed under a phase contrast microscope upside down. The osteoporosis rats' BMSCs at the 2nd generation (p2) were randomly divided into experimental and control groups and were added complete medium (containing rhBMP-2) and osteogenic induced liquid, respectively. Two weeks later, the formation of cell calcium nodules were detected by Alizarin red staining method,alkaline phosphatase activity was measured by enzyme standard instrument and the expression of VEGF was detected by RT-PCT method.
RESULTS(1)Whole body bone mineral density of rats before and after operation were (0.179±0.007), (0.158±0.006) g/cm2,there was statistically significant (t=4.180,P< 0.05). (2)Alizarin red staining at 2 weeks after osteogenesis induced by BMSCs (P2) in the experimental group had more strong dyeing effect than the control group obviously. (3)Alkaline phosphatase activity at 2 weeks after osteogenesis induced by BMSCs (P2) of the experimental group (15.62±1.27) ug/gprot was significantly higher than that of the control group (8.62±0.93) ug/gprot,there was statistically significant (t=7.709, P<0.01). (4)The expression of VEGF at 2 weeks after osteogenesis induced by BMSCs (P2) of the experimental group 3.723±0.143 was significantly higher than that of the control group 0.950±0.072, there was statistically significant (t=29.462, P<0.01).
CONCLUSIONRhBMP-2 can improve the in-vitro osteogenesis ability of ovary osteoporosis rat BMSCs, promote the VEGF expression of osteogenesis factor. Regulating the VEGF expression may be one of the mechanisms of BMP-2 to participate in bone metabolism.

The association of urinary cytokine concentration with the incidence of urinary tract infection in patients with diabetes mellitus was explored. Urinary interleakin-6 (IL-6) level in 156 female type 2 diabetes mellitus patients was tested and followed up for 6 months. The incidence of urinary tract infection between the top quartile of baseline urinary cytokine concentration with the bottom quartile was compared. The incidence of top quartile of urinary IL-6 concentration at baseline was significantly lower than that of bottom quartile ( 13.5% vs 37.8%, P<0.05 ). Abnormality of urinary IL-6 concentration may be involved in the mechanism leading to higher prevalence of urinary tract infection in patients with diabetes mellitus.

Objective To observe the B-scan ultrasonic characteristics of the posterior vitreous detachment (PVD) and the relationship between the PVD and retina. Design Retrospective case series. Participants 991 cases (1107 eyes) with PVD. Methods The results of B-scan ultrasonography were retrospectively in PVD patients and according to the adhesion between the posterior vitreous cortex (PVC) and eyeball wall, complete PVD and incomplete PVD were divided. Main Outcome Measures The ratio of types and characteristics of PVD. Results 710 eyes(64.1%)were diagnosed as complete PVD, in which 69 eyes(17.3%)accompanied with peripheral ruptured detachment of retina, and 16 eyes(23.0%)PVC adhered with lid of peripheral retina hole. 397 eyes(35.9%)were diagnosed as incomplete PVD, in which 159 eyes(40.0%)as partly PVD, and 76 eyes(47.7%)concomitanted with PVC proliferation and vitreous incompletely splitting. 121 eyes(30.5%)PVC were adhered with the macula, and 117 eye(29.5%)with the optic disc. Conclusions Ultrasonography can be applied to diagnose PVD precisely,which can provide credible morphologic evidence for the clinic.
