6.24 mmol/L) and sixty healthy persons in the health center of our hospital were investigated as hyperhpidemia group (Hyperlipidemias) and control group (Controls) respectively.Hyperlipidemias were given simvastatin 20 mg?d~(-1) for twelve weeks (Statins).Blood samples of ulnar vein were extracted from Statins at the end of twelve weeks as well as Controls and Hyperhpidemias at the beginning of the experiment. Blood serum,plasma and mononuclearcell were extracted and stored at a refrigerator of-80℃.The level of plasma angiotensinⅡwas detected by the method of radioimmunity.While the expression of RANTES mRNA and protein on mononuclearcell were assessed by real time reverse transcription polymerse chain reaction and Western blot respectively.Results①The plasma angiotensinⅡof Hyperlipidemias was higher than that of Controls [(92.13?22.03) vs (50.85?12.12),P

OBJECTIVETo investigate the effect of 6-gingerol, the main active component of ginger, on hair shaft elongation in vitro and hair growth in vivo.
METHODSFirstly, Hair follicles were co-cultured with 3 different concentration of 6-gingerol for 5 days and hair elongation in three groups was measured. Secondly, The proliferative effect of 6-gingerol on DPCs was measured using MTT assay. Thirdly, the expression of Bcl-2 and Bax in DPCs were measured using Western blotting. In vivo study, the influence of 6-gingerol on hair growth in C57BL/6 rats was measured through topical application of 6-gingerol on the dorsal skin of each animal.
RESULTSThe length of hair shaft in 20 microg/ml 6-Gingerol group (0.50 +/- 0.08 mm) is less than 0 microg/ml (0.66 +/- 0.19) mm and 10 microg/ml (0.64 +/- 0.03) mm 6-Gingerol group (P < 0.05). In cell culture, compared to 0 microg/ml and 5 microg/ml 6-Gingerol, 10 microg/ml 6-Gingerol can significantly inhibited the proliferation of DPCs (P < 0.05). Along with the growth inhibition of DPCs by 6-gingerol, the Bax/Bcl-2 ratio increased obviously. In vivo study, the hair length and density decreased a lot after using 1 mg/ml 6-gingerol.
CONCLUSIONS6-Gingerol can suppress human hair shaft elongation because it has pro-apoptotic effects on DPCs via increasing Bax/Bcl-2 ratio. It might inhibit hair growth by prolonging the telogen stage in vivo.

OBJECTIVETo study the effects of JTS, Traditional Chinese Medicine caps. treating cerebral ischemia on metabolism and antioxidant system in cerebral ischemia rat.
METHODSI.m. dexamethasone and ligating common carotid artery, the model of cerebral ischemia rats was established to investigate the effects of JTS caps. and its mechanisms through detecting substance metabolism, energy metabolism and antioxidant system.
RESULTSJTS caps. (1.78 - 3.56 g/kg) could upgrade glucose (Glu), total amino acids (T-AA), ATP, Na(+)-K(+) -ATPase, superoxide dismutase (SOD) and catalase (CAT) of brain tissue and degrade lactic acid (LD), malondialdehyde (MDA) and water content of brain tissue in cerebral ischemia rat (P < 0.05, 0.01). JTS caps. (3.56 g/kg) could also depress extenuation of rat's body weight.
CONCLUSIONJTS caps. has some protections against the cerebral ischemia in rats, and one of the mechanisms may be improving the metabolism and antioxidant system.

OBJECTIVETo explore the mechanism of shikonin for inducing the apoptosis of human promyelocytic leukemia cell HL-60.
METHODSThe effects of shikonin on the HL-60 cell proliferation were detected using MTT. The apoptosis rate was analyzed by Annexin-V/PI double staining. The expression level of the bcl-2 gene was detected using semi-quantitative reverse transcriptase PCR (RT-PCR), thus analyzing the correlation between the bcl-2 expression level and the apoptosis of HL-60.
RESULTSShikonin could inhibit the proliferation of HL-60 cells with the concentration range of 1-8 microg/mL in a time- and concentration-dependent manner. Two microg/mL shikonin could induce the apoptosis of HL-60 cells in a time-dependent manner. The expression level of bcl-2 was obviously down-regulated at 2 microg/mL shikonin.
CONCLUSIONSShikonin could induce the apoptosis of HL-60 cells. Its mechanism was correlated with down-regulation of the expression level of bcl-2.

OBJECTIVETo investigate the effect of embryonic dermal signal on the hair-inductive capacity of neonatal mice dermal cells which have been amplified in vitro.
METHODSEmbryonic mice dermal cells of embryonic day 14 were added to a chamber on the back of nude mice with neonatal mice dermal cells which had been amplified in vitro for 3 days and freshly isolated neonatal mice epidermal cells. The hair regeneration was compared between the groups with or without embryonic mice dermal cells. Meanwhile, chambers with following cells respectively were constructed as controls: embryonic mice dermal cells + neonatal mice epidermal cells; freshly isolated neonatal mice dermal cells + neonatal mice epidermal cells; amplified neonatal mice dermal cells only; embryonic mice dermal cells only; freshly isolated neonatal mice dermal cells only; neonatal mice epidermal cells only.
RESULTSThe number of regenerated hairs with the aid of embryonic mice dermal cells (207 +/- 15. 948) was significantly higher than that (67 +/- 8.963) in the group without embryonic mice dermal cells (n = 3, t = 7.653, P = 0.002).
CONCLUSIONEmbryonic dermal signal can enhance the hair-inductive capacity of neonatal mice dermal cells which have been amplified in vitro.

Objective To investigate the features of chronic prostatitis during puberty(CPP)and the effects of pelvic floor biofeedback therapy.Methods Totally,25 CPP children (mean age,16 years) and 15 children (mean age,16 years) with normal lower urinary tract as controls were included.In CPP group,NIH-CPSI scores were evaluated,expressed prostatic secretions (EPS) were examined,and bacterial culture was done;and CPP patients were categorized based on the definitions of NIH types.In both groups, urodynamic examination was performed,including evaluation of uroflow curve,maximum flow rate (Q_(max)), post-voiding residual urine (PVR),detrusor-sphincter dyssynergia (DSD),maximum detrusor pressure (P_(det,max))and maximum urethral closure pressure (MUCP).CPP patients underwent biofeedback therapy, and 10 weeks later the effects were assessed.Results In CPP group,NIH typing showedⅡ,ⅢA andⅢB in 1,3 and 21 cases,respectively.Before treatment in CPP and control groups,the incidence of staccato voiding (20 cases vs 1 case),DSD (22 cases vs 1 case),Q_(max)(10.7?3.7 vs 15.0?4.3ml/s),PVR (7.7?4.1vs 3.2?2.6ml),P_(det,max)(115.1?33.6vs 76.8?16.6cm H_2O)and MUCP(176.5?45.7 vs 86.2?28.5cm H_2O)all showed significant differences between the 2 groups(P<0.05).In CPP group,the differences in pain(4.6?2.2 vs 2.1?1.6),urination (7.9?2.0vs 2.2?1.7),life impact (9.4?2.2vs 2.6?2.1)and total scores(22.0?5.2vs 7.0?4.2) of NIH-CPSI and Q_(max)(10.7?3.7 vs 14.9?5.6) between pre-and post-biofeedback were significant (P<0.05).Conclusions The main type of CPP is categoryⅢB.The primary symptom is voiding disorder,which leads to greater psychological stress in patients.Children with CPP have pelvic floor dysfunctions and multiple abnormal urodynamic param- eters.The short-term effect of biofeedback strategies for CPP is satisfactory.

Objective To estimate the difference of PS、CBV/CBF in the evaluation pf angiogenesis and growth behavior of the C6 glioma.Methods Sixty adult Wistar rats were divided into 3 groups randomly.CT perfusion were performed at the time of 5,13,20 d after the rats were inoculated C6 glioma cells.Permeability surface(PS),cerebral blood volume(CBV),cerebral blood flow(CBF)of different part of the tumor(central part,peripheral part,adjacent part and contralateral normal parenchyma)were measured at different time.Results At the central parts of the lesions,there were obvious difference between different time of tumor growth among PS[(3.94?0.15),(8.47?0.34),(5.20?0.65)ml? 100g~(-1)?min~(-1)],CBF[(280.33?8.82),(388.33?14.00),(116.16?11.54)ml? 100g~(-1)?min~(-1)],CBV[(7.75?0.27),(12.73?0.98),(5.14?0.66)ml?100g~(-1)](F=4.421,P= 0.013;F=11.370,P=0.000;F=15.789,P=0.000).There were statistical difference of PS at the different time in both the peripheral and adjacent parts of the glioma.(F=13.567,P=0.000;F=12.470, P=0.000).No difference were detected in CBF or CBV at different time of the peripheral parts of the tumors(F=1.176,P=0.336;F=0.148,P=0.710).there were significant difference between different time of tumor growth among CBF[(175.33?12.95),(275.50?13.76),(246.33?12.81)ml? 100g~(-1)?min~(-1)],CBV[(4.15?0.47),(8.05?0.30),(7.54?0.89)ml?100g~(-1)]at the adjacent parts of the tumors(F=24.176,P=0.000;F=17.148,P=0.000;F=15.791,P=0.000). Coneluslon CBV,CBF can reflect the number and volume of the tumor vessels,while PS can directly reflect the function of the angiogenesis and the behavior of the glioma.
