OBJECTIVESTo investigate the effects of FAK-related non-kinase (FRNK) on expressions of type I collagen and matrix metalloproteinase-2 (MMP-2) mRNA and tissue inhibitor of metalloproteinase-2 (TIMP-2) mRNA in rat hepatic stellate cells (HSC).
METHODSUsing in vitro cell culture technique, FRNK plasmids were transfected into HSC mediated by cationic liposome. Type I collagen synthesis capability in HSC was examined by 3H-Pro incorporation assay. The levels of FRNK in HSC were assayed by Western blot, and the expressions of MMP-2 and TIMP-2 were assayed by RT-PCR on mRNA levels.
RESULTSThe exposure of HSC to FRNK caused the expression of FRNK protein to be up-regulated, and the FRNK protein contents reached the highest point at 48 h after the transfection, P less than 0.05. The expressions of MMP-2 mRNA were up-regulated by FRNK; the expressions of TIMP-2 mRNA were down-regulated by FRNK; the ratios of MMP-2 mRNA/TIMP-2 mRNA were enhanced by FRNK.
CONCLUSIONAfter FRNK was transfected, the capability of type I collagen synthesis in HSC was inhibited, which may be related to the up-regulation of MMP-2 mRNA/TIMP-2 mRNA.

OBJECTIVETo assess embryo implantation rate (IR) and pregnancy rate (PR) in women who received Bushen Wengong Decoction (BSWGD), a Chinese herbal formula, combined with low dose of human menopausal gonadotropin (hMG) prior to frozen-thawed embryo transfer (FET).
METHODSA total of 262 subjects (674 transferred embryos) who received FET were analyzed retrospectively. In them, 122 women were under 30 years old, 106 between 30 - 35 years and 32 over 35 years. The 85 subjects with normal ovulation were assigned to Group A, the natural menstruation cycling group, on whom no pre-transfer treatment was applied. The other 177 subjects with abnormal ovulation were assigned to Group B, and subdivided, according to the pre-transfer treatment they received, into three groups, Group B1 (50 cases) received BSWGD, Group B2 (58 cases) received hMG and Group B3 (69 cases) received both BSWGD and low dose hMG. The IR and PR of FET in the four groups were compared, and the effect of the embryo cryotime on PR of FET were compared also. Besides, the influencing factors to FET were analyzed.
RESULTSIR and PR were significantly higher in all age sects of Group B3 than those in Group A, showing significant difference (P< 0.05). IR and PR in subjects in age sects of <30 years and > 35 years in group B3 were significantly higher than those in Group B1 ( P<0.05), but no significant difference was shown in the two parameters between Group B 2 and Group B3 (P>0.05). PR in the subjects who received embryos with cryo-time of > 200 days was significantly lower than that in those with cryo-time of < 100 days ( P<0.05). Embryo cryo-time, endometrial thickness, use of BSWGD and use of hMG were of significance in FET ( P 0.05).
CONCLUSIONA programmed cycle of BSWGD combined with low dose of hMG could improve the embryo IR and PR of FET. Embryo cryo-time, endometrial thickness, and the use of BSWGD and hMG are of significance for FET.

OBJECTIVETo explore the effect of Salvia miltiorrhiza monomer IH764-3 on apoptosis in hydrogen peroxide (H2O2)-stimulated hepatic stellate cells (HSCs).
METHODSHSCs were cultured in medium with different IH764-3 doses (10 mg/L, 20 mg/L, 30 mg/L, 40 mg/L) and without IH764-3. Direct cell count, 3H-thymidine incorporation, Annexin-V/Propidium Iodide double-labeled flow cytometry, TUNEL and transmission electron microscopy were employed to estimate the influence of IH764-3 on proliferation and apoptosis of HSCs. The expression of extracellular signal-regulated kinase 1 (ERK1) mRNA and protein in HSCs were detected using RT-PCR and Western blot respectively.
RESULTSIt was showed that H2O2 could promote HSC proliferation. In contrast, IH764-3 at concentrations of 10 mg/L, 20 mg/L, 30 mg/L and 40 mg/L inhibited its proliferation. The inhibition rates were 7.13%, 28.36%, 53.80% and 73.10% (P < 0.01). And the inhibition rates of IH764-3 at concentrations of 30 mg/L at 12 h, 24 h and 48 h were 22.24%, 40.51% and 61.65%. Furthermore, IH764-3 could also induce the HSC apoptosis in dose-dependent an dtime-dependent manners (P < 0.01). In addition, after exposed of HSCs to IH764-3 for 24 h, ERK production decreased and ERK1 mRNA was down-regulated earlier about 2 h after exposure to IH764-3.
CONCLUSIONIH764-3 may inhibit the proliferation and induce apoptosis of HSCs in both dose-dependent and time-dependent manners, which may be related to down-regulation of ERK expression.

OBJECTIVETo evaluate the clinical effects of combined methods of minimally invasive percutaneous proximal humeral internal locking system (PHILOS) and injectable bone for the treatment of proximal humerus fractures in elderly patients.
METHODSFrom January 2006 to January 2012, 80 patients with proximal humerus fractures were randomly divided into two groups (n = 40). The patients in the research group were treated with minimally invasive PHILOS fixation combined with injectable bone, including 20 males and 20 females, with an average age of (68.4 +/- 11.9) years; according to AO classification, 2 cases of type A1, 3 cases of type A2, 6 cases of type B1, 7 cases of type B2, 9 cases of type B3, 6 cases of type C1, 7 cases of type C2. The patients in the control group were treated with PHILOS fixation, including 18 males and 22 females, with an average age of (65.4 +/- 10.7) years; according to AO classification, 3 cases of type A1, 4 cases of type A2, 5 cases of type B1, 8 cases of type B2, 10 cases of type B3, 5 cases of type C, and 5 cases of type C2. The BMD, satisfactory rate, postoperative complications,bone healing time, Constant-Murley score in the two groups were reviewed and compared.
RESULTSIn the research group, no patients had necrosis of femoral head, 1 patient had shoulder varus, 1 patient had internal fixation loosening, 36 patients were satisfactory with the treatment results, BMD was (1.013 +/- 0.109) g/cm2, bone healing time averaged (12.00 +/- 3.79) weeks, and the Constant-Murley score was 97.2 +/- 4.6. In the control group, 3 patients had necrosis of femoral head, 5 patients had shoulder varus, 6 patients had internal fixation loosening, 32 patients were satisfactory with the treatment results, BMD was (0.812 +/- 0.089) g/cm2, bone healing time averaged (20.00 +/- 8.67) weeks,and the Constant-Murley score was 78.5 +/- 3.2. The results of BMD, satisfactory rate, postoperative complications, bone healing time, and Constant-Murley score in the research group were better than those of control group (P < 0.05).
CONCLUSIONPHILOS combined with injectable bone for the treatment of proximal humerus fractures in elderly patients has advantages of minimal wound, stable fixation, and earlier rehabilitation.
