Objective To evaluate the efficacy of Jianpi-Gushen decoction combined with vitamin E and human chorionic gonadotropin for the patients with threatened abortion in early pregnancy. Methods A total of 154 patients with threatened abortion who met the inclusion criteria were divided into two groups by a random digital table, with 77 patients in each. The control group was treated with intramuscular injection of human chorionic gonadotropin (HCG) combined with vitamin E, while the observation group was treated with Jianpi-Gushen decoction based on the treatment of control group. The levels of serum β-HCG were detected by radioimmunoassay before and after treatment, and the levels of progesterone were detected by electrochemiluminescence assay, and the efficacy was evaluated. Results The total effective rate in the observation group was 90.9% (70/77), and control group was 77.9% (60/77). The difference between two groups was significantly different (χ2=4.936, P=0.026). The serum β-HCG level (22383.41 ± 4387.67 mIU/ml vs. 15728.66 ± 3375.93 mIU/ml, t=5.614) and progesterone level (58.53 ± 18.77 nmol/L vs. 43.45 ± 17.46 nmol/L, t=2.674) in the observation group after treatment were higher than those in the control group (P<0.01). Conclusions The Jianpi-Gushen decoction combined with vitamin E and HCG could increase the levels of serum β-HCG and progesterone and improve the clinical effect.

Objective To develop and verify an influenza A virus antigen-detecting kit which can detect all the subtypes of influenza A virus. Methods Double-antibodies sandwich enzyme linked immunosorbent assay (ELISA) was utilized for developing the influenza A virus antigen-detecting kit. The sensitivity, specificity, accuracy and stability of the kit were evaluated by the clinical samples. Results The lower detection limit of the kit for the N protein was 7. 63 ng/mL, which was 256 times lower than that of the hemagglutination and 16 times lower than that of immune colloidal gold technique. The kit didn't show any cross-reaction with the influenza B virus, respiratory syncytial virus, respiratory adenovirus, para-influenza virus type Ⅰ and Ⅲ, mycoplasma pneumomiae, avian newcastle disease virus, avian infectious bursal disease virus or avian infectious bronchitis virus. The specificity was 100%. Both the intra batch variaton coefficient (CV) value and inter batch CV value were less than 15%, which met the national standard for ELISA kits. The results proved that the kit could keep stable at 4 ℃ for more than 1 year and at 37 ℃ for more than 7 days. The kit could identify H1N1, H3N2, H5N1 and H9N2 influenza A viruses. The clinical research data of human influenza virus showed the consistency rate between the kit and regular cell culture method was 93. 44% for the positive samples and 99. 31% for the negative samples. The clinical research data of avian influenzavirus showed the consistency rate between the kit and regular cell culture method was 95. 45% for positive samples and 98. 09% for negative samples. Conclusion The influenza A virus antigen-detecting ELISA kit can be used for the epidemiological survey of the infection of human influenza A virus or avian influenza virus with high sensitivity and specificity.

In order to investigate the effects of TGF-beta1 on the expression of MMP-2, -9 and TIMP-1 in human retinal pigment epithelial (RPE) cells, the third-sixth passage cultured RPE cells were treated with TGF-beta1 at different concentrations (0.01, 0.1, 1.0, 10 ng/mL), the expression of MMP-2, -9 and TIMP-1 mRNA was detected by semi-quantitative RT-PCR assays. MMP-2, -9 and TIMP-1 mRNA were expressed in the cultured RPE cells. The values of MMP-2/beta-actin in the cells treated with 0.1, 1.0, 10 ng/mL TGF-beta1 were 1.04 +/- 0.04, 1.07 +/- 0.02 and 1.11 +/- 0.03, respectively, significantly higher than in the control group (0.96 +/- 0.03, P < 0.05-0.01). The expression of MMP-2 mRNA could be up-regulated by TGF-beta1, in a dose-dependent manner. The expression of MMP-9 mRNA in the cultured RPE cells was slightly up-regulated by various TGF-beta1 concentrations treatment. The values of TIMP-1/beta-actin in the cells treated with 0.01 and 0.1 ng/ mL TGF-beta1 were 0.85 +/- 0.01 and 0.97 +/- 0.02 respectively, significantly lower than in the control group (1.07 +/- 0.04, P < 0.01), indicating that the expression of TIMP-1 mRNA was down-regulated by TGF-beta1 at low concentrations. But along with the increase of TGF-beta1 concentrations (1.0 and 10 ng/mL), the expression of TIMP-1 mRNA was slightly up-regulated, not significantly different from that in the control group (P > 0.05). It was concluded that TGF-beta1 might play an important role in the up-regulation of the expression of MMP-2 in RPE cells and result in a directional shift in the balance between MMP and TIMP. This may be facilitated for RPE cells to migrate in the pathogenesis of vitreoretinopathy.

AIM:To investigate the effects of pioglitazone on the quantity and function-related factors of regu-latory and effector T cells ( Treg and Teff ) of uremic apolipoprotein E knockout mice in vitro with or without the stimulation of atherosclerotic plaque-specific antigen oxidized low-density lipoprotein ( oxLDL) .METHODS:Uremic apolipoprotein E knockout mouse model was established by 2-step surgical procedure.After intervention with different concentrations ( 2μmol/L and 20μmol/L) of pioglitazone and PPARγantagonist GW9662 (5μmol/L) on splenocytes of uremic mice for 12 h in the presence or absence of oxLDL (2 mg/L), the levels of CD4 +CD25 +Foxp3 +Treg and IFNγ+CD4 +Teff were de-termined by flow cytometry.The mRNA expressions of Foxp3 and IFNγwas detected by real-time fluorescent quantitative PCR.RESULTS:In vitro, oxLDL induced a Treg/Teff imbalance in splenocytes from the uremic mice.Pioglitazone up-regulated the level of Treg and mRNA expression of Foxp3 in the presence of oxLDL, which was not antagonized by GW9662.Meanwhile, pioglitazone downregulated the level of Teff and mRNA expression of IFNγin the presence or ab-sence of oxLDL, which was reversed by GW9662.CONCLUSION:oxLDL induces a Treg/Teff imbalance in uremic apo-lipoprotein E knockout mice.Pioglitazone modulates the Treg/Teff imbalance probably through PPARγ-independent and-dependent mechanisms.
