Objective To explore the effects ofCangfu Congxian Decoction on the mRNA expression of IGF-1R in human mural granulosa cells;To explore the action mechanism for the treatment of polycystic ovary syndrome (PCOS) patients.Methods Totally 48 patients undergoing IVF-ET were randomly divided into treatment group and control group by random number table, 24 cases in each group. Patients in the control group accepted GnRHa/FSH/hCG stimulation, while the treatment group tookCangfu Congxian Decoction orally on the basic treatment of the control group. Serum E2, LH, and P concentration on HCG injection day, number of ovum, high quality embryo rate and clinical pregnancy rate were evaluated. The mRNA expression of IGF-1R on mural granulosa cells in the mature follicle was detected by real-time PCR.Results Compared with the control group, there was no significant difference in serum E2, LH, and P concentration on HCG injection day of treatment group (P>0.05), while the treatment group had higher high quality embryo rate than that of the control group (P<0.01). There was no significant difference in the number of ovum and pregnancy rate between the two groups (P>0.05). The mRNA expression of IGF-1R on granulosa cells in treatment group was significantly higher than the control group (P<0.01).Conclusion The mechanism ofCangfu Congxian Decoction for treating PCOS is up-regulating the mRNA expression of IGF-1R in mural granulosa cells and increasing high quality embryo rate.

Objective: To investigate the loneliless situation of the elderly, and explore the relationship between loneliness,filial expectations and intergenerational social support among the elderly. Methods: Using UCLA Loneliness Scale, Intergenerational Social Support and Fealty Expectation Questionnaire, we investigated 423 samples of old people aged 60 ~94 of Changsha City. Results: The mean score of loneliness was 39.8 (s =7.3). Ordinal regression analysis indicated that the loneliness of the elderly was significantly related to received adult children social support (OR=2.208, P=0.006),afforded adult children social support(OR=2.056,P=0.01) and filial expectation(OR=1.872,P=0.027),controlled by age, sex, level of education, marriage, level of family income, and residence status. Filial expectation directly affected loneliness and indirectly affected loneliness through received adult children social support and afforded adult children social support. Conclusion: The loneliness of the elderly are significantly related to filial expectation and intergenerational support.

Objective Up to now, there has been no sure cure for genital herpes (GH), and vaccine seems a most promis-ing approach to the prevention and treatment of herpes simplex virus Ⅱ(HSV-2) infection.In this study, we investigated the feasibili-ty of preparing a dendritic cell ( DC) vaccine modified by the adenovirus-mediated HSV-2 gD gene. Methods We subcloned the HSV-2 gD gene into the vector Shuttle-2 and constructed the recombinant adenovirus pAdeno-HSV-2 gD following identification by en-zyme digestion and DNA sequence analysis .We isolated DCs from the mouse bone marrow , analyzed their phenotypes by flow cytome-try after transfection with the recombinant adenovirus pAdeno-HSV-2 gD, and determined the expression of HSV-2 gD by immunohisto-chemistry, RT-PCR, SDS-PAGE, and Western blot. Results Based on HSV-2 DNA, the corresponding target fragments were am-plified with the gD gene primers.Agarose gel electrophoresis showed the correct size of the PCR product (1182 bp) as predicted.The recombinant adenovirus pAdeno-HSV-2 gD was obtained by transfecting the 293 cells with pAdeno-gD DNA, which had an activity of 4 ×1010 IU/mL.The contents of CD40, CD80, and CD86 were (74.2 ±3.9), (73.9 ±4.1), and (76.1 ±5.5) % in the mature DCs and (81.3 ±3.1), (80.4 ±2.9), and (83.7 ±3.9) % in the pAdeno-HSV-2 gD DCs, significantly increased as compared with those in the immature DCs ([9.7 ±0.5], [7.5 ±1.2], and [5.2 ±1.1] %) (P<0.01).No statistically significant differ-ences were found between the expression of the surface molecules in the pAdeno -HSV-2 gD DCs and that in the cytokine stimulation-in-duced mature DCs (P>0.05).RT-PCR and immunohistochemistry confirmed the expression of HSV-2 gD in DCs.SDS-PAGE and Western blot of the expressed protein showed a new band with an apparent molecular mass corresponding to the predicted size (43000). Conclusion The results of our study have paved the ground for the successful preparation and identification of a dendritic cell vaccine modified by the adenovirus-mediated HSV-2 gD gene.

Objective To screen for genes associated with low-dose UVA irradiation-induced adaptation reaction in cultured human melanocytes, and to explore the molecular mechanism of the adaptation.Methods Cultured human melanocytes of fifth to tenth passage were divided into two groups, experimental group was subjected to an irradiation with UVA at 7.2 J/cm2 once daily for 4 times and an additional irradiation at a lethal dose of 86.4 J/cm2 6 hours after the above 4-session irradiation, and control group subjected to a single irradiation with UVA at 86.4 J/cm2. A human genome-wide oligonucleotide chip was used to screen for differentially expressed genes between the two groups of cells followed by a functional classification based on international standard. Moreover, a part of these genes were analyzed and identified by real-time fluorescent quantitative PCR. Results In the adaptation reaction induced by low-dose UVA irradiation in cultured melanocytes, there were 129 differentially expressed genes, including 81 up-regulated genes and 48 down-regulated genes. These genes were found to be mainly involved in metabolism, transport, signal transduction, apoptosis, DNA synthesis and repair, and some of them were oncogenes or anti-oncogenes. Real-time PCR confirmed some of the differentially expressed genes. Conclusions The whole genome-wide oligonucleotide chip could screen with high efficiency for differentially expressed genes in low-dose UVA irradiation-induced adaptation reaction in cultured melanocytes.
