Luteinized unruptured follicle syndrome (LUFS), a specific type of ovulation disorder, is for a cause of female infertility. Acupuncture therapy has a good effect for LUFS. In order to understand the clinical effects and research situation of acupuncture therapy for LUFS, the author analyzed and reviewed the relevant literature. It was indicated by the findings that acupuncture therapy and integrative therapy of acupuncture and Chinese herbs have good therapeutic effect for this disease. Acupuncture therapy has the effect to promote ovulation. By the therapeutic principle to tonify the kidney and circulate blood, acupuncture therapy mostly was adopted in the period of ovulation. The acupoints are mostly selected from the lower abdomen and lower limbs, possibly based upon syndrome differentiation at the same time. The needling techniques are of certain characteristics. But, the issues of low quality, un-standardized inclusive, exclusive criteria and effective criteria still exist in the current clinical study.

The production conditions of glutathione with shaking flask fermentation by the mutant Saccharomyces J-X25, a methionine-defected strain were studied, and the optimum culture conditions are as follows: initial pH6. 0, temperature 30℃, 100ml in 500ml flask, the inoculum size 10% and agitation rate 220r/min. The emphasis was on the stimulating effect on the cells by dioxogen and the sodium lactate as surfactant. Both of which were added at the logarithmic phase of fermentation, and the GSH production was up to 0. 253g/L , 52% higher than the control without the additions. Compared with the production of GSH initial strain that by the mutant in optimum conditions was increased by 79%.

AIM: To explore the molecular mechanism of Radix Ophioponis against vascular endothelial cell (VEC) apoptosis induced by LPS. METHODS: The apoptosis of human umbilical vascular endothelial cells(HUVEC) was induced by lipopolysaccharide(LPS). The influence of Radix Ophiopogonis on the expression of bcl-2 and intracellular Ca 2+ was detected by flow cytometry and laser confocal microscope. RESULTS: The serum containing Radix Ophiopogonis suppressed the increase in bcl-2 expression and overloading of Ca 2+ induced by LPS in HUVEC.CONCLUSION: The mechanism of Radix Ophiopogonis against HUVEC apotosis may be related with its regulatory effect on bcl-2 expression and remission of Ca 2+ overloading.

Background and purpose:In the process of gastric cancer development, cytothesis and apoptosis, and endoplasmic reticulum stress (ERS) are very important pathological processes. Glucose regulated protein 78 (GRP78) and phosphorylated form of extracellular signal-regulated protein kinase (pERK) play important roles in it. This study aimed to investigate the expression of GRP78 and pERK in gastric adenocarcinoma, chronic atrophic gastritis and superficial gastritis, and the role of GRP78 and pERK in the development of gastric adenocarcinoma. Methods:Gastric adenocarcinoma, chronic atrophic gastritis and superifcial gastritis tissues in 60 cases respectively were employed in the study. We chose 25 fresh tissue samples from each group, and the level of GRP78 and pERK mRNA in different tissues were detected by RT-PCR assay. The expressions of GRP78 and pERK in different parafifn samples were detected using immunohistochemistry assay. In addition, the relationships between GRP78 and pERK expression and age, gender, differentiation, invasion, disease stage, and lymphoid node metastasis were analyzed. Results: The expression level of GRP78 and pERK mRNA in gastric adenocarcinoma(1.26±0.18, 2.35±0.36) were significantly higher than chronic atrophic gastritis (0.89±0.25, 1.18±0.25) and superficial gastritis (0.29±0.09, 0.68±0.10, P<0.01). The positive ratio of GRP78 expression in gastric adenocarcinoma, chronic atrophic gastritis and superficial gastritis were 78.3%, 46.6%, 6.7%. The positive ratios of pERK expression were 88.3%, 43.3%, 5.0%, respectively. The GRP78 and pERK expression in different tissues were signiifcantly different (P<0.01). GRP78 and pERK expression were positively correlated with differentiation, disease stage and lymph node metastasis. There was a positive correlation between the gene and protein expression of GRP78 and pERK with a Pearson correlation value of 0.307 and 0.368, respectively. Both univariate and multivariate analysis revealed that GRP78 was related to the prognosis of gastric adenocarcinoma. Conclusion:GRP78 and pERK may play an important role in the transition of normal gastric cells to malignant cells. The expression of these two genes enhances tumor progression. Overexpression of GRP78 and pERK is significantly correlated with poor prognosis in patients with gastric adenocarcinoma. The determination of the expression of GRP78 and pERK might be helpful for the prevention, early diagnosis of gastric carcinoma. Particularly, GRP78 is valuable for the judgement of prognosis, and might be a new target for the treatment of gastric adenocarcinoma.

Objective To investigate the effect of deferasirox on DLL4 expression and angiogenesis in a narrow pedicle and random flap in rats.Methods Twenty SD rats were randomly divided into the deferagirox group and control group.Rats were subjected to deferagirox of 100 mg · kg-1 · d-1 inthe experimental groups,respectively and the same dose saline in the control group for 1 week. In each group,flap were created in the bilateral back of each rats.Ratio of length to width of tissue in the pedicle portion and the flap portion was 1 cm × 1 cm and 3 cm × 3 cm,respectively.The tissue samples were taken from the pedicle and the middle portions of the flap.The DLL4 and CD105 expression was also detected with immunohistochemistry (SABC).Results Compared with control group,whatever in the pedicle portion or the middle portion,there was a significant increase of microvessels marked by CD105 and a significant decrease of flap microvessels stained by DLL4 in the deferagirox group.In both groups,compared with the pedicle portion,there was a significant increase of microvessels marked by CD105 and DLL4 in the the middle portion.Conclusions Deferasirox can in crease the CD105 expression and angiogenesis of the slender narrow pedicle random flap.This process might be related to the inhibition of DLL4 protein expression,which is significant in the notch signaling pathway.

Objective To study the effect of sanguinarine on the growth and radiosensitivity of ovarian cancer SK-OV-3 cells.Methods Cell growth was determined by MTT and clonogenic assay.Cell cycle analysis was performed by flow cytometry assay.The cell apoptosis was analyzed by Annexin V/PI assay.Results Sanguinarine inhibited SK-OV-3 cell growth in a dose-and time-dependent fashion and its IC50 values were 3.02 and 1.11 μmol/L at 24 and 48 h,respectively. Sanguinarine also significantly triggered a sub-G1 peak,an indicator of apoptosis,and caused a G0/G1 arrest.Furthermore,the cell apoptosis induced by X-irradiation was significantly increased at 6 Gy when the cells were pre-treated with sanguinarine,in which the early apoptotic population increased from 10.28％ to 43.28％ (t =19.41,P ＜0.01 ) and the late apoptotic population increased from 20.26％ to 30.80％ ( t =8.78,P ＜ 0.01 ).The multi-target click model was used to fit survival curves and the SER of sanguinarine treatment approached to 1.625 at the dose of D0. Conclusions Sanguinarine could inhibit SK-OV-3 cell growth by inducing apoptosis and cell cycle arrest and enhance cell radiosensitivity at low doses.
