Galectins can recognize and specifically bind to β-galactosidase,and regulate the transformation and survival of tumor cells,and promote the migration and metastasis of tumor cells,etc.Galectins correlate with tumor diagnosis,progression and prognosis.Galectias also can serve as immunoregulatory molecules to regulate the survival,activation,proliferation and differentiation of immune cells,and are components of tumor immune microenvironment.

Myeloid-derived suppressor cells (MDSCs) are a group of heterogeneous and immature myeloid-derived cells,which accumulate largely in blood,lymphoid organs,spleen and tumor tissue and so on under the different pathogenic conditions such as infection,trauma,hematosepsis,especially tumor and so on.MDSCs can suppress tumor immune through many mechanisms.The number of MDSCs in periphery blood of patients is closely related with tumor stage,tumor burden,remote metastasis and prognosis.The major results are from laboratory mice.Because of the complexity of MDSCs in patients with tumor,there are many difficulties and debate on the research of them,and the researches of human MDSCs progress slowly.

Myeloid-derived suppressor cells (MDSCs) play an important immunosuppressive role during the tumor development process.And the progression of many tumors are always accompanied with abnormal accumulation of MDSCs.Moreover,both the accumulation and functions of MDSCs could be affected by complicated factors.Therefore,how to effectively reduce the immunosuppressive effects of MDSCs in oncotherapy has become the focus of scholars.Recent studies show that anti-tumor drugs can affect many biological behaviors of MDSCs.

The role of DS-182 in protection of cellular damages induced by oxygen free radicals was studied in rat cardiac mitochondria. The changes of cardiac mitochondrial enzyme (cytochrome oxidase) and P/O, RCR were used as indices of mitohondrial injury. The experimental animals were divided into three groups: control group, injury group (Fe~(2+)+ascorbic acid), and protection group (DS-182+Fe~(2+)+ascobic acid). Results obtained showed that incubation of mitochondrial suspension with ascorbic acid and Fe~(2+) resulted in decrease of activity of cytochrome oxidase, P/O (with ?-ketoglutarate andsuccinate as substrate respectively) and RCR, which indicated that the structure and function of mitochondria were damaged. Danshensu (DS-182) can inhibit the decrease of cytochrome oxidase activity, P/O and RCR. Thus, DS-182 with acts as an effective scavenger for oxygen free radicals prevented the mitochondrial injury.

Regorafenib,an oral multi-kinase inhibitor,can inhabit a class of receptor tyrosine kinase,such as angiogenic,stromal,oncogenic and so on.Studies in vitro and clinical trials indicate that Regorafenib has significant antitumor activity.The results of clinical trials are encouraging for the treatment of Refractory solid tumors,especially for colorectal carcinoma.

The main factors which affect the farmers'participation in the new rural cooperative medical service are the problems,which exist in the system of the rural cooperative medical service,the institutions of medical service,the government and the farmers themselves etc.Only by constituting the corresponsive policy measures according to these factors can the farmers actively participate in the new rural cooperative medical service.

Objective To investigate the feasibility and safety of periareolar incision in treating gynecomastia, and whether it produces good cosmetic effects. Methods A total of 42 patients with gynecomastia treated by micro-incision of areola were retrospectnely anslyzed. Results The operation was successfully performed in all the 42 patients. Follow-up was done for 3 to 24 months, the surgical scars were obscure, and the sensation of nipple or areola were good. No operation-related complications were observed. Conclusion The periareolar incision in the treatment of gynecomastia was feasible and recommendable in terms of cosmetic maintenance and safety.

Objective To observe the clinical effect of modified B-lynch suture in the treatment of patients with pernicious placenta pre-via.Methods A total of 46 patients with pernicious placenta previa in our hospital were randomly divided into the modified B-lynch suture treatment group(modified group)and the conventional therapy group(convention group),with 23 cases in each group.The operation time, menstrual recovery time and lochia sanguinea time,postpartum hemorrhage,intraoperative blood soss,abnormal temperature time,placenta ac-creta,hysterectomy and neonatal asphyxia between the two groups were compared.Results The intraoperative blood soss and postpartum hemorrhage of modified group was less than those of convention group,the menstrual recovery time was shorter than that of convention group and the rate of resection of uterine was lower than that of conventional group,with significant difference (P <0.05).There was no statistically significant difference in operation time,abnormal temperature time,lochia sanguinea time,placenta accreta and neonatal asphyxia between two groups (P >0.05).Conclusion The clinical effect of modified B-lynch suture in the treatment of dangerous placenta previa is significant.

BACKGROUND: Chinese medicine Gukang prescription has a clear effect on clinical treatment of osteoporosis, but the therapeutic pathway is stil unclear.
OBJECTIVE:To investigate the effects of Chinese medicine Gukang on the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin by regulating core binding factor alpha 1 expression to control the growth and development of osteoblasts.
METHODS:Sprague-Dawley neonatal rats within 24 hours after delivery were used for the separation and culture of osteoblasts. Adult Sprague-Dawley rats were used to prepare drug-containing serum, and then divided into two groups randomly:normal control group and Gukang group. Rats in the normal control and Gukang groups were intragastrical y administrated with extract of Gukang prescription and normal saline based on rat’s body surface area, for 1 consecutive week. Two hours after the last administration, blood samples were taken from the heart. Then the serum was col ected. Osteoblasts at passage 3 were confirmed with alkaline phosphatase assay and digested. After counting and planting, al osteoblasts were divided into two groups and treated with col ected
serum for 72 hours. Proliferative rate of osteoblasts was detected by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test. Secretion of alkaline phosphatase was detected by using enzyme linked immunosorbent assay and corrected with the corresponding absorbance value. mRNA expression of core binding factor alpha 1, receptor activator of nuclear factor kappa B ligand and osteoprotegerin were detected by using reverse
transcription-PCR in al groups.
RESULTS AND CONCLUSION:mRNA expression of osteoprotegerin and core binding factor alpha 1 in the Gukang group was significantly higher than that in the normal control group, but protein and mRNA expression of receptor
activator of nuclear factor kappa B ligand were dramatical y lower in the Gukang group compared with the normal control group (P<0.01). These findings indicate that Chinese medicine Gukang prescription can modulate the expression of
core binding factor alpha 1, thereby adjusting the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin, which may be one of the mechanisms underlying Gukang treatment for osteoporosis.
