Objective To discuss the clinicopathologic characteristics and risk factors for lung metastasis of early-stage cervical cancer after radical hysterectomy. Methods The complete clinicopathologic data of patients with lung metastasis of cervical cancer after radical surgery from January 2008 to December 2013 admitted in Zhejiang Cancer Hospital were retrospectively analyzed by univariate and multivariate analysis. Results (1)There were 38 cases of early cervical cancer suffered from lung metastasis after radical hysterectomy during the period. The median age at diagnosis of cervical cancer was 46 years, the average lung metastasis time was 13 months after operation, 50.0%(19/38) cases occurred in the first year. Thirty-one cases were squamous cell carcinoma and 7 cases were non-squamous cell carcinoma.(2)Univariate analysis showed that age,clinical stage, manner of tumor growth, tumor grade, perineuronal invasion, para-aortic lymph node metastasis were not significant effect on postoperative lung metastasis(all P>0.05). But tumor size, histologic types, depth of stromal invasion, uterine body infiltration, lympho-vascular space invasion,pelvic lymph node metastasis, positive margin and abnormal tumor markers were significantly correlated with postoperative lung metastasis(all P<0.05). Multivariate analysis showed that only tumor size, histologic types and pelvic lymph node metastasis were independent risk factors for lung metastasis of cervical cancer(P<0.05). Conclusions Patients of early-stage cervical cancer with lung metastasis mostly occurs within 1 year after radical hysterectomy. Local large tumor lesions (tumor size>4 cm), non-squamous cell carcinoma and pelvic lymph node metastasis were more likely to have lung metastasis.

Diabetes mellitus is a worldwide public health problem,which is a serious threat to human health.WHO released the global diabetes report shows Chinese incidence of type 2 diabetes was explosive growth in the past few decades,but public awareness of diabetes is generally inadequate,especially at the grassroots level.Therefore,it is imperative to regulate the basic level of diabetes diagnosis and treatment.As one of the basic measures of diabetes treatment in our country,education and management of diabetes' foundation is weak,mainly for the lack of national basic medical and health institutions,dull form of education and lack of target,shortages of specialized diabetes staff.So in order to safeguards the success of primary diabetes education and management and improve the prevention of primary diabetes,it is necessary to establish a sound mechanism of reward system,make full use of various payment platform,strengthen the basic management of diabetes monitoring information construction and carry out the Internet education measures.This article reviews the current situation of education and management of primary diabetes.

Objective To investigate COL1A1 gene mutation by PCR-high resolution melting (PCR-HRM) and an-alyze the correlation between genotype and clinical phenotype in a child (proband) with osteogenesis imperfecta (OI). Methods The family history of OI pedigree along with the clinical data was collected. Blood samples from the proband and his family members, as well as 50 normal controls, were collected. The mutation of COL1A1 gene was screened using PCR-HRM and validated by the gene sequence. Results The detection of PCR-HRM showed the abnormal result of COL1A1 17 exon in proband with a lower melting temperature (Tm) value than that of normal controls by 0.4℃. There were signifi-cant differences in the standardization melting curve and the different melting curve between the proband and the normal controls. The sequencing result was c.1138G>A, which meant that cDNA of 1138 base G mutation into A. The mutations transformed the amino acid glycine into a serine at amino acid 380(P. Gly 380 Ser), which resulted in missense mutations. The proband’s father and grandmother had the same mutation of COL1A1 gene. The mutation was not found in the proband’s mother and normal controls. There was no report for such mutation in Chinese population. Pedigree analysis showed the fami-ly genetic characteristics of autosomal dominant inheritance. The proband was clinically diagnosed as OI type Ⅳwith more severe clinical phenotype. Conclusion PCR-HRM analysis is a new effective method for genetic screening of OI. COL1A1 mutation of c.1138G>A is a newly discovered mutation in Chinese population. Gly replaced inαhelical domain may lead to a more severe clinical phenotype.

Objective To explore the effects of traditional Chinese formula Danchaiheji on the differentiation of regula?tory dendritic cells (DCs) and the underlying mechanism. Methods The rat blood serums with or without the formula Dan?chaiheji were prepared. The peripheral blood mononuclear cells were separated from the peripheral venous blood of healthy donors. CD14+monocytes were isolated using CD14+magnetic beads and cultured for 5-7 days to obtain immature dendritic cells (imDCs). Then the cells was divided into control group and Danchaiheji containing rat serum group. Control group was divided into two subgroups (containing LPS and without LPS). Danchaiheji containing rat serum group was also divided into two subgroups (containing LPS and without LPS). The surface markers CD86, CD11b and HLA-DR of DCs were detected by flow cytometry. The level of IL-10 was determined by enzyme-linked immunosorbent assays (ELISA). The proliferation of al?logeneic T-cells was detected by flow cytometry and the expression level of indoleamine 2,3-dioxygenase (IDO) was deter?mined using quantitative real-time PCR. Results DCs treated with the formula Danchaiheji exhibited high CD11b and low CD86 and HLA-DR expression levels as well as promoted the secretion of IL-10. In addition, the drug could inhibit the pro?motion of DCs on the proliferation of T cells, which was associated with the up-regulation of IDO expression. Conclusion The traditional Chinese formula Danchaiheji can induce the differentiation of DCs into regulatory DCs and play a role in in?hibitory effect on immune function.

Objective To investigate the clinical efficacy of trimebutine combined with Xiangsha Pingwei in the treatment of functional dyspepsia and its effect on gastrointestinal hormone.Methods One hundred and twenty cases of functional dyspepsia were randomly divided into the control group and observation group,60 cases in each group.The control group was treated with trimebutine 0.2 g,3 times/d and the observation group was treated with trimebutine 0.2 g,3 times/d and Xiangsha Pingwei 10 g,2 times/d.Both groups were treated for four weeks,a course of treatment.Clinical efficacy and the influence on gastrointestinal hormone levels were compared between the two groups.Results The symptoms scores in both groups all decreased significantly after treatment.While the postprandial fullness scores,early satiety scores and epigastric pain scores in the observation group were significantly lower than those in the control group (0.62±0.12 vs.1.85±0.25,0.56±0.14 vs.1.46±0.21,0.48±0.15 vs.1.32±0.12,t=34.36,27.62,33.87,P<0.05).The total effective rate in the observation group was significantly higher than that in the control group (90.00% vs.73.33%,χ2=5.57,P<0.05).MOT and GAS levels in both groups increased significantly.While MOT and GAS levels in the observation group were significantly higher than those in the control group (MOT: (355.2±78.1) ng/L vs.(288.7±82.4) ng/L;GAS:(96.5±17.6) ng/L vs.(88.4±16.0) ng/L,t=4.54,2.64,P<0.05).The somatostatin (SS) level in both groups decreased significantly.While the SS level in the observation group was significantly lower than that in the control group ((41.1±11.1) ng/L vs.(48.9±12.9) ng/L,t=3.55,P<0.05).Conclusion Trimebutine combined with Xiangsha Pingwei can significantly improve the clinical symptoms and gastrointestinal hormone in patients with functional dyspepsia.

OBJECTIVETo investigate the expression of Toll-like receptor (TLR) mRNA in enterovirus 71(EV-A71) infected human Jurkat T cells and clarify the role of TLRs in the pathogenesis of EV-A71 infection-induced inflammation.

METHODSEV-A71 strains were isolated from feces of children patients with hand, foot and mouth disease in 2014 by Shenzhen Center for Disease Control and Prevention. Human Jurkat T cells were infected with 200 μl EV-A71 at 10(3) cell culture infective dose 50%(CCID50)/ml. The expression of TLR1-TLR10 mRNA in human Jurkat T cells was assessed at different exposure time by RT-PCR. Levels of TLR7 mRNA expression were detected by real-time PCR, and levels of myeloid differentiation factor 88 (MyD88) by western blot. The cytokine secretion of interleukin (IL)-6, IL-8 and Tumor Necrosis Factor α (TNF-α) was analyzed by ELISA assay.

RESULTSThe relative expression level of TLR7 mRNA in human Jurkat T cells were 1.26 ± 0.15, 1.75 ± 0.20, 2.26 ± 0.23 and 3.74 ± 0.62 in 6, 12, 24 and 48 h after EV-A71 infection, which the differences were significant with mock-infected group(t values were -2.96, -6.38, -9.57, -7.71; P<0.05). Western blot showed that the protein expression levels of MyD88 had increased 1.34 times and 2.17 times in 24 h and 48 h after EV-A71 infection compared with mock-infected group. After infected for 24 h and 48 h, the levels of IL-6 were (302.86 ± 38.11), (179.70 ± 14.50) pg/ml, which were significantly higher than mock-infected group (176.42 ± 9.60), (179.70 ± 14.50) pg/ml (t values were -5.57, -18.54, P<0.05). The levels of TNF-α in EV-A71 infected group (100.81 ± 9.81) pg/ml was higher than that in mock-infected group (56.19 ± 6.94) pg/ml, and the difference was significant (t=-6.43, P=0.003).

CONCLUSIONTLR7 is the main pattern recognition receptor responsible for EV-A71 recognition in immune cells, which then leads to the activation of TLR7 downstream signaling and the production of proinflammatory cytokines.

Abnormal FGFR signaling has been found in a variety of cancers. The abnormal FGFR signaling is involved in several processes of tumorigenesis which include cell survival, proliferation, inflammation, migration, angiogenesis, epithelial-mesenchymal transformation and drug resistance. Therefore, FGFR is a very promising target for the treatment of tumors. More and more FGFR inhibitors have been developed for preclinical and clinical trials, and some FGFR inhibitors have been used in clinical applications. However, the problems such as acquired resistance and systemic toxicity have hindered the application of FGFR inhibitors. This paper reviews the clinical application of common FGFR inhibitors and summarizes the problems and solutions in their application.
