OBJECTIVE: To study the potential targets and action mechanism of apatinib-treated breast cancer. METHODS: Combination with bioinformatic analysis, PharmMapper reverse docking technology was used to predict potential targets of apatinib and docking was performed using Autodock 4. 0 to examine the interaction of aptinib wih predicted protein targets. RESULTS: Cell division protein kinase 2,GTPase HRas, NONE and cytochrome P450 2C9 were found to be the potential targets of apatinib-treated breast cancer. Stable hydrogen bonds were formed between apatinib and the four predicted targets, and the binding free energy was low. CONCLUSION: Apatinib maybe participate the functional regulation or biological action of cell division protein kinase 2, GTPase HRas, NONE and Cytochrome P4502C9 to treat breast cancer, which provides a theoretical basis and a clue for further exploration of the mechanism research of apatinib-treated breast cancer.

OBJECTIVETo explore the correlation between pathological characteristics of target organs and excess evil syndrome in IgA nephropathy.

METHODSData were collected in multicenter cooperation. Totally 266 IgA nephropathy patients were typed into exogenous wind-heat affection syndrome (49 cases), lower energizer damp-heat syndrome (100 cases), damp-phlegm syndrome (43 cases), and blood stasis syndrome (74 cases). Meanwhile, percutaneous renal biopsy was performed in all patients for Hass classification, Oxford classification, Katafuchi integral, and Jiang's classification methods. The correlation between excess evil syndrome and pathological index was analyzed.

RESULTSFour syndrome types were correlated with their Hass levels (r = 0. 341, P <0. 01). Affection of exogenous wind-heat syndrome was correlated with segmental proliferation of endothelial cells and damaged active lesions of segmental capillary loops. Lower-energizer damp-heat syndrome was associated with Hass III level, destroying active lesions of capillary loops, segmental proliferation of endothelial cells, glomerular segmental lesions, focal interstitial infiltration of inflammatory cells, focal interstitial fibrosis and tubular atrophy. Blood stasis syndrome was associated with Hass IV level, glomerular sclerosis, segmental glomerulosclerosis (S)/adhesion, mesangial hypercellularity (M), angiohyalinosis, multi-foci interstitial infiltration of inflammatory cells, multi-foci interstitial fibrosis and tubular atrophy. Phlegm-damp syndrome had higher proportions of Hass I and III levels, but with no association with other pathological parameters.

CONCLUSIONSExcess evil syndrome was associated with partial pathological characteristics of IgA nephropathy. It could reflect pathological damage degree of target organs, activities, chronic lesions, and prognosis of IgA nephropathy to certain extent. Correlated pathological characteristics and its evolution could indicate excess evil syndrome types and their evolution rules.

OBJECTIVETo investigate the expression of proline-rich tyrosine kinase-2 (Pyk2) in human primary colorectal carcinoma (CRC) and it's prognostic significance.

METHODSThe expression of Pyk2 was retrospectively examined with immunohistochemistry (IHC) in 108 tissues of primary CRC. The correlation of Pyk2 expression to prognosis and relevant clinical factors were analyzed.

RESULTSThe rate of Pyk2 low-expression in CRC was 56.5% (61/108). The expression of Pyk2 correlated significantly to the histological grade (P < 0.05) and the TNM stage (P < 0.05), while no correlation between Pyk2 expression and age, tumor size (P > 0.05). Patients with Pyk2 over-expression had significantly higher 5-year survival rate (66.0%) than those with Pyk2 low-expression (31.4%). Pyk2 expression, together with carcinoma histologic grade and TNM stage were prognostic factors to CRC on the multivariate analysis.

CONCLUSIONSPyk2 expression can be a prognostic factor to the CRC patients together with other predictors.

OBJECTIVETo evaluate the frequency and nature of E-cadherin gene (CDH1) germline mutations in familial gastric cancer kindreds of china.

METHODSFive familial gastric cancer kindreds of Chinese origin were screened for germline CDH1 mutations, all of them meeting the clinical criteria for hereditary diffuse gastric cancer (HDGC), by PCR-DHPLC and direct sequencing.

RESULTSA new truncating mutation in exon 10 in B family was identified, producing a stop codon at position 503 (Q503X), resulting in a truncated protein. The proband of this family had metachronous development of lobular breast and diffuse type gastric carcinoma. No protein expression was detected in the lobular breast carcinoma, indicating complete inactivation of the gene.

CONCLUSIONSA Chinese gastric cancer family with CDH1 germline truncating mutation is described for the first time, and our findings suggest that lobular breast carcinoma might be part of the tumor spectrum of HDGC.

·AIM:To investigate the clinical efficacy of Ranibizumab combined with laser photocoagulation in the treatment of proliferative diabetic retinopathy (PDR). ·METHODS: Totally 80 patients (101 eyes) with PDR admitted to our hospital from October 2014 and October 2016 were selected and divided into the observation group and the control group, with 50 eyes and 51 eyes respectively. The patients in the control group (50 eyes) were treated with panretinal photocoagulation (PRP), and the patients in observation group (51 eyes) were treated with ranibizumab on the basis of PRP treatment. Best corrected visual acuity(BCVA) was compared before and after surgery 1, 3, and 6mo. Optical coherence tomography (OCT) was used to examine the central macular thickness ( CMT ) and the area of neovascularization at each timepoints. Then the laser spot number,laser energy and energy density were compared between the two groups and the adverse reactions were recorded. · RESULTS: Postoperative BCVA of the two groups significantly increased, and the BCVA of observation group were significantly higher than that of the control group after surgery 1, 3, 6mo, the difference was statistically significant (P<0. 05). After treatment, the CMT and neovascularization area of the two groups significantly decreased, and those of the observation group were significantly lower than those of the control group after surgery 1, 3, 6mo, the difference was statistically significant (P<0.05). The laser spot number, laser energy and energy density of the observation group were significantly lower than those of the control group, the difference was statistically significant(P<0.05). There were 2 cases (2 eyes) in the observation group and 1 cases (1 eye) in the control group, whose intraocular pressure exceeded 28mmHg, while relieved rapidly after the treatment, and no obvious complications occurred in two groups. ·CONCLUSION:Ranibizumab combined with laser in the treatment of PDR is an effective and safe way to improve BCVA, reduce CMT, and eliminate new blood vessels with less required laser energy.

Objective To study the feasibility of the therapy for the preoperative preparation maternal anxiety with patient-controlled transcutaneous electrical stimulation on auricular Shenmen point in cesarean section.Methods Totals of 60 primiparas (SAS score ＞ 30)who underwent elective cesarean section were randomly divided into experiment group ( n =30 ) and control group ( n =30 ).Experiment group received patient-controlled sedation with transcutaneous electrical stimulation on auricular point after enter into the operating room (took Shenmen point frequency 1.5 Hz).And the strength was controlled by themselves,continued stimulation for 30 minutes.While control group didn' t receive electrical stimulation.The indexes were observed such as HR,MAP,fetal heart rate when the women came to the operating room (T0 ),after receiving 30 minutes stimulation (T1),and the VAS score and the concentration of plasma angiotensin Ⅱ was compared.Results HR,MAP,VAS score and the concentration of plasma angiotensin Ⅱ of experiment group were (72 ± 9 ) bpm,( 84 ± 11) mm Hg,(49.8 ± 20.8 ),and (73.9 ± 21.8 ) ng/L,respectively,which was lower than that of the control group,and the difference was statistically significant (t =2.143,2.648,3.576,2.163 ; P ＜0.05).There was no significant difference found in the fetal heart rate between two groups ( P ＞ 0.05 ).Conclusions Patient-controlled transcutaneous electrical stimulation on auricular Shenmen point can keep calm,decrease MAP and restrain the stress response of maternal in cesarean section for preoperative preparation.

Objective To observe the effects of therapy of wound-pus promoting granulation tissue growth guided by drug-wound interaction theory on the related factors in granulation tissue during the healing of chronic skin ulcer in rats based on drug-wound interaction. Methods Twenty-four rats were randomly divided into normal group, model group, control group, and treatment group, 6 rats in each group. The rats in the normal group had no skin ulcer and was given normal feeding,and the rats with chronic skin ulcer in the other 3 groups were induced by compound factors-overlapped method of hormone intervention-skin defect-bacterial infection. After modeling,the model group was given external use of saline gauze dressing,the control group given external use of vaseline gauze dressing,and the treatment group given external use of Shengji Xiangpi Ointment,changing fresh dressing for wound daily,the treatment lasting for 14 days. Wound sample was taken from the left back of rats, and therapeutic effect was evaluated according to the changes in the wound surface of the rat right back. After intervention for 3,7,and 14 d,the secreta and granulation tissue in the wound surface of rats were observed, the expression levels of vascular endothelial growth factor (VEGF), inducible nitric oxide synthase(iNOS), arginine-1 (Arg-1), and Notch1 in granulation tissue of rat ulcer wound were measured by enzyme-linked immunosorbent assay (ELISA). Results The wound in the treatment group has been healed after treatment for 14 days (P < 0.05 or P < 0.01 as compared with the diameter of the ulcer in the model group and the control group) . At the early stage of wound repairing (3 d),the expression levels of VEGF and Arg-1 in the treatment group were increased, and Notch1 expression level was decreased, the difference being statistically significant as compared with those of the model group and the control group (P < 0.05). At the late stage of wound repairing (14 d),the expression level of iNOS in the treatment group was increased,and the difference was statistically significant as compared with that of the model group(P < 0.05). Conclusion The therapy of wound-pus promoting granulation tissue growth guided by drug-wound interaction theory can promote the healing of chronic skin ulcerative wound in rats and improve the general condition of rats. The therapeutic mechanism may be associated with firstly inhibiting the expression of iNOS induced by M1 type macrophage at early stage and then promoting M2 type macrophage phenotype index Arg-1 expression,and regulating the expression of VEGF and Notch1 in the granulation tissue.

[Objective]To compare early serum beta-human chorionic gonadotropin (β-hCG) levels after cleavage or blastocyst embryo transfers (ET) in predicting pregnancy outcome.[Methods]A total of 2421 IVF-ET cycles in our center performed from June 2010 to May 2015 and resulted in clinical intrauterine pregnancies were analyzed retrospectively. The predictive value was compared betweenβ-hCG on day 14 after cleavage ET andβ-hCG on day 12 after blastocyst ET.[Results]Serumβ-hCG levels of patients re?sulted in clinical intrauterine pregnancies were significantly higher with blastocyst ET compared with cleavage ET. This significant dif?ference was also existed in patients resulted in miscarriage, ongoing pregnancy (OP) or live birth (LB). However, this significant differ?ence was only existed in frozen embryo transfers. For a frozen cleavage ET, the cut-off value was 475 U/L (sensitivity 79%, specificity 61.3%) in predicting LB. For a frozen blastocyst ET, the cut-off value was 575 U/L (sensitivity 74.9%, specificity 59.2%) in predicting LB.[Conclusion]In frozen embryo transfers, early serumβ-hCG level after blastocyst ET is higher than cleavage ET. The cut-off val?ue in predicting pregnancy outcome is different according to the stage embryo transferred. Early serum β-hCG can effectively predict live birth after blastocyst or cleavage ET.

OBJECTIVETo investigate the association between two single nucleotide polymorphisms (SNPs), rs9390754 and rs4840200, in the glutamate receptor 2 (GRIK2) gene and the genetic susceptibility to epilepsy (EP) in the Han population in Central China.

METHODSA case-control study was performed in 284 EP children (including 132 children with refractory epilepsy) and 315 normal children from Central China. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine the genotypes of the two SNPs rs9390754 and rs4840200. The genotype frequency was compared between groups.

RESULTSThe frequencies of GG, GA, and AA genotypes of SNP rs9390754 showed a significant difference between the EP and normal control groups (P=0.016). The allele frequency also showed a significant difference between the two groups (P=0.002). The frequencies of CC, CT, and TT genotypes of SNP rs4840200 and allele frequency showed no significant differences between the two groups. The C allele frequency of SNP rs4840200 in the refractory EP subgroup was significantly higher than in the non-refractory EP subgroup (OR=1.435, 95% CI: 1.021-2.016, P=0.037).

CONCLUSIONSIn the Han population in Central China, the polymorphisms of SNP rs9390754 in the GRIK2 gene may be associated with EP susceptibility, and the C allele of SNP rs4840200 may be a genetic risk factor for the development of drug resistance in children with EP.
