Objective To explore the effects of patient participation-based dietary intervention on nutritional status for patients with gastrectomy.Methods Fifty-two patients with gastrectomy were randomly assigned to the intervention group(n=26) and the control group(n=26).All patients were given general dietary guidance,and patients in the intervention group were provided patient participation-based dietary intervention(PPDI) as well.Height,body weight and body mass index(BMI) were recorded at baseline,2 weeks and 12 weeks after intervention,using PatientGenerated Subjective Global Assessment(PG-SGA),Diet-Related Symptom Scale,Adherence to Dietary Scale and a 3-day food diary.Results There was no obvious change in body weight and BMI before and after 12-week intervention,while outcomes in the control group gradually decreased.For time effect,there was significant difference in PG-SGA between two groups(P＜0.05).For between-group effect,there were significant differences in diet-related symptoms(P＜0.05),dietary intake(P＜0.05) and adherence to dietary(P＜0.05) between two groups.Conclusion Patient participation-based dietary intervention can improve nutritional status for patients with gastrectomy.

Objective To compare the isometric muscle strength of muscle groups in the lower extremities of children with spastic hemiplegia among sides or ages. Methods17 spastic hemiplegic children were measured the muscle strength of hip, knee and ankle muscle groups with hand-held dynamometry (HHD). ResultsMuscle strength was weaker in the involved side than in the other side. In younger children, it was weaker of overall extremity, while in the older it was of the distal end mainly. ConclusionWhen applying strength training to spastic hemiplegic children, it is important to notice strength of all groups in lower extremity in younger children and the distal groups in older ones.

Objective To understand the effect of butylbenzyl phthalate(BBP) on the levels of DNA-protein crosslinks(DPC) in hepatic cells of mice.Methods Twenty-five male Kunming mice were randomly assigned into five groups(n=5).BBP was administered by intraperitoneal injection at doses of 0(control group),125,250,500,1 000 mg/kg respectively for 14 consecutive days.Then the levels of DNA-protein crosslinks were detected.Results DPC coefficient increased with concentration of BBP increasing.Treatments of 500 and 1 000 mg/kg BBP significantly increased the levels of DPC compared with the control group. Conclusion BBP can not cause DPC at low levels(125 mg/kg),but it can cause DPC significantly at high levels(500 and 1000 mg/kg),which may cause serious DNA damages.

Recently,to assess the reproductive effects of bisphenol A (BPA),the environmental estrogen,has become a focus of stusy. Investigations,to date,have focused on the effects on the reproductive system including the morphogenesis of tissues and organs,endocrine and the toxic mechanisms of action,particularly in males. Based on the study results concerning BPA’s impacts on male reproduction,the further study directions in this field were presented in this paper.

Objective To investigate the relationship between tumor metastasis-related Rac1 mRNA expression levels and gastric carcinomas metastasis, and to investigate the significance of Rac1 as a tumor marker for the evaluation of gastric carcinomas metastasis and distinguish between benign and malignant lesions. Methods This experiment used fluorescence quantitative RT-PCR TaqMan probe technology, chose Rac1 target gene fragment, which was cloned into the pET-20b (+) vector, constructed recombinant plasmid, and established the Rac1 mRNA fluorescence quantitative RT-PCR standard curve. And then the Rac1 mRNA levels were detected in 52 cases of gastric carcinoma tissues,52 cases of para-carcinoma tissues and 12 cases of benign gastric disease tissues. Its association with the metastasis of gastric carcinomas was analyzed. Results The positive rates and levels (median, P25-P75) of Rac1 mRNA were 100. 0% ,7.41 ×105 (3. 50 × 105-4. 36 × 106) copies/μl in gastric carcinomas, 46. 2% ,0(0-1.73 × 104) copies/μl in parscarcinoma tissues, 33. 3%, 0(0-3.55 × 103) copies/μl in benign tissues. The positive rates and leves(x2 =43.16,x2Xk-w = 64. 19, P ＜0. 01)among the three groups were significantly different. When the critical value of Rac1 mRNA level was 1.73 × 104 copies/μl determined by ROC, the sensitivity and specificity were 88. 5% and 100% respectively. When the critical value of Rac1 level was 7.49 × 105 copies/μl, the sensitivity and specificity were 57.9% and 78. 6% respectively. ConclusionThe Rac1 mRNA level detected with fluorescence quantitative RT-PCR has reference value to distinguish between benign and malignant lesions and evaluate gastric carcinoma metastasis.

The clinical data of a case of Weave syndrome admitted in the Department of Endocrinology, Children′s Hospital of Nanjing Medical University in October 2018 were retrospectively analyzed.The patient was a 9 years and 2 months old girl, who was hospitalized because of " growing too fast for 9 years" . After birth, the child is found to grow fast and have mental retardation, slurred speech, a blurred vision, a long face, a protruding forehead, ocular hypertelorism, epicanthus, nasal bridge pit, finger pads on both hands and feet, uncoordinated gaits, and intoeingpigeon toes.A novel heterozygous c. 1720A>G (p.K574E) mutation was detected in the exon 15 of the EZH2 gene of the patient.This mutation has not been reported at home and overseas.Sanger sequencing revealed that the patient′s parents did not carry the mutation.The disease is an autosomal dominant genetic disorder, and the parents and sibling of the patient have no corresponding symptoms, so it is inferred that the mutation is spontaneous.Based on the peculiarity of the face, clinical manifestations and the results of molecular genetics, the child was diagnosed as Weaver syndrome.

A case with the diagnosis of the onset of inflammatory bowel disease (IBD) with chronic granulo-matous disease (CGD) in Children′s Hospital Affiliated to Zhengzhou University in June 2016 was chosen, and the patient′s clinical data and whole treatment process were analyzed.According to the relevant literature from Chinese and foreign databases, the clinical characteristics were analyzed and summarized, principles of diagnosis and treatment for children who had the onset of IBD with CGD.This patient was a child of 1 year and 9 months old, and the initial symptoms included repeated diarrhea and bloody stools.He was diagnosed as " ulcerative colitis" in the local hospital.After admission, the neutrophil respiratory burst test was positive.The genetic analysis result suggested that the CYBB gene was mutated, thus obtaining the diagnosis of CGD.Then, he was given prophylactic antibiotic therapy and symptomatic treatment.After the 3 months of follow-up after discharge, the patient still had intermittent diarrhea and bloody stools.CGD is a rare primary immunodeficiency disease, and current treatment methods of CGD include hematopoietic stem cell transplantation and anti-infection treatment.When IBD patients have complications other than gastrointestinal symptoms, the IBD treatment is not effective, or there are suspected parents who are married to close relatives, or with the family history of IBD, CGD should be considered.

Aurora-B as an important kinase to adjust the cell normal mitosis is a potent target for cancer treatment. Aurora-B is overexpressed in a broad range of tumor and tumor cells are more sensitive while Aurora-B is inhibited. Due to the key role of the Aurora-B in cell mitosis, the development of its inhibitors is becoming more and more important. Several small molecules inhibit with a similar efficacy both Aurora-A and Aurora-B, however, in most cases the effects resemble Aurora-B disruption by genetic methods, indicating that Aurora-B represents an effective therapeutic target. There were several Aurora-B kinase inhibitors which had entered the clinics and displayed good antitumor activity. In this review, we will outline the functions of Aurora kinase B in normal cell division and in malignancy. We will focus on recent preclinical and clinical studies that have explored the mechanism of action and clinical effect of Aurora-B inhibitors in cancer treatment.
