The same paraffin-embedded specimen of skin biopsy from each of 29 patients with cutaneous malignant lymphomas (CML) and 7 patients with cutaneous lymphoid infiltrates (CLI) was estimated simultaneously and retrospectively by karyomorphometry and proliferating rate assay. The results showed that the differences in nuclear volumes (NVs), count of argyrophilic nucleolar organizer regions(AgNORs) and proliferating cell nuclear antigen (PCNA-PC10) indices (PC10Is) between CML and CLI were statistically very significant. The NVs and PC10Is were correlated to the death rate of patients. NVs were also correlated to AgNORs.

BACKGROUND: As a multifunctional cell growth factor, vascular endothelial cell growth factor (VEGF) plays various biological roles under some physiologic and pathologic conditions. OBJECTIVE: To summarize molecular structure and biological effects of VEGF. RETRIEVAL STRATEGY: A computer-based online search of PubMed database was undertaken to identify related English articles dated from January 1989 to December 2007 with keywords"VEGF, molecular structure, biological effect, diabetes, diabetic macroangiopathy". 934 articles were firstly collected, including 38 about molecular structure and biological effects of VEGF, and 896 about diabetes and diabetic macroangiopathy. After the first trial, only articles about ①molecular structure and biological characteristics of VEGF, and ②diabetes and diabetes complicated by coronary heart disease or limb vascular disease were selected. 897 repetitive, outdated and unrelated articles were excluded. Finally, 35 articles were included. LITERATURE EVALUATION: Of 35 articles, there were 17 ones about animal trials, and in vivo, in vitro and cytological studies, 8 of review articles and comments, and 10 clinical studies. All articles were individual evaluation. DATA SYNTHESIS: Human VEGF genes consist of 8 exons and 7 introns, and are located in 6p21.3 region. VEGF encodes several isoforms with different biological characteristics. Two VEGF receptors display different biological effects. VEGF and its receptors are regulated by various factors. The receptors interact with ligand and play biological effect. In diabetic patients complicated by coronary heart disease, myocardial VEGF mRNA and protein expressions are increased but the expressions of two kinds of receptors are decreased compared with non-diabetic patients. Compared to patients with non-severe lower limb ischemia, VEGF production is more in diabetic patients complicated by severe lower limb ischemia. It is demonstrated that VEGF can restore injured neovascularization. However, VEGF therapy for diabetes still needs further study. CONCLUSION: VEGF can restore impaired neovascularization. VEGF expression shows diversity under diabetic macroangiopathy. Further study should be made focusing on the prevention value of VEGF to diabetic macroangiopathy.

Objective To investigate the olanzapine and quetiapine quetiapine in the treatment of Alzheimer's disease patients of different clinical effects and influence on the swallowing function of patient.Methods According to the order of visits to the author departments were 73 cases of Alzheimer's patients were divided into group A(37 cases) and group B(36 cases).Patients in group A were treated with olanzapine in the treatment of, and group B with quetiapine in the treatment, the time of the two groups of patients are 12 weeks, to observe the differences of the two groups during the treatment of swallowing function indexes and clinical efficacy.Results After treatment, the MMSE scores of two groups of patients compared with pre-treatment, there was no statistical significance and BEHAVE-AD score before treatment significantly decreased ( P <0.05 ).Post-treatment, the patients in two groups of MMSE, BEHAVE-AD score difference does not have statistical significance.The difference of clinical efficacy between two groups post-treatment was not statistically significant.Watian drinking water test score of two groups Post-treatment, SaO2 decreased value compared with those pre-treatment significantly increased (P<0.05).After treatment of two groups of patients Watian drinking water test score difference does not have statistical significance, and post-treatment, patients in group B of SaO2 decreased value lower than that in group A ( P <0.05 ).Mild dysphagia, two cases of moderate swallowing dysfunction occurred in twenty-six patients in group A, group B with mild swallowing dysfunction occurred in twenty-one patients, A group of swallowing dysfunction more serious than group B serious ( P <0.05 ) .Conclusion Olanzapine and quetiapine quetiapine in the treatment of patients with Alzheimer's disease clinical effect quite, patient's swallowing function cause some adverse effects, effects of olanzapine is more serious.

Objective To compare the effect of single-tube drainage with that of two-tube drainange in non-small cell lung cancer(NSCLC) patients with VATS upper-lobectomy.Methods Between August 2012 and August 2014,100 NSCLC patients who had received VATS upper-lobectomy performed by a single surgeon were prospectively enrolled and randomly classified into a single-tube drainage group(A) and a two-tube drainage group(B),consisting of 49 and 51 patients respectively.Upper-lobectomy and systematic mediastinal node dissection or sampling were performed in all cases.Clinical and surgical variables were collected prospectively.Results There were no significant differences in demographic and pathologic features between two groups.The amount/duration of drainage,the postoperative hospitalization days,postoperative morbidity and mortality between two groups showed no significant difference either.Group A patients had significantly lower VAS pain scores in the second day (4.06 ± 0.97 vs 4.47 ± 0.86,P =0.027) and one month after surgery (1.31 ± 0.68 vs 1.61 ± 0.64,P =0.024)compared with group B patients.Conclusion Single-tube drainage is as safe and effective as the conventional use of two-tube drainage after VATS upper-lobectomy in NSCLC patients.Moreover,single-tube drainage can relieve the post-operative pain for the patients.

Objective:To evaluate the effect of nutritional status on postoperative outcomes for patients with gastric cancer. Methods:Data of 353 gastric cancer patients at Xinjiang Medical University Affiliated Tumor Hospital between January 2013 and October 2014 were collected prospectively. Preoperative nutritional status was evaluated using Nutrition Risk Screening 2002 (NRS 2002). Postoperative complication rates were compared among different preoperative nutritional status. Results:On the basis of NRS 2002, the morbidities of patients with and without malnutrition risk were 47.0%(77/164) and 31.2%(59/189), respectively (P=0.002). Among the patients with an NRS score of at least 3, the complication rate was significantly lower in the group with preoperative nutrition than in the group of patients without preoperative nutrition support (P=0.013). NRS 2002 was a significant predictor of postoperative complications (P=0.039, OR=1.634, 95%CI:1.025-2.606) on the basis of multivariable logistic regression analysis. Conclusion:As a nutritional evaluation tool, NRS 2002 may predict postoperative complications for gastric cancer patients.
