Urine provides an alternative to blood plasma as a potential source of disease biomarkers. Exosomes was separated by ultracentrifuge at 200000 g in normal persons and non-small cell lung cancer (NSCLC) patients′ urine. For proteomic analysis of urinary exosome, 1D sodium dodecylsulfonate-polyacrylate gel electrophoresis(SDS-PAGE) was carries out and cut the gel 31 kDa-20 kDa bands in normal group and disease group′s. These gel blocks were subjected to in-gel trypsinization, and the extracted peptides were analyzed HPLC-CHIP-MS/MS. Approximately 24 unique proteins were identified in the UniProtKB/SWISS-PORT. The difference expression proteins were found in urinary exosome from NSCLC patients, including three fragment of the immunoglobulin kappa, two kinds of Ras related proteins, glutathione S-transferase A2, serum amyloid P-component precursor and phosphatidylethanolamine-binding protein 1.

ObjectiveTo assess the recent effect of the invasiveness and transsphenoidal microsurgical operation in the treatment of growth hormone-secreting adenom tumor.MethodsThe data of 22 patients with growth hormone(GH) adenomas were collected.All patients were tested preoperative GH level and that within the first 3 days,30 days following surgery.The invasiveness of pituitary adenomas was judged according to Hardy's classification scheme modified by Wilson.ResultsThere were 22 patients with GH-secreting pituitary adenomas,8 males and 14 females,11 patients with invasive adenomas and 11 patients with noninvasive adenomas.The remission rate between the patients with invasive adenomas and the patients with non-invasive adenomas had no statistically significant difference (P > 0.05 ).The postoperative remission rate of patients with GH values ≤ 50μg/L was no significantly lower than that of > 50μg/L( P > 0.05).ConclusionThe recent effects of operation were not significantly different with the invasiveness of tumor.

OBJECTIVETo develop a non-pharmacotherapy program for patients with hyperlipidemia and assess its effectiveness.
METHODSA cluster control trial was used. The experimental group was given non-pharmacotherapy for hyperlipidemia once a week for 6 weeks; the content of non-pharmacotherapy included the basic knowledge about hyperlipidemia, a guide of changing unhealthy diet and life-style. Patients were followed for once every two weeks in the department of out-patient. The control group received general care conducted by university clinicians, without the non-pharmacotherapy program. A self-completion questionnaire on hyperlipidemia-related knowledge level, questionnaires on diet and exercise, body weight, body height and the serum TG, TC were measured at entry point and at the end of 6 month.
RESULTSOne hundred and fifty-four patients in experimental group and 150 patients in control group completed the study. The non-pharmacotherapy group showed a significant increase of knowledge on hyperlipidemia in the experimental group comparing with the control group: the mean (sd) score of hyperlipidemia-related knowledge were 22.5 (4.8), 17.4 (4.2) (95% CI: 4.1, 6.1). The diet score and the proportion of regular physical activity had increased 27.20%, 21.78% respectively in experimental group. The mean (sd) of serum TG, TC and body mass index (BMI) for experimental group [2.0 (0.9) mmol/L, 5.4 (0.9) mmol/L, 23.4 (1.9)] lowered significantly comparing to those for control group [2.4 (0.9) mmol/L, 5.9 (1.0) mmol/L, 24.2 (3.0)].
CONCLUSIONNon-pharmacotherapy seemed to be an important intervention for the patients with hyperlipidemia. If same patients with hyperlipidemia failed to respond to non-pharmacotherapy, it is necessary to use pharmacotherapy. However, non-pharmacotherapy should be viewed as basic therapy.

Objective To compare the clinical effect of minimal invasive drilling cranium from frontal part and craniotomy from temporal in the treatment of patients with cerebral hemorrhage in basal ganglia.Methods From August 2011 to August 2017,126 cases with cerebral hemorrhage in basal ganglia in the People's Hospital of Meishan were divided into observation group and control group,with 63 cases in each group.The observation group was treated by minimal invasive drilling cranium,and the control group was treated by craniotomy.The clinical treatment effect,operation indicators (operation time,amount of intraoperative bleeding,operation cost,discharge time) and nervous function recovery were analyzed.Results The operation time,amount of intraoperative bleeding,operation cost,discharge time of observation group were (31.6 ± 10.3) min,(20.9 ±5.8)mL,(2.1 ± 1.0) thousand CNY,(15.3 ± 0.9) d,respectively,which were better than those of the control group [(214.2 ± 46.8) min,(94.1 ± 56.2) mL,(15.0 ±4.8) thousand CNY,(21.4 ±0.4)d] (t =13.56,11.94,19.65,8.39,all P <0.05).The effective rate and the nerve function score between the two groups had no statistically significant differences (all P > 0.05).Conclusion The minimal invasive drilling cranium from frontal part has advantages of small surgical trauma,short operation time,less bleeding in the operation,low death rate,less cost of operation,short hospitalization time and good drainage effect,and thus it is worthy of clinical application.

Objective To investigate the regulation effects of Ngn2 gene transfection on retinal neuron differnetion in three-dimentional optic vesicle (OV) of mice.Methods OV was cultured in vitro using mouse induced pluripotent stem cells (iPSC) under specific conditions.During OV culture,it was transfected multiple times by lentivirus-mediated Ngn2 gene and then it was induced after maturation.The cells were specificly differentiated toward retinal nerve cells in OV.Using the green fluorescent protein (EGFP) gene as control,the differentiation of retinal nerve cells in OV was detected by immunohistochemistry.Reverse transcription PCR and Western blot were used to quantitatively detect the expressions of retinal neuron-specific proteins Pax6,Islet1 and Brn3b.Results The mouse iPS-derived OV was successfully cultured.The number of neural cells in the OV transfected with the Ngn2 gene was increased by the lentiviral-mediated lentivirus.The expressions of PAX6,Islet1 and Brn3b in the Ngn2 transfection group were significantly higher at the gene and protein levels than those in the control group,with significant differences between the two groups (P<0.05).Conclusions The Ngn2 gene can effectively increase the number of retinal neuron differentiation in OV and make in vitro cultured OV more mature and form a more perfect retinal cell neural circuit.
