Objective To investigate the clinical significance of circulating tumor cells (CTCs) in pa-tients with small-cell lung cancer patients (SCLC). Methods 42 SCLC patients, 10 patients with benign lung disease(hospitalized from June 2012 to June 2013), and 10 healthy volunteers from the First Affiliated Hospital of Shihezi University Medical College were studied and their clinical information was collected. Negative immuno-magnetic separation method and immunocytochemistry method were applied to collect the Pan-CK +/CD45 - of CTCs, in order to analyze the relationship between CTCs and clinical manifestation. Results CTCs were found in 32 cases of SCLC group, with a positive rate of 76.19%. CTCs was not found in peripheral blood in control group. Difference in the two groups is significant (P = 0.000). The presence of CTCs was correlated positively with the patients′ PS score , clinical stage , M stage , the number of metastatic sites , NSE value and LDH value (P < 0.05). Conclusion The CTCs number is correlated with patients′ PS score, clinical stage, M stage, the number of metastatic sites, NSE value and LDH value, respectively. CTCs detection is useful for more accurate risk assessment of patients.

Objective To investigate the relationship between levels of transferring(Tf)and function of male fertility and testic-ular podocyte.Methods Semen samples from male patients with infertility and volunteers with normal infertility were collected and tested for sperm density and motility by using sperm quality analyzer.In additon to that,Tf concentrations of Tf were determined;aseptically excised rat testis and by collagenase and hyaluronidase digestion,podocytes were isolated with high purity and cultured in culture medium,then the concentration of Tf in cell culture medium was determined;Tf concentration were determined by rate nephelometry.Results Tf concentration in semen of male-infertility patients[(15±5)μmol/L]was significantly lower than that of normal-fertility volunteers[(24.5±6.5)μmol/L,P <0.01],which were positively correlated sperm count and motility(P <0.01). Tf concentrations of cell culture medium[(25 ±8)μmol/L]in which testicular podocytes were cultured were significantly higher than that of infertile rat[(15 ±6)μmol/L,P <0.01].Conclusion Determination of semen Tf levels can reflect podocyte function and be used as an indicator for the evaluation of seminiferous tubules spermatogenesis,which was valuable in the diagnosis and treatment of male infertility.

Background Recent studies have demonstrated that epicardial flow in nonculprit arteries,which has been assumed to be normal,was slowed in the setting of ST-elevation myocardial infarction (STEMI).However,the impact of primary percutaneous coronary intervention (PCI) on blood perfusion in nonculprit arteries in patients with STEMI has not been clarified.The purpose of this study was to investigate the impact of primary PCI on blood perfusion in nonculprit arteries in patients with STEMI and correlated clinical factors.Methods A total of 117 patients with anterior wall STEMI,the culprit artery being the left anterior descending artery (LAD),undergoing primary PCI (the study group) and 100 patients with normal coronary angiography (the control group) were enrolled.To observe the differences of corrected TIMI frame count (cTFC) and myocardial blush grade (MBG) before and after primary PCI in both culprit and nonculprit arteries,the left circumflex coronary artery (LCX),cTFC and MBG in the LAD and LCX were measured in the study group and control group.The study group was divided into three groups; reflow in the culprit artery group (the R group),no reflow in culprit artery group (the NR group),and no reflow in both the culprit artery and nonculprit artery group (the NRB group) according to MBG grade.The level of serum C-reactive protein (CRP),catecholamine,and fibroblast growth factor-21 (FGF21) were assayed.The clinical and angiographic characteristics were also analyzed.Results cTFC (28.1±24.3 vs.20.3±19.3,P ＜0.05) and MBG in the LCX were different in the study group compared to the control group before primary PCI.cTFC (25.2±22.3 vs.28.1±24.3,P ＜0.05) and the MBG level in the LCX were improved after successful primary PCI,but were not recovered to the normal level.Patients with no reflow in the culprit artery had a higher incidence of no-reflow in the nonculprit artery (78％ vs.19％,P ＜0.0001),and the levels of CRP ((3.29±1.31) mg/dl vs.(2.51±1.14) mg/dl vs.(2.93±1.07) mg/dl,P ＜0.05,respectively),catecholamine ((epinephrine (693.48±89.78) pg/ml vs.(398.12±93.28) pg/ml vs.(562.54±96.22) pg/ml,P ＜0.0001,respectively),and norepinephrine ((7012.43±932.47) pg/ml vs.(4012.34±814.16) pg/ml vs.(5549.03±912.65) pg/ml,P ＜0.0001,respectively)) in the NRB group were higher than those in the R group and NR group.The level of FGF21 ((0.299±0.093) ng/ml vs.(0.612±0.071)ng/ml vs.(0.428±0.074) ng/ml,P ＜0.0001 respectively) in the NRB group was lower than that in the R group and NR group.Conclusions The blood perfusion in the nonculprit artery may be impaired in patients with STEMI.Although nonculprit artery perfusion may be improved after successful primary PCI,it is still lower than that in the control group,and may be involved in inflammation and spasms.

AlM:To evaluate the efficacy of combined pranoprofen eye drops and artificial tears on the treatment of mild to moderate dry eye syndrome after trabbeculectomy.METHODS:This prospective case control study included 63 cases (63 eyes) of patients with mild to moderate dry eye syndrome after trabbeculectomy in our hospital from November 2013 to June 2013. All subjects were randomly divided into two groups. Observation group was treated with combined pranoprofen eye drops and artificial tears and control group received simple artificial tears marking the eyes at 1, 2, 4wk. The patient's symptoms, signs, BUT, S▏t, and FL were observed before treatment and 1, 2, 4wk after treatment.RESULTS: After 2wk, the symptoms of observation group were improved, there was statistically significant difference (P<0. 05). FL difference of each group was statistically significant ( P<0. 05 ); After 4wk, symptoms and signs were improved. There was statistically significant difference ( P < 0. 05 ). The BUT of the observation group and corneal FL scores of two groups showed significant differences (P<0. 05). CONCLUSlON: Artificial tears joint pranoprofen eye drops has good curative effect in the treatment of mild to moderate dry eye syndrome after trabbeculectomy.

OBJECTIVETo investigate the protective effect and action mechanism of petroleum ether extracts from Saussurea involucrate on brain tissues of hypoxia rats under constant pressure and closed conditions.

METHODThe PESI dosage-dependent experiment for hypoxia rats was conducted under constant pressure and closed conditions by intraperitoneally injecting 125, 250, 500 mg x kg(-1) to finalize that the optimum dosage is the high dose of PESI. Afterwards, 90 Wistar rats were randomly divided into the hypoxic model group, the acetazolamide 250 mg x kg(-1) group and the PESI high dose group. Each group was further divided into three subgroups according to different hypoxia times, with 10 rats in each subgroup. Under the same hypoxia and administration conditions, the rats were sacrificed after 0, 3, 6 h respectively. Their brain samples were collected for common pathological observation and immunohistochemical staining of HIF-1alpha. Real-time RT-PCR was used to detect HIF-1alpha, EPO, HO-1 and Caspase-3 gene expressions. And the Western blot assay was adopted to detect HIF-1alpha protein expression.

RESULTThe brain tissues of the hypoxia model group were severely damaged with the increase in the hypoxia time. The acetazolamide group and the PESI high does group were damaged in a much lower degree. According to the gene expression and the Western blot assay, high dose of PESI could inhibit HIF-1alpha expression. According to the pure gene expression test, high dose of PESI could increase EPO and HO-1 mRNA expressions, but inhibit Caspase-3 mRNA expression.

CONCLUSIONPESI's protective mechanism for brain tissues of hypoxia rats under constant pressure and closed conditions may be related to its effects in inhibiting HIF-1alpha expression, increasing EPO expression and resisting cell apoptosis.
