To investigate the pathogenic mechanism of interleukin 6(IL-6) in the tubulointerstitial lesions of patients with active lupus nephritis(LN). Methods Uninary IL-6 from 42 active LN cases and the renal tissues sections from 15 of them were examined by performing ELISA and in situ hybridization with IL-6 cDNA probe labelled by digoxingenin respectively. Results In 36/42 (85.7%) of active LN patients, uninary IL-6 content was higher than or equal to 5 pg/mg ,cr, while no one case did in normal controls. Uninary IL-6 content was highly correlated with the uninary ft-m and NAG excretion respectively. In normal tubules and interstitium, IL-6 mRNA was undetectable. For all sections from 15 active cases, IL-6 mRNA was found in tubular and interstitial cells, and the distribution correlated with the extent of tubulointerstitial lesions. Conclusion IL-6 is probably involved in tubulointerstitial lesions of patients with active lupus nephritis.

The relationship of the nose tip position and the skull figures which were measured from the lateral craniographs in 49 ladies of 17～19 age living in Shenyang was studied. The figures measured on craniographs were analyzed by multiple stepwise regression analysis on IBM-PC/XT computer, and the regressoin equations for estimating the nose tip position of female in Shenyang were obtained. Cases in which the errors were within 2 mm were 71.43 to 77. 55 percent.

Objective To investigate the influence of mental intervention on the self-image of breast cancer patients.Methods Fifty patients with breast cancer who were hospitalized in our hospital from January to September,2015 were enrolled as the control group in the study,where routine nursing intervention,health education on disease related knowledge and psychological nursing were carried out.During October 2015 to June 2016,50 patients with breast cancer were enrolled as the observation group,where psychological awareness intervention was carried out apart from the routine nursing intervention.The self-image level of breast cancer patients from the two groups was evaluated by self-image questionnaire for breast cancer patients (BIBCQ).Result After intervention,the scores on self-image in the observation group were significantly higher than those in the control group (P＜0.05).Conclusion Mental intervention can improve the self-image of breast cancer patients and help improve their quality of life.

[Objective]To explore effect of polypeptides from chlamys farreri(PCF) on human umbilical cord blood cells(HUCBCs) differentiation in vitro,the effects of the extract on protein tyrosine kinase(PTKs) was studied in vitro.[Method]Getting human umbilical cord blood cells and cultured with the PCF at dilution concentrations of 1:1600,1:3200,1:6400,1:12800 nerve growth factor(NGF) was used as positive control and DMEM as negative one.After 48,72,96 h,the HUCBCs was cultured and the activity of protein tyrosine kinase(PTK) was examined by ATP in corporation test using PtK assay system.[Result]HUCBCs in the negative control group had no PTK activity,but that of positive control group was detected significantly.The PTK activity in extract of polypeptides from chlamys farreri groups increased at 48h(P

Objective To evaluate the diagnostic value of thinprep cytologic test (TCT) combined with high-risk human papillomavirus (HR-HPV) DNA for cervical cancer (CC). Methods 141 cases of patients with abnormal cervical lesions were abnormal examined by TCT and were graded by the results of TCT and cervical biopsy, the HR-HPV-DNA was detected by surface plasmon resonance (SPR). Results The cervical biopsy positive rate 65.2% (92/141) was significantly higher than the positive rate of TCT 39.0% (55/141) (χ2=19.45, P < 0.05). The positive rate of HR-HPV-DNA was 66.0% (93/141) was significantly higher than the positive rate of TCT 39.0% (55/141), (χ2=20.53, P < 0.05). Conclusion TCT, HR-HPV-DNA and cervical biopsy are important clinical diagnostic methods for cervical lesions, combine detection of TCT and HR-HPV-DNA can improve the detection rate of cervical lesions.

Objective To study the effect of external application of Wuwei Shuangbai Powder on relieving primary liver cancer pain and to observe its effect on hemorheology indexes.Methods A double-blind,randomized and controlled trial was carried out in 60 primary hepatocellular carcinoma patients with cancer pain.The patients were divided into control group and treatment group,30 cases in each group.The treatment group was given external application of Wuwei Shuangbai Powder and oral use of placebo capsules,and the control group was given external application of placebo powder and oral use of celecoxib capsules.The treatment for the two groups lasted for 7 days.Before and after treatment,pain was scored by Numeric Rating Scale (NRS),and the peripheral blood hemorheology indexes of both groups were observed.Results (1) After treatment,the NRS pain scores of both groups were decreased compared with those before treatment (P ＜ 0.05 or P ＜ 0.01),and the scores of the treatment group were significantly lower than those of the control group (P ＜ 0.05),indicating that the treatment group had better effect on relieving cancer pain.(2) After treatment,the indexes of hemorheology of treatment group were significantly higher than those of the control group,and the differences of the indexes except the hematocrit were significant between the two groups(P ＜ 0.05 or P ＜ 0.01).Conclusion Wuwei Shuangbai Powder is effective for the treatment of primary liver cancer pain.The mechanism may be related to the improvement of hemorheology of liver cancer patients.

In addition to kill tumor cells through direct cytotoxicity, the immunomodulatory activity is another facet of chemotherapy. The major molecular mechanisms of immunogenicity of cytotoxic drugs are elimination of CD_4~+ CD_(25)~+ regulatory T cells or Myeloid-Derived Suppressor Cells, and sensitization of tumor cells to immune effectors through modulation of death receptor expression. These studies provide scientific evidence for combinatorial treatments including vaccines and Traditional Chinese Medicine for cancer therapy.

OBJECTIVE: To observe the effects of ginkgolide (GL) on the cerebral blood flow in dogs. METHODS: Dogs anesthetized with sodium pentobarbital were randomly divided into 5 groups, with 4 dogs in each group. Ginkgolide of 4.86, 14.6 and 43.7 mg/kg and Xingling Granule of 0.22 g/kg were administered by gavage to the dogs in each of 4 groups. The dogs in the other group were administered with edible oil (1 ml/kg) as control group. The cerebral blood flow, systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and electro-cardiogram of the dogs were measured at different times after the administration. RESULTS: Ginkgolide of 4.86, 14.6 and 43.7 mg/kg had no obvious effects on the blood pressure and the heart rate. Ginkgolide of 14.6 and 43.7 mg/kg increased the cerebral blood flow 90 minutes after administration, and ginkgolide of 43.7 mg/kg obviously decreased the cerebral vascular resistance 150 minutes after administration. CONCLUSION: Ginkgolide can increase the cerebral blood flow and decrease the cerebral vascular resistance, and it has no obvious effects on blood pressure and heart rate in dogs.

The electrochemical behaviors of parathion(PT) on nano-Al2O3 film modified electrode(nano-Al2O3/GCE/CME) were investigated. It was found that the redox peak currents of PT remarkably increased and the oxidation peak potential negatively shifted at the nano-Al2O3/GCE/CME. All the experimental parameters were optimized and a simple and sensitive electroanalytical method was developed for the determination of PT. The oxidation peak current was linear with the concentration of PT over the range from 2.5×10-9 to 1.0×10-7 mol/L and 1.0×10-7 to 1.0×10-5 mol/L. A low detection limit of 1.0×10-9 mol/L was obtained for 30 s accumulation at open circuit(S/N=3). The relative standard deviation(n=10) was 3.8% for 1×10-5 mol/L PT. The proposed method was used for the quantitative analysis of PT in some vegetables and the results were satisfactory.
