BACKGROUND: It has become a hot issue to treat malignant tumors with retroviral mediated cytokines. But it remains a controversy whether retroviral mediated γ-interferon(IFN-γ) is valid in killing glioma cells and prolonging the survival of tumor carriers.OBJECTIVE: To observe the effect of retrovital mediated γ-interferon on the growth of glioma and the survival of tumor-carrying rats.DESIGN: Completely ramdomized trial based on animals.SETTING: Neurosurgery department of a hospital affiliated to a university.MATERIALS: The trial was conducted in the Neurosurgery Institute of Harbin Medical Unicersity from July 2002 to July 2004. The subjects were 60 male Wistar rats provided by the Animal Center of the First Affiliated Hospital of Harbin Medical Unicersity. They were randomly assigned into 3groups: C6 control group, C6/PA317neo control group and C6/PA317IFN-γ treatment group, 20 in each group.INTERVENTIONS: Retroviral vector containing murine IFN-γ gene was transferred into retroviral package cell PA317. A high titer PA317IFN-γ cell line was obtained after G418 resistance screening. In the right basal ganglion area 1 × 106 C6 cells was injected in each of the rats. The rats in C6groups received no more intervention. Those in C6/PA317neo control group received injection of 1 × 106 PA317IFN-γ cells in the right basal ganglion 4days after C6 injection. Those in C6/PA317IFN-γ treatment group received injection of 1 × 106 PA317IFN-γ cells in the right basal ganglion 4 days after selected from each group to be kill, and the brains were taken out to make frozen sections for SABC immunohistochemical staining. The CD4 and CD8 T was measured with imaging processing software under microscope.RESULTS: The mean survival time of rats in C6 and C6/PA317neo control groups was(27.10 ± 0.82) days and (26.60 ± 0.93) days respectively( P ＞ 0.05), while that in treatment group was(49.30 ± 4. 17) days and there were five rats outlived beyond 60 days( P ＜ 0.01 vs the two controls). The tumor volume in the two control groups was of no difference but the tumor volume in treatment was significantly smaller than that in control groups( P ＜ 0. 01 ) . The CD4 and CD8 lymphocytes infiltration in treatment group was more than that in control groups( P ＜ 0.01) and there was no difference between the two controls( P ＞ 0.05) . It was also revealed through immunohistochemical examination that in treatment group there was Brdu positive cells on the 7th day and they disappeared on the 16th day. But there was no Brdu positive cells in the control groups.CONCLUSION: Intratumor injection of PA317IFN-γ induces anti-tumor immunal reaction in rats. Retroviral mediated IFN-γ inhibits tumor growth and prolongs rat survival.

Objective To explore the diagnosis and treatment of clinical possible organizing pneumonia.Methods The medical records of 31 patients with clinical probable organizing pneumonia were retrospectively analyzed.The clinical presentation,radiographic results and treatment were collected and analyzed.Results Thirty-one patients with non-response to antibiotics were preliminary diagnosed as organizing pneumonia.By percutaneous lung biopsy or transbronchial lung biopsy the tuberculosis,fungi,suppurative inflammation,lung cancer and other diseases were ruled out in 24 patients,and 7 patients were diagnosed by perfect effect of corticosteroids treatment.Twenty-one patients had typical CT findings.All the patients responded rapidly and completely to the administration of corticosteroids.Six patients relapsed after the reduction or stop of corticosteroid in a follow-up time of 6-25 months.Conclusions Non-response to antibiotics,the typical imaging findings and lung biopsy ruling out other diseases are important for diagnosing organizing pneumonia.Rapid response to administration of corticosteroids may be helpful to the diagnosis.Decreasing the dose of corticosteroid too early may cause recurrence of organizing pneumonia.

Objective To evaluate the reliability and validity of the Chinese version of the uterine fibroid symptom and health-related quality of life (UFS-QOL) in patients with uterine fibroid. Methods The original English UFS-QOL was translated into Chinese and linguistically validated following the cross-cultural adaptation of health-related quality of life measures. Patients recruited randomly from Peking Union Medical College Hospital from June 2013 to December 2016 were scheduled for two visits with 2 weeks apart, and they were surveyed through the Chinese version of UFS-QOL and short-form 12-item health survey (SF-12). The reliability and validity of the Chinese version of UFS-QOL were evaluated. Results A total of 190 uterine fibroid patients who met the criteria participated this study. The Chinese version of UFS-QOL had a high internal consistency (Cronbach′s α, uterine fibroid symptom severity scale:0.912, health-related quality of life scale: 0.976) and high test-retest reliability (intraclass correlation coefficient, 0.572 - 0.951, P<0.01). The symptom severity scores and SF-12 scores were negatively correlated (r=-0.813, P<0.01); the health-related quality of life scores and SF-12 scores were positively correlated (r=0.620, P<0.01). The factor analysis showed good construct validity. Conclusion Psychometric testing supports the reliability and validity of the Chinese version of UFS-QOL as an disease-specific measure of health-related quality of life.

This article was aimed to study the therapeutic effects and anti-inflammatory effects of Chinese and west-ern medicine ointment on fungal infection animals. Guinea pig models which were infected with Trichophyton rubrum or Microsporum lanosum were applied to observe the effects of antifungal infections on She-Zhi Qin-Xian (SZQX) ointment by transdermal administration. The ointment is the combination of miconazole nitrate, snake oil and Sophora flavescens which is traditional Chinese medicine (TCM). Simultaneously, the models of croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling were established to observe the curative effect of SZQX ointment. The results showed that the SZQX ointment had a protective role on both guinea pig models. The microscopic scale of localized lesions in infected guinea pigs was significantly decreased (P< 0.01). The effect of SZQX ointment was better than the single using of Chinese or western medicine. The SZQX ointment was also able to significantly reduce the croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling (P< 0.05, or P< 0.01) with distinct anti-inflammatory effect. And the effect of SZQX ointment was superior to the single using of either Chinese or western medicine. It was concluded that the SZQX ointment had significant antifungal infection and anti-inflam-matory effect.

Objective To explore the effect of electroacupuncture at Quchi (LI11), Zusanli (ST36) on differentiation of neural stem cells after cerebral ischemia-reperfusion in rats. Methods Thirty-six male Sprague-Dawley rats were randomly divided into sham group (n=12), model group (n=12) and electroacupuncture group (n=12). The latter two groups were occluded the left middle cerebral arteries for 90 min-utes and reperfused. The electroacupuncture group received electroacupuncture at Quchi and Zusanli acupoints for 21 days. They were evalu-ated with modified Neurological Severity Scores 7, 14 and 21 days after electroacupuncture. Their infarct volumes were tested with MRI T2WI 21 days after electroacupuncture, while the differentiation of neural stem cells was observed with double-immunopositive BrdU/Dcx and BrdU/NeuN. Results Compared with the model group, the neurological deficits score improved in the electroacupuncture group in all the time points (P<0.05). The infarct volumes decreased in the electroacupuncture group (P<0.05), with less number of BrdU+/Dcx+cells in subventricular zone (P<0.001) and more number of BrdU+/NeuN+ cells in peri-infarct cortex (P<0.001) 21 days after electroacupuncture. Conclusion Electroacupuncture at Quchi and Zusanli acupoints can improve neurological function and decrease the infarct volumes in rats after cerebral ischemia-reperfusion, which may be associated with promoting differentiation of neural stem cells to neurons.

This study aimed at analyzing the medication regularity based on differentiation in traditional Chinese medicine (TCM) for losing weight using text mining technique.All the references over losing weight were retrieved in CNKI,Wangfang Database,VIP Database and Pubmed.The drugs from the references were classified in accordance with drug property,drug flavor,channel tropism and drug efficacy.Frequency and constituent ratio of a single drug in TCM prescriptions for losing weight were put into analysis using chi square test and factor analysis to find out the medication regularity.It was found that the properties of TCM drugs in the prescriptions contained both cold and warm,while the flavors of the drugs involved pungent,sweet and light.The channel tropism of the drugs mainly belonged to spleen meridian,liver meridian,stomach meridian and lung meridian.They were mostly tonic,relieving,blood-activating,qi regulating,inhibiting-damp and antipyretic drugs.Through factor analysis we found that the common formula compatibilities were concluded as:cassia seed,lotus leaf,hawthorn,salvia miltiorrhiza,polygonum cuspidatum and radix polygonum multiflorum;capillary artemisia,epimedium herb,stephania tetrandra and ligusticum wallichii;dried tangerine peel,pinellia ternata and poria cocos;plantain seed,pericarpium arecae and selfheal;paeonia lactiflora,angelica sinensis,scutellaria baicalensis and ligusticum wallichii;poria cocos,cassia twig,atractylodes and glycyrrhiza;immature bitter orange and bark of magnolia;radix bupleuri,lycium chinensis and jujube;Chinese yam and coix seed;and astragalus,pueraria lobata and polygonatum.In conclusion,formula compatibility mainly combined syndrome differentiation with disease differentiation for the treatment of obesity in clinic,using the drugs belonging to liver meridian,spleen meridian,stomach meridian and lung meridian with the flavors of sweet,bitterness or pungent and the nature of both warm and cold.

Objective:To explore the association and gene-environment interaction between single nu-cleotide polymorphisms (SNPs)involved in cell-cell adhesion and non-syndromic cleft lip with or without cleft palate (NSCL/P)among Chinese population.Methods:A total of 806 NSCL/P trios were drawn by an international consortium,which conducted a genome-wide association study (GWAS)using a case-parent trio design to investigate genes affecting risks to NSCL/P.The transmission disequilibrium test (TDT)was used to explore the association between cell-cell adhesion genes,including CDH1,CT-NNB1,PVRL1,PVRL2,PVRL3,ACTN1,VCL,LEF1,and NSCL/P.Conditional Logistic regression models were used to estimate effects on risk of exposed and unexposed children.Four common maternal exposures including maternal smoking,environmental tobacco smoke,alcohol consumption and multivita-min supplementation during pregnancy were included in this study.Results:A total of 226 SNP markers were tested after quality control in this study.Although 23 SNPs in three genes (CTNNB1,CDH1, ACTN1)showed nominal significant association with NSCL/P in the TDT (P <0.05).There were no sig-nificant evidence of linkage and association that remained in the transmission disequilibrium test after Bonferroni correction(P >0.000 2).Tests for gene-environment interaction yielded significant results be-tween rs7431 27 in ACTN1 and environmental tobacco smoke (P =0.000 1 )with an estimated OR (case |G and E)=2.00(95%CI:1 .23 -3.26)and OR (case |G no E)=0.59 (95%CI:0.38 -0.90).Among the lower P value results in gene-environment tests,there were no significant results be-tween rs1 475034,rs370535,rs227341 9 in ACTN1,rs1 06871 in CTNNB1 and environmental tobacco smoke interaction.There were also no significant results between rs7634000,rs2971 366,rs2634553, rs1 489032,rs762481 2 in PVRL3 and multivitamin supplementation during pregnancy in gene-environ-ment tests(P >0.000 2).Conclusion:There is no association between cell-cell adhesion genes,inclu-ding CDH1,CTNNB1,PVRL1,PVRL2,PVRL3,ACTN1,VCL,LEF1,and NSCL/P when the genes are considered alone.But our results suggest that SNPs in ACTN1 may influence the risk to NSCL/P through gene-environment interaction.
