Objective To investigate the inhibitory effect of synthetic interferon‐induced transmembrane protein 1(IFITM1) siRNA on the proliferation and migration of human ovarian cancer cell line CP 70 .Methods The siRNA targeted IFITM1 was transfected into CP70 cells by LipofectamineTM 2000 . Expressions of IFITM1 mRNA and protein were examined by qRT‐PCR and Western blot .Plate clone assay and Transwell chamber were used to observe the proliferation and migration of CP 70 cells .Results IFITM1 siRNA significantly inhibited the expression of IFITM1 in human ovarian cancer cell line CP70 at both mRNA and protein levels . The colony formation assay indicated that the clone number was 84 in IFITM1siRNA , which was much fewer than 181 in negative control group and 178 in mock transfection group .The colony‐forming efficiency (CFE) was 42% ,90 .5%and 89% ,respectively .Transwell chamber results showed that the number of migrated cells was 59 ,121 and 126 , respectively ;the siRNA transfection group differed significantly from the other two groups , indicating that downregulated IFITM1 expression greatly inhibited the proliferation and migration of CP 70 cells .Conclusion Knockdown of IFITM1 inhibited the proliferation and migration of CP70 cells .IFITM1 is a potential therapeutic target for human ovarian cancer .

This study was performed to investigate the chemical constituents in the twigs and leaves of Harrisonia perforate. Six compounds were isolated from the 95% EtOH extract of the twigs and leaves of Harrisonia perforate by silica gel, ODS, Sephadex LH-20 column chromatographies and preparative HPLC. On the basis of chemical properties and spectra data, these compounds were identified as harriperfin E (1), kihadanin A (2), kihadanin B (3), 6α-acetoxyobacunol acetate (4), gardaubryone C (5), and β-sitosterol methyl ether (6), respectively. Compound 1 is a new chromone, and compounds 2-6 are isolated from this plant for the first time.

OBJECTIVE: To analyze the characteristics in the incarcerated inmate's death, investigate the main cause of death of the incarcerated inmate and provide some information for forensic investigation. METHODS: The cases from the forensic medical center of Shanxi Medical University from 2005 to 2013 were selected. The statistical analysis was performed by using the incarcerated inmate's gender, age, cause of death, manner of death, and disease as the markers. RESULTS: There were 100 men, 5 women in the 105 incarcerated inmates; the age range was from 16 to 65 years; Inmates were mostly died of natural diseases, mainly in the respiratory and cardiovascular diseases; the main unnatural death was suicide with a rate of 54.5%. CONCLUSION At present, most incarcerated inmate's death are due to natural diseases. The prison should improve incarcerated inmate's lives, work and health care conditions, and strengthen supervision of law enforcement.

Objective To analyze the situation of smoking control calls at 12345 citizens′ hotline in Shanghai and investigate the smoking control hotspots concerned by citizens, the handling efficiency and quality of the hotline management, especially after the tobacco control ordinance was amended. Methods Statistical analysis was made on 48 945 smoking control calls, and data model established by natural language processing. Results After amendment of the tobacco control ordinance, there was a great increase in the number of smoking control calls, which reached a peak in 2017, and became 6.7 times that of 2016.Complaint report was the most important part of tobacco control calls, accounting for 76.24% of the total.Work and dining places were the main venue for complaints, while restaurants and offices were with the largest number of calls.The proportion of health departments in all responsible departments was the largest, accounting for 29.71%.Criticism and education were still the main way to deal with the problem, which was far from meeting the demands of citizens in this regard. Conclusion Publicity can mobilize the enthusiasm of the citizens to participate in tobacco control.The working efficiency and quality of responsible departments still needs to be improved.Citizen′s appeal can serve as a reference for future amendments to the law.

OBJECTIVETo observe the clinical significance of nitric oxide (NO) and 8-isoprostane (8-isoPG) changes in exhaled breath condensate ( EBC) of acute respiratory distress syndrome (ARDS) patients after treated by Qingfei Decoction (QD).

METHODSTotally 48 ARDS patients receiving mechanical ventilation were equally assigned to the QD treatment group and the control group by random digit table. EBC specimens were collected by modified Ecoscreen breath condensate collector (German JAEGER Company) on the first day and the fifth day after confirmed diagnosis of ARDS. Concentrations of NO and 8-isoPG in EBC were measured by ELISA. The oxygenation index and APACHE II scores were recorded at the same time.

RESULTS(1) The fatality rate in the QD treatment group was lower than that in the control group (8.3% vs 37.5%, P < 0.05). (2) After treatment NO and 8-isoPG concentrations in EBC were lower in the QD treatment group (34.49 ± 5.67 µmol/L, 30.09 ± 7.89 ng/L) than in the control group (39.78 ± 9.27 µmol/L, 35.65 ± 8.90 ng/L; P < 0.05). (3) After treatment improved oxygenation index value was higher in the QD treatment group than in the control group (120.88 ± 35.16 vs 101.50 ± 37.70, P < 0.05). After treatment APACHEII scores was lower in the QD treatment group than in the control group (6.21 ± 3.51 vs 10. 26 ± 4.33, P < 0.05).

CONCLUSIONTreatment of ARDS patients by QD was favorable in controlling inflammation, alleviating lung injury, and improving clinical efficacy.

Objective: To select the telomerase positive cancer cell lines of gastrointestinal tract and to provide a convinced methodology for future telomerase study. Methods: Fifteen cancer cell lines (carcinoma of stomach 4, of liver 6, of pancreas 2, of colon 3) were cultured and telomerase activity were detected by TRAP-ELISA. The normal hepatic cells were taken as control. Results: Thirteen cell lines were telomerase positive in the 15 lines(86.7%). Conclusion: Most of gastrointestinal tract cancer lines express telomerase, indicating the detection of telomerase activity has clinical potential.
