Interferons are potent cytokines with antiviral activity that have been founded earliest. Different types of interferons have similar bioactivity, Such as anti-viruses activity, anti-tumor activity and immune modulation. They are induced by virus infection and trigger the host defense by different mechanisms. Firstly, IFNs directly induce the expression of effector proteins with antiviral activity, thus establishing a first line of defense. Secondly, they help to shape adaptive immunity, leading to long-lasting protection. Due to the key position of IFNs in antiviral defense, viruses have evolved effective countermeasures in order to successfully invade the host. By expressing so-called IFN antagonists, viruses interfere with either IFN induction, IFN signaling, or the action of IFN effector proteins.

Objective To assess the efficacy and safety of intrapleural instillation of Yadanzi (Brucea Javan-ica)oil emulsion injection and cisplatin for malignant pleural effusion by literature searching and meta -analysis. Methods Databases were searched for random controlled trails (RCTs)including Pubmed,the Cochrane Library, CNKI,VIP,Wanfang Database and CBM.The quality of included RCTs was evaluated and the data were collected by 2 evaluators independently.Meta -analysis was performed using RevMan 5.2.Results 18 RCTs involving 1 322 par-ticipants was included.The results of meta -analysis indicated that intrapleural instillation of Yadanzi oil emulsion injection and cisplatin could improve the treatment efficiency of malignant pleural effusion (OR =3.82,95%CI 2.94 ~4.96,P <0.01)and improve the quality of life of patients(OR =4.07,95%CI 2.87 ~5.79,P <0.01),and reduce the gastrointestinal tract reaction (OR =0.55,95%CI 0.38 ~0.78,P <0.01)and white blood cell reduction occurs (OR =0.34,95%CI 0.25 ~0.46,P <0.01).Conclusion Intrapleural instillation of Yadanzi oil emulsion injection and cisplatin was effective and safe in the treatment of malignant pleural effusion,while the further studies should make efforts in improving research quality.

Objective To verify whether the storage bag can reach the use requirement of cord blood freezing storage by conduc-ting a series of tests before staring use of new type cryopreservation bag for cord blood.Methods According to the standard opera-tion procedure,28 new type cryopreservation bags were extracted.The cord blood units were performed the cryostorage and thaw for rewarming according to the standard operating procedures.Then the physical integrity and various quality indicators of cord blood in bag were detected,including the nucleated cell viability,cell recovery rate,CD34-positive cell,colony-forming cultivation of stem cells,sterility test and verification of actual load volume.Results All the tested storage bags passed the integrity test,and the various testing indicators of the preserved cells conformed to the use requirements.Conclusion The new type storage bag has the same performance and effect to original bag,it is verified that the maximum loading volume of 50 mL(for 50 mL specification of storage bag)and 80mL(for 250mL specification of storage bag)is safe.

OBJECTIVETo investigate the soft and hard tissue changes in Class II division 1 patients treated with Tip-Edge plus technique.

METHODSSixteen Class II division 1 patients (7 boys and 9 girls) with mandibular retrusion in permanent dentition were selected and treated with Tip-Edge plus appliance. Lateral cephalometric films were analyzed before and after treatment. The effects were evaluated with Holdaway soft tissues analysis and routine cephalometric analysis methods. The arithmetic mean and standard deviation were calculated for each variable. Paired t-test was performed.

RESULTSThe average treatment time was 16 months. Normal overjet and overbite were established with retroclination of upper incisors and proclination of lower incisors. U1-NA(°) and U1-NA (mm) decreaed by (15.40 ± 5.31)° and (4.16 ± 1.82) mm (P < 0.01). NLA showed an average increase of (-16.60 ± 5.29)° (P < 0.01). Remarkable soft tissue change was noted after the treatment.

CONCLUSIONSThe profile in Class II division 1 patients could be quickly and efficiently improved after treatment with Tip-Edge plus technique.

OBJECTIVETo study the chemical constituents of the twigs of Morus atropurpurea.

METHODThe compounds of the EtOAc fraction were isolated and purified by column chromatography on silica gel, polyamide, Sephadex LH -20, and their structures were elucidated on the basis of spectroscopic evidence (MS, NMR).

RESULTEleven compounds were identified as mulberrin (1), cyclomulberrin (2), morusin (3), cyclomorusin (4), 2', 4',4, 2"-tetrahydroxy-3'-{3"-methylbut-3"-enyl-}-chalcone (5), mulberrofran G (6), scopoletin (7), moruchalcone A (8), kaempferol (9), ursolic acid (10), beta-daucosterol (11).

CONCLUSIONExcept compounds 9 and 11, all the other compounds were obtained from M. atropurpurea for the first time.
