Novel targeted drugs and clinical trails have become the research highlights of non-Hodgkin lymphoma (NHL) recently. With further studies on immunotherapy in NHL, a number of novel immunotherapeutic targeted agents have been developed, some of which also had showed clinical benefit in early-stage study. The advances on novel immunotherapeutic targeted agents in NHL will be comprehensively reviewed in this paper from three aspects, including the targeted monoclonal antibody of cell surface antigen, the targeted therapy of cell signal transduction pathway and lymphoma microenvironment.

AlM: To study the relationship of retinal associated lesions and postoperative visual acuity of cataract phacoemulsification.
METHODS:From February 2013 to February 2014, 120 cases with given cataract phacoemulsification were divided into observation group and control group. Cases in observation group were with of retinal associated lesions, those in control group were without retinal associated lesions. The best corrected visual acuity, ision acuity, visual evoked potential, intraocular pressure were compared between two groups.
RESULTS:Two weeks after surgery, visual acuity in observation group was higher than those of before therapy. Visual acuity recovery rate of observation group was significantly slower than that of control group; best corrected vision, visual acuity in observation group was significantly lower than that in control group;observation group's amplitude (12. 01±4. 50ü V) was significantly lower than control group, incubation period (114. 29±11. 32ms) was significantly higher than control group; After 6, 12, 24h, intraocular pressure (23. 64 ± 4. 28, 24. 12 ± 5. 13 and 18. 28± 3. 22mmHg) were significantly higher than control group.
CONCLUSlON: Retinal associated lesions can lead to visual evoked potential change, elevated lOP, affect postoperative visual recovery level.

Objective To establish a rapid assay for genotyping of IL-6-597G/A and-572G/C polymorphisms by duplex real-time PCR assay.Methods One pair of primers and two pairs of fluorescent hybridization probes had been used to genotype two mutation sites in the promoter region of IL-6 gene by fluorescent resonance energy transfer and melting curves.Results Duplex real-time PCR method for genotyping of two mutation sites simultaneously had been developed and 123 health people samples were analyzed by this new method.The results showed that three genotypes were found in IL-6 gene-572G/C polymorphisms.They were GG,GC and CC genotypes.IL-6 gene promoter-597G/A polymorphism analysis showed 4 cases displayed GA genotype and other possessed GG genotype.No AA genotype had been found.Conclusions Duplex real-time PCR method is simple and fast.It provided an accurate and economic method which is suitable for clinical gene genotyping.

ObjectiveTo study the mechanism of differentiation of mesenchymal stem cells(MSCs) into neuron-like cells in vitro.MethodsMSCs of Wistar rats were separated and cultured, and then induced with DMSO and BHA in vitro. The specific marking proteins of neurons, glia and neural stem cells were detected before preinduction, at 24h after preinduction, at 6h, 24h, and 48h after neuronal induction.ResultsAfter the inducement, many MSCs turned into bipolar,multipolar and taper,and then intersected as network structure. Nestin was strong positive at 6h after neuronal induction, and decreased at 24h, 48h after the induction. NeuN was present at 6 h after neuronal induction, and increased at 24h, 48h after the induction.ConclusionMSCs can be induced into neural stem cells(NSCs) at first, and then differentiate into neuron-like cells in vitro.

OBJECTIVE: To evaluate and compare outcomes effects of Chinese recognition materials in post-lingually deafened patients with cochlear implant. METHOD: Thirty-two post-lingually deafened cochlear implant users participated in the study. Each one of them was given a series of speech recognition tests including the speech recognition score of monosyllable words, spondee words, Chinese BKB sentences and MHINT in quiet, as well as speech recognition threshold of HOPE corpus in babble noise. Speech recognition scores and thresholds were compared among these test materials using histograms , scatter diagrams and statistical methods. RESULT: Recognition scores for spondee words, Chinese BKB sentences and MHINT were affected by ceiling effects, with 1,14 and 4 cases scored 100% respectivelty. Meanwhile, 17, 26 and 14 cases scored more than 85% correspondingly. On the other hand, speech recognition scores for monosyllable words in quiet and speech recognition threshold for HOPE corpus in babble noise were not affected. CONCLUSION For a considerable part of post-lingually deafened patients using cochlear implant, some Chinese speech recognition materials have demonstrated different degrees of ceiling effects. While speech recognition scores for monosyllable words in quiet and recognition threshold for HOPE corpus in noise can evaluate the performance of speech recognition abilitymore objectively.

Objective To investigate the life quality in infants with food allergy before and after treatment by using of Food Allergy Quality of Life Questionnaire - Parent Form(FAQLQ - PF). Methods The severity of eczema in 46 children with food allergy was determined by eczema area and severity index(EASI). The life quality of such infants was assessed by the FAQLQ - PF after 2 - months treatment. Results (1)Among the 50 subjects,46(92% )respon-ded to the tests;the average age was(4. 78 ± 1. 48)months. Twenty - nine(63. 04% )subjects had family history of allergic disease. Egg(73. 91% )was the most common allergen,followed by cow milk(43. 48% ),fish and shrimp (8. 70% ),and carrot(4. 35% ).(2)The scores of EASI,FAQLQ - PF in children with food allergy before treatment were 13. 20 ± 12. 86 and 2. 12 ± 1. 33,respectively,the scores after treatment declined(2. 02 ± 4. 40 and 1. 33 ± 1. 08, respectively),there was a statistical significance(t = 28. 070,4. 014,all P ﹤ 0. 05).(3)Compared with pre - treat-ment,the scores of emotional impact subscale and food anxiety subscale declined,from 2. 10 ± 1. 47 and 2. 63 ± 1. 83 to 1. 30 ± 1. 09 and 1. 68 ± 1. 37,respectively,and there were statistically significant differences(t = 5. 204,8. 818,all P ﹤ 0. 05).(4)There was a positive correlation between the EASI and FAQLQ - PF scores(ρ = 0. 205,P ﹤ 0. 05). Conclusions Food allergy adversely affects the quality of life in infants. The poor life quality is associated with more severe symptoms. The life quality in infants and parents can be improved by standardized treatment.

Objective To explore the protective effect of astragalus injection(黄芪注射液)on cerebral cells after craniocerebral injury.Methods Sixty male Sprague-Dawley(SD)rats were randomly divided into five groups(each n=12).In the control group,only anesthesia and cranial bone surgery was performed, which did not impact on dura mater.In the model group,a freefall method was used to cause the left parietal lobe of brain limited contusion and saline was given.In the low,medium and high-dose astragalus injection (5,10,20 ml/kg)treatment groups,astragalus injection was injected intraperitoneally after injury at 30 minutes and 12 hours after injury respectively.After 24 hours of injury in each group,the rats were executed.The brain tissue from contusion was taken out and content changes of Ca~(2+),Mg~(2+),glutamate (Glu)and plasma endothelin(ET)were measured.Results In the model group,the Ca~(2+),Glu and ET contents in the rat brain tissues were significantly higher,but Mg~(2+)content was markedly lower than that of the control group(all P0.05).Conclusion Astragalus has a protective effect on nerve cells after craniocerebral injury.

Objective To investigate the efficacy and clinical effectiveness of the steroid therapy with the all body and local application on hyperthyroid Graves ophthalmopathy.Methods A total of 57 patients (106 eyes)suffering from hyperthyroid Graves ophthalmopathy who hospitalized in the Department of Ophthalmology of the Second Affiliated Hospital of Harbin Medical University from Mar 2008 to Oct 2011 were enrolled in the study.Of the 57 patients,there were 21 males and 36 females,aged 18 to 57(average 37.28 ± 11.63).The clinical course was from 1 month to 5 years(average 29.63 ± 15.36 months).Based on the patient's age,sex and condition,the 57 patients were randomly divided into steroid pulse therapy with all body group(group SPT,29 patients,54 eyes)and peribulbar injection of long-term steraid group(group PI,28 patients,52 eyes).The patients in group SPT were treated with 0.5-l.0 g methylprednisolone by intravenous infusion daily for 3 days,and then stopped for 7 days,the treatment was repeated once.But the total application dose of methylprednisolone was not overruned 5.0-20.0 g.After that,the patients were treated with oral prednisone 40 mg/d.The dose of prednisone was reduced gradually to 5 mg/d.The total course of group SPT was 3 months.The patients in the group PI were treated with triamcinolone acetonide in periorbital injection of 20 mg once every two weeks for 3 months.After one month treated,all patients were visited.The patients' body weights of two groups were measured before the treatment and after one month treated.The ocular signs of the patients including visual acuity,diplopia,intraocular pressure,exophthalmos and horizontal visual palpebral fissure width were observed before and after the treatment.Results In the group SPT,the average body weight [(62.83 ± 7.23)kg]after the treatment was higher than that before the treatment[(57.03 ±7.13)kg],and also higher than that of the group PI[(59.89 ± 10.67)kg,t =25.25,2.08,all P＜ 0.05]after the treatment.In the group SPT,the average intraocular pressures before and after the treatment were (13.46 ± 1.78)and (13.69 ± 1.41)mm Hg(1 nm Hg =0.133 kPa),respectively.In the group PI,the average intraocular pressures before and after the treatment were (13.52 ± 2.19) and (13.77 ± 2.03)mm Hg,respectively.There was no significant differences before and after the treatment in both gr0ups(P＞ 0.05).In the group SPT and PI,the average exophthalmos after the treatment[(18.63 ± 2.22) and (14.85 ± 2.61)mm]were lower than those before the treatment[(20.78 ± 2.24) and (20.60 ± 2.81)mm,t =9.97,29.68,all P＜ 0.05],respectively.After the treatment,the average exophthalmos in the group PI was significantly lower than that of the group SPT(t =7.79,P＜ 0.05).In the groups SPT and PI,the average averagepalpebral fissure width after the treatment[(15.00 ± 1.80) and (11.65 ± 2.45)mm]were lower than those before the treatment[(17.22 ± 1.89) and (17.44 ± 2.37)mm,t =22.74,91.24,all P ＜ 0.05].After treatment of the group PI,the average exophthalmos was significantly lower than that of the group SPT(t =8.01,P ＜ 0.05).Conclusion Compared with the steroid pulse therapy with all body,the peribullbar application of long-term hormone for hyperthyroid Graves ophthalmopathy is more effective,with lcss side effects and worthy of promotion.

BACKGROUND: Silk fibroin derived from silk had a good biocompatibility and biodegradation, which could be used for biomaterials to improve cell adhesion and growth abilities. OBJECTIVE: To investigate the efficacy of silk fibroin/hydroxyapatite (SF/HA) compounded of adipose-derived stromal cells (ADSCs) on repairing bone defects. METHODS: Adipose tissues were derived from epididymis of 2-month-old New Zealand rabbits and trypsogen-passaged to obtain ADSCs. The third-passage ADSCs at the concentration of 1×10/L were placed on SF/HA scaffold. Three hours later, the composite was cultured with DMEM culture media containing 1 μmol/L dexamethasone, 50 μmol/L vitamin C, and 10 mmol/L β-sodium glycerophosphate. Thirty-six rabbits were induced cancellated bone defect sizing 4.5 mm × 4.5 mm × 10 mm. The composite group was implanted with SF/HN/ADSCs scaffold, the simple group was implanted with SF/HA scaffold, but any treatment was employed in the blank control group. RESULTS AND CONCLUSION: At 12 weeks, general observation demonstrated that the bone defects were repaired entirely in composite group and partly in simple group. However, the bone defect was not repaired in the blank control group. X-ray and histological observation suggested that at 12 weeks the bone defects were repaired entirely in composite group and partly in simple group. The quantity of the newly formed bone in the composite group was significantly more than that in the simple group (P < 0.05). Repair showed no effect in the blank control group. SF/HA/ADSCs composite could successfully repair bone defects of a rabbit femur, and the effect was superior to SF/HA scaffold.
