Fudan University Journal of Medical Sciences 2009;36(6):786-788
Radioimmunotherapy using monoclonal antibodies incorporated with radionuclide has been showed to be an effective agent for refractory non-Hodgkin's lymphoma (NHL). Many anti-CD20 antibodies labeled with radionuclide, such as 90Y-ibritumomab tiuxetan (Zevalin) and 131I-tositumomab tiuxetan (Bexxar), have been reported to be effective for the treatment of patients with relapsed or refractory low-grade, follicular, or transformed NHL. This review summarizes the current advance in clinical trials and studies of Zevalin and Bexxar for the treatment of NHL patients.

7.The application of fast track surgery theory in thoracoscopes pulmonary bulla resection
Chinese Journal of Postgraduates of Medicine 2017;40(1):40-43
Objective To explore the feasibility, safety and advantage of thoracoscopes pulmonary bulla resection without thoracic closed drainage tube according to the fast track surgery (FTS) theory. Methods The clinical data of 53 patients with pulmonary bulla were retrospectively analyzed. Among them, 29 patients underwent the thoracoscopes pulmonary bulla resection without thoracic closed drainage tube (FTS group), and 24 patients underwent the thoracoscopes pulmonary bulla resection with thoracic closed drainage tube (tradition group). The oxygenation index at 24 h after operation, visual analogue score (VAS) at 24, 48 and 72 h after operation, postoperative complications, postoperative hospital stay and hospital costs were compared between 2 groups. Results There was no statistical difference in oxygenation index at 24 h after operation between FTS group and tradition group:(312.4 ± 16.4) mmHg (1 mmHg=0.133 kPa) vs. (330.6 ± 13.2) mmHg, P>0.05. The VAS at 24, 48 and 72 h after operation in FTS group was significantly lower than that in tradition group:(2.6 ± 1.1) scores vs. (4.3 ± 1.6) scores, (1.6 ± 0.9) scores vs. (3.8 ± 1.4) scores and (0.8 ± 1.0) scores vs. (2.9 ± 1.4) scores, and there was statistical difference (P<0.05). The incidence of postoperative complications, postoperative hospital stay and hospital costs in FTS group were significantly lower than those in tradition group:13.8%(4/29) vs. 37.5% (9/24), (3.2 ± 0.9) d vs. (6.2 ± 1.2) d and (1.3 ± 0.3) × 104 yuan vs. (1.5 ± 0.4) × 104 yuan, and there were statistical differences (P<0.05). Conclusions FTS used in thoracoscopes pulmonary bulla resection is feasible and safe, and has certain advantages.

AIM: To investigate the situation of patients with mechanical ocular trauma and the possible influencing factors related to the prognosis.METHODS: Totally 260 patients(286 eyes) with mechanical ocular trauma from January 2011 to January 2016 in Xiaogan Central Hospital were selected and retrospective studied.Sociology and clinical data including gender,age,career,injury causes,injury nature,treatment time and visual acuity on admission in these patients were univariate analyzed,then the positive factors were analyzed using Logistic regression.RESULTS: The middle-aged and young males were domain in 260 patients.The causes were mainly sharp instrument injury,while perforating injury of eyeball was the majority in injury nature.Univariate analysis showed that injury causes,injury nature,treatment time and eyesight on admission were influencing factors,while multivariate analysis by Logistic regression showed that visual acuity on admission and orbital contusion were independent influencing factors for patients ocular trauma.CONCLUSION: Ocular trauma is a majoy cause of monocular blind,there are close associations between prognosis of ocular trauma and orbital contusion and visual acuity on admission.But the majority of ocular trauma is preventable and treatable,the relevant measures should be developed to prevent the ocular trauma.

AlM: To analyze the correlation between tear film changes of allergic conjunctivitis and dry eye, then provide clinical references for better treatment.
METHODS: Fifty patients with allergic conjunctivitis were taken as the observation group, the control group was selected based on 1:1 case control theory, and we chose 50 health volunteers without ocular surface diseases, xerophthalmia and systematic diseases randomly, then fluorescein ( FL) staining, break-up time ( BUT) , Schirner l test ( SⅠt) , tear meniscus high ( TMH) and slit-lamp examinations were performed in the two groups.
RESULTS: ln the observation group, FL, BUT, Slt, TMH of right eyes and left eyes were statistically significant correlated ( P < 0. 05 ). FL and BUT were statistically significant between control group and observation group (P<0. 05). TMH and Slt has positive correlation, while FL and BUT has negative correlation and the differences were statistically significant (P<0. 05). CONCLUSlON: Due to inflammatory mediators participation, allergic conjunctivitis could lead to the stability changes of tear film which cause in dry eye. The stability changes of allergic conjunctivitis correlate to the damage degree of epithelium.

OBJECTIVE:
To establish miniSTR fluorescent detection system with all detected fragments below 150 bp and to enhance the efficiency of detecting the degraded DNA samples.
METHODS:
All candidate primers were designed by Primer Premier 5 and screened by FastPCR 6.0. The miniSTR multiplex system was established by these selected loci labeling by four fluorescent dye. The parameters of PCR and primer concentrations were subsequently optimized. The electrophoresis was fulfilled under POP4 on 3100-Avant and the typing data was validated by standard DNA 9947A and 007. Fresh blood samples and difficult degraded DNA samples were tested to evaluate the usefulness of the system.
RESULTS:
All amplicons in the established miniSTR fluorescent detection system (D12ATA63, D2S1776, D1GATA113, D4S2408, D17S974, D20S482, D3S3053, Amelogenin, D6S474, D9S1122) were less than 150bp. The profile showed a balanced peak height without extra stutter by optimal protocol. Allele frequencies showed no deviations from Hardy-Weinberg equilibrium. The system showed accumulated probability of discrimination 0.999 999 983 and accumulated triplet excluding probability of paternity 0.996 8. It could detect corrupt muscle tissue, low copy number DNA samples and human tissues fixed by 40% formaldehyde solution for 12 days.
CONCLUSION
The miniSTR fluorescent detection system could be solely used for personal identification of degraded DNA samples or complementally used for paternity tests. And the system could enhance the ability of detecting the trace and degraded DNA.
