International Eye Science 2015;(7):1201-1203
AlM: To learn the changes of the tear film before and after the trabeculectomy of glaucoma and explore the incidence of dry eye and the prevention and control measures.METHODS:The 36 patients (60 eyes) of glaucoma were examined in detail before 3d of trabeculectomy and after the surgery at 3, 7, 14 and 30d. The examinations include lower eyelid central river of tears, break-up time ( BUT) , Schirmer I test ( S I t ) and staining scores of corneal fluorescein under slit lamp microscope.RESULTS:The tear meniscus height of central lower eyelid was increased and the tear film BUT was shortened at the same time, the scores of S I t was reduced and corneal fluorescein staining score was increased at postoperative 3 and 7d compared with that of preoperation. The tear meniscus height of central lower eyelid, tear film BUT and Slt and score of corneal fluorescein staining began to recover in most of the affected eyes after surgery 14d. At 30d after surgery, 22%of patients tear film failed to recover to the preoperative level; dry eye occured in 18% preoperative eyes with normal tear film.CONCLUSlON:Trabeculectomy of glaucoma may affect the stability of the tear film and some patients showeing obvious dry eye and should be intervened and treatmented timely.

To investigate the role of ERC,6 gene in the growth rate and antifungal susceptibility,Aspergillus fumigatus strain with extra copies of ERG6 gene was constructed.Open reading frame (ORF) of putative ERG6 gene was searched in A.fumigatus genome.A PCR fragment, ERG6 ORF sandwiched by its flanking sequences (about 1 kb respectively),was amplified and was then subcloned into vector pRG-AMA1- NotI to produce a recombinant plasmid pERG6,which was further transformed into uracil auxotroph A.fumigatus strain AF293.1 to produce the transformant AF-pERG6.In the same time,empty plasmid pRG-AMA1-NotI was also transformed into A.fumigatus strain AF293.1 to produce the transformant AF-empty as a control.Radial growth of the transformants was tested on minimal medium (MM) and YAG medi- um.Antifungal susceptibilities of these resahing transformants,AF-pERG6 and AF-empty,to the common antifungal agents were performed by using both disk diffusion and broth microdillution methods.A.fumigatus genome contains a ERG6 gene,of which the ORF size is 1 256 bp.Comparing to Candida albicans and Sacchromyces cerivisiae sterol methyltransferase,A.fumigatus Erg6p had 57% and 50% identity, and had 70% and 63% similarity in amino acid sequences,respectively.Radial growth of transformant AF-pERG6 was slower than that of transformant AF-empty.The antifungal susceptibilties of transformant AF-pERG6 to the antifungal drugs itraconazole,voriconazole,terbin- aline,amphotericin B,caspofungin and grisefolvin were same to that of transformant AF-empty.In A.fumigatus,extra copies of ERG6 gene have no effect on antifungal susceptibilities to itraconazole,voriconazole,terbinafine,amphotericin B,caspofungin and grisefolvin.Radial growth of A.fumigatus harboring extra copies of ERG6 gene becomes slower compared to the control.
3.Study Progress of Cluster A in Homeobox Gene Family and Its Relationship with Leukemia
Journal of Applied Clinical Pediatrics 1993;0(03):-
Homeobox(HOX) gene is a kind of regulatory gene,which can regulate the embryonic development and cell differentiation,and participate in the regulation and control of hematopoietic stem/progenitor cell proliferation,differentiation and maturation,etc.Cluster A in HOX gene family is the master gene for proliferation and differentiation of hematopoietic stem/progenitor cells,which has an influence on the number of hematopoietic stem cells and the differentiation of hematopoietic stem cell into erythroid,myeloid,megakaryocytic and lymphatic system,and has a relationship with the generation of leukemia.In this article,study progress of Cluster A in HOX gene family and its relationship with leukemia were briefly stated.

BACKGROUND: Femoral prosthesis malrotation will lead to various complications, such as femoro-tibial and patellofemoral instability, and maladjustment of patellar movement trajectory, further affecting the recovery of the knee function.OBJECTIVE: To evaluate the influence of the rotation angle of the femoral prosthesis on the knee joint function after total knee arthroplasty (TKA).METHODS: Totally 146 patients (186 knees) undergoing TKA in the Department of Joint Surgery, Zhenjiang First People's Hospital from January 2010 to January 2014 were selected. Afterwards, the femoral condyle torsion angle was measured on CT to evaluate the rotational position of the femoral prosthesis. According to the condyle torsion angle, all the patients were divided into three groups: normal group (n=74, extorsion angle 3°-intorsion angle 3°), intorsion group (n=15, intorsion angle > 3°) and group (n=58, extorsion angle > 3°). All the patients were followed up for 3 years.RESULTS AND CONCLUSION: (1) The order of the activity function score was as follows: the normal group > extorsion group > intorsion group (P < 0.05). The standard activity, free activity and senior activity scores were highest in the normal group, followed by the extorsion group, and lowest in the intorsion group (P < 0.05). However, the standing and walking scores, as well as the satisfaction and expected scores did not differ significantly among groups. (2) That is to say, the rotational position of the femoral prosthesis influences the long-term knee joint function after TKA, so we should pay attention to the femoral prosthesis malrotation.

Objective To observe attenuation and synergy of postoperative chemotherapy combined with Tianzhicao capsule in patients who suffered from breast cancer. Methods 66 cases after radical mastectomy were randomly divided into treatment group 31 cases and 35 cases of control group. The patients of control group were treated with chemotherapies of CAF and TA. Treatment group patients were given Tianzhical capsule orally at the same time. Nausea and vomitting,the arrest of bone marrow before and after treatment were observed. The grade of life quality about every patient was evaluated. Results Myelosuppression and the occurrence of nausea and vomitting in treatment group was obviously lower than control group (P < 0.05). The proportion of improvement and stabilization for the quality of life in treatment group was markedly higher than control group (P < 0.05). Conclusion Traditional Chinese drug Tianzhicao capsule had attenuation and synergy to postoperative chemotherapy in breast cancer.

Objective To study the effect of leukoreduction transfusion on improving medical quality. Methods The cases in our hospital which had RBC transfusion records in the past 3 years were collected and divided into two groups: leukoreduction group(LR) and non-leukoreduction group(NLR). Through statistical analysis, the items related to leukoreduction were found out and the differences in these items between the two groups were compared. Results Operation complication, non-operation complication, infectious rate, transfusion reactions and mortality rate in LR group were significantly lower than those in NLR group. The transfusion of single components-RBC had less clinical side-effect than the transfusion of complex components including RBC. Conclusions Leukoreduction transfusion can effectively improve clinical therapy and promote the medical quality.
