Objective To summarize the nursing experience of combination therapy of highly agglutinative staphylococcin (HASL) with cisplatin for patients with malignant pleural effusions. Methods After fully draining of pleural fluid in 62 cases with malignant pleural effusion through pleural puncture through central venous catheters and simply suction bottles, we injected HASL and cisplatin into the patients' pleural cavities. During the therapeutic process, firstly, we drained the pleural fluid fully before injection, secondly, we directed the patients to cooperate well and alter the positions properly, and thirdly, we closely observed the patients' condition and adverse reactions. Results 54 of 62 cases were effective after the therapies. The effective rate was 87.1%.Conclusions In order to achieve a satisfled curative effect and reduce the adverse reactions, we need the cooperation of the patients, fully draining of the pleural fluid before injection and proper alternation of the patients' positions during the treatment process.

Micromachining of capillary electrophoresis chips is described.The current in channels was determined versus the voltage applied on the chip.Using laser-induced fluorescence detection,the process of injection and separation on chips was recorded with charge-coupled device(CCD).With defferent voltge of reservoirs on glass chips,profiles of the sample plug were studied. The elctropherogram of hydrolysis product of fluorescein isothiocyanate (FTTC-OH) and arginine labeled by fluorescein isothiocyante(FTTC-Arg) was obtained.

Objective To construct the prokaryotic expression vector of mouse CD25 extracellular domain and to express it in E coli.Methods Total RNA was isolated from splenocytes of Balb/c mice.The CD25 extracellular domain gene was amplified by RT-PCR and cloned into the PET-32a vector.A positive recombinant,PET-32a-CD25e,was identified by enzyme cleaving and sequencing before its expression in E.coli,and transferred into E.coli BL21(DE3) plysS for its expression.After purification with Ni+ resin and renaturation in vitro,a relative molecular mass(Mr) of the interesting protein was detected by SDS-PAGE and Wes-tern blotting.Effect of the purified interesting protein on the proliferation of splenocytes from T cell vaccine-immunized syngeneic mice was detected by MTT assay.Results The cloned CD25 extracellular domain gene was identified to be functional by sequencing and expression.The purified interesting protein could significantly induce the proliferation and IL-4 secretion of splenocytes from T cell vaccine-immunized mice in vitro.Conclusion Mouse CD25 extracellular domain gene can be successfully expressed in prokaryotic cells with biological activity,which lays a foundation for further relative studies.

BACKGROUND:Chondromodulin-Ⅰ is expressed mainly in the cartilage, but it is little expressed in mesenchymal stem cells. Combined with the previous study of our group, we concluded that chondromodulin-Ⅰmaybe play an important role in inducing mesenchymal stem cells into chondrocytes accurately.
OBJECTIVE:To construct an expression plasmid stably carrying chondromodulin-Ⅰ to up-regulate the expression of chondromodulin-Ⅰ in bone marrow mesenchymal stem cells.
METHODS:Specific primers were designed in rat cartilage for chondromodulin-Ⅰ gene, then the pcDNA3.1 (+) plasmid expression vector was digested by enzyme and directional connected gene to construct pcDNA3.1(+)/ChM-Ⅰ expression vector. Bone marrow mesenchymal stem cells were obtained from rats using the method of density gradient centrifugation combined with adherent culture. Recombinant plasmid pcDNA3.1(+)/ChM-Ⅰ was transfected into rat bone marrow mesenchymal stem cells with liposome method, and G418 selection was used for stable screen of transfected cells. Reverse transcription-PCR and western blot were used to detect chondromodulin-Ⅰ expression in celllines.
RESULTS AND CONCLUSION:The positive clones were digested by enzyme and were identified and sequenced. The results showed that the reality length and sequence of chondromodulin-Ⅰ gene were consistent with the theoretical values, and reading frame was correct. Reverse transcription-PCR and western blot results showed that the expressions of chondromodulin-ⅠmRNA and protein were markedly up-regulated in bone marrow mesenchymal stem cells. Recombinant plasmid pcDNA3.1(+)/ChM-I was successful y constructed, and transfected into rat bone marrow mesenchymal stem cells. After G418 selection, expression of chondromodulin-Ⅰ was up-regulated stably in rat bone marrow mesenchymal stem cells.

OBJECTIVETo systematically review the effectiveness of bone substitute augmentation combined with internal fixation versus internal fixation alone in treating proximal femoral fractures in the elderly.

METHODSSubject term and keywords were searched from Pubmed, Cochrane databases and CNKI from database foundation to August 2015. Randomized controlled studies and qusi-randomized controlled studies on bone substitutes augmentation combined with internal fixation versus internal fixation alone for the treatment of proximal femoral fractures in the elderly were chosen. Postoperative re-displacement, re-operation rate, complications (infection and bone ununion), functional outcome, quality of life scores and muscle strength were seen as outcome indicators. Enumeration data were statistical analyzed by risk difference and 95% confidence interval. Measurement data were analyzed by standardized mean difference and 95% confidence interval. If the same measurement data were evaluated by different standards in different studies, standardized mean differences and 95% confidence interval were used. The methods of statistical analysis were used by Cochrane databases.

RESULTSEleven RCTs (677 patients) were included. Meta-analysis results indicated that bone substitutes augmentation combined with internal fixation occurred fewer re-displacement [SMD = -0.75, 95% CI (-1.03, -0.47)] and obtained better function [SMD = 0.40, 95% CI (0.20, 0.59)]. While there were no significant differences in reoperation rate [RD = 0.02, 95% CI (-0.05, -0.09)], pain at 1 week after operation [MD = -1.79, 95% CI (-13.55, -9.96)], pain ranged from 6 to 8 weeks [MD = -7.24, 95% CI (-20.07, -5.59)], postoperative pain at 12 weeks [MD = -0.32, 95% CI (-4.9, -3.55)], muscle strength [MD = 1.25, 95% CI (-6.98, -9.48)], bone ununion [RD = 0.02, 95% CI (-0.01, -0.05)] and postoperative complications [MD = 0.01, 95% CI (-0.03, -0.04)].

CONCLUSIONCompared with single internal fixation, bone substitutes augmentation combined with internal fixation for the treatment of proximal femoral fractures in the elderly less occur re-displacement and could obtain better functional recovery.

OBJECTIVETo discuss the therapeutic effect of thenar perforator flaps for the narrow cicatricial contracture at thumb and the first web.

METHODSFrom Aug. 2010 to Jan. 2012, 9 cases with narrow cicatricial contracture at thumb and the first web, were treated. The defect size after releasing the contracture ranged from 8 mm x 20 mm to 15 cm x 30 mm. The bilateral thenar perforator flaps beside the wound were designed which size was 10 mm x 25 mm to 15 mm x 35 mm. The wounds at donor sites were closed directly.

RESULTSAll the 9 flaps survived completely with primary healing. The patients were followed up for 6-18 months. The flaps had soft texture and good appearance. The shape of flaps and function of the fingers were satisfied after 6-18 months of follow-up. There was no scar contracture at incisions in thenar. The thumb motion was really normal. The abduction of first web was 70 degrees - 90 degrees degrees.

CONCLUSIONSThe thenar perforator flaps is one of the ideal methods for the treatment of narrow cicatricial contracture at thumb and the first web. The main artery is not sacrified.

?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.
