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.

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.

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.

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.

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 observe the primary prevention role of Wuling Capsule (WC) on poststroke depression (PSD) patients.

METHODSAcute stroke patients were recruited and randomized into 2 groups by stratification, 55 in each group. All patients received same routine treatment of cardiovascular diseases. Patients in the experimental group additionally took WC (0.33 g each pill), 3 pills per day, three times per day; while those in the control group additionally took placebos, 3 pills per day, three times per day. Two weeks consisted of one therapeutic course. The diagnosis of PSD was performed once every other week. Those in accordance with PSD diagnosis discontinued any drug therapy. Those not in accordance with PSD diagnosis continued the drug therapy for 1-12 therapeutic course(s) (in total of 6 months). If they were still not in accordance with PSD diagnosis, then they discontinued the drug therapy. The morbidity of PSD, the average time of depression occurrence, Hamilton depression rating scale (HAMD) score, and adverse reactions were observed.

RESULTSThe 1-, 3-, and 6-month morbidity of PSD was 8%, 16%, and 34% in the experimental group, while they were 19.6%, 29.4%, and 54.9% in the control group. The occurrence rate was lower in the experimental group than in the control group. Besides, there was statistical difference in the 6-month occurrence rate between the two groups (chi2 = 4.465, P < 0.05). The average time of PSD occurrence was longer in the experimental group than in the control group (14.96 +/- 8.31 weeks vs. 9.36 +/- 6.06 weeks; t=6.762, P < 0.05). The HAMD score at the PSD occurrence was 11.96 +/- 2.14 in the experimental group, lower than that of the control group (14.57 +/- 4.24), showing statistical difference (t=5.641, P < 0.05).

CONCLUSIONWC was superior to the placebos in lowering the incidence of PSD, delaying the occurrence time of PSD, attenuating the depression degree of PSD, and had certain preventive effect on the incidence of PSD.
