Objective To explore the clinical curative effect of locking plate in elderly patients with proximal humeral fractures. Methods Seventy elderly patients with proximal humeral fractures were selected, and all patients were treated with surgical treatment. Among them, application of locking plate was in 35 cases (locking plate group), and application of ordinary steel plate was in 35 cases (ordinary steel plate group). The operation time, intraoperative blood loss, fracture healing time and curative effect between 2 groups were compared. Results The operation time, intraoperative blood loss and fracture healing time in locking plate group were significantly lower than those in ordinary steel plate group: (61.3 ± 5.6) min vs. (78.3 ± 4.2) min, (190.5 ± 11.5) ml vs. (268.5 ± 21.2) ml and (12.6 ± 1.8) weeks vs. (16.5 ± 1.5) weeks, the excellent and good rate was significantly higher than that in ordinary steel plate group: 94.29% (33/35) vs. 74.98% (26/35), and there were statistical differences (P<0.05). Conclusions The curative effect of locking plate in elderly patients with proximal humeral fractures is accurate. Locking plate can be fixed firmly, and it is conducive to early recovery after surgery.

0.05).Both SBP and DBP were declined significantly in both two groups(P0.05).Heart rate decreased from (81?9)b/min to (68?7)b/min in bisorpolol group.But there wasn't this effect in contrast group.It was superior to that of contrast group significantly too(P

Background Proliferative vitreoretinopathy (PVR) is a a common cause of anatomic failure in retinal detachment surgery.Proteomics is the critical method to investigate the different proteins. Objective This study was to search for related vitreous proteins in rhegmatogenous retinal detachment patients with proliferative vitreoretinopathy (PVR)and screen for the related protein expression in the vitreous with PVR. Methods Vitreous samples were obtained from 8 moderate PVR (grade B)eyes and 8 severe PVR(grade C or D)eyes during pars plana vitrectomy (PPV)for the proteomics analysis by two-dimensional gel electrophoresis coupled with mass spectrometry.Normal vitreous from 8 healthy donor eyes served as control.First dimension isoelectric focusing (IEF) was performed with the Pharmacia IPGphor in solvent B using 18 cm non-linear pH 3-10 immobilized pH gradient (IPG)strips.IPG strips were rehydrated with sample,and then IEF was performed.The second dimension 12%sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) was performed after the IPG strips were equilibrated.After silver staining,the gels were analyzed by the 2-DE gel analysis software.The matched spots were excised and tryptica digested in-gel.The peptides were analyzed by MALDI-TOF-MS and the MS/MS spectral were searched against the human protein databases using MASCOT.This study process complied with the Declaration of Helsinki.Wfitten informed consent was obtained from each patient prior to this trial. Results In the current study,a total of 47,184 and 336 protein spots were detected from the normal donor eyes,moderate PVR eyes and severe PVR eyes,respectively,by 2-DE gels.Among 13 protein spots with significant differences in the 3 groups,7 types of proteins were successfully identified.The results indicated that Enolase 2 was a specific protein for normal donor vitreous.whereas transthyretin monomer and retinol-binding protein(RBP) chain B were distinct proteins found in severe PVR vitreous.and prostaglandin D synthase and RBP3 precursor were common proteins with up-regulated expression in vitreous samples with moderate PVR,but down-regulated levels in vitreous samples with severe PVR.The levels of albumin and transferrin in vitreous showed dynamic elevation with the enhancement of severity of PVR.Conclusion The changes in the vitreous proteome imply that some types of vitreous proteins degrade and some common serum proteins are expressed in the vitreous body with PVR,which indicated the disruption of the blood retinal barrier in the pathogenesis of PVR.

Objective To explore the effect of nutritional intervention on nutritional status,weight,physical strength and quality of life of patients with head and neck cancer treated by radiotherapy.Methods 77 patients with head and neck malignant tumors treated by radiotherapy were divided randomly into two groups,nutritional intervention group (NI) had 38 cases and control group (CG) had 39 cases.The status of nutrition,weight,physical strength and quality of life before radiotherapy,the end of radiotherapy and 3 months after radiotherapy in two groups were compared.Results The nutritional risks in two groups had no difference before radiotherapy.At the end of radiotherapy,the assessment score of the nutrition in NI was significantly lower than that in CG [(5.41±2.36) scores vs.(6.92±2.74) scores,t =4.935,P ＜ 0.05],and the average weight in NI was significantly higher than that in CG [(57.07±8.01) kg vs.(46.53±9.82) kg,t =2.670,P ＜ 0.05].At the end of radiotherapy and 3 months after radiotherapy,the physical strength in NI [(57.07± 8.01),(41.48±7.92) kg] were significantly higher than those in CG [(36.43±6.48),(37.94±8.03) kg] (t =2.670,P =0.021;t =2.361,P =0.037);the index of quality of life in NI [(51.37±6.56),(52.07±6.23) scores] were also significantly higher than those in CG [(46.93±6.98),(48.13±7.12) scores] (t =2.292,P =0.041;t =2.076,P =0.037).Conclusion Nutritional intervention can effectively maintain the nutritional status of head and neck cancer patients with radiotherapy,and improve continuously the physical strength and the quality of life.

OBJECTIVE:To evaluate the economical efficiency of alogliptin for type 2 diabetes and provide clinical evi-dence for related researches. METHODS:Retrieved from Cochrane Library,Pubmed,EMBase,CNKI,VIP,Wanfang,CBM database up from the start of the database to Mar.,2014,RCTs about alogliptin combined with traditional antidiabetic agents regimen vs. traditional antidiabetic agents regimen in the treatment of type 2 diabetes mellitus were included. Based on the sec-ondary analysis method of literatures,Effectiveness indexes and treatment course were extracted from the literatures,from the perspective of patients,and daily treatment cost was used to calculate the cost;cost-effectiveness analysis was adopted to evalu-ate the economical efficiency of alogliptin combined with traditional antidiabetic agents regimen vs. traditional antidiabetic agents regimen. RESULTS and CONCLUSIONS:6 literatures which met inclusion criteria were included. When alogliptin com-bined with metformin treatment lasted for 12 weeks,the decrease value of HbA1c as effect index showed poor cost-effective-ness;when treatment course increased to 26 weeks,the rate of qualified HbA1c as effect index showed poor cost-effectiveness. When the price of alogliptin decreased by 10% or the effects of trial group was the upper limit of 95%CI,the cost-effective-ness was superior to metformin regimen group. 12 weeks of alogliptin combined with pioglitazone treatment showed better cost-effectiveness than pioglitazone alone using the decrease value of HbA1c as effect;when treatment course increased to 26 weeks,the treatment showed poor cost-effectiveness;when treatment conrse increased to 26 weeks,using the rate of qualified HbA1c as effect indes,the results of sensitirity analysis showed that cost-effectiveness of trial group was better than that of pio-glitazone alone group as the apper limit of 95% CI. When alogliptin combined voglibose treatment lasted for 12 weeks,the de-crease value of HbA1c as effect index showed superior cost-effectiveness to voglibose regimen group. It is suggested to develop alogliptin pharmacoeconomics research based on RCTs and pharmacoeconomics research about improving diabetes patients’ long-term living quality.

Objective To compare the influences of different routes of nutrition on the outcome and respiratory muscle strength of elderly patients in respiratory intensive care unit (RICU). Methods Totally 147 elderly patients in RICU were equally randomized into combined nutrition group ( combinination of parenteral nutrition and enteral nutrition), total enteral nutrition (EN) group, and total parenteral nutrition (PN) group. The changes of energy metabolism, respiratory muscle strength, and short-term outcome were observed or determined.Results Plasma albumin (ALB), hemoglobin (Hb), creatinine (Cr) levels, and nitrogen balance significantly increased in all group 7 days later ( all P ＜ 0. 01 ), while blood urea nitrogen (BUN) significantly decreased ( P ＜0.01 ). The increase of ALB, Hb, Cr levels, and nitrogen balance were significantly more remarkable than that in EN group and PN group (P＜0.05 or P＜0.01). The decrease of BUN level in the combined nutrition group was significantly more remarkable than that in EN group ( P ＜ 0. 05 ). After nutritional support, the maximum inspiratory pressure in the combined nutrition group (P =0. 021 ) and EN group (P = 0. 011 ) became significantly higher, and occlusion pressure at 0.1 second inspiration level in the combined nutrition group became significantly lower ( P =0. 025). The incidences of infectious and non-infectious complications in PN group were significantly higher than those in EN group (P = 0. 002 and 0. 017, respectively) and combined nutrition group ( P = 0. 005 and 0. 004, respectively). Gastric retention was more common in EN group than that in PN group ( P = 0. 035). The weaning time,length of RICU stay, length of hospital stay and 20-day-mortality were significantly decreased in the combined nutrition group than those in the other two groups ( all P ＜ 0. 05 ). Conclusion The effectiveness of the combined application of PN and EN is superior to PN or EN alone in improving nutritional status and respiratory muscle strength as well as in improving the short-term outcome in elderly patients in RICU..

AIM To discuss the effects of losartan on AT 1R mRNA expression and renin angio tensin system (RAS) level in brain of spontaneously hypertensive rat (SHR). METHODS Sixteen 6 week old male SHR and 16 sex and age matched WKY were divided into losartan ( n =8) and control groups ( n =8) respectively. Losartan (30 mg?kg -1 ?d -1 ) or equal volume of 0.9% saline solution was administered for 18 weeks by gavage. AT 1R mRNA expression was examined by reverse transcription polymerase chain reaction (RT PCR). Renin activity (RA) and angiotensinⅡ(AngⅡ) levels were measured by radio immunoassay. Angiotensin converting enzyme activity (ACEA) was measured by ultraviolet spectrophotometar. RESULTS Enhanced brain AT 1R mRNA expression was found in SHR compared with WKY ( P 0.05, respectively). CONCLUSION The increase of AT 1R mRNA expression and RAS levels in brain may be involved in the pathogenesis of hypertension in SHR. Losartan protects brain by decreasing expression of brain AT 1R mRNA.

Objective To explore the effects of music intervention on growth and development of premature infants. Methods 112 premature infants were randomly divided into the observation group and the control group with 56 cases in each. The control group received conventional nursing measures, and the observation group was simultaneously given music intervention besides the conventional routine nursing measures. Weight increase, hospitalization time, milk-intake volume and feeding tolerance were compared between the two groups. Results The weight increase in the observation group was higher than that in the control group. Hospitalization time and rate of feeding intolerance for the observation group was lower compared with that of the control group. The premature infants in the observation group took in more milk than those in the control group. Conclusions Music intervention can elevate feeding tolerance, facilitate nutrition and increase weight of premature infant, so it is beneficial to the growth and development of premature infant.

Objective To observe the impacts of valsartan combined with amlodipine or hydrochlorothiazide regimen on blood pressure variability (BPV) in elderly hypertensive patients.Methods Eighty elderly patients with hypertension were randomized into valsartan and amlodipine (the amlodipine group, n=38) or valsartan and hydrochlorothiazide (the hydro-chlorothiazide group,n=37) group.The 24-hour dynamic blood pressure was monitored at baseline, 6-week and 12-week after treatment for the blood pressure and blood pressure variability. The control rate of blood pressure was calculated at 6-week after treatment, and side effects were observed during the treatment.Results Values of 24 h systolic blood pressure (SBP), daytime SBP, nighttime SBP, morning SBP and 24 h systolic blood pressure variability (SBPV) were significantly low-er at 6-week and 12-week than those of baseline in both two groups(P<0.05). There was an interaction between the group-ing factors and time on 24 h SBP, daytime SBP, nighttime SBP, 24 h SBPV and daytime SBPV (P<0.05). At the 6 and 12-week treatment, 24 h SBP, daytime SBP, nighttime SBP and daytime SBPV were significantly lower in amlodipine group than those in hydrochlorothiazide group (P<0.05). At 12-week treatment, 24 h SBPV was significantly lower in amlodipine group than tjat in hydrochlorothiazide group (P<0.01). There were no significant differences in control rate of blood pressure and side effects between two groups. Conclusion Valsartan in combination with amlodipine or hydrochlorothiazide can both ef-fectively control BPV in elderly hypertensive patients, and valsartan conbined with amlodipine has better effects on lowering blood pressure and BPV.
