BACKGROUND: Now, the current study has not yet confirmed two treatment methods of the proximal femoral nail antirotation and total hip arthroplasty for treating intertrochanteric fractures in the elderly, which method has more advantages, and there is no clear conclusion at present. OBJECTIVE: To systematical y compare the repair effect of proximal femoral nail antirotation and total hip arthroplasty for treatment of intertrochanteric fractures in the elderly. METHODS: We searched the related literatures from 2011 to 2015 on Wanfang database, PubMed, MEDLINE and Embase database by computer. We retrieved the journals in China by hand and col ected randomized control ed trials on proximal femoral nail antirotation and total hip arthroplasty in the treatment of intertrochanteric fractures in the elderly. Intraoperative blood loss, operation time, hospitalization time, ambulation time after operation, and Harris score were selected as evaluation indexes. Data were analyzed using RevMan 5.2 software. RESULTS AND CONCLUSION: Final y, 7 Chinese literatures were included, with 811 patients. The results of meta analysis showed that the hospitalization time and ambulation time after operation were significantly shorter in the total hip arthroplasty group than in the proximal femoral nail antirotation group (P < 0.000 01), which reduced the pain of patients. Operation time and intraoperative blood loss were poorer in the total hip arthroplasty group than in the proximal femoral nail antirotation group (P < 0.000 01). No significant difference in Harris hip score was detected between the two groups (P > 0.05). These results confirmed that the internal fixation of proximal femoral nail antirotation in minimal y invasive therapy when reducing operation time and blood loss has a certain advantage. The total hip arthroplasty can make the recovery of hip function earlier, al ow early weight-bearing walking, reduce the patients’ bedridden time and reduce the complications in bed. Thus, the clinicians in the practical work should choose the appropriate therapy with considering the patient’s condition, damage degree, fracture type, and financial capability.

Based on the associated theory of spleen-kidney deficiency about the traditional Chinese medicine and experimental research to discuss myasthenia gravis treated by integrative medicine.According to the theory of traditional Chinese medicine,the mechanism of myasthenia gravis is Qi deficiency of the spleen-stomach.Experimental studies showed supplementing spleen and kidney can improve ATP,muscle glycogen,fat content,other molecular biology material foundations,skeletal muscle cells under hypoxia and mitochondrial structure of animal models and patients,and therefore treat the deficiency of both spleen and kidney.

Background The special pathological change of diabetic retinopathy(DR)is microvascular disorder.Angiopoietin-like protein 2(Ang-2)is a new protein associated with genesis of blood vessels.Quercetin has multiple pharmacological action,including improving the microcircularion and the permeability of blood capillary.However,the action mechanism of Ang-2 on DR was unclear.Objective The present study was to investigate the effects of quercetin on Ang-2 and its receptor Tie2 expression in retina with diabetes mellitus.Methods Sixty clean male Wistar rats were randomized into 7 groups and 10 rats for each group,and 10 rats served as blank control group.Streptozotocin of 35 mg/kg was intraperitoneally injected in 60 rats to establish the diabetic models.Quercetins encapsulated by liposome with the doses of 50,150 and 250 mg/(kg · d)(3-5 ml)were used to gavage in different groups of models for 12 weeks,and normal saline solution and calcium dobesilate were used at the same fashion as the negative control group and positive control group,respectively.Twelve weeks later,the animals were sacrificed and retinas were isolated.Expressions of Ang-2 protein and Tie2 mRNA in retinas were detected by ELISA and RT-PCR,respectively.The usage and rearing of the animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Sciences and Technology Commission.Results ELISA showed that the A450 of Ang-2 in 150 and 250 mg/(kg · d)quercetin groups was 0.796±0.057 and 0.842±0.043 respectively and was lower than that negative group(1.012±0.046),showing statistically significant differences(q =2.95,2.698,P＜0.05).RT-PCR assay showed that expression of Tie2 mRNA(Tie2 mRNA/GAPDH mRNA)in retinas was 0.712±0.092 and 0.821±0.087,presenting statistically significant differences in comparison with negative group(1.182±0.098)(q =3.497,2.852,P＜0.05).The expression levels of Ang-2 and Tie2 mRNA in retina were lowest in 150 mg/(kg · d)quercetin group.Conclusions Quercetin can improve the retinal microcirculation by downregulating the expressions of Ang-2 and its receptor in early period of diabetic rats.
