OBJECTIVETo investigate the application of combining mastopexy and triple-plane breast augmentation in correction of breast ptosis and atrophy.
METHODSPeri-areolar incision was performed to finish the fascia and dermal suspension to correct the breast ptosis. The implant was inserted under the pectoralis major muscle through lateral lower border of the gland and a "X" shape full thickness incision was made on the pectoralis major muscle according to the new position of nipple-areolar complex.
RESULTS14 patients received combined mastopexy and triple-plane breast augmentation to correct breast atrophy and mastopexy simultaneously. All the patients were regularly followed for 6-12 months. No patients suffered severe complication and the results were satisfied.
CONCLUSIONS"Triple-plane" breast augmentation could be safely performed with peri-areolar mastopexy with minor injury. The technique could help to ensure the balance between the gland, nipple-areolar complex and the implant.

OBJECTIVETo study the relationship between Chinese medical syndrome types and metabolomics of non-small cell lung cancer (NSCLC) patients.
METHODSTotally 120 NSCLC patients were assigned to asthenia syndrome group and sthenia syndrome group, 60 in each group. Meanwhile, 60 cases of benign pulmonary nodules in physical examinations were recruited as the control group. Tumor tissues or benign pulmonary nodules tissues were obtained by thoracoscope. Changes of their metabolites were observed using gas chromatography-mass spectrometry (GC-MS). Their differences were studied using principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA). ROC curve analysis was performed in different metabolic compounds of sthenia and asthenia syndromes groups. The area under the curve (AUC) was calculated to evaluate the sensitivity of diagnosing syndrome types.
RESULTSCompared with the control group, difference existed in 16 compounds. Of them , contents of citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, linoleic acid, oleic acid, lactic acid, inositol were more in the two tumors group than in the control group. Difference existed in 10 compounds between the sthenia syndrome group and the asthenia syndrome group. Of them, citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, lactic acid, and inositol were more in the asthenia syndrome group than in the sthenia syndrome group. Contents of valine, glucose, and glutamine were more in the sthenia syndrome group than in the asthenia syndrome group. ROC curve analyses of different compounds indicated that AUC of lactic acid and glucose was more than 0.8 (P < 0.01); AUC of inositol, choline phosphate, and glycerol phosphate choline was more than 0.7 (P < 0.01); AUC of valine, citric acid, glutamine, alanine, and pyruvic acid was more than 0.6 (P < 0.05).
CONCLUSIONSThere existed certain correlation between CM syndrome types and metabolomics of lung cancer. Lactic acid, glucose, inositol, choline phosphate, glycerol phosphate choline, valine, citric acid, glutamine, alanine, pyruvic acid were sensitive diagnostic compounds, and the first four kinds were most sensitive compounds.

OBJECTIVETo compare therapeutic effects between patella replacement and patella osteotomy in total knee arthroplasty.
METHODSFrom April 2004 to April 2011, 52 patients (54 knees) were enrolled in the clinical trail of total knee arthroplasty, who received patella replacement (24 knees, including 13 males and 11 females,ranging in age from 53 to 78 years old or patella osteotomy (30 knees,including 16 males and 12 females,ranging in age from 55 to 79 years old. The average follow-up period was 56 months,ranging from 20 to 80 months. The American HSS Score for knee, the Feller score for patella, range of motion (ROM) for knee, patient satisfaction and complications related to the patella were used to evaluate therapeutic effects.
RESULTSIn the patella replacement group,the preoperative and final follow-up HSS scores of patients were 38.4 +/- 8.2 and 91.2 +/- 8.6 respectively; Feller scores were 13.6 +/- 6.2 and 25.2 +/- 4.2; scores of anterior knee pain were 3.9 +/- 3.2 and 11.2 +/- 3.7; ROM were (78 +/- 26) degrees and(108 +/- 18) degrees. In the patella osteotomy group,the preoperative and final follow-up HSS scores of patients were 39.5 +/- 8.4 and 91.0 +/- 8.5 respectively;Feller scores were 13.4 +/- 6.5 and 25.6 +/- 4.0; scores of anterior knee pain were 3.7 +/- 3.1 and 11.3 +/- 3.6; ROM were (76 +/- 27) degrees and (110 +/- 19) degrees. In the patella replacement group,patient's satisfaction was 91%, and complication related to the patella was 16.7%; in the patella osteotomy group, patient's satisfaction was 89%, and complications related to the patella was 10.0%. There were no statistically significant differeneces in final follow-up HSS scores, Feller scores, scores of anterior knee pain and ROM between the two groups. However,there was no significant difference of patient's satisfaction between them. There was statistically significant differenece of patella-related complications between the two groups, and the complication rate in the patella replacement group was higher than that in the patella osteotomy group.
CONCLUSIONTotal knee arthroplasty with patella replacement or patella osteotomy dramatically relieves pain and improves the knee function. Patella-related complications are associated with its treatment methods, but post-operative anterior knee pain and patient's satisfaction are not related to treatment methods of the patella.

·AIM: To investigate the effect of the dipeptide Arg-Glnon retinal neovascularization of retinopathy of prematurity(ROP) in the oxygen-induced retinopathy (OIR) animalmodel.·METHODS.- Forty-eight 7-day-old C57BL/6J mice were exposed to 750mL/L oxygen for 5 days and then to normal situation to produce the murine model of oxygen-induced retinopathy (OIR). All mice received twice daily intra- peritoneal injections of PBS or the dipeptide Arg-Gln(1.0, 3.0, 5.0g/kg per day), starting on postnatal day 12 and continuing till postnatal day 17. Experimental groups (36 mice, 12 in each group) received Arg-Gln, while the control group (12 mice) received PBS. All mice were executed at postnatal day 17. The changes of retinal vessels of mice were observed by ADPase histochemical technique and HE staining was used to count preretinal neovascular nuclei. RNA was isolated from retinas of 28 mice (7 in each group) selected at random and VEGF mRNA level of each group was measured by real-time RT-PCR.·RESULTS; Neovascularization reduced in retinas of the dipeptide Arg-Gln treated group in a dose-dependent manner. Compared with control group, experimental group had diminished non-perfusion area and neovascular tufts in retinal flatmount. The number of the endo-theliocyte nuclei of new vessels extending from retina to vitreous was significantly less in the eyes of the experimental group than in control group. Arg-Gln at 5g/kg per day reduced preretinal neovascularization by about 75% (P< 0.01). There was a significant reduction in VEGF mRNA at the 17th day in Arg-Gln treated group compared with control group(P<0.01).·CONCLUSION; Arg-Gln dramatically inhibits retinal angiogenesis in OIR and this effect is associated with a reduction in retinal VEGF mRNA level. It appears to be a safe way to prevent and treat some neovascular retinal diseases including retinopathy of prematurity.
