Objective To study the curative effect of arthroscopic debridement in the treatment of knee osteoarthritis with moderate-to-severe degenerative cartilage. Methods Arthroscopic knee debridement combined with postoperative rehabilitation exercise was carried out in 17 cases (21 knee joints) of knee osteoarthritis with moderate-to-severe degenerative cartilage. Results The operation time was 55~100 min (mean, 75 min). No surgical complications occurred. The postoperative hospital stay was 15~ 20 days (mean, 13 days). The passive range of motion of the knee joint during the surgery was 0?~120? and the range of motion after the surgery, 0?~110?. Follow-up was conducted for 5~36 months (mean, 21 months). The curative effect was classified as “good” in 6 cases (8 joints), “fair” in 9 cases (11 joints) and “poor” in 2 cases (2 joints). The range of motion of the knee was 0?~ 120?. Conclusions Arthroscopic debridement is an effective option for the treatment of knee osteoarthritis with moderate-to-severe degenerative cartilage.

Objective To understand the clinical feature of the elderly patients with diabetes during coronary angiography,and analyze the risk factors of contrast-induced nephropathy (CIN).Methods The clinical data of 269 elderly patients who had undergone coronary angiography and percutaneous coronary intervention(PCI) from January 2007 to December 2009 in our hospital were analyzed retrospectively.The patients were divided into two groups:CIN group and non-CIN group.The possible risk factors for CIN,such as glycemic control,diabetic complication,renal function,volume of contrast medium,inflammatory state,therapy of perioperative period,past medical history were analyzed and compared between the two groups. Results In 269 elderly patients with diabetes,the incidence of CIN was 9.3 ％ (25/269).According to estimated glomerular filtration rate (e-GFR),the patients were divided into four subgroup:≥90 ml/min,89-60 ml/min,59-30 ml/min,＜29 ml/min.The incidences of CIN for the subgroups were 2.2％(1/45),4.4％(6/135),17.3％(14/81) and 50 ％ (4/8),respectively.Multivariate logistic gradual regressive analysis showed that loop diuretic use (OR＞ 6.07),preoperative e-GFR(＜60 ml/min) (OR＞3.27),volume of contrast medium (≥200ml) (OR＞3.26),chronic kidney disease(CKD) (OR＞2.80) (P=0.001,0.024,0.015,0.048) were indepen-dent risk factors for CIN (P＜0.05). Conclusions Loop diuretic use,preoperative GFR (＜60 ml/min),volume of contrast medium (≥200 ml) and CKD are independent risk factors of CIN.

Based on the counting results from nutrition agar in our study, and compared with another two kinds of coliform bacteria detective plates for dinner and drinking sets which were provided by two manufactures and inspected by China National Health Bureau , we accomplished the detectability test of the Huankai coliform bacteria plates. In our study, 3kinds of cell density were adopted: 10cells/mL, 50cells/mL and 100cells/mL . The results shew that the detectability of Huankai plates basically conformed with that of nutrition agar , and was no evident difference from that of another two kinds of plates. The conclusions were that Huankai plates can completely be used in the inspection and test for conform bacteria.

OBJECTIVETo discuss the results and significance of the detection of the CFTR gene mutation in azoospermia patients with congenital unilateral absence of the vas deferens (CUAVD).

METHODSWe collected peripheral blood samples from 6 azoospermia patients with CUAVD for detection of the CFTR gene mutations and single nucleotide polymorphisms. We analyzed the genome sequences of the CFTR gene in comparison with the website of the UCSC Genome Browser on Human Dec. 2013 Assembly.

RESULTSMissense mutation of c. 592G > C in exon 6 was found in 1 of the 6 azoospermia patients with CUAVD and splicing mutation of c. 1210-12T[5] was observed in the noncoding region before exon 10 in 2 of the patients, both with the V470 haplotype in exon 11.

CONCLUSIONMutations of the CFTR gene can be detected in azoospermia patients with CUAVD and the detection of the CFTR gene mutation is necessary for these patients.

Objective To analyse clinical application of reversed anterolateral thigh adipefascial flap in repair of defects around the knee. Methods Reversed anterolateral thigh adipofascial flap was employed to repair defects of knee and upper shank in five patients from July 2006 to April 2007. The perforator arteries were detected and labelled with a hand held Doppler flowmeter before operation. The size of flaps containing perforator artery ranged from 6 cmx 8 cm to 12 cm×13 cm. After the descending branch was severed at the bifurcation of the lateral circumflex femoral artery, the flaps were elevated distal-ly to cover the defects of the knee and upper part of the shank. A split thickness graft was harvested to cover the flap. Results All the reversed anterolateral thigh adipofascial flaps survived well, with no complications occurred in donor site. Partial graft necrosis occurred in one patient and healed after conser-vative wound dressing change. Conclusion The reversed anterolateral thigh adipofascial flap is a good choice for repair of defects around the knee, for it can provide long thin vascular pedicle and maintain contour of the donor cite.
