Objective Transforming growth factor-β( TGF-β) can regulate the expressions of matrix metalloproteinase (MMP) and matrix metalloproteinase (TIMP) inhibitors, thus affecting the reconstruction of extracellular matrix (ECM) after lung in-jury.So far, little is known about the regulation of TGF-β1 and MMPs/TIMPs ratio in endotoxin-induced lung injury as well as about the exact mechanisms of ECM reconstruction disorders .This study was to investigate the effects of TGF-β1 antibodies on the expressions of MMP and TIMP inhibitors and lung injury fibrosis in rats with endotoxin-induced acute lung injury . Methods Fifty-six male SD rats were randomly divided into three groups, normal (n=16), LPS (n=20), and LPS+TGF-β1(L+T, n=20).The rats of the LPS and L+T groups received intraperitoneal and intra-tracheal injection of endotoxin to induce lung injury fibrosis , the latter intrave-nously injected with TGF-β1 antibodies previously .The normal rats received intra-tracheal and intra-abdominal injection of the same a-mount of saline.At 1, 5, 9 and 14 days after modeling, all the rats were killed and blood and lung tissue samples obtained to detect the wet/dry lung tissue ( W/D ) ratio, diffuse alveolar damage ( DAD) score, hydroxyproline activity ( Hpy) , and the expressions of TGF-β1 , MMP-2 and TIMP-1. Results The DAD score, Hpy ac-tivity, and expressions of TGF-β1 , MMP-2 and TIMP-1 were signifi-cantly higher in the LPS group than in the normal control ( P <
0.05), and so were the DAD score, Hpy activity, MMP-2, and TIMP-1 in the L+T group than in the controls (P<0.05).Com-pared with the LPS group, Hpy, TGF-β1 and TIMP-1 were markedly decreased in the L +T group (P<0.05).The expression of MMP-2 was gradually increased at 1, 5 and 9 days after modeling , reaching the peak at 9 days and then beginning to decline .The Hpy activity, TGF-β1 and TIMP-1 expressions kept rising after modeling . Conclusion The MMP/TIMP imbalance and ECM reconstruc-tion disorders mediated by the TGF-β1 signaling pathway may be an important cause of fibrosis in endotoxin-induced lung injury . TGF-β1 antibodies can exert a protective effect by alleviating lung injury fibrosis .

Objective To study the clinical effect of personalized intervention on elderly patients with colostomy after Miles operation for rectal carcinoma. Methods 114 cases elderly patients with colonic stoma after Miles operation for rectal cancer from June 2014 to January 2016 were divided into control group and observation group by random number method, 57 cases in each. The control group were treated with routine intervention, while patients in observation group was treated with personalized intervention. the self-care ability score before intervention, the incidence of complications, intervention satisfaction and life quality score were compared between the two groups at the same time. Results The total complication rate in the observation group was significantly lower than that in control group ( 5.25% vs 22.80%) (χ2 = 8.36, P = 0.000); the intervention satisfaction of the observation group was significantly higher than that in control group (91.23% vs 75.44%) (χ2 = 6.60, P = 0.010). After intervention, the self-care ability score and life quality score of observation group were significantly higher than that in control group (P < 0.01). Conclusion The personalized intervention can reduce the complications, significantly improve the patients' life quality score and self-care ability, and effectively alleviate the negative situation, improve the patients intervention satisfaction, with a higher development value, it is worth of clinical promoting.

Objective To explore the clinical results of total knee arthroplasty (TKA) in the treatment of knees with bony ankylosis in extension.Methods From June 2000 to June 2007,10 patients had knees with bony ankylosis in extension were treated with TKA,including 4 males and 6 females,with an average age of 49 years (range,29 to 63 years).The primary diseases were as follows:ankylosing spondylitis in 3 cases,rheumatoid arthritis in 2 cases,hemophilic arthritis in 1 care,traumatic arthritis in 3 cases and pyogenic arthritis in 1 case.The range of motion (ROM) was 0° in all knees,and the average HSS (the Hospital for Special Surgery) score before operation was 32.5±10.26.Two patients underwent bilateral TKA,and 8 underwent unilateral TKA.Results All patients were followed up for 3 to 10 years (average,5.3 years).The average HSS score was improved to 87.75±6.45 at the last follow-up,and there was significant difference compared with that before operation (t=18.668,P=0.000).The average ROM was improved to 97.08°±11.57°at the last follow-up,and there was remarkable difference compared with that before operation (t=29.063,P=0.000).The postoperative complications included cutaneous necrosis in 2 cases,deep venous thrombosis of lower limb in 1 case,periprosthetic fracture in 1 case,and deep prosthetic infection in 1 case who underwent revised TKA later.The postopertative X-ray showed no looseness of the prostheses.Conclusion TKA through medial parapatellar approach,with dissection of the rectus femoris,secondary osteotomy and soft tissue balance intraoperatively is effective in the treatment of knees with bony ankylosis in extension,which can correct the ankylosed knee deformitis successfully.Combining with the correct rehabilitation exercise,it is possible to improve significantly the function of knee and life quality in these patients.

OBJECTIVETo analyze the origin of the feeding artery of the retroperitoneal invasion caused by massive hepatocellular carcinoma (HCC) and the characteristics of DSA. To explore the approaches to completely embolize the tumor blood supply and to assess the technical success rates, the safety and effectiveness with a purpose of improving the patients survival rates and living quality.

METHODSAfter complete ultraselective arterial embolization via hepatic artery for the 75 patients with retroperitoneal invasion led by massive HCC, those showing lipiodol deposition inconsistance compared with CT or MRI underwent the ultraselective catheterization to find potential tumor feeding arteries and then the subsequent chemoembolization. 3-6 months after operation CT or MRI was used to evaluate the efficacy. RETURNS: Retroperitoneal lesions were supplied by the posterior branch of right inferior phrenic artery (64%, 48/75), the right adrenal artery (33.3%, 25/75) and the right-side first lumbar artery (2.7%, 2/75), respectively. The success rates of ultraselective catheterization to tumor feed arteries was 100% (75/75). 3-6 months after embolization, the cases of complete and most-part iodine oil filling in the lesions were 72 (96%) and 3 (4%) respectively. The sizes of the lesions showed significant reduce (55, 73.3%), reduce (15, 20%) and no change (5,6.7%). Survival rates of 6, 12, 24 and 36 months after TACE were 90.7% (68/75), 81.3% (61/75), 49.3% (37/75) and 40% (30/75) respectively.

CONCLUSIONThe supply arteries of retroperitoneal invasion led by massive HCC come from the posterior branch of right phrenic artery, the right adrenal artery and the right first lumbar artery. Ultraselective TACE has high technical success rates, hight safety, and excellent effectiveness. The complete embolization of tumor feed artery can significantly increase the survival rates and living quality of these patients.

BACKGROUND: Periprosthetic joint infection (PJI) is a serious and catastrophic complication after hip or knee arthroplasty. With aging population increasing, more patients will undergo hip or knee arthroplasty. Studies have shown that the risk for PJI following arthroplasty is different in different populations. OBJECTIVE: To evaluate the risk factors for PJI after hip or knee arthroplasty in Mainland of China through a meta-analysis, thereby providing reference for the prevention and control of postoperative PJI. METHODS: A computer-based search of WanFang, CNKI, VIP, CBM, PubMed, Cochrane, Embase and Medline databases was performed and the literatures concerning the risk factors for PJI after hip or knee arthroplasty in Mainland of China published before September 2016 were collected by manual retrieval and retrospective approach. All the literatures were screened based on the inclusion and exclusion criteria, followed by data extraction and analyzed on RESULTS AND CONLUSION: (1) Finally 14 literatures were included, including 417 patients with PJI. (2) The results of the meta-analysis showed that the risk factors for PJI after hip or knee arthroplasty including the complication of diabetic mellitus, long-term use of steroids, long operation time (> 90 minutes), age (> 65 years), and history of hip or knee Stata 12.0 software. surgery. (3) To conclude, PJI after hip or knee arthroplasty is related to multiple factors, so physicians should pay attention to these factors to reduce the incidence of PJI.

Objective:To validate the role of color Doppler ultrasound in an animal model to detect early heterotopic ossification (HO) after brain-traumatic/burn/tenotomy.Methods:Forty-four rats were randomly divided into two groups. Rats in experimental group ( n=22) were operated to build brain-traumatic/burn/tenotomy model and others in control group ( n=22) underwent only skin incision injury. Color Doppler ultrasound, X-ray film examination at 2, 3, 4, 6, 8 and 10 weeks post-injury were performed to follow up the progression of HO in both groups respectively. Histology was used to confirm bone formation. Results:In the experimental group, disorder structure with a hypoechoiccore in treated Achilles tendon was visualized using color Doppler ultrasound in the 2nd week. Additional tiny hyperechoic foci were observed in the 3rd week, which increased in the fourth week and fused into a mineralized island in the sixth week. No obvious abnormality was found in control group at the aforementioned time point. X-ray could detect heterotopic bone tissue in the sixth week in the experimental group but not in the control group. X-ray and HE stainning had confirmed bone formation in the tenth week in the experimental group.Conclusions:Color Doppler ultrasound can detect early HO and continuously follow up the progression of HO.
