ObjectiveTo report the clinic result of bone and skin defects of forefoot and defects of forefoot treated by allograft and complex flap of crural artery with nerve and periosteum. Methods Allograft and complex flap with periosteum of tibien were used to repair bone and skin defects of forefoot in 9 cases ,in which the defects of forefeet were reconstructed by sequential connection with the complex flaps of tibialis posterior artery with saphenous nerve and periosteum in 2 cases. Results Six cases were survived completely;distal part in surface layer of flaps were necrosis partly in 3 cases and healed by dressing. After operation ,the repaired bone and joint showed normal position and recovered arcus pedis transversalis and arcus pedis longitudinalis by X-ray films. The patients were followedup from 3 months to 3 years,all grafted allograft had showed bone union and hadnt showed complications such as absorption,infection and repulsion. The injuried foot was restored its weight-bearing and walking functions and obtained a satisfactory contour. After operation,sensory recovery of foot occurred about 2 months. ConclusionUsed allograft is easy to do and recover arcus plantaris. The reverse complex flaps of tibialis anterior artery with periosteum have advantages as follow :the advoidance of influencing blood supply of injuried foot ,advancing symphysis ,short treatment course,simply procedure ,walking functions recovered ,good appearance and sensation.
2.Current understanding of ABCA1 in lipid accumulation
Basic & Clinical Medicine 2017;37(6):869-873
ATP-binding cassette transporter A1 (ABCA1) is an membrane protein,using ATP for transferring substances,modulated by liver X receptors(LXRs), retinoic X receptors(RXRs), sterol regulatory element binding proteins(SREBPs), microRNAs and other upstream modulators.ABCA1 plays an important role in multiple pathways related to lipid accumulation.Upregulating ABCA1 expression may slow-down lipid accumulation, thus offers a promising strategy for metabolic diseases.

OBJECTIVETo compare the effectiveness and safety of transurethral resection of the prostate (TURP) and transurethral enucleative resection of the prostate (TUERP) in the treatment of benign prostate hyperplasia (BPH).
METHODSA total of 630 BPH patients with indication of surgery were randomly assigned to receive TURP (n = 305) and TUERP (n = 325), respectively. There were no significant differences preoperatively in age, prostate volume, International Prostate Symptom Score (IPSS), and Qmax between the two groups (P > 0.05). The prostate resection rate, operation time, postoperative complications, and quality of life (QOL) of the patients were recorded and statistically analyzed.
RESULTSCompared with TURP, TUERP showed a significantly higher rate of prostate resection ([47.0 +/- 13.3] vs [60.1 +/- 12.3]%, P < 0.05), shorter operation time ([57.9 +/- 15.9] vs [40.4 +/- 14.2] min, P < 0.05), and shorter bladder irrigation time ([2.7 +/- 0.6] vs [2.2 + 1.1] d, P < 0.05). Significant differences were found between the pre- and post-operative levels of serum sodium and hemoglobin in the TURP group ([141.2 +/- 3.5 ] vs [136.9 +/- 4.7] mmol/L, P < 0.01; [137.6 +/- 8.8] vs [124.8 +/- 9.6] g/L, P < 0.01), but not in the TUERP group. Three months after operation, IPSS, QOL, and Qmax were all markedly improved in both groups (P < 0.01), but with no significant differences between the two groups (P >0.05).
CONCLUSIONTUERP is better than TURP in the treatment of BPH for its advantages of higher resection rate of the prostate, shorter operation time and bladder irrigation time, less intraoperative blood loss, fewer postoperative complications, and faster recovery.

To improve the precision of image registration based on corner detection, a relative position function between multiple points to determine matching points accurately. First the corners in images are detected using Harris detector, and clustering method is used to eliminate most wrong matches after coarse screening. Then the proposed relative position function is used as a criterion of precise matching. Finally the image registration process is accomplished by affine transformation. Results show that the proposed algorithm is more effective and accurate than conventional registration algorithm.

90 min, isoflurane concentration was increased or a bolus dose of fentanyl (25-50 ?g) was given i.v.. The BIS values before and during anesthesia and at extubation, emergence time, extubation time, the time between the end of operation and Aldrete anesthesia recovery score≥9, MMSE score and isoflurane consumption were recorded and compared between the two groups. Results The total amount of isoflurane consumed was 34% lower in BIS group than in control group. The average BIS values were higher and end-tidal isoflurane concentration was lower in BIS group than in control group. The time from the end of surgery to eye-opening, to extubation and Aldrete score≥9 were significantly shorter in BIS group than in control group. The MMSE score was significantly decreased at 1 h after operation as compared to the baseline score before induction of anesthesia while in control group MMSE score was still significantly decreased at 2 h after operation. Conclusion Titration of isoflurane using BIS monitoring can reduce the dose of isoflurane during operation and contribute to faster recovery from anesthesia in elderly patients undergoing intra-abdominal surgery.

Hepatic carcinomas were induced with the administration of diethyl-nitrosamine (DEN) in rats. The morphological changes of the liver tissues in the course of carcinogenesis could be divided into 3 successive stages: the nonspecific changes reacting to the drug toxicity, non-cancerous hyperplastic nodules of hepatocytes and ductular cystadenomatous lesions,and the lesions of genuine malignancy including hepatocellular carcinoma and cholangiocarcinoma.The ultrastructural alterations of hepatocellular carcinoma showed a complicate picture and were related to the differentiation of the tumor cells. In one case of cholangiocarcinoma, numerous cytoplasmic dense-core granules similar to the neurosecretary granules seen in apudoma were found in some of the tumor cells, which is postulated to be a special type of cholangiocarcinoma. On the basis of the results, Ihe histogenesis of the neoplasms after DEN administration is considered to originate from hyperplastic nodules of hepatic cells and ductular hyperplasia.

OBJECTIVETo explore therapeutic effects of Modified pinning combined with external tension band for the treatment of Gartland type III humeral supracondylar fractures in children.
METHODSFrom February 2009 to November 2010, 79 children with Gartland type III humeral supracondylar fractures were treated by modified pinning (pinning cross internal and external condyle assisted with lateral condyle) combined with external tension band (crossing needle end and hooking around) through lateral approach of elbow. There were 47 males and 32 females, with an average age of 8.7 years (ranging from 2.5 to 14 years). The time from injury to operation was 2 h to 8 d. The elbow joint function and Carrying angle were observed before and after treatment. The Flynn criteria were used to evaluate therapeutic effects.
RESULTSSixty-one patients were followed up (18 patients' data were lost) for 6-30 months (mean 13.5 months). According to Flynn criteria, 53 patients got excellent result, 7 good and 1 fair.
CONCLUSIONTreatment of child Gartland type III humeral supracondylar fractures with modified pinning combined with external tension band through lateral approach of elbow is believed to be an ideal method, which has advantages of reliable fixation, rapid recovery and less complications.
