Objective The anterior-lateral defect of foot that lost one of the three supporting point of foot can lead to collapse of the lateral longitudinal arch, overload of the first metatarsal heads, and painful callus formation. It is meaningful to investigate the effect of reconstructing the lateral forefoot defect with pedical fibular osteoseptocutaneous flap. Methods From March 1989 to June 2008, there were 38 patients with anterior-lateral defect of foot were constructed. The supporting point with the local distal based pedical fibular osteoseptocutaneous flap was constracted. Results All the 38 flaps survived. All 38 patients had been followed up from 6 months to 10 years (mean 23.5 months) postoperatively. The constructed supporting point of the foot was functional. The patients could walk freely with no pain, and was satisfied with the operation. Assessed with the rating system for foot and ankle established by the American Orthopaedic Foot And Anke Society, 8 patients got a score above 85, 23 patients between 75 to 85, 7 patients between 60 to 75. Conclusion It is effective that transferring local distal based pedical fibular osteoseptocutaneous flap to repair the anterior-lateral defect of foot.

OBJECTIVETo study the anatomy basis for the clinical application of the adjacent horn shaped perforator fasciocutaneous flap for the reconstruction of small and medium-sized defects in the trunk area.

METHODS(1) Ten adult antiseptic cadavers (20 sides) were perfused with red latex. The skin blood supply, line of the blood vessels, branches in accordance with the distribution and crossing were observed. (2) Fifteen cases with defects in the trunk were treated with the adjacent horn shaped perforator fasciocutaneous flaps. The defects size ranged from 5 cm x 5 cm to 13 cm x 13 cm with the size of the flaps ranging from 10 cm x 6 cm to 35 cm x 15 cm.

RESULTSThe trunk skin is supplied by mainly 17 groups arteries such as thyrocervical trunk, internal thoracic artery, posterior intercostal arteries, superior epigastric artery, arteria epigastrica inferior, lumbar arteries, and so on. The perforators (diameter > 0.5 mm) numbers are about 20, 40, 24, 6, on the chest, abdomen and perineum, upper back, waist, respectively. All the flaps survived completely with primary healing both on donor and recipient sites. The flaps color, texture, function and appearance were satisfactory during the follow-up period of 1-24 months.

CONCLUSIONSThe adjacent horn shaped perforator fasciocutaneous flap should be designed flexibly. The defects in the donor sites could be closed directly without skin graft. It is an effective, easy and ideal method for the reconstruction of large defects in the trunk.

OBJECTIVETo isolate and characterize endophytic fungi from seven Dendrobium species, and detect their antimicrobial activities.

METHODFungal endophytes were isolated by strictly sterile sample preparation and fungal identification methods were based on their ITS ribosomal DNA (ITS rDNA gene) sequences. The agar well diffusion method was then employed to evaluate the antimicrobial activity against six pathogenic organisms and the phylogenetic tree of active isolates was constructed by the MEGA.

RESULTNinety-eight endophytic fungi obtained from seven Dendrobium spp., and among them twenty-four isolates, representing 11 genera and 14 species, displayed anti-microbial activities. The phylogenetic assay based on ITS-rDNA showed that 24 active isolates were sorted to 7 taxonomic orders: Hypocreales, Sordariales, Capnodiales, Eurotiales, Botryosphaeriales, Xylariales and Mucorales. The results of antimicrobial activity assay revealed that 1.02%, 10.2%, 18.4%, 1.02%, 1.02% and 10.2% of fermentation broths of 98 isolates displayed significant antimicrobial activities against E. coli, B. subtilis, S. aureus, C. albicans, C. neoformans and A. fumigatus, respectively. Four strains DL-R-3, DL-S-6, DG-R-10 and DN-S-1 displayed strong and broad antimicrobial spectrum.

CONCLUSIONEndophytic fungi associated with Dendrobium species have fungal diversity, and possess diverse antimicrobial activity.

PURPOSE: Studies have found that long noncoding RNA HEIH (lncRNA-HEIH) is upregulated and facilitates hepatocellular carcinoma tumor growth. However, its clinical significances, roles, and action mechanism in colorectal cancer (CRC) remains unidentified. MATERIALS AND METHODS: lncRNA-HEIH expression in CRC tissues and cell lines was measured by quantitative real-time polymerase chain reaction. Cell CountingKit-8, ethynyl deoxyuridine incorporation assay, terminal deoxynucleotidyl transferase dUTP nick end labeling staining, and nude mice xenografts assays were performed to investigate the roles of lncRNA-HEIH. RNA pull-down, RNA immunoprecipitation, chromatin immunoprecipitation, and luciferase reporter assays were performed to investigate the action mechanisms of lncRNA-HEIH. RESULTS: In this study, we found that lncRNA-HEIH is significantly increased in CRC tissues and cell lines. lncRNA-HEIH expression is positively associated with tumor size, invasion depth, and poor prognosis of CRC patients. Enhanced expression of lncRNA-HEIH promotes CRC cell proliferation and decreases apoptosis in vitro, and promotes CRC tumor growth in vivo. Whereas knockdown of lncRNA-HEIH inhibits CRC cell proliferation and induces apoptosis in vitro, and suppresses CRC tumor growth in vivo. Mechanistically, lncRNA-HEIH physically binds to miR-939. The interaction between lncRNA-HEIH and miR-939 damages the binding between miR-939 and nuclear factor κB (NF-κB), increases the binding of NF-κB to Bcl-xL promoter, and promotes the transcription and expression of Bcl-xL. Moreover, Bcl-xL expression is positively associatedwith lncRNA-HEIH in CRC tissues. Blocking the interaction between lncRNA-HEIH and miR-939 abolishes the effects of lncRNA-HEIH on CRC tumorigenesis. CONCLUSION: This study demonstrated that lncRNA-HEIH promotes CRC tumorigenesis through counteracting miR-939-mediated transcriptional repression of Bcl-xL, and suggested that lncRNA-HEIH may serve as a prognostic biomarker and therapeutic target for CRC.

Objective To study the anatomic basis and its clinical effects of the adjacent perforator fasciocutaneous flap in planta.Methods From October,2010 to December,2017,the work was on two fronts:① The blood supply of the flap was studied by the dissection of 5 adult lower limbs which were perfused with red emulsion.Under the magnifying glass,the source of blood supply to the pedicle perforator fasciocutaneous flap near the foot was observed,and the caliber of perforating vessels was measured by vernier caliper.② Methods based on the anatomic study,the adjacent perforator fasciocutaneous flap was designed to repair plantar defect.Eleven cases with defects in planta were treated with the flap including 5 malignant melanoma,5 refractory wound and 1 pigmented nevus.The size of defects ranged from 1.5 cm×2.0 cm to 4.0 cm ×5.0 cm with the size of the flaps ranging from 7.0 cm×3.0 cm to 13.0 cm×7.0 cm.Results Anatomical studies showed that the supply vessels of the fasciocutaneous flap near the perforator of the plantar space were plantar medial arteries.The external diameter was greater than or equal to the 0.5 mm perforating number of about 7,the average outer diameter was (0.85±0.19) mm.The medial plantar artery emits multiple branches along the running direction and forms anastomotic branches in the arch of the foot to ensure the blood supply of the flap.Eleven cases of perforator fasciocutaneous flaps survived,including 1 case of distal necrosis of small area and healed after change dressings.The follow-up results during 6-24 months showed that all patients were walking normally,with full texture and no localized dull pain.Conclusion On the basis of the extent of diseases,projected the adjacent perforator fasciocutaneous flap,the wear resistance and abrasive resistance are improved resulted from flaps with similar skin texture of defects.The donor site can be closed directly without skin graft.It is an simple and reliable method to repair medium and small-sized plantar defects.

Objective:To investigate the clinical efficacy of percutaneous vertebral-disc plasty (PVDP) in the treatment of very severe osteoporotic vertebral compression fractures (vsOVCF).Methods:A total of 26 patients with vsOVCF were treated by PVDP at Department of Spine Surgery, The Second Affiliated Hospital, Nantong University from November 2019 to August 2021. They were 8 males and 18 females with an age of (77.9±5.2) years. Fracture sites: T11 in 9 cases, T12 in 13 cases, L1 in 7 cases, and L2 in 2 cases. The loss of vertebral height exceeded 2/3 of its original height. The curative effects were evaluated by comparing the visual analogue scale (VAS), Oswestry disability index (ODI) and local kyphosis angle (LKA) at preoperation, 1 day postoperation and the last follow-up.Results:This cohort was followed up for 12(10, 15) months. No obvious neurological damage or other serious complications occurred. The VAS scores [(2.9±0.7) and (2.2±0.7) points] and ODIs [28.0%±4.8% and 16.9%±4.0%] at 1 day postoperation and the final follow-up were significantly lower than the preoperative values respectively [(6.7±0.8) points and 66.7%±6.0%], and the values at the last follow-up were significantly lower than those at 1 day postoperation ( P<0.05). The LKAs at 1 day postoperation and the last follow-up (18.1°±4.1° and 19.5°±4.4°) were significantly smaller than that before operation (32.0°±5.2°) ( P<0.05), but there was no significant difference between 1 day postoperation and the last follow-up in LKA ( P>0.05). Conclusion:PVDP is an effective surgical treatment of vsOVCF, because it can relieve pain and improve local kyphosis with satisfactory clinical outcomes.
