Objective To systematically evaluate the efficacy,safety and recent curative effects of delta-shaped anastomosis in totally laparoscopic distal gastrectomy (ICBI) for gastric carcinoma.Methods Literatures in English and Chinese comparing ECBI and ICBI published up to November 2015 were searched from international and national online databases.Meta-analysis was conducted by Review Manager 5.3 soft ware.Results There are eleven studies involved,with 2020 gastric cancer patients,including,1 169 ECBI cases and 851 ICBI cases.Meta-analysis showed that there was no significant statistical differences between ECBI group and ICBI group in operative time,resection margin length,overall postoperative complications and anastomosis-related complications.(all P ＞ 0.05).When compared to ECBI,the estimated blood loss was significantly less in ICBI,and ICBI with more retrieved lymph nodes,faster recovery of gastrointestinal function,less use of painkiller and shorter postoperative hospital stay (all P ＜ 0.05).Conclusion ICBI is safe and feasible in treatment of gastric cancer,and has a good short-term effect.

Objective To explore an anatomical basis for the lateral tarsal artery pedicle flap on front and lateral compartment of leg and the feasibility of repairing skin defects on forepart of feet. Methods The branches, course and anastomosis of the lateral tarsal artery, perforator of peroneal artery up external malleolus, superficial peroneal artery were studied in 20 legs of adult cadavers.The flap was designed on these grounds. 8 cases repaired by lateral tarsal artery pedicle flap on front and lateral compartment of leg, 5 cases of skin defects on dorsum of foots, 3 cases of skin defects on footplates.The area of defect on forepart of foot was 5 cm× 4 cm-cm × 5 cm. The donor sites were resurfaced with skin grafts or sutured directly. The lateral tarsal artery, perforator of peroneal artery up external malleolus, perforator of anterior tibial artery superficial peroneal artery were anastomosed each other, formed single band blood vessel axle on lateral foot, fore external malleolus, front and lateral compartment of leg. The area of flap was 6 cm × 4 cm - 10 cm × 6 cm.Results All of the flaps survived completely. All cases were followed up, followed up 6- 12 months, averaged 8 months. The color, appearance and texture of the flaps were good, without ulcer on the flap. The patients can walk freely. Conclusion The flap on front and lateral compartment of leg should be designed according to the lateral tarsal artery. Blood supply of flap was reliable, little trauma. The flap's vessel pedicle is enough long. It could repair any defect on forepart of foots.

he donor sites of the intermediate dorsal neurocutaneous flap on the foot. Conclusion The donor sites of the dorsal artery flaps can be repaired by the intermediate dorsal neurocutaneous flaps on the foot.The method is simple, applicable, safety.

【Objective】To observe the effect of Moschus combined with Borneol on brain water content and blood-brain barrier(BBB)permeability in rat model of cerebral focal ischemia with reperfusion.【Methods】Thirty SD rats were randomized into 6 groups: sham-operation group,model group,Moschus(1 mg?kg-1?d-1)group,Borneol(3 mg?kg-1?d-1)group,Moschus with Borneol group,nimodipine(12 mg?kg-1?d-1)group.The rat model of cerebral focal ischemia with reperfusion was established with method of putting nylon monofilament in the internal carotid artery.The brain water content was evaluated by detecting the wet weight and dry weight of brain.The detection of cerebral extra-vascular Evans blue(EB)content was used to observe the changes of BBB permeability.【Results】After cerebral ischemia for 2 hours and reperfusion for 24 hours,water content and EB content in the model group increased significantly compared with the pseudo-operation group(P

BACKGROUND: Osteoporosis is a systemic bone disease characterized by decreased bone density and deterioration of bone microstructure, leading to an increased probability of fragility fractures. Once segmental bone defect occurs, it is easy to cause delayed union and nonunion. METHODS: The aim of this study is to investigate the efficacy of extracorporeal shock wave (ESW) and teriparatideloaded hydrogel (T-Gel) combined strategy on the cell activity and differentiation of osteoporosis derived bone marrow mesenchymal stem cells (OP-BMSCs) in vitro and bone regeneration in osteoporotic segmental bone defects in vivo. RESULTS: In vitro, the strategy of combining ESW and T-Gel significantly enhanced OP-BMSCs proliferation, survival, migration, and osteogenic differentiation by up-regulating the alkaline phosphatase activity, mineralization, and expression of runt-related transcription factor-2, type I collagen, osteocalcin, and osteopontin. In the segmental bone defect models of osteoporotic rabbits, MicroCT evaluation and histological observation demonstrated this ESW-combined with T-Gel injection significantly induced bone healing by enhancing the osteogenic activity of the local microenvironment in osteoporotic defects. CONCLUSION In conclusion, ESW-combined with T-Gel injection could regulate the poor osteogenic microenvironment in osteoporotic defects and show potential for enhancing fragility fractures healing.

Background: The emergence of the severe acute respiratory syndrome coronavirus 2 omicron variant has been triggering the new wave of coronavirus disease 2019 (COVID-19) globally. However, the risk factors and outcomes for radiological abnormalities in the early convalescent stage (1 month after diagnosis) of omicron infected patients are still unknown. Methods: Patients were retrospectively enrolled if they were admitted to the hospital due to COVID-19. The chest computed tomography (CT) images and clinical data obtained at baseline (at the time of the first CT image that showed abnormalities after diagnosis) and 1 month after diagnosis were longitudinally analyzed. Uni-/multi-variable logistic regression tests were performed to explore independent risk factors for radiological abnormalities at baseline and residual pulmonary abnormalities after 1 month. Results: We assessed 316 COVID-19 patients, including 47% with radiological abnormalities at baseline and 23% with residual pulmonary abnormalities at 1-month follow-up. In a multivariate regression analysis, age ≥ 50 years, body mass index ≥ 23.87, days after vaccination ≥ 81 days, lymphocyte count ≤ 1.21 × 10 -9 /L, interleukin-6 (IL-6) ≥ 10.05 pg/mL and IgG ≤ 14.140 S/CO were independent risk factors for CT abnormalities at baseline. The age ≥ 47 years, presence of interlobular septal thickening and IL-6 ≥ 5.85 pg/mL were the independent risk factors for residual pulmonary abnormalities at 1-month follow-up. For residual abnormalities group, the patients with less consolidations and more parenchymal bands at baseline could progress on CT score after 1 month. There were no significant changes in the number of involved lung lobes and total CT score during the early convalescent stage. Conclusion The higher IL-6 level was a common independent risk factor for CT abnormalities at baseline and residual pulmonary abnormalities at 1-month follow-up. There were no obvious radiographic changes during the early convalescent stage in patients with residual pulmonary abnormalities.
