Object To optimize the process for the recovery of soyasaponins from bean product waste. Methods Conditions for the recovery were studied by orthogonal design guided by the yield of soya-saponins as determined by UV absorbance. Results The most influential factor in the recovery by refluxing was the concentration of alcohol; while in the recovery by percolation the influential factors were in the order of concentration of ethyl alcohol, amount of alcohol used and the rate of percolation.Conclusion The optimal recovery process was found to be a single reflux with eight times of 60% alcohol for 2.5 h.

Objective To explore the change of monocyte chemotactic factor-1 protein(MCP-1)and matrix metalloproteinase-9( MMP-9)of patients with coronary artery disease( CAD)following percutaneous coronary interventional( PCI). Methods Fifty patients underwent PCI procedures for CAD compromising a single coronary artery were selected as PCI group and 30 healthy individuals with normal findings by coronary angiography were selected as the control group. Plasma MCP-1 and MMP-9 were measured in all the subjects. Results The plasma MCP-1 level of patients with CAD after PCI was(19. 87 ± 5. 31)ng/ L,higher than that before operation((15. 71 ± 5. 23)ng/ L,t = 3. 95,P < 0. 01). Whereas in the control group,the MCP-1 level after coronary angiography was(13. 78 ± 5. 58)ng/ L,which was as same as that before operation (12. 42 ± 5. 39 ng/ L,P = 0. 34). Plasma MMP-9 level in the CAD patients after PCI procedures was(22. 69 ± 5. 97)mg/ L,higher than that before operation((19. 52 ± 5. 72)mg/ L,t = 2. 71,P < 0. 01). There was no significant difference in term of plasma MMP-9 level in control group befor and after operation((17. 53 ± 5. 51) mg/ L vs.(16. 69 ± 5. 42)mg/ L,P = 0. 55). Conclusion Plasma MCP-1 and MMP-9 increase in CAD patients following PCI procedures. But their roles in the vascular restenosis following the procedures need further investigation.

Objective:To explore the clinical effect of medial plantar venous flow-through flap combined with vein transplantation to repair incomplete finger amputation with circularity soft tissue defect.Methods:A retrospective analysis was performed on the clinical data of patients with incomplete finger amputation injury with circularity soft tissue defect treated by medial plantar venous flow-through flap combined with vein transplantation from January 2016 to October 2020 in Longgang Orthopedic Hospital of Shenzhen. According to the length of the arterial and venous defects of the injured finger and the area of the circular wound, a venous flap (including 2-3 veins )was designed and harvested in the medial plantar. And then two superficial veins were harvested from the donor site to repair the dominant digital artery and distal digital vein of the severed finger. One vein in the flap was bridged to repair the non-dominant digital artery of the severed finger, and the other 1-2 veins were anastomosed with the subcutaneous vein of the proximal wound. The recipient site was closed. The donor site was repaired with full-thickness skin grafting. The appearance, two-point discrimination of the flap, as well as the shape, two-point discrimination, and the extension and flexion of the finger were followed up after the operation. The evaluation was performed by the trial standard for the replantation function of amputated fingers of the Chinese Medical Association Hand Surgery Branch.Results:In this study, a total of 11 patients with thermal crush injury were enrolled, including 7 males and 4 females, aged 16-46 years old. Cyclic skin and soft tissue defect was 1.4 cm×4.5 cm - 3.2 cm×5.4 cm in size after debridement, the arterial defect was 1.6-3.5 cm in length, and the venous defect was 1.7-3.3 cm in length. The flap was 1.6 cm×4.6 cm-3.3 cm×5.5 cm in size, and the harvested vein was 1.7-3.5 cm in length. All severed fingers and flaps survived. Eleven cases were followed up 11-18 months. The appearance of flap was not swollen, and the color and texture were close to the surrounding skin. The two-point discrimination was 7-11 mm. The shape of the finger was good, the two-point discrimination was 5-8 mm, and the extension and flexion activity of the finger was good. Ultimately, the hand function of 10 cases could be rated as excellent, and 1 case could be rated as good. There was slight pigmentation in the donor area, but no ulceration or pain, and no obvious abnormality in wearing shoes, walking, or running.Conclusions:The medial plantar venous flow-through flap combined with vascular transplantation is an ideal repair method to repair incomplete finger amputation with circularity soft tissue defect. It can not only reliably rebuild the blood supply of the distal finger, but also repair the annular defect of the proximal finger. The impact on the donor site is slight.

Objective:The operative approach and steps of laparoscopic right hemicolon cancer radical resection have been standardlized and professional consensus has been reached. However, some detailed issues such as the handling of Henle's trunk and whether to preserve the right gastroepiploic vein (RGEV) still remain controversial. This study investigates the safety, feasibility, short- and long-term outcomes of preserving RGEV during laparoscopic right hemicolectomy.Methods:A retrospective cohort study was carried out. Clinical data of 92 patients undergoing laparoscopic right hemicolectomy in Taizhou People's Hospital from March 2016 to May 2018 were retrospectively analyzed. All the patients were treated with complete mesocolon resection (CME) and had complete postoperative pathological data and follow-up data. Based on the tumor location, 49 patients preserved RGEV (preservation group) and 43 did not (non-preservation group). Pathological data, postoperative complications, short- and long-term outcomes were compared between the two groups.Results:There were no significant differences in baseline data between the two groups (all P>0.05). No significant differences were found in operation time, intraoperative blood loss, unplanned reoperation, anastomotic leak, number of harvested lymph nodes, number of metastatic lymph node, and time to food intake after surgery between two groups (all P>0.05). Compared with non-preservation group, the preservation group had faster recovery of anal gas passage after operation [(3.1±1.0) days vs. (4.0±1.7) days, t=-2.787, P=0.007], shorter length of hospitalization [(11.5±1.5) days vs. (15.0±7.9) days, t=-2.823, P=0.007], and reduced the hospitalization expenses [(46 000±5000) yuan to (57 000±33 000) yuan, t=-2.076, P=0.044]. No postoperative gastroparesis (PGS) occurred in the preservation group, while 6 cases in the non-preservation group developed gastroparesis during perioperative period ( P<0.05). The median time of follow-up time was 31.8 (5.2-43.7) months. The overall survival time of the preservation group and non-preservation group was (35.4±1.8) months and (37.6±1.7) months, respectively without significant difference ( P=0.336); the disease-free survival was (32.0±2.2) months and (35.5±2.0) months, respectively without significant difference as well ( P=0.201). Conclusions:Dissection of the Henle's truck and preservation of RGEV is safe and feasible during laparoscopic right hemicolectomy, which can significantly reduce the incidence of postoperative gastroparesis, shorten the recovery time of postoperative intestinal function and hospitalization, and decrease the cost of hospitalization. The efficacy of RGEV preservation is similar to non-preservation of RGEV.
