Objective:To explore the application of enhanced recovery around surgery (CMERAS) by integrated Traditional Chinese Medicine & western medicine in perioperative period of laparoscopic anterior resection for rectal cancer patients.Methods:100 patients with rectal cancer who were treated by laparoscopic anterior resection in Shuguang Hospital from July 2017 to July 2019 were divided into two groups with random number table method, 50 patients in each group. The control group received enhanced recovery after surgery (ERAS) perioperative treatment and the observation group received CMERAS perioperative treatment. Both groups were treated for 7 days. The degree of intestinal cleansing during the operation and postoperative rehabilitation quality were observed of the two groups, including the time of first exhaust, hospitalization time and the incidence of complications. Serum CRP level was detected by immunoturbidimetry, serum IL-6 level was detected by chemiluminescence immunoassay and peripheral blood CD4, CD8 and CD4/CD8 were detected by flow cytometry. Adverse reactions were recorded for the two groups.Results:There was no significant difference in the degree of intestinal cleansing between the two groups during operation ( Z=-1.140, P=0.254). The first postoperative exhaust time in the observation group (29.7 ± 4.6 h vs. 36.1 ± 3.8 h, t=7.590) was earlier than that of the control group, the hospitalization time (4.2 ± 0.5 d vs. 4.7 ± 0.6 d, t=4.379) was less than that of the control group, and the incidence of complications [8.0% (4/50) vs. 30.0% (15/50), χ2=6.498] was lower than that of the control group ( P<0.01). On the third day after the operation, serum CRP (11.84 ± 4.69 mg/L vs. 23.63 ± 5.04 mg/L, t=12.106) and IL-6 (34.31 ± 5.93 ng/L vs. 44.39 ± 8.81 ng/L, t=6.714) in the observation group were lower than those in the control group ( P<0.05). CD4 levels [(37.74 ± 7.28)% vs. (33.55 ± 5.07)%, t=-3.344], CD4/CD8 ratio (1.36 ± 0.27 vs. 1.13 ± 0.22, t=-4.920) were higher than those in the control group ( P<0.01), and CD8 levels [(28.04 ± 4.68)% vs. (30.22 ± 4.04)%, t=2.487] was lower than that of the control group ( P<0.05). There were no adverse reactions in two groups during the treatment. Conclusion:CMERAS could promote the perioperative recovery of patients with rectal cancer if treated with laparoscopic anterior resection and fewer complications would occur.

OBJECTIVETo improve the diagnosis and treatment of testicular torsion.

METHODSThe clinical data of 9 cases of suspected testicular torsion were restrospectively analyzed to summarize the diagnostic experiences.

RESULTSThe 9 patients were 12-27 (mean 15) years old, 8 treated by surgery and 1 by spontaneous detorsion under anesthesia. Among them, 7 cases were proved to be testicular torsion and 1 case was acute epididymitis. Of the 7 cases of testicular torsion, 6 were found to have 180-720-degree torsion around the spermatic cord and 1 case 180-degree around the verticality of the spermatic cord. The accuracy rate of color ultrasonic examination was 87.5%.

CONCLUSIONPatients with acute scrotum pain should have color ultrasonic examination. Not all cases of the disease had testicular torsion around the spermatic cord. Emergency operation should be performed on any suspected case of testicular torsion.

BACKGROUNDIt has been known that the growth of solid tumors is dependent on angiogenesis, and neoangiogeneses of tumor become main target to control tumor growth. The aims of this study are to investigate the inhibition effect of replicate-deficient adenovirus encoding the soluble form of mouse vascular endothelial growth factor receptor 1 (sFlt1-Adv) on angiogenesis and tumor growth in established tumor model.

METHODSMouse Lewis lung cancer cells were inoculated subcutaneously into C57 mice. sFlt1-Adv, GFP-Adv and normal saline were injected twice intravenously after establishing Lewis cancer model. Diameters of tumors were measured every other day. Tumors were resected, weighed and fixed in 3% paraformadehyde. Microvessel density of tumors was determined by immunohistochemical staining with anti-CD31 antibody.

RESULTSThe planted tumor volume and weight in sFlt1-Adv group were significantly lower compared with the two controls (P < 0.01). Its inhibition rate was 71.8%. The microvessel density in sFlt1-Adv group decreased markedly compared with that of the control groups (P < 0.01).

CONCLUSIONSsFlt1-Adv can inhibit the growth of tumor through the inhibition of tumor angiogenesis. sFlt1-Adv may be potentially valuable for clinical treatment of solid tumor.

[ABSTRACT]AIM:Toinvestigatetheinteractionandthemechanismofsphingosine-1-phosphate(S1P)and phospholipid transfer protein (PLTP) in lipoprotein.METHODS:The S1P content in the plasma and lipoprotein from 10-week-old PLTP transgenic (PLTP-Tg) mice and wild-type (WT) mice (n=8 each) was assayed.The transport of S1P by PLTP was determined by S1P transfer assay.The content of specific S1P carrier, apolipoprotein M, was detected by West-ern blotting.RESULTS:Plasma S1P contents were decreased by 21.1%in PLTP-Tg mice compared with WT mice.S1P content in high-density lipoprotein ( HDL) fraction ( HDL-S1P) from PLTP-Tg mice was decreased by 35.1% compared with WT mice, whereas the S1P in low-density lipoprotein (LDL) fraction (LDL-S1P) was increased by 127.4%.The re-sults of S1P transfer assay indicated that PLTP facilitated S 1P transport from erythrocyte to recombinant liposome at 37℃in D-Hanks buffer solution .The plasma content of apolipoprotein M was not changed in PLTP-Tg mice compared with WT mice.CONCLUSION:PLTP is a key factor to maintain plasma HDL-S1P under physical condition .Overexpression of PLTP decreases the HDL-S1P but increases LDL-S1P.The mechanism might be related to the capability of PLTP on trans-ferring S1P from erythrocyte to lipoprotein.

Objective: To investigate the clinical effect of diced cartilage in correcting nasal alar base depression after cleft lip surgery. Methods: A retrospective study was conducted in 15 patients of nasal deformity after lip surgery from January 2018 to January 2019. All the patients were taken from autologous costal cartilage to reconstruct the outline of nasal malformation, and the remaining autologous costal cartilage was cut into 0.5-1.0 mm pieces and filled into the basilar lacunar space of the nasal alar by the 1 ml syringe whose anterior needle nipples was removed. The effects of visual images before and after operation were compared and analyzed by Adobe Photoshop CS6 software. The patients were followed up for 6-15 months (mean 10months). The satisfaction and complications of the patients were investigated. Results: The nasal alar base was significantly elevated and the outline of the nasal deformity was improved in 15 patients after operation. The overall effect was satisfactory and no obvious complications were found. No obvious absorption was found in the follow-up. Conclusions The application of diced cartilage to correct the nasal alar base depression after cleft lip surgery was a feasible method with important clinical value. It advanced in taking good use of the remaining cartilage and reducing the damage to both the donor and recipient area.

Dermatofibrosarcoma protuberances is a kind of borderline or potential low-grade fibrocytoma, which usually occurs in trunk and rarely in breast. One case of breast protuberans fibrosarcoma underwent wide resection, followed by immediate reconstruction with perforator flap pedicled by thoracodorsal artery. Satisfactory result was achieved. The whole process was recorded and the related articles were reviewed systemly. The diagnosis and treatment experience of protuberans fibrosarcoma were summarized.

Objective:To investigate the effect of pedicled thoracodorsal artery perforator (TDAP) flap on the repair of axillary moderate to severe scar contracture deformity.Methods:From January 2012 to January 2017, 29 patients with axillary moderate to severe scar contracture deformity were admitted to the the Second Xiangya Hospital of Central South University, including 18 females and 11 males, aged 14-42 years. There were 3 patients with cicatricial contracture deformity of bilateral axillas and 26 patients with cicatricial contracture deformity of unilateral axilla. After relevant preoperative examinations were completed and basic diseases were controlled, axillary scar was removed or released under the anesthesia of endotracheal intubation. The areas of wounds ranged from 7.5 cm×5.0 cm to 21.0 cm×8.5 cm after the operation. The pedicled TDAP flaps were used to repair the defects, which were thinned based on demand of the recipient sites before being transferred. The areas of flaps ranged from 9.0 cm×6.0 cm to 22.0 cm×10.0 cm. The donor sites were sutured directly. The status of thinned flaps, the survival of flaps after the operation and during follow-up, and the shoulder joint function during follow-up were observed.Results:Thirty-two pedicled TDAP flaps were harvested for repairing the defects. Among them, 14 flaps were transferred directly without thinning and the thickness of the flaps ranged from 9.0 mm to 15.0 mm, with average thickness of 13.6 mm.While the other 18 flaps were thinned, and the thickness of the thinned flaps ranged from 5.0 mm to 8.0 mm, with average thickness of 7.5 mm. The distal parts of 3 flaps in 3 patients showed small size of blackening or necrosis within 72 hours after the operation, and 2 of them were thinned and the other one was not. Finally, the 3 flaps were healed after hyperbaric oxygen therapy, dressing change, or other treatments. One flap occurred vein congestion 8 hours after the operation caused by pressure on the pedicle, and the color of the flap turned back to normal after the pressure was relieved. The rest of the flaps survived well. All the patients were followed up for 9 to 36 months, with an average of 18 months. All the flaps survived well, the color of the flaps was nearly the same as the recipient sites, and none of the flaps developed obvious contraction. The shoulder joint function of all patients was significantly improved compared with that before operation, with abduction angles of shoulder joints ranged from 90.0-145.0°, with an average of 130.0°.Conclusions:Pedicled TDAP flap is an relatively ideal choice for the repair of moderate to severe axillary scar contracture deformity, and better results will be achieved if the flaps are thinned to a appropriate thickness according to the condition of axillary defects.

Objective:To evaluate the effect of preoperative 3D simulation on the evaluation of rhinoplasty.Methods:From December 2017 to March 2019, patients in the Department of Burn and Plastic Surgery of the Second Xiangya Hospital of Central South University were randomly selected as the research subjects. According to whether they had received 3D simulation before surgery, they were divided into the experimental group (after 3D simulation before comprehensive surgery) and the control group (without 3D simulation before comprehensive surgery). Visual analogue scale (VAS) and Rhinoplasty Outcomes Evaluation (ROE ) questionnaires were used to evaluate the satisfaction of all patients preoperative and one month after surgery.Results:At the beginning of this study, a total of 97 cases were included, 97 cases were given questionnaires, and 60 cases were effectively recovered, 30 cases in each group.There was statistical significance in the improvement of the postoperative VAS scores between the experimental group and the control group ( P<0. 05). The mean improvement in the experimental group was (4. 10±0. 88) points, while the mean improvement in the control group was (2. 53±0. 73) points. There was statistical significance in the improvement of the postoperativeROE satisfaction scores between the two groups. The average preoperative satisfaction score of the experimental group was (29. 5±9. 7) points, which increased to (77. 3±13. 7) points after surgery. In the control group, the average satisfaction score was (30. 4±11. 3) points before surgery and increased to (62. 7±23. 4) points after surgery. Conclusions:3D simulation before nasal synthesis can improve the postoperative satisfaction of patients.VAS and ROE questionnaires are good tools for evaluating the effect of comprehensive rhinoplastic surgery.
