Conclusions: Fast-track surgery including intervention during perioperative period is safe and effective in colorectal surgery, significantly lightening stress and improving recovery in patients after colorectal surgery.

AIM:Researches have shown that musculocutaneous flap or fascial flap could well treat refractory bedsore in a long term. This study observed the clinical experience in the treatment of sacrococcygeal ulcers. METHODS:From January 2000 to January 2006,19 patients with sacrococcygeal ulcers,who received myocutaneous flap transposition in Department of Burns and Plastic Surgery,West China Hospital of Sichuan University,were selected. The informed consent was obtained from all patients. The surgery included two stages. At the first stage,debridement and eschar excision were performed. At the second stage,the surgery was undergone after selecting the myocutaneous flap type according to the patients' age,ulcer position,and ulcer extent. Twenty-one wounds were repaired by gluteus maximus myocutaneous flaps,and the flap size was 13 cm ?11 cm-17 cm?14 cm;8 by long-head of biceps femoris flaps of 10 cm?6 cm-13 cm?6 cm. After operation,the patients were placed on turn-over bed for 14 days and followed regularly. RESULTS:All flaps survived and the wounds in 18 cases healed at the first stage. Hematocele underlying flap occurred in one patient with urinemia,and healed by dressing exchange. After a follow-up of 5 months to 3 years,no patient had a recurrence;the color and texture of the flaps were good,and he appearance was satisfactory. CONCLUSION:The technique of two period operation treatment of myocutaneous flap transposition can accelerate the healing of sacrococcygeal ulcers and improves the success rate of operation.

Objective To investigate the effect of oral intake of 10%glucose solution before surgery on the perioperative safety and postoperative insulin resistance in patients undergoing resection for gastric cancer. Methods Between March 2012 and December 2012,36 patients undergoing elective resection for gastric cancer were enrolled and randomized into three groups. Patients in group A were given 500ml of 10%glucose solution for oral intake two hours before surgery. Patients in the group B were given distilled water instead of glucose. Patients in the group C were asked to fast for 8 hours before operation. Patient′s wellbeing scores on a visual analogue scales (VAS) were recorded. Blood samples were collected to measure. Homeostasis model assessment (HOMA) was applied to assess the status of insulin resistance (HOMA-IR) and insulin sensitivity index (ISI) according to the level of blood glucose and the serum concentration of insulin. The gastric residues before anesthesia and the time of exhaustion and defecation were also recorded. Results The gastric residues were not increased significantly after the intake of 10%glucose solution (P > 0.05). Intake of 10% glucose solution before surgery relieved thirst and hunger (P < 0.01). The time of exhaustion and defecation in three groups was not significantly different (P > 0.05). The HOMA-IR levels postoperative immediately, on the first day and the third day after surgery were lower in group A than that of group B and group C (P < 0.05), but the ISI levels were higher significantly (P < 0.01). Conclusion Intake of 10%glucose solution 2 hours before surgery for gastric cancer is be safe , which can relieve preoperative thirst and hunger, and improve postoperative insulin resistance.

BACKGROUND: Evidence exists that inhibition of matrix metanoproteinase-2(MMP-2) secretion in the proliferating hernangioma tissue by transfection of adenovirus-active MMP-2(Ad-aMMP-2) cDNA would become an important means for treatment of proliferating hemangioma.OBJECTIVE: To investigate the influences of Ad-aMMP-2 cDNA transfection on human proliferating hemangioma growth in nude mice.DESIGN, TIME AND SETTING: A randomized, grouping, and controlled observation was performed in West China Hospital of Sichuan University between August 2003 and September 2004.MATERIALS: Eighteen BALB/c-nu/nu nude mice, weighing approximately 20 g, were included. Cavernous hemangioma specimen pathologically confirmed as proliferating hemangioma was resected from one 52-day-old female child patient.METHODS: The freshly reseoted human proliferating hemangioma specimen was sliced into small pieces with a size of 5 mm×4 mm×3 mm and subcutaneously implanted into the back of 18 nude mice within 1 hour to develop mouse models of hemangioma.Forty-five days after hemangioma implantation, 15 successful hemangioma nude mice were treated by intratumoral administration of adenovirus green fluorescent protein (Ad-GFP1 n = 51 Ad-GFP group), adenovirus-active MMP-2 (n = 5, Ad-aMMP-2 group), or the same amount of phosphate buffered saline (PBS1 n = 51 control group). Intratumoral administration was performed once every other day, for a total of 4 times.MAIN OUTCOME MEASURES: Observation of tumor volume and compadson of tumor necrosis area among 3 groups; detection of GFP expression in nude mouse; gross, hematoxylin-eosin staining, and transmission etectron microscope observation of tumor tissue morphology; determination of MMP-2 cDNA expression and microvascular density by immunohistochemistry; and detection of growth cycle and apoptosis of tumor cells by flow cytometry.RESULTS:①Ad-aMMP-2 could inhibit hemangioma growth in vivo, without marked adverse reactions. Tumor necrosis of different degrees was found in each group, and tumor necrosis area was significantly greater in the Ad-aMMP-2 group than in the control and Ad-GFP groups (P < 0.01). ②Histological sections displayed GFP gene expression in the Ad-GFP group. ③Gross observation results revealed relatively large tumor tissue in the control and Ad-GFP groups and relatively small tumor tissue in the Ad-aMMP-2 group. Hernatoxylin-eosin staining results showed that in the control and Ad-GFP groups, endothelial cells aggregated together in strip-shaped or lump-shaped appearance, and in the Ad-aMMP-2 group, there were many necrotic loci arranging in lamellar-shape appearance. Transmission electron microscope results revealed vascular endothelial cells with normal morphology in the control group and tumor cells with apparent nucleoli in the Ad-GFP group, while in the Ad-aMMP-2 group, some vascular endothelial cells exhibited chromatin pycnosis in the nucleus, forming apoptotic bodies.④ MMP-2 expression and microvascular density were significantly reduced in the Ad-aMMP-2 group than in the Ad-GFP and control groups (P < 0.05). ⑤The percentage of tumor cells in G0/G1 phase was significantly higher (P < 0.05), while the proliferating index was significantly decreased, in the Ad-aMMP-2 group than in the Ad-GFP and control groups. The Ad-aMMP-2 group exhibited higher apoptosis rate of tumor cells (P < 0.05), as well as more markedly increasing apoptosis index, than the control and Ad-GFP groups.CONCLUSION: It is feasible to block human proliferating hemangioma growth by transfeotion of Ad-aMMP-2 cDNA. The included mechanisms are to inhibit vascular endothelial cells to secrete MMP-21 thereby leading to local ischemia.

Objective:To explore the influence of hypercholesterolemia on the risk of chronic kidney disease (CKD) in the middle-aged and elderly population and the gender differences.Methods:The data came from the "Epidemiological Survey of Chronic Kidney Disease among Adults in Urban Communities in Henan Province". The subjects came from 20 communities in Henan Province, aged ≥45 years old. Groups were based on the quartile of total blood cholesterol level and gender. Multivariate logistic regression and Cochran-Armitage trend test were used to analyze the effect of hypercholesterolemia on the risk of CKD and its gender differences.Results:A total of 4 779 subjects were enrolled into the study, with 1 934 males (40.5%) and 2 845 females (59.5%). The age was (61.3±7.7) years old and the blood cholesterol was (5.0±1.0) mmol/L. The prevalence rates of hypercholesterolemia, albuminuria, and reduced estimated glomerular filtration rate (eGFR) were 10.7%(305/2 845), 6.4%(182/2 845) and 2.8%(79/2 845) in females and 12.7%(245/1 934), 6.9%(133/1 934) and 2.3%(45/1 934) in males respectively. Compared with Q1 group, the prevalence of reduced eGFR in females were higher in Q2 and Q4 groups (both P<0.05). Among males, the prevalence of albuminuria and reduced eGFR increased with increasing blood cholesterol quartile (Cochran-Armitage trend test Z=12.231, 8.862, both P<0.001). Multivariate logistic regression analysis showed that hypercholesterolemia was an independent influencing factor for albuminuria and reduced eGFR ( OR=1.49, 95% CI 1.08-2.07, P=0.016 and OR=1.65, 95% CI 1.03-2.65, P=0.037, respectively). In subgroup analysis of different genders, female hypercholesterolemia was an independent influencing factor for albuminuria and reduced eGFR, while male hypercholesterolemia was not an independent influencing factor ( OR=1.54, 95% CI 0.96~2.46, P=0.075; OR=1.89, 95% CI 0.93-3.89, P=0.082, respectively). Further subgroup analysis based on the interquartile range of serum cholesterol levels found that female hypercholesterolemia was an independent influencing factor for reduced eGFR in the Q2 and Q4 groups ( OR=2.35, 95% CI 1.29-7.61, P=0.003; OR=2.51, 95% CI 1.38-8.39, P=0.001). In males, hypercholesterolemia was an independent influencing factor for albuminuria in the Q2, Q3 and Q4 groups ( OR=1.80, 95% CI 1.01-3.41, P=0.047; OR=1.85, 95% CI 1.02-3.35, P=0.044; OR=2.33, 95% CI 1.33-4.33, P=0.002). Conclusions:Hypercholesterolemia is an independent risk factor for CKD in middle-aged and elderly population, and there are gender differences, which provides a new idea for clinical prevention and control of CKD.

OBJECTIVETo investigate the impact of preoperative oral liquid carbohydrate on postoperative insulin resistance (IR) in gastric cancer patients undergoing elective resection, and to examine the association of IR index (homeostasis model assessment, HOMA-IR) with tumor necrosis factor-α (TNF-α).

METHODSBetween January 2013 and September 2013, 35 patients undergoing elective resection for gastric cancer were prospectively enrolled and randomized into two groups. Patients in trial group (n=18) received oral 500 ml of 10% glucose solution two hours before surgery. Patients in control group (n=17) were asked to fast for 8-12 hours before operation. About 300 mg of rectus abdominis and subcutaneous fatty tissues was removed before the closure of abdominal wall. Blood samples were collected to measure the serum concentration of TNF-α with double antibody sandwich ELISA in perioperative period (3-hour before operation, end of operation, 1-day and 3-day after operation). HOMA-IR was calculated on preoperative 3-hour and postoperative 1-day. Western blotting was used to detect protein expression of TNF-α. Correlation of HOMA-IR with TNF-α was examined.

RESULTSHOMA-IR on the first day after surgery was not different from that at 3-hour before surgery in trial group (P=0.090), which was significantly lower than that in control group (P=0.000). In trial group, serum TNF-α at the end of operation was higher than that at 3-hour before surgery, which declined rapidly on the first day after surgery and had no significant difference compared with that on the third day after surgery. In control group, serum TNF-α at the end of operation was also higher than that before surgery, which rose to the peak on the first day after surgery and was still higher than that at 3-hour before surgery. The TNF-α protein expression in muscle tissues of trial group was higher than that of control group (P=0.001), while no significant difference was observed between two groups in adipose tissues (P=0.987). Correlation analysis showed that HOMA-IR was positively correlated with TNF-α on the first day after surgery (r=0.832, P=0.000).

CONCLUSIONOral intake of liquid carbohydrate 2 hours before surgery can reduce the level of TNF-α, which is likely to improve the postoperative insulin resistance.

Objective: In order to achieve superior aesthetic outcomes of reconstructed ear, analyze and summarize clinical therapeutic effect in completely applying expanded retroauricular flap to encapsulate cartilage scaffold in total auricular reconstruction. Methods: From January 2016 to October 2017, fifty-three congenital microtia patients were treated. A kidney-shaped tissue expander with 50 ml capacity was embedded under retroauricular skin in the first-stage. After excessive expansion to 70 ml and remaining stable for 4 weeks, secondary operation was performed to completely encapsulate cartilage scaffold with expanded retroauricular skin. Postoperative follow-up was carried out on a routine basis. Results: All patients had undergone operations successfully with primary healing of incision. Blood supply of the retroauricular flaps was excellent, and cartilage scaffolds totally survived with no infection and absorption. Satisfactory aesthetic outcome along with clear structure, reasonable symmetry and suitable auriculocephalic angle was acquired in all cases. No color aberration was observed between the front and back side of reconstructed ear. Scars of retroauricular incisions and costal cartilage harvesting incisions were unconspicuous. Conclusions Only using expansive retroauricular flap to fully cover reconstructed cartilage scaffold is reasonable and simple without skin grafting, which is worthy of more application in microtia treatment.
