Objective To investigate the effect of placing subcutaneous drain tube and preseting triclosan-coated polyglactin 910 suture with delayed suturing to incision infection after typeⅢabdominal surgery. Methords Dividing 504 patients with typeⅢincisions undergone abdominal surgery into 3 groups. The number of group A patients with thoroughly incision washing and primary triclosan-coated polyglactin 910 suture after abdominal surgery was 143. The number of group B with closed anterior rectus sheath, opened skin and subcutaneous fat with preseted triclosan-coated polyglactin 910 suture was 190. The number of group C with subcutaneous drain tube after abdominal surgery was 171. We compared the incidence rates of incision infection and the second phase debridement suture rates among the 3 groups. Results For the group A, B, C, the number of incision infection people was 11, 4, 3 and the incision infection rate was 7.69%, 2.11%and 1.75%respectively. The difference of the 3 groups incision infection rate were statistically significant (P<0.05). The incision infection rate of the group B and group C were lower than that of group A and the difference were statistically significant (P<0.016 7). There were no significant differences in second phase debridement suture rates among the 3 groups. Conclusion Preseting triclosan-coated polyglactin 910 suture with delayed incision sutue and placing subcutaneous drain tube can decrease the incision infection rates for type Ⅲpatients after abdominal surgery, but can not decrease the second phase debridement suture rates of the infectious incision.

Objective To study the appearance of MR diffusion weighted imaging in early stages of cartilage degeneration and to detect its values. Methods In 20 goat left knees, intra- articular injection of 5 units of papain was performed causing a loss of cartilage proteoglycan. Twenty right knees were used as control group. MR diffusion weighted imaging was performed at 24 hours after intra-articular injection of papain. ADC of each part of articular cartilage was measured and compared with each other. The proteoglycan content was measured biochemically and histochemicaUy. Routine MRI and DWI were performed in 100 patients with osteoarthritis and 20 healthy people. The ADC of each interested part of articular cartilage was measured and compared with each other. Results In experimental control group, the ADCav of articular cartilage was (14.2±2.3)×10-4 mm2/s. In early stages of cartilage degeneration group, the ADCav of articular cartilage was (17.5±4.2) × 10-4 mm2/s. The ADCav of the control group was lower than that of the early stages of cartilage degeneration group (t = 2.709 ; P = 0.016) . The proteloglyean content of articular cartilage was 4.22×10<'6> μg/kg in control group, and 0.82×10<'6>μg/kg in experimental group at 24 hours after injection of papain. The difference between control group and experimental group was significant (t = 2.705, P = 0.018). In healthy people, the ADCav of articular cartilage was (7.6±2. 2) × 10-4 mm2/s. In osteoarthritis group, the ADCav of articular cartilage was (10.3±4. 2) × 10-4 mm2/s. The ADCav in the healthy group was significantly lower than that in the osteoarthritis group (t = 2.609, P = 0.014). Conclusion DWI is an useful method in detecting early stages of cartilage degeneration which can not be showed on routine sequences.

AIM: To study the expression of thrombospondin-1 (TSP-1) and receptor-CD36, and investigate the relationship between tumor invasive capability and microvessel density and thrombospondin-1. METHODS: 43 hepatocellular carcinoma (HCC) cases were under investigation. Tissues from tumor, corresponding adjacent non-HCC tissue were stained with CD34 to show the MVD. TSP-1 and CD36 were examined by immunohistochemistry (SP) and RT-PCR. Relationship between clinical pathological features and above parameters was analyed. RESULTS: The staining of TSP-1 in HCC tissue is significantly lower than that in corresponding adjacent non-HCC tissue. Expression of TSP-1 was correlated to tumor thrombi, capsule, tumor invasive capability and CD36. CD36 was also correlated to tumor thrombi and tumor invasive capability. MVD was significantly higher in TSP-1, CD36 positive group than that in negative group. CONCLUSION: TSP-1 inhibits the growth, invasion and angiogenesis in HCC. TSP-1 may take effect through CD36.

BACKGROUND: Donation after cardiac death (DCD) is becoming the main source of organs for transplantation. Donor and recipient gender may play an important role in preoperative evaluation and recipient selection of transplantation. OBJECTIVE: To analyze the effect of donor and recipient gender on the recovery of renal function after DCD renal transplantation, and to further guide the selection of recipients. METHODS: The clinical data of recipients and donors of DCD kidney transplantation performed at the First Affiliated Hospital of Zhengzhou University from July 2012 to March 2015 were analyzed retrospectively. According to donor and recipient gender, the donors and recipients were divided into four groups: group A (male donor, male recipient), group B (male donor, female recipient), group C (female donor, male recipient), group D (female donor, female recipient). The renal function of the recipients was recorded at 1 and 2 weeks, 1, 3, 6, and 12 months postoperatively to compare the effect of donor and recipient gender on the recovery of renal function. RESULTS AND CONCLUSION: The serum creatinine level in the groups A and B was lower than that in the groups C and D at postoperative different time points, and there was a significant difference at 3, 6 and 12 months postoperatively (P < 0.05). The estimated glomerular filtration rate in the groups A and B was significantly higher than that in the groups C and D at postoperative different time points (P < 0.05). The serum creatinine level in the group C was significantly higher than that in the other three groups at postoperative different time points (P < 0.05). The serum creatinine level in the group A was significantly higher than that in the group B at 3, 6 and 12 months postoperatively (P < 0.05). The glomerular filtration rate in the group A was significantly higher than that in the group C at postoperative different time points (P < 0.05). The glomerular filtration rate in the group B was significantly higher than that in the group D at 12 months postoperatively (P < 0.05). These results suggest that the male donors show superior renal function to the female donors. The postoperative recovery of renal function is relatively slow when the male recipients receive a kidney of female donors. The female recipients with lower body surface area who receive the kidney of elderly male donors with poor renal function can achieve favorable clinical effects. Therefore, the gender should be used as a reference index for selecting potential recipients.

Objective:To compare the efficacy of single kidney transplantation for children from pediatric donors between body weight ≤15 kg and >15 kg.Methods:A retrospective review in 156 children with single donor kidney transplantation from August 2010 to December 2019 in the Kidney Transplantation Department of the First Affiliated Hospital of Zhengzhou University was conducted. The patients were classified into the small kidney group (pediatric donor body weight ≤15 kg) and the big kidney group (pediatric donor body weight >15 kg). In this study, 89 cases were concluded in the small kidney group and 67 cases were concluded in the big kidney group. The donor kidneys were obtained from 46 cases of small weight (≤15 kg) pediatric donors and 48 cases of large weight (>15 kg) pediatric donors. There were significant differences in age [1.00 (0.02 - 4.00) years vs. 10.00 (3.00-18.00) years], body weight [10.0 (3.4 - 15.0) kg vs. 35.0 (16.2- 35.0) kg], height [76 (50- 113) cm vs. 144 (67-172) cm], GFR [(31.50±7.46)ml/min vs. (36.79±7.00) ml/min], and renal length to diameter [(5.91±0.48) cm vs. (8.71±1.88) cm] between the small kidney group and the big kidney group ( P < 0.01). There was no significant difference between the two groups of donors in gender, cold/warm ischemia time and cause of death ( P>0.05). There were significant differences in age [(11.28±3.89) years vs. (13.86±3.56) years], body weight [(31.83±10.45)kg vs. (35.13±9.15) kg], and height [(130.02±28.56) cm vs. (143.97±16.59) cm] between recipients of the small kidney group and big kidney group ( P < 0.05). While there were no significant differences in preoperative serum creatinine level [(822.65 ± 135.04) μmol/L vs. (777.31 ± 165.40) μmol/L], HLA mismatch [(3.4 ± 1.4) site vs. (3.2±1.3) site], and primary disease between the two groups ( P > 0.05). The recovery of renal function, postoperative adverse events, postoperative children, and graft survival were compared between the two groups. Results:The renal function of the two groups of recipients returned to normal 3 months after operation. The perioperative complications in the small kidney group and the big kidney group mainly included renal delayed recovery [5.6% (5/89) vs. 7.5% (5/67), P=0.89], renal vascular embolization [3.4% (3/89) vs. 0, P=0.35], and acute rejection [2.2% (2/89) vs. 4.3% (3/67) , P=0.75]. The main cause of recipient death during the follow-up period was pulmonary infection [4.5% (4/89) vs. 6.0% (4/67) , P=0.68]. The postoperative small kidney group was followed up for an average of 30 (3-74) months. The survival rates of children in the small kidney group at the 1, 3 and 5 years after surgery were 96.6% (86/89), 91.0% (81/89) and 91.0%(81/89), while the transplanted renal survival rates were 92.1% (82/89), 86.5% (77/89) and 84.2% (75/89), respectively. The postoperative big kidney group was followed up for an average of 32 (4-89 ) months. The survival rates of children in the big kidney group were 95.5% (64/67), 94.0% (63/67) and 91.0%(61/67) in the first 1, 3 and 5 years postoperatively, while the graft survival rates were 92.5% (62/67), 83.6% (56/67) and 83.6% (56/67), respectively. The postoperative kidneys of two groups were fast-growing, and there was no significant difference between the small kidney group and the big kidney group in graft length to diameter [(9.63±0.31) cm vs. (9.75±0.71) cm] after 1 year ( P>0.05). Conclusions:The effect of single pediatric kidney transplantation for pediatric donor with body weight ≤15 kg is equivalent to that for pediatric donor with body weight >15 kg , which can be carried out clinically.
