OBJECTIVETo summarize clinical experiences in fat particle injection auto-transplantation during the past ten years.

METHODSRetrospective analysis of 334 cases of fat particle injection auto-transplantation was done, and we suggested the correct method of liposuction and fat injection.

RESULTSIn this series, one patient (0.29%) had a complication, thirty one patients (9.38%) had lower survival of autogenous fat-transplantation.

CONCLUSIONIn order to improve the results of fat-grafting, we must adopt the correct method of liposuction and follow the right rules.

Objective:To review the incidence and treatment status of perioperative anemia in patients with gastric cancer.Methods:The clinicopathological data of gastric cancer patients who underwent surgery at Department of Gastrointestinal Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from Jan to Dec 2019 were collected. Univariate analysis and multivariate Logistic regression analysis were used to explore the risk factors of preoperative anemia in gastric cancer.Results:A total of 879 patients were included in this study. The incidence of preoperative anemia in patients with gastric cancer was 35.6%. The incidence of postoperative anemia was 63.5%. The proportion of patients with preoperative anemia receiving treatment was 17.3%, and the proportion of patients with postoperative anemia receiving treatment was 17.4%. Univariate analysis showed that age, nutritional risk screening 2002, T stage, M stage, tumor stage and lymph node metastasis were associated with preoperative anemia (all P<0.05). Multivariate Logistic regression analysis showed that age >60 years , nutritional risk screening 2002 ≥3, T 3-4 stage and M 1 stage were independent risk factors for preoperative anemia in patients with gastric cancer (all P<0.05). Conclusions:The incidence of perioperative anemia in patients with gastric cancer is high. At present, the proportion of patients with perioperative anemia receiving treatment is low. High nutritional risk, advanced age, late tumor T stage and distant metastasis are independent risk factors for preoperative anemia in patients with gastric cancer.

Objective:To explore the value of Caprini risk assessment scale and serum D-dimer in early prediction of postoperative lower extremities deep vein thrombosis (DVT) in patients with gastrointestinal malignant tumor.Methods:A total of 240 patients with gastrointestinal malignant tumors treated in Union Hospital of Tongji Medical College of Huazhong University of Science and Technology from Jan to Oct 2020 were analyzed retrospectively.Results:Caprini score was 4 in 8 cases, 5-7 in 217 cases, and 8 in 15 cases. Sixty-seven patients developed lower extremity DVT after operation. No patients with Caprini score of 4 had DVT, 57 cases (26.3%) with a score of 5-7 had DVT; 10 cases whose score were ≥8 points (66.7%) developed DVT. There was a higher incidence of lower extremity DVT in patients ≥8 points than those of 5-7 points after surgery ( P<0.01). The postoperative Caprini score of the DVT group was higher than that of the non-DVT group (6.37±1.01 vs. 5.80±0.94, t=4.108, P<0.001). D-dimer on the first day after operation in DVT group (4.08±2.27 vs. 2.01±1.04, t=7.715, P<0.001) and the level of serum D-dimer (2.93±1.81 vs. 2.30±1.21, t=2.631, P<0.001) on day 3 was higher than that in the non-DVT group. According to the ROC curve, the best cut-off value for serum D-dimer to predict lower extremity DVT on the first postoperative day was 2.84 mg/L, the sensitivity was 70.1%, the specificity was 87.3%, and the area under the curve (AUC) was 0.815. The best cut-off value of D-dimer for predicting lower limb DVT on day 3 after surgery was 1.67 mg/L, sensitivity was 85.1%, specificity was 34.7%, and AUC was 0.611. Conclusions:Patients with gastrointestinal malignant tumors have a high incidence of postoperative lower extremity DVT. When the serum D-dimer exceeds 2.84 mg/L on the first postoperative day, the likelihood of postoperative lower extremity DVT is higher.

Objective:To identify the clinical factors associated with pathological complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT) in locally advanced middle and low rectal cancer and establish a scoring system.Methods:In this retrospective analysis the clinical data of patients with locally advanced middle and low rectal cancer treated with nCRT combined with surgery at Union Hospital of Tongji Medical College, Huazhong University of Science and Technology from Jan 2016 to Jan 2020 were studied. Patients were divided into pCR group and non-pCR group. Single factor analysis and Logistic multivariate regression analysis were performed to explore pCR related factors after nCRT, and a pCR prediction scoring system was established.Results:The pCR was achieved in 33 patients (20.8%). Univariate analysis showed that the maximum thickness of the tumor≤25mm before nCRT ( P=0.046), concurrent oxaliplatin-combined intensive chemotherapy ( P=0.013), the NLR≤1.65 before nCRT ( P=0.004) and the serum CEA≤5 ng/ml before nCRT ( P=0.016) were significantly associated with pCR. In multivariate analysis, concurrent oxaliplatin-combined intensive chemotherapy, the NLR before nCRT and serum CEA before nCRT were independent related factors of pCR. The probability of pCR for patients with score of 0, 1, 2, and 3 was 42% (10/24), 30% (19/63), 5% (3/57) and 7% (1/15), respectively. The probability of pCR in patients with score≤1 point was 33% (29/87), and 6% (4/72) for score?1 point ( P?0.001). The area under the curve of the scoring system is 0.729 (95% CI: 0.638-0.820, P?0.001). Conclusions:Concurrent oxaliplatin-combined intensive chemotherapy, NLR≤1.65 before nCRT and serum CEA≤5 ng/ml before nCRT are independent predictors of pCR in locally advanced middle and low rectal cancer and the scoring system constructed in combination with above indicators can effectively predict pCR.
