Objective To compare the epidermal shape built by different passages of keratinocytes and its ability of proliferation and differentiation in three-dimensional conditions.Methods Different passages of keratinocytes were used to construct tissue-engineered skin.The morphology of the tissue-engineered skin was observed with HE and PAS staining,while CK1/CK10,CK5/CK14,Ki67 were detected by immunohistochemical assays.Results All the tissue-engineered skin had a significant dermoepidermal structure.The stratification of 1st and 2nd passage skins were better,and 2nd passage epidermis was thicker than that in other passages (P＜0.05).Dermoepidermal structure in collagen type Ⅳ group binded more tightly,but collagen type Ⅳ had little effect on the thickness of the epidermis (P＞0.05).In collagen type Ⅳ group PAS stain was negative,indicating type Ⅳ collagen was unable to promote the reconstruction of BM in vitro.The Ki-67 proliferation index of the 2nd keratinocyte was similar to the normal skin,the remaining passages keratinocyte proliferation gradually decreased (P＜0.05) ; the 1st and 2nd passage skins expressed CK1/CK10 and CK5/CK14.Conclusions Keratinocytes before the 3rd passage have a better ability in the proliferation and differentiation,and so they are more suitable as seed cells for tissue-engineered skin.

Objective To explore the value of intravoxel incoherent motion (IVIM) analysis in evaluation of pathological complete response (pCR) in patients with locally advanced rectal cancer (LARC) after neoadjuvant chemotherapy.Methods Totally 61 patients with pathologically proven rectal adenocarcinoma were retrospectively analyzed.All patients underwent MR scan,including multi-b DWI IVIM sequence scanning before and after neoadjuvant chemotherapy.ADC values and IVIM parameters (slow diffusion coefficient [D],fast diffusion coefficient [D*] and perfusion fraction [f]) were measured by two radiologists independently.Then the patients were divided into pCR group (n=14) and non-pCR group (n=47).Independent-samples t test was used to compare all the parameters before and after therapy,as well as the percentage changes (△ratio) between pCR and non-pCR group.Area under the curve (AUC) was used to evaluate the diagnostic performance.Results ADC (P=0.002) and D (P=0.007) values were significantly lower before therapy,while △ratio ADC (P＜0.001) and △ratio D (P =0.002) were significantly higher in pCR group compared with those in non-pCR group.D*,f and their △ratio value were not statistically different pre-chemotherapy and post-chemotherapy in both two groups (all P＞0.05).△ratio D had the highest AUC (0.786,P＜0.01).Conclusion IVIM-derived D values can help to predict and differentiate pCR of LARC after neoadjuvant chemotherapy.

Objective:To investigate the clinical value of split domino donor auxiliary liver transplantation.Methods:The retrospective and descriptive study was conducted. The clinco-pathological data of 3 liver transplantation recipients who were admitted to Nanjing Drum Tower Hospital affiliated to Nanjing University Medical School and 1 liver transplantation recipient who was admitted to external hospital in September 2018 were collected. The first case was male, aged 22 years, who was diagnosed as type II citrullinemia (CTLN2). The second case undergoing liver transplantation in external hospital was male, aged 59 years, who was diagnosed as decompensated alcoholic cirrhosis. The third case was female, aged 52 years, who was diagnosed as hepatocellular carcinoma of right lobe of liver. The fourth case was female, aged 51 years, who was diagnosed as hepatocellular carcinoma of right lobe of liver. The donor liver from a brain and cardiac death donor was split in vitro into the left liver and the right liver, in which the right liver without middle hepatic vein, and the modified piggyback liver transplantation using the left liver and the classical orthotropic liver transplantation using the right liver was conducted on the first and the second case, respectively. The original liver of the first case was split in vivo into the left liver and the right liver, and the piggyback auxiliary liver transplantation using the left liver and the piggyback auxiliary liver transplantation using the right liver was conducted on the third and the fourth case who underwent extended right hemihepatectomy, respectively.

The fourth case died of lung metastasis 19 months after operation.Conclusion:Split domino donor auxiliary liver transplantation can be used for the treatment of metabolic liver disease and advanced hepatocellular carcinoma.

Objective To estimate the curative effect of non-gastrointestinal decompression in laproscopic colorectal surgery. Methods By using the single-blind-random test and prospective study, 55 patients were divided into two groups, experimental group and matched group. The difference of operating time, gastrointestinal function recovery time, adverse effect, complication, average length of hospital stay between two groups were observed and evaluated. Results The difference of operating time, gastrointestinal function recovery time, adverse effect, complication, average length of hospital stay between two groups were not statistically significant(P>0.05). The incidence rate of sore throat and cough and expectoration difficulty after operation was significantly lower in the experimental group (the rate was respectively 16.0% vs 77.7% and 8.0% vs 50.0, P<0.05). However, The incidence rate of nausea and vomiting, abdom-inal distension was not statistically significant(P>0.05). Conclusion In the perioperative period of laproscopic colorectal surgery, non-gastrointestinal decompression appears to be security and feasible.

Objective:The composition of thrombi obtained during mechanical thrombectomy in patients with acute ischemic stroke is analyzed to investigate its relation with stroke etiology and its influence in surgical parameters and clinical prognoses.Methods:The thrombi and clinical data of 41 patients with acute ischemic stroke directly treated by mechanical thrombectomy in our hospital from January 2019 to December 2019 were collected. Hematoxylin-eosin (HE) staining was used to quantitatively analyze the composition of thrombi, and the components of thrombi in patients with different causes of stroke (large artery atherosclerosis [LAA], cardiogenic embolism [CE], and unexplained type) were compared. These patients were divided into erythrocyte-rich group (erythrocyte content>fibrin content) and fibrin-rich group (erythrocyte content0.05). Conclusion:Thrombus composition has influence in surgical parameters, but no influence in clinical prognoses.
