Objective: To analyze the correlation between ABO blood group compatibility and the risk of early complications after liver transplantation, and to identify risk factors for clinical intervention. Methods: Clinical data of 404 liver transplant recipients and donors were collected. Based on donor-recipient ABO matching, patients were divided into three groups: ABO-Identical (ABO-Id, n=313), ABO-compatible (ABO-c, n=68), ABO-incompatible (ABO-i, n=23). Clinical data, early complications, and associated risk factors were compared. Results: Compared with the ABO-Id, ABO-c and ABO-i recipients were younger, had a higher proportion of primary biliary atresia, and more frequently received living-donor transplantation from relatives (P<0.05). Overall complication rates were: ABO-c 47.1% (32/68), ABO-i 43.5% (10/23), ABO-Id 39.3% (123/313), with no significant intergroup difference (P>0.05). Infection was the most common complication [ABO-c 30.9% (21/68), ABO-i 21.7% (5/23), ABO-Id 17.9% (56/313)]. No significant differences were found in infection, vascular/biliary or acute kidney injury/renal failure among the three groups (P>0.05). However, ABO-c group had significantly higher rates of ascites/abscess (20.6% vs 8.9%, P<0.05) and pleural effusion (14.7% vs 7.0%, P<0.05) than ABO-Id group. There was no significant difference in the incidence of complications and ABO blood group between ABO non-Identical (ABO-c and ABO-i) and Identical groups. Logistic regression analysis showed that the risk of ascites/abscess in ABO non-Identical was higher than that in ABO-Id liver transplantation (P<0.05), and the risk of ascites/abscess after ABO-c liver transplantation was 2.246 times higher than that of ABO-Id liver transplantation. The primary biliary atresia were a risk factor for postoperative ascites/abscess. Conclusion: Enhanced postoperative management is critical for ABO-nonidentical (especially ABO-compatible) recipients, and those with biliary atresia to reduce complication risks.

AIM: To compare the effectiveness of foldable capsular body(FCB)with traditional scleral buckling(SB)in the treatment of experimental retinal detachment animal models.METHODS: After successfully establishing rhegmatogenous retinal detachment(RRD)animal models, 24 New Zealand white rabbits were randomly divided into three groups(RRD models group, SB group, and FCB group), with 8 rabbits in each group. The FCB and SB groups underwent SB and FCB surgeries for the RRD animal models, while the RRD models group only consists of RRD models without any surgical intervention during the follow-up period. The follow-up duration was 3 mo. Wide-field neonatal fundus imaging system and ophthalmic B-ultrasound were used to assess the fundus conditions before and after surgery. The Icare® TONOVET Plus tonometer was utilized to evaluate intraocular pressure changes before and after surgery. The Eaton and Draize scoring systems were selected to monitor postoperative inflammatory reactions.RESULTS: The retinal reattachment rates in the FCB and SB groups were 87.5% and 75.0%, respectively, with no statistically significant difference between the groups(P>0.05). The intraocular pressure in both the FCB and SB groups increased postoperatively compared to preoperative levels(P<0.01), and there were no significant differences in intraocular pressure at any time points during the follow-up period between the groups(P>0.05). The intraocular pressure in the RRD models group remained at a low level throughout the follow-up period. The average surgical time for the FCB group was 16.87±2.29 min, which was shorter than 46.25±4.74 min in the SB group(t=-15.166, P<0.001). According to the Eaton and Draize scoring systems, the FCB group had lower grades of conjunctival hyperemia and edema in the early postoperative period compared to the SB group, indicating milder inflammatory reactions(P<0.05).CONCLUSION: Both FCB and SB are effective in treating experimental RRD. Compared to SB, FCB is simpler to operate, and also has a shorter surgical time and milder postoperative inflammatory reactions.

Objective To study the effect of spectrum irradiation combined with operative laparoscopy on inflammatory reaction and immune function in children with appendicitis.Methods 120 children with appendicitis from January 2022 to January 2023 were selected as the study subjects,randomly divided them into two groups using a random number table method:the control group(n = 60)and the study group(n = 60).The control group underwent laparoscopic minimally invasive appendectomy,and the study group underwent spectrum irradiation combined with laparoscopic minimally invasive appendectomy.The two groups compared perioperative recovery,procalcitonin(PCT),C-reactive protein(CRP)level,cellular immune function(CD4+,CD8+,and CD4+/CD8+),humoral immune function[immunoglobulin M(IgM),immunoglobulin G(IgG),C3,and C4],pain visual analogue scale(VAS),Alvarado score,and treatment effect and postoperative complication rate.Results Compared with the control group,the study group showed a significant reduction in the time to first anal exhaust and hospital stay after surgery,the differences were statistically significant(P<0.05).Compared with preoperative levels,the levels of PCT and CRP in both groups of patients increased at 12 and 24 h postoperatively,with the highest levels occurring at 12 h postoperatively;The PCT and CRP levels in the study group were lower than those in the control group at 12 and 24 h after surgery,the differences were statistically significant(P<0.05).Compared with preoperative data,the CD4+,CD8+,and CD4+/CD8+ levels decreased in both groups at 12 and 24 h postoperatively,with the lowest levels observed at 12 h postoperatively;The CD4+,CD8+,and CD4+/CD8+ levels in the study group were higher than those in the control group at 12 and 24 h after surgery,the differences were statistically significant(P<0.05).Compared with preoperative levels,the levels of IgM,IgG,C3,and C4 in both groups of patients decreased after surgery,with the lowest levels occurring 12 h after surgery;The levels of IgM,IgG,C3,and C4 in the study group were higher than those in the control group at 12 and 24 h after surgery,the differences were statistically significant(P<0.05).Compared with preoperative conditions,the VAS and Alvarado scores in both groups of patients decreased at 12 and 24 h after surgery.The VAS and Alvarado scores of the study group were lower than those of the control group at 12 and 24 h after surgery,the differences were statistically significant(P<0.05).Compared with the control group,the study group had a higher overall effective rate and a lower total incidence of complications,the differences were statistically significant(P<0.05).Conclusion Spectrum irradiation combined with operative laparoscopy can reduce postoperative inflammatory reaction,and improve immune function in children with appendicitis,shorten inflammatory reaction and immunosuppression time,reduce pain,and have a low incidence of postoperative complications,with ideal effect.

Objective:To detect gene mutations in a pedigree with dominant dystrophic epidermolysis bullosa (DDEB) .Methods:A 20-year-old male proband presented with repeated blisters, ulceration, pigmentation, scars on the limbs, and deformation of the nails/toenails after birth. There were 5 patients in the 3-generation family, and they all presented with typical skin lesions. Peripheral blood samples were obtained from 14 members of the pedigree (including the 5 patients) and 100 unrelated healthy controls. Whole-exome sequencing was performed in the proband to identify relevant mutation sites, which were then confirmed in the family by Sanger sequencing.Results:Genetic testing indicated that the proband and the other 4 patients all carried a missense mutation (c.7885G>A) in exon 107 of the COL7A1 gene, resulting in the substitution of glycine by arginine at amino acid position 2629 (p.G2629R). The mutation was identified neither in the 9 healthy relatives nor in the 100 unrelated healthy controls. The mutation co-segregated with DDEB in the family, and was not included in databases such as Pubmed, HGMD or ClinVar, suggesting it was a novel missense mutation. The amino acid encoded by this mutation may alter the structure of type Ⅶ collagen, thereby affecting its function.Conclusion:A novel missense mutation was identified in exon 107 of the COL7A1 gene in the family with DDEB, expanding the spectrum of mutations in the COL7A1 gene.

【Objective】 To establish a blood transfusion adverse event management system and apply it to adverse events management, so as to enhance the ability to identify and process reports as well as prevent adverse events. 【Methods】 According to the errors during the whole process of blood transfusion, the management information system of blood transfusion adverse events was established, and the data of adverse transfusion reactions and adverse transfusion events from 2020 to 2022 were collected according to the system requirements. The system monitoring data and statistical analysis were used to analyze the causes of errors in each link of blood transfusion, sort the incidence of each department, focus on supervising the departments with high frequency of adverse events, and propose effective rectification. 【Results】 The management system counted 51 cases of adverse reactions. The incidence of adverse reactions of plasma (43.1 %, 22/51) was higher than that of red blood cells (39.2 %, 20/51), and the number of allergic reactions was slightly higher than that of febrile non-hemolytic transfusion reaction. Among the 628 cases of adverse transfusion events, blood transport, inbound and storage (TS-A) errors accounted for the highest proportion of 46.2% (290/628), 20.9% (131/628) in post-transfusion disposal and evaluation (TS-G) and 15.8% (99/628) in pre-transfusion evaluation and transfusion application (TS-B). TS-A12 accounted for 63.8 % (185/290) in TS-A errors, which was mainly due to plasma leakage caused by extrusion during transport and the expiration of red blood cells caused by insufficient blood inventory management. TS-B errors mainly focus on the failure to fully assess the bleeding tendency of patients before surgical system surgery, resulting in no or insufficient preoperative blood preparation. Most of the TS-G errors were unqualified medical record. 【Conclusion】 Blood transfusion adverse event management system can help to identify and prevent the occurrence or recurrence of adverse events, formulate targeted rectification and preventive measures, and improve the haemovigilance ability.

Long non-coding RNA (lncRNA) is an RNA molecule that does not code to express proteins, and plays an important role in the occurrence and development of a variety of tumors. As an lncRNA, SPRY4-IT1 is highly expressed in breast cancer tissues, and can be used as an upstream and downstream regulator of breast cancer, promoting the progression of breast cancer, and is closely related to breast cancer stage and prognosis. In-depth study of the molecular mechanism associated with SPRY4-IT1 and breast cancer can provide new ideas for discovering biomarkers for early diagnosis of breast cancer, assessing disease prognosis and finding targeting sites.

Objective:To study the predictive value of Barcelona clinic liver cancer (BCLC) staging system combined with albumin-indocyanine green (ALICE) score (ALICE-BCLC) in hepatectomy for hepatocellular carcinoma, and compare it with BCLC staging system combined with Child-Pugh score (CP-BCLC).Methods:The clinical data of 311 patients with hepatocellular carcinoma who underwent hepatectomy at Jinhua Hospital Affiliated to Zhejiang University from April 2012 to June 2021 were analyzed retrospectively. There were 271 males and 40 females, with a median age of 59 years old (range 26 to 92 years old). These patients were divided into two groups based on the ALICE-BCLC: the ALICE-BCLC grade 0 group ( n=63) and the ALICE-BCLC grade A group ( n=248); and another two groups based on the CP-BCLC: the CP-BCLC grade 0 group ( n=58) and the CP-BCLC grade A group ( n=253). The clinical data, including indocyanine green retention rate at 15 min, and albumin were collected and the scores were calculated. Follow-up was conducted by combining outpatient visits with telephone calls. The survival rate was calculated by the life method, and survival curves were drawn by the Kaplan-Meier method. The multivariate Cox regression model was used to determine the main factors affecting prognosis. Weighted Kappa was used to compare consistency of the two staging systems. Results:Multivariate analysis showed that a maximum tumor diameter >5 cm, total bilirubin >18 μmol/L, major hepatectomy, CP-BCLC grade A and ALICE-BCLC grade A to be independent risk factors affecting overall survival of patients with hepatocellular carcinoma after liver resection with curative intent (all P<0.05). The median survival of patients in the CP-BCLC grade 0 group and the CP-BCLC grade A group were 43.0 and 28.0 months, respectively. There was a significant difference between the two groups ( P=0.017). The median survival of patients in the ALICE-BCLC grade 0 group and the ALICE-BCLC grade A group were 41.4 and 28.1 months, respectively. There was a significant difference between the two groups ( P=0.035). The weighted Kappa coefficient of ALICE-BCLC and CP-BCLC was 0.949, showing a strong consistency ( P<0.001). Conclusion:ALICE-BCLC showed a good predictive value for prognosis of hepatocellular carcinoma after liver resection, and it had a similar overall prognostic discrimination ability as CP-BCLC.

Objective:To investiagte the ability of albumin-indocyanine green (ALICE) score, albumin-bilirubin (ALBI) score and Child-Pugh score in predicting postoperative liver failure (PHLF) in patients with hepatocellular carcinoma, and to determine the clinical value of ALICE score.Methods:The clinical data of 397 patients with hepatocellular carcinoma who underwent hepatectomy in the Department of Hepatobiliary and Pancreatic Surgery, Jinhua Hospital Affiliated to Zhejiang University from June 2015 to June 2021 were retrospectively analyzed, including 350 males and 47 females, aged (58.9±11.2) years. Univariate and multivariate logistic regression were used to analyze the risk factors of PHLF. The predictive ability of ALICE score for PHLF was evaluated by receiver operating characteristic (ROC) curve, and compared with ALBI score and Child-Pugh score.Results:There were 74 patients with PHLF and 323 patients without PHLF. Multivariate logistic regression analysis showed that Child-Pugh score ( OR=1.630, 95% CI: 1.251-2.486, P=0.034), ALBI score ( OR=1.863, 95% CI: 1.028-3.119, P=0.049) and ALICE score ( OR=1.759, 95% CI: 1.216-3.078, P=0.038) were independent risk factors for PHLF in patients with hepatocellular carcinoma, and the risk of PHLF increased with the increase of grade. The area under the ROC curve of ALICE score predicting PHLF in patients with hepatocellular carcinoma was 0.613 (95% CI: 0.564-0.662), the area under the ALBI score was 0.612 (95% CI: 0.563-0.661), and the area under the Child-Pugh score was 0.555 (95% CI: 0.505-0.605). The ALICE score was better than the Child-Pugh score, and the difference was statistically significant ( z=2.04, P=0.041). In small liver resection patients, ALICE score was better than Child-Pugh score ( z=2.61, P=0.009). There was no significant difference betwenn ALICE score and ALBI score ( z=0.06, P=0.954). Conclusion:ALICE score can predict the occurrence of PHLF in patients with hepatocellular carcinoma, especially in patients with small liver resection, its value is similar to ALBI score, but better than Child-Pugh score.

Objective:To compare the clinical outcomes of a double purse-string and bridging technique versus duct-to-mucosal pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of patients who underwent laparoscopic pancreaticoduodenectomy using the double purse-string and bridging pancreaticojejunostomy technique versus those who underwent duct-to-mucosa pancreaticojejunostomy at the Affiliated Jinhua Hospital of Zhejiang University School of Medicine from January 2016 to August 2021 were retrospectively analyzed. Of the 93 patients who underwent laparoscopic pancreaticoduodenectomy, there were 48 males and 45 females, with age of (62±10) years old. These patients were divided into two groups: patients who underwent double purse-string and bridging pancreaticojejunostomy (the double purse-string group, n=51), and patients who underwent duct-to-mucosa pancreaticojejunostomy (the duct-to-mucosa group, n=42). The clinical data of the two groups were compared. Results:All the 93 patients underwent laparoscopic pancreaticoduodenectomy successfully, and there were no deaths within 3 months of operation. Compared with the duct-to-mucosa group, the double purse-string group had significantly shorter time of pancreaticojejunal anastomosis [(32.41±8.75) vs. (47.62±8.90) min] and time of operation [(365.75±43.74) vs. (389.07±45.31) min] (all P<0.05). The postoperative pancreatic fistula rates were 9.8% (5/51) in the double purse-string group and 7.1% (3/42) in the duct-to-mucosa group. There was no significant difference between the two groups ( P>0.05). In the double purse-string group, there were 18 patients with a pancreatic duct diameter >3 mm, and 3 of these patients developed grade B pancreatic fistula, giving a grade B pancreatic fistula rate of 16.6% (3/18). In the duct-to-mucosa group, there were 11 patients with a pancreatic duct diameter >3 mm, and no patients developed grade B pancreatic fistula, giving a pancreatic fistula rate of 0(0/11). Conclusion:Compared with the duct-to-mucosa anastomosis, the double purse string and bridging pancreaticojejunostomy was technically simpler. It shortened the time of pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy, especially for patients with a non-dilated pancreatic duct.
