Objective:To evaluate the efficacy and safety of laparoscopic hepatectomy (LH) versus open hepatectomy (OH) for malignant liver tumors in unfavorable regions using propensity score matching (PSM) analysis.Methods:Clinical data of 181 patients with malignant liver tumors in unfavorable regions undergoing hepatic resection at the Department of Hepatopancreatobiliary Surgery, Affiliated Jinhua Hospital, Zhejiang University School of Medicine, between January 2013 and February 2019, including 130 males and 51 females, aged (56.4±12.5) years. Patients were divided into two groups according to surgical approach: the OH group ( n=128) and LH group ( n=53). Clinical parameters including age, gender, hepatitis B history, operative time, and postoperative complications were recorded. PSM (1∶1 nearest neighbor matching with a caliper width of 0.04) was performed using surgical approach as the dependent variable and covariates as independent variables. Survival analysis was conducted via the Kaplan-Meier method, with intergroup survival rates were compared using log-rank tests. Results:Prior to PSM, significant intergroup differences were observed in age, hepatitis B status, cirrhosis, and microvascular invasion (all P<0.05). After PSM, 74 patients (37 per group) achieved balance in baseline characteristics (all P>0.05). Post-PSM analysis revealed significantly shorter postoperative hospitalization in LH group compared to that in OH group [9(7, 10) d vs. 11(10, 13) d, P<0.05]. No perioperative mortality occurred in either group. The OH group exhibited a higher postoperative complication rate than the LH group did [37.8% (14/37) vs. 16.2% (6/37), χ2=4.39, P=0.036]. No significant differences were observed in cumulative recurrence-free survival ( χ2=0.44, P=0.508) or overall survival ( χ2<0.01, P=0.997) between groups. Conclusion:For malignant liver tumors in unfavorable regions, LH compared favourable open surgery, regarding the reduced invasiveness, shorter hospitalization, and lower complication rates, while maintaining comparable oncological outcomes. LH represents a safe and feasible surgical approach in selected cases.

We collected the positive serum of Echinococcus granulosus infection in sheep,an inter-mediate host with strong immune response,and used healthy serum as negative control,purified the serum and target protein to capture and enrich the corresponding antigen by immunoprecipita-tion,and obtained target protein-antibody-target protein complex.Mass spectrometry strategies were combined to screen and identify specific antigens associated with Echinococcus granulosus,and the proteins with the highest peptide coverage were analyzed bioinformatically using online prediction software.The results showed that 133 Echinococcus granulosus related proteins were i-dentified by IP-MS.Among them,one protein with peptide coverage≥70％was actin Ⅱ,and three proteins with peptide coverage between 30％to 40％were Ton B box domain containing protein,NADH dehydrogenase(ubiquinone)1 α-subcomplex 2(NADH dehydrogenase[ubiquinone])and lactic dehydrogenase.There were six proteins with 20％to 30％peptide coverage,namely,spli-cing factor 3B subunit 5,tumor protein D52,expressed conserved protein,NADH dehydrogenase(ubiquinone)1 alpha subcomplex 7,inosine-5'-monophosphate dehydrogenase,and aldo keto re-ductase family 1 member B4.Bioinformatics analysis revealed that actin protein has no signal pep-tide,it is probably a non-secretory protein and is subcellularly localized to the cytoskeleton,six op-timal potential antigenic epitopes are present,and the secondary and tertiary structures are consist-ently dominated by α-helices and irregular convolutions.The results indicate that immunoprecipita-tion-mass spectrometry is a high-throughput,simple,rapid and effective method for screening and identifying fine-grained Echinococcus granulosus antigens,which can provide a basis for screening specific molecules for serodiagnostic markers in intermediate host sheep and for the development of novel diagnostic techniques for hydatid diseases.

Objective:To explore the correlation between anxiety, depression, and inflammatory markers in the body fluids of patients with burning mouth syndrome (BMS), creating a preliminary assessment model based on clinical data.Methods:Forty-one BMS patients were recruited according to the predefined inclusion criteria and exclusion criteria from the Department of Oral Medicine, Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine between December 2021 and September 2023, along with 12 healthy controls. The pain intensity of the 41 patients was assessed using the visual analog scale (VAS). Meanwhile, anxiety and depression were assessed using the Zung self-rating anxiety scale (SAS) and the Zung self-rating depression scale (SDS). The concentrations of brain-derived neurotrophic factor (BDNF), interferon-γ (IFN-γ), interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor-alpha (TNF-α) in saliva and serum were measured using the Luminex 200 TM system and enzyme-linked immunosorbent assay. Statistical analyses were performed using the Chi-square test, independent samples t-test, ANOVA, Spearman′s correlation analysis, and multiple linear regression, respectively. Results:The VAS score for the 41 BMS patients was (3.56±1.90), with 48.8% (20/41) and 41.5% (17/41) of patients experiencing mild and moderate pain, respectively. Only 7.3% (3/41) of patients had severe pain. Among the 41 BMS patients, 61.0% (25/41) exhibited anxiety and/or depression, in whom 39.0% (16/41) had both anxiety and depression, 9.8% (4/41) experienced anxiety without depression, and 12.2% (5/41) had depression without anxiety. The concentrations of IFN-γ and TNF-α in the serum and saliva of BMS patients were significantly higher than those in healthy controls (all P<0.05). In contrast, the BDNF concentration in serum was significantly lower in BMS patients than in healthy participants ( P<0.01), but was significantly higher in saliva ( P<0.001). Serum TNF-α was positively correlated with IFN-γ, IL-1β, and IL-6 (β=0.803, β=0.812, β=0.592; all P<0.01), while saliva TNF-α was negatively correlated with both anxiety and depression (β=-0.325, β=-0.321; all P<0.05). SAS scores were linearly correlated with saliva TNF-α concentrations (SAS=51.374-1.154×saliva TNF-α); saliva TNF-α concentrations were linearly correlated with saliva IFN-γ and IL-1β (saliva TNF-α=2.408+0.281×saliva IFN-γ+0.002×saliva IL-1β). Conclusions:This study provides a preliminary exploration of a clinical assessment model for BMS based on inflammatory markers and psychological scores, offering an exploratory framework for further research and optimization of the model.

Objective:To investigate the surgical technique and initial outcomes of distal derotational femoral osteotomy (DDFO) combined with knee extension device reconstruction in adolescents with habitual patellar dislocation and severe lower limb torsional deformity.Methods:A retrospective study was conducted on 10 adolescent patients (12 knees) treated at Beijing Jishuitan Hospital and its Guizhou branch from June 2016 to June 2022. There were 6 males and 4 females with an average age of 12.0±1.5 years (range: 10.0-14.5 years) Surgical treatment included DDFO and knee extension device reconstruction (lateral retinacular release, medial retinacular plication, Roux-Goldthwait distal realignment, and MPFL reconstruction). Clinical outcomes were assessed using Lysholm scores, incidence of redislocation and complications, and imaging parameters (lateral patellofemoral angle, Insall-Salvati index, TT-TG distance, and femoral anteversion angle) preoperatively and at 1 year postoperatively.Results:All 12 knees were successfully operated on, with an average surgery time of 2.0±0.5 h (range 1.0-2.5 h), intraoperative blood loss of 47.1±17.1 ml (range 20-80 ml), and follow-up time of 46.2±18.7 months (range 24-72 months). The Lysholm knee score improved from 58.25±8.80 preoperatively to 89.17±5.32 at final follow-up ( t=-9.096, P<0.001) with significant difference. The lateral patellofemoral angle improved from -64.92±4.68 preoperatively to 6.08±2.27 at final follow-up ( t=39.178, P<0.001) with significant difference. The femoral anteversion angle decreased from 34.08±3.06 preoperatively to 14.50±2.65 at final follow-up ( t=16.916, P<0.001) with significant difference. No patellar redislocation, skin necrosis, wound infection, or limited joint mobility occurred during follow-up. Conclusion:DDFO combined with knee extension device reconstruction is an effective and safe treatment for adolescent habitual patellar dislocation with severe torsional deformity, resulting in significant clinical and radiographic improvement with low complication rates.

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 investigate the effects of prophylactic analgesia using erector spinae plane block (ESPB) combined with ketorolac tromethamine on postoperative analgesia and early recovery of patients undergoing laparoscopic radical gastrectomy.Methods:A prospective randomized controlled study was conducted. A total of 105 gastric cancer patients who underwent laparoscopic radical gastrectomy in Heji Hospital Affiliated to Changzhi Medical College from June 2022 to October 2023 were selected, and the patients were divided into ESPB+ketorolac tromethamine group (T group), ESPB group (C1 group), and ketorolac tromethamine group (C2 group) by using the random number table method, with 35 cases in each group. The prophylactic analgesia method was preoperative ESPB + ketorolac tromethamine in T group, preoperative ESPB in C1 group and preoperative ketorolac tromethamine in C2 group. The intraoperative sufentanil and remifentanil dosage and the postoperative resting pain visual analogue scale (VAS) score, remedial analgesia, recovery status and complication occurrence were compared among the 3 groups.Results:The baseline characteristics and intraoperative conditions of the patients in the 3 groups were compared, and the differences were not statistically significant (all P > 0.05). The intraoperative sufentanil dosage in T group was less than that in C1 and C2 groups [30 (25, 30) μg vs. 35 (30, 35) μg vs. 40 (35, 45) μg], and the difference was statistically significant ( Z = 33.03, P < 0.001); the intraoperative remifentanil dosage in T group was less than that in C1 and C2 groups [0.34 (0.30, 0.40) mg vs. 0.40 (0.30, 0.50) mg vs. 0.70 (0.60, 0.85) mg], and the difference was statistically significant ( Z = 53.84, P < 0.001). The VAS scores at 1, 6, 12, 24, 48 h after surgery in T group were lower than those in C1 and C2 groups, and the differences were statistically significant (all P < 0.001). The press number of analgesic pump in T group was less than that in C1 and C2 groups [1 (0, 2) times vs. 2 (1, 2) times vs. 4 (3, 5) times], and the difference was statistically significant ( Z = 48.10, P < 0.001). The postoperative first time of exhaust and get out of bed and days of hospital stay in T group were shorter than those in C1 and C2 groups, and the differences were statistically significant (all P < 0.001). The differences in the incidence of postoperative nausea and vomiting, dizziness, pruritus, pneumonia, and anastomotic fistula among the 3 groups were not statistically significant (all P > 0.05). None of the 3 groups experienced postoperative drowsiness, hypotension or respiratory depression. Conclusions:Prophylactic analgesia using ESPB combined with ketorolac tromethamine can effectively reduce the postoperative pain of patients undergoing laparoscopic radical gastrectomy, reduce the use of analgesic drugs, and promote the early recovery of the patients in the postoperative period without increasing the postoperative complications.

Objective:To evaluate the feasibility of " two-stitch" fashion in laparoscopic pancreaticojejunostomy (PJ) for patients with fine pancreatic duct (<3 mm).Methods:Clinical data of 32 patients with pancreatic duct diameter <3 mm undergoing laparoscopic PJ using the " two-stitch" fashion between Apr 2021 and Jun 2024 were retrospectively analyzed, including 20 males and 12 females, aged (61.2±23.7) years. Among the patients, there were 23 (71.9%) patients of periampullary tumor and 9 (28.1%) of central pancreatic tumor. 23 (71.9%) patients underwent laparoscopic pancreatoduodenectomy (LPD) and nine (28.1%) underwent laparoscopic central pancreatectomy (LCP). All patients underwent the " two-stitch" fashion of laparoscopic PJ (one stitch each on the ventral and dorsal sides of pancreas for duct-to-mucosal anastomosis). The operation time, PJ time, postoperative hospital stay, postoperative complications (pancreatic fistula, gallbladder leakage, abdominal cavity infection, etc) and mortality were recorded.Result:All patients underwent the " two stitch" laparoscopic PJ successfully, 23(71.9%) patients underwent laparoscopic pancreatoduodenectomy (LPD) and nine (28.1%) underwent laparoscopic central pancreatectomy (LCP). The operation time was (279.3±115.8) min, the PJ time was (31.9±12.2) min, and the postoperative hospital stay was (13.4±8.3) d. Grade B pancreatic fistula occurred in six cases (18.8%, four of LPD and two of LCP), delayed gastric emptying in one case of LPD (3.1%), abdominal infection in three cases (9.4%, two of LPD and one of LCP), biliary fistula in two cases (6.3%, LPD). There were no grade C pancreatic fistula. All patients with postoperative complications were managed with conservative treatment.Conclusion:Laparoscopic " two stitch" PJ for patients with fine pancreatic duct (<3 mm) is safe and feasible.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Hashimoto's thyroiditis(HT)is an autoimmune thyroid disease characterized by diffuse enlargement of thyroid gland and elevated thyroid autoantibodies.HT is closely related to emotional factors,conveyance and dispersion function of the liver,and the qi movement of the five zang organs.This paper explores the approach to the differentiation and treatment of HT based on Professor Yang Shuyu's view of regulation of both mind and body.In the view of regulation of both mind and body,the regulation of mind is to harmonize emotions,and the regulation of body refers to the conveyance and dispersion function of zang-fu organs.Based on the view of regulation of both mind and body,the pathological changes of HT are characterized by the disordered conveyance and dispersion of qi movement,and the stable phase,hyperthyroid phase,and hypothyroid phase of HT correspond to obstructed conveyance and dispersion,excessive conveyance and dispersion,and insufficient conveyance and dispersion,respectively.The emotional disorders caused by the failure of mind regulation exist throughout the disease course.Therefore,the treatment of HT can be conducted by using the therapies of unblocking,suppressing,and tonifying separately for stable phase,hyperthyroid phase,and hypothyroid phase to address the root cause,and then the conveyance and dispersion of visceral qi movement are restored.Besides,the therapeutic method of resolution is used to alleviate symptoms by removing goiter and dissipating nodules.Simultaneously,emotional regulation therapy is incorporated to achieve a comprehensive efficacy for harmonizing physique-spirit and mind-body through the regulation of emotions,conveyance and dispersion of qi movement,and visceral functions.The view of regulation of both mind and body provides new methods and approaches for traditional Chinese medicine management of HT.
