In November 23, 2023, a patient with 9 digits traumatic crush injury by machine compression was emergently admitted to the Department of Hand and Microsurgery, Sichuan Modern Hospital. Emergency procedures included amputation the distal stumps and replantation of proximal phalanges of left ring and little fingers. Wounds in both hands were temporarily covered with bone cement. On December 4, 2023, reconstruction of 5 digits were performed. Digital defects were: Type Ⅲ defects of left index and middle fingers and right thumb and index fingers and Type IV defect of right middle finger. All 5 reconstructed digits survived. Subsequent refinements yielded favourable outcomes and all donor toes were preserved completely. At the 14-month follow-up, the reconstructed digits exhibited satisfactory appearance and length without difficulties in daily life and at work.

Objective:To evaluate the clinical efficacy of free anterolateral thigh perforator flap (ALTPF) for reconstruction of soft tissue defects in lower extremity in elderly patient.Methods:From February 2018 to August 2024, 24 elderly patients (14 males, 10 females. Age range: 70-89 years, mean age: 73.47 years) with soft tissue defects in lower extremity were treated with free ALTPFs in the Department of Hand Microsurgery, Sichuan Modern Hospital. All patients had comorbidities including chronic pulmonary diseases (10 cases), anaemia in various severity (15 cases), atherosclerosis (9 cases), diabetes mellitus (6 cases), hypertension (5 cases) and great saphenous varicose veins (4 cases). Fourteen patients were admitted to hospital though emergency department due to trauma. Of these patients, 2 underwent emergency flap transfer surgery, 12 had temporary wound coverage with negative pressure wound therapy (NPWT) or bone cement, followed by flap surgery at 3-7 days later. Ten patients with chronic wounds were admitted through outpatient clinic and underwent flap surgery at approximately 7 days after multidisciplinary team consultation and completion of preoperative preparation. A total of 15 patients received blood transfusion: 3 before the surgery, 10 in the surgery and 2 after the surgery. Defect locations were: right calf and ankle (6 cases), right foot (5 cases), left calf and ankle (10 cases) and left foot (3 cases). Defect sizes ranged from 5.0 cm×7.0 cm to 9.0 cm×30.0 cm, with exposure of tendon, bone or internal fixation. The size of ALTPFs ranged from 6.0 cm×8.0 cm to 10.0 cm×40.0 cm. All artery of flaps was end-to-end anastomosed with the recipient artery, and the vein of flaps was anastomosed with the accompanying vein by recipient artery. Donor sites were either closed directly or reconstructed with skin grafts. All patients were included in postoperative follow-up via visit of outpatient clinic or WeChat for evaluation of flap and donor sites.Results:All 24 flaps survived. Two cases presented with venous occlusion after surgery and surgical exploration discovered: 1 patient had a long-segment venous thrombosis in the recipient vein and was treated with great saphenous vein transposition for re-anastomosis; the other had a deep haematoma compressing of the flap, which was removed surgically with haemostasis. Follow-up lasted for 3 to 24 months. All donor sites healed well without local tenderness, leaving only linear or skin graft scars. The flap survived well, without infection, ulceration or necrosis. All ankle function was preserved.Conclusion:Transfer of free ALTPF is a valuable technique for treatment of soft tissue defects in lower extremity in elderly patients. Despite higher risks, satisfactory outcome can be achieved with thorough preoperative evaluation and surgical intervention, especially when the condition of a patient is stable, an early ambulation for functional recovery should be started.

Objective:To collect and analyze the quality control data of gastric cancer surgery in Jiangsu Province from 2020 to 2022,and study the role of publishing surgical quality control data in promoting the improvement of gastric cancer surgery of China. Methods:An online questionnaire was created and distributed to the members of Jiangsu Gastric Cancer Union(JSGCU).The questionnaire collected information including the basic situation of hospital,the diagnosis and treatment of early gastric cancer,advanced gastric cancer and metastatic gastric cancer,the digestive tract reconstruction,the surgical safety,the economic indicators,and so on. Results:The quality control data of gastric cancer surgery in Jiangsu Province from 2020 to 2022 were consistently collected and published.The data analysis results show that there was a gradual increase in the percent of patients with stage Ⅰ gastric cancer,reflecting the success efforts of early screening and diagnosis.Laparoscopic surgery showed a steady increase and became the mainstream approach for curative surgery of gastric cancer in Jiangsu Province.The percent of hospital with lymph node dissection≥30 was also increased.Different locations of gastric cancer exhibited specific patterns in the choice of anastomosis methods after curative surgery.The rate of grade 3 or higher complications in laparoscopic gastric cancer surgery was slightly lower than that in open surgery.For patients experiencing complications,their postoperative hospitalization duration and expenditure were significantly higher.Finally,there was a gradual increase in the proportion of hospital choosing to close the mesentery during gastric cancer surgery. Conclusion:The publication of the quality control data of gastric cancer surgery in Jiangsu Province has driven the improvement of gastric cancer surgery standards of China.

Objective To analyze the relationship between fragmented QRS(fQRS)and microalbuminuria(MAU)and serum uric acid(SUA)in patients with type 2 diabetes mellitus(T2DM).Methods From October 2022 to June 2023,245 T2DM patients diagnosed by The Department of Endocrinology,Jinhua Hospital Affiliated to Zhejiang University School of Medicine were selected and divided into fQRS group(fQRS,n=111)and T2DM group(n=134)according to ECG results.The general data,biochemical indexes,left ventricular end-diastolic diameter(LVEDd),left ventricular end-systolic diameter(LVESd),interventricular septum(IVS),left ventricular posterior wall(LVPW),left ventricular ejection fraction(LVEF),left atrial diameter(LAd),peak value ratio of mitral orifice blood flow velocity in early and late diastole(E/A)and mitral orifice blood flow velocity in early diastole were compared between the two groups.Pearson correlation analysis was used to analyze the correlation between fQRS wave and other indexes in T2DM patients,and Logistic regression analysis was used to analyze the influencing factors of fQRS.Results The prevalence rates of UACR,SUA,HbA1c and MAU in fQRS group were higher than in T2DM group(P＜0.05 or P＜0.01).LVEDd,LAd,E,E/e'and E/A>1.5 in QRS group were higher than in T2DM group(P＜0.05 or P＜0.01).Pearson correlation analysis showed that fQRS wave was positively correlated with smoking history,BMI,HbA1c,UACR,MAU,SUA,LVEDd,LAd,E/A and E/e'(P＜0.05).Logistic regression analysis showed that MAU was the influencing factor of fQRS wave in T2DM patients.Conclusions The fQRS in ECG in patients with T2DM is associated with MAU and SUA and may be an important evidence of myocardial fibrosis associated with subclinical cardiac diastolic dysfunction.

Objective:To investigate the feasibility, clinical efficacy and donor site impact of the deep inferior epigastric artery perforator flap (DIEPF) with transverse symmetrical design in reconstruction of soft tissue defects in limbs.Methods:From September 2020 to August 2023, 12 patients with soft tissue defects of limbs who agreed to flap donor site in the lower abdominal wall were treated in the Department of Hand Surgery and Microsurgery, Sichuan Modern Hospital. There were 10 females and 2 males with an average age of 58.42 years old. Defect sites: 3 in upper limbs and 9 in lower limbs. Sizes of the soft tissue defect were 8.0 cm×15.0 cm-13.0 cm×40.0 cm. CTA or CDU was used to detect the perforators of deep inferior epigastric artery and appropriate perforators were selected. The width and length of redundant skin and subcutaneous tissues in the lower abdomen were evaluated according to the "pinch and lift test". Taking into account the requirements of abdominoplasty, symmetrical bilateral DIEPFs were designed in the transverse direction on the lower abdominal wall. The sizes of the flaps were 7.5 cm×24.0 cm-13.0 cm ×42.0 cm. The harvested flaps were firstly thinned under the microscope, trimmed and shaped properly to match the profile of the wounds. Blood circulation was reconstructed with various forms of vascular anastomoses, such as internal pressurisation, connection in series and Flow-through, etc. Lower abdominal wall wound should be gradually reduced in tension according to the requirements of abdominal wall plastic surgery, and cosmetic suturing should be performed.Results:All 12 DIEPFs survived. The lower abdominal donor site healed primarily. All patients were included in postoperative follow-up for 6 to 42 (average 18.31) months. All flaps were normal in colour and soft in texture. The appearance of abdominal walls were improved, and the function was not affected, except 1 patient who underwent debulking procedure 3 months after the surgery.Conclusion:The transverse symmetrical design of a DIEPF is an ideal method for reconstruction of soft tissue defects in limbs after appropriate flap modification. It is a win-win solution for an aesthetic appearance of donor and recipient sites of the flap.

The incidence of adenocarcinoma of esophagogastric junction (AEG) is on the rise. Due to its special lesion location and biological behavior, AEG is considered as a relatively independent disease by more and more scholars, which is different from esophageal cancer or gastric cancer. AEG is anatomically located at the junction of esophagus and stomach. The lymph node metastasis of AEG can be directed to the mediastinal and abdominal. At present, the rule of lymph node metastasis of AEG is not completely clear, and the scope of lymph node dissection has not reached a consensus. The authors summarize the hot issues and clinical evidence of lymph node dissection for AEG, in order to provide references for more reasonable lymph node dissection of AEG.

Purpose: Reduced quality of life after cystectomy has made bladder preservation a popular research topic for muscle-invasive bladder cancer (MIBC). Previous research has indicated significant tumor downstaging after neoadjuvant chemotherapy (NAC). However, maximal transurethral resection of bladder tumor (TURBT) was performed before NAC to define the pathology, impacting the real evaluation of NAC. This research aimed to assess real NAC efficacy without interference from TURBT and apply combined modality therapies guided by NAC efficacy. Materials and Methods: Patients with cT2-4aN0M0 MIBC were confirmed by cystoscopic biopsy and imaging. NAC efficacy was assessed by imaging, urine cytology, and cystoscopy with multidisciplinary team discussion. Definite responders (≤ T1) underwent TURBT plus concurrent chemoradiotherapy. Incomplete responders underwent radical cystectomy or partial cystectomy if feasible. The primary endpoint was the bladder preservation rate. Results: Fifty-nine patients were enrolled, and the median age was 63 years. Patients with cT3-4 accounted for 75%. The median number of NAC cycles was three. Definite responders were 52.5%. The complete response (CR) was 10.2%, and 59.3% of patients received bladder-sparing treatments. With a median follow-up of 44.6 months, the 3-year overall survival (OS) was 72.8%. Three-year OS and relapse-free survival were 88.4% and 60.0% in the bladder-sparing group but only 74.3% and 37.5% in the cystectomy group. The evaluations of preserved bladder function were satisfactory. Conclusion After stratifying MIBC patients by NAC efficacy, definite responders achieved a satisfactory bladder-sparing rate, prognosis, and bladder function. The CR rate reflected the real NAC efficacy for MIBC. This therapy is worth verifying through multicenter research.

Objective To analyze the clinical features of intestinal infection in patients with acute leukemia (AL) after chemotherapy. Methods The data of 103 cases of AL patients after chemotherapy from January 2014 to April 2016 were retrospectively analyzed, and categorical variables were compared by using chi-square test. Results A total of 364 cycles of chemotherapy was conducted among 103 patients, of which 66 times (18.13 %) in 59 cycles occurred intestinal infections, including twice intestinal infections in one cycle of chemotherapy in 7 cases. The incidence of intestinal infection was 27.48%(36/131) in group without complete remission (CR), and 9.87%(23/233) in CR group. There was a statistical difference between the two groups (P<0.01). Repeated intestinal infections were found in 46.67%of the patients who accepted multiple cycles of chemotherapy. In the same cycle of chemotherapy, the probability of recurrence of intestinal infection after chemotherapy was 3.7 times than patients without intestinal infection occurred during chemotherapy. The incidence of intestinal infection of patients with acute lymphoblastic leukemia (ALL) after primary inducing chemotherapy was higher than that of patients with acute myelogenous leukemia (AML) (P= 0.019). The incidence of intestinal infection combined with neutropenic was 9.89 % (36/364), and the incidence of intestinal infection was 8.24 % (30/364) in neutrophils > 0.5 × 109/L. There was no significant difference (P> 0.05). After chemotherapy, some patients with intestinal infection occurred acute abdomen, with high mortality rate. Conclusions Intestinal infection may occur in the procession of chemotherapy and myelosuppression. Special attention should be paid on intestinal infection, including reduction of blood stream infection and risk factors, as well as timely intervention.
