Objective To investigate the feasibility, safety, and short-term efficacy of minimally invasive McKeown esophagectomy (MIME) in patients with locally advanced thoracic esophageal squamous cell carcinoma (TESCC) after neoadjuvant immunotherapy. Methods The clinical data of the patients with locally advanced TESCC in the First Affiliated Hospital of University of Science and Technology of China from July 2022 to March 2023 were restrospectively analyzed. They were divided into a neoadjuvant immunotherapy (NI) group and a non-neoadjuvant immunotherapy (NNI) group according to different preoperative neoadjuvant therapy. The perioperative clinical data and 3-month follow-up data were compared between the two groups. Results A total of 47 patients were collected, including 31 males and 16 females with a mean age of (67.57±7.64) years. There were 29 patients in the NI group and 18 patients in the NNI group. There were no statistical differences in baseline data, perioperative complications, short-term complications, surgical time, intraoperative bleeding, postoperative adjuvant therapy, metastasis/recurrence within 3 months, R0 resection rate, postoperative pathological staging decline, or College of American Pathologists (CAP) tumor regression grade between the two groups (P＞0.05). Conclusion Neoadjuvant immunotherapy combined with minimally invasive McKeown esophagectomy can be safely and effectively performed for patients with locally advanced TESCC without increasing operation time, intraoperative blood loss and perioperative complications.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Infectious bone defect is bone defect with infection or as a result of treatment of bone infection. It requires surgical intervention, and the treatment processes are complex and long, which include bone infection control,bone defect repair and even complex soft tissue reconstructions in some cases. Failure to achieve the goals in any step may lead to the failure of the overall treatment. Therefore, infectious bone defect has been a worldwide challenge in the field of orthopedics. Conventionally, sequestrectomy, bone grafting, bone transport, and systemic/local antibiotic treatment are standard therapies. Radical debridement remains one of the cornerstones for the management of bone infection. However, the scale of debridement and the timing and method of bone defect reconstruction remain controversial. With the clinical application of induced membrane technique, effective infection control and rapid bone reconstruction have been achieved in the management of infectious bone defect. The induced membrane technique has attracted more interests and attention, but the lack of understanding the basic principles of infection control and technical details may hamper the clinical outcomes of induced membrane technique and complications can possibly occur. Therefore, the Chinese Orthopedic Association organized domestic orthopedic experts to formulate An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique ( version 2023) according to the evidence-based method and put forward recommendations on infectious bone defect from the aspects of precise diagnosis, preoperative evaluation, operation procedure, postoperative management and rehabilitation, so as to provide useful references for the treatment of infectious bone defect with induced membrane technique.

With the widespread application of minimally invasive esophagectomy, inflatable video-assisted mediastinoscopic transhiatal esophagectomy (IVMTE) has gradually become one of the alternative surgical methods for transthoracic esophagectomy due to less trama, fewer perioperative complications and better short-term efficacy. However, there is no uniform standard for surgical methods and lymph node dissection in medical centers that perform IVMTE, which affects the standardization and further promotion of IVMTE. Therefore, on the basis of fully consulting domestic and foreign literature, our team proposed an expert consensus focusing on IVMTE, in order to standardize the clinical practice, guarantee the quality of treatment and promote the development of IMVTE.

Objective:To compare the early efficacy of proximal femoral bionic nail (PFBN) and proximal femoral nail anti-rotation (PFNA) in the treatment of intertrochanteric fracture in the elderly.Methods:A retrospective cohort study was conducted to analyze the clinical data of 45 elderly patients with intertrochanteric fracture treated at First Affiliated Hospital of Henan Polytechnic University from March 2020 to December 2021, including 13 males and 32 females; aged 70-96 years [(78.6±7.3)years]. According to the AO classification, there were 10 patients with type 31-A1, 16 type 31-A2 and 19 type 31-A3. There were 20 patients treated with PFBN (PFBN group) and 25 with PFNA (PFNA group). The operation time, intraoperaive blood loss, bone healing time, and time to full weight-bearing were compared between the two groups. The tip-apex distance, distance from tail of lag screw to lateral side of intramedllary nail, proximal femoral length and femur neck-shaft angle were compared between the two groups at day 1 postoperatively and at the last follow-up, and their amount of changes between the two time points were also measured. Harris hip score was evaluated at 3, 6 months postoperatively and at the last follow-up. Complications were observed as well.Results:All patients were followed up for 6-21 months [(14.7±3.6)months]. There were no significant differences in operation time, intraoperative blood loss and bone healing time between the two groups (all P>0.05). The time to full weight-bearing was significantly earlier in PFBN group [(7.9±1.2)weeks] than that in PFNA group [(9.1±0.9)weeks] ( P<0.05). At day 1 postoperatively and at last follow-up, the tip-apex distance was (23.4±1.7)mm and (23.3±1.6)mm in PFBN group ( P>0.05), and was (24.5±2.1)mm and (24.3±2.3)mm in PFNA group ( P>0.05); the distance from tail of lag screw to lateral side of intramedllary nail was (8.1±1.1)mm and (11.8±0.9)mm in PFBN group ( P<0.01), and was (7.7±1.0)mm and (12.6±1.6)mm in PFNA group ( P<0.01); the proximal femoral length was (91.3±1.6)mm and (88.5±2.6)mm in PFBN group ( P<0.01), and was (91.4±2.0)mm and (87.6±2.0)mm in PFNA group ( P<0.01); the femur neck-shaft angle was (127.2±2.9)°and (125.7±3.0)° in PFBN group ( P>0.05), and was (128.5±3.0)° and (127.2±3.2)° in PFNA group ( P>0.05). There were no significant differences in the above indicators between the two groups at day 1 postoperatively and at the last follow-up (all P>0.05). The amount of changes in the tip-apex distance and femur neck-shaft angle were (-0.2±0.1)mm and (-1.6±0.7)° in PFBN group, similar with (-0.2±0.2)mm and (-1.5±1.0)° in PFNA group (all P>0.05). However, the amount of changes in the distance from tail of lag screw to lateral side of intramedllary nail and proximal femoral length were (3.6±1.4)mm and (2.7±1.2)mm in PFBN group, significantly lower than (5.2±1.1)mm and (4.0±1.1)mm in PFNA group (all P<0.01). There were no significant differences in Harris hip score between the two groups at 3, 6 months postoperatively or at the last follow-up (all P>0.05). PFBN group had 1 patient with fracture displacement, 2 with compression screw backup and 2 with thigh pain. PFNA group had 1 patient with fracture displacement and 4 with thigh pain. Conclusion:For elderly patients with intertrochanteric fracture, PFBN provides not only earlier full weight-bearing, but also stronger stability of fracture fixation than PFNA.

Objective:To summarize the infective characteristics of Fournier's gangrene (FG) and evaluate the effect of negative pressure wound therapy (NPWT).Methods:A retrospective case control study was conducted to analyze the clinical data of 31 patients with FG admitted to Peking University First Hospital from May 2010 to September 2020, including 29 males and 2 females, aged 21-78 years [(55.2±2.0)years]. A total of 29 patients were caused by infectious diseases of the perianal and urinary system, and the rest two patients were caused by vulvar infection and retroperitoneal abscess. A total of 23 patients were treated with NPWT (Group A) and 8 patients were treated with conventional dressing (Group B). Characteristics of pathogen, drug-resistance rate, medical treatment and prognosis for all patients were summarized. The hospitalization duration, numbers of operation and wound healing time were compared between two groups.Results:Monomicrobial infection was identified in 14 patients, while polymicrobial infection in 15 patients, fungal infection in 1 and culture-negative in 1. Escherichia coli, Enterococcus faecalis, Enterococcus faecium, Klebsiella pneumoniae and Staphylococcus haemolyticus were the most common pathogenic bacteria. The resistance rate of gram-negative bacilli to third-generation cephalosporins was 37%. Staphylococcus haemolyticus were methicillin-resistant Staphylococcus. The carbapenem antibiotics combined with vancomycin antibiotics were used for all patients as the empirical anti-infection treatment. Three patients died, and the rest 28 patients were followed up for 3 to 12 months [(10.8±2.6)months] after discharge. All the wounds were healed well without recurrence. In Group A and Group B, the hospitalization duration was (37.4±15.0)days and (47.0±16.0)days, respectively ( P>0.05); the number of operation was 3(3, 6) times and 13(4, 17)times, respectively ( P<0.05); the wound healing time was (38.9±17.8)days and (61.8±14.2)days, respectively ( P<0.05). Conclusions:Enterobacteriaceae, Enterococcus and Staphylococcus haemolyticus are the most common pathogenic bacteria for FG, among which the proportion of drug-resistant bacteria is relatively high. NPWT is an effective adjuvant therapy for wound management with reduced operation times and short wound healing time compared to conrentional method.

ObjectiveTo investigate the efficacy and safety of Fuzheng Huayu tablets (FZHY) combined with entecavir (ETV) in the treatment of chronic hepatitis B (CHB) liver fibrosis. MethodsA total of 52 patients with CHB liver fibrosis with an Ishak stage of ≥F3 who were treated in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine and Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from April 2011 to January 2013 were enrolled and divided into FZHY combined with ETV group (combination group) and placebo combined with ETV group (control group), with 26 patients in each group, and the course of treatment was 48 weeks for both groups. Liver biopsy was performed before and after these treatment; clinical outcome was determined based on the reversal rate of Ishak stage for liver fibrosis and the improvement rate of histological activity index (HAI) for inflammation grade, and safety was evaluated based on electrocardiographic findings. Three datasets (full analysis set, per-protocol set, and safety dataset) were identified for analysis; the t-test or the Wilcoxon test was used for comparison of continuous data between two groups, and the CMH chi-square test, the chi-square test, or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsOf all 52 patients, 46 underwent the two liver biopsies before and after treatment, with 22 in the combination group and 24 in the control group. At week 48 of treatment, there was a significant difference in the proportion of patients with Ishak stage reduced by ≥1 stage between the combination group and the control group (81.8% vs 54.2%, χ2=5.297, P=0.021). There was also a significant difference in the improvement rate of HAI grade between the combination group and the control group were (59.1% vs 25.0%, χ2=6.822, P=0.009). There were no significant differences between the two groups in the incidence rates of adverse events and serious adverse events, the safety analysis of vital signs, and laboratory safety indicators (all P＞0.05). ConclusionFZHY combined with ETV has significant advantages over ETV alone in improving liver fibrosis and inflammation, and antiviral therapy combined with anti-fibrosis therapy can bring better hepatic histological improvement for CHB patients. FZHY combined with ETV has good safety in the treatment of patients with CHB liver fibrosis.

The increasing number of patients with chronic heart failure is bound to pose a serious challenge to global healthcare systems.
