Signal transducer and activator of transcription 3(STAT3)is an intracellular signaling factor that plays a critical role in various cellular processes,including the growth,differentiation,apoptosis,and immune response of cells.Aberrant activation of T helper cell 17(Th17)is closely associated with the morbidity and progress of various autoimmune diseases.STAT3 participates in the pathogenesis of Sj?gren syndrome by inducing excessive proliferation and abnormal differentiation of Th17 cells and affecting lymphocyte infiltration into exocrine glands.Therefore,targeting the STAT3 signaling pathway represents a potential novel therapeutic approach for the treatment of Sj?gren syndrome.This review summarizes the research of STAT3 in the pathogenesis and progression of Sj?gren syndrome through regulating Th17 cells,focusing on current inhibitors targeting the STAT3 signaling pathway as potential therapeutic targets for Sj?gren syndrome.

A case of spinal cord abscess caused by Nocardia cyriacigeorgica is reported. The patient is an elderly man with a history of nephritic syndrome who presented with aggravating lower back pain and then gradually developed urinary retention, weakness and numbness in both lower extremities. Operative intervention was performed, and postoperative pathological findings suggested spinal cord abscess formation. Metagenomic next-generation sequencing of the cerebrospinal fluid identified Nocardia cyriacigeorgica as the causative pathogen. Although appropriate antibiotics were prescribed, the patient died 3 months later.

Abdominal hernia repair is a challenging surgery with high complication rate and recurrence rate, especially in potentially contaminated or contaminated abdominal wall hernias. The application of hernia mesh has significantly reduced the recurrence rate. However, different types of meshes have their own advantages and disadvantages. There are still controversies regarding the selection of mesh in the environment of potential contaminated and contaminated abdominal hernia repair. The biological mesh, which was once considered that have anti-infection advantages and was widely used, has not been found to reduce the infection rate in recent studies, but instead leads to a higher recurrence rate and expensive medical costs. On the contrary, synthetic mesh represented by monofilament and large mesh polypropylene mesh have achieved good results in potentially contaminated or contaminated hernia repairs recently. The emergence of new types of meshes such as absorbable synthetic mesh may be a better choice for potentially contaminated or contaminated abdominal hernia repair. This article reviews the application progress of mesh in the environment of potential contaminated and contaminated abdominal hernia repair, aiming to provide reliable evidence for the selection of mesh for these patients.

Since the development of tension-free hernia repair, the choice of mesh type and fixation mode has become a problem that surgeons must consider in operation. The selection of appropriate mesh fixation mode is of great significance to the prognosis of patients. In recent years, with the development of laparoscopic technology and hernia repair materials, new mesh types and mesh fixation techniques have been popularized in clinical practice, tack fixation and suture fixation have been less used in trans-abdominal preperitoneal hernia repair, and medical glue and self-gripping mesh have become the mainstream choice. Some scholars believe that in addition to large direct hernia, vacuum suction fixation is also a safe and effective fixation method. The best method of mesh fixation is still controversial, and the choice of intraoperative fixation methods is also to reach a unified standard. This paper reviews the advantages and disadvantages of different mesh fixation methods in trans-abdominal preperitoneal hernia repair, as well as the selection of intraoperative fixation methods, in order to provide basis for clinicians' intraoperative selection.

Objective:To explore the risk factors of chronic postoperative inguinal pain for laparoscopic trans-abdominal preperitoneal hernia repair and establish a nomogram prediction model for it.Methods:The clinical data of 576 patients who underwent laparoscopic trans-abdominal preperitoneal hernia repair for inguinal pain at the First Hospital of Lanzhou University from January 2015 to December 2020 were analyzed retrospectively. According to different postoperative outcomes, patients were divided into chronic pain group ( n=54) and non-chronic pain group ( n=522), compared two groups of patients in the material, including gender, age, BMI, smoking history, history of drinking, hypertension, diabetes, chronic bronchitis, abdominal surgery history, history of inguinal hernia, hernia type, the hernial sac size, prophylactic use of antibiotics, VAS score, mesh fixation techniques, operation time, length of stay. Measurement data with normal distribution were expressed as ( ± s) and independent sample t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M( Q1, Q3), and the Mann-Whitney U test was used for comparision between groups. Chi-square test was used to compare the measurement data of counting data.Multivariate logistic regression was used to analyze the independent risk factors for chronic postoperative inguinal pain. R software was used to establish the drawing of the nomogram prediction model, and the consistency index, calibration chart and area under the receiver operating characteristic curve was used to evaluate the predictive ability of the nomogram prediction model. Results:According to the results of the Logistic regression analysis, age≤45 years ( OR=2.202, 95% CI: 1.080-4.491), BMI≥24 kg/m 2 ( OR=2.231, 95% CI: 1.204-4.134), hernial sac≤5 cm ( OR=2.623, 95% CI: 1.309-5.257), recurrent hernia ( OR=2.769, 95% CI: 1.118-6.860), preoperative pain ( OR=4.121, 95% CI: 2.004-8.476), suture fixation ( OR=2.204, 95% CI: 1.151-4.219)and Postoperative acute pain (VAS>3) ( OR=5.814, 95% CI: 2.532-13.350) were independent risk factors for chronic postoperative inguinal pain ( P<0.05). Based upon the above independent risk factors, the nomogram prediction model was established and verified. The area under the curve of the nomogram prediction model was 0.779 (95% CI: 0.718-0.840, P<0.01). After internal verification, the concordance index value of the prediction model was 0.779. Conclusion:age≤45 years, BMI ≥24 kg/m 2, hernial sac≤5 cm, recurrent hernia, preoperative pain, suture fixation and Postoperative acute pain (VAS>3) are independent risk factors for chronic postoperative inguinal pain for laparoscopic trans-abdominal preperitoneal hernia repair, the nomogram prediction model has a good accuracy and discrimination with a high value of clinical application.

Objective    To compare the clinical effects of segmentectomy and lobectomy for ≤2 cm lung adenocarcinoma with micropapillary and solid subtype negative by intraoperative frozen sections. Methods    The patients with adenocarcinoma who received segmentectomy or lobectomy in multicenter from June 2020 to March 2021 were included. They were divided into two groups according to a random number table, including a segmentectomy group (n=119, 44 males and 75 females with an average age of 56.6±8.9 years) and a lobectomy group (n=115, 43 males and 72 females with an average of 56.2±9.5 years). The clinical data of the patients were analyzed. Results    There was no significant difference in the baseline data between the two groups (P>0.05). No perioperative death was found. There was no statistical difference in the operation time (111.2±30.0 min vs. 107.3±34.3 min), blood loss (54.2±83.5 mL vs. 40.0±16.4 mL), drainage duration (2.8±0.6 d vs. 2.6±0.6 d), hospital stay time (3.9±2.3 d vs. 3.7±1.1 d) or pathology staging (P>0.05) between the two groups. The postoperative pulmonary function analysis revealed that the mean decreased values of forced vital capacity and forced expiratory volume in one second percent predicted in the segmentectomy group were significantly better than those in the lobectomy group (0.2±0.3 L vs. 0.4±0.3 L, P=0.005; 0.3%±8.1% vs. 2.9%±7.4%, P=0.041). Conclusion    Segmentectomy is effective in protecting lungs function, which is expected to improve life quality of patients.

Inguinal hernia is one of the most common diseases in general surgery. Surgery is the only treatment. In recent years, with the emergence and popularization of tension-free hernia repair, the recurrence rate has been lower than before. Chronic Postoperative Inguinal Pain (CPIP) has gradually become the focus of research. CPIP has now become one of the important efficacy indicators for inguinal hernia surgery. The etiology of CPIP is more complicated, mainly including neuropathic pain, non-neuropathic pain, somatic pain and visceral pain. Female, young, obese, low pain control, preoperative anxiety, preoperative pain, high pain sensitivity and other patient factors, and experience of the surgeon, open hernia repair, weight patch, patch fixation, surgery Surgical factors such as post-acute pain are risk factors for CPIP. CPIP is not only a product of neuropathic and nociceptive pain, but is also affected by various factors such as psychology, emotion, cognition, and genetics. Therefore, detailed medical history, physical examination, and correct pain and quality of life assessment tools are essential for the diagnosis of CPIP is very necessary. The treatment of CPIP should follow certain steps. The first choice is anticipatory treatment, drug treatment, psychological and behavioral treatment, physical therapy and other conservative treatments and interventional treatments, If the pain relief is not obvious after 6 months to 1 year by the above methods, surgical treatment is considered. So far, preventive analgesia and standardized surgery are the most important means to improve the prognosis of patients.

Enhanced recovery after surgery (ERAS) is a systematic approach to care that optimizes perioperative management, improves clinical outcomes, and reduces healthcare costs. ERAS has been introduced into abdominal hernia repair in recent years. Preoperative management was optimized through health education, smoking cessation, weight control, blood glucose and pain management, infection and thrombosis prophylaxis. And prevention of hypothermia, standardized anesthesia management, fluid replacement control, minimally invasive operation, controlled catheter placement and other intraoperative management optimization measures. And multi-mode analgesia, early postoperative activity, recovery of gastrointestinal function and control of blood glucose and other postoperative management optimization measures effectively reduced the incidence of complications such as surgical site infection, alleviated the pain of patients, and shortened the hospital stay. ERAS factors such as perioperative pain management, early postoperative activity, and recovery of gastrointestinal function are the key to shorten hospital stay and improve prognosis during abdominal wall hernia repair. ERAS can be used safely and effectively for abdominal hernia repair.

Objective:To identify the risk factors for preoperative full stomach in the patients undergoing emergency surgery.Methods:American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients of both sexes, aged≥18 yr, with body mass index ≥15 kg/m 2, scheduled for elective emergency surgery, were included.The operation bed was adjusted to 30° head-high and feet-low position.Ultrasound images of gastric antrum were observed in the right decubitus position, and the ultrasonic images were evaluated qualitatively and quantitatively.The ultrasonic image was qualitatively assessed as having empty antrum, liquid or solid.Three images were obtained during the diastolic period of gastric antrum when quantitative assessment was performed.The longest diameter (D1) and the widest diameter (D2) of the images were measured three times and averaged to calculate the cross-sectional area of gastric antrum [CSA=(D1×D2×π)/4]. The gastric volume was calculated [GV=27.0+ (14.6×CSA)-(1.28×age)]. When the result was<0, the gastric volume was 0.GV/body weight was calculated, and GV/body ≤1.5 ml/kg was considered as empty stomach.When gastric content was solid or GV/body weight>1.5 ml/kg, it was considered as full stomach.Patients were divided into 2 groups according to whether they presented with a full stomach: empty stomach group (group E) and full stomach group (group F). The patients′ fasting time, coexisting diseases and types of operation were recorded.Multivariate logistic regression analysis was performed on the indicators with statistically significant differences between groups to identify the risk factors for preoperative full stomach in the patients undergoing emergency surgery. Results:One hundred and seventy-nine cases were finally included, with 121 cases in group E and 58 cases in group F. Compared with group E, the fasting time was <6 h, and the incidence of coexisting diabetes was increased in group F ( P<0.05). Coexisting diabetes mellitus was an independent risk factor for preoperative full stomach in the patients undergoing emergency surgery ( P<0.05), and OR (95% confidence interval) was 11.968 (2.392-59.870). Conclusion:Coexisting diabetes mellitus is an independent risk factor for preoperative full stomach in the patients undergoing emergency surgery.

Objective To improve the diagnosis and treatment of hip gouty arthritis.Methods Retrospective analysis of cases of gouty arthritis from 2014 January to 2017 March was conducted.Patients with gouty arthritis were divided into hip joint group and common joint group (without invaded hip) and hip joint group was further divided into acute group and chronic group.Clinical data of each group were compared.Results Compared with common joint group,hip joint group usually combined with obesity or previous ipsilateral hip trauma history.Male patients in hip joint group were younger and the patients with unilateral hip involvement were without obvious local swelling,heat and pain.CT scan and sonography can provide assistance for early diagnosis and operation or pathological diagnosis was needed for the confirmation when necessary.Conclusions Hip gouty arthritis lacks specific diagnostic criteria in clinic,and is easily confused with other diseases associated with hip.Therefore,the possibility of the hip gouty arthritis should be taken into consideration when the diagnosis of the hip disease is not clear.
