The innate immune response is the first line of defense for the host against viral infections. Targeted degradation of pathogenic microorganisms through autophagy, in conjunction with pattern recognition receptors synergistically inducing the production of interferon (IFN), constitutes an important pathway for the body to resist viral infections. Rubicon, a Run domain Beclin 1-interacting and cysteine-rich domain protein, has an inhibitory effect on autophagy and IFN production. On the one hand, Rubicon, as a component of the phosphoinositide 3-kinase (PI3K) complex, interacts with different domains of vacuolar protein sorting 34 (Vps34), ultraviolet radiation resistance associated gene (UVRAG), guanosine triphosphate (GTP) kinase, and RAS oncogene family member 7 (Rab7) to mediate the inhibition of autophagy maturation; on the other hand, Rubicon inhibits the ubiquitination of nuclear factor κB essential modulator (NEMO) and the dimerization of interferon regulatory factor 3 (IRF3), thereby blocking the signal transduction related to IFN production. Research has revealed that various viruses, such as Kaposi's sarcoma-associated herpesvirus (KSHV), hepatitis B virus (HBV), Sendai virus (SeV), and hepatitis C virus (HCV), achieve innate immune evasion by regulating the expression or function of Rubicon. Rubicon is expected to be a new target for antiviral therapy.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

OBJECTIVE: To compare the accuracy and effectiveness of orthopaedic robot-assisted minimally invasive surgery versus open surgery for limb osteoid osteoma. METHODS: A clinical data of 36 patients with limb osteoid osteomas admitted between June 2016 and June 2023 was retrospectively analyzed. Among them, 16 patients underwent orthopaedic robot-assisted minimally invasive surgery (robot-assisted surgery group), and 20 patients underwent tumor resection after lotcated by C-arm X-ray fluoroscopy (open surgery group). There was no significant difference between the two groups in the gender, age, lesion site, tumor nidus diameter, and preoperative pain visual analogue scale (VAS) scores ( P>0.05). The operation time, lesion resection time, intraoperative blood loss, intraoperative fluoroscopy frequency, lesion resection accuracy, and postoperative analgesic use frequency were recorded and compared between the two groups. The VAS scores for pain severity were compared preoperatively and at 3 days and 3 months postoperatively. RESULTS: Compared with the open surgery group, the robot-assisted surgery group had a longer operation time, less intraoperative blood loss, less fluoroscopy frequency, less postoperative analgesic use frequency, and higher lesion resection accuracy ( P<0.05). There was no significant difference in lesion resection time ( P>0.05). All patients were followed up after surgery, with a follow-up period of 3-24 months (median, 12 months) in the two groups. No postoperative complication such as wound infection or fracture occurred in either group during follow-up. No tumor recurrence was observed during follow-up. The VAS scores significantly improved in both groups at 3 days and 3 months after surgery when compared with preoperative value ( P<0.05). The VAS score at 3 days after surgery was significantly lower in robot-assisted surgery group than that in open surgery group ( P<0.05). However, there was no significant difference in VAS scores at 3 months between the two groups ( P>0.05). CONCLUSION Compared with open surgery, robot-assisted resection of limb osteoid osteomas has longer operation time, but the accuracy of lesion resection improve, intraoperative blood loss reduce, and early postoperative pain is lighter. It has the advantages of precision and minimally invasive surgery.

Objective:To investigate the strategy and feasibility of surgery for iatrogenic perforation of colorectum following colonoscopic examination or treatment.Methods:A retrospectively descriptive study was conducted. Twenty-one patients aged from 35 to 84 years old from the Department of General Surgery of the First Affiliated Hospital of Nanjing Medical University between Jan. 2015 and Dec. 2020 were enrolled in this study. There were 15 male and 6 female patients with a median age of 64 years.Observation indicators included patient demographics, including sex, age, comorbidity, abdominal surgical history; findings and outcomes of colonoscopy, including purpose of colonoscopy, time to the diagnosis of perforation; findings and outcomes of surgical treatment, including perforation site, perforation size, surgical methods, postoperative complications.Results:Eight patients were found with diagnostic colonoscopic perforation, 13 patients with therapeutic perforation (2 patients with endoscopic mucosal resection, 7 patients with endoscopic submucosal dissection and 4 patients with stent placement). Thirteen perforation occurred during the procedure of colonoscopy. Eleven patients with perforation occurred in the sigmoid colon, 3 in the ascending colon, 3 in the rectum, 2 in the descending colon, 1 in the cecum and 1 in the hepatic flexure. The perforation size ranged from 0.3 cm to 10.0 cm with a high likelihood of a bigger perforation occurred in diagnostic colonoscopy than therapeutic colonoscopy. Seven patients received primary surgical repair with 3 patients receiving diversion. Four patients received direct colostomy in the perforation site. Six patients received segmental colectomy or radical resection with primary anastomosis, among them 2 patients received defunctioning ileostomy. Four patients received resection with the Hartmann procedure. Nine patients were performed with laparoscopic surgery with 3 patients converted to open surgery. Six patients developed postoperative complications, including 1 bowel leakage, 2 wound infection, 1 wound infection accompanied with abdominal infection, 1 kidney infection. One patient with hepatic flexure perforation after stent placement died from septic shock after the Hartmann procedure.Conclusion:With proper indication, the performance of optimal surgical treatment will save lives of patients with colonoscopic perforation.

Objective:To explore the curative effect of biofeedback combined with oral Liumo Decoction on functional constipation (FC) and qi constipation syndrome.Methods:According to random number table method, 120 patients with FC of qi constipation meeting inclusion criteria in Beijing Rectum Hospital were divided into two groups between January 2018 and December 2019, 60 in each group. The control group was treated with biofeedback, while the observation group was additionally treated with oral Liumo Decoction. All were treated for 4 weeks. Before and after treatment, TCM syndromes were scored and recorded. The resting anal pressure (RAP) was detected. The anal maximal contraction pressure (AMCP) was detected by forced systolic anus. In relaxation status, gas was injected into rectal balloon to record the rectal sensation threshold (RST) and rectal maximum tolerance (RMT). The levels of serum substance P and NO were detected by double-antibody sandwich ELISA and immunoturbidimetry. The adverse events were recorded, and clinical curative effect was evaluated.Results:The differences in total response rate between the observation group and the control group was statistically significant [89.3% (50/56) vs. 64.4% (38/59)] ( χ 2=9.90, P=0.002). After treatment, scores of TCM syndromes in observation group was significantly lower than that of the control group ( t=-15.36, P<0.01). After treatment, the RAP [(48.31±4.15) mmHg vs. (53.64±5.46) mmHg, t=-5.88], RST [(30.14±3.17) ml vs. (35.42±3.12) ml, t=-9.00] and RMT [(154.21±15.27) ml vs. (160.61±16.38)ml, t=-2.16] in observation group were significantly lower than those in the control group ( P<0.05), while AMCP [(156.67 ± 15.62) mmHg vs. (132.26 ± 13.21) mmHg, t=9.07] was significantly higher than that of the control group ( P<0.01). After treatment, the substance P in observation group was significantly higher than that of the control group ( t=9.08, P<0.01), while NO was significantly lower than that of the control group ( t=-6.58, P<0.01). There were no serious adverse events during treatment in either group. Conclusion:Biofeedback combined with oral Liumo Decoction can alleviate clinical symptoms, improve anorectal dynamics indexes and regulate levels of enteric neurotransmitters in patients with FC of qi constipation with safety.

Objective:To investigate the clinical value of stylized laparoscopic hemicolec-tomy for left colon cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 174 patients who underwent laparoscopic hemicolectomy for left colon cancer in the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2020 were collected. There were 106 males and 68 females, aged 59(range, 17?86)years. All patients underwent stylized laparoscopic hemicolectomy for left colon cancer. Observation indicators: (1) surgical situations; (2) postoperative complications; (3) postoperative histopathological examinations; (4) follow-up. Follow-up was conducted using outpatient examination or telephone interview to detect tumor recurrence and metastasis and survival of patients up to October 2021. Follow-up was performed once every 3 months within postoperative 2 years, once every 6 months within postoperative 2 to 5 years and once a year after postoperative 5 years, with the end point as tumor recurrence and metastasis or death of patients. Measurement data with normal distribution were represented as Mean±SD and measurement data with skewed distribution were represented as M(range) or M( Q1, Q3). Count data were described as absolute numbers or percentages. Kaplan-Meier method was used to draw survival curve and calculate survival rate. Results:(1) Surgical situations. All the 174 patients underwent stylized laparoscopic hemicolectomy for left colon cancer successfully, including 6 cases receiving preoperative enteral stent placement due to bowel obstruc-tion, 3 cases receiving defunctioning ileostomy and 1 case receiving Hartmann procedure. The operation time, volume of intraoperative blood loss, time to postoperative initial defecation and duration of postoperative hospital stay of the 174 patients were 97(80,106)minutes, 45(25,60)mL, 5(3,6)days and 7(6,8)days, respectively. (2) Postoperative complications. Twelve of the 174 patients had complications, including 4 cases with incision infection or fat liquefaction, 3 cases with anastomotic leakage, 2 cases with incomplete bowel obstruction, 1 case with abdominal hemo-rrhage, 1 case with chylous leakage and 1 case with pulmonary infection. The 2 cases with anastomotic leakage underwent ileostomy. The patient with abdominal hemorrhage underwent laparotomy to stop bleeding. One elder patient died of postoperative pulmonary infection. The other patients with complications recovered with conservative treatment. (3) Postoperative histopatho-logical examinations. Of the 174 patients, there were 27 cases in stage Ⅰ of TNM staging, 68 cases in stage Ⅱ, 77 cases in stage Ⅲ and 2 cases in stage Ⅳ. There were 9 cases with well differentiated tumor, 107 cases with moderately differentiated tumor and 58 cases with poorly differentiated tumor. The number of lymph node detected, the number of positive lymph node and tumor diameter of the 174 patients were 19(15,23), 0(0,2) and 4(3,5)cm, respectively. Of the 174 patients, there were 79 cases with lymph node metastases, 21 cases with cancerous nodules, 35 cases with vascular invasion and 29 cases with nerve invasion. (4) Follow-up. Of the 174 patients, 157 cases were followed up for 27(range, 1?70)months. Of the 157 patients who conducted follow-up, 20 cases had tumor metastasis, including 9 cases with multiple metastasis, 5 cases with liver metastasis, 4 cases with lung metastasis, 1 case with bone metastasis and 1 case with spleen metastasis. The 5-year overall survival rate and tumor free survival rate of the 157 patients were 90.9% and 80.8%, respectively.Conclusion:The stylized laparoscopic hemicolectomy for left colon cancer is safe and feasible.

Objective:To investigate the clinical characteristics and influencing factors of mortality in patients with intra-abdominal candidiasis (IAC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 203 IAC patients who were admitted to 7 medical centers from June 2018 to June 2020 were collected, including 54 cases in Sir Run Run Shaw Hospital of Zhejiang University School of Medicine, 31 cases in Fujian Medical University Union Hospital, 25 cases in Beijing Hospital, 25 cases in the First Affiliated Hospital of Xi'an Jiaotong University, 24 cases in China-Japan Friendship Hospital, 22 cases in General Hospital of Eastern Theater Command of Chinese PLA and 22 cases in Chongqing University Cancer Hospital. There were 130 males and 73 females, aged (64±15)years. Observation indicators: (1) candida infection and treatment of IAC patients; (2) analysis of influencing factors for mortality of IAC patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate and multivariate analyses were performed by Logistic regression model. Results:(1) Candida infection and treatment of IAC patients: 134 cases of candida albicans were cultured in the initial abdominal drainage fluid or intraoperative abdominal specimens of 203 patients, and 49 cases were treated with fluconazole. Of 69 cases infected with non candida albicans, 13 cases were treated with fluconazole. The resistance rate of candida albicans to fluconazole was 5.91%(12/203). Of 203 patients, there were 68 cases with infections shock, 53 cases with renal failure, 84 cases with respiratory failure and 63 cases with multiple organ failure, respectively. There were 148 of 203 patients admitted to intensive care unit for 9 days(range, 3-20 days), and the total hospital stay was 28 days(range, 17-50 days). Of 203 patients, 86 cases were cured and discharged, 50 cases were improved and transferred to local hospitals, 32 cases gave up treatment and discharged automatically, 19 cases died, 16 cases had no follow-up data. The mortality was 25.12%(51/203). (2) Analysis of influencing factors for mortality of IAC patients. Results of univariate analysis showed that acute physiology and chronic health evaluation score, sequential organ failure assessment score, the Cr, bilirubin, albumin, procalcitonin, and PLT on the first day of candida positive culture, of the lowest value in a week and the highest in a week, heart disease, diabetes, infections shock, renal failure, respiratory failure, multiple organ failure, anti-fungal therapy were the related factors for mortality of IAC patients ( t=-2.322, Z=-2.550, -2.262, -4.361, t=2.085, Z=-3.734, -5.226, -2.394, -5.542, t=3.462, Z=-4.957, -5.632, 3.670, -5.805, t=3.966, Z=-3.734, -5.727, χ2=4.071, 4.638, 27.353, 18.818, 13.199, 26.251, 13.388, P<0.05). Multivariate analysis showed that the bilirubin, procalcitonin on the first day of candida positive culture and infections shock were independent risk factors for mortality of IAC patients ( odds ratio=1.021, 1.022, 6.864, 95% confidence interval as 1.010-1.033, 1.001-1.044, 1.858-25.353, P<0.05). Conclusions:The common fungus of IAC was candida albicans, and fluconazole can be used as the initial empirical treatment. The prognosis of patients with abdominal candidiasis is poor. Bilirubin, procalcitonin on the first day of candida positive culture and infections shock are indepen-dent risk factors for mortality of IAC patients.

AIM: To observe the effects of Tangshen formula (TSF) treatment on lipid efflux and uptake in sodium palmitate (PA) induced RAW264.7 macrophages. METHODS: After 200 μmol/L PA induced RAW264.7 macrophages, TSF and PGC-1α-siRNA were given to intervene respectively. The lipid content in the cells was detected by ELISA kit; intracellular lipid droplet deposition was detected by BODIPY 493/503 and Filipin staining. Western blot and Real-time PCR were used to detect the expression of PGC-1α, LXR, ABCA1 and CD36. RESULTS: TSF diminished the levels of TC, TG and intracellular lipid droplet deposition in PA-induced RAW264.7 macrophages. Western blot and Real-time PCR analysis showed that TSF could up-regulate the expression of PGC-1α, LXR, ABCA1 and down-regulate the expression of CD36. Furthermore, silencing PCG-1α by SiRNA significantly suppressed the effects of upregulating the expression of PGC-1α, LXR and ABCA1, and downregulating the CD36 expression with TSF treatment. CONCLUSION: TSF may extenuate intracellular lipid droplet deposition in macrophages by upregulating cholesterol efflux through activating the PGC-1α/LXR/ABCA1 pathway and inhibiting lipid uptake through down-regulateing the expression of CD36.
