Objective To investigate the dietary intakes of postoperative patients with digestive malignant tumor during their recovery at home and explores the correlation of the intakes with the food nutritional knowledge of their primary family care-givers.Methods A total of 108 primary caregivers of prospective patients with digestive malignant tumors were selected for a sur-vey conducted at home from October 2022 to March 2023 in Guangzhou,from two tertiary hospitals.In this cross-sectional study,this paper investigated these caregivers using its general information questionnaire,a nutritional knowledge-attitude-behavior ques-tionnaire,and a simple dietary self-assessment tool(SDSAT).Results The SDSAT score of the patients was collected(4.16±1.22).Significant differences were observed among patients with various tumor types in terms of the recovery time at home after surgery.The total score of family primary caregivers'nutritional knowledge,attitude,and behavior was(47.64±6.97).Pearson's correlation analysis revealed a positive correlation between the knowledge of dietary guidelines and the patient's dietary intakes during home stay(r=0.285,P＜0.05).Multiple linear regression analysis revealed that caregivers'knowledge of dieta-ry guidelines significantly influenced the dietary intake of the prospective patients.Conclusion It is essential to regularly monitor the dietary intake of prospective patients at home.Medical personnel can concentrate on intervening with the patient's caregivers and encouraging them to participate in nutrition management together.This approach can improve the quality of family care and the nutritional status of the patients.

OBJECTIVE To extract the-SH active fractions(SHF)from Bubali Cornu(water buffalo horn)and evaluate its an-tipyretic activity.METHODS SHF was extracted from Bubali Cornu by SDS-DTT,and the content of native thiols(-SH)was deter-mined by Ellman reagent method.SHF was identified based on nano LC-MS/MS technology.Evaluation of antipyretic activity of SHF was based on LPS-induced fever rat model.The levels of PGE2,IL-1β,and TNF-α in plasma as well as the levels of cAMP,PGE2,and TNF-α in the hypothalamus were measured by ELISA kits.An untargeted metabolomics approach was used to further investigate the intervention of SHF on plasma metabolites in febrile rats.RESULTS SDS-DTT could effectively extract SHF from Bubali Cornu,in which the main components were type Ⅰ,type Ⅱ keratins and keratin-associated proteins,which were rich in Cys,and the ratio of-SH to protein in SHF was increased about 20 times more than that of traditional decoction.SHF could significantly decrease(P＜0.01)the body temperature which lasted for 4.5 hours.SHF could also significantly decrease the levels of PGE2,IL-1β,TNF-α and cAMP in plasma and hypothalamic.A total of 137 potentially differential metabolites were identified from plasma samples of the control and model groups,of which 31 metabolites could be dialed back after SHF administration,including lysophosphatidic acid,phosphatidyli-nositol,phosphatidic acid,triglycerides,phosphatidylcholine and so on,which were mainly involved in the glycerophospholipid meta-bolic pathway.CONCLUSION SHF has precise antipyretic effect,and the dosage of 1/10 of the aqueous extract can show its com-parable antipyretic effect,which provides the direction and basis for the basic research on the antipyretic efficacy of Bubali Cornu.

Objective:To investigate the clinical value of multiparameteric quantitative ultrasound combined with a non-invasive prediction model for assessing high-risk steatohepatitis.Methods:One hundred and ninety-four cases with metabolic-associated fatty liver disease (MAFLD) who underwent liver biopsy in Huashan Hospital, Fudan University, from June 2021 to September 2022 were selected. Shear wave elastography (SWE), shear wave dispersion (SWD) imaging, and attenuation imaging (ATI) examinations were conducted in all patients before biopsy. High-risk steatohepatitis was defined as a total activity score of ≥4 in patients with steatohepatitis, hepatocellular ballooning, and liver lobular inflammation based on pathological hepatic steatosis, inflammatory activity, and fibrosis scoring system (SAF), and fibrosis stage≥F2. Binary logistic regression analysis was used to identify the factors influencing high-risk steatohepatitis. A predictive model for diagnosing high-risk steatohepatitis was constructed using R language. The DeLong test was used to compare the area under the curve between groups. Measurement data was compared between groups using the t-test or rank-sum test, and count data were compared between groups using the χ2 test. Results:There were 46 cases (23.7%) with high-risk steatohepatitis. The quantitative ultrasound parameters included elastic modulus ( OR=2.958, 95% CI: 1.889-4.883, P<0.001), dispersion coefficient ( OR=1.786, 95% CI: 1.424-2.292, P<0.001) and attenuation coefficient ( OR=42.642, 95% CI: 3.463-640.451, P=0.004). Serological indexes of fasting blood glucose ( OR=1.196, 95% CI: 1.048-1.392, P=0.011), alanine aminotransferase ( OR=1.012, 95% CI: 1.006-1.019, P<0.001), aspartate aminotransferase ( OR=1.027, 95% CI: 1.014-1.042, P<0.001), γ-glutamyl transferase ( OR=1.008, 95% CI: 1.001-1.017, P=0.041) and HDL cholesterol ( OR=0.087, 95% CI: 0.016-0.404, P=0.003) were the factors influencing its progression. The AUCs of elastic modulus, dispersion coefficient, attenuation coefficient, multiparametric ultrasound model, serological index model, and ultrasound combined with serology model for the diagnosis of high-risk steatohepatitis were 0.764, 0.758, 0.634, 0.786, 0.773 and 0.825, respectively. The results of the DeLong test showed that the ultrasound combined with the serological model was significantly better than the serological index model and the elastic modulus, dispersion coefficient, and attenuation coefficient alone ( P=0.024, 0.027, 0.038 and <0.001). Conclusion:The combination of multiparametric quantitative ultrasound is helpful for the non-invasive diagnosis of high-risk steatohepatitis and possesses great clinical significance.

Objective:To investigate the clinical efficacy of redo rectal resection and coloanal anastomosis.Methods:The retrospective and descriptive study was conducted. The clinicopatholo-gical data of 49 patients who underwent redo rectal resection and coloanal anastomosis for the treatment of local recurrence of tumors and failure of colorectal or coloanal anastomosis after rectal resection in the Sixth Affiliated Hospital of Sun Yat-sen University from November 2012 to December 2021 were collected. There were 32 males and 17 females, aged 57(range,31-87)years. Redo rectal resection and coloanal anastomosis was performed according to the patient′s situations. Observa-tion indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distri-bution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers or percentages. Results:(1) Surgical situations. All 49 patients underwent redo rectal resection and coloanal anastomosis successfully, with the interval between the initial surgery and the reopera-tion as 14.2(7.1,24.3)months. The operation time and volume of intraoperative bold loss of 49 patients in the redo rectal resection and coloanal anastomosis was 313(251,398)minutes and 125(50,400)mL, respectively. Of the 49 patients, there were 38 cases receiving laparoscopic surgery including 12 cases with transanoscopic laparoscopic assisted surgery, 11 cases receiving open surgery including 2 cases as conversion to open surgery, there were 20 cases undergoing Bacon surgery, 14 cases undergoing Dixon surgery, 12 cases undergoing Parks surgery, 2 cases undergoing intersphincter resection and 1 case undergoing Kraske surgery, there were 20 cases undergoing rectum dragging out excision and secondary colonic anastomosis, 13 cases undergoing dragging out excision single anastomosis, 12 cases undergoing rectum dragging out excision double anastomosis, 4 cases undergoing first-stage manual anastomosis, there were 21 cases with enterostomy before surgery, 16 cases with prophylactic enterostomy after surgery, 12 cases without prophylactic enterostomy after surgery. The duration of postoperative hospital stay of 49 patients was (14±7)days. (2) Postoperative situations. Fifteen of 49 patients underwent postoperative complications, including 8 cases with grade Ⅱ Clevien-Dindo complications and 7 cases with ≥grade Ⅲ Clevien-Dindo complications. None of 49 patient underwent postoperative transferring to intensive care unit and no patient died during hospitalization. Results of postoperative histopathological examination in 23 patients with tumor local recurrence showed negative incision margin of the surgical specimen. (3) Follow-up. All 49 patients underwent post-operative follow-up of 90 days. There were 42 cases undergoing redo rectal resection and coloanal anastomosis successfully and 7 cases failed. Of the 37 patients with enterostomy, 20 cases failed in closing fistula, and 17 cases succeed. There were 46 patients receiving follow-up with the median time as 16.1(7.5,34.6)months. The questionnaire response rate for low anterior resection syndrome (LARS) score was 48.3%(14/29). Of the patients who underwent redo coloanal anastomosis and closure of stoma successfully, there were 9 cases with mild-to-moderate LARS.Conclusion:Redo rectal resection and coloanal anastomosis is safe and feasible for patients undergoing local recurr-ence of tumors and failure of colorectal or coloanal anastomosis after rectal resection, which can successfully restore intestinal continuity in patients and avoid permanent enterostomy.

OBJECTIVE: To evaluate the effectiveness of limited internal fixation combined with a hinged external fixator in the treatment of peri-elbow bone infection. METHODS: The clinical data of 19 patients with peri-elbow bone infection treated with limited internal fixation combined with a hinged external fixator between May 2018 and May 2021 were retrospectively analyzed. There were 15 males and 4 females with an average age of 44.6 years (range, 28-61 years). There were 13 cases of distal humerus fractures and 6 cases of proximal ulna fractures. All the 19 cases were infected after internal fixation of fracture, and 2 cases were complicated with radial nerve injury. According to Cierny-Mader anatomical classification, 11 cases were type Ⅱ, 6 cases were type Ⅲ, and 2 cases were type Ⅳ. The duration of bone infection was 1-3 years. After primary debridement, the bone defect was (3.04±0.28) cm, and the antibiotic bone cement was implanted into the defect area, and the external fixator was installed; 3 cases were repaired with latissimus dorsi myocutaneous flap, and 2 cases were repaired with lateral brachial fascial flap. Bone defects repair and reconstruction were performed after 6-8 weeks of infection control. The wound healing was observed, and white blood cell (WBC), erythrocyte sedimentation rate (ESR), and C-reaction protein (CRP) were reexamined regularly after operation to evaluate the infection control. X-ray films of the affected limb were taken regularly after operation to observe the bone healing in the defect area. At last follow-up, the flexion and extension range of motion and the total range of motion of the elbow joint were observed and recorded, and compared with those before operation, and the function of the elbow joint was evaluated by Mayo score. RESULTS: All patients were followed up 12-34 months (mean, 26.2 months). The wounds healed in 5 cases after skin flap repair. Two cases of recurrent infection were effectively controlled by debridement again and replacement of antibiotic bone cement. The infection control rate was 89.47% (17/19) in the first stage. Two patients with radial nerve injury had poor muscle strength of the affected limb, and the muscle strength of the affected limb recovered from grade Ⅲ to about grade Ⅳ after rehabilitation exercise. During the follow-up period, there was no complication such as incision ulceration, exudation, bone nonunion, infection recurrence, or infection in the bone harvesting area. Bone healing time ranged from 16 to 37 weeks, with an average of 24.2 weeks. WBC, ESR, CRP, PCT, and elbow flexion, extension, and total range of motions significantly improved at last follow-up ( P<0.05). According to Mayo elbow scoring system, the results were excellent in 14 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 89.47%. CONCLUSION Limited internal fixation combined with a hinged external fixator in the treatment of the peri-elbow bone infection can effectively control infection and restore the function of the elbow joint.

Objective:To investigate the safety and efficacy of total pelvic exenteration (TPE) for treating late complications of radiation-induced pelvic injury.Methods:This was a descriptive case series study. The inclusion criteria were as follows: (1) confirmed radiation-induced pelvic injury after radiotherapy for pelvic malignancies; (2) late complications of radiation-induced pelvic injury, such as bleeding, perforation, fistula, and obstruction, involving multiple pelvic organs; (3) TPE recommended by a multidisciplinary team; (4) patient in good preoperative condition and considered fit enough to tolerate TPE; and (5) patient extremely willing to undergo the procedure and accept the associated risks. The exclusion criteria were as follows: (1) preoperative or intraoperative diagnosis of tumor recurrence or metastasis; (2) had only undergone diversion or bypass surgery after laparoscopic exploration; and (3) incomplete medical records. Clinical and follow-up data of patients who had undergone TPE for late complications of radiation-induced pelvic injury between March 2020 and September 2022 at the Sixth Affiliated Hospital of Sun Yat-sen University were analyzed. Perioperative recovery, postoperative complications, perioperative deaths, and quality of life 1 year postoperatively were recorded.Results:The study cohort comprised 14 women, nine of whom had recto-vagino-vesical fistulas, two vesicovaginal fistulas, one ileo-vesical fistula and rectal necrosis, one ileo-vesical and rectovaginal fistulas, and one rectal ulcer and bilateral ureteral stenosis. The mean duration of surgery was 592.1±167.6 minutes and the median blood loss 550 (100–6000) mL. Ten patients underwent intestinal reconstruction, and four the Hartmann procedure. Ten patients underwent urinary reconstruction using Bricker's procedure and 7 underwent pelvic floor reconstruction. The mean postoperative hospital stay was 23.6±14.9 days. Seven patients (7/14) had serious postoperative complications (Clavien-Dindo IIIa to IVb), including surgical site infections in eight, abdominopelvic abscesses in five, pulmonary infections in five, intestinal obstruction in four, and urinary leakage in two. Empty pelvis syndrome (EPS) was diagnosed in five patients, none of whom had undergone pelvic floor reconstruction. Five of the seven patients who had not undergone pelvic floor reconstruction developed EPS, compared with none of those who had undergone pelvic floor reconstruction. One patient with EPS underwent reoperation because of a pelvic abscess, pelvic hemorrhage, and intestinal obstruction. There were no perioperative deaths. During 18.9±10.1 months of follow-up, three patients died, two of renal failure, which was a preoperative comorbidity, and one of COVID-19. The remaining patients had gradual and significant relief of symptoms during follow-up. QLQ-C30 assessment of postoperative quality of life showed gradual improvement in all functional domains and general health at 1, 3, and 6 months postoperatively (all P<0.05). Conclusions:TPE is a feasible procedure for treating late complications of radiation-induced pelvic injury combined with complex pelvic fistulas. TPE is effective in alleviating symptoms and improving quality of life. However, the indications for this procedure should be strictly controlled and the surgery carried out only by experienced surgeons.

Objective:To explore the status of depression symptoms and related factors of depressive symptoms in middle-aged and elderly disabled people in China and provide references on the preventive cares of depression.Methods:Research data were obtained from the 2018 follow-up data of China Health and Retirement Longitudinal Study(CHARLS).Disabled people were selected as the research object. The scores of center for epidemiological studies depression scale(CES-D) were used to evaluate depressive symptoms. Fourteen variables derived from the 3 dimensions of demographic characteristics, health status, and health related behaviors were utilized in this study.SAS 9.4 were used for descriptive analysis, univariate analysis and Logistic regression analysis.Results:A total of 1 708 middle-aged and elderly disabled people were included, among whom 932(54.5%)were diagnosed with depressive symptoms, and the score of CES-D was (11.45±7.19).Self-rated poor health, self-rated poor memory, life dissatisfaction, physical pain were the risk factors of depressive symptoms ( OR=1.87, 4.22, 1.83, 5.30, 1.75). Male, educational level (middle-high school, high school or above), sleeping duration (6-9 h) were the protective factors of depressive symptoms( OR=0.74, 0.72, 0.10, 0.56). Conclusion:Middle-aged and elderly disabled people in China have a high detection rate of depressive symptoms. Female, lower education background, inadequate amount of sleep, self-rated unsatisfactory healthy, self-rated poor memory, dissatisfaction towards life and suffering from physical pain may be more likely to have depressive symptoms in middle-aged and elderly people with disabilities.

Objective:To preliminarily evaluate the feasibility and safety of laparoscopic Parks procedure for chronic radiation proctopathy (CRP).Methods:A descriptive cohort study was carried out. The clinical and follow-up data of 19 patients who received laparoscopic Parks procedure due to CRP in the Sixth Affiliated Hospital of Sun Yat-sen University from July 2013 to March 2019 were retrospectively analyzed. Inclusion criteria: (1) serious late complications occurred after pelvic radiotherapy, e.g.serious intractable hematochezia (hemoglobin <70 g/L), intractable anal pain (numerical rating scale >7), rectostenosis, perforation, and fistula. (2) imaging examinations including colonoscopy, pelvic MRI and/or chest, abdomen and pelvic CT were performed before surgery to confirm the lesions. Exclusion criteria: (1) preoperative or intraoperative diagnosis of tumor recurrence; (2) only ostomy was performed after laparoscopic exploration; (3) after neoadjuvant radiotherapy for rectal cancer; (4) incomplete medical records. Surgical procedures: (1) Laparoscopic exploration: tumor recurrence was excluded, and the range of radioactive damage in the intestine was determined. Marks were made on the proximal sigmoid colon without grossly obvious edema, thickening or radioactive injuries. (2) Abdominal operation: the right mesentery of sigmoid colon and rectum was opened, inferior mesenteric vein and inferior mesenteric artery were divided and the Toldt gap was expanded inwards and cephalad. The outside of left hemicolon was freed, the gastrocolic ligament was opened, the splenic flexure was fully mobilized, and the rectum was separated from the rear, side and front to the lowest point. Then perineal operation was performed. (3) Perineal operation: the whole layer of rectum wall was cut thoroughly at 1cm below the lesion's lower margin, the space around the rectum was fully separated, the rectum and sigmoid colon was pulled out through the anus and cut off at the site of the grossly normal intestine, the diseased bowel was removed and a coloanal anastomosis was made. (4) A protective stoma was performed. Conditions of operation, complication and symptom relief were summarized. A descriptive statistic method was used to analyze the results.Results:All the 19 patients were female with a median age of 53 (interquartiles, 50, 56) years old, of whom 18 patients had primary cervical cancer. Surgical indications: 9 cases were rectovaginal fistula; 9 cases were intractable anal pain, among whom 7 were complicated with deep rectal ulcer; and 1 case was intractable hematochezia with deep rectal ulcer. Eighteen cases completed laparoscopic Parks procedure, while 1 case was converted to laparotomy. The median operative time was 215 (131, 270) minutes, the median bleeding volume was 50 (50, 100) ml, and the median hospital stay was 12 (11, 20) days. There was no perioperative death. Ten cases had postoperative complications, including 3 cases of serious complications (CD grade IIIb and above) within 30 days after operation, of whom one case developed pelvic infection caused by rectovaginal, rectovesical and rectourethral fistula and acute renal failure (IVa); 2 cases developed orifice prolapse and parastomal hernia (IIIb). Seven cases had anastomosis-related complications, including 4 cases of grade A anastomotic leakage and 3 cases of anastomotic stenosis. Symptoms of CRP in the whole group were significantly relieved or disappeared after one year of the operation. Five cases achieved stoma closure.Conclusions:Laparoscopic Parks procedure for chronic radiation proctopathy is safe and feasible, and can effectively improve symptoms. However, the incidence of anastomotic complications is high, so the surgical indications should be strictly controlled.
