RESUMEN
Objective: To investigate the prognostic value of enteroscopic grading for the prognostic assessment of patients with malignant hematological diseases who developed intestinal acute graft-versus-host disease (IT-aGVHD) after unrelated cord blood transplantation (UCBT) . Methods: Fifty patients with IT-aGVHD who developed hormone resistance after UCBT from June 2016 to June 2023 at Anhui Provincial Hospital were collected to compare the effective and survival rates of IT-aGVHD treatment in the group with milder enteroscopic mucosal injury (27 cases, enteroscopic grading of â and â ¡) and the group with more severe injury (23 cases, enteroscopic grading of â ¢ and â £) and to retrospectively analyze the factors affecting patients' prognosis. Results: Patients in the mild and severe groups had an effective rate of 92.6% and 47.8% at 28 days after colonoscopy (P<0.001), 81.5% and 39.1% at 56 days after colonoscopy (P=0.002), with optimal effective rate of 92.6% and 65.2% (P=0.040), respectively, and the differences were statistically significant. The multifactorial analysis found that enteroscopic grading was an independent risk factor affecting the effective rate of IT-aGVHD treatment. The overall survival rate at 2 years after colonoscopy was 70.4% (95% CI 52.0% -88.8% ) and 34.8% (95% CI 14.8% -54.8% ) for patients in the mild and severe groups, respectively, and the difference was statistically significant (P=0.003). Multifactorial analysis revealed that enteroscopic grading, cytomegalovirus infection status, second-line treatment regimen, and patients' age were independent risk factors for survival. Conclusion: The treatment efficacy and prognosis of patients in the group with less severe enteroscopic injury (grades â and â ¡) were better than those in the group with more severe injury (grades â ¢ and â £) .

Objective: To understand the prevalence of major chronic diseases of diabetes, cardiovascular disease and malignant tumor in people living with HIV in Taizhou. Methods: The data were collected from China Information System for Disease Control and Prevention and Taizhou Chronic Disease Information Management System. A total of 5 126 people living HIV under follow-up in Taizhou from 1998 to 2022 were included in the analysis. Software SAS 9.4 was used for χ2 test, trend analysis and logistic regression analysis. Results: In the 5 126 people living with HIV, the reported prevalence rates of diabetes,cardiovascular disease and malignant tumor were 10.28% (527/5 126),3.98% (204/5 126) and 6.01% (308/5 126), respectively. 37.00% (195/527) and 48.58% (256/527), 40.20% (82/204) and 48.53% (99/204), 37.66% (116/308) and 48.38% (149/308) were diagnosed as diabetes, cardiovascular disease and malignant tumor before and after confirmation of HIV infection. From 2013 to 2022, the proportion of HIV infected people diagnosed with diabetes, cardiovascular disease and malignant tumor after confirmation increased (trend χ2=79.98,P<0.001; trend χ2=17.44,P<0.001; trend χ2=32.06,P<0.001). Based on the analysis on the factors for complicated chronic diseases in people living with HIV, it was found that women under 60 years old (aOR=0.66, 95%CI: 0.50-0.86) and those with access to antiviral treatment for >5 years before 2016 (aOR=0.54,95%CI:0.37-0.78) were less likely to develop complicated chronic diseases, and those under 60 years old with initial CD4+T lymphocytes counts <200 cells/µl (aOR=1.32, 95%CI: 1.02-1.70), those aged 40-49 and 50-59 years (aOR=2.88, 95%CI:2.20-3.79; aOR=5.43, 95%CI: 4.10-7.21) as well as those without a record of treatment medication use after 2016 (aOR=1.95,95%CI:1.20-3.16) were more likely to develop complicated chronic diseases. The probability of developing complicated chronic diseases might increase with age in people living with HIV. Conclusions: From 1998 to 2022, there was a certain proportion of complicated chronic diseases among HIV infected individuals in Taizhou, and the proportion of diagnosed cases increased after HIV infection was confirmed. It is necessary to conduct early chronic disease screening, behavior intervention and standardized management in people living with HIV.

Objective: To assess the compliance with a lung protective ventilation strategy and to evaluate the relationship with prognosis in patients with acute respiratory distress syndrome (ARDS). Methods: In the prospective multicenter cohort study (CHARDS), patients with ARDS undergoing invasive mechanical ventilation were enrolled to collect essential information, mechanical ventilation data, and prognostic data. Compliance was operationally defined as tidal volume ≤7 ml/kg predicted body weight (PBW) or plateau pressure ≤30 cmH2O or driving pressure≤15 cmH2O. Tidal volume data collected 7 days prior to ventilation after ARDS diagnosis were categorized into four groups: standard group (Group A, 100% compliance), non-standard group (Group B, 50%-99% compliance, Group C,1%-49% compliance,and Group D,totally non-compliant). Plateau pressure and drive pressure measurements were recorded on the first day. Stepwise regression, specifically Logistics regression, was used to identify the factors influencing ICU survival. Results: A total of 449 ARDS patients with invasive mechanical ventilation were included; the proportion of mild, moderate, and severe patients was 71 (15.8%), 198 (44.1%) and 180 (40.1%), respectively. During the first 7 days, a total of 2880 tidal volume measurements were recorded with an average tidal volume of (6.89±1.93) ml/kg PBW. Of these measurements, 53.2% were found to be≤7 ml/kg PBW. The rates of compliance with lung protective mechanical ventilation were 29.8% (134/449), 24.5% (110/449), 23.6% (106/449), and 22% (99/449) in groups A, B, C, and D, respectively. In the standard group, the tidal volume for mild ARDS patients was 18.3%(13/71), while it was 81.7%(58/71)in the non-standard group. Similarly, in patients with moderate ARDS, the tidal volume was 25.8% (51/198) in the standard group, while it was 74.2% (147/198) in the non-standard group. Finally, in patients with severe ARDS, the tidal volume was 38.9% (70/180) in the standard group, while it was 61.1% (110/180) in the non-standard group. Notably, the compliance rate was higher in patients with moderate and severe ARDS in group A compared to patients with mild and moderate ARDS (18.3% vs. 25.8% vs. 38.9%, χ2=13.124, P=0.001). Plateau pressure was recorded in 221 patients, 95.9% (212/221) patients with plateau pressure≤30 cmH2O, and driving pressure was recorded in 207 patients, 77.8% (161/207) patients with a driving pressure ≤15 cmH2O.During the first 7 days, the mortality rate in the intensive care unit (ICU) was lower in the tidal volume standard group compared to the non-standard group (34.6% vs. 51.3%, χ2=10.464, P=0.001). In addition, the in-hospital mortality rate was lower in the standard group compared to the non-standard group (39.8% vs. 57%, χ2=11.016, P=0.001).The results of the subgroup analysis showed that the mortality rates of moderate and severe ARDS patients in the standard group were significantly lower than those in the non-standard group, both in the ICU and in the hospital (all P<0.05). However, there was no statistically significant difference in mortality among mild ARDS patients (all P>0.05). Conclusions: There was high compliance with recommended lung protective mechanical ventilation strategies in ARDS patients, with slightly lower compliance in patients with mild ARDS, and high compliance rates for plateau and drive pressures. The tidal volume full compliance group had a lower mortality than the non-compliance group, and showed a similar trend in the moderate-to-severe ARDS subgroup, but there was no significant correlation between compliance and prognosis in patients with mild ARDS subgroup.

Doxorubicin is an anthracycline antitumor antibiotic with dose-dependent and cumulative cardiotoxicity. However, the necessity for serial cardiac evaluation is unknown in dogs without risk factors for dilated cardiomyopathy (DCM). This study aimed to investigate serial changes in echocardiographic and electrocardiographic measures in small- and medium-sized dogs after four doxorubicin doses. We included 17 dogs, weighting < 20â¯kg, with multicentric lymphoma. All dogs received doxorubicin over 30â¯min every 4 weeks as part of a multi-drug chemotherapy protocol. The average doxorubicin dose was 3.8 times per dog. Clinical cardiotoxicity was not observed during the monitoring period. The incidence of developing arrhythmia was not significantly associated with the number of doxorubicin doses received (P = 0.600). The development of valvular regurgitations and mitral regurgitation in these dogs was not significantly associated with the number of doxorubicin doses (P = 0.363 and P = 0.779, respectively). The other echocardiographic results were not significantly different between each evaluation. In conclusion, our results showed no significant cardiotoxicity under echocardiogram and electrocardiogram in small- and medium-sized dogs without risk factors for DCM after four doses of doxorubicin in a 30-minute infusion method.

BACKGROUND: Oral submucous fibrosis (OSF) is a precancerous lesion characterized by fibrous tissue deposition, the incidence of which correlates positively with the frequency of betel nut chewing. Prolonged betel nut chewing can damage the integrity of the oral mucosal epithelium, leading to chronic inflammation and local immunological derangement. However, currently, the underlying cellular events driving fibrogenesis and dysfunction are incompletely understood, such that OSF has few treatment options with limited therapeutic effectiveness. Dental pulp stem cells (DPSCs) have been recognized for their anti-inflammatory and anti-fibrosis capabilities, making them promising candidates to treat a range of immune, inflammatory, and fibrotic diseases. However, the application of DPSCs in OSF is inconclusive. Therefore, this study aimed to explore the pathogenic mechanism of OSF and, based on this, to explore new treatment options. METHODS: A human cell atlas of oral mucosal tissues was compiled using single-cell RNA sequencing to delve into the underlying mechanisms. Epithelial cells were reclustered to observe the heterogeneity of OSF epithelial cells and their communication with immune cells. The results were validated in vitro, in clinicopathological sections, and in animal models. In vivo, the therapeutic effect and mechanism of DPSCs were characterized by histological staining, immunohistochemical staining, scanning electron microscopy, and atomic force microscopy. RESULTS: A unique epithelial cell population, Epi1.2, with proinflammatory and profibrotic functions, was predominantly found in OSF. Epi1.2 cells also induced the fibrotic process in fibroblasts by interacting with T cells through receptor-ligand crosstalk between macrophage migration inhibitory factor (MIF)-CD74 and C-X-C motif chemokine receptor 4 (CXCR4). Furthermore, we developed OSF animal models and simulated the clinical local injection process in the rat buccal mucosa using DPSCs to assess their therapeutic impact and mechanism. In the OSF rat model, DPSCs demonstrated superior therapeutic effects compared with the positive control (glucocorticoids), including reducing collagen deposition and promoting blood vessel regeneration. DPSCs mediated immune homeostasis primarily by regulating the numbers of KRT19 + MIF + epithelial cells and via epithelial-stromal crosstalk. CONCLUSIONS: Given the current ambiguity surrounding the cause of OSF and the limited treatment options available, our study reveals that epithelial cells and their crosstalk with T cells play an important role in the mechanism of OSF and suggests the therapeutic promise of DPSCs.

Objectives: To assess the prognostic impact of the neoadjuvant rectal (NAR) score following neoadjuvant short-course radiotherapy and consolidation chemotherapy in locally advanced rectal cancer (LARC), as well as its value in guiding decisions for adjuvant chemotherapy. Methods: Between August 2015 and August 2018, patients were eligible from the STELLAR phase III trial (NCT02533271) who received short-course radiotherapy plus consolidation chemotherapy and for whom the NAR score could be calculated. Based on the NAR score, patients were categorized into low (ï¼8), intermediate (8-16), and high (ï¼16) groups. The Kaplan-Meier method, log rank tests, and multivariate Cox proportional hazard regression models were used to evaluate the impact of the NAR score on disease-free survival (DFS). Results: Out of the 232 patients, 24.1%, 48.7%, and 27.2% had low (56 cases), intermediate (113 cases), and high NAR scores (63 cases), respectively. The median follow-up period was 37 months, with 3-year DFS rates of 87.3%, 68.3%, and 53.4% (Pï¼0.001) for the low, intermediate, and high NAR score groups. Multivariate analysis demonstrated that the NAR score (intermediate NAR score: HR, 3.10, 95% CI, 1.30-7.37, P=0.011; high NAR scores: HR=5.44, 95% CI, 2.26-13.09, Pï¼0.001), resection status (HR, 3.00, 95% CI, 1.64-5.52, Pï¼0.001), and adjuvant chemotherapy (HR, 3.25, 95% CI, 2.01-5.27, Pï¼0.001) were independent prognostic factors for DFS. In patients with R0 resection, the 3-year DFS rates were 97.8% and 78.0% for those with low and intermediate NAR scores who received adjuvant chemotherapy, significantly higher than the 43.2% and 50.6% for those who did not (Pï¼0.001, P=0.002). There was no significant difference in the 3-year DFS rate (54.2% vs 53.3%, P=0.214) among high NAR score patients, regardless of adjuvant chemotherapy. Conclusions: The NAR score is a robust prognostic indicator in LARC following neoadjuvant short-course radiotherapy and consolidation chemotherapy, with potential implications for subsequent decisions regarding adjuvant chemotherapy. These findings warrant further validation in studies with larger sample sizes.

Anorexia, depression, and vomiting are the common adverse effects of chemotherapy in humans and animals. Mirtazapine is primarily used as an appetite stimulant and antiemetic in dogs and cats. Therefore, we evaluated the efficacy of mirtazapine in reducing the gastrointestinal adverse effects in cats receiving doxorubicin chemotherapy. This single-masked, placebo-controlled crossover study enrolled 11 cats with malignant mammary gland tumors. The cats were randomly assigned to receive either mirtazapine (1.88â¯mg/cat) or placebo every 48â¯h for 2 weeks from the first initiation of doxorubicin chemotherapy. Each cat was then crossed over to the alternate group on the subsequent chemotherapy with a 1-week wash-out period. The owners were asked to record appetite score, activity score, episodes of vomiting and diarrhea for 2 weeks after each doxorubicin administration. Cats treated with mirtazapine showed signiï¬cantly increased bodyweight compared with those on placebo (P = 0.010). The appetite and activity scores during mirtazapine treatment was significantly higher than those during placebo treatment (P = 0.005 and 0.018, respectively). Furthermore, the prevalence of episodes of vomiting during mirtazapine treatment was significantly lower than that during placebo treatment (P = 0.026). Our results demonstrate that mirtazapine can significantly increase bodyweight, appetite, and activity and reduce vomiting in cats after doxorubicin chemotherapy.

Objective: To compare the prevalence of frailty and related factors in middle-aged and elderly people aged ≥45 years in island and mountainous areas of Taizhou, Zhejiang Province. Methods: Based on cross-sectional design, stratified cluster sampling and quota sampling methods were adopted. One administrative district was randomly selected from each of six coastal and three inland administrative districts in Taizhou during July to August, representing two different geographical terrains. In the island area (Jiaojiang District), all residents aged ≥45 years were included by cluster sampling. In the mountainous area (Xianju County), participants were selected through quota sampling, with same gender and age distributions. Data about their demographic characteristics, lifestyle and health-related factors were collected through questionnaire surveys and laboratory examinations. The prevalence of frailty was assessed using the Fried frailty phenotype scale. Hierarchical analysis and multivariate logistic regression analysis were used to compare the influencing factors of frailty. Results: A total of 1 011 local residents were studied, in whom island and mountainous residents accounted for 48.1% (486/1 011) and 51.9% (525/1 011) respectively; men and women accounted for 45.9% (464/1 011) and 54.1% (547/1 011) respectively. Middle-aged (45-49 years), younger elderly (60-74 years), and older elderly (≥75 years) residents accounted for 38.6% (390/1 011), 44.6% (451/1 011), and 16.8% (170/1 011) respectively. The overall prevalence rate of frailty was 3.6% (36/1 011), the prevalence rate was 3.7% (17/464) in men and 3.5% (19/547) in women. The prevalence rates in age groups 45-59,60-74 years and ≥75 years were 0.3% (1/390), 2.2% (10/451), and 14.7% (25/170), respectively. The prevalence rates of frailty and pre-frailty in island area were 6.0% (29/486) and 39.1% (190/486), respectively, which was higher than those in mountainous area (1.3%, 7/525) and (30.9%, 162/525). After adjusting for potential confounding factors, the risk for frailty in island residents was significantly higher than that in mountainous residents (aOR=1.55,95%CI: 1.07-2.25,P=0.019). In island area, older age (60-74 years:aOR=2.52,95%CI: 1.56-4.13; ≥75 years:aOR=11.65,95%CI:5.38-26.70), being women (aOR=1.94,95%CI: 1.20-3.17), suffering from depression (aOR=1.09,95%CI:1.02-1.17) were associated with frailty symptoms. In mountainous area, older age was also associated with an increased risk of frailty symptoms, but the OR value was lower than those in island area (60-74 years: aOR=1.74,95%CI:1.04-2.94;≥75 years: aOR=4.78,95%CI:2.45-9.50). Polydrug use (aOR=2.08,95%CI: 1.14-3.80) and suffering from depression (aOR=1.10,95%CI: 1.02-1.18) had significant positive association with frailty symptoms. Higher education level had significant negative association with frailty symptoms (junior high school: aOR=0.40,95%CI: 0.21-0.75; senior high school and technical secondary school: aOR=0.29,95%CI: 0.15-0.53; college or above:aOR=0.22,95%CI: 0.11-0.42). Conclusions: The prevalence of frailty in middle-aged and elderly community residents was significantly higher in island area than in mountainous area in Taizhou. The frailty-related factors varied with area. The elderly people (≥75 years) and women in island area had higher risk for frailty. Older age and suffering from depression were the independent risk factors for frailty. It is necessary to pay attention to the health risk factors and special environment in island area, and take comprehensive intervention measures to delay the process of debilitation and improve the quality of life of middle-aged and elderly people.

BACKGROUND: The surgical treatment of recurrent nasopharyngeal carcinoma (rNPC) involving the internal carotid artery (ICA) is challenging, as the massive bleeding caused by intraoperative rupture of the ICA is life-threatening. We reported that ICA embolization is an effective pretreatment to avoid fatal bleeding, but some patients cannot tolerate the procedure. We used endovascular vascular protection (ICA stents), vascular sacrifice (bypass grafting) and extravascular vascular protection (transcervical external stent placement) of the ICA to provide alternative options for these patients. METHODOLOGYy: This study enrolled patients with rNPC adjacent to or invading the ICA who were unsuitable for ICA embolization from January 2015 to June 2020. ICA pretreatment combined with endoscopic nasopharyngectomy (ENPG) was performed for the 30 patients. We report the survival outcome and incidence of complications after ICA pretreatment. RESULTS: ICA pretreatment was performed for the 30 enrolled patients, among whom 8 underwent endoscopic-assisted transcervical protection of the parapharyngeal ICA combined with ENPG, 6 underwent bypass grafting, and 16 underwent ICA stent implantation followed by ENPG. After pretreatment, at a median follow-up of 43 months (range, 2-80 months), the 3-year locoregional overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS) were 62.9%, 61.3%, 70.2%, and 71.4%, respectively. CONCLUSIONS: ICA pretreatment combined with salvage ENPG enables the feasible and effective resection of rNPC lesions involving the ICA in patients who cannot tolerate ICA embolization. Therefore, this treatment may be an effective method for improving outcomes. Multidisciplinary therapy is needed to reduce operation-related complications.
RESUMEN
Objective: To improve understanding and treatment of adult Hirschsprung's disease (HD) and Hirschsprung's disease allied disorders (HAD) by investigating the clinicopatho- logical features, diagnostic and treatment methods, and prognosis. Methods: This was a retrospective observational study. The study cohort comprised patients aged 18-65 years admitted to the Sixth Hospital of Sun Yat-sen University between January 2007 and December 2022 who were diagnosed with adult HD or HAD by postoperative pathological examination. Those with severe cardiovascular disease, diabetes mellitus, or cirrhosis of the liver were excluded, leaving 47 patients in the study cohort. Emergency open surgery was performed on patients with life-threatening manifestations, whereas those whose condition was stable received conservative treatment to stabilize them, following which they underwent a standard surgical procedure. Surgical procedures performed included the Duhamel procedure, Soave procedure, subtotal colonic resection, total colonic resection, and creation of a palliative stoma. Variables studied included clinicopathological characteristics, treatment modalities, postoperative complications, and long-term anal function. Complications were evaluated in accordance with the Clavien-Dindo criteria, and long-term anal function according to the 2005 Krickenbeck International Classification Criteria. Results: Of the 47 patients, 33 were men and 14 women, with a median age of 29 (18-51) years. HD was diagnosed in 41 (87.2%) patients and HAD in six (12.8%). The commonest initial symptom was dyspareunia (70.2%,33/47), followed by abdominal distension (57.4%, 27/47) and abdominal pain (44.7%,21/47). The detection rates of HD/HAD by barium enema + defecography, anorectal manometry, and preoperative rectal biopsy were 86.8% (33/38), 16/19, and 7/7, respectively. Three (6.4%) patients had discrepant preoperative clinical and postoperative pathological diagnoses. None of the three misdiagnosed patients had undergone preoperative rectal biopsy. Of the 47 study patients, three chose non-surgical treatment and 44 surgical treatment. All surgeries were successfully completed. Postoperative complications occurred in 19 patients (43.2%), including one death case who had undergone emergency surgery. The median duration of follow-up after surgery was 65 (12-180) months. Three patients in the surgical treatment group were lost to follow-up. Of the remaining 41 patients, 36, three, and two had excellent, good, and poor long-term anal function, respectively. The differences in outcomes between the surgical and non-surgical treatment groups (no patients, one, and two with excellent, good, and poor long-term anal function, respectively) (Z=-3.883, P=0.001) were statistically significant. Of the 44 patients who underwent surgical treatment, 41 underwent standard surgeries and three emergency surgeries because their conditions were life-threatening. The difference in complication rate between standard surgery and emergency surgery groups (39.0% [16/41] vs. 3/3, χ2=2.115, P=0.146) was not statistically significant. However, the rate of postoperative Grade III-V complications was lower in the standard surgery group (4.9% [2/41] vs. 2/3, Z=-2.668, P=0.008). Long-term anal function was significantly better in the standard surgery than emergency surgery group (94.7% [36/38] vs. 0/3, Z=-4.935, P=0.001). The 41 standard surgeries included 11 Duhamel's procedures, six Soave's procedures, 19 subtotal colonic resections, three total colonic resections, and two palliative colostomies. The incidence of postoperative complications was significantly superior in the Duhanmels procedures and palliative colostomies group(1/11 and 0/2, P=0.041). Of the 41 patients who underwent standard surgery, 23 underwent open surgery and 18 minimally invasive laparoscopic surgery. The incidence of postoperative Grade III-V complications and long-term anal function were significantly superior in the laparoscopic group than in the open group (all P<0.05). Conclusion: It is easy to misdiagnose adult HD and HAD, surgical treatment is safe and feasible, and its long-term efficacy is good.

Objective: To investigate the association of cardiovascular diseases (CVD) with triglyceride glucose index (TyG) and TyG-related indicators in Uyghur populations of The Xinjiang Production and Construction Corps. Methods: Based on the cohort of the Uygur population of The Xinjiang Production and Construction Corps, 11 833 study subjects were included. The Kaplan-Meier method was used to estimate the cumulative incidence of CVD in each quartile of TyG and TyG-related indicators. Cox proportional hazards regression model was used to evaluate the relationship between TyG and CVD, TyG-related indicators and CVD. Framingham CVD risk score model (Framingham model) was used to evaluate whether the addition of TyG and TyG-related indicators could improve the predictive ability of the model. The potential mediating role of the TyG in the association between obesity and CVD was examined through mediation effect analysis. Results: The average age of the subjects was (37.00±13.67) years-old, and 51.0% were male. The median follow-up time was 5.67 years, with 1 288 CVD events. The cumulative incidence of CVD increased with the increase of TyG and TyG-related indicators quartiles, and compared with the Q1 group, the risk of CVD in the Q4 group of TyG, TyG-BMI, and TyG-WHtR increased by 20% (HR=1.20, 95%CI: 1.01-1.42), 77% (HR=1.77, 95%CI: 1.46-2.16) and 68% (HR=1.68, 95%CI: 1.36-2.09), respectively. After adding TyG, TyG-BMI, and TyG-WHtR to the Framingham model, respectively, the model's area under the curve, net reclassification improvement, and integrated discrimination improvement were improved. In the association between BMI, WHtR, and CVD, the proportion of mediating effects mediated by the TyG index was 10.55% and 11.50%. Conclusions: Elevated levels of TyG and TyG-related indicators were strongly associated with the risk of CVD in the Uyghur population of The Xinjiang Production and Construction Corps, with TyG-BMI being the most closely correlated with CVD. Early monitoring of TyG-BMI helps identify high-risk groups of CVD.

Objective: To investigate the curative effects of bi-pedicled deep inferior epigastric perforator (DIEP) flap in repairing large soft tissue defects in the lower limbs. Methods: A retrospective observational study was conducted. From February 2016 to June 2020, 16 patients with large soft tissue defects in the lower limbs caused by trauma or after tumor/scar resection were admitted to the Department of Hand Surgery of the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, including 9 males and 7 females, aged 25-58 years, with the area of soft tissue defects ranging from 14.0 cm×8.0 cm to 32.0 cm×18.0 cm. Using the abdomen as the donor site, the conjoined abdominal wall flap, i.e., the bi-pedicled DIEP flap (with an area ranging from 15.0 cm×9.0 cm to 32.0 cm×20.0 cm) carrying two sets of the trunk of the deep inferior epigastric artery was designed and resected to repair the wound. The donor site wound was sutured directly. The flap survival and wound healing in the donor and recipient areas were observed after operation. The curative effect was evaluated during the follow-up. At the last follow-up, the American Knee Society score and lower extremity functional scale were used to assess the functions of knee joint and lower limb, respectively. Results: The flaps of 15 patients survived after operation; the flap of one patient had partial infection at the edge after operation but healed after debridement and dressing change. The wounds in the donor and recipient areas of 16 patients all healed well. Follow-up of 16-28 months showed that the recipient area had a good shape and pliable texture, and there was no obvious swollen appearance, hyperpigmentation, or abnormal hair growth; the donor site had linear scar only, with no complications such as abdominal hernia or hyperplastic scar; the functions of knee joint and lower limb were well reconstructed, with no recurrence of tumor. At the last follow-up, among the 4 patients with knee joint injury, 3 cases were excellent and 1 case was good in the evaluation of knee joint function; among the 12 patients with lower limb injury, 9 cases were excellent and 3 cases were good in the evaluation of lower limb function. Conclusions: The donor site of bi-pedicled DIEP flap is concealed with abundant tissue and large area for resection, with which can be used to repair large soft tissue defects in the lower limbs, achieving good short-term results of appearance and function restoration.

Objective: To understand the incidence and causes of HIV/AIDS death patients in Taizhou from 1998 to 2022. Methods: The data were collected from the AIDS Integrated Prevention and Control Information System of China Information System for Diseases Control and Prevention and Taizhou Chronic Disease Information Management System. By the end of 2022, a total of 5 126 HIV/AIDS patients living in Taizhou for a long time were included, SAS 9.4 was used for Kruskal-Wallis test, χ2 test and trend analysis. Results: From 1998 to 2022, a total of 796 HIV/AIDS patients died, with a fatality rate of 15.53% (796/5 126), in whom 52.26% (416/796) died within one year after confirmation. The proportion of HIV/AIDS patients who died within one year decreased (trend χ2=5.60, P<0.001). For the constituent of death causes, there were 140 (17.59%) deaths of AIDS, 237 (29.77%) deaths of malignant tumors, 99 (12.44%) deaths of cardiovascular disease, 58 (7.29%) deaths caused by injuries, 160 (20.10%) deaths due to other causes, and 102 (12.81%) deaths due to unknown causes. The constituent ratio of deaths of malignant tumor, cardiovascular disease and other causes increased over time (trend χ2=1.92, P=0.028; trend χ2=2.81, P=0.003; trend χ2=2.07, P=0.020). There were differences in the distribution of death causes in HIV/AIDS cases in terms of age, occupation, marital status, ethnic group, educational level and mode of transmission (all P<0.05). The average age of the death cases due to cardiovascular disease was higher than other death cases, the cases who died from AIDS had shorter survival time and the lower initial CD4+T cells after confirmation compared with all other death cases, and the time interval from confirmation to treatment in HIV/AIDS patients with unknown death causes was longer than those of all other death cases (all P<0.05). Conclusions: The constituent ratio of non-AIDS related deaths in HIV/AIDS patients in Taizhou was relatively high and showed an upward trend during 1998-2022. It is necessary to further strengthen the early screening, prevention and treatment of chronic non infectious diseases.

A 45-year-old female patient was found to have a nodule in the right lower lobe on physical examination. Chest CT showed the nodule was lobulated measuring 24 mm×23 mm, with obvious enhancement and adjacent pleural traction. As the PET-CT showed increased 18F-FDG uptake suggesting malignancy, the wedge resection of the right lower lobe was performed. Grossly, the mass was adjacent to the pleural area with indistinct boundary. On cut sections, the lesion was solid and tough, with a greyish-pink colour. Microscopically, the lesion had an ill-defined margin, and was composed of spindle and polygonoid histiocytes with rich eosinophilic cytoplasm similar to rhabdoid muscle cells. The cytoplasm of histiocytes was filled with diamond-shaped or club-shaped crystals. Immunohistochemistry (IHC) showed the histiocytes were positive for CD68, κ, λ, IgG, IgM and IgA. The patient had been followed up for 41 months and had shown neither recurrences nor new diseases. CSH is a rare non-neoplastic histiocytic proliferative disease. Pulmonary CSH should be differentiated from multiple diseases. Accurate pathological diagnosis depends on its morphology and immunophenotype. This disease is often related to potential lymphoproliferative or plasma cell disorder. After diagnosis, a systemic examination is required and long-term follow-up is recommended.

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage â ¢ and 4 of stage â £. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

Homeostasis is a dynamic balance process of self-regulating. Biological systems remain stable through adapting to changing external conditions to maintain normal life activities. Homeostatic medicine is the science of studying homeostasis of human molecules, cells, organs and the whole body. It is a comprehensive discipline based on maintaining homeostasis to keep human health and assist for diseases prevention and diagnoses. Homeostatic medicine focuses on the whole body and on the role of homeostasis in health and disease, which is expected to provide new ideas and strategies for maintaining health as well as diagnosing and treating diseases. Nitric oxide (NO) plays an important role in the control of multisystem homeostasis. Nitrate is an important substance in regulating NO homeostasis through the nitrate-nitrite-NO pathway. Sialin, nitrate transporter which is located in the cell membrane and cytoplasm, mediates multiple cellular biological functions. The nitrate-nitrite-NO pathway and sialin-mediated biological functions play an important role in the regulation of body homeostasis.

OBJECTIVE: In addition to significantly reducing breast cancer recurrence risk, radiotherapy also prolongs patients' lives. However, radiotherapy-related genes and biomarkers still remain poorly understood. The present study aimed to identify radiation-associated genes in breast cancer. MATERIALS AND METHODS: Breast cancer data were downloaded from Gene Expression Omnibus (GEO) and UCSC Xena database. The gene ontology (GO) enrichment and gene set enrichment analysis (GSEA) were performed for annotation and integrated discovery. Protein-protein interaction (PPI) network was constructed by STRING database and hub genes were identified. Then, immunohistochemistry and tissue expression of key genes was analyzed by using the Human Protein Atlas (HPA) and GEPIA database. Genes associated with prognosis were identified by performing univariate cox analysis. RESULTS: We identified 341 differentially expressed genes related to radiotherapy in breast cancer patients. PPI analysis revealed a total of 129 nodes and 516 interactions and identified five hub genes (EGFR, FOS, ESR1, JUN, and IL6). In addition, 11 SDEGs THBS1, SERPINA11, NFIL3, METTL7A, KCTD12, HSPA6, EGR1, DDIT4, CCDC3, C11orf96, and BCL2A1 candidate genes can be used as potential diagnostic markers. The calibration curve and ROC indicate good probability consistencies of 3-years and 5-year survival rates of patients between estimation and observation. CONCLUSIONS: Our findings provide novel insight into the functional characteristics of breast cancer through integrative analysis of GEO data and suggest potential biomarkers and therapeutic targets for breast cancer.
