Objective To explore the clinical features of invasive fungal infection in 27 children treated at nephrology department between 1999 and 2014.Methods Twenty-seven cases of invasive fungal infection at nephrology department were analyzed retrospectively.Results Candida urinary infection was found in 9 cases,pneumocystis carinii pneumonia were found in 8 cases,invasive pulmonary aspergillosis and urinary aspergillosis found in 4 cases and 1 case respectively,cryptococcus neoformans meningitis and pulmonary candidiasis found respectively in 2 cases,and pulmonary filamentous fungal disease was found in 1 case.These 27 cases showed different features of illness:10 primary nephrotic syndrome,7 secondary nephrotic syndrome,6 malformation of urinary development and 4 preterm birth ＜ 32 weeks gestational age with low birth weight.All of the cases had the history of taking antibiotics.Seventeen cases of them had used corticosteroid and cytotoxic drugs in a long-term.Sixteen cases had experienced invasive procedures.All children had fever in varying degrees,14 cases showed gasp,7 cases had progressive hypoxia and respiratory failure,and 5 cases developed into multiple organs failure.Chest computed tomographic (CT) imaging data showed diffuse ground-glass opacity with mosaic sign of pneumocystis carinii pneumonia(8 cases).The features of pulmonary aspergillosis included multiple nodules and cavity in bilateral lungs (4 cases).The radiologic findings showed patching lesions with indistinct edge and uncertained density of bilateral middle-lower lung fields with pulmonary candidiasis (2 cases).Full dose of antifungal drug was given to 23 cases of them,16 cases recovered completely,3 got better,4 cases died.Four cases gave up full dose antifungal therapy.Conclusions Long-term use of corticosteroid and cytotoxic drugs,use of broad-spectrum antibiotics,invasive therapies,such as indwelling centralvenous catheters,endotracheal intubation with mechanical ventilation,and preterm birth with low birth weight were risk factors in predicting invasive fungal infection.Chest CT findings were different among these cases.Even though not specific,the relatively differences were helpful to the differential diagnosis of these diseases.

Objective:To evaluate the treatment of infected nonunion after internal fixation of subtrochanteric fracture with a reconstruction stent of external fixation.Methods:A retrospective study was conducted to analyze the data of 5 male patients with infected nonunion after internal fixation of subtrochanteric fracture who had been treated and completely followed up at The Great Wall Orthopaedics and Hand Surgery Hospital from January 2017 to October 2022. The patients were (30.0±13.5) years old. Seinsheimer fracture types: ⅢA (1 case), ⅢB (1 case), Ⅳ (2 cases), and Ⅴ (1 case); original internal fixation: intramedullary system (4 cases) and plate fixation (1 case); the Cierny-Mader anatomical classification: type Ⅳ (diffuse type) for all. After complete debridement at stage one, 2 or 3 hydroxyapatite (HA) coated screws were placed at both fracture ends from the lateral side of the femur for unilateral reconstruction external fixation. Next, a hybrid external fixation scaffold was added with a 1/3 ring at the sagittal position and 1 or 2 HA screws in 4 cases while unilateral reconstruction external fixation was constructed at both sides by inserting 2 HA screws into both fracture ends from the anterior femur at the sagittal position in 1 case. Antibiotic bone cement was used to fill bone defects of (3.8±1.8) cm. At 6 to 8 weeks after debridement when infection did not recur, antibiotic bone cement was removed before autogenous iliac bone grafting was performed in 3 patients and osteotomy bone transport in 2 patients. Infection control, bone union time, time for removal of external fixation stent, complications, Sanders hip function score and Paley bone outcome score were recorded.Results:The 5 patients were followed up for (23.4±8.1) months after surgery. Infection at the fracture ends was controlled after 1 time of debridement in 3 patients and after 2 times of debridement in 2 patients. The loosening HA screws were replaced twice due to infection at the proximal nail tract, and autologous bone grafting was performed at the opposite fracture ends in 1 case; no complications occurred in the other 4 cases. Bony union was achieved at the extended segment and fracture ends in all patients. The time for imaging union after bone reconstruction was (10.2±3.4) months. The time for wearing a stent of external fixation was (18.0±4.5) months. There was no recurrent infection or lingering infection. According to the Sanders hip function score at the last follow-up, 4 cases were excellent and 1 case was good; according to the Paley bone outcome score, the curative effect was excellent in all.Conclusion:Application of a reconstruction stent of external fixation combined with antibiotic bone cement can control infection at the first stage and conduct bone reconstruction at the second stage to successfully treat the infected nonunion and preserve the hip function after internal fixation of subtrochanteric fracture.

Objective:To summarise the advantages and disadvantages of applying the method of retrograde replantation with an operative position of foot stepping and knee bending for replantation of rotational avulsed and fractured great toes.Methods:From January 2016 to June 2021, 11 rotational avulsed and fractured great toes were replanted with the method of retrograde replantation in an operative position of foot stepping and knee bending. Of the 11 patients, 10 were males and 1 was female, aged 18 to 50 years old with an average of 32 years old. Causes of injury: 5 of driving belt, 4 of machinery crush and 2 of car accident. Injury sites: 4 on left great toes and 7 on right great toes. All of the injuries were with fracture and exposure of proximal tendons of flexor and extensor. Seven patients had the follow-up reviews by outpatient clinic visiting, 2 over mobile phone and 2 via WeChat.Results:After surgery, 9 great toes completely survived and 2 great toes had necrosis. The survival rate of toe replantation was 81.8%(9/11). The operation time was 2 to 3 hours, with an average of 2.5 hours. Postoperative X-ray film showed that 8 to 12 weeks after the operation, the fracture and joint fusion were healed at first stage in the survived toes. All patients were entered in follow-up for 3 to 18 months with 10.5 months in average. The survived great toes were plump and the toenail grown well. At the final follow-up, the static TPD at the toes was 8-12 mm, with an average of 10 mm. There was no effect shown on either walking or running.Conclusion:The retrograde replantation method with an operative position of foot stepping and knee bending for great toe replantation has the characteristics of a good field of view and convenient in operation under microscope, a short operation time, and a high survival rate of replantation.

Objective:To understand the symptom clusters of patients during transcatheter arterial chemoembolization (TACE) treatment for primary liver cancer and to identify the sentinel symptoms within the symptom clusters.Methods:Using the convenient sampling method, a total of 170 patients with primary liver cancer who were admitted to the Interventional Department in Affiliated Hospital of Jiangnan University for TACE treatment from June 2022 to January 2023 were selected as research objects. From the day after TACE treatment to 4 days after surgery, M.D.Anderson Symptom Inventory-Chinese (MDASI-C) , The Symptom Module Specific to Primary Liver Cancer (TSM-PLC) and First Symptom Appearance Schedule were completed every day. Firstly, the principal component analysis method was used to determine the symptom clusters, and then the sentinel symptoms are determined based on the initial onset time of the symptoms within the cluster combined with the Apriori algorithm. A total of 170 questionnaires were distributed in this study, and 163 valid questionnaires were collected, with an effective response rate of 95.88% (163/170) .Results:A total of 5 symptom clusters were extracted, including upper gastrointestinal tract, post embolism, feeling of illness, emotion and liver function impairment. Nausea, pain, difficulty sleeping, and sadness were sentinel symptoms in the upper gastrointestinal tract, post embolism, feeling of illness and emotional symptom groups, respectively. No clear sentinel symptoms were observed in the symptom cluster of liver function impairment.Conclusions:Primary liver cancer patients have multiple symptom clusters during TACE treatment, and the determination of sentinel symptoms is of great significance in improving symptom management efficiency and nursing quality.

Objective To investigate the expression of 8-hydroxy deoxy guanosine(8-OHdG)and nectin-4 in the serum of primary liver cancer(PLC),and to evaluate the efficacy of transcatheter chemoembolization(TACE)for PLC.Methods From January 2021 to June 2022,180 patients with primary liver cancer with TACE were studied.According to the efficacy of TACE patients,they were separated into a good group(n=137)and an adverse group(n=43).The general clinical data and the serum expression levels of 8-OHdG and nectin-4 were compared between the two groups;multivariate Logistic regression was applied to analyze the influencing factors of postoperative efficacy in TACE for primary liver cancer;receiver operating characteristic was applied to analyze the value of serum 8-OHdG and nectin-4 levels in evaluating the efficacy of TACE for primary liver cancer.Results There were no significant differences in age,sex,BMI,Child-Pugh grade,tumor location,tumor number,tumor diameter,tumor contour,degree of differentiation,tumor envelope,vascular cancer thrombus,bile duct cancer thrombus and lymph node metastasis between the poor postoperative efficacy group and the good efficacy group after TACE for primary liver cancer(P＞0.05).The expression levels of serum 8-OHdG and nectin-4 in the poor postoperative efficacy group after TACE for primary liver cancer were obviously higher than those in the good efficacy group(P＜0.05).Multivariate Logistic regression analysis showed that serum 8-OHdG,nectin-4,tumor diameter,TNM staging and Lymph node metastasis were all independent influencing factors for the postoperative efficacy of TACE in primary liver cancer(P＜0.05).The AUC of the combined evaluation of serum 8-OHdG and nectin-4 for the postoperative efficacy of TACE in primary liver cancer was 0.930,with a sensitivity of 86.05％and a specificity of 94.16％,which was superior to their respective individual evaluations(Zcombination-8-OHdG=2.033,Zcombination-nectin-4=3.221,P=0.042,0.001).Conclusion The serum levels of 8-OHdG and nectin-4 are obviously increased in the poor postoperative efficacy group after TACE for primary liver cancer.The combination of the two has a good evaluation effect on the postoperative efficacy of TACE for primary liver cancer.

Objective:To evaluate the effectiveness and safety of concurrent chemoradiotherapy combined with nimotuzumab in the treatment of patients with inoperable esophageal squamous cell carcinoma (ESCC).Methods:A retrospective analysis was conducted on the clinical data of 503 patients with inoperable ESCC who underwent concurrent chemoradiotherapy in the Department of Radiation Oncology, Changzhou No. 2 People′s Hospital Affiliated to Nanjing Medical University and Department of Radiation Oncology, Affiliated Hospital of Jiangnan University from 2014 to 2020. Among these patients, 69 received concurrent chemoradiotherapy combined with nimotuzumab (the combined therapy group) and 434 received concurrent chemoradiotherapy alone (the concurrent chemoradiotherapy group). Patients of both groups were matched at a ratio of 1∶2 using the propensity score matching (PSM) method. As a result, 168 patients were determined for clinical analysis, including 61 in the combined therapy group and 107 in the concurrent chemoradiotherapy group. The short-term efficacy and adverse reactions of both groups were compared. The overall survival (OS) curves and progression-free survival (PFS) curves were plotted using the Kaplan-Meier method for the Log-rank test.Results:The two groups showed no statistical difference ( P > 0.05) in clinical baseline characteristics after the PSM. The objective response rate (ORR) of the combined therapy group was significantly higher than that of the concurrent chemoradiotherapy group with statistically significant differences (85.2% vs. 71.0%, χ2 = 4.33, P = 0.037). There was no statistical difference (98.4% vs. 91.6%, P > 0.05) in the disease control rate (DCR) between the two groups. The combined therapy group had median PFS of 28.07 months and 1-, 3-, and 5-year PFS ratios of 78.2%, 37.5% and 29.1%, respectively. The concurrent chemoradiotherapy group had mPFS of 19.54 months and 1-, 3-, and 5-year PFS ratios of 72.9%, 28.3% and 21.3%, respectively. Both groups showed statistically significant differences in PFS ( χ2 = 4.49, P = 0.034). The combined group had median OS of 34.93 months and 1-, 3-, and 5-year OS ratios of 88.5%, 46.8% and 37.4%, respectively. The concurrent chemoradiotherapy group had mOS of 24.30 months and 1-, 3-, and 5-year OS ratios of 81.3%, 35.2% and 28.0%, respectively. Both groups showed statistically significant differences in OS (χ 2= 5.11, P = 0.024), but did not show statistical differences ( P > 0.05) in the severity degree of each adverse effect during the treatment. Conclusions:Concurrent chemoradiotherapy combined with nimotuzumab can improve the ORR and prolong the PFS and OS of patients with inoperable ESCC compared with concurrent chemoradiotherapy alone. Furthermore, combining with nimotuzumab does not increase adverse effects and can be tolerated by patients with high safety.

Objective:To investigate the protective effects and mechanisms of targeted inhibition of type 3 deiodinase (Dio3) on skeletal muscle mitochondria in sepsis.Methods:① In vivo experiments: adeno-associated virus (AAV) was employed to specifically target Dio3 expression in the anterior tibial muscle of rats, and a septic rat model was generated using cecal ligation and puncture (CLP). The male Sprague-Dawley (SD) rats were divided into shNC+Sham group, shD3+Sham group, shNC+CLP group, and shD3+CLP group by random number table method, with 8 rats in each group. After CLP modeling, tibial samples were collected and Western blotting analysis was conducted to assess the protein levels of Dio3, peroxisome proliferator-activated receptor-γ coactivator-1α (PGC1α), and silence-regulatory protein 1 (SIRT1). Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was utilized to examine mRNA expression of genes including thyroid hormone receptors (THRα, THRβ), monocarboxylate transporter 10 (MCT10), mitochondrial DNA (mtDNA), and PGC1α. Transmission electron microscopy was employed to investigate mitochondrial morphology. ② In vitro experiments: involved culturing C2C12 myoblasts, interfering with Dio3 expression using lentivirus, and constructing an endotoxin cell model by treating cells with lipopolysaccharide (LPS). C2C12 cells were divided into shNC group, shD3 group, shNC+LPS group, and shD3+LPS group. Immunofluorescence colocalization analysis was performed to determine the intracellular distribution of PGC1α. Co-immunoprecipitation assay coupled with Western blotting was carried out to evaluate the acetylation level of PGC1α. Results:① In vivo experiments: compared with the shNC+Sham group, the expression of Dio3 protein in skeletal muscle of the shNC+CLP group was significantly increased (Dio3/β-Tubulin: 3.32±0.70 vs. 1.00±0.49, P < 0.05), however, there was no significant difference in the shD3+Sham group. Dio3 expression in the shD3+CLP group was markedly reduced relative to the shNC+CLP group (Dio3/β-Tubulin: 1.42±0.54 vs. 3.32±0.70, P < 0.05). Compared with the shNC+CLP group, the expression of T3-regulated genes in the shD3+CLP group were restored [THRα mRNA (2 -ΔΔCt): 0.67±0.05 vs. 0.33±0.01, THRβ mRNA (2 -ΔΔCt): 0.94±0.05 vs. 0.67±0.02, MCT10 mRNA (2 -ΔΔCt): 0.65±0.03 vs. 0.57±0.02, all P < 0.05]. Morphology analysis by electron microscopy suggested prominent mitochondrial damage in the skeletal muscle of the shNC+CLP group, while the shD3+CLP group exhibited a marked improvement. Compared with the shNC+Sham group, the shNC+CLP group significantly reduced the number of mitochondria (cells/HP: 10.375±1.375 vs. 13.750±2.063, P < 0.05), while the shD3+CLP group significantly increased the number of mitochondria compared to the shNC+CLP group (cells/HP: 11.250±2.063 vs. 10.375±1.375, P < 0.05). The expression of mtDNA in shNC+CLP group was markedly reduced compared with shNC+Sham group (copies: 0.842±0.035 vs. 1.002±0.064, P < 0.05). Although no difference was detected in the mtDNA expression between shD3+CLP group and shNC+CLP group, but significant increase was found when compared with the shD3+Sham group (copies: 0.758±0.035 vs. 0.474±0.050, P < 0.05). In the shD3+CLP group, PGC1α expression was significantly improved at both transcriptional and protein levels relative to the shNC+CLP group [PGC1α mRNA (2 -ΔΔCt): 1.49±0.13 vs. 0.68±0.06, PGC1α/β-Tubulin: 0.76±0.02 vs. 0.62±0.04, both P < 0.05]. ② In vitro experiments: post-24-hour LPS treatment of C2C12 cells, the cellular localization of PGC1α became diffuse; interference with Dio3 expression promoted PGC1α translocation to the perinuclear region and nucleus. Moreover, the acetylated PGC1α level in the shD3+LPS group was significantly lower than that in the shNC+LPS group (acetylated PGC1α/β-Tubulin: 0.59±0.01 vs. 1.24±0.01, P < 0.05), while the expression of the deacetylating agent SIRT1 was substantially elevated following Dio3 inhibition (SIRT1/β-Tubulin: 1.04±0.04 vs. 0.58±0.03, P < 0.05). When SIRT1 activity was inhibited by using EX527, PGC1α protein expression was notably decreased compared to the shD3+LPS group (PGC1α/β-Tubulin: 0.92±0.03 vs. 1.58±0.03, P < 0.05). Conclusion:Inhibition of Dio3 in skeletal muscle reduced the acetylation of PGC1α through activating SIRT1, facilitating nuclear translocation of PGC1α, thereby offering protection against sepsis-induced skeletal muscle mitochondrial damage.

Objective:To examine the clinical characteristics, the potential relative factors for postoperative abdominal septic complications, and prognosis factors of surgical recurrence of Crohn disease (CD) patients after the first surgery.Methods:All the CD patients from Department of General Surgery, Jinling Hospital, Medical School of Nanjing University who had undergone at least one abdominal surgery from January 2007 to December 2017 were included for retrospective analysis. Hospital records were reviewed for information on clinical characteristics. Relative factors of postoperative abdominal septic complications were accessed by Logistic regression models, and prognosis factors of surgical recurrence were accessed by Cox proportional hazards regression models.Results:There were 1 048 patients included (733 males and 315 females), accounting for 1 513 operations. The age was 31(17) years and the length of resected small bowel was 30.0(40.0) cm at the first resection, 20.0(35.0) cm at the second resection, and 20.0(23.5) cm at the third resection. The length of resected small bowel was 25.0(40.0) cm at any resection. At the first abdominal surgery, 70.99%(744/1 048) patients were aged between 17 and 40 years, 66.98%(702/1 048) patients had ileocolonic disease, and 60.40%(633/1 048) patients had penetrating behavior. Penetrating behavior ( OR=8.594, 95% CI: 3.397 to 21.740, P<0.01) and current smoking status ( OR=2.671, 95% CI: 1.044 to 6.832, P=0.040) were significantly associated with an increased risk of postoperative septic complications, whereas staged operation ( OR=0.360, 95% CI: 0.184 to 0.707, P=0.003) was associated with a decreased risk. Male gender ( HR=1.500, 95% CI: 1.128 to 1.995, P=0.005), upper gastrointestinal disease ( HR=1.526, 95% CI: 1.033 to 2.255, P=0.034), penetrating behavior ( HR=1.506, 95% CI: 1.132 to 2.003, P=0.005) and emergency surgery ( HR=1.812, 95% CI: 1.375 to 2.387, P<0.01) were significantly associated with an increased risk of postoperative surgical recurrence, whereas staged operation ( HR=0.361, 95% CI: 0.227 to 0.574, P<0.01) was significantly associated with a decreased risk. Conclusions:In this cohort of CD patients receiving abdominal surgery from an inflammatory bowel disease center, the median age was 31 years and the median length of resected small bowel was 30 cm, at first resection. Patients who have risk factors of adverse postoperative outcome may be benefited from staged surgical approach.
