The reprogramming of lipid metabolism is a significant factor influencing various aspects of head and neck squamous cell carcinoma,including its occurrence,development,metastasis,and resistance to radio-chemotherapy.There is a considerable elevation in the expression levels of enzymes and genes related to lipid metabolism in tumor tissues compared to normal tissues.This up-regulation is associated with both treatment resistance and a poor prognosis.This review focuses mainly on alterations in lipid metabolism in head and neck squamous cell carcinoma.It systematically explores the atypical expression and clinical significance of lipid metabolism-related enzymes,evaluates their influence on treatment resistance,elucidates the underlying mechanisms of this resistance,and discus-ses current and potential targeted therapeutic approaches.The comprehensive analysis comprises four pivotal aspects:de novo lipogene-sis,fatty acid oxidation,glycerophospholipids metabolism,and mevalonate and cholesterol synthesis pathways.Feasible strategies,such as the adjustment of dietary structure,the administration of multi-target drugs,and the utilization of combination treatment thera-pies,are deliberated as potential interventions to modulate lipid metabolism,reverse treatment resistance,and enhance the efficacy of anti-cancer treatments.

Objective: To investigate the impact of molecular classification and key oncogenes on the oncologic outcomes in patients with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) receiving fertility-preserving treatment. Methods: Patients with EC and AEH undergoing progestin-based fertility-preserving treatment and receiving molecular classification as well as key oncogenes test at Obstetrics and Gynecology Hospital, Fudan University from January 2021 to March 2023 were reviewed. Hysteroscopic lesion resection and endometrial biopsy were performed before initiating hormone therapy and every 3 months during the treatment to evaluate the efficacy. The risk factors which had impact on the treatment outcomes in EC and AEH patients were further analyzed. Results: Of the 171 patients analyzed, the median age was 32 years, including 86 patients with EC and 85 patients with AEH. The distribution of molecular classification was as follows: 157 cases (91.8%) were classified as having no specific molecular profile (NSMP); 9 cases (5.3%), mismatch repair deficient (MMR-d); 3 cases (1.8%), POLE-mutated; 2 cases (1.2%), p53 abnormal. No difference was found in the cumulative 40-week complete response (CR) rate between the patients having NSMP or MMR-d (61.6% vs 60.0%; P=0.593), while the patients having MMR-d had increased risk than those having NSMP to have recurrence after CR (50.0% vs 14.4%; P=0.005). Multi-variant analysis showed PTEN gene multi-loci mutation (HR=0.413, 95%CI: 0.259-0.658; P<0.001) and PIK3CA gene mutation (HR=0.499, 95%CI: 0.310-0.804; P=0.004) were associated with a lower cumulative 40-week CR rate, and progestin-insensitivity (HR=3.825, 95%CI: 1.570-9.317; P=0.003) and MMR-d (HR=9.014, 95%CI: 1.734-46.873; P=0.009) were independent risk factors of recurrence in EC and AEH patients. Conclusions: No difference in cumulative 40-week CR rate is found in the patients having NSMP or MMR-d who received progestin-based fertility-preserving treatment, where the use of hysteroscopy during the treatment might be the reason, while those having MMR-d have a higher risk of recurrence after CR. Oncogene mutation of PTEN or PIK3CA gene might be associated with a lower response to progestin treatment. The molecular profiles help predict the fertility-preserving treatment outcomes in EC and AEH patients.

Objective: To investigate the effects of application of citrate anticoagulation in bedside continuous blood purification (CBP) of severe burn patients with sepsis, so as to provide reference for choosing anticoagulants in CBP of these patients. Methods: Thirty severe burn patients with sepsis, conforming to the study criteria, were admitted to our burn intensive care unit from January 2014 to July 2017. Patients were divided into heparin group and citrate group according to computer randomization method, with 15 cases in each group. Patients in two groups all received bedside CBP treatment. Patients in heparin group used local heparin anticoagulation, while patients in citrate group used local citrate anticoagulation. Time of predicted single-time CBP treatment, time of single-time CBP treatment, time of accumulative CBP treatment, and rate of reaching the standard of CBP treatment time were counted. Changes of prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), fibrinogen, serum procalcitonin, and C-reactive protein (CRP) of patients before and after treatment were monitored. Hemorrhage in wounds, incision on trachea, and arteriovenous intubation point, and other complications during and after CBP treatment were observed. Data were processed with independent sample t test and chi-square test. Results: (1) Time of predicted single-time CBP treatment of patients in the two groups was equal. Time of single-time CBP treatment and time of accumulative CBP treatment of patients in citrate group were longer than those in heparin group. Rate of reaching the standard of CBP treatment time of patients in citrate group was significantly higher than that in heparin group (χ²=16.655, P<0.01). (2) There was no statistically significant difference in PT, APTT, INR, fibrinogen, serum procalcitonin, and CRP of patients in the two groups before CBP treatment (t=0.203, -1.006, 0.203, 0.039, -1.591, -0.824, P>0.05). PT and APTT of patients in citrate group after CBP treatment were (14.2±1.6) and (45±7) s, respectively, significantly shorter than (15.5±1.4) and (53±6) s in heparin group (t=2.395, 3.321, P<0.05 or P<0.01). INR of patients in citrate group after CBP treatment was 1.13±0.12, significantly lower than 1.24±0.12 in heparin group (t=2.395, P<0.05). Fibrinogen of patients in citrate group after CBP treatment was (3.5±0.6) g/L, significantly higher than (3.0±0.6) g/L in heparin group (t=-2.427, P<0.05). Serum procalcitonin and CRP of patients in citrate group after CBP treatment were significantly lower than those in heparin group (t=2.520, 2.710, P<0.05). Decreased degree of serum procalcitonin and CRP of patients in citrate group after CBP treatment were (1.8±0.6) ng/mL and (143±69) mg/L, respectively, significantly higher than (0.9±0.6) ng/mL and (95±50) mg/L in heparin group (t=-4.033, -2.170, P<0.05 or P<0.01). (3) During CBP treatment, patients in heparin group experienced 21 times of exacerbation of wound hemorrhage and 10 times of new hemorrhage, including 2 times of hemorrhage at incision on trachea and 8 times of hemorrhage at arteriovenous intubation point. No exacerbation of hemorrhage or new hemorrhage happened in patients of citrate group. After CBP treatment, no electrolyte disturbance happened in patients of heparin group, but 1 patient in citrate group experienced hypocalcemia. Conclusions Application of citrate anticoagulation in bedside CBP of severe burn patients with sepsis shows light impact on systematic coagulation status, and can effectively decrease inflammation reaction of burn sepsis with low rate of hemorrhage.

Objective To assess the value of free-hand transperineal multiparametric nagnetic resonance imaging/transrectal ultrasound (mpMRI/TRUS) fusion-guided targeted biopsy (TB) for the diagnosis of prostate cancer(PCa).Methods Patients with elevated PSA level and/or an abnormal DRE finding were recruited prospectively between January 2015 and September 2016.Patients were classified to various scores from 2 to 5 according to prebiopsy mpMRI PI-RADS.Based on free-hand transperineal mpMRI/TRUS fusion-guiding,a 2-cores TB for each cancer-suspicious lesion were carried out and followed 12-cores systematic biopsy (SB) protocol.Pathological findings of biopsy and radical prostatectomy (RP) specimens were analyzed.Results A total of 397 patients were enrolled in this study.The median age of the patients was (68.2 ± 7.4) years old,ranging 42-78 years.The median PSA level was (15.0 ±12.4)ng/ml,ranging 3.0-88.3 ng/ml.DRE showed abnormality in 28 patients(7.1％).The median prostate volume was (41.6 ± 16.4)cm3,ranging 24.6-89.8 cm3.The PCa detection rate of TB was significantly increased compared with SB (44.8 ％ vs.34.8％) (P =0.003),especially in clinically significant PCa (P ＜ 0.001) and intermediate/high-risk PCa (P =0.003),respectively.Of the all 588 mpMRI targeted lesions,277 lesions were positive.A total of 105 index tumors were identified in RP specimens,the locations of TB-proven cancer showed 96.6％ (85/88) in correspondence with the location of the index lesion in RP specimens.Conclusions Free-hand transperineal mpMRI/TRUS fusion-guided TB providing greater detection of intermediate-high risk PCa while limits over detection of low risk PCa.Moreover,TB can reliably predict the location of an index tumor.

Objective To explore the effect of " hospital informationized blood glucose management" on perioperative diabetic patients. Methods Three hundred patients with type 2 diabetes mellitus, who underwent selective operations from orthopedics, general surgery, urological surgery, and thoracic surgery were divided into two groups: 150 cases of blood glucose information management group and 150 cases of traditional blood glucose monitoring and management group. The blood glucose on target rate, percent of hypoglycemic events, percent of hyperglycemic events, the blood glucose level on the first postoperative day, the average hospitalization day, perioperative infection rate were evaluated for efficacy. Results The blood glucose on target rate in informationized blood glucose management group was significantly higher than that of the control group [(52.52 ± 18.31)%vs (14.88 ± 8.39)%, P＜0.01]. The frequency of hyperglycemia, the average daily blood glucose, the average blood glucose on fasting, after three meals and at night, the fasting and postprandial blood glucose level on the first postoperative day in informationized blood glucose management group were significantly lower than that of the control group [( 45. 31 ± 18.87)%vs (84.41±8.86)%, (8.59±1.34 vs 12.47±2.37) mmol/L, (7.33±1.41 vs 10.01±1.99)mmol/L, (8.89 ±2.34vs13.61±3.47)mmol/L,(9.47±1.94vs13.46±2.77)mmol/L,(9.40±2.72vs13.28±2.94)mmol/L, (8.28±2.11vs11.31±2.89)mmol/L,(8.29±2.51vs11.58±3.52)mmol/L,(8.25±3.67vs17.65±19.68) mmol/L, all P＜0.01]. In addition, the average hospitalization day of the informationized blood glucose management group was significantly shorter than that of the control group [(16±7 vs 21±15)d, P＜0.05]. The infection rate of the management group and the control group were 41. 2% and 58. 8% respectively. There was no significant difference between two groups (P＞0.05). Conclusion The " hospital informationized blood glucose management" is simple and practical, which may significantly improve the rate of blood glucose control in each period, reduce the average hospitalization day, and decrease perioperative infection tendency.

Objective To investigate the effect of lumboperitoneal (L-P) shunt and ventriculoperitoneal(V-P) shunt for trea-ting the patients with communicating hydrocephalus .Methods The databases of PubMed ,Web of Science ,Scopuss ,Karge , EBSCO+MEDLINE ,OVID ,EMBASE ,CNKI ,CBM disc databases ,Wanfang databases ,Weipu databases were retrieved by com-puter .The relevant literatures about L-P shunt and V-P shunt for treating communicating hydrocephalus included in these databases during 1990-2016 were collected and performed the meta analysis by using the STATA 12 .0 software .Results The success rate of L-P shunt in treating communicating hydrocephalus was apparently higher than that of V-P shunt(P<0 .05) .Moreover ,postopera-tive infection rate ,obstruction rate of shunt system and total postoperative complications rate in L-P shunt were apparently lower than those of V-P shunt(P<0 .05) ,However ,there was no statistical difference in shunt poor rate between L-P shunt and V-P shunt(P>0 .05) .Conclusion L-P shunt is worth recommending .But due to lower quality of the evidences ,it is needed more high quality primary studies to remedy the insufficiency of the study .

Objective To explore selection of the procedures in one stage urethroplasty for treatment of the coexistence of urethral strictures in anterior and posterior urethra.Methods Between January 2008 and December 2014, a total of 27 patients with coexist strictures simultaneously in anterior urethra and posterior urethra were treated in our hospital.The mean age was 38 years old (ranging 13-83 years old.Stricture etiology was secondary to lichen sclerosus in 2 patients, iatrogenic in 3 and posttraumatic in 22.The mean length of urethral stricture was 11cm (ranging 6-14cm).Two procedures for treatment of anterior urethral stricture, including augmentation of urethroplasty using penile skin flap was performed in 20 patients and augmentation of urethroplasty using lingual mucosa in 7.Three procedures for treatment of posterior urethral stricture, including non-transecting spongiosum end to end anastomosis of the two urethral ends was performed in 3 patients, end to end anastomosis of the two urethral ends was performed in 17 and substitution urethroplasty using different tissues was performed in reminder 7 patients.Of them, pedicle scrotal skin urethroplasty was performed in 2 patients and lingual mucosal graft urethroplasty in 5 patients.Results The patients were mean followed up 2.6 years (ranging 0.545.0 years) with an overall success rate of 88.9％ (24 of 27 cases).Complications developed in 3 patients (11.1％).Of the 17 patients with end to end anastomosis, urethral stricture developed respectively 4 and 6 months in 2 patients and voiding well after pedicle scrotal skin urethroplasty.Urethral pseudodiverticulum developed 9 months after pedicle penile flap urethroplasty in another patient and voiding well after urethroplasty.Urethrography showed patent urethra with adequate lumen in the remaining patients and mean urinary peak flows was 21.3 ml/s (ranging 14.2-37.9 ml/s).Conclusions Substitution urethroplasty using penile skin or oral mucosa was more good procedure for anterior urethral stricture during the treatment of the coexistence of urethral stricture in the anterior and posterior urethra.The treatment of posterior urethral stricture was based on the length of the stricture, local condition to make a choice between anastomotic urethral reconstruction and substitution urethroplasty using other tissue.

BACKGROUNDThere are limited data on longer-term outcomes (>5 years) for patients with unprotected left main coronary artery (ULMCA) disease who underwent percutaneous coronary intervention (PCI) in the drug-eluting stents (DES) era. This study aimed at comparing the long-term (>5 years) outcomes of patients with ULMCA disease underwent PCI with DES and coronary artery bypass grafting (CABG) and the predictors of adverse events.

METHODSAll consecutive patients with ULMCA disease treated with DES implantation versus CABG in our center, between January 2003 and July 2009, were screened for analyzing. A propensity score analysis was carried out to adjust for potential confounding between the two groups.

RESULTSNine hundred and twenty-two patients with ULMCA disease were enrolled for the analyses (DES = 465 vs. CABG = 457). During the median follow-up of 7.1 years (interquartile range 5.3-8.2 years), no difference was found between PCI and CABG in the occurrence of death (P = 0.282) and the composite endpoint of cardiac death, myocardial infarction (MI) and stroke (P = 0.294). Rates of major adverse cardiac and cerebrovascular events were significantly higher in the PCI group (P = 0.014) in large part because of the significantly higher rate of repeat revascularization (P < 0.001). PCI was correlated with the lower occurrence of stroke (P = 0.004). Multivariate analysis showed ejection fraction (EF) (P = 0.012), creatinine (P = 0.016), and prior stroke (P = 0.031) were independent predictors of the composite endpoint of cardiac death, MI, and stroke in the DES group, while age (P = 0.026) and EF (P = 0.002) were independent predictors in the CABG group.

CONCLUSIONSDuring a median follow-up of 7.1 years, there was no difference in the rate of death between PCI with DES implantation and CABG in ULMCA lesions in the patient cohort. CABG group was observed to have significantly lower rates of repeat revascularization but higher stroke rates compared with PCI. EF, creatinine, and prior stroke were independent predictors of the composite endpoint of cardiac death, MI, and stroke in the DES group, while age and EF were independent predictors in the CABG group.
