Hepatocellular carcinoma(HCC)expresses abundant glycolytic enzymes and displays comprehensive glucose metabolism reprogramming.Aldolase A(ALDOA)plays a prominent role in glycolysis;however,little is known about its role in HCC development.In the present study,we aim to explore how ALDOA is involved in HCC proliferation.HCC proliferation was markedly suppressed both in vitro and in vivo following ALDOA knockout,which is consistent with ALDOA overexpression encouraging HCC prolifera-tion.Mechanistically,ALDOA knockout partially limits the glycolytic flux in HCC cells.Meanwhile,ALDOA translocated to nuclei and directly interacted with c-Jun to facilitate its Thr93 phosphorylation by P21-activated protein kinase;ALDOA knockout markedly diminished c-Jun Thr93 phosphorylation and then dampened c-Jun transcription function.A crucial site Y364 mutation in ALDOA disrupted its interaction with c-Jun,and Y364S ALDOA expression failed to rescue cell proliferation in ALDOA deletion cells.In HCC patients,the expression level of ALDOA was correlated with the phosphorylation level of c-Jun(Thr93)and poor prognosis.Remarkably,hepatic ALDOA was significantly upregulated in the promotion and progression stages of diethylnitrosamine-induced HCC models,and the knockdown of Aldoa strikingly decreased HCC development in vivo.Our study demonstrated that ALDOA is a vital driver for HCC development by activating c-Jun-mediated oncogene transcription,opening additional avenues for anti-cancer therapies.

Objective To analyze the acupoint selection law of acupuncture and moxibustion for postherpetic neuralgia(PHN)with R language data mining technology.Methods The clinical research literature on acupuncture and moxibustion treatment of PHN included in CNKI,Wanfang Data,VIP and CBM from January 1,2010 to July 1,2023 was retrieved,and the database was established by Excel 2016.R language was used to statistically analyze the frequency of acupoint usage,meridians,locations,specific acupoints,etc.Through association rule analysis and clustering analysis,the characteristics and law of acupoint selection for acupuncture and moxibustion treatment of PHN were obtained.Results A total of 198 articles were included,including 83 acupoints,with a total frequency of 714 times.The high-frequency acupoints include Ashi acupoint,Jiaji acupoint and Yanglingquan.The commonly used meridians were gallbladder meridian,spleen meridian and large intestine meridiam.The acupoints were mostly in the upper and lower limbs,with the Wushu acupoints,Yuan acupoints and Xiahe acupoints being the most common.The core acupoint was Ashi acupoint,Jiaji acupoint,Hegu,Quchi,and 9 sets of association rules and 5 effective clusters were obtained.Conclusion The most commonly used acupoints for acupuncture and moxibustion treatment of PHN are Ashi acupoint,Jiaji acupoint,Hegu and Quchi,which mainly follow the principle of combining local acupoint selection with distal acupoint selection.

Aim To investigate the impact of G pro-tein-coupled estrogen receptor 1(GPER1),also known as GPR30 playing a significant role in the nerv-ous system,on neuronal damage and cognitive dysfunc-tion following epileptic seizures.Methods The pro-tein expression levels of GPER1 and the DNA damage marker γ-H2AX in epileptic rats were assessed using Western blot.The hippocampal neuronal damage and apoptosis in pilocarpine-induced epilepsy models were evaluated using Nissl and TUNEL staining techniques,compared with GPER1 knockdown(GPER1-KD)rats with wild-type(WT)controls.The behavioral activi-ties,including memory and spatial learning,were mo-nitored during the chronic phase of epilepsy using the IntelliCage system.Results Compared to the control group,GPER1 protein expression in the cerebral cortex and hippocampus significantly increased 24 hours post-epilepsy onset.In the GPER1-KD+EP group,hipp-ocampal neuronal damage was more severe,with a sig-nificant increase in apoptotic neurons compared to the WT+EP group.The IntelliCage data revealed that during free exploration,nose contact,position learn-ing,and reverse position learning stages in the GPER1-KD+EP group exhibited fewer visits and a higher error rate than in the WT+EP group.Conclu-sions Deficiency in GPER1 impairs memory and spa-tial learning abilities following epilepsy,potentially due to exacerbated neuronal injury,apoptosis,and inflam-mation.GPER1 represents a promising therapeutic tar-get for mitigating post-epileptic nerve damage and cog-nitive impairment.

Objective Evaluation of the off-label use of flupentixol melitracen based on an evidence-based medicine approach and recommendations for graded management.Methods The off-label prescriptions of flupentixol melitracen for outpatient clinics in our hospital from November 1,2023,to October 31,2024,were collected to count the clinical diagnoses of off-label use of flupentixol melitracen tablets.Searching foreign drug manuals,authoritative medical monographs,as well as guidelines and literature databases such as the US National Guidelines Clearinghouse(NGC),Guidelines International Network(GIN),Medlive,Yaozh.com,PubMed,Cochrane Library,Embase,WanFang Data,VIP,CNKI and other guidelines and literature databases,to collect literature on evidence-based medical evidence related to the flupentixol melitracen tablets for off-label use.The literature was screened according to the pre-established inclusion and exclusion criteria,and the quality of evidence was assessed and graded to determine the evidence of evidence-based medicine for off-label use,and to make recommendations for grading management.Results Flupentixol melitracen tablets off-label use involves 13 clinical diagnoses of gastritis,sleep disorders,dizziness,neurological disorders,gastroesophageal reflux,gastrointestinal disorders,headache(tension-type headache),abdominal pain(functional abdominal pain syndrome),palpitations,constipation,neurasthenia,cardiac neurosis,and neuralgia.A total of 8 evidence-based medical literature related to off-label use were included,including 4 guidelines,1 Meta-analysis,and 3 clinical randomised controlled trials(RCTs).Based on the evaluation of evidence-based medicine methodology,the quality grade of a Meta-analysis was extremely low,and 3 RCTs were at high risk of bias.There was evidence-based medical evidence for the determination of treating chronic gastritis,which is recommende as level A management and agreed to be used.There was evidence-based medical evidence for the adjudication of treating sleep disorders,headache(tension-type headache),abdominal pain(functional abdominal pain syndrome),neuralgia,and chronic constipation,which was recommended as level B management and restriction for use.There was no evidence-based medical evidence for the remaining off-label uses of the drug.Conclusion The evidence-based medicine evidence for flupentixol melitracen in the treatment of chronic gastritis,sleep disorders,headache,abdominal pain,neuralgia,and chronic constipation are relatively sufficient and their use are reasonable,while the rationale for other off-label use are relatively low and are recommended to be contraindicated.Through the evidence-based medicine methods,the evaluation system for off-label use of flupentixol melitracen has been improved,providing a basis for rational clinical medication and ensuring the safety of patients' medication.

BACKGROUND:Large deep burn wounds are often accompanied by scar hyperplasia after healing,requiring transplantation of medium-thickness skin for repair,and the medium-thickness skin slices taken generally reach below the papillary layer of the dermis.If not handled correctly,complications such as delayed healing,ulceration,and post-healing pain and itching in the donor area can easily occur.Therefore,the repair of wounds in the donor area should be emphasized.OBJECTIVE:To observe the safety and practicability of autologous scalp repair of skin donor area in patients with deep burns and scarring.METHODS:Sixty patients with deep burn and scar hyperplasia admitted to the Burn Department of Zhengzhou First People's Hospital from January 2021 to September 2023 were selected as the study subjects.They all needed medium-thickness skin transplantation and repair,and were divided into study group(n=30)and control group(n=30)according to random systematic sampling method.The skin was taken from the patient's own medium-thickness skin on the leg or back.In the study group,the skin donor area was repaired with self-blade thick scalp replantation,and in the control group,the skin donor area was repaired with absorbent dressing.The wound healing rate and the time to complete epithelialization of the wound were observed and compared in the two groups 6 days after surgery.The pain of dressing change at 3 and 6 days after surgery and scar hyperplasia in the skin donor area at 6 months after surgery were compared between two groups.RESULTS AND CONCLUSION:Compared with the control group,the time to complete epithelialization of the wound was significantly lower in the study group(P<0.05),and the wound healing rate was significantly higher in the study group(P<0.05),the pain score for dressing change at 3 and 6 days after surgery was significantly lower in the study group(P<0.05),and the scar hyperplasia rate,scar score and itch score were also significantly lower in the study group(P<0.05)at 6 months after surgery.In conclusion,autologous scalp repair of the medium-thickness skin donor area can accelerate wound healing and reduce scar hyperplasia.

The incidence and mortality of colorectal cancer （CRC） in China have been on a steady rise. Current therapeutic approaches can curb the progression of CRC to a certain extent， but issues such as toxic side effects， high metastasis rate， and high recurrence rate cannot be ignored. In recent years， alkaloid components derived from traditional Chinese medicine （TCM） have demonstrated tremendous potential in the prevention and treatment of CRC due to their diverse structures， complex mechanisms， and broad biological activities. Representative alkaloids such as matrine， berberine and evodiamine exert anti-CRC effects through multiple pathways： regulating signaling pathways including Wnt/β-catenin， nuclear factor-κB， signal transducer and activator of transcription 3， and phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin； inhibiting the proliferation， migration， and invasion of CRC cells； inducing cell apoptosis and autophagy； arresting the cell cycle progression； regulating the gut microbiota； suppressing cellular glycolysis； and inducing ferroptosis.

Objective:To evaluate the relationship between the mechanism of ω-3 polyunsaturated fatty acids (ω-3 PUFAs) in preventing brain neurotoxicity caused by multiple sevoflurane anesthesia and peroxisome proliferator-activated receptor gamma (PPARγ)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α) signaling pathway in neonatal mice.Methods:This study was performed in 2 parts. Part Ⅰ Using a random number table method, 6 C57BL/6 pregnant mice were assigned to receive a standard diet, 3 pregnant mice were assigned to receive a diet supplemented with fish oil from day 2 of gestation to day 14 after parturition (ω-3 PUFAs 300 mg were added to every 20 g of conventional diet). Healthy C57BL/6 mice of both sexes, aged 6 days, weighing 3-5 g, were selected after parturition. Seventeen neonatal pups from 3 pregnant mice that were fed a conventional diet were assigned to control group (C group), 17 neonatal pups from 3 pregnant mice that were fed a conventional diet were assigned to sevoflurane group (S group), and 17 neonatal pups from pregnant mice that were fed a diet supplemented with fish oil were assigned to ω-3 PUFAs plus sevoflurane group (PS1 group) using the random number table method. Part Ⅱ Four C57BL/6 pregnant mice were assigned to receive a diet supplemented with fish oil from day 2 of gestation to day 14 after parturition. After parturition, 12 neonatal pups from 2 pregnant mice that were fed a diet supplemented with fish oil were assigned to ω-3 PUFAs plus sevoflurane group (PS2 group), and 12 neonatal pups from 2 pregnant mice that were fed a diet supplemented with fish oil were assigned to ω-3 PUFAs plus PPARγ inhibitor GW9662 plus sevoflurane group (PGS group) using a random number table method. GW9662 (2 mg/kg) was intraperitoneally injected at 30 min before exposure to sevoflurane in PGS group. All offspring mice were breastfed until 21 days of age, after which they were housed separately from the mother and allowed ad libitum access to a conventional diet. S, PS1, PS2 and PGS groups inhaled 3% sevoflurane in 40% oxygen for 2 h daily on postnatal days 6, 7 and 8. C group inhaled only 40% oxygen instead. Y maze test was performed on days 33 after birth. The rotarod test was performed on day 35 after birth. After the behavioral testing, the expression of PPARγ, PGC1α, mitofusin-1 (MFN1), MFN2, dynamin-related protein 1 (DRP1), interleukin-6 (IL-6), interleukin-1 β (IL-1 β), and tumor necrosis factor-α (TNF-α) was detected by Western blot, the ultrastructure of mitochondria in hippocampal neurons was observed with a transmission electron microscope, and the mitochondrial membrane potential (MMP), level of reactive oxygen species (ROS) and content of ATP were determined.Results:Part Ⅰ Compared with C group, the time of stay at the new-arm and time spent on the rotarod were significantly shortened, the percentage of movement distance in the new-arm was decreased, the expression of PPARγ, PGC1α, MFN1 and MFN2 in the hippocampus was down-regulated, the expression of DRP1, IL-6, IL-1β and TNF-α in the hippocampus was up-regulated, the MMP and content of ATP were decreased, and the level of ROS was increased in S group ( P<0.05). Compared with S group, the time of stay at the new-arm and time spent on the rotarod were significantly prolonged, the percentage of movement distance in the new-arm was increased, the expression of PPARγ, PGC1α, MFN1 and MFN2 in the hippocampus was up-regulated, the expression of DRP1, IL-6, IL-1β and TNF-α in the hippocampus was down-regulated, the MMP and content of ATP were increased, and the level of ROS was decreased in PS1 group ( P<0.05). Part Ⅱ Compared with PS2 group, the time of stay at the new-arm and time spent on the rotarod were significantly shortened, the percentage of movement distance in the new-arm was decreased, the MMP and content of ATP were decreased, the level of ROS was increased, and the expression of IL-6, IL-1β and TNF-α was up-regulated ( P<0.05). Conclusions:The mechanism by which ω-3 PUFAs prevent brain neurotoxicity caused by multiple sevoflurane anesthesia is related to the activation of the PPARγ/PGC1α signaling pathway and alleviation of mitochondrial dysfunction and neuroinflammation in neonatal mice.

Objective:To evaluate the role of docosahexaenoic acid (DHA) in long-term cognitive impairment after multiple sevoflurane anesthesia in newborn mice.Methods:Clean-grade healthy male C57BL/6 mice, aged 6 days, were used in this study. Ten mice were divided into 2 groups ( n=5 each) by the random number table method: control group (group C) and sevoflurane group (group S). The animals inhaled 3% sevoflurane for 2 h at 6, 7 and 8 days after birth. The DHA content was detected by ultra-high performance liquid chromatography-mass spectrometry at 9 days of age. Fifty-two mice were selected and divided into 4 groups ( n=13 each) by a random number table method: control+ normal saline group (group C+ S), sevoflurane anesthesia + normal saline group (group S+ S), control+ DHA group (group C+ D), and sevoflurane anesthesia+ DHA group (group S+ D). The sevoflurane anesthesia method was the same as the one mentioned above. DHA 50 mg/kg was administered by intragastric gavage from postnatal days 6-19 (at 6, 7 and 8 days after birth, 2 h before anesthesia) in C+ D and S+ D groups. The equal volume of normal saline was given instead in C+ S group and S+ S group. The novel object recognition test was conducted at 37 days of age, and the Morris water maze test was performed at 42 days of age. The corpus callosum and hippocampal tissues were isolated at 47 days of age for examination of the ultrastructure of myelin (with a transmission electron microscope) and for determination of the expression of myelin basic protein (MBP) in hippocampal tissues (by Western blot). The G-ratio was calculated. Results:Compared with group C, the content of DHA in hippocampal tissues was significantly decreased in group S ( P<0.05). Compared with group C+ S, the discrimination index was significantly decreased, the percentage of duration of staying at the target platform quadrant and the number of crossing the original platform were decreased, the expression of MBP was down-regulated, and the G-ratio in the original platform and hippocampus was increased in S+ S group ( P<0.05). Compared with group S+ S, the discrimination index was significantly increased, the percentage of duration of staying at the target platform quadrant and the number of crossing the original platform were increased, the expression of MBP was up-regulated, and the G-ratio in the original platform and hippocampus was decreased in S+ D group ( P<0.05). Conclusions:The mechanism of long-term cognitive impairment following multiple sevoflurane anesthesia may be related to a decrease in the content of DHA, which subsequently leads to myelin structural damage in neonatal mice.

Objective:To evaluate the relationship between preoperative gut microbiota and post-operative ventilator-associated pneumonia (VAP) in patients undergoing coronary artery bypass grafting.Methods:This was a secondary analysis of a previous research project study. Patients who received invasive mechanical ventilation treatment after elective off-pump coronary artery bypass grafting at the Second Hospital of Hebei Medical University from April to September 2023 were selected and divided into VAP group and non-VAP group based on whether VAP occurred after surgery. Fecal samples were collected from patients before surgery, and 16S rRNA gene sequencing was used to analyze the characteristics of preoperative gut microbiota in the two groups. The differences in the diversity of gut microbiota between the two groups were compared. The linear discriminant analysis was used to identify the gut microbiota with significant differences between groups (differential bacteria), and logistic regression analysis was conducted to assess the association between differential bacteria and VAP. Receiver operating characteristic curves were drawn to analyze the predictive value of the differential bacteria for VAP.Results:A total of 79 patients were finally included, with 25 in VAP group and 54 in non-VAP group. The Beta diversity analysis showed statistically significant differences between VAP group and non-VAP group (pseudo- F=2.00, P=0.002). The linear discriminant analysis indicated that Bifidobacterium, Blautia and Megamonas were enriched in non-VAP group, while Klebsiella was enriched in VAP group. Multivariate logistic regression analysis showed that the relative abundance of Bifidobacterium was a protective factor for postoperative VAP ( OR=0.32, 95% confidence interval [ CI] 0.15-0.71, P=0.005), and the relative abundance of Klebsiella was a risk factor for postoperative VAP ( OR=2.49, 95% CI 1.143-5.43, P=0.022). The area under the receiver operating characteristic curve of the relative abundance of Bifidobacterium for predicting VAP was 0.80 (95% CI 0.69-0.90, P<0.001) and of the relative abundance of Klebsiella was 0.70 (95% CI 0.57-0.83, P=0.005). Conclusions:Bifidobacterium is a protective factor, while Klebsiella is a risk factor for postoperative VAP in patients undergoing coronary artery bypass grafting, and the relative abundance of both bacteria has a certain predictive value for VAP.

Objective:To investigate the clinical and pathological characteristics, prognostic factors, and treatment outcomes of bladder adenocarcinoma.Methods:The data of 177 bladder adenocarcinoma patients treated at Renji Hospital, Shanghai Jiaotong University School of Medicine from January 2003 to December 2023, and 2 687 bladder adenocarcinoma patients from the SEER database (2000—2021) were reviewed retrospectively. The clinicopathological and prognostic characteristics were compared between the two cohorts. Patients with urachal adenocarcinoma or primary bladder adenocarcinoma were included, while metastatic bladder adenocarcinoma from other sites and urothelial carcinoma with glandular components were excluded. The Chi-square test was used for comparison of categorical data, and propensity score matching (1∶1) was applied to match baseline data between the Renji and SEER cohorts. Kaplan-Meier survival curves were generated, and log-rank tests were used for comparisons. Univariate and multivariate Cox regression analyses were performed using the survival R package, with P-values calculated via Wald tests. Results:The proportion of localized bladder adenocarcinoma was significantly higher in the Renji cohort than in the SEER cohort [61.0% (108/177) vs. 19.4% (521/2 687), P<0.001], and mucinous adenocarcinoma was more common in Renji cohort [33.3% (59/177) vs. 22.6% (607/2 687), P<0.001]. After matching for baseline factors, including SEER stage and pathological grade, survival analysis revealed that the Renji cohort patients had slightly better survival compared to the SEER cohort [median survival: 55.4 (24.1, 196.2) months vs. 39.2 (13.6, 137.4)months, P=0.033]. Multivariate Cox analysis identified SEER stage [Renji cohort: HR=3.83 (95% CI 1.62-9.07), P=0.002; SEER cohort: HR=3.67 (95% CI 3.13-4.31), P<0.001] and pathological grade [Renji cohort: HR = 2.76 (95% CI 1.54-4.95), P=0.001; SEER cohort: HR=1.46 (95% CI 1.29-1.65), P<0.001] as independent prognostic factors. In the Renji cohort, no significant differences were observed in the median progression-free survival [40.1 (19.5, 91.6) months vs. 40.9 (12.8, not reached)months, P=0.976] and overall survival [79.3 (37.1, 195.8) months vs. 53.9 (16.4, 129.5)months, P=0.374] between patients receiving adjuvant chemotherapy and those not receiving it. However, among patients with lymph node-positive bladder adenocarcinoma, adjuvant chemotherapy significantly improved both progression-free survival [40.1 (38.2, 75.4) months vs. 12.2 (3.1, 12.2)months, P=0.004] and overall survival [68.2 (46.2, 84.5)months vs. 28.1 (4.3, 28.3)months, P=0.006]. Conclusions:Bladder adenocarcinoma is rare and associated with poor prognosis. Compared to the SEER cohort, Renji cohort patients had more localized disease, with no significant differences in other features. SEER stage and pathological grade were independent prognostic factors in both cohorts. Lymph node-positive bladder adenocarcinoma patients in the Renji cohort benefited significantly from adjuvant chemotherapy.
