Objective:To investigate the efficacy and safety of endoscopic resection of infratemporal fossa mass and to determine the indications for surgery.Methods:A retrospective case series study was conducted, including a total of 29 patients who underwent endoscopic surgery to treat infratemporal fossa mass in the Department of Rhinology of Beijing Tongren Hospital, Capital Medical University, from April 2008 to December 2021. Ten males and 19 females were included in the study, with age of (46.5±13.7) years. Pre-and post-operative sinus CT, sinus or nasopharyngeal enhanced MRI were evaluated, respectively. The main outcome measurements were the total resection of mass and the incidence of surgery-related complications.Results:Among the 29 cases of infratemporal fossa mass, 22 were schwannomas, 3 were cysts, 2 were neurofibromas, 1 was pleomorphic adenoma and 1 was basal cell adenoma. Preoperative imaging showed well-defined lesion boundaries, and postoperative pathology confirmed the benign nature of all cases. The endoscopic transnasal approach was used in 28 patients, while the combination of the transnasal approach and the transoral approach was used in 1 patient. Complete tumor removal was achieved in all cases with a 100% resection rate. The average follow-up time was 38 months (7-168 months), and no tumor recurrence was observed.Conclusions:The Endoscopic transnasal approach is a safe and effective surgical approach for the treatment of benign tumors or masses in the infratemporal fossa.

Objective:To analyze the efficacy of endoscopic surgery for frontal sinus meningoencephalocele and cerebrospinal fluid (CSF) leaks, and to explore endoscopic surgical strategy.Methods:A total of 35 patients with frontal sinus meningoencephalocele and CSF leaks who underwent endoscopic transnasal surgery at Beijing Tongren Hospital, Capital Medical University between May 2007 and December 2023 were enrolled in this retrospective case series, including 29 males and 6 females, with the age of (35.23±15.76) years. High-resolution sinus CT and magnetic resonance cisternography were undertaken before surgery. The primary outcome measure was the success rate of endoscopic surgical repair. Statistical analysis was conducted using SPSS 27 and GraphPad Prism 8 software.Results:Of the 35 cases, 21 (60.0%) were traumatic, and 14 (40.0%) were non-traumatic. The most common defect was in the posterior frontal sinus wall (24 cases, 68.6%), with a defect size of (10.4±4.8) mm 2. Twenty-six cases (74.3%) underwent endoscopic transnasal Draf Ⅱa-Ⅲ frontal sinusotomy, and 9 cases (25.7%) underwent endoscopic transnasal Darf Ⅱb-Ⅲ frontal sinusotomy combined with frontal trephination. The average follow-up time was (84.72±57.42) months. The success rate of one-time endoscopic repair was 97.1% (34/35). One patient required a second procedure, resulting in an overall success rate of 100%. Thirty-three patients had a widely patent frontal sinus ostium postoperatively, while two experienced stenosis. Conclusions:Endoscopic surgery is effective for treating frontal meningoencephalocele and CSF leaks while preserving frontal sinus drainage. Combined frontal trephination is recommended for defects that are difficult to repair using the conventional transnasal approach.

After being routinely cultured for 48 h (similarly hereinafter), cells in pH 7.4+ 6 h, pH 7.0+ 6 h, pH 6.5+ 6 h, and pH 6.0+ 6 h groups were cultured with pH 7.4, pH 7.0, pH 6.5, and pH 6.0 DMEM-F12 medium (similarly hereinafter), respectively, and then they were cultured for 6 h. Cells in pH 6.5+ 1 h and pH 6.5+ 3 h groups were cultured with pH 6.5 medium, and then they were cultured for 1 h and 3 h, respectively. Viability of cells was detected by methyl-thiazolyl-tetrazolium (MTT) method. (2) The primary cardiomyocytes were divided into pH 7.4, pH 6.5, and pH 6.5+ taxol groups according to the random number table, with 2 wells in each group. Cells in pH 7.4 group were cultured with pH 7.4 medium, while cells in pH 6.5 and pH 6.5+ taxol groups were cultured with pH 6.5 medium. Cells in pH 6.5+ taxol group were added with taxol of a final molarity of 0.2 μmol/L in addition, and then they were cultured for 6 h. Morphology and density of microtubule of cells was detected by immunofluorescence assay. (3) The primary cardiomyocytes were grouped and treated as in experiment (2), with 2 wells in each group. The expressions of polymerized microtubulin and free microtubulin were determined with Western blotting. (4) The primary cardiomyocytes were grouped and treated as in experiment (2), with 4 wells in each group. Viability of cells after treated with taxol was detected by MTT method.

(2) Microtubules of cells in pH 7.4 group were radially distributed around the nucleus with clear tubular structure. Compared with that in pH 7.4 group, the skeleton of microtubules of cells in pH 6.5 group was obviously damaged, with broken structure of microtubule and reduced density. Compared with that in pH 6.5 group, the damage degree of microtubules of cells in pH 6.5+ taxol group was obviously alleviated, and the structure of microtubules basically returned to normal. (3) Compared with that in pH 7.4 group, the expression of free microtubulin of cells in pH 6.5 group was significantly increased (t=3.030, P<0.05), while the expression of polymerized microtubulin of cells was significantly decreased (t=8.604, P<0.05). Compared with that in pH 6.5 group, the expression of free microtubulin of cells in pH 6.5+ taxol group was significantly decreased (t=4.559, P<0.05), while the expression of polymerized microtubulin of cells was significantly increased (t=5.472, P<0.05). (4) Viability of cells in pH 7.4, pH 6.5, and pH 6.5+ taxol groups were 1.00±0.10, 0.83±0.04, and 0.93±0.10, respectively. Compared with that in pH 7.4 group, the viability of cells in pH 6.5 group was obviously declined (t=4.412, P<0.05). Compared with that in pH 6.5 group, the viability of cells in pH 6.5+ taxol group was obviously increased (t=2.461, P<0.05). Conclusions The decline of pH value reduces the viability of cardiomyocytes of rats through destroying the skeleton of microtubule. Stabilizing microtubule skeleton can significantly reduce acidic treatment-induced damage and ameliorate cardiomyocyte viability.

Objective To investigate influence of nicotinic acid adenine dinucleotide phosphate (NAADP) on autophagy in hypoxic cardiomyocytes of rats and its mechanism.Methods Five neonatal Sprague-Dawley rats were collected and sacrificed to harvest the hearts,and primary cardiomyocytes were separated for the following experiments.(1) Primary cardiomyocytes were collected and divided into normoxia group,hypoxia 9 h group,and hypoxia 9 h + NAADP group according to random number table,with 5 wells in each group.Cells in normoxia group were cultured routinely in the constant temperature incubator at 37 ℃ for 9 hours.Cells in hypoxia 9 h group and hypoxia 9 h + NAADP group were cultured in hypoxic incubator with volume fraction 94％ nitrogen,5％ carbon dioxide,and 1％ oxygen for 9 hours.Before hypoxia,cells in hypoxia 9 h + NAADP group were dealt with final amount-of-substance concentration 10 μmol/L NAADP.Cell counting kit 8 was used to measure cell viability.(2) Primary cardiomyocytes were collected and divided into normoxia group,hypoxia 9 h group,hypoxia 9 h + NAADP group,hypoxia 9 h + tran-Ned-19 group,and hypoxia 9 h + trans-Ned-19 + NAADP group according to the random number table,with 2 wells in each group.Cells in normoxia group were cultured routinely in the constant temperature incubator at 37 ℃ for 9 hours.And cells in the other 4 groups were cultured in hypoxic incubator as that in experiment (1) Before hypoxia,cells in hypoxia 9 h + NAADP group were dealt with amount-of-substance concentration 10 μmol/L NAADP,cells in hypoxia 9 h + tran-Ned-19 group were dealt with amount-of-substance concentration 1 μmol/L trans-Ned-19,and cells in hypoxia 9 h + trans-Ned-19 + NAADP group were dealt with amount-of-substance concentration 10 μmol/L NAADP and 1 μmol/L trans-Ned-19.Protein expressions of microtubule associated protein 1 light chain 3-Ⅱ and P62 were detected by Western blotting.(3) Primary cardiomyocytes were collected and grouped as those in experiment (1).The lysosomal acidity was determined by immunofluorescence method.Data were processed with one-way analysis of variance and least-significant difference test.Results (1) The cell viability in normoxia group was 1.114 ± 0.024,which was significantly higher than 0.685 ± 0.079 of cells in hypoxia 9 h group (P ＜ 0.01).The cell viability of hypoxia 9 h + NAADP group was 0.886 ± 0.061,which was obviously higher than that of cells in hypoxia 9 h group (P ＜0.05).(2) Expressions of microtubule-associated protein 1 light chain 3-Ⅱ and P62 of cells in hypoxia 9 h group were significantly higher than those of cells in normoxia group (P ＜ 0.0l).Compared with those in hypoxia 9 h group,expression of P62 in hypoxia 9 h + NAADP group was significantly decreased (P ＜ 0.01),while expression of microtubule-associated protein 1 light chain 3-Ⅱ did not change significantly (P ＞ 0.05).There were no significantly statistical difference in expressions of microtubule-associated protein 1 light chain 3-Ⅱ and P62 between hypoxia 9 h group and hypoxia 9 h + trans-Ned-19 group (P ＞ 0.05).Compared with those of cells in hypoxia 9 h + NAADP group,expression of P62 of cells in hypoxia 9 h + trans-Ned-19 + NAADP group was obviously increased (P ＜ 0.01),while expression of microtubule-associated protein 1 light chain 3-Ⅱ did not change significantly (P ＞ 0.05).(3) The intensity of green fluorescence of cells in normoxia group was strong and co-localized well with red fluorescence,and internal environment of lysosome was with stronger acidity.The intensity of green fluorescence in cells of hypoxia 9 h group was significantly lower than that of cells in normoxia group,and acidity of internal environment of lysosome was weakened.The intensity of green fluorescence and acidity of internal environment of lysosome in hypoxia 9 h + NAADP were significantly stronger than those of cells in hypoxia 9 h group,but significantly lower than those of cells in normoxia group.Conclusions NAADP can improve myocardial cell viability through acidifying internal environment of lysosome of cardiomyocyte after hypoxia,promoting degradation of autophagosomes,reducing autophagic lysosomal accumulation,and repairing damaged autophagie flow.

Objective To evaluate the clinical significance of bone marrow minimal residual disease (MRD) monitoring by multi-parameter flow cytometry (FCM) regularly after the first complete remission (CR1) in patients with acute myeloid leukemia (AML).Methods A total of 63 paitents with AML who had got CR1 after chemotherapy were regularly monitored for MRD in bone marrow by FCM,and MRD ≥ 10-4 was positive.According to the latest standards of National Comprehensive Cancer Network (NCCN) for disease risks,they were categorized into three groups:better risk group (20 cases),intermediate risk group (27 cases) and poor risk group (16 cases).The probability of continuous complete remission (CCR) was calculated by KaplanMeier formula,and the statistical difference between MRD positivc and MRD negative CCR probabilities was evaluated by log-rank test.Results The positive rates of MRD were 20％(4/20),30％(8/27) and 10/16 in better risk group,intermediate risk group and poor risk group respectively.The difference between better risk group and intermediate risk group had no statistical significance (P=0.454),and the difference between poor risk group and intermediate risk group had statistical significance (P =0.035).Twenty-two cases showed positive MRD,and 41 cases showed negative MRD.The probability of CCR at 24 and 36 months in MRD positive patients were 18％ (4/22),18％ (4/22),in MRD negative patients were 83％ (34/41),80％ (33/41),and there were significant differences (P ＜ 0.01).Conclusions The dynamic detection of MRD by FCM can be used to evaluate the therapeutic effect and prognosis of AML.MRD monitoring has important clinical significance and can help to adjust the intensity of chemotherapy,carry out individualized treatment,predict prognosis,and choose appropriate therapy.
