Objective·To observe the effects of gingipain extract on the biological characteristics of oral squamous cell carcinoma cell HN6.Methods·The HN6 cell line was selected,cultivated,and divided into different groups based on the protein concentration of gingipain extract from Porphyromonas gingivalis:control group,3.125 μg/mL group,6.25 μg/mL group,12.5 μg/mL group,25 μg/mL group,50 μg/mL group,and 100 μg/mL group.After 24 and 48 h of cultivation,CCK-8 assay was used to detect the effects of gingipain extract on HN6 cell proliferation activity.Subsequent experiments were divided into control group,25 μg/mL group and 50 μg/mL group.Flow cytometry was used to examine the effects of gingipain extract on cell cycle.Scratch assay and Transwell assay were performed to evaluate cell migration and invasion ability.Real-time PCR(RT-PCR)and Western blotting were used to measure the expression of E-cadherin and N-cadherin proteins and genes in cells.Results·Stimulated with gingipain extract for 24 h,the HN6 cells showed significantly increased proliferation activity in the 25 μg/mL(P=0.025),50 μg/mL(P=0.000),and 100 μg/mL(P=0.049)groups compared to the control group.After 48 h,proliferation activity was significantly higher in the 6.25 μg/mL(P=0.024),12.5 μg/mL(P=0.006),25 μg/mL(P=0.000),50 μg/mL(P=0.000),and 100 μg/mL(P=0.000)groups compared to the control group.Cell cycle analysis revealed that,after 24 h of gingipain stimulation,the proportion of HN6 cells in the G1 phase decreased,while the proportion in the S+G2 phase significantly increased compared to the control group(25 μg/mL group:P=0.024;50 μg/mL group:P=0.001).Compared to the control group,the scratch assay demonstrated a significant increase in the percentage of scratch closure as the concentration of gingipain extract increased(P=0.001).Compared to the control group,the Transwell invasion assay showed a significant increase in the number of cells passing through the bottom of the chamber as the concentration of gingipain extract increased.RT-PCR and Western blotting results indicated that as the concentration of gingipain extract increased,the expression levels of N-cadherin mRNA and protein in HN6 cells significantly increased,while the expression levels of E-cadherin mRNA and protein significantly decreased compared to the control group.Conclusion·Gingipain extract could promote proliferation,migration,and invasion of oral squamous cell carcinoma HN6 cells.

Objective To explore the efficacy and safety of perforator flap eyelid reconstruction surgery for eyelid repair and reconstruction in patients with eyelid tumors after surgery.Methods Totally 80 patients(80 eyes)who re-ceived eyelid tumor surgery and planned to undergo the perforator flap eyelid reconstruction surgery in our hospital from January 2012 to December 2022 were included.All of them have early-stage and mid-stage eyelid tumors with no orbital or systemic metastasis.A perforator flap eyelid reconstruction surgery was conducted to treat the eyelid defects.The differ-ence in height and length of the palpebral fissure,aesthetic function scores and levels of depression and anxiety of patients before and after repair were compared;the clinical efficacy,adverse reactions and prognosis of patients were evaluated.Results Among the 80 eyes,there were 35 eyes with significant effect,35 eyes with effective impact,and 10 eyes with no effect,with a total effective rate of 87.5％.The height and length of palpebral fissure of patients after repair were(1.49±0.47)mm and(1.43±0.55)mm,respectively,which were significantly lower than those before repair[(2.55± 0.35)mm and(2.38±0.49)mm](both P＜0.01).The aesthetic function score before repair was 0.91±0.23,and that after repair was 1.87±0.19,with a significant difference(P＜0.01).The scores of the Self-rating Anxiety Scale and Self-rating Depression Scale after repair were 40.14±6.54 and 39.45±7.65,respectively,which were significantly lower than those before repair(59.56±8.23 and 57.93±8.19)(both P＜0.01).Among the 80 patients,the total incidence of compli-cations was 27.5％(22/80).All patients were followed up for 6-36 months,with an average follow-up time of(12.39± 6.17)months.No tumor recurrence was found during the follow-up.All composite flaps survived without infection,necro-sis or displacement.Conclusion The perforator flap eyelid reconstruction surgery has a good and safe therapeutic effect on repairing full-layer eyelid defects in patients who underwent eyelid tumor surgery.

Objective:To explore the application of C-reactive protein(CRP) to prealbumin (PA) ratio(CRP/PA) for diagnosis and prognosis evaluation of sepsis.Methods:By a retrospective study, a total of 95 sepsis patients (sepsis group) and 100 local infection patients(non-sepsis group) treated in Dongying People′s Hospital from September 2021 to September 2022 were enrolled. Sepsis patients were divided into survival group(57 cases) and death group (38 cases) according to the 28-day outcome. The clinical data were collected and CRP/PA was calculated. Multivariate Logistic regression and Cox regression were used to analyze the relationship between various indicators and the occurrence and prognosis of sepsis, and receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic and prognostic value of CRP/PA for sepsis. Kaplan-Meier survival analysis was used to evaluate the prognostic value of different CRP/PA ratios for patients with sepsis.Results:The systolic blood pressure, diastolic blood pressure, prealbumin were lower and heart rate, respiratory rate, CRP, CRP/PA, procalcitonin were higher in the sepsis group compared to the non-sepsis group: (117.27 ± 11.65) mmHg (1 mmHg = 0.133 kPa) vs. (123.26 ± 10.71) mmHg, (69.42 ± 8.58) mmHg vs. (75.44 ± 6.53) mmHg, (174.09 ± 24.77) g/L vs. (207.13 ± 34.31) g/L, (97.87 ± 12.73) bpm vs. (86.90 ± 10.19) bpm, 22.0(20.00, 25.00) times/min vs. 21.00(19.00, 23.00) times/min, (93.96 ± 19.64) mg/L vs. (77.56 ± 22.54) mg/L, 0.54(0.44, 0.65) vs. 0.37(0.28, 0.46), 3.35(2.16, 4.17) μg/L vs. 1.52(0.81, 2.16) μg/L, there were statistical differences ( P<0.05). Multivariate Logistic regression analysis showed that CRP/PA and procalcitonin were risk factors for sepsis ( P<0.05). The results of ROC curve showed that the area under the curve (AUC) of CRP/PA in diagnosis of sepsis was 0.821, the specificity and sensitivity was 76.0% and 93.7%, respectively. The diastolic blood pressure, prealbumin, neutrophil were higher and the heart rate, respiratory rate, CRP, CRP/PA, lymphocytes, procalcitonin were lower in the survival group compared to the death group: (71.76 ± 8.86) mmHg vs. (67.86 ± 8.10) mmHg, (181.46 ± 24.35) g/L vs. (163.05 ± 21.28) g/L, (63.46 ± 9.88) × 10 9/L vs.(57.13 ± 8.64) × 10 9/L, (95.68 ± 13.48) times/min vs. (101.16 ± 10.88) times/min, 22.00(19.50, 24.00) times/min vs. 24.00(20.00, 28.00) times/min, (88.09 ± 19.35) mg/L vs. (102.76 ± 16.75) mg/L, 0.46(0.41, 0.58) vs. 0.63(0.55, 0.72), 21.00(16.00, 30.00) ×10 9/L vs. 29.50(18.00, 37.30) ×10 9/L, 2.94(2.10, 3.97) μg/L vs. 3.82(2.21, 4.77) μg/L, there were statistical differences ( P<0.05). Multivariate Cox regression analysis showed that CRP/PA and procalcitonin were independent risk factors for the prognosis of sepsis ( P<0.05). The AUC of CRP/PA in predicting the prognosis of sepsis was 0.827, the specificity and sensitivity was 92.1% and 63.8%, respectively. Grouped by the cut-off of CRP/PA (0.48), the 28-day mortality rate of patients in the CRP/PA>0.48 was significantly higher than that of patients in the CRP/PA≤0.48, there was statistical difference ( P<0.01). Conclusions:CRP/PA ratio can be used as an index for diagnosis and prognosis evaluation of sepsis.

Objective:To summarize and analyze the diagnostic and therapeutic characteristics of asymptomatic primary hyperparathyroidism (aPHPT).Methods:A retrospective analysis was conducted on the clinical data of 103 patients with aPHPT admitted to the Chinese PLA General Hospital from January 2012 to September 2023. The clinical characteristics, treatment modes, and prognoses of the patients were analyzed. GraphPad Prism 8.0 software was used for statistical analysis.Results:Among the 103 cases, there were 37 males and 66 females, aged from 25 to 78 years, with an average age of (53.81±11.34) years. Ninety-eight cases (95.15%) visited due to abnormal findings during physical examination and 5 cases (4.85%) due to hypertension, diabetes or other diseases. All patients underwent minimally invasive parathyroidectomy with small incision, with 96 cases (93.20%) pathologically diagnosed as adenomas and 7 cases as hyperplasia (6.80%). Postoperative mean serum calcium, parathyroid hormone (PTH) and alkaline phosphatase (ALP) levels were respectively significantly lower than preoperative levels, while postoperative serum phosphorus level was significantly higher than preoperative level ( P<0.05). The mean lesion volume was (3.32±6.72)cm 3 (range 0.05-49.50 cm 3). Patients with different lesion volumes had significant differences in preoperative serum calcium, PTH and ALP levels. Lesion volume was positively correlated to preoperative serum calcium(ρ=0.36, P<0.01), PTH(ρ=0.50, P<0.01) and ALP(ρ=0.39, P<0.01). Among 103 patients, 94 cases were followed up (91.26%), 9 cases were lost (8.74%), and the mean follow-up period was (60.15±29.23) months. The followed-up patients were alive and had no recurrence of lesions or complications, and their blood calcium levels were normal. Conclusion:aPHPT can be preliminarily diagnosed through blood biochemistry and imaging examination, and minimally invasive surgery can offer good prognosis without serious complications.

Objective To observe the value of 18F-FDG PET/CT semi-quantitative parameters for predicting spread through air spaces(STAS)of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.Methods Data of 85 patients with clinical stage Ⅰa—Ⅲ a lung adenocarcinoma who underwent preoperative 18F-FDG PET/CT were retrospectively analyzed.The patients were divided into positive group(n=23)or negative group(n=62)according to whether pathology showed STAS or not.Clinical and PET/CT data were compared between groups,and logistic analysis was performed to explore the efficacy of each parameter for predicting STAS.Results Significant differences of gender,carcinoma embryonic antigen,clinical stage,pathological grade,micropapillary growth and proportion were found between groups(all P＜0.05).The maximum,the mean,the peak standard uptake value(SUVmax,SUVmean,SUVpeak),as well as the maximum,the mean and the peak standard uptake value normalized by lean body mass(SULmax,SULmean,SULpeak),also the total lesion glycolysis(TLG)in positive group were all significantly higher than those in negative group(all P＜0.05).Patients'gender,proportion of micropapillary growth,SUVmax and SULmax were all independent risk factors of STAS of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.The area under the curve(AUC)of the above parameters for predicting STAS was 0.666,0.912,0.839 and 0.842,respectively,and of the combination was 0.957.Conclusion 18 F-FDG PET/CT semi-quantitative parameters SUVmax and SULmax were helpful for predicting STAS of clinical stage Ⅰa—Ⅲ a lung adenocarcinoma,and further combination of gender and proportion of micropapillary growth could improve diagnostic efficacy.

Thyroid associated ophthalmopathy (TAO) is an organ-specific autoimmune disease. TAO is clinically classified into active and inactive stage, and the accurate judgment is the key point of treatment choice. Clinical activity score (CAS) is often used for the assessment of TAO activity, which is subjective to some extent. With the development of imaging techniques, ultrasonography, CT, MRI and radionuclide imaging have gradually been applied into the diagnosis and treatment of TAO. What′s more, the imaging is an important complement to CAS from the aspects of anatomical and functional metabolism, which can better assess the activity and the therapy response of TAO. The clinical value of medical imaging in activity and treatment efficacy evaluation of TAO is reviewed in this article.

OBJECTIVE: To investigate the surgical technique and effectiveness of titanium elastic nail (TEN) assisted retrograde channel screw implantation of superior pubic branch. METHODS: The clinical data of 31 patients with pelvic or acetabular fractures treated with retrograde channel screw implantation in superior pubic branch between January 2021 and April 2022 were retrospectively analyzed. Among them, 16 cases were implanted with assistance of TEN (study group) and 15 cases were implanted under the guidance of C-arm X-ray machine (control group). There was no significant difference in gender, age, cause of injury, Tile classification of pelvic fracture, Judet-Letournal classification of acetabular fracture, and time from injury to operation between the two groups ( P>0.05). The operation time, fluoroscopy times, and intraoperative blood loss of each superior pubic branch retrograde channel screw were recorded during operation. X-ray films and three-dimensional CT were reexamined after operation, the quality of fracture reduction was evaluated by Matta score standard, and the position of channel screw was evaluated by screw position classification standard. The fracture healing time was recorded during the follow-up, and the postoperative functional recovery was evaluated by Merle D'Aubigne Postel score system at last follow-up. RESULTS: Nineteen and 20 retrograde channel screws of superior pubic branch were implanted in the study group and the control group, respectively. The operation time, fluoroscopy times, and intraoperative blood loss of each screw in the study group were significantly less than those in the control group ( P<0.05). According to the postoperative X-ray films and three-dimensional CT, none of the 19 screws in the study group penetrated out of the cortical bone or into the joint, and the excellent and good rate was 100% (19/19); in the control group, there were 4 screws of cortical bone penetration, and the excellent and good rate was 80% (16/20); the difference between the two groups was significant ( P<0.05). Matta score standard was used to evaluate the quality of fracture reduction, there was no patient in the two groups with poor reduction results, and the difference was not significant between the two groups ( P>0.05). The incisions of the two groups healed by first intention, and there was no complication such as incision infection, skin margin necrosis, and deep infection. All patients were followed up 8-22 months, with an average of 14.7 months. There was no significant difference in healing time between the two groups ( P>0.05). At last follow-up, the difference in functional recovery evaluated by the Merle D'Aubigne Postel scoring system between the two groups was not significant ( P>0.05). CONCLUSION TEN assisted implantation technique can significantly shorten the operation time of retrograde channel screw implantation of superior pubic branch, reduce the times of fluoroscopy, and have less intraoperative blood loss and accurate screw implantation, which provides a new safe and reliable method for minimally invasive treatment of pelvic and acetabular fractures.

Purpose: The human epidermal growth factor receptor 2 (HER2) is an established therapeutic target for various kinds of solid tumors. HER2 amplification occurs in approximately 1% to 6% of colorectal cancer. In this study, we aimed to assess the efficacy and safety of trastuzumab in combination with chemotherapy in HER2-positive metastatic colorectal cancer (mCRC). Materials and Methods: An open-label, phase II trial (Clinicaltrials.gov: NCT03185988) was designed to evaluate the antitumor activity of trastuzumab and chemotherapy in HER2-positive digestive cancers excluding gastric cancer in 2017. Patients from this trial with HER2-positive, KRAS/BRAF wild-type, unresectable mCRC were analyzed in this manuscript. Eligible patients were treated with trastuzumab (8 mg/kg loading dose and then 6 mg/kg every 3 weeks) and irinotecan (120 mg/m2 days 1 and 8 every 3 weeks). The primary endpoint was the objective response rate. Results: Twenty-one HER2-positive mCRC patients were enrolled in this study. Seven patients (33.3%) achieved an objective res-ponse, and 11 patients (52.4%) had stable disease as their best response. The median progression-free survival (PFS) was 4.3 months (95% confidence interval, 2.7 to 5.9). Four of the 21 patients (19.0%) had grade 3 adverse events, including leukopenia, neutropenia, urinary tract infection, and diarrhea. No treatment-related death was reported. Exploratory analyses revealed that high tumor tissue HER2 copy number was associated with better therapeutic response and PFS. Alterations in the mitogen-activated protein kinase pathway, HER2 gene, phosphoinositide 3-kinase/AKT pathway, and cell cycle control genes were potential drivers of trastuzumab resistance in mCRC. Conclusion Trastuzumab combined with chemotherapy is a potentially effective and well-tolerated therapeutic regimen in mCRC with a high HER2 copy number.
