Objective:To investigate the efficacy of blepharoplasty using the "double-line technique" in addressing upper eyelid skin laxity in middle-aged and elderly patients.Methods:A retrospective analysis was conducted on the clinical data of middle-aged and elderly patients with moderate to severe upper eyelid skin laxity who were admitted to the Plastic Surgery Department of Shaanxi Provincial People’s Hospital between January 2020 and January 2023. The same surgeon performed the "double-line" blepharoplasty to excise excess upper eyelid skin for laxity correction. Patients were positioned flat with their eyes closed; an arcuate line a (5-7 mm above the pupil) and a second line b (aligned with the eyelid margin in an upright position) were marked. The skin between these two lines was excised. Postoperatively, the double eyelid shape, improvement in skin laxity, adverse reactions, and patient satisfaction (categorized as satisfied, basically satisfied, unsatisfied) were assessed.Results:A total of 145 patients were included in the study, comprising 27 males and 118 females. Their ages ranged from 38 to 78 years, with an average age of 52 years. All patients’ incisions healed primarily without complications such as hematoma and infection. During the 3 to 12 months of follow-up after surgery, the double eyelid arcs on both sides appeared symmetrical and natural. The upper eyelid laxity was effectively corrected, obscured vision was improved, crow’s feet were reduced, and the periorbital area was rejuvenated. Patient satisfaction with the surgical results was high, with 112 patients reporting satisfaction, 25 reporting basically satisfied, and 8 reporting dissatisfaction. The overall satisfaction rate reached 94.48%(137/145). Among those dissatisfied, 6 cases cited the double eyelid crease as being too narrow, and 2 cases noted asymmetry in the double eyelid crease.Conclusion:The "double-line method" for blepharoplasty is straightforward to perform and effectively removes excess upper eyelid skin. It is suitable for middle-aged and elderly patients with moderate to severe upper eyelid skin laxity, resulting in favorable surgical outcomes.

Objective:To explore the impacts of thermotherapy combined with gemcitabine on the biological behavior of tongue squamous cell carcinoma cells.Methods:Human tongue squamous cell carcinoma Tca8113 cells were divided into the control group (blank control), gemcitabine group, thermotherapy group (heated in an incubator at 43℃ for 1 h and then incubated at 37℃ for 24 h) and thermotherapy + gemcitabine group. The proliferation ability of Tca8113 cells was assessed by EdU staining and CCK-8 assay. Cell apoptosis and cell cycle of Tca8113 cells were detected by flow cytometry. The invasion of Tca8113 cells was determined by Transwell chamber assay. The expression levels of cyclin D1 (CyclinD1), Bcl-2-associated X protein (Bax), matrix metalloproteinase (MMP)-9, phosphorylated histone H2AX (γH2AX) and Nijmegen breakage syndrome 1 (NBS1) proteins in Tca8113 cells were measured by Western blot. The changes of tumor mass and volume were detected by xenograft tumor in vivo test in nude mice. Multi-group comparison was performed by one-way ANOVA. Two group comparison was conducted by SNK- q test. Results:Compared with the control group, EdU positive cell percentage, OD 450 value, invasive cell number, CyclinD1, MMP-9 and NBS1 protein expression of Tca8113 cells were decreased, whereas the apoptosis rate, the expression of Bax and γH2AX proteins were increased in the gemcitabine, thermotherapy and thermotherapy + gemcitabine groups ( q=4.45-72.06, all P<0.001). Compared with the control group, the proportion of G 0/G 1 phase cells was decreased, whereas the proportion of S and G 2/M phase cells was increased in the gemcitabine and thermotherapy + gemcitabine groups, the proportion of G 0/G 1 phase cells was decreased and the proportion of G 2/M phase cells was increased in the hyperthermia group ( q=10.36-61.09, all P<0.001). Compared with the gemcitabine and thermotherapy groups, EdU positive cell percentage, OD 450 value, G 0/G 1 phase cell proportion, invasive cell number, CyclinD1, MMP-9 and NBS1 protein expression of Tca8113 cells were decreased, whereas apoptosis rate, S, G 2/M phase cell proportion, Bax and γH2AX protein expression were increased in the thermotherapy + gemcitabine group ( q=4.45-28.73, all P<0.001). Xenograft tumor in vivo test in nude mice showed that the tumor volume and mass of nude mice in the gemcitabine, thermotherapy, and thermotherapy + gemcitabine groups were decreased compared with those in the control group ( q=5.58-73.02, all P<0.001). Compared with the gemcitabine and thermotherapy groups, the tumor volume and mass in the thermotherapy + gemcitabine group were decreased ( q=5.58-21.45, all P<0.001). Conclusion:The combination of thermotherapy and gemcitabine can inhibit the proliferation and invasion, block the cell cycle, and induce cell apoptosis of Tca8113 cells.

Objective To investigate the impacts of cinobufotalin combined with docetaxel+cisplatin chemotherapy on the disease control and the level of vascular endothelial growth factor(VEGF)in serum of patients with non-small cell lung cancer.Methods Totally 70 patients with non-small cell lung cancer admitted to Zhejiang Veteran Hospital from March 2019 to March 2022 were included.They were randomly divided into combination group(cinobufotalin combined with docetaxel+cisplatin,n= 35)and control group(docetaxel+cisplatin chemotherapy alone,n=35).The disease control rates of two groups,serum VEGF level,carcinoembryonic antigen(CEA),cy-tokeratin 19(CK19)and carbohydrate antigen 125(CA125)were measured using ELISA;life quality of patients was evaluated with the KPS score;The adverse events between two groups were compared.Results The disease control rate in the combination group(33/35,94.29％)was higher than that that of control group(25/35,71.43％,)(P＜0.05).After treatment,the level of VEGF in both groups of patients decreased,and the KPS score increased(P＜0.05)especially in the combination group(P＜0.05).After treatment,the level of serum CEA,CA125,and CK19 of control group and combination group were obviously lower than those before treatment(P＜0.05),while those in the combination group were even lower(P＜0.05).The incidence of adverse events in the combination group(5/35,14.29％)was lower than that in the control group(13/35,37.14％)(P＜0.05).Conclusions Cinobufotalin combined with docetaxel+cisplatin chemotherapy as a potential new chemotherapy significantly reduces the level of VEGF and tumor biomarkers in serum factor,improves the life quality of patients.The combined therapy is proved tobe safe.

Objective:To investigate the regulation and possible mechanism of hyperthermia (HT) on the ferroptosis of squamous cell carcinoma of the tongue cell line CAL-27.Methods:Half maximal inhibitory concentration (IC 50) of Fer-1, an inhibitor of ferroptosis, was detected by CCK-8 assay and used for subsequent experiments. CAL-27 cells were divided into the HT, control, Fer-1 and HT+ Fer-1 groups according to experimental design. Reactive oxygen species (ROS) levels and iron ion concentration were determined by corresponding detection kits. The p53 and TfR1 mRNA levels were detected by real-time reverse transcription PCR. Cell migration was detected by cell scratch test and cell apoptosis was detected by flow cytometry. Results:HT significantly up-regulated the ROS levels ( P<0.01) and iron ion concentration ( P<0.001), and significantly increased the expression levels of p53 and TfR1 mRNA (both P<0.01). The cell migration ability was decreased ( P<0.001), whereas cell apoptosis rate was increased by HT ( P<0.01). In the HT+Fer-1 group, the ROS levels ( P<0.001), iron ion concentration ( P<0.001), expression levels of p53 and TfR1 mRNA (both P<0.01) were significantly down-regulated, the cell migration ability was recovered ( P<0.01), and cell apoptosis rate was decreased ( P<0.01) compared with those in the HT group, respectively. Conclusions:HT may induce the ferroptosis of CAL-27 cell line, inhibit cell migration ability and promote cell apoptosis by activating the p53/TfR1 pathway.

OBJECTIVE: This study aimed to investigate the expression and clinical significance of proline-rich tyrosine kinase 2 (Pyk2) and phospho-protein kinase B (p-AKT) in tongue squamous cell carcinoma (TSCC) and adjacent nontumor tissues. METHODS: The Pyk2 and p-AKT protein levels were detected via immunohistochemistry in 45 cases of TSCC tissues and 30 cases of adjacent nontumor tissues. The relationships of the two protein levels and clinicopathological characteristics were also analyzed. RESULTS: Pyk2 and p-AKT levels were significantly higher in the TSCC tissues than in the adjacent nontumor tissues (P<0.05). Nontumor tissues showed poor or no expression. The expression levels of the two proteins were positively correlated (γs=0.412). The expression of Pyk2 was associated with histopathological differentiation type, regional lymph node metastasis, and TNM staging (P<0.05), but not with age and gender. The expression of p-AKT was only related to histopathological differentiation types (P<0.05). CONCLUSIONS The abnormal expression of Pyk2 and p-AKT proteins might be closely related to the development and progression of TSCC. Joint detection can be used as an indicator to estimate the degree of TSCC.

Objective: To analyze the recent postoperative and long-term postoperative complications of open-splenectomy and disconnection in patients with portal hypertension. Methods: There were 1 118 cases with portal hypertension who underwent open splenectomy and azygoportal disconnection from April 2010 to September 2015 at Department of Surgery, People′s Liberation Army 302 Hospital. Retrospective case investigation and telephone follow-up were conducted in October 2016. All patients had history of upper gastrointestinal bleeding before operation. Short-term complications after surgery were recorded including secondary laparotomy of postoperative abdominal hemostasis, severe infection, intake disorders, liver insufficiency, postoperative portal vein thrombosis and perioperative mortality. Long-term data including postoperative upper gastrointestinal rebleeding, postoperative survival rate and incidence of postoperative malignancy were recorded, too. GraphPad Prism 5 software for data survival analysis and charting. Results: Postoperative short-term complications in 1 118 patients included secondary laparotomy of postoperative abdominal hemostasis(1.8%, 21/1 118), severe infection(2.9%, 32/1 118), intake disorders(1.0%, 11/1 118), liver dysfunction (1.6%, 18/1 118), postoperative portal vein thrombosis(47.1%, 526/1 118)and perioperative mortality(0.5%, 5/1 118). After phone call following-up, 942 patients′ long-term data were completed including 1, 3, 5 years postoperative upper gastrointestinal rebleeding rate(4.4%, 12.1%, 17.2%), 1, 3, 5-year postoperative survival rate(97.0%, 93.5%, 90.3%); the incidence of postoperative malignant tumors in 1, 3 and 5 years were 1.7%, 4.4% and 6.2%. Conclusions Reasonable choosing of surgical indications and timing, proper performing the surgery process, effective conducting perioperative management of portal hypertension are directly related to the patient′s short-term prognosis after portal hypertension. Surgical intervention can reduce the rates of patients with upper gastrointestinal rebleeding, improve survival, and do not increase the incidence of malignant tumors.
