BACKGROUND One of the main characteristics of oral squamous cell carcinoma(OSCC)is that it metastasizes to cervical lymph nodes frequently with a high degree of local invasiveness.A primary feature of malignant tumors is their penetration of neighboring tissues,such as lymphatic and blood arteries,due to the tumor cells'capacity to break down the extracellular matrix(ECM).Matrix metalloproteinases(MMPs)constitute a family of proteolytic enzymes that facilitate tissue remodeling and the degradation of the ***-9 and MMP-13 belong to the group of extracellular matrix degrading enzymes and their expression has been studied in OSCC because of their specific ***-13,a collagenase family member,is thought to play an essential role in the MMP activation cascade by breaking down the fibrillar collagens,whereas MMP-9 is thought to accelerate the growth of *** MMP-13 expression has been associated with tumor behavior and patient prognosis in a number of malignant *** To assess the immunohistochemical expression of MMP-9 and MMP-13 in *** A total of 40 cases with histologically confirmed OSCC by incisional biopsy were included in this cross-sectional retrospective *** protocols for both MMP-9 and MMP-13 immunohistochemical staining were performed according to the manufacturer’s recommendations along with the normal gingival epithelium as a positive *** the observations were recorded and Pearson’sχ²test with Fisher exact test was used for statistical *** Our study showed no significant correlation between MMP-9 and MMP-13 staining intensity and tumor *** majority of the patients were in advanced TNM stages(III and IV),and showed intense expression of MMP-9 and *** The present study suggests that both MMP-9 and MMP-13 play an important and independent role in OSCC progression and *** expression of MMP-9 and MMP-13,irrespective of histological grade of OSCC,correlates well with T

Peripheral nerve injuries induce a severe motor and sensory deficit. Since the availability of autologous nerve transplants for nerve repair is very limited, alternative treatment strategies are sought, including the use of tubular nerve guidance conduits(tNGCs). However, the use of tNGCs results in poor functional recovery and central necrosis of the regenerating tissue, which limits their application to short nerve lesion defects(typically shorter than 3 cm). Given the importance of vascularization in nerve regeneration, we hypothesized that enabling the growth of blood vessels from the surrounding tissue into the regenerating nerve within the tNGC would help eliminate necrotic processes and lead to improved regeneration. In this study, we reported the application of macroscopic holes into the tubular walls of silk-based tNGCs and compared the various features of these improved silk^(+) tNGCs with the tubes without holes(silk^(–) tNGCs) and autologous nerve transplants in an 8-mm sciatic nerve defect in rats. Using a combination of micro-computed tomography and histological analyses, we were able to prove that the use of silk^(+) tNGCs induced the growth of blood vessels from the adjacent tissue to the intraluminal neovascular formation. A significantly higher number of blood vessels in the silk^(+) group was found compared with autologous nerve transplants and silk^(–), accompanied by improved axon regeneration at the distal coaptation point compared with the silk^(–) tNGCs at 7 weeks postoperatively. In the 15-mm(critical size) sciatic nerve defect model, we again observed a distinct ingrowth of blood vessels through the tubular walls of silk^(+) tNGCs, but without improved functional recovery at 12 weeks postoperatively. Our data proves that macroporous tNGCs increase the vascular supply of regenerating nerves and facilitate improved axonal regeneration in a short-defect model but not in a critical-size defect model. This study suggests that further optimizatio

OBJECTIVE: To examine the effect of electroacupuncture(EA) application on postoperative pain levels and the amount of analgesic use in patients who underwent periodontal flap surgery. METHODS: In this prospective, randomized and controlled study, patients planned for periodontal surgery were divided into two groups [EA group(n = 22): patients who received electroacupuncture and control group(n = 22): patients who did not receive electroacupuncture]. Electroacupuncture was applied bilaterally to the Hegu(LI4), Daying(ST5), and Jiache(ST5) points of the patients in the EA group immediately before and after the flap surgery for 30 min at a frequency of 50 Hz to each point at a current that the patient could tolerate. The patients in the control group underwent flap surgery without applying electroacupuncture. Patients were asked to record their pain levels on the visual analog scale and the number of analgesic tablets they took during the 7 postoperative days on the given form. RESULTS: The total mean score of pain felt in the EA group(16.60 ± 2.78) was found to be significantly lower than that in the control group(31.37 ± 2.78)(P = 0.001). No significant difference was found between the groups regarding the amount of analgesics taken(4.77 ± 4.72, 5.82 ± 3.11)(P = 0.111). CONCLUSIONS: Our study shows that electroacupuncture application is beneficial in reducing pain after periodontal flap surgery. Overall, more research is needed to fully understand the effects of electroacupuncture on postoperative pain.

BACKGROUND: The increasing morbidity of liver cancer has led to a growing demand for transplantation. Split liver transplantation(SLT) is a promising way to ameliorate organ shortages. However, the safety and efficacy of SLT are still controversial. The aim of this study was to assess the clinical outcome of SLT in liver cancer patients at our center. METHODS: A total of 74 patients who received liver transplantation at a tertiary hospital from March 2019 to July 2023 were retrospectively studied, of whom 37 recipients underwent SLT and 37 recipients underwent whole-graft liver transplantation(WGLT). Clinical data were analyzed and compared between patients who underwent SLT and ***: SLT and WGLT were successfully performed, with no intraoperative transplantrelated mortality. Postoperatively, no significant differences in total bilirubin(TB, P=0.266), alanine transaminase(ALT, P=0.403) and aspartate transaminase(AST, P=0.160) levels within 30 d were detected between the two groups. The transplant-related mortality rates were 8.1% in the SLT group and 5.4% in the WGLT group within 30 d of surgery(P=1.000), and 10.8% and 8.1%, respectively, at 90 d after surgery(P=1.000). There were no significant differences in overall survival(OS) and progress-free survival(PFS) between the SLT and WGLT groups(P=0.910, P=0.190). CONCLUSION: Our results show that SLT does not imply additional risks in treating liver cancer compared with WGLT.
