Favorable Outcomes of Liver Transplantation for Hepatopulmonary Syndrome.

BACKGROUND: Hepatopulmonary syndrome (HPS) is a pulmonary vascular complication of chronic liver disease, which develops insidiously as a result of chronic liver disease. The prognosis for untreated patients with HPS is extremely poor, and liver transplantation (LT) serves as the only effective means for treating this condition. Here, we performed a retrospective analysis to evaluate the efficacy of LT on the survival and long-term prognosis of patients with HPS. METHODS: Clinical data, including survival and postoperative efficacy, from patients with HPS from records as obtained over the period from January 1 to December 31, 2022. All records were from a waiting list for LT at the Beijing Friendship Hospital Affiliated with Capital Medical University. RESULTS: Among the 274 patients on the LT waiting list, 37 were diagnosed with HPS (13.50%) and were enrolled. Survival rates of patients with HPS receiving an LT were greater, whereas a statistically significant difference was obtained between patients with LT vs non-LT with moderate to severe HPS (P = .003). The overall time until death without LT was 4-72 days after their initial HPS diagnosis. Patients with HPS receiving an LT showed a significant improvement in the state of oxygenation after surgery (P = .001). CONCLUSION: Comprehensive preoperative screening of patients on the waiting list for LT is critical to identify those patients with HPS who would maximally benefit from LT. Survival rates of patients with moderate to severe HPS are significantly increased after LT, a procedure that should be performed as soon as possible in these patients with HPS.

[Preliminary clinical study on the effect of metformin on prognosis of patients with oral squamous cell carcinoma after surgical treatment].

PURPOSE: To investigate the effect of metformin on the prognosis of patients with oral squamous cell carcinoma after surgical treatment. METHODS: Three hundred and forty-six patients with oral squamous cell carcinoma after operation in Xiangya Hospital of Central South University from October 2015 to October 2016 were selected and divided into experimental group and control group. In the experimental group, 71 patients with oral squamous cell carcinoma received metformin after surgery. The control group included 275 patients without metformin after surgery of oral squamous cell carcinoma. The clinical follow-up results of patients in the two groups were compared. SPSS 21.0 software package was used to analyze the data. RESULTS: Compared with the control group, the recurrent rate of the experimental group was lower. The difference was more significant in male patients, patients with primary tongue tumor, patients with highly differentiated squamous cell carcinoma, patients with cervical lymph node metastasis, and patients with a history of chewing areca nut (P<0.05). CONCLUSIONS: Metformin can decrease postoperative recurrent rate and metastatic rate of oral squamous cell carcinoma after surgery.

[Expression and clinical significance of T lymphoma invasion and metastasis inducing factor 1 in oral squamous cell carcinoma].

PURPOSE: T lymphoma invasion and metastasis inducing factor 1 (TIAM1) overexpression has been reported in a variety of human cancers. However, the investigation of TIAM1 in oral squamous cell carcinoma (OSCC) was extremely rare. The aim of the study was to assess TIAM1 expression and explore its role in OSCC. METHODS: Immunohistochemistry staining was performed in 80 primary OSCC patients and 20 normal oral mucosa samples. The expression of TIAM1 and its association with clinicopathological parameters were analyzed using SPSS19.0 software package. RESULTS: TIAM1 expression was significantly stronger in OSCC tissues (91.25%) compared with normal oral mucosa (10.00%); TIAM1 overexpression was significantly correlated with histological grade (P=0.019), clinical stage (P<0.001) and lymph node metastasis (P=0.004), but not significantly correlated with sex or age. CONCLUSIONS: TIAM1 may play an important role in the occurrence, development and metastasis of OSCC, which may be a potentially therapeutic target in the future.
