Objective:To investigate the correlation between the clinical features and endoscopic ultrasound-guided portal pressure gradient (EUS-PPG) in patients with cirrhosis.Methods:A total of 148 patients with cirrhosis and portal hypertension who underwent EUS-PPG measurement at the Third Xiangya Hospital of Central South University from March 15, 2022 to June 20, 2023 were selected. The clinical data of patients collected before EUS-PPG measurement were analyzed. Variations in the EUS-PPG across different clinical data subgroups were analyzed. Multivariate linear regression analysis was used to explore the independent factors influencing EUS-PPG.Results:The EUS-PPG was significantly elevated in patients exhibiting red signs (16.62±5.33 mmHg VS 13.44±5.34 mmHg, t=3.616, P<0.001), gastroesophageal varices (15.78±5.30 mmHg VS 9.70±4.77 mmHg, t=4.247, P<0.001), hepatic encephalopathy (20.83±7.52 mmHg VS 14.92±5.35 mmHg, t=2.606, P=0.010), thrombocytopenia (15.66±5.39 mmHg VS 13.29±5.83 mmHg, t=2.136, P=0.034), hypoproteinemia (16.13±5.86 mmHg VS 14.12±5.03 mmHg, t=2.230, P=0.027), and an increased international normalized ratio (16.25±6.00 mmHg VS 14.40±5.11 mmHg, t=2.022, P=0.045). Conversely, the EUS-PPG was significantly reduced in patients with a history of splenectomy and devascularization (13.17±5.88 mmHg VS 15.73±5.34 mmHg, t=-2.379, P=0.019). The EUS-PPG in patients with varying degrees of ascites (no VS slight VS moderate or severe: 13.40±5.48 mmHg VS 15.90±5.49 mmHg VS 16.69±5.17 mmHg, F=5.188, P=0.007) and different Child-Pugh classifications (A VS B VS C: 14.07±5.05 mmHg VS 15.69±5.74 mmHg VS 17.64±5.99 mmHg, F=3.066, P=0.049) increased gradually. Multivariable linear regression analysis showed that red signs ( β=2.44, t=2.732, P=0.007), gastroesophageal varices ( β=4.45, t=2.990, P=0.003), ascites ( β=1.75, t=2.368, P=0.019), and hepatic encephalopathy ( β=5.82, t=2.644, P=0.009) were independent factors for the elevated EUS-PPG. Conclusion:There is a significant correlation between EUS-PPG and the clinical features related to the severity of cirrhotic portal hypertension, which indicates the feasibility of EUS-PPG in evaluating cirrhotic portal hypertension.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

OBJECTIVE: To investigate the short-term effectiveness of transverse antecubital incision in the treatment of failed closed reduction of Gartland type Ⅲ supracondylar humeral fractures (SHFs) in children. METHODS: Between July 2020 and April 2022, 20 children with Gartland type Ⅲ SHFs who failed in closed reduction were treated with internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision. There were 9 boys and 11 girls with an average age of 3.1 years (range, 1.1-6.0 years). The causes of injuries were fall in 12 cases and fall from height in 8 cases. The time from admission to operation ranged from 7 to 18 hours, with an average of 12.4 hours. The healing of the incision and the occurrence of complications such as nerve injury and cubitus varus were observed after operation; the elbow flexion and extension range of motion after removing the gypsum, after removing the Kirschner wire, and at last follow-up were recorded and compared, as well as the elbow flexion and extension and forearm rotation range of motion at last follow-up between healthy and affected sides; the Baumann angle was measured on the X-ray film, and the fracture healing was observed. At last follow-up, the effectiveness was evaluated according to the Flynn elbow function evaluation criteria. RESULTS: All incisions healed by first intention, and there was no skin necrosis, scar contracture, ulnar nerve injury, and cubitus varus. Postoperative pain occurred in the radial-dorsal thumb in 2 cases. The gypsum was removed and elbow flexion and extension exercises were started at 2-4 weeks (mean, 2.7 weeks) after operation, and the Kirschner wire was removed at 4-5 weeks (mean, 4.3 weeks). All the 20 patients were followed up 6-16 months, with an average of 12.4 months. The fracture healing time was 4-5 weeks, with an average of 4.5 weeks, and there was no complication such as delayed healing and myositis ossificans. The flexion and extension range of motion of the elbow joint gradually improved after operation, and there were significant differences between the time after removing the gypsum, after removing the Kirschner wire, and at last follow-up ( P<0.017). There was no significant difference in the flexion and extension of the elbow joint and the forearm rotation range of motion between the healthy and affected sides at last follow-up ( P>0.05). There was no significant difference in Baumann angle between the time of immediate after operation, after removing the Kirschner wire, and at last follow-up ( P>0.05). According to Flynn elbow function evaluation standard, 16 cases were excellent and 4 cases were good, the excellent and good rate was 100%. CONCLUSION The treatment of Gartland type Ⅲ SHFs in children with failed closed reduction by internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision has the advantages of complete soft tissue hinge behind the fracture for easy reduction and wire fixation, small incision, less complications, fast fracture healing, early functional recovery, reliable reduction and fixation, and can obtain satisfactory results.

Magnetic resonance imaging is commonly used in clinical work for its high resolution for soft tissue, and without radiation or interaction of bone interference. For ENT physicians, to read MRI accurately and retrieve more information from it would help the clinical work a lot. This review introduces the principles of MRI, the anatomy, the inflammatory disease, benign tumors and malignancies of the nasonasal tract.

The present study developed an oral hepatocyte growth factor (HGF) gene therapy strategy for gastric ulcers treatment. An attenuated Salmonella typhimurium that stably expressed high HGF (named as TPH) was constructed, and the antiulcerogenic effect of TPH was evaluated in a rat model of gastric ulcers that created by acetic acid subserosal injection. From day 5 after injection, TPH (1 × 10⁹ cfu), vehicle (TP, 1 × 10⁹ cfu), or sodium bicarbonate (model control) was administered orally every alternate day for three times. Then ulcer size was measured at day 21 after ulcer induction. The ulcer area in TPH-treated group was 10.56 ± 3.30 mm², which was smaller when compared with those in the TP-treated and model control groups (43.47 ± 4.18 and 56.25 ± 6.38 mm², respectively). A higher level of reepithelialization was found in TPH-treated group and the crawling length of gastric epithelial cells was significantly longer than in the other two groups (P < 0.05). The microvessel density in the ulcer granulation tissues of the TPH-treated rats was 39.9 vessels/mm², which was greater than in the TP-treated and model control rats, with a significant statistical difference. These results suggest that TPH treatment significantly accelerates the healing of gastric ulcers via stimulating proliferation of gastric epithelial cells and enhancing angiogenesis on gastric ulcer site.

OBJECTIVE: To assess the diagnostic value of 18-fluoro-2-deoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in detecting residual/recurrent nasopharyngeal carcinoma. METHOD: The literatures published between January 1990 and September 2013 were searched in PubMed, EM-BASE, EBSCO, Web of Science, CBM, CNKI, VIP and Wanfang databases. Two researchers independently selected studies, extracted data and assessed the quality of included studies according to the QUADAS tool. Summary sensitivity, specificity, diagnostic odds ratios (DOR), and receiver-operating characteristic (SROC) curves were obtained using Meta-Disc software. Subgroup analysis was also conducted. RESULT: Twenty-six studies were included in this meta-analysis, involving 1203 patients. The pooled sensitivity, specificity and DOR were 0. 92 (95% CI:0.89-0.94), 0. 87 (95% CI:0.84-0.90) and 51. 10 (95% CI:34.29-76.15), respectively. The area under the curve (AUC) and Q index estimate for PET/CT were 0. 9494 and 0. 8897, respectively. The results of subgroup analysis showed no significant differences between subgroups(P>0.05). CONCLUSION In a word, 18F-FDG PET/CT performed well for diagnosis of residual/recurrent nasopharyngeal carcinoma, with relatively high sensitivity and specificity.

This paper is aimed to assess the diagnostic value of MRI versus 99 Tcm-methylene diphosphonate (99 Tcm- MDP) bone scan (BS) for osseous metastases in patients with prostate cancer. The computer-based retrieval was conducted on PubMed, EMBASE, EBSCO, Web of Knowledge, the Cochrane Library and Ovid data bases to search for trials about diagnosing osseous metastases of prostate cancer with MRI and 99Tc"m-MDP BS. Selected with time acceptance and time exclusion criteria, the data quality were evaluated with QUADAS quality assessment tool and collected. We used the Meta-Disc software to conduct meta-analysis, and then calculated the pooled sensitivity, specificity and diagnostic odds ratio (DOR), drew the summary receiving operating characteristic (SROC) curve, and measured the area under curve (AUC) and Q value. Then five studies were included, involving 353 patients. The pooled sensitivity of MRI and BS was 0. 95 (95% CI 0. 90~0. 98) and 0. 67 (95% CI 0. 58~0. 75), respectively. The pooled specificity was 0. 97 (95% CI 0. 94~0. 99) and 0. 88 (95% CI 0. 83~0. 91), respectively. The pooled DOR was 402.99 (95% CI 119. 05 ~1364. 15) and 23. 85 (95% CI 1. 32~431. 48), respectively. The AUC was 0. 990 1 and 0. 624 1, respectively. The Q was 0. 958 7 and 0. 593 8. It can well be concluded that MRI is more effective than 99 Tcm-MDP BS in the diagnosis of osseous metastases in patients with prostate cancer.
