Objective:To investigate the value of ultrasonic measurement of the ratio of optic nerve sheath diameter (ONSD) to eyeball transverse diameter(ETD) in the diagnosis and prognosis of intracranial hypertension in patients with craniocerebral trauma.Methods:A total of 120 patients with craniocerebral trauma treated in the Xingtai General Hospital of North China Medical and Health Group from December 2021 to January 2023 were perspectively selected, and they were divided into normal intracranial pressure group (73 cases) and intracranial hypertension group (47 cases) according to the results of intracranial pressure measurements, and the intracranial hypertension group was divided into good prognosis group (20 cases) and poor prognosis group (27 cases) according to the follow-up prognosis. The efficacy of ONSD, ETD and ONSD/ETD in intracranial hypertension diagnosis and prognosis assessment were analyzed by receiver operating characteristic (ROC) curve. Kaplan-Meier method was used to evaluate the 6-month risk of adverse prognosis of patients, and the comparison was made by Log-rank test.Results:The levels of intracranial pressure, ONSD, ONSD/ETD in the normal intracranial pressure group were lower than those in the intracranial hypertension group: (130.73 ± 23.63) mmH 2O (1 mmH 2O = 0.009 8 kPa) vs. (270.11 ± 35.78) mmH 2O, (5.47 ± 0.29) mm vs. (5.78 ± 0.44) mm, 0.246 ± 0.018 vs. 0.263 ± 0.018, there were statistical differences ( P<0.05). The scores of Glasgow Coma Scale (GCS), intracranial pressure, ONSD, ONSD/ETD in the good prognosis group were lower than those in the poor prognosis group: (5.50 ± 1.24) scores vs. (6.41 ± 1.34) scores, (256.15 ± 30.23) mmH 2O vs. (280.44 ± 36.56) mmH 2O, (5.62 ± 0.40) mm vs. (5.90 ± 0.44) mm, 0.254 ± 0.014 vs. 0.270 ± 0.017, there were statistical differences ( P<0.05). ROC curve analysis results showed that the area under the curve (AUC) of ONSD and ONSD/ETD for diagnosing intracranial hypertension in patients with craniocerebral trauma were 0.718 and 0.765, respectively, and the critical values were 5.87 mm and 0.263, respectively. The AUC of ONSD and ONSD/ETD predicting prognosis of intracranial hypertension patients was 0.677 and 0.763, respectively, and the critical values were 5.90 mm and 0.267, respectively. Grouped by the threshold of ONSD/ETD for the prognosis of intracranial hypertension (0.267), the incidence of adverse prognosis in ONSD/ETD > 0.267 group was higher than that in the ONSD/ETD≤0.267 group, there was statistical difference ( P<0.05). Conclusions:ONSD/ETD can be used as an index for diagnosis and prognosis of intracranial hypertension.

Background: There is still controversy whether the existence of esophageal heterotopic gastric mucosa (EHGM) and its histological type are related to the laryngopharyngeal symptoms. Aims: To analyze the clinical and histological characteristics of EHGM and its correlation with gastroesophageal reflux. Methods: A retrospective study was conducted in consecutive gastroscopy-proved EHGM cases from September 2018 to January 2020 at the Second Affiliated Hospital of Baotou Medical College. Besides clinical data review and questionnaire survey on reflux symptoms, histological typing of EHGM and immunohistochemistry were also performed in some cases. Results: A total of 1 229 cases of EHGM were recruited. The male-to-female ratio was 1.67:1, and middle-aged people were predominant. Most of the heterotopic mucosa were located 15-18 cm away from the incisors, and were mainly single. Two hundred and ninety-four cases (23.9%) were complicated with reflux esophagitis (RE), of which Los Angeles grade A and B accounted for 96.6%. Regurgitation/acid reflux (15.5 %) and heartburn (12.3%) were the most common esophageal symptoms, while extraesophageal symptoms were rare. Histological typing was obtained in 57 cases, of which, 37 (64.9%) were cardia-type, 18 (31.6%) were fundic-type, and 2 (3.5%) were mixed type. There were no significant differences in gender, age, location and number of EHGM, expression levels of H

To evaluate the effectiveness of epigallocatechin gallate [EGCG] in inhibiting corneal neovascularization in rat alkaline burn model. Corneal neovascularization model was induced by sodium hydroxide alkaline burn injury in SD rats. Rats were randomly divided into two groups and were given intraperitoneal injection with EGCG or PBS per day for up to 14 days respectively. Corneal inflammation and neovascularization area were assessed on days3, 7, and 14 after cauterization with digital photographs. Vascular endothelial growth factor [VEGF] and pigment epithelium derived factor [PEDF] mRNA levels were measured by reverse transcription-polymerase chain reaction [qRT-PCR]. The nucleartransfactor-kb [NF-?B] subunit P65 protein was assayed by immunohistochemistry. The differences of corneal inflammation scores between two groups were significant. The area of CNV between two groups had no significant difference on day3 but have significant difference on days 7 and 14.The PDEF mRNA expression in EGCG group was significantly higher and the expression of VEGF mRNA was lower than those in PBS group. The results of immunohistochemistry showed from day 7, expression of NF-kB P65protein was suppressed considerably in EGCG group. This study demonstrates that EGCG inhibits corneal neovascularization in a rat model induced by alkali burn

Objective To discuss the potential relationship between endometrial serous carcinoma (ESC) and tubal epithelial lesions by pathologic examination of fallopian tubes with ESC. Methods A total of 30 cases of typical ESC were reexamined and chosen by the pathologist. In each case, bilateral fallopian tubes were submitted to examination of pathologic morphology and immunostaining for p53, annexin Ⅳ(ANX-Ⅳ), human epidermal growth factor receptor 2(HER2)/neu, and high-mobility group protein A2 (HMGA2). Results Fallopian tubal epithelial lesions were found in 15 cases, including 9 cases tubal serous carcinoma, 2 cases serous tubal intraepithelial carcinoma (STIC) and 2 cases epithelial hyperplasia. Both sides of tubal serous carcinoma and STIC were found in 1 case. The results showed the positive expression for p53 in 26(87%)out of 30 endometrial malignant specimens tissues and 9(30%)tubal tissues samples (P>0.05). Twenty-five(83%)endometrial malignant specimens tissues and 6(20%)tubal tissues samples showed the positive expression of ANX-Ⅳ. Twenty-one(70%)endometrial malignant tissues and 7(23%) tubal tissues showed the positive expression of HER2/neu. Twenty-five(83%) endometrial malignant tissues and 6(20%)tubal tissues showed the positive expression of HMGA2. While, there were significant differences among the expression of three proteins between endometrium and the fallopian tube site (all P<0.05). Conclusions STIC may be associated with the occurrence of ESC. The expression of p53 was positively correlated between the fallopian tube and the endometrium. ANX-Ⅳ,HER2/neu and HMGA2 were extensively expressed in ESC.
