Objective:To evaluate the clinical value of CD4 + T lymphocyte subsets such as helper Th2 in patients with recurrent uveitis (BU) in Beh?et′s disease (BD). Methods:The clinical data of 153 hospitalized patients diagnosed with Beh?et′s disease from January 1, 2020 to June 30, 2023 in the Second Hospital of Shanxi Medical University were retrospectively analyzed. The subsets of CD4 + T lymphocytes were measured, including helper T cells (Th cells) such as Th1, Th2, Th17 and regulatory T cells (Treg cells), biochemical lipid indexes (TC, TG, etc.), the frequency of oral ulcers in the past 1 year, the frequency of genital ulcers in the past 1 year, and drug use before admission;According to whether there was ocular involvement and uveitis, 153 cases of BD were divided into Beh?et non-uveitis group (non-BU group) and Beh?et uveitis group (BU group). The above indexes and independent correlation factors of recurrent BU were compared between BU group and non-BU group;The above indexes and independent correlation factors of recurrent BU were compared between BU group and non-BU group. The levels of cytokines and ICBD total score, the correlation between ICBD total score and various cytokines, and the diagnostic performance of Th2 cells were compared between BU group and non-BU group.The statistical methods were Mann-Whitney U test, independent sample t test, Chi-square test, multiple logistic regression analysis, Pearson correlation analysis and receiver operating characteristic curve (ROC) analysis. Results:①The levels of Th1, Th2, Th17 cells, TC and TG in BU group were higher than those in non-BU group [133.87 (93.38, 229.87)/μl vs. 102.51(64.25, 149.23)/μl] and [9.43 (5.84, 14.13)/μl vs. 6.78(4.23, 9.44)/μl], [15.53 (9.36, 25.27)/μl vs. 9.83(5.46, 14.76)/μl], [4.21 (3.89, 4.90) mmol/L vs. 3.89(3.37, 4.34)mmol/L)], [1.43(1.00, 2.21)mmol/L vs. 0.96(0.69, 1.38)mmol/L], The differences were statistically significant ( Z=-3.24, Z=-3.05, Z=-3.94, Z=-2.25, Z=-3.47; all P<0.05); There was no statistical significance in Chi-square test between the two groups ( χ2=5.69, P>0.05).②The levels of IL-2, IL-10 and total ICBD score in BU group were higher than those in non-BU group, with statistical significance ( Z=-2.12, Z=-2.29, t=-6.48; all P<0.05). ③ The results of multiple logistic regression analysis showed that Th2 was an independent correlation factor for BU [ OR value (95% CI) was 1.143(1.007, 1.298), P=0.039]. The total score of BU patients was correlated with Th2 and Th17 cells. ROC analysis showed that the sensitivity of Th2 in diagnosing BU was 68.8%, the specificity was 49.5% and the area under the curve (95% CI) was 0.697 (0.585, 0.809) (P=0.001). Conclusion:CD4 + T lymphocyte subsets such as the absolute number of Th2 cells are related to BU, which is an important indicator to observe the severity of disease progression in BU patients, and has certain clinical value in evaluating the recurrence of BU in BD patients.

Preeclampsia (PE), a multisystem disorder in pregnancy, is one of the leading causes of perinatal morbidity and mortality that poses financial and physical burdens worldwide. Preterm PE with delivery at <37 weeks of gestation is associated with a higher risk of adverse maternal and perinatal outcomes than term PE with delivery at ≥37 weeks of gestation. A myriad of first trimester screening models have been developed to identifying women at risk of preterm PE. In fact, the Fetal Medicine Foundation (FMF) first trimester prediction model has undergone successful internal and external validation. The FMF triple test enables the estimation of patient-specific risks, using Bayes theorem to combine maternal characteristics and medical history together with measurements of mean arterial pressure, uterine artery pulsatility index, and serum placental growth factor. Establishing a quality control process for regular monitoring and to ensure data standardization, reliability, and accuracy is key to maintaining optimal screening performance. The rate of preterm PE can be reduced by 62% by using the FMF prediction model, followed by the administration of low-dose aspirin. Recent evidence has also demonstrated that metformin has the potential for preventing PE in patients at high-risk of the disorder. In this article, we will summarize the existing literature on the different screening methods, different components of risk assessment, therapeutic interventions, and clinical implementation of the first trimester screening and prevention program for PE with specific considerations for Chinese mainland.

Objective:To study the expression of MMP-9 in nasal NK/T cell lymphoma, HIF-1a and its relationship with the clinical and pathologic characteristics. Methods:46 cases ( case group) of paraffin block specimens from patients with pathologically confirmed nasal NK/T cell lymphoma were collected from the Affiliated Hospital of Youjiang Medical College For Nationalities,the same period endoscopy turbinate mucosa were confirmed by pathology in 20 cases of chronic inflammation of mucosa specimens ( control group) , respectively HE staining and immunohistochemistry handle two specimens, observation of the expression differences of two groups of specimens of pathological morphology, MMP-9 and HIF-1a, and to analyze its relationship with the clinical and pathological features of the patients. Results: Case group HIF-1a expression rate 67. 39% (31/46), expression was 6. 52% (3/20) in control group. , the HIF-1a case group were significantly higher than control group (P<0. 05). Case group MMP-9 expression rate 71. 74%(33/46), in the control group expression was 6. 52% (3/20), MMP-9 expression in the case group was significantly higher than control group (P<0. 05). HIF-1a and MMP-9 in positive expression in Ann Arbor staging (Ⅲ-Ⅳ), lymph node metastasis, vascular invasion in patients with nasal NK/T cell lymphoma tissue appeared a high expression ( P< 0. 05 ) . Conclusion: Nasal NK/T cell lymphoma tissue of patients with HIF-1a, MMP-9 presented high expression, and there was a certain relationship between Arbor Ann stage (Ⅲ-Ⅳ) , lymph node metastasis and vascular invasion.

Objective To study the expression of Survivin protein and its relation with the expression of Bcl-2, Bax in the tropho- blasts of human normal placenta. Methods The normal placental tissues (8 -9week ,18-23 week and 37-40week) were fixed, embed- ded, sectioned, and Survivin, Bcl-2, and Bax in the trophoblasts were detected with immunnohistochemistry. Result As the gestational age advanced , the staining intensity of Survivin in the trophoblasts was significantly decreased from the first trimester group to the second trimes- ter group to the term group (PU value: 11.74±0.8,9.95±0.43,8. 83 ~ O. 67, respectively, P <0.01 ), while the staining intensity of Bcl-2 and Bax in trophoblast was significantly increased (PU value of Bcl-2 : 4.33±0.60, 5.00±0.75,6.87±0.45, respectively, P<0.01 and PU value of Bax: 9.82±1.12,16.00±1.05,27.48±2.10, respectively, P <0.01 ). Expression of Survivin in trophoblasts has no rela- tionship with the expression of Bcl-2 and Bax (P>0.05 ). Conclusion Survivin may take part in the development of human normal pla- centa through the way of suppressing the apoptesis in trophoblasts. Expression of Survivin in trophoblasts has no relationship with the expres- sion of Bcl-2 and Bax, which indicate that they regulate apoptesis of trophoblasts via different biological pathways.
