Objective To investigate the effects of different stimulation of electroacupuncture on the protein expressions of SOCS1 and SOCS3 in rabbits with acute facial nerve injury; To determine the better stimulation. Methods New Zealand rabbits were treated with special hemostatic forceps for 5 min, and the length of the lesion was about 2.5 cm. The model of facial nerve injury was induced. The experiment was divided into blank group, sham-operation group, model group, and electoracupuncture weak-, medium-, and strong-stimulation group. The model group received no intervention after surgery. After treatment, the damaged facial nerve of each group was intercepted. The protein expressions of SOCS1 and SOCS3 mediated by negative feedback regulation of JAK-STAT were detected by ABC-ELISA. Results Compared with the blank group, the protein expressions of SOCS1 and SOCS3 in the model group increased (P<0.01). Compared with the model group, the protein expressions of SOCS1 and SOCS3 protein in electroacupuncture weak- stimulation group decreased (P<0.01). Conclusion Electroacupuncture can make SOCS1, SOCS3 protein expressions normal for acute facial nerve injury, and acupuncture treatment effect does not increase with the increase of stimulation.

Objective:To investigate the prognostic significance of D-dimer level in patients with diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of 70 newly diagnosed DLBCL patients who were admitted to Tianjin People's Hospital from January 2015 to June 2019 were retrospectively analyzed. The optimal cut-off value of D-dimer for survival was determined according to the receiver operating characteristic (ROC) curve, and the patients were grouped. The differences of coagulation related indexes and clinicopathological features between patients with different D-dimer levels were compared. Kaplan-Meier method was used for univariate analysis of overall survival (OS), and Cox regression model was used for multivariate analysis of OS.Results:According to ROC curve, the best cut-off value of D-dimer for survival was 0.75 mg/L. The proportion of patients with different clinical staging, international prognostic index score, lactate dehydrogenase level had statistically significant differences between the D-dimer ≥0.75 mg/L group (36 cases) and <0.75 mg/L group (34 cases) (all P < 0.05). The prothrombin time of D-dimer ≥ 0.75 mg/L group and < 0.75 mg/L group were (13.5±0.9) s and (13.0±0.8) s, respectively, and the activated partial thromboplastin time were (37±5) s and (34±6) s, respectively,and the differences were statistically significant (all P < 0.05). Univariate analysis showed that the 5-year OS rates of DLBCL patients with Ann Arbor stage Ⅲ-Ⅳ, international prognostic index score > 2, lactate dehydrogenase level > 240 U/L, B symptoms, D-dimer level ≥0.75 mg/L were decreased (all P < 0.05). Multivariate Cox regression analysis showed that D-dimer ≥0.75 mg/L was an independent risk factor for OS of DLBCL patients ( HR=0.368, 95% CI 0.144-0.944, P= 0.038). Conclusion:The level of D-dimer can be used as a clinical indicator to judge the prognosis of DLBCL patients, and the prognosis of patients with high D-dimer level is poor.

This study was purposed to detect the expression of transforming growth factor β1 (TGF-β1) and its receptors (TGF-βR) and to investigate their roles in pathogenesis of immune thrombocytopenic purpura (ITP). The expressions of TGF-β1 and their receptors TGF-βRI, TGF-βRII and TGF-βRIII in the peripheral blood of patients with ITP and healthy persons were detected by the real-time PCR, and differences of their expression levels were analysed. The results showed that the expression of TGF-β1 and TGF-βRII mRNA in ITP patients was significantly higher than that in the healthy controls, while the TGF-βRI mRNA expression in ITP patient was significantly lower than that in the controls. The expression of TGF-βRIII was not statistically different between the two groups. It is concluded that TGF-β1 and its receptors including TGF-βRI and TGF-βRII express abnormally in the peripheral blood of ITP patients, which suggests that the TGF-β signaling pathway probably play a vital role in the pathogenesis of the ITP.
