1.Molecular mechanism of bortezomib in mantle cell lymphoma
Journal of Leukemia & Lymphoma 2011;20(3):185-187
Mantle cell lymphoma is a distinct subtype of non-Hodgkin lymphoma (NHL) that remains incurable with the shortest survival time. Bortezomib is the first proteasome inhibitor used for the treatment of hematological malignant diseases, such as multiple myeloma and relapse or refractory mantle cell lymphoma (MCL). Investing the mechanism of bortezomib for MCL, including modulation of cell cycle, the influence of cell apoptosis, the disturbance of the MCL microenvironment and the cooperative action with other antineoplastic drugs, is helpful to make the treatment strategy for MCL.

Objective To explore the curative effect of knee flexion deformity on spastic cerebral palsy treatment method.Methods All of 30 patients with spastic cerebral and knee flexion deformity were randomly divided into two groups:traditional operation group and modified operation group,using the commonly used operation (In 15 cases,with traditional hamstring post surgery) and) modified operation (In 15 cases,with modified hamstring post surgery),two groups of patients were treated with Ilizarov external fixation drafting device in the correction of knee flexion deformity after soft tissue release.Adjustment began 7 days after the soft tissue release operation of external fixation,and stretched approximately 0.2 degrees each time,3 times/d,until knee flexion deformity was corrected to hyperextension for 10 degree and maintained for 3 weeks,and the flexion contracture degree of knee joint was measured every 2 weeks;then the Ilizarov external fixation drafting device was removed.Then wear a walking straight leg brace for more than 3 months,until the knee walking function is good.Clinical evaluation included the joint pain index,walking function index,knee flexion deformity degree and range of joint motion score of Dimeglio standard.Results Flexion contracture deformity of knee joint in 30 cases (60 knees) was corrected when Ilizarov external fixator was removed,knee extension to 0 degrees-5 degrees.The two groups of patients had the knee flexion angle range of-1.2 degrees to 13.3 degrees,with an average of (7.32°±3.41°) after removed of the walking straight leg brace,in which 4 cases (8 joints) got recurrent deformity of 10°-15° at the time of removing of the walking straight leg brace.Knee activity significantly was improved at the end of treatment.60 cases of knee joint activity were close to normal,with flexion of 100 degrees to 135 degrees,extension of 0 degrees to 10 degrees.Two groups of patients were statistically significantly improved before and after surgery.Curative effect comparison:The walking function index of the modified operation group was obviously superior to that of the traditional operation group,there was significant statistical difference.There were no statistically significant differences in pain index,knee flexion,and range of joint motion.Conclusion For the treatment of flexion deformity of the knee joint in spastic cerebral palsy,traditional surgery using the semitendinosus and gracilis,post and semimembranosus lysis,combined with the Ilizarov draft external fixation could improve the walking function of the patients,simplify the surgical incision and reduce trauma.As a result,modified hamstring post surgery is an ideal,effective treatment method.
3.Construction and validation of a predictive model for chronic hydrocephalus in patients with acute cerebral infarction after thrombolytic therapy
Chinese Journal of Postgraduates of Medicine 2024;47(12):1089-1093
Objective:To establish and validate a predictive model for chronic hydrocephalus in patients with acute cerebral infarction after thrombolytic therapy.Methods:The clinical data of 288 patients with acute cerebral infarction admitted to Linfen People′s Hospital from January 2020 to December 2022 were retrospectively collected, based on whether the patients had chronic hydrocephalus or not, they were divided into the hydrocephalus group (62 cases) and the control group (226 cases). The clinical characteristics of the two groups were compared, and the risk factors for chronic hydrocephalus in patients with acute cerebral infarction after thrombolysis treatment were analyzed by multivariate Logistic regression. Based on relevant risk factors, the predictive model for chronic hydrocephalus in patients with acute cerebral infarction after thrombolytic therapy were established and validated it by R4.0.3 software.Results:The age, rate of diabetes mellitus and massive cerebral infarction in the hydrocephalus group were higher than those in the control group: (70.81 ± 10.34) years old vs. (63.46 ± 10.34) years old, 50.00%(31/62) vs. 16.81%(38/226), 38.71%(24/62) vs. 15.93%(36/226), there were statistical differences ( P<0.05). The results of multivariate Logistic regression analysis showed that the age>65 years old, diabetes mellitus and massive cerebral infarction were the risk factors of chronic hydrocephalus after thrombolytic therapy for acute cerebral infarction ( P<0.05). A prediction model and randomly divided the dataset into a training set (202 cases) and a validation set (86 cases) by R4.0.3 software, the area under curve (AUC) of the receiver operating characteristic curve in the training set was 0.774 (95% CI 0.694 - 0.855), and the AUC of the validation set was 0.807 (95% CI 0.664 - 0.950). In the validation set, the model was subjected to the Hosmer-Lemeshow Goodness-of-Fit test, χ2 = 8.35, P = 0.400, indicating that the model had good reliability. Conclusions:The present predictive model has high value in predicting chronic hydrocephalus in patients with acute cerebral infarction after thrombolytic therapy, and can be used to identify patients at high risk of chronic hydrocephalus.

Objective This study aimed to observe the effect of Jiang Tang San Hao Formula(JTSHF)on systemic and intestinal inflammation,as well as on the NLRP3 inflammasome in type 2 diabetic mice(T2DM),and to elucidate its anti-diabetic molecular mechanisms.Methods Four-week-old male C57BL/6 N mice were used to establish the T2DM model using a high-fat diet combined with streptozotocin injection.The diabetic mice were randomly divided into the model,metformin,and JTSHF groups.A control group was also set to provide baseline comparisons.Each group of mice was orally administered with the corresponding medication daily.The metformin group was orally administered with 0.20 g/kg metformin,the JTSHF group was orally administered with 4.26 g/kg JTSHF,and the control group and model group were orally administered with an equal amount of sterile water continuously for 8 weeks.After an 8-week drug intervention via gavage,the lipopolysaccharide(LPS),tumor necrosis factor-alpha(TNF-α),interleukin 1 beta(IL-1β),and interleukin 6(IL-6)serum and colon levels were quantified using an enzyme-linked immunosorbent assay(ELISA).The pathological morphology of the colon was observed using hematoxylin and eosin staining.NOD-like receptor protein 3(NLRP3),apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),caspase-1,zonula occludens-1(ZO-1),occludin,and G-protein coupled receptor 43(GPR43)protein expression in the colon were assessed using immunohistochemistry.The mRNA expression levels of NLRP3,ASC,caspase-1,ZO-1,Occludin,and GPR43 in the colon were detected using Real-time PCR.Results The ELISA data revealed significant differences in inflammatory markers among the groups.Compared with the model group,the JTSHF group exhibited notably reduced LPS,TNF-α,IL-1β,and IL-6 levels(P<0.05).Moreover,compared with the model group,JTSHF treatment upregulated ZO-1,occludin,and GPR43 protein and mRNA expression in the colon and downregulated NLRP3,ASC,and Caspase-1 protein and mRNA expression(P<0.05).Conclusion The inflammatory reaction of T2DM mice is apparent.JTSHF effectively alleviates the systemic and intestinal inflammatory response of T2DM mice by inhibiting the NLRP3 inflammasome and repairing the intestinal mucosal barrier,highlighting the potential molecular mechanisms of the anti-diabetes effects of JTSHF.
