OBJECTIVE: To investigate the effects of three compounds extracted from Tripterygium wilfordii Hook (TW) on angiogenesis in the chick chorioallantoic membrane (CAM). METHODS: Fifty fresh Hongkong Mahua chicken eggs were divided into five groups: PBS-treated group, TW1-, TW2- and TW3-treated groups and Rg3-treated group. After disinfection, the eggs were incubated for six days in a constant temperature box with the temperature being controlled within 37.8 degrees C, then exposed CAM, laid the filter papers with specimen on the CAM, and the eggs were incubated for another two days. CAM was fixed with the mixture of methyl alcohol and acetone at room temperature for about 15 min, and then cutting the CAM, taking photos and observing the angiogenesis in the CAM. RESULTS: There were many CAM vessels in the PBS-treated group and the blood vessel net could be seen clearly. The number of CAM vessels in the TW1-, TW2- and TW3-treated groups (10 microg/egg) was much less than that in the PBS-treated group. Furthermore, the frame of the vessels was not clear, and the color was obscure. Inhibition rates of angiogenesis in the TW1-, TW2- and TW3-treated groups were 80%, 60% and 100% respectively, while the inhibition rate of angiogenesis in the Rg3-treated group (10 microg/egg) was only 10%. CONCLUSION: TW1, TW2 and TW3 can obviously restrain the angiogenesis in CAM and still need further study.

Objective To investigate the association between atrial fibrillation (AF) and epicardial adipose tissue (EAT) by echocardiography.Methods One hundred and thirty-eight patients of AF in First Affiliated Hospital of Chinese People's Liberation Army General Hospital from March 2014 to June 2016 were divided into two groups,including paroxysmal AF group with 87 casesand persistent AF group with 51 cases,and 112 cases of sinus rhythm were chosen as control group.Epicardial adipose tissue was measured using echocardiography in all patients,and the conventional parameters were recorded.One-way analysis of variance was used to compare the thickness of EAT in patients with paroxysmal AF group,persistent AF group and sinus rhythm group,and LSD-t test was used in further comparison between two groups.Multivariable logistic regression analysis was used to analyze the risk factors of AF.The receiver-operating characteristic (ROC) cure of EAT and left atrium diameter (LAD) were drawn to predict the incidence of AF.The correlation between EAT thickness and LAD was analyzed by Pearson correlation analysis.Results The thickness of EAT in patients with persistent AF,paroxysmal AF and sinus rhythm group were (4.75± 1.83),(4.32 ± 1.76) and (1.38 ± 0.68) mm,respectively.Epicardial adipose tissue was significantly larger in paroxysmal AF and persistent AF patients compared with that of sinus rhythm group,and the differences were statistically significant (t=-9.541,11.439,both P ＜ 0.01).Logistic regression analysis indicated that EAT thickness and LAD were independent risk factors of atrial fibrillation (odds ratio:3.17,95％ confidence interval:1.31-7.68,P ＜ 0.01;odds ratio:2.65,95％ confidence interval 1.69-4.15,P ＜ 0.05).The area under the curve (AUC) of EAT and LAD to predict presence of AF were 0.784 and 0.865,and the best threshold value were 4.45 mm and 40.00 mm,respectively.Pearson correlation analysis showed that the EAT thickness and LAD had significantly positive correlation (r=0.512,P ＜ 0.01).Conclusions The increase of EAT thickness is significantly correlated with the incidence of AF and is independent to traditional risk factors.Therefore,the increase of EAT thickness has certain clinical value to predict AF.

The urine protein levels in the two groups were positively correlated with LDL, TC, TG, aortic plaque area and aortic intimal thickness ( r=0.67, P=0.004; r=0.68, P=0.004; r=0.53, P=0.033; r=0.80, P<0.001; r=0.74, P=0.001), and negatively correlated with HDL ( r=-0.57, P=0.021). Conclusion:The severity of lupus nephritis is correlated with atherosclerosis and dyslipidemia in the early stage of systemic lupus erythematosus. Tofacitinib may reduce the degree of early arteriosclerosis and lupus nephritis in MRL/LPR mice, and reduce blood lipid levels, which may be effective in improving the prognosis of SLE and improving the survival rate of patients.

Objective The aim of this study was to investigate the dosimetric advantages of Gating in the treatment of prima-ry hepatic cancer with large segmentation. Methods A retrospective analysis of 10 patients with primary liver cancer from August 2017 to November 2018 after interventional therapy was performed using three consecutive phases of end-tidal phase to achieve pa-tient-controlled large-segment radiotherapy. Ten patients underwent 4DCT localization scan,and 10 respiratory phase sequences were reconstructed by respiratory wave-form,and the images were transmitted to the MIM6. 7. 6 workstation. In the MIM workstation, full-time phase maximum density projection(MIP-10),full-time phase average density projection(Mean-10),end-expiration 3 phase maximum density projection(MIP-3) and end-expiration 3 phase average density projection( Mean-3) were generated re-spectively,where MIP was used for target delineation and Mean for dose calculation. The radiotherapy doctor delineated IGTV-10 and IGTV-3 on the MIM workstation,and released CTV-10,CTV-3,PTV-10 and PTV-3 to compare the volume differences of the target area. After the target area was drawn,the image was transmitted from the MIM workstation to the Eclipse treatment planning sys-tem,and the full-time phase plan(Plan-10)with the same conditions and three consecutive phase-phase gating plans(Plan-3) were prepared. The prescriptive dosage was given at 50 Gy/10 f/2weeks. Comparing the HI and CI of the target area,the comparison of organs at risk included: the average dose of liver Dmean,the irradiation volume of liver less than 15Gy,the Dmax of small intestine, the Dmax of colon, the Dmax of stomach, the average dose of the kidney Dmean, the heart Dmax, and the spinal cord Dmax. Results The volume of the target area delineated at the end of expiratory phase was less than that of the target area outlined by the full-time phase in IGTV,CTV and PTV,and the difference was statistically significant(P<0. 05). In the two groups of seven field coplanar lage-segment radiotherapy plans,the 3-phase respiratory gating plan significantly reduced the dose of the organs at risk, and the difference was statistically significant(P<0. 05). At the same time,there was no statistically difference in the HI and CI be-tween of the two groups(P>0. 05). Conclusion The gated target area delineation and planning design of the three consecutive pha-ses of end-tidal phase reduce the volume of IGTV,CTV and PTV target regions compared with the selection of full-time phase,and have obvious advantages in the planned dosimetry. The irradiation dose that threatens the organs is worthy of being promoted and ap-plied in the large-scale radiotherapy of liver cancer.

Objective:To observe the therapeutic effect of intraocular lens (IOL) protected phacoemulsification (PHACO) in patients with hard nucleus cataract.Methods:A randomized controlled clinical study was conducted.A total of consecutive 120 patients (120 eyes) with hard nucleus cataract of Emery grade Ⅳ or Ⅴ were enrolled from January 2019 to May 2022.The patients were randomly divided into PHACO group receiving routine PHACO, IOL protected PHACO group receiving PHACO under IOL protection, and extracapsular cataract extraction (ECCE) group receiving ECCE, with 40 cases (40 eyes) in each group.Finally, 99 patients completed the follow-up, including 30 cases (30 eyes) in PHACO group, 35 cases (35 eyes) in IOL protected PHACO group, and 34 cases (34 eyes) in ECCE group.The total operation time, intraoperative PHACO time and cumulative energy release of each patient were recorded.The corneal endothelial cell density (ECD), coefficient of variation in endothelial cell area (CV), hexagonal endothelial cell ratio (6A), corneal astigmatism and the number of eyes with different grades of uncorrected visual acuity were measured and compared after 3-month follow-up.The intraoperative and postoperative complications were recorded.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Yanbian University Hospital (NO.2023002).Patients were informed of study content and purpose and signed a consent form before treatment.Results:There was no significant difference in ultrasonic energy and time between PHACO group and IOL protected PHACO group ( P=0.691, 0.982).The total operation time was (38.81±2.73) and (36.45±3.45) minutes in PHACO group and IOL protected PHACO group, significantly shorter than (69.60±4.35) minutes in ECCE group (both at P<0.001).There was no significant difference in age, sex, lens nucleus hardness and other baseline data among the three groups before operation (all at P>0.05).Three months after operation, the number of patients with higher uncorrected visual acuity in PHACO group and IOL protected PHACO group was larger than that in ECCE group ( P=0.006, 0.007).The ECD and 6A in IOL protected PHACO group were (2 155.57±177.88)/mm 2 and (41.31±5.18)%, respectively, which were significantly higher than (1 912.64±224.11)/mm 2 and (36.18±3.27)% in PHACO group, and the CV in IOL protected PHACO group was (50.34±5.90)%, which was lower than (55.67±3.30)% in PHACO group, showing statistically significant differences ( P=0.007, 0.003, 0.005).At 1 week and 3 months after the operation, the corneal astigmatism was significantly lower in IOL-protected PHACO group than in ECCE group, but higher than in PHACO group, and the difference were statistically significant (all at P<0.05). Conclusions:Compared with conventional PHACO, IOL-protected PHACO can effectively reduce the damage of corneal endothelium caused by ultrasonic energy, shorten the operation time and reduce postoperative inflammatory reaction compared with ECCE, and does not significantly increase postoperative corneal astigmatism.IOL-protected PHACO is an effective improved surgical method for patients with hard nucleus cataract.

Objective:To investigate the expressions and significance of cyclin D2 and bcl-2 in diffuse large B-cell lymphoma (DLBCL) and their clinical significances.Methods:The tissues of 87 DLBCL patients undergoing resection and 23 patients with lymphoid tissue reactive hyperplasia (RLH) in the First Central Hospital of Baoding from January 2015 to March 2020 were collected. Immunohistochemistry method was used to detect the expressions of cyclin D2 and bcl-2 in tissues of DLBCL and RLH, and the relationship between the expressions of cyclin D2 and bcl-2 as well as the association with the clinicopathological features of DLBCL patients.Results:The positive rates of cyclin D2 protein in DLBCL and RLH were 33.3% (29/87) and 2.0% (1/23), the positive rates of bcl-2 protein in DLBCL and RLH were 60.9% (54/87) and 7.0% (3/23); the positive rates of cyclin D2 and bcl-2 in DLBCL were higher than those in RLH, and the differences were statistically significant( χ2=7.566, P=0.006; χ2=17.512, P < 0.01). The expressions of cyclin D2 and bcl-2 proteins were related to the Ann Arbor staging and immunophenotype of DLBCL patients (all P < 0.05), while not related to age, gender, cancer location, tissue type (all P > 0.05). There was a positive correlation between the expressions of cyclin D2 and bcl-2 protein in DLBCL ( r=1.000, P < 0.01). Conclusions:cyclin D2 and bcl-2 may be related to the development and progression of DLBCL, and both may have some synergies.
