Objective To analyze the change in levels of high mobility group box 1 protein (HMGB1), interleukin-32 (IL-32), matrix metalloproteinase-9 (MMP-9)/tissue inhibitor of metalloproteinase-1 (TIMP-1) in peripheral blood of patients with lupus nephritis (LN) and their values in predicting prognosis. Methods A total of 86 patients with LN from October 2021 to June 2023 were selected and treated with induction therapy for 6 months. Based on remission status of the disease, patients were divided into remission group (n=66) and non-responder group (n=20). Baseline data, change in levels and reduction rates of HMGB1, IL-32 and MMP-9/TIMP-1, and the partial correlation of reduction rates of HMGB1, IL-32 and MMP-9/TIMP-1 levels in peripheral blood with treatment response as well as their predictive values for treatment response were compared between the two groups. Disease progression was compared between patients with different reduction rates of HMGB1, IL-32 and MMP-9/TIMP-1. Results HMGB1, IL-32 and MMP-9/TIMP-1 levels in the remission group decreased significantly at 1 and 3 months after treatment compared to before treatment (P < 0.05); the levels of HMGB1, IL-32 and MMP-9/TIMP-1 in the remission group were significantly lower than those in the non-responder group at 1 and 3 months after treatment (P < 0.05); the reduction rates of HMGB1, IL-32 and MMP-9/TIMP-1 levels in the remission group were significantly higher than those in the non-responder group at 1 and 3 months after treatment (P < 0.05). Partial correlation analysis showed that the reduction rates of HMGB1, IL-32 and MMP-9/TIMP-1 levels were independently significantly correlated with treatment response (P < 0.05). One and three months after treatment, the values of the area under the curve (AUC) for the combined prediction of remission by the reduction rates of HMGB1, IL-32 and MMP-9/TIMP-1 levels were 0.910 and 0.932 respectively, with the AUC being the largest at 3 months after treatment (P < 0.05). Patients were divided into high and low reduction rate subgroups based on theoptimal cut-off value from the ROC curve analysis at 3 months after treatment, and the disease progression rate was significantly lower in the high reduction rate subgroup than in the low reduction rate subgroup for HMGB1, IL-32 and MMP-9/TIMP-1 (P < 0.05). Conclusion The great change in levels of HMGB1, IL-32 and MMP-9/TIMP-1 in peripheral blood of LN patients is significantly correlated with treatment response and disease progression, and the combined detections of HMGB1, IL-32 and MMP-9/TIMP-1 levels at 1 and 3 months after treatment have high value in predicting the treatment response of LN patients.

Objective To explore the significance of abnormal lipid metabolism induced by hypoxia in mice with pulmonary hypertension.Methods Thirty male C57BL/6 mice were chosen and were randomly divided into the model group and the control group, each consisting of 15 animals.The mice in the model group were exposed to chronic hypoxia for the development of hypoxic pul -monary hypertension model , and the mice in the control group were housed in the chamber at the normal ambient air .Right heart cathe-terization was used to measure right ventricular systolic pressure in the 2 groups, Masson method was used to observe the small pulmona-ry vascular vessel remodeling , and the ELISA method was used to detect levels of high density lipoprotein ( HDL-C) , cholesterol ( TC) and low density lipoprotein (LDL-C).The expressions of HMG-CoA reductase (HMGCR), low density lipoprotein receptor (LDLR) and ATP binding cassette transporter A1 (ABCA1) gene in the liver tissue were detected by real-time quantitative PCR.Results The right ventricular systolic pressure (40.12 ±8.22) mmHg(1 mmHg=0.133 kPa) and right ventricular hypertrophy index (0.352 ± 0.050) in the model group were significantly higher than those in the control group (P<0.05).The pulmonary artery vascular wall of the model group was significantly thicker than that of the control group .The HDL-C level of the model group was (26.20 ±3.73) mg/dl, which was significantly lower than that of the control group (P<0.05).There was no statistical significance in the levels of TC and

Objective:To compare the therapeutic characteristics of anterior hybrid decompression and posterior cervical posterior laminectomy in the treatment of multilevel cervical spondylotic myelopathy.Methods:Thirty six cases of multilevel cervical spondylotic myelopathy patients treated by anterior hybrid decompression and thirty three cases of multilevel cervical spondylotic myelopathy patients treated by posterior cervical posterior laminectomy were involved.The general information,bleeding amount,operative time,cervical curvature D value,JOA score and incidence of postoperative complications of the two groups before and after surgery were compared.Results:There was no significant difference in the general information among the two groups(P＞0.05),including age (anterior group:56.23± 7.64 years old,posterior group:55.76± 8.18 years old),sex (anterior group:22 males/14 females,posterior group:20 males/13 females),cervical curvature D value (anterior group:7.41± 3.14,posterior group:8.19± 2.74),JOA score (anterior group:9.08± 1.09 scores,posterior group:8.82± 1.26 scores),disease course (anterior group:17.24± 7.36 months,posterior group:15.75± 5.78 months) and affected segment (anterior group:3.11 ± 0.26 segments,posterior group:3.24± 0.39 segments).The the amount of bleeding in the anterior group (anterior approach:221.79± 178.02 ml,posterior group:483.07± 434.25 ml) was lower than that of the posterior group(P＜0.05).The operative time (anterior group:196.54± 51.88 mins,posterior group:175.12± 54.93 mins) was longer,but there was no significant difference (P＞0.05).The cervical curvature D value and JOA score of posterior group were increased with the extension of surgery time.However,the cervical curvature D value of posterior group was decreased,but JOA score was increased.The incidence of bone unfinished,hoarseness and cerebrospinal fluid leakage were found in the anterior group,and axial pain and C5 nerve root paralysis were found in the posterior group.But there was no significant difference in the incidence of complications between the two groups (anterior group 14.89％,posterior group:12.12％)(P＞0.05).Conclusions:Anterior hybrid decompression and posterior cervical posterior laminectomy had their own advantages in the treatment of multilevel cervical spondylotic myelopathy.,The appropriate treatment should be taken according to the condition of patients.

‘Student-centered’ teaching model is the needs of higher medical education.In the process of education,we carried out comprehensive and systematic reforms by satisfying students' needs and improving students' ability as the main line.These reforms included change of teaching methods (the basic theory combined with clinical knowledge),increase of innovative experiments and change of evaluation system.These results showed that students were interested in these reforms,the innovation abilities of students were improved and students could pay more attention to the process of learning.
