Objective To compare the results of treatment with biodegradable ligaments and metallic fixation for total acromioclavicular joint dislocation. Methods Twenty eight patients with total acromioclavicular joint dislocation were treated with two different materials, 1) by Kirschner pin and steel wire or screw and steel wire tension band (MF group,16 cases), and 2) reconstructed by artificial coracoclavicular ligament and coracoacromial ligament (BF group,12 cases). There were 17 males and 11 females. All patients had acute dislocation. The time from injury to hospital admission varied from 0-8 days (average, 1.5 days). Results All patients were availble for an average duration of follow up of 39.5 months (range,8-70 months). The results were evaluated by radiographic representations and joint function according to Lazcano's standards. In BF group, 10 patients were assesed as good and 2 as fair. In MF group, 13 patients were assesed as good, 2 as fair and 1 as poor. There were no statistic differences between these two methods. Conclusion Biodegradable ligament fixation is believed to be a good simple method for the treatment of acromioclavicular joint dislocation without the necessity of a second operation for removal of implants.

AIM: To investigate the influence of the cornus officinalis glycosides (COG) on immunological function of corneal transplantation model of rats, and to clarify the immunosuppressive mechanism of COG through observing the activation of lymphocytes in blood. METHODS: Wister rats were used as recipients and SD rats were used as corneal graft donors, then the corneal allografts transplantation model on the closed colony rats were set up. Splenocytes proliferation and mixed lymphocyte reaction of Wister rats activated by ConA were observed. The phenotype change of CD4, CD8, CD25 in blood in different time postoperatively were observed by the di-sign flow cytometry, and the rate of CD4/CD8 was calculated. RESULTS: 1. The COG suppressed the proliferation of T lymphocytes and one-way mixed lymphocyte reaction on the corneal allografting. 2. The phenotype change of lymphocytes in boold was as follows: there was no significant difference between the different time of the CD4, CD8 expression and the CD4/CD8 rate in blood of the control group. The CD4 positive cells expressed CD25 postoperatively increased obviously. The CD4/CD8 rate of medicine group had the tendency to decrease. The CD4 positive cells expressed CD25 postoperation in the medicine group were less than that in the control group obviously. CONCLUSION: The suppression of the T lymphocyte proliferation, mixed lymphocyte reaction, CD molecule expressed by the activated T lymphocytes and the IL-2 receptor expression may be the main immunosuppressive mechanisms of Cornus officinalis glycosides on the cell-mediated immunity.

AIM: To observe the effect of ginkgolide B (GB) on glutamate-induced apoptosis in the cultured neurons of rat retina. METHODS: Neurons of rat retina were cultured and apoptosis was induced by glutamate. The neurons were cultured with different concentration of GB and the survival rate was monitored by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. The apoptosis in the cultured neurons and the expression of Bcl-2 and Bax were observed by flow cytometry. RESULTS: After exposed to glutamate, the survival rate and the number of Bcl-2 positive cells obviously decreased. At the same time, the number of Bax positive cells obviously increased, and the number of the apoptotic cells also obviously increased. Such phenomena were relieved by the treatment of ginkgolide B, with raise of survival rate and the expression of Bcl-2. Meanwhile, the expression of Bax and the apoptosis of neurocytes obviously decreased. CONCLUSIONS: Ginkgolide B protects retinal neurons from the virulence induced by glutamate. Such effects of GB might be brought about by increasing the expression of Bcl-2 while decreasing Bax, resulting in increasing the ratio of Bcl-2 to Bax and so reducing the apoptosis in the cultured neurons of rat retina.

Objective : To analyze the survival of patients with malignant mesothelioma, so as to provide insights into the management of malignant mesothelioma. Methods : Totally 36 patients with malignant mesothelioma admitted to Cixi Third People’s Hospital from October 2012 to January 2021 were enrolled, and the demographic features, exposure to asbestos, and diagnosis and treatment were retrospectively reviewed. The survival rate and median survival time were calculated with the life-table method, and the factors affecting the survival rate of malignant mesothelioma were identified using the Kaplan-Meier estimate and log-rank test. Results : The 36 patients with malignant mesothelioma included 6 men ( 16.67% ) and 30 women ( 83.33% ), and had a median age of 61 ( interquartile range, 14 ) years. There were 30 cases with pleural malignant mesothelioma ( 83.33% ) and 6 cases with peritoneal malignant mesothelioma ( 16.67% ), 32 cases ( 88.89% ) with a history of occupational exposure to asbestos, and 26 cases ( 72.22% ) receiving palliative treatment. The 1-, 2- and 3-year cumulative survival rates were 30%, 15% and 3%, respectively, and the median survival time was 0.71 years. In addition, there were no significant differences in the survival period among patients with malignant mesothelioma in terms of gender, age, route of asbestos exposure, duration of asbestos exposure, pathogenic site and treatment regimens ( P>0.05 ). Conclusion The 36 patients with malignant mesothelioma had a median survival period of 0.71 years, and no association was found between the survival period and asbestos exposure or pathogenic site.

Objective : To examine the diagnostic and prognostic value of long non-coding RNA (lncRNA) JPX in mesothelioma, so as to provide insights into diagnosis and prognosis of mesothelioma. Methods: Patients with clinically definitive diagnosis of mesothelioma from 2015 to 2019 that were sampled from asbestos processing plants in Zhejiang Province from 2015 to 2019 were recruited in the mesothelioma group, while healthy residents without asbestos exposure or asbestos-related diseases in the same area served as controls. Participants' demographics, pathologic diagnosis and imaging features were collected, and the expression of blood lncRNA JPX was detected using lncRNA microarrays. The diagnostic value of lncRNA JPX for mesothelioma was evaluated using the receiver operating characteristic (ROC) curve, and the correlation between lncRNA JPX expression and prognosis was examined among mesothelioma patients using survival analysis. Results: There were 17 subjects in the mesothelioma group, with a mean age of (65.71±8.36) years, and 34 subjects in the controls, with a mean age of (64.24±8.70) years. LncRNA microarray detected significantly high lncRNA JPX expression in mesothelioma patients, and higher blood lncRNA JPX expression was detected in the mesothelioma group than in the control group [median (interquartile range), 1.10 (1.31) vs. 0.89 (0.54); t'=-2.300, P=0.034]. The area under the ROC curve was 0.673 (95%CI: 0.507-0.839, P=0.046), and if the cutoff was 1.759, the sensitivity and specificity were 35.3% and 100.0%, respectively. Survival analysis showed no significant difference in the survival rate of mesothelioma patients between the high lncRNA JPX expression group and the low expression group (χ2=0.212, P=0.645). Conclusions LncRNA JPX overexpression is detected in the blood of patients with mesothelioma, and lncRNA JPX expression presents a diagnostic value for mesothelioma; however, it shows little prognostic value for mesothelioma.
