ObjectiveTo evaluate the clinical efficacy and safety of Tongluo Mingmu capsules in the treatment of diabetic retinopathy with blood stasis， collateral obstruction， and Qi and Yin deficiency syndrome. MethodA randomized， double-blind， positive-control， and multi-center clinical trial design method was used. 416 patients with diabetic retinopathy with blood stasis， collateral obstruction， and Qi and Yin deficiency syndrome in four test centers were included （the ratio of the treatment group to the control group was 3∶1）. On the basis of standardized hypoglycemic treatment， the treatment group was given both four Tongluo Mingmu capsules and two Calcium Dobesilate capsule agents three times a day， while the control group were given both two Calcium Dobesilate capsules and four Tongluo Mingmu capsule agents three times a day. The course of treatment was 12 weeks. The curative effect of Tongluo Mingmu capsules was evaluated by comparing the comprehensive curative effect of diabetic retinopathy， traditional Chinese medicine（TCM） syndrome score， corrected visual acuity， fundus changes， fundus fluorescence angiography， and other curative effect indexes before and after treatment in the two groups. At the same time， general examination， laboratory examination， and adverse events were performed to evaluate the safety of the drug. ResultThe baseline demographic data and disease characteristics of the treatment group and the control group were balanced and comparable， with the difference not statistically significant. After 12 weeks of treatment， the total effective rate of the comprehensive curative effect of diabetic retinopathy in the treatment group （61.0%， 189/310） was better than that in the control group （44.1%， 45/102）， and the difference was statistically significant （χ²=8.880， P<0.01）. The total effective rate of TCM syndromes in the treatment group （88.4%， 259/293） was better than that in the control group （69.9%， 65/93）， and the difference was statistically significant （χ²=17.927， P<0.01）. The disappearance rate of dry eyes （χ²=8.305）， dull complexion （χ²=4.053）， lassitude （χ²=10.267）， shortness of breath （χ²=8.494）， and dry stool （χ²=8.657） in the treatment group was higher than that in the control group， and the difference between the groups was statistically significant （P<0.05， P<0.01）. In terms of improving corrected visual acuity （χ²=8.382）， fundus changes （χ²=6.026） ， the treatment group was significantly better than the control group （P<0.05）. During the trial， the incidence of adverse events in the treatment group and the control group was 1.3% and 2.9%， respectively. There was no significant difference between the two groups. In addition， there were no serious adverse events and adverse events leading to withdrawal in both groups. ConclusionTongluo Mingmu capsules can improve the comprehensive curative effect of diabetic retinopathy and enhance the efficacy of TCM syndromes， visual acuity， fundus changes， and fundus fluorescein angiography， with great safety. Therefore， it can provide a new alternative therapeutic drug for patients with diabetic retinopathy.

Objective To discuss the feasibility and safety of simultaneous bilateral adrenal vein sampling(AVS)using two 4F-MPA1 catheters via right elbow vein access.Methods A total of 51 consecutive patients with primary aldosteronism,who received simultaneous bilateral AVS using two 4F-MPA1 catheters(one of the two catheters was shaped into pig tail figure)via right elbow vein access at Xiangyang Municipal Central Hospital between October 2021 and October 2022,were enrolled in this study.The used catheter,the success rate of simultaneous bilateral AVS,and the incidence of complications rate were calculated.Results The 4F-MPA1 catheter was used for all of the right AVS,while a specially shaped 4F-MPA1 catheter was used for the main trunk vein AVS of the left adrenal gland and the central vein AVS of the left adrenal gland.The success rate of simultaneous bilateral AVS was 92.2%(47/51).Adrenal hematoma occurred in one patient(1.96%).Conclusion The technique of simultaneous bilateral AVS using two 4F-MPA1 catheters via right elbow vein access is simple to operate,less traumatic,and clinically safe and feasible.However,due to the small sample used in this study,the clinical value of this technique still needs further investigation and verification.

ObjectiveTo explore the association between short-term exposure to atmospheric fine particulate matter （PM_2.5） and ozone （O₃） and systemic inflammatory indicators in patients with pneumonia， and to identify the susceptible populations. MethodsFrom September 2018 to April 2020， data of 1 480 patients admitted for pneumonia was collected from a tertiary hospital in Taiyuan City. Generalized additive models （GAMs） were used to explore the associations between PM_2.5 and O₃ exposure and inflammatory indicators of patients with pneumonia； and to explore the susceptibility factors and susceptible populations to PM_2.5 and O₃ exposures through stratified analyses. ResultsThe short-term exposure to PM_2.5 was associated with changes in peripheral blood C-reation protein （CRP）， erythrocyte sedimentation （ESR）， easinophil （EOS）， neutrophil （NEU） and neutrophil-lymphocyte ratio （NLR） in patients with pneumonia， and there were different degrees of hysteresis effects， with the effect values reaching a maximum at lag03， lag03， lag0， lag03， lag03， respectively， which were 4.13% （95%CI： 0.43%‒7.84%）， 3.10% （95%CI： 0.24%‒5.97%）， 5.27% （95%CI： 3.12%‒7.42%）， 1.85% （95%CI： 0.36%‒3.34%）， and 2.53% （95%CI： 0.53%‒4.74%） for every 10 μg·m^-3 of PM_2.5. The changes in O₃ concentration were associated with the elevation of peripheral blood PCT and ESR in patients with pneumonia， and their effect values all reached the maximum at lag01 d， every 1 μg·m^-3 of O₃ elevation increased by 0.38% （95%CI： 0.04%‒0.73%） and 0.47% （95%CI： 0.19%‒0.76%）， respectively. Stratified analyses showed that the associations of PM_2.5 with peripheral blood CRP， ESR， NEU， and NLR in pneumonia patients were more significant in males， the elderly， and those with onset in the cold season； the associations of O₃ with peripheral blood PCT and ESR in pneumonia patients were more significant in the elderly and those with onset in the warm season， and the peripheral blood CRP and PCT in female patients with pneumonia were more susceptible to the changes of O₃. ConclusionShort-term exposure to atmospheric PM_2.5 and O₃ are positively associated with changes in inflammatory indicators in patients with pneumonia， and the effects of PM_2.5 on patients with pneumonia are more extensive than those of O₃， with a longer lag effect. In addition， elderly patients with pneumonia are more sensitive to air pollution， male patients with pneumonia are more sensitive to PM_2.5， and female patients with pneumonia are more sensitive to O₃. Cold and warm seasons can exacerbate the effects of PM_2.5 and O₃ on inflammatory indicators in patients with pneumonia， respectively， and the patients must be protected well.

Objective:To explore the application effect of hydration therapy in patients with intermittent claudication (IC) of peripheral arterial disease, and to provide reference for clinical application.Methods:A randomized controlled trial method was used to select 86 patients with IC of peripheral arterial disease who attended the Department of Vascular Surgery of Shanxi Bethune Hospital from June to September 2023 as the study subjects by convenience sampling method, and they were divided into the control group and the intervention group by using the method of randomized numerical table, each group had 43 cases. In the control group, routine care was provided, and in the intervention group, hydration therapy was implemented on the basis of the control group. Ankle-brachial index, transcutaneous partial pressure of oxygen, and claudication distance were assessed in both groups 1d before and 6 months after the intervention.Results:Forty-two patients in each group completed the study, 21 males and 21 females, aged (61.33 ± 8.93) years in the intervention group; 24 males and 18 females, aged (61.33 ± 9.01) years in the control group. Compared with the ankle-brachial index, transcutaneous oxygen partial pressure and limp distance of the 2 groups 1 d before intervention, the differences were not statistically significant (all P>0.05), and 6 months after the intervention, the transcutaneous oxygen partial pressure of the patients in the intervention group was (37.69 ± 8.86) mmHg (1 mmHg=0.133 kPa), and that of the control group was (29.69 ± 7.79) mmHg, and the differences between the 2 groups were statistically significant ( t=4.40, P<0.05). The differences in patients′ transcutaneous partial pressure of oxygen and limp distance before and after intervention in the intervention group were -7.00 (-13.00, -1.75) mmHg and -50.00 (-100.00, 0.00) m, respectively, and in the control group were 0.01 (-1.00, 1.00) mmHg and 0.01 (-1.25, 20.00) m, respectively, and the differences between the 2 groups were statistically were statistically significant ( Z=5.59, 4.33, both P<0.05). Conclusions:Hydration therapy improves transcutaneous oxygen partial pressure values and claudication distance in patients with peripheral arterial disease IC, and improves microcirculation of the affected limbs in patients.

Objective: To explore the relationship between handgrip strength (HGS) and pulmonary function (PF) in college students with sedentary lifestyle, so as to provide a reference for taking HGS as an essential factor of PF. Methods: In March 1-5, 2023, a total of 44 college students were recruited and were divided into the sedentary group (22) and exercise group (22) according to the International Physical Activity Questionaire (IPAQ), with 22 students in each group. Independent sample t-test was used to compare the indexes between groups, pearson correlation coefficient was used to determine the correlation between HGS and PF. Multiple linear regression analysis was used to determine the predictive model of PF. Results: There were statistical significance of the correlations between HGS and FVC, MEP, PEF, FEV1, FIVC, MIP, and PIF ( r=0.79, 0.47, 0.44, 0.60, 0.72, 0.53 , 0.49, P <0.01). When gender, physical activity, age, height, weight, and HGS were included as predictors in the regression model, height and HGS had significant effects on FVC ( R 2=0.75, F= 60.55 , P <0.01), weight and HGS had a good predictive effect on FIVC ( R 2=0.67, F=41.77, P <0.01). Conclusion HGS is significantly associated with PF in college students with sedentary lifestyle. Therefore, HGS can be used as an important indicator to predict the PF status of habitual sedentary college students.

Objective:To explore the factors influencing complete remission in patients with diffuse large B-cell lymphoma (DLBCL), and to explore the effect of the interaction of Karnofsky performance status scale (KPS) scores and the level of lactate dehydrogenases (LDH) on whether patients with DLBCL are completely relieved.Methods:The clinical data of 373 DLBCL patients admitted to Shanxi Province Cancer Hospital from January 2014 to December 2020 were retrospectively analyzed. SPSS 25.0 logistic regression model and Cox proportional risk regression models were used to explore the factors affecting complete remission in patients with DLBCL and to explore whether there was a multiplicative interaction between the factors. For factors with multiplicative interactions, the Matrix package, epiR package, and survival package in R 4.2.0 software were used to analyze whether there was an additive interaction. The relative excess risk of interaction (RERI), attributable proportion due to interaction (AP), and the synergy index (S) were used to evaluate the presence of additive interactions.Results:Elevated β 2 macroglobulin (β 2-MG), KPS scores below 80, and elevated LDH were risk factors for incomplete remission in patients with DLBCL (all P < 0.05). The risk of incomplete remission in patients with elevated β 2-MG, KPS scores below 80 and LDH was 1.971 times ( OR = 1.971, 95% CI 1.161-3.346), 2.056 times ( OR = 2.056, 95% CI 1.057-4.000) and 3.351 times ( OR = 3.351, 95% CI 1.783-6.300) higher than those in patients with normal β 2-MG, KPS scores above 80 and non-elevated LDH, respectively. There was a negative multiplicative interaction between the two risk factors of KPS scores below 80 and elevated LDH ( OR = 0.317, 95% CI 0.126-0.785). The estimated value of RERI, AP and S was -2.07 (95% CI -4.79-0.64),0.50 (95% CI -1.68-0.32),0.50 (95% CI 0.22-1.13), respectively; and there was no additive interaction among them. Conclusions:Elevated β 2-MG, KPS scores below 80, and elevated LDH are risk factors influencing incomplete remission for patients with DLBCL. The combined effect in patients with the combination of elevated LDH and KPS scores below 80 is lower than the single effect of the multiple of the both. There is a negative multiplicative interaction and no additive interaction in DLBCL patients with KPS scores below 80 and elevated LDH level.

Zinc levels are high in pancreatic β-cells, and zinc is involved in the synthesis, processing and secretion of insulin in these cells. However, precisely how cellular zinc homeostasis is regulated in pancreatic β-cells is poorly understood. By screening the expression of 14 Slc39a metal importer family member genes, we found that the zinc transporter Slc39a5 is significantly down-regulated in pancreatic β-cells in diabetic db/db mice, obese ob/ob mice and high-fat diet-fed mice. Moreover, β-cell-specific Slc39a5 knockout mice have impaired insulin secretion. In addition, Slc39a5-deficient pancreatic islets have reduced glucose tolerance accompanied by reduced expression of Pgc-1α and its downstream target gene Glut2. The down-regulation of Glut2 in Slc39a5-deficient islets was rescued using agonists of Sirt1, Pgc-1α and Ppar-γ. At the mechanistic level, we found that Slc39a5-mediated zinc influx induces Glut2 expression via Sirt1-mediated Pgc-1α activation. These findings suggest that Slc39a5 may serve as a possible therapeutic target for diabetes-related conditions.
