AIM: To investigate the changes of retinal nerve fiber layer(RNFL)thickness, retinal thickness and blood flow density in different stages of diabetic retinopathy(DR)patients based on optical coherence tomography angiography(OCTA).METHODS: A retrospective analysis was conducted on 382 patients(382 eyes)diagnosed with DR in our hospital from February 2023 to February 2024. According to the staging criteria, the patients were divided into mild group(n=121), moderate group(n=133), severe group(n=72), and proliferative group(n=56). The general clinical data of the four groups of patients was compared; OCTA was used to scan and collect data from all patients, and the RNFL thickness, retinal thickness, and blood flow density were compared among the four groups of patients.RESULTS: There was no statistically significant difference in age, gender, hypertension, chronic kidney disease, and random blood glucose among patients in the mild, moderate, severe, and proliferative groups(all P>0.05). As the stage of DR worsened, the duration of the disease gradually prolonged(P<0.05). The thickness of the RNFL(superior, inferior, temporal, nasal, and average thickness)and retinal thickness significantly increased with the severity of DR(all P<0.001); however, there was no statistically significant difference in inferior RNFL thickness between the moderate and mild groups(P>0.05). The blood flow density in the superficial and deep retinal layers, as well as in the choroidal capillary layer, significantly decreased with the progression of DR(all P<0.05). Nevertheless, there was no statistically significant difference in superficial retinal blood flow density between the moderate and severe groups(P>0.05).CONCLUSION: OCTA can accurately observe the changes in RNFL thickness, retinal thickness, and blood flow density in patients with DR at different stages, which can serve as sensitive indicators for monitoring DR progression.

BACKGROUND: High temperatures are known to be associated with an increased risk of self-harm, but the influence of demographic changes and country-level indicators on the burden of heat-related self-harm remains unclear. This study examined the key factors driving changes in self-harm mortality linked to high temperatures and explored their impact at the country level. METHODS: This is an ecological study that analyzes data from the 2021 Global Burden of Disease (GBD) study, the World Bank, and the Climate Research Unit (CRU) were analyzed. Decomposition analyses were used to identify key factors driving changes in high temperature-related self-harm mortality between 1990 and 2021. A panel data model assessed the impact of national indicators on heat-related self-harm mortality. RESULTS: In 2021, 14,885 deaths globally were attributed to heat-related self-harm, a 41.94% increase from 1990, with low-middle SDI regions accounting for 47.84% of these deaths. While the global death rate from heat-related self-harm declined slightly over this period, South Asia and low-middle SDI regions contributed most to the decline. However, population aging exacerbated mortality rates. Demographic and meteorological factors were also linked to heat-related self-harm. CONCLUSION The global decline in heat-related self-harm mortality is largely driven by reductions in females, low-middle SDI regions, and South Asia. However, population aging and growth in these regions have added to the mortality burden, slowing the overall decline. Factors such as population density are also associated with heat-related self-harm. Targeted measures are needed to mitigate heat-induced self-harm more effectively in future.

Objective To assess the efficacy and safety of ascending aorta banding technique combined with typeⅠhybrid aortic arch repair for the aortic arch diseases. Methods The clinical data of patients undergoing ascending aorta banding technique combined with type Ⅰ hybrid arch repair for aortic arch diseases from March 2019 to March 2022 in Beijing Anzhen Hospital were retrospectively analyzed. The technical success, perioperative complications and follow-up results were evaluated. Results A total of 44 patients were collected, including 35 males and 9 females, with a median age of 63.0 (57.5, 64.6) years. The average EuroSCORE Ⅱ score was 8.4%±0.7%. The technical success rate was 100.0%. All patients did not have retrograde type A aortic dissection and endoleaks. One patient died of multiple organ failure 5 days after operation, the in-hospital mortality rate was 2.3%, and the remaining 43 patients survived and were discharged from hospital. The median follow-up period was 14.5 (6-42) months with a follow-up rate of 100.0%. One patient with spinal cord injury died 2 years after hospital discharge. One patient underwent thoracic endovascular aortic repair at postoperative 3 months due to new entry tears near to the distal end of the stent. Conclusion Ascending aorta banding combined with typeⅠhybrid arch repair for the aortic arch diseases does not need cardio-pulmonary bypass. Ascending aorta banding technique strengthens the proximal anchoring area of the stent to avoid risks such as retrograde type A dissection, endoleak and migration. The operation owns small trauma, rapid recovery, low mortality and a low rate of reintervention, which may be considered as a safe and effective choice in the treatment of the elderly, high-risk patients with complex complications.

Objective To investigate the mechanism of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair in the treatment of hypertension based on the network pharmacology method and animal experiment verification.Methods(1)TCMSP,BATMAN and TCMIP databases were used to screen the active components and targets of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair.The hypertension-related targets were obtained by searching the Drugbank,Genecard,TTD and Disgenet databases.The intersection(common target)of the active component target and the target related to hypertension disease was taken,and the obtained intersection target was the potential target of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair for the treatment of hypertension.The active ingredients and their targets of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair were imported into Cytoscape 3.9.1 software to construct a'Chinese medicines-active ingredients-targets'network and screen key active ingredients.The protein-protein interaction(PPI)network of potential targets was constructed to screen potential core targets.The Metascape platform was used to analyze the GO function and KEGG pathway enrichment of potential targets.The key active components and potential core targets were selected for molecular docking verification.(2)Thirty male spontaneously hypertensive rats(SHR)were randomly divided into model group,western medicine group(Candesartan Cilexetil,0.72 mg·kg-1)and low-,medium-and high-dose groups of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma(2.25,4.50,9.00 g·kg-1).Another male WKY rats were selected as blank group,with 6 rats in each group,once a day for 8 weeks.The systolic blood pressure of rat tail artery was detected before administration and 2,4,6 and 8 weeks after drug intervention.The pathological changes of thoracic aorta were observed by HE staining.The protein expression levels of GRP78,CHOP and Caspase-12 in aorta abdominalis were detected by Western Blot.Results(1)A total of 83 active components of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma were obtained,and 158 potential targets(intersection targets)for the treatment of hypertension were screened out.Five key active ingredients:p-hydroxybenzoic acid,4-hydroxybenzylamine,tanshinone I,tanshinone,γ-sitosterol;6 potential core targets:IL6,TNF,CASP3,JUN,PTGS2,IL1B;GO functional enrichment analysis obtained 1 826 biological process items,89 cell component items,and 199 molecular function items.KEGG pathway enrichment analysis obtained 186 pathways,mainly involving neuroactive ligand-receptor interaction,calcium signaling pathway,inflammatory response(such as TNF and MAPK signaling pathway),vascular protection(such as HIF-1 and cAMP signaling pathway),oxidative stress(such as PI3K-Akt signaling pathway)and other signaling pathways.Tanshinone I and tanshinone had strong binding force to 6 potential core targets,and γ-sitosterol had strong binding force to IL6,CASP3,JUN,PTGS2 and IL1B.(2)Compared with the blank group,the systolic blood pressure of the model group was significantly increased(P＜0.01).The thoracic aortic endothelial injury was obvious,the endothelial cell morphology was abnormal,swelling and exfoliated cells could be seen,the intima of the tissue was disordered,the intima structure was incomplete,and the intima was thickened.The protein expressions of GRP78,CHOP and Caspase-12 in abdominal aorta were significantly increased(P＜0.01).Compared with the model group,the systolic blood pressure of the rats in the administration group was significantly decreased(P＜0.01);the injury of thoracic aorta was alleviated,and the morphology,intima structure and thickness of endothelial cells were improved to varying degrees.The protein expressions of GRP78,CHOP and Caspase-12 in abdominal aorta were significantly decreased(P＜0.01).Conclusion Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair may act on core targets such as IL6,TNF,CASP3,JUN,PTGS2,and IL1B through key active components such as p-hydroxybenzoic acid,tanshinone,and γ-sitosterol,and regulate key signaling pathways such as TNF signaling pathway,MAPK signaling pathway,PI3K-Akt signaling pathway,and PERK signaling pathway to improve vascular endothelial dysfunction,inhibit endoplasmic reticulum stress,and lower blood pressure.

Objective To investigate the effects of the Pingan qushi prescription on traditional Chinese medicine syndrome,adverse events,and compliance in young and middle-aged hypertensive patients.Methods One hundred thirty-two young and middle-aged patients with hypertension were selected and randomly divided into two groups.After elimination,64 cases were included in each group.For 2 months,the control group was treated with irbesartan tablets,and the observation group underwent the Pingan qushi prescription based on the control group.The blood pressure,curative effect,traditional Chinese medicine syndrome score,safety,adverse events,and prognosis-related indicators were compared between the two groups.Results The total effective rate of the observation group(96.88%,92.19%)was higher than that of the control group(82.52%,78.13%),and the difference was statistically significant(P = 0.005,P = 0.025).After 1 and 2 months of treatment,the blood pressure,syndrome scores,ALD,PRA,AngⅡ,and ET-1 in the observation group were lower than those in the control group,and the differences were statistically significant(all P<0.05).There was no sig-nificant difference in the incidence of adverse reactions between the two groups(P>0.05).There was no statistically significant difference(P>0.05)in the incidence of adverse events during treatment between the observation group(1.56%)and control group(10.94%).Conclusion The treatment of young and middle-aged community patients with hypertension undergoing the Pingan qushi pre-scription can further improve patients'symptoms,increase blood pressure control,promote prognosis improvement.

Objective To compare the clinical characteristics of cirrhosis with or without portal vein thrombosis(PVT),and to analyze the therapeutic effect of transjugular intrahepatic portosystemic shunt(TIPS)in treating cirrhosis with or without PVT.Methods The clinical data of 193 patients with cirrhosis complicated by gastrointestinal bleeding,who received TIPS from October 2018 to October 2022,were retrospectively analyzed.According to the presence or absence of PVT before TIPS,the patients were divided into non-PVT group(n=118)and PVT group(n=75).After TIPS,the patients were followed up at one,3,6 months and every 6 months thereafter.The effect of PVT on the clinical characteristics of cirrhosis patients and on the therapeutic efficacy after TIPS were analyzed.Results The success rate of TIPS was 100％in both groups.The proportion of carrying out splenectomy or partial splenic artery embolization(PSE)in PVT group was 26.7％(20/75),which was obviously higher than 13.6％(16/118)in non-PVT group,the difference between the two groups was statistically significant(x2=5.192,P=0.023).In PVT group the preoperative Child-Pugh score,the model of end-stage liver disease(MELD)score and serum sodium model of end-stage liver disease(MELD-Na+)score were(8.1±1.9)points,(9.2±8.0)pointsand(9.2±8.0)points respectively,which in non-PVT group were(7.4±1.9)points,(7.7±5.8)points and(7.7±5.8)points respectively,the differences between the two groups were statistically significant(all P＜0.05).The incidence of overt hepatic encephalopathy in PVT group was 33.3％(25/75),which was strikingly higher than 19.5％(23/118)in non-PVT group,the difference between the two groups was statistically significant(P=0.030).No statistically significant differences in postoperative survival rate,rebleeding rate and stent dysfunction rate existed between the two groups(all P＞0.05).Conclusion For the treatment of cirrhotic patients with PVT complicated by gastrointestinal bleeding,TIPS is clinically safe and effective.In cirrhotic patients with PVT,the worse the liver function is,the higher the incidence of overt hepatic encephalopathy after TIPS will be.

Objective To compare and analyze the clinical characteristics and efficacy of transjugular intrahepatic portosystemic shunt(TIPS)in the treatment of liver cirrhosis with different portal vein thrombosis(PVT)grades.Methods A retrospective analysis was performed on 75 patients with liver cirrhosis and gastrointestinal bleeding who received TIPS.According to the Yerdel scale of PVT,the patients were divided into type Ⅰ(34 cases),type Ⅱ(25 cases)and type Ⅲ(16 cases).The patients were followed up 1,3,6 months after TIPS and every 6 months thereafter to compare the clinical data and the efficacy of TIPS in three types of PVT patients.Results The success rate of TIPS in three types of patients was 100％.There were differences in platelet to lymphocyte ratio(PLR)and proportion of different Child-Pugh grades among the three types of patients(P＜0.05).After TIPS,portal vein pressure was decreased compared with that before TIPS(P＜0.001).However,there were no significant differences in postoperative survival rate,rebleeding rate,over hepatic encephalopathy rate,stent dysfunction rate,thrombus complete recanalization rate and thrombus recurrence rate(P＞0.05).Conclusion The success rate of TIPS in three types of patients is higher,and the portal vein pressure is decreased significantly after TIPS,but there are no significant differences in the postoperative efficacy.Although the implementation of TIPS in cirrhotic PVT patients is challenging,it is still worth the effort to reshape the portal vein for the benefit of patients.

Objective To explore the therapeutic efficacy of the Fuyang Tongluo therapy combined with conventional western medicine in elderly patients with heart failure due to coronary heart disease.Methods In this single-blind randomized controlled trial,96 elderly patients with coronary heart disease and heart failure were randomly divided into three groups,each consisting of 32 individuals.Control group A was treated with conventional western medicine(atorvastatin combined with metoprolol),control group B with Fuyang Tongluo therapy,and the observation group with Fuyang Tongluo therapy and conventional western medicine.The three groups were compared in terms of therapeutic efficacy and traditional Chinese medicine symptom points as well as blood interleukin(IL)-23 and IL-17 levels,left ventricular end-systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD),and left ventricular ejection fraction(LVEF)values before and after treatment.Results The total clinical efficacy rate in the observation group was 93.75%,which was significantly higher than those in control groups A(68.75%)and B(65.63%)(P<0.05).After 4 and 8 weeks of treatment,the primary and minor symptom scores,total symptom scores,LVESD,LVEDD,and IL-23 and IL-17 levels in the observation group were significantly lower than those in control groups A and B(P<0.05).Conclusion The combination of the Fuyang Tongluo therapy with conventional western medicine exhibited good therapeutic efficacy in elderly patients with coronary heart disease and heart failure.These effects were achieved by inhibiting excessive expression of the inflammatory axis factors IL-23 and IL-17 and promoting the recovery of cardiac function.
