AIM: To investigate the mechanism of Hexue Mingmu Tablets(HXMMT)in improving diabetic retinopathy(DR)based on transcriptomics.METHODS: Zebrafish DR models were established by 3-day glucose induction(130 mmol/L)starting at 3 days post-fertilization(dpf). Larvae were randomized into four groups: control group(CG; aquaculture water), model group(MG; 130 mmol/L glucose), low-dose HXMMT treatment group(L-HX; 130 mmol/L glucose +7.5 mg/L HXMMT), and high-dose HXMMT treatment group(H-HX; 130 mmol/L glucose +75 mg/L HXMMT), with a 3-day intervention period until 6 dpf. The area and length of eyes, and body length of zebrafish were observed by stereomicroscopy, retinal morphology was observed by hematoxylin-eosin staining(HE), and retinal vessel diameter was observed under fluorescence microscope. Differentially expressed genes(DEGs)were identified by RNA-sequencing(RNA-seq)technology to further elucidate the molecular mechanism of HXMMT in improving DR in zebrafish, and the sequencing accuracy was validated through quantitative real-time polymerase chain reaction(qRT-PCR).RESULTS: HE staining demonstrated that the intervention with HXMMT significantly improved the disordered cell arrangement, widened gaps, and thickened inner nuclear layer(INL)in ganglion cell layer GCL); retinal vascular diameter quantification revealed that the retinal vessel diameter of the MG significantly increased compared with the CG, and it was significantly changed after the intervention of HXMMT, with significant efficacy in the H-HX(P<0.05); transcriptomics profiling identified 1 470 reversed DEGs, predominantly enriched in the AMPK signaling pathway, FoxO signaling pathway, retinal developmental processes, and tight junction regulation. Technical validation confirmed strong correlation between qRT-PCR and RNA-seq data(R2=0.8571, P<0.05).CONCLUSION: HXMMT may improve retinal vascular microcirculation disorders in DR by regulating core targets including vsx1, pde6c, arr3a, plk1, fbp1b, foxo1a, pcna, and cdk1, as well as synergistically modulating processes such as retinal development in camera-type eyes, visual perception, microtubule cytoskeletal organization, tight junctions, and the AMPK signaling pathway, Foxo signaling pathway.

OBJECTIVE: This study examines utilizes the advantages of machine learning algorithms to discern key determinants in prognosticate postoperative circulatory complications (PCCs) for older patients. METHODS: This secondary analysis of data from a randomized controlled trial involved 1,720 elderly participants in five tertiary hospitals in Beijing, China. Participants aged 60-90 years undergoing major non-cardiac surgery under general anesthesia. The primary outcome metric of the study was the occurrence of PCCs, according to the European Society of Cardiology and the European Society of Anaesthesiology diagnostic criteria. The analysis metrics contained 67 candidate variables, including baseline characteristics, laboratory tests, and scale assessments. RESULTS: Our feature selection process identified key variables that significantly impact patient outcomes, including the duration of ICU stay, surgery, and anesthesia; APACHE-II score; intraoperative average heart rate and blood loss; cumulative opioid use during surgery; patient age; VAS-Move-Median score on the 1st to 3rd day; Charlson comorbidity score; volumes of intraoperative plasma, crystalloid, and colloid fluids; cumulative red blood cell transfusion during surgery; and endotracheal intubation duration. Notably, our Random Forest model demonstrated exceptional performance with an accuracy of 0.9872. CONCLUSION We have developed and validated an algorithm for predicting PCCs in elderly patients by identifying key risk factors.

OBJECTIVES: To compare the efficacy of toric implantable collamer lens (Toric-ICL) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for myopia correction in patients with moderate to high myopia complicated with astigmatism. METHODS: We retrospectively collected data from 64 patients (aged 18-42 years) with moderate to high myopia complicated with astigmatism (128 eyes) undergoing either Toric-ICL (28 patients/56 eyes) or FS-LASIK (36 patients/72 eyes) at our department between January, 2019 and December, 2020. The changes of uncorrected distance visual acuity (UCVA), spherical equivalent (SE), mean astigmatism correction index (CI), corneal endothelial cell density (ECD) and intraocular pressure (IOP) following the procedures were compared between the two groups. RESULTS: In FS-LASIK group, all the eyes (72/72) achieved an UCVA≥1.0, similar to the rate in Toric-ICL group (55/56 eyes; P=0.2374). The postoperative SE was also comparable between FS-LASIK and Toric-ICL groups [0.43±0.06 D (range: -1.0 to 1.50 D) vs 0.38±0.05 D (range: -0.75 to 1.00 D); P=0.56]. The mean astigmatism CI was significantly higher in FS-LASIK group than in Toric-ICL group (0.8561 vs 0.7176; P<0.0001), and 88.89% of the eyes in FS-LASIK group and 69.64% in Toric-ICL group had postoperative astigmatism ≤0.50 D. No significant changes were observed in postoperative corneal ECD in FS-LASIK group, whereas ECD decreased significantly after the procedure in Toric-ICL group (P=0.0057). The patients undergoing Toric-ICL exhibited no significant changes of postoperative IOP, but the patients receiving FS-LASIK had significantly reduced IOP after the procedure (P<0.001). CONCLUSIONS Although the patients included in Toric-ICL group had higher myopia and astigmatism, Toric-ICL still showed better predictability and efficacy for astigmatic correction in Toric-ICL group. Toric-ICL is an effective and safe equivalent of FS-LASIK for correcting moderate myopia but can be more advantageous for correcting high myopia with astigmatism.

Objective To explore the effect of prominent cortical vein(PCV)sign on the clinical prognosis of patients undergoing endovascular recanalization for acute anterior circulation cerebral infarction.Methods A total of 102 patients with acute anterior circulation large-vessel occlusion in Zhongshan Municipal Hospital of Tradiontional Chinese Medicine from January 1,2020 to December 21,2022,who received endovascular recanalization,were enrolled in this study.The clinical data and radiographic materials were collected.According to whether PCV sign was present or not,the patients were divided into PCV group and non-PCV group.The clinical data were compared between the two groups.Logistic regression analysis was used to analyze the correlation between the postoperative 90-day mRS score and the occurrence of PCV.Results Compared with non-PCV group,in PCV group the incidence of atrial fibrillation was even higher,and the good rate of collateral compensation was even lower,and the postoperative(7±2)-day NIHSS score was even lower;the differences in above indexes between the two groups were statistically significant(all P＜0.05).Ninety days after treatment,the proportion of patients having modified Rankin Scale(mRS)score ≤2 points in the non-PCV group was 76.3％,which was higher than 58.6％in the PCV group,but the difference was not statistically significant(P=0.074).Logistic regression analysis indicated that a positive correlation existed between the presence of PCV sign and atrial fibrillation(OR=9.679,95％CI=1.264-74.364)and a negative correlation existed between the presence of PCV sign and good collateral compensation(OR=0.015,95％CI=0.033-0.331).No relationship existed between the postoperative 90-day good prognosis and the presence of preoperative PCV sign(OR=2.078,95％CI=0.680-6.348),but patient's age,preoperative intravenous thrombolysis were negatively correlated with the preoperative Alberta Stroke Program Early CT(ASPECT)score(P＜0.005).Conclusion In patients with anterior circulation acute ischemic stroke(AIS),the occurrence of PCV sign is associated with the impaired collateral compensation and atrial fibrillation,but its impact on the clinical outcomes of patients after receiving reperfusion therapy remains uncertain.PCV sign may be used as a potential evaluation indicator for inadequate cerebrovascular collateral compensation.

Objective To analyze the clinical value of rebabapide combined with famotidine in the treatment of postoperative ulcers in patients with early gastric cancer.Methods Postoperative ulcer patients with early gastric cancer were selected as the study objects,and were divided into control group and treatment group according to treatment plan using cohort method.Control group was orally treated with famotidine tablet 20 mg,bid;on the basis of the control group,the treatment group was orally treated with rebabapide capsule 0.1 g,tid,and both groups were treated for 4 weeks.The gastric mucosal morphological indexes,gastrointestinal hormone[vasoactive intestinal peptide(VIP),cholecystokinin(CCK),motilin(MTL),pepsinogen[pepsinogen Ⅰ(PG Ⅰ),pepsinogen Ⅱ(PG Ⅱ)]in the two groups were compared.Results There were 40 patients in the treatment group and control group.After treatment,the total clinical effective rate of the treatment group was 92.50％(37 cases/40 cases)and higher than that of the control group[75.00％(30 cases/40 cases)],and the difference was statistically significant(P＜0.05).After treatment,the scores of mucosal thickness in treatment group and control group were(0.22±0.08)and(0.51±0.10)points;the scores of inflammatory cell infiltration degree were(0.42±0.08)and(0.79±0.16)points;the scores of gland density were(0.80±0.12)and(1.16±0.27)points,respectively;mucosal morphology scores were 0.48±0.11 and 0.74±0.12;VIP were(16.78±2.49)and(19.46±3.02)ng·L-1;CCK were(55.38±58.47)and(71.48±10.38)ng·L-1,respectively;MTL were(82.19±14.52)and(97.68±11.58)pg·mL-1;PG Ⅰ were(168.74±17.42)and(136.78±15.44)ng·mL-1,respectively;PG Ⅱ were(16.42±2.50)and(20.58±3.79)ng·mL-1,respectively.Compared with control group,there were statistically significant differences in the above indexes in treatment groups(all P＜0.05).The incidence of adverse drug reactions in the treatment group was 15.00％(6 cases/40 cases)compared with 10.00％(4 cases/10 cases)in the control group,there was no statistical significance(P＞0.05).Conclusion Rebaptidine combined with famotidine is effective and safe in the treatment of postoperative ulcer patients with early gastric cancer.It can improve gastric mucosa morphological indexes,gastrointestinal hormones and pepsinogen.

Background:Following the short-term outbreak of coronavirus disease 2019(COVID-19)in December 2022 in China,clinical data on kidney transplant recipients(KTRs)with COVID-19 are lacking.Methods:We conducted a single-center retrospective study to describe the clinical features,complications,and mortality rates of hospitalized KTRs infected with COVID-19 between Dec.16,2022 and Jan.31,2023.The patients were followed up until Mar.31,2023.Results:A total of 324 KTRs with COVID-19 were included.The median age was 49 years.The median time between the onset of symptoms and admission was 13 d.Molnupiravir,azvudine,and nirmatrelvir/ritonavir were administered to 67(20.7%),11(3.4%),and 148(45.7%)patients,respectively.Twenty-nine(9.0%)patients were treated with more than one antiviral agent.Forty-eight(14.8%)patients were treated with tocilizumab and 53(16.4%)patients received baricitinib therapy.The acute kidney injury(AKI)occurred in 81(25.0%)patients and 39(12.0%)patients were admitted to intensive care units.Fungal infections were observed in 55(17.0%)patients.Fifty(15.4%)patients lost their graft.The 28-d mortality rate of patients was 9.0%and 42(13.0%)patients died by the end of follow-up.Multivariate Cox regression analysis identified that cerebrovascular disease,AKI incidence,interleukin(IL)-6 level of>6.8 pg/mL,daily dose of corticosteroids of>50 mg,and fungal infection were all associated with an increased risk of death for hospitalized patients.Conclusions:Our findings demonstrate that hospitalized KTRs with COVID-19 are at high risk of mortality.The administration of immunomodulators or the late application of antiviral drugs does not improve patient survival,while higher doses of corticosteroids may increase the death risk.

Objective To analyze the effect of endoscopic tumor resection by submucosal tunnel(STER)on recurrence in patients with submucosal tumors(SMT)around cardia.Methods A total of 92 patients with SMT around cardia were selected and divided into the treatment group(n=46)and the control group(n=46)using random number table method.The treatment group and the control group were treated with STER and endoscopic submucosal dissection(ESD),respectively,and both groups were followed up for 12 months after surgery.Periop-erative indexes,therapeutic effects,quality of life,sleep,inflammatory indexes,immune indexes before and 1 week after surgery,complications 1 week after surgery,recurrence 12 months after surgery were compared between the two groups.Results Compared with the control group,the surgery time of the treatment group was longer,the hospital stay was shorter and treatment cost were lower,and the stripping speed was faster(P＜0.05).Compared with before surgery,scores of Pittsburgh sleep Quality index(PSQI),serum levels of interleukin-8(IL-8),inter-leukin-6(IL-6),high-sensitive C-reactive protein(hs-CRP)and whole blood levels of CD8+decreased in the two groups 1 week after surgery,and the levels were lower in the treatment group(P＜0.05).Compared with the preoperative results,the levels of whole blood CD4+and CD4+/CD8+,scores of Quality of Life Core 46 Questionnaire(QLQ-C46),Karnofsky Score(KPS)were higher in the two groups 1 week after surgery,those in the treatment group was higher(P＜0.05).1 week after surgery,the complication rate of the two groups was lower in the treat-ment group(P＜0.05),and 12 months after surgery,the recurrence rate of the two groups was not statistically significant(P＞0.05).Conclusion STER treatment for SMT around cardia was highly effective,resulting in superior perioperative outcomes,enhanced life and sleep quality,reduced systemic inflammation,and bolstered immune function.Moreover,it significantly lowered the risk of complications without raising the rates of recurrence.

Crohn’s disease is a chronic intestinal inflammatory disorder of unknown etiology. Although the pharmacotherapies for Crohn’s disease are constantly updating, nutritional support and adjuvant therapies have recently gained more attention. Due to advancements in clinical nutrition, various clinical nutritional therapies are used to treat Crohn’s disease. Doctors treating inflammatory bowel disease can now offer several diets with more flexibility than ever. The Crohn’s disease exclusion diet is a widely used diet for patients with active Crohn’s disease. The Crohn’s disease exclusion diet requires both exclusion and inclusion. Periodic exclusion of harmful foods and inclusion of wholesome foods gradually improves a patient’s nutritional status. This article reviews the Crohn’s disease exclusion diet, including its structure, mechanisms, research findings, and clinical applications.

Objective To investigate the association between stress and primary headache in nursing staff and the methods for managing such headache. Methods A semi-structured questionnaire was used to conduct a hospital-based cross-sectional study among 225 nursing staff members in a grade A tertiary teaching hospital in Changchun, Jilin, China. A total of 32 items were measured, including basic information, headache-and stress-related questions, job satisfaction, and coping strategies. According to the International Headache Society criteria, headache patients with migraine or episodic tension-type headache （with attacks for less than 15 days a month） were included for analysis. The Student's t-test, a one-way analysis of variance, and the chi-square test were used for statistical analysis. Results Among the 210 respondents, 103 （48.9%） reported the experience of primary headache in the previous year, and 98 （46.7%） experienced episodic headache （less than 15 days a month）. Detailed neurological interviews of the latter group showed that 56 respondents （26.5%） had migraine, 28 （13.3%） had tension-type headache, 11 （5.2%） had a combination of migraine and tension-type headache, and 4 （1.9%） had headache due to other causes. There were no significant differences in demographic data between headache patients and non-headache patients, although there was a significant difference in self-reported sources of stress between the two groups （individual P values ranging from 0.021 to <0.001）. The patients with headache experienced greater job-related stress than the individuals without headache （P<0.001）. The nursing staff members with a younger age, less experience, an unmarried status, and a lower educational level tended to report higher levels of stress. Treatment methods for headaches included sleep, medication, rest, medical consultation, and psychological help. Nurses often used nonsteroidal anti-inflammatory drugs for pain relief. Conclusion The results show that work stress is associated with primary headache among nursing staff, and nurses seldom seek help at the early stage of the disease. Therefore, education on how to alleviate stress and cope with headache for nursing staff may help them provide better care to patients.
