Objective:To explore the impact of the two-way referral model on compliance and prognosis in patients with heart failure.Methods:This bidirectional cohort study enrolled chronic heart failure (CHF) patients treated at Qilu Hospital of Shandong University or designated primary hospitals between March 2018 and March 2022. Patients were categorized into two groups based on referral status: two-way referral group (participating in the referral model with≥1 follow-up visit at primary hospitals) and the core hospital group (receiving treatment and follow-up exclusively at Qilu Hospital). Baseline clinical characteristics were collected and compared between groups. Patients underwent followed-up, with primary endpoints including follow-up rate, drug (β-blockers, angiotension converting enzyme inhibitor (ACEI)/angiotensin Ⅱ receptor blockers (ARB)/angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose cotransporter 2 inhibitors and mineralocorticoid receptor antagonists) utilization rate and target dose achievement rate. Secondary endpoints encompassed changes from baseline in left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), and N-terminal pro-brain natriuretic peptide (NT-proBNP), plus cardiovascular mortality and heart failure rehospitalization. Generalized linear mixed models analyzed longitudinal trends in LVEF, LVEDd, and NT-proBNP levels. Kaplan-Meier curves and Cox regression evaluated LVEF recovery rates, supplemented by subgroup analyses. Multivariate logistic regression was used to identify factors influencing target dose achievement rate for β-blockers and ACEI/ARB/ARNI therapies in CHF patients.Results:A total of 357 patients were enrolled, aged 53 (41, 63) years, including 256 males (71.7%). 157 patients were in the two-way referral group and 200 patients in the core hospital-treated group. Compared with the core hospital-treated group, the two-way referral group had lower baseline LVEF (28 (22, 34)% vs. 31 (23, 36)%, P=0.021) and systolic blood pressure (116 (104, 125) mmHg vs. 121 (109, 134) mmHg (1 mmHg=0.133 kPa), P=0.010). The 12-month follow-up rate of the two-way referral group was higher than the core hospital-treated group (73.8% vs. 56.0%, P=0.004). No significant between-group differences were observed in drug utilization rate of β-blockers, ACEI/ARB/ARNI, or sodium-glucose cotransporter 2 inhibitors during follow-up (all P>0.05), while mineralocorticoid receptor antagonists use showed a declining trend in both groups. Although the core hospital-treated group had higher target dose achievement rates for β-blockers (65.4% vs. 49.3%, P=0.042) and ACEI/ARB/ARNI (79.8% vs. 65.8%, P=0.046) than the two-way referral group, multivariate logistic regression indicated that the two-way referral model was not a negative predictor for these outcomes (all P>0.05). Both groups showed improved NT-proBNP, LVEDd, and LVEF from baseline (all P<0.001) with no significant difference in trends between groups (all P>0.05). There was no significant difference in the composite incidence (7.6% vs. 6.5%, P=0.674) and cumulative incidence (log-rank P=0.684) of cardiovascular death and heart failure rehospitalization at 12 months between two groups. Conclusion:The two-way referral model demonstrates advantages in improving medication adherence, drug utilization rates, and targetdoseachievement rates among CHF patients. This model not only promotes cardiac functional recovery but also reduces risks of cardiovascular mortality and heart failure rehospitalization, achieving comparable therapeutic and management outcomes to those observed in core hospital-treated patients.

Objective:To observe the relationship between preoperative controlling nutritional status(CONUT)score and cognitive impairment,as well as short-term prognosis after intravenous thrombolysis(IVT)in patients with acute ischemic stroke(AIS).Methods:187 patients with AIS who were admitted to Shandong Provincial Third Hospital from January 2023 to May 2024 were selected,they were divided into non cognitive impairment group(n=106)and cognitive impairment group(n=81)based on whether cognitive impairment occurred,they were divided into poor prognosis group(n=58 cases)and good prognosis group(n=129 cases)according to the prognosis.Preoperative CONUT scores of patients with AIS for different cognitive impairments and prognoses were compared,correlation was analyzed by Spearman rank correlation,influencing factors were analyzed by multivariate logistic regression model.Results:Preoperative CONUT score in the cognitive impairment group was higher than that in the non cognitive impairment group(P＜0.05).Preoperative CONUT score in the poor prognosis group was higher than that in the good prognosis group(P＜0.05).Spearman rank correlation test results showed that,preoperative CONUT score was positively correlated with cognitive impairment and short-term prognosis after IVT(P＜0.05).Cognitive impairment were associated with age,concomitant hypertension,baseline national institutes of health stroke scale(NIHSS)score,and 25 hydroxyvitamin D3[25-(OH)2D3](P＜0.05).Age increase,concomitant hypertension,baseline NIHSS score increase,25-(OH)2D3 decrease,preoperative CONUT score increase were risk factors for cognitive impairment in patients with AIS(P＜0.05).Conclusion:Preoperative CONUT score increase is positively correlated with cognitive impairment and short-term prognosis after IVT.Meanwhile,age increase,concomitant hypertension,baseline NIHSS score increase,25-(OH)2D3 decrease,preoperative CONUT score increase are risk factors for cognitive impairment in patient with AIS.

Objective:To investigate the clinicopathological features of advanced-stage mycosis fungoides (MF).Methods:A retrospective case-series study was conducted. The clinical data of 5 cases diagnosed with advanced-stage MF in Chengdu Second People's Hospital between January 2015 and July 2023 were analyzed. The clinicopathological features of patients were summarized.Results:There were 2 males and 3 females in 5 MF patients, with the median age of 55 years (45-86 years) and the medical history of 2-16 years. The main symptoms were pruritus and erythema. The lesions were presented by erythema, scales, plaques, blisters, erosion, ulcers, pigmentation, nodules, and erythroderma. Histopathological examination showed different skin lesion patterns such as psoriasis-like, interfacial dermatitis, non-infectious granuloma, deep and shallow perivascular dermatitis, tumors. Among 5 patients, 1 case was mycosis fungoides bullosa, 2 cases were erythrodermic MF, 1 case was granulomatous MF, and 1 case was classical MF. Lymphocyte epidermis was found in 4 cases, cytoplasmic halos cells lined up along the basal layer of the epidermis and Pautrier microabscess were found in 3 cases, large-cell transformation was found in 1 case. Tumor cells were positive for CD3, CD4 and negative for CD8, CD56, ALK and CD20; EBER 1/2 hybridization in situ was negative. CD30 was positive in transformed large cells and T cell receptor gene rearrangement was positive. The tumor cells were detected in bone marrow and peripheral blood of 2 cases and in cerebrospinal fluid of 1 case. Head magnetic resonance imaging of 1 case indicated abnormal signal nodules in the right temporal region and the normal architecture of the lymph nodes in 2 cases was completed destroyed by malignant cells. TNMB stage: 2 cases were in stage Ⅱ B, 2 cases were in stage Ⅳ A2, and 1 case was in stage Ⅳ B. Interferon α-based systemic therapy was performed in 1 case, 2 cases received chemotherapy or combined with intrathecal injection and radiotherapy, and other 2 cases were not treated. All of them just achieved partial remission. Finally, 1 case died of sudden cardiac death, 2 cases died of lung infection, and 2 cases survived with tumors. Conclusions:Advanced-stage MF is presented with different skin lesion manifestations and histopathologic changes. Multidisciplinary combined management helps the diagnosis and treatment of MF.

Objective:To investigate GPRC5D expression on myeloma cells in newly diagnosed multiple myeloma (NDMM) patients and evaluate its prognostic significance.Methods:This study retrospectively analyzed the clinical data of 65 patients with NDMM treated at the Affiliated Hospital of Xuzhou Medical University from April 2023 to April 2024. The expression of GPRC5D on the surface of myeloma cells in all patients was detected with flow cytometry before induction therapy, and patients were stratified into high and low GPRC5D expression groups based on the median GPRC5D positivity rate. Clinical characteristics, immune status, treatment response after induction therapy, and prognosis were compared between the two groups.Results:The median positive rate of GPRC5D in the plasma cells of 65 patients with NDMM was 32.68%. Based on this threshold, patients were categorized into the high (33 cases, GPRC5D positive rate ≥ 32.68%) and low (32 cases, GPRC5D positive rate <32.68%) GPRC5D expression groups. Compared with the low GPRC5D expression group, the high GPRC5D expression group demonstrated a higher proportion of 1q21 gain (78.8% vs 43.8%, P=0.004), a higher incidence of immunoparesis involving ≥2 uninvolved immunoglobulins (87.9% vs 62.5%, P=0.018), and severe immunoparesis (59.4% vs 33.3%, P=0.046). Further, CD16 +CD56 + cell levels were lower in the high GPRC5D expression group [ (16.60±8.70) % vs (27.78±15.78) %, P=0.005]. No significant difference was observed in the overall response rate between the high and low GPRC5D expression groups (78.8% vs 93.8%, P=0.165). However, the high GPRC5D expression group exhibited a significantly lower rate of achieving very good partial remission or better (42.4% vs 78.2%, P=0.003) and a lower MRD negativity rate (30.0% vs 68.8%, P=0.002). Compared with the low GPRC5D expression group, patients with high expression demonstrated a significantly shorter median progression-free survival (11.2 months vs not reached, P=0.002), whereas the median overall survival was not reached in either group, with no statistically significant difference ( P=0.069) . Conclusions:The GPRC5D positivity rate in the plasma cells of patients with NDMM is associated with 1q21 gain and immune status. High GPRC5D expression at diagnosis may predict poor response to induction therapy and an unfavorable prognosis.

Objective: To investigate the influencing factors for anxiety symptoms among human papilloma virus (HPV)-infected women, so as to provide the evidence to improve the mental health of HPV-infected women. Methods: HPV-infected women visiting the gynecology department of a tertiary hospital in Urumqi from September to December 2024 were selected using a convenience sampling method. Basic information of HPV-infected women and information related to HPV infection were collected through a self-designed questionnaire. Anxiety symptoms was assessed by using the Generalized Anxiety Disorder-7 (GAD-7), with a GAD-7 score of ≥5 determined to be the presence of anxiety symptoms. Factors affecting anxiety symptoms in HPV-infected women were analyzed using a multivariable logistic regression model. Results: A total of 436 HPV-infected women were investigated. Among them, 361 (82.80%) were aged 30-<60 years old, 286 (65.60%) had a high school/technical secondary school or above, 361 (82.80%) had a spouse, 389 (89.22%) had given birth, and 234 (53.67%) had a family monthly income of less than 5 000 yuan. There were 90 HPV-infected women with multiple HPV infections, accounting for 20.64%. The sexual life of 155 people was affected, accounting for 35.55%. A total of 165 HPV-infected women with anxiety symptoms were detected, with a detection rate of 37.84%. Multivariable logistic regression analysis showed that multiple HPV infections (OR=1.776, 95%CI: 1.068-2.954), HPV infection time <3 months (OR=1.858, 95%CI: 1.132-3.050), lack of HPV-related knowledge (OR=1.742, 95%CI: 1.045-2.905), sexual life was affected (OR=3.480, 95%CI: 2.146-5.642), and monthly family income was less than 5 000 yuan (OR=1.815, 95%CI: 1.119-2.946) had a higher risk of anxiety symptoms Conclusions The detection rate of anxiety symptoms in HPV-infected women is high. The type of HPV infection, the duration of HPV infection, the understanding of HPV-related knowledge, the impact on sexual life, and the monthly family income are influencing factors of anxiety symptoms among HPV-infected women.

Aim To investigate the protective effects of resveratrol(RSV)on hypoxia/reoxygenation(H/R)-induced apoptosis in H9c2 cardiomyocytes and the un-derlying mechanisms.Methods A model of H/R was established in H9c2 cardiomyocytes.Cell apoptosis was determined by flow cytometry.The expressions of Bax,Bcl-2,cleaved caspase-3 and JAK2/STAT3 signa-ling pathway proteins were detected by Western blot.The inhibitor of JAK2,AG490,was used to assess the effect of RSV on H/R-induced apoptosis in H9c2 car-diomyocytes after inhibiting JAK2/STAT3 signaling pathway.Results RSV could effectively inhibit H/R-provoked cell apoptosis in H9c2 cardiomyocytes and increase the expression of p-JAK2 and p-STAT3.After AG490 intervention,the anti-apoptotic effect of RSV on H9c2 cardiomyocytes caused by H/R was significantly counteracted.Conclusions RSV can inhibit H/R-in-duced apoptosis in H9c2 cardiomyocytes through the activation of JAK2/STAT3 signaling pathway.

OBJECTIVE: To explore the mechanism of colon dialysis with Yishen Decoction (YS) in improving the autophagy disorder of intestinal epithelial cells in chronic renal failure (CRF) in vivo and in vitro. METHODS: Thirty male SD rats were randomly divided into normal, CRF, and colonic dialysis with YS groups by a random number table method (n=10). The CRF model was established by orally gavage of adenine 200 mg/(kg•d) for 4 weeks. CRF rats in the YS group were treated with colonic dialysis using YS 20 g/(kg•d) for 14 consecutive days. The serum creatinine (SCr) and urea nitrogen (BUN) levels were detected by enzyme-linked immunosorbent assay. Pathological changes of kidney and colon tissues were observed by hematoxylin and eosin staining. Autophagosome changes in colonic epithelial cells was observed with electron microscopy. In vitro experiments, human colon cancer epithelial cells (T84) were cultured and divided into normal, urea model (74U), YS colon dialysis, autophagy activator rapamycin (Ra), autophagy inhibitor 3-methyladenine (3-MA), and SIRT1 activator resveratrol (Re) groups. RT-PCR and Western blot were used to detect the mRNA and protein expressions of zonula occludens-1 (ZO-1), Claudin-1, silent information regulator sirtuin 1 (SIRT1), LC3, and Beclin-1 both in vitro and in vivo. RESULTS: Colonic dialysis with YS decreased SCr and BUN levels in CRF rats (P<0.05), and alleviated the pathological changes of renal and colon tissues. Expressions of SIRT1, ZO-1, Claudin-1, Beclin-1, and LC3II/I were increased in the YS group compared with the CRF group in vivo (P<0.05). In in vitro study, compared with normal group, the expressions of SIRT1, ZO-1, and Claudin-1 were decreased, and expressions of Beclin-1, and LC3II/I were increased in the 74U group (P<0.05). Compared with the 74U group, expressions of SIRT1, ZO-1, and Claudin-1 were increased, whereas Beclin-1, and LC3II/I were decreased in the YS group (P<0.05). The treatment of 3-MA and rapamycin regulated autophagy and the expression of SIRT1. SIRT1 activator intervention up-regulated autophagy as well as the expressions of ZO-1 and Claudin-1 compared with the 74U group (P<0.05). CONCLUSION Colonic dialysis with YS could improve autophagy disorder and repair CRF intestinal mucosal barrier injury by regulating SIRT1 expression in intestinal epithelial cells.

OBJECTIVE: Exposure to polycyclic aromatic hydrocarbons (PAHs) or metal(loid)s individually has been associated with neural tube defects (NTDs). However, the impacts of PAH and metal(loid) co-exposure and potential interaction effects on NTD risk remain unclear. We conducted a case-control study in China among population with a high prevalence of NTDs to investigate the combined effects of PAH and metal(loid) exposures on the risk of NTD. METHODS: Cases included 80 women who gave birth to offspring with NTDs, whereas controls were 50 women who delivered infants with no congenital malformations. We analyzed the levels of placental PAHs using gas chromatography and mass spectrometry, PAH-DNA adducts with ³²P-post-labeling method, and metal(loid)s with an inductively coupled plasma mass spectrometer. Unconditional logistic regression was employed to estimate the associations between individual exposures and NTDs. Least absolute shrinkage and selection operator (LASSO) penalized regression models were used to select a subset of exposures, while additive interaction models were used to identify interaction effects. RESULTS: In the single-exposure models, we found that eight PAHs, PAH-DNA adducts, and 28 metal(loid)s were associated with NTDs. Pyrene, selenium, molybdenum, cadmium, uranium, and rubidium were selected through LASSO regression and were statistically associated with NTDs in the multiple-exposure models. Women with high levels of pyrene and molybdenum or pyrene and selenium exhibited significantly increased risk of having offspring with NTDs, indicating that these combinations may have synergistic effects on the risk of NTDs. CONCLUSION Our findings suggest that individual PAHs and metal(loid)s, as well as their interactions, may be associated with the risk of NTDs, which warrants further investigation.

OBJECTIVE: This study aimed to investigate the prevalence of HIV pretreatment drug resistance (PDR) and the transmission clusters associated with PDR-related mutations in newly diagnosed, treatment-naive patients between 2020 and 2023 in Dehong prefecture, Yunnan province, China. METHODS: Demographic information and plasma samples were collected from study participants. PDR was assessed using the Stanford HIV Drug Resistance Database. The Tamura-Nei 93 model within HIV-TRACE was employed to compute pairwise matches with a genetic distance of 0.015 substitutions per site. RESULTS: Among 948 treatment-naive individuals with eligible sequences, 36 HIV subtypes were identified, with unique recombinant forms (URFs) being the most prevalent (18.8%, 178/948). The overall prevalence of PDR was 12.4% (118/948), and resistance to non-nucleotide reverse transcriptase inhibitors (NNRTIs), nucleotide reverse transcriptase inhibitors (NRTIs), and protease inhibitors (PIs) was 10.7%, 1.3%, and 1.6%, respectively. A total of 91 clusters were identified, among which eight showed evidence of PDR strain transmission. The largest PDR-associated cluster consisted of six CRF01_AE drug-resistant strains carrying K103N and V179T mutations; five of these individuals had initial CD4+ cell counts < 200 cells/μL. CONCLUSION The distribution of HIV subtypes in Dehong is diverse and complex. PDR was moderately prevalent (12.4%) between 2020 and 2023. Evidence of transmission of CRF01_AE strains carrying K103N and V179T mutations was found. Routine surveillance of PDR and the strengthening of control measures are essential to limit the spread of drug-resistance HIV strains.
