BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective To summarize and analyze the clinical phenotypes,hereditary features and treatment and follow-up strategies of different hereditary pheochromocytoma/paragangliomas(PCC/PGL)and related syndromes.Methods Forty-four clinically diagnosed PCC/PGL patients admitted in our hospital from January 2000 to August 2022 were enrolled,and the clinical data of them and their family members were collected.Second-generation sequencing was performed on 43 patients for genetic detection,and Sanger sequencing was applied to verify the mutation of the probands and family members.Results There were 15 patients diagnosed with hereditary PCC/PGL,including 7 cases of von Hippel-Lindau(VHL)syndrome,3 cases of multiple endocrine neoplasia type 2(MEN2),and 5 cases of familial paraganglioma syndrome.Seven VHL syndrome families were diagnosed as VHL2A(c.500G＞A),VHL2B(c.239G＞T and c.444_457del),and VHL2C(c.293A＞G)according to their clinical manifestations.All probands received surgical treatment,and 2 cases of recurrent PCC and the patients with multiple renal cancer also received targeted therapy with sunitinib.Three MEN2 families carried c.1901G＞C,c.1832G＞A,and c.1901G＞A missense mutations,respectively,and were diagnosed with MEN2A clinically.All of them underwent adrenalectomy and thyroidectomy,including one for preventive thyroidectomy.Among the 5 familial paraganglioma syndrome families,4 patients carried SDHB mutations(SDHB:c.343C＞T,c.541-2A＞G,c.575G＞A,c.268C＞T)and 1 patient carried an SDHD mutation(SDHD:c.337_340del).Sporadic retroperitoneal PGL were most common.Conclusion More than 1/3 of PCC/PGL patients carry germline gene mutations,showing obvious genotype-phenotype correlation.Genetic diagnosis technology plays an important guidance role for clinical precision treatment and follow-up,and genetic counseling.

Objective:To observe the effect of Tongguan Liqiao(opening orifices)needling plus tongue pressure resistance feedback training in treating post-stroke deglutition disorders. Methods:A prospective randomized controlled trial was conducted.A total of 120 patients with post-stroke deglutition disorders were divided into a control group and an observation group using the random number table method,with 60 cases in each group.Both groups were treated with routine treatments.The control group was treated with additional tongue pressure resistance feedback training,and the observation group was treated with additional Tongguan Liqiao needling based on the same intervention in the control group.After 4 weeks of treatment,the clinical efficacy was evaluated,and the complications that occurred during treatment were summarized.The FUJISHIMA Ichiro food intake level scale(FILS)and the swallowing quality of life questionnaire(SWAL-QOL)were scored before treatment and after 4 weeks of treatment. Results:The total effective rate of the observation group was higher than that of the control group(P<0.05).After 4 weeks of treatment,the FILS and SWAL-QOL scores in both groups were higher than those before treatment,and the scores in the observation group were higher than those in the control group(P<0.05).There was no statistical difference in the complication occurrence between the two groups(P>0.05). Conclusion:On the basis of routine treatments,Tongguan Liqiao needling plus tongue pressure resistance feedback training has a better effect in the treatment of post-stroke deglutition disorders.This method can effectively improve the swallowing function of patients,improve the quality of life,and is safe.

Brain size abnormality is correlated with an increased frequency of autism spectrum disorder (ASD) in offspring. Genetic analysis indicates that heterozygous mutations of the WD repeat domain 62 (WDR62) are associated with ASD. However, biological evidence is still lacking. Our study showed that Wdr62 knockout (KO) led to reduced brain size with impaired learning and memory, as well as ASD-like behaviors in mice. Interestingly, Wdr62 Nex-cKO mice (depletion of WDR62 in differentiated neurons) had a largely normal brain size but with aberrant social interactions and repetitive behaviors. WDR62 regulated dendritic spinogenesis and excitatory synaptic transmission in cortical pyramidal neurons. Finally, we revealed that retinoic acid gavages significantly alleviated ASD-like behaviors in mice with WDR62 haploinsufficiency, probably by complementing the expression of ASD and synapse-related genes. Our findings provide a new perspective on the relationship between the microcephaly gene WDR62 and ASD etiology that will benefit clinical diagnosis and intervention of ASD.

As the National Health Commission changes the management of novel corona virus infection, the situation and preventive policies for controlling the epidemic have also entered a new stage in China. Perioperative care strategies for orthopedic trauma such as designated isolation and nucleic acid test screening have also been adjusted in the new stage. Based on the perioperative work experiences in the new stage of epidemic from the frontline anti-epidemic staff of orthopedics in domestic hospitals and combined with the literature and relevant evidence-based medical data in perioperative care of orthopedic trauma patients under the current anti-epidemic policies at home and abroad, Chinese Orthopedic Association and Chinese Society of Traumatology organized relevant experts to formulate the Guideline for clinical perioperative care of orthopedic trauma patients in the new stage of novel corona virus infection ( version 2023). The guideline summarized 16 recommendations from the aspects of preoperative diagnosis and treatment, infection prevention, emergency operation and postoperative management to systematically standardize the perioperative clinical pathways, diagnosis and treatment processes of orthopedic trauma in the new stage of novel corona virus infection, so as to provide a guidance and reference for hospitals at all levels to carry out relevant work in current epidemic control policies.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Objective:To investigate the protective effect and mechanism of hydroxysafflor yellow A (HSYA) on severe acute pancreatitis (SAP) related lung injury.Methods:Fifty mice were randomly (random number) divided into five groups: the sham-operated group, SAP group and different doses (20, 40 and 80 mg/kg) of HSYA pretreatment group. Mice were pretreated with HSYA 24 h before SAP induction, pancreatic and lung tissues were isolated for histopathological examination at 72 h after modeling, and bronchoalveolar lavage fluid (BALF) was collected for biochemical analysis. Results:Compared with the sham-operated group, serum amylase activity, lung injury pathological score and BALF protein concentration in the SAP group were significantly increased [(2120.44 ± 354.50) U/L vs. (226.72 ± 20.84) U/L; (6.91 ± 0.28) vs. (0.53±0.18); (2563.25±348.22) μg/mL vs. (345.62±56.35) μg/mL, all P<0.05]. Inflammatory factors tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels and myeloperoxidase (MPO) activity were increased [(120.5±14.25) pg/mL vs. (31.5±4.82) pg/mL; (214.72±10.62) pg/mL vs. (39.26±5.66) pg/mL; (4.52±0.34) U/mg vs. (1.03±0.17) U/mg]. Compared with the SAP group, HSYA pretreatment significantly attenuated SAP-related pancreatic and lung tissue damage and the activities of the inflammatory factors TNF-α, IL-6 and MPO in BALF. In addition, HSYA promoted the expression of the antioxidant protein heme oxygenase-1 and blocked the activation of the NF-κB signaling pathway. Conclusions:HSYA exerts anti-inflammatory and antioxidant activities to inhibit SAP-related lung injury, which indicated that HSYA may be a potential therapeutic drug for SAP-induced lung injury.

Objective:To investigate high mobility group protein 1(HMGB1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)levels and their clinical significance in elderly patients with viral pneumonia.Methods:One hundred and sixty elderly patients with viral pneumonia admitted to the Sixth Hospital Affiliated to Anhui Medical University were enrolled as research subjects.In addition, 40 elderly people who underwent regular physical examination were considered as the control group.Patients with viral pneumonia were divided into the low-risk group, middle-risk group and high-risk group according to CURB-65 scores and pneumonia severity index(PSI)scores.HMGB1, TNF-α and IL-6 levels were compared between different groups.The correlations of CURB-65 scores and PSI scores with HMGB1, TNF-α, IL-6 levels were analyzed.Multivariate Logistic regression analysis was used to examine influencing factors for the severity of viral pneumonia in elderly patients.Results:HMGB1, TNF-α and IL-6 levels were higher in research subjects than in the control group.As the severity of viral pneumonia increased, so did HMGB1, TNF-α and IL-6 levels(all P<0.05). HMGB1, TNF-α and IL-6 levels in the severe viral pneumonia group were significantly higher than those in the non-severe viral pneumonia group( P<0.05). HMGB1, TNF-α and IL-6 levels were positively correlated with CURB-65 scores and PSI scores(CURB-65 score: r=0.463, 0.392 and 0.497, P=0.015, 0.003 and 0.025; PSI score: r=0.596, 0.515 and 0.381, P=0.007, 0.011 and 0.009). HMGB1, TNF-α and IL-6 levels were influencing factors for the severity of viral pneumonia in elderly patients( OR=1.344, 1.422 and 1.351, P=0.006, 0.015 and 0.009). Conclusions:HMGB1, TNF-α and IL-6 levels are closely correlated with the severity of viral pneumonia and are helpful for early assessment of viral pneumonia.

Objective:To investigate the diagnostic performance of repeat biopsy 68Ga-PSMA PET/CT to distinguish between benign and malignant prostate disease. Methods:The clinical data and medical imaging of thirty-nine patients underwent repeat prostate biopsy were analyzed respectively in this study. The median age of patients was 65 years (range 46-81 years), the median PSA level was 11.0ng/ml (range 5.4-49.8 ng/ml), f/tPSA was 0.15(0.01-16.50)ng/ml, prostate volume was 43.80(7.79-108.63)ml, and PSA density was 0.24(0.09-2.31)ng/ml 2. All patients underwent pre-biopsy 68Ga-PSMA PET/CT and the standard transrectal ultrasound-guided systematic prostate biopsy. Based on the biopsy results, 68Ga-PSMA PET/CT images of all patients were visually and semi-quantitatively analyzed. By visual analysis, 68Ga-PSMA uptake in prostate was defined as focal, multimodal and inhomogeneous, and then the detection rate of prostate cancer in each subgroup was analyzed. The value of the ROC curve in the diagnosis of prostate cancer was analyzed based on the SUV max of prostate cancer(SUV max), tumor-to-normal-prostate background(SUV T/BGp)as semi-quantitative parameters of 68Ga-PSMA PET/CT. Results:Prostate cancer was detected in 18 patients (46.2%) and 12 patients (30.8%) had clinically significant disease. There were 11, 5 and 2 patients with prostate cancer respectively in men with a focal (12 patients), multifocal(7 patients) and inhomogeneous (20 patients) 68Ga-PSMA uptake. The ROC analysis revealed a SUV max 5.3 and SUV T/BGp1.8 as an optimal cut-off level to distinguish between non-prostate cancer and prostate cancer in 68Ga-PSMA PET/CT, the sensitivity and specificity were 100.0% and 85.7% for SUV max (AUC=0.979), 83.3% and 90.5% for SUV T/BGp (AUC=0.915). Conclusions:Pre-biopsy 68Ga-PSMA PET/CT could help to distinguish between benign and malignant prostate disease before repeat prostate biopsy and detect the foci of prostate cancer.

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.
