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.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Aim To study the effect of menthol on hypobaric hypoxia-induced pulmonary arterial hypertension and explore the underlying mechanism in mice. Methods 10 to 12 weeks old wild type (WT) mice and TRPM8 gene knockout (TRPM8

Objective To investigate the diagnostic value of combining carotid intima-media thickness (cIMT) with serum Galectin-3 (Gal-3) and Pentraxin 3 (PTX3) in patients with psoriasis complicated with cardiovascular disease (CVD). Methods Thirty-eight patients with psoriasis complicated with CVD were included in CVD group, 51 patients with psoriasis alone were included in psoriasis group, and 60 healthy subjects were selected as control group. Clinical data were collected from each group. The cIMT was measured using carotid ultrasound, and serum Gal-3, PTX3, and inflammatory markers[high sensitivity C-reactive protein (hs-CRP), procalcitonin (PCT), tumor necrosis factor-α (TNF-α)]were detected using enzyme-linked immunosorbent assay. Multivariate Logistic regression analysis was used to identify the influencing factors of CVD in patients with psoriasis. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of serum Gal-3, PTX3, and cIMT for CVD. Results The cIMT was greater in the CVD group and the psoriasis group than in the control group, and the CVD group was greater than the psoriasis group (P < 0.05). The serum levels of Gal-3, PTX3, hs-CRP, PCT, and TNF-α were higher in the CVD group and the psoriasis group than in the control group, and their levels were higher in the CVD group than in the psoriasis group (P < 0.05). The psoriasis area and severity index (PASI) score was higher in the CVD group than in the psoriasis group (P < 0.05). Pearson's correlation analysis showed that cIMT, Gal-3, and PTX3 were separately positively correlated with hs-CRP, PCT, and TNF-α (P < 0.05). Multivariate Logistic regression analysis showed that PASI score, cIMT, Gal-3, PTX3, hs-CRP, and TNF-α were independent influencing factors for CVD in patients with psoriasis (OR=1.250, 1.451, 1.432, 1.365, 1.413, 1.465; P < 0.05). The diagnostic model based on cIMT combined with serum Gal-3 and PTX3 had higher diagnostic value for CVD in patients with psoriasis than single diagnosis. The area under the curve was 0.922, with sensitivity and specificity of 0.91 and 0.85, respectively. Conclusion The cIMT, serum Gal-3, and serum PTX3 are independent influencing factors for CVD in patients with psoriasis. The combination of the three indicators has higher diagnostic value for CVD in patients with psoriasis.

The global COVID-19 coronavirus pandemic has infected over 109 million people, leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment. Here, we screened about 1.8 million small molecules against the main protease (M^pro) and papain like protease (PL^pro), two major proteases in severe acute respiratory syndrome-coronavirus 2 genome, and identified 1851M^pro inhibitors and 205 PL^pro inhibitors with low nmol/l activity of the best hits. Among these inhibitors, eight small molecules showed dual inhibition effects on both M^pro and PL^pro, exhibiting potential as better candidates for COVID-19 treatment. The best inhibitors of each protease were tested in antiviral assay, with over 40% of M^pro inhibitors and over 20% of PL^pro inhibitors showing high potency in viral inhibition with low cytotoxicity. The X-ray crystal structure of SARS-CoV-2 M^pro in complex with its potent inhibitor 4a was determined at 1.8 Å resolution. Together with docking assays, our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development.

We reported a case of a patient dignosed as tuberculosis and severe malnutrition with coronavirus disease 2019 （critical type） treated with a combination of Chinese medicine and Western medicine. Through the retrospective analysis of the diagnosis and treatment process of this patient， on the basis of Chinese medicine's understanding of the etiology and pathogenesis of “old state” and “deficient state”， the critical coronavirus pneumonia combined with pulmonary tuberculosis and severe malnutrition was mostly due to the physical condition and the invasion of epidemic toxin， resulting in dysfunctions of the internal organs such as the lungs， spleens， kidneys and other organs. Based on the understanding of the cause and mechanism of the coronavirus disease， the treatment combined Chinese and Western medical therapies was given. The western medicine was used with the main treatments of oxygen therapy， anti-viral， intestinal nutritional support， and anti-coagulation， while the Chinese medicine was used by tonifying qi， blood， yin， and yang， warming yang and dissipating cold， and clearing heat and dampness， then tonifying qi， nourishing yin and eliminating heat， in which tonifying middle and replenishing qi ran through the whole process. The integrated treatment eventually improved the patient's symptoms and accelerated the negative conversion of nucleic acid of the coronavirus.

Objective: Patients with advanced sarcomas have a dismal prognosis with few effective therapies. The purpose of this study was to evaluate the efficacy and safety of anlotinib in the treatment of advanced sarcoma and to explore the relationship between adverse events (AEs) and efficacy. Methods: Data from 45 advanced sarcoma patients who received anlotinib monotherapy at Affiliated Cancer Hospital of Zhengzhou University between June 2018 and August 2021 were retrospectively analyzed. According to Response Evaluation Criteria In Solid Tumors (RECIST) Version 1.1, the objective remission rate (ORR) and disease control rate (DCR) were calculated, and the progression free survival (PFS) and treatment-related AEs were recorded and analyzed. Survival analysis was conducted using the Kaplan-Meier survival rates were compared using the Log rank test. Results: Forty patients were treated for more than 1.5 months and received efficacy evaluation. The ORR and DCR after 3 months were 7.5%(3/40) and 80.0%(32/40), respectively. The overall ORR was 2.5%(1/40), the total DCR was 27.5%(11/40), and the median progression-free survival (m-PFS) was 6.70 months; The m-PFS of alveolar soft tissue sarcoma (ASPS) was 10.27 months, which was significantly longer than that of other subtypes of sarcoma (P=0.048). In addition, the DCR of ASPS and synovial sarcoma (SS) was significantly better than that of osteosarcoma (P<0.05). The most common AEs were elevated thyroid stimulating hormone (17.8%, 8/45), anemia (15.6%, 7/45), fatigue (11.1%, 5/45). Five patients developed grade 3 AEs after treatment; The PFS of patients with hand-foot syndrome after treatment was significantly longer than that of patients without hand-foot syndrome (14.10 vs 6.00, P=0.024). Conclusions: The efficacy of anlotinib in the treatment of ASPS and SS is better than that of other subtypes. The PFS in the group with hand-foot syndrome was significantly longer than that of the group without hand-foot syndrome.

Objective:To analyze the therapeutic effect of sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft of chronic calcaneal osteomyelitis.Methods:A retrospective analysis was peformed in 29 patients with chronic calcaneal osteomyelitis treated with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft in the Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from April 2013 to January 2020. There were 19 males and 10 females, with the age of (45.38±12.85) years, ranged from 22 to 67 years. The course of disease was (16.00±6.96) months, ranged from 6 to 36 months. The skin defect area was (41.9±15.9) cm 2, ranged from 11.8 to 86.8 cm 2. The causes of injury: 18 cases of high fall, 6 cases of traffic accidents, 3 cases of heavy rolling, the remaining 2 cases were machine strangulation and sharp stab wounds. The inflammatory markers [white blood cell (WBC), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), C reactive protein (CRP)] and bone healing time were recorded before operation, 2, 4, 8 weeks and 6 months after operation. During the follow-up period, the flap texture, survival were observed, and the ankle-posterior foot function recovery was evaluated by the American Association of Foot and Ankle Surgery (AOFAS) score were observed before and after the operation, and the incidence of complications were recorded. The measurement data were expressed as mean±standard deviation ( ± s), and the t-test was used for inter-group comparison; the levels of WBC, ESR, PCT and CRP at different time points before and after operation were compared by repeated measurement ANOVA, and the LSD t-test was used for pairwise comparison. Results:All the 29 patients were followed up for (14.51±6.10) months, ranged from 6 to 30 months. All the flaps survived without abrasion, ulceration, or skin protrusion, and all patients could walk normally with shoes. There were 28 cases of stage I bone healing, with an average of (5.87±2.07) months, ranged from 3 to 12 months. The inflammatory indexes was significantly decreased at different time points after operation ( P<0.05). There was no significant difference between 6 months and 8 weeks after operation ( P>0.05), while there was significant difference at other time points ( P<0.05). The ankle-posterior foot score of AOFAS at 6 months after treatment was significantly higher than that before treatment (83.44±7.93 vs 55.37±8.07), the differences was statistically significant ( P<0.05). The clinical efficacy of foot function recovery was excellent in 12 cases, good in 15 cases and fair in 2 cases among 29 patients .The excellent and good rate was 93.1% (27/29). One patient recurred 1 month after operation and was re-implanted with antibiotic-loaded calcium sulfate mixed autogenous iliac bone after debridement, no recurrence was found. The total complication rate was 31.0%, but there was no significant impact on the patient's life in the later period. All patients returned to daily life and work. Conclusion:The treatment of chronic calcaneal osteomyelitis with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft can effectively control infection, reconstruct calcaneal and soft tissue structure, promote functional recovery of affected limb, and ultimately improve the patient′s quality of life.

Objective:To investigate the effect of the production process of Zushima Guanjie Zhitong Gao from solvent method to hot-pressed method on in vitro kinetic behavior of this preparation. Method:Solvent and hot-pressed methods were used to prepare three batches of samples above pilot scale， and in vitro release and percutaneous penetration of the index components （7，8-dihydroxycoumarin and methyl salicylate） in Zushima Guanjie Zhitong Gao were investigated by modified Franz diffusing cells. Result:The contents of 7，8-dihydroxycoumarin and methyl salicylate in Zushima Guanjie Zhitong Gao prepared by solvent method were 73.72， 494.67 μg/patch， and their contents in hot-pressed method samples were 159.21， 2 638.99 μg/patch， respectively. In the solvent method samples， the average cumulative release amounts of 7，8-dihydroxycoumarin and methyl salicylate in 24 h were 2.04， 12.21 μg， and their average cumulative release amounts in 24 h of hot-pressed method samples were 2.16， 36.24 μg， respectively. In the solvent method samples， the average cumulative permeation amounts of 7，8-dihydroxycoumarin and methyl salicylate in 24 h were 0.38， 2.79 μg， and they were 0.40， 7.49 μg in hot-pressed method samples. The cumulative release and permeation amounts in 24 h of 7，8-dihydroxycoumarin in the hot-pressed method samples were basically the same as those of the solvent method samples， but the cumulative release and permeation amounts in 24 h of methyl salicylate in the hot-pressed method samples were significantly higher than those of the solvent method samples （P<0.05）. Conclusion:The retention of 7，8-dihydroxycoumarin and methyl salicylate by hot-pressed method is better than that of the solvent method. The process change has no significant effect on the in vitro kinetics of 7，8-dihydroxycoumarin in Zushima Guanjie Zhitong Gao， however， after the change from the solvent method to the hot-pressed method， the methyl salicylate in this preparation has a higher cumulative release and permeation amounts.
