ObjectiveTo compare the clinical features of patients with hepatitis B virus （HBV）-related early-onset liver cancer and those with late-onset liver cancer， to assess the severity of the disease， and to provide a theoretical basis for the early diagnosis and treatment of liver cancer. MethodsA retrospective analysis was performed for 695 patients who were diagnosed with HBV-related liver cancer for the first time in Guangzhou Eighth People’s Hospital， Guangzhou Medical University， from January 2019 to August 2023， among whom 93 had early-onset liver cancer （defined as an age of50 years for female patients and40 years for male patients） and 602 had late-onset liver cancer （defined as an age of ≥50 years for female patients and ≥40 years for male patients）. Related clinical data were collected， including demographic data， clinical symptoms at initial diagnosis， comorbidities， smoking history， drinking history， family history， routine blood test results， biochemical parameters of liver function， serum alpha-fetoprotein（AFP）， virological indicators， coagulation function， and imaging findings. The pan-inflammatory indices neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， and lymphocyte-to-monocyte ratio （LMR） were calculated， as well as FIB-4 index， aspartate aminotransferase-to-platelet ratio index （APRI）， S index， Model for End-Stage Liver Disease （MELD） score， Child-Turcotte-Pugh （CTP） score， albumin-bilirubin （AIBL） grade， and Barcelona Clinic Liver Cancer （BCLC） stage. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or Fisher’s exact test were used for comparison of categorical data between two groups. ResultsThere were significant differences between the two groups in the proportion of male patients and the incidence rates of diabetes， hypertension， and fatty liver disease （χ²=6.357， 15.230， 11.467， and 14.204， all P0.05）， and compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly higher proportion of patients progressing to liver cancer without underlying cirrhosis （χ²=24.657， P0.001） and a significantly higher proportion of patients with advanced BCLC stage （χ²=6.172， P=0.046）. For the overall population， the most common clinical symptoms included abdominal distension， abdominal pain， poor appetite， weakness， a reduction in body weight， edema of both lower limbs， jaundice， yellow urine， and nausea， and 55 patients （7.9%） had no obvious symptoms at the time of diagnosis and were found to have liver cancer by routine reexamination， physical examination suggesting an increase in AFP， or radiological examination indicating hepatic space-occupying lesion； compared with the late-onset liver cancer group， the patients in the early-onset liver cancer group were more likely to have the symptoms of abdominal distension， abdominal pain， and jaundice （all P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly larger tumor diameter （Z=2.845， P=0.034）， with higher prevalence rates of multiple tumors and intrahepatic， perihepatic， or distant metastasis （χ²=5.889 and 4.079， both P0.05）， and there were significant differences between the two groups in tumor location and size （χ²=3.948 and 11.317， both P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had significantly lower FIB-4 index， proportion of patients with HBsAg ≤1 500 IU/mL， and levels of LMR and Cr （all P0.05）， as well as significantly higher positive rate of HBeAg and levels of log₁₀ HBV DNA， AFP， WBC， Hb， PLT， NLR， PLR， TBil， ALT， Alb， and TC （all P0.05）. ConclusionCompared with late-onset liver cancer， patients with early-onset liver cancer tend to develop liver cancer without liver cirrhosis and have multiple tumors， obvious clinical symptoms， and advanced BCLC stage， which indicates a poor prognosis.

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.

OBJECTIVES: Verrucous epidermal nevus (VEN), seborrheic keratosis (SK), verruca plana (VP), verruca vulgaris (VV), and nevus sebaceous (NS) are common verrucous proliferative skin diseases with similar clinical appearances, often posing diagnostic challenges. Dermoscopy and reflectance confocal microscopy (RCM) can aid in their differentiation, yet their specific features under these tools have not been systematically described. This study aims to summarize and analyze the dermoscopic and RCM features of VEN, SK, VP, VV, and NS. METHODS: A total of 121 patients with histopathologically confirmed verrucous proliferative skin diseases were enrolled. Dermoscopy and RCM imaging was used to observe and analyze the microscopic features of these conditions. RESULTS: Under dermoscopy, the 5 diseases displayed distinct characteristics: VEN typically showed gyriform structures; SK was characterized by gyriform structures, comedo-like openings, and milia-like cysts; VP and VV featured dotted vessels and frogspawn-like structures; NS presented as brownish-yellow globules. RCM revealed shared features such as hyperkeratosis and acanthosis across all 5 diseases. Specific features included gyriform structures and elongated rete ridges in VEN; pseudocysts and gyriform structures in SK; evenly distributed ring-like structures in VP; vacuolated cells and papillomatous proliferation in VV; and frogspawn-like structures in NS. CONCLUSIONS These 5 verrucous proliferative skin conditions exhibit distinguishable features under both dermoscopy and RCM. The combination of these 2 noninvasive imaging modalities holds significant clinical value for the differential diagnosis of verrucous proliferative skin diseases.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Gene therapy, harnessing the power of CRISPR-Cas9 and/or DNAzyme systems, stands as a pivotal approach in cancer therapy, enabling the meticulous manipulation of genes pivotal to tumorigenesis and immunity. However, the pursuit of precise gene therapy encounters formidable hurdles. Herein, a near-infrared upconversion theranostic nanomachine is devised and tailors for CRISPR-Cas9/DNAzyme systems mediate precise gene therapy. An ingenious logic DNAzyme system consists of Chain 1 (C1)/Chain 2 (C2) and endogenous lncRNA is designed. We employ manganese modified upconversion nanoparticles for carrying ultraviolet-responsive C1-PC linker-C2 (C₂P) chain and Cas9 ribonucleoprotein (RNP), with outermost coats with hyaluronic acid. Upon reaching tumor microenvironment (TME), the released Mn²⁺ ions orchestrate a trifecta: facilitating endosomal escape, activating cGAS-STING signaling, and enabling T1-magnetic resonance imaging. Under near-infrared irradiation, Cas9 RNP/C₂P complex dissociates, releasing Cas9 RNP into the nucleus to perform gene editing of Ptpn2, while C1/C2 chains self-assemble with endogenous lncRNA to form a functional DNAzyme system, targeting PD-L1 mRNA for gene silencing. This strategy remodels the TME by activating cGAS-STING signaling and dual immune checkpoints blockade, thus realizing tumor elimination. Our theranostic nanomachine armed with the CRISPR-Cas9/DNAzyme logic systems, represents a resourceful and promising strategy for advancing cancer systemic immunotherapy and precise gene therapy.

Objective:To observe the efficacy and safety of combined lienal polypeptide injection therapy in the treatment of Mycoplasma pneumoniae pneumonia（MPP）in children aged 3 to 14 years old in multiple clinical centers.Methods:A randomized，controlled，multi-center clinical study design was adopted.A total of 240 hospitalized children aged 3 to 14 years old with MPP from 7 hospitals from September 1，2023 to January 31，2024 were included.According to the severity of pneumonia，they were divided into the mild MPP group with 80 cases and the severe MPP/refractory MPP（SMPP/RMPP）group with 160 cases，and then randomly divided into the control group and the experimental group at a ratio of 1 ∶1，using the random number table method.After screening，subjects entered a treatment period of 5 to 7 days.The control group was treated with azithromycin，while the experimental group was treated with azithromycin plus lienal polypeptide injection .The recovery of lung CT，length of hospital stay，duration of fever，cough score，whether mild cases developed into severe or refractory cases，duration of hormone use，use of intravenous immunoglobulin（IVIG），bronchoscopy treatment，and immune function were observed between the two groups to evaluate the efficacy of lienal polypeptide injection.Adverse events after medication，vital signs，blood routine，urine routine，liver function，myocardial enzymes，renal function，and electrocardiogram were observed to evaluate the safety. Results:A total of 231 subjects have completed the trial in the 7 hospitals，including 118 cases in the experimental group and 113 cases in the control group.Main observation index：the rate of lung CT aggravation in the experimental group was lower than that in the control group（2.6% vs 15.3%， P<0.01），and the difference was statistically significant.Secondary indexes：there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.However，the rate of cases of plastic bronchitis（PB）found under bronchoscopy in the experimental group was lower than that in the control group（0 vs 18.8%， P=0.03），and the difference was statistically significant.Among the mild MPP（72 cases），there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and the improvement rate of lung CT between the two groups（all P>0.05）.However，compared with the control group，the rate of cases developing into SMPP/RMPP in the experimental group was less（24.3% vs 48.6%， P=0.03），and the difference in IgG before and after treatment was small［0.53（-0.04，1.18）g/L vs 1.33（0.48，2.25）g/L， P=0.01］.Among the SMPP/RMPP cases（159 cases），the rate of cases of PB found under bronchoscopy in the experimental group was less than that in the control group（0 vs 20%， P=0.04），and the rate of cases with aggravated lung CT in the experimental group was less than that in the control group（1.3% vs 19.5%， P<0.01），and the improvement rate of lung CT in the experimental group was higher than that in the control group（88.8% vs 75.3%， P=0.03），with statistically significant differences.There were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.Two cases in the experimental group developed rashes，which improved after the drug was discontinued.There were no serious adverse reactions such as abnormal vital signs like dyspnea and cyanosis due to the use of lienal polypeptide injection.There were no obvious changes in blood routine，liver function，myocardial enzymes，renal function，electrocardiogram，and urine routine values before and after medication compared with the baseline. Conclusion:The combined use of lienal polypeptide injection in the treatment of MPP in children can reduce the probability of the transformation from mild cases to SMPP/RMPP，reduce the rate of aggravation of the image findings，promote the absorption of lung inflammation，reduce the rate of PB found under bronchoscopy，and has good safety.

Objective To explore the diagnostic value of serum sex hormone binding globulin(SHBG),in-sulin-like growth factor-1(IGF-1)and bone age index(BAI)in girls with precocious puberty(PP).Methods A total of 220 girls with PP who were treated in this hospital from January 2022 to August 2024 were selected as the research subjects.The research subjects were divided into 104 children with central preco-cious puberty(CPP,CPP group)and 116 children with simple premature thelarche(SPT,SPT group)accord-ing to the type of the patients' disease.Another 110 girls with normal physical examination and development during the same period were selected as the control group.The levels of serum SHBG and IGF-1 in each group were determined and BAI was calculated.The diagnostic efficacy of the combined detection of serum SHBG,IGF-1 and BAI for CPP was analyzed through the receiver operating characteristic curve,and the correlation between serum SHBG,IGF-1,BAI and sex hormone indicators in girls with PP was analyzed by Pearson corre-lation analysis.Results The levels of height,basal follicle-stimulating hormone(FSH),basal luteinizing hor-mone(LH),and estradiol(E2)in the CPP group and the SPT group were higher than those in the control group,and the differences were statistically significant(P＜0.05).The serum SHBG levels in the CPP group and the SPT group were lower than those in the control group,and the differences were statistically significant(P＜0.05).The serum IGF-1 and BAI in the CPP group and the SPT group were higher than those in the control group,and the differences were statistically significant(P＜0.05).The area under the curve(AUC)of the three combined diagnoses of PP in girls was 0.941,which was significantly larger than those of IGF-1 and BAI(Z=8.140,9.470,both P＜0.05).The AUC of the three combined diagnoses of CPP in girls was 0.958,which was significantly higher than those of the single tests of serum SHBG,IGF-1,and BAI(Z=2.821,7.363,6.412,all P＜0.05).The levels of serum SHBG in PP of girls were negatively correlated with those of IGF-1,BAI,basal FSH,basal LH and E2(P＜0.05).Serum IGF-1 was positively correlated with BAI,basal FSH and basal LH(P＜0.05),but not correlated with E2(P＞0.05).BAI was positively correla-ted with the levels of basal FSH,basal LH and E2(P＜0.05).Conclusion The combination of serum SHBG and IGF-1 with BAI has certain diagnostic value for PP in girls,especially for the diagnosis of CPP,which is significantly superior to a single test.

Objective To explore the perioperative safety of video-assisted thoracic surgery (VATS) in Day Care Unit and the risk factors for delayed discharge under centralized management model. Methods The patients with VATS managed by the Day Care Unit of the Drum Tower Hospital Affiliated to Nanjing University Medical School in 2021 were retrospectively collected. The patients’ postoperative data and risk factors for delayed discharge were analyzed. Results A total of 383 patients were enrolled, including 179 males and 204 females with an average age of 46.09±14.82 years. Eleven (2.87%) patients developed grade 3-4 postoperative complications during the hospitalization. Eighteen (4.70%) patients visited unscheduled outpatient clinic within 7 days, and 6 (1.57%) patients were re-hospitalized within 30 days after discharge. The remaining patients had no significant adverse events during the 30-day follow-up. The average length of hospital stay was 2.27±0.35 d. The length of hospital stay was over 48 h in 48 (12.53%) patients. The independent risk factor for delayed discharge was lobectomy or combined resection (OR=3.015, 95%CI 1.174-7.745, P=0.022). Conclusion VATS can be safely conducted under the centralized management in Day Care Unit. The risk factor for delayed discharge is the extent of surgical resection.

One of the most common and significant symptoms for skin disorders is pruritus.Additionally,it serves as a significant catalyst for the exacerbation or reoccurrence of skin diseases.Pruritus seriously affects patients'physical and mental health,and even the quality of life.It brings a heavy burden to the patients,the families,even the whole society.The pathogenesis and regulation mechanisms for pruritus are complicated and have not yet been elucidated.Previous clinical studies have shown that itch worsens at night in scabies,chronic pruritus,atopic dermatitis,and psoriasis,suggesting that skin pruritus may change with circadian rhythm.Cortisol,melatonin,core temperature,cytokines,and prostaglandins are the main regulatory factors of the circadian rhythm of pruritus.Recent studies have shown that some CLOCK genes,such as BMAL1,CLOCK,PER,and CRY,play an important role in the regulation of the circadian rhythm of pruritus by regulating the Janus tyrosine kinase(JAK)-signal transducer and activator of transcription(STAT)and nuclear factor kappa-B(NF-κB)signaling pathways.However,the mechanisms for circadian clock genes in regulation of circadian rhythm of pruritus have not been fully elucidated.Further studies on the mechanism of circadian clock genes in the regulation of circadian rhythm of pruritus will lay a foundation for elucidating the regulatory mechanisms for pruritus,and also provide new ideas for the control of pruritus and the alleviation of skin diseases.

Objective:Exploring the effect of recovery-oriented family psychoeducation on the level of social support and family resilience of patients with schizophrenia in remission stage, providing theoretical basis for clinical application.Methods:Using a randomized controlled trial method and convenience sampling method, 60 patients with schizophrenia in remission who visited the outpatient department of the Affiliated Mental Health Center of Shanghai Jiao Tong University School of Medicine from April 2020 to March 2022 were selected as the study subjects, and they were divided into experimental group and control group, with 30 patients in each group according to their residence places. The control group was given routine health education; the experimental group was given the rehabilitation oriented family psychoeducation, before intervention and 3 months after intervention, Social Support Rating Scale and Family Resilience Questionnaire were used to evaluate the intervention effect.Results:A total of 60 patients were included in the control group, including 13 males and 17 females, aged (27.0 ± 6.5)years.In the experimental group, there were 14 males and 16 females, aged (28.0 ± 5.6) years. After intervention, the scores of subjective support, objective support and social support utilization in Social Support Rating Scale of the experimental group were 14.33 ± 3.36, 8.43 ± 1.63 and 9.60 ± 2.49, respectively, the control group were 16.20 ± 3.83, 10.00 ± 2.59 and 8.33 ± 2.28, respectively, and the differences were statistically significant ( t=2.00, 2.80, -2.05, all P<0.05). After intervention, the total score of Family Resilience Questionnaire and the scores of perseverance, support and harmony were 78.77 ± 9.61, 24.90 ± 3.07, 15.10 ± 2.23 and 23.63 ± 3.04, respectively. Higher than the control group 72.67 ± 15.96, 23.43 ± 4.92, 14.03 ± 3.60, 21.13 ± 5.13, the differences were statistically significant ( t values were -2.29--1.37, all P<0.05). Conclusions:Recovery-oriented family psychoeducation can improve the level of social support and family resilience of schizophrenia patients in remission.
