After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.

Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.

Objective:To compare Al 18F-1, 4, 7-trizacyclononane-1, 4, 7-triacetic acid (NOTA)-fibroblast activation protein inhibitor (FAPI)-04 PET/CT with 18F-FDG PET/CT in the evaluation of patients with initial gastric cancer. Methods:Twenty patients (13 males, 7 females, age: 27-77 years) with histologically proven gastric cancer were recruited prospectively between March 2021 and July 2022 in the First Affiliated Hospital of Zhengzhou University. Each patient underwent both 18F-FDG and Al 18F-NOTA-FAPI-04 PET/CT within one week. SUV max, tumor background ratio (TBR) and positive detection rate of the two methods were compared (Wilcoxon signed rank sum test, McNemar χ2 test). Results:Al 18F-NOTA-FAPI-04 showed higher SUV max and TBR than those of 18F-FDG in primary tumors (10.2(8.0, 13.7) vs 5.2(3.3, 7.7), z=-3.47, P=0.001; 7.6(5.6, 10.3) vs 2.4(1.8, 3.0), z=-3.85, P<0.001). For the detection of primary gastric cancer, the positive detection rate of Al 18F-NOTA-FAPI-04 PET/CT showed the trend of being higher than that of 18F-FDG PET/CT (95%(19/20) and 75%(15/20); χ2=2.25, P=0.125). For assessing lymph node metastasis, the detection rate of Al 18F-NOTA-FAPI-04 PET/CT was higher than that of 18F-FDG PET/CT (78.9%(101/128) vs 64.8%(83/128); χ2=13.47, P<0.001). The SUV max and TBR of Al 18F-NOTA-FAPI-04 in lymph node were higher than those of 18F-FDG (5.3(3.5, 9.2) vs 2.8(1.8, 4.7), z=-7.31, P<0.001; 4.6(2.6, 6.5) vs 1.7(1.0, 3.0), z=-8.44, P<0.001). For the detection of peritoneal carcinomatosis, Al 18F-NOTA-FAPI-04 PET/CT showed higher peritoneal cancer index (PCI), SUV max, and TBR compared to 18F-FDG PET/CT (PCI: 12.0(3.0, 29.8) vs 5.5(0.5, 17.5), z=-2.22, P=0.026; SUV max: 8.2(4.4, 12.5) vs 2.7(1.9, 4.0); z=-2.52, P=0.012; TBR: 5.1(2.9, 13.3) vs 1.1(0.9, 2.0); z=-2.52, P=0.012). Conclusion:Al 18F-NOTA-FAPI-04 PET/CT outperforms 18F-FDG PET/CT in primary and metastatic lesions of gastric cancer and might be a potential novel modality for imaging patients with gastric cancer.

This article reported a case of fetal congenital pyriform sinus fistula (CPSF) diagnosed by prenatal ultrasound. An oval cystic mass in the left side of the fetal neck was detected during routine prenatal ultrasonography at 17 +2 weeks of gestation, which was also found in the systemic ultrasound screening at 23 weeks. Besides, a narrow fistula between the cyst and pharynx was observed in the coronal view of the neck, raising the suspicion of CPSF. On day 21 after birth, the cystic mass bulged out of the neck and the neonate started choking and coughing during feeding alongside wheezing respiration. Ultrasound examination showed a strong gas echo in the cystic mass, which was also confirmed by CT scan on day 25. On day 26, cystectomy, ligation of high fistula, and fistulectomy were performed, and the diagnosis of CPSF was confirmed. The baby recovered after the operation and was healthy during follow-up till three months.

Objective To analyze epidemiological characteristics and changing trends of common respiratory infectious diseases among 6-19 year-old population in Shenzhen from 2013 to 2021, and to provide a reference for prevention and control. Methods Data of influenza, mumps and varicella reported cases among the population aged 6-19 years in Shenzhen from 2013 to 2021 were collected, and descriptive methods and Joinpoint regression model were used to analyze epidemiological characteristics and trends of incidences. Results Between 2013 and 2022 in Shenzhen, the average annual incidence rates of influenza, mumps, and varicella among the population aged 6-19 years were 961.44/100 000, 157.70/100 000, and 664.34/100 000 respectively. The incidence of influenza showed an upward trend in 10 years, with an annual percent change (APC) of 52.88% (P<0.05). The incidence of mumps and varicella both showed an 'up-down' trend, with an inflection point in 2019. The incidence APC of mumps were 11.51% and -43.49%, respectively (P>0.05), while the incidence APC of varicella were 28.88% and -50.03%, respectively (P<0.05), respectively. From the point of seasonal distribution, the incidence of three infectious diseases all showed bimodal distribution, with peaks in winter (December to January of the following year) and at the turn from spring to summer (April to June). The proportion of reported cases of three infectious diseases among people aged 6-<10 years old exceeded 60%. The proportion of varicella cases among people aged 10-<15 and 15-19 was on the rise. The incidence rate of influenza and varicella in people aged 15-19 years increased fastest, with APCs of 77.89% and 33.00%, respectively (both P<0.05). Conclusions The trend analysis based on Joinpoint regression model displayed that the reported incidence of influenza among people aged 6-19 years in Shenzhen during 2013-2022 showed an upward trend, and the incidence of varicella had an 'up-down' trend. Children aged 6-<10 years old are the main incidence group, and the prevention and control of infectious diseases in primary schools should be further promoted. Meanwhile, the rapid rise in the incidence of respiratory infectious diseases among people aged 15-19 years old and the increase in the proportion of varicella cases among people aged 10-19 years old suggest that intervention should be carried out to address the influential factors such as immunization gaps and concentrated accommodation in the older age group of minors.

ObjectiveTo explore the effectiveness and safety of Yiqi Huoxue Formula (益气活血方, YHF) in the adjuvant treatment of chronic pulmonary heart disease (CPHD) and heart failure (HF)with qi deficiency and blood stasis pattern. MethodsOne hundred and twenty patients with CPHD and HF with qi deficiency and blood stasis pattern were allocated randomly into treatment group and control group, with 60 case in each group. The control group was given conventional basic western medicine, while the treatment group was given oral administration of YHF granules in addition, one dose per day. The treatment course for both groups was 8 weeks. The TCM symptom scores, Minnesota Life Quality Scale (MLHF-Q) scores, echocardiographic indicators including right ventricular end-diastolic diameter (RVEDD), left ventricular end-diastolic diameter (LVEDD), left atrial end-diastolic diameter (LAEDD) and pulmonary artery mean pressure (PAMP), six-minute walking distance (6MWD), and plasma N-terminal pro-B-type natriuretic peptide (NT-ProBNP) level were compared between the groups. The effectiveness regarding cardiac function and TCM syndromes were compared between the two groups after treatment, and the occurrence of adverse events was observed. ResultsWith two drop-outs both in the treatment group and control group, and 58 cases in each group were included in the outcome analysis. The total effective rate regarding cardiac function and TCM syndromes in the treatment group were 91.38% (53/58) and 96.55% (56/58), respectively, significantly higher than the corresponding 70.69% (41/58) and 48.27% (28/58) in the control group (P<0.05). After treatment, the TCM symptom scores and RVEDD level were significantly reduced in the treatment group, and MLHF-Q score, plasma NT-ProBNP level and PAMP level decreased significantly, while 6MWD increased in both groups (P<0.01). Compared to those in the control group, the TCM symptom scores, MLHF-Q score, plasma NT-ProBNP level and PAMP level significantly decreased, while 6MWD increased in the treatment group (P<0.01). There were no obvious abnormalities in the blood, urine, stool routine and liver and kidney function indicators in both groups. One adverse reaction each occurred in both groups, and there was no statistically significant difference in the incidence rates(P>0.05). ConclusionYHF combined with conventional western medicine can significantly improve the clinical efficacy, improve the clinical symptoms and cardiac function, increase the quality of life and exercise tolerance, and is relatively safe.

OBJECTIVE To explore the changes in chemical compositions and the characteristics of “fried charcoal and saving properties” based on the carbon-frying process of Sophora japonica and its bud. METHODS The slightly, moderately and heavily carbon-fried samples of S. japonica and its bud were prepared. The fingerprints of S. japonica, its bud and carbon-fried samples were established, and common peaks were identified. HPLC method was used to determine the contents of identified components and differential analysis was also performed; the differential components were screened by using chemometric methods, and their content ratios were used to characterize the “fried charcoal and saving properties” of S. japonica and its bud. RESULTS There were 9 common peaks in the fingerprints of S. japonica and its carbon-fried samples, 8 common peaks in those of S. japonica bud and its carbon-fried samples. In the fingerprints of S. japonica and its bud, and their different fried products, 6 components were identified, such as rutin, kaempferol-3-O-rutinoside, isorhamnetin-3-O-rutinoside, quercetin, kaempferol,isorhamnetin. Among them, the contents of rutin, kaempferol-3-O-rutinoside and isorhamnetin-3-O-rutinoside were the highest in slightly carbon-fried samples of S. japonica bud, and the contents of quercetin and isorhamnetin were the highest in moderately carbon-fried samples of S. japonica bud, and the contents of kaempferol were higher in moderately and healily carbon-fried samples of S. japonica bud. The chemometric results showed that the variable importance projection values of rutin and quercetin were both greater than 1. The range of rutin-quercetin content ratio between 9.00-14.00 and 3.00-6.00 respectively could characterize “fried charcoal and saving properties” of S. japonica and its bud. CONCLUSIONS There are significant differences in the chemical compositions of raw and fried products of S. japonica and its bud. Rutin and quercetin may be the differential components that affect their quality, and the ratio range of the two can be used to characterize the “fried charcoal and saving properties” of S. japonica and its bud in the future.

Objective:To investigate the clinical features, diagnosis and treatment of oblique vaginal septum syndrome (OVSS).Methods:The clinical data of 80 patients with OVSS admitted to The Second Hospital of Hebei Medical University from July 2005 to July 2023 were retrospectively analyzed. According to the classification system of OVSS proposed by Female Genital Anomalies Study Group, Chinese Obstetricians and Gynecologists Association in 2021, the patients were divided into four groups. The clinical manifestations, accompanied urinary system abnormalities, diagnosis and treatment methods and treatment outcomes were observed.Results:According to the above classification system, among the 80 patients with OVSS, 35 patients (44%, 35/80) were categorized as type Ⅰ, 33 patients (41%, 33/80) were categorized as type Ⅱ, 2 patients (3%, 2/80) were categorized as type Ⅲ and 10 patients (13%, 10/80) were categorized as type Ⅳ. The main onset symptom of patients was periodic abdominal pain (70%, 56/80), vaginal bleeding (20%, 16/80), dysuria or fecal impaction (15%, 12/80), vaginal mucopurulent discharge (10%, 8/80). The morbidity of combined urinary system abnormalities was 88% (70/80), and the most common urinary system abnormality was ipsilateral renal agenesis (81%, 65/80). Bilateral kidneys were normal in 13% (10/80) patients, and 6% (5/80) were combined with other urinary system abnormalities. A total of 74 patients underwent vaginal oblique septectomy or septum excision. Five of the 10 patients with type Ⅳ underwent hysterectomy on the cervical atresia side, 4 patients received hysteroscopy combined with cervicoplasty+oblique septotomy or septum excision, and one patient selected delayed menstruation. Two patients underwent laparoscopic resection of the dysplasia kidney and ectopic ureter which opening to the vagina. Eleven patients with endometriosis cyst, hydrosalpinx or empyema underwent laparoscopic surgery.Conclusions:The main symptom of type Ⅰ and Ⅳ patients is abdominal pain, while the main symptom of type Ⅱ and Ⅲ patients is bleeding. Magnetic resonance imaging (MRI) has advantages in the evaluation of complex OVSS, and MRI is recommended before operation to exclude other axial reproductive tract dysplasia and complex urinary system dysplasia. If there is leakage of urine, vaginal discharge or complex deformity, it is necessary to multidisciplinary discussion and formulate a reasonable surgical plan. The first treatment is related to the prognosis of patients especially children, and should be highly valued.

From June 16 to 30, 2023, men who have sex with men (MSM) who had visited Voluntary Counseling Testing (VCT) clinics in the Luohu, Futian and Nanshan districts of Shenzhen were included in this study to analyze their awareness of Mpox and the influencing factors. The mean age of the 262 MSM was (34.78±8.94) years, with the majority being unmarried (75.2%) and 79.0% confirmed to be infected with HIV. The awareness rates for five primary indicators, current status of Mpox, pathogen and source of infection, mode of transmission, population susceptibility, clinical manifestations and treatment were 68.4%, 84.7%, 60.3%, 87.8%, and 52.5%, respectively. The awareness rates for five secondary indicators, earliest transmission location (44.7%), main mode of transmission (54.2%), role of masks (46.9%), drug accessibility (46.6%), and self-limiting nature (38.2%) were all below 60%. The MSM population in Shenzhen perceived their likelihood of being infected (2.76±1.32) and discriminated against (3.87±1.26) as relatively low. The logistic analysis showed that the high school or vocational school education ( OR:3.094, 95 %CI:1.180-9.299), college or above education ( OR:5.360, 95% CI:2.159-15.501), and higher scores on questions affecting learning or work ( OR:2.196, 95% CI:1.409-3.599) were promoting factors for Mpox awareness, while higher scores on questions concerning the possibility of Mpox mortality ( OR:0.591, 95% CI:0.432-0.791) was the hindering factor for Mpox awareness.
