ObjectiveTo investigate the mechanism of Zuogui Wan （ZGW） in improving ovarian inflammatory microenvironment and stemness of ovarian germline stem cells （OSCs） for treating ovarian aging via the cyclic guanosine monophosphate/adenosine monophosphate synthase （cGAS）/stimulator of interferon genes （STING） signaling pathway. MethodsForty C57BL/6 female mice were randomly divided into a blank group， a model group， a low-dose ZGW group （2.7 g·kg^-1）， a high-dose ZGW group （5.4 g·kg^-1）， and an estradiol valerate group （0.15 mg·kg^-1）， with 8 mice in each group. Except the blank group， all other groups received a single intraperitoneal injection of cyclophosphamide at 120 mg·kg^-1 to establish an ovarian aging mouse model. After successful modeling， each group was continuously administered for 4 weeks， once daily. The physiological status of the mice was observed， and the ovarian index was calculated. The estrus cycle of the mice was monitored. Hematoxylin-eosin （HE） staining was used to observe pathological changes in ovarian tissue. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum sex hormone levels. Serum inflammatory factors interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and mouse interleukin-6 （IL-6） levels were detected using kits. Western blot was used to detect the protein expression of ovarian cGAS， STING， p-STING， TANK-binding kinase 1 （TBK1）， p-TBK1， interferon-induced transmembrane protein 3 （Fragilis）， and Vasa homolog protein （MVH）. Quantitative real-time polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of inflammatory factors in ovarian tissue. Immunofluorescence double labeling was performed to locate OSCs in ovarian tissues， and fluorescence intensities of OSCs markers MVH and octamer binding transcription factor 4 （Oct4） were calculated. ResultsCompared with the blank group， the model group showed reduced body weight， ovarian wet weight， and ovarian index （P<0.01） and a disordered estrus cycle （P<0.01）. In addition， the levels of serum follicle-stimulating hormone （FSH）， TNF-α， IL-6， and IL-1β were increased （P<0.01）， while anti-Müllerian hormone （AMH） and estradiol （E₂） levels were decreased （P<0.01）. The protein expression of cGAS， p-STING/STING， and p-TBK1/TBK1 in ovarian tissue was increased （P<0.05， P<0.01）， while that of OSCs stemness factors MVH and Fragilis was reduced （P<0.01）. Immunofluorescence indicated a reduction in MVH and Oct4 expression in OSCs （P<0.01）. The mRNA expression of inflammatory factors TNF-α， IL-6， and IL-1β in ovarian tissue was increased （P<0.05， P<0.01）. Compared with the model group， the treatment groups exhibited improved body weight， ovarian wet weight， and ovarian index （P<0.05） and a reduced rate of estrus cycle disorder （P<0.05， P<0.01）. The levels of serum FSH， TNF-α， IL-6， and IL-1β were decreased （P<0.05， P<0.01）， while AMH and E₂ levels were increased （P<0.01）. The protein expression levels of cGAS， p-STING/STING， and p-TBK1/TBK1 in ovarian tissue were decreased （P<0.05）， while the protein expression of MVH and Fragilis was increased （P<0.05）， and the fluorescence intensities of MVH and Oct4 were increased （P<0.05， P<0.01）. The mRNA expression of inflammatory factors in ovarian tissue was decreased （P<0.05）. ConclusionZGW alleviate ovarian inflammatory response， regulate ovarian microenvironment homeostasis， and maintain stemness of OSCs in ovarian aging mice probably by modulating the cGAS-STING signaling pathway， thereby improving ovarian function and delaying ovarian aging.

Objective: To investigate the regulatory relationship between long non-coding RNA LINC01578 and c-Myc, and to explore the effect of LINC01578 on the metabolic process of oral squamous cell carcinoma(OSCC). Methods: After c-Myc was knocked down in OSCC cell line CAL27, LINC01578, a long non-coding RNA that is positively regulated by c-Myc, was identified by high-throughput sequencing technology. qRT-PCR was employed to measure the expression levels of c-Myc and LINC01578 in OSCC tissues and adjacent normal tissues. Following overexpression or knockdown of c-Myc in CAL27 and HN6 cells, qRT-PCR was conducted to validate the consistency with sequencing results. The binding of c-Myc to the LINC01578 promoter was confirmed using a dual luciferase reporter assay. Seahorse, ATP production and lactate production assays were utilized to examine the impact of c-Myc on glucose metabolism in OSCC via LINC01578. Colony formation assays assessed the proliferative capacity of OSCC cell lines. Results: qRT-PCR analysis revealed significantly higher expression levels of c-Myc LINC01578 in OSCC tissues compared to adjacent tissues( P < 0. 05 ) , confirming that c⁃Myc positively regulates LINC01578 expression. Consistent with sequencing data , c⁃Myc overexpression markedly upregulated LINC01578 (P < 0. 001) , while c⁃Myc knockdown led to a significant decrease in LINC01578 levels(P < 0. 000 1) . Dual lu ciferase reporter gene assays demonstrated that c⁃Myc directly targets and transcriptionally enhanced LINC01578 ex⁃ pression(P < 0. 001) . Seahorse experiments indicated that c⁃Myc promoted glucose metabolism in OSCC through LINC01578 regulation(P < 0. 05) . Colony formation assays showed that LINC01578 overexpression enhanced OS⁃ CC cell proliferation , whereas LINC01578 knockdown inhibited it. Conclusion c⁃Myc upregulates LINC01578 expression in OSCC cells , thereby modulating glycolysis and promoting cell proliferation.

Objective To understand the genotyping of human immunodeficiency virus (HIV) co-infected hepatitis C virus (HCV) patients in Yunnan Province, and to analyze the differences in viral load, biochemical indicators, and blood routine indicators among different genotypes, in order to provide a laboratory basis for the diagnosis and clinical treatment of HIV/HCV co-infected patients. Methods From November 2022 to June 2023, the serum samples and basic information of patients diagnosed with HIV/HCV co-infection were collected in the antiviral outpatient clinic of Yunnan Provincial Hospital of Infectious Diseases. The HCV viral load was detected by one-step qRT-PCR amplification, the positive samples were sequenced, and genotyping was determined based on NS5 gene sequence. The differences in biochemical and blood routine indexes between HIV patients co-infected with different HCV genotypes and low/high viral loads were analyzed. Results A total of 126 HIV/HCV co-infected patients were collected, including 20 HCV genotype 1 (15.9%), 91 HCV genotype 3 (72.2%), and 15 HCV genotype 6 (11.9%). The maximum and minimum viral load of the three HCV genotypes were as follows: HCV type 1 (1.0×108, 4.8×104 IU/mL), HCV type 3 (2.2×108, 2.9×102 IU/mL), and HCV type 6 (8.1×107, 6.8×104 IU/mL). The results showed that there was no significant difference between HIV co-infection with different genotypes of HCV and three HIV treatment schemes, including nucleoside reverse transcriptase inhibitors+integrase strand transfer inhibitors (NRTIs+INSTIs), nucleoside reverse transcriptase inhibitors+non-nucleoside reverse transcriptase inhibitors (NRTIs+NNRTIs) and nucleoside reverse transcriptase inhibitors+protease inhibitor (NRTIs+PLs), and the viral load of patients (P>0.05). The analysis of biochemical indexes such as total bilirubin (TBIL), direct bilirubin (DBIL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA), and blood routine indexes such as white blood cell (WBC), red blood cell (RBC), hemoglobin (HGB), platelet (PLT), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) among different HCV genotypes and low/high viral loads showed that there was no significant difference in biochemical indexes and blood routine indexes between low/high viral loads of HIV co-infected HCV patients (P>0.05); however, the biochemical indicators TBIL, IBIL and MCHC were significantly different statistically between patients with genotype 3 HCV infection and those with genotype 1 HCV infection (P<0.05), while other biochemical and blood routine indexes were not statistically different among different HCV genotypes (P>0.05). Conclusions There are six subtypes of HCV co-infection in HIV patients in Kunming, Yunnan Province, including three genes of genotype 1, 3, and 6. Among them, genotype 3 HCV is the main prevalent genetic virus among HIV co-infected populations. The TBIL, IBIL and MCHC values of HIV patients co-infected with HCV type 3 are different from those infected with HCV type 1.

Objective To evaluate the molluscicidal effect of spraying different formulations of niclosamide ethanolamine salt with drones against Oncomelania hupensis in ditches. Methods A semi-dry and semi-wet ditch with O. hupensis snails was selected in the second branch field of Jiangbei Farm, Jiangling County, Hubei Province in May 2023, and divided into 4 experimental areas, named groups A1, A2, B1 and B2. Environmental cleaning was performed in groups A1 and B2, and was not conducted in groups A2 or B2. Then, 50% wettable powder of niclosamide ethanolamine salt was sprayed with drones at an effective dose of 2 g/m² in groups A1 and A2, and 5% niclosamide ethanolamine salt granule was sprayed with drones at an effective dose of 2 g/m² in groups B1 and B2. O. hupensis snails were surveyed using the systematic sampling method 1, 3, 5, 7, 14 days after spraying, and the natural mortality and corrected mortality of O. hupensis snails were calculated. Results The occurrence of frames with living snails, mean density of living snails and natural mortality of snails were 97.50% (117/120), 6.30 snails/0.1 m² and 1.18% (9/765) in the test ditch before spraying, respectively. There were significant differences in the mortality of snails among four groups 1, 3, 5, 7 and 14 days after spraying niclosamide formulations with drones (χ² = 17.230, 51.707, 65.184, 204.050 and 34.435, all P values < 0.01). The overall mortality rates of snails were 94.51% (1 051/1 112), 79.44% (908/1 143), 96.54% (977/1 012) and 88.55% (1 021/1 153) in groups A1, A2, B1 and B2 (χ² = 207.773, P < 0.05), respectively. In addition, there was no significant difference in the overall snail mortality between groups A1 and B1 (P > 0.05), and the snail mortality in groups A1 and B1 were both statistically different from that in groups A2 and B2 (all P values < 0.05). Conclusion Both 50% wettlable powder of niclosamide ethanolamine salt and 5% niclosamide ethanolamine salt granule sprayed with drones are active against O. hupensis snails in ditches, and environmental cleaning may improve the molluscicidal effect.

Pancreatic cancer induced by mutation KRAS exhibited a higher risk of incidence, recurrence and mortality. C-Myc is downstream of KRAS and can be involved in the regulation of multiple oncogenic pathways and signaling pathways in pancreatic cancer. Over expressing of C-Myc promotes glycolysis and glutamine uptake in pancreatic cancer cells, promotes cell metabolism and proliferation, is an important factor driving the progress and maintenance of pancreatic cancer, and is related to chemotherapy and immunotherapy drug resistance. C-Myc also interacts with cell cyclin-dependent kinase(CDK) and non-coding RNA to regulate the proliferation, development and metastasis of pancreatic cancer. Therefore, targeting C-Myc was regarded as an effective strategy for the treatment of pancreatic cancer. The activation of C-Myc depends on heterodimerization with its partner MAX and thereby paly a role through binding to the canonical E-Box sequence 5’-CACGTG-3’. Researches showed direct targeting of C-Myc can inhibit the growth of pancreatic carcinoma,such as promoting the degradation of C-Myc, inhibiting the binding of C-Myc/MAX and blocking the binding of C-Myc/MAX to E-box. However, direct targeting has been proved challenging because of its special protein structure. Indirect targeting of C-Myc provided a new strategy for the treatment of pancreatic cancer. C-Myc can be indirected targeting through inhibiting transcription and translation of C-Myc, C-Myc-MAX heterodimerization and promote the ubiquitination and degradation of C-Myc, thus affects the occurrence, development and metastasis of pancreatic cancer.

Objective:To determine the clinical application value of transcranial sonography (TCS) in the diagnosis of attention deficit hyperactivity disorder (ADHD) in children.Methods:A total of 50 children aged 6-12 years diagnosed with ADHD (ADHD group) and 45 age-matched healthy children (control group) who presented to Suzhou Municipal Hospital and Children′s Hospital of Soochow University from August 2021 to August 2022 were prospectively enrolled for TCS examination. ADHD was diagnosed in accordance with the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-Ⅴ) criteria established by the American Psychiatric Association.Based on clinical symptom characteristics, ADHD was further classified into 3 subtypes, including 14 cases of predominantly inattentive, 3 cases of predominantly hyperactive/impulsive, and 33 cases of combined presentation. The substantia nigra(SN) hyperechoic area and the ratio of SN hyperechoic area to midbrain area (S/M) were measured and compared between the two groups. The examination of the correlation was performed between SN hyperechoic area, S/M ratio, and DSM-Ⅴ scores within the ADHD group.Results:Semi-quantitative analysis: the proportion of the SN grade Ⅲ or more in ADHD group was significantly higher than that in control group [96.00%(48/50) vs 13.3%(6/45), P<0.05]. Quantitative analysis: the area of SN hyperechogenicity and the ratio of S/M were significantly larger in ADHD group than in control group [0.32(0.22, 0.38)cm 2 vs 0.00(0.00, 0.00)cm 2, 7.08(5.11, 8.75)% vs 0.00(0.00, 0.00)%, all P<0.05]. Correlation analysis: The SN hyperechoic area and S/M ratio showed no significant correlations with DSM-Ⅴ scores in the ADHD group ( r=0.144, 0.142, all P>0.05). Conclusions:TCS can detect the SN echo enhancement of ADHD children, and the proportion of SN echo enhancement, SN hyperechoic area and S/M ratio are significantly higher than those of normal children, but the SN hyperecho area and S/M ratio are not significantly correlated with DSM-Ⅴ scores.

Objective To explore the potential categories and influencing factors of the fear of progression in patients with inflammatory bowel diseases(IBD).Methods IBD patients who received inpatient treatment in a tertiary hospital in Nanjing from July 2022 to July 2023 were selected as the study subjects by convenience sampling method.The General Demographic Information Questionnaire,the Chinese version of the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),the Chinese version of Inflammatory Bowel Disease Self-efficacy Scale(IBD-SES),and Social Support Rating Scale(SSRS)were administered to the participants.We applied one-way ANOVA and Logistic regression analysis to identify the factors associated with the potential categories of the fear of progression.Results A total of 303 retumed questionnaires(out of the 310)were valid,resulting an effective response rate of 97.74％.According to the results of latent profile analysis,we classified the respondents into 3 categories by the fear of progression,namely"low risk fear of disease adaptation group"(n=127,41.91％),"medium risk fear of illness distress group"(n=139,45.88％),"high risk fear of dysfunction group"(n=37,12.21％).3 groups showed statistically significant differences in permanent address,self-rated financial pressure,current disease status and self-efficacy(P＜0.05).Conclusion Patients with IBD had obvious differences in characteristics on the fear of progression.Nursing personnel should formulate personalized intervention strategies based on the classification characteristics of the fear of progression of IBD patients.Moreover,nurses should focus on improving patients'self-efficacy and promoting patients to treat medical care,stress and emotion management correctly.
