ObjectiveTo find out whether there is any difference in the monitoring results of mosq-ovitraps placed in different orientations in multi-storey residential areas, so as to provide a scientific basis for routine and emergency monitoring of Aedes albopictus with mosq-ovitraps in residential areas. MethodsFrom July 6th to October 26th 2023, one mosquito ovitrap was set up in each of the 4 orientations of east, south, west and north around the buildings in a multi-storey residential area in Jinhui Town, Fengxian District, Shanghai. Data was collected and recorded 72 hours after placement. The chi-square test was used to compare the mosquito ovitrap indices (MOIs) of two independent samples, and the Kruskal⁃Wallis H test was used to compare the MOIs of multiple independent samples. ResultsAfter 16 weeks of surveillance, 997 mosquito ovitraps were recovered, of which 211 were positive, with the mosquito ovitrap index (MOI) of 21.16% and the Aedes albopictus density index of 1.03 mosquitoes·ovitrap^-1. The MOIs were higher in September (24.22%) and October (23.96%), and the MOIs in the west, south and north within the two months were all above 20.00%. From July to October, the MOIs in the east, west, south and north were 20.70%, 22.20%, 25.50% and 16.20%, respectively, and the difference in MOIs among the 4 orientations was not statistically significant (χ²=6.647, P=0.084). Stratified analysis by month showed that in August, the south side of the multi-storey residential areas had the highest MOI (31.30%), the north side had the lowest MOI (1.30%), and there was a statistically significant difference in MOI in the east, west, south and north (χ²=25.986, P<0.001). In October, the MOI in the west was the highest (33.30%) and the MOI in the east was the lowest (6.30%), the difference in MOIs of the 4 orientations was statistically significant (χ²=12.007, P=0.007). The MOIs in the south side of the building in the outskirts of the residential area from the 1st week in July to the 4th week in October was lower (19.20%) than that in the south side of the inner building (31.70%), and the difference in MOI was statistically significant (χ²=5.118, P=0.024). ConclusionThe study of MOI in different orientations in a multi-storey residential area is a preliminary exploration based on field work, and the results show that there is a difference in MOIs in different orientations during the peak breeding period of mosquitoes. Further indicators such as temperature, humidity and wind speed in different orientations can be collected to explore the influencing factors of MOIs.

Objective To identify the causative variants in 5 Chinese families with tuberous sclerosis complex(TSC)to provide genetic counseling and prenatal diagnosis.Methods Genetic counseling and clinical diagnosis were performed in 8 patients from five unrelated TSC families by teleconsultation.With informed consent obtained from the participants,3 to 5 mL peripheral blood samples were collected from the probands and their family mem-bers for the extraction of genomic DNA.Candidate pathogenic variants were screened by panel sequencing(PS).The candidate pathogenic variants found in TSC1 and TSC2 by PS were validated by PCR-Sanger sequencing and bioinformatics analysis.Results All the pathogenic mutations were identified in the probands and their available family members.Causative variants in TSC1 or TSC2 were detected in all patients,including three reported variants and two novel variants.The two novel variants,TSC2:c.245G＞A and TSC2:c.235delG,which were predicted to cause the nonsense variant p.(Trp82?)and the frameshift variant p.(Val79Lysfs27?)respectively was believed to introduce premature stop codons.The analysis of family co-segregation and bioinformatics were identified as very positive factors for pathogenicity.Conclusions This result provides more evidences for the genetic counseling and prenatal diagnosis in these families and expand the spectrum of TSC2 pathogenic variants.

Objective:To observe the therapeutic effect of intraocular lens (IOL) protected phacoemulsification (PHACO) in patients with hard nucleus cataract.Methods:A randomized controlled clinical study was conducted.A total of consecutive 120 patients (120 eyes) with hard nucleus cataract of Emery grade Ⅳ or Ⅴ were enrolled from January 2019 to May 2022.The patients were randomly divided into PHACO group receiving routine PHACO, IOL protected PHACO group receiving PHACO under IOL protection, and extracapsular cataract extraction (ECCE) group receiving ECCE, with 40 cases (40 eyes) in each group.Finally, 99 patients completed the follow-up, including 30 cases (30 eyes) in PHACO group, 35 cases (35 eyes) in IOL protected PHACO group, and 34 cases (34 eyes) in ECCE group.The total operation time, intraoperative PHACO time and cumulative energy release of each patient were recorded.The corneal endothelial cell density (ECD), coefficient of variation in endothelial cell area (CV), hexagonal endothelial cell ratio (6A), corneal astigmatism and the number of eyes with different grades of uncorrected visual acuity were measured and compared after 3-month follow-up.The intraoperative and postoperative complications were recorded.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Yanbian University Hospital (NO.2023002).Patients were informed of study content and purpose and signed a consent form before treatment.Results:There was no significant difference in ultrasonic energy and time between PHACO group and IOL protected PHACO group ( P=0.691, 0.982).The total operation time was (38.81±2.73) and (36.45±3.45) minutes in PHACO group and IOL protected PHACO group, significantly shorter than (69.60±4.35) minutes in ECCE group (both at P<0.001).There was no significant difference in age, sex, lens nucleus hardness and other baseline data among the three groups before operation (all at P>0.05).Three months after operation, the number of patients with higher uncorrected visual acuity in PHACO group and IOL protected PHACO group was larger than that in ECCE group ( P=0.006, 0.007).The ECD and 6A in IOL protected PHACO group were (2 155.57±177.88)/mm 2 and (41.31±5.18)%, respectively, which were significantly higher than (1 912.64±224.11)/mm 2 and (36.18±3.27)% in PHACO group, and the CV in IOL protected PHACO group was (50.34±5.90)%, which was lower than (55.67±3.30)% in PHACO group, showing statistically significant differences ( P=0.007, 0.003, 0.005).At 1 week and 3 months after the operation, the corneal astigmatism was significantly lower in IOL-protected PHACO group than in ECCE group, but higher than in PHACO group, and the difference were statistically significant (all at P<0.05). Conclusions:Compared with conventional PHACO, IOL-protected PHACO can effectively reduce the damage of corneal endothelium caused by ultrasonic energy, shorten the operation time and reduce postoperative inflammatory reaction compared with ECCE, and does not significantly increase postoperative corneal astigmatism.IOL-protected PHACO is an effective improved surgical method for patients with hard nucleus cataract.

Objective To explore the diagnosis and treatment of fourth branchial cleft deformity.Methods The clinical data of a patient with bilateral fourth branchial cleft deformity in the neck were summarized,and the literature was reviewed.Results The patient was a 17-year-old male who had a painless lump in his neck for 10 years.During specialized examination,a lump approximately 4.0 cm × 3.0 cm in size could be palpated subcutaneously on the right side of the neck,with clear boundaries,a regular shape,a soft texture,and a wave-like sensation without obvious tender-ness.A fistula with a size of approximately 0.5 cm × 0.5 cm could be observed on the left side of the neck,and yellow clear liquid could be seen flowing out of the fistula.The surrounding skin was locally red and swollen,and the surface temperature of the skin was elevated.Computed tomography examination demonstrated a circular cystic low-density shadow approximately 4.4 cm × 3.4 cm in size in the right supraclavicular and anterior cervical regions.A flocculent isodense image could be observed in the middle;moreover,nodular calcification could be observed at the edge,and the surrounding fat spaces were blurred.The enhanced scan showed mild enhancement of the cyst wall but no obvious en-hancement of the contents.On the left side,a circular nodular shadow with a diameter of approximately 1.4 cm could be seen,with enhanced scanning and circular enhancement.The surrounding skin was thickened,and the subcutaneous fat gap was blurred.Multiple small lymph nodes could be observed on both sides of the neck,with the larger nodes having a short diameter of approximately 0.8 cm.The size and morphology of the thyroid gland were not significantly abnormal,and there was no obvious abnormal density shadow inside of the gland.Upon admission,the diagnosis was a fourth gill fissure cyst in the right neck and a fourth gill fissure fistula in the left neck.Under general anesthesia and intravenous anesthesia,right branchial cleft cyst resection and left branchial cleft fistula resection were performed.Postoperative pathological examination demonstrated a left branchial cleft fistula and a right branchial cleft cyst.The wound healed by first intention,and there was no recurrence after 6 months of follow-up.According to the literature,fourth branchial cleft deformity is a congenital developmental abnormality of the branchial apparatus,the incidence of which accounts for only 1％of all branchial cleft deformities;moreover,it often occurs on the left side.The anatomical position is often located in the cervical root and supraclavicular region,thus demonstrating cysts or sinuses adjacent to the thyroid gland.The di-agnosis should be confirmed by anatomical location,imaging examination or laryngoscopy combined with postoperative pathological results and should be differentiated from cervical masses such as thyroglossal duct cysts and lymph node metastasis.The main treatment methods include surgical procedures and endoscopic cauterization of the internal fistula.The prognosis is generally good,and there is a risk of recurrence;however,cancer rarely occurs.Conclusion Deformi-ty of the fourth branchial fissure is very rare;thus,it should be identified early to avoid excessive and ineffective surgi-cal drainage,reduce potential complications during resection and completely remove the lesion to prevent recurrence.

Fibroblasts are stromal cells widely distributed in tissues and organs throughout the body.Fibroblasts are involved in the synthesis and remodelling of the extracellular matrix.Fibroblasts participate in physiopathological processes such as tissue damage repair,inflammatory responses and immune regulation.Large numbers of activated fibroblasts have been found in fibrosis,autoimmune diseases and tumor lesions.Activated fibroblasts participate in tissue fibrosis and influence the tumor microenvi-ronment mainly by secreting collagen and fibronectin.They also secrete a variety of inflammatory and growth factors that play an immunomodulatory role in autoimmunity and tumors.In recent years,it has been found that modulating fibroblast activation can effectively delay the development of these diseases,and that targeting fibroblast activation biomarkers can assess the development and treatment of these diseases.Therefore,the use of fibroblast-targeted drugs and therapeutic tools is expected to achieve new breakthroughs in the clinical management of fibrosis,autoimmune diseases and tumors.

Objective To investigate the clinical application value of MRI Radiomics score(Radscore)combined with clinicopatho-logical features in predicting postoperative progression-free survival(PFS)of patients with endometrial cancer(EC).Methods A total of 127 patients with EC were selected.The radiomic features of the lesions were extracted from T2 WI,diffusion weighted imaging(DWI)and apparent diffusion coefficient(ADC)images.The features were screened by random forest model and Radscore was calcu-lated.Simultaneously,clinical and pathological characteristics of patients were collected and incorporated,and multivariate Cox regression analysis was used to screen the risk factors related to PFS.The MRI Radscore and clinicopathological features were mapped to the nomogram,and the performance of nomogram was evaluated by receiver operating characteristic(ROC)curve and calibration curve.Results Multivariate Cox regression analysis showed that progesterone receptor(PR),human epididymis protein 4(HE4)and MRI Radscore were independent risk factors for predicting PFS in patients with EC(P＜0.05).The area under the curve(AUC)of the predicted PFS at 1,3 and 5 years after surgery were 0.91,0.804 and 0.776,respectively.Calibration curves showed that nomogram had a good fit in predicting PFS in patients with EC 1,3 and 5 years after surgery.Conclusion The nomogram con-structed based on multi-sequence MRI Radscore and clinicopathological features has favorable accuracy and stability in predicting postoperative PFS in individuals diagnosed with EC.

Objective:To understand the clinical characteristics of human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) patients with renal injury after antiviral therapy in Henan Province, and to explore the risk factors of renal injury.Methods:A cross-sectional study was conducted to investigate HIV infection/AIDS patients receiving antiviral therapy in Zhengzhou Sixth People′s Hospital, Anyang Fifth People′s Hospital, Hebi Third People′s Hospital, Luo Yang Zhoushan Hospital and Lankao Central Hospital in Henan Province from April 1 to September 30, 2023. The clinical information including basic data, antiviral therapy regimens and comorbidities, and laboratory test results (blood urea nitrogen, serum creatinine, blood uric acid, urine routine, urine microalbumin, urine α 1-microglobulin (α 1-MG), urine β 2-microglobulin (β 2-MG), urine retinol binding protein (RBP), urine creatinine, HIV viral load, CD4 + T lymphocyte count) were collected. Multivariate binary logistic regression was used to analyze independent risk factors for renal injury. Results:A total of 2 526 HIV infection/AIDS patients were included, with the age of (45.52±14.28) years and 2 156 (85.4%) males. The main route of transmission was sexual transmission (91.6%, 2 314/2 526). The duration of antiviral therapy was 5.00(2.92, 8.00) years. Tenofovir (TDF)+ lamivudine (3TC)+ non-nucleoside reverse transcriptase inhibitors (NNRTI) accounted for 55.3%(1 396/2 526) of the current antiviral therapy regimen. The percentage of HIV viral load <50 copies/mL was 93.0%(2 350/2 526). The CD4 + T lymphocyte count was 476(337, 645)/μL. There were 156 patients (6.2%) complicated with hepatitis B and/or hepatitis C, 205 patients (8.1%) with diabetes, 379 patients (15.0%) with hyperlipidemia, and 189 patients (7.5%) with hyperuricemia. A total of 1 040 patients (41.2%) with renal injury were found through renal function test, including 355 cases (14.1%) with estimated glomerular filtration rate (eGFR) <60 mL/(min·1.73 m 2) or urine protein positive or urine albumin creatine ratio (UACR) ≥30 mg/g, 682 patients (27.0%) with pure tubular injury presented with only positive for urinary α 1-MG, urinary β 2-MG, or urinary RBP. eGFR< 60 mL/(min·1.73 m 2) was found in 71 cases (2.8%), eGFR from 60 to 89 mL/(min·1.73 m 2) was found in 509 cases (20.2%), and eGFR≥90 mL/(min·1.73 m 2) was found in 1 946 cases (77.0%). A total of 138 patients (5.5%) were identified as having combined chronic kidney disease (CKD). Among them, 110 patients (79.7%) were in CKD stages 1 to 2, and 117 patients (84.8%) were in urinary albumin A2 grade. Multivariate analysis of 355 patients with renal injury who had eGFR<60 mL/(min·1.73 m 2) or positive urine protein in urine routine or UACR ≥30 mg/g showed that ages of 50 to 69 years old (odds ratio( OR)=2.189, 95% confidence interval ( CI) 1.333 to 3.596, P=0.002)), ≥70 years old ( OR=5.190, 95% CI 2.912 to 9.248, P<0.001), female ( OR=1.685, 95% CI 1.241 to 2.286, P=0.001), combined opportunistic infection ( OR=2.521, 95% CI 1.567 to 4.056, P<0.001), combined hepatitis B ( OR=1.962, 95% CI 1.110 to 3.467, P=0.020), combined hepatitis C ( OR=1.883, 95% CI 1.043 to 3.400, P=0.036), combined diabetes ( OR=2.703, 95% CI 1.911 to 3.821, P<0.001), using TDF for two to four years ( OR=1.674, 95% CI 1.103 to 2.459, P=0.015), using TDF for greater than or equal to five years ( OR=1.880, 95% CI 1.287 to 2.746, P=0.001), using TDF combined with lopinavir/ritonavir (LPV/r) ( OR=3.610, 95% CI 2.273 to 5.734, P<0.001) and using TDF combined with non-LPV/r ( OR=1.495, 95% CI 1.036 to 2.157, P=0.031) were the risk factors of renal injury. Conclusions:There is a high proportion of renal injury among HIV infection/AIDS patients after antiviral therapy in Henan Province, including CKD and simple renal tubular injury. Older age, female, comorbidities, and long-term use of TDF are risk factors for renal injury.

Objective The purpose of writing the"Expert consensus on the prevention and control of intracranial hypertension in adult critical illness"(here in after referred to as the"Consensus")aimed to standardize the nursing work related to the prevention and control of elevated intracranial pressure in adult critical illness,and prevent the occurrence of complications such as cerebral herniation.Methods Guided by evidence-based practice,domestic and foreign databases were searched for guidelines,expert consensuses,systematic evaluation,evidence summaries,and original research related to increased intracranial pressure.The search period is from database establishment to March 2024.The high-quality evidence and suggestions in the field was evaluated,extracted,and summarized to form a preliminary consensus.27 experts were invited to conduct 2 rounds of expert inquiry and 8 experts were invited to conduct 2 expert discussion meetings,to revise and improve the content of the initial draft,and to ultimately form a final consensus.Results The effective response rates for both rounds of inquiry questionnaires were 100％,with expert authority coefficients of 0.884,judgment coefficients of 0.964,and familiarity levels of 0.804.The Kendall harmony coefficients for 2 rounds of inquiry were 0.107 and 0.083(P＜0.01),respectively.The consensus includes 4 aspects,including identification,monitoring,prevention and control strategies,emergency treatment and care for increased intracranial pressure.Conclusion This"Consensus"has strong scientific validity and can provide reference basis for nurses to carry out prevention and control of intracranial pressure increase.

Objective:To investigate whether Lycopi Herba can serve as a viable alternative to Alismatis Rhizoma in the treatment of heart failure (HF) through network pharmacology and molecular docking techniques.Methods:TCMSP database was used to filter active components of Lycopi Herba and Alismatis Rhizoma. SwissTargetPrediction database was used to predict potential targets. HF-related targets were collected from databases such as GeneCards, OMIM, and DisGeNET. Venny 2.1.0 was used to draw a Venn diagram illustrating the intersection of targets between Lycopi Herba and Alismatis Rhizoma and HF. A protein-protein interaction (PPI) network was established using the String database, and key targets for the treatment of HF with Lycopi Herba and Alismatis Rhizoma were selected using Cytoscape 3.9.1 software to construct a component-intersection target network. The intersection targets were then analyzed for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways using Metascape. Molecular docking techniques were used to evaluate the affinity between active components and key targets.Results:Lycopi Herba primarily targeted pivotal proteins such as HMGCR and CYP27B1, while Alismatis Rhizoma had a broader target spectrum, including PPARA, JAK2, among others. Shared key targets between the two included HMGCR and ESR1, which were primarily involved in cholesterol synthesis and steroid hormone biosynthesis. Enrichment pathway analysis showed similarities in steroid metabolism between the two; Alismatis Rhizoma, however, was more likely to act through protein phosphorylation regulation and modulating the PI3K-Akt signaling pathway for HF treatment. A unique target for Lycopi Herba in treating HF was CHRM4, indicating its potential for blood pressure regulation and myocardial protection.Conclusions:Both Lycopi Herba and Alismatis Rhizoma exhibit certain commonalities in the treatment of HF, but Alismatis Rhizoma has a wider range of targets and signaling pathways, implying more extensive therapeutic potential. However, considering the nephrotoxicity of Alismatis Rhizoma, Lycopi Herba could be considered as an alternative treatment for HF, especially in patients with renal insufficiency or in the early stages of HF.

Objective:To discuss the effects of different doses of ganoderic acid A(GAA)on the biological activities,glycolysis,and the expression of rate-limiting enzymes of non-small cell lung cancer(NSCLC)PC9 cells,and to clarify the mechanism.Methods:The NSCLC PC9 cells were cultured in vitro and divided into blank control group,low dose(25 μmol·L-1)of GAA group,medium dose(50 μmol·L-1)of GAA group,and high dose(100 μmol·L-1)of GAA group.The methylthiazolydiphenyltetrazolium(MTT)assay was used to detect the survival rates of the PC9 cells in various groups;Transwell chamber assay was used to detect the number of migration cells of the PC9 cells in various groups;the glucose uptakes of the PC9 cells in various groups were detected by glucose assay kit;the levels of ATP in the PC9 cells in various groups were detected by ATP assay kit;the levels of lactic acid in the PC9 cells in various groups were detected by lactate assay kit;the expression levels of hexokinase 2(HK2)and pyruvate kinase M2(PKM2)mRNA in the PC9 cells in various groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)method;the expression levels of HK2 and PKM2 proteins in the PC9 cells in various groups were detected by Western blotting method.Results:The MTT assay results showed that,at 24,48,and 72 h of culture,compared with blank control group,the survival rates of the cells in medium and high doses of GAA groups were significantly decreased(P<0.05).At 72 h of culture,compared with low dose of GAA group,the survival rate of the cells in high dose of GAA group was significantly decreased(P<0.05).The Transwell chamber assay results showed that compared with blank control group,the numbers of migration cells in medium and high doses of GAA groups were significantly decreased(P<0.05);compared with low doses of GAA group,the number of migration cells in high dose of GAA group was significantly decreased(P<0.05).Compared with blank control group,the glucose uptakes and levels of lactic acid in the cells in medium and high dose of GAA groups were significantly decreased(P<0.05),and the level of ATP in the cells in high dose of GAA group was significantly decreased(P<0.05).The RT-qPCR results showed that compared with blank control group,the expression levels of HK2 and PKM2 mRNA in the cells in medium and high doses of GAA groups were significantly decreased(P<0.05).The Western blotting results showed that compared with blank control group,the expression levels of HK2 and PKM2 proteins in the cells in medium and high doses of GAA groups were significantly decreased(P<0.05).Conclusion:Medium and high doses of GAA can inhibit the biological activities of proliferation and migration of the PC9 cells,reduce the glycolysis,and its mechanism may be related to the inhibition of the expressions of the key rate-limiting enzymes HK2 and PKM2.
