Objective To investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.

Objective To evaluate the efficacy of complete pelvic floor peritoneal reconstruction in reducing postoperative ileus incidence and accelerating recovery following laparoscopic radical cystectomy with orthotopic neobladder construction.Methods A retrospective study was conducted to select 62 patients who underwent the operation in Qujing Hospital Affiliated to Kunming Medical University from January 2017 to September 2024.According to whether complete pelvic floor peritoneal reconstruction was performed during the operation,they were divided into the conventional group(n=25)and the reconstruction group(n=37).Postoperative ileus rates and recovery parameters were compared to assess the clinical value of complete pelvic floor peritoneal reconstruction.Results The reconstruction group showed better postoperative recovery compared to the routine group:gastrointestinal function recovery time[3(2,4)d vs 4(3,5)d,P=0.032],abdominal drainage time[12(10,13.5)d vs 14(12,15)d,P=0.006],pelvic drainage time[12(9,13.5)d vs 14(11,16)d,P=0.015],postoperative hospital stay[18(15.5,26)d vs 25(17,30.5)d,P=0.016],and hospital expenses[(53,695.67±10,182.43)yuan vs(60,803.73±14,449.24)yuan,P=0.027].Postoperative nutritional markers,including total protein[(64.49±6.82)g/L vs.(61.56±4.03)g/L,P=0.038]and albumin[(36.08±5.29)g/L vs.(33.40±3.57)g/L,P=0.020],were higher in the reconstruction group.No significant difference was found in ileus incidence(44.00%vs.32.43%,P=0.355).Other parameters—baseline characteristics,postoperative globulin and prealbumin levels,gastric tube retention,stent/catheter removal time,and complications(anastomotic leakage,urinary fistula,wound infection)—showed no intergroup differences(P>0.05).Conclusion The application of complete pelvic floor peritoneal reconstruction technique in laparoscopic radical cystectomy with orthotonic neobladder provides better protection for the intestine,reduces surgical area adhesions,promotes gastrointestinal function recovery,shortens abdominal and pelvic drainage times,accelerates patient rehabilitation,reduces hospital stay and expenses.However,whether it can effectively reduce postoperative intestinal obstruction rates still requires more data and experimental verification.

BACKGROUND: The clinical impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) in patients treated with PCI for chronic total occlusion (CTO) was still undetermined. METHODS: All CTO vessels treated with successful anatomical PCI in patients from PANDA III trial were retrospectively measured for post-PCI QFR. The primary outcome was 2-year vessel-oriented composite endpoints (VOCEs, composite of target vessel-related cardiac death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization). Receiver operator characteristic curve analysis was conducted to identify optimal cutoff value of post-PCI QFR for predicting the 2-year VOCEs, and all vessels were stratified by this optimal cutoff value. Cox proportional hazards models were employed to calculate the hazard ratio (HR) with 95% CI. RESULTS: Among 428 CTO vessels treated with PCI, 353 vessels (82.5%) were analyzable for post-PCI QFR. 31 VOCEs (8.7%) occurred at 2 years. Mean value of post-PCI QFR was 0.92 ± 0.13. Receiver operator characteristic curve analysis shown the optimal cutoff value of post-PCI QFR for predicting 2-year VOCEs was 0.91. The incidence of 2-year VOCEs in the vessel with post-PCI QFR < 0.91 (n = 91) was significantly higher compared with the vessels with post-PCI QFR ≥ 0.91 (n = 262) (22.0% vs. 4.2%, HR = 4.98, 95% CI: 2.32-10.70). CONCLUSIONS Higher post-PCI QFR values were associated with improved prognosis in the PCI practice for coronary CTO. Achieving functionally optimal PCI results (post-PCI QFR value ≥ 0.91) tends to get better prognosis for patients with CTO lesions.

Objective To investigate the prevalence of specific IgE antibodies against Alternaria alternata and Aspergillus fumigatus in serum samples from clinical allergy patients across selected provinces in China.Methods Data on specific IgE antibodies for Alternaria A.and Aspergillus F.were collected from 20 hospital laboratories in 17 cities spanning 11 provinces.The study analyzed the levels of specific IgE and their variations across different provinces and seasons.Results A total of 27 471 cases of Alternaria A.and 32 843 cases of Aspergillus F.specific IgE data were included.The national average positive rate of Alternaria A.IgE was 10.40%,with the highest rate of 22.68%in Jiangsu and the lowest rate of 2.06%in Guangxi.For Aspergillus F.specific IgE,the average positive rate was 4.24%,with Hubei province having the highest rate(7.25%)and Hunan province the lowest(1.23%).The difference in IgE levels for both Alternaria A.and Aspergillus F.among provinces were statistically significant(H=9 955,16 993,all P<0.0001).Among patients,5.85%had Alternaria A.specific IgE levels at grade 3 or above,while only 0.57%had Aspergillus F.specific IgE levels at this level.When examining seasonal variations using data from Liaoning,Hunan and Anhui provinces,significant seasonal changes were observed for both Alternaria A.and Aspergillus F.IgE antibodies(HAlternaria A=347.6,338.0,401.3,HAspergillus F=196.6,133.7,231.7,all P<0.0001).Conclusion The sensitization to Alternaria A.and Aspergillus F.exhibits distinct geographical characteristics and vary significantly with seasons.Given the relatively high IgE levels associated with Alternaria A.,it should be given adequate clinical attention.

This study analyzed the variations and evolution characteristics of influenza B Victoria(BV)virus in the Yellow River Delta region of China during 2021-2024.Throat swabs were collected from people with influenza-like illness(ILI)from 2021 to 2024 in Binzhou and Dongying,China.Viral isolation was performed,and 22 representative influenza BV isolates were selected for whole genome sequencing.Phylogenetic analysis of whole-genome sequences was performed in MegAlign and MEGA software.A total of 27 674 samples were obtained,and the overall positivity rate of influenza virus(A/H3N2,A/H1N1,BV)was 11.1％.Our surveillance data indicated that influenza B virus was detected in 2 years,which showed positivity rates of 28.2％and 1.7％,respectively.Statistically significant differences in the positivity rates of influenza BV viruses were observed(x2=3 641.791,P＜0.001).The median pairwise sequence identities ranged from 98.7％to 99.3％for eight segments of 22 viral sequences.The isolates for the monitoring years 2021-2024 were located in clades V1A.3a.1 and V1A.3a.2.Intra-lineage reassortments were discovered in B/shandongbincheng17/2022.The NA gene of one isolate exhibited an increase in the 488NLTV N-glycoproteome site.The K338R mutation occurred in the PA gene.Three locus deletion or insertion mutations occurred in the MP gene.The BV influenza epidemic was prevalent every other year;the intensity ranged from strong to weak;and the duration ranged from long to short in the Yellow River Delta region of China during 2021-2022.Influ-enza B virus formed intra-lineage reassortments,and showed significant mutations in NA gene,PA gene,and MP gene.

This study aims to investigate the effects of aerobic exercise on neuroinflammation in AD mice and explore the mechanisms of neuroinflammation regulated by the blood-brain barrier,lipopolysaccharide(LPS)displacement,and glial cell activation.Twenty 3-month-old male APP/PS1 double transgenic mice were used,which were randomly divided into a sedentary group(SE-AD)and an aerobic exercise group(Run-AD),and 10 3-month-old male C57BL/6 mice were used as the control group(WT).The Run-AD group underwent 12 weeks of aerobic training.The results of the water maze showed that aerobic exercise improved the learning and memory capacity of AD mice(P＜0.05).The results of H&E stai-ning and Nissl staining showed that aerobic exercise reduced necrotic cells and inflammatory cell infiltra-tion in the cerebral cortex,as well as nuclear condensation in the CA1 and GD regions of the hippocam-pus(P＜0.05,P＜0.01),and increased the area of Nissl bodies in the cerebral cortex and hippocam-pal CA3 and DG regions.Western blotting and ELISA results showed that aerobic exercise increased the expression of Occludin,ZO-1 and Claudin-5 proteins in the brain(P＜0.01),and decreased the levels of LPS in the brain(P＜0.01).The qRT-PCR results exhibited that aerobic exercise decreased the ex-pression of TLR4,MyD88,NF-κB,IL-1β,and TNF-α mRNA(P＜0.05,P＜0.01).The results of immunofluorescence staining revealed that aerobic exercise reduced the fluorescence area of brain IL-1βand TNF-α proteins(P＜0.05,P＜0.01),as well as the fluorescence area of Iba-1,GFAP,and TLR4 proteins in the cerebral cortex and hippocampus(P＜0.05,P＜0.01).There was a high degree of overlap between Iba-1 and TLR4 fluorescence in the cerebral cortex,and GFAP was localized around Iba-1.In summary,aerobic exercise attenuates neuroinflammation in AD mice by protecting the blood-brain barrier,reducing the displacement of LPS,and subsequently weakening the immune activation of microglia to regulate the TLR4/MyD88/NF-κB signaling pathway to alleviate neuroinflammation.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

Objective Evaluate the effects of different solvent extracts from Jujing Pills on improving retinal damage in kidney Yang deficiency aging mice and explore the underlying mechanism.Methods A composite modeling method of subcutaneous injection of D-galactose and hind limb injection of hydrocortisone was used to establish a kidney Yang deficiency type aging mouse model,and various solvent extract of Jujing Pills were given for intervention treatment.The improvement effect of different solvent extracts of Jujing Pills on aging mice with kidney Yang deficiency was evaluated by observing physical signs,measuring serum oxidative stress marker levels,and cyclic nucleotide levels.Optical coherence tomography(OCT)was used to detect the condition of the mouse retina,HE staining was used to detect the degree of retinal cell damage,TUNEL staining was used to detect retinal cell apoptosis,assay kit was used to detect oxidative stress factor expression,enzyme-linked immunosorbent assay was used to detect the expression of ciliary neurotrophic factor(CNTF),brain-derived neurotrophic factor(BDNF),and nerve growth factor(NGF)in the mouse eyeball,and Western blotting(WB)was used to quantitatively analyze the expression levels of apoptosis and neurotrophic pathway related proteins in the mouse retina tissue.Results Compared with the control group,the model group mice showed slow weight gain,reduced activity,decreased expression of antioxidant factors such as superoxide dismutase(SOD)and glutathione(GSH)in serum(P<0.01),and decreased cAMP/cGMP ratio(P<0.01).Different solvent extracts of Jujing Pills significantly increased the expression of antioxidant factors such as SOD and GSH(P<0.05),reduced the production of oxidative product malondialdehyde(MDA)(P<0.01),and increased the cAMP/cGMP ratio(P<0.01);Significantly increased the retinal thickness of model mice(P<0.01),improved retinal damage and inhibited retinal cell apoptosis(P<0.01),and significantly downregulated the ratio expression levels of Cleaved Caspase-3 and Caspase-3(P<0.01);The expression of CNTF,BDNF,and NGF was upregulated by water extracted medicinal residue alcohol extract,water extracted alcohol sediment,and total extract(P<0.01).The phosphorylation levels of CREB and ERK in the eyeball were significantly upregulated by water extracted medicinal residue alcohol extract and total extract(P<0.05).Conclusion Different solvent extracts of Jujing Pills can exert different pharmacological effects on improving retinal damage in aging mice with kidney yang deficiency model.Its mechanism of action is related to improving retinal apoptosis caused by oxidative stress and increasing the expression of nutritional factors.

This study identified 8 members including NjBIN2 of the GSK3 family in Nardostachys jatamansi by bioinformatics analysis. Moreover, the phylogenetic tree revealed that the GKS3 family members of N. jatamansi had a close relationship with those of Arabidopsis. RT-qPCR results showed that NjBIN2 presented a tissue-specific expression pattern with the highest expression in roots, suggesting that NjBIN2 played a role in root growth and development. In addition, the application of epibrassinolide or the brassinosteroid(BR) synthesis inhibitor(brassinazole) altered the expression pattern of NjBIN2 and influenced the photomorphogenesis(cotyledon opening) and root development of N. jatamansi, which provided direct evidence about the functions of NjBIN2. In conclusion, this study highlights the roles of BIN2 in regulating the growth and development of N. jatamansi by analyzing the expression pattern and biological function of NjBIN2. It not only enriches the understanding about the regulatory mechanism of the growth and development of N. jatamansi but also provides a theoretical basis and potential gene targets for molecular breeding of N. jatamansi with improved quality in the future.
