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 gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Aim To investigate the mechanism by which sufentanil(Suf)improved hypoxia-reoxygen-ation(H/R)-induced myocardial cell injury by regula-ting hypoxia inducible factor-1α(HIF-1α)and KC-NQ1 opposite strand/antisense transcript 1(Kcnq1ot1).Methods Bioinformatics analysis was conducted to predict the interaction between HIF-1αand Kcnq1ot1.Subsequently,H9c2 cells were divided into multiple treatment groups:Ctrl group,H/R group,and Suf group.Further grouping was based on different transfection conditions,including oe-HIF-1α group,oe-HIF-1α+Suf group,sh-HIF-1α group,and sh-HIF-1α+Kcnq1ot1 group.Cell viability was detected u-sing the MTT assay,cell apoptosis was detected using the TUNEL assay,and the concentrations of CK-MB and HBDH in cell supernatants were measured using ELISA.HIF-1α protein expression in cellswas deter-mined by Western blot,and the mRNA expression level of Kcnq1ot1 was measured by reverse transcription quantitative PCR(RT-qPCR).Additionally,a rat model of myocardial is chemia reperfusion was con-structed to evaluate the therapeutic potential of Suf for myocardial ischemia reperfusion injury in vivo.Results The results of bioinformatics analysis showed a direct interaction between HIF-1α and Kcnq1ot1.Compared with the Ctrl group,the H/R group showed significantly reduced H9c2 cell viability,increased cell apoptosis,and significantly upregulated concentrations of CK-MB and HBDH,along with significantly enhanced expres-sion of HIF-1α and Kcnq1ot1(all P<0.05).When H9c2 cells were transfected with oe-HIF-1 α,cell via-bility further decreased,apoptosis was worsened,and CK-MB and HBDH concentrations further increased(all P<0.05);however,these adverse effects were significantly inhibited when combined with Suf inter-vention(all P<0.05).Additionally,compared with the H/R group,the sh-HIF-1α group showed signifi-cantly improved cell viability,reduced apoptosis and decreased CK-MB and HBDH concentrations(all P<0.05);however,these improvements were partially re-versed upon transfection with Kcnq1ot1(all P<0.05).Animal experiments confirmed that Suf could improve myocardial ischemia-reperfusion injury in myo-cardial ischemia-reperfusion injury rats.Conclusions Suf improves myocardial H/R injury by inhibiting the HIF-1α-Kcnq1ot1.

BACKGROUND:Acupuncture is an effective method for lumbar pain in lumbar disc herniation,but its mechanism has not yet been clarified.Factors related to the JAK2/STAT3 signaling pathway regulate the body's inflammatory response and are involved in the process of neuropathic pain. OBJECTIVE:To study the mechanism of acupuncture on lumbar disc herniation in a rat model based on the JAK2/STAT3 signaling pathway. METHODS:Forty Sprague-Dawley rats were randomly divided into four groups:sham operation group,model group,acupuncture group,and acupuncture+agonist group,with 10 rats in each group.Animal models of L5 lumbar disc herniation was constructed through autologous disc cell transplantation in the model group,acupuncture group,and acupuncture+agonist group.Rats in the acupuncture group and the acupuncture+agonist group received acupuncture treatment(Yanglingquan,Shenshu,Huantiao,and Dachangshu acupoints)at 3 days after modeling,and acupuncture treatment was given once a day,20 minutes each,for 15 consecutive days.Rats in the acupuncture+agonist group were injected intrathecally with coumermycin A1,a JAK2 agonist,into the L4/L5 intervertebral space,once a day,20 minutes each,prior to the acupuncture at 6,12,and 18 days after modeling.Paw withdrawal mechanical threshold was detected before and 3,6,9,12,15,and 18 days after modeling.At 18 days after modeling,serum inflammatory factor levels were detected,hematoxylin-eosin staining was performed to observe the morphology of L5-L6 tissues,RT-PCR was performed to detect the expression of JAK2 and STAT3 mRNAs in L5-L6 tissues,and western blot was performed to detect the expression of JAK2,p-JAK2 and p-STAT3 proteins in L5-L6 tissues. RESULTS AND CONCLUSION:The paw withdrawal mechanical thresholds of rats in the model group at different time points after modeling were lower than those in the sham operation group(P<0.05),the paw withdrawal mechanical thresholds of rats in the acupuncture group were higher than those in the model group at 9,12,15,and 18 days after modeling(P<0.05),and the paw withdrawal mechanical thresholds of rats in the acupuncture+agonist group were lower than those in the acupuncture group at 9,12,15,and 18 days after modeling(P<0.05).The levels of interleukin 6,tumor necrosis factor α,neurotransmitter substance P,and brain neuropeptide Y were elevated in the model group compared with the sham operation group(P<0.05);the levels of all four inflammatory factors were reduced in the acupuncture group compared with the model group(P<0.05);and the levels of all four inflammatory factors were elevated in the acupuncture+agonist group compared with the acupuncture group(P<0.05).Hematoxylin-eosin staining showed that lumbar degeneration was obvious in the model group but reduced in the acupuncture group and the acupuncture+agonist group.Moreover,the reduction was more obvious in the acupuncture group compared with the acupuncture+agonist group.The JAK2 and STAT3 mRNA expression as well as the p-JAK2 and p-STAT3 protein expression were elevated in the model group compared with the sham operation group(P<0.05),were decreased in the acupuncture group compared with the model group(P<0.05),and were increased in the acupuncture+agonist group compared with the acupuncture group(P<0.05).To conclude,acupuncture can alleviate inflammation to exert analgesic effects in the rat model of lumbar disc herniation,and its mechanism of action may be related to the inhibition of the JAK2/STAT3 signaling pathway.
