The epidemiological and spatiotemporal clustering characteristics of dengue fever in Fujian Province were ana-lyzed,to provide a scientific basis for dengue fever prevention and control.Descriptive epidemiology,spatial autocorrelation a-nalysis,and spatiotemporal scanning were used to analyze dengue fever cases in Fujian Province from 2011 to 2023.In this peri-od,a total of 3 586 cases of dengue fever were reported in Fujian Province,including 2 360 local cases,1 134 imported cases from abroad,and 92 imported cases from China.Cases were reported in ten prefectures and cities of the province,and 81 out of 88 counties reported cases.Imported cases were reported throughout the year in Fujian Province,but the occurrence of local ca-ses showed clear seasonality.Local cases and domestic imports were concentrated in August to October,whereas overseas im-ports occurred primarily from June to October.The imported cases were mainly from Southeast Asian countries,but a trend of spreading from Southeast Asian countries to South Asia,Africa,the Americas,and other regions,was observed.Spatio-tem-poral clustering of dengue fever was found in Fujian Province(Moran's I value 0.14-0.66,P＜0.05),and the high-high ag-gregation areas were distributed primarily in Fuzhou,Quanzhou,and Putian.Spatio-temporal scanning detected three aggrega-tion areas:one main and two secondary.The aggregation time was from the end of July to October,and the distribution was primarily in Fuzhou,Quanzhou,Putian,Zhangzhou,and Xiamen.The distribution of dengue fever in Fujian Province showed clear spatial and temporal clustering from the end of July to October,and the distribution was primarily in Fuzhou,Quanzhou,Putian,Zhangzhou,and Xiamen.For high concentration areas,national health campaigns,mosquito prevention and control,epidemic surveillance,medical personnel training,and other relevant measures could be carried out in advance before local cases appear every year.Reduce local transmission of dengue fever due to importation.

OBJECTIVE: This study reports the first imported case of Lassa fever (LF) in China. Laboratory detection and molecular epidemiological analysis of the Lassa virus (LASV) from this case offer valuable insights for the prevention and control of LF. METHODS: Samples of cerebrospinal fluid (CSF), blood, urine, saliva, and environmental materials were collected from the patient and their close contacts for LASV nucleotide detection. Whole-genome sequencing was performed on positive samples to analyze the genetic characteristics of the virus. RESULTS: LASV was detected in the patient's CSF, blood, and urine, while all samples from close contacts and the environment tested negative. The virus belongs to the lineage IV strain and shares the highest homology with strains from Sierra Leone. The variability in the glycoprotein complex (GPC) among different strains ranged from 3.9% to 15.1%, higher than previously reported for the seven known lineages. Amino acid mutation analysis revealed multiple mutations within the GPC immunogenic epitopes, increasing strain diversity and potentially impacting immune response. CONCLUSION The case was confirmed through nucleotide detection, with no evidence of secondary transmission or viral spread. The LASV strain identified belongs to lineage IV, with broader GPC variability than previously reported. Mutations in the immune-related sites of GPC may affect immune responses, necessitating heightened vigilance regarding the virus.

AIM: To investigate the necessity of placing inferior vena cava filter in systemic thrombolytic therapy for patients with acute deep vein thrombosis. METHODS: Retrospectively summarized the clinical data of patients who received urokinase for deep vein thrombosis in the Third Xiangya Hospital of Central South University from September 2006 to April 2020, and discussed the necessity of placing inferior vena cava filter. RESULTS: A total of 549 patients were enrolled, including 294 patients in the filter group (154 males, 140 females) and 255 patients in the non-filter group (126 males, 129 females). Among 268 cases of proximal DVT in the filter group, thirty-five cases were complicated with pulmonary embolism before thrombolysis; and there were 218 cases of proximal DVT in the non-filter group and 16 cases of pulmonary embolism before thrombolysis, with statistical difference between the two groups (P=0.038 and 0.023, respectively). The total amount of urokinase in the filter group was (1 636.3±910.0) thousand units, and that in the non-filter group was (1 490.2±777.2) thousand units, with statistical difference between the two groups (P=0.045). However, there were no statistical differences in the days of use of urokinase and the proportion of patients with adequate anticoagulation. In this study, among 255 patients in non-filter group underwent thrombolysis, only 1 patient developed pulmonary embolism after thrombolysis (P=0.282). CONCLUSION: Inferior vena cava filter is not always necessary for patients with acute deep vein thrombosis during systemic thrombolytic therapy.

OBJECTIVETo evaluate the clinical outcomes between extreme lateral interbody fusion and conventional posterior operation in the treatment of upper lumbar disc herniation.

METHODSAmong 60 patients with upper lumbar disc herniation were treated with extreme lateral interbody fusion(XLIF) or conventional posterior operation from June 2010 to December 2014, 30 patients(19 males and 11 females) were treated with XLIF (XLIF group); and the other 30 patients(17 males and 13 females) were treated with conventional posterior operation (conventional group). In XLIF group, the lesions occurred at T₁₂L₁ segments in 2 patients, at L₁,₂ segments in 6 patients, at L₂,₃ segments in 10 patients, and at L₃,₄ segment in 12 patients. In conventional group, the lesions occurred at T₁₂L₁ segments in 1 patient, at L₁,₂ segments in 6 patients, at L₂,₃ segments in 8 patients, and at L₃,₄ segment in 15 patients. Operative incision lengths, time, blood loss, postoperative draining volume, hospital stays were recorded. Pre-and post-operative visual analogue score(VAS) and Japanese Orthopedic Association(JOA) were compared between two groups. According to the image data, the intervertebral fusion device was observed to be displaced and the rate of interbody fusion was analyzed.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 48 months, with an average of 29 months. The complications included 2 femoral nerve damage in XLIF group (postoperative recovery within 3 months) and superficial incision infection in conventional group(cured by anti-infection). There were no patients with cerebrospinal fluid leakage(CSFL), cauda equina injuries or functional deterioration in the nerve root of lower limbs. In the XLIF group: the operative time was (65.6±20.5) minutes, blood loss was (48.8±15.3) ml, postoperative draining volume was 0 ml. In the conventional group: the operative time was (135.2±33.9) minutes, blood loss was (260.3±125.7) ml, postoperative draining volume was (207.1±50.2) ml. The operative time, blood loss, postoperative draining volume in XLIF group were less than those in the conventional group(<0.05). The JOA and VAS score were significantly improved in both groups during the follow-up period compared with those before operation(<0.05). But the difference of the JOA and VAS score between the two groups 1, 6, and 24 months after surgery had not significant differences(>0.05). There were no significant differences in the fusion rate between the two groups 6 and 12 months after operation(>0.05).

CONCLUSIONSThe XLIF fusion for the treatment of upper lumbar disc herniation has several advantages such as minimal invasive, stable vertebral plate, less complications and postoperative fusion rate, which has a better clinical effect.

Objective To investigate the effects of Ganlu Xiaodu Pills and its residues on PSGL-1 and proinflammatory cytokines in Coxsackie virus A16 (CoxA16) mouse model; To discuss its antiviral mechanism of action. Methods Totally 150 ICR mice at age of 7 days were randomly divided into normal group, model group, all-side group, aromatic residual group, clearing residual group and removing residual group, with 25 mice in each group. Except for normal group, other groups were injected intraperitoneally with 20 μL of 107TCID50 CoxA16 standard stock solution to establish models. Except for normal group and model group, other groups were given relevant medicine for intervention. The expressions of PSGL-1, TNF-α, IL-1β and IL-4 and histopathological observation were detected after 10 days of medication. Results Except for the normal group, the existence of a large number of CoxA16 in other groups of mouse muscle tissues proved successful modeling. HE staining showed that Ganlu Xiaodu Pills and residual could reduce damage to the muscle by CoxA16 virus. Compared with the normal group, the expression of PSGL-1 protein in the model group increased (P<0.01); compared with the model group, all-side group, aromatic residue group, clearing residual group, removing residual group inhibited the expression of PSGL-1 protein, reduced the inflammatory factors of TNF-α, IL-1β, and IL-4 (P<0.01). Conclusion Ganlu Xiaodu Pills and its residues have anti-inflammatory effects, and the all-side group shows the best efficacy.

To better understand the outcomes of small cell lung cancer (SCLC), we examined the clinical features and prognostic factors of SCLC in this study. A total of 148 patients who were diagnosed as having SCLC between January 2009 and December 2013 in Cancer Center of Union Hospital, Wuhan, China, were enrolled and their clinical features and prognostic factors were retrospectively analyzed. Log-rank test and Cox regression model were employed for analysis of prognostic factors. The 1- and 2-year overall survival (OS) rates were 59.7% and 25.7%, respectively, for limited disease (LD) patients whose median survival time (MST) was 16 months. The 1- and 2-year OS rates were 29.5% and 5.3%, respectively, for extensive disease (ED) patients whose MST was 10 months. The univariate analysis and multivariate analysis revealed that age, tumor stage, serum CEA and Ki-67 antigen were significantly correlated to the outcomes of SCLC, and they were significant prognostic factors for SCLC.

OBJECTIVETo investigate the effect of Jiangtang Yishen Recipe (JTYSR) on high insulin induced cell proliferation of human glomerular mesangial cells (HMCs) and the expression of insulin receptor substrate 1 (IRS-1) and phosphatidylinositol-3-kinase (PI-3K).

METHODSHMCs were divided into 4 groups, i.e., the negative control group, the high insulin model group, the JTYSR group, and the LY294002 group. The concentration of insulin, JTYSR, and LY294002 was respectively confirmed by pre-experiment. Different culture solution was respectively added for different groups. RPMI1640 culture solution was added for HMCs in the negative control group, while HMCs in the rest 3 groups were cultured by 100 nmol/L insulin for 24 h. Meanwhile, HMCs from the JTYSR group and the LY294002 group were exposed to 125 mg/L JTYSR and 80 micromol/L LY294002 respectively for further 48 h. The proliferation of HMCs was detected by MTT and flow cytometry. The protein expression of IRS-1 and PI-3K in HMC was detected by immunohistochemical assay and Western blot. Results The proliferation of HMCs induced by high insulin could be significantly lowered, and the protein expression of IRS-1 and PI-3K could be down-regulated in the JTYSR group and the LY294002 group (P <0.01). Compared with the LY294002 group, the protein expression of IRS-1 and PI-3K could be slightly down-regulated in the JTYSR group (P <0.05).

CONCLUSIONJTYSR could lower high insulin induced proliferation of HMCs, and its mechanism might be related to insulin signaling pathway.

OBJECTIVETo assess the prevalence of serum anti-F in patients with hepatitis C virus (HCV) infection and the distribution of anti-F.

METHODSThe recombinant protein (HCV-F/GST) was coated onto micro titer plates as antigen. Sera of 120 patients with hepatitis C virus infection, 15 patients with hepatitis B, 3 patients with hepatitis E and 10 normal sera were tested by indirect ELISA for detecting anti-F.

RESULTS82 samples out of the 120 (68%) HCV infected patients exhibited a positive anti-F reaction, showing significant difference from the controls with no HCV infection (P < 0.01). Data from logistic analysis showed that the positive rate of anti-F was higher in patients over 50 year olds (OR = 6.675, 95% CI: 2.407-19.071). Patients of midrange, severe phase and hepatic cirrhosis had higher rate than the others (OR = 2.749, 95% CI: 1.470-5.141).

CONCLUSIONPrevalence and distribution of anti-F in Yixing hepatitis C patients was reported and which might be related to the progression of HCV infection.
