Abstract: Objective　To explore the spatial epidemiological characteristics of severe cases hand, foot and mouth disease (HFMD) in Guangxi, China, from 2014 to 2018, and to provide a basis for identifying the high-risk regions as well as the prevention and control of severe cases of HFMD in Guangxi. Methods　Spatial-temporal scanning analysis, global and local spatial autocorrelation analysis were used to analyze the spatial clustering of HFMD. The trend surface analysis was used to evaluate the spatial distribution trend of HFMD. Results　From 2014 to 2018, the incidence and severe case fatality rates of HFMD were 3.89/100 000 and 4.23%, respectively. Monte Carlo scanning analysis showed that the first cluster region was Cenxi City, the second cluster was mainly concentrated in northwest of Guangxi, and the aggregation time was mainly concentrated in April to May and August to October. The global spatial autocorrelation analysis showed that the severe HFMD was significant clustering distribution, and the Moran's I coefficients of the sever cases, severe morbidity and severe case fatality rate were 0.088, 0.118, 0.197, respectively (P<0.05). Local spatial autocorrelation analysis showed that hotspots of severe HFMD cases were concentrated in the southern Guangxi, mainly in Lingshan County. Anselin local Moran's I clustering and outlier analysis indicated that 5 high-high (H-H) clustering regions for fatality were Lingshan, Pubei, Zhongshan, Zhaoping and Pinggui County. There were 6 high-high (H-H) clustering regions for severe incidence rate, namely Lingshan, Qinnan, Lingyun, Youjiang, Bama Yao Autonomous and Pinggui County, and 1 high-low (H-L) clustering region, Cenxi County. The trend surface analysis showed that the overall number of severe cases of death decreased from east or west to the middle, and increased from north to middle, and then decreased to south. Conclusions　Severe HFMD cases in Guangxi have obvious spatial-temporal clustering, and the hop spots are mainly concentrated in southern Guangxi. The prevention and control of HFMD in areas with high incidence of severe cases should be strengthened to reduce the burden of HFMD cases.

OBJECTIVETo identify and determine the congener and level of microcystins in the source water of Taihu Lake.

METHODSImproved method of SPE combined with HPLC was employed to detect the concentration and varieties of microcystins in source water and bloom samples collected from Meiliang Bay, Taihu Lake.

RESULTSThe contents of two predominant microcystin components, MC-RR, and MC-LR, were relatively high in samples during warm months and correlated with the phase of algae growth. The maximum concentrations of MC-RR and MC-LR in water sample reached 3.09 +/- 0.53 microg/L and 2.39 +/- 0.41 microg/L during the period of water bloom in September 2004, respectively. Even without waterbloom, the concentration of MC-LR in source water sample was still higher than the guideline value.

CONCLUSIONThe status of microcystin pollution in this region is serious and measures to monitor and control the growth of cyanobacteria are urgently needed.

This study aims to clarify out the anti-inflammatory mechanism of Qingfei Xiaoyan Wan. Chemical constituents of Qingfei Xiaoyan Wan identified by UPLC Q-TOF, were submit to Molinspiration, PharmMapper and KEGG bioinformatics softwares for predicting their absorption parameters, target proteins and related pathways respectively; and the gene chip and real time-PCR were carried out to investigate the expression of inflammatory genes on lung tissue of guinea pigs or human bronchial epithelial cell lines. The predicted results showed that 19 of the 24 absorbable constituents affected at 9 inflammation-related pathways through 11 protein targets; Qingfei Xiaoyan Wan treatment can significantly reduce the infiltration of cytokines through ERK1 gene and 5 inflammatory pathways (Focal adhesion, Fc epsilon RI, Toll-like receptors, NK cell-mediated cytotoxic, and ERK/MAPK). The results of real time-PCR further confirmed that the anti-inflammatory effects of Qingfei Xiaoyan Wan were due to active ingredients such as arctigenin, cholic acid and sinapic acid intervened focal adhesion, Fc epsilon RI signaling and ERK/MAPK pathways. The novel approach of 'drug-target-pathway' will present an effective strategy for the study of traditional Chinese medicines.

OBJECTIVE: To investigate the clinicopathological features and outcomes between node-negative, early-stage cervical squamous cell carcinoma (SCC) and adenocarcinoma (AC) after hysterectomy. METHODS: Patients diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stages I–IIA cervical SCC and AC between 1988 and 2013 were retrospectively reviewed using the Surveillance, Epidemiology, and End Results database. We used propensity score-matching to balance patient baseline characteristics. Univariate and multivariate Cox regression analyses were used for prognostic analyses of cause-specific survival (CSS) and overall survival (OS). RESULTS: A total of 9,858 patients were identified, comprising 6,117 patients (62.1%) and 3,741 (37.9%) patients with cervical SCC and AC, respectively. Compared with cervical SCC, cervical AC cases were more likely to be younger, diagnosed after 2000, white, and have well-differentiated and FIGO stage IB1 disease. For SCC and AC, the 10-year CSS rates were 93.4% and 94.7%, respectively (p=0.011), and the 10-year OS rates were 89.6% and 92.2%, respectively (p<0.001). Multivariate analysis revealed that age, ethnicity, tumor grade, and FIGO stage were independent prognostic factors of CSS and OS, but that histologic subtype was not associated with CSS and OS. In the propensity score-matched patient population, univariate and multivariate analyses also showed that histologic subtype was not associated with survival outcomes. CONCLUSION: Cervical AC has equivalent survival to cervical SCC in node-negative, early-stage disease after hysterectomy and lymphadenectomy.

OBJECTIVETo investigate the value of serum cystatin C (Cys-C), urinary Cys-C, urinary retinol binding protein (RBP) and urinary neutrophil gelatinase-associated lipocalin (NGAL) in the early assessment of multiple myeloma (MM) and their characteristic changes in different pathological types of renal impairment.

METHODSAccording to glomerular filtration rate (eGFR), the patients were divided into two groups, of which marked group A with normal renal function, the other marked group B with abnormal renal function. Sixty healthy subjects were chosen as control. Detection of the serum Cys-C, urinary RBP, urinary Cys-C, urinary NGAL, serum creatinine (Scr), urinary microalbumin (MAU) and urinary α1-microglobulin (α1-MG) were performed. Renal biopsy was carried out for patients who had abnormal serum Cys-C, urinary Cys-C, urinary RBP, urinary NGAL and were willing to accept further test.

RESULTSCompared with healthy controls, the serum Cys-C, urinary RBP, urinary Cys-C, urinary NGAL of group A were significantly higher than that of healthy controls. Six group A patients received renal biopsy, and varying degrees of renal damage were discovered. The serum Cys-C, urinary RBP, urinary Cys-C and urinary NGAL positive rate were 66.7%, 66.7%, 66.7% and 83.3%, respectively. Of twenty-four cases received biopsy after abnormal examination results were shown, six turned out to be amyloidosis, twelve cast nephropathy (CN) and 6 monoclonal immunoglobulin deposition disease (MIDD). Compared with MIDD and amyloidosis, the urinary Cys-C and NGAL of the CN group are significantly higher (P < 0.05). Compared with CN and amyloidosis, urinary RBP of MIDD is significantly higher (P = 0.043). Compared with MIDD and CN, the MAU of amyloidosis is significantly higher (P = 0.006).

CONCLUSIONCompared with the conventional indicators, serum Cys-C, urinary Cys-C, RBP and NGAL are more sensitive in early assessment of MM patients with renal damage. The MAU is higher in amyloid, the urinary Cys-C and urinary NGAL are significantly elevated in CN, the urinary RBP is significantly elevated in MIDD.

BACKGROUNDHepatitis C virus (HCV) infection may induce autoimmune response and autoantibodies can be detected in chronic hepatitis C (CHC) patients. However, the reported positive rate of autoantibodies in CHC patients in China varies considerably. In this study, we investigated the prevalence of antinuclear antibodies (ANA) and anti-liver-kidney-microsome type 1 autoantibodies (anti-LKM-1) in a large cohort of CHC patients, and analyzed the factors related to the presence of the autoantibodies.

METHODSA total of 360 CHC patients were enrolled in this study. Serum ANA and anti-LKM-1 were detected by indirect immunofluorescence and enzyme-linked immunosorbent assay, respectively. Clinical analysis was performed to disclose the related factors to autoantibody production.

RESULTSThe prevalence of ANA and anti-LKM-1 in CHC patients was 12.5% (45/360) and 2.5% (9/360), respectively. Women had a higher prevalence than men (18.9% vs 11.4%, P = 0.046). Patients with positive autoantibodies had lower HCV RNA levels (1.2 x 10(7) copies/L vs 7.2 x 10(7) copies/L, P < 0.05). Positive ANA was associated with higher serum globulin (P < 0.05). Stratified analysis showed that there were no significant differences in age, HCV genotype, disease course, clinical stage, prevalence of cirrhosis and interferon therapy between autoantibody-positive and -negative subgroups.

CONCLUSIONAutoantibodies can be induced in the course of CHC, and some CHC patients can even develop autoimmune hepatitis.
