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 understand the status of occupational health of female migrant workers in different kinds of pharmaceutical industries in Gansu province and to provide the basis for improving occupational health condition.

METHODSOne thousand eight hundreds and one female workers from 16 enterprises were selected by cluster sampling in Gansu province and investigated by interviewing and questionnaires.

RESULTSThere were statistical significances of education level, status of residency registrations, employment relationship and occupational hazards among female workers in three types of enterprises (P < 0.05 or P < 0.01). The morbidities of skin disease in female workers for three kinds of enterprises were 4.46%, 2.53% and 3.70%, respectively. The morbidities of reproductive system disease in female workers for three kinds of enterprises were 48.57%, 36.70% and 36.11%, respectively.

CONCLUSIONThe levels of education and working conditions of female workers in the traditional Chinese medicine, western medicine plants are low. There are more severe occupational hazards in female workers of the traditional Chinese medicine plants.

OBJECTIVETo propose arectal toxicity prediction method based on deformable surface dose accumulation.

METHODSThe clinical data were collected retrospectively from 42patients receiving radiotherapy for cervical cancer. With the first fraction as the reference, the other fractions of rectum surface were registered to the reference fraction to obtain the deformation vector fields (DVFs), which were used to deform and sum the fractional rectal doses to yield the cumulative rectal dose. The cumulative rectal dose was flattened via 3D-2D mapping to generate a 2D rectum surface dose map. Two dosimetric features, namely DVPs and DGPs were extracted. Logistic regression embedded with sequential forward feature selection was used as the prediction model. The predictive performance was evaluated in terms of the accuracy, sensitivity, specificity, and the area under the receiver operating characteristic (ROC) curve (AUC).

RESULTSSignificant improvements for rectum surface DIR were achieved. The best predictive results were achieved by using both DVPs and DGPs as the features with a sensitivity of 79.5%, a specificity of 81.3% and an AUC of 0.88.

CONCLUSIONThe proposed method is feasible for predicting clinical rectal toxicity in patients undergoing radiotherapy for cervical cancer.

OBJECTIVETo evaluate the radiosensitivity and toxicity of sodium glycididazole and cisplatin in concurrent chemoradiotherapy for local advanced nasopharyngeal carcinoma (NPC).

METHODSSixty patients with local advanced NPC (T3-4N2-3M0) were randomly divided into chemoradiotherapy group (n=30) and chemoradiotherapy plus sodium glycididazole group (n=30). All the patients received radiotherapy with (60)Co or 6-8 MV linear accelerator and concurrent injection of cisplatin at a weekly dose of 20 mg/m square. In sodium glycididazole group, the patients received injections of sodium glycididazole at 800 mg/m square prior to the radiotherapy 3 times a week.

RESULTSAt the end of the therapy and 3 month after the radiotherapy, a response rate of 100% was achieved in both of the groups. But at the end of the therapy, the chemoradiotherapy plus sodium glycididazole group showed a significantly higher rate of complete tumor remission than the chemoradiotherapy group (93.3% vs 73.33%, chi(2)=4.32, P=0.038). The patients in the two groups showed similar tolerance of the therapy during the observation.

CONCLUSIONSodium glycididazole plus cisplatin can accelerate the tumor remission and improve the complete remission rate in patients with local advanced NPC without causing severe toxicity.

OBJECTIVETo evaluate the impact of radiofrequency catheter ablation on left atrial (LA) size and function in patients with paroxysmal atrial fibrillation (PAF) and whether there is any difference between segmental pulmonary vein ostial isolation (SPVI) and circumferential pulmonary vein ablation (CPVA).

METHODSSixty-six patients with highly symptomatic atrial fibrillation were assigned to undergo either SPVI or CPVA. Transthorax echocardiography was performed before, 1 day, 1 months and 3 months after the procedure. LA dimension, LA area, late diastolic peak velocity of mitral valve inflow (A) and peak atrial systolic mitral annulus velocity (A') were recorded.

RESULTSOf 66 consecutive patients with symptomatic PAF, 30 patients underwent SPVI and 36 underwent CPVA. After a mean follow-up of (315 +/- 153) days, 21 patients (70%) after SPVI and 28 patients (75%) after CPVA were free of atrial tachyarrhythmia. As compared with the baseline, LA area decreased at 1-month after ablation in SPVI group and at 3-month in CPVA group. LA dimension decreased also in SPVI group, but did not in CPVA group. A velocity and A' velocity declined remarkably 1 day after CPVA, and restored 3 months later. The former went back to the level of baseline, and the latter exceeded it apparently. In SPVI group, A velocity increased at 1-month, and maintained in 3-month after ablation. A' velocity increased at 3-month after ablation. No reduction of A velocity or A' velocity was found after SPVI.

CONCLUSIONSThis study demonstrated a decrease in LA area and an improvement in LA systolic function 3 months after ablation for PAF. The LA damage by CPVA was more than that by SPVI, which was characterized by the reduction of LA function 1 day after procedure and the delayed improvement of LA size and functional parameters.

Objective Critical hand foot and mouth disease(HFMD)progresses from severe type to critical type very fast with high mortality rate.The article was to explore the significance of pediatric early warning score and common inflammatory markers in early diagnosis of critical HFMD cases. Methods A retrospective analysis was conducted on 236 HFMD cases in Hainan Provincial People's Hospital from January 2014 to December 2016. According to HFMD diagnosis and treatment guidelines(2010 Edition)formulated by the Ministry of Health,the selected cases were divided into the general group(n=88),the severe group(n=128)and the critical group(n=20). The white blood cells(WBC),neutrophils(PMN), serum C reactive protein(CRP),procalcitonin(PCT)and other la-boratory parameters were collected at admission,along with Pediatric Early Warning score(PEWS)and Pediatric Critical Illness Score(PCIS). The data of each group were compared by ROC curve analysis. Results The median number of WBC and PMN in the criti-cal group was 15.36×109/L and 10.09×109/L,respectively,which were significantly higher than those of severe group(P<0.05). However,no significant difference was found between general group and severe group(P>0.05). The serum levels of CRP and PCT in general group were higher than those in severe group and critical group,and the difference was statistically significant(P<0.05). The PEWS[(6.1±2.42)vs(0.99±0.77)]and PCIS[(78.7±13.6)vs(99.03±2.12)]in critical group were significantly higher than those in severe group,which were of statistically significance(P<0.05). According to the ROC analysis,the area under the ROC curve of PEWS early warning score for children was(0.962~1.000),(P<0.05)and the best diagnosis limit PEWS was 3.5. The PEWS and PCIS correlation analysis showed the Pearson correlation coefficient was -0.885(P<0.05). Conclusion Common clini-cal inflammatory markers can not be taken as quantitative indicators for the early diagnosis of critical HFMD. The PEWS is an ideal quantitative index for early diagnosis of critical HFMD.
