Objective:To analyze the levels of individual doses to radiation workers receiving medical radiation exposure in hospitals in Jiangxi province, so as to provide reference for radiation protection.Methods:The radiation workers of different types in medical institutions in Jiangxi were investigated from 2014 to 2018, involving diagnostic radiology, radiotherapy, nuclear medicine and interventional radiology. Statistical analyses were made of the individual doses to medical radiation workers in the province.Results:The total number of monitored workers were 23 833 with average annual individual effective dose of 0.316 mSv. NR1 and NR5, the ratios of the number of workers receiving annual individual doses exceeding 1 and 5 mSv to the total monitored workers were 4.32% and 0.10%, respectively. During the five-year period, the average annual individual effective dose showed a upward and then downward trend, with peak appearing in 2017. A total of 17 909 diagnostic radiologists were monitored, accounting for 75.14% of the total number of monitored workers. The average annual individual effective dose received by workers was 0.329 mSv, the highest, in interventional radiology, followed by diagnostic radiology 0.318 mSv, nuclear medicine 0.283 mSv, and radiotherapy 0.269 mSv, respectively. There were statistically significant differences among radiation workers of different types ( χ2=489.39, P<0.001). Conclusions:The average annual individual effective dose to the radiation workers in medical institutions in Jiangxi province meets the relevant national standards, but with an upward trend in nuclear medicine. The higher levels of individual doses to radiation workers are seen in primary and secondary hospitals. It should be strengthen the oversight of radiation workers in nuclear medicine and in primary and secondary hospitals.

OBJECTIVETo study the factors influencing short-term prognosis of tuberculous meningitis (TBM) in children.

METHODSThe clinical data of 137 hospitalized children with TBM between January 2007 and February 2011 were retrospectively reviewed. A total of 30 potential factors influencing short-term prognosis of TBM were evaluated by univariate analysis and multivariate logistic regression analysis.

RESULTSClinical staging showed that of the 137 children 21 cases (15.3%) were in the early stage, 67 cases (48.9%) in the medium stage and 49 cases (35.8%) in the late stage of TBM. The univariate analysis revealed 8 factors associated with a poor short-term prognosis: clinical stage of TBM (late), coma, positive Babinski signs, cranial nerve involvements, paralysis, seizures, obvious abnormalities in brain computed tomography (CT) or magnetic resonance imaging (MRI) and elevated protein concentrations in cerebrospinal fluid (CSF). Factors associated with a favourable short-term prognosis for TBM included glucocorticoid steroids therapy, positive reaction of PPD skin test and an increased length of stay in hospital. Multivariate logistic analysis revealed two independent risk factors for a poor short-term prognosis: clinical stage of TBM (late) (OR: 11.168, 95%CI: 3.521-35.426) and positive signs of meningeal irritation (OR: 4.275, 95%CI: 1.043-17.521). An increased length of stay in hospital was shown as a favorable factor (OR: 0.893, 95%CI: 0.825-0.968).

CONCLUSIONSLate-stage TBM and positive signs of meningeal irritation suggest a poor prognosis, while an appropriately longer length of stay in hospital may contribute to a favorable short-term prognosis for children with TBM.

Objective To investigate the value of the bedside index for severity in acute pancreatitis (BISAP),Ranson's,APACHE Ⅱ and computed tomography severity index (CTSI) scoring system in evaluating the severity of acute pancreatitis.Methods The clinical data of 385 patients with acute pancreatitis who were admitted to the Zhongnan Hospital of Wuhan University from 2005 to 2011 were retrospectively analyzed.The values of 4 scoring systems including BISAP,Ranson's,APACHE Ⅱ and CTSI in predicting the incidences of severe acute pancreatitis,local complications and death were investigated by Chi-square test and receiver operating characteristic curv e.Odds ratio (OR) was calculated.The differences of areas under the curves (AUC) were analyzed using the Z test.Results The incidences of severe acute pancreatitis,local complications and mortality of patients with BISAP score ≥ 3 were 64.4％ (56/87),16.1％ (14/87) and 8.0％ (7/87),which were significantly higher than 13.4％ (40/298),6.4％ (19/298) and 0.3 ％ (1/298) of patients with BISAP score ≤ 2 (x2 =93.4,8.1,19.7,P ＜ 0.05).The incidences of severe acute pancreatitis,local complications and mortality of patients with Ranson's score≥3 were 52.7％ (48/91),22.0％ (20/91) and 7.7％ (7/91),which were significantly higher than 16.3％ (48/294),4.4％ (13/294) and 0.3％ (1/294) of patients with Ranson's score ≤2 (x2 =49.2,27.3,18.5,P ＜0.05).The incidences of severe acute pancreatitis,local complications and mortality of patients with APACHE Ⅱ score ≥ 8 were 46.6％ (27/58),20.7％ (12/58) and 8.6％ (5/58),which were significantly higher than 21.1％ (69/327),6.4％ (21/327) and 0.9％ (3/327) of patients with APACHE Ⅱ score≤7 (x2 =17.0,12.8,14.4,P ＜0.05).The incidences of severe acute pancreatitis,local complications and mortality of patients with CTSI score ≥4 were 51.4％ (19/37),51.4％ (19/37),16.2％ (6/37),which were significantly higher than 22.2％ (77/347),4.0％ (14/347),0.6％ (2/347) of patients with CTSI score≤3 (x2 =15.1,95.3,40.1,P ＜ 0.05).The sensitivity,specificity,positive and negative predictive values of BISAP were 58％,89％,64％,86％,respectively,and the AUC was 0.848,which were significantly higher than the other 3 systems (Z =2.02,4.22,4.78,P ＜ 0.05).The sensitivity,specificity,positive and negative predictive values of CTSI were 58％,95％,51％ and 96％,respectively,and the AUC was 0.926,which was significantly higher than the other 3 systems (Z =3.99,3.24,4.06,P ＜ 0.05).The sensitivity,specificity,positive and negative predictive values of BISAP were 88％,79％,8％ and 100％,respectively,and the AUC was 0.855,with no significant difference compared with the other 3 systems (Z =0.81,0.03,0.14,P ＞ 0.05).Conclusions The accurate rate of BISAP in predicting the severe acute pancreatitis is higher than Ranson's,APACHE Ⅱ and CTSI.The accurate rate of CTSI in predicting the incidence of local complications is higher than the other 3 systems.There is no significant difference of the 4 systems in predicting the mortality.The BISAP scoring system is helpful in early diagnosis of severe acute pancreatitis,and making the individualized treatment plan,thus improving the prognosis of patients.

A novel disposable three electrodes blood alcohol biosensor strip was fabricated by a screen printing technique. Multi-wall carbon nanotube(MWCNT), Meldola′s(MB), alcohol dehydrogenase(ADH)and nicotinamide adenine dinucleotide cofactor (NAD+) were modified on the surface of the carbon working electrode. Then hydrophilic membrane was stuck in the outermost of the three electrodes to make a reaction camera of 5 μL. Experimental results indicated that the biosensor possessed good accuracy and stability, the linear response range was 0.5-20 mmol/L with correlation coefficient of 0.9949, detection limit was 0.22 mmol/L, and the response time was less than 15 s. Some influencing factors to the biosensor were investigated, such as the pH, temperature and interferences. Correlation analysis showed that there was a significant correlation between the methods of biosensor and the headspace vapor phase chromatography in 10 whole blood samples(r=0.97583). Small volume whole blood sucked using siphonage to detect blood alcohol directly and quantitatively was the obvious character of the biosensor.

Iridoid glycosides were the main active ingredient of Rehmannia glutinosa, of which catalpol has the highest content. This work will provide theoretical basis for metabolic study and cultivation of iridoids on the basis of the dynamic accumulation of catalpol and total iridoids in the growth of R. glutinosa. The samples of rehmannia 85-5 were gathered in the same filed from July to October. The contents of catalpol and total iridoid glycosides were measured by HPLC and specteophotometric, respectively. The results showed that youngest leaves had the higher content of catalpol and total iridoid glyosides than that of the other two leaf ages in the same growth stage from July to September, while their content of catalpol and total iridoid glycosides were all decreased as the growth of leaves of R. glutinosa. The content of catalpol didn't differ significantly from July to September, whereas it has significantly increased in October in the three leaf stage. In the same stage, the wider the root diameter is, the higher content of the effective components are. In August and September, the total iridoid glycosides have the fastest accumulation. The content of catalpol was increased as the accumulation of total iridoid glycosides.

Objective To investigate the echocardiographic features and clinical significance of prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC). Methods Fetal echocardiographic images of 13 fetuses with TAPVC conifrmed by pathology or postnatal echocardiography were reviewed. Echocardiographic features and clinical signiifcance of prenatal diagnosis of TAPVC were summarized. Results Twelve fetuses with TAPVC were diagnosed prenatally by fetal echocardiography, including seven cases of supracardiac type, three cases of infracardiac type and two cases of intracardiac type. The common echocardiographic characteristics of 12 fetuses with TAPVC included slightly size discrepancy of left heart and right heart, large foramen ovale with increased shunting at the atrial level, increased distance between left atrium (LA) and descending aorta, absent insertions of pulmonary veins in the LA, presence of pulmonary venous conlfuence on the top of LA and dilatation of vessels where pulmonary venous conlfuence drained. One case was missed prenatally and intracardiac type TAPVC was diagnosed by postnatal echocardiography. Among the 13 cases, three were isolated and the other ten were all in association with other abnormalities. Conclusions There are fetal echocardiographic characteristics of TAPVC. Fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.
