Objective To outline the research fronts of ten major sub-specialties in internal medicine.Methods Based on their impact factor scores and the proportion of the journals of 10 subspecialties (endocrinology & metabolism,cardiac & cardiovascular systems,hematology,infectious diseases,nephrology,gastroenterology & hepatology,respiratory system,rheumatology,critical care medicine,clinical neurology) in Journal Citation Report (JCR),and careful consulation of expert clinicians,we identified 50 journals.Their bibliographic records (including references) published in 2011 were downloaded,and the frequency of the references (citations) in each sub-specialty was counted and the highly cited records were extracted.We performed a clustering analysis according to the co-cited times among any pairs of the highly cited records.To tag each cluster of highly cited records,we browsed the titles and abstracts of all highly cited records in the same cluster,and concluded the main topics of each cluster.Finally,we extracted the current published papers devoted to particular cluster by some clustering analysis indicators.The clusters of highly cited records were considered as the intelligence base,and the main topics in current papers which citing these highly cited papers were considered as research fronts.Results Totally 50 journals on 10 sub-specialties in internal medicine were identified.A total of 202 highly cited papers,38 clusters (knowledge bases),and 152 corresponding current citing papers presenting the research fronts were selected.Conclusions We confirm and present research fronts in 10 major sub-specialties of internal medicine.This study provides a synchronic structure of contemporary research activities in internal medicine sub-specialties.

The ergosterols were produced from corn straw hydrolysates fermented by ergosterol yeast,which was obtained from protoplast electrofusion.The effects on the yield of ergosterol were studied in the condition of shaker,such as initial sugar concentration,nitrogen source,pH value and fermentation time.The technical conditions were optimized according to the DPS center-united experimental design principles and the method of response surface analysis with four factors and three levels.The results indicated that the four factors had significant correlation to ergosterol accumulation.The biomass and the ergosterol content could be up to 8.67g/L and 2.37% respectively after cultivated for 32h under optimal technical condition.The structure of ergosterol crystal was characterized by UV,IR and SEM.A new approach of biomass source application was presented.

Objective To observe the effect of human immunoglobulin on elderly head and facial post herpetic neuralgia (PHN) and peripheral blood TNF-α.Methods One hundred and twenty-two inpatients with PHN aged ≥65 years old were selected and divided into the observation group (52 cases) and control group (70 cases) by the systematic sampling method.The control group was given the early conventional combined therapy,while on this basis the observation group was intravenously dripped by human immunoglobulin.The incidence rate of PHN and pain visual analog scale(VAS) score at 1,2,3 months after recovery discharge from hospital were recorded in the two groups.Other 20 healthy elderly people were selected as the healthy control group.The TNF-α level was determined in the two patients groups before and after treatment and in the healthy control group.Results The PHN occurrence rate at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group(P＜0.05);the VAS score after treatment and at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group (P＜0.05);serum TNF-α level after treatment in the observation group was significantly lower than that in the control group (P＜0.01),moreover which was close to the level in the healthy control group(P＞0.5).Conclusion Human immunoglobulin can reduce the PHN occurrence in the old people with head and facial herpes zoster and reduce the peripheral blood TNF-α level.

Objective To detect the changes of the NJ001 specific antigen expression before and after surgery, and evaluate whether the NJ001 specific antigen could be used as a serum biomarker for the diagnosis of pancreatic cancer.Methods With the method of sandwich ELISA, the serum samples from 85 pancreatic cancer patients, 22 pancreatic benign tumor and 40 healthy controls were detected respectively. The results of the NJ001 specific antigen in the serum samples from 85 pancreatic cancer patients were compared with CA19-9 detected by ECLIA.Results The positive rate of NJ001 for the pancreatic cancer group was obviously higher than that for the benign pancreatic tumor and health control groups[50.6%(43/85) vs 18.2%(4/22), χ2 =7.451, P<0.05; 50.6%(43/85) vs 10.0%(4/40), χ2 =19.098, P<0.05].The difference between benign pancreatic tumor group and health control group had no statistical significance[18.2%(4/22) vs 10.0%(4/40),χ2 =0.845, P>0.05].The positive rate in the group of pancreatic cancer before surgery was higher than that after surgery[50.6%(43/85) vs 23.5%(20/85),χ2=13.341, P<0.05].In addition, the results from 85 pancreatic cancer patients showed the specificity of NJ001 specific antigen was up to 87.1%.Although the positive rate of NJ001 specific antigen for pancreatic cancer was lower than that of CA19-9[50.6%(43/85) vs 75.3%(64/85), χ2 =11.121, P<0.05], it was higher when they combined [ 85.9%( 73/85 ) ] .Conclusions It shows high positive rate of NJ001 specific antigen in the patients of pancreatic cancer in this study, which suggests that NJ001 specific antigen might be a potential valuable biomarker for the diagnosis of pancreatic cancer.

We investigated the therapeutic effect of Albizia julibrissin total saponins on mice infected with Trichinella spiralis.Thirty-six ICR mice infected with Trichinella spiralis were randomly divided into 6 groups (each mouse infected with 300 T.spiralis),6 mice in each.Group Ⅰ:infected non-treated group (intestinal phase);group Ⅱ..received Albizia julibrissin total saponins group (intestinal phase);group Ⅲ:received albendazole group (intestinal phase);group Ⅳ:infected nontreated group (muscular phase);group Ⅴ:received Albizia julibrissin total saponins group (muscular phase);group Ⅵ:received albendazole group (muscular phase).Mice of Ⅰ,Ⅱ,Ⅲ group were administered on the second days post-infection(dpi) and continued for 3 days.Mice in these groups were sacrificed 7th dpi and adult worms recovered from the small intestine were counted.Mice of Ⅳ,Ⅴ,Ⅵ group were administered on the 7th dpi and continued for 14 d.The mice were sacrificed on 40th dpi,and the muscle larvae were counted.HE staining counts muscle larvae and the expression of IL-1β,IL-6,TNF-α and COX-2 in the diaphragm were detected by immunohistochemistry.Results showed that the number of adult worms and larva in groups received Albizia julibrissin total saponins and albendazole were significantly lower than that of infected non-treated group (P＜0.01).The worms reduction rate was 70.34％ and 80.02％ respectively,and the larva were 65.60％ and 90.66％ respectively.Results of HE staining showed the number of encysted larval and the expression of inflammatory cell were significantly reduced.The expression of IL-1β,IL-6,TNF-α and COX-2 was decreased in drug-treated groups.In conclusion,the total saponins of Albizia julibrissin showed adequate efficacy on Trichinella spiralis adults and encapsulated larva.Although the effect is slightly inferior to albendazole,as traditional Chinese medicine extract,it is less toxic.

OBJECTIVETo observe the inhibitory effect of targeted ribonuclease delivered via adenovirus against HBV replication in vitro.

METHODSThe shuttle plasmids pDC316 were constructed on the basis of the previous plasmids pcDNA3.1(-)/TRL, pcDNA3.1(-)/TR, pcDNA3.1(-)/TRmut, pcDNA3.1(-)/HBVc, and pcDNA3.1(-)/hEDN by subcloning the target gene sequences of TRL, TR, HBVc, and hEDN, respectively. HEK 293 cells were cotransfected with the pDC316 plasmids respectively in the presence of the rescue plasmid pBHGlox(delta)E1,3Cre to yield the recombinant adenoviral vectors which comprised the above genes. After transfection of HepG2.2.15 cells with the vectors, RAd/TRL expression was detected by indirect immunofluorescence staining and RT-PCR. Radioimmunoassay was used to analyse anti-HBV activity of RAd/TRL.

RESULTSRecombinant RAd vectors were prepared successfully. Effective expression of RAd/TRL in HepG2.2.15 cells resulted in a significant decrease of HBsAg and HBeAg concentration in comparison with the controls.

CONCLUSIONAdenoviral vector-mediated targeted ribonuclease can effectively inhibit HBV replication.

Objective To analyze the data of road traffic accidents, deaths and injuries in 31 provinces and municipalities in China from 2010 to 2017, and to predict that the number of deaths and injuries caused by road accidents set in the sustainable development goals (SDGs) will be halved by 2020 compared with the target set in 2015. Methods Describing and analyzing the current situation of road traffic accidents in 31 provinces and municipalities in China, and using the trend extrapolation method to predict whether the SDGs target can be achieved by 2020. Results The numbers of traffic accidents, deaths and injuries in Guangdong, Jiangsu, Zhejiang and Shandong Provinces showed a downward trend from 2010 to 2017, but still ranked the front in China. In 2017, Beijing had the highest death rate followed by Guizhou as the second, and Guizhou had the highest injury rate followed by Tianjin as the second. The projected results showed that the numbers of deaths and injuries caused by road traffic accidents in China would be increased by 17% and 1.3% respectively in 2020 indicating that SDGs target could not be met. Among the 31 provinces/municipalities, it was predicted that the numbers of deaths and injuries in Hunan would be reduced to 50.7% and 65.3% in 2015, respectively by 2020, and the target could be achieved; the number of injuries in Shanghai was decreased by 83.3%, but the deaths was only decreased by 34.5%, and there was still a gap with the target; the rest 29 provinces/municipalities could not meet SDGs target. It was expected that the deaths in 11 provinces and municipalities would increase by 2020, with Beijing, Jilin, Jiangxi, Hubei and Guizhou Provinces showing the most significant growth. The number of injured people in 8 provinces and municipalities shows an increasing trend, with Jilin, Jiangxi, Hubei and Guizhou provinces showing significant growth. Conclusions Except for Hunan Province, it was difficult for the whole country and the rest provinces and municipalities to reach the SDGs target. According to the forecast results and the actual situation, a targeted scientific prevention and control strategy can be formulated. The measures taken by Hunan and Shanghai in traffic accident prevention and control were effective and worth learning.

Objectvi e To understand the correlation between the diabetes and the complications and the constitution of traditional Chinese medicine ( TCM ) in Baoshan District in Shanghai , and to provide scientific evidence for carrying out the targeted prevention and intervention measures.M ethods TCM body mass table was used to distinguish the TCM constitution of the diabetic patients and the control group .The relationship between TCM constitution and diabetes and its complications was analyzed by single factor and multiple factor logistic regression . Results There were less patients with yin-yang harmony constitution and yang deficiency constitution in the case group than in the control group , while more with qi deficiency constitution and phlegm-damp constitution than in the control group .Among a total of 879 cases of diabetic patients with1 235 physical elements , the top four biased constitution elements were identified including constitution of qi deficiency ( 15.22%), yin deficiency ( 8.42%), yang deficiency ( 8.42%) and phlegm-damp ( 8. 34%).The yin deficiency, qi deficiency and phlegm dampness constitution elements in the case group were significantly higher than in the control group .Among 875 cases in the control group with 1 129 physical elements , the top four biased constitution elements were yang deficiency (12.40 %), qi deficiency( 9.65%), yin deficiency (5.05%) and phlegm-damp (4.52%), which yin-yang harmony constitution and yang deficiency constitution elements were significantly higher than those of the case group .The incidence of complications of the diabetic patients with biased constitution was significantly higher than those with the yin-yang harmony constitution . Conclusion Phlegm dampness constitution , qi deficiency constitution and yin deficiency constitution are the main dangerous constitution of diabetes mellitus .The protective constitution of diabetes is yin-yang harmony constitution and yang deficiency constitution .The biased constitution elements are the risk factors of diabetes complications .
