BACKGROUND: Quality of life, which is induced as a completely evaluating system to reflect new healthy viewpoints and medical patterns, plays a key role in supplying traditional therapy and evaluating rehabilitation efficacy in occupational injury.OBJECTIVE : To analyze the effects of occupational injury on quality of life in mining area of Tongling, Anhui.DESIGN: Case contrast questionnaire, Logistic single factor analysis and multiple factors analysis.SETTING: Workers General Hospital of Tongling Nonferrous Metal Group; Mining Safety Office of Tongling Nonferrous Metal Company.PARTICIPANTS: A total of 234 subjects with occupational injury were selected from four subgroups of Tongling Nonferrous Metal Company from January 2000 to December 2005 and regarded as the occupational injury group.Injured grade was evaluated by the department of safety in production. In addition, 206 employees of the same sex were regarded as the control group. All subjects provided the confirmed consent.METHODS: Questionnaires were finished in December 2006. Besides those whose educational level was lower than primary school or illness state was severe, their questionnaires were filled by somebody else through asking the feelings,and other subjects filled in the questionnaires by themselves. ① Social demography characteristics were surveyed in the two populations. ② The World Health Organization Quality of Life Assessment-100 (WHOQOL-100), which was characterized by excellent reliability, validity and sensitivity, was used to survey influencing factors (sex, age, occupation,educational level, marriage, smoking, drinking, pay, type of work in production, grade of occupational injury, injured site and type, other diseases, average income of per family member, housing area of per family member, accidental types,character styles, sleeping status, etc.) and various dimensions reflecting quality of life [physiological function (body ache,vigor, sleeping), mental state (well-being feels, confidence, and other three aspects), independence (daily living ability,work ability, and other two aspects), social relationship (interpersonal relation, social communication, and other one spect), material life (reliability, housing environment, and other eight aspects) and faith (individual faith)]. There were 24 aspects and every aspect included four items; in addition, there were 4 items in general healthy status. Therefore, there were 100 items in total. LinearitY method was used to score each item (from 1 tc 5 points). Self-scored quality of life had only one item, which was scored based on hundred-mark system. ③ Quality of life of subjects in the occupational injury group was analyzed with one-way analysis of variance. Variously dimensional indexes of quality of life in 6 fields were regarded as dependent variance, and effect factors were regarded as independent variance. The data were analyzed with multiple stepwise regression analysis.MAIN OUTCOME MEASURES: ① Characteristics of social demography; ② scores of variously dimensional indexes of quality of life; ③ correlation between quality of life and effect factors in occupational injury group.RESULTS: All 234 patients in the occupational injury group and 206 subjects in the control group were involved in the final analysis. ① There were no significant differences in sex, age, occupation, educational degree, working duty,marriage, drinking, smoking, pay, having other diseases and occupational types between the two groups (P ＞ 0.05). ②Scores of physiological field, independence field and total quality of life were lower in the occupational injury group than those in the control group (P ＜ 0.05). ③ Effect factors on quality of life in the occupational injury group contained intoxication and asphyxia; ankle, foot and cranial injuries; avulsed wound and task degrees. Multiple factor analysis demonstrated that quality of life of patients in the occupational injury group was affected by waist injury, pay level and relationship with colleagues and family member.CONCLUSION: Quality of life is inferior in the occupational injury group to that in the control group. The effect factors are mainly focus on injured sites, accident and injured types, economic status and relationship with society and family member.

Objective To elucidate the changes of the peripheral blood B cells in acquired immunodeficiency syndrome (AIDS) patients after the initiation of the highly active antiretroviral therapy (HAART ) ,and to investigate the effect of B cell count on the curative effect of HARRT .Methods Fifty‐three cases of AIDS outpatients and 26 healthy controls were collected between April 2011 and December 2014 . CD4+ T and B lymphocytes counts were compared between the two groups before HAART treatment ,3 ,6 and 12 months after the treatment .The correlation between ΔCD4+ T cells andΔB cells (i .e .the difference value of CD4+ T cells and B cells before HAART treatment and after 12‐month treatment , respectively ) were analyzed . According to whether the CD4+ T lymphocyte count increased by 100/μL after 1 year of the first HAART ,patients were divided into treatment response and nonresponse groups .B cell counts were compared between the two groups ,and the most suitable B cell count to initiate HAART was identified by mean of receiver operating characteristic (ROC) curve .Pre‐and post‐treatment results were compared by paired samples t test .Comparison of measurement data between multiple groups were analyzed by one‐way ANOVA analysis .Correlation between the two groups were analyzed by Pearson correlation analysis .Results B cell counts of AIDS patients before treatment ,3 ,6 and 12 months after treatment were (115 .0 ± 41 .0)/μL ,(130 .3 ± 54 .1)/μL ,(154 .2 ± 68 .1)/μL and (193 .9 ± 84 .0)/μL ,respectively ,while the B cell count of healthy controls was (299 .4 ± 125 .1)/μL . Significant differences among the five groups were observed (F= 24 .8 ,P< 0 .01) .Increases of the B lymphocyte counts with varying degrees were observed after treatments ,which were slow in the initial 3 months and faster afterwards .ΔCD4+ T cell was positively correlated with ΔB cell (r= 0 .493 , P<0 .05) .The B cell counts before treatment in the treatment response and nonresponse groups were (130 .6 ± 40 .4)/μL and (87 .2 ± 24 .5)/μL ,respectively ,which was significantly different (t=4 .77 ,P<0 .05) .The area under the ROC curve was 0 .848 .If the B cell count before treatment was 99 .5/μL ,the sensitivity and specificity to predict effective treatment were 82 .4% and 84 .2% , respectively . Conclusions B cell counts increase with varying degrees during HAART .B cell count before treatment can predict the therapeutic effect of HAART .

Objective To assess the association between polymorphisms in HIF1α gene and prognosis of advanced hepatocelluar carcinoma.Methods We collected prognosis data from a cohort of 448 advanced HCC patients treated by transarterial chemoembo-lisation,and used 5ml peripheral blood from patients for extraction DNA.Three SNPs (rs2301 1 13、rs2057482 and rs1 957757 )in HIF1αgene were selected and genotyped.Multivariate Cox proportional hazards model,Kaplan-Meier curve and log-rank test were used for prognosis analyses.Results The variant-containing genotypes (WV+VV)of SNP rs2301 1 13 exhibited a significant associ-ation with a better overall survival in HCC patients who had tumor size smaller than 5 cm (hazard ratio [HR],0.58,95% confidence interval [CI],0.35-0.96,P =0.036).In the patients taken single tumor subgroup,the variant-containing genotypes (WV+VV) of SNP rs2301 1 13 exhibited a significant association with a better overall survival (log-rank P =0.048),comparing to those carrying wild-type genotype.Conclusion Our results suggest that polymorphisms in HIF1αgene may serve as an independent prognosis bio-marker for advanced HCC patient.

Objective To explore the morphological characteristics and change rule of thoracic joint angles in children aged from 10 to 12 years through thinner CT scanning and 3D reconstruction,and to provide theoretical basis for early diagnosis,treatment and prevention.Methods Totally 30 normal cases aged from 10 to 12 years were admitted into this study.There was no bone destruction,deformity,fractures,tumors and spine surgery involved.DICOM 3.0 data of multi-slice spiral CT (0.625 ～ 1.25 mm),ranging from T1 to T12,were used for 3D reconstruction,measurement and statistical analysis.Results The difference between left and right sagittal section angle of zygopophysis was less than 10°.There was no significant differences between T1,T11,and T12for sagittal section angle of upper zygopophysis (P ＞ 0.05).So was it between T3,T4,T9,T10 and T11 for sagittal section angle of lower zygopophysis (P ＞ 0.05).While there were significant differences between others(P ＜ 0.05).The was no significant difference between left and right coronal plane angle of zygopophysis (P ＞ 0.05).Coronal plane angle of lower and upper zygopophysis tended to be ‘ spike-like’,and the maximum points were at T7 to T9.For horizontal plane angle,left and right upper zygopophysis made significant differences between T2,T4,T8,T10 and T12 only,so did T7 lower zygopophysis (P ＜ 0.05).Horizontal angle of upper zygopophysis tended to be stable in the upper thoracic both in the left and right side,while a decreasing trend was shown in lower thoracic.Horizontal angle of lower zygopophysis showed a decreasing trend generally except individual vertebrae.Both upper and lower zygopophysis showed negative angle at T11 and T12 levels.Conclusion Thoracic joint angles(coronal,sagittal and horizontal angle) in children aged from 10 to 12 years can directly reflect the developmental regularity with growth,and it verified the tendency that horizontal facet joints of the cervical spine gradually changes to coronal facet joints thoracic spine and then changes to sagittal facet joints of lumbar spine.And the left and right side facet joints are basically symmetrical with the angle difference less than 10°.

Objective To provide regional anatomical data for clinical application through observing the type, length and diameter of variation in the medial cubital vein of upper limb. Methods Dissected the medial cubital vein of upper limb in 35 (70 sides) adult cadavers (male 38, female 7), and observed the morphological structure. The length and vessel diameter of the medial cubital vein were measured. Results The variation of the medial cubital vein of upper limb was divided into six type.

Conclusion This study enriched anthropology data of the medial cubital vein and it has the role of guiding in clinical applications.

Multi-Efficacy of One Drug (MEOD) refers to the traditional Chinese medicines (TCM) with diverse efficacies.MEOD,one of the important characteristics of TCM,is regarded as the basis of clinical rational drug use.However,there have been few reports on the MEOD research so far.In this paper,with rhubarb selected as a typical model drug,metabolomics and network pharmacology analysis are integrated to investigate the mechanisms of MEOD with the employment of the two animal models of constipation and jaundice.Then,the biological target network of MEOD is established for promoting the precision of the quality control and clinical use of TCM.

Objective To investigate the effects of transarterial chemoembolization (TACE)treatment interval on the prognosis of patients with advanced hepatocellular caisinoma(HCC).Methods We retrospectively collected clinical data of 123 advanced HCC patients treated with repeated TACE.The patients were divided into two groups (group A with fixed repeated treatment interval and group B with that according to the clinical needs).Cox regression,survival curve and log-rank test were used to assess the effects of the treat-ment intervals on prognosis.Results The treatment intervals of the group A and group B were (1.1±0.3)months and (3.0±1.5) months,respectively (P <0.001).Multivariate Cox analysis showed the efficacy (P =0.024)and repetition periods (P <0.001 ) were independent prognostic factors.Conclusion TACE interval is independent risk factor for the prognosis of patients with ad-vanced HCC.Repeated TACE treatment according to clinical needs may be more favorable for prognosis of the patients.

Objective The correlation analysis was proceeded between youth cervical hook and transverse foramen by using imaging scanning and three-dimensional reconstruction method,which can provide theoretical basis for early diagnosis,treatment and prevention of ju-venile cervical spondylosis.Methods A total of 66 teenagers who had no trauma,neurological symptoms or signs were selected with aged from 6 to 20 years old,who were scanned by multi slice spiral CT,ranged from C1 to T1 .The original data in DICOMformat to import 3D re-construction software was related index measurement and subsequent statistical analysis.Results There was a correlation between hook height,base width,base length of luschca joint and transverse diameter,longitudinal diameter.Conclusion Hook vertebral meridian of lus-chca joint and transverse foramen has a close contact.Factors such as fracture and hyperplasia of luschca joint,vertebral artery of transverseforamen can be oppressed that cause corresponding vertebral artery type of cervical spondylosis.

BACKGROUND:With the change of modern living habits, the incidence of cervical disease and cervical related diseases is increasingly at younger age. Based on this feature, the discussion of the relationship between the cervical spine and vertebral body as wel as regular feature can provide theoretical basis for early diagnosis, prevention and treatment of cervical spondylosis. OBJECTIVE:To analyze the correlation structure of the cervical vertebra uncinate process with the vertebral body and intervertebral foramen among adolescents. METHODS:A total of 66 cases without injuries, neurological symptoms or signs of 6 to 20 years old were scanned with multi-row thin-slice spiral CT from C1-T1. The original data were loaded in DICOM format into three-dimensional reconstruction software for measurement and statistical analysis. RESULTS AND CONCLUSION:(1) In addition to uncinate process height and vertebral body height, the uncinate process spacing, uncinate base width and diameter between the vertebrae and a uncinate process base radius vector length and vertebral bodies were positively correlated (P<0.05). (2) Uncinate high uncinate base long uncinate base width and height between the foramen in addition to the uncinate process had a positive correlation with the length of the substrate (P<0.05). (3) In conclusion, there is a certain correlation in juvenile cervical uncovertebral joint between the uncinate process and vertebral body and intervertebral foramen. With the growth of age, cervical activity is increased and the uncinate hyperplasia, trauma, and fracture can oppress spinal nerve within the intervertebral foramen to cause corresponding nerve root type of cervical spondylosis.

OBJECTIVETo analyze the epidemiology data on plague in five counties in Zhejiang province and to evaluate the risk of plague in theses areas.

METHODSWe selected five monitoring stations as a risk assessment (Qingyuan county, Longquan city, Yiwu city, Wencheng county, and Ruian city) in Zhejiang province where the plague epidemic more serious in the history. At least one constant site and 1-4 variable sites where plague occurred in history were selected for monitoring. We collected the five counties (cities) surveillance data of indoor rat density, indoor Rattus flavipectus density, the Xenopsylla cheopis index of rat, the Xenopsylla cheopis index of Rattus flavipectus in 1995-2014. Isolation of Yersinia pestis was conducted among 171,201 liver samples and F1 antibody were detected among 228,775 serum samples. Risk matrix, Borda count method, and Delphi approach were conducted to assess risk of the plague of five counties (cities) in Zhejiang province.

RESULTSIndoor rat density in Qingyuan county, Longquan city, Yiwu city, Wencheng county, Ruian city was 1.58%-5.50%, 1.13%-9.76%, 0.56%-3.67%, 2.83%-16.08%, 7.16%-15.96%, respectively; Indoor Rattus flavipectus density of five counties (cities) was 0.08%-2.23%, 0-2.02%, 0-0.54%, 0.71%-5.58%, 0.55%-4.92%, respectively. The Xenopsylla cheopis index of rat in Qingyuan county and Wencheng county was 0.011-0.500 and 0.015-0.227, respectively; The Xenopsylla cheopis index of Rattus flavipectus of Qingyuan county and Wencheng county was 0.119-3.412 and 0.100-1.430, respectively; Ruian City and Yiwu city cannot collected Xenopsylla cheopis, Long quan city only collected the Xenopsylla cheopis index of rat in the five years. Yersinia pestis were not isolated in five counties (cities).There were 3 Apodemus agrarius samples positive of plague F1 antibody test, in Longquan city and Yiwu city in 2005. Borda count method to assess the Longquan city, Yiwu (Borda point were both 321) plague risk was higher than three other regions; Delphi approach to evaluation five counties (cities) belong to the plague had a lower risk areas, according to the level of risk score (Pf) Longquan city and Yiwu (Pf was 0.314, 0.292, respectively) plague risk were higher than three other regions (Pf were all 0.292).

CONCLUSIONThe main host and media were lower in five key plague surveillance counties (cities) of Zhejiang province; The result of Borda count method and Delphi approach for risk assessment indicated that endogenous plague recrudescence was at lower level, but Longquan city and Yiwu city risk were higher than other counties (cities).
