100 u/L 24 months later and another 38 year-old patient underwent surgical operation of ovaries bilaterally before UAE. Conclusions Temporary amenorrhea may not mean ovarian dysfunction or failure. The probability of ovarian dysfunction or failure after UAE is low, which mainly occur in the peirmenopausal patients. Consideration of the probability of inducing early ovarian failure, caution should be taken for UAE on the patients having ovarian surgery before. (J Intervent Radiol, 2006, 15: 472-475)

The aim of this study is to establish stable transfected cell lines which could produce SPAG4L protein labeled with Myc and His tags in vitro. The open reading frame (ORF) of human SPAG4L was amplified by PCR and the fragments were cloned into eukaryotic expression vector pcDNA3.1/myc-His(-)A. The recombined plasmids of pcDNA3.1/myc-His(-)A/SPAG4L were verified by sequencing and digestion with enzymes. Then, the recombined plasmids were introduced into HeLa cells and screened by G418. Western blotting was performed to detect the expression of SPAG4L and its tags in stable transfected cell lines. SPAG4L and its tags were expressed in the stable cell lines transfected with pcDNA3.1/myc-His(-)A/SPAG4L, but not in the control group. Further study showed that SPAG4L colocalized with the endoplasmic reticulum(ER) marker PDI by immunofluorescence. The stable transfected cell lines established in this study will provide a powerful tool for further studies such as co-immunoprecipitation and pull-down.

Objective To analyze the effect of Chinese diabetes risk score in health checkup of elderly population and to explore the risk factors of abnormal glucose metabolism in the elderly patients.Methods Chinese diabetes risk score(C-DRs)screening,glucose tolerance test(OGTT),blood biochemical parameters and history collection were performed in 1 181 elderly people participating the health checkup.The area under the ROC curve(AUC)was used to evaluate the accuracy of the screening method.The effect of different cumulative C-DRs on screening target population was reflected by the Gordon index.Multivariate logistic regression analysis was used to analyze relevant risk factors for the glucose metabolic abnormalities.Results The AUC of screening for diabetes was 0.749(95%CI:0.715-0.782),and the best cut-point value was 32.5 points.The sensitivity was 86.50%,the specificity was 60.84%,and the Gordon index was 0.47(P=0.000).The AUC of screening for the pre-diabetes was 0.760(95%CI:0.733-0.787),and the best cut-point was 33.5 points.The sensitivity was 70.89%,the specificity was 68.72%,and the Gordon index was 0.40(P=0.000).The AUC of screening for MS was 0.797(95% CI:0.772-0.823),and the best cut-point value was 32.5 points.The sensitivity was 83.62%,the specificity was 64.90%,and the Gordon index was 0.49(P=0.000).The AUC of screening for insulin resistance was 0.609(95%CI:0.645-0.734),and the best cut-point value was 30.5 points.The sensitivity was 81.25%,the specificity was 44.81%,and the Gordon index was 0.26(P=0.000).Multiple logistic regression analysis showed that age over 80 years,abdominal obesity(waist circumference,male ≥ 90 cm,female ≥ 85 cm),hypertension,hypertriglyceridemia,family history of diabetes were risk factors for abnormality of glucose metabolism in the elderly.The odd ratio values of the above were 1.557,1.543,1.495,1.569,1.625,1.715(all P<0.05).Conclusions Chinese diabetes risk score may be used to screen for diabetes,metabolic syndrome and insulin resistance in the elderly population.Old age,abdominal obesity,hypertension,hypertriglyceridemia and family history of diabetes are independent risk factors for abnormal glucose metabolism in the elderly population.

Objective To identify and analyze the homology of Ochrobactrum isolated from clinical blood samples of children.Methods The 26 strains of Ochrobactrum anthropi were identified by Vitek 2 Compact and test strips of API 20 NE bacterial identification system.The biochemical phenotypes were identified by manual tests.The 16S rRNA and recA gene were amplified by PCR and sequenced.The drug sensitivity tests of Ochrobactrum anthropi were performed by Vitek 2 Compact and matched GN13 card.The homology was analyzed by pulsed field gel electrophoresis.Results Based on the identification of the instruments and the manual tests for biochemical phenotype,all the 26 experimental strains were Ochrobactrum anthropi.The results of sequencing for 16S rRNA and recA gene amplification products showed 25 strains were Pseudochrobactrum saccharolyticum and the other 1 was O.grignonensein.Drug sensitivity analysis showed that the all the 26 strains were resistant to aztreonam,but the sensitive rates to quinolones,aminoglycosides,trimethoprim sulfamethoxazole,four generation of cephalosporins and the antibiotics compound of piperacillin/tazobactam were all more than 80％.Pulsed field gel electrophoresis analysis showed that the 25 strains were highly homologous with differences of only 1 to 3 bands in fingerprint profiles.Conclusion Based on the biochemical phenotype and the sequencing of 16S rRNA and recA gene,the Ochrobactrum-like bacteria could be identified to the level of species.The highly homologous strains of Pseudochrobactrum saccharolyticum may be sourced from a clustered infection.

Objective To explore the clinical characteristics of treatment?resistant depression ( TRD) and of its relevance with thyroid hormones. Methods 43 patients with TRD and 48 patients with non?TRD were as?sessed with 17?item Hamilton depression scale ( HAMD?17) and Hamilton anxiety scale ( HAMA) . The serum lev?el of thyroid?stimulating hormone ( TSH) ,total triodothgronine ( TT3) ,total thyroxine ( TT4) ,free triodothgronine ( FT3) and free thyroxine ( FT4) were determined by radioimmunoassay. χ2 test and t test were used for statistic a?nalysis. The quantitative relation of FT3 level with TRD was analyzed and the value of FT3 level in TRD diagnosis was evaluated by ROC curve.Results Compared with non?TRD patients,the TRD patients showed a younger dis?ease onset age ((16.98±2.25)years vs (23.50±3.38)years) and a longer disease course ((10.14±6.47)years vs (5.48±4.15)years) for total disease course;(60.35±23.64)months vs (5.00±3.40)months for current disease course),and had shorter education years ((8.53±1.72)years vs (11.04±2.07)years) and higher HAMD total scores (19.09±1.59 vs 15.69±2.38) and behavior retarding factor scores (8.72±0.98 vs 4.98±1.63). In addition, the FT3 level of TRD patients was lower than that of non?TRD patients ((3.92±0.15)pmol/L vs (4.16±0.20) pmol/L).All the above differences between two groups were statistically significant (P<0.05). The logistic regres?sion analysis showed that the risk of suffering TRD increased by 1. 006?fold when FT3 level reduced 0. 1 pmol/L (OR=2.006,95%CI=(1.501,2.681). The area under ROC curve was 0.821 (P<0.001) with its 95% confidence interval of (0.734,0.907). Conclusion Compared with non?TRD patients,TRD patients have a longer disease course,a younger disease onset age, a lower education level, higher HAMD total scores, more severe retardation symptoms,and a lower FT3 level. The serum FT3 level has a high reference value in diagnosis of TRD.

Objective To detect the expressions of osteopontin (OPN) and inerleukin-18 in patients with bullous pemphigoid (BP),and to analyze their relationship with clinical and laboratory indices.Methods Enzyme linked immunosorbent assay (ELISA) was performed to quantify the serum levels of osteopontin (OPN) and inerleukin (IL)-18 in 30 patients with BP and 30 health controls.Results The serum level of OPN was statistically higher in the patients than in the healthy controls ((8.29 ± 2.76) vs.(3.88 ± 1.41 ) ng/ml,P ＜ 0.01 ),and was positively correlated with the severity of BP (r =0.658,P ＜ 0.01 ) and with some laboratory indices in the patients.Increased serum IL-18 level was observed in patients complicated by cardiovascular diseases compared with those without cardiovascular diseases ((37.49 ± 6.43) vs.(31.10 ± 5.40) pg/ml,P ＜ 0.01).Moreover,the BP patients with diabetes,tumor,hepatic and renal impairment displayed an enhanced level of serum OPN and IL-18 than those without (all P ＜ 0.05).Conclusions OPN may be positively correlated with the severity of BP,while IL-18 may be involved in the development of complications of BP.

Objective To explore the features of sustained attention in the patients with social anxiety disorder and their first degree relatives.Methods 60 cases of normal controls,58 cases of patients with social anxiety disorder and 68 cases of their first degree relatives were performed with continuous performance test.Results In reaction time task(a simple performance),all of CPT parameters in patient group (number of cancel (5.2±6.9),number of omission(6.7± 13.6),reaction time(421.0± 112.0) ms,variance coefficient(47.3±38.1) ％)were higher than those in the first degree relatives group(number of cancel (2.9± 3.3),number of omission (1.5±2.1),reaction time (342.0±47.0) ms,variance coefficient(28.9± 10.1) ％) and controlled group (number of cancel (2.8 ± 2.9),number of omission (1.3 ± 0.7),reaction time (329.0 ± 53.0) ms,variance coefficient (27.8± 9.7) ％),the differences were significant(P＜0.01),while all of CPT parameters in the first degree relatives were similar to those in controlled group(P＞0.05).In X task (a complex performance),the results of CPT in the first degree relatives were between the patients and the normal controls,and the differences were statistically significant(P＜0.05).Conclusion The anxiety disorder patients showed no sustained attention impairment in simple performance while in a complex performance there were some defects of sustained attention functions in the patients with social anxiety disorder and their first degree relatives.

Purpose: This study aimed to investigate sub-health status (SHS) of people living in China during the Coronavirus disease 2019 (COVID-19) COVID-19 pandemic. COVID-19 is a severe acute respiratory syndrome coronavirus (SARS-CoV) infection-induced acute infectious disease, which is featured by universal susceptibility and strong infectivity, and SHS (a status of low quality health) refers to a status of low-quality health. COVID-19 has gradually developed into a global pandemic, making the public in a high stress situation in physiological, psychological and social states in the short term. Methods: From March 6 to 11, 2020, a large-scale cross-sectional survey was conducted by convenient sampling, and SHS assessment scale was used in the questionnaire. The ordinal logistic regression analysis was used to identify the factors affecting SHS. Results: In this study, 17,078 questionnaires were delivered with 16,820 effective questionnaires collected, and 10,715 subjects (63.7%) were found with SHS, with moderate SHS primarily. Physiological sub-scale scored the highest, followed by psychological and social sub-scales. Ordinal logistic regression analysis indicated that man, only-child, workers and farmers were risk factors of SHS. Protective factors of SHS included living in rural areas and townships, laid-off retirees and education degree. Conclusion It shows many people in China place in a poor health status during COVID-19 pandemic. It is necessary that relevant departments pay more attention to people with poor health such as men, only-child, urban people, workers and farmers, and groups with high education degree during and after pandemic stabilization.

Objective:To investigate the clinicopathological features of fumarate hydratase (FH) deficiency uterine leiomyoma.Methods:The data of 38 patients with FH deficiency uterine leiomyoma were screened and analyzed. The expressions of FH, S-(2-succino)-cysteine (2SC), desmin, p16, p53, CD 10 and cell proliferation associated nuclear antigen (Ki-67) proteins were detected by immunohistochemistry, and their clinicopathological features were analyzed retrospectively. Results:(1) Clinical features: the median age of the patients was (42.5±7.4) years old. Twenty-one cases (55%) of them were myomas found in physical examination, and the median maximum diameter of the tumor was 6.0 cm (range: 5.0-7.5 cm); myomectomy was performed in 23 cases (61%), total hysterectomy with or without bilateral appendages in 15 cases (39%); laparoscopic surgery in 27 cases (71%), open surgery in 11 cases (29%); none of the patients had renal cell carcinoma. (2) Histological features: atypical nuclear cells were distributed locally or diffusely, eosinophilic nucleoli and intranuclear inclusion bodies could be seen, glass like globules could be seen in the cytoplasm, nuclear division was 0-4/10 high power field (HPF), and antler like blood vessels and pulmonary edema-like changes could be seen in the stroma. Among 38 patients with FH deficiency uterine leiomyoma, FH was negative in 37 cases (97%), and positive in 1 case (3%); 2SC, desmin, p16, p53, CD 10 and Ki-67 showed focal positive expression in 38 cases (100%), including 35 cases (92%) with Ki-67 index<10% and 3 cases (8%) with Ki-67 index ≥10%. (3) Follow-up: 4 cases (11%) recurred, and there was no death. There were significant differences in age, family history, distribution of atypical nuclei and mitosis number between recurrent group and non-recurrent group (all P<0.05). Conclusions:FH deficiency uterine leiomyoma is a rare tumor, which needs pathological examination,immunohistochemical examination and clinical history. Patients younger than 43 years old, with family history, histologically atypical diffuse nuclear distribution and mitotic number ≥3/10 HPF should be alert to the risk of recurrence.
