Objective To achieve primary intervention from early on the analysis concerning correlations between BI-RADS classification and the factors that might influence it was conducted. Methods In this paper, the women involved in the 7204 cases of physical examinations in our hospital(over the past 5 years)were chosen as the subjects investigated. The correlations between their breast ultrasounography results and the factors such as age,BMI,triglycerides,total cholesterol,glucose,and uterine status were analyzed. The breast report used the Breast imaging reporting and data system(also known as BI-RADS)of the American Society of Radiology to inter-pret the results. Chi-square test and logistic multivariate analysis of data were analyzed by SPSS 13 statistical soft-ware. Results The age,triglyceride,total cholesterol,HDL and glucose were not the factors influencing BI-RADS classification(P>0.05);BMI(P=0.004)and uterine status(P=0.000)turned out to be the independent factors. Low body weight[odds ratio(OR)= 0.696,95%Confidence interval(CI)= 0.502 ~ 0.966],overweight (OR=0.217,95%CI=0.142~0.333),and obese(OR=0.123,95%CI=0.066~0.231)were negatively correlat-ed with it. Hysterectomy(OR = 19.189,95%CI = 14.055 ~ 26.198),(OR = 4.384,95%CI = 3.499 ~ 5.492), uterine fibroids ,menopausal uterus were found to be the risk factors(OR = 3.283 ,95%CI = 2.374 ~ 4.541). Conclusion For the premenopausal women,being overweight or underweight can help reduce the risk of getting breast diseases. However,those suffering absence of uterus,or uterine fibroids,or in their menopausal period,are supposed to be among the high-risk group of breast cancer for regular screening.

Objective Tongue shape and motion is one of the important references for tongue diagnosis.However, current tongue image objectification of tongue diagnosis cannot express the characteristics of tongue.Methods In order to increase shape and dynamic information about the tongue, the methods of key frame selection and linear interpolation were used to tongue 3D dynamic visualization reconstruction model on the basis of 3D static visual model.For the convenient use of the tongue 3D dynamic visualization model, this paper put forward a model of 3D dynamic visualization interaction system which was realized based on DirectX.Results The 3D dynamic visualization model not only had a static visual model of texture and depth information, but also could intuitively describe the tongue motion.Conclusions It provides a method for the auxiliary tongue diagnosis of traditional Chinese medicine (TCM).

Humans are exposed to the ubiquitous radiofrequency (RF, 100 kHz-300 GHz) electromagnetic fields because of the mushroom development of wireless communications,raising concerns over the possible hazards of RF radiations.Epidemiological investigation has showed that chronic use of cellphones increases the risk of brain tumors.Since genetic damage is closely related to tumors, researchers have been trying to find out whether cellphones and other RF devices are genotoxic.However, the investigations have yielded both negative and positive results.This review summarized the recent in vitro and in vivo researches about genotoxicity of RF radiations and proposed a possible mechanism by which of RF radiations cause genetic damage.

Objective To establish a real-time quantitative polymerase chain reaction (qPCR) assay for B-cell lymphoblastic leukemia according to individualized and specific immunoglobulin gene rearrangements in leukemia cells, and to use it for the monitoring of minimal residual disease (MRD) of B-cell lymphocytic leukemia. Methods The immunoglobulin gene rearrangements of bone marrow samples from 15 cases of B-cell lymphoblastic leukemia were analyzed with a validated European BIOMED-2 system, and the individualized and specific qPCR-based quantification of leukemic immunoglobulin gene rearrangements was established. Results Unique and specific gene rearrangements of immunoglobulin light and heavy chains were identified in 14 cases and Ig-qPCR based on these gene rearrangements had a sensitivity of 10-5 and high specificity which met the international criteria in 10 patients. Leukemia MRD quantification with immunoglobulin gene rearrangement-based qPCR was similar as compared with other MRD detection methods. Conclusion Immunoglobulin gene rearrangement-based leukemia MRD quantification is feasible, sensitive, specific, precise and much valuable for clinical decision of treatments in B-cell lymphoblastic leukemia.

Objective To investigate the current dyslipidemia profiles and correlation with etiological factors in early stage post-transplantation, and the impact of lipid metabolic disorder on renal function. Methods The clinical data of 1032 renal allografts from eight hospitals in Beijing between 2004 and 2008 were collected and evaluated retrospectively. Before and at the 1st, 3rd, 6th and 12th month post-transplantation, the changes in blood total cholesterol (TC), triglycerides (TG),low density lipoprotein (LDL)-cholesterol and high density lipoprotein (HDL)-cholesterol were analyzed. The difference in the blood lipid disorder at different stages stratified by time and different age group, the effects of immunosuppressive agents on blood lipid, and the impact of blood lipid disorder on the blood creatinine were studied. Results Except HDL-cholesterol, TC, LDL-cholesterol and TG levels were increased gradually at the first year, especially LDL-cholesterol and TG. The TC and LDL-choleaterol abnormalities were obviously related with age (P<0. 01 ). The effect of Tacrolimus (Tac)-based immunosuppressive regimen on the lipid metabolic disorder was less than cyclosporine (CsA). At the first year, there was no significant difference in blood creatinine between lipid-lowering treatment and non-lipid-lowering treatment (P>0. 05). For the recipients not subject to lipid-lowering treatment and their TG level higher than the normal at the first month after operation, the creatinine level at the first year was significantly higher than in those with normal TG level (P< 0. 05). Conclusion The lipid metabolic disorder following renal transplantation is a common complication after the first transplant year, and was related with age and immunosuppressive agent regimen. Tac-based immunosuppressive regimen has little effects on the blood lipid metabolism.

OBJECTIVE: To observe the effect and explore the mechanism of Huannao Yicong capsule in treating senile patients with mild cognitive impairment (MCI). METHODS: The investigational drugs were packed by blind method. A randomized, double-blind and controlled trial was conducted on ninety senile patients with MCI. Other forty-five senile healthy persons were recruited to the healthy control group. The ninety senile patients were randomly divided into the Huannao Yicong capsule-treated group (45 patients administered with three Huannao Yicong capsules and two aniracetam capsule analogues) and aniracetam-treated group (45 patients treated with two aniracetam capsules and three Huannao Yicong capsule analogues). Patients in the two groups were treated three times daily for 16 weeks. Memory, traditional Chinese medicine syndrome, cerebral blood flow, free radicals and inflammatory mediators, such as superoxide dismutase (SOD), malondialdehyde (MDA), acetylcholinesterase (AchE), interleukin-1alpha (IL-1alpha) and interleukin-6 (IL-6) were determined before and after the treatment. Blood lipids, including triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A-1 (ApoA-1) and apolipoprotein B-100 (ApoB-100), were detected before and after the treatment. The safety indexes, such as routine tests of blood and urine, hepatic and renal function tests and electrocardiogram (ECG) were taken before and after the treatment. RESULTS: Index score of clinical memory scale in senile healthy people was significantly higher than that in MCI patients before treatment (P<0.01), and the content of AchE, IL-1alpha and IL-6 was obviously lower (P<0.01, P<0.05), the activity of SOD was higher (P<0.05). No significant difference was found in direction memory of clinical memory scale between the two treatment groups. Other index scores of clinical memory scale and traditional Chinese medicine syndrome in patients of Huannao Yicong capsule-treated group were significantly improved as compared with those of the aniracetam-treated group (P<0.05, P<0.01). The blood flow parameters of anterior cerebral artery, posterior cerebral artery and resistant index in patients of Huannao Yicong capsule-treated group were increased significantly (P<0.01, P<0.05). Huannao Yicong capsule could significantly increase the activity of serum SOD and decrease the content of AchE, IL-1alpha and IL-6 (P<0.01, P<0.05), better than aniracetam. Furthermore, Huannao Yicong capsule could significantly improve the blood lipid, such as the level of TG, LDL-C, HDL-C, ApoA-1 and ApoB-100 (P<0.01, P<0.05), and better than aniracetam (P<0.01, P<0.05). No significant changes were found after treatment in safety indexes, such as routine tests of blood and urine, hepatic and renal function tests and ECG. CONCLUSION: Huannao Yicong capsule has better therapeutic effect than aniracetam capsule in treating senile mild cognitive impairment.

Objective To investigate the high sensitive C reactive protein(hs-CRP),homocysteine(Hcy), interleukin 2(IL-2)and lipoprotein associated phospholipase A 2(Lp-PLA2)analysis and correlation test for coronary heart disease.Methods 147 cases were selected from our hospital in December 2015 to December 2016 in patients with coronary heart disease(observation group).At the same time,we selected 51 healthy persons in our hospital during December 2015 to December 2016 as control group.The content of hs-CRP was determined by immune transmission turbidimetry.The content of Hcy was determined by cyclic enzymatic method.The content of IL-2 was determined by enzyme linked immunosorbent assay(ELISA).The content of Lp-PLA2 was determined by immune transmission turbidimetry.Results The observation group serum levels of hs-CRP,Hcy,IL-2 and Lp-PLA2 were significantly higher than those in the control group,and the differ-ence were statistically significant(P<0.05).The coronary heart disease each group serum levels of hs-CRP, Hcy,IL-2 and Lp-PLA2 were significantly higher than those in the control group,and the differences were sta-tistically significant(P<0.05).The serum levels of hs-CRP,Hcy,IL-2 and Lp-PLA2 of AMI group were sig-nificantly higher than those in UAP group and SAP group,and the differences were statistically significant (P<0.05).The UAP group serum levels of hs-CRP,Hcy,IL-2 and Lp-PLA2 were significantly higher than those in SAP group,and the difference was statistically significant(P<0.05).Conclusion Hs-CRP,Hcy,IL-2,Lp-PLA2 have significant correlation with coronary heart disease.

Objective:To investigate the monocyte to high-density lipoprotein cholesterol (HDL-C) ratio (MHR) for the predictive value of early neurological deterioration (END) and poor outcome in patients with acute anterior circulation ischemic stroke (AACIS).Methods:Patients with AACIS admitted to Henan Provincial People's Hospital from January 2021 to January 2022 were included retrospectively. END was defined as the National Institutes of Health Stroke Scale (NIHSS) score within 7 d of onset increase ≥2 compred with baseline or the increase of motor function score ≥1. The patients were divided into END group and non-END group according to the presence or absence of END. The patients were also divided into good outcome group (0-2 points) and poor outcome group (3-6 points) according to the modified Rankin Scale score 3 months after onset. Multivariate logistic regression analysis was used to determine the independent risk factors for END and poor outcome, and the predictive value of MHR for END and poor outcome was evaluated by receiver operating characteristic (ROC) curve. Results:A total of 522 patients were enrolled, including 338 male (64.8%), aged 61.99±11.39 years old. One hundred and five patients (20.1%) had END, 123 (23.6%) had poor outcome. Multivariate logistic regression analysis showed that baseline NIHSS score (odds ratio [ OR] 1.075, 95% confidence interval [ CI] 1.017-1.137; P=0.010) and MHR (with the lowest quartile as the reference, the third quartile: OR 2.778, 95% CI 1.255-6.151, P=0.012; the fourth quartile: OR 12.645, 95% CI 5.942-26.912; P<0.001) were the independent risk factors for END; the baseline NIHSS score ( OR 1.075, 95% CI 1.021-1.132; P=0.006), END ( OR 2.306, 95% CI 1.010-6.261; P=0.047) and MHR (with the first quartile as reference, the fourth quartile: OR 2.769, 95% CI 1.167-6.569; P=0.021) were the independent risk factors for poor outcomes. ROC curve analysis showed that area under the curve of MHR for predicting END and poor outcome in patients with AACIS were 0.805 (95% CI 0.750-0.860; P<0.001) and 0.747 (95% CI 0.690-0.803; P<0.001) respectively. The best cutoff value was 0.435, the sensitivity was 73.3% and 64.2%, and the specificity was 79.6% and 78.7% respectively. The area under the curve of MHR for predicting END and poor outcome was higher than that of monocyte and HDL-C alone. Conclusion:MHR can be used as a predictor of END and poor outcome in patients with AACIS, and its predictive value is higher than that of monocytes or HDL-C.

In recent years, with the change of natural and social factors, such as climate warming, urbanization, land reclamation, human population growth, change of life customs, and convenient transportation, the human infectious diseases transmitted by insect vectors, well known as insect-borne infectious diseases, has increased significantly, causing a serious threat to public health. This paper focuses on the epidemiology, clinical characteristics, especially laboratory diagnosis of insect-borne infectious diseases, and emphasizes that medical institutions should pay attention to the rapid and accurate laboratory diagnosis of insect-borne infectious diseases. Metagenomic next generation sequencing has potential value in the diagnosis of insect-borne infectious diseases with unknown causes.
