Objective To assess the value of ultrasonic elastography in the diagnosis of special type breast cancers. Methods Routine ultrasonograms, color Doppler flow images and elasticity images of 13 patients with special type breast cancer confirmed surgical pathologically were retrospectively analyzed. Results The score of mucinous carcinoma, inflammatory breast cancer (1 patient), lactation breast cancer, invasive micropapillary carcinoma, tubular carcinoma and invasive lobular carcinoma (2 patients) were 4-5. The score of 1 patient of invasive lobular carcinoma was 1 and 1 patient of lactation breast cancer was 3. The characteristics of color Doppler flow imaging of majority patients were varies, while no obvious lesion was observed in Paget's disease. Conclusion Ultrasonic elastography is helpful to the diagnosis of inflammatory breast cancer, lactation breast cancer, invasive micropapillary carcinoma of the breast, papillary carcinoma and tubular carcinoma of the breast. Early diagnosis of Paget's disease still depends on pathology.

The association between autoimmunity and lymphoma is bidirectional: patients with autoimmune disorders have an increased risk of developing malignant lymphoma, and autoimmune symptoms occur in the context of malignant lymphoma much more often. The epidemic features, clinical characteristics,and biologic mechanisms that underlie this association have been investigated in many studies, and this review is focused on recent progresses in this area.

Objective To investigate the change and clinical significance of thyroid CT value in patients with Graves disease and Hashimoto' s thyroiditis (HT).Methods One hundred and twelve Graves patients (GD group),54 HT patients (HT group) and 36 healthy people (NC group) were selected as our subjects.Computed tomography (CT) value of thyroid were measured.Results The CT value of the left thyroid gland was (70.53 ± 15.44) Hu in GD group,while (70.50 ± 16.01) Hu at the right side.In HT group,the CT value of the left thyroid gland was (53.77 ± 4.88) Hu,and (52.38 ± 6.67) Hu at the right side.The CT value of the left and right sides was (99.66 ±9.80) Hu and (100.77 ± 10.66) Hu in the NC group respectively.The CT value of GD and HT group were lower than that of the NC group (P ＜ 0.01),and the CT value of the HT group lower than that of the GD group more significant (P ＜ 0.01).Conclusion (1) The CT value of the GD group and the HT group are significantly lower than the NC group and the CT value of the HT group reduces more apparently than that of the GD group.(2) CT values can be used as an early,non-invasive diagnosis of GD and HT secondary indexes.

The validity and reasonableness of emotional data are the key issues in the cognitive affective computing research. Effects of the emotion recognition are decided by the quality of selected data directly. Therefore, it is an important part of affective computing research to build affective computing database with good performance, so that it is the hot spot of research in this field. In this paper, the performance of two classical cognitive affective computing databases, the Massachusetts Institute of Technology (MIT) cognitive affective computing database and Germany Augsburg University emotion recognition database were compared, their data structure and data types were compared respectively, and emotional recognition effect based on the data were studied comparatively. The results indicated that the analysis based on the physical parameters could get the effective emotional recognition, and would be a feasible method of pressure emotional evaluation. Because of the lack of stress emotional evaluation data based on the physiological parameters domestically, there is not a public stress emotional database. We hereby built a dataset for the stress evaluation towards the high stress group in colleges, candidates of postgraduates of Ph. D and master as the subjects. We then acquired their physiological parameters, and performed the pressure analysis based on this database. The results indicated that this dataset had a certain reference value for the stress evaluation, and we hope this research can provide a reference and support for emotion evaluation and analysis.

Objective To explore the difference in pain threshold between related acupoints and the specificity of acupoints in cholecystitis patients.Method Actual measurement was made in 80cases, a normal group of 30 cases (volunteers without psychological and physiological diseases) and a patient group of 50 cases (volunteers with cholecystitis). The probe of an algometer was perpendicularly placed on the selected acupoint, the pressure point was pushed and pressing was stopped immediately after the subject felt pain. The pain thresholds displayed by the measured acupoints were recorded. The pain thresholds of the selected acupoints were compared between the normal and patient groups and thedifferences were analyzed to explore the specificity of acupoints.Result A comparison of the pain thresholds of the Back-Shu points of the Bladder Meridian of Foot-Taiyang between the patient and normal groups showed that there were no significant differences in the thresholds of the left Back-Shu points Geshu (BL17), Ganshu (BL18), Danshu (BL19), Pishu (BL20), Weishu (BL21) and Dachangshu (BL25) of the bladder meridian between the two groups (P>0.05) and there were significant differences in the thresholds of the right Back-Shu points Geshu, Ganshu, Danshu, Pishu, Weishu and Dachangshu of the bladder meridian between the two groups (P<0.01). The pain threshold was significantly lower in thepatient group than in the normal group. A comparison of the pain thresholds of the main points of the Liver Meridian of Foot-Jueyin, the Gallbladder Meridian of Foot-Shaoyang and the stomach meridian between thepatient and normal groups showed that there were significant differences in the thresholds of the right points Liangmen (ST21), Riyue (GB24) and Qimen (LR14) of the liver, gallbladder and stomach meridians (P<0.01) and no significant difference in the threshold of the right point Taichong (LR3) between the two groups (P>0.05). The pain thresholdwas significantly lower in thepatient group than in the normal group. There were no significant differences in thethresholds of the left points Liangmen, Riyue, Qimen and Taichong of the Liver Meridian of Foot-Jueyin, the Gallbladder Meridian of Foot-Shaoyang and the stomach meridian between the patient and normal groups (P>0.05).Conclusion The pain sensitivity of ipsilaterali related acupoints increase and the relative specificity of acupoints exist in cholecystitis patients.

Objective To explore the effectiveness and precision of 3D printing navigational template in puncturing of foramen rotundum for radiofrequency thermocoagulation to treat primary trigeminal neuralgia (V2).Methods Forty-three patients (27 males,16 females,aged 45-85 years,ASA grade Ⅰ or Ⅱ) with primary trigeminal neuralgia (V2) were included and randomly divided into experimental group (group A,n=21) and control group (group B,n=22).After taking a CT scan and 3D reconstruction of each patient's skull,puncture simulations were carried out,then the final puncture schemes were decided.In group A,puncture was performed under guidance of navigational template but was conducted empirically in group B.In both groups,3D-CT image and electrical stimulation were used in all the procedures to confirm the location of point of needle before radiofrequency thermocoagulation.The cases of successful puncture in one-time,times of CT scanning,radiant quantity,operation time during the operation in both groups were recorded.Furthermore,NRS scores and complications including hypoesthesia,motor function degeneration,hematoma,absence of corneal reflex,cerebrospinal fluid leakage were recorded after procedure.Results The rate of successful puncture in one-time of group A was superior than that of group B (90.4% vs.22.7%).Compared with group B,CT scan times [(1.1±0.3) times vs.(2.8±1.3) times],radiant quantity [(323.1±108.7) mGy*cm vs.(787.8±355.7) mGy*cm],operation time [(15.3±5.5) min vs.(28.5±6.5) min] in group A were significantly reduced (P<0.05).NRS scores of both two groups were obviously reduced after surgery [group A: (3.1±1.7) scores vs.(8.5±0.7) scores;group B: (3.1±1.5)scores vs.(8.5±0.7) scores] (P<0.05),but the effectiveness in group A was not superior than group B.No serious complications occurred in all patients.Conclusion On the basis of sufficient preoperative planning of puncture approach,3D printing template can significantly enhance the effectiveness and precision of puncture of foramen rotundum,improving the efficiency and quality of radiofrequency treatment of primary trigeminal neuralgia (V2).

Rat hepatic oval cell model was induced by hyperglycemia and streptozotocin in vivo. Expression of insulin and mRNA expression of pancreatic transcription factors(Nkx6.1, PDX-1) were carried out. It showed that under high glucose, liver tissues were positive for insulin staining, the expression of Nkx6.1 and Pdx-1mRNA was significantly enhanced, and insulin-1mRNA was found to be expressed. The result suggests that under high glucose, hepatic oval cells can differentiate into insulin-producing cells.

OBJECTIVE To investigate the antibiotics resistance and the presence of resistant gene of Staphylococcus aureus isolated from nosocomial infection patients in our hospital.METHODS Antibiotic susceptibility tests were conducted by Microscan WalkAway-40,the antibiotics resistant genes of aac(6')/aph(2″),aph(3')-Ⅲ,ant(4',4″),TEM,tetM,macA,erm and qacA/B of 16 MRSA and 24 MSSA strains were detected by PCR.RESULTS The percentage of MRSA in this investigation was 59.4%,the positive rate of ?-lactamases of 192 S.aureus strains was 98.9%,resistant rate of S.aureus to ?-lactam antibiotics was 52.1-99.0%,and to erythromycin,clindamycin,clarithromycin,ciprofloxacin,norfloxacin,gentamicin and tetracycline was 52.1%,78.1%,85.5%,56.3%,61.1%,55.2%,and 69.8%,respectively,but to nitrofurantoin and sulfamethoxazole/trimethoprim were relatively lower(1.1% and 10.5%) than the others.VISA,h-VISA and VRSA were not measured.To the most of antibiotics,the resistant rate of MRSA was higher than MSSA.The presence of resistant gene of MRSA and MSSA was different.There was more positive percentage of gene in MRSA than in MSSA.CONCLUSIONS Antibiotics resistance of S.aureus isolated from nosocomial infection patients in our hospital is severe.Compared to MSSA,MRSA has higher antibiotic resistant rate and more complicated drug-resistant mechanism.Some measures should be done to reduce the antibiotic resistance of S.aureus.
