Objective To evaluate the application value of elastic index difference (EID) in identifying benign or malignancy masses of breast imaging reporting and data system (BI-RADS) 3-5.Methods Data of 193 lesions in 164 patients with ultrasonic diagnosed as BI-RADS 3-5 breast masses were retrospectively analyzed.All the cases were confirmed pathologically.The EID of masses and normal glands were measured with elastography quantitative analysis software.BIRADS 3-5 breast masses were diagnosed as malignant when EID≥2.5,which was the criteria for BI-RADS reclassification.ROC curve was drawn,and the area under the curve (AUC) was calculated.The diagnostic accuracy and AUC of malignant breast tumors with the methods of BI-RADS and BI-RADS combined with EID were compared.Results Taking pathological results as gold standard,the sensitivity,specificity,accuracy of BI-RADS in detecting malignant tumors were 96.00％ (72/75),67.80％ (80/118),78.76％ (152/193),and those of BI-RADS combined with EID were 97.33％ (73/ 75),83.05％ (98/118),88.60％ (171/193),respectively.The AUC of BI-RADS combined with EID (0.931) was higher than that of BI-RADS (0.875;Z=2.06,P＜0.05).The statistical difference of accuracy was found between BI-RADS and BI-RADS combined with EID methods (x2 =15.21,P＜0.05).Conclusion The combination of BI-RADS and EID is better than simple using BI-RADS in identifying benign or malignancy of breast tumors.

Objective To investigate the effect of nimodipine (ND) injecting into cisterna magna on the mitochondrial pathway in hippocampus in rabbit model of subarachnoid hemorrhage (SAH). Methods Eighteen New Zealand white rabbits were randomly allocated to Sham group, SAH group and ND group, six in each group. All the animals underwent operation under anaesthesia. One mL/kg autologous non-heparinized arterial blood was injected into cisterna magna in SAH group and ND group, and the same dosage of saline was injected into cisterna magna in Sham group. Thirty minutes after injection, 1 mg/kg nimodipine was injected into cisterna magna in ND group, and equal-volume of saline was injected into cisterna magna in Sham group and SAH group. All the animals were assessed for the grade of food intake and neurological impairment, and rats were killed 72 hours after SAH. Their hippocampus were processed for detecting the expressions of Bcl-2, Bax, Caspase-3 and Cyt-C mRNA by qRT-PCR. The protein expressions of Caspase-3 and Cyt-C were detected by Western blot assay. Results Compared with the Sham group, there were lower grade of food intake, varying degrees of neurological impairment and lower ratio of Bcl-2/Bax, while the mRNA levels of Bcl-2, Bax, Caspase-3 and Cyt-C and protein levels of Caspase-3 and Cyt-C showed elevated expressions in SAH group and ND group (P<0.05). Compared with SAH group, there were no significant differences in the score of food intake and neurological impairment in the ND group ( P>0.05). There were higher ratio of Bcl-2/Bax and expression levels of Bcl-2 mRNA and lower expression levels of Bax mRNA, Caspase-3 and Cyt-C mRNA and proteins in ND group than those in SAH group (P<0.05). Conclusion Nimodipine plays a protective role in inhibiting the activity of mitochondrial pathway in hippocampus after subarachnoid hemorrhage.

Objective:To investigate the immune response characteristics of helper T cells Th1, Th2, Th17 and their related cytokines in acute, chronic and recovery phases after Brucella infection. Methods:Using prospective study, a total of 130 patients with brucellosis in the First Affiliated Hospital of Medical College of Shihezi University from January 2017 to December 2018 were selected as the research subjects, including acute phase group (49 cases), chronic phase group (44 cases), recovery phase group (37 cases), and 30 cases of healthy physical examination during the same period were included in the control group. The peripheral blood samples of all subjects were collected, and flow cytometry was used to detect Th1, Th2 and Th17 cells in the peripheral blood; the cytometry bead array (CBA) was used to detect the serum cytokines interferon-γ (IFN-γ), interleukin (IL)-4 and IL-17A expression levels.Results:In the control, acute phase, chronic phase and recovery phase groups, the differences of the expression ratios of Th1 [(1.03 ± 0.85)%, (5.46 ± 3.54)%, (4.48 ± 2.26)%, (2.29 ± 2.25)%], Th2 [(4.72 ± 2.36)%, (7.00 ± 3.14)%, (13.99 ± 9.14)%, (5.89 ± 4.69)%], and Th17 cells [(2.09 ± 0.48)%, (3.04 ± 2.17)%, (3.61 ± 2.67)%, (2.74 ± 2.58)%] were statistically significant ( F = 20.95, 21.15, 2.90, P < 0.05). Compared with the control group, the expressions ratio of Th1, Th2, Th17 cells in acute and chronic phase groups and Th1 cells in recovery phase group were significantly higher ( P < 0.05); compared with the recovery phase group, the expressions ratio of Th1, Th2 and Th17 cells in acute and chronic phase groups were significantly higher, but the expression ratio of Th2 cells in acute phase group was lower than that in chronic phase group ( P < 0.05). The expression levels of IFN-γ, IL-4, and IL-17A in serum of control group, acute phase, chronic phase and recovery phase groups were significantly different ( F = 7.79, 15.85, 7.55, P < 0.05); compared with the control group, the expression levels of IFN-γ, IL-4, IL-17A in acute and chronic phase groups and IFN-γ, IL-4 in recovery phase group were significantly higher ( P < 0.05); compared with the recovery phase group, the expression levels of IFN-γ, IL-4, IL-17A in acute phase group and IFN-γ, IL-17A in chronic phase group were significantly higher ( P < 0.05). The expression ratio of Th1 cells in recovery phase patients who finished treatment for less than 12 months was significantly higher than that of recovery phase patients who finished treatment for ≥12 months ( t = 2.26, P < 0.05). Conclusions:After patients are infected with Brucella, Th1 cell immunity is dominant in acute phase, Th2 cell immunity is dominant in chronic phase, and there is no significant difference in the response of Th17 cell immunity between acute and chronic phases. The immune function of patients in the recovery phase may still be abnormal when the treatment time is less than 12 months. Some clinically cured patients in the recovery phase still have a relatively high proportion of Th1 cells, suggesting that the patient's immune function has not fully recovered.

Objective:To investigate the changes of left ventricular mass index(LVMI),plasma brain natriuretic peptide (BNP),interJeukin-6(IL-6)and interleukin-10(IL-10)in patients with congestive heart failure(CHF),and their values in risk stratification and prognostic evaluation of CHF thereof.Methods:Ninety-five patients with CHF in accordance with 2001ACC/AHA guidelines were enrolled and stratified as stage A(n=21),B(n=23),C(n=31)and D(n=20).The levels of plasma BNP,IL-6 and IL-10 were measured and compaired with those in 20 healthy subjects(control group).The patients were followed up every three months in two years.The end point was the rehospitalization and the cardiac death.Results:(1)The level of LVMI increased early in patients with CHF at stage B.(2)The plasma BNP levels were initially elevated in CHF patients at stage B,and the concentrations of BNP closely paralleled disease severity.(3)The levels of plasma IL-6 and IL-10 were increased,and the ratio of IL-10/IL-6 was decreased,with the progression of CHF at stage C and D.The plasma BNP level was positively correlated with the levels of IL-6 and IL-10.(4)The new CHF stratification was surperior to NYHA functional classification in regard to CHF prognosis prediction.(5)Multivariate COX regression analysis showed the levels of BNP and IL-6 were the independent risk factors in prognostic evaluation(P＜0.01,P=0.026).(6)Patients in high-risk groups stratified by the combination of BNP and stage classification had obviously higher end point events rate.Conclusion:(1)LVMI was a better marker for the evaluation of left ventrieular remodeling.(2)The intrinsic mechanism of CHF progression was inflammatory reaction deterioration.(3)BNP was a good marker in predicting onset and prognosis of CHF.The combination of BNP and the stage classification could improve the prognostic evaluation in patients with CHF.

Objective:To identify the biotypes of blood culture positive Brucella in patients with acute brucellosis in Xinjiang Uygur Autonomous Region (hereinafter referred to as Xinjiang), and to learn about the clinical characteristics of these patients. Methods:Among the 30 patients diagnosed with acute brucellosis in First Affiliated Hospital, School of Medicine, Shihezi University from January 2019 to July 2021, the positive strains of blood culture Brucella of 12 patients with acute brucellosis were used to identify the biotype by AMOS-PCR. Then the general and clinical data of the 12 patients were collected, including demographic characteristics, epidemiological characteristics, clinical characteristics, laboratory tests, treatment and prognosis. Results:AMOS-PCR results showed that all 12 strains were Brucella melitensis. Among the 12 patients, 9 were males and 3 were females, all of whom had a clear history of livestock contact, and the onset time was concentrated in April to September. All 12 patients showed fever, followed by headache and dizziness (9/12), weakness (8/12), digestive symptoms (8/12), hyperhidrosis (7/12), lumbago and backache (6/12), and arthralgia (6/12). One patient was complicated with pleural effusion and pericardial effusion. One patient was complicated with pleural effusion, pelvic effusion and ascites. Only ascites occurred in 2 patients. Liver function was abnormal in 3 patients, lactate dehydrogenase increased in 6 patients, and blood creatinine decreased in 9 patients. Among the 12 patients, 10 patients were treated with rifampicin combined with doxycycline. The other 2 patients were treated with levofloxacin and doxycycline, supplemented by symptomatic treatment with hepatoprotective drugs due to impaired liver function. After discharge, the patients received out-of-hospital oral anti-infectious drugs for 1-2 courses (6 weeks each course), and all indicators returned to normal at 6 months and 12 months after discharge. Conclusions:All the 12 patients with acute brucellosis in Xinjiang are infected with Brucella melitensis. In addition to the common clinical features, patients are characterized by decreased creatinine and increased lactate dehydrogenase. The standardized anti- Brucella treatment is still the main treatment strategy.
