Purpose:To study the value of high frequency color doppler ultrasound diagnosis for breast intraductal papilloma.Methods:50 patients with breast intraductal papilloma,all confirmed by surgical and pathology,and examined by ultrasound before surgery,all had symptoms of excreting blood or liquid from nipple or palpable mass. The probe were placed on the surface of the breast to scan radially from nipple,after finding the enlarged duct,try to detect the neoplasm in it carefully. The two dimensional images were observed and the color Doppler flow codes were detected.Results:The detection rate and the diagnostic accuracy rate of breast intraductal papilloma by ultrasound are 62.0% and 38.0% respectively,ultrasonography is better than mammography and near infrared light scanning.The images were divided into four types:one type of no unusual finding(7 cases),one type of finding both the enlarged duct and the tumor(19 cases),one type of finding the enlarged duct only(12 cases),one type of finding the tumor only(12 cases),the images of the type of finding both the enlarged duct and the tumor are typical. The detection rate of flow by color doppler ultrasound is low(5/50).Conclusions:The high frequency color doppler ultrasound is valuable in diagnosis of breast intraductal papilloma,and the special symptom ,the accurate detection method and the typical images are the key of ultrasound diagnosis.

Objective: To explore the effect of anxiety, depression, perceived social support on maternal-fetal attachment (MFA) in women during late pregnancy. Method: A sample of 207 cases of women during late pregnancy was assessed with Maternal Antenatal Attachment Scale, Perceived Social Support Scale and Hospital Anxiety and Depression Scale. Results: Anxiety and depression scores were negatively correlated with MFA scores (r=-0.401,-0.416, P<0.01); perceived social support scores were negatively correlated with anxiety and depression (r=-0.233,-0.362, P<0.01), but positively correlated with MFA scores (r=0.200, P<0.01). The interactive effects of anxiety×perceived social support and depression × perceived social support on MFA were significant(β=0.196、0.204, P<0.01). Conclusion Perceived social support played a moderating role between negative emotion and MFA.

A sub-microsecond pulse generation applied for electroporation effects of tumor cell is presented in this paper. The principle of the generator is that the expected pulse waveform is intercepted from the RC discharge curve by controlling the on-off states of two IGBT modules with a synchronous controller. Experimental tests indicate that the generator can produce adjustable pulse waveform parameters with 0.5-3.5kV amplitude, 300-800 ns pulse duration, 1-400Hz repetition frequency rate, and it is suitable for the study of the electroporation effect experiments.

Objective:To investigate the status of family function of patients after hysterectomy, explore the effect of self-concealment on family function.Methods:From January to November 2021,the 177 patients after hysterectomy in Guangdong Provincial People ′s Hospital were investigated by General Data Questionnaire, Family APGAR Indexand Self-Concealment Scale (SCS), and the influencing factors of family function were analyzed by univariate analysis and binary logistic regression. Results:The total score of APGAR and SCS was 9.00 (6.50, 10.00) and 24.00 (17.00, 33.00) after hysterectomy. Univariate analysis showed that marital status, working conditions and tendency of self-concealment were the influencing factors of family function. In the regression analysis of binary Logistic, tendency of self-concealment( P<0.01) and marital status ( P<0.01) entered the regression equation. Conclusions:The family function of patients after hysterectomy is generally good, and self-concealment is a risk factor. It is suggested that in clinical work, attention should be paid to the tendency of self-concealment in patients after hysterectomy, and targeted intervention measures should be taken to improve their family function.

Nuclear envelope voltages of T cells were analyzed with a lumped circuitry for cells in combination with frequency domain power density of Gaussian pulses and monocycle pulses. According to the differences in geometric and electric parameters between normal and malignant T cells, circuitry analysis was performed. Theoretical evaluations indicated that apoptosis of malignant T cells was of feasibility, which could be applied in cancer therapy. The evaluations were in accord with the published experimental findings.

OBJECTIVE To investigate the protective effect and potential mechanism of Arisaema Cum Bile on acute liver injury induced by carbon tetrachloride （CCl4） in mice. METHODS Fifty mice were randomly divided into normal group， model group， positive control group （Biphenyl diester dropping pills， 150 mg/kg）， Arisaema Cum Bile low-dose and high-dose groups （0.78， 2.34 g/kg）， with 10 mice in each group. The mice in each group were given relevant medicine intragastrically， once a day， for 7 consecutive days. Two hours after the last administration， those groups were given intraperitoneal injection of 0.2% CCl4-olive oil solution to induce acute liver injury model except for normal group. Seventeen hours after intraperitoneal injection， the serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interleukin-6 （IL-6）， tumor necrosis factor-α（TNF- α）， and malondialdehyde （MDA）， superoxide dismutase （SOD） in liver tissue were measured with kit method. The hepatic index was detected. The pathological changes of liver tissue were observed by HE staining， and the degree of liver injury was scored quantitatively. The mRNA expressions of TNF-α and IL-6 in liver tissue were detected by real-time fluorescence quantitative PCR； the protein expressions of Janus kinase 2 （JAK2）， signal transducer and activator of transcription protein 3 （STAT3） and nuclear factor-κB p65 （NF-κB p65） in liver tissue were detected by Western blot assay. RESULTS Compared with normal group，the levels of ALT， AST， IL-6， TNF-α and MDA， the hepatic index were increased significantly （P＜0.05）， while the level of SOD was decreased significantly （P＜0.05）； the mRNA E-mail：qhwang668@sina.com expressions of IL-6 and TNF-α， and the protein expressions of JAK2， STAT3 and NF-κB p65 were up-regulated significantly （P＜0.05）； the pathological observation of liver tissue showed that the structure of hepatic cord was seriously disordered， there were many inflammatory cells infiltration of liver cells， and the liver injury score was significantly increased （P＜0.05）. Compared with model group， pathological changes and above indexes in mice were improved significantly in Arisaema Cum Bile low-dose and high-dose groups （P＜0.05）. CONCLUSIONS Arisaema Cum Bile has a protective effect on CCl4-induced acute liver injury in mice， which may be related to the inhibition of inflammatory response mediated by JAK2/STAT3/NF-κB signal pathway and antioxidant stress.

OBJECTIVE To investigate the improvement effects of Arisaema Cum Bile on Parkinson’s disease （PD） model mice and its potential mechanism. METHODS Sixty male C57BL/6J mice were randomly divided into normal group， model group， Arisaema Cum Bile low-dose group [0.39 g/（kg·d）]， Arisaema Cum Bile high-dose group [1.56 g/（kg·d）] and positive control drug Levodopa tablet group [80 mg/（kg·d）]， with 12 mice in each group. Except that normal group was given constant volume of normal saline， other groups were given 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine [MPTP，35 mg/（kg·d）] intraperitoneally for 5 consecutive days to induce subacute PD model； after modeling， they were given relevant medicine continuously for 7 d； rod climbing test and line suspension test were performed 1 d before modeling， on the 5th day of modeling and after the last medication. The number of tyrosine hydroxylase （TH）-positive neurons in the substantia nigra of mice were measured by immunofluorescence； the levels of interleukin 1β （IL-1β） and tumor necrosis factor α（ TNF-α） in serum and the levels of IL- E-mail：qhwang668@sina.com 1β， TNF-α， cyclooxygenase-2 （COX-2） and inducible nitric oxide synthase （iNOS） in the substantia nigra of mice were measured by enzyme-linked immunosorbent assay. The expression levels of cAMP-dependent protein kinase catalytic subunit α （PKA C-α）， glutathione peroxidase 4 （GPX4） and ferritin heavy chain polypeptide 1 （FTH1） proteins in the substantia nigra of mice was measured by Western blot. RESULTS After last medicine， compared with the normal group， mice in the model group had significantly longer pole-climbing time （P＜0.01）， significantly lower line suspension scores （P＜0.01）， significantly fewer TH-positive neurons in the substantia nigra （P＜0.01）， significantly higher serum concentrations of IL-1β and TNF-α and nigrostriatal concentrations of IL-1β， TNF-α， COX-2 and iNOS （P＜0.01）， while lower protein expression levels of GPX4， PKA C-α and FTH1 in the substantia nigra （P＜0.05 or P＜0.01）. Compared with the model group， the above indexes of mice were significantly returned in Arisaema Cum Bile high-dose group （P＜0.05 or P＜ 0.01）. CONCLUSIONS Arisaema Cum Bile can improve motor impairment and reduce apoptosis of nigrostriatal TH neurons in MPTP-induced PD mice， and has neuroprotective effects on model mice； this may be related to its inhibition of neuroinflammation and the inhibition of ferroptosis by up-regulating PKA signaling pathway.
