Objective: To compare the difference of infrared radiation temperature on body surface of points between healthy people and patients with hyperplasia of mammary glands. Method: The thermaCATMT P30 infrared thermal imaging system was selected to measure the infrared radiation temperature on body surface of eight points in four meridians in 74 patients with hyperplasia of mammary glands and 63 healthy people. Results: The infrared radiation temperatures on body surface of right Youmen (KI 21) in cases with hyperplasia of mammary glands were significantly higher than the healthy people (P=0.009), and the infrared radiation temperatures on left Youmen (KI 21) and other points had no significant difference with healthy people (P>0.05). Conclusion: The infrared radiation temperatures on body surface of right Youmen (KI 21) have significant differences with healthy people. This might occur because of the pathogenesis of hyperplasia of mammary glands and of the specificity of the point Youmen (KI 21).

Objective:To evaluate the qualitative and quantitative diagnostic value of transvaginal contrast-enhanced ultrasonography for benign and malignant adnexal masses.Methods:Forty-nine patients with adnexal masses detected by routine ultrasound examination at Wenzhou People's Hospital from January 2021 to December 2022 were included in this study. Initially, transvaginal two-dimensional ultrasound, two-dimensional ultrasound integrated with color Doppler, and contrast-enhanced ultrasonography were used to accurately classify the masses as benign or malignant. Using postoperative pathology as the gold standard, the qualitative diagnostic accuracy of various detection methods was compared. Subsequently, the receiver operating characteristic curve analysis was performed to assess the quantitative diagnostic accuracy of transvaginal contrast-enhanced ultrasonography-related parameters in distinguishing between benign and malignant adnexal masses.Results:Among the 49 patients, 10 were diagnosed with malignant tumors. The diagnostic accuracy of contrast-enhanced ultrasonography was 93.88% (46/49), with a sensitivity of 90.00% (9/10), a specificity of 94.87% (37/39), a positive predictive value of 81.82% (9/11), and a negative predictive value of 97.37% (37/38). The results of the diagnostic difference assessment (McNemar test) revealed that there was no significant difference between two-dimensional ultrasound ( χ2 = 0.37, P = 0.546), two-dimensional ultrasound combined with color Doppler ( χ2 = 0.17, P = 0.683), and contrast-enhanced ultrasonography ( χ2 = 0.00, P = 1.000), and the gold standard test results. The consistency assessment (Kappa test) revealed that the diagnostic results of contrast-enhanced ultrasonography exhibited the highest concordance with the gold standard, with a Kappa value of 0.82 ( P < 0.001). Furthermore, the receiver operating characteristic curve analysis indicated that the initial increase time, peak intensity, and mean transit time in contrast-enhanced ultrasonography demonstrated high quantitative diagnostic accuracy. The areas under the curve were 0.83, 0.82, and 0.84, respectively, and the diagnostic cutoff values were 17.30 s, 21.65 dB, and 92.60 seconds, respectively. Conclusion:Contrast-enhanced ultrasonography exhibits diagnostic value in the differential diagnosis of benign and malignant adnexal masses, both qualitatively and quantitatively. This method can provide valuable insights for further treatment.

Objective To explore the application effect of self-made micro-video in practical teaching of mental and psychological nursing.Methods Two classes in major Nursing enrolled in 2013 were selected randomly. A total of 51 students from Class 12 were designated as the experimental group, and were taught assisted by self-made micro-videos, while another 53 students from Class 11 belonged to the control group, and were taught assisted by traditional instructional video. The students were surveyed by questionnaire on knowledge awareness rate on mental disease prevention, regulated in mental health work index investigation and evaluation scheme, formulated by General Office of National Health and Family Planning Commission of the People's Republic of China, basing on which, teaching effect was compared.Results After practical teaching, total accuracy rate of case examination by students in the experimental group was 94.12% (compared with 39.22% before the practice), and in control group, 81.13% (compared with 33.96% before the practice). Scores of attitude towards mental disease in the experimental group were (54.39±4.68), and in the control group (35.15±7.69) (t=15.49, P<0.01).Conclusions Applying self-made micro-video in practical teaching of mental and psychological nursing can effectively improve accuracy rate of mental disease recognition of the students, correct their attitude towards patients with mental disorders, with satisfying effect in practice.

Objective:To evaluate the differences and aesthetic meaning of stable vitiligo treatment in the face and neck region using suction blister transplantation or noncultured autologous suspension of epidermal cells.Methods:Sixty-four stable vitiligo patients (25 males and 39 females with age ranges from 10 to 46 years, average 25 years) in the face and neck region were randomly divided into two groups (32 patients in each group): one group received suction blister transplantation, while other group received noncultured autologous suspension of epidermal cells. Patients′treatment effectiveness, pigmentation and piecing deformity were evaluated in postoperative 3 months and 6 months.Results:In the postoperative 3 months and 6 months, the effectiveness of suction blister transplantation group was 68.75% (22/32) and 90.63% (29/32), respectively, while the effectiveness of noncultured autologous suspension of epidermal cells group was 59.37% (19/32) and 87.50% (28/32), respectively, in which no significant differences were found between two groups ( P>0.05). No obvious pigmentation and piecing deformity were found in noncultured autologous suspension of epidermal cells group, which were much better than the suction blister transplantation group in postoperative 3 months and 6 months. Conclusions:Both suction blister transplantation and noncultured autologous suspension of epidermal cells could bring good treatment effectiveness for patients of stable vitiligo in the face and neck region. Compared with suction blister transplantation, noncultured autologous suspension of epidermal cells could offer better aesthetic appearance.

Objective To investigate the clinical effect of Qiji Zhuyu Zhixue decoction in treatment of previous cesarean scar defect(PCSD)and explore the value of transvaginal two-dimensional ultrasound combined with three-dimensional power Doppler ultrasound(3D-PDUS)in the diagnosis of PCSD.Methods A total of 120 PCSD patients treated and treated in Wenzhou People's Hospital from April to October 2023 were selected as study objects,and they were randomly divided into case group(50 cases)and control group(70 cases).The case group was treated with Qiji Zhuyu Zhixue decoction,and the control group was treated with desogestrel and ethinylestradiol tablets.The clinical effects after 6 months of treatment were compared between two groups.The length,width,depth,lateral muscle thickness and volume of PCSD before and after treatment were evaluated by two-dimensional ultrasound combined with 3D-PDUS.The receiver operating characteristic curve was used to evaluate the efficacy of ultrasonic parameters in diagnosis of PCSD.Results After 6 months of treatment,the total effective rate of case group was significantly higher than that of control group(x2=21.97,P＜0.01).After treatment,the diverticulum depth and volume in case group were significantly lower than before treatment(P＜0.05).The diverticulum depth in case group was significantly lower than that in control group(P＜0.05).The lateral muscle thickness in case group was significantly greater than that before treatment and control group(P＜0.05).The area under the curve of the combined diagnosis of PCSD with diverticular depth,diverticular lateral muscle thickness and diverticular volume was 0.707.Conclusion The clinical effect of Qiji Zhuyu Zhixue decoction on PCSD is remarkable.Transvaginal two-dimensional ultrasound combined with 3D-PDUS is the first choice for the diagnosis of PCSD,and it is worth popularizing and applying.
