Conclusion Testicular torsion is easily misdiagnosed,color doppler ultrasound should be preferred.Early diagnosis and aggressive surgical exploration,unity and strictly control the orchiectomy surgery indications,means a lot to reduce the rate of orchiectomy.

Objective To investigate DSA- estimated hepatic arterial hemodynamics of hepatocellular carcinoma (HCC) determined shortly after transcatheter arterial chemoembolization (TACE) plus sorafenib treatment. Methods The clinical data of thirty HCC patients treated with TACE were retrospectively analyzed. The patients were divided into study group (n = 13) and control group (n = 17). Patients in the study group received additional oral administration of 400mg sorafenib twice a day one week before or two weeks after TACE procedure, while patients in the control group received TACE only. The initial DSA images as well as the images obtained at three months after TACE were analyzed. With the help of Photoshop software, the grey gradient of the tumor staining was measured on the series dynamic DSA images, based on which the time- density curve of the tumor was drawn. The peak density value (PV), the time to reach the peak (TP) and the slope of the upslope (SU) were determined, and the results were compared between the two groups. Results Photoshop software was used to measure the grey density values of the tumor staining on DSA images. In the study group, the post- treatment PV was smaller than the pre- treatment one, which were (38.0 ± 14.6) and (46.7 ± 18.4) respectively, the difference between the two groups was statistically significant (P = 0.040). The post- treatment PV of the study group was also smaller than that of the post -treatment PV of the control group (54.4 ± 19.8), and the difference between the two was also statistically significant (P = 0.011). No significant differences in TP values and SU values existed between the two groups as well as between the pre - treatment and post - treatment ones in each group. Conclusion After TACE.

Abstract: Objective　To explore the carrying status of four common deafness genes and mutations on 10 loci in newborns in Hainan, and to analyze the molecular epidemiological characteristics of deafness genes and their loci, so as to provide scientific basis for formulating neonatal deafness gene screening strategy and promoting children's hearing health in Hainan. Methods　Newborns born in Hainan from January 2020 to December 2021 were selected as the research objects. The demographic characteristics of the research objects were collected. At the same time, the plantar blood of newborns was collected, and multiplex PCR amplification and directed hybridization combined with high-throughput sequencing technology were applied to detect 10 mutation loci on 4 common deafness genes. T-test or chi square test was used to process the data. Results　A total of 7 124 newborns were included in the study through informed consent, 219 cases of deafness gene mutation were detected with the detection rate of deafness gene of 3.07%. The detection rates of GJB2, SLC26A4, MT-RNR1 and GJB3 were 1.56% (111/7 124), 1.18% (84/7 124), 0.21% (15/7 124) and 0.11% (8/7 124) respectively. Among the 10 loci of the four genes, the positive detection rate of c.235delC locus of GJB2 was the highest, which was 1.38% (98/7 124), followed by c.919-2A>G of SLC26A4 (0.87%, 62/7 124); 2.63% (113/4 289) of the newborns who passed the preliminary hearing screening still carried the deafness gene; in terms of gene type, the detection rate of GJB2 gene in newborns who failed the hearing screening was higher than that in newborns who passed the hearing screening [2.23% (63/7 124) vs 1.12% (48/7 124)，P<0.01]; in terms of gene loci, the detection rate of c.235delC locus in newborns who failed hearing screening was higher than that in newborns who passed hearing screening [2.09% (59/7 124) vs 0.91% (39/7 124)，P<0.01]. Conclusion　The most common deafness genes types in Hainan were GJB2 and SLC26A4; The most common gene mutation sites were c.235delC and c.919-2A>G; 2.63% of the newborns who passed the preliminary hearing screening still carried the deafness gene, among which the high-risk newborns with MT-RNR1 and GJB3 genes were found. Therefore, hearing screening should be combined with deafness gene screening to improve the detection rate of children at high risk of hearing loss.

Objective:To investigate the diagnostic value of conventional endoscopy (CE) and endoscopic ultrasonography (EUS) for invasion depth prediction of superficial gastric cancer.Methods:A total of 84 patients with superficial gastric cancer underwent both CE and EUS before treatment at Beijing Shijitan Hospital from January 2011 to December 2019. The patients were divided into CE affirmation group (47 cases) and CE non-affirmation group (37 cases) according to the endoscopist′s affirmation in the results of CE. Diagnostic accuracy of each method was compared with the histology of the resected specimen. And influential factors for the diagnosis were analyzed.Results:The overall accuracy in determining the invasion depth of superficial gastric cancer was 73.8% (62/84) for CE and 81.0% (68/84) for EUS respectively ( P=0.092). In CE affirmation group, the diagnostic accuracy of CE was significantly higher than that in the CE non-affirmation group [93.6% (44/47) VS 48.7% (18/37), χ2=21.656, P<0.001]. Twenty (23.8%) of 84 lesions were over-staged by CE, dignosed as surgical candidates, and 8 (40.0%) of the over-staged diagnosis were modified by additional EUS assessment. Multivariate logistic analysis showed that influential factors associated with observer affirmation included uneven surface of lesion ( OR=5.076, 95% CI: 1.628-15.821, P=0.005), margin elevation ( OR=3.831, 95% CI: 1.238-11.857, P=0.020) and undifferentiated carcinoma ( OR=6.887, 95% CI: 1.882-25.204, P=0.004). Conclusion:For patients of CE affirmation in the invasion depth, the diagnostic accuracy is high. For those of non-affirmation, additional EUS can improve the diagnostic accuracy and help to develop a more appropriate regime.

Objective To investigate the acute toxicity, subacute toxicity, nasal membrane local toxicity of the Magnolia biondii Pamp volatile oil nanometer bangosome. Methods Kunming mice and SD rats were selected as experimental material. Kunming mice were used in the acute and subacute toxicity tests by intragastric administration of Magnolia biondii Pamp volatile oil nanometer bangosome with different dosage and different time, and SD rats were used in the nasal membrane local toxicity test by nose dropping, while the control group was treated with intragastric administration of or nose dropping with normal saline for the same dosage. The treatment course lasted fifteen days. At the end of the tests, the general condition, routine blood test, function index of live and kidney, organ humid weight index, histological changes of liver and kidney and ultra microstructure change of rat nasal membrane were obtained and compared with the control group. Results In the acute toxicity test, the daily maximum tolerant dosage by intragastric administration was equal to 222.7 times of the clinical routine, with no marked toxic reaction. In the subacute toxicity test, the general condition, blood test, organ humid weight index and histological changes of live and kidney in different dosage groups were similar to the control group. While in the function index of live and kidney, uric acid was stepped down in the middle and large dose groups, and total bilirubin was decreased in the large dose group. The nasal membrane local toxicity test revealed that there was little change in the ultra microstructure of rat nasal membrane.Conclusion The Magnolia biondii Pamp volatile oil nanometer bangosome may have little toxicity by intragastric administration and nose dropping.
