OBJECTIVE: To explore the risk factors of the newborns who failed initial hearing screening by analysing the distortion production otoacoustic emission (DPOAE) results of 1021 newborns with potential risk factors of hearing loss. METHOD: All newborns, who were born in obstetrical department and admitted in the neonatal department of the Nanfang Hospital during June 2009 to January 2012 and underwent initial hearing screening, were included in this study. Their clinical data and DPOAE results were analyzed retrospectively in order to identify the risk factors for failure of initial hearing screening in infants; cases who failed the DPOAE test were followed up by telephone interviews. RESULT: (1) One hundred and thirty-seven cases (13.42%) of the 1021 newborns did not pass the hearing screening. 51 cases (5.00%) did not pass the test in both ears. Meanwhile, left ear in 47 cases (4.60%) and right ear in another 39 cases (3.82%) failed the test respectively. (2) Univariate analysis showed that 14 factors had significant influence on the hearing screening results, such as birth weight, small for gestational age, multiple pregnancy, gestational age, delivery mode, oligohydramnion, oxytocin, blood sugar level of newborn, Apgar scores at 1 min, exposed prenatally to glucocorticoid, maxillofacial deformity, hypoxic-ischemic encephalopathy, neonatal respiratory distress syndrome and neonatal asphyxia (P < 0.01). (3) Multivariate Logistic regression analysis suggested that birthweight less than 1500 g, multiple pregnancy, Apgar scores of 0-4 at 1 min, exposed prenatally to glucocorticoid and maxillofacial deformity were risk factors for failure of initial hearing screening (OR were 3.132, 1.808, 2.615, 1.827 and 12.174 respectively; 95% CI were 1.466-6.691, 1.120-2.917, 1.317-5.336, 1.130-2.953 and 1.986-74.632 respectively). (4) Results of telephone interviews revealed that Apgar scores of 0-4 at 1 min would be a risk factor of language development. CONCLUSION Birthweight less than 1500 g, multiple pregnancy, Apgar scores of 0-4 at 1 min, exposed prenatally to glucocorticoid and maxillofacial deformity are risk factors of failure of initial hearing screening among newborns with potential hearing loss. Monitoring of the hearing condition of the infants at risk should be strengthened.

OBJECTIVE: To evaluate the clinical characteristics of tinnitus complaint. METHOD: The information of 628 patients with subjective tinnitus was collected using questionnaires from October, 2013 to June, 2014. Among them, 453 cases were included in this study, whose quality of life and sleep were significantly affected. Then we elucidated the features of tinnitus, tinnitus incentives and systemic diseases and analyzed their relationship. RESULT: The proportion of the patients complaint was highest in gruop ≤ 30 y. The patients with tinnitus complaint were more likely to have persistent tinnitus with higher loudness VAS scores than their counterparts. 65.4% of the total patients had at least one treatment (52.2% of patients can tolerate, and only 13. 2% can not tolerate). More patients had cranial Ming on the left than on the right ear. The proportion of patients with polyphony in bilateral tinnitus was higher than those with unilateral tinnitus (P < 0.05). Moreover, 59% patients had tinnitus inducing factors, and 44% patients had systemic comorbidities (The three most frequently involved systems were otolaryngologic, cardiovascular and digestive system). There was no significantly statistical difference of the tinnitus severity between patients with other systematic diseases and those without. CONCLUSION Patients with tinnitus complaint were younger in age (≤ 30 y) and more likely to have persistent tinnitus with higher loudness VAS scores Predisposing factors are closely associated with mental or physical trauma. The accompanied diseases can be classified by organ system.

The aim of this study was to conduct the preparation and pharmaceutical characterization of a new type of terbinafine hydrochloride bioadhesive film-forming gel. The viscosity of the gel of(13 299±51)mPa ·s, pH of 3. 50±0. 50, and the shearing viscosity of(196±4)g/cm2 was found. This new gel turned out to be a layer of solid film on the application site in a very short time. The remaining solid ratio of the resulting film was estimated to be(50. 74±2. 81)%; the tensile strength was(1. 17±0. 21)MPa; and the breaking elongation was(21. 42±3. 24)%. In vitro release behavior of terbinafine hydrochloride from the film was investigated according to the paddle over disk method in ChP2010. Terbinafine hydrochloride released continuously for 10 h from the film. Improved Franz type diffusion cells were used in vitro transdermal studies by the application of excised minipigs skins. No penetration of drug into the receptor medium across the skin existed and so it could imply the safety for local application. It was found that(93. 05±5. 66)% of drug stayed on the skin surface while(1. 15±0. 85)% entered into the skin, which was beneficial for the treatment of superficial skin fungal infection.

Objective: To investigate the clinicopathological features and prognostic parameters of the inflammatory pseudotumor-like follicular dendritic cell sarcoma (IPT-like FDCS) of liver and spleen. Methods: Ninteen cases of inflammatory pseudotumor (IPT) and 5 cases of IPT-like FDCS of the liver and spleen were collected at the First Affiliated Hospital, Army Medical University from 2006 to 2016. HE sections, immunohistochemical staining, and Epstein-Barr virus encoded nuclear RNA (EBER) in situ hybridization were reviewed along with a summary of the literature. Results: Among the previously diagnosed 19 cases of IPT of the liver and spleen, 2 cases were misdiagnosed (the ratio of 2/19). Among 7 new cases including 3 males and 4 females, 3 cases involved the liver and 4 cases involved the spleen. The age range was 37-64 years (mean 53 years). The maximum tumor diameter ranged from 3.0 to 11.0 cm (mean 6.5 cm). Surgical resections were performed in all patients with follow-up time ranging from 3 to 84 months.All patients were disease-free.7 new cases were all positive for EBER, and showed the expression of at least one of the FDC markers, including CD21, CD23, and CD35. The rest of 17 cases of IPT were all negative for EBER and essentially negative for FDC markers, but were all positive for SMA. Conclusions IPT-like FDCS of the liver and spleen is a rare low-grade malignant tumor morphologically mimicking inflammatory pseudotumor, and is easy to be misdiagnosis due to under-recognition. EBER in situ hybridization and FDC markers are indispensable for confirming the diagnosis.

Under the background of " Internet+ medical treatment" and the continuous deepening of face recognition technology research, the face recognition industry has continued to mature, and face recognition has been initially applied in medical fields such as hospital management, auxiliary medical care, and epidemic prevention and control. At the same time, face recognition technology brings problems including error risk, technical cracking risk, privacy risk, equality risk, abuse risk, and other issues in practice, which seriously threaten the personal and property rights and interests of the public. On the basis of summarizing the specific application direction of face recognition technology in hospitals, the authors sorted out the legal regulation of face recognition in China, and proposed that it should be based on technology research and development, strengthen the " gatekeeper" responsibility of medical institutions, improve legal system and recommendations for strengthening judicial leadership in order to improve the legal regulations of face recognition technology, reduce the risk of infringement by medical institutions in the application of face recognition technology, and protect the legitimate rights and interests of citizens.

In order to explore the role of pre-basic course teaching in the standardized training of residents in clinical pathology, we have independently designed and constructed a pre-basic course teaching system mainly focusing on anatomy and histoembryology, consisting of two levels of theoretical teaching (small lectures by students and systematic lectures by instructors) and two dimensions of practical training (sample collection teaching and case teaching). This teaching model centering on participatory lecturing, practice, summarization, assessment, and feedback has been demonstrated effective. The results showed that the theoretical and practical assessment scores of the experimental group [(458.80±17.60) and (415.40±19.30), respectively] were significantly higher than those of the control group [(444.50±20.90) and (398.80±23.70), respectively]. Among 28 students of grades 2019 to 2021 surveyed for teaching effectiveness, 96.43% were satisfied with the teaching model. The established teaching model provides new ideas for the reform of teaching methods in the standardized training of residents in clinical pathology.
