Objective:To summarize the clinical features and postoperative efficacy of patients with oval window atresia accompanied by facial nerve aberration.Methods:The clinical data of patients with congenital middle ear malformation with facial nerve aberration admitted to our hospital from January 2015 to March 2023 were retrospectively analyzed. There were 97 cases (133 ears) in total. Among them, 39 patients (44 ears) had complete follow-up data, including 27 male patients and 12 females, aged 7-48 years old, with an average age of 17.8 years old. Of these, 14 cases (16 ears) were patients combined with facial nerve aberration, and 25 cases (28 ears) were without facial nerve aberration. The results of imaging examination, pure-tone audiometry, selection of surgical strategy, intraoperative findings and postoperative hearing improvement were summarized and analyzed. The malformations of malleus, incus, stapes, oval window and facial nerve were recorded. Prism 9 software was used to statistically analyze the mean bone conductance and air-bone gap of patients before and after surgery.Results:All the 14 patients (16 ears) with middle ear malformation accompanied by facial nerve aberration and oval window atresia showed poor hearing and no facial palsy since childhood. High resolution CT (HRCT) examination of temporal bone, pure tone audiometry and Gelle test were performed before surgery. The malformations of malleus, incus, stapes, oval window and facial nerve were recorded. Preoperative high-resolution CT (HRCT) examination of temporal bone found 12 ears with 4 or more deformities, accounting for 75.00%, in the group of patients with facial nerve malformation. The preoperative average bone conductive threshold was (15.3±10.4) dB and the average air-bone gap was (46.3±10.6) dB in pure-tone audiometry (0.5, 1, 2, 4kHz). According to the different degrees of facial nerve and ossicle malformation, we performed three different hearing reconstruction strategies for the 14 patients (16 ears) with facial nerve aberration and oval window atresia, including 7 ears of incus bypass artificial stape implantation, 7 ears of Malleostapedotomy (MS) and 2 ears of Malleus-cochlear-prothesis (MCP). After 3 months to 18 months of follow-up, all patients showed no facial paralysis. The postoperative mean bone conductive threshold was (15.7±7.9) dB and air-bone gap was (19.8±8.5) dB. There were significant differences in mean air-bone gap before and after operation ( t=7.766, P<0.05), and there was no significant difference between the mean bone conductive threshold before and after surgery ( t=0.225, P=0.824). There was no significant difference of mean reduction of air-bone gap between patients with and without facial nerve aberration ( t=1.412, P=0.165). There was no significant difference between the three hearing reconstruction strategies. There was no significant displacement of the Piston examined by U-HRCT. Conclusion:For patients of middle ear malformation whose facial nerve cover the oval window partially, incus bypass artificial stape implantation or Malleostapedotomy (MS) can be selected according to the specific condition of auditory ossis malformation, and for patients whose facial nerve completely covers the oval window area, Malleus-cochlear-prothesis (MCP) can be selected. Three types of stapes surgery are safe and reliable for patients with oval window atresia accompanied by facial nerve aberration. There was no significant difference in efficacy between them. Preoperative HRCT assessment of middle ear malformation is effective. There is no significant difference of surgical effect with or without facial nerve aberration. The U-HRCT can be used to evaluate the middle ear malformation before surgery and the Piston implantation status after surgery. Due to the risks of surgery, those who do not want to undergo surgery can choose artificial hearing AIDS, such as hearing aid, vibrating soundbridge, bone bridge or bone-anchored hearing aid.

Objective:To analyze the clinical characteristics of necrotizing otitis externa(NOE) and to discuss its clinical staging and treatment.Methods:A retrospective case series study was conducted in the Otorhinolaryngology Head and Neck Surgery Center of Beijing Friendship Hospital. Patients hospitalized in our department with diagnosis of NOE between June 2015 to December 2021 were included. There were 23 patients (23 affected ears), with 19 males and 4 females, aged 32-85 years (the median age was 68 years old). We analyzed and summarized the main symptoms and signs, laboratory examinations, imaging examinations, treatments and prognosis of the patients, and established a database for data collection and sorting.Results:All the 23 patients had various complications. There were 19 cases of type 2 diabetes, 5 cases of anemia, 3 cases of hypoalbuminemia, 2 cases of chronic renal insufficiency, and 1 case of uremia. The main symptoms on admission were otalgia, otorrhea, hearing loss, angular deviation, limited mouth opening, dysphagia and hoarseness. Physical examination showed swelling of the external ear canal (EEC), granulation tissue of the EEC, thin purulent secretion of the EEC, facial paralysis, restricted mouth opening, and decreased vocal cord movement. Etiological results showed 15 cases of Pseudomonas aeruginosa, 5 cases of Staphylococci and 3 cases of Aspergillus fumigatus. Imaging mainly showed abnormal soft tissue shadows of the EEC and middle ear, and temporomandibular joint, parapharyngeal space, skull base, intracranial and other adjacent structures were involved according to the different invasion directions of the lesions. According to the characteristics of these patients, we summarized a diagnostic criteria and clinical staging. All patients received systematic anti-infection, surgery and symptomatic support treatment. Until January 30, 2022, 4 patients died, including 1 case of extensive intracranial infection caused by NOE, and 3 cases of other systemic diseases after the affected ears were recovered and discharged from hospital. The other 19 patients′ ears were cured, the symptoms of otalgia and otorrhea disappeared, and the epithelization of the surgical cavity was good. Conclusion:The clinical manifestations of NOE lack specificity, and the diagnosis should be made according to the medical history, physical examination and auxiliary examination. According to different clinical stages, corresponding treatment measures should be formulated. The treatment is based on multidisciplinary comprehensive treatment, mainly surgical treatment. Early intervention has a good prognosis, otherwise, multiple-group of cranial nerve injury or intracranial infection implies poor prognosis.

Objective:To explore the relationship between the maternal dietary patterns during pregnancy and the early childhood BMI change trajectory.Methods:The subjects were 1 241 pairs of pregnant women and their children in Ma'anshan maternal and infant health cohort. The food frequency questionnaire was used to collect the maternal diet data during pregnancy. The cohort children were followed up at birth, month 3, 6, 12, 18 and 24, respectively. The body height and weight data of the cohort children were collected. The principal component analysis was used to determine the categories of maternal dietary patterns during pregnancy, group-based multi-trajectory modeling was used to fit the early childhood BMI change trajectory, and the multiple classification logistic regression model was used to evaluate the relationship between the maternal dietary patterns during pregnancy and the early childhood BMI change trajectory.Results:The maternal dietary patterns during pregnancy included protein type, healthy type, vegetarian type, processing type and beverage type, which could explain 50.04% of the total dietary variation. Among them, the protein type, main dietary pattern, could explain 21.34% of the total dietary variation. The early childhood BMI change trajectory was from thinnish stature to average stature, then to mild obesity, accounting for 42.9%, 45.6% and 11.5% respectively. After controlling the potential confounding factors, it was found that there was a statistical correlation between healthy type and beverage type of maternal dietary patterns during pregnancy and early childhood BMI change trajectory ( P<0.05). Comparison of change trajectories between thinnish type and average stature type, children in the low-level group of healthy diet pattern tended to have a thinnish type change trajectory in early life ( OR=1.286, 95% CI: 1.002-1.651). Comparison of change trajectories between mild obesity type and average stature type, children in the high-level group of beverage diet pattern tended to have a mild obesity type change trajectory in early life ( OR=0.565, 95% CI: 0.342-0.935). The other dietary patterns had no statistical correlation with the early childhood BMI change trajectory. Conclusions:Maternal dietary patterns during pregnancy can affect the early childhood BMI change trajectory, and the low-level healthy type diet is an independent risk factor for thinnish type change trajectory, and the high-level beverage type diet is an independent risk factor for the mild obesity type change trajectory.

Breast cancer is globally the most common invasive cancer in women and remains one of the leading causes of cancer-related deaths. Surgery, radiotherapy, chemotherapy, immunotherapy, and endocrine therapy are currently the main treatments for this cancer type. However, some breast cancer patients are prone to drug resistance related to chemotherapy or immunotherapy, resulting in limited treatment efficacy. Consequently, traditional Chinese medicinal materials (TCMMs) as natural products have become an attractive source of novel drugs. In this review, we summarized the current knowledge on the active components of animal-derived TCMMs, including Ophiocordycepssinensis-derived cordycepin, the aqueous and ethanolic extracts of O.sinensis, norcantharidin (NCTD), Chansu, bee venom, deer antlers, Ostreagigas, and scorpion venom, with reference to marked anti-breast cancer effects due to regulating cell cycle arrest, proliferation, apoptosis, metastasis, and drug resistance. In future studies, the underlying mechanisms for the antitumor effects of these components need to be further investigated by utilizing multi-omics technologies. Furthermore, large-scale clinical trials are necessary to validate the efficacy of bioactive constituents alone or in combination with chemotherapeutic drugs for breast cancer treatment.

Objective:To investigate the developmental behavior of early term infants at 6 months and its difference from that of complete full-term infants.Methods:A healthy maternal and infant birth cohort in maanshan city, established in Maanshan Maternal and Child Health Hospital from June 2015 to June 2016. Birth outcomes were copied from the hospital electronic medical record system after delivery. The Chinese Ages and Stages Questionnaires was used to assess developmental behavior. The chi-square test and multivariate unconditional logistic regression model were used to analyze the differences in the behavioral development of early and full term infants.Results:The birth rate of early term infants was 24.74% (500/2 021). The detection rates of communication, gross motor, fine motor, problem solving and individual-social areas in early term infants were 2.1%, 3.2%, 6.1%, 6.3% and 2.7%, respectively. The detection rate of problem-solving area in early term infants was significantly higher than that in the full-term infants (6.3% vs. 3.7%, χ 2=5.42, P<0.05). After controlling for confounding factors, compared with full-term infants, the risk of problem-solving area in early infants was significantly increased ( OR=1.65, 95%CI:1.01-2.70, P<0.05). Conclusion:The risk of behavioral retardation in Early term infants is significantly higher than that in full-term infants, and long-term follow-up and appropriate early development promotion interventions are needed to improve their quality of life.

Objective To understand the physical activity of early stage pregnant women and explore its influential factors. Methods From June 2015 to June 2016, 2122 pregnant women with early pregnancy card in Ma An Shan Maternal and Child Health Hospital were selected and surveyed with a questionnaire. The Physical Activity Questionnaire was used to understand the physical activity of pregnant women in their early pregnancy. Analysis of variance and t-test were used to describe the distribution of energy expenditures of physical activity of pregnant women with different demographic characteristics, and multiple linear regression analysis was used to analyze the factors influencing the energy expenditure of their physical activity. Result The duration of activities of sleep and sitting type was (16.56 ± 3.54) h, accounting for 83.38％of total activity time;the energy consumption value was (17.17±5.59) METs·h;mild physical activity time was (2.62±1.86) h, accounting for total time. 13.19％and the energy consumption value was (6.06±4.43) METs·h;the average time of moderate to severe physical activity was (0.68±0.93) h, accounting for 3.42％of total physical activity time, and the energy consumption value was (3.22±4.58) METs·h. In the univariate analysis, the energy expenditures of physical activity between the different groups (t=-3.551), education level (F=1.347), and occupation type (F=1.485) were different, and the difference was statistically significant (P<0.05). In multiple linear regression analysis, different occupational types and education were the energy expenditure levels of physical activity during early pregnancy. Influencing factors (P<0.05). Conclusion Pregnant women have longer periods of sleep and meditation during the first trimester, and shorter duration of physical activity than mild and above;the energy expenditure of physical activity during the first trimester of pregnancy is affected by the occupational type and educational level of the pregnant woman.

OBJECTIVE: We aimed to compare the characteristics between lentivirus and adenovirus vector mediated gene transfer into cultured spiral ganglion cells (SGCs). METHOD: SGCs from newborn rats were cultured and exposed to lentivirus-GFP and adenovirus-GFP vectors. GFP expression and the cell morphology were evaluated under epi-fluorescence microscope at 3 days and 7 days after exposure. Survival number of SGCs was counted, and the average percentage of SGCs with GFP expression was calculated, and axon length was measured by ImageJ software. RESULT: Cultured SGCs were transfected by either adenovirus or lentivirus vector successfully. The adenovirus vector presented an instant and efficient transfection. However, the expression of GFP went down after 7 days. In lentivirus-GFP group, GFP expression was detected at 7 days after exposure, and the number of cells with GFP expression increased gradually in the following days. Statistical analysis revealed that there were no differences in survival number of SGCs and average axon length among lentivirus-GFP group, adenovirus-GFP group and control group. CONCLUSION Cultured SGCs can be transfected by either lentivirus vector or adenovirus vector safely and efficiently. SGCs are more susceptible to adenovirus vector, but GFP persists for a longer period after the lentivirus-mediated gene transfer.
