In audiovisual emotion recognition, representational learning is a research direction receiving considerable attention, and the key lies in constructing effective affective representations with both consistency and variability. However, there are still many challenges to accurately realize affective representations. For this reason, in this paper we proposed a cross-modal audiovisual recognition model based on a multi-head cross-attention mechanism. The model achieved fused feature and modality alignment through a multi-head cross-attention architecture, and adopted a segmented training strategy to cope with the modality missing problem. In addition, a unimodal auxiliary loss task was designed and shared parameters were used in order to preserve the independent information of each modality. Ultimately, the model achieved macro and micro F1 scores of 84.5% and 88.2%, respectively, on the crowdsourced annotated multimodal emotion dataset of actor performances (CREMA-D). The model in this paper can effectively capture intra- and inter-modal feature representations of audio and video modalities, and successfully solves the unity problem of the unimodal and multimodal emotion recognition frameworks, which provides a brand-new solution to the audiovisual emotion recognition.

OBJECTIVE To mine the focus and emotional attitude of the public on rare diseases， and to provide decision- making reference for relevant departments to formulate and implement relevant policies， systems and strategies for medical security of rare diseases. METHODS Latent Dirichlet allocation （LDA） topic model and sentiment analysis method were used to analyze the comment text of short videos related to the “nosinasine” medical insurance admission event on the Bilibili video website， mine the theme and sentiment tendency of the text， and put forward relevant strategy suggestions. RESULTS A total of 8 videos with tens of thousands of playback and 7 109 text data were obtained. According to the LDA analysis， online public paid attention to 9 topics related to rare diseases （the price of rare disease drugs， the inclusion of rare disease drugs in medical insurance， the status quo of research and development of rare disease drugs， the scope of medical insurance and the medical security system， the plight of rare disease patients， the prevention and screening of rare diseases， the value of rare disease drugs in medical insurance， the Chinese and western medical methods of rare diseases， and the supply and demand status of rare disease drugs）， which could be summarized into 4 categories according to the objects of concern （rare disease drugs， rare disease medical insurance， rare disease medical and health services and rare disease patient groups）. On the whole， the emotional tendency of the Internet public towards each topic showed a low positive and high negative tendency. CONCLUSIONS The public paid more attention to the price， research and development， supply and demand of rare disease drugs， and was deeply worried about the current medical status of rare diseases in China. To strengthen and improve the medical security for patients with rare diseases， such as actively carrying out public health services for rare diseases， strengthening cooperation in the diagnosis and treatment of rare diseases， and researching rare disease drugs， etc. Chinese medical and health departments can make concerted efforts in medical and health services， drug supply security， medical security and other social security.

To evaluate the association between serum anti-tissue transglutaminase antibody (anti-tTG) titers and the severity of histological damage to the duodenal mucosa and to predict a possible anti-tTG cutoff value for diagnosing celiac disease (CD) and villous atrophy in the domestic population. Clinical and pathological data from 76 adult CD patients with positive anti-tTG titers and duodenal biopsy results who were treated at the People′s Hospital of Xinjiang Uygur Autonomous Region from July 2017 to January 2022 were retrospectively analyzed. The correlation between anti-tTG titers and the severity of duodenal mucosal damage was statistically assessed to predict the optimal anti-tTG titer cut-off value for diagnosing CD and villous atrophy. Of the 76 patients, 10 had underlying CD, and of the 66 patients with duodenal histopathology, four were Marsh Ⅰ, six were Marsh Ⅱ, and 56 were Marsh Ⅲa-c grade. In adults with CD, anti-tTG titers were shown to be associated with the severity of histological damage to the duodenal mucosa. When the anti-tTG level was ≥5 times the upper limit of normal (ULN), the sensitivity and specificity for diagnosing CD were 83.9% and 92.9%, respectively. When the anti-tTG titer was ≥8 times the ULN, the sensitivity and specificity for diagnosing villous atrophy were 67.9% and 90.0%, respectively. Anti-tTG levels had a strong predictive value for diagnosing CD in adults when titers exceeded 10 times the ULN. Thus, the anti-tTG cut-off value can be combined with clinical judgment to diagnose CD, limiting the use of invasive endoscopy.

ObjectiveTo analyze the online public Q&A texts on HPV vaccine， focus on the important issues related to HPV vaccination and cervical cancer prevention in China， and propose strategies and suggestions. MethodsThe latent Dirichlet allocation （LDA） topic model was employed to extract key topics of 15 565 Q&A texts related to HPV vaccines from the social Q&A platform "Zhihu". The Baidu AI sentiment analysis tool was used to analyze the emotional tendencies of the texts corresponding to each topic， and the topics were classified based on the strategic coordinate method. ResultsOnline users focused on eight topics about HPV vaccine information. Among them， vaccination knowledge， HPV vaccination hesitation， and HPV vaccine development and marketing belonged to the low positivity-high negativity emotional topics， HPV infection and high-risk factors belonged to the low positivity-low negativity emotional topics， and HPV vaccine appointment channels， comparison between domestic and imported vaccines， HPV vaccines and cervical cancer prevention， and HPV vaccine types and selection were grouped under high positivity-low negativity emotional topics. ConclusionPublic concerns regarding HPV vaccines can be classified into three major dimensions： health knowledge， health beliefs， and health behaviors. Overall， the public's views and attitudes towards vaccine-related issues are not optimistic. Strengthening science publicity and education， enhancing vaccine supervision， and encouraging enterprises’ innovative research and development capability are effective strategies to improve public awareness of cervical cancer prevention and accelerate the full HPV vaccination coverage.

Oral squamous cell carcinoma(OSCC),a common malignancy of the head and neck,ranks sixth worldwide in terms of cancers with the most negative impact,owing to tumor relapse rates,cervical lymphnode metastasis,and the lack of an efficacious systemic therapy.Its prognosis is poor,and its mortality rate is high.Octamer-binding transcription factor 4(OCT4)is a member of the Pit-Oct-Unc(POU)family and is a key reprogramming factor that produces a marked effect in preserving the pluripotency and self-renewal state of embryonic stem cells(ESCs).According to recent studies,OCT4 participates in retaining the survival of OSCC cancer stem cells(CSCs),which has far-reaching implications for the occurrence,recurrence,metastasis,and prognosis of oral carcinogenesis.Therefore,we summarize the structure,subtypes,and function of OCT4 as well as its role in the occurrence,progression,and prognosis of OSCC.

Iron is an important trace element in human body. It is involved in heme synthesis, myelin sheath formation, mitochondrial respiratory chain electron transfer, DNA replication, repair，epigenetic control and so on. In order to maintain iron homeostasis, the body maintains iron balance by regulating the absorption of dietary iron by intestinal cells, recovery of iron by macrophages and storage of iron in liver cells. These iron metabolism regulation processes involve sophisticated cellular and molecular regulatory systems. When iron homeostasis is broken, both iron deficiency and iron overload will result in damage to the body. In this review, we review the research progress on the absorption, distribution and recovery of iron, the cellular and molecular regulatory mechanisms of iron metabolism and the consequences of iron homeostasis imbalance.

Objective:To investigate the clinical manifestations and pathological features of adult celiac disease in Xinjiang Uygur Autonomous Region.Methods:From January 2016 to December 2019, the clinical data of 943 patients with gastrointestinal symptoms such as chronic diarrhea, abdominal pain, abdominal distension and visited the People′s Hospital of Xinjiang Uygur Autonomous Region were collected. All patients tested for serum anti-tissue transglutaminase antibody inmunoglobulin A (tTG-IgA). And patients with positive serum tTG-IgA underwent gastroscopy and colonoscopy examination. To observe whether duodenal and ileal mucosal villi atrophy and histopathological examination was performed. Body mass index (BMI), hemoglobin, serum calcium, serum albumin level were compared between patients with and without celiac disease. T test and chi-square test were used for statistical analysis. Results:Serum tTG-IgA was positive in 30 patients, and 28 cases were finally diagnosed as celiac disease. The detection rate of celiac disease of Kazakh patients was higher than that of Uygur and Han patients (17.3%, 9/52 vs. 3.2%, 12/375 and 1.4%, 6/427), the detection rate of celiac disease of Uygur was higher than that of Han, and the differences were statistically significant ( χ2=7.65, 5.42 and 5.98, all P<0.05). The main clinical manifestations of 28 patients with celiac disease were weight loss or marasmus (71.4%, 20/28), iron deficiency anemia (67.9%, 19/28), persistent fatigue (57.1%, 16/28) and chronic diarrhea (53.6%, 15/28). The serum tTG-IgA level of patients with celiac disease was higher than that of patients without celiac disease ((131.97±64.58) CU vs. (7.58±1.92) CU), while the levels of BMI, hemoglobin, serum calcium and serum albumin were all lower than those of patients without celiac disease ((15.4±2.9) kg/m 2 vs. (23.8±3.4) kg/m 2, (110±28) g/L vs. (138±12) g/L, (1.70±0.20) mmol/L vs. (2.52±0.15) mmol/L, and (31.5±11.6) g/L vs. (48.2±7.3) g/L, respectively), and the differences were statistically significant ( t=2.473, 2.521, 2.641, 2.734 and 2.512, all P<0.05). Under gastroscopy all patients with celiac disease had atrophy of duodenal mucosal villi, which mainly appeared as nodular mucosal atrophy, grooves and fissure like changes, and villous atrophy was confirmed by histopathology. Conclusions:The detection rates of celiac disease in Kazakh and Uyghur in Xinjiang Uygur Antonomous Region are significantly higher than that of Han nationality. Celiac disease screening has a certain clinical significance.

Objective To observe the clinical effects of different fluid therapies in treating severe preeclampsia complicated by ascites. Methods Between Jan. 2010 and Dec. 2012, patients with severe preeclampsia complicated by ascites in Shenzhen Maternity and Child Healthcare Hospital were included in this study. The treatment group ( n=55 ) were given intravenous drip of 6% hydroxyl starch 130/0. 4 plus furosemide, and the control group (n=52) received intravenous drip of 5%human serum albumin plus furosemide. The mean arterial pressure, respiratory rate, heart rate, oxyhemoglobin saturation, colloid osmotic pressure, hematocrit and the incidence of acute pulmonary edema were observed and compared between the two groups. Results Twenty-four hours after cesarean section, the mean arterial pressure of the treatment group was significantly lower than that of the control group, whereas heart rate and oxyhemoglobin saturation were significantly higher (all P<0. 05). The incidence of acute pulmonary edema of the control group was 17. 3%, while no patient in the treatment group developed acute pulmonary edema. On the 5th day after surgery, the hematocrit and 24 h proteinuria were significantly lower in the treatment group, while colloid osmotic pressure was higher (all P<0. 05). There was no difference in serum albumin level between the two groups (P>0. 05). The average duration of edema after treatment was significantly shorter in the treatment group [(2. 43±0. 37) d versus (3. 74±0. 59) d, P<0. 01]. Conclusion 6% hydroxyl starch 130/4. 0 plus furosemide can effectively elevate the colloid osmotic pressure, resolve edema, improve hypovolemia, sustain oxygen supply to the organs and decrease the complication of pulmonary edema in patients with severe preeclampsia complicated by ascites.
