Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

The diagnosis and treatment of the patient reveals the importance of multidisciplinary team on the diagnosis and treatment of rare and difficult diseases.

Objective: To analyze the current adherence to imatinib in patients with gastrointestinal stromal tumors (GIST) in China and its influencing factors. Methods: A cross-sectional survey was conducted. Study period: from October 1, 2020 to November 31, 2020. Study subjects: GIST patients taking imatinib who were diagnosed and treated in public tertiary level A general hospitals or oncology hospitals; those who had not been pathologically diagnosed, those who never received imatinib, or those who had taken imatinib in the past but stopped afterwards were excluded. The Questionnaire Star online surgery platform was used to design a questionnaire about the adherence to adjuvant imatinib therapy of Chinese GIST patients. The link of questionnaire was sent through WeChat. The questionnaire contained basic information of patients, medication status and Morisky Medication Adherence Scale. Results: A total of 2162 questionnaires from 31 provinces, autonomous regions, and municipalities were collected, of which 2005 were valid questionnaires, with an effective rate of 92.7%. The survey subjects included 1104 males and 901 females, with a median age of 56 (22-91) years old. Working status: 609 cases (30.4%) in the work unit, 729 cases (36.4%) of retirement, 667 cases of flexible employment or unemployment (33.3%). Education level: 477 cases (23.8%) with bachelor degree or above, 658 cases (32.8%) of high school, 782 cases (39.0%) of elementary or junior high school, 88 cases (4.4%) without education. Marital status: 1789 cases (89.2%) were married, 179 cases (8.9%) divorced or widowed, 37 cases (1.8%) unmarried. Two hundred and ninety-four patients (14.7%) had metastasis when they were first diagnosed, including 203 liver metastases, 52 peritoneal metastases, and 39 other metastases. One thousand eight hundred and sixty-nine patients underwent surgical treatment, of whom 1642 (81.9%) achieved complete resection. The median time of taking imatinib was 25 (1-200) months. Common adverse reactions of imatinib included 1701 cases (84.8%) of periorbital edema, 1031 cases (51.4%) of leukopenia, 948 cases (47.3%) of fatigue, 781 cases (39.0%) of nausea and vomiting, 709 cases (35.4%) of rash, and 670 cases (33.4%) of lower extremity edema. The score of the Morisky Medication Adherence Scale showed that 392 cases (19.6%) had poor adherence, 1023 cases (51.0%) had moderate adherence, and 590 cases (29.4%) had good adherence. Univariate analysis showed that gender, age, work status, economic income, residence, education level, marriage, the duration of taking medication and adverse reactions were associated with adherence to adjuvant imatinib therapy (all P<0.05). Multivariate analysis showed that female (OR=1.264, P=0.009), non-retirement (OR=1.454, P=0.001), monthly income ≤4000 yuan (OR=1.280, P=0.036), township residents (OR=1.332, P=0.005), unmarried or divorced or widowed (OR=1.362, P=0.026), the duration of imatinib medication >36 months (OR=1.478, P<0.001) and adverse reactions (OR=1.719, P=0.048) were independent risk factors for poor adherence to adjuvant imatinib. Among patients undergoing complete resection, 324 (19.7%) had poor adherence, 836 (50.9%) had moderate adherence, and 482 (29.4%) had good adherence. Meanwhile, 55 patients with good adherence (11.4%) developed recurrence after surgery, 121 patients with moderate adherence (14.5%) developed recurrence, 61 patients with poor adherence (18.8%) developed recurrence, and the difference was statistically significant (P=0.017). Conclusions: The adherence to adjuvant therapy with imatinib in Chinese GIST patients is relatively poor. Females, non-retirement, monthly income ≤4000 yuan, township residents, unmarried or divorced or widowed, the duration of imatinib medication >36 months, and adverse reactions are independently associated with poor adherence of GIST patients. Those with poor adherence have a higher risk of recurrence after surgery. Positive interventions based on the above risk factors are advocated to improve the prognosis of patients with GIST.

ObjectiveTo analyze the clinical data of CT perfusion imaging （CTP） before and after treatment in acute ischemia stroke （AIS） patients， and to identify the imaging and clinical features related to prognosis. MethodsA total of 39 CT/MRI confirmed AIS patients （Male： Female = 21：18， mean age： 65 years， mean onset time： 8.4 h） were prospectively included， and they were followed for 90 days to obtain their mRS score （mean 2.8）. All patients underwent 320-row spiral CTP scan， and non-contrast CT （NCCT）， CT angiography （CTA） and CT perfusion （CTP） were generated. ASPECTS score and CTP perfusion parameters （CBF， CBV， MTT， TTP， Delay-TTP） were calculated. In addition， the volume of cerebral ischemia core， ischemic penumbra and their ratio were obtained. Three ROIs with similar size were placed in the cerebral infarction core， ischemic penumbra and corresponding contralateral brain parenchyma， and all the parameters were measured three times respectively， to take the average value. ResultsOf 39 AIS patients， 20 patients showed good prognosis （mRS≤2）. Correlation analysis showed that NIHSS score， ischemia core volume， MTT and delayed-TTP in ischemic penumbra were significantly positively correlated with mRS scores at 90 days （P≤0.04）， while the post-treatment ASPECTS and CBF in the ischemia core were significantly negatively correlated with mRS scores at 90 days （P< 0.05）. Further comparative analysis demonstrated that NIHSS score before and after treatment， ASPECTS after treatment and ischemia core volume and CBF in ischemia core were significantly different in AIS patients with good or bad prognosis （P≤0.03）. ROC analysis showed that NIHSS score had the highest diagnostic value in predicting the prognosis of AIS patients （AUC： 0.90）， and the sensitivity， specificity and cut-off values were 79%， 85% and 4.5， respectively. CBF in the ischemia core had the best specificity （89%） and the post-treatment ASPECTS demonstrated the highest sensitivity （94%） in prognosis predicting of AIS patients. ConclusionsIschemia core volume， CBF， NIHSS score before and after treatment， and post-treatment ASPECTS of AIS patients are closely related with their prognosis. Compared with NIHSS score， the ischemia core CBF has a higher specificity in predicting the prognosis of AIS patients.

【Objective】To investigate the impact of long- term storage time on epigenetic modification of histone in human cleavage stage embryos.【Methods】According to the length of storage time，donated embryos after slow-freezing were divided into 3 groups ：6-year group ，9-year group ，and 12-year group ，while the control group consisted of donated fresh embryos. Immunocytochemistry was performed to compare the expression levels of HDAC1， H3K9ac， H3K4me3 ，and H3K9me3 among 4 groups. Transcription levels of HDAC1 ，SUV39H1 ，SETDB1 ，and KDM5A were analyzed through Single-Cell qRT-PCR.【Results】The relative abundances of HDAC1 and SUV39H1 mRNA showed no significant differences among 4 groups（P > 0.05）. SETDB1 exhibited a climbing pattern as storage time increased，but no significant difference was observed（P > 0.05）. There were no differences in H3K9 trimethylation and H3K9 methylation among 4 groups. However ，the expression level of KDM5A increased with the increasing storage time（P < 0.05）.【Conclusions】 Storage time did not affect the expression of deacetylase HDAC1，methylase SUV39H1 and SETDB1. H3K9ac/me3 and H3K4me3 also exhibited no significant difference as the storage time increases. However ，the increasing storage length might induce the elevating expression of demethylase KDM5A，which may be associated with inhibition of embryonic transcription.
