COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Liver transplant patients require lifelong immunotherapy， and if they are infected by SARS-Cov-2， their immune function will face double whammy. This report described the integrated approach of traditional Chinese and western medicine in the treatment of a liver transplant patient with severe COVID-19. The treatment was involved with western medicine such as antiviral， immunosuppressive， focusing on maintaining immune balance. Traditional Chinese medicine was given based on the differentiation of syndromes， targeting at the core pathogenesis and using methods such as promoting qi circulation， clearing heat and resolving dampness， draining lung and relieving panting. Following the treatment， the patient exhibited notable improvement in clinical symptoms and liver function， leading to the effective cessation of disease progression and a shortened recovery period.

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.

Objective To investigate the preventive effect of schisandrin(SCH)on fetal neural tube defects(NTDs)of mice and its mechanism.Methods C57BL/6 mice were mated with female and male at a ratio of 2:1.Pregnant female mice with vaginal plug after mating were randomly divided into control group,model group,SCH group,and folic acid group,with 9 mice in each group.The NTDs fetal mice model was induced by intraperitoneal injection of all-trans retinoic acid(atRA)(7.5 mg/kg)on embryonic day 7.5(E 7.5 d).During E 0.5 d-E 11.5 d,pregnant rats in folic acid group were given folic acid[61.0 μg/(kg·d)]by gavage once a day,and pregnant rats in SCH group were given SCH[8.0 mg/(kg·d)]by gavage once a day.Fetal mice were removed by cesarean section on E 11.5 d.PC12 cells were divided into control group,model group and SCH group.PC12 cells were treated with atRA(20 μmol/L)for 12 hours to establish cell damage model in model group,and treated with SCH(2.5 μmol/L)for 24 hours in SCH group.Fetuses were identified NTDs by stereoscopic microscopy.HE staining was used to observe the closure of the neural tube.The expression levels of p-PI3K,Akt and p-Akt molecules in PI3K/Akt signaling pathway were detected by Western Blotting.Results Compared with control group,the incidence of NTDs was significantly increased in mice of model group(P<0.01);compared with model group,the incidence of NTDs was decreased in folic acid group and SCH group(P<0.01);compared with folic acid group,SCH group had a lower incidence of NTDs(P<0.01).Western Blotting results showed that compared with control group,the expression of p-PI3K and p-Akt protein in fetal tissues of model group was significantly decreased(P<0.01,P<0.05);compared with model group,there was no significant difference in expression of p-PI3K and p-Akt in fetal tissues of folic acid group(P>0.05),while the expression of p-PI3K and p-Akt protein in SCH group was significantly higher(P<0.05).Compared with control group,PC12 cells in model group showed lower expression levels of p-PI3K and p-Akt(P<0.05);compared with model group,PC12 cells in SCH group showed higher expression levels of p-PI3K and p-Akt(P<0.05).Conclusions SCH can reduce the incidence of atRA-induced NTDs in fetal mice,and its preventive effect is better than folic acid,which may be related to the activation of the PI3K/Akt signaling pathway.

OBJECTIVES: To study the clinical efficacy of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain. METHODS: A retrospective analysis was performed on the medical data of 30 children with the chief complaint of chronic abdominal pain who were admitted from August 2019 to May 2021. All the children were found to have inflammation of the appendix or intracavitary stool and fecalith by ultrasound and underwent ultrasound-guided endoscopic retrograde appendicitis therapy. The medical data for analysis included clinical manifestations, endoscopic findings, white blood cell count, neutrophil percentage, length of hospital stay, and cure rate. RESULTS: Among the 30 children with chronic abdominal pain, there were 13 boys (43%) and 17 girls (57%), with a mean age of (9±3) years (range 3-15 years) at diagnosis. The median duration of the disease was 12 months, and the median length of hospital stay was 3 days. The children had a median white blood cell count of 6.7×10⁹/L and a neutrophil percentage of 50%±13%. Fecalith and a large amount of feces were flushed out of the appendix cavity for 21 children (70%) during surgery. The follow-up rate was 97% (29/30), and the median follow-up time was 11 months (range 5-26 months). Of the 29 children, abdominal pain completely disappeared in 27 children (93%). CONCLUSIONS Ultrasound-guided endoscopic retrograde appendicitis therapy is effective in children with chronic abdominal pain caused by feces or fecalith in the appendix cavity.

Objective:To explore the abnormal brain metabolic pattern and connectivity in temporal lobe epilepsy (TLE) patients.Methods:18F-FDG PET images of 75 patients diagnosed as drug resistant unilateral TLE from January 2014 to December 2016 in Huashan Hospital of Fudan University were collected retrospectively, including 41 (22 males, 19 females, age (28.4±8.7) years) left TLE (LTLE) and 34 (13 males, 21 females, age (28.5±8.8) years) right TLE (RTLE). Forty-four healthy controls (24 males, 20 females, age (31.2±6.2) years) were also enrolled. The cerebral glucose metabolism in TLE patients and the controls were analyzed with statistical parametric mapping (SPM) 12. The brain connectivity based on glucose metabolism were analyzed with bilateral hippocampus and amygdala as seeds. Permutation test with 1 000 permutations was used to analyze data. Results:Compared to control group, in both LTLE and RTLE groups, hypometabolism was found in affected hippocampus, amygdala, insula and temporal gyrus and hypermetabolism was observed in health hippocampus, parahippocampal gyrus, amygdala, lenticular nucleus and thalamus. In addition, hypometabolism was also found in affected superior/middle frontal gyrus and hypermetabolism was also found in bilateral frontal-orbital gyrus, bilateral cerebellum, affected lenticular nucleus and thalamus in LTLE group. In both TLE groups, affected seeds exhibited increased connectivity with affected superior frontal gyrus, lingual gyrus, fusiform gyrus, superior/middle temporal gyrus and temporal pole (all P<0.05); affected seeds exhibited increased connectivity with health superior frontal gyrus ( P=0.005), lingual gyrus ( P=0.018) and transverse temporal gyrus ( P=0.016) in RTLE group in addition. Besides, affected seeds exhibited decreased connectivity with bilateral default mode network (DMN) (all P<0.05), affected caudate nucleus ( P=0.015) and health thalamus ( P=0.008), in a uniform distribution pattern in LTLE group, and with bilateral cerebral cortex in an irregular distribution pattern in RTLE group (all P<0.05). In LTLE group, health seeds exhibited more increased connections with superior ( P=0.005)/middle frontal gyrus ( P=0.042), health hippocampus ( P=0.038), parahippocampal gyrus ( P=0.019), amygdala ( P=0.038), posterior cingulate gyrus ( P=0.004), and bilateral fusiform gyrusand ( P=0.048) compared with RTLE group; while, in RTLE group, health seeds exhibited more decreased connections with health superior ( P=0.047), inferior frontal gyrus ( P<0.001), orbital frontal gyrus ( P<0.001) and rectus gyrus ( P=0.016) compared with LTLE group. Conclusion:Altered brain glucose metabolism and connectivity pattern are found and will elucidate the underlying metabolic pattern of TLE.

Work-related musculoskeletal disorders (WMSDs) refer to musculoskeletal disorders caused by work or work as the main cause, which are characterized by high prevalence and heavy burden of disease as a global problem. The classification and catalog of occupational diseases is of great significance for guiding the prevention and control of occupational diseases and safeguarding the rights and interests of workers. The types of WMSDs included in the list of occupational diseases vary greatly from country to country, and the regulations on specific pathogenic factors are also inconsistent. By sorting out and analyzing the lists and characteristics of WMSDs at home and abroad, and using the International Statistical Classification of Diseases and Related Health Problems (ICD-10) in occupational health to standardize of WMSDs in various countries, which would lay the foundation for future multi-country WMSDs occupational health registration and disease burden research, and provide a reference for China to revise the WMSDs list.

With the aging process of population in the society, the prevalence of cardiovascular diseases (CVD) in China is increasing continuously and the number of dental patients with CVD is increasing gradually too. Due to the lack of guidelines for dental patients with CVD in our country, how to implement standardized preoperative evaluation and perioperative risk prevention remains a problem to be solved for dentists at present. The present expert consensus was reached by combining the clinical experiences of the expert group of the Fifth General Dentistry Special Committee, Chinese Stomatological Association and respiratory and cardiology experts in diagnosis and treatment for CVD patients, and by systematically summarizing the relevant international guidelines and literature regarding the relationship between CVD and oral diseases and the diagnosis and treatment of dental patients with heart failure, hypertension and antithrombotic therapy. The consensus aims to provide, for the dental clinicians, the criteria on diagnosis and treatment of CVD in dental patients in China so as to reduce the risk and complications, and finally to improve the treatment levels of dental patients with CVD in China.
