Olfactory disorders are a common symptom in patients with chronic rhinosinusitis, and their diagnosis and treatment have garnered extensive attention from both patients and doctors. Currently, there are various evaluation and treatment methods for olfactory dysfunction; however, choosing a simpler and more accurate assessment, as well as an effective treatment, remains a clinical challenge. In this article, we review the assessment and treatment methods commonly used in clinical practice in recent years to provide better support for the diagnosis and treatment of olfactory disorders.

Persistent and maladaptive drug-related memories represent a key component in drug addiction. Converging evidence from both preclinical and clinical studies has demonstrated the potential efficacy of the memory reconsolidation updating procedure (MRUP), a non-pharmacological strategy intertwining two distinct memory processes: reconsolidation and extinction-alternatively termed "the memory retrieval-extinction procedure". This procedure presents a promising approach to attenuate, if not erase, entrenched drug memories and prevent relapse. The present review delineates the applications, molecular underpinnings, and operational boundaries of MRUP in the context of various forms of substance dependence. Furthermore, we critically examine the methodological limitations of MRUP, postulating potential refinement to optimize its therapeutic efficacy. In addition, we also look at the potential integration of MRUP and neurostimulation treatments in the domain of substance addiction. Overall, existing studies underscore the significant potential of MRUP, suggesting that interventions predicated on it could herald a promising avenue to enhance clinical outcomes in substance addiction therapy.

Repetitive transcranial magnetic stimulation (rTMS) is a rapid and effective therapy for major depressive disorder; however, there is significant variability in therapeutic outcomes both within and across individuals, with approximately 50% of patients showing no response to rTMS treatment. Many studies have personalized the stimulation parameters of rTMS (e.g., location and intensity of stimulation) according to the anatomical and functional structure of the brain. In addition to these parameters, the internal states of the individual, such as circadian rhythm, behavior/cognition, neural oscillation, and neuroplasticity, also contribute to the variation in rTMS effects. In this review, we summarize the current literature on the interaction between rTMS and internal states. We propose two possible methods, multimodal treatment, and adaptive closed-loop treatment, to integrate patients' internal states to achieve better rTMS treatment for depression.

OBJECTIVE To determine the incidence and prognosis of olfactory,gustatory and auditory dysfunctions related to the COVID-19 Omicron strain infection.METHODS A cross-sectional investigation was performed through online questionnaires.Data of patients with Omicron strain infection from December 24th,2022 to January 2nd,2023 were collected.The visual analogue scale(VAS)was used to evaluate the self-reported olfactory,gustatory and auditory functions of patients.RESULTS A total of 869 valid questionnaires were obtained.The incidence of otolaryngology-related symptoms associated with omicron strain infection was 96.8%.The incidence of olfactory,gustatory and auditory dysfunction was 44.4%,44.2%and 10.7%,respectively.There were statistically significant differences(P<0.001)in VAS scores for olfactory,gustatory,and auditory impairments between all surveyed individuals before and after infection,as well as in the corresponding VAS scores for those who experienced these impairments.The median duration of olfactory,gustatory and auditory dysfunction were 5,4 and 3 days,respectively.CONCLUSION The incidence of olfactory,gustatory,and auditory impairments is high after Omicron infection,with most cases experiencing rapid spontaneous improvement.For the long-term symptoms,the otolaryngology doctors are responsible for exploring and developing effective intervention measures.

Objective To compare the immediate effects of acupuncture at the true and false acupoints of Yanglingquan on functional connectivity in sensorimotor network(SMN)and dorsal attentional network(DAN)of stroke patients based on functional magnetic resonance imaging(fMRI)technology;To explore the central regulatory mechanism and acupoint specificity of acupuncture in stroke patients with hemiplegia.Methods Totally 20 patients with stroke and hemiplegia were included in the study.fMRI scans of acupuncture at the true and false acupoints of Yanglingquan were performed once every 2 weeks,and motion-related SMN and DAN were extracted by independent component analysis to compare the differences in functional connectivity.Results In SMN,after acupuncture at the Yanglingquan true acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior central gyrus,superior temporal gyrus,inferior frontal gyrus,cuneiform lobe,and anterior cuneiform lobe,as well as the left middle temporal gyrus,occipital gyrus,superior temporal gyrus,parahippocampal gyrus,inferior frontal gyrus,and superior temporal gyrus.After acupuncture at the Yanglingquan false acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior central gyrus,superior frontal gyrus,middle frontal gyrus,and cingulate gyrus,as well as the left medial frontal gyrus,anterior cingulate gyrus,lentiform nucleus,and caudate nucleus.In DAN,after acupuncture at the Yanglingquan true acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior cingulate lobe,superior temporal gyrus,middle temporal gyrus,and occipital gyrus,as well as the left cingulate gyrus,posterior cingulate gyrus,and anterior cingulate lobe.After acupuncture at the Yanglingquan false acupoint,the functional connectivity was enhanced compared with before acupuncture,and the enhanced brain areas included the right anterior cingulate gyrus,left anterior cingulate gyrus,and medial frontal gyrus.Conclusion Acupuncture at Yanglingquan can activate SMN and DAN bilateral related brain regions in patients with hemiplegia,which may promote the recovery of motor function by regulating the initiation and execution of motor activities,and has more acupoint specificity compared with false acupoint.

Objective:To explore the clinical characteristics and genetics of a Chinese patient with Gitelman syndrome (GS) and improve the awareness and diagnosis of GS among clinicians.Methods:Retrospectively analyzed the GS patient's clinical feature, laboratory examination, diagnosis, treatment and literature review admitted to Hebei General Hospital in September 2022.Results:A twelve-year-old boy was admitted to our department due to weakness of lower limbs. Laboratory tests after admission showed hypokalemia, hypomagnesemia, hypocalcemia and metabolic alkalosis. Genetic testing showed tow compound heterozygous mutations in the SLC12A3 gene (c.1456G>A and c.634G>A), which ultimately diagnosed as GS. The patient is on the mend and allowed to leave the hospital after treated by potassium supplement.Conclusion:The rate of leak diagnosis is high. Genetic testing should be undergo earlier if the patients suspected GS.

Objective:To explore the influencing factors of pregnant women's fear of childbirth.Methods:From January 2020 to February 2021, convenience sampling was used to select pregnant women attending the Department of Gynecology and Obstetrics of Nanjing Integrated Traditional Chinese and Western Medicine Hospital as the research object. The General Information Questionnaire, Edinburgh Postnatal Depression Scale (EPDS) , the Chinese Version of Wijma Delivery Expectancy/Experience Questionnaire Version A (W-DEQ-A) were used for investigation. Binomial Logistic regression was used to analyze the influencing factors of pregnant women's fear of childbirth. A total of 385 questionnaires were distributed and 359 valid questionnaires were returned.Results:According to the degree of fear of childbirth, 359 pregnant women were divided into mild to moderate fear group ( n=293) and severe fear group ( n=66) . The frequency of pregnancy, infertility treatment, planning pregnancy, whether it is consistent with the expected delivery method, and depression were the influencing factors of pregnant women's fear of childbirth ( P<0.05) . Conclusions:We should focus on pregnant women's fear of childbirth, and carry out interventions for influencing factors.

Objective:To investigate the effects of different chemotherapy dose intensity on the short-term efficacy and adverse reactions of patients with advanced colon cancer.Methods:A real-world database of patients with advanced colon cancer in Wangjing Hospital of China Academy of Chinese Medical Sciences and China-Japan Friendship Hospital from January 2017 to December 2020 was established, including 105 patients treated with the same chemotherapy regimen for two consecutive cycles. The patients were grouped according to the average relative dose intensity (ARDI) of chemotherapy, and the population differences, treatment regimens, short-term efficacy and adverse reactions of different chemotherapy dose intensities were evaluated. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of ARDI for short-term efficacy.Results:There were 31 patients in the high dose intensity group (ARDI≥80%) , 34 patients in the medium dose intensity group (80%0.05) . ROC curve analysis found that the area under the curve predicting objective response was 0.70, the sensitivity was 92.30%, and the specificity was 52.10% when the chemotherapy ARDI threshold was 64%. Conclusion:In the real world, colon cancer patients receiving high dose intensive chemotherapy have better objective response rate, and tumor markers decreased significantly. The baseline status of colon cancer patients receiving low dose intensive chemotherapy is poor, but there is no statistically significant difference in disease control rate between patients receiving low dose intensive chemotherapy and patients receiving high dose intensive chemotherapy, and the adverse reactions are controllable.

[Abstract] Objective: To explore the key genes and molecular mechanisms of liver metastasis in colorectal cancer (CRC), and to provide potential targets and biomarkers for the treatment of CRC with liver metastasis. Methods: Based on the bioinformatics method, the gene data sets of CRC liver metastasis were downloaded from the GEO database to screen the differentially expressed genes (DEGs); the GO and KEGG enrichment analyses of DEGs were performed by using DAVID online tool, and the protein-protein interaction (PPI) network was constructed to screen out the key genes, and subsequently the prognosis was analyzed. Results: A total of 321 DEGs were selected from 183 CRC specimens and 39 liver metastasis specimens, including 153 up-regulated genes and 168 downregulated genes. The results of enrichment analysis of GO and KEGG showed that the functions of DEGs were mainly related to protein activation cascade, inflammatory response, extracellular matrix, platelet degranulation, complement and coagulation cascade reaction etc. 8 key CRC genes (ALB, APOB, FGA, F2, APOA1, SERPINC1, FGG and AHSG) were screened by PPI network. Survival analysis showed that patients with high expressions of SERPINC1 and FGG had poor prognosis(all P<0.05). Conclusion: The biological functions and signaling pathways of DEGs are related to the occurrence and development of liver metastasis. The 8 key genes may be the potential therapeutic targets of CRC liver metastasis, and SERPINC1 and FGG may be new prognostic markers.

Objective:To investigate and evaluate the anti-tumor activity of hydroxychloroquine ( HCQ) in vitro. Methods:CCK-8 assay was applied to detect the inhibitory effect of HCQ at different concentrations(4. 78, 9. 55, 19. 10, 38. 20,76. 40 μg?ml-1 ) on A549 cells, HepG2 cells, HT-29 cells, K562 cells, Hela cells and B16 cells. Absorbance was detected by a microplate reader, and then the inhibitory rate of the tumor cells and the IC50 was calculated. Results:Compared with those of the negative control group, the inhibitory rates of HCQ at different concentrations against the six tumor cells were all increased significantly in a dose-dependent manner (P<0. 01). The inhibitory rates of the tumor cells were all above 60% when the concentration reached 38. 20μg?ml-1. The IC50 was 26. 70(A549), 27. 47(HepG2), 5. 72(HT-29), 14. 03(K562), 20. 21(Hela) and 13. 62(B16) μg?ml-1, respectively. Conclusion:HCQ shows anti-tumor activity on several cancer cells in vitro. There may be a good application prospect for HCQ in the treatment of colorectal cancer, liver cancer, cervical cancer, melanoma and leukemia.
