ObjectiveTo observe the clinical effectiveness and safety of Xiaozhong Zhitong Mixture （消肿止痛合剂） combined with antibiotic bone cement in the treatment of diabetic foot ulcer （DFU） with damp-heat obstructing syndrome. MethodsA total of 72 DFU patients with damp-heat obstructing syndrome were randomly assigned to treatment group （36 cases） and the control group （36 cases）. Both groups received standard treatment and topical antibiotic bone cement for ulcer wounds， while the treatment group received oral Xiaozhong Zhitong Mixture （50 ml per time， three times daily） in additionally. Both groups underwent daily wound dressing changes for 21 consecutive days. Ulcer healing rate， serum levels of tumor necrosis factor-alpha （TNF-α）， interleukin-1 beta （IL-1β）， malondialdehyde （MDA）， superoxide dismutase （SOD）， C-reactive protein （CRP）， and white blood cell （WBC） count were observed before and after treatment， and visual analog scale （VAS） scores for wound pain， traditional Chinese medicine （TCM） syndrome scores， and the DFU Healing Scale （DMIST scale） were also compared. Liver and kidney function were evaluated before and after treatment， and adverse events such as allergic reactions， worsening ulcer pain were recorded. ResultsTotally 35 patients in the treatment group and 33 in the control group were included in the final analysis. The ulcer healing rate in the treatment group was （87.93±9.34）%， significantly higher than （81.82±12.02）% in the control group （P = 0.035）. Compared to pre-treatment levels， both groups showed significant reductions in serum CRP， WBC， MDA， IL-1β， and TNF-α levels， with an increase in SOD level （P＜0.05）. TCM syndrome scores， VAS， and DMIST scores also significantly decreased in both groups （P＜0.05）， with greater improvements in the treatment group （P＜0.05）. No significant adverse reactions were observed in either group during treatment. ConclusionXiaozhong Zhitong Mixture combined with antibiotic bone cement has significant advantages in promoting DFU healing， reducing inflammatory response， and alleviating oxidative stress in DFU patients with damp-heat obstructing syndrome， with good safety for DFU patients with damp-heat obstructing syndrome.

BACKGROUND:Persistent hyperglycemia has been identified as promoting neurovascular dysfunction,leading to irreversible endothelial dysfunction,increased neuronal apoptosis,oxidative stress and inflammation.These changes in combination or alone lead to microvascular and macrovascular lesions as well as progressive neuropathy.Noncoding RNAs may provide a new strategy for understanding the etiology,pathogenesis and treatment of the disease. OBJECTIVE:To review the role and mechanism of noncoding RNAs in the occurrence and development of diabetic peripheral neuropathy by reviewing relevant literature at home and abroad,in order to provide new ideas and approaches for noncoding RNAs in the prevention,diagnosis and treatment of diabetes neuropathy. METHODS:CNKI and PubMed were retrieved for relevant literature published from database inception to 2022.The key words were"noncoding RNA;lncRNA;miRNA;diabetes peripheral neuropathy;expression profile"in Chinese and English,respectively.The retrieved documents were summarized and analyzed,and 61 articles were finally selected for further review. RESULTS AND CONCLUSION:(1)Noncoding RNA plays a key role in the pathophysiological process of diabetic peripheral neuropathy.Among the most widely studied regulatory noncoding RNA species,there are long noncoding RNAs,circular RNAs and microRNAs.(2)Through the regulation of noncoding RNAs,the activation or inhibition of related cell pathways,inflammatory genes and downstream-related cytokines will inhibit cell apoptosis,improve inflammation,and thus change the expression of target genes to participate in the process of diabetic neuralgia.(3)Although many microRNAs and long noncoding RNAs have been found to participate in diabetic peripheral neuropathy,the mechanisms of many noncoding RNAs are unclear,and the same noncoding RNAs may play different roles in different modes.Therefore,it is necessary to further study their action modes in disease etiology and pathology,thereby clarifying their role in the pathogenesis of diabetic peripheral neuropathy.However,the criteria for evaluating noncoding RNA activity have not yet been established,and further research is needed on which specific noncoding RNAs play a dominant regulatory role.(4)MicroRNAs,long noncoding RNAs and their target genes can regulate progressive neuropathy,which are expected to become new targets for the clinical prevention and treatment of diabetic peripheral neuropathy and new biomarkers for the development and prognosis of diabetic peripheral neuropathy.

Objective:To assess the differences in multidimensional clinical manifestations between patients with irritable bowel syndrome (IBS) matching the Rome Ⅲ criteria but not matching Rome Ⅳ and IBS patients matching the Rome Ⅳ criteria, among patients diagnosed with IBS according to Rome Ⅲ criteria.Methods:From November 2016 to October 2017, a total of 472 IBS patients admitted to six hospitals were selected, which included Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology (139 cases), Sir Run Run Shaw Hospital, School of Medicine of Zhejiang University (95 cases), the First Affiliated Hospital of Dalian Medical University (96 cases), the Affiliated Hospital of Guizhou Medical University (90 cases), the People′s Hospital of Guangxi Zhuang Autonomous Region (20 cases), and the Second Affiliated Hospital of Xi′an Jiaotong University (32 cases). The 472 IBS patients were divided into the group that matching the Rome Ⅳ criteria (Rome Ⅳ group), and the group that matching the Rome Ⅲ criteria but not matching the Rome Ⅳ criteria (Rome Ⅲ group). The basic characteristics (IBS course, post-infectious IBS, history of smoking or drinking, etc.), abdominal symptoms, and defecation-related symptoms of two groups were compared and analyzed by face-to-face questionnaires. Multi-dimensional clinical manifestations assessment was completed by questionnaires, which included gastrointestinal symptom rating scale (GSRS), irritable bowel syndrome-severity scoring system (IBS-SSS), irritable bowel syndrome-quality of life (IBS-QOL), and hospital anxiety and depression scale (HADS). Independent sample t-test, rank sum test, and chi-square test were used for statistical analysis. Results:There were 344 patients (72.9%) in Rome Ⅳ group and 128 patients (27.1%) in Rome Ⅲ group. The IBS course of patients in Rome Ⅳ group was longer than that in Rome Ⅲ group (3.0 years (7.0 years) vs. 2.0 years (5.7 years)), and the difference was statistically significant ( Z=-2.73, P=0.006). The GSRS scores of loose stools and abdominal pain of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group, and the GSRS scores of increased exhaust and abdominal distension of IBS patients in Rome Ⅳ group were lower than those in Rome Ⅲ group (3.0(2.0) vs. 2.0(4.0), 3.0(2.0) vs.1.0(2.0), 1.5(3.0) vs. 2.0(3.0), 1.0 (3.0) vs. 2.0(3.0)), and the differences were statistically significant ( Z=-2.48, -9.90, -2.11 and -2.06, P=0.013, <0.001, =0.035 and =0.040). The proportions of fatigue and dizziness of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group (58.4% (201/344) vs. 43.0% (55/128), 30.8% (106/344) vs. 29.7% (38/128)), and the differences were statistically significant ( χ2=8.37 and 12.36, P=0.004 and <0.001). The scores of anxiety and depression subscales of the HADS of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group (6.5 (6.8) vs. 6.0 (6.0), 5.0 (6.0) vs. 3.0 (5.0)), and the differences were statistically significant ( Z=-2.58 and -2.40, P=0.010 and 0.017). The scores of IBS-SSS scale, abdominal pain severity, abdominal pain frequency, and impact on quality of life of IBS patients in Rome Ⅳ group were all higher than those in Rome Ⅲ group (249.5 (108.0) vs. 177.0 (111.8), 50.0 (25.0) vs. 20.0 (30.0), 50.0 (70.0) vs. 10.0 (30.0), 66.0 (42.0) vs. 42.5 (34.0)), and the differences were statistically significant ( Z=-7.79, -9.64, -10.65 and -2.48, P<0.001, <0.001, <0.001 and =0.013). The score of IBS-QOL for behavioral disorder of IBS patients in Rome Ⅳ group was lower than that in Rome Ⅲ group (74.5±21.6 vs. 79.2±17.7), and the difference was statistically significant ( t=-2.22, P=0.027). Conclusion:The clinical symptoms of patients mathching the Rome Ⅳ criteria are more typical and severe, as compared with those of IBS patients matching the Rome Ⅲ criteria but not matching the Rome Ⅳ criteria.

BACKGROUND: The onset and clinical presentation of systemic lupus erythematosus (SLE) are sex-related. Few studies have investigated the distinctions in clinical characteristics and treatment preferences in male and female SLE patients in the initial cohort. This study aimed to improve the understanding of Chinese SLE patients by characterizing the different sexes of SLE patients in the inception cohort. METHODS: Based on the initial patient cohort established by the Chinese SLE Treatment and Research Group, a total of 8713 patients (795 men and 7918 women) with newly diagnosed SLE were enrolled between April 2009 and March 2021. Of these, 2900 patients (347 men and 2553 women) were eligible for lupus nephritis (LN). A cross-sectional analysis of the baseline demographic characteristics, clinical manifestations, laboratory parameters, organ damage, initial treatment regimens, and renal pathology classification was performed according to sex. RESULTS: In the SLE group, as compared to female patients, male patients had a later age of onset (male vs. female: 37.0 ± 15.8 years vs. 35.1 ± 13.7 years, P  = 0.006) and a higher SLE International Collaborative Clinic/American College of Rheumatology damage index score (male vs. female: 0.47 ± 1.13 vs. 0.34 ± 0.81, P  = 0.015), LN (male vs. female: 43.6% vs. 32.2%, P < 0.001), fever (male vs. female: 18.0% vs. 14.6%, P  = 0.010), thrombocytopenia (male vs. female: 21.4% vs. 18.5%, P  = 0.050), serositis (male vs. female: 14.7% vs. 11.7%, P  = 0.013), renal damage (male vs. female: 11.1% vs. 7.4%, P < 0.001), and treatment with cyclophosphamide (CYC) (P < 0.001). The frequency of leukopenia (male vs. female: 20.5% vs. 25.4%, P  = 0.002) and arthritis (male vs. female: 22.0% vs. 29.9%, P < 0.001) was less in male patients with SLE. In LN, no differences were observed in disease duration, SLE Disease Activity Index score, renal biopsy pathological typing, or 24-h urine protein quantification among the sexes. In comparisons with female patients with LN, male patients had later onset ages (P  = 0.026), high serum creatinine (P < 0.001), higher end-stage renal failure rates (P  = 0.002), musculoskeletal damage (P  = 0.023), cardiovascular impairment (P  = 0.009), and CYC use (P  = 0.001); while leukopenia (P  = 0.017), arthritis (P  = 0.014), and mycophenolate usage (P  = 0.013) rates were lower. CONCLUSIONS Male SLE patients had more severe organ damage and a higher LN incidence compared with female SLE patients; therefore, they may require more aggressive initial treatment compared to female patients.

Leukoencephalopathy with vanishing white matter (VWM) is one of the most prevalent inherited childhood white-matter disorders, and the pathogenic gene has been confirmed as EIF2B gene. VWM is characterized by chronic progressive neurological deterioration with cerebellar ataxia, usually less prominent spasticity and relatively mild mental decline. There are episodes of rapid and major neurological deterioration provoked by stresses, such as fever, minor physical trauma and acute fright, which is a characteristic clinical feature of VWM. Brain magnetic resonance imaging findings are diagnostic in almost all patients,and the disappearance of the cerebral white matter occurs in a diffuse "melting away" pattern. The onset of VWM can be at any age from fetal stage to adult stage, and the clinical phenotypes vary immensely. Gene diagnosis is the golden standard for VWM. This article reported a patient with a course of 17 years, who was misdiagnosed as Wilson′s disease because of low serum ceruloplasmin, and was finally diagnosed as VWM by reinterpretation of whole exome sequencing, which is worthy of clinicians′ vigilance and consideration.

Objective:To analyze the epidemiological characteristics of novel coronavirus positive cases including confirmed cases with clinical symptoms and asymptomatic infected cases in Guangzhou.Methods:Epidemiological data were collected on the nucleic acid positive cases of COVID-19 in Guangzhou from January to September 2020. The epidemiological characteristics, the distribution of time intervals between the confirmed/isolation date and the date of the first positive detection were analyzed, at last the influencing factors for the confirmed cases and asymptomatic infected persons were discussed.Results:From January 7 to September 4 in 2020, a total of 1 097 nucleic acid positive cases were identified, including 658 confirmed cases (59.98%) and 439 asymptomatic infected cases (40.02%). Among the 658 confirmed cases, the median age was 42 years old, the cases indicated two significant peaks. one of the peaks was related to the imported and associated cases from Hubei province, and the other peak was connected with individuals from overseas. In terms of 439 asymptomatic infected cases, the median age was 32 years old. There were two stages in these cases. The first stage followed the second peak of confirmed cases, and the second stage overlapped with the confirmed cases in Guangzhou when the epidemic was in a period of normal prevention and control, mainly related to imported cases from abroad. The asymptomatic infected persons accounted for 57.32% in all the imported infected cases. In both of asymptomatic and symptomatic cases, the positive rate of pharyngeal swabs was higher than that of nasopharyngeal swabs and anal swabs. There were statistically significant differences in age, source of infection and gender composition between confirmed cases and asymptomatic infected persons ( P<0.05). Older age groups were more likely to have clinical symptoms, with ≥40 years being the risk factor for confirmed cases (OR=2.334, P=0.001), and 20-39 years less likely to have clinical symptoms (OR=0.620, P=0.047), compared with the 0-19 years old group. Compared with those infected in China, those infected abroad were less likely to develop clinical symptoms and became confirmed cases (OR=0.723, P=0.013). Women were more likely to have clinical symptoms than men (OR=1.574, P=0.001). Conclusions:At present, asymptomatic infected persons and confirmed patients with clinical symptoms co-existed, and the number of asymptomatic infected patients was higher than that of confirmed cases in Guangzhou. High age, domestic infection and female may be risk factors for confirmed cases. It was of great value to further explore these underlying mechanisms for the prevention and treatment of the COVID-19.

Objective: To understand the economic burden caused by hand-foot-mouth disease (HFMD) in Xi’an, in order to provide scientific basis for government departments to allocate health resources rationally. Methods: New cases of HFMD were selected randomly from designated hospitals in city and district level in Xi’an, 2018, Direct and indirect economic costs of patients caused by HFMD were collected using a questionnaire survey, hospital charging system inquiry as well as follow-up survey. Factors affecting the economic burden of HFMD were analyzed. Results: A total of 438 mild as well as 60 severe cases were surveyed, with the overall medical insurance participation rate of 89.76%(447/498). The median of per capita direct economic burden of mild and severe cases were 635 and 7 972 yuan respectively, and the median of per capita indirect economic burden of mild and severe cases were 130 and 233 yuan respectively, in Xi’an. The overall economic burden attributable to HFMD was 23.1 million yuan in Xi’an 2018, in which the direct economic burden was 19.3 million yuan, indirect economic burden was 3.8 million yuan. Multiple Logistic regression analysis showed that the approach of diagnosis, type of cases, days of treatment and type of pathogen had significant influence on the economic burden of HFMD(P<0.05). Conclusion The economic burden of HFMD was heavy in Xi’an. Controling and reducing the incidence rate, as well as increasing the medical insurance coverage and reimbursement rate would lighten the economic burden caused by HFMD effectively.

Objective To explore the effects of comprehensive psychological nursing intervention on patients with nasopharyngeal carcinoma during radiotherapy, so as to provide references for alleviating their physical and mental pain and to improve their quality of life. Methods From July 2016 to April 2017, a total of 124 cases of nasopharyngeal carcinoma patients treated by radiotherapy from a ClassⅢGrade A hospital were recruited in the research, of which 63 cases from July to December 2016 were assigned as control group and 61 cases from January to April 2017 were assigned as intervention group. Routine nursing care was provided in the control group. On the basis of the routine nursing, individual combined with group intervention was applied in the intervention group according to the psychological and behavioral interventions before and during radiotherapy. The nursing intervention lasted from the beginning of the first radiotherapy till the end of the therapy course in both groups. By the end of the therapy, all the patients were investigated with Distress Thermometer (DT) and the short Quality of Life Scale for Nasopharyngeal Carcinoma with 13 items (QOL-NPC13). Results The scores of DT in the control group and the intervention group were (8.08±0.58) and (5.30±1.11) respectively, and the difference was statistically significant (t=19.316,P<0.001). The scores of body function, psychological spirit, social relationship, toxic side effect and the quality of life of the intervention group were all higher than those of the control group, the differences were statistically significant (Z=-4.674,-7.894,-4.755,-4.842,-8.114; P< 0.001). Conclusions Comprehensive psychological nursing intervention is helpful to relieve the psychological pain and improve the quality of life in patients with nasopharyngeal carcinoma undergoing radiotherapy.

Background:Screening of colorectal cancer (CRC) and colorectal adenoma (CRA), the precursor of CRC, is crucial for CRC prevention.It is believed that opportunistic screening of CRC in high risk population would narrow down the screening scope and save the health resources, and is suitable for the present status in China.Aims:To analyze the performance of high risk factors in predicting CRC/CRA, for exploring the feasibility of opportunistic screening for CRC in high risk population.Methods:A total of 1 862 outpatients and health examination subjects undergoing colonoscopy from Feb.2015 to Aug.2016 at the PLA 281 Hospital were recruited and asked to complete a questionnaire of high risk factors for CRC and CRA before colonoscopy.The questionnaire was designed based on the updated consensus on the screening and management of early colorectal cancer and precancerous lesion in China.Using the results of colonoscopy as gold standard, the predictive performance of high risk factors for CRC/CRA was analyzed.Results:Four hundred and sixty-eight (25.1%) individuals with high risk factors for CRC/CRA were screened out by the questionnaire.The detection rate of CRC in individuals with high risk factors was significantly higher than those without (17.5% vs.0.9%, P=0.000).The sensitivity, specificity, positive and negative predictive values of high risk factors in predicting CRC were 87.2%, 78.2%, 17.5% and 99.1%, respectively, and the missed diagnosis rate was 12.8%.For CRC/CRA, the corresponding figures were 83.2%, 87.0%, 57.3%, 96.1% and 16.8%, respectively.The risk ratios (RR) of high risk factors for CRC and CRC/CRA were 20.35 and 14.78, respectively.Conclusions:Opportunistic screening of CRC in high risk population is feasible and applicable in China under present condition.

Objective To investigate whether apolipoprotein E (APOE) genotype specifically modulates cognition function and cerebral blood flow in patients with amnesic mild cognitive impairment (aMCI) by using pulsed arterial spin labeling (ASL) MR imaging.Methods Eighty-three aMCI subjects and 130 healthy controls (HCs) were recruited through heath screening in community from 2012 to 2014 in our hospital.They all underwent neuropsychological battery assessments,genetic screening and MR imaging.The aMCI subjects included 8 APOE ε2ε3 carriers,46 APOE ε3ε3 carriers and 29 APOE ε3ε4 carriers;however,in HCs,there were 35 APOE ε2ε3 carriers,46 APOE ε3ε3 carriers and 49 APOE ε3ε4/ε4ε4 carriers.Neuropsychological scale was performed in all subjects.ASL data were preprocessed by the ASLtbx toolbox.A voxel-wise two-way ANOVA was performed to examine the main effects of'disease'(MCI) and ‘genotype’ (APOE),and the disease-by-genotype interactions on regional cerebral blood flow (rCBF) maps.Multiple linear regression analysis was performed to examine the relationships between neuropsychological scale scores and rCBF values in brain areas showing significant diagnosis-by-genotype interactions.Results (1) As compared with HCs,the aMCI subjects exhibited significantly higher rCBF values primarily in the left superior and middle frontal gyrus (P＜0.05).APOE ε3ε4/ε4ε4 carriers showed significantly higher rCBF values in the right anterior and posterior cingulate cortex,right ventromedial prefrontal cortex/anterior cingutate than those of A POE ε2ε3 carriers and ε3ε3 carriers,respectively (P＜0.05).Significant disease-by-genotype interactions on rCBF were observed in the left superior frontal gyrus,right ventromedial prefrontal cortex/anterior cingutate and bilateral superior temporal gyrus;as compared with A POE ε2ε3 and A POE ε3ε3 carriers,APOE ε3ε4 carriers had significantly higher rCBF values in the above areas in the aMCI group (P＜0.05).(2) The rCBF values in the right anterior cingulate/medial prefomtal gyrus and superior temporal gyrus of APOE ε3ε4 carriers in aMCI group were negatively correlated with the similarity test scores (r=-0.453,P=0.014;r=-0.497,P=0.006).Conclusions The APOE genotype has disease-specific effects on cerebral perfusion;APOE genotype can specifically regulate cerebral blood perfusion in aMCI subjects.The carriers ofAPOE ε3ε4 genotype in aMCI subjects may maintain their overall cognitive function by increasing lateral ventricle-temporal lobe cerebral blood perfusion.
