Objective To explore the association between the signal transducer and activator of transcription 4 (STAT4) gene polymorphism and Chinese Han systemic lupus erythematosus patients. Methods Pyrosequencing technique was used to genotype the 3 single nucleotide polymorphisms (SNP) in the samples of patients and normal individuals. Results Not only these 3 SNPs, but also the haplotypes composed by them showed significant difference between the SLE patients and normal individuals[rs11889341:P=0.012 02, OR (95%CI)=1.22( 1.044～1.424); rs7574865:P=0.003 454, 0R(95%CI)=1.25(1.076～1.451 ); rs8179673: P=0.004 275, OR (95%CI)=1.274 (1.079～1.505)]. Conclusion rs11889341, rs7574865 and rs8179673 of STAT4 are associated with the pathogenesis of Chinese Han SLE, and the STAT4 gene is a susceptibile gene for SLE in a few racial cohorts.

Objective:To optimize the culture system for the mesenchymal stem cells from the Placenta Chorion (hCMSC) in vitro by adding the selected cytokines to amplify the hCMSC effectively,with furthermore some preliminary analysis of the hCMSC performed.Methods:Immunohistochemistry was applied to show the localization of the mesenchymal stem cells within the placenta chorion,then the corresponding part of chorion was digested by collagenase Ⅳ to get the cell suspension for primary culture and subculture;Flow Cytometry was used to detect the surface marker of hCMSC,whose proliferation was detected by direct cell counting and the MTT method;then Butylated Hydroxyanisole (BHA),and DMSO was used combinedly as the inducer in the differentiation of the hCMSC to the neuron like cells,which was then detected by Immunofluorescence staining for the expression of NSE;finally RT-PCR was used to detect the expression of flt3.Results:The result of immunohistochemistry showed CD105~-,CD90~- positive hCMSC was much easier to be found around the blood vessels within the villous of chorion,which then could be obtained by mechanical dissociation and collagenase digestion.bFGF was good at amplifying the hCMSC among all selected cytokines,but FL was showed even obviously effective on the proliferation of the hCMSC.The propagating cells were found to highly express CD73,CD90,CD105;and negative for CD14,CD34,CD45 and HLA-DR.We also found that the hCMSC happened to express PDL-1 the negative co-stimulatory molecules,while their potential to different into the neuron like cells was still well maintained.Conclusion::There is low immunogenicity mesenchymal stem cells within the placenta chorion,both bFGF,FL are shown good effects on the proliferation of the hCMSC,with maintaining their differentiation potential as well.

AIM To study the effects of Rehmanniae Radix Preparata (A) and Poria (B) on decoction amounts of loganin,morroniside and 5-hydroxymethylfurfural in Corni Fructus (C).METHODS These three medicinal materials were combined one another and divided into seven groups (A,B,C,A + B,A + C,B + C and A + B + C).Then the contents of three constituents were determined by HPLC.RESULTS Compared with the single decoction of Corni Fructus,the decoction amounts of loganin and 5-hydroxymethylfurfural were decreased,and that of morroniside was increased at the time of mixed decoction of Rehmanniae Radix Preparata and Corni Fructus,or Rehmanniae Radix Preparata,Poria and Corni Fructus.This situation was just the contrary at the time of mixed decoction of Poria and Corni Fructus.CONCLUSION The mixed decoction of Corni Fructus,Rehmanniae Radix Preparata and Poria increases the decoction amount of morroniside,which may make mixed decoction liquid show better efficacy.

Objective To explore the characteristics of diagnosis and treatment of Behset's disease (BD) with meningeal thickening and to improve doctors" awareness of such diseases.Methods We reported a missed diagnosis of a patient with BD complicated with diffuse meningeal thickening,and reviewed the related literature.Results A 25-year-old young man,manifested mainly as recurrent headache,fever,recurrent oral ulcer,erythema skin nodules and folliculitis,and his cranial radiology revealed diffuse meningeal thickening and intracranial venous sinus thrombosis.We diagnosed him as neuropathy associated with BD.After the treatment with steroids,cyclophosphamide,infliximab and anti-coagulants,his symptoms improved rapidly.Conclusion In clinical,BD complicated with meningeal thickening is rare,which is easily misdiagnosed or miss-diagnosed.For the patients with unexplained meningeal thickening,the symptoms of BD,such as recurrent oral or genital ulcers,ophthalmitis and skin lesions,should be acquired in detail.In addition to steroids and immunosuppressive agents,anti tumor necrosis factor (TNF)-alpha can also be used in the treatment of BD with meningeal thickening.

Objective To investigate the effect of inhibiting the expression of RNA component of mitochondrial RNA processing endoribonuclease(RMRP)on the proliferation and invasion of human lung cancer cell line A549 in order to provide evidence to support the research on NSCLC mechanism.Methods A total of 122 cases of patients who underwent surgical treatment were selected in Jiaozuo People's Hospital from March 2016 to March 2021.In the same period,50 healthy people from physical examination center were selected as the control group.RT-qPCR was used to detect the expressions of RMRP in blood and tissues.Human lung cancer cell line A549 was cultured and divided into si-RMRP group,siRNA-NC group and blank group.RT-qPCR,CCK-8 and Transwell assays were used to detect the expression of RMRP,proliferation activity and cell counting of invasive cells.Results The rel-ative expression level of RMRP in the blood of NSCLC patients was significantly higher than that of control group(P<0.001).The relative expression level of RMRP in NSCLC tissues was significantly higher than the adjacent tissues(P<0.001).The relative expression level of RMRP in blood and tissues of patients with poorly differenti-ated,lymph node metastasis and TNM stage Ⅲ compared with moderate to highly differentiated,no lymph node metastasis and TNM stage Ⅰ-Ⅱ were significantly increased(P<0.05).The relative expression level of RMRP in the cells of the si-RMRP group was lower than that of blank and the siRNA-NC group(P<0.001).Compared with the blank group and the siRNA-NC group,the absorbance(A)value of cells at 24,48,72 and 96 h in the si-RMRP group was decreased(P<0.05).The number of invasion cells in the si-RMRP group was lower than that in the blank group and the siRNA-NC group(F=27.765,P<0.001).Conclusions The relative expression levels of RMRP in blood and tissues of NSCLC patients are increased.Down-regulation of the expres-sion of RMRP gene in A549 cells can inhibit cell proliferation and reduce cell invasion.

Objective:To understand the symptom clusters and quality of life of patients with laryngeal cancer at different times, and to explore the correlation between the two.Methods:From June 2020 to June 2021, convenience sampling was used to select 155 laryngeal cancer patients with operation in the Head and Neck Thyroid Surgery of Affiliated Cancer Hospital of Zhengzhou University as the research object. The General Information Questionnaire, the Chinese version of Anderson Symptom Inventory-Head and Neck, and Functional Assessment of Cancer Therapy Generic Scale (FACT-G) were used to investigate on the day of admission, 3 days after operation, and 30 days after operation. Symptom clusters were extracted using exploratory factor analysis. Spearman correlation analysis was used to analyze the correlation between the severity of symptom clusters and quality of life in patients with laryngeal cancer.Results:A total of 4 symptom clusters were extracted, namely pain-gastrointestinal symptom cluster, fatigue-sleep-mood symptom cluster, laryngeal cancer-specific symptom cluster, and vocalization-dysphagia symptom cluster. The number and composition of symptom clusters were different on the day of admission, 3 days after operation and 30 days after operation. There were statistically significant differences in FACT-G scores on the day of admission, 3 days after operation and 30 days after operation in patients with laryngeal cancer ( P<0.01) . The FACT-G total score and physiological dimension score on the day of admission, 3 days after operation and30 days after operation of laryngeal cancer patients were negatively correlated with the severity of different symptom clusters ( P<0.05) . Conclusions:The number and composition of symptom clusters in patients with laryngeal cancer at different times are different. The more severe the symptom clusters, the worse the quality of life. Medical and nursing staff should manage patients' symptom clusters to improve the quality of life.

Objective:To understand the symptom clusters of patients with indwelling tracheal cannula after head and neck cancer surgery, and to identify the sentinel symptoms of different symptom clusters.Methods:A total of 197 patients with head and neck cancer who underwent surgical treatment in Department of Head, Neck and Thyroid Surgery in Cancer Hospital Affiliated to Zhengzhou University (Henan Cancer Hospital) from June 2020 to December 2021 were selected as the research objects by the convenient sampling method. On the 7th day after surgery, general information questionnaire and Anderson Symptom Inventory, Head and Neck Module were used, and exploratory factor analysis was used to extract symptom clusters. Apriori association analysis was used to identify sentinel symptoms in the symptom clusters.Results:There were 4 symptom clusters in patients with indwelling tracheal cannula after head and neck cancer surgery, including head and neck cancer-specific symptom cluster, pain-digestive tract symptom cluster, voice/swallowing disorder symptom cluster and fatigue-sleep-emotional symptom cluster. Oral and throat mucus was the sentinel symptom of head and neck cancer-specific symptom cluster, nausea was the sentinel symptom of pain-digestive tract symptom cluster, numbness and needling sensation were the sentinel symptom of voice/swallowing disorder symptom cluster, sadness was the sentinel symptom of fatigue-sleep-emotional symptom cluster.Conclusions:Patients with indwelling tracheal cannula after head and neck cancer surgery have more symptoms, which are combined into symptom clusters, and sentinel symptoms exist in each symptom cluster, suggesting that medical workers should take sentinel symptoms as the entry point for symptom cluster management to achieve effective management of symptoms.

Objective:To explore the symptom cluster characteristics of early postoperative patients with head and neck cancer and analyze its influencing factors.Methods:From June 2020 to June 2022, convenience sampling was used to select 230 head and neck cancer patients who underwent surgery in the Head and Neck Thyroid Surgery of Henan Cancer Hospital as the research subject. The questionnaire survey was conducted using the Demographic and Disease Characteristics Questionnaire, Chinese version of M.D. Anderson Symptom Inventory-Head & Neck, Self-perceived Burden Scale for Cancer Patient, and Medical Outcome Study Social Support Scale. Exploratory factor analysis and multiple linear regression analysis were used for statistics.Results:A total of 230 questionnaires were distributed, and 215 qualified questionnaires were collected, with an effective rate of 93.48%. Postoperative patients with head and neck cancer had four symptom clusters, including pain-gastrointestinal symptom cluster, fatigue-sleep-emotional symptom cluster, head and neck cancer-specific symptom cluster, and vocal/swallowing disorders symptom cluster. Medical social support, per capita monthly income of families, type of head and neck cancer, self-perceived burden and complications were the influencing factors of pain-gastrointestinal symptom cluster ( P<0.05). Medical social support, disease staging, complications, self-perceived burden, and per capita monthly income of families were the influencing factors of fatigue-sleep-emotional symptom cluster ( P<0.05). Medical social support, complications, treatment methods, and type of head and neck cancer were the influencing factors of head and neck cancer-specific symptom cluster ( P<0.05). Medical social support, complications, treatment methods, course of disease, and per capita monthly income of families were the influencing factors of vocal/swallowing disorders symptom cluster ( P<0.05) . Conclusions:Postoperative patients with head and neck cancer have multiple symptom clusters and are influenced by psychological, social, and disease factors. Medical and nursing staffs should pay attention to the symptom cluster of postoperative head and neck cancer patients with low levels of social support, heavy self-perceived burden, and complications, and scientifically formulate interventions to reduce the burden of patient symptom cluster and promote rehabilitation.

2019 novel coronavirus(2019-nCoV) outbreak is one of the public health emergency of international concern.Since the 2019-nCoV outbreak, China has been adopting strict prevention and control measures, and has achieved remarkable results in the initial stage of prevention and control.However, some imported cases and sporadic regional cases have been found, and even short-term regional epidemics have occurred, indicating that the preventing and control against the epidemic remains grim.With the change of the incidence proportion and the number of cases in children under 18 years old, some new special symptoms and complications have appeared in children patients.In addition, with the occurrence of virus mutation, it has not only attracted attention from all parties, but also proposed a new topic for the prevention and treatment of 2019-nCoV infection in children of China.Based on the second edition, the present consensus further summarizes the clinical characteristics and experience of children′s cases, and puts forward recommendations on the diagnostic criteria, laboratory examination, treatment, prevention and control of children′s cases for providing reference for further guidance of treatment of 2019-nCoV infection in children.
