Systemic lupus erythematosus complicated with pure red cell aplasia:a case report and literature review / 上海交通大学学报（医学版）

This article reports a single case of a patient with systemic lupus erythematosus(SLE)combined with pure red cell aplasia(PRCA),and reviews 51 additional cases of patients reported by domestic and overseas papers from 1974 to 2021.These 52(51+1)cases were analyzed to summarize the epidemiological features,clinical features,laboratory inspections,treatments and prognosis of the patients.The results indicated that among all the 52 cases,cases of SLE combined with PRCA were mostly seen in Asian childbearing age women.The median ages of patients diagnosed with SLE and diagnosed with PRCA were 31.5 years and 36.0 years,respectively.The time interval between the initial diagnosis of SLE and subsequent diagnosis of PRCA was significantly longer than the interval for the initial diagnosis of PRCA,suggesting a delayed onset of SLE in these patients(P=0.042).Various clinical features of the 52 patients were reported,including mostly fatigue,joint pains,Raynaud phenomena and rashes,and SLE maybe combined with autoimmune hemolytic anemia(AIHA),thymoma,hypothyroidism and myasthenia gravis(MG).In these reported cases,laboratory indicators showed higher proportions of antinuclear antibody(ANA),anti double stranded DNA antibody(anti-dsDNA antibody),positive urinary protein and low complement levels.Among the 52 patients,51 cases(98.08%)were treated with glucocorticoids,followed by blood transfusion,cyclosporin A,cyclophosphamide and high-dose intravenous immunoglobulin.Of the 50 patients whose prognoses were reported,44 showed improvement,while 3 treatments were not effective and 3 resulted in death.This article aims to enhance the understanding of SLE combined with PRCA among doctors.

Klinefelter syndrome with partial androgen insensitivity syndrome: a case report and literature review / 中华实用儿科临床杂志

The clinical data of a patient with Klinefelter syndrome (KS) complicated by partial androgen insensitivity syndrome (PAIS) was retrospectively analyzed.The patient, a 2-month-and-22-day-old baby, was admitted to Children′s Hospital Affiliated to Zhengzhou University due to abnormal external genitalia in October 2021.Upon birth, the patient exhibited abnormal external genitalia, manifested as clitoral hypertrophy.Hormonal examinations were consistent with those of peers, while chromosomal analysis revealed 47, XXY.Due to the severe undermasculinization, whole exome sequencing was conducted, indicating a heterozygous variant of the AR gene (c.1847G>A, p.Arg616His). The patient was diagnosed with PAIS, and her elder sister was diagnosed with complete androgen insensitivity syndrome.For further treatment, a multidisciplinary comprehensive evaluation is needed.This is a rare case of KS combined with PAIS, suggesting the possibility of AR gene mutations in KS children with severe undermasculinization.

Objective:To retrospectively analyze a pediatric case of X-linked hypophosphatemic rickets treated with Burosumab and improve clinicians′ awareness of the safety and effectiveness of the drug.Methods:Clinical data of the child were collected. Whole-exon genetic testing after parental consent confirmed X-linked hypophosphatemic rickets. During 18 months of Burosumab treatment, fasting blood phosphorus, alkaline phosphate, calcium, and calcium phosphate product were monitored every 11-14 days. Parathyroid hormone and 25 hydroxyvitamin D were checked every 2-6 weeks, while knee spacing, liver and kidney function, urinary calcium creatinine ratio, electrocardiogram were assessed every 3 months. Radiological imaging was performed every 6 months, with continuous follow-up of the child.Results:Whole-exon sequencing results showed a c. 1080_1081insCAATGTTA(p.T361Qfs*3) spontaneous heterozygous frameshift mutation in the PHEX gene in the child, which has not been reported previously. After the patient was treated with Burosumab for 18 months, the biochemical indexes were significantly improved, and the rickets score was reduced, without gingival abscess or other adverse events.Conclusion:The variant c. 1080_1081insCAATGTTA(p.T361Qfs*3) in the PHEX gene was identified as the cause of the patient′s condition. Burosumab, as a targeted therapeutic agent for X-linked hypophosphatemic rickets, showed significant treatment efficacy.

@#Objective To analyze and compare the treatment of HeppleⅤ talus osteochondral injury(OLT)with autologous periosteal iliac bone graft and allogeneic bone powder combined with platelet rich gel(PRP).Methods Totally 62 HeppleⅤOLT patients admitted to our hospital from October 2018 to October 2022 were selected as the research subjects.They were divided into a transplantation group(31 patients received autologous periosteal iliac bone transplantation treatment)and a combination group(31 patients received allogeneic bone powder combined with PRP treatment)based on their treatment methods.Conduct a 12 month postoperative outpatient follow-up study on patients,evaluate and compare the treatment effectiveness,ankle joint range of motion(ROM),American Society of Orthopedic Foot and Ankle Surgeons(AOFAS)ankle posterior foot score,pain score,satisfaction,and incidence of complications between the two groups of patients at 12 months after surgery.Results The total effective rate of the transplantation group(96.77%)was not significantly different from that of the combination group(93.55%,P>0.05).At 12 months after surgery,the ROM and AOFAS scores of both groups improved(P<0.05),and there was no statistically significant difference between the groups(P>0.05).At 1 month,3 months,6 months,and 12 months after surgery,the pain scores of both groups decreased compared to before surgery(P<0.05).The subjective overall satisfaction of patients in the transplantation group(77.42%)was lower than that in the combination group(96.77%,P<0.05).The total incidence of complications in the transplantation group(19.35%)was significantly higher than that in the combination group(3.23%,P<0.05).Conclusion Allogeneic bone powder combined with PRP can avoid additional surgical incisions,increase patient subjective satisfaction,and increase the incidence of postoperative complications.

Cigarette Smoke Extract-TreatedMouse Airway Epithelial Cells-Derived Exosomal LncRNA MEG3 Promotes M1 Macrophage Polarization and Pyroptosis in Chronic Obstructive Pulmonary Disease by Upregulating TREM-1 via m6A Methylation

Cigarette smoke extract (CSE)-treated mouse airway epithelial cells (MAECs)-derived exosomes accelerate the progression of chronic obstructive pulmonary disease (COPD) by upregulating triggering receptor expressed on myeloid cells 1 (TREM-1); however, the specific mechanism remains unclear. We aimed to explore the potential mechanisms of CSE-treated MAECs-derived exosomes on M1 macrophage polarization and pyroptosis in COPD. In vitro, exosomes were extracted from CSE-treated MAECs, followed by co-culture with macrophages.In vivo, mice exposed to cigarette smoke (CS) to induce COPD, followed by injection or/and intranasal instillation with oe-TREM-1 lentivirus. Lung function and pathological changes were evaluated. CD68 + cell number and the levels of iNOS, TNF-α, IL-1β (M1 macrophage marker), and pyroptosis-related proteins (NOD-like receptor family pyrin domain containing 3, apoptosis-associated speck-like protein containing a caspase-1 recruitment domain, caspase-1, cleaved-caspase-1, gasdermin D [GSDMD], and GSDMD-N) were examined. The expression of maternally expressed gene 3 (MEG3), spleen focus forming virus proviral integration oncogene (SPI1), methyltransferase 3 (METTL3), and TREM-1 was detected and the binding relationships among them were verified. MEG3 increased N6-methyladenosine methylation of TREM-1 by recruiting SPI1 to activate METTL3. Overexpression of TREM-1 or METTL3 negated the alleviative effects of MEG3 inhibition on M1 polarization and pyroptosis. In mice exposed to CS, EXO−CSE further aggravated lung injury, M1 polarization, and pyroptosis, which were reversed by MEG3 inhibition. TREM-1 overexpression negated the palliative effects of MEG3 inhibition on COPD mouse lung injury. Collectively, CSE-treated MAECs-derived exosomal long non-coding RNA MEG3 may expedite M1 macrophage polarization and pyroptosis in COPD via the SPI1/METTL3/TREM-1 axis.

Effects of different doses of remimazolam combined with remifentanil on stress response and cognitive function in gastrointestinal endoscopy in the elderly patients / 中国药师

Objective To investigate the effect of appropriate dosage of remimazolam in combination with remifentanil on stress response and cognitive function in elderly patients gastrointestinal endoscopy.Methods Elderly patients undergoing gastrointestinal endoscopy in the Department of Anesthesiology and Pain of the First People's Hospital of Yongkang from June 2021 to June 2023 were selected as the study subjects and were divided into group A(0.15 mg·kg-1),group B(0.20 mg·kg-1)and group C(0.25 mg·kg-1)according to the different doses of remimazolam.Modified alertness/sedation(MOAA/S)scores,anesthesia-related indexes(first sedation success,gastrointestinal endoscopy time awakening time,and discharge time),stress-related indexes[cortisol(COR),epinephrine(ADR)and adrenocorticotropic hormone(ACTH)],mini-mental status examination(MMSE)scores and anesthesia-related adverse reactions were compared among the three groups.Results A total of 186 patients were included in the study,with 62 patients in each group.The MOAA/S scores of groups B and C were significantly lower than those in group A(P<0.05)immediately after gastrointestinal endoscopy,3 min and 6 min for gastroenteroscopy.The success rate of first sedation in groups B and C was significantly higher than that in group A,while the time of gastrointestinal endoscopy was significantly lower than that in group A,and the time of awakening and leaving the room were significantly longer than those in group A(P<0.05).The levels of COR,ADR and ACTH immediately after gastrointestinal endoscopy in groups B and C were significantly lower than those in group A(P<0.05).The MMSE scores of groups B and C at 10 min and 30 min after wake were significantly higher than those in group A(P<0.05).The total incidence of adverse reactions in group B was significantly lower than that in groups A and C(P<0.05).Conclusion 0.20 mg·kg-1 and 0.25 mg·kg-1 remimazolam for geriatric gastrointestinal endoscopy have better sedative effect,can reduce the degree of stress response,and have less impact on cognitive function,but the dose of 0.25 mg·kg-1 can lead to an increase in the incidence of hypotension and hypoxemia,and the recommended dose of remimazolam in geriatric gastrointestinal endoscopy is 0.20 mg·kg-1.

Five patients with 11β-hydroxylase deficiency due to CYP11B1 gene mutation: A case study / 中华内分泌代谢杂志

Objective:To investigate the clinical and molecular characteristics of 11β-hydroxylase deficiency(11β-OHD) to improve the understanding of this disorder.Methods:The clinical manifestation, hormone level, imaging examination, characteristics of gene variation and follow-up of five patients with 11β-OHD diagnosed in Henan Children′s Hospital from 2016 to 2021 were carefully reviewed.Results:Among the 5 children, 3 were male and 2 were female, all without positive family history. The age at diagnosis was 1 year 5 months to 7 years(average 3 years and 9 months), and the bone age was 3 years 6 months to 16 years(average 10 years and 3 months). Two cases were misdiagnosed as 21-hydroxylase deficiency(21-OHD) and treated with long-term mineralocorticoids. Three patients presented with hypertension and one patient had testicular adrenal rest tumor. Adrenal CT showed bilateral adrenal hyperplasia in five patients. ACTH, 17-hydroxyprogesterone, testosterone, and androstenedione levels were increased in 5 children, and hypokalemia occurred in 1 patient. One patient carried homozygous novel missense variant, and four patients had compound heterozygous variants. Four patients carried missence mutations, two patients had deletion and one patient harbored a chimeric CYP11B2 exon1-6/CYP11B1 exon7-9. Three novel CYP11B1 mutations, including c. 1385T>C(p.L462P), c.64C>T(p.Q22*)and c. 1354G>A(p.G452R) were identified. The final height of 2 male children were 164.4 cm and 150.2 cm, respectively, and the related hormone levels of the other 3 children were normal.Conclusion:11β-OHD is easily misdiagnosed, leading to severe impairment of final height. CYP11B1 gene variation is complex and diverse, which requires variety of gene detection methods.

Penicillium marneffei infection after renal transplantation: one case report / 中华器官移植杂志

Clinical data were retrospectively reviewed for one case of penicillium marneffei infection after renal transplantation (RT) to explore a proper management of peniciliosis marneffei (PSM)transplantation.This case had a history of pulmonary tuberculosis and underwent RT due to uremia.After discharging, postoperative recovery was excellent.Recurrent cough occurred at Month 7 post-operation.Fiberoptic bronchoscopy and pulmonary CT indicated a possibility of pulmonary tuberculosis.However, a definite diagnosis of PSM was confirmed by next generation sequencing (NGS) and pathogenic bacteria culture of alveolar lavage fluid.After adjusting immunosuppressive agents and regular antifungal treatment with voriconazole, respiratory symptoms improved and pulmonary CT hinted at a resorption of lesion.Features of pulmonary CT and bronchoscopic examination were nearly similar to those of tuberculosis.Thus early bacterium culture and NGS may aid an definite diagnosis.Voriconazole is an effective treatment of the disease.

Differential expression analysis of microRNAs and mRNAs in the mouse hippocampus of post-stroke depression (PSD) based on transcriptome sequencing.

To clarify the differential expressions of microRNAs and mRNAs in a PSD model, this study employed PSD mice for model construction by injecting vasoconstrictor ET-1 (angioendothelin-1) into the medial prefrontal cortex (mPFC) of mice. The animals underwent elevated plus maze test, open field test, tail suspension test, and forced swimming test subsequently. Transcriptome sequencing was performed to analyze the differentially expressed mRNAs and microRNAs. The results showed that open arm entries and time of PSD mice were markedly decreased. Times of the entry to center for mice in the model group were apparently decreased. The climbing time of mice in the model group was greatly decreased. The behavior of PSD mice indicated a marked change, and several indicators of the behavioral tests were significantly lower than those of the control group. Transcriptome sequencing analysis demonstrated that expressions of 1 206 genes and 21 microRNAs were markedly upregulated in model group, whereas expressions of 2 113 genes and 32 microRNAs were markedly downregulated. GO analysis revealed that the differentially expressed genes were mainly involved in regulatory pathways of single-multicellular organism process, developmental process, cell periphery, plasma membrane, and neuron projection. Meanwhile, KEGG analysis results indicated that the differentially expressed genes mostly participated in signaling pathways of neuroactive ligand-receptor interaction, calcium signaling pathway, and cytokine-cytokine receptor interaction. In conclusion, differentially expressed microRNAs and mRNAs were screened, which offers a theoretical foundation for further investigation of molecular mechanisms and novel insight for the early identification, prevention, and treatment of PSD.

Appearance and stature troubles are issues mostly concerned among college students. Psychological evaluation for students with Class Ⅲ malocclusion should be especially emphasized when administrating orthodontic treatment.

Changing trend of incidence and mortality of esophageal cancer during 2010-2016 in Henan Province, China / 中华肿瘤杂志

Objective: To estimate the incidence and mortality of esophageal cancer in 2016 and their changing trend during 2010-2016 according to the cancer registration data in Henan province. Methods: The data quality including completeness, validity, and reliability of local registries which submitted the cancer registration data of 2016 were assessed according to the criteria of Guideline on Cancer Registration in China and IARC/IACR. Esophageal cancer cases (ICD10: C15) were extracted from the database, and the incidence and mortality stratified by gender, age, and areas (urban/rural) were calculated, the incidence and mortality of provincial cancer were estimated combined with provincial population data. China's 2000 census population and Segi's population were used to calculate the age-standardized rate. Joinpoint model was used to estimate the changing trend of age standardized incidence and mortality along with the calendar year. Results: Approximately 40.10 thousand new esophageal cancer cases were diagnosed in Henan in 2016, accounting for 13.46% of all new cancer cases, and it ranked the third among cancer of all sites. The crude incidence of esophageal cancer was 37.21/100 000 with an age-standardized incidence rate by China standard population (ASIRC) of 26.74/100 000 and an age-standardized incidence rate by world standard population (ASIRW) of 27.12/100 000. The incidence of esophageal cancer in males was higher than that in females, with the ASIRC of 34.53/100 000 and 19.19/100 000, respectively. It was higher in rural areas than that in urban areas, with the ASIRC of 28.13/100 000 and 20.90/100 000, respectively. About 29.30 thousand deaths of esophageal cancer in Henan in 2016, accounting for 15.61% of all cancer deaths in Henan, which ranked the third among cancer of all sites. The crude mortality rate was 27.14/100 000 with an age-standardized mortality rate by China standard population (ASMRC) of 18.74/100 000 and an age-standardized mortality rate by world standard population (ASMRW) of 18.78/100 000. The mortality in males was higher than that in females, with the ASMRC of 24.78/100 000 and 13.12/100 000, respectively. It was also higher in rural areas than that in urban areas, with the ASMRC of 19.48/100 000 and 15.73/100 000, respectively. The ASIRC and ASMRC were declining with annual percent change (APC) of 3.12% (APC=-3.12%; 95%CI: -5.30%, -0.90%; P=0.015) and 2.47% (APC=-2.47%; 95%CI: -4.70%, -0.20%; P=0.039) during 2010-2016. However, the significant declining trend was only observed in rural areas in Henan, and the changing trend was same between males and females. Conclusions: The incidence and mortality of esophageal cancer are declining since 2010, however, the disease burden remains large in Henan. Therefore, comprehensive prevention and control efforts should be strengthened according to its epidemic characteristics and risk factors.

Changing trend of incidence and mortality of stomach cancer during 2010-2016 in Henan Province, China / 中华肿瘤杂志

Objective: To estimate stomach cancer incidence and mortality in Henan, 2016 and analyze the trend of stomach cancer incidence and mortality from 2010 to 2016. Methods: Stomach cancer related data in 2016 was extracted from Henan cancer registration and follow-up system. All data were qualified in validity, reliability and completeness according to the Guideline on Cancer Registration in China and International Agency for Research on Cancer (IARC/IACR). The incidence and mortality of stomach cancer were estimated by areas, gender and age based on the quality data and the registered population data of Henan province in 2016. The epidemic trend of stomach cancer was also been evaluated based on the age-standardized incidence and mortality by Chinese population (ASR China) from 2010 to 2016. Results: In 2016, the estimated incident cases of stomach cancer were 44 311. The incidence was 41.07/100 000, ASR China was 30.17/100 000, ASR by world population (ASR world) was 30.36/100 000, and the cumulative incidence rate was 3.84%. The incidences of male and female were 55.65/100 000 and 25.35/100 000, respectively. Meanwhile, 32 927 people died of stomach cancer in Henan. The mortality was 30.52/100 000, ASR China was 21.45/100 000, ASR world was 21.54/100 000, and the cumulative mortality was 2.53%. From 2010 to 2016, both the ASR China for incidence and mortality of stomach cancer in Henan showed a steady downward trend. In rural, the ASR China for incidence and mortality decreased rapidly, while the stable trend was observed in urban. Nevertheless, the incidence and mortality of stomach cancer in rural were still higher than those in urban. Conclusions: The incidence and mortality of stomach cancer in Henan province showed steadily declining trend from 2010 to 2016, and the geographical distribution difference between rural and urban areas was gradually narrowing. However, the disease burden was still high in 2016.

The YLDs of patients with disease vs - P complications was higher than that of patients without complications [(8.55±3.95) (7.87±3.21) person years, <0.01]. The total - - DALYs of the patients was 14 031.59 person years, and the average per capita DALYs was 8.51 person years. Its YLDs accounted for 82.0 % of the total DALYs. The total economic loss caused by CWP in the 1 405 surviving patients was 354.903 0 Conclusion million yuan, and the average per capita economic loss was 252 600 yuan. The disease burden caused by CWP is relatively high in Anhui Province. In addition to early detection, diagnosis and treatment, it is necessary to focus on prevention and treatment of CWP complications to reduce the disease burden.

Expression and significance of serum microRNA-122 in children with nonalcoholic fatty liver disease / 中华内分泌外科杂志

Objective:To study the expression of serum microRNA-122 (miR-122) in children with non-alcoholic fatty liver disease (NAFLD) .Methods:35 NAFLD children aged 7-14 years from the department of Endocrinology and Inherited Metabolic disease, Children’s Hospital Affiliated to Zhengzhou University were collected, and 43 healthy children healthy children matched with the gender and age as the control group. The height, weight, body mass index (BMI) , waist-hip ratio (WHR) , triglyceride (TG) , cholesterol (TC) , alanine transaminase (ALT) , aspartate aminotransferase (AST) and miR-122 levels of the children in the two groups were detected and recorded.Results:There was no significant difference in age between NAFLD group (9.97±1.93 years) and control group (10.28±1.68 years) ( P=0.455) . Body weight (65.91±15.94kg) , BMI (29.93±3.77kg/m2) , WHR (0.97±0.04) , TG (1.49±0.46mmol/L) , TC (3.96±0.67mmol/L) , ALT (32.7±15.65U/L) and the level of miR-122 (2.33±1.75) in the NAFLD group was higher than that in the control group (36.93±7.54kg, 17.75±1.60kg/m 2, 0.83±0.04, 0.94±0.18mmol/L, 3.55±0.53mmol/L, 19.77±4.3U/L) , the differences were statistically significant ( P<0.05) . The levels of miR-122 in the NAFLD group were positively correlated with ALT and AST (r=0.618, 0.487, P < 0.05) . The ROC curve was used to evaluate the efficacy of miR-122 in diagnosing NAFLD, and the area under the curve of miR-122, ALT and ALT+ miR-122 in diagnosing NAFLD was 0.824, 0.727 and 0.839, respectively. MiR-122 combined with ALT had an advantage in diagnosing NAFLD. Conclusion:The levels of miR-122 in children with NAFLD were positively correlated with ALT. MiR-122 combined with ALT has clinical value in diagnosing NAFLD.
