Objective To evaluate the efficacy of intratympanic steroid therapy compared with systemic ster‐oid therapy on the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL) patients with damaged glu‐cose tolerance .Methods Fifty first -diagnosed unilateral ISSNHL patients with damaged glucose tolerance were randomized devided equally to the intervention group (intratympanic steroid therapy) or the control group (systemic steroid therapy) ,all patients received conventional drug therapy simultaneously .Pure-tone hearing threshold tests were performed in all patients every 3 days after the first time ,and repeated measures anova was used to assess effects of hearing recovery accompanied with time .Results The mean hearing threshold in the control group de‐creased from 85 .4 ± 5 .6 dB to 48 .2 ± 4 .9 dB ,while in the intervention group it decreased from 84 .8 ± 5 .6 dB to 31 .7 ± 4 .6 dB .Total effective rate in the intervention group (84 .00% ,21/95) was higher than that in the control group (68 .00% ,17/25)(P<0 .05) .Conclusion The intratympanic steroid therapy is more effective than systemic steroid therapy in the treatment of ISSNHL patients with damaged glucose tolerance .

Objective:To investigate the value of peripheral blood eosinophils (EOS) in predicting the therapeutic effect of sublingual specific immunotherapy (SLIT) in patients with allergic rhinitis (AR).Methods:From January 2018 to June 2020, 200 patients with AR who received SLIT in Dongguan Kanghua Hospital were evaluated for their symptoms before treatment and 6 months after treatment. The curative effect was evaluated according to the improvement of the total symptom score. The number of eosinophils, percentage of eosinophils in peripheral blood were measured before treatment. The correlation between curative effect and EOS count and EOS percentage was analyzed and the value of these two indicators in predicting the efficacy of SLIT was evaluated.Results:Of the 200 AR patients, 178 patients were confirmed to have completed the treatment course of 6months. 126 effective and 52 ineffective, the effective rates were 70.8%. There was a weak correlation between the number of EOS in peripheral blood and the percentage of EOS in peripheral blood before treatment and the efficacy of SLIT ( r=0.168, P=0.048; r=0.250, P=0.001). The area under the curve of peripheral blood EOS count was 0.380, and the percentage of peripheral blood EOS was 0.355, which were all less than 0.5. Conclusions:There was no significant correlation between the number of peripheral blood EOS count and peripheral blood EOS percentage and the efficacy of SLIT , therefore, both of blood EOS count and blood EOS percentage have no value in predicting the efficacy of SLIT.

OBJECTIVE: To analyze the characteristics of genetic variants in 134 patients diagnosed with Acute myeloid leukemia (AML). METHODS: Clinical data of the 134 patients with AML (non-acute promyelocytic leukemia) initially diagnosed at the 940th Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from June 2017 to June 2022 were retrospectively analyzed. Potential variants of AML-related genes were detected by next-generation sequencing, and the frequency of variants was analyzed by using SPSS v26.0 software, and likelihood ratio χ² test and Fisher exact test were used for data analysis. RESULTS: The patients had included 72 males and 62 females, with a gender ratio of 1.7 : 1 and a median age of 51 years (9 ~ 86 years old). One hundred twenty patients (76.1%) had harbored at least one genetic variant, including 26 (19.4%) having a single variant, 27 (20.1%) having two variants, and 49 (36.6%) having >= 3 variants. 32 (23.9%) had no detectable variants. Genetic variants detected in over 10% of the 134 patients had included NPM1 (n = 24, 17.91%), FLT3-ITD (n = 21, 15.67%), DNMT3A (n = 20, 14.93%), CEBPA (single variant; n = 14, 10.45%), TET2 (n = 14, 10.45%), and NRAS (n = 14, 10.45%). The patients were also divided into low risk, intermediate risk and high risk groups based on their chromosomal karyotypes. The mutational rates for genes in different groups have varied, with 19 patients from the low risk group harboring variants of NRAS (n = 4, 21.05%), KRAS (n = 4, 21.05%), and KIT (n = 2, 10.53%); and 96 patients from the intermediate risk group harboring variants of NPM1 (n = 24, 25.00%), FLT3-ITD (n = 20, 20.83%), DNMT3A (n = 18, 18.75%), CEBPA (n = 12, 12.50%), and TET2 genes (n = 12, 12.50%). The mutational frequencies for the 19 patients from the high risk group were ASXL1 (n = 7, 21.05%), NRAS (n = 3, 15.97%), TP53 (n = 3, 15.79%), and EZH2 (n = 2, 10.53%). A significant difference was found in the frequencies of KIT, NPM1, FLT3-ITD, DNMT3A, and ASXL1 gene variants among the low-risk, medium-risk, and high-risk groups. CONCLUSION AML patients have a high frequency for genetic variants, with 76.1% harboring at least one variant. The frequency of genetic variants have varied among patients with different chromosomal karyotypes, and there are apparent dominant variants. KIT, NPM1, FLT3-ITD, DNMT3A, and ASXL1 may be used as prognostic factors for evaluating their prognosis.

OBJECTIVETo compare the prevalence of hypertension between low birth weight infant (LBWI) women and non-LBWI women.

METHODSA retrospective cohort study was applied and 3 172 pregnant women giving births during October 1976 to December 2008 in our hospital and underwent physical check-up between 2010 and 2011 at the Kailuan medical group were included and divided into LBWI group and non-LBWI group by the history of LBWI. Prevalence of hypertension was obtained during the follow-up program. Multiple logistic regression analysis was used to assess the relative risk of hypertension.

RESULTSA total number of 3 172 women, with an average age of 42.3 years old were divided into LBWI group (n = 147) and non-LBWI group (n = 3 025), with the average birth weights of their infants were 2.31 kg and 3.39 kg, respectively. The prevalence of hypertension from the follow-up program was significantly higher in LBWI group than that in the non-LBWI group (23.8% vs. 16.9%, P < 0.05). After adjustment for other traditional risk factors, the risk of hypertension in LBWI group was 1.60 (95%CI:1.02-2.53) folds higher than that in the non-LBWI group.

CONCLUSIONPrevalence of hypertension in women with LBWI was higher than that in those women without LBWI. History of LBWI seemed to have had an increased risk to develop hypertension.

Objective:To analyze the clinical characteristics of elderly-onset gouty arthritis and risk factors of tophi.Methods:A total of 1 239 gout patients were retrospective selected in the outpatient department of the Gout Clinical Medical Center of the Affiliated Hospital of Qingdao University from 2016 to 2022. According to age of onset, they were divided into the young and middle-aged group(aged<60) consisted of 826 cases, and the elderly group(aged≥60) consisted of 413 cases. Compare the clinical characteristics of elderly with Young and Middle-aged patients.Results:The systolic blood pressure, fasting blood glucose, creatinine, regular exercise, comorbidities, and tophi in the elderly group was higher than that in the middle-aged and young group. The proportion of diastolic blood pressure, serum triglycerides, eGFR, serum uric acid, alcohol consumption rate, and family history of gout was lower than that of young and middle-aged group( P<0.05); In the elderly-onset group, the initial site of arthritis was commonly observed in the first metatarsophalangeal joint. The proportion of the first attack with the upper limb joint was higher in old age group than in young and middle age group( P<0.05). Renal underexcretion type was the main subtype in the elderly group, and the proportion of overproduction type was higher than that of the young and middle-aged group( P<0.05). The logistic regression analysis showed that age, urea nitrogen, disease duration≥10 years and family history of gout were risk factors for tophi in elderly patients( P<0.05). Conclusion:The elderly-onset gout has unique clinical characteristics, characterized by a higher prevalence of tophi, a higher rate of complications. An initial site of arthritis commonly observed in the first metatarsophalangeal joint and the predominant type of uric acid excretion is renal excretion impairment. Early diagnosis and treatment, control of blood uric acid levels, smoking cessation and alcohol, regular exercise should be applied to prevent or delay the formation of tophi.

Objective:To investigate epidemiological characteristics and macrolide-resistance of hospitalized children with Mycoplasma pneumoniae (MP) infections in Beijing from 2016 to 2019, so as to provide basis for the prevention and treatment of pediatric Mycoplasma pneumoniae pneumonia (MPP).Methods:The clinical data were analyzed retrospectively from 8 691 children hospitalized with community acquired pneumonia in Beijing Children′s Hospital between January 2016 and September 2019.MP RNA was detected by simultaneous amplification and testing (SAT), and macrolide resistance of MP was examined by MP and macrolide-resistant isolate diagnostic kit (PCR with fluorescence probes). Chi- square test was used for categorical analysis. Results:Among 8 691 cases detected by SAT, the overall detection rate of MP was 28.10% (2 442/8 691 cases). The detection rates of MP from 2016 to 2019 were 26.23%, 31.36%, 27.84 % and 26.57%, respectively.The detection rate of MP in 2017 was significantly higher than that in other years ( χ2=16.11, P<0.05). The detection rate of MP in females was 29.65%(1 107/3 733 cases), which was evidently higher than that in males 26.93%(1 335/4 958 cases) ( χ2=7.85, P<0.05). The positive rates of MP in summer[32.21% (726/2 254 cases)] and autumn[39.76%(852/2 143 cases)] were significantly higher than those in spring[17.00% (327/1 924 cases)] and winter[22.66%(537/2 370 cases)] ( χ2=315.15, P<0.001). The percentages of MP were 35.06%(732/2 088 cases) in preschoolers and 37.71%(1 160/3 076 cases) in school-age children, which were significantly higher than 11.20%(232/2 072 cases) in infants and 22.01% (318/1 445 cases) in toddlers ( χ2=509.89, P<0.001). Macrolide resistance detection was conducted in 1 524 patients by fluorescent PCR.Among them, 1 386 patients were positive for drug resistance, and the positive rate was 90.94%.The prevalence of macrolide-resistant MP from 2016 to 2019 were 88.19%, 90.93%, 90.56% and 92.90%, respectively.Macrolide-resistant rates were not related with gender, age and season. Conclusions:MP can be detected in all seasons, but most prevalently in summer and autumn.Girls are more prone to MP infections than boys.The detection rate of MP increases with age, and the positive rate is higher in preschoolers and school-age children.During the 4-year study period, the drug resistant rate of MP remain high.

【Objective】 To investigate the causes of abnormal decrease in maximum amplitude(MA) of thromboelastography(TEG) and its effect on prognosis by monitoring the changes of coagulation-related indexes in emergency trauma patients. 【Methods】 A total of 319 cases of trauma patients admitted to our hospital from September 2020 to September 2023 were retrospectively analyzed, and the coagulation-related indexes of 0 h and 24 h after admission were observed. According to the MA results, they were divided into normal MA group(>50 mm) and reduced MA group(≤50 mm) to compare the hemoglobin(Hb), platelets count(Plt), activated partial thromboplastin time(APTT), prothrombin time(PT), fibrinogen(Fib), thrombin time(TT), D-dimer(D-D), coagulation reaction time(R), clot formation kinetics(Angle), 30 min clot dissolution rate(Ly30), MA, thrombine-antithrombin complex(TAT) and plasminase-α2 plasminase inhibitor complex(PIC). The correlation between MA and fibrinolysis indexes in 319 trauma patients was analyzed. According to whether tranexamic acid(TXA) was used, the reduced MA group was divided into a TXA group and a non-drug group. The differences in the change of the above coagulation-related indexes, mortality rate and changes in blood product dosage were compared between the two groups. 【Results】 Compared with the normal MA group, Hb, Plt, Fib, diastolic blood pressure and GCS scores decreased, while heart rate, ISS score and mortality increased significantly in the reduced MA group(P<0.05). The R, PT and TT were prolonged significantly(P<0.05), and PIC and D-D increased significantly(P<0.05) in the reduced MA group. Correlation analysis found that MA had no correlation with Ly30, TAT and APTT, but was correlated with Angle(r=0.803), Plt(r=0.544), Fib(r=0.581), PIC(r=-0.443) and D-D(r=-0.343). Compared with the non-drug group, the change of Angle, MA and FIB in the TXA group increased significantly(P<0.05), while the change of PIC decreased(P<0.05). Cryoprecipitate and platelet transfusion in the TXA group reduced significantly(P<0.05), and red blood cell transfusion had a decreasing trend, but the difference was not significant(P>0.05). The mortality rate in the TXA group was reduced significantly(P<0.05). 【Conclusion】 Hyperfibrinolysis may be an important factor in the abnormal decrease of MA in emergency trauma patients. Treatment with TXA can improve its effect on MA, and reduce the transfusion of blood products and the patient mortality.

The Omicron family of SARS-CoV-2 variants are currently driving the COVID-19 pandemic. Here we analyzed the clinical laboratory test results of 9911 Omicron BA.2.2 sublineages-infected symptomatic patients without earlier infection histories during a SARS-CoV-2 outbreak in Shanghai in spring 2022. Compared to an earlier patient cohort infected by SARS-CoV-2 prototype strains in 2020, BA.2.2 infection led to distinct fluctuations of pathophysiological markers in the peripheral blood. In particular, severe/critical cases of COVID-19 post BA.2.2 infection were associated with less pro-inflammatory macrophage activation and stronger interferon alpha response in the bronchoalveolar microenvironment. Importantly, the abnormal biomarkers were significantly subdued in individuals who had been immunized by 2 or 3 doses of SARS-CoV-2 prototype-inactivated vaccines, supporting the estimation of an overall 96.02% of protection rate against severe/critical disease in the 4854 cases in our BA.2.2 patient cohort with traceable vaccination records. Furthermore, even though age was a critical risk factor of the severity of COVID-19 post BA.2.2 infection, vaccination-elicited protection against severe/critical COVID-19 reached 90.15% in patients aged ≽ 60 years old. Together, our study delineates the pathophysiological features of Omicron BA.2.2 sublineages and demonstrates significant protection conferred by prior prototype-based inactivated vaccines.
