navirus disease 2019 (COVID-19) in the patients younger than 18 years old infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant, and to provide a basis for determining the chest CT changes and efficacy of COVID-19 caused by Omicron virus variant in patients younger than 18 years old. Methods The clinical and imaging data of 30 cases of patients younger than 18 years old infected with COVID-19 Omicron variant, who admitted to the Third People's Hospital of Shenzhen from February 11 to March 26, 2022 were collected and retrospectively analyzed. The clinical manifestations, imaging features and dynamic changes of lesions were summarized. Results A total of 41 intrapulmonary lesions in 30 patients with COVID-19 caused by SARS-CoV-2 Omicron variant. The main manifestations were patchy or nodular ground-glass opacities and/or consolidation, with focal subpleural distribution, lesions mainly occur in the right lung (70.73%, 29/41). There were 42 lesion morphologies, with 22 (52.38%) striped shadows and 16 (38.10%) nodular shadows, with small lamellar and patchy shadows predominating. There were 36 lesion density variations, with ground glass shadows being the most common, with a total of 24 ground glass shadows (66.66%) in each lobe of the lung, and also 6 consolidation lesions (16.67%) and 6 mixed ground glass opacity and consolidation lesions (16.67%). With the progression of the disease, lesions gradually enlarged, appeared on the 2nd day (312.93 mm3), peaked on the 9th day (1 837.18 mm3). The average absorption time of the lesions was (16±3) days, and there was no significant difference between the absorption time of patchy and nodular lesions (ground glass and/or consolidation) (t=0.853, P>0.05). The lesions showed focal ground-glass opacity in the early stage, 77.78% lesions were absorbed after treatment in the late stage. Inflammatory nodules were absorbed slowly (9-19 days), without residual fibrotic changes. Conclusions The imaging manifestations of COVID-19 in patients younger than 18 years old infected with SARS-CoV-2 Omicron variant have certain characteristics, showed patchy or nodular ground glass opacities and/or consolidation, mainly distributed in the subpleural area, with small and few lesions and slow change, didn't remain fibrosis. Being familiar with its clinical and imaging manifestations can assist in early diagnosis, but confirming the diagnosis requires a combination of epidemiological history, clinical symptoms, SARS-CoV-2 nucleic acid and radiological manifestations.

OBJECTIVETo evaluate the effects of periodontal treatment on the clinical response, systemic inflammatory parameters, and metabolic control of type 2 diabetes patients with moderate to severe periodontitis.
METHODSA total of 56 patients with mean clinical attachment level (CAL)>3 mm were included in the subgroup analysis. A repeated-measures ANOVA (group factor: treatment group and control group; time factor: initial visit, 1.5, 3, and 6 months) was used to analyze the probing depth (PD), CAL, bleeding on probing (BOP), high-sensitivity C-reactive protein (hsCRP), glycated hemoglobin (HbA1c), and fasting plasma glucose.
RESULTSSignificantly lower PD (F=62.898, P-0.000), CAL (F=51.263, P-0.000), BOP (F=75.164, P=0.000), hsCRP (F=6.391, P=0.010), HbA1c(F=4.536, P=0.011), and fasting plasma glucose level (F= 3.073, P=0.031) were observed after therapeutic periodontal improvement. The inter-group differences for PD (t=-2.050, P=0.045), BOP (t=-4.538, P=0.000), and hsCRP (t=-2.261, P=0.028) were statistically significant after therapy.
CONCLUSIONNon-surgical periodontal treatment can effectively improve periodontal status, circulating inflammatory status, and metabolic control of diabetic patients with moderate to severe periodontitis.

OBJECTIVE: To explore the effects of Tanreqing injection, a traditional Chinese herbal preparation for clearing heat and resolving phlegm, in treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) by improving airway inflammation and airway mucus hypersecretion. METHODS: A randomized controlled trial (RCT) was designed. Ninety AECOPD patients were randomly divided into Tanreqing group, ambroxol hydrochloride group and control group. The patients in the three groups were all treated with conventional therapy. Furthermore, intravenous drip infusion of 20 ml Tanreqing injection (once daily) and 15 mg ambroxol hydrochloride injection (twice daily) were administered respectively to the patients in the Tanreqing group and ambroxol hydrochloride group. They were all treated for 10 days. Symptom score of traditional Chinese medicine (TCM), plasma concentrations of interleukin-8 (IL-8), IL-10 and neutrophil elastase (NE) were detected before and after treatment. RESULTS: Cough, sputum amount, expectoration, dyspnea, fever, coated tongue and pulse tracings were improved obviously in Tanreqing group (P<0.05), and the effects of Tanreqing on improving cough, sputum amount and expectoration were better than the conventional therapy (P<0.05), while there was no significant difference between Tanreqing group and ambroxol hydrochloride group (P>0.05). Compared with ambroxol hydrochloride group and the control group, the coated tongue was improved obviously in Tanreqing group (P>0.05). After treatment, plasma concentrations of IL-8, IL-10 and NE were decreased in Tanreqing group and ambroxol hydrochloride group (P<0.05), and the levels of IL-8 and IL-10 in the control group were decreased (P<0.05). The change of IL-8 level before and after treatment in Tanreqing group was greater than that in ambroxol hydrochloride group and the control group. The changes of IL-10 and NE levels in ambroxol hydrochloride group were greater than those in Tanreqing group and the control group, while there was no significant difference in the changes of serum levels of IL-8, IL-10 and NE among the three groups (P>0.05). Total response rates in Tanreqing group and ambroxol hydrochloride group were higher than that in the control group (P<0.05), while there was no significant difference in total response rate between Tanreqing group and ambroxol hydrochloride group (P>0.05). There was no significant difference in total response rate among the three groups (P>0.05). CONCLUSION: Tanreqing injection can improve TCM signs and symptoms in AECOPD patients, and the mechanism maybe due to the decrease of serum levels of IL-8 and NE and improvement of IL-10 level.

AIM: To investigate the dynamic variety of frequency and function of FoxP3~+ regulatory T cells in patients with acute hepatitis B (AHB). METHODS: Peripheral blood mononuclear cells (PBMCs) from 15 AHB patients at acute phase (week 1 of illness), convalescent phase (primary occurrence of both ALT level normalization and HBsAg negative conversion), resolved phase (at least 8 weeks after both ALT normalization and HBsAg seroconversion, and 15 health subjects were analyzed for FoxP3 (Forkhead/winged helix transcription factor) mRNA expression in MACS magnetic beads-purified CD4~+ T cells by real-time RT-PCR assay. The effects of Treg cells on the proliferation of CD4~+CD25~- T cells were examined by a ~3[H]-thymidine incorporation assay. RESULTS: AHB patients presented a significantly higher FoxP3 mRNA expression at convalescent phase than acute phase (t=-6.04, P<0.01) and resolved phase (t=4.45, P<0.01), and healthy controls (t=3.44, P<0.01). We also observed that the suppression efficiency of Treg cells on proliferation of CD4~+CD25~- T cells was lower at acute phase than convalescent phase (t=-5.30, P<0.01) and resolved phase (t=-3.20, P<0.05), but there was no significant difference between healthy controls and any phase of AHB. CONCLUSION: AHB patients presented lower circulating Treg frequency and suppression function at acute phase, and both of them are increased at convalescent phase, and then return to normal level along with disease resolved. This follow-up study furthers our understanding of Treg' s role in immunopathogenesis of hepatitis B.

Objective To study the distribution of Candida infection and drug tolerance in intensive care unit(ICU). Methods A retrospective study was conducted. The critical patients admitted from January 2011 to December 2013 in ICU of the First Hospital of Jiaxing in Zhejiang Province were enrolled,and their clinical data with positive Candida culture and drug susceptibility results in specimens of sputum,urine,blood,ascites,bile, etc were collected. In the study of these 3 years in ICU,the situation of Candida infection,the distribution of positive specimen,the condition of distribution of different strains of Candida,and the Candida tolerance to antifungal drugs were analyzed. Results From 2011 to 2013,2 412 times of patients(including one patient had admitted into ICU for more than one time)were admitted into ICU in which 407 cases were of Candida infection(16.9%),and the rate of Candida infection was rising gradually in the 3 years〔2011 to 2013 Candida positive rates were 13.4%(77/573), 16.1%(146/907),19.7%(184/932)〕,the difference being statistically significant(P<0.01). In the 407 strains of Candida,166 strains(40.8%)were isolated from sputum,157(38.6%)from urine,53 strains(13.0%)ascites, 13 strains(3.1%)blood,11 strains(2.7%)bile,7 strains(1.7%)from other specimens. The strain distribution of Candida was mainly as follows:Candida albicans(174 strains),Candida glabrata(131 strains),Candida tropicalis (83 strains),Candida parapailosis(5 strains),Candida krusei(12 strains),and 2 strains of rare Candida portugal and Lipolztica. From 2011 to 2013,the highest tolerance of Candida albicans,Candida glabrata,Candida tropicalis to fluconazole,itraconazole,Fushita Yasu and other antifungal drugs was in 2013,and the lowest was in 2012,the rates of tolerance of the above 3 strains of Candida to amphotericin B being 0,to itraconazole being the highest(10.9%, 27.8%,9.6%,respectively),to Fushita Yasu the secondary(6.6%,11.0%,0,respectively)and to fluconazole the last(4.7%,7.4%,1.9%,respectively),and the rates of tolerance of Candida parapsilosis,Candida krusei,Candida Portugal,Candida lipolztica to amphotericin B,fluconazole,itraconazole,Fushita Yasu were all 0. Conclusion In ICU,the Candida infection is mainly in the respiratory tract and urinary tract,its rate of infection has a tendency of rising,and the rate of Candida tolerance to itraconazole is the highest.
