Objective To investigate the antimicrobial resistance of clinical isolates from a hospital in Chongqing during one year according to CHINET project.Methods Disc diffusion test (K-B method) was employed to study the antimicrobial resistance. WHONET5 was used for data analysis.Results In one year period from 2004 to 2005,690 non-duplicate isolates were collect- ed.Enterobacter isolates showed the lowest resistance rate to imipenem and meropenem.About 37.5% of E.coli and 31.4% of K.pneumoniae isolates produced ESBLs,respectively.All ESBLs-producing strains were susceptible to imipenem and mer- openem.About 37.2%,39.4% and 48.9% of P.aeruginosa isolates were resistant to imipenem,meropenem and ceftazidime, respectively.Pandrug-resistant (PDR) P.aeruginosa was isolated from our hospital.All strains of A.baumannii were sus- ceptible to imipenem and meropenem.About 37.7% of A.baumannii were resistant to cefoperazone-sulbactam.Twenty-nine strains showed the same resistant pattern among non-susceptible strains of A.baumannii,mainly derived from 2 clones by PFGE analysis.Conclusions The surveillance results suggest that prevalent strain resistant to cefoperazone-sulbactam may pres- ent in some ICUs.Resistance rate to cefoperazone-sulbactam increased significantly.

ObjectiveTo find out if the immune system derived thyroid stimulating hormone(TSH) β splice variant(TSHβ-Ⅴ) would be regulated by circulating thyroid hormone levels to get a further understanding of the function and mechanism of this TSHβ-Ⅴ in thyroid homeostasis.MethodsA total of 20 weaning Balb/c mice (half male and half female) were selected and randomly divided into two groups according to their body mass and gender(n =10).Mice of control group were fed with common diet and deionized water.Mice of the low-iodine(LI) group were fed with low-iodine diet(containing iodine 20 - 40 μg/kg,iodine-intake about 0.25 μg/d) and deionized water.The experimental period was 3 months.At the end of the experiment,mice were executed and the blood was collected to observe the levels of TSH and thyroid hormone by chemiluminescence immunoassay (CIA) ; bone marrow (BM),peripheral blood(PBL),thyroid gland and pituitary were collected to assay the TSHβ-Ⅴ mRNA expression by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR).ResultsThe serum free thyroxine(FT4) and total thyroxine(TT4) levels in LI group of mice[(0.47 ± 0.70)nmol/L,(2.41 ± 0.28)pmol/L] were significantly lower than that of the control group of mice [(55.2 ± 3.68) nmol/L, (32.72 ± 1.02) pmol/L,t =43.81,86.04 、all P ＜ 0.01 ] and the serum total triiodothyronine(TT3) and free triiodothyronine(FT3) reduction in LI group of mice[ (0.76 ± 0.08)nmol/L,(4.01 ± 0.40)pmol/L] were significantly lower than that of the control group of mice [ (1.10 ± 0.06)nmol/L,(5.40 ± 0.38)pmol/L,t =9.81,7.5 1,P ＜ 0.01 ].Iodine insufficiency strongly elevated the serum TSH in LI group of mice[ (35.67 ± 17.39)mU/L] than that in control group of mice[ (0.24 ± 0.10)mU/L,t =- 6.11,P ＜ 0.01 ].The mRNA levels of TSH β-Ⅴ in BM (9.62 ± 0.60) and in PBL( 9.25 ± 0.83 ) of LI group of mice were lower than those in control group of mice (7.69 ± 0.36,7.11 ± 0.41,t =6.77,5.64,P ＜ 0.01),while the mRNA level of TSH β-Ⅴ in pituitary of LI group of mice (1.99 ± 0.61) was increased compared with that in control group of mice (5.75 ± 0.98,t =- 8.02,P＜ 0.01).Compared with control group of mice(9.12 ± 0.62),the level of thyroid TSH β-Ⅴ mRNA in LI group of mice (9.32 ± 0.91 ) was not significantly changed (t =0.45,P ＞ 0.05).There was no detectable native TSHβ in BM,PBL and thyroid.The mRNA level of native TSHβ in pituitary in LI group of mice( - 7.17 ± 1.78) was dramatically elevated compared to that in control group of mice( - 1.43 ± 0.51,t =- 7.60,P ＜ 0.01 ).ConclusionsThe mRNA levels of TSHβ-Ⅴ are suppressed in BM and PBL in low iodinediet induced hypothyroidism mice,which suggest that immune system derived TSHβ-Ⅴ may be more important thannative TSHβ in immune-thyroid regulation.

OBJECTIVE: To determine the prevalence of depression and anxiety in patients with psoriatic arthritis (PsA), to investigate whether there is a difference in the prevalence of depression and anxiety between PsA and rheumatoid arthritis (RA) patients and to identify associated risk factors for depression and anxiety in PsA patients. METHODS: PsA and RA patients who visited Department of Rheumatology and Clinical Immunology in Peking University First Hospital from May 2018 to Sep 2019 were recruited. Self-rating anxiety scale and self-rating depression scale were surveyed and compared between PsA and RA patients. Demographics and clinical features including age, gender, disease duration, disease activity score, psoriasis area and severity index (PASI), and medical application were collected. Power Doppler and grey-scale ultrasound of joints, tenosynovitis and enthesis were performed. Multivariate Logistic regression was used to identify the factors associated with mood disorders and the odds ratio of depression and anxiety between the PsA and RA patients. RESULTS: Among the 114 enrolled PsA patients, 37 (32.5%) had mood disorders, in which 36 (31.6%) with depression and 15 (13.2%) with anxiety. Compared with 201 RA patients, PsA patients showed greater odds for depression [adjusted OR (95%CI): 2.7 (1.1-6.4)]. Depression was more often observed in the PsA than in the RA patients (31.6% vs. 18.9%, P=0.011). The similar trend for anxiety was also observed, although the difference was insignificant (13.2% vs. 8.5%, P=0.185). Age (OR=0.95, P=0.008), psoriasis duration (OR=0.94, P=0.018), pain visual analogue scale (OR=1.47, P=0.011), PASI score (OR=1.07, P=0.007) and presence of ultrasound enthesitis (OR=4.13, P=0.009) were identified as factors associated with depression in the PsA patients. PASI score (OR=1.07, P=0.001) was identified as associated factor for anxiety in the PsA patients. CONCLUSION The prevalence of depression and anxiety is elevated in PsA patients. Depression is significantly more prevalent in PsA patients than in RA patients. Younger age, shorter psoriasis duration, worse pain and presence of ultrasound enthesitis are associated with depression, while severe psoriasis rash is associated with both depression and anxiety in PsA patients.

Atropa belladonna is a medicinal plant and main commercial source of tropane alkaloids (TAs) including scopolamine and hyoscyamine, which are anticholine drugs widely used clinically. Based on the high throughput transcriptome sequencing results, the digital expression patterns of UniGenes representing 9 structural genes (ODC, ADC, AIH, CPA, SPDS, PMT, CYP80F1, H6H, TRII) involved in TAs biosynthesis were constructed, and simultaneously expression analysis of 4 released genes in NCBI (PMT, CYP80F1, H6H, TRII) for verification was performed using qPCR, as well as the TAs contents detection in 8 different tissues. Digital expression patterns results suggested that the 4 genes including ODC, ADC, AIH and CPA involved in the upstream pathway of TAs, and the 2 branch pathway genes including SPDS and TRII were found to be expressed in all the detected tissues with high expression level in secondary root. While the 3 TAs-pathway-specific genes including PMT, CYP80F1, H6H were only expressed in secondary roots and primary roots, mainly in secondary roots. The qPCR detection results of PMT, CYP80F1 and H6H were consistent with the digital expression patterns, but their expression levels in primary root were too low to be detected. The highest content of hyoscyamine was found in tender stems (3.364 mg x g(-1)), followed by tender leaves (1.526 mg x g(-1)), roots (1.598 mg x g(-1)), young fruits (1.271 mg x g(-1)) and fruit sepals (1.413 mg x g(-1)). The highest content of scopolamine was detected in fruit sepals (1.003 mg x g(-1)), then followed by tender stems (0.600 mg x g(-1)) and tender leaves (0.601 mg x g(-1)). Both old stems and old leaves had the lowest content of hyoscyamine and scopolamine. The gene expression profile and TAs accumulation indicated that TAs in Atropa belladonna were mainly biosynthesized in secondary root, and then transported and deposited in tender aerial parts. Screening Atropa belladonna secondary root transcriptome database will facilitate unveiling the unknown enzymatic reactions and the mechanisms of transcriptional control.
