Value of allergen nasal provocation test in assessment of the efficacy of house dust mites specific immunotherapy / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the value of nasal provocation test（NPT） in evaluating the efficacy of allergen immunotherapy（AIT） in patients with dust mite induced allergic rhinitis（AR）. Methods:A total of 83 patients with dust mite induced AR with/without asthma were included. Symptom score（SS）, daily medication score（DMS）, combined symptom and medication score（CSMS）, rhinoconjunctivitis quality of life questionnaire（RQLQ）, NPT and skin prick test（SPT） were assessed before and after 1 year AIT. Results:There were statistical differences in SS（P<0.000 1）, DMS（P<0.000 1）, CSMS（P<0.000 1）, and RQLQ（P<0.000 1） after 1 year of AIT compared with pre-treatment. The effective rate of CSMS was 73.49%, and the effective rate of NPT was 42.17%. CSMS was consistent with NPT in efficacy assessment（Kappa=0.437, P<0.001）; while in 54 patients with pre-treatment NPT concentrations other than the original concentration, CMSM and NPT showed better consistence（Kappa=0.895, P<0.001）. Among the 48 patients with ineffective NPT assessment in the first year, 25 patients completed the second-year follow-up, and 12 patients（48.00%） showed effective in NPT. However, 10 out of 12 patients（83.33%） with NPT concentration other than original solution pre-treatment showed effective NPT at the second year. Conclusion:NPT can be used as one of the indicators for efficacy evaluation for dust mite induced AR patients, especially for patients with positive NPT induced at lower concentrations before treatment.

HIV-1 genetic characteristics and drug resistance in newly diagnosed population in Baoding city of Hebei Province / 中华微生物学和免疫学杂志

Objective:To investigate the distribution of HIV-1 genotypes and drug resistance in newly diagnosed HIV-1 patients in Baoding in 2020.Methods:A self-developed method was used to amplify the pol gene sequence of HIV-1, and the sequencing results were analyzed by phylogenetic analysis and compared with the Stanford drug resistance database to determine the HIV-1 subtypes and gene mutations. Results:A total of 96 patients with HIV-1 infection were recruited in this study, and 83 pol gene sequences were successfully obtained. In the study population, 88 (91.7%) were male with an average age of 39 years and 54 (56.3%) were married. Most of the patients were infected through sexual contact (95.8%, 92/96), and 75.0% (72/96) were through homosexual transmission. Phylogenetic analysis showed that various HIV-1 subtypes were detected and among them, CRF01_AE (51.8%, 43/83), CRF07_BC (24.1%, 20/83) and B subtype (10.8%, 9/83) were the most epidemic strains. Moreover, the subtypes of newly identified recombinant strains in recent years accounted for 13.3% (11/83). Drug resistance test results showed that the pre-treatment drug resistance rate in newly diagnosed HIV-1 patients was 8.4% (7/83), and the drug resistance rates to protease inhibitor (PIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and integrase inhibitors (INIs) were 3.6% (3/83), 1.2% (1/83) and 3.6% (3/83), respectively. Conclusions:The HIV-1 subtypes in the newly diagnosed population in Baoding in 2020 were complex and diverse. There were many unique recombinant strains and drug-resistant strains. Therefore, it was necessary to strengthen drug resistance monitoring as well as the prevention and control of HIV-1 infection in this area.

Wuhan's experience in fighting against COVID-19:How to prevent COVID-19 infection among health care workers / 中国感染控制杂志

In the context of the coronavirus disease 2019 (COVID-19)pandemic,thousands of health care wor- kers (HCWs)worldwide infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2),some even have lost their lives.At the early stage of the epidemic,some Chinese HCWs were infected.Owing to limited knowledge of characteristics of SARS-CoV-2,more than 3,000 HCWs in Hubei Province contracted SARS-CoV-2 at the early stage of the outbreak.Due to overloaded work of HCWs in local hospitals,more than 42,000 HCWs (including HCWs from the military)were dispatched to Hubei Province from all over the country.At the peak of epidemic,one in 10 intensive care HCWs in China were working in Wuhan.During fighting against COVID-19 in China,although a certain number of HCWs were infected with SARS-CoV-2 at the early stages of the epidemic, effective prevention was achieved through timely adoption of prevention measures,including fast diagnosis,timely isolation of patients,strengthening of HCWs'safety,intensified training on basic protective knowledge and unified management of HCWs,there was no report about infection among the 42,632 members of the national medical teams sent to Hubei,and the number of COVID-19 cases among HCWs in local hospitals also significantly de- creased,thereby indicating that healthcare-associated infection (HAI)of COVID-19 among HCWs are fully pre- ventable.This paper explores how to prevent HCWs from contracting SARS-CoV-2 through effective measures during the epidemic in Wuhan,China.

How to deal with severe challenge of healthcare-associated infection due to multidrug-resistant organisms / 中国感染控制杂志

In recent years, with the widespread use of broad-spectrum antimicrobial agents, multidrug-resistant organisms (MDROs) have emerged and become more and more common, such as methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Enterobacteriaceae (CRE), which pose severe challenge to clinical anti-infective treatment and prevention and control of healthcare-associated infection. The new antimicrobial agents and bacterial resistance have developed at the same time, development of bacterial resistance seems to have a tendency to overwhelm the development of antimicrobial agents. Antimicrobial resistance (AMR) is now recognized as one of the major threat to human health worldwide. The Center for Disease Control and Prevention (CDC) of America has proposed four core plans to address the challenge of MDROs: surveillance, antimicrobial management, improvement of antimicrobial agents and diagnosis, as well as prevention and control of transmission. In response to the severe threat of MDRO infection, prevention of infection should be focused on, antimicrobial management and HAI management should be grasped at the same time and attached sufficient importance, effective measures should be taken based on the source, route, and susceptible people of infection, multiple details and constant innovation should be paid attention to, the final victory can be achieved.

Microneedle Percutaneous Drug Delivery System, Wound Repair and Pharmacology Evaluation / 中国药学杂志

Transdermal drug delivery offers a number of advantages including improved patient compliance, sustained release, avoidance of gastric irritation, as well as elimination of pre-systemic first-pass effect. However, the skin barrier function limits the transdermal penetration of macromolecular drugs. Microneedle arrays can remarkably increase the skin permeability for drugs, especially macromolecular drugs, by forming microchannels in the skin. In recent years, the types and usages of microneedle have made great progress. This review focuses on remarking the wound repair and pharmacology evaluation, as well as introduces the microneedle percutaneous drug delivery system.

Metabonomic analysis of Hugan Tablets on CCl4-induced acute hepatic injury in rats based on 1 H-NMR / 中国药理学通报

Aim To identify the potential biomarkers associated with carbon tetrachloride(CCl 4 )-induced a-cute hepatic injury in rats and explore the therapeutic effect of Hugan Tablets(HGT). Methods The model was established by intraperitoneal injection of CCl4 in oil(1 : 1,V/ V)with a dosage of 1 mL·kg - 1 body weight to rats once. The levels of aspartate aminotrans-ferase(AST),alanine aminotransferase(ALT),alka-line phosphatase (ALP ) and lactate dehydrogenase (LDH)in serum of rats were determined. Moreover,a proton nuclear magnetic resonance (1 H-NMR)based metabonomic approach in combination with multivariate data analysis was applied to demonstrate CCl4-induced acute hepatic injury metabolic perturbations in rat urine and feces and identify the corresponding metabolic bio-markers. The intervention effect of HGT was evaluated based on the changes of metabolic phenotype and po-tential biomarkers related to acute hepatic injury. Re-sults The levels of AST,ALT,ALP and LDH in ser-um of rats with acute hepatic injury were significantly reduced by administration of HGT,respectively. The disturbed metabolic state associated with CCl4-induced acute hepatic injury in rat urine and feces could be re-stored by HGT. Meanwhile,five potential biomarkers (2-oxoglutarate,citrate,creatinine,trimethylamine N-oxide,hippurate)in rat urine and three potential bio-markers(butyrate,glucose,uracil)in rat feces related to acute hepatic injury were reversed by administration of HGT,respectively. Conclusion HGT exerts pro-tective effects against CCl4-induced acute hepatic inju-ry in rats,which is probably mediated by regulation of tricarboxylic acid cycle and gut microbiota metabolism.

Clinical features of ocular symptom in patients with allergic rhinitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the clinical characteristics of ocular symptoms in patients with allergic rhinitis (AR) and the impact of the ocular symptoms on patients' quality of life.@*METHOD@#AR patients' history and clinical data were collected and analyzed. One hundred cases were extracted from adult patients with and without ocular symptoms in each group and their quality of life were evaluated using rhino-conjunctivitis quality of life questionnaire (RQLQ).@*RESULT@#Totally 1119 cases were collected and 859 cases had ocular symptoms. Of the patients with ocular symptoms, 582 cases were mild, 234 cases were moderate, 43 cases were severe. Eye itching was the most common symptom, followed by tears, hyperemia and swelling. Patients with ocular symptoms had longer disease history than non ocular symptom group (P < 0.05). There was a positive correlation between ocular and nasal symptoms (P < 0.01); patients with ocular symptoms had more severe nasal symptoms than patients without ocular problems; while patients with moderate to severe AR had more severe ocular symptoms than mild AR patients (P < 0.01). Female patients had higher incidence (P < 0.05) and ocular symptoms score (P < 0.05) than male. Children less than 10 years old had a relative lower incidence and score of ocular symptoms. While the incidence and score had an increasing trend for patients older than fifty. There was no difference regarding the type and number of allergen in the patients with and without ocular symptom. Moreover, patients with ocular symptoms had higher scores in the domains of non-nose/eye symptoms, practical problems, ocular symptoms, emotional function and total score in RQLQ than patients without ocular symptom.@*CONCLUSION@#It was common for the AR patients to have ocular symptoms, and ocular symptoms had obvious influence on the patients' quality of life. So controlling of the ocular symptoms should not be ignored during the diagnosis and treatment of AR.
