Aim To investigate the potential role of desipramine(DP) on lipoplysaccharide(LPS)-induced acute lung injury(ALI)and the mechanism of its action.Methods Kunming mice were divided into four groups randomly:NS group(NS),DP control group(DP),LPS group(LPS)and DP treatment group(DP+LPS).The model of ALI in mice was induced by lipoplysaccharidel(LPS,10 mg·kg~(-1),ip).Six hours after LPS challenged,the lung samples were taken for determination of lung wet-to-dry weight ratio(W/D),myeloperoxidase(MPO)activity,and malondialdehyde(MDA)content.The bronchoalveolar lavage fluid(BALF)samples were analyzed for total protein concentrateion and white blood cell(WBC)count.The levels of tumor necrosis factor-α(TNF-α)in lung were measured by ELISA.Results LPS could significantly increase the total protein concentration and WBC number in BALF.The lung W/D ration,MPO activity,MDA content and the levels of TNF-α in lungs all increased after ip injection of LPS.Pretreatment with DP decreased all the changes induced by the LPS.Conclusion Pretreatment with DP protects lung from LPS-induced lung injury in mice,which is,at least in part,through inhibiting the level of TNF-α and decreasing the sequestration of neutrophils and lipid peroxidation.

Objective:To investigate the association between age and cardiac tamponade after radiofrequency ablation of atrial fibrillation(RAAF).Methods:Clinical data of patients undergone de novo AF ablation procedures at Beijing Anzhen Hospital from January 2013 to December 2016 were retrospectively collected.Patients were divided into an elderly group(age ≥60 years)and a non-elderly group(age <60 years). Logistic regression analyses were used to evaluate the association between old age and the risk of cardiac tamponade complicating RAAF.Results:A total of 5 313 patients were involved in this study, including 41 patients(0.77%)with cardiac tamponade.The proportion of cardiac tamponade was higher in the elderly group than in the non-elderly group(1.1% or 32/2 950 vs.0.4% or 9/2 363, χ2=8.489, P=0.004). One patient with cardiac tamponade in the elderly group required immediate surgical repair whereas none in the non-elderly group did.No patient died in hospital.Multivariate Logistic regression analysis showed that the risk of cardiac tamponade increased in the elderly group, compared with the non-elderly group( OR=2.570, 95% CI: 1.190-5.570, P=0.017). Stratified analysis revealed that among females and patients with oral anticoagulants, left atrium dimension < 40 mm or procedure duration≥ 120 min in the elderly group carried a higher risk of cardiac tamponade than those in the non-elderly group( OR=1.011, 2.914, 3.922 and 3.244, P<0.05). Conclusions:Old age(age ≥60 years)is an independent risk factor for cardiac tamponade complicating RAAF.

Objective Prognostic value of cardiac troponin T,echocardiography and ECG in patients with confirmed pulmonary embolism were evaluated. Methods 105 consecutive patients with confirmed PE were enrolled in this retrospective study. PE was confirmed by pulmonary angiography,lung scan or echocardiography and subsidiary analyses, cTnT was measured within 24 hours after admission. ECG and ECHO were recorded within 24 hours after admission. Results ECG signs of acute right ventricular strain are not predictors of mortality and severe complications in patients with confirmed PE. Only right ventricular dilation but not pulmonary hypertension detected at echocardiography in patients with acute PE is an independent risk factor for fatal outcome. There were significant differences in right ventricular dysfunction,massive PE and severe complications between the troponin-positive group and the troponin-negative group. In logistic regression analysis,cTnT is an independent predictor of severe complications. Furthermore,high cTnT was significantly associated with severe PE. Conclusion Right ventricular function is an important prognostic factor for pulmonary embolism. Echocardiographically detected right ventricular dysfunction can be used to assess the prognosis of PE. Elevation of cTnT was significantly associated with right ventricular dysfunction,and can be used to assess the prognosis of PE. ECG signs of acute right ventricular strain were not specific, so can not be used to assess the prognosis of PE.

ObjectiveTo investigate the predisposing factors and pathogenic fungal species of Malassezia folliculitis in different geographical areas and body sites.MethodsTotally,241 patients diagnosed with Malassezia folliculitis were asked to complete a questionnaire.The content of hair follicles was obtained and subjected to fungal smear and culture examination.Fungal species were identified according to morphological,physiological and biochemical features.Results Of the 241 patients with Malassezia folliculitis,204 (84.65%) were positive for smear examination.A total of 259 specimens were collected from these patients,and fungal culture grew 213(82.24%) strains,of which,209 belonged to Malassezia species,4(1.54%) to Candida species.Among the 209 Malassezia strains,186 were activated and subjected to species identification which resulted in 6 species,including M.furfur (111 strains,59.68% ),M.sloofiae (43 strains,23.12% ),M.sympodialis (17 strains,9.14%),M.globosa (9 strains,4.84%),M.pachydermatis (4 strains,2.15%),and M.obtuse(2 strains,1.08% ).Of the pathogenic fungi of Malassezia folliculitis,M.furfur predominated in the chest,back,abdomen,face and neck,M.sloofiae in the upper limbs,shoulders and vertex,M.globosa in the lower limbs.There were obvious differences in the distribution of pathogenic fungal species at different body sites in a same host,and M.furfur with M.sloofiae or M.sympodialis appeared to be the most common pathogens.ConclusionsIn this study,6 Malassezia species are identified in patients with Malassezia folliculitis in Nantong and Nanjing area,M.furfur and M.sloofiae appear to be the dominant pathogens.
8. Research progress of tenofovir alafenamide in blocking mother-to-child transmission of hepatitis B virus
Chinese Journal of Clinical Pharmacology and Therapeutics 2023;28(5):578-582
Hepatitis B virus (HBV) infection is a global public health problem, and the prevention of mother-to-child transmission (MTCT) is an important intervention method. As a new nucleoside reverse transcriptase inhibitor, tenofovir alafenamide (TAF) has the characteristics of strong liver targeting and low peripheral blood exposure. Although it has been used in the treatment of chronic hepatitis B widely, its application in blocking mother-to-child transmission of HBV is still limited. This paper reviews the characteristics of TAF, the effects of TAF on infants and pregnant women, in order to provide new ideas for the prevention of mother-to-child transmission of HBV.

OBJECTIVETo establish the differential templates of the skeletal profiles for Shanghainese with normal occlusion in early permanent dentition.
METHODS71 lateral cephalometric radiographs of subjects with normal occlusion in early permanent dentition, aged from 11 - 15 years (37 females and 34 males) were traced. 23 skeletal landmarks were identified on the tracings, which afterwards were scanned on the computer. An x-y coordinate system was established: the tracing superimposed on sella rotated 7 degrees down from the sella-nasion line as the x axis and the vertical line through sella perpendicular to the x axis as the y axis. A special length/depth ratio was designed. The length/depth ratio of each graph were calculated. Steiner analysis was applied to check the difference between genders.
RESULTSThere was no difference between genders. The tracings were divided into three categories: short face, normal face and long face according to the mean and standard deviation of the ratio. The three types of tracings were superimposed on the x axis with sella registered. Three templates were created.
CONCLUSIONSThe differences were apparent when the three templates were superimposed.
