ABSTRACT
Objective:To investigate the clinical characteristics and pathogen spectrum of acquired immunodeficiency syndrome (AIDS) patients complicated with pulmonary filamentous fungal infection in Guangdong Province, so as to provide evidences for improving the diagnosis and treatment.Methods:A total of 143 AIDS patients with pulmonary filamentous fungal infection hospitalized in Guangzhou Eighth People′s Hospital, Guangzhou Medical University from January 2016 to December 2018 were included. The filamentous fungi cultured in bronchoalveolar lavage fluid of these patients were identified with morphological and molecular biological methods. And their clinical characteristics were analyzed. Nonparametric Kruskal-Wallis H test and chi-square test were used for statistical analysis. Results:Among the 143 patients, 116(81.1%) had fever, 104(72.7%) had cough, 83(58.0%) had expectoration, and 59(41.3%) had anhelation. The CD4 + T lymphocyte count was 22.0(9.3, 60.8) cells/μL and 118(82.5%) cases were below 100.0 cells/μL. The white blood cell counts decreased in 52(36.4%) cases and increased in 18(12.6%) cases, anemia was found in 109(76.2%) cases, platelet count decreased in 29(20.3%) cases. Sixty-four (44.8%) cases were positive for galactomannan test. Chest computed tomography showed diffuse infection of both lungs in 114(79.7%) cases, miliary changes in 12(8.4%) cases, pleural effusion in 44(30.8%) cases, and enlargement of pleural and (or) mediastinal lymph nodes in 45(31.5%) cases. After receiving antifungal therapy, 124 (86.7%) cases were cured or improved, and 19 (13.3%) cases were discharged automatically or died of disease deterioration. Among the 143 strains of filamentous fungi, there were 56 strains of Aspergillus species pluralis (39.2%, including 24 strains of Aspergillus fumigatus), 37 strains of Talaromyces marneffei ( T. marneffei) (25.9%), 22 strains of Penicilium species pluralis (15.4%), and 28 strains of other genera of filamentous fungi (19.6%). The median CD4 + T lymphocyte counts in patients infected with Aspergillus species pluralis, T. marneffei, Penicilium species pluralis and other genera were 24.5, 15.0, 53.5 and 22.0 cells/μL, respectively, and the difference was statistically significant ( H=11.282, P=0.010). The proportions of AIDS patients with different pulmonary filamentous fungal infection of CD4 + T lymphocyte count ≤50.0 cells/μL in descending order were T. marneffei group (89.2%(33/37)), Aspergillus species pluralis group and other genera group (67.9%(38/56), 67.9%(19/28)), and Penicillium species pluralis group (54.5%(12/22)), and the difference was statistically significant ( χ2=9.296, P=0.026). Conclusions:The clinical manifestations of pulmonary filamentous fungal infection in AIDS patients in Guangdong Province are not specific. The pathogenic spectrum contains various genera, and T. marneffei and Aspergillus fumigatus are dominant, which could be correlated with CD4 + T lymphocyte count.
ABSTRACT
Objective To explore the clinical effect of holistic nursing in the operation room for surgical children patients. Methods 120 patients required surgical treatment were selected and divided into the control group(45 cases)and the observation group(75 cases)randomly.The control group was given routine nursing,the observation group was given holistic nursing including preoperative interview,psychological care and all the preparations,strict check upon going into the operation room and before surgery,to help children keep graceful position,to cooperate closely with the anesthetist and surgeon,to observe the condition of patients and give good infusion management,to give continued observation of the disease condition after surgery,to make children safe escort back to the ward,and to make transfer with ward nurses.The treatment effect was compared between two groups. Results Two groups of children passed the period of operation and anesthesia safely,without appearing accidental situation.The satisfaction degree of the observation group was significantly higher than the control group.One case appeared operation accident and two cases appeared anesthesia awareness in the control group,and they were correctly handled.No one appeared operation accident and anesthesia awareness in the observation group.The differences between the two groups were significant. Conclusions Application of holistic nursing in the operation room for children patients puts forward higher requirements for nurses.It can help children cooperate with surgery better to achieve better surgical results,which is worthy of promotion.
ABSTRACT
Objective To study the effects of purified rabies vaccine for human use (RV) on specific Th1/Th2 cytokines in human. Methods Twenty cases were injected intramuscularly with 5 full doses of RV. PBMCs were isolated from the blood sample collected at day 0, 14, 45 after the RV inoculation. Neutralizing antibody was determined by ELISA, and the proliferation of lymphocyte by in vitro test. The levels of RV specific IFN-γ, TNF, IL-2,IL-4, IL-5, IL-10 in the culture supernatants were detected by cytometric bead array (CBA). Results The neutralizing antibody was tested positive in 19 cases 45 days after inoculation and 1 case after 60 days, with the positive rate reaching 100%. After stimulation with RV, the lymphocyte transformation index at day 14, 45 in cases were significantly higher than those day of 0 (P< 0.05), and similar results were confirmed with IFN-γ, IL-2, IL-4, IL-5 tested by CBA (P<0.05). Condusion The RV could induce humoral and antigen-specific cellular immune responses in human, tested by showing good protective effect on rabies virus.
