Abstract: Objective To explore the clinical data of children with Talaromyces marneffei (TM) infection admitted to the pediatric intensive care unit (PICU) to improve the diagnosis and treatment of TM infection in children. Methods The clinical data of 23 children with TM infection treated in four PICUs in southern China from January 2013 to December 2022 were retrospectively analyzed, including clinical characteristics, laboratory tests, treatment regimens, and outcomes. Results Among the 23 children, there were 14 boys and 9 girls, with a median age of 24 months. The time from onset to admission was 15 (range 10-30) days, and one patient had immunodeficiency disease. Common symptoms included fever (91.3%, 21 cases), cough (78.3%, 18 cases), and hepatosplenomegaly (78.3%, 18 cases). Severe clinical complications included multiorgan dysfunction (69.6%, 16 cases), septic shock (65.2%, 15 cases), and acute respiratory distress syndrome (65.2%, 15 cases). All patients elevated CRP levels, and 69.2% (9/13) had a positive G test. Elevated IgE levels were observed in 53.3% (8/15) cases, CD4/CD8 inversion in 17.6% (3/17) cases, and reduced NK cells in 84.2% (16/19) cases. HIV tests were negative in all cases. TM was most frequently detected by blood and bone marrow cultures. Seven cases were diagnosed with immunodeficiency by genetic testing. With monotherapy or combination of amphotericin B or/and voriconazole, followed by oral medication, 13 (56.5%) children died. Conclusions TM infection is clinically atypical in HIV-negative children, and patients admitted to PICU have rapidly deteriorated, with severe complications and a high mortality rate. Early use of multiple samples, and multiple methods to detect TM, combined with immune function and genetic test, is helpful to early diagnosis. The antifungal treatment strategies still need further study.

Objective To observe the effects of laparoscopy combined with choledochoscopy in the treatment of polypoid lesions of gallbladder and the effects on postoperative rehabilitation of patients. Methods 78 cases of patients with polypoid lesions of gallbladder treated in our hospital from August 2011 to November 2014 were selected as the study object. According to the order of medical treatment and hospital admission , the patients were numbered and randomly divided into laparoscopy group and combined group , with 39 cases in each group. The laparoscopy group were treated by laparoscopic cholecystectomy while the combined group were treated by laparoscopy combined with choledochoscopy gallbladder-protection surgery. The operation indicators , recovery of gastrointestinal function and incidence of postoperative complications in the two groups were observed. After discharge , the 2 groups of patients were followed up for 1 year. The improvement of postoperative digestive tract symptoms and rehabilitation of patients was observed. Results The intraoperative bleeding volume, postoperative fasting time, defecation time and hospitalization time of the combined group [(20.13 ± 7.48) mL, (0.51 ± 0.98) d, (1.20 ± 0.84) d, (1.98 ± 1.54)d] were less than those of the laparoscopy group (P <0.05); The incidence rate of complications in the combined group (10.26%) was lower than that in the laparoscopy group (33.33%) (P < 0.05); Immediately at the end of operation and 1 week after operation, VAS scores of the combined group [(4.23 ± 0.41), (2.46 ± 0.17) ] were lower than those in the laparoscopy group (P < 0.05); At the last follow-up, KPS score of the combined group increased to (89.98 ± 1.24), which was higher than that in the laparoscopy group (P < 0.05); GradeⅠpostoperative recovery in the combined group accounted for 87.18% which was higher than that in the laparoscopy group (64.10%). There was no case of grade III and the proportion was lower than that in the laparoscopy group (15.38%). The differences in proportions of grade I and III between the two groups were statistically significant (P < 0.05). Conclusion To adopt laparoscopy combined with choledochoscopy in the treatment of polypoid lesions of gallbladder , the curative effect is certain and the minimally invasive advantage is obvious. The long-term recovery effect is good and the safety is high.

Objective To investigate the clinical therapeutic effect of acupuncture on pulmonary infection after acute cerebral infarction.Methods Seventy patients with pulmonary infection after acute cerebral infarction were randomly allocated to treatment and control groups, 35 cases each. The control group received routine medication and the treatment group, acupuncture in addition. Pre-treatment and post-treatment National Institutes of Health Stroke Scale (NIHSS) scores and clinical pulmonary infection scores (CPIS) were compared between the two groups. The correlation between the NIHSS score and the CPIS score was observed.Results There were statistically significant pre-/post-treatment differences in the NIHSS score and the CPIS score in the two groups (P<0.05,P<0.01). There were statistically significant post-treatment differences in the NIHSS score and the CPIS score between the treatment and control groups (P<0.05). The correlation between the NIHSS score and the CPIS score was low in the treatment group after treatment (r=0.417,P<0.05).Conclusions Acupuncture plus medication is an effective way to treat pulmonary infection after acute cerebral infarction. It can improve the NIHSS score and the CPIS score in the patients.

Objective To evaluate the performance of trilobed flaps for reconstruction of nasal tip defects. Methods Totally, 23 patients with nasal tip defects after tumor resection were enrolled into this study. Skin defects varied from 1.5 cm × 1.5 cm to 2.5 cm × 2.5 cm in size. According to the location and size of skin defects, trilobed flaps were designed, and the angle between two lobes ranged from 45° to 50°. The size of the first lobe was approximately equal to that of the skin defect, while the size of the second and third lobes decreased successively. During flap design, the integrity of nasal subunits was sufficiently considered, and the incision lines were placed along the boundary lines of the nasal subunit as far as possible, so as to conceal the incision scar with natural skin folds. Results After the operation, skin flaps survived with primary healing of incisions in all the patients. After 6 - 24 months of follow up, the color, texture and thickness of flaps were similar to those of their surrounding skin, and incision scars were inconspicuous. No malformation occurred in the nasal ala, nostril, nasal columella or surrounding organs, and satisfactory nasal appearance and function were achieved. Conclusion Trilobed flaps can be used to effectively repair relatively large skin defects of the nasal tip with satisfactory nasal appearance and function.
