Objective To investigate the clinical parameters,risk factors,treatment and clinical outcomes of pneumocystis pneumonia(PCP) in children without human immunodeficiency virus(HIV). Methods Retrospective a-nalysis was made for the clinical features,risk factors,treatment and prognoses of the non-HIV infected severe PCP pa-tients hospitalized at Pediatric Intensive Care Unit( PICU) of Children′s Hospital Affiliated to Capital Institute of Pedi-atrics. Results During April of 2010 to April of 2014,there were 10 cases of non-HIV infected severe PCP in PICU of Children′s Hospital Affiliated to Capital Institute of Pediatrics. All of the patients had predisposing diseases,in which 3 cases had connective tissue diseases,2 cases had acute leukemia,3 cases had severe pneumonia and 2 cases had con-genital immunodeficiency. The main clinical manifestations of those 10 patients were fever, cough, tachypnea and obvious dyspnea. All patients developed respiratory failure. The median value of Pediatric Critical Illness Score was 79. The median arterial oxygen pressure was 58 mmHg(1 mmHg=0. 133 kPa). The median oxygenation index was 103 mmHg. The median alveolo-arterial oxygen partial pressure difference was 43. 8 mmHg. The median CD4+T-lympho-cytes counts was 169 ×106/L. Eight patients on admission had mixed infection. Acute respiratory distress syndrome (ARDS) occurred in all of the patients,and 7 cases of them had multiple organ dysfunctions. All of the patients re-quired ventilation support. The median day for invasive mechanical ventilation days was 11 and the median day for non-invasive ventilation days was 6. The pneumothorax occurred in 5 patients. All patients received trimethoprim-Sulfame-thoxazole as initial therapy and Caspofungin treatment in combination in 7 cases of the patients. Six patients had nosoco-mial infection. The median time of PICU stay was 15. 5 days. Six patients survived and the mortality was 40%(4/10 cases) . Conclusions PCP is a kind of fatal diseases which occurred in patients with immunocompromised conditions and concurrent ARDS or multiple organ dysfunctions. Diagnostic suspicion and mechanical ventilation therapy with lung protective ventilation strategies may improve the clinical outcomes of non-HIV-infected PCP in children.

This study examined the value of volume rendering (VR) interpretation in assessing the growth of pulmonary nodular ground-glass opacity (nGGO). A total of 47 nGGOs (average size, 9.5 mm; range, 5.7-20.6 mm) were observed by CT scanning at different time under identical parameter settings. The growth of nGGO was analyzed by three radiologists by comparing the thin slice (TS) CT images of initial and repeat scans with side-by-side cine mode. One week later synchronized VR images of the two scans were compared by side-by-side cine mode to evaluate the nGGO growth. The nodule growth was rated on a 5-degree scale: notable growth, slight growth, dubious growth, stagnant growth, shrinkage. Growth standard was defined as: Density increase ≥ 30 HU and (or) diameter increase (by 20% in nodules ≥10 mm, 30% in nodules of 5-9 mm). Receiver operating characteristic (ROC) was performed. The results showed that 32 nGGOs met the growth criteria (29 nGGOs showed an increase in density; 1 nGGO showed an increase in diameter; 2 nGGOs showed an increase in both diameter and density). Area under ROC curve revealed that the performance with VR interpretation was better than that with TS interpretation (P<0.01, P<0.05 and P<0.05 for observers A, B and C respectively). Consistency between different observers was excellent with both VR interpretation (κ=0.89 for observers A&C, A&B, B&C) and TS interpretation (κ=0.71 for A&B, κ=0.68 for A&C, κ= 0.74 for B&C), but time spending was less with VR interpretation than with TS interpretation (P<0.0001, P<0.0001 and P<0.05 for observers A, B and C, respectively). It was concluded that VR is a useful technique for evaluating the growth of nGGO.

Objective To observe the formation of the biofilm in endotracheal tubes,the characteris-tics of etiology, drug resistance and relationship between the biofilm and ventilator-associated pneumonia ( VAP) . Methods A total of 60 cases of ventilated children patients whose mechanical ventilation time were≥48 h in the ICU from September 2010 to September 2012,according to the mechanical ventilation time,all cases were divided into 2 to 6 d group,7 to 14 d group and ≥15 d group. The incidence of VAP, biofilm structure under the electron microscope,etiology culture positive rate of the lower airway secretions and bio-film,etiological characteristics and drug resistance were prospectively studied. Results ( 1 ) A total of 19 cases occurred VAP in 60 cases of mechanical ventilation,the incidence of VAP was 31. 7%. (2) Observed by electron microscope,biofilm had formed in the endotracheal tube inner wall in early period of mechanical ventilation. With prolonged mechanical ventilation,biofilm structure had improved,as well as VAP incidence rate from 9. 1%(2 to 6 d group ) increased to 44. 4%(7 to 14 d group) and 88. 9%(≥15 d group). (3) A large number of pathogenic bacteria colonized in the biofilm. Gram-negative bacilli were dominate and drug resistance was high. (4) With prolonged mechanical ventilation,the cultured pathogens from the lower airway secretions and biofilm converged. Conclusion Biofilm could form in the endotracheal tube with mechanical ventilation patients,and is associated with the occurrence of VAP and refractory infections.

Objective:To explore the risk factors of hypopituitorism after aneurysmal subarachnoid haemorrhage (aSAH) in the acute phase and analysis the effect of hypopituitorism on prognosis.Methods:Patients with aSAH that were diagnosed and treated in China-Japan Union Hospital from Sep. 2017 to Sep. 2018 and undergoing pituitary function evaluation within 3 to 7 days were retrospectively analyzed. 72 patients were enrolled, including 31 males and 41 females. The average age was 50.1 years old (36-71) . The WFNS gradings were Ⅰ, 24; Ⅱ, 20; Ⅲ, 15; Ⅳ, 10; Ⅴ, 3. The Fisher gradings were 2, 21; 3, 38; 4, 13. Acute hydrocephalus happened in 13 cases. Aneurysm located in the Willis circle in 56 cases and not in the Willis circle in 16 cases. 37 cases were treated by microsurgical clipped and 35 cases were treated by embolism. Patients with hypocortisolism were treated by hydrocortisone replacement, and patients with hypothyroidism were given levothyroxine replacement therapy. Patients were followed up at 3 months and their recovery was evaluated by GOS score.Results:Hypopituitorism was detected in 34 patients; the incidence of hypopituitorism was 47.2%. There was no significant correlation between the occurrence of hypopituitorism and age, gender, and hydrocephalus ( P>0.05) . Patients with WFNS grade ≥Ⅳ, Fisher grade 4, aneurysm located in the Willis circle, and treated by clipping were more likely to undergo hypopituitorism. The proportion of patients with good recovery (GOS ≥4) in the hypopituitorism group was smaller than that in the normal pituitary function group at the 3-month follow-up. Conclusions:Patients with WFNS grade ≥Ⅳ, Fisher grade 4, aneurysm located in the Willis circle, and treated by clipping are more likely to undergo hypopituitorism. Hypopituitorism in acute stage affects the prognosis of aSAH patients. Patients with hypocortisolism and hypothyroidism should be treated actively.

OBJECTIVETo study the impact of neoadjuvant radiochemotherapy on erectile and urinary functions in mid-low rectal cancer patients.
METHODSSeventy mid-low rectal cancer patients from January 2012 to May 2013 in The Sixth Affiliated Hospital, Sun Yat-sen University were prospectively enrolled. According to tumor staging and patient decision, patients received neoadjuvant radiochemotherapy(50 Grays administered over a six-week period and four cycles of concomitant mFOLFOX6 chemotherapy followed by operation (study group) or surgery alone(control group). Dropouts, loss to follow up and relapse during follow-up were removed from the analysis. A total of 30 patients stayed in study group and 29 patients in control group. To assess erectile and urination functions, the five-item version of the international index of erectile function (IIEF-5) and the international prostate symptom score (IPSS) questionnaires were used before therapy and 12 months after surgery.
RESULTSIn both study and control groups, total IIEF-5 score was decreased significantly at postoperative 12-month compared to initial assessment(P<0.01). Compared with control group, IIEF-5 score change was significantly higher in study group (9.6 ± 6.1 vs. 5.3 ± 5.3; P<0.01). Total IPSS score in both groups was increased significantly at postoperative 12-month compared to initial assessment(P<0.05). No significant difference was found in IPSS score change between the two groups (3.0 ± 3.4 vs. 1.5 ± 3.0, P>0.05). Univariate analysis on study group showed that age, tumor location and maximal diameter were associated with erectile dysfunction. Age was associated with urination dysfunction (all P<0.05).
CONCLUSIONNeoadjuvant radiochemotherapy has significant impact on erectile dysfunction after surgery in mid-low rectal cancer patients.
