RESUMO
PURPOSE: This study aimed to describe a peripherally inserted central catheterisation (PICC) for paediatric patients with inaccessible access and a high risk of general anaesthesia (GA). METHODS: This was a retrospective observational study involving all paediatric inpatients who performed the PICC via an EJV approach without GA between September 2014 and September 2021 in a provincial key clinical speciality. RESULTS: A total of 290 EJV line placement attempts were performed, and 29 were excluded due to missing placement results, resulting in a sample size of 261. The anatomical localisation, punctures, and catheterisation success rates for this practice were 100%, 100%, and 90.04%, respectively. The placement success rate in children younger than one year was 93.75% (45/48). The median line duration of use was 19 days, with a median length of catheter insertion of 13 cm. The most common complications were catheter malposition (n = 20) and dislodgement (n = 7). CONCLUSION: The PICC via an EJV approach without GA is a feasible and safe practice with acceptable success and complication rates, and low costs. It might be an attractive alternative for obtaining central vascular access for paediatric patients.

OBJECTIVE: To determine the capability of alveolar fluid clearance and the changes of sodium channel in alveolar type II cells (ATII) in oleic acid-induced acute lung injury. METHODS: Forty four male Sprague-Dawley (SD) rats were randomized into a control group and an acute lung injury (ALI) group, with 22 rats in each group. The ALI model was established by oleic acid. The ATII cells were acutely isolated and purified, and the ATII cellular ultrastructure was observed by transmission electron microscope. In each group, the mRNA expression of 3 epithelial sodium channel (ENaC) subunits in acute isolated ATII cells from 8 rats were detected by reverse transcription-polymerase chain reaction (RT-PCR), while the extravascular lung water (EVLW) content was quantified in 7 rats by gravimetric measurement, and the lung histopathological changes were studies in 7 rats. RESULTS: In the ALI group, Smith lung injury score (7.6 +/- 0.8) and EVLW (0.80 +/- 0.17) ml were significantly higher than those in the control group [Smith score: (1.1 +/- 0.2), t = -20.859, P < 0.01; EVLW: (0.52 +/- 0.10) ml, t = -3.851, P < 0.01]. The transmission electron microscopic observation showed that there were degeneration, apoptosis, and lamellar body vacuolar changes in the ATII cells from the ALI rats. RT-PCR demonstrated that the alpha-subunit of the ENaC mRNA expression was the highest among the 3 subunits (F = 4.40, P = 0.02). In the ALI group, mRNA expressions of all the 3 ENaC subunits in acutely isolated ATII cells were decreased as compared to those in the control group [alpha-subunit: (51 +/- 9)% vs (82 +/- 7)%, t = 7.61, P < 0.01; beta-subunit: (13 +/- 7)% vs (25 +/- 4)%, t = 4.53, P < 0.01; gamma-subunit: (31 +/- 15)% vs (40 +/- 17)%, t = 3.01, P < 0.05; respectively]. CONCLUSIONS: The capacity of alveolar fluid clearance was attenuated in oleic acid-induced acute lung injury. The ENaC subunit mRNA levels of ATII cells were significantly decreased in ALI rats.

OBJECTIVE: To investigate the effects of co-exposure to hyperthermia and lipopolysaccharides (LPS) on tumor necrosis factor-alpha (TNF-alpha) expression in the lungs and small intestines of rats. METHODS: Male pathogen-free Wistar rats were randomly assigned into saline-injected normothermic control (C), saline heat exposure (H), LPS normothermic control (L), and LPS plus heat exposure (HL) groups. The rats in H and HL groups were exposed in a chamber at an ambient dry bulb temperature (Tdb) of 35.0-/+0.5 degrees celsius;, and those in C and L groups to 26-/+0.5 degrees celsius;. In L and HL groups, the rats were given an intravenous injection of LPS 10 mg/kg via the tail vein to induce endotoxemia, and those in C and H group received 10 ml/kg injection. The plasma levels of sTNFrI and sTNFrII were detected at different time points using ELISA. The expression of TNF-alpha in the lungs and small intestines was detected by immunohistochemical SABC method, and the damage of the lungs and small intestines evaluated histologically 120 min after the treatment. RESULTS: Co-exposure to hyperthermia and LPS caused significantly enhanced expressions of TNF-alpha and its receptor sTNFrI and sTNFrII in the plasma and tissues and obvious histopathological damage in the lung and small intestines. CONCLUSION: Co-stress of hyperthermia and LPS-induced toxicity is associated with the expression of TNF-alpha in the lung and small intestines.

OBJECTIVE: To improve the diagnosis and treatment of abdominal injury. METHODS: The clinical data of 286 patients with gastrointestinal tract laceration admitted between 2004 and 2009 to our hospital was analyzed. RESULTS: The duration after trauma was 15 min to 2 days. Of the 286 patients eventually confirmed by laparotomy, 273 were cured, 3 showed improvement and 10 died. CONCLUSION: Abdominal trauma in patients with gastrointestinal tract laceration, Abdominal puncture diagnosis and orthostatic abdominal X-ray are rapid and effective diagnostic methods for gastrointestinal tract laceration in patients with abdominal trauma. Laparotomy is the primary treatment measures and should be performed as early as possible.

OBJECTIVE: To study the application of intraoperative irrigation of the colon in primary resection and anastomosis of left colorectal cancer with intestinal obstruction. METHODS: The clinical data were analyzed in 58 patients with left colon rectal cancer and intestinal obstruction undergoing intraoperative irrigation of the colon for primary anastomosis, and the results were compared with 58 patients receiving conventional primary tumor resection. RESULTS: The mean intraoperative blood loss or postoperative hospital stay was comparable between the two groups, but the patients undergoing colon irrigation had significantly delays in the recovery of bowel movement. CONCLUSION: With strict control of the surgery indication, intraoperative colon irrigation can be safe and feasible in primary resection and anastomosis of left colorectal cancer with intestinal obstruction.

OBJECTIVE: To observe the therapeutic effect of traditional Chinese medicine (TCM) and Western medicine (WM) treatments on mycoplasmal pneumonia in children and the changes in the serum cytokines. METHODS: Ninety children with mycoplasmal pneumonia were randomly divided into the treatment group and the control group. TCM was given orally and azithromycin at the daily dose of 10 mg/kg was administered intravenously in the treatment group. In the control group, only intravenous azithromycin was given. After a 7-day treatment, the response rate, time of symptom disappearance, and serum levels of IL-6, IL-8 and TNF-alpha were observed. RESULTS: The total response rate was 93.33% in the treatment group and 73.33% in the control group, showing a significantly better therapeutic effect in the treatment group (P<0.05). The combined treatments also showed better effects in alleviating fever, coughing and rales (P<0.05), and resulted in more obvious reduction in the serum levels of cytokines (P<0.05). CONCLUSION: Combined treatment with TCM and WM produce good therapeutic effects in children with mycoplasmal pneumonia.

OBJECTIVE: To investigate the epithelial sodium channel (ENaC) subunit mRNA expression in acutely isolated rat alveolar type II (ATII) cells. METHODS: Acutely isolated ATII cells from 20 SD rats were purified and ENaC alpha, beta, gamma-subunit mRNA levels were determined by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: mRNA expressions of all the subunits were detected in the ATII cells, and ENaC alpha-subunit mRNA showed significantly higher expression than beta- and gamma-subunit mRNAs, and the expressions of the latter two mRNAs were comparable. CONCLUSION: As the predominant ENaC subunit expressed at the mRNA level in rat ATII cells, the alpha-subunit of ENAC plays an important role in alveolar fluid clearance.
