This experimental study was intended to find the possibility of using PDLLA as scaffolds in tissue engineering and to assess the effect of PDLLA scaffolds with different porosity on chondrocytes. Chondrocytes were cultured when they were seeded onto PDLLA scaffolds with different porosity. Under scanning electron microscope, the scaffolds in hydrophila and adsorptivity to chondrocytes and the function of the cells were observed. The chondrocytes were noted to proliferate on PDLLA scaffolds with different porosity, those with 90%-96% porosity being significantly better. So PDLLA can be used as a scaffold in tissue engineering, and the proper porosity of PDLLA scaffolds should be 90% approximately 96%.

Objective To evaluate the clinical efficacy of anterior single segmental decompression and instrumentation through Endoring self-support retractor-assisted minimally invasive small incision approach in the treatment of Denis type B thoracolumbar burst fractures.Methods A retrospective case series study was made on 26 cases (14 males and 12 females,mean age of 48.5 years) of Denis type B thoracolumbar burst fractures treated by anterior single segmental decompression and instrumentation through Endoring self-support retractor-assisted minimally invasive small incision approach from January 2007 to June 2009.Age was 18-68 years (mean,48.5 years).The fractured vertebrae included T1 in three cases,L1 in 18 and L2 in five.The neurological status was Grade C in eight cases,Grade D in 12 cases and Grade E in six cases according to American Spinal Injury Association (ASIA) classification.The operation duration,blood loss and incision length were recorded.The neurological function,lower back pain were evaluated by visual analogue score (VAS),correction of kyphosis and restoration of the fractured vertebral body height followed and documented at 3,6 and 9 months and annually after surgery.The healing of the graft was assessed using Brantigan method based on 3-dimensional computed tomography at final follow-up.Results All patients were successfully managed with this approach.The operation duration was (214.6 ± 30.5)min,and the intraoperative blood loss was (389.7 ± 57.1) ml.The length of incision was (8.5 ± 1.3) cm.All patients were followed up for (6.3 ± 0.4) years.At final follow-up,the neurological functions of all patients with incomplete neurological deficit were improved for at least one grade.The VAS of lower back pain was improved from preoperative (7.8-± 1.6) points to (2.1 ± 0.8) points at final follow-up (P ＜ 0.05).The height of the intervertebral body was restored from preoperative (29.8 ± 5.3) mm to (35.2 ± 2.4) mm at final follow-up (P ＜ 0.05).The kyphosis was corrected from preoperative (20.4 ± 11.7) ° to (11.3 ± 5.5) ° at final follow-up (P ＜ 0.05).Bone fusion was achieved in all patients,with no looseness,breakage or displacement of internal fixation at follow-up.Conclusions Anterior single segmental decompression and instrumentation through Endoring self-support retractor-assisted minimally invasive small incision approach can reduce the surgical trauma,achieve complete spinal canal decompression,adjust kyphosis,fix segment,obtain high rate of bone graft fusion and hence is a safe and effective method with minimal invasion for Denis type B thoracolumbar burst fractures.

The high incidence of coronavirus disease 2019 (COVID-19) and high mortality of critical patients have posed a great challenge to global public health resources. Currently there are no specific antiviral drugs and vaccines available for COVID-19, which has drawn the attention to the usefulness of convalescent plasma (CP) again, so the application of CP in the adult patients with COVID-19 is reviewed. The main contents include the possible mechanism of CP, the evidence of CP in the treatment of COVID-19 patients, the safety of clinical application of CP and the main factors affecting the clinical effect of CP, which may provide some basis for clinicians to choose CP for the treatment of adult patients with COVID-19.

Objective:To study the clinical features and drug resistance profile of neonatal sepsis caused by different species of Klebsiella.Methods:From January 2009 to December 2018, cryopreserved Klebsiella strains from blood culture of neonatal sepsis cases in NICU of our hospital were reactivated. Molecular identification and antimicrobial susceptibility tests were performed. Clinical features, laboratory tests, drug resistance profile and prognosis of these patients were analyzed retrospectively.Results:A total of 29 strains of Klebsiella were reactivated. Molecular identification assigned 22 cases (75.9%) into Klebsiella pneumoniae (Kpn) group and 7 cases (24.1%) into Klebsiella quasipneumoniae (Kqu) group. Gestational age and birth weight of Kpn group were higher than Kqu group [(33.1±3.2) weeks vs. (30.6±0.9) weeks, (1 847±677) g vs. (1 416±121) g] ( P<0.05). Abdominal distension was more common in Kqu group than Kpn group [42.9% (3/7) vs. 4.5% (1/22), P<0.05]. No significant differences existed in the laboratory tests including white blood cell count, platelet count, hypersensitive C-reactive protein and procalcitonin between the two groups ( P>0.05). Kpn was 100.0% sensitive to Cefazolin-Tazobactam and Amikacinto and less sensitive to Imipenem and Cefperazone-Sulbactam, Meropenem and Ertapenem. Kqu was generally more sensitive than Kpn and the sensitivity of Kqu to Imipenem was 100.0%. No significant differences existed of the prognosis between the two groups ( P>0.05). Conclusions:Kpn is the main pathogen of neonatal Klebsiella sepsis. Kqu sepsis is more common in neonates with smaller gestational age and lower birth weight. Abdominal distention is common presenting symptom in Kpn sepsis and sensitive antibiotics should be used early.
