Objectives To investigate the clinical characteristics and prognosis of late-onset group B streptococcal (GBS) sepsis. Methods From Jan. 2007 to Dec. 2011, iffteen neonates diagnosed with late onset GBS sepsis at discharge from NICU were retrospectively analyzed, meanwhile, thirty-four neonates diagnosed with late onset non-GBS Gram-positive bacteria sepsis at discharge were selected as controls during the same period. Results There were signiifcant differences in occurrence rates of shortness of breath, convulsion and apnea between late onset non-GBS sepsis group and late onset GBS sepsis group (P<0.05). The percentages of neonates with white blood cell count (CSF)>100×106/L, high-sensitivity C-reaction protein (hsCRP)>100 mg/L and glucose in CSF<3.11 mmol/L in late onset GBS sepsis group were higher than those in late onset non-GBS sepsis group (P<0.05). GBS was sensitive to penicillin, ampicillin, ceftriaxone, piperacillin/tazobactam, levolfoxacin and vancomycin. The rates of GBS resistance to erythromycin and gentamycin were both 87.5%. There were signiifcant differences in occurrence rates of meningitis, hydrocephalus and ependymitis between late onset GBS sepsis group and late onset non-GBS sepsis group (P<0.05), while no difference in mortality was found between two groups (P>0.05). Conclusions The late onset GBS sepsis is in-sidious, atypical, with many complications and sequelae. It is important for the suspicious neonates to use effective antibiotics as early as possible.

BACKGROUND: Human lower limb system under different motion statuses exhibits great difference in terms of kinetic characteristics and joint deformation magnitude. Total hip replacement has been shown to be the best method to solve the severe illness of hip joints today. A good understanding of the responses of human lower limb system, in particular the knee joint, following total hip replacement is significant for rehabilitation training of patients.OBJECTIVE: To analyze the effects of total hip replacement on knee joint deformation during motions by comparing the data collected from a patient who underwent total hip replacement 19 months ago and a healthy control subject under the same testing environment and method.METHODS: The patient was measured through the use of Optotrak Certus motion capture system (Northern Digital Inc.,California), and simultaneously measurements were performed in a healthy control subject presenting with similar body weight and body mass. Measurement indices included step length, step frequency, joint corner, and joint displacement curves. Speed and acceleration of each joint were calculated based on measured data.RESULTS AND CONCLUSION: Following total hip replacement, the structure of natural hip joint was destroyed. Although the gait did not change greatly, experimental data showed that knee joint deformed more greatly than normal gait, indicating the self-accommodation of human body, i.e., increasing the loading and deformation magnitude of knee joints can avoid the injuries caused by hip joint surgery.

Objective To introduce the techniques and specification of complete-block radical gastrectomy, and to compare with traditional radical gastrectomy in the operative time, surgical costs and postoperative complications. Methods Thirty gastric cancer patients meet the criteria were randomly divided into 2 groups. Group A: complete-block radical gastrectomy;group B: radical gastrectomy. Analysis and comparison were made on tumor site, time consuming of block, the proportion of gastrointestinal reconstruction, operative time, cost of block, pathological TNM stage, length of stay, postoperative complications and postoperative chemotherapy. Results Group A has longer operative time than group B (P<0.05). However, there was no significant statistical difference in the other indicators between these 2 groups. Conclusions Complete-block technology can separate cancer more completely during operation with the advantage of simplicity, low-cost, little effect on the subsequent operation. The incidence of postoperative complications and length of stay with the traditional surgery there was no significant difference.

Objective To evaluate the effectiveness of intratracheal injection of pulmonary surfactant (LISA) combined with continuous positive airway pressure (CPAP) on the treatment of neonatal respiratory distress syndrome (RDS). Methods The databases of PubMed, EMBASE, Cochrane, China National Knowledge Infrastructure (CNKI), Wanfang Database, Weipu Database and China Biology Medicine disc (CBM) were searched, and all of the randomized controlled trial of LISA combined with CPAP for treatment of RDS were included. RevMan 5.2 was used to perform meta-analysis. The differences of mortality, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), and other complications between LISA group and control group were compared in <34 weeks gestational age preterm infants with RDS. Results Five randomized controlled trials were included with 759 infants in total. Compared with control group, the rate of mechanical ventilation (RR: 0.32,95% CI: 0.13-0.82) and the incidence of BPD (RR: 0.61,95%CI: 0.42-0.88) were significantly decreased in LISA group. There were no differences in mortality and the incidences of ROP, IVH, and PVL between two groups (P>0.05). Conclusion The mechanical ventilation and the incidence of BPD is significantly reduced in the treatment of neonatal respiratory distress syndrome by LISA, but it has no effect on the incidences of other complications and mortality.
