Objective To explore preliminary clinical results of a new anatomical shape allogeneic bone posterior lumbar fusion cage. Methods Follow-up patients used the allogeneic bone posterior lumbar fusion cage and use imaging methods and clinical score (VAS, ODI) to evaluate the patients′ clinical efficacy. Results 14 patients were followed up for 6 months or more , with an average follow-up time of 9.7 months , mean preoperative VAS 6.8 ± 1.1, ODI 32.7 ± 4.5. The mean preoperative disc height was (9.7 ± 2.0) mm and the average intervertebral height of 3 days post operation was (13.2 ± 1.7) mm. All patients got bony fusion in 6 months post operation, pain and function scores improved significantly compared with the pre-operation: VAS 2.4 ± 0.8 (P =0.000), ODI 9.8 ± 2.5 (P = 0.000), the average intervertebral height was (13.1 ± 1.7) mm (P = 0.000). The average was VAS 2.1 ± 0.1 (P = 0.000), average ODI was 8.9 ± 0.9 (P = 0.000) at last follow up. Average of intervertebral height was (13.0 ± 1.8) mm, no significant difference compared to three days after surgery (P=0.831). No serious complications and deep surgical site infection was observed. All implants were found no fragmentation, shift, cutting boards, and obviously sinking. Conclusion The anatomical shape allogeneic bone posterior lumbar fusion device is suitable for posterior lumbar interbody fusion , advantages of high fusion rate , satisfactory clinical results in the initial clinical trials , but its long-term efficacy requires further observation.

Objective To explore the clinical characteristics and prognostic factors of breast carcinosarcoma.Methods Clinical data of 37 breast carcinosarcoma patients treated at Tianjin Cancer Hospital from 1974 to 2014 was analyzed retrospectively.Kaplan-Meier unvariate analysis was used to calculate the survival rate and compare the survival rates.Multivariate factors for survival were analyzed by COX proportional hazards regression model.Results 37 cases of breast carcinosarcoma were all female.The median age was 55 years.Among them 31 cases complained for painless mass,six cases had breast mass with skin ulceration.21 cases were three-negative breast cancer.Ten cases had axillary lymph node metastasis,ten cases had distant metastasis.The 5-year survival rate was 62.3％.Unvariate analysis showed that axillary lymphnodes metastasis (P =0.045) and therapeutic schedule (P =0.016) significantly influenced the oulcome of the patients.COX multivariate analysis validated that the therapy modality was an independent prognostic factor for breast carcinosarcoma(P =0.041).Conclusions Breast carcinosarcoma is rare and has a poor prognosis.ER,PR and HER-2 expressions in most cases are negative.If there is axillary lymph node metastasis,the prognosis is poor.A reasonable and comprehensive treatment can improve the prognosis.

Objective To explore clinical features and antimicrobial resistance of Klebsiella pneumoniae (K.pneumoniae) lower respiratory tract infection(LRTI) in children.Methods Clinical data of 107 children with K.pneumoniae LRTI confirmed by sputum culture from January to December 2015 were analyzed retrospectively.Results 62.62% of children with LRTI were aged less than 6 months and 64.49% episodes occurred in autumn and winter.All cases had cough and 39 had fever, the main complications were type I respiratory failure, type Ⅱ respiratory failure, cardiac insufficiency, and electrolyte disturbance, 39 cases(36.45%) had complications involving two systems, 5 cases(4.67%)had complications involving three systems,47 cases (43.93%) met the diagnostic criteria of severe pneumonia.43 cases (40.19%) had primary underlying diseases, the major were congenital heart disease, preterm and low birth weight, and malnutrition.Children with imipenem-resistant bacteria infection were more prone to develop extrapulmonary complications than those with non-resistant pathogenic infection.The resistance rate of K.pneumoniae to amikacin was the lowest(9.35%).90 cases were recovered and markedly effective, 11 cases were effective, 4 cases were not healed and voluntarily discharged from hospital, and 2 cases died.Conclusion Children aged less than 6 months and with underlying diseases are prone to develop LRTI, and complications are more.

Objective To evaluate the association between bradycardia and neurological sequel in patients with restoration of spontaneous circulation (ROSC) after cardiopulmonary resuscitation (CPR) during targeted body temperature management (TTM).Methods Forty-three unconscious patients with ROSC after CPR were treated with TTP.The patients were cooled with therapeutic hypothermia to body temperature target range (32-34°C) after cardiac arrest and divided into bradycardia and control groups depending on the lowest heart rate less than 50 beats/min and more than or equal to 50 beats/min respcetively at that time.The bispectral index (BIS) and the neuron-specific enolase (NSE) values were respectively recorded at the following intervals,0h (h0)、24h (h24)、48h (h48)、72h (h72) after ICU admission.Neurological outcome was defined according to the Pittsburgh cerebral performance category (CPC) at 3 months after ICU discharge.Results Compared with the control group,during TTM the bispectral index levels were significantly higher in the bradycardia group at h0,h48,h72 after admission,(h0 bradycardia group 73.0 ± 12.3;control group 58.0 ± 18.6,P ＜0.01)、(h48 bradycardia group 71.4 ± 21.2;control group 46.3 ± 18.9,P ＜ 0.01)、(h72 bradycardia group 78.6 ± 24.6;control group 51.8 ± 24.1,P =0.01).The neuron-specific enolase level in bradycardia group was significantly lower than that in control group on day3 (118.8 ± 118.8 ng/mL vs.248.3 ± 191.9 ng/mL,P =0.02).The level of CPC in the bradycardia group was significantly higher than that in the control group (P =0.046).Conclusions Patients with bradycardia during TTM had favorable neurological outcome,which could provide evidence for clinical treatment and prognostic evaluation of the patients.

Objective To evaluate the prognostic value of the neuron-specific enolase ( NSE ) and bispectral index ( BIS) in patient with mild therapeutic hypothermia ( MTH) after cardiopulmonary resuscitation ( CPR ) .Methods Forty-six patients with restoration of spontaneous circulation ( ROSC ) after CPR were treated with MTH.The BIS values were recorded and the serum NSE was measured at the following times:24 h, 48 h, and 72 hours after ICU admission.Neurological outcome was classified according to the Pittsburgh cerebral performance category ( CPC 1 to 5) at 3 months after ICU discharge.Results Fourteen patients had a good neurological outcome with CPC score 1-3, and thirty-two patients had a poor neurological outcome with CPC 4-5 at 3 month.Compared with good outcome group, the NSE values were significantly higher in the poor outcome group on day 2 and day 3 after admission [48 h: (90.1 ±42.7) ng/mL vs.(33.2 ±17.5) ng/mL;72 h: (95.4 ±37.0) ng/mL vs. (29.2 ±17.0) ng/mL, P<0.05].NSE increased markedly in the poor neurological outcome group at 48h and 72h, and decreased significantly in the good group at the same time [△NSE 24 h-48 h: (37.3 ±28.7) ng/mL vs.(-10.7 ±12.1) ng/mL; △NSE 48 h-72h: (5.3 ±13.2) ng/mL vs.(-4.0 ±4.5 ng/mL), P<0.05].Over the 72 h of monitoring, the mean BIS values were lower in the poor outcome group compared to the good outcome group at 48 h [ (39.2 ±24.1) vs.(78.0 ±12.4); 72 h: (45.7 ±26.4) vs.(89.0 ±7.3), P<0.05].Conclusions The values of NSE and BIS were effective prognostic indicators for the neurological outcome of patients with MTH after CPR.

OBJECTIVETo evaluate the application of shear wave elastography (SWE) combined with transition zone biopsy in the detection of prostate cancer (PCa).

METHODSA total of 489 patients with suspected PCa underwent transrectal ultrasonography (TRUS) and SWE-guided prostatic biopsy. We evaluated the role of SWE combined with transition zone biopsy in promoting the detection rate in comparison with the results of biopsy pathology.

RESULTSThe pathological results confirmed 221 malignant and 268 benign cases. Based on systematic biopsy, SWE combined with transition zone biopsy achieved a detection rate of 45. 19% , significantly higher than that of systematic biopsy alone (33.13%) (P < 0.05). The diagnostic sensitivity, specificity, and accuracy of SWE were significantly better than those of TRUS (P < 0.05). The mean elasticity (Emean) of SWE was remarkably higher for malignant than for benign lesions ([40.1 ± 9.5] vs [21.6 ± 8.3] kPa, P < 0.05). With 28.5 kPa as the threshold of the Emean value, the area under the ROC curve was 0. 899, and the diagnostic sensitivity and specificity were 88.71% and 86.23%, respectively.

CONCLUSIONSWE combined with transition zone biopsy could significantly improve the detection rate of prostate cancer.
