Objective To compare the therapeutic effects of 1470nm diode laser vaporization prostatectomy and bipolar transurethral plasmakinetic prostatectomy (TUPKP) for treatment of benign prostatic hyperplasia (BPH).Methods From June 2015-February 2016 a total of 95 patients diagnosed with BPH were randomly divided into 2 group:52 patients were treated with TUPKP while 43 patients with 1470 diode laser.All patients were followed up with mean operative time,intra-operative blood loss,postoperative hospital stay,postoperative catheterization time,postoperative complications,international prostate symptom score (IPSS),score of life quality (QoL),maximum flow rate (Qmax),post-void residual (PVR) before and after surgery.Results Compared with data of preoperation,postoperative IPSS,QoL,Qmax,PVR in 6 months revealed significant improvement in both of two groups.IPSS of TUPKP group and 1470 group respectively dropped to 6.3 ± 2.6 and 6.7 ± 2.4.In TUPKP group,PVR reduced to 23.1 ± 20.9ml and in 1470 group decreased to 24.3 ± 19.9ml.While Qmax increased to 18.5 ± 3.1 ml/s and 18.7 ± 2.8ml/s respectively in TUPKP and 1470 group.In TUPKP group,operation time were 60.1 ± 14.9min,significantly less than that in 1470 group of 69.3 ± 12.9min (P ＜ 0.05).Compared with catheterization time in 1470 group of 33.9 ± 9.4h,the time in TUPKP group of 73.9 ± 37.6h was shorter with significant difference (P ＜ 0.05).While Curative effect of two groups of showed no significant difference (P ＞ 0.05).Conclusion The clinical curative effect of two operation methods for patients with BPH showed no significant difference.1470 group had longer operation time,while TUPKP group had less intraoperative bleeding and postoperative recovery.

Recently,the incidence rate of small cell lung cancer in elderly patients has been increasing . The mainly therapeutic approach of small cell lung cancer consists of radiotherapy ,chemotherapy and surgery ,with the treatment purpose of prolonging survival time and improving life quality .As the huge development of accurate radiotherapy technology occurred in the past a few years ,radiotherapy could play more and more important roles in the treatment with elderly patients .Yet,there is no unified standards of treatment for small cell lung cancer in eld-erly patients.Therefore,we give a review on the latest processes and research on the treatment of small cells lung cancer in elderly patients .

Objective:To study the effect and underlying mechanism of rosmarinic acid in the apoptosis of HepG2 cells. Meth-ods:An MTT method was used to determine the inhibitory effect on the growth of HepG2 cells treated with rosmarinic acid for 48 hours. Flow cytometry was used to detect the cell apoptosis after treated with rosmarinic acid at different concentrations for 24 h and 48 h. Western Blotting was used to detect the expression of P53 and c-Myc protein after treated with rosmarinic acid for 48 h. Results:When HepG2 cells were treated with rosmarinic acid at the concentrations of 12. 50, 25. 00, 50. 00 and 100. 00 μg·ml-1 for 48 h, the cell growth was inhibited and the half-inhibitory concentration (IC50) was 43. 48μg·ml-1. By comparing HepG2 cells treated with rosma-rinic acid at different concentrations for 24 h and 48 h, rosmarinic acid had the effect on the early apoptosis of HepG2 cells after the 48-hour treatment. When treated with rosmarinic acid at the different concentrations for 48 h, the expression of c-Myc decreased with the concentration increase of rosmarinic acid, and the expression of P53 increased with the concentration increase of rosmarinic acid. Con-clusion:The inhibitory effect of rosmarinic acid on the proliferation of HepG2 cells is in a dose-dependent manner, and it can promote the apoptosis of HepG2 cells through the activation of P53 and the cleavage of proto-oncogene c-Myc protein.

Objective To investigate the correlation between red cell distribution width RDW) and prognosis in patients with severe traumatic brain injury.Methods A total of 264 consecutive patients with severe traumatic brain injury admitted from May 2012 to November 2014 were enrolled.The patients were divided into low-RDW group (RDW ＜ 15％,n =198) and high-RDW group (RDW ≥ 15％,n =66) based on their RDW levels.Between-group differences were evaluated on general conditions,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ),inflammatory markers [high sensitivity C-reactive proteins(hs-CRP) and arterial lactate],liver/renal dysfunction,and 28-day mortality.Spearman correlation analysis of RDW with mortality was conducted.Independent factors of 28-day mortality were identified using multivariate Logistic regression.Kaplan-Meier 28-day survival curve was analyzed and survival probability of the two groups was compared using Log-Rank test.Results The 28-day mortality was significantly enhanced in high-RDW group compared to that in lowRDW group (43.9％ vs 26.8％,P ＜ 0.01).RDW ≥ 15％ related positively to APACHE Ⅱ and mortality(r =0.172 and 0.253 respectively,P ＜ 0.01),but negatively to Glagow coma score (GCS) (r =-0.169,P ＜0.01).RDW≥ 15％ was the independent risk factor for predicting the 28-day mortality (OR =2.144,95％ CI 1.202-3.826,P ＜0.01).After adjusted gender,age,and other relative factors,RDW≥15％ was still strongly correlated with the 28-day mortality(OR =2.244,95％ CI 1.076-4.678,P ＜ 0.05).Significantly lower 28-day survival rate was found in high-RDW group than in low-RDW group (P ＜ 0.01).Conclusions RDW level rises beyond the normal range on admission in patients with severe traumatic brain injury,which is closely correlated with the 28-day poor outcome.RDW≥ 15％ has significant predictive value in the prognosis.

Purpose To explore the clinicopathologic characteristics, pathologic diagnosis and differential diagnosis of extraskeletal myxiod chondrosarcoma. Methods The clinical and pathological features were studied with HE and immunohistochemical staining in 5 cases of extraskeletal myxoid chondrosarcoma, and the related literatures were also reviewed. Results Extraskeletal myxoid chondro-sarcoma was male predominance (4 males: 1 female), and the age ranged from 32 to 62 years with an average of 52 years. Four tumors occurred in thigh and another in chest. Histologically, the neophlasm were composed of round and oval cells. Immunohisto-chemically, the tumor cells were positive for vimentin in five cases, synaptophysin expressed in one case, S-100 showed focal positivity in two cases, but negative for CK, p63, EMA, CD34, SMA in all cases. Molecular genetics detection shows chromosome exchange be-tween number 9 and 22. Conclusion Extraskeletal myxoid chondrosarcoma is a rare tumor which has no special characteristics in clinical and iconography, and its diagnosis mainly depends on the histopathologic features, immunohistochemistry and molecular genet-ics. Extraskeletal myxoid chondrosarcoma grows slowly, but have a high tendency for local recurrence and metastases.

The etiological agent of severe acute respiratory syndrome (SARS) was identified as a new coronavirus, termed SARS-CoV. Establishment of an efficient and sensitive diagnostic system of SARS-CoV genetic materials is crucial for SARS control. In this study, we quantified SARS-CoV mRNAs in both infected cell culture lysate and in supernatant by using Real-time quantitative revere transcription-PCR based on EvaGreen鈩?dye and Taqman-MGB probes. For extensive evaluation of sensitivities and specificities, 13 pairs of primers and 4 probes were designed based on different genes of SARS-CoV. Glyceraldehydes-3-phosphate dehydrogenase (GAPDH) was selected as the internal control gene. Results showed that S-gene-specific PCR was the most sensitive for detection, but because of its sequence variability in the different viral strains, primers and a probe based on the N gene were suitable substitutions. Meanwhile, we found the mRNA concentrations in cell culture lysates were much higher than in cell supernatant and facilited more sensitive detection of the SARS-CoV.
