Objective To evaluated the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of thoracic tuberculosis.Methods The study was retrospective,from September 2009 to September 2012,38 patients who underwent EBUS-TBNA were finally diagnosed of thoracic tuberculosis,with enlarged hilar or mediastinal Iymph nodes on chest enhanced computed tomography(≥ 1.0 cm).Patients in whom EBUS TBNA was nondiagnostic subsequently underwent surgical biopsy.All the patients had a minimum of 6 months clinical and radiologic follow-up.Results EBUS-TBNA was performed on a total of 88 lymph node stations in 38 patients.Of the enlarged lymph nodes,60(68.18％) were located in the mediastinal region and the remaining 28 (31.82 ％) around the hilum or interlobar area.Of the 38 patients,EBUS-TBNA achieved definitive diagnosis in 34 patients(89.47％).EBUS was well tolerated by all of the patients with no complications.Conclusion EBUS-TBNA is a safe procedure with a high yield for the diagnoses of thoracic tuberculosis.

Objective To understand the characteristics of molecular epidemiology of enterovirus 71(EV71) in children with hand, foot and mouth disease (HFMD) in Shanghai area during the first half year of 2009. Methods Seventy-three throat swabs and 38 stool samples were collected from 95 hospitalized children with clinical diagnosis of HFMD in Children's Hospital of Fudan University during April to May 2009. TaqMan real-time reverse transcription-polymerase chain reaction (RT-PCR) and nest RT-PCR were used to detect EV71 VP1, followed by gene sequencing analysis. Results Six of the 73 throat swabs were EV71 positive with the detection rate of 8.2%. In the 38 stool samples, 24 were EV71 positive with the detection rate of 63.2%. Twenty-eight nested RT-PCR positive samples were sequenced and the genetic analysis showed that 27 were C4 subtype,which were absolute dominant strain and the other one was C2 subtype. The isolated strain from a fatal case was C4 subtype and there was no obvious mutation found in VP1 region. Conclusions EV71 is an important pathogen in HFMD children in Shanghai area during April to May 2009. C4 subtype strains are absolutely dominant, and accompanied by epidemic strains of subtype C2.

Objective To study the biological effects of dose radiotherapy for primary liver cancer patients with stereotactic body portion.Methods 80 patients with primary liver cancer were selected.According to a random number table method, all patients were divided into observation group and control group,40 patients in each group.All patients were treated with stereotactic body radiotherapy treatment, the observation group was treated with high dose, while the control group received low-dose.The radiotherapy effects of different doses were analyzed and compared.Results After treatment, the effective rate of the observation group was 77.5%,which of the control group was 55.0%, ,the difference between the two groups was statistically significant (x2=4.528,P=0.033).After treatment for 6 months,1 year and 2 years, the survival rates of the observation group were 77.5%,75.0%,72.5%, which were significantly higher than 55.5%,52.5%,50.0% of the control group (P<0.05).The incidence rate of adverse reactions of the observation group was 42.5%, which was significantly lower than 72.5% of the control group (x2=7.365,P=0.006).Conclusion Stereotactic body radiotherapy treatment with different therapeutic dose has different treatment efficacy, high-dose SBRT treatment has significantly higher efficacy, survival rate and lower adverse reactions, which is worthy of clinical application.

This study is to determine six chlorogenic acids (chlorogenic acid, 5-O-caffeoylquinic acid, 4-O-caffeoylquinic acid, 3,4-di-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid) by quantitative analysis of multi-components with a single marker (QAMS). Chlorogeinc acid was used as internal reference to calculate the relative correction factors (RCF) of five compounds. Then the ruggedness of relative correction factors was tested on different instruments and columns. Meanwhile, a total of 4 batches of Lonicerae Flos and 20 batches of Lonicerae Flos extract with five different processing procedures were analyzed by external standard method (ESM) and QAMS, respectively. The ruggedness of relative correction factors was good. And the analytical results calculated by ESM and QAMS showed no difference. The quantitative method established was suitable for the quality evaluation of Lonicerae Flos extract.

A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

OBJECTIVETo investigate the clinical application of the ureteral dilation catheter combined with the balloon catheter under the ureteroscope in the treatment of urethral stricture in men.

METHODSUnder the ureteroscope, 45 male patients with urethral stricture received placement of a zebra guide wire through the strictured urethra into the bladder and then a ureteral dilation catheter along the guide wire, followed by dilation of the urethra from F8 initially to F14 and F16. Again, the ureteroscope was used to determine the length of the strictured urethra, its distance to the external urethral orifice, and whether it was normally located. An F24 balloon catheter and then a metal urethral calibrator was used for the dilation of the strictured urethra. After removal of the F18-F22 urethral catheter at 8 weeks, the urinary flow rate was measured immediately and again at 3 months.

RESULTSAll the operations were successfully performed without serious complications. The maximum urinary flow rate was (13.3-29.9) ml/s (mean [17.7 ± 3.2] ml/s) at the removal of the catheter and (15.2-30.8) ml/s (mean [19.8 ± 3.9] ml/s) at 3 months after it. Smooth urination was found in all the patients during the 6-24 months follow-up.

CONCLUSIONThe application of the ureteral dilation catheter combined with, the balloon catheter under the ureteroscope is a good option for the treatment of male urethral stricture for its advantages of uncomplicatedness, safety, effectiveness, few complications, less pain, high success rate, and repeatable operation.

As a new type of carbon nanomaterials, fluorescent carbon dots (fluorescent CDs) have many advantages when compared with the traditional fluorescent probes. They are photoluminescence stable and resistance to photo bleaching. Moreover, they are excellent in biocompatibility, low-toxic and easy to modify. All these above make them a promising optical image material as a probe in optical image. This article reviews structure, the common carbon sources, the preparation methods, and the light-emitting principles of the carbon dots. We also introduce the research progress of fluorescent carbon dots in biomedicine, and the problems need to be resolved in the study of fluorescent CDs.
