Objective To analyze and evaluate neoadjuvant chemotherapy's value and significance in combining with surgical treatment for limited small cell lung cancer(LD-SCLC).Methods A total of 94 LD-SCLC patients underwent complete resections combined with chemotherapy between January 2000 and January 2011 in Shanghai Pulmonary Hospital.Among these cases,initial two cycles of neoadjuvant chemotherapies were performed for all pathologically confirmed patients (Group A),and initial operations followed by adjuvant chemotherapy were administered to patients without pathology (Group B).The survival rate was analyzed by log-rank test and Kaplan-Meier method.Multivariate analysis of the prognostic factors was performed using Cox's regression model.Results Group A included 43 cases and Group B included 51 cases.The mean age was (56.37 ± 10.18) years.According to the 6th edition of Tumor,Node,Metastasis(TNM) classification of lung cancer,54 cases were at stage Ⅰ or Ⅱ,40 cases were at stage Ⅲ.Overall 5-year survival(5-YS) was 27%.The 5-YS for patients with stage Ⅰ-Ⅱ was notably better than that of stage Ⅲ (34% vs 20%,P =0.033).For patients with stage Ⅲ,the 5-YS of Group A was significantly better than that of Group B(34% vs 12%,P =0.020),besides median overall survival for Group A and Group B were 46 and 15 months(P =0.009).Furthermore,the results of multivariate analysis showed that neoadjuvant chemotherapy,surgery and histopathology of SCLC were independent factors that strongly affected survival and prognosis.Conclusion In combined surgical treatment for LD-SCLC,neoadjuvant chemotherapy obviously improved the prognosis of patients with stage Ⅲ.Therefore,it was very important and necessary that pre-surgical neoadjuvant chemotherapy was administered to resectable stage Ⅲ LD-SCLC patients.

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.

OBJECTIVETo explore the clinical application of mandibular-driven simultaneous maxillo-mandihular distraction to correct hemifacial microsomia with rapid prototyping technology.
METHODSThe patient' s skull resin model was manufactured with rapid prototyping technology. The osteotomy was designed on skull resin model. According to the preoperative design, the patients underwent Le Fort I osteotomy and mandibular ramus osteotomy. The internal mandible distractor was embedded onto the osteotomy position. The occlusal titanium pin was implanted. Distraction were carried out by mandibular-driven simultaneous maxillo-mandihular distraction 5 days after operation.
RESULTSThe distraction in five patients was complete as designed. No infection and dysosteogenesis happened. The longest distance of distraction was 28 mm, and the shortest distance was 16 mm. The facial asymmetry deformity was significantly improved at the end of distraction. The ocelusal plane of patients obviously improved.
CONCLUSIONSRapid prototyping technology is helpful to design precisely osteotomy before operation. Mandibular-driven simultaneous maxillo-mandibular distraction can correct hemifacial microsomia. It is worth to clinical application.

To discover novel fluoroquinolone lead compounds as possible anti-infective or/and antitumor chemotherapies, combination principle of pharmacophore-based drug design, a series of novel tricyclic fluoroquinolone title compounds, [1,2,4]triazino[3,4-h][1,8]naphthyridine-8-one-7-carboxylic acid derivatives ( 5a-5p), were designed and synthesized with a fused [1,2,4]-triazine ring unit. Their structures were characterized by spectral data and elemental analysis and the in vitro antibacterial and anti-cell proliferation activities were also evaluated. The results showed that the titled compounds exhibited more significant inhibitory activities against drug-resistant bacteria (Methicillin-resistant Staphylococcus aureus and multi drug-resistant Escherichia coli strains) and three tested cancer cell lines (human hepatoma SMMC-7721, murine leukemia L1210 and human murine leukemia HL60 cells). Interestingly, SAR showed that compounds with electron-donating groups attached to benzene ring had stronger antibacterial activity than antitumor activity, but electron-withdrawing compounds displayed more potential antitumor activity than antibacterial activity, especially antitumor activity of nitro compounds was comparable to comparison doxorubicin. Thus, novel triazine-fused tricyclic fluoroquinolones as potent anti-infective or/and antitumor lead compounds are valuable to pay attention and for further development.

Objective To investigate the value of contrast enhanced ultrasonography (CEUS) in the treatment of small hepatic malignancies with radiofrequency ablation(RFA). Methods Seventy patients with 104 pathologically proved malignant liver lesions treated by RFA (size 0.7 -2.7 cm) were divided into 2 groups including CEUS group and control group. In CEUS group,39 patients(54 lesions) were treated with RFA guided by CEUS, while in control group 31 patients (50 lesions) were guided by conventional ultrasonography. There was no significant difference between clinical data of the two groups. Results Seventeen tumors(among them,12 lesions were less than 1.5 cm in diameter) in 13 patients showed more clearly on CEUS image than on conventional ultrasonography image (31.5% ) in CEUS group. The tumor necrosis rate at one month after RFA was 100% in CEUS group,and 92% in control group ( P = 0. 034).The number of RFA sessions per tumor was 1.00± 0.00 in CEUS group,and 1.08 ± 0.27 in control group (P = 0.000). Local tumor progression rate was 0 in CEUS group and 4% in control group ( P = 0. 138)during the period of 8 - 52 months follow-up (average 21 months). Conclusions CEUS can not only improve the display of small hepatic malignancies but also provide precise guidance in contrast with conventional ultrasonography. Compared with control group, RFA of small hepatic malignancies guided by CEUS lower the number of RFA sessions, enhance the tumor necrosis rate, decrease post-RFA local progression and therefore it has extensive clinical value.
