Objective To investigate the impact of surgical resection on patients with Ⅱ-Ⅲ A stage small cell lung carcinoma (SCLC). Method Data of 61 in-patients who diagnosed as Ⅱ-ⅢA stage SCLC from Jan 1st 2009 to Feb 1st 2014 were analyzed. 23 patients underwent surgical resections were enrolled as the treatment group, while 38 patients without surgical resection were enrolled as the control group. Disease progression was confirmed by monthly examination. The grouping is balanced by propensity score match. The progression-free survival (PFS) time and overall survival(OS) were analyzed with Kaplan-Meier survival method and Cox regression is applied to analyze the covariates. Fisher's exact test was applied to compare one-year survival rate and two-year survival rate. Results The PFS and OS of the treatment group is longer than that of the control group (P < 0.05). Both one-year and two-year survival rates of the treatment group outnumber those of the control group (P < 0.05). Cox regression indicates that surgical resection is an independent prognostic factor (P < 0.05). Conclusion Surgical resection on tolerable patients with stage Ⅱ-Ⅲ A small-cell lung carcinoma is effective on improving the progression-free survival time,one-year and two-year survival rates,and also shows a propensity of a higher overall survival time.

Objective To investigate the consistency in 18F-deoxyglucose positron emission tomography (18F-FDG PET-CT) examination and histopathological analyses in the diagnoses of resectable lung tumors. Methods Retrospective reviews over the clinical data of lung tumor patients by preoperative PET-CT diagnosis and postoperative histopathological diagnosis were conducted to investigate the effects of the two diagnostic methods in terms of lung tumor properties , mediastinal lymph node metastasis , and pulmonary hilar lymph node metastasis. Results The diagnoses by preoperative PET-CT was consistent in differentiation of non-malignancy and malignancy of pathologic lung tumors by 87.3%, at a medium level (κ = 0.401, P < 0.001). McNemar test showed P = 0.508, indicating the two diagnostic methods were insignificantly different in the diagnosis of pulmonary tumors. The preoperative PET-CT was consistent in the diagnosis of the metastasis of pathologic mediastinal lymph node by 85.9%, at a medium level (κ = 0.697, P < 0.001). McNemar test showed P =0.754, indicating no significant difference between the diagnostic methods. The preoperative PET-CT was consistent with postoperative pathological examinations in the differentiations of the metastasis of pulmonary and hilar lymph node by 77.4%, at a medium level (κ=0.523, P < 0.001). McNemar test showed P = 0.454, indicating the two diagnostic methods were no significantly different. Conclusion Preoperative PET-CT and histopathologic examinations may be consistent in lung tumor diagnosis , which provides a basis for a certain significance in the surgical options.

Objective To explore the effect and mechanism of L-arginine on fetal growth restriction by observing the expression of Bcl-2 and Bax in placenta.Methods Sixty patients with FGR were chosen,among which 30 cases who were treated with conventional ways were as convention group,and the other 30 cases who were treated with L-arginine were as L-arginine group.The birth weight and perinatal fetus outcome were detected.The central tissue of placenta got within 10 min after delivery were fixed by 100 g/L formaldehyde and embed by pa-raffin wax to observe the expression of Bcl-2 and Bax using immunohistochemistry.SPSS 11.5 software was used to analyze the data.Results Compared with convention group,the birth weight of L-arginine group was higher(P

The vip3A gene of Bt9816C was cloned and the sequencing result was submitted to GenBank (accession no.AY945939). The gene was identified as a novel vip3Aa gene, which was assigned name vip3Aa18 by the Bacillus thuringiensis delta-endotoxin nomenclature committee. Subsequently, vip3Aa18 was expressed in Escherichia coli BL21 and bioassay demonstrated that the purified recombinant Vip3Aa18 had high toxicity against Helicoverpa armigera and Spodoptera exigua. The results of sequence analysis revealed that a carbohydrate binding domain exists on the C-termini 536 to 667 residues of Vip3Aa18,which maybe participate in binding to midgut receptors in susceptible insects. Moreover, a transmembrane helices located on N-termini 272 to 292 residues was proposed responding for pore formation. Furthermore, a putative disulfide bond was found in the Vip3Aa18 sequence. The specific structures and sites of Vip3Aa18 sequence imply potential function.

OBJECTIVETo study the effects of valproate sodium (VPA) on the level and axle of pituitary gonadotropin in adolescent girls with epilepsy.

METHODSTwenty-three adolescent girls with epilepsy aged from 8 to 14 years were treated with VPA for 1 year. The levels of serum pituitary gonadotropin including estradiol, follicle-stimulating hormone, luteinizing hormone, prolactin and testosterone were measured before treatment and 3 months, 6 months and 1 year after treatment.

RESULTSThe serum levels of estradiol, follicle-stimulating hormone, luteinizing hormone and prolactin in the children with epilepsy were not significantly different during the 1 year VPA treatment compared with pretreatment. However, the serum level of testosterone was reduced 1 year after treatment (0.4±0.3 ng/mL) compared with pretreatment (0.7±0.4 ng/mL) and 3 months after treatment (0.7±0.4 ng/mL) (P<0.05).

CONCLUSIONSVPA treatment for 1 year does not increase serum levels of androgen in adolescent girls with epilepsy, suggesting that VPA is an ideal choice of treatment for the girls.

OBJECTIVETo compare the clinical effects between hip anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery and posterior K-L approach combined with quadratus femoris bone flap transplantation for the treatment of femoral neck fracture of Garden III-IV in young and middle-aged patients.

METHODSFrom January 2004 to January 2011,46 patients with femoral neck fractures were treated by two kinds of operation. Among them, 20 cases were treated with anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery, included 12 males and 8 females with an average age of (32.1 ± 7.3) years old, involved 12 cases of Garden III and 8 cases of Garden IV. The other 26 cases were treated with posterior K-L approach combined with quadratus femoris bone flap transplantation, included 20 males and 6 females with an average age of (37.8 ± 6.9) years old, involved 16 cases of Garden III and 10 cases of Garden IV. The index of hospitalization (hospitalization time, total cost, operative time, intraoperative blood loss, postoperative complications), the quality index of operation (fracture reduction, position of internal fixation, fracture healing time, nonunion and femoral head necrosis) of two groups were observed and compared. Hip joint function were evaluated by Harris score.

RESULTSAll patients were followed up from 28 to 41 months with an average of 36 months. The intraoperative blood loss of group S-P (92.3 ± 10.4) ml was less than that of group K-L (132.4 ± 11.2) ml, there was significant difference between two groups (P < 0.05). The operation time of group S-P (81.4 ± 9.2) min was more than that of group K-L (67.1 ± 4.5) min, the difference was statistically significant (P < 0.05). One case in group S-P and 9 cases in group K-L appeared postoperative complications, there was significant difference between two groups (P < 0.05). The fracture healing time of S-P group (83.5 ± 7.3) d was shorter than that of group K-L (103.2 ± 12.6) d, there was significant difference between two groups (P < 0.05). At 30 months after operation, there were significant difference in Harris scoring between two groups (P < 0.05).

CONCLUSIONAnterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery for treatment of femoral neck fracture of Garden III-IV of young and middle-aged patients, it has characteristics in clear anatomic and easy to operate. As compared with K-L approach, S-P approach can better reserve residual blood supply of femoral neck. While combining with the iliac bone flap transplantation with deep circumflex iliac artery, it could better reconstruct the blood supply of femoral neck to promote fracture healing.
