Objective To observe the clinical efficacy and safety of etoposide capsule (VP16) in the treatment of recurrent small cell lung cancer. Methods Retrospective analysis 39 patients,aged≥65, with relapsed small cell lung cancer, who were at least three months after the end of the first-line treatment since January 2012 to January 2014 in Tianjin fifth central hospital.Etoposide was administered by daily oral at 100 mg/day for seven consecutive days and withdraw for 14 days,21 days as a therapeutic cycle,repeat treatment until disease progression or intolerable side effects occur, analyze the progression-free survival and overall survival.Observe the clinical benefit rate,the overall response rate and safety.Results The clinical benefit rate (DCR) and overall response rate (ORR) after the treatment were 61.5% and 30.77%.The progression-free survival (PFS) was 2.8 months, and the overall survival (OS) was 7.3 months.Neutropenia is the most common toxicities, and grade Ⅲ or Ⅳ occurred in 7.7% of the patients.No grade Ⅲ or Ⅳ thrombocytopenia, or grade Ⅲ or Ⅳ non-hematologic toxicity was occured.Conclusion Etoposide oral capsules monotherapy may be considered as one of the safe and effective choice of the second-line treatment of elderly patients with relapsed small cell lung cancer.

Objective To determine the clinical characteristics of post ictal headache (PIH) and clinical risk factors associated with the occurrence of PIH in patients with localization related epilepsy.Methods The subjects were 47 patients with temporal lobe epilepsy (TLE),21 patients with occipital lobe epilepsy (OLE),and 29 patients with frontal lobe epilepsy (FLE).The subjects were directly asked whether headaches occurred just after seizures and its characteristics.Results The characteristics of PIH were:throbbing quality,which was exacerbated by coughing,vomiting,bending,and sudden head movement,accompanied by photophobia,phonophobia,and relieved by sleep.The incidence of PIH was 21 3% for TLE,61 9% for OLE,and 41 4% for FLE.The risk of PIH was significantly higher for OLE than for TLE or FLE,and for patients with generalized tonic clonic seizures.Younger onset age of epilepsy was also a risk factor for PIH.Conclusions PIH possess some characteristics similar to migraine.The occurrence of PIH may be related to the region of epileptic focus and the region of the spread of epileptic discharges.

Objective To detect serum Vaspin level in subjects with normal glucose regulation(NGR)and newly-diagnosed type 2 diabetes mellitus (T2DM) ,and to investigate the association between serum Vaspin and body mass index (BMI), age, gender, glycometabolism and lipemetabolism and insulin sensitivity index. Methods The fasting serum levels of Vaspin were measured in 48 normal controls and 66 T2DM patients using enzyme linked immunosorbent assay ( ELISA ). BMI, waist-hip ratio (WHR) and % body fat were measured,as well as fasting blood glucose (FBG), HBA1C, lipids and insulin levels. Results The fast serum Vaspin concentrations in the obese T2DM patients was ( 1.13 ±0. 25 ) μg/L,which were significantly higher than that in the non-obese T2DM patients (0. 65 ± 0. 13 ) μg/L (P ＜ 0. 01 ). In the NGR group, the fast serum Vaspin concentrations in the obese was (0. 95 ± 0. 11 ) μg/L, which were significantly higher than that in the non-obese (0. 38 ± 0. 18) μg/L( P ＜ 0. 01 ). In the T2DM group, serum Vaspin concentration in females ( [0. 92 ± 0. 35]μg/L) was higher than in males ([0.76 ± 0. 22] μg/L) (P ＜ 0.01 ). In the NGR group, serum Vaspin concentration in females was also higher than that in males ( [1.05 ± 0. 21] μg/L vs [0. 48 ± 0. 14] μg/L) )(P＜0. 01 ). Serum Vaspin level was positively correlated with BMI,WHR,% Body Fat,fasting insulin(FINS)and insulin sensitivity index (ISI) (r = 0. 365,0. 214,0. 238,0. 183 and 0. 147, respectively, Ps ＜ 0. 05 ). The multiple stepwise regression analysis showed that gender( R2 = 0. 161, P ＜ 0. 01 ), ISI ( R2 = 0. 183, P ＜ 0. 01 )and WHR( R2 = 0. 216, P ＜ 0. 01 ) were independent variables associated with Vaspin. Conclusion Serum vaspin level significantly increases in subjects with obesity, and independently associated with gender, ISI,WHR. These findings suggest that serum Vaspin may be involved in the pathophysiology of insulin resistance syndrome.

The 1-year, 3-year and 5-year FACT-G score in control group were higher than that in control group ( < 0.05). Conclusion Laparoscopic surgery for cervical cancer patients can reduce bleeding, shorten exhaust time and hospitalization time, improve postoperative FACT-G score and postoperative quality of life of cervical cancer pa-tients.

Objective To evaluate the hinged external flxator in combination with internal fixation for treatment of old type B fractures of the distal humerus.Methods Eleven cases of old type B fractures of distal humerus treated in our department were studied retrospectively.They were treated with hinged external fixators in combination with internal fixation and evaluated according to Mayo elbow performance scores.Results All the patients were followed up for 10 to 18(mean, 12.5)months.The mean union time was 4.6(range, 3.5 to 6.0)months.The final range of flexion to extension of the elbow was 19.4°±6.5° to 124.2°±11.3°.The final ranges of pronation and supination were 72.8°±5.4° and 67.6°± 7.3°.By Mayo elbow performance scores, the post-operative functional outcome of the elbow was excellent in 5 patients, good in 4, and fair in 2.Conclusion The old type B fractures of distal humerus can be effectively treated with hinged external fixators in combination with internal fixation, for early rehabilitation and restoration of the elbow function can be facilitated.

Objective To obtain the specific human scFv basic fibroblast growth factor(bFGF)using phage antibody library technology. Methods The library was panned with human recombinant bFGF for 4 rounds. The antigen binding activities of random clones were tested by ELISA in order to select specific antibodies, which were then examined by DNA sequence analysis. Results The positive clone selected from the 104 random clones was able to bind bFGF specifically, while not able to bind other growth factors,such as aFGF, VEGF(vascular endothelial growth factor). By competition ELISA assay we found one clone 44 could inhibit bFGF binding to FGFR1. Conclusion Seven specific human phage antibody against bFGF was obtained by phage display technique, one clone could inhibit bFGF binding to its high affinity receptor FGFR1.

Objective:To identify the allergens which can react with Chinese allergic patients in shrimp and crab ,and analysis their reaction-rates.This results would provide foundation for further research on allergen-detection and desensitization therapy.Methods:Allergen components in Metapenaeus ensis ,Macrobrachium rosenbergii and Charybdis feriata by using 46 portions of shrimp(crab) allergic patients’ serum IgE in Western blot.Results:The reactions between shrimps and allergic patients ’ serum IgE were stronger than that between crab and serum.32-38 kD Tropomysin (TM),40 kD Arginine kinase (AK),60-80 kD Hemocyanin (Hc) and 21 kD arcoplasmic calcium-binding protein(SCP) were the major allergens in shrimps.TM,AK and Hc were common major allergens among shrimps and crab and TM shared the highest reaction-rate.Compare to the results of some from American researchers , AK,Hc and SCP have higher reaction-rate when react with Chinese patients serum ,and we also found a new allergen in shrimp.Con-clusion:For Chinese patients , shrimps have higher reaction-rate than crabs and the allergens among shrimps and crabs which are roughly same.There are some differences in allergens among different human races.A new allergen with 48 kD was found in this re-search.

Objective:To clarify the contribution of endogenous bFGF, bFGF mRNA and FGFR1 to the abnormal growth and phenotypic transformation of neoplastic tumors cells.Methods:The antisense oligonucleotide primers was used to evaluate the influence of endogenous bFGF on growth of human glioma malignant cell lines SWO-38 in vitro. MTT was used to examine the variety of cells growth treated with bFGF antisense oligonucleotide primers. The methods of ELISA, in situ hybridization, immuno-hischemistry and image analysis were used to detect the expression level of bFGF, bFGF mRNA and FGFR1. The colony formation of cells in soft agar was used to assess the cloning efficiency of the cells after exposed to bFGF antisense oligo-nucleotide primers.Results:The cells multiplication, expression of bFGF mRNA and FGFR1 was inhibited by bFGF antisense oligonucleotide primers,and the cells multiplication was dose-dependent. Treated with antisense oligo-nucleotide primers, the expression of FGFR1 and secretion of bFGF were distinctly reduced, and the inhibition efficiency of cells multiplication of WSO-38 was 48% and the inhibition efficiency of colonies of SWO-38 in soft agar was 35%. The inhibition of cells multiplication can be reversed completely by external bFGF, and the reverse efficiency was 8%.Conclusion:The synthesis of bFGF mRNA and expression of bFGF can be specifically inhibited by antisense oligonucleotide, but the inhibition can be cleared up with the addition of external bFGF. The study suggested that the bFGFantisense oligonucleotide could have good effect in inhibiting of tumor under special condition.

Objective This study aims to define the effects of hypothyroidism on c-fos and c-jun mRNA expression in rat testes to provide a theoretical basis for prevention and control of iodine deficiency disorders (IDD). Methods According to body weight (200 - 240 g), 20 Wistar male rats were divided into control group and hypothyroidism group (1 ml/100 g, 0.1% propylthiouracil by intragastric administration) by digital table. There were 10 male rats in each group and body weight was observed every 3 days. After 60 days, all rats were killed. The levels of thyroid hormones [total triiodothyronine (TT3), total thyroxine (TT4), and thyroid stimulating hormone (TSH)] were measured by radioimmunoassay. The mRNA expression levels of c-fos and c-jun in testes were detected by real-time quantitative PCR. Results Compared with control groups [(298.20 ± 12.15), (344.00 ± 13.73) g], the weights of hypothyroidism groups in 30 days [(239.00 ± 15.02) g] and in 60 days [(232.67 ± 17.86) g] were significant decreased (t=7.704, 11.380, all P<0.05). The levels of TT3 [(373.32 ± 101.31) ng/L] and TT4 [(4.00 ± 0.89) × 103 ng/L] in serum of hypothyroidism group were found to be significantly decreased, whereas the level of TSH [(5.77 ± 0.89) × 103 U/L] was increased in comparison with those of the control groups [(1 000.01 ± 273.53) ng/L, (44.33 ±7.84) × 103 ng/L, (1.87 ± 0.70) × 103 U/L, t = 5.262, 12.520, 8.413, all P< 0.05]. Compared with control group (1.00 ± 0.08, 1.01 ± 0.04), the c-fos and c-jun mRNA expression (0.67 ± 0.03, 0.75 ± 0.02) of hypothyroidism group was significant decreased (t = 12.382, 13.784, all P < 0.05). Conclusion Hypothyroidism may reduce mRNA expression levels of testicular c-fos and c-jun, and then damage the reproductive system in male rats.

Objective To compare the changes in optic disc parameters after intraocular pressure (lOP) reduction between primary angle-closure glaucoma (PACG) and primary open angle glaucoma (POAG) eyes, and to determine if there is a difference of lamina eribrosa compliance between POAG and PACG. Design Prospective comparative study. Participants 36 PACG (49 eyes) and 35 POAG (49 eyes). Methods Patients underwent Heidelberg Retina Tomography (HRT Ⅱ) and Humphrey visual field test before IOP reduction. HRT and Humphrey visual field test were repeated one month after the IOP was reduced by laser, anti-glaucomatous medications or surgery treatment. Factors that affected the change in IOP were assessed including age, pretreatment IOP, IOP reduction, initial cup: disc ratio and diagnosis (POAG/PACG). Main outcome measures Changes of HRT parameters including cup area, mean cup depth, cup volume, and rim area after IOP reduction. Results The cup area, mean cup depth and cup volume decreased, and rim area in-creased significantly when the IOP was reduced (P<0.05), but there were no significant differences in the changes between PACG and POAG patients (P>0.05). Changes of these four HRT parameters were related to the amount of IOP reduction and the baseline ratio of cup to disc(P>0.05), but not related to age and pre-treatment IOP (P<0.05). Conclusions The cup became smaller and the rim area in-creased after IOP lowering with treatment in both POAG and PACG, and the magnitude of the change was similar in both groups. The lamina cribrosa compliance may not be different between POAG and PACG. (Ophthalmol CHN, 2009, 18: 264-269)
