Objective To analyze the telephone follow-up response rate and related factors in lung cancer patients thus to explore the countermeasures to increase the telephone response rate.Methods One thousand six hundred and eight post-surgery lung cancer patients were followed up by telephone interview,calculate response rates and analyze the impact factors on response rates of surgical patients. Results The lung cancer patients' overall response rate of one thousand six hundred and eight cases was 83.1%.Reservation phone type, phone number,family history of cancer are major factors affecting lung cancer patients' telephone followed up response rate(P<0.05). Conclusions Telephone follow-up of patients with lung cancer response rates is at a low level.To improve tumor response rates of follow-up and follow-up quality is a long and arduous task,requiring medical personnel continue to learn professional knowledge,summing up a reasonable follow-up methods,but also needing patients and their families to understand and cooperate.

To enhance the specificity of anti-TNF-α single chain Fv antibody (TNF-scFv) to inflamed site, we constructed a bispecific antibody BsDb that targets TNF-α and ED-B-containing fibronectin (B-FN) by covalently linking TNF-scFv and the anti-ED-B scFv L19 at the gene level via a flexible peptide linker deriving from human serum albumin. BsDb was successfully secreted from Pichia pastoris as functional protein, identified by immunoblotting, and purified to homogeneity with affinity chromatography. BsDb retained the immunoreactivity of its original antibodies TNF-scFv and L19, and showed a marked gain in antigen-binding affinity and in TNF-α-neutralizing ability, when compared to TNF-scFv and L19 that were produced in Escherichia coli. In the adjuvant-induced arthritis (AIA) mice model, BsDb showed selective accumulation and retention in the inflamed paws but rapid clearance from blood, resulting in high arthritic paw to blood ratios. These data indicate that BsDb is endowed with high specificity to inflamed site and low toxicity to normal tissues and holds great potential for in vivo application for the targeted therapy of RA and other chronic inflammatory diseases.

In order to enhance the specificity of TNF-α monoclonal antibody to inflamed site, a bispecific antibody BsDb that targets TNF-α and the extra-domain B (ED-B) of fibronectin (FN) was constructed by covalently linking the anti-TNF-α single chain Fv antibody (TNF-scFv) and the anti-ED-B scFv L19 via a flexible peptide linker deriving from human serum albumin (HSA). ED-B is an antigen specifically expressed at the inflamed site. BsDb is expressed in E. coli, identified by immunoblot, and purified with affinity chromatography. This was followed by further examination of its bioactivities and pharmacokinetics. We demonstrated that BsDb retained the immunoreactivity of its original antibodies as it could simultaneously bind to TNF-α and ED-B and neutralize the biological action of TNF-α. In the collagen-induced arthritis mice model, BsDb selectively accumulate in the inflamed joint with a maximal uptake of (12.2 ± 1.50)% ID/g in a single inflamed paw and retain in the inflamed paw for at least 72 h. In contrast, BsDb showed a short serum half-life of (0.50 ± 0.05) h and a rapid clearance from normal tissues. The findings reported herein indicate that BsDb has good specificity to the inflamed site and low toxicity to normal tissues. BsDb is therefore likely to have greater clinical applications in the treatment of rheumatoid arthritis and other autoimmune diseases. This laid a stable basis for its preclinical study.

Objective To investigate serum total prostate special antigen(tPSA),complexed prostate special antigen(cPSA)and cPSA/tPSA ratio(C/T) in the differential diagnosis of benign prostate hyperplasia(BPH)and prostate cancer(PCa).Methods A total of 184 serum samples from hospital outpatient and inpatient were collected from May 2009 to December 2015,and which were divided into three groups including other diseases 68 patients,benign prostate hyperplasia(BPH group)80 patients,prostate cancer (PCa group)36 patients.Chemiluminescence immunoassay was used to detect the concentration of tPSA and cPSA,and the C/T ratio were calculated in the study.Results The tPSA,ePSA levels and C/T ratio were significant different from patients with PCa,BPH and other diseases group(P＜0.01).Compared with BPH group(r=0.661),the tPSA and cPSA levels have a higher relativity in PCa group(cPSA=0.708 × tPSA-0.219,r=0.956).While when tPSA level ranges 4.0-10.0 ng/mL),no significant difference of tPSA,cPSA levels and C/T ratio were found in these 3 groups(P＞0.05).Conclusion Combined detection of serum tPSA,cPSA and C/T,making importance in the differential diagnosis of BPH and PCa.

Objective To investigate demographic factors implicated in the functional maturation of autologous arteriovenous fistula in a population of patients with end-stage renal disease. Methods The data of 335 consecutive patients with end-stage renal disease who were performed autologous arteriovenous fistula from January 2010 to December 2015 were analyzed retrospectively. The parameters affecting autologous arteriovenous fistula functional maturation were screened. Results Overall arteriovenous fistula functional maturation rate was 78.14%(218/279). The arteriovenous fistula functional maturation rate was 68.33%(82/120) in diabetes and 85.54%(136/159) in non-diabetes, and there was significant difference (χ2=11.844, P<0.01). The arteriovenous fistula functional maturation rate was 62.26%(33/53) in hypoproteinemia and 81.86%(185/226) in non-hypoproteinemia, and there was significant difference (χ2=9.648, P<0.01). Diabetes and hypoproteinemia were the risk factors to promote functional maturation (OR=6.003, 8.476). The arteriovenous fistula functional maturation rate was 87.10%(81/93) in calcium channel blockers using and 73.66%(137/186) in non-calcium channel blockers using, and there was significant difference (χ2=6.556, P<0.05). Calcium channel blockers was the protective factor for promoting functional maturation (OR=0.086). Conclusions Diabetes and hypoproteinemia are found to be associated with functional non-maturation, while calcium channel-blocker agents are associated with better functional maturation.

Objective To evaluate the effect of pepliteal artery endovascular angioplasty for the treatment of diabetic foot. Methods 65 cases (69 limbs) of diabetic foot were treated by long bloon endovascular angioplasty. Results No death occured. 60 cases (64 limbs) were successfully treated and 5 cases (5 limbs) failed. The imme-diately success rate was 92.75%. The pain relieved, the temperature was improved and the ankle brachial index (ABI) was up to 0.84±0.11. Anterior tibial artery or posterior tibial artery of 39 limbs could be touched. 21 limbs were cured by debride and change dressings. 10 limbs were cured after the gangrene was ablated. 6 limbs were cured after the gangrene was debrided. 22 limbs were cured after toe amputation. Half of the foot was amputated. No limb was amputated. Every month was further consulted by Doppler and the rate of follow upwas 100%. 6 limbs of 6 cases were reobliterated (1,1,2,2 cases occurred after 1,6,12,18 month respectively.) and treated by endovascular an-gioplasty again. Conclusion Endovascular angioplasty below the knees for the treatment of diabetic foot is an effec-tive method for the limbs saving, with minimal invasive, safety, less complication and retreatment. It can be used as a first choice for the artery obliteration of diabetic foots.

Objective To explore the clinical characteristics in patients with histiocytic necrotizing lymphadenitis (also called Kikuchi-Fujimoto' s disease,KD) and meningitis.Methods We reported a patient who developed meningitis preceding the other presentations of KD with abnormal serum autoimmune phenomena,and systematically reviewed 19 cases of KD with meningitis that had been reported worldwide,and analyzed the clinical parameters and treatments.Results The present case was a 25-year-old female subject with serum antinuclear factor antibody and anti-ribonucleoprotein antibody positive.The patient recovered after treatment with steroid and no recurrence was appeared.Among the 19 patients,the average age was 20.2 years,sex ratio was 10:9 (10 female:9 male),7 patients had abnormal serum autoimmune phenomena,7 patients'initial symptom was meningitis and 5 patients were administrated with steroid.Conclusions The onset age in KD with meningitis is earlier than the common KD,and sex ratio in KD with meningitis is close to 1∶ 1.A definitive diagnosis of the disease is determined by a lymph node biopsy at present.

Objective To evaluate whether changes in neonatal intensive care have improved outcomes for extremely low birth weight (ELBW) infants in neonatal intensive care unit (NICU). Methods A prospective phase-lag cohort study was performed in a tertiary level NICU. A meticulous nursing strategy based on neonatal individual developmental care assessment program theory and feasible ELBW minimization stimulus was developed. Conventional care was applied in 2013 (period Ⅰ) and gently caring was applied in 2014 (period Ⅱ). The outcomes of ELBW between these 2 periods were compared. Results During these two periods, thirty-seven infants were included in period Ⅰ and 41 infants in period Ⅱ. In periodⅠ46.0%(17/37) of the infants needed oxygen for at least 28 days, but in period Ⅱ it decreased to 24.4%(10/41), there was significant difference (χ2=3.990, P=0.046). The rate of breastfeeding increased from 27.0%(10/37) in periodⅠto 61.0%(25/41) in period Ⅱ, there was significant difference (χ2=9.061, P=0.003). There was no significant difference in the mortality rate and chronic lung disease (P>0.05). The incidence of intracranial hemorrhage decreased from 21.6%(8/37) to 4.9%(2/41), there was significant difference(P=0.041). Conclusions Gently caring may have resulted in less intracranial hemorrhage and improve breastfeeding rate. Parents are satisfied with gentle care and in light of these findings, gentle care deserves further exploration.

AIM:To explore the influences of semaphorin 3A (Sema 3A) on hydrogen peroxide (H2O2)-induced injury in human umbilical vein endothelial cells (HUVECs).METHODS:Sema 3A over-expression vectors were constructed and transfected into the HUVECs by Lipofectamine 2000, and the over-expression effect was verified by qPCR and Western blot.The HUVECs in different groups were treated with or without 200 μmol/L H2O2 for 4 h.The levels of inflammatory cytokines were measured by qPCR.The levels of lactic dehydrogenase (LDH), superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by corresponding colorimetry.The cell viability was measured by MTT assay.The cell apoptosis was analyzed by flow cytometry.The levels of apoptosis-related proteins cleaved caspase-3 and Bcl-2 were determined by Western blot.RESULTS:H2O2 induced inflammatory cytokine secretion, increased the levels of LDH and MDA, decreased SOD activity and cell viability, and increased cell apoptosis in the HUVECs.Over-expression of Sema 3A enhanced the above processes.No injury effect of Sema 3A over-expression on HUVECs without H2O2 treatment was observed, indicating that the injury effects of Sema 3A on HUVECs depended on H2O2.CONCLUSION:Sema 3A markedly enhances H2O2-induced injury in the HUVECs, which depends on H2O2.Sema 3A may promote oxidative stress-caused endothelial cell injury.

Objective To investigate toxicity and teratogenic effect of Microula seed oil on embryo of rat.Methods 150 mature Wistar rats (100 females, 50 males) were selected with female∶ male = 2∶1 cage match. During the daily morning examination the sperm was discovered in the vagina as the zero day for conception.100 pregnant rats were randomly divided into 5 groups (n=20 in each group): treatment group (included 3 groups: to give Microula seed oil 2.5 g /kg, 5.0 g /kg, 10.0 g /kg body weight, ig, respectively), cyclophosphamide group(7 mg/ kg body weight, sc) and the edible oil group (to give dose, such as volume as Microula seed oil, ig). From the 7th day of pregnancy, the treatment group, the edible oil group were given intervention once a day for 10 days. From the 11th day of pregnancy cyclophosphamide group was given cyclophosphamide as intervention once a day, for 3 days. On the 20th day the pregnant rats were killed.Results The body weight of pregnant rats and the rate of live births were significantly higher in the Microula seed oil dose group than in the cyclophosphamide group (P<0.01), stillbirth rate and birth rate of absorption was significantly lower in the Microula seed oil dose group than in the cyclophosphamide group (P<0.01), and no significant difference from the edible oil group (P> 0.05); the fetal rat, body weight, body length, tail length in all groups of Microula seed oil was no significant difference from the edible oil group (P> 0.05). There was no malformation in appearance, viscera, bones in the treatment group and the edible oil group while there were 112 fetal rats with deformity in 140 in the cyclophosphamide group.Conclusion Microula seed oil at doses of 2.5 g /kg, 5.0 g /kg, 10.0 g /kg body weight had no significant role in the toxicity and teratogenicity on embryos of pregnant rats.
