Objective To explore the risk factors and outcomes associated with pulmonary hemorrhage in very low and extremely low birth weight infants.Methods Retrospective analysis were performed to predict risk factors for pulmonary hemorrhage in very low and extremely low birth weight infants (birth weight less than 1200g) admitted to NICU of Shengjing Hospital from Jan.2010 to Dec.2015.Infants at similar birth weight without pulmonary hemorrhage were as controls.We compared the characteristics of both maternal and infants.Multivariable Logistic regression models were derived to predict pulmonary hemorrhage.Short outcomes of the infants were assessed.Results Of the 435 neonates,71 developed pulmonary hemorrhage (pulmonary hemorrhage group),364 were as controls (control group).Gestational age[(28.2±1.7)week],birth weight[(936±192)g] in pulmonary hemorrhage group were significantly lower than those in control group[(29.5±2.1)week,(1033±134)g,t=4.776,5.145,P<0.01].Neonatal respiratory distress syndrome(RDS)(76.1%),pulmonary surfactant (PS)use(PS use≥2 courses)[76.1%(9.9%)],patent ductus arteriosus (PDA)(66.2%)were significantly higher than those in control group[41.2%,30.8%(4.1%),38.7%;χ2=33.457,28.970(4.074),32.798,P<0.05].Antenatal corticosteroids utility ratio (21.1%)was lower than that in the control group (41.2%;t=10.177,P< 0.001).Multiple factors Logistic stepwise regression analysis showed that RDS (OR=3.739,95%CI 1.383-10.113,P<0.05 ),PDA (OR=2.206,95%CI 1.205-4.093,P<0.05),and 5 minutes Apgar score <7(OR=2.851,95%CI 1.191-6.828) were independent risk factors of pulmonary hemorrhage,and higher birth weight (OR=0.998,95%CI 0.996-1.000,P<0.05) and the use of antenatal corticosteroids (OR=0.432,95%CI 0.224-0.834,P<0.05) were the protection factors in pulmonary hemorrhage.In pulmonary hemorrhage group,the incidence of intracranial hemorrhage,retinopathy of prematurity and severe bronchopulmonary dysplasia(16.9%,12.7% and 18.3%) were significantly higher than those in control group (5.8%,4.4% and 2.2%;χ2=36.824,7.520 and 33.568,P<0.01);Compared to control group,the mortality in pulmonary hemorrhage group was higher (49.3% vs.14.0%;χ2=46.634,P<0.01).Conclusion Pulmonary hemorrhage in very low and extremely low birth weight infants is associated with multiple factors.Prevention of premature birth and prenatal corticosteroids treatment can help prevent the occurrence of pulmonary hemorrhage.The incidences of poor outcomes are higher in newborns with pulmonary hemorrhage.

Background and purpose:To investigate the induction of apoptosis by epigallocatechin-3-gallate(EGCG) in xenograft nude mice with human gastric cancer cells and its molecular mechanism. Methods:Human gastric cancer cells were planted into nude mice in order to establish the cancer model, the different dosages of EGCG were injected intraperitoneally in the nude mice. After treatment, flow cytometry (FCM) was used to detect the apoptosis of implanted tumor cells. Immunohistochemical staining was used to detect the expression of apoptosis-related genes like Bal-2 and Bax in implanted tumor.Results:EGCG significantly inhibited tumor growth after being injecting intraperitoneally in the nude mice. The apoptotic cells in implanted tumor could be detected by flow cytometry with PI staining. The expressions of Bax、Caspase-3 were upregulated and Bcl-2 expression was downregulated in implanted tumor.Conclusions:EGCG could significantly inhibit tumor growth in xenograft nude mice with human gastric cancer cells through inducing apoptosis. The down-regulation of Bcl-2 expression and up-regulation of Bax expression observed could result in the activation of Caspase-3, the pathway might account for the induction of apoptosis.

Objective To investigate the effectiveness of endoscopy and enteral nutrition (EN) in the treatment of acute biliary pancreatitis (ABP) in elderly patients and its impact on prognosis.Methods Eighty-four elderly patients with ABP were randomly divided into two groups,including 42 cases of combination treatment group,42 cases of routine treatment group.The routine treatment group was managed with normal comprehensive treatment,and in combination treatment group,patients were treated with additional endoscopic retrograde cholangiopancreatography (ERCP),endoscopic sphincterotomy (EST) and endoscopic naso-biliary (ENBD) drainage and EN.The clinical symptoms,serum inflammatory cytokines,complications and prognosis were compared.Results The CRP,TNF-α,IL-2,and serum amylase,glucose,AST after treatment were significantly lowered than those before treatment (P ＜ 0.05).In addition,the levels of CRP,TNF-α,IL-2,and serum amylase,glucose,AST,ALB in combination treatment group were significantly lower than those in routine treatment group (P ＜ 0.05).The time to abdominal pain cessation,time to fever cessation,hospital stay in combination treatment group were (4.6± 1.3),(3.7± 1.3),(13.5± 2.7) d,which were significantly lower than those in routine treatment group [(6.1 ± 1.3),(5.5 ± 2.1),(18.1 ± 3.8) d,P ＜ 0.05].The APACHE Ⅱ score of combination group after treatment was (7.l ± 1.8) point,which was significantly lower than that in routine treatment group [(9.2 ± 2.6) point,t =3.41,P ＜ 0.05)].The incidence rates of ARF,ARDS,peri-pancreatic infection and abdominal hemorrhage,in combination group were 7.1％,4.8％,4.8％,4.8％,respectively,which were significantly lower than those in routine treatment group (23.8％,19.1％,21.4 ％,19.1％,P＜0.05).The mortality in combiration group was 4.8％,which was lower than 16.7％ in routine treatment group with no statistical significant.Conclusions It is a safe and effective to treat elderly ABP patients with endoscopy combined with EN,which can significantly reduce complications and mortality.

AIM: To compare the impacts of adriamycin(ADM) intermittent and continuous heat infusion on respiration, heart rate and temperature of the rabbit as well as the concentration of ADM in VX-2 tumor for the verification of the safety and effectiveness of intermittent heat infusion through VX-2 transplanted tumor model in rabbit liver.METHODS: VX-2 tumor models were established respectively in the thighs of 30 New Zealand rabbits. All 30 rabbits were randomly allocated into three groups with 10 rabbits each. After catheterizing into femoral artery, which was demonstrated as the supply artery of tumors by digital subtraction angiography(DSA), animals in three groups were infused with 100 mL saline at normal temperature and ADM, 100 mL saline at 60 ℃ and ADM continuously and 100 mL saline at 60 ℃ and ADM intermittently respectively. During infusion, the 43 ℃ to 45 ℃ lasting time in the tumor tissues of the two 60 ℃ groups was measured. After infusion, the respiration(time/minute), heart rate(beats/minute) and temperature(℃ )of the rabbits in each group as well as the concentrations of ADM in tumor tissue were measured immediately.RESULTS: The concentration of ADM was (7. 1 ± 2.2) mg/L in normal temperature infusion group, (17.2 ± 1.6) mg/L in 60 ℃ continuous infusion group and(16.5 ±3.4) in 60 ℃ intermittent infusion group. There were significant differences among three groups( F = 48.95, P = 0. 000), but there was no significant difference between 60 ℃ intermittent infusion group and 60 ℃ continuous infusion group( P ＞ 0. 05). 43℃ to 45 ℃ lasting time was(22.5 ±1.4) minutes in 60 ℃continuous infusion and (24.3±2.4)minutes in 60 ℃intermittent infusion group( F =4.20, P ＞ 0.05) . There were significant differences among three groups in respiration, heart rate and temperature( F = 14. 58, 33.07, 10.00, P ＜ 0.01), but there was no significant difference in the respiration, heart rate and temperature between 60℃ intermittent infusion and normal temperature infusion group ( P ＞ 0. 05).CONCLUSION: Intermittent thermochemotherapy is a more effective and safe interventional thermochemotherapy method compared with continuous heat infusion.

Anti-angiogenesis mechanism plays a vital role in tumor targeting immunotherapy. Based on the amino acid sequence of an anti-VEGFR-2 scFv-Fc fusion antibody (AK404R-Fc), this article is aimed to generate an anti-VEGFR-2 human IgG1-like full length antibody (Mab-04). Firstly, the light chain (L-chain) and heavy chain (H-chain) were obtained by overlap PCR and then linked to eukaryotic expression vector pcDNA3.1, separately. The recombinant plasmids (pcDNA3.1-L-chain and pcDNA3.1-H-chain) were then co-transfected into CHO-k cells using liposome transient transfection. Subsequently, Mab-04 antibody was expressed and purified by Protein A affinity chromatography. Western blotting was applied to identify the expression of Mab-04 and its affinity was detected by ELISA assay. DNA sequencing revealed the successful construction of recombinant plasmids and Western blotting assay proved the successful expression of full-length antibody (1 microg x mL(-1)). Finally, ELISA assay illustrated that the binding of the antibody to its antigen was in a concentration-dependent manner (IC50: 50 nmol x L(-1)). These outcomes above indicated that Mab-04 was successfully expressed and assembled, which laid the foundation for further preparation and antineoplastic activity study.

Objective: To observe the clinical efficacy of filiform fire-needling plus continuous passive motion (CPM) therapy for frozen shoulder. Methods: A total of 72 patients were randomized into an observation group and a control group by the random number table method, with 36 cases in each group. Patients in the control group received celecoxib capsule plus CPM, while those in the observation group received filiform fire-needling plus CPM. The whole course of treatment lasted for 2 weeks in both groups. The visual analog scale (VAS), Constant-Murley score (CMS) and range of motion of shoulder joint were measured for therapeutic efficacy evaluation. Results: The total effective rate was 91.7％ in the observation group, higher than 72.2％ in the control group, and the between-group comparison showed statistical significance (P<0.05). After treatment, the VAS scores in the two groups dropped significantly, the CMS as well as the range of motion including abduction, forward flexion and extension were all increased significantly, and the intra-group comparisons showed statistical significance (all P<0.05). The betweengroup comparisons showed the improvements in these items in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Filiform fire-needling plus CPM can produce more significant efficacy than celecoxib capsule plus CPM for frozen shoulder; it can alleviate pain, improve shoulder function and restore joint range of motion in such patients.

Diabetic retinopathy(DR), one of the most common retinal vascular disease, is one of the causes of blindness for people over the age of 50.In the early stage of DR, microvascular cells are damaged, expand, start to leak, form micro hemangioma, then show occlusion, and non-perfusion area come into being, eventually form new blood vessels because of ischemia and hypoxia of retina.Illness develop into proliferative diabetic retinopathy(PDR).With the aggravation of the disease, PDR can cause the formation of fibrovascular membrane, the more serious fibrillation of epiretinal membrane, resulting in traction retinal detachment(tRD).Present studies suggest that aquaporins, the essential component of new blood vessels, including aquaporin 1 and aquaporin 4, play a significant pole in the development of diabetic retinopathy, causing the destruction of blood retinal barrier, inducing retinal edema, even macular edema, and participating in the formation of retinal angiogenesis.

Myopia is the highest incidence of eye disease in society, it threated people`s eye health seriously.At present, many researchers measure the structural changes of retina which caused by the extension of eye axial due to the refractive error according to the optical coherence tomography(OCT).Besides, multifocal electroretinography(mf-ERG) was used to detect the function of retina in myopia.Global flash mf-ERG can evaluate the function of retina including both outer and inner retina.Some researchers focus on the correlation between structural and functional changes in myopia using OCT and mf-ERG.More researches are needed to clarify the structural and functional changes in myopia.
