Objective To investigate the effect of hyperbaric oxygen therapy on awareness,sports,activities of daily living in the rehabilitation of patients with early traumatic brain injury,and to observe the curative effect. Methods 80 patients with severe traumatic brain injury whose disease course within 1 months were randomly divided into observation group and control group,40 cases in each group.The control group received conventional drug therapy in neurosurgery and rehabilitation training.The observation group received hyperbaric oxygen therapy on the basis of the control group.Before treatment and one month after treatment,consciousness (GCS score),motor function (FMA score),activities of daily living (MBI score),and the clinical efficacy were compared between two groups.Results The scores of FMA,MBI and GCS in the control group were (7.81 ±2.27),(26.05 ±22.58),(15.25 ±12.14), which in the observation group were (7.78 ±2.32),(27.01 ±23.60),(14.37 ±12.54),and the differences were not significant (P >0.05).After 1 month of treatment,the scores of the control group were (9.44 ±2.76),(43.10 ± 31.54),(42.75 ±16.58),which of the observation group were (10.67 ±2.48),(56.98 ±29.68),(52.76 ± 17.23).The scores in the two groups were improved,the observation group increased more and the clinical efficacy was more obvious,there were significant differences between the two groups (P =0.039,0.046,0.009).Conclusion Hyperbaric oxygen plays an active role in early rehabilitation of patients with traumatic brain injury,it can improve consciousness,motor function and activities of daily living,and can improve the prognosis.

Objective We reported previously that single nucleotide polymorphisms SNP) + 11G ＞ A in intron 3 of the human urate transporter 1 (hURAT1) gene are associated with hyperuncaemia in Han Chinese.The aim of the present study was to evaluate the effect of the variants on hURAT1 function.Methods The wild-type,mutant-type hURAT1 and exon 5-null hURAT1 were constructed,and respectively microinjected into the zebrafish embryo yolks.The subcellular localization of different genotypes of hURAT1 was detected by confocal laser scanning microscope.Results Compared with wild type,the mutant recombinant plasmid transcribed two types of mRNA spliceosome,the wild type and the exon 5-null type.The hURAT1 wild type protein was prominent localized on cell membrane,while the mutant type and exon 5-null hURAT1 proteins were distributed uniform in the cytoplasm but not on the cell membrane.Conclusion The hURAT1 variant + 11 G ＞ A resulted in an alternative splicing of hURAT1 mRNA-exon 5-null type.Its protein product exhibited a different subcellular localization compared with that of wild type.

Objective To explore the necessity and effectiveness of type-based acupuncture treatment for cervical spondylosis. Method Two hundred and forty patients with clinically common cervical spondylosis, cervical spondylotic radiculopathy or cervical spondylotic vertebral arteriopathy, 80 cases each type, were enrolled. Every type of patients was randomly allocated to observation and conventional groups. The observation group (120 patients) received type-based acupuncture treatment. Cervical spondylosis was treated by syndrome differentiation; cervical spondylotic radiculopathy, from the spleen and stomach; cervical spondylotic vertebral arteriopathy, with nape five-needle acupuncture. Every type of the conventional group (120 patients) received the same therapeutic method (conventional selection of acupoints). Before and after five and ten sessions of treatment, cervical spondylosis and cervical spondylotic radiculopathy were scored using the CSAS and the VAPS and cervical spondylotic vertebral arteriopathy was scored using the ESCV. The overall therapeutic effects were evaluated after ten treatments. Result Of the patients with cervical spondylosis, there were statistically significant pre-/post-treatment differences in the CSAS and VAPS scores in the two groups (P<0.05, P<0.01) but no statistically significant differences in the scores between the groups (P>0.05). Of the patients with cervical spondylotic radiculopathy, there were statistically significant differences in the CSAS and VAPS scores in the two groups after five treatments compared with before (P<0.05) but no statistically significant differences in the scores between the groups (P>0.05);after ten treatments there were statistically significant differences in the scores in the two groups compared with before (P<0.01) and also between the groups (P<0.05). Of the patients with cervical spondylotic vertebral arteriopathy, there was a statistically significant difference in the ESCV score in the observation group after five treatments compared with before (P<0.01);the score also decreased in the conventional group (P<0.05);there was a statistically significant difference between the groups (P<0.05);after ten treatments there was a statistically significant difference in the ESCV score in the two groups compared with before (P<0.01) and also between the groups (P<0.05). After ten treatments, the cure and marked efficacy rate and the total efficacy rate were 76.6%and 92.8%, respectively, in the observation group and 54.2%and 86.0%, respectively, in the conventional group. There was a statistically significant difference in the cure and marked efficacy rate between the two groups (P<0.01). Conclusion Type-based acupuncture can markedly improve the clinical therapeutic effect on cervical spondylosis.

Objective To study the effects of different oxytocin doses on neonatal pathologic jaundice.Methods A total of 386 newborn infants with normal term of labor were selected from the full-term pregnant women who were admitted to Jiaxing Maternal and Child Health Care Hospital from August 2014 to September 2015 were divided into low dose group (2.5 ~5.0U,n=96), middle dose group (5.0 ~7.5U,n=96), high dose group (7.5~10.0U,n=96) and control group (n=98) according to the different dosage of oxytocin.Total labor time, neonatal gender, neonatal weight and maternal age, as well as the day of birth within seven days of skin side of the bile values were recorded.The probability of each group of neonatal patients with pathological jaundice and the relationship with oxytocin doses were studied.Results The incidence of neonatal pathologic jaundice was 3.23%in the low dose group, 6.67%in the middle dose group, 29.73%in the high dose group and 3.16%in the control group.The differences among low dose group, middle dose group and control group were not significan.Compared with high dose group, the incidence of neonatal pathologic jaundice in low dose group, middle dose group, and the control group were all lower(P<0.05).Conclusion Oxytocin less than 7.5U in labor has no significant effect on neonatal pathologic jaundice, >7.5U can promote pathologic jaundice.

Compared with normal tissues and cells, the tumor microenvironment has significant differences. For example, glutathione-related metabolic enzymes and reactive oxygen species are highly expressed in different subcellular structures, resulting in an unbalanced redox state. Aiming at the specific redox state in tumor tissues and cells, a series of small molecule prodrug self-assembled nanoparticles can be designed and connected by intelligent response linkers including disulfide bonds, sulfide bonds, and selenium bonds, thioketal bonds, etc. The in vitro and in vivo efficiency and metabolic mode of these nanoparticles are related to the type of linker. This review will summarize the tumor redox microenvironment, the design of intelligent responsive small molecule prodrug nanoparticles, and the metabolic pathways of small molecule prodrug nanoparticles with different connecting linkers and their relationship with drug efficacy.

Objective To evaluate the clinical efficacy and safety of treatment of non-small cell lung cancer (NSCLC) with autologous and half consistency allograft cytokines induced killer cells combined with chemotherapy. Methods We selected 42 patients with NSCLC patients as the research object. According to the group matching principle, the cases were divided into three groups: autologous CIK cells combination chemotherapy group, half consistency allograft CIK cells combination chemotherapy group, pure chemotherapy group. The autologous and allograft CIK cellular immune therapy of security, flow cytometric analysis technique (FCM) comparisons between before and after the treatment group infusion in vivo T lymphocyte subsets changes, and three treatment group clinical short-term curative effect were used in the comparison.Results FCM detection results show that CIK cell infusion after, CD+3, CD+4 / CD+8 ratio, NK cells (CD+3 CD+56)and CIK cells (CD+3 CD+56) ratio obviously higher than before treatment, autologous infusion before treatment,respectively (47.2±10.1) %, 1.0±0.1, (15.1±2.7) %, (0.7±0.2) %. After treatment respectively (58.8±12.3) %,1.3±0.2, (24.6±7.1) %, (3.8±2.2) %; Allograft infusion before treatment for (49.4±11.4) %, 0.9±0.2, (14.8±3.2) %, (0.9±0.3) % for after treatment (57.3±9.2) %, 1.4±0.3, (25.4±6.7) %, (4.3 ± 2.6) % (t = 22, 20, 19,P ＜ 0.05), and the pure chemotherapy group before and after the treatment T lymphocyte subsets level has not seen the obvious change. Clinical short-term curative effect comparison, autologous and allograft CIK cell therapy group objective efficient and disease control rates are slightly higher than the pure chemotherapy group, but the difference was not statistically significant. Respectively 21.4 %, 57.1%, and 35.7 %, 28.6 %,64.3 %, 71.4 % (x2=38.85, x2=41.24, P ＞ 0.05). Conclusion Autologous or half consistency allograft CIK cellular immune therapy is good safety and low toxicity, have certain short-term curative effect, which can effectively slowed tumor recurrence, is a worthy of popularizing clinically tumor adjuvant treatment mode.

Objective To investigate the value of integrin αvβ3 targeted microSPECT/CT imaging with 99 Tcm-3P4-RGD2 as a radiotracer in tumor anti-angiogenesis therapy .Methods Animal models bearing glioma and prostate cancer xenografts were established by subcutaneously injecting tumor cells U87MG and PC-3 in nude mice.Anti-angiogensis therapy with Avastin was administered via intraperitoneal injection when the tumor diameter reached 6 to 7 mm while saline was served as control group . MicroSPECT/CT imaging was performed with 99 Tcm-3P4-RGD2 as radiotracer one day before and 3, 5, 10, 15 days after Avastin administration .Tumor volume and tumor uptake of 99 Tcm-3P4-RGD2 , expressed as percentage of injected dose (%ID) or %ID per gram (%ID/g) were measured and calculated based on microSPECT/CT.Mice basic condition was monitored and tumor xenograft was harvested in one tumor bearing nude mouse after its sacrifice at each imaging time point .Results Tumor volume of U87MG glioma in the administration group was significantly smaller than that of non-administration control group at 10 d after Avastin adminstration ( t=5.81, P<0.05), while no significance was observed between the administration group and its control group of PC-3 tumor (P >0.05).The uptake of 99Tcm-3P4-RGD2 (%ID/g) in U87MG group was higher than that in PC-3 group before Avastin administration ( t=10.48, P<0.05), and it decreased to a value less than control ( t =3.26, P <0.05) at 3 d after Avastin administration and continually reduced at longer time after administration .PC-3 tumor had less uptake of 99 Tcm-3P4-RGD2 in both Avastin administration group and its control group .The pathologic results revealed on that the decrease of tumor integrin β3 expression in U87MG treatment group was mainly on the endothelial cells of the neovessel .Linear relationship was verified between tumor uptake (%ID/g ) and integrin β3 expression (y=0.499 1x-0.243 8, R2 =0.811 7).Conclusions Complete inhibition of integrin is demonstrated early after Avastin administration .99 Tcm-3P4-RGD2 microSPECT/CT imaging, assessing the expression level of integrin αvβ3 level by quantification of tumor uptake of 99 Tcm-3P4-RGD2 , is probably an important method to reflect the early therapeutic effect of tumor anti -angiogensis .

Objective To study the effect of the recombinant Lentivirus containing calcitonin gene related peptide (CGRP) gene on cells biological activity and differentiation of rat bone marrow stem cells(MSCs).Methods Rat MSCs were isolated and cultured by granulocytes adherent.MSCs were transfected with Lenti-EGFP CGRP(MSCsCGRP+/+ group),While MSCs were transfected with Lenti-EGFP as control group.Cell transfection rate was detected by flow cytometry,protein secretion in the above-mentioned MSCsCGRP+ + supernatant was detected using ELISA method.Cells surface markers weare detected by flow cytometry and immunohistochemistry.Trypan blue was used to examin the survive rate,β galactosidase staining was used to examin aging of MSCs transfection,and MTT was used to examine cell vitality.Results At first day after transfecting with Lenti-EGFP-CGRP,fluorescence was not observed by fluorescence microscope,but a small amount of CGRP protein was detected by ELISA in MSCsCGRP+/+ group,at 3 days and 4 days after transfecting with MSCs,strong fluorescence was observed by fluorescence microscope (the cell transfection rates were 77.87％ and 79.58％).The CGRP expression was significantly higher in MSCsCGRP+ + group than in control group [(19.53±0.50) pg/ml vs.(3.12±0.00) pg/ml,t=48.964,P＜0.01].At three days after transfection with MSCs,CD29 and CD90 expression were significantly higher,as compared with control group,CD31 expression was increased in MSCsCGRP+ /+ group.Seven days after transfection with MSCs,CD31 expression was significantly increased in MSCsCGRP+ + group,vWF expression was significantly increased in MSCsCGRP+ + group after MSCs were transfected with LentiEGFP CGRP for 14 days,but a SMA expression was decreased in MSCsCGRP+ +group.At 3 days and 7 days after transfection with Lenti-EGFP-CGRP,the proliferation,survive and aging showed no difference in MSCsCGRP+/+group and in control group (the proliferation of cell:t=0.253,0.290the survive of cell t=-0.307,0.690,all P＞0.05).At 14 days after transfection with Lenti-EGFP-CGRP,aging of cell were decreased in MSCsCGRP+ + group as compared with control group (t=2.446,P＜ 0.05).Conclusions After MSCs are transfected with Lenti EGFP-CGRP,biological characteristics of MSCs has no significant effects,there is still proliferation and differentiation activity.Cell secretion of CGRP can promote the endothelial cell differentiation,and inhibit the differentiation to smooth muscle cells.The CGRP modification of MSCs may play a role in the regulation of angiogenesis.

Objective To investigate the clinical value of evaluation of fetal cardiac function in congenital heart disease by brain natriuretic peptide (BNP) and velocity vector imaging (VVI). Methods Fetuses who came from Shenzhen Maternity & Child healthcare Hospital were divided into the congenital heart disease group and the control group. At the same time we collected amniotic fluid and assayed BNP concentration. Using the VVI software, the velocity, strain and strain rate of the global and segmental of the left ventricle were measured. Comparison and correlation were made between the two groups. Results There was significantly difference of BNP concentrations in amniotic fluid between two groups. The gestational age had significant positive correlation with BNP concentrations in disease group. The comparison of global velocity, strain and strain rate of left ventricle between the two groups showed significant differences. All of the left ventricular dynamic parameters in disease group were lower than those of the control group. Conclusions Compared with the control group, the disease group had a high level of BNP in amniotic fluid and a lower level of dynamic parameters of left ventricular. There was a positive correlation between BNP concentration and gestational age in disease group. So we can conclude that theBNP concentration can be a biological parameter for evaluating the latent impairments of fetal cardiac function.

Objective To explore the efficacy and safety of endoscopic balloon dilatation of small bowel stricture in Crohn′s disease with single balloon enteroscopy (SBE).Methods Seven Crohn′s disease patients (four males and three females with a mean age of 37 years) were underwent 10 times dilatation.Before performance,Crohn′s disease with varying degrees of intestinal obstruction was confirmed by image and pathological examinations.There were 8 severe strictures,6 strictures in jejunum.The dilatation was performed step by step with controlled radial expansiondilator (CRE) balloon.After dilatation,the scope could reach the further small bowel was taken as a standard.Results The overall suecess rate was 8 of 10.The average diameter of intestinal stricture was expanded from (4.1 ± 2.5) mm before therapy to (10.2 ±1.5) mm (P＜0.01),and the average distance of the further small bowel that the scope reached was 62 cm.Two patients underwent twice and three times of dilatation.After the performance,all patients′ symptoms of abdominal pain and obstruction relieved obviously and there were no severe complication of bleeding or perforation.After the performance,the average follow-up time was 14 months,two patients were treated by surgery and the other two underwent dilatation treatment again because of the recurrence of symptoms.The median symptom-free time was 15 months and 70％ of patients were without symptom recurrence in one year.Conclusion Endoscopic balloon dilatation of small bowel stricture with SBE is a new technology of endoscopic treatment,which is safe and effective in the treatment of Crohn's diseasecomplicated with intestinal obstruction.
