Objective To explore the effects of donor dendritic cells(DC)treated with Ad-IL- 12p35siRNA on the survival of allogragft recipients.Methods The recombinant adenoviral vectors carrying IL-12p35siRNA and HKsiRNA were transfected into bone marrow derived DC of BALB/C murine.C57BL/6 recipients were infused with DG(Ad-IL-12p35siRNA DC,Ad-HKsiRNA DC and control DC)from BALB/C donors 7 days before cardiac allograft,the survival time of murine and the change of T_H 1 and T_H2(IL-2,IL-4,IL-10 and IFN-?)cytokine were observed.Results The survival time of p35 group(20.17?2.71)days was longer than that of control group(7.81?1.61)days and HK group(7.17?1.60)days.The concentration of IL-2 and IFN-?in p35 group were significantly lower than those of control group and HK group,otherwise were the concentration of IL-4 and IL-10. Conclusion Pretreatment of dondor dendritic ceils with Ad-IL-12p35siRNA could prolonged cardiac allograft survival in recipicents.

AlM: To explore the different ages of congenital nasolacrimal duct obstruction in infants, take different treatment methods at different times.
METHODS:The 87 cases of 102 children were divided into three different age groups: the first group of 25d-3mo of age 21 cases 26 eyes; The second group >3mo-7mo 31 cases 36 eyes;The third group >7-24mo of age 35 cases 40 eyes. For the first group of infants, the implementation of the lacrimal sac nasolacrimal duct massage + eye drops; for the second group of infants, carry lacrimal pressure washing treatment; for the third group of infants, the implementation of the nasolacrimal duct probing treatment.
RESULTS: The first group of children through the nasolacrimal duct sac massage + drops tobramycin eye drops treatment unobstructed 12, the cure rate was 46. 2%;The second group of children through pressurized irrigation treatment lacrimal patency by 33, the cure rate was 91. 7%; The third group of children through the nasolacrimal duct probing unobstructed 36 treatment, the cure rate was 90. 0%. The second and third group were better than the first group (χ2=15. 71, P<0. 01;χ2=15. 27, P<0. 01);the treatment effect of the second and third groups was no significant difference (χ2=0. 02, P>0. 05).
CONCLUSlON:lnfants with congenital nasolacrimal duct obstruction should distinguish between ages, taking different treatments, in order to obtain a better therapeutic effect, and lacrimal pressure washing is the preferred way of treating infants with congenital nasolacrimal duct obstruction.

Objective To explore the application value of multiphase dynamic contrast-enhanced MRI (MDCE-MRI) in the early chemoradiation efficacy in cervical cancer.Methods Twenty-one patients with cervical cancer received chemoradiation.Routine MR scan and MDCE-MRI scan were examined at different stages, including pre-treatment, 15 days,1 month and 2 months after treatment.According to volume change of the tumor after treatment, the cases were mainly divided into complete remission(CR), partial remission (PR).The correlation between volume change of cancer after treatment and the time-signal intensity curve (TIC),mean time to enhancement(MTE),time to peak(TTP),maximum slope of increase(MSI),maximum slope of decrease(MSD), negative enhancement integral (NEI) were analysed.Results After system chemoradiation for 2 months,4 of enrolled patients got complete remission and 17 partial remission.The reduction rate of the tumor diameter was negatively correlated to MSI values(r=-0.877,P<0.05) and positively related with NEI (r=0.819,P<0.05) before the treatment.15 days after the treatment, the diminished rate of the tumor diameter had active relation with change of TTP(r=0.765,P<0.05) and NEI(r=0.775,P<0.05).It indicated that MSI and NEI values before cervical cancer chemoradiation and the variation of TTP and NEI after treatment for 15 days could help predict the variation tendency of cancer diameter.Chemoradiation and therapy 1 month later,for all the parameters'' AUC values,the change rate of NEI were the largest one.When the critical value was not less than 96.46%, the sensitivity was 82.4%, specificity was 75%.TIC curve of type Ⅰ increased, type Ⅲ decreased to disappear gradually.Conclusion MDCE-MRI can be used to predict the efficacy of chemoradiation in cervical cancer patients, of which the MSI, TTP and NEI are more sensitive.

Objective To investigate the effect of insulin and gliclazide therapy on endoplasmic reticulum (ER) stress and insulin sensitivity in the liver of type 2 diabetic rats.Methods A high fat diet plus a low-dose of streptozotocin was implemented to create a type 2 diabetic rats which were randomly divided into diabetes mellitus (DM) group,insulin treatment (INS) group and gliclazide treatment (GT)group; and healthy rats were as normal control group.Diabetic rats in INS and GT groups were given neutral protamine hagedorn (NPH) insulin and gliclazide respectively for 3 weeks.Protein expression levels of immunoglobulin binding protein (Bip),spliced X-box binding protein 1 (XBP-ls),phosphorylated c-Jun on serine 73 (p-c-Jun),phosphorylated insulin receptor substrate 1 on serine 307 (p-IRS-1),and glucose-6-phosphatase (G6Pase) in liver homogenate were detected by Western blotting.Results Compared with the normal rats,Bip and XBP-Is in the DM group were up-regulated (0.28 ±0.07 vs 0.90 ±0.10 for Bip;0.41 ± 0.07 vs 0.95 ±0.07 for XBP-1 s; both P ＜ 0.01 ) ; p-c-Jun (0.59 ± 0.18 vs 1.94 ± 0.03 ),p-IRS-1( 1.73 ± 0.18 vs 5.32 ± 0.22) and G6Pase (0.11 ± 0.01 vs 0.45 ± 0.01 ) were increased ( all P values ＜0.01 ).In the INS group,all of aforementioned changes were reversed (0.90 ± 0.10 vs 0.25 ± 0.04 for Bip; 0.95 ±0.07 vs 0.47 ±0.01 for XBP-1s; 1.94 ± 0.03 vs 0.50 ±0.10 for p-c-Jun; 5.32 ± 0.22 vs 1.59 ±0.32 for p-IRS-1 ; 0.45 ±0.01 vs 0.15 ±0.02 for G6Pase,all P values ＜0.01 ).In the GT group,all of aforementioned changes were also attenuated ( 0.90 ± 0.10 vs 0.53 ± 00.02 for Bip ; 0.95 ± 0.07 vs 0.78±0.02 for XBP-1s; 1.94 ±0.03 vs 1.33 ±0.11 for p-c-Jun; 5.32 ±0.22 vs 3.13 ±0.02 for p-IRS-1; 0.45 ± 0.01 vs 0.25 ± 0.01 for G6Pase,all P values ＜ 0.05).Furthermore,all of aforementioned protein levels were down-regulated more obviously in the INS group comparing to the GT group ( all P values ＜ 0.01 ).Conclusions Both insulin and gliclazide therapy could relieve ER stress and e-Jun N-terminal kinase activity and improved insulin sensitivity.The effect of insulin on Bip,XBP-1s,p-c-Jun,p-IRS-1 and G6Pase protein expressions is more obvious than that of glilcazide,which indicates besides lowering glucose,insulin might have protective effects of anti-inflammation,anti-oxidative stress or stimulation of lipid redistribution.

Objective To investigate the effective connectivity of limbic circuit in patients with major depressive disorder when they recognized dynamic positive face expressions,aiming to discuss the possible mechanism of emotion processing in depressed patients.Methods Eighteen depressive patients and eighteen well-matched healthy control volunteers participated in the experiment.All subjects were asked to recognize the emotion face during the magnetoencephalograph (MEG) scanning.The regions of interested (ROI) brain areas included the orbital frontal cortex (OFC),the anterior cingulated cortex (ACC),the amygdala (AMYG),the hippocampus and the insula.The MEG data were preprocessed by the SPM8 software and further analyzed by the Granger casual model (GCM).The non-parameter permutation was used to compare the value of effective connectivity between the healthy controls and the depressed patients.Results Compared with healthy controls,the effective connectivity from the ACC to the AMYG (P=0.0052),from the OFC to the AMYG(P=0.0046),from the Hippocampus to the ACC (P=0.0016),and from the ACC to the Hippocampus (P=0.0042)was significantly reduced in depressed patients.Conclusion The depressed patients display decreased interaction of the limbic circuit during the happy facial emotion processing,indicating that the depressed patients are unable to deal with the positive stimuli,and to certain extent,explaining the abnormal neuropathophysiological mechanism of positive stimuli in MDD.

OBJECTIVETo study operative effects for the treatment of multiple ligament injuries of knee joints.

METHODSFrom 2008 to 2013, 26 patients (17 males and 9 females) with multiple ligament injuries of knee joints were treated surgically. The average age was 40.7 years old, ranging from 29 to 55 years old. All the patients were treated with arthroscopic reconstruction of cruiate ligament with autogenous or allogeneic hamstrings and tendon, and at the same time received repair of medial collateral ligament and lateral collateral ligament, as well as the treatment of exterior and interior complex injuries. Nine patients received second stage operation after the initial operation for mistake or missed diagnosis, and other patients were treated at the first stage. The Lysholm scoring system was used to evaluate function and stability of knee joints before and after operation.

RESULTSAll the patients were followed up for an average duration of 1.6 years (ranged, 0.8 to 3.2 years). The mean awaiting time for operation was 1.2 months. The Lysholm score was improved from preoperative 42.5 +/- 4.5 (ranged, 33 to 48) to the latest follow-up 78.1 +/- 3.9 (ranged, 57 to 95). The function of knee joint was improved obviously in the arthroscopic reconstruction patients, with joint range of motion exceeding 900 and with Varus & Valgus tests near to normal. All the patients had negative findings in the Lachman test at 70 degrees of flexion.

CONCLUSIONArthroscopic reconstruction should be the first choice in treating multiple ligament injuries of knee joints. If the anterior and posterior cruciate ligament injuries can't be treated simultaneously, the posterior cruciate ligament injuries should be treated preferentially at the first stage and the anterior cruciate ligament injuries should be treated at the second stage. The diagnosis of posterior cruciate ligament is easy to be missed.

A high-performance liquid chromatography method of pre-column derivatization with 1-phenyl-3-methyl-5 -pyrazolone (PMP) has been established for determination of 6 kinds of monosaccharides simultaneously. A special Agilent HC-C18 column (4. 6 mm x 250 mm, 5 microm), optimized for the separation of PMP derivatives, was used at ambient temperature of 40 degrees C. The PMP derivatives elution was performed with a mixture of 0.1 mol x L(-1) phosphate buffer (pH 6. 8) and acetonitrile in a ratio of 84: 16 at a flow rate of 1 mL x min(-1), and UV absorbance of the effluent was monitored at 245 nm. The results showed that the polysaccharides from exopleura of Ginkgo biloba were acidic heteropolysaccharides mainly containing mannose, rhamnose, D-galacturonic acid, glucose, galactose, arabinose, with the molar ratio of 0.032: 0.14: 0.296: 0.403:0.106: 0.046.

Purpose: This study sought to understand Taiwanese women’s decisional experiences regarding prenatal screening procedures and diagnostics. Methods: A hermeneutic phenomenological design guided semistructured interviews with 33 women who were 36 weeks pregnant. Data were collected between February and October 2016. Verbatim transcripts were analyzed following hermeneutic circle to cocreate an understanding of Taiwanese women’s decision-making in prenatal screening and diagnostics. Results: Women’s existential experiences were derived from their decision-making process on prenatal screening procedures and diagnostics for chromosomal aneuploidy. These decisional experiences were captured by four theme clusters and eight themes, which were inductively derived from 16 meaning units: (1) accessing health information; (2) considering what was best for my baby; (3) considering family finance; and (4) feeling anxiety posttest. Conclusion Participants made informed choices on several prenatal screening procedures, ostensibly, based on their personal values and considerations. During the decision-making process, often-cited benefits of genetic screenings were emphasized, but test limitations were often unheeded. A fundamental need for supportive information in decision making was further identified with recommended strategies. Hence, a revision of traditional genetic counseling approaches is recommended. As genomics technologies are increasingly available during antenatal services, women should be sufficiently educated about them to support decision making.
