Openfield test was performed to detect the behavior of rats. Immunohistochemistry was used to observe the changes of BDNF level.Results:Compared to the control group,the number of depressed animals was much less than that of normal animals.Conclusion:The level of BDNF decrease significantly in experimental depressive model of rats.

Objective To observe the effects of live combined bifidobacterium,lactobacillus and enterococcus powder on immunoglobulin E (IgE) and interleukin-17 (IL-17) in atopic children with bronchiolitis.Methods Sixty cases of atopic children with bronchiolitis were randomly divided into the therapy group (30 cases) and the control group (30 cases).Twenty-five healthy children were enrolled as the healthy control group.Both the therapy group and the control group were given traditional therapy.The therapy group received live combined bifidobacterium,lactobacillus and enterococcus powder for 2 months.The change of IgE and IL-17 levels were observed during the acutestage,remission stage and after receiving live combined bifidobacterium,lactobacillus and enterococcus powder for 2months.Results (1) The levels of IgE and IL-17 of therapy group[(132.36 ±9.50) μg/L and (77.76 ±7.95)μg/L] during acute stage were markedly higher than those in the healthy control group [(52.80 ±4.92) μg/L and (46.92 ±4.79) μg/L] (all P ＜0.001).The levels of IgE and IL-17 of control group [(128.83 ± 8.06) μg/L and (76.61 ±6.18) μg/L] during remission stage were markedly higher than those in the healthy control group [(52.80 ±4.92) μg/L and (46.92 ± 4.79) μg/L] (all P ＜ 0.001).(2) The levels of IgE of therapy group (56.67 ± 9.20)μg/L after receiving live combined bifidobacterium,lactobacillus and enterococcus powder for 2 months were markedly lower than those in the control group (70.50 ± 11.38) μg/L (P ＜ 0.001).The levels of IL-17 of therapy group [(49.63 ± 6.35) μg/L] at the time after receiving live combined bifidobacterium,lactobacillus and enterococcus powder for 2 months were markedly lower than these in the control group (54.77 ± 6.33) μg/L (P =0.003).Conclusion Receiving live combined bifidobacterium,lactobacillus and enterococcus powder for two months can decrease the IgE and IL-17 levels in atopic children with bronchiolitis.

Objective To evaluate the efficacy and drug-related toxicities of pemetrexed disodium in the treatment of advanced pulmonary adenocarcinoma.Methods A total of 41 patients who had received pemetrexed disodium and cisplatin therapy were retrospectively reviewed.The patients were given respectively pemetrexed disodium (500 mg/m2,1st day) and cisplatin (200 mg/m2,1-4 day) until disease progressed.The clinical outcomes and adverse reactions were observed.Results The CR rate was 7.3 ％ (3/41),PR rate was 22.0 ％ (9/41),SD rate was 31.7 ％ (13/41),PD rate was 39.0 ％ (16/41),the DRR was 29.3 ％ (12/41),DCR rate was 61.0 ％ (25/41),the median PFS was 5 months.The age,sex,smoking history,staging and timing of treatment had not the statistics difference on ORR and DCR.The sex,smoking history,staging and timing of treatment had not the statistical difference on PFS (P ＞ 0.05).The main toxicities were fatigue,nausea,vomiting and myelosuppression.Conclusion The pemetrexed disodium and cisplatin are feasible and welltolerated for advanced pulmonary adenocarcinoma patients.

Objective To investigate the safety of cleaning and disinfection of duodenoscope used in endoscopic retrograde cholangiopancreatography (ERCP).Methods The duodenoscopes,which were used in Endoscopy Center of Digestive Disease Hospital,Heilongjiang Provincial Hospital from May 4 to May 31 2016,were cleaned manually and disinfected with sterilization powder.The samples from elevator and elevator channel were collected for bacterial culture to evaluate the safety of clinical application of duodenoscope.Results Among 60 high level disinfections,one was excluded because disinfectant concentration wasn't effective.Among 59 elevator samples no positive cultures were detected,while among 59 channel samples,4(6.8％) cultures were positive and all from the same duodenoscope,including 3 cases of Klebsiella pneumonia and 1 case of Pseudomonas aeruginosa.Conclusion Sterilization powder is effective for disinfection of duodenoscope used for ERCP.Residual organic material can't be excluded from elevator sample even if it is negative for culture.Duodenoscope with high level disinfection still has the risk of transmitted infection,and should be monitored regularly by culture and reprocessed in time.

Objective To observe any effect of low intensity pulsed ultrasound (LIPUS) on the expression of integrin-focal adhesion kinase (FAK)-mitogen-activated protein kinase (MAPK) mechanochemical transduction pathway-related proteins in the chondrocytes of rabbits with knee osteoarthritis (OA).Methods Of the 18 New Zealand white rabbits selected for the study,twelve received knee anterior cruciate ligament transection to model OA.The remaining 6 rabbits served as normal controls.At the 4th week after modeling the rabbits were sacrificed and chondrocytes were isolated and cultured in vitro.All the cultured cells were randomly divided into three groups:a normal control group (NC),an OA model group (OA) and an OA model plus LIPUS group (OA + LIPUS).When the cells had been cultured to the 2nd passage,the NC group and OA group cells had received no treatment.The OA + LIPUS group cells were exposed to 40 mW/cm2 of LIPUS for 20 min,once a day for 6 days.The expression of collagen protein type Ⅱ,aggrecan,MMP-13,integrin β1 p-FAK and p-p38,p-ERK1/2 and p-JNK Mapks were detected by Western blotting.Results Compared with the NC group,the expression of collagen type Ⅱ and aggrecan was significantly lower in the OA and OA + LIPUS groups,with more significantly lower expression of collagen type Ⅱ and aggrecan in the OA group than in the OA + LIPUS group.Compared with the NC group,the expression of MMP-13 was significantly higher in the OA and OA + LIPUS groups,with a significantly larger increase in the OA group.Compared with the NC group,the expression of integrin β1 and p-FAK was also significantly higher in the OA and OA + LIPUS groups,with a significantly larger increase in the OA + LIPUS group.Compared with the NC group,the expression of p-p38,p-ERK1/2 and p-JNK was also significantly higher in the OA group,but compared with the OA group,the expression of those kinases was,on average,significantly lower in the OA + LIPUS group.Conclusions LIPUS can inhibit the degradation of collagen type Ⅱ and aggrecan,and inhibit the expression of MMP-13,p-p38,p-ERK1/2 and p-JNK in OA chondrocytes,at least in vitro.At the same time,LIPUS can increase the expression of integrin β1 and p-FAK.The results show that LIPUS may activate an integrin-FAK-MAPK mechanochemical transduction pathway to induce changes in the extracellular matrix of chondrocytes.

Objective To investigate the effect of multidisciplinary diagnosis and treatment including ex-utero intrapartum treatment (EXIT) procedure to improve the prenatal survival rate of fetus with neck mass.Methods Multidisciplinary diagnosis and treatment model were carried out in four pregnancy women with fetal neck mass from September 2007 to February 2010.The model included prenatal assessment and monitoring,EXIT procedure during cesarean section,neonatal reassessment and surgical treatment by the cooperation of obstetricians,neonatologists,children surgeons,sonographers and anesthetists.Results All patients underwent cesarean section after 37gestational weeks.Mean delivery time was 37+4 weeks (37-38+3 weeks); mean birth weight was 2972 g (2600-3250 g); mean operation time was 4 min (2-7 min).The gestational age of primary diagnosis of fetal neck mass was 24-34 gestational weeks.After delivery,the size of neck mass was from 3.0 cm × 2.0 cm × 1.0 cm to 6.2 cm× 5.8 cm × 6.8 cm.The tracheal compression and displacement were found by color doppler ultrasound scan and magnetic resonance imaging in all cases.Two of them were completed with polyhydramnios and the others with normal volume of amniotic fluid.EXIT procedure was successfully carried out during cesarean section.Neonatal reassessment showed the trachea of three infants were obviously compressed and lapsed by enhanced CT; the infants relied on mechanical ventilation after birth and underwent operation on day 6 to 8.Tracheal impression was not presented in one infant and trachea cannula was removed on the second day,operation was not performed.All of those infants had good outcomes.Conclusions The multidisciplinary diagnosis and treatment model,including EXIT procedure,is a safe,efficient and feasible strategy,which is necessary for fetus with neck mass.

OBJECTIVETo evaluate the therapeutic effect of interferon therapy after transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma associated with hepatitis B virus.

METHODSSixty-two patients with advanced primary hepatocellular carcinoma associated with hepatitis B virus was randomly divided into 2 groups. Thirty-one cases were treated with TACE and Interferon. Thirty-one cases with TACE only. HBV DNA, clinical effect, intrahepatic tumor recurrence rate and survival rate were studied.

RESULTSOf the 31 patients in TACE+IFN group, 17 (54.8%) were negative for HBV DNA at the end of treatment. None of TACE group was negative for HBV DNA. The intrahepatic tumor recurrence rate at 1 year and 2 years in TACE+IFN group was 16.1%, 29.0%, compared with 38.7%, 61.3% in TACE group (chi-square = 3.97, chi-square 6.51, P < 0.05). The survival rate in the former was 83.9% and 74.2% respectively, compared with that of 61.3% and 38.7% in the latter (chi-square = 3.97, chi-square = 7.94, P < 0.05).

CONCLUSIONInterferon therapy after transcatheter arterial chemoembolization resulted low recurrence and long survival in patients with hepatocellular carcinoma associated with hepatitis B virus. This method showed fewer side effects and should be recommended.

Objective To explore the correlationships between microperfusion diffusion indexes derived from intravoxel incoherent motion(IVIM)and perfusion values measured by arterial spin labeling (ASL)in renal allograft. Methods A total of 76 renal allograft recipients and 26 age-matched volunteers (group 0)were included in this prospective study. All subjects were underwent conventional MRI, IVIM and ASL MRI which were performed in the oblique-sagittal plane. Seventy-six recipients were divided into two groups based on the estimated glomerular filtration rate(eGFR):recipients with good allograft function(group 1, eGFR≥ 60 ml · min-1 · 1.73m-2,n=44)and recipients with impaired allograft function(group 2, eGFR<60 ml · min-1 · 1.73m-2,n=32). Three IVIM indexes values, including true diffusion coefficient(ADCslow), pseudo-diffusion coef fi cient(ADCfast), perfusion fraction(PF), and one ASL index value of renal cortex(renal blood flow, RBF)were measured. One-way analysis of variance and the least significant difference were used to compare the different of each cortical index values among three groups. Correlations between the ADCslow, ADCfast, PF, RBF and eGFR as well as the correlation among the indexes were evaluated using Pearson correlation coefficients. Results For cortical ADCslow, ADCfast, PF and RBF values, allografts with good function and impaired function showed significantly differences compared healthy controls(all P<0.01). In allografts with good function, cortical ADCslow,ADCfast,PF showed no significantly differences compared with controls(all P>0.05), but RBF value was significantly lower(P<0.05). The ADCslow, ADCfast, PF and RBF values of renal cortex were significantly lower in allografts with impaired function compared to allografts with good function(all P<0.01). In renal allografts, there were significant positive correlations between cortical ADCslow, ADCfast, PF, RBF value and eGFR(r values were 0.604, 0.552, 0.579 and 0.673, all P<0.01). Cortical ADCfast and PF value exhibited a significant correlation with RBF for recipients(r values were 0.501 and 0.423, all P<0.01). Conclusion Cortical ADCfast and PF values derived from IVIM and RBF measured by ASL show a significant positive correlation in renal allografts.
