Objective To investigate the changes and correlative factors of natural killer(NK)cells and T lymphocyte subpopulations levels in neonates with hypoxic-ischemic encephalopathy(HIE).Methods Peripheral blood samples were collected from 50 neonates with HIE.The percentages of NK cell(CD3~-CD_(16)~+CD_(56)~+) and T lymphocyte subpopulations including CD3~+,CD4~+,CD8~+ and CD4~+/CD8~+ ratio were determined by Flow Cytometr(FCM).Meanwhile,20 healthy neonates were served as controls.Results (Le)-vels of NK cell,CD3~+,CD4~+,CD8~+ and CD4~+/CD8~+ ratio in neonates with HIE were significantly lower than those in control group(all P0.05).Spearman correlation analysis showed that there were negative correlation between the NK cell,CD3~+,CD4~+,CD4~+/CD8~+ ratio and stages of HIE(all P0.05). Linearregression analysis showed that there was a positive correlation between NK cell and gestationalages((P

According to the phenomenon that the curriculum of psychological health education for college students is theoretical,lack of experience and the teaching form is single,this research attempts to private a blended teaching which is based on the small private online course (SPOC) and experiential teaching.The content of mental health is divided into theoretical knowledge and experience knowledge.And the theoretical knowledge is taught through online teaching in the form of massive open online courses (MOOC),while the experiential knowledge is taught by pure experiential teaching in the classroom.The study has summed up 3 stages of learning mode:learning before class,teaching experience and reflection after class.This changes the single classroom theory teaching to students experience learning.Besides,formative evaluation is used as assessment methods,which has enhanced the effectiveness of the course and at the same time,it has also promoted the improvement of teachers' teaching level effectively.

Objective To examine how stroke affects muscle coordination and whether muscle function will be improved after rehabilitation.Methods Ten stroke patients with mild hemiparesis and six age-and sex-matched controls were investigated at baseline.Velocity-encoded phase-contrast magnetic resonance imaging (VE-PC MRI) and surface eleetromyography (sEMG) were performed to evaluate muscle coordination of thigh muscles during knee extension and flexion and the effect of rehabilitation. Results Using VE-PC MRI,we found that the peak velocity of rectus femoris was lower in the affected limb (P

OBJECTIVETo investigate the changes and the clinical significance of N-terminal pro-brain natriuretic peptide (NT-proBNP) and glycogen phosphorylase isoenzyme BB (GPBB) levels in neonates with asphyxia complicated by myocardial injury.

METHODSSixty-four neonates with asphyxia (39 mild, 25 severe) were enrolled. Of the 64 neonates, 30 had myocardial injury and 34 did not develop myocardial injury. Twenty-five healthy neonates served as a control group. Plasma levels of NT-proBNP and GPBB were measured using ELISA. Myocardial enzymes and cardiac troponin I were stimultaneously measured, and electrocardiography and chest radiographs were obtained.

RESULTSThe plasma levels of NT-proBNP and GPBB in neonates with myocardial injury were significantly higher than those in neonates without myocardial injury and in the control group (P<0.01). The neonates with severe asphyxia had significantly increased plasma NT-proBNP and GPBB concentrations compared to those with mild asphyxia and the control group (P<0.01). Spearman rank correlation analysis showed that plasma NT-proBNP level was positively correlated with plasma GPBB level in neonates with asphyxia. Plasma levels of NT-proBNP and GPBB were also positively correlated with plasma levels of CK-MB, CK and LDH (P<0.01).

CONCLUSIONSBoth NT-proBNP and GPBB can be used as biomarkers of myocardial injury in neonates with asphyxia. The measurement of plasma NT-proBNP and GPBB levels was useful in early identification of myocardial injury and severity evaluation in neonates with asphyxia.

Objective To explore the application value and evaluate the safety of ESD in treatment of early colorectal cancer. Methods The clinical data of patients with early colorectal cancer admitted from May 2014 to May 2016 were retrospectively analyzed. According to the different operation methods, the patients were divided into EMR group and ESD group. The changes of clinical efficacy, safety and inflammatory index level were compared between the two groups. Results 126 patients were involved in the study. The operative time was longer than that of the lesion diameter < 2 cm (P < 0.05) when the lesion diameter was more than 2 cm. The operative time of ESD group was longer than that of EMR group. The resection rate and complete resection rate of lesion were higher than that of EMR group (P < 0.05). When the diameter of lesion was ≥ 2 cm, the operation time of ESD group was longer than that of EMR group. In EMR group, the whole and complete resection rate were lower than that in the diameter less than 2 cm (P < 0.05). There was no significant difference in the levels of TNF- α IL-6 and CD3+and CD4+between the two groups before operation (P > 0.05), but one week after operation, the levels of CRP, TNF- α and IL-6 was lower than that of EMR group (P < 0.05), while the levels of CD3+and CD4+were higher (P < 0.05). There was no significant difference in the incidence and recurrence rate of anastomotic leakage (P > 0.05). The incidence of hemorrhage in ESD group was higher than that in EMR group (P < 0.05). Conclusion ESD was effective in treatment of early colorectal cancer. The stress response was small and the recurrence rate was low, but the bleeding rate was higher than that in EMR group, so the monitoring should be strengthened.

This study was aimed to investigate the influence of timing using G-CSF after chemotherapy on graft yield of mobilized peripheral blood stem cells for autoPBSCT. 39 patients with lymphoma or multiple myeloma (MM) received the same chemotherapy mobilization regimen, including CTX 400 mg/m² d1; VLB 2 mg/m(2) d1; Ara-C 60 mg/m ²× d1-5; VP-16 60 mg/m² × d1-5; and prednisone 40 mg/m² × d1-5. The historical control group (12 cases) received G-CSF subcutaneously (filgrastim) at the first restoration after the initial nadir of the peripheral WBC count. The experimental group (27 cases) received G-CSF during the steady rise of the WBC count (end of fluctuating after initial nadir). G-CSF was given in a single daily subcutaneous dose of 5 µg/kg until the final PBSC apheresis. When the peripheral WBC and mononuclear cell (MNC) counts reached 10 × 10⁹/L and 1.0 × 10⁹/L respectively, leukapheresis was carried out using the COBE Spectra blood cell separator. The results indicated that despite there was comparable treatment with alkylating agents between 2 groups, a significantly increased yield of CD34 positive cells was observed in the experimental group (26.4 × 10⁶/kg), as compared to the historical control group (3.1 × 10⁶/kg) (p = 0.0031). It is concluded that the appropriate timing for the use G-CSF mobilization after chemotherapy is important to increase the CD34(+) cell yield in auto-graft.

OBJECTIVETo evaluate the efficacy and safety of a China made adefovir dipivoxil (ADV) treatment for hepatitis B e antigen-positive patients with chronic hepatitis B.

METHODSTwo hundred and thirty patients with chronic hepatitis B who were positive for hepatitis B e antigen (HBeAg) were randomly put into groups A or B, and 58 patients with lamivudine-resistant chronic hepatitis B were randomly put into groups C or D. During the first 12 weeks of the trial, 112 patients in group A and 115 patients in group B received 10 mg of ADV and a placebo once a day; 28 patients in group C received 100 mg of lamivudine (LMV) and 10 mg of ADV; 29 patients in group D received 100 mg of LMV and a placebo once a day. In the second trial period, all patients received ADV for 36 weeks. The primary checking criterion was the serum HBV DNA change during the treatment. The secondary ones were alanine aminotransferase (ALT) normalization, HBeAg loss, and HBeAg seroconversion.

RESULTSAt week 12, the median serum hepatitis B virus (HBV) DNA level of group A (ADV-ADV) was reduced 2.8 log10 copies/ml, significantly greater than that of group B (placebo-ADV) of 0.3 log10 copies/ml reduction (P = 0.000). At week 48, the median serum HBV DNA level of group A and group B were reduced 3.6 and 3.4 log10 copies/ml respectively. At week 12, the median serum HBV DNA level of group C (LMV+ADV) was reduced 3.0 log10 copies/ml, significantly greater than that of the group D (LMV+placebo) of 0.16 log10 copies/ml reduction (P = 0.000). At week 48, the median serum HBV DNA level of group C and group D were reduced 3.6 and 3.8 log10 copies/ml respectively. Only 5.56% (16/288) patients had adverse events that were mild to moderate. There was no significant difference in the change of serum creatinine compared with their baseline levels.

CONCLUSIONIn our HBeAg positive lamivudine-resistant chronic hepatitis B patients, 48 weeks of ADV treatment was safe and resulted in significant virological and biochemical improvements.

OBJECTIVETo investigate the correlation between blood flow assessed by CT perfusion imaging and characteristics of microvascular ultrastructure in non-small cell lung cancer (NSCLC).

METHODStwenty-eight patients with non-small cell lung cancer proven surgically and pathologically underwent perfusion CT examination. The patients were divided into a hyper-perfusion group and a hypo-perfusion group by the median value of blood flow, and then the differences of microvascular ultrastructure in the two groups were analyzed.

RESULTSThe median BF value of the 28 patients was 36.40 ml×100 g(-1)×min(-1). Take this median value as the boundary, the group with hypo-perfusion showed a significantly lower BF value than the group with hyper-perfusion [(30.84 ± 4.79) ml×100 g(-1)×min(-1) vs. (49.67 ± 10.89) ml×100 g(-1)×min(-1), t = -5.925, P < 0.001]. The group with lymph node metastasis showed a significantly lower BF value than the group without lymph node metastasis [(30.78 ± 5.24) ml×100 g(-1)×min(-1) vs. (50.73 ± 11.16) ml×100 g(-1)×min(-1), t = 3.490, P = 0.015]. The maturity of microvessels of the hyper-perfusion group was higher than that of the hypo-perfusion group. Under the electron microscope, the microvessels in the hypo-perfusion group showed a more narrow lumen, poorer integrity of basement membrane, a more close relationship between cancer cells and microvascular wall, and cancer cells were more easily seen in the microvascular lumen.

CONCLUSIONThe blood flow value of CT perfusion imaging may be related with the abnormal microvascular ultrastructure, and may be helpful to the prediction of metastasis risk in NSCLC.
