Objective To discuss the influence on peripheral circulation and oxygenation of different colloid osmotic pressure (COP) in pediatric cardiac surgery under cardiopulmonary bypass (CPB).Methods Sixty cases of non-cyanotic congenital heart disease patients under 10 kg were randomly selected and divided into 3 groups(n =20) according to the different COP level.COP values was adjusted by the ultrafiltration technique and colloid addition.The perioperative(T1-T6) arterial lactate level,different value between skin and rectal temperature,peripheral oxygen saturation (SpO2) and oxygenation index (OI) were observed in order to determine the different effect on peripheral circulation and oxygenation.Meanwhile,mechanical ventilation time and ICU time were recorded.Results The variation tendency of arterial lactate level was similar in each group,the value in the COP ＞ 18 mmHg (1 mmHg =0.133 kPa) group(group C) was significantly higher than COP 10-15 mmHg group (group A) and COP 16-18 mmHg group (group B) in T3 and T4,after CPB weaned,the values of Group A (1.25 ± 0.42) and Group C (1.33 ± 0.51) were higher than Group B (0.71 ± 0.29) at T6 point (P ＜ 0.05);the variation tendency of SpO2 was similar in each group too,the value of group C was significantly lower than group A and B at T5 point,the values of group A and C were significantly lower than group B at T6 point,P ＜ 0.05;the different value between skin and rectal temperature in group A was significantly higher than group B and C from T1 to T2 point(P ＜0.05),but not in T3 to T6 point;The minimal OI values of all the groups were appeared in T4 point,group B value was significantly higher than A and C in all time point,group C value was the lowest(P ＜0.05);the mechanical ventilation time in group B(2.13 ± 1.36) days and group C (2.93 ± 1.69) days were significantly lower than group A (3.83 ± 1.47) days,P ＜ 0.05.ICU time of group B (3.9 ± 1.1) days was significantly lower than group A (5.7 ± 2.5) days and C (6.0 ± 1.5) days.Conclusion During the pediatric CPB,the improper COP level will lead to bad oxygenation and poor peripheral circulation,got different prognosis ultimately.A reasonable COP level(16-18 mmHg) will do benefits to all the pediatric patients.

ABSTRACT The taboos of man-spirit (RenShen) and bottom-spirit (KaoShen) are two kinds of time-related contraindications that are more commonly seen in the literature of acupuncture and moxibustion. The meaning of man-spirit is often extended to qi-blood or mind, or else directly equals to heaven-spirit (TianShen). It is highly possible that the bottom-spirit is subordinate to man-spirit, and both Taoist philosophy and the SanCai theory declare the importance of bottom in human body. The violation of contraindications could lead to diseases in the neighborhood where man-spirit travels. However, the results are generally recorded as ulcer, lingering disease and death in most medical texts. From Ming dynasty, more and more doctors have expressed disapproval of man-spirit and bottom-spirit.

Objective To investigate the characteristics of hepatitis C viurs (HCV)infection and its genotypes in Yancheng area . Methods A total of 20 185 cases of subjects receiving healthy examination were collected ,and fasting blood levels of serum anti‐HCV were detected .Clinical data of patients with HCV infection were statistically analysed .HCV genotypes and levels of HCV RNA were detected ,and their clinical prognosis was judged by type‐B ultrasonic .Results The total infection rate of HCV was 1 .22% .The infection rate of male was higher than that of female and the infection rate was increased with the elevation of age .The genotype 1b was accounted for 73 .17% .The results of type‐B ultrasonic shown that all patients infected with genotype 6 and 1b/2a HCV only had liver damage .80 .77% of patients infected with genotype 2a HCV had liver damage ,which was higher than that of patients infected with 16 and 3a+3b genotypes .Conclusion Most of HCV infected patients are male ,and the infection rate might be increased with the elevation of age .The prognosis is in various different genotypes of HCV ,which indicates that the prognosis could be evaluated by genotyping .

This study is to explore the amelioration of piperine on chronic acute combining stress rat with depression-like behavior, visceral sensitivity, and its effect on the expression of serotonin (5-HT) and synaptophysin. Forty two SD rats were divided into seven groups: blank group, model group, piperine (12.5, 25, 50 and 100 mgkg-1, ig) and imipramine (10 mgkg-1, ip) groups. The rat model of irritable bowel syndrome was established by chronic acute combining stress, and then to evaluate depression-like behavior and visceral sensitivity. The expressions of 5-HT and synaptophysin in the hippocampus and colon were determined by high performance liquid chromatography (HPLC) and Western blotting, respectively. The duration of immobility of IBS rat in the forced swimming test had been significantly increased, the sucrose consumption of IBS rat had been reduced and visceral sensitivity was obviously elevated in the IBS model group as compared with those in the normal control group (P<0.05, P<0.01). As compared with those in the normal control group, the expression of 5-HT significantly decreased, 5-HIAA/5-HT ratio significantly increased in the hippocampus of IBS model group (P<0.05), but opposite presentations were noted in the colon (P<0.05). As compared with that in the normal control group, the synaptophysin expression in the hippocampus decreased significantly but obviously increased in the colon (P<0.05). Piperine improved the behavior of IBS rats, and reversed the levels of 5-HT and 5-HIAA, and 5-HIAA/5-HT proportion in the hippocampus and colon (P<0.05); besides, they significantly reverse the synaptophysin level in the hippocampus and colon (P<0.05). The presence of depression and visceral sensitivity had been changed in IBS rats, with abnormal expression of 5-HT and synaptophysin in the brain-gut system. Piperine can ameliorate the changes of the behavior and regulation of serotonin and synaptophysin expression in IBS rat model.

Objective To study the gene expression profiles of megakaryocytes(MKs) from human cord blood CD34+ cells in vitro expanded and to understand megakaryopoiesis at the molecular level. Methods CD34+ cells were isolated using density gradient centrifugation and magnetic activated cell sorting. The cells were cultured and stimulated with recombinant human TPO ( 100 ng/ml). After 12 days, the MKs fraction was separated using an anti-CD41 monoclonal antibody by immunomagnetic sorting. The gene expression profiles of MKs, non-MKs as well as meg-01 cells were studied by gene chip assay. THBSI, HOX A9,β-actin, lL-8,Annexin A6, FGF-8 were selected to validate the gene chip results by RT-PCR. Results A total of 116 genes between MKs and non-MKs cells were significantly different, 52 genes were up-regulated and 64 genes were down-regulated. In addition, 158 genes between MKs and meg-01 cells were significantly different, 71 genes were up-regulated and 87 genes were down-regulated. THBSI showed higher expression in MKs than in non-MKs. HOXA9 showed lower expression in MKs than in non-MKs. The expression of β-actin did not show any significant difference in MKs and non-MKs. IL-8 showed higher expression in MKs than in meg-01 cells, while ANXA6 showed lower expression in MKs than in meg-01 cells. The expression of FGF-8 did not show any significant difference between MKs and meg-01 cells. Conclusions MKs, non-MKs and meg-01 cells show different gene expression profiles. The regulatory genes include stress response genes,immune related genes, DNA synthesis and repair genes, metabolism genes, pro-onco genes and tumor suppressor genes.

A 29-year-old woman was admitted to the Department of Rheumatology,Peking Union Medical College Hospital due to intermittent rashes,fever and headache.Palpable purpura were symmetrically distributed on the extremities and trunk.Other manifestations included headache with nausea and vomiting.Elevated white blood cell (WBC) count,platelet (PLT) count,erythrocyte sedimentation rate (ESR) and C-reactive protein were the main laboratory findings.Antinuclear antibodies and antineutrophil cytoplasmic antibodies were negative.Examination of the cerebrospinal fluid (CSF) revealed high intracranial pressure,while routine cytology and biochemical tests of CSF were normal.Head MRI scan and PET-CT did not detect remarkable findings.A diagnosis of systemic vasculitis was confirmed by the biopsy of skin lesion which showed inflammatory infiltration of the muscular vessel wall.Combination therapy of corticosteroids and cyclophosphamide lead to a rapid improvement in clinical symptoms and laboratory parameters.The patient was in stable remission till 6 month follow-up.
