OBJECTIVETo observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia.

METHODSTotally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups.

RESULTSCompared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05).

CONCLUSIONTreatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

ObjectiveTo identify serum specific protein biomarkers for the early diagnosis of lymphoma patients by using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS)protein chip array.MethodsSELDI-TOF-MS technique and weak cation exchanger (WCX2)protein chip were used to detect the serum proteomic patterns of 96 patients with lymphoma (86 patients with non-Hodgkin lymphoma and 10 patients with Hodgkin lymphoma)and 30 normal control.The serum level of LDH were measured by biochemical methods,the serum level of β2-MG and CA125 were detected by enzyme-linked immunosorbent assay (ELISA).ResultsFour protein peaks pattern mass/charge ratio (M/Z) 6880,8564,8692 and 13751 were decreased in lymphoma patients,and they could be used to distinguish lymphoma from healthy people and other malignant tumors.Their sensitivity and specificity were 82.29 ％ and 80.00 ％,78.13 ％ and 73.30 ％,75.00 ％ and 80.00 ％,71.88 ％ and 83.30 ％ respectively in lymphoma patients.When it was used to early diagnosing lymphoma in stage Ⅰ or Ⅱ,the sensitivity of four protein peaks pattern (M/Z 6880,8564,8692 and 13 751) were 77.55 ％,71.43 ％,71.43 ％ and 67.35 ％respectively and the specificity of all four protein peaks pattern were 100.00 ％.Four protein peaks pattern sensitivity were higher than LDH,CA125 and β2-MG respectively.ConclusionApplication of SELDI-TOF-MS can be of great potential for the early diagnosis of lymphoma patients.

Methylacetoacetyl-CoA thiolase deficiency (T2 deficiency) is a rare congenital and metabolic disease affecting the ketone body and isoleucine metabolism. The typical symptoms are refractory metabolic acidosis, in which large amounts of 2-methyl-3-hydroxybutyry1 carnitine, 2-methyl-3-hydroxybutyrate and tiglylglycine are often detected in the blood and urine. We herein describe an atypical case of T2 deficiency with a high level of 3-hydroxybutyrate and a low level of 2-methyl-3-hydroxybutyrate in the urine. Such a case was diagnosed by urinary organic analysis in combination with gene mutation evaluation. Organic acids in the urine were measured using a gas chromatography mass spectrometer and all exons were sequenced via deep sequencing. Molecular biology analysis confirmed the presence of a homozygous mutation in the acetyl-CoA acetyltransferase 1 (ACAT1) gene. The patient received a special diet of deeply hydrolyzed protein milk powder and raw corn starch. She was followed about 6 months. There were no ketoacidotic episodes and hypoglycemia even when she had fever. In conclusion, patients with atypical features of T2 deficiency should also be investigated early. Gas chromatography mass spectrometry and next-generation full exome sequencing may be helpful in diagnosis.

OBJECTIVETo analyze the clinical effectiveness of Compound Danshen Injection (CDI) in treating patients with early onset severe preeclampsia.

METHODSOne hundred and twenty patients with early onset severe preeclampsia were recruited and their gestational age ranged between 26 and 34 weeks. Sixty patients who volunteered to receive CDI were recruited as the treatment group, while 60 inpatients were recruited as the control group at the same time period. The routine therapy was given to those in the control group. CDI was intravenously dripped to those in the treatment group additionally by adding in 250 mL 5% glucose injection, once daily. The treatment for all lasted for 7 successive days. The D-dimer (DD), fibrinogen (Fg), hematocrit (HCT), tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), mean arterial pressure (MAP), 24 h urine volume (UV), 24 h urine protein (24 hUP), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (apoA1), apolipoprotein B (apoB), umbilical arterial S/D ratio (S/D), and amniotic fluid index (AFI) were compared between the two groups before and after treatment. The placenta weight (PW), neonatal weight (NW), 1 min Apgar scoring were compared between the two groups before and after treatment.

RESULTSThere was no difference in DD, Fg, HCT, t-PA, PAI-1, MAP, UV, 24 hUP, TC, TG, HDL-C, LDL-C, apoA1, apoB, S/D, or AFI between the two groups before treatment (P>0.05). In the treatment group PAI-1, Fg, and 24 hUP decreased more after treatment, and they were lower than those of the control group after treatment. The UV and AFI increased and they were higher than those of the control group after treatment with statistical difference shown (P<0.05, P<0.01). In the control group the UV increased and 24 hUP decreased after treatment (P<0.01). There was no improvement in the rest indices (P>0.05). The PW, NW,and 1 min Apgar score > or = 7 were all higher in the treatment group than in the control group, showing statistical difference (P<0.05).

CONCLUSIONCDI was helpful to improve the high condensation state of patients with early onset severe preeclampsia, protect important organs of the mother, and improve the prognosis of neonates.

The purpose of this study was to observe the ultrastructure of human umbilical cord mesenchymal stem cells (hUCMSC). hUCMSC from full-term newborn umbilical cord were isolated and cultured by collagenase digestion, and then subcultured, amplification, and cell morphology was observed by microscopy. The immunophenotype and trilineage differentiation potential of hUCMSCs at passage 3 were analyzed. Transmission electron microscopy and scanning electron microscopy were used to observe the ultrastructure of hUCMSC. The results indicated that appearance of hUCMSC was spindle-shaped and polygonal, and nuclei were observed. hUCMSC expressed immunophenotype CD44, CD73, CD105, did not express CD34, CD45, CD31 and human leukocyte antigen HLA-DR. hUCMSC were capable of adipogenic, osteogenic, and cartilage differentiation; the short and thick microvilli processes were seen at the surface of hUCMSC by scanning electron microscope. Two different cell morphologies of hUCMSC were seen under transmission electron microscope, the one was a quiescent period in which a large and round or oval nucleus only one nucleolus were seen, cytoplasmic organelles were less; the other was in a relatively active period in which one or two nuclei in the same one cell were observed, the organelles were rich, structure was clear, expansion of the mitochondria was visible. It is concluded that the cells successfully isolated and cultured from umbilical cord, which possess biological characteristics of MSC and display two different states of ultrastructure.

The effects of the feed attractants on Whitmania pigra were studied. The average weight of Wh. pigra were 5.0 g. Arginine was selected as feed attractants, xanthan gum was selected as feed substrate. The times of Wh. pigra going into the inducing room were recorded. The water temperature was 22-25 degrees C during the whole experiment. Arginine that had better inducing effect was chosen to carry on in the gradient experiment. The results showed that the best inducing effect was found when the added amount of arginine was 0.3%, which was close to the arginine content of the natural body fluid of Wh. Pigra and Bellamya purificata, 2.97 mg x g(-1).

OBJECTIVETo study the effect of electro-acupuncture (EA) at points along Foot Yangming Channel on metabolite of ulcerative colitis (UC) rats' cerebral cortex and to identify key metabolites by referring to Pi/Wei-brain related theory in Chinese medicine (CM).

METHODSThe UC rat model was set up by dextran sulfate sodium (DSS) method. Male SD rats were randomly divided into the model group and the EA group, 13 in each group. Another 13 rats were recruited as the blank control group. Rats in the blank control group and the model group received no EA. EA was performed at Zusanli (ST36), Shangjuxu (ST37), and Tianshu (ST25) for 5 days by using disperse-dense wave. Then all rats were sacrificed. Their recto-colon and the ileocecal junction were pathomorphologically observed by light microscope and transmission electron microscope (TEM). Cerebral cortexes were extracted. Water-soluble and lipid-soluble brain tissue metabolites were respectively extracted for metabolic research using 1H nuclear magnetic resonance (1H-NMR).

RESULTSEA could obviously improve the general condition of UC model rats, decrease the value of DAI, reduce the infiltration of inflammatory cells in the intestinal tract, stabilize structures such as mitochondria, endoplasmic reticulum and so on (P <0.05). 1HNMR analysis showed that in the model group, contents of glutamic acid, cholesterol, very low density lipoproein (VLDL) in the pallium obviously decreased, while alanine and low density lipoprotein (LDL) significantly increased. After EA, levels of lactic acid, glutamic acid, total cholesterol (TC), and VLDL all increased, and levels of alanine and LDL decreased. All indices were approximate to those of the blank control group.

CONCLUSIONEA at Foot Yangming channel was found to have some effect on metabolites in the brain tissue of UC model rats, which had specific metabonomic material basis and mechanism based on the Pi/Wei-brain related theory.

Objective To investigate the characteristics of renal hemodynamic and the esoteric prostacyclin(PGI2),thromboxane A2(TXA2)level in children with early Henoch-Schonlein purpura(HSP),and study the function of TXB_2/6-Keto-prostaglandin F(6-Keto-PGF_(1?))(T/K)numerus in early changes of kidney injury.Methods Children involved in the experiment were dicided into 3 groups.Thirty-one patients with HSP,divided into 2 groups according to routine urianlysis:children with HSP without renal damage group(n=16)and Henoch-Schonlein purpura nephritis(HSPN)group(n=15).Control group with 16 healthy children,their age and sex match with the other 2 groups.The urine of all children,including the children in control group,was sampled in 24 hours.The urinary production of the samples were kept in the freezer at-20 ℃.The radioimmunoassay was applied to determine the 6-Keto-PGF_(1?),TXB_2 quantitatively,and calculate the number of T/K.In the early morning the children accept the Doppler arteria renalis sonography with an empty stomach to determine the Vmax of the period of contraction of the arteria renalis the Vmin of diastolic phase and the resistent index(RI).SPSS 13.0 software was used to analyze the data.Results 1.The renal hemodynamic indicated a change of high velocity and resistance,the masculine rate(83.9%)was ob-viously higher than that in routine urinalysis(48.4%)(?2=5.79 P0.05).The RI in the former group(0.798?0.165)was much higher than that in the other one(0.637?0.116)(t=4.02 P

Objective To investigate the expression and significance of Caspase-3 and Survivin at different stages of human hemangioma in children.Methods Fifty-five specimens of hemangioma tissue excised in operation and 8 normal skins removed in operation were harvested from People's Hospital of Gansu Province between Jan.2000 and Dec.2005.The pathologic diagnosis was divided into 3 groups according to Mulliken's standard under microscope:proliferated phase group(n=31),degenerated phase group(n=24),and control group(n=8).All these specimens were examined by immunohisto for Caspase-3 and Survivin expression.Results Caspase-3 positive rate in the proliferative phase and involuting phase were 35.5% and 79.2%,respectively.The positive rate in involuting phase was higher than that that in proliferative phase,the difference between the 2 groups was significant(P=0.045 9).A significant difference was not found between the proliferative phase and normal skin tissue(P=0.057 3).Survivin positive rate in the proliferating and involuting phase were 77.4% and 45.8%,respectively.The positive rate in proliferative phase was higher than that in involuting phase,the difference between the 2 groups was significant(P=0.008 5),the difference in involuting phase and normal skin tissue was not significant(P=0.059 3).Conclusions High level of Caspase-3 expression in vascular endothelial cells in involuting phase in contrast to that in proliferative phase,which indicates that Caspase-3 may play a positive role in the apoptosis of vascular endothelial cells.Survivin may inhibit the apoptosis of vascular endothelial cells in proliferative phase due to it's high expression.Caspase-3 and Surivivin involved in the hemangioma in the regulation of apoptosis.J Appl Clin Pediatr,2009,24(1):51-52

OBJECTIVETo investigate the toxic effect of sodium fluoride (NaF) on the nematode Caenorhabditis elegans (C. elegans).

METHODSAdult C. elegans were exposed to different concentrations of NaF (0.038 mmol/L, 0.38 mmol/L, and 3.8 mmol/L) for 24 h. To assess the physiological effects of NaF, the brood size, life span, head thrashes, and body bend frequency were examined. Reactive oxygen species (ROS) and cell apoptosis were detected as parameters of biochemical response. The gene expressions were determined by real-time polymerase chain reaction (PCR) to assess the molecular-level response.

RESULTSAt the physiological level, the brood size of C. elegans exposed to 0.038 mmol/L, 0.38 mmol/L, and 3.8 mmol/L concentrations of NaF were reduced by 6%, 26%, and 28% respectively in comparison with the control group. The maximum life spans of C. elegans exposed to 0.038 mmol/L, 0.38 mmol/L, and 3.8 mmol/L concentrations of NaF were reduced by 3 days and 5 days, respectively. Head thrashes and body bend frequency both decreased with increasing concentrations of NaF. At the biochemical level, the production of ROS and the incidence of cell apoptosis increased with increasing concentrations of NaF (P < 0.05). At the molecular level, different concentrations of NaF exposure raised the expression of stress-related genes, such as hsp16.1, sod-3, ctl-2, dhs-28, gst-1, and cep-1.

CONCLUSIONNaF exposure could induce multiple biological toxicities to C. elegans in a concentration-dependent manner. These toxicities may be relevant to the oxidative stress induced by increased ROS production and accumulation in C. elegans.
