China Journal of Chinese Materia Medica 2014;39(6):1107-1110
The experiment was designed to study the mechanism of increasing efficiency of Ligustrum lucidum steamed with wine. Rats in vivo with gastrointestinal perfusion model were used. The contents of salidroside and specnuezhenide in the fluid of gastrointestinal perfusion of rats were measured by HPLC at different time points after dosing. Then the K(a) and absorption percentage were calculated. Specnuezhenide could be detected in the fluid of gastrointestinal perfusion of specnuezhenide. The K(a) of the specnuezhenide and salidroside in the fetal intestines are 0.055 3 and 0.144 2 h(-1) respectively and the total absorptivity are 24.46% and 60.14% respectively after 4 hours. The K(a) in the stomach are 5.70 and 8.26 h(-1) respectively and the total absorptivity are 34.21% and 47.23% respectively after 4 hours. The experiment proved that specnuezhenide can be metabolized into salidroside which is more beneficial for gastrointestinal absorption. The experiment proved that specnuezhenide can be metabolized into salidroside both in the rat's stomach and the fetal intestine and compared with the specnuezhenide salidroside is more conducive to gastrointestinal absorption. The results suggested that the increasing efficiency on liver and kidney of L. lucidum steamed with wine has business with the fact that Specnuezhe nide is more conducive to the body after it is changed into salidroside.

By using whole blood selenium, 24 hr urinary selenium and hair selenium contents as the indices of assessing human selenium status, it was found that the populations in the endemic areas of Keshan disease were practically in a selenium poor status. The selenium contents in locally grown staple grains and daily diets in the endemic areas were also lower than those in the non-endemic areas. In an area covering a cross section of Keshan disease geographic belt in our country, the hair selenium contents of agricultural populations were measured. The results indicated that all the hair selenium contents in the endemic sites were always at a lower level, whereas those in the non-endemic sites distant from the endemic areas were generally at a higher level; they decreased gradually until the endemic areas were reached; and finally, along the contiguous region of the endemic and non-endemic areas they were insignificantly different.The hair selenium contents among the agricultural populations were significantly lower than those among the non-agricultural ones in the same endemic areas. However, no regular correlation had been observed between the seasonal prevalence of Keshan disease and the variation of hair selenium contents in the same populations living in the same endemic sites.It is considered that the endemic areas of the disease seem to be a Se-deficiency belt, and Se-deficiency probably might be a pathogenic geo-gen in the prevalence of Keshan disease.

Glutathione is a tripeptide comprised by L-glutamate, L-cysteine, and glycine, that serves antioxygenation and deintoxication functions within the cell. Recent study has found that glutathione is the main driving force for bile salt-independent bile flow, impaired biliary excretion of glutathione can lead to cholestasis. This review focuses on hepatobiliary transport of glutathione and its role in cholestasis. Based on the evidence of choleretic effect of glutathione, enhancement of biliary excretion of glutathione may be a good strategy for prevention and treatment of cholestasis.

In the present experiments, the characteristics of the electrical responses to stimulation of the cerebellum in crucian carp Mauthner cell were explored with microeletrode intracellular recording technique. A composite excitatory postsynaptic potential (cerebellum-evoked EPSP) could be induced from the soma, the ventral dendrite and the proximal end of the lateral dendrite in crucian carp Mauthner cell (M-cell) on either side by stimulation of the ventrolateral region of the cerebellum. The cerebellum-evoked EPSP presented characteristics of relatively short latency (0.63+/-0.09 ms), longer duration (5.49+/-1.13 ms), graded amplitude and dependence on stimulation frequency. Stimulation of the cerebellum with higher intensity always activated the M-cell orthodromically. Multiple intracellular recordings showed that the cerebellum-evoked EPSP originated in the distal end of the ventral dendrite. The results suggest that the cerebellum-M-cell pathway is probably composed of a group of neuron chains with different numbers of synaptic relays projecting to the distal end of the ventral dendrite in order of length of the chains.

This study was aimed to detect the methylation status of FHIT gene promoter region in the DNA from plasma of patients with myelodysplastic syndrome (MDS), and to investigate the demethylating effect of decitabine. Methylation-specific PCR method was used to detect the methylation status of FHIT gene promoter region in the DNA from plasma of 4 patients with MDS before and after treatment with decitabine plus semis CAG therapy (among them, 1 case of newly diagnosed MDS, 3 cases progressed into acute leukemia). The results indicated that 3 cases were found to have an increased methylation in the promoter region. After treatment with decitabine plus semis CAG, increased methylation was reversed in 2 cases. In 4 cases, 2 cases displayed clinical response. It is concluded that FHIT gene hypermethylation is associated with MDS pathogenesis. Decitabine has demethylating effect on the FHIT gene hypermethylation of plasma from MDS patients. Detecting the methylation status of FHIT gene in DNA from plasma may play a role in MDS auxiliary diagnosis or prognosis.

OBJECTIVETo study the short-term response and tolerance of different doses of amino acids in parenteral nutrition among preterm infants.
METHODSThis study included 86 preterm infants who had a birth weight between 1 000 to 2 000 g and were admitted to the hospital within 24 hours of birth between March 2013 and June 2014. According to the early application of different doses of amino acids, they were randomized into low-dose group (n=29, 1.0 g/kg per day with an increase of 1.0 g/kg daily and a maximum of 3.5 g/kg per day), medium-dose group (n=28, 2.0 g/kg per day with an increase of 1.0 g/kg daily and a maximum of 3.7 g/kg per day), and high-dose group (n=29, 3.0 g/kg per day with an increase of 0.5-1.0 g/kg daily and a maximum of 4.0 g/kg per day). Other routine parenteral nutrition and enteral nutrition support were also applied.
RESULTSThe maximum weight loss was lower and the growth rate of head circumference was greater in the high-dose group than in the low-dose group (P<0.05). The infants in the medium- and high-dose groups had faster recovery of birth weight, earlier attainment of 100 kcal/(kg·d) of enteral nutrition, shorter duration of hospital stay, and less hospital cost than those in the low-dose group (P<0.05). Blood urea nitrogen (BUN) levels in the high-dose group increased compared with the other two groups 7 days after birth (P<0.05). The levels of creatinine, pH, bicarbonate, bilirubin, and transaminase and the incidence of complications showed no significant differences between groups (P>0.05).
CONCLUSIONSParenteral administration of high-dose amino acids in preterm infants within 24 hours after birth can improve the short-term nutritional status of preterm infants, but there is a transient increase in BUN level.

This study was aimed to investigate the expression and clinicopathologic significance of Gli1 and Gli2, 2 factors of Hedgehog(Hh) signaling pathway, in non-Hodgkin's lymphoma (NHL). Gli1 and Gli2 mRNA and protein in 18 cases of NHL and 10 cases of reactive lymphadenitis were amplified and identified by real-time PCR, and were assayed by immunohistochemical staining respectively. The results showed that (1) Gli1 and Gli2 mRNA in NHL group (RQ 2.05, 2.31) were expressed higher than that in reactive lymphadenitis group (RQ 0.82, 0.89). Gli1 mRNA activated level was positively related with Gli2 (r = 0.63, p < 0.01). In addition, Gli2 also positively correlated to clinical stages of NHL (p = 0.03), but the expressions of Gli1 and Gli2 mRNA had no significant correlation to B symptoms, blood β(2)-microglobulin, age and sex. (2) The positive expression rate of Gli1 and Gli2 protein in NHL group were 80% and 68% respectively, which were extremely higher than that in reactive lymphadenitis group. Gli1 protein level was positively related with Gli2 (r = 0.62, p < 0.05). Both Gli1 and Gli2 protein expression positively correlated to clinical staging of NHL (p = 0.05, p = 0.01). It is concluded that the Gli1 and Gli2 of Hh signaling pathway have been found to higher express in patients with NHL, and have significance for clinical staging and predicting prognosis of NHL. To further investigate the role of Hh signaling pathway in NHL will contribute to elucidate the occurrence and development of NHL, and provide a favorable method for therapy of NHL.
