To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

Objective To realize the myosin heavy chain(MHC) expression and related factors in severe pneumonia.Methods The staphylococcus aureus peumonia models of 30 Wistar rats were established and other 20 rats as control group.MHC expression and myocardial histopathologic score and cardiac function were examined.Results The expression of ?-MHC mRNA were lower in the rats with peumonia than that in the control group,while the expression of ?-MHC mRNA in the cases with peumonia increased significantly.The relative contents of ?-MHC mRNA had negative correlation with myocardial histopathologic score and had positive correlation with EF,FS.The relative contents of ?-MHC mRNA had positive correlation with myocardial histopathologic score and had negative correlation with EF,FS.Conclusions The cases with severe peumonia have abnormal expression of MHC,with the transformation of ?-MHC to(?-MHC).These proved that severe pneumonia can complicated with heart failure from gene level.

This article was aimed to study the sedative and hypnotic effects of different eluents of Shuangxiatang (SXT). The effects of SXT water decoction, water eluent, 20%, 70% and 95% alcohol eluent on spontaneous ac-tivity and the sleeping induced by subthreshold dose of pentobarbital sodium were measured. The results showed that the SXT decoction, 20% and 95% alcohol eluent can significantly decrease the number of rearing in mice with the percentage of 78.5%, 78.3% and 62.5%, respectively. SXT water eluent and 70% alcohol eluent can significantly decrease the spontaneous activity of mice (P < 0.01), the number of rearing (P < 0.01) and grooming time (P < 0.05). SXT water decoction can significantly shorten sleep latency (P < 0.05), prolong sleep time (P <0.05), and increase rates of sleeping in mice. SXT water eluent can significantly shorten sleep latency in mice (P< 0.05), increase rates of sleeping in mice. SXT water decoction and water eluent have the sedative and hypnotic effects. And the effects are more than alcohol eluents.

To investigate the effects of 2-(4-methoxycarbonyl-2-tetradecyloxyphenyl)carbamoylbenzoic acid (CX09040) on protecting pancreatic β cells, the β cell dysfunction model mice were induced by injection of alloxan into the caudal vein of ICR mice, and were treated with compound CX09040. Liraglutide was used as the positive control drug. The amount and the size of islets observed in pathological sections were calculated to evaluate the β cell mass; the glucose stimulated insulin secretion (GSIS) test was applied to estimate the β cell secretary function; the oral glucose tolerance test (OGTT) was taken to observe the glucose metabolism in mice; the expressions of protein in pancreas were detected by Western blotting. The effects on the target protein tyrosine phosphatase 1B (PTP1B) were assessed by the PTP1B activities of both recombinant protein and the intracellular enzyme, and by the PTP1B expression in the pancreas of mice, separately. As the results, with the treatment of CX09040 in alloxan-induced β cell dysfunction mice, the islet amount (P<0.05) and size (P<0.05) increased significantly, the changes of serum insulin in GSIS (P<0.01) and the values of acute insulin response (AIR, P<0.01) were enhanced, compared to those in model group; the impaired glucose tolerance was also ameliorated by CX09040 with the decrease of the values of area under curve (AUC, P<0.01). The activation of the signaling pathways related to β cell proliferation was enhanced by increasing the levels of p-Akt/Akt (P<0.01), p-FoxO1/FoxOl (P<0.001) and PDX-1 (P<0.01). The effects of CX09040 on PTP1B were observed by inhibiting the recombinant hPTP1B activity with IC50 value of 2.78x 10(-7) mol.L-1, reducing the intracellular PTP1B activity of 72.8% (P<0.001), suppressing the PTP1B expression (P<0.001) and up-regulating p-IRβ/IRβ (P<0.01) in pancreas of the β cell dysfunction mice, separately. In conclusion, compound CX09040 showed significant protection effects against the dysfunction of β cell of mice by enlarging the pancreatic β cell mass and increasing the glucose-induced insulin secretion; its major mechanism may be the inhibition on target PTP1B and the succedent up-regulation of β cell proliferation.

BACKGROUNDThe treatment for long bone defects has been a hot topic in the field of regenerative medicine. This study aimed to evaluate the therapeutic effects of calcium sulfate (CS) combined with platelet-rich plasma (PRP) on long bone defect restoration.

METHODSA radial bone defect model was constructed through an osteotomy using New Zealand rabbits. The rabbits were randomly divided into four groups (n = 10 in each group): a CS combined with PRP (CS-PRP) group, a CS group, a PRP group, and a positive (recombinant human bone morphogenetic protein-2) control group. PRP was prepared from autologous blood using a two-step centrifugation process. CS-PRP was obtained by mixing hemihydrate CS with PRP. Radiographs and histologic micrographs were generated. The percentage of bone regenerated bone area in each rabbit was calculated at 10 weeks. One-way analysis of variance was performed in this study.

RESULTSThe radiographs and histologic micrographs showed bone restoration in the CS-PRP and positive control groups, while nonunion was observed in the CS and PRP groups. The percentages of bone regenerated bone area in the CS-PRP (84.60 ± 2.87%) and positive control (52.21 ± 4.53%) groups were significantly greater than those in the CS group (12.34 ± 2.17%) and PRP group (16.52 ± 4.22%) (P < 0.001). In addition, the bone strength of CS-PRP group (43.10 ± 4.10%) was significantly greater than that of the CS group (20.10 ± 3.70%) or PRP group (25.10 ± 2.10%) (P < 0.001).

CONCLUSIONCS-PRP functions as an effective treatment for long bone defects through stimulating bone regeneration and enhancing new bone strength.

OBJECTIVETo determine the correlation of the CYP1A1 (rs4646422) gene polymorphisms with male infertility in the Chinese Han population.

METHODSUsing the Mass ARRAY iPLEX GOLD technique, we conducted a case-control study on theCYPlA1 (rs4646422) gene polymorphisms in 636 infertile males aged 21-49 years (case group) and 442 normal healthy men aged 23-47 years (control group) of the Chinese Han population. We analyzed the genotypes and allele frequencies in the two groups ofsubjects with the SPSS 20.0 software.

RESULTSCompared with the wild homozygous genotype GG, the heterozygous genotype AG (OR = 1.06, 95% CI 0.81-1.38) and homozygous genotype AA (OR = 1.11, 95% CI 0.56-2.21) showed no correlation with male infertility, nor did the mutant allele A (OR = 1.06, 95% CI 0.85-1.32) in comparison with the wild allele G.

CONCLUSIONThe CYP1A1 (rs4646422) gene polymorphisms might not be correlated with male infertility in the Chinese Han population.

OBJECTIVETo verify the regulation of acyl-coenzyme A:cholesterol acyltransferase 2 (ACAT 2), which is associated with cholesterol metabolism, by saturated fatty acids (SFAs).

METHODSPalmitic acid (PA), the most abundant saturated fatty acid in plasma, and oleic acid (OA), a widely distributed unsaturated fatty acid, were used to treat hepatic cells HepG2, HuH7, and mouse primary hepatocytes. In addition, PA at different concentrations and PA treatment at different durations were applied in HepG2 cells. In in vivo experiment, three-month male C57/BL6 mice were fed with control diet and SFA diet containing hydrogenated coconut oil rich of SFAs. The mRNA level of ACAT2 in those hepatic cells and the mouse livers was detected with real-time polymerase chain reaction (PCR).

RESULTSIn the three types of hepatic cells treated with PA, that SFA induced significant increase of ACAT2 expression (Pü0.01), whereas treatment with OA showed no significant effect. That effect of PA was noticed gradually rising along with the increase of PA concentration and the extension of PA treatment duration (both Pü0.05). SFA diet feeding in mice resulted in a short-term and transient increase of ACAT2 expression in vivo, with a peak level appearing in the mice fed with SFA diet for two days (Pü0.05).

CONCLUSIONSFA may regulate ACAT2 expression in human and mouse hepatic cells and in mouse livers.
