This study was aimed to compare different preparation methods of Wei-Chang Fu-Yuan (WCFY) De-coction, which is a self-made traditional Chinese medicine (TCM) decoction of our hospital, through the investiga-tion of difference in recovery time of gastrointestinal function after gynecological abdominal surgery. A total of 120 cases after gynecological abdominal surgery in our hospital between 2011 and 2012 were randomly divided into the treatment group and the control group, with 60 cases in each group. The hospital self-made WCFY Decoction was given to patients 8 hours after surgery in the treatment group and control group. Decoctions given to two groups were prepared with different methods. Decoction given to the treatment group was by the decoction ma-chine of multiple decoctions preparation. Decoction given to the control group was prepared as the traditional sin-gle dose decoction. The first anus flatus time was observed in both groups. The results showed that the flatus time of treatment group was 16 h and that of the control group was 13 h. The flatus time of patients from two groups was in skewed distribution, so the distance between the median and quartile was used to describe. The non-para-metric tests (Kolmogorov-Smirnov method) were used in the comparison of flatus time of two groups. There was statistical significance between two groups (P < 0.05). It was concluded that different preparation methods affect the clinical efficacy of WCFY Decoction. Compared with the traditional single dose decoction, the fist flatus time was postponed 3 hours by the decoction machine of multiple decoctions preparation. Therefore, with the widely using of decoction machine of multiple decoctions preparation today, the function of decoction machine should be improved and the program should be perfected in order to increase the clinical efficacy of this preparation method.

Objective To report the MRI findings of brain damage obsenrved in neonatal patients who suffered from isolated hypoglycemia and to explore the value of diffusion-weighted imaging(DWI) inearly detection of neonatal hypoglycemic brain iniun,. Methods Twelve neonates with isolated hypoglycemia(10 of the 12 were diagnosed to suffer from hypoglycemic encephalopathy)were enrolled in this study.They were first scanned at age from 3 days to 10 days with Tl WI,T,WI and DWI(b is 0 s/mm2,1000 s/mm2),and 4 of them were then scanned from 7 days to 10 days following the initial scan.All acquired MR images were retrospectively analysed.Results First series of DWl images showed distinct hyperintense signal in 11 cases in several areas including bi lateral occipital cortex(2 cases),right occipital cortex(1 case),left occipital cortex and subcortical white matter(1 case),biIateral occipital cortex and flubcortical white matter(2 cases),bilateral parieto-occipital cortex(2 cases),bilateral parieto-occipital cortex and subcortical white matter(2 cases),the splenium of corpus catlosum(4 cases),bilateral corona radiata(2 cases),left eaudate nucleus and globus pallidus(1 case),bilateral thalamus(1 case),bilaterally posterior limb of internal capsule(1 ease).In the initial T1 WI and T2,WI images,there were subtle hypointensity in the damaged cortical areas(3 cases),hyperintensity in the bilaterally affected occipital cortex(1 case)on T1 weighted images,and hyperintensity in the affected cortex and subcortieal white matter with poor differentiation on T2 weighted images.The followed-up MRI of 4 cases showed regional encephalomalaeia in the affected occipital lobes(4 cases),slightly hyperintensity on T2 weighted images in the damaged occipital cortex(2 cases),extensive demyelination(1 case).disappearance of hyperintensity of the splenium of corpus callosum(1 case),and persistent hyperintensity in the splenium of corpus callosum (1 case)on T2 weighted images.Conclusion The findings suggest that posterior parieto-occipital regions are most frequently injured in neonatal period due to severe hypoglycemia.DWI is a useful technique in the early detection and evaluation of hypoglycemic brain injury of neonates.

Objective To elucidate the efficacy and possible mechanism of Qingchang mixture in ameliorating postoperative abdominal adhesions in rats.Methods Seventy-five Sprague-Dawley rats were randomly allocated into five experimental groups:the control group,the sham-operated group,the model group,the Qingchang mixture treatment group and the sodium hyaluronate treatment group.Except the control group and the sham-operated group,the other three groups were treated with cecal abrasion method to establish the rat model of abdominal adhesion.In the sodium hyaluronate group,2 mL sodium hyaluronate gel was meticulously applied to the injured abdominal wall and cecum prior to abdominal closure.Following successful establishment of adhesion model,the Qingchang mixture group received a daily oral gavage of 2 mL Qingchang mixture(14.58 g/kg),while the other four groups were given equal volume normal saline administration.In each group,five rats were euthanized on postoperative days 3,7 and 14 to assess abdominal adhesions using Nair's scoring system.Adhesive tissue or normal peritoneal tissue were harvested on postoperative day 7,and mRNA expression levels of interleukin-4(IL-4),signal transducer and activator of transcription 6(STAT-6)and interferon-γ(IFN-γ)were quantified via fluorescence-based real-time PCR.Concurrently,Western blot analysis was employed to evaluate protein expression levels of IL-4,interleukin-10(IL-10),STAT-6 and IFN-γ.Pathological alterations in adhesive tissue were visualized using hematoxylin-eosin(HE)staining under light microscopy,and inflammation and fibrotic changes were assessed accordingly.Results Compared with the blank and sham-operated groups,mRNA and protein expression levels of IL-4 and STAT-6 were significantly downregulated in the model group,protein expression level of IL-10 was also reduced.Conversely,the mRNA and protein expression levels of IFN-γ,as well as the inflammation and fibrosis scores were significantly elevated(P＜0.05).In comparison to the model group,IL-4 and STAT-6 mRNA and protein expression levels were increased in the Qingchang mixture group and the hyaluronic acid group,along with an increase in IL-10 protein expression.Conversely,these groups exhibited a significant reduction in Nair's scores,inflammation scores,fibrosis scores,and IFN-γ mRNA and protein expression levels were decreased(P＜0.05).Conclusion Qingchang mixture appears to suppress the development of postoperative peritoneal adhesions,likely through mechanism that involves modulating the expression of T-helper 1 and T-helper 2 cytokines,thereby attenuating inflammatory response.

OBJECTIVE To evaluate the quality of Lycopodium japonicum from different producing areas. METHODS Sixteen batches of L. japonicum from six provinces were used as samples. The contents of α -obscurine， β -obscurine， lycopodine， lycodoline， lyclaninol， 21-episerratenediol， stigmasterol and β-sitosterol in L. japonicum were detected by quantitative analysis of multi-components by single-marker （QAMS）. The results were compared with the results of external standard method. The extract and total ash were measured according to the appendix of Chinese Pharmacopoeia. Principal component analysis， orthogonal partial least squares-discriminant analysis and weighted technique for order preference by similarity to ideal solution （TOPSIS） methods were combined to evaluate its quality. RESULTS The contents of lyclaninol in the 16 batches of L. japonicum were 0.183-0.446 mg/g. Using lyclaninol as internal reference material， the contents of α-obscurine， β-obscurine， lycopodine， lycodoline， 21-episerratenediol， stigmasterol and β-sitosterol were 1.250-2.097， 0.690-1.184， 0.035-0.102， 0.076-0.150， 0.356-0.570， 0.085-0.229 and 0.238-0.855 mg/g， respectively， with no significant difference from the results of external standard method. The extract was 12.18%-22.78%， and the total ash was 3.16%-6.11%. Principal component analysis showed that samples S1-S6，S7-S11，S12-S16 could be clustered into 3 categories. The variable importance in projection values for α-obscurine， β-sitosterol， lyclaninol， β-obscurine and 21- episerratenediol were all greater than 1. The weighted TOPSIS evaluation results showed that sample S14 had the best quality （Jb＝ 0.709 2）. CONCLUSIONS L. japonicum from Suijiang county of Yunnan province had the best quality. The established QAMS combined with chemometric and weighted TOPSIS methods can be used for quality evaluation of L. japonicum from different producing areas.
