Gentianae Urnulae Herba, dried whole herb of Gentiana urnula,is a commonly used Tibetan medicine. However, only the character identification is used as quality control standard officially at present. As a part of project for the Chinese Pharmacopoeia (2015 edition), the quality standard of this species was established in this study. The tests of water content, total ash, acid-insoluble ash and ethanol-soluble extractives of the crude drugs were carried out following the methods recorded in appendix of Chinese Pharmacopeia (2010 edition, volume 1). The TLC identification method was established by using gentiournoside A as reference substance, and a mixture of ethyl acetate-methanol-water-formic acid(7:1. 5:1: 0. 2) as the developing solvent system on silica gel G TLC plate. The content of gentiournoside A was assayed by HPLC on an Agilent Zorbax SB-C18 (4.6 mm x 250 mm,5 μm) column, using acetonitrile-water (0.1% phosphoric acid) (26:74) as the mobile phase at a flow rate of 1.0 mL x min(-1). The column temperature is at 30 degrees C and the detection wavelength is at 240 nm. As a result, gentiournoside A and the other constituents were separated and presented the same fluorescence light comparing with the reference substance on TLC detected under the UV light(366 nm). The methodology validation for the assay of gentiournoside A showed that it was in a good linear correlation in the range of 0.009 95-0.398 g x L(-1) with the regression equation of Y = 1 467.1X +41.407(r = 0.999 9), and the average recovery was 98. 3% (RSD 2.2%). The mass fractions of gentiournoside A, water content, ethanol-soluble extractives of 15 batches samples were varied in the ranges of 0.175% -1.83%, 8.60% - 9.93% and 29.2% - 35.2%, respectively. Total ash and acid-insoluble ash were 10.2% - 17.2% and 5.26% - 10.8% detected from 10 batches samples. The recommended standards of quantitative indexes are that the mass fractions of gentiournoside A and extractives are not less than 0.80% and 26.0%, respectively; the water, total ash and acid-insoluble ash are not more than 12.0%, 15.0% and 8.0%, respectively.

OBJECTIVETo observe the effect of Ganoderma lucidum decoction in treating Russula subnigricans poisoning (RSP) patients.

METHODSThe 14 patients of RSP in the treated group were treated with GLD (GLD, one dose was prepared by 100 g of Ganoderma lucidum decocted with water to 600 ml), on the base of conventional treatment, and 11 patients received conventional therapy in the previous year were taken as control. The clinical efficacy and parameters in them were compared, including the urine N-acetyl-D-glucosaminidase (NAG, which reflects the injury of kidney), the red blood cell and protein in urine, the alanine transaminase (ALT, which reflects the injury of liver), and the aspartate aminotransferase (AST, which reflects the injury of heart).

RESULTSA better clinical cure-markedly improving rate was showed in the treated group as compared with the control group, P < 0.01. In the treated group, red blood cell in urine disappeared after 24 hrs treatment in the majority of patients, urinary protein reduced obviously and the other three parameters reached the peak at the 3rd day then lowered gradually. In the control group, all the parameters increased continuously. Comparison between the parameters at corresponding time in the two groups showed significant difference (P < 0.01), those in the treated group were markedly lower than those in the control group respectively.

CONCLUSIONGLD has good effect in treating RSP, could obviously lower the fatat rate of RSP.

The CO I gene sequences of Qianghuoyu, Pachytriton labiatus and Gehyra mutilata were achieved by PCR amplification and bi-directional sequencing. Furthermore, a pair of specific primers SJYW1 and SJYW2 in the non-conservative district were designed through sequence alignment. The PCR reaction condition was established by changing the annealing temperature and cycle numbers. The results showed that 350 bp DNA fragment was amplified from Qianghuoyu in PCR with annealed temperature at 54 °C and the cycle number was 25 cycles, whereas not any DNA fragment was amplified from P. labiatus and G. mutilata under the same reaction condition. This method is well-performed in the identification of Qianghuoyu for its excellent specificity and repeatability.

OBJECTIVEThe three-dimensional (3D) craniofacial measurements were studied through the quantitative computed tomography (CT). The dynamic database of quantitative measurement of three-dimensional craniofacial bone was established as mandible in physiological position.

METHODS170 aesthetics female were examined by spiral volumetric CT (GE SR-7000). 3D craniofacial bone images were reformatted and 3D measurements were performed in SUN Workstation respectively. 33 points were defined in the 3-d craniofacial structure in screen, 14 distances and 11 angles were measured, and 12 ratios were calculated in each case. All data were transferred into the database based on the SPSS software. There is all information of one case (such as number, sex, age, distances, angers) in one row; each column is a measurement item. The mean, standard deviation, standard error, medium, coefficient of variation and 95% confidence interval of data can be calculated and the correlation, regression between several groups of measurement item can be proceeded by computer automatically in the dynamic database.

RESULTS3D craniofacial bone imagings were displayed in arbitrary views without disturbing superposition by using cutting, rotating and 3D measurement procedures. The large data volume provides more information of special relationship of skull base, zygomatic bone, maxilla, mandible and vertebra. The coefficient of variation of skull base is less than them of maxilla and mandible. The standard deviation of ratios is further smaller than the standard deviation of distances and angles. With stepwise regression, the equation is (Go - Go) Y = 0.578X1 + 0.754X2 + 0.228X3 - 0.579X4 - 14.672; (Tz- Tz) : Y = 0.775X1 + 0.161X2 + 0.348X3 + 0.201X4 + 27.730.

CONCLUSIONSThe database offers reference of the studying of growth rule of craniofacial bone of aesthetics female. It will help improve diagnostic accuracy, staging of reconstruction, precision of corrective surgery, and follow-up patients.

Comparative analysis of variable region ORF14/15 genes of white spot syndrome virus (WSSV) genome in Guangxi Penaeus vannamei (P. vannamei) could provide useful information for the evaluation of genetic diversity and genetic evolutionary relationship among WSSV isolates from Guangxi, China and other places. Based on geographical and temporal considerations, 40 WSSV-positive P. vannamei samples were collected during the period between May 2010 and July 2013 from Beihai, Qinzhou, and Fangchenggang, which were the main P. vannamei production areas in Guangxi, and the variable region ORF14/15 genes of the WSSV genome from all infected samples were amplified by PCR and then subjected to cloning and sequence analysis. Pairwise and multiple alignment analysis was then conducted to evaluate the degree of genetic divergence between different strains. The variable region ORF14/15 genes from 25 of 40 WSSV positive samples were successfully cloned and sequenced; among the ORF14/15 genes of 25 WSSV-positive strains, 22 was 619 bp in length and 3 was 620 bp. All the 25 Guangxi strains carried a 5949-bp deletion in the ORF14/15 region relative to TH-96-II, which has the longest nucleotide sequence in this region; the deletion of Guangxi strains occurred in the middle region of ORF14/15 gene, with only 190 bp and 429 bp/ 430 bp at 5' and 3' ends, respectively, which were coincident with WSSV-IN-05-I in deletion length and position. Sixteen of 25 Guangxi strains had completely identical nucleotide sequences in the variable re gion, and the homology between other strains also exceeded 97.9%. There were single nucleotide substi tution, deletion, and insertion in the ORF14/15 region of Guangxi strains compared with other strains in GenBank. In the phylogenetic tree based on WSSV variable region ORF14/15, the Guangxi strains were closely related and formed a separate branch with Indian strain IN-05-I, but far from other strains in GenBank. The ORF14/15 gene of WSSV isolates in cultured P. vannamei in Guangxi has a large deletion in the middle of the variable region, and the Guangxi WSSV strains show no significant spatio-temporal differences; the Guangxi strains are closer in genetics to Indian strain IN-05-I than other strains in GenBank.

OBJECTIVETo assess the effects of treatment of Amanita mushroom poisoning with Glossy anoderma Decoction (, GGD).

METHODSTwelve patients with acute Amanita mushroom poisoning received conventional treatment (penicillin and reduced glutathione) combined with oral administration of GGD (treated group), which was prepared out of 200 g Glossy ganoderma decocted in water to 600 mL, and 200 ml was given once, three times a day for 7 successive days; while conventional treatment alone was given to the other 11 patients assigned to the control group. The therapeutic efficacy and changes in serum levels of total bilirubin (TBil), bile acids (BA), alanine transaminase (ALT), and aspartate transaminase (AST) activities in the two groups were compared.

RESULTSThe cured-markedly effective rate in the treated group was more significant than that in the control group (P<0.01). Elevation in TBil, BA, ALT, and AST activities were observed in both groups 3 days after poisoning, which progressively increased thereafter in the control group. In the treated group, they reached their peak on the 3rd day and then declined gradually. The differences between pre-treatment and post-treatment in both groups were obviously significant (P<0.01), so were the differences between the two groups at corresponding time points (P<0.01).

CONCLUSIONGGD shows excellent clinical efficacy in the treatment of acute Amanita mushroom poisoning and can reduce mortality significantly.

OBJECTIVETo study the pathologic features, differential diagnosis and role of open lung biopsies (OLB) in usual interstitial pneumonia (UIP).

METHODThe authors reviewed the pathologic, clinical and radiologic features of five cases of UIP (one autopsy case and four OLB cases), with follow-up information.

RESULTSThe typical histologic features were a non-uniform distribution of alveolar inflammation, fibroblastic foci, interstitial fibrosis and honeycomb change. There also was associated metaplasia of bronchiolar epithelium, type II pneumocyte hyperplasia and accumulation of alveolar macrophages.

CONCLUSIONSCharacteristically, UIP exhibits temporal heterogeneity under low-power light microscopy, which includes changes in both the early and end stages. Open lung biopsy is an important diagnostic adjunct for suitable patients with atypical radiologic features on computerized tomography. Correlation between clinical, radiologic and pathologic findings is also essential for a correct diagnosis.
