Gingival fibromatosis is a rare disease, especially its syndromic form. Here, we review the literatures on gingival fibromatosis and briefly summarize some characters on clinical, etiological, genetic and histopathological aspects. We also present a rare case of gingival fibromatosis with multiple unusual findings in a 21-year-old man. And we differentiate it from some well-known syndromes including gingival fibromatosis. Maybe it implies a new syndrome within the spectrum of those including gingival fibromatosis.

Objective To evaluate prourodynamic study and somatosensory evoked potentials(SEPs)before and after operation of children with lipomyelomeningocele(LMMC)and its clinical significance.Methods Urodynamic study(UDS)and SEPs in 31 cases of LMMC who underwent microsurgical release within 1 week preoperatively and 3 months postoperatively were conducted.The 4 parameters used for UDS evaluation were bladder volume,compliance,detrusor activity and residual urine;parameters used for SEPs evaluation were latent period and amplitude.Results There was a statistics significant difference between operation and control group;the similar result was attented in the comparison of before and after operation,also in the comprison of the improved group and the group without improvement after operation.Conclusions UDS and SEPs investigation can provide guidance for the treatment of tethered cord syndrome(TCS)and evaluate clinical prognosis.These cases with the severity changing in UDS and somatosensory shall be avoided unnecessary action in operation.

OBJECTIVETo establish a rapid quantitative analysis method for the content of chlorogenic acid and solid content in the extraction liquid concentration process during the production of Reduning injection by using the near-infrared (NIR) spectroscopy, in order to reflect the concentration state in a real-time manner and really realize the quality control of concentrating process of the extraction and concentration process.

METHODThe samples during the Jinqing extraction liquid concentration process were collected. After the removal of abnormal samples, the spectra pretreatment and the wave band selection, the quantitative calibration model between NIR spectra and chlorogenic acid HPLC analytical value and solid content was established by using PLS algorithm, and unknown samples were predicted.

RESULTThe correlation coefficients between the chlorogenic acid content and the solid content were respectively 0.992 1 and 0.994 0, and the correlation coefficients of the verification model were respectively 0.994 4 and 0.998 4, with the root mean square error of calibration (RMSEC) of 0.814 6 and 2.656 1 and the root mean square error of prediction (RMSEP) of 0.704 6 and 1.876 7 respectively, and the relative standard errors of predictions (RSEP) were 6.01% and 2.93% respectively.

CONCLUSIONThe method is simple, rapid, nondestructive, accurate and reliable, thus could be adopted for the fast monitoring of the chlorogenic acid content and the solid content during the concentration process of Reduning injection extraction liquid.

OBJECTIVETo observe the therapeutic effect of Xiaozheng Rongmu Powder (XRP) for the treatment of progressive CCl4-induced liver cirrhosis in rats.

METHODSRat liver cirrhosis model was established by subcutaneous injection of 50% CCl4-olive oil 2 mL/kg twice a week for 12 weeks. Experimental rats were divided into the control group treated by saline and the two treatment groups, treated with XRP and Xiaochaihu Decoction, respectively, with the treatment starting from the 9th week of modeling. Rats were sacrificed at the terminal of experiment, the death rate, character of ascites, liver histological changes, liver function, mRNA expression of hepatocyte mitosis and the liver fibrosis associated markers in rats were observed.

RESULTSAt the end of the 8th week of modeling, serum levels of ALT, AST and TBil were increased, and Alb decreased significantly in rats (P < 0.01), cirrhosis formation with ascites could be seen in all rats. Meantime, levels of vascular smooth muscle alpha-actin, transforming growth factor-beta1, collagen I A2, tumor necrosis factor-alpha, tissue inhibitor of melalloproteinase-1 mRNA increased, while matrix melalloproteinase-13 mRNA were decreased significantly (P < 0.01), with visible liver proliferation to some extents. Further changes of above-mentioned abnormalities and clear suppression of hepatocytes mitosis were found in the modeled rats at the end of the 12th week. As compared to those occurred in the control group, changes in the XRP treated group were significantly milder at the corresponding duration, and clearly active hepatocytes mitosis was shown.

CONCLUSIONXRP, a Chinese drug with the effect of dissolving phlegm, removing stasis and supplementing qi, could reverse the progress of cirrhosis formation induced by CCl4, and it brings potential new hope for the treatment of advanced cirrhosis by Chinese medicine.

OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.

METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.

RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.

CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

The complete genomic sequence of Duck hepatitis virus 1 (DHV-1) ZJ-V isolate was sequenced and determined to be 7 691 nucleotides (nt) in length with a 5'-terminal un-translated region (UTR) of 626 nt and a 3'-terminal UTR of 315 nt (not including the poly(A) tail). One large open reading frame (ORF) was found within the genome (nt 627 to 7 373) coding for a polypeptide of 2 249amino acids. Our data also showed that the poly (A) tail of DHV-1 has at least 22 A's. Sequence comparison revealed significant homology (from 91.9% to 95.7%) between the protein sequences of the virus in the Picornaviridae family, its genome showed some unique characteristics. DHV-1 contains 3copies of the 2A gene and only 1 copy of the 3B gene, and its 3'-NCR is longer than those of other picornaviruses. Phylogenetic analysis to do sequence homology based on the VP1 protein sequences showed that the ZJ-V isolate shares high sequence homology with the reported DHV-1 isolates (from 92.9% to 99.2%), indicating that DHV-1 is genetically stable.
