Objective To investigate urinary tract injuries in laparoscopic-assisted vaginal hysterectomy(LAVH).Methods Clinical data of 5 cases of urinary tract injuries from 415 cases of LAVH from December 1995 to January 2006 in this hospital were retrospectively studied. Results Intraoperative bladder injury occurred in 2 cases and an immediate repair was given.Postoperative ureteral injury occurred in 3 cases: 2 cases of ureteral injury were found 4 days after operation because of abdominal pain,and 1 case was found on the 30th day after operation because of massive vaginal discharge.Conclusions Urinary tract injury is one of common complications in laparoscopic-assisted vaginal hysterectomy.High-risk factors include tumor size more than 5 cm,tumor protruding to the broad ligament,and tumor adjacent to the isthmus.Surgical repair is the major treatment.

Background Stickler syndrome is a genetic connective tissue disorder that affects the ocular,skeletal,orofacial and auditory systems.To determine the gene mutation loci can offer a basis for genetic diagnosis and management of Stickler syndrome.Objective The aim of this study was to research the clinical characteristics of a pedigree with Stickler syndrome and identify the disease-causing gene mutation.Methods This study was approved by Ethic Committee of Peking Union Medical College Hospital.The clinical study and pedigree analysis were performed in one family with Stickler syndrome type Ⅰ (STL Ⅰ).Nine family members were examined with informed consent.The entire coding regions of COL2A1 gene with flanking intronic regions were amplified by PCR and directly sequenced.The detected sequence change was confirmed to be mutationloci by examining whether they existed in normal control individuals.Mutant proteins were predicted with online software.Results There were 4 generations and 11 members in this family,and 2 members died,including 1 patient.Three patients were found in 9living families.Inheritance of this family complicd with an autosomal dominant inheritance mode.All affected individuals showed the consistent phenotypes with STL Ⅰ,including high myopia,membranous vitreous anomaly and surface central flat,short nose,palatoschisis,etc.Mutation screening of COL2A1 gene revealed that the first base of intron 12 was deleted(IVS12+1G del).Nucleotide sequence analysis showed that this mutation led to the functional abnormal of this gene by forming termination cordon in advance.This mutation occurred in all affected individuals,however,no mutation was observed in any unaffected member or 100 normal unrelated individuals.Conclusions This study identifies a novel splice-site mutation(IVS12+ 1G del)in COL2A1 gene in a Chinese STL Ⅰ pedigree.This is the first report on a mutation in a Chinese STL Ⅰ family.

OBJECTIVETo study the anti-immune inflammation efficacy and toxicity of Tripterygium wilfordii decoction, in order to provide experimental basis for studies on its "efficacy-toxicity" correlation.
METHODThe delayed hypersensitivity model was established by dinitrofluorobenzene in mice. Different doses of T. wilfordii decoction was administered for 5 consecutive days. The ear swelling inhibition ratio and the toxic action were observed. After the final administration, the biochemical indexes of PGE2, TNF-α, IL-2, ALT, AST, PA, TBA, TBIL in serum were detected, and the visceral indexes of heart, liver, spleen and kidney were measured.
RESULTThe DNFB-induced ear swelling could be notably inhibited by multiple oral administration of T. wilfordii decoction, with the ED50 and its 95% confidence limit of 0.34 (0.21-0.42) g x kg(-1). The contents of PGE2, TNF-α, IL-2 in serum decreased in a dose-dependent manner. The activities of serum AST, ALT, TBA, TBIL and the PA content reduced.
CONCLUSIONT. wilfordii decoction shows a significant anti-immune inflammation efficacy within the dosage range between 0.59 and 2.34 g x kg(-1) in a dose-dependent manner. With a certain hepatotoxicity, high dose (2.34-4.68 g x kg(-1)) of T. wilfordii decoction can cause substantial liver injury, with a dose dependence in liver function index. Therefore, the efficacy and toxicity of T. wilfordii is dose dependent, which provides reference for preventing adverse drug reactions in clinic and developing early-warning schemes and ensure the clinical medication safety of T. wilfordii.

Objective: To investigate the effects of a Chinese herbal formula for calming liver and suppressing yang on the protein expressions of vascular tissues in spontaneously hypertensive rats (SHRs), and to explore the mechanism of efficacy. Methods: Twenty SHRs were randomly divided into model group and treatment group. Another 10 Wistar-Kyoto rats were selected as a normal control. SHRs in the treatment group were administered with the formula for calming liver and suppressing Yang for 4 weeks. During the course of treatment, blood pressure and heart rates were monitored every week and the ethology of rats, including irritability and rotation endurance was also evaluated. After treatment, thoracic aorta was obtained and its proteins were separated by 2-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and database query. Results: The formula for calming liver and suppressing yang not only decreased the systolic blood pressure and heart rate, but also improved irritability degree and rotation endurance time of SHRs. This experiment had established the 2-DE graph of protein expressions of vascular tissues in SHRs. Compared with the normal group, the expressions of 15 proteins were down-regulated, and 12 proteins were up-regulated in vascular tissues of the model group. The formula for calming liver and suppressing yang treatment up-regulated expressions of 10 proteins in the 15 down-regulated proteins, and down-regulated 8 proteins in the 12 up-regulated proteins in vascular tissues of SHRs. After analysis, 16 obviously differentially expressed proteins were found, and 13 of them were identified. Conclusion: The formula for calming liver and suppressing yang can improve the ethology of SHRs. The mechanism is probably concerned with regulating the protein expressions of vascular tissues.

Objective To detect the mRNA expression of KPNA2 in hepatocellular carcinoma(HCC) tissue and to investigate its relationship with the clinicopathological features of HCC so as to provide the basis for predicting HCC infiltration ,metastasis and early treatment .Methods The HCC tissue and paracarcinoma normal tissue from 30 operative cases of HCC in the hepatobiliary surgery department of this hospital from January 2011 to November 2013 were collected and detected KPNA2 expression at the transcriptional level by RT-PCR .The correlation between the mRNA expression of KPNA2 with the clinicopathological factors of HCC was analyzed by consulting the medical record data .Results Among 30 cases of HCC ,the ratio of KPNA2 mRNA in the HCC tissue and the paracarcinoma normal tissue in 25 cases(83 .33% ) was up-regulated (grey value >2 times) .Therefore ,the KP-NA2 gene exhibited the high expression in the HCC tissue and low expression in the paracarcinoma normal tissue .Conclusion KP-NA2 is highly expressed in the HCC tissue and lowly expressed in the paracarcinoma normal tissue ;the high expression of KPNA2 is positively correlated with the stage and pathological grading of HCC ;KPNA2 may be used as an important indicator for early di-agnosing HCC and judging the malignant degree and potential metastais ability of HCC .

OBJECTIVE: To study the effects of Wenyang Chubi Decoction (WYCBD), a compound traditional Chinese herbal medicine, on connective tissue growth factor (CTGF) and collagen-I (COL-I) in a mouse model of scleroderma. METHODS: Scleroderma was induced in BALB/c mice by daily local injection of bleomycin for three weeks and the mice were randomly divided into untreated, WYCBD-treated and normal saline (NS) treated groups, with another group of BALB/c mice as normal control. WYCBD and NS were given orally for one month respectively. Histopathology in the skin and lungs of the mice were examined. The CTGF and COL-I expressions in the skin or skin lesions were detected by immunohistochemical Elivision assay. RESULTS: The expression levels of CTGF and COL-I in the untreated group were significantly higher than those in the normal control group (P<0.05). Compared with the NS-treated group, the WYCBD-treated group had significant improvement in the skin and lung histopathology and remarkably decreased expression levels of CTGF and COL-I (P<0.05). CONCLUSION: Scleroderma mice showed high expressions of CTGF and COL-I in the skin. WYCBD had the effects of decreasing the CTGF and COL-I expressions and improving the skin fibrosis.
