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.

During the latest researches on knee ostarthritis,it is discovered that before the morphology changes of cartilage,there were changes of the content of proteoglycan and water and changes of alinement of surface layer collagen fibers in cartilage matrix.By the new technologies of DWI,proton density mapping image,23Na MRI,T2Mapping image and so on,not only the pathological changes of cartilage can be disclosed,the component changes of cartilage matrix can also be detected.Accompany with the progress in the technology of software and hardware,MRI will have more and more prospects in early diagnosis and therapeutic effect evaluation of knee ostarthritis.

Objective To compare the differences between external standard method and relative correction factor method for determination of the flavonoids from Sorbus tianschanica Rupr.Methods Using HPLC external standard method for determination of hyperoside,rutin,isoquercitrin,quercetin-3-O-(6″-O-malonyl)-β-D-glucoside,astragalin and Kaempferol-3-O-(6″-O-malonyl)-β-D-glucopyranoside in Sorbus tianschanica Rupr.,HPLC relative correction factor method was adopted to establish relative correction factor of the other five flavonoids above with hyperoside as reference.The difference was evaluated by comparing the external standard method with the relative correction factor method.Results There was no significant difference between the T test external standard method and relative correction factor method(P>0.05).Conclusion External standard method and relative correction factor method can be used for determination of the flavonoids from Sorbus tianschanica Rupr.,but in the case of lack of reference substance or mass detection,using the relative correction factor method for determination of rutin,hyperoside isoquercitrin,quercetin-3-O-(6″-O-malonyl)-β-D-glucoside,astragalin and kaempferol-3-O-(6″-O-malonyl)-β-D-glucopyranoside in Sorbus tianschanica Rupr.It was more feasible and it can be used as a new quality evaluation method in determination of flavonoid components from Sorbus tianschanica Rupr.

Objective To investigate the effects of low molecular heparin(LWMH)on cytokines(TNF-?,IL-1? and IL-10)in blood plasma and bronchoalveolar lavage fluid of invasive pulmonary aspergillosis(IPA)mice.Methods The neutropenic IPA mouse models were established by administration of cyclophosphamide for immunologic function inhibition and intranasally challenge with Aspergillus fumigatus conidia(1?106 conidia/mouse).One hundred and twenty mice were randomly divided into 4 groups:normal control,IPA model,normal saline+LWMH and IPA+LWMH group.Normal saline+LWMH group and IPA+LWMH group received LWMH(subcutaneous injection,1 000 IU/kg,qd?2 d).Normal control and IPA model group received normal saline instedad of LWMH.At 4,8,12,24 and 48 h after inoculation,six mice were randomly taken from each group to be sacrificed.ELISA method was used to determine the concentrations of TNF-?,IL-1? and IL-10 in blood plasma and BALF.Results TNF-?,IL-1? and IL-10 in blood plasma and BALF increased significantly several hours after inoculation of conidia in IPA model and IPA+LWMH group.There were significant higher concentrations of TNF-? and IL-1? in blood plasma and BALF in IPA+LWMH group than in IPA model group(P

AIM:To study the KIF21A gene mutation in a Han family with concomitant exotropia. ·METHODS: The genomic DNA of five family members was extracted from peripheral blood leukocytes and amplified with PCR. The PCR products were purified for DNA sequencing. DNA sequences were aligned with the human KIF21A gene sequences registered in GenBank. · RESULTS: Mutation analysis of all exons of the pedigree's KIF21A gene reveals no gene mutation in any of the families. ·CONCLUSION: Our study demonstrates that the KIF21A gene maybe is not virulence gene in this pedigree.
