OBJECTIVETo explore relationship between volume of bone cement injection and concurrent of fracture after thoracolumbar osteoporotic vertebral fracture treated by percutaneous kyphoplasty (PKP).

METHODSFrom January 2006 to December 2008,68 patients with thoracolumbar osteoporotic vertebral fracture treated by PKP were retrospectively analyzed. Among them, 30 patients with less than 3 ml bone cement injection (mean 2.5 ml, low group), including 11 males and 19 females, with an average age of (85.0 +/- 8.5) years (ranging for 60 to 91); 38 cases with over 4 ml bone cement injection (mean 4.5 ml, large group), including 15 males and 23 females,with an average age of (86.0 +/- 9.2) years (ranging for 60 to 93). Factors of concurrent vertebral fractures were observed during follow-up.

RESULTSAll patients were followed up from 3.4 to 5.1 years with an average of 3.8 years. Thirteen patients (43.3%) co-occurred fracture in low group,among which strengthened concurrent vertebral fracture occurred in 1 case,upper and lower section adjacent vertebral fracture in 8 cases,distal segment of vertebral fracture in 4 cases; while 18 patients (47.3%) co-occurred fracture in large group,among which strengthened concurrent vertebral fracture occurred in 2 cases, upper and lower section adjacent vertebral fracture in 10 cases,distal segment of vertebral fracture in 6 cases. No significant difference between two groups (P > 0.05).

CONCLUSIONBone cement injection is not main influence factors for treating concurrent of fracture after thoracolumbar osteoporotic vertebral fracture by PKP. Concurrent fracture mainly relates with progress of osteoporosis, the volume of injection volume may appropriately over the volume of balloon.

OBJECTIVETo explore the immunological pathogenesis of multiple sclerosis (MS) patients of different TCM syndrome types.

METHODSFifty-nine MS patients were assigned to two types by syndrome typing according to their clinical manifestations, the Gan-Shen yin-deficiency (GSYD, 40 cases) type and the both yin-yang deficiency (YYD, 19 cases) type. Difference of patients' age of first attack, times of relapsing, duration of disease, MRI finding and evoked potential between the two groups were compared. The immunology indexes were also compared in part of the patients (26 cases in GSYD type and 12 cases in YYD type).

RESULTSThe age of first attack was later (P < 0.01), level of myelin basic protein in cerebrospinal fluid was higher (P < 0.05), in the YYD type than those in the GSYD type. Besides, the relapsing time in GSYD type, and the blood-brain barrier index and level of myelin basic protein in YYD type showed an ascending trend (P = 0.056, 0.074, 0.093, respectively).

CONCLUSIONImmunological difference exists between the MS patients of GSYD type and those of YYD type.

Negative-pressure wound therapy (NPWT) has been used to help wound healing since early 1970s, and it has been used increasingly for treating a wide variety of wounds since the early 1990s and started to popularize in China near the mid 1990s. This technique is different from conventional dressing change, as it controls local humidity, alleviates edema, and improves local circulation all by negative pressure. The method generally involves the application of a dressing on the wound surface, connecting the dressing to a vacuum pump through a tube, and then sealing the wound with adhesive films. Most of the clinicians in China believe that NPWT is helpful in accelerating wound healing, though as yet there is no strong evidence to support it. Therefore, it is necessary to conduct more research to further clarify the mechanism and therapeutic effect of NPWT.

BACKGROUND:Cervical cancer is one of the most frequent malignancies in women worldwide, and its occurrence and development is closely related to cyclooxygenase-2 (COX-2).OBJECTIVE: To examine the expression of COX-2 alternative splicing variants in human cervical carcinoma tissue and understand its possible implications.DESIGN: Non-randomized controlled experiment.SETTING: Key Laboratory of Biochemistry and Molecular Pharmacology,Department of Obstetrics and Gynecology, First Affiliated Hospital,Chongqing Medical University.PARTICIPANTS: Carcinoma tissue and normal tissue were obtained from 13 cervical carcinoma patients admitted during March 2002 to April 2002in the Department of Obstetrics and Gynecology, First Affiliated Hospital,Chongqing Medical University.METHODS: A pair of specific primers were designed for reverse transcription-polymerase chain reaction (RT-PCR) to obtain the mRNA of COX-2 in human cervical carcinoma tissues. The resultant band on electrophoresis was cloned, sequenced and analyzed.MAIN OUTCOME MEASURES: ① Agarose gel electrophoresis result of the PCR product of carcinoma and normal tissues; ② Sequencing result of the electrophoresis band from carcinoma and normal tissues.RESULTS: No COX-2 band (252 bp) was found in electrophoresis for normal tissues, while 2 bands appeared for cervical carcinoma tissues, including a new electrophoresis band of 534bp besides the COX-2 band. Cloning and sequencing revealed that this new band contained not only exons 7and 8 of COX-2 gene but also a reserved intron of 282 bp intron between exons 7 and 8. Analysis of the predicted amino acid sequence indicated that an in-frame stop codon occurred in the 48-50 bp of the intron retained in the mRNA.CONCLUSION: The presence of COX-2 alternative splicing mRNA variant (Genbank accession number:BU493602)is confirmed in human cervical carcinoma tissue, which codes for a protein possibly smaller than COX-2.
