1.Animal experimental study of intra-articular injection of S-methylisothiourea for treatment of temporomandibular joint osteoarthrosis.
West China Journal of Stomatology 2007;25(3):213-215
OBJECTIVETo investigate the efficacy of S-methylisothiourea (SMT) for treatment of temporomandibular joint osteoarthrosis (TMJOA) of goats.
METHODSNine purebred black goats were randomly devided into three groups: Normal control group, control group and experimental group. The upper compartments of both temporomandibular joint of the goats in control group and experimental group were injected with collagenase only once to induce osteoarthrosis. Normal control group received no treatment. The upper compartments of both TMJ were injected with 0.5 mL of normal saline, and experimental group, the upper compartments of both TMJ were injected with 0.5 mL of SMT. The TMJ of goats was examined with scanning electron microscopy and microscopy after sacrificed.
RESULTSExamined in light microscopy and scanning electron microscopy, normal control group showed normal performance, the control group showed severe osteoarthrotic changes in the temporal surface, disk and condyle, while the experimental group showed improvement of different degree.
CONCLUSIONOn the basis of 3-month following-up study, repeated intra-articular injection of SMT may play a role in inhibiting TMJOA progression.

OBJECTIVETo investigate new bone formation of alveolar augmentation with recombinant human bone morphogenetic protein-7 (rhBMP-7) expressed in prokaryocyte.
METHODSTo create the model of rabbit extraction socket into which the composites of rhBMP-7 and the gelatin sponge was immediately implanted, then the samples were investigated 2, 4, 8 and 12 weeks postoperatively by gross observation, scanning electron microscope (SEM), quantitative measurement of calcium content and alkaline phosphatase (ALP) activity.
RESULTSThere was significant difference in height of alveolar ridge absorpted between the experimental groups and the carrier control groups through gross observation. The result of SEM showed that bone healing in rhBMP-7 groups was 4-6 weeks earlier than that of control groups. ALP activity in rhBMP-7 groups were obviously high compared with that of control groups.
CONCLUSIONThe BMP-7 has a satisfactory osteoinduction ability to promote new bone formation and prevent alveolar bone absorption.

BACKGROUNDColon cancer is a common malignant tumor in the clinic with an incidence rate that is increasing in recent years. The key point for improving the survival rate is the diagnosis and treatment at an early stage. The purpose of this study was to compare the difference of the Fuji Intelligent Chromo Endoscopy (FICE) and staining technique for the diagnosis of colon tumors and non-tumor lesions.
METHODSFrom March to November 2007, 654 patients were examined with ordinary colonoscopy. Among them 223 patients with colon neoplasm or polypoid lesion were included. The patients were examined with a magnifying ordinary colonoscopy, a magnifying FICE technique and magnifying staining technique. The pit pattern and blood capillary form of the lesion were examined, an endoscopic diagnosis was made and it was compared with the pathologic diagnosis.
RESULTSFour hundred and fifty-one neoplasms were detected in the 223 patients, among those 91.1% (411/451) were detected with the magnifying ordinary endoscopy while 99.1% (447/451) were detected with the FICE technique; there was a significant difference between the two methods. FICE could clearly show the structure and form of mucosal blood capillaries (P < 0.01) but there was no significant difference between the two methods for showing the pit pattern. The coincident rate of FICE for the diagnosis of tumor and non-tumor lesions was 91.6% (413/451), that of the magnifying staining technique was 82.0% (370/451) (P < 0.05).
CONCLUSIONSMagnifying FICE could show the mucosal microstructure and blood capillary form and it had a superiority of high coincident rate, high sensitivity and specificity when compared with ordinary magnifying colonoscopy and magnifying staining endoscopy. In addition, it was easy to operate and a biopsy could be taken from the target, so it has a satisfactory clinical practical value.

Objective:
To compare the clinical efficacy and safety of bortezomib, cyclophosphamide, dexamethasone (VCD) regimen and bortezomib dexamethasone (VD) regimen in the treatment of the patients with newly diagnosed multiple myeloma (NDMM).
Methods:
The clinical data of 73 patients with NDMM in Shanxi Dayi Hospital from January 2013 to January 2016 were retrospectively analyzed. According to the chemotherapy regimen, the patients were divided into VCD group (41 cases) and VD group (32 cases). The efficacy and adverse reactions of the two groups were evaluated.
Results:
The overall response rate of VCD group and VD group was 80.5% (33/41) and 78.1% (25/32) respectively, and the difference was not statistically significant (

OBJECTIVETo discuss the clinicopathological factors for lymph node metastasis (LNM) in early gastric cancer (EGC), including age, gender, location, size, macroscopic type, depth of invasion, histological type, and lymphatic invasion, and the regulation of LNM in EGC.
DATA SOURCESThe data used in this review were mainly from PubMed articles published in English. The search terms were "early gastric cancer" and "lymph node metastasis".
STUDY SELECTIONArticles were selected if they reported the clinicopathological factors and regulation of LNM in EGC.
RESULTSThe prognosis of EGC is better than advanced gastric cancer, with over 90% 5-year survival rate. The main risk factors for LNM in EGC are tumor size, macroscopic type, depth of invasion, histological type, ulceration, and lymphatic invasion.
CONCLUSIONSLNM in EGC is a critical factor for assessment of prognosis and determination of therapeutic strategy. Endoscopic mucosal resection or endoscopic submucosal dissection should be considered when patients have low risk of LNM.
