OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

BACKGROUND:Nano-size inorganic filling greatly improves mechanic characteristic of composite resin.However,its effects on pulp tissue remain unclear.OBJECTIVE:To evaluate the biocompatibility of FiltekTM Z350 nano-composite resin on dog pulp tissue by means of histology observation.DESIGN,TIME AND SETTING:Randomized control animal experiment was performed at the animal experiment center of Fuzhou General Hospital,Nanjing Military Area Command of Chinese PLA from April 2007 to April 2008.MATERIALS:Sixty healthy teeth from three adult male beagle dogs were recruited in this study.METHODS:Buccal Class V deep cavities were prepared in beagle dogs,which were then divided into four groups at random.FiltekTM Z350 resin,Dyract AP compomer and TPH resin were used to restore the cavities in three testing groups and glass ionomer cement was used as control.All cavities were treated with Clearfil SE BOND before filling.Intact healthy teeth were used as blank control.MAIN OUTCOME MEASURES:The pulp condition of each tooth was studied histologically.The remaining dentine thickness of each cavity was measured.RESULTS:After 7 days,mild inflammatory response was observed in most of the specimens.After 30 and 90 days,normal histological characteristics were observed in almost all specimens except TPH resin group.The histological structure disturbance of dentin cell layer emerged in some specimens of TPH group,which was higher than other testing groups(P 0.05).CONCLUSION:FiltekTM Z350 nano-composite resin has similar biocompatibility as Dyract AP compomer and glass ionomer cement,better than TPH resin.

OBJECTIVETo observe the effect of tensile stress on human heel skin fibroblast proliferation in vitro, providing a theoretical basis for preventing the wound edge skin necrosis and nonunion after calcaneal fracture surgery.

METHODSFibroblast cells were taken from lateral heel skin of a 40 year-old-man, then cultured and subcultured in vitro. After that, they were divided into three groups: 0 hours group, 6 hours group and 24 hours group and were tested by tensile stress testing. The levels of TGF-β1 and IL-6 in nutrient fluid were measured. Transmission electron microscope and light microscope was applied for observe mitochondria and nucleus.

RESULTSUnder 10% of the tensile stress, mitochondria decreased, the levels of TGF-β1 and IL-6 in nutrient fluid were decreased and cell proliferation was inhibited gradually with time increasing.

CONCLUSIONThe human lateral heel skin in a long-time tensile stress state is an important cause of wound edge skin necrosis and nonunion after calcaneus fracture surgery.

Objective To investigate the incidence of gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN) in Chengdu City in 2010 and summarize clinical characteristics of GEP-NEN.Methods The incidence of GEP-NEN was estimated with the data in 2010 from the databases of West China Hospital and Chengdu Health Information Centre.Results A total of 77 cases of GEP-NEN were diagnosed in West China Hospital in 2010.Ten cases from other hospitals or non-Chengdu citizenship were excluded,so a total of 67 cases were included in this study.In 2010,the incidence of GEP-NEN was 1.86/105 in Chengdu City.Among 67 GEP-NEN cases,most lesions were located in pancreas and rectum (38 cases,56.7％),followed by stomach (10 cases),esophagus (seven cases) and duodenum (four cases).Among 57 GEP-NEN cases which had pathotogial grading,26 cases (45.6 ％) had neuroendocrine carcinomas or mixed adenoneuroendocrine carcinomas when diagnosed.Conclusions In 2010,the incidence of GEP-NEN in Chengdu City is similar to the reports from other countries.Pancreas,rectum and upper gastrointestinal tract are predilection sites of GEP-NEN.The diagnosis rate of early GEP NEN needs to be raised.

Objective To study the accuracy and the clinical significance of sentinel lymph node biopsy (SLNB)after neoadjuvant chemotherapy for breast cancer.Methods A total of 90 patients with StageⅡorⅢbreast cancer and negative axillary node after neoadjuvant chemotherapy were enrolled in the study.Mapping proce- dure and SLNB were performed using methylene blue injected at the site of the primary breast cancer,followed by the axillary lymph node dissection.Results The sentinel lymph node(SLN)was successfully identified in 82 out of 90 patients(91.1%).The number of sentinel harvested nodes ranged from 1 to 4(average 1.6).The accuracy of SLNB to predict the axillary lymph node status was 93.9 %(77/82),the sensitivity,positive predictive value,nega- tive predictive value and false negative rate were 87.5 %(40/45),100 %,88.1% and 11.1%(5/45),respectively. The SLN identification rate tended to be higher and false negative rate tended to be lower in patients with T2 prima- ry tumor before neoadjuvant chemotherapy.Conclusion Our study indicated that SLNB after neoadjuvant chemotherapy in patients with StageⅡorⅢbreast cancer had a similar effect as SLNB in non-neoadjuvant studies. SLNB was considered to be able to accurately predict the axillary lymph node status in patients with T2 primary tu- mor before neoadjuvant chemotherapy.

AIM:To investigate the role of microRNA-486-5p (miR-486-5p) in the apoptosis of human bone marrow mesenchymal stem cells (hMSCs) induced by hydrogen peroxide (H2O2).METHODS: The hMSCs were cul-tured in vitro and exposed to serum-free medium and H2O2(10 mmol/L).The changes of miR-486-5p expression in oxida-tive stress-related apoptosis of hMSCs were measured by real-time PCR.The hMSCs were transfected with miR-486-5p mimic or inhibitor at concentration of 30 nmol/L by Lipofectamine RNAiMAX.The effect of miR-486-5p on H2 O2-induced decrease in cell viability was evaluated by MTT assay.Hoechst 33342 staining and flow cytometry were applied to determine the role of miR-486-5p in the apoptosis of hMSCs.The protein expression was evaluated by Western blotting.Caspase-3 ac-tivity was determined using a caspase-3 activity kit.RESULTS:Compared with control group, the expression of miR-486-5p significantly decreased after treated with H2O2(P<0.05).In addition, over-expression of miR-486-5p in the hMSCs reduced the cell viability, accelerated apoptosis, down-regulated Bcl-2/Bax ratio, caspase-3 enzyme precursor content and phosphorylation of Akt, and activated caspase-3 activity.Conversely, down-regulation of miR-486-5p significantly inhibited H2 O2-induced cell apoptosis and the caspase-3 activity, increased cell viability and up-regulated Bcl-2/Bax ratio and phos-phorylation level of Akt.CONCLUSION:Over-expression of miR-486-5p promotes H2 O2-induced hMSCs apoptosis, and repression of miR-486-5p protects hMSCs from H2 O2-induced cellular apoptosis, which may be mediated by regulating Akt signaling pathway.
