ABSTRACT

The complexity of oral ulcerations poses considerable diagnostic and therapeutic challenges to oral specialists. The expert consensus was conducted to summarize the diagnostic work-up for difficult and complicated oral ulcers, based on factors such as detailed clinical medical history inquiry, histopathological examination, and ulceration-related systemic diseases screening. Not only it can provide a standardized procedure of oral ulceration, but also it can improve the diagnostic efficiency, in order to avoid misdiagnosis and missed diagnosis.

ABSTRACT

Hypertension is a prevalent systemic disease in the elderly, who can suffer from several pathological skeletal conditions simultaneously, including osteoporosis. Benidipine (BD), which is widely used to treat hypertension, has been proved to have a beneficial effect on bone metabolism. In order to confirm the osteogenic effects of BD, we investigated its osteogenic function using mouse MC3T3-E1 preosteoblast cells in vitro. The proliferative ability of MC3T3-E1 cells was significantly associated with the concentration of BD, as measured by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay and cell cycle assay. With BD treatment, the osteogenic differentiation and maturation of MC3T3-E1 cells were increased, as established by the alkaline phosphatase (ALP) activity test, matrix mineralized nodules formation, osteogenic genetic test, and protein expression analyses. Moreover, our data showed that the BMP2/Smad pathway could be the partial mechanism for the promotion of osteogenesis by BD, while BD might suppress the possible function of osteoclasts through the OPG/RANKL/RANK (receptor activator of nuclear factor-κB (NF-κB)) pathway. The hypothesis that BD bears a considerable potential in further research on its dual therapeutic effect on hypertensive patients with poor skeletal conditions was proved within the limitations of the present study.

ABSTRACT

Objective To evaluate the efficacy of microsurgical techniques combined with bone transportation for osteomyelitis following open fracture on the leg.Methods From April 2007 to April 2016,25 patients with osteomyelitis caused by severe open injury on the leg were treated at Orthopaedic Department,General Hospital of Rocket Force.They were 22 men and 3 women,aged from 19 to 65 years (average,36.5 years).Their open injury was located at upper tibia in 6 cases,at middle tibia in 6 and at lower tibia in 13.Eight patients received internal fixation with plate and 17 unilateral external fixation.By the Cierny-Mader classification,their chronic osteomyelitis was of type Ⅲ in 14 cases and of type Ⅳ in 11.The tibial defects after excision of infectious segment ranged fromn 5 to 14 cm in length (average,8.8 cm).After infectious tissues were removed,antibiotic bone cement chains were inserted into the defects.The open wounds were covered with microsurgical pedicled or free flaps.Bone transportation with unilateral external fixation was used to deal with the bone defects after removal of the infectious bone.Results Bone infection was controlled in the 25 patients.The rate of infection control after one debridement procedure was 76.0% (19/25),and that after 2 debridement procedures was 24.0% (6/25).Flap repair led to early closure of the open wounds.The successful rate of wound closure after one operative procedure was 84.0% (21/25),and that after secondary operation was 16.0% (6/25).Bony union of tibial defects was achieved in all the 25 patients with no recurrence of osteomyelitis.The patients were followed up for 18 to 36 months (average,24.6 months).Re-fracture happened in one case and was treated with another operation.Bone union time starting from bone transportation ranged from 8 to 18 months (average,10.5 months).Time for external fixation ranged from 12 to 20 months (average,18.4 months).Conclusion For osteomyelitis caused by severe open injury on the leg,microsurgical techniques can be used to repair open wounds and bone transportation to reconstruct bone defects after removal of infectious bone.

ABSTRACT

Objective To report the clinical outcomes of latissimus dorsus flap used to reconstruct severe trauma on lower leg.Methods From May 2011 to September 2016,12 patients were treated for severe trauma on lower leg at Orthopaedic Department,General Hospital of Rocket Force.They were 10 men and 2 women,aged from 22 to 54 years (average,37.5 years).According to the Gustilo classification,their open fractures were of type ⅢA in 2 cases and of type ⅢB in 10.The areas of soft tissue defect ranged from 15 cm × 8 cm to 35 cm × 12 cm.Their wounds were covered with latissimus dorsus flaps;the dorsal expansion of the ankle joint was reconstructed after their bone infection was controlled.Two flaps were anastomosed directly to the anterior tibial vessels and one flap to the femoral vessels.The other 9 flaps were anatomosed to the lateral circumflex femoral artery,bridging with the greater saphenous vein (average length:32 cm).Ten flaps were neuroanatomosed with the motor branch of common peroneal nerve and 2 with the motor branch of vastus lateralis.The therapeutic outcomes were evaluated in terms of repair of soft tissue defects,control of infection and range of active dorsal flexion of the ankle at neutral position.Results The 12 patients were followed up for an average of 3.5 years (from 1 to 6 years).All the 12 flaps survived and infections were eradicated.The fractures were healed with muscle strength of grade 3 to grade 4.Their ankle extension was reconstructed.Their limbs were preserved with satisfactory limb function.The bone exposures of 5 cm × 3 cm and 6 cm × 3 cm in area after debridement respectively in 2 cases of Gustilo type ⅢA were covered with latissimus dorsus flaps.The range of active dorsal flexion of the ankle at neutral position increased from preoperative 10.5° to postoperative 19.1° on average.Conclusion In treatment of severe trauma on lower leg,latissimus dorsus flaps can be used to repair skin wound,control infection and reconstruct ankle function simultaneously,with advantages of reduced operative procedures,a high rate of limb preservation,and better function recovery.

ABSTRACT

Objective To explore and study the nursing care to non-small cell lung cancer (NSCLC) patients by using small dose chemotherapy combined with Aidi injection. Method About 40 NSCLC patients treated with small dose chemotherapy combined with Aidi injection for 1 course about 6 wereks were nursed. Result The curative rate was 37.5%, patients in stable condiction was 90.0%. Conclusions The combination of small dose chemotherapy and Aidi injection are effective in the treatment of the NSCLC patients. Good nursing puncturce and blood, well observation of adverse effect of chemotherapy and medlicine can improve symptom and living quality of patients.

ABSTRACT

Root canal biofilm is frequently detected in the canal wall of infected root canal and the root canal with failed root canal therapy. Due to its special structure and diverse composition, root canal biofilm has the ability of the drug tolerance and antiimmunity, which lead to apical periodontitis. This review summarizes the features of the root canal biofilm and latest clinical methods to remove it.

ABSTRACT

<p><b>OBJECTIVE</b>To introduce the applied anatomy of pedicled buccal fat pad (BFP) graft and a series of histological changes in the healing process of BFP as an uncovered pedicled graft.</p><p><b>METHODS</b>The healing processes of BFP are demonstrated via uncovered pedicled grafts on rabbits in histological examination. Uncovered buccal fat pads were used to repair soft tissue defects in rabbit oral cavities.</p><p><b>RESULTS</b>The uncovered buccal fat pads showed complete epithelialization of their oral surfaces at 6 to 8 weeks after surgery and were slowly replaced by fibrous tissue.</p><p><b>CONCLUSIONS</b>Advantages of the pedicled buccal fat pad graft include an anatomic region that is consistent and easy to excise. The operation can be performed in one incision, affecting neither appearance nor function of the area. Use of the buccal fat pad provides a good reconstruction of soft tissue defects in the mouth.</p>
