Objective To observe the clinical efficacy of fire-needle therapy plus oral administration ofGuizhi Fuling capsules in treating ovarian cysts.Method Seventy-six patients with ovarian cysts were randomized into a treatment group and a control group, 38 cases each. The treatment group was intervened by fire-needle therapy plus oral administration ofGuizhi Fuling capsules, while the control group was intervened by oral administration ofGuizhi Fuling capsules alone. Before and after the treatment, ultrasound B-scanning was adopted to measure the sizes of ovarian cysts, and the therapeutic efficacies were compared between the two groups.Result The sizes of ovarian cysts were significantly changed after the treatment in both groups (P<0.01). The sizes of ovarian cysts in the treatment group were significantly different from those in the control group after the intervention (P<0.05). The total effective rate was 86.8% in the treatment group versus 65.8% in the control group, and the between-group difference was statistically significant (P<0.05).Conclusion Fire acupuncture plus oral administration ofGuizhi Fuling capsules is an effective approach in treating ovarian cysts.

[Objective]To observe the expressional variability and correlation of cox-2 and p53 protein between osteosarcoma and osteochondroma and explore their clinical significance.[Method]Sixty Specimens divided into 2 groups were taken from the department of pathology,Third Hospital of Hebei Medical University during 1998~2004.Among them,40(24 male and 16 female)aged 8~38(18.68?6.47)at time of therapy were from cases of osteosarcoma excision;20(13 male and 7 female)aged 9~27(17.95?4.77)from benign lesion of bone(osteochondroma)operation.Immunohistochemistry staining(Streptavidin-Peroxidasc,S-P method)was performed to detect the expressions of cox-2 protein and p53 protein in 40 cases of osteosarcoma.The criteria of positive expression was that brown granule was found in cytoplasm(cox-2)or in nucleus(p53).The percentage of cox-2 or p53 positive expression in five high power fields was cunted randomly in each case.Positive(-):positive oncocytes account 50%.Software SAS v6.12 was used in data analysis.The difference of cox-2 and p53 expressions between osteosarcoma and osteochondroma was analyzed with Chi-square Test.Spearman method was used,with the standard ?=0.05,to analyze the relationship between cox-2 and p53 expression among osteosarcoma.[Result]The positive rate of cox-2 and p53 expressions were 67.5% and 55.0% in osteosarcoma,there was noticeable distinction between osteosarcoma and osteochondroma,most of them was high.There was a positive correlation between them,rs=0.58,P

BACKGROUND: The aseptic loosening of prosthesis has become one of the most obvious matters after operation of prosthesis replacement. OBJECTIVE: To verify the effect of ibandronate on early fixation of implants by local application. METHODS: Forty-four Zelanian rabbits were used in the experiment. A standard animal model of the rabbits' both tibia was embedded with metal screw into the proximal end. Ibandronate at 1 mg/L was sprinkled locally in the left tibia of every rabbit (experimental group), while saline solution was given in the right tibia (control group). (P < 0.001). These findings indicate that, local application of ibandronate solution can obviously promote new bone formation at the earlier period, improve early fixation of implants and decrease the incidence of aseptic loosening of prosthesis.

BACKGROUND:Currently, modified laminoplasty with C7 spinous process and muscle attachment points reserved and C2, C7 decompressive laminectomy can reconcile both ful decompression and structure stability. With early isometric neck muscle exercise, it can enhance cervical dynamic and static force balance and maintain the stability of the cervical spine.
OBJECTIVE:To investigate the clinical effects of modified cervical laminoplasty with postoperative isometric neck muscle exercise on cervical spondylotic myelopathy patients.
METHODS:114 patients with cervical myelopathy were separately performed traditional cervical laminoplasty (control group), modified cervical laminoplasty (modified group), modified cervical laminoplasty, and neck muscle isometric exercise (combined group). Fol ow-up was conducted for 24 months.
RESULTS AND CONCLUSION:(1) Cervical Japanese Orthopaedic Association score, cervical Neck Disabilitv Index scores and the incidence of axial symptoms:There was no significant difference in the Japanese Orthopaedic Association score of three groups at 6, 12 and 24 months after surgery. At 6, 12 and 24 months after surgery, Neck Disability Index scores and constituent ratio of axial symptoms were better in the modified group than the other groups (P<0.05). (2) Results show that modified cervical laminoplasty with isometric neck muscle exercise can get better clinical results in the treatment of cervical myelopathy.

Objective To compare and evaluate the defect-repaired capabilities of human bone morphogenetic protein-2(hBMP-2) gene modified tissue engineered bone in the segmental bone defect model of rabbit's radius.Methods Rabbit's bone mesenchymal stem cells (BMSCs)were transferred with hBMP-2 gene through Adeno-XTM adenoviral expression systems,then seeded onto the compound scaffold of calcium phosphate cemept(CPC)and fibrin glue(FG)to construct a new kind of gene modified tissue engineered bone after proliferation in vitro for three weeks(Group A).Meanwhile,the compound scaffold of calcium phosphate cement(CPC)and fibrin glue(FG),which were seeded by rabbit's bone knesenchyrmal stem cells(BMSCs) after proliferation in vitro for three weeks(group B)and the compound scaffold without cells(Group C)acted as control groups.Then,three kinds of reconstructive modalities were implanted into segmental bone defect of donator rabbit's radius.Besides these three groups,bone defect model of rabbit's radius without treatment(Group D)represented blank group.The defect-repaired capabilities were assessed by gross observation,radiograph,Single Photo Emission Computed Topography (SPECT)and histological analysis in the 4th week,8th week and 12th week after operation.The rates of bone healing in the different groups were compared each other.Results All defects that had been treated with implants(Group A,B,C)exhibited new bone formation and could attain osseous tissue healing 12 weeks after operation,but defects in blank group(Group D)were repaired only by fibrous tissue.The defects in the Group A regenerated more new bone,bridged earlier and stronger than those in the Group B and Group C.The quantity and rate of new bone formation in the Group B and Group C had no significant difference and the rates of bone healing in different groups showed the same results.Conclusion hBMP-2 gene modified tissue engineerod bone have better potential to form new bone and the rate of bone healing in repairing bone defects is higher,so this way is an optimal kind of material for artificial bone graft.

ALT,tolal bilirubine(TB), PT, NH 4,and blood suger(BG) were monitored. The pathological changes were observed when the canine died,remain alived animal were killed on 7th day and 14th day respectively. EEG was performed on 3rd day after the model eslablished. Results After CCl 4 was injected, the canine showed progressive hepatic failure, ALT, TB and NH rose persistantly, PT prolonged, and BG decreased (P

BACKGROUND:The risk of lower extremity deep venous thrombosis was high in patients with bone metastases. Major surgery is a major risk factor for thrombosis. There was no standard prophylactic regimen available.
OBJECTIVE:To investigate the efficacy and safety of low molecular weight heparins versus rivaroxaban in the postoperative prevention of lower extremity deep venous thrombosis in patients with bone metastases.
METHODS:From January 2010 to December 2013, a total of 73 patients with bone metastasis in spine, pelvis and lower extremities, who underwent open surgery in the Department of Musculoskeletal Tumor, Third Hospital, Hebei Medical University, China, were retrospectively analyzed. The patients were divided into low molecular weight heparins group (n=41) and rivaroxaban group (n=32) according to the prophylactic drugs after surgery.
RESULTS AND CONCLUSION:Nine cases (22%) in the low molecular weight heparins group were found lower extremity deep venous thrombosis, and six cases (19%) in the rivaroxaban group suffered from lower extremity deep venous thrombosis, showing no significant differences (χ2=0.11, P=0.74). The incidences of bleeding events in both groups were respectively 7.32%and 6.25%, showing no significant differences (correctionχ2=0.083, P>0.05). There were no significant differences regarding the levels of platelet, activated partial thromboplastin time and prothrombin time between both groups preoperatively or postoperatively (P>0.05). Therefore, the efficacy and safety of low molecular weight heparins and rivaroxaban in the postoperative prevention of lower extremity deep venous thrombosis were similar. Both could effectively reduce the incidence of deep venous thrombosis, with a relative low risk of bleeding.

Objective To explore and summarize the choices of pedicle skin flaps in repairing cutaneous defect of foot and ankle.Methods Defects of forefoot,pedal dorsum,pedal plantar and ankle were repaired with pedicle skin flaps such as dorsal pedal flap,medial plantar flap,plantar metatarsal flap,fibular hallux flap,tibial flap of 2nd toe,anterior tibial artery flap,posterior tibial artery flap,sural nerve flap,lateral tarsal artery flap,anterior ankle artery flap peroneal artery flap etc.Results Except for necrosis of 2 cases of flap,the other 249 flaps all survived.Blood vessel crisis was induced in 5 patients on 1st postoperative day,and in 2 cases on 2nd postoperative day,by tight package of transplanted skin,which was treated by emergent explorative operation.Finally 135 cases got 3 to 96 months' followed up(average of 16 months).There were 4 cases of medial pedal flap and 3 cases of plantar metatarsal flap received secondary reshaping for treating skin wear out.Nine cases of posterior tibial artery flap,and 6 cases of sural nerve flap were reshaped secondarily to improve bulk shape.Other flaps did not need secondary reshaping.Among them,in medial pedal flap,fibular-side flap of hallux,and tibialside flap of 2nd toe,sensory nerve were all transferred together with the flap,and normal sensory was got,with 4-10 mm two point discrimination.Condusion In covering tissue defects on heel or plantar side of forefoot,medial plantar artery flap is ideal.For defects on plantar side of forefoot,plantar metatarsal flap,fibular hallux flap,tibial flap of 2nd toe have the advantages of wear resistance and nerve innervation.While dorsal pedal flap,anterior tibial artery flap,posterior tibial artery flap,sural nerve flap,lateral tarsal flap,anterior ankle artery flap,and peroneal artery perforator flap have the advantages of large size,thinness,similar color with recipient site,and constant anatomical position,they are feasible for repairing defects on dorsum of foot or near ankle.

ObjectiveTo introduce the new method of full reconstruction for Ⅰ to Ⅲ-degree finger defect.MethodsFor reconstruction of Ⅰ to Ⅱ-degree finger defect, the surgery procedure was as follows:Harvest part of nail,skin and dorsal part of distal phalanx from hallux to form a composite flap,and then the flap was transplanted to the finger stump to reconstruct the defect part of the finger.The design of the composite flap was according to the recipient part. For reconstruction of Ⅲ-degree finger defect, the skin included in the flap could be designed according to the recipient part, but the bone can only be harvested from the fibulodoral part of the hallux and far from the insertion of the extensor hallucis longus tendon, which means the length was limited.If the bone length was not enough,one bone mass with appropriate size and shape was harvested from the iliac bone and connected with the bone of the composite flap. Some cases of Ⅲ-degree finger defect were reconstructed by harvesting interphalangeal joints from the second toes to reconstruct distal interphalangeal joints(DIP). The bone defect was reconstituted by bone mass from the iliac bone to conserve the contour of the second toe.The hallux wound was covered by a local flap or free flap transplantation.ResultsOne hundred and eighteen cases (126 fingers) of Ⅰ-degree defect, one hundred and eighty-seven cases (201 fingers) of Ⅱ-degree defect and 90 cases (111 fingers) of Ⅲ-degree finger defect were applied full reconstruction. All the reconstructed fingers survived completely and the configurations were similar to real fingers. Followed up our work on 150 fingers from a number of patients, between 1 and 11 years after the original surgery.Total ranges of motion of the reconstructed fingers got to over 180°.The reconstructed DIP joints had the range of motion of 15°-40°. The donor halluxes and toes were conserved with the normal length,relatively primary appearance and full function. ConclusionFull reconstruction for Ⅰ to Ⅲ-degree finger defect has great advantages in that the reconstructed finger has very realistic configuration as well as ideal function and the donor hallux is conserve well.

ObjectiveTo explore methods of donor repair of the great toe-nail flap in finger reconstruction surgery.MethodsFrom December 1998 to December 2010, various kinds of flaps were used in 511 donor sites to repair the great toe-nail flaps,including:32 dorsal pedal artery flaps;twenty-four first dorsal metatarsal artery flaps;twenty-one second dorsal metatarsal artery flaps;forteen anterior malleolar flaps;seventeen medial tarsal artery flaps;seventy-nine lateral tarsal artery flaps;one hundred and six plantar metatarsal flaps,seventy-nine flaps from second toe;fifteen flaps from mid/lower leg and 124 freed flaps.ResultsAfter postoperative 6 months to 11 years of follow-up, repaired donor sites of great toe-flaps all survived successfully,with ideal outlook and function.ConclusionThere are many kinds of methods for donor site repair of the great toe-nail flap,and each kind of method has its own advantages and disadvantages. Among these flaps, plantar pedal artery flap and free groin flap are amony the best ones.
