Objective To compare the immediate effects of extracorporeal shock wave therapy with that of joint mobilization plus short wave therapy in treating scapulohumeral periarthritis, and to elucidate the mechanism of extracorporeal shock wave therapy and how it should be used. Methods Forty-seven patients diagnosed with scapulohumeral periarthritis were selected and randomized into two groups, a treatment group (n = 26) treated with extracorporeal shock wave therapy, and a control group ( n = 21 ) treated with joint mobilization plus short wave therapy. The short form of the McGill pain questionnaire (SF-MPQ) and range of motion (ROM) measurements were used to evaluate shoulder function. Results Compared with baseline, both groups improved significantly af-ter treatment, but the immediate effect in the treatment group was superior to that in the control group. Concln-sions As a safe, time-saving and effective therapy, extracorpnreal shock waves could be used to treat scapulo-humeral periarthritis.

Objective To summarize the experience in application of the bovine jugular vein valved conduct in right ventricular outflow tract (ROVT) reconstruction. Methods Totally 14 patients [6 male, (6.3?5.4) years old] underwent ROVT reconstruction from February 2004 to March 2005 was recorded, and the function of the implanted bovine jugular vein valved conduit was evaluated by Doppler echocardiography one month later after operation. Results There was no perioperative morbidity related to the bovine jugular vein valved conduit. 14 patients were discharged well. One month after operation, echocardiography showed that reconstructed ROVT was patent, and only four implanted conduits had mild regurgition. Conclusion The bovine jugular vein valved conduit provides the favorable hemodynamic performance and thus could be an excellent substitute for the homograft in the reconstruction of ROVT. The mid- and long-term outcomes required further study.

OBJECTIVETo investigate the repair of soft tissue defect at finger tip with square island flap pedicled with skin perforator of digital artery on the distal interphalangeal joint (DIP).

METHODSFrom Jun. 2009 to Mar. 2010, 15 cases with soft tissue defects at 15 fingers tip were treated with this island flaps. The flap size ranged from 1.2 cm x 0.8 cm to 2. 0 cm x 3.0 cm. The defects at donor sites were covered with skin grafts from forearm.

RESULTSAll the flaps and skin grafts survived. 10 fingers in 10 cases were followed up for 6-12 months. The color, texture and contour of the flaps were good. The two-point discrimination distance was 5-6 mm on the directed island flaps, and 7-10 mm on the reverse island flaps. No obvious functional problem was found in DIP motion. The hand function was assessed as excellent in 8 fingers, good in 1 finger and medium in 1 finger.

CONCLUSIONSThe main artery and nerve will not be sacrificed when the island flap is used. The operative procedures are easily performed for the treatment of fingertip skin defect.

OBJECTIVETo explore clinical effects of Ilizarov technique at stage I for repairing tibial post-traumatic osteomyelitis with bone and skin defect.

METHODSFrom June 2010 to December 2013,44 patients with tibial post-traumatic osteomyelitis with bone and skin defect were treated with Ilizarov technique at stage I . Among them, there were 35 males and 9 females aged from 18 to 70 years old with an average of 42.5 years old. Bone defect ranged from 4 to 16 cm, skin defect ranged from 3 cm x 4 cm to 5 cm x 16 cm. The operation was performed debridement thoroughly, removed inflammatory bone section, osteotomy invasively, install circular external fixator by Ilizarow technique; screw nut were rotated at 1 week after operation, and prolonged 0.5 to 1.0 mm everyday. Wound surface, new born callus and bone healing were observed to evaluate clinical effects.

RESULTSAll patients were followed up from 11 to 36 months with an average of 18.5 months. Bone defect after osteotomy was from 6 to 22 cm with an average of 11.5 cm; the time of wound healing time ranged from 21 to 79 d with an average of 38 d; bone defect healing time was from 8 to 15 months with an average of 12.5 months. All patients were cured, no recurrent infection, refracture and shorten of calf deformity were occurred.

CONCLUSIONRepairing tibial post-traumatic osteomyelitis with bone and skin defect by llizarov technique at stage I has advantages of less trauma, low inflammatory recurrence rate, could avoid multiple complex operation, and receive definite curative effect.

Objective:To investigate the feasibility and safety of a new method of natural orifice transluminal endoscopic surgery(NOTES) -totally transtracheal endoscopic thyroidectomy(TTET) .Methods:Three miniature swines and 6 beagle dogs were underwent TTET.Under general anesthesia,special designed endotracheal tube with 2-channel was used and endoscope and instruments were inserted through the respective channel.Incision of tracheal anterior wall was accomplished and partial or subtotal thyroidectomy was performed.Finally,the defects in the trachea were sutured with ENDO STITCH instrument.Results:Partial thyroidectomy was successfully accomplished on 3 pigs and subtotal thyroidectomy was done on 6 dogs.No serious complications such as anoxia,asphyxia,airway obstruction and death occurred during the operation.Animals were sacrificed 2h after the procedure and incision of trachea was found to be closely sutured.There were no subcutaneous emphysema and haematoma formation.Conclusion:Preliminary experimental results showed the feasibility and safety of TTET.Transtracheal access maintains the integrity of cervical tissues and achieves an optimal cosmetic outcome.TTET may open up a new field of NOTES on thyroid surgery.

OBJECTIVETo assess the putative involvement of NF-kappaB and pro-inflammatory cytokines in the pathogenesis of cancer cachexia and the therapeutic efficacy of indomethacin (IND) on cachexia.

METHODSThirty young male BALB/c mice were divided randomly into five groups: A, control; B, tumor-bearing plus saline; C, tumor-bearing plus IND (0.25 mg/kg); D, tumor-bearing plus IND (0.5 mg/kg); and E, tumor-bearing plus IND (2.0 mg/kg). Colon 26 adenocarcinoma cells of murine were inoculated subcutaneously to induce cachexia. Saline and IND were given intraperitoneally daily for 7 days from the onset of cachexia to sacrifice. Food intake and body composition were documented, serum TNF-alpha and IL-6 levels and activity of NF-kappaB in spleen were investigated in all animals.

RESULTSCachexia was observed in all tumor-bearing mice. No difference was found between groups in food intake (P > 0.05). By day 16, body weights of non-tumor mice were about 82.0% of healthy controls (P < 0.01), and the weight of gastrocnemius was decreased by 28.7% (P < 0.01). Gastrocnemius weight was increased markedly (P < 0.01) after treatment of IND (0.5 mg/kg). Tumor-bearing caused a significant increase in serum TNF-alpha and IL-6 levels (P < 0.01). The concentration of TNF-alpha (P < 0.05) and IL-6 (P < 0.01) in tumor-bearing mice was reduced after administration of 0.5 mg/kg IND for 7 days. NF-kappaB activation in the spleen was increased in tumor-bearing mice in comparison with controls. NF-kappaB activity was reduced in mice treated with IND. The maximal inhibition was observed at an dosage of 0.5 mg/kg (P < 0.01). Liner positive correlation was found between NF-kappaB activity and cytokine levels (r(TNF-alpha) = 0.918, P(TNF-alpha) = 0.028; r(IL-6) = 0.884, P(IL-6) = 0.046).

CONCLUSIONSCachexia induced by colon 26 adenocarcinoma cells may be partially attributed to the enhanced TNF-alpha and IL-6 levels which is controlled by NF-kappaB. IND may inhibit the activation of NF-kappaB, decrease serum TNF-alpha and IL-6 levels and thus alleviate the cachexia.
