Objective To investigate the anatomic variations of the perforator vessels of anterolateral thigh (ALT) flap and the clinical indications. Methods From March 1985 to August 2004, the anterolateral thigh flapgraft was performed in 112 patients. The clinical data were analyzed. There were 67 males and 45 females, aging from 5 to 65 years with an average of 38.5 years. According to recipient site condition, four methods of flap harvesting were as follows:① 78 received free fasciocutaneous flaps;② 22 received free adipofascial flaps;③ 5 received pedicled island fasciocutaneous flaps; ④ 7 received pedicled reverse-flow island fasciocutaneous flaps. Facial, neck, breast, extremityjoint, plantar, and perineum defects were repaired and the effectiveness and donor site morbidity were evaluated. Results The blood supply of ALT flap came from the descending branch or transverse branch of the lateral circumflex femoralartery. The skin vessels were found to be septocutaneous perforators in 33% of flaps and to be musculocutaneous perforators in 77% of flaps. Of 112 flaps, 107 survived completely, the survival rate was 95.6% with little donor site morbidity. Conclusion ALT flap is a versatile softtissue flap. If refined to perforator flap, it can achieve better results in reconstructing defect and minimizing donor-site morbidity.
Objective To summarize the basic research and the cl inical appl ication of biodegradable interbody fusion Cage. Methods Recent l iterature concerning biodegradable interbody fusion Cage at home and abroad was extensively reviewed, and current developments of the basic research and the cl inical appl ication of biodegradable interbody fusion Cage were investigated. Results Basic research showes that the stiffness of biodegradable interbody fusion Cage is lower than that of metall ic Cage, so it can enhance interbody fusion. As interbody fusion proceeded, biodegradable interbody fusion Cage degrades constantly, but the speed of degradation can not keep in parallel with that of fusion. In addition, the tissue response to degradation products is controversy. Cl inical appl ication showes that the biodegradable interbody fusion Cage can enhance interbody fusion and maintain disc space height. The short term results are good, however, the long term results need further observation. Conclusion Biodegradable interbody fusion Cage can effectively enhance interbody fusion.
【Abstract】 Objective To review the progress of autologous fat grafting of the face and outline different arguments in this field. Methods Recent literature concerning autologous fat grafting of the face was reviewed and analyzed. Results The applications and techniques for autologous fat grafting have been matured increasingly. It not only can adjust the proportion of facial contours, restore tissue volume, but also can improve the local skin texture. Reliable clinical results have achieved in facial augmentation and rejuvenation. Although there are arguments about donor site, harvesting technique, processing technique, and grafting technique, the basic principle is the same. Conclusion From the perspective of evidence-based medicine, clinicians are rich in clinical experience, but objective evidence is insufficient. So further researches should be carried to look for scientific evidences.
To study the effect of intraperitoneal hyperthermic double distiled water and cis-diamminedichloro-platinum(DDP) perfusion to the peritoneal cancerous ascites,intraperitoneal injection of H22 cancer cells (2×107 tumor cell,each mouse) were performed in LACA mice. Five days after cancer cells injection, intraperitoneal perfusion of simple hypertherrnic (43℃) double distiled water(group Ⅰ) isotonic fluid (group Ⅱ ). DDP (group Ⅲ ), and hypertherrnic double distiles water perfusion combined with DDP (guoup Ⅳ ) were performed .The results showed that cancer cells in the peritoneal cavity of LACA mice were seriously damaged, the production of ascites was markedly inhibited and the survival days of LACA mice were prolonged in all groups . .The intraperitoneal hyperthermic double distilled water perfusion with DDP group showed more effective result as compared with the other groups,Only 1 peritoneal implanted dissemination was found after treatment in this group,Basing on the experimental from September 1991 through September 1993,intraperitoneal hyperthermic double distiled water perfusion with DDP was used to treat 32 advanced gastric cancer patients after radical gastrectomy with satisfactory results.

ConclusionsThe clinical application of enteral microecopharmaceutics immunonutrition in the perioperation of colorectal cancer can obviously improve patients' nutritional status and immune function, reduce the stress response, and improve its prognosis, but the use of best dose still need further study.
In order to solve the defect of blood vessel in tissue transplantation and complicated palmar amputation, bridge by "Y" type vein had been used from Jan. 1990 to Jul. 1996. Twenty-three cases were treated. In this series, there were 16 males and 7 females, with ages ranged from 10 to 42 years old. Six cases were the defect of lower legs anterior skin and tibia, 3 cases were the femur fracture with injury of femoral artery and tissue’s defect, 2 cases were defect of five fingers, 12 cases were complicated palmar amputation. RESULT: 15 cases with tissue transplantation and 12 cases with limb replantation were all survival without infection or necrosis. After the following-up for 3 years (ranged from 1 to 5 years), the function of injured limbs were satisfactory, 19 patients had resumed their original work. So, to bridge by "Y" type vein is a good method for repairing the defect of blood vessels in tissue transplantation and complicated palmar amputation, but skilled microsurgery technique is required.

Local hypothermia as a preventive method to reperfusion injury of skeletal muscles was studied. Sixteen Japanese rabbits were divided into four groups at random. Before the tourniquet was inflated, a cold gel pack was applied to the right hind leg of each rabbit for 15 minutes to produce local hypothermic condition, without application of tourniquet the left hind limb was under local hypothermic condition as a control. The duration of tourniquet ischemia was 4 hours, and then reperfusion for one and two hours in the A and B groups respectively; in the C and D groups the duration of ischemia was 5 hours, and reperfusion for one and two hours, respectively. The muscle temperature averaged 16.6 degrees C with a needle thermocouple in the hind limb under local hypothermia. The serum K+, LA, SOD, LPO were determined from bilateral femoral veins, and electron and light microscopic studies of sural muscles were done in the post-reperfusion period. It was found that the K+, LA, LPO were lower than that of the control groups (P lt; 0.01), but SOD was higher than that of the control group (P lt; 0.01). Electron and light microscopic studies showed sight but reversible damage of muscular structure with the possibility of in the hypothermic groups cell regeneration. Basing on this experimental results, this method was applied in 45 cases reparative and reconstructive surgery of limbs. The duration of application of tourniquet averaged 2 hours and 57 minutes, the longest being 4 hours and 31 minutes, when the muscle temperature had reduced to 22.4 degrees C. There were no postoperative complications associated with this technique. Local hypothermia appeared to be a safe and effective method of decreasing the reperfusion damage after ischemia.
Objective To provide the anatomic bases for clinical application of the second dorsal metacarpal artery(SDMA) island flap with double pivot points. Methods The origin,branches and distribution of the recurrent cutaneous branch of the SDMA were observed in 30 adult fresh cadaver specimens, which were illustrated with special dye.Eighteen cases of skin defets of the thumb were repaired with the SDMA island flap. The defect locations were the dorsal part in 11 cases and palmar part in 7 cases, including 3 cases of defect in association with long pollical extensor defect and 2 cases of defect in association with dorsal skin defect of proximal finger. The flap area ranged from 2 cm×3 cmto 3 cm×5 cm. Results The appearance of therecurrent cutaneous branch of the SDMA was observed in all cases(100%), which originated 0.5±0.2 cm distant from the distal intersectiones between the SDMA and the index extensor and disappeared 1.2±0.5 cm distant from the proximal metacarpophalangeal joint. The branches of 1.7±0.7 were seen with a longitudinal fan-like distributionforward proximal part on the deep surface of the dorsal superficial vein. The exradius and the length of the recurrent cutaneous branch of the SDMA were 0.3±0.1 mm and 6.5±0.8 mm, respectively. The transplanted flaps survived in all cases and 16 cases were followed up for 8-14 months. The colour and appearance of the skin were satisfactory. The two-point discriminations were 0.9 mm in 3 cases by bridging digital nerve and 1.1 mm in 9 cases by anastomosing dorsal digital nerve; while the two-point discrimination was 13-15 mm in 4 cases without anastomosing nerve. Conclusion The origin,branches and distribution of the recurrent cutaneous branch of the SDMA is constant, which provide a potentially longer pedicle and increase the possibility to rotate the flap and also avoid the donor skin defect of rotation of the flap.
