BACKGROUND: Denervated muscular atrophy is refractory in clinical treatment. To date, there is still no effective treatment for this disease. OBJECTIVE: To observe the influence of two-division muscular transplantation with the pedicle of blood vessels and nerves on denervated muscular atrophy so as to explore a new thought for denervated muscular atrophy. DESIGN, TIME AND SETTING: Controlled animal trial was performed at the Department of Hand Surgery, Drum Tower Hospital of Nanjing University of Medical College between July 2006 and December 2007. MATERIALS: Thirty clean-grade healthy Wistar rats, weighing 250 g, irrespective of gender, were selected. METHODS: Gastrocnemius muscle denervation models were established in both lower extremities. At the experimental side, two incisions were made in 1/3 gastrocnemius muscle of the right side, and the pedicle of the blood vessels and nerves was transplanted into the lateral head of gastrocnemius. While in the control side (left side), gastrocnemius muscle was only disconnected. Samples were harvested at 4, 8, and 12 weeks postoperatively. MAIN OUTCOME MEASURES: Muscular appearance and ultrastructure were observed; muscle fiber circumference and cross-section area and collagen fiber content were measured. RESULTS: The gastrocnemius muscle at the experimental side appeared plump and elastic with acceptable color, while the muscle became atrophy with pale appearance at the control side. Circumference and cross-section area of the muscle fibers at the experimental side were significantly larger than the control side (P

Objective To evaluate the clinical results of limited Smith-Petersen approach in the treatment of posterior dislocation of hip with femoral head fracture (Pipkin fracture of types Ⅰ and Ⅱ).Methods From February 2008 to July 2013,21 patients with Pipkin fracture of types Ⅰ and Ⅱ were treated at our department.They were 16 men and 5 women,with an average age of 39.2 years (range,from 19 to 56 years).The left hip joint was affected in 8 cases and the right in the other 13.The interval between injury and surgery varied from 2 to 7 days (mean,4 days).According to the Pipkin classification,there were 11 cases in type Ⅰ and 10 in type Ⅱ.All the fractures were fixated via the limited Smith-Petersen approach.Results The patients were followed up for 11 to 29 months (mean,17.4 months).All the fractures healed after an average of 15 weeks (from 12 to 19 weeks).According to their Thompson-Epstein scores of clinical and radiological outcomes at the final follow-ups,7 cases were excellent,9 good and 5 fair,giving a rate of excellent to good of 76.2％.Avascular necrosis of the femoral head occurred in 3 cases and osteoarthritis in 2.No infection or limb deep vein thrombosis was observed.Conclusion For Pipkin fractures of types Ⅰ and Ⅱof,limited Smith-Petersen approach can provide satisfactory exposure which leads to reduced soft tissue injury,better reduction and fixation,and fewer complications as well.

Objective To investigate the anatomical characteristics and clinical application of the distal musculocutaneous perforators derived from the descending branch of lateral circumflex femoral artery in the anterolateral thigh flap transplantation. Methods From July 2007 to December 2009, the anatomic variations of musculocutaneous perforator were investigated in 96 cases who received anterolateral thigh flap and 10 preserved cadavers. Thirty-five cases who received the anterolateral thigh flap using the distal musculocutaneous perforators were included in the study. There were 19 males and 16 females. The age ranged from 28-55 years old, with an average of 38.5 years old. Single flap was used in 20 cases while lobulated flap in 15 cases. Single flap area ranged from 7 cm×15 cm to 9 cm×25 cm, lobulated flap ranged from 5 cm×7 cm to 8 cm×20 cm. Results The cadaver study found that the most musculocutaneous perforators were concentrated in the far fourth of the anterolateral thigh region. The musculocutaneous perforators commonly arose from the the lateral femoral circumflex artery. The perforator arose directly from the femoral artery or the deep femoral artery in one case separately. In the clinical study, 2-5 musculocutaneous perforators were found in 94 cases but not in the other 2 cases. The descending branch of lateral circumflex femoral artery became the direct m musculocutaneous perforator. The proximal intermuscularseptum perforator was found in 2 cases. Postoperative follow-up time ranged from 6-11 months. All flaps survived in the follow-up.Marginal necrosis was found in 3 cases. Only 1 case had complained of knee joint instability. Conclusion The results of this study suggest that the vascular anatomy of the distal musculocutaneous perforator was reliable. The perforator may serve as an option for proximal one in anterolateral thigh flap transplantation.

Objective To observe the effect of hyperglycemia on intracranial pressure (ICP) and neurological outcome following severe brain injury. Methods A retrospective review was done on 79 cases with severe traumatic brain injury (with no history of diabetes or important extracranial complications) who underwent craniotomy for evacuation of intracranial hematoma and were divided into two groups based on Glasgow outcome scales (GOS) score, ie, favorable group with GOS of 5 or 4 and unfavorable group with GOS less than 3. Statistical analysis of data was accomplished by using SPSS 11.5 software. The outcome was assessed at the 6th month after injury. Results A significant correlation was found between ICP levels and admission or postoperative glucose values. The unfavorable group had significantly higher glucose levels both on admission and after operation compared with the favorable group, with statistical difference (P

Objective To observe the effect of acupuncture at Tianzhu (BL10) on Blood Stasis Type lumbar disc herniation (LDH). Methods From October, 2013 to October, 2015, 108 LDH cases were randomized into observation group (n=53) and control group (n=55) in accordance with the order of visiting. The observation group received Tuina and acupuncture mainly at Tianzhu, while the control group only received Tuina, for four weeks. The clinical efficacy and improvement of Japanese Orthopaedic Association (JOA) scores were record-ed, and the Visual Analogue Scale (VAS) and serum levels of interleukin-6 (IL-6) were measured before and after treatment. Results The VAS score and IL-6 content decreased in both groups after treatment (t>4.220, P<0.001), and decreased more in the observation group than in the control group (t>3.745, P<0.001). The total effective rate was 94.34% in the observation group, more than 81.82% in the control group (χ2=3.997, P=0.046). The incidence of impromvement of JOA scores was 90.57%in the observation group, more than 76.36%in the control group (χ2=3.920, P=0.048). Conclusion Acupuncture at Tianzhu based on Tuina is more effective on Blood Stasis Type lumbar disc herniation, in term of pain and function, which may relate with decrease of the level of IL-6.

Polybrominated diphenyl ethers (PBDEs) is a kind of important industrial flame retardants,which widely exists in the environment and biosomes.Some researches have indicated that PBDEs is toxic to the nervous system of animals through affecting the release of neuroendocrine hormone,the signal transduction pathways,the transmission of neurotransmitters,the expression of key proteins in the nervous system,and the apoptosis of neuronal cells.Data from environmental monitoring indicated that environmental exposure to PBDEs in China exists,but the research on the effect of PBDEs on nervous system is very limited,which calls for attention.This article summarized researches on the mechanism of neurotoxic effects induced by polybrominated diphenyl ethers from the aspects such as the release of neuroendocrinal hormone,the signal transduction pathways,the transmission of neurotransmitters,the expression of key proteins in the nervous system,and the apoptosis of neuronal cells,and some ideas about the direction of related researches were presented.

Objective To introduce ramified anterolateral femoral flaps pedicled with different musculocutaneous branches used for primary repair of soft-tissue defects at different regions of extremities. Methods From January 2008 to April 2009, 15 patients, 10 males and 5 females, were treated with an-terolateral thigh flaps for their soft-tissue defects at limbs which involved 4 hands, 6 feet and 5 legs and an-kles. Different shapes of anterolateral thigh flap were designed according to clinical anatomy and particular conditions of blood vessels and musculocutaneous branches in different cases. The flaps were ramified into 2 independent free flaps to repair 2 independent defects. The maximum distance between 2 defects was 8 cm. The area of defect ranged from 3.0 cm×3.5 cm to 8.0 cm×11.5 cm, and the flap area from 5.0 cm×5.0 cm to 9.0 cm×15.0 cm. Results According to clinical anatomy, the presence of sarco-cutaneous branches was 100%. The source blood vessel of the flaps was quadriceps artery of femur. The 15 patients were followed up from 3 to 8 months. The tissue grafts all survived and the flaps primarily healed at the recipient site. Revisions were done 3 weeks to 3 months after the primary operation to thin down the clumsy skin flaps in 6 cases, The shape and texture of the flaps were satisfactory. Conclusion Ramified anterolateral femoral flaps pedicled with different musculocutaneous branches provide an ideal way of repairing severe and complex soft-tissue defects at extremities.

Objective To study the clinical value of grafting the musculocutaneous flap with uncovered in the special region to treat the open fracture and infection of tibia. Methods Twenty-eight patients including 19 males and 9 females with ankle and leg tissue defect were applied to graft the musculocutaneous flap with uncovered in the special region from July 2007 to January 2010. The tissue defeat in proximal part of the tibia were 6 cases, and 21 cases in middle and distal part, 1 case almost in whole part of the tibia. The bone occurred a defeat and infection in 23 cases, the bone necrosis occurred in 5 cases. The patients treated with iliac bone flap were 5 cases, anterolateral thigh flap were 21 cases, anterolateral thigh flap combined with fibula flap were 2 cases, the flap were transplanted by anastomosis in 26 cases. Results The tissue grafting were all survival and the survival rate were 100%. The callus formation were appear after operation from 3 to 6 months, and necrosis bone tissue almost were abstracted about 6 months. The wound were primary closure and not happened infection in 26 cases, the wound appeared infection under deep tissue in 2 cased,but being cured after 6 months by operation. The 21 patients were followed up from 3 months to one and helf year. The long-term was satisfaction and the donor area was perfect. Compared with closed graft, its area of the flap was small and need spend little time to treat the repair the defeat, and harness to recover the healthy of body and mind, also decrease the chance of infection in deep tissue. Conclusion It is demonstrated that grafting the tissue flap with uncovered in the special region is an ideal approach to treat the open fracture and infection of tibia.
