The method was established study the influence of different herbal combination with Radix Aconiti in the traditional medical formulae on content of the aconite alkaloids, for elucidating the scientific basis of reducing the toxicity of aconite in traditional Chinese medical formulation. The samples for ESI-MS study were prepared by decocting a mixture of Radix Aconiti Lateralis Preparata ( RALP) with Radix Glycyrrhizae Preparata (RGP) , Radix Paeoniae Alba ( RPA) , Rhizoma Zingiberis (RZ) or Radix Et Rhizoma Rhei ( RERR) , separately, and extracting the residue of the above mentioned mixtures after decocting. The diester-diterpenoid alkaloids (DDAs) was lower in the herb couples of RALP-RGP, RALP-RPA, RALP-RZ and RALP-RERR, and lipo-alkaloids was increased in the herb couples of RALP-RGP, RALP-RPA and RALP-RZ. The reason of reducing toxic effect principle is that the components of RGP, RPA and RZ have ester-exchange reactions with DDAs in RALP to produce lipo-alkaloids of low toxicity in the decocting process of the herb couples. The combination of RALP-RERR can reduce the content of DDAs in decoction and residue due to the formation of water insoluble alkaloid compound.

Objective To investigate the expressions of S100B and calcitonin gene related peptide (CGRP) and the pathologic alterations of the hippocampus in kainic acid (KA)-induced epileptic rats. Methods Male SD rats were randomly divided into control group (n=8) and model group (n=40).Animal models of temporal lobe epilepsy were established by intracerebroventricular injection of KA; the same volume of saline was injected into the rats in the control group. Hippocampal tissues within various phases after seizures (6, 12, 24 and 72 h, and 24 h after the success of model making) were performed Nissl staining, Timm staining and immunohistochemical staining. The expressions of S100B and CGRP were observed, and the pathologic alterations of the hippocampal neurons and glial cells were studied.Results All rat models were successfully induced with epileptic seizures. Nissl staining showed that pyknotic neuronal necrosis appeared in the CA3 area of the hippocampus in the model group with cell body atrophy and disappearance of Nissl bodies 1 week after the injection. Timm staining showed that brown particles showed stripped distribution in the CA3 area of the hippocampus and some brown particles in the molecular layer of fascia dentate. Immunohistochemical staining indicated that significant neurons lost and gliosis appeared after seizures with abundant expressions of S100B and CGRP.Conclusion KA-induced epileptic rats express abundant S100B and CGRP and appear such pathological changes as disappearance of Nissl bodies and mossy fiber sprouting, indicating that both S100B and CGRP participate in the onset of epilepsy.

OBJECTIVETo explore the differential expression of homeobox genes in the normal, wounded human fetal and adult skins and its significance in fetal scarless healing.

METHODSGene chips containing 14 000 human genes were used to investigate homeobox gene expressions of the normal, wounded human fetal and adult skins.

RESULTSThere were significant differences between the expression of homeobox genes, especially for PRX-2, HOXB13, HOXB6 and HOXB7.

CONCLUSIONSThe homeobox gene is in close relation to developmental biology. The different expressions and changes of homeobox genes in the normal, wounded human fetal and adult skin may be a primary cause of different wound healing between fetal and adult skin.

OBJECTIVETo report the reduction mammaplasty with vertical incision and superior wide pedicle.

METHODSTypical Lejour mosque-dome design was performed. The inferior part of glandular tissue and skin were excised. The nipple-and-areola complex (NAC) was elevated to normal position with superior wide pedicle. The breast morphology was modified with vertical scar left.

RESULTS46 patients were treated. 4 patients had unilateral breast reduction. 14 breasts had wound dehiscence. 3 breasts received debridement, others were treated conservatively with dressings. No complete NAC necrosis occurred.

CONCLUSIONSThe reduction mammaplasty with vertical incision and superior wide pedicle is a safe and effective method with a low risk of NAC necrosis.

OBJECTIVETo explore the regional anatomy of the rectum including the perirectal fasciae and spaces.

METHODSTwenty-one cadavers (15 males and 6 females) were embalmed and their vessels were visualized by injection with color dye. From the cadavers, 30 hemipelvis and 6 three-quarter pelvis were harvested. The perirectal fasciae and spaces and the pelvic autonomic nerves were dissected and examined.

RESULTSThree tissue layers were dissected from the inside to the periphery including the proper rectal fascia enveloping the mesorectum, the presacral fascia, and the piriformis fascia fused with the sacral periosteum. The mesorectum comprised 2 parts with the classical posterolateral fat covered by the proper rectal fascia posteriorly and the anterior fat covered by the posterior layer of Denonvilliers fascia anteriorly. Extending anteriorly to the anterior layer of Denonvilliers fascia, the presacral fascia bisected the space between the mesorectum and the piriformis fascia into the retrorectal space and the presacral space. The retrorectal space extended cranially to the left retrocolic space, anterior to the space between the 2 layers of Denonvilliers fascia(prerectal space).

CONCLUSIONSFrom the inside to the periphery, the proper rectal fascia, the presacral fascia, and the muscular fascia are distributed in an annular pattern around the mesorectum. The presacral fascia divides the perirectal space into 2 annular parts, the central retrorectal space and the peripheral presacral space. The retrorectal space is the ideal surgical plane for total mesorectal excision.

BACKGROUNDMore patients receive organ transplantation surgeries due to the advancement in immunosuppressive agents and surgical techniques. Some of those patients may need to undergo plastic or reconstructive surgery. Long-term use of immunosuppressive agents raises some serious problems. Therefore, this study aimed to introduce our experience about the safety and effectiveness of plastic surgeries after solid organ allograft transplantation.

METHODSA retrospective review of 17 transplant recipients who underwent different reconstructive or cosmetic operations was carried out. The subjects included 1 heart transplant, 1 liver transplant and 15 kidney transplant recipients.

RESULTSAll patients tolerated the plastic surgery procedures well. Flaps and skin grafts were the main constructive methods. There were no postoperative infections and wound dehiscence. Transferred flaps survived completely. Skin grafts took well. Three of the cosmetic surgery patients were satisfied with the results.

CONCLUSIONSImmunosuppressed organ transplant recipients can successfully undergo major reconstructive and cosmetic surgery when given special attention.

OBJECTIVETo investigate the correlation of pathology, bone morphogentic protein (BMP) expression, CT value with the ossification of thoracic ligamentum flavum (TOLF) to afford the evidence to choose appropriate treatment methods.

METHODSTwenty-three patients aged 35 - 65 years old had TOLF in my hospital as case. Their courses of disease were 2 months to 9 years. The values of blood calcium, blood phosphorus and AKP in them were normal. The 5 peoples aged 21 - 35 years old who presented fracture of thoracic but not the ligamentum flavum ossification were selected as control. We excluded those who have DISH, ankylosing spondylitis, fluorosis and other disease related with TOLF. The lesion locus were scanned and mensurated by CT. The pathology characteristics were classified into immature ossification and mature ossification by general observation, histology examination. BMP were measured by the immunohistochemical (IHC) staining techniques.

RESULTSThe CT value was significantly higher in the case group (547.2 +/- 131.4) than controlled group (137.7 +/- 10.6) (t = 6.922, P = 0.000). Further, the CT value in the mature ossification (702.9 +/- 17.7) was significantly higher than the immature (480.5 +/- 180.2) (t = 5.623, P = 0.000). In addition, BMP both expressed negative in the mature ossification and the controlled group, but positive in the immature ossification. BMP expression was significantly different between the immature ossification and the mature (chi2 = 70.000, P = 0.000).

CONCLUSIONSThe CT values, pathological types and BMP expression results are similar to evaluate the ossification degrees of ligamentum flavum, and then could be indirectly judged the maturation degrees of TOLF by CT to confirm the treatment methods before operation.
