Chinese Journal of Trauma 1993;0(06):-
Objective To explore the causes and treatment of gastrointestinal complications after anterior approach for thoracolumbar fracture and dislocation.Methods A retrospective analysis was carried out in 153 cases with thoracolumbar fracture and dislocation undergone anterior approach from Jan- uary 1999 to October 2003.Postoperative gastrointestinal complication was seen in 15 cases including sev- en with dynamic intestinal obstructions,three with stress ulcer,three with intestinal bacteria imbalance, one with tuberculosis peritonitis resulted from dissemination of primary tuberculosis,and one with acute relapse of chronic appendicitis.Results All patients were effectively cured by using corresponding methods in regard of different causes.Conclusions(1)Gastrointestinal complications following ante- rior approach for thoracolumbar fracture and dislocation are mainly resulted from following causes,ie,se- rious primary trauma,primary gastrointestinal vegetative nerve injury or that caused by surgical operation, intraoperative contusions of abdominal viscera,postoperative retroperitoneal hematoma,acute lesion of gastric mucous membrane as well as imbalance of intestinal flora.(2)Correct treatment of primary trau- ma,meticulous operation,reasonable utility of antibiotics and appropriate management can effectively prevent and control gastrointestinal complications.

Objective To study the possible relationships between expression of matrix metalloproteinase(MMP)2,9 and the pathogenesis of preeclampsia in which trophoblast invasion is impaired. Methods MMP-2,9 expression were detected by immunohistochemistry streptavidin-biotin complex (SABC)method in 20 normal term placentae and 20 preeclampsia placentae,respectively.In addition, mRNAs for MMP-2,9 were analyzed by real time PCR in both groups.Results The intensities of both MMP-2 and MMP-9 immunostaining in preeclampsia placentae were significantly declined compared to those of normal term placentae(P

Objective To test the hypothesis that homocysteine can decrease MMP-2 and MMP-9 expression in cultured trophoblasts of early pregnancy and that homocysteine can prevent trophoblasts invasion in the early stage of preeclampsia.Methods Cytotrophoblasts from early pregnancy were isolated and cultured.Trophoblasts were treated with or without Hcy(1 mmol/L)for 48 hour,and real time RT-PCR and gelatin zymography were used to quantify the mRNA and protease activity of MMP-2,-9.Results Treatment with Hcy(1 mmol/L)induced a decrease in MMP-2 mRNA by 21% and MMP-9 mRNA by 11%.At protein level MMP-2 expression decreased 14% and MMP-9 expression decreased 52% compared with control.Conclusions Homocysteine can decrease MMP-2,-9 expression in trophoblasts of early pregnancy and influence its invasion process.
5.Clinic applications of vascularized plantaris tendon grafting.
Chinese Journal of Plastic Surgery 2003;19(4):251-253
OBJECTIVETo study a new method of the vascularized plantaris tendon transferring.
METHODSThe vascularized plantaris tendon was elevated with the pedicle of the fascial perforating vessel or a small segment of the posterior tibial artery, which was transplanted to the wrist to repair the tendon defects of the flexor pollicis longus or the flexor digitorum muscle resulted from electric injury. According to the defects, the plantaris tendon can be used together with the skin, fascia, or both as a composite flap. 7 cases received the operation with complete survival of the flap.
RESULTSPostoperative follow-up showed satisfactory results in the 7 cases. Through physical exercises, the patients obtained increased joint motion and better function of the hand.
CONCLUSIONThe vascularized plantaris tendon has many advantages, including easy to harvest, easy to plerosis the donor site, little affect to a main vessel, able to repair the complex defects. This method has great potential for applications.

Objective To observe the effect of early rehabilitation therapy on recovery from reoperation for recurrent lumbar disc herniation (RLDH).Methods Sixty-five cases who received surgery for RLDH between 2007 and 2009 were randomly divided into a rehabilitation group and control group.Both groups were treated with the same surgical approach and routine treatment.Early and comprehensive rehabilitation therapy was provided in the rehabilitation group during the perioperative period,including preoperative and postoperative muscle strength training,postoperative sitting and standing balance training,and acupuncture.The control group was instructed only in general exercise.Before the operation and 2 weeks and 3,6,12 and 24 months afterward,the surgical outcomes of all cases were assessed using the JOA score and the improvement rate in the JOA score.Any postoperative complications and intervertebral fusion were also observed.Results The average postoperative JOA scores of both groups were significantly higher than their preoperative scores.At all of the time points after the operation,the average JOA scores and all improvement rates in the rehabilitation group were significantly higher than those in the control group.Postoperative complications such as deep venous thrombosis,urinary retention and constipation were significantly less among the rehabilitation group than among the controls.All the intervertebral bone implants were well fused on time.Conclusion Early rehabilitation can significantly improve the effectiveness of RLDH reoperation and reduce the incidence of postoperative complications.It is recommended for clinical application.

OBJECTIVETo investigate the reconstruction of acquired orbital deformities.
METHODSThrough coronal incisions, subciliary incisions and buccal sulcus incisions, or periorbital wound, the displaced orbital walls were repositioned after osteotomy. And the mandibular outer cortex was used to repair the bone defect, so as to restore the orital integrity.
RESULTSFrom Sept. 2002 to Jun. 2006, 64 patients with acquired orbital deformities were treated. The integrity of orbit and eyeball location recovered very well.
CONCLUSIONSRestoration of the orbital integrity is the key to the treatment of acquired orbital deformities. The periorbital deformities should be corrected after osteotomy with mandibular outer cortex for bone defect.

Fragile X syndrome (FXS) is one of the most prevalent mental retardations. It is mainly caused by the loss of fragile X mental retardation protein (FMRP). FMRP is an RNA binding protein and can regulate the translation of its binding RNA, thus regulate several signaling pathways. Many FXS patients show high susceptibility to epilepsy. Epilepsy is a chronic neurological disorder which is characterized by the recurrent appearance of spontaneous seizures due to neuronal hyperactivity in the brain. Both the abnormal activation of several signaling pathway and morphological abnormality that are caused by the loss of FMRP can lead to a high susceptibility to epilepsy. Combining with the research progresses on both FXS and epilepsy, we outlined the possible mechanisms of high susceptibility to epilepsy in FXS and tried to give a prospect on the future research on the mechanism of epilepsy that happened in other mental retardations.

OBJECTIVETo summarize clinical results of the microdecompression for the treatment of intraforaminal lumbar disc herniations.
METHODSFrom September 2005 to May 2013,16 patients( 12 males, 4 females)with intraforaminal lumbar disc herniations underwent microdecompression, ranging in age from 32 to 56 years old with a mean of 38.6 years old. The lumbar disc herniations were located at L(3,4). in one patient, L(4,5) in 10 cases and L5S1 in 5 cases.
RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months, with a mean period of 36 months. According to Macnab evaluation, 12 cases got an excellent result, 4 good. No apparent complications related to the technique occurred. Satisfactory clinical results were obtained in this series.
CONCLUSIONMicrodecompression may be particularly useful in the treatment of intraforaminal lumbar disc herniations. The microdecompression procedures are more likely to be well tolerated by older patients.
