Cervical spondylotic myelopathy (CSM) is a common cause of spinal cord dysfunction clinical disease. Surgery is the main therapeutic tool for CSM. However, there are obvious differences in clinical functional recovery after operation. For the past few years, the influence factors of prognosis in cervical spondylosis myelopathic has been widely concerned. Age, nerve function, course of desease, imaging findings,surgical method and related factors became the investigative point for prognosis of cervical spondylotic myelopathy. Present viewpoint showed that the older patient, preoperative worse nerve function, longer the course of disease would result in worse outcomes. Imaging examination maybe can indicate the prognosis, but the correlation is unclear. Selection of surgical method and approach should be based on the principles of sufficient decompression, stabilize the alignment of the cervical spine, keeping backward extension of cervical spine, maintain effective decompression, preventing complications. Therefore, the treatment of cervical spondylotic myelopathy should be on the basis of pathogenic condition and imaging examination at early stage and a suitable usrgical procedure should be performed to obtain a better prognosis.

Objective To determine the relationship between polymorphism of apolipoprotein E gene (APOE) and electroencephlogram in patients with mild/moderate traumatic brain injury. Methods (1) Venous blood for 2 ml was collected from 81 patients with mild/moderate traumatic brain injury on admission. APOE genotype was identified by PCR restriction fragment length polymorphism ( PCRRFLP). (2) All the patients were monitored by electroencephalogram for 2-3 times within a week after injury. X2 test and logistic regression analysis via SAS version 8.2 were performed to analyze the results of genotype and electroencephalogram and clinical data. Results The distributions of genetypes and alleles among 81 patients matched with Haldy-Weinberg Law. The findings of electroencephalogram were significantly different between patients with and without APOEε4 (P<0.05). Ten (63%) out of 16 patients with APOEε4 showed an aggravated electroencephalogram,while only 16 (25%) out of 65 patients without APOEε4 showed the same results of electroencephalogram. Logistic regression analyses showed that APOEε4 was a risk factor for electroencephalogram aggravation after traumatic brain injury. Conclusion APOEε4 is a risk factor for electroencephalogram aggravation during acute stage after mild/moderate traumatic brain injury.

OBJECTIVETo study the clinical effect of arthroscopic excision of popliteal cysts through a combined anterior and posterior approach.
METHODSFrom January 2010 to December 2012,20 patients with popliteal cysts were treated with arthroscopic excision. There were 14 males and 6 females, with an average age of 49.5 years old, ranging from 45 to 65 years old. The lump has been found for 4 to 18 months,with a mean time of 12 months. Their mean sagittal diameter was 4.5 cm (ranged from 3 to 7 cm). There were 12 popliteal cysts in the left and 8 popliteal cysts in the right. The main clinical manifestation included lump at popliteal fossa, swelling and pain at knee joint and some extent of dysfunction. All diagnoses were determined according to MRI, which clearly showed the communication of cyst and articular cavity. The cyst was removed under arthroscopy, through the posterior approach and then the intra-articular lesion was treated via the anterior approach. According to Rauschning and Lindgren classification, 2 patients were grade I, 6 patients were grade II, and 12 patients were grade III. The guidelines of Rauschning and Lindgren were used to evaluate the clinical effects.
RESULTSNo complications such as the injury of blood vessel and nerve, or incision infection occurred in all patients. All the patients were followed up, and the duration ranged from 8 to 24 months, with a mean time of 16 months. According to the criteria of Rauschning and Lindgren, there were 14 cases of grade 0, and 6 cases of grade I after operation, which was improved obviously compared with that pre-operation. No cyst reoccurred and the knee joint pain was relieved.
CONCLUSIONTreatment of popliteal cysts with arthroscopic excision through a combined anterior and posterior approach is effective to remove the cyst sac and treat intra-articular diseases simultaneously, resulting in the decrease recurrence rate of cyst.

OBJECTIVETo observe the effects of Shenfu Injection (SI) on immune function in patients during perioperative cardiopulmonary bypass (CPB).
METHODSNinety patients scheduled for CPB were randomly divided into 3 groups, the group A treated with SI before CPB, the group B treated with SI after CPB and the group C (the control group), 30 cases in each group. Counts of leukocyte, neutrophil, lymphocyte and T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) and serum levels of IgG, IgA, IgM, C3 and C4 were investigated at different time-points, i.e. one day before CPB, immediately after anesthesia and finishing CPB, and the 1st, 3rd and 8th post-operational days.
RESULTSIn all the three groups, counts of leukocyte and neutrophil rose immediately after CPB and the high level maintained on the 1st and 3rd post operational days, it somewhat lowered on the 8th day but still higher than that before operation, showing insignificant difference among the 3 groups. As for the other indexes, they declined obviously and immediately after CPB and began to restore on the 8th day to a certain extent, and the restoration were better in the group A and B, as the changes were milder.
CONCLUSIONSI could improve the immune function and reduce the risk of post operational infection in patients during perioperative CPB.

OBJECTIVETo evaluate the clinical efficacy of mini-open repair for the treatment of acute closed achilles tendon ruptures.
METHODSFrom April 2012 and October 2013,14 patients (14 feet) with acute closed achilles tendon ruptures were treated in our department. They were 9 males and 5 females, with an average age of 30.5 years old (ranged, 25 to 49 years old). The interval between injury and operation ranged from 1 to 13 days (8 days on average). A longitudinal incision approximately 1.5 to 2.0 cm in length was made around the ruptured achilles tendon for mini-open repair after insertion of oval clamp. Postoperative rehabilitation was carried out.
RESULTSThe wounds healed at the first stage except 2 cases with slow recovery. All the patients were followed up for 6 to 24 months, with an average of 11 months. According to the ankle-hindfoot scoring system of American Orthopaedic Foot & Ankle Society (AOFAS),the score was 92.71 ± 6.58 (82 to 100).
CONCLUSIONThe surgical treatment of acute achilles tendon rupture with mini-open repair has advantages of little invasion, a low rate of incision problems, quick function recovery, and simple operation, and it is suitable for primary hospital.

China Journal of Orthopaedics and Traumatology 2011;24(9):794-797
The hip arthroscopy develops quickly in the past 20 years. Its use in the diagnosis and treatment of the hip injury get more notably. Many of pathologic conditions previously unrecognized through X-ray, CT or MRI have been diagnosed correctly under hip arthroscopy. The technology has become gradually a golden standard to confirm the hip discords. In the present, the examining path of the hip arthroscopy contains mainly the outside path, the anterior path, the outside-posterior path. The application range of the hip arthroscopy includes the management of labral tears, the femoroacetabular impingement, the ligamentum tear injuries, the chondral lesions, the synovical abnormalities, the intra-articular infection, the loose bodies in the joint etc. The hip arthroscopy is a comprehensive technology. Its superiority can be reflect well if the doctors are familiar with the indication, the contraindication and the operation procedure. And also the thorough physical examination and imaging examination should be made before operation, as well as reasonable and effective postoperative function training should be conducted.

OBJECTIVETo investigate the correlation between dehydroepiandrosterone and arteriosclerosis in premenopausal and postmenopausal women.
METHODSForty premenopausal and 40 postmenopausal women were examined for serum concentrations of dehydroepiandrosterone and intima-media thickness of the carotid artery, and the serum concentrations of lipids, estrogen, endothelin, and E-selectin were also measured.
RESULTSCompared with premenopausal women, the mean intima-media thickness was increased but dehydroepiandrosterone and estrogen levels were decreased in postmenopausal women. A significant inverse correlation was detected between the intima-media thicknesses and dehydroepiandrosterone level. The postmenopausal women had decreased antioxidation and elevated low-density lipoprotein level.
CONCLUSIONArteriosclerosis is more likely to occur in women with low dehydroepiandrosterone level which causes decreased antioxidation and elevation of blood lipid levels.

Vascular endothelial growth factor (VEGF), a central mediator of angiogenesis, not only plays an important role in the pathogenesis of leukemia, but also is an independent prognostic factor in patients with hematologic malignancies, like those in solid tumors. However, the importance of VEGF during differentiation or apoptosis of leukemia cells remains to be elucidated. In order to assess the alternation of VEGF gene expression in the process of all-trans retinoic acid (ATRA)-induced differentiation of NB4 acute promyelocytic leukemia cell line, and a competitor DNA fragment, VEGF gene competative template (T-VEGFDelta) was constructed by using gene recombinant technologies, and a competitive quantitative reverse transcriptase-polymerase chain reaction (cQRT-PCR) method was developed. A standard curve was obtained by co-amplification of serial dilutions of the target nulecules with constant amount of competitive template and this curve was used to detect molecular number of target gene in measuring sample. The surface expression of CD11b antigen and nitroblue tetrazolium (NBT) reduction rate of NB4 cells were also assayed at different time points. The results showed that cQRT-PCR was a sensitive, reliable tool for analysis of VEGF gene expression with a detectable range from 1 x 10(4) to 2 x 10(5) molecules. The number of VEGF gene transcripts detected by means of cQRT-PCR assay was 42.3 x 10(5), 12.6 x 10(5), 3.6 x 10(5), and less than 1.0 x 10(5)/microg total RNA at 0, 12, 24 and 48 hours after ATRA treatment, respectively. This rapid down-regulation of VEGF gene expression, during ATRA-induced NB4 cell differentiation, was accompanied by the up-regulation of CD11b expression and an increased NBT reduction rate. In conclusion, cQRT-PCR method was successtully constructed, confirming that ATRA efficiently repressed VEGF, at the same time, the ATRA might exert an antileukemic effect, other than induction of differentiation via inhibition of angiogenesis.
