OBJECTIVETo investigate the application of the expanding forming under the plate through cervical spatium intermusculare approach to treat multi-segmental myelopathic cervical spondylosis.

METHODSFrom July 2005 to June 2013, 25 patients with multi-segmental myelopathic cervical spondylosis were treated by the expanding forming under the plate through cervical spatium intermusculare approach including 16 males and 9 females with an average age of 56.5 years old ranging from 35 to 78 years old. Among them, 10 cases were onset without causes slowly, 7 cases were onset without causes suddenly, 8 cases were onset after mild trauma or tired. JOA scoring, incidence of postoperative axial symptoms and imaging studies were used to evaluate the effect.

RESULTSTwenty-five cases were followed up for 6 months to 7 years and 6 months with an average of 2 years and 9 months. There were no infection, cerebrospinal fluid leakage after the operation, and complications such as nerve damage were occurred. The operation time was 120 to 150 min, the bleeding was 300 to 500 ml. Imaging examination showed vertebral canal sagittal diameter increased, the vertebral canal increased significantly in the cross sectional area of the spinal cord, cervical curvature was straighten in 4 cases (2 cases of them became normal sequence). There were no more cases of cervical protruding and segmental instability increased. Postoperative walking ability enhanced, the finger activity of majority of patients improved on flexibility, grip strength, and accuracy of using chopsticks improved, numbness and chest waist band feeling had different degree of reduce, preoperative urine impairment were improved to varying degrees. Preoperative JOA scores were 3 to 13 points with an average of (8.86 ± 4.25) points; Postoperative 12 months' JOA scores were 7 to 17 points with an average of (13.76 ± 3.56) points, period was 60.19% in average, JOA score had statistically difference between before and after operation (P < 0.05). The result were excellent in 14 cases, good in 6 cases, and fair in 4 cases and poor in 1 case.

CONCLUSIONApplication of the expanding forming under the plate through cervical spatium intermusculare approach to treat multi-segmental myelopathic cervical spondylosis, through muscular clearance, can retain complete cervical back muscle, maintain stability of cervical spine, and vertebral canal can get effective decompression at the same time.

OBJECTIVETo explore the surgical method and its effects of adjacent spinal segment degeneration after anterior cervical fusion.

METHODSFrom March 2000 to March 2011, 27 patients with spinal segment degeneration who had accepted the operation of anterior cervical fusion were treated with surgical treatment. There were 16 males and 11 females with an average age of 55.3 years (ranged from 48 to 72 years). JOA scores and image examination were used to evaluate the clinical effects.

RESULTSAll patients were followed up for 1.8 to 7.2 years with an average of 3.6 years. All pathological segments obtained fully decompression with good spinal bombe, no internal fixation loosening and cervical spine instability were found. Nerve root pain had disappeared and nerve function had significantly improved. Before operation, 3 days after operation and at last follow-up, JOA scores were 9.15 +/- 3.46, 13.96 +/- 2.79 and 13.52 +/- 2.91, respectively, and there was significant difference between preoperation and postoperation (P < 0.05). Intervertebral height and physiological curvature improved obviously than preoperation (P < 0.05).

CONCLUSIONIn order to relief spinal compression and rebuild spinal stability, a surgical treatment will be recommend to adjacent spinal segment degeneration combining spinal nerve symptoms and physical sign as soon as possible. Selecting an appropriate surgery to treat different compressed segment would receive satisfactory results.

Fanconi anemia (FA) is an rare autosomal recessive inherited disease which manifests progressive marrow failure, congenital bone malformation, high risk to cancers and so on. Chromatin of FA cells display auto-instability and high hypersensitivity to interstrand DNA cross-links such as mitomycin C. As normally FA develop into acute myeloid leukemia easily, it has been regarded as pre-leukemia state. Till now 11 FA genes have been found and play a role in sustaining stability of gene groups through the same mechanism. As an active connecting protein, FANCF protein play an important part in correct FA complex formation. Which makes FANCD2 single ubiquitin. Ubiquitin FANCD2 induces chromatin and BRCA1 interact, and repair injured DNA. FA gene defect makes gene group instable and increases the risk of chromatin collapse, which finally leads to acute myeloid leukemia and myelodysplastic syndrome.

The da Vinci robotic surgical system has the advantages of three-dimensional vision and high degree of accuracy,flexibility and repeatability,which makes surgical procedures such as digestive tract anastomosis easier to conduct under minimally invasive conditions.In this article,the feasibility and principle of digestive tract anastomosis and the procedures of pancreaticojejunostomy and pancreaticogastrostomy by the da Vinci robotic surgical system are introduced,so as to improve the quality of anastomosis and reduce the incidences of postoperative complications.Compared with traditional laparotomy,da Vinci robotic surgical system simplified the surgical procedures and reduced the trauma,which is suitable for digestive tract anastomosis in pancreatic surgery.The method of pancreatic anastomosis should be selected in consideration of the condition of patients,surgical procedure and the experience of surgeons.

Objective To explore the incidence risk of postoperative delirium in different underlying diseases and the effective measures of postoperative recovery.Methods 978 cases of emergency surgery,included acute abdomen 324 cases,358 cases of cardiovascular disease,296 cases of cranial trauma.To analyze preoperative underlying diseases,we observed the incidence rate of postoperative delirium,and the efficacy of different care on delirium recovery was compared.Results There was a higher incidence rate of postoperative delirium in patients with coronary heart disease,high blood pressure and emphysema (P ＜ 0.05),especially in patients with multiple disease (P ＜0.01).And effective psychological intervention could increase the recovery rate of delirium.Conclusion The preoperative underlying diseases has a significant impact on the occurrence of postoperative delirium,and the psychological intervention has good effect on the recovery of delirium.

Methods Nitromethane,nitroethane,1-nitropropane,2-nitropropane in the air of workplace were collected by active carbon tube,desorbed in ethyl acetate solution and detected by capillary gas chromatography (GC-FID). Results The linear concentration range of nitromethane,nitroethane,1-nitropropane,2-nitropropane was 43.2-345.3,177.6-1 421.0,68.5-547.7,24.1-192.4 ?g/ml respectively and the relative standard deviation was 1%-5%. Sampling efficiency was 100%,desorption efficiency was 91%-93%. The sample could be resaved at 4-10 ℃ for 5-7 days. Conclusion The method is applicable to determination of nitromethane,nitroethane,1-nitropropane,2-nitropropane in the air of workplace.

Objective To investigate the changes of liver function and white blood cell of patients with liver cirrhosis,portal hypertension and secondary hypersplenism underwent laparoscopic splenectomy(LS) and open splenectomy(OS).Methods We analyzed 76 clinical data of patients with liver cirrhosis,portal hypertension and secondary hypersplenism,among those 27 underwent LS,49 OS from Mar 2003 to Mar 2006 retrospectively.Blood samples were obtained and analyzed preoperatively and postoperatively on days 1,3, and 7,including alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBil),directed bilirubin(DBil) and white blood cell(WBC).Results Between LS and OS,the serum levels of Tbil and Dbil had significant difference on the 1st postoperative day(P

As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.
