Objective To explore the effectiveness of modified Sundaresans method, including exposure through the incision involving both of the sternoclavicular joint and lower cervical region with sternum retention, in the treatment for upper thoracic spinal tumor. Methods From January 1999 to October 2003, 14 patients, 9 males and 5 females, aged from 26 to 65 years with a mean of 43 years underwent the modified Sundaresans procedure. The anterior cervico-thoracic incision was made, the medial part of clavicle close to the sternoclavicular joint was removed. After the exposure of the tumor, the involved vertebral body and contiguous discs were resected, the spinal cord was decompressed, then followed by implanting part of resected clavicle or titanium mesh with an anterior locking plate system. Neurological status was graded according to Frankel grading system. Results The duration of follow-up ranged from 6 months to 2 years with an average of 10 months. This approach displayed the upper thoracic region clearly for removal of the tumor and internal fixation,in avoiding the neurological injury. All patients had their neurological improvement at different level. According to Frankel grading system, one patient improved from grade A pre-operation to B post-operation, while another patient from B to D. Of 2 cases with grade C before operation, one improved to D and the other to E. Of 4 patients with grade D, 2 improved to E, while the other 2 left unchanged. There were 6 cases keeping the same grade before and after operation. Resection of sternoclavicular joint almost had no effect on the movement of shoulder. The abduction of the shoulder joint in 14 patients from 90?-130?(average, 125?) preoperatively became 80?-120?(average, 110?) postoperatively. Conclusion The modified Sundaresans method for the upper thoracic tumors has many advantages, such as satisfactory outcome, less invasion and no loss of the shoulder function. It is especially indicated to the tumors, where the spinal compression is located anteriorly.

Objective To study the cerebral energy metabolism changes of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) through hydrogen magnetic resonance spectroscopy examination (1 HMRS ) and its relationship with partial pressure of oxygen / carbon dioxide tension.Methods Totally 13 cases of AECOPD patients and 10 cases of age-matched healthy people underwent HMRS examination.The ratios of n-acetyl-aspartate(NAA)/creatine(Cr),choline (Cho)/Cr,myo-inositol(MI)/Cr of parieto-temporal and occipital areas of brain were detected.Blood gas analysis were also used to detect partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2).Results NAA / Cr of parieto-temporal and occipital areas of brain (1.32±0.12,1.48±0.12) were lower in AECOPD group than those in control group (1.45±0.11,1.58±0.10) (P< 0.05),MI/Cr (0.23±0.07,0.30±0.11) were also decreased compared with control group (0.40±0.14,0.46±0.12) (P< 0.01),while Cho/Cr of parieto -temporal and occipital areas of brain between the AECOPD group and control group showed no significant difference (P>0.05).NAA/Cr of parieto temporal and occipital areas of brain were positively correlated with PaO2 (r=0.46 and 0.44),and MI/Cr of these areas of brain were also positively related with PaO2 (r=0.63 and 0.50),but MI / Cr of parieto tempora was negatively correlated with PaCO2 (r =- 0.472). Conclusions Cerebral metabolite changes may occur in AECOPD patients,and this has relationship with hypoxia and carbon dioxide retention.

Objective To evaluate neurofunctional and radiographic results of transpedicular screw fixation reduction and anterior column fixation with use of screw-red system in treatment of multiple segment lumbar pedicle and vertebral body fractures combined with spondylolisthesis. Methods A consecutive series of 12 patients with unstable multiple segment lumbar pedicle fracture, vertebral body fracture, spondylolisthesis and neurologic deficit were managed with posterior transpedicular screw fixation including fractured pedicle and anterior screw-rod fixation instrumentation from January 2002 to December 2007. Results Patients were followed up for 24-30 months (mean 26 months). All the patients with incomplete neurologic deficits got improvement by at least one Frankel grade. Transpedicular screw brought satisfactory reduction. At the time of the latest follow-up, no screw breakage occurred. Con-clusions Excellent reduction of unstable multiple segment lumbar pedicle fractures combined with spon-dylolisthesis can attain better reduction and maintenance by means of selective pedicle screw fixation via fractured pedicle and anterior screw-rod instrument.

Objective To observe the changes of the peripheral blood T lymphocyte subsets following acute spinal cord injury and investigate the possible mechanism of these changes. Methods The SCI models of rats were made by Allen's method. Forty SD rats were divided into four groups, ie,normal control group, sham operation group, 100 g·cm group and 200 g·cm group. The expressions of CD4 and CD8 subsets of the peripheral blood T lymphocyte of the injured rats were determined by immunofluorescence labelling and flow cytometry at different times after injury. Results It was found that the expression of CD4 was significantly reduced to (30.40±4.76)% in 100 g·cm group and to (26.54± 9.34) % in 200 g·cm group, which were significantly lower than that of normal control group ( P <0.01 ). At 36 hours after injury, the ratio of CD4/CD8 was significantly reduced to 1.81 ± 0.55 in 100 g·cm group and and 1.29 ± 0.50 in 200 g·cm group, with statistical difference (P < 0.05).Conclusions The immunoreaction is significantly depressed at the early stage of acute spinal cord injury. The severer injury results in more significant decrease of CD4 and ratio of CD4/CD8. The changes of CD4 and CD4/CD8 ratio can be used to indicate the severity of spinal cord injury.

OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.
METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.
RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).
CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

Objective:To study the relationship between dynamic Hoffmann's sign(DHS) and the early diagnosis of cervical spondylotic myelopathy. Methods:Patients with neck, shoulder and back pain (218 cases) were employed in this investigation. Among them, 96 cases had positive reaction to DHS test and they received 3 7 years follow up as study group. The other 122 cases negative to DHS test were taken as control group. The clinical data included the patient's symptoms and signs, sagittal diameter of cervical spinal canal, Pavlov rate, angular displacement and horizontal displacement between cervical vertebral, etc . Results:There were 72 cases in study group developed cervical spondylotic myelopathy and needed operation during follow up. Meanwhile, 11 cases in control group received surgical treatment. The incidence of stenosis of cervical spinal canal, herniation of cervical intervertebral disc and instability of cervical spine in DHS group were significantly higher than that of the control group. Conclusion:DHS is closely related to the onset of cervical spondylotic myelopathy. The patients should be followed up closely if they present positive reaction to DHS, and should be operated on early when their neurological symptom is progressing.

Objective To evaluate the influential factors of iron acquisition during Francisella tularensis LVS infection of mouse macrophages.Methods F.tularensis LVS expressing green fluorescent protein was used to infect murine macrophage J774A.1 cells.Transferrin receptor 1(Tfr1)was detected with mono-antibody and visualized with a goat-anti mouse IgG conjugated to Alexa 594.The expression profile of 5 iron metabolism related genes of J774A.1 murine macrophages uninfected or infected with F.tularensis LVS was determined with real-time PCR.Immunoblot analysis was used to compare the Tfr1 expression of live Francisella infected macrophage with dead bacteria.Tfr1 knock-off in J774A.1 cells was performed with siRNA.The transfected cells were infected with Francisella for immunoblotting and microscopy and infection assay.Results It was revealed that the live vaccine strain of F.tularensis induced the expression of Tfr1 in host macrophages.Gene expression analysis indicated that F.tularensis LVS drove an active iron acquisition program with induction of Tfr1 and iron regulatory proteins(Irp1 and Irp2).It was shown by Western-blotting that the siRNA-Tfrc-1 could knock off about 75% of Tfr1 in J774A.1 cells.It was determined by infection assay that,Tfr1 was knocked off,the bacteria number at 1h infection with Francisella was not different from that of control(F=1.06,P=0.326 5),while it was decreased significantly after 24h of infection(F=24.12,P=0.000 6).Conclusions It is demonstrated that upregulation of the Tfr1 may be mediated by post-transcriptional regulation during early infection,but sustained later through increased expression of Irp 1 and Irp 2.Increased expression of Tfr1 expands the intracellular iron pool through transferrin-mediated delivery and may thus be readily available for uptaking by Francisella.Knocking off the expression of Tfr1 does not affect bacterial invasion.Francisella,however,may fail to proliferate in macrophages in which the expression of transferrin receptor has been suppressed.

OBJECTIVESTo study the diagnosis and treatment for the injury of cervical disc and longitudinal ligament.
METHODSFrom 2001 to 2005, the clinical data of sixty-three patients with cervical disc and longitudinal ligament injury were studied. Early treatment was done based on spinal cord injuries and spinal stabilities by X rays and MRI. Early operation was done in fifty-four cases and early non-operation in nine cases.
RESULTSThe follow-up time was six to forty-one months in all patients. The neurological recovery was found in two of eight complete SCI post-operation, thirty-one in thirty-nine incomplete SCI. Cervical collar or plaster orthotic were used in nine cases with four to six weeks. Evidence of instability was noted in four patients, who were operated with anterior decompression fusion. Neck chronic pain was found in two patients, anterior decompression and fusion was done in one with cervical spinal cord compression.
CONCLUSIONSMRI examination is the most value measure for the diagnosis of cervical disc and longitudinal ligament injury. Early anterior decompression and fusion was an important approach for cervical disc and longitudinal ligament injury.
