AIM: To study the mechanism of protective effect of exogenous carbon monoxide (CO) in the lung injury induced by ischemia-reperfusion (IR) of hind limbs in rats. METHODS: Thirty-two SD rats were randomly divided into 4 groups: control, control+CO, IR and IR+CO. A rat model of ischemia in hind limbs and the reperfusion lung injury was made. The rats in IR+CO and control+CO groups were exposed to air containing 2.5?10~ -8 CO for 1 h before reperfusion or the corresponding control time point, while the other two groups were exposed to the routine air. The lung tissue structure, polymorphonuclear leukocyte (PMN) count, wet-to-dry weight ratio (W/D), malondialdehyde (MDA) content and the animal survival rate were observed. The carboxyhemoglobin (COHb) levels in artery blood were detected with CO-oximeter and the expression of intercellular adhesion molecule-1 (ICAM-1) in the lung was detected by Western blotting. RESULTS: Compared to control, the animal mortality, lung PMNs number, W/D , MDA content and ICAM-1 expression were all significantly increased in IR group. Compared with the IR group, the blood COHb level was significantly increased and the animal mortality, lung PMNs number, W/D, MDA content and ICAM-1 expression were all significantly decreased in IR+CO group. CONCLUSION: These data suggest that exogenous CO attenuate limb IR- induced lung injury by down-regulatiny ICAM-1 expression and suppressing PMN sequestration in the lung following limb IR in rats.

Objective To investigate the selection of operative method and peri operative managements for osteoporotic femoral intertrochanteric fracture in elderly patients aged over 75 years.Methods A total of 132 consecutive patients aged 75-91 years with osteoporotic intertrochanteric fractures from July 2009 to July 2012 were retrospectively analyzed.47 patients were treated with dynamic hip screw (DHS group),44 patients with proximal femoral nail anti-rotation (PFNA group) and 41 patients with Gamma Ⅲ nail (Gamma Ⅲ group).The peri-operative managements,operation circumstance,the time for fracture union,postoperative complications and the degree of functional recovery were analyzed and compared between the 3 groups.Results The mean surgical time was shorter in Gamma Ⅲ nail and PFNA groups than in DHS group [(68.7±9.1) min,(80.5±11.3) min vs (112.2±18.4) min,both P＜0.01].The mean blood loss was less in the Gamma Ⅲ nail and PFNA groups than in DHS group[(156.9±18.5) ml,(183.4±21.3) ml vs (296.2±29.6) ml,both P＜0.01].The mean time for fracture healing was shorter in Gamma [Ⅲ nail and PFNA groups than inDHSgroup [(12.6±2.4) weeks,(13.1±2.4) weeks vs (15.3±3.2) weeks,both P＜ 0.05],and it has no obvious difference between Gamma Ⅲ nail and PFNA groups (P＞0.05).There were significant differences in postoperative complications between Gamma Ⅲ nail,PFNA groups and DHS group (2 cases,3 cases vv 11 cases,P＜0.05,respectively).The mean Harris hip score had no significantly difference among DHS,Gamma Ⅲ nail and PFNA groups (87.4±11.6,90.2±13.0 vs 88.9±12.3,both P＞0.05).Conclusions The 3 operative methods for stable intertrochanteric fracture are feasible and effective in elderly patients,but for unstable intertrochanteric fractures,the treatment with Gamma Ⅲ nail and PFNA has advantages.

Objective To evaluate the clinical effectiveness of double balloon dilation in percutaneous kyphonplasty on curing vertebral?compression fractures. Methods From January 2009 to September 2013, 84 patients (94 vertebral bodies) with vertebral compression were treated by percutaneous kyphonplasty. All were fresh fractures and were injured or obvious low back pain 1 month, accompanied by local tenderness, kowtow attack painful, lumbar mobility, but no lower extremity injury numbness, activities and defecation disorders. After randomization, the double balloon dilation in percutaneous kyphonplasty method was used to treat 44 patients (49 vertebrae). In the process of performing percutaneous unilateral pedicle puncture and balloon dilata?tion of the vertebral body, the balloon has been moved some distance in the vertebral body. Then completed the perfusion of bone cement, vertebral body forming. 40 cases (45 vertebrae) were used conventional unilateral percutaneous kyphonplasty to vertebtal compression fractures. Recorded the operation time, amount of bleeding, bone?cement injection volume. Used visual analogue scale (VAS), the height of the vertebral body and Cobb angle to evaluated the curative effect. Results All 84 patients completed the operation, follow?up time was 22 months (18-24 months). In two mobile open expansion group, the operation time was about 48 min. The amount of bleeding was 8-15 ml. The average bone?cement injection volume was 5.1 ml. No patients quit the study and no bone cement?leakage cases or other side effects were observed , and no clinical accidents occurred. In a single stretching group, 40 cases (45 vertebrae) completed conventional vertebroplasty, the time of 44 min, bone cement average injection rate 3.2 ml, bleeding 10-15 ml. In two mobile open expansion group, the VAS score was 8.5 points, the height of the vertebral body height was 2.1cm, and the Cobb angle was 34°. After operation, the VAS score 2.9 points, the height of the vertebral body 2.8 cm, and Cobb 20° . In the other group, the pain was significantly relieved and the relief was satisfactor after operation.Vertebral height of 2 cm turned to the last follow?up of 2.4 cm. The Cobb angle was 32°, and the last follow?up was 27°. The VAS score, operation time and bleeding volume of the two groups were not statistically significant, and a statistically significant difference of the average bone ce?ment injection volume, postoperative vertebral height and cobb angle improved with statistical significance. A single open group were 2 cases of bone cement leakage and leakage, 1 cases of bone cement tail, the complication rate was 5.6%. Conclusion The application of double balloon dilation in percutaneous kyphonplasty to vertebral?compression fractures improve relocation of verte?bral compression fractures, increase recovery of vertebral height, and more effectively strengthen and stiffen pathological vertebral bodies, while improving kyphosis. Moreover, it can reduce pressure during bone?cement injections, minimizing the chance of over?flow and leakage, as well as the related side effects, but it will also result in an increase of bone cement?injection volume.

Objective To explore the clinical efficacy and indications of kyphoplasty with movement and secondary en?largement of balloon for the compression fracture of vertebral body with ruptured posterior wall. Methods A retrospective analy?sis was carried out on the data of 29 patients (10 males, 19 females;age range:55-86 years old;mean age:71 years old;29 verte?bral bodies in total) who suffered from compression fracture of the thoracolumbar spine and below, and underwent kyphoplasty through the movement and secondary enlargement of balloon within the vertebral body and were followed up from January 2011 to November 2014. These patients had backache, accompanied by lowered support, limitation of movement, no symptom of nervous lesion on both lower extremities and no past history of balloon kyphoplasty. All fractured vertebral bodies were at T 11 or below, in?cluding 1 case at T11, 4 cases T12, 11 cases L1, 9 cases L2 and 4 cases L3. The causes of injury included fall (19 cases), car accident (8 cases) and unknown reasons (2 cases). All patients underwent kyphoplasty with the movement and secondary enlargement of bal?loon within the vertebral body. Photos were taken immediately after the surgery, at 1 month, 3 months, 6 months and 12 months, and these patients were assessed and analyzed in terms of vertebral height, Cobb angle, visual analogue score (VAS) and Oswestry disability index (ODI). Results The operation time (including the formation and solidification of bone cement) of 29 patients was 40 to 65 min and the mean time was 55 ± 7 min;the blood loss during operation was 2 to 15 ml and the mean blood loss was 5 ± 2 ml;the injected volume of bone cement was 2.5-7.5 ml and the mean volume was 5.5±0.5 ml. Post?operative pain was relieved and ambulation was performed under the protection of lumbar orthosis brace. Statstical analysis was conducted on VAS, ODI, vertebral height and Cobb angle before operation and at 1 month, 3 months, 6 months and 12 months after operation, showing statistically significant differences. X ray examination found that there was no alternation or displacement of bone cement location, and no change in vertebral morphology, the vertebral height and cobb angle remained the post?operative status, and posterior wall rupture of the vertebral body was recovered well. CT revealed that the morphology of bone cement was irregular and closely integrated with bone substance, and no cavity or fissure was seen. Conclusion Kyphoplasty with movement and secondary enlargement of bal?loon within the vertebral body has a good, definite clinical efficacy in treating compression vertebral fracture with incomplete pos?terior wall of the vertebral body without obvious displacement of fractured bone and symptom of nervous lesion on both lower ex?tremities. This surgery is easy to operate, and has an immediate analgesic effect, which could recover vertebral height as well as re?duce kyphosis deformity and improve patient’s prognosis.

Objective To evaluate the health-related quality of life ( HRQL) of patients with adolescent idiopathic scoliosis ( AIS) before treatment. Methods Sixty-two female patients with AIS were evaluated using the Chinese version of Scoliosis Research Society's outcomes instrument 22 ( SRS-22) HRQL questionnaire before treatment. The patients were categorized into thFee groups: a mild deformity group with a major curve Cobb angle less than 30° ( n =14),a moderate deformity group with Cobb angles of 30° to 50° ( n =42), and a severe deformity group with Cobb angles more than 50° ( n =6). Results The severe deformity group scored lowest in the self-image domain.There was,however,no significant difference in the functional activity,pain or mental health domain scores between the three groups. Conclusions The Chinese version of the SRS-22 HRQL questionnaire can be used to assess the HRQL of Chinese AIS patients.AIS patients with a major curve Cobb angle more than 50° have relatively low self-image scores.

OBJECTIVE To investigate the characteristics of hypopharyngeal carcinoma detected by narrow band imaging(NBI)endoscopy and evaluate the value of NBI in the early diagnosis of hypopharyngeal carcinoma. METHODS Between December 2008 and July 2009,a total of 46 consecutive patients with hypopharyngeal squamous cell carcinoma were enrolled in this study. High performance endoscopic system equipped with the white light mode and NBI mode was introduced in the examination of pharynx and larynx. The quality of visualization of morphologies of epithelial capillary and demarcation line of each lesion under NBI view was evaluated in comparison with conventional white light endoscopy. RESULTS Among the 46 patients,a total of 86 lesions were detected. The notable characteristic of hypopharyngeal squamous cell carcinoma is the well demarcated brownish area and scattered brown dots. The NBI laryngoscope could provide better visualization of morphologies of epithelial capillary and demarcation line in superficial carcinoma of hypopharynx than the white light mode(P

Phospholipase D (PLD) hydrolyzes phosphocholine into choline and phosphatide acid, and these metabolites play an important role in regulating cell physiology and biochemistry. To study the biological function of phospholipase D3 (PLD3) during the insulin stimulation in C2C12 myoblasts, we constructed PLD3 over-expressed cell lines (C2C12/pPLD3) and investigated the phosphorylation of Akt. The results showed that the level of phosphorylated Akt (P-Akt) was significantly increased in control C2C12 cells when insulin concentration was elevated during cell treatment, whereas the level of P-Akt in C2C12/pPLD3 cells was not changed. When extending the time of insulin treatment, P-Akt level in C2C12/pPLD3 cells was increased around 2 folds, but the total level of P-Akt in C2C12/pPLD3 was still lower than that in control group. 1-Butanol, a PLD inhibitor, could completely block Akt phosphorylation in C2C12 cells that even stimulated by insulin. However, 1-Butanol did not inhibit the Akt phosphorylation in C2C12/pPLD3 cells, but increased the phosphorylation up to 6 folds higher than control cells. The level of Akt phosphorylation in control C2C12 cells was increased significantly when stimulated by phosphatidic acid (PA), while there was no change in C2C12/pPLD3 cells with the similar treatment. When cells simulated by both PA and insulin, P-Akt level in both C2C12/pPLD3 cells and C2C12 cells were down regulated. Our observations indicated that PLD3 over expression may inhibit Akt phosphorylation and further block the transduction of insulin signaling in C2C12 cells.
