Spinal cord injury is a catastrophic injury causing lifelong severe disabilities, and poses a great burden to the individuals, families and society. In order to promote the standardization in treatment of traumatic spinal cord injury, the consensus on the evaluation, treatment and rehabilitation of traumatic spinal cord injury was suggested by experts, who came from authoritative multicenter in China. The expert consensus, which formed a standardization process from the first aid clinical treatment to rehabilitation of spinal cord injury, shall give a better practical guide for clinic and rehabilitation physicians.

The abnormal expression (level and status) of the key molecular targets of tumors is related to molecular targeted therapy response, effect, and prognosis. Therefore, the expression level and status of key molecular targets of tumors must be accurately evalu-ated, regardless of the status before, during, and after receiving targeted therapy. Molecular imaging is a non-invasive method used for qualitative and quantitative research on key molecular targets of tumor in vivo and in real-time. This technique is also employed to screen treatment beneficiaries, guide therapy, and evaluate prognosis. This paper reviews the application progress of molecular imag-ing using various probes in cancer targeted therapy. The clinical value of molecular imaging in tumor targeted therapy is further ana-lyzed to promote the development of novel targeted therapy for tumors.

Objective To investigate the clinical efficacy and safety of testosterone supplement and Mreceptor blockers in the treatment of patients with lower urinary tract symptoms(LUTS)in late -onset hypogonadism(LOH). Methods 28 cases diagnosed as LOH with mild to moderate LUTS were collected.They were given testosterone supplementation (oral testosterone undecanoate capsules,80mg,2 times/d)and M receptor blocker (oral succinate solifenacin tablet,5mg,1 time /d)treatment for 1 -3 months.After treatment for 1 month and 3 months respectively, reviewd PSA,serum total testosterone (TT),international prostate of urinary storage symptoms score (urinary storage IPSS),quality of life (QOL)score,international index of erectile function (IIEF -5)score,maximum urinary flow rate (Qmax),residual urine (Ru)and rectal examination (DRE).The improvement of LUTS before and after treatment was evaluated.Results 1 month after treatment,1 patient was difficult to tolerate the solifenacin side effects and took testosterone supplementation alone.The rest 27 patients were able to take medicine for 3 months.After 1 month and 3 months treatment,the IPSS score had significant differences compared with before treatment[(10.3 ±2.1)points vs (14.2 ±3.3)points and (9.42 ±1.8)points vs (14.2 ±3.3)points,t =13.67,14.72,all P <0.05 ].After 3 months treatment,the QOL and IIEF -5 scores were (2.1 ±0.7)points vs (4.3 ±0.6)points and (16.8 ± 3.6)points vs (11.9 ±2.5)points,Qmax was (12.5 ±5.6)mL/s vs (9.8 ±4.8)mL/s(t =6.42,5.64,14.92,all P <0.05 ),the difference was statistically significant compared with before treatment.There were no significant changes in PSA and RU before and after treatment.All patients had no severe complications such as acute urinary retention.Conclusion Combination of testosterone and testosterone in the treatment of LUTS patients in LOH is safe and effective,and can significantly improve the LUTS and quality of life.

Objective To establish the background information of physiological parameters for germ?free ( GF ) Taihu piglets. Methods In this study we selected 25 days old GF Taihu piglets and 4 conventional ( CV) littermates, the male and female ratio was 1∶3, to measure the normal clinical values of hematology and serum biochemistry, immunoglobu?lin concentration and main organ coefficients. The analysis of relative growths of main organ weight to body weight was con?ducted in the Taihu GF and CV pigs by allometric scaling model. Results (1) Twelve hematological parameters and 8 blood biochemical parameters in the GF piglets were significantly lower than those in CV pigs (P<0?05). (2) The aver?age body weight, IgM concentration of GF pigs and CV pigs had significant difference ( P <0?05 ) , and no mesenteric lymph nodes were found in the GF pigs. (3) The gut weight had the largest allometric association with body weight in the GF pigs, while spleen weight has the largest allometric association with body weight in the CV pigs. Both the weight of heart and stomach in CV and GF pigs had a negative allometric association with body weight (allometric coefficient b<1), respectively. Conclusions Different microbe control grades affect the body weight, hematology and serum biochemistry, expression of immunoglobulin and development of main organs in laboratory pigs.

ObjectiveTo evaluate the relationship between the proliferation of parathyroid cell in rabbit with primary hyperparathyroidism (PHPT) and the bone mineral density (BMD). MethodsEighty adult Chinese rabbits were randomly and equally divided into two groups. The contrast group was fed with normal diet ( Ca ∶ P, 1.0 ∶ 0. 7 ) and the experimental group was fed with high phosphate diet ( Ca ∶ P,1.0∶7.0) to establish the animal model of PHPT. At 3, 4, 5, and 6 months after the diet, bone mineral density of the rabbits was measured by the quantity CT (QCT). Then, the parathyroid and bone of the rabbits were removed for pathological examination. The number of parathyroid cell in PHPT was calculated.Proliferation was determined by immunohistochemistry of proliferation cell nuclear antigen ( PCNA ) and Bcl-2. The t test and Logistic regression was used to analyze the difference of data of two groups. ResultThe number of parathyroid cell in PHPT group was 1.61 times than that in the contrast group[ (673 ± 151 ) HP,(418 ± 25 ) HP,P ＜0. 01]. The rate of PCNA positive-cell was significantly increased in PHPT group than that in contrast group [(50.52 ± 11.62)％o, (26.70 ± 2. 78 )％, P ＜ 0.01], and so was Bcl-2[ (460. 37 ± 190. 05 )‰, (67. 02 ±:4. 38 )％‰,P ＜0. 05]. The value of BMD was significantly decreased in PHPT group than that in contrast group [ ( 152. 5 ± 34. 3 ), ( 188.6 ± 12. 2 ) g/cm3, P ＜ 0. 05]. There was a negative correlation between BMD and PCNA (r ＝ -0. 749, P ＜ 0. 05 ) and between BMD and Bcl-2 (r ＝-0.800, P ＜ 0. 05 ) in PHPT group. ConclusionThe BMD of PHPT is related to the parathyroid cells proliferation which provide a reliable method for early diagnosis of PHPT.

Objective To evaluate the treatment for acute embolism in the extremities and define the primary factors affecting the prognosis. Methods From December 1984 to December 2006,536 patients with acute embolism of extremities were treated. Embolectomy with Forgarty catheters were performed in 507 cases, including salvage surgery in 34 cases and conservative therapy in 29 cases. Results The cure rate, mortality and amputation rate were 76.68%,9.51% and 10.26% respectively. Embolism recurred in 11.7% cases. Cardiopulmonary (27.5% ) and renal failure ( 25.5% ) were main causes of death during perioperative period. No bleeding nor other major complications occurred in 221 patients with atrial fibrillation who routinely received wafarine under proper monitoring. About 25.6% patients underwent heart valves surgery during hospitalization or within one year after discharge. Conclusions Patients suffering from acute embolism of the extremities should receive combination treatment. The main factors affecting the prognosis include time and degree of ischemia, and ischemia-reperfusion injury. Anticoagulant and etiologic treatment should be adopted in those with cardiogenic embolus and atrial fibrillation.
