ObjectiveTo improve the correction rate of clinical, understand transpedicular vertebral intervertebral spinal shortening osteotomy for treatment of clinical efficacy of kyphosis. Methods40 patients with kyphosis,were selected as research objects. beffore and after the kyphosis correction surgery, pain improvement, efficacy and complications were retrospectively studied. ResultsBefore and after surgical correction of spinal kyphosis angle control study showed significant differences. Before and after surgical correction of grading oral pain control study showed significant differences.40 patients,the effects of surgical correction achieved grade Ⅰ ,35 cases(87.5％ ) ,grade Ⅱ in 5 cases ( 12.5％ ), grade Ⅲ and Ⅳ 0. ConclusionIntervertebral vertebral pedicle shortening osteotomy surgery could effectively correct spinal kyphosis, relieve pain and discomfort of patients, and safe, and it was worth to promote in the clinical use.

Objective To explore the relationship of a polymorphism c.757T ＞ C in C-reactive protein gene (CRP) and carotid artery atherosclerosis in patients with ischemic cerebrovascular disease (ICVD).Methods A case-control study investigated 276 ICVD patients and 125 controls matched for age and sex.Genotypes of-757T/C in CRP were analyzed in patients with ICVD using polymerase chain reaction-restriction fragment length polymorphism.The level of serum C-reactive protein was detected by using immune scatter turbidimetry and the intima-media thickness of common carotid artery and internal carotid artery were measured by color Doppler ultrasonography.The relationship between the polymorphism -757T/C in CRP and carotid atherosclerosis was assessed.Results The genotypes of the polymorphism -757T/Cin CRP in the ICVD group (207/276(75.0％),65/276(23.6％),4/276(1.4％)) was significantly different from the control group (75/125 (60.0％),46/125 (36.8％),4/125 (3.2％) ; x2 =9.531,P =0.008),the frequence of T allele in patients with ICVD (479/552(86.8％)) was increased significantly compared to the control group (196/250 (78.4％)),the frequence of C allele in the ICVD group (73/552(13.2％)) was decreased significantly in contrast to the control group (54/250 (21.6％) ;x2 =9.056,P =0.004).Among the patients with ICVD,the level of serum C-reactive protein in patients with-757TC/CC genotype was elevated significantly than that with-757TC/CC ((4.2± 1.6) mg/L vs (2.7 ± 1.9) mg/L; t =5.900,P ＜ 0.01).Logistic regression analysis demonstrated that the-757C allele in CRP was related to the carotid artery atherosclerosis (OR =1.379,95％ CI 0.852-0.864,P =0.023).Conclusions The polymorphism-757T/C in CRP maybe related to the risk of developing ICVD.The frequency of the-757C allele can increase the level of serum C-reactive protein.And this polymorphism may be associated with carotid artery atheroselerosis in patients with ICVD.

Irritable bowel syndrome (IBS) and functional dyspepsia (FD) are common functional gastrointestinal disorders (FGIDs) and account for a large proportion of consulting patients. These 2 disorders overlap with each other frequently. The pathogenesis of IBS or FD is complicated and multi-factors related, in which infectious or non-infectious inflammation and local or systemic immune response play significant roles. There are few studies focusing on the mechanism of inflammation in patients with overlap syndrome of irritable bowel syndrome and functional dyspepsia (IBS-FD). This review focuses on current advances about the role of inflammation in the pathogenesis of IBS and FD and the possible mechanism of inflammation in IBS-FD.

Based on the biomechanical mechanism of human upper limb, the disadvantages of traditional rehabilitation training and the current status of upper limb rehabilitation robot, a six degree of freedom, flexible adjustment, wearable upper limb rehabilitation exoskeleton design scheme is proposed. Firstly, the mechanics of each joint of the upper limb is analyzed, and the virtual prototype design of the whole mechanical structure of the upper limb rehabilitation wearable exoskeleton is carried out by using CATIA three-dimensional software. The tooth transmission of the forearm and the upper arm single row four point contact ball bearing with internal/external rotation and the shoulder flexible passive adjustment mechanism (viscoelastic damper) are innovatively designed. Then, the joints of the upper limb rehabilitation exoskeleton are analyzed, theoretical analysis and calculation of the driving torque, the selection of the motor and gearbox of each driving joint are carried out. Finally, the whole finite element analysis of the upper limb exoskeleton is carried out. The research and experimental results showed that the design scheme of the upper limb exoskeleton assist structure is highly feasible, which can help the patients with upper limb paralysis and motor dysfunction self-rehabilitation.
