Neurologic complications are rare but devastating events after scoliosis surgery; a thorough preoperative work-up and effective intraoperative monitoring of the spinal cord may reduce the incidence. This review discusses the incidence, preoperative work-up, intraoperative monitoring, and managing strategies for neurologic complications of scoliosis surgery.

Fibroblast growth factor receptor 3(FGFR3)plays important roles in cell proliferation,diffe rentiation,and angiogenesis.Recent studies have demonstrated that FGFR3 is associated with progression of breast cancer and has effects in endocrine therapy resistance breast cancer.It has also been showed that FGFR3 is correlated with breast cancer prognosis.

Objective To determine whether left ventricular Tei Index evaluate the cardiac function and prognosis of patients with sepsis-induced cardiomyopathy (SIC).Methods A total of 86 patients with septic shock combined with SIC in the emergency department of Beijing Chaoyang Hospital affiliated to Capital Medical University from July 2014 to June 2016 were recruited and divided into non-survival group (n=35) and survival group (n=51) according to 28-day follow-up.Left ventricular Tei Index, BNP, cTNI and left ventricular ejection fraction within the first 24 h after admisson were detected and compared between the two groups.The correlations of left ventricular Tei Index to BNP, cTNI and ejection fraction were analyzed.The receiver operating characteristic curves (ROC) were constructed to analysize the value of Tei Index in evaluating the cardiac function and prognosis.Results The patientsin the non-survival group had a higher Tei Index compared with that in the survival group [(0.75±0.13) vs.(0.51±0.09), P<0.05].The Tei Index of SIC patients was significantly positively correlated with BNP and cTNI (both P<0.05), and significantly negatively correlated with ejection fraction (P<0.05).The AUC of Tei Index for predicting 28-day mortality in SIC patients was high comapred with that of BNP, cTNI and ejection fraction.Conclusion The left ventricular Tei Index has a reliable value in evaluating the cardiac function and prognosis of patients with SIC.

Objective:To investigate the variations in ocular biometry and its influencing factors in adult Tibetans of Lhasa.Methods:A cross-sectional study was adopted.A total of 100 consecutive adult Tibetans (100 eyes) with cataract, who were treated in Tibet Autonomous Region People's Hospital from March 2017 to July 2017 were enrolled, including 51 males and 49 females, with an average age of (63.38±12.80) years.The subjects were divided into two groups, with 57 subjects (57 eyes) older than 60 years in the elder group and 43 subjects (43 eyes) younger than 60 years in the youth group.Corneal curvature, corneal astigmatism, anterior chamber depth and axial length of subjects were measured and compared with those of Beijing population which were used as standardized data of Han Chinese.The differences in ocular parameters associated with age and gender were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of Tibet Autonomous Region People's Hospital (No.ME-TBHP-21-KJ-005).Written informed consent was obtained from each subject prior to any examination.Results:The mean corneal curvature, corneal astigmatism, anterior chamber depth and axial length of the 100 Tibetans were (43.68±1.62)D, 0.750 (0.375, 1.000)D, (3.05±0.41)mm, (23.07±0.86)mm, respectively.The axial length of Tibetan was shorter than that of Beijing Han people and the difference was significant ( t=2.65, P<0.01).Corneal astigmatism of the elder group was higher than that of youth group and the difference was significant ( t=2.11, P<0.05).There were no significant differences in corneal curvature, anterior chamber depth and axial length between the elder group and youth group (all at P>0.05).The anterior chamber depth and axial length of males were much longer than those of females, and the differences were significant ( t=2.71, 2.25; both at P<0.05). Conclusions:In adult Tibetan population, the axial length is short, and the anterior chamber is deep.The corneal astigmatism increases with age and there is a gender difference in axial length and anterior chamber depth.

Background and purpose:Breast cancer as one of the most common malignant tumor among women in China, it accounts for 12.2% of all newly diagnosed breast cancers and 9.6% of all deaths from breast cancer worldwide. The aim of this study was to investigate the relationship between single nucleotide polymorphisms(SNPs) in 2q35rs13387042and 8q24 rs13281615and the risk of breast cancer in Han premenopausal women of Northern China. Methods:280 patients with breast cancer and 287 healthy controls in premenopausal state were genotyped for SNP 2q35rs13387042and 8q24 rs13281615 by the SNaPshot method, and compared the different genotypes and alleles with relation to breast cancer risk.Results:Differences of 2q35 rs13387042 genotype frequencies between breast cancer and control were signiifcantly different (P=0.017). No statistically signiifcant difference of 8q24 rs13281615 genotype frequencies between breast cancers and controls was found (P=0.967). The results of logistic regression showed that the carriers of GA genotype and GA+ AA genotype increased risk for breast cancer compared to the carriers with 2q35 rs13387042 GG genotype(OR=1.793, 95%CI: 1.177-2.733,P=0.007;OR=1.691, 95%CI: 1.122-2.550,P=0.012), but not the carriers of AA genotype; Compared with G allele, A allele signiifcantly increased the risk of breast cancer(OR= 1.505, 95%CI: 1.033-2.193,P=0.033). The carriers of AG genotype or GG genotype or AG+GG genotype did not confer risk for breast cancer compared to the carriers with 8q24 rs13281615 AA genotype(OR=0.992, 95%CI: 0.660-1.490,P=0.968;OR=1.047, 95%CI: 0.642-1.708,P=0.853;OR=1.007, 95%CI: 0.682-1.487,P=0.971); Compared with A allele, G allele did not increase the risk of breast cancer(OR=1.021, 95%CI: 0.809-1.288,P=0.863).Conclusion:This experiment veriifed that 2q35 rs13387042 polymorphism site increased risk of breast cancer susceptibility among Han premenopausal women of Northern China. There was not any signiifcant association between 8q24 rs13281615 poly-morphism site and breast cancer susceptibility among Han premenopausal women of Northern China under the current sampling scale.

OBJECTIVETo observe the effect of Kanli Granule (KG) on myocardial mechanics in pressure overload induced diastolic heart failure (DHF) rats.

METHODSTotally 60 male Wistar rats were divided into the sham-operation group, the model group, the KG group, and the Valsartan group according to random digit table, 15 in each group. The pressure overload induced DHF model was established in all groups except the sham-operation group using abdominal aortic constriction surgery. Totally 7 rats died after modeling (with the mortality of 10. 67%) , and the rest 53 finished the following test. Rats in the KG group were administered with KG extract (calculated as 6. 75 g crude drug/kg) by gastrogavage. Rats in the Valsartan group were administered with Valsartan (7.2 µg/g) by gastrogavage. Equal volume of double distilled water was administered to rats in the model group and the sham-operation group by gastrogavage. All rats were intervened for 32 weeks. The response of isolated heart papillary muscle tonus to isoprenaline (ISO) and adenylate cyclase (Forskolin) was respectively observed. The enhancement phenomenon after resting development force (DF) of isolated heart papillary muscle tonus, and changes of DF in different Ca²⁺ concentrations were observed.

RESULTS(1) In the ISO response test: Compared with the sham-operation group, the amplifications of DF, ±df/dt, -df/dt were obviously elevated in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously lowered in the KG group (P < 0.01), and the amplification of ±df/dt was also reduced in the Valsartan group (P < 0.01). (2) In the Forskolin response test: Compared with the sham-operation group, the amplifications of DF and ±df/dt obviously increased in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously reduced in the KG group (P < 0.01), and the amplification of DF was also reduced in the Valsartan group (P < 0.05). (3) In post-resting DF enhancement test: Compared with the sham-operation group, the amplification of DF showed gradually decreasing tendency along with prolonged resting time in the model group, and they were obviously lowered at all time points (P < 0.05). Compared with the model group, the amplification of DF was gradually increasing along with prolonged resting time in the KG group. The amplification of DF at post-resting 240 s was obviously larger in the KG group than in the model group (P < 0.05). The amplification of post-resting DF still showed gradually decreasing tendency along with prolonged resting time in the Valsartan group, with increased amplifications of DF at post-resting 60 s and 120 s (P < 0. 05) (4) The amplifications of DF in different Ca²⁺ concentrations: Compared with the sham-operation group, the amplifications of DF were significantly elevated in different Ca²⁺ concentrations (1.75, 3.5, 7.0 mmol/L ) (P < 0.05, P < 0.01). Compared with the model group, there was no statistical difference in amplification of DF in different Ca²⁺ concentrations in the KG group (P > 0.05). The amplifications of DF in different Ca²⁺ concentrations were significantly reduced in the Valsartan group (P < 0.05).

CONCLUSIONSThe ISO response and the Forskolin response were enhanced in isolated heart papillary muscle tonus of pressure overload induced DHF rats; enhanced post-resting DF was reduced; DF in different supra-physiologic levels of Ca²⁺ was still enhanced. KG could significantly improve excessive enhancement of pressure overload induced DHF rats in ISO response and Forskolin response, and improve enhancement of post-resting myocardium.

By analysing the anatomy of upper cervical segment, the atlas - axis relation in plain X - ray film in 3-1 cases revealed that the joint displacement is one of the important causes for vertebral artery type or sympathetic type cervical spondylopathy. The main manifestations for diagnosing atlas - axis displacement included headache, dizziness, unilateral protrusion and tenderness of the affected vertebra, displacement of tooth protrusion up to 1 mm at anterior mouth -open positions. The most effective therapy was accurate and dexterousmanipulation for reduction.

ObjectiveTo compare the effect and prognosis of two kinds of internal fixation (improved Giebel blade plate and traditional straddle nail) after high tibial osteotomy (HTO) on osteoarthritis of knee with genu varus deformity. Methods37 knees of 32 cases were treated with straddle nail (25 knees) or Giebel blade plate (12 knees). All the cases were followed up for 6～28 months. ResultsThe clinical bone healing time of osteotomy was 8～12 weeks. There was no significant differences between 2 groups in the increased score in HSS Standard and in the clinical bone healing time. ConclusionBoth internal fixation with improved Giebel blade plate and traditional straddle nail get similarly satisfactory prognosis, while the former shows more advantages to allow early functional exercises.

OBJECTIVETo review the clinical features of the thoracolumbar fracture with ankylosing spondylitis (AS) in order to avoid delayed or missed diagnosis.

METHODSFive patients of thoracolumbar fracture with AS treated from April 2005 to June 2007 in our department were studied retrospectively, male 4 cases, female 1 case, the age from 26- to 72-years-old with an average of 44.8 years. Analysis including: case history, number of the ankylosed vertebras, characteristic of fracture, active state rheumatism.

RESULTSThe patients had the history of AS for average 22.6 years. The mean number of the ankylosed vertebras was 18.2. Of the 5 cases, 1 case encountered traffic accident, 1case was sprained, and 3 cases without trauma were diagnosed as stress fracture. Two cases were trans-vertebra fracture: the fracture line was through T6, T7, or L1 vertebral body respectively; 3 cases were through the disc space: 2 cases were through L1,2 disc space, 1 case was through L2,3. No compression fracture and neurological injury were found. The acute inflammatory index such as ESR and CRP in 4 cases didn't correlate with the degree of pain. The non-steroidal anti-inflammatory drugs (NSAIDs) hadn't significant effectiveness in relieving pain. The patients were diagnosed as 'relapse' of AS in other hospital, and had been misdiagnosed for average 1.51 months.

CONCLUSION1) the fracture is prevalent at the middle or late period of AS when extensive ankylosis has been existed at the thoracolumbar region; 2) the fracture is common at the lower thoracal spine and the upper lumbar spine, and the majority is the stress fracture; 3) the fracture line may be through the vertebral body, but more often through the disc space; 4) it is like an exacerbation of AS and therefore to be missed diagnosis; 5) when the back pain exacerbated suddenly in the middle or late period of AS, the degree of pain not correlating with acute inflammatory index, and the NSAIDs ineffective, the thoracolumbar fracture should be considered.
