Aberrant Expression of Cancer-Testis Antigen FBXO39 in Breast Cancer and its Clinical Significance.

BACKGROUND: Cancer/testis antigen (CTA) is a class of antigen molecules expressed only in the germinal epithelium of testis and some tumor tissues. As an important CTA molecule, the expression of F-box protein 39 (FBXO39) in breast cancer (BC) and its clinical significance remain unclear. The objective of this study is to explore the value of FBXO39 in the diagnosis, efficacy monitoring, and prognostic evaluation of BC. METHODS: The expression of FBXO39 mRNA in the serum exosomes of patients with BC before and after the initial diagnosis and treatment was detected by qRT-PCR, and the corresponding ROC curve was plotted. The expression of FBXO39 protein in BC cancer tissues was detected by immunohistochemistry, along with the analysis of the correlation between FBXO39 expression and clinical pathological features as well as prognosis of BC cases. RESULTS: The serum-derived exosomes were successfully isolated and identified. The positive rate of FBXO39 mRNA in serum exosomes of patients with BC was up to 86%; there was a correlation between the expression level of serum exosomal FBXO39 and clinical staging, HER2, and Ki-67 expression (all with p < 0.05). The sensitivity of serum exosomal FBXO39 in distinguishing BC patients from healthy controls was 88%, with the specificity as 86%, and AUC as 0.9432. The expression change of FBXO39 in serum-sourced exosomes of patients with BC was related to their treatment situation, indicating that the level of FBXO39 decreased significantly after treatment. The expression of FBXO39 in cancer tissue was related to the clinical stage (p = 0.023) and lymphatic metastasis (p = 0.015) of the BC patients. Survival analysis showed that the expression of FBXO39 was negatively correlated with the prognosis of BC patients, with the high expression of FBXO39 indicating poor prognosis. CONCLUSIONS: Serum-derived exosomal FBXO39 could serve as an important indicator of BC diagnosis and efficacy evaluation; FBXO39 could be rated as an important indicator of BC prognosis evaluation.

[Effect of breastfeeding versus formula milk feeding on preterm infants in the neonatal intensive care unit].

OBJECTIVE: To investigate the importance of breastfeeding in preterm infants with various gestational ages. METHODS: A total of 639 preterm infants with a gestational age of 28+3-36+6 weeks were enrolled, and according to the feeding pattern, they were divided into exclusive breastfeeding group (n=237) and formula milk feeding group (fed with liquid milk for preterm infants; n=402). These two feeding patterns were compared in terms of their effects on weight gain, laboratory markers including albumin (Alb) and alkaline phosphatase (ALP), incidence rate of feeding intolerance, and incidence rates of complications including necrotizing enterocolitis (NEC) and retinopathy of prematurity (ROP). RESULTS: Compared with the formula milk feeding group, the breastfeeding group had a significantly faster increase in body weight, a significantly lower incidence rate of NEC, a significantly higher ALP level, and a significantly lower Alb level in the preterm infants with a gestational age of 28-30 weeks (P<0.05); there were no significant differences between the two groups in the incidence rates of anemia, ROP, bronchopulmonary dysplasia (BPD), and nosocomial infection and length of hospital stay (P>0.05). For the preterm infants with a gestational age of 31-33 weeks, the breastfeeding group had a significantly faster increase in body weight, a significantly lower incidence rate of feeding intolerance, a significantly shorter length of hospital stay, and a significantly higher ALP level (P<0.05); there were no significant differences between the two groups in the incidence rates of NEC, anemia, ROP, BPD, and nosocomial infection and the Alb level (P>0.05). For the preterm infants with a gestational age of 34-36 weeks, there were no significant differences in these indices between the two groups (P>0.05). CONCLUSIONS: Breastfeeding plays an important role in increasing body weight, reducing the incidence rates of feeding intolerance and NEC, and shortening the length of hospital stay in preterm infants with a gestational age of 28-33 weeks.

[Value of abdominal ultrasound in the diagnosis of neonatal necrotizing enterocolitis and evaluation of disease severity].

OBJECTIVE: To investigate the value of abdominal ultrasound in diagnosing neonatal necrotizing enterocolitis (NEC) and its significance in evaluating the disease severity. METHODS: The clinical data of 84 neonates who were diagnosed with NEC between July 2013 and January 2015 were analyzed retrospectively. According to the modified Bell-NEC staging criteria, these neonates were divided into a suspected NEC group (n=44) and a confirmed NEC group (n=40); according to clinical prognosis, they were divided into a medical treatment and full recovery group (n=58) and a surgery/death group (n=26). The changes in the results of abdominal ultrasound and abdominal X-ray plain film were compared between groups. RESULTS: In the confirmed NEC group, abdominal ultrasound showed significantly higher detection rates of portal venous gas and dilatation of the intestine than abdominal X-ray plain film (P<0.05). Compared with the medical treatment and full recovery group, the surgery/death group had significantly higher detection rates of dilatation of intestine, bowel wall thickening, peritoneal effusion and free intraperitoneal air (P<0.05). Dilatation of the intestine and free intraperitoneal air shown by abdominal X-ray plain film were more common in the surgery/death group. CONCLUSIONS: Abdominal ultrasound is useful for the diagnosis of NEC. Ultrasonic findings can contribute to the prediction of the severity of NEC.

Determination and fingerprint analysis of steroidal saponins in roots of Liriope muscari (Decne.) L. H. Bailey by ultra high performance liquid chromatography coupled with ion trap time-of-flight mass spectrometry.

Liriope muscari (Decne.) L. H. Bailey is a well-known traditional Chinese medicine used for treating cough and insomnia. There are few reports on the quality evaluation of this herb partly because the major steroid saponins are not readily identified by UV detectors and are not easily isolated due to the existence of many similar isomers. In this study, a qualitative and quantitative method was developed to analyze the major components in L. muscari (Decne.) L. H. Bailey roots. Sixteen components were deduced and identified primarily by the information obtained from ultra high performance liquid chromatography with ion-trap time-of-flight mass spectrometry. The method demonstrated the desired specificity, linearity, stability, precision, and accuracy for simultaneous determination of 15 constituents (13 steroidal glycosides, 25(R)-ruscogenin, and pentylbenzoate) in 26 samples from different origins. The fingerprint was established, and the evaluation was achieved using similarity analysis and principal component analysis of 15 fingerprint peaks from 26 samples by ultra high performance liquid chromatography. The results from similarity analysis were consistent with those of principal component analysis. All results suggest that the established method could be applied effectively to the determination of multi-ingredients and fingerprint analysis of steroid saponins for quality assessment and control of L. muscari (Decne.) L. H. Bailey.

A new automatic stitching method for full-length lower limb radiography.

Full-length lower limb x-rays are used to diagnose and plan surgical procedures, such as Total Knee Arthroplasty (TKA) and High Tibial Osteotomy (HTO). Due to the size limitation of digital radiography (DR), panoramic x-ray images cannot be obtained in a single exposure, necessitating multiple exposures and image stitching. In favor of manually constructing full-length x-ray images, we propose a new feature-based automated method for stitching together x-ray images. This new method is based on Canny algorithm, which detects and aligns bone edges before fusing them using a Wavelet form domain. Twenty-eight sets of lower limb x-ray images obtained from our hospital have been stitched and evaluated. The hip, knee, and ankle (HKA) angle was computed in two different ways then compared to manually stitched x-ray images by an expert. The stitching time was only three seconds, and the P-value was P = 0.974, and an accuracy rate of 100% was found. This method demonstrated greater precision and speed than both manually stitched x-ray images and previously published methods.

The susceptibility to vitiligo is associated with NF-E2-related factor2 (Nrf2) gene polymorphisms: a study on Chinese Han population.

Vitiligo is an acquired pigmentary disorder and its pathogenesis remains unclear. Oxidative stress is considered to be the initial pathogenic event in the melanocyte destruction. NF-E2-related factor2 (Nrf2) is a transcription factor regulating the expression of detoxifying and antioxidant genes. To investigate the association of the Nrf2 gene promoter polymorphisms with vitiligo in Chinese Han population, the genotypes of -686A/G, -684G/A and -650C/A and the genotyping of variable number of tandem repeat were detected. The data were analysed by the chi-square test and the risk was evaluated by calculating OR and 95% CI. There was statistically significant difference in genotypic and allelic frequencies of -650C/A between the two groups (P < 0.05). A(-650) allele was significantly associated with the risk for vitiligo (OR = 1.724, chi(2) = 18.096). Polymorphism of the Nrf2 gene promoter at -650C/A was associated with the development of vitiligo and A(-650) allele may be one of the risk factors.

[Association of single nucleotide polymorphisms of Nrf2 promoter region with susceptibility to vitiligo].

OBJECTIVE: To investigate the association of the single nucleotide polymorphisms (SNPs) in Nrf2 promoter region with the susceptibility to risk of vitiligo. METHODS: Samples of peripheral blood were collected from 300 vitiligo patients and 300 healthy persons. The genotypes of -686A/G, -684G/A, and -650C/A were detected by direct-sequencing. Genotyping of variable number of tandem repeat (VNTR) was performed by gene scan analysis with an ABI 310 Sequencer. Genetic and allelic frequencies were analyzed by Chi-square test and the risk was evaluated by calculating OR and 95% CI. RESULTS: There was statistical significant difference in genotypic and allelic frequencies of -650C/A between the vitiligo group and healthy control group (P < 0.05), and A -650 allele was associated with risk for vitiligo statistically significantly (OR = 1.724, 95% CI: 1.345-2.211, chi2 = 18.096, P < 0.01). Homozygote of A allele increased the risk for vitiligo obviously (OR = 2.902, 95% CI: 1.624-5.188, P < 0.01). No significant difference was found in other three polymorphisms between the two groups. CONCLUSION: polymorphism of Nrf2 promoter region -650C/A was associated with the development of vitiligo and A -650 allele may be one of risk factors for vitiligo.

[Effects of glycyrrhizin on the expression of hepatitis B virus and Toll like receptors 2,4 in HepG2.2.15 cells expressing low HBsAg].

OBJECTIVE: To investigate the effects of glycyrrhizin (GL) on the expression of hepatitis B virus e antigen (HBeAg), HBV DNA, Toll-like receptors 2,4 (TLR2,4) and proliferation of cells in HepG2.2.15 cell line. METHODS: Real-time PCR examined HBV DNA, ELISA examined HBsAg, HBeAg and MTT examined the proliferation of cells. FCM examined the positive percent of cells expressing TLR2,4 before and after stimulated with GL, in contrast to the blank group. RESULTS: The expression of HBsAg was low in the cell line, so e antigen was studied. The total HBeAg mean was significantly difference on the second day after stimulated (P<0.01), but only in the group with 400 microg/ml HBeAg decreased significantly in contrast to the blank group (P<0.05), the group with 800 microg/ml increased significantly in contrast to the other groups (P<0.01). The total HBV DNA mean on the third day after stimulated was significant, only the group with 50 microg/ml decreased in contrast to the blank group, but P>0.05, the other four groups increased. The intensity of TLR4 expression in the cells was significantly higher than that of the control group (P<0.05), both of total mean TLR2,4 increased significantly (P<0.01). The four groups except the group with 200 microg/ml increased significantly in no dose-dependent manner (P<0.05). GL in three goups under 200 microg/ml all could make cells proliferate, but only 200 microg/ml group had significant difference compared to the blank group (P<0.05). Both 400 and 800 microg/ml groups inhibited the growth of cells (P<0.01). The proliferation of cells were notably negative correlated with the expression of HBeAg, HBV DNA (P<0.05). CONCLUSION: The study suggestes GL could inhibit or promote HBV DNA replicating and e antigen secreting in mutative HepG2.2.15 cell line, the correlation between the proliferation of cells and the both are negative. GL could upregulate TLR2,4 in no dose-dependent manner. Influencing HBV maybe have no correlation to up regulating TLR2,4 by GL at least in vitro.

Feasibility study of a human papillomavirus E6 and E7 oncoprotein test for the diagnosis of cervical precancer and cancer.

Objective To evaluate the clinical value of human papillomavirus (HPV) E6 and E7 oncoprotein (HPV E6/E7) detection in the early screening of cervical cancer. Methods This prospective study evaluated all patients with suspected cervical intraepithelial neoplasia (CIN) as identified by the presence of at least one positive indicator from a ThinPrep cytologic test (TCT) and/or a Hybrid Capture 2 (HC2) HPV DNA test. The levels of E6/E7 oncoproteins were determined using Western blot analysis. The diagnostic value of the HPV E6/E7 protein assay was compared with the clinical diagnosis from TCT, HC2 and the gold standard of cervical biopsy histology. Results A total of 450 patients were enrolled in the study and based on histological findings, 102 patients were diagnosed with CIN1 (22.7%), 241 with CIN2 (53.6%), 96 with CIN3 (21.3%) and 11 with squamous cell carcinoma (2.4%). For a diagnosis of CIN2+, although the sensitivity of the HPV E6/E7 assay was lower than HC2 (65.5% versus 96.6%, respectively), the specificity was higher (38.2% versus 5.9%, respectively). The sensitivity of the HPV E6/E7 assay was higher than TCT (65.5% versus 36.2%, respectively). Conclusion Measuring HPV E6/E7 oncoprotein levels is a potential new biomarker for HPV type 16.

Catechol-O-methyltransferase 158G/A polymorphism and endometriosis/adenomyosis susceptibility: A meta-analysis in the Chinese population.

PURPOSE: An association between catechol-O-methyltransferase (COMT) 158G/A polymorphism and endometriosis/adenomyosis susceptibility has been reported in the previous studies, but the results were inconsistent. This study was conducted to explore this association in the Chinese population using meta-analysis. MATERIALS AND METHODS: PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure, and Chinese Biology Medicine were searched for all relevant studies published up to December 2015. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to estimate the strength of the associations. RESULTS: A total of 7 case-control studies including 782 cases and 700 controls were included in this meta-analysis. Overall, COMT 158G/A polymorphism was found to be significantly associated with endometriosis and adenomyosis risk in the Chinese population (A vs. G, OR = 1.21, 95% CI: 1.02-1.42; AA vs. GG, OR = 1.47, 95% CI: 1.01-2.14; AA vs. GG + GA, OR = 1.42, 95% CI: 0.99-2.03; AA + GA vs. GG, OR = 1.20, 95% CI: 0.97-1.49). In subgroup analyses stratified by ethnicity, source of controls and disease groups, the significant risk was found in Chinese not mentioned the ethnicity, in population-based studies and adenomyosis. CONCLUSIONS: COMT 158G/A polymorphism may contribute to the risk of endometriosis and adenomyosis in Chinese, particularly for adenomyosis.

[Expression and purification of epitope peptide of human tyrosinase and its antigenicity in vitiligo patients].

OBJECTIVE: To express the epitope peptide of human tyrosinase (TYR), and discuss the application of the peptide in detecting autoantibody of the vitiligo patients. METHODS: The epitope areas 240 - 255, 289 - 294, 295 - 300, 435 - 447, and 461 - 479 of human TYR were synthesized and connected to the vector pGEM-T. The target gene was cloned to the prokaryotic expression vector pGEX-4T-2, which was then transferred to Escherichia coli BL21 host cells. Isopropy-beta-D-thiogalactoside (IPTG) was used to induce the protein expression that was examined with SDS-PAGE and Western blotting. Indirect ELISA was conducted to detect the antigenicity of the peptide in 100 blood specimens of active vitiligo patients and 30 healthy controls. RESULTS: The recombinant expression vector was constructed successfully. The SDS-PAGE and Western blotting results showed expression of the recombinant protein in E. coli. The amount of the recombinant protein reached about 70% of the total mass of bacterial protein with PAGE analysis system. With the glutathione S-transferase (GST) purification kit, the purity of recombinant protein reached over 90%. Indirect ELISA showed that reaction with the target protein was negative in all the 30 healthy controls and was positive in 64 of the 100 active vitiligo patients. CONCLUSION: The epitope peptide of human TRY is expressed successfully, and it has antigenicity in the serum of vitiligo patients.

[The clinical study on decompensatory cirrhotic patients treated by Bie Jia Jian].

OBJECTIVE: To observe the clinical curative effect on decompensatory cirrhotic patients treated by Bie Jia Jian. METHODS: 98 decompensatory cirrhotic patients were randomly divided into two groups: 49 patients in treatment group and 49 in control group. Both groups were treated with the same western medicine of protecting and supporting liver. Except that, treatment group were treated by Bie Jia Jian. RESULTS: The Contents of AST, ALT, total bilirubin (TB), direct bilirubin (DB), hyaluronic acid (HA), Laminin (LN) , procollagen III (pc III), and type IV collagen (IV.C) in both groups decreased after treatment, and prothrombin time activity (PTA) increased. Among them, the decrease of TB, DB, HA, LN, PC-III and IV-C, and the increase of PTA in treatment group were more obvious than those in control group (P < 0. 05). CONCLUSION: Bie Jia Jian is effective in treating decompesatory cirrhotic patients.

Silencing of Armadillo Repeat-Containing Protein 8 (ARMc8) Inhibits TGF-ß-Induced EMT in Bladder Carcinoma UMUC3 Cells.

Armadillo repeat-containing protein 8 (ARMc8) is a key factor in regulating cell migration, proliferation, tissue maintenance, and tumorigenesis. However, its role in bladder cancer remains unknown. Thus, in this study we sought to investigate the effect of ARMc8 on the epithelial-to-mesenchymal transition (EMT) progress in bladder cancer cells induced by transforming growth factor-ß1 (TGF-ß1). Our results found that ARMc8 was highly expressed in bladder cancer cell lines. ARMc8 silencing inhibited the TGF-ß1-induced migration and invasion and suppressed the EMT progress in bladder cancer cells. Furthermore, ARMc8 silencing inhibited the TGF-ß1-induced expression of ß-catenin, cyclin D1, and c-myc in bladder cancer cells. In conclusion, the present study demonstrates a novel function for ARMc8, which acts as a mediator for TGF-ß1-induced cell migration/invasion through modulation of the Wnt/ß-catenin signaling pathway in bladder cancer cells. This study suggests that ARMc8 may be a potential therapeutic target for the development of therapies for bladder cancer.

Upper gastrointestinal cancer burden in Hebei Province, China: A population-based study.

AIM: To investigate the incidence and mortality rates of upper gastrointestinal cancer (UGIC) in Hebei Province, China, and to identify high-risk populations to improve UGIC prevention and control. METHODS: Data for UGIC patients were collected from 21 population-based cancer registries covering 15.25% of the population in Hebei Province. Mortality data were extracted from three national retrospective death surveys (1973-1975, 1990-1992 and 2004-2005). The data were stratified by 5-year age groups, gender and area (high-risk/non-high-risk areas) for analysis. The age-period-cohort and grey system model were used. RESULTS: The crude incidence rate of UGIC was 55.47/100000, and the adjusted rate (Segi's population) was 44.90/100000. Males in rural areas had the highest incidence rate (world age-standardized rate = 87.89/100000). The crude mortality rate of UGIC displayed a decreasing trend in Hebei Province from the 1970s to 2013, and the adjusted rate decreased by 43.81% from the 1970s (58.07/100000) to 2013 (32.63/100000). The mortality rate declined more significantly in the high-risk areas (57.26%) than in the non-high-risk areas (55.02%) from the 1970s to 2013. The median age at diagnosis of UGIC was 65.06 years in 2013. There was a notable delay in the median age at death from the 1970s (66.15 years) to 2013 (70.39 years), especially in the high-risk areas. In Cixian, the total trend of the cohort effect declined, and people aged 65-69 years were a population at relatively high risk for UGIC. We predicted that the crude mortality rates of UGIC in Cixian and Shexian would decrease to 98.80 and 133.99 per 100000 in 2018, respectively. CONCLUSION: UGIC was the major cause of cancer death in Hebei Province, and males in rural areas were a high-risk population. We should strengthen early detection and treatment of UGIC in this population.

[The clinical and pathological characteristics of histiocytic necrotizing lymphadenitis: analysis of 52 cases].

OBJECTIVE: To study the clinical manifestation and pathological features of histiocytic necrotizing lymphadenitis (Kikuchi's disease, KD). METHODS: 52 patients with KD were collected to analyze the clinical manifestation, pathological features of biopsy lymph nodes, diagnosis and treatment. RESULTS: 41 cases (79%) were female of the 52 patients. The main clinical features included persistent fever (100%), single (23%)/multi (77%)-lymphadenopathy (always in cervical region), pleomorphism erythra (35%), neutropenia (76%), elevated erythrocyte sedimentation rate (100%), insensitivity to antibiotics (100%) and sensitivity to small dosage glucocorticoid (81%). 26 cases (50%) had elevated aspartate aminotransferase and/or alanine aminotransferase, but only 7 cases (13%) had upper respiratory tract symptom like influenza. Pathological features included distinctive necrosis, loss of lymph node structure, infiltration with histiocytes and lymphocytes, absence of neutrophils. Immunohistochemical stainings showed CD(68) positive for histiocytes and CD(3), CD(45) RO positive for T lymphocytes. CONCLUSION: Diagnosis of KD relies on the pathological examination and immunohistochemical staining.

[Study on the social factors of patients with genital herpes relapsing].

OBJECTIVE: To investigate the social factors of patients with genital herpes (GH) relapsing and guide GH patients to avoid the related social factors. METHODS: To select 96 case of patients with recurrent genital herpes of final diagnosis and detailedly record the related social factors before relapsing. The social factors were compared between male and female GH patients, and compared between frequently recurrent (> 6/year) and non-frequently recurrent GH patients (< or = 6/year) too. RESULTS: 65.6% (63/96) of recurrent GH patients have certain social factors before relapsing. The main social factors are overtiredness, mental stress and excessive sexual contact. Staying up late and excessive drinking are common social factors, too. There was no significant difference of social factors between male and female GH patients (P >. 05), and also no significant difference between frequently recurrent and non-frequently recurrent GH patients (P > 0.05), too. CONCLUSION: Overtiredness, mental stress and excessive sexual are the main social elements during inducing genital herpes relapsing. It is important to reduce GH relapsing and spreading of HIV and syphilis by guiding recurrent genital herpes patients to avoid related social elements.

Hepatocellular carcinoma and hepatitis B surface protein.

The tumorigenesis of hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) has been widely studied. HBV envelope proteins are important for the structure and life cycle of HBV, and these proteins are useful for judging the natural disease course and guiding treatment. Truncated and mutated preS/S are produced by integrated viral sequences that are defective for replication. The preS/S mutants are considered "precursor lesions" of HCC. Different preS/S mutants induce various mechanisms of tumorigenesis, such as transactivation of transcription factors and an immune inflammatory response, thereby contributing to HCC. The preS2 mutants and type II "Ground Glass" hepatocytes represent novel biomarkers of HBV-associated HCC. The preS mutants may induce the unfolded protein response and endoplasmic reticulum stress-dependent and stress-independent pathways. Treatments to inhibit hepatitis B surface antigen (HBsAg) and damage secondary to HBsAg or the preS/S mutants include antivirals and antioxidants, such as silymarin, resveratrol, and glycyrrhizin acid. Methods for the prevention and treatment of HCC should be comprehensive.

Association between IL-6 Gene (-174 & -572 G/C) Polymorphisms and Endometrial Adenocarcinoma Risk.

We aimed to evaluate the association of IL-6 gene polymorphisms at positions of -174 and -572 and predisposition of endometrial adenocarcinoma (EAC) in a Chinese population. EAC patients have remarkably higher frequency of IL-6 -174 CC genotype [odds ratio (OR) =1.56, 95 % confidence interval (CI) =1.07-2.23; P = 0.03], IL-6 -572 CC genotype (OR =1.93, 95%CI =1.17-3.15; P = 0.01) and IL-6 -174 C allele (OR =1.22, 95 % CI =1.03-1.46; P = 0.04) compared with healthy controls. When stratified with FIGO stage, patients with III-IV EAC have a significantly higher frequency of IL-6 -174 CC genotype (OR =1.66, 95% CI =1.06-2.58; P = 0.02) than healthy controls. The CC genotype of IL-6 gene polymorphisms at positions of -174 and -572 may denote potential high risk of EAC.

[Analysis of clinical characteristics of 20 patients with pyogenic spondylitis].

OBJECTIVE: To investigate the diagnostic value of clinical manifestation, laboratory examination and imaging changes for pyogenic spondylitis and to summarize the clinical characteristics of patients with pyogenic spondylitis. METHODS: The clinical data, of 20 patients with pyogenic spondylitis were diagnosed by histopathological examination from March 2012 to March 2015, were retrospectively analyzed. There were 9 males and 11 females, aged from 43 to 72 years old with an average of 58.9 years. Included 3 cases of cervical vertebrae, 7 cases of thoracic vertebrae, 10 cases of lumbar vertebrae. Patients of blood analysis, erythrocyte sedimentation rate(ESR), C reactive protein(CRP), X rays, CT and MRI were performed before treatment. Visual analogue scale (VAS) was used to evaluate the pain of patients suffering from vertebral pain. RESULTS: All the patients had suffered from vertebral pain before treatment. VAS was 9 points in 4 cases, 8 points in 6 cases, 7 points in 1 case, 3 points in 6 cases, and 2 points in 3 cases. Among them, 7 patients complicated with neurological symptoms, 11 with aggravating night pain, 10 with fever. WBC and Neutrophil count (NEU) of 5 cases were increased and other 15 cases were normal;CRP of 19 cases were increased and 1 case was normal;ESR of all 20 cases were increased. X rays showed the intervertebral space narrowing in all 20 cases, 13 cases complicated with destruction of vertebral body; CT showed the lesions of vertebral body in the 20 cases and complicated with destruction, sclerosis of sclerotin; MRI showed that the lesions of the vertebral body in the T1 image had uneven medium low signal, in the T2 image of the 16 cases had uneven high signal and 2 cases had uniform and high signal, 2 cases had main high signal compliated with mixed signal. Thirteen patients underwent surgical treatment and 7 patients received conservative treatment, and the patients left hospital while VAS had significantly improved after treatment. CONCLUSIONS: Pyogenic spondylitis is easy to be misdiagnosed or missed in clinic. It can be combined with the clinical manifestations, laboratory examination and imaging characteristics in order to make a definite diagnosis for purulent spondylitis in early.
