Objective To investigate the metabolism characteristics and the potetial biomarker candidates of osteonecro?sis of the femoral head (ONFH) using metabolomic technology. Methods The femoral head specimens from 23 ONFH patients (25 necrotic femoral heads) and 18 normal femoral heads from femoral neck fracture patients were collected for histopathological examination to confirm the diagnosis of all samples. All the metabolites of bone trabecula were extracted for ultra-high perfor?mance liquid chromatography-MS/MS analyzed. The measured variables was pretreat, and PCA (principal component analysis), PLS?DA (partial least squares?discriminant analysis) and OPLS?DA (orthogonal?partial least squares?discriminant analysis) models were employed to confirm the difference between these two groups after UPLC?MS/MS (ultra?high performance liquid chromatogra?phy?mass spectrometry/mass spectrometry) analysis. At last, the differential variables were screened out by PLS?DA and variate analysis (Kruskal?Wallis H test). The changed metabolites were confirmed by MS and MS/MS aligned in HMDB (human metabolo?mic database) and Massbank. The changed metabolites with the most obviously changed peak abundance, D?arginine, L?proline and L?glutamine, were picked out as the potential diagnostic biomarkers. After binary logistic regression analysis, the combined biomarkers candidates were further analyzed by receiver operating characteristic (ROC) curve to evaluate the significance of the combined biomarkers. Results Significant distinction of metabolites expression mode can be seen in PCA, PLS?DA and OPLS?DA models scoring plots between ONFH and control groups. Twelve changed metabolites in ONFH bone trabeculas were con?firmed by multi?variate statistical analysis and variate statistical analysis. Compared with the femoral neck fracture patients, the in?creased metabolites included D?arginine, L?proline, L?glutamine, creatine, uracil, uridine, LysoPC(20∶4(5Z, 8Z, 11Z, 14Z)), Ly?soPC(16∶0), PC(20∶1(11Z)/18∶3(6Z, 9Z, 12Z)) and PE(P?16∶0e/0∶0). The decreased metabolites were reticulataxanthin and β?cryptoxanthin. According to the change fold of peak abundance and variable weight projection in PLS?DA, the most obviously dif? ferential metabolites were picked out as the biomarker candidates of ONFH. The potential biomarkers candidates were identified as D?arginine, L?proline and L?glutamine. The area under the curve of D?arginine, L?proline and L?glutamine ROC were 0.873, 0.712 and 0.862. The area under the curve of ROC was 0.946 after combining D?arginine, L?proline, L?glutamine using binary lo?gistic regression analysis. Conclusion PCA, PLS?DA and OPLS?DA models were used to find out the differential variables in the metabolites of bone trabeculas in ONFH and femoral neck fracture patients. Twelve metabolites were identified by MS/MS, and 3 obviously changed metabolites, D?arginine, L?proline, L?glutamine, were indicated as biomarker candidates. These 3 obviously changed metabolites showed a good diagnostic significance.

Objective To investigate the effects of hyperthyroidism on the electrophysiological characteristics of atrium and gap junction between atrium and pulmonary vein.Methods Twenty-four rabbits were randomly divided into control group and hyperthyroid group.Atrium and pulmonary vein were dissected after the atrial effective refractory period (AERP)was measured.Connexin 43(Cx43)and Counexin 40(Cx40)protein and mRNA were determined by Western blot and semi-quantitative reverse transcription-polymerase chain reaction,respectively.Results In comparison with control group,AERP and rate adaption of AERP in hyperthyroid group were significantly shorter than that of control group( P＜0.01).The concentration of Cx43 protein in hyperthyroid group was significantly higher than that of control group,but Cx40 protein was significantly lower than that of control group(P＜0.05).The expression of Cx43 mRNA in atrium and pulmonary vein was found to be up-regulated in hyperthyroid group as compared with that of control group(P＜0.01). With the level of Cx40 mRNA,there was no significant difference between two groups.Conclusion Thyroid hormone could lead to remodeling of both atrial electrophysiology and gap junction between atrium and pulmonary vein.

Objective To establish a method for rapidly detecting the G-protein ?3 subunit (GNB3) 825 site single nucleotide polymorphism (SNP) and to analyse the relationship between GNB3 825 site gene SNP and obesity. Methods The real-time fluorescent PCR was employed to analyse the GNB3 825 site gene SNP of 420 samples from 21 provinces and the the frequencies of genotypes were compared with those detected by gene sequencing. GNB3 825 site genotype, body weight, body mass index (BMI) and fat content were examined from 207 subjects and the correlation between GNB3 825 site gene SNP and obesity was analysed. Results The result by real-time fluorescent PCR showed that the frequencies of 825T and 825C haploid were 46.90% and 53.10%, respectively, and the frequencies of 825TT, 825TC and 825CC genotype were 22.38%, 51.42% and 28.10%, respectively, with no other genotype detected, which was consistent with the result by gene sequencing. BMI and fat content were significantly higher in subjects with GNB3 825TT than in subjects with other genotypes. Body weight was much higher in subjects with GNB3 825TT genotype than in subjects with 825CC genotype, but not significantly different with 825CT genotype. Conclusion A new rapid method for the detection of GNB3 825 site SNP has been successfully established. There existed significant correlation between GNB3 825TT genotype and obesity.

Objective To study the clinical and imaging characteristics of patients with infectious sacroiliac arthritis.Method Twenty-one patients diagnosed with infectious sacroiliac arthritis were analyzed retrospectively between 2000 and 2014.The chief complaint was pain in hip and lumbosacral area.Their clinical features,laboratory tests and pathological examination results as well as CT/MRI/PET-CT images were evaluated.Results There were nine males and thirteen females eighteen (85.7％) patients had unilateral sacroiliac joint involvement.Among these patients,three were diagnosed with brucellosis sacroiliac arthritis(BSI),eight patients with tuberculosis sacroiliac arthritis (TSI),and ten patients with non-brucellosis and non-tuberculosis infectious sacroiliac arthritis (ISI).For those patients with non-brucellosis and non-tuberculosis infectious sacroiliac arthritis,white blood cell count,erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)were dramatically increased.Twelve patients were diagnosed pathologically including 6 ISI,2 BSI and 4 TSI.Twelve patients and seventeen patients were scanned by CT and MRI respectively.Two patients undertook PET-CT examination.Antibiotic therapy showed significant therapeutic effects in all patients.Conclusion Infectious sacroiliac arthritis patients with hip or lumbosacral pain as the chief complaint can be easily misdiagnosed as spondyloarthritis.Comprehensive analysis of clinical features,imaging and laboratory findings is essential for accurate diagnosis.

Objective To compare the clinical efficacies of totally laparoscopic and laparoscopy-assisted radical total gastrectomies.Methods The retrospective cohort study was conducted.The clinicopathological data of 373 patients with gastric cancer who underwent totally laparoscopic or laparoscopy-assisted radical total gastrectomies from the 7 medical centers in China (82 patients in the Affiliated Hospital of Qinghai University,80 in the Traditional Chinese Medicine Hospital of Guangdong Province,60 in the First Affiliated Hospital of Xiamen University,51 in the Hangzhou First People's Hospital,46 in the First Affiliated Hospital of Xi'an Jiaotong University,30 in the Second Affiliated Hospital of Jilin University and 24 in the Xijing Hospital of the Fouth Military Medical University) between January 2015 and December 2016 were collected.Of 373 patients,the 183 and 190 patients were respectively divided into the totally laparoscopic group (undergoing totally laparoscopic radical total gastrectomy) and laparoscopy-assisted group (undergoing laparoscopy-assisted radical total gastrectomy),including 63 and 19 in the Affiliated Hospital of Qinghai University,36 and 44 in the Traditional Chinese Medicine Hospital of Guangdong Province,25 and 35 in the First Affiliated Hospital of Xiamen University,20 and 31 in the Hangzhou First People's Hospital,10 and 36 in the First Affiliated Hospital of Xi'an Jiaotong University,17 and 13 in the Second Affiliated Hospital of Jilin University,12 and 12 in the Xijing Hospital of the Fouth Military Medical University.Routine five-port method was applied for laparoscopic radical total gastrectomy and D2 lymphadenectomy.Roux-en-Y anastomosis was applied for digestive tract reconstruction,and digestive tract reconstruction was performed under laparoscopy in the totally laparoscopic group and via upper abdominal median incision in the laparoscopy-assisted group.Observation indicators:(1) operation and postoperative situations;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect the postoperative overall survival and tumor recurrence or metastasis up to March 2017.Measurement data with normal distribution were represented as x±s.Comparison between the groups was analyzed by the t test.Measurement data with skewed distribution were represented as M (range).Comparisons of count data were analyzed using the chi-square test and Fisher exact probability.Results (1)Operation and postoperative situations:all the patients in the 2 groups underwent successful operations,without perioperative death.Esophagojejunostomy methods of 183 patients in totally laparoscopic group:conventional circular stapler method were performed in 28 patients,anti-puncture circular staplar method in 6 patients,OrVilTM method in 5 patients,functional end-to-end esophagojejunostomy method in 65 patients and peristalsis side-to-side esophagojejunostomy method in 79 patients.Conventional circular stapler method was applied to 190 patients in the laparoscopy-assisted group.Operation time,time of esophagojejunostomy,length of assisted incision,using time of analgesics and expenses of digestive tract reconstruction were (238± 55)minutes,(29±9)minutes,(5.1 ± 1.1)cm,(2.2±l.0)days,(18 332±2 141)yuan in the totally laparoscopic group and (217±39)minutes,(26±7)minutes,(7.8 ±2.0)cm,(2.7± 0.9)days,(16 237 ± 1 923)yuan in the laparoscopy-assisted group,respectively,with statistically significant differences between the 2 groups (t =4.324,3.455,-16.835,-5.561,9.949,P＜0.05).The cases with postoperative overall complications,anastomosis leakage,anastomosis stricture,anastomosis bleeding and expenses of esophagojejunostomy were respectively 24,9,7,5,(9 668±2 814)yuan in the totally laparoscopic group and 24,8,9,6,(9 331 ±2 067)yuan in the laparoscopy-assisted group,with no statistically significant difference between the 2 groups (x2 =0.036,0.107,0.189,0.059,t=1.322,P＞0.05).All the patients with postoperative complications were cured by symptomatic treatment.(2) Follow-up and survival situations:of 373 patients,336 were followed up for 4-26 months,with a median time of 13 months,including 166 in the totally laparoscopic group and 170 in the laparoscopy-assisted group.During the follow-up,cases with overall survival,tumor recurrence and tunor metastasis were respectively 150,10,16 in the totally laparoscopic group and 154,9,16 in the laparoscopy-assisted group (10 and 9 patients in the totally laparoscopic and laparoscopy-assisted groups with simutaneous tumor recurrence and metastasis),showing no statistically significant difference between the 2 groups (x2 =0.075,0.010,P＞0.05).Conclusions Total laparoscopic and laparoscopyassisted radical total gastrectomies are safe and feasible,with equivalent overall outcomes and effects of esophagojejunostomy.Compared with laparoscopy-assisted radical total gastrectomy,the postoperative pain time of patients in total laparoscopic radical total gastrectomy is less,but there are longer time of esophagojejunostomy and higher expenses of digestive tract reconstruction.

Objective To investigate the immunological rejection in the brain of cloning goats received neural stem cell transplantation. Methods Eight cloning goats of CL series were chosen at random and divided into 2 groups. Neural stem cells and saline at the same dosages were transplanted into the fixed site by surgical intervention in the brain cortex of each group, respectively. The levels of IL-2 and IL-10 in the blood of each group were detected at different times (1 w before, and 0, 1 and 3 w,and 3 months after the cell transplantation) to reflect the systemic immune rejection of the goats after the transplatation. The CD3+ cells in the cell transplantation areas in each group were also detected by the method of immunohistochemistry to reflect the local immune rejection after the transplatation. Results The level of IL-2 was obviously higher and the level of IL-10 was obviously lower in the neural stem cell transplantation group than those in the control group 1 and 3 w, and 3 months after the cell transplantation (P＜0.05). The quantity of CD3+ cells in the neural stem cell transplantation group was much larger than that of control groups at the acute period (1 w after cell transplantation) and chronic period (3 months alter cell transplantation, P＜0.05). Conclusion Systemic and local immunological rejections at acute or chronic periods will appear at the brain of cloning goats with neural stem cells transplantation.
