ObjectiveTo investigate the value of “streaks” sign in diagnosis of central neurocytoma.MethodsFifty-two cases of central neurocytoma confirmed by pathology from 2008 to 2011 were collected.In 52 cases,both MRI and CT scan were performed on 12 patients,MRI only on 36 patients and CT only on 4 patients.MRI and CT features were analyzed retrospectively.ResultsIn MRI,the “streaks” sign was found in 39 cases,accounting for 81.25％(39/48).In CT,the“streaks” sign was found in 11 patients,accounting for 68.75％(11/16).The “streaks” sign in CTwas also found in MRI.ConclusionsThere is a certain specificity of“streaks” sign in central neurocytoma imaging.In combination with other imaging findings,it can be helpful for an accurate preoperative diagnosis of the disease.

OBJECTIVE: To study the correlation between age and general morphology of transverse section of cartilago costalis and its forensic significance. METHODS: Eighty-six corpses' cartilago costalis from the routine postmortem examination were collected and the morphological features of their transverse section were observed. RESULTS: With the increased age, there were regular changes in the color, structure, and material of the general morphology of transverse section of cartilago costalis. But the changes were not affected by gender. CONCLUSION The good correlation between general morphology of transverse section of cartilago costalis and age can be used to estimate age of the deceased rapidly.

OBJECTIVETo study the syndrome of inappropriate ADH secretion (SIADH) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the possible etiology.

METHODSThe clinical manifestation, laboratory examination, treatment and outcome of a patient with refractory anemia with excess blasts after allo-HSCT were presented.

RESULTSHyperacute graft-versus-host disease (GVHD) was developed in the patient after allo-HSCT followed by severe hyponatraemia (lowest serum sodium 103.7 mmol/L), natriuresis, hypo-osmolality of plasma, hyper-osmolality of urine, coma and twitch at day 17 after allo-HSCT. SIADH was diagnosed. The clinical condition was improved after restriction of water and administration of hypertonic saline, but SIADH was not controlled completely. Afterwards, graft failure was developed. Hyperacute GVHD and graft rejection occurred again after the second transplant. The patient died of secondary infection.

CONCLUSIONSIADH after allo-HSCT is a rare fatal acute complication of central nervous system. Numerous transplant-related causes are probably associated with the development of SIADH. Early accurate diagnosis and treatment promptly is of great importance.

OBJECTIVETo evaluate the functional outcomes of modified limited "L" incision beside the Achilles tendon with distraction bone block arthrodesis in treatment of subtalar osteoarthritis.

METHODSFrom March 2009 to September 2012, a total of 22 cases of old calcaneus fractures with subtalar osteoarthritis were treated with modified limited "L" incision and distraction bone block arthrodesis including 13 males and 9 females with a mean age of 35.3 years old (ranged 22 to 49). The mean time from calcaneal fracture was 21 months (ranged 11 to 32). According to the Stephens-Sanders classification, 16 cases were type II and 6 were type III. The modified-AOFAS ankle-hindfoot score was used for functional outcomes evaluation.

RESULTSThere was one incision necrosis and no infection, implant failure, bone-graft absorbed or talus necrosis was note at the follow-up time. A total of 21 cases were followed up for a mean time of 29 months (ranged from 18 to 46 months). All of the cases reached a bony union within 4 months postoperation. The mean modified-AOFAS ankle-hindfoot score was 82.6 points (ranged from 66 to 92 points),reached a significantly improvement in comparing with the mean preoperative score (50.8 points,ranged from 32 to 65 points, P < 0.01).

CONCLUSIONThe modified limited"L" incision beside the Achilles tendon with distraction bone block arthrodesis is an acceptable and alternative treatment method for subtalar osteoarthritis. This method is easy to use and with less complication. It can correct the main pathological changes and reach good functional outcomes.

ObjectiveThe mechanism that affects the infiltration of immune cells in pancreatic cancer has not yet been clarified. This study aims to investigate the lncRNA mRNA regulatory pathways that affect immune infiltration in pancreatic cancer.MethodsTCGA and GEO gene expression data were used to screen common differential lncRNAs. We perform survival analysis, target gene prediction, GO, KEGG enrichment analysis, immune infiltration analysis, gene set enrichment analysis (GSEA) on the selected differential lncRNAs to identify the relevant pathways of immune infiltration.ResultsThe pancreatic cancer patients with high expression of ADAMTS9 AS1 have a higher survival rate when compared to patients with low expression (P=0.010). The combined analysis of TCGA and GSE86436 revealed the difference and survival-related ADAMTS9 AS1. The functional prediction of ADAMTS9 AS1 was related to immunity. Using the TIMER database, the lncRNA affected the infiltration of immune cells in pancreatic cancer tissues. The clinical analysis was demonstrated that the ADAMTS9 AS1 was related to pathological grade. The target gene SEMA3G was screened by co-expression analysis using the IMMPORT database and TIMER database. Lastly, GSEA analysis of ADAMTS9-AS1 showed that the lncRNA was also related to tumor metabolism.ConclusionThese results indicate that ADAMTS9-AS1-SEMA3G is associated with the prognosis and immune invasion level of pancreatic cancer, which can provide a theoretical basis for subsequent genetic verification experiments and immune research.

OBJECTIVETo establish a microemulsion liquid chromatography system with direct sample loading for determining the serum level of emodin in rats.

METHODSThe separation was performed on C₁₈ column (Hypersil BDS, 5 µm,150 mm×4.6 mm) with the microemulsion mobile phase consisting of 3.3% (w/V) SDS, 6.6% (V/V) n-butyl alcohol, and 1.0% (V/V) octane and water. The flow rate was 1.0 ml/min and the detection wavelength was 254 nm.

RESULTSThe linear range of emodin detection was 0.333-5.32 µg/ml. The average recovery was 99.65% with a RSD of 3.60%. The limit of quantification was 0.1386 µg/mL.

CONCLUSIONMicroemulsion liquid chromatography system with direct sample loading allows simple, accurate and rapid determination of emodin in rat serum.

OBJECTIVETo explore the associations between fasting serum lipids and high-sensitivity C-reactive protein (hsCRP).

METHODSSerum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and hsCRP were measured in residents of Chengdu, China. Subjects with potential factors which might influence lipids and hsCRP were excluded, 580 subjects [mean age (62.3 ± 6.6) years; male: 58.7%] were finally recruited by random sampling methods.

RESULTSThere was a weak positive relationship between TG and hsCRP (r = 0.108, P = 0.01) and a weak negative relationship between HDL-C and hsCRP (r = -0.197, P < 0.001), this was also true in the sub-group with BMI < 24 kg/m(2) (r = 0.236, -0.140 respectively, all P < 0.001). In subjects with BMI < 24 kg/m(2), the hsCRP concentration was significantly higher in subjects with higher TG or lower HDL-C (all P < 0.05). hsCRP increased in proportion with the degree of dyslipidemia. After adjusting for gender, age, TC, LDL-C, fasting blood glucose, systolic blood pressure, diastolic blood pressure, history of hypertension and diabetes, smoking and alcohol drinking, logistic regression analysis showed that the odds ratio for increased hsCRP was 1.970 in subjects with either increased TG or lower HDL-C (P = 0.105) and 9.098 in subjects with both higher TG or lower HDL-C levels (P = 0.031). However, the observed relationship between TG, HDL-C and hsCRP in subjects with BMI < 24 kg/m(2) could not be observed in subjects with subjects with BMI > 24 kg/m(2) despite significant more cardiovascular risk factors in these subjects.

CONCLUSIONSA weak positive correlation between TG and hsCRP as well as a weak negative correlation between HDL-C and hsCRP was evidenced in the whole cohort suggesting dyslipidemia might be related to enhanced inflammatory status. However, this relationship is not observed in subjects with BMI > 24 kg/m(2) despite existence of more cardiovascular risk factors in these subjects.
