Objective:To evaluate the relationship between MRI features and pathological types of intracranial meningomas.Methods:32 cases of meningoma which were proved by operation and pathology were compared with their MRI features and pathological types.Results:All of the 32 cases were single tumor,The lesions were located in frontal,parietal,and occipital regions nearby the convexity of the brain in 18 cases,at sphenoidal crest in 8 cases,at olfactory sulcus in 4 cases,and in sellar region 2 cases.MRI manifested that 13 cases had their intergral capsules,peri-tumor edema was found in 29 cases,dural“tail” sign was present in 9 cases,calcification in the tumors were found in 3 cases and vascular flow void features was seen in 5 cases,20 cases appeared homogeneous enhancement.Conclusion:It is of great value in presenting the location of meningoma with MRI.Combination of several MRI features could be used to figure out the pathological type of meningoma by a comprehensive analysis.

Objective To explore the tumor markers for the diagnosis of primary liver carcinomas (PLC) by detecting the serum protein spectrum differently expressed between PLC patients and healthy controls. Methods We detected the serum protein spectrum in 50 PLC patients and 50 healthy controls using surface enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF-MS) technique and find the significant protein peaks. The serum Alpha-fetoprotein (AFP) levels in all 100 serum samples were also measured by ELISA. Results The protein peaks, which could discriminate healthy individuals from PLC patients, were detected. Four protein molecules (3354.71, 8825.80, 4345.08, 13 715.01) had a significant difference between PLC patients and the normal controls (P <10-5), indicating that these protein molecules might be a potential marker for PLC. The specificity and sensitivity of SELDI-TOF-MS were 94% and 90% respectively. Sixteen PLC patients were AFP positive and the sensitivity was 54%(27/50). Conclusion With a high specificity and sensitivity, the detection of serum protein spectrum can be performed easily and quickly by SELDI-TOF-MS technique, which provides a serological way in identifying PLC and most likely to benefit from AFP strategies.

Objective:To determine the effects of Jinlong capsule combined with interventional therapy on the immune functions of primary hepatocellular carcinoma patients. Methods:Sixty randomly selected cases of clinically diagnosed primary hepatocellular carcinoma were divided into the observation group and the control group. Three days after operation, the observation group was given four Jinlong capsules three times a day for 30 days (one treatment). Meanwhile, the control group received interventional therapy after the operation. One to four days following one treatment, peripheral blood specimens were collected from the two groups to determine the cellular immune function indices. Results:The cell numbers (mean) of the peripheral blood components CD3, CD4, NK, SIL-2R, TSGF, and SIL-2R and the CD4/CD8 ratio in the observation group showed no significant difference before and after treatment. In the control group, these indices were significantly different before and after treatment. Conclusion:The Jinlong capsule facilitates the cellu-lar immunity recovery of patients with primary hepatocellular carcinoma after interventional therapy.

Objective To screen Oxalobacter formigenes (OxF) from fresh feces of healthy adults,and study its effect on the the prevention of calcium oxalate kidney stones.Methods OxF was screened and cultured from fresh feces of healthy adults.The rat model of calcium oxalate stone was established by esophageal gavage of 0.8％ of ethylene glycol.Rats were divided into a control group and four groups of rats with ethylene glycol-induced calcium oxalate kidney stones according to random number table.Three groups were treated with 106 CFU,107 CFU,108 CFU viable OxF every day,respectively,for 4 weeks.The blood and 24-hour urine samples were collected to detect the serum creatinine,urea nitrogen,serum and urine calcium,phosphorus,magnesium and urine oxalate every week.At the end of the 4th week,the rats were sacrificed and the kidney tissues were stained with HE and Yasue.The deposition and content of calcium oxalate crystals were observed under a light microscope.Results The bacteria strain isolated from fresh feces of healthy adults was 100％ as same as the known ATCC35274 bacteria strain,which means the strain screened is OxF.Among the 5 groups,there were no significant differences in body weight,Scr,BUN,serum calcium,blood magnesium,blood phosphorus,urinary magnesium and urinary phosphorus.The 24-hour urinary calcium excretion in the model group was significantly lower than that of the control group (P ＜ 0.05).After intervention with OxF solution,the 24-hour urinary calcium excretion in the 108 CFU OxF group was significantly higher than that in the model group (P ＜ 0.05),while there was no significant difference between the other intervention groups and the model.The oxalic acid excretion of 106 CFU OxF group and 107 CFU OxF group was lower than that of the model,but the difference did not reach statistical significance (P＞ 0.05).The 24 h oxalic acid excretion in the 108 CFU OxF group was significantly lower than that of the model at the end of first week (P ＜ 0.05),and continued to decrease for the next 3 weeks.After 4 weeks of intervention,no crystal formation was observed in the control group under the deflection microscope,but a large amount of calcium oxalate crystals were formed in the renal cortex and renal medulla.The crystals were piled up and connected to each other.Yasue staining coincided with the calcium oxalate crystal in the same part of the kidneys.Compared with the model,there was no significant change in the score of calcium oxalate crystal in the kidneys of 106 CFU OxF group and 107 CFU OxF group,while the score of calcium oxalate crystal in the kidneys of 108 CFU OxF group was significantly lower (P ＜ 0.05).Conclusions OxF are successively screened from healthy adults.Daily administration of 108 CFU OxF can safely and effectively reduce the urinary oxalic acid excretion,prevent the formation of calcium oxalate crystals and inhibit the formation of stones in kidneys of rats.

Objective:To determine the correlations of single nucleotide polymorphisms (SNPs) with atrial fibrillation (AF) in the Chinese Han population from the central plains.Methods:A total of 168 hospitalized patients,including 56 AF and 112 controls,were recruited in this case-control study.The clinical data were obtained from the medical records.All 5 SNPs,rs337711 in KCNN2,rs11264280 near KCNN3,rs17042171 near PITX2,rs6771157 and rs6795970 in SCN10A,were genotyped using amplification refractory mutation system-polymerase chain reaction or direct sequencing.The x2 test was used to compare categorical variables and preliminarily examine correlations between the genotype frequencies and AF.Subsequently,a logistic regression model was constructed to determine the associations between the SNPs and AF based on the above screened results.Odds ratios (ORs) and 95％ confidence interval (CI) were calculated to assess the strength of the correlations.Moreover,we downloaded the genotype data from the HapMap Project for linkage disequilibrium analysis ofrs17042171.Results:AF patients were likely to be of older age and longer left atrial diameter and had more coronary artery disease and higher hypertension compared with the control group (P＜0.05).Among the 5 SNPs,the frequency distribution of genotype AA for rs17042171 was significantly different between the AF and control groups (P＜0.05).After adjusting for several covariates,there was still a high risk ratio in patients with the AA genotype compared with the AC+CC genotype (OR:5.591,95％CI 2.176 to 14.365,P-B＜0.008).Similarly,stratification analysis on the AA genotype demonstrated significant differences between rs17042171 and persistent AF.However,there were not significant correlations between AF and the control groups for the other 4 SNPs (P＜0.05).Conclusion:Rs17042171,near PITX2 on chromosome 4q25,is associated with AF susceptibility in the Chinese Han population from the central plains,suggesting that this SNP can provide a new strategy for clinical diagnosis in AF patients.

Objective This study explored the effects of Epimedium koreanum Nakai(EK)on liver function in normal,kidney yang deficiency(KYANGDS),and kidney yin deficiency(KYINDS)rats based on the theory of"You Gu Wu Yun."The study also investigated the connection between EK-induced liver injury and symptoms.Methods Seventy-two male SD rats were divided into normal,KYANGDS,and KYINDS groups using the random number table method.The KYANGDS model was established through intramuscular injection of 20 mg/kg of hydrocortisone,whereas the KYINDS model was established through daily gavage of 160 mg/kg of thyroid tablet suspension for 14 consecutive days.After successful modeling,the rats were divided into the normal,EK low-dose,EK high-dose,KYANGDS,KYANGDS+EK low-dose,KYANGDS+EK high-dose,KYINDS,KYINDS+EK low-dose,and KYINDS+EK high-dose groups using the random number table method.Animals in the drug groups were administered low(0.26 g/kg)and high(0.77 g/kg)EK extract doses through continuous gavage.The other groups received drinking water once a day for 28 consecutive days.Changes in body mass were monitored during the administration period,and serum alkaline phosphatase(ALP),alanine transaminase(ALT),aspartate transaminase(AST),direct bilirubin,indirect bilirubin(IBil),and total bilirubin(TBil)were measured at the end of administration using biochemical analyzers.The liver weight,visceral body ratio,and visceral brain ratio were measured.Hematoxylin and eosin staining were performed to observe the pathological changes in the liver.Results Compared with the normal group,the EK high-dose group showed a decrease in body weight on the 21st day during the drug administration period and an increase in IBil(P<0.05);the KYANGDS group had lower body weight at each measurement time point from the third to the 28th day,higher ALP,and lower liver weight(P<0.05).Compared with the KYANGDS group,the KYANGDS+EK high-dose group had decreased ALP levels(P<0.05).The pathological damage of liver tissue in each KYANGDS administration group improved,the presence of fat vacuoles were reduced,and pathological scores show a decreasing trend.Compared with the KYINDS group,KYINDS+EK high-dose group exhibited a higher IBil level and a lower visceral brain ratio(P<0.05).Conclusion EK has a small effect on the liver function of rats with KYANGDS within the dose range;however,it has a specific hepatogenic impact on normal and KYINDS rats,and EK-induced liver injury and the symptoms may be associated with each other.
