Objective To systematically review the efficiency of 18 F-FDG PET in glioma grading by using Meta-analysis. Methods Retrieval in PubMed and China National Knowledge Infrastructure (CNKI)was performed. Relevant papers concerning with glioma diagnoses with 18 F- FDG PET were selected. Paper quality was evaluated according to the standard of diagnostic test recommended by Cochrane Workshop. The data of glioma malignancy degree defined as semi-quantitatively and qualitatively were extracted from the papers. Meta-analysis was conducted with the Meta-Disc software to calculate pooled weighted sensitivity and specificity with 95% confidence interval (CI). Summary receiver operating characteristic (SROC) curve was performed and the areas under the curve (AUC) were calculated. Results Seven hundred and fifty-three patients from 17 papers ( 16 in English, 1 in Chinese) were included. Two hundred and seventy-two patients from 11 papers were using semi-quantitative (tumor to cortex ratio, T/C; tumor to white matter ratio,T/W) method and 481 patients from 9 papers were using qualitative method (visual observation, some of the papers had 2 or more methods). After heterogeneity test was done, different effect models were selected. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR) with 95% CI for T/C group was 0. 952 (95% CI: 0. 903 -0. 980), 0. 409 (95% CI: 0. 318-0. 504) and 11. 746 (95% CI:5. 368-25. 702) respectively. The pooled weighted sensitivity, specificity and DOR with 95% CI for T/W group was 0. 857 (95% CI: 0. 768-0. 922), 0. 538 (95% CI: 0. 431 -0. 642) and 22. 066 (95% CI:7. 077-68. 800) respectively. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR)with 95% CI for qualitative method was 0.810 (95%CI: 0.757-0.855), 0.870 (95%CI: 0. 819-0.911 ) and 15.282 (95% CI: 3. 716-62. 851 ) respectively. The AUC for T/C group, T/W group and qualitative method was 0.8604, 0. 8373 and 0. 8724 respectively. Conclusions Grading glioma by 18 F-FDG PET with semi-quantitative method may provide high diagnostic sensitivity. If qualitative method is used, the diagnostic specificity may be higher.

OBJECTIVETo investigate the effect and mechanism of Scutellaria Baicalensis Stem-leaf Total Flavonoid (SSTF) on lipid metabolism in hyperlipidemic rat.

METHODOn the basis of establishing hyperlipidemia rat model, blood lipids, lipid metabolic enzyme, antioxidative capacity were investigated after 30 days feeding of fatty emulsion.

RESULTSSTF significantly reduced the serum TC, TG, LDL-C, ApoB concentration and increased HDL-C and ApoAI levels, improved the activity of lecithin cholesterol acyltransferase (LCAT). SSTF was shown to decreased MDA content in both serum and liver, increased serum SOD activity.

CONCLUSIONSSTF could remarkably modulate the lipid metabolic disorder in hyperlipidemic rats, and has a certain regulating function on lipoprotein, inferring that it could reduce the occuring of atherosclerosis. The mechanism of regulating lipid metabolism might be related with the increasing activity of LCAT and antioxidative capacity.

OBJECTIVETo observe the effect of Shen warming Pi strengthening method on expressions of serum T cell subsets (C045+%, C03+%, and C04 +/COB+) in diarrhea-predominant irritable bowel syndrome (IBS-0) rats. Methods An IBS-0 rat model was established referring to AL-Chaer's modeling method combined with tail clamp and intragastric administration of sanna leaf. After modeling 30 SO rats were randomly divided into 6 groups according to random digit table, i.e., the model group, the high, middle, low dose Wenshen Jianpi Recipe (WJR) groups, and the Sishen Pill control group, 6 in each group. A normal control group consisting of 6 SO rats were also set up. Rats in high, middle, low dose WJ R groups were administered by gastrogavage with boil-free WJ R at the daily dose of 3. 100, 1. 550, 0. 775 g/kg, respectively. Rats in the Sis hen Pill control group were administered by gastrogavage with boil-free Sis hen Pill at the daily dose of 0. 736 g/kg. Equal volume of normal saline was given by gastrogavage to rats in the model group and the normal control group. All medication lasted for 2 successive weeks. Rats' general state, expressions of T cell subsets (CD45+%, CD3+%, and CD4+ /CDB+) changes were observed.

RESULTSCompared with the normal control group, expressions of CD45+% and CD3+% increased, but CD4+ /CDB+ decreased with statistical difference (P < 0. 05). Compared with the model group, expressions of CD45+% and CD3+% decreased, but CD4+ ICDB+ increased with statistical difference in high, middle, low dose WJR groups, and the Sis hen Pill control group (P <0. 05). Compared with the Sis hen Pill control group, there was statistical difference in all indices except CD45+ value in the low dose SWPSM group (P <0. 05). Compared with the low dose WJ R group, the expression of CD3+% decreased in high and middle dose WJR groups, and the Sis hen Pill control group; CD4+ /CD8+ increased in the Sishen Pill control group and the high dose SWPSM group (all P < 0. 05).

CONCLUSIONSWJR showed better treatment effect. The mechanism of Shen warming Pi strengthening method might be achieved by regulating expressions of CD45+% and CD3+%, and CD4+ /CD8+ ratios.

Objective To identify mutations site and clinical characteristics of a familial hypercholesterolemia(FH) proband diagnosed clinically through DNA sequencing and family analysis in the proband and his family members of 3 generations.Methods Blood samples and clinical data of the kindred of total 29 from 3 generations members were collected.Proband had a physical examination electrocar-diogrom and vascular ultrasound.The proband and his family members took routine clinical exams,and genomic DNA was isolated.The promoter region and the 18 exons of low density liporotein receptor(LDLR) gene were screened by Touch down polymerase chain reaction -single strand conformation polymorphism(PCR-SSCP) and DNA sequencing.The result of sequencing were matched gene sequence published in the BLAST database.Results 1.Increased intima-media thickness and plaque were detected in the common carotid artery,right subclavian artery of the proband.Aortic valve regurgitation was found by echocardiography.2.No mutation R3500Q of ApoB100 was observed.3.Two heterozygous mutations in exon 10 and 13 of LDLR gene (W462X and A606T) were identified.The proband and 5 members of paternal relatives showed W462X heterozygosis mutation in exon 10 of LDLR gene which introduced the change from tryptophone to a new stop codon.The proband's mother and grandmother harboured A606T heterozygous mutation in exon 13 of LDLR gene due to a single base pair substitution of G for A in the codon for residue 1 879.Conclusions Disease causing mutations of proband are W462X and A606T compound heterozygosis mutation in exon 10 and 13 of LDLR gene inherited from mother and father.Proband shows homozyous phenotype though the genotype analysis indicates heterozygous mutations.

OBJECTIVEIBS-D rat model was established to assess the effect of Shen warming Pi strengthening method (SWPSM) for intervening diarrhea-predominant irritable bowel syndrome (IBS-D) by observing rats' general state, stool properties, AWR ranking, and histopathological changes.

METHODSTotally 72 rats were randomly divided into 6 groups, i.e. the normal group, the model group, the high, middle, low dose SWPSM groups, and the control group, 12 in each group. The IBS-D rat model was successfully established referring to AL-Chaer ED's modeling method. After modeling high, middle, and low dose SWPS Recipe boil-free granules were given by gastrogavage to rats in corresponding treatment groups. Sishen Pill boil-free granule was given by gastrogavage to those in the control group. Equal volume of normal saline was given by gastrogavage to rats in the model group. The medication lasted for 2 weeks. Rats' general state, stool properties, abdominal withdrawal reflex (AWR) ranking, and histopathological changes were observed.

RESULTSAfter treatment, the general state of all rats got im- provement to various degrees. The improvement in the high and middle dose SWPS Recipe groups were superior to that in the low dose SWPS Recipe group and the control group (P < 0.05). There was no statistical difference in the growth rate between after and before treatment in each group (P > 0.05). Compared with the model group and the low dose SWPS Recipe group, the defecation amount within 4 h was less in the high and middle dose SWPS Recipe groups and the control group (P < 0.05). The Bristol ranking score, average ranking of loose stool, ratio of dry stool and wet stool were lower in the high and middle dose SWPS Recipe groups than in the control group and the low dose SWPS Recipe group (P < 0.05). The AWR ranking score was lower in the high and middle dose SWPS Recipe groups than in the control group when the volume of balloon dilation was 1.5 mL. There was no organic change of histological or morphological observation.

CONCLUSIONSHigh sensitive IBS-D model was proved to be reliable. SWPSM could reduce the quantity of stools, lower Bristol ranking score, average ranking of loose stools as well as ratios of dry stool and wet stool, contributing to reducing the high sensitivity of rats' visceral organs to some extent.

To evaluate the expression of cyclin dependent kinase inhibitor P27(Kip1) in leukemia and to investigate its clinical significance, the P27(Kip1) protein in bone marrow or peripheral blood samples from 82 cases of leukemia was measured by Western blot and enhanced chemoluminescence (ECL). The results showed that the expression of P27(Kip1) protein in ALL was higher than that in ANLL (P = 0.033) and also that in CML (P = 0.008). P27(Kip1) expression in CLL was higher than that in CML too (P = 0.017). In acute leukemia, the effective rate (CR and PR) of initial chemical therapy in the group of P27(Kip1) > 0.655 was higher than that in the group of P27(Kip1) < or = 0.655, P = 0.041. For ANLL and ALL patients, the survival time in the group of P27(Kip1) > 0.655 was longer than that in the group of P27(Kip1) < or = 0.655, P = 0.0065. There were similar statistical significance for ANLL and ALL patients, P = 0.0271 and P = 0.0266 respectively. There was a negative correlation between chromosomal abnormalities and P27(Kip1) expression in ALL patients (r = -0.775, P = 0.04). The expression of P27(Kip1) protein appeared nothing to do with sex, age, white blood cell number, blast cell number in peripheral blood, serum LDH or uric acid. In conclusion, the expression level of P27(Kip1) protein is in relation to the effect of initial chemical therapy and survival time, so that the lower P27(Kip1) expression may associated with poor prognosis in acute leukemia.

Abstract?AIM:To investigate the effective treatment methods of corneal injury caused by chestnut thorns and the factors affecting the disease progression.?METHODS: From Jul.2014 to Oct.2015, the clinical data of 15 patients(15 eyes) with corneal injury caused by chestnut thorns in Ophthalmology Inpatient Department of Wuhan Tongji Hospital was retrospective analyzed. The patients without fungal keratitis were treated with the surgery of removing chestnut thorn from cornea and antifungal drugs. For the patients complicated with fungal keratitis, besides surgery of removing chestnut thorn and antifungal drugs, anterior chamber irrigation and corneal stroma injection with fluconazole solution were given to treat the disease.If necessary, amniotic membrane transplantation or keratoplasty was also given to the patients complicated with fungal keratitis. After that, the effectiveness of those methods and the factors affecting progression were analyzed.?RESULTS:For 11 patients without fungal keratitis, the average time between corneal injury and receiving treatment at Tongji Hospital was 1-7 (2.42±2.15) d and for 4 patients complicated with fungal keratitis, the average time was 3-30 (18.25±4.35)d.Among 15 cases, statistics suggested that the average number of chestnut thorn in patients complicated with fungal keratitis was 4.5, and all the chestnut thorn penetrated the cornea into the anterior chamber.The average number of chestnut thorn in patients without fungal keratitis was 3.5, and the proportion of chestnut thorn penetrated the cornea into the anterior chamber was 28.5%.After treatment, all patients had no new fungal keratitis or other complications.Those results indicated that the different treatments for the patients with or without fungal keratitis were all effective.?CONCLUSION:The factors affecting the progression of cornea foreign body injury caused by chestnut thorn are the number of chestnut thorn, whether chestnut thorn penetrate the cornea into the anterior chamber, time since injury, active anti -fungal therapy. If patients complicated with fungal keratitis could be treated with antifungal agents and anterior chamber irrigation or corneal stroma injection using fluconazole solution without delay, the progress of fungal keratitis could be effectively controlled, and favorable conditions for further therapy such as amniotic membrane transplantation or keratoplasty could be provided.
