ObjectiveTo investigate the association between a new identified Gly82Ser polymorphism of RAGE gene and diabetic microangiopathy,a case control study of 260 Chinese subjects (including 156 type 2 diabetics with or without nephropathy or retinopathy and 104 non diabetic control) was performed.MethodsGenotype frequencies of Gly82Ser polymorphism were studied by PCR RFLP analysis with AluI digestion.ResultsThe most frequent genotype and allele of Gly82Ser polymorphism of RAGE gene in Chinese were genotype GG and allele G.Their frequency distribution showed significant difference between Chinese and Caucasian.There was no difference in genotype frequencies or allele frequencies between type 2 diabetic patients (DN 0) and the control subjects.Genotype and allele frequencies did not differ in type 2 diabetic subjects with nephropathy or without nephropathy.Moreover,there were no associations between diabetic patients with or without retinopathy in genotype and allele frequencies as well (two tailed Fisher’s exactP >0.05).ConclusionOur results showed that Gly82Ser polymorphism in RAGE gene was not associated with diabetic microangiopathy,which suggests that these genetic variants may not be involved in the mechanism of diabetic microangiopathy in Chinese type 2 diabetics.

Objective To compare the differences between three kinds of reconstruction methods of the multi-planar spiral CT in diagnosing fractures of skull base , in order to appraise fractures of skull base in forensic medical examinations. Method 40 cases with suspicious basio-cranial fractures after cranio-cerebral trauma were examined by multi-planar spiral CT scanning. The data were imported into workstation for ax-ial scanning, multi-planar reconstruction (MPR) and 3D-reconstruction (using SSD). Results In 24 cases with anterior fossa fractures, 9 cases were found by axial scanning, 24 cases by MPR, 9 by SSD. The comparison between these groups showed significant statistical difference (P

Objective To explore the effect and mechanism of atorvastatin on pulmonary hypertension (PAH) in chronic pulmonary heart disease.Methods Seventy eight patients with chronic pulmonary heart disease were randomly signed into treating group and observing group.Forty healthy people were picked up from people taking physical examination at the same stage as control group.Patients in observing group were given routine treatment,and patients in treating group were given atorvastatin (20 mg/d) supplement beside routine treatment.Pulmonary function,ultrasound cardiogram,plasma interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were measured before and after 24 weeks of treatment.Results There were no difference in terms of forced expiratory volume in one second(FEV1),FEV1/forced vital capacity(FVC),pulmonary arterial pressure (PAP) and the levels of IL-6 and TNF-α between the observing group and treating group before treatment(P ＞ 0.05).While there were significant difference in terms of the serum levels of IL-6,TNF-α and PAP of treating group,observing group and normal control group at before treatment (IL-6:(106.61 ± 31.34) ng/L,(105.33 ± 30.16) ng/L,(73.81 ± 31.12) ng/L,F =67.17 ; TNF-α:(19.41 ± 10.21) ng/L,(18.25 ± 11.37) ng/L,(14.82 ± 4.33) ng/L,F =15.43 ; PAP:(58.33 ± 8.95) mmHg,(56.04 ± 8.57) mmHg,(15.88 ±7.01) mmHg,F =88.78;P =0.00),and these levels in observing and treating group were higher than those in normal control group(P ＜0.01).After 24 weeks treatment,the IL-6,TNF-α,PAP in the treating group were (73.90 ± 27.12) ng/L,(14.91 ± 5.35) ng/L and (45.96 ± 5.61) mmHg respectively,significantly lower than those in observing group ((103.00 ± 28.12) ng/L,(17.22 ± 7.17) ng/L and (53.11 ± 9.21) mmHg respectively; P =0.025,0.045 and 0.031 respectively).The pulmonary function indexes including FEV1 and FEV1/FVC in treating group were much better than those in observing group at 24 weeks treatment (FEV1:(57.85±10.31)％ vs.(43.9±31.33)％;FEV1/FVC:(57.83±10.38)％ vs.(47.97± 14.79) ％ ;P =0.001,0.024 respectively).Conclusion Atorvastatin can effectively improve the life quality and pulmonary function,decrease PAP of patients with chronic pulmonary heart disease,and the mechanism may be related to the inhibition of inflammation in pulmonary vessels.

ObjectiveTo explore the applied methods and the effect of double-cavity balloon urinary catheter in the treatment of epistaxis.MethodsClinical data of 96 epistaxis patients who were operated with postnasal packing applied double-cavity balloon urinary catheter at our unit were analyzed retrospectively.ResultsAll patients ( 100％ ) were successfully healed.One patient suffered from anterior nostril stenosis because of the constriction by urinary catheter.The rest was no significant complications.ConclusionPostnasal packingl applied double-cavity balloon urinary catheter had a safe and effective method for treatment of severe epistaxis.Attention to detail in the operation could prevent the occurrence of complications.

Objective To immunoscreen one protein antigen gene from a cDNA library of cysticercus cellulosae. Methods The cDNA library of cysticercus cellulosae was immunoscreened by using the serum of patient with cerebral cysticercosis. After the insert of positive clone was amplified by PCR and subcloned into pUC18, the nucleotide sequence of the cDNA was determined by the dideoxynucleotide chain termination method using a Taq DyeDeoxy Terminator Cycle Sequencing Kit. The homological search of the nucleotide sequence was done by using BLASTN in NCBI. Results A cDNA clone (named cY1) with a length of 546 bp was isolated. The clone contained one open reading frame composed of 474 bp encoding 158 amino acids. The nucleotide sequence of cY1 showed 99% homology with one immunogenic protein gene named NC-9 of cysticercus cellulosae. Conclusion A gene encoding protein antigen of cysticercus cellulosae is cloned.

Objective To immunoscreen one protein antigen gene from a cDNA library of Cysticercus cellulosae . Methods A cDNA library of C. cellulosae was constructed after cDNA was synthesized, and immunoscreened using rabbit anti C. cellulosae polyclone antibody. The gene structure and its possible function were analyzed by comparing with the sequences available in the GenBank, after the insert of positive clone was subcloned to pBluescript SK plasmid and the nucleotide sequence of the cDNA was determined by dideoxynucleotide chain termination method using a Taq DyeDeoxy Terminator Cycle Sequencing Kit. The amino acid sequence was deduced from nucleotide sequence using GENETYX software. Homological search of the nucleotide sequences was done using BLAST in GenBank. Results and Conclusion A cDNA clone of 1 320 bp was isolated. The clone contained one open reading frame composed of 1 260 bp encoding 420 amino acids, in which two potential glycosylation sites were found. The partial nucleotide sequence of the gene fragment showed high homology with the essential spectrin gene of Caenorhabditis elegans and the erythrocyte surface antigen gene of Plasmodium falciparum , when the gene fragment was homologically analyzed in GenBank.

OBJECTIVE To inquire into the risk factors of uremia patients with fungus infection and search for the effective methods to prevent and control it.METHODS All the cases of the 82 uremia patients with fungus infection in the clinic of our hospital were analyzed.RESULTS The sites of the fungus infection were intestines and stomach,blood vessel,respiratory tract,oral cavity,reproductive tract,skin soft tissue and urinary tract.The common fungus infection was Candida albicans,about 60.61 per cent.The risk factors of uremia patients with fungus infection were the old age,several underlying diseases,hypoimmunity,not using medicine properly during the treatment and invasive operation.CONCLUSIONS The effective methods to prevent and control fungus infection are as the follows: to improve the staff′s awareness of the danger of fungus infection,be strict to the rules of hospital isolation and sterilization,and be try to reduce invasive operation.We should strengthen the cleaning of the wards and the crew's hands,strengthen the monitoring of quality and pay more attention to the primary treatment.We should use the medicine properly,especially the use of antibiotics,immune suppressants and hormones,and pay attention to result of culture from the microbiological laboratory.We should cure the underlying diseases actively and improve the suffers′ immunity function.
