Objective To study the Ile796Val polymorphism in human SCAP gene in Hubei area, and analyze its correlation with coronary heart disease (CHP) and hypertension and the relationship between polymorphism and lipid metabolism. Methods Using PCR RFLP, we detected genotypes of Ile796Val polymorphism in human SCAP gene. Results The allele A frequencies of Ile796Val in human SCAP gene for controls, CHD patients and the hypertension patients were 0.32, 0.45 and 0.42 respectively. The allele G frequencies were 0 68, 0.55 and 0.58 respectively. There were significant differences in frequencies of genotype and alleles between controls and hypertension group. And there was significant difference in the level of TC, LDL C and ApoB. In CHD group, there was significant difference in the TC level between different genotypes. In hypertension patients, although a difference was noted in genotype, there was no significant difference in allele frequencies and lipid level exceps a significant difference in the levels of TC, LDL C and ApoB in hypertension patients. Conclusion Ile796Val polymorphism in human SCAP gene may be a great agent to cause disorder in the lipid level of blood and lipid metabolism of tissue. It is of great significance in disorder in lipid metabolism of inter cellular and genetic investigation of hyperlipidemia.

Objective To evaluate the safety and efficacy of OUR Rotating Gamma System in neurosurgical clinical application. Methods Based on the results of animal experiments, 2381 patients with intracranial disease were treated using OUR Rotating Gamma System in Aohai Gamma Knife Center of Navy General Hospital of PLA betwean December 1996 and November 2002. There were 1288 males and 1093 females and their age ranged from 3 to 84 years (mean 45.8 years). 1020 patients had benign intracranial tumors, and of them 446 suffered from pituitary tumors, 254 meningioma, 148 craniopharyngioma and 103 vestibular schwannomas. Malignant tumors were diagnosed in 796 patients, among them glioma was found in 360 and metastasis in 360. 374 patients had cerebral arteriovenous malformations (AVMs) and 191 functional neurological disorders. Treatment technique of Gamma Knife Stereotactic Radiosurgery, dose prescription and precise orientation performed in intracranial tumor or foci were analyzed, and the preliminary outcome of treatment was evaluated in this study. In addition, the management of the possible complication and adverse reaction was studied. Results Gamma Knife Stereotactic Radiosurgery alone, or combined with other treatment procedures, could cure some of selected patients with benign brain lesions including pituitary neoplasms, meningioma, vestibular schwannomas, AVMs, and craniopharyngioma etc. And this treatment was also beneficial to some patients with malignant tumors. The incidence of radiation edema was 0.75%. Conclusions The clinical results suggest that Gamma Knife Stereotactic Radiosurgery is a very effective, accurate and relatively safe neurosurgical tool used either as a primary or adjuvant procedure for treatment of intracranical pathologic processes. However, it might lead to some severe or fatal complications if used inappropriately. Thus, optimal result would not be obtained unless a careful and precise Gamma treatment based on the operative rules and the effective management for postoperative complications are well planned.

Objective To detect adenovirus from children with acute upper/lower respiratory tract infections and to investigate the genetic evolution of virus .Methods A total of 1 178 clinical specimens were collected from the Children ’ s Hospital , Zhejiang University School of Medicine during March 2011 and February 2013, including 513 throat swabs from children with acute upper respiratory tract infection and 665 nasopharyngeal aspirates from children with acute lower respiratory tract infections .Besides, 9 specimens in an outbreak of adenovirus infection during 2011 and 2014 were also collected .Adenovirus was identified by real-time fluorescent polymerase chain reaction (RT-qPCR).The hypervariable region (HVR)-7 region of hexon gene in positive samples was amplified and sequenced for typing and phylogenetic analysis .Other respiratory viruses were also detected with RT-qPCR in adenovirus positive samples .Clinical characteristics of adenovirus infection were analyzed in children with lower respiratory tract infections .Chi-square test and Fisher exact probability were used for data analysis .Results Among 1 178 samples from sporadic cases , 104 samples (8.83%) were adenovirus positive .The rates of adenovirus infection in upper respiratory tract infection group and lower respiratory tract infection group were 13.65%(70/513) and 5.11%(34/665), respectively (χ2 =26.193, P<0.05).Compared with that in lower respiratory tract infections , positive rates of adenovirus were higher in upper respiratory tract infections in children aged 0-1 year and >3 years (χ2 =6.575 and 7.334, P<0.05 or <0.01).Adenovirus infection might occur throughout the year and peaked in spring and summer .Among 54 adenovirus-positive samples from 104 sporadic cases , adenovirus types 1, 2, 3, 4, 7 and 31 were identified in 4, 6, 26, 2, 15 cases and 1 case, respectively.While among 9 adenovirus-positive samples from outbreak cases , type 4 and type 3 were identified in 1 and 8 cases, respectively .The HVR-7 region of hexon gene was highly homologous in the same type , and the sequence alignment indicated that the sequence of HVR-7 might have regional differences .Nine out of 70 children (12.86%) were co-infected with other virus in upper respiratory tract infection group , while the rate of co-infection in lower respiratory tract infection group was much higher [58.82%(20/34), χ2 =24.045, P<0.05 ].There was no significant difference in clinical manifestations between children infected with adenovirus only and those with co-infection in lower respiratory tract infection group (P>0.05), but two children with co-infection died.Conclusions Adenovirus infection is more common in upper respiratory tract infection .Adenovirus type 3 and type 7 are the most prevalent serotypes in sporadic cases , while type 3 is the most prevalent serotype in outbreak cases .

Objective To investigate the genetic variation and molecular evolution of human bo-cavirus 1 (HBoV1) strains isolated during 2009 to 2014 in Hangzhou, China.Methods Throat swab sam-ples were collected from children with acute respiratory tract infections in the Children′s Hospital Affiliated to the Zhejiang University School of Medicine from 2009 to 2014.Real-time PCR was performed for the detec-tion of HBoV1 strains.Fifteen HBoV1 strains with high virus load were screened out for the amplification and sequencing of complete genomes.The complete genomes were submitted to GenBank for further analysis with bioinformatics software.Results A total of 48 nucleotide mutations were detected in the complete genomes of 15 HBoV1 strains, resulting in 11 amino acid mutations with 5 of them located in the active region of phospholipase A2 ( PLA2) .The 15 HBoV1 isolates along with 16 HBoV1 strains in GenBank were classified into three clusters as indicated by the phylogenetic analysis based on their complete coding sequences.All of the 15 strains were belonged to clusterⅠ, the representative strain of which was the Sweden prototype strain ST2.The phylogenetic trees constructed using genes encoding the capsid proteins VP1 and VP2 were highly similar to those based on the complete coding sequences.The estimated mean evolutionary rate of HBoV1 with regard to the complete coding sequence was 3.03×10-4(95%HPD, 2.14×10-4-3.92×10-4 ) substitu-tions per site per year.With regard to each gene, the NS1 gene was considered to the most conserved gene while the NP1 gene showed the highest substitution rate.The dN/dS ratios (ω) of the four genes were all less than 1, indicating that all of them were under negative selection.Moreover, the VP2 gene was under the strongest negative selection, while the NP1 gene was under the weakest negative selection.Conclusion All of the HBoV1 isolates circulating in Hangzhou province during 2009 to 2014 were belonged to ST2 genotype with a relatively high mutation in the area of PLA2.Despite the complete genome was conservative, its evo-lutionary rate was high.Among the four genes, the NP1 gene showed the highest substitution rate.All of the four genes were under negative selection, of which the VP2 gene was under the strongest negative selection.

The connotations of "du-fu" and "Sanli" in "Sanli acupoint for du-fu diseases" are discussed in this paper, which can provide theoretical foundation for the clinical application of "Sanli acupoint for du-fu diseases". Based on ancient literature combined with related theories in the Huangdi Neijing (Yellow Emperor's Canon of Internal Classic), a deep discussion is performed through the relationship between Zusanli (ST 36) and stomach, indication and mechanism of Zusanli (ST 36) on du-fu diseases and comparison between Zusanli (ST 36) and Shousanli (LI 10). It is believed that "du" should be pronounced as "dŭ", meaning stomach, and it indicates that Zusanli (ST 36) is closely related to stomach and spleen when it is used for du-fu diseases; "fu" means abdomen area, including liver-gallbladder, spleen, stomach-intestine, kidney, uterus, triple energizer; "sanli' means exclusively the acupoint of Zusanli (ST 36).

Objective To evaluate the status of abnormal glucose metabolism in patients being alive over 3years after liver transplantation and discuss the possible mechanism of post-transplant diabetes mellitus ( PTDM ).Methods In this study, the clinical data of patients with liver transplantation were collected from April 2001 to December 2008. Patients with diabetes mellitus before operation and those who had died and failed to appear during follow-up were exluded. 199 patients living over 3 years after liver transplantation were follow-up. The prevalence of PTDM was evaluated according to fasting plasma glucose(FPG). Among those without diabetes according to FPG,32patients underwent 75 g oral glucose tolerance test (OGTT) , and fasting and 2 h plasma glucose and insulin were determined. 32 patients were divided into three groups [normal, impaired glucose regulation ( IGR ) , and PTDM groups], proportion of PTDM and homeostasis model assessment ( HOMA ) index were calculated. Results In patients alive over 3 years after liver transplantation, the prevalence of PTDM was 34.67% according to FPG. The OGTT result showed that the proportion of PTDM was 9.38%, IGR, including impaired fasting glucose(IFG) and impaired glucose tolerance ( IGT ) , was 56. 25% , while 34. 37% remained normal. The homeostasis model assessment β cell function index( HOMA-β ) decreased progressively from normal group, IGR group to PTDM group,and that in PTDM group was significantly lower than those in normal and IGR group( P＜0.01 ). IGR group had the highest homeostasis model assessment for insulin resistance (HOMA-IR) and PTDM group the next, and HOMA-IR in IGR group was significantly higher than normal group. Conclusion In patients alive over 3 years after liver transplantation, the prevalence of PTDM reached 44.05%. Insulin resistance existed during early period of impaired glucose regulation, while the degeneration of β cell progressed with the worsening of impaired glucose regulation.

Geographic tongue, also called benign migratory glossitis, is a common and superficial benign inflammatory disorder that affects the tongue epithelium. The majority of geographic tongue lesions typically manifest as irregular central erythematous patches. These lesions, which are caused by the loss of filiform papillae, are defined by an elevated whitish band-like border that can change location, size, and pattern over a period of time. Histological observations of the oral mucosa affected by geographic tongue revealed nonspecific inflammation. Some reports described cases of migratory stomatitis, wherein lesions simultaneously manifested on the extra lingual oral mucosa. This condition is also called ectopic geographic tongue, which is clinically and histologically similar to the type normally confined to the tongue. In most cases, patients are asymptomatic and do not require treatment. The condition may spontaneously exhibit periods of remission and exacerbation with good prognosis. The specific etiology of geographic tongue remains unknown. Geographic tongue is age-related and is prevalent among young individuals. Various etiological factors that have been suggested in literature include immunological factors, genetic factors, atopic or allergic tendency, emotional stress, tobacco consumption, hormonal disturbances, and zinc deficiency. Geographic tongue may coexist with other disorders, such as fissured tongue, psoriasis, diabetes mellitus, gastroin- testinal diseases, burning mouth syndrome, and Down syndrome. Experts currently disagree on whether geographic tongue is an oral manifestation of psoriasis. Moreover, some scholars suggest that geographic tongue is a prestage of fissured tongue. The objective of this review is to summarize current research on risk factors of geographic tongue.
