Objective To evaluate the application of flow-through rapid hybridization technique and gene chip (HybriMax) on human papiUomavions (HPV) subtype in Chongqing.Methods Cervical tissue samples were taken under the colpnscope form 473 females who had cervical lesion for pathological analysis.The predictive value of HybriMax in cervical abnormality was compared with pathological results,which were used as golden standard.Resuits 13 different subtypes were found and total HPV positive rate was 63.0% (284/473) Among the 17 different subtypes ,the higher positive rote HPV subtypes were HPV16 (23.7%,112/473),HPV58 (12.7% ,60/473),HPV53(7.4% ,35/473).The HPV infection rates were higher with the worse d cervical lesion(X2=77.06,P＜0.01).Conclusions The most frequent subtypes of HPV infection in Chongqing cervical lesion were HPV 16,58.HybriMax was an effective method to detect HPV subtype in clinical.

Objective: To study relationship among ambulatory pulse pressure (PP), pulse pressure index (PPI) and carotid intima-media thickness (IMT) in aged patients with hypertension. Methods: The 24h ambulatory blood pressures of 159 subjects were measured, and their ambulatory PP [(mean systolic blood pressure (SBP) - mean diastolic blood pressure (DBP)] and ambulatory PPI (ambulatory PP/mean SBP) were calculated. Color Doppler ultrasonography was used to measure carotid IMT. Relationship between ambulatory PPI and carotid IMT was analyzed. Results: Pearson correlation analysis indicated that carotid IMT was correlated with age (r=0.353), mean SBP (r=0.594), mean DBP (r=-0.355), ambulatory PP (r=0.855) and ambulatory PPI (r=0.883), P<0.001 all. Multivariant gradual regressive analysis indicated that carotid IMT possessed significant linear correlation with ambulatory PP and ambulatory PPI (R2=0.789), and standardized regression coefficient β of ambulatory PPI (β=0.621) was higher than that of ambulatory PP (β=0.284). Conclusion: Ambulatory pulse pressure index and ambulatory pulse pressure are good indicators for evaluation of carotid arteriosclerosis, and value of ambulatory pulse pressure index is more than.

[Objective]To analyze the clinical and pathological characteristics of myoepithelial carcinoma of nasopharynx,as well as its relationship with Epstein-Barr virus.[Methods]We report twelve cases of myoepithelial carcinoma of nasopharynx,study its clinical,histopathologic,and immunohistologic features,follow-up data and EBERS in-situ hybridization.[Results]Among age of patients ranged from 24 to 65 years(mean age=46 years).Imagery data demonstrated an extensive nodosity filling the nasopharynx,Of these 12 cgses,myoepithelial markers such as S-100,SMA,P63,CK14,CK5/6 and epithelial markers such as CK,CKL,CKH were not always all expressed at one case,but at less one of these two kind of markers expressed at one cage.The results of EBERS in-situ hybridization of 12 cases were negative.[Conclusion]Myoepithelial carcinoma is a low malignat tumor.It seldom takes place in nasopharynx,dispite its morphologic heterogeneity it has some special morphologic and immuohistologic characteristics as well as special result of EBERS in-situ hybridization,which may support its diagnosis.The combinde radiotherapy and chemotherapy after surgical removal of the tumor will control the recurrence and metabasis effectively.

Objective To analyze the distribution of human papillomavirus (HPV) genotype in the diseases associated with HPV infection and explore the role of HPV genotype in these diseases. Methods Retrospective analysis was carried out to compare HPV genotypes of 353 outpatients suffering the diseases associated with HPV infection including cervical caner,cervical intraepithelial neoplasia (CIN),genital duc condyloma,and subclinical cervical human papillomavirus infection (SPI) in our department from January to October 2008. HybriMax were used to detect HPV genotype. The distribution data of HPV genotype were statistically analyzed. Results Totally 176 HPV positive females were found with a positive rate of 49.86%. HPV positive rate in cervical cancer was 100%,and all of them were high risk HPV. The positive rate was increased with the severity of CIN,and the higher histological-grade was,the higher HPV positive rate was (P

In this paper, the situation on antisense oligonucleotide as a means of gene therapy was outlined, and the main factors impeding its progress at present was summarized. The one of main factors is the efficiency of antisense oligonucleotide as a drug and the other is the side-effect in clinical use. At the level of cell and gene, these influential factors were analyzed in detail. The main factor that makes side-effect in using antisense oligonucleotide is the difficulty to distinguish effectively homologous-gene from target gene. The another factor is the secondary structure and three-dimensional structure of target gene that seriously affect antisense oligonucleotide to arrive at target position. The third problem is what can affect antisense oligonucleotide transmission and quick annealing. How use computer technique to analyze fully the target gene of antisense oligonucleotide including the secondary structure and homology of target gene, and to design effective antisense oligonucleotide, in order to reduce its side-effect in clinical use of antisense oligonucleotide as a drug of gene therapy, and the computer-aid design method were described.

Coronavirus disease 2019 (COVID-19) is a highly contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). More than one-third of patients with COVID-19 experience neurological symptoms, including confusion, headaches, and decreased/disordered taste. Alzheimer's disease (AD) is a slowly progressive neurodegenerative disease and the most common type of dementia. Alzheimer's disease patients are at high risk and susceptible to infection with COVID-19, which may cause severe illness and even death. There appears to be an interaction between AD and COVID-19, and on the one hand, patients with COVID-19 seem to be more likely to develop AD. AD patients, on the other hand, may be more susceptible to severe COVID-19. Therefore, understanding the common link between COVID-19 and AD may help to develop treatment strategies. Risk factors common to AD and COVID-19 are aging, ApoE ε4 allele, β-amyloid (Aβ) deposition, angiotensin-converting enzyme (ACE), neuroinflammation, oxidative stress. Here, this article focuses on the relationship between COVID-19 and AD, explores common risk factors and potential pathogenesis, and provides help for early prevention, treatment and recovery.

OBJECTIVETo observe the effects of Xiaobai Decoction (XBD) in reducing albuminuria and shortening the duration of albuminuria in patients with pregnancy-induced hypertension syndrome (PIH) in puerperium.

METHODSEighty-five patients were given the conventional treatment with magnesium sulfate for relieving convulsion and lowering hypertension, at the same time, the treated group was given XBD additionally with the modification according to the symptoms. The treatment course for both groups was 14 days. Routine test of midstream urine was performed every three days, and 24 h-urinary protein was measured every week.

RESULTSThe therapeutic effect on the 43 patients of the treated group was markedly effective in 11 (25.6 % ), effective in 26 (60.4%) and ineffective in 6 cases (14.0%), the total effective rate being 86.0%; while in the 42 patients of the control group, the corresponding numbers were 5 (11.9%), 21 (50.0%), 16 (38.1%) and 61.9%, respectively, the efficacy of the former was significantly better (P < 0.05).

CONCLUSIONXBD is a simple, safe and effective drug for reducing albuminuria and shortening the duration of albuminuria in puerperium of PIH patients.

The genetic diversity of three Tibetan herbs, i. e., Sang-Di, E-Dewa and Ye-Xingba (Tibetan names), was studied based on the field collection, specimen identification and DNA sequence analysis. Swertia hispidicalyx, Gentiana lhassica and Scrophularia dentata, as the original plants of the three Tibetan herbs, were collected and identified. The regions of ITS, matK, rbcL, rpoC1, trnL(UAA), psbA-trnH, atpB-rbcL, trnS (GCU)-trnG(UCC), rpl20-rps12, trnL(UAA)-trnF(GAA) and nadl 2nd intron were amplified and sequenced. The ITS regions of S. hispidicalyx and S. dentata were cloned and sequenced, and the sequences were classified into different genotypes. All the sequences were analyzed and compared with those of closely related species. Our studies may provide reference for the genetic diversity analysis and molecular identification of the three Tibetan herbs.
