In order to investigate the mutation of HBV polymerase gene reverse transcription conserved region (P region) in chronic hepatitis B (CHB) patients, 212 CHB patients who took antiretroviral treatment with nucleotide analogues were chosen. The drug resistance mutations of HBV P region and HBV genotype were detected by Pyrosequencing. Sequence analysis showed that the drug resistance sites of HBV P region located at sites 173; 180; 181; 184; 204; 236 and 250. The main site of HBV P region drug resistance was 204 and 180, accounting for 35.8% and 23.5%, respectively. There were significant differences in the mutation rate of site 180 among different age groups. There were also significant differences in the mutation rate of site 204 among younger than 30 age group, 41 to 50 age group and 51 to 60 age group. (P < 0.05, P < 0.01). The mutation rate of site 180 combined with site 204 was 66.6%. The mutation rate of site 181 combined with site 236 was 23.3%. The age of C genotype infected patients was significantly older than B genotype infected patients (P < 0.01). M204V/I mutation mostly existed in the form of joint L180M mutation, the mutation rate was age-related. The detection of HBV genotypes and drug resistance sites of HBV P region have important clinical implications for the treatment and prognosis of patients with CHB.

With China's emphasis on innovation in national development, local medical and pharmaceutical universities/colleges need to establish research teams for innovation, in which the formation of team spirit is essential. A good team is beneficial to the development of research leaders, the advancement of the discipline, and the outcome of researches, which all contribute to the development of the university.

Hypophosphatasia (HPP) is caused by loss-of-function mutation(s) of the gene that encodes the tissue-nonspecific isoenzyme of alkaline phosphatase (TNSALP). Its manifestations are variable, including impaired skeletal mineralization, altered calcium and phosphate metabolism, recurrent fractures, pain, impaired mobility, premature tooth loss, developmental delay, and seizures.There are different attempts for HPP.Asfotase alfa (Strensiq?), is a bone-targeted recombinant TNSALP which has shown significant improvements in morbidity and mortality in patients with perinatal and infantile hypophosphatasia, and it can improve growth, mobility function and quality of life.This enzyme replacement therapy has generally been well-tolerated, with most adverse reactions being mild-to-moderate in nature.This article reviews recent advances in the treatment of the disease.

Objective:To explore the values of electroencephalogram (EEG) combined with glial fibrillary acidic protein (GFAP) in the early diagnosis and prognosis evaluation of viral encephalitis (VE).Methods:A total of 63 patients with VE admitted to the Hangzhou Seventh People′s Hospital from January 2016 to December 2019 were selected as the observation group. In addition, 80 healthy people suspected of central nervous system disease in the same period were selected as the control group. The data of gender, age, body mass and body mass index (BMI) were recorded, the Niolet V32 digital EEG instrument of American Nigolli Company was used for EEG inspection, and the level of serum GFAP was detected by enzyme-linked immunosorbent assay (ELISA). The general data, abnormal EEG results and the level of serum GFAP of the control group and the observation group were compared. The diagnostic values of EEG and its combination with serum GFAP in VE were analyzed by four grid table; and the diagnostic value of serum GFAP for VE was evaluated by drawing receiver operating characteristic (ROC) curve.Results:There was no significant difference in sex, age, body mass and BMI between the two groups ( P>0.05). The results of EEG diagnosis for VE showed that 11 of 63 cases were missed and 10 of 80 cases in the control group were misdiagnosed, and the sensitivity, specificity and accuracy of EEG diagnosis for VE were 82.54%, 87.50% and 85.31%, respectively. Compared with that of the control group, the level of serum GFAP of the observation group was higher: (460.19 ± 126.53) ng/L vs. (217.36 ± 53.17) ng/L, t =15.525, P<0.05. ROC curve showed that area under curve (AUC) of serum GFAP for VE diagnosis was 0.907 and cutoff value was 238.37 ng/L. The sensitivity, specificity and accuracy of EEG combined with serum GFAP in diagnosing VE were 93.65%, 83.75% and 88.11%, respectively, and the sensitivity and accuracy of EEG combined with serum GFAP were higher than those of EEG and GFAP alone. The results of 12-month follow-up showed that 20 of 63 VE patients had sequel (poor prognosis group), 43 patients had good prognosis (good prognosis group), and the incidence of adverse prognosis was 31.75%(20/63). There were significant differences in EEG and GFAP between the good prognosis group and poor prognosis group ( P<0.05). Conclusions:The sensitivity and accuracy of EEG combined with serum GFAP in the diagnosis of VE are good, which may be used for the early diagnosis and prognosis evaluation of VE.

Environmental arsenic exposure is a worldwide public health problem. Long-term exposure to inorganic arsenic is closely related to diseases such as cardiovascular disease, diabetes and malignant tumors. Different dietary structure and intake of certain specific nutrients may have important effects on the pathogenic effect of arsenic. This article summarizes the effects of dietary nutrients on arsenic toxicity, providing reference for the follow-up arsenic toxicity research and reducing the risk of arsenic-related diseases through nutritional intervention.

Objective: To study the relationship of the expressions of new apoptosis-related gene (PDCD)5 and p53 in oral normal mucosa, oral leukoplakia and oral squamous cell carcinoma. Methods: The expressions of PDCD5 and p53 were observed separately in 17 samples of oral normal mucosa, 60 of oral leukoplakia, and 30 of oral squamous cell carcinoma by Immunohistochemical means. Results: PDCD5 positive rate in oral normal mucosa was 88.2%, in oral leukoplakia was 63.3%, and in oral squamous cell carcinoma was 30%. P53 positive rate in oral normal mucosa was 0, in oral leukoplakia was (31.7%), and in oral squamous cell carcinoma was 60%. There was a negative relationship between (PDCD5) SII and P53 SII in every lesion. Conclusion: It suggests that both PDCD5 and p53 could be used as molecular markers of carcinogenesis for oral epithelium.

Objective To prepare the recombination protein and polyclonal antibodies against human apolipoprotein A5(ApoA5)and detect the expression of ApoA5 in human tissues with the antibody,then further study the fuction and serum level of ApoA5.Methods With PCR and gene recombinated techniques,the prokaryotic ApoA5 expression vector was constructed.The His-ApoA5 fusion protein was expressed in E.ColiM15,and the fusion protein was injected into New Zealand rabbits to prepare polyclonal antibody.The antibody was tested for their specificity with ELISA and Western-blot,then it was used to detect the tissue distribution of ApoA5.Results It was found that there was a specific brand at 40 ku of the recombination ApoA5(rApoA5);the polyclonal antibody had high immunoreactivity and specificity.ApoA5 was expressed in human sera and hepatic tissue,not in other tissues(heart,vessel,spleen,intestine and lung),regardless of the lipid level.Conclusion The pQE30-ApoA5 is constructed successfully,the rApoA5 can be expressed in E.Coli M15;ApoA5 antibody has highly specifity.It can be used in clinical test.There is ApoA5 in human serum,and ApoA5 is expressed in liver which may be significant in lipid metabolism.

Objective To investigate the status of high-risk human papilloma virus(HR-HPV)infection and natural clearance in males whose wife have been infected,and to analysis the coincidence rates of HPV subtypes in couples.Methods Urethra epithelial cells and urethral secretions of 246 males whose wife infected with HR-HPV have been enrolled in the study to detect 13 kinds of HPV subtypes and redetect after 1 year.Results The natural clearance rate of HR-HPV in male was 31.82％(35/110).The infection rate was 44.72％(110/246)in initial detection,while 30.49％(75/246) in redetection,the difference was statistically significant(χ2=10.612,P<0.05).The coincidence rate of HPV subtypes in couples was 15.04％(37/246)in initial detection,while 8.94％(22/246)in redetection,the difference was statistically significant(χ2=4.333,P<0.05).The frequency percentage of HPV16,18 increased significantly in male,the difference was statistically significant(χ2=35.991,P<0.05).Conclusion HR-HPV can be cross-transmitted between infected women and their spouses.It is necessary to detect for her husband once women have been detected high-risk HPV positive.
