OBJECTIVE To investigate the distribution of familial hepatitis B virus (HBV) genotypes and analyze the relationship between genotypes and clinical outcome. METHODS A total of 136 cases of familial hepatitis B were involved in this study,including 25 cases of asymptomatiec HBV carriers (ASC),85 cases of chronic hepatits B (CHB),24 cases of liver cirrhosis (LC) and 4 cases of hepatocellular carcinoma (HCC). Nested polymerase chain reaction-restriction fragment length polymorphism (ntPCR-RFLP)was used to identify the genotypes of HBV. RESULTS There were 124 cases with hepatitis genotype C,7 cases with genotypes B+C mixed,3 cases with genotype B and 2 cases that did not conformed to be any of genotypes from A to H. Genotype C in the HCC was predominant genotype (100%),next in the LC(96%),CHB (95.3%) and ASC(66.7%).Compared with genotype C,genotypes B and B+C only existed in ASC and CHB,the proportion was 9.5% vs 23.8% and 1.2% vs 2.3%,respectively. There were no other HBV genotypes from A to H seen in familial hepatitis B in Shanxi province. CONCLUSIONS HBV genotype C is the major one in familial hepatitis B in Shanxi. There are a few genotypes B and B+C existed. Genotype C induces a relatively bad prognosis.

Objective To validate the determination method of microbacteria limit of Shuitiaosan powder .Methods Plate counting method was used .The method of counting bacteria and mould was validated by the recovery rates with 5 control strains .The method of checking control bacteria was validated by observing cultivation of Staphylococcus aureus and Pseudomonas aeruginosa in the test group, positive control group and negative control group in the same environment .Results The recovery rate of every trail strains was higher than 70%when centrifugal sedimentation methods were used in the counting bacteria and mould .To the examination of con-trol bacteria , Staphylococcus aureus and Pseudomonas aeruginosa were detected by the centrifugal sedimentation methods .The tested strains were observed in the test group and in the positive control group .No strains were observed in the negative control group .Con-clusion The methods are simple , feasible, reliable and can be used for the examination of microbacteria limit .

Objective To investigate the relationships between expressions of HPV and EBV in larynge-al carcinoma. Methods DNA flow-through hybridization and gene chip genotyping technology(HybriMax)and real-time quantitative PCR were used for 37 subtypes of HPV detection and quantitative detection of EBV in 101 cases of laryngeal cancer paraffin embedded tissue specimens. 43 cases of vocal cord polyp of paraffin embedded tissue specimens were used as the controls. Results The positive rate of laryngeal carcinoma was 13.86% in group HPV and 9.3% in the control group ,with no statistically significant difference between the positive expres-sions of HPV in the laryngeal carcinoma group and control group(P>0.05). The positive rate of laryngeal carci-noma was 63.37% and 13.95%,respectively ,in group EBV ,and the control group ,with significant difference between them(P < 0.05). In respect of the positive rate by comparing differently differentiated EBV in laryngeal carcinoma ,there was no significant difference in the positive expression of EBV in well differentiated and differen-tiated laryngeal carcinoma(P>0.05),but the difference was statistically significant in highly differentiated EBV as compared with those with low differentiation type,medium differentiation and poor differentiation(P < 0.05). There was no significant difference between the groups in view of sex ,age and course of disease in the patients (P > 0.05). Conclusions The incidence of laryngeal carcinoma is closely related with EBV infection ,possibly relationed with HPV and high-risk subtypes of HPV have a certain role in the process of induced laryngeal carcino-ma. The gender ,age and duration of disease have no significant correlation with EBV infection. This study will provide a basis for further invesgitation of pathogenesis of laryngeal cancer and prevention and treatment of larynge-al cancer.

The outbreak of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 has rapidly spread globally. Cancer patients are at a higher risk of being infected with the coronavirus and are more likely to develop severe complications, as compared to the general population. The increasing spread of COVID-19 presents challenges for the clinical care of patients with gynecological malignancies. Concerted efforts should be put into managing gynecological malignancies in an orderly manner by strictly implementing the measures that are specifically developed for controlling the spread of COVID-19. We have drafted Recommendations on Management of Gynecological Malignancies during the COVID-19 Pandemic based on our experience on controlling COVID-19 pandemic in China. We recommend that patients with gynecological malignancies should be managed in hierarchical and individualized manners in combination with local conditions related to COVID-19. Medical care decision should be balanced between controlling COVID-19 pandemic spread and timely diagnosis and treatment for gynecologic oncology patients.
