Objective To investigate the clinical manifestation and inspection method about abnormal uter-ine bleeding due to cesarean section scar diverticulum.Methods retrospective analysis of 156 abnormal uterine bleeding cases due to cesarean section scar diverticulum.Analysis the relevance ratio,the starting time of clinical symptom,related influencing factors,the information of examine and misdiagnose.Results there are 12 cases cesare-an section scar diverticulum in 2010;30 cases in 2011;26 cases in 2012;37 cases in 2013;51 cases in 2014.The starting time of clinical symptom is 1 ~6 month pose menstrual in 48 cases;6 months to 2 years pose menstrual in 89 cases,2 years later pose menstrual in 19 cases.98 cases don′t have evidential abnormality even through many times ultrasonograph.43 patients subjected diagnosis curettage.The uterine bleeding time obviously longer comparing retro-position of uterus with anteposition and msposition of uterus.Conclusion the morbidity of abnormal uterine bleeding cases due to cesarean section scar diverticulum is low,but the rate of misdiagnosis and missed diagnosis is little high-er.We need to elevate the rate of diagnosis,and to research the preservation and magagement gradually.
2.Research advance in primary ovarian Burkitt lymphoma
Chinese Journal of Primary Medicine and Pharmacy 2022;29(8):1271-1275
Among all non-Hodgkin's lymphoma, primary ovarian Burkitt lymphoma (POBL) is a rare disease. Tumors can occur in one or both ovaries. The main symptoms of POBL are abdominal pain or a large abdominal mass. The differential diagnosis of POBL based on imaging characteristics and histopathological examination is the basis for further treatment of ovarian tumors from different sources. Although most patients with POBL have undergone surgical treatment after the discovery of ovarian masses, chemotherapy rather than surgery should be the main treatment method for them. Active chemotherapy combined with preventive central nervous system therapy leads to good prognosis. A variety of treatment schemes have been adopted, which greatly increase the survival rate of patients with POBL. In this review, we retrieved related literature and retrospectively reviewed the epidemiology, clinical manifestation, diagnosis and treatment of POBL. The purpose of this review is to draw clinicians' attention to the possibility of POBL when performing differential diagnosis of ovarian tumors.

Non-Camellia tea is a part of the colorful Chinese tea culture, and is also widely used as beverage and medicine in folk for disease prevention and treatment. In this study, 37 samples were collected, including 33 kinds of non-Camellia teas and 4 kinds of teas (Camellia). Traditional functions of non-Camellia teas were investigated. Furthermore, non-Camellia teas of original plants were characterized and identified by molecular methods. Four candidate regions (rbcL, matK, ITS2, psbA-trnH) were amplified by polymerase chain reaction. In addition, DNA barcodes were used for the first time to discriminate the commercial non-Camellia tea and their adulterants, and to evaluate their safety. This study showed that BLASTN and the relevant phylogenetic tree are efficient tools for identification of the commercial non-Camellia tea and their adulterants. However, some sequences from original plants have not been found and there is a limitation of sequence number of original plants in GenBank. Submitting more original plant sequences to the GenBank will be helpful for evaluating the safety of non-Camellia teas.
