Objective To evaluate the effectiveness of thermal tomography in breast cancer (BC) screening. Methods We conducted a general population-based BC screening in three regions of Hubei Province (Xiantao, Hongan, and Yangxin Districts). Participants underwent a questionnaire-based interview for baseline data collection. They then received a physical examination, thermal tomography, and ultrasound from doctors and technicians. We compared the efficacies, including sensitivity, specificity, and false-positive rates, of ultrasound and thermal tomography in BC screening. Results A total of 59 712 eligible women were included in this screening program. The BI-RADS 1, 2, 3, 4, and 5 accordance rates between the two screening methods were 0.9549, 0.8047, 0.9037, 0.3352, and 0, respectively. The overall accordance rate was 0.933 1. The kappa consistency results showed that the Cicchetti-Allison and Fleiss-Cohen kappa values were 0.7970 and 0.8583, respectively. Although the two methods had equal sensitivities, specificity was higher in thermal tomography than in ultrasound. The false-positive rate was lower in thermal tomography than in ultrasound. The area under the receiver operating characteristic (ROC) curve of thermal tomography was significantly larger than that of ultrasound. Conclusion The general consistency between thermal tomography and ultrasound in BC screening was high. Thermal tomography outperformed ultrasound in terms of specificity and diagnostic efficiency. Therefore, thermal tomography has a high application value for general population-based BC screening.

Objective:To discuss the medication, prescription law and academic thoughts of doctors in the Ming and Qing Dynasties for the treatment of abdominal tympanites based on the Yi An Lei Ju. Methods:The medical records of doctors in the Ming and Qing Dynasties for the treatment of tympanites contained in Yi An Lei Ju were retrieved, and the prescription information was extracted. Based on R4.2.1 and the TCM inheritance calculation platform V3.0, the frequency, property and taste, and meridian tropism, and efficacy categories of drugs were counted, and association rules analysis and clustering analysis were performed. Results:A total of 214 prescriptions were included, involving 239 kinds of Chinese materia medica, with a total frequency of 2 080 times. The high-frequency drugs (frequency≥30) were Poria, Citri Reticulatae Pericarpium, Alismatis Rhizoma, Atractylodis Macrocephalae Rhizoma, Aconiti Lateralis Radix Praeparata, etc. The medicinal properties of the drugs were mainly warm, neutral and cold. The flavors were mainly pungent, sweet and bitter. The meridians were mainly spleen, liver and kidney meridians. The efficacy categories were mainly tonic drugs, diuresis and dampness drugs, and qi-regulating drugs. Association rule analysis found that the most frequently used drug pair was Poria-Citri Reticulatae Pericarpium. Clustering analysis showed that drugs (frequency≥20) could be divided into 4 clusters.Conclusions:Doctors in the Ming and Qing Dynasties treated abdominal tympanites with the basic treatment methods of invigorating the spleen and promoting diuresis, soothing the liver and regulating qi, warming the kidney and resolving fluid retention. The medication took into account the ascending and descending of qi, the combination of attack and supplement, the combination of cold and heat, and the harmony of qi and blood.

【Objective】 To investigate the sperm retrieval rate (SRR) of microdissection testicular sperm extraction (M-TESE) in patients with non-obstructive azoospermia (NOA) caused by different causes. 【Methods】 A retrospective analysis was performed on 225 NOA patients during Jan.2020 and Dec.2022. The relation between SRR and patients’ age,body mass index (BMI),testicular volume,endocrine hormones and different etiological classifications were analyzed. 【Results】 According to whether sperm was obtained by surgery,the patients were divided into two groups,including 107 cases in the sperm group and 118 cases in the non-sperm group. There were no significant differences in patients’ age,testicular volume and levels of endocrine hormones between the two groups (P>0.05). According to the different causes,NOA patients with mumps history,cryptorchidism history,AZFc deletion or Klinefelter syndrome (KS) had higher SRR,while idiopathic NOA patients had the lowest SRR (P<0.05). 【Conclusion】 M-TESE is an effective treatment of NOA. There is no correlation between SRR and patients’ age,MBI,testicular volume and levels of endocrine hormones. NOA caused by different etiological classifications may have different SRR.

Objective To study the effect of mitochondrial reactive oxygen species(ROS)on male fertility and its application value in assisted reproduction so as to provide a new method for fertility assessment and etiological treatment of male infertility.Methods The relationship between sperm ROS and male infertility,sperm nuclear DNA integrity and sperm membrane function was analyzed.Then the relationships of the ROS of sperms for fertiliza-tion with fertilization rate,cleavage rate,embryo rate and pregnancy outcome were analyzed.Results(1)The percentage of the high ROS in sperm membrane of the male infertility group was significantly higher than that of the normal fertility group(P<0.01),but there was no statistical difference in the percentage of the high ROS in the sperm mitochondria between the two groups.(2)The normal rate of sperm membrane function in the normal group was significantly higher than that in the abnormal group(P<0.01),but there was no significant difference in the sperm DNA fragmentation index(DFI)between the groups.(3)There was significant difference in the fertilization rate between the IVF control group and IVF observation group,but no significant difference was seen in the cleavage rate,excellent embryo rate and clinical pregnancy rate between the groups.Conclusion Sperm ROS is related to male fertility to some extent.Abnormal ROS may lead to impaired sperm membrane function and affect sperm fertilization ability,thus affecting male fertility.The detection of ROS in sperm can be used as a new method to evaluate male fertility and provide a basis for diagnosis or treatment of male infertility.For patients with ART or infertility,the appropriate time to conceive can be selected according to the sperm ROS level.

Microbes play important roles in human health and disease. The interaction between microbes and hosts is a reciprocal relationship, which remains largely under-explored. Current com-putational resources lack manually and consistently curated data to connect metagenomic data to pathogenic microbes, microbial core genes, and disease phenotypes. We developed the MicroPhenoDB database by manually curating and consistently integrating microbe-disease associ-ation data. MicroPhenoDB provides 5677 non-redundant associations between 1781 microbes and 542 human disease phenotypes across more than 22 human body sites. MicroPhenoDB also pro-vides 696,934 relationships between 27,277 unique clade-specific core genes and 685 microbes. Dis-ease phenotypes are classified and described using the Experimental Factor Ontology (EFO). A refined score model was developed to prioritize the associations based on evidential metrics. The sequence search option in MicroPhenoDB enables rapid identification of existing pathogenic microbes in samples without running the usual metagenomic data processing and assembly. Micro-PhenoDB offers data browsing, searching, and visualization through user-friendly web interfaces and web service application programming interfaces. MicroPhenoDB is the first database platform to detail the relationships between pathogenic microbes, core genes, and disease phenotypes. It will accelerate metagenomic data analysis and assist studies in decoding microbes related to human dis-eases. MicroPhenoDB is available through http://www.liwzlab.cn/microphenodb and http://lilab2. sysu.edu.cn/microphenodb.

Objective Our retrospective study was aimed to analyze the clinical significance of microsurgical clipping and intravascular embolization in patients with intracranial aneurysm (IA).Methods Clinical data of 86 patients with IA received treatment at our hospital from February 2010 to November 2014 was retrospectively analyzed.Patients were divided into two groups according to the treatment method, IE group (intravascular embolization,43 cases)and MC group (microsurgical clipping,43 cases).The general information,treatment effect, hospitalization expenses and time and the rate of complication of the patients between two groups were compared.Results There was no sta-tistical difference in general information between two groups (P >0.05).The cure rate of patients in IE group was obviously better than that in MC group (P <0.01).The hospitalization expenses in IE group was lower than that in MC group,and the hospitalization time was shorter than that in MC group,all the differences had statistical significance (P <0.01).The rate of complication in IE group was obviously lower than that in MC group (P <0.01).Conclusion The clinical effect of intravascular embolization was significantly better than microsurgical clipping,which is worth promoting in clinic.

Objective To investigate clinical effect of kidney essence granule on DNA intergrity in patients with idiopathic weak sperm.Methods 110 cases of idiopathic weak sperm disease in outpatient service of male infertility were selected, and divided into 3 groups using random number table method, treatment group (n=40) treated with strong kidney essence granule and control group (n=40) by Wuzi Yanzong pill treatment, blank control group (n =30) given placebo treatment.Semen parameters and sperm DNA fragmentation index (DFI) differences were compared within groups.

Objective To assess the therapeutic value of transcatheter arterial chemoembolization combined 125iodine seed implantation for primary hepatic carcinoma with portal vein tumor thrombus.Methods The data of 23 patients ranging from 34 to 70 years old [ average age ( 56 ± 8) years ] with primary hepatic carcinoma with portal vein tumor thromhosis of type Ⅱ and type Ⅲ were retrospectively collected.The tumor number of liver parenchyma ranged from 1to 15 ( median number 4).The average diameter of tumor thrombus was (20.5 ± 1.5 ) mm and average length was ( 37.4 ± 2.6 ) mm.All of the tumors of liver parenchyma in 23 patients were treated by transcatheter arterial chemoembolization (TACE) and tumor thrombus were treated with 125iodine seed implantation.Before the 125iodine seed implantation,the formula dosage,the number,the spatial distribution,the intensity of radioactivity and the matched peripheral dosage of seed were calculated by treatment planning system (TPS).Then the 125iodine seeds were implanted in different levels and locations of port vein thrombosis under CT guided.Results The follow-up period ranged from 1to 26 months.The times of transcatheter arterial chemoembolization were 1to six times (median time 3.1±0.4) and the 125iodine seed implantation in the port vein thrombosis were 1to 2 times ( median time 1.4 ± 0.5 ).The numbers of implanted 125iodine seeds were 4 to 17 ( median number 7.0 ± 1.0).The median survival time was 18.0 months (3-24 months).The 3,6 and 12 months survival rates were 91.3％ ( 21/23 ),69.6％ ( 16/23 ),and 60.9％ ( 14/23 ).There was no severe side-effect related to therapy.Conclusions Transcatheter arterial chemoembolization combined 125iodine seed implantation for portal vein tumor thrombosis could significantly prolong the median survival time of patient with primary hepatic carcinoma with portal vein tumor thrombosis.

OBJECTIVE:To detect the expression of genes of leukemia cell line K562 treated by artemisinin using the gene chip technology and to study the mechanism of artemisinin in the inhibition of leukemia cell line K562 on the molecular level. METHODS:K562 cells were treated with artemisinin for 24h,and then the morphological change of K562 cells were observed under invert microscope and fluorescence microscope. The cell cycle state was examined by flow cytometry analysis (FCM). Total RNA samples were extracted and reverse transcribed to cDNA. Cy3-labelled cDNA samples were hybridized with gene chips.The hybridization results were detected by Gene Pix 4100A. RESULTS: Under invert microscope,different degree of shrinkage of K562 cells was noted,karyoschisis was reduced,cell density was decreased and the numbers of drift cells were increased.Under fluorescence microscope,caryotin was highly concentrated,marginalized and agglomerated to relucent clump,i.e.apoptotic body. Flow cytometric analysis showed that ratio of cells in G2 phase increased markedly. Hybridization analysis showed down-regulation of cyclin D1,cdk4,cdk2,cdc2,DNA-PK,DNA-TopoI,mcl-1,erk,jnk and VEGF in the artemisinin-treated K562 cells.CONCLUSION: The mechanism for artemisinin to inhibit the proliferation of leukemia cell line K562 is related to its action to alter the gene expression of certain regulatory substances involved in cell cycle and induce apoptosis of leukemia cell line K562.
