OBJECTIVE To observe the efficacy and safety of ticagrelor combined with Compound xueshuantong capsules in the treatment of unstable angina pectoris. METHODS Totally 120 patients with unstable angina pectoris with deficiency of Qi and Yin combined admitted to Sanmenxia Hospital of Traditional Chinese Medicine from January 2021 to December 2022 were randomly divided into clopidogrel group (group A), ticagrelor group (group B) and combined medication group (group C), with 40 patients in each group. In addition to conventional treatment, group A was given clopidogrel orally; group B was given ticagrelor orally; group C was given ticagrelor and Compound xueshuantong capsule orally. After 12 weeks of treatment, the clinical efficacy, frequency of angina attacks, coagulation function indicators, cardiac function indicators, traditional Chinese medicine syndrome efficacy, and the incidence of adverse cardiovascular events and bleeding incidence were evaluated in the 3 groups. RESULTS The total effective rates of group A, group B and group C were 77.5%, 85.0% and 90.0%, respectively. The incidence of adverse cardiovascular events and bleeding events were 7.5%, 7.5% and 5.0% in the respective groups, with no statistically significant difference (P>0.05). The frequency of angina attacks, duration of angina attacks and duration of dyspnea were significantly reduced or shortened in all 3 groups after treatment compared to before treatment (P<0.05). The frequency of angina attacks in group C was significantly lower than that in groups A and B after treatment (P<0.05). The levels of fibrinogen (FBG) and D-dimer in all 3 groups were significantly lower after treatment compared to before treatment (P<0.05); group A had significantly higher levels of FBG and D-dimer compared to group B and C (P<0.05). The left ventricular end-diastolic diameter and left ventricular end-systolic diameter in all three groups were significantly shorter after treatment, and the left ventricular ejection fraction was significantly higher compared to before treatment (P<0.05), but there were no statistically significant differences among those groups (P>0.05). The total effective rates of traditional Chinese medicine syndrome efficacy in groups A, B and C were 67.5%, 80.0% and 87.5%, respectively, with group C being significantly higher than group A (P<0.05). CONCLUSIONS In addition to conventional treatment, ticagrelor combined with Compound xueguantong capsules can more significantly reduce the frequency of angina attacks in patients with unstable angina pectoris, reduce the levels of FBG and D- dimer, improve traditional Chinese medicine syndrome efficacy, and do not increase the risk of bleeding.

Arabidopsis thaliana is an important and long-established model species for plant molec-ular biology,genetics,epigenetics,and genomics.However,the latest version of reference genome still contains a significant number of missing segments.Here,we reported a high-quality and almost complete Col-0 genome assembly with two gaps(named Col-XJTU)by combining the Oxford Nanopore Technologies ultra-long reads,Pacific Biosciences high-fidelity long reads,and Hi-C data.The total genome assembly size is 133,725,193 bp,introducing 14.6 Mb of novel sequences compared to the TAIR1 0.1 reference genome.All five chromosomes of the Col-XJTU assembly are highly accurate with consensus quality(QV)scores>60(ranging from 62 to 68),which are higher than those of the TAIR10.1 reference(ranging from 45 to 52).We completely resolved chro-mosome(Chr)3 and Chr5 in a telomere-to-telomere manner.Chr4 was completely resolved except the nucleolar organizing regions,which comprise long repetitive DNA fragments.The Chr1 cen-tromere(CEN1),reportedly around 9 Mb in length,is particularly challenging to assemble due to the presence of tens of thousands of CEN180 satellite repeats.Using the cutting-edge sequencing data and novel computational approaches,we assembled a 3.8-Mb-long CEN1 and a 3.5-Mb-long CEN2.We also investigated the structure and epigenetics of centromeres.Four clusters of CEN180 monomers were detected,and the centromere-specific histone H3-like protein(CENH3)exhibited a strong preference for CEN 180 Cluster 3.Moreover,we observed hypomethylation patterns in CENH3-enriched regions.We believe that this high-quality genome assembly,Col-XJTU,would serve as a valuable reference to better understand the global pattern of centromeric polymorphisms,as well as the genetic and epigenetic features in plants.

Complex structural variants(CSVs)are genomic alterations that have more than two breakpoints and are considered as the simultaneous occurrence of simple structural variants.How-ever,detecting the compounded mutational signals of CSVs is challenging through a commonly used model-match strategy.As a result,there has been limited progress for CSV discovery com-pared with simple structural variants.Here,we systematically analyzed the multi-breakpoint con-nection feature of CSVs,and proposed Mako,utilizing a bottom-up guided model-free strategy,to detect CSVs from paired-end short-read sequencing.Specifically,we implemented a graph-based pattern growth approach,where the graph depicts potential breakpoint connections,and pattern growth enables CSV detection without pre-defined models.Comprehensive evaluations on both simulated and real datasets revealed that Mako outperformed other algorithms.Notably,validation rates of CSVs on real data based on experimental and computational validations as well as manual inspections are around 70%,where the medians of experimental and computational breakpoint shift are 13 bp and 26 bp,respectively.Moreover,the Mako CSV subgraph effectively characterized the breakpoint connections of a CSV event and uncovered a total of 15 CSV types,including two novel types of adjacent segment swap and tandem dispersed duplication.Further analysis of these CSVs also revealed the impact of sequence homology on the formation of CSVs.Mako is publicly available at https://github.com/xjtu-omics/Mako.

Objective To explore the surgical technique and preliminary results of endoscopic nipple-sparing mastectomy (E-NSM) and immediate pre-pectoral implant-based breast reconstruction (BR) with titanium-coated polypropylene mesh (TiLoop Bra) via single axillary incision for breast cancer patients. Methods The clinical data of 9 consecutive female patients who underwent E-NSM and immediate pre-pectoral implant-based BR with TiLoop Bra from March to May 2021 were retrospectively analyzed. The mean age of patients was 40.6 (22-60) years. The operation time, early complications were collected, and the patients' social and mental health, breast satisfaction and chest function before and after the operation were assessed with the BREAST-Q questionnaire. Results All the patients had unicentric tumor with a mean diameter of 2.4 (0.6-4.7) cm. The mean distance from the tumor to the nipple was 2.5 (2-4) cm. There were 2 patients with tumor stage 0 and 7 patients with stageⅠ. The mean operation time was 161.1 (125-201) min, the mean blood loss was 41.1 mL and the hospital stay time was 1.5 d. There were 5 patients in the day-care unit. All the patients were successfully followed up with a median follow-up time of 1 (1-2) month. One (11.1%) patient with depigmentation of the nipple-areola complex caused by mild ischemia. None of the patients had incision complications, subcutaneous emphysema, hematoma, infection, nipple-areola or skin flaps necrosis, implant loss. During the follow-up period, no local/regional recurrence or distant metastasis was found. Chest well-being was decreased in the first month after the surgery compared with preoperative status, and the difference was statistically significant (P=0.001). There was no statistical difference in the breast satisfaction or psychosocial function scores between pre- and post-operation (P>0.05). Conclusion E-NSM and immediate pre-pectoral implant-based BR with TiLoop Bra via single axillary incision has minimal trauma, rapid postoperative recovery, short operation time, few early complications and good early cosmetic effect, and the short-term result is satisfactory.

OBJECTIVE:
To explore the correlation of different glucose metabolism statues with chronic kidney disease (CKD) in middle-aged and elderly individuals in Lanzhou.
METHODS:
Based on the baseline data of REACTION Study in Lanzhou area, we randomly sampled 10 038 residents aged 40-75 years in 3 communities in Lanzhou, who were classified into normal glucose tolerance (NGT), impaired glucose regulation (IGR) and diabetes groups. The estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (ACR) were used to assess the renal function and albuminuria, respectively. Binary logistic regression was performed to analyze the contribution of the risk factors to CKD. Polynominal regression was used to determine the trends of eGFR with the increment of ACR.
RESULTS:
Among all the participants, the prevalences of albuminuria, CKD and renal insufficiency (RI) were 26.2%, 27.4% and 2.5%, respectively. The prevalence of albuminuria, CKD and RI were significantly higher in the diabetes group than in IGR and NGT groups (
CONCLUSIONS
Diabetes mellitus is a significant risk factor for albuminuria and RI, while IGR is not. Screening for albuminuria and eGFR is highly recommended for individuals with diabetes, hypertension, and obesity, especially in women and the elderly population.

10. Design and application status of three-component total ankle replacement prosthesis
Chinese Journal of Tissue Engineering Research 2020;24(30):4847-4853
BACKGROUND: The early total ankle replacement has been abandoned for long times due to the insufficient understanding of the ankle joint biomechanics, higher implant failure rates and complications. With the updating of the design concept about ankle prosthesis, total ankle replacement surgery is now more and more popular among surgeons. At present, the three-component total ankle replacement prosthesis is considered to be more in line with the normal biomechanical requirements of the ankle joint, and has been gradually promoted for clinical application. OBJECTIVE: To understand the biomechanics of the ankle joint, summarize the design features of the three-component total ankle joint replacement prostheses, and summarize experience for further prosthetic design. METHODS: The first author used a computer to search CNKI and PubMed for the literature on total ankle replacement prostheses from inception to February 2020. The key words were “total ankle replacement prosthesis design, STAR prosthesis, HINTEGRA prosthesis, BOX prosthesis”. RESULTS AND CONCLUSION: (1) The STAR, HINTEGRA, and BOX prostheses have shown acceptable survival rates and clinical results in clinical applications; however, a large number of cases and long-term follow-up were also required. (2) The designs of the three kinds of total ankle replacement prostheses all focus on restoring the anatomy of the physiological ankle joint, reproducing the axis of motion of the ankle joint, being compatible with the geometry of the ligament, and reducing the mechanical alignment of the tissue around the ankle joint. (3) To achieve maximum ligament compatibility, the articular surface design of the prosthetic component must be two physiological anatomic shapes or two non-physiological anatomic shapes. (4) There is a significant difference between the shape of the Chinese ankle and that of Caucasian. We are looking forward to design and develop a more suitable prosthesis for Chinese peoples.
