OBJECTIVE To provide a reference for anticoagulant therapy and pharmaceutical care of the breast cancer patient with pulmonary thromboembolism （PTE） accompanied by multiple comorbidities. METHODS Clinical pharmacists participated in the diagnosis and treatment of a breast cancer patient with PTE accompanied by severe thrombocytopenia and suspected antiphospholipid syndrome secondary to systemic lupus erythematosus， and provided personalized pharmaceutical care as developing individualized anticoagulation plans and monitoring patient bleeding. For the occurrence of PTE， the clinical pharmacist recommended stopping all breast cancer drugs. The clinical pharmacists also cleared that severe thrombocytopenia was not the absolute contraindication for anticoagulant treatment and suggested fondaparinux sodium as the initial anticoagulation regimen. Further， warfarin was recommended as the long-term anticoagulation regimen with a recommended treatment course of at least 3-6 months by the clinical pharmacists. Whether to continue indefinite anticoagulation therapy was based on the results of the antiphospholipid antibodies after 12 weeks combined with the tumor treatment regimen. RESULTS The physicians adopted the advice of the clinical pharmacists. After treatment， the patient’s blood phlegm and anhelation disappeared and the platelets returned to normal. The patient was allowed to be discharged with medication. CONCLUSIONS Taking the “anticoagulation-bleeding” as the starting point， the clinical pharmacists develop individualized medication plans for patients so as to ensure the safety and effectiveness of medication in the patient by providing pharmaceutical care， such as analyzing the causal relationship between breast cancer treatment-related drugs and PTE， assessing the risk of bleeding and thrombus recurrence， and monitoring patients’ bleeding symptoms and signs and coagulation indicators.

Objective To investigate an automated pretreatment technology for detecting levels of free silica in workplace dust. Methods An fully automated pretreatment workstation for detecting free silica levels in workplace dust was developed by integrating graphite-controlled digestion temperature, online-controlled dilution of digestion solutions, and filtration endpoint recognition based on monitoring technology, combined with multi-channel synchronous measurements. Results The fully automatic pretreatment workstation was used to digest and filter 14 standard samples of free silica produced by three institutions, and then detected by pyrophosphate method. The result range of high-, medium-, and low-level free silica standard samples detection was 66.5%-84.8%, 40.0%-44.5%, and 2.1%-24.8%, respectively. The mean relative standard deviations were 3.9%, 1.4% and 1.5%. Conclusion The fully automated pretreatment workstation produced results that met relevant requirements. It can effectively replace the manual digestion and filtration steps of the pyrophosphate method to measure free silica levels in workplace dust and enable rapid detection of free silica in dust samples.

Objective To investigate the association between the index finger and ring finger length ratio (2D ∶ 4D) and of four loci (rs6461992‚ rs6968828‚ rs7801581‚ rs17427875) polymorphism of homeobox (HOX) A11 gene among Ningxia college students. Methods Digit camera was used to collect frontal hand photos of 667 Han college students (348 males and 319 females) from Ningxia province; Image analysis software was used to mark the anatomical points and measure finger lengths of the index and ring fingers of both hands; multiplex PCR was used to detect each locus polymorphisms of HOXA11 gene; statistical software was used to compare and analyze the differences and associations of 2D ∶4D and gene polymorphisms between different genders.

Objective:To accurately ascertain the whole genome sequencing and the composition of open reading frames (ORFs) of non-replicating Tiantan strain of vaccinia virus (NTV) using next-generation long-read sequencing technology.Methods:NTV, obtained from our laboratory stock, was amplified and purified on chicken embryo fibroblast cells(CEFs), and the full-length genomic nucleic acid of NTV was extracted. The PacBio HiFi sequencing platform was utilized for de novo assembly to obtain the complete genomic sequence of NTV. Using a homology annotation strategy, we identified its ORF composition and compared it with known non-replicating vaccinia virus strains. Results:The total length of NTV′s genome was 171 729 bp, with a GC content of 33%. Its unique inverted terminal repeat (ITR) region comprised hairpin structures, two tandem repeat regions, and three non-repeat regions. NTV contained 166 ORFs, with major differences observed in the ITR and its surrounding regions when compared to MVA-BN and NYVAC. These three strains shared a common set of 138 ORFs. NTV encoded six unique ORFs related to virus evasion of host antiviral response.Conclusions:This study accurately determines the whole genome sequencing and ORFs composition of NTV, and reveals its similarities and differences with other replication-deficient vaccinia virus strains, which pave a way for the development and application of the next generation of monkeypox vaccines and novel viral vectors.

Objective:To study the effects of modified maxillary protraction therapy on the changes in facial soft tissue in patients with maxillary hypoplasia using cephalometric measurements.Methods:26 cases(16 males and 10 females)of Class Ⅲ skeletal malocclu-sion with maxillary hypoplasia during the later period of pubertal peak(CVM Ⅴ to Ⅵ)were included.Treatment was carried out using modified palatal anchorage with a combination of a modified bite-jumping appliance and bilateral maxillary anterior traction.Cephalo-metric measurements were taken before and after treatment using lateral cephalograms,the changes in facial soft tissue-related parame-ters were compared.Results:(1)After treatment,the measurements of soft tissue landmarks in the midfacial region showed a signifi-cant increase(P＜0.05),with the average anterior movement exceeding 3 mm for the nasal tip,subnasale,soft tissue A point and upper lip protrusion point.(2)The changes in the G-Sn-Pos,Ns-Prn-Pos,and S-Ns-Sn were highly significant(P＜0.01),with an average increase in the G-Sn-Pos of 3.23°±3.74°,a decrease in Ns-Prn-Pos of 2.56°±4.99°,and an average increase in S-Ns-Sn of 2.63° ±3.39°.(3)Changes in soft tissue tension and facial height proportion after treatment were not statistically significant(P＞0.05).Con-clusion:The use of a modified pad type intraoral appliance in conjunction with bilateral maxillary anterior traction can effectively pro-mote the improvement of mid facial soft tissue profile in patients with maxillary underdevelopment during the peak growth and develop-ment period,and coordinate the relationship between nasal,lip and chin soft tissue.

Objective To investigate the age-related changes of the mandibular third molar root pulp visibility in individuals in East China,and to explore the feasibility of applying this method to deter-mine whether an individual is 18 years or older.Methods A total of 1 280 oral panoramic images were collected from the 15-30 years old East China population,and the mandibular third molar root pulp visibility in all oral panoramic images was evaluated using OLZE 0-3 four-stage method,and the age distribution of the samples at each stage was analyzed using descriptive statistics.Results Stages 0,1,2 and 3 first appeared in 16.88,19.18,21.91 and 25.44 years for males and in 17.47,20.91,22.01 and 26.01 years for females.In all samples,individuals at stages 1 to 3 were over 18 years old.Conclusion It is feasible to determine whether an individual in East China is 18 years or older based on the mandibular third molar root pulp visibility on oral panoramic images.

Objective To explore the feasibility of individual identification based on the 2D-3D face image superimposition in Han individuals.Methods The 2D video surveillance images(including front,left and right side)and high-precision 3D face models of 10 Han individuals were collected,and Autodesk 3ds Max 2018 software was used to perform perspective matching on the 3D face models,and superimposed them on the 2D images,and the mean values of the distances between corresponding 11 feature points in the 2D-3D face images were calculated.The superimposition of 2D-3D face images from the same individual was defined as the matching group,and the superimposition of 2D-3D face images from different individuals was defined as the non-matching group.Results In general,the average distance ranges of the corresponding feature points between the matching group and the non-matching group did not overlap(P<0.05).Conclusion The non-overlapping mean range preliminarily indicates that the individual identification method based on the overlay comparison of 2D-3D face images described in this paper is feasible for Han individuals.

This paper explored the chemical constituents of Boswellia carterii by column chromatography on silica gel, Sephadex LH-20, ODS column chromatography, and semi-preparative HPLC. The structures of the compounds were identified by physicochemical properties and spectroscopic data such as infrared radiation(IR), ultra violet(UV), mass spectrometry(MS), and nuclear magnetic resonance(NMR). Seven diterpenoids were isolated and purified from n-hexane of B. carterii. The isolates were identified as(1S,3E,7E,11R,12R)-11-hydroxy-1-isopropyl-4,8,12-trimethyl-15-oxabicyclo[10.2.1]pentadeca-3,7-dien-5-one(1),(1R,3S,4R,7E,11E)-4,8,12,15,15-pentamethyl-14-oxabicyclo[11.2.1]hexadeca-7,11-dien-4-ol(2), incensole(3),(-)-(R)-nephthenol(4), euphraticanoid F(5), dilospirane B(6), and dictyotin C(7). Among them, compounds 1 and 2 were new and their absolute configurations were determined by comparison of the calculated and experimental electronic circular dichroisms(ECDs). Compounds 6 and 7 were obtained from B. carterii for the first time.
