Objective To investigate the problems existing in hospital transfusion records,analyze unreasonable factors,and improve the quality of blood transfusion.Methods Investigation of our hospital from January 2016 to January 2017 with blood transfusion medical records,according to hospitalization number,900 cases were selected,using random number table.Investigating blood transfusion records on each record integrity,according toGuidelines for Surgical and Traumatic Blood Transfusion and Internal medicine transfusion guide in clinical blood transfusion technical specifications.The common blood components such as red blood cells,plasma and cryoprecipitate infusion and rationality evaluation.Results There were 583 surgical departments and 557 non-surgical departments.There was a significant difference between the surgical department and the non-surgical department.The reasonable rate of non-operation department was higher than that of the operation department (x2 =7.723,P=0.021).The rational rate of the department was 93.8％,while the operation department was only 88.0％;900 blood transfusion records of four kinds of blood components of the rationality of the difference was statistically significant (x2=214.767,P＜0.001).Non-surgical department of erythrocyte,plasma,cold precipitate reasonable rate than the surgical department;900 medical records in 55 records failed,mainly after the assessment of incomplete blood transfusion,no recorded blood transfusion reaction.There were significant differences in the failure rate between the surgical department and the non-surgical department (x2 =4.613,P=0.032).Conclusion Some physicians transfusion indications,for evaluation before and after blood transfusion blood insufficient attention to curative effect evaluation,blood transfusion is not reasonable,and in the operation department,do not take the blood transfusion medical record writing,hospitals should strengthen the blood transfusion blood transfusion continuously improve the scientific and normative management.

Objective:To investigate the relationship between serum procollagen Ⅲ amino terminal peptide (PIIINP), collagen I carboxyl terminal cross-linking peptide (CTXI), high-sensitivity C-reactive protein (hs-CRP) and cardiac magnetic resonance (CMR) T 1 mapping value in patients with lone atrial fibrillation (AF). Methods:Fifty-five patients with lone AF in Beijing Anzhen Hospital from July 2017 to June 2018 were prospectively enrolled. Another 20 healthy volunteers were examined at the same time to provide normal reference range. All patients completed PIIINP, CTXI, hs-CRP and CMR examination within one week. CMR examination including cine, pre-contrast T 1 mapping, and late gadolinium enhancement sequences. We used t test, Mann-Whitney U test or chi square test to compare the difference of the above indexes between AF patients and the control group. Spearman correlation analysis was used to determine the associations between left ventricular native T 1 value and blood biomarker in AF patients. Results:All the patients were paroxysmal AF with an average age of (48±10) years, of which 46 (83.6%) were male. The PIIINP, CTXI, hs-CRP, left ventricular native T 1 value of AF patients were 5.83 (3.52, 12.40) ng/ml, 4.63 (3.31, 6.82) μg/ml, 3.41 (1.72, 6.61) mg/L and (1 261±23) ms, respectively, which all significant higher than those in healthy subjects (all P<0.05). The native T 1 value of left ventricular myocardium was positively correlated with PIIINP ( r=0.492, P<0.05) and hs-CRP ( r=0.516, P<0.05), but not with CTXI ( r=0.021, P>0.05). Conclusions:The PIIINP, CTXI and hs-CRP increased in patients with lone AF, PIIINP and hs-CRP were correlated with elevated native T 1 value of left ventricular myocardium.

Objective To observe the short- and long-term efficacies of acupuncture in treating metabolic syndrome (MS). Method A hundred MS patients were randomized into an acupuncture group and a Western medication group. In addition to basic treatment, acupuncture was used in the acupuncture group, while Western medication was adopted in the Western medication group. The fasting plasma glucose (FPG), high-density lipoprotein (HDL), insulin (INS), triglyceride (TG), blood pressure (BP), weight circumference (WC), body mass index (BMI), and MS score were evaluated before and after treatment, and a month and 3 months after the treatment. Result There was no significant difference in comparing the short-term therapeutic efficacy between the two groups after treatment, while the long-term therapeutic efficacy of the acupuncture group was superior to that of the Western medication group (P<0.01); the FPG, INS, TG, HDL, BP, and MS score were significantly improved after treatment and a month after the treatment in both groups (P<0.01); the acupuncture group had significant improvements in WC and BMI after treatment and a month after the treatment (P<0.01), significantly superior to the Western medication group (P<0.01); the acupuncture group showed marked improvement in INS, HDL, WC, and BMI 3 months after the treatment (P<0.01), significantly superior to the Western medication group (P<0.01,P<0.05). Conclusion Acupuncture can produce a similar short-term but a better long-term therapeutic efficacy compared to Western medication. Hence, acupuncture can be taken as an assistant intervention for MS.

The medicinal fungi, which are of great importance in traditional medicine, are facing the problems of wild resources scarcity and low concentration of bioactive compounds. Velvet family and LaeA global regulator play a vital role in secondary metabolism and developmental programs, which are found in a wide variety of fungi ranging from Chytridiomycota to Basidiomycota. This review elaborates the structures and functions between Velvet family and LaeA protein. The Velvet family which shares the Velvet protein domain, including VeA (Velvet), VelB (Velvet like B), VosA (viability of spores A) and VelC (Velvet like C), acts on the regulation function is secondary metabolism and developmental programs such as asexual and sexual development. Furthermore, the function is affected by environmental factors such as light and temperature. LaeA protein which owns S-adenosylmethionine-dependent methyltransferase domain, coordinately regulates development and secondary metabolism by regulating and modifying the Velvet proteins. The regulation of LaeA is mediated by light receptor proteins. Therefore, clarifying the mechanism of Velvet and LaeA proteins in medicinal fungi will pave the way for nurturing medicinal fungi and improving production of bioactive compounds.

Objective:To discuss the clinical efficacy and plausible mechanism of Tiao Yang Qu Xie(regulating Yang to eliminate pathogenic factors)needling method plus paroxetine in treating mild-to-moderate depression. Methods:Sixty-six patients with mild-to-moderate depression were divided into an observation group and a control group using the random number table method,each consisting of 33 cases.Another 25 healthy subjects were recruited as a healthy group.The control group took oral paroxetine tablets for treatment,and the observation group received additional acupuncture treatment 3 times weekly.Both groups underwent 4-week treatment.Before treatment,after 2-week and 4-week treatment,and 2 weeks after treatment(follow-up),the patients were assessed using the Hamilton depression scale-17-item(HAMD-17),self-rating depression scale(SDS),self-rating anxiety scale(SAS),and traditional Chinese medicine(TCM)pattern element identification scale for depression.The two groups each randomly contributed 25 cases to detect the protein content of brain-derived neurotrophic factor(BDNF)before treatment and after 4-week treatment,and compared with the healthy group. Results:After 2-week treatment,the markedly effective and total effective rates were significantly higher in the observation group than in the control group(P<0.05);after 4-week treatment,the observation group significantly surpassed the control group in comparing the markedly effective rate(P<0.05).After 2 and 4 weeks of treatment and at the follow-up,the HAMD-17 total score and sleep disorder factor score were lower in the observation group than in the control group(P<0.05);the anxiety-somatic score was lower in the observation group than in the control group after 2-week treatment(P<0.05).After 2 and 4 weeks of treatment and at the follow-up,the observation group was lower than the control group in comparing the scores of SDS,SAS,and TCM pattern element identification scale for depression(P<0.05).After 4-week treatment,the observation group had an increased serum BDNF protein content,higher than that in the control group(P<0.05)and had no significant difference compared to the healthy group(P>0.05). Conclusion:Compared to the use of oral paroxetine alone,acupuncture plus paroxetine can produce more significant efficacy in treating mild-to-moderate depression and act faster in improving sleep disorder and anxiety-somatic symptoms;increasing the serum BDNF protein content may be a part of the mechanism underlying its antidepressant actions.

Objective:To apply multiple mandibular anatomical landmark points to establish the mandibular median sagittal plane to find and establish the ideal median sagittal plane of the mandible that is suitable for clinical diagnosis and treatment.Methods:The maxillofacial spiral CT data of 30 normal maxillofacial patients in the Western Theater General Hospital were collected, and the 3D cranial model was reconstructed by using Mimics Research 21.0 software to select different anatomical landmarks to establish multiple mandibular MSPs, and with the whole cranial MSP as a reference, the different MSPs were respectively used as the mirror planes to establish a mirror model. The overlap of the original model and the mirror model were compared qualitatively and quantitatively by the overlap three-dimensional color illustration of 3-Matic software and Friedman′s test, respectively, to evaluate the application effect of different planes as mandibular MSPs.Results:There was a statistically significant degree of overlap between the mandibular mirror model and the original model with the whole head MSP and the different mandibular MSPs as mirror planes, respectively (χ 2=12.34, P<0.05). The mirror model of plane Mf-Go-Sim had the smallest overlap with the original model 0.07 (0.04, 0.18) mm; plane N-ANS-PNS was the second smallest 0.14 (0.09, 0.58) mm; the difference in overlap of plane ANS-SBWG-Mp 0.12 (0.04, 0.40) mm; the difference in overlap of plane Me-B-Sim 0.19 (0.09, 0.44) mm; the difference in overlap of plane Po-B-Go 0.18 (0.06, 0.45) mm. Conclusions:Whole-head MSP cannot completely replace mandibular MSP; plane Mf-Go-Sim can be the ideal MSP for the mandible in clinical applications.

Objective To find out the prevalence of antiretroviral therapy(ART)drugs among treponema pallidum(TP)antibody(anti-TP)positive blood donors in Shenzhen,and to assess the blood safety risks brought about by the new trends of human immunodeficiency virus(HIV)diagnosis and treatment.Methods A stratified random sampling method was used to select 60 repeat blood donors(negative control group)who passed blood screening in Shenzhen from March 2019 to January 2023,and 3 people who regularly took known ART drugs were named positive control group,358 anti-TP positive/anti-HIV negative blood do-nors were named experimental group 1,20 anti-TP positive/anti-HIV positive blood donors were named ex-perimental group 2.The liquid chromatography-mass spectrometry(HPLC-MS/MS)was applied to detect the concentration of 8 ART drugs in plasma samples of each group,and the use of ART drugs was analyzed.Re-sults After the positive control group's plasma was diluted with a 1:6 dilution mixture,the ART drugs could still be detected.The positive mixed plasma samples of 1:6 people in Group 1 and Group 2 were split and validation,one ART drug positive sample was detected in Group 2,which was positive for anti-HIV,pro-tein immunoblotting,and HIV RNA.The detection rate of ART drugs in anti-TP positive blood donors was 0.26％,0.00％in Group 1 and 4.00％in Group 2.Conclusion The use of ART drugs has been found among anti-TP positive blood donors in Shenzhen,and people with HIV infection and high-risk sexual behavior are more likely to use antiretroviral drugs.

【Objective】 To analyze the results of different methods for reactive samples screened by the enzyme linked immunosorbent assay (ELISA) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in blood donors. 【Methods】 From March to April 2020, a total of 8 632 blood samples in Shenzhen were screened for SARS-CoV-2 total antibodies (TAb, including IgG, IgM, IgA) in plasma using ELISA(PC group), the antibody reactivity samples and their follow up plasma samples (FC group), and samples of disease control group(DC group) from January to April 2020 were detected using the following methods: 1) ELISA method for detecting IgG, IgM, and (or without detection) TAb; 2) pseudovirus neutralizing antibody test(pVNT); 3) western blot (WB) of SARS-CoV-2 antibody. The negative control group(NC group) from February to April 2020 performed ELISA and WB testing. 【Results】 Among the 34 total antibody positive samples, 2 were positive for pVNT test, and the total antibody, IgG and WB in the initial screening and tracking testing were positive. Thereafter, it was determined to be confirmed positive. The other 2 cases were positive for pVNT test, while the samples with positive WB results were in the follow-up stage. The TAb, IgG, and pVNT results did not conform to the dynamic evolution of antibodies, and cannot be determined as confirmed positive. 【Conclusion】 The infection status of antibody reactivity samples screened by SARS-CoV-2 ELISA can be judged by the logic of pVNT, WB and the dynamic change of antibody.

Tanshinones are a class of bioactive components in the traditional Chinese medicine , and their biosynthesis and regulation have been widely studied. Current studies show that basic leucine zipper (bZIP) proteins regulate plant secondary metabolism, growth and developmental processes. However, the bZIP transcription factors involved in tanshinone biosynthesis are unknown. Here, we conducted the first genome-wide survey of the bZIP gene family and analyzed the phylogeny, gene structure, additional conserved motifs and alternative splicing events in A total of 70 SmbZIP transcription factors were identified and categorized into 11 subgroups based on their phylogenetic relationships with those in . Moreover, seventeen genes underwent alternative splicing events. According to the transcriptomic data, the genes that were highly expressed in the Danshen root and periderm were selected. Based on the prediction of bZIP binding sites in the promoters and the co-expression analysis and co-induction patterns in response to Ag treatment quantitative real-time polymerase chain reaction (qRT-PCR), we concluded that and potentially participate in the regulation of tanshinone biosynthesis. These results provide a foundation for further functional characterization of the candidate genes, which have the potential to increase tanshinone production.
