ABSTRACT

With the continuous development of traditional Chinese medicine (TCM), the requirement for the quality of Chinese medicines has become increasingly higher since they have been widely used in clinical practice. Chinese medicinal materials are the material basis for the inheritance and development of TCM, and their quality directly affects the clinical efficacy. Studying the quality of Chinese medicinal materials is the key to ensure the quality and realize the large-scale application. As one of rare Chinese medicinal materials, Cistanches Herba has the functions of tonifying kidney yang, invigorating blood and essence, moistening intestines to relieve constipation. High-quality Cistanches Herba is characterized by glossy appearance, high density, fleshy and soft texture, and sweet taste. With the reduction of wild resources, the products from cultivated Cistanche deserticola or C. tubulosa become dominant on the market of Cistanches Herba. The cultivation areas are widely distributed, mainly concentrated in Gansu, Inner Mongolia, and Xinjiang. However, the cultivated products have varied quality due to the differences in germplasm, producing region, cultivation method, harvesting, and processing. According to the theories of quality evaluation based on morphological characteristics and excellent appearance indicating high quality, this paper reviewed the literature on the quality evaluation, growth, development, and processing of Cistanches Herba in the last decade to explore the main factors (genetic characteristics, environmental conditions, and harvesting and processing factors) affecting the quality of Cistanches Herba. The review aims to explore the factors for the high quality and provide a reference for the producing region screening, directional cultivation, and production of Cistanches Herba.

ABSTRACT

At present, the research of biological living materials mainly focuses on applications in vitro, such as using a single bacterial strain to produce biofilm and water plastics. However, due to the small volume of a single strain, it is easy to escape when used in vivo, resulting in poor retention. In order to solve this problem, this study used the surface display system (Neae) of Escherichia coli to display SpyTag and SpyCatcher on the surface of two strains, respectively, and constructed a double bacteria "lock-key" type biological living material production system. Through this force, the two strains are cross-linked in situ to form a grid-like aggregate, which can stay in the intestinal tract for a longer time. The in vitro experiment results showed that the two strains would deposit after mixing for several minutes. In addition, confocal imaging and microfluidic platform results further proved the adhesion effect of the dual bacteria system in the flow state. Finally, in order to verify the feasibility of the dual bacteria system in vivo, mice were orally administrated by bacteria A (p15A-Neae-SpyTag/sfGFP) and bacteria B (p15A-Neae-SpyCatcher/mCherry) for three consecutive days, and then intestinal tissues were collected for frozen section staining. The in vivo results showed that the two bacteria system could be more detained in the intestinal tract of mice compared with the non-combined strains, which laid a foundation for further application of biological living materials in vivo.

ABSTRACT

Objective:To analyze high-risk behaviors related to HIV infection in men who have sex with men (MSM) recruited by different methods in Zhenjiang city, and to provide a reference for precise prevention and control of acquired immunodeficiency syndrome (AIDS) .Methods:From April to June in 2020, MSM in Zhenjiang city were recruited as research subjects through the center for disease control and prevention (CDC) voluntary counseling and testing (VCT) clinic and community-based organizations (CBOs) . Information such as demographic characteristics, drug abuse, HIV testing history and high-risk sexual behavior were collected through a unified questionnaire survey. Chi-square test or Fisher′s exact test was used to analyze differences in relevant characteristics of MSM recruited by different methods.Results:A total of 641 MSM were recruited by the two methods, including 442 (68.95%) recruited from CBOs and 199 (31.05%) from CDC; the proportion of MSM aged under 20 years was significantly higher in the CBO group (6.56%) than in the CDC group (1.01%, χ2 = 9.20, P = 0.002) ; the proportions of MSM receiving health education information on potential hazards of drug use from professional health institutions and new network media were significantly higher in the CDC group (7.54% [15/199], 16.58% [33/199], respectively) than in the CBO group (3.39% [15/442], χ2 = 5.28, P = 0.022; 9.50% [42/442], χ2 = 6.66, P = 0.010) . In terms of characteristics of sexual behavior, the CBO group showed significantly increased proportions of individuals having group sex (25.21%, 30 cases) and those having unprotected sexual intercourse with women (47.51%, 210 cases) compared with the CDC group (7.50% [6 cases], χ2 = 10.13, P = 0.001; 27.64% [55 cases], χ2 = 22.35, P < 0.001, respectively) , but significantly decreased proportions of heterosexuals (2.04%, 9 cases) , individuals unknowing about the HIV status of sexual partners (22.40%, 99 cases) and those having unprotected anal sex with men (39.82%, 176 cases) compared with the CDC group (6.53% [13 cases], χ2 = 8.37, P = 0.004; 39.70% [79 cases], χ2 = 20.48, P < 0.001; 57.29% [114 cases], χ2 = 16.90, P < 0.001, respectively) . Compared with the CDC group, the CBO group showed significantly decreased proportions of individuals ever having an HIV test (74.43% [329 cases] vs. 80.90% [161 cases], χ2 = 3.19, P = 0.074) and those getting the latest HIV test from CDC (23.10% [76 cases] vs. 57.14% [92 cases], χ2 = 99.41, P < 0.001) , as well as decreased prevalence of HIV infection (5.20% [23 cases] vs. 13.07% [26 cases], χ2 = 21.85, P < 0.001) . Conclusions:The MSM recruited from CBO and CDC are complementary in terms of demographics and behaviors, and can represent the general MSM population. Specific prevention and control measures for AIDS should be taken according to different characteristics of the MSM population.

ABSTRACT

ObjectiveTo conduct genetic variation analysis of 11 cultivars and 7 wild populations of Angelica sinensis in Gansu province based on the chloroplast gene (cp DNA), and provide references for germplasm identification and breeding of new cultivars of A. sinensis. MethodThree pairs of cp DNA primers were used for polymerase chain reaction (PCR) amplification and sequencing of A. sinensis samples. MegaX was used to perform statistics on sequence characteristics and calculate mean genetic distances among A. sinensis populations. Unweighted pair-group method with arithmetic means (UPGMA) clustering tree based on genetic distance was constructed by NTSYS 2.10e. DanSP v6 was used to calculate sequence polymorphism and Tajima's D of A. sinensis. PERMUT was used to calculate the population structure of A. sinensis. Arlequin v3.5 was used to perform molecular variation analysis, and PopART1.7 was used to construct TCS haplotype network. ResultThree pairs of cp DNA primers were amplified, sequenced, compared, and combined to give a sequence length of 1 759 bp. One variable site was detected in the wild A. sinensis and 480 variable sites were detected in the cultivated A. sinensis, including 97 singleton variable sites, 383 parsimony informative sites, and 152 insertion-deletion sites. In the three regions of matK, psbA-trnH, and rbcL of cp DNA in the wild and cultivated A. sinensis, matK was the region with the highest polymorphism. Tajima’s D of all the combined sequences of A. sinensis were not significantly negative, but psbA-trnH and rbcL genes of the cultivated A. sinensis were significantly negative, indicating that the A. sinensis followed neutral evolution on a whole, while psbA-trnH and rbcL genes had undergone selection. The degree of genetic differentiation (Fst=0) among wild populations was lower than that among cultivated populations (Fst=0.114 19, P<0.05). The degree of genetic differentiation between wild and cultivated A. sinensis was relatively high (Fst=0.942 55, P<0.01). Genetic variation in the cultivated A. sinensis was mainly found within the populations (89%). UPGMA cluster tree based on genetic distance showed that the wild A. sinensis and the cultivated A. sinensis were clustered into one branch, respectively, with a distant genetic relationship, and the population 3 in the cultivated A. sinensis was far from other cultivated populations. The TCS haplotype network consisted of 15 haplotypes and 4 unknown haplotypes, which was divided into 3 parts, with a large number of variations among each part. Shared haplotypes were only found in the wild or cultivated groups, and there were no shared haplotypes between groups. ConclusionThe genetic diversity of A. sinensis was low at species level, and the population diversity of the wild was lower than that of the cultivated. The degree of genetic differentiation between the wild and the cultivated A. sinensis was high, but that in the wild and the cultivated populations were low. Genetic variation in the cultivated A. sinensis was mainly found within populations.

ABSTRACT

ObjectiveTo analyze the sequence variation and genetic diversity of 47 Isatis indigotica germplasm materials, and carry out the study on the genetic differentiation and structure. MethodGenomic DNA of 47 I. indigotica germplasm materials were extracted by kit extraction method. Two chloroplast DNA (cp DNA) sequences and five inter-simple sequence repeat (ISSR) primers were used for amplification and sequencing. Chromas, Mega 7.0, DanSP5, and GenALEx were used to calibrate, splice, and analyze the sequence characteristics. PERMUT and PopGen 1.31 were used to analyze the genetic diversity parameters and genetic structure, and NTSYS was used to obtain the unweighted pair-group method with arithmetic means(UPGMA) clustering tree plot of 47 I. indigotica germplasm materials. ResultA total of 129 samples from 47 I. indigotica germplasm materials were successfully amplified and sequenced. The length of 2 cp DNA sequences after spliced was 1 412 bp, and there were 377 polymorphic variation loci, and 36 haplotypes. Fu and Li's D* test was significant (P<0.01). The values of Pi, HS, and HT based on cp DNA were 0.119 89, 0.787, and 0.891, respectively. The genetic differentiation coefficients of gene differentiation coefficient(Gst), nucleotide differentiation coefficient(Nst), and fixation index(Fst) were 0.117, 0.468, and 0.488, respectively, and the gene flow (Nm) was 0.615. The mean values of PPB, Shannon information diversity index(I), Nei's genetic diversity index(H), and Gst based on ISSR were 78.85%, 0.334 8, 0.218 6, and 0.754 4, respectively, and the Nm value was 0.162 8. ConclusionI. indigotica has high genetic diversity and abundant haplotypes at the species level, with abundant haplotypes. Genetic differentiation among different germplasm materials is obvious, and gene exchange is not frequent. Genetic variation mainly exists among populations. The population has accumulated various low-frequency gene mutations recently, suggesting that it has experienced significant regional expansion in the history.

ABSTRACT

In recent years,scientific researchers have increasingly become interested in noninvasive sampling methods for therapeutic drug monitoring and disease diagnosis.As a result,dried saliva spot(DSS),which is a sampling technique for collecting dried saliva samples,has been widely used as an alternative matrix to serum for the detection of target molecules.Coupling the DSS method with a highly sensitive detection instrument improves the efficiency of the preparation and analysis of biological samples.Furthermore,dried blood spots,dried plasma spots,and dried matrix spots,which are similar to those of the DSS method,are discussed.Compared with alternative biological fluids used in dried spot methods,including serum,tears,urine,and plasma,saliva has the advantage of convenience in terms of sample collection from children or persons with disabilities.This review aims to provide integral strategies and guidelines for dried spot methods to analyze biological samples by illustrating several dried spot methods.Herein,we summarize recent advancements in DSS methods from June 2014 to March 2021 and discuss the advantages and disadvantages of the key aspects of this method,including sample preparation and method validation.Finally,we outline the challenges and prospects of such methods in practical applications.

ABSTRACT

Recently, unsupervised deep learning methods have shown great potential in image processing. Compared with a large-amount demand for paired training data of supervised methods with a specific task, unsupervised methods can learn a universal and explicit prior information on data distribution and integrate it into the reconstruction process. Therefore, it can be used in various image reconstruction environments without showing degraded performance. The importance of unsupervised learning in MRI reconstruction appears to be growing. Nevertheless, the establishment of prior formulation in unsupervised deep learning varies a lot depending on mathematical approximation and network architectures. In this work, we summarized basic concepts of unsupervised deep learning comprehensively and compared performances of several state-of-the-art unsupervised learning methods for MRI reconstruction.

ABSTRACT

OBJECTIVE@#To compare the effectiveness and sensitivity of entropy and regional homogeneity (ReHo) for identifying irritable bowel syndrome (IBS) based on functional magnetic resonance imaging (fMRI).@*METHODS@#Voxel-based approximate entropy (ApEn) was calculated based on findings of resting fMRI of 54 patients with IBS and 54 healthy control subjects. Feature selection was performed using independent sample -test, and support vector machine was then used to classify and identify different groups. The classification performance obtained from ApEn was compared with that from ReHo.@*RESULTS@#Significant differences between the two groups were found in the left triangle part of inferior prefrontal gyrus, right angular gyrus of the inferior parietal lobule, left inferior temporal gyrus, left middle temporal gyrus, left lingual gyrus, bilateral middle occipital gyrus and bilateral superior occipital gyrus for ReHo ( < 0.05), and in the bilateral postcentral gyrus, right precentral gyrus, right inferior temporal gyrus, bilateral middle temporal gyrus and left superior occipital gyrus for ApEn ( < 0.05). ApEn consistently showed better performance than ReHo regardless of the variations in the number of features. The classification accuracy, specificity and sensitivity of ApEn were 93.5185%, 90.7407% and 96.2963%, respectively, as compared with 86.1111%, 85.1852% and 87.037% of ReHo.@*CONCLUSIONS@#Entropy analysis based on fMRI can be more sensitive and effective than ReHo for identification of IBS.

ABSTRACT

Objective The prognostic role of PD-L1 expression in surgically resected lung adenocarcinoma(ADC)remains controversial. The aim of present study was to investigate the prognostic value of PD-L1 combined with CD8 +TILs expression in pa-tients with resectable lung adenocarcinoma. Methods A total of 104 patients with lung adenocarcinoma who underwent radical resec-tion were enrolled at the Affiliated Tumor Hospital of Harbin Medical University from January 2009 to December 2012. Immunohisto-chemistry was used to detect the expression of PD-L1 and CD8 +TILs in primary tumor specimens. Its clinical pathological factors and its relationship with prognosis were statistical analysis. Results The positive expression rate of PD -L1 in tumor cells was 38. 5% (40/104),and the positive rate of CD8 +TILs was 44. 2% (46/104). There was a significant correlation between the expres-sion of CD8 +TILs and TNM stages of patients with resectable ADC. The Kaplan-Meier survival analysis showed that low expression of PD-L1 and high expression of CD8 +TILs were significantly associated with disease -free survival ( DFS) and overall survival ( OS),and could be used as an independent predictors for predicting prognosis of patients with resectable ADC. Conclusion The ex-pression of PD-L1 and CD8 +TILs in the postoperative specimens can help to judge the prognosis of patients. This study has certain significance for immunotherapy of PD-1/PD-L1 pathway in patients with surgically resected ADC.

ABSTRACT

OBJECTIVE@#To establish a fast adaptive active contour model based on local gray difference for parotid duct image segmentation.@*METHODS@#On the basis of the LBF model, we added the mean difference of the local gray scale inside and outside the contour as the energy term of the driving evolution curve, and the local gray-scale variance difference was used to replace and as the control term of the energy parameter value. Two local similarity factors of different neighborhood sizes were introduced to correct the effects of image gray unevenness and boundary blur to improve the segmentation efficiency.@*RESULTS@#During image segmentation, this algorithm allowed for adaptive adjustment of the evolution direction, velocity and the energy weight of the internal and external regions according to the difference of gray mean and variance between the internal and external regions. This algorithm was also capable of detecting the actual boundary in a complex gradient boundary region, thus enabling the evolution curve to approach the target boundary quickly and accurately.@*CONCLUSIONS@#The proposed algorithm is superior to the existing segmentation algorithms and allows fast and accurate segmentation of the parotid duct with well-preserved image details.

ABSTRACT

Objective@#To explore the clinical value of endoscopic interventional therapy for locally recurrent primary lung adenoid cystic carcinoma (ACC).@*Methods@#The clinical data of 42 patients with locally recurrent ACC were retrospectively analyzed, and the differences of tracheal and bronchial diameter, airway scoring grade and airway obstruction degree before and after treatment were compared among three treatment methods: bronchoscopic interventional therapy + palliative radiotherapy, interventional therapy alone, and non-interventional therapy. Log rank test and Cox proportional risk model multi-factor analysis were used to determine the prognostic factors of ACC patients with local recurrence, and the long-term effect of bronchoscopic interventional therapy on ACC with local recurrence was determined.@*Results@#The median overall survival of 42 patients was 59 months and 5-year survival rate was 54.2%.Univariate analysis showed that vascularized cancer, pleural invasion, pulmonary atelectasis, incisal margin, microscopic classification, tumor diameter, initial TNM stage, ki-67 index, and treatment after local recurrence were associated with long-term survival of ACC patients with local recurrence (all P<0.05). Cox multivariate regression analysis showed that margin status (RR=0.272, P=0.011), tumor diameter (RR=2.586, P=0.005), initial TNM staging (RR=0.369, P=0.035), ki-67 index (RR=3.569, P<0.001), and treatment methods after local recurrence (RR=0.126, P<0.001) were independent factors influencing the prognosis of ACC patients with local recurrence. After three months of treatment, the tracheal bronchus diameters, rating of shortness of breath, and degree of airway obstruction were all improved significantly (all P<0.05), both in the interventional therapy + palliative radiotherapy group [(14.5±2.8 mm, 0.86±0.45, (14.50±10.67)%, respectively], and the interventional therapy alone group [(13.7±2.3) mm, 0.97±0.25, (15.38±12.02)%, respectively]. Meanwhile, the difference before and after non-interventional therapy was not statistically significant (all P>0.05). 5-year overall survival rates were 55.8%, 46.6% and 42.6% for patients undergoing interventional therapy+ palliative radiotherapy, interventional therapy alone, and non-interventional therapy after recurrence, with statistically significant differences (P=0.015). Patients underwent bronchial endoscopic interventional therapy and palliative radiotherapy had the best efficacy of treatment.@*Conclusion@#Endoscopic interventional therapy plus palliative radiotherapy is an effective local palliative treatment for locally recurrent ACC patients, which can rapidly relieve airway stenosis, improve the quality of life of patients and prolong the survival time of patients.

ABSTRACT

OBJECTIVE:To explore the general rules and characteristics of ADR/ADE induced by Monosialotetrahexosylgan-glioside sodium injection(GM1)as well as related risk factors,and to provide reference for safe,effective and economical drug use in clinic. METHODS:By hospital LAN,non-interventional centralized monitoring was conducted among patients receiving GM1 in our hospital from Jan.-Jun. 2016.The patients'information,drug use,ADR/ADE and clinical outcomes were analyzed sta-tistically. RESULTS:A total of 621 patients were involved,including 393 male patients and 228 female patients with male-to-fe-male ratio of 1.72:1.The patients who were more than 61 years old were the majority(60.39%).GM1 was mainly used in neurolo-gy department(71.18%),emergency department(6.28%),neurosurgery department(6.12%),general practice department(4.67%)and TCM rehabilitation department(4.03%). Among them,there were 28 ADR/ADE cases,with incidence of 4.51%. Among 42 patients with off-indication,3 cases had ADR/ADE,with incidence of 7.14%. Meanwhile,the constituent ratio of ADR/ADE in male(67.86%)was higher than that in female(32.14%). Twenty-two cases received more than three or more drugs(78.57%). Furthermore,ADR/ADE mainly manifested as systemic damage(35.71%),lesion of skin and its appendants (28.57%). Among 579 patients met drug use with indication,there were 165 cured cases,405 recovered cases and 9 uncured cases. In addition,the average expenditure of using GM1 was 5 108.08 yuan,accounting for 9.07% of total hospitalization cost and 23.33% of total drug cost. CONCLUSIONS:It is necessary to strengthen rational drug use and monitoring of GM1,under-stand the regularity and characteristics of GM1-induced ADR/ADE,so as to reduce the incidence of ADR/ADE and ensure safe, effective and economical drug use.
