ABSTRACT

In this study, we designed and synthesized 12 novel aloperine derivatives with different core structures. Among them, compound 3 with a ten-membered ring core was obtained through a special ring expansion reaction after γ-H Huffman elimination of quaternary ammonium salt, and the structure was verified by X-single crystal diffraction. Furthermore, their antiviral activity against human β-coronavirus HCoV-OC43 was evaluated by CCK-8 assay. Quaternary ammonium salt 2a and 3 had a good inhibitory effect against HCoV-OC43, and 2a had the highest anti-HCoV-OC43 activity with an EC50 values of 3.77 μmol·L-1 and a SI value of over 53.1. Schrӧdinger molecular docking results showed that both 2a and 3 might display their anti-HCoV-OC43 activity by directly acting on host TMPRSS2 and SR-B1. The results expanded the structural types of endocyclic aloperine and the function against coronavirus, and provided useful scientific data for the development of pharmaceutical applications of these compounds.

ABSTRACT

OBJECTIVE: To observe the correlation between the thickness of superficial fascia at Dazhui (GV14) acupoint and cervical spondylosis, so as to explore the essence of its morphological and structural changes of acupoint sensitivity. METHODS: A retrospective study was conducted. According to the diagnostic criteria of "Guidelines for Diagnosis, Treatment and Rehabilitation of Cervical Spondylosis" (2017), 344 cases of cervical spine magnetic resonance imaging (MRI) examination were included and divided into control group (73 cases) and observation group (271 cases). The control group was healthy population, and the observation group was patients with cervical spondylosis conforming to the diagnostic criteria, including cervical spondylosis of neck type, cervical spondylosis radiculopathy, cervical spondylotic myelopathy, cervical spondylosis of vertebral artery type, and sympathetic cervical spondylosis. According to MRI images of cervical spine, the structure of GV14 acupoint including skin, superficial fascia layer and aponeurosis ligament layer were measured. RESULTS: The acupoint depth and the superficial fascia thickness at GV14 in the observation group were (56.6±8.8) mm and (22.8±7.6) mm, the acupoint depth and the superficial fascia thickness at GV14 were (49.8±7.0) mm and (16.6±6.6)mm in the control group, which were significantly greater in the observation group than in the control group (P<0.01). The superficial fascia thickness at GV14 of cervical spondylotic mye-lopathy, cervical spondylosis of neck type and cervical spondylosis radiculopathy in the observation group was (23.8±8.1)mm, (23.0±7.3)mm and (22.6±6.5)mm, the acupoint depth of GV14 was (58.7±8.8)mm, (56.2±9.1)mm and (55.8±6.4)mm, which were significantly thicker than the superficial fascia thickness and the acupoint depth in the control group (P<0.01). In the observation group,the superficial fascia thickness of GV14 of cervical spondylosis myelopathy was significantly thicker than those of sympathetic cervical spondylosis (17.8±8.1) mm and cervical spondylosis of vertebral artery type (19.9±5.9) mm (P<0.01, P<0.05). In the observation group, the depth of GV14 of cervical spondylosis myelopathy was thicker than that of cervical spondylosis of neck type, cervical spondylosis radiculopathy, sympathetic cervical spondylosis and cervical spondylosis of vertebral artery type(P<0.05,P<0.01); the depth of GV14 of sympathetic cervical spondylosis was thinner than that of cervical spondylosis of neck type and cervical spondylosis radiculopathy (P<0.01). CONCLUSION: The superficial fascia thickness at GV14 was correlated with cervical spondylosis, and it is also related to cervical spondylotic myelopathy, cervical spondylosis of neck type and cervical spondylosis radiculopathy. The morphological and structural changes of GV14 in the state of cervical spondylosis were mainly the thickness of the superficial fascia.

ABSTRACT

【Objective】 To statistically analyze the re-entry test and blood re-donation of HBV, HCV, TP and HIV single-reagent reactive blood donors in Hohhot from 2019 to 2021, so as to demonstrate the rationality, feasibility and necessity of the re-entry strategy of voluntary blood donors in Hohhot, and provide theoretical support for further standardizing of the reentry of blood donors. 【Methods】 A total of 225 samples of blood donors who applied for re-entry in Hohhot from 2019 to 2021 were collected, and HBV, HCV and HIV were tested by two reagent serological tests and nucleic acid tests. TP anti-TP was detected by two reagent serological methods. The test results were all non-reactive and met the requirements of re-entry. The blood donation status of blood donors after re-entry was followed up and analyzed. 【Results】 Among the 225 cases detected for HBV, HCV, TP and HIV from 2019 to 2021 in Hohhot, 178 were qualified for the returning, with a re-entry rate of 79.11%, and 75 donated blood again, with a after re-entry re-donation rate of 42.13%. 【Conclusion】 The strategy of returning for HBV, HCV, TP and HIV single reagent reactive blood donors in Hohhot is effective, and has positive significance for safeguarding the rights and interests of blood donors and alleviating regional blood supply shortages.

ABSTRACT

Particulate matter (PM) is a hazardous airborne pollutant that encompasses all airborne particles with diameters ranging from 0.001 to 100 µm. It is composed of total suspended particles (TSPs), consisting of two main particle sizes: PM10 and PM2.5. PM poses various threats to human health because of its rapid mobility and its ability to spread over a wide area. In particular, it has long-term negative effects on such organs as the lungs and heart. China and South Korea, located in Northeast Asia, are representative of the countries at risk of PM, and their populations live with an awareness that the harms of PM go beyond physical risks. Therefore, based on previous studies, this study classifies the perceived PM risks into physical, psychological, financial, functional, and time risks. It has tried to verify the effect of this risk perception on the behavior intention of Chinese and Koreans and examine the moderating effect according to the difference in nationality. The study's conceptual model was constructed by applying Ajzen's proven theory of planned action. Utilizing AMOS 22.0 and SPSS 22.0, an analysis was performed. Following this analysis, it was determined that there was a significant causal relationship between perceived PM risk and behavioral attitudes, subjective norms, and perceived behavioral control. Additionally, it was discovered that perceived PM risk significantly impacted desire and behavioral intention. These findings demonstrate that when persons are exposed to high concentrations of PM, they perceive a variety of risks that go beyond the merely physical, and they can form different attitudes depending on their nationality. This study greatly contributes to the theoretical and practical implications by presenting more diverse perspectives on PM risk.

ABSTRACT

Parthenium hysterophorus L. is a vigorous plant species with cosmopolitan distribution. It can uptake considerable quantities of heavy metals from the soil and accrue these metals in its different tissue. The use of chelating agent i.e., Ethylenediaminetetraacetic acid (EDTA) can boost up metal uptake capacity. Pot experiment was performed to evaluate phytoextraction potential of P. hysterophorus for lead (Pb) and cadmium (Cd) with and without the aid of EDTA chelator. Shoot length, weight of root and shoot (both fresh and dry), leaves number, and chlorophyll contents of P. hysterophorus got reduced with an increase in metal uptake. The results revealed the highest concentration of Cd in shoot without and with EDTA was 283.6 and 300.1 mg kg-1, correspondingly. Increase in Pb concentration was also boosted up by the EDTA from its maximum concentration in shoot 4.30-9.56 mg kg-1. Generally, Pb and Cd concentrations were greater in shoots of P. hysterophorus than the roots regardless of EDTA in the treatments. EDTA also impacted positively the accumulation of essential ions K+, Na+, and Ca+2 in P. hysterophorus. The capacity of P. hysterophorus to accumulate Pb and Cd found to be increased with EDTA in the soil. Bringing metals level in the soil in accordance to the WHO standards can improve the ecosystem as well as public health.

ABSTRACT

Albeit the efficacy of COVID-19 vaccines in immunocompromised patients is undermined, it is still found beneficial. Patients with cancer have a much lower COVID-19 vaccination rate globally, and the vaccination coverage in breast cancer patients in China remains elusive. A total of 23029 patients with benign breast diseases and breast cancers were included in the study, and the vaccination rates of patients with benign breast tumors and other benign breast diseases, nonmetastatic and metastatic breast cancer were 44.0%, 54.7%, 19.2% and 9.6%, respectively. Breast cancer in situ patients had a similar vaccination rate with patients with benign breast tumors (45.9% vs 44.0%) while those with invasive breast cancer had much lower vaccination rates. The overall vaccination rate remains meager in breast cancer patients, and gap was found in patients with lower clinical stage. Hence vaccination should be further promoted among patients with benign breast diseases and breast cancer.

ABSTRACT

Surgery is recognized as the core treatment for colorectal liver metastasis (CRLM), while its recurrence rate remains relatively high, even for resectable CRLM. This hints that the efficacy of treatment involves not only technological factors of surgery, but also biological behavior of tumor. For resectable CRLM, neoadjuvant therapy is beneficial to eliminate the micro-metastasis, reduce postoperative recurrence rate, screen tumor biological behavior and improve prognosis. However, questions about which kind of CRLM patients fits for neoadjuvant therapy and what regimen should be used are still debatable. This paper reviews stratified management of resectable CRLM, choice of neoadjuvant regimen, especially the application value of targeted therapy, based on the latest guidelines and studies.

ABSTRACT

Objective:To observe the abnormal clinical manifestations of retinal blood vessels and the characteristic image characteristics of optical coherence tomography (OCT) in young myopia.Methods:A case observation study. From July to December 2020, 523 young patients with different myopia refractive powers who were treated in Department of Ophthalmology of The Second Hospital of Hebei Medical University were included in the study. Among them, 277 were males and 246 were females; the median age was 19.0 (5.0) years. All the affected eyes underwent best corrected visual acuity (BCVA), frequency domain OCT (SD-OCT) examination and axial length (AL) measurement. The BCVA examination was performed using the Snellen eye chart. The median myopia refractive power of the affected eye was 5.00 (3.25) D. Among them, low myopia, moderate myopia, and high myopia were 227, 405, and 414 eyes, respectively. The average AL of the affected eye was 25.6±2.8 mm. The frequency domain OCT instrument was used to scan the temporal side of the retina, the upper and lower nasal vascular arches and the macular fovea radially. The images of retinal vascular cysts, microfolds, and lamellar hole were acquired and stored. The prevalence, composition ratio, distribution rule and OCT imaging characteristics of retinal paravascular abnormalities were observed and analyzed. The distribution of paravascular abnormalities in the retina was compared by the χ2 test; the age, refractive power, and AL of different paravascular abnormalities were compared by the K-W rank sum test. Results:Of the 1046 different diopters of myopic eyes, there were 227 eyes in mild myopia, 405 eyes in moderate myopia and 414 eyes in high myopia. Retinal paravascular abnormalities were detected by SD-OCT in 40 eyes (3.8%,40/1046). The prevalence of retinal paravascular abnormalities in moderate myopia was 0.7% (3/405) and high myopia was 8.9% (37/414). No retinal paravascular abnormalities were observed in mild myopia.Retinal paravascular cysts in 40 eyes (3.8%, 40/1046), retinal paravascular microfolds in 28 eyes (2.7%, 28/1046) and retinal paravascular lamellar holes in 13 eyes (1.2%, 13/1046). Of 40 eyes with retinal paravascular abnormalities, retinal paravascular cysts in all 40 eyes (100.0%, 40/40), retinal paravascular microfolds in 28 eyes (70.0%, 28/40) and retinal paravascular lamellar holes in 13 eyes (32.5%, 13/40). Twelve eyes with simple cyst cavity (30.0%, 12/40); 15 eyes were with cyst cavity with micro-wrinkles (37.5%, 15/40); 13 eyes were with cyst cavity, micro-wrinkles and lamellar holes (32.5%, 13/40). The temporal vascular arch retinal paravascular cysts ( χ2=25.664), microfolds ( χ2=14.973), and lamellar holes ( χ2=13.499) were significantly more than those on the nasal side, and the difference was statistically significant ( P <0.001). Conclusions:The total prevalence of retinal paravascular abnormalities in young myopia is 3.8%; it can occur in both moderate and high myopia. The paravascular cyst may be the earliest pathology of paravascular abnormalities in the retina. The three paravascular abnormalities are mostly distributed along the temporal arch of the retina.

ABSTRACT

OBJECTIVE: To explore the efficacy difference of electroacupuncture at lower he-sea point and he-sea matching front-mu points for the treatment of gastroparesis. METHODS: A total of 63 patients with gastroparesis were randomly divided into a lower he point group (group A, 32 cases, 2 cases dropped off) and a he matching mu points group (group B, 31 cases, 1 case dropped off). The group A was treated with electroacupuncture at Zusanli (ST 36), and the group B was treated with electroacupuncture at Zusanli (ST 36) and Zhongwan (CV 12). Both groups were treated with continuous wave (2 Hz in frequency) for 30 min, once a day, 5 times a week for 3 weeks. The gastroparesis cardinal symptom index (GCSI) score, gastric half-emptying time (T1/2) and the 180 min gastric residual rate of the two groups before and after treatment were observed, and the clinical effective rate was compared. RESULTS: After treatment, the total GCSI scores, T1/2 and the 180 min gastric residual rates in both groups were lower than those before treatment (P<0.01), and the 180 min gastric residual rate and T1/2 in the group A were lower than those in the group B (P<0.05). The total effective rate was 93.3% (28/30) in the group A, which was superior to 70.0% (21/30) in the group B (P<0.05). CONCLUSION: Electroacupuncture at lower he-sea point and he-sea matching front-mu points can both be used to treat gastroparesis, but electroacupuncture at Zusanli (ST 36) has a better effect. The acupoints of Zusanli (ST 36) and Zhongwan (CV 12) may have antagonistic effects.

ABSTRACT

Objective@#To discuss the benefit of using transmastoid slotted labyrinthotomy approach (TSLA) and customized electrode for common cavity deformity (CCD) patients, and to evaluate the audiological outcomes.@*Methods@#A retrospective analysis of the intraoperative monitoring data and postoperative auditory outcomes of 10 CCD cases who received cochlear implantation in Beijing Tongren Hospital,Capital Medical University from April 2016 to December 2017, was conducted using TSLA and customized electrod as a test group.At the same time, 10 cases of age and gender matched children with severe or severe sensorineural hearing loss and normal inner ear structures were recorded as a control group. Four questionnaires were collected from the two groupspre-operative, 6 months and 1 year after start-up. The Wilcoxon signed rank sum test was used to compare the scores of different time points. Rank sum test of two independent samples was used to compare the scores between different groups.@*Results@#None of the patients exhibited CSF leakage or facial paralysis after operation. The average impedance of 8 CCD children in the experimental group was below 5 kΩ. The total extraction rate of auditory neural response telemetry (ART) of all stimulating electrodes was 55% (33/60), and the amplitude of the electricity induced complex action potential (ECAP) of electrodes at different positions ranged from 50.69 to 170.3 μV.The average surgical time of the TSLA group was 46.4 min, shorter than the traditional approach.There was significant difference between the scores of pre-operative, 6 months and 1 year after start-up for the TSLA group(categories of auditory performance,CAP: 2.0 (2.0,3.0) vs. 4.0 (3.8,4.0) , Z=-3.109, P=0.002; speech intelligibility rating,SIR: 2.0 (2.0,2.3) vs. 3.0 (2.8,4.0) , Z=-2.952, P=0.003; meaningful use of speech scale,MUSS: 4.0 (3.3,6.0) vs. 9.0 (6.0,11.8) , Z=-3.421, P=0.001; meaningful auditory integration scale, MAIS or infant-toddler and meaningful auditory integration scale, IT-MAIS: 5.5 (3.8,9.0) vs. 15.5 (10.8,18.5) , Z=-3.522, P=0.000 for the latter two).In addition, The scores of the TSLA group were significantly worse than the control group at 6 months and 1 year after start-up.The high-resolution CT scan showed good adhesion of the electrodes without displacementone week and one year after surgery.@*Conclusions@#For CCD patients, TSLA and customized electrode is recommended due to lower surgical difficulty and post-operative risk, shortened surgical time; Intraoperative ART monitoring can be used to determine the integrity of the auditory pathway. Children with common cavity deformity have a longer period of auditory rehabilitation, and the individual differences in speech rehabilitation are significantly different, which is significantly worse than those with normal structure.

ABSTRACT

Programmed cell death protein 1 (PD-1), as a checkpoint of the immune signaling pathway, is a hotspot in the field of immuno-oncology. Its binding with ligand (PD-L1) is an important negative regulatory mechanism. Application of PD-1/PD-L1 inhibitors in treatments of breast cancer is still being explored at present. Fully understanding the mechanism of PD-1/PD-L1 in the microenvironment of breast cancer will help their inhibitors play a full role. This review will start with the discovery of PD-1 and PD-L1, describe their main signaling pathways, introduce the common types and applications of PD-1/PD-L1 inhibitors, especially in breast cancer, summarize the basic research of PD-1 and PD-L1 in breast cancer microenvironment in recent years, and seek new strategies of PD-1/PD-L1 inhibitors in breast cancer treatment.

ABSTRACT

OBJECTIVE: To observe the therapeutic effect of tranquilizing and allaying excitement needling method on insomnia of heart and spleen deficiency and the effect of brain blood flow. METHODS: Sixty cases were randomly divided into a tranquilizing and allaying excitement needling method group (observation group) and an eight confluence points selected group (control group), 30 cases in each group. The observation group was treated by acupuncture at Sishencong (EX-HN 1), Shenmen (HT 7), and Sanyinjiao (SP 6) with tranquilizing and allaying excitement needling method. The control group was treated by acupuncture at Shenmai (BL 62) and Zhaohai (KI 6). Their therapeutic effects and changes of brain blood flow were observed. RESULTS: The total effective rate was 93.3% (28/30) in the observation group which was better than 83.3% (25/30) in the control group (P < 0.05). After treatment, the peak velocity of systolic (Vp) and diastolic blood flow velocity (Vd) of middle cerebral artery, basilar artery and vertebral artery were increased in the both groups (P < 0.01, P < 0.05), with more obvious increase in the observation group (P < 0.01, P < 0.05), except the Vd of left vertebral artery. CONCLUSION: Both the tranquilizing and allaying excitement needling method and the eight confluence points selected needling method can improve the clinical signs and symptoms. Meanwhile, the therapeutic effect of acupuncture is related with improvement of brain blood flow. However, the tranquilizing and allaying excitement needling method has better therapeutic effect on insomnia of heart and spleen deficiency.

ABSTRACT

Having studied white tiger shaking head method described by ancient and modern physicians, and analyzed and compared its manipulation techniques, the authors believe that the core of white tiger shaking head method originating from Zhenjiu Daquan ([Chinese characters: see text] Complete Book of Acupuncture-Moxibustion) by XU Feng lies in the techniques of "squarely withdrawing and circularly inserting" and "shaking and vibrating", and the manipulation factor is "circularly inserting and shaking, and squarely withdrawing and vibrating". Physicians such as WANG Ji (his second method), YANG Ji-zhou, LU Shou-kang and ZHENG Kui-shan inherited and developed white tiger shaking head method. WANG Ji's first method and what LI Chan and modem physicians YANG Zhao-min and LU Shou-yan described do not belong to white tiger shaking head method. The authors have made a new suggestion on standardizing the manipulation of white tiger shaking head method and approached to new ideas on research into standardization of ancient acupuncture.

ABSTRACT

It is important to establish the hospital information system security policies. While these security policies are being established, a comprehensive consideration should be given to the acceptable levels of users, IT supporters and hospital managers. We should have a formal policy designing process that is consistently followed by all security policies. Reasons for establishing the security policies and their coverage and applicable objects should be stated clearly. Besides, each policy should define user's responsibilities and penalties of violation. Every organization will need some key policies, such as of information sources usage, remote access, information protection, perimeter security, and baseline host/device security. Security managing procedures are the mechanisms to enforce the policies. An incident-handling procedure is the most important security managing procedure for all organizations.

ABSTRACT

Objective To study the role of cutaneous nerve and protease activated receptor 2 (PAR2)in the development of pruritus in atopic dermatitis(AD).Methods Dermal sheets were prepared from chronically pruritic skin lesions of 7 patients with AD,as well as from the normal skin of 7 healthy human controls.Double labeled immunofluorescence was performed using mouse anti-protein gene product 9.5(PGP9.5)monoclonal antibody and rabbit anti-substance P(SP)polyclonal antibody to observe the morphological changes in cutaneous nerve fibers,and Image-Pro Plus 6 software was used to semiquantitively assess the length,diameter of nerve fibers,integral optimal density of PAR2 and SP in dermal sheets.Results Immunofluoresence double staining showed that PAR2 co-expressed with PGP9.5 or SP in cutaneous nerve fibers.Compared with the normal control skin,both the total length and average diameter of PGP 9.5-expressing nerve fibers were increased(11051.8±1900.9 μm vs 7264.0±2659.9 μm,4.23±0.15 μm vs 3.95±0.15 μm,both P<0.01)in pruritic lesions,while only the average diameter of SP-expressing nerve fibers was up-regulated(3.99±0.20 μm vs 3.80±0.07 μm,P<0.05),and the total length of them remained unchanged(4304.7±1455.0 μm vs 3380.0±1735.4 μm,P>0.05).Also,increased integral optimal density was observed for SP and PAR in pruritic lesions in comparison with the normal control skin (27.71±16.52 vs 12.63±4.31.35.99±8.63 vs 22.69±9.56.both P<0.05).Conclusion Our results indicate a hyper-plasia of cutaneous nerve fibers in chronic itchv skin lesions of AD and an increase in the expression of PAR2 and SP in the cutaneous nerve fibers,suggesting that the signal enhancement in PAR2 pathway may be related to the mechanism of pruritus in patients with AD.

ABSTRACT

Objective To improve the CR image quality and to promote the digital image standard constitution by analyzing the common problems and malpractiees in application of computed radiography. Methods Phenomenon and reasons of 107 CR junk-films from nine three-"A"-hospitals were analyzed, discussed,recorded,and statistised by 20 radiologists,radiographers and engineers.Results Among 107 junk fihns,there are 36 cases(33.64%)of incorrect operations,29 cases(27.10%)of artifacts in reading and transferring the data of IP,15 cases(14.02%)of artifacts in IP system,and 13 cases (12.15%)of selection of inappropriate radiographic parameters,and 9 eases(8.41%)of printer-failures, and 5 eases(4.67%)of inappropriate post-processing techniques.By analyzing the reasons of 107 junk films we found that 60.74% were due to less responsibilities and incorrect operations,and 35.51% were due to new problems in CR techniques,and other were due to inappropriate post-processing techniques. Conclusion Responsibilities,operation regulations,digital image quality standards,studying of new techniques and appropriate use of the post-processing techniques are the key points for improving the CR image quality and the diagnosis level.

ABSTRACT

Objective To explore the value of galactography in diagnosis of nipple discharge diseases. Methods Galactographies in 101 cases with nipple discharge confirmed by operation and pathology were analyzed restrospectively. Results There were breast duct ectasia in 23 cases, breast cystic hyperplasia in 12 cases , ductal inflammation in 8 cases, intraductal papilloma in 46 cases, ductal carcinoma in 9 cases, ductal tuberculosis in 1 case and normal duct in 2 cases. Conclusion The galactography is beneficial in diagnosis of the pathogenesis of galactorrhea and is of great value in differential diagnosis between benign and malignant lesions.
