Objective:To investigate the characteristics, influencing factors, consequences, coping strategies, and preventive measures of workplace violence in medical consortiums.Methods:Medical professionals from a specialized hospital in South China and its consortium members (2 primary-level, 1 secondary-level, and 1 tertiary-level hospitals) were surveyed in December 2022 and July 2023. Quantitative research included 1013 participants, while qualitative research involved 35 participants. Workplace violence was assessed using the "National Case Study Tool for Workplace Violence in Healthcare Institutions-Survey Questionnaire", with qualitative analysis conducted through semi-structured interviews. Inter-group comparisons employed chi-square tests or Fisher's exact probability test, with logistic regression models for bivariate analysis.Results:The overall incidence rates of violence, psychological violence, and physical violence in this medical consortium were 31.7% (321/1, 013) , 30.6% (310/1, 013) , and 3.3% (33/1, 013) , respectively. Specifically, the overall violence rates in Level 1, Level 2, and Level 3 hospitals were 22.7% (41/181) , 27.4% (43/157) , and 35.1% (237/675) . The physical violence rates were 1.1% (2/181) , 10.2% (16/157) , and 2.2% (15/675) , respectively. The psychological violence rates stood at 22.7% (41/181) , 24.8% (39/157) , and 34.1% (230/675) . The total violence in tertiary hospitals was significantly higher than that in tertiary hospitals ( F=10.10, P=0.002) , and the incidence of psychological violence in tertiary hospitals was significantly higher than that in tertiary hospitals ( Flevel 1 vs level 3=8.61, P=0.003; Flevel 2 vs level 3=4.96, P=0.026) , incidence of verbal insults ( Flevel 1 vs level 3=8.25, P=0.004; Flevel 2 vs level 3=6.36, P= 0.012) was significantly higher than that of level 1 and level 2 hospitals. The incidence of physical violence in secondary hospitals was significantly higher than that of other two-level hospitals ( P<0.001) . Compared with other types of violence, the incidence of verbal insults is highest in hospitals at all levels. Higher anxiety about violence was a risk factor for psychological violence in hospitals at all levels ( Flevel1 hospital=15.44, P=0.004; Flevel2 hospital=22.87, P<0.001; Flevel3 hospital=84.12, P<0.001) . Health workers in all three levels of hospitals has a high level of approval of existing workplace violence interventions. The main causes of workplace violence were poor communication between doctors and patients (13.2%) , service attitude problems (12.5%) and patient illness (16.9%) . Conclusion:Workplace violence remains prevalent within this medical consortium. Targeted measures should be implemented based on hospital size, functions, and patient demographics.

ObjectiveTo study the characteristics of imprinting template of flavonoid clusters in four Chinese medicines attributed to the lung meridian， and to establish an in vitro experimental approach for the study of the attribution of Chinese medicines to the lung meridian. MethodBased on 13 Chinese medicines， including Xanthii Fructus， Houttuyniae Herba， Fagopyri Dibotryis Rhizoma， Belamcandae Rhizoma and so on， which only belong to the lung meridian in Chinese Materia Medica（the 13^th Five-Year planning textbook of general higher education）， we identified four representative Chinese medicines， namely Houttuyniae Herba， Fagopyri Dibotryis Rhizoma， Belamcandae Rhizoma and Mori Cortex， and set up their fingerprints by high performance liquid chromatography（HPLC） and calculated the molecular connectivity indices of various components in the four Chinese medicines， the similarity to their mean value was calculated by included angle cosine method， so as to establish the quantitative relationship of construction versus imprinting ability， and to determine the order of each component in the lung meridian. A total of 7 reference substances， including chlorogenic acid， rutin， quercetin， isoquercitrin， hyperoside， epicatechin， and iridin， were selected to validate the overall conformational relationships of flavonoids of the model， as well as its predictive ability. ResultHouttuyniae Herba， Fagopyri Dibotryis Rhizoma， Belamcandae Rhizoma and Mori Cortex contained a total of 437 chemical components with an average molecular connectivity index similarity of 0.995 6. The four Chinese medicines contained a total of 204 flavonoids with an average molecular connectivity index similarity of 0.978 0， which was second only to the alkaloids with 0.985 1. The retention time（t_R） of the 7 reference substances showed a good conformational relationship with the similarity of the molecular connectivity index（t_R=831.4×S-790.3， r=0.861 4， P<0.01）， which was applicable to the in vitro attribution study of the position， similarity， and relative similarity with t_R of the cluster of 98.04% of flavonoids. Accordingly， the 1^st position was kuwanon D， with a similarity of molecular connectivity index of 0.987 7 and a t_R of 30.88 min， the 200^th position was chlorogenic acid， with a similarity of molecular connectivity index of 0.958 2 and a t_R of 6.36 min. The total first-order moment of the four Chinese medicines calculated by total statistical moment method of fingerprint was 24.26 min， ranked 21， which could characterize 99.19% of the whole， and the total first-order moment of the total peak area of the 7 reference substances in the four Chinese medicines was 20.00 min， with a rank of 46， which could characterize 98.68% of the whole. ConclusionFlavonoid clusters are suitable probes for the characterization of imprinting template for the study of the lung meridian， which can be established a quantitative imprinting method for meridian tropism of Chinese medicines in vitro.

Objective To establish a rapid detection method for zika virus based on direct amplification re-al-time fluorescent quantitative reverse transcription polymerase chain reaction(RT-PCR)technique.Methods A direct amplification RT-PCR technique for the rapid detection of zika virus in 5 samples(whole blood,serum,saliva,throat swab and urine)was established by using a special function DNA polymerase and a preferred PCR enhancer.Results The detection limits of the 5 samples were 103 PFU/mL in serum,102 PFU/mL in urine,throat swab,and saliva,and 104 PFU/mL in whole blood.The coefficient of goodness-fit of stand-ard curves was above 0.98,and the amplification efficiency was 90％-110％.Zika virus nucleic acid was suc-cessfully amplified,but non-zika virus nucleic acid was not amplified.Based on the repeatable detection of sam-ples from urine,whole blood,and saliva,the variation coefficient of 6 repeated Ct values at 106 PFU/mL and 102 PFU/mL concentrations were all＜5％.The zika virus detection method established by the direct amplifi-cation RT-PCR technique was consistent with the detection results of conventional RT-PCR technique.Only two serum samples were detected in eight zika virus samples,and the remaining 62 non-zika virus samples and 12 negative samples were not amplified.Conclusion A rapid detection method for zika virus based on direct ampli-fication RT-PCR technique is successfully established.The method is simple,rapid,sensitive and specific.

ObjectiveTo investigate the material basis of homologous and heterogeneous effect of Aurantii Fructus Immaturus（AFI） and Aurantii Fructus（AF） based on the total statistical moment analysis and molecular connectivity index（MCI）. MethodRelevant literature at home and abroad and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP） were consulted to establish the chemical composition database of AFI and AF， and set up their fingerprints by ultra-high performance liquid chromatography（UPLC）， and the total statistical moments and similarity parameters of the fingerprint were calculated. According to MCI， all components of AFI and AF were divided into different component groups， the average values of 0-8^th order（⁰χ-⁸χ） MCI of the common component groups of AFI and AF were calculated. ResultThe values of total zero-order moment（AUC_T） of AFI and AF were （10.57±2.45）×10⁶， （5.09±0.89）×10⁶ μV·s， the values of total first-order moment（MCRT_T） were （11.57±1.58）， （12.10±1.29） min， the values of total second-order moments（VCRT_T） were（24.49±2.30）， （26.49±2.54） min²， respectively. It showed that qualitative and quantitative parameters of AFI and AF were significantly different. The components with high similarity such as neohesperidin， hesperidin and narirutin were screened as the common potential pharmacodynamic components of AFI and AF. The non-common components of AFI， such as alysifolinone and imperatorin， and the non-common components of AF， such as neoeriocitrin and isosakuranin， with high similarity were screened out as potential heterogeneous components of AFI and AF. The composition groups of AFI and AF were classified into six categories， and the similarities between the composition groups of AFI and AF and the total constituents were 0.872-0.979 and 0.918-0.997， the average values of ⁰χ-⁸χ MCI of alkaloids in AFI and AF were 3.65 and 3.14， the average values of ⁰χ-⁸χ MCI of flavonoids were 8.47 and 8.47， the average values of ⁰χ-⁸χ MCI of volatile oils were 2.71 and 3.48， respectively. It showed that there were some differences in MCI of chemical constituents（groups） between AFI and AF. ConclusionThe chemical constituents（groups） of AFI and AF not only differ in content and species， but also in structural characteristics and structure-activity relationship， which can provide a basis for further explaining the scientific connotation of homologous and heterogeneous effect of AFI and AF.

ObjectiveBased on the network pharmacology system and quantitative spectroscopy of traditional Chinese medicine（TCM） compounds， a topological network analysis method with equilibrium constant as the core was established to further explore the interaction between allergenic components and their network targets in Shuanghuanglian injection（SHLI）， in order to provide new ideas and experimental basis for identifying and screening potential allergens of SHLI. MethodAfter one week of adaptive feeding， 72 SPF-grade SD male rats were randomly divided into blank group， SHLI standard group， Lonicerae Japonicae Flos（LJF） group， Scutellariae Radix（SR） group， Forsythiae Fructus（FF） group， and 7 groups of SHLI matching groups（groups 1-7）， with 6 rats in each group. Rats in each group were administered the drug intravenously and blood samples were taken after steady state， high performance liquid chromatography（HPLC） characterization profiles of the testing drugs and plasma components in each group were established， and the peak area changes of the drugs and plasma components in each group were calculated after the component groups were classified. Enzyme-linked immunosorbent assay（ELISA） was used to determine the changes of immunoglobulin E（IgE）， histamine（HIS）， tryptase（TPS）， total complement（CH50） and terminal complement complex（C5b-9） in animal blood samples. MATLAB R2020b v9.9.0 software was used to calculate the network balance constants of the component groups with the targets， and the eigenvalues of the matrices composed of network equilibrium constants were calculated and ranked according to their values. ResultELISA results showed that， compared with the blank group， groups 1-3 could significantly increase the IgE level， groups 1-2， groups 4-6 and SHLI standard group could significantly increase the HIS level， group 4 could significantly increase the CH50 level， groups 1， 3-4， LJF group and FF group could significantly increase the TPS level， SR group could significantly increase the C5b-9 level， and the differences were all statistically significant（P<0.05）. According to the retention time of chromatographic peaks， it was classified into 6 component groups from C1 to C6 by HPLC. The order of the network balance constants of each component group was C6>C4>C1>C5>C3>C2， indicating that C6 had the greatest effect on the allergic reaction， and was most likely to be the allergen. The sequence of eigenvalues was C2>C5b-9>C3>C1>CH50>C6>C5>IgE>TPS>C4>HIS， indicating that component group C2 had the greatest contribution to the whole network. ConclusionBased on the correlation analysis of SHLI component group and allergy-like target network， this study clarified that component group C6 may be a potential allergen in SHLI， and the component group C2 may be a key node in the mechanism of drug action， which can provide new strategies and methods for the screening of allergens in TCM injections.
