By applying "homeostasis" to the study of the meridian and collateral system, the concept of meridian and collateral homeostasis has been proposed which refers to a balanced and stable state of meridian and collateral system, and plays an important role in maintaining body health and can provide a reference for the diagnosis and treatment of diseases. Phenomics realizes the cross-scale correlation from micro-phenotypic data, such as genome, proteome, and metabolome, to macro-phenotypic data, such as physiological state, behavioral activities, and external manifestations. From the perspective of phenomics, this paper proposes a meridian and collateral homeostasis dynamic mapping model of "macroscopic signs and microscopic expression". This model combines macro signs such as the four examinations of traditional Chinese medicine (TCM), biophysical indicators of acupoints, and micro expression information such as genes, proteins, and metabolism, and systematically investigates the relationship between meridian and collateral homeostasis and health and disease, thereby providing ideas and references for the identification of pre-disease states as well as precise diagnosis and treatment in TCM.

Objective:To analyze the detection strategy and basic detection situation of markers of infectious diseases transmitted by transfusion in blood testing laboratories of blood stations in China.Methods:Based on the data of practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021, the data on the testing strategies and the basic detection information of the markers for the transmission of infectious diseases through transfusion in the member laboratories of the practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021 were collected, and the situation of the selection for testing markers, testing strategy and the testing method and other relevant aspects were sorted out and analyzed by charts.Results:The selection of the testing markers was consistent, but HTLV testing item was added in some member laboratories. The detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously was adopted in 47 member blood stations; 3) NAT method was dominated by mini pool-NAT in member laboratories. The number of members adopting mini-pools of 8 (MP8)-NAT decreased from 17 in 2017 to 14 in 2021, while the number of members adopting mini-pools of 6 (MP6)-NAT increased from 13 in 2017 to 22 in 2021; Roche NAT system accounted for the largest proportion.Conclusions:In order to ensure blood safety and avoid missing detection, the blood stations still adopt the detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously; Meanwhile, in order to increase the NAT positive rate, the proportion of mini pool-NAT mainly decreased year by year despite its dominating role, while the proportion of individual donation-NAT increased year by year; NAT method is transiting from mini-pools of 8 (MP8) to mini-pools of 6 (MP6); The proportion of imported NAT system used in NAT laboratory is relatively large.

Objective:To examine the effect of thrombolytic therapy of Budd-Chiari syndrome (B-CS) with inferior vena cava (IVC) thrombosis, and the prognosis factors of it.Methods:The clinical data of 67 patients of B-CS with IVC thrombosis treated in the Department of Hepatopancreatobiliary Surgery, the First Affiliated Hospital of Zhengzhou University from January 2013 to August 2020 were analyzed retrospectively. There were 30 males and 37 females. The age was (47.7±11.1) years(range: 18 to 72 years). All patients received catheter directed thrombolysis, and the thrombolysis process, complications and outcomes were analyzed. All patients received IVC balloon angioplasty after thrombolytic therapy. The t test, χ 2 test, Mann-Whitney U test were used for univariate analysis of the prognosis factors of thrombolysis effects, while unconditional Logistic regression model were used for multivariate analysis. Results:In the 67 patients, 47 cases succerssed in thrombolytic therapy. The successful rates of thrombolysis at 1-, 2-, 3- and 4-week were 9.0%, 29.9%, 64.2% and 70.1%, respectively. The rates of thrombolytic catheter-related infection at 1-, 2-, 3- and 4-week were 1.5%, 4.5%, 14.9% and 31.3%, respectively. No serious complications such as symptomatic and acute pulmonary embolism occurred during perioperative period of IVC balloon angioplasty. Univariate analysis showed that differences in thrombus length ((36.7±18.1) mm vs. (52.0±16.4) mm, t=-3.234, P=0.002), Child-Pugh classification (class A/B/C: 37/8/2 vs. 10/8/2, Z=-2.310, P=0.021) and pre-opening IVC proportion (68.1% (32/47) vs. 35.0% (7/20), χ2=6.313, P=0.012) were statistically significant. The thrombus length ( OR=0.948, 95% CI: 0.913 to 0.984, P=0.005), pre-opening IVC ( OR=5.451, 95% CI: 1.469 to 20.228, P=0.011) were independent prognosis factors of thrombolytic effect. Conclusions:Thrombolytic therapy for B-CS with IVC thrombosis were satisfactory, and the thrombolysis duration should be confined within 3 weeks. IVC balloon angioplasty is safe and effective for patients failing in thrombolysis, and pre-opening IVC is an important method to improve the thrombolytic effect.

Objective:To evaluate lower facial profile in females in different skeletal patterns.Methods:Investigation pictures of three females with beautiful lower facial profiles from Department of Orthodontics, Henan Stomatological Hospital were collected. The skeletal patterns of these females were classified as average, low and high angle, respectively.Upper lip process point (UL) was moved backwards horizontally to reach towards the E line and go even further gradually in above pictures. The distance changed according to E line was defined as DE value. If UL was in front of E line,DE value was denoted as positive, or else negative. Collectively, we obtained 30 pictures (10 pictures in each skeletal facial type) with different DE values (-5, -4, -3, -2, -1, 0, 1, 2, 3, 4 mm), which were divided into average, low and high angle group according to the skeletal facial type. The pictures were evaluated by 144 randomly-selected adult orthodontic patients [66 males, 78 females, aged (29.4±7.7) years] who visited Department of Orthodontics, Henan Stomatological Hospital from June to September, 2019 and 138 orthodontists (including qualified orthodontists and postgraduate orthodontic students [60 males, 78 females, aged (32.2±7.1) years] who participated orthodontics conferences in Henan Stomatological Hospital in June, 2019. The acceptance rate was calculated and rate above 60% was deemed as acceptable DE range. Evaluators were also asked to choose the most esthetic profiles for the best DE value in each skeletal facial type.Data discrepancy was analyzed using Kruskal-Wallis analysis and chi-square test. Results:Most accepted DE was -2 mm among total investigators including orthodonticpatients and orthodontists. There was no difference in total acceptance rate between orthodontists and patients ( P>0.05). There was statistic difference in total acceptance rate in different skeletal patterns between orthodontic patients and orthodontists ( P<0.05). In total investigators, total acceptance rate was 62.1% (1 752/2 820) in average angle group, 55.4%(1 563/2 820) in high angle group and 33.5%(946/2 820) in low angle group, respectively. Acceptable DE range in three facial types was -4~2 mm (average angle), -2~2 mm (high angle) and -2~-1 mm (low angle), respectively. Conclusions:According to the evaluation of both orthodontic patients and orthodontists, the best DE was-2 mm.Total acceptance rate and acceptable DE range ranked first in average angle group, second in high angle group and third in low angle group.

Objective To compare the production of farnesol between Candida albicans (C.albicans) biofilms formed by resistant and standard strains in different media,and to investigate the changing trend of farnesol production in different phases of biofilm formation and the features of farnesol production by resistant C.albicans.Methods Fluconazole-resistant C.albicans strains were induced in vitro.Standard strains and fluconazole-resistant strains of C.albicans were separately inoculated onto different media,including RPMI 1640 medium,yeast extract peptone dextrose (YPD) medium,yeast nitrogen base (YNB) + 0.5% glucose medium,RPMI 1640 + 10% fetal calf serum (FCS),so as to form C.albicans biofilms.Morphological changes of C.albicans biofilms at 24 hours were observed under an inverted microscope,and gas chromatography-mass spectrometry (GC/MS)was performed to detect the level of farnesol at 1.5,3,6,12,24,36 and 48 hours.Results There were no obvious differences in the morphology of C.albicans biofilms between the resistant and standard strains when they were cultured in the same medium,while the morphology of C.albicans biofilms markedly differed between the 2 kinds of strains in the different media.Three-factor analysis of variance showed that the production of farnesol in the C.albicans biofilms changed over time (F =70.628,P < 0.001).Concretely speaking,during the formation of resistant and standard C.albicans biofilms,the production of farnesol gradually increased in the RPMI 1640,YPD and YNB + 0.5% glucose media until the biofilms matured,then showed a decreasing trend.However,the time to peak levels of farnesol was different between the 2 kinds of strains in these media.Moreover,the levels of farnesol in the 2 kinds of strains both slowly increased in the RPMI 1640 + 10% FCS medium within 12-48 hours.Culture media also significantly affected the production of farnesol (F =176.665,P < 0.001),and the levels of farnesol in the resistant and standard C.albicans biofilms were both higher in the YNB + 0.5% glucose medium.When resistant and standard strains were separately cultured in the RPMI 1640 media and the YPD media,the level of farnesol was significantly higher in the resistant strains than in the standard stains (RPMI 1640 media at 36 hours:1.157 ± 0.064 vs.0.250 ± 0.075,P < 0.05;YPD media at 6 hours:0.262 ± 0.036 vs.0.055 ± 0.062,P < 0.05;YPD media at 12 hours:0.730 ± 0.030 vs.0.482 ± 0.024,P < 0.05).However,when they were separately cultured in the YNB + 0.5% glucose media,the farnesol level was significantly higher in the standard stains than in the resistant strains (36 hours:2.950 ± 0.677 vs.0.523 ± 0.266,P =0.020).Conclusion The media markedly affect the production of farnesol in the C.albicans biofilms,and there is a certain difference in the production of farnesol between resistant and standard C.albicans strains.

Baicalein(BE), a natural flavonoid mainly extracted from Radix Scutellaria, has comprehensive pharmacological actions such as anti-inflammation, anti-virus and anti-cancer activities. It belongs to BCS class II compound with relatively low oral bioavailability. The current study aims to improve its aqueous solubility and dissolution and hence to enhance its oral absorption by cocrystallization technique. Slurry crystallization method was employed to prepare baicalein cocrystal with co-former caffeine(CA), followed by physicochemical characterizations with DSC, XRPD and FTIR. Compared to BE and physical mixture of BE and CA, BE-CA cocrystal had a significantly higher dissolution of BE. In addition, in comparison to BE, this cocrystal achieved reduced time to peak(tmax)as well as significantly higher peak plasma concentrations(cmax)and area under the curve(AUCs)for both BE and its active metabolite baicalin(BI)in rats, suggesting enhanced the oral bioavailability of BE.
