In traditional Chinese medicine,jaundice is a liver and gallbladder disorder,primarily characterized by yellowing of the eyes,skin,and urine,with ocular yellowing being the most prominent feature.The understanding of jaundice pathogenesis in traditional Chinese medicine can be traced back to the Inner Canon of Huangdi.Despite the continuous development and improvement of successive generations of medical practitioners and a rich theoretical understanding of its pathogenesis being formed by the end of the Qing Dynasty,no unified view exists on whether the core pathological factor was dampness or blood stasis,nor on whether the primary disease location lay in the spleen and stomach or the liver and gallbladder.This article re-examines historical perspectives on jaundice pathogenesis within the context of traditional Chinese medicine theory,focusing on two key issues:pathological factors and the location of Zang and Fu.By integrating modern research approaches based on compound pathogenesis theory,and considering pathological factors,disease location according to Zang and Fu,and disease progression,a theoretical model is reconstructed,centered on the intermingling of dampness and blood stasis and integration of liver and spleen.Additionally,the insights and therapeutic strategies of multiple renowned clinical hepatology experts are incorporated to enrich the theoretical framework for jaundice treatment in traditional Chinese medicine and to enhance clinical efficacy.

Objective To investigate the association between bone mineral density(BMD)and metabolic associated fatty liver disease(MAFLD)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 300 patients with T2DM were enrolled and divided into T2DM with MAFLD group(n=162)and T2DM without MAFLD group(n=138)according to controlled attenuation parameters(CAP).The bone mineral density(BMD)of the patients was measured by dual energy X-ray absorptiometer.Results Compared with T2DM group,BMI,abdominal circumference(AC),FIns,FC-P,TG,HOMA-IR,ALB,liver stiffness measurement(LSM),CAP and BMD in T2DM+MAFLD group increased(P<0.05),while HDL-C and alkaline phosphatase(ALP)decreased(P<0.01).Spearman correlation analysis showed that the overall BMD of the male lumbar spine was positively correlated with smoking,AC,BMI,CAP,FIns,FC-P,HOMA-IR(P<0.05 or P<0.01),and negatively correlated with ALP(P<0.01).The overall hip BMD was positively correlated with smoking,AC,BMI,CAP,FC-P(P<0.05 or P<0.01).The overall BMD of the female lumbar spine is positively correlated with BMI and CAP(P<0.05 or P<0.01),but negatively correlated with age and ALP(P<0.05 or P<0.01).The overall hip BMD was positively correlated with BMI and CAP(P<0.05),and negatively correlated with age and ALP(P<0.05 or P<0.01).Multiple linear regression analysis shows that CAP is the influencing factor for overall lumbar BMD,while BMI is the influencing factor for overall hip BMD.Conclusions CAP is the influencing factor for overall lumbar BMD,while BMI is the influencing factor for overall hip BMD.

Objective:To explore the effects of the immune responses mediated by topological structures of three-dimensional bioprinted scaffolds on hair follicle cycle in mice.Methods:The study was an experimental research. The alginate-gelatin composite hydrogels were printed into scaffolds using a three-dimensional bioprinter and named T45 scaffolds, T60 scaffolds, and T90 scaffolds according to the 3 topological structures of the scaffolds (the rotation angles of the printhead during printing were 45°, 60°, and 90°, respectively), and the morphology of the three scaffolds was observed after cross-linking by naked eyes. Nine 8-week-old female C57BL/6J mice were divided into T45 group, T60 group, and T90 group, according to the random number table, with three mice in each group, and the T45, T60, and T90 scaffolds were subcutaneously implanted on the back of mice, respectively. On post implantation day (PID) 7, the hair growth in the dorsal depilated area of mice was observed, the thickness of the fiber capsule around the scaffolds was observed by hematoxylin-eosin staining, and the expression levels of CD68, bone morphogenetic protein-2 (BMP-2), and tumor necrosis factor (TNF) protein in the tissue surrounding the scaffolds were observed by immunofluorescence staining. The samples of the above experiments were all 3.Results:The topological structures of the three scaffolds were all clear with high fidelity after cross-linking. On PID 7, the hair growth was obvious in the dorsal depilated area of mice in T45 group and T90 group, while hair growth was slow in the scaffold implantation area of mice in T60 group, which was significantly different from that of the unimplanted area. On PID 7, compared with (18±4) μm in T90 group, the thickness of both the fiber capsule around the scaffolds ((39±4) and (55±8) μm) of mice in T45 group and T60 group was significantly increased ( P<0.05); the thickness of the fiber capsule around the scaffolds of mice in T60 group was also significantly increased compared with that in T45 group ( P<0.05). On PID 7, the expression level of CD68 protein in the tissue surrounding the scaffolds of mice in T60 group was significantly higher than the levels in T45 group and T90 group (with both P values <0.05). The expression level of BMP-2 protein in the tissue surrounding the scaffolds of mice in T60 group was significantly higher than the levels in T45 group and T90 group (with both P values <0.05), and the expression level of BMP-2 protein in the tissue surrounding the scaffolds of mice in T45 group was significantly higher than that in T90 group ( P<0.05). The expression level of TNF protein in the tissue surrounding the scaffolds of mice in T60 group was significantly lower than the levels in T45 group and T90 group (with both P values <0.05). Conclusions:Three-dimensional bioprinted scaffolds with different topological structures mediate different degrees of immune responses after being implanted in mice. A moderate immune response promotes hair growth in depilated area of mice, while an excessive immune response results inhibits the hair follicle entering into the anagen phase.

Objective:To analyze the molecular epidemiological characteristics of the Corona virus disease 2019 (COVID-19) cases in Shijiazhuang, which can reveal the origin of the outbreak and provide a scientific basis for COVID-19 prevention and control.Methods:From January 2 to January 8, 2021, a total of 404 samples from 170 COVID-19 cases were collected from the Shijiazhuang Fifth Hospital. The consensus sequence of 2019 novel Coronavirus(2019-nCoV) was obtained through multiplex polymerase chain reaction-based sequencing. The sequences of 170 COVID-19 cases were analyzed by the PANGOLIN, and the data were statistically analyzed by T-test.Results:Among the 404 COVID-19 samples, a total of 356 samples obtained high quality genome sequences (>95%,100×sequencing depth). The whole genome sequences of 170 COVID-19 cases were obtained by eliminating repeated samples. All 170 sequences were recognized as lineage B1.1 using PANGOLIN. The number of single nucleotide polymorphism arrange from 18-22 and most of the single nucleotide polymorphism were synonymous variants. All of 170 genomes could be classified into 48 sub-groups and most of the genomes were classified into 2 sub-groups (66 and 31, respectively).Conclusions:All cases in this study are likely originated from one imported case. The viruses have spread in the community for a long time and have mutated during the community transmission.

Objective:To investigate the diagnostic values of interleukin-22 (IL-22), interferon-γ(IFN-γ)and macrophage migration inhibition factor (MIF) in pleural effusion for tuberculosis pleurisy.Methods:From April 2018 to May 2019, a total of 77 patients including 45 cases of tuberculous pleurisy, 19 cases of malignant pleurisy, 13 cases of parapneumonia and 13 cases of healthy control in Wuxi Fifth People′s Hospital were enrolled. The levels of IL-22, IFN-γ and MIF in plasma and pleural effusion were detected by enzyme linked immunosorbent assay (ELISA). Mann-Whitney U test was used for statistical analysis.The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic values of IL-22, IFN-γ and MIF for tuberculous pleurisy. Results:The median levels of IL-22, IFN-γ, MIF and adenosine deaminase in 45 cases with pleural effusion in tuberculosis pleurisy group were 396.8 ng/L, 2 200.0 ng/L, 241.3 μg/L and 70.8 U/L, respectively, which were all significantly higher than 32 cases with non-tuberculosis pleurisy group, including 19 cases with malignant pleurisy and 13 cases with parapneumonia (52.8 ng/L, 232.3 ng/L, 179.6 μg/L and 17.0 U/L, respectively). The differences were all statistically significant ( U=179.000, 118.500, 287.000, 162.000, respectively, all P<0.05). The median levels of IL-22 and IFN-γ in plasma of tuberculosis pleurisy group were 20.0 ng/L and 45.9 ng/L, respectively, which were both higher than healthy control group (14.3 ng/L and 33.4 ng/L, respectively). The level of MIF was 96.2 μg/L, which was lower than healthy control (159.5 μg/L). The differences were all statistically significant ( U=74.000, 13.000 and 73.000, respectively, all P<0.05). The areas under ROC curve (AUC) of IL-22, IFN-γ and MIF in pleural effusion for the diagnosis of tuberculosis pleurisy were 0.876, 0.917 and 0.682, respectively.The sensitivities were 93.75%, 100.00% and 63.64%, respectively; the specificities were 82.22%, 91.11% and 65.85%, respectively. The median levels of IL-22 and IFN-γ in plasma in tuberculosis pleurisy group at two months of follow-up after anti-tuberculosis therapy were 16.0 ng/L and 33.9 ng/L, respectively, which were both lower than baseline (20.0 ng/L and 44.7 ng/L, respectively). The differences were both statistically significant ( U=2.156 and 2.221, respectively, both P<0.05). Conclusion:IFN-γ and IL-22 in pleural effusion could be used as effective indicators to identify tuberculous pleurisy, and the dynamic monitoring of IL-22 in patients′plasma could be an important biomarker in evaluating the efficacy of anti-tuberculosis treatment.

Objective? To define the difficulty coefficient of Operating Room nursing items which is suitable for difficulty evaluation and can represent the workload of Operating Room nursing. Methods? From January 2017 to March 2018, through literature review, questionnaire survey and expert demonstration meeting, the nursing work items and operational difficulty indicators suitable for difficulty evaluation in Operating Room were determined.

It can quantify the difficulty of Operating Room nursing work items and enhance the rationality of Operating Room nursing workload counting.

Objective To evaluate the safety and efficacy of endoscopic ultrasound (EUS) guided ethanol ablation of benign insulinoma and compare its' advantages and disadvantages with surgical treatment. Methods From April 2011 to February 2016, clinical data of 38 patients with benign insulinoma treated by EUS-guided ethanol ablation or surgical treatment were retrospectively analyzed. Results 97.4% (37/38) patients had a typical clinical manifestation of Whipple's triad, and the I/G ratio of 82.9% patients (29/35) was more than 0.3 with their onset of hypoglycemia. The positive preoperative etiologic diagnosis rates of transabdominal ultrasonography, CT, MRI, PET/CT and EUS were 50.0%, 67.6%, 66.7%, 75.0%, 89.7% respectively. In the current study, 18 patients underwent EUS-guided ethanol ablation (EUS-FNI group) and 20 patients received surgicaltreatment (surgical group). Compared with the surgical group, the operation time, intraoperative hemorrhage volume, postoperative complications, length of stay and hospitalization costs were significantly reduced in the EUS-FNI group (P < 0.05). No treatment-related complications was observed in EUS-FNI group, while 40.0% (8/20) patients in surgical group had complications. During the follow-up period, all these patients maintained stable blood glucose without taking medication, and there's no recurrence of insulinoma in EUS-FNI group after the last treatment with alcohol injection; In surgical group, only 90.0% (18/20) patients had no recurrence, episode of hypoglycemia was less after the operation in 10.0% (2/20) patients. Conclusion EUS-guided ethanol ablation of benign insulinoma is safe and effective, compared with traditional surgical treatment, EUS-guided ethanol ablation is minimally invasive, costs less, recovers fast after treatment and has fewer complications.
