OBJECTIVE To investigate the effects of matrine （MT） on steatosis Chang Liver cell model induced by oleic acid （OA） and its possible mechanism. METHODS Chang Liver cells were divided into blank group， model group and MT low-dose， medium-dose group and high-dose groups （0.1， 0.5， 1.0 mmol/L）. Except for blank group， the other groups were treated with 1.0 mmol/L OA for 24 h to establish steatosis model， and MT groups were given corresponding concentrations of drugs for 24 h. The activities of steatosis Chang Liver cells were observed； the morphologies of intracellular lipid droplets were observed and lipid content was also determined. The contents of liver function indexes [alanine transaminase （ALT）， aspartate transaminase （AST）， total bilirubin （TBIL）， alkaline phosphatase （ALP）]， as well as mRNA and protein expressions of farnesoid X receptor （FXR）， cytochrome P450 7A1 （CYP7A1） and fibroblast growth factor 19 （FGF19） were all detected. RESULTS OA and MT had no significant effect on the activity of Chang Liver cells. After OA treatment， orange lipid droplets formed in cytoplasm； compared with blank group， relative lipid content and the levels of liver function indexes were increased significantly， while the mRNA and protein expressions of FXR， CYP7A1 and FGF19 were down-regulated significantly （P＜0.05）. After treatment of low， medium and high concentrations of MT， above indexes were all reversed significantly （P＜0.05）. CONCLUSIONS MT could significantly improve the lipid content and liver function indexes of steatosis Chang Liver cells induced by OA though regulating FXR/CYP7A1/ FGF19 signaling pathway.
摘要
Nonobstructive azoospermia (NOA) is a severe condition in infertile men, and increasing numbers of causative genes have been identified during the last few decades. Although certain causative genes can explain the presence of NOA in some patients, a proportion of NOA patients remain to be addressed. This study aimed to investigate potential high-risk genes associated with spermatogenesis in idiopathic NOA patients by whole-exome sequencing. Whole-exome sequencing was performed in 46 male patients diagnosed with NOA. First, screening was performed for 119 genes known to be related to male infertility. Next, further screening was performed to determine potential high-risk causative genes for NOA by comparisons with 68 healthy male controls. Finally, risk genes with high/specific expression in the testes were selected and their expression fluctuations during spermatogenesis were graphed. The frequency of cystic fibrosis transmembrane conductance regulator (CFTR) gene pathogenic variant carriers was higher in the NOA patients compared with the healthy controls. Potential risk genes that may be causes of NOA were identified, including seven genes that were highly/specifically expressed in the testes. Four risk genes previously reported to be involved in spermatogenesis (MutS homolog 5 [MSH5], cilia- and flagella-associated protein 54 [CFAP54], MAP7 domain containing 3 [MAP7D3], and coiled-coil domain containing 33 [CCDC33]) and three novel risk genes (coiled-coil domain containing 168 [CCDC168], chromosome 16 open reading frame 96 [C16orf96], and serine protease 48 [PRSS48]) were identified to be highly or specifically expressed in the testes and significantly different in the 46 NOA patients compared with 68 healthy controls. This study on clinical NOA patients provides further evidence for the four previously reported risk genes. The present findings pave the way for further functional investigations and provide candidate risk genes for genetic diagnosis of NOA.

Objective:To investigate the current situation of medical social worker supervision in Shanghai, for reference to promote the high-quality development of medical social work.Methods:From June to July 2022, a questionnaire survey was conducted on the in-service medical social workers in all medical institutions with medical social work departments or posts in Shanghai. The questionnaire mainly included demographic information, current status of supervision implementation, and effectiveness of supervision. The data were analyzed descriptively with t test for comparison between groups and the Pearson test was for correlation analysis. Results:A total of 99 medical social workers were included in this study, 65 had received supervision, and medical institutions where 58 people located had established the supervision system. The average scores of actual and expected supervisory support received by medical social workers were 3.71 and 4.20 respectively, and the mean burnout level score was 32.91. The effect of establishing a supervision institutions on burnout was statistically significant ( P<0.05) and actual access to supervision support was negatively associated with burnout ( P<0.05). Conclusions:The overall situation of medical social work supervision in Shanghai was positive, but the demand for supervision was not fully satisfied; Supervision had a positive impact on reducing the burnout level. It is suggested that medical social work should further strengthen the cultivation of supervisory talents, promote the construction of supervisory systems, and improve the quality of supervision.

摘要
The retention of emergency patients is a common problem faced by hospitals worldwide. In addition to medical problems, social, family, economic and other problems will also cause patients to stay in the emergency department. It not only brings challenges to patients’ own disease treatment and hospital operation and management, but also brings ethical dilemmas. Taking the service cases of medical social workers who involved in stranded patients in Shanghai E Hospital as an example, this paper analyzed 20 service records and interviews with social workers receiving cases, and combed the ethical dilemmas faced by medical social workers in the process of involving in emergency stranded patients. It was found that medical social workers faced many ethical dilemmas in the process of involving in emergency stranded patients, such as interpersonal relations and relevant legal regulations, the right to life and health and the right to informed consent, the self-determination of case owners and the allocation of medical resources. In this regard, it is suggested to solve the problem of patient retention by advocating the improvement of relevant systems and policies, building cooperative teams to smooth referral channels, strengthening education, and promoting family shared decision-making.

AIM: To study the effect and mechanism of Delicaflavone on migration and invasion of gefitinib-resistant lung cancer cell line PC-9/GR. METHODS: MTT assay was used to detect cell viability. Transwell and scratch assays were used to detect cell invasion and migration abilities. Western blotting was used to detect the expressions of MMP-9, MMP-2, E-cadherin, N-cadherin, Vimentin and PI3K/Akt/mTOR pathway-related proteins in PC-9/GR cells. RESULTS: Compared with control group, 20 mg/L Delicaflavone could significantly inhibit the viability of PC-9/GR cells for 24 h (P<0.05), while Delicaflavone below 10 mg/L had no significant effect on cell proliferation. The number of invasive cells and migrated cells were decreased significantly by Delicaflavone in a concentration-dependent way (P<0.05 and P<0.01). Delicaflavone could concentration-dependently reduce the expression of MMP-9, MMP-2, N-cadherin, vimentin (P<0.01), meanwhile up-regulate the expression of E-cadherin (P<0.01). In addition, Delicaflavone also decreased the expression of p-PI3K, p-Akt and p-mTOR in a concentration-dependent manner (P<0.01). CONCLUSION: Delicaflavone can inhibit the migration and invasion of PC-9/GR cells by regulating epithelial-mesenchymal transition via PI3K/Akt/mTOR pathway.
摘要
Natural deep eutectic solvent (NDES) is a kind of deep eutectic solvents (DESs) which is composed of natural substances with good biocompatibility. Those substances can function as hydrogen bond donor and acceptor, such as choline, amino acids, sugars, etc. NDES have been widely used in many fields due to their advantages of low cost, easy preparation and environmental friendliness. It is especially suitable for the pharmaceutical industry because of its good biocompatibility and safety for use. In this paper, we firstly review the molecular simulation methods for current design of DESs from the formation principle. And then, the materials and preparation of NDES are reviewed and the physicochemical properties are further described. Finally, we review the current application of NDES in pharmaceutics including increasing drug solubility, promoting drug permeability and enhancing oral drug absorption, and meanwhile their future applications in pharmaceutics were also prospected.

AIM: To investigate the mechanism of the involvement of SUMO-ylated Androgen receptor (AR) in tamoxifen resistance and the role of SUMO inhibitor ginkgolic acid in resistance. METHODS: Real-Time PCR was used to detect AR mRNA levels in parental cells MCF-7W and drug-resistant cells MCF-7R, AR protein levels and SUMO levels in MCF-7W and MCF-7R cells was performed by western blot, and CB/IP was applied to detect AR interacts with SUMOE3 ligase PIAS1 and HSP27 in MCF-7R cell chromatin, the transcriptional activity of SUMO AR was also evaluated by the fluorescent reporter gene experiment, the CCK-8 method and the trypan blue exclusion method were used to detect cell viability and cell viability respectively. RESULTS: The mRNA and protein expression levels of AR in MCF-7R cells were significantly higher than those in MCF-7W cells (P<0.05), and there was highly SUMOylated AR in MCF-7R cells. Further research found that there had an obvious interaction between AR and SUMO E3 ligase PIAS1 and HSP27, that was, the SUMOylated AR was modified by E3 ligase. Moreover, androgen R1881 could enhance the transcriptional activity of the SUMOylated AR in a concentration-dependent manner. Compared with ginkgo acid alone, 10 μmol/L of ginkgolic acid combined with 10 μmol/L of enzalutamide treated MCF-7R cells for 3 days, the cell number was significantly reduced, and the number of cell death increased significantly (P<0.05). CONCLUSION: The resistance mechanism of tamoxifen may be due to the enhanced AR transcription and activity increased by the hyperactive SUMOylated AR, SUMO inhibitor ginkgolic acid combined with AR antagonist enzalutamide can be a new strategy for the treatment of tamoxifen resistance.
摘要
As a drug carrier, polymer microspheres have been widely used in oral drug delivery systems, which can achieve the purposes of protecting drug stability, slowing drug release, enhancing immunity, and improving drug absorption. The polymer materials used in the preparation of microspheres can be derived from natural substances, such as cellulose, polysaccharides, and proteins. These materials can also be derived from synthetic polymer substances, such as polycaprolactone and polylactic acid. In this paper, the role of microspheres in oral drug delivery and the types of oral microspheres were reviewed to provide references for in-depth research and development of oral microspheres.
摘要
Objective:To identify and quantify spatiotemporal and kinematic gait parameters in a group of early-stage Parkinson′s disease (PD) patients compared with healthy subjects.Methods:Eight patients with PD (PD group, Hoehn-Yahr stage≤2.5) and seven age-matched healthy subjects (control group) were enrolled from the Department of Neurology, Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine between May 2017 and August 2018 for the study. The spatiotemporal and kinematic gait parameters were obtained by Vicon 3D optical motion analysis system under three conditions: single-task walking, dual-task walking and turning. The linear mixed model was used to compare the gait parameters between the two groups and analyze the interactive effects.Results:Arm swing amplitude in the PD group was lower than that in the control group ((0.63±0.15) m vs (0.89±0.27) m in single-task walking, (0.64±0.16) m vs (0.99±0.22) m in dual-task walking, β=-0.353, 95% CI -0.558--0.148, P=0.002). The PD group showed significantly higher arm swing asymmetry than the control group (12.48%±5.48% vs 6.96%±4.39% in single-task walking, 17.13%±4.05% vs 7.67%±5.23% in dual-task walking, β=8.992, 95% CI 4.148-13.836, P=0.001). A notable interactive effect of groups and task factors in arm swing asymmetry was found. The arm swing asymmetry of the PD group increased more than the control group in dual-task walking than in single-task walking (β=3.916, 95% CI 1.367-6.466, P=0.003). As for the gait characteristics of the lower limbs, stride length and step length of the PD group were lower than those of the control group ((1.10±0.17) m vs (1.31±0.10) m in stride length, β=-0.169, 95% CI -0.300--0.038, P=0.015; (0.55±0.09) m vs (0.65±0.04) m in step length, β=-0.081, 95% CI -0.150--0.013, P=0.023). For both groups, statistically significant differences were not observed in step width, stride length and step length between single-task and dual-task walking ( P>0.05). The PD group completed the turning process faster than the control group ((1.66±0.30) s vs (1.37±0.23) s, β=0.302, 95% CI 0.049-0.555, P=0.023). As for the rotation-onset pattern, no statistically significant differences were found between the PD and the control group for the onset of the head, trunk and pelvic rotation ( P>0.05). Participants started to rotate their heads before the pelvis in all groups (β=-0.060, 95% CI-0.107--0.014, P=0.011). Conclusions:The quantified gait parameters can more accurately reflect the gait characteristics of early PD. Patients with PD exhibited smaller arm swing magnitude, greater arm swing asymmetry, shorter stride length, and slower turning speed compared to the controls. Arm swing asymmetry further differs between subjects with early PD and controls under dual-task walking.
摘要
Objective: To screen out active ingredients, and predict the anti-cancer targets of Ligustri Lucidi Fructus-Astragali Radix based on the "herbs-active ingredient-action targets" network. Method: The traditional Chinese medicine (TCM) system pharmacology platform (TCMSP) was employed to screen out the active ingredients and putative targets of anti-cancer of glossy privet fruit and astragalus. DisGeNET database and Online Mendelian Inheritance in Man (OMIM database) were employed to predict the targets for treating cancer, and then "herbs-active ingredients-key targets" network was constructed by using Cytoscape software. The omicshare platform was employed to match the putative targets of ingredients and the targets for treating cancer. Finally, the protein interaction network of key targets was constructed by using String database, and the analysis of biological functions and pathways of them was carried out by using DAVID database. Result: Totally 33 drug active ingredients were screened out, involving a total of 203 targets, and 14 of them were related to cancer. These 14 key targets played an therapeutic role in treating cancer by regulating target proteins, such as ERBB2, AR, SRC, EGFR, ESR1, as well as proteoglycans in cancer, cancer pathways, microRNAs in cancer and other pathways. Conclusion: The therapeutic mechanism of Ligustri Lucidi Fructus-Astragali Radix reflects the multi-component, multi-target, and multi-pathway characteristics of TCMs, providing the scientific basis for further study and the material basis of Ligustri Lucidi Fructus-Astragali Radix against cancer.

Objective To interrogate the detection of anti-HLA antibodies using two methods of Luminex xMAP,and to compare their detection capacity and to analyze their misdetection rate for initial screening,providing more accurate results in clinical practice.Methods 214 serum samples from recipients with a history of sensitization before renal transplantation were collected and detected by LM (LABScreen Mixed) and LSA (LABScreen Single Antigen) respectively on the Luminex xMAP platform.Results For the LM detection,the positive rates of anti-HLA class Ⅰ and Ⅱ were 50.9％ and 23.4％ respectively,which were lower than those used by the LSA detection (58.9％ and 46.7％ respectively).The difference had statistical significance (P ＜ 0.05).The sensitivity,specificity,miss rate and mistake rate of anti-HLA class Ⅰ and Ⅱ[detection were 80.2％,90.9％,19.8％,9.1％ and 49.0％,99.1％,51.0％,0.9％ respectively.The missed detection gene with the highest rate was Cw * 17:01,B * 15:12,B * 45:01 for anti-HLA class Ⅰ and DPA1 * 01:03,DPB1 * 06:01,DPA1 * 01:03,DPB1 * 01:01 for anti-HLA class Ⅱ.The highest MFI value was 10603 and 3659.For the recipients with only blood transfusion history or pregnancy history,LM and LSA detection showed no statistically significant difference when detecting anti-HLA class Ⅰ antibodies,but had statistically significant difference when testing anti-HLA class Ⅱ antibodies.For the patients with history of both blood transfusion and pregnancy history,LM and LSA showed no significant difference in the detection of anti-HLA class Ⅰ antibodies and anti-HLA class Ⅱ antibodies.The miss rate of anti-HLA class Ⅰ antibody detection was lower than that of anti-HLA class Ⅱ antibody detection.Conclusion LSA detection has the higher sensivity and lower miss rate than LM detection.In the light of the disadvantage of LM detection as diagnostic preliminary screening,it is suggested that LSA detection should be used directly for the recipients with a history of sensitization.By this process optimization,it is more likely to cause missent inspection and the occurrence of rejection,as well as a poor long-term survival rate.
