ABSTRACT

Objective: To investigate the clinical efficacy of entecavir combined with Biejiajian pills and its influence on TCM syndrome scores during the treatment of chronic hepatitis B with hepatic fibrosis and blood stasis syndrome by prospective, randomized and controlled study. Methods: Patients with chronic hepatitis B with hepatic fibrosis and blood stasis syndrome were selected as the research subjects and randomly divided into a treatment group and a control group. Entecavir plus Biejiajian pills or entecavir plus a simulant of Biejiajian pills were given for 48 weeks. The changes in liver stiffness measurement (LSM) and TCM syndrome scores before and after treatment were compared between the two groups to analyze the correlation. The data between groups were analyzed by t-test/Wilcoxon rank sum test or χ(2) test. Pearson correlation coefficient was used to analyze the correlation between TCM syndrome scores and LSM values. Results: After 48 weeks of treatment, the LSM values of the two groups were significantly lower than those of the baseline (P < 0.001), liver fibrosis was significantly improved, and the LSM values of the treatment group were lower than those of the control group [(8.67 ± 4.60) kPa and (10.13 ± 4.43) kPa, t = -2.011, P = 0.049]. After 48 weeks of treatment, the TCM syndrome scores of the two groups were significantly reduced compared with the baseline (P < 0.001), and the clinical symptoms were significantly relieved, and the total effective rates of the improvement of the TCM syndrome scores in the two groups were 74.19% and 72.97%, respectively, but the differences between the groups were not statistically significant (χ(2) = 0.013, P = 0.910). Correlation analysis showed that there was no obvious trend between TCM syndrome scores and LSM values. There were no serious adverse reactions associated with the drug during the observation period of this study. Conclusion: Based on antiviral treatment with entecavir, regardless of whether it is combined with the Biejiajian pill, it can effectively reduce the LSM value, improve liver fibrosis, reduce TCM syndrome scores, and alleviate symptoms in patients with chronic hepatitis B with liver fibrosis and blood stasis syndrome. Compared with entecavir alone, the combined Biejia pill has greater efficacy in improving liver fibrosis and a favorable safety profile, meriting its implementation and widespread application.

ABSTRACT

Objective: To investigate the role of Maresin1 (MaR1) in hepatic ischemia-reperfusion injury (HIRI). Methods: The HIRI model was established and randomly divided into a sham operation group (Sham group), an ischemia-reperfusion group (IR group), and a MaR1 ischemia-reperfusion group (MaR1+IR group). MaR1 80ng was intravenously injected into each mouse's tail veins 0.5h before anesthesia. The left and middle hepatic lobe arteries and portal veins were opened and clamped. The blood supply was restored after 1h of ischemia. After 6h of reperfusion, the mice were sacrificed to collect blood and liver tissue samples. The Sham's group abdominal wall was only opened and closed. RAW267.4 macrophages were administered with MaR1 50ng/ml 0.5h before hypoxia, followed by hypoxia for 8h and reoxygenation for 2h, and were divided into the control group, the hypoxia-reoxygenation group (HR group), the MaR1 hypoxia-reoxygenation group (MaR1 + HR group), the Z-DEVD-FMK hypoxia-reoxygenation group (HR+Z group), the MaR1 + Z-DEVD-FMK hypoxia-reoxygenation group (MaR1 + HR + Z group), and the Con group without any treatment. Cells and the supernatant above them were collected. One-way analysis of variance was used for inter-group comparisons, and the LSD-t test was used for pairwise comparisons. Results: Compared with the Sham group, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), interleukin (IL)-1β, and IL-18 in the IR group were significantly higher (P < 0.05), with remarkable pathological changes, while the level in the MaR1 + IR group was lower than before (P < 0.05), and the pathological changes were alleviated. Compared with the Con group, the HR group had higher levels of IL-1β and IL-18 (P < 0.05), while the MaR1 + HR group had lower levels of IL-1β and IL-18 (P < 0.05). Western blot showed that the expressions of caspase-3, GSDME, and GSDME-N were significantly higher in the HR group and IR group than in the other groups; however, the expression was lower following MaR1 pretreatment. The Z-DEVD-FMK exploration mechanism was inhibited by the expression of caspase-3 in HIRI when using MaR1. Compared with the HR group, the IL-1β and IL-18 levels and the expressions of caspase-3, GSDME, and GSDME-N in the HR + Z group were decreased (P < 0.05), while the expression of nuclear factor κB was increased, but following MaR1 pretreatment, nuclear factor κB was decreased. There was no significant difference in the results between the MaR1 + H/R group and the MaR1 + H/R + Z group (P > 0.05). Conclusion: MaR1 alleviates HIRI by inhibiting NF-κB activation and caspase-3/GSDME-mediated inflammatory responses.

ABSTRACT

Objective: To quantitatively estimate the incidence of COVID-19 in different backgrounds, including vaccination coverage, non-pharmacological interventions (NPIs) measures, home quarantine willingness and international arrivals, and the demands of healthcare resource in Shanghai in the context of optimized epidemic prevention and control strategies. Methods: Based on the natural history of 2019-nCoV, local vaccination coverage and NPI performance, an age-structured Susceptible-Exposed-Infections-Removed (SEIR) epidemic dynamic model was established for the estimation of the incidence of COVID-19 and demand of hospital beds in Shanghai by using the data on December 1, 2022 as the basis. Results: Based on current vaccination coverage, it is estimated that 180 184 COVID-19 cases would need treatment in hospitals in Shanghai within 100 days. When the booster vaccination coverage reaches an ideal level, the number of the cases needing hospitalization would decrease by 73.20%. School closure or school closure plus workplace closure could reduce the peak demand of regular beds by 24.04% or 37.73%, respectively, compared with the situation without NPI. Increased willingness of home quarantine could reduce the number of daily new cases and delay incidence peak of COVID-19. The number of international arrivals has little impact on the development of the epidemic. Conclusions: According to the epidemiological characteristics of COVID-19 and the actual situation of vaccination in Shanghai, the incidence of COVID-19 and health resource demand might be reduced by increasing vaccination coverage and early implementation of NPI.

ABSTRACT

OBJECTIVES@#To investigate the role and mechanism of circRNA-SR-related CTD associated factor 8 (SCAF8) in regulating endothelial cell pyroptosis in high glucose environment.@*METHODS@#Human umbilical vein endothelial cells (HUVECs) were cultured and divided into six groups. The normal control group and high glucose control group were cultured in cell culture medium with 5 and 33 mmol/L glucose, respectively. The RNA control group, circRNA-SCAF8 inhibition group, miR-93-5p overexpression group and miR-93-5p inhibition group were added with non-functional siRNA, circRNA-SCAF8 inhibitor, miR-93-5p overexpression molecule and miR-93-5p inhibitor in high glucose environment, respectively. Cell viability and pyroptosis were detected by cell counting kit-8 (CCK-8) assay, flow cytometry and Hoechst 33342/propidium iodide fluorescence double staining. Western blotting and enzyme-linked immunosorbent assay were used to detect the expression of pyroptosis-related factors including apoptosis-associated speck-like protein containing a CARD (ASC), cysteine aspartic acid specific protease-1 (caspase-1) and Gasdermin D (GSDMD), NOD like receptor protein 3 (NLRP-3), thioredoxin interacting proteins (TXNIP), IL-18 and IL-1β. The expression of circRNA-SCAF8, miR-93-5p and TXNIP was detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Fluorescence in situ hybridization (FISH) was used to locate circRNA-SCAF8 and miR-93-5p. Dual luciferase assay was used to verify the targeted regulatory relationship between miR-93-5p and upstream and downstream molecules.@*RESULTS@#Compared with the RNA control group, the cell survival rate of circRNA-SCAF8 inhibition group and miR-93-5p overexpression group increased (both P<0.01), the pyroptosis decreased (both P<0.01), and the expressions of pyroptosis-related factors such as TXNIP, NLRP-3, caspase-1, GSDMD, ASC, IL-18 and IL-1β were significantly decreased (all P<0.05). The expression of miR-93-5p was significantly increased after inhibition of circRNA-SCAF8 (P<0.01), and the expression of circRNA-SCAF8 tended to decrease after overexpression of miR-93-5p, but with no statistical significance (P>0.05). Dual luciferase assay showed that miR-93-5p downre-gulated circRNA-SCAF8 expression by binding to the 3 ´ UTR region of circRNA-SCAF8, and miR-93-5p downregulated TXNIP expression by binding to the 3 ´ UTR region of TXNIP. FISH showed that circRNA-SCAF8 and miR-93-5p were both located in the cytoplasm and were highly associated in the cells. qRT-PCR showed that the relative expression of TXNIP increased or decreased after overexpression or inhibition of miR-93-5p compared with the RNA control group, respectively (both P<0.05), suggesting that miR-93-5p could regulate TXNIP gene expression.@*CONCLUSIONS@#CircRNA-SCAF8/miR-93-5p/TXNIP axis is involved in the regulation of pyroptosis in HUVECs under high glucose.

ABSTRACT

Primary ciliary dyskinesia (PCD) is a rare hereditary orphan condition that results in variable phenotypes, including infertility. About 50 gene variants are reported in the scientific literature to cause PCD, and among them, dynein axonemal assembly factor 4 ( DNAAF4 ) has been recently reported. DNAAF4 has been implicated in the preassembly of a multiunit dynein protein essential for the normal function of locomotory cilia as well as flagella. In the current study, a single patient belonging to a Chinese family was recruited, having been diagnosed with PCD and asthenoteratozoospermia. The affected individual was a 32-year-old male from a nonconsanguineous family. He also had abnormal spine structure and spinal cord bends at angles diagnosed with scoliosis. Medical reports, laboratory results, and imaging data were investigated. Whole-exome sequencing, Sanger sequencing, immunofluorescence analysis, hematoxylin-eosin staining, and in silico functional analysis, including protein modeling and docking studies, were used. The results identified DNAAF4 disease-related variants and confirmed their pathogenicity. Genetic analysis through whole-exome sequencing identified two pathogenic biallelic variants in the affected individual. The identified variants were a hemizygous splice site c.784-1G>A and heterozygous 20.1 Kb deletion at the DNAAF4 locus, resulting in a truncated and functionless DNAAF4 protein. Immunofluorescence analysis indicated that the inner dynein arm was not present in the sperm flagellum, and sperm morphological analysis revealed small sperm with twisted and curved flagella or lacking flagella. The current study found novel biallelic variants causing PCD and asthenoteratozoospermia, extending the range of DNAAF4 pathogenic variants in PCD and associated with the etiology of asthenoteratozoospermia. These findings will improve our understanding of the etiology of PCD.

ABSTRACT

OBJECTIVE To explore the way to re-use epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) in patients with EGFR-TKI-induced interstitial pneumonia (IP), using osimertinib as an example. METHODS The IP treatment regimen and re-use of EGFR-TKI regimen in a patient who developed IP after the use of osimertinib were analyzed. And a literature review was made by combining the characteristics of the cases which reported in the literature and the characteristics of this case. RESULTS The patient’s IP symptoms due to treatment with osimertinib had resolved after treatment. The patient’s IP symptoms also did not worsen after using almonertinib in combination with hormones as re-use of EGFR-TKI regimen. However, almonertinib was discontinued as the patient experienced disease progression. The adverse reactions of IP needed to be dealt with in time, the EGFR-TKI should be discontinued and symptomatic treatment should be given. CONCLUSIONS EGFR-TKI targeted therapy could be re-selected by replacing EGFR-TKI, adjusting the dose of EGFR-TKI, and using hormones in combination. EGFR-TKI-induced adverse drug reactions of IP are rare, but need to be observed closely. If other EGFR-TKI is used, close monitoring of adverse reactions and curative effects are also required in order to adjust the patient’s treatment plan in time.

ABSTRACT

OBJECTIVE@#To investigate the value of lymphatic contrast-enhanced ultrasound (LCEUS) with intra-glandular injection of contrast agent for diagnosis of central compartment lymph node metastasis of thyroid cancer.@*METHODS@#From November, 2020 to May, 2022, the patients suspected of having thyroid cancer and scheduled for biopsy at our center received both conventional ultrasound and LCEUS examinations of the central compartment lymph nodes before surgery. All the patients underwent surgical dissection of the lymph nodes. The perfusion features in LCEUS were classified as homogeneous enhancement, heterogeneous enhancement, regular/irregular ring, and non-enhancement. With pathological results as the gold standard, we compared the diagnostic ability of conventional ultrasound and LCEUS for identifying metastasis in the central compartment lymph nodes.@*RESULTS@#Forty-nine patients with 60 lymph nodes were included in the final analysis. Pathological examination reported metastasis in 34 of the lymph nodes, and 26 were benign lymph nodes. With ultrasound findings of heterogeneous enhancement, irregular ring and non-enhancement as the criteria for malignant lesions, LCEUS had a diagnostic sensitivity, specificity and accuracy of 97.06%, 92.31% and 95% for diagnosing metastatic lymph nodes, respectively, demonstrating its better performance than conventional ultrasound (P < 0.001). Receiver-operating characteristic curve analysis showed that LCEUS had a significantly greater area under the curve than conventional ultrasound for diagnosing metastatic lymph nodes (94.7% [0.856-0.988] vs 78.2% [0.656-0.878], P=0.003).@*CONCLUSION@#LCEUS can enhance the display and improve the diagnostic accuracy of the central compartment lymph nodes to provide important clinical evidence for making clinical decisions on treatment of thyroid cancer.

ABSTRACT

OBJECTIVES@#To explore the cytotoxicity of four wild mushrooms involved in a case of Yunnan sudden unexplained death (YNSUD), to provide the experimental basis for prevention and treatment of YNSUD.@*METHODS@#Four kinds of wild mushrooms that were eaten by family members in this YNSUD incident were collected and identified by expert identification and gene sequencing. Raw extracts from four wild mushrooms were extracted by ultrasonic extraction to intervene HEK293 cells, and the mushrooms with obvious cytotoxicity were screened by Cell Counting Kit-8 (CCK-8). The selected wild mushrooms were prepared into three kinds of extracts, which were raw, boiled, and boiled followed by enzymolysis. HEK293 cells were intervened with these three extracts at different concentrations. The cytotoxicity was detected by CCK-8 combined with lactate dehydrogenase (LDH) Assay Kit, and the morphological changes of HEK293 cells were observed under an inverted phase contrast microscope.@*RESULTS@#Species identification indicated that the four wild mushrooms were Butyriboletus roseoflavus, Boletus edulis, Russula virescens and Amanita manginiana. Cytotoxicity was found only in Amanita manginiana. The raw extracts showed cytotoxicity at the mass concentration of 0.1 mg/mL, while the boiled extracts and the boiled followed by enzymolysis extracts showed obvious cytotoxicity at the mass concentration of 0.4 mg/mL and 0.7 mg/mL, respectively. In addition to the obvious decrease in the number of HEK293 cells, the number of synapses increased and the refraction of HEK293 cells was poor after the intervention of Amanita manginiana extracts.@*CONCLUSIONS@#The extracts of Amanita manginiana involved in this YNSUD case has obvious cytotoxicity, and some of its toxicity can be reduced by boiled and enzymolysis, but cannot be completely detoxicated. Therefore, the consumption of Amanita manginiana is potentially dangerous, and it may be one of the causes of the YNSUD.

ABSTRACT

We report a case of a long-term survivor of heart transplant who developed severe COVID-19 and was treated with a traditional Chinese medicine combined with conventional medicine. Throughout the treatment, the patient received active conventional medical treatment, and traditional Chinese medicine interventions included tonifying qi, invigorating the spleen and transforming phlegm, promoting yang and eliminating stagnation, resolving dampness and dissipating phlegm, and promoting blood circulation and eliminating stasis. The main therapeutic principles adopted were to recuperating depleted yang and rescuing the patient from collapse and to resolve phlegm and promote water. Pogezilong Xuanbai Chengqi Decoction (破格子龙宣白承气汤) with modifications was administered. In summary, it is crucial to the timely adjust the immunosuppressive regimen, combine use of various anti-infective agents with a focus on COVID-19, to protect of cardiac and renal function, and to integrate traditional Chinese medicine in the entire treatment process. As this case is rare, the diagnostic and therapeutic methods in traditional Chinese medicine, the use of immunosuppressive agents, and follow-up monitoring strategies can be a valuable reference.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of percutaneous pedicle screw fixation combined expandable tubular retractor in the treatment of patients with spinal metastases.@*METHODS@#In the study, 12 patients of spinal metastases treated with percutaneous pedicle screw fixation combined expandable tubular retractor in our hospital were retrospectively reviewed between June 2017 and October 2019. Among the 12 patients, 9 were males and 3 were females; the median age was 62.5 years [(65.1±2.9) years]. The decompression segment of 7 patients was located at the lower thoracic spine (including 1 patient with incomplete paraplegia) and the decompression segment of 5 patients was located at the lumbar spine; Tomita score was 6.0±0.6. Perioperative data of the patients were reviewed. Visual analog scale (VAS score), Karnofsky score, and Eastern Cooperative Oncology Group (ECOG) score were compared before and after surgery. The patient's survival, adjuvant treatment, and internal fixation failure were observed in the follow-up period.@*RESULTS@#All the 12 patients had a successful operation with percuta-neous pedicle screw fixation combined expandable tubular retractor. The average operative time, blood loss, and blood transfused of the patients were (247.0±14.6) min, (804.2±222.3) mL and (500.0±100.0) mL, respectively. The average amount of drainage was (240.8±79.3) mL. Drainage tubes were pulled out early postoperative [(3.2±0.3) d], allowing early mobilization. The patients discharged (7.8±0.8) d postoperative. All the patients were followed up for 6-30 months, and the average overall survival time was (13.6±2.4) months. During the follow-up period, 2 patients experienced screw displacement, the internal fixation was stable after conservative treatment and no revision surgery was performed. The VAS of the patients was 7.1±0.2 before surgery, which decreased to 2.3±0.1 and 2.8±0.4 at 3 and 6 months after surgery (P < 0.05). The Karnofsky score of the patients was 59.2±1.9 before surgery, which increased to 75.0±1.9 and 74.2±3.1 at 3 and 6 months after surgery (P < 0.05). The ECOG of the patients was 2.3±0.2 before surgery, which decreased to 1.7±0.1 and 1.7±0.2 at 3 and 6 months after surgery (P < 0.05).@*CONCLUSION@#For selected patients with spinal metastases, minimally invasive surgical treatment of spinal metastases (percutaneous pedicle screw internal fixation combined with expandable tubular retractor) can effectively relieve the clinical symptoms and improve the quality of life, with satisfactory clinical outcome.

ABSTRACT

Bronchiectasis is characterized by a “vicious cycle” involving compromised host defense, mpaired clearance of airway mucus, bacterial colonization, infections, and inflammation, leading to frequent acute exacerbations and diminished quality of life. Based on the hypothesis of “vicious circle”, this paper explores the treatment of bronchiectasis by traditional Chinese medicine (TCM) from three aspects. Firstly, dissipating excessive “phlegm” secretion and enhancing airway clearance form the foundation of the treatment, aiming to improve the condition of mucus hypersecretion. Secondly, invigorating spleen for strengthening vital energy can improve the function of immune system and reduce recurrent infections and acute attacks. Lastly, clearing heat and purging the lung can alleviate infection and inflammatory damage. By employing these methods, TCM can disrupt the progression of the “vicious circle”, delaying disease advancement, minimizing acute exacerbations, and improving the quality of life for patients.

ABSTRACT

@#Since the first case of corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the end of 2019, the virus has spread rapidly around the world and has become a global public health problem. In the process of this virus epidemic, compared with the general population, cancer patients are considered to be highly susceptible people, especially the lung cancer patients. Some studies have shown that angiotensin converting enzyme 2 (ACE2) may be the pathway for SARS-CoV-2 to infect the host. At the same time, ACE2 is often abnormally expressed in non-small cell lung cancer. Therefore, understanding the respective mechanisms of ACE2 in COVID-19 and non-small cell lung cancer has extremely important reference value for the study of vaccines and therapeutic drugs, and also provides meaningful guidance for the protection of patients with lung cancer during the epidemic. This article reviews the possible invasive mechanism of ACE2 in SARS-CoV-2 and its abnormal expression in non-small cell lung cancer.

ABSTRACT

Objective:To explore the risk factors for the occurrence of thrombocytopenia (TCP) within 2 weeks after pediatric liver transplantation (LT) and examine the relationship between the occurrence of TCP and prognosis.Methods:From January 2021 to November 2021, clinical data were retrospectively reviewed for 162 pediatric LT recipients aged under 4 years at Organ Transplantation Center of Tianjin First Central Hospital.Based upon the lowest value of platelet count at Week 2 post-operation, they were assigned into two groups of TCP (n=90) and non-TCP (n=72). General preoperative profiles, intraoperative findings, postoperative complications, types of commonly used antibiotics, anticoagulant dosing and prognosis of two groups were compared.Univariate and multivariate analyses were utilized for examining the independent risk factors for TCP.Receiver operating characteristic (ROC) curve was plotted for examining the cut-off value of independent risk factors for diagnosing TCP.Results:Among them, 90 (55.56%) developed TCP within 2 weeks post-operation and 25(15.43%) developed TCP at Day 1 post-operation.The median preoperative platelet count was 178×10 9/L and the lowest value was 65×10 9/L at Day 3(1-4) post-operation with a declining rate of 63.5% and platelet count of recipient normalized at Day 6(4-7.25) post-operation.The results of univariate analysis showed statistically significant inter-group differences in operative duration[(574.43±80.53)min vs.(526.75±72.42)min], intraoperative blood loss[400(300, 550)ml vs.320(300, 400)ml], red blood cell transfusion[2(2, 3)U vs.2(1.5, 2.0)U], preoperative platelet count[178.5(141.75, 242.5)×10 9/L vs.257 (209.75, 357)×10 9/L], postoperative infection rate[27.8%(25/90)vs.13.9%(10/72)] and dosing rates of piperacillin sodium and tazobactam sodium[8.9%(8/90)vs.25.0%(18/72)] ( P<0.05). Multivariate Logistic regression analysis revealed statistically significant inter-group differences in operative duration( P=0.008), red blood cell transfusion( P=0.01), preoperative platelet count( P<0.01) and postoperative infection rate ( P=0.02). The results of ROC curve analysis showed that the cut-off values of operative duration, red blood cell transfusion and preoperative platelet count were 535 min, 2.75 U and 183.5×10 9/L respectively.Length of ICU stay was higher in TCP group than that in non-TCP group, and the difference was statistically significant [4(3, 5) vs.3(3, 4) day, P=0.006]. Conclusions:LT children aged under 4 years with intraoperative red blood cell transfusion>2.75 U, operative duration>535 min and preoperative platelet count<183.5×10 9/L are more likely to develop post-transplantation TCP.And occurrence of TCP prolongs the length of ICU stay in pediatric recipients.

ABSTRACT

Objective:To investigate the awareness of diabetes knowledge among the health examination population and its influencing factors.Methods:A cross-sectional study. From september to november 2022, the subjects of six health examination centers located in six different cities (Beijing, Shanghai, Tianjin, Chongqing, Xiamen, Hangzhou) in China were investigated in the form of questionnaires to investigate the awareness of diabetes core information and the level of trust to different information sources of diabetes knowledge. According to the questionnaire results, the subjects were divided into a high awareness group of diabetes core information and a low awareness group. Logistic regression was used to analyze the influencing factors of diabetes core information awareness; the t-test was used to compare the trust degree of the two groups to different information sources. Results:A total of 9 315 people were included in the six centers, including 4 932 men (52.90%) with an average age of (39.36±12.64) years and 4 383 women (47.10%) with a mean age of (37.47±11.85) years. Only 36% of the people had high awareness of diabetes core information; variables such as gender, age, education level, physical examination frequency in the past three years, package price of this physical examination, self-evaluation of diabetes knowledge, diabetes status, and city of residence were variables that affect the level of awareness of core information related to diabetes (all P<0.05). Compared with the low awareness group of diabetes core information, the high awareness group trusted professional medical staff ( t=-9.597, P<0.05) and community health promotion more ( t=-5.014, P<0.05), but did not trust the emerging popular science propaganda means, such as WeChat official accounts/WeChat groups/QQ groups, Internet web page, Tiktok/Kwai and other short video APPs. Conclusion:The awareness rate of diabetes knowledge among the health examination population is low, and it is affected by many factors; Health education on diabetes knowledge should be carried out for people undergoing physical examination.

ABSTRACT

Objective:To assess the ultrasonographic features and potential diseases of fetal abnormal sylvian fissure(SF), and to explore the value of whole-genome sequencing (WGS) in prenatal detection.Methods:A total of 28 fetuses with a sonographic diagnosis of abnormal SF in Shenzhen Maternal and Child Health Hospital Affiliated to Southern Medical University between October 2018 and October 2020 were prospectively included. The fetal brain was evaluated by neuroultrasound and intrauterine MRI in detail. Amniotic fluid/cord blood obtained by amniocentesis or tissue samples from umbilical cord after birth were collected for WGS. Pregnancy outcomes and postnatal MRI were recorded, and neurodevelopment of live-born infants was followed up for more than 24 months after delivery.Results:During the study period, 28 fetuses with abnormal SF were identified, with a gestational age of 21.3-30.0 (24.8±2.0) weeks. Abnormal SF presented in MCD ( n=15, 53.6%), chromosomal anomalies ( n=3, 10.7%) or single-gene genetic syndromes ( n=3, 10.7%) with the affected fetuses showing developmental delay, hydrocephalus or leukomalacia ( n=4, 14.2%), corpus callosal agenesis with large interhemispheric cysts ( n=1, 3.6%), benign subarachnoid space enlargement with arachnoid cysts ( n=1, 3.6%), and multiple malformations ( n=1, 3.6%). Among the 15 cases with MCD, the most common pathology was lissencephaly/pachygyria, followed by schizencephaly, severe microcephaly, hemimegalencephaly with paraventricular heterotopia, and polymicrogyria. Abnormal SF presented bilaterally in 23 fetuses and unilaterally in 5. All cases were categorized into six types depending on SF morphology in the transthalamic section: no plateau-like or a small insula, linear type, irregular corrugated SF, Z-shaped, and cyst occupying type. In addition to abnormal SF, associated anomalies or mild variations were identified in all fetuses. There were 17 cases underwent intrauterine MRI, and 13 cases underwent postnatal MRI examination.And 25 pregnancies were terminated; 3 were born alive, and 2 had typical syndromic changes with poor neurodevelopmental prognosis. A related pathogenic genetic variant was detected in 57.1% (16/28) fetus, and the incidence of single nucleotide variants(SNVs) was 42.9% (12/28), among which de novo SNVs accounted for 91.7% (11/12). Conclusions:Fetal abnormal SF could be classified based on the ultrasonographic features of transthalamic section. Fetal abnormal SF may indicate MCD, some chromosomal abnormalities or single-gene genetic syndromes that may lead to poor neurodevelopmental outcomes, and may be affected by extra-cortical factors. It is suggested to carry out targeted prenatal genetic diagnosis for fetuses with abnormal SF.

ABSTRACT

Objective:To investigate the clinical efficacy of vitamin D drops combined with insulin aspart in the treatment of gestational diabetes mellitus (GDM), and the effect of vitamin D drops on the serum levels of 1, 25 dihydroxyvitamin D 3 [1, 25(OH) 2D 3] and retinol binding protein 4 (RBP4). Methods:A total of 94 GDM patients admitted to the Baoding Second Central Hospital from March 2019 to March 2021 were selected and randomly divided into an observation group and a control group with 47 cases each using a random number table method. The control group received subcutaneous injection of insulin aspartate for treatment, while the observation group received oral vitamin D drops for treatment. After 4 weeks of continuous treatment, the blood glucose control effect and adverse reactions were observed in both groups. The glucose metabolism indicators of the two groups were compared before and after treatment, including fasting blood glucose (FPG), 2-hour postprandial blood glucose (2-hour PG), insulin resistance index (HOMA-IR), and pancreatic islets β Cell Function Index (HOMA-β) and serum levels of 1, 25(OH) 2D 3, RBP4, lipoprotein related phospholipase A2 (Lp-PLA2), and vascular cell adhesion molecule-1 (VCAM-1). All patients were followed up until the end of pregnancy, and Statistical analysis was conducted on the adverse outcomes of two groups of mothers and infants. Results:The time to reach the standard for FPG and 2-hour PG in the observation group, as well as the time for both to reach the standard were significantly shorter than those in the control group (all P<0.05). There was no statistically significant difference in the incidence of dawn phenomenon and hypoglycemia between the observation group and the control group (all P>0.05). After treatment, FPG and 2-hour PG in both groups were significantly reduced compared to those before treatment (all P<0.05); However, after treatment, there was no statistically significant difference between the groups (all P>0.05). Compared with before treatment, HOMA-IR in both groups significantly decreased (all P<0.05), All HOMA- β significantly increased (all P<0.05); And the improvement was more significant in the observation group (all P<0.05). After treatment, the serum levels of 1, 25(OH) 2D 3 in the observation group significantly increased compared to that before treatment ( P<0.05), but there was no significant change in the control group before and after treatment ( P>0.05). After treatment, the levels of serum RBP4, Lp-PLA2, and VCAM-1 in both groups significantly decreased compared to those before treatment (all P<0.05); After treatment, the serum levels of RBP4, Lp-PLA2, and VCAM-1 in the observation group were lower than those in the control group (all P<0.05). The incidence of adverse maternal and neonatal outcomes in the observation group was 14.9%(7/47) and 10.6%(5/47), respectively, which were lower than those in the control group [34.0%(16/47) and 27.7%(13/47)] (all P<0.05). There were 8 cases of hypoglycemia in 94 patients (3 in the observation group and 5 in the control group), and no other adverse events occurred. Conclusions:The combination of vitamin D drops and insulin aspartate in the treatment of GDM can safely, effectively, quickly, and steadily control patients′ blood sugar, improve IR and pancreatic islets β The effect of cell function on reducing the incidence of adverse maternal and fetal outcomes may be related to increasing serum 1, 25(OH) 2D 3 levels and down-regulating the expression levels of serum RBP4, Lp-PLA2, and VCAM-1.

ABSTRACT

Objective:To summarize literature of risk prediction models for catheter-related thrombosis in PICC at home and abroad, in order to provide reference for the development and improvement of risk prediction models for PICC catheter-related thrombosis (PICC-CRT) and the selection and use of medical staff.Methods:All studies on the risk prediction model of PICC-CRT were systematically searched in the Chinese and English literature database from June 2012 to June 2022. Two researchers independently screened the literature and extracted the data. The prediction model risk of bias assessment tool was used to evaluate the bias risk and applicability of the included literature.Results:A total of 13 articles were included, including 1 multicenter study and 12 single-center studies. Eight literatures were retrospective studies and five were prospective studies. Bias risk assessment showed that there was a bias risk in all the 6 studies. In terms of applicability evaluation, the 13 studies had good applicability in all fields and overall.Conclusions:There were various types of PICC catheter-related thrombosis risk assessment models, which had good predictive efficiency, but there was also a high risk of bias in these studies. The important contents of PICC catheter-related thrombosis risk prediction model are patient factors and treatment factors. In the future, the existing models need to be validated and improved, or a prediction model with low risk of bias should be constructed to effectively prevent PICC-CRT.

ABSTRACT

Objective:To observe the clinical effect of Sanhuang Qingre Fuming and Washing Decoction combined with Chinese medical excision in the treatment of horseshoe-shaped perianal abscess after high position and to explore its mechanism of action.Methods:Randomized controlled trial. Sixty surgical patients in our hospital from April 2020 to February 2021 were selected as observation objects. The patients were divided into two groups according to the random number table, with 30 patients in each group. Both groups were treated with Traditional Chinese Medicine drainage. On the second day after operation, the control group was treated with potassium permanganate sitz bath fumigation and washing, and the observation group was treated with Sanhuang Qingre Fuming and Washing Decoction. The wound healing time was observed in the two groups, serum TNF-α, IL-1β, IL-6, VEGF, bFGF, and EGF levels were detected by ELISA on the 1st and 7th d after operation, respectively. Serum SOD level was detected by the chemiluminescence method, and serum MDA level was detected by thiobarbituric acid method.Results:The wound healing time in the observation group was shorter than that in the control group ( t=3.37, P<0.01). The recovery rate was 93.3% (28/30) in the observation group and 76.7% (23/30) in the control group. The difference was statistically significant between the two groups ( χ2=4.32, P=0.038). Seven days after surgery, the levels of serum TNF-α, IL-1β and IL-6 in the observation group were significantly lower than those in the control group ( t values were 2.01, 2.05 and 4.88, respectively, P<0.05 or P<0.01), the level of SOD was significantly higher than that of the control group ( t=-2.13, P=0.038), the level of MDA water was significantly lower than that of the control group ( t=3.26, P=0.002), and the levels of VEGF, bFGF and EGF were significantly higher than those in the control group ( t values were -2.02, -3.33, -3.77, respectively, P<0.05). Conclusion:Sanhuang Qingre Tuming and Washing Decoction combined with Chinese medical excision in the treatment could shorten the healing time of the wound surface of horseshoe-shaped perianal abscess after high elevation and improve the recovery rate. The Sanhuang Qingre Fuming and Washing Decoction may reduce inflammatory reaction and oxidative stress damage, improve the level of growth factors and facilitate the postoperative tissue repair.

ABSTRACT

【Objective】 To investigate the effects of miR-126-3p targeting chemokine receptor 1 (CCR1) in exosomes derived from bone marrow mesenchymal stem cells (BMSC) on the proliferation, migration, and invasion of lung cancer cells. 【Methods】 BMSC cells were cultured; exosomes were extracted and identified by the exosomal marker proteins CD63 and TSG101. After exosome culture of A549 cells for different durations (0, 24, 48, and 72 h), cell survival rate was detected by CCK-8, mRNA levels of miR-126-3p and CCR1 were detected by qRT-PCR, and cell migration and invasion abilities were detected by Transwell assay. The relative expressions of CCR1, epithelial cadherin (E-cad), neural cadherin (N-cadherin), and Vimentin were detected by Western blotting. 【Results】 Exosomes had round or oval cup-shaped structures with bright edges and dark middle, with a particle size distribution of about 152 nm, expressing CD63 and TSG101 proteins. The expression of miR-126-3p in exosomes was higher than that in A549 cells. The expression of miR-126-3p was low in A549 cells and that of CCR1 mRNA was high. However, after co-culture with exosomes, the expression of miR-126-3p in A549 cells was increased, while the expression of CCR1 was decreased. A549 cells were cocultured with exosomes for 0, 24, 48, and 72 h. The survival rate, migration and invasion abilities, CCR1 gene and protein expression levels, and N-cad and Vimentin protein expression levels of A549 cells decreased gradually with the extension of culture time. The level of miR-126-3p and the expression of E-cad protein increased gradually with the extension of culture time. 【Conclusion】 The co-culture of exosomes derived from bone marrow mesenchymal stem cells with A549 cells can increase the expression level of miR-126-3p, and miR-126-3p can reduce the proliferation, migration, and invasion of A549 cells by targeting the inhibition of CCR1 expression.

ABSTRACT

OBJECTIVE@#To analyze the efficacy of Biejiajian Pill (BJJP) on intestinal microbiota in patients with hepatitis B cirrhosis/liver fibrosis, and explore its relationship with liver fibrosis.@*METHODS@#This was a prospective, randomized double-blind controlled trial. Using the stratified block randomization method, 35 patients with hepatitis B liver cirrhosis/liver fibrosis were randomly assigned (1:1) to receive entecavir (0.5 mg/d) combined with BJJP (3 g/time, 3 times a day) or placebo (simulator as control, SC group, simulator 3 g/time, 3 times a day) for 48 weeks. Blood and stool samples were collected from patients at baseline and week 48 of treatment, respectively. Liver and renal functions as well as hematological indices were detected. Fecal samples were analyzed by 16S rDNA V3-V4 high-throughput sequencing, and intestinal microbiota changes in both groups before and after treatment were compared, and their correlations with liver fibrosis were analyzed.@*RESULTS@#Compared with the SC group, there was no significant difference in liver function, renal function and hematology indices in the BJJP group, however, the improvement rate of liver fibrosis was higher in the BJJP group (94.4% vs. 64.7%, P=0.041). Principal coordinate analysis (PCoA) based on weighted Unifrac distance showed significant differences in intestinal microbiota community diversity before and after BJJP treatment (P<0.01 and P=0.003), respectively. After 48 weeks' treatment, the abundance levels of beneficial bacteria (Bifidobacteria, Lactobacillus, Faecalibacterium and Blautia) increased, whereas the abundance levels of potential pathogenic bacteria, including Escherichia coli, Bacteroides, Ruminococcus, Parabacteroides and Prevotella decreased, among which Ruminococcus and Parabacteroides were significantly positively correlated with degree of liver fibrosis (r=0.34, P=0.04; r=0.38, P=0.02), respectively. The microbiota in the SC group did not change significantly throughout the whole process of treatment.@*CONCLUSION@#BJJP had a certain regulatory effect on intestinal microbiota of patients with hepatitis B cirrhosis/liver fibrosis (ChiCTR1800016801).
