ABSTRACT

The lymphatic system, as well as pathological changes of the lymphatic system, underlies the progress of an array of diseases and conditions, including cancer, inflammation and autoimmune disorders, infectious diseases and metabolic syndrome. A variety of biological targets in the lymphatic system can be employed to modulate these high-burden diseases, and the pharmacokinetics and drug delivery strategies in the context of lymphatics are of critical importance to optimise drug exposure to lymphatic-related targets. As such, research and drug development in this field has gained increasing attention in recent years. This article aims to provide an overview of pharmaceutical research with a focus on the lymphatic system and therapeutic targets within the lymphatics, followed by lymphatic drug delivery approaches, which may be of interest for researchers in academia, pharmaceutical industry and regulatory sciences.

ABSTRACT

Early diagnosis of acute rejection is of significance for the protection of renal allograft function. Pathological puncture biopsy is the gold standard for the diagnosis of acute rejection of renal allografts. Nevertheless, it may provoke multiple complications, such as bleeding, infection and renal parenchymal injury, which limit its widespread application. In recent years, the sensitivity of contrast-enhanced ultrasound in the diagnosis of acute rejection has been constantly improved. Ultrasound-targeted microbubble technique has further enhanced the diagnostic specificity of contrast-enhanced ultrasound, making it possible to replace pathological puncture biopsy. Besides, in the field of acute rejection treatment, microbubble ultrasonic cavitation may promote local delivery of immunosuppressants by inducing sonoporation and exhibit anti-rejection effect. In this article, the application of contrast-enhanced ultrasound in the diagnosis and treatment of acute rejection after kidney transplantation was reviewed, aiming to provide reference for widespread application of contrast-enhanced ultrasound in kidney transplantation.

ABSTRACT

Type 2 diabetes mellitus (T2DM) is a heterogeneous disease with insulin deficiency and insulin resistance (IR) as the main etiology and is often accompanied by complications. Volatile oil is a volatile oily liquid extracted from natural plants, which has many pharmacological effects such as regulating Qi, relieving pain, inhibiting bacteria, and reducing inflammation. In recent years, there have been numerous reports on the treatment of T2DM by natural plant volatile oil and its effective components, which has become one of the new directions in the treatment of T2DM. With natural plant essential oil and its active components as the starting point, this paper comprehensively analyzed and summarized the material basis, mechanism, and signaling pathways of essential oil in the treatment of T2DM and its complications in China and abroad in recent years, and focused on the inhibitory effect of essential oil and its active components, such as carvacrol, paeonol, and β-caryophylene, on IR to improve T2DM by protecting pancreatic β-cells, inhibiting α-glucosidase activity, regulating the abundance and diversity of intestinal microbiota, and regulating glucose transporter protein type4 (GLUT4), adenylate 5′-monophosphate-activated protein kinase (AMPK), phosphatidylinositol-3 kinase (PI3K)/protein kinase B (Akt) signaling pathways to provide some references for the volatile oil intervention in T2DM and the development of new green antidiabetic drugs.

ABSTRACT

Neuroendocrine carcinoma(NEC) is a malignant tumor derived from neuroendocrine cells, with distinct clinical, morphological and immunohistochemical characteristics. Neuroendocrine carcinoma of the head and neck is very rare in clinic. Larynx is the most common affected site, and the root of the tongue is extremely rare. The clinical manifestations are mainly eating pain, cauliflower like mass in the mouth, and ulcerative lesions that have not healed for a long time. Maxillofacial MRI and contrastenhanced CT are the most commonly used examination tools for such diseases, which can detect the spaceoccupying lesions of tumors. Neuroendocrine granules found in the cytoplasm under pathological light microscope can be diagnosed as neuroendocrine carcinoma. However, for most cases, it is difficult to make a diagnosis only under light microscope, and it is often necessary to make a diagnosis by means of immunohistochemistry and other technical means. This paper reports a case of neuroendocrine carcinoma of the root of the tongue, introduces its characteristics, diagnosis and treatment, and reviews the relevant literature of this case.

ABSTRACT

Purpose@#This study was aimed to investigate long-term survivals and toxicities of early-stage nasopharyngeal carcinoma (NPC) in endemic area, evaluating the role of chemotherapy in stage II patients. @*Materials and Methods@#Totally 187 patients with newly diagnosed NPC and restaged American Joint Committee on Cancer/ International Union Against Cancer 8th T1-2N0-1M0 were retrospectively recruited. All received intensity-modulated radiotherapy (IMRT)±chemotherapy (CT) from 2001 to 2010. @*Results@#With 15.7-year median follow-up, 10-year locoregional recurrence-free survival, distant metastasis-free survival (DMFS), disease-specific survival (DSS), and overall survival (OS) were 93.3%, 93.5%, 92.9% and 88.2%, respectively. Multivariable analyses showed cervical lymph nodes positive and pre-treatment prognostic nutritional index ≥ 52.0 could independently predict DMFS (p=0.036 and p=0.011), DSS (p=0.014 and p=0.026), and OS (p=0.002 and p 45 years (p=0.002) and pre-treatment lactate dehydrogenase ≥ 240 U/L (p 0.05). Unsurprising, patients in IMRT+CT had more acute gastrointestinal reaction, myelosuppression, mucositis, late ear toxicity, and cranial nerve injury (all p < 0.05) than IMRT alone group. @*Conclusion@#Superior tumor control and satisfying long-term outcomes could be achieved with IMRT in early-stage NPC with mild late toxicities. As CT would bring more toxicities, it should be carefully performed to stage II patients.

ABSTRACT

Patients infected with human immunodeficiency virus (HIV) are prone to renal insufficiency, which may progress into end-stage renal disease (ESRD). HIV infection has been previously considered as an absolute contraindication of transplantation. The lives of HIV-positive ESRD patients can only maintained through dialysis. With the development of medicine, transplantation practitioners at home and abroad attempt to perform kidney transplantation in HIV-positive patients. Whether kidney transplantation is feasible for HIV-positive patients, whether HIV-positive donor kidneys can be used for transplantation, and the efficacy of kidney transplantation for HIV-positive patients has always been hot topics in the field of transplantation. In this article, HIV-associated nephropathy, the conditions of kidney transplantation for HIV-positive patients, the efficacy of kidney transplantation for HIV-positive patients, use of HIV-positive donor kidneys, use of immune-inducing drugs and postoperative use of immunosuppressants for HIV-positive patients were illustrated, aiming to provide reference for kidney transplantation for HIV-positive patients in clinical practice, application of HIV-positive donor kidneys and postoperative management of HIV-positive patients.

ABSTRACT

Objective:To access the clinical efficacy and safety of hydroxychloroquine (HCQ) in treatment of IgA nephropathy (IgAN).Methods:The data of IgAN patients who were diagnosed by renal biopsy in the First Affiliated Hospital, College of Medicine, Zhejiang University from May 2016 to August 2020 and had been treated with HCQ for more than 6 months without other immunosuppressants were retrospectively analyzed. The efficacy and side effects were compared between groups according to the baseline urine protein/creatinine ratio (UPCR) or whether combined with renin-angiotensin-aldosterone system inhibitor (RAASi).Results:A total of 121 patients were enrolled, including 45 males (37.19%). At baseline, the median UPCR was 0.69(0.45, 1.00) g/g; the median estimated glomerular filtration rate (eGFR) was 93.46(73.14, 115.67) ml·min -1·(1.73 m 2) -1; the median serum creatinine was 80.00(61.00, 98.00) μmol/L, and the serum albumin was (44.39±3.36) g/L. After HCQ treatment, UPCR and red blood cells were significantly decreased compared with baseline (all P<0.05). Triglyceride, total cholesterol and low-density lipoprotein cholesterol were also significantly decreased during the follow-up period. Serum creatinine, eGFR, serum albumin and serum uric acid remained stable. After 6 months of follow-up, the total remission rate was 56.88%, including 15.60% of partial remission and 41.28% of complete remission; at the end of follow-up, the median follow-up time was 280.00(214.00, 411.00) days and the total remission rate was 56.20%, including 9.92% of partial remission and 46.28% of complete remission. Group analysis showed that the remission rate was 60.53% ( n=76) and 48.48% ( n=33) at 6 months (Mann-Whitney U test, Z=-2.331, P=0.020) and 57.65% ( n=85) and 52.78% ( n=36) at the end of follow-up (Mann-Whitney U test, Z=-1.673, P=0.094) between patients with baseline UPCR<1 g/g and patients with baseline UPCR≥1 g/g; and the remission rate was 66.67% ( n=30) and 53.16% ( n=79) at 6 months (Mann-Whitney U test, Z=1.062, P=0.288) and 61.29% ( n=31) and 54.44% ( n=90) at the end of follow-up (Mann-Whitney U test, Z=0.930, P=0.352) between patients with single HCQ and patients with HCQ+RAASi. For side effects, the eGFR of 2 patients decreased by more than 30% compared with baseline, 1 patient relapsed and 1 patient developed blurred vision. Conclusions:HCQ is safe and effective for the treatment of IgAN.

ABSTRACT

Cancer immunotherapy has become a new generation of anti-tumor treatment, but its indications still focus on several types of tumors that are sensitive to the immune system. Therefore, effective strategies that can expand its indications and enhance its efficiency become the key element for the further development of cancer immunotherapy. Natural products are reported to have this effect on cancer immunotherapy, including cancer vaccines, immune-check points inhibitors, and adoptive immune-cells therapy. And the mechanism of that is mainly attributed to the remodeling of the tumor-immunosuppressive microenvironment, which is the key factor that assists tumor to avoid the recognition and attack from immune system and cancer immunotherapy. Therefore, this review summarizes and concludes the natural products that reportedly improve cancer immunotherapy and investigates the mechanism. And we found that saponins, polysaccharides, and flavonoids are mainly three categories of natural products, which reflected significant effects combined with cancer immunotherapy through reversing the tumor-immunosuppressive microenvironment. Besides, this review also collected the studies about nano-technology used to improve the disadvantages of natural products. All of these studies showed the great potential of natural products in cancer immunotherapy.

ABSTRACT

Objective:To establish an automatic planning method using volumetric-modulated arc therapy (VMAT) for primary liver cancer (PLC) radiotherapy based on predicting the feasibility dose-volume histogram (DVH) and evaluate its performance.Methods:Ten patients with PLC were randomly chosen in this retrospective study. Pinnacle Auto-Planning was used to design the VMAT automatic plan, and the feasibility DVH curve was obtained through the PlanIQ dose prediction, and the initial optimization objectives of the automatic plan were set according to the displayed feasible objectives interval. The plans were accessed according to dosimetric parameters of the planning target volume and organs at risk as well as the monitor units. All patients′ automatic plans were compared with clinically accepted manual plans by using the paired t-test. Results:There was no significant difference of the planning target volume D 2%, D 98%, D mean or homogeneity index between the automatic and manual plans ((58.55±2.81) Gy vs.(57.98±4.17) Gy, (47.15±1.58) Gy vs.(47.82±1.38) Gy, (53.14±0.95) Gy vs.(53.44±1.67) Gy and 1.15±0.05 vs. 1.14±0.07, all P>0.05). The planning target volume conformity index of the manual plan was slightly higher than that of the automatic plan (0.77±0.08 vs. 0.69±0.06, P<0.05). The mean doses of normal liver, V 30Gy, V 20Gy, V 10Gy, V 5Gy and V< 5Gy of the automatic plan were significantly better than those of the manual plan ((26.68±11.13)% vs.(28.00±10.95)%, (29.96±11.50)% vs.(31.89±11.51)%, (34.88±11.51)% vs.(38.66±11.67)%, (45.38±12.40)% vs.(50.74±13.56)%, and (628.52±191.80) cm 3vs.(563.15±188.39) cm 3, all P<0.05). The mean doses of the small intestine, the duodenum, and the heart, as well as lung V 10 of the automatic plan were significantly less than those of the manual plan ((1.83±2.17) Gy vs.(2.37±2.81) Gy, (9.15±9.36) Gy vs.(11.18±10.49) Gy, and (5.44±3.10) Gy vs.(6.25±3.26) Gy, as well as (12.70±7.08)% vs.(14.47±8.11)%, all P<0.05). Monitor units did not significantly differ between two plans ((710.67±163.72) MU vs.(707.53±155.89) MU, P>0.05). Conclusions:The automatic planning method using VMAT for PLC radiotherapy based on predicting the feasibility DVH enhances the quality for PLC plans, especially in terms of normal liver sparing. Besides, it also has advantages for the protection of the intestine, whole lung and heart.

ABSTRACT

Objective@#To explore the effects of auricular point stimulation on constipation among college students and to provide a reference for improving constipation among college students.@*Methods@#Between September 15 and September 30, 2019, the International Nursing College of Hainan Medical College Nursing School Survey, which included the constipation assessment scale (CAS), was conducted among 603 female college students. There were 90 cases of functional constipation, which were divided into a control group and an observation group of 45 cases each using the random number table method. The control group was given health education and behavioral guidance, such as a diet intervention, an exercise intervention, an emotional management intervention, and guidance on defecation habits, etc, via WeChat. The observation group received auricular stimulation intervention in addition to the control group measures. Before and two weeks after the intervention, the Wexner constipation and the Patient Assessment of Constipation Quality of Life (PAC-QOL) scales were used to assess the effect of auricular stimulation on students with constipation.@*Results@#Before intervention, there was no significant difference in the Wexner constipation scores between the two groups (P>0.05). After the intervention, the Wexner constipation scores in the observation group were lower than those in the control group, and the differences were statistically significant (t=8.38, 8.95, 11.96, 9.08, 6.45, 13.18, 11.93, 6.19, P<0.05). Before intervention, there was no statistically significant difference in PAC-QOL score between the two groups (P>0.05). After intervention, the difference in the control group s PAC-QOL scores on all dimensions and total dimension score lower earlier, was statistically significant (t=5.29, 6.64, 10.28, 7.81, 9.60, P<0.01). The observation group s PAC-QOL scores after the intervention were lower compared to before the intervention (t=7.98, 11.81, 11.44, 6.93, 8.81, P<0.01), and the difference was statistically significant. All individual and total dimension scores of the observation group and the control group were significantly lower than those of the control group, and the difference was statistically significant(P<0.05).@*Conclusion@#Auricular stimulation of TCM can significantly improve the constipation score of college students and improve their quality of life.

ABSTRACT

Objective:To provide standardized and normalized first aid simulation training for trainees, and to enhance the level of first aid knowledge and operational capacity.Methods:Based on the first aid training course of American Heart Association, we set up the faculty of first aid simulation training teachers in the hospital. In accordance with the established teaching contents, procedures and forms, the instructor conducted standardized first aid simulation training for residents in the skill center of the hospital by using unified training and video materials. Before and after the training, students' theoretical and operational skills were assessed, and questionnaires were conducted among them after the training. SPSS 19.0 was used for data analysis, and paired data bilateral t test was used for statistical analysis. Results:No matter the theory test or the skill test, the results after the training were obviously better than those before the training, with statistical differences ( P < 0.05). The post-training survey showed that 100 percent of the participants believed that professional knowledge has been strengthened and first-aid skills have been improved through the training. Conclusion:Standardized first aid simulation training based on the American Heart Association helps to improve the comprehensive first aid ability of trainees.

ABSTRACT

Objective:To screen the neutralizing epitope of enterovirus 71 (EV71) and determine the specific minimum amino acid sequence that triggers immunity for providing a theoretical basis for the development of synthetic peptide vaccines.Methods:EV71 neutralizing antibody-specific binding clones were panned and sequenced using a phage display random 12-peptide library to obtain the key sequences of neutralizing epitopes. A series of peptides containing the key sequences with N-terminal acetylation (AC) and C-terminal linking to Keyhole limpet hemocyanin (KLH) were synthesized. Serum samples were collected after immunizing mice with the modified peptides. Then the immunogenicity of the peptides and the neutralizing activity of serum samples were analyzed by Western blot, ELISA and neutralization test.Results:After three rounds of panning, cloning and sequencing, KQEKDL was identified as the key motif. The serum samples collected from the mice immunized with the modified series of peptides containing key motifs had different degrees of binding ability to EV71 and VP1 protein. The serum samples of mice immunized the synthetic peptide containing only the minimum key motif (AC-KQEKDL-KLH) had the strongest response to the other three peptides and EV71 and the highest neutralizing titer.Conclusions:The EV71 neutralizing epitope was successfully screened using the phage display random peptide library. The key motif of KQEKDL might be the specific minimum amino acid sequence that triggered the immune system. This study provides a theoretical basis for better understanding the immune response mechanism, evaluating the immunogenicity of the antigens and further research and development of polypeptide vaccines.

ABSTRACT

Objective:To explore whether there were changes in midbrain morphology related to motor function in patients with cerebral small vessel disease (CSVD).Methods:The study was conducted on a subset of patients with CSVD registered at the Department of Neurology of Peking Union Medical College Hospital from 2010 to 2018. All magnetic resonance imaging images were taken with a 3.0 T nuclear magnetic resonance imager. The measurement of anteroposterior diameter of the mesencephalon and the tegmentum of mesencephalon was performed on a personal computer with the image processing software RadiAnt DICOM Viewer. Several clinical manifestations of dyspraxia, dysphagia, dysarthria and dysuria were evaluated by interviewing the patient and family members living with the patient. Kinect depth camera combined with self-developed software platform was used to conduct quantitative evaluation of patients′ motor function. Three parameters, namely walking speed, walking time of three meters and time of standing up and sitting down, were selected from the obtained parameters. SPSS 17.0 software was used for statistical analysis.Results:A total of 176 patients were included, aged 30-88 (64.16±11.57) years. One hundred and fifteen patients were males, accounting for 65.34%. In patients with CSVD, anteroposterior diameter of the mesencephalon and the tegmentum of mesencephalon were negatively correlated with age ( B=-0.032, P<0.001; B=-0.020, P=0.006). The anteroposterior diameter of the mesencephalon was negatively correlated with symptoms of dyskinesia ( OR=0.006, 95% CI 0-0.135, P=0.001), even when the age and gender were adjusted ( OR=0.014,95% CI 0-0.416, P=0.013). The anteroposterior diameter of the mesencephalon was negatively correlated with symptoms of dysuria ( OR=0.046,95% CI 0.002-0.936, P=0.045), but no longer correlated when the age and gender were adjusted. The anteroposterior diameter of tegmentum of mesencephalo was also negatively correlated with symptoms of dyskinesia ( OR=0.035,95% CI 0.002-0.684, P=0.027), but no longer correlated after adjusting for age and gender. Video recording and evaluation of motor function were performed on 87 patients. Spearman correlation analysis showed that none of the three motor function scores was correlated with age or gender. The anteroposteric diameter of the midbrain was positively correlated with walking speed ( r=0.231 ,P=0.040) and negatively correlated with walking time of three meters ( r=-0.304, P=0.005), but not with standing up and sitting down time, while the anteroposteric diameter of tegmentum of mesencephalo was not correlated with all of them. Conclusion:There are changes in mesencephalon morphology in patients with CSVD, structural parameters of mesencephalon are related to motor function and urination function, and mesencephalon atrophy may be an independent related factor for symptoms of dyskinesia in patients with CSVD.

ABSTRACT

Objective:To analyze the clinical characteristics of patients suffering from acute ischemic stroke (AIS) complicated with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods:Data of patients with AIS who visited the Second Affiliated Hospital of Soochow University from January 2015 to June 2020 and underwent polysomnography monitoring (PSG) in the sleep center were collected retrospectively. Patients were divided into OSAHS group and AIS only group. Demographic information of patients, general clinical data, hematological indicators of glucose and lipid metabolism and inflammatory markers, PSG parameters and neurological function scores were collected, including the National Institutes of Health Stroke Scale (NIHSS) on admission and the modified Rankin Scale (mRS) on discharge. We compared the differences between the two groups. In addition, OSAHS group were divided into good prognosis and poor prognosis subgroups according to mRS score. The differences between the two subgroups were compared.Results:A total of 112 AIS patients combined with OSAHS and 89 AIS only patients were included. The proportion of non-rapid eye movement stages 1+2 [(N1+N2) %], arousal index, the oxygen desaturation index (ODI), percentage of total sleep time with oxygen saturation<90% (TS90) in the OSAHS group were higher than those in the AIS only group, while N3%, lowest nocturnal oxygen saturation (LSaO 2) were lower (all P<0.05). There was no statistical difference in the distribution of cerebral apoplexy lesions (cortex, subcortical, brainstem, cerebellum) between the two groups, but the proportion of patients with multifocal cerebral apoplexy in the OSAHS group was higher ( P=0.032). There was no statistical difference in NIHSS score on admission between the two groups, but the neutrophil/lymphocyte ratio (NLR) score ( P=0.004) and mRS score on discharge ( P=0.010) of the OSAHS group were significantly higher than those in the AIS only group. There were 74 patients in the good prognosis group and 38 in the poor prognosis group. The analysis showed that the NIHSS and NLR scores of the poor prognosis group were higher than the good prognosis group, admission NIHSS score was a risk factor for poor prognosis, all P<0.01. Conclusions:AIS patients complicated with OSAHS are characterized by disordered sleep structure, more severe nocturnal hypoxia, higher risk of developing multiple lesions, poor neurological function recovery at discharge, and high inflammatory index of NLR. Among them, patients with poor prognosis have poorer sleep efficiency, and high admission NIHSS score is a risk factor for poor prognosis.

The Kaplan-Meier method was used to calculate the cumulative incidence of patients' remission.Results:There were 13 patients enrolled, including 8 females, and aged (35.23±15.92) years old. The urinary protein/creatinine ratio was (5.22±1.57) g/g before rituximab treatment. Four patients were on dialysis at admission, and 9 patients without dialysis had serum creatinine of (223.22±85.73) μmol/L. Eight patients were confirmed as proliferative lupus nephritis by renal biopsies, including 7 cases with crescent formation and 1 case with thrombotic microangiopathy (TMA), and the other 5 cases without renal biopsies were clinically diagnosed as TMA. The dose of rituximab was (815±516) mg (200-2 100 mg), and all the patients reached the state of peripheral blood B cells clearance (CD19 + B cell count was<5/μl). After the first treatment of rituximab, the median time to B-cell clearance was 21(15, 35) days, and 8 patients reached B-cell depletion (CD19 + B cell count was 0). The remission rate was 12/13 (two cases reached complete remission, and 10 cases reached partial remission). Three cases stopped dialysis, and 1 case (with glomerulosclerosis of 52.94%) entered maintaining dialysis. The relapse times in the maintenance remission period of 7 patients with refractory lupus nephritis declined significantly from (1.57±0.53) times in a median history of 60(20, 109) months to (0.43±0.79) times in a median history of 18(10, 23) months after the use of rituximab ( P=0.015). After using rituximab, the incidence of infection was 7/13. The median time from the use of rituximab to infection was 26(4, 44) days. Pulmonary infection (5/13) was the most common type and all infected patients recovered after anti-infection treatment. Conclusions:Rituximab can be used in the treatment of active lupus nephritis with AKI, especially in patients with crescent formation and TMA, but the infection should be paid close attention to and prevented.
