ABSTRACT

Objective:This study aims to investigate the clinical efficacy of Modified Xiangsha Liu Junzitang in the treatment of diabetic gastroparesis (DGP) and its influence on gastrointestinal hormones and oxidative stress. Method:In this study, 128 patients were randomly divided into control group (64 cases) and observation group (64 cases) . Patients in two groups took domperidone tablets orally 30 minutes before meals, 10 mg/time, 3 times/day. Patients in control group took Shenling Baizhusan San, 6 g/time, twice a day. Patients in observation group were prescribed addition and subtraction therapy of Modified Xiangsha Liu Junzitang, 1 dose/day. The course of treatment for both groups was 4 weeks. Before and after treatment, scores of gastroparesis cardinal symptom index (GCSI), and gastric emptying test and electrogastrogram were noted. Before the treatment, scores of traditional Chinese medicine (TCM) syndrome and health survey summary were graded(SF-36). The levels of gastrin (GAS), motilin (MTL), vasoactive intestinal peptide (VIP), somatostatin (SS), superoxide dismutase (SOD), reactive oxygen species (ROS) and malondialdehyde (MDA) were measured before and after treatment. And adverse reactions during treatment were recorded. Result:The scores of postprandial abdominal distension/early satiety, nausea and vomiting, abdominal distention and the total scores of GCSI in the observation group were lower than those in control group (<italic>P</italic><0.01). The gastric emptying rate in observation group was higher than that in control group (<italic>P</italic><0.01), and the score of TCM syndromes was lower than that of control group (<italic>P</italic><0.01). The scores of SF-36 in observation group were higher than those in control group (<italic>P</italic><0.01). The frequency of gastric electricity and gastric electric vibration before and after the meal in observation group were higher than that in control group (<italic>P</italic><0.01). The levels of GAS, MTL, VIP, ROS and MDA in observation group were lower than those in control group (<italic>P</italic><0.01), while the levels of SS and SOD were higher than that of control group (<italic>P</italic><0.01). The total effective rate in observation group was 93.75% (60/64), which was higher than 79.69% (51/64) (<italic>χ</italic><sup>2</sup>=5.494, <italic>P</italic><0.05) in control group (<italic>P</italic><0.01). And no adverse reactions were found in the clinical observation. Conclusion:Modified Xiangsha Liu Junzitang combined with prokinetic drugs in the treatment of DGP patients can reduce the clinical symptoms of DGP, enhance gastrointestinal motility, improve the gastric emptying rate, improve the quality of life, regulate the level of gastrointestinal hormones, and reduce the damage of autonomic nerve caused by oxidative stress, with good comprehensive clinical effect and safety in application.

ABSTRACT

OBJECTIVE@#To investigate the expression and clinical significance of serum protein ROCK2 in patients with chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).@*METHODS@#The patients were divided into cGVHD group and control group (without cGVHD). The expression levels of serum protein ROCK2 were detected by ELISA in patients with or without cGVHD after allo-HSCT.@*RESULTS@#The expression level of ROCK2 in serum of cGVHD patients was significantly higher than those in control group, moreover, the expression level of ROCK2 in severe cGVHD group was significant higher than that in moderate and mild cGVHD group (P<0.001). The expression level of ROCK2 was significantly decreased in the serum of cGVHD patients after treatment(P<0.01); the expression level of ROCK2 was significantly higher in the serum of cGVHD patients with lung as the target organ(P<0.01). The median survival time of patients with severe cGVHD were significantly shorter than that of patients with mild and moderate cGVHD(P<0.05).@*CONCLUSION@#ROCK2 shows certain reference value in the evaluation of severity and prognosis of cGVHD, and may be a new target for the treatment of cGVHD.

ABSTRACT

Objective:To explore the clinical characteristics, treatment and prognosis of myeloid sarcoma(MS).Methods:From January 2010 to May 2019, clinical data were reviewed for 89 MS cases. Age, gender, site of onset, type, comorbid diseases, lymphatic characteristics and disease remission status were analyzed. And 1-year survival rates were explored for different treatments including whether or not chemotherapy, transplantation and using hypomethylated drugs(HMAs)for maintenance after transplantation.Results:Among them, 21 cases had the data of chromosome karyotypic analysis and next generation sequencing and 8 patients underwent allogeneic hematopoietic stem cell transplantation(allo-HSCT). The 1-year overall survival rates(OS)of primary MS, MS with intramedullary disease and MS relapse after leukemic remission were 16.0%, 37.5% and 36.9% respectively( P=0.013). The 1-year OS of local treatment(surgical resection, intrathecal injection and local radiotherapy), chemotherapy plus local treatment and chemotherapy plus allo-HSCT was 0, 28.1% and 72.9% respectively( P=0.003). After two courses of treatment, the 1-year OS of patients with complete and incomplete remissions were 34.9% and 10.0% respectively( P=0.008). Half(4/8)MS patients relapsed within 1 year after transplantation and had a short survival.Three patients received decitabine after HSCT and all of them survived for a long time. Conclusions:Chemotherapy plus HSCT is efficacious for MS. Decitabine maintenance treatment after transplantation may prolong recurrence-free survival. However, a larger sample size is required for further clinical verifications.

ABSTRACT

Background/Aims@#Single-balloon enteroscopy (SBE) has been widely used in diagnosing small bowel disease. We conducted this study to systematically appraise its technical and clinical performance. @*Methods@#Studies on SBE published by September 2018 were systematically searched. Technical and clinical performance data were collected and analyzed with descriptive or meta-analysis methods. @*Results@#In total, 54 articles incorporating 4,592 patients (6,036 procedures) were included. Regarding technical parameters, the pooled insertion depths (IDs) for anterograde and retrograde SBE were 209.2 cm and 98.1 cm, respectively. The pooled retrograde ID in Asian countries was significantly greater than that in Western countries (129.0 cm vs 81.1 cm, p<0.001). The pooled anterograde and retrograde procedure times were 57.6 minutes and 65.1 minutes, respectively.The total enteroscopy rate was 21.9%, with no significant difference between Asian and Western countries. Clinically, the pooled diagnostic yield of SBE was 62.3%. Obscure gastrointestinal bleeding (OGIB) was the most common indication (50.0%), with a diagnostic yield of 59.5%. Vascular lesions were the most common findings in Western OGIB patients (76.9%) but not in Asian ones (31.0%). The rates of severe and mild adverse events were 0.5% and 2.5%, respectively. @*Conclusions@#SBE is technically efficient and is clinically effective and safe, but total enteroscopy is relatively difficult to achieve with this technique. Etiologies of OGIB in Asian countries differ from those in Western countries.

ABSTRACT

Rotational vertebral artery occlusion syndrome, also known as bow hunter′s syndrome (BHS), is a rare cause of posterior circulation ischemia. Digital subtraction angiography (DSA) is still the gold standard for diagnosis. A case of bilateral cerebellar infarction, with color Doppler ultrasound showing special vertebral artery hemodynamic changes after head and neck rotation, was diagnosed by DSA as BHS and intracranial vertebral artery dissection. Based on the literature published previously, the clinical manifestations and imaging features of BHS were discussed to improve clinicians′ awareness of the syndrome.

ABSTRACT

Objective:To compare the efficacy of the second generation tyrosine kinase inhibitor dasatinib combined with allogeneic hematopoietic stem cell transplantation(allo-HSCT)or chemotherapy in the treatment of Ph + acute lymphoblastic leukemia (Ph + ALL). Methods:A total of 56 Ph + ALL patients received dasatinib from January 2014 to June 2018. According to whether or not allo-HSCT was performed, they were divided into transplantation group(n=22)and chemotherapy group(n=34). The total survival rate(OS), disease-free survival rate(DFS), relapse and non-recurrence mortality(NRM)were compared between two groups. Results:The 2-year OS, DFS and cumulative recurrence rates were 69.1 % vs 47.8 %, 62.2 % vs 43.1 % and 14.6 % vs 44.1 % in transplantation and chemotherapy groups respectively. Significant inter-group differences existed in 2-year DFS, DFS and cumulative recurrence rates. The value of NRM was higher in transplantation group than that in chemotherapy group(18.6 % vs 14.1 %). However, the difference was statistically insignificant( P=0.476). Conclusions:The efficacy of dasatinib plus allo-HSCT is superior to that of dasatinib plus chemotherapy in the treatment of Ph + ALL.

ABSTRACT

Objective:To determine national trends for breast conserving surgery and to explore the factors affecting the scale of breast conserving surgery in China.Methods:A questionnaire survey was mailed to 110 hospitals with an year′s volume of more than 200 breast cancer surgeries in each center in China concerning hospital variations and percentage of breast conserving surgery.Results:The overall proportion of breast conserving surgery is 21.9% for operable breast cancer in China. There is a significant positive correlation between local Gross Domestic Product (GDP) and the rate of breast conserving surgery ( P=0.001). Hospitals with higher annual operation volume have higher breast-conserving ratios( P=0.042). Compared with non-teaching hospitals, more patients with stage I breast cancer underwent breast conserving surgery in teaching hospitals ( P=0.021). After breast-conserving surgery, the proportion of positive margins needing reoperation had a lower percentage and in cancer hospitals it was the lowest ( P=0.023). The method of pathological evaluation and the remedy strategy for positive margin was not related to per capita GDP and hospital category ( P>0.05). Conclusions:This survey demonstrates the current practices of breast conserving surgery in China. Local GDP, hospital category and tumor stage were factors influencing breast conserving surgery. Breast conserving surgery in China is still at a low level compared with developed countries.

ABSTRACT

Objective:To explore the imaging rate and diagnostic rate of positioning the fetal conus medullaris by three-dimensional ultrasound method to detect atlantoaxial intervertebral space, comparing it with the traditional two-dimensional and three-dimensional ultrasound methods.Methods:Consecutively 318 singleton fetuses received routine ultrasound screening during the second trimester were enrolled from November 2017 to December 2018 in Shenzhen Luohu People′s Hospital and Shenzhen People′s Hospital. These fetuses included 276 normal cases and 42 abnormal cases. The abnormal group contained 11 cases tethered cords fetuses(tethered cords group) and 31 cases non-tethered fetuses(non-tethered group). A new ultrasound method named detecting atlanto-axial intervertebral space with three-dimensional ultrasound and traditional two-dimensional and three-dimensional ultrasound methods were used to acquire and store the images. The positions of the fetal conus medullaris were analyzed blindly and recorded by three experienced physicians using three different methods with off-line software.Results:①The χ 2 test comparing multiple sample rates was used to compare the imaging acquisition success rate of fetal conus medullaris by three ultrasound methods. The test level was adjusted to be α′=0.05/4=0.0125, the results showed that there were no statistically significant differences between the three methods in the normal group (χ 2=7.39, P=0.025) and the abnormal group (χ 2=5.32, P=0.070). ②The χ 2 test comparing multiple sample rates was used to compare the diagnostic accuracy of fetal conus medullaris position in normal group by three methods, it showed there was no significant difference in the correct rate of conus medullaris position in the normal group (χ 2=2.52, P=0.284). ③The χ 2 test comparing multiple sample rates was used to compare the diagnostic accuracy of the fetal conus medullaris in tethered cord group and non-tethered group using 3 methods, the difference was not statistically significant in tethered cord group (χ 2=1.22, P=0.543), while the difference was statistically significant in non-tethered group(χ 2=9.69, P=0.008). Conclusions:The method of detecting atlanto-axial intervertebral space with three-dimensional ultrasound has a high imaging rate and diagnostic accuracy in positioning the fetal conus medullaris. Positioning of fetal conus medullaris by detecting atlanto-axial intervertebral space with three-dimensional ultrasound is better than traditional two-dimensional and three-dimensional ultrasound in the abnormal non-tethered fetuses, which can provide more valuable information for prenatal diagnosis consultation and prenatal and postnatal care.

ABSTRACT

Objective:To compare the efficacy of haploid hematopoietic stem cell transplantation (haplo-HSCT) and intensive immunosuppressive therapy (IST) in children with severe aplastic anemia (SAA).Methods:The medical records of children newly diagnosed as SAA in the First Affiliated Hospital of Zhengzhou University from January 2013 to June 2018 were retrospectively analyzed.Among them, 33 patients received haplo-HSCT and 24 patients received IST that combined anti-thymocyte globulin(ATG) with Cyclosporine (CsA). The effective rate, overall survival (OS) rate, and failure free survival(FFS) rate of children in the haplo-HSCT group and the IST group were compared.Results:The median follow-up period was 25 months (9-60 months). There were 5 cases of early death in the haplo-HSCT group and 4 cases in the IST group, and the differences were not statistically significant ( P=0.822). Leaving out the early death cases, the effective rate in the haplo-HSCT group [100%(28/28 cases)] was higher than that in the IST group [30%(6/20 cases)] after 3 months of treatment, the difference was statistically significant ( χ2=27.671, P<0.01). After 6 months of treatment, the effective rate in the haplo-HSCT group [92.9%(26/28 cases)] was higher than that in the IST group [65.0%(13/20 cases)], and the difference was statistically significant ( χ2=5.943, P=0.015). After 12 months of treatment, the effective rate in the haplo-HSCT group [89.3%(25/28 cases)] was higher than that in the IST group [70.0%(14/20 cases)], but the difference was not statistically significant( P>0.05). The 3-year expected OS rate of children in the haplo-HSCT group and the IST group were 75.0% and 70.3%, respectively, with no statistically significant difference ( χ2=0.133, P=0.716). The 3-year expected FFS rate of children in the haplo-HSCT group (74.2%) was significantly higher than that in the IST group (48.7%), and the difference was statistically significant ( χ2=4.036, P=0.045). Conclusion:For children with SAA, haplo-HSCT is also an effective treatment if there is no sibling donor of hematopoietic stem cell transplantation.

ABSTRACT

H7N9 avian influenza is a new subtype of avian influenza, first found in the Yangtze River Delta at the end of February 2013. H7N9 avian influenza, infection in human is transmitted through the respiratory airway, causing acute respiratory infectious disease. Due to the species barrier, H7N9 avian influenza virus only infect human via birds occasionally under very specific circumstances, and at present, there is no exact evidence of H7N9 avian influenza virus transmission between humans. However, H7N9 avian influenza remains a continuous public health threat. So far, China has had six outbreaks of H7N9 avian influenza. A total of 1567 cases of H7N9 influenza virus infection have been reported to WHO, including 615 deaths. When H7N9 avian influenza virus infects the human body, their primary target of infection is the respiratory mucosal epithelial cells. Therefore, the respiratory epithelium plays a key role in the process of virus transmission and infection. Hence, the main purpose of this review is to collate the current understanding of immune responses and their corresponding molecular mechanisms of mucosal damage caused by H7N9 avian influenza infection, and how it contributes to cross species human infection.

ABSTRACT

Polyphenol oxidase(PPO) is an important antioxidant enzyme in plants. It has the functions of scavenging active oxygen and synthesizing phenols, lignin, and plant protection factors, and can enhance the plant's resistance to stress and resistance to pests and diseases. Our previous research found that Salvia miltiorrhiza PPO gene can positively regulate salvianolic acid B synthesis. In order to further explore the mechanism, a pGBKT7-PPO bait vector was constructed using the cloned S. miltiorrhiza polyphenol oxidase gene(SmPPO, GenBank accession number: KF712274.1), and verified that it had no self-activation and no toxicity. The titer of S. miltiorrhiza cDNA library constructed by our laboratory was 4.75 × 107 cfu·mL~(-1), which met the requirements for library construction. Through yeast two-hybrid test, 22 proteins that could interact with SmPPO were screened. Only yeast PAL1 and TAT interacted with SmPPO through yeast co-transformation verification. Further verification was performed by bimolecular fluorescence complementary detection(BiFC). Only TAT and SmPPO interacted, so it meant that TAT and SmPPO interacted. TAT and SmPPO were truncated according to the domain, respectively. The first 126 amino acids of SmPPO and tyrosine amino transferase(TAT) were obtained to interact on the cell membrane and chloroplast. SmPPO was obtained by subcellular localization test, which was mainly loca-lized on the nucleus and cell membrane; TAT was localized on the cell membrane. Real-time quantitative PCR results showed that the SmPPO gene was mainly expressed in roots and stems; the TAT gene was expressed in roots, and the expression level in stems and flowers was low. This article lays a solid foundation for the in-depth study of the molecular mechanism of the interaction of S. miltiorrhiza SmPPO and TAT to regulate the synthesis of phenolic substances.

ABSTRACT

BACKGROUND@#Critical patients with the coronavirus disease 2019 (COVID-19), even those whose nucleic acid test results had turned negative and those receiving maximal medical support, have been noted to progress to irreversible fatal respiratory failure. Lung transplantation (LT) as the sole therapy for end-stage pulmonary fibrosis related to acute respiratory distress syndrome has been considered as the ultimate rescue therapy for these patients.@*METHODS@#From February 10 to March 10, 2020, three male patients were urgently assessed and listed for transplantation. After conducting a full ethical review and after obtaining assent from the family of the patients, we performed three LT procedures for COVID-19 patients with illness durations of more than one month and extremely high sequential organ failure assessment scores.@*RESULTS@#Two of the three recipients survived post-LT and started participating in a rehabilitation program. Pearls of the LT team collaboration and perioperative logistics were summarized and continually improved. The pathological results of the explanted lungs were concordant with the critical clinical manifestation, and provided insight towards better understanding of the disease. Government health affair systems, virology detection tools, and modern communication technology all play key roles towards the survival of the patients and their rehabilitation.@*CONCLUSIONS@#LT can be performed in end-stage patients with respiratory failure due to COVID-19-related pulmonary fibrosis. If confirmed positive-turned-negative virology status without organ dysfunction that could contraindicate LT, LT provided the final option for these patients to avoid certain death, with proper protection of transplant surgeons and medical staffs. By ensuring instant seamless care for both patients and medical teams, the goal of reducing the mortality rate and salvaging the lives of patients with COVID-19 can be attained.

ABSTRACT

BACKGROUND@#Increased right ventricle afterload during acute respiratory distress syndrome (ARDS) may induce acute cor pulmonale (ACP), which is associated with a poor clinical outcome. Echocardiography is now considered as a rapid and non-invasive tool for diagnosis of ACP. The aims of this study were to investigate the morbidity and mortality rates of ACP in ARDS patients in intensive care units (ICUs) across the mainland of China and to determine the severity and prognosis of ACP in ARDS patients through an ultrasound protocol (TRIP). And the association between ACP related factors and the ICU mortality will be revealed.@*METHODS@#This study is a multicenter and cross-sectional study in China which will include ICU participants when diagnosed as ARDS. The ultrasound protocol, known as the TRIP, is proposed as severity assessment for ACP, which includes tricuspid regurgitation velocity (T), right ventricular size (R), inferior vena cava diameter fluctuation (I), and pulmonary regurgitation velocity (P). The 28-day mortality, ICU/hospital mortality, the length of stay in ICU, mechanical ventilation days, hemodynamic parameters and lab parameters of liver function and kidney function are all recorded.@*DISCUSSION@#This large-scale study would give a sufficient epidemic investigation of ACP in ARDS patients in China. In addition, with the TRIP protocol, we expect that we could stratify ACP with more echocardiography parameters.@*TRIAL REGISTRATION@#NCT03827863, https://clinicaltrials.gov/ct2/show/NCT03827863.

ABSTRACT

Immunotherapy has become a highly promising paradigm for cancer treatment. Herein, a chemo-immunotherapy was developed by encapsulating chemotherapeutic drug doxorubicin (DOX) and Toll-like receptor 7 agonist imiquimod (IMQ) in low molecular weight heparin (LMWH)-d--tocopheryl succinate (TOS) micelles (LT). In this process, LMWH and TOS were conjugated by ester bond and they were not only served as the hydrophilic and hydrophobic segments of the carrier, but also exhibited strong anti-metastasis effect. The direct killing of tumor cells mediated by DOX-loaded micelles (LT-DOX) generated tumor-associated antigens, initiating tumor-specific immune responses in combination with IMQ-loaded micelles (LT-IMQ). Furthermore, the blockade of immune checkpoint with programmed cell death ligand 1 (PD-L1) antibody further elevated the immune responses by up-regulating the maturation of DCs as well as the ratios of CD8 CTLs/T and CD4 T/T. Therefore, such a multifunctional strategy exhibited great potential for inhibiting the growth of orthotopic and metastatic breast cancer.
