ABSTRACT

Patient diagnosis and treatment data are scattered in various clinical systems related to electronic medical records(EMR). The data can be better applied to the emergency prevention and control, medical research and government supervision only through unified integration. The authors analyzed the construction level of the EMR system in medical institutions, and sorted out the problems faced by directly extracting the diagnosis and treatment data of patients through the EMR system, including the lack of patient-centered integration of data, insufficient application depth of the EMR system, insufficient data standardization, lack of data and so on. Public health emergencies posed a severe challenge to the extraction of EMR data.For medical institutions with different information construction levels, the authors gave a feasibility analysis of data extraction by classification and time period, and suggested that medical institutions should fundamentally strengthen the understanding of information, establish data standard system and realize data integration and unified management.

ABSTRACT

Objective:This study aims to analyze the counts (per kilogram of body weight) or percentages of transplanted lymphocyte subgroups in children with non-infectious pulmonary complications (NIPC) and air-leak syndrome (ALS) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and explore its significance in the progression of lung complications after transplantation.Methods:The patients with NIPC and ALS after allo-HSCT from January 2013 to December 2019 in Hebei Yanda Ludaopei Hospital were retrospectively studied and the influencing factors in the progress of NIPC after HSCT were statistically analyzed.Results:Of the 2026 children who received HSCT treatment, 59 patients (34 males and 25 females) developed NIPC, the probability was 2.9% (59/2 026), and the probability of combined ALS was 1.4% (28/206). The differences in the comparison between NIPC progressed to ALS group (ALS group) and failed to progress to ALS group (non-ALS group) in the patient′s age( P=0.028), disease condition before transplantation( P=0.022), NIPC onset time( P=0.004) were significant. The P values of the percentage of NKT-like cells in the bone marrow ( P=0.008) or peripheral stem cells ( P=0.003) accounted for the lymphocytes. CD4+CD25+dim cells in bone marrow ( P=0.029) or peripheral stem cells ( P=0.036) accounted for the CD4+lymphocytes and the ratio of CD4/CD8 in bone marrow( P=0.004) or peripheral stem cells ( P=0.020) were less than 0.05, which meant the differences in patients′ refusion cells were significant. In the binary logistic regression model, the percentage of bone marrow NKT-like cells to lymphocytes, the ratio of bone marrow CD4+/CD8+and the percentage of peripheral stem NK cells to lymphocytes were important risk factors for the progression of NIPC to ALS. The rest factors were excluded from the model (AUC=0.918, P<0.05). Conclusion:During allo-HSCT transplantation, a high proportion of NKT-like cell and NK cell levels, and a high CD4+/CD8+ratio in the infusion of donors with high immune tolerance have an important correlation with the progression of the NIPC.

ABSTRACT

Objective:To observe the efficacy and safety of the combination of agomelatine and low-dose olanzapine (AO) in the treatment of postprandial distress syndrome (PDS) with depression, anxiety and sleep disorders.Methods:From April 2019 to September 2020, PDS patients with depression, anxiety and sleep disorders in Tianjin Medical University General Hospital were selected and divided into AO group and flupentixol-melitracen (FM) group. Patients of the AO group were given oral agomelatine 25 mg and AO 1.70 mg (both once per day), and the patients of FM group were given oral FM 10.5 mg (once per day), and all patients took itopride 50 mg (three times per day) at the same time. The total treatment course was eight weeks. Nepean dyspepsia index-symptom (NDIS), patient health questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7) and Pittsburgh sleep quality index (PSQI) were used to evaluate the gastrointestinal symptoms, depression, anxiety and sleep disorders before treatment and two, four and eight weeks after treatment, respectively. The efficacy was evaluated according to the changes of scores of gastrointestinal symptoms before and after treatment. The adverse effects after medication were recorded. Independent sample t test and chi-square test were used for statistical analysis. Results:A total of 184 PDS patients with depression, anxiety and sleep disorders were enrolled, including 98 patients in AO group and 86 patients in FM group. At two, four and eight weeks after treatment, NDIS, PHQ-9, GAD-7 and PSQI scores of AO group and FM group were all lower than those of each group before treatment (AO group: 13.73±0.53, 10.13±0.44 and 7.87±0.31 vs. 27.08±0.84; 6.04±0.35, 4.70±0.31 and 3.81±0.22 vs. 10.04±0.50; 6.36±0.30, 5.29±0.28 and 4.21±0.19 vs. 10.71±0.51; 6.64±0.37, 5.27±0.35 and 4.09±0.30 vs. 11.14±0.42; FM group: 15.33±0.58, 11.58±0.50 and 9.80±0.35 vs. 25.10±0.79; 6.79±0.35, 5.71±0.32 and 4.86±0.30 vs. 9.11±0.46; 7.27±0.31, 6.51±0.32 and 5.21±0.27 vs. 9.79±0.44; 8.01±0.33, 6.76±0.32 and 5.78±0.32 vs. 10.44±0.32), and the differences were statistically significant (AO group: tNDIS=13.470, 17.930 and 21.530, tPHQ-9=6.488, 8.991 and 11.300, tGAD-7=7.361, 9.315 and 11.031, tPSQI=7.088, 9.736 and 12.550. FM group: tNDIS=9.921, 14.400 and 17.640, tPHQ-9=4.032, 6.106 and 7.781, tGAD-7=4.638, 5.993 and 8.840, tPSQI=5.289, 8.199 and 10.310, all P<0.05). At two, four and eight weeks after treatment, NDIS, GAD-7 and PSQI scores of AO group were all lower than those of the FM group during the same period (NDIS: 13.73±0.53 vs. 15.33±0.58, 10.13±0.44 vs. 11.58±0.50, 7.87±0.31 vs. 9.80±0.35; GAD-7: 6.36±0.30 vs. 7.27±0.31, 5.29±0.28 vs. 6.51±0.32, 4.21±0.19 vs. 5.21±0.27; PSQI: 6.64±0.37 vs. 8.01±0.33, 5.27±0.35 vs. 6.76±0.32, 4.09±0.30 vs. 5.78±0.32), and the differences were statistically significant ( tNDIS=2.018, 2.225 and 4.156, tGAD-7=2.097, 2.869 and 2.536, tPSQI=1.951, 2.359 and 3.099, all P<0.05).

ABSTRACT

Objective:To investigate the acute effect of fructose intake on serum uric acid, plasma glucose, and insulin levels in healthy young adults.Methods:Sixty-four healthy young subjects were recruited, and randomized to 25 g, 50 g, 75 g fructose group, and 75 g glucose group( n=16) by random number table. The anthropometric parameters, blood pressure, heart rate were measured. Several biochemistry parameters were measured, which were serum uric acid, plasma glucose, plasma insulin, serum total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C) at 0, 60, 120, and 180 min before and after ingestion of fructose or glucose. Results:(1) The serum uric acid level after fructose administration increased significantly than after glucose over 3 h, and peaked at 60 min. The increment of uric acid at 60 min and area under curve of uric acid at 3 h after fructose administration were significantly higher than those of glucose. The increment of uric acid at 60 min increased significantly as fructose dose was increased, especially in the 75 g fructose (increment rate of uric acid at 60 min in 25g, 50g, 75g fructose groups were 9.33%, 13.11%, 17.69% vs 0.75% respectively; Areas under curve of uric acid were 1 674.1±410.38, 1 598.3±417.03, 1 504.6±292.46 vs 1 434.8±328.94, P<0.01). (2) The glucose and insulin levels increased after fructose/glucose intake in four groups with top augment in glucose followed by 75 g fructose. The increase peaked at 30 min, began to decline at 120 min, and returned to fasting level at 180 min. The area under curve of insulin at glucose group was significantly higher than those among fructose groups. With the increase of fructose dose, the increment rate of glucose and insulin at 60 min also increased obviously, especially in the 75 g fructose (the increment rates of glucose at 60 min in 25 g, 50 g, 75 g fructose, 75 g glucose were 7.40%, 8.29%, 13.74%, 28.22% respectively; The increment rates of insulin at 60 min were 54.29%, 115.25%, 185.58%, 730.31% respectively, P<0.01). (3) There were no difference of cholesterol, triglyceride, and LDL-C after fructose/glucose ingestion. Conclusion:Acute fructose intake can lead to the increase of uric acid and insulin; Moreover, the increments of uric acid and insulin after fructose consumption were dependent on fructose dose.

ABSTRACT

Objective:To evaluate the effect of paravertebral nerve block (PVNB) combined with general anesthesia on intraoperative regional cerebral oxygen saturation (rScO 2) in elderly patients undergoing thoracoscopic lobectomy. Methods:Seventy American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients of both sexes, aged 60-85 yr, with body mass index of 18-25 kg/m 2, were divided into 2 groups ( n=35 each) using a random number table method: general anesthesia group (group G) and PVNB combined with general anesthesia group (group PG). PVNB was performed at T 4 and T 6 with 0.5% ropivocaine 10 ml for each site under ultrasound guidance before induction of anesthesia in group PG.After induction of anesthesia, anesthesia was maintained with IV propofol and remifentanil, and a patient-controlled intravenous analgesia pump was connected at the end of operation.The maximum and minimum rScO 2 and cumulative time of rScO 2 below the baseline value were recorded.The rScO 2 was recorded before anesthesia (T 0), at 5 min before one-lung ventilation (T 1), at 5 min after one-lung ventilation (T 2) and at tracheal extubation (T 3). The length of postoperative hospital stay and complications within 30 days after operation were recorded. Results:Compared with group G, the minimum rScO 2 and rScO 2 at T 2 and T 3 were significantly increased, the incidence of postoperative cognitive dysfunction was reduced ( P<0.05), and no significant change was found in the other parameters mentioned above in group PG ( P>0.05). Conclusion:PVNB combined with general anesthesia can improve intraoperative rScO 2 and reduce the development of postoperative cognitive dysfunction in elderly patients undergoing thoracoscopic lobectomy.

ABSTRACT

Objective:To investigate the correlation between early renal impairment markers in urine and elevated serum homocysteine.Methods:Clinical data of serum homocysteine (Hcy) and early renal injury markers in urine of the health examination population from the Physical Examination Center of Peking University Third Hospital from January 2019 to May 2020 were retrospectively analyzed (1133 cases). The previous medical history, age, sex, blood pressure, body mass index (BMI) of the subjects were collected. Early urine kidney injury markers, including urine microalbumin (U-mALB), urinary N-acetyl-β-D-glucosaminidase (NAG), urinary albumin to creatinine ratio (UACR), and serum renal function, liver function, blood lipid, myocardial enzyme and glycosylated hemoglobin (HbA 1C), etc. were also collected. Those with incomplete previous history, general information, biochemical indexes and decreased estimated glomerular filtration rate (eGFR) were excluded, and 969 cases were included. The included subjects were divided into the normal group (?15 μmol/L) and the elevated group (≥15 μmol/L) according to Hcy levels, the indexes with significant difference between the two groups were included as independent variables, and the multivariate logistic regression was used to explore the influence factors of Hcy elevation. Results:The male ratio, the incidence of increased U-mALB, NAG and UACR were significantly higher in the elevated group than those in the normal Hcy group (93.4% vs 50.6%, 16.4% vs 8.0%, 23.0% vs 14.0%, 13.9% vs 7.9%) (all P<0.05). Systolic blood pressure, diastolic blood pressure, serum uric acid, calcium, alanine aminotransferase (ALT) and lactate dehydrogenase in the elevated group were higher than those in the normal group [(127.5±15.4) vs (121.9±16.2) mmHg (1 mmHg=0.133 kPa), (78.6±9.3) vs (76.0±11.0) mmHg, (385.9±86.0) vs (335.7±88.2) μmol/L, (2.392±0.086) vs (2.366±0.092) mmol/L, (27.8±21.0) vs (23.8±20.2) U/L, (198.3±28.4) vs (192.2±31.2) U/L] (all P<0.05), while high density lipoprotein cholesterol (HDL-C), serum phosphorus were lower than those in the normal group [(1.21±0.25) vs (1.31±0.30) mmol/L, (1.107±0.154) vs (1.158±0.159) mmol/L] (all P<0.05). The increased systolic blood pressure, male, uric acid, U-mALB, NAG were independent correlative factors of Hcy elevation. Conclusion:The increase of Hcy is independently correlated with urine U-mALB and NAG, which suggests that the level of Hcy should be detected as soon as possible in patients with elevated early renal injury markers.

ABSTRACT

Objective:To analyze the clinical features of adult patients with extremely elevated erythrocyte sedimentation rate (ESR, ESR≥100 mm/1 h), so as improve the ability of clinicians to use erythrocyte sedimentation rate to assist in the diagnosis and treatment of diseases.Methods:A retrospective cohort study was conducted to examine the clinical data of patients with ESR ≥ 100 mm/1 h admitted to the First Affiliated Hospital of Kunming Medical University from January 1st 2019 to December 31st 2019. The age, gender, clinical diagnosis, first ESR level after admission, blood routine, liver function, renal function, coagulation function and C-reactive protein (CRP) within 24 hours after admission were collected. Patient cohorts were divided into youth group (18-65 years old), middle-aged group (66-79 years old) and elderly group (≥80 years old) according to the new standards of human age classification of World Health Organization (WHO) 2019. Patient cohorts were also divided into infectious disease group, hematological disease group, autoimmune disease group, renal failure group and others according to their respective clinical diagnosis. The distribution of extremely elevated ESR in each group, and the correlation between ESR and various laboratory indicators were analyzed.Results:① Among 429 patients with ESR≥ 100 mm/1 h, there were 236 males and 193 females. There was no significant difference in ESR levels between males and females [mm/1 h: 108.00 (103.00, 119.75) vs. 117.00 (105.50, 140.00), P = 0.234]. ② The age of 429 patients ranged from 18 to 98 years old, the average age was (53.70±18.70) years old. There were 310 cases in the youth group, 87 cases in the middle-aged group and 32 cases in the elderly group. The ESR level of the young group was significantly lower than that of the middle-aged group and the elderly group [mm/1 h: 108.00 (103.00, 120.00) vs. 119.00 (107.00, 140.00), 120.00 (110.25, 140.00), both P < 0.01]. ③ The main diagnoses associated with extremely elevated ESR were infectious diseases [157 cases (36.6%)], hematological system diseases [127 cases (29.6%)], autoimmune diseases [74 cases (17.2%)]. Pulmonary infection accounted for 58.0% (91/157) of infectious diseases. Hematopoietic stem cell diseases accounted for 45.7% (58/127), lymphocyte and plasma cell diseases accounted for [37.0% (47/127)] and erythrocyte diseases accounted for [11.0% (14/127)] of the hematological system diseases. Diffuse connective tissue diseases accounted for 75.7% (56/74) of autoimmune diseases. ④ Spearman correlation analysis showed that the extremely elevated ESR in all patients was significantly negatively correlated with the levels of red blood cell count (RBC), hemoglobin (HB) and hematocrit (HCT) (ρvalue was -0.395, -0.381 and -0.383, respectively, all P < 0.01), the ESR was significantly positively correlated with the level of fibrinogen (FIB; ρ= 0.345, P < 0.01). A total of 266 patients were tested for both ESR and CRP, and there was no significantly correlation between ESR and CRP level (ρ= -0.019, P = 0.756). Conclusions:The extremely elevated ESR was more common in pulmonary infections diseases, hematopoietic stem cell diseases, lymphocyte and plasma cell diseases, erythrocyte diseases and diffuse connective tissue diseases. The extremely elevated ESR was significantly correlated with the levels of RBC, HB, HCT and FIB.

ABSTRACT

ObjectiveTo investigate the three-year follow-up outcomes of hepatocellular carcinoma patients undergoing liver resection (LR) versus liver transplantation (LT). MethodsA retrospective analysis was performed for 171 patients with hepatocellular carcinoma who underwent surgical treatment in Beijing YouAn Hospital, Capital Medical University, from March 2009 to March 2014, and according to the treatment method, they were divided into LR group(n=83) and LT group(n=88). Related clinical data were compared between the two groups. The chi-square test was used for comparison of categorical data between two groups; the Kaplan-Meier survival curve and the log-rank test were used for comparison of disease-free survival and overall survival between two groups, and the Cox proportional hazards model was used for the univariate and multivariate analyses of disease-free survival and overall survival. ResultsCompared with the LR group, the LT group had a significantly higher proportion of patients with single tumor [45.78% (38/83) vs 85.23% (75/88), χ2=29649,P<0.001], tumor size <3 cm [15.66% (13/83) vs 6705% (59/88), χ2=46.383,P<0001], or high Child-Pugh class [ 964% (8/83) vs 26.14% (23/88),χ2=7833,P=0.005] and a significantly lower recurrence rate of tumor [48.19%(40/83) vs 3295%(29/88) ,χ2=4121,P=0.042]. There was a significant difference in disease-free survival rate between the LR group and the LT group (46.02% vs 80.71%, P=0.006); the LT group had a higher overall survival rate than the LR group (86.99% vs 76.44%, P=0.219). Both univariate and multivariate analyses showed that treatment method was an independent risk factor for disease-free survival (risk ratio[RR]=3383,95% confidence interval[CI]: 1334-8579;RR=0239,95%CI:0093-0.612,both P<005), but the prediction of overall survival by treatment method did not reach statistical significance(P=0232). ConclusionLT is recommended for patients with early-stage hepatocellular carcinoma and can achieve a satisfactory three-year disease-free survival rate.

ABSTRACT

Podophyllotoxin (PTOX) is an aryl-tetralin lignan of plant origin found in some species of Podophyllum such as Dysosma versipellis, Diphylleia sinensis, and Sinopodophyllum hexandrum. Etoposide and teniposide are produced semisynthetically from PTOX and used clinically to treat several forms of cancer. As a typical representative of new drug discovery from natural products, the production of PTOX solely depends on extraction from plants, resulting in severe contradiction between supply and demand. With the advantages of unconstrained resources and eco-friendly reaction conditions, biosynthesis method has become a trend in the production of PTOX and its derivatives. In this review, we summarize the research progress of PTOX biosynthesis in plants and expound the functions of the key enzymes as well as their subcellular location. The synthetic biology for production of PTOX intermediates in a tobacco chassis is also introduced. Finally, the heterologous expression and biotransformation of PTOX in microorganisms is summarized, which sets the foundation for the efficient microbial production of PTOX using cell factories.

ABSTRACT

Objectives:To analyze the prevalence and risk factors of chronic nephropathy among hospitalized gout patients.Methods:537 hospitalized gout patients in Tianjin Medical University Chu Hsien-I Memorial Hospital were enrolled. According to the levels of glomerular filtration rate (eGFR>90 ml/min, 60-90 ml/min and <60 ml/min), patients were divided into normal group, mild chronic nephropathy group and moderate-severe chronic nephropathy group. The height, weight, waist, hip and blood pressure of the patients were measured. Blood samples from elbow vein were collected to measure biochemical indexes. The 24-hour urine was collected to measure creatinine and uric acid. Multivariate regression analysis was used to analyze the related factors that may affect eGFR.Results:The prevalence of chronic nephropathy among gout patients was 46.76%(251/537), which the prevalence of mild chronic nephropathy was 34.82%(187/537), and moderate severe chronic nephropathy was 11.92%(64/537). With the decline of eGFR, the older the patients, the longer the course of gout and hypertension, the more the number of joints involved, the higher the blood uric acid, urinary microalbumin, urinary protein, white blood cell count, uric acid excretion fraction (FeUA), and the lower the red blood cell count, hemoglobin and serum albumin. Pearson correlation analysis of eGFR showed that age, duration of gout and hypertension, number of involved joints, hemoglobin, serum albumin, serum uric acid, urinary microalbumin, and FeUA were correlated with eGFR ( r=-0.43, -0.238, -0.25, -0.128, 0.155, 0.138, -0.169, -0.29, -0.372, respectively, P<0.01). Multivariate regression analysis showed that age, the course of gout, serum uric acid, microalbuminuria and FeUA were independent risk factors for eGFR decline ( P<0.01). Conclusions:Eldly, long course of gout, poor control of serum uric acid and increased excretion of uric acid and microalbumin are risk factors of gout.

ABSTRACT

Objective:To understand the Penn Acoustic Neuroma Quality of Life (PANQOL) Scale, and to promote the consistency of Chinese-English scale language expression.Methods:By objective sampling method, 30 patients who met the inclusion criteria were used as the subjects to conduct one-to-one cognitive interviews to explore the understanding of the contents of the PANQOL scale. The consistency of the items of the scale and its response scale, as well as the possible problems of the scale. According to the interview results, the Chinese version of the PANQOL scale was established by optimizing the items, expressions and words used.Results:Two rounds of cognitive interviews were conducted in this study. The results of the first round showed that the items of the scale were not set properly and the 8 items appeared "understanding difference, non-verbal expression" and so on. The second round of interviews showed that the revised scale items were more similar to the original scale.Conclusions:Cognitive interview is helpful for researchers to find out the problems of the Chinese version PANQOL scale in the process of filling out the target population, and to guide the group to revise the items in doubt, so that the language of the scale after cultural adjustment is easy to understand, the expression is more local, and finally the quality of the scale is improved.

ABSTRACT

Objective:To explore the effect of probiotics on reducing ventilator-associated pneumonia (VAP) in sepsis patients.Methods:A total of 94 cases were randomly (random number) divided into the probiotic group ( n = 46) and the control group ( n = 48). All of the patients were given enteral nutrition therapy by nasogastric tube within 24-72 h after admission. And patients in the probiotic group were given live combined bifidobacterium, lactobacillus and enterococcus powder besides the regular therapy. The incidence of VAP, bacteremia, mortality, mechanical ventilation time and length of ICU stay were compared between the two groups. Results:Compared with the control group, the incidences of VAP and bacteremia in the probiotics group were significantly lower (χ 2=4.763, P=0.029; χ 2=4.438, P=0.035). There were no significant differences in 28-day mortality and the length of hospital stay between the two groups (χ 2=2.02, P=0.167; t=1.29, P=0.208). Mechanical ventilation time in the probiotics group was significantly shorter than that in the control group ( t=2.16, P=0.038). The Log-Rank test showed that the time of VAP-free in the probiotics group was significantly longer than that in the control group ( P < 0.05). After adjusting for APACHEⅡ score and age, COX proportional risk model analysis showed that the RR values of the probiotics group and the control group for 28-day VAP were 0.18 (95% CI: 0.12-0.74, P=0.025) and 0.21 (95% CI: 0.19-0.95, P=0.042), respectively. Conclusions:Probiotics treatment can reduce the incidence of VAP in sepsis patients.

Objective:To explore the clinical application of NanoString fluorescent barcode technology in the molecular subtyping of diffuse large B-cell lymphoma (DLBCL), and to analyze the correlation between the cell-of-origin subtype and prognosis of patients.Methods:The tumor tissue samples of 12 patients with DLBCL at the Third People's Hospital of Datong of Shanxi Province and 8 patients with DLBCL at Peking University, Health Science Center between January 2014 and December 2019 were collected. According to Hans algorithm, all patients were divided into 1 case of germinal center-derived B-cell (GCB) type and 19 cases of non-GCB type. NanoString platform was used to analyze the expression level differences of 15 genes-related to Lymph2Cx molecular subtyping of all samples at mRNA level. Hierarchical clustering was used to subgroup 20 DLBCL cases and to contrast the prognosis in different subgroups according to the subtyping.Results:NanoString fluorescent barcode technology was used to detect samples of 20 DLBCL cases and hierarchical clustering analysis was performed, and then subtyping results showed that 11 cases were GCB-like type and 9 cases were activated B cell (ABC)-like type. Based on Hans algorithm, 10 GCB-like cases were non-GCB type. According to the survival analysis, GCB-like group had a better overall survival compared with that in ABC-like group ( P=0.019). Conclusion:NanoString fluorescent barcode technology can be successfully applied to the cell-of-origin subtyping of DLBCL, and the molecular subtyping strategy can effectively predict the prognosis of patients.

ABSTRACT

Tumor microenvironment has been widely utilized for advanced drug delivery in recent years, among which hypoxia-responsive drug delivery systems have become the research hotspot. Although hypoxia-responsive micelles or polymersomes have been successfully developed, a type of hypoxia-degradable nanogel has rarely been reported and the advantages of hypoxia-degradable nanogel over other kinds of degradable nanogels in tumor drug delivery remain unclear. Herein, we reported the synthesis of a novel hypoxia-responsive crosslinker and the fabrication of a hypoxia-degradable zwitterionic poly(phosphorylcholine)-based (

ABSTRACT

OBJECTIVE@#Using network pharmacology to explore the mechanism of the 'invigorating qi and promoting blood circulation' drug pair Ginseng-Danshen (Salvia miltiorrhiza) on treatment of ischemic heart disease (IHD).@*METHODS@#The chemical constituents of ginseng and Danshen drug pair were identified by searching the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and the potential targets of the pair were identified. The pharmacodynamics of the pair was analyzed using network pharmacology. The targets of IHD were identified by database screening. Using protein-protein interaction network, the interaction targets of Ginseng-Danshen on IHD were constructed. A "constituent-target-disease" interaction network was constructed using Cytoscape software, Gene Ontology (GO) term enrichment analysis and biological pathway enrichment analysis were carried out, and the mechanism of improving myocardial ischemia by the Ginseng-Danshen drug pair was investigated.@*RESULTS@#Seventeen active constituents and 53 targets were identified from ginseng, 53 active constituents and 61 targets were identified from Danshen, and 32 protein targets were shared by ginseng and Danshen. Twenty GO terms were analyzed, including cytokine receptor binding, cytokine activity, heme binding, and antioxidant activity. Sixty Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathways were analyzed, including phosphatidylinositol 3-kinase-serine-threonine kinase (PI3K-AKT) signaling pathway, p53 signaling pathway, interleukin 17 signaling pathway, tumor necrosis factor signaling pathway, and the advanced glycation end product (AGE)-the receptor for AGE (RAGE) signaling pathway in diabetic complications.@*CONCLUSION@#The specific mechanism of Ginseng-Danshen drug pair in treating IHD may be associated with improving the changes of metabolites inbody, inhibiting the production of peroxides, removing the endogenous oxygen free radicals, regulating the expression of inflammatory factors, reducing myocardial cell apoptosis and promoting vascular regeneration.

ABSTRACT

OBJECTIVE@#To investigate the clinical characteristics and treatment outcome of patients with Burkitt lymphoma.@*METHODS@#The clinical data of 27 patients with Burkitt Lymphoma were collected and retrospectively analyzed, the clinical characteristics, laboratory data, survival and the factors affecting the prognosis were also analyzed.@*RESULTS@#Among the 27 patients (mainly for adults), the median age was 30 (15-83) years old, the ratio of male and female was 3.5∶1. There was no EB virus infection in all the patients, 92.6% of the patients showed extranodal organs involvement, 40.7% of them were leukemic stage, 85.2% patients belonged to Ⅲ and Ⅳ stage, 74.1% patients belonged to high/high-middle risk according to IPI index. In the terms of molecular biology, five patients were treated with next-generation sequencing test, and the MYC gene mutations were detected out in alt the patients, and the most common mutations were CCND3, ID3 and TP53. The overall response rate (ORR) for all the patients was 85.2%, the complete response (CR) rate was 63.0%, and the partial response rate was 22.2%, the 5-year progression-free survival rate and overall survival rate of the patients was 76.6% and 76.6%, respectively, which showed that the efficacy of the patients in high-dose methotrexate treatment group was higher than that in the non-high high-dose methotrexate treatment group. For the patients treated with LMB89 chemotherapy, the CR was 78.6%, ORR was 100%, the 5-year survival rate was 92.9%, which was superior to the patients treated with other regimens. Auto-hematopoietic stem cell transplantation as consolidation treatment could improve the prognosis for those patients who could not tolerate high-dose chemotherapy. Univariate analysis showed that ECOG score, the level of LDH>500 U/L, WBC level, CNS involvement, short-term effect and LMB89 regimen were the risk factors affecting the prognosis of the patients.@*CONCLUSION@#The adult Burkitt lymphoma are highly aggressive. For the patients in high-dose methotrexate treatment group, especially LMB89 regimen can improve the survival of the patients, and to choose HSCT as a consolidation treatment can be a choice for those patients who could not tolerate high-dose chemotherapy.

ABSTRACT

Type 2 diabetes mellitus( T2 DM) is a common chronic metabolic disease characterized by persistent hyperglycemia and insulin resistance. In pancreatic β-cells,glucose-stimulated insulin secretion( GSIS) plays a pivotal role in maintaining the balance of blood glucose level. Previous studies have shown that geniposide,one of the active components of Gardenia jasminoides,could quickly regulate the absorption and metabolism of glucose,and affect glucose-stimulated insulin secretion in pancreatic β cells,but the specific mechanism needs to be further explored. Emerging evidence indicated that glycosylation of glucose transporter( GLUT) has played a key role in sensing cell microenvironmental changes and regulating glucose homeostasis in eucaryotic cells. In this study,we studied the effects of geniposide on the key molecules of GLUT2 glycosylation in pancreatic β cells. The results showed that geniposide could significantly up-regulate the mRNA and protein levels of Glc NAc T-Ⅳa glycosyltransferase( Gn T-Ⅳa) and galectin-9 but had no signi-ficant effect on the expression of clathrin,and geniposide could distinctively regulate the protein level of Gn T-Ⅳa in a short time( 1 h) under the conditions of low and medium glucose concentrations,but had no significant effect on the protein level of galectin-9. In addition,geniposide could also remarkably affect the protein level of glycosylated GLUT2 in a short-time treatment. The above results suggested that geniposide could quickly regulate the protein level of Gn T-Ⅳa,a key molecule of protein glycosylation in INS-1 rat pancreatic βcells and affect the glycosylation of GLUT2. These findings suggested that the regulation of geniposide on glucose absorption,metabolism and glucose-stimulated insulin secretion might be associated with its efficacy in regulating GLUT2 glycosylation and affecting its distribution on the cell membrane and cytoplasm in pancreatic β cells.

ABSTRACT

Objective:To observe the changes of skeletal muscle indexes in elderly patients with type 2 diabetes complicated with sarcopenia treated with sitagliptin and acarbose.Methods:A total of 60 patients over 60 years old with type 2 diabetes complicated with sarcopenia in Dalian Municipal Central Hospital from January 2019 to January 2020 were selected and divided into two groups by random number table method.One group received sitagliptin and metformin,and the other group received acarbose and metformin. The changes of skeletal muscle indexes, glucagon-like peptides-1 (GLP-1), insulin resistance index (HOMA-IR) and inflammatory indexes were compared between the two groups at baseline and 36 weeks after treatment.Results:After treatment, the skeletal muscle index (SMI) of sitagliptin group was increased (5.94 ± 1.52 vs. 5.99 ± 1.52), and the difference was statistically significant ( P<0.05). Muscle strength and SMI decreased in acarbosse group (18.75 ± 4.64 vs. 17.72 ± 4.44, 6.09 ± 1.74 vs. 6.00 ± 1.71), with statistical significance ( P<0.05). GLP-1 increased in sitagliptin group, 0 min: (10.65 ± 1.68) pmol/L vs. (12.41 ± 1.88) pmol/L; 60 min: (22.79 ± 2.85) pmol/L vs. (25.51 ± 2.79) pmol/L; 120 min: (24.26 ± 2.94) pmol/L vs. (29.49 ± 2.91) pmol/L; 180 min: (11.68 ± 1.84) pmol/L vs. (12.88 ± 1.83) pmol/L. There were significant differences ( P<0.05). HOMA-IR and CRP decreased: 4.73 ± 3.04 vs. 3.16 ± 2.41, (2.39 ± 0.50) mg/L vs. (2.33 ± 0.43) mg/L, and the differences were statistically significant ( P<0.05). HOMA-IR in acarbose group decreased after treatment (5.80 ± 3.94 vs. 4.00 ± 1.63), and the difference was statistically significant ( P<0.05). Comparison between the two groups after treatment, the decreased value of muscle strength in sitagliptin group was less than that in acarbose group, and the difference was statistically significant ( P<0.05). GLP-1 and overall GLP-1 area under the curve in sitagliptin group were higher than those in acarbose group (67.64 ± 6.81 vs. 58.98 ± 6.72), with statistical significance ( P<0.05). HOMA-IR and CRP in sitagliptin group were lower than those in acarborose group: 3.16 ± 2.42 vs. 4.00 ± 1.63, (2.33 ± 0.43) mg/L vs. (2.41 ± 0.70) mg/L, with statistical significances ( P<0.05). Conclusions:Sitagliptin therapy improves muscle mass and protects muscle strength in elderly patients with type 2 diabetes mellitus and sarcopenia.

ABSTRACT

Objective:To investigate and compare the changes of modulation transfer function (MTF) after small-incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK).Methods:A cohort study was conducted.One hundred and two myopic patients (102 eyes) who underwent SMILE and FS-LASIK in Tianjin Eye Hospital from December 2015 to June 2016 were enrolled and divided into SMILE group with 53 eyes and FS-LASIK group with 49 eyes according to different surgical methods.The ocular aberrations and corneal morphology of all patients were measured by the Hartman-Shack wave-front analyzer and Pentacam topography before surgery and 1, 3 and 6 months postoperatively.MTF of optic system was calculated and analyzed.The changes of MTF values were compared between the two groups at different time points under different spatial frequencies, after removal of low-order aberrations at postoperative 6 months, and after removal of vertical coma aberration, horizontal coma aberration and spherical aberration in the SMILE group at postoperative 6 months.The study protocol complied with the Declaration of Helsinki and was approved by an Ethics Committee of Tianjin Eye Hospital (No.TJYYLL-2014-17). Written informed consent was obtained from each patient before surgery.Results:Compared with the preoperative MTF, there were significant increases in postoperative 1-, 3- and 6-month MTF at all spatial frequencies in the SMILE group and FS-LASIK group (all at P<0.05). MTF values at all spatial frequencies in the SMILE group were significantly higher than those in the FS-LASIK group at 1, 3, and 6 months after surgery (all at P<0.05), except at 55 c/d and 60 c/d at 6 months postoperatively.The postoperative 6-month MTF values at all spatial frequencies without low-order aberration were higher in the SMILE group than those in the FS-LASIK group, showing significant differences between the two groups (all at P<0.05). In the SMILE group, the postoperative 6-month MTF values at 1 c/d spatial frequency without the horizontal coma aberration and spherical aberration were significantly higher than the preoperative MTF values (both at P<0.01); the postoperative 6-month MTF values at 1 c/d and 3 c/d spatial frequency without vertical coma aberration were significantly higher than the preoperative MTF values (both at P<0.05), and there were no statistically significant differences between the postoperative 6-month MTF values at the other spatial frequencies with and without single high-order aberrations (all at P>0.05). Conclusions:Optic quality has been obviously improved after SMILE and FS-LASIK, and the SMILE is superior to FS-LASIK in the MTF value.
