ABSTRACT

In the process of evolution, pathogenic Streptococcus pyogenes secretes an immunoglobulin G-degrading enzyme IdeS which can specifically cleave the hinge region of immunoglobulin G in order to escape the immune response against the host. On the one hand, IdeS can be used for IgG fingerprinting as a tool enzyme combined with mass spectrometry technology. On the other hand, IdeS can be used to treat the antibody-responsive diseases produced by autoimmunity as a therapeutic protein. In this study, the backbone of plasmid pCold was used to construct two expression vectors of recombinant protein IdeS, which were heterologously expressed in Escherichia coli Shuffle T7. After purification by affinity chromatography, the recombinant IdeS activity was detected and their activity differences between the two were compared. Among them, the yield of the recombinant IdeS containing the His6-tag at the N-terminus was 4 mg·L-1, and the cleavage reaction with antibody IgG1 at 1∶200 (m/m) at 37 ℃ for 30 min could complete. However, the yield of the recombinant IdeS containing both the N-terminal His6 tag and the C-terminal silica affinity tag (silica bing peptide, SiBP) is 1.5 mg·L-1, and the degradation reaction with antibody IgG1 at 1∶20 (m/m) at 37 ℃ for 30 min could reach the end. The C-terminal fusion peptide has a great influence on the yield and activity of IdeS, which is not conducive to subsequent application in drug development. Above all, the recombinant IdeS containing the His6-tag at the N-terminus expressed by this system has high activity and can fully meet the needs of antibody drug development and mapping analysis of IgG.

ABSTRACT

OBJECTIVE@#To systematically evaluate the efficacy of Shengmai San in patients with cardiotoxicity of anthracyclines.@*METHODS@#Randomized controlled trials (RCTs) were identified by searching China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database (CBM), PubMed, Cochrane Library, and Embase Databases from the inceptions until December 2020. The Cochrane Handbook was used to evaluate the risk of bias in the included studies. Data analysis was conducted using RevMan 5.3 software.@*RESULTS@#Totally 19 RCTs with 2,331 participants were included in this review. Results showed that in improving arrhythmia (13 RCTs, n=1,877, RR=0.37, 95%CI 0.25 to 0.52, P<0.00001), the treatment group was superior to the control group. In terms of reducing left ventricular end-diastolic diameter (LVEDD, 2 RCTs, n=128, MD=-0.79, 95%CI -0.93 to -0.65, P<0.00001) and left ventricular end systolic diameter (LVESD, 2 RCTs, n=128, MD=-0.58, 95%CI -0.82 to -0.35, P<0.00001), the treatment group was also better than the control group. In reducing myocardial enzymes such as creatine kinase (CK) [(3 RCTs, n=256, SMD=-0.80, 95%CI -1.16 to -0.44, P<0.0001), (2 RCTs, n=126, SMD=-0.62, 95%CI -0.98 to -0.26, P=0.0007)], the treatment group was superior to the control group.@*CONCLUSION@#Shengmai San has a positive effect on the treatment of cardiotoxicity from anthracyclines. However, in the future, it is still necessary to conduct high-quality RCTs to verify its efficacy.

ABSTRACT

OBJECTIVE@#To assess the efficacy and safety of mulberry twig alkaloids (Sangzhi alkaloids, SZ-A) for treatment of type 2 diabetes in a randomized, double-blind, placebo-controlled multicenter clinical trial.@*METHODS@#A total of 200 patients were randomized to receive SZ-A (n=100) or placebo (n=100) for 16 weeks. The data analysis system for electronic data capture clinical trial central randomization system was used for randomization and dispensing of drugs. The primary outcome was the change in glycosylated hemoglobin (HbA1c) level. The secondary outcome included the proportions of cases with HbA1c <7.0% and HbA1c <6.5%, fasting blood glucose (FBG), postprandial blood glucose (PBG), area under curve for the PBG (AUC0-2h), body weight, and body mass index (BMI). Adverse events (AEs), severe adverse events (SAEs), treatment-related adverse events (TAEs), gastrointestinal disorders (GDs), blood pressure, routine blood tests, and liver and kidney function were monitored.@*RESULTS@#Compared with baseline, the change of HbA1c at week 16 was -0.80% (95% CI: -0.98% to -0.62%) and -0.09% (95% CI: -0.27% to 0.09%) in SZ-A group and placebo group, respectively. The proportion of patients with HbA1c <7% and <6.5% was higher in the SZ-A group than in the placebo group (46.8% vs. 21.6% and 29.9% vs. 10.8%). The observed values and changes in FBG, 1 h-PBG, 2 h-PBG, and AUC0-2h differed significantly between groups (P<0.001), but differences were not significant in body weight and BMI (P>0.05). The incidence rates of AEs, TAEs, and GDs differed significantly between groups (P=0.010, P=0.005, and P=0.006, respectively), whereas the incidence rates of SAEs showed no significant differences between groups (P=1.000).@*CONCLUSION@#SZ-A are effective and safe for treatment of type 2 diabetes. The protocol was registered in http://www.chictr.org.cn/showproj.aspx?proj=60117 (ChiCTR2000038550).

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy, survival, and prognosis of autologous hematopoietic stem cell transplantation (ASCT) with new drug chemotherapy in the treatment of newly diagnosed multiple myeloma (NDMM) in the new drug era.@*METHODS@#The clinical data of 149 patients with NDMM treated with new drug induction regimen in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2012 to December 2019 were retrospectively analyzed. Twenty-four patients who received ASCT were in ASCT group, and 125 patients who did not receive ASCT were in non-ASCT group. The median follow-up time was 43 (1-90) months. The propensity score matching (PSM) method was used to balance confounding factors, then depth of response, overall survival (OS), and progression-free survival (PFS) between the two groups were compared and subgroup analysis was performed.@*RESULTS@#After matching, the covariates were balanced between the two groups. Fifty-one patients (15 cases in ASCT group and 36 cases in non-ASCT group) were included. ASCT patients had a better complete response (CR) rate than non-ASCT patients receiving maintenance therapy (93.3% vs 42.3%, P=0.004), while there were no statistical differences in deep response rate and overall response rate (ORR) between the two groups (93.3% vs 65.4%, P=0.103; 93.3% vs 96.2%, P=1.000). Before matching, the 3 and 5-year PFS rate and median PFS (mPFS) in ASCT group and non-ASCT group were [89.6% vs 66.5%, P=0.024; 69.8% vs 42.7%; non-response (NR) vs 51.0 months], and the 3 and 5-year OS rate and median OS (mOS) were (100% vs 70.6%, P=0.002; 92.3% vs 49.6%; NR vs 54.0 months). After matching, the 3 and 5-year PFS rate and mPFS in ASCT group and non-ASCT group were (83.6% vs 61.7%, P=0.182; 62.7% vs 45.7%; NR vs 51.0 months), the 3 and 5-year OS rate and mOS were (100% vs 65.6%, P=0.018; 88.9% vs 46.9%; NR vs 51.0 months). Subgroup analysis showed that patients with mSMART 3.0 high risk stratification, the 3-year PFS rate and mPFS in ASCT group and non-ASCT group were (83.3% vs 41.5%, P=0.091; NR vs 34.0 months), and the 3-year OS rate and mOS were (100% vs 41.5%, P=0.034; NR vs 34.0 months). Patients with mSMART 3.0 standard risk stratification, the 3-year PFS rate and OS rate in ASCT group and non-ASCT group were (83.3% vs 76.8%, P=0.672; 100% vs 87.2%, P=0.155). The 3-year PFS and OS rate in MM patients who achieved deep response within 3 months after transplantation compared with non-ASCT patients who achieved deep response after receiving maintenance therapy were (83.1% vs 56.7%, P=0.323; 100% vs 60.5%, P=0.042), and the 3-year PFS and OS rate in patients who achieved overall response in both groups were (83.1% vs 62.5%, P=0.433; 100% vs 68.1%, P=0.082). After matching, Cox multivariate regression analysis showed that mSMART 3.0 risk stratification and ASCT were independent prognostic factors for OS.@*CONCLUSION@#In the new drug era, ASCT can increase CR rate and prolong OS of NDMM patients. ASCT patients who are mSMART 3.0 high risk stratification or achieved deep response within 3 months after transplantation have better OS than non-ASCT patients receiving new drug chemotherapy. ASCT and mSMART 3.0 risk stratification are independent prognostic factors for OS in NDMM patients.

ABSTRACT

Objective To explore the nutritional risk influencing factors in stroke patients, and to discuss the formulation of rehabilitation nursing countermeasures. Methods We randomly selected 152 patients with acute hemorrhagic stroke admitted to our hospital from July 2018 to July 2020. Based on the results of the mini nutritional assessment (MNA) score, the patients were divided into normal group (49 cases), risk group (53 cases), and bad group (50 cases). Single factor analysis and correlation analysis were used to analyze the nutritional risk factors, and the countermeasures for the influencing factors were discussed. Results Univariate analysis showed that stroke time, mechanical ventilation, swallowing dysfunction, ADL score, upper arm muscle circumference, serum albumin, and total lymphocyte count in risk and bad groups were different from the normal group. In comparison, the proportion of patients with mechanical ventilation and swallowing dysfunction was higher, and ADL score, upper arm muscle circumference, serum albumin level and total lymphocyte count were lower (P<0.05). The Spearman rank correlation analysis showed that the factors with differences in the univariate analysis also showed correlation (P<0.05). Among them, the positive correlation factors included the duration of stroke, receiving mechanical ventilation, swallowing dysfunction, NIHSS score, negatively related factors included ADL score, serum levels of albumin, transferrin, and hemoglobin. Multivariate Logistic regression analysis showed that stroke time (OR=1.739, P<0.001) and swallowing dysfunction (OR=3.966, P=0.008) were independent risk factors for malnutrition. ADL score (OR=0.687, P<0.001), upper arm muscle circumference (OR=0.770, P=0.012), serum albumin level (OR=0.870, P=0.003) were independent protective factors for malnutrition. Conclusion The nutritional status in stroke patients is not optimistic. Most patients have swallowing disorders, motor dysfunction, and poor self-care ability. At the same time, the body protein content in patients has decreased significantly. The clinical work is needed to deal with the patients' swallowing function recovery together with the treatment of nerve damage.

ABSTRACT

Children with infantile cholestatic liver disease are often accompanied by malnutrition, which in turn can affect its progression and prognosis. There are many factors causing malnutrition and various methods for malnutrition assessment, but there is still a lack of uniform standard for nutritional assessment in patients with liver diseases, and a variety of indicators and methods are required for comprehensive analysis and assessment. This article analyzes the common causes of malnutrition in children with cholestatic liver disease, introduces the different methods for nutritional assessment, including anthropometric measurements, laboratory examination, and nutritional assessment tools, and elaborates on nutritional intervention treatment, so as to improve the understanding of nutritional problems in children with cholestatic liver disease. Early identification and rational interventions can help to improve the quality of life and prognosis of children.

ABSTRACT

ObjectiveTo investigate the compatibility rule of traditional Chinese patent medicines (TCPMs) against liver diseases through network analysis. MethodWith “liver” as the search term, TCPMs against liver diseases were retrieved from volume Ⅰ of Chinese Pharmacopoeia (2020 edition), and the basic information of them was collected. TCPMs with same Chinese medicinal materials (CMMs), usage, and indications, but different dosage forms, were unified as one formula. Mutual information entropy (MIE) of CMM couples was calculated to quantify the relationship between them, and the top 25% CMM pairs in MIE were used to construct the compatibility network, with CMM as node and the relationship between CMM pairs as the edge. Key CMM and frequently used CMM combinations were identified based on node centrality and cluster analysis, respectively. The indications of TCPMs related to the CMMs in clusters were recorded. Cytoscape 3.6.1 was employed for visualization and topology analysis of the compatibility network. ResultA total of 179 TCPMs, involving 428 CMMs, were retrieved. Angelicae Sinensis Radix, Paeoniae Radix Alba, and Glycyrrhizae Radix et Rhizoma were identified as key CMMs with high frequency, and Cuscutae Semen-Lycii Fructus, Citri Reticulatae Pericarpium-Cyperi Rhizoma, and Ecliptae Herba-Ligustri Lucidi Fructus combinations had high MIE. Furthermore, the CMMs were clustered into ten groups corresponding to different diseases which, however, all belonged to digestive diseases. ConclusionThis study unveils potential CMM pairs and common CMM combinations against liver diseases, which can serve as a reference for revealing compatibility rules of CMMs and research and development of Chinese medicine.

ABSTRACT

Da Jianzhongtang, which is from Synopsis of Golden Chamber(《金匮要略》), is one of the hundred ancient classical formulas. In this textual research, a total of 46 records on this prescription from 42 ancient books and 207 records from modern literature were screened out. Through systematic research on its name, dosage, processing, evolution of the meaning on prescription compatibility, indications, decocting methods, usage, and precautions, this paper aims to lay a literature basis for further research on Da Jianzhongtang. The results show that the converted dosages for the components are 3 g of Zanthoxyli Pericarpium, 12 g of Zingiberis Rhizoma, 6 g of Ginseng Radix et Rhizoma, and 30 g of Saccharum Granorum. The efficacy can be labeled on the prescription instruction as warming the middle and tonifying deficiency, descending adverse Qi and relieving pain. According to modern literature, the main indications include diseases in digestive system, circulatory system, orthopedic system, urinary system, and ophthalmic system, particularly the intestinal obstruction, gastric ulcer, chronic gastritis, and duodenal ulcer in the digestive system. The core pathogenesis of the above diseases is "deficiency-cold of middle energizer and internal exuberant cold". Precautions are as follows. ① For the processing of Zanthoxyli Pericarpium, stir-frying can alleviate its toxicity and increase the decoction rate of effective ingredients. ② For the dosage, overdosage will lead to dry cough, edema, etc. ③ As to the contraindications after the medication, raw, cold, or indigestible food should not be taken after medication. ④ For the syndrome taboos, this prescription should be used with caution for patents with Yin deficiency, congealing cold, and Qi stagnation, and be forbidden for patients with spleen and stomach dampness-heat. The above results lay a basis for the research and development of the compound preparation for Da Janzhongtang and provide a reference for its instructions.

ABSTRACT

The obstruction of post-insulin receptor signaling is the main mechanism of insulin-resistant diabetes. Progestin and adipoQ receptor 3 (PAQR3), a key regulator of inflammation and metabolism, can negatively regulate the PI3K/AKT signaling pathway. Here, we report that gentiopicroside (GPS), the main bioactive secoiridoid glycoside of Gentiana manshurica Kitagawa, decreased lipid synthesis and increased glucose utilization in palmitic acid (PA) treated HepG2 cells. Additionally, GPS improved glycolipid metabolism in streptozotocin (STZ) treated high-fat diet (HFD)-induced diabetic mice. Our findings revealed that GPS promoted the activation of the PI3K/AKT axis by facilitating DNA-binding protein 2 (DDB2)-mediated PAQR3 ubiquitinated degradation. Moreover, results of surface plasmon resonance (SPR), microscale thermophoresis (MST) and thermal shift assay (TSA) indicated that GPS directly binds to PAQR3. Results of molecular docking and cellular thermal shift assay (CETSA) revealed that GPS directly bound to the amino acids of the PAQR3 NH2-terminus including Leu40, Asp42, Glu69, Tyr125 and Ser129, and spatially inhibited the interaction between PAQR3 and the PI3K catalytic subunit (P110α) to restore the PI3K/AKT signaling pathway. In summary, our study identified GPS, which inhibits PAQR3 expression and directly targets PAQR3 to restore insulin signaling pathway, as a potential drug candidate for the treatment of diabetes.

ABSTRACT

OBJECTIVE@#To investigate the protective effects of Schisandra chinensis oil (SCEO) against aristolochic acid I (AA I)-induced nephrotoxicity in vivo and in vitro and elucidate the underlying mechanism.@*METHODS@#C57BL/6 mice were randomly divided into 5 groups according to a random number table, including control group, AA I group, and AA I +SCEO (0.25, 0.5 and 1 g/kg) groups (n=5 per group). Pretreatment with SCEO was done for 2 days by oral administration, while the control and AA I groups were treated with sodium carboxymethyl cellulose. Mice of all groups except for the control group were injected intraperitoneally with AA I (5 mg/kg) from day 3 until day 7. Histopathological examination and apoptosis of kidney tissue were observed by hematoxylin and eosin and TdT-mediated dUTP nick-end labeling (TUNEL) staining, respectively. The levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), and serum creatinine (SCr), as well as renal malondialdehyde (MDA), glutathione, r-glutamyl cysteingl+glycine (GSH), and superoxide dismutase (SOD) were analyzed using enzyme-linked immunosorbent assay (ELISA). Expressions of hepatic cytochrome P450 1A1 (CYP1A1), CYP1A2, and nad(p)hquinonedehydrogenase1 (NQO1) were analyzed using ELISA, quantitative real-time polymerase chain reaction (qPCR) and Western blot, respectively. In vitro, SCEO (40 µ g/mL) was added 12 h before treatment with AA I (40 µ mol/mL for 48 h) in human renal proximal tubule cell line (HK-2), then apoptosis and reactive oxygen species (ROS) were analyzed by flow cytometry.@*RESULTS@#SCEO 0.5 and 1 g/kg ameliorated histopathological changes and TUNEL+ staining in the kidney tissues of mice with AA I-induced nephrotoxicity, and reduced serum levels of ALT, AST, BUN and SCr (P<0.01 or P<0.05). SCEO 0.5 and 1 g/kg alleviated the ROS generation in kidney, containing MDA, GSH and SOD (P<0.01 or P<0.05). SCEO 1 g/kg increased the expressions of CYP1A1 and CYP1A2 and decreased NQO1 level in the liver tissues (P<0.01 or P<0.05). Besides, in vitro studies also demonstrated that SCEO 40 µ g/mL inhibited apoptosis and ROS generation (P<0.05 or P<0.01).@*CONCLUSIONS@#SCEO can alleviate AA I-induced kidney damage both in vivo and in vitro. The protective mechanism may be closely related to the regulation of metabolic enzymes, thereby inhibiting apoptosis and ROS production.

ABSTRACT

Objective@#To analyze the prevalence of dry and wet age-related macular degeneration (AMD) in patients with diabetes, hypertension and hyperlipidemia, and to analyze the risk factors for AMD.@*Methods@#A population-based cross-sectional epidemiologic study was conducted involving 14,440 individuals. We assessed the prevalence of dry and wet AMD in diabetic and non-diabetic subjects and analyzed the risk factors for AMD.@*Results@#The prevalence of wet AMD in diabetic and non-diabetic patients was 0.3% and 0.5%, respectively, and the prevalence of dry AMD was 17% and 16.4%, respectively. The prevalence of wet AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 0.5%, 0.3%, 0.2%, and 0.7%, respectively. The prevalence of dry AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 16.6%, 16.2%, 15.2%, and 17.2%, respectively. Age, sex, body mass index, and use of hypoglycemic drugs or lowering blood pressure drugs were corrected in the risk factor analysis of AMD. Diabetes, diabetes/hypertension, diabetes/hyperlipidemia, and diabetes/hypertension/hyperlipidemia were analyzed. None of the factors analyzed in the current study increased the risk for the onset of AMD.@*Conclusion@#There was no significant difference in the prevalence of wet and dry AMD among diabetic and non-diabetic subjects. Similarly, there was no significant difference in the prevalence of wet and dry AMD among subjects with hypertension and hyperlipidemia. Diabetes co-existing with hypertension and hyperlipidemia were not shown to be risk factors for the onset of dry AMD.

ABSTRACT

AIM:To evaluate the macular microstructural changes in patients with rhegmatogenous retinal detachment(RRD)after silicone oil tamponade by spectral-domain optical coherence tomography(SD-OCT).METHODS:From November 2019 to July 2021, 27 patients with 27 eyes in RRD who underwent vitrectomy combined with silicone oil tamponade in Cangzhou Aier Eye Hospital were enrolled in this study as the observation group, other 30 healthy volunteers with 30 eyes were included in the control group. The best corrected visual acuity(BCVA)of patients before and after operation were observed, and quantified evaluation of the postoperative macular microstructural changes were performed by SD-OCT.RESULTS: The BCVA(LogMAR)of the observation group at 1wk and 3mo after operation(0.61±0.23, 0.69±0.34)were improved compared with those before operation(1.43±0.77)(all P<0.01). The cube volume and average cube thickness in the macular area at 3mo after operation in the observation group were lower than those at 1wk and 1mo after operation in the control group(all P<0.05). There were no differences in the average ganglion cell-inner plexiform layer(GCIPL)thickness, minimum GCIPL thickness, average macular retinal nerve fiber layer(mRNFL)thickness and minimum mRNFL thickness at 1wk, 1 and 3mo after operation in the observation group, but all decreased compared with the control group(all P<0.01). There were 9 eyes with subretinal fluid(SRF)in the observation group during postoperative follow-up, SRF had a tendency to be gradually absorbed, but 1 eye had a secondary macular hole; 3 eyes had ellipsoid zone disruption, which had a tendency to be gradually repaired; 2 eyes had submacular perfluorocarbon liquid; 2 eyes had macular edema.CONCLUSION: SD-OCT can show the microstructure and morphological changes very well in macular area in patients with RRD after silicone oil tamponade, and has important clinical value for the preoperative and postoperative follow-up evaluation of RRD.

ABSTRACT

Objective:To analyze the composition, the changes of expense structure and the influencing factors of hospitalization expenses, for reference in optimizing the cost control of day surgery.Methods:Collection of the first page data of patients with the top three diseases(varicose veins of lower limbs, chronic cholecystitis and varicocele)in the day surgery volume ranking in three tertiary general hospitals in a city in 2020. The confounding factors were eliminated through propensity matching. The structural change of hospitalization expenses was analyzed by structural change degree, and the influencing factors of hospitalization expenses were analyzed by grey correlation degree and multiple linear regression.Results:After 1∶1 propensity matching of the first page data of 752 patients with day surgery and non day surgery, 98 patients with lower extremity varicose veins, 356 patients with chronic cholecystitis and 38 patients with varicocele were finally included. Compared with non day hand, the total hospitalization cost of day surgical instruments decreased, and the cost structure changes of chronic cholecystitis, varicocele and varicose veins of lower limbs were 14.59%, 6.20% and 16.20% respectively. Among them, the general medical service fee, nursing fee and examination and laboratory fee showed a downward trend, and the fees of materials and drugs showed an upward trend. General medical service fee, nursing fee, examination and laboratory fee, clinical diagnosis fee, treatment fee, drug fee, material fee and other expenses presented a high correlation with the cost of day surgery(grey correlation>0.90). The payment method, wound healing type and discharge diagnosis can influence the cost of day surgery( P<0.05). Conclusions:Compared with non daytime surgery, the total hospitalization cost of day surgery has a certain cost control effect, but it can not reduce the cost of all projects. The main influencing factors are the internal composition of the cost, payment method and so on. The hospitals should focus on tapping the internal cost control potential of day surgery and further expanding the coverage of day surgery diseases.

ABSTRACT

Objective:To explore the intervention effects of an Internet-based blood pressure monitoring and management platform in a prehypertensive population.Methods:One hundred and fifty-eight prehypertensive patients who were examined at the Third Xiangya Hospital in Changsha, China, from August to December 2019 were randomly divided into either the experimental or control groups using the random number table method. The experimental group utilized an Internet-based blood pressure monitoring and management platform, whereas the control group utilized regular telephone and SMS health management routines. The intervention duration was 12 months for both groups. Data were analyzed using descriptive analysis, t-tests, chi-square tests, χ 2 tests, and rank-sum tests. Results:Post intervention systolic blood pressure (124.79±9.71 mmHg) (1 mmHg=0.133 kPa) and diastolic blood pressure measurements (77.41±8.21 mmHg) of the participants in the experimental group were significantly lower than those before the intervention (128.29±5.10 mmHg and 79.99±6.01 mmHg, respectively), and significantly lower than those of the control group′s measurements after the intervention (130.00±7.78 mmHg and 80.33±7.90 mmHg, respectively) (all P<0.05). The blood pressure goal attainment rate was significantly higher in the experimental group (23.08%) than that of the control group (8.75%), with statistically significant differences within the experimental group before and after intervention, as well as between the groups post intervention ( P<0.05). Positive lifestyle changes, such as prehypertension knowledge score, active restriction and control of salt and oil intake, reduction of smoking, and exercising weekly, were significantly higher than those in the control group before the intervention (all P<0.05). Conclusion:The use of an Internet-based blood pressure monitoring and management platform can effectively help patients with prehypertension control their blood pressure levels, improve their knowledge about the condition, and improve their lifestyle choices.

ABSTRACT

Objective:To understand the iodine nutrition status of pregnant women in Wuhan, and to provide a basis for guiding pregnant women to supplement iodine scientifically and adjust the prevention and control strategy of iodine deficiency disorders.Methods:From May 2016 to September 2020, each district of 13 administrative districts in Wuhan was divided into 5 areas according to east, west, south, north and middle. One township (street) was selected from each area, and 20 pregnant women were selected from each township (street). Edible salt and urine samples were collected to detect the contents of salt iodine and urinary iodine. Salt iodine was determined by direct titration, Sichuan salt and other fortified edible salt by arbitration method; urinary iodine was detected by arsenic-cerium catalytic spectrophotometry. Salt iodine and urinary iodine were analyzed according to different years, regions (central and far urban areas), age [low age (< 25 years old), appropriate age (25 - 34 years old), old age (≥35 years old)], and pregnancy [early pregnancy (< 13 weeks), middle pregnancy (13 - 27 weeks), and late pregnancy (28 - 40 weeks)].Results:A total of 5 200 edible salt samples from pregnant women's homes were collected, and the median salt iodine was 24.41 mg/kg. Among them, there were 32 non-iodized salts, 4 962 qualified iodized salts, and 206 unqualified iodized salts. The coverage rate of iodized salt was 99.38% (5 168/5 200), and the consumption rate of qualified iodized salt was 95.42% (4 962/5 200). A total of 5 200 pregnant women's urine samples were tested, and the median urinary iodine was 161.24 μg/L. Urinary iodine < 150 μg/L was found in central urban area, early pregnancy, middle pregnancy, low age and old age pregnant women in 2016 (141.74, 149.00, 132.34, 135.17, 121.00 μg/L); in early pregnancy, middle pregnancy and old age pregnant women in 2017 (128.00, 149.00, 141.41 μg/L); and in middle pregnancy and old age pregnant women in 2020 (148.95, 138.00 μg/L), which was at iodine deficiency level.Conclusions:Pregnant women in Wuhan are generally at iodine appropriate level, but close to the lower limit of the appropriate value, some pregnant women are at risk of iodine deficiency. It is still necessary to pay close attention to iodine nutrition status of pregnant women, and advocate pregnant women to eat qualified iodized salt actively.

ABSTRACT

The main components of the gastric tumor stroma consist of cells in both the immune and non-immune microenvironments. The effectiveness of a series of therapeutic measures such as adjuvant chemotherapy is closely related to the composition of gastric tumor stroma. By analyzing the components in the gastric tumor stroma, we understand the characteristics of the constituents in the pathological structure of gastric cancer, and further explore the connection of each component of the stroma with pathological structure and regulatory mechanisms of stroma components on the occurrence and progression of gastric tumors. Combined with artificial intel-ligence technology to analyze the pathological features related to stroma components of tumor microenvironment, the dynamic changes of immune microenvironment and non-immune microen-vironment in gastric cancer are expected to reveal.

ABSTRACT

Objective:To explore the influence of Internet diversified rehabilitation medicine education on self-efficacy and quality of life in newly diagnosed breast cancer patients.Methods:A prospective study was performed in 130 newly diagnosed breast cancer patients admitted to Beijing Friendship Hospital, Capital Medical University from February 2020 to February 2021. According to the method of randomly number table, these patients were divided into control group and intervention group, 65 cases in each group.The control group was treated with routine treatment scheme, and the intervention group added the intervention of Internet diversified education of rehabilitation medicine on the basis of routine treatment scheme. Compared the general data of the two groups, the General Self-Efficacy Scale (GSES) and the cancer patients′ Quality of Life Questionnaire-Core 30 (QLQ-C30) were used to compare the self-efficacy levels of the two groups before operation, 4 months and 8 months after operation, evaluate the quality of life. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups; Chi-square test was used for comparison of enumeration data between groups. Results:Before operation, there was no significant difference in general data, GSES score and QLQ-C30 score between the two groups ( P> 0.05). Four months after operation, GSES scores [(27.39±4.68) score vs (25.91±3.18)score], somatic function [(65.50±4.34) score vs (63.07±5.42) score], cognitive function [(67.63±10.32) score vs (63.29 ± 11.36) score], role function [(50.82±10.80) score vs (45.59±13.94) score], and total quality of life [(63.47 ± 6.98) score vs (59.26±7.98)score] were compared between the intervention group and the control group, the difference was statistically significant ( P< 0.05). There was no significant difference in the scores of emotional function [(57.60±11.72) score vs (55.53±10.61) score] and social function [(49.86±12.11) score vs (46.13±10.25) score] ( P> 0.05). Eight months after operation, the GSES score [(28.82±3.31) score vs (26.73 ± 3.06) score] of patients in the intervention group and the control group, and the scores of functional areas and overall quality of life in QLQ-C30 score were significantly different ( P< 0.01). Conclusion:the Internet diversified rehabilitation medicine education has a significant effect on improving the self-efficacy of new breast cancer patients, and can improve the quality of life of patients.

ABSTRACT

OBJECTIVES@#To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China.@*METHODS@#A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined.@*RESULTS@#The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05).@*CONCLUSIONS@#It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

ABSTRACT

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.
