ABSTRACT

Hepatitis B virus (HBV) infection is a major global public health issue. Clinical cure (also known as functional cure) of chronic hepatitis B (CHB) is the ideal therapeutic goal recommended by the latest guidelines for the prevention and treatment of CHB in China and globally. Optimized treatment regimens with direct-acting antiviral agents [e.g., nucleos(t)ide analogues] or immunomodulators (e.g., pegylated interferon-α) sequentially or in combination tend to have low cure rates. Rapid development has been achieved in the research and development of drugs for the treatment of CHB. This article reviews the clinical study of new antiviral drugs for CHB, including the selection of subjects, study design, dosage, dose escalation, adverse events, and efficacy evaluation. It is necessary to introduce the knowledge of quantitative pharmacology to analyze the association of drug exposure in body with efficacy and adverse reactions, and exploratory indicators should be incorporated for comprehensive analysis. This review provides related experience and new ideas for the clinical research and development of new anti-HBV drugs.

ABSTRACT

@#Objective    To investigate the influence of different discontinuation time of clopidogrel and aspirin before off-pump coronary artery bypass grafting on postoperative volume of drainage and blood products imported. Methods    A total of 454 patients who underwent coronary artery bypass grafting in Beijing Anzhen Hospital from January 2017 through December 2019 were included. According to the preoperative discontinuation of clopidogrel and aspirin, all the 454 patients were divided into three groups including a guide group, a non-stop group and a stop group. There were 86 patients in the guide group including 59 males and 27 females with an average age of 64.12±6.15 years. They continued to take aspirin 100 mg/d before operation, but stopped clopidogrel for more than 5 days. In the non-stop group, there were 234 patients including 141 males and 93 females with an average age of 63.71±7.01 years. They continued to take aspirin 100 mg/d before operation, and stopped clopidogrel <5 days. In the stop group, there were 134 patients including 76 males and 58 females with an average age of 62.90±7.78 years. They stopped aspirin and clopidogrel for more than 5 days before operation. The clinical effectiveness was compared among the three groups. Results    No perioperative death occurred in all patients. There was no statistical difference in platelet count, coagulation function, liver function, renal function, or myocardial markers among the groups (P>0.05). The hemoglobin [97 (15) g/ L vs. 98 (21) g/L vs. 100 (20) g/L, F=4.894, P=0.008] in the non-stop group was lower than that in the guide group and the non-stop group at 30 minutes postoperatively. The flow volume (399.87±127.19 mL vs. 367.05±125.89 mL vs. 349.63±130.68 mL, F=7.770, P=0.000) in the non-stop group at 3 hours postoperatively, the flow volume [600 (300) mL vs. 580 (245) mL vs. 550 (350) mL, Z=8.218, P=0.016] in the non-stop group at 6 hours postoperatively, the flow volume [750 (370) mL vs. 730 (350) mL vs. 730 (350) mL, Z=8.329, P=0.016] in the non-stop group at 12 hours postoperatively, the flow volume [890 (365) mL vs. 850 (340) mL vs. 850 (350) mL vs. Z=6.585, P=0.037] in the non-stop group at 24 hours postoperatively and the flow volume [950 (375) mL vs. 940 (360) mL vs. 940 (380) mL, Z=8.680, P=0.013] in the non-stop group at 48 hours postoperatively were more than those of the guide group and the stop group. The retention time of drainage tube was longer in the non-stop group [3 (1) d vs. 3 (1) d vs. 3 (1) d, Z=6.579, P=0.037] than in the guide group and the non-stop group. The amount of suspended erythrocytes input [0 (2) U vs. 0 (2) U vs. 0 (0) U, Z=6.150, P=0.046], and the amount of plasma input [200 (200) mL vs. 0 (200) mL vs. 0 (200) mL, F=4.144, P=0.016], the number of cases of plasma input (119 patients vs. 34 patients vs. 47 patients, Z=10.116, P=0.006) were more than those of the guide group and the stop group. Conclusion    Aspirin maintenance is recommended for patients before off-pump coronary artery bypass grafting. If not necessary, clopidogrel is discontinued for at least 5 days.

ABSTRACT

This study aimed to establish nomograms to preoperatively predict the possibility of testicular salvage (TS) in patients with testicular torsion. The clinical data of 204 patients with testicular torsion diagnosed at Xijing Hospital and Tangdu Hospital (Xi'an, China) between August 2008 and November 2019 were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to determine the independent predictors of TS. Based on multivariate regression coefficients, nomograms to predict possibility of TS were established. The predictive ability of the nomograms was internally validated by receiver operating characteristic (ROC) curves and calibration plots. The duration of symptoms ranged from 2 h to 1 month, with a median of 3.5 days. Thirty (14.7%) patients underwent surgical reduction and contralateral orchiopexy, while the remaining 174 (85.3%) underwent orchiectomy and contralateral orchiopexy. Finally, long symptom duration was an independent risk predictor for TS, while visible intratesticular blood flow and homogeneous testicular echotexture under color Doppler ultrasound were independent protective predictors. Internal validation showed that the nomograms, which were established by integrating these three predictive factors, had good discrimination ability in predicting the possibility of TS (areas under the ROC curves were 0.851 and 0.828, respectively). The calibration plots showed good agreement between the nomogram-predicted possibility of TS and the actual situation. In conclusion, this brief preoperative prediction tool will help clinicians to quickly determine the urgency of surgical exploration.

ABSTRACT

Dendrobium officinale is a sacred product for nourishing Yin and has a clear "thick gastrointestinal" effect. Modern pharmacological studies had found that it could improve gastrointestinal function. This study observed the improvement effect of D. officinale on constipation model mice with Yin deficiency caused by warm-drying medicine. It provided experimental basis for the treatment of Yin deficiency constipation. The male and female ICR mice were randomly divided into normal group, model group, D. officinale high, medium and low dose groups(0.6, 0.4, 0.2 g·kg~(-1)), and phenolphthalein tablets group. The model mice of Yin deficiency constipation were established by gavage with warm-drying medicine. The overall state and body temperature of the mice were observed and recorded. The number of feces, feces weight, fecal moisture content and intestinal propulsion were measured. The morphological damage of colon tissue was observed by hematoxylin-eosin(HE) staining. The expression of inducible nitric oxide synthase(iNOS) in the colon was detected by Western blot and immunohistochemical method. The expression of iNOS mRNA in the colon was detected by Real-time fluorescence quantitative PCR, and the serum cyclic guanosine phosphate(cGMP) level was detected the enzyme-linked immunosorbent assay(ELISA). The results showed that D. candidum could reduce the body temperature of mice with Yin deficiency constipation, increase the number of feces, wet feces, dry feces and intestinal propulsion ability, reduce the expression of iNOS protein and mRNA in the colon, and reduce the content of cGMP in the serum. It showed that D. candidum could improve the symptoms of Yin deficiency constipation mice caused by warm-drying medicine, and the mechanism may be related to reducing the expression of iNOS in the colon and increasing intestinal motility.

ABSTRACT

This study aims to investigate the preventive effect of Dendrobium officinale in LPS-induced intestinal mucosal damage. Forty SPF-grade C57 BL/6 J male mice were randomly divided into normal group(NC), model group(LPS), and two superfine powder groups of Dendrobium officinale(DOF)(DOF-L, 0.30 g·kg~(-1)and DOF-H, 0.60 g·kg~(-1), respectively), with 10 mice in each group. DOF superfine powder suspension was given via oral administration to mice for 7 days, while the mice in NC and LPS groups received the same volume of saline for 7 days. On the eighth day, the mice in LPS group and DOF treatment groups were injected with LPS(5 mg·kg~(-1)) by intraperitoneal injection to establish the intestinal mucosal injury model, while the mice in NC group were injected with the same volume of sterile saline in the same manner. Six hours after injection with LPS or saline, plasma and the intestinal tissue were collected. The diamine oxidase(DAO) and D-lactate levels in plasma were detected with a biochemical method. The levels of proinflammatory factors interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) in plasma were detected by ELISA. The histomorphology and ultrastructure of mouse ileum tissues were observed by hematoxylin-eosin(HE) staining in optical microscope and transmission electron microscope(TEM). The expression and distribution of tight junction(TJ) proteins claudin-1, occludin and F4/80 were detected by immunohistochemistry while the protein expression levels of Toll-like receptor 4(TLR-4) and nuclear factor kappa B p65(NF-κB p65) in jejunum were detected by Western blot. The experimental results showed that continuous intragastric administration of D. officinale superfine powder for 7 days obviously alleviated the damage and ultrastructural changes of intestinal mucosa induced by LPS; significantly decreased DAO and D-lactate levels in plasma in model group(P<0.05); up-regulated the protein expression of claudin-1 and occludin in ileum tissues; down-regulated the protein expression of TLR-4 and NF-κB p65 in jejunum tissues(P<0.01); significantly decreased TNF-α and IL-6 levels in plasma(P<0.05); and decreased the infiltration of F4/80~+ macrophage cells. Our results suggested that D. officinale had significant protective effects on LPS-induced intestinal mucosal damage and reduced intestinal permeability. The mechanism might be related to its effects of inhibiting inflammation via TLR-4/NF-κB p65, and up-regulating the expression of tight junction proteins.

ABSTRACT

Dendrobii officinalis, with a definite effect of nourishing Yin and clearing heat, has been a folk habit for drinking after being mixed with water. Because its superfine powder has the advantages of high dissolution and convenient drinking, we observed the effect of D. officinalis superfine powder on metabolic hypertension model rats and its possible mechanism in this experiment, which can be used as a reference for its clinical application for hypertension. The overeating greasy-induced metabolic hypertension model was established with high-fat, high-sugar and high-purine diet. These rats were orally administered with 400 mg·kg~(-1) and 200 mg·kg~(-1) of D. officinalis superfine powder for 20 consecutive weeks. During this period, blood pressure, blood lipid, blood glucose, insulin and other related indexes of glucose and lipid metabolism were monitored; the levels of lipopolysaccharide(LPS), C-reactive protein(CRP), interleukin 6(IL-6) and other inflammatory mediators were measured; the levels of nitric oxide(NO) and endothelin-1(ET-1) were detected, and the histomorphological and ultrastructural changes of aorta were observed. In addition, the expression of LPS/TLR4 pathway-related molecules in aorta was determined. The results showed that long-term administration of D. officinalis superfine powder significantly reduced the levels of systolic blood pressure(SBP), diastolic blood pressure(DBP) and mean arterial pressure(MBP) in metabolic hypertension model rats, decreased the levels of total cholesterol(TC), triglyceride(TG), low density lipoprotein cholesterol(LDL-c), glucose(Glu), and insulin(INS) levels in blood, increased the contents of high density lipoprotein cholesterol(HDL-c),decreased the LPS, CRP, IL-6 and ET-1 levels in blood and increased NO content. Furthermore, it improved the abnormality of aortic histomorphology and endothelial ultrastructure, and inhibited the protein expression of TLR4, myeloid differentiation factor(MyD88), IL-6, interleukin-1 β(IL-1β), and tumor necrosis factor-α(TNF-α) as well as mRNA expression of TNF-α and IL-1β in aorta. In conclusion, D. officinalis superfine powder may improve the abnormal function and structure of blood vessels by inhibiting the activation of LPS/TLR4 pathway, thus playing a role against metabolic hypertension.

ABSTRACT

Dendrobium officinale is a traditional Chinese medicine for nourishing Yin and benefiting stomach. Its superfine powder has many advantages, such as good dissolution, high utilization rate, strong integrity and easy to use. However, the researches on effect of D. officinale superfine powder on stomach Yin deficiency model are still not sufficient. In this experiment, we explored the effect of D. officinale superfine powder in mice model with stomach Yin deficiency caused by "spicy overeating", and provided certain reference value for its application in gastrointestinal diseases. Male ICR mice were randomly divided into normal group, model group, Yiweitang group, omeprazole group, and D. officinale superfine powder high, medium and low dose groups. The mixture of wine and pepper liquid was given by gavage administration for 30 d, and the corresponding drug was given for 60 d while the model was conti-nued. The body weight, food intake, water intake, fecal moisture content and particle number, foot temperature of mice were measured. The levels of serum gastrin(Gas), motilin(MTL) and somatostatin(SS) were measured by ELISA. Gastric histomorpho-logy was observed by HE staining. The expression levels of nuclear factor kappa B(NF-κB) and cyclooxygenase-2(COX-2) were determined by immunohistochemistry. The expression levels of B-cell lymphoma-2(Bcl-2) and Bcl-2 associated X protein(Bax) in gastric tissues were detected by Western blot. The results showed that D. officinale superfine powder could increase the food intake, water intake, fecal moisture content and particle number, reduce the foot temperature, improve the pathological changes of gastric mucosa, reduce the expression of NF-κB, COX-2 protein in gastric tissues, and increase the ratio of Bax/Bcl-2. D. officinale superfine powder can "nourish Yin and benefit the stomach", improve the syndrome of stomach Yin deficiency, such as "hunger but not want to eat, dry mouth but not want to drink, hand and feet hot, constipation", and reduce the damage of gastric mucosa. The mechanism may be related to regulating the secretion of gastrointestinal hormones, inhibiting the inflammation of gastric tissues and promoting the apoptosis of abnormal cells in gastric tissues.

ABSTRACT

The study is aimed to investigate the reproductive biology characteristics of Polygonatum cyrtonema, especially including phenology, flower bud differentiation, flowering timing, floral traits, pollen vigor and stigma receptivity. The results showed that P. cyrtonema forms inflorescence before the leaves spread. In the wild, P. cyrtonema is mainly pollinated by insects such as bumblebees, with a seed setting rate of 65.12%. The seed setting rate of indoor single plant isolation or self-pollination enclosed by parchment paper bag is 0, indicating that it is self-incompatible. In Lin'an city, seedlings begin to emerge from mid-March to early April(the temperature is higher than 7.5 ℃), buds begin to emerge from the end of March to mid-April, and then undergo the full bloom stage from mid-to-late April, and the final flowering stage from the end of April to mid-May. The whole flowering period lasts 36 to 45 days. There are obvious differences in the phenology of different provenances. The flowers come into bloom from the base to the top along the aboveground main axis, which usually contain 4-22 inflorescences with(2-) 4-10(-21) flowers per inflorescence. The flowering pe-riod for a single plant is 26-38 days. The single flower lasts about 20-25 days from budding to opening and withers 2 days after pollination, and then the ovary will gradually expand. If unpollinated, it will continue to bloom for 3-5 days and then wither. Flower development period is significantly related to pollen vigor and stigma remittance. The pollen viability is the highest when the flower is fully opened with anthers gathering on the stigma, and the receptivity is the strongest when the stigma protrudes out of the perianth and secretes mucus. The fruits and seeds ripen in October, and proper shading can ensure the smooth development and maturity of the seeds. This study provides a basis for the hybrid breeding and seed production of P. cyrtonema.

ABSTRACT

To systematically evaluate the clinical efficacy and safety of Danhong Injection combined with conventional therapy in improving diabetes mellitus complicated with coronary heart disease. Based on the online literature database(CNKI, Wanfang, VIP, PubMed, Web of Science, Cochran Library), the Chinese and English papers about the randomized controlled trial(RCT) of Danhong Injection in the treatment of diabetes mellitus complicated with coronary heart disease were searched comprehensively from the establishment of the databases to January 1, 2020. The papers were screened strictly according to the inclusion and exclusion criteria. Based on Jadad scale, the risk assessment of literature was carried out, and Meta-analysis was performed by STATA 12.0 software. Seventeen RCTs were included, involving 1 453 patients. The results of Meta-analysis showed that the combination of Danhong Injection and conventio-nal treatment could improve the clinical comprehensive effective rate(RR=1.47, 95%CI[1.38, 1.58], P<0.000 1), electrocardiogram(ECG) efficiency(RR=1.30, 95%CI[1.16, 1.46], P<0.000 1), efficiency of the angina pectoris(RR=1.41, 95%CI[1.25, 1.58], P<0.000 1), cholesterol level(SMD=-1.05, 95%CI[-1.95,-0.16], P=0.02), low-density lipoprotein(LDL) level(SMD=-0.50, 95%CI[-0.79,-0.21], P<0.000 1), coronary angina attack frequency(SMD=-3.71, 95%CI[-4.05,-3.36], P<0.000 1) and duration of angina pectoris(SMD=-2.96, 95%CI[-3.25,-2.66], P<0.000 1), with statistically significant differences. But the differences in fasting plasma glucose(FPG)(SMD=-0.19, 95%CI[-0.45, 0.08], P=0.16), plasma glucose of two hours after meal(2 hPG)(SMD=0.19, 95%CI[-0.11, 0.49], P=0.22), and high-density lipoprotein(HDL) level(SMD=0.10, 95%CI[-0.30, 0.49], P=0.62) after treatment were not statistically significant. Compared with the control group, there was no significant difference in adverse reactions(SMD=-2.96, 95%CI[-3.25,-2.66], P=0.75). The existing evidence shows that the combination of Western medicine and Danhong Injection can improve the clinical effect for diabetes mellitus complicated with coronary heart disease and has no obvious adverse reactions. However, due to the low level of overall literature evidence, high risk and some kind of publication bias, it still needs more high-quality randomized controlled trials and low-bias studies for further verification.

ABSTRACT

The aim of this paper was to study the improvement effect of ethanol extract from Citri Reticulatae Pericarpium(CRP) on triglyceride of hyperlipidemia model rats, and to explore the possible mechanism. SD rats were randomly divided into normal group, model group, positive control group, and high, medium and low-dose CRP ethanol extract groups, with 10 rats in each group. During the experiment, except for the normal group that was fed with distilled water and ordinary feed, rats in the other groups were given different concentrations of alcohol and fed with high-sugar and fat diets. All rats were given free diets. While being modeled, each group was administered with 0.01 mL·g~(-1) by gavage once a day for six weeks. Blood samples were collected after two weeks, four weeks and six weeks of drug treatment. After the completion of the experiment, blood, liver and adipose tissue were collected. Triglyceride(TG), alanine aminotransferase(ALT), aspartate aminotransferase(AST), alkaline phosphatase(ALP) in serum, TG in liver tissue and TG in fecal were detected. Free fatty acid(FFA) and triglyceride-related hydrolase, such as adipose tiglyceride lipase(ATGL), lipoprotein lipase(LPL), hepatic lipase(HL), hormone-sensitive triglyceride lipase(HSL) were detected by ELISA. The mRNA expressions of peroxisome proliferators-activated receptors(PPARγ), sterol regulatory element binding protein 1 c(SREBP-1 c) and farnesoid X receptor(FXR) were determined by RT-PCR. Compared with the model group, each administration group could reduce TG levels in serum and liver to varying degrees, reduce serum ALT, AST, ALP activities, significantly reduce free fatty acid content in serum, significantly increase triglyceride metabolism-related enzymes, including fat ATGL, LPL and liver HL content, and significantly reduced the content of fat HSL. According to the study of transcriptional regulation genes relating to triglyceride metabolism, extract from CRP could significantly increase the mRNA expressions of PPARγ and FXR. In conclusion, ethanol extract from CRP could ob-viously reduce the TG level of hyperlipidemia model rats, and might reduce plasma TG content by increasing PPARγ-LPL/ATGL and FXR-HL triglyceride hydrolysis pathways.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

BACKGROUND@#For patients with B cell acute lymphocytic leukemia (B-ALL) who underwent allogeneic stem cell transplantation (allo-SCT), many variables have been demonstrated to be associated with leukemia relapse. In this study, we attempted to establish a risk score system to predict transplant outcomes more precisely in patients with B-ALL after allo-SCT.@*METHODS@#A total of 477 patients with B-ALL who underwent allo-SCT at Peking University People's Hospital from December 2010 to December 2015 were enrolled in this retrospective study. We aimed to evaluate the factors associated with transplant outcomes after allo-SCT, and establish a risk score to identify patients with different probabilities of relapse. The univariate and multivariate analyses were performed with the Cox proportional hazards model with time-dependent variables.@*RESULTS@#All patients achieved neutrophil engraftment, and 95.4% of patients achieved platelet engraftment. The 5-year cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), and non-relapse mortality were 20.7%, 70.4%, 65.6%, and 13.9%, respectively. Multivariate analysis showed that patients with positive post-transplantation minimal residual disease (MRD), transplanted beyond the first complete remission (≥CR2), and without chronic graft-versus-host disease (cGVHD) had higher CIR (P  < 0.001, P = 0.004, and P  < 0.001, respectively) and worse LFS (P  < 0.001, P = 0.017, and P  < 0.001, respectively), and OS (P  < 0.001, P = 0.009, and P  < 0.001, respectively) than patients without MRD after transplantation, transplanted in CR1, and with cGVHD. A risk score for predicting relapse was formulated with the three above variables. The 5-year relapse rates were 6.3%, 16.6%, 55.9%, and 81.8% for patients with scores of 0, 1, 2, and 3 (P  < 0.001), respectively, while the 5-year LFS and OS values decreased with increasing risk score.@*CONCLUSION@#This new risk score system might stratify patients with different risks of relapse, which could guide treatment.

ABSTRACT

@#Objective    To explore the difference of myocardial injury between off-pump coronary artery bypass grafting (OPCAB) and modified perfusion on-pump coronary artery bypass grafting (ONCAB). Methods    A total of 558 patients who underwent coronary artery bypass grafting in Beijing Anzhen Hospital from 2017 to 2019 were included. According to whether or not they received modified perfusion cardiopulmonary bypass, all the 558 patients were divided into two groups including an OPCAB group (OP group) and an ONCAB group (ON group). There were 465 patients in the OP group including 282 males and 183 females with an average age of 63.58±7.87 years. In the ON group, there were 93 patients including 64 males and 29 females with an average age of 63.91±7.51 years. Creatine kinase MB (CK-MB) and cardiac specific troponin I (cTnI) were measured 24 hours before operation, 30 minutes after operation, 12 hours after operation, 36 hours after operation and 48 hours after operation. Results    No perioperative death occurred in all patients. CK-MB (5.00 ng/mL vs. 8.60 ng/mL, Z=–2.189, P=0.029) and cTnI (3.00 ng/mL vs. 7.80 ng/mL, Z=–5.307, P=0.000) in postoperative 12 hours in the ON group were less than those in the OP group. CK-MB (5.00 ng/mL vs. 5.60 ng/mL, Z=–2.280, P=0.023) and cTnI (0.10 ng/mL vs. 1.02 ng/mL, Z=–6.418, P=0.000) in postoperative 36 hours in the ON group were less than those in the OP group. cTnI (0.07 ng/mL vs. 0.81 ng/mL, Z=–1.946, P=0.032) in postoperative 48 hours in the ON group was less than that in the OP group. Conclusion    Compared with OPCAB, modified perfusion ONCAB has less myocardial damage.

ABSTRACT

Ten triterpenoid saponins were isolated and purified from the water extract of Glycyrrhiza glabra by polyamide resin combined with macroporous resin column chromatography, ODS medium pressure column chromatography and semi-preparative RP-HPLC. Their structures were elucidated by physicochemical properties, NMR and MS spectra, and determined as 3β-O-[β-D-glucuronpyranosyl-(1→2)-β-D-glucuronpyranosyl]-30β-O-β-D-glucuronpyranosyl-oleanane-11-oxo-12(13)-ene (1), 3β-O-[β-D-glucuronpyranosyl-(1→2)-β-D-glucuronpyranosyl]-30β-O-α-L-rhamnopyranosyl-oleanane-11-oxo-12(13)-en-22β,30-diol (2), uralsaponin C (3), licorice-saponin A3 (4), licorice-saponin P2 (5), 22β-acetoxyl-glycyrrhizin (6), macedonoside A (7), 29-hydroxyl-glycyrrhizin (8), licorice-saponin G2 (9), glycyrrhizin (10). Compounds 1 and 2 are two new compounds and named as licorice-saponin R3 and licorice-saponin S3.

ABSTRACT

Infants suffering from angiostrongylus eosinophilic meningitis (AEM) is rare, while AEM can cause severe consequences.The diagnostic value of high-throughput sequencing for AEM was studied by analyzing 2 AEM children (< 2 years old) in the Department of Neurology, Shenzhen Children′s Hospital in 2019.Case 1 mainly pre-sented intermittent fever, vomiting, mental fatigue and bregma bulge.Case 2 mainly manifested intermittent fever, cough, vomiting and convulsion.Due to hypereosinophils in patients′ peripheral blood and cerebrospinal fluid (CSF), and abundant DNA sequences from a cantonensis in CSF and positive antibody test, the patients were diagnosed with AEM.The patients were treated with albendazole to deworm, and small doses of methylprednisolone to reduce inflammation.The clinical characteristics of AEM infant are not typical, and high-throughput sequencing technology can assist the diagnosis of AEM.

ABSTRACT

Midpalatal corticotomy-assisted rapid maxillary expansion (MCRME) is a minimally invasive treatment of maxillary transverse deficiency (MTD) in young adults. However, the effect of MCRME on respiratory function still needs to be determined. In this study, we evaluated the changes in maxillary morphology and the upper airway following MCRME using computational fluid dynamics (CFD). Twenty patients with MTD (8 males, 12 females; mean age 20.55 years) had cone-beam computed tomography (CBCT) images taken before and after MCRME. The CBCT data were used to construct a three-dimensional (3D) upper airway model. The upper airway flow characteristics were simulated using CFD, and measurements were made based on the CBCT images and CFD. The results showed that the widths of the palatal bone and nasal cavity, and the intermolar width were increased significantly after MCRME. The volume of the nasal cavity and nasopharynx increased significantly, while there were no obvious changes in the volumes of the oropharynx and hypopharynx. CFD simulation of the upper airway showed that the pressure drop and maximum velocity of the upper airway decreased significantly after treatment. Our results suggest that in these young adults with MTD, increasing the maxillary width, upper airway volume, and quantity of airflow by MCRME substantially improved upper airway ventilation.

ABSTRACT

OBJECTIVE@#To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants.@*METHODS@#The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP.@*RESULTS@#The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation (@*CONCLUSIONS@#A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.
