ABSTRACT

OBJECTIVES@#To study the value of bedside echocardiography in predicting persistent patency of the ductus arteriosus during the early postnatal period in very low birth weight (VLBW) infants.@*METHODS@#A retrospective analysis was performed for 51 VLBW infants who were admitted from March 2020 to June 2021, with an age of ≤3 days and a length of hospital stay of ≥14 days. According to the diameter of patent ductus arteriosus (PDA) on days 14 and 28 after birth, the infants were divided into three groups: large PDA group (PDA diameter ≥2 mm), small PDA group (PDA diameter <2 mm), and PDA closure group (PDA diameter =0 mm). The echocardiographic parameters measured at 72 hours after birth were compared among the three groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of the echocardiographic parameters in predicting persistent patency of the ductus arteriosus (PDA≥2 mm) at the ages of 14 and 28 days.@*RESULTS@#On day 14 after birth, there were 17 infants in the large PDA group, 11 in the small PDA group, and 23 in the PDA closure group. On day 28 after birth, there were 14 infants in the large PDA group, 9 in the small PDA group, and 26 in the PDA closure group. There were significant differences in gestational age, birth weight, rate of pulmonary surfactant use, and incidence rate of hypotension among the three groups (P<0.05). PDA diameter, end-diastolic velocity of the left pulmonary artery, left ventricular output, and left ventricular output/superior vena cava flow ratio measured at 72 hours after birth were associated with persistent patency of the ductus arteriosus at the ages of 14 and 28 days (P<0.05), and the ratio of the left atrium to aorta diameter was associated with persistent patency of the ductus arteriosus at the age of 28 days (P<0.05). The ROC curve analysis showed that the area under the curve that the PDA diameter measured at 72 hours after birth predicting the persistent patency of the ductus arteriosus at the ages of 14 and 28 days was the largest (0.841 and 0.927 respectively), followed by end-diastolic velocity of the left pulmonary artery, with the area under the curve of 0.793 and 0.833 respectively.@*CONCLUSIONS@#The indicators obtained by beside echocardiography at 72 hours after birth, especially PDA diameter and end-diastolic velocity of the left pulmonary artery, can predict persistent patency of the ductus arteriosus at the ages of 14 and 28 days in VLBW infants, which provides a basis for the implementation of early targeted treatment strategy for PDA.

ABSTRACT

Methotrexate (MTX) injection has a short half-life and significant toxic side effects. In order to overcome the demerits of MTX injection, MTX@COF was prepared for subcutaneous injection by loading MTX in crosslinked cyclodextrin metal-organic framework (COF) in this study. The cationic lipid material (2, 3-dioleoyl-propyl)-trimethylamine (DOTAP) was then coated on the MTX@COF surface by solvent evaporation. Different surface charge characteristics were observed in the coated MTX@COF@DOTAP with no significant change in particle morphology. The in vitro release behaviors of sustained-release particles were investigated in water and phosphate buffer (pH 7.4), and the in vivo release characteristics were evaluated for pharmacokinetics in rats. The in vitro release results showed that the cumulative release of MTX, MTX@COF and MTX@COF@DOTAP within 6 h was 92.70%, 36.31% and 18.19% in water, respectively; the cumulative release of MTX, MTX@COF and MTX@COF@DOTAP within 4 h was 90.82%, 79.37% and 58.30% in phosphate buffer, respectively; the results showed that MTX@COF can significantly delay the release of MTX, the modification to MTX@COF by DOTAP can further delay the release of MTX. Pharmacokinetic studies in rats showed that the mean retention time [MRT(0-t)] and the time to peak (Tmax) of the subcutaneous injection of MTX@COF@DOTAP group were significantly prolonged compared with the MTX@COF group and the MTX group. The area under the concentration-time curve [AUC(0-t)] of the MTX@COF@DOTAP subcutaneous injection group was 1.8 times high as that of the MTX group. In this study, MTX@COF@DOTAP particles had a certain sustained-release effect, and could prolong the bioavailability of MTX by subcutaneous injection, which provided a new idea for the development of new MTX dosage forms.

ABSTRACT

The purpose of the present study was to investigate the relationship of the classification of traditional Chinese medicine(TCM) materials with the suitable binder concentration and dosage in the preparation of personalized water-paste pills and establish a model for predicting the binder concentration and dosage. Five representative TCM materials were selected, followed by mixture uniform design. The water-paste pills were prepared by extrusion and spheronization with hypromellose E5(HPMC E5) as the binder. The quality of intermediates and final products was evaluated, and the resulting data were subjected to multivariate statistical analysis. The prediction models for binder concentration and dosage were established as follows: binder concentration: Y_1=0.378 6 + 0.570 1X_A + 2.271 2X_B-0.894 5X_C-0.458 2X_D-1.145 4X_E(when Y_1 < 0, 10% HPMC E5 was required; when Y_1 > 0, 20% HPMC E5 was required), with the accuracy reaching up to 100%; binder dosage: Y_2=32.38 + 0.25X_A + 1.85X_B-0.013X_B~2-0.002 5X_C~2(R~2=0.932 6, P < 0.001). The results showed that the binder concentration and dosage were correlated positively with the proportion of fiber material but negatively with the proportions of sugar material and brittle material. Then the validation experiments were conducted with the prediction models and all the prescriptions could be successfully prepared at one time. These demonstrated that following the classification of TCM materials and the calculation of their proportions in the prescription, the established mathematical model could be adopted for predicting the binder concentration and dosage required in the preparation of personalized water-paste pills, which contributed to reducing the pre-formulation research and guiding the actual production of personalized water-paste pills.

ABSTRACT

Chinese medicinals feature different medicinal parts and enriched components, which makes their powders show obvious microscopic identification characteristics and specific physical properties. On this basis, the commonly used Chinese medicinals can be divided into several categories, such as powdery, fibrous, sugar, oil, and brittle materials, which is of great importance to the research and development of personalized Chinese medicinal preparation technology. However, the existing classification methods are highly subjective and thus difficult to meet the requirements for the development of personalized Chinese medicinal preparations with high quality. In this study, 55 representative Chinese medicinals, such as Dioscoreae Rhizoma and Leonuri Herba, were selected, and the physical properties of their powders were systematically characterized by comprehensive powder tester, torque rheometer, texture analyzer, etc., based on which a data set encompassing physical properties of these powders was built. The typical physical fingerprints of powders from the above 5 categories were established by multivariate statistical analysis. Then, the Chinese medicinals were classified according to the Euclidean distance between each of them and the typical value in the PCA score plot. For those with multiple material properties, whose classification boundary was fuzzy, the proportions of different types of materials were calculated with the combination of Euclidean distance, powder properties, microscopic identification characteristics, and chemical composition, so as to achieve the multivariate quantitative classification of Chinese medicinals. This lays the foundation for the further creation of intelligent personalized Chinese medicinal preparation technology.

ABSTRACT

Objective:To investigate the role of interleukin-13(IL-13), interleukin-13 receptor α2(IL-13Rα2) and 11 β -hydroxysteroid dehydrogenase 2(11βHSD2) signaling pathway in liver metastasis of colon cancer and its mechanism.Methods:A retrospective case-control study was conducted to analyze the clinical data of 80 patients with colorectal cancer who were operated in Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from January 2015 to December 2018.All patients were followed up by clinic or telephone until August 30, 2019.According to the occurrence of liver metastasis, the patients were divided into metastasis group ( n=22) and non metastasis group ( n=58). Real-time fluorescence quantitative Polymerase Chain Reaction(PCR) and Western blotting were used to detect and compare the mRNA relative expression and protein expression of IL-13, IL-13Rα2, 11βHSD2, cyclooxygenase 2(COX 2) and protein kinase B in cancer tissues and cancer adjacent tissues. Glycyrrhetinic acid, an inhibitor of 11 β HSD2, was used to inhibit the activity of 11hsd2 in human colon cancer cell line HCT-8.The mRNA relative expression and protein expression of IL-13, IL-13Rα2, 11βHSD2, COX 2 and protein kinase B were detected by real-time fluorescence quantitative PCR and Western blotting before and 24 hours after glycyrrhetinic acid addition. Results:The mRNA relative expression of IL-13(0.79±0.11, 0.40±0.10), IL-13Rα2(0.72±0.13, 0.46±0.11), 11βHSD2(0.84±0.26, 0.60±0.08), COX 2(0.70±0.25, 0.37±0.04), protein kinase B (0.76±0.13, 0.42±0.06) in colon cancer tissues of metastatic and non metastatic groups were higher than those in cancer adjacent tissues(0.09±0.01, 0.10±0.06, 0.09±0.02, 0.09±0.03, 0.09±0.01, 0.09±0.02, 0.13±0.02, 0.12±0.07, 0.05±0.02, 0.05±0.03). The difference was statistically significant (t value was 28.36, 23.20, 22.07, 24.88, 16.47, 16.47, 47.86, 18.55, 24.55, 26.20, 44.40, all P<0.001). The protein expression of IL-13(0.48±0.11, 0.32±0.07), IL-13Rα2(0.52±0.11, 0.36±0.11), 11βHSD2(0.63±0.12, 0.48±0.11), COX2(0.45±0.15, 0.27±0.09), protein kinase B(0.50±0.12, 0.29±0.08) in colon cancer tissues of metastatic and non metastatic groups were higher than those in cancer adjacent tissues(0.12±0.02, 0.13±0.01, 0.10±0.02, 0.10±0.02, 0.14±0.06, 0.13±0.05, 0.10±0.03, 0.10±0.04, 0.10±0.03, 0.10±0.02). The difference was statistically significant ( t value were 15.63, 21.15, 17.71, 17.28, 11.01, 18.14, 10.55, 13.12, 15.76 and 18.90 respectively, all P<0.001). The relative expression of mRNA and protein in metastasis group was higher than that in non metastasis group ( t=15.15, 3.01, 8.97, 2.52, 6.34, 2.26, 9.82, 2.52, 16.02, 3.57, respectively, all P< 0.05). Compared with that those of before glycyrrhetinic acid addition, after 24 hours of glycyrrhetinic acid addition, the mRNA relative expression and protein expression of IL-13, IL-13Rα2 had no significant change (all P>0.05), while the mRNA relative expression and protein expression of COX 2 and protein kinase B(before adding: 0.725±0.159, 0.639±0.162, 0.741±0.178, 0.668±0.145, after adding: 0.108±0.085, 0.116±0.048, 0.122±0.063, 0.119±0.066) were decreased( t value were 18.744, 16.954, 17.956, 18.875 respectively , all P<0.01). Conclusion:The activation of IL-13/IL-13α2/11βHSD2 signaling pathway can promote liver metastasis of colon cancer.The mechanism may be that 11βHSD2 over expression promotes cancer cells invasion and migration-related COX2 expression and PI3K/protein kinase B pathway, and promotes liver metastasis of colon cancer.

ABSTRACT

Objective:To explore the effect of minimally invasive percutaneous pedicle screw internal fixation on the anterior height and Cobb angle of injured vertebra in patients with single vertebra magerl type A thoracolumbar fracture.Methods:71 cases of single vertebra magerl type A thoracolumbar fracture admitted in our hospital from January 2015 to January 2017 were reviewed. Among them, 31 patients who received minimally invasive percutaneous pedicle screw internal fixation were as the observation group, and 40 patients receiving open pedicle internal fixation were as control group. All the patients were followed up for one year, and the preoperative and postoperative indexes, the height of the anterior edge of the injured vertebra and Cobb angle, as well as the score of Oswestry dysfunction were compared between the two groups.Results:The length of incision and the time of descending were shorter in the observation group than in the control group, and the amount of bleeding during operation was less than in the control group ( P<0.05); there was no significant difference in operation time between the two groups ( P>0.05). There was no significant difference in serum creatine kinase (CK) and C-reaction protein (CRP) levels between the two groups ( P>0.05); the levels of serum CK and CRP in the two groups increased significantly after operation, and those in the control group were significantly higher than those in the observation group ( P<0.01). There was no significant difference in the height of anterior edge and Cobb angle between the two groups ( P>0.05); 7 days and 1 year after operation, the height of the anterior edge of the two groups was significantly higher than that before operation ( P<0.01), and the Cobb angle was significantly lower than that before operation ( P<0.01), but there was no significant difference between the two groups ( P>0.05). There was no significant difference in Oswestry dysfunction score between the two groups ( P>0.05); the scores of Oswestry dysfunction were significantly reduced in both groups 7 days and 1 year ater operation, and the observation group was significantly lower than the control group ( P<0.01). Conclusions:Minimally invasive percutaneous pedicle screw fixation can effectively improve the anterior height and Cobb angle of the injured vertebra in patients with single vertebra magerl A thoracolumbar fracture, and the perioperative indexes, serum inflammatory factors and Oswestry dysfunction scores are better than those of open pedicle internal fixation, which is worthy of clinical application.

ABSTRACT

To study the effect of Huangqin Qingre Chubi Capsules containing serum on the protein expressions of AMPK and FoxO3 a in peripheral blood mononuclear cells of patients with rheumatoid arthritis(RA), in order to explore the mechanism of anti-oxidation. Peripheral anticoagulant was collected from patients and normal people. Monocytes(PBMC) were isolated through density gradient centrifugation, and the logarithmic phase cells were cultured. Drug containing serum was prepared through intragastric admini-stration to SD rats. The rats were divided into five groups, namely normal group, model group, AMPK blocker group(compound C 10 μmol·L~(-1)), medium-dose HQC+AMPK blocker group, and middle-dose HQC group. The cell inhibition rate was calculated by MTT method. The levels of IL-1β, IL-4, LPO, MDA, SOD and TAOC were detected by ELISA. The expressions of AMPK, p-AMPK, p-FoxO3 a and FoxO3 a were detected by Western blot. The HQC containing serum had an inhibitory effect on human monocytes in peripheral blood. The best concentration was observed in middle-dose HQC, and the best time was 24 hours. Middle-dose HQC group was better than model group, AMPK blocker group and middle-dose HQC + AMPK blocker group in terms of increase of SOD, p-AMPK, p-FoxO3 a and decrease of LPO. It was better than model group and AMPK blocker group in terms of increase of IL-4, TAOC, AMPK, FoxO3 a and decrease of IL-1β, MDA. The differences were statistically significant(P<0.05 or P<0.01). The HQC containing serum may increase the levels of TAOC and SOD, decrease the level of MDA and LPO, activate AMPK, directly phosphorylate FOXO3 a, enhance its transcriptional activity, and improve the state of oxidative stress in RA patients.

ABSTRACT

BACKGROUND@#Benvitimod cream, a novel synthetic small molecule, was effective in treating mild-to-moderate plaque psoriasis. We conducted a phase III clinical trial to assess the efficacy and safety of benvitimod cream in patients with mild-to-moderate plaque psoriasis.@*METHODS@#We randomly assigned 686 patients (2:1:1) to receive 1% benvitimod cream, 0.005% calcipotriol ointment or placebo twice a day for 12 weeks. The primary efficacy end points were the percentage of patients with a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI 75) score and with a score of 0 or 1 in static physician's global assessment (sPGA) at week 12.@*RESULTS@#The results showed that 50.4% of patients in the benvitimod group achieved PASI 75, which was significantly higher than that in the calcipotriol (38.5%, P < 0.05) and placebo (13.9%, P < 0.05) groups. The proportion of patients achieving an sPGA score 0 or 1 was 66.3% in the benvitimod group and 63.9% in the calcipotriol group, which were both significantly higher than that in the placebo group (34%, P < 0.05). In the long-term follow-up study, 50.8% of patients experienced recurrence. After retreatment with 1% benvitimod, 73.3% of patients achieved an sPGA score of 0 or 1 again at week 52. Adverse events included application site irritation, follicular papules, and contact dermatitis. No systemic adverse reactions were reported.@*CONCLUSION@#During this 12-week study, benvitimod cream was demonstrated with high effectiveness and safety in patients with mild-to-moderate plaque psoriasis.@*TRIAL REGISTRATION@#Chinese Clinical Trial Registry (ChiCTR), ChiCTR-TRC-13003259; http://www.chictr.org.cn/showprojen.aspx?proj=6300.

ABSTRACT

@#AIM: To discuss the surgical method of foldable capsular vitreous body(FCVB)implantation and evaluate its therapeutic effect.<p>METHODS: We retrospectively analysis of 73 cases with severe ocular rupture injury after FCVB implanted and silicone oil dependence after vitrectomy in our Hospital from April 2018 to March 2020. The visual acuity, corneal, anterior chamber depth, intraocular pressure, retina, FCVB status, their satisfaction with appearance is observed after treated from 1-20mo.<p>RESULTS: All the 73 patients in this group were successfully operated. The amount of silicone oil injected into the FCVB during the operation was 2.4-4.2mL, with an average of 3.5±0.36mL. There were 22 eyes with light perception, 46 eyes with manual perception and 5 cases with immediate index; 19 eyes during postoperative follow-up. Corneal clarity or basic clarity was observed in 19 eyes, corneal local opacity in 31 eyes, and corneal grayish white opacity in 23 eyes. There were 32 eyes with normal anterior chamber, 23 eyes with shallow anterior chamber, and 18 eyes with completely disappeared anterior chamber. The intraocular pressure(IOP)could not be tested in 22 eyes due to cornea, 17 eyes with IOP less than 8mmHg, and 34 eyes with IOP between 8 and 21mmHg. Slit-lamp microscope examination showed no obvious deviation of the position of FCVB. The postoperative appearances were satisfactory and basically satisfactory in 52 eyes(71%). No balloon rejection, sympathetic ophthalmitis or other obvious surgical complications were observed in all cases.<p>CONCLUSION: For the patients with severe eyeball rupture and silicone-oil-dependent eyes, the FCVB implantation can prevent from eyeball extraction. The operation is safe and effective, and the eyeball shape and intraocular pressure can be well maintained.

ABSTRACT

OBJECTIVE@#To study the clinical features of neonatal enterovirus infection, especially severe enterovirus infection.@*METHODS@#A retrospective analysis was performed for the clinical data of 244 neonates with enterovirus infection. According to the severity of infection, they were divided into a common infection group with 231 neonates and a severe infection group with 13 neonates. Clinical features were compared between the two groups.@*RESULTS@#Of the 244 neonates, 207 (84.8%) developed the disease in May to October, with the highest number of patients in June to July. Compared with the common infection group, the severe infection group had a significantly lower gestational age at birth and a significantly higher proportion of preterm infants (P<0.05). Compared with the common infection group, the severe infection group had a significantly earlier onset time (P<0.05) and significantly higher incidence rates of skin petechiae and ecchymosis, respiratory symptoms, sepsis-like manifestations (poor appetite, crying less, and less movement), concomitant diseases (such as pneumonia, myocarditis, necrotic hepatitis, and coagulation disorder), thrombocytopenia, prolonged prothrombin time, elevated creatine kinase-MB, and elevated alanine aminotransferase (P<0.05). The severe infection group had a significantly higher mortality rate than the common infection group (P<0.05).@*CONCLUSIONS@#There are significant differences in onset time, common clinical manifestations, and concomitant diseases between the neonates with common and severe enterovirus infection. In the enterovirus epidemic season, if the neonates have rashes and/or sepsis-like manifestations such as poor appetite and less movement, especially if the laboratory tests suggest liver damage and coagulation dysfunction, it is necessary to pay particular attention to the possibility of severe enterovirus infection.

ABSTRACT

Nowadays, accumulating evidence indicates that long non-coding RNA (lncRNA) play vital roles in tumorigenesis. As a newly discovered lncRNA, FEZ family zinc finger 1-antisense RNA 1 (FEZF1-AS1) is markedly upregulated in various malignant tumors including non-small cell lung cancer (NSCLC). Aberrant expression of FEZF1-AS1 is related to clinical characteristics of patients with NSCLC and suggests poor prognosis. Moreover, FEZF1-AS1 can regulate numerous biological processes, such as cell proliferation, migration and invasion through different mechanisms. In this article, we systematically summarize the recent research progress of FEZF1-AS1 in NSCLC, which might be a novel target for clinical therapy.

ABSTRACT

To determine the relationship between the effect of wuzhi capsules on the blood concentration of tacrolimus as compared to diltiazem and with regard to cytochrome P450 (CYP)3A5 gene polymorphisms, 170 patients who underwent renal transplantation from November 2014 to March 2018 and used tacrolimus combined with diltiazem 30 mg bid were selected in this study retrospectively. Patients were divided into an observation group (105 patients) and a control group (65 patients) according to whether they used wuzhi capsules after the operation. The polymorphisms of CYP3A5*3 were determined and the effect of wuzhi capsules on the blood concentration of tacrolimus, as compared with that of diltiazem was determined in patients with different CYP3A5*3 genotypes. This study complies with relevant ethical norms. The results show that compared with diltiazem, an increase of tacrolimus C0/D was significantly correlated with the patient's CYP3A5*3 genotype in both the self-control and the control group. CYP3A5 expressers in the observation group were able to increase the tacrolimus C0/D by about 76.8% by replacing the wuzhi capsules with diltiazem, but this effect was not observed in CYP3A5 non-expressers. In CYP3A5 expressers wuzhi capsules had a greater ability relative to diltiazem to increase the blood concentration of tacrolimus.

ABSTRACT

OBJECTIVE@#To evaluate clinical effect of poking reduction cannulated screw based on Pingle orthopedic muscle-bone interoperability balance theory in treating Sanders Ⅱ calcaneal fracture.@*METHODS@#From October 2014 to December 2017, 28 patients with Sanders Ⅱ calcaneal fracture were treated with poking reduction cannulated screw guided by Pingle orthopedic muscle-bone interoperability balance theory, including 20 males and 8 females, aged from 24 to 55 years old with an average of (37.2±3.9) years old. Calcaneal width, Bhler angle, and Gissane angle were measured before and after operation, and Maryland Score before and 6 months after operation were compared.@*RESULTS@#All patients were followed up from 12 to 16 months with an average of (13.7±1.3) months. All fractures healed normally, and healing time ranged from 9 to 12 weeks with an average of (10.2±1.3) weeks. No postoperative wound infection, cortical necrosis, or osteomyelitis occurred. The width of the calcaneus decreased from (34.15±2.58) mm before surgery to (30.49±2.37) mm after surgery, Bhler angle increased from (14.16±3.27)° before operation to (31.95±3.07)°after operation, Gissane angle decreased from (128.45±9.04)° before operation to (120.83±8.15)° after operation. Maryland Score was 15.68±4.73 before operation, and was improved to 88.32±2.65 at 6 months after operation;19 patients got excellent result, 6 good, 2 fair and 1 poor.@*CONCLUSION@#Poking reduction cannulated screw based on Pingle orthopedic muscle-bone interoperability balance theory in treating Sanders Ⅱ calcaneal fracture has certain clinical effects, high acceptation of patient, and without special demand for soft tissue around fracture. But it should avoid choosing severe comminuted Sanders Ⅲand Ⅳcalcaneal fracture.
