Genetic analysis of the false positive trisomy 7 and false negative trisomy 18 by NIPT-PLUS / 中华医学遗传学杂志

OBJECTIVE@#To explore the cause of inconsistency between the results of trisomy 7 by expanded non-invasive prenatal testing (NIPT-PLUS) and trisomy 18 by prenatal diagnosis.@*METHODS@#A pregnant woman who received genetic counseling at Jiaozuo Maternal and Child Health Care Hospital on July 5, 2020 was selected as the study subject. NIPT-PLUS, systematic ultrasound and interventional prenatal testing were carried out. The middle segment and root of umbilical cord, center and edge of the maternal and fatal surface of the placenta were sampled for the validation by copy number variation sequencing (CNV-seq).@*RESULTS@#The result of NIPT-PLUS indicated that the fetus has trisomy 7. Systematic ultrasound has shown multiple malformations including atrioventricular septal defect, horseshoe kidney, and rocker-bottom feet. However, QF-PCR, chromosomal karyotyping analysis, and CNV-seq of amniotic fluid samples all showed that the fetus was trisomy 18. Validation using multiple placental samples confirmed that the middle segment of the umbilical cord contains trisomy 18, the center of the placenta contained trisomy 7, and other placental sites were mosaicism for trisomy 7 and trisomy 18. Notably, the ratio of trisomy 18 became lower further away from the umbilical cord.@*CONCLUSION@#The false positive results of trisomy 7 and false negative trisomy 18 by NIPT-PLUS was probably due to the existence of placental mosaicism. Strict prenatal diagnosis is required needed aneuploidy is detected by NIPT-PLUS to exclude the influence of placental mosaicisms.

Effectiveness of Acupoint Application in Patients with Pharyngeal Pain: Evidence from CHUNBO, A Prospective Real-World Study / 中国结合医学杂志

OBJECTIVE@#To assess the outcomes after acupoint application in patients with pharyngeal pain in a real-world settings, and analyze the characteristics of effective population and prescription characteristics of acupoint application.@*METHODS@#Based on CHUNBO platform, patients with pharyngeal pain who were candidates for acupoint application on the basis of physician-evaluation, were enrolled in a nationwide, prospective, 69-week multicenter observational study from August 2020 to February 2022. Propensity score matching (PSM) was used to match the confounding factors and the association rules were used to analyze the characteristics of effective population and prescription characteristics of acupoint application. Outcome assessments included the disappearance rate of pharyngeal pain (within 3, 7, and 14 days), disappearance time of pharyngeal pain, as well as adverse events.@*RESULTS@#Of 7,699 enrolled participants, 6,693 (86.9%) received acupoint application and 1,450 (21.7%) with non-acupoint application. After PSM, there were 1,004 patients each in the application group (AG) and non-application group (NAG). The disappearance rate of pharyngeal pain in the AG at 3, 7, and 14 days were all higher than those in the NAG (P<0.05). The disappearance time of pharyngeal pain in the AG were shorter than that in the NAG (logrank P<0.001, hazard ratio=1.51, 95% confidence interval: 1.41-1.63). The median age of effective cases was 4 years, mainly 3-6 years old (40.21%). The disappearance rate of pharyngeal pain in the application group with tonsil diseases was 2.19 times higher than that in the NAG (P<0.05). The commonly used acupoints for the effective cases were Tiantu (RN 22), Shenque (RN 8) and Dazhui (DU 14). The commonly used herbs for the effective cases were Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae. Among them, Natrii sulfas was applied to RN 8 most frequently (support 84.39%). A total of 1,324 (17.2%) patients experienced AEs, and mainly occurred in the AG, with significant difference in the incidence of AEs between goups (P<0.05). All AEs reported were the first grade, and the average regression days of AEs was 2.8 days.@*CONCLUSIONS@#Acupoint application in patients with pharyngeal pain resulted in improved effective rate and shortened duration, especially children aged 3-6 years old, and those with tonsil diseases. Acupoint of RN 22, RN 8 and DU 14, Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae were the most commonly used herbs in the treatment of pharyngeal pain.

Comparing the prognostic value of 3 diagnostic criteria of bronchopulmonary dysplasia in preterm infants / 中华儿科杂志

Objective: To compare the prognostic value of 3 diagnostic criteria of bronchopulmonary dysplasia (BPD) in preterm infants with gestational age<32 weeks. Methods: The retrospective cohort study was conducted to collect the clinical data of 285 preterm infants with BPD admitted to the Department of Neonatology, Children's Hospital Affiliated to Zhengzhou University from January 2019 to September 2021, who were followed up regularly after discharge. The primary composite adverse outcome was defined as death or severe respiratory morbidity from 36 weeks of corrected gestational age to 18 months of corrected age, and the secondary composite adverse outcome was defined as death or neurodevelopmental impairment. According to the primary or secondary composite adverse outcomes, the preterm infants were divided into the adverse prognosis group and the non-adverse prognosis group. The 2001 National Institute of Child Health and Human Development (NICHD) criteria, 2018 NICHD criteria, and 2019 Neonatal Research Network (NRN) criteria were used to diagnose and grade BPD in preterm infants. Chi-square test, Logistic regression analysis, receiver operating characteristic (ROC) curve and Delong test were used to analyze the prognostic value of the 3 diagnostic criteria. Results: The 285 preterm infants had a gestational age of 29.4 (28.1, 30.6) weeks and birth weight of 1 230 (1 000, 1 465) g, including 167 males (58.6%). Among 285 premature infants who completed follow-up, the primary composite adverse outcome occurred in 124 preterm infants (43.5%), and the secondary composite adverse outcome occurred in 40 preterm infants (14.0%). Multivariate Logistic regression analysis showed that severe BPD according to the 2001 NICHD criteria, gradeⅡand Ⅲ BPD according to the 2018 NICHD criteria and grade 2 and 3 BPD according to the 2019 NRN criteria were all risk factors for primary composite adverse outcomes (all P<0.05). ROC curve showed that the area under the curve (AUC) of the 2018 NICHD criteria and 2019 NRN criteria were both higher than that of the 2001 NICHD criteria (0.70 and 0.70 vs. 0.61, Z=4.49 and 3.35, both P<0.001), but there was no significant difference between the 2018 NICHD and 2019 NRN criteria (Z=0.38, P=0.702). Multivariate Logistic regression analysis showed that the secondary composite adverse outcomes were all associated with grade Ⅲ BPD according to the 2018 NICHD criteria and grade 3 BPD according to the 2019 NRN criteria (both P<0.05). ROC curve showed that the AUC of the 2018 NICHD criteria and 2019 NRN criteria were both higher than that of the 2001 NICHD criteria (0.71 and 0.71 vs. 0.58, Z=2.93 and 3.67, both P<0.001), but there was no statistically significant difference between the 2018 NICHD and 2019 NRN criteria (Z=0.02, P=0.984). Conclusion: The 2018 NICHD and 2019 NRN criteria demonstrate good and comparable predictive value for the primary and secondary composite adverse outcomes in preterm infants with BPD, surpassing the predictive efficacy of the 2001 NICHD criteria.

OBJECTIVE To investigate the effects of esketamine for multimodal analgesia on opioid consumption and gastric motility in mechanically ventilated non-surgical intensive care unit （ICU） patients. METHODS Forty cases of mechanically ventilated non-surgical patients in the ICU of our hospital from February 1st， 2023 to July 31st， 2023 were selected and randomly divided into control group and esketamine （S-K） group using grouping method with opaque envelopes， with 20 cases in each group. Control group was given sufentanil， and S-K group was infused with Esketamine hydrochloride injection at a constant rate of 0.2 mg/（kg·h）+ sufentanil. The treatment period length， analgesic compliance rate， sedation level， analgesic and sedative consumption， and gastric motility indexes were compared between the two groups. RESULTS There was no statistically significant difference in the treatment period length， analgesic compliance rate， sedation level， or the consumption of propofol and midazolam between the two groups （P＞0.05）. The consumption of sufentanil in the S-K group was significantly less than control group （P＜ 0.05）. Compared with 1 h after randomization， the antral contraction frequency， antral contraction amplitude and antral motility index of patients in the S-K group were significantly higher at 72 h after randomization and were significantly higher than control group （P＜0.05）. CONCLUSIONS Esketamine may reduce opioid consumption and improve gastric motility in mechanically ventilated non-surgical ICU patients while ensuring a level of analgesic sedation.

Clinical study of rhegmatogenous retinal detachment treatment with minimally invasive foldable capsular buckle scleral buckling / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To investigate the clinical efficacy of minimally invasive foldable capsular buckle(FCB)scleral buckling in treating rhegmatogenous retinal detachment(RRD).METHOD: This retrospective study enrolled 11 patients(11 eyes)with RRD treated with minimally invasive FCB scleral buckling at the Hainan Traditional Chinese Medicine Hospital from May to July 2023. The surgeries were performed without subconjunctival anesthesia, extraocular muscle pulling, intraocular positioning, retinal cryotherapy or drainage of subretinal fluid, or FCB suture fixation. Furthermore, the best corrected visual acuity(BCVA), intraocular pressure and complications were observed.RESULTS: Minimally invasive FCB scleral buckling was performed on 11 eyes, with successful retinal reattachment in 10 eyes(91%), and the remaining 1 eye(9%)had postoperative retinal re-detachment and underwent vitrectomy with silicone oil filling for multiple retinal tears. One-time successful surgery was in 4 eyes(40%), gas injection in vitreous body after the surgery was performed in 1 eye(10%), FCB position adjustment after the surgery was performed in 3 eyes(30%), gas injection in vitreous body and FCB position adjustment after the surgery were performed in 2 eyes(20%); and FCB was removed 4-12 wk after the surgery in 5 eyes(50%), without retinal redetachment. The average BCVA(LogMAR)of the 10 eyes improved from 1.30±1.10 before surgery to 0.37±0.39 at 4 wk after surgery(P&#x0026;#x003C;0.01); the average preoperative intraocular pressure was 11.51±3.37 mmHg and 13.72±2.57 mmHg at 4wk after surgery(P&#x0026;#x003E;0.05). No serious complications occurred.CONCLUSION:Minimally invasive FCB scleral buckling effectively treats RRD with minimal injury, simple operation, time-saving, and fewer complications.

Surgical treatment strategies for pancreatic cancer with simultaneous liver metastasis / 中华外科杂志

Objective: To explore the outcome of different treatment strategies in patients with pancreatic cancer with synchronous liver metastasis (sLMPC). Methods: A retrospective analysis of the clinical data and treatment results of 37 patients with sLMPC treated in China-Japan Friendship Hospital was performed from April 2017 to December 2022. A total of 23 males and 14 females were included,with an age(M(IQR)) of 61 (10) years (range: 45 to 74 years). Systemic chemotherapy was carried out after pathological diagnosis. The initial chemotherapy strategy included modified-Folfirinox, albumin paclitaxel combined with Gemcitabine, and Docetaxel+Cisplatin+Fluorouracil or Gemcitabine with S1. The possibility of surgical resection (reaching the standards of surgical intervention) was determined after systemic treatment,and the chemotherapy strategy was changed in the cases of failed initial chemotherapy plans. The Kaplan-Meier method was used to estimate the overall survival time and rate,while Log-rank and Gehan-Breslow-Wilcoxon tests were used to compare the differences of survival curves. Results: The median follow-up time for the 37 sLMPC patients was 39 months,and the median overall survival time was 13 months (range:2 to 64 months) with overall survival rates of 1-,3-,and 5-year of 59.5%,14.7%,and 14.7%,respectively. Of the 37 patients,97.3%(36/37) initially received systemic chemotherapy, 29 completed more than four cycles,resulting in a disease control rate of 69.4% (partial response in 15 cases,stable disease in 10 cases,and progressive disease in 4 cases). In the 24 patients initially planned for conversion surgery,the successful conversion rate was 54.2% (13/24). Among the 13 successfully converted patients,9 underwent surgery and their treatment outcomes were significantly better than those (4 patients) of those who did not undergo surgery (median survival time not reached vs. 13 months,P<0.05). Regarding the 9 patients whose conversion was unsuccessful, no significant differences were observed in median survival time between the surgical group (4 cases) and the non-surgical group (5 cases) (P>0.05). In the allowed-surgery group(n=13),the decreased in pre-surgical CA19-9 levels and the regression of liver metastases were more significant in the successful conversion sub-group than in the ineffective conversion sub-group;however, no significant differences were observed in the changes in primary lesion between the two groups. Conclusion: For highly selective patients with sLMPC who achieve partial response after receiving effective systemic treatment,the adoption of an aggressive surgical treatment strategy can significantly improve survival time;however, surgery dose not provide such survival benefits in patients who do not achieve partial response after systemic chemotherapy.

Preparation and quality evaluation of total flavonoids microemulsion of "Pueraria lobata-Hovenia dulcis" / 中国中药杂志

The effective components of flavonoids in the "Pueraria lobata-Hovenia dulcis" drug pair have low bioavailability in vivo due to their unstable characteristics. This study used microemulsions with amphoteric carrier properties to solve this problem. The study drew pseudo-ternary phase diagrams through titration compatibility experiments of the oil phase with emulsifiers and co-emulsifiers and screened the prescription composition of blank microemulsions. The study used average particle size and PDI as evaluation indicators, and the central composite design-response surface method(CCD-RSM) was used to optimize the prescription; high-dosage drug-loaded microemulsions were obtained, and their physicochemical properties, appearance, and stability were evaluated. The results showed that when ethyl butyrate was used as the oil phase, polysorbate 80(tween 80) as the surfactant, and anhydrous ethanol as the cosurfactant, the maximum microemulsion area was obtained. When the difference in results was small, K_(m )of 1∶4 was chosen to ensure the safety of the prescription. The prescription composition optimized by the CCD-RSM was ethyl butyrate(16.28%), tween 80(9.59%), and anhydrous ethanol(38.34%). When the dosage reached 3% of the system mass, the total flavonoid microemulsion prepared had a clear and transparent appearance, with average particle size, PDI, and potential of(74.25±1.58)nm, 0.277±0.043, and(-0.08±0.07) mV, respectively. The microemulsion was spherical and evenly distributed under transmission electron microscopy. The centrifugal stability and temperature stability were good, and there was no layering or demulsification phenomenon, which significantly improved the in vitro dissolution of total flavonoids.

Resource components and utilization values of different parts of Panax quinquefolium in Shandong province / 中国中药杂志

To explore the resource components and availability of different parts of Panax quinquefolium in Shandong province, the paper employed the non-targeted metabolomics technology based on ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) to analyze the metabolites and their metabolic pathways in the root, fibril, stem, and leaf of P. quinquefolium. The content of seven ginsenosides and polysaccharides in different parts was determined by high performance liquid chromatography(HPLC) and ultraviolet-visible spectrophotometry(UV-Vis). The results showed that the metabolites were mainly sugars, glycosides, organic acids, amino acids and their derivatives, terpenoids, etc. The total abundance of metabolites followed the trend of leaf > root > fibril > stem. Most of the differential metabolites were concentrated in phenylpropane biosynthesis, flavonoid biosynthesis, citric acid cycle, and amino acid biosynthesis. The leaf contained high levels of sugars, glycosides, amino acids and their derivatives, and flavonoids; the root was rich in terpenoids, volatile oils, vitamins, and lignin; the fibril contained rich organic acids; and the stem had high content of nucleotides and their derivatives. The content of ginsenosides Re and Rb_1 was significantly higher in the root; the content of ginsenosides Rg_1, Rg_2, Rd, F_(11), and polysaccharide was significantly higher in the leaf; and the content of ginsenoside Rb_2 was significantly higher in the stem. We analyzed the resource components and availability of different parts of P. quinquefolium, aiming to provide basic information for the comprehensive development and utilization of P. quinquefolium resources in Shandong province.

Effects of flurochloridone on apoptosis and Nrf2/HO-1 and NFκB signaling pathways in mouse testis and TM4 cells / 环境与职业医学

Background Flurochloridone (FLC) is toxic to male reproduction and can induce apoptosis of testicular tissue and supporting cells under oxidative stress. Of particular concern is whether nuclear factor-erythrocyte 2-related factor 2/heme oxygenase-1 (Nrf2/HO-1) signaling pathway and nuclear factor kappa B (NFκB) signaling pathway participate this process. Objective To observe apoptosis of testicular tissue and sertoli TM4 cells and alterations of Nrf2/HO-1 and NFκB signaling pathways in mice treated with FLC in vivo/in vitro. Methods (1) Animal experiment. Testis samples were harvested from male C57BL/6 mice after 28-day FLC (0, 3, 15, 75, and 375 mg·kg−1 per day) exposure via oral route. Malondialdehyde (MDA) and superoxide dismutase (SOD) in homogenate of testicular tissue were measured by colorimetry. Apoptosis of testicular tissue was evaluated by TUNEL staining. Expression and distribution of Nrf2 and NFκB were detected by immunohistochemistry. Protein expression levels of Nrf2, HO-1, NAD(P)H: quinone oxidoreductase 1 (NQO1), NFκB, inhibitor of nuclear factor kappa-B kinase subunit beta (IKKβ), and phosphorylated recombinant inhibitory subunit of nuclear factor kappa-B alpha (P-IκBα) in testicular tissue homogenate were determined by Western blotting. (2) Cell experiment. TM4 cell lines were treated with 40, 80, 120, 160, and 200 μmol·L−1 FLC for 6 h, and cell viability was detected by CCK-8. After 6 h exposure to 40, 80, and 160 μmol·L−1 FLC, the apoptosis rate was detected by flow cytometry, and the protein expression levels of Nrf2, HO-1, NQO1, NFκB, IKKβ, and IκBα were detected by Western blotting. Results (1) Animal experiment. Apoptosis occurred in the interstitial and basal parts of spermatogenic tubules in male C57BL/6 mice after 28 days of oral FLC exposure. Compared with the control group, the MDA level in testicular tissue of the 375 mg·kg−1 FLC-treated group was significantly increased (P<0.05), and the SOD activity was significantly decreased (P<0.05). After 375 mg·kg−1 FLC exposure, apoptosis occurred in the interstitial and basal parts of spermatogenic tubules. The results of immunohistochemistry showed the expression of Nrf2 and NFκB in the interstitium and basal part of spermatogenic tubules of the treated groups. Compared with the control group, the protein levels of Nrf2, NQO1, P-IκBα, NFκB, and IKKβ in the 15, 75, and 375 mg·kg-1 groups were significantly increased (P<0.001), and the HO-1 protein level was significantly increased in the 375 mg·kg−1 group (P<0.001). (2) Cell experiment. Compared with the control group, the TM4 cell viabilities in the 40, 80, 120, 160, and 200 μmol·L−1 FLC-treated groups significantly decreased (P<0.01). The apoptosis rates were significantly increased (P<0.05), and the apoptosis rates increased from 5.7% in the control group to 7.4%, 9.4%, and 11.7% in the 40, 80, and 160 μmol·L−1, respectively. The Nrf2 protein level in the 40 μmol·L−1 group was significantly increased (P<0.01), while the levels significantly decreased in the 80 and 160 μmol·L−1 groups (P<0.01). The HO-1 protein levels in the 40, 80, and 160 μmol·L−1 groups were significantly increased (P<0.01). The level of NQO1 protein in the 40 μmol·L−1 group was significantly increased (P<0.01). The NFκB protein levels were significantly increased in the 80 and 160 μmol·L−1 groups (P<0.001). The IκBα protein levels were significantly decreased in all treated groups (P<0.001). The IKKβ protein had no significant change. Conclusion FLC induces testicular tissue apoptosis, and the process affects Nrf2/HO-1 signaling pathway and NFκB signaling pathway. The in vitro study confirms that FLC could induce apoptosis of TM4 cells and activate Nrf2/HO-1 and NFκB signaling pathways.

Screening status of neonatal fundus disease and its influencing factors in Longhua district, Shenzhen / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the screening status of neonatal fundus disease and the related influencing factors of common fundus retinal hemorrhage in Longhua District of Shenzhen, so as to provide references for the prevention, screening and intervention of neonatal fundus disease in clinical practice.METHODS: A total of 3 101 neonates who received fundus screening in the People's Hospital of Longhua, Shenzen from September 2019 to October 2022 were selected as research objects. The screening results were summarized, and the risk factors for neonatal retinal hemorrhage were analyzed by Logistic regression model.RESULTS: The detection rate of neonatal fundus abnormalities was 12.71%, and the detection rate of neonatal retinal hemorrhage was the highest(12.19%). The other types of fundus abnormalities included periretinal white focus, chromatosis, pigment shedding, choroid coloboma and nystagmus. Hemorrhage grade I accounted for the largest proportion of 378 neonates with retinal hemorrhage(75.66%). Follow-up found that different grades of retinal hemorrhage could be automatically absorbed over time without excessive intervention. Logistic analysis suggested that spontaneous delivery [OR=3.180, 95%CI(1.543～6.555)], twin pregnancy [OR=2.119, 95%CI(1.121～4.007)] and umbilical cord round the neck [OR=1.547, 95%CI(1.239～1.930)] were risk factors affecting neonatal retinal hemorrhage.CONCLUSION: Retinal hemorrhage is the most common type of fundus abnormalities in neonates. Spontaneous delivery, twin pregnancy and umbilical cord around the neck are risk factors of retinal hemorrhage. It is recommended that pay attention to the above factors and choose appropriate intervention means to avoid serious fundus complications.

Comparison of Blood Routine Changes in Treatment of Aplastic Anemia by Kidney-tonifying and Blood-generating Method and Qi-promoting and Blood-nourishing Method and Mode of Treatment by Stages / 中国实验方剂学杂志

ObjectiveTo explore the clinical effect of kidney-tonifying and blood-generating method and qi-promoting and blood-nourishing method combined with western medicine on the treatment of aplastic anemia and the characteristics of blood routine recovery， and to explore a new phased treatment model for aplastic anemia. MethodThis study was based on a prospective， multicenter， double-blind， and randomized controlled clinical trial. Patients with aplastic anemia from 19 centers were analyzed and divided into a kidney-tonifying and blood-generating group and a Qi-promoting and blood-nourishing group， which were treated with traditional Chinese medicine （TCM） combined with western medicine. The clinical effect and the changes in blood routine in each group during treatment were evaluated. ResultDuring the observation period， 375 cases of aplastic anemia were included in two groups， and TCM syndrome differentiation conformed these cases as Qi-deficiency type and both Qi and blood-deficiency type. These cases were randomly divided into two groups， including 184 in the kidney-tonifying and blood-generating group and 191 in the Qi-promoting and blood-nourishing group， being treated by kidney-tonifying and blood-generating granules and Qi-promoting and blood-nourishing granules， respectively， and combined oral androgen and ciclosporin soft capsules. The treatment lasted for six months and was divided into three stages. Visits were conducted from the beginning of the treatment to the end of the first， fourth， and sixth months. The curative effect was evaluated six months later. The total effective rate of the kidney-tonifying and blood-generating group was 86.4% （159/184）， which was significantly better than that of the Qi-promoting and blood-nourishing group ［68.6% （131/191）， P<0.01）］. The results of the percentage quartile of blood cell growth in each stage of the 2 groups were analyzed. The hemoglobin concentration and platelet count of the patients in the kidney-invigorating blood group continued to increase after treatment, and significantly increased in the second and third stages compared with the first stage (P<0.05). The increase of reticulocyte count was most significant in the first stage of treatment (P<0.05). The reticulocyte count in supplementing Qi and nourishing blood group increased significantly in the first and second stages of treatment (P<0.05). The other observation indicators increased at each stage, but there was no statistical difference in the growth rate. The effects of the two groups were compared by stages. In the second stage of treatment, the increase of hemoglobin concentration in the kidney-invigorating blood group was better than that in the supplementing Qi-nourishing blood group (P<0.05). The increase of platelet count and red blood cell count in supplementing Qi and nourishing blood group was greater (P<0.05). In the third stage of treatment, the increase of hemoglobin concentration in the bushen Shengxue group was more significant (P<0.05). ConclusionThe overall effective rate of the kidney-tonifying and blood-generating method in the treatment of aplastic anemia is better than that of the Qi-promoting and blood-nourishing method， with significant effects and safety. This study has proposed a three-stage early treatment mode for aplastic anemia. The first and third stages (0-1, 5-6 months) were mainly treated by invigorating kidney and generating blood. In the second stage of treatment (2-4 months), invigorating kidney and generating blood combined with invigorating Qi and nourishing blood were adopted. It may be closer to the actual clinical treatment response and objective rule changes of aplastic anemia.

Early Efficacy Predictors of Bushen Shengxue Prescription Combined with Western Medicine in Treatment of Aplastic Anemia / 中国实验方剂学杂志

ObjectiveTo investigate the predictive indicators of early efficacy of Bushen Shengxue prescription combined with western medicine in the treatment of aplastic anemia， and provide prognosis indicators for the treatment of aplastic anemia （AA） with kidney-tonifying therapy in traditional Chinese medicine （TCM） combined with western medicine. MethodA total of 126 patients treated by Bushen Shengxue prescription combined with western medicine in 19 hospitals including Xiyuan Hospital of the China Academy of Chinese Medical Sciences from September 2018 to March 2021 were selected for a retrospective study. The therapy was proven to be effective after six months of treatment. According to the efficacy after 4 months of treatment， the patients were assigned into a 4-month effective group and a 4-month ineffective group. The age， sex， disease severity （including severe aplastic anemia and non-severe aplastic anemia）， course of disease， degree of bone marrow nucleated cell proliferation， baseline hemogram levels ［including white blood cell count （WBC）， absolute neutrophil count （ANC）， hemoglobin （HGB）， platelets （PLT）， and reticulocytes （RET）］， T lymphocytes subsets， and the expression levels of T-box transcription factor （T-bet） and GATA-binding protein-3 （GATA-3） were compared between the two groups before treatment. ResultThe proportions of patients within the age ranges of ［20， 40） and ［60， 80） were higher in the 4-month effective group （P<0.05）. The sex， disease severity， course of disease， and comorbidities had no significant differences between the two groups. The 4-month effective group had higher baseline levels of HGB， WBC， ANC， and PLT than the 4-month ineffective group （P<0.05）， and there was no significant difference in the RET level between the two groups before treatment. Binary Logistic regression analysis showed that the PLT level before treatment was an independent factor affecting the onset time， while other indicators did not affect the onset time. The receiver operating characteristic （ROC） curve was established to analyze the value of PLT level before treatment for predicting the onset time， and the area under the curve was 0.691. With the critical value of 40.5×109/L， the sensitivity and specificity of the prediction that the therapy will take effect within 4 months were 0.569 and 0.893， respectively. The two groups of patients were graded according to age ｛（14， 20）， ［20， 40）， ［40， 60）， and ［60， 80）｝ and PLT level before treatment （PLT<40×109/L， PLT≥40×109/L）. The proportion of the patients with PLT≥40×109/L before treatment in the 4-month effective group was significantly higher than that in the 4-month ineffective group （P<0.05）. The degree of bone marrow nucleated cell proliferation before treatment had no significant difference between the two groups. The level of total T lymphocytes in the 4-month effective patients was lower than that in the 4-month ineffective patients before treatment （P<0.05）. The levels of Th1 cells， Th2 cells， CD4+ T cells， and CD8+ T cells showed no significant differences between the two groups before treatment.

Referral criteria of the SPOT Vision Screener for children under 6 years old / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To revise the referral criteria for the SPOT Vision Screener in children under 6 years old and assessed its accuracy based on the American Association for Pediatric Ophthalmology and Strabismus(AAPOS)uniform guidelines for instrument-based pediatric vision screen validation 2021.METHODS: Children who visited the Maternal and Child Health Center of Yuhuatai District in Nanjing city from January 2022 to April 2023 were included in the study and underwent SPOT refractive screening, cycloplegic retinoscopy, and other examinations. Abnormal children were defined according to AAPOS guidelines with amblyopia risk factors(ARFs)and visually significant refractive error(VSRE). Receiver operating characteristic(ROC)curve was used to calculate the optimal referral criteria and compared with manufacturer criteria, Wu's criteria, and Peterseim's criteria.RESULTS: A total of 959 children were examined, with 342 in the &#x003C;4-year-old group and 617 in the ≥4-year-old group. The optimal referral criteria for the &#x003C;4-year-old group were myopia ≤-2.75 D, hyperopia ≥+2.25 D, astigmatism ≤-2.75 D, and anisometropia ≥1.00 D. For the ≥4-year-old group, the criteria were myopia ≤-1.75 D, hyperopia ≥+2.00 D, astigmatism ≤-2.25 D, and anisometropia ≥1.00 D. The Youden index was 0.38 and 0.52, respectively, which were higher than other criteria.CONCLUSION: The use of new referral criteria for refractive screening in children under 6 years old demonstrates higher accuracy compared to previous criteria. It provides valuable guidance for pediatric eye care and vision health in children.

Adverse reactions and precautions of teprotumumab in the treatment of thyroid-associated ophthalmopathy / 国际眼科杂志(Guoji Yanke Zazhi)

Thyroid-associated ophthalmopathy(TAO)is an autoimmune disease associated with thyroid dysfunction that can significantly impact quality of life, result in visual impairment and facial disfigurement. Traditional treatments are often unsatisfactory. Studies have shown that teprotumumab, a human monoclonal antibody that can inhibit insulin-like growth factor 1 receptor(IGF-1R), has become an emerging targeted drug for TAO. Although the drug has proven to be effective and relatively safe in the treatment of TAO, adverse reactions are worthy of attention of ophthalmologists with the continuous promotion of clinical application, including hearing impairment, hyperglycemia, diarrhea, muscle spasms, infusion reactions, cognitive decline, thyroid suppression, alopecia, nausea and fatigue. Teprotumumab was generally well tolerated, with most adverse events being mild or moderate in severity. This paper aims to review the adverse reactions and precautions of teprotumumab in the treatment of TAO.

Analysis of Predictive Factors for Efficacy of Yiqi Yangxue Prescription Combined with Western Medicine in Treatment of Aplastic Anemia in Non-elderly Adults / 中国实验方剂学杂志

ObjectiveTo explore the predictive factors for the efficacy of Yiqi Yangxue prescription combined with western medicine in treating aplastic anemia （AA） in non-elderly adults， so as to provide a reference for predicting the prognosis of this therapy. MethodA retrospective study was conducted with the clinical data of non-elderly adult AA patients who visited 19 hospitals including Xiyuan Hospital of the China Academy of Chinese Medical Sciences from September 2018 to March 2021 and were treated with Yiqi Yangxue Prescription combined with western medicine. According to the efficacy evaluation results at the 6th month of treatment， the patients were assigned into effective and ineffective groups. The two groups were compared in terms of the gender， age， disease classification ［non-severe aplastic anemia （NSAA）/severe aplastic anemia （SAA）］， course of disease， family history， complications， history of drug allergy， baseline blood routine examination ［hemoglobin （HGB）， white blood cell （WBC）， neutrophil （ANC）， platelet （PLT）， and reticulocyte （Ret）］， T lymphocyte subsets， degree of proliferation of nucleated cells in bone marrow， and expression of T-bet and GATA-3. ResultA total of 101 non-elderly adult AA patients were enrolled in this study， including 81 in the effective group and 20 in the ineffective group. The effective group had a higher proportion of the patients without a history of drug allergy than the ineffective group （P<0.05）. The body height， body weight， gender， age， disease classification， course of disease， family history， and complications showed no significant differences between two groups. The effective group had higher levels of ANC and PLT before treatment （P<0.05） and higher proportion of patients with ANC≥1.6×109/L and PLT≥25×109/L （P<0.05， P<0.01） than the ineffective group. The baseline levels of WBC， HGB， and Ret showed no significant statistical differences between two groups. The levels of CD3+HLA-DR+T cells in the effective group before treatment was higher than that in the ineffective group （P<0.05）. The levels of CD3+CD19-T cells， CD4+T cells， CD8+T cells， Th1 cells， Th2 cells， and CD3+CD25+T cells showed no significant statistical differences between two groups before treatment. The proportion of patients with active bone marrow nucleated cells proliferation in the effective group before treatment were significantly higher than that in the ineffective group, while the proportion of patients with reduced or extremely reduced proliferation were significantly lower than that in the ineffective group （P<0.05）. The expression levels of T-bet and GATA-3 genes had no significant differences between two groups before treatment. The multivariate binary logistic regression analysis showed that the ANC level before treatment and history of drug allergy were independent influencing factors for efficacy （P<0.05， P<0.01）， while other indicators were not influencing factors for efficacy. The receiver operating characteristic （ROC） curve was applied to analyze the predictive value of the ANC level before treatment in the treatment of AA in non-elderly adults with Yiqi Yangxue prescription combined with western medicine. The area under the curve was 0.679 （P<0.05）， with the critical value of 1.595×109/L， the sensitivity of 0.42， and the specificity of 0.95. ConclusionThe history of drug allergy， pre-treatment ANC， PLT， CD3+HLA-DR+ T cell levels， and proliferation of nucleated cells in bone marrow before treatment are predictive factors for the efficacy of Yiqi Yangxue prescription combined with western medicine in treating AA in non-elderly adults. This therapy tends to be more effective for the patients with no history of drug allergy， higher ANC and PLT levels before treatment， especially those with ANC≥1.6×109/L， PLT≥25×109/L， and higher CD3+ HLA-DR+T cell levels and the more active proliferation of nucleated cells in bone marrow before treatment.

Treatment of Patients with Mediate-Risk Pure Ground Glass Pulmonary Nodules Based on the State Theory：A Prospective Randomize-controlled Clinical Observation / 中医杂志

ObjectiveTo observe the clinical efficacy and safety of treating mediate-risk pure ground glass pulmonary nodules （pGGNs） based on the state theory. MethodsA prospective clinical randomized controlled trial was used. Totally 141 cases of mediate-risk pGGNs were divided into treatment group （92 cases） and control group （49 cases） according to the random table method. The treatment group was given the basic Sanjie Formula （基础散结方） orally with modification according to the identification of traditional Chinese medicine （TCM） state， 1 dose per day， 3 months as a course of treatment.Three months after the treatment patients were checked by CT. Patients who were clinically judged as cure， moderate to low risk， and turned to surgical resection do not carry out a second course of treatment，and the rest of the patients continued to complete the second courses. Patients in the control group did not receive any treatment and were only followed up periodically. Patients in both groups received a CT review 3 months and 6 months after enrolled. Comprehensive curative effect was evaluated according to the reduction rate of the area of pulmonary nodules shown in chest CT， to further explore the clinical effective difference for patients at different TCM state； the risk of malignancy index （Mayo score） was calculated by Mayo model at enrollment and 3 months and 6 months after enrolled. Adverse events were monitored continuously during the study. ResultsDuring the follow-up， 8 cases in the treatment group and 7 cases in the control group were lost. A total of 126 cases completed the whole process， including 84 cases in the treatment group and 42 cases in the control group. The total effective rates at 3 months and 6 months of the treatment group were 46.15% （30/65） and 45.71% （32/70） in the treatment group， while the total effective rates at 3 months and 6 months in the control group were 12.5% （4/32） and 10.00% （4/40）. Compared with the control group， the comprehensive curative effect of 3 months and 6 months of enrollment in treatment group was significantly better than that in corresponding control group （P＜0.01）. The pulmonary nodule area and Mayo score in the treatment group decreased after 3 and 6 months of enrollment （P＜0.01）. In contrast， there was no statistically significant difference in nodule area between pre- and post-enrollment time points in the control group （P＞0.05）， and probability of Mayo risk increased in the control group after 6 months of enrollment compared to pre-enrollment （P＜0.05）. Among the 84 patients in the treatment group， there were 15 cases of qi deficiency state， 7 cases of yin deficiency state， 5 cases of yang deficiency state， 20 cases of qi depression state， 32 cases of damp-heat state， and 5 cases of harmonious state； the difference in the distribution of the total clinical effective rate of the patients with different TCM states after treatment was statistically significant （P＜0.05）， and the total effective rate of two-by-two comparison of qi depression state was higher （13/20，65.00%） than that of the total effective rate of damp-heat state （8/32，25.00%， P＜0.00833）. There were no significant changes in blood routine， urine routine， liver function and kidney function in both groups， and no adverse events occurred. ConclusionTreating mediate-risk pGGNs based on the state theory can effectively reduce the area of pulmonary nodules and inhibit the growth of malignant risk of pulmonary nodules.

The expression patterns of SMG family members in aortas of patients with Stanford type A aortic dissection / 中华胸心血管外科杂志

Objective:To investigate the relationship between the expression patterns of SMG family members and aortic dissection by comparing the expression levels of SMGs in aortic wall of patients with Stanford type A aortic dissection(AD) and normal controls.Methods:The aortic wall samples were collected from 31 normal controls and 65 patients with Stanford type A aortic dissection. The mRNA levels of SMGs in the aortic wall were quantified by RT-PCR, and the correlations between SMGs and aortic diameters of patients with aortic dissection were analyzed.Results:The results of RT-PCR showed that compared with normal aortic wall, the mRNA levels of SMG3(0.642±0.529 vs. 1.126±0.858, P=0.023), SMG6(0.737±0.652 vs. 1.877±1.902, P=0.005), and SMG7(0.624±0.449 vs. 1.339±0.866, P=0.00067) were obviously increased in aortic wall of patients with aortic dissection, while comparable mRNA levels of SMG1, SMG2, SMG4, SMG5, SMG8 and SMG9 were detected between these two groups. In addition, there was no significant correlation between the expression levels of SMG3, SMG6, SMG7 and aortic diameters. Conclusion:The expression levels of SMG3, SMG6 and SMG7mRNA were significantly increased in patients with aortic dissection, suggesting that they may promote the occurrence of aortic dissection, and targeting SMG family members expected to a novel strategy for the prevention and treatment of aortic dissection.

Clinical features and outcomes of women with epilepsy who withdraw anti-seizure medications in early pregnancy / 中华神经科杂志

Objective:To explore anti-seizure medication (ASM) treatment patterns, seizures, maternal and fetal outcomes and offspring outcomes of pregnant women with epilepsy (PWWE) who withdraw ASM in the first trimester of pregnancy.Methods:A retrospective analysis was performed on the PWWE database registered in West China Hospital, Sichuan University from January 2009 to October 2022. Patients who withdrew ASM therapy in the first trimester and those who maintained ASM therapy throughout pregnancy were included. Withdrawal in the first trimester was defined as discontinuation of ASM between 0 and 3 months of pregnancy. Sixty-five PWWE (withdrawal group) who withdraw ASM in the first trimester were included, and 130 PWWE (maintained-therapy group) who took ASM throughout pregnancy in West China Hospital during the same period were matched 1∶2. Demographic characteristics, ASM, seizures, maternal and fetal outcomes within 1 year were compared between the 2 groups. In the subgroup analysis, the withdrawal group was divided into a full withdrawal group ( n=53) and a resumption group ( n=12) according to whether the ASM was resumed in the second and third trimesters of pregnancy, and the 2 groups were stratified and compared. Results:In the withdrawal group, the proportion of patients with bachelor degree below [72.3% (47/65) vs 54.6% (71/130), χ 2=5.68, P=0.017], family income less than 5 000 yuan per capita [44.6% (29/65) vs 18.5% (24/130), χ 2=14.98, P<0.001], a family history of epilepsy [12.3% (8/65) vs 3.1% (4/130), χ 2=4.90, P=0.027], and a second pregnancy [43.1% (28/65) vs 26.2% (34/130), χ 2=5.72, P=0.017] was higher than in the maintained-therapy group. The proportion of patients who received multiple ASM was lower in the withdrawal group than in the maintained-therapy group [16.9% (11/65) vs 38.5% (50/130), χ 2=9.35, P=0.002]. In the withdrawal group, the rate of seizures with tonic-clonic seizures during pregnancy [50.8% (33/65) vs 31.5% (41/130), χ 2=6.81, P=0.009] and seizure exacerbation during pregnancy [32.3% (21/65) vs 9.2% (12/130), χ 2=16.41, P<0.001] was higher. The preterm birth rate in the withdrawal group was lower than that in the maintained-therapy group [4.6% (3/65) vs 19.2% (25/130), χ 2=101.70, P<0.001]. The rate of seizure exacerbation during pregnancy was higher in the resumption group than in the full withdrawal group [7/12 vs 26.4% (14/53), χ 2=3.22, P=0.073]. Conclusions:PWWE with a family history of epilepsy and a second pregnancy were more likely to withdraw ASM during pregnancy. After withdrawal, the seizures during pregnancy were significantly worse, but the preterm birth rate of offspring was relatively reduced.

Association between the preoperative nocturnal blood pressure pattern and postoperative complications in elderly patients undergoing laparoscopic gastrointestinal surgery / 中华老年医学杂志

Objective:To explore the association between the preoperative nocturnal blood pressure pattern and postoperative complications in elderly patients undergoing laparoscopic gastrointestinal surgery.Methods:A prospective observational cohort study was conducted in 131 elderly patients undergoing elective laparoscopic gastrointestinal surgery under general anesthesia between September 2018 and September 2021.All subjects underwent 24 h ambulatory blood pressure monitoring 1 day before surgery and, based on the nocturnal blood pressure pattern, patients were divided into two groups.Those with the nocturnal blood pressure reduction rate ≥0% entered the nocturnal blood pressure reduction group(Group D, n=80), and those with the reduction rate <0% entered the nocturnal blood pressure increase group(Group R, n=51). Differences in postoperative complication rates between the two groups were compared, and multivariate Logistic regression was used to analyze the influencing factors of postoperative complications.Results:(1)Compared with Group D, the prevalence of diabetes and left ventricular mass index were significantly increased and the mean nighttime SBP and DBP were significantly increased in Group R( P<0.05); (2)Compared with Group D, the incidence of acute kidney injury and acute heart failure in Group R was significantly higher( P<0.05), with the relative risk( RR)values at 2.941(95% CI: 1.344-6.435)and 3.660(95% CI: 0.991-13.512), respectively; (3)Multivariate Logistic regression analysis showed that elevated blood pressure at night was an independent risk factor for acute kidney injury after surgery( OR=3.700, 95% CI: 1.286-10.648, P=0.015); (4)Kaplan-Meier curves for acute kidney injury and acute heart failure showed that the cumulative incidence of events in Group R was significantly higher than that in Group D(Log rank test: P<0.05). Conclusions:For elderly patients undergoing selective laparoscopic gastrointestinal surgery, preoperative nocturnal blood pressure patterns were associated with postoperative complications.Elevated preoperative nocturnal blood pressure increases the incidence of postoperative acute kidney injury and heart failure, and elevated nocturnal blood pressure is an independent risk factor for acute kidney injury.
