Aim To screen and study the expression of long non-coding RNA (IncRNA) in rats with middle cerebral artery occlusion (MCAO) with MCAO treated with Tao Hong Si Wu decoction (THSWD) and determine the possible molecular mechanism of THSWD in treating MCAO rats. Methods Three cerebral hemisphere tissue were obtained from the control group, MCAO group and MCAO + THSWD group. RNA sequencing technology was used to identify IncRNA gene expression in the three groups. THSWD-regulated IncRNA genes were identified, and then a THSWD-regu-lated IncRNA-mRNA network was constructed. MCODE plug-in units were used to identify the modules of IncRNA-mRNA networks. Gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) were used to analyze the enriched biological functions and signaling pathways. Cis- and trans-regulatory genes for THSWD-regulated IncRNAs were identified. Reverse transcription real-time quantitative pol-ymerase chain reaction (RT-qPCR) was used to verify IncRNAs. Molecular docking was used to identify IncRNA-mRNA network targets and pathway-associated proteins. Results In MCAO rats, THSWD regulated a total of 302 IncRNAs. Bioinformatics analysis suggested that some core IncRNAs might play an important role in the treatment of MCAO rats with THSWD, and we further found that THSWD might also treat MCAO rats through multiple pathways such as IncRNA-mRNA network and network-enriched complement and coagulation cascades. The results of molecular docking showed that the active compounds gallic acid and a-mygdalin of THSWD had a certain binding ability to protein targets. Conclusions THSWD can protect the brain injury of MCAO rats through IncRNA, which may provide new insights for the treatment of ischemic stroke with THSWD.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Calcified lesions increase the difficulty of interventional therapy for coronary heart disease,and increase the risk of perioperative and long-term complications.Pretreatment of calcified lesions is very important.Coronary lithotripsy(IVL)is used more and more in calcified lesions,and many clinical trials have proved its effectiveness and safety.Stent underexpansion is an important risk factor for stent thrombosis and restenosis,which increases the incidence of complications.At present,there is no effective coping strategy or clear consensus or guidelines for the treatment of stent underexpansion caused by calcified lesions.There are few reports about the treatment of stent under expansion by IVL,and most of them are case reports and small sample studies.In this paper,two cases of stent under expansion were reported.After stent implantation,stent under expansion was found,and IVL was used to treat the cases,which achieved good results.This paper reports 2 cases of stent under expansion to explore the efficacy and safety of IVL in the treatment of such lesions.

Objectives:To analyze the early clinical efficacy of modified percutaneous transforaminal lumbar interbody fusion(MPTLIF)in the treatment of lumbar degenerative diseases.Methods:The clinical data of 26 patients who underwent MPTLIF at the Second Affiliated Hospital of Army Medical University between Jan-uary 2020 and October 2021 were analyzed retrospectively.There were 12 males and 14 females,aged 44-77 years(58.3±8.4 years);Lumbar spondylolisthesis in 16 cases,lumbar spinal instability with radicular stenosis in 10 cases;3 cases were of L3/4 and 23 cases were of L4/5.The operative time,intraoperative bleeding,post-operative hospital stay,and postoperative drainage were analyzed.The visual analogue scale(VAS)for pain was documented before operation,at 3d and 3 months after operation and at the final follow-up,the Oswestry disability index(ODI)was used for evaluation before operation,at 3 months and the final follow-up after oper-ation,and the modified MacNab efficacy evaluation criteria were used to evaluate the clinical efficacy at the final follow-up.The anteroposterior height of the intervertebral space,lumbar lordosis angle,and lordosis an-gle of the operated segment were measured on X-ray and CT images before surgery and at the final follow-up.Results:All the patients successfully underwent the operation with an operative time of 98.9±6.6min,in-traoperative bleeding of 41.0±12.6mL,postoperative drainage of 38.1±9.5mL,and an average postoperative hos-pital stay of 3.8±0.9d without complications such as epidural hematoma,infection,or muscle paralysis and paralysis.The follow-up time was 17.7±4.2 months,and the VAS scores preoperatively,3d postoperatively,3 months postoperatively,and at final follow-up were 5.85±0.67,2.15±0.54,1.12±0.33,0.54±0.51,respectively.The ODI were(47.38±6.66)％,(11.73±6.73)％,and(6.58±6.51)％before operation,at 3 months and the final follow-up,respectively.The VAS scores and ODI at all time points after operation significantly improved compared with the preoperative values(P＜0.05),and which improved over time(P＜0.05).At final follow-up,ac-cording to the modified MacNab criteria,24 cases were evaluated as excellent and 2 cases were evaluated as good.The anteroposterior height of the intervertebral space(anterior edge 10.95±1.24mm,posterior edge 9.45± 1.13mm),lumbar lordosis(47.38°±4.56°)and lordosis angle of the operated segment(8.62°±1.92°)were higher at final follow-up than before operation(anterior edge 8.85±1.00mm,posterior edge 6.78±1.07mm,43.81°±4.85°,6.62°±2.02°),with significant improvement(P＜0.05).Conclusions:MPTLIF is a safe and effective minimally invasive procedure for the treatment of lumbar degenerative disease in cases selected for strict indications,which can achieve great early clinical efficacy.

Aim To screen and study the effects of Tao Hong Si Wu decoction(THSWD)-mediated treat-ment on circular RNA(circRNA)expression profiles in rats with middle cerebral artery occlusion(MCAO),and investigate the possible roles and molecular mecha-nisms of THSWD.Methods Next-generation RNA sequencing was conducted to identify circRNA expres-sion profiles in MCAO rats after treatment with THSWD and compared with the MCAO model group and control group.Bioinformatics analysis was performed to predict the potential target microRNAs and mRNAs.Gene On-tology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses for the potential target mRNAs were applied to explore the potential roles of differentially expressed circRNAs.RT-qPCR was performed to verify circRNAs with significant differences in expression.Results We identified 87 significantly differentially expressed circRNAs between the MCAO group versus the control group,and 86 sig-nificantly differentially expressed circRNAs between the MCAO group versus the THSWD group.respective-ly.Among them,17 circRNAs induced by the MCAO model were reversed via treatment with THSWD.To demonstrate the roles of mRNAs targeted by DECs,the GO and KEGG databases were used.Further analysis revealed that five circRNAs may play important roles in the development of MCAO.Conclusions The com-prehensive expression profile of circRNAs in rats with middle cerebral artery occlusion after THSWD treat-ment is determined for the first time,suggesting that the therapeutic effect of THSWD on MCAO may be a-chieved by regulating the expression of circRNAs.

OBJECTIVE: To observe the effect of preoperative, intraoperative and postoperative electroacupuncture (EA) intervention on postoperative urination function in patients with mixed hemorrhoid surgery. METHODS: A total of 240 patients with mixed hemorrhoid surgery under lumbar anesthesia were randomly divided into an EA preconditioning group (group A, 60 cases, 9 cases dropped off), an intraoperative EA group (group B, 60 cases, 4 cases dropped off), a postoperative EA group (group C, 60 cases, 6 cases dropped off), and a non-acupuncture group (group D, 60 cases, 3 cases dropped off). In the groups A, B and C, EA was exerted at Zhongliao (BL 33) and Huiyang (BL 35) , with disperse-dense wave, 4 Hz/20 Hz in frequency, and lasting 30 min, at 30 min before lumbar anesthesia, immediately after lumbar anesthesia and 6 h after surgery, respectively. No EA intervention was performed in the group D. The postoperative urination smoothness score in each group was observed 24 h after surgery. The first urination time, first urination volume, urine residual volume after first urination were recorded, and incidence of indwelling catheterization, postoperative visual analogue scale (VAS) score, number of remedial analgesia, and the incidence of postoperative nausea and vomiting were observed in each group. RESULTS: In the groups A, B and C, the postoperative urination smoothness scores were superior to the group D (P<0.05), and the time of first urination was earlier than the group D (P<0.05). In the group C, the time of first urination was earlier than the group A and the group B (P<0.05), the first urination volume was higher than the group D (P<0.05), and the urine residual volume after first urination was lower than the group D (P<0.05). There was no significant difference in the incidence of indwelling catheterization and postoperative nausea and vomiting among the 4 groups (P>0.05). The VAS scores of the group A, B and C were lower than that in the group D (P<0.05), and the number of remedial analgesia cases was lower than that in the group D (P<0.05). CONCLUSION EA intervention could promote the recovery of urination function and relieve postoperative pain in patients with mixed hemorrhoids surgery. Early postoperative EA intervention is more conducive to the recovery of urination function.

Objective: To analyze the clinical and molecular diagnostic status of Fanconi anemia (FA) in China. Methods: The General situation, clinical manifestations and chromosome breakage test and genetic test results of 107 pediatric FA cases registered in the Chinese Blood and Marrow Transplantation Registry Group (CBMTRG) and the Chinese Children Blood and Marrow Transplantation Registry Group (CCBMTRG) from August 2009 to January 2022 were analyzed retrospectively. Children with FANCA gene variants were divided into mild and severe groups based on the type of variant, and Wilcoxon-test was used to compare the phenotypic differences between groups. Results: Of the 176 registered FA patients, 69 (39.2%) cases were excluded due to lack of definitive genetic diagnosis results, and the remaining 107 children from 15 hospitals were included in the study, including 70 males and 37 females. The age at transplantation treatment were 6 (4, 9) years. The enrolled children were involved in 10 pathogenic genes, including 89 cases of FANCA gene, 7 cases of FANCG gene, 3 cases of FANCB gene, 2 cases of FANCE gene and 1 case each of FANCC, FANCD1, FANCD2, FANCF, FANCJ, and FANCN gene. Compound heterozygous or homozygous of loss-of-function variants account for 69.2% (72/104). Loss-of-function variants account for 79.2% (141/178) in FANCA gene variants, and 20.8% (37/178) were large exon deletions. Fifty-five children (51.4%) had chromosome breakage test records, with a positive rate of 81.8% (45/55). There were 172 congenital malformations in 80 children.Café-au-Lait spots (16.3%, 28/172), thumb deformities (16.3%,28/172), polydactyly (13.9%, 24/172), and short stature (12.2%, 21/172) were the most common congenital malformations in Chinese children with FA. No significant difference was found in the number of congenital malformations between children with severe (50 cases) and mild FANCA variants (26 cases) (Z=-1.33, P=0.185). Conclusions: FANCA gene is the main pathogenic gene in children with FA, where the detection of its exon deletion should be strengthened clinically. There were no phenotypic differences among children with different types of FANCA variants. Chromosome break test is helpful to determine the pathogenicity of variants, but its accuracy needs to be improved.
