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 clinical effect of air moxibustion combined with pushpin-like needle acupuncture,which is formulated based on the"suppressing wood-supporting earth"theory in the doctrine of the five elements of Traditional Chinese Medicine(TCM),in the treatment of pain,nausea and vomiting after transcatheter arterial chemoembolization(TACE).Methods A total of 160 patients with hepatocellular carcinoma,who were admitted to the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine of China to receive initial TACE between July 2020 and June 2023,were enrolled in this study.The patients were randomly divided into 4 groups with 40 patients in each group.The patients of the control group received TACE with conventional nursing care,the patients of the pushpin-like needle group received pushpin-like needle acupuncture on the basis of the control group,the patients of the air moxibustion group received air moxibustion treatment on the basis of the control group,and the patients of the combination group received air moxibustion combined with pushpin-like needle acupuncture on the basis of the control group.The post-TACE pain degree(VAS scoring)and nausea/vomiting extent(INVR scoring)were compared between each other among the four groups.Results The differences in the VAS score and INVR score(including main effect and interaction effect)between each other among the four groups were statistically significant(all P＜0.05).Statistically significant differences in the VAS score and INVR score existed between the control group and the other three groups(all P＜0.05).The differences in the VAS score and INVR score between combination group and pushpin-like needle group,as well as between combination group and air moxibustion group were statistically significant(both P＜0.05).Conclusion Air moxibustion combined with pushpin-like needle acupuncture can effectively and remarkably relieve post-TACE pain,nausea and vomiting,which is superior to simple use of air moxibustion or pushpin-like needle acupuncture.Therefor,the combination use of air moxibustion and pushpin-like needle acupuncture should be popularized in clinical practice.

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 changes in the nutritional status of pediatric patients after allogeneic hematopoietic stem cell transplantation(allo-HSCT)for one year,and to analyze the risk factors.Methods:We collected data from 88 pediatric patients who underwent allo-HSCT at the Department of Hematology and Oncology in Children's Hospital of Nanjing Medical University between May 2018 and November 2022.All pediatric patients underwent nutritional status analysis before transplantation,at enrollment,3 months,6 months and 1 year after allo-HSCT.Linear regression model was used to analyze the risk factors for growth rate.Results:The body mass index Z score(BMI-Z)before allo-HSCT was(0.096±1.349),and decreased to(-0.258±1.438)、(-0.715±1.432)、(-0.584±1.444)at enrollment,3 months,6 months after allo-HSCT,and(-0.130±1.317)at 1 year after allo-HSCT(P<0.001).There was no significant change in BMI-Z between pre-transplantation and 1 year after transplantation(P=1.000).Height for age Z score(HAZ)before transplantation was(0.137±1.305)and decreased to(-0.083±1.267)、(-0.221±1.299)、(-0.269±1.282)in 3 months,6 months and 1 year after allo-HSCT(P<0.001).Multivariate linear regression showed that age≥10 years old(P=0.015)and chronic graft-versus-host disease(cGVHD)(P=0.005)were independent risk factors for change in HAZ.Conclusion:The BMI-Z of pediatric patients treated with allo-HSCT returned to the pre-transplantation level after one year,while HAZ continued to decrease.Allo-HSCT may cause impaired growth rate in pediatric patients.Attention should be paid to HAZ changes in pediatric patients before and after allo-HSCT,especially in pediatric patients≥10 years old of age and those with cGVHD.Effective nutritional intervention should be provided in time.

A portable multi-wavelength spectral detector was developed for on-site,rapid and accurate detection of organic pollutants in surface water using ultraviolet light-emitting diodes(UV-LEDs)and the corresponding spectral detection method was built.By measuring the fluorescence spectrum and absorption light intensity and combining with the multi-wavelength spectral correlation calculation method to analyze the target,the developed detector was able to qualitatively and quantitatively detect organic pollutants that responded in the UV-light range of 260-370 nm.The proposed detector was used to detect polycyclic aromatic hydrocarbons(PAHs)and Rhodamine B.The linear ranges of anthracene and Rhodamine B in absorption mode were 10-100 and 8.5-100 mg/L,respectively.In fluorescence mode,the linear ranges for anthracene and Rhodamine B were 0.006-50 and 0.02-0.781 mg/L,correspondingly.The absorption/fluorescence concurrent mode could extend the detection ranges of anthracene and Rhodamine B to 0.006-100 and 0.02-100 mg/L,respectively.The recoveries of PAHs in surface water ranged from 97.4%to 105.1%for anthracene and 84.5%to 91.2%for anthracene,naphthalene,and pyrene in absorption and fluorescence modes,respectively.The method was accurate in both modes.The mixtures containing PAHs were identified by the proposed method under the optimized multi-wavelength spectral correlation calculation.The results demonstrated that the method could achieve a similarity of 75%or more when identifying two different concentrations of solutions containing a single or a mixture of targets within the linear concentration range of the targets.However,the similarity dropped to less than 25%when identifying two solutions of different substances.The proposed method had excellent recognition abilityof targets.The proposed detector and method combined fluorescence and absorption spectroscopy,which could expand the application of spectroscopy in the in situ rapid identification and detection of pollutants such as PAHs in surface water.

Objective: This study compared the outcomes of laparotomic radical hysterectomy (LRH) and minimally invasive radical hysterectomy (MISRH) in patients with early-stage cervical cancer. Methods: The clinical data of patients with early-stage cervical cancer who underwent LRH or MISRH (laparoscopic/robotic) at Chang Gung Memorial Hospital, Linkou Branch, from 2002 to 2017 were retrospectively reviewed. The surgical safety (operation time, blood loss, blood transfusion rate, length of postoperative stay, and perioperative complications), overall survival (OS), disease-free survival (DFS), and recurrence pattern were analyzed. Propensity score matching (PSM) at a 3:1 ratio was performed to balance prognostic variables. Results: Of the 760 patients (entire cohort), 614 underwent LRH and 146 underwent MISRH.After PSM, 394 and 140 patients were included in the LRH and MISRH groups, respectively.The 5-year OS rate was significantly lower in the MISRH group than in the LRH group (85.6% vs. 93.2%, p=0.043), and the 5-year DFS rate (p=0.21) did not differ significantly. After PSM, the 5-year OS rates did not differ significantly between the MISRH and LRH groups (87.1% vs. 92.1%, p=0.393). The MISRH group had a significantly shorter operation time (p<0.001), lower intraoperative blood loss (p<0.001), lower blood transfusion rate (p<0.001), and shorter postoperative stay (p<0.001) but a significantly higher rate of intraoperative bladder injury (p<0.001) than the LRH group. Conclusion After PSM, MISRH is associated with nonsignificantly lower OS but a significantly higher risk of intraoperative urological complications than LRH.

Objective To evaluate the efficacy and safety of tacrolimus extended-release (Tac-ER) in the early stage after kidney transplantation. Methods Clinical data of 68 recipients undergoing kidney transplantation from 34 pairs of renal allografts were retrospectively analyzed. Two recipients who received bilateral kidneys from the same donor were treated with Tac-ER (Tac-ER group) and tacrolimus immediate-release (Tac-IR) (Tac-IR group) as one of the basic immunosuppressant. The changes of tacrolimus dosage and blood concentration, intra-patient variability (IPV), renal function, incidence of acute rejection, recipient and allograft survival rates and adverse events were statistically compared between two groups. Results The average daily dose of tacrolimus in the Tac-ER group was significantly higher than that in the Tac-IR group (F=8.386, P=0.005). In the Tac-ER group, the mean trough concentration at postoperative 4 d was (6.14±4.04) ng/mL, did not reach the target concentration, significantly lower than (9.41±5.47) ng/mL in the Tac-IR group (F=7.854, P=0.007). In the Tac-ER group, the IPV of trough concentration of tacrolimus within postoperative 1 month was significantly higher than that in the Tac-IR group (0.44±0.15 vs. 0.36±0.12, P=0.032). At postoperative 6 months, there was no significant difference in the renal function between two groups [serum creatinine level was (126±26) μmol/L vs. (120±28) μmol/L, and the estimated glomerular filtration rate was (56±13) mL/(min·1.73 m²) vs. (60±15) mL/(min·1.73 m²), both P > 0.05]. The allograft and recipient survival rates were 100% in both groups. The incidence of acute rejection within postoperative 1 month was 18% in the Tac-ER group and 3% in the Tac-IR group, with no significant difference (P > 0.05). The overall incidence of adverse events was 94% in the Tac-ER group and 97% in the Tac-IR group, with no significant difference (P > 0.05). Conclusions The efficacy and safety of Tac-ER are equivalent to those of Tac-IR, whereas a higher dose of Tac-ER should be orally given to reach the blood concentration similar to that of Tac-IR. During early-stage drug treatment, Tac-ER should be orally given before kidney transplantation or inittally with loading dose, aiming to increase the systemic exposure to tacrolimus early after kidney transplantation and prevent acute rejection caused by insufficient exposure.
