Gastroparesis is a gastric disease characterized by delayed gastric emptying."Vomiting"is the main clinical manifestation of this disease,while"atrophy"indicates dysfunction of the stomach.Based on the theory of"atrophy,dyspnea and vomiting are ascribed to the upper part",originating from the Chapter of"Zhi Zhen Yao Da Lun"from the Suwen(Basic Questions)section this paper explored the pathogenesis and treatment idea of gastroparesis from the function of the lung.It is put forward that failure of lung qi in dispersion,so the lung qi cannot maintain the circulation of harmonizing qi and blood,leading to malnutrition of stomach and loss of stomach receiving food and drink function.Melancholy impairing lung,so lung cannot govern diffusion,leading to stomach governing the disfunction of dredging and descending.Impaired depurative descending of lung qi,so the large intestine and stomach are lost in the alternating operation of deficiency and excess,leading to stomach governing the disfunction of transportation and transformation.Therefore,the treatment approach is proposed to improve the stomach's function to receive food and drink,transport and transform and promote the recovery of gastric motility by replenishing and restoring lung qi,regulating emotions and catharsis and smoothing lung.Analyzing the effect of function of the lung on gastric motility is of great value for expanding the application of traditional Chinese medicine in gastrointestinal motility disorders,and digging new connotations of classic theories in modern clinical practice.

Objective:To explore the acupoint selection law of acupuncture and moxibustion in treating diabetic gastroparesis (DGP) using data mining technology.Methods:The clinical literature on acupuncture and moxibustion treatment for DGP was retrieved from CNKI, Wanfang Data, VIP, SinoMed, PubMed, the Cochrane Library from the establishment of the databases to July 31, 2023. The acupoint prescriptions were extracted to Excel 2016 to establish a database, and the statistics of acupoint frequency, meridian, distribution site and specific acupoint use were collected. SPSS Modeler 18.0 was used to analyze the association rules among acupoints, and SPSS Statistics 25.0 was used for clustering analysis and factor analysis to summarize the acupoint selection law for acupuncture treatment of DGP.Results:Totally 153 articles were included, involving 59 acupoints, with a total frequency of 802 times. The 5 most frequently used acupoints were "Zusanli" (ST 36), "Zhongwan" (CV 12), "Neiguan" (PC 6), "Sanyinjiao" (SP 6), "Pishu" (BL 20). The commonly used meridians were stomach meridian, Conception Vessel and bladder meridian. The involved acupoints were mostly located in the chest-abdomen and lower limbs, and most of them were Wushu acupoints, Mu acupoints, and Xiahe acupoints. The core acupoints group was "Zusanli (ST 36)-Zhongwan (CV 12)-Neiguan (PC 6)-Pishu (BL 20)-Weishu (BL 21)-Sanyinjiao (SP 6)-Tianshu (ST 25)", 24 groups of association rules, 5 effective clusters and 6 factors were obtained.Conclusion:Acupuncture and moxibustion treatment of DGP focuses on both spleen and stomach, treating both symptoms and root causes, and uses methods of combining acupoints such as distant and near matching, combining Mu acupoints, and Xiahe acupoints, and combining of Wushu acupoints and Mu acupoints, to achieve the therapeutic effect of nourishing yin and tonifying qi, dispelling upper abdominal fullness and resolving turbidity, and harmonizing stomach and strengthening spleen.

Objective:To investigate the clinical application effect of enhanced recovery after surgery(ERAS) in the perioperative period of primary repair for children with hypospadias.Methods:Non-randomized controlled study.Retrospective analysis was made on clinical data of 206 children with hypospadias admitted to the Department of Urology, Shanxi Children′s Hospital from March 2018 to March 2022.According to whether the concept of ERAS was adopted for perioperative management of children, they were divided into the ERAS group(109 cases) and the non-ERAS group(97 cases). t-test and Chi-square test were used to analyze the differences between the two groups of patients in hospitalization days, hospitalization costs, pain scores on the first day after surgery, average number of bowel movements within 5 days after surgery, first out-of-bed activity time, hospital satisfaction score, and complication rate. Results:Pediatric patients in the ERAS group showed better outcomes compared to the non-ERAS group: shorter hospital stays[(7.71±1.12) d vs.(21.00±1.07) d], lower hospitalization costs[(10 043.21±1 341.00) yuan vs.(12 993.44±1 081.00) yuan], lower postoperative pain scores on the first day[(5.21±1.32) points vs.(6.09±1.07) points], more frequent bowel movements within 5 days[(5.16±0.65) times vs.(2.91±0.48) times], earlier time to first out-of-bed activity[(5.03±0.61) d vs.(7.12±0.57) d], and higher hospital satisfaction scores[(4.71±0.21) points vs.(4.14±0.15) points], and the differences were statistically significant(all P<0.05).Additionally, the ERAS group had lower rates of fever(6.42%, 7/109) and constipation(3.67%, 4/109) before urinary catheter removal compared to the non-ERAS group[21.64%(21/97) and 28.87%(28/97), respectively](all P<0.05).There were no significant differences in the incidences of complications such as urethral prolapse, infection, delayed wound healing, and bleeding, as well as urethral stricture, urethral fistula, and urethral diverticulum after urinary catheter removal between the two groups(all P>0.05). Conclusions:ERAS protocol applied in the perioperative period of primary repair for children with hypospadias can shorten the hospitalization time, lower the hospitalization costs, and accelerate the rehabilitation of children.It is worth further promotion.

Abstract: Objective To express Mycobacterium tuberculosis Rv2626c protein in Escherichia coli (E. coli) and study the antigenicity of the purified recombinant Rv2626c protein. Methods The amino acid sequence of Rv2626c protein from Mycobacterium tuberculosis H37Rv strain (accession number: CCP45424.1) in GenBank was retrieved and converted into the corresponding DNA sequence according to the codon preference of E. coli. This DNA sequence was synthesized and cloned into pET24a(+) plasmid to construct pET24a(+)-Rv2626c recombinant plasmid. This plasmid was transformed into E. coli BL21(DE3) cells, and the expression of Rv2626c protein was induced under various conditions of isopropyl β-D-thiogalactopyranoside (IPTG) concentrations, temperature, and period. The recombinant Rv2626c protein was identified by SDS-PAGE and Western Blot. The recombinant Rv2626c protein was purified by nickel chelate affinity chromatography and used to immunize violet blue rabbits to prepare anti-Rv2626c anti-serum. The specificity and titer of the serum were respectively detected by Western Blot and enzyme-linked immunosorbent assay (ELISA). Results The recombinant plasmid pET24a(+)-Rv2626c was successfully constructed. SDS-PAGE analysis showed that recombinant Rv2626c was expressed in the recombinant plasmid transformed E. coli with IPTG induction, with a molecular weight of about 14 500, and the size was consistent with the expectation. The optimal expression condition for recombinant Rv2626c protein was at 31 ℃ with 1.0 mmol/L IPTG for 6 hours. The target protein was mainly present in a soluble form, which was consistent with the results of Western blot. The hyperimmunized serum with recombinant Rv2626c protein vaccination showed good specificity, with a titer of 1∶ 256 000 detected by ELISA. Conclusions Mycobacterium tuberculosis Rv2626c protein is successfully expressed in E. coli, and the purified protein has good purity and antigenic activity, laying the foundation for further reveals of its biological functions.

OBJECTIVE: To review the research progress in biotherapy of rotator cuff injury in recent years, in order to provide help for clinical decision-making of rotator cuff injury treatment. METHODS: The literature related to biotherapy of rotator cuff injury at home and abroad in recent years was widely reviewed, and the mechanism and efficacy of biotherapy for rotator cuff injury were summarized from the aspects of platelet-rich plasma (PRP), growth factors, stem cells, and exosomes. RESULTS: In order to relieve patients' pain, improve upper limb function, and improve quality of life, the treatment of rotator cuff injury experienced an important change from conservative treatment to open surgery to arthroscopic rotator cuff repair. Arthroscopic rotator cuff repair plus a variety of biotherapy methods have become the mainstream of clinical treatment. All kinds of biotherapy methods have ideal mid- and long-term effectiveness in the repair of rotator cuff injury. The biotherapy method to promote the healing of rotator cuff injury is controversial and needs to be further studied. CONCLUSION All kinds of biotherapy methods show a good effect on the repair of rotator cuff injury. It will be an important research direction to further develop new biotherapy technology and verify its effectiveness.

Long non-coding RNAs (lncRNAs) which are usually thought to have no protein coding ability, are widely involved in cell proliferation, signal transduction and other biological activities. However, recent studies have suggested that short open reading frames (sORFs) of some lncRNAs can encode small functional peptides (micropeptides). These micropeptides appear to play important roles in calcium homeostasis, embryonic development and tumorigenesis, suggesting their potential as therapeutic targets and diagnostic biomarkers. Currently, bioinformatic tools as well as experimental methods such as ribosome mapping and in vitro translation are applied to predict the coding potential of lncRNAs. Furthermore, mass spectrometry, specific antibodies and epitope tags are used for validating the expression of micropeptides. Here, we review the physiological and pathological functions of recently identified micropeptides as well as research strategies for predicting the coding potential of lncRNAs to facilitate the further research of lncRNA encoded micropeptides.

Lipophagy, the selective engulfment of lipid droplets (LDs) by autophagosomes for lysosomal degradation, is critical to lipid and energy homeostasis. Here we show that the lipid transfer protein ORP8 is located on LDs and mediates the encapsulation of LDs by autophagosomal membranes. This function of ORP8 is independent of its lipid transporter activity and is achieved through direct interaction with phagophore-anchored LC3/GABARAPs. Upon lipophagy induction, ORP8 has increased localization on LDs and is phosphorylated by AMPK, thereby enhancing its affinity for LC3/GABARAPs. Deletion of ORP8 or interruption of ORP8-LC3/GABARAP interaction results in accumulation of LDs and increased intracellular triglyceride. Overexpression of ORP8 alleviates LD and triglyceride deposition in the liver of ob/ob mice, and Osbpl8-/- mice exhibit liver lipid clearance defects. Our results suggest that ORP8 is a lipophagy receptor that plays a key role in cellular lipid metabolism.

Objective: This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder. Methods: Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration. Results: The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week. Conclusion PMTS is safe and effective in improving insomnia disorders.

Objective:To explore the differences of renal dynamic imaging parameters between operation group and non-operation group in infants with severe hydronephrosis, so as to accumulate theoretical basis for diuretic renal scintigraphy to help the treatment decision making.Methods:A total of 107 infants (age: 3(2, 6) months; 90 males and 17 females) with severe hydronephrosis, who underwent diuretic renal scintigraphy between March 2018 and October 2021 in Shanxi Children′s Hospital were retrospectively reviewed. All patients were diagnosed with ureteropelvic junction obstruction and divided into operation group ( n=87) and no-operation group ( n=20). The differences of differential renal function (DRF), peak time, half-time and drainage curve between the two groups were compared with the independent-sample t test or χ2 test, and the correlation between the renal function of the affected side and the anteroposterior pelvic diameter (APD) was analyzed with Pearson correlation analysis. Results:The operation group included 17 patients with DRF<40%, 60 patients with DRF between 40%-55%, and 10 patients with DRF>55%(supernormal renal function). The 40%-55% was considered as normal DBF, and the rest were abnormal. Infants with abnormal renal function in the operation group ( n=27) were more than those in the non-operation group ( n=3), but there was no statistical difference ( χ2=2.07, P=0.150). The proportion of obstruction curve in the operation group (85.1%, 74/87) was significantly higher than that in the non-operation group (55.0%, 11/20; χ2=7.24, P=0.007). Compared with the non-operation group, the peak time of affected kidney in the operation group was significantly longer ((22.77±7.52) vs (15.26±10.29) min; t=3.78, P<0.001), as well as the peak time of contralateral kidney ((11.25±8.47) vs (6.65±5.75) min; t=2.30, P=0.023). There was a negative correlation between the DRF of the affected side and the APD ( r=-0.48, P<0.001). Conclusions:The DBF is mostly in the normal range in infants with severe hydronephrosis, and supernormal renal function is common. The previous operation indication (DRF<40%) is not suitable for the infants, and it needs to be analyzed combined with the type of curve and the APD determined by color Doppler ultrasound. The prolongation of contralateral renal peak time may be an important parameter for the surgical evaluation of severe hydronephrosis in infants.

Tbx18,Wt1,and Tcf21 have been identified as epicardial markers during the early embryonic stage.However,the gene markers of mature epicardial cells remain unclear.Single-cell transcriptomic analysis was performed with the Seurat,Monocle,and CellphoneDB packages in R software with standard pro-cedures.Spatial transcriptomics was performed on chilled Visium Tissue Optimization Slides(10x Genomics)and Visium Spatial Gene Expression Slides(10x Genomics).Spatial transcriptomics analysis was performed with Space Ranger software and R software.Immunofluorescence,whole-mount RNA in situ hybridization and X-gal staining were performed to validate the analysis results.Spatial transcriptomics analysis revealed distinct transcriptional profiles and functions between epicardial tissue and non-epicardial tissue.Several gene markers specific to postnatal epicardial tissue were identified,including Msln,C3,Efemp1,and Upk3b.Single-cell transcriptomic analysis revealed that cardiac cells from wildtype mouse hearts(from embryonic day 9.5 to postnatal day 9)could be categorized into six major cell types,which included epicardial cells.Throughout epicardial development,Wt1,Tbx18,and Upk3b were consistently expressed,whereas genes including Msln,C3,and Efemp1 exhibited increased expression during the mature stages of development.Pseudotime analysis further revealed two epicardial cell fates during maturation.Moreover,Upk3b,Msln,Efemp1,and C3 positive epicardial cells were enriched in extracellular matrix signaling.Our results suggested Upk3b,Efemp1,Msln,C3,and other genes were mature epicardium markers.Extracellular matrix signaling was found to play a critical role in the mature epicardium,thus suggesting potential therapeutic targets for heart regeneration in future clinical practice.
