[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

BACKGROUND:microRNA-26b(miR-26b)plays an important regulatory role in a variety of stem cell functions,but its effects on the biological properties of stem cells from human exfoliated deciduous teeth and human umbilical cord mesenchymal stem cells are unknown. OBJECTIVE:To investigate the effects of miR-26b on the proliferation,migration and osteogenic differentiation of stem cells from human exfoliated deciduous teeth and human umbilical cord mesenchymal stem cells. METHODS:Stem cells from human exfoliated deciduous teeth and human umbilical cord mesenchymal stem cells were cultured and identified.miR-26 mimics(experimental group)and miRNAs mimics control(control group)were used to transfect above mentioned two kinds of cells and construct overexpressed models for subsequent experiments.CCK-8 assay was applied to detect the proliferation ability of overexpressed miR-26b cells.Transwell and scratch assay were employed to analyze the migration ability of overexpressed miR-26b cells.RT-qPCR was utilized to examine the expression of osteogenic markers after osteogenic induction of overexpressed miR-26b cells. RESULTS AND CONCLUSION:(1)Transfection of miR-26b mimics increased miR-26b expression in the two kinds of cells and promoted the proliferation of stem cells from human exfoliated deciduous teeth,with no significant effect on the amplification of human umbilical cord mesenchymal stem cells.(2)Compared with the control group,the migration ability was enhanced after two types of cells overexpressing miR-26b.(3)miR-26b expression decreased during osteogenic differentiation of the two kinds of cells.(4)Compared with the control group,the levels of osteogenesis-related genes osteocalcin,osteopontin,alkaline phosphatase,and human type I collagen mRNA were downregulated after overexpression of miR-26b in the two kinds of cells.The results showed that overexpression of miR-26b promoted the proliferation and migration of stem cells from human exfoliated deciduous teeth and inhibited their osteogenic differentiation;it promoted the migration of human umbilical cord mesenchymal stem cells and inhibited their osteogenic differentiation,but had no significant effects on their proliferation.

Malocclusion,identified by the World Health Organization(WHO)as one of three major oral diseases,profoundly impacts the dental-maxillofacial functions,facial esthetics,and long-term development of～260 million children in China.Beyond its physical manifestations,malocclusion also significantly influences the psycho-social well-being of these children.Timely intervention in malocclusion can foster an environment conducive to dental-maxillofacial development and substantially decrease the incidence of malocclusion or reduce the severity and complexity of malocclusion in the permanent dentition,by mitigating the negative impact of abnormal environmental influences on the growth.Early orthodontic treatment encompasses accurate identification and treatment of dental and maxillofacial morphological and functional abnormalities during various stages of dental-maxillofacial development,ranging from fetal stages to the early permanent dentition phase.From an economic and societal standpoint,the urgency for effective early orthodontic treatments for malocclusions in childhood cannot be overstated,underlining its profound practical and social importance.This consensus paper discusses the characteristics and the detrimental effects of malocclusion in children,emphasizing critical need for early treatment.It elaborates on corresponding core principles and fundamental approaches in early orthodontics,proposing comprehensive guidance for preventive and interceptive orthodontic treatment,serving as a reference for clinicians engaged in early orthodontic treatment.

Brucella are a group of small gram-negative bacteria that infect the human body through various transmission routes. They can travel with the blood to various organs and tissues throughout the body, causing bacteremia, toxemia, sepsis, and local infections. Brucellosis is relatively rare in developed countries and more common in developing countries. Although the typical symptoms of brucellosis are easy to identify, some manifestations are not well-known, such as eye involvement in brucellosis patients. Eye inflammation is usually a late manifestation, and Brucella can cause different symptoms in the eyes, leading to misdiagnosis or missed diagnosis. Therefore, it should be considered in differential diagnosis. To further enhance the understanding of eye involvement in patients with brucellosis among healthcare workers, this article provides a review of its pathogenesis, clinical manifestations, auxiliary examinations, diagnosis, and treatment characteristics.

Objective:To understand the status and related factors of emotional inhibition among women re-ceiving in vitro fertilization-embryo transfer(IVF-ET).Methods:A total of 791 women receiving IVF-ET from a specialized hospital in Changsha were selected,and surveyed with the General Questionnaire,Emotional Inhibition Scale(EIS),Locke-Wollance Marital Adjustment Questionnaire,Self-Compassion Scale and Medical Coping Mode Questionnaire.Results:The average score of EIS in women receiving IVF-ET was(28.0±6.4).Multiple linear re-gression analysis showed that the EIS scores in women receiving IVF-ET were negatively associated with infertility factors(β=-9.23,-4.56,-2.86),personality type(β=-1.11),and marital adjustment,confrontation and self-compassion scores(β=-0.03,-0.13,-0.05),and positively associated with residence and surrender di-mension scores(β=0.82,0.20).Conclusion:It suggests that women receiving IVF-ET have a certain degree of e-motional inhibition,which is related to infertility factors,residence,personality type,self-compassion,marital adjust-ment,confrontation,and surrender.

Objective:To investigate the expression level of long non-coding RNA (lncRNA) CTC-338M12.4 in tongue squamous cell carcinoma tissues, and its effects on the cell cycle, cell proliferation, and migration of tongue squamous cell carcinoma cells in vitro as well as its molecular mechanisms.Methods:The Gene Expression Omnibus (GEO) database was used to obtain the lncRNA series data set GSE139869, and the differential expression of CTC-338M12.4 in tongue squamous cell carcinoma tissues and adjacent tissues was analyzed. The transcriptional expression levels of CTC-338M12.4 in human immortalized oral keratinocytes (HOK) and tongue squamous cell carcinoma cell lines HN13, TSCCa, CAL-27, Tca8113, SCC15 were detected by using reverse transcription quantitative real-time polymerase chain reaction (qRT-PCR). CAL-27 cells with the lowest expression level of CTC-338M12.4 were selected and were divided into the control group (co-transfected with vectors containing negative sequence) and CTC-338M12.4 group (co-transfected with CTC-338M12.4 overexpression vectors). The proliferation ability of CAL-27 cells in each group was detected by using cell colony formation assay, and the cell cycle distribution of CAL-27 cells was detected by using flow cytometry. The migration ability of CAL-27 cells was detected by using scratch test. The lncACTdb database was used to predict the complementary binding sites between CTC-338M12.4 and miRNA-27a-5p (miR-27a-5p), and dual-luciferase reporter gene assay was used to verify. The expression level of miR-27a-5p in CAL-27 cells of all groups was detected by using qRT-PCR. The protein expression level of related factors on JAK/STAT signaling pathway in CAL-27 cells of all groups was detected by using Western blot.Results:Analysis of GEO database data showed that transcriptional level CTC-338M12.4 in tongue squamous cell carcinoma tissues was lower than that in adjacent tissues, and the difference was statistically significant ( P < 0.01). Transcriptional level CTC-338M12.4 in tongue squamous cell carcinoma HNl3, TSCCa, CAL-27, Tca8113, and SCC15 cells was lower than that in HOK cells, and the differences were statistically significant (all P < 0.05). The transcriptional level relative expression level of CTC-338M12.4 in CAL-27 cells in the CTC-338M12.4 group was higher than that in the control group, and the difference was statistically significant ( P < 0.01). Cell colony formation assay showed that the colong number of CAL-27 cell in the CTC-338M12.4 group was less than that in the control group [(51±10) vs. (114±21)], and the difference was statistically significant ( t = 2.71, P = 0.035). Flow cytometry showed that the proportion of G 0/G 1 phase cells in CAL-27 cells in the CTC-338M12.4 group was higher than that in the control group [(64±3)% vs. (43±4)%], and the difference was statistically significant ( t = 4.87, P = 0.003). The scratch test showed that when scratching, the scratch width of both groups was similar ( P > 0.05); after scratch for 25 h, the scratch width of CAL-27 cells in the CTC-338M12.4 group was wider than that in the control group [(133±15) μm vs. (64±10) μm], and the difference was statistically significant ( t = 3.78, P = 0.009). The dual luciferase reporter gene assay showed that the relative luciferase activity of CAL-27 cells co-transfected with wild-type CTC-338M12.4 sequence and miR-27a-5p sequence was lower than that of CAL-27 cells co-transfected with wild-type CTC-338M12.4 sequence and miR-27a-5p irrelevant sequence, and the difference was statistically significant ( P < 0.001). The relative expression level of transcriptional level miR-27a-5p of CAL-27 cells in the CTC-338M12.4 group was lower than that in the control group, and the difference was statistically significant ( P = 0.003). Western blot showed that the protein expression levels of JAK/STAT signaling pathway p-JAK, p-STAT, p-Raf, p-ERK, and p-mTOR were lower than those in the control group. Conclusions:The level of lncRNA CTC-338M12.4 is low in tongue squamous cell carcinoma. CTC-338M12.4 mediates the inactivation of JAK/STAT signaling pathway via inhibiting miR-27a-5p expression in tongue squamous cell carcinoma CAL-27 cells, thereby leading to cell cycle arrest and inhibiting the cell proliferation and migration of CAL-27 cells.

OBJECTIVE: To explore the genetic basis for a Chinese pedigree affected with hereditary spastic paraplegia type 30 (HSP30). METHODS: A proband presented at the Second Hospital of Shanxi Medical University in August 2021 was selected as the study subject. The proband was subjected to whole exome sequencing, and candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The proband was found to have harbored a heterozygous c.110T>C variant in exon 3 of the KIF1A gene, which can cause substitution of isoleucine by threonine at position 37 (p.I37T) and alter the function of its protein product. The same variant was not found in his parents, elder brother and elder sister, suggesting that it has a de novo origin. Based on the guidelines of the American College of Medical Genetics and Genomics (ACMG), the variant was rated as likely pathogenic (PM2_Supporting+PP3+PS2). CONCLUSION The c.110T>C variant of the KIF1A gene probably underlay the HSP30 in the proband. Above finding has enable genetic counseling for this family.

Objective:To explore the application of list nursing management combined with different artificial liver treatment modes in patients with liver failure.Methods:Fifty-three patients with liver failure hospitalized in Bethune Hospital of Shanxi Province from July 2020 to July 2021 were selected as the control group, 63 patients with liver failure hospitalized in Bethune Hospital of Shanxi Province from July 2021 to July 2022 were selected as the intervention group. According to the different treatment modes of artificial liver for patients, plasma exchange (PE), double plasma molecular adsorption system (DPMAS) and PE + DPMAS treatment were set up in the two groups. The control group received routine nursing care, while the intervention group received checklist nursing care in addition. The changes of albumin (ALB) and prothrombin time (PT) indexes before and after the different treatment modes were compared, together with the occurrence of complications between the two groups after the intervention.Results:The baseline data between the two groups was balanced, the difference had no statistical significant ( P>0.05). After the therapy, the level of ALB of patients who had accepted DPMAS and PE + DPMAS in the intervention group were 25.3(24.0, 27.9) and 23.2(22.4, 26.3) g/L, which were lower than the 28.2(26.3, 29.7) and 29.4(27.2, 30.0) g/L in the control group, the differences were significant ( Z = 2.47, 3.55, both P<0.05). After the therapy, the level of PT of patients in the intervention group under all three treatment modes were 15.8(14.8, 16.8), 22.7(19.2, 26.2) and 6.0(14.6, 20.0) s, which were lower than the 17.4(15.9, 20.9), 26.3(21.4, 36.4) and 21.2(16.9, 23.4) s in the control group, the differences were significant ( Z = 2.10, 2.07, 2.21, all P<0.05). In the intervention group, there were 6 cases of hypotension, anaphylaxis, bleeding, coagulation and infection under the DPMAS treatment mode, which was significant lower than the 11 cases in the control group ( χ2 = 4.97, P<0.05). There were 4 cases in the intervention group with the PE + DPMAS treatment mode occurred complications in above, which were significant lower than the 11 cases in the control group ( χ2 = 6.87, P<0.01). Conclusions:Artificial liver treatment can improve patients′ liver function and coagulation, and list nursing management may help to improve the effect of artificial liver treatment. It can improve nurses′ awareness of risk prejudgement, reduce various risks in the treatment process, reduce the incidence of adverse reactions, and enhance health care and patient satisfaction.
