OBJECTIVEThis research aimed to investigate the expression of osteoprotegerin (OPG) and receptor activator of nuclear factor-κB ligand (RANKL) in mandibular distraction osteogenesis (DO) regulated by parathyroid hormone (PTH) and to explore the mechanism by which PTH promotes DO.

METHODSA rabbit mandibular DO model was established. The rabbits were randomly divided into experimental group and control group. The former were subcutaneously injected with different doses of PTH on alternate days, the latter was injected with normal saline every other day. Serum OPG levels were detected through enzyme-linked immunosorbent assay. The OPG and RANKL expression levels in the DO-induced formation of a new bone tissue were examined through immunohistochemistry staining.

RESULTSThe serum OPG levels gradually increased during distraction. At the end of the stretch, the OPG expression in the experimental group was significantly stronger than that in the control group. As the fixed period was extended, the OPG expression in the new bone gradually decreased, but the RANKL expression increased.

CONCLUSIONIntermittent subcutaneous PTH injection can upregulate the OPG expression and accelerate bone metabolism. Thus, this procedure promotes the early generation of a new bone in the mandible through DO.

Objective:To analyze the specific reasons for journal articles being retracted due to biomedical research-related ethical issues after publication and propose corresponding preventive measures.Methods:Journal articles that were retracted between January 1, 2021, and January 1, 2023, were retrieved from PubMed, a literature database in the biomedical field. The retraction statements of those articles that were retracted due to ethical-related issues were analyzed with a summarization of detailed reasons and types.Results:A total of 77 and 128 articles were retracted due to ethical issues in 2021 and 2022 respectively, accounting for 3.9% and 5.4% of all retracted articles in the same period. The major ethical issue was the lack of valid ethical approval. Among articles retracted for ethical issues related to human trials, the proportion of articles retracted due to lack of valid ethical approval increased from 45.9% in 2021 to 57.0% in 2022, which also increased from 50.0% in 2021 to 67.3% in 2022 among retracted articles related to animal experiments. Other ethical issues included problems in the informed consent process, delay in obtaining ethical approval, inconsistency between ethical approvals and the content of the article, and violation of the principles of laboratory animal welfare.Conclusions:The ethical review of medical research involving humans and laboratory animal welfare needs to be strengthened. By promoting the construction of an institutional ethical review system, encouraging researchers to study ethics-related knowledge, standardizing ethical applications and approvals, improving the informed consent process, and attaching importance to the welfare of laboratory animals, the retraction due to ethical issues can be prevented.

Acupuncture at Baliao points for urinary incontinence has the advantages of obvious therapeutic effect, simple operation and few complications, which is mainly used for the treatment of urinary incontinence after stroke, urinary incontinence after spinal cord injury, stress urinary incontinence and urinary incontinence of bladder overactivity, etc. Urinary incontinence after stroke and spinal cord injury is a complication of disease, most of which are combined with acupuncture at Baliao points on the basis of primary disease treatment. The bladder meridian of foot-Taiyang has the characteristics of "entering the collateral brain" and "carrying spine to the waist". Baliao points can conduct induction along the bladder meridian to the sick site along the bladder meridian, and can play a certain therapeutic role in the treatment of the primary disease. Stress urinary incontinence and urinary incontinence of bladder overactivity can be regarded as independent diseases. Since Baliao points are located in the lumbosacral region which is close to the bladder, acupuncture can play a role in the near treatment of acupoints, improve the operation of bladder qi and blood, and the curative effect has a cumulative effect.

OBJECTIVE: To study the genetic variants of a child with Autism Spectrum Disorder (ASD) combined with epilepsy, and explore its possible pathogenic mechanism. METHODS: Clinical data of the child were collected and evaluated, whole-exome sequencing (WES) technology was used to explore the genetic variants sites of the child and his parents and candidate genes were filtered out. Sanger sequencing were performed to verify the variants identified by WES and PolyPhen2 was utilized to predict the function of these variants. qPCR was carry out to determine the expression of the variant gene. RESULTS: The proband carried a compound heterozygous mutation in the SIK3 gene (Chr11 q23.3, NM_025164.6), which contains a missense mutation c.1295A>G (p.N432S) inherited from the father and a deletion [c.2389_2391del(p.797del)] inherited from the mother. Both mutation sites are highly conservative, and PolyPhen2 predicted (c.1295A>G [p.N432S]) to be harmful. Compared to the mother, expression of SIK3in mRNA level in the peripheral blood of the proband and his father were both significantly decreased; compared to normal child, SIK3 expression in the peripheral blood of the proband and two other children with ASD were all decreased significantly too. In addition, studies on mice found that Sik3 gene has a marked higher level of expression in the brain. CONCLUSION The SIK3 gene variants may probably be associated with ASD. The detailed mechanism needs to be studied further, which may involve lipid metabolism dysfunction in the brain.

Objective:To investigate the efficacy and safety of internet-based cognitive behavioral therapy for insomnia(iCBT-I) combined with estazolam for patients with chronic insomnia.Methods:Patients with chronic insomnia were randomly assigned to treatment group which were intervened with iCBFI combined with estazolam( n=46) and control group which were intervened with estazolam ( n=43) for 8 weeks according to random number table.Pittsburgh sleep quality index (PSQI) and state-trait anxiety inventory (STAI) were used to measure the anxious state, anxious trait and sleep quality at three time points: before intervention(T1), after one month(T2) and two months(T3). Treatment emergent symptom scale (TESS), blood routine, urine routine, liver and renal function and electrocardiogram were used to measure the safety.The dosage of estazolam was compared between the two groups after two months.χ 2 test and repeated measurement analysis of variance were performed by SPSS 19.0. Results:The PSQI scores of control group and treatment group were (10.41±2.48) vs (9.98±2.96) at T2 and (9.97±2.13) vs (7.82±1.57) at T3.The state anxiety scores of control group and treatment group were (57.27±2.74) vs (56.27±2.89) at T2 and (45.67±2.62) vs (42.67±2.97) at T3.The data of T2 and T3 were statistically significant compared with those before intervention(all P<0.05). Compared with the control group, the treatment group was better on treatment efficiency(86.96% vs 69.77%) at T3( P<0.05). PSQI score, subjective sleep quality, sleep efficiency, sleep disorders, sleep drugs, daytime dysfunction, drug maintenance and adverse reaction were significantly different between the two groups at T3 ( P<0.05). Conclusions:Internet-based cognitive behavioral therapy combined estazolam for insomnia can improve sleep quality, anxious state and trait for chronic insomnia patients.Good safety was improved, as well as reducing the need of drug.So it's worthy of clinic application.

Objective To explore the folate receptor alpha(FRA)expression in different types and stages of in endometrial carcinoma(EC). The sensitivity and specificity of FRA testing were compared with CA125 to evaluate its diagnostic performance.Methods Serum from 50 cases of EC patients and 30 cases of normal patients was collected.Tissue from 83 cases of typeⅠEC and 30 cases of normal endometrium and typeⅡEC were collected. The expression of serum FRA was detected by ELISA.The expression ofserum CA125 was detected by electrochemi-luminescence.The expression of FRA and CA125 in tissues was detected by immunohistochemistry. Results The rate of elevated FRA expression of in typeⅠEC tissue was higher than that in typeⅡEC(P < 0.05). The rate of elevated FRA expression in type I EC was higher than that in the early stage(P < 0.05). The ROC curve showed that the sensitivity and specificity of FRA was higher than these of CA125′s. Further,they are higher in the com-bined serum FRA and CA125.Conclusions This study shows that the FRA expression level in endometrial carci-noma varies in different subtypes,indicating the potential different pathogeneses. The rate of elevated FRA expression in type I endometrial carcinoma was higher than that in the early stage. This provides the possibility for the application of FRA targeted fluorescent developer in advanced endometrial carcinoma meticulous surgery. Combination of FRA and CA125 have better diagnostic value in detecting EC.
