Objective To explore the predictive value of heel blood thyrotropin stimulating hormone(TSH)and insulin-like growth factor-1(IGF-1)for congenital hypothyroidism(CH).Methods A total of 83 children with CH admitted to the Seventh Medical Center of the Chinese People's Liberation Army General Hospital from January 2021 to January 2024 were selected as the study group,and 53 healthy newborns born and examined in the center during the same period were selected as the control group.Heel blood TSH,IGF-1 and thyroid function were measured in both groups.Heel blood TSH,IGF-1 and thyroid function indexes were compared between the two groups,and the correlation between heel blood TSH,IGF-1 and thyroid function indexes was analyzed,the influencing factors of CH occurrence were analyzed,and the predictive value of heel blood TSH,IGF-1 and thyroid indexes for CH was analyzed.Results Pearson correlation analysis showed that heel blood TSH was negatively correlated with FT4,TT3,FT3 and TT4(r=-0.522,-0.468,-0.539,-0.667,all P＜0.05).IGF-1 was positively correlated with FT4,TT3,FT3,TT4(r=0.394,0.427,0.511,0.562,all P＜0.05).The results of receiver operating characteristic curve analysis showed that the area under the curve of TSH,IGF-1 and their combination were 0.800,0.794 and 0.822,respectively.Univariate and multiple Logistic regression analysis showed that birth weight,family history,TSH,IGF-1,FT4,FT3 were the influencing factors for the occurrence of CH(P＜0.05).Conclusion The combined detection of TSH and IGF-1 levels in heel blood has a certain predictive value for the occurrence of CH,and can provide a basis for the disease assessment of children.

Objective:To analyze mortality risk factors in patients with severe pneumonia and investigate their varying influences across different time periods.Methods:A total of 134 patients with severe pneumonia admitted to the Emergency Department of Xiang’an Hospital, Xiamen University, between June 2019 and February 2020 were enrolled. All patients were treated in the EICU and followed up for four years. Based on outcomes, they were categorized into a death group ( n=77) and a survival group ( n=57). COX regression analysis was employed to identify mortality risk factors at different time points, while logistic regression analysis was used to assess risk factors influencing mortality during hospitalization, ICU stay, 1-month, and 1-year follow-up periods. Results:Mortality rates were 11.9% ( n=16) during ICU admission, 20.8% ( n=28) during hospitalization, 16.4% ( n=22) within 1 month, and 31.3% ( n=42) within 1 year. By the end of the follow-up, 57.4% ( n=77) of patients had died. Ten mortality risk factors were identified, with the number increasing over time. During ICU admission and hospitalization, significant risk factors included total bilirubin levels, APACHE-II score, invasive ventilation, ARDS, and vasopressor use in the ICU. One-month mortality risk additionally involved bacterial infection. One-year mortality risk further incorporated advanced age and chronic heart failure. By the end of follow-up, acute kidney injury (AKI) during ICU admission also emerged as a contributing factor, while higher body weight was identified as a protective factor. Conclusions:The number of mortality risk factors in severe pneumonia patients increases progressively over time. Early-stage factors during hospitalization and ICU admission exert a stronger impact on short-term mortality, whereas bacterial infection, advanced age, and chronic heart failure become increasingly significant in later stages. These findings highlight the dynamic nature of risk factors and underscore the importance of tailored monitoring and intervention strategies at different disease phases.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Thyroid cancer (TC) is the most common endocrine malignancy. Although most patients have a favorable prognosis following standardized treatment,a subset experiences rapid disease progression and poor outcomes. Recent studies have identified N6-methyladenosine (m6A) methylation as the most prevalent RNA modification,which regulates RNA transcription,maturation,degradation,and stability,playing a role throughout the tumorigenesis process. Consequently,m6A methylation has been extensively studied in tumor treatment and prevention. Changes in m6A levels can lead to abnormal activation or inhibition of oncogenes or tumor suppressor genes in TC,thereby contributing to its initiation and progression. This review summarizes the concept of m6A methylation,the components and functions of its regulatory factors,its role in the development and progression of TC,and its implications for treatment and prognosis.

To explore the relationship between progesterone receptor (PGR) gene G1978T polymorphism and endometrial carcinoma. METHODS: After searching PubMed, EMBASE, Wan-fang and CNKI databases for literatures on PGR G1978T genotyping of endometrial cancer patients, the data were extracted and odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using STATA15. The whole blood samples of endometrial carcinoma cases (EC group) and normal women (control group) were collected. Allelic-specific primers matching G1978T wild type G allele and mutant type T allele were designed with 3' terminal phosphorothioate modification, and the two-directional primer extension was performed using Exo + polymerase to genotype PGR gene G1978T polymorphism and Sanger sequencing was used to verify the genotype. RESULTS: PGR gene G1978T mutation was marginally associated with endometrial carcinoma risk (ORper allele =1.10, 95%CI=0.98-1.24, P= 0.072). At the same time, only 1 normal blood samples were found with PGR gene G1978T mutation, and the differences in genotypes and allele frequency between the case group and the control group were not statistically significantP>0.05. CONCLUSION: The G1978T polymorphism of the PGR gene maybe not be associated with the risk of endometrial carcinoma.

Objective:To explore the effect of miR-7 on the formation of abdominal aortic aneurysm by up-regulating the expression of ERK and MMP-9 proteins.Methods:Download the miRNAs expression profile chip data from the GEO database, the differentially expressed miRNAs were screened out by GEO2R and the correlation between target genes and ERK genes was analyzed; twenty 4-week male C57BL/6J mice with SPF grade were selected and randomly divided into a model group (only 0.6% BAPN solution was given, n=10) and miR-7 group (fed with 0.6% BAPN solution+ injected with 1×10 9 PFU/ml lentivirus containing miR-7 over expression gene via tail vein, n=10), after 7 weeks of continuous feeding, the mice were anesthetized intraperitoneally with chloral hydrate. After the abdominal cavity and thorax were dissected, the abdominal aorta was separated from the left ventricle perfusion with normal saline under physiological pressure and pathological sections were prepared. Masson staining and α-SMA staining were used to evaluate the lesion degree of abdominal aortic vessels in each group; the protein expression levels of p-ERK1/2 and MMP-9 in the diseased abdominal aorta of each group were detected by WB. Results:By screening differential genes, we found that miR-7 was highly expressed in patients with abdominal aortic aneurysm, and further analysis revealed that miR-7 was positively correlated with ERK1/2; Masson staining showed that the tumor of abdominal aortic aneurysm in miR -7 group was significantly larger than that in the model group, and the difference was statistically significant ( P<0.05), the results of α-SMA histochemical staining showed that the number of α-SMA positive VSMC in miR-7 group was significantly lower than that in the model group, and there was almost no-SMA staining in some VSMC; WB results showed that the highest expressions of P-ERK1/2 and MMP-9 proteins in the abdominal aorta of miR-7 group were significantly higher than that of the model group, with statistically significant differences ( P<0.05). Conclusion:MiR-7 accelerated the formation of abdominal aortic aneurysms by up-regulating the expression of ERK and MMP-9 proteins.

PURPOSE: At this time, there is uncertainty regarding whether allergen avoidance is the most appropriate strategy for managing or preventing allergies. The purpose of this study was to evaluate the effectiveness of allergen avoidance in the prevention of allergic symptoms in previously sensitized patients and newborns that have the potential to develop allergies. METHODS: We performed online searches of articles published from January 1980 to December 2012 in PubMed and The Cochrane Central Register of Controlled Trials, and selected articles involving randomized controlled trials (RCTs) and allergen avoidance. The parameters used to determine allergenic potential in newborns included the risk ratio (RR) of eczema, asthma, rhinitis, wheeze, and cough. The methods employed to evaluate previously sensitized patients were the standardized mean difference (SMD) of forced expiratory volume in 1 second (FEV1) and peak expiratory flow rate (PEFR). Data quality was assessed using the Jadad scale. RESULTS: A total of 14 RCTs were identified. Meta-analysis demonstrated that allergen avoidance for newborns did not reduce the subsequent incidence of allergic diseases (eczema, P=0.21; rhinitis, P=0.3; cough, P=0.1) but significantly reduced the incidence of asthma and wheezing in high-risk infants (asthma, P=0.03; wheeze, P=0.0004). However, previously sensitized patients who reduced their exposure to known allergens did not show improvement in their lung functions (FEV1, P=0.3; PEFR morning, P=0.53; PEFR evening, P=0.2; PEFR, P=0.29). CONCLUSIONS: Allergen avoidance may not always be successful in preventing allergic symptoms. However, rigorous methodological studies are required to confirm this hypothesis.

BACKGROUND:Operation is an important measure to improve the function of spinal cord and to stop the pathological progress of multilevel cervical spondylotic myelopathy. There are controversies how to select the optimum operation mode, to reduce postoperative complications and to elevate clinical curative effects.
OBJECTIVE:To systematical y review patients’ profiles of multilevel cervical spondylotic myelopathy, and to evaluate the effects of simple anterior approach, simple posterior approach and one stage posterior anterior combined approach on cervical spinal curvature index and functional recovery in patients.
METHOD148 sample profiles of patients, who received multilevel cervical spondylotic myelopathy operation in The Affiliated Hospital of Qingdao University and Qingdao Municipal Hospital from February 2000 to February 2008, and met the inclusion and exclusion criteria, were selected. They were divided into simple anterior approach group, simple posterior approach group and one stage posterior anterior combined approach group. The differences in the functional recovery were assessed after treatment using different therapeutic methods.
RESULTS AND CONCLUSION:Cervical spinal curvature index was highest in the simple posterior approach group before treatment (P<0.01). Cervical spinal curvature index was highest in the one stage posterior anterior combined approach group after treatment (P<0.01). Changes in cervical spinal curvature index were most obvious in the simple anterior approach group before and after treatment (P<0.01). No significant difference in Japanese Orthopaedic Association Scores was detected among three groups after treatment (P>0.05).
Significant differences in improvement rate of Japanese Orthopaedic Association Scores were detectable after treatment between the one stage posterior anterior combined approach group and simple anterior approach and simple posterior approach groups (P<0.001). Significant differences in cervical dysfunction index and SF-36 scores were detectable among the three groups before and after treatment (P<0.05). Results indicated that compared with the simple anterior approach and simple posterior approach, decompression through one stage posterior anterior combined approach is a reliable and effective operative procedure for treatment of multilevel cervical spondylotic myelopathy.

OBJECTIVETo elucidate the role of let-7d in regulating the biological behavior of ovarian cancer cells and their expressions of HMGA2 and ras proteins.

METHODSThe pre-let-7d sequence was synthesized and inserted into pcDNA6.2GW/EmGFPmiR and transfected into ovarian cancer IGROV1 cells to cause pre-let-7d overexpression. Real-time quantitative RT-PCR was employed to examine the expression levels of let-7d miRNA and HMGA2 mRNA, and Western blotting was performed to detect the expressions of HMGA2 and ras protein in the transfected cells. The effect of pcDNA6.2GW-let-7d transfection on IGROV1 cell proliferation was determined using MTT assay and the cell apoptosis rate was measured using flow cytometry.

RESULTSThe eukaryotic expression vector containing the target gene let-7d was successfully constructed and transfected into IGROV1 cells. The transfected cells showed a marked reduction of HMGA2 expression but a less obvious down-regulation of ras expression. Transfection with pcDNA6.2GW-let-7d to suppress the expression of HMGA2 caused alterations of the phenotype of IGROV1 cells shown by a reduced proliferative activity and increased cell apoptosis.

CONCLUSIONLet-7d plays an important role in altering the malignant cell phenotype of ovarian cancer IGROV1 cells by regulating the expression of HMGA2.
