Objective:To explore the risk factors and protective factors for esophageal cancer, and provide strategies for prevention, clinical treatment and later-stage intervention.Methods:A total of 150 patients with pathologically confirmed esophageal cancer admitted to Nanjing Liuhe District People′s Hospital from July 2020 to February 2023 were selected as the observation group, and 150 non-tumor patients hospitalized in the department of orthopedics during the same period were selected as the control group. A questionnaire survey was conducted to analyze the independent risk factors and independent protective factors for esophageal cancer.Results:Univariate Logistic regression analysis showed that smoking, alcohol consumption, drinking hot tea (hot drinking >65 ℃), eating hard food, frequency of consuming pickled food, frequency of consuming fruits, frequency of consuming vegetables, frequency of getting angry, economic income and frequency of consuming bread were factors affecting the incidence of esophageal cancer ( P<0.05). Multivariate Logistic regression analysis showed that smoking, consuming fruits ≤3 times per week, previously drinking alcohol but currently not drinking, and not eating hard food were factors affecting the incidence of esophageal cancer ( P<0.05). Conclusions:Smoking and consuming fruits ≤3 times per week are independent risk factors for esophageal cancer, while previously drinking alcohol but currently not drinking and not eating hard food are independent protective factors for esophageal cancer.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To investigate the occurrence of carotid artery abnormalities in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients and the related risk factors affecting the occurrence of carotid artery abnormalities.Methods:A total of 169 regular follow-up outpatients with HIV/AIDS from April 2003 to December 2019 in Peking Union Medical College Hospital, whose carotid artery ultrasound examination were performed from July 2015 to December 2019 were included. The patients were divided into young (≤44 years old), middle-aged and elderly (≥45 years old) according to their ages, and the physical examination data of the included patients were collected.The statistical methods were logistic regression analysis and single sample t test. Results:Among the 169 HIV/AIDS patients, 40(23.7%) had abnormal carotid artery and 129(76.3%) had no abnormal carotid artery. Middle-aged and elderly people (odds ratio ( OR)=3.85, 95%confidence interval (95% CI) 1.54-9.65, P<0.01), hypertension ( OR=6.24, 95% CI 1.95-20.00, P<0.01), hyperlipidemia ( OR=2.44, 95% CI 1.00-5.93, P<0.05), and elevated human leucocyte antigen (HLA)-DR + CD8 + /CD8 + ( OR=1.03, 95% CI 1.01-1.06, P<0.05) were the risk factors for carotid artery abnormality. The common carotid artery inner medium film thickness (IMT) of patients in HIV/AIDS group Ⅰ (20 to 30 years old), group Ⅱ (31 to 40 years old), group Ⅲ (41 to 50 years old) were (0.061 0±0.001 2), (0.062 9±0.001 4) and (0.065 6±0.002 6) cm, respectively, which were thicker than the control groups ((0.051±0.003), (0.056±0.004) and (0.063±0.002) cm, respectively). The differences were all statistically significant ( t=5.119, 4.775 and 1.739, respectively, all P<0.05). The common carotid artery IMT of patients in HIV/AIDS group A (30 to 44 years old) and group B (45 to 59 years old) were (0.062 6±0.001 1) and (0.072 3±0.003 4) cm, respectively, which were thicker than the control groups ((0.052±0.011) and (0.064±0.015) cm, respectively), the differences were both statistically significant ( t=9.520 and 3.012, respectively, both P<0.01). Conclusion:Younger HIV-positive people have a higher probability of abnormal carotid arteries and may be at greater risk of cardiovascular disease than HIV-negative people of the same age, suggesting that HIV-positive people, especially young people, should be examined early with ultrasound of the neck arteries to detect abnormalities and intervene as soon as possible.

Objective:To investigate the expressions of glutathione S-transferases M1 (GSTM1) and glutathione S-transferases M2 (GSTM2) in follicular thyroid carcinoma (FTC) and their clinical significances.Methods:Gene expression profile of GSE82208 generated from 52 human thyroid samples, including 27 cases of FTC and 25 cases of follicular adenoma (FA) were collected from Gene Expression Omnibus (GEO) database. The gene matrix data were extracted and analyzed, and then differentially expressed genes (DEG) between FTC and FA were identified by using Limma package. Immunohistochemical SABC method was used to detect the expression levels of GSTM1 and GSTM2 proteins in FTC tissues and FA tissues collected from 56 FTC samples and 56 FA samples in Dandong First Hospital of Liaoning Province from January 2000 to December 2020. The relationship between GSTM1 and GSTM2 was analyzed; the association of expression levels of GSTM1 and GSTM2 with the clinicopathological factors of FTC patients was also analyzed.Results:Based on the GEO database, a total of 40 DEG were identified, including 9 up-regulated DEG (GSTM1, GSTM2, COL6A2, CUX2, CLUH, TSC2, OGDHL, ACADVL, SDHA) and 31 down-regulated DEG in FTC. The immunohistochemistry results of samples resected showed that the positive rates of GSTM1 and GSTM2 proteins in FTC tissues were higher than those in FA tissues [71.4% (40/56) vs. 23.2% (13/56), 80.4% (45/56) vs. 14.3% (8/56)], and differences were statistically significant ( χ2 values were 26.11 and 49.03, both P < 0.01). The expressions of GSTM1 and GSTM2 in FTC tissues were correlated with clinical staging, invasion degree and distant metastasis (all P < 0.05), but not with gender, age and tumor diameter (all P>0.05). There was a positive correlation between GSTM1 and GSTM2 proteins expressions in FTC ( r = 0.384, P = 0.004). Conclusions:The expression levels of GSTM1 and GSTM2 in FTC are increased. The interaction between GSTM1 and GSTM2 proteins can be involved in the development and progression of FTC.

A 60-year-old male patient with lung cancer received IV infusions of toripalimab 200 mg, bevacizumab 500 mg, and pemetrexed 1 g (the treatment was given on day 1 and 21 days was a cycle) due to the progression of tumor after 26 months of first-line and second-line chemotherapy successively. His thyroid function was normal before treatment. After the second medication of toripalimab (on day 30 after the first medication), the patient developed symptoms such as increased heart rate, fear of heat, hyperhidrosis, and weight loss. The reexamination of thyroid function showed triiodothyronine (T 3) 3.4 nmol/L, thyroxine (T 4) 305.0 nmol/L, free triiodothyronine (FT 3) 13.1 pmol/L, free thyroxine (FT 4) 55.7 pmol/L, thyroid stimulating hormone (TSH) 0.02 mU/L, thyroglobulin (Tg) 32.7 μg/L, antithyroglobulin antibody (TgAb) 531.0 kU/L, antithyroid peroxidase antibody (TPOAb) 318.0 kU/L, and thyroid stimulating hormone receptor antibody (TRAb) 1.00 U/L. Hyperthyroidism was considered, anti-tumor treatment was suspended, and symptoms were improved after metoprolol treatment. Ninety-seven days after the first toripalimab treatment, the patient developed symptoms such as chills, dizziness, fatigue, eyelid edema, weight gain, etc. The laboratory tests showed T 3 0.3 nmol/L, T 4 20 nmol/L, FT 3 1.0 pmol/L, FT 4 1.8 pmol/L, TSH>100.00 mU/L, and carcinoembryonic antigen 251 μg/L. Hypothyroidism was considered, but the tumor progressed, so the treatment of toripalimab was restarted and thyroxine was supplemented at the same time. The patient′s thyroid function was gradually improved and then remained normal. More than 13 months after the first medication of toripalimab, the laboratory tests showed T 3 1.3 nmol/L, T 4 137.0 nmol/L, FT 3 3.8 pmol/L, FT 4 21.1 pmol/L, TSH 6.03 mU/L, Tg 3.9 μg/L, TgAb 432.0 kU/L, and TPOAb 222.0 kU/L.

Objective:To analyze whether the application of growth hormone (GH) in the frozen-thawed embryo transfer (FET) cycle can improve the pregnancy outcome of patients.Methods:The retrospective cohort study including 1042 FET cycles was carried out between January 2015 to July 2018 in Reproductive Medicine Center,the Fourth Hospital of Hebei Medical University. According to medication before transfer, all patients were divided into GH group (group A ) and no GH group (group B). The pregnancy outcomes were compared between the two groups in aged patients (≥35 years), polycystic ovary syndrome (PCOS) patients and repeated implantation failure (RIF) patients.Results:In group A, the maternal age [(31.1±4.5) years old] and the clinical pregnancy rate [67.1% (114/170)] were higher than those in group B [(30.1±4.4) years old, 57.5% (501/872)]( P=0.010, P=0.020). There were no significant differences in the implantation rate, the clinical pregnancy rate, the abortion rate and the live birth rate between group A and group B in aged patients (all P>0.05). In PCOS patients, the live birth rate in group A [65.8% (25/38)] was significantly higher than that in group B [42.3% (96/227)] ( P=0.007). In the RIF patients, the implantation rate [37.3% (57/153)], the clinical pregnancy rate [50.5% (46/91)] and the live birth rate [37.4% (34/91)] in group A were significantly higher than those in group B [23.0% (115/501), 29.1% (92/316), 21.8% (69/316)] ( P<0.001, P<0.001, P=0.003). Conclusion:For the aged patients, adding GH could not improve pregnancy outcomes. The application of GH in PCOS patients could increase the live birth rate. For the RIF patients, the application of GH could increase the implantation rate, the clinical pregnancy rate and the live birth rate.
