Objective To study the relationship between the virus content of high risk HPV and cervical intraepithelial neoplasia(CIN).Methods 450 patients with cervical intraepithelial neoplasia (CIN) were selected as the observation group ,450 healthy women at the same time were the control group ,then the positive rate and content of the control group and observation group with different high risk HPV types were detected and compared ,then the detection results of observation group with different CIN classification were compared too ,and the relationship of the detection indexes between the CIN were analyzed by the Logistic analysis .Results The HPV DNA positive rate of observation group with different high risk types were 9.11%,6.67%,6.67%,6.67%and 6.00%,respectively,and they were all higher than those of control group (χ2 =6.871,6.240,6.240,6.240,5.871,all P<0.05),and the positive rate of patients with different CIN classification had obvious differences too ,the virus content and constitution of observation group were respectively (301.35 ±32.67) Copies/mL and 11.56%,10.22%,9.56%,and they were all obviously higher than those of control group (t=6.276,χ2 =7.132,6.915,5.878,all P<0.05),and the content of patients with different classification had obvious differences ,all P<0.05,there were all significant differences ,and the item had close relationship to CIN by the Logistic analysis .Conclusion The high risk HPV virus content of patients with cervical intraepithelial neoplasia shows abnormal state ,and which have close relationship to the disease .

Objective To explore the value of serum insulin-like growth factor-1 (IGF-1) levels in diagnosis and treatment of primary hyperthyroidism. Methods 150 patients with primary hyperthyroidism (hyperthyroidism group) and 85 patients with hypothyroidism (hypothyroidism group) were selected as study subjects. During the same period, 60 healthy individuals were selected as control group. The levels of serum IGF-1, thyroid peroxidase antibody (TPOAb), thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine (T3) and total thyroxine (T4) were measured in the three groups. The serum visfatin levels in the three groups were detected using an enzyme-linked immunosorbent assay. Multifactor Logistic regression analysis was used to screen for risk factors of primary hyperthyroidism. Results The levels of IGF-1, FT3, FT4, T3 and T4 in the hyperthyroidism group were significantly higher than those in the hypothyroidism and control groups, while TSH levels were significantly lower (P < 0.05). TPOAb and visfatin levels in the hyperthyroidism group were significantly higher than those in the control group, but significantly lower than those in the hypothyroidism group (P < 0.05). The serum IGF-1 levels in patients with primary hyperthyroidism before and after 3 months of treatment were (60.11±7.23) and (30.23± 3.22) μg/L, respectively, showing a statistically significant difference (t=8.436, P < 0.001). Serum FT3, FT4, T3, T4, TPOAb, IGF-1 and visfatin levels increased and serum TSH levels decreased as risk factors for primary hyperthyroidism (P < 0.05). Conclusion The level of serum IGF-1 is closely related to thyroid function and may serve as an important reference indicator for the diagnosis and monitoring of the efficacy of primary hyperthyroidism treatment.

Objective:The expression of serum free light chain(FLC)is abnormal in various diseases,but its role in lung cancer remains unclear.This study aims to investigate the expression and diagnostic value of serum FLC in lung cancer. Methods:A total of 80 lung cancer patients treated at Xiangdong Hospital,Hunan Normal University from January to December 2021 were selected as the lung cancer group.Another 80 healthy individuals undergoing routine physical examinations during the same period were chosen as the control group.General information and serum κFLC and λFLC levels were collected for all subjects.Clinical indicators such as serum carcinoembryonic antigen(CEA),cytokeratin fragment antigen 21-1(CYFRA21-1)levels,tumor diameter,histological type,TNM stage,and lymph node metastasis status were recorded for lung cancer patients.The expression levels of serum FLC[κFLC,λFLC,and FLC(κ+λ)]were compared between the lung cancer group and the control group.Lung cancer patients were grouped based on gender,age,smoking history,tumor diameter,TNM stage,histological type,and lymph node metastasis to compare differences in serum κFLC and λFLC levels.Receiver operating characteristic(ROC)curves were used to evaluate the diagnostic value of serum FLC alone and in combination with other indicators in lung cancer. Results:The expression levels of serum FLC(κ+λ)and κFLC were significantly higher in the lung cancer group than those in the control group(both P＜0.001),while there was no significant difference in serum λFLC levels between the 2 groups(P＞0.05).There were no significant differences in serum κFLC levels among lung cancer patients with different tumor diameters,histological types,or TNM stages(all P＞0.05);however,serum κFLC levels were higher in lung cancer patients with lymph node metastasis than in those without,with statistical significance(P=0.033).There were no significant differences in serum λFLC levels based on tumor diameter or histological type(both P＞0.05),but serumλFLC levels were higher in stage Ⅲ+Ⅳ and lymph node metastatic lung cancer patients compared to stage Ⅰ+Ⅱ and non-metastatic patients,with statistical significance(P=0.033 and P=0.019,respectively).The area under the curve(AUC)for κFLC and CEA in diagnosing lung cancer showed no significant difference(P=0.333).The combination ofκFLC+CYFRA21-1 had the highest diagnostic efficacy(AUC=0.875)and sensitivity(71.3％).The AUC for the combined diagnosis of κFLC+λFLC+CEA+CYFRA21-1 was 0.915(95％CI 0.860 to 0.953,P＜0.001). Conclusion:Serum FLC is highly expressed in lung cancer and is associated with its invasion and metastasis.Serum FLC,particularly κFLC,has diagnostic value for lung cancer,and the combined detection of FLC,CEA,and CYFRA21-1 offers the best diagnostic efficacy.

As an emerging discipline that combines traditional diagnostic methods with modern scientific technology,micro syndrome differentiation has good prospects for development,but there are some controversies in the research process.Based on ancient and modern literature,this article reviewed the origin and flow of research on micro syndrome differentiation,and summarized the problems to be improved in the process of research on micro syndrome differentiation from three aspects:application of disease type,guiding ideology and micro indicators.Based on this,the article further expounded the new thinking on"near-micro"syndrome differentiation from three aspects:connotation,scope of application,and links to traditional identification and micro-identification,and pointed out that the modern medical detection basis should be incorporated into the field of TCM syndrome differentiation,and at the same time,it should be based on the overall thinking mode of TCM,which would provide a new idea for the development of modern TCM diagnosis technology.

The incidence of myopia among Chinese adolescents is progressively rising, indicating a distinct trend toward younger age onset.This paper aims to comprehensively review the impact of various visual performance on myopia and its progression, with a specific emphasis on accommodative function, convergence function, and ocular position. A meticulous exploration of accommodation function, encompassing accommodative amplitude, accommodative facility, accommodative response, positive relative accommodation, and negative relative accommodation, has been undertaken to elucidate its contributory role in myopia progression. Concurrently, an exhaustive analysis of convergence function has been conducted including esotropia and exotropia, convergence insufficiency and convergence excess, fusional function vergence, divergence insufficiency, and excess, providing a nuanced understanding of convergence's implications for myopia advancement. Furthermore, the influence of ocular position on myopia progression, along with other factors affecting perceptual ocular position and intermittent exotropia, is discussed. The primary objective of this article is to unveil the multifaceted visual performance influencing myopia and its progression, elucidating the paramount significance of accommodative function, convergence function, and ocular position in this context.
