Objective To investigate the radiological features of intracranial white epidermoid cysts(WECs).Methods A retro-spective analysis was conducted on the CT and MRI findings of 7 patients pathologically confirmed with WECs.All patients under-went plain CT and MRI scans,and six patients underwent enhanced MRI scans.Results All cases were solitary lesions,located in the right middle cranial fossa(2 cases),suprasellar area(2 cases),left cerebellopontine angle(1 case),right cerebellar vermis(1 case),and cerebellomedullary cistern(1 case),respectively.The lesions appeared oval or irregular in shape with clear boundaries and no perile-sional edema.The CT scans predominantly showed high density in 7 cases,with calcification in 1 case.On T1WI,7 cases exhibited high signal with mixed signals in some areas;6 cases showed primarily low signal on T2WI and fluid attenuated inversion recovery(FLAIR),with 1 case predominantly showed high signal;all 7 cases demonstrated low signal on diffusion weighted imaging(DWI).The margins of 1 lesion appeared"curly",and another exhibited a"swirl"pattern.5 cases had no enhancement,while 1 case had mild marginal enhancement.Conclusion Intracranial WECs has certain imaging characteristics.When a cystic lesion shows high density on CT,predominantly high signal on T1WI,and mostly no enhancement,considering the possibility of WECs.

Objective:To analyze the factors influencing preoperative anxiety and depression in patients undergoing eye plastic surgery.Methods:A retrospective study was conducted, which included 160 patients awaiting for ocular plastic surgery at the Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January to May 2019. Among them, there were 22 males and 138 females, with an average age of (38.6±9.0) years. A one-on-one survey was conducted on enrolled patients using a paper questionnaire. The survey included general patient information, the simplified coping style questionnaire (SCSQ), the Chinese version of the Kessler 10-item questionnaire (Kessler 10), the perceived social support scale (PSSS), and the hospital anxiety and depression scale (HADS). Factors related to anxiety and depression were screened using through univariate analysis and Spearman correlation analysis, and multivariate logistic regression was used to analyze the factors influencing the anxiety and depression.Results:The detection rate for preoperative anxiety in patients undergoing eye plastic surgery was 16.3% (26/160), and that for depression was 25.0% (40/160). A total of 11.3% (18/160) of patients had both anxiety and depression. Multivariate logistic regression analysis showed that positive coping strategies ( OR=0.206, 95% CI: 0.051-0.836), depression ( OR=3.596, 95% CI: 1.068-12.107), and a high Kessler10 scale total score ( OR=1.081, 95% CI: 1.005-1.162) were related to anxiety. A monthly income of 10 000-<20 000 yuan ( OR=0.196, 95% CI: 0.044-0.875), a high total score on the Kessler10 scale ( OR=1.194, 95% CI: 1.085-1.314), and a high total PSSS score ( OR=0.913, 95% CI: 0.870-0.958) were related to depression. Conclusion:Factors affecting anxiety are positive coping strategies, depression, and a high total score on the Kessler 10 scale, while those affecting depression are a monthly income of 10 000-<20 000 yuan, a high total score on the Kessler 10 scale, and a high total score on the PSSS.

Objective:Analysis of subtype distribution characteristics of human papillomavirus (HPV) infection, pathological findings of HPV-positive patients operated colposcopy and cervical histopathological examination in Changsha from 2020 to 2022.Methods:Retrospective analysis of HPV infection status of 60 354 patients was treated in the First Affiliated Hospital of Hunan University of Chinese Medicine from Jan. 2020 to Oct. 2022. They were divided into<25 years old group (3 250 cases), 25-34 years old group (19 406 cases), 35-44 years old group (17 297 cases), 45-54 years old group (13 104 cases), 55-64 years old group (4 793 cases) and≥65 years old group (2 504 cases). Cervical exfoliated cells were collected from women and specimen of lesion site were collected from men. HPV genotyping detection used polymerase chain reaction (PCR) and flow fluorescence hybridization, which could detect 27 HPV genotypes. Analyze the distribution of HPV subtypes in patients of different age groups and different treatment departments. Analyze the relationship between the infection of HPV subtypes and the outcome of 224 patients with HPV positive who also underwent colposcopy and cervical histopathology. Pearson correlation test was used for correlation analysis, and two-tailed P<0.05 was statistically significant; Pearson chi-square test or continuous correction chi-square test was used to compare the rates between groups, and two-tailed P<0.05 was statistically significant; Chi-square split test was used to compare multiple sample rates. The standard test was corrected according to the number of groups and then compared. The difference was statistically significant when the two-tailed P value was less than the corrected standard test. Results:The overall positive rate of HPV was 16.4% (9 909/60 354). Among all HPV positive patients, affection of single type HPV accounted for 75.5% (7 479/9 909) and affection of multi-type HPV accounted for 24.5% (2 430/9 909). The top six HPV types with infection rates from high to low were: HPV52 22.8% (2 256/9 909), HPV58 11.1% (1 097/9 909), HPV53 10.5% (1 045/9 909), HPV16 9.0% (890/9 909), HPV61 7.8% (774/9 909) and HPV6 7.6% (750/9 909). The difference of overall infection rate between different age groups was statistically significant (χ 2=536.90, P<0.001). The HPV infection rate was the highest in the<25 years old group, 30.1% (978/3 250), and it is higher than the age groups of 25-34 years old, 15.6% (3 035/19 406), group of 35-44 years old, 14.2% (2 464/17 297), group of 45-54 years old, 16.1% (2 115/13 104), group of 55-64 years old, 19.1% (915/4 793) and group of≥65 years old, 16.1% (402/2 504), with statistical significance( P<0.001 respectively). The most common types of HPV infection were type 6, 16.7% (378/2 266) and type 11, 10.5% (239/2 266) in dermatology clinics. The positive rate of HPV16 accounted for 12/17 in cervical intraepithelial neoplasia (CIN) 3 and cervical cancer cases, it was significantly higher than that in the inflammatory cases, 25.0% (35/140) and CIN1 cases, 23.0% (11/48), the statistical values were χ 2=15.02, P<0.001 and χ 2=12.48, P<0.001, respectively, all of which were statistically significant. Conclusions:HPV infection rate is highest in young people under 25 years old. Low-risk HPV6 and 11 are the main types of skin and venereal diseases. Among the total cases, high-risk HPV52, 58 and 53 are the most common types of infection with women in Changsha. However, high-grade cervical intraepithelial neoplasia and cervical cancer are more closely related to HPV16 infection.

Objective:To preliminarily evaluate the efficacy and safety of stereotactic body radiotherapy (SBRT) for pulmonary oligometastatic tumors from head and neck carcinoma.Methods:Clinical data of 24 patients with pulmonary oligometastasis from head and neck carcinoma undergoing SBRT in Zhejiang Cancer Hospital from January 2014 to May 2019 were retrospectively analyzed. Survival analysis was performed by Kaplan- Meier method. Results:Among the 24 patients, 12 cases were diagnosed with nasopharyngeal origin and 12 cases of non-nasopharyngeal origin. A total of 34 pulmonary metastatic lesions were treated with SBRT. The median follow-up time was 19.5 months. Thirteen cases developed new lesions after SBRT, and 9 of them occurred within 1 year after SBRT treatment. The actual 1-year local control rate was 95%. The median progression-free survival was 15.2 months, and the 1-and 2-year progression-free survival were 59% and 46%, respectively. The 2-and 3-years overall survival rate at were 71% and 51% fter lung metastasis, respectively. Univariate analysis showed that the patients with primary lesions located in nasopharynx and disease-free interval of more than 1 year had survival advantage. No more than grade 3 radiation-induced injury was observed in the whole cohort after SBRT, and the incidence of mild radiation-induced injury was 13%.Conclusions:SBRT is safe and effective in the treatment of pulmonary oligometastatsis from head and neck carcinoma, and it may be more effective for patients with primary tumors located in nasopharynx.

Objective:To analyze the clinical value of serum 2019 novel coronavirus (2019-nCoV) immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies in the diagnosis of COVID-19.Methods:A total of 116 patients diagnosed with NCP in the First Affiliated Hospital of Hunan University of Chinese Medicine and the First Affiliated Hospital of Xiamen University were enrolled from January to February 2020 as the disease group. A total of 134 cases, including 84 non-NCP inpatients and 50 healthy individuals served as the control group. Serum samples from all subjects were collected. A fully-automated chemiluminescence immunoassay analyzer was used to detect the concentration of 2019-nCoV IgM and IgG antibodies in serum. The sensitivity and specificity of the 2019-nCoV IgM and IgG antibody single test and combined detection were compared using the χ 2 test. χ 2 test and Wilcoxon′s rank sum test were used to compare the positive rates and concentrations of IgM and IgG antibodies in NCP patients before and after their 2019-nCoV nucleic acid tests turning negative, respectively. The change trend of 2019-nCoV antibody concentration in the process of NCP patients was analyzed by Wilcoxon′s rank sum test. Results:The sensitivity of 2019-nCoV IgG (90.5%, 105/116) was higher than that of 2019-nCoV IgM (75.9%, 88/116), the difference was statistically significant (χ 2=8.91, P<0.05); The specificity of 2019-nCoV IgG (99.3%,133/134) was higher than that of 2019-nCoV IgM (94.0%, 126/134), the difference was statistically significant (χ 2=5.63, P<0.05). The sensitivity (89.7%,87/97) of 2019-nCoV IgM combined with IgG was higher than that of 2019-nCoV IgM, the difference was statistically significant (χ 2=6.89, P<0.05). The specificity (100%, 125/125) of 2019-nCoV IgM combined with IgG was higher than that of 2019-nCoV IgM, the difference was statistically significant (χ 2=7.70, P<0.05). After 2019-nCoV nucleic acid test converted to negative, the positive rate (9/17) and concentration [13.0 (4.9, 24.7) AU/ml] of serum 2019-nCoV IgM antibody were significantly lower than those when the nucleic acid test was positive, positive rate (15/17) and concentration [29.5 (14.0, 61.3) AU/ml], respectively (χ 2=5.10, Z=-3.195, both P<0.05). In the course of NCP, patients′ serum samples were collected from the first day of diagnosis to every three days, three times in total. The first 2019-nCoV IgM and IgG antibody concentrations [19.4 (12.4, 63.7) AU/ml, 105.8 (74.8, 126.1) AU/ml, respectively] were significantly higher than the second concentrations [15.8 (7.1, 40.3)AU/ml, 80.5 (66.7, 105.9) AU/ml], Z were-2.897,-3.179, both P<0.05. Conclusions:2019-nCoV IgG antibody has a good application value in the diagnosis of NCP. The concentration of 2019-nCoV IgM antibody has a certain correlation with the detection of 2019-nCoV nucleic acid. The combination of 2019-nCoV IgM and IgG antibodies with 2019-nCoV nucleic acid test may be the best laboratory index for the diagnosis of NCP at present.

Objective To investigate the effect of modified suture on the maternal skin healing, scar healing and satisfaction to cesarean section. Methods A total of 244 cases of cesarean section in our hospital from January 2015 to January 2016 were randomly collected and divided into observation group (n=143) and control group (n=101). Patients in the observation group were treated with the modified suture method, and the control group was given the conventional method to suture the skin. The VAS score, suture time and complication rate were observed in the 2 groups. Results The VAS scores were significantly lower at one week and one month after operation (1.15±0.43 and 0.07±0.01, respectively) than those of the control group (1.40±0.51 and 0.13±0.03, respectively, P<0.05). The suture time were significantly shorter in the observation group (5.12±0.95) than those of control group (7.28±0.83, P<0.05). Postoperative complication rate was significantly lower in observation group (2.80%) than that of control group (9.90%, P<0.05). The comfort level to incision and satisfaction rate to scar were significantly higher (94.41% and 95.10%, respectively) than those of control group (83.17% and 87.13%, respectively). The average thickness of scars at day 90 and day 180 after operation were significantly less in the observation group [(2.14±0.32) mm and (3.08±1.02) mm, respectively] than those of the control group [(3.10±0.48) mm and (5.22±1.10) mm, respectively, P<0.05)]. Conclusion The improved suture method after cesarean section has the advantages of shorter suture time, less poor wound healing, higher maternal satisfaction rate.
