Objective To study the clinical value of esophageal stent placement with radiation therapy for the middle-late pa-tients with esophageal cancer.Methods To perform esophageal stent placement and radiation therapy for the middle-late 35 pa-tients,and to perform radiation therapy for the middle-late 37 patients,then observe the clinical curative effects.Results The treat-ment group were significantly alleviated with dysphagia symptom after operation,which 32 cases sticked the entire radiation,ac-counting for 91.4%,no one can′t complete the treatment because of nutritional status reason.Survival time of one month after ra-diotherapy was up to 100.0%,and survival time of six months was 85.7% (30/35).But the contrast group with dysphagia symp-tom were aggravated or no relief,and needed parenteral nutrition.There were 23 cases to complete the entire radiation,accounting for 62.2%,and 5 cases happened esophageal tracheal fistula.Survival time of one month after radiotherapy was 83.8%(31/37),and survival time of six months was 62.2% (23/37).Two groups of cases in radiotherapy resistance difference was statistically signifi-cant,one month and six months of survival time were statistically significant (all P <0.05 ).Conclusion Esophageal stent place-ment with radiotherapy is more efficient than only radiation therapy to the middle-late patients with esophageal cancer.

Objective:To evaluate the feasibility of making individualized scanning and contrast injection protocol based on body mass index (BMI) and body weight during dynamic myocardial computed perfusion (CTP) imaging in order to get high-quality images while drastically reducing radiation dose.Methods:A total of 128 patients with coronary heart disease diagnosed by coronary CTA (CCTA) performed CTP from June, 2019 to March, 2020 were prospectively enrolled. Patients were divided into six groups: group 1, BMI<24 kg/m 2, ≤60 kg, 70 kV; group 2,BMI<24 kg/m 2, 61≤kg≤70, 70 kV; group 3, BMI 24-28 kg/m 2, 61≤kg≤70, 80 kV; group 4, BMI 24-28 kg/m 2, 71≤kg≤80, 80 kV; group 5, BMI 24-28 kg/m 2,>80 kg, 80 kV;group 6, BMI>28 kg/m 2,>80 kg, 100 kV. 200 mA was fixed for all patients. Contrast agent with iodine containing 370 mg/ml was used in all patients. The iodine delivery rates (IDR) for each group was 0.8, 1.0, 1.2, 1.4, 1.6, 2.0 g/s, respectively. The attenuation and noise of left ventricle (LV) and septal myocardial were measured to calculate signal to noise ratio (SNR) and contrast to noise ratio (CNR) of the images in each group. The Shapiro-Wilk test was conducted to assess the normality of quantitative data. Quantitative variables were compared using one-way ANOVA if normally distributed. Results:The LV attenuation of the six groups were (506±85), (513±77), (510±81), (456±74), (477±111), (462±43) HU, respectively. There was no significant difference among them ( F=2.249, P=0.054). SNR values of LV were 23±8, 20±5, 21±5, 19±4, 19±7, 19±4, and CNR values were 19±7, 17±4, 17±4, 16±4, 15±6, 15±4, respectively. There were no significant differences among them ( F=1.674, 1.736, all P>0.05). Under a single CTP scan, the radiation dose of 70, 80 and 100 kV groups were 1.6, 2.3 and 4.3 mSv, respectively. The does of the 70 kV group and 80 kV group were significantly lower than that of the 100 kV group, and the dose of the 70 kV group was also significantly lower than that of the 80 kV group (all P<0.001). Conclusions:The application of individualized scanning and contrast agent injection protocol based on IDR is feasible in myocardial CTP with successful image quality, and the radiation dose decreases significantly.

Objective:Currently,traditional cervical cancer screening methods,such as high-risk human papillomavirus testing and liquid based cytology(LBC),still possess limitations.This study aims to identify new diagnostic biomarkers to achieve the goal of"precision screening"via exploring the clinical value of DNA methylation[ΔCtP:paired box gene 1(PAX1)and ΔCtJ:junctional adhesion molecule 3(JAM3)]detection in cervical exfoliated cells for the diagnosis of high-grade cervical lesions. Methods:A total of 136 patients who underwent gynecological examinations in the vaginal room of the Department of Gynecology at the Third Xiangya Hospital of Central South University from June 2021 to June 2022 were retrospectively studied.Among them,122 patients had non-high-grade cervical lesions,and 14 patients had high-grade cervical lesions.The variables included general information(age,body mass index,and menopause status),LBC,high-risk human papillomavirus,cervical tissue pathology,vaginal examination results,and the ΔCt values of JAM3 and PAX1 gene methylation.Logistic regression analysis was used to identify the factors affecting the diagnosis of high-grade cervical lesions,followed by correlation analysis and construction of a conditional inference tree model. Results:Logistic regression analysis showed that the methylation ΔCt values of PAX1 and JAM3 genes and LBC detection results were statistically significant between the high-grade cervical lesions group and the non-high-grade cervical lesions group(all P<0.05).Correlation analysis revealed a negative correlation between cervical pathological changes and ΔCtP(r=-0.36,P<0.001),ΔCtJ(r=-0.448,P<0.001),LBC(r=-0.305,P<0.001),or bacterial diversity(r=-0.183,P=0.037).The conditional inference tree showed that when ΔCtJ>10.13,all of patients had non-high-grade cervical lesions,while ΔCtP>6.22,the number of non-high-grade lesions accounted for 97.5%(117/120),and high-grade lesions accounted for only 2.5%(3/120).When ΔCtJ>8.61 and LBC were atypical squamous cell of undetermined significance or negative for intraepithelial lesions or malignancy(NILM),105(99.1%)patients were non-high-grade cervical lesions,only 1(0.9%)patient was high-grade lesion.When the results of LBC were high-grade lesions,only 9 patients'histopathological examination was the high-grade lesions and 3 non-high-grade lesions.When LBC indicated low-grade lesions,atypical squamous cell of undetermined significance,no intraepithelial lesions,and ΔCtP>6.22,117(97.5%)of patients'histopathological examination was the non-high-grade lesions. Conclusion:The JAM3/PAX1 gene methylation test can be used independently for the stratified diagnosis of high-grade/non-high-grade cervical lesions in women with high-risk human papillomavirus infection,independent of the cytological results of cervical excision.The JAM3/PAX1 gene methylation test can also be used in combination with LBC to make up for the shortcomings of low sensitivity of LBC.In addition,the application of methylation kit in large-scale cervical cancer screening in the future will be good to the detection of more patients with high-grade cervical lesions,and achieve early screening and early treatment for cervical lesions/cancer.

Objective:Uterine adhesion is mainly caused by endometrial injury,leading to poor postoperative pregnancy outcome.Therefore,preoperative evaluation on uterine cavity,especially endometrial condition,is very necessary.This study aims to explore the correlation between preoperative three-dimensional transvaginal ultrasound(3D-TVS)imaging characteristics and postoperative pregnancy outcomes after hysteroscopic adhesiolysis(HA). Methods:A total of 401 patients,who underwent HA surgery from February 22,2018 to October 31,2018 at the Third Xiangya Hospital of Central South University or Changsha Jiangwan Hospital,were enrolled,and we collected data regarding the preoperative 3D-TVS imaging characteristics and followed up their postoperative pregnancy outcomes.Correlation analysis and univariate and multivariate logistic regression analysis were performed between imaging features and pregnancy outcomes(live and non-live birth outcomes)in patients with intrauterine adhesion. Results:The results of correlation analysis showed that endometrial thickness,endometrial echo,visible tubal openings,endometrial blood flow,intercornual distance,and endometrial peristalsis were correlated with the live birth rate(all P<0.05).Logistic regression analysis revealed that in the HA patients with the live birth,the endometrial thickness was thicker(P<0.001),endometrial echo was more homogeneous(P<0.001),the number of tubal openings was more(P<0.001),the intercornual distance was wider(P<0.05),the endometrial blood flow,and irregular cases of endometrial peristaltic waves were more and cases of deficiency were fewer(both P<0.01)than those in the non-live birth group. Conclusion:Preoperative 3D-TVS imaging performance is closely related to pregnancy outcomes of HA patients,and preoperative 3D-TVS can be used to predict pregnancy outcomes after HA.

Objective:To investigate the role of concurrent chemoradiotherapy in the treatment of limited-stage small cell lung cancer (LS-SCLC) and the impact of the number of chemotherapy cycle during radiotherapy (RT) on clinical prognosis.Methods:Patients with LS-SCLC treated with definitive radiotherapy from May, 2008 to September, 2016 were included in the study. The primary endpoint was overall survival (OS), which was calculated from the start of treatment to the date of death or last follow-up. The effect of the number of concurrent chemotherapy cycle and other clinical factors on clinical efficacy was analyzed. Survival analysis was performed with Kaplan- Meier method, and multivariate analysis was performed with Cox regression model. Results:Three hundred and seventeen patients were eligible for the analysis. Among them, 129 patients received sequential chemoradiotherapy and 188 patients received concurrent chemoradiotherapy. Among patients receiving concurrent chemoradiotherapy, 86 patients received 1 cycle of concurrent chemotherapy and 102 cases of 2 cycles of concurrent chemotherapy. The median follow-up time was 22.47 months. Multivariate survival analysis showed that only clinical stage, timing of RT administration and prophylactic cranial irradiation (PCI) were the independent prognostic factor for OS. The median OS in patients who received 1 cycle and 2 cycles of concurrent chemotherapy during RT were 33.8 months and 30.4 months ( P=0.400). No matter in elder patients or in younger patients, in early RT group or in late RT group and application of PCI or not, the number of concurrent chemotherapy cycle exerted no significant impact on OS. The incidence of grade 3 or above adverse events was 20% in the 1-cycle concurrent chemotherapy group, and 13.7% in the 2-cycle concurrent chemotherapy group. Conclusions:Concurrent chemoradiotherapy is the standard treatment of LS-SCLC. Two cycles of concurrent chemotherapy during RT is not necessarily superior to 1 cycle of concurrent chemotherapy. The optimal number of concurrent chemotherapy cycle during RT need to be studied in a large prospective randomized clinical trial.

Objective:To analyze clinical characteristics of neurosyphilis patients with abnormal mental behaviors as the initial symptom, and to provide a reference for clinical classification of, as well as outcome prediction and efficacy monitoring in neurosyphilis.Methods:Clinical data were collected from 67 HIV-negative neurosyphilis patients with abnormal mental behaviors as the initial symptom in the Second Affiliated Hospital of Soochow University from November 2012 to November 2019, and retrospectively analyzed. Statistical analysis was carried out by using t test. Results:Among the 67 patients, 52 (77.6%) were males, and 15 (22.4%) were females; there were 63 (94.0%) middle-aged and elderly patients and 4 (6.0%) adolescent patients; 38 (56.7%) patients were diagnosed with progressive general paresis, 21 (31.3%) with meningovascular neurosyphilis, 1 (1.5%) with meningeal neurosyphilis, 3 (4.5%) with tabes dorsalis, and 4 (6.0%) with mixed-type neurosyphilis. As laboratory examination showed, 67 patients all presented with positive serum rapid plasma reagin (RPR) test, serum Treponema pallidum particle agglutination (TPPA) test, and cerebrospinal fluid TPPA test, 55 (82.1%) had positive cerebrospinal fluid RPR test, 47 (70.1%) had elevated cerebrospinal fluid protein levels of > 0.45 g/L, 50 (74.6%) had increased white blood cell counts of > 8 ×10 6/L in cerebrospinal fluids, and 28 (41.8%) had elevated IgG levels in cerebrospinal fluids. Magnetic resonance imaging of the brain revealed multiple ischemic foci in 21 (31.3%) cases, multiple leukodystrophy in 17 (25.4%) , cerebral atrophy in 15 (22.4%) , infarction in 8 (11.9%) , and encephalitis-like changes in 2 (3.0%) . Of the 67 patients, 48 were treated with penicillin in aqueous solutions, 15 with ceftriaxone, and 4 with doxycycline. Six months later, the follow-up showed that 46 (68.7%) patients responded to the treatment, and the early course of disease was significantly shorter in the highly responsive group than in the poorly responsive group ( P < 0.05) . Conclusion:The middle-aged and elderly males were predominant in the neurosyphilis patients with abnormal mental behaviors as the initial symptom, magnetic resonance imaging is helpful for clinical classification and prognosis prediction of neurosyphilis, and early and standardized antisyphilitic treatment can markedly improve the prognosis of patients.

Objective:This work aims to explore the application value of cervical exfoliated cell DNA (Cysteine dioxygenase type 1, CDO1 and CUGBP Elav-like family member 4, CELF4) methylation in the detection of endometrial cancer in women of childbearing age. Methods:From November 2021 to October 2022, a prospective study was conducted on a total number of 517 reproductive-age women with abnormal uterine bleeding who had surgical indications for hysteroscopy at the Xiangya Third Hospital of Central South University. The cervical exfoliated cells were collected for cytology, HPV (human papillomavirus) and gene methylation detection before operation. Clinical information of patients, level of tumor-related biomarkers, and endometrial thickness of transvaginal ultrasound (TVS) were also collected. Single factor regression method was used to analyze the high-risk factors of endometrial cancer. Receiver operating characteristic curve analysis was used to obtain the area under the curve(AUC), focusing on the screening efficacy of gene methylation test for endometrial cancer in women of childbearing age.Results:The age, body mass index (BMI)≥25 kg/m 2, endometrial thickness≥11 mm, CDO1 m ΔCt≤8.4, CELF4 m ΔCt≤8.8, and double gene methylation were associated with endometrial cancer in women of childbearing age, 1.16(1.08-1.25), 4.33(1.89-10.31), 9.49(3.88-26.69), 69.62(25.70-224.36), 23.64(9.66-63.99), 87.39(24.83-555.05), all P<0.05. The AUC was 0.90 (95% CI 0.83-0.97) of CDO1 m/ CELF4 m in diagnosing endometrial carcinoma was higher than others factors, with sensitivity and specificity of 91.7% (95% CI 80.6%-100%) and 88.8% (95% CI 86.0%-91.6%). TVS combined with DNA methylation detection further improved the sensitivity to 95.8% (95% CI 87.8%-100%), but could not improve the specificity 68.0% (95% CI 63.8%-72.1%). Conclusions:For women of childbearing age with abnormal uterine bleeding or abnormal vaginal discharge, the accuracy of cervical cytology DNA methyl detection of endometrial cancer is better than other non-invasive clinical programs. DNA methylation combined with TVS can improve the sensitivity of detection.

This study was aimed to analyze the application of non-pharmacotherapy in treating cervical radiculopathy (CR) in real-world,and to provide clinical reference for CR non-pharmacotherapy.The clinical real-world data of CR was extracted by using information sharing system of traditional Chinese medicine (TCM) and clinical research.Six hundred and twenty-eight inpatients and outpatients with CR were enrolled from December 2012 to July 2014 in the information system database of Wangjing Hospital.Basic characteristics of the non-pharmacotherapy groups were analyzed by statistical description method.The node degree and mutual information value were recorded for non-pharmacotherapy application of all patients by using liquorice software.Complex network diagrams were generated.The results showed that 47％ of CR patients received non-pharmacotherapy (294/628),including 67 males and 227 females.The average age of patients was 49 years old,and the prevalence of the disease was the highest from 45 to 65 years old.In all patients,the usage of manipulation and cervical traction was higher,and the combination of manipulation and acupuncture was the most.Within outpatients,the proportion of cervical traction was higher,and the combination of manipulation and acupuncture was the most frequently.Within inpatients,the proportion of manipulation and cervical traction was higher,and the combination of comprehensive physical therapy and exercise therapy was the most frequently.It was concluded that non-pharmacotherapy has been commonly used in clinical treatment of CR.Cervical traction and manipulation was the widest applications.The combination treatment was in wide application.Future studies should increase the sample size of CR patients from different regions,and enhance gradually the level of evidence of clinical research for non-pharmacotherapy treating CR.

The septate uterus is the most common structural uterine anomalies and it is associated with the poor reproductive outcome. It is believed to be the result of the failure in resorption of the tissue connecting the 2 paramesonephric ducts prior to the 20th embryonic week. The true prevalence of uterine septum is difficult to ascertain, as many uterine septal defects are asymptomatic. The septate uterus is usually diagnosed during an infertility evaluation and affects reproductive health by impairing fertility and increasing adverse pregnancy outcomes. The variations in uterine and cervical/vaginal anomalies collectively referred to as Müllerian anomalies. No consistent gold standard for the diagnosis of Müllerian anomalies exists. The preferred diagnostic method for Müllerian anomalies is two-dimensional ultrasound, other methods such as three-dimensional ultrasound, magnetic resonance imaging, hysterosalpingo contrast sonography, hysterosalpingography, hysteroscopy, and laparoscopy are also used to improve accuracy.

Although there is insufficient evidence supporting the link between septate uterus and infertility, there are many studies demonstrated the effect of spetal incision on pregnancy in women diagnosed with septate uterus associated with infertility. Hysteroscopic metroplasty can significantly improve the reproductive performance of those with septate uterus. Some Müllerian malformations can be healed by surgery. The accurate diagnosis and appropriate therapeutic approch are fundamental for successful treatment. Any attempt at surgical correction of uterine abnormalities must be aimed at preserving or improving reproductive function. Among congenital uterine anomalies, septate uterus is the most amenable to simple hysteroscopic treatment. The resection of the septum is performed as standard treatment worldwide.
