Objective:To analyze the incidence and clinical phenotype of the concomitant extragenital malformations in the patients with female reproductive tract anomalies.Methods:A retrospective study was conducted using clinical data of hospitalized patients diagnosed with uterine, cervical, or vaginal malformations from January 2003 to December 2022 in Peking Union Medical College Hospital. The malformations were classified according to American Society for Reproductive Medicine müllerian anomalies classification 2021, and in each type, the incidence and specific manifestations of concomitant extragnital malformations were analyzed.Results:A total of 444 patients were included. The overall incidence of concomitant extragenital malformations was 43.5% (193/444), including urinary system, skeletal system, and other system malformations. Renal malformations on the obstructed side were present in all patients with oblique vaginal septum syndrome (100.0%, 78/78). The total incidence of concomitant extragnital malformations was as high as 8/11 in uterus didelphys, 43.5% (10/23) in unicornuate uterus, 33.6% (79/235) in Mayer-Rokitansky-Küster-Hauser syndrome, 18.8% (6/32) in septate uterus and 18.5% (12/65) in cervical agenesis. Urinary system malformations (30.6%, 136/444) and skeletal system malformations (13.5%, 60/444) were the most common concomitant malformations in all types, in which, unilateral renal agenesis and scoliosis were the most common.Conclusions:Urinary and skeletal system malformations are important features of female reproductive tract anomalies. Urologic ultrasonography and spinal roentgenogram are recommended for all patients with female reproductive tract anomalies.

As one of traditional local treatments,photodynamic therapy(PDT)has mainly been used for the local eradicate and palliative treatment of malignant tumors.However,in recent years,more and more evidence has revealed a role of PDT in anti-tumor immunity,which attacked attention from researchers again.PDT can induce the immunogenic death of tumor cells as well as activation of both innate and adaptive immune systems,resulting in the enhancement of immune response against tumors.This article reviewed the advances regarding PDT and tumor immunity,aiming to systematically clarify the role of PDT in anti-tumor immunity and its potential applications in immunotherapy.

Objective:To evaluate the barrier-free level of village clinics of a city in the aging era, for references in improving the barrier-free medical environment for the elderlies.Methods:The village dectors of 156 village clinics in 12 counties of a city were selected as the objects of a questionnaire survey from Dec.2020 to Jan.2021, with 6 evaluation indexes established, each set with 1-10 points. This questionnaires was used to survey the barrier-free construction levels of village clinics. The data were statistically analyzed by rank sum ratio and quadrant graph model.Results:The barrier-free buildings of such clinics scored 32.86 points in average. Among the six indexes, the barrier-free access and doors(7.21 points) scored the highest, and the barrier-free parking space(4.71points) and toilets(3.28 points) scored the lowest. All the counties of the city fell into four categories, including 2 counties with high degree of aging-high level of accessibility, 4 counties with low degree of aging-high level of accessibility, 4 counties with low degree of aging-low level of accessibility, and 2 counties with high degree of aging-low level of accessibility, according to the quadrant graph model built based on the aging degrees and the barrier-free levels of village clinics.Conclusions:The barrier-free level of the village clinics in a city needs to be further improved, and the barrier-free transformation of parking space and toilets should also be strengthened in the future. The government should take different measures in view of conditions of each county to improve the accessibility of village clinics and facilitate the health care-seeking of elderlies.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.

Objective:To evaluate the feasibility of a new ultrasonic parameter to assess right ventricular-pulmonary artery (RV-PA) coupling in patients with acute pulmonary embolism (APE).Methods:A retrospective analysis was performed in 140 patients with APE diagnosed by computed tomography pulmonary angiography (CTPA) in the Second Affiliated Hospital of Harbin Medical University from August 2017 to June 2020. According to the tricuspid annular plane systolic excursion/pulmonary arterial systolic pressure (TAPSE/PASP) ratio cutoff value 0.40 mm/mmHg reported by the European Society of Cardiology in 2020, the patients were divided into the coupling group ( n=99) and the uncoupling group ( n=41). The conventional ultrasonic parameters of the 2 groups were measured, and then several ultrasonic parameter ratios were obtained. The new ultrasonic parameter, which can replace the TAPSE/PASP ratio, was screened out by Spearman correlation analysis, and ROC curve was plotted to calculate the diagnostic efficacy of this parameter. Results:①Compared with the coupling group, patients in the uncoupling group were older and more likely to be accompanied by dyspnea and venous thrombosis in the lower extremities (all P<0.05), but there was no significant difference in other general data(all P>0.05); ②Compared with the coupling group, tricuspid regurgitation velocity (TRV), tricuspid regurgitation pressure gradient(TRPG), PASP, right ventricle end-diastolic transverse diameter(RVTD), inferior vena cava(IVC) diameter and the ratio of early diastolic tricuspid inflow to tricuspid lateral annular velocity(E/e′), in the uncoupling group increased significantly (all P<0.05), and TAPSE, peak systolic velocity of tricuspid annulus(s′), TAPSE/PASP ratio, TAPSE/TRPG ratio, TAPSE/RVTD ratio and s′/TRPG ratio decreased significantly (all P<0.05); ③The TAPSE/TRPG ratio was highly correlated with TAPSE/PASP ratio ( rs=0.970, P<0.001); The TAPSE/TRPG ratio was still highly correlated with TAPSE/PASP ratio in the uncoupling and coupling groups ( rs=0.966, 0.922; all P<0.001). ④ROC analysis showed that the area under curve for TAPSE/TRPG in diagnosing RV-PA coupling was 0.992. At the cutoff of TAPSE/TRPG <0.625 mm/mmHg for indicating RV-PA coupling, the sensitivity and specificity were 97.6% and 92.9%, respectively. Conclusions:TAPSE/TRPG ratio can be used as a new ultrasonic parameter to reflect RV-PA coupling, which is helpful for clinical identification of APE patients with high risk and poor prognosis.

Objective:To investigate the correlation between total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C) ratio and unstable carotid plaque.Methods:From February 2021 to May 2021, adult patients with asymptomatic carotid atherosclerotic plaque admitted to the Department of Neurology, the First People's Hospital of Lianyungang were retrospectively enrolled. The demographic and related clinical data were collected. Carotid artery plaques were detected by ultrasound, and the subjects were divided into a stable plaque group and an unstable plaque group. Multivariate logistic regression analysis was used to assess the independent risk factors for unstable carotid plaques. Receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of TC/HDL-C ratio for unstable carotid plaques. Results:A total of 362 patients with asymptomatic carotid atherosclerotic plaque were enrolled, including 226 (62.43%) in the stable plaque group and 136 (37.57%) in the unstable plaque group. Multivariate logistic regression analysis showed that after adjusting for confounding factors, only TC/HDL-C ratio was the independent risk factor for unstable carotid plaque (taking the 1 st quintile array of TC/HDL-C ratio as a reference, the 4 th quintile array: odds ratio 3.13, 95% confidence interval 1.50-6.55, P=0.002; the 5 th quintile array: odds ratio 6.75, 95% confidence interval 3.21-14.22, P<0.001). ROC curve analysis showed that the area under the curve of TC/HDL-C ratio for predicting unstable carotid plaque was 0.691 (95% confidence interval 0.634-0.748; P<0.001), the optimal cut-off value was 4.38, and the sensitivity and specificity were 50.0% and 82.7%, respectively. Conclusion:TC/HDL-C ratio is an independent risk factor for unstable carotid plaques and has a certain predictive value for unstable carotid plaques.

Rhythm of blood pressure refers to the circadian variation of blood pressure, which is regulated by clock genes. However, the rhythm disorder of blood pressure increases the risk of stroke. Taking the process of blood pressure regulation as a clue and focusing on the clock gene pathway, this article explores the possible mechanism of period gene regulating renin-angiotensin-aldosterone system in rhythm of blood pressure, so as to provide reference for the in-depth study of the relevant mechanism of rhythm disorder of blood pressure and search for a new target for the primary prevention of cerebrovascular diseases.
