Objective:To observe the features of Henle fiber layer (HFL) in eyes with central serous chorioretinopathy (CSC) using spectral domain optical coherence tomography (SD-OCT).Methods:A cross-sectional study was conducted.Thirty-five CSC patients (35 eyes) treated in the Third People's Hospital of Qingdao from January 2017 to November 2021 were enrolled.The subjects included 23 males (23 eyes) and 12 females (12 eyes), aged 24 to 60 years old, with an average age of (41.14±8.19) years, and had a CSC duration ranged from 1 day to 6 months.SD-OCT was performed on all eyes with a line scan through the central fovea horizontally.The features of HFL over subretinal fluid (SRF) area were analyzed and summarized.The study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the Third People's Hospital of Qingdao (No.2022Y0403001).Results:In 26 eyes with regular dome-shaped neurosensory retinal detachment, HFL appeared to be delimited type 1 in 25 eyes, accounting for 96.15%, delimited type 2 in 7 eyes, accounting for 26.92%, bright in 17 eyes, accounting for 65.38% over SRF area.In 21 eyes with CSC duration≤21 days, HFL all showed delimited type 1 and some presented bright or delimited type 2 at the same time.In 5 eyes with CSC duration>21 days, HFL all showed bright and some were delimited type 1 or delimited type 2 in the meantime.In 15 eyes with symmetrical nasal and temporal retinal detachment, HFL showed symmetrical reflectivity over SRF area in horizontal OCT images in 6 eyes, and showed brighter reflectivity over nasal SRF in nasal elevated OCT images in 3 eyes and over temporal SRF in temporal elevated OCT images in 6 eyes.In 11 eyes with asymmetrical nasal and temporal retinal detachment, HFL showed brighter reflectivity over temporal SRF with larger retinal detachment range on temporal side in horizontal OCT images in 3 eyes.Of the 4 eyes with nasal elevated OCT images, the retinal detachment range was larger on temporal side and HFL showed symmetrical reflectivity over SRF area in 3 eyes, and HFL was brighter over nasal SRF area with larger retinal detachment range on nasal side in 1 eye.Of the 4 eyes with temporal elevated OCT images, the retinal detachment range was larger on nasal side and HFL showed symmetrical reflectivity over SRF area in 3 eyes, and HFL was brighter over nasal SRF area with larger retinal detachment range and higher height on nasal side in 1 eye.In 9 eyes with irregular neurosensory retinal detachment, HFL appeared to be delimited type 1 in 7 eyes, accounting for 77.78%, delimited type 2 in 5 eyes, accounting for 55.56%, bright in 6 eyes, accounting for 66.67%, dark in 4 eyes, accounting for 44.44%, and indistinct in 2 eyes, accounting for 22.22%.The detached neurosensory retina was not smooth in 7 eyes, and the phenotypes of HFL changed with the directions of detached neurosensory retina.In 2 eyes with only low neurosensory retinal detachment, HFL reflectivity on the raised side was slightly weaker than that on the lowered side.Conclusions:HFL appears to be delimited type 1 and bright mostly over SRF area in CSC in SD-OCT images.The phenotypes of HFL vary regularly with the tilt directions of OCT images, CSC duration, and the symmetry, range, height, directional characteristics of detached neurosensory retina.

Comparison study of clinical features between persistent hyperplastic primary vitreous and congenital fibrovascular pupillary membrane / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the similarities and differences of the clinical features between persistent hyperplastic primary vitreous(PHPV)and congenital fibrovascular pupillary membrane(CFPM).METHODS: Retrospectively analyze the ocular biometric parameters, clinical features and morphological changes in children with PHPV(PHPV group)and CFPM(CFPM group)who received surgery at the department of ophthalmology, Xijing Hospital from March 2006 to December 2021.RESULTS: The study included 56 cases(61 eyes)of PHPV and 24 cases(25 eyes)of CFPM. There were no differences on the gender and age of onset between PHPV and CFPM, and both of them were mainly unilaterally affected, with the ratio of 91% and 96%. Children with PHPV and cataract combined with other complications and ocular developmental abnormalities. CFPM was mainly presented different degrees of blockage and morphological abnormalities of pupillary area. In unilateral cases of PHPV and CFPM, the anterior chamber depth(ACD)of affected eyes was smaller than that of the fellow eyes, and in subgroups with age of operation ≤24mo, the axial length(AL)of affected eyes was smaller than that of the fellow eyes(P<0.05). The corneal diameter(CD)of the affected eyes in PHPV group was smaller and the intraocular pressure(IOP)was higher than those of the fellow eyes(all P<0.05); while there were no significant differences on CD and IOP between affected eyes and the fellow eyes in CFPM group(P>0.05). The ACD of affected eyes in PHPV group was significantly smaller than that of CFPM group(P<0.05). The fibrovascular membrane in PHPV group was located in the posterior part of the lens and vitreous cavity; while the fibrovascular membrane in CFPM group was located between the iris and the anterior capsule of the lens, rarely involving the lens.CONCLUSION: PHPV and CFPM had the similar clinical features, suggesting that they may belong to the different variants of persistent fetal vasculature(PFV). However, PHPV had a wider range of lesions and more complex conditions.

The role of glutamine metabolism in castration-resistant prostate cancer / 亚洲男科学杂志(英文版)

Reprogramming of metabolism is a hallmark of tumors, which has been explored for therapeutic purposes. Prostate cancer (PCa), particularly advanced and therapy-resistant PCa, displays unique metabolic properties. Targeting metabolic vulnerabilities in PCa may benefit patients who have exhausted currently available treatment options and improve clinical outcomes. Among the many nutrients, glutamine has been shown to play a central role in the metabolic reprogramming of advanced PCa. In addition to amino acid metabolism, glutamine is also widely involved in the synthesis of other macromolecules and biomasses. Targeting glutamine metabolic network by maximally inhibiting glutamine utilization in tumor cells may significantly add to treatment options for many patients. This review summarizes the metabolic landscape of PCa, with a particular focus on recent studies of how glutamine metabolism alterations affect therapeutic resistance and disease progression of PCa, and suggests novel therapeutic strategies.

Eliminat Cervical Cancer, Focusing on Primary Prevention / 肿瘤防治研究

As one of the most severe malignant tumors, cervical cancer poses a significant threat to women. In 2020, the World Health Organization (WHO) introduced the "Global Strategy to Accelerate the Elimination of Cervical Cancer" in response to well-established tertiary prevention measures. Primary prevention measures prioritize health education and the administration of prophylactic human papillomavirus (HPV) vaccines. China currently offers five HPV vaccines supported by extensive research data specific to the Chinese population. This paper discusses the application of HPV vaccines in China and related issues that need to be paid attention to.

Screening for cervical cancer and diversion of abnormal screening results / 中国医师杂志

Cervical cancer is still a serious threat to the health of women in China. The current strategy is a three-level prevention strategy, among which the diversion of screening and screening abnormalities in the secondary prevention is an important link in preventing cervical cancer. For more than 20 years, China has implemented diversified screening methods such as cytological examination, high-risk human papillomavirus (HPV) testing, and naked eye screening. With the discovery that high-risk HPV infection is closely related to the occurrence of cervical cancer, the screening method for cervical cancer has shifted from cytological examination to HPV testing as the preferred screening method. This article introduces the advantages and disadvantages of high-risk HPV testing and cytological examination as screening methods, and proposes the issues that need to be paid attention to in screening; The principle of diverting screening abnormalities was proposed, and it was proposed that in the process of diverting, individualized and refined management principles should be implemented for screening abnormality projects based on the patient′s age and fertility requirements.

Identifying the role of apolipoprotein A-I in prostate cancer / 亚洲男科学杂志(英文版)

Although localized prostate cancer (PCa) can be cured by prostatectomy and radiotherapy, the development of effective therapeutic approaches for advanced prostate cancer, including castration-resistant PCa (CRPC) and neuroendocrine PCa (NEPC), is lagging far behind. Identifying a novel prognostic and diagnostic biomarker for early diagnosis and intervention is an urgent clinical need. Here, we report that apolipoprotein A-I (ApoA-I), the major component of high-density lipoprotein (HDL), is upregulated in PCa based on both bioinformatics and experimental evidence. The fact that advanced PCa shows strong ApoA-I expression reflects its potential role in driving therapeutic resistance and disease progression by reprogramming the lipid metabolic network of tumor cells. Molecularly, ApoA-I is regulated by MYC, a frequently amplified oncogene in late-stage PCa. Altogether, our findings have revealed a novel indicator to predict prognosis and recurrence, which would benefit patients who are prone to progress to metastasis or even NEPC, which is the lethal subtype of PCa.

A novel robust nomogram based on peripheral monocyte counts for predicting lymph node metastasis of prostate cancer / 亚洲男科学杂志(英文版)

Accurate methods for identifying pelvic lymph node metastasis (LNM) of prostate cancer (PCa) prior to surgery are still lacking. We aimed to investigate the predictive value of peripheral monocyte count (PMC) for LNM of PCa in this study. Two hundred and ninety-eight patients from three centers were divided into a training set (n = 125) and a validation set (n = 173). In the training set, the independent predictors of LNM were analyzed using univariate and multivariate logistic regression analyses, and the optimal cutoff value was calculated by the receiver operating characteristic (ROC) curve. The sensitivity and specificity of the optimal cutoff were authenticated in the validation cohort. Finally, a nomogram based on the PMC was constructed for predicting LNM. Multivariate analyses of the training cohort demonstrated that clinical T stage, preoperative Gleason score, and PMC were independent risk factors for LNM. The subsequent ROC analysis showed that the optimal cutoff value of PMC for diagnosing LNM was 0.405 × 109 l

Research progress on immunomodulatory effects and mechanisms of bacterial flagellin / 中华微生物学和免疫学杂志

Flagellum is a slender and wavy protein-attached filament on the surface of certain bacterial cells. It not only plays an important role in the movement and pathogenic ability of bacteria, but also participates in a variety of host immune regulation. Flagellin is a structural protein that forms the main part of flagellar filaments and can be recognized by TLR5 and other receptors in the host cell to induce the body′s immune response. At present, flagellin is widely used in the research of new immune adjuvants due to its immune activation, and its inflammation inhibitory effect also has good prospects against immune pathological damage. In this review, we summarized and analyzed the recent progress on the basic structure and function of flagellin, the host recognition mechanism, and its role in regulating the host immune system.

Research progress on intestinal microecology regulating mechanism and biological activities of polysaccharides / 中国中药杂志

Intestinal microecology is an important defense system in the human body. The intestinal flora is the core micro-ecosystem in the human intestine. It has a symbiotic relationship with the overall functions of the body. It has strong metabolic activity to maintain the normal functioning of the body and resist the invasion of various viral antigens in the body. Playing a protective function,the imbalanced intestinal microecology can cause various diseases. Polysaccharides can be extracted from a wide range of sources and have low toxicity and side effects. They have attracted wide attention because of their anti-tumor, anti-oxidant, anti-inflammatory and other biological activities. Studies have demonstrated that polysaccharides can regulate intestinal microecological disorders. According to the studies in recent years, this review summarizes that polysaccharides mainly modulate intestinal microecological disorders through regulating the composition of intestinal flora, improving the metabolism of the flora, and repairing the intestinal tract barrier. On the basis of these mechanisms of action, this paper elaborates the anti-tumor, immunomodulatory, and anti-inflammatory activities of polysaccharides. This paper can provide reference for the future research on the intestinal microecology-regulating mechanism and biological activities of polysaccharides.

Methods:The literatures about children's balance ability, exercise and rehabilitation training were retrieved from CNKI, VIP, PubMed and Web of Science, until 2021-03-17. The authors, published time, countries, objects and their ages, study tools, interventions and the time, and outcomes were extracted. Results:A total of 2679 literatures were returned, 34 of which were enrolled, which came from 13 countries, and were almost published in journals of medicine, sports science, and rehabilitation and disabilities. The literatures were mainly published after 2010, investigate with measurements and scales. The measurements mainly included foot pressure system, force platform, Biodex balancer, etc.; and the scales mainly included Berg Balance Scale, Pediatric Balance Scale, Gross Motor Function Measure, Pediatric Evaluation of Disability Inventory, and Bruininks-Oseretsky Test of Motor Proficiency, etc. There were four typies of program: balance training, interactive computer games, virtual reality and sports events. Interventions for sick children included strength training, whole-body vibration training, Wii-Fit balance games and virtual reality treadmill training, etc. Sports for healthy children mainly included skating, Taiji Quan and gymnastics, etc. Conclusion:There are differences in the researches for children's balance ability at home and abroad. The abroad researches focus on the children with various diseases, in a larger age range, using more evaluation tools and more intervention methods. However, Chinese researches are usually for a longer intervention time, more subjects, and focusing more on healthy children. It is needed to pay more attention on children with diseases before three years old, for early diagnosis and treatment. Long-term effects should be observed other than immediateness after intervention.

Bufotenine and its derivatives: synthesis, analgesic effects identification and computational target prediction / 中国天然药物

Natural product bufotenine (5) which could be isolated from Venenum Bufonis, has been widely used as a tool in central nervous system (CNS) studies. We present here its quaternary ammonium salt (6) which was synthesized with high yields using 5-benzyloxyindole as raw materials, and we firstly discover its analgesic effects in vivo. The analgesic evaluation showed that compounds 5 and 6 had stronger effects on the behavior of formalin induced pain in mice. Moreover, the combination of compound 6 and morphine has a synergistic effect. We intended to explain the molecular mechanism of this effect. Therefore, 36 analgesic-related targets (including 15 G protein-coupled receptors, 6 enzymes, 13 ion channels, and 2 others) were systemically evaluated using reverse docking. The results indicate that bufotenine and its derivatives are closely related to acetyl cholinesterase (AChE) or α

Biomechanical characteristics of children’s different strike patterns during running / 中国组织工程研究

BACKGROUND: Foot strike patterns in adults during running have always been the focus of worldwide research, and the strike patterns of children are also something that cannot be ignored. OBJECTIVE: Using biomechanical methods to explore the differences in kinematics and kinetics of children in different strike patterns during the running process, and to provide a scientific basis for children’s correct way of running. METHODS: Seventy-four children were randomly selected from a public kindergarten in Haidian District, Beijing, and were divided into 3-year-old group, 4-year-old group and 5-year-old group. The kinematics and kinetics data of enrolled children in different strike patterns during running were acquired simultaneously using the BTS infrared motion capture system, the Kistler three-dimensional force table and the VIXTA video analysis system. The muscle strength index of the lower limbs was calculated using the Anybody 5.2 simulation modeling software. Before participation in the trial, children’s parents were fully informed of study protocol and signed the informed consent form. The trial protocol met the relevant ethical requirements of Beijing Normal University. RESULTS AND CONCLUSION: (1) In the 3-year-old group, the proportion of mid foot strike (MFS) was the highest, and the proportion of fore foot strike (FFS) was the lowest. In the 5-year-old group, the proportion of MFS was the lowest, and the proportion of FFS was the highest. The rear foot strike (RFS) extension time was longer than that of FFS (P < 0.01) and MFS (P < 0.05). (2) At the moment of landing, the flexion angle of FFS was greater than that of RFS (P < 0.01) and MFS (P < 0.05), and the flexion angle of MFS was greater than that of RFS (P < 0.05). The hip adduction-abduction angle of RFS was greater than that of FFS (P < 0.01) and MFS (P < 0.05). The maximum hip abduction angle of RFS was greater than that of FFS (P < 0.01) and MFS (P < 0.01). The amount of joint changes in the RFS hip adduction and abduction was greater than that of FFS (P < 0.01) and MFS (P < 0.05). The minimum flexion and extension of RFS was greater than that of FFS (P < 0.05). The maximal hip adduction-abduction angular velocity of RFS was greater than that of FFS (P < 0.05), and the maximal knee adduction-abduction angular velocity of RFS was greater than that of FFS (P < 0.01) and MFS (P < 0.05). (3) The muscle strength of the short bones of the tibia, the long tibia and the third metatarsal muscle of FFS and MFS was greater than that of RFS (P < 0.05). The bundle muscle strength of the medial femoral muscle, the lateral femoral muscle bundle, the lateral femoral muscle bundle, the medial femoral muscle bundle, the medial femoral muscle bundle, and the medial femoral muscle of RFS were greater than that of FFS (P < 0.01) and MFS (P < 0.05). (4) In the 3-6 years old, children often run in the heel or full-foot landing mode to meet their stability during the running process. As the age increases, the running pattern with the forefoot landing gradually appears. To keep the movement steady, RFS can trigger more hip and knee frontal motions, FFS and MFS can offer more muscle strength on the anterior and posterior sides of the calf, while RFS can offer more muscle strength on the anterior side of the thigh.

OBJECTIVE@#To observe the prevention effect of transcutaneous electrical acupoint stimulation (TEAS) for chemotherapy-related myelosuppression in non-small cell lung cancer.@*METHODS@#A total of 102 patients with non-small cell lung cancer who received initial chemotherapy were randomly divided into a conventional group, a medication group and a TEAS group, 34 cases in each one. The conventional group was treated with chemotherapy of gemcitabine combined with cisplatin and given routine care. On the basis of conventional group's treatment, the medication group was given tablets before chemotherapy, 2-3 tablets each time, 3 times a day. In the TEAS group, on the basis of conventional group's treatment, TEAS was applied at Dazhui (GV 14), Geshu (BL 17), Hegu (LI 4), Zusanli (ST 36) and Sanyinjiao (SP 6) on day 1, 2, 3, 5, 8, 14, 21 and 28 of chemotherapy. The treatment was given 30 min each time and once a day. In the three groups, the treatment for 28 days was as one course and one course of treatment was required. The changes of leukocytes, platelets, erythrocyte, hemoglobin indexes in patients of the three groups were observed one day before chemotherapy and on day 5, 8, 11, 14, 21 and 28 of chemotherapy. The comfort situation of patients was observed one day before chemotherapy and on the 5th, 11th and 21st day of chemotherapy.@*RESULTS@#Compared with before chemotherapy, the leukocyte counts of three groups were decreased at various time points after chemotherapy (<0.05). Compared with the conventional group, the leukocyte counts were higher on day 8 and 14 in the TEAS group and on day 14 in the medication group (<0.05). Compared with before chemotherapy, the platelet count decreased on the day 5, 8, 11 and 14 of chemotherapy in the conventional group (<0.05), and the platelet counts all decreased at each time point after chemotherapy in the medication group (<0.05). The platelet counts of the TEAS group on day 5, 8, 11 and 14 of chemotherapy were higher than those of the conventional group (<0.05), and the platelet counts of the TEAS group on day 5, 8, 11 and 21 of chemotherapy were higher than those of the medication group (<0.05). Compared with the conventional group, the comfort situation scores of the TEAS group were higher on the 5th and 11th days of chemotherapy (<0.05).@*CONCLUSION@#Transcutaneous electrical acupoint stimulation can prevent chemotherapy-induced myelosuppression (leukocyte, platelets) in patients with non-small cell lung cancer and improve patient comfort situation.

Evaluating the long-term prognosis of coronary artery disease patients undergoing percutaneous coronary intervention by risk stratification with ACC/AHA classification of coronary lesions / 中华心血管病杂志

Objective: To evaluate the long-term prognosis of coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI) by risk stratification with American College of Cardiology (ACC)/American Heart Association (AHA) classification of coronary lesions. Methods: Data used in this study derived from the I-LOVE-IT 2 trial. I-LOVE-IT 2 trial was a prospective, multicenter, randomized, assessor-blinded, noninferiority study. A total of 1 255 patients in I-LOVE-IT 2 trial with only one lesion and underwent biodegradable polymer drug-eluting stent implantation were included and grouped according to ACC/AHA classification of coronary lesions, namely type A/B1 lesion group (n=184), type B2 lesion group (n=457) and type C lesion group (n=614). The primary endpoint was 48-month patient-oriented composite endpoint (PoCE), a composite of all-cause mortality, all myocardial infarction, stroke, and/or any revascularization. The secondary endpoints were target lesion failure (TLF), components of PoCE, major bleeding (bleeding academic research consortium(BARC) type 3-5) and definite/probable stent thrombosis within 48 months. The incidences of endpoint events were compared in the three groups. The multivariable Cox hazard ratio model was used to analyze the independent predictors of PoCE and TLF at 48 months. Results: Incidences of PoCE at 48 months were significantly higher in patients with type C lesion compared with patients with type A/B1 (24.43%(150/614) vs. 14.13%(26/184), P<0.05) or B2 lesion (24.43%(150/614) vs. 15.97%(73/457), P<0.05). The multivariable Cox hazard ratio model showed that the type C lesion were the independent predictors of 48-month PoCE (HR=1.59, 95%CI 1.21-2.08, P<0.001) and TLF (HR=2.31, 95%CI 1.53-3.49, P<0.001). After multivariable adjustment, the HRs of PoCE for patients with type C lesion versus type A/B1 and type B2 were 1.91 (95%CI 1.25-2.92, P=0.003) and 1.64 (95%CI 1.23-2.20, P<0.001), respectively. Meanwhile, the HRs of TLF for patients with type C lesion versus type A/B1 and type B2 were 2.45 (95%CI 1.29-4.64, P=0.006) and 2.55 (95%CI 1.62-4.02, P=0.001), respectively. Conclusions: The ACC/AHA classification of coronary lesions has good discrimination with long-term outcomes for CAD patients undergoing PCI. The type C lesion is associated with a worse prognosis, enough attention should be paid in these patients during routine clinical management.

Progress in Gait Measurement and Evaluation: Application of Gait Index (review) / 中国康复理论与实践

The objective data from the three-dimensional gait analysis equipment test is complex and difficult to explain in the actual evaluation. In order to solve it, the gait index is proposed. The purpose of this review is to analyze the most commonly used gait evaluation index in clinical practice and discuss its calculation methods, advantages and limitations. The results showed that Gait Deviation Index (GDI) and Gait Profile Score (GPS) were the two most widely used indexes, but the operation of GDI was complex; the selection of parameters of Gillette Gait Index (GGI) was poor in objectivity, and the application was limited; the electromyography data is very important in the complete evaluation of gait mode, but the combination with gait indices was not close at present. The influence of gait speed has not been discussed in researches about indices except GGI.
