Aquaporin 5 maintains lens transparency by regulating the lysosomal pathway using circRNA.

The lens is transparent, non-vascular, elastic and wrapped in a transparent capsule. The lens oppacity of AQP5-/- mice was increased more than that of wild-type (AQP5+/+ ) mice. In this study, we explored the potential functional role of circular RNAs (circRNAs) and transcription factor HSF4 in lens opacity in aquaporin 5 (AQP5) knockout (AQP5-/- ) mice. Autophagy was impaired in the lens tissues of AQP5-/- mice. Autophagic lysosomes in lens epithelial cells of AQP5-/- mice were increased compared with AQP5+/+ mice, based on analysis by transmission electron microscopy. The genetic information of the mice lens was obtained by high-throughput sequencing, and then the downstream genes were analysed. A circRNA-miRNA-mRNA network related to lysosomal pathway was constructed by the bioinformatics analysis of the differentially expressed circRNAs. Based on the prediction of the TargetScan website and the validation by dual luciferase reporter assay and RNA immunoprecipitation-qPCR, we found that circRNA (Chr16: 33421321-33468183+) inhibited the function of HSF4 by sponging microRNA (miR-149-5p), and it downregulated the normal expression of lysosome-related mRNAs. The accumulation of autophagic lysosome may be one of the reasons for the abnormal development of the lens in AQP5-/- mice.

Role of E2F1 and lncRNAs in the development of malignant tumors / 国际肿瘤学杂志

E2F1, a nucleoprotein gene belongs to transcription factor, is closely associated with the development of malignant tumours. Long non-coding RNAs (lncRNAs) are aberrantly expressed in a variety of tumors. In studies of molecular mechanisms associated with lncRNAs and tumours, E2F1 has been identified as a key factor that can play a critical role as an upstream regulator or downstream target of lncRNAs, and even inter-regulate to form a positive feedback loop. This paper reviews the significance of the interaction between E2F1 and lncRNA in malignant tumors in recent years, and aims to provide ideas for the study of tumor mechanisms.

DYNC2H1 gene mutation analysis and prenatal diagnosis in two pedigrees affected with short rib-polydactyly syndrome type Ⅲ / 中华围产医学杂志

Objective:To investigate the molecular genetic etiology of two fetuses with short rib-polydactyly syndrome type Ⅲ (SRPS Ⅲ).Methods:Next-generation sequencing (NGS) was used to detect 226 known genes related to inherited skeletal dysplasia in two fetuses with SRPS Ⅲ diagnosed in the First Affiliated Hospital of Zhengzhou University in August 2015 and June 2020. Suspect pathological variants were verified in the pedigree members using Sanger sequencing. The prenatal genetic diagnosis of the high-risk fetus in pedigree one was conducted to identify the confirmed pathogenic variation.Results:The homozygous mutation of DYNC2H1 gene c.5881A>G(p.Lys1961Glu) was identified in the proband in pedigree one, and the parents were the carriers. The proband in pedigree two carried compound heterozygous mutations in the DYNC2H1 gene with c.10606C>T(p.Arg3536*) inherited from the father and c.8954T>G(p.Val2985Gly) from the mother. Autosomal recessive inheritance was confirmed in both pedigrees. Mutations of c.5881A>G(p.Lys1961Glu) and c.8954T>G(p.Val2985Gly) in the DYNC2H1 gene were likely pathogenic variants and had not been reported before. The prenatal diagnosis did not identify the DYNC2H1 gene c.5881A>G(p.Lys1961Glu) mutation in the fetus (Ⅱ-7) in pedigree one, which was confirmed by the umbilical cord blood sample after birth. Conclusion:DYNC2H1 gene mutation underlies the fetal skeletal dysplasia in the two pedigrees.

Novel compound heterozygous SCN9A variations causing congenital insensitivity to pain in a patient / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis for a child featuring congenital insensitivity to pain (CIP).@*METHODS@#Targeted capture and next generation sequencing (NGS) was carried out for the proband. Suspected pathogenic variants were confirmed by Sanger sequencing of the proband and his parents.@*RESULTS@#The proband was found to harbor compound heterozygous variants of SCN9A gene, namely c.1598delA (p.N533Ifs*31) and c.295_296delCGinsAT (p.R99I), which were respectively inherited from his father and mother. Both variants were predicted to be pathogenic, and neither was reported previously.@*CONCLUSION@#The compound heterozygous variants of the SCN9A gene probably underlay the CIP in this child. Above finding has enabled genetic counseling for this family.

Clinicopathological analysis of 105 patients with fibrous dysplasia of cranio-maxillofacial region / 北京大学学报(医学版)

OBJECTIVE@#To compare the clinicopathologic features and prognosis of the different types of fibrous dysplasia (FD) of cranio-maxillofacial region, so as to provide a new reference for clinicians to treat these patients and make prognostic judgement.@*METHODS@#Clinical records, radiographic data and pathological information of 105 patients diagnosed with FD or McCune-Albright syndrome (MAS) at the Department of Oral Pathology, Peking University Hospital of Stomatology from January 2013 to December 2020 were collected. The patients were divided into 4 groups: monostotic FDs, polyostotic FDs, MAS and a specific type called craniofacial fibrous dysplasia (CFD) limited in the craniofacial region. The clinicopathological characteristics, treatment and follow-up data of each type were analyzed.@*RESULTS@#Of all the 105 patients, 46 were males and 59 were females, with a male-to-female ratio of 1 ∶1.3. The onset age ranged from 0 to 56 years and the median age was 12 years. On the basis of different involvement conditions, 4 types were divided. The most common type was monostotic FDs (43 cases, 40.95%), including maxilla (29 cases), mandibular (12 cases) and zygoma (2 cases). 32 cases (30.48%) were diagnosed with polyostotic FDs, 7 cases (6.67%) were MAS, and 23 cases (21.90%) were CFDs confirmed by computed tomography (CT) analysis. CFD was clearly distinct from other types of FD, such as the patient gender and the serum alkaline phosphatase level in peripheral blood before operative surgery. The pathologic findings of various types FD were quite similar, whilst the predominant fibrous tissue hyperplasia could be observed in polyostotic FDs and MAS types.@*CONCLUSION@#The clinicopathologic features of FD in the cranio-maxillofacial region are different from the FD lesions in other parts of the body. The clinicopathological features of CFD are significantly different from those of monostotic and polyostotic FDs in the cranio-maxillofacial region. Therefore, the clinicians should pay attention to distinguish CFD in clinic, imaging and pathology aspects, so as to further clarify its features in clinic management and prognosis.

Dilemma, causes and countermeasures of global health governance: taking COVID-19 Vaccines Global Access Facility as an example / 中华流行病学杂志

The pandemic of COVID-19 threatens the health and safety of the people all over the world. COVID-19 vaccine is the key public product to establish population immune barrier and achieve the global contain of the pandemic. The World Health Organization, the Global Alliance for Vaccines and Immunization and the Coalition for Epidemic Preparedness Innovations established COVID-19 Vaccines Global Access Facility (COVAX) in 2020, aiming to enable the fair access to COVID-19 vaccine by all countries in the world, especially the low- and middle-income countries. Although COVAX has facilitated the production and research of COVID-19 vaccine by coordinating the global supply chain, the implementation of COVAX is still facing many difficulties in financing, implementation and the awareness of public, revealing the problems of global health governance. Taking COVAX as an example, this paper analyzes the difficulties faced by global health governance and explore the underlying causes, so as to suggest feasible short and long-term paths for China's participation in global governance.

Impact of intraoperative ligation of splenic artery on prognosis of liver transplantation on patients with severe hypersplenism / 中华肝胆外科杂志

Objective:To study the impact of simultaneous ligation of splenic artery on prognosis of patients with severe hypersplenism in liver transplantation.Methods:A retrospective analysis was performed on the clinical data of 206 patients who underwent liver transplantation in the Fifth Medical Center of PLA General Hospital from December 2016 to February 2019. There were 180 males and 26 females, aged (51.0±9.0) years old. Fifty-one patients underwent splenic artery ligation during liver transplantation and they were enrolled into the observation group, and 155 patients without splenic artery ligation were enrolled into the control group. The changes in white blood cells (WBC), platelets, alanine aminotransferase, total bilirubin and serum creatinine as well as the incidence of postoperative complications were compared between the two groups.Results:The platelet count of the observation group was significantly lower than those of the control group before operation and on days 1, 3, 7, 30 and 90 after operation, (all P<0.05). The WBC counts in the observation group were significantly lower than those in the control group before operation and on days 1 and 3 after operation (all P<0.05). However, there were no significant differences in the WBC counts between the two groups on days 5, 7, 30 and 90 after operation (all P>0.05). There were also no significant differences in alanine aminotransferase and total bilirubin indexes between the two groups after surgery (all P>0.05), but the serum creatinine levels in the observation group were significantly lower than those in the control group on days 3, 5, 7 and 30 after surgery (all P<0.05). There were no significant differences in the rates of infection, severe acute rejection, biliary tract complications, arterial/portal thrombosis and mental complications between the two groups (all P>0.05). The rate of renal replacement therapy for acute kidney injury in the observation group (9.8%, 5/55) was significantly higher than that in the control group (1.3%, 2/155) ( P<0.05). Conclusion:Ligation of splenic artery during liver transplantation was safe and it had a significant advantage in the early postoperative recovery of WBC count and creatinine without increasing the incidence of complications in patients with severe hypersplenism.

Broad neutralizing nanobody against SARS-CoV-2 engineered from pre-designed synthetic library

SARS-CoV-2 infection is initiated with Spike glycoprotein binding to the receptor of human angiotensin converting enzyme 2 via its receptor binding domain. Blocking this interaction is considered as an effective approach to inhibit virus infection. Here we report the discovery of a neutralizing nanobody, VHH60, directly produced from a humanized synthetic nanobody library. VHH60 competes with human ACE2 to bind the receptor binding domain of the Spike protein with a KD of 2.56 nM, inhibits infections of both live SARS-CoV-2 and pseudotyped viruses harboring wildtype, escape mutations and prevailing variants at nanomolar level. VHH60 also suppresses SARS-CoV-2 infection and propagation 50-fold better and protects mice from death two times longer than that of control group after live virus inoculation on mice. VHH60 therefore is a powerful synthetic nanobody with a promising profile for disease control against COVID19.

Recent studies have shown that acteoside has neuroprotective activity in neurodegenerative diseases. This review examines and extrapolates from the recent literature to build support for the use of acteoside in mitigating neuropathy in neurodegenerative disease, including Parkinson ' s disease (PD) and Alzheimer' s disease (AD). We summarize the main pharmacokinetic parameters of acteoside in animals after different administration routes. Meanwhile, we point out both problems and shortcomings, and highlight its future development trend.

Genetic analysis results and ultrasonographic markers in 41 fetuses with short femurs / 中华围产医学杂志

Objective:To analyze the genetic test results and ultrasonographic markers of 41 fetuses with short femurs and their relationship.Methods:This study retrospectively analyzed 41 fetuses who were diagnosed with short femurs by ultrasound during 19-37 gestational weeks and underwent prenatal genetic examination at the First Affiliated Hospital of Zhengzhou University from January 2018 to June 2019. According to the results of genetic examination, these cases were divided into three groups after excluding three cases of variants of unknown significance: genetically normal group, chromosome variation (including chromosomal aneuploidy and pathogenic or likely pathogenic copy number variations) group, and gene mutation (including pathogenic or likely pathogenic gene mutations) group. According to the head circumference (HC), abdominal circumference (AC) and femur length (FL), Z FL, FL/HC, FL/AC, ΔZ H-F and ΔZ H+A-2F for each fetus were calculated. One-way ANOVA and LSD- t test were used for statistical analysis. Results:(1) Among the 41 fetuses with short femurs, there were 28 in the genetically normal group, five in the chromosome variation group, three with chromosome variations of unknown significance and five in the gene mutation group. (2) In the genetically normal, chromosome variation and gene mutation groups, Z FL values were -2.78±0.77, -4.36±0.69 and -4.69±0.70; FL/HC ratios were 0.178±0.011, 0.170±0.010 and 0.131±0.022; FL/AC ratios were 0.197±0.013, 0.186±0.011 and 0.151±0.017; ΔZ H-F values were 2.49±1.09, 3.53±1.28 and 8.17±1.30; ΔZ H+A-2F values were 4.44±2.00, 6.78±2.20 and 14.28±1.26, respectively. The differences in Z FL values between the genetically normal group and the chromosome variation group as well as the gene mutation group were statistically significant (both P<0.05); so were the differences in FL/HC, FL/AC and ΔZ H-F values between the gene mutation group and the genetically normal group as well as the chromosome variation group (all P<0.05) and in any pairwise comparison of ΔZ H+A-2F among the three groups (all P<0.05). Conclusions:The genetic etiology of fetal short femurs is mainly related to chromosomal variations (including chromosomal aneuploidy and pathogenic or likely pathogenic copy number variations) and gene mutation. In fetuses with chromosome variation and gene mutation, the degree of the femoral development delay relative to the development of HC and AC is worse than that in the normal genetic results group.

Characteristics on stage, scope, indication of those trials, classification and mechanism of involved products, as well as listed anticancer drugs were summarized and depicted.@*Results@#There were 474 cancer drug trials registered in China in 2019, accounting for 21.8% of the total, and 397 (83.8%) were initiated by domestic pharmaceutical enterprises. Overall, international multicenter trials accounted for 13.1%, and phase I trials accounted for 47.3%. Compared with global enterprises, the proportion of international multi-center trials initiated by domestic companies is lower (4.8% vs. 55.8%, P<0.001), and the proportion of phase I clinical trials and bioequivalence trials is higher (51.9% vs. 23.4%, 19.4% vs. 1.3%, P<0.001). An accumulative of 27 cancer types were involved for all the cancer drug trials, and lung cancer, solid tumor, and breast cancer were the most common cancer types, with 103, 95 and 49 trials, respectively. For the three cancer types unique to Chinese population, gastric, liver and esophageal cancer, the total number of initiated trials was 47. For all those trials, there were 335 cancer drug varieties, with 86.0% developed by domestic pharmaceutical enterprises, including 300 therapeutic drugs, 30 adjunctive drugs and 5 preventive drugs. In terms of mechanism, targeted drugs and immune drugs were the most popular, accounting for 74.6% and 20.3%, respectively. In addition, 17 anticancer drugs targeting on 11 cancer types were approved in China in 2019.@*Conclusions@#Clinical trials on cancer drugs in China have ushered a booming era, with large number of innovative agents represented by targeted drugs and immune drugs under clinical development or putting into clinical practice. Those local enterprises are playing more and more critical roles. Strengthening clinical research and development on Chinese unique cancer types is the key direction of future work.

Immune checkpoint inhibitors have been approved for clinical application in China. However, the increased immune-related adverse event (irAE) needs more attention. This review summarized the incidence, characteristic clinical manifestation and treatment of irAEs associated with programmed cell death protein-1(PD-1) and programmed cell death ligand-1(PD-L1) inhibitors. To have a deep insight into irAE, the potential mechanisms, the different incidences of cancer types, influencing factors and the direction of future research were also discussed here to provide guidance for clinical oncologist to identify and monitor irAE.

Genetic analysis of five pedigrees affected with multiple osteochondromas / 中华医学遗传学杂志

OBJECTIVE@#To detect variants of EXT1 and EXT2 genes among five pedigrees affected with multiple osteochondromas and provide prenatal diagnosis for the families based on the results.@*METHODS@#The EXT1 and EXT2 genes of the probands were analyzed by targeted next generation sequencing (NGS). Suspected pathological variants were validated by Sanger sequencing in the probands, their family members and 200 unrelated healthy controls. Multiple ligation-dependent probe amplification (MLPA) was used to confirm the presence of gross deletions. Prenatal diagnosis was provided for 2 couples carrying pathogenic or likely pathogenic variants.@*RESULTS@#Five variants were detected in the pedigrees, which included EXT1 exon 2-3 deletion, c.1468dupC (p.Leu490ProfsX31), c.2084delC (p.Pro695LeufsX11), and EXT2 c.187delT (p.Phe63SerfsX29) and c.1362T>G (p.Tyr454X). Among these, EXT1 exon 2-3 deletion, c.2084delC (p.Pro695LeufsX11) and EXT2 c.187delT (p.Phe63SerfsX29) were unreported previously. The three novel variants were not found among unaffected members of the pedigree and the 200 healthy controls. Upon prenatal diagnosis, the two fetuses were found to carry the same variants of the the probands.@*CONCLUSION@#Pathological variants of the EXT1 and EXT2 genes probably underlie the multiple osteochondromas among the 5 pedigrees. Prenatal diagnosis based on the results can effectively reduce the birth of further offspring affected with the disease.

Phenotypic and genetic characteristics of a child with 7p15 deletion syndrome / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis for a child with multiple malformation and growth retardation.@*METHODS@#The child was subjected to low-coverage massively parallel copy number variation sequencing (CNV-seq) based on next generation sequencing (NGS) technique.@*RESULTS@#G-banding karyotyping analysis has found no abnormality in the boy and his parents. CNV-seq analysis discovered that the child has carried a heterozygous 4.36 Mb deletion (24 020 000-28 380 000) at 7p15.3p15.1. The same deletion was not found in either parent. The deletion has encompassed 28 OMIM genes including HOXA13, CYCS, DFNA5, HOXA11 and HOXA2. Among these, HOXA13 has been associated with distal limb deformity, hypospadias and cryptorchidism. HOXA1, HOXA3 and HOXA4 are involved in the formation of cardiac primordia and primordial tube, and HOXA2 is involved in the development of auditory system. The clinical phenotype of the child was consistent with that of 7p15 deletion syndrome.@*CONCLUSION@#Haploinsufficiency of HOXA1, HOXA2, HOXA3, HOXA4 and HOXA13 genes may underlie the clinical phenotype of the child, which is comparable to 7p15 deletion syndrome.

Awareness and Influencing Factors of Clinical Trial Among Cancer Patients in China / 中国肺癌杂志

BACKGROUND@#Early investigation suggested patients' level of awareness regarding clinical trials was related with willingness to participation. This study was intended to evaluate the level of awareness of cancer patients regarding clinical trials and related influencing factors, and to compare the differences of awareness between patients who attended clinical trials before and not.@*METHODS@#From Jun, 2018 to April, 2019, standardized question-naires were gathered from cancer patients (attended clinical trials vs not attended clinical trials) in our hospital regarding basic information and 10 other questions about awareness. The level of awareness was evaluated and patients were classified into "low cognition" and "high cognition" groups. Logistic regression analysis was performed to determine whether certain characteristics would predict for awareness.@*RESULTS@#Of the 617 participants, 38.6% have attended clinical trials before. 338 (54.6%) patients had a correct overall understanding of clinical trials, while 44 (7.1%) patients still thought participants were the victim of scientific research. Except for the compensation of medical expenses (51.5% vs 48.7%) and related laws of clinical trials (52.3% vs 45.5%), other parts of understanding were elevated in patients attended clinical trials before comparing with patients who didn't, including significance (86.2% vs 77.6%), risk disclosure (91.2% vs 71.6%), confidentiality (73.2% vs 59.7%), voluntariness (95.8% vs 76.3%), withdrawal (86.6% vs 68.2%) and expenses (62.8% vs 39.2%). The proportion of participants who understand these components did not increase even in 239 patients who had attended clinical trials before. Participants who attended clinical trials before (OR=1.83, 95%CI: 1.11-3.00), unmarried/divorced (OR=5.04, 95%CI: 1.73-14.66), retired (OR=2.53, 95%CI: 1.16-5.50) had a higher level of awareness, while patients who had bad impression with doctors (OR=0.43, 95%CI: 0.26-0.72) had lower awareness.@*CONCLUSIONS@#The current level of awareness for clinical trials of cancer patients in our hospital was relatively low, even in patients who had attended clinical trials before. It's necessary to improve patients' awareness of clinical trial by promoting harmony relationship between patients and doctors, as well as by enhancing related propagation. Strengthening the adequacy and efficacy of informed consent in clinical trials also needs to be achieved in the future.

Acceptance and Related Causes of Clinical Trials among Cancer Patients in China / 中国肺癌杂志

BACKGROUND@#The clinical trials of new anti-tumor drugs are prospering in China. The acceptance of clinical trials in patients is an important factor affecting the speed and quality of clinical trials. Previous studies have investigated the acceptance of clinical trials in those cancer patients, who have never participated in a trial. This study is designed to investigate and compare the acceptance and related causes of clinical trials in cancer patients who have once participated in a clinical trial or not.@*METHODS@#From June 2018 to April 2019, a standardized questionnaire-based survey was conducted among two groups of cancer patients classified by history of clinical trial participation in Cancer hospital, Chinese Academy of Medical Science, mainly focusing on their overall acceptance of clinical trials and related considerations, including the role of attending doctors, as well as group differences between the two participants.@*RESULTS@#A total of 538 patients were enrolled with an average age of 53.5 years old, 51.1% of whom were males, and 43.3% of whom have never participated in a clinical trial. Overall, 502 patients (93.3%) were willing to or recommend their relatives or friends to participate in clinical trials, and patients with history of clinical trial participation had higher willingness (96.6% vs 90.8%, P=0.008). Patients were most likely to be motivated by expectation of optimal treatment (100.0% vs 99.3%) for both those who had once participated in a clinical trial or those not, respectively followed by financial burden reduction (56.0%) and recommendation by attending doctor (43.7%). The main reasons for unwillingness-to-participate for those who had once participated in a clinical trial were abandoning other treatment options, divided into control group or additional visits, while for those who had never participated in a clinical trial, ineffective treatment or serious adverse reactions were their main concerns. In the decision-making of clinical trial participation, 88% patients highly valued the role of recommendation by attending doctors. Among patients without trial participation history, 60.9% of those had no unwillingness-to-participate expressed that recommendation by attending doctors would change their decisions. The study also reported patients' preferences for information and access to clinical trials.@*CONCLUSIONS@#The acceptance of clinical trials in cancer patients in our hospital is generally high, especially in patients who had a history of trial participation. It's of substantial significance to give full play to the role of doctors in improving the acceptance of clinical trials of cancer patients in China.
