Abstract
Objective: To clarify the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant on the performance of existing molecular diagnostic assays, and investigate the detection ability of clinical laboratories across China. Methods: The first nationwide external quality assessment (EQA) for molecular detection of Delta variant was carried out based on the non-infectious phage virus-like particles samples, which were prepared by genetic engineering methods and distributed to 8 488 laboratories nationwide. The EQA panel was composed of three Delta variant samples (7.5×102, 1.5×103 and 6.0×103 copies/ml), one non-variant weak positive sample and one negative sample. The percentage of agreement (PA) of Delta variant samples with different concentration, the PA of Delta variant and non-variant samples with 7.5×102 copies/ml, the PA of assays used by more than 100 laboratories for Delta variant samples with different concentration and the PA of Delta variant and non-variant samples with 7.5×102 copies/ml were calculated and analyzed. Results: The data from 8 127 laboratories were available for evaluation. The testing capability of 98.77% (8 027/8 127) of the participating laboratories was found to be competent in reporting correct results for all samples. The overall percentage of agreement (OPA), negative percentage of agreement (NPA) and positive percentage of agreement (PPA) of the samples were 99.64% (40 490/40 635), 99.73% (8 105/8 127), 99.62% (32 385/32 508), respectively. With the decrease of the concentration of the samples, the PPA of Delta variant samples decreased. The PPAs were 99.41% and 99.51% for Delta variant and non-variant samples with 7.5×102 copies/ml, respectively, with no statistical difference (P=0.392). The OPA, NPA and PPA of the assays used by more than 100 laboratories were all greater than 98%, and no statistical difference of the PPAs was identified between Delta variant and non-variant samples with 7.5×102 copies/ml (P>0.05). Conclusions: Delta variant fails to impair the performance of current molecular diagnostic assays in China. The clinical laboratories have the same detection capabilities for Delta variant and non-variant samples. However, in certain laboratories, further improvement is required to ensure the accurate detection of weak positive samples.

Abstract
The 17α-hydroxylase/17, 20-lyase deficiency (17-OHD) is a rare disease. The clinical characteristics and gene mutation of 2 late-diagnosed 17-OHD patients with testicular tumor admitted to our hospital from March 2018 to February 2019 were analyzed retrospectively. The two 17-OHD patients were female (46, XY). Laparoscopic abdominal exploration found undeveloped testicles in grey-yellow or grey-red in the groin and iliac fossa. The testicles were removed and showed malignancy in pathology study. Sequencing of the CYP17A1 gene identified c.1247G>A/c.1427T>C and c.985_987delTACinsAA/c.1306G>A complex heterozygous mutations. Taking together, the possibility of 17-OHD should be considered in patients with hypertension, hypokalemia, adrenal adenomatoid hyperplasia together with 46, XY gonadal dysplasia, so as to make early diagnosis and treatment, and avoid dysplastic testicular turning to malignancy.

Abstract
Objective: To investigate the distribution of noise exposure between non-steady state noise and steady-state noise for metal processing workers, which will provide scientific basis for the prevention and treatment of noise hazards in metal processing industry. Methods: The cross-section method was used to investigate the noise exposure of 737 workers from three metal processing industries in Zhejiang Province from October to December 2017. The general demographic information and occupational history were collected by questionnaire. The noise was recorded by individual noise meters, and the noise exposure intensity (equivalent continuous A-weighted noise exposure level normalized to an 8 h-working-day, L(Aeq, 8 h)) and kurtosis were calculated. Results: Workers exposed to noise in the metal processing industry were mainly 18-40 years old (527 workers, 71.51%) , men (570 workers, 77.34%) , and junior high school education background (416 workers, 56.45%) . There were 572 workers (77.61%) with noise exposure intensity (L(Aeq, 8 h)) greater than 85 dB (A) , 558 workers (75.71%) exposed to non-steady state noise (kurtosis ≥4) , and 634 workers (86.02%) with exposure duration less than 8 years. Among the 30 work types investigated, the work types with noise intensity reaching 100% were the stamping, welding and others from a children's car manufacturing factory in Ningbo, operating, chamfering, tapping, and thread rolling from an automobile parts manufacturing factory in Ningbo; The work types with a rate of 100% exposed to non-steady state noise were the grinding from a children's car manufacturing factory in Ningbo, assembling, assembly operating and others from an automobile brake manufacturing factory in Wenzhou, and polishing from an automobile parts manufacturing factory in Ningbo. Conclusion: Metal processing workers have a high rate of over-standard exposed to high noise intensity and a high proportion exposed to non-steady state noise. It is necessary to take sound insulation and noise reduction engineering control, and strengthen personal protection and occupational health management measures to prevent and control the noise hazards.

Abstract
Objective: To investigate the impact of perioperative anesthesia management with enhanced recovery after surgery (ERAS) strategy on postoperative recovery in patients undergoing laparoscopic surgery for gynecologic malignancy. Methods: Ninety patients undergoing laparoscopic surgery for gynecologic malignancies from April 2018 to April 2019,aged 18-65 years,with American Society of Anesthesiologists (ASA) physical status Ⅰ or Ⅱ, were recruited and randomly divided into two groups (n=45) using a random number table:ERAS group (group E) and control group (group C). Patients in group E received general anesthesia combined with transverses abdominis plane block and a series of interventions to optimize anesthetic and perioperative management, while patients in group C were treated with routine anesthesia management. Quality of Recovery-40 questionnaire (QoR-40) was administered to assess the early postoperative quality of recovery on 1 day before surgery, and at 24 and 48h after surgery. C-reactive protein (CRP) before and after the operation were evaluated. The incidence of nausea, vomiting and shivering, the time of first exhaust, ambulation, resumption of normal diet, postoperative hospital stay and complications were recorded. Results: The scores of QoR-40 [M(Q1, Q3)] in Group E were 175(171, 179) and 185(183, 189) at 24 h and 48 h after operation, which were higher than those in group C [162(160, 167) and 180(179, 183)] (both P<0.01). The levels of CRP in both group E and group C increased at 24 h and 72 h after operation. Moreover, the extent of increasing level of CRP in group C was much higher than that in group E [(39.8±18.0) mg/L vs (13.4±6.3) mg/L, (16.6±8.6) mg/L vs (6.7±2.5) mg/L] at 24 h and 48 h after operation (both P<0.01). Compared with group C, the numerical rating scale (NRS) for nausea decreased significantly in group E [0(0, 2) vs 3 (0, 5), P<0.01]. Meanwhile, the incidence of vomiting and shivering in group E was lower than that in group C [8.9% (4/45) vs 26.7% (12/45); 11.1% (5/45) vs 31.1% (14/45); both P<0.05]. The time of first exhaust, ambulation and resumption of normal diet in group E was (14±6) h, 6(6, 13) h and 1(1, 2) d, respectively, which was markedly shorter than that in group C [(25±10) h, 21(19, 27) h and 3(2, 3) d] (all P<0.01). Overall, the postoperative length of hospital stay reduced significantly for patients who followed the ERAS protocol [7(5, 11) d vs 10(7, 14) d, P<0.01]. The incidence of postoperative complications was 17.8% (8/45) and 37.8% (17/45) in group E and group C, respectively, with a significant difference (P<0.05). Conclusion: Implementation of ERAS anesthesia management in gynecologic oncology patients undergoing minimally invasive surgery alleviates perioperative discomfort, decreases surgical stress response, and improves the early postoperative quality of recovery.

Abstract
Objective: To explore the progress of small shadow and the change of lung function in pneumoconiosis with positive autoantibody, so as to provide basis for clinical treatment of pneumoconiosis. Methods: A total of 756 patients were admitted to the pneumoconiosis department of the Guangzhou Occupational Disease Prevention Hospital from January 1, 2013 to June 1, 2019. The patients with combined infection were excluded. According to whether the autoantibody was positive, they were divided into positive group and negative group, 25 cases in each group. Follow-up observation of X-ray chest radiographs, chest CT, forced expiratory volume in one second (FEV(1)) and forced expired flow at 50% of FVC (MEF(50)) of pneumoconiosis patients for 5 years, to analyze the influence of positive autoantibody on the morphology of X-ray chest film, the pneumoconiosis promotion in 5 years and lung function. Results: There were 22 males and 3 females in the autoantibody positive group, aged 53.14±10.51 years. In the autoantibody negative group, there were 23 males and 2 females, aged 53.88±8.10 years. During the 5-year observation period, there was no significant difference of small shadow shape, pneumoconiosis stage, and the pneumoconiosis promotion in 5 years between the autoantibody positive group and the autoantibody negative group (P>0.05). However, the increment of small shadow area in the autoantibody positive group was higher than that in the autoantibody negative group (P<0.05). FEV(1) and MEF(50) of the autoantibody positive group were significantly lower than those of the autoantibody negative group in the fourth and third years, respectively (P<0.05). Positive autoantibody was negatively correlated with FEV(1) and MEF(50) (P<0.05). Conclusion: The positive autoantibody can't promote the progress of X-ray, but show more small shadows on chest CT; the positive autoantibody may aggravate the decline of lung function.

Abstract
The mangrove Kandelia obovata (Rhizophoraceae) is an important coastal shelterbelt and landscape tree distributed in tropical and subtropical areas across East Asia and Southeast Asia. Herein, a chromosome-level reference genome of K. obovata based on PacBio, Illumina, and Hi-C data is reported. The high-quality assembled genome size is 177.99 Mb, with a contig N50 value of 5.74 Mb. A large number of contracted gene families and a small number of expanded gene families, as well as a small number of repeated sequences, may account for the small K. obovata genome. We found that K. obovata experienced two whole-genome polyploidization events: one whole-genome duplication shared with other Rhizophoreae and one shared with most eudicots (γ event). We confidently annotated 19,138 protein-coding genes in K. obovata and identified the MADS-box gene class and the RPW8 gene class, which might be related to flowering and resistance to powdery mildew in K. obovata and Rhizophora apiculata, respectively. The reference K. obovata genome described here will be very useful for further molecular elucidation of various traits, the breeding of this coastal shelterbelt species, and evolutionary studies with related taxa.

Abstract
Theories beyond the standard model often predict the existence of an additional neutral boson, the Z^{'}. Using data collected by the Belle II experiment during 2018 at the SuperKEKB collider, we perform the first searches for the invisible decay of a Z^{'} in the process e^{+}e^{-}→μ^{+}μ^{-}Z^{'} and of a lepton-flavor-violating Z^{'} in e^{+}e^{-}→e^{±}μ^{∓}Z^{'}. We do not find any excess of events and set 90% credibility level upper limits on the cross sections of these processes. We translate the former, in the framework of an L_{μ}-L_{τ} theory, into upper limits on the Z^{'} coupling constant at the level of 5×10^{-2}-1 for M_{Z^{'}}≤6 GeV/c^{2}.

Abstract
Retrospective analysis of 18 cases of occupational acute 1, 2-dichloroethane (1, 2-DCE) poisoning. The results showed that all patients have the main manifestations such as dizziness, headache, unresponsiveness and other symptoms of nervous system damage; Brain CT showed varying degrees of diffuse white matter lesions. Brain MRI showed extensive involvement of white matter in both cerebral hemispheres. Affected white matter area presented low intensity on T1WI, hyperintensity on T2WI and T2-Flair; Lumbar puncture examination of cerebrospinal fluid (CSF) pressure (262.5±48.39) mm H(2)O; After treatment, the required time for CSF pressure to restore was (161.56±75.27) days (50-280) days. Summary, Occupational acute 1, 2-DCE poisoning caused by toxic encephalopathy can be manifested as persistent abnormalities in CSF pressure, and the CSF pressure drops slowly during treatment; Early head CT and lumbar puncture examination will be helpful for early detection of intracranial pressure in toxic encephalopathy caused by acute 1, 2-DCE poisoning. Dynamic monitoring of CSF provides guidance for acute 1, 2-DCE poisoning with a long time of treatment and various types of dehydrating agents.

Abstract
Objective: To observe changes in foveal avascular zone(FAZ) and capillary plexus in idiopathic macular epiretinal membrane (IMEM) in optical coherence tomography angiography (OCTA) and analyze their correlation with the visual acuity. Methods: Cross-sectional study. 42 patients (15 Males and 27 females, age 64.8) from the Eye Hospital of Wenzhou Medical University were included with 51 eyes diagnosed as IMEM (IMEM group), and 23 normal eyes (9 Males and 14 females, control group). All patients received the examination of fissure lamp combined with fundus pre-set lens, best corrected visual acuity (BCVA), OCT angiography (OCTA) and fundus photo. OCTA was performed on 3 mm× 3 mm sections centred on the fovea. The software automatically measured the superficial capillary plexus (SCP) and deep capillary plexus (DCP) vessel density(VD) and retinal thickness(RT) and FAZ area. The IMEM eyes were compared with the normal eyes and correlation between the parameters of OCTA and BCVA was analyzed in IMEM. Independent-sample t test and MannWhitney test were used for comparison between groups, and Spearman test was used for correlation analysis. Results: LogMAR BCVA in the IMEM group was 0.40(0.15, 0.70), in the control group was 0.10(0.05, 0.22). FAZ area of IMEM group was (0.09±0.05) mm(2), while that of control group was (0.34±0.13)mm(2).Compared with the control group, in IMEM group, the BCVA was worse (Z=-4.443, P<0.001), FAZ area was smaller (t=-9.198, P<0.001), RT was increased (P<0.001), The foveal DCP and SCP vessel density was increased (t=4.280, 9.079, P<0.01), The parafoveal DCP vessel density was decreased (P<0.05), The parafoveal SCP vessel density was decreased in superior, inferior and nasal side (t=-2.759, Z=-3.998, Z=-2.108; P<0.05). The BCVA was negatively correlated with FAZ area (r=-0.337, P=0.017), positively correlated with center macular thickness (r=0.324, P=0.020). The BCVA was no correlated with foveal VD and parafoveal DCP vessel density (P>0.05), but correlated with SCP vessel density(P<0.05). Conclusions: In the IMEM eyes the BCVA was worse, FAZ area was smaller, foveal vessel density was increased and the parafoveal vessel density was decreased compared with the normal eyes. The smaller the FAZ area, the smaller foveal SCP vessel density, the poorer BCVA. There was no correlation between BCVA and DCP vessel density. Changes in VD in IMEM eyes may lead to changes in vision. (Chin J Ophthalmol, 2019, 55:757-762).

Abstract
Pollinators foraging for food resources can be waylaid by mass-flowering plants located in their foraging pathway in landscapes. The waylaying effect of pollinators is often studied at a single spatial scale; to date, little is known about the best spatial extent at which waylaying effect of pollinators can be measured. In this study, we selected a landscape with mass-flowering tufted vetches to determine the spatial scale of waylaying effect of honey bees as well as the consequence of waylaying effect on vetch pollination service. The spatial scale of waylaying effect was determined by the strongest association between honey bee density and distance, selected from a gradient of nested circular buffers centering on apiaries in three different locations. Linear models were used to predict the influence of flower visitor densities on pollination service. For our landscape, honey bee densities were best associated with distances at spatial scales of 500 m, 1150 m, and 1400 m respectively for the three locations of apiaries. Honey bee was the only pollinator whose density displayed a positive relationship with pollination service. At the scales of effect, honey bee density and pollination service declined along the distance. Our findings suggest that the waylaying effect of pollinators needs to be examined at a specific spatial scale and farmers who use honey bees to pollinate their mass-flowering crops need to consider the spatial scale of waylaying effect of pollinators in order to maximize pollination service within agricultural ecosystems.

Abstract
Objective: To analyze 8 cases of paraquat lung transplantation in the world, and to explore the timing of lung transplantation and the factors affecting prognosis. Methods: An analysis of the clinical data of a paraquat poisoning lung transplant patient completed by The 12th People's Hospital of Guangzhou Medical University and The First People's Hospital affiliated to Guangzhou Medical University in August 2017 and literature review. Results: A 26 years old female patient was admitted to the hospital ingested 20% paraquat solution 20ml. On the 58th day of poisoning, she underwent double lung transplantation under general anesthesia. The operation was successful. Excised lungs show extensive lung fibrosis in both lungs, which was consistent with paraquat poisoning. Used tacrolimus and corticosteroids and mycophenolate antirejection, the patient discharged 46 days after surgery. 7 articles were retrieved through the search tool, and a total of 8 articles included this case were reported. Five patients who underwent lung transplantation within 1 month after poisoning all died, And 3 patients conducted lung transplantation for more than 1 month after poisoning survived; Pathogenic bacteria were isolated from the sputum in 3 of the 8 cases, all containing Pseudomonas, 2 of which died, and our case survived. Conclusion: Appropriate transplantation time window is very important for the prognosis of paraquat poisoning after lung transplantation. Active treatment of the sputum pathogens, improving the donor receptor matching, and exhausting the various means to remove the paraquat from the storage pool which may improve success rate of lung transplantation.

Abstract
It has been postulated that the direction of HIV transmission between two individuals can be determined by phylogenetic analysis of HIV sequences. This approach may be problematic, since HIV sequences from newly infected individuals are often more similar to index sequences from samples collected years before transmission, compared to those from samples collected at the time of transmission. We evaluated the accuracy of phylogenetic methods for determining the direction of HIV transmission by analyzing next-generation sequencing (NGS) data from index–partner pairs enrolled in the HIV Prevention Trials Network (HPTN) 052 trial. HIV-infected index and HIV-uninfected partner participants were enrolled as serodiscordant couples; samples were analyzed from couples with index-to-partner HIV transmission that was confirmed by genetic linkage studies. NGS for HIV gp41 (HXB2 coordinates: 7691–8374) was performed using plasma samples from thirty-nine index–partner pairs (seventy-eight samples collected within 3 months of partner seroconversion). Maximum likelihood trees were generated using the entire dataset using FastTree v.2. Topological patterns of HIV from each index–partner pair were analyzed. The analysis included 9,368 consensus sequences and 521,145 total sequence reads for the seventy-eight samples analyzed. In 10 per cent (four out of thirty-nine) of couples, the phylogeny was inconsistent with the known direction of transmission. In 26 per cent (ten out of thirty-nine) of couples, the phylogeny results could not discern directionality. In 64 per cent (twenty-five out of thirty-nine) of couples, the results correctly indicated index-to-partner transmission; in two of these twenty-five cases, only one index sequence was closest to the most recent common ancestor. Phylogenetic analysis of NGS data obtained from samples collected within 3 months of transmission correctly determined the direction of transmission in 64 per cent of the cases analyzed. In 36 per cent of the cases, the phylogenetic topology did not support the known direction of infection, and in one-third of these cases the observed topology was opposite to the known direction of transmission. This demonstrates that phylogenetic topology alone may not be sufficient to accurately determine the direction of HIV transmission.

Abstract
Objective:To investigate relationship between the level of estrogen, calcium and phosphorus concentration in serum with benign paroxysmal positional vertigo(BPPV). Method:A total of 84 patients with idiopathic BPPV were enrolled in the experimental group, including 32 non-menopausal women, 24 menopausal women, and 28 males; 83 healthy people without vertigo and vestibular disease were selected as the control group consisted with 32 non-menopausal women, 24 menopausal women and 27 males. The levels of estradiol, serum calcium and serum inorganic phosphorus were measured in all participants. The difference of estrogen level, serum calcium and serum inorganic phosphorus concentration between the experimental group and the control group was analyzed by t test. Result:The total number, age distribution and gender composition of the experimental group and the control group were basically paired, and the age difference was not statistically significant (P=0.71). The overall estrogen level in the experimental group was lower than that in the control group (P<0.01). Among them, the female group's estrogen level, menopausal female estrogen level and male estrogen level in the experimental group were lower than the control group (P<0.01); there was no significant difference in serum calcium and serum inorganic phosphorus concentration between the experimental group and the control group (P=0.55, 0.11, respectively). Conclusion:The decrease of estrogen level may be a risk factor for idiopathic BPPV. The relationship between serum calcium and serum inorganic phosphorus concentration and BPPV needs further study.
