Abstract
Next-generation sequencing (NGS) has laid the foundation for precision oncology care. NGS technologynot only represents an innovation in the methodology but also brings about a revolution in the concept of detecting gene alterations for targeted therapy and immunotherapy of cancers. As basic biomedical research and drug development progress, the landscape of biomarkers associated with gene alterations continues to evolve. Thus, the standardization of NGS-based gene alterations detection should take into account the characteristics of NGS methods and the gene alteration biomarkers. To be specific, whether employed as in vitro diagnostic products or laboratory-developed tests, the detection range can be expanded in response to changes in the clinical evidence level of biomarkers during the process of assay development and clinical application. Such adjustment needs the analytical validation results for supplemented genes or mutant sites within a predefined detection system, which will maximally fulfill the evolving clinical demands in cancer diagnosis and treatment, simultaneously mitigate potential risks effectively. This article primarily discusses the standardization pathway for NGS testing of gene alterations in cancer by focusing on the characteristics of NGS methods, gene alteration biomarkers, and the current status of the standardization of NGS application.

Abstract
Objectives: To investigate the application value of laparoscopic double stapler firings and double stapling technique combined with rectal eversion and total extra-abdominal resection (LDER) in the anal preservation treatment of low rectal cancer. Methods: Inclusion criteria: (1) age was 18-70; (2) the distance of the lower tumor edge from the anal verge was 4-5 cm; (3) primary tumor with a diameter ≤3 cm; (4) preoperative staging of T1~2N1~2M0; (5) "difficult pelvis", defined as ischial tuberosity diameter<10 cm or body mass index>25 kg/m2; (6) patients with strong intention for sphincter preservation; (7) no preoperative treatment (e.g., chemotherapy, radiotherapy, molecular targeted therapy, or immunotherapy); (8) no lateral lymph node enlargement; (9) no previous anorectal surgery; (10) patients with good basic condition who could tolerate surgery. Exclusion criteria: (1) previously suffered from malignant tumors of the digestive tract or currently suffering from malignant tumors out of the digestive tract; (2) patients with preoperative anal dysfunction (Wexner score ≥ 10), or fecal incontinence. The specific surgical steps are as follows: the distal end of the rectum was dissected to the level of the interspace between internal and external sphincters of anal canal. Five centimeters proximal to the tumor, the mesorectum was ligated, and a liner stapler was used to transect the rectum. The distal rectum with the tumor were then everted and extracted through the anus. The rectum was transected 0.5-1.0 cm distal to the tumor with a linear stapler. Full thickness suture was used to reinforce the stump of the rectum, which was then brought back into the pelvic cavity. Finally, an end-to-end anastomosis between the colon and the rectum was performed. A retrospective descriptive study was performed of the clinical and pathological data of 12 patients with T1-T2 stage low rectal cancer treated with LDER at Henan Provincial People's Hospital from January 2020 to December 2022. Results: All 12 patients successfully completed LDER with sphincter preservation, without conversion to open surgery or changes in surgical approach. The median surgical time was 272 (155-320) minutes, with a median bleeding volume of 100 (50-200) mL. No protective stoma was performed, and all patients received R0 resection. The average hospital stay was 9 (7-15) days. There were no postoperative anastomotic leakage or perioperative deaths. All 12 patients received postoperative follow-up, with a median follow-up of 12 months (6-36 months) and a Wexner score of 8 (5-14) at 6 months postoperatively. There was no tumor recurrence or metastasis during the follow-up period. Conclusions: LDER is safe and effective for the treatment of low rectal cancer.

Abstract
OBJECTIVES Overdose prevention centers (OPCs) provide a safe place where people can consume preobtained drugs under supervision so that a life-saving medical response can be provided quickly in the event of an overdose. OPCs are programs that are established in Canada and have recently become legally sanctioned in only a few United States jurisdictions. METHODS We conducted a systematic review that summarizes and identifies gaps of economic evidence on establishing OPCs in North America to guide future expansion of OPCs. RESULTS We included 16 final studies that were evaluated with the Consolidated Health Economic Evaluation Reporting Standards and Drummond checklists. Eight studies reported cost-effectiveness results (eg, cost per overdose avoided or cost per quality-adjusted life-year), with 6 also including cost-benefit; 5 reported only cost-benefit results, and 3 cost offsets. Health outcomes primarily included overdose mortality outcomes or HIV/hepatitis C virus infections averted. Most studies used mathematical modeling and projected OPC outcomes using the experience of a single facility in Vancouver, BC. CONCLUSIONS OPCs were found to be cost-saving or to have favorable cost-effectiveness or cost-benefit ratios across all studies. Future studies should incorporate the experience of OPCs established in various settings and use a greater diversity of modeling designs.

Abstract
Objective: To investigate the safety and efficacy of total pelvic exenteration (TPE) for treating late complications of radiation-induced pelvic injury. Methods: This was a descriptive case series study. The inclusion criteria were as follows: (1) confirmed radiation-induced pelvic injury after radiotherapy for pelvic malignancies; (2) late complications of radiation-induced pelvic injury, such as bleeding, perforation, fistula, and obstruction, involving multiple pelvic organs; (3) TPE recommended by a multidisciplinary team; (4) patient in good preoperative condition and considered fit enough to tolerate TPE; and (5) patient extremely willing to undergo the procedure and accept the associated risks. The exclusion criteria were as follows: (1) preoperative or intraoperative diagnosis of tumor recurrence or metastasis; (2) had only undergone diversion or bypass surgery after laparoscopic exploration; and (3) incomplete medical records. Clinical and follow-up data of patients who had undergone TPE for late complications of radiation-induced pelvic injury between March 2020 and September 2022 at the Sixth Affiliated Hospital of Sun Yat-sen University were analyzed. Perioperative recovery, postoperative complications, perioperative deaths, and quality of life 1 year postoperatively were recorded. Results: The study cohort comprised 14 women, nine of whom had recto-vagino-vesical fistulas, two vesicovaginal fistulas, one ileo-vesical fistula and rectal necrosis, one ileo-vesical and rectovaginal fistulas, and one rectal ulcer and bilateral ureteral stenosis. The mean duration of surgery was 592.1±167.6 minutes and the median blood loss 550 (100-6000) mL. Ten patients underwent intestinal reconstruction, and four the Hartmann procedure. Ten patients underwent urinary reconstruction using Bricker's procedure and 7 underwent pelvic floor reconstruction. The mean postoperative hospital stay was 23.6±14.9 days. Seven patients (7/14) had serious postoperative complications (Clavien-Dindo IIIa to IVb), including surgical site infections in eight, abdominopelvic abscesses in five, pulmonary infections in five, intestinal obstruction in four, and urinary leakage in two. Empty pelvis syndrome (EPS) was diagnosed in five patients, none of whom had undergone pelvic floor reconstruction. Five of the seven patients who had not undergone pelvic floor reconstruction developed EPS, compared with none of those who had undergone pelvic floor reconstruction. One patient with EPS underwent reoperation because of a pelvic abscess, pelvic hemorrhage, and intestinal obstruction. There were no perioperative deaths. During 18.9±10.1 months of follow-up, three patients died, two of renal failure, which was a preoperative comorbidity, and one of COVID-19. The remaining patients had gradual and significant relief of symptoms during follow-up. QLQ-C30 assessment of postoperative quality of life showed gradual improvement in all functional domains and general health at 1, 3, and 6 months postoperatively (all P<0.05). Conclusions: TPE is a feasible procedure for treating late complications of radiation-induced pelvic injury combined with complex pelvic fistulas. TPE is effective in alleviating symptoms and improving quality of life. However, the indications for this procedure should be strictly controlled and the surgery carried out only by experienced surgeons.

Abstract
Objective: To determine the efficacy of eltrombopag for primary immune thrombocytopenia (ITP) in adults and the predictive factors for treatment-free response (TFR) . Methods: Clinical data of adults with ITP who received eltrombopag from June 14, 2013 to May 31, 2021 in the Hematology Department of Ruijin Hospital affiliated with Shanghai Jiao Tong University Medical College were retrospectively analyzed. The initial dose of eltrombopag was 25 mg/d, and the maximum dose was 75 mg/d; the dose was adjusted to maintain the platelet count to within 50-150×10(9)/L. Treatment was discontinued according either to the protocol, on the patient's wishes or doctor's judgment (prescription medication), or based on clinical trials. The efficacy of eltrombopag and factors for TFR among patients who achieved complete response and those who discontinued treatment were analyzed. Results: Overall, 106 patients with ITP (33 men and 73 women) were included in the study. The median age of patients was 50 (18-89) years. There were 2, 10, and 94 cases of newly diagnosed, persistent, and chronic ITP, respectively. The complete response rate was 44.3% (47/106), the response rate was 34.0% (36/106), and the overall response rate was 78.3% (83/106). Meanwhile, 83 patients who responded to treatment discontinued eltrombopag; of these, 81 patients were evaluated. Additionally, 17 patients (21.0%) achieved TFR. The median follow-up duration of patients who achieved TFR was 126 (30-170) weeks. The recurrence rate was 17.6% (3/17), and the relapse-free survival rate was 76.5%. The results of univariate analysis revealed that non-recurrence after discontinuation of other treatments for ITP (P=0.001), and platelet count and eltrombopag dose of ≥100×10(9)/L (P=0.007) and ≤25 mg/d (P=0.031), respectively, upon discontinuation of eltrombopag were predictors of TFR; these effects were attributed to prolonged effective duration of eltrombopag. Multivariate analysis showed that there was a correlation between non-recurrence and prolonged effective duration after discontinuation of other treatments for ITP (P=0.002) . Conclusion: Eltrombopag is effective for patients with ITP as it can result in TFR. Predictors for TFR include non-recurrence after discontinuation of concomitant ITP treatment, and platelet count and eltrombopag dose of ≥100 × 10(9)/L and ≤25 mg/d upon discontinuation of treatment, respectively.

Abstract
We present improved germanium-based constraints on sub-GeV dark matter via dark matter-electron (χ-e) scattering using the 205.4 kg·day dataset from the CDEX-10 experiment. Using a novel calculation technique, we attain predicted χ-e scattering spectra observable in high-purity germanium detectors. In the heavy mediator scenario, our results achieve 3 orders of magnitude of improvement for m_{χ} larger than 80 MeV/c^{2} compared to previous germanium-based χ-e results. We also present the most stringent χ-e cross-section limit to date among experiments using solid-state detectors for m_{χ} larger than 90 MeV/c^{2} with heavy mediators and m_{χ} larger than 100 MeV/c^{2} with electric dipole coupling. The result proves the feasibility and demonstrates the vast potential of a new χ-e detection method with high-purity germanium detectors in ultralow radioactive background.

Abstract
A search for exotic dark matter (DM) in the sub-GeV mass range has been conducted using 205 kg day data taken from a p-type point contact germanium detector of the CDEX-10 experiment at China's Jinping underground laboratory. New low-mass dark matter searching channels, neutral current fermionic DM absorption (χ+A→ν+A) and DM-nucleus 3→2 scattering (χ+χ+A→ϕ+A), have been analyzed with an energy threshold of 160 eVee. No significant signal was found; thus new limits on the DM-nucleon interaction cross section are set for both models at the sub-GeV DM mass region. A cross section limit for the fermionic DM absorption is set to be 2.5×10^{-46} cm^{2} (90% C.L.) at DM mass of 10 MeV/c^{2}. For the DM-nucleus 3→2 scattering scenario, limits are extended to DM mass of 5 and 14 MeV/c^{2} for the massless dark photon and bound DM final state, respectively.

Abstract
Technical Specifications for Occupational Health Surveillance (GBZ 188-2014) is an important basis for judging suspected occupational diseases and occupational contraindications. There are crossing over or overlap between occupational contraindications and diagnostic criteria of poisoning damage. Occupational contraindications have different meanings with the degree and range of common diseases or symptoms and the frequency of physical examination during employment conflicts with the current standard. Based on the practice of occupational health examination in a large population, the present study analyzed relevant articles and put forward some suggestions for revision, in combination with clinical medicine, occupational health standards, and diagnostic standards of occupational diseases. The modification could provide a reference for the revision of Technical Specifications for Occupational Health Surveillance and the practice of occupational health examination.

Abstract
Objective: To investigate the diagnostic efficiency and incremental value of quantitative myocardial blood flow measurements by Cadmium-Zine-Telluride (CZT) single photon emission computed tomography (SPECT) dynamic myocardial perfusion imaging (MPI) in patients with coronary artery disease (CAD) compared with traditional semi-quantitative measurements by MPI. Methods: This is a retrospective, cross-sectional study. We retrospectively analyzed clinical data of patients with suspected or known CAD, who underwent the dynamic MPI quantitative blood flow measurement of CZT SPECT in TEDA International Cardiovascular Hospital from October 2018 to December 2020. Clinical data, semi-quantitative parameters (stress score (SS), rest score (RS) and different score (DS)) and myocardial quantitative blood flow parameters (rest myocardial blood flow (rMBF), stress myocardial blood flow (sMBF) and myocardial flow reserve (MFR)) were analyzed. According to the results of coronary angiography, patients were divided into the stenosis group and the control group with coronary artery stenosis ≥50% or ≥75% as the diagnosis criteria. The differences of quantitative and semi-quantitative parameters between the two groups were compared, and the diagnostic efficacy was compared by receiver operating characteristic(ROC) curve. Results: A total of 98 patients with a mean age of (62.1±8.7) years were included in the study, including 66 males (67%). At the patient level, with the positive standard of coronary artery stenosis≥50%, the left ventricle (LV) stress MBF (LV-sMBF) ((1.36±0.45) ml·min-1·g-1) and LV-MFR (1.45±0.43) of the stenosis group were lower than the LV-sMBF ((2.09±0.64) ml·min-1·g-1) and LV-MFR (2.17±0.54) of control group; summed SS and summed DS were higher than control group (all P<0.05). With the positive standard of coronary artery stenosis ≥75%, the LV-sMBF ((1.19±0.34) ml·min-1·g-1) and LV-MFR (1.34±0.35) of stenosis group were lower than the LV-sMBF ((1.94±0.63) ml·min-1·g-1) and MFR (2.00±0.58) of control group; all semi-quantitative parameters were higher than control group (all P<0.05). At the vascular level, with coronary artery stenosis ≥50% as the diagnosis criteria, the sMBF ((1.26±0.49) ml·min-1·g-1) and MFR (1.35±0.46) of stenosis group were lower than the sMBF ((1.95±0.70) ml·min-1·g-1) and MFR (2.05±0.65) of control group; SS and DS were higher than control group (all P<0.05). With coronary artery stenosis≥75% as the diagnosis criteria, the sMBF ((1.12±0.41) ml·min-1·g-1) and MFR (1.25±0.38) of stenosis group were lower than the sMBF ((1.84±0.70) ml·min-1·g-1) and MFR (1.93±0.66) of control group; all semi-quantitative parameters were higher than control group (all P<0.05). With coronary artery stenosis≥50% as the diagnosis criteria and CAG as the reference standard, the AUC and 95%CI of myocardial quantitative blood flow parameters indicated by ROC curve for diagnosis of CAD were 0.830 (0.783-0.877). The sensitivity (86.1% vs. 61.5%), specificity (82.6% vs. 73.8%), positive predictive value (77.8% vs. 62.5%), negative predictive value (89.3% vs. 73.0%) and accuracy (84.0% vs. 68.7%) were all higher than the semi-quantitative parameters (all P<0.05). With coronary artery stenosis≥75% as the diagnosis criteria, the AUC and 95%CI of myocardial quantitative blood flow parameters indicated by ROC curve for diagnosis of CAD were 0.832(0.785-0.879). The sensitivity (89.2% vs. 67.6%), negative predictive value (95.5% vs. 86.2%) and accuracy (80.6% vs. 68.0%) were all higher than semi-quantitative parameters (all P<0.05). Conclusion: Compared with traditional SPECT MPI derived semi-quantitative parameters, diagnostic efficacy for CAD is higher using CZT SPECT quantitative myocardial blood flow parameters, this strategy thus has additional diagnostic benefits and incremental value on the diagnosis of CAD.

Abstract
Telemedicine, which integrates medicine, communication, engineering, information and other disciplines, is a hot emerging cross field in recent years. With the development of telecommunication technology and surgical robot, telesurgery is regarded as the "crown pearl" in telemedicine and has attracted more and more attention. As an extension of traditional surgery, telesurgery greatly extends the connotation and concept of surgery and embodies the great leap forward development of surgical technology. Despite the current limitations such as network delay, transparency of remote robot operation and team construction of surgeons, telesurgery has still formed a variety of innovative application scenarios and achieved rapid development in China in recent years. In view of the uneven distribution of medical resources in China and the epidemic of COVID-19 in the world, this paper puts forward the possible problems and solutions in the development of telesurgery, and looks forward to the feasibility of telesurgery technology in process of shifting the focus of medical and health care down to the community level, channeling resources accordingly.

Abstract
Objective: To investigate the methods and quality assurance of metagenomic next-generation sequencing (mNGS) to detect the microbial cfDNA (mcfDNA) from blood samples in different laboratories across China. Methods: In October 2020, questionnaires about detecting mcfDNA in blood samples with mNGS were distributed to 80 laboratories across the country. The questionnaire included four parts: pre-analysis, during analysis, post-analysis, and carrying out of performance validation for mNGS. (1) Pre-analysis: the requirements for samples quality, such as collection, storage, the transportation conditions of samples; (2) During analysis: the extraction workflows of mcfDNA, the quality requirements of the library, the application of the sequencing platforms and the bioinformatics analysis pipelines; (3) Post-analysis: the standard of interpretation results for mNGS; (4) Carrying out of performance validation: the minimum detection limit for various pathogens. All laboratories are required to fill in the questionnaire according to the actual situation. The feedback data were summarized and analyzed. Results: The 80 laboratories included 20 medical centers and 60 independent medical laboratories. There were 80.0% (64/80) of laboratories indicated that both plasma and serum samples were used to detect mcfDNA in blood, and the rest of the laboratories (16/80, 20.0%) only used plasma samples. The sequencing platforms used by mNGS laboratories involved in the survey included illumina (49), Beijing Genomics Institute (16), Ion Torrent (13) and Nanopore sequencing (2). There were 87.5% (70/80) of laboratories used the integrated analysis tools built by the third-party laboratories, and other laboratories (12.5%, 10/80) independently built the analysis platform by open-source software. The interpretation criteria of mNGS results varied between laboratories, among which the normalized number of pathogen-specific sequences, relative abundance, genome coverage rate, and the detection of the microorganism in the negative control were the main factors considered by laboratories. Most laboratories (76.3%, 61/80) had carried out the performance validation for the mcfDNA mNGS workflows. The limit of detection of the laboratories-developed mNGS workflows for Gram-positive bacteria, Gram-negative bacteria, fungi, parasites, and other pathogens were mainly distributed at 10-100 copies/ml, DNA virus was mainly distributed at 500-1 000 copies/ml. Conclusions: The mNGS workflows of various laboratories are very different. In order to ensure timely and accurate testing results, every laboratory needs to actively optimize the mNGS testing procedures, improve quality assurance measures, and carry out performance validation before mNGS is widely used in clinical settings.

Abstract
The knowledge of high-pressure behavior of LiH is significant for the validation of fundamental theoretical models and applications in thermonuclear materials and potential energy supplies. The compressibility of 7LiH under isentropic compression at high pressure was investigated experimentally and theoretically. The experimental technique for quasi-isentropic compression with low-density materials was developed using the magnetocumulative generator CJ-100 and x-ray flash radiography. The x-ray images and extracted interface of the sample target in dynamic flash radiography experiments were obtained. According to each interface size of the target both before and after compression, the compression ratio of 7LiH and reference material aluminum was obtained. The density of the reference and using its known isentropic curve provide the pressure in the reference. The pressure in 7LiH was deduced from the pressure in the reference and using the calculated gradient correction factor. The quasi-isentropic data point at 438 GPa was obtained experimentally. A semiempirical three-term complete equation of state was constructed and validated for 7LiH using the theory of Mie-Grüneisen-Debye with experimental data from the literature. The quasi-isentrope data point is reasonably consistent with the theoretical results. The quasi-isentropic experimental techniques and results broaden the existing research scope and are practical and helpful to further validate theoretical models in the future.

Abstract
Objective: To explore the expression of long non-coding RNA-myeloid differentiation factor 88 (lnc-MyD88) and its relationship with the prognosis of patients with epithelial ovarian cancer (EOC). Methods: A total of 70 EOC patients who underwent initial cytoreductive surgery and platinum-based drugs combined with paclitaxel for 6 to 8 courses were selected at Sichuan Cancer Hospital from January 2016 to January 2019. The fresh cancer tissue specimens were collected. In addition, 28 fresh normal ovarian tissues from patients who underwent surgery for benign gynecological diseases during the same period were collected as control group. Reverse transcription (RT) and real-time quantitative polymerase chain reaction (qPCR) were used to detect the expression of lnc-MyD88 and myeloid differentiation factor 88 (MyD88) mRNA in EOC tissues and normal ovarian tissues. The correlation between the expression of lnc-MyD88 and MyD88 mRNA in EOC was analyzed by Pearson's correlation coefficient. The relationship between lnc-MyD88 expression and clinicopathological characteristics of patients with EOC was analyzed. Kaplan-Meier method was used to calculate the survival rate of patients. The log-rank test was used for univariate survival analysis, and Cox proportional hazard model was used for multivariate survival analysis. Results: (1) RT-qPCR showed that the relative expression level of lnc-MyD88 and MyD88 mRNA in EOC were 0.009 (0.000-0.049) and 0.001 (0.000-0.006), respectively, which were significantly higher than those of normal ovarian tissues (all P<0.01); Pearson's correlation coefficient showed that the expression of lnc-MyD88 and MyD88 mRNA in EOC was positively correlated (r2=0.610, P<0.01). (2) The high expression rate of lnc-MyD88 in EOC patients with lymph node metastasis, distant metastasis and chemotherapy resistance (71%, 64% and 70%, respectively) were significantly higher than the patients in control group (41%, 40% and 35%, respectively; all P<0.05). There were no statistically significant in the high expression rate of lnc-MyD88 in EOC patients with different ages, pathological types, pathological grades, surgical pathological stages, postoperative residual lesion size, and ascites cancer cells (all P>0.05). (3) Univariate analysis showed that surgical pathological staging, lymph node metastasis, distant metastasis, postoperative residual tumor size, and high expression of lnc-MyD88 and MyD88 mRNA significantly affected the progression-free survival (PFS) and overall survival (OS) of EOC patients (all P<0.05), ascites cancer cells were the risk factors that significantly affected PFS in EOC patients (P=0.040); multivariate analysis showed that surgical pathological staging and high expression of lnc-MyD88 and MyD88 mRNA were independent factors affecting PFS and OS in EOC patients (all P<0.05), the size of residual lesions after surgery was an independent factor affecting PFS in EOC patients (P=0.001). Conclusions: The level of lnc-MyD88 expression in ovarian cancer tissues was significantly increased. Lnc-MyD88, as a molecular marker for the poor prognosis of EOC, is related to the expression of MyD88 in EOC, and may be involved in its expression regulation, thereby affecting the survival and prognosis of EOC patients.

Abstract
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired hematopoietic stem cell disease. Gastrointestinal involvement is rarely seen in PNH. This study aims to analyze the clinical features in PNH patients complicated with ischemic bowel disease. Clinical date of 6 patients were collected at Peking Union Medical College Hospital from January 2010 to December 2020. The clinical manifestations, laboratory tests,imaging, endoscopic,and histopathological features and treatment were analyzed.Five in 6 patients were men, with a median age of 31 years old at onset. Most of disease course were recurrent episodes of chronic disease, with abdominal pain (5/6) and gastrointestinal bleeding (5/6). Laboratory examinations showed pancytopenia, reticulocytosis, elevated serum lactate dehydrogenase, high D-dimer and C-reactive protein levels in all patients. Multiple segments of small intestine were the most commonly involved and colon was also affected. Abdominal CT scan showed thickening and roughness or exudation of the intestinal wall (6/6), increased mesenteric density or "comb sign"(4/6), and cholestasis or gallbladder stones (5/6). Endoscopic manifestations included irregular shallow ulcers in the annular cavity (5/6), swelling mucosa with well-defined margins (6/6). Pathological biopsy revealed chronic inflammation of mucosa. The efficacy of steroids combined with anticoagulant therapy was better than that of steroids alone. Ischemic bowel disease in PNH patients is different from typical ischemic enteritis. Young patients, involvement of intestine with multiple segments are common characteristics. The anticoagulant is an essential agent for these patients.

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
Wernekinck commissure syndrome is a rare midbrain infarction, it consists of several symptoms including bilateral cerebellar ataxia, ophthalmoplegia, and palatal tremor. Holmes tremor is a rare clinical syndrome characterized by a combination of resting, postural, and action tremors. We describe two cases of Wernekinck commissure syndrome with Holmes tremor. To the best of our knowledge, it has been rarely reported in the literature to date. Both of the cases were presented with acute onset of bilateral cerebellar ataxia, dysarthria, and Holmes tremor. In the treatment, one patient was given "clonazepam and benheisol," the other was received acupuncture therapy, both of them showed a marked improvement in ataxia and tremor.

Abstract
Objective: To evaluate the value of next generation sequencing (NGS) in the genetic testing of Lynch syndrome. Methods: Immunohistochemical method was used to detect the expressions of DNA mismatch repair (MMR) proteins, including MutL homolog 1 (MLH1), PMS1 homolog 2 (PMS2), MutS homolog 2 (MSH2) and MutS homolog 6 (MSH6) in colorectal cancer, gastric cancer and endometrial cancer tissues collected from Shandong Provincial Hospital between 2016 and 2018. The genomic DNA of 45 patients who were suspected with Lynch syndrome was extracted from non-cancerous tissue paraffin samples, which were postoperatively confirmed by microscope. The mutations of 12 genes including MLH1 and MSH2 were detected using NGS. The germline mutant sites and significance were analyzed by bioinformatics technology and further confirmed by using Sanger sequencing. Results: The immunohistochemical results showed that the 45 cases of suspected Lynch syndrome included 22 cases of MLH1 and PMS2 deficient expression, 16 cases of MLH2 and MSH6 deficient expression, and 7 cases of MMR proteins normal expression. The NGS result showed that 28 cases of adjacent sample from colon cancer patients included 4 cases of MLH1 pathogenic mutation, 1 case of suspected MLH1 mutation, 2 cases of MLH2 pathogenic mutation, 2 cases of suspected MLH2 mutation. No MMR gene mutation was found in adjacent samples of 6 cases of rectal cancer, 6 cases of gastric cancer and 7 cases of colorectal cancer with MMR normal expression. One case of MLH1 or MHL2 pathogenic mutation and one case of MLH1 suspected mutation was detected in adjacent samples of 5 cases of endometrial cancer. Moreover, NGS also detected many other genes mutations and unreported gene mutation sites. Pathogenic and suspected MLH1 and MSH2 mutations were verified by Sanger sequencing. Conclusions: High-throughput NGS is a quick, accurate and reliable technique to identify gene variants in suspected Lynch syndrome patients. It has a wide application prospect for gene testing of tumors associated with Lynch syndrome.

Abstract
Objective: To explore the effect of protein disulfide isomerase (PDI) in diabetic ischemic heart disease. Methods: We established an in vitro model of high glucose and hypoxia/reoxygenation in H9c2 rat myocardial cells. Cultured cells were divided into four groups: Control, high glucose (HG), hypoxia/reoxygenation (H/R) and HG+H/R. Changes in PDI expression mediated by PDI adenovirus(Ad-PDI) infection and siRNA(PDI-siRNA) transfection in myocardial cells were observed by inverted fluorescence microscopy. We also measured lactate dehydrogenase(LDH) activity and malondialdehyde(MDA) and high molecular weight(HMW)-APN concentrations. PDI, APN, cleaved caspase-3, and glucose regulated protein 78 (Grp78) protein expression were detected. Results: PDI expression was significantly decreased in the HG, H/R and HG+H/R groups compared to the Control group; however, LDH activity[(179.7±10.4) U/L、(218.4±18.4) U/L、(328.2±5.3) U/L vs (91.0±11.0) U/L], MDA concentration[(7.0±0.4) μmol/L、(10.0±1.0) μmol/L、(11.7±1.0) μmol/L vs (4.2±1.8) μmol/L], cleaved caspase-3, and Grp78 expression were increased. Interestingly, APN and HMW-APN expression were decreased [(2.01±0.21) μg/L、(1.64±0.27) μg/L、(1.20±0.14) μg/L vs (2.62±0.12) μg/L, all P<0.05]. Over expression of PDI attenuated high glucose and hypoxia/reoxygenation induced apoptosis and oxidative stress in H9c2 cardiomyocytes(all P<0.05), and simultaneously increased APN and HMW-APN expression [(2.86±0.03) μg/L vs (3.03±0.10) μg/L、(2.06±0.05) μg/L vs (2.31±0.06) μg/L、(1.83±0.07) μg/L vs (1.96±0.11) μg/L、(1.20±0.06) μg/L vs (1.39±0.09) μg/L]. PDI-siRNA transfection increased LDH activity, MDA concentration, and cleaved caspase-3 and Grp78 expression, and decreased APN and HMW-APN expression [(0.75±0.09) μg/L vs (0.59±0.09) μg/L、(0.62±0.04) μg/L vs (0.53±0.05) μg/L、(0.55±0.14) μg/L vs (0.51±0.12) μg/L、(0.48±0.12) μg/L vs (0.35±0.08) μg/L] in response to different treatments in cultured H9c2 cardiomyocytes (all P<0.05). Conclusion: PDI may regulate the expression of APN and HMW-APN, and play an important role in the function of diabetic ischemia-reperfusion cardiomyocytes.

Abstract
Objective: To investigate the effect of circBANP on radiosensitivity of colorectal cancer cells and subcutaneous transplanted tumor in nude mice and its potential molecular mechanism. Methods: The carcinoma and adjacent normal mucosal tissues of 20 patients with colorectal cancer who were surgically resected in Henan People's Hospital from January 2018 to January 2019 were selected. The radio-resistant colorectal cancer cell LoVo/R was established. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the expressions of circBANP and miR-338-3p. The radiation sensitivity was determined by cell clone formation experiment. Cell vitality was detected by using methyl thiazolyl tetrazolium (MTT). The expressions of autophagy-related protein microtubule-associated protein light chain 3 (LC3) and p62 were detected by western blot. The fluorescence intensity of LC3 in cells was detected by immunofluorescence assay. The downstream microRNAs (miRNAs) of circBANP were predicted by Circular RNA Interactome website and further verified by dual luciferase reporter gene assay. The transplanted tumor model of LoVo/R cells in nude mice was established, and the effect of circBANP on the growth of transplanted tumor after radiation was observed. Results: The expression levels of circBANP and miR-338-3p in colorectal cancer tissues were 3.21+ 0.29 and 0.47+ 0.04, respectively, which were significantly higher than 1.00+ 0.07 and 1.00+ 0.05 in adjacent tissues (P<0.05). The circBANP expression level of LoVo/R cells was 3.21±0.34, higher than 1.00±0.07 of LoVo cells (P<0.05), and the expression level of miR-338-3p of LoVo/R cells was 0.33±0.04, lower than 1.00±0.08 of LoVo cells (P<0.05). After 4 Gy irradiation, compared with the control group, the viability of LoVo/R cells in the circBANP silencing group [(34±4)% vs (62±6)%, P<0.05], the cell survival fraction (0.07±0.02 vs 0.27±0.04, P<0.05) were decreased, and the radiation sensitization ratio was 1.843, the expression of LC3Ⅱ/Ⅰin LoVo/R cells increased while p62 expression decreased, the cell autophagy was observed. Autophagy inhibitor chloroquine reversed the increased expression of LC3Ⅱ/Ⅰ and inhibited expression of p62 in LoVo/R cells induced by radiation, and promoted the suppression of cell viability and survival induced by radiation, the radiotherapy sensitization ratio was 1.780. Compared with control group after 4 Gy irradiation, the relative fluorescence intensity of LC3 in circBANP silencing LoVo/R cells decreased (0.11±0.01 vs 1.00±0.12, P<0.05), the expression of LC3-Ⅱ/Ⅰdecreased (1.25±0.13 vs 3.84±0.39, P<0.05) while p62 expression increased (2.76±0.29 vs 1.00±0.08, P<0.05). As predicted by Circular RNA Interactome website and confirmed by double luciferase reporter gene assay, miR-338-3p was the target gene of circBANP. The relative fluorescence intensity of LC3 in circBANP silencing + anti-miR-338-3p + 4 Gy group increased (7.32±0.72 vs 1.00±0.09, P<0.05), the expression level of LC3-Ⅱ/Ⅰ increased (4.13±0.43 vs 2.31±0.23, P<0.05) while p62 expression decreased (0.34±0.03 and 1.00±0.11, P<0.05), the radiotherapy sensitization ratio was 0.596. Nude mice subcutaneously transplanted tumor experiment showed that the tumor volume and weight of circBANP silencing group on 13, 16, 19, 22, 25, 28, and 31 days were lower than those of control group (P<0.05), while the tumor volume and weight of circBANP silencing + anti-miR-338-3p group on days of 13, 16, 19, 22, 25, 28 and 31 after inoculated were higher than those of circBANP+ anti-miR-NC group (P<0.05). Conclusions: CircBANP can regulate the radiosensitivity of colorectal cancer cells by regulating the expression of miR-338-3p, and affect the growth of transplanted tumor in nude mice. CircBANP may be a potential target for enhancing radiosensitivity of colorectal cancer cells.

Abstract
Objective: To investigate the safety and efficacy of venetoclax with low-dose cytarabine (LDAC) in Chinese patients with acute myeloid leukemia (AML) who are unable to tolerate intensive induction chemotherapy. Methods: Adults ≥ 18 years with newly diagnosed AML who were ineligible for intensive chemotherapy were enrolled in this international, randomized, double-blind, placebo-controlled trial. Globally, patients (n=211) were randomized 2∶1 to either venetoclax with LDAC or placebo with LDAC in 28-d cycles, with LDAC on days 1-10. The primary endpoint was OS; the secondary endpoints included response rates, event-free survival, and adverse events. Results: A total of 15 Chinese patients were enrolled (venetoclax arm, n=9; placebo arm, n=6) . The median age was 72 years (range, 61-86) . For the primary analysis, the venetoclax arm provided a 38% reduction in death risk compared with the placebo[hazard ratio (HR) , 0.62 (95%CI 0.12-3.07) ]. An unplanned analysis with an additional 6 months of follow-up demonstrated a median OS of 9.0 months for venetoclax compared with 4.1 months for placebo. The complete remission (CR) rates with CR with incomplete blood count recovery (CRi) were 3/9 (33%) and 0/6 (0%) , respectively. The most common non-hematologic adverse effects (venetoclax vs placebo) were hypokalemia[5/9 (56%) vs 4/6 (67%) ], vomiting[4/9 (44%) vs 3/6 (50%) ], constipation[2/9 (22%) vs 4/6 (67%) ], and hypoalbuminemia[1/9 (11%) vs 4/6 (67%) ]. Conclusion: Venetoclax with LDAC demonstrated meaningful efficacy and a manageable safety profile in Chinese patients consistent with the observations from the global VIALE-C population, making it an important treatment option for patients with newly diagnosed AML who are otherwise ineligible for intensive chemotherapy.

Abstract
Objective: To investigate the expression of circular ribonucleic acid ABCB10 (circABCB10) in colorectal cancer tissues and cells and its effects on cell biological behavior, radiosensitivity and growth of subcutaneous xenografts. Methods: The tumor tissue and adjacent tissue from colorectal cancer patients treated in Henan People's Hospital were collected from January 2018 to December 2018. Quantitative polymerase chain reaction (qPCR) was used to detect the expressions of circABCB10 and miR-217, cell viability was detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H tetrazolium bromide (MTT), cell apoptosis rate was detected by flow cytometry, cell migration and invasion were detected by Transwell method, cell radiosensitivity was detected by colony formation assay. The downstream miRNAs of circABCB10 were predicted by Circular RNA Interactome and verified by the dual luciferase reporter gene experiment. The effect of circABCB10 on the growth of transplanted tumor was examined in nude mice. Results: The expression level of circABCB10 mRNA in colorectal cancer tissues was (3.97±2.12), higher than (1.13±0.64) in adjacent tissues (P<0.05). The expression level of circABCB10 mRNA in FHC cells was (1.00±0.09), lower than that (4.53±0.44) in SW480, (3.12±0.32) in HCT116 and (3.51±0.36) in HT29 cells, respectively (all P<0.05). The MTT results showed that the absorbance values of SW480 cells in si-circABCB10-1 group at 48 and 72 hours after transfection were (0.36±0.04) and (0.43±0.04), lower than (0.48±0.05) and (0.82±0.08) in circ-negative control (NC) group, respectively (all P<0.05). The number of migrating cells and invasive cells in si-circABCB10-1 group were (45±8) and (34±7), lower than (106±21) and (84±15) in circ-NC group, respectively (all P<0.01). The radiosensitization ratio was 1.632. The results of subcutaneous transplantation assay showed that the tumor volume and tumor weight of the si-circABCB10-1 group were significantly lower than circ-NC group after 8 days of inoculation ( all P<0.05). MiR-217 is a target gene of circABCB10. Inhibition of miR-217 reversed the inhibitory effect of circABCB10 silencing on cell proliferation, migration, invasion and subcutaneous xenograft growth in nude mice and the radiosensitization activity. Conclusion: Silence of circABCB10 can up-regulate the expression of miR-217 to inhibit the proliferation, migration, invasion and growth of subcutaneous xenografts and increase the radiosensitivity of SW480 cells, which reveals the underlying molecular mechanism of colorectal cancer progression and provides a new sensitizing target for clinical radiotherapy of colorectal cancer.

Abstract
Objective: To investigate the general situation, detection range, testing reagents, and clinical performance of non-invasive prenatal testing (NIPT) for fetal chromosomal copy number variations (CNVs) in Chinese laboratories. Methods: The National Center for Clinical Laboratories of the National Health Commission designed a questionnaire for the detection of CNVs by NIPT, which included the investigation of whether the laboratory has carried out NIPT to detect CNVs and its testing scope, reagents/platforms, intended uses, screening populations and clinical performance. The questionnaires were distributed to 355 laboratories in 31 provinces, autonomous regions, and municipalities across the country on October, 2020. Further, the feedbacks were statistical analyzed. Results: Two hundred and twenty-eight laboratories had performed NIPT to detect CNVs, including 116 types of CNVs, and more than 95% of laboratories chose to detect the CNVs of 5p15 deletion, 22q11.2 deletion, 1p36 deletion, and 15q11.2 deletion. All testing reagents used were laboratory-developed tests and were based on massive parallel sequencing, the minimum amount of sequencing data was 3-15 M reads, the detection limit of fetal fraction was 3%-5%, and the minimum size of variants that can be detected was 1-5 Mb. The proportion of laboratories that apply CNVs testing for daily project, voluntary requirements of patients, and scientific research were 58.8% (134/228), 57.5% (131/228), and 20.6% (47/228), respectively. One hundred and thirty-four laboratories were fully or partially aware of the clinical performance of NIPT to detect microdeletion/microduplication syndromes, and the laboratories' declared sensitivity of NIPT for Cri du Chat syndrome, 22q11.2 deletion syndrome, 1p36 deletion syndrome, and Angelman syndrome were 50.0%-100%, 60.0%-100%, 50.0%-100%, and 33.3%-100%, and the positive predictive values were 9.0%-50.0%, 18.0%-100%, 20.0%-30.0%, and 20.0%. Conclusion: The detection of CNVs by NIPT in Chinese laboratories need to be standardized. Laboratories should detect CNVs with clear clinical significance in accordance with the guidelines, conduct performance validation of the reagents, then perform NIPT test and provide adequate interpretation after mastering the clinical performance sufficiently.

Abstract
There has consistently growing value of molecular detection to deliver clinical results for diagnosis, classification, prognosis, curative effect prediction and monitoring minimal residual disease of hematological neoplasms. Currently, some clinical laboratories are adopting hematological neoplasms-associated molecular detection in in our country. The increasing demands for clinical testing require that the particular attention need to be paid to the building of the team of professional staff. At present, it is vital to cultivate two kinds of specialized personnel: the technical personnel who are educated in clinical medicine and skilled in developing molecular tests; and the trained managers who are adept at quality control for molecular testing.

Abstract
Objective: To explore the related factors of the coronary microvascular disease (CMD) diagnosed with positron emission tomography(PET)/CT in patients with chest pain and without obstructive coronary artery disease (NOCA). Methods: This study was a single-center retrospective cross-sectional study. Consecutive patients with chest pain and NOCA on coronary angiography, who underwent PET/CT quantitative myocardial blood flow measurements at TEDA International Cardiovascular Hospital from August 2018 to January 2019, were enrolled for this study. The diagnostic criteria for NOCA was the absence of coronary artery diameter stenosis ≥50% on coronary angiography. Clinical data, global left ventricular myocardial blood flow on stress and rest, and the coronary flow reserve (CFR) were analyzed. Patients were divided into two groups according to CFR. Patients with CFR<2 were defined as CMD group, and the rest were classified as control group. Pearson correlation analysis and Logistics regression analysis were used for exploring the risk factors of the CMD. Results: A total of 66 patients, with an mean age of (56.7±9.6) years, were included in the study, including 41 females (62%). There were 20 patients with CMD (30%). Body mass index (BMI) was significantly higher in CND group than in control group ((28.1±3.6) kg/m2 vs. (25.6±3.5) kg/m2, P=0.01). Total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) were also significantly higher in CMD group than in control group ((4.89±1.03) mmol/L vs. (4.30±1.02) mmol/L and (3.23±0.81) mmol/L vs. (2.71±0.95) mmol/L respectively, P=0.038). Pearson correlation analysis showed that CFR was moderately correlated with BMI (r=-0.45, P<0.001), and was weakly correlated with TC and LDL-C (r=-0.271 and r=-0.280, respectively, P<0.05). Multivariate logistic regression analysis showed that BMI (the risk of CMD increased by 1.528 times for every 5 kg/m2 increase in BMI, 95%CI 1.083-5.897, P<0.05) was an independent risk factor of CMD after adjusted by gender, hypertension, diabetic mellites and LDL-C. Conclusion: For patients with NOCA and chest pain, high BMI is independent risk factor of CMD diagnosed by PET/CT.

Abstract
Objective: To investigate the effect and mechanism of exosome-derived miR-223 from macrophage on gastric cancer (GC) cell metastasis. Methods: Exosomes isolated from macrophages culture medium were characterized and cocultured with GC cell, the miRNA level was detected by qRT-PCR. The migration and invasion of GC cell were detected by transwell. The internalization of exosomes, transfer of miR-223 was observed by immunofluorescence. Macrophage were transfected with a miR-223 inhibitor or negative control, transwell and scratch test were employed to explore the effect of macrophage derived exosome on the migration and invasion of GC cell. Western blot and RT-PCR assay were performed to uncover the underlying mechanisms of miR-223 and PTEN-PI3K/AKT pathway. Results: This study showed that macrophage and macrophage-derived exosomes promoted the migration and invasion of gastric cancer cell(253.2±6.3, 451.8±12.8, 453.4±14.4, all P<0.01, and 98.4±5.1, 276.5±10.3, 257.3±8.5, all P<0.01, respectively). miR-223 was enriched in macrophage-derived exosomes, which was transferred to the co-cultivated gastric cancer cells. miR-223 knockdown in macrophage reversed the migration and invasion of exosomes on gastric cancer cells(215.6±9.2, 402.5±11.6, 253.7±10.4, all P<0.01, and 91.5±8.2,263.4±9.3,105.8±9.3,all P<0.01, respectively).Functional studies revealed that exosomal miR-223 derived from macrophage promoted the metastasis of GC cells via the PTEN-PI3K/AKT pathway. In addition, itshowed thatthe actin cytoskeleton was altered, and multiple proteins associated with epithelial-mesenchymaltransition (EMT) were upregulated. Conclusion: Exosomal transfer of macrophage-derived miR-223 promote the metastasis of GC cells through targeting the PTEN-PI3K/AKT pathway.

Abstract
Objective: To analyze the differences of clinical characteristics and outcomes between relapsing and monophasic patients with anti-leucine-rich glioma-inactivated 1 (anti-LGI1) encephalitis. Methods: Medical records of confirmed anti-LGI1 encephalitic patients who underwent immunotherapy were retrospectively collected from January 2015 to January 2019 in the first affiliated hospital of Zhengzhou University. Clinical data, treatment methods, duration of treatment and outcomes were analyzed between the relapsing and monophasic groups. Results: Among the 33 anti-LGI1 encephalitic patients, there were 12 and 21 cases in the relapsing and monophasic groups, respectively. No difference was found in age, sex, precipitating factors, intensive care unit (ICU) admission, symptoms and modified Rankin Scale (mRS) score in the acute phase (P>0.05). As to the lab test and image examination, no statistic difference was found in serum and cerebral spinal fluid (CSF) positive rate, hyponatremia, abnormal rate of electrocardiogram (ECG), electroencephalogram (EEG), CSF and magnetic resonance imaging (MRI) and lesion locations (P>0.05). No difference was found in time to diagnose the disease between the 2 groups (P>0.05). The median immunotherapy period was 102.5 days in relapsing group and 194.0 days in monophasic group, with a statistic difference (P=0.001). No patients had bad outcomes in the monophasic group at the last follow-up, while 6 patients had poor outcomes in the relapsing group (4 patients died). The patients in relapsing group had a worse prognosis compared to those in the monophasic group (P=0.007). Conclusions: Relapse is common in anti-LGI1 encephalitis. Patients in the relapsing group received a shorter term of immunotherapy and had worse outcomes than those in the monophasic group.

Abstract
Objective: To understand the characteristics of clusters of COVID-19 cases in Tianjin, and provide epidemiological evidence for the prevention and control of COVID-19. Methods: The data of all the COVID-19 cluster cases in Tianjin, reported by 22 February 2020, were collected to analyze the characteristics of different types of the clusters. Results: A total of 115 COVID-19 cases were reported in 33 clusters in Tianjin included 28 family clusters (71 cases), 1 work place cluster (10 cases), 3 transport vehicle clusters (8 cases) and 1 public place cluster (26 cases). Family clusters were caused by the cases from the working place or public place clusters. Numbers of secondary cases of family clusters was between 1 to 7, the median number was 2. The interval from onset to diagnosis for the first case was longer than those of other cases in the familial clusters (Z=-2.406, P=0.016). The median of incubation period of the public place clusters was 2 days. The intervals from onset to diagnosis were significant different among the family, working place and public place clusters (H=8.843, P=0.012), and also significant differences in onset time among the secondary cases (H=16.607, P=0.000). Conclusions: In the surveillance of COVID-19 epidemic, special attention should be paid to places where clustering are prone to occur, and the epidemiological investigation should be carried out timely to confirm the cluster. To prevent the transmission of COVID-19, the close contacts of the patients should be transferred to an assigned observation place on time for single room isolation. The awareness of COVID-19 prevention is low in some rural areas, reflected by many mass gathering activities and delayed medical care seeking after onset. It is necessary to strengthen the health education and take control measures in early period of epidemic.

Abstract
We report constraints on the dark photon effective kinetic mixing parameter (κ) with data taken from two p-type point-contact germanium detectors of the CDEX-10 experiment at the China Jinping Underground Laboratory. The 90% confidence level upper limits on κ of solar dark photon from 205.4 kg-day exposure are derived, probing new parameter space with masses (m_{V}) from 10 to 300 eV/c^{2} in direct detection experiments. Considering dark photon as the cosmological dark matter, limits at 90% confidence level with m_{V} from 0.1 to 4.0 keV/c^{2} are set from 449.6 kg-day data, with a minimum of κ=1.3×10^{-15} at m_{V}=200 eV/c^{2}.

Abstract
Cu3SbSe4-based materials have attracted much attention for thermoelectric power generation in the mid-temperature range due to their low cost, ecofriendliness, and abundant elements on the earth. However, the peak figure of merit (ZT) for the Cu3SbSe4-based system prepared by the fusion method is usually smaller than unity because of its high thermal conductivity. Here, we show that through a coprecipitation method combined with spark plasma sintering ultrafine-grained Cu3Sb0.94Sn0.06Se4-ySy (y = 0, 0.5) embedded with Cu3SbSe3 nanoprecipitates can be prepared. Due to the ultralow thermal conductivity and enhanced Seebeck coefficient, a record-high ZT value of 1.32 is achieved for the sample Cu3Sb0.94Sn0.06Se3.5Se0.5. The ultralow thermal conductivity is attributed to the enhanced phonon scattering caused by the nanoprecipitates and fine grains of the samples, and the improved Seebeck coefficient originates from the enhancement of electronic density-of-state effective mass. Present results demonstrate that excellent thermoelectric performance can be realized in dual-substituted and fine-grained Cu3Sb0.94Sn0.06Se4-ySy with nanoprecipitates.

Abstract
We present results on light weakly interacting massive particle (WIMP) searches with annual modulation (AM) analysis on data from a 1-kg mass p-type point-contact germanium detector of the CDEX-1B experiment at the China Jinping Underground Laboratory. Datasets with a total live time of 3.2 yr within a 4.2-yr span are analyzed with analysis threshold of 250 eVee. Limits on WIMP-nucleus (χ-N) spin-independent cross sections as function of WIMP mass (m_{χ}) at 90% confidence level (C.L.) are derived using the dark matter halo model. Within the context of the standard halo model, the 90% C.L. allowed regions implied by the DAMA/LIBRA and CoGeNT AM-based analysis are excluded at >99.99% and 98% C.L., respectively. These results correspond to the best sensitivity at m_{χ}<6 GeV/c^{2} among WIMP AM measurements to date.

Abstract
We report results on the searches of weakly interacting massive particles (WIMPs) with sub-GeV masses (m_{χ}) via WIMP-nucleus spin-independent scattering with Migdal effect incorporated. Analysis on time-integrated (TI) and annual modulation (AM) effects on CDEX-1B data are performed, with 737.1 kg day exposure and 160 eVee threshold for TI analysis, and 1107.5 kg day exposure and 250 eVee threshold for AM analysis. The sensitive windows in m_{χ} are expanded by an order of magnitude to lower DM masses with Migdal effect incorporated. New limits on σ_{χN}^{SI} at 90% confidence level are derived as 2×10^{-32}∼7×10^{-35} cm^{2} for TI analysis at m_{χ}∼50-180 MeV/c^{2}, and 3×10^{-32}∼9×10^{-38} cm^{2} for AM analysis at m_{χ}∼75 MeV/c^{2}-3.0 GeV/c^{2}.

Abstract
Objective: To evaluate the feasibility of cell-free tumor DNA in pleural effusion supernatant for assessing the tumor mutational burden (TMB) of advanced lung cancers. Methods: From December 2016 to August 2018, 34 lung cancer patients (19 males and 15 females) with pleural effusion were enrolled at Zhongshan Hospital, Fudan University. The median age of the patients was 65 (range, 34-85) years. Before systemic or local antitumor therapy, tumor specific mutations in tumor tissue, pleural effusion supernatant, pleural effusion sediment, and plasma samples from these patients were examined using targeted next-generation sequencing, and TMB levels were calculated respectively. Subgroup analysis was based on smoking history and driver mutation status. Statistical differences were determined using SPSS 16.0 software, and individual groups were compared using the one-way analysis of variance (ANOVA) and LSD-t test. Results: The median TMB level of pleural effusion supernatant was 6.23 mutations/Mb, similar to that of tumor tissue (6.23 vs 6.86 mutations/Mb, t=1.174, P=0.245), but significantly higher than that of pleural effusion sediment (2.49 mutations/Mb, t=3.044, P=0.003) and plasma (2.49 mutations/Mb, t=2.464, P=0.016). Compared with tumor tissue in TMB assessment, pleural effusion supernatant had a positive percentage agreement of 52% (9/17), and a negative percentage agreement of 65% (11/17). Subgroup analysis showed that the TMB level was higher in smokers (n=11) than that in non-smokers (n=23, 14.4 vs 5.4 mutations/Mb, t=3.238, P=0.003). Conclusion: For advanced lung cancer patients with pleural effusion, pleural effusion supernatant is a promising substitute to tumor tissue for TMB assessment, which is a potential biomarker for immunotherapy.

Abstract
Objective: To analyze the survival time of people living with HIV/AIDS and related influencing factors in Sichuan province during 1991-2017. Methods: A retrospective cohort study was conducted to analyze the data of 143 988 HIV/AIDS cases. The data were collected from Chinese HIV/AIDS Comprehensive Information Management System. Life table method was used to calculate the survival proportion of the cases, and Cox proportion hazard regression model was used to identify the factors related with survival time. Results: Among 143 988 HIV/AIDS cases a total of 30 420 cases died of AIDS related diseases (21.1%) and the average survival time was 11.51 years (95%CI: 11.39-11.64). Multivariate Cox regression analysis showed that the influencing factors for the survival of HIV/AIDS cases were gender (male vs. female, HR=1.35, 95%CI: 1.32-1.40), education level (primary school or below vs. junior middle school: HR=1.15, 95%CI: 1.12-1.18), ethnic group (Han vs. other ethnic groups, HR=1.46, 95%CI: 1.41-1.52), occupation (farmer vs. other occupations: HR=1.26, 95%CI: 1.22-1.29), age (≥55 years old vs. 15-24 years old: HR=3.18, 95%CI: 3.02- 3.36), disease phase (AIDS vs. HIV infection: HR=1.44, 95%CI: 1.39-1.48), antiretroviral therapy (ART) (receiving ART vs. receiving no ART: HR=0.20, 95%CI: 0.19-0.20), and CD(4)(+)T cell counts at diagnosis (>500 cells/μl vs.<200 cells/μl: HR=0.42, 95%CI: 0.40-0.45). Conclusions: The average survival time of HIV/AIDS cases was 11.51 years in Sichuan during 1991- 2017. The risk factors for the survival of the cases were male, education level of primary school or below, Han ethnic group, farmer, old age at diagnosis, disease phase, The protective factors for the survival of HIV/AIDS cases were receiving ART and higher CD(4)(+) T cell counts at diagnosis.
