Abstract
Objective: To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS). Methods: This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1∶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration. Results: (1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant (P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups (P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant (P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion: The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.

Abstract
Objective: This study sought to investigate the impact of different obesity patterns on coronary microvascular function in male patients with non-obstructive coronary artery disease. Methods: We retrospectively analyzed clinical data of male patients diagnosed with suspected coronary microvascular dysfunction (CMD) in the First Hospital of Shanxi Medical University between December 2015 and August 2021. All patients underwent the one-day rest and stress 13N-ammonia positron emission tomography myocardial perfusion imaging. Overall obesity was defined by body mass index (BMI) ≥28 kg/m2 and abdominal obesity was defined by waist circumference ≥90 cm. Hyperemic myocardial blood flow (MBF)<2.3 ml·min-1·g-1 or coronary flow reserve (CFR)<2.5 were referred as CMD. All patients were grouped based on their BMI and waist circumference. MBF, CFR, the incidence of CMD, hemodynamic parameters, and cardiac function were compared among the groups. Results: A total of 136 patients were included. According to BMI and waist circumference, patients were categorized into 3 groups: control group (n=45), simple abdominal obesity group (n=53) and compound obesity group (n=38). Resting MBF did not differ between groups (F=0.02,P=0.994). Compared with the control group, hyperemic MBF was significantly lower in the simple abdominal obesity and compound obesity groups ((2.82±0.64) ml·min-1·g-1, (2.44±0.85) ml·min-1·g-1 and (2.49±0.71) ml·min-1·g-1, both P<0.05, respectively). Hyperemic MBF was comparable among the groups of patients with obesity (P=0.772). CFR was significantly lower in the simle abdominal obesity group compared with the control group (2.87±0.99 vs. 3.32±0.62,P=0.012). Compared with the control group, CFR tended to be lower in the compound obesity group (3.02±0.91 vs. 3.32±0.62,P=0.117). The incidence of CMD was significantly higher in both the simple abdominal obesity and compound obesity groups than in the control group (62.3%, 52.6% vs. 22.2%, both P<0.01, respectively). Waist circumference was an independent risk factor for male CMD (OR=1.057, 95%CI: 1.013-1.103, P=0.011). Conclusions: In male patients with non-obstructive coronary artery disease, abdominal obesity is associated with decreased coronary microvascular function. Male patients with simple abdominal obesity face the highest risk of CMD.

Abstract
Botulinum toxin type A (BTX-A) can change the eye alignment system through chemodenervation on extraocular muscles. The breakdown in the balance of eye alignment system which is supported by agonistic and antagonistic muscles, in combination with brain feedback, can stimulates muscle remodeling to reconstruct new binocular vision and restore eye alignment. Since BTX-A was approved by FDA in 1989 for the treatment of strabismus, it has become one of the important non-surgical treatments for strabismus in children. It has the advantages of low invasiveness, short duration of anesthesia and scar-free after treatment. This review will introduce the history, injection methods, and types of BTX-A, as well as its application in the treatment of various types of strabismus in children.

Abstract
Abstract
Introduction/Objective
T-cell Lymphoma is overly aggressive. T cells overgrow triggered by aberrant T-cell signaling and transform into a lymphoma. Virus infection contributes to the transformation, for example, EBV (Epstein Barr Virus) virus is associated with Extranodal NK/T-cell lymphoma, Angioimmunoblastic T-cell lymphoma, and peripheral T-cell lymphoma, HHV-8 is associated with Primary Effusion Lymphoma, Kaposi sarcoma, and very rarely associated with T cell lymphoma. The HIV (Human Immunodeficiency Virus) virus is associated with Burkitt lymphoma, Plasmablastic lymphoma et al. Among these lymphomas, only Primary Effusion lymphoma is associated with all three virus infections and is a B cell lymphoma. T cell lymphoma with all three infections has not been reported. Since most patients are diagnosed with advanced disease. So early diagnosis of this disease is especially important.
Methods/Case Report
An HIV+ 38-year-old male with no significant medical history complained of weakness, dizziness, and presenting with lower extremities swelling, and anemia for the last 2 weeks. The patient had a history of an unsafe sexual encounter with male sex workers but denies iv. drug use and blood transfusion. The screen before endoscopy reveals active, acute Hepatitis B Virus infection. Endoscopy findings show gastritis. The biopsy specimen shows mucosa is diffusely infiltrated by atypical plasmablastic cells. Immunostaining reveals they are positive for CD3, CD7, CD30, MUM1, CD43, and HHV8, but negative for Cd2, Cd4, Cd5, Cd8, Cd10, Cd21, Cd23, Cd25, Cd34, Cd56, Cd138, CD19, CD20, CD79a, PAX5, CD45, CD57, P53, CyclinD1, BCL6, BCL2, ALK, c-MYC, TdT, Granzyme B, TIA, S-100, Pancytokeratin. In situ hybridization for EBER is positive, but negative for Kappa and Lambda. The proliferative index (Ki-67) is high (99%). The morphologic and immunophenotypic features are consistent with an EBV CD30+ high-grade lymphoma. The sequencing from OnkoSightTM Advanced Chronic Lymphoid NGS Report shows a BCL-6 and EP300 mutation that has not been reported in a publicly available database (COSMIC; gnomAD).
Results (if a Case Study enter NA)
N/A.
Conclusion
To our knowledge, this is the first reported case of EBV+/HHV-8+/HIV+ high grade T Cell Lymphoma in the stomach. This type of lymphoma is extremely aggressive, and the early diagnosis is particularly important for prognosis.

Abstract
Abstract
Introduction/Objective
The fibroepithelial stromal polyp is a benign polypoid proliferation of the stroma with overlying, usually squamous epithelium. It was originally reported in 1966 and is a generally recognized lesion of the female genital tract. Because the lesion contains atypical stromal cells, it can be mistaken for a sarcoma, particularly if it shows hypercellularity, pleomorphism, and atypical mitoses. It is often found in the female lower genital tract, urethra, and rarely extragenital sites, such as the breast. Other unusual locations such as the anus and nasal cavity have also been reported. The lesion is hormonally related and affects mostly reproductive-age women. Rare cases were reported in the male urinary tract and genital area. Because it is not well known in the bladder, overinterpretation as a sarcoma is possible.
Methods/Case Report
We report a ~60-year-old patient with a history of lower urinary tract symptoms due to prostatic hypertrophy on maximal medical therapy. He had been experiencing hematuria. On office cystoscopy, he was found to have a 3 cm prostate mildly obstructing the urethra, and 2 small velvety, erythematous patches on the posterior bladder wall. At cystoscopy, he was seen to have a small posterior bladder lesion, which was resected without difficulty. The pathology laboratory received two fragments of pink/tan soft tissue measuring 0.1 and 0.2 cm in the greatest dimension. On histology, the overlying urothelium was benign. The stroma was collagenous and hypocellular, containing scattered atypical and multinucleated cells, similar to the fibroepithelial stromal polyp well recognized in the female lower genital tract.
Results (if a Case Study enter NA)
N/A.
Conclusion
Benign fibroepithelial stromal polyp is an uncommon lesion usually seen in the lower genital tract of reproductive aged women. The presence in the bladder of a male is exceptionally rare. Recognition of the lesion will prevent overdiagnosis as a malignancy.

Abstract
We present a scheme for the full integration of terahertz (THz) frequency quantum cascade lasers (QCLs) within a dilution refrigerator in order to provide a directed delivery of THz power into the sample space. We describe a successful operation of a 2.68 THz QCL located on the pulse tube cooler stage of the refrigerator, with its output coupled onto a two-dimensional electron gas (2DEG) located on a milli-kelvin sample stage via hollow metal waveguides and Hysol thermal isolators, achieving a total loss from QCL to the sample of ∼-9 dB. The thermal isolators limit heat leaks to the sample space, with a base temperature of ∼210 mK being achieved. We observe cyclotron resonance (CR) induced in the 2DEG by the QCL and explore the heating impact of the QCL on all stages of the refrigerator. The CR effect induced by the THz QCL is observable at electron temperatures as low as ∼430 mK. The results show a viable route for the exploitation of THz QCLs within the environment of a dilution refrigerator and for the THz power delivery in very low-temperature (<0.5 K) condensed matter experiments.

Abstract
OBJECTIVES To advance the initiative of ending the global epidemic, long-lasting HIV protection is needed through sustained release of antiretroviral drugs for months to years. We investigated in macaques the safety and efficacy of biodegradable polycaprolactone implants releasing tenofovir alafenamide for HIV pre-exposure prophylaxis (PrEP). METHODS Implants were administered subcutaneously in the arm using a contraceptive trocar. Efficacy against vaginal simian-HIV (SHIV) infection was investigated in six pigtailed macaques that received two tenofovir alafenamide implants (0.35 mg/day), one in each arm, for a total release rate of tenofovir alafenamide at 0.7 mg/day. Macaques were exposed to SHIV twice weekly for 6 weeks. Statistical analyses were used to compare outcome with eight untreated controls. Histological assessments were performed on skin biopsies collected near implantation sites. RESULTS Median (range) tenofovir diphosphate level in PBMCs was 1519 (1068-1898) fmol/106 cells. All macaques with tenofovir alafenamide implants were protected against vaginal SHIV infection. In contrast, 7/8 controls were infected after a median of 4 SHIV exposures (P = 0.0047). Histological assessment of tissues near tenofovir alafenamide implant sites showed inflammation and necrosis in 5/6 animals, which were not evident by visual inspection. CONCLUSIONS We demonstrated complete protection against vaginal SHIV infection with two implants releasing a total of 0.7 mg of tenofovir alafenamide per day. We also identified tenofovir diphosphate concentrations in PBMCs associated with complete vaginal protection. Consistent with previous findings, we observed adverse local toxicity and necrosis near the tenofovir alafenamide implant site. Improved tenofovir alafenamide implants that are safe and maintain high efficacy have the potential to provide long-lasting protection against vaginal HIV infection.

Abstract
Background Exome sequencing (ES) is becoming more widely available in prenatal diagnosis. However, data on its clinical utility and integration into clinical management remain limited in practice. Herein, we report our experience implementing prenatal ES (pES) in a large cohort of fetuses with anomalies detected by ultrasonography using a hospital-based in-house multidisciplinary team (MDT) facilitated by a three-step genotype-driven followed by phenotype-driven analysis framework. Methods We performed pES in 1618 fetal cases with positive ultrasound findings but negative for karyotyping and chromosome microarray analysis between January 2014 and October 2021, including both retrospective (n=565) and prospective (n=1053) cohorts. The diagnostic efficiency and its correlation to organ systems involved, phenotypic spectrum, and the clinical impacts of pES results on pregnancy outcomes were analyzed. Results A genotype-driven followed by phenotype-driven three-step approach was carried out in all trio pES. Step 1, a genotype-driven analysis resulted in a diagnostic rate of 11.6% (187/1618). Step 2, a phenotype-driven comprehensive analysis yielded additional diagnostic findings for another 28 cases (1.7%; 28/1618). In the final step 3, data reanalyses based on new phenotypes and/or clinical requests found molecular diagnosis in 14 additional cases (0.9%; 14/1618). Altogether, 229 fetal cases (14.2%) received a molecular diagnosis, with a higher positive rate in the retrospective than the prospective cohort (17.3% vs. 12.4%, p<0.01). The diagnostic rates were highest in fetuses with skeletal anomalies (30.4%) and multiple organ involvements (25.9%), and lowest in fetuses with chest anomalies (0%). In addition, incidental and secondary findings with childhood-onset disorders were detected in 11 (0.7%) cases. Furthermore, we described the prenatal phenotypes for the first time for 27 gene-associated conditions (20.0%, 27/135) upon a systematic analysis of the diagnosed cases and expanded the phenotype spectrum for 26 (19.3%) genes where limited fetal phenotypic information was available. In the prospective cohort, the combined prenatal ultrasound and pES results had significantly impacted the clinical decisions (61.5%, 648/1053). Conclusions The genotype-driven approach could identify about 81.7% positive cases (11.6% of the total cohort) with the initial limited fetal phenotype information considered. The following two steps of phenotype-driven analysis and data reanalyses helped us find the causative variants in an additional 2.6% of the entire cohort (18.3% of all positive findings). Our extensive phenotype analysis on a large number of molecularly confirmed prenatal cases had greatly enriched our current knowledge on fetal phenotype-genotype correlation, which may guide more focused prenatal ultrasound in the future. This is by far the largest pES cohort study that combines a robust trio sequence data analysis, systematic phenotype-genotype correlation, and well-established MDT in a single prenatal clinical setting. This work underlines the value of pES as an essential component in prenatal diagnosis in guiding medical management and parental decision making.

Abstract
Post-tuberculosis lung disease (PTLD) refers to a group of lung diseases with chronic respiratory abnormalities, with or without clinical symptoms, partly or entirely caused by pulmonary tuberculosis. PTLD has high morbidity, disability rate and mortality, and has a serious impact on individuals, families and society. It is of great significance to fully understand its harm, explore its mechanism, and conduct in-depth research on its prevention, treatment, and rehabilitation.

Abstract
Objective: To understand the characteristics and depressive status of men who have sex with men (MSM) who self-reported HIV infection through heterosexual transmission and to provide evidence for personalized management of HIV infected people. Methods: A cross-sectional survey was carried out in Shandong province from September to December in 2019. Male HIV patients aged ≥15 years who self-reported HIV infection through heterosexual transmission were selected to verify the route of infection by one-to-one interview in Ji'nan, Qingdao, Weifang and Linyi cities of Shangdong province. According to the 1∶1 ratio, local HIV patients with age difference ≤3 years who self-reported MSM were selected as controls. A questionnaire survey was conducted, including data on demographic characteristics, behavior status, CES-D and PSSS. The related factors of the depressive symptoms and characteristics were analyzed. Results: A total of 373 male HIV patients were interviewed, and 39.7%(148/373) were confirmed as MSM after reexamination. The interviewers were: aged (40.3±12.0) years old, 41.9% (62/148) married/cohabiting. 27.0% (40/148) had been tested before HIV diagnosis, 71.6% (106/148) had homosexual partners ≥2 and 55.4% (82/148) had depressive symptom. Multivariate analysis showed that the MSM without HIV testings before diagnosis, had homosexual partners ≥2 before diagnosis, had first homosexual behavior at the age >30 years old and with depressive symptoms were more likely to conceal the true infection route. The incidence of depression among MSM who self-reported HIV infection through heterosexual transmission was related to physical health status social support and occupational stability. Conclusions: Some male HIV persons self-reported as being heterosexually transmitted were really transmitted through homosexual behavior. There were high-risk behaviors such as multiple partners and intersex among this group, and with high incidence of depression. It is necessary to encourage the reexamination program during follow-up and target on psychological and behavioral interventions, continuously.

Abstract
Soil water repellency (SWR) is a physical phenomenon whereby water cannot penetrate or has difficulty penetrating the soil surface. There are many factors involved in its occurrence, but the main factors controlling its emergence in loess remain unclear. In this work, we have studied numerous physicochemical and biological factors functioning in different dominant vegetations (Pinus tabulaeformis Carr., Robinia pseudoacacia L., and Hippophae rhamnoides L.) in a loess hilly region by gas chromatography-mass spectrometry (GC-MS) and high-throughput sequencing techniques. We observed that more than 75% of the soils under Robinia and Hippophae are categorized as slightly or strongly water repellent, while nearly 50% of the soils under Pinus are categorized as severely to extremely water repellent. The relative concentrations of total free lipids in the soil in the same water-repellency class were Pinus > Robinia > Hippophae, where fatty acids, alkanols, and sterols were positively correlated with SWR, whereas alkanes were not. For the abundance and diversity index of bacterial and fungal communities, the three species ranked in the following order: Robinia ≈ Hippophae > Pinus. Thus, solvent-extractable polar waxes were indicated to be better preserved in water-repellent soils under Pinus due to lower microbial diversity than Robinia and Hippophae. Here, we demonstrate polar waxes to be the principal factor controlling SWR. Moreover, the dominant phyla of fungi varied greatly than those of bacteria under three vegetation types. Correlation analysis showed that the abundance of Actinobacteria in dominant bacteria increased with SWR. Nonmetric multidimensional scaling suggested the fungal community in different water-repellent soils under Pinus to vary more than those under Robinia and Hippophae. The indicator species mainly belonged to Actinobacteria in bacteria and Basidiomycota in fungi at the phylum level; this finding was further supported by the linear discriminant analysis (LDA) effect size (LEfSe). Additionally, GC-MS identified a small amount of ergosterol, a specific biomarker of fungi under Pinus. These pieces of evidence collectively reveal that severe to extreme SWR occurs under Pinus and appears to be the most influenced by fungi and actinomycetes when the topsoil is close to air drying. However, there is a need for further testing on different plant species or land use.

Abstract
Abstract
Background
The exercise has well-documented health benefits on cardiovascular disease, and the use of mobile health (mHealth) may promote physical activity to reduce the risk.
Objective
The present study aimed to investigate the compliance of exercise dose and pattern through wearables and mHealth in subjects with cardiac arrhythmia in a real-world setting.
Method
The photoplethysmography (PPG)-algorithms with wearables to detect the ectopic and AF have been developed in the HUAWE HEART STUDY. Using the PPG-based smart devices, the adult subjects with identified arrhythmia received the personalized App-based lifestyle and exercise package was proposed. The V̇O2 peak (mL kg–1 min–1)was estimated from a non-exercise prediction model. The metabolic equivalent (MET)/week and Borg scale were utilized for the assessment of intensity of exercise. All subjects followed up for 3 months for the compliance to the exercise package.
Results
There were 7419 subjects (mean age ± standard deviation, SD, 35±12 years old, 92.1% male) who identified with the arrhythmia between April 1, 2021 and Dec 31, 2021. Among them, there were 165 subjects with identified AF, and 5277 subjects with the ectopic. The obstructive sleep apnea was the most reported risk profile (2643, 35.6%), while 1326 (17.9%) subjects were overweight.
Upon the baseline assessment, the personalized exercise package for cardiovascular disease prevention were proposed for 2864 subjects, exercise package to control the weight for 2510 subjects, and exercise package to reduce the weight for 1886 subjects.
Among 6366 subjects who took the exercise packages, 1867 (29.3%) subjects achieved target exercise, 395 (6.2%) subjects over target exercise, and 4104 (64.5%) under target exercise. The V̇O2 peak (mL kg–1 min–1, SD)in subjects who achieved the target exercise package, under target exercise, and over target exercise were (47.36±5.12, 32.14±22.47, and 65.99±10.38, p<0.001).
For subjects who achieved target exercise, the intensity of exercise was as follows: 0.4% with low-intensity exercise, 95.8% with moderate-intensity exercise, and 3.7% with high-intensity exercise. Nonetheless, there were 37.7% of low-intensity, 60.6% of moderate-intensity exercise, and 1.7% with high-intensity exercise in subjects who didn't achieve exercise target.
77.9% subjects under target exercise had less than 1/week of physical activity, while there was only 12.9% in subjects with target exercise (p<0.001).
Compared to randomly selected 8000 subjects (mean age ± SD, 39±13 years, 80.8% male) without exercise package, the proportion of steps/day over 10000 of 20% was significantly increased in subjects (37±13 years, 91.3% male) receiving the personalized App-based exercise package (31.2%, vs. 12.2%, p<0.001).
Conclusion
The wearables facilitated the improvement of physical activity habit in subjects with cardiac arrhythmia, but subjects-centered self-management would be enhanced to the target exercise.

Abstract
Abstract
Background
The effects of sodium-glucose cotransporter 2 inhibitors (SGLT2I) versus dipeptidyl peptidase-4 inhibitors (DPP4I) on the risk of new gout diagnosis have not been explored. This study aims to compare the effects of SGLT2I against DPP4I on gout risks in a Chinese population.
Methods
This was a retrospective population-based cohort study of patients with type-2 diabetes mellitus treated with SGLT2I or DPP4I between January 1st, 2015 and December 31st, 2020 in Hong Kong. The study outcomes are new-onset gout and all-cause mortality. Propensity score matching (1:1 ratio) between SGLT2I and DPP4I was performed. Univariable and multivariable Cox regression analysis models were conducted. Competing risks models and multiple approaches based on the propensity score were applied.
Patients
This study included 60996 patients (median age: 62.3 years old, 54.96% males; SGLTI group: n=21690; DPP4I group: n=39306).
Results
In the matched cohort, 1096 developed gout (IR: 2.52%) and 2195 died (IR: 5.05%). Univariable Cox regression showed that SGLT2I use was associated with lower risks of new diagnosis of gout (hazard ratio [HR]: 0.34; 95% confidence interval [CI]: 0.30–0.39; P-value<0.0001) and all-cause mortality (HR: 0.35; 95% CI: 0.32–0.39; P-value<0.0001) compared to DPP4I. The associated remained for both new diagnosis of gout (HR: 0.46; 95% CI: 0.37–0.57; P-value<0.0001) and all-cause mortality (HR: 0.38; 95% CI: 0.33–0.44; P-value<0.0001) after adjusting for significant demographics, past comorbidities, and non-SGLT2I/DPP4I medications. The risks of gout were lowered in each types of SGLT2I. The results were consistent on competing risk and other propensity score approaches analyses.
Conclusions
SGLT2I use was associated with lower risks of new gout diagnosis compared to DPP4I use.

Abstract
OBJECTIVES To summarize our experience in the application of radiofrequency ablation (RFA) and microwave ablation (MWA) for selective fetal reduction in complicated monochorionic pregnancies and compare the perinatal outcome of the two techniques. METHODS This was a retrospective study of data from a consecutive cohort of all monochorionic twin pregnancies that underwent selective fetal reduction with RFA or MWA at Peking University Third Hospital, Beijing, China from January 2012 to December 2018. All surviving cotwins were followed up to assess their neurodevelopment using the Age & Stage Questionnaire, Chinese version. Perinatal and neurodevelopmental outcomes were compared between the RFA and MWA groups. We also fitted multivariable models to test the association between procedure-related factors and the main perinatal outcomes, including preterm birth (PTB) < 37 weeks' gestation, intrauterine fetal death (IUFD) of the cotwin, adverse outcome (defined as occurrence of IUFD of the cotwin, termination of pregnancy or PTB < 28 weeks) and overall survival. RESULTS In total, 45 cases (42 twin and three triplet pregnancies) underwent RFA and 126 cases (105 twin and 21 triplet pregnancies) underwent MWA. The overall survival rates in monochorionic diamniotic twin pregnancies were similar between the RFA and MWA groups (61.0% vs 67.0%; P = 0.494). However, pregnancies whose indication for fetal reduction was selective intrauterine growth restriction or twin reversed arterial perfusion had higher overall survival rates (75.5% and 82.6%, respectively) compared with those in other indication groups. A total of 104 children were followed up (20 in the RFA group and 84 in the MWA group); four (20.0%) and eight (9.5%) children were assessed as having overall developmental delay in the RFA and MWA groups, respectively, with no significant difference between the two groups. Multivariable analyses showed that procedure indication, number of ablation cycles and gestational age at procedure were associated significantly with the main perinatal outcomes. CONCLUSIONS RFA and MWA for selective fetal reduction in complicated monochorionic pregnancies can achieve similar overall survival rate and neurodevelopmental outcome, but MWA is associated with a lower risk of preterm birth. Moreover, procedure-related factors are associated significantly with perinatal outcome. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
BACKGROUND Despite growing concern regarding the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) delta variant of concern (VOC), the respiratory and physical functions of patients with delta VOC post-discharge have not been investigated compared to those of patients with ancestral SARS-CoV-2.METHODS Sixty-three discharged patients with coronavirus disease (COVID-19) were included. Patients were divided into delta VOC and ancestral SARS-CoV-2 groups. On Day 14 post-discharge, differences in chest computed tomography, modified Medical Research Council and Borg Dyspnoea Scale scores, and Manual Muscle Test scores were compared. Prognoses of respiratory and physical function were compared between patients who recovered from moderate and severe COVID-19.RESULTS Of the 63 patients, respectively 28 and 35 were in the delta VOC and ancestral SARS-CoV-2 groups. On Day 14 post-discharge, 35 patients (56.5%) had abnormalities on imaging. Visual semi-quantitative scores of both lungs were significantly higher in the severe group. However, there was no difference in this or any other score ratings between the groups.CONCLUSION At 14 days post-discharge, ground glass opacities and pleural thickening were the most common residual findings; no difference in respiratory and physical functions during the convalescence period were noted in patients with SARS-CoV-2 delta VOC and ancestral SARS-CoV-2.

Abstract
Objective: To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE)-hepatic arterial infusion chemotherapy (HAIC)-targeted-immune quadruple therapy in patients with intermediate and advanced-stage hepatocellular carcinoma (HCC). Methods: 101 patients with intermediate and advanced stage HCC were enrolled according to the inclusion and exclusion criteria, and then they were divided into a combination group and a control group. Patients in the combination group was treated with TACE-HAIC-targeted-immune quadruple therapy, while the control group was only treated with TACE therapy. The overall survival (OS), progression-free survival (PFS), and treatment-related adverse reactions were statistically analyzed in the two groups of patients. Statistical analysis was carried out by t-test, χ2 test, rank sum test, Kaplan-Meier curve, log-rank test, Cox regression (or proportional hazards model) analysis according to different data. Results: The tumor objective response rate and disease control rate as evaluated by mRECIST 1.1 criteria in the combination group were 80% and 94%, respectively, which were significantly higher than those in the control group, 41.2% (P<0.001) and 74.5% (P=0.007). The OS and PFS of the combination group were 15.6 months [95%CI 11.3-NA ] and 8.8 months [95%CI 6.9-12.0], respectively, which were significantly better than the control group at 6.1 months [95%CI 5.3-6.6] (P<0.001) and 3.2 months [95%CI 3.0-3.6] (P<0.001). Gastric ulcer incidence was significantly higher in the combination group (9/50, 18%) than that in the control group (2/51, 3.9%) (P=0.023). Conclusion TACE-HAIC-targeted-immune quadruple therapy is a more effective treatment mode for intermediate and advanced-stage HCC than TACE alone, and attention should be paid to the monitoring of target immune-related adverse reactions.

Abstract
Objective: To investigate the effects of low-dose photodynamic therapy on the proliferation, regulation, and secretion functions of human adipose mesenchymal stem cells (ADSCs) and the related mechanism, so as to explore a new method for the repair of chronic wounds. Methods: The experimental research methods were adopted. From February to April 2021, 10 patients (5 males and 5 females, aged 23 to 47 years) who underwent cutaneous surgery in the Department of Dermatology of the First Affiliated Hospital of Army Medical University (the Third Military Medical University) donated postoperative waste adipose tissue. The cells were extracted from the adipose tissue and the phenotype was identified. Three batches of ADSCs were taken, with each batch of cells being divided into normal control group with conventional culture only, photosensitizer alone group with conventional culture after being treated with Hemoporfin, irradiation alone group with conventional culture after being treated with red light irradiation, and photosensitizer+irradiation group with conventional culture after being treated with Hemoporfin and red light irradiation, with sample number of 3 in each group. At culture hour of 24 after the treatment of the first and second batches of cells, the ADSC proliferation level was evaluated by 5-ethynyl-2'-deoxyuridine staining method and the migration percentage of HaCaT cells cocultured with ADSCs was detected by Transwell experiment, respectively. On culture day of 7 after the treatment of the third batch of cells, the extracellular matrix protein expression of ADSCs was detected by immunofluorescence method. The ADSCs were divided into 0 min post-photodynamic therapy group, 15 min post-photodynamic therapy group, 30 min post-photodynamic therapy group, and 60 min post-photodynamic therapy group, with 3 wells in each group. Western blotting was used to detect the protein expressions and calculate the phosphorylated mammalian target of rapamycin complex (p-mTOR)/mammalian target of rapamycin (mTOR), phosphorylated p70 ribosomal protein S6 kinase (p-p70 S6K)/p70 ribosomal protein S6 kinase (p70 S6K) ratio at the corresponding time points after photodynamic therapy. Two batches of ADSCs were taken, and each batch was divided into normal control group, photodynamic therapy alone group, and photodynamic therapy+rapamycin group, with 3 wells in each group. At culture minute of 15 after the treatment, p-mTOR/mTOR and p-p70 S6K/p70 S6K ratios of cells from the first batch were calculated and detected as before. On culture day of 7 after the treatment, extracellular matrix protein expression of cells from the second batch was detected as before. Data were statistically analyzed with one-way analysis of variance and least significant difference test. Results: After 12 d of culture, the cells were verified as ADSCs. At culture hour of 24 after the treatment, the ADSC proliferation level ((4.0±1.0)% and (4.1±0.4)%, respectively) and HaCaT cell migration percentages (1.17±0.14 and 1.13±0.12, respectively) in photosensitizer alone group and irradiation alone group were similar to those of normal control group ((3.7±0.6)% and 1.00±0.16, respectively, P>0.05), and were significantly lower than those of photosensitizer+irradiation group ((34.2±7.0)% and 2.55±0.13, respectively, P<0.01). On culture day of 7 after the treatment, compared with those in normal control group, the expression of collagen Ⅲ in ADSCs of photosensitizer alone group was significantly increased (P<0.05), and the expressions of collagen Ⅰ and collagen Ⅲ in ADSCs of irradiation alone group were significantly increased (P<0.01). Compared with those in photosensitizer alone group and irradiation alone group, the expressions of collagen Ⅰ, collagen Ⅲ, and fibronectin of ADSCs in photosensitizer+irradiation group were significantly increased (P<0.01). Compared with those in 0 min post-photodynamic therapy group, the ratios of p-mTOR/mTOR and p-p70 S6K/p70 S6K of ADSCs in 15 min post-photodynamic therapy group were significantly increased (P<0.01), the ratios of p-p70 S6K/p70 S6K of ADSCs in 30 min post-photodynamic therapy group and 60 min post-photodynamic therapy group were both significantly increased (P<0.01). At culture minute of 15 after the treatment, compared with those in normal control group, the ratios of p-mTOR/mTOR and p-p70 S6K/p70 S6K of ADSCs in photodynamic therapy alone group were significantly increased (P<0.05 or P<0.01). Compared with those in photodynamic therapy alone group, the ratios of p-mTOR/mTOR and p-p70 S6K/p70 S6K of ADSCs in photodynamic therapy+rapamycin group were significantly decreased (P<0.05). On culture day of 7 after the treatment, compared with those in normal control group, the expressions of collagen Ⅰ, collagen Ⅲ, and fibronectin of ADSCs in photodynamic therapy alone group were significantly increased (P<0.01). Compared with those in photodynamic therapy alone group, the expressions of collagen Ⅰ, collagen Ⅲ, and fibronectin of ADSCs in photodynamic therapy+rapamycin group were significantly decreased (P<0.01). Conclusions: Low-dose photodynamic therapy can promote the proliferation of ADSCs, improve the ability of ADSCs to regulate the migration of HaCaT cells, and enhance the secretion of extracellular matrix protein by rapidly activating mTOR signaling pathway.

Abstract
Burns not only affect children's physiology and psychology, but also bring a burden to their families and society, which can be prevented to a large extent. By introducing the epidemiological characteristics and current disease burden of pediatric burns, and combining them with the Haddon matrix, this paper reviews the progresses on the influencing factors and interventional measures of pediatric burns from three aspects: host, injury factors, and environment. It aims to provide a theoretical basis for the developments of burn risk assessment tools suitable for Chinese pediatric burns and to provide a reference for the formulation of related comprehensive and multi-level intervention measures.

Abstract
Objective: To investigate the clinicopathological, molecular genetic, immunohistochemical and prognostic features of spinal solitary fibrous tumor (SFT). Methods: The clinical data of 12 cases of spinal SFT in Beijing Tsinghua Changgung Hospital, Affiliated to Tsinghua University, diagnosed from January 2015 to December 2021 were collected and reclassified. The clinical data, histopathology, immunohistochemistry and molecular genetics were analyzed. Follow-up and related literature reviews were conducted. Results: Among the 12 patients, there were 5 males and 7 females; the age ranged from 31 to 73 years, with a median age of 50.5 years. All 12 cases were primary tumors, including 4 cases diagnosed at the first time and 8 recurrent cases. Among the 12 cases, 8 were WHO grade 1, 3 were WHO grade 2, and 1 was WHO grade 3. Microscopically, the spinal SFT appeared as a spindle cell tumor, the stroma was rich in many thin-walled blood vessels with various histological features such as cell morphology and necrosis according to the different tumor grade. All (12/12) of the cases expressed vimentin and STAT6 (diffuse and strong nuclear stain), 11 cases (11/12) expressed both CD34 and bcl-2, and 7 cases (7/12) expressed CD99. Next-generation sequencing showed that 12 (12/12) of the patients had NAB2-STAT6 gene fusion. The 12 patients were followed up for 6 to 80 months. There were no recurrences or metastases in the 4 first cases after operation. Among the 8 recurrent cases, 2 of the patients relapsed and 2 died. Conclusions: Spinal SFT is rare and has a high recurrence tendency. Many aspects need to be considered in the diagnosis process. STAT6 is a relatively specific marker for the diagnosis of this tumor. Complete surgical resection is the preferred treatment while postoperative radiotherapy is recommended to reduce tumor recurrence.

Abstract
Objective: To determine the characteristics and progress of the visual acuity and refractive state of schoolchildren in Huangzhong District, Xining City, Qinghai Province in China. Methods: Cohort study. Department of Ophthalmology, Beijing Children's Hospital carried out a cohort study by collecting the visual acuity and refractive state of Grade 1-5 schoolchildren among 16 primary schools in Huangzhong District, Xining City, Qinghai Province in September 2020 and July 2021. Cycloplegic retinoscopy with eye drop which contained tropicamide (0.5%) and phenylephrine hydrochloride (0.5%) was performed in children with low vision(<1.0). Myopia was defined as the spherical equivalent (SE) ≤-0.5 D after cycloplegic retinoscopy. Measurement data was analyzed by t-test and enumeration data was analyzed by χ2 test. Multiple linear regression was used to analyze the influencing factors. Results: The 2 489 individuals with repeated tests in two years were included in the follow-up study, among whom the prevalence of myopia was 26.24%(653/2 489) in 2020, while 32.94% (820/2 489)respectively in 2021. The incidence of myopia in one school year from grades 1 to 5 was 11.19%(47/420), 5.44%(21/386), 6.39%(25/391), 11.52%(44/382) and 11.67%(30/257). The average SE of children in all grades in 2021 increased negatively from the previous year (Grade 1 to Grade 5 increased respectively: 0.40 D, 0.69 D, 0.62 D, 0.52 D and 0.37 D). Conclusions: The prevalence of myopia among schoolchildren in Huangzhong District, Xining City, Qinghai Province was relatively high. There were two peaks of myopia incidence in the first, fourth and fifth grades. Female, age, and the baseline of SE were the related influencing factors for myopia progression.

Abstract
Objective: To analyze the overweight and obesity status of students in the national pilot counties of the Nutrition Improvement Program for Rural Compulsory Education Students in 2019 and its associated factors. Methods: In 2019, a multi-stage cluster random sampling method was used to select about 40 students from each grade in primary and secondary schools in China's central and western regions where the Nutrition Improvement Program for Rural Compulsory Education Students was implemented. The height and weight of the children were measured using height or weight scales. The school questionnaire and county questionnaire were used to investigate the associated factors. A Chi-square test was used for comparison between groups. The logistic regression analysis was used to analyze the associated factors. Results: In 2019, the prevalence of overweight and obesity among rural primary and secondary school students aged 6-15 years in central and western China 2019 was 11.5%. It was higher for boys (13.1%) than that for girls (9.8%), higher in central (14.3%) than that in the west (9.9%) and higher for elementary school students (12.4%) than that for secondary school students (9.5%, all P<0.001). The logistic regression showed that boys (OR=1.388), primary school students (OR=1.271), students without other dietary subsidies(OR=1.037), schools in rural areas (OR=1.133), schools with enterprise-based feeding mode (OR=1.043), schools without the provision of lunch (OR=1.143), schools without the provision of dinner (OR=1.122), and schools without providing drinking water (OR=1.015) were positively associated with overweight and obesity among students (P<0.05). Schools with snack shops (OR=0.952) were negatively associated with overweight and obesity among students (P<0.001). Conclusion: A certain proportion of primary and secondary school students in rural areas of central and western China are overweight and obese. The prevalence is not only related to children's gender, school section and county area but also related to school meals, whether schools provide drinking water and other factors.

Abstract
Species distribution model, a mathematical model theoretically based on the temporal and spatial locations of species in the ecosystem and their associations with other species, is useful to display the current species distribution and predict the future species distribution, which has been widely applied in ecology, biogeography and spatial transmission of infectious diseases. Integrated species distribution model is a comprehensive, summative and reliable combination model that simultaneously uses multiple species distribution models or integrates multiple data sources for modeling. This review describes the theory and classification of species distribution models, and summarizes the creation and verification of integrated species distribution models and their applications in parasitic disease prevention and control. During the practical applications of integrated species distribution models, the study scale, niche matching, big data utilization, combination of multidisciplinary methods and knowledge background and ecological implications should be emphasized.
