ABSTRACT

Objective: To investigate the effect of acetyl-CoA carboxylase 1 (ACC1) knockdown on the migration of esophageal squamous cell carcinoma (ESCC) KYSE-450 cell and underlying mechanism. Methods: Lentiviral transfection was conducted to establish sh-NC control cell and ACC1 knocking down cell (sh-ACC1). Human siRNA HSP27 and control were transfected by Lipo2000 to get si-HSP27 and si-NC. The selective acetyltransferase P300/CBP inhibitor C646 was used to inhibit histone acetylation and DMSO was used as vehicle control. Transwell assay was performed to detect cell migration. The expression of HSP27 mRNA was examined by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) and the expressions of ACC1, H3K9ac, HSP27 and epithelial-mesenchymal transition-related proteins E-cadherin and Vimentin were detected by western blot. Results: The expression level of ACC1 in sh-NC group was higher than that in sh-ACC1 group (P<0.01). The number of cell migration in sh-NC group was (159.00±24.38), lower than (361.80±26.81) in sh-ACC1 group (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-NC group were statistically significant compared with sh-AAC1 group (P<0.05). The migrated cell number in sh-NC+ si-NC group was (189.20±16.02), lower than (371.60±38.40) in sh-ACC1+ si-NC group (P<0.01). The migrated cell number in sh-NC+ si-NC group was higher than that in sh-NC+ si-HSP27 group (152.40±24.30, P<0.01), and the migrated cell number in sh-ACC1+ si-NC group was higher than that in sh-ACC1+ si-HSP27 group (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-NC+ si-NC group were significantly different from those in sh-ACC1+ si-NC and sh-NC+ si-HSP27 groups (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-ACC1+ si-NC group were significantly different from those in sh-ACC1+ si-HSP27 group (P<0.01). After 24 h treatment with C646 at 20 μmmo/L, the migrated cell number in sh-NC+ DMSO group was (190.80±11.95), lower than (395.80±17.10) in sh-ACC1+ DMSO group (P<0.01). The migrated cell number in sh-NC+ DMSO group was lower than that in sh-NC+ C646 group (256.20±23.32, P<0.01). The migrated cell number in sh-ACC1+ DMSO group was higher than that in sh-ACC1+ C646 group (87.80±11.23, P<0.01). The protein expressions of H3K9ac, HSP27, E-cadherin and Vimentin in sh-NC+ DMSO group were significantly different from those in sh-ACC1+ DMSO group and sh-NC+ C646 group (P<0.01). The protein expression levels of H3K9ac, HSP27, E-cadherin and Vimentin in sh-ACC1+ DMSO group were significantly different from those in sh-ACC1+ C646 group (P<0.01). Conclusion: Knockdown of ACC1 promotes the migration of KYSE-450 cell by up-regulating HSP27 and increasing histone acetylation.

ABSTRACT

Objective:To investigate the clinical diagnosis and prognosis in patients with emergency septic encephalopathy.Methods:Case data of 131 patients with septic encephalopathy admitted to the emergency department of Chuiyangliu Hospital Affiliated to Tsinghua University from January 2020 to December 2021 were selected and divided into survival group and death group. Logistic regression was used to analyze the risk factors affecting diagnosis, treatment and prognosis in patients with septic encephalopathy. Receiver operating characteristic (ROC) curve was used to evaluate the prognostic value of each indicator in patients with septic encephalopathy.Results:The mean arterial pressure (MAP) and pH level in the death group were lower than those in the survival group, while the C reactive protein (CRP), troponin T (TNI), D-dimer, lactic acid, creatinine, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, Sequential Organ Failure Assessment (SOFA), proportion of ventilator support, proportion of vasoactive drug use in the death group were higher than those in the survival group, with statistically significant difference (all P<0.05). Multivariate logistic regression analysis showed that APACHEⅡ score ( OR=1.290, 95% CI: 1.121-1.485, P<0.001), SOFA score ( OR=1.447, 95% CI: 1.183-1.796, P<0.001), the proportion of vasoactive drug use ( OR=18.720, 95% CI: 4.486-78.108, P<0.001) could predict the prognosis of patients with septic encephalopathy, and the area under the curve (AUC) was 0.823, 0886, 0.787. Conclusions:Elderly age and underlying brain diseases are important factors in the occurrence of septic encephalopathy. APACHE Ⅱ score, SOFA score, and the proportion of vasoactive drug use can predict the prognosis of patients with septic encephalopathy.

ABSTRACT

Objective:To investigate the diagnostic value of soluble interleukin 7 receptors (sIL-7R) in combination with other biomarkers for emergency sepsis.Methods:A prospective study method was used to select 102 emergency patients from the Chuiyangliu Hospital affiliated to Tsinghua University and Baoding First Central Hospital from December 2020 to June 2022. They were divided into sepsis group (80 cases) and non-sepsis group (22 cases), and 20 healthy people in the same period were selected as the control group. The patient data were collected, the relevant biomarker examination was improved and the values were recorded. Using statistical methods, the significance of sIL-7R for the diagnosis of sepsis was assessed, and important indicators related to the presence of sepsis were also screened to construct a model for the early diagnosis of sepsis.Results:The levels of interleukin-6 (IL-6), C-reactive protein (CRP), age and sIL-7R in sepsis group were significantly higher than those in non-sepsis group and control group (all P<0.01). Further, the sIL-7R, age, CRP, and IL-6 were selected as important diagnostic indicators of sepsis by comparing the sepsis and non-sepsis groups using R-language statistical software. Receiver operating characteristic (ROC) curve was plotted, and the area under the curve (AUC) for diagnosing sepsis of the four indexes were calculated as 0.759, 0.622, 0.716 and 0.640, respectively. The diagnostic model based on the four indexes performed better than other indexes, and the AUC value reached 0.869. The AUC of sIL-7R in the diagnosis of sepsis was higher than that of the other three indexes, and the detection of SIL-7R in combination with other inflammatory indexes was significantly higher than that of the four indexes, which had obvious advantages for the early diagnosis of sepsis. Conclusions:sIL-7R is a good biological marker for the early diagnosis of sepsis, and its combination with age, CRP, and IL-6 can better improve the early diagnosis of sepsis.

ABSTRACT

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

ABSTRACT

Objective: To examine the feasibility and surgical approach of removing type D trigeminal schwannoma through nasal cavity and nasal sinus under endoscope. Methods: Eleven patients with trigeminal schwannoma who were treated in the Department of Otorhinolaryngology, Qilu Hospital of Shandong University from December 2014 to August 2021 were analyzed retrospectively in this study. There were 7 males and 4 females, aged (47.5±13.5) years (range: 12 to 64 years). The neoplasm involved the pterygopalatine fossa, infratemporal fossa, ethmoidal sinus, sphenoid sinus, cavernous sinus, and middle cranial fossa. The size of tumors were between 1.6 cm×2.0 cm×2.0 cm and 5.7 cm×6.0 cm×6.0 cm. Under general anesthesia, the tumors were resected through the transpterygoid approach in 4 cases, through the prelacrimal recess approach in 4 cases, through the extended prelacrimal recess approach in 2 cases, and through the endoscopic medial maxillectomy approach in 1 case. The nasal endoscopy and imaging examination were conducted to detect whether neoplasm recurred or not, and the main clinical symptoms during follow-up. Results: All the surgical procedures were performed under endonasal endoscope, including Gross total resection in 10 patients. The tumor of a 12-year-old patient was not resected completely due to huge tumor size and limited operation space. One patient was accompanied by two other schwannomas located in the occipital region and the ipsilateral parotid gland region originating from the zygomatic branch of the facial nerve, both of which were removed concurrently. After tumor resection, the dura mater of middle cranial fossa was directly exposed in the nasal sinus in 2 cases, including 1 case accompanied by cerebrospinal fluid leakage which was reconstructed by a free mucosal flap obtained from the middle turbinate, the other case was packed by the autologous fat to protect the dura mater. The operation time was (M(IQR)) 180 (160) minutes (range: 120 to 485 minutes). No complications and deaths were observed. No recurrence was observed in the 10 patients with total tumor resection during a 58 (68) months' (range: 10 to 90 months) follow-up. No obvious change was observed in the facial appearance of all patients during the follow-up. Conclusion: Type D trigeminal schwannoma involving pterygopalatine fossa and infratemporal fossa can be removed safely through purely endoscopic endonasal approach by selecting the appropriate approach according to the size and involvement of the tumor.

ABSTRACT

This study employed the α-glucosidase inhibitory activity model as an anti-diabetic assay and implemented a bioactivity-guided isolation strategy to identify novel natural compounds with potential therapeutic properties. Hypericum sampsoniiwas investigated, leading to the isolation of two highly modified seco-polycyclic polyprenylated acylphloroglucinols (PPAPs) (1 and 2), eight phenolic derivatives (3-10), and four terpene derivatives (11-14). The structures of compounds 1 and 2, featuring an unprecedented octahydro-2H-chromen-2-one ring system, were fully characterized using extensive spectroscopic data and quantum chemistry calculations. Six compounds (1, 5-7, 9, and 14) exhibited potential inhibitory effects against α-glucosidase, with IC50 values ranging from 0.050 ± 0.0016 to 366.70 ± 11.08 μg·mL-1. Notably, compound 5 (0.050 ± 0.0016 μg·mL-1) was identified as the most potential α-glucosidase inhibitor, with an inhibitory effect about 6900 times stronger than the positive control, acarbose (IC50 = 346.63 ± 15.65 μg·mL-1). A docking study was conducted to predict molecular interactions between two compounds (1 and 5) and α-glucosidase, and the hypothetical biosynthetic pathways of the two unprecedented seco-PPAPs were proposed.

ABSTRACT

OBJECTIVE@#This study aims to clarify how the stimulation of acupuncture points is achieved by needles with different surface texture during acupuncture; it also seeks to lessen injury at the insertion site and increase the therapeutic efficacy of acupuncture, by simulating the mechanical effects of various needle surface patterns on Zusanli (ST36) without changing the radius of acupuncture needles.@*METHODS@#Five acupuncture needle models with different surface patterns, including the smooth needle, the lined needle, the ringed needle, the left-hand threaded needle and the right-hand threaded needle, and a layered model of the Zusanli acupoint were used to investigate how to reduce tissue damage and increase stimulation during acupuncture treatment. Puncturing of the skin as well as lifting-inserting and twisting needle manipulations were simulated using these models, and the degree of damage and force of stimulation caused by the acupuncture needles with different surface patterns during acupuncture were compared.@*RESULTS@#The smooth needle and the lined needle caused the least tissue damage during insertion, while the left-hand threaded and the right-hand threaded needles caused the most damage. The ringed needle, the left-hand threaded needle and the right-hand threaded needle stimulated the acupoint tissue more during lifting-inserting manipulations, while the lined needle and the smooth needle produced less stimulation. The stimulation of the lined needle on the acupoint tissue was the largest during twisting manipulation, whereas the left-hand threaded needle and the right-hand threaded needle had smaller effects. In lifting-inserting and twisting manipulations, both the left-hand threaded needle and right-hand threaded needle provided more stimulation, but the torsion direction in which they produced better stimulation was the opposite.@*CONCLUSION@#According to the simulation results, the ringed pattern enhances stimulation best in the lifting-inserting manipulation, whereas the lined pattern enhances stimulation best in the twisting manipulation. Both the right-hand and left-hand thread patterns have certain enhancing effects in these two operations. Taking the geometric properties of the pattern into account, the left-hand thread pattern and the right-hand thread pattern have the geometric characteristics of both the lined pattern and the ringed pattern. To conclude, a pattern perpendicular to the movement direction during the acupuncture manipulation creates more stimulation. These results have significance for future needle design.

ABSTRACT

ObjectiveTo investigate the intestinal absorption characteristics of multi-index components in Danggui Buxuetang with drug absorption simulating system (DASS) established by everted intestinal sac model. MethodThe intestinal absorption solution at different time points after administration of Danggui Buxuetang was collected and detected by high performance liquid chromatography (HPLC), acetonitrile (A)-0.2% glacial acetic acid solution (B) was used as the mobile phase for gradient elution (0-16 min, 15%-23%A; 16-20 min, 23%-28%A; 20-25 min, 28%-30%A; 25-30 min, 30%A; 30-35 min, 30%-65%A; 35-45 min, 65%-95%A), the detection wavelength was 302 nm. HPLC fingerprint of intestinal absorption solution was established and the common peak was calibrated, and the relative cumulative absorption rate of each index component was calculated. The relative cumulative absorption curves of components were fitted with various mathematical models by DDSolver 1.0 to explore the absorption law of different components. ResultThe absorption process of C2 (calycosin-7-glucoside) and C6 in Danggui Buxuetang was in line with zero-order equation, C9 was best fitted by Weibull equation, and the remaining 7 components were in line with Makoid-Banakar equation. C1 with C2, C3, C5, C7 and C10, C2 with C5 and C7, C3 with C4, C5, C7 and C10, C4 with C6 and C10, C5 with C7, C6 with C10, C7 with C10, C8 with C9 were absorbed simultaneously during the absorption process. With the prolongation of time, the overall cumulative absorption rate of Danggui Buxuetang increased. At 120 min, the overall cumulative absorption rate of Danggui Buxuetang exceeded 38%, and reached 49.14% at 180 min. ConclusionTen ingredients in Danggui Buxuetang are absorbed in the jejunum, but absorption law of various components is different, which shows that the intestinal absorption of compound preparations of traditional Chinese medicine (TCM) has multiple characteristics. Intestinal absorption study of TCM compound preparations with chemical composition as the index can reveal some of its absorption law, but it is not complete.

ABSTRACT

Objective: To analyze the safety and efficacy of combined left atrial appendage (LAA) and patent foramen ovale (PFO) closure in adult atrial fibrillation (AF) patients complicating with PFO. Methods: This study is a retrospective and cross-sectional study. Seven patients with AF complicated with PFO diagnosed by transesophageal echocardiography (TEE) in Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences from June 2017 to October 2020 were selected. Basic data such as age, gender and medical history were collected. The atrial septal defect or PFO occluder and LAA occluder were selected according to the size of PFO, the ostia width and depth of LAA. Four patients underwent left atrial appendage closure(LAAC) and PFO closure at the same time. PFO closure was performed during a one-stop procedure of cryoablation combined with LAAC in 2 patients. One patient underwent PFO closure at 10 weeks after one-stop procedure because of recurrent transient ischemic attack (TIA). All patients continued to take oral anticoagulants. TEE was repeated 8-12 weeks after intervention. In case of device related thrombus(DRT), TEE shall be rechecked 6 months after adjusting anticoagulant and antiplatelet drug treatment. Patients were follow-up at 1, 3, 6, 12, 24 months by telephone call, and the occurrence of cardio-cerebrovascular events was recorded. Results: Among the 7 patients with AF, 2 were male, aged (68.0±9.4) years, and 3 had a history of recurrent cerebral infarction and TIA. Average PFO diameter was (3.5±0.8)mm. Three patients were implanted with Watchman LAA occluder (30, 30, 33 mm) and atrial septal defect occluder (8, 9, 16 mm). 2 patients were implanted with LAmbre LAA occluder (34/38, 18/32 mm) and PFO occluder (PF1825, PF2525). 2 patients were implanted with LACbes LAA occluder (24, 28 mm) and PFO occluder (PF2525, PF1825) respectively. The patients were followed up for 12 (11, 24) months after operation. TEE reexamination showed that the position of LAA occluder and atrial septal defect occluder or PFO occluder was normal in all patients. DRT was detected in 1 patient, and anticoagulant therapy was adjusted in this patient. 6 months later, TEE showed that DRT disappeared. No cardiovascular and cerebrovascular events occurred in all patients with AF during follow-up. Conclusions: In AF patients complicated with PFO, LAAC combined with PFO closure may have good safety and effectiveness.

ABSTRACT

Objective:To analyze the safety and efficacy of left atrial appendage closure(LAAC)with Watchman in patients ≥85 years with atrial fibrillation(AF).Methods:515 elderly patients with atrial fibrillation, including 73 patients aged 85 years or older(85~91), who had undergone Watchman LAAC at Zhoupu Hospital affiliated to Shanghai Health Medical College from August 2016 to December 2020, were retrospectively analyzed.Of those ≥85 years, 44(60.3%)with transesophageal echocardiography records were assigned to the elderly group.Fifty-three patients aged 60 to 65 were selected as the control group.Differences in baseline data, intraoperative conditions, antithrombotic treatment plans and 1-year follow-up prognosis were compared between the two groups.Results:Compared with the control group, there was no difference in AF types, history of ischemic stroke/transient ischaemic attack(all P>0.05), but there were higher incidences of coronary heart disease and renal insufficiency, more severe heart failure, higher CHA 2DS 2-VASC(6.0±1.5 vs.3.6±1.5), HAS-BLED(3.2±1.2 vs.2.3±1.3)scores( t values were 7.682 and 3.871, respectively, P<0.05), and a lower one-stop surgery rate(6 cases or 13.6% vs. 27 cases or 50.9%, χ2=10.517, P<0.05)in the advanced age group.There was no difference in the diameter of the Watchman device, rate of device replacement, compression percentage and residual flow between the two groups during the perioperative period.The incidences of device-related thrombosis were 4.5%(2/44)and 3.8%(2/53)for the advanced age group and the control group, respectively, but the difference was not statistically significant( P>0.05). During the 12-month follow-up, there were no cases of ischemic stroke or intracerebral hemorrhage.Three died of heart failure and 1 died of cancer. Conclusions:LAAC with Watchman is safe and effective for patients over 85 years with AF, but the decision on the procedure should be based on careful assessment of patients' cardiac and renal function and general health.

ABSTRACT

Objective:To systematically review the relationship between the sepsis-induced myocardial dysfunction and hypertension.Methods:PubMed, Embase, Cochrane Library, China National Knowledge Internet (CNKI), China Biology Medicine (CBM) and Wanfang were searched both with Chinese and English keywords from the establishment of the database to January 2022 on the correlation between sepsis-induced myocardial dysfunction and hypertension. Newcastle-Ottawa Quality Assessment Scale (NOS) was used to evaluate the literature quality, and Stata 12.0 software was used to perform meta-analysis on the included literature.Results:After screening, 16 literatures were included, a total of 3 758 subjects was involved. Meta-analysis results showed that patients with hypertension had a higher incidence of sepsis-induced myocardial dysfunction, and the results were statistically significant. Subgroup analysis and sensitivity analysis suggested stable results.Conclusions:Hypertension is a risk factor for sepsis-induced myocardial dysfunction, and the results are statistically significant. Early intervention may improve the prognosis of septic patients.

ABSTRACT

Graves disease(GD) is the most common cause of hyperthyroidism in children.GD is an autoimmune thyroid disease which is based on genetic susceptibility and exacerbated by environmental factors including infection, toxin, drugs and stress.Antithyroid drugs(ATD) are the first-line treatment for GD in children.However, many children relapsed after discontinuing ATD, and the relapse rate between different children varied.Till now, exact cause has not been clarified.Previous studies prove that sex, age, micro-element, goiter size, thyroid hormone level, TRAb level, duration of ATD treatment and genetics may affect prognosis of pediatric GD.Yet predictors precious studies identified were variable.

ABSTRACT

BACKGROUND@#Core muscle functional strength training (CMFST) has been reported to reduce injuries to the lower extremity. However, no study has confirmed whether CMFST can reduce the risk of low back pain (LBP).@*OBJECTIVE@#This study identified the effects of CMFST on the incidence of LBP in military recruits.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#We performed a prospective, open-label, randomized, controlled study in a population of young healthy male naval recruits from a Chinese basic combat training program. Participants were randomly assigned to either the core group or the control group. In additional to normal basic combat training, recruits in the core group underwent a CMFST program for 12 weeks, while recruits in the control group received no extra training.@*MAIN OUTCOME MEASURES@#At the beginning of the study and at the 12th week, the number of participants with LBP was counted, and lumbar muscle endurance was measured. In addition, when participants complained of LBP, they were assessed using the visual analog scale (VAS) and Roland Morris Disability Questionnaire (RMDQ).@*RESULTS@#A total of 588 participants were included in the final analysis (295 in the core group and 293 in the control group). The incidence of LBP in the control group was about twice that of the core group over the 12-week study (20.8% vs 10.8%, odds ratio: 2.161-2.159, P < 0.001). The core group had better lumbar muscle endurance at 12 weeks than the control group ([200.80 ± 92.98] s vs [147.00 ± 84.51] s, P < 0.01). There was no significant difference in VAS score between groups, but the core group had a significantly lower RMDQ score at week 12 than the control group (3.33 ± 0.58 vs 5.47 ± 4.41, P < 0.05).@*CONCLUSION@#This study demonstrated that the CMFST effectively reduced the incidence of LBP, improved lumbar muscle endurance, and relieved the dysfunction of LBP during basic military training.

ABSTRACT

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.
