ABSTRACT

The incidence of occupational injury accidents in the metallurgy and mechanical manufacturing industries remains high, posing risks not only to the safety and health of workers but also causing heavy economic burdens to enterprises and families. The occupational injury accidents in metallurgy and mechanical manufacturing industries were caused by the following six items: human factors, machine factors, building factors, raw material factors, environmental factors, and management factors. The types and body parts of occupational injury accidents varied among different industries due to the nature of the occupation and working environment. Occupational injury accidents were both sudden and preventable. Currently, comprehensive intervention measures for occupational injury accidents at China and abroad included safety education, improving work environments, optimizing building layout and facilities, and enhancing safety management capabilities. Effective and feasible intervention measures for occupational injury accidents should be based on the characteristics and causes of occupational injury accidents in each industry, and should include corresponding interventions for workers, machines, buildings, raw materials, environment, and management.

ABSTRACT

ObjectiveTo analyze the results of fit testing and its influencing factors on half-mask respirator among workers exposed to organic solvents. Methods A total of 84 workers exposed to organic solvents were selected as the research subjects using a convenience sampling method. The qualitative fit test apparatus of respiratory protection was tested after the workers had put on the half-mask respirats, and 11 facial indicators of the subjects were measured. Results The overall pass rate of the respirator fit testing was 71.4% (60/84). The lowest pass rate was 63.1% (53/84), which occurred during bending movements of workers. The head width, minimum forehead width, face length, nose length, nose depth, head circumference and head length were higher in workers who passed respirator fit testing, compared with those in the failing group (all P<0.05). The result of binary logistic regression analysis showed that gender and face width were influencing factors of the respirator fit testing (both P<0.05). Female workers had a lower pass rate of the fit testing than male workers, and workers with larger face width had a lower pass rate in the fit testing. Conclusion Drastic movement may lead to a decrease in the seal of half-mask respirator of workers exposed to organic solvents. When providing half-mask respirator to workers exposed to organic solvents, employers need to pay attention to the fit of respirators of female works and those with larger face width to ensure the effectiveness of respiratory protection for workers.

ABSTRACT

ObjectiveTo explore the protective effect of hearing protectors worn by noise-exposed workers and its influencing factors. Methods A total of 329 occupational noise-exposed workers were selected as the research subjects by judgment sampling method. A questionnaire survey on the use of ear protectors and individual suitability tests was conducted. Intervention was carried out for those whose personal attenuation rating (PAR) did not pass the baseline standard. Results The median (M) and the 25th and 75th percentiles of baseline PAR were 17.0 (5.0, 22.5) dB. The baseline PAR of the workers who were male, aged 25-<35 years, with a working experience of 5-<15 years, with a college degree or above, wearing ear protectors for 5-<15 years, knowing the right way to wear ear protectors, and workers who wore ear protectors correctly during work was relatively high (all P<0.01). The unqualified rate of baseline PAR of the study subjects was 32.8%. The unqualified rate of baseline PAR of workers in automobile manufacturing enterprises was lower than that of workers in plastic enterprises and textile enterprises (9.2% vs 43.6%, and 9.2% vs 50.0%, both P<0.01). The M of the 108 unqualified worker on baseline PAR was improved after intervention (22.0 vs 1.0 dB, P<0.01). The rates of knowing the right way to wear ear protectors, wearing ear protectors correctly during work, and receiving training on wearing ear protectors correctly for the research subjects were 88.1%, 84.8%, and 86.6%, respectively. Workers in automobile manufacturing enterprises and plastic enterprises had higher rates of knowing the right way to wear ear protectors, wearing ear protectors correctly during work, and receiving training on wearing ear protectors correctly than those in textile enterprises (all P<0.01). Conclusion Gender, age, working experience, education level, duration of wearing ear protectors, knowledge and use of ear protectors correctly are influencing factors of the protective effect of ear protectors for noise-exposed workers.

ABSTRACT

The complex chemical composition and limited research ideas of traditional Chinese medicine (TCM) have led to the unclear material basis and mechanism of the medicinal effects, which is a common problem hindering the modernization of TCM in China. The introduction of computer virtual technology has provided a new perspective for TCM research. In this study, we established the research method of structure-activity omics to study the relationships between the structures and effects of different compounds in TCM based on the chemical structures of TCM components and to analyze and predict the material basis and multitarget synergistic mechanism of TCM. Furthermore, a structure-activity omics study was carried out with the anti-inflammatory and analgesic effects of Qizhi Weitong granules as an example. This study provides support for screening the pharmacodynamic components and analyzing the active ingredients of TCM and gives insights into the research on the material basis and mechanism of compound efficacy and the development of lead compounds of TCM, thus promoting the modern research and the innovative development of TCM.

ABSTRACT

ObjectiveTo identify the pharmacodynamic substances for the anti-inflammatory and analgesic effects of Bupleuri Radix by structure-activity omics. MethodA mouse model of pain was established with formaldehyde to examine the anti-inflammatory and analgesic effects of saikosaponins in vivo. The core targets of the active components in Bupleurum Radix for the anti-inflammatory and analgesic effects were screened from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Online Mendelian Inheritance in Man (OMIM), and Search Tool for Recurring Instances of Neighbouring Genes (STRING). The key core targets with high binding affinity were screened based on the comprehensive score in the molecular docking between different types of saikosaponins and core targets. The structure-activity relationship was discussed and analyzed based on the binding of compounds to pharmacodynamic targets. ResultSaikosaponins alleviated the foot swelling induced by formaldehyde and reduced the content of prostaglandin E2 (PGE2) in the mouse model, showcasing a significant inhibitory effect on the inflammatory pain caused by PGE2. Nine components and 39 targets of saikosaponins, as well as 3 074 targets of anti-inflammatory and analgesic effects were screened out, and 22 common targets shared by saikosaponins and the effects were obtained as the direct targets. The protein-protein interaction (PPI) analysis showed that the main active components of Bupleurum Radix were saikosaponins a, b1, b2, b3, c, d, e, f, and v, and the key targets were fms-related receptor tyrosine kinase 1 (FLT1), kinase insert domain receptor (KDR), fibroblast growth factor 2 (FGF2), vascular endothelial growth factor A (VEGFA), and signal transducer and activator of transcription 3 (STAT3). Molecular docking between saikosaponins and the top 5 targets with high degrees in PPI network analysis revealed 25 highly active docks, including 6 docks with scores of 5-6 and 18 docks with scores above 6. ConclusionThis study adopted structural-activity omics to analyze the material basis for the anti-inflammatory and analgesic effects of Bupleuri Radix in vivo, providing new ideas and methods for identifying the pharmacodynamic substances in traditional Chinese medicine.

ABSTRACT

ObjectiveTo explain the pharmacodynamic substances of Aurantii Fructus flavonoids that exert anti-inflammatory and analgesic effects using a structure-activity omics approach. MethodOn the basis of the previous in vitro pharmacological screening conducted by the research team, an in vivo pharmacological study of Aurantii Fructus flavonoids was carried out. Core targets of the anti-inflammatory and analgesic active components of flavonoids of Aurantii Fructus were identified using various network databases, including the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), the Online Mendelian Inheritance in Man (OMIM), and the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING). Computer-aided virtual screening technology was used to dock different types of Aurantii Fructus flavonoids with core targets. The key core targets with high binding activity were selected based on the comprehensive scores of each target and the active structures. Using these targets as bridges, the structures of one or more types of chemical components in Aurantii Fructus were closely linked to pharmacological effects. The structure-activity relationship between the clear pharmacodynamic compounds and their effects was explored through the binding patterns of various structures with pharmacodynamic targets. ResultAurantii Fructus flavonoids demonstrated significant anti-inflammatory and analgesic effects on dextran sulfate sodium (DSS)-induced colitis in mice, which could improve symptoms and significantly reduce the levels of inflammatory factors interleukin-6 (IL-6) and interleukin-1β (IL-1β)(P<0.05). Twelve active components of Aurantii Fructus flavonoids were identified and categorized into nine dihydroflavonoids and three flavonoids based on their structures of the parent nuclei. Through Venn analysis, 167 anti-inflammatory and analgesic targets for Aurantii Fructus were identified. Based on degree value and molecular docking comprehensive scores, prostaglandin-endoperoxide synthase 2(PTGS2) and mitogen-activated protein kinase 3(MAPK3) were selected for further structural analysis. Structural analysis revealed that components containing glycoside structures exhibited higher binding activity with anti-inflammatory and analgesic targets. ConclusionThis study utilized a structure-activity omics approach based on in vivo pharmacodynamic experiments to analyze the material basis of the anti-inflammatory and analgesic effects of Aurantii Fructus flavonoids. The structure-activity omics approach provides new ideas and methods for elucidating the pharmacodynamic substances of Chinese medicine.

ABSTRACT

OBJECTIVE To standardize the English translations of the current Chinese patent medicine (CPM) instructions in order to increase its English translation quality and improve its readability. METHODS In an attempt to standardize its English translation, 64 CPM instructions were collected as samples for translation projects in Trados, using its two core functions of translation memory and terminology, combined with pre-editing (PRE) and post-editing (PE) skills. RESULTS The results showed that translation projects had up to 21.65% perfect match. Based on translation project practice, it is proposed to use the free translation or transcreation plus transliteration method to translate product names of CPM, and apply two human-computer interaction translation modes:“ machine translation (MT)+computer-assisted translation (CAT)+PE” and “PRE+MT+CAT+PE”, which are adopted in the translation of weak literary sections and strong literary sections, respectively. CONCLUSIONS The application of CAT not only improves the translation quality and the translation mode, reduces the translation cost, and maintains the consistency and style of the translation, but also accumulates language assets for future use, providing a novel reference for translating traditional Chinese medicine literature.

ABSTRACT

Objective To compare the efficacy of common clinical interventions in the treatment of cervical high-risk (HR) HPV infection based on Bayesian network meta-analysis. Methods Randomized controlled trials (RCTs) about common clinical interventions for cervical HR-HPV infection were searched in PubMed, Web of Science, Embase, The Cochrane Library, CBM, CNKI, Wanfang Data, and VIP databases from inception to July 31, 2021 using specific inclusion and exclusion criteria. The quality of the included studies was evaluated in accordance with the Cochrane systematic review manual. Meta-analysis was performed with Stata16 and RevMan5.3 software. Results Seventy-three RCTs were included, involving 3642 patients and eight treatment methods. Network meta-analysis showed that in the three months after treatment, the negative conversion rate was in the order: PTL > anti-HPV BPD > ALA-PDT > Nr-CWS > BFKS > CSJZS > rhIFNα-2b > FUO. In the six months after treatment, the negative conversion rate was in the order: Nr-CWS > ALA-PDT > PTL > anti-HPV BPD > BFKS > rhIFNα-2b > FUO > CSJZS. In the nine months after treatment, the negative conversion rate was in the order: PTL > ALA-PDT > BFKS > anti-HPV BPD > rhIFNα-2b > FUO. IN the 12 months after treatment, the negative conversion rate was in the order: Nr-CWS > ALA-PDT > anti-HPV BPD > PTL > BFKS > rhIFNα-2b > FUO > CSJZS. Conclusion In terms of HPV negative conversion rate, Nr-CWS and PTL are more effective and currently ideal compared with the other treatments. Owing to the quality of the evidence, the above conclusions must be confirmed by future high-quality studies.

ABSTRACT

OBJECTIVE@#Hypertrophic scars (HS) are a variety of skin tissue fibrosis disease that occurs in human skin, the effective therapeutic method of which is still inaccessible up to now. As a bioactive constituent of a well-known medical plant, Salvia miltiorrhiza (Danshen in Chinese), tanshinone IIA (TSA) is reported to inhibit cell proliferation in HS. Therefore, the aim of this study was to prepare TSA self-soluble microneedles to strengthen its dermal retention and break through the difficulty of significantly thickening epidermal connective tissue and stratum corneum at the HS site. The possible mechanism of action in suppressing HS was studied using human skin fibroblasts (HSF).@*METHODS@#Tanshinone IIA self-dissolving microneedles (TSA-MN) was prepared using a negative mold casting method. The prescription process of microneedle was optimized by Box-Behnken effect surface method. Different media were selected to investigate the ability of transdermal absorption and in vitro release. Furthermore, according to Cell Counting Kit-8 (CCK8) method as well as the Western blot method, the effect of TSA-MN on the biological characteristics of HSF was investigated.@*RESULTS@#With remarkable slow release effect and dermal retention, the release and transdermal properties of TSA-MN in vitro were better than both TSA and ordinary dosage forms. Its effect of HSF confirmed the essential decrease in cell motility during cell proliferation and cell migration in vitro, which plays a significant role in down-regulating the secretion of transforming growth factor-β1 (TGF-β1) in HSF and increasing the expression level of Smad7.@*CONCLUSION@#The prepared TSA self-soluble microneedles is helpful in solving the problem of hypertrophic scars, with a stable dermal retention effect after process optimization.

ABSTRACT

Objective To investigate the relationship between corneal hysteresis(CH)and retinal nerve fiber layer(RNFL)thickness in patients with glaucoma.Methods In this study,186 eyes of 133 patients with open-angle glaucoma who attended the ophthalmology department of our hospital were included,with a follow-up of(3.8±0.8)years and an average of 9 visits.The CH measurements were acquired using the Ocular Response Analyzer,and RNFL thickness was measured at each follow-up using spectral domain optical coherence tomography.All statistical analyses were performed with Stata software.Univariate and multivariable linear regression models were used to investigate the relationship between age,baseline CH,intraocular pressure(IOP),central corneal thickness(CCT)and RNFL thickness.Results The aver-age baseline CH was(9.2±1.8)mmHg(1 kPa=7.5 mmHg),average baseline RNFL thickness was(76.4±18.1)μm,the average baseline IOP was(13.8±3.7)mmHg,and the average baseline CCT was(533±42)μm.Univariate model analysis showed that the baseline CH had a positive correlation with RNFL thickness(P<0.05).The lower the CH,the thinner the RNFL.For every 1 mmHg reduction in CH,the thickness of RNFL was reduced by 0.13 μm,indicating that CH may be involved in the occurrence and development of glaucoma.The univariate model analysis also showed that there was a negative correlation between IOP and RNFL thickness(P<0.05).The higher the IOP,the thinner the RNFL.However,there was no significant correlation between age,CCT and RNFL thickness(both P>0.05).The multivariate model analy-sis showed that there was a positive correlation between baseline CH and RNFL thickness during the follow-up,excluding the influence of age,IOP and CCT(P<0.05).For every l mmHg reduction in CH,the thickness of RNFL was reduced by 0.13 μm.Conclusion There is a positive correlation between baseline CH and RNFL thickness in glaucoma.The lower the CH,the thinner the RNFL.Low CH may be a risk factor for the progression of glaucoma.

ABSTRACT

Objective:To evaluate the incidence, clinical characteristics and prognosis of second primary malignancies (SPMs) among patients with hypopharyngeal carcinoma (HPC) in real-world analysis.Methods:A total of 594 HPC patients admitted to Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from 2010 to 2018 were retrospectively analyzed.The incidence and clinical characteristics of HPC patients complicated with SPMs were analyzed. Clinical efficacy was compared among different groups.Results:With a median follow-up time of 66.9 months, SPMs were present in 36.4% (216/594) of HPC patients: 22.2% (132/594) were synchronous and 14.1% (84/594) were metachronous. The upper aerodigestive tract was the most common involved region. Compared with patients without SPMs, patients with synchronous and metachronous carcinoma in situ had similar 5-year overall survival (OS) of 42.2% vs. 44.5% ( P=0.958) and 62.2% vs. 44.5% ( P=0.240), respectively. Patients with synchronous invasive SPMs had a worse 5-year OS of 27.2% vs. 44.5% in their counterparts without SPMs ( P=0.001). Patients with metachronous invasive SPMs had similar 5-year OS of 50.2% vs. 44.5% in their counterparts without SPMs ( P=0.587). SPMs accounted for 42.5% of total death in metachronous invasive SPMs group. Conclusions:Patients with HPC have a high probability of developing SPMs. Moreover, the incidence of complicated with esophageal/gastric carcinoma in situ or metachronous SPMs exerts no effect on prognosis, while the occurrence of synchronous SPMs significantly affectes the prognosis of patients. However, the incidence of SPMs is still one of the main death causes in metachronous invasive SPMs group.

ABSTRACT

OBJECTIVE@#To explore the diagnostic yield of bronchoscopic rapid on-site evaluation (B-ROSE) in patients with severe invasive bronchopulmonary aspergillosis (IBPA) and provide evidence for starting antifungal treatment before microbiological results were available.@*METHODS@#A prospective cohort study was conducted to select patients with severe pneumonia suspected of IBPA admitted to the respiratory intensive care unit (RICU) in the First Affiliated Hospital of Xinjiang Medical University from June 2014 to June 2022, and those who were primarily infected with other pathogens (such as bacteria, Mycobacterium tuberculosis) at admission were excluded. Whether the antifungal treatment was initiated or not on the basis of the bedside B-ROSE, the B-ROSE was administered as soon as possible within 24 hours after admission to RICU. The current international definition of invasive aspergillosis was used as the gold diagnostic standard, the diagnostic accordance rate, the sensitivity and specificity of B-ROSE were calculated respectively, and the receiver operator characteristic curve (ROC curve) was also plotted, to evaluate the predictive value in diagnosing IBPA.@*RESULTS@#A total of 176 patients with severe pneumonia suspected of IBPA were included in the study. According to international diagnostic standards, there were 81 cases of IBPA and 95 cases of non-IBPA. According to the early diagnosis of B-ROSE, there were 89 cases of IBPA and 87 cases of non-IBPA. The diagnostic accordance rate of B-ROSE was 84.09% (148/176), the area under the ROC curve for B-ROSE in diagnosing severe IBPA was 0.844, the 95% confidence interval (95%CI) was 0.782-0.905, the sensitivity was 87.65%, the specificity was 81.05%, the positive predictive value was 79.78%, the negative predictive value was 88.51%, the rate of underdiagnosis was 12.35% (10/81), and the rate of misdiagnosis was 18.95% (18/95). Compared with the true negative group, the proportion of long-term (≥ 14 days) use of glucocorticoid [70.0% (7/10) vs. 9.1% (7/77), P < 0.01] and the proportion of cases with diabetes [40.0% (4/10) vs. 10.4% (8/77), P < 0.05] were significantly higher in the false negative group (underdiagnosis group). However, B-ROSE of both groups showed mucosal bleeding, congestion and edema [100.0% (10/10) vs. 94.8% (73/77), P > 0.05], indicating that acute mucosal inflammation was non-characteristic. Compared with the true positive group, the proportion of long-term (≥ 14 days) use of glucocorticoid in the false positive group (misdiagnosis group) was significantly reduced [33.3% (6/18) vs. 60.6% (43/71), P < 0.05]. The B-ROSE results showed the proportion of cases with mucosal white spots, black plaques and pseudomembrane was significantly reduced [16.7% (3/18) vs. 52.1% (37/71), P < 0.01] in the misdiagnosed group, which suggest that cases of long-term use of glucocorticoid and cases with B-ROSE showing mucosal white spots, black plaques and pseudomembrane were less likely to be misdiagnosed. The main diseases that were easily misdiagnosed as IBPA included pulmonary tuberculosis (38.9%, 7/18), inflammatory lung adenocarcinoma (27.8%, 5/18) and pulmonary vasculitis (16.7%, 3/18).@*CONCLUSIONS@#Before obtaining microbiological evidence, B-ROSE can assist in decision-making of early anti-aspergillus treatment for severe IBPA. This method is prompt, simple, and has high accuracy and reliability. If B-ROSE lacks characteristic manifestations, especially for severe pneumonia in patients with long-term use of glucocorticoid or diabetes, attention should be paid to the underdiagnosis of IBPA. Diseases such as lung tuberculosis, inflammatory lung adenocarcinoma and lung vasculitis should be vigilant against misdiagnosis as IBPA.

ABSTRACT

Objective:This study aimed to evaluate the clinical features and treatment outcomes of the value of response-adapted treatment following radiotherapy and induction chemotherapy follwing subsequent comprehensive therapy in patients with resectable locally advanced hypopharyngeal carcinoma. Methods:This cohort study was conducted from September 2010 to September 2020 in our hospital, 231 patients pathologically confirmed stage Ⅲ and ⅣB resectable locally advanced hypopharyngeal carcinoma included. For the IC-directed ART strategy, IC is used to select good candidates to receive radical RT or CCRT, and others undergo surgery. He response-adapted strategy was determined based on the primary tumor response, which was evaluated at a dose of 50 Gy. If the response reached complete response or partial response(more than 80% tumor regression), patients received radical RT or CCRT; otherwise, they received surgery, if possible, at 4 to 6 weeks after RT. The end points of the study were OS(overall survival), progression free survival(PFS), locoregional recurrence-free survival(LRRFS) and LDFS. Results:In IC-directed group, 75.0%(57/76) patients reached PR after 2 cycles of induction chemotherapy. While in RT-directed group, 70.3%(109/155) patients reached large PR at dose of 50 Gy. The median interquartile range follow-up period of the whole cohort was 63.8 months. The 5-year OS, PFS, LRRFS and SFL of the whole cohort were 47.9%、39.6%、44.3% and 36.2%, respectively. In evaluations based on the different treatment strategies, the 5-year OS and SFL were 51.3% versus 37.0%(HR 0.67; 95%CI 0.43-1.05; P=0.07) and 27.8% versus 39.8%(HR 0.68; 95%CI 0.46-0.99; P=0.04) between IC-directed and RT-directed groups. In additional, surgery complications did not significantly differ between these two groups. Conclusion:In this cohort study, the response-adapted strategy based on an early RT response facilitated better treatment tailoring, and higher laryngeal preservation compared with IC-directed strategies. This approach could provide a feasible laryngeal preservation strategy in patients with resectable locally advanced hypopharyngeal carcinoma.

The mean score for recognizing the risk of HIV infection was 12.41±3.09, for HIV antibody test self-efficiency was 17.07±2.12, and for perceived social supports was 17.42±2.41. A total of 287 respondents received HIV antibody tests (95.67%), including 192 participants receiving repeated HIV antibody tests (64.00%). Multivariable logistic regression analysis showed that age of >18 years for the first homosexual sex behavior (OR=0.404, 95%CI: 0.223-0.734), receiving STDs tests in the past six months (OR=3.896, 95%CI: 2.145-7.076), sex role as receptive partners or both receptive and insertive partners (OR=0.502, 95%CI: 0.275-0.917), satisfying with HIV antibody test services (OR=2.955, 95%CI: 1.311-6.660), and high score for HIV antibody test self-efficiency (OR=1.149, 95%CI: 1.005-1.314) were factors affecting repeated HIV antibody tests among MSM.@*Conclusions@#The detection of repeated HIV antibody tests was 64.00% among MSM in Wuhan City in 2019, and age for the first homosexual behavior, STDs tests, sex role, evaluation of HIV antibody test services and self-efficiency of HIV antibody tests may be factors affecting repeated HIV antibody tests among MSM.

ABSTRACT

Objective:To investigate the relationship between the level of anti Mullerian hormone (AMH) and antral follicle count (AFC) and oocytes number in patients with in vitro fertilization (IVF). Methods:372 patients with primary infertility who received IVF and embryo transfer (IVF-ET) treatment in the Affiliated Hospital of Guizhou Medical University from January 2020 to December 2020 were prospectively selected as the study subjects. According to the oocytes obtained, the patients were divided into low ovarian response group (LOR group, the number of oocytes obtained ≤5, n=37), normal group (NOR group, the number of oocytes obtained was 6-15, n=292) and high ovarian response group (HOR group, the number of oocytes obtained >15, n=43). The levels of AMH and AFC in the three groups were observed. The relationship between AMH, AFC with LOR and HOR was observed by multivariate logistic analysis. The sensitivity, specificity, optimal cut-off value and area under the curve (AUC) of AMH and AFC for predicting LOR and HOR were calculated by receiver operating characteristic (ROC) curve. Results:There were significant difference in AMH, AFC and oocyte number among the three groups (all P<0.05). The AMH, AFC and oocyte number in NOR group were higher than those in LOR group, and AMH, AFC and oocyte number in HOR group were higher than those in LOR and NOR group (all P<0.05). The results of binary multivariate analysis showed that AFC and AMH were protective factors of LOR (all P<0.05), while AFC and AMH were risk factors of HOR ( P<0.05). The sensitivity and specificity of AMH and AFC in predicting LOR were 83.8% and 75.7%, 65.7% and 84.2%, respectively. The sensitivity of AMH or AFC positive as the standard for predicting LOR was 94.6%, and the specificity of AMH and AFC was 91.6%. The sensitivity and specificity of positive AMH and AFC in predicting HOR were 69.8% and 74.4%, 69.6% and 83.6%, respectively. The sensitivity of AMH or AFC positive as the standard for predicting HOR was 93.0%, and the specificity of AMH and AFC positive as the standard for predicting HOR was 93.0%. Conclusions:AMH and AFC are significantly correlated with oocyte number in patients with primary infertility. Flexible application of AMH and AFC is beneficial to better predict the number of oocytes obtained, which provides a reference for clinical development of individualized ovarian stimulation program.
