ABSTRACT

This study aimed to understand the differences in clinical, epidemiological, and laboratory features between the new coronavirus disease 2019 (COVID-2019) and influenza A in children. Data of 23 hospitalized children with COVID-19 (9 boys, 5.7 ± 3.8 years old) were compared with age- and sex-matched 69 hospitalized and 69 outpatient children with influenza A from a hospital in China. The participants' epidemiological history, family cluster, clinical manifestations, and blood test results were assessed. Compared with either inpatients or outpatients with influenza A, children with COVID-19 showed significantly more frequent family infections and higher ratio of low fever ( 39 °C), nasal congestion, rhinorrhea, sore throat, vomiting, myalgia or arthralgia, and febrile seizures. They also showed higher counts of lymphocytes, T lymphocyte CD8, and platelets and levels of cholinesterase, aspartate aminotransferase, lactate dehydrogenase, and lactic acid, but lower serum amyloid, C-reactive protein, and fibrinogen levels and erythrocyte sedimentation rate, and shorter prothrombin time. The level of alanine aminotransferase in children with COVID-19 is lower than that in inpatients but higher than that in outpatients with influenza A. Pediatric COVID-19 is associated with more frequent family infection, milder symptoms, and milder immune responses relative to pediatric influenza A.

ABSTRACT

BACKGROUND@#Intensive therapy with disease modifying anti-rheumatic drugs (DMARDs) has been reported to improve the outcomes of rheumatoid arthritis (RA). However, real-world study on the effect of intensive therapy on RA sustained remission is still lacking. This study aimed to investigate the outcome of sustained intensive DMARD therapy (SUIT) for RA in a real-world 5-year consecutive cohort.@*METHODS@#Based on a consecutive cohort of 610 out-patients with RA, remission of RA was assessed in 541 patients from 2012 to 2017, by dividing into SUIT, non-SUIT, and intermittent SUIT (Int-SUIT) groups. Changes in the disease activity scores were evaluated by 28-joint disease activity score based on erythrocyte sedimentation rate (DAS28-ESR), 28-joint disease activity score based on C-reactive protein (DAS28-CRP), and clinical deep remission criteria (CliDR). Cumulative remission rates between different groups were compared using Kaplan-Meier curves and predictive factors of sustained remission were identified by univariate and multivariate logistic regression analysis.@*RESULTS@#The remission rates of the SUIT group decreased from 12.0% (65/541) to 5.6% (20/359) based on DAS28-ESR, from 14.0% (76/541) to 7.2% (26/359) based on DAS28-CRP, and from 8.5% (46/541) to 3.1% (11/359) based on CliDR, respectively, with a gradually decreasing trend during the 5 years. The SUIT regimen led to a significantly higher cumulative remission rate than non-SUIT regimen based on DAS28-ESR (39.7% vs. 19.5%, P = 0.001), DAS28-CRP (42.0% vs. 19.6%, P = 0.001), and CliDR (24.5% vs. 8.7%, P = 0.001). The cumulative remission rates of patients treated with SUIT regimen were significantly higher than those treated with Int-SUIT regimen based on DAS28-ESR (39.7% vs. 25.7%, P = 0.043) and CliDR (24.5% vs. 14.2%, P = 0.047), but there was no significant difference between the two groups based on DAS28-CRP (42.0% vs. 27.4%, P = 0.066). Multivariate logistic regression analysis showed that the use of SUIT regimen was an independent favorable predictor according to different remission definitions (for DAS28-ESR: odds ratio [OR], 2.215, 95% confidence interval [CI]: 1.271-3.861, P = 0.005; for DAS28-CRP: OR, 1.520, 95% CI: 1.345-1.783, P = 0.002; for CliDR: OR, 1.525, 95% CI: 1.314-1.875, P = 0.013).@*CONCLUSION@#Sustained intensive treatment of RA is an optimal strategy in daily practice and will lead to an increased remission rate.

ABSTRACT

The development of Chinese medicine and Western medicine andrology is based on different social background and academic systems, either Chinese medicine or Western medicine andrology has their limitations, therefore, integration of Chinese and Western medicine (ICWM) andrology is in a great need. After more than 30 years of development, andrology has made great achievements in the construction of specialized academic association, holding academic conferences and publication of academic monographs, and the research progress on this field is mainly in the combination of disease and syndrome, microdifferentiation of symptoms and signs and basic research development. However, the comprehensive theoretic system of ICWM andrology has not yet established, and the related studies are still on the primary stage. In the future studies, great efforts still need to be made to expand the methods for the investigation of ICWM, and make innovations in the field of andrology.

ABSTRACT

In this paper, 2 cases of collagen Type Ⅲ glomerulopathy were analyzed. The clinical manifestations mainly included nephrotic syndrome, proteinuria, hypertension and renal dysfunction. One patient showed that the complement factor H-related protein 5 (CFHR5) gene was likely a disease-causing mutation. The pathological examination of renal tissues showed hyperplasia of mesangial matrix, sub-endothelial insertion, and double-track formation. Immunohistochemistry of Type III collagen was positive. Electron microscopy revealed that massive collagen fibers (40-70 nm in diameter) deposited in the mesangial matrix and basement membrane. As for the follow-up results, the normal renal function had kept steady and the proteinuria was moderate in 1 case treated with angiotensin Ⅱ receptor blocker. Due to other system disease, another case developed into acute kidney injury and then received hemodialysis. The clinical manifestations of collagen Type Ⅲ glomerulopathy was atypical, the light microscope pathological features were various, and the disease was mainly diagnosed by electron microscopy and immunohistochemistry.

ABSTRACT

OBJECTIVES@#To evaluate the value of thrombospond in Type I domain-containing 7A (THSD7A) and M-type phospholipase A2 receptor (PLA2R) in primary membranous nephropathy (PMN) and to explore the relationship between their antibody levels and prognosis.@*METHODS@#Renal tissues in 128 patients with membranous nephropathy in the Second Xiangya Hospital of Central South University were collected from February 2015 to August 2017, including 108 patients with primary membranous nephropathy (PMN group) and 20 patients with secondary membranous nephropathy (SMN) (SMN group). Indirect immunofluorescence method was used to detect the expression of PLA2R antigen in kidney tissues,and the glomerular expression of THSD7A antigen was examined by immunohistochemistry and indirect immunofluorescence. The serum levels of anti-PLA2R antibodies and THSD7A antibodies were also detected by ELISA. According to the results of PMN examination,the patients were also divided into a PLA2R-related membranous nephropathy group and a THSD7A-related membranous nephropathy group.@*RESULTS@#The positive rate of PLA2R in the renal tissues in the PMN group was higher than that in the SMN group (78% in the PMN group, 35% in the SMN group, <0.01),while the positive rate of anti-PLA2R antibody in the PMN group was also higher than that in the SMN group (50% in the PMN group, 25% in the SMN group, <0.05).The serum level of anti-PLA2R antibody was positively correlated with 24 h urine protein (=0.254, <0.05) and negatively correlated with serum albumin (=-0.236, <0.05). The expression of THSD7A was positive in glomeruli in 7 cases of the PMN group (6%) by immuno-histochemistry, and which was positive in 1case of the SMN group (5%).The serum levels of anti-THSD7A antibody in the PMN group were higher than those in the SMN group [(0.49±0.26) pg/mL in the PMN group,(0.34±0.27) pg/mL in the SMN group, <0.05]. There was no difference in the clinical characteristics between the PLA2R-related membranous nephropathy group and the THSD7A-related membranous nephropathy group.@*CONCLUSIONS@#PLA2R and THSD7A are the target antigen of PMN, and the associated autoantibodies are helpful for the differential diagnosis of PMN. The anti-PLA2R antibody levels can reflect the severity of the disease and evaluate the effect of treatment. The incidence of THSD7A membranous nephropathy is low, and monitoring the serum anti-THSD7A antibody levels can assess patients' condition and predict disease outcome.

ABSTRACT

ObjectiveThe role of human tumor-related calcium signal transductor 2 (TACSTD2) in promoting tumorigenesis has been noticed recently. We predicted the molecular structure and biological function of TACSTD2 by bioinformatic methods, in order to provide reference for further study of TACSTD2.MethodsThe homo sapiens TACSTD2 mRNA and protein amino acid sequences were obtained from the National Center for Biotechnology Information (NCBI) database. The bioinformatic methods were used to analyze the open reading frame(ORF) of TACSTD2, physicochemical properties, signal peptide and protein localization, subcellular localization, and prediction of transmembrane structure and secondary structure, tertiary structure, potential protein modification sites, domains, protein modification sites proteins, protein interacting with TACSTD2, biological functions of TACSTD2, and expression of TACSTD2 in human normal tissues and certain tumor types.ResultsAccording to the mRNA sequence of TACSTD2, there are 12 ORFs, and the longest is ORF1, with a total of 972bp, encoding 323 amino acids. The hydrophilic amino acid of TACSTD2 is more than that of hydrophobic amino acid, indicating that TACSTD2 belongs to hydrophilic protein. TACSTD2 is a highly conserved alkaline secreted protein with a transmembrane region both inside and outside the cytoplasm. The presence of nuclear localization signal(NLS) in the amino acid sequence of TACSTD2 suggests that TACSTD2 can locate in cell nucleus. TACSTD2 mainly distribute in cytoplasmic membrane, extracellular, nucleus and cytoplasm. The secondary structure prediction results showed that the main structure of TACSTD2 was random coil, followed by a α helix. TACSTD2 has 15 serine modification sites, 17 threonine modification sites, and 8 tyrosine modification sites. The TACSTD2 has protein interactions with Claudin(CLDN) protein family; and participating in signaling pathway such as cell surface receptor, cell proliferation, negative regulation of epithelial cell migration, and so on. Comparing with normal human tissues, its mRNA expression is up-regulated in most tumor types such as cervical cancer, lung cancer, thyroid cancer, uterine cancer, liver cancer, colorectal cancer.ConclusionAccording to the analysis of the structure and function of TACSTD2, TACSTD2 is highly-expression in multiple malignancies. It can participate in the process of proliferation, migration and adhesion of malignant tumor cells through cell surface receptor signaling pathways. This study provide reference for the further research about the function of TACSTD2.

ABSTRACT

Viral infections have always threatened human health. Broad-spectrum antiviral agents (BSAs) can either target host proteins that are essential for viral replication, or act on multiple viruses or multiple genotypes of the same virus. More importantly, BSAs could reduce the possibility of drug resistance. From the perspective of medicinal chemistry, this review summarizes recent advances in the research of broad-spectrum antiviral drugs with privileged structures or targeting specific targets in the viral life cycle.

ABSTRACT

Objective To evaluate the clinical effects of short-term (3-6 months) and long-term (12 months) dual antiplatelet therapy (DAPT) after the implantation of coronary drug-eluting stents (DES). Methods The eligibilities of the patients included stable angina, acute coronary syndrome and silent ischemia. The lesions were in a native coronary vessel. The clinical observation endpoints were all-cause death, cardiogenic death, myocardial infarction, stroke, stent thrombosis, target lesion revascularization, severe bleeding, and true adverse clinical events. The clinical observation endpoints were all-cause death, cardiogenic death, myocardial infarction, stroke, stent thrombosis, target lesion revascularization, severe bleeding, and true adverse clinical events. By searching Pubmed, Chinese biomedical literature and other Chinese and English databases and manual search, qualified randomized controlled studies were evaluated and data were extracted for meta-analysis. Results A total of 12 randomized controlled studies were conducted. Detsky scores were all greater than 5 points. There were a total of 25949 patients in the study with a follow-up rate of 97.9%. There were no significantly different in all cause death (OR = 0.86,95%CI 0.71-1.05,P = 0.14), cardiac death (OR = 0.94,95% CI 0.70-1.25,P = 0.67), stent thrombosis (OR = 1.36,95%CI 0.94-1.98,P = 0.11), stroke (OR = 1.01,95%CI 0.71-1.42,P = 0.98), target lesion revascularization (OR = 0.121,95%CI 0.94-1.55,P = 0.14),and true adverse clinical events (OR = 0.98,95%CI 0.83-1.14,P = 0.75). The incident rate of myocardial infarction during the follow-up period was higher in the short-term group than in the long-term group (OR = 1.27, 95% CI 1.02-1.59, P = 0.04). The proportion of severe bleeding in the long-term group increased significantly (OR = 0.69, 95% CI 0.50-0.95, P = 0.02). Asian population studies showed that all-cause mortality was higher in the long-term treatment group than in the short-term group (OR = 0.72, 95% CI 0.53-0.97, P = 0.03), and there was no significant difference in severe bleeding between the two groups. Conclusion According to the defined clinical observation endpoints, the short-term dual antiplatelet effect is not inferior to the long-term group. Seven asian group studies have shown that the long-term group has high all-cause mortality. It can not rule out the deviation and/or population caused by the small sample size or individual variation. The results need to be further verified. This result can be used as a clinical warning to adjust the dual antiplatelet cycle based on the individualized risk of bleeding and coronary lesions.

ABSTRACT

To investigate the association between chronic unpredictable mild stress (CUMS)-induced depressive-like behavior in rats and expressions of brain-derived neurotrophic factor (BDNF) and S100β in the hippocampal and prefrontal cortex. Rats were randomly assigned to three groups:saline control group,saline+CUMS group,and citalopram +CUMS group. CUMS was used for depression modeling in rats. Depressive-like behavior in rats were evaluated by open-field test,sucrose preference test,and novel object recognition test. S100β and BDNF expressions were tested by enzyme-linked immunosorbent assay. Rats in the saline+CUMS group had significantly lower score in sucrose preference [(52.48±13.14)%],basic motor tasks [(845.8±371.4)s],fine motor tasks [(565.6±211.9)s],and longer resting time [(282.6±11.8)s] compared to the control group [(84.30±6.15)% (=7.49,=0.000),(1239.1±281.6)s (=2.83,=0.008),(801.8±150.9)s (=3.05,=0.003),(268.2±12.8)s (=2.72,=0.001)]. Compared with the citalopram+CUMS group,rats from the saline+CUMS group also showed significantly lower results in sucrose preference [(80.55±11.31)%,=5.39,=0.000],basic motor tasks [(1156.4±314.7)s,=2.13,=0.031],and fine motor tasks [(736.1±150.0)s,=2.21,=0.008]. There were no significant differences in the expression of hippocampal and prefrontal BDNF between these two groups,but rats from the saline+CUMS group expressed significantly higher levels of S100β compared to rats from the citalopram+CUMS group [(13.22±2.23) ng/g (10.55±2.72) ng/g,=2.67,=0.014]. Pearson correlation analysis revealed that the expression of S100β was positively correlated with the expression of BDNF in the prefrontal cortex and hippocampus (=0.35,=0.034;=0.36,=0.034).The novel object recognition index was positively correlated with the expression of BDNF in the hippocampus(=0.38,=0.021),and the duration of fine-motor activities was negatively correlated with S100β in the prefrontal cortex (=-0.36,=0.037). Different types of depressive behaviors in rats induced by CUMS are associated with the selective expression of S100β and BDNF in two different brain cortex. S100β protein and BDNF may independently participate in the pathogenesis of depression.

ABSTRACT

Xiebaisan, which is one of the famous classical formulas in the Catalogue of Ancient Famous Classical Formulas (The First Batch) published by the National Administration of Traditional Chinese Medicine (TCM) in 2018, is derived from the Xiao' er Yaozheng Zhijue with definite clinical effect. By means of bibliometrics, 118 relevant ancient book data were collected, including 75 ancient books of TCM. It was found that the main symptoms of Xiebaisan had been expanded in the past dynasties. For example, the adaptive population of Xiebaisan had been extended from children to women and adults, and the scope of symptoms and signs had also been extended from pediatrics to internal medicine and gynecology. Meanwhile, the names, pathogenesis and syndromes of diseases are also described extensively, although the dosage ratio is different, the compatibility ratio of Mori Cortex, Lycii Cortex and Glycyrrhizae Radix et Rhizoma is relatively constant, and the decoction method is mostly followed by decocted power. At the same time, doctors in Ming and Qing dynasties have made a lot of general comments on explanation of this formula, but there is little controversy.

ABSTRACT

The research and development of classical famous prescriptions is an important way to actively promote the development of traditional Chinese medicine.It is particularly important to sort out the historical evolution of the composition of traditional famous prescriptions to make clear the origin,producing areas and concocting methods of traditional Chinese medicine,which is the source of ensuring the safety and efficacy.Through literature review,it is found that at present,the research of mulberry white skin focuses on chemical composition,pharmacological mechanism and modern clinical research,and there are few ancient literature studies.Therefore,based on the ancient literature,the author conducts a comprehensive textual research on mulberry bark from its name,origin,producing areas and concocting methods and other aspects,in order to provide literature reference for the research and development of the prescription involving mulberry bark in the classic prescription.Through research,we can know that there are more than 20 aliases of mulberry bark,and the most commonly used names in modern times are "sangbaipi""sanggenbaipi""sangpi",etc.In Tang and Song dynasties and before,mulberry bark was mainly composed of Morus alba var. alba and jisang,after Tang and Song dynasties,mulberry bark plant sources showed diversity,in modern times,Morus alba var. alba was gradually identified as the main medicinal species of mulberry bark.Therefore,it is suggested that Morus alba var. alba be selected as the plant source of mulberry bark.According to ancient books,mulberry trees are cultivated everywhere,with Jiangsu,Zhejiang and Sichuan as the best areas,and Henan and Anhui as the most popular areas in modern times.The conclusion of ancient and modern quality of mulberry bark is basically the same,the root skin is white,thick and sweet.The morden concocting methods of mulberry bark mainly include raw mulberry bark,honey mulberry bark and fried mulberry bark.According to the textual research of ancient literature,in addition to the above three kinds of medical specifications,there have been concocting methods without auxiliary materials,such as burning,baking and roasting,as well as concocting methods with auxiliary materials,such as bran roasting,rice swill soaking,honey wine roasting,etc.The concocting methods of mulberry bark used by the classical famous recipe should be selected in combination with specific drug provisions.

ABSTRACT

Objective:To investigate the value of post left atrium space index (PLASI) in the diagnosis of fetal isolated total anomalous pulmonary venous connection (TAPVC).Methods:Twenty-six cases of fetal isolated TAPVC were retrospectively analyzed as the TAPVC group and 243 normal fetuses were selected as the control group from October 2012 to April 2019 in the Consultation Center of Maternal-Fetus Medicine in Fetal Heart Disease in Beijing An Zhen Hospital. The width of the PLAS and the diameter of the descending aorta were measured in the four chamber view, and then the PLAS index (PLASI) (the width of the PLAS/the diameter of the descending aorta) was calculated. The relationships between the width of PLAS, the diameter of descending aorta and the PLASI and gestational age were analyzed. The difference of the PLASI between isolated TAPVC group and control group was analyzed, and ROC curve was used to analyze the sensitivity and specificity in identifying the isolated TAPVC fetuses and normal fetuses.Results:In the 243 normal fetuses in control group, both the width of the PLAS and the diameter of the descending aorta increased with gestational age ( r s=0.362, 0.648, P<0.05). There was no statistically significant correlation between the PLASI and gestational age ( r s=-0.065, P>0.05). The PLAS and the PLASI in isolated TAPVC group were all significantly higher than those in control group ( t=26.31, 34.90, P<0.01). Based on the ROC curve analysis, when the cutoff value was set to 3.6 mm, the sensitivity and specificity of PLAS in identifying isolated TAPVC and normal fetuses were 97.5% and 100%, respectively. When the cutoff value was set to 1.1, the sensitivity and specificity of PLASI in identifying isolated TAPVC and normal fetuses were 100% and 100%, respectively. Conclusions:The PLASI is a sensitive parameter in identifying the isolated TAPVC, which is helpful for the rapid screening of the isolated TAPVC.

ABSTRACT

Alzheimer's disease (AD) is a degenerative disease of the central nervous system characterized by progressive cognitive and behavioral disorders.Clinical manifestations include memory impairment, aphasia, apraxia, impaired visual spatial function, executive power, decreased computing power, personality and behavior changes and so on.At present, the incidence of dementia is increasing year by year, causing a huge social burden, and there is still no effective treatment.Therefore, many scholars try to prevent and delay the occurrence of cognitive impairment through the identification and control of risk factors.Combining with previous studies, nap is helpful for the maintenance and consolidation of memory.This article discusses the effect of nap on cognitive function and its related mechanisms.First, nap can improve cognitive function, but it depends on the length, the frequency of the nap, and the difficulty of the task.Second, the effect of nap on cognition may be through inflammatory response, neuroendocrine, Aβ and gene polymorphism.In addition, this paper also proposes future research prospects in terms of standardized research methods, deepening research on relevant mechanisms, and lifestyle interventions in view of the lack of previous research.

ABSTRACT

Major depressive disorder is a mental illness characterized by depressed mood, lack of engagement in pleasurable activities, anhedonia, and cognitive-behavioral disorders. Currently, traditional pharmacological treatments for depression have a delayed therapeutic onset and low treatment effectiveness. (2R, 6R)-HNK, as a key metabolite of ketamine, can not only exert rapid and lasting antidepressant effects but also has no side effects such as hallucination and addiction caused by ketamine, which has potential clinical application values. Studies have found that the antidepressant effect of (2R, 6R)-HNK is closely related to the regulation mechanism of glutamate receptor and synaptic plasticity. Besides, the changes of downstream signaling pathways include the upregulation of brain-derived neurotrophic factor (BDNF) expression, dephosphorylation of eukaryotic elongation factor 2 (eEF2), and activation of the mammalian target of rapamycin (mTOR) play a key role in the antidepressant process of the drug. Understanding the molecular mechanisms underpinning (2R, 6R)-HNK's antidepressant effects will be invaluable for the identification of targets, which will drive the development of novel, effective, next-generation pharmacotherapies for the treatment of depression.

ABSTRACT

Objective:To study and analyze the clinical effect of letrozole combined with metformin in the treatment of polycystic ovarian syndrome (PCOS)-associated infertility.Methods:From January 2019 to December 2019, 75 patients diagnosed with PCOS and insulin resistance index increased (>2.69)-associated infertility treated in Dalian Maternal and Child Health Care Hospital were selected. Patients were divided into control group (38 patients, treatment with letrozole) and experimental group (37 patients, treatment with letrozole combined with metformin) with a random number table method. Changes of fasting blood glucose (FBG) , fasting insulin (FINS) , insulin resistance level, ovulation rate, pregnancy rate, body mass and body mass index (BMI) were compared between the experimental group and the control group before and after treatment.Results:After treatment, the level of FBG in the experimental group was lower than that in the control group, but without significant difference ( P>0.05). The levels of FINS, insulin resistance index (HOMA-IR), the body mass and the BMI in the experimental group were significantly lower than those in the control group [ (13.66 ± 1.55) mU/L vs. (8.40 ± 2.31) mU/L, 3.10 ± 0.58 vs. 1.91 ± 0.63, (60.70 ± 4.61) kg vs. (65.99 ± 4.79) kg, (22.59 ± 1.64) kg/m 2 vs. (24.40 ± 1.70) kg/m 2], there were significant differences ( P<0.05). The ovulation rate and the pregnancy rate in the experimental group were significantly higher than those in the control group [91.9% (34/37) vs. 68.4% (26/38) , 45.9% (17/37) vs. 21.1% (8/38) ], there were significant differences ( P<0.05). Conclusions:The treatment of PCOS-associated infertility with letrozole combined with metformin could promote ovulation, and had positive effects in improving the pregnancy rate.

ABSTRACT

Objective:To compare the application effects of gonadotropin-releasing hormone agonist (GnRHa) and human chorionic gonadotropin (HCG) in the treatment of polycystic ovarian syndrome (PCOS)-associated infertility with clomiphene citrate (CC) combined with human menopausal gonadotropin (HMG).Methods:From June 2018 to June 2019, PCOS-associated infertile patients (80 patients) diagnosed in Dalian Maternal and Child Health Care Hospital were selected. Patients were randomly divided into GnRHa group (40 patients) and HCG group(40 patients) with a random number table method. All patients were performed with CC combined with HMG for ovulation induction. When the average diameter of the dominant follicle reached 18-20 mm, GnRHa 0.1 mg was used in the GnRHa group to induce follicle maturation, and HCG 10 000 U was used in HCG group to induce follicle maturation. Ovulation rate, pregnancy rate, early abortion rate, multiple pregnancy rate, ovarian hyperstimulation syndrome (OHSS) rate and luteinized unruptured follicle syndrome (LUFS) rate were compared between the two groups. The application effects of GnRHa and HCG in the treatment of PCOS-associated infertility with CC combined with HMG were analyzed.Results:There were no significant differences in the ovulation rate, the pregnancy rate, the early abortion rate, the multiple pregnancy rate and the LUFS rate between the GnRHa group and the HCG group ( P>0.05). The OHSS rate in the GnRHa group was significantly lower than that in the HCG group [0 vs. 15.0%(6/40)]( P<0.05). Conclusions:The incidence of OHSS is significantly lower in GnRHa induced follicular maturation compared with HCG induced follicular maturation in the treatment of PCOS-associated infertility with CC combined with HMG for ovulation induction.
