ABSTRACT

BACKGROUND@#As one of the most common endocrinal disorders for women at childbearing age, the diagnostic criteria of polycystic ovary syndrome (PCOS) have been defined differently among different international health organizations. Phenotypic heterogeneity of PCOS also brings about difficulties for its diagnosis and management assessment. Therefore, more efficient biomarkers representing the progression of PCOS are expected to be integrated into the monitoring of management process using metabolomic approaches.@*METHODS@#In this prospective randomized controlled trial, 117 PCOS patients were enrolled from December 2016 to September 2017. Classical diagnostic parameters, blood glucose, and metabolome were measured in these patients before and at 2 months and 3 months of different medical interventions. The receiver operating characteristic (ROC) curves were built based on multivariate statistical analysis using data at baseline and 3 months' management, and combinational biomarkers with appreciable sensitivity and specificity were selected, which then validated with data collected at 2 months.@*RESULTS@#A set of metabolites including glutamic acid, aspartic acid, 1-methylnicotinamide, acetylcarnitine, glycerophosphocholine, and oleamide were filtered out with high performance in representing the improvement through 3-month management of PCOS with high sensitivity and specificity in ROC analysis and validation with other two groups showed an appreciable area under the curve over 0.96.@*CONCLUSIONS@#The six metabolites were representative of the remission of PCOS through medical intervention, making them a set of potential biomarkers for assessing the outcome of PCOS management.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03264638.

ABSTRACT

Objective:To investigate the clinical efficacy of neoadjuvant chemo-hormonal therapy(NCHT)followed by radical prostatectomy(RP) plus extended pelvic lymphadenectomy for very-high-risk locally advanced prostate cancer.Methods:The data of 327 cases of very-high-risk locally advanced prostate cancer treated in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, The Second Hospital of Tianjin Medical University, and The Third Affiliated Hospital of Sun Yat-sen University from December 2014 to July 2019 were retrospectively analyzed. Patients were divided into two groups according to treatment regimens: the RP group (direct RP + extended pelvic lymphadenectomy 4-6 weeks after the biopsy of prostate) and the NCHT group (4-6 cycles of NCHT prior to RP). There were 171 cases in RP group and 156 cases in NCHT group, respectively. In the RP group, the median age was 67 (ranging 44-83)years. The median PSA at diagnosis was 27.24 (ranging 4.55-207.00) ng/ml. Patients’numbers of clinical T 2, T 3a, T 3b, T 4 stage were 13, 85, 57, 16, respectively, and clinical N 1, N 0 stage were 33 and 138, respectively. Patients’numbers of ISUP grade groups of 1, 2, 3, 4, 5 were 5, 35, 41, 51, 39, respectively. In the NCHT group, The median age was 67 years, ranging 46-78 years. The median PSA at diagnosis was 72.09(ranging 4.08-722.95)ng/ml. Patients’ numbers of clinical T 2, T 3a, T 3b, T 4 stage were 11, 47, 58, 40, respectively, and clinical N 1, N 0stage were 76 and 80, respectively. Patients’numbers of ISUP grade groups of 1, 2, 3, 4, 5 were 1, 11, 33, 43, 68, respectively. At baseline, the NCHT group showed higher PSA, higher ISUP grade, and more advanced clinical stage at diagnosis( P<0.05). The PSA, pathological down-staging rate, and positive surgical margin rate as well as the biochemical recurrence free survival(bRFS)were compared between the two groups. Results:After radical prostatectomy, compared with the RP group, the NCHT group had a higher proportion of patients achieving PSA<0.2 ng/ml at 6-week postoperative follow-up ( P<0.001), a higher pathologic tumor stage down-staging rate ( P<0.001), a higher ISUP down-grading rate ( P<0.001), and a lower positive surgical margins rate ( P<0.001). In addition, 10.9% of the NCHT group achieved pT 0 or minimal residual disease in postoperative pathology exams. Eighty-three patients (48.5%) in the RP group and 125 patients (80.1%) in the NCHT group achieved undetectable PSA after surgery and entered further analysis for bRFS, which showed NCHT group had significantly longer bRFS (19.46 months vs. 6.35 months). NCHT significantly reduced the risk for biochemical recurrence in locally advanced prostate cancer patients( HR=0.278, 95% CI 0.198-0.390, P<0.001). Such a reduce in risk for biochemical recurrence was seen in all subgroups( P<0.001). Conclusions:NCHT might improve surgical outcomes as well as bRFS in very-high-risk locally advanced prostate cancer patients.

ABSTRACT

Objective:To discover the clinical features of nocturnal enuresis (NE) in adults and to detect factors that correlated with the symptom severity.Methods:This cross-sectional study recruited NE subjects from September 2017 through December 2020. All patients had experienced enuresis at least once per week and with a symptom duration of 3 months or longer. Followed by documentation of history and medical records, three-day bladder diary was adopted to assess their voiding pattern, and urodynamic parameters were obtained to evaluate lower urinary tract function.Results:A total of 106 NE patients (43 male and 63 female) were identified. There is no statistical difference regarding the average age (men: 57.8±15.6 vs. women: 56.1±14.0, P>0.05) and BMI (men: 23.9±3.4 vs. women: 23.3±4.3, P>0.05) between men and women. Comorbidities are extremely common in NE patients (n=85, 80.2%), with the incidence rate higher in men compared to women [88.4% (38/43)vs. 74.6% (47/63), P<0.05]. Hypertension (n=58, 54.7%), hyperlipemia (n=41, 38.7%), diabetes mellitus (n=38, 35.8%), coronary heart disease (n=22, 20.8%) were the most frequently reported conditions. On bladder diaries, subjects were frequently manifested nocturnal polyuria (NP, 47/106, 44.3%), reduced nocturnal bladder capacity (NBC, 74/106, 69.8%), or combination of both(33/106, 31.3%). Urodynamic studies suggested that the incidence of reduce bladder compliance, detrusor overactivity (DO), stress incontinence, bladder outlet obstruction(BOO), detrusor underactivity(DU)and detrusor hyperreflexia with impaired contractility(DHIC)was 27.4%(29/106), 39.6%(42/106), 17.9%(19/106), 9.4%(10/106), 25.5%(27/106)and 15.1%(16/106), respectively. Women were more likely to suffer from stress urinary incontinence [2.3%(1/43) men vs. 28.6% (18/63) women, P<0.01], while men were prone to have bladder outlet obstruction [ 23.3%(10/43) men vs. 0 women, P<0.01]. Correlation analysis demonstrated that obesity( r=0.63, P<0.01), systemic comorbidities( r=0.40, P<0.01), presence of NP( r=0.50, P<0.01) and NP+ NBC( r=0.47, P<0.01), post-void residual( r=0.53, P<0.01), reduced compliance( r=0.21, P=0.04), DU( r=0.28, P<0.01), stress incontinence( r=0.42, P<0.01)and DHIC ( r=0.35, P<0.01)are positively correlated with NE severity. Whereas, reduced Q max( r=-0.35, P<0.01), low capacity( r=0.21, P=0.03), and reduced bladder sensation( r=-0.21, P=0.03) correlate negatively with NE severity. Conclusions:The presence of NE is not only a sign of bladder dysfunction, but also an implication of obesity, systematic chronic diseases, urine production malfunctioning. Therefore, a thorough history regarding the lower urinary tract function and systemic comorbidities should be taken carefully, so that, an integrated and personalized treatment can be carried out.

ABSTRACT

Objective@#The connectivity alterations in the putamen were found in revealing the neural correlates of attention-deficit/hyperactivity disorder (ADHD), but whether the effective connectivity of the putamen is atypical in ADHD remains unclear. Investigating this abnormality contributes to describing the neural circuit of ADHD at the level of macrostructural organization. @*Methods@#Data were acquired from thirty-two boys with ADHD and fifty-two matched typically developing controls (TDC) from Peking University (Peking) dataset deposited at the Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC) platform. We examined the effective connectivity of the putamen using Granger causality analysis (GCA) and then determined whether these connections could differentiate ADHD from TDC. @*Results@#Compared with TDC, the ADHD group showed decreased effective connectivity from the left ventral rostral putamen (VRP) to left calcarine (CAL), right medial part of the superior frontal gyrus, left orbital part of superior frontal gyrus and left middle occipital gyrus (MOG). Increased effective connectivity from the left inferior occipital gyrus and right lingual gyrus to left VRP was also found in ADHD. The result of the classification accuracy showed that 72.3% of participants were correctly classified using support vector machine. Moreover, GCA values from the left VRP to left CAL and left MOG were significantly correlated with hyper/impulsive scores of patients with ADHD. @*Conclusion@#The findings may help extend our understanding of the ADHD-related neural loops.

ABSTRACT

Objective@#The neuropeptide oxytocin has been found to improve human social cognition and promote prosocial behavior. However, itis still unclear about the mechanisms underlying these effects of oxytocin on neural processes, such as visual perception and awareness.Especially, it is still unclear whether oxytocin influences perceptual salience of social stimuli in the absence of awareness. @*Methods@#In a randomized double-blind, placebo-controlled trial we applied an interocular suppression paradigm and eye tracking @*methods@#to investigate the influence of intranasally administered oxytocin on perceptual salience of social stimuli. Suppression times andpupillometric data were measured during subjects being presented with gradually introduced pictures of social stimuli (neutral expressionfaces) or nonsocial stimuli (grayscale watch pictures) that were suppressed and invisible in 10 men who were administered 24 IU oxytocinand 10 men who were administered a placebo. @*Results@#The results demonstrated that the oxytocin group perceived social stimuli more quickly accompanied by subsequent larger increasingpupil diameter than nonsocial stimuli, indicating an increased unconscious salience of social stimuli. @*Conclusion@#These findings provided new insights into oxytocin’s modulatory role to social information processing, suggesting that oxytocinmight enhance attentional bias to social stimuli even after removal of awareness.

ABSTRACT

Prostate cancer is the second most common tumor in men worldwide, and high-risk and locally advanced prostate cancer are life threatening for patients. With the successful application of neoadjuvant therapy in more and more solid tumors, it’s application in prostate tumors has also been gradually started. Among these studies, neoadjuvant hormonal therapy and neoadjuvant hormonal therapy combined with chemotherapy are currently the most widely used. Although neoadjuvant hormonal therapy has been shown effective in reducing the positive rate of resection margins, it cannot improve the long-term survival of patients. Neoadjuvant hormonal therapy combined with chemotherapy may prolong the non-biochemical recurrence time of high-risk locally advanced patients, but whether patients can ultimately achieve survival benefits still needs to be further clarified in prospective randomized controlled studies.

ABSTRACT

Objective:To investigate the prognostic significance of tumor architecture in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy.Methods:A retrospective study was performed on 958 patients who underwent nephroureterectomy in Second Affiliated Hospital of Zhejiang university (156) and Renji Hospital (802) between January 1998 and June 2019. There were 630 males and 328 females with median age 67 years old, ranging 30-89 years old. Among them, 499 patients suffered with preoperative hydronephrosis, 370 patients suffered with hypertension, 120 patients suffered with diabetes, 252 patients had history of smoking and 119 patients had history of non-muscle invasive bladder cancer (NMIBC) or with NMIBC. 489 patients had tumor in renal pelvic, 394 patients had tumor in ureter and 75 patients had tumor in both sites. Laparoscopic surgery was performed in 543 patients while open surgery was performed in 415 patients. The χ 2 test was used to detect the association between tumor architecture and several clinicopathological features. Kaplan-Meier method with the log-rank test was used to assess survival analysis. Multivariate analyses were conducted using Cox proportional-hazards regression model. Results:516 cases (53.9%) showed papillary architecture(Group A) and 442 cases (46.1%) showed sessile architecture(Group B). 543 patients had a tumor ≤3 cm and 415 had a tumor >3 cm. Low pathological grade and high grade was diagnosed in 275 and 683 patients, respectively. The distribution of pathological stage was pT a-1 in 441 cases, pT 2 in 180 cases, pT 3 in 308 cases and pT 4 in 29 cases. Lymphadenectomy was performed in 227 patients and 62 patients were pathologically confirmed lymph node metastasis. 48 patients were found squamous or glandular differentiation. Lymphovascular invasion (LVI) was observed in 150 patients. 134 patients were multifocality. Positive surgical margin was found in 43 patients. Median follow-up was 39 (ranging, 2-206) months. During follow-up, a total of 304 patients died and 236 died of UTUC. 5-year OS and CSS were 76.6% and 81.8%, respectively, in patients with papillary architecture (group A), which were significantly higher than 54.4% and 60.5% in patients with sessile architecture (group B, all P<0.001). Patients in group B had more female patients (38.9% vs.30.3%, P=0.005), ureteral location (47.1% vs. 36.1, P=0.002), hydronephrosis (55.9% vs.48.8%, P=0.030) and postoperative adjuvant chemotherapy (27.1% vs. 14.7%, P<0.001), higher pathological grade (89.6% vs.55.6%, P<0.001) and stage (79.4% vs.32.4%, P<0.001), lymph node metastasis rate (12.0% vs.1.7%, P<0.001), squamous or glandular differentiation (9.5% vs.1.2%, P<0.001) and LVI (24.4% vs.8.1%, P<0.001) than patients in group A. Cox multivariate regression analysis showed that sessile architecture ( P=0.022, 0.028), age ≥65 years ( P<0.001, <0.001), history of diabetes ( P=0.008, 0.043), history of NMIBC or with NMIBC ( P<0.001, <0.001), higher grade ( P=0.002, <0.001), advanced tumor stage ( P=0.003, 0.005), lymph node metastasis ( P=0.003, 0.044), squamous or glandular differentiation ( P=0.008, 0.027) and positive surgical margin ( P=0.003, 0.010) were independent risk factors for OS and CSS. However, tumor >3 cm ( P=0.013, 0.131) and positive LVI ( P=0.045, 0.174) were independent risk factors for CSS rather than OS. Conclusions:UTUC is high malignancy. Tumor architecture was one of an independent risk factor for OS and CSS in UTUC patients and sessile tumors were more malignant, more aggressive and have worse prognosis.

ABSTRACT

Objective:To study the pathological characteristics, diagnosis and treatment of primary adenocarcinoma of renal pelvis and ureter.Methods:The clinical pathological characteristics, treatment and prognosis of 5 patients with adenocarcinoma of upper urinary tract treated between January 2007 and May 2019 was retrospectively reviewed. There were 4 male and 1 female patients, with a median age of 60 years. The major symptoms were hematuria in 5 cases and low back pain in 4 cases. All cases underwent B-ultrasound and CT examination, and 4 cases accepted cystoscopy. Preoperative diagnoses were ureter tumor in 2 cases, renal pelvis tumor in 1 case, renal tumor in 1 case and renal calculus in 1 case.Results:5 cases were treated with surgery. Radical nephroureterectomy was performed in 3 cases, and nephrectomy in one case. 1 case underwent first-stage percutaneous nephrolithotomy and second-stage radical nephroureterectomy due to the discovery of tumor. 1 case was treated with radiotherapy and immune checkpoint inhibitor postoperatively. The mean diameter of the tumors was 4.4 cm. There were 3 renal pelvis adenocarcinomas and 2 ureter adenocarcinomas confirmed by pathologic examination, including 3 cases of pT 3 stage and 1 case of pT 4 stage. Lymph node metastasis was found in 2 cases. Immunohistochemistry revealed that CDX2(+ ), p63(-), GATA3(-), β-catenin(-)were the common features of five cases. The median survival was 12 months with a median follow-up of 6 months. 2 cases died of tumor progression within 1 year. Conclusions:Adenocarcinoma is an extremely rare malignancy, typically associated with long-standing calculi and chronic inflammation. Given the fact that clinical and imaging findings are nonspecific, the diagnosis is based on pathologic examination, supported by glandular structure of histology. Immunohistochemical staining exhibited CDX2 and CK20 positivity and β-catenin negativity, moreover, GATA3, p63 and CK7 was usually negative or partially positive. Surgery is the foremost choice of treatment. The prognosis is correlated with subtypes, whereas the overall prognosis is poor due to high rates of recurrence and metastasis.

ABSTRACT

Objective:To investigate the diagnosis, treatment and prognosis of squamous cell carcinoma of renal pelvis.Methods:The clinic data of 28 cases with squamous cell carcinoma of renal pelvis confirmed by pathologic examination treated during June 2007 and September 2019 was retrospectively analyzed. There were 19 male and 9 female patients, with a median age of 56 years. Hematuria was present in 18 cases, flank pain was present in 11 cases, and abdominal mass was present in 1 case. All 28 cases accepted CT or MRI examination. Renal pelvis or renal tumors were found in 26 cases, and severe hydronephrosis was observed in 2 cases. 2 cases underwent PET/CT, and bone metastasis was found in 1 case. Preoperative diagnoses were renal pelvic tumor in 13 cases, renal tumor in 13 cases and renal abscess in 2 cases. Coexisting renal calculi or renal pelvic calculus was detected in 19 cases. All 28 cases underwent surgical excision, including radical nephroureterectomy in 13 cases, radical nephrectomy in 12 cases, palliative resection in 1 case, and pyonephrenectomy in 2 cases. Enlarged lymph nodes were found in 9 cases during the surgery, and local lymph node dissection was performed in these cases.Results:The mean diameter of the tumors was 8.5 cm. Histopathological examination revealed that 9 cases were well differentiated, 11 cases were moderately differentiated, and 8 case was poorly differentiated. 1 case had pT 2 stage, 15 cases had pT 3 stage and 12 cases had pT 4 stage. 9 cases had lymph node metastasis. 5 cases had renal vein thrombosis. Immunohistochemistry staining exhibited consistent characteristics including CK5(+ ), 34βE12(+ ), p63(+ ), CK20(-) and GATA3(-). Postoperatively, 12 cases received adjuvant therapy including chemotherapy, radiotherapy and/or immunotherapy. Within a median follow-up of 6.0 months (ranging 1-80 months), median overall survival was 10.0 months. 15 cases died of tumor progression. Conclusion:Squamous cell carcinoma is a rare and highly aggressive neoplasm, typically associated with long-lasting renal calculi, hydronephrosis and chronic inflammation. The diagnosis should be established on pathologic examination.CK5, 34βE12 and p63 positivity contribute to the diagnosis of squamous cell carcinoma. Surgery is the foremost choice of treatment, but the risk of recurrence and metastasis is high. The prognosis is extremely poor as the majority of patients are diagnosed with advanced stages.

ABSTRACT

OBJECTIVE@#To evaluate the effects of Chinese medicine Dingkun Pill () alone or in combination with Diane-35 on patients with polycystic ovary syndrome (PCOS).@*METHODS@#This is a prospective randomized controlled trial conducted at Peking Union Medical College Hospital Beijing, China, from December 2016 to September 2017. Totally 117 PCOS patients were randomly assigned to the Dingkun Pill group (38 cases), Diane-35 group (40 cases), or combined group (39 cases). Patients in the Dingkun Pill group or Diane-35 group took daily 7 g of oral Dingkun Pill or 1 tablet of oral Diane-35, respectively, for 21 consecutive days followed by 7 drug-free days. And the combined group received a combination of Dingkun Pill and Diane-35. The treatment course was 3 months. Fasting plasma glucose and insulin, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), free fatty acids (FFA) and sex hormones were analyzed, quantitative insulin sensitivity check index (QUICKI) was calculated, and menstruation and acne scores were recorded at baseline and after 3-month treatment.@*RESULTS@#Compared with before treatment, QUICKI decreased significantly in the Dingkun Pill and combined groups after 3-month treatment (P0.05).@*CONCLUSIONS@#Dingkun Pill showed better effects than Diane-35 in improving insulin sensitivity, lowering TC and FFA. Diane-35 was more efficient in regulating menstruation and lowering androgen than Dingkun Pill. Combination of Dingkun Pill and Diane-35 may be a better choice to regulate menstruation, lower androgens while improve glucose metabolism in PCOS patients.

ABSTRACT

To obtain ultrasound and thermal tomography images of breast cancer during its growth and to assess the value of thermal tomography in detecting breast cancer. Breast cancer models were established with NOD/SCID mice and SD rats. These animal models were examined by thermal tomography,plain ultrasound,and contrast-enhanced ultrasound. Tumor tissues were stained with CD34 to explore the relationship between tumor heat production and vascular pathology. Thermal tomography detected breast cancer 2-4 days earlier than ultrasound. The expression of CD34 in tumor tissues was increased,along with thickened,increased,and irregular blood vessels. Thermal tomography can detect early breast cancer and is a promising tool for screening breast cancer.

ABSTRACT

@#Objective: To observe whether an Xingnaojing 醒脑静 injection could improve the prognosis of patients, by increasing rifampicin penetration through the blood-brain barrier. Methods: Patients with severe tuberculous meningitis were enrolled in this study. The concentrations of Xingnaojing in cerebrospinal fluid and blood in patients treated with Xingnaojing and control were determined by high performance liquid chromatography. The changes in cerebrospinal fluid and the improvement of clinical symptoms and signs, were evaluated two weeks after admission. The long-term prognosis of the patients in the two groups were evaluated by the Glasgow Outcome Scale (GOS). Results: The concentration of rifampicin in cerebrospinal fluid was significantly higher in the Xingnaojing group (1.77±0.17 μg/mL), than in the control group (1.27±0.16 μg/mL, p<0.05). The difference in concentration of rifampicin in the blood was not significant (P>0.05). The short-term effective rate of the Xingnaojing group was 92.5% (37/40), which was significantly higher than that of the control group (80%, 32/40, p<0.05). After 6 months, 75% (30/40) of the Xingnaojing group had good prognosis according to the GOS score, whereas that of the control group was 50% (20/40) showing significantly better long-term treatment effect of the Xingnaojing group compared to the control group (P<0.05). Conclusion: Xingnaojing injection improved rifampicin penetration into the central nervous system. The increase in rifampicin concentration in cerebrospinal fluid improved outcomes in patients with severe tuberculous meningitis.

ABSTRACT

Cellular oncosis is an important non-apoptosis mode of cell death characterized by cell swelling and karyolysis. Studies have indicated that cellular oncosis is involved in the progress of tumor and cardiovascular diseases as well as other diseases. The selection of appropriate detection method is the key to the study of cellular oncosis. However, there is still no unified standard of detection methods for cellular oncosis. Therefore, this paper summarizes the concept and characteristics of cellular oncosis, as well as principle, the advantages and disadvantages of existing detection methods, so as to provide reference for the selection of detection methods and promote the research on cellular oncosis.

ABSTRACT

OBJECTIVE:To pro vide suggestions for imp roving the quality of ethical review of drug clinical trials in China and protecting the rights and interests of subjects. METHODS :Guided by risk management theory ,the literature research method , expert opinion method and analytic hierarchy process method were used to sort out the ethical review process of drug clinical trials , extract and determine the risk factors that affect the quality of ethical review ,and determine the weight of each risk factor. Suggestions were put forward improving the ethical review of drug clinical trials in China. RESULTS & CONCLUSIONS : Established ethical review risk index system of drug clinical trials included 31 influential factors of 5 aspects;the order of importance(weights)of 5 aspects affecting the quality of ethical review of drug clinical trials was as follows :the construction of the medical ethics committee (0.263 5),the management of review meetings (0.251 4),follow-up review (0.194 5),the acceptance and processing of review applications (0.189 2),and the management of documents and files (0.101 4). The influential factors with high weight included “withdrawal of people with conflict of interest in the discussion and voting process (0.078 7)” “timely review or conference discussion of scheme modification ,informed consent modification ,serious adverse events ,etc. (0.070 5)”“clarification and external exhibition of the work process and time of ethical review (0.059 8)”“unified and standardized review standards and approval standards (0.052 1)”,etc. The quality of ethical review can be improved by avoiding people with conflict of interest in the discussion and voting process ,timely reviewing or holding ethics meetings on scheme modification , informed consent modification ,serious adverse events ,etc.,clarifying the working process and time of ethical review ,and establishing unified and standardized review standards and approval standards.

ABSTRACT

OBJECTIVE@#To assess the efficacy and safety of the Chinese medicine Dingkun Pill (, DKP) on insulin resistance in women with polycystic ovary syndrome (PCOS).@*METHODS@#A total of 117 women with PCOS were randomly assigned to Group A (38 women), Group B (40 women), or Group C (39 women) in a randomization sequence with SAS software and a 1:1:1 allocation ratio using random block sizes of 6, and were given 7 g of oral DKP daily (Group A), 1 tablet of Diane-35 orally daily (Group B), or 7 g of oral DKP daily plus 1 tablet of Diane-35 orally daily (Group C). Patients took all drugs cyclically for 21 consecutive days, followed by 7 drug-free days. The treatment course for the 3 groups was continued for 3 consecutive months. Oral glucose tolerance tests (OGTT) were performed before treatment and again after 2 and 3 months of therapy, respectively, and homeostasis model assessment for insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (QUICKI) were calculated.@*RESULTS@#Of 117 women with PCOS, 110 completed the entire course of therapy: 35 in Group A, 36 in Group B, and 39 in Group C. After treatment, all three groups showed significant decreases in fasting glucose: at 1 h glucose decreased significantly in Group A (by 0.5 ± 1.4 mmol/L, P=0.028) and Group C (by 0.5 ± 1.2 mmol/L, P=0.045); while showing a tendency to increase in Group B (by 0.4 ± 1.9 mmol/L, P=0.238). HOMA-IR decreased significantly in Group C [by 0.5 (-2.2 to 0.5) mIU mmol/L, P=0.034]. QUICKI was significantly increased in Groups A and C (by 0.009 ± 0.02, P=0.033 and by 0.009 ± 0.027, P=0.049, respectively), while no change was observed in Group B. Repeated-measure ANOVA showed that the absolute changes in all parameters (except for glucose at 1 h), including glucose and insulin levels at all time-points during OGTT and in HbA1c, HOMA-IR, and QUICKI, were not significantly different among the 3 groups after treatment (P>0.05).@*CONCLUSION@#DKP or DKP combined with Diane-35 produce a slight improvement in insulin sensitivity compared with Diane-35 alone in PCOS patients (Trial Registration: ClinicalTrials.gov, NCT03264638).
