ABSTRACT
Objective:To investigate the image characteristics of woven coronary artery (WCA)on intravascular ultrasound(IVUS) and optical coherence tomography(OCT).Methods:Thirty-seven patients suspected of WCA on coronary angiography were enrolled from Teaching Hospital of Chengdu University of Traditional Chinese Medcine, Zhengzhou Cardiovascular Disease Hospital and Zhongshan Hospital of Fudan University from January 2013 to July 2020. The intraluminal imaging features of WCA were analyzed using IVUS and OCT.Results:Of the 37 patients admitted at the cardiology service, 9 patients had WCA. All the patients underwent coronary angiography, IVUS and OCT, of which 6 lesions were located on the right coronary artery, 2 lesions were located on the left anterior descending artery and 1 patient had WCA on the circumflex artery. The mean length of WCA lesions was 2.2 cm(ranged from 1.2 cm to 4.5 cm). The angiographic appearance of WCA was numerous small tortious channels origined form the main lumen. The channels appeared to be " doughnut" like pattern and they merged to normal artery again after the anomalous segment. Flow limitation was rare unless there was coronary atherosclerosis. OCT and IVUS showed multiple spiral channels in the anomalous segment, which were independent of each other and each channels had a relatively complete three-layers vascular structure.Conclusions:With typical image characteristics, IVUS and OCT are able to screen out WCA and guide the treatment decision making.
ABSTRACT
Background@#Most antipsychotic drugs studies have been mainly conducted on side effects, randomized clinical trials, utilization rates, and trends. But there have been few studies on the influencing factors in elderly patients. The purpose of this study was to analyze the influencing factors on the outpatient prescription of antipsychotic drugs in the elderly patients. @*Methods@#Active ingredients of antipsychotic drugs in Korea were selected according to the Korean Pharmaceutical Information Center (KPIC)’s classification. Data source was Korean Health Insurance Review and Assessment Service (HIRA) claims data in 2020 and target patient group was the elderly patient group. We extracted patients who have been prescribed one or more antipsychotic drugs and visited only one medical institution. Data were analyzed using descriptive statistics, chi-square, t-test, negative binomial regression. @*Results@#A number of outpatients were 245,197 and prescriptions were 1,379,092. Most characteristics of patients were 75-85 year’s old, female, health insurance type, no disease (dementia, schizophrenia), atypical drugs, cci score (>2) and characteristics of medical institution were neurology in specialty, rural region, general hospitals. Results of regression showed that patient’s characteristics and medical center characteristics had significant effect on the outpatient prescription of antipsychotic drugs in the elderly patients. @*Conclusion@#This study suggests that national policy of antipsychotic drugs in the elderly patients, with the consideration of the patients’ and medical institutions’ characteristics, is needed.
ABSTRACT
A cordycipitoid fungus infecting Hepialidae sp. in Nepal was supposed to be identical to Cordyceps liangshanensis, originally described from southwestern China, and thus, transferred to the genus Metacordyceps or Papiliomyces in previous studies. However, our multi-gene (nrSSU-nrLSU-tef-1α-rpb1-rpb2) phylogenetic and morphological studies based on the type specimen and additional collections of C. liangshanensis revealed that the fungus belongs to the genus Ophiocordyceps (Ophiocordycipitaceae). Therefore, a new combination O. liangshanensis was made, and a detailed description of this species was provided.
ABSTRACT
Objective: To investigate the frequency characteristics and the pathological characteristics of the horizontal crista ampullaris in patients with Meniere's disease,and to analyse its structural basis. Methods: Between March, 2019 and November, 2019, seventy-two patients diagnosed as Meniere's disease (27 males and 45 females, aged from 13 to 74 years, with a course of disease ranging from 4 months to 32 years)in Shandong Provincial ENT Hospital were included.Caloric test, sinusoidal harmonic acceleration test (SHA), video-head impulse test (v-HIT), Gadolinium-enhanced inner-ear 3D-FLAIR MRI and pure tone audiometry were conducted in the patients. The function of the horizontal semicircular canal in these patients were analysed as well as its relationship with the degree of endolymphatic hydrops,clinical stage and duration. Light microscopy and transmission electron microscopy were used to observe the ultrastructure of horizontal semicircular canal crista ampullaris from six patients with refractory Meniere's disease who underwent labyrinthectomy. The number of type Ⅰ and type Ⅱ vestibular hair cells, the common pathophysiological changes of horizontal semicircular canal crista ampullaris were investigated in these patients. Statistical analysis was performed using SPSS 19.0. Results: With the increase of detection frequency, the abnormal rate decreased gradually. The abnormal rate of caloric test was 69.4% (50/72), SHA 51.4% (37/72), V-HIT 36.1% (26/72), comparation of the positive rate among the three tests showed statistically significant differences(P<0.05).Neither caloric test nor SHA had correlation with the degree of hydrops(P>0.05), but v-HIT(r=0.434,P<0.01).There was correlation with clinical stage to SHA and v-HIT(r=0.338,0.462,P<0.01), except caloric test(P>0.05).No significant relation was found with caloric test, SHA, v-HIT and course of disease(P>0.05).Morphological observation found abnormal monolayer epithelialization of the horizontal semicircular canal crista ampullaris significantly decreased number of type Ⅱ hair cells compared with type Ⅰhair cells. Hair cells showed perinuclear vacuolization, cytoplasmic vacuoles, mitochondrial electron density increasement and loss of stereocilia. Conclusions: The horizontal semicircular canal damage in the patients with Meniere's disease has a frequency-dependent characteristic, mainly occurres in low frequency area. With progress of the disease, the high frequency area of ampulla will be impaired gradually, and it is related to the degree of endolymphatic hydrops and hearing level. Hair cell injury would be observed,the frequency characteristics may be more associated with the disorder of type Ⅱ hair cells.

ABSTRACT
【Objective】 To explore the application of capillary ultracentrifugation technology in accurate identification of Rh phenotype and clinical blood transfusion. 【Methods】 132 samples, presenting mixed field agglutination during Rh phenotyping in our laboratory from May 2019 to February 2020, were separated using capillary ultracentrifugation technology, and the proximal and distal red blood cells were taken for Rh phenotype test, and then blood donors with the same Rh phenotype as the proximal cells were selected for cross matching. 【Results】 132 samples were subjected to capillary ultracentrifugation, and new red blood cells were successfully isolated from the proximal side in 128 (96.97%)cases, and the Rh phenotype was accurately identified, i.e. CcDEe in 47 cases (36.72%), CcDee in 12(9.38%). ), ccDEEin 11 (8.59%), CCDee in 52(40.63%), ccDEe in 5 (3.91%), and ccDee in 1(0.78%). 4 cases of mixed field reaction remained after centrifugation, and all of them had a history of blood transfusion within 2 days. For the 128 patients whose Rh phenotype was accurately identified, blood donors with the same type of Rh phenotype were selected, and 4 patients whose Rh phenotype could not be determined, donors with CCDee phenotype were selected based on the frequency of phenotype distribution and the principle of reducing antigen exposure. The cross-matched blood of all patients were consistent. 【Conclusion】 Capillary ultracentrifugation technology can effectively separate the new red blood cells, improve the accurate identification of Rh phenotype, and provide safety guarantee for clinical targeted blood transfusion.
ABSTRACT
Objective To explore the clinical significance of detecting CD4+ T cell ATP and subgroup count in patients with liver cancer recurrence after liver transplantation. Methods From November 2015 to November 2018, 84 patients with primary liver cancer underwent orthotopic liver transplantation in Shanghai Changzheng Hospital were selected and then divided into recurrence group (n=42) and non-recurrence group (n=42) according to whether the tumor recurred. Peripheral blood samples were collected on the day of diagnosis and 1, 3, 6 months after recurrence. ATP content in CD4+ T lymphocytes was detected using ImmuKnowTM immune cell function assay kit, subgroup counts were detected using IOTest. Results ATP content of CD4+ T lymphocytes in patients with liver cancer recurrence after liver transplantation was significantly lower than that in patients without recurrence at the day of diagnosis of recurrence, and 1, 3, 6 months after recurrence (P<0.05). The count of CD4+ T lymphocyte subsets in the reoccurence group had no significant change within 1 month after recurrence compared with the non-recurrence group. When the recurrence time continued to extend to 3 months and 6 months, there was a significant downward trend in both the two groups. Conclusion The immune status of patients with liver cancer recurrence after liver transplantation decreased gradually with the passage of time. Monitoring the ATP content and subgroup count of CD4+ T cells can better evaluate the immune status of patients with liver cancer recurrence after liver transplantation, being of certain practical value in formulating individualized programs.
ABSTRACT
Objective To evaluate clinical factors associated with laboratory-confirmed influenza infection and probe into the effects of different influenza-like illness(ILI) definitions on influenza surveillance in hospitalized children. Methods The influenza surveillance on the hospitalized children with acute respiratory infection was carried out in Soochow university affiliated children’s hospital from October 2017 to May 2018. The definition of influenza-like illness(ILI), which proposed by world health organization (WHO), the European center for disease prevention and control (ECDC) and ministry of public health of China, was analyzed to determine the area under receiver operating characteristic curve (ROC), sensibility, specificity, and the positive and negative predictive values of the ILI definition using the laboratory evidence of influenza virus infection as golden criteria. Logistic regression model was employed to explore the risk factors of the laboratory confirmed influenza infection among the hospitalized children. Results Of the enrolled 1 459 hospitalized children, 204(14.0%) were lab-confirmed influenza cases. The ECDC definition had the highest sensitivity (91.7%, 95% CI: 87.9%-95.5%) but the lowest specificity (44.6%, 95% CI: 41.9%-47.4%). The WHO definition had the lowest specificity (70.6%, 95% CI: 64.3%-76.8%). China’s definition was the most discriminant definition with relatively high sensitivity (91.2%, 95% CI: 87.3%-95.1%) and specificity (51.5%, 95% CI: 48.8%-54.3%), and its positive area under curve value (71.2%, 95% CI: 67.9%-74.5%) was the highest. Multivariate analysis model showed that the detection rate of influenza virus in children with fever (≥38 ℃) was higher than that in children without fever (OR=7.03, 95% CI:3.89-12.70). Conclusions It is suggested to adopt China’s ILI definition to get better output during influenza surveillance among hospitalized children.
ABSTRACT
This study aims to investigate the effect of down-regulation of miR-205-5p by transfection of miR-205-5p inhibitor on the sensitivity of HNE1/DDP cells to cisplatin (DDP) induced apoptosis and explore the underlying mechanism. qRT-PCR was used to detect the expression of miR-205-5p in HNE1 or HNE1/DDP cells. The expression level of miR-205-5p was analyzed after transfecting HNE1/DDP cells with miR-205-5p inhibitor. MTT assay was used to evaluate the inhibitory effect of DDP alone or in combination with miR-205-5p inhibitor on the proliferation of HNE1/DDP or HNE1 cells. Apoptosis of cells treated with miR-205-5p inhibitor alone or in combination with DDP (8 μmol·L-1) was assessed using flow cytometry with PI staining, with the nucleus was counterstained with DAPI staining. The expression of Bax, Bak, Mcl-1, or Bcl-2 was analyzed by Western blot. HNE1/DDP cells showed a high level of expression of miR-205-5p, and the expression of miR-205-5p was significantly decreased by transfection of miR-205-5p inhibitor. Down-regulation of miR-205-5p significantly increased the sensitivity of HNE1/DDP cells to DDP (P<0.05). Transfection of miR-205-5p inhibitor enhanced the sensitivity of HNE1/DDP cells to DDP induced apoptosis. Treatment of HNE1/DDP cells with miR-205-5p inhibitor combined with DDP (8 μmol·L-1) for 24 h resulted in an apoptotic rate of 28.93% ± 2.50%, significantly higher than that treated with miR-205-5p inhibitor (9.83% ± 1.31%) or DDP alone (10.83% ± 1.70%) (P<0.05). DAPI staining showed that HNE1/DDP cell nucleus became significantly condensed and fragmented in miR-205-5p inhibitor combined with DDP group. The combined group up-regulated the expression of Bax and down-regulated the expression of Bcl-2 in HNE1/DDP cells. Therefore, down-regulation of miR-205-5p can enhance the sensitivity of HNE1/DDP cells to cisplatin induced apoptosis, and the mechanism may involve up-regulation of Bax and down-regulation of Bcl-2 expression.

Background@#Extranodal natural killer/T-cell lymphoma (ENKTL), nasal type, is an aggressive entity within the World Health Organization classification of lymphoid tumors. The International Prognostic Index is reported to be prognostically meaningful for ENKTL, but lacks discriminatory power for stage I/II ENKTL with extensive local invasion. This study aimed to evaluate the prognostic effects of local invasion by site and tissue type in patients with ENKTL.@*Methods@#We retrospectively analyzed data of 86 patients who were diagnosed with ENKTL by the Department of Pathology of Beijing Tongren Hospital from June 2002 to April 2016, and ascertained tumor infiltration of adjacent structures (AS), bone, and soft tissue for each patient, using physical findings and imaging scans. We used univariate and multivariate analysis to assess the association of each involved tissue or site with patients’ overall survival (OS).@*Results@#Of the 86 patients, 71(82.6%) experienced invasion of AS, 22(25.6%) of soft tissue, and 26(30.2%) had bone involvement. Overall, patients with AS involvement did not show significantly shorter survival than those without AS involvement (Log rank χ2 = 1.177, P = 0.278); however, patients who had involved eyeballs or brains showed significantly lower 2-year OS rates than those without eyeball involvement (Log rank χ2 = 4.105, P = 0.043) or brain involvement (Log rank χ2 = 7.126, P = 0.008). Patients with involved local soft tissue or bones, respectively, showed lower 2-year OS rates than those without involved local soft tissue (Log rank χ2 = 10.390, P = 0.001) or bones (Log rank χ2 = 8.993, P = 0.003). Multivariate analysis showed that involvement of the cheek or facial muscles (hazard ratio, HR = 5.471, 95% confidence interval [CI]: 1.466–20.416, P = 0.011) and the maxilla bone (HR = 6.120, 95% CI: 1.517–24.694, P = 0.011) were significantly independent predictors of lower 2-year OS rates.@*Conclusions@#Imaging can accurately detect ENKTL invasion of AS, soft tissue, and bone. Involvement of local soft tissue or bone was significantly associated with lower 2-year OS rates. Involvements of the cheek or facial muscle, as well as maxilla bone, are independent predictors of lower 2-year OS rates in ENKTL patients.

ABSTRACT
OBJECTIVE@#To investigate the viral etiology and allergen distribution in infants and young children at high risk of asthma during a wheezing episode.@*METHODS@#A total of 135 infants and young children at high risk of asthma were enrolled who were admitted due to asthmatic bronchitis or asthmatic bronchopneumonia between April 2016 and August 2017. Fluorescent probe PCR was used to measure influenza A (Flu A), respiratory syncytium virus (RSV), adenovirus (ADV), parainfluenza virus (PinF), human rhinovirus (HRV), human partial lung virus (hMPV) and human bocavirus (HBoV) in nasopharyngeal aspirates. ImmunoCAP was used to measure inhaled allergens, food allergens, and total IgE concentration.@*RESULTS@#Among the 135 patients, the overall virus detection rate of nasopharyngeal aspirates was 49.6%, and HRV had the highest detection rate of 25.2%, followed by HBoV (9.6%), RSV (8.1%), PinF (5.9%), Flu-A (3.7%), ADV (1.5%) and hMPV (0.7%). The 1-3 years group had a significantly higher detection rate of HRV than the <1 year group (P<0.05). The positive rate of allergen screening was 59.3%, with 44% for inhaled allergens and 89% for food allergens. Among the inhaled allergens, dust mites had the highest positive rate of 77%, followed by mould (37%), pollen (26%) and animal dander (9%). Among the food allergens, egg white had a positive rate of 73% and milk had a positive rate of 68%. The <1 year group had a significantly higher positive rate of inhaled allergens than the 1-3 years group (P<0.05). The 1-3 years age group had a significantly higher level of T-IgE than the <1 year group (P<0.05). The positive virus group had a significantly higher positive rate of inhaled allergens than the non-virus group (P<0.05). The children with the second wheezing episode had significantly higher positive rates of inhaled allergens and food allergens and level of T-IgE than those with the first wheezing episode (P<0.05). The children with the second wheezing episode also had significantly higher positive rates of dust mites and mould than those with the first wheezing episode (P<0.05).@*CONCLUSIONS@#Early HRV infection and inhaled allergen sensitization are closely associated with the development of wheezing in infants and young children at high risk of asthma.

ABSTRACT
Objective To analyze the changes in lung function and inflammatory indicators such as eosino-phils(EOS),Creola bodies and exhaled nitric oxide(FeNO),and to explore their value in early diagnosing asthma. Methods One hundred and thirty-five infants with high-risk asthma were selected as an observation group who were admitted to Department of Respiratory,Childrenˊs Hospital of Soochow University from April 2016 to August 2017 due to asthmatic bronchitis and asthmatic bronchopneumonia,and a total of 200 non -asthmatic and non -allergic healthy children who were screened and followed up at the Department of Cardiology in the same period were selected as a healthy control group for the measurement of moist respiratory lung function and FeNO. In the observation group,the bronchial dilation test(BDT),EOS and Creola bodies were performed simultaneously. Classification of lung function:23%≤time to peak ratio(TPTEF/Te)<28% had mild obstruction,15%≤TPTEF/Te<23% had moderate obstruc-tion,and TPTEF/Te<15% showed severe obstruction. Results The TPTEF/Te[17. 20%(8. 10%)],volume to peak ratio(VPEF/Ve)[21. 20%(6. 20%)],tidal volume per kilogram of body weight(VT/kg)[7. 80(3. 70)]and ratio of tidal expiratory flow 25% to peak tidal expiratory flow(25/PF)[0. 54(0. 20)]in the observation group were signifi-cantly lower than those in the healthy control group[22. 30%(9. 22%),27. 15%(7. 10%),8. 90(3. 17),0. 60 (0. 18)],and the differences were statistically significant(Z＝ -6. 81,-9. 35,-3. 16,-3. 52,all P<0. 05). BDT positive rate in the mild obstruction group was 20. 00%(3/15 cases),BDT positive rate in the moderate obstruction group was 26. 56%(17/64 cases),and BDT positive rate in the severe obstruction group was 48. 72%(19/39 cases). The higher the degree of obstruction,the higher the value of BDT positive diagnosis(F＝6. 353,P<0. 05). BDT of VPEF/Ve,25/PF and TPTEF/Te were consistent and statistically significant(Kappa＝0. 78,0. 49,all P<0. 001). Ti-dal expiratory flow 50% -remaining(TEF50% -r)[(117. 86 ± 42. 16)mL/s],tidal expiratory flow 25% -remai- ning(TEF25% -r)[(82. 82 ± 35. 44)mL/s]in the second wheezing group were higher than those in the first whee-zing group[(92. 81 ± 28. 40)mL/s,(65. 22 ± 24. 93)mL/s],and the differences were statistically significant( t＝3. 34,2. 77,all P <0. 05). There was no statistically significant difference in sputum EOS,FeNO and Creola body scores among wheezing children between the first and second groups(all P>0. 05). FeNO in the observation group [3. 80(5. 43)μg/L]was significantly lower than that in the healthy control group[9. 60(11. 3)μg/L],and the diffe-rence was statistically significant(Z＝14. 56,P<0. 05). Sputum EOS had a positive correlation with blood EOS and Creola bodies(r＝0. 20,0. 21,all P<0. 05);there was no correlation between lung function parameters and inflamma-tory indices(all P>0. 05). Conclusions In the acute phase of infant asthma attack,the pulmonary function presents different degrees of obstructive ventilation dysfunction,the higher the degree of obstruction,the higher the diagnostic value of BDT. The value of single FeNO measurement is limited,and continuous dynamic monitoring may be more mea-ningful in predicting the occurrence of asthma.

@#Pai syndrome is a rare syndrome of unknown cause, comprising a particular variety of congenital developmental malformation with variable phenotypical presentations. It was first reported by Pai et al., in 1987 when it was described in a male new-born as an unusual combination of three rare anomalies, i.e., complete median cleft lip, cutaneous polyps, and developmental midline lipomas of the central nervous system. 1 After that, over sixty similar cases have been reported, although their phenotypic presentations were not very similar, ranging from mild-facial dysmorphism to severe frontonasal dysplasia (FND). The perceived impression about the underlying aetiology goes towards a multifactorial origin. No chromosomal abnormalities have been described in patients with PS on karyotype. Diagnosis of the syndrome is based on clinical signs and associated pathology, the common clinical component being midline facial skin masses. Minimum diagnostic criteria as suggested by Castori et al. 2 and Lederer et al. 3 , one or more hamartomatous nasal polyps plus median cleft lip (with or without cleft alveolus), and/or alveolar process congenital polyp, and/or pericallosal lipoma. Pericallosal lipoma is a common finding (85%) in this syndrome which is frequently associated with various degrees of intracerebral malformations such as agenesis or dysgenesis of corpus callosum. 3 Most of the cases of PS have been diagnosed postnatally after birth. Typically, the condition is still not found to have any negative impact on psychoneurological development. In a recent report of an 8-year-long follow-up case, Imai et al., observed some attention-deficit disorder, but its definite relationship with the syndrome is yet to be confirmed. 4
ABSTRACT
<p><b>OBJECTIVE</b>To explore the safety and effectiveness of percutaneous transforaminal endoscopic BEIS technology for lumbar lateral recess stenosis in the elderly.</p><p><b>METHODS</b>From February 2014 to May 2016, 21 patients with lumbar lateral recess stenosis in elderly were treated with percutaneous endoscopic BEIS. There were 13 males and 8 females, aged from 70 to 85 years old with an average of 74.3 years. Preoperative, 1 and 12 months postoperative visual analogue scale(VAS) scores and Oswestry Disability Index(ODI) were statistically analyzed. MacNab was used to assess the clinical effects.</p><p><b>RESULTS</b>All the operations were successful. The time ranged from 90 to 130 min with an average of 110 min. All the patients were followed up for 12 to 38 months with an average of 18 months. Preoperative, 1 and 12 months postoperative VAS scores were 8.47±1.23, 1.78±0.72, 0.68±0.32, and ODI scores were 32.48±10.03, 19.53±3.55, and 5.15±1.02, respectively. Postoperative scores of VAS and ODI were obviously improved(<0.05). According to modified MacNab standard to evaluate the clinical effects, 14 cases obtained excellent results, 5 good, 2 fair. Lower limb paresthesia occurred in 1 case, and the condition was restored at 3 months postoperatively with conservative treatment. One patient was complicated with emphysema before operation secondary to pulmonary infection, and was effectively controlled with regulate antibiotic therapy. No infection of vertebral body or intervertebral space, no injuries of blood vessels or nerve root, no tear of dura, or the leakage of cerebrospinal fluid were found.</p><p><b>CONCLUSIONS</b>Percutaneous transforaminal endoscopic BEIS is a safe and effective method for lumbar lateral recess stenosis in the elderly.</p>

The macroporous microspheres were prepared through suspension polymerization and based on a copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate.The effect of porogen on the microspheres structure was evaluated in terms of pore size and surface area.Porogen contained dichloromethane (δ=9.7 (cal/cm3)1/2) and N-octanol (δ=10.3 (cal/cm3)1/2) which corresponded to a good and poor solvent,respectively.The solubility parameter of porogen was controlled in the range of 9.89-10.09 (cal/cm3)1/2.The pore size of microspheres increased with the difference value of solubility parameter between the polymer and the porogen.On the contrary,the surface area of microspheres decreased in this study.The anion exchange media was prepared through coupling poly(ethylene imine) in the microspheres,and the proteins transport was determined by frontal analysis method.The macroporous microspheres with 257 nm pore size could still afford a high proteins capacity (45.1 mg/mL).These macroporous supports showed a large potential in a rapid separation of proteins.
ABSTRACT
<p><b>Background</b>Obesity induces dyslipidemia, hypertension, glucose intolerance, and inflammatory state, which results in atherogenic processes, diabetes, and cardiovascular disease. We usually use body composition indices, such as body mass index (BMI), body fat percentage (BFP), waist circumference-height ratio (WHtR), and waist-hip ratio (WHR) to reflect the obesity. The aim of this large population-based cross-sectional study was to investigate the associations between body composition indices and metabolic parameters in Chinese adults.</p><p><b>Methods</b>A total of 12,018 Chinese adults were included. Body composition indices, such as BMI, BFP, WHtR, and WHR, and metabolic parameters, such as systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglyceride (TG), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), fasting blood glucose (FBG), 2 h postprandial blood glucose (2h PBG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), insulin resistance index (HOMA-IR), high-sensitivity C-reactive protein (hs-CRP), and white blood cell count (WBC), were measured and analyzed. All analyses were stratified by gender.</p><p><b>Results</b>All body composition indices and metabolic parameters except 2h PBG differed significantly between males and females (all P < 0.001). BMI was positively associated with SBP, DBP, LDL-C, TC, TG, FBG, 2h PBG, HbA1c, FINS, HOMA-IR, hs-CRP, and WBC, and inversely associated with HDL-C; similar relationships were identified between the metabolic parameters and BFP, WHtR, and WHR. In the multivariate analysis, the odds of impaired glucose regulation, dyslipidemia, insulin resistance, and increased hs-CRP were 1.36, 1.92, 3.44, and 1.27 times greater in the overweight group than those in the normal weight group, respectively, and 1.66, 3.26, 7.53, and 1.70 times greater in the obese group than those in the normal weight group, respectively. The odds of dyslipidemia and hs-CRP were 1.29 and 1.38 times greater in the BFP ≥28.0% group than in the BFP <28.0% group, respectively. The odds of dyslipidemia, HOMA-IR, and hs-CRP were 1.55, 1.26, and 1.48 times greater in the WHtR ≥0.96 group than in the WHtR <0.96 group, respectively. Among males, the odds of HOMA-IR were 1.46 times greater in the WHR ≥0.54 group than in the WHR <0.54 group. Similar results were observed in females.</p><p><b>Conclusions</b>This study identified positive associations between all evaluated body composition indices and metabolic parameters in Chinese adults. Among the body composition indices, BMI predicted four of the five evaluated metabolic disorders in both gender groups.</p>
