ABSTRACT
Objective To investigate the accuracy of body mass index (BMI) as the evaluation standard for obesity in Miao adults in Guangxi, to find out the BMI cutoff value suitable for the evaluation standard of adult obesity, and to provide an accurate and reliable reference value for the prevention and treatment of obesity in Miao nationality adults. Methods Using a cross-sectional design, residents aged 18 years or older in the Miao villages in Rongshui Miao Autonomous County, Guangxi, were selected as the research subjects, and their body composition was measured. The percent body fat (PBF) standard was used as the “gold standard” for obesity, and the BMI standard for obesity in Chinese adults was used as the positive screening standard. The accuracy of the BMI standard was evaluated, and the ROC curve analysis was used to determine the optimal BMI cutoff value for obesity in Miao adults. Results The detection rate of obesity of Miao adults in Guangxi by BMI method was lower than that by PBF method (10.3% vs 19.0%, χ2=426.62, P“gold standard”, BMI had a good diagnostic performance for obesity in Miao adults (AUC=0.959, P2 and 25.55 kg/m2 for men and women, respectively. Conclusion BMI is of great value for the diagnosis of obesity in Miao adults, but it should not be used as an exclusion criterion for obesity. Especially in the case of a small sample size, the risk of misclassification bias is relatively high.
ABSTRACT
Objective To analyze the composing principles of the prescriptions for Lijie disease by using The Prescription of Traditional Chinese Medicine Dictionary. Methods The prescriptions for Lijie disease in the book of The Prescription of Traditional Chinese Medicine Dictionary were collected. Database was established by using TCM Inheritance Support System (V1.1). Medicine using frequency, composing principles, and composition of new medicine were analyzed through association rules and entropy clustering method. Results Based on the analysis on 187 cases of prescriptions, 42 Chinese herbal medicines were with the frequency of 42 times and Angelicae Sinensis Radix was the core herbal medicine. 69 core combinations with three to four herbal medicines and 6 new prescriptions were obtained through evolution. Conclusion According to the analysis of composing principles and clustering new prescriptions of Lijie disease, the treatment for Lijie disease is toning liver and spleen, and nourishing liver and kidney.
ABSTRACT
Objective To study the differences in body composition and blood lipids between the pre-and post-menopausal women of Maonan ethnicity , and to explore the correlations between body fat content , fat distribution and blood lipids.Methods Totally 200 Maonan pre-and post-menopausal women were randomly selected from Huanjiang county in Guangxi.Body composition were measured by bioelectrical impedance analysis (BIA), and blood lipids were tested from blood samples .Results Compared with the pre-menopausal women , the visceral fat level (/area ) , waist-hip ratio (WHR), left (/right) lower limbs fat, total cholesterol (TC), triglyceride (TG) and low-density lipoprotein( LDL-C) in post-menopausal women were significantly higher ( P <0.01 ) , and the detection rate of hypercholesterolemia , mixed hyperlipidemia and dyslipidemia in postmenopausal group was also significantly higher ( P<0.01 ) .All the blood lipids were closely related to WHR and visceral fat content (P<0.05 or P<0.01).In addition, TG, high-density lipoprotein ( HDL-C) and LDL-C except TC were significantly correlated to %BF, BMI and subcutaneous fat content ( P<0.05 or P<0.01).Conclusion The accumulation of visceral and abdominal fat in Maonan postmenopausal women is significantly correlated to dyslipidemia .The results may provide references for making preventive program for the Maonan women .
ABSTRACT
Objective To investigate the distribution of six short tandem repeats(STR) loci in Maonan in Guangxi province and to study genetic relationship among 6 minorities.Methods Two hundreds unrealated individulas were analyed by STR genescanning.Genetic distance was computed and phylogenetic tree was construted for studying genetic relationship among 6 Ethnic groups.Results The average heterozygosity(H) in the six STR loci was 0.7825;the average polymorphism information content(PIC) was 0.7324;the accumulative discrimination power(DP) was 0.99999951,and the accumulative probability of paternity exclusion(EP) was 0.994575.All 6 populations were clustered into 2 group.Conclusion Allele 16 in D3S1358,allele 11 in D5S818,allele 11 in D7S820,8 in D13S317,14 in vWA,22 in FGA are probably the most primitive alleles in repective locus.The data obtained indicate highly genetic polymorphisms.Genetic relation between Maonan and Mulao were close.
ABSTRACT
0.05).Conclusion The 15 STR loci of Miao ethnic group show the characteristics of high polymorphism and hereditary stability.Therefore,the obtained data can be of applicable value in human population of Guangxi Miao genetics investigation,and forensic application,as well as individual identification and parent checkup.
ABSTRACT
Objective The aim of this study was to analyze the causes of misdiagnosing xanthogranulomatous cholecystitis (XGC) as carcinoma of gallbladder.Methods Clinical data of 33 XGC patients admitted from 1996 to 2005 were retrospectively analyzed, among them 10 patients were misdiagnosed as carcinoma of the gallbladder preoperatively and intraoperatively. Results All these 10 patients underwent preoperative ultrasound and computed tomography (CT). Both ultrasound and CT were suggestive of carcinoma of the gallbladder in 5 cases, and chronic cholecystitis in one case. The ultrasound was suggestive of carcinoma while CT diagnosed as chronic cholecystitis in 2 cases. CT suggested a carcinoma while ultrasound was suggestive of cholecystitis in other 2 cases. Thickened gallbladder wall and dense carcinoma-like adhesions was unanimous phenomena. Cholecystectomy and partial hepatic wedge resection was performed in 3 cases; Six cases underwent cholecystectomy and partial hepatic wedge resection plus regional lymphadenectomy. One case received partial cholecystectomy, cholecystoenterostomy, and partial transverse colectomy. XGC was definitely diagnosed by postoperative pathological examination in all of patients. Conclusions XGC mimics the imaging features (CT, ultrasonography) and gross findings of gallbladder carcinoma making a misdiagnosis. Definite diagnosis of XGC is dependent on postoperative pathology.
