AIM: The auxology-related indexes are important for tissue construction. In this article, we investigated the incidence of overweight and obesity and their effects on physical functions and qualities of Guangzhou adults in 2005. METHODS: 2 056 adults including 1 027 males and 1 029 females were randomly selected from Guangzhou in 2005 for physical examination. The anthropometric data such as body mass and height were collected to calculate body mass index (BMI). The subjects were divided according to the BMI criteria recommend by Group of China Obesity Task Force, and their physical functions and qualities were analyzed. RESULTS: In 2005, the detection rate of overweight and obesity in adult males were 28.7% and 5.2%, and in females were 18.6% and 5.3%. The values of diastole pressure and systolic pressure were increased with BMI, but the change tendency of step index and vital capacity/body mass was decreased with BMI. The rate of hypertension was increased with BMI, and male subjects had higher rate of hypertension than that of female subjects in all groups. Obese adult had the poorest values in vertical jump and sit-and-reach test. Those people with normal BMI had better balance ability than that of overweight and obese people. CONCLUSION: The rates of overweight and obesity in Guangzhou adult show a high level. The physical functions and qualities may be improved when the body mass increases or decreases in a certain range, but obesity has impact to those values.

Aim To investigate the drug-containing serum of Rhizoma drynariae on osteogenesis differentiation of bone marrow mesenchymal stem, and discuss the possible mechanism.Methods BMSCs were cultured in media with different concentrations of medicine containing serum.BMSCs proliferation ability was detected in 3,5,7,9 days by CCK-8.ALP activity was detected after 7,10,14 days′ induction.After 3 weeks culturing, alizarin red staining was performed to observe the formation of calcium nodules.The expression of β-catenin,LRP5,RUNX-2 and Osteriex mRNA were detected using RT-PCR.The protein expression of β-catenin,LRP5 was detected using Elisa method.Results Rhizoma drynariae drug-containing serum could obviously promote the proliferation of BMSCs and calci-fied nodule formation.Besides, the ALP activity was improved in a certain period of time.The expression of β-catenin,LRP5,GSK-3β,RUNX-2 and Osteriex mRNA were significantly up-regulated,and the protein expression of β-catenin,LRP5 was up-regulated too.The expression of GSK-3β was down-trgulated.Conclusions Rhizoma drynariae drug-containing serum promotes mineralization and osteogenic differentiationof BMSCs, and the mechanism is closely related with activating WNT/beta-catenin signaling pathway, raising the beta-catenin, LRP5, RUNX-2, and Osteriex mRNA expression, beta-catenin, LRP5 protein expression,and down-regulation of GSK-3β mRNA expression.

Objective　To compare the changes in the genetic diversity of Anopheles minimus through the research on the population genetic characteristics of Anopheles minimus between different years in Nabang Town, Yingjiang County, Yunnan Province. Methods Anopheles mosquitoes were collected by light traps in Nabang Town, Yingjiang County, Yunnan Province in May 2014 and May 2021. After morphological identification, each mosquito was individually stored in separate tubes for further analysis. DNA of Anopheles minimus was extracted using kits. Microsatellite sequences in the template DNA were amplified using eight pairs of fluorescent primers, and the resulting products were subjected to capillary electrophoresis by a sequencing company. PopGen32 software was used to calculate the observed number of alleles (Na), effective number of alleles (Ne), observed heterozygosity (Ho), expected heterozygosity (He), and Shannon's information index (I) for individual microsatellite loci and population groups. PIC-CALC software was used to calculate the polymorphic information content (PIC). Results A total of 158 mosquitoes belonging to 6 Anopheles species were captured in 2014, while 529 mosquitoes belonging to 5 Anopheles species were captured in 2021. The composition ratio of Anopheles minimus among the mosquito species differed significantly between 2014 and 2021 (χ2=70.48, P<0.01). For 8 microsatellite loci, a total of 85 alleles were detected, a range of 6-20 alleles per locus and an average of 10.625 alleles. Ne ranged from 1.717 to 7.797, with an average of 4.011. The highest PIC was found in the am4 locus, and the lowest in the am25 locus. For the population groups, 77 alleles were found in 2014, and 62 alleles were found in 2021. Ne ranged from 1.630 to 8.658, with an average of 4.147 in 2014. Ne ranged from 1.760 to 6.744, with an average of 3.698 in 2021. The average Ho was 0.641 in 2014 and 0.650 in 2021, while the average He was 0.699 in 2014 and 0.691 in 2021. The Shannon's index ranged from 0.774 to 2.493 in 2014, with an average of 1.579, and from 0.938 to 2.224 in 2021, with an average of 1.464. Na, Ne, I, and PIC were all higher in 2014 compared to 2021, with Na: 9.625>7.750, Ne: 4.147>3.698, I: 1.579>1.464, and PIC: 0.655>0.640, respectively. Conclusions The populations of Anopheles minimus in Nabang Town, Yingjiang County, exhibited high levels of polymorphism in both 2014 and 2021. However, the genetic diversity of the population in 2021 was lower than that in 2014.

Objective To observe the clinical effect of Xiaoke-Yuzu decoction on diabetic peripheral neuropathy (DPN). Methods A total of 100 DPN inpatients were recruited and randomly divided into the treatment and control groups. The two groups were both received basic therapy, while the treatment group additionally received Xiaoke-Yuzu decoction. Toronto clinical scores and Chinese medicine symptom scores of both groups were collected to evaluate the clinical effect before and after the therapy.

Meanwhile, the Chinese medicine symptom scores of treatment group were also significantly lower than the control group (main symptom score 1.77 ± 1.17 vs. 3.17 ± 1.82, posterior symptom score 2.23 ± 1.59 vs. 4.27 ± 1.57, the tongue and pulse score 1.83 ± 0.65 vs. 2.47 ± 0.51, all P<0.05). Conclusion Xiaoke-Yuzu decoction plus basic therpy could improve the clinical symptoms of DPN patients.

Purpose To investigate the clinical characteristics and Oxford classification of IgA nephropathy patients with hyperurice-mia. Methods 151 IgA nephropathy patients confirmed by renal biopsy in 2013 were analyzed retrospectively. The patients were di-vided into the two groups:IgA nephropathy patients with or without hyperuricemia. Morphological changes were evaluated with Oxford classification scoring system and Lee’s grades. A comparative analysis of clinical manifestations and pathological injuries was performed between the two groups. Results Incidence of hyperuricemia in IgA nephropathy patients was 48. 3% and was more common in young men. Hypertension was associated with hyperuricemia. Oxford classification of IgA nephropathy patients with hyperuricemia was pre-dominant M1E0S1T0 and Lee’s grades presented with grade Ⅲ. The outstanding histopathologic features with higher plasma uric acid levels indicated higher tubulointerstitial chronicity, higher glomerular sclerosis ratio, accompanied by a decline in glomerular filtration rate. There was no significant difference of vascular lesions. Conclusions The prevalence of hyperuricemia in IgA nephropathy pa-tients is high. Oxford classification shows IgA nephropathy with hyperuricemia are associated with more severe tubulointerstitial lesions and lower GFR.

Background:Gankyrin is an ankyrin repeat oncoprotein overexpressed and involved in the tumorigenesis and progression of various cancers. Aims:To investigate the effect and underlying mechanism of down-regulation of gankyrin expression on proliferation of gastric cancer cells. Methods:Lentivirus vector carrying gankyrin-targeted siRNA was transfected into human gastric cancer cell line MKN28. Cell proliferation,cell cycle distribution and β-catenin/ cyclin D1 signaling pathway was analyzed by MTT assay,flow cytometry and Western blotting,respectively,in gankyrin-silenced MKN28 cells and control cells. Results:The transfection efficiency of lentivirus vector was more than 90% ,and the protein expression of gankyrin in gankyrin siRNA transfected MKN28 cells was significantly repressed( P ﹤ 0. 01). Compared with cells transfected with control lentivirus and cells without transfection,MKN28 cells transfected with gankyrin siRNA showed markedly repressed cell growth after 3-day-culture;the proportion of cells in cell cycle G1 phase was significantly increased,and that in S phase was significantly decreased;down-regulated expression of β-catenin and cyclin D1 was observed(P all ﹤ 0. 01). Conclusions:Down-regulation of gankyrin expression in gastric cancer cells may induce cell cycle G1 phase arrest and inhibit cell proliferation by suppressing β-catenin/ cyclin D1 signaling pathway. Gankyrin might be a promising novel target for targeted therapy of gastric cancer.

Objective:To study the effect of changing operator on the detection rate of colorectal polyps during surgery in patients who had been diagnosed with colorectal polyps by electronic colonoscopy for the first time.Methods:From June 2016 to June 2019, the patients who had been diagnosed with colorectal polyps by electronic colonoscopy for the first time, they were performed by electronic colonoscopy for the second time after 3 months by 5 doctors in the No.946 Hospital of PLA who had engaged in endoscopic work longer and been with rich experience. The results of the electronic colonoscopy were recorded and compared.Results:Fived hundred and seventy-six patients were found have colorectal polyps through electronic colonoscopy for the first time. Among them, 423 patients came to the hospital within 3 months and were eligibled for the research. The detection rate of newly detected polyps by the same operator was 22.7%(96/423), after changing the operator, the detection rate became 24.3% (103/423), but there was no significant difference ( P>0.05). The detection rates of newly detected polyps were respectively 20.8% (220/1 059) and 25.9%(294/1 133), the proportion of newly detected polyps with diameter ≤ 5 mm was respectively 73.6%(162/220) and 82.0%(241/294), the ratio of flat polyps to total newly detected polyps was 71.8%(158/220) and 79.9%(235/294), and there were significant differences ( P<0.05). The proportion of polyps in sigmoid colon was respectively 35.0% (77/220) and 39.1%(115/294), and there was no significant difference ( P>0.05). Conclusions:For patients with colorectal polyps detected by electronic colonoscopy, the operator should be changed during surgery, so that more missed polyps can be detected during surgery, especially flat polyps with diameter ≤ 5 mm. The operator should be changed to improve the detection rate and reduce the probability of missed diagnosis.
