Objective To study the effects of cooking practice education on their status of nutrient intake and blood glucose control in patients with type 2 diabetes mellitus (T2DM) over 60 years old.Methods Four-hour cooking practice education lecture was offered per month for 57 patients with T2DM over 60-year old based on balance diet and food exchange list,with features including requiring patients joining the lecture with their family members together,demonstration of raw and fresh dietary materials and cooked food,choice of food to eat by the patients themselves according to their own dietary regimen.Sixty patients with T2DM who were only educated by outpatient department of nutrition for 35 minutes were selected as control.After twelve months of education,indices such as scores of awareness of knowledge of food exchange list,status of nutrient intake and blood glucose control,and so on,were compared between the two groups to evaluate the effects of cooking practice education.Results After 12- month education,score of knowledge of food exchange list in the experiment group increased significantly,as compared to that in the control group.Intake of energy [(6304?826) kJ] and fat [(46?6) g] decreased significantly in the experimental group [(6921?860) kJ and (63?9) g,respectively],and fasting blood glucose [(7.1?0.8) mmol/L],postprandial blood glucose [(11.2?1.1) mmol/L] and glycosylated hemoglobin A1c [(6.2?0.5)%] were decreased significantly,as compared to those in the control group [(7.8?0.9) mmol/L,(12.4?1.2) mmol/L,and (6.5?0.7)%)],respectively.Conclusions Cooking practice education is effective to correctly use diet regimen and improve status of nutrient intake and control of blood glucoses for over-60-year patients with T2DM.

OBJECTIVETo explore the effect of Changji'an Capsule (CA) on mRNA expressions of neuropeptide Y (NPY) in the hypothalamus and colon and serum levels of adreno-cortico-tropic hormone (ACTH) in rats of diarrhea predominant irritable bowel syndrome (IBS-D) model rats.

METHODSTotally 48 SD rats were randomly divided into six groups, i.e., the normal control group, the model group, the Pinaverium Bromide group (PB, 0.018 g/kg), the high dose CA group (2.812 g/kg), the medium dose CA group (1.406 g/kg), and the low dose CA group (0.703 g/kg), 8 in each group. The IBS-D rat model was established by using separation of breast milk + stimulation of acetic acid + constraint of four limbs. Normal saline was given to rats in the normal control group and the model group. All medication lasted for 14 successive days by gastrogavage. The serum content of ACTH was detected by enzyme linked immunosorbent assay (ELISA). The expressions of NPY mRNA in the colon and the hypothalamus were detected using real-time fluorescence quantitative PCR.

RESULTSCompared with the normal control group, the serum ACTH content significantly increased (P < 0.01), the NPY mRNA expression in the colon and the hypothalamus obviously decreased (P < 0.01) in the model control group. Compared with the model group, the serum ACTH obviously decreased in the high dose CA group, the medium dose CA group, and the PB group (P < 0.01, P < 0.05). The NPY mRNA expression in the colon and the hypothalamus were obviously up-regulated in the high dose CA group, the medium dose CA group, the low dose CA group, and the PB group (P < 0.05).

CONCLUSIONSCA could modulate the abnormity of brain-gut axis of IBS-D rats possibly by up-regulating NPY mRNA expressions in the hypothalamus and the colon and down-regulating the ACTH content in the hypothalamic-pituitary-adrenal axis.

OBJECTIVETo isolate the bioflocculant-producing bacteria from activated sludge and investigate the flocculating characteristics of the newly isolated bioflocculant.

METHODSBacteria were screened from activated sludge samples to isolate bioflocculant-producing bacteria. Flocculating activity was used as a measure of the flocculating capability of the bioflocculant.

RESULTSA novel bioflocculant-producing bacterium was isolated, which was identified to belong to genus Aeromonas and named as Aeromonas sp. N11. Flocculating activity increased in the presence of K+, Na+, or Ca2+. The highest flocculating activities for kaolin suspension were obtained in acidic pH ranges, and optimum pHs for it were 3.0, 4.0, and 5.0 with 1 mmol/L K+, Ca+, and Na+ present, respectively. The highest flocculating activities for soil suspension were observed at pH 8.0. The bioflocculant had a good flocculating activity and could achieve a flocculating activity of 92.4% for kaolin suspension at a dosage of only 1 mgxL(-1), and its activity in kaolin suspension was decreased by only 9.2% after heating at 100 degrees C for 60 min.

CONCLUSIONThe bioflocculant produced by Aeromonas sp. N11 has strong flocculating activity and high stability, which affords high possibility of its practical use.

OBJECTIVETo evaluate the safety of living related donors in short term after transplantation.

METHODSTwo hundred and fifty-one cases of living related donor kidney transplantation from May 2000 to July 2007 were analysed retrospectively. There were 117 male and 134 female aged from 22 to 72 years old, with a mean of 46.6 years old. The indexes were compared including serum creatinine (SCr), creatinine clearance (CCr), glomerular filtration rate (GFR) and quality of life before and after donation. Surgical complications were followed-up.

RESULTSDonors' SCr was (75.9 +/- 17.2) micromol/L before donation, (107.4 +/- 21.2) micromol/L on 7 d after donation, (130.4 +/- 58.2) micromol/L at the 1(st) month and (116.1 +/- 24.1) micromol/L at the 3(rd) month. There were significant difference between any 2 time points (P < 0.01). CCr was (94.4 +/- 17.5) ml/min before donation and (63.5 +/- 17.8) ml/min on 10 d after donation (P < 0.01). In 62 donors, total GFR was (82.4 +/- 21.8) ml/min before donation. On 10 d after donation, GFR of remaining kidney was (57.4 +/- 14.1) ml/min which was 34.7% higher than GFR of this kidney before donation (42.6 +/- 11.8) ml/min. There was no significant difference in quality of life before living related donors and non-donor populations (P = 0.116). Surgical complications included splenic rupture in 1 case, descending colon rupture in 1 case and wound infection in 5 cases.

CONCLUSIONLiving donor kidney transplantation is safe for donors, although part of indexes would vary within normal range during the early time after donation.

The genomic characteristics and cellular tropism of a Mangshi virus(MSV)isolated in China were investigated,thereby establishing a robust foundation for further research on the evolution and pathogenicity of MSV.The genome sequence of MSV strain V301/YNJH/2019 was obtained by next-generation sequencing,followed by phylogenetic tree construction and rearrangement assessment using software IQtree,RPD4,and Simplot.Viral proliferation was assessed in C6/36(Aedes albop-ictus),Vero(African green monkey kidney),and BHK(baby hamster kidney)cells.An initial epidemiological investigation of MSV in local cattle and goats was conducted using the serum neutralization test.The genome of MSV strain V301/YNJ H/2019 was 20623 bp in length,encompassing 12 segments of double-stranded RNA(Seg-1 to Seg-12).Sequence analysis confirmed genomic rearrangement of the Seg-1 and Seg-11 sequences,ex-hibiting high similarity to MSV isolated from lake sediment in China in 2022,while Seg-2 to Seg-10 and Seg-12 were most closely related to a MSV strain isolated from mosquitoes in China in 2013.The virus efficiently proliferated and induced sig-nificant cytopathic effects(CPE)in both C6/36 and BHK cells,but limited replication and no observable CPE in Vero cells.No detectable neutralizing antibodies against MSV were detected in 20 goat serum samples collected in Mangshi,while 2 of 20 bo-vine serum samples were positive with neutralizing antibody titers of 1:128 and 1:54.Whole genome sequencing revealed re-assortment events of the V301/YNJH/2019 strain,which is capable of infecting C6/36,BHK,and Vero cells.MSV infection was confirmed in cattle in Mangshi.

OBJECTIVE: To evaluate the effect of Kuntai capsule on the gonadotrophin releasing hormone agonist(GnRH-a)-induced perimenopaus symptoms and the sex hormone levels.METHODS: A total of 99 patients with uterine fibroids,adenomyosis or moderate to severe endometriosis who needed the treatment of GnRH-a at Sun Yat-sen Memorial Hospital of Sun Yat-sen University from June 2015 to March 2016 were collected and randomly divided into research group(Kuntai capsule)and control group(Tibolone). GnRH-a was injected once every 28 days and first injection of GnRH-a was administered on the 2 nd to 4 th day of menstrual period or retraction bleeding after surgery.Kuntai capsule or Tibolone was orally taken beginning from the first GnRH-a injection,and the co-administration of Caltrate D-600 and alfacalcidol was given in both groups.The Kupperman scores,sex hormone levels including folliclestimulating hormone(FSH)and estrogen(E_2),and adverse events were recorded.RESULTS: Kuntai capsule kept the perimenopause symptoms at mild level with the slow increase of Kupperman scores,whose effect was significantly superior to Tibolone(P<0.05)after 8 weeks of treatment,especially in paresthesia,nervousness,and formication.The FSH and E_2 levels in both Kuntai and Tibolone groups were obviously decreased when compared with the pre-treatment(P<0.05),and these hormone levels in Kuntai group were comparable to those in Tibolone group.No adverse events occurred in either group. CONCLUSION: In the short-term treatment of GnRH-a,Kuntai capsule exhibits significant alleviating effects on perimenopause symptoms caused by GnRH-a with high safety and few adverse reactions.

Objective To investigate the epidemiological characteristics and spatial distribution characteristics of Clonorchis sinensis human infections in Guangdong Province from 2016 to 2022, so as to provide insights into formulation of the clonorchiasis control measures in the province. Methods Xinhui District of Jiangmen City, Longmen County of Huizhou City and Wengyuan County of Shaoguan City in Guangdong Province were selected as fixed surveillance sites for human clonorchiasis from 2016 to 2022, and additional 10% to 15% counties (districts) endemic for clonorchiasis were sampled from Guangdong Province as mobile surveillance sites each year from 2016 to 2022. A village (community) was randomly selected from each surveillance site according to the geographical orientations of east, west, south, north and middle, and subjects were randomly sampled from each village (community). C. sinensis eggs were detected in subjects’ stool samples using the Kato-Katz technique, and the prevalence and intensity of C. sinensis infections were calculated. In addition, subjects’ gender, age, ethnicity, educational level and occupation were collected. The Guangdong Provincial 1:1 million electronic map in vector format was downloaded from the National Geomatics Center of China, and kernel density analysis and spatial autocorrelation analysis of C. sinensis human infections in Guangdong Province from 2016 to 2022 were performed using the software ArcGIS 10.7. Results A total of 153 188 residents were tested for C. sinensis infections in Guangdong Province from 2016 to 2022, including 75 596 men (49.35%) and 77 592 women (50.65%), and there were 5 369 residents infected with C. sinensis, with 3.50% overall prevalence of infections. The prevalence rates of severe, moderate and mild C. sinensis infections were 0.76%, 7.26% and 91.97% among C. sinensis-infected residents in Guangdong Province from 2016 to 2022, and there were age-, gender-, ethnicity-, occupation- and educational level-specific prevalence of C. sinensis human infections (χ² = 2 578.31, 637.33, 52.22, 2 893.28 and 1 139.33, all P values < 0.05). Global spatial autocorrelation analysis showed a cluster in the prevalence of C. sinensis human infections in Guangdong Province (Moran’s I = 0.63, Z = 27.31, P < 0.05). Kernel density analysis showed that the prevalence of C. sinensis human infections with a high kernel density in Guangdong Province was mainly distributed along the Zhujiang River basin in Pearl River Delta areas, followed by in eastern and northern Guangdong Province. In addition, local spatial autocorrelation analysis identified 73 high-high clusters of the prevalence of C. sinensis human infections in Guangdong Province. Conclusions The prevalence of C. sinensis human infections was high in Guangdong Province from 2016 to 2022, and mild infection was predominant among all clonorchiasis cases, with spatial clusters identified in the prevalence of C. sinensis human infections. Targeted clonorchiasis control measures are required among high-risk populations and areas.
