ABSTRACT
Objective@#To analyze the epidemiological and etiological characteristics of hand-foot-mouth disease (HFMD) in Tongren City during 2018 to 2022, so as to provide the reference for HFMD effective prevention and control.@*Methods@#Monitoring data on HFMD in Tongren City from 2018 to 2022 was collected from National Infectious Disease Reporting Information Management System. Descriptive epidemiological method was conducted on the data analysis.@*Results@#A total of 14 376 cases of HFMD were reported in Tongren City during 2018 to 2022, the average annual incidence rate of HFMD was 89.43/100 000. Totally 47 severe cases were reported, accounting for 0.33% of the total cases. The incidence rates of HFMD were generally declining trend during 2018 to 2022 (124.68/100 000, 95.37/100 000, 78.50/100 000, 61.63/100 000, 87.80/100 000) ( χ 2 trend =393.05, P <0.01), mainly occurred during April to July (48.13%), among children under 5 years old (95.72%). During 2018 to 2022, a total of 967 laboratory diagnosed cases reported in different years, regions, age groups showed significant differences in pathogen composition ratio ( χ 2=169.62, 456.65 , 167.96, P <0.05). From 2018 to 2022, the dominant pathogen of HFMD was constantly changing. Other enteroviruses were the dominant epidemic strains in 2018 and 2022 (33.04%, 37.62%), CoxA 6 was the dominant epidemic strain in 2019 to 2020 ( 68.75 %, 50.78%), and CoxA16 was the dominant epidemic strain in 2021(43.30%).In 2018, one case was infected with CoxA16 and EV71.The difference of pathogen composition ratio varied in different years ( χ 2=169.62, P <0.01).@*Conclusions@#The prevalence of HFMD in Tongren City has showed a declining trend during 2018 to 2022, and the dominant strain of HFMD has changed in recent years. The pathogen monitoring of HFMD should be strengthened to timely grasp the distribution and changes of pathogens, so as to provide a basis for the precise prevention and control of HFMD.
ABSTRACT
Objective To investigate the effect of Huangkui extract powder (HK) on the expression of nephrin and podocin proteins in mouse podocytes induced by high glucose,which is involved in the treatment of diabetic nephropathy (DN).Methods Cultured mouse podocytes (MPC5) were incubated in high glucose and HK at 5.6 mmol/L NG,5.6 mmol/L NG + 0.45 g/L HK,25 mmol/L HG,25 mmol/L HG + 0.45 g/L HK,respectively.The 5.6 mmol/L NG group was used as normal control.After 24 hours of intervention,we detected podocyte apoptosis by Annexin-V FITC/PI double staining,measured the mRNA and protein expression of nephrin and podocin by qRT-PCR and Western blot.Results Compared with the control group (5.6 mmol/L,NG),the apoptosis rate of podocytes in the high glucose concentration group (25 mmol/L,HG) was significantly higher [(20.39 ± 0.03) ％ vs.(17.70 ± 0.91) ％,t =2.947,P ＜ 0.05)].The apoptosis rate of podocytes in the 25 mmol/L HG + 0.45 g/L HK group was significantly lower than that in the 25 mmol/L HG group [(11.96 ± 1.11) ％ vs.(20.39 ± 0.03) ％,t =7.586,P ＜ 0.01].The results of qRT-PCR and Western blot showed that the expression of nephrin and podocin was significantly inhibited by high glucose concentration compared with the control group[(0.489 ±0.040) vs.(0.721 ±0.022),t =4.992,P ＜0.01;(0.387 ±0.014) vs.(0.778 ±0.036),t =10.050,P ＜0.01],and the expression of podocin and nephrin was increased by appropriate concentration of H K [(0.603 ± 0.013) vs.(0.489 ± 0.040),t =2.653,P＜0.05;(0.640±0.024) vs.(0.387 ±0.014),t=8.946,P＜0.01].Conclusion Podocyte apoptosis can be induced by prolonged high glucose treatment,but a certain concentration of HK can inhibit podocyte death induced by high glucose.The possible mechanism is that HK may inhibit the apoptosis of podocytes by regulating the expression of podocin and nephrin in podocytes at high glucose concentration,thus plays a protective role on podocytes.
ABSTRACT
Objective:To observe the impact of rehabilitation training,acupuncture-moxibustion combined with Danshen Chuanxiongqin acupoint injection on the patients with shoulder-hand syndrome (SHS) after cerebral infarction (CI).Methods:82 patients with SHS after CI from March 2014 to March 2016 in our hospital were randomly divided into the group A and the group B (n=41).Patients in the group A received comprehensive drug therapy,acupuncture and rehabilitation training,the group B was given Danshen Chuanxiongqin acupoint injection therapy based on the group A.Before and after treatment,the upper limb movement function score (FMA),digital pain score (NRS),the degree of swelling in the shoulder joint,shoulder joint of motion (ROM),and neural function defect scale (CNFDS),daily life activities ability (MBI) and quality of life scores (WHOQOL) of patients in two groups were compared and analyzed.Results:After treatment,the scores of NRS,shoulder swelling,upper extremity CNFDS were significantly higher than those before treatment,the ROM,while the upper extremity FMA,MBI and WHOQOL of both groups were significantly decreased (P＜0.05),these index improved more significantly in group A than those of group B (P＜0.05).Conclusion:Rehabilitation training,acupuncture-moxibustion combined with Danshen Chuanxiongqin acupoint injection was more effective in the treatment of SHS after cerebral infarction than rehabilitation training and acupuncture-moxibustion.
ABSTRACT
Background:Fanconi anemia( FA ),an autosomal or x-linked recessive inherited disease,is caused by gene mutation related to FA pathway of DNA damage and with the clinical features of congenital malformation,bone marrow failure and susceptibility to cancer. Aims:To investigate the expression of Fanconi anemia complementation group D2 (FANCD2)in colorectal cancer and its correlation with prognosis. Methods:Fifty-six surgical resected specimens of colorectal cancer tissue and para-cancer noncancerous tissue from May 2012 to September 2013 at Guangzhou First People’s Hospital were obtained. Ninety-three patients with colorectal cancer from January 2008 to April 2009 at Guangzhou First People ’s Hospital were enrolled and the specimens of colorectal cancer tissue were obtained. The expression of FANCD2 mRNA in 56 specimens of colorectal cancer tissue and para-cancer noncancerous tissue was determined by qPCR. The expression of FANCD2 protein in 49 of 56 specimens of colorectal cancer tissue and para-cancer noncancerous tissue and 93 specimens of colorectal cancer tissue was determined by immunohistochemistry. Follow up was conducted in 93 patients and the correlation between the expression of FANCD2 and prognosis was analyzed. Results:Expression of FANCD2 mRNA was significantly higher in colorectal cancer tissue than that in para-cancer noncancerous tissue [0.102(0.047,0. 163)vs. 0. 051(0. 025,0. 095)](P =0. 007). Expression of FANCD2 mRNA was significantly correlated with lymph node metastasis and Dukes stage( P <0. 05 ). Positivity rates of FANCD2 protein expression in colorectal cancer tissue and para-cancer noncancerous tissue were 77. 6%(38/49)and 22. 4%(11/49),respectively. Expression of FANCD2 protein was significantly correlated with lymph node metastasis and Dukes stage(P<0. 05). The overall 5-year survival rate was significantly lower in patients with positive expression of FANCD2 protein than that in patients with negative expression of FANCD2 protein(35. 5% vs. 71. 0%)(P<0. 01). Conclusions:FANCD2 is associated with malignant potential of colorectal cancer and could be a potential marker for prognosis.
