Objective To investigate the current status of infection management quality control centers in county-level hospitals in Guangdong Province,providing reference for the development of quality control management programs for county-level infection control centers by provincial infection control centers,and exploring corresponding management strategies.Methods A survey was conducted using the QuestionStar questionnaire platform to investigate county-level quality control centers established in Guangdong Province before December 31,2023.The survey covered the establishment time,personnel structure,level of in-formatization,management,quality control,and training of hospital infection management professional quality control centers.Results There are 68 county-level infection control centers in Guangdong Province,with a coverage rate of 50.37%,and 95.59%of them have been established within the past five years.Experts mainly come from clinical and nursing backgrounds(accounting for23.75%and62.97%respectively),and the majority have a bachelor's degree(71.06%).Only 13%have operational funding.Among them,39 have established hospital infection informatization monitoring,23 have not been equipped,and 6 are under construction.Twenty centers have conducted quality control supervision and issued quality control reports,ac-counting for 29.41%,while 41 have organized training,accounting for 60.29%.Conclusion The coverage rate of county-level infection management quality control centers in Guangdong Province is steadily increasing,but not all counties and districts are covered.There is a lack of policy and funding support,insufficient personnel allocation,and inadequate professional coverage.The health administrative departments and county-level infection control centers need to unify monitoring standards,quality con-trol specifications,and evaluation programs,improve infection control capabilities,and enhance the"four-level"management and training system to effectively promote the quality and safety management level of primary healthcare institutions.

There is increasing evidence that the activation of glucagon-like peptide-1 receptor(GLP-1R)can be used as a therapeutic intervention for cognitive disorders.Here,we have screened GLP-1 R targeted com-pounds from Scutellaria baicalensis,which revealed baicalein is a potential GLP-1 R small-molecule agonist.Mitophagy,a selective autophagy pathway for mitochondrial quality control,plays a neuro-protective role in multiple cognitive impairment diseases.We noticed that Glp1r knock-out(KO)mice present cognitive impairment symptoms and appear worse in spatial learning memory and learning capacity in Morris water maze(MWM)test than their wide-type(WT)counterparts.Our mechanistic studies revealed that mitophagy is impaired in hippocampus tissue of diabetic mice and Glp1r KO mice.Finally,we verified that the cognitive improvement effects of baicalein on diabetic cognitive dysfunction occur through the enhancement of mitophagy in a GLP-1 R-dependent manner.Our findings shed light on the importance of GLP-1 R for cognitive function maintenance,and revealed the vital significance of GLP-1R for maintaining mitochondrial homeostasis.Furthermore,we identified the therapeutic potential of baicalein in the treatment of cognitive disorder associated with diabetes.

Objective:To investigate the effect of myopia on retinal vascular geometry in young subjects.Methods:A retrospective cross-sectional study. From June 2018 to December 2018, 235 participants (235 eyes) who took part in routine physical examination in Huadong Sanatorium were included. There were 94 males and 141 females; age was (34.89±6.15) years old; equivalent spherical refraction (SE) was (-3.78±3.25) D. 59 (25.11%, 59/235) were divided into high myopia group (SE≤-6.0 D), along with 131 (55.74%, 131/235) low to moderate myopia group (-0.5 D> SE>-6.0 D), and 45 (19.15%, 45/235) emmetropia group (0.5 D≥SE≥-0.5 D). Retinal vascular geometric measurements, including central retinal arteriolar equivalent (CRAE), central retinal venular equivalent (CRVE), fractal dimension arteriole (FDa), fractal dimension venule (FDv), curvature tortuosity arteriole (CTORTa), curvature tortuosity venule, branch angle arteriole (BAa), branch angle venule, branch coefficient arteriole and branching coefficient venule, were extracted by using a validated computer program. One-way analysis of variance and analysis of covariance were performed to compare the measurements across the high myopia, low to moderate myopia, and emmetropia groups. Linear regression analysis was used to explore the relationship between SE and retinal vascular geometric parameters.Results:The differences in CRAE ( F=65.11), CRVE ( F=61.52), FDa (F=14.26), FDv ( F=8.31), CTORTa ( F=5.07) and BAa (F=6.51) among eys of high myopia group, low to moderate myopia group and emmetropia group remained significant ( P<0.05) after adjusting for age, glycosylated hemoglobin, mean arterial pressure, body mass index, and intraocular pressure. CRAE and CRVE were linearly correlated with the SE ( P<0.05). FDa, FDv, cTORTa and BAa decreased with the decrease of SE in high myopia ( P<0.05). Conclusions:Myopia is associated with the change of the retinal vascular geometric characteristics. With the deepening of myopia, the change of retinal vascular geometric characteristics gradually worsens.

Objective:To observe the relationship between the response to anti-vascular endothelial growth factor (VEGF) drug treatment and single nucleotide polymorphism (SNP) genotype in patients with wet age-related macular degeneration (wAMD).Methods:A retrospective clinical study. From August 2019 to September 2020, 103 eyes of 103 wAMD patients diagnosed in Tianjin Medical University Eye Hospital were included in the study. Among them, there were 59 males (57.28%, 59/103) and 44 females (42.72%, 44/103); the average age was 68.74±7.74 years. The standard logarithmic visual acuity chart was used to detect the Best Corrected Visual Acuity of the affected eye and converted to the logarithmic minimum angle of resolution (logMAR) visual acuity during statistics. Optical coherence tomography was used to detect the central retinal thickness (CRT) of the affected eye. At the same time, the patient's high-density lipoprotein cholesterol (HDL-C) was tested. All eyes were treated with intravitreal injection of anti-VEGF drugs once a month for 3 months. Before the initial treatment, peripheral venous blood from the patient were collected. Interleukin-8 ( IL-8), complement C3 gene ( C3), complement factor H ( CFH), liver lipase ( LIPC), cholesterol ester transfer protein ( CETP), ATP binding cassette subfamily a member 1 ( ABCA1), lipoprotein lipase ( LPL), fatty acid desaturation gene cluster ( FADS1) SNP. According to gene frequency, genotypes are divided into wild type and mutant type were detected. Qualitative data such as the frequency difference of the genotype distribution in the clinical phenotype and the Hardy-Weinberg equilibrium of the genotype distribution were compared with the Chi-square test or Fisher's exact test. Results:There were fewer CRT responders in IL-8 rs4073 mutant (TA+AA) patients than wild-type (TT) [odds ratio ( OR)=0.310, 95% confidence interval ( CI) 0.106-0.910, P<0.05). Among them, after the drug stratification test, the proportion of patients with IL-8 rs4073 locus TT genotype in the conbercept treatment group was less CRT non-responders ( OR=0.179, 95% CI=0.034-0.960, P=0.033). Patients with LIPC rs2043085 mutant (CT+TT) with BCVA increased ≥0.2 logMAR are more likely than wild-type (CC) ( OR=3.031, 95% CI 1.036-8.867, P<0.05); HDL-C level was significantly lower Compared with wild type (CC), the difference was statistically significant ( t=2.448, P=0.016). There was no significant difference in logMAR BCVA and CRT between IL-8 rs4073, LIPC rs2043085 mutant and wild-type patients before treatment ( IL-8 rs4073: Z=-0.198, -1.651; P=0.843, 0.099; LIPC rs2043085: Z=-0.532, -0.152; P=0.595, 0.879). C3 rs 225066, CFH rs800292, CETP rs708272, ABCA1 rs1883025, FADS1 rs174547, LPL rs12678919 have no correlation with anti-VEGF drug treatment response. Conclusions:Patients with wAMD are treated with anti-VEGF drugs. Those with IL-8 rs4073 locus A genotype may be less responsive to CRT. LIPC rs2043085 locus T genotypes may be relatively more responsive to BCVA.

Objective:To explore the different functional connectivity of right caudate nucleus between adults with high myopia and normal vision controls.Methods:The resting-state functional magnetic resonance imaging(fMRI) data were collected from twenty-five high myopia(HM group) and twenty-seven normal vision subjects(NC group). Right caudate nucleus and their subregions(anterior and posterior subregions included) were used as seeds to perform seed-based functional connectivity (FC)analyses at group level under three different frequency bands: convention (0.010~0.080 Hz), slow-5(0.010~0.027 Hz) and slow-4(0.027~0.073 Hz).Results:(1)Compared with NC group, FC of right caudate nucleus with left middle occipital gyrus(MNI: x=-48, y=-84, z=9), left fusiform gyrus(MNI: x=-30, y=-63, z=-12), and right middle frontal gyrus(MNI: x=39, y=12, z=39) were stronger in HM group(all P<0.05, Alphasim Corrected). (2)In HM group, these changed FC were mainly detected in the anterior subregion of right caudate nucleus.(3)The increased FC of right caudate nucleus and its anterior subregion with left middle occipital in HM group were mainly reflected in the frequency band of slow-4(all P<0.05, Alphasim Corrected). Conclusion:The right caudate nucleus in adults with high myopia may play compensatory roles in visual perception and visual attention by enhancing its functional connectivity with visual and visual attentional brain areas.

This study was aimed to observe the clinical effect of low frequency negative pressure meridian viscera regulating sub-health.According to the diagnostic criteria,34 cases of sub healthy subjects were randomly selected.The low frequency negative pressure meridian viscera regulating method was used.By analyzing the cupping spot color feedback conditioning information of the sub healthy subjects and conditioning before and after the synthesis of the four diagnostic methods of digital and quantitative,its effect was evaluated.After 4 weeks of continuous adjustment,34 cases of sub healthy subjects,compared with preconditioning,cupping spot color of the subjects was shallow or disappeared (P ＜ 0.01);after adjusting,the proportion of light red tongue and thin white tongue coating increased obviously (P ＜ 0.05),the proportion of ecchymosis tongue was decreased compared to precoditioning (P ＜ 0.05);after adjustment,core symptoms such as back pain,neck pain,anxiety and irritability,were alleviated or disappeared;after adjustment,the pulse string tightness decreased significantly (P ＜ 0.01).It was concluded that the low frequency negative pressure meridian viscera regulation can significantly improve discomfort symptoms of sub healthy subjects and promote therecovery of tongue,pulse and cupping spot color in sub healthy subjects.This method is worth popularizing and further exploring.

Objective To compare the anticoagulation effect of regional citrate and heparin in patients with sustained low-efficiency hemodialysis (SLED).Method This study was conducted in the teaching hospital of Sichuan University between November 2011 and January 2013.Sixty-three patients suffering from acute kidney injury or end-stage renal diseases (ESRD) were enrolled and further randomized to 2 groups:citrate and heparin anticoagulation treatment groups in SLED.SLED was conducted by Fresenius 4008sARrTplus dialyzer for 8 hours each session,and blood flow was set at 150 ml/min.Prothrombin time (PT),activated partial thromboplastin time (APTT) and platelet (PLT) count were analyzed.Result Sixty-three patients underwent 118 sessions of SLED.Among them,59 patients (93.7％) was discharged after treatment or converted to outpatient intermittent hemodialysis,and 4 patients died of multiple organ failure during hospitalization.Compared with that in the citrate group,both PT and APTT in heparin group was significantly higher [PT:(15.5 ± 2.0) s vs (12.3 ± 2.7) s,P ＜ 0.001 ; APTF:(56.0 ± 10.9) s vs (32.8 ± 6.1) s,P ＜ 0.001 ; respectively] at 2 h during SLED.However,the PT and APTT levels in heparin group decreased afterwards and were similar with those in the citrate groups at 5 h during treatment.There is no difference on PLT counts between these two groups after treatment.Conclusion The anticoagulation effect of regional citrate and heparin was similar in patients when receiving SLED.Regional citrate may be an alternative anticoagulant approach for the patients at high risk of bleeding who require the treatment of SLED.

OBJECTIVE: To explore the risk factors of type 2 diabetes mellitus (T2DM) of Dong nationality in Western Hunan, and to provide a scientific basis for the prevention and treatment of T2DM in the district. METHODS: In the case-control study, the subjects were divided into a T2DM group, an impaired glucose regulation (IGR) group and a normal glucose tolerance (NGT) group through oral glucose tolerance test (OGTT). A questionnaire survey was conducted, and physical measurements and the detection of blood glucose, blood lipids and serum insulin were done. RESULTS: Univariate analysis found significant difference in age, fasting insulin (FINS), HOMA insulin resistance index (HOMA-IRI), HOMA β-cell function index (HOMA-βC), trigalloyl glycerol (TG), high density lipoprotein cholesterol (HDL-C), systolic blood pressure, and diastolic blood pressure in the glucose metabolism among different groups (P<0.05). Body mass index (BMI), waist/hip ratio (WHR), family history of diabetes, number of physical activities per week, dinner taste, fat and protein-rich foods, fresh vegetables and fruits intake were associated with T2DM. Multifactor non-conditional ordinal logistic regression indicated that age was the risk factor of T2DM and IGR. Compared with the group whose age was≤50, the odds ratios of the groups of 5070 were 1.85, 2.83 and 2.64 respectively, P<0.05. The risk of suffering from diabetes of the overweighted or obese people was 2.13 times that of a normal BMI group, P<0.01. The other influencing factors included WHR (OR=2.06), family history of diabetes (OR=11.36), and fat and protein-rich foods (OR=1.90). CONCLUSION The main influencing factors of T2DM of Dong nationality in Western Hunan include age, BMI, WHR, family history of diabetes, fat and protein-rich foods. We must strengthen the health eduation of T2DM of Dong nationality in Western Hunan to reduce the risk of T2DM.
