Objective:To deeply analyze the epidemiological characteristics and changing trends of intestinal infectious diseases in China, and provide scientific evidence for the prevention and control of intestinal infectious diseases.Methods:The incidence data of notifiable intestinal infectious diseases in China from 2013 to 2022 were collected from China Disease Prevention and Control Information System. Descriptive statistical method was used to analyze the distributions of intestinal infectious diseases in China, and the annual change rate and seasonal index were calculated.Results:During 2013-2022, intestinal infectious diseases were reported nationwide, with the cases accounting for 43.50% of all notifiable infectious disease cases. The average reported incidence rate was 224.50/100 000, showing a decreasing trend year by year (average annual percent change=-6.45%, t=-2.76, P=0.025). The top 5 intestinal infectious diseases were hand foot and mouth disease (HFMD) (130.40/100 000), other infectious diarrhea (80.18/100 000), dysentery (7.45/100 000), acute hemorrhagic conjunctivitis (2.49/100 000) and viral hepatitis E (1.92/100 000). The incidences of dysentery, HFMD, typhoid fever/paratyphoid fever, viral hepatitis A and acute hemorrhagic conjunctivitis all showed decreasing trends year by year (all P<0.05), while the incidences of hepatitis E and other infectious diarrhea showed no significant changes with year (both P>0.05). The incidence of intestinal infectious diseases was high during May to October, with the peak in June. The incidence rate of intestinal infectious diseases was significantly higher in men than in women (all P<0.05). The HFMD, other infectious diarrhea and dysentery cases were mainly children aged 0-5 years, while the cholera, hepatitis A, hepatitis E, typhoid fever/paratyphoid fever and acute hemorrhagic conjunctivitis cases were mainly farmers aged ≥20 years. The annual reported incidence rate of intestinal infectious diseases was higher in southern provinces (283.66/100 000) than in northern provinces (142.63/100 000), and the annual reported incidence rate of intestinal infectious diseases was higher in coastal provinces (279.52/100 000) than in inland provinces (181.78/100 000), the differences were all significant (both P<0.001). Conclusions:During 2013-2022, the incidence of intestinal infectious diseases decreased significantly in China, with HFMD and other infectious diarrhea as the main diseases. Strengthened surveillance for intestinal infectious diseases should be carried out in key groups, such as children living scatteredly and farmers, and targeted prevention and control measures should be taken according to the epidemiological characteristics of different diseases to effectively reduce the incidence of intestinal infectious diseases.

Objective To explore the influencing factors of prognosis and nursing strategies in sepsis combined with gastrointestinal dysfunction.Methods The clinical data of 102 patients with sepsis and gastrointestinal dysfunction who were admitted to Traditional Chinese Medicine Hospital of Guangdong Province(The Second Affiliated Hospital of Guangzhou University of Chinese Medicine)between June 2022 and December 2023 were retrospectively analyzed.According to the prognosis within 30 d,the patients were assigned to death group(n=38)or survival group(n=64).Clinical indexes were compared between the two groups.The main influencing factors of prognosis were analyzed by Logistic regression,and targeted nursing strategies were summarized.Results The mortality in the patients with sepsis and gastrointestinal dysfunction was 37.25%(38/102).Univariate analysis showed that age,Sequential Organ Failure Assessment(SOFA)score,Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score,gastrointestinal failure(GIF)score,and stay time in ICU were all influencing factors of prognosis in patients with sepsis and gastrointestinal dysfunction(all P<0.05).Logistic regression analysis showed that age≥65 years,SOFA score>6,APACHEⅡscore>17,GIF score>3,and stay time in ICU>7 d were independent risk factors of poor prognosis in patients with sepsis and gastrointestinal dysfunction(all P<0.05).Conclusion The poor prognosis of patients with sepsis and gastrointestinal dysfunction is related to age,SOFA score,APACHEⅡscore,GIF score,and stay time in ICU.It is essential to take preventive and nursing measures for these risk factors to reduce the incidence of poor prognosis.

Objective To investigate the expression level and clinical significance of long non-coding RNA(LncRNA) growth arrest specific gene-antisense 1(GAS8-AS1) in papillary thyroid microcarcinoma(PTMC) patients. Methods We investigated the expression profile of GAS8-AS1 in tissue samples of patients with PTMC as well as nodular goiter(NG) by quantitative real-time polymerase chain reaction(RT-qPCR). Results GAS8-AS1 in cancer tissue was down-regulated in PTMC patients compared with adjacent thyroid tissue and NG samples(P<0.05). Lower level of GAS8-AS1 was also correlated with central cervical lymph node metastasis(CLNM, P<0.05). The area under the ROC curve for GAS8-AS1 was up to 0.717 3 in CLNM prediction(P<0.05). Conclusion GAS8-AS1 may act as a potential biomarker for PTC diagnosis and CLNM prediction.

Objective To analyze the factors associated with treatment outcomes of dive-related spinal cord decompression sickness (DCS).Methods A retrospective analysis was made in 95 patients with dive-related spinal cord DCS (with an age range of 43 ± 11).Such medical data as dive data,clinical medical data,spinal cord magnetic resonance imaging (MRI),electrophysiological data,latency of DCS symptoms upon completion of diving,the relationship between symptom onset and the interval from the start of HBO therapy to the termination of HBO therapy were collected for analysis.The severity and treatment outcomes of spinal cord DCS were assessed by the Boussuges grade system during the acute stage and 3 months after treatment.The treatment outeomes of spinal cord DCS were classified into complete recovery and incomplete recovery.All the patients were treated with the widely-recognized treatment protocol.Results Fifty-six patients (59％) had complete recovery,3 months after DCS seizure,and 39 patients (41％) had incomplete recovery following 3 months of treatment.Complete recovery rate in the young patients was higher than that in the old ones.The complete recovery rate of the patients with normal spinal cord MRI detection results was higher than that of the patients with abnormal MRI detection results,and the complete recovery rate of the patients with normal electrophysiological detection results was higher than that of the patients with abnormal electrophysiological detection results.The complete recovery rate of the patients with Boussuges scores ≤7 at onset time was higher than that of the patients with Boussuges scores of over 7.The complete recovery rate of the patients without back pain was higher than that of the patients with acute back pain.The complete recovery rate of the patients with over 50-minute symptom latency upon surfacing was higher than that of the patients with less than 50-minute symptom latency.The complete recovery rate of the patients with less than 4.5-hour time interval between symptom onset and HBO therapy was higher than that of the patients with over 4.5-hour time interval.Conclusions The patients with younger age,normal MRI detection results,normal electrophysiological data,Boussuges scores ≤7,no complaint of back pain after surfacing,longer symptom latency upon dive completion,and shorter time interval between symptom onset and HBO therapy would have better treatment outcomes.

ObjectiveTo detect the fiber structure and volume differences in frontal lobe between patients with amnestic mild cognitive impairment (aMCI) and normal control.MethodsT1 -weighted magnetic resonance imaging and diffusion tensor imaging were obtained in 28 aMCI patients and 25 normal controls.Volumes,fiber fractional anisotropy (FA),fiber apparent diffusion coefficient (ADC),fiber number,and average fiber length of frontal lobe in the two groups were measured.ResultsVolumes of left frontal lobe ( ( 337.35 ± 20.45 ) cm3 ) in aMCI group were smaller than control ( (358.54 ± 27.26) cm3 ) ( t =- 3.223,P =0.002 ).Numbers of short range fiber in left frontal lobe ( 16985 ± 892) were significantly increased relative to control ( 16387 ±752) ; while numbers of long range fiber (3214 ± 185 ) were reduced compared with control (3425 ± 277 ),and ADC values increased ( t =2.621,P =0.012; t =-3.714,P =0.001 ; t =17.595,P=0.000).In aM CI group,numbers of long range fiber in right frontal lobe were reduced (2895 ± 343 vs.3451 -± 230,t =- 7.011,P =0.000),and ADC values were increased ( t =4.443,P =0.000).In aMCI group,numbers of long range fiber in left frontal lobe were positively correlated with scores of mini-mental state examination ( MMSE ) ( r =0.457,P =0.015 ),while ADC values of long range fiber in left frontal lobe were negatively correlated with scores of MMSE ( r=-0.415,P=0.028).ConclusionThe structure and fiber connectivity are affected in aMCI patients and the lesion of connectivity in left frontal lobe are related to the severity of symptom.

Objective To compare the results of three kinds of heart preservative fluids,namely histidine-tryptophan-ketoglutarate(HTK)solution,Fuwai modified solution(FWM)and St.Thomas' Hospital cardioplegic solution number 2(St.Thomas-Ⅱ)for the preservation of isolated rat hearts under low temperature.Methods Fifty-four male SD rats were randomly divided into HTK,FWM and ST-Ⅱ groups(18 each),and each group was divided into three subgroups(6 each)according to different duration of preservation under low temperature(4,6 and 8 hours).The hearts were harvested and then mounted on the Langendorff apparatus and perfused with K-H buffer solution for determination of the baseline hemodynamic values(HR,LVSP,?dp/dtmax and CF).The isolated hearts were then arrested and stored in different preservative solution as mentioned at 4℃ for 4,6 or 8 hours.The hemodynamic values were measured before cardiac arrest and after cardiac reperfusion in Langendoff model,and the recovery rates of the values were calculated.The hearts were finally sectioned after reperfusion for the observation of morphological changes with light microscope.Results With the same hypothermic preservation time,the recovery rates of hemodynamic values were significantly higher,and the changes in myocardial structures were obviously less in HTK and FWM groups than in ST-Ⅱ group(P0.05).Conclusions HTK and FWM solutions are more effective than St.Thomas-Ⅱsolution in preservation of isolated heart under low temperature with the same storage duration.The effect of HTK solution for preservation of isolated heart descended with the prolongation of preservation time,especially so after 8 hours.
