ObjectiveTo analyze the epidemiological and clinical characteristics of surveillance cases in a sentinel hospital for pertussis in Jiangxi Province in 2019, and to provide corresponding references for the prevention and control of pertussis. MethodsCase investigation of pertussis was conducted among sentinel hospital surveillance cases, collecting their basic information, epidemiological characteristics, clinical characteristics, and other information. ResultsA total of 125 pertussis surveillance cases were investigated in 2019, including 73 clinically diagnosed cases (58.40%) and 52 confirmed cases (41.60%). The age of onset was mainly concentrated in children under 5 years old (108 cases, 86.40%), with the largest number of cases in infants aged less than 1-year-old (48 cases, 38.40%). Most cases had a history of receiving pertussis vaccine before onset (110 cases, 88.00%), and the intervals between the onset date and the date of last dose of pertussis vaccine in the 1‒2 doses group were significantly shorter than that in the 3‒4 doses group (U=-5.990, P<0.001). Probable household transmission of pertussis was found in 3 cases. All cases had cough symptoms, mainly manifested as whooping cough (77 cases, 61.60%), in addition to other main clinical manifestations, such as fever (76 cases, 60.80%), vomiting (30 cases, 24.00%), conjunctival congestion (27 cases, 21.60%), and inspiratory whoop (16 cases, 12.80%). A total of 73 cases (58.40%) experienced complications, including 1 death case. All the cases had multiple medical visit experiences before this visit, with an interval of 2 (0,3) days between the onset date and the first visit date. The misdiagnosis rate at the first medical visit was 88.00% (110/125), and the misdiagnosis rate of the first visit in secondary and primary hospitals was significantly higher than that in tertiary hospitals, exhibiting a statistically significant difference (χ²=21.582, P<0.001). ConclusionThe clinical symptoms of pertussis cases are often atypical, and the first diagnosis is prone to misdiagnosis, so it’s necessary to further strengthen the early diagnosis capabilities for pertussis cases in healthcare institutions, especially in the primary healthcare institutions.

Objective: To analyze the serotypes and drug resistance of Salmonella isolated from food-borne disease surveillance samples in Longwan District, Wenzhou City, Zhejiang Province, so as to provide evidence for the prevention and treatment of Salmonella infection. Methods: Salmonella strains isolated from feces or anal swabs of patients with foodborne diarrhea in Longwan District People's Hospital from 2018 to 2024 were collected. After re-identification, slide agglutination test was used to identify serotypes. The drug susceptibility test of live Salmonella strains was performed using the broth microdilution method, and the resistance patterns were analyzed. Results: A total of 2 293 samples were collected, and 186 strains of Salmonella were isolated, with a detection rate of 8.11%. The detection rate was higher from May to October. A total of 28 Salmonella serotypes were identified, with S. typhimurium (72 isolates, 38.71%), S. enteritidis (31 isolates, 16.67%), and S. London (30 isolates, 16.13%) being dominant. Among the 121 Salmonella live strains, 20 strains were susceptible to 14 antibacterial drugs. A total of 101 strains were resistant to antibacterial drugs, and the drug resistance rate was 1.65%-67.77%, with the drug resistance rate of ampicillin being the highest, and the drug resistance rate of imipenem was the lowest. S. typhimurium had the highest resistance rate to tetracycline (78.26%). S. enteritidis had the highest resistance rate to ampicillin (100.00%). S. London had the highest resistance rate to tetracycline (66.67%). Fifty-five types of drug resistance patterns were detected, showing a number of drug resistance of 1-10, of which 76 strains were multi-drug resistant, accounting for 75.25%. The predominant multidrug resistance patterns were ampicillin/sulbactam-cefazolin-ampicillin-nalidixic acid (10.53%), tetracycline-ampicillin-nalidixic acid (9.21%), and ampicillin/sulbactam-ampicillin-nalidixic acid (7.89%). Conclusions Salmonella strains isolated from foodborne diseases in Longwan District were mainly detected in summer and autumn. S. typhimurium, S. enteritidis, and S. London were the predominant serotypes. The drug resistance of Salmonella to different antibacterial drugs was different, and the drug resistance spectrum showed diversity.

Objective To investigate the effect of ultrasound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament on postoperative analgesia and inflammation response in elderly patients undergoing robot-assisted laparoscopic radical prostatectomy.Methods A total of 60 elderly patients who had undergone robot-assisted laparoscopic radical prostatectomy from June 2022 to June 2023 were randomly divided into a group of ultra-sound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament combined with general anesthesia(observation group,n = 30)and a general anesthesia group(control group,n = 30).Both groups received patient-controlled intravenous analgesia after surgery.The first compression time of an analgesic pump and the numbers of effective compression and remedial analgesia were recorded.The VAS scores at postsurgical hours 2,12,24,and 48 during rest and coughing were recorded.Interleukin-6(IL-6)and systemic immunoinflammatory index(SII)at one day before surgery and two hours,one day and three days after surgery were recorded.Anal exhaust time,length of postoperative hospital stay and occurrence of adverse reactions were recorded.Results The observation group,as compared with the control group,had significantly longer first compression time of an analgesic pump and had fewer numbers of effective compressions and remedial analgesic administrations(P<0.05).The VAS scores during rest and coughing in the observation group were lower than those in the control group at postsurgical hours 2,12,24,and 48(P<0.05).As compared with one day before surgery,both IL-6 and SII in the two groups increased at 2 hours,1,and 3 days after surgery,but the changes in the observation group were lower than those in the control group(P<0.05).As compared with the control group,the observation group had shorter anal exhaust time and length of postoperative hospital stay,and a lower incidence of adverse reactions(P<0.05).Conclusions Ultrasound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament can provide better postoperative analgesia,reduce inflammatory response and accelerate postoperative recovery in elderly patients undergoing robot-assisted laparoscopic radical prostatectomy.

OBJECTIVE To investigate the effect mechanism of Gualou guizhi granule on neurological function and synaptic plasticity in rats with cerebral ischemia-reperfusion injury. METHODS The rats were randomly divided into sham operation group， model group and Gualou guizhi granule group （3.6 g/kg）， with 6 rats in each group. The cerebral ischemia-reperfusion injury model was established by the suture occlusion method. Two hours after modeling， the model rats were given relevant medicine or normal saline intragastrically， once a day， for 7 consecutive days. After the last medication， the neurological function of rats was evaluated [calculated by modified neurological severity scores （mNSS） and corner turning percentage]； the neuronal apoptosis rate of brain histiocyte in the ischemic side of rats was detected in each group； the positive expressions of growth associated protein 43 （GAP43） and microtubule associated protein 2 （MAP2） were detected； protein expressions of neuron-specific nuclear protein （NeuN）， synaptophysin-1 （Syn-1）， postsynaptic density protein-95 （PSD-95）， peroxisome proliferators-activated receptor γ （PPARγ）， brain-derived neurotrophic factor （BDNF） and tropomyosin receptor kinase B （TrkB）， as well as mRNA expressions of NeuN， Syn-1 and PSD-95 were detected. RESULTS Compared with the model group， mNSS， corner turning percentage and neuronal apoptotic rate were decreased significantly in Gualou guizhi granule group （P＜0.01）； GAP43 represented weak immunoreactivity， and MAP2 represented moderate immunoreactivity； protein expressions of NeuN， Syn-1， PSD-95， PPARγ， BDNF， TrkB and mRNA expressions of Syn-1， NeuN， PSD-95 were all increased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Gualou guizhi granule can promote synaptic plasticity by activating BDNF/TrkB signaling pathway， thus playing a protective role in cerebral ischemia-reperfusion injury in rats.

Objectives To investigate the relationship between self-reported occupational noise exposure and levels of plasma inflammatory cytokines in asthmatic patients. Methods A total of 910 adult asthmatic patients were selected as the study subjects, and their occupational noise exposure history and other related information were collected. The peripheral blood samples were collected from the patients, and the expression levels of plasma soluble CD14 (sCD14), complement factor D (CFD), Eotaxin-11 (CCL11), and IL-9 were determined. The relationship between self-reported occupational noise exposure and the expression levels of the four inflammatory cytokines in patients’ plasma were analyzed using multiple linear regression models. The interactions between confounding factors and self-reported occupational noise exposure were further analyzed by interaction analysis. Results The plasma CCL11, sCD14 and CFD expressions in asthmatic patients with self-reported occupational noise exposure were significantly higher than those in patients without the exposure (P<0.05). After adjusting for confounding factors, compared with patients reporting no occupational noise exposure, the plasma CFD expression was increased by 0.17 (95% CI: 0.02, 0.31) natural logarithm units in patients with self-reported occupational noise exposure. During remission, the levels of plasma CCL11 and sCD14 in asthmatic patients with self-reported occupational noise exposure were increased by 0.27 (95% CI: 0.05, 0.49) and 0.22 (95% CI: 0.02, 0.41) natural logarithm units, respectively, when compared with patients without the exposure. Interaction analysis showed that self-reported occupational noise exposure had significant multiplicative interaction with smoking or pet ownership on plasma CCL11 or CFD expressions in asthmatic patients (all P<0.05). Conclusion Self-reported occupational noise exposure is significantly associated with increased expression levels of plasma CFD, CCL11, and sCD14 in adult asthmatic patients.

ObjectiveTo evaluate the effectiveness of Gandou decoction （GDD） by analyzing theclinical efficacy of GDD combined with speech training on the treatment of dysarthria with endoretention of damp-heat in Wilson's disease （WD）， so as to provide more clinical data and theoretical support for the selection of appropriate treatment schemes for WD patients with dysarthria with endoretention of damp-heat. MethodA total of 60 eligible WD patients with dysarthria with endoretention of damp-heat were selected and divided into a control group and a treatment group according to the random grouping method， with 30 cases in each group. The control group was treated with speech training + sodium dimercaptopropanesulfonate （DMPS）， and the treatment group was combined with GDD on the basis of the control group， with eight days as a course of treatment for 32 days. The total clinical effectiveness rate （Goldstein clinical classification）， dysarthria grading assessment from China Rehabilitation Research Center， TCM syndrome scores， 24-hour urine copper content， and modified Frenchay dysarthria rating scale scores of the two groups were compared before and after treatment. ResultAfter treatment， the total effective rate of the observation group was 90.0% （27/30）， and that of the control group was 70.0% （21/30）. The total effective rate of the observation group was significantly higher than that of the control group （Z=-1.986，P<0.05）. After treatment， the modified Frenchay dysarthria score， dysarthria grading assessment from China Rehabilitation Research Center， and 24-h urine copper in the two groups were significantly increased （P<0.05， P<0.01）， and the TCM syndrome score was significantly decreased （P<0.01）. Compared with the control group after treatment， except for the respiratory and jaw score， the modified Frenchay dysarthria score of the observation group was significantly increased （P<0.05， P<0.01）. The dysarthria grading from China Rehabilitation Research Center and 24-h urine copper content were significantly increased （P<0.01）， and the observation group had better efficacy. During the study period， there were no serious adverse reactions such as fever， rash， oral and eyelid mucosal swelling， exfoliative dermatitis， vomiting， diarrhea， or allergic shock during copper excretion treatment of DPMS and oral administration of GDD. ConclusionGDD combined with speech training can improve the symptoms and efficacy of WD patients with dysarthria with endoretention of damp-heat and enhance the patients' living standard to a certain extent， which can be widely used in clinics.

Non-alcoholic fatty liver disease(NAFLD) is the most common clinical chronic liver disease with a global incidence of about 25%, which could progress to liver fibrosis, liver cirrhosis, and hepatocellular carcinoma, and posing a serious threat to human health. At present, China has not approved any therapeutic drugs for marketing, and the research and development of new drugs is imminent. It is difficult to achieve great efficacy with a single medication due to the complex mechanism of NAFLD. The combination of several drugs with different pharmacological mechanisms is an inevitable trend for the future treatment of NAFLD, which is expected to reduce the adverse effects of the drug and play a synergistic effect to produce better efficacy. This paper reviews the latest clinical research progress of NAFLD combined drugs, so as to provide a reference for the subsequent new drug development and clinical rational drugs application of NAFLD.

OBJECTIVE:Cold water immersion methods are not standardized in terms of operational indicators such as immersion temperature,duration and depth,leading to controversy over the efficacy of recovery from exercise fatigue in skeletal muscle.In this article,we analyze the effects of cold water immersion on muscle injury,muscle soreness and muscle strength recovery under different factors,in order to find the best immersion implementation plan,and thus provide evidence for the recovery of muscle fatigue. METHODS:A search of CNKI,WanFang Data,Web of Science,and PubMed databases was conducted for relevant literature published from January 1,2000 to August 15,2023.A total of 4 759 articles were initially retrieved,with 4 735 articles excluded through screening and 24 articles finally included.The Physical Therapy Evidence Database Scale was used to assess the methodological quality of the included literature,and Stata-MP 16 software was used to perform effect size combinations,subgroup analyses,Meta-regression,sensitivity tests,and publication bias analyses. RESULTS:(1)The article included a total of 24 randomized controlled trial studies,including 617 subjects,with overall high legal quality.(2)Meta-analysis showed that cold water immersion can significantly reduce creatine kinase blood value[standardized mean difference(SMD)=-0.17,95％confidence interval(CI):-0.29 to-0.05,P<0.01],alleviate muscle pain(SMD=-0.60,95％CI:-0.81 to-0.38,P<0.01),and promote maximum muscle strength recovery(SMD=0.17,95％CI:0.05 to 0.30,P<0.01).(3)Subgroup analysis showed that:The immersing regimen with water temperature>14 ℃(SMD=-0.48,95％CI:-0.76 to-0.20,P<0.01)and duration of 12-14 minutes(SMD=-0.38,95％CI:-0.61 to-0.15,P<0.01)had the best effect in reducing creatine kinase blood values,and had a more significant intervention effect on endurance exercise(SMD=-0.45,95％CI:-0.71 to-0.20,P<0.01),while the immersion regimen with water temperature<10 ℃(SMD=-0.61,95％CI:-0.79 to-0.43,P<0.01),duration<12 minutes(SMD=-0.76,95％CI:-0.98 to-0.53,P<0.01),and immersion depth above the iliac spine(SMD=-0.74,95％CI:-0.97 to-0.52,P<0.01)had the best effect on relieving muscle soreness,and had a more significant analgesic effect after endurance exercise(SMD=-0.42,95％CI:-0.61 to-0.22,P<0.01).(4)Meta regression showed that immersion water temperature,immersion duration,and exercise type were important regulatory factors affecting the effect size of creatine kinase;immersing water temperature and immersing depth were important regulatory factors affecting the effect size of visual analogue scale score,while exercise type was an important regulatory factor affecting the maximum isometric muscle strength effect size. CONCLUSION:(1)Evidence of extremely low to moderate strength suggests that cold water immersion can effectively reduce muscle damage,alleviate muscle soreness,and promote muscle strength recovery.(2)In terms of reducing muscle injury,immersion water temperature,immersion duration,and exercise type are significant regulatory factors that affect the efficacy of immersing.Among them,immersion water temperature>14 ℃ and duration of 12-14 minutes are the best solutions to reduce muscle injury after exercise,and the immersing effect is better for endurance exercise.(3)In terms of reducing muscle soreness,immersion water temperature and immersion depth are important regulatory factors that affect the intervention effect.Among them,immersion water temperature<10 ℃,duration<12 minutes,and immersing depth above the iliac spine are the best solutions to reduce muscle soreness,and have a better analgesic effect after endurance exercise.(4)In terms of promoting muscle strength recovery,exercise type is a key regulatory factor that affects the maximum isometric muscle strength effect.
