Objective This study investigated the epidemic characteristics and spatio-temporal dynamics of hemorrhagic fever with renal syndrome (HFRS) in Qingdao City,China. Methods Information was collected on HFRS cases in Qingdao City from 2010 to 2022. Descriptive epidemiologic,seasonal decomposition,spatial autocorrelation,and spatio-temporal cluster analyses were performed. Results A total of 2,220 patients with HFRS were reported over the study period,with an average annual incidence of 1.89/100,000 and a case fatality rate of 2.52%. The male:female ratio was 2.8:1. 75.3% of patients were aged between 16 and 60 years old,75.3% of patients were farmers,and 11.6% had both "three red" and "three pain" symptoms. The HFRS epidemic showed two-peak seasonality:the primary fall-winter peak and the minor spring peak. The HFRS epidemic presented highly spatially heterogeneous,street/township-level hot spots that were mostly distributed in Huangdao,Pingdu,and Jiaozhou. The spatio-temporal cluster analysis revealed three cluster areas in Qingdao City that were located in the south of Huangdao District during the fall-winter peak. Conclusion The distribution of HFRS in Qingdao exhibited periodic,seasonal,and regional characteristics,with high spatial clustering heterogeneity. The typical symptoms of "three red" and"three pain" in patients with HFRS were not obvious.

OBJECTIVE To study the pharmacokinetics and tissue distribution of cannabidiol(CBD)-cholesterol succinate monoester-g-carboxymethyl chitosan (CCMC) nano-micelles in rats, and to evaluate its anti-inflammatory effect. METHODS CBD- CCMC nano-micelles were prepared by dialysis method and the properties were characterized. SD rats were divided into CBD group and CBD-CCMC nano-micelles group with 6 rats in each group. The rats were given 100 mg/kg CBD and CBD-CCMC nano- micelle by intragastric administration, respectively (based on the CBD load). Blood was collected from the posterior ophthalmic venous plexus at 0.5, 1, 1.33, 1.5, 1.75, 2, 4, 8, 24, 48 h after administration. The heart, liver, spleen, lung, kidney and muscle tissues of rats were separated at 0.25, 1.5, 10 and 24 h after administration of CBD and CBD-CCMC nano-micelle with the same dose. The drug content in plasma and tissues was determined, the pharmacokinetic parameters were calculated, and the tissue distribution was analyzed. The inflammatory model of Caco-2 cells was induced by lipopolysaccharide, after 24 h of treatment with 5, 10, and 15 µg/mL CBD and CBD-CCMC nanomicelles (based on loaded CBD), its anti-inflammatory activity was investigated by measuring cell viability, transepithelial electrical resistance (TEER) and inflammatory cytokines IL-1β, IL-8 and TNF-α. RESULTS The prepared CBD- CCMC nano-micelles had a particle size of (230.6±1.8) nm, a polydispersity index of 0.170±0.053, a Zeta potential of (-13.5± 1.2) mV, an encapsulation rate of (86.35±0.56)% and a drug loading of (9.18±0.32)%, respectively; the solubility was 68.240 μg/mL. The pharmacokinetic results showed that the AUC0-48 h, AUC0-∞, half-life time and peak concentration of CBD-CCMC nano- micelle group were significantly increased/extended compared with CBD group (P<0.05 or P<0.01). The results of the tissue distribution study showed that at the same time point, the drug distribution concentration of CBD-CCMC nanomicelles in the rat tissue was higher than that in the CBD group. Research on anti-inflammatory effects shows that compared with CBD of the same mass concentration, CBD-CCMC nano-micelles can significantly increase cell viability (P<0.05 or P<0.01), enhance TEER, and reduce the levels of IL-8, IL-1β and TNF-α in cells (P<0.01), and the secretion levels of inflammatory cytokines IL-8, IL-1β and TNF- α were significantly decreased (P<0.01). CONCLUSIONS CBD-CCMC nano-micelles can increase the plasma concentration and tissue distribution concentration of CBD, and improve anti-inflammatory activity of CBD.

ObjectiveTo investigate the prevalence of overweight, obesity and fatty liver disease (FLD) in adult residents in a suburban area of Shanghai, and to explore the relationship between these conditions and eating out of home (EOH). MethodsAdult residents from Zhongshan Street, Songjiang, Shanghai, were invited to report their frequency of EOH and undergo a physical examination using B-ultrasonography from May to September 2017. Binary logistic regression analyses were conducted to examine the relationship between EOH and conditions of overweight, obesity, and FLD. ResultsAmong the final sample size of 6 608 participants, the prevalence rates of overweight, obesity, and FLD were 41.65%, 14.71% and 38.29%, respectively. After adjusting for potential confounders, logistic analyses revealed that participants with an EOH frequency > once/week had a 1.44-fold higher prevalence of obesity (P=0.006), a 1.35-fold higher prevalence of overweight/obesity (P=0.005), and a 1.36-fold higher prevalence of FLD (P=0.008). ConclusionThe prevalence of overweight, obesity, and FLD is relatively high in Songjiang, Shanghai. EOH may be a risk factor for these diseases, and residents are recommended to reduce the frequency of EOH.

Objective:To investigate the resting state functional connectivity changes of the " triple network model" composed of salient network (SN), executive control network (ECN) and default mode network (DMN) in patients with acute mild traumatic brain injury (mTBI).Methods:From August 2020 to December 2021, forty-five acute mTBI patients (mTBI group) and 40 healthy controls (HC group) with matched sex, age, and education were included.The Montreal cognitive assessment (MoCA) scale was used to evaluate the cognitive status of all subjects.The resting state network (RNS) was established based on independent component analysis (ICA), and the SN, ECN and DMN were extracted, then functional network connectivity (FNC) was analyzed.Subsequently, the correlation between functional connectivity abnormalities and the performance of cognitive impairment was analyzed.SPSS 19.0 was used for statistical analysis and double sample t test was used for comparison between the tow groups. Results:Compared with HC group, mTBI group had enhanced functional connectivity between SN(L-insula) (MNI: x, y, z=-36, 15, 0, t=3.693)and ECN (left superior parietal gyrus, L-SPG) (MNI: x, y, z=-33, -69, 54, t=3.333)(FDR adjust, P<0.05), and decreased functional connectivity between DMN(left superior frontal gyrus, L-SFG) (MNI: x, y, z=-30, 30, 42, t=-4.063)and DMN(L-angular gyrus)(MNI: x, y, z=-21, -66, 33, t=-4.101)(FDR adjust, P<0.05). For FNC analysis, functional network connectivity in SN(IC26)-DMN(IC8) was enhanced in the acute mTBI group and decreased between SN(IC26)-DMN(IC12) and ECN(IC3)-DMN(IC12). The changes of left superior parietal gyrus functional connection were negatively correlated with MoCA score ( r=-0.627, P<0.01), and SN (IC26) -DMN(IC12) connection was positively correlated with MoCA score ( r=0.411, P=0.005). Conclusions:In patients with acute mTBI, the resting functional connectivity changes within and between the networks of the " triple network model" composed of SN, ECN and DMN, and is related to the decline of cognitive function.This will help to better understand the neuropathological mechanism of acute mTBI and post-traumatic cognitive impairment, and may become an effective imaging marker for identifying and predicting cognitive impairment after mTBI.

ObjectiveTo investigate the effect of combination of proprioceptive neuromuscular facilitation (PNF) rope training and repetitive transcranial magnetic stimulation (rTMS) on upper limb motor function of stroke patients with hemiplegia. MethodsFrom March, 2021 to February, 2022, 90 stroke inpatients with hemiplegia in the Department of Rehabilitation Medicine, the Second Affiliated Hospital of Guangxi Medical University were divided into control group (n = 30), rope group (n = 30) and combination group (n = 30) randomly. All the groups received routine rehabilitation, while the control group received routine PNF training, the rope group received PNF rope training, and the combination group received PNF rope training and rTMS, for four weeks. They were assessed with Functional Test for the Hemiplegic Upper Extremity-Hong Kong version (FTHUE-HK), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI) before and after treatment. ResultsThe scores of FTHUE-HK, FMA-UE and MBI increased in all the three groups after treatment (t > 2.167, P < 0.05), and they were more in the combination group than in the rope group (P < 0.05), and in the rope group than in the control group (P < 0.05). ConclusionThe combination of PNF rope training and rTMS is more effective on motor function of upper limbs of stroke patients with hemiplegia than PNF training alone.

Objective:To establish a performance validation method for mNGS applied in BALF samples.Method:Hela cells were used as a representative of host cells, and simulated BALF samples were prepared by adding different concentrations of Hela cells, seven species of isolated pathogens (including Streptococcus pneumonia, Hemophilus influenza, Klebsiella pneumonia, Candida albicans, Cryptococcus neoformans, Aspergillus fumigatus, and Adenovirus), and interfering substances to sterile normal saline. Clinical BALF samples were collected simultaneously, and the results of mNGS were evaluated using traditional detection methods as a reference. The limit of detection (LOD), precision, anti-interference ability, stability, and accuracy of mNGS were determined. Results:In the simulated samples, the LOD of Streptococcus pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, Candida albicans, Cryptococcus neoformans, Aspergillus fumigatus, and Adenovirus were 150, 262, 102, 67, 96, 83 CFU/ml, and 439 copies/ml, respectively. The repeatability of the detection results for all pathogens of simulated positive BALF samples was 100%. The anti-interference test showed that the higher the concentration of human DNA, the fewer pathogen sequences detected by mNGS. Escherichia coli and Shigella sonnei were used to evaluate the ability of mNGS to distinguish closely related species. The results showed that the system could stably distinguish Escherichia coli and Shigella sonnei when the concentration of Shigella sonnei was 4, 000 CFU/ml. The stability test results showed that there was no significant change in the number of pathogen sequences detected whether after 1 to 3 freeze-thaw cycles or storage at 4 ℃, -20 ℃, or -80 ℃ for 36 h. Compared with traditional detection methods, the accuracy of 17 clinical samples was 82.4%(14/17). Continuous evaluation of clinical BALF samples simultaneously tested by mNGS and traditional methods at Tongji Hospital from October 25, 2021, to September 14, 2022, showed that the accuracy of mNGS compared to bacterial culture, fungal culture, mycobacterial culture, Mycobacterium tuberculosis culture, and conventional PCR techniques was 67.5%(472/699), 81.5%(570/699), 92.3%(335/363), 96.4%(350/363), and 86.8%(132/152), respectively. Compared with conventional PCR techniques, the accuracy of mNGS for detecting Pneumocystis jirovecii, Adenovirus, and Mycoplasma pneumoniae was 89.4%(84/94), 93.3%(56/60), and 87.1%(61/70), respectively. Conclusion:By preparing simulated BALF samples and using traditional detection methods as a reference, the performance characteristics of mNGS in detecting BALF samples can be preliminarily evaluated.

Objective:To investigate the effect of ultrasound-guided lumbar quadratus muscle plane block combined with general anesthesia on the analgesic effect during and after laparoscopic colon cancer radical surgery in elderly patients.Methods:A prospective study was conducted on 61 elderly patients who underwent radical colon cancer surgery at the Changsha Central Hospital Affiliated to South China University from May 2022 to February 2023, with American Society of Anesthesiologist (ASA) grades Ⅱ to Ⅲ. They were randomly divided into SA and GA groups using a random number table method, with 31 patients in the SA group and 30 patients in the GA group. The SA group received ultrasound-guided plane block of the upper lumbar quadratus muscle in the arcuate ligament combined with general anesthesia, while the GA group received simple general anesthesia. Record the mean artery pressure (MAP) and heart rate (HR) of two groups of patients at the time of entering the operating room (T 0), 5 minutes before skin incision (T 1), at skin incision (T 2), 30 minutes after surgery (T 3), at surgery end (T 4), and during anesthesia resuscitation and extubation (T 5); The Visual Analogue Scale (VAS) of two groups of patients at T 5, upon returning to the ward (T 6), 6 hours (T 7), 12 hours (T 8), 24 hours (T 9), and 48 hours (T 10) after surgery were recorded; The dosage of sufentanil, remifentanil, and propofol used during surgery, anesthesia recovery time, total number of analgesic pump presses within 48 hours after surgery, Lovett muscle strength score, early postoperative recovery, and adverse reactions within 48 hours after surgery were also recorded. Resultsl:The MAP and HR of the SA group were lower than those of the GA group at T 1-5 (all P<0.05); The VAS score of the SA group was lower than that of the GA group at T 5-10 (all P<0.05); The intraoperative dosage of propofol, remifentanil, and sufentanil in the SA group was lower than that in the GA group (all P<0.05); The anesthesia recovery time and first time out of bed in the SA group were earlier than those in the GA group (all P<0.05); The total number of times the analgesic pump was pressed within 48 hours after surgery was less than that of the GA group ( P<0.05); The incidence of nausea and vomiting within 48 hours after surgery in the SA group was lower than that in the GA group ( P<0.05). There was no statistically significant difference in postoperative Lovett muscle strength score, hospital stay, and dizziness incidence between the two groups of patients (all P>0.05). Conclusions:Ultrasound-guided lumbar quadratus muscle plane block on the arcuate ligament can significantly reduce the dosage of intraoperative general anesthesia drugs and postoperative analgesics in elderly patients undergoing laparoscopic colon cancer surgery, reduce postoperative pain scores, effectively alleviate postoperative pain, and thus advance the patient′s first time out of bed activity, reduce postoperative complications, and promote rapid recovery.
