Objective To explore the diagnostic value of serum levels of fibroblast growth factor 22(FGF22)and CXC chemokine ligand 16(CXCL16)in patients with Parkinson's disease(PD)in cognitive impairment.Methods A total of 125 PD patients admitted to Handan Traditional Chinese Medicine Hospital from June 2022 to June 2023 were selected as the research subjects,and they were separated into a non cognitive impairment group(n=38)and a cognitive impairment group(n=87)based on whether they had cognitive impairment.Enzyme-linked immunosorbent assay(ELISA)was applied to determine the levels of serum FGF22 and CXCL16 in each group.Spearman correlation was applied to analyze the correlation among serum FGF22 and CXCL16 expression levels,Unified Parkinson's Disease Rating Scale(UPDRS)and Montreal Cognitive Assessment(MoCA)scores.Multivariate logistic regression was applied to analyze the factors affecting cognitive impairment in PD patients.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic efficacy of FGF22 and CXCL16 for cognitive impairment in PD patients.Results Compared with the non cognitive impairment group,the expression level of serum FGF22(184.16±14.62ng/ml vs 203.24±12.15ng/ml)in cognitive impairment group and the MoCA score(23.91±3.14 分 vs 26.54±2.31 分)were decreased(t=7.048,4.460,all P＜0.05),while the expression levels of CXCL16(2.59±0.46ng/ml vs 2.06±0.34ng/ml)and the UPDRS score(41.43±5.62 score vs 32.46±4.28 score)were increased(t=6.376,8.782,all P＜0.05),and the differences were statisaically significant.According to Spearman correlation analysis,the expression level of serum FGF22 was negatively correlated with UPDRS score(r=-0.435,P＜0.05),but positively correlated with MoCA score(r=0.742,P＜0.05).The expression level of CXCL16 in serum was positively correlated with UPDRS score(r=0.532,P＜0.05),but negatively correlated with MoCA score(r=-0.623,P＜0.05).Multivariate logistic analysis showed that FGF22 and MoCA scores were protective factors for cognitive impairment in PD patients(all P＜0.05),while CXCL16 and UPDRS scores were risk factors for cognitive impairment in PD patients(all P＜0.05).The combination of serum FGF22 and CXCL16 in the diagnosis of cognitive impairment in PD patients had better AUC than their respective alone diagnoses(Z=2.919,2.437,P=0.003,0.015),with a sensitivity and a specificity of 93.10％and 73.68％,respectively.Conclusion The levels of serum FGF22 and CXCL16 were closely related to cognitive impairment in PD patients,and the combination of the two could better diagnose whether PD patients have cognitive impairment.

Objective:To integrate the best evidence of non-drug intervention of urinary incontinence in elderly women and to formulate practical recommendations.Methods:In this systematic review study, using “elderly woman”,“urinary incontinence”,“bladder training”,“pelvic floor muscle training”,“enuresis”,“leakage of urine” as the key words, the 6S evidence resource pyramid model was used to search in British Medical Journal best practice, Uptodate, World Health Organization, Guidelines International Network, National Institute for Health and Care Excellence, Chinese Medical Association, Scottish Intercollegiate Guideline Network, Registered Nurses Association of Ontario, Cochrane Library, The Joanna Briggs Institute (JBI), New Zealand Guidelines Group, Polish Society of Gynecologists and Obstetricians, PubMed, Embase, Medline, Web of Science, SinoMed, China National Knowledge Infrastructure, WanFang Data, etc. The evidence retrieved included evidence-based knowledge base resources, clinical practice guidelines, expert consensus, systematic review, etc. Data were retrieved from January 1, 2017 to May 1, 2022, and collated from May 2, 2022 to May 25, 2022. Two researchers independently evaluated the quality of literature and extracted data using the AGREE Ⅱ and JBI evidence-based health care center assessment tools. The JBI evidence-based health care center′s evidence pre-rating system and evidence recommendation rating system were applied to rank the evidence; and under the guidance of the evidence structure of JBI, the strength of evidence recommendation was determined and the best evidence was extracted and summarized in combination with the study group discussion and expert opinion.Results:A total of 9 articles were retrieved, including 7 guidelines and 2 systematic reviews; and 6 guidelines were classified as Grade A and 1 as grade B; both 2 systematic reviews were rated as Grade A; 84% (27/32) of the items were evaluated as “Yes”. Evidence were summarized as 34 pieces of best evidence from 6 dimensions, including “overall recommendation, evaluation of type and degree of urinary incontinence, lifestyle change, behavioral therapy, prevention of precipitating factors, intervention in special population”; the flow chart of screening, evaluation, special symptoms, life style and behavior therapy was combed, and the practical suggestions were formed.Conclusions:The overall quality of the literature on non-drug intervention of urinary incontinence in elderly women is high, and the level of evidence is high. Early identification of urinary incontinence types and assessment of disease severity, lifestyle changes, avoidance of predisposing factors and behavioral therapy are the key to non-drug treatment of urinary incontinence in those patients.

ObjectiveTo study the mechanism of Danggui Sinitang in mitigating gouty arthritis （GA） in rats by regulating autophagy via the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. MethodSixty male SD rats were randomly assigned into normal， model， colchicine （0.3 mg·kg^-1）， and low-， medium-， and high-dose Danggui Sinitang （6.54， 13.08， and 26.16 g·kg^-1） groups （n=10） and administrated with corresponding drugs by gavage. The rats in the normal group and model group were administrated with equal volume of normal saline by gavage for 7 days. One hour after administration on day 5， the GA model was established by injecting sodium urate suspension （50 g·L^-1） into the right ankle joint of rats in other groups except the normal group， and the rats in the normal group were injected with sterile normal saline of the same volume. The swelling and pathological changes of the ankle joint were observed. The serum levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and IL-1β were determined. Western blot was employed to determine the protein levels of PI3K， phosphorylated PI3K （p-PI3K）， protein kinase B （Akt）， phosphorylated Akt （p-Akt）， mTOR， phosphorylated mTOR （p-mTOR）， microtubule-associated protein 1 light chain 3 Ⅱ/Ⅰ （LC3Ⅱ/Ⅰ）， autophagy effector Beclin-1， and ubiquitin-binding protein p62 in the synovial tissue. Real-time fluorescent quantitative PCR （Real-time PCR） was employed to determine the mRNA levels of PI3K， Akt， mTOR， LC3， Beclin-1 and p62. ResultCompared with the normal control， the model group showed increased joint swelling index （P<0.01）， elevated serum levels of TNF-α， IL-6， and IL-1β， inflammatory cell infiltration， and fibrous tissue hyperplasia. In addition， the model group showed up-regulated protein levels of PI3K， p-PI3K， Akt， p-Akt， mTOR， p-mTOR， and p62 and mRNA levels of PI3K， Akt， mTOR， and p62 in the synovial tissue， while it showed down-regulated protein levels of LC3Ⅱ/Ⅰ and Beclin-1 and mRNA levels of LC3 and Beclin-1 （P<0.01）. Compared with the model group， medium- and high-dose Danggui Sinitang alleviated the joint swelling （P<0.01）， lowered the serum levels of TNF-α， IL-6， and IL-1β （P<0.05）， and relieved the inflammatory cell infiltration in the synovial tissue of the ankle joint and the fibrous tissue hyperplasia. Moreover， they down-regulated the protein levels of PI3K， p-PI3K， Akt， p-Akt， mTOR， p-mTOR， and p62 and the mRNA levels of PI3K， Akt， mTOR， and p62 in the synovial tissue （P<0.05）， while they up-regulated the protein levels of LC3Ⅱ/Ⅰ and Beclin-1 and the mRNA levels of LC3 and Beclin-1 （P<0.05）. ConclusionDanggui Sinitang， especially at a high dose， can inhibit PI3K/Akt/mTOR signaling pathway to improve autophagy in the synovial tissue， thereby mitigating GA.

Objective:To determine a relationship between ultrasound shear wave elastography (SWE) and pathological lessions of renal tissues in children with chronic kidney disease (CKD).Methods:It was a cross-sectional observational study, involving children admitted to the Department of Pediatrics of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January to December 2021 with definite pathological diagnosis through kidney biopsy. The SWE was used to determine the Young's modulus (elastic modulus) of the cortex and medulla of the upper, middle, and lower poles of the kidney. The renal histopathology was classified or graded. The statistical method was used to analyze the relationship between Young's modulus of the inferior polar cortex (YM cor) and medulla (YM med) of the right kidney and renal pathology. Results:The study included 110 children with definite pathological diagnosis through renal biopsy, aged (10.1±3.4) years old (2-17 years old), with 55 males (50.0%). The body mass index was (20.6±2.4) kg/m 2, and mean arterial pressure was (95±24) mmHg. There were 94 patients (85.4%) with CKD stage 1, 8 patients (7.3%) with CKD stage 2, and 8 patients (7.3%) with CKD stage 3. There was no significant difference of YM cor and YM med in the upper and middle poles of the right kidneys, and YM med in the lower poles of right kidneys in CKD patients with different stages (all P>0.05). Both YM cor [(15.75±3.36) kPa] and YM med [(13.50±2.43) kPa] of CKD stage 3 patients were significantly higher than those of CKD stage 1 patients [(12.94±2.45) kPa, (11.88±2.23) kPa](both P<0.05). There was no significant difference of YM cor and YM med in the lower poles of right kidneys between stage 1 and stage 2 CKD patients (both P>0.05). YM cor[(17.93±3.23) kPa] and YM med [(15.50±1.48) kPa] in patients with crescentic glomerulonephritis were higher than those in patients with focal segmental glomerulosclerosis [(12.71±2.42) kPa, (11.57±2.63) kPa] and mesangial proliferative glomerulonephritis [(12.73±2.04) kPa, (11.48±2.10) kPa](all P<0.05). There was no significant difference of YM cor and YM med between focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis (both P>0.05). YM cor [(16.30±2.63) kPa] and YM med [(15.54±1.59) kPa] of Lee's Ⅳ grade of IgA nephropathy were higher than those of Lee's Ⅲ grade [(13.32±2.70) kPa, (12.57±2.50) kPa](both P<0.05), while the International Study of Kidney Disease in Children grade of purpura nephritis had no significant correlation with YM cor and YM med (both P>0.05). YM cor [(15.41±2.37) kPa] and YM med [(13.82±2.59) kPa] of interstitial fibrosis/tubular atrophy (T1/T2) group of IgA nephropathy mixed with purpura nephritis were significantly higher than those of T0 group's [(12.99±2.40) kPa, (11.79±2.05) kPa] (both P<0.05). Moreover, crescent formation (C1) group had a higher YM cor [(14.21±2.77) kPa] and YM med [(12.80±2.47) kPa] than those in C0 group [(12.73±2.15) kPa, (11.59±1.97) kPa] (both P<0.05), while YM cor and YM med were unrelated to the mesangial hypercellularity (M), endocapillary cellularity (E), segmental sclerosis or adhesion (S) indicators (all P>0.05). In lupus nephritis patients, YM cor ( r=0.744, P=0.035) and YM med ( r=0.728, P=0.009) were favorably linked with the chronic index, but not with the activity index (both P>0.05). Conclusions:Renal interstitial fibrosis/tubular atrophy and crescentic development are connected with YM cor and YM med at the lower pole of the kidney as measured by SWE. SWE can be used to assess the chronic renal lesions in children with CKD in the early and middle stages. It may develop into a new noninvasive way to assess renal pathology.

Objective:To learn about the iodine nutritional status of children aged 8 to 10 years in Xiamen City after the reform of salt industry system, and to provide scientific basis for reasonable prevention and control of iodine deficiency disorders.Methods:From 2017 to 2019, 6 districts were selected each year in Xiamen City 5 sampling districts were divided according to the oriation of east, west, south, north and center in each district. One town (street, hereinafter refered as to town) was selected from each sampling district. One primary school was selected from each town. For each primary school, at least 40 non-boarding children aged 8 to 10 years (age balanced, half male and half female) were selected. Edible salt samples in the households and random urine samples of children aged 8 to 10 years were collected, and salt iodine and urinary iodine contents were measured, while thyroid volume was examined by B-ultrasound.Results:From 2017 to 2019, the coverage rate of iodized salt in Xiamen City was 97.34% (1 206/1 239), 96.89% (1 214/1 253), and 93.33% (1 175/1 259), respectively; the consumption rate of qualified iodized salt was 96.13% (1 191/1 239), 95.61% (1 198/1 253), and 91.58% (1 153/1 259), respectively; the median urinary iodine was 182.90, 182.81, 164.00 μg/L, respectively. The prevalence of goiter of boys and girls was 1.01% (19/1 889) and 2.26% (42/1 862), respectively.Conclusions:After the reform of salt industry system, the iodine nutritional status of children aged 8 to 10 years is generally at an appropriate level in Xiamen City. However, the consumption rate of qualified iodized salt is reduced, which increases the risk of iodine deficiency for residents. Therefore, we should strengthen the propaganda of scientific iodine supplement, maintain a high consumption rate of qualified iodized salt, and prevent the harm of iodine deficiency.

Objective: To investigate the current prevalence of latent tuberculosis infection (LTBI) among residents living in Nanchuan District, Chongqing Municipality, so as to provide the evidence for formulating LTBI control measures. Methods: The residents living in one street and one township from Nanchuan District were randomly selected using the multistage cluster sampling method during the period between January and April, 2020, and their demographic information, smoking history, history of alcohol consumption, history of contacts with tuberculosis patients and Bacillus Calmette-Guérin ( BCG ) vaccination scars were collected. The infection of Mycobacterium tuberculosis was detected using interferon gamma release assay ( IGRA ), and a positive IGRA test and exclusion of active tuberculosis was defined as LTBI. The prevalence of LTBI was descriptively analyzed among the study subjects. Results: Totally 1 000 residents were recruited, including 381 males and 619 females, with a male to female ratio of 0.62∶1. The mean age was ( 45.87±18.40 ) years. Among all participants, there were 222 smokers ( 22.20% ), 247 subjects consuming alcohol (24.70%), 62 subjects with a history of contacts with tuberculosis patients ( 6.20% ) and 904 subjects with BCG scars ( 90.40% ). A total of 198 residents were diagnosed with LTBI (19.80% prevalence), and a higher prevalence rate of LTBI was seen in men than in women ( 23.36% vs. 17.61%; χ2=4.911, P=0.027 ). The prevalence of LTBI was significantly higher in married/divorced/widowed residents than in unmarried residents ( 24.22% vs. 2.01%; χ2=49.514, P<0.001 ), and significantly greater prevalence was found in smokers than in non-smokers ( 27.93% vs. 17.48%; χ2=11.871, P=0.001 ). The prevalence of LTBI appeared a tendency towards a rise with age ( χ2trend=59.100, P<0.001 ) and body mass index ( χ2trend=9.479, P=0.002 ). Conclusions The prevalence of LTBI is high among residents living in Nanchuan District, notably among elder, male smokers with high body mass index. Risk monitoring and timely interventions are required.

Objective:To analyze the clinical and pathological characteristics, treatment and prognosis of renal changes in patients with Kimura disease and improve the clinicians′ understanding on renal manifestations of Kimura disease.Methods:The clinical data of Kimura disease patients with definite diagnosis and detailed data in Peking Union Medical College Hospital from January 1980 to August 2020 were retrospectively analyzed. The patients were divided into renal impairment group and non-renal impairment group according to whether the kidney was involved or not and the related clinical data between the two groups were compared. The patients presenting with nephrotic syndrome were followed up.Results:There were 60 patients with Kimura disease confirmed by pathological diagnosis with 48 males. The median age was 33(3, 62) years old, and the median duration was 36(12, 111) months. There were 18 cases complicated with renal injury in 49 patients with complete routine urine and renal function examination and the main manifestations of renal injury were proteinuria and/or microscopic hematuria. There was no significant difference at age, sex and absolute value of eosinophils between the two groups (all P>0.05). Compared with the renal inpairment group, patients in non-renal inpairment group had longer course of disease, higher levels of hypersensitive C-reactive protein and erythrocyte sedimentation rate, and lower median values of total eosinophils and total IgE, but there was no statistically significant difference (all P>0.05). Among the patients with renal involvement, 6 patients met the diagnostic criteria for nephrotic syndrome, and 5 of them completed renal biopsies. The renal pathological diagnosis was membranous nephropathy in 2 cases and minimal change disease in 3 cases, and no interstitial eosinophil infiltration was found in renal biopsy tissues. These patients had a good response to glucocorticoids and/or immunosuppressive therapy, and achieved complete remission of nephrotic syndrome; at the same time, lymphadenopathy caused by Kimura disease could be well controlled. Conclusions:Kimura disease can combine with various renal lesions, and the pathology of nephrotic syndrome can be membranous nephropathy or minimal change nephropathy. After energetic treatment of glucocorticoids and/or immunosuppressive therapy, nephrotic syndrome can be completely relieved, and lymphadenopathy can be well controlled. The relationship between Kimura disease and renal disease needs further study.

Objective:To study the effect of high flow humidification oxygen inhalation on hypoxemia in patients undergoing cardiac surgery and the effect of postoperative weaning time.Methods:A total of 80 patients with hypoxemia after cardiac surgery from January 2018 to January 2020 were selected for the study, according to the random number table, they were divided into the observation group and the control group, 40 cases each.The control group was treated with noninvasive positive pressure ventilation, while the observation group was treated with high flow humidification and oxygen absorption. The weaning time, the changes of the arterial oxygen partial pressure (PaO 2), partial pressure of carbon dioxide (PaCO 2), oxygenation index (PaO 2/FiO 2), pH value, spontaneous breathing frequency (RR), heart rate before and after treatment 2 h, 6 h, 24 h, and the incidence of complications were compared between the two groups. Results:The weaning time in the observation group was (35.51±4.61) h, and that in the control group was (44.04±3.85) h, the difference was statistically significant( t value was 8.982, P<0.01). The PaO 2 in the observation group at 2, 6, 24 h after treatment were (73.96±4.32), (79.82±3.61), (94.82±2.71) mmHg(1 mmHg=0.133 kPa), and those in the control group were (70.72±3.10), (75.63±3.88), (90.27±3.55) mmHg, the differences were statistically significant( t values were 3.854, 5.000, 6.443, P<0.01). The PaO 2/FiO 2 in the observation group at 2, 6, 24 h after treatment were (239.45±18.74), (269.85±20.09), (291.83±17.30) mmHg, and those in the control group were (226.74±20.72), (251.12±16.74), (279.65±19.40) mmHg, the differences were statistically significant( t values were 2.877, 4.530, 2.964, P<0.01). The RR in the observation group at 2, 6, 24 h after treatment were (24.74±2.03), (22.61±1.86), (18.63±2.05) times/min, and those in the control group were (26.07±1.89), (24.24±1.73), (20.11±1.87) times/min, the differences were statistically significant( t values were 3.033, 4.058, 3.373, P<0.01). The heart rate in the observation group at 2, 6, 24 h after treatment were (83.32±4.88), (76.06±4.71), (70.34±3.82) times/min, and those in the control group were (86.06±3.29), (80.91±4.31), (75.71±6.22) times/min, the differences were statistically significant( t values were 2.944, 4.805, 4.653, P<0.01). The total incidence of complications in the observation group was 7.50%(3/40), and that in the control group was 25.00%(10/40), the difference was statistically significant( χ 2 value was 4.501, P<0.05). Conclusions:High flow humidification and oxygen absorption is well for patients with hypoxemia after cardiac surgery, which effectively improve the blood gas index, shorten the weaning time, reduce the incidence of complications, and have good safety, which is worth popularizing.

Objective:To compare CT with MRI on the accuracy in TNM staging of pancreatic ductal adenocarcinoma (PDAC) based on the 8th American Joint Committee on Cancer System and Pathological Staging.Methods:From October 2013 to October 2019, 105 patients who had pathologically confirmed PDAC treated at the Affiliated Wuxi No.2 People’s Hospital of Nanjing Medical University were retrospectively studied. Of 52 patients who met the inclusion criteria, there were 32 males and 20 females, with age ranging from 45 to 84 years (mean 66.1 years). Based on the 8th American Joint Committee on Cancer System and Pathological Staging, CT was compared with MRI in their accuracies in categorizing TNM and staging of PDAC.Results:Forty-three of 52 patients who underwent curative resection had a mean tumor size of (3.4±1.2) cm, compared with tumor sizes of (3.3±1.2) cm and (3.3±1.4) cm on CT and MRI, respectively. No significant differences were observed between gross pathological examination and CT ( P>0.05) or MRI ( P>0.05). The accuracy of T, N, and M categories on CT versus (vs) MRI was 97.7% (42/43) vs 97.7% (42/43), 79.1% (34/43) vs 76.7% (33/43), and 100% (9/9) vs 88.9% (8/9), respectively. No significant differences were observed between the two modalities ( P>0.05). The overall accuracy of PDAC staging on CT vs MRI was 82.7% (43/52) vs 76.9% (40/52), respectively. There was also no significant difference between the two modalities ( P>0.05). Conclusion:Both CT and MRI had similar accuracies in categorizing TNM and staging of PDAC. However, the accuracies of T and M stages were higher than that of the N stage for these two imaging modalities.
