Compared to other nanomaterials, manganese-based nanomaterials exhibit excellent biocompatibility and have become a significant focus in the research of breast cancer diagnosis and treatment.

Rheumatoid arthritis(RA)is an autoimmune disease with the basic pathological manifestation of synovial inflammation.Symmetric poly-articular pain and swelling are the main symptoms in clinical practice,and even extra-articular manifestations and comorbidities such as interstitial fibrosis and coronary artery disease are triggered,which seriously affect the quality of life of patients.Traditional Chinese medicine(TCM)has achieved good clinical efficacy in the prevention and treatment of RA with the advantages of multi-pathway,multi-target,multi-component,and less toxic side effects,and plays an important role in the treatment of RA.Recently,many studies have demonstrated that Chinese medicine monomers and Chinese herbal compound can control inflammation,reduce angiogenesis,induce apoptosis of synovial fibroblasts,and inhibit their proliferation,invasion and migration by regulating the PI3K/Akt signaling pathway,so as to play a key role in the treatment of RA.For this reason,the article summarizes current knowledge regarding the PI3K/Akt signaling pathway and its role in RA,as well as summarizes the current research progress of TCM in the treatment of RA by regulating the PI3K/Akt signaling pathway.The aim of this review is to provide theoretical bases for the prevention and treatment of RA and the development of new drugs.

Objective:To investigate the effect of tele-rehabilitation program on ataxic dysarthria following stroke.Methods:A total of 101 patients with stroke and dysarthria who received treatment at The First People's Hospital of Huzhou between January 2021 and October 2023 were included in this study. They were divided into an observation group ( n = 51) and a control group ( n = 50) using the random number table method. Patients in the control group received conventional family rehabilitation guidance, while those in the observation group participated in a tele-rehabilitation program. All patients were treated for 12 weeks. Before and 12 weeks after the intervention, the Frenchay Dysarthria Assessment (FDA) and speech clarity tests were used to assess speech function. Changes in FDA scores and speech clarity scores post-intervention were compared with pre-intervention scores. The observation group was further divided into mild, moderate, and severe groups based on FDA scores, and the differences in effect of tele-rehabilitation program on ataxic dysarthria among the three groups after the intervention were compared. Results:At 12 weeks after intervention, both the observation and control groups showed improvements in FDA scores and speech clarity [observation group: (43.88 ± 16.13) points, (68.65 ± 16.99)%; control group: (49.68 ± 12.09) points, (62.36 ± 14.20)%] compared with their baseline measurements [observation group: (55.12 ± 12.63) points, (57.96 ± 13.48)%; control group: (54.16 ± 10.69) points, (57.84 ± 12.78)%] ( t = 12.23, -14.01, 12.42, -13.86, all P < 0.001). Moreover, the observation group showed significant improvements compared with the control group ( t = 2.04, -2.01, both P < 0.05). At 12 weeks after intervention, both the mild and moderate groups showed improvements in FDA scores and speech clarity score [mild group: (31.41 ± 3.08) points, (82.94 ± 6.97)%, moderate group: (40.08 ± 4.67) points, (70.92 ± 6.26)%] compared with their baseline measurements [mild group: (42.24 ± 6.78) points, (70.53 ± 7.98)%, moderate group: (56.17 ± 4.65) points, (57.58 ± 6.54)%, t = 10.06, -20.25, 45.21, -21.34, all P < 0.001]. There were no significant improvements in the severe group for FDA scores and speech clarity score [(74.20 ± 4.29) points, (38.90 ± 5.80)%] compared with their baseline measurements [(74.50 ± 4.01) points, (37.50 ± 4.74)%, t = 1.96, -1.44, both P > 0.05]. Conclusion:The tele-rehabilitation program can improve post-stroke ataxic dysarthria, particularly showing significant effectiveness for patients with mild to moderate ataxic dysarthria.

Objective To investigate the genetic diversity and genetic differentiation of different geographical isolates of Gohieria fusca.. Methods G. fusca isolates were sampled from Wuhu (WH), Bengbu (BB) and Bozhou cities (BZ) of Anhui Province and Jiaxing City of Zhejiang Province (JX). Mitochondrial cytochrome b (Cytb) and ribosomal internal transcribed spacer (ITS) genes were amplified in WH, BB, BZ and JX isolates of G. fusca using PCR assay. The gene sequences were edited and aligned using the software Chromas 2 and DNASTAR 1.00, and the haplotype, haplotype diversity (Hd) and nucleotide polymorphism (Pi) of each isolate were calculated using the software DnaSP 5.10.00. The genetic differentiation among isolates (F_st) and gene flow value (N_m) were estimated using the software MEGA 10.2, and a phylogenetic tree was built. Tests of neutrality and analysis of molecular variance (AMOVA) were performed using the software Arlequin 3.1 and a haplotype network was built based on the Median-Joining network using the software Network 10.2. Results PCR assay showed that the sizes of the Cytb and ITS genes were 372 bp and 1 301 to 1 320 bp, respectively. All four isolates of G. fusca presented high genetic diversity based on mitochondrial Cytb and ITS genes (Hd = 0.804, Pi = 0.006 91). AMOVA showed genetic differentiation among geographical isolates of G. fusca (F_st = 0.202 40, P < 0.05), and the genetic variation was mainly caused by intra-population variations (79.76%). Gene flow analysis showed a high level of gene flow among G. fusca isolates (N_m > 1). Tests of neutrality based on Cytb gene measured a Tajima’s D value of −1.796 31 (P < 0.05) and a Fu’s FS value of −3.293 98 (P < 0.05) in WH isolate of G. fusca, indicating population expansion in WH isolate of G. fusca. Haplotype network analysis and phylogenetic analysis revealed no remarkable geographical distribution pattern among different geographical isolates of G. fusca. All four isolates of G. fusca presented high genetic diversity (Hd = 0.985, Pi = 0.011 97). AMOVA showed moderate level of genetic differentiation between four isolates (F_st = 0.104 62, P < 0.05). The tests of neutrality based on ITS genes measured a Tajima’s D value of −6.088 20 and a Fu’s FS value of −1.935 99 (both P > 0.05) in the whole isolate of G. fusca, indicating no obviously population expansion. Conclusions The four geographical isolates of G. fusca have high genetic diversity and remarkable genetic differentiation. Since a high level of gene flow is detected among different geographical isolates of G. fusca, no obvious geographical distribution pattern of G. fusca is found.

BACKGROUND: Clinical trial evidence is limited to identify better topical non-steroidal anti-inflammatory drugs (NSAIDs) for treating knee osteoarthritis (OA). We aimed to compare the clinical efficacy and safety of flurbiprofen cataplasms (FPC) with loxoprofen sodium cataplasms (LSC) in treating patients with knee OA. METHODS: This is an open-label, non-inferiority randomized controlled trial conducted at Peking University Shougang Hospital. Overall, 250 patients with knee OA admitted from October 2021 to April 2022 were randomly assigned to FPC and LSC treatment groups in a 1:1 ratio. Both medications were administered to patients for 28 days. The primary outcome was the change of pain measured by visual analog scale (VAS) score from baseline to day 28 (range, 0-10 points; higher score indicates worse pain; non-inferiority margin: 1 point; superiority margin: 0 point). There were four secondary outcomes, including the extent of pain relief, the change trends of VAS scores, joint function scores measured by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and adverse events. RESULTS: Among 250 randomized patients (One patient without complete baseline record in the flurbiprofen cataplasms was excluded; age, 62.8 ± 10.5 years; 61.4% [153/249] women), 234 (93.6%) finally completed the trial. In the intention-to-treat analysis, the decline of the VAS score for the 24-h most intense pain in the FPC group was non-inferior, and also superior to that in the LSC group (differences and 95% confidence interval, 0.414 (0.147-0.681); P <0.001 for non-inferiority; P = 0.001 for superiority). Similar results were observed of the VAS scores for the current pain and pain during exercise. WOMAC scores were also lower in the FPC group at week 4 (12.50 [8.00-22.50] vs . 16.00 [11.00-27.00], P = 0.010), mainly driven by the dimension of daily activity difficulty. In addition, the FPC group experienced a significantly lower incidence of adverse events (5.6% [7/124] vs . 33.6% [42/125], P <0.001), including irritation, rash and pain of the skin, and sticky hair uncovering pain. CONCLUSIONS This study suggested that FPC is superior to LSC for treating patients with knee OA in pain relief, joint function improvement, and safety profile.

Purpose: Gastric cancer (GC) is the second most lethal cancer globally and is associated with poor prognosis. Fatty acid-binding proteins (FABPs) can regulate biological properties of carcinoma cells. FABP5 is overexpressed in many types of cancers; however, the role and mechanisms of action of FABP5 in GC remain unclear. In this study, we aimed to evaluate the clinical and biological functions of FABP5 in GC. Materials and Methods: We assessed FABP5 expression using immunohistochemical analysis in 79 patients with GC and evaluated its biological functions following in vitro and in vivo ectopic expression. FABP5 targets relevant to GC progression were determined using RNA sequencing (RNA-seq). Results: Elevated FABP5 expression was closely associated with poor outcomes, and ectopic expression of FABP5 promoted proliferation, invasion, migration, and carcinogenicity of GC cells, thus suggesting its potential tumor-promoting role in GC. Additionally, RNA-seq analysis indicated that FABP5 activates immune-related pathways, including cytokinecytokine receptor interaction pathways, interleukin-17 signaling, and tumor necrosis factor signaling, suggesting an important rationale for the possible development of therapies that combine FABP5-targeted drugs with immunotherapeutics. Conclusions These findings highlight the biological mechanisms and clinical implications of FABP5 in GC and suggest its potential as an adverse prognostic factor and/or therapeutic target.

Objective:To reevaluate the upper limit of normal (ULN) of serum alanine aminotransferase (ALT) by retrospectively analyzing the ALT levels in healthy people in Ningbo area.Methods:A total of 56 140 people who underwent health examination and detection of liver biochemical indexes in the Affiliated Hospital of Medical School of Ningbo University and Yinzhou Huamao Hospital of Ningbo from 2018 to 2020 were enrolled. After excluding relevant factors that may lead to liver injury, 11 411 people were included to compare the difference of serum ALT levels among different genders and age groups (20 to 29 years, 30 to 39 years, 40 to 49 years and 50 to 59 years) to determine the ALT ULN in different gender groups. Statistical methods were performed using two independent samples t test and analysis of variance. Results:The serum ALT of males was (19.20±7.90) U/L, which was higher than that of females ((13.75±6.17) U/L), with statistical significance ( t=41.16, P<0.001). The serum ALT ULN in males and in females were 35 U/L and 26 U/L, respectively. The serum ALT levels of 20 to 29, 30 to 39, 40 to 49 and 50 to 59 years old groups were (15.48±7.61) U/L, (16.21±7.40) U/L, (17.36±7.52) U/L and (18.77±7.57) U/L, respectively.The difference was statistically significant ( F=71.51, P<0.001). Serum ALT level in 50 to 59 years old group was higher than that in 20 to 29 years old group, and the difference was statistically significant ( t=13.11, P<0.01). In males, the ALT ULN of 20 to 29 years old was the lowest of 34.43 U/L, and highest of 35.29 U/L in 40 to 49 years old. In females, the ALT ULN in the 20 to 29 years old group was the lowest of 23.01 U/L, and the ALT ULN in the 50 to 59 years old group was the highest of 30.79 U/L. ALT ULN increased with age in females. The serum ALT of males was higher than that of females in all age groups ( t=29.55, 26.91, 13.43 and 4.62, respectively, all P<0.05). Conclusions:The serum ALT level is significantly correlated to gender and age. The serum ALT ULNs of healthy adult are 35 U/L in males and 26 U/L in females in Ningbo area.

Objective:To observe the pressure level and hair cortisol level of pregnant women, and explore the influence of pregnancy stress on gestational diabetes mellitus(GDM) and underlying mechanism.Methods:The eligible pregnant women at People′s Hospital of Henan Province from January 2020 to December 2021 were selected. Pregnancy stress scale(PSS) was used for stress assessment at 10 th-12 th gestational weeks. The hair of pregnant women was collected to detect cortisol at 24 th-28 th gestational weeks. Oral glucose tolerance test was performed at the 24 th, 28 th, 32 nd and 36 th gestational weeks to diagnose GDM. The endpoint event of follow-up was GDM. Results:Among 498 pregnant women, 20(4.0%) had no stress, 321(64.5%) had mild stress, 128(25.7%) had moderate stress, and 29(5.8%) had severe stress. There was a significant positive correlation between maternal hair cortisol levels and the total PSS score. The hair cortisol level in severe stress group was significantly higher than that in other groups, and the hair cortisol level in GDM group was significantly higher than that in non-GDM group. There were significant differences in GDM-free survival curves among different stress groups( χ2=15.975, P=0.001). Cox multivariate regression showed that severe stress was an independent risk factor for GDM. The area under the receiver operating characteristic curve is 0.747(95% CI 0.545-0.950, P=0.028). Conclusions:Severe stress during pregnancy is an independent risk factor for the occurrence of GDM, and has a certain ability to predict GDM. Cortisol may play a role in the process through which stress mediates GDM. For pregnant women experiencing severe stress, it is necessary to assess stress levels dynamically and take measures accordingly.

Objective: To analyze the characteristics, diagnosis and treatment status of Takotsubo syndrome (TTS) of Chinese patients. Methods: Complete literature review was performed to summarize Chinese TTS cases between 2007 and 2018. Results: A total of 131 literatures were included including 160 TTS patients (age (58.3±14.7) years). There were 137 female patients (85.6%) in this cohort, the age was (59.6±14.0) years. There were 124 cases (77.5%) of stress-evoking factors, of which 83 cases (66.9%) were self-stress factors. There were 97 cases (60.6%) complained of chest pain and 15 cases (9.4%) with syncope. Forty-eight cases (30.0%) presented with cardiogenic shock. CK-MB and cTnT/I increased in 109 cases (80.1%). There were 124 cases (77.5%) presented with ST segment elevation on electrocardiogram, which were common in lead V₂-V₅. Echocardiography results were available in 128 cases (80.0%), reduced left ventricular ejection fraction (<50%) was reported in 78 cases (73.6%). Coronary angiography was performed in 133 patients (83.1%), of which 126 patients (94.7%) had normal coronary arteries or single non-significant stenosis. One hundred and thirty-eight patients (87.3%) were apical type. The misdiagnosis rate on admission was 96.9% (155/160), of which 141 cases (88.1%) were misdiagnosed as acute myocardial infarction. Nitroglycerin was used in 36 patients (30.3%). Angiotensin converting enzyme inhibitor or angiotensin Ⅱ receptor antagonist were used in 38 patients (31.9%). β blockers were used in 46 patients (38.7 %). Dopamine was used in 22 cases (18.5%) and norepinephrine was used in 12 cases (10.1%). Intra-aortic balloon counter pulsation was used in 5 cases (3.1%). Cardiopulmonary resuscitation was performed in 9 cases (5.6%). Cardiac function recovery time was 7 (6, 15) days. The average InterTAK diagnosis score was (51.5±18.1) points, and value was>70 points in 2 cases (1.3%). There were 92 patients in the high-risk group, and there were 3 recurrent TTS cases. Five patients died. Conclusions: TTS incidence tends to be young and dominates in female in China. The misdiagnosis rate is extremely high on admission. Most patients are treated with medication.

Allyl alcohol is an intermediate widely used in industrial production activities, which has caused many occupational damage in China. In this paper, the data of a case of skin damage and clinical cure of inhalation pneumonia caused by occupational allyl alcohol exposure were analyzed and summarized. The patient accidentally inhaled large amounts of allyl alcohol at work and had skin exposure, which was mainly manifested as aspiration pneumonia, respiratory failure, eye damage and skin bullae. After short-term hormone shock therapy, mechanical ventilation, infection prevention, local treatment and other comprehensive treatment, the patient was clinically cured. This case suggests that chemical pneumonia and respiratory failure may be caused by inhalation of allyl alcohol, and skin bullae may be caused by skin contact. Early treatment and hormone use should be emphasized.
