Objective To investigate the therapeutic effect of cnithol on acute pancreatitis(AP)rats and its regulatory mechanism on phosphoinositol 3-kinase(PI3K)/protein kinase B(Akt)signaling pathway.Methods SPF-grade SD male rats were randomly divided into control group,model group(50 μg·kg-1 hyranin+10 mg·kg-1 LPS),positive control group(2 mg·kg-1 dexamethasone),experimental-L group(20 mg·kg-1 osthol)and experimental-H group(40 mg·kg-1 osthol),experimental-H+740Y-P group(40 mg·kg-1 osthol+2 mg·kg-1 PI3K activator 740Y-P),15 mice in each group.The activities of amylase and lipase in serum of rats were detected by automatic biochemical analyzer 24 h after the last administration.The levels of inflammatory factors tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)in serum,the content of malondialdehyde(MDA)and the activity of superoxide dismutase(SOD)in pancreas were detected by enzyme-linked immunosorbent assay(ELISA).Hematoxylin-eosin(HE)staining was used to observe the pathological changes of pancreatic tissue and score the pathological damage.Western blot was used to detect the expression of PI3K/Akt pathway related proteins in rat pancreas.Results The activities of serum amylase in control group,model group,positive control group,experimental-H group and experimental-H+740Y-P group were(135.67±12.89),(1 027.84±32.16),(174.31±15.27),(186.70±17.39)and(835.92±28.78)U·mL-1,respectively;the contents of TNF-α were(35.69±3.10),(223.54±15.23),(48.76±4.25),(52.31±4.68)and(208.46±13.65)pg·mL-1,respectively;the contents of MDA were(2.15±0.14),(6.37±0.42),(2.78±0.17),(2.81±0.15)and(5.96±0.36)nmol·mg-1,respectively;the histopathological injury scores were 1.12±0.07,10.23±0.38,3.14±0.21,3.25±0.23 and 9.68±0.40,respectively;p-PI3K/PI3K ratios were 0.82±0.05,1.96±0.15,1.07±0.06,1.10±0.07 and 1.69±0.14,respectively.The above indexes were compared with the control group in the model group,the positive control group,experimental-H group and the model group,and the above indexes of experimental-H+740Y-P group and experimental-H group,and the differences were statistically significant(all P＜0.05).Conclusion Gossetin can play a therapeutic role in AP,and its mechanism may be related to the inhibition of PI3K/Akt signaling pathway.

To explore the situation of 8 common respiratory pathogens in children with acute respiratory infection (ARI) from 2021 to 2022.The retrospective study selected 8 710 ARI patients from September 2021 to August 2022 in the Maternal and Child Health Hospital of Gansu Province as the study object, patients aged 0 to 17 years old, including 5 048 male children and 3 662 female children. Indirect immunofluorescence was used to detect 8 common respiratory pathogens, including influenza virus A (FluA), influenza virus B (FluB), parainfluenza virus (PIV), respiratory syncytial virus (RSV), adenovirus (ADV), Mycoplasma pneumoniae (MP), Chlamydia pneumoniae (CP), and Coxsackie virus group B (CoxB) IgM antibodies. χ² test was used to analyze the results. The results showed that 1 497 of 8 710 children with ARI were positive, with a positive rate of 17.19%. The detection rate of MP among 8 common respiratory pathogens was 11.34%, accounting for 66.0%, followed by FluB, CoxB, PIV, RSV, ADV, FluA and CP, accounting for 13.83%, 9.55%, 6.01%, 2.61%, 1.47%, 0.40% and 0.13%, respectively. Respiratory tract viruses (FluA, FluB, RSV, ADV, PIV, CoxB) accounted for 33.86%.There were significant differences in the detection rates of PIV, ADV and MP among children of different genders (χ²=6.814, 5.154 and 17.784, P<0.05). The detection rate of school-age children (6-17 years old) was the highest, accounting for 33.27% (184/553). The detection rates of 8 common respiratory pathogens in patients with ARI were higher in spring and winter and lower in summer and autumn. To sum up, from 2021 to 2022, MP and FluB infection were dominant in ARI patients in our hospital. The peak period of 8 common respiratory pathogens was in spring and winter. The physical examination rate of 8 common respiratory pathogens in ARI patients aged 6-17 years old was the highest.

Phosphodiesterase 4 (PDE4) is an important member of the phosphodiesterase enzyme family that specifically catalyzes the hydrolysis of cyclic adenosine monophosphate (cAMP), activates the downstream phosphorylation cascade pathway by altering cAMP concentration, and is strongly associated with multiple diseases. Inhibition of PDE4 is clinically investigated as a therapeutic strategy in a broad range of disease areas, including respiratory system diseases, autoimmune disorders, central nervous system diseases, and dermatological conditions. However, the incidence of adverse reactions such as nausea and vomiting is relatively high in the marketed PDE4 inhibitors, which has stalled their clinical development. In this review, we provide an overview of the clinical progression and safety issues of the marketed PDE4 inhibitors. We also review the main causes underlying PDE4-mediated adverse effects by combining the structural analysis of the PDE4 protein, the mechanism of action of PDE4 inhibitors, and the related side effect mechanism research, aiming to provide a reference for the development of safe and effective PDE4 inhibitors.

Human epididymis protein 4(HE4) is a secretory glycoprotein found in human distal epididymis epithelial cells. It is often used in the early diagnosis, efficacy evaluation and monitoring of ovarian cancer, and also has been considered as an effective serum marker for many other types of cancer. However, its function in the process of sperm maturation is not fully unknown. The maturation of sperm in epididymis is characterized by the acquisition of motility and fertilization. As a member of the whey acid protein (WAP) family, several studies proposed the importance of HE4 in the maturity of sperm in epididymis. This article reviews the effect of HE4 on spermatozoa maturation in epididymis, which provides basis for the evaluation of male reproductive ability, early detection, early diagnosis and pathogenesis of male infertility.

PURPOSE: The most popular surgical approach to manage Lisfranc fracture-dislocations is the double-incision approach, which frequently causes a variety of complications, such as skin necrosis, rotational malreduction of the first tarsometatarsal joint (TMTJ) and lateral column dorsoplantar malreduction of the TMTJ. We introduce a three-incision approach to treat Lisfranc fracture-dislocations with only minor postoperative complications and good foot function. METHODS: We prospectively selected 30 previously healthy patients, ranging from 18 to 60 years of age, but only 23 patients completed the follow-up and thus were finally included, with an average age of 38.1 ± 12.9 years. All patients have sustained Lisfranc fracture-dislocations involving all three-column; 13.0% (3/23) were Myerson classification type A (medial), 47.8% (11/23) were type A (lateral), and 39.1% (9/23) were type C2. All patients were treated via a three-incision approach: a long incision made along the lateral border of the second ray was used as a working incision to visualize and reduce the first three TMTJs, as well as to apply internal fixation instrumentation; a 2 cm medial incision was made at the medial side of the first TMTJ as an inspecting incision, ensuring good reduction of the first TMTJ in medial and plantar view; another 1 cm inspecting incision was made at the dorsal side of the fourth/fifth TMTJ to prevent sagittal subluxation of the lateral column. Mean ± SD was used for quantitative data such as operation time, follow-up time and foot function scores. Postoperative complications were documented, and foot function was evaluated using the American orthopaedic foot & ankle society score, foot function index and Maryland foot score at follow-up. The foot function of the injured foot and contralateral foot of the same patient was at the end of follow-up, and independent sample t-test was used for statistical analysis. RESULTS: The median operation time was 117.9 ± 14.6 min (range 93 - 142 min). All complications occurred within three months after the operation, and included delayed wound healing (17.4%), superficial infection (8.7%), complex regional pain syndrome (4.3%) and neuroma (4.3%). There was no case of postoperative skin necrosis or malreduction. At the end of follow-up of 14.1 ± 1.2 months (range 12-16 months), the median American orthopaedic foot & ankle society score of the operated foot was 89.7 ± 5.7, the median foot function index was 21.7 ± 9.9, and the median Maryland foot score was 88.7 ± 4.8. There were no significant differences between the operated and contralateral sides, in terms of foot function, at the end of followup (p > 0.05). CONCLUSION The three-incision approach can provide adequate visualization of all TMTJs to ensure anatomical reduction and offer sufficient working space to apply internal fixation instrumentation, which is effective in treating three-column Lisfranc fracture-dislocations with minor soft tissue complications and satisfactory functional recovery.

OBJECTIVE: To explore the correlation between different body mass index (BMI) and prognosis of mantle cell lymphoma (MCL). METHODS: The clinical characteristics and biological indices of 108 patients with MCL treated in Fujian Medical University Union Hospital were retrospectively analyzed, and the effects of different BMI on overall survival (OS) and progression-free survival (PFS) were analyzed. The correlation between BMI and B symptoms, LDH and Ki-67 was further observed. Furthermore，the differences of BMI between Autologous peripheral blood stem cell transplantation(Auto-PBSCT) and conventional chemotherapy groups were explored. RESULTS: Among 108 patients, the median age at diagnosis was 59（25-79） years old, and the male to female ratio was 4.4∶1. 88.89% of patients with Ann Arbor staging III-IV, 63.89% with bone marrow involvement, and 49.07% with splenic infiltration. Patients with BMI ≥ 24 kg/m² were divided into two groups: the high BMI group and the low BMI group. The 5-year PFS and OS of patients in the low BMI group were 31.9% and 47.0%, respectively, while those in the high BMI group were 64.6% and 68.7%, respectively. The incidence of death in the high BMI group was lower than that of the low BMI group (P＜0.01). In multivariate analysis, BMI was an independent predictor of PFS (HR=0.282; 95% CI: 0.122-0.651; P=0.003) and an independent predictor of OS (HR=0.299; 95% CI: 0.129-0.693; P=0.005). Also, patients with B symptoms had a lower BMI than those without B symptoms (P=0.01), but BMI had no effect on patients' LDH and Ki-67. The prognosis of 16 patients treated with Auto-PBSCT was significantly better than that of the conventional chemotherapy group. There was no significant difference in BMI between Auto-PBSCT group and conventional chemotherapy group. CONCLUSION BMI is an independent prognostic factor for PFS and OS in MCL, and may be influenced by the effect of B symptoms on BMI.

The present study explored the effective approaches to realize the leading role of traditional Chinese medicine （TCM） in preventing diseases， the synergistic role in treating serious diseases， the core role in the rehabilitation of diseases and summarized the experience to provide feasible plans for the evaluation of other dominant diseases of TCM. To evaluate the effectiveness， safety， and economy of TCM in the treatment of ischemic stroke， encephalopathy project team of the China Center for Evidence-based Traditional Chinese Medicine（CCEBTCM） established an evaluation group to determine the work plan and complete the evaluation work. The concepts of the evaluation involved high-quality evidence， expert opinion survey， expert interview， and drug catalog. Under the guidance of clinical experts and methodologists， the evaluation work was completed in accordance with four steps， i.e.， plan making， data collection and data extraction， evidence synthesis and evaluation， and report writing with the rapid review method. Through the review of TCM and western medicine experts， the advantage of TCM in the treatment of ischemic stroke was positioned in the convalescence period with the predominant effects of improving the neurological function defect and improving the daily living ability. In the convalescence period of stroke， TCM treatment could improve post-stroke motor dysfunction， post-stroke cognitive impairment， consciousness disorder， swallowing disorder， aphasia， constipation， urinary function， diplopia， etc.， and the advantages of acupuncture， Chinese medicine， and traditional exercise were more prominent. In terms of safety， TCM treatment of ischemic stroke showed lower incidence of adverse reactions， fewer adverse events， and a milder degree of related symptoms. In terms of economic performance， the combined treatment of TCM and western medicine played a synergistic role and made the treatment cost more reasonable. Compared with conventional intervention， the integrated TCM and western medicine rehabilitation program showed more economic and social benefits.
