Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

Objective To clarify the changes in CXCL5 in serum and gastric tissues of patients with chronic atrophic gastritis(CAG)and precancerous lesions of gastric cancer(PLGC)and to investigate the predictive value of CXCL5 for the diagnosis of CAG and PLGC.Methods This study enrolled 72 participants of CAG admitted to the Department of Splenology and Gastroenterology of the Second Affiliated Hospital of Anhui University of Chinese Medicine from June 2022 to June 2023,with gastroscopy and pathologically confirmed diagnosis,as well as 68 healthy participants who underwent gastroscopy in the same period at our department.We collected clinical information and laboratory results from all participants.The logistic regression analysis methods were used to identify the diagnostic value of serum CXCL5.Furthermore,in order to clarify the role of CXCL5 in the developent of CAG,a total of 15 patients each with CAG,intestinal metaplasia,and dysplasia treated at our hospital from June 2023 to December 2023,and 15 healthy participants were selected.The relationship between the expression of CXCL5 and the degree of clinicopathology was analysed in each group using ELISA,PCR,and immunohistochemistry staining to validate and assess the diagnostic efficacy of CXCL5.Results The study found that several factors were associated with CAG,including family history of tumours,smoking and alcohol consumption history,dietary regularity,Helicobacter pylori infection,the number of lesions,gastric function scores and CXCL5(P<0.05).The ROC curve had an AUC of 1.00 and a Youden index of 0.986,indicating excellent predictive ability.The ELISA results indicated a significantly higher serum CXCL5 expression level in the CAG,intestinal metaplasia,and dysplasia groups compared to the normal group.There was a positive correlation between the serum CXCL5 expression level and the degree of pathology.The PCR and immunohistochemistry staining results indicate that the mRNA and pro-tein expression levels of CXCL5 in gastric tissues of patient groups were significantly higher compared to the nor-mal group.Furthermore,the mRNA and protein expression levels of CXCL5 in gastric tissues were positively correlated with the degree of pathology.Conclusions The results indicate that CXCL5 is highly expressed in the serum and gastric tissues of patients with CAG and PLGC,and its expression level is positively correlated with the degree of pathology.Therefore,CXCL5 could serve as a predictive indicator and a potential therapeutic target for the diagnosis of CAG and PLGC.

OBJECTIVE: To explore clinical effect of arthroscopy-assisted rotator cuff tendon transfer in treating irreparable rotator cuff tears (IRCT). METHODS: From May 2015 to May 2018, 23 patients with unrepairable rotator cuff tears were treated with arthroscopy-assisted rotator cuff tendon transfer, and 21 patients were followed up finally, including 8 males and 13 females, aged from 48 to 82 years old with an average of(64.3±9.1) years old;the courses of disease ranged from 6 to 36 months with an average of (14.0±6.4) months. American Rotator and Elbow Surgeons Score(ASES) and Constant-Murley score were used to evaluate clinical efficacy before surgery and at the latest follow-up. RESULTS: All 21 patients were followed up for 36 to 54 months with an average of (39.4±4.4) months. Axillary incision of 1 patient was redness, swelling and exudation after surgery, which healed after 3 weeks of dressing change, and exudate culture was negative. At the latest follow-up, MRI showed partial tearing of the metastatic tendon in 2 patients, but pain and movement of the affected shoulder were still better than before surgery. ASES increased from preoperative (41.0±9.6) scores to the latest follow-up (75.6±14.0) scores, and had statistical difference (t=10.50, P<0.01). Constant-Murley score increased from (49.8±7.1) scores before operation to (67.5±11.6) scores at the latest follow-up (t=11.27, P<0.01). CONCLUSION Arthroscopic assisted latissimus dorsalis tendon transposition restores physiological and anatomical structure of glenohumeral joint by reconstructing balance of horizontal and vertical couples of shoulder joint, thus achieving the stability of the shoulder joint, relieving shoulder pain and improving shoulder joint function.

OBJECTIVETo evaluate the efficacy and safety of Heyan Kuntai Capsule (, HYKT) and hormone therapy (HT) on perimenopausal syndromes (PMSs).

METHODSFrom 2005 to 2008, 390 women with PMSs were recruited from 4 clinic centers. The inclusion criteria included ages 40 to 60 years, estradiol (E2) below 30 ng/L, and follicle stimulating hormone (FSH) above 40 IU/L, etc. The patients were randomly assigned to HYKT group or HT group by random number table method, administrated HYKT or conjugated estrogen with/without medroxyprogesterone acetate tablets for 12 months. During treatment, the patients were interviewed quarterly, Kupperman Menopausal Index (KMI) scores, hot flush scores, insomnia scores, Menopause-Specific Quality of Life (MENQOL) scores and adverse effects were used for evaluating drug efficacy and safety respectively. The last interview was made at the end of 12-month treatment RESULTS: After treatment, KMI scores of HYKT group and HT group were both significantly decreased compared with baseline (P <0.01) and there was no significant difference between groups (P >0.05), except that KMI of HYKT group was higher after 3-month treatment (P <0.05). After treatment, hot flush and insomnia scores were both improved significantly in two groups (P <0.01); and HT had a better performance than HYKT in improving hot flush (P <0.05). MENQOL were significantly improved in both groups after treatment (P <0.01); but there was no significant difference between two groups (P >0.05). The incidence of adverse event in the HYKT group was much lower than that in the HT group (P <0.01).

CONCLUSIONSHYKT could effectively relieve PMSs and improve patients quality of life without severe adverse reactions. Although HYKT exerted curative effects more slowly than hormone, it possessed better safety profile than hormone.

Protein palmitoylation, one of post-translation modifications, refers to the addition of saturated 16-carbon palmitic acid to cysteine residues via the thioester bond. It plays key roles in various functional activities, such as the interaction, stability and location of proteins. Heat shock protein 90 (Hsp90), an important molecular chaperone, has been reported to be involved in sperm capacitation. However, it remains unclear whether protein palmitoylation exists in sperm and whether Hsp90 in sperm is palmitoylated under different physiological conditions. In this study, we examined whether the protein palmitoylation is present in mouse cauda epididymis sperm using acyl-biotin exchange method, predicted the potential palmitoylated sites of Hsp90 by the software CSS-Palm 4.0 and detected the palmitoylated Hsp90 in the mouse sperm from caput epididymis and cauda epididymis by immunoprecipitation. We found that some proteins, approximately 50, 65, 72, 85 and 130 kDa, were palmitoylated in mouse cauda epididymis sperm. Five sites in two Hsp90 isoforms were predicted to be palmitoylated. The results also showed that Hsp90 in mouse sperm was palmitoylated and its palmitoylation level was involved in different physiological conditions: the palmitoylation level of cauda epididymis sperm was higher than that of caput epididymis sperm; and the palmitoylation level after capacitation was much higher than that before capacitation. In conclusion, this study reveals that protein palmitoylation is present in mouse sperm and the palmitoylated Hsp90 is associated with different physiological conditions in sperm.
