OBJECTIVE: To observe the clinical efficacy of electroacupuncture (EA) at "four points of sacral region" for mild-to-moderate benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). METHODS: A total of 58 patients with BPH/LUTS were randomly divided into a sacral four-point EA group (29 cases, 1 case dropped out) and a conventional EA group (29 cases, 1 case dropped out). EA was applied at bilateral points 0.5 cun lateral to the sacrococcygeal joint and Huiyang (BL35) in the sacral four-point EA group; and was applied at Guanyuan (CV4), Zhongji (CV3), Qugu (CV2) and bilateral Shuidao (ST28), Sanyinjiao (SP6), Zusanli (ST36) in the conventional EA group. Both groups received continuous wave, 2 Hz in frequency, 30 min a time, once every other day, 3 times a week for 4 weeks. Before treatment, after 2 and 4 weeks of treatment, and in follow-up of 1 month after treatment completion, the international prostate symptom score (IPSS), the overactive bladder symptom score (OABSS), the quality of life (QOL) score were observed; before and after treatment, the prostate volume (PV) was measured by abdominal ultrasound; and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: Compared before treatment, the scores of IPSS, OABSS and QOL were decreased after 4 weeks of treatment and in follow-up in both groups (P<0.01, P<0.05). In the sacral four-point EA group, the scores of IPSS and QOL after 4 weeks of treatment and in follow-up were lower than those in the conventional EA group (P<0.05, P<0.01), and the OABSS score in follow-up was lower than that in the conventional EA group (P<0.05). After 4 weeks of treatment and in follow-up, the reductions of IPSS and OABSS scores compared before treatment in the sacral four-point EA group were larger than those in the conventional EA group (P<0.01, P<0.05); After 2, 4 weeks of treatment and in follow-up, the reductions of QOL score compared before treatment in the sacral four-point EA group were larger than those in the conventional EA group (P<0.01). No significant difference in PV was observed after treatment between the two groups (P>0.05). The total effective rate was 75.0% (21/28) in the sacral four-point EA group, which was higher than 39.3% (11/28) in the conventional EA group (P<0.01). CONCLUSION EA at "four points of sacral region" can effectively improve the LUTS, overactive bladder symptom and quality of life in patients with mild-to-moderate BPH, and has good short-term and long-term efficacy, although it can not reduce prostate volume.

Sjögren's syndrome (SS) is an autoimmune disease characterized primarily by oral and periocular dryness. Astragalus-Salvia (AS) and Ophiopogon-Dendrobium (OD) represent two frequently utilized herb pairs in SS treatment. While the combination of AS-OD herb pairs demonstrates clinical efficacy in alleviating SS symptoms, its underlying mechanism remains unclear. This investigation sought to assess the therapeutic effects and elucidate the potential mechanisms of AS-OD in non-obese diabetic (NOD)/Ltj mice with SS. The study utilized NOD/Ltj mice as SS models, administering AS-OD treatment for 10 weeks at doses of 113.1, 226.2, and 339.3 mg·d^-1·20 g^-1. Results demonstrated that AS-OD improved SS symptoms, evidenced by enhanced salivary flow rate, decreased anti-SSA/Ro and anti-SSB/La antibody levels, increased swimming duration, and reduced lactate (LA) and blood urea nitrogen (BUN) levels in NOD/Ltj mice. AS-OD reduced lymphocyte infiltration, enhanced Aquaporin-5 (AQP5) expression in the submandibular gland, decreased inflammatory cytokine levels in the submandibular gland, and reduced the T helper type 17/regulatory T lymphocyte (Th17/Treg) cell ratio in the spleen. Transcriptomic and proteomic analyses indicated AS-OD's involvement in regulating phosphatidylinositol-3-kinase/protein kinase B (PI3K/AKT) and Janus kinase 3/signal transducer and activator of transcription 3 (JAK1/STAT3) pathways, with inhibitory effects validated in both NOD/Ltj mice submandibular gland and A-253 cells. Furthermore, AS-OD enhanced cell viability and reduced A-253 cell apoptosis through the PI3K/AKT pathway. In A-253 cells, AS-OD reduced inflammatory cytokine levels, CXC chemokine ligand 9/10 (CXCL9/10), and T-cell chemotaxis by inhibiting the JAK1/STAT3 pathway. AS-OD mitigates SS by suppressing inflammation and immune responses through the PI3K/AKT and JAK1/STAT3 pathways.

【Objective】 To explore the composition of culturable bacteria in platelets through bacterial culturomics and verify the results of culturomics and metagenomics to improve the detection rate of bacteria in platelets. 【Methods】 Platelet samples from 6 healthy people were collected. Eight kinds of culture media were placed in aerobic conditions and 12 kinds of culture media were placed in anaerobic conditions for large-scale culture and isolation of bacteria in platelets. The isolated single colony was identified by 16S rRNA gene sequencing. The bacterial abundance of healthy human platelet microbiome was analyzed by metagenomic sequencing, and the cultivable bacterial species in platelets was confirmed based on metagenomic and culturomics results. 【Results】 A total of 90 strains of bacteria belonging to 3 phylums, 5 classes, 5 orders, 7 families, 9 genus and 23 species were isolated from 6 platelet samples by culturomics. Among them, the strains with more monoclonal clones at the species level were Brevundimonas aurantiaca (16.7%), Bacillus sp. Y1 (15.6%), Cutibacterium acnes (14.4%) and Brevibacillus brevis (13.3%). The platelet samples sequenced by mNGS showed that the abundance values of Proteobacteria, Firmicutes and Actinobacteria were high. The bacteria detected by both culturomics and metagenomic sequencing methods were as follows: Firmicutes: Bacillus sp. Y1, B. thuringiensis, B. cereus, B. mobilis, B. velezensis, Staphylococcus epidermidis, and Brevibacillus brevis; Actinobacteria: Cutibacterium acnes; Proteobacteria: Escherichia coli and Delftia tsuruhatensis. 【Conclusion】 The mutual validation of culturomics and metagenomics has identified some bacteria, proving that bacteria exist in platelets.

Objective:To summarize the clinical manifestations and color Doppler ultrasonography of benign lymphoepithelial disease (BLL) in lacrimal gland, so as to improve the diagnostic accuracy of lacrimal BLL.Methods:Clinical manifestations and color Doppler flow imaging (CDFI) features of lacrimal BLL in 16 patients (2 males and 14 females, with 31 lesions) who visited the Second Hospital of Hebei Medical University from November 2014 to August 2019 were retrospectively analyzed.Results:The performance for lesions in patients with duration less than 3 months was scattered in irregular low echo, lesion blood flow signals within the rich (Adler Ⅱ level), pathologic examination results showed more lymphocytes were seen in the lacrimal matrix, and the myoepithelium of the lacrimal duct grew to form the epithelium-myocutaneous island. The ultrasonic feasures in patients with course of 3-6 months were in multiple categories such as circular low echo, "honeycomb" change, CDFI showed lesions with a lot of blood flow signals (Adler Ⅲ level), the pathological examination results indicated that there were a large number of lymphocytes and epithelial-musculocutaneous islands in the lacrimal matrix, and the lymphocytes were significantly increased compared with patients with the course of disease less than 3 months. The ultrasound results in patients with a course of more than 6 months showed lesions in multiple categories such as circular low echo, and large low echo, greater than 3 mm in diameter, CDFI showed lesions within the same large amounts of blood flow signals (Adler Ⅲ level), the pathological examination results were consistent with the course of 3 to 6 months. One patient had positive tuberculin test and 11 had higher IgG4 than normal.The number of lymphocytes increased with the prolongation of disease course.Conclusions:With the expert knowledge of color Doppler ultrasonographic characteristics of lacrimal gland BLL and with the serum IgG4 level helps to improve the accuracy of ultrasonic diagnosis.
