ObjectiveTo observe the clinical efficacy of tonifying kidney and replenishing essence on asthenozoospermia patients with the syndrome of kidney essence deficiency and the effects of this method on the adenosine 5′-monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin complex 1 (mTORC1) signaling pathway. MethodsSeventy-two eligible asthenozoospermia patients with the syndrome of kidney essence deficiency treated in the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from February 2023 to January 2024 were selected and randomly assigned into an observation group and a control group, with 36 patients in each group. The observation group received oral administration of Guilu Tianjing capsules, while the control group received oral administration of L-carnitine oral solution. The treatment course lasted for 4 weeks in both groups. The observed indicators included sperm progressive motility rate (PR), total sperm motility (PR+NP), percentage of normal mitochondrial membrane potential (MMP), and traditional Chinese medicine (TCM) symptom scores before and after treatment in both groups. A three-month follow-up was instituted to record the conception status of the patients’ spouses. Additionally, eight patients were randomly selected from the eligible patients in the observation group, and four healthy males with normal semen routine examination results were included as the control group for the determination of protein expression. Western blotting was conducted to assess the expression of AMPK, phosphorylated (p)-AMPK, regulatory-associated protein of mTOR (RAPTOR) and p-RAPTOR, and PTEN-induced putative kinase 1 (PINK1) in sperms from the observation group before and after treatment, as well as in the sperms of the control group. ResultsThe pregnancy rate of spouses in the observation group was 9.09% (3/33), which was higher than that (3.33%, 1/30) in the control group. The total response rate was 84.8% (28/33) in the observation group and 66.7% (20/30) in the control group, with no statistically significant difference. After treatment, both groups were improved considering PR, PR+NP, MMP, and TCM symptom scores (P<0.01). Moreover, the observation group exhibited more pronounced decreases in TCM symptom scores than the control group (P<0.05), while the changes in PR, PR+NP, and MMP showed no statistical significance between groups. Compared with the control group, the asthenozoospermia group exhibited upregulations in phosphorylation levels of AMPK and RAPTOR and protein level of PINK (P<0.01). The administration of Guilu Tianjing Capsules led to downregulations in the phosphorylation levels of AMPK and RAPTOR and protein level of PINK1 (P<0.01). However, the protein levels of AMPK and RAPTOR demonstrated no significant difference between before and after treatment. During the study period, neither group of patients exhibited any notable adverse reactions. ConclusionGuilu Tianjing capsules can enhance the sperm motility and percentage of normal mitochondrial membrane potential in asthenozoospermia patients with the syndrome of kidney essence deficiency by downregulating the AMPK/mTORC1 signaling pathway, lowering the protein level of PINK1, and inhibiting excessive activation of mitophagy.

Inflammatory bowel disease (IBD) is an autoimmune disorder involving complex immune regulation, where balancing localized and systemic immunosuppression is a key challenge. This study aimed to enhance the therapeutic efficacy by engineering the probiotic Escherichia coli Nissle 1917 (EcN). We removed endogenous plasmids pMUT1 and pMUT2 from wild-type EcN and expressed the mPD-L1 (19‒238 aa)-mFc fusion protein on the bacterial surface using a cytolysin A (ClyA) fragment. This modification stabilized mPD-L1 (19‒238 aa) protein expression and promoted its recruitment to outer membrane vesicles (OMVs). The engineered strain, EcNΔpMUT1/2-ClyA-mPD-L1-mFc (EcN-ePD-L1-mFc), features conditional ePD-L1-mFc expression under the araBAD promoter, enhancing gut-targeted release and reducing systemic side effects. This strain improved treatment targeting and efficiency by enabling direct ePD-L1-mFc interaction with immune cells at inflammation sites. OMVs from this strain induced Treg proliferation, inhibited effector T cell proliferation in vitro, and significantly improved intestinal inflammation and colonic epithelial barrier repair in vivo. Additionally, the bacterium restored intestinal microbiota balance, increasing Lactobacillaceae and reducing Bacteroides. This study highlights the engineered bacterium's potential for targeted intestinal immune modulation and offers a novel local IBD treatment approach with promising clinical prospects.

Living systematic review (LSR) is a systematic review methodology that incorporates regular updates to integrate new evidence, aiming to rapidly reflect the latest research findings. Although LSRs are increasingly adopted in clinical fields, their reporting quality remains inconsistent and lack of standardized guidelines. To standardize LSR reporting, the PRISMA 2020 statement has released an extension checklist (PRISMA-LSR). This paper describes the background of PRISMA-LSR release and main revisions, and interprets it with examples, with the goal of guiding future LSR research and enhancing reporting quality.

Objective:To evaluate the clinical efficacy and impact on quality of life of the biofeedback (BF) therapy combined with the Wenyang Yiqi Prescription and self-efficacy interventions in patients with functional defecation disorders (FDD).Methods:A prospective, randomized controlled trial design was employed. A total of 128 FDD patients were selected from the Pelvic Floor Center of the Department of Proctology, Suzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine, between January 2021 and April 2023. These patients were randomly divided into two groups, with 64 cases in each group. Additionally, 41 historical control patients, who had received conventional BF training between June 2015 and January 2018 at the same center, were included for comparison. The historical control group received conventional BF therapy, the intervention group 1 combined BF therapy with self-efficacy interventions, and the intervention group 2 added the Wenyang Yiqi Prescription based on intervention group 1's treatment. All three groups underwent two treatment courses. Constipation symptom scores before and after treatment were performed; self-efficacy was assessed via the Self-Rated Abilities for Health Practices scale (SRAHP); health behaviors were evaluated using the Health-Promoting Lifestyle Profile (HPLP); anxiety and depression were evaluated through Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS); quality of life was measured through SF-36. Clinical efficacy was evaluated based on constipation symptom scores.Results:During the treatment period, seven patients dropped out due to personal reasons, leaving 61 patients in intervention group 1 and 60 patients in intervention group 2 for efficacy analysis. The total effective rates were 80.32% (49/61) in intervention group 1, 83.33% (50/60) in intervention group 2, and 56.10% (23/41) in the historical control group. The total effective rates of both intervention groups were significantly higher than those in the historical control group ( χ2=7.06, 9.15; P=0.029, 0.010, respectively). After treatment, intervention group 2 showed significantly lower constipation-related straining scores [1 (1, 2) vs. 2 (1, 2), Z=-4.51] compared to intervention group 1 ( P<0.05). Additionally, intervention group 2 had lower scores for straining [1 (1, 2) vs. 2 (1, 2), Z=-3.15] and defecation time [1 (0, 1) vs. 1 (1, 2), Z=-3.13] compared to the historical control group ( P<0.05). Psychological comfort efficacy (19.13 ± 2.51 vs. 16.98 ± 1.86, t=5.36), health responsibility efficacy (23.63 ± 4.69 vs. 22.59 ± 3.05, t=2.06), and overall SRAHP scores (75.98 ± 4.44 vs. 72.33 ± 5.16, t=4.17) were higher in intervention group 2 compared to intervention group 1 ( P<0.05). The HPLP scores (79.33 ± 11.13 vs. 72.80 ± 9.20, t=3.10) of intervention group 2 were higher than those of the historical control group ( P<0.05). Emotional functioning scores (75.98 ± 18.45 vs. 68.92 ± 20.58 and 68.55 ± 18.21, F=20.91) in intervention group 2 were higher than in both intervention group 1 and the historical control group ( P<0.05). Conclusion:The combination of the Wenyang Yiqi Prescription with BF therapy and self-efficacy interventions effectively improves the clinical symptoms and quality of life in FDD patients.

Objective:
To estimate the epidemic threshold and graded intensity thresholds of influenza in Zhejiang Province from 2012 to 2023 using the moving epidemic method (MEM), and evaluate the intensity of influenza epidemics, so as to provide the reference for influenza prevention and control in Zhejiang Province.
Methods:
The positive rates of influenza virus per week during the influenza epidemic seasons (from 40th week to 20th week of the following year) in Zhejiang Province from 2012 to 2022 were collected through the Chinese Influenza Surveillance Information System. A MEM model was established and optimized using cross-validation. The maximum accumulated rates percentage was used to divide the epidemic into pre-epidemic, epidemic, and post-epidemic periods, and to estimate the epidemic thresholds and graded intensity thresholds. The intensity of influenza epidemics in Zhejiang Province during the 2022-2023 epidemic season were assessed.
Results:
The positive rates of influenza virus in five epidemic seasons from 2012 to 2022 were included in the model. The MEM model performed best when the parameter δ was set to 1.5, with a sensitivity of 0.971, a specificity of 0.745, and a Youden's index of 0.716. According to the model analysis, the epidemic beginning and ending thresholds of influenza in Zhejiang Province during the 2022-2023 epidemic season were 19.32% and 10.92%, respectively, and the medium, high, and extremely high intensity thresholds were 48.65%, 63.49%, and 68.47%, respectively. During 2022-2023, the influenza epidemic was in the pre-epidemic period from the 40th week in 2022 to the 7th week in 2023; the epidemic period was from the 8th to the 18th week, the epidemic intensity was low in the 8th week and increased to a high level in the 9th week, and reached to a extremely high level from the 10th to the 13th week, then fell to the high and the medium level in the 14th week and 15th week, respectively, and fell to a low level from the 16th to the 18th week; the influenza epidemic entered the post-epidemic period since the 19th week.
Conclusion
MEM could be applied for evaluation of influenza epidemic intensity, providing the reference for early identification and taking graded preventive and control measures.

OBJECTIVE
To establish the quality standard of Triadica cochinchinensis and to perform the acute toxicity study.
METHODS
Appearance properties, powder microscopic identification, and thin-layer chromatography(TLC) identification were researched. The specific chromatogram was established by HPLC. The content of cadmium(Cd), lead(Pb), arsenic(As), copper(Cu), and mercury(Hg) was determined by inductively coupled plasma-mass spectrometry(ICP-MS). Acute toxicity was studied by maximum dose.
RESULTS
The outer skin of herbs was dark brown, and the inner surface was light yellow brown and fibrous. Besides, crystal sheath fiber was common, and calcium oxalate clusters arranges in rows. In the TLC diagram of the test product, the fluorescent spots of the same color were displayed at the corresponding position of the control product(scopoletin, isofraxidin). Five common peaks were calibrated in the characteristic map and the three characteristic peaks(scopoletin, isofraxidin, dimethylfraxetin) were recognized. The content of the measured heavy metal elements was lower than the national limit standard. The linear correlation coefficient was R2 > 0.999. The precision, stability, repetitive RSD were < 10%. The average recovery rate of the added sample was 80%−120%, and the RSD was < 10%. The maximum dose of the acute toxicity test was 184.09 g·kg−1. The 14 d internal body mass, food intake, organ-body ratios, the serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, blood urea nitrogen, and creatinine were not significantly different by comparing with the normal controls. Therefore, no significant toxicity was observed.
CONCLUSION
The established standard can provide a reference for evaluating the quality of Triadica cochinchinensis. The heavy metal content of ten batches of medicinal materials is within the safe range. Acute toxicity test show that there is no obvious significant adverse teactions after oral administration, and the safe dose range is large, which can provide a reference for the subsequent development and utilization.
