OBJECTIVE: To evaluate the efficacy of shockwave therapy, acupuncture, hyperthermia, biofeedback therapy, electrical nerve stimulation, magnetotherapy and ultrasound therapy in the treatment of chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS), and to provide evidence-based support for clinical decision-making. METHODS: Two researchers independently searched PubMed, Web of Science, Embase, Cochrane Library, CNKI, Wanfang, VIP and Chinese Biomedical Literature databases for randomized controlled trials(RCTs) on the effects of different interventions on CP/CPPS from the establishment of the databases to August 2024. We evaluated the quality of the included literature and extracted the relevant data according to the Cochrane Handbook for Systematic Reviews of Interventions, followed by network meta-analysis using Revman 5.3, R 4.33 and Stata17 software. RESULTS: A total of 25 RCTs involving 1 794 cases were included. The results of network meta-analysis showed that electrical nerve stimulation, shockwave therapy, biofeedback therapy, magnetotherapy, ultrasound therapy and acupuncture were significantly superior to conventional medication and placebo in the total NIH-CPSI scores(P< 0.05), and so were electrical nerve stimulation and shockwave therapy to acupuncture and hyperthermia(P< 0.05), magnetic therapy to hyperthermia, and ultrasound therapy to placebo(P< 0.05). Shockwave therapy, biofeedback therapy, electrical nerve stimulation, magnetotherapy and ultrasound therapy achieved remarkably better clinical efficacy than conventional medication and placebo in the treatment of CP/CPPS, and so did shockwave therapy than electrical nerve stimulation, hyperthermia, ultrasonic therapy, magnetotherapy and acupuncture. CONCLUSION For the treatment of CP/CPPS, electrical nerve stimulation is advantageous over the other interventions in improving total NIH-CPSI scores, and shockwave therapy is advantageous in relieving pain symptoms and clinical efficacy. This conclusion, however, needs to be further verified by more high-quality clinical studies.

BACKGROUND: The atherogenic index of plasma (AIP) has been shown to be positively correlated with cardiovascular disease in previous studies. However, it is unclear whether elderly people with long-term high AIP levels are more likely to develop coronary heart disease (CHD). Therefore, the aim of this study was to investigate the relationship between AIP trajectory and CHD incidence in elderly people. METHODS: 19,194 participants aged ≥ 60 years who had three AIP measurements between 2018 and 2020 were included in this study. AIP was defined as log₁₀ (triglyceride/high-density lipoprotein cholesterol). The group-based trajectory model was used to identify different trajectory patterns of AIP from 2018 to 2020. Cox proportional hazards models were used to estimate the hazard ratio (HR) with 95% CI of CHD events between different trajectory groups from 2020 to 2023. RESULTS: Three different trajectory patterns were identified through group-based trajectory model: the low-level group (n = 7410, mean AIP: -0.25 to -0.17), the medium-level group (n = 9981, mean AIP: 0.02-0.08), and the high-level group (n = 1803, mean AIP: 0.38-0.42). During a mean follow-up of 2.65 years, a total of 1391 participants developed CHD. After adjusting for potential confounders, compared with the participants in the low-level group, the HR with 95% CI of the medium-level group and the high-level group were estimated to be 1.24 (1.10-1.40) and 1.43 (1.19-1.73), respectively. These findings remained consistent in subgroup analyses and sensitivity analyses. CONCLUSIONS There was a significant correlation between persistent high AIP level and increased CHD risk in the elderly. This suggests that monitoring the long-term changes in AIP is helpful to identify individuals at high CHD risk in elderly people.

OBJECTIVE: To explore the therapeutic effects and underlying mechanisms of Dendrobium officinale (Tiepi Shihu) extract (DOE) on insomnia. METHODS: Forty-two male Sprague-Dawley rats were randomly divided into 6 groups (n=7 per group): normal control, model control, melatonin (MT, 40 mg/kg), and 3-dose DOE (0.25, 0.50, and 1.00 g/kg) groups. Rats were raised in a strong-light (10,000 LUX) and -noise (>80 db) environment (12 h/d) for 16 weeks to induce insomnia, and from week 10 to week 16, MT and DOE were correspondingly administered to rats. The behavior tests including sodium pentobarbital-induced sleep experiment, sucrose preference test, and autonomous activity test were used to evaluate changes in sleep and emotions of rats. The metabolic-related indicators such as blood pressure, blood viscosity, blood glucose, and uric acid in rats were measured. The pathological changes in the cornu ammonis 1 (CA1) region of rat brain were evaluated using hematoxylin and eosin staining and Nissl staining. Additionally, the sleep-related factors gamma-aminobutyric acid (GABA), glutamate (GA), 5-hydroxytryptamine (5-HT), and interleukin-6 (IL-6) were measured using enzyme linked immunosorbent assay. Finally, we screened potential sleep-improving receptors of DOE using polymerase chain reaction (PCR) array and validated the results with quantitative PCR and immunohistochemistry. RESULTS: DOE significantly improved rats' sleep and mood, increased the sodium pentobarbital-induced sleep time and sucrose preference index, and reduced autonomic activity times (P<0.05 or P<0.01). DOE also had a good effect on metabolic abnormalities, significantly reducing triglyceride, blood glucose, blood pressure, and blood viscosity indicators (P<0.05 or P<0.01). DOE significantly increased the GABA content in hippocampus and reduced the GA/GABA ratio and IL-6 level (P<0.05 or P<0.01). In addition, DOE improved the pathological changes such as the disorder of cell arrangement in the hippocampus and the decrease of Nissel bodies. Seven differential genes were screened by PCR array, and the GABA_A receptors (Gabra5, Gabra6, Gabrq) were selected for verification. The results showed that DOE could up-regulate their expressions (P<0.05 or P<0.01). CONCLUSION DOE demonstrated remarkable potential for improving insomnia, which may be through regulating GABA_A receptors expressions and GA/GABA ratio.

Aim To explore the role of SIRT1/Nrf2 / HO-1 in alleviating the cognitive function impairment by sevoflurane treatment in a mouse model of postoperative cerebral reperfusion. Methods C57BL/6J mice were randomly divided into five groups: sham operation group, hemorrhagic shock reperfusion group, sevoflurane postconditioning group, sevoflurane postcondition-ing + SIRT1 inhibitor group and sevoflurane postconditioning + Nrf2 inhibitor group. Mice were subjected to Morris water maze test after cerebral ischemia reperfusion. The ATP, superoxide dismutase (SOD), ROS and MDA contents in tissue of mice were detected. SIRT1, Nrf2 and HO-1 proteins in tissue were detected by Western blot. Results After hemorrhagic shock, the learning and memory ability of mice was reduced.ATP and SOD concentration in hippocampus was reduced , MDA and ROS concentration increased, and the SIRT, Nrf2 and HO-1 concentration was reduced. Sevoflurane improved the cognitive dysfunction and oxi-dative damage in postoperative mice, and the neuro-protective effect of sevoflurane on hemorrhagic shock and resuscitation mice was weakened followed with SIRT1 and Nrf2 inhibitors. Conclusion Sevoflurane probably alleviates the oxidative reaction damage and cognitive impairment caused by cerebral reperfusion in mice through SIRT1/Nrf2/H0-1 pathway.

ObjectiveTo investigate the effect and possible mechanism of Sishenwan in ameliorating visceral sensitivity in the rat model of diarrhea-predominant irritable bowel syndrome （IBS-D） due to spleen-kidney Yang deficiency. MethodForty male SPF-grade rats were randomly assigned into five groups： blank control， model， low- （3.51 g·kg^-1） and high-dose （7.02 g·kg^-1） Sishenwan， and Peifikang （0.54 g·kg^-1） groups. Except the blank control group， the other groups underwent maternal separation stress and Sennae Folium decoction gavage for the modeling of IBS-D due to spleen-kidney Yang deficiency. After corresponding drug interventions， the general conditions of the rats were observed， and the number of defecation pellets within 6 h and the minimum threshold of abdominal withdrawal reflex （AWR） were measured. Enzyme-linked immunosorbent assay （ELISA） was used to measure the serum levels of tumor necrosis factor （TNF）-α， gastrin （GAS）， corticosterone （CORT）， and adrenocorticotropic hormone （ACTH）. Hematoxylin-eosin （HE） staining was employed to observe pathological changes in the colon tissue. Toluidine blue staining was used to assess mast cell degranulation in the colon tissue. Western blot was performed to determine the protein levels of p38 mitogen-activated protein kinase （MAPK）， c-Jun N-terminal kinase （JNK）， transient receptor potential vanilloid 1 （TRPV1）， and protease-activated receptor 2 （PAR2） in the colon tissue. Immunohistochemistry was employed to measure the protein level of TRPV1 in the colon tissue， and immunofluorescence was used to detect the positive expression of substance P （SP） and calcitonin gene-related peptide （CGRP） in the colon tissue. ResultCompared with the blank control group， the model group showed increased number of defecation pellets within 6 h （P<0.01）， decreased minimum threshold of AWR （P<0.01）， elevated serum TNF-α level （P<0.01）， lowered levels of GAS， CORT， and ACTH （P<0.05， P<0.01）， increased mast cell degranulation rate （P<0.01）， increased positive expression of TRPV1， SP， and CGRP （P<0.05， P<0.01）， and upregulated protein levels of p38 MAPK， JNK， TRPV1， and PAR2 （P<0.01）. Compared with the model group， the high-dose Sishenwan group showed increased minimum threshold of AWR （P<0.01）， reduced defecation frequency in both the high-dose Sishenwan and Peifikang groups （P<0.05， P<0.01）， lowered TNF-α level （P<0.05， P<0.01）， elevated levels of GAS， CORT， and ACTH （P<0.05， P<0.01）， decreased mast cell degranulation rate （P<0.01）， reduced positive expression of TRPV1， SP， and CGRP （P<0.05， P<0.01）， and downregulated protein levels of p38 MAPK， JNK， TRPV1， and PAR2 （P<0.05， P<0.01）. ConclusionSishenwan can ameliorate visceral sensitivity in the rat model of diarrhea-predominant irritable bowel syndrome due to spleen-kidney Yang deficiency by regulating the p38 MAPK/JNK/TRPV1 signaling pathway.

Celastrol and wilforlide A are the main active triterpenoids of the traditional Chinese medicine Lei Gong Teng, which have anti-tumour, anti-inflammatory and immunosuppressive activities, and are the material basis for the clinical efficacy of Lei Gong Teng-related Chinese medicinal preparations. By analysing the biosynthetic pathway of active ingredients, optimizing genetic elements and utilizing "cell factory" to produce triterpenoids heterologously will be an effective way to obtain from Tripterygium wilfordii in the future in a "low-cost and high-efficient" manner. CYP712Ks are the first cytochrome P450s involved in the skeleton modification of friedelane-type and oleanane-type triterpenoids in T. wilfordii, and they can catalyse the generation of polpunonic acid from friedelin and 3-epi-katonic acid from β-amyrin by carboxylation at C-29 position. In this study, four multifunctional TwCYP712K1/2/3/5 were used to clarify the catalytic function and substrate selection preference using in vivo functional characterization in Saccharomyces cerevisiae. The spatial structure of the protein-substrate binding was clarified through homology modeling and molecular docking, and then the differential amino acids in the active pocket of the protein were mutated to clarify the crucial amino acids determining the catalytic function and the selection of substrate structure. A total of 63 mutant elements were constructed, and the amino acid sites affecting the carboxylation function of TwCYP712Ks were analyzed. In particular, the key amino acids affecting the substrate selectivity of TwCYP712K2 towards oleanane-type and friedelane-type triterpenoids were revealed and the TwCYP712K2^F127I and TwCYP712K2^A227T mutants would result in a reversal of the product ratio. In conclusion, four proteins of TwCYP712Ks were semi-rationally designed by homologous protein alignment and mutual mutation to elucidate multiple amino acid sites determining the catalytic function of the proteins, and a series of activity-enhancing or altering mutants were obtained, which provide abundant catalytic elements for the biosynthesis of active triterpenoids from T. wilfordii, and the mechanism of carboxylation in the C-29 position was initially elucidated.

Objective To evaluate the application value of artificial intelligence mixed reality(AI-MR)technology in the planning of ultrasound-guided percutaneous nephrolithotomy(PCNL)for special types of complex upper urinary stones.Methods The prospective single-center,single-arm clinical study involved 15 patients with complex upper urinary stones undergoing ultrasound-guided PCNL during Aug.2022 and May 2023,including 9 male and 6 female,3 cases of pelvic ectopic kidney stones,5 cases of horseshoe kidney stones,3 cases of renal stones combined with spinal deformity,and 4 cases of transplant kidney stones.Based on preoperative computed tomography urography(CTU)data,digital three-dimensional reconstruction was performed,and AI-MR was used to project surgery-related three-dimensional images in real space to obtain"perspective"information of the surgical area.This facilitated preoperative design and planning,including target calyx,number of channels,and auxiliary measures.The compliance of target calyx and number of channels,stone clearance rate,total operation time,time required to establish the percutaneous renal channel,decrease in hemoglobin level,surgical complications,and postoperative hospital stay were analyzed.Results All 15 patients underwent preoperative planning using AI-MR and successfully completed one-stage ultrasound-guided PCNL.Based on the preoperative planning,we utilized S-PCNL alone or combined with Needle-perc or antegrade/retrograde FURS/RIRS.Among all patients,4 underwent single-channel S-PCNL,3 multi-channel S-PCNL,and 8 S-PCNL combined with Needle-perc or FURS.The compliance of target calyx and number of channels was 86.7％,the one-stage stone clearance rate was 80.0％,the average time for establishing the channel was(2.3±0.3)minutes,the average total operation time was(61.5±12.2)minutes,the mean decrease in hemoglobin level was(9.6±1.2)g/L,and the average postoperative hospital stay was(4.6±0.5)days.There were no Clavien-Dindo grade ≥ Ⅱ complications,such as blood transfusion,organ injury,or urosepsis.Conclusion Before surgery,AI-MR can be used to quantitatively analyze imaging data for patients with special types of complex upper urinary stones,which can achieve three-dimensional fluoroscopy effects,formulate surgical plans,optimize puncture paths,effectively avoid the risk of damage to surrounding organs,reduce complications,shorten treatment cycle and improve the first-stage stone clearance rate.
