OBJECTIVE To evaluate the efficacy and safety of total glucosides of paeonia (TGP) in the treatment of systemic lupus erythematosus (SLE). METHODS Randomized controlled trial (RCT) about TGP combined with western medicine versus western medicine alone for SLE treatment were retrieved from PubMed, Embase, Cochrane Library, Web of Science, CNKI, VIP, Wanfang Data, and CBM. The search period spanned from the inception of each database to June 1, 2025. After literature screening, data extraction, and quality assessment of the included studies, Meta-analysis was performed using RevMan 5.4 software. RESULTS Fifteen RCTs, involving 1 318 patients, were included. Meta-analysis results showed that compared with western medicine alone, TGP combined with western medicine significantly improved clinical efficacy [OR=4.96, 95%CI(3.41, 7.23), P<0.000 01], complement 3 [MD=0.18, 95%CI (0.13, 0.23), P<0.000 01] and complement 4[MD=0.08, 般021) 95%CI (0.04, 0.11), P<0.000 01], and reduced the levels of immunoglobulin G (IgG) [MD=-3.10, 95%CI (-3.59,-2.62), P<0.000 01], IgA [MD=-0.68, 95%CI (-0.78, -0.58), P<0.000 01], IgM [MD=-0.43, 95%CI (-0.53,-0.34), P<0.000 01], systemic lupus erythematosus disease activity index (SLEDAI) [MD=-1.59, 95%CI (-2.20, -0.99), P<0.000 01], recurrence rate [OR=0.23, 95%CI (0.13, 0.42), P<0.000 01] and the incidence of adverse drug reactions [OR= 0.54, 95%CI (0.36, 0.82), P=0.004]. CONCLUSIONS TGP therapy can improve clinical efficacy of SLE patients, promote the restoration of immunoglobulins and complements, reduce SLEDAI and recurrence rate and has good safety.

ObjectiveTo explore the possible mechanism of Tongbian Decoction (通便汤, TD) in treating slow transit constipation (STC). MethodsTwenty-four SD rats were randomly divided into normal group, model group, TD group, and mosapride group, with 6 rats per group. Except for the normal group, STC models were established by intragastric administration of loperamide hydrochloride combined with normal saline. On the day following successful model establishment, rats in the TD group received 18.63 g·kg⁻¹ of TD by gavage, while those in the mosapride group received 1.605 mg·d⁻¹ of mosapride, and those in the normal group and the model group received 10 ml·kg⁻¹ of normal saline by gavage. All treatments were administered once daily for 7 consecutive days. Twenty-four hours after the last administration, fecal pellet number and fecal water content were measured. After intragastric administration of a 10% activated charcoal suspension, the small intestinal transit rate was calculated 30 minutes later. Serum levels of gastrin (GAS) and motilin (MTL) were measured by ELISA. Colonic histopathology was observed by HE staining, and mucus secretion by Alcian blue-periodic acid-Schiff (AB-PAS) staining. Ultrastructure of colon tissue was examined using transmission electron microscopy. Protein expression levels of C-kit, stem cell factor (SCF), autophagy-related protein 5 (ATG5), Beclin1, vesicle-associated membrane protein B (VAPB), and protein tyrosine phosphatase interacting protein 51 (VAPB-PTPIP51) were measured by Western Blot, and the mRNA levels were detected by real-time PCR. Immunohistochemistry was used to detect SCF, C-kit, Beclin1, and ATG5 expression. The calcium content in colon tissue was determined by ELISA. ResultsCompared to the normal group, rats in the model group showed significantly reduced fecal pellet number, fecal water content, small intestinal transit rate, and serum GAS and MTL levels (P<0.01); the number of goblet cells decreased, and the mucosal and muscular layers of the colon became thinner; mRNA and protein expression levels of ATG5 and Beclin1 in colon tissue significantly increased, while calcium content decreased (P<0.05 or P<0.01); and electron microscopy revealed vacuolar degeneration and increased autophagosomes in colonic cells. Compared to the model group, both TD group and mosapride group showed increased fecal pellet number, fecal water content, small intestinal transit rate, serum GAS and MTL levels, and colonic calcium content, along with decreased Beclin1 and ATG5 protein levels (P<0.05 or P<0.01); the mucosal thickness and goblet cell number increased significantly, and autophagosomes decreased; in the TD group, ATG5 and Beclin1 mRNA levels decreased; in the mosapride group, SCF, VAPB, and PTPIP51 mRNA levels increased, while Beclin1 mRNA decreased (P<0.05 or P<0.01). Compared to the mosapride group, the TD group showed higher fecal pellet number, fecal water content, serum GAS levels, colonic calcium content, and C-kit expression, along with lower ATG5 and Beclin1 levels (P<0.05 or P<0.01). ConclusionTD may improve constipation symptoms by upregulating the VAPB-PTPIP51 complex during mitochondria-endoplasmic reticulum interactions, reducing autophagy of interstitial cells of Cajal, and promoting intestinal motility.

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.

Objective To evaluate the efficacy and safety of modified pelvic floor reconstruction in non-nerve-sparing robot-assisted radical prostatectomy (NNS RARP) for improving postoperative urinary control. Methods A retrospective analysis was conducted on the clinical data of 79 prostate cancer patients who underwent NNS RARP at Tangdu Hospital during Jan.2020 and Dec.2023, including 29 in the reconstruction group, and 50 in the non-reconstruction group. The baseline characteristics including age, body mass index, prostate-specific antigen (PSA) level, clinical stage, prostate volume, and biopsy Gleason score, and perioperative indexes including operation time, intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins were compared between the two groups. Additionally, urinary continence function was assessed before operation and 1,3,6, and 12 months after operation using the international consultation on incontinence questionnaire-short form (ICIQ-SF) and the incontinence quality of life questionnaire score (I-QoL). Results No statistically significant differences were observed in the baseline characteristics between the two groups (P>0.05). The operation time was significantly longer in the reconstruction group than in the non-reconstruction group [ (110.24±15.08) min vs. (101.80±9.89) min, P=0.010]. There were no significant differences in intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins between the two groups (P>0.05). The reconstruction group demonstrated significantly lower ICIQ-SF scores at 1 month [ (10.17±2.16) vs. (11.56±1.66), P=0.002],3 months [ (7.62±1.29) vs. (9.52±1.80), P<0.001], and 6 months postoperatively [ (4.93±1.22) vs. (6.18± 1.67), P=0.001]compared to the non-reconstruction group (adjusted P<0.0125). Conversely, the I-QoL scores were significantly higher in the reconstruction group at 1 month [ (73.32±10.30) vs. (63.88±9.55), P<0.001]and 3 months postoperatively [ (78.91±4.82) vs. (75.66±5.17), P=0.007] (adjusted P<0.0125). However, no significant differences were found in ICIQ-SF or I-QoL scores between the two groups preoperatively and 12 months postoperatively (adjusted P>0.0125). Conclusion The application of modified pelvic floor reconstruction technique in NNS RARP is safe and feasible. Although it slightly prolongs the operation time, it does not increase surgical risks; instead, it effectively promotes early recovery of postoperative urinary continence, thereby significantly enhancing patients'quality of life.

Objective:To analyze the influencing factors of image quality of high-frequency ultrasound at the level of the glottis in healthy adults.Methods:A cross-sectional study was conducted on 433 healthy voluteers who underwent routine neck ultrasound examination at the Second Affiliated Hospital of Xi'an Jiaotong University from October 2023 to April 2024 and met the inclusion criteria. General data of the subjects were collected,and the image quality was graded. Gender,age,height,weight,body mass index,body surface area,thyroid cartilage calcification ratio,thickness of anterior cervical subcutaneous soft tissue and thickness of anterior cervical muscle group were analyzed by using multivariable Logistic regression for the influencing factors of image quality.Results:The display rates of the vocal cord epithelial layer and lamina propria,vocal cord muscle layer and paraglottic space structures in the para-thyroid cartilage section were superior to those in the anterior median section,with statistically significant differences(all P<0.05). There were statistically significant differences in image quality grading among different age groups(all P<0.05),and image quality deteriorated as age increased. Logistic multivariate analysis indicated that gender,age and thyroid cartilage calcification ratio were independent factors affecting image quality(all P<0.05). With age increased,thyroid cartilage calcification at the glottic level could be concentrated in the anterior,middle and posterior parts,respectively,and subsequently,calcification in the anterior and middle or middle and posterior parts gradually fused until complete calcification occurred. Conclusions:High-frequency ultrasound can clearly display the structures of most normal adult larynges at the glottis level,with the lateral section of the thyroid cartilage being superior to the median anterior neck section. As age increases,the degree of thyroid cartilage calcification increases,and image quality worsens.

Objective:Comparative study on the application value of bronchial ultrasound combined with different biopsy methods under thin-layer CT navigation in the diagnosis of malignant peripheral lung lesions.Methods:A retrospective analysis of patients with suspected malignant peripheral lung lesions identified by chest CT from January 2019 to September 2024 at the Cancer Hospital of the Chinese Academy of Medical Sciences and Peking Union Medical College, and Xianyang Central Hospital, who underwent routine bronchoscopy with negative results (209 cases). These patients were diagnosed using bronchial ultrasound under thin-layer CT navigation. The cases were divided into a cryobiopsy group (127 cases) and a conventional forceps biopsy group based on the biopsy method (82 cases). The diagnostic rates of the two groups were statistically analyzed, along with factors influencing the diagnostic rates. The tissue size obtained from both groups was compared, and the occurrence of complications was summarized.Results:This study included 209 cases with 216 peripheral lung lesions. A total of 209 cases with 210 lesions were successfully located through thin-slice CT guidance, resulting in a guiding success rate of 97.2% (210/216). Among the 130 lesions in the cryobiopsy group, 78 lesions were diagnosed as lung malignancies, with a diagnostic rate of 82.1% (64/78) for cryobiopsy in lung malignant lesions. In the forceps biopsy group, 46 of the 86 lesions were diagnosed as lung malignancies, with a diagnostic rate of 87.0% (40/46) for forceps biopsy in lung malignant lesions. There was no statistically significant difference between the two diagnostic rates ( P=0.473). The average longest diameter of tissue obtained by cryobiopsy was (6.11±0.23) mm, while the average longest diameter of tissue obtained by forceps biopsy was (1.58±0.43) mm. There was a statistically significant difference in tissue longest diameter between the two groups ( P<0.001). When the distance from the bronchoscopic tip to the lesion was ≥3 cm and the most distal bronchus visible under bronchoscopy was ≤5th generation, the diagnostic rate of forceps biopsy was higher [83.3%(25/30) and 94.1%(32/34)] than that of cryobiopsy [79.3%(23/29) and 78.0%(46/59)], and the difference was statistically significant ( P<0.05). Regarding complications, one case (1.3%, 1/78) of clinically significant complications occurred in the cryobiopsy group, while no complications occurred in the forceps biopsy group. Conclusions:Under thin-layer CT navigation, bronchial ultrasound combined with different biopsy methods demonstrates a high diagnostic rate for malignant peripheral lung lesions and is safe to operate. Cryobiopsy allows for the collection of larger tissue specimens.

Objective:To analyze the efficacy of phantom-less quantitative computer tomography (PL-QCT) for the diagnosis of osteoporosis in patients with lumbar degenerative diseases.Methods:From October 2021 to October 2023, a total of 1 248 patients with lumbar degenerative disease who did not receive anti-osteoporosis treatment in the Department of Spine Surgery, Tianjin Hospital were retrospectively analyzed. There were 520 males and 728 females, aged 62.31±9.37 years (range, 40-87 years), height 1.66±0.08 m (range, 1.43-1.89 m), weight 69.04±8.27 kg (range, 49-93 kg). The mean body mass index was 26.11±3.67 kg/m 2 (range, 14.40-37.11 kg/m 2). Dual-energy X-ray absorptiometry (DXA) and PL-QCT were used to diagnose osteoporosis, and the detection rates of the two diagnostic methods were compared. The receiver operating characteristic (ROC) curve of PL-QCT for the diagnosis of osteoporosis was drawn, the area under the curve (AUC) and 95% confidence interval (CI), sensitivity and specificity were calculated. Results:Among 1 248 patients with lumbar degenerative diseases, 626 (50.2%) were diagnosed as osteoporosis by PL-QCT, 423(33.9%) were diagnosed by spine DXA, 488(39.1%) were diagnosed by hip DXA and 539 patients(43.2%) were diagnosed by dual-site DXA. The detection rate of osteoporosis of PL-QCT was higher than that of spine DXA (χ 2=193.557, P<0.001), hip DXA (χ 2=322.201, P<0.001) and dual-site DXA (χ 2=94.683, P<0.001), and the difference was statistically significant. Taking the diagnostic results of spinal DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 79%, a specificity of 81%, and an AUC and 95% CI of 0.82(0.79, 0.85). Taking the diagnostic results of hip DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 85%, a specificity of 55%, and an AUC and 95% CI of 0.75(0.71, 0.78). Taking the diagnostic results of two-site DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 72%, a specificity of 75%, and an AUC and 95% CI of 0.81(0.78, 0.83). Conclusion:Compared with DXA, PL-QCT has a higher detection rate of osteoporosis in patients with degenerative lumbar spine disease and good diagnostic efficacy.
