Small intestinal bacterial overgrowth(SIBO)is a clinically common but poorly recognized disease with clinical symptoms that overlap with those of functional gastrointestinal disorders(FGID). FGID is a common risk factor for the occurrence of SIBO,and its SIBO incidence rate is significantly higher than that of healthy people,and has a certain correlation. Intestinal microbiota dysbiosis(including SIBO)plays an important role in the pathophysiology of FGID. At present,the diagnosis and treatment of SIBO still face challenges,and the treatment plan of FGID is gradually introduced into the treatment of SIBO. SIBO and FGID are closely related in clinical manifestations,incidence rate,pathophysiology,treatment and other aspects,but there is little research on the relationship between them. Prospective and large-scale clinical research is still needed to improve understanding and diagnostic accuracy.This article reviews the research progress on the relationship between SIBO and FGID.

Objective:To compare gamma pass rates for ultra-long target volumes of cervical cancer between individual measurements by moving the phantom isocenter and segmented measurements combined with merging and to assess the influence of scattering blocks on verification result during segmented measurements.Methods:A retrospective study was conducted on 24 cervical cancer patients with ultra-long target volumes (lengths: 23.5–36.0 cm) treated using helical tomotherapy. Two measurement methods were used to verify the gamma pass rates: individual measurements by moving the phantom isocenter and segmented measurements combined with merging. For the first measurement method, the patients′ treatment plans were transferred to the ArcCheck phantom. After the dose distribution was calculated and exported, the gamma pass rates measured and calculated were compared. For the segmented measurements, a 50-cm-long virtual phantom was imported, and the treatment plans of patients were then transferred to the virtual phantom. Afterward, the dose distribution of the virtual phantom was calculated and exported. Then, two dose measurements were conducted under upward and downward setup of the ArcCheck phantom. Two dose measurement files were obtained and then fused to produce a merged file. Then, the γ pass rates were calculated. Repeated measurements were conducted after scattering blocks were installed. The γ-pass rates were assessed using varying dose criteria.Results:Under various evaluation criteria, no statistically significant differences in γ pass rates were observed between the individual measurements by moving the phantom isocenter and the segmented measurement in the presence of scattering blocks ( P > 0.05). In contrast, there existed statistically significant differences in γ pass rates between the individual measurements by moving the phantom isocenter and the segmented measurement in the absence of scattering blocks according to the (global) criterion of 3%/2 mm absolute dose ( Z = -2.31, P = 0.02). Additionally, the segmented measurement in the presence of scattering blocks enhanced pass rates, with statistical significant difference under the criterion of 3%/2 mm relative dose ( Z = -2.11, P = 0.04). Conclusions:In the case where ArcCheck is used to measure the dose distribution of ultra-long target volumes in cervical cancer, it is advisable to preferentially use individual measurements by moving the phantom isocenter. When segmented measurements combined with merging are required, it is necessary to install scattering blocks during measurements. This will improve γ-pass rates during verification and ensure the accuracy of dose verification.

Objective:To explore the effect of ginsenoside Rg1 on spermatogenic dysfunction in mice caused by diabetes and its mechanism of action.Methods:Eighteen male C57BL mice were randomly divided into control group, the model group and the ginsenoside Rg1 group by completely random method, with 6 mice in each group. Type 2 diabetes models were established in the model group and the ginsenoside Rg1 group by a high-fat diet combined with intraperitoneal injection of streptozotocin, while control group was injected with the same amount of normal saline. After successful modeling, control group was given a regular diet for 8 weeks, while the model group and ginsenoside Rg1 group were given a high-fat diet for 8 weeks. The ginsenoside Rg1 group was also treated with ginsenoside Rg1 medication. Reproductive hormone levels were detected by enzyme-linked immunosorbent assay test kits, and Western blotting was used to detect the expressions of apoptosis-related proteins (Bcl2 protein, Caspase-3 protein, Bax protein), autophagy-related proteins (P62, LC3Ⅰ, LC3Ⅱ, Beclin1), β-Catenin protein, mTOR protein, LAMP1 protein and transcription factor EB. The body weight, blood glucose levels, testicular index of mice in each group were compared, as well as the testicular injury status.Results:The body weight [(18.77±1.14) g], testosterone level [(141.07±8.47) ng/L], follicle-stimulating hormone level [(9.19±0.74) U/L], and luteinizing hormone level [(1 497.91±99.57) pg/L] of mice in the model group were significantly lower than those in the control [(31.57±2.35) g, P<0.001; (171.50±11.76) ng/L, P<0.001; (12.46±1.54) U/L, P<0.001; (1 807.29±92.76) pg/L, P<0.001]; fasting blood glucose level [(20.82±1.11) mmol/L], glycosylated hemoglobin (12.67%±1.03%), the testis index (0.65%±0.03%) were significantly higher than those in the control [(6.40±1.34) mmol/L, P<0.001; 5.17%±1.17%, P<0.001; 0.48%±0.04%, P<0.001]. Compared with the model group, the body weight [(22.62±0.92) g, P=0.023], testosterone level [(172.63±9.20) ng/L, P<0.001], follicle-stimulating hormone level [(12.37±1.15) U/L, P<0.001], and luteinizing hormone level [(1 847.80±108.80) pg/L, P<0.001] of mice in the ginsenoside Rg1 group increased significantly, fasting blood glucose level [(18.63±1.14) mmol/L, P=0.017], glycosylated hemoglobin (8.50%±1.05%, P<0.001) and testicular index (0.54%±0.02%, P<0.001) decreased significantly. Compared with the control, the expressions of P62 ( P=0.039), LC3Ⅱ/LC3Ⅰ( P<0.001), Beclin1 ( P=0.002) and mTOR ( P=0.036) in the testicular tissue of mice in the model group all increased, the expression of β-Catenin ( P<0.001), LAMP1 ( P=0.005), transcription factor EB ( P<0.001) all decreased. Compared with the model group, the expressions of autophagy-related proteins P62 ( P=0.048), LC3Ⅱ/LC3Ⅰ( P<0.001) , Beclin1 ( P=0.023) and mTOR ( P=0.005) in the ginsenoside Rg1 group all decreased, while the expression of β-Catenin ( P=0.001), LAMP1 ( P=0.011) and transcription factor EB ( P=0.022) all increased. Transmission electron microscopy detected a decrease in the number of autophagosomes in the testicles of mice in the model group, and it improved after drug intervention. The HE staining showed that the testes of mice in the model group exhibited phenotypes such as the shedding and disorganization of spermatogenic cells, while ginsenoside Rg1 was able to improve these phenotypes. Conclusion:Ginsenoside Rg1 can improve testicular injury caused by diabetes in mice by regulating autophagy.
5.Key issues and improvements in the clinical governance of osteoporotic fractures
Chinese Journal of Orthopaedics 2025;45(12):760-766
Global population aging has exacerbated the clinical management challenges of osteoporotic fractures, especially during the high-risk period of re-fracture within 2 years after fracture. Although significant progress has been made in the comprehensive management of osteoporotic fractures in China, which has improved patient prognosis. There are still many challenges in clinical practice, including the mismatch between traditional implants and osteoporotic bone structure, the clinical management bottlenecks from treatment to rehabilitation of osteoporotic fractures (such as low implementation rates of drug treatment, poor drug compliance, and inadequate rehabilitation awareness), as well as the underdevelopment and regional disparities of fracture liaison services in China. To address these challenges, we propose three strategic improvements: transitioning from a purely mechanical fixation to a combined "mechanical-biological" synergistic treatment model, optimizing a full-cycle management pathway for osteoporotic fractures based on the enhanced recovery after surgery, and developing a systematic and intelligent approach for re-fracture prevention (such as establishing exclusive management teams, constructing specialized databases, and developing intelligent data platforms). These strategies are expected to enable efficient screening, precise monitoring, and full lifecycle management of patients with osteoporotic fractures, thereby enhancing the effectiveness and precision of clinical management and offering new insights and practical pathways for improving the treatment and care of osteoporotic fractures in China.

Objective:To explore the application value of selective transurethral plasma kinetic resection of the prostate (PKRP) and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of diabetes benign prostatic hyperplasia (BPH).Methods:A total of 114 patients with diabetes BPH diagnosed and treated in Lanxi People′s Hospital from September 2020 to September 2023 were retrospectively selected and divided into resection group and enunciation group according to the operation method, with 57 cases in each group. The resection group received selective PKRP and the enucleation group received HoLEP. Preoperative and postoperative stress response indexes were compared between the two groups, as well as urodynamics indexes and complications before and 3 months after surgery.Results:The quality of prostatectomy in the enucleation group was higher than that in the resection group : (39.68 ± 3.02) g vs. (30.25 ± 2.84) g; the operation time, intraoperative blood loss, bladder irrigation time and hospital stay in the enucleation group were lower than those in the resection group: (63.84 ± 5.44) min vs. (72.58 ± 11.33) min, (62.38 ± 15.84) ml vs. (89.54 ± 17.91) ml, (1.84 ± 0.71) d vs. (2.35 ± 0.80) d, (4.98 ± 1.16) d vs.(5.64 ± 1.05) d, there were statistical differences ( P<0.05). The levels of serum cortisol (COR) and norepinephrine (NE) in the enucleation group at 1, 3 d after surgery were lower than those in the excision group [1 d after surgery: (279.76 ± 17.82) ng/L vs. (289.51 ± 18.37) ng/L, (287.44 ± 26.51) ng/L vs. (300.47 ± 28.35) ng/L; 3 d after surgery: (236.58 ± 15.98) ng/L vs. (247.46 ± 16.47) ng/L, (269.13 ± 23.51) ng/L vs. (278.76 ± 25.62) ng/L, there were statistical differences ( P<0.05). Three months after surgery, the maximum urine flow rate in the enucleation group was higher than that in the excision group : (21.51 ± 3.82) ml/s vs. (18.74 ± 4.17) ml/s, and the residual urine volume (RUV) was lower than that in the excision group : (8.47 ± 3.06) ml vs. (10.25 ± 2.43) ml, there were statistical differences ( P<0.05). There was no significant difference in the incidence of urethral stricture and urinary incontinence between the two groups ( P>0.05). Conclusions:HoLEP for the treatment of diabetes BPH can reduce stress response, promote disease recovery, improve urodynamics, and has a safety comparable to that of selective PKRP.
