Objective:
The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) demonstrates high specificity with relatively limited sensitivity for diagnosing hepatocellular carcinoma (HCC) in high-risk patients. This study aimed to explore the possibility of improving sensitivity by combining CT/MRI LI-RADS v2018 with second-line contrast-enhanced ultrasound (CEUS) LI-RADS v2017 using sulfur hexafluoride (SHF) or perfluorobutane (PFB).
Materials and Methods:
This retrospective analysis of prospectively collected multicenter data included high-risk patients with treatment-naive hepatic observations. The reference standard was pathological confirmation or a composite reference standard (only for benign lesions). Each participant underwent concurrent CT/MRI, SHF-enhanced US, and PFB-enhanced US examinations. The diagnostic performances for HCC of CT/MRI LI-RADS alone and three combination strategies (combining CT/ MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or a modified algorithm incorporating the Kupffer-phase findings for PFB [modified PFB]) were evaluated. For the three combination strategies, apart from the CT/MRI LR-5 criteria, HCC was diagnosed if CT/MRI LR-3 or LR-4 observations met the LR-5 criteria using LI-RADS SHF, LI-RADS PFB, or modified PFB.
Results:
In total, 281 participants (237 males; mean age, 55 ± 11 years) with 306 observations (227 HCCs, 40 non-HCC malignancies, and 39 benign lesions) were included. Using LI-RADS SHF, LI-RADS PFB, and modified PFB, 20, 23, and 31 CT/MRI LR-3/4 observations, respectively, were reclassified as LR-5, and all were pathologically confirmed as HCCs. Compared to CT/MRI LI-RADS alone (74%, 95% confidence interval [CI]: 68%–79%), the three combination strategies combining CT/MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or modified PFB increased sensitivity (83% [95% CI: 77%–87%], 84% [95% CI: 79%–89%], 88% [95% CI: 83%–92%], respectively; all P < 0.001), while maintaining the specificity at 92% (95% CI: 84%–97%).
Conclusion
The combination of CT/MRI LI-RADS with second-line CEUS using SHF or PFB improved the sensitivity of HCC diagnosis without compromising specificity.

ObjectiveTo investigate pulmonary function levels and associated influencing factors among rural elderly in Guangzhou, to identify high-risk populations for poor pulmonary function, and to reveal the relationship between the influencing factors of pulmonary function. MethodsWe recruited 1 500 residents aged 60 to 94 years from rural area of Conghua District, Guangzhou City using convenience sampling in 2023. Data on demographics, body measurements, medical history and lifestyle were collected via face-to-face questionnaires and physical examination. Meanwhile, expiratory function parameters including forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC, and the prevalence of airflow obstruction (AFO) were assessed using a portable spirometer. Age and sex distribution of pulmonary function in older adults at 5-year intervals was reported, and risk factors of AFO using multifactorial logistic regression models were analyzed. Furthermore, path analysis was further employed to explore the role of lifestyle in the association between other influencing factors and lung function. ResultsAmong the 1 500 participants, the median age was 71 years (67-75), and 44.2% were male. Subjects identified as AFOs were generally older, more likely male, less educated, and had lower rates of moderate to vigorous physical activity (<1 time/week) and lower lean body mass. Mean FEV1/FVC ratio was (82.0±16.4) %. FEV1/FVC was (79.80±17.58) % in men and (83.66±15.22) % in women. Older age, lower education, male sex and leanness were negatively associated with all pulmonary function outcomes (all P values<0.05). Path analysis identified that age, gender, marital status, occupation and income may influence pulmonary function indirectly through lifestyle. ConclusionRural elderly in Guangzhou exhibited lower pulmonary function levels, and male sex, non-married status, advanced age, lower education, smoking habits, insufficient engagement in moderate to vigorous physical activity, and lean body type were all associated with worse pulmonary function.

OBJECTIVE:
To compare the effect of acupuncture-moxibustion on idiopathic facial palsy (IFP) at acute phase and recovery phase.
METHODS:
According to whether received acupuncture-moxibustion at acute phase or not, 198 IFP patients were divided into an early-phase intervention group (118 cases) and a non-early-phase intervention group (80 cases). With the propensity score matching employed, 70 cases were included in each group. On the basis of the conventional treatment of western medicine, acupuncture-moxibustion was supplemented in the two groups. In the early-phase intervention group, acupuncture-moxibustion was delivered at the acute phase (duration of illness≤7 days); in the non-early-phase intervention group, acupuncture-moxibustion was operated at the recovery phase (duration of illness>7 days). At the acute phase, warm needling was performed at Yifeng (TE17), Xiaguan (ST7), Hegu (LI4) and Zusanli (ST36) on the affected side; and at the recovery phase, electroacupuncture was delivered at Cuanzhu (BL2), Sizhukong (TE23) and Yangbai (GB14), etc. on the affected side, with the disperse-dense wave and 2 Hz/100 Hz of frequency. The intervention was operated for 30 min each time, once every two days, three treatments weekly and for 4 weeks. Before treatment, 1 week and 4 weeks of treatment, the House-Brackmann (H-B) facial nerve function grade, the score of Sunnybrook facial nerve function, and the score of facial disability index (FDI) were compared between the two groups. The clinical effect in 1 and 4 weeks of treatment and safety were evaluated.
RESULTS:
In 1 and 4 weeks of treatment, the H-B grade was improved when compared with that before treatment in each group (P<0.05), and in 4 weeks of treatment, H-B grade in the early-phase intervention group was superior to that of the non-early-phase intervention group (P<0.05). In 1 and 4 weeks of treatment, Sunnybrook scores and the scores of physical function of FDI were elevated in comparison with those before treatment in the two groups (P<0.05); and in 4 weeks of treatment, the elevation of these two indexes in the early-phase intervention group was greater than that of the non-early-phase intervention group (P<0.05). In 4 weeks of treatment, the scores of social function in FDI were reduced when compared with those before treatment in the two groups (P<0.05). In 4 weeks of treatment, the total effective rate (97.1%, 68/70) in the early-phase intervention group was higher than that (87.1%, 61/70) of the non-early-phase intervention group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05).
CONCLUSION
Acupuncture-moxibustion therapy starting at the acute phase is more beneficial to the functional recovery of the impaired facial nerve than at the recovery phase in the IFP patients.

OBJECTIVE:
To observe the effect of electroacupuncture combined with enhanced recovery after surgery (ERAS) protocol on promoting intestinal function in patients after gastric cancer surgery.
METHODS:
Forty-four patients who underwent radical gastrectomy for gastric cancer were randomly divided into an experimental group (22 cases, 3 cases were excluded) and a control group (22 cases, 4 cases were excluded). Both groups received treatment under ERAS protocol, the experimental group was given electroacupuncture at bilateral Neiguan (PC6), Hegu (LI4), Zusanli (ST36) and Quchi (LI11), disperse-dense wave was selected, with frequency of 2 Hz/100 Hz. The control group received placebo electroacupuncture intervention, with the same acupoints as the experimental group, electrode pads were placed on the acupoints without electrical stimulation. Each session lasted 30 min, starting from 1 h after surgery, once every 24 h, until the patient resumed anal flatus. The intestinal sound rate of both groups was observed 24 h before surgery and 24, 48 h after surgery. The bowel sound recovery time (BSRT), time to first anal flatus, time to first defecation, and tolerance to oral enteral nutrition suspension were compared between the two groups. The levels of serum C-reactive protein (CRP), interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured 24 h before surgery and 24 h after surgery in both groups.
RESULTS:
The intestinal sound rate 24 h after surgery was decreased compared with that 24 h before surgery in the two groups (P<0.05), the intestinal sound rate 24, 48 h after surgery in the experimental group was higher than that in the control group (P<0.05). The BSRT in the experimental group was earlier than that in the control group (P<0.05) .The levels of serum CRP, IL-6, IL-10 24 h after surgery in the experimental group were higher than those 24 h before surgery (P<0.05), while the levels of serum CRP, IL-4, IL-6, IL-10, IFN-γ in the control group were higher than those 24 h before surgery (P<0.05); the levels of serum CRP、IL-4、IFN-γ 24 h after surgery in the experimental group were lower than those in the control group (P<0.05) .The tolerance rate of oral enteral nutrition suspension in the experimental group was 84.2% (16/19), which was higher than 50.0% (9/18) in the control group (P<0.05).
CONCLUSION
Electroacupuncture combined with ERAS protocol can improve the intestinal motility, shorten the BSRT, enhance the tolerance of oral intake, and reduce inflammatory response in patients after gastric cancer surgery.

OBJECTIVE:
To observe the effects of acupoint catgut embedding (ACE) on gut microbiota and fecal short-chain fatty acids (SCFAs) levels in patients with Parkinson's disease (PD) with constipation.
METHODS:
A total of 80 PD patients with constipation were randomly divided into an observation group and a control group, 40 cases in each group. Additionally, 40 healthy individuals were recruited as a healthy control group. The control group received conventional Western medical treatment for PD combined with polyethylene glycol (PEG), once daily for eight weeks. The observation group received additional ACE treatment at bilateral Tianshu (ST25), Zusanli (ST36), and Shangjuxu (ST37), once every two weeks for eight weeks. The healthy control group received no intervention. The spontaneous bowel movements (SBMs) per week and patient assessment of constipation quality of life (PAC-QOL) scores were assessed at baseline and after treatment in the two groups. Fecal samples were collected at the end of treatment for the observation and the control groups and at baseline for the healthy control group. Gut microbiota composition and diversity were analyzed using 16S rRNA method, and SCFA levels were measured using high-performance liquid chromatography (HPLC).
RESULTS:
Compared before treatment, the observation group showed a significant increase in SBMs (P<0.01), and PAC-QOL scores including physical discomfort, psychosocial discomfort, worry and concern, and total score were significantly reduced (P<0.01) after treatment; the control group also showed a reduction in PAC-QOL total score after treatment (P<0.01). After treatment, the observation group had significantly more SBMs (P<0.01), and lower PAC-QOL physical discomfort, psychosocial discomfort, worry and concern scores, and total score (P<0.01), and higher PAC-QOL satisfaction score (P<0.01) than the control group. Compared with the healthy control group, the control group showed decreased Chao1 and Ace indices (P<0.01). Compared with the healthy control group, the relative abundance of Prevotella and Roseburia was increased (P<0.05), while that of Enterobacter and Ruminococcus torques (six species in total) was decreased (P<0.05) in the control group. Compared with the control group, the observation group had increased relative abundance of Dialister, Parabacteroides, and Ruminococcus torques (P<0.05), and decreased relative abundance of Prevotella and Eubacterium ruminantium (P<0.05). Compared with the healthy control group, the control group had increased fecal SCFA levels (P<0.05); compared with the control group, the observation group had reduced fecal SCFA levels (P<0.05). Compared with the healthy control group, acetic acid, propionic acid, and butyric acid levels were elevated in the control group (P<0.05); compared with the control group, acetic acid, propionic acid, and butyric acid levels were decreased in the observation group (P<0.05).
CONCLUSION
ACE could increase spontaneous bowel movements and improve the quality of life in PD patients with constipation, which may be related to the regulation of gut microbiota composition and SCFA levels.

Journal of Southern Medical University 2025;45(8):1581-1588
OBJECTIVES:
To investigate the impact of prenatal fear stress on placental amino acid transport and emotion and cognition development in offspring rats.
METHODS:
Thirty pregnant Wistar rats were randomized equally into control and fear stress (induced using an observational foot shock model) groups. In each group, placental and serum samples were collected from 6 dams on gestational day 20, and the remaining rats delivered naturally and the offspring rats were raised under the same conditions until 8 weeks of age. Emotional and cognitive outcomes of the offspring rats were assessed with behavioral tests, and placental structure was examined using HE staining. Bioinformatics analysis was used to identify differentially expressed placental transporter genes under fear stress. The expressions of system A and system L amino acid transporters, along with other specialized transporters, were detected using qRT-PCR and Western blotting. Fetal serum amino acid concentrations were determined by HPLC. The correlations between fetal amino acid levels and behavioral outcomes of the offspring rats were analyzed.
RESULTS:
The dams with fear stress showed reduced open-field activity and increased freezing behavior with significantly decreased placental weight, fetal weight, and fetal-to-placental ratio. Bioinformatics analysis revealed 28 differentially expressed transporter genes involved mainly in amino acid transport. In the fear stress group, fetal serum amino acid levels were significantly lowered and Slc38a1, Slc43a1, Slc43a2, Slc7a8, Slc6a6, Slc1a1 and Slc6a9 mRNA and protein expressions were all downregulated. The offspring rats in fear stress group exhibited decreased novel object preference and spontaneous alternation with reduced open arm exploration and increased immobility in emotional tests. Lower early-life amino acid levels was found to correlate with impaired adult cognition.
CONCLUSIONS
Prenatal fear stress in rats impairs placental amino acid transporter expression and reduces fetal serum amino acid levels, potentially contributing to long-term cognitive deficits in the offspring rats.
