Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Hepatocellular carcinoma (HCC) is the most common primary liver cancer, and its high mortality rate is closely associated with the unsatisfactory diagnostic and monitoring methods for HCC at present. Some microRNAs (miRNAs) play an important role in the development and progression of HCC, and their abnormal expression is a common phenomenon in HCC pathology; in addition, miRNAs can be released into the circulating blood and remain stable in blood. By reviewing the research advances in the role of miRNAs in HCC, it is pointed out that miRNAs are expected to become potential markers for the early diagnosis, monitoring and treatment, and prognostic evaluation of HCC, and this article also analyzes related issues in the clinical verification of such potential markers.

OBJECTIVE: To investigate the effect of a modified Wuzi Yanzong Pill (, WZYZP) on the male rats' testis after microwave radiation, as well as its potential mechanism. METHODS: Forty-five male rats were randomly assigned to three groups: the control group, the radiation group, and the WZYZP group. The rats in the radiation group and WZYZP group were exposed to microwave radiation for 15 min once, while the rats in the control group were not exposed to any radiation. The rats in the WZYZP group were given a modified of WZYZP by gavage daily for 7 days. Apoptosis in the testis was evaluated using terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay. Histopathological alterations of the testis were observed by haematoxylin-eosin (HE) staining. Tat-interactive protein, 60kD (Tip60) and p53 expressions were determined by Western blotting. RESULTS: The apoptosis index (AI) in the radiation group was higher than that of the WZYZP group and control group on day 1 (D1), day 7 (D7) day 14 (D14) after radiation (P<0.05). The seminiferous tubules were of normal morphology in the control group. In the radiation group, the partial seminiferous tubules were collapsed, basement membranes of the seminiferous epithelia became detached. WZYZP could restore the morphological changes. There was no expression of Tip60 among the three groups on D7 and D14. The expression of p53 was higher in the radiation group than in the control group (P<0.05). WZYZP could down-regulate the rising p53 induced by radiation on D7 and D14 (P<0.05). CONCLUSION A modified WZYZP may affect germ cells, and its protective effects may partly result from its ability to intervene in Tip60 mediated apoptosis.

Objective To compare the efficacy and adverse effects of hypofractionated radiotherapy versus conventionally fractionated radiotherapy for intermediate-to high-risk localized prostate cancer.Methods A literature search was performed in PubMed, Embase, Web of Science, CNKI, VIP database, and Wanfang Data to collect the controlled clinical trials of hypofractionated radiotherapy versus conventionally fractionated radiotherapy in patients with intermediate-to high-risk localized PCa published up to August 31, 2016.Stata 12.0 was used for meta-analysis.The difference between two groups was estimated by calculating the hazard ratio (HR) or risk ratio (RR) with 95%confidence interval (CI).ResultsAccording to the inclusion and exclusion criteria, a total of 5 controlled clinical trials involving 1621 patients with PCa were included in this meta-analysis.The meta-analysis showed that overall survival (HR=1.00, 95%CI:0.85-1.17, P=0.980) and biochemical failure (RR=0.87, 95%CI:0.68-1.12, P=0.274) were comparable between the two groups.Compared with the conventionally fractionated radiotherapy, the incidence of acute gastrointestinal adverse events (grade≥2) was significantly higher in the hypofractionated radiotherapy (RR=1.94, 95%CI:1.23-3.06, P=0.004).However, there were no significant differences in the incidence of acute genitourinary adverse events (grade≥2)(RR=1.03, 95%CI:0.92-1.14,P=0.626), late gastrointestinal adverse events (grade≥2)(RR=1.17,95%CI:0.90-1.51, P=0.238), and late genitourinary adverse events (grade≥2)(RR=1.11, 95%CI:0.94-1.30, P=0.228) between the two groups.Conclusions Conventionally fractionated radiotherapy and hypofractionated radiotherapy have comparable therapeutic effects in patients with intermediate-to high-risk localized PCa.Although the patients treated with hypofractionated radiotherapy have a higher incidence of acute gastrointestinal adverse events than those treated with conventionally fractionated radiotherapy, the incidence of late gastrointestinal and genitourinary adverse events is comparable between the two groups of patients and the adverse effects are tolerable.

OBJECTIVETo study source apportionment of atmospheric PM10 (particle matter ≤ 10 µm in aerodynamic diameter) and PM2.5 (particle matter ≤ 2.5 µm in aerodynamic diameter) in Beijing,Urumqi and Qingdao, China.

METHODSThe atmospheric particle samples of PM10 and PM2.5 collected from Beijing between May 17th and June 18th, 2005, from Urumqi between April 20th and June 1st, 2006 and from Qingdao between April 4th and May 15th, 2005, were detected to trace the source apportionment by factor analysis and enrichment factor methods.

RESULTSIn Beijing, the source apportionment results derived from factor analysis model for PM10 were construction dust and soil sand dust (contributing rate of variance at 45.35%), industry dust, coal-combusted smoke and vehicle emissions (contributing rate at 31.83%), and biomass burning dust (13.57%). The main pollution element was Pb, while the content (median (minimum value-maximum value)was 0.216 (0.040-0.795) µg/m(3)) . As for PM2.5, the sources were construction dust and soil sand dust (38.86%), industry dust, coal-combusted smoke and vehicle emissions (25.73%), biomass burning dust (13.10%) and burning oil dust (11.92%). The main pollution element was Zn (0.365(0.126-0.808) µg/m(3)).In Urumqi, source apportionment results for PM10 were soil sand dust and coal-combusted dust(49.75%), industry dust, vehicle emissions and secondary particles dust (30.65%). The main characteristic pollution element was Cd (0.463(0.033-1.351) ng/m(3)). As for PM2.5, the sources were soil sand dust and coal-combusted dust (43.26%), secondary particles dust (22.29%), industry dust and vehicle emissions (20.50%). The main characteristic pollution element was As (14.599 (1.696-36.741) µg/m(3)).In Qingdao, source apportionment results for PM10 were construction dust (30.91%), vehicle emissions and industry dust (29.65%) and secondary particles dust (28.99%). The main characteristic pollution element was Pb (64.071 (5.846-346.831) µg/m(3)). As for PM2.5, the sources were secondary particles dust, industry dust and vehicle emissions (49.82%) and construction dust (33.71%). The main characteristic pollution element was Pb(57.340 (5.004-241.559) µg/m(3)).Enrichment factors of Zn, Pb, As and Cd in PM2.5 were higher than those in PM10 both in Beijing and Urumqi.

CONCLUSIONThe major sources of the atmospheric particles PM10 and PM2.5 in Beijing were cement dust from construction sites and sand dust from soil; while the major sources of those in Urumqi were pollution by smoke and sand dust from burning coal. The major sources of the atmospheric particles PM10 in Qingdao were cement dust from construction sites; however, the major sources of PM2.5 there were secondary particles dust, industry dust and vehicle emissions. According to our study, the heavy metal elements were likely to gather in PM2.5.

OBJECTIVETo investigate the effect of metoclopramide on capsule endoscopy (CE) examination.

METHODSTotal 116 patients referred for CE were randomized into two groups with 58 patients in each group. In treatment group patients received 10 mg metoclopramide intramuscular injection after swallowing the capsule and in control group no metoclopramide was administered. The gastric transit time, small bowel transit time, complete endoscopy rate were observed in both groups.

RESULTSThe CE examination was completed in 51 patients of treatment group (87.9%) and 48 of control group (84.2%). Mean gastric transit time was (32.45 ± 29.63) min in treatment group and (45.81 ± 40.01)min in control group, there was significant difference between two groups (P<0.05). Mean small bowel transit time was (252.69 ± 113.29) min in treatment group and (258.75 ± 83.83) min in control group, there was no significant difference between two groups (P>0.05).

CONCLUSIONMetoclopramide may reduces gastric transit time, but not effect small bowel transit time,which suggests that it might increase the likelihood of complete small-bowel examination in patients undergoing capsule endoscopy.
