Background/Aims:
The performance of machine learning (ML) in predicting the outcomes of patients with hepatocellular carcinoma (HCC) remains uncertain. We aimed to develop risk scores using conventional methods and ML to categorize early-stage HCC patients into distinct prognostic groups.
Methods:
The study retrospectively enrolled 1,411 consecutive treatment-naïve patients with the Barcelona Clinic Liver Cancer (BCLC) stage 0 to A HCC from 2012 to 2021. The patients were randomly divided into a training cohort (n=988) and validation cohort (n=423). Two risk scores (CATS-IF and CATS-INF) were developed to predict overall survival (OS) in the training cohort using the conventional methods (Cox proportional hazards model) and ML-based methods (LASSO Cox regression), respectively. They were then validated and compared in the validation cohort.
Results:
In the training cohort, factors for the CATS-IF score were selected by the conventional method, including age, curative treatment, single large HCC, serum creatinine and alpha-fetoprotein levels, fibrosis-4 score, lymphocyte-tomonocyte ratio, and albumin-bilirubin grade. The CATS-INF score, determined by ML-based methods, included the above factors and two additional ones (aspartate aminotransferase and prognostic nutritional index). In the validation cohort, both CATS-IF score and CATS-INF score outperformed other modern prognostic scores in predicting OS, with the CATSINF score having the lowest Akaike information criterion value. A calibration plot exhibited good correlation between predicted and observed outcomes for both scores.
Conclusions
Both the conventional Cox-based CATS-IF score and ML-based CATS-INF score effectively stratified patients with early-stage HCC into distinct prognostic groups, with the CATS-INF score showing slightly superior performance.

OBJECTIVE:
To investigate the expression of CSF3R mutation in acute myeloid leukemia (AML) and analyze its clinical characteristics and prognosis.
METHODS:
A retrospective study was conducted in 212 patients with AML who were newly diagnosed in the Second Hospital of Shanxi Medical University from January 1th 2018 to June 30th 2021, including 22 patients with CSF3R mutations as mutation group and 190 patients with CSF3R wild type [66 cases of them were screened by propensity score matching (PSM), as control group]. The early efficacy and survival between the two groups were compared.
RESULTS:
The median age of patients in the mutation group was 50(17-73) years old, and the ratio of male to female was 1.2:1 The main types were AML with maturation (11 cases) and acute myelomonocytic leukemia (9 cases). Prognostic stratification was carried out according to the risk stratification system of the European leukemia network in 2017, with 16 cases (72.73%) in the middle and high-risk group. At the initial diagnosis, the median count of white blood cell (WBC) was 44.75(1.30-368.71)×109/L, among which 15 cases (68.18%) were >10×109/L, and the median count of platelet (PLT) was 24(4-55)×109/L. CSF3R T618I (68.18%) was a common mutation site, which had concomitant gene mutations, in which CEBPA mutation was the most common (10 cases, 45.45%), but only existed in CSF3R T618I mutation. The CR/CRi rate was 68.18% and 71.21% in the mutant group and the control group (P >0.05), the median over all survival time was 15 months and 9 months (P >0.05), and the median disease-free survival time was 8 months and 4 months (P >0.05), respectively.
CONCLUSION
Most AML patients with CSF3R mutation are middle-aged patients, the main types are AML with maturation and acute myelomonocytic leukemia, and most of them have middle and high-risk prognosis. CSF3R mutation may not be an independent prognostic marker for newly diagnosed AML patients.

ObjectiveTo investigate the role of protein kinase B (Akt) overexpression in the inhibition of human bladder cancer 5637 cell proliferation by erianin and related mechanisms. MethodThe 5637 cells stably over-expressing Akt were induced using the lentivirus vector. The 5637 cells infected with the empty vector were classified into blank group. Then the Akt group, empty vector combined with erianin (62.5 μg·L-1) group, and Akt combined with erianin (62.5 μg·L-1) group were set up. The cell viability was detected by cell counting kit-8 (CCK-8) assay, and the clone formation of 5637 cells in each group was determined in the clone formation experiment. The cell cycle distribution was detected by flow cytometry. Western blot was used to assay the protein expression levels of phosphorylated (p)-Akt, Akt, p21. The glycolysis of 5637 cells was determined in glucose uptake and lactate secretion assays. ResultCompared with the blank group, erianin inhibited the proliferation of bladder cancer 5637 cells (P<0.05). Overexpression of Akt partially reversed the inhibitory effect of erianin on the proliferation of bladder cancer 5637 cells (P<0.05). Clone formation assay showed that erianin inhibited the clone formation of bladder cancer 5637 cells (P<0.05), which was partially reversed by the overexpressed Akt (P<0.05). As revealed by comparison with the blank group, erianin arrested the bladder cancer 5637 cells in G1 phase (P<0.05), which was also reversed by the overexpressed Akt (P<0.05). Western bolt showed that erianin promoted the expression of p21 but suppressed the expression of p-Akt and Akt (P<0.05). By contrast, the overexpression of Akt down-regulated the elevated p21 protein expression induced by erianin (P<0.05). Compared with the blank group, erianin inhibited the glucose uptake and lactate secretion of bladder cancer 5637 cells (P<0.05). Overexpression of Akt weakened the inhibitory effect of erianin against the glycolysis of 5637 cells (P<0.05). ConclusionErianin is able to inhibit the proliferation of bladder cancer 5637 cells, promote the expression of p21, and inhibit the expression of p-Akt. Overexpressed Akt reduces the inhibitory effect of erianin on the proliferation of bladder cancer 5637 cells, suggesting that Akt plays an important role in the inhibition of 5637 cell proliferation by erianin, which has provided a new target for the application of erianin in the treatment of bladder cancer.

Objective To investigate the MR features of different clinical staging of scapulohumeral periarthritis and provide relevant support data for the clinical staging of scapulohumeral periarthritis, so as to guide clinical treatment. Methods 30 patients with scapulohumeral periar-thritis received in the hospital from June 2015 to February 2017 were selected to form the observation group and 8 same-sex and same-aged volunteers without such disease were selected to form the control group. MR imaging was used to observe and measure the structure of shoulder joint of the people in the two groups and statistical analysis was performed to analyze the changes in the structure of the shoulder around dif-ferent clinical stages. Results The thickness of joint capsule and coracohumeral ligament ( CHL) , the ratio of subcoracoid fat triangle re-placed were significantly greater in patients with scapulohumeral periarthritis than those in the control group, and the difference was statisti-cally significant (P<0. 05). Comparing the thickness of joint capsule in the third stage of the scapulohumeral periarthritis group compare with those in the first and second stages, the difference was statistically significant (P<0. 05). There was no statistically significant differ-ence (P>0. 05) in the thickness of the coracohumeral ligament and the ratio of subcoracoid fat triangle replaced in the scapulohumeral peri-arthritis group between the 1st, 2nd and 3rd stages. Conclusion Patients with different stages have different structures around the shoulder joints. The thickness of joint capsule can be used as an important reference for diagnosing scapulohumeral periarthritis and can guide the clin-ical staging. The thickness of coracohumeral ligament and the ratio of subcoracoid fat triangle replaced can be used as a basis for diagnosing scapulohumeral periarthritis, but it cannot be used as a guideline for clinical staging.

Objective To investigate the correlation between activation of toll-like receptors 3 (TLR3) signaling pathway and tumor-associated macrophage and its effect on the tumor growth. Methods The mice Lewis lung cancer cell lines 3LL and melanoma B16H10 were used to construct the subcutaneous transplantation tumor models and then they were treated with Poly-ICLC. The curative effect was observed and then the T cell and macrophage phenotypes infiltrated in local tumor were detected by flow cytometry. After the in vitro culture of mouse bone marrow-derived macrophage, the real-time PCR and western blot were applied to detect the expression of macrophage activation markers and the activation of intracellular signaling pathways. Results The survival time of mice with brown tumor treated with Poly-ICLC significantly increased and the tumor growth was inhibited. The ratio of local tumor-infiltrated Treg decreased, while the ratio of CD8

We assessed genetic and environmental effects on bone development of the hand and wrist, and on key anthropometric measures in Chinese young twins. In total, 139 monozygotic and 95 dizygotic twin pairs aged from 5 to 18 years were recruited. The twin correlations of total hand and wrist scores for monozygotic (MZ) and dizygotic (DZ) twins were 0.71 and 0.36, respectively. Bivariate model analysis showed moderate genetic correlations only for total skeletal maturity vs. weight and total skeletal maturity vs. waist circumference (r, 0.51 and 0.46, respectively). Our findings demonstrated that genetic factors played important roles in bone development of the hand and wrist in Chinese young twins, and that these genetic effects might be distinct from those influencing anthropometric measures.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.
METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.
RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).
CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

OBJECTIVETo investigate sperm DNA integrity in male infertility patients with hepatitis B virus (HBV) infection.
METHODSThis study included 90 infertile men with HBV infection (group A), 82 infertile men without HBV infection (group B) and 70 normal fertile men (group C). We detected sperm DNA integrity among the subjects, including DNA fragmentation index (DFI) and high DNA stainability (HDS), by sperm chromatin structure assay (SCSA), and compared them among the three groups.
RESULTSDFI was higher in group A ([28.17 +/- 13.06]%) than in B ([26.64 +/- 9.79]%) and C ([15.67 +/- 4.73]%), significantly higher in A and B than in C (P < 0.05) but with no significant difference between A and B (P > 0.05). HDS was higher in group A ([10.83 +/- 5.601]%) than in B ([9.04 +/- 3.48]%) and C ([8.04-2.25]%), with significant difference between A and C (P < 0.05).
CONCLUSIONSperm DNA integrity of infertile males is significantly different from that of normal fertile men, and infertility with HBV infection further impairs sperm DNA, which is manifested by abnormal sperm nuclear maturity.
