Objective To investigate the relationship between pelvic asymmetry and Crowe classification of unilateral developmental dysplasia of the hip in adults. Methods According to the inclusion criteria, 100 cases of unilateral DDH in adults were collected, including 78 females and 22 males, with an average age of 56.3 years old (range, 21-79 years). In terms of Crowe classification, there were 30 cases of Crowe typeⅠ, 24 cases of Crowe typeⅡ, 23 cases of Crowe typeⅢ, and 23 cases of CroweⅣ. The normal?side and affected?side pelvic vertical height (the distance from the highest point of the ischial tuberosity to the iliac crest peak) were measured via the radiogram of anteroposterior pelvis. Furthermore, we compared the affected?side pelvic vertical height with the normal?side and analyzed the relationship between Crowe classification and the difference in pelvic verti?cal height. Results The average pelvic vertical height was 23.38±1.46 cm in the normal?side and 22.41±1.38 cm in the affected?side. The average D?value of pelvic vertical height between two sides is 0.98 ± 0.76 cm. From Crowe typeⅠto Ⅳ, the average heights of the normal?side were 22.89±1.09 cm, 23.23±2.07 cm, 23.75±1.16 cm, 23.79±1.22 cm, while those of the affected?side were 22.70 ± 0.98 cm, 22.41 ± 1.98 cm, 22.47 ± 1.12 cm and 21.92 ± 1.32 cm. The average D?values in each group were 0.19 ± 0.37 cm, 0.82±0.43 cm, 1.28±0.32 cm, 1.87±0.59 cm. The differences between the normal?side and the affected?side in each type were statistically significant. The average D?value increased significantly with Crowe type increased, and there was a positive correla?tion between the D?value of bilateral pelvic vertical height and the degree of hip dislocation. Conclusion The pelvic asymmetry does exist in adult patients with unilateral developmental dysplasia of the hip. Moreover, the asymmetry has positive correlation with the degree of hip dislocation.

Objective To study interleukin-23 (IL-23) levels in serum and dendritic cells of acute-on-chronic liver failure (ACLF) patients with chronic hepatitis B (CHB) and to explore its relationship with the prognosis.Methods Peripheral blood mononuclear cells and serum were collected from 40 ACLF patients with CHB (including survival group 27 cases and non-survival group 13 cases) and 26 healthy controls.Monocytes were induced to immature dendritic cell in vitro and TNF-α was added to induce dendritic cell maturation.IL-23 mRNA of dendritic cells was detected by real time polymerase chain reaction (PCR), and serum IL-23 level was measured by enzyme-linked immuno sorbent assay (ELISA).Differences among the parameters with normal distribution were compared using t test, those with non-normal distribution were compared using non-parametric Mann-Whitney U-test, and the relationship between two variables was assessed by Spearman′s rank correlation.Results International normalized rate (INR) and model for end-stage liver disense (MELD) scores in non-survival group of ACLF were higher than those in survival group (INR: 2.32 vs 1.64, U=69.00, P=0.002 2;MELD:36 vs 30, U=64.50, P=0.001 4).However, there were no significant differences between two groups at gender, age, alanin aminotransferase (ALT), aspartate aminotrans ferase (AST), bilirubin, creatinine, hepatitis B virus (HBV) DNA, hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and serum IL-23.IL-23 mRNA level in dendritic cells at baseline in non-survival group of ACLF was significantly higher than that in survival group (76 vs 43, U=71.50, P=0.002 8).After treatment, serum IL-23 was significantly declined in survival group ([160±75] ng/L vs [91±49] ng/L, t=4.012, P=0.000 2), but not in non-survival group.Significant positive correlation was observed between IL-23 mRNA level in dendritic cells and MELD score at baseline (r=0.7198,P<0.01).Conclusions Persistent high serum IL-23 level suggests poor prognosis in ACLF patients with CHB.IL-23 mRNA expression in dendritic cells has good consistency with MELD score and the patients with high IL-23 mRNA expression has poor outcome.

Objective:To implement an intervention with community-dwelling middle-aged and elderly people through a new science promotion approach, and to evaluate changes in the level of bone health awareness.Methods:From April 2017 to June 2017, 200 community-dwelling middle-aged and elderly people aged 50 years and over were randomly included.They were divided into the intervention group receiving a new science promotion intervention(n=100, with 50 males and 50 females)and the control group(n=100, with 50 males and 50 females). Baseline and follow-up assessments of bone health awareness were performed before and after the one-year intervention.A questionnaire survey on preferences for different types of science promotion articles in WeChat accounts was conducted.Differences in scores for intervention effects before and after intervention were compared between the two groups.Potential influencing factors for the scale score were examined by a multi-factor analysis.Results:After one year of intervention, scores for intervention effects were higher in the intervention group than in the control group( P<0.001). In the intervention group, scores were higher after intervention than before intervention( P<0.001). In the control group, scores after follow-up were slightly higher than those at baseline(29.4±11.4 vs.27.9±10.1, P<0.001). The increase in scores before and after intervention was greater in the intervention group than in the control group( P<0.001). Baseline score, group designation, history of drinking and diabetes impacted the scores in middle-aged and elderly women, while other factors did not.Most middle-aged and older people preferred texts illustrated with pictures, and older people were more receptive to videos. Conclusions:The new science promotion method is beneficial to bone health management, can improve bone health awareness in middle-aged and elderly people.

Objective To evaluate the safety and efficacy of haploidentical hematopoietic stem cell transplan-tation(haplo-HSCT)treatment in children with hematological diseases.Methods Fifty-nine cases of less than 14 years old children with hematonosis were analyzed retrospectively,who were enrolled in the Aerospace Central Hospital from July 2012 to June 2016.And the evaluation was carried out by analyzing the success rate of implantation,occu-rrence rate of graft versus host disease(GVHD),infection rate and transplant related mortality(TRM),cumulative re-currence rate,overall survival rate(OS)and disease-free survival rate(DFS).Results In total of 59 cases,the 59 engraftments were successfully transplanted,the median time of leukocyte engraftment was 18(8-23)days,the median time of platelet engraftment was 21(11-68)days,the bone marrow was assessed 28 days after transplanta-tion,which showed that 59 patients achieved complete remission(CR)and DNA test confirmed complete donor chime-rism.With a median of follow-up time of 19(5-56)months,the cumulative recurrence rates ofⅠ,Ⅱgrade andⅢ,Ⅳ grade acute GVHD were(38.3 ± 6.3)%(23 cases)and(16.7 ± 4.8)%(10 cases),respectively,the chronic GVHD cumulative recurrence rate was(65.6 ± 7.5)%(30 cases),the cytomegalovirus(CMV)viremia cumulative recurrence rate was(45.1 ± 6.5)%(27 cases),the Epstein-Barr virus(EBV)viremia cumulative recurrence rate was(10.0 ± 3.9)%(6 cases),the viral cystitis cumulative recurrence rate was(20.0 ± 5.5)%(12 cases),the transplant related mortality was(12.8 ± 6.0)%,the 2-year cumulative recurrence rate of CR group was(8.0 ± 5.4)%,and that of non-remission(NR)group was(64.1 ± 11.9)%.The 2-year OS of CR group was(78.9 ± 7.5)%,the 2-year OS of NR group was(32.5 ± 12.9)%,the 2-year DFS of CR group was(79.5 ± 9.8)%,the 2 years DFS of NR group was(27.4 ± 7.9)%.Conclusions Haplo-HSCT is safe and effective in treating children with hematonosis,and haplo-HSCT has high survival rate and low recurrent,especially when transplantation is per-formed in the remission stage.But the prognosis of haplo-HSCT is poor in the refractory and relapsed patients,and to explore the preventing recurrence measures are very urgent.

Pain caused by surgery is an important clinical issue that seriously affects postoperative rehabilitation and health-related quality of life. Failure to effectively manage postoperative pain not only leads to a decrease in patient quality of life, increases medical expenses, but also has a negative impact on patient recovery. Therefore, it is of great clinical significance to address the challenges of acute postoperative pain management, find effective management strategies, and improve the quality of pain management. This article summarizes the current status of acute postoperative pain management in recent years, including the mechanism of pain occurrence, pain assessment methods, drug and non drug management strategies, and predictive factors for chronic postoperative pain. It also looks forward to future research directions and application prospects.

BACKGROUND/AIMS: To investigate the role of selected serum microRNA (miRNA) levels as potential noninvasive biomarkers for differentiating S0–S2 (early fibrosis) from S3–S4 (late fibrosis) in patients with a chronic hepatitis B virus (HBV) infection. METHODS: One hundred twenty-three treatment-naive patients with a chronic HBV infection who underwent a liver biopsy were enrolled in this study. The levels of selected miRNAs were measured using a real-time quantitative polymerase chain reaction assay. A logistic regression analysis was performed to assess factors associated with fibrosis progression. Receiver operating characteristic (ROC) curve and discriminant analyses validated these the ability of these predicted variables to discriminate S0–S2 from S3–S4. RESULTS: Serum miR-29, miR-143, miR-223, miR-21, and miR-374 levels were significantly downregulated as fibrosis progressed from S0–S2 to S3–S4 (p < 0.05), but not miR-16. The multivariate logistic regression analysis identified a panel of three miRNAs and platelets that were associated with a high diagnostic accuracy in discriminating S0–S2 from S3–S4, with an area under the curve of 0.936. CONCLUSIONS: The levels of the studied miRNAs, with the exception of miR-16, varied with fibrosis progression. A panel was identified that was capable of discriminating S0–S2 from S3–S4, indicating that serum miRNA levels could serve as a potential noninvasive biomarker of fibrosis progression.

Objective: To explore the effect of the Epstein-Barr virus (EBV) BZLF1 gene on the biological behavior of EBV-negative gas-tric cancer cells and the underlying molecular mechanism. Methods: Lentiviral overexpressing BZLF1 was used to infect AGS and HGC27 gastric cancer cell lines. And the cell proliferation, apoptosis and migration invasive ability, and expression changes of cell sig-naling pathway were detected by CCK8 assay, apoptosis detection, migration and invasion assay, as well as western blot. HGC27 cells overexpressing BZLF1 were injected into the dorsal of NOD/SCID mice to construct xenografts, and the effect of BZLF1 on tumor growth was observed. Results: The expression of BZLF1 protein was significantly up-regulated in AGS-BZLF1 and HGC27-BZLF1 infected by over-expressing BZLF1 lentivirus. The cell proliferation in vitro and the tumorigenic ability in mice were significantly increased (P<0.05). Apoptosis was inhibited by BZLF1 protein, and the apoptotic rate of AGS-BZLF1 and HGC27-BZLF1 was (2.40±0.14)% and (3.90± 0.14)%, which was significantly lower than (5.75±0.35)% and (9.70 ± 0.42)% of AGS and HGC cells (P<0.05); however, there was no sig-nificant change in cell migration and invasion ability. In-depth molecular mechanism studies found that PI3K/AKT signaling pathway was significantly activated with enhanced pAKT and pS6 expression. After blocking the PI3K/AKT signaling pathway with BEZ235 inhibi-tor, the growth of HGC27-BZLF1 and AGS-BZLF1 cells was inhibited. Conclusions: EBV BZLF1 may promote the growth of gastric cancer cells by activating the PI3K/AKT signaling pathway and targeting PI3K/AKT pathway inhibitors, and serve as a promising treatment op-tion for EBV-associated gastric carcinoma.

Objective:To assess the clinical efficacy and infection control outcomes of two-stage revision in managing periprosthetic joint infection (PJI) following primary total knee arthroplasty (TKA) utilizing either a low or high constrained prosthesis.Methods:A retrospective analysis was performed on 40 patients who underwent revision TKA in the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University from February 2019 to February 2022. According to the type of prosthesis selected in primary TKA, they were divided into low constrained prosthesis group and high constrained prosthesis group. There were 28 patients (28 knees) in the low constrained group, including 12 males and 16 females, aged 69.0(63.0, 74.0) years, with a body mass index of 25.18±0.55 kg/m 2. And there were 12 patients (12 knees) in the high-constrained group, including 5 males and 7 females, aged 66.5(65.0, 71.5) years, with a body mass index of 23.94±0.51 kg/m 2. All patients underwent two-stage revision surgery, with RHK used in 1 case and LCCK in 27 cases in the low-constrained prosthesis group. In the high-constrained prosthesis group, 3 patients were treated with RHK, 1 patient with PFC Sigma MBT, and 8 patients with LCCK. The preoperative and postoperative range of motion (ROM), Knee Society score (KSS), and postoperative infection control rate were compared between the two groups. Results:All patients were followed up. The follow-up time was 22.79±8.02 months in the low-constrained prosthesis group and 23.92±7.04 months in the high-constrained prosthesis group, with no significant difference between the two groups ( t=0.426, P=0.680). At the last follow-up, the KSS and ROM in the low-constrained prosthesis group were 77.96±9.74 and 93.48°±7.45°, respectively, significantly higher than 38.93±8.01 and 68.89°±9.44° before the operation ( P<0.05). The KSS score and ROM in the high-constrained prosthesis group were 67.83±8.31 and 80.08°±5.89° at the last follow-up, which were also significantly higher than those before operation (34.25±6.31 and 66.50°±10.48°, P<0.05). There was no significant difference in KSS and ROM between the two groups before operation ( P>0.05), but the KSS score and ROM in the low-constrained prosthesis group were significantly higher than those in the high-constrained prosthesis group at the last follow-up ( P<0.05). Bacterial culture results revealed that the primary infectious agents were coagulase-negative Staphylococcus and Staphylococcus aureus, with an overall infection control rate of 80% (32/40). The infection control rate was 89% (25/28) in the low-constrained prosthesis group and 58% (7/12) in the high-constrained prosthesis group, but the difference between the two groups was not statistically significant (χ 2=3.283, P=0.070). Conclusion:Two-stage revision effectively controls PJI, and the clinical outcomes of two-stage revision for PJI after primary TKA with a high-constrained prosthesis are inferior to those with a low-constrained prosthesis. Further exploration is needed to enhance efficacy.

Objective:To explore the application value of silent MR angiography (MRA) in imaging of brain arteriovenous malformation (BAVM) in children.Methods:A total of 20 children with BAVM confirmed by digital subtraction angiography (DSA) were retrospectively collected. All children were imaged by silent MRA and time-of-flight MRA (TOF MRA) in the same examination. The image quality of feeding artery, nidus and drainage vein of BAVM was evaluated using the four-point method. Wilcoxon rank-sum test was utilized to compare the image quality scores between silent MRA and TOF MRA. Weighted Kappa statistics used to evaluate the inter-modality agreement of silent MRA and TOF MRA with DSA in displaying of angioarchitecture characteristics and determination of Spetzler-Martin grading.Results:Among the 20 BAVMs, significant differences in image quality scores of the nidus (2.75±0.55 versus 2.20±0.70) and drainage vein (2.60±0.68 versus 2.20±0.77) were observed between silent MRA and TOF MRA ( Z=-3.05, P=0.002; Z=-2.13, P=0.033, respectively). The agreement between silent MRA and DSA was excellent in nidus size grading, deep venous drainage, associated aneurysm and SM grading (Kappa 0.91, 1.00, 0.83 and 0.93, respectively); The agreement between TOF MRA and DSA was fair to moderate (Kappa 0.46, 0.59, 0.35 and 0.47, respectively). Conclusions:Silent MRA showes better image quality compared to TOF MRA and improves the evaluation of angioarchitecture characteristics and Spetzler-Martin grading of BAVMs in children.

OBJECTIVE: To investigate the spectrum-effect relationship between the total anthraquinone extract of Cassia seeds and fluorouracil (5-Fu)-induced liver injury in mice and identify the effective components in the extract. METHODS: A mouse model of liver injury was established by intraperitoneal injection of 5-Fu, with bifendate as the positive control. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and myeloperoxidase (MPO), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) in the liver tissue were detected to investigate the effect of the total anthraquinone extract of Cassia seeds (0.4, 0.8 and 1.6 g/kg) on liver injury induced by 5-Fu. HPLC fingerprints of 10 batches of the total anthraquinone extracts were established to analyze the spectrum- effectiveness of the extract against 5- Fu- induced liver injury in mice and screen the effective components using the grey correlation method. RESULTS: The 5- Fu- treated mice showed significant differences in liver function parameters from the normal control mice (P < 0.05), suggesting successful modelling. Compared with those in the model group, serum ALT and AST activities were decreased, SOD and T- AOC activities significantly increased, and MPO level was significantly lowered in the mice treated with the total anthraquinone extract (all P < 0.05). HPLC fingerprints of the 31 components in the total anthraquinone extract of Cassia seeds showed good correlations with the potency index of 5-Fu-induced liver injury but with varying correlation strengths. The top 15 components with known correlations included aurantio-obtusina (peak 6), rhein (peak 11), emodin (peak 22), chrysophanol (peak 29) and physcion (peak 30). CONCLUSION The effective components in the total anthraquinone extract of Cassia seeds, including aurantio-obtusina, rhein, emodin, chrysophanol, and physcion, are coordinated to produce protective effects against 5-Fu-induced liver injury in mice.
