OBJECTIVE:
To explore the displacement and pressure distribution of American Chiropractic in a model of third lumbar syndrome based on finite element analysis.
METHODS:
On March 2021, CT and MRI images of a 23-year-old male patient with right third lumbar syndrome were selected. A 3D stl model was established using Mimics and CATIA, and the data was imported into Hypermesh, Abaqus & ANSYS. The elastic modulus and Poisson's ratio of the affected side material were adjusted to establish its finite element model. Based on the comparison of the operating positions and routines of the American Chiropractic and the lumbar spine oblique pull method, but with differences in the focus and direction of force, the experimental group simulated the American Chiropractic with the healthy side (left side) lying position of the model. The upper endplate of L3 and the lower part below L3 twisted accordingly with the body position, we applied a vertical forward thrust of 246 N to the plane formed by the L4, L5 spinous processes and L4 upper articular processes;The control group simulates the oblique pull method of the lumbar spine, requiring the model to lie on the healthy side (left side), fix the upper endplate of L4, and perform a horizontal rotation along the longitudinal axis of L3 vertebral body. At this time, the contact force in the upward direction is also set to 246 N. Compare the displacement and stress differences between the L1-L5 intervertebral bodies, intervertebral discs, articular processes, and transverse process muscles in two intervention models.
RESULTS:
① Under safe load conditions, a test force of 246 N was applied to the model, and the maximum vertebral displacement occurred on the right side of the L3 vertebral body (1.197 mm) after manual intervention in the control group. The vertebral displacement between L1-L5 induced by manual intervention in the experimental group was smaller than that of the control group's manual intervention (P<0.05). ② The maximum vertebral body stress occurred on the right side of the L3 vertebral body after manual intervention in the control group (98.425 MPa). The stress on each vertebral body formed by the experimental group's manual intervention was lower than that of the control group's manual intervention (P<0.05). ③The maximum intervertebral disc stress occurred on the right side of the L2,3 intervertebral disc (6.282 MPa) after manual intervention in the control group. ④ The maximum joint process stress occurred on the right side of the L4 upper joint process after manual intervention in the experimental group (1.587 MPa). The joint process stress on the left side below L1 and the left side above and below L2 induced by manual intervention in the experimental group was lower than that of the control group (P<0.05). ⑤The maximum stress on the intertransverse process muscle was observed at the right lateral L3 process end (31.960 MPa) of L3,4 in the control group after manual intervention. The stress on the L2,3 and L4,5 segments of the intertransverse process muscle induced by manual intervention in the experimental group was lower than that of the control group's manual intervention (P<0.05).
CONCLUSION
The mechanical feedback of the L1-L5 vertebral body, the lower left side of the articular process L1, the upper and lower left side of the articular process L2, and the L2,3 and L4,5 segments of the transverse process muscle in the model indicates that performing American Chiropractic for the treatment of third lumbar transverse process syndrome can accurately hit the target pain point and allow the patient's tissue to form a low stress and low tension state after manual operation, thereby reducing the possibility of tissue damage caused by hypertonia after intervertebral joint movement, making it relatively safe. The application of American Chiropractic will be a new supplement to the traditional treatment plan for third lumbar transverse process syndrome.

OBJECTIVE:
To observe the clinical symptoms and MRI outcomes of patients with ruptured lumbar disc herniation(LDH) through a multicenter randomized controlled study, and to evaluate the clinical efficacy and safety of Yiqi Huoxue formula() in the treatment of this disease.
METHODS:
A total of 160 outpatients and inpatients with ruptured LDH admitted to 4 medical centers from January 2023 to June 2023 were selected and randomly divided into the Yiqi Huoxue formula group and the control group, with 80 patients in each group. In the Yiqi Huoxue formula group, there were 43 males and 37 females, with an age of (41.03±9.56) years and a disease duration of (10.45±25.37) days, and the patients were treated with Yiqi Huoxue formula. In the control group, there were 34 males and 46 females, with an age of (42.14±8.73) years and a disease duration of (11.31±21.14) days;during the acute phase, patients in this group could take celecoxib capsules orally, and methylcobalamin orally at the same time. The Japanese Orthopaedic Association (JOA) score, Oswestry disability index (ODI), changes in the volume of herniated disc tissue on MRI, herniation rate, and absorption rate were recorded at the time of enrollment and during follow-ups at the 3rd, 6th, and 12th month after treatment.
RESULTS:
A total of 156 patients completed the clinical follow-up, and 4 patients withdrew midway. The clinical symptoms of all patients who completed the study were relieved to varying degrees, and reabsorption of herniated disc tissue was observed in all patients in the Yiqi Huoxue formula group after treatment. For the JOA score:in the Yiqi Huoxue formula group, it was (10.73±2.76) points before treatment and (24.65±2.19) points at the 12th month after treatment;in the control group, it was (11.01±1.20) points before treatment and (17.07±3.26) points at the 12th month after treatment. For the ODI score:in the Yiqi Huoxue formula group, it was (26.21±3.55) points before treatment and (5.65±2.19) points at the 12th month after treatment;in the control group, it was (27.92±2.51) points before treatment and (9.09±2.15) points at the 12th month after treatment. At the 12th month after treatment, the JOA and ODI scores of both groups were better than those before treatment, and the scores of the Yiqi Huoxue formula group were better than those of the control group, with statistically significant differences (P<0.05). In terms of the herniated disc volume and herniation rate on MRI, the Yiqi Huoxue formula group was superior to the control group, with statistically significant differences(P<0.05). Reabsorption occurred in 56.96%(45/79) of patients in the Yiqi Huoxue formula group, which was significantly higher than the 37.66%(29/77) in the control group.
CONCLUSION
After treatment with Yiqi Huoxue formula, patients with ruptured LDH show significant improvement in clinical symptoms and a marked reduction in the volume of herniated discs. During the follow-up period, no obvious adverse drug reactions are observed in patients, and no recurrence of symptoms is found at the last follow-up, indicating that the formula has safe and reliable efficacy.

OBJECTIVE:
This study aimed to evaluate the association between susceptibility genes and non-alcoholic fatty liver disease (NAFLD) in children with obesity.
METHODS:
We conducted a two-step case-control study. Ninety-three participants were subjected to whole-exome sequencing (exploratory set). Differential genes identified in the small sample were validated in 1,022 participants using multiplex polymerase chain reaction and high-throughput sequencing (validation set).
RESULTS:
In the exploratory set, 14 genes from the NAFLD-associated pathways were identified. In the validation set, after adjusting for sex, age, and body mass index, ECI2 rs2326408 (dominant model: OR = 1.33, 95% CI: 1.02-1.72; additive model: OR = 1.22, 95% CI: 1.01-1.47), C6orf201 rs659305 (dominant model: OR = 1.30, 95% CI: 1.01-1.69; additive model: OR = 1.21, 95% CI: 1.00-1.45), CALML5 rs10904516 (pre-ad dominant model: OR = 1.36, 95% CI: 1.01-1.83; adjusted dominant model: OR = 1.40, 95% CI: 1.03-1.91; and pre-ad additive model: OR = 1.26, 95% CI: 1.04-1.66) polymorphisms were significantly associated with NAFLD in children with obesity ( P < 0.05). Interaction analysis revealed that the gene-gene interaction model of CALML5 rs10904516, COX11 rs17209882, and SCD5 rs3733228 was optional ( P < 0.05), demonstrating a negative interaction between the three genes.
CONCLUSION
In the Chinese population, the CALML5 rs10904516, C6orf201 rs659305, and ECI2 rs2326408 variants could be genetic markers for NAFLD susceptibility.

Objective:To analyze the treatment efficacy, safety and dose parameters of optimized hippocampus-avoidance prophylactic cranial irradiation (HA-PCI) in limited-stage small cell lung cancer (LS-SCLC) and explore the corresponding dosimetric parameters under the condition of narrowing the hippocampus avoidance region as hippocampus region plus 2 mm in three dimensions.Methods:Clinical data of patients with LS-SCLC receiving HA-PCI (hippocampus avoidance region defined as hippocampus region plus 2 mm in three dimensions) in Cancer Hospital Chinese Academy of Medical Sciences from August 2014 to June 2020 were retrospectively analyzed. Dose parameters of HA-PCI and adverse events were analyzed using descriptive statistics analysis. Changes of neurocognitive function, such as mini-mental state examination (MMSE) and Hopkins verbal learning test-revised (HVLT-R) scores, were evaluated by analysis of variance and Kruskal-Wallis H test. Overall survival (OS), progression-free survival (PFS) and intracranial PFS (iPFS) were calculated using Kaplan-Meier method. The cumulative incidence of local-regional recurrence (LRR), extracranial distant metastases (EDM), and locoregional recurrence (LR) were investigated under competing risk analysis. Results:A total of 112 patients were included, the median follow-up time was 50 months (95% CI: 45.61-54.38). The median volume of hippocampus was 4.85 ml (range: 2.65-8.34 ml), with the average dose ≤9 Gy in 106 patients (94.6%), ≤8 Gy in 92 patients (82.1%). The median volume of hippocampus avoidance area was 15.00 ml (range: 8.61-28.06 ml), with the average dose ≤12 Gy in 109 patients (97.3%), ≤10 Gy in 101 patients (90.2%). The 2-year cumulative LRR, EDM, LR rates were 16.9%, 23.2% and 28.5%, respectively. The 5-year cumulative LRR, EDM, LR rates were 23.2%, 26.9% and 33.3%, respectively. The 2-year iPFS, PFS and OS rates were 66.1% (95% CI: 57.9%-75.4%), 53.6% (95% CI: 45.1%-63.7%) and 80.4% (95% CI: 73.3%-88.1%), respectively. The most common grade I-Ⅱ adverse events were nausea (33.9%) and dizziness (31.3%), and only 1 patient developed grade Ⅲ nausea and dizziness. MMSE ( n=57) and HVLT-R tests ( n=56) showed no significant decline. Conclusions:Optimized HA-PCI can achieve similar dose limitation with favorable efficacy and light toxicity. No significant decline is observed in short-term neurocognitive function in evaluable patients.

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

ObjectiveTo observe the clinical efficacy of Tongdu Huoxue decoction in the treatment of acute lumbar disc herniation (LDH). MethodA total of 316 patients with acute LDH admitted to the orthopedic outpatient department of Hubei Provincial Hospital of Traditional Chinese Medicine and Honghu City Hospital of Traditional Chinese Medicine from January 2020 to June 2023 were randomly divided into two groups. 156 cases in the control group (two cases with stopped follow-up) were treated with meloxicam tablets, while 153 cases in the observation group (five cases with stopped follow-up) were treated with Tongdu Huoxue decoction. Both groups were treated for three months. The clinical efficacy, McGill Pain Score Scale (SF-MPQ), Oswestry Dysfunction Index (ODI) score, and the Japanese Orthopaedic Association (JOA) scores of the two groups before and after treatment were compared. The serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) of the patients before and after treatment were determined by using enzyme-linked immunosorbent assay (ELISA). The NDI-092 type electromyography-evoked potential instrument was adopted to measure the motor conduction velocity and clinical efficacy of the tibial and common peroneal nerves in patients of the two groups before and after treatment, and the clinical safety of the two groups of patients was compared. ResultAfter treatment, the total effective rate in the observation group was 95.4% (146/153), significantly higher than that in the control group of 76.3% (119/156) (χ2 =23.18, P<0.05). After treatment, both groups showed significant reductions in SF-MPQ and ODI scores, as well as the levels of IL-1β, IL-6, and TNF-α (P<0.05), with the observation group showing a more significant reduction (P<0.05). Both groups showed a significant increase in JOA scores and motor conduction velocities of the tibial and common peroneal nerves after treatment (P<0.05), with the observation group showing a more significant increase (P<0.05). ConclusionTongdu Huoxue decoction can alleviate lumbar and leg pain in acute LDH, improve lumbar spine function, and suppress inflammatory reactions. It is highly safe and is worthy of clinical promotion.

OBJECTIVE To investigate the effect of pachymic acid (PA) on renal function and fibrosis in chronic renal failure (CRF) rats and its potential mechanism based on the Ras homolog gene family member A (RhoA)/Rho-associated coiled-coil forming protein kinase (ROCK) signaling pathway. METHODS Using male SD rats as subjects, the CRF model was established by 5/6 nephrectomy; the successfully modeled rats were divided into model group, PA low-dose, medium-dose and high-dose groups (5, 10, 20 mg/kg PA), high-dose PA+ROCK pathway activator lysophosphatidic acid (LPA) group (20 mg/kg PA+1 mg/kg LPA), with 15 rats in each group. Another 15 rats were selected as the sham operation group with only the kidney exposed but not excised. The rats in each drug group were gavaged and/or injected with the corresponding liquid via the caudal vein, once a day, for 12 consecutive weeks. During the experiment, the general condition of rats was observed in each group. After the last administration, the serum renal function indexes (blood urea nitrogen, serum creatinine, uric acid) of rats in each group were detected, the renal histopathological changes were observed; the renal tubule injury score and the area of renal fibrosis were quantified. The levels of oxidative stress indexes [malondialdehyde (MDA), superoxide dismutase (SOD)] and inflammatory factors (tumor necrosis factor-α, interleukin-1β, interleukin-6), the positive expression rates of connective tissue growth factor (CTGF) and collagen Ⅰ were detected as well as the expression levels of pathway-related proteins (RhoA, ROCK1) and fibrosis- related proteins (transforming growth factor-β1, bare corneum homologs 2, α-smooth muscle actin) were determined. RESULTS Compared with the sham operation group, the rats in model group had reduced diet, smaller body size, listless spirit and sluggish response, reduced and atrophied glomeruli, dilated renal tubules with chaotic structure, and a large number of inflammatory cells infiltrated interstitium; the serum levels of renal function indexes, renal tubule injury score, renal fibrosis area proportion, the levels of MDA and inflammatory factors, the positive expression rates of CTGF and collagen Ⅰ, and the expression levels of pathway-related proteins and fibrosis-related proteins in renal tissues were significantly increased, while SOD level was significantly decreased (P<0.05). Compared with the model group, the general condition and pathological injuries of kidney tissue of rats in PA groups were improved to varying degrees,and the above quantitative indexes were significantly improved in a dose-dependent manner (P<0.05). LPA could significantly reverse the improvement effect of PA on the above indicators (P<0.05). CONCLUSIONS PA can improve renal function and alleviate renal fibrosis in CRF rats, which may be related to inhibiting the activation of RhoA/ROCK signaling pathway.

Objective:To observe the effect of combining robot-assisted gait training (RAGT) with task-oriented training (TOT) on the walking ability of children with dyskinetic cerebral palsy (DCP).Methods:Sixty DCP children were randomly divided into a conventional intervention group, an RAGT group, and a combined intervention group, each of 20. All of the children received conventional rehabilitation therapy, while the RAGT and combined intervention groups were additionally provided with RAGT, and RAGT combined with TOT, respectively. Before the experiment and after 12 and 24 weeks of treatment, the subjects′ walking ability was evaluated using the 10-metre walk test (10MWT), and the D energy zone (standing position) and the E energy zone (walking, running and jumping) of the Gross Motor Function Measurement-88 (GMFM-88) instrument.Results:After 12 and 24 weeks of treatment, the average 10MWT speed and D and E energy zone scores of all three groups had improved significantly. After 24 weeks the combined group′s averages on all three measures were significantly better than those of the other two groups.Conclusion:RAGT combined with TOT and conventional rehabilitation training significantly improves the walking ability of DCP children.
