Objective To study the influences by a Cyelin-dependent kinase inhibitor Roscovitine on cell cycle in mitotic hepatoma carcinoma cell SMMC-7721. Methods Microscope,MTT, flow cytometry and R-T PCR were used to observe the effects of Roscovitine on morphology, proliferation, cell cycle, apoptosis and the mRNA expression of CDK2, Caspase-3, bcl-2 in SMMC-7721 cells. Results Roscovitine inhibited the proliferation of SMMC-7721 cells in dosage and time dependent manner and induced apoptosis. Flow cytometry showed the ratio of G0, G1 increased. R-T PCR showed that the expression of bcl-2 reduced, Caspase-3 increased. Conclusion Reseovitine can inhibit the growth, proliferation, block the cell cycle at G0/G1 and promotes apoptosis of mitotic SMMC-7721 cells, and the mechanism of apoptosis is dependent on the activity of bcl-2 and Caspase-3.

Objective To investigate the effect of small interfering RNA (siRNA) suppressing discoidin domain receptor 1 (DDR1) gene on biological behaviour of Kupffer cells (KC) in acute hepatic injury. Methods Male BALB/c mice were randomly divided into control, hepatic injury model, non-silencing siRNA and DDRlsiRNA groups. Hepatic injury model induced by intravenous injection of Con-canavalinA (ConA) 15 mg/kg, with or without hydrodynamic tail intravenous injection of naked siRNA (50 μg,2.0-2.5 mg/kg)/mouse or 1.5 ml normal saline. The expression of DDRI was assayed by West-ern blot and pro-inflammatory cytokine expression analyzed by ELISA. In the meantime, alanine amin-otransferase (ALT) and Kupffer cells'clearance to carbon granules was detected. Results The expres-sion of DDR1 obviously increasod at 6 h after hepatic injury, roached peak at 24 h and began to decrease at 48 h. Pretreatment with DDRisiRNA could obviously inhibit the expression of DDR1 and abrogate the high levels of ALT, expressions of TNF-α and IL-1β as well as phagocytosis of Kupffer cells. Conclu-sions Inhibition of discoidin domain receptor 1 by in vivo delivery of siRNA attenuates ConA-induced hepatic injury. Possible mechanism is that the inhibition of activity of KC inhibits the expression of pro-in-flammatory cytokines and thus alleviates hepatic injury.

OBJECTIVETo appraise the significance of extravascular lung water index (EVLWI), pulmonary vascular permeability index (PVPI), and intrathoracic blood volume index (ITBVI) in the differential diagnosis of the type of burn-induced pulmonary edema.

METHODSThe clinical data of 38 patients, with severe burn hospitalized in our burn ICU from December 2011 to September 2014 suffering from the complication of pulmonary edema within one week post burn and treated with mechanical ventilation accompanied by pulse contour cardiac output monitoring, were retrospectively analyzed. The patients were divided into lung injury group ( L, n = 17) and hydrostatic group (H, n = 21) according to the diagnosis of pulmonary edema. EVLWI, PVPI, ITBVI, oxygenation index, and lung injury score ( LIS) were compared between two groups, and the correlations among the former four indexes and the correlations between each of the former three indexes and types of pulmonary edema were analyzed. Data were processed with t test, chi-square test, Mann-Whitney U test, Pearson correlation test, and accuracy test [receiver operating characteristic (ROC) curve].

RESULTSThere was no statistically significant difference in EVLWI between group L and group H, respectively (12.9 ± 3.1) and (12.1 ± 2.1) mL/kg, U = 159.5, P > 0.05. The PVPI and LIS of patients in group L were respectively 2.6 ± 0.5 and (2.1 ± 0.6) points, and they were significantly higher than those in group H [1.4 ± 0.3 and (1.0 ± 0.6) points, with U values respectively 4.5 and 36.5, P values below 0.01]. The ITBVI and oxygenation index of patients in group L were respectively (911 197) mL/m2 and (136 ± 69) mmHg (1 mmHg = 0.133 kPa), which were significantly lower than those in group H [(1,305 ± 168) mL/m2 and (212 ± 60) mmHg, with U values respectively 21.5 and 70.5, P values below 0.01]. In group L, there was obviously positive correlation between EVLWI and PVPI, or EVLWI and ITBVI (with r values respectively 0.553 and 0.807, P < 0.05 or P < 0.01), and there was obviously negative correlation between oxygenation index and EVLWI, or oxygenation index and PVPI (with r values respectively -0.674 and -0.817, P values below 0.01). In group H, there was obviously positive correlation between EVLWI and ITBVI (r = 0.751, P < 0.01) but no obvious correlation between EVLWI and PVPI, oxygenation index and EVLWI, or oxygenation index and PVPI (with r values respectively -0.275, 0.197, and 0:062, P values above 0.05). The total area under ROC curve of PVPI value for differentiating the type of pulmonary edema was 0.987 [with 95% confidence interval (CI) 0.962-1.013, P < 0.01], and 1.9 was the cutoff value with sensitivity of 94.1% and specificity of 95.2% . The total area under ROC curve of ITBVI value for differentiating the type of pulmonary edema was 0.940 (with 95% CI 0.860-1.020, P < 0.01), and 1,077. 5 mL/m2 was the cutoff value with sensitivity of 95.2% and specificity of 88.2%.

CONCLUSIONSEVLWI, PVPI, and ITBVI have an important significance in the differential diagnosis of the type of burn-induced pulmonary edema, and they may be helpful in the early diagnosis and management of burn-induced pulmonary edema.

ObjectiveTo explore the effect of exercise on the postural control and muscular function around the ankle in patients with functional ankle instability (FAI) with meta-analysis. MethodsRandomized controlled trials about therapeutic exercise for FAI published before December, 2021 were searched from PubMed, EBSCO, SPORTdiscus, Medline, Science Direct, Springlink, Web of Science, Embase CNKI, VIP and Wanfang Data. The quality and evidence grades of the researches were evaluated by two researchers, and the outcomes were analyzed with RevMan 5.4. ResultsFourteen randomized controlled trials were finally included, involving 434 subjects. Compared with no exercise intervention, therapeutic exercise might significantly improve the movement of center of pressure whether with eye-open or eye-closed (eye-open, SMD = -0.28, 95%CI -0.46 to -0.09, P = 0.003; eye-closed, SMD = -0.24, 95%CI -0.40 to -0.09, P = 0.001); while therapeutic exercise might also enhance the activation of the peroneus longus before dynamic task (SMD = 0.38, 95%CI 0.05 to 0.71, P = 0.03), and activation of the peroneus longus (SMD = 0.53, 95%CI 0.16 to 0.90, P = 0.005) and tibialis anterior (SMD = 0.47, 95%CI 0.10 to 0.84, P = 0.01) after dynamic task. There was neither significant difference in the activation of the tibialis anterior (SMD = 0.48, 95%CI -0.14 to 1.11, P = 0.13), nor the peak torque ratio of eversion to inversion isokinetic strength (SMD = -0.15, 95%CI -0.46 to 0.16, P = 0.340) before dynamic task between the two groups. ConclusionTherapeutic exercise can decrease movement of center of pressure, enable anticipatory contraction of peroneus longus before dynamic tasks and compensatory contraction of peroneus longus and tibialis anterior after tasks, to make it easier to deal with external interference, maintain articular stability and prevent re-injury.

ObjectiveTo systematically analyze the effect of therapeutic exercise on neck function and quality of life in patients with neck pain and forward head posture. MethodsRandomized controlled trials about the effects of exercise training on forward head posture and neck pain were searched from PubMed, Web of science, Embase, Medline, Science Direct, EBSCO, Springlink, CNKI, VIP, and Wanfang Data from database establishment to April, 2022. The literature was screened by two researchers independently. Cochrane bias risk assessment tool and Physiotherapy Evidence Database Scale were used to evaluate the quality of the included articles. Revman 5.4 software was used for meta-analysis. ResultsA total of 416 patients from eleven literatures were included. Level 1a evidence indicated scapula stability training could effectively improve cranial vertebral angle (MD = 3.62, 95%CI 2.41 to 4.83, P < 0.001), and relieve pain (MD = 1.32, 95%CI 0.18 to 2.46, P = 0.02). Level 1b evidence indicated scapula stability training could reduce functional disability (MD = -0.92, 95%CI -1.11 to -0.74, P < 0.001). Level 1b evidence indicated deep cervical flexor training could improve cranial vertebral angle (MD = -0.83, 95%CI -1.56 to -0.10, P = 0.03), relieve pain (MD = 0.93, 95%CI 0.54 to 1.32, P < 0.001), and improve neck functional disability (MD = 2.17, 95%CI 1.39 to 2.95, P < 0.001). ConclusionScapula stability training and deep cervical flexor training can effectively improve cranial vertebral angle, relieve neck pain, and improve neck function.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.
