RESUMEN
BACKGROUND:Red light therapy has the non-invasive and cost-effective characteristics,and is widely used in various acute and chronic pains in clinic.However,currently,the phototherapy equipment used in clinic is expensive and has certain site limitations,so it is necessary to explore more convenient and economical phototherapy applications. OBJECTIVE:To observe the clinical efficacy of a self-developed photon cervical vertebra massage instrument for chronic neck pain. METHODS:From November 2022 to February 2023,24 patients with chronic neck pain were recruited from the Department of Rehabilitation Medicine,Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine,including 18 females and 6 males,with a mean age of(29.67±6.40)years.The body mass index was(21.39±3.52)kg/m2.Photon cervical vertebra massage instrument was used twice a day for 20 minutes each time for four weeks.The changes in visual analog scale score,pressure pain threshold,neck active activity,neck disability index,and Pittsburgh sleep quality index were observed before,after 2 and 4 weeks of treatment. RESULTS AND CONCLUSION:(1)Compared with before treatment,after four weeks of treatment,visual analog scale score,pressure pain threshold,neck disability index,and Pittsburgh sleep quality index were all improved(P<0.05),while some cervical motion(extension,left and right rotation)improved(P<0.05)after 4 weeks of treatment.(2)Bilateral visual analog scale scores,left trapezius muscle pressure pain threshold,C5C6 pressure pain threshold,and neck disability index improved after 2 weeks of treatment(P<0.05).(3)It is indicated that the application of photon cervical vertebra massage instrument can improve the pain score,muscle tenderness,sleep quality,functional level,and partial active activity of patients with chronic neck pain in a short period,and is a convenient,effective,and safe treatment method.
RESUMEN
BACKGROUND:The study of the lumbar spine and pelvis in patients with Lenke type 5 lordosis is limited to the coronal and sagittal planes,and the three-dimensional relationship between the scoliosis and the pelvis has not yet been clarified. OBJECTIVE:To analyze the effect of lumbar scoliosis on the pelvis in patients with Lenke type 5 lordosis and to study the correlation between the lumbar spine and the three-dimensional spatial position of the pelvis. METHODS:Imaging data of 60 patients with Lenke type 5 lordosis scoliosis admitted to the 3D Printing Reception Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2019 to September 2023 were retrospectively analyzed,including Cobb angle,coronal pelvic tilt,lumbar lordosis,left and right pelvic hip width ratio(sacroiliac-anterior superior iliac spine),spinal rotation angle,pelvic tilt,sacral slope,pelvic incidence,coronal deformity angular ratio,sagittal deformity angular ratio,C7 plumb line-center sacral vertical line,apical vertebral translation,and coronal sacral inclination.The information was summarized as a database.SPSS 22.0 software was used to analyze the data related to the lumbar spine and pelvis of the patients with Lenke type 5 primary lumbar curvature adolescent idiopathic scoliosis using Spearman's correlation analysis and linear regression. RESULTS AND CONCLUSION:(1)Cobb angle was highly positively correlated with coronal deformity angular ratio,apical vertebral translation,and spinal rotation angle(r=0.91,r=0.841,r=0.736).(2)Coronal deformity angular ratio was highly positively correlated with apical vertebral translation(r=0.737),moderately positively correlated with C7 plumb line-center sacral vertical line(r=0.514),and moderately negatively correlated with sagittal deformity angular ratio(r=-0.595).(3)There was a high positive correlation between lumbar lordosis and sagittal deformity angular ratio(r=0.942)and a moderate negative correlation with coronal deformity angular ratio(r=-0.554).(4)There was a moderate positive correlation between Cobb angle with coronal pelvic tilt and coronal sacral inclination(r=0.522,r=0.534)and a moderate positive correlation between C7 plumb line-center sacral vertical line and coronal pelvic tilt(r=0.507).Apical vertebral translation with coronal pelvic tilt and coronal sacral inclination showed a moderate positive correlation(r=0.507,r=0.506).Lumbar lordosis with sacral slope and pelvic incidence showed a moderate positive correlation(r=0.512,r=0.538).Sagittal deformity angular ratio was moderately positively correlated with sacral slope and pelvic incidence(r=0.614,r=0.621).(5)Studies have found that the relative position of the lumbar spine and the pelvis is closely related in the horizontal,sagittal and coronal planes.When the lumbar spine affects scoliosis and is rotated,the relative position of the pelvis will also change to compensate,which indicates that while correcting scoliosis,the correction of the pelvis cannot be ignored.
RESUMEN
ObjectiveTo investigate the in-brace and short-term correction of 3D-printed scoliosis orthoses. MethodsFrom July to December 2021, 36 patients with adolescent idiopathic scoliosis from Ninth People's Hospital, Shanghai Jiaotong University School of Medicine were selected to complete full-length radiographs of the spine before and immediately after wearing the orthosis. They wore the orthosis more than 20 hours a day, and took radiographs six months later. Cobb angle was calculated. They were assessed with Chinese version of the Scoliosis Research Society's outcomes instrument 22 (SRS-22) before wearing and six months follow-up. ResultsThe mean Cobb angle was (22.10±6.29)° before wearing, and it was (7.85±10.90)° immediately after wearing (t = 4.775, P < 0.01) and (14.33±0.74)° six months follow-up (t = 4.189, P < 0.01). The score of functional status of SRS-22 increased six months follow-up (Z = -2.676, P < 0.01). The Cobb angle immediately after wearing correlated with the Cobb angle six months follow-up (r = 0.826, P < 0.05). Conclusion3D-printed scoliosis orthoses can correct the scoliosis satisfactorily, in-brace and in short-term.

Objective:To evaluate the role of Jumonji domain-containing 3 (JMJD3) in cisplatin-induced renal fibrosis following acute kidney injury in mice.Methods:Forty-eight healthy C57BL/6 male mice, aged 8-10 weeks, weighing 20-30 g, were divided into 4 groups ( n=12 each) using a random number table method: control group (group CON), control plus JMJD3 inhibitor group (group CON-A), cisplatin group (group CIS), and cisplatin plus JMJD3 inhibitor group (group CIS-A). In group CIS and group CIS-A, cisplatin was intraperitoneally administered on 1st and 14th days, respectively, to develop a renal fibrosis model in mice with acute kidney injury, and the JMJD3 inhibitor GSKJ4 10 mg/kg and equal volume of PBS were intraperitoneally injected on 4th day, respectively, once every 3 days, 6 injections in total.The equal volume of PBS and GSKJ4 10 mg/kg were intraperitoneally injected at the corresponding time points in group CON and group CON-A, respectively.Six mice in each group were selected, and orbital blood samples were collected on 3rd day after the first injection of cisplatin to determine the concentrations of serum creatinine (Cr) and blood urea nitrogen (BUN), then the animals were sacrificed, and kidney tissues were obtained for microscopic examination of pathological changes after HE and PAS staining (with a light microscope), and the damage to kidneys was assessed and scored.Six mice were sacrificed on 28th day after the first injection of cisplatin, and kidney tissues were removed for determination of the area of renal fibrosis ( via Sirius red and Masson staining), expression of fibronectin (Fn), collagen type Ⅰ (Col Ⅰ) and α-smooth muscle actin (α-SMA) (by immunofluorescence), F4/80 + cell and CD3 + cell count (using immunohistochemical method), and expression of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), CXC chemokine ligand 16 (CXCL16), and monocyte chemoattractant protein1 (MCP-1) mRNA (by real-time polymerase chain reaction). Results:Compared with group CON, the serum BUN and Cr concentrations, renal injury scores, and area of renal fibrosis were significantly increased, the expression of Fn, Col Ⅰ and α-SMA was up-regulated, the F4/80 + cell and CD3 + cell count was increased, and the expression of IL-6, CXCL16, TNF-α and MCP-1 mRNA was up-regulated in group CIS ( P<0.05), and no significant change was found in the parameters mentioned above in group CON-A ( P>0.05). Compared with group CON-A, the serum BUN and Cr concentrations, renal injury scores, and area of renal fibrosis were significantly increased, the expression of Fn, Col Ⅰ and α-SMA was up-regulated, the F4/80 + cell and CD3 + cell count was increased, and the expression of IL-6, CXCL16, TNF-α and MCP-1 mRNA was up-regulated in group CIS-A ( P<0.05). Compared with group CIS, the serum BUN and Cr concentrations, renal injury scores, and area of renal fibrosis were significantly decreased, the expression of Fn, Col Ⅰ and α-SMA was down-regulated, the F4/80 + cell and CD3 + cell count was decreased, and the expression of IL-6, CXCL16, TNF-α and MCP-1 mRNA was down-regulated in group CIS-A ( P<0.05). Conclusions:JMJD3 is involved in the process of renal fibrosis following acute kidney injury in mice, and the mechanism may be related to promotion of inflammatory responses.

Conclusion:Activation of natural killer T cells is involved in the process of renal fibrosis in mice with AKI, and the mechanism may be related to promoting the release of Th2 cytokines and M2 polarization of macrophages.
RESUMEN
The COVID-19 pandemic is a widespread and deadly public health crisis. The pathogen SARS-CoV-2 replicates in the lower respiratory tract and causes fatal pneumonia. Although tremendous efforts have been put into investigating the pathogeny of SARS-CoV-2, the underlying mechanism of how SARS-CoV-2 interacts with its host is largely unexplored. Here, by comparing the genomic sequences of SARS-CoV-2 and human, we identified five fully conserved elements in SARS-CoV-2 genome, which were termed as "human identical sequences (HIS)". HIS are also recognized in both SARS-CoV and MERS-CoV genome. Meanwhile, HIS-SARS-CoV-2 are highly conserved in the primate. Mechanically, HIS-SARS-CoV-2, behaving as virus-derived miRNAs, directly target to the human genomic loci and further interact with host enhancers to activate the expression of adjacent and distant genes, including cytokines gene and angiotensin converting enzyme II (ACE2), a well-known cell entry receptor of SARS-CoV-2, and hyaluronan synthase 2 (HAS2), which further increases hyaluronan formation. Noteworthily, hyaluronan level in plasma of COVID-19 patients is tightly correlated with severity and high risk for acute respiratory distress syndrome (ARDS) and may act as a predictor for the progression of COVID-19. HIS antagomirs, which downregulate hyaluronan level effectively, and 4-Methylumbelliferone (MU), an inhibitor of hyaluronan synthesis, are potential drugs to relieve the ARDS related ground-glass pattern in lung for COVID-19 treatment. Our results revealed that unprecedented HIS elements of SARS-CoV-2 contribute to the cytokine storm and ARDS in COVID-19 patients. Thus, blocking HIS-involved activating processes or hyaluronan synthesis directly by 4-MU may be effective strategies to alleviate COVID-19 progression.

RESUMEN
Objective To discuss the clinical value of interventional management before surgical therapy for massive gastrointestinal hemorrhage, and to compare the clinical efficacy and re-bleeding rate between hypophysin infusion group and embolization group. Methods During the period of June 1998-Apr.2009, 31 patients with massive gastrointestinal hemorrhage in our institution underwent preoperative interventional managements before they received surgical treatment. According to DSA manifestations, the patients underwent trunsarterial hypophysin infusion or transcatheter embolization as interventional management. The clinical efficacy of interventional procedures and its influence on the surgery were evaluated, and the hemostasis rate and re-bleeding rate were compared the two kind of intervention managements. The numeration data were analyzed with Fisher's exact test, and the SPSS 11.0 was used as statistical software. Results The interventional managements were successfully performed in all the 31patients, with a total hemostasis rate of 83.9% (26/31) and a total re-bleeding rate 30.7% (8/26). The hemostasis rate and re-bleeding rate of hypephysin infusion group and embolization group were 69.2% (9/13), 94.4% (17/18) and 44.4% (4/9), 23.7% (4/17), respectively. All the 31 patients received surgery after interventional therapy, of which selective operation was carried out in 20. Neither surgery-related or intervention-related serious complications nor death occurred. Conclusion Preoperative interventional managements can provide patients with massive gastrointestinal hemorrhage with valuable chance of a successful surgery, enable the physician to take a selective operation to replace an emergency one, as a result, the surgical risk will be greatly reduced. Therefore, it is worth popularizing the preoperative interventional managements in clinical practice.
