Objective To explore the effect of different position replacement orders on single side effect of blue light treatment of neonatal jaundice.Methods 100 cases newborns requiring phototherapy were randomly divided into the control group and the observation group.The control group adopted conventional phototherapy position change sequence (horizontal position-lateral position-prone position),the observation group used the new position replacement order (prone position-lateral position-horizontal position).The resistance reaction of babies and treatment effect of phototherapy were observed in two groups.Results Significant difference existed in resistance reaction (cry loudly,milk refusal)and phototherapy effects between the observation group and the control group.Conclusions The position change order such as prone position-lateral position-horizontal position by neonates during phototherapy,can reduce resistance reaction and improve treatment effect.

Objective To meta-analyze the effect of mirror therapy on the lower limb motor function and ac-tivities of daily living of stroke survivors so as to evaluate its clinical efficacy. Methods Medline, PubMed, OT seeker, the Cochrane library, the Wanfang database, the VIP database and the CNKI were searched for reports of randomized and controlled trials (RCTs) of the effect of mirror therapy on the lower limb motor function and activities of daily living of stroke survivors published between December 2008 and December 2018. Strict inclusion and exclu-sion criteria were applied, and the quality of the documents was comprehensively assessed according to version 5.1.0 of the Cochrane manual. The results were analyzed using version 5.2 of the RevMan software suite. Results Four-teen trials were included. Meta-analysis showed that mirror therapy had been shown to improve the patients'scores of Fugl-Meyer assessment ( FMA ), functional ambulance category ( FAC ) and modified Barthel index ( MBI ). Conclusion Mirror therapy can improve the motor function of the affected lower extremities of stroke survivors and their ability in the activities of daily living.

Objective To study the mechanism of central nervous system (CNS) injury in chronic fluorosis and the neuroprotective effect of chondroitin sulfate (CS).Methods Forty-eight female Sprague-Dawley rats weighting 90-120 g were divided into 8 groups according to body weight by random number table,6 rats in each group:control group,drinking tap water freely;low dose and high dose fluoride groups,freely drinking tap water with fluoride content of 10 and 50 mg/L,respectively;control + normal saline (NS),low dose fluoride + NS,and high dose fluoride + NS groups,each group was fed for 180 d,and treated with intraperitoneal injection of 0.66 mg/kg NS for 5 d (once a day);low dose fluoride + CS and high dose fluoride + CS groups,each group was fed for 180 d,0.66 mg/kg CS was injected intraperitoneally for 5 d (once a day).All groups were fed standard nutritive animal feed for 185 d and dissected for brain tissue.The pathologic change was observed after hematoxylin-eosin (HE)staining;the expression levels of phosphorylated extracellular signal-regulated protein kinase 1/2 (phospho-Erk1/2)and glutamate receptors 1,2 (GluR1,GluR2) in the brain cortex were detected by immunohistochemistry;the protein levels of Erk1/2,phospho-Erk1/2,GluR1,and GluR2 in the brain cortex were detected by Western blotting.Results Brain cortex of all rats in the fluoride groups showed eosinophilic degeneration,loss and disordered arrangement of neurons,and the brain morphological changes in each fluoride + CS groups were significantly improved compared with those in the fluoride groups.Immunohistochemistry results showed that compared with the control group [(0.44 ± 0.09)％,(1.49 ± 0.05)％,(2.51 ± 0.54)％],the expression levels of phospho-Erk1/2 [(1.47 ±0.09)％,(1.03 ± 0.05)％],and GluR2 [(2.37 ± 0.06)％,(3.38 ± 0.12)％] in the low dose and high dose fluoride groups were increased,and the expression levels of GluR1 [(1.49 ± 0.02)％,(0.99 ± 0.19)％] were decreased (P ＜ 0.05).Western blotting results showed that compared with the control group (1.00 ± 0.12,1.76 ± 0.33),the protein levels of Erk1/2 (3.10 ± 0.76,1.99 ± 0.01) and phospho-Erk1/2 (3.27 ± 0.25,2.67 ± 0.05) in low dose and high dose fluoride groups were significantly increased (P ＜ 0.05);compared with low dose fluoride group,the protein levels of Erk1/2,and phospho-Erk1/2 (1.30 ± 0.31,2.20 ± 0.34) in low dose fluoride + CS group decreased significantly (P ＜0.05).Compared with control group (1.86 ± 0.47,1.17 ± 0.27),the protein levels of GluR1 (1.09 ± 0.26,0.61 ± 0.14) in low dose and high dose fluoride groups decreased significantly,while the protein level of GluR2 (1.99 ± 0.42,3.38 ±0.27) increased significantly (P ＜ 0.05);compared with low dose and high dose fluoride groups,the protein levels of GluR2 in low dose fluoride + CS and high dose fluoride + CS groups (1.53 ± 0.41,2.65 ± 0.32) decreased significantly (P ＜ 0.05).The protein level of phospho-Erk1/2 was negatively correlated with GluR1 protein level (r =-0.975,-0.991,P ＜ 0.05) in low dose and high dose fluoride groups,and it was positively correlated with the protein level of GluR2 (r =0.986,0.993,P ＜ 0.05).Conclusion The CNS injury caused by chronic fluorosis may be related to GluR1 and GluR2 activated Erk1/2 signaling pathway,and CS has certain protection to the injury.

Objective:To observe the expression levels of glial fibrillary acidic protein (GFAP), β-tubulin Ⅲ and synaptophsin, and explore the role of tripartite synapse in the mechanism of central nervous system (CNS) injury and the neuroprotective effect of chondroitin sulfate (CS).Methods:One month old clean grade, 48 female Sparague-Dawley rats and 48 male Sparague-Dawley rats, were randomly divided into 8 groups according to body weight (90 - 120 g) by random number table method, with 12 rats in each group, half male and half female. These rats were fed with water containing different concentrations of sodium fluoride (NaF) [ < 0.5 mg/L (control, CN), 10.0 mg/L (low dose fluoride, LF) and 50.0 mg/L (high dose fluoride, HF)]. Some rats were fed directly for 185 days (CN, LF and HF groups). In addition, rats of CN + normal saline (NS), LF + NS, HF + NS groups and LF + CS, HF + CS groups, were intraperitoneally injected with NS or 0.66 mg/kg CS for 5 consecutive days after 180 days of feeding. After the experiment, the pathological changes of hippocampal CA4 of brain tissue in each group were observed by hematoxylin eosin staining under light microscope, and the expression and distribution of GFAP, β-tubulin Ⅲ and synaptophsin in hippocampal CA4 of rats were detected by immunohistochemistry, the expression of GFAP, β-tubulin Ⅲ and synaptophsin at protein level in hippocampus of rats were detected by Western blotting.Results:Under light microscope, eosinophilic change, loss and irregular arrangement of neuron in the hippocampal CA4 were observed in LF, HF, LF + NS and HF + NS groups. The morphology of LF + CS and HF + CS groups was not significantly changed compared with CN group, but was significant changed compared with LF, HF, LF + NS and HF + NS groups. Immunohistochemical results showed that the rates of positive area of GFAP, β-tubulin Ⅲ and synaptophsin in female and male rats in LF and HF groups were significantly decreased than those in CN group ( P < 0.05); the positive area rates of female and male rats in LF + CS and HF + CS groups were higher than those in LF and HF groups, respectively ( P < 0.05). Western blotting results showed that the proten expression levels of GFAP, β-tubulin Ⅲ and synaptophsin of female and male rats in LF and HF groups (LF group: 0.90 ± 0.09, 0.82 ± 0.08, 1.43 ± 0.14, 0.92 ± 0.02, 1.21 ± 0.15, 0.87 ± 0.02, HF group: 0.58 ± 0.14, 0.73 ± 0.03, 0.63 ± 0.06, 0.67 ± 0.03, 0.87 ± 0.04, 0.70 ± 0.05) were lower than those in CN group (1.24 ± 0.08, 1.09 ± 0.10, 2.64 ± 0.30, 1.54 ± 0.09, 1.72 ± 0.10, 1.13 ± 0.06, P < 0.05). Conclusions:The tripartite synapse and extracellular matrix may take part in pathogenesis of the damages of CNS results from chronic fluorosis; CS may reduce the injury to a certain extent.

Background: Cervical cancer is still present a major public health problem, especially in developing countries. In International Federation of Gynaecology and Obstetrics 2018, allowing assessment of retroperitoneal lymph nodes by imaging and/or pathological findings and, if deemed metastatic, the case is designated as stage IIIC (with r and p notations). Patients with lymph node metastases have lower overall survival (OS), progression free survival (PFS), and survival after recurrence, especially those who have unresectable macroscopical positive lymph nodes. Retrospective analysis suggests that there may be a benefit to debulking macroscopic nodes that would be otherwise difficult to sterilize with standard doses of radiation therapy. However, there are no prospective study reporting that resecting macroscopic nodes before concurrent chemoradiation therapy (CCRT) would improve PFS or OS of cervical cancer and no guidelines for surgical resection of bulky lymph nodes. The CQGOG0103 study is a prospective, multicenter and randomized controlled trial (RCT) evaluating lymph node dissection on stage IIICr of cervical cancer. Methods Eligible patients are histologically confirmed cervical squamous cell carcinoma, adenocarcinoma, adeno-squamous cell carcinoma. Stage IIICr (confirmed by computed tomography [CT]/magnetic resonance imaging/positron emission tomography/CT) and the short diameter of image-positive lymph node ≥15 mm. 452 patients will be equally randomized to receive either CCRT (pelvic external-beam radiotherapy [EBRT]/extended-field EBRT + cisplatin [40 mg/m2] or carboplatin [the area under curve=2] every week for 5 cycles + brachytherapy) or open/minimally invasive pelvic and para-aortic lymph node dissection followed by CCRT. Randomization is stratified by status of para-aortic lymph node. The primary endpoint is PFS. Secondary endpoints are OS and surgical complications. A total of 452 patients will be enrolled from multiple hospitals in China within 4 years and followed up for 5 years.

Chronic Urticaria(CU)is a common skin disease involving autoimmunity and allergies,which brings a heavy burden to patients and society.The theory of traditional Chinese medicine"the Lung is combined with the Large Intestine,and the symptoms of large intestine can be reflected from the skin"has long shown that there is a close physiological and pathological relationship between the function of the Large Intestine and the skin.With the modern advancement of the"gut-skin axis"theory,the correlation between gut microbiome and CU has gradually become an emerging focus of research.Adjusting the imbalance of gut microbiome would be a new trend in the clinical treatment of CU.Acupuncture has a beneficial effect of regulating the gut microbiome,and the definite curative effect on CU.Therefore,this article summarized the research progress between the gut microbiome and CU in recent years,in order to discuss the feasibility of acupuncture to treat CU by regulating the gut microbiome,and provide a new idea for the mechanism research of acupuncture in the treatment of CU from the perspective of"treating skin from intestine".

OBJECTIVE：To investigate the anti-apoptotic effect of curcumin on H 2O2-induced H 9c2 cardiomyocyte injury and the regulation of NF-κB signaling pathway. METHODS：H9c2 cardiomyocyte were randomly divided into normal control group ， injury model group ，curcumin low-dose ，medium-dose and high-dose groups （25，50，100 μmol/L）. Normal control group didn ’t received any intervention. The cells in injury model group were induced with 50 μmol/L H2O2 for 12 h to establish the injury model. The cells in curcumin groups were treated with relevant concentration of drugs for 24 h，and then induced with 50 μmol/L H2O2 for 12 h. After cultured for 24 h，survival rate and apoptotic rate of cells were measured by MTT method and TUNEL method ；SOD activity and MDA content were determined by WTS- 8 assay and color test ；relative fluorescence intensity of LC 3 positive expression was detected by immunofluorescence method ；mRNA expression of NF-κB p65 in cells was detected by real-time PCR ； Western blotting assay was used to detect the protein expression of NF-κB p65 and p-NF-κB p65 in cells. RESULTS ：Compared with normal control group ，survival rate and SOD activity were decreased significantly in injury model group ，while apoptotic rate ， MDA content ，relative fluorescence intensity of LC 3 positive expression ，mRNA expression of NF-κB，protein expression of NF-κ B p 65 and p-NF-κB p65 as well as p-NF-κB/NF-κB were increased significantly（P＜0.05）. Compared with injury model group ， survival rates and SOD activities were increased significantly in curcumin groups ，while apoptotic rates ，MDA contents ，relative fluorescence intensities of LC 3 positive expression ，mRNA expression of LC 3 positive cells ，protein expression of NF-κB p65 and p-NF-κ B p65 as well as p-NF-κ B p65/NF-κ B p65 were decreased significantly （P＜0.05）. CONCLUSIONS ：Curcumin can increase the survival rate of H 2O2-induced H 9c2 cardiomyocyte injury ，decrease its apoptotic rate ，increase SOD activity and decrease MDA content in cardiomyocytes. Above effects may be related to the regulation of NF-κB signaling pathway.

Objective:To investigate the clinical characteristics and prognostic factors of 2019 novel coronavirus (2019-nCoV) Omicron variant infected cases.Methods:A total of 987 coronavirus disease 2019 (COVID-19) adult imported cases admitted to Shanghai Public Health Clinical Center, Fudan University from July 1, 2021 to January 6, 2022 were recruited. The cases were divided into Omicron group (193 cases) and non-Omicron group (794 cases) according to the genotype of the virus. The clinical data, imaging examination and laboratory results of two groups were collected and compared. Chi-square test and Mann-Whitney U test were used as statistical methods. Multiple linear regression analysis was used for multiple linear regression analysis. Results:The majority of patients in Omicron group were 18 to 30 years old, accounting for 51.3%(99/193), which was higher than 31.4%(249/794) in non-Omicron group. The difference was statistically significant ( χ2=52.75, P<0.001). The proportion of mild cases in Omicron group was 88.6%(171/193), which was higher than 81.6%(648/794) in non-Omicron group. The difference was statistically significant ( χ2=5.37, P=0.021). Cases with symptoms were more common in Omicron group than those in non-Omicron group (60.1%(116/193) vs 29.1%(231/794)), and the difference was statistically significant ( χ2=65.49, P<0.001), with the main clinical manifestations of sore/itchy throat, fever and cough/expectoration. The proportion of cases with pulmonary computed tomography (CT) imaging manifestations at admission in Omicron group was 13.0%(25/193), which was lower than that in non-Omicron group (215/794, 27.1%). The difference was statistically significant ( χ2=16.83, P<0.001). The proportion of cases with 2019-nCoV IgG positive at admission was 47.7%(92/193) in Omicron group, which was lower than 61.1%(485/794) in non-Omicron group, and the difference was statistically significant ( χ2=11.51, P<0.001). The hospitalization time of Omicron group was 20.0 (16.0, 23.0) d, which was longer than that of non-Omicron group (14.0 (10.0, 22.0) d), and the difference was statistically significant ( Z=-7.42, P<0.001). Multiple linear regression analysis showed that the time of hospitalization of cases with 2019-nCoV IgG positive at admission was shorter, while that of the cases with fever in Omicron group was longer (both P<0.050). Conclusions:The main clinical characteristics of cases with Omicron variant are fever and upper respiratory symptoms. Their pulmonary CT imaging manifestations are less, and the time of hospitalization is slightly longer. The time of hospitalization and the virus clearance time in Omicron variant infected cases with 2019-nCoV IgG positive at admission and not presented with fever are both shorter.

Objective: To observe the effect of Tai Chi combined with conventional western medicine therapy for elderly patients with type2 diabetes mellitus. Methods: According to randomized controlled design, 108 patients were divided into two groups ,with 54 in each group. Patients in control group were treated with conventional western medicine therapy and regular walk (three times per week), while the patients in the observation group were treated with conventional western medicine therapy and Tai Chi (three times per week), both groups were treated for 12 weeks.
