AIM: To study the protective effect of fenofibrate on diabetic retinal neurodegeneration and observe its effect on miR-26a-5p and its target gene PTEN in the retinal of diabetic mice.METHODS: Diabetic mice models were established and they were gavaged by fenofibrate. H& E staining and transmission electron microscopy were used to observe the impairments of retinal neurons. Real-time PCR was used to examine the expression of miR-26a-5p, and Western blotting was employed to measure the expression of phosphatase and tensin homologue(PTEN)in the retina of diabetic mice. The expression level of nuclear factor-κB(NF-κB), interleukin-1β(IL-1β)and the morphology of neural tissues were observed.RESULTS: When compared with the diabetic mice, fenofibrate significantly attenuated the damage to retinal ganglion cells and the atrophy of retinal nerve fiber layer. While the level of miR-26a-5p was increased and the levels of PTEN and inflammatory mediators were significantly decreased in the retina of fenofibrate treated diabetic mice, with significant statistical significance(P<0.05).CONCLUSIONS: Fenofibrate protects against diabetic retinal neurodegeneration by upregulating miR-26a-5p and inhibiting PTEN, attenuating the inflammatory response and alleviating retinal cell injury.

Objective:To learn about the infection status of Anisakis larvae in the major economic marine products in the Yellow Sea and Bohai Sea, and provide baseline data for systematic monitoring of Anisakis and prevention and control of related diseases. Methods:From April 2016 to September 2020, the samples of marine products collected in the surrounding waters of 9 fishing sites in the Yellow Sea and Bohai Sea (Bohai Bay, the middle part of the Yellow Sea and Bohai Sea junction, the southern part of the Yellow Sea and Bohai Sea junction, the northern part of the Yellow Sea and the southern part of the Yellow Sea) in the coastal areas of Yantai City and Weihai City, Shandong Province were dissected and tested for worms. The infection and distribution of Anisakis larvae in different types of samples and different organs in the samples were compared, and the differences of the infection level of Anisakis larvae in marine fish among the surrounding waters of different fishing sites and different sampling sites in China were compared. At the same time, a survey on the awareness of health knowledge of anisakiasis was carried out among the residents near each fishing sites. Results:A total of 708 cases of 5 types of marine products were tested in the Yellow Sea and Bohai Sea, including 581 cases of marine fish, 22 cases of mollusks, 20 cases of echinodermata, 75 cases of crustaceans and 10 cases of shellfish. Anisakis larvae infection was detected only in marine fish (191 cases), and 4 723 Anisakis larvae were found. The infection rate was 32.87% (191/581) and the infection intensity was 24.73(4 723/191) larvae/case. They were mainly distributed in mesentery and intestinal wall (38.96%, 1 840/4 723), coelom (22.04%, 1 041/4 723) and gastric wall (17.95%, 848/4 723). The infection levels of Anisakis larvae in marine fish among the surrounding waters of different fishing sites were compared, the infection rate in the southern part of the Yellow Sea was the highest, and its infection intensity was significantly higher than that in the middle and southern part of the Yellow Sea and Bohai Sea junction ( P < 0.05). The infection levels of Anisakis larvae in marine fish among different sampling sites in China were compared, the infection rates of Zhoushan Port, the fish sold in Jinzhou, Yantai and Shantou were significantly higher than those in the Yellow Sea and Bohai Sea ( P < 0.05), and the infection rates of the fish sold in Dandong and Qingdao were significantly lower than those in the Yellow Sea and Bohai Sea ( P < 0.05). A total of 1 805 residents living near the Yellow Sea and Bohai Sea were investigated on the health knowledge of anisakiasis. Among them, 20.78% (375/1 805) residents had heard of anisakiasis, 15.73% (284/1 805) residents knew how to get it, 12.30% (222/1 805) residents knew the harm of anisakiasis to human body, and 16.68% (301/1 805) residents knew how to prevent it. Conclusions:The marine fish in the Yellow Sea and Bohai Sea are infected by the Anisakis larvae, and the level of infection is relatively high. In the future, we should strengthen the popularization of knowledge on prevention and control of anisakiasis.
摘要
The data of a patient with carbamate pesticide poisoning were analyzed. Cardiac arrest, oliguria, acute renal injury and pulmonary infection occurred during treatment. After cardiopulmonary resuscitation, tracheal intubation, CRRT, anti-infection and other symptomatic support treatment, the patient recovered and discharged. The myocardial damage caused by carbamate pesticide poisoning is easy to be ignored, and it often causes cardiac manifestations such as arrhythmia and cardiac insufficiency, and the related markers of cardiac injury, electrocardiogram and echocardiogram are also changed. Therefore, the awareness of cardiac damage caused by carbamate pesticide poisoning should be improved.

Objective:To investigate the expressions of matrix metalloproteinase 7(MMP7)and secretory leukocyte protease inhibitor(SLPI)in papillary thyroid carcinoma(PTC)and their signifi-cances.Methods:Based on the gene expression data of thyroid cancer in the tumor Genome Atlas(TCGA)database,a total of 567 samples were collected,including 509 cancer tissues and 58 normal tissues.The gene matrix data were extracted and sorted out.Two groups of differentially expressed genes were screened by using the R language edger package,and the potential key genes were screened by the mcode plug-in in Cytoscape.Select a key gene and mine closely related genes through the UALCAN database.Immunohistochemical SABC method was used to detect the ex-pressions of MMP7 and SLPI proteins in PTC tissues and their paracancerous tissues collected from 69 patients in Binzhou People's Hospital Affiliated to Shandong First Medical University from January 2020 to June 2021,and the association of expression levels of MMP7 and SLPI with the clinico-pathological factors of PTC patients was also analyzed.Results:Based on the data of TCGA database,1471 genes were obtained,of which 1000 were up-regulated and 471 were down-regu-lated.Through the mcode plug-in in Cytoscape,20 key genes were screened(MMP7,CCL18,CYR61,SPECC1,CRABP2,PLXNA3,KRT17,TMEM59L,RETN,SRF,ITGB4,PPL,PLEKHN1,RMI2,LCN6,SPX,NRIP1,ARHGEF28,SLC39A14,SNCA).Through the UALCAN database,the correlation between MMP7 and SLPI was retrieved(Pearson correlation coefficient was 0.5,P＜0.05).The results of immunohistochemistry showed that the positive expression rates of MMP7 and SLPI proteins in PTC tissues were significantly higher than those in paracancerous tissues[82.6％(57/69)vs 29.0％(20/69),71.0％(49/69)vs 15.9％(11/69)],and the differences were statistically significant(x2 val-ues were 40.222 and 42.579,both P＜0.01).The expressions of MMP7 and SLPI in PTC tissues were correlated with TNM stage,differentiation,extramembranous invasion and lymph node metastasis(all P＜0.05).There was a positive correlation between MMP7 and SLPI proteins expressions in PTC(r=0.381,P=0.001).Conclusions:The interaction between MMP7 and SLPI proteins can be in-volved in the development and progression of PTC.
摘要
Posterior process fractures of the talus are rare so that they are likely to be overlooked. In recent years, a deeper understanding of the diagnosis, treatment and prognosis of these fractures has led to increasing treatment methods for them, but there are still no standard treatment guidelines. This article reviews the anatomy, classification, and treatment methods (including conservative management, open reduction and internal fixation, arthroscopic techniques, percutaneous closed reduction and internal fixation and robot-assisted reduction and fixation) of posterior process fractures of the talus, hoping to provide references for those surgeons who may select optimal treatment options for various kinds of the fractures.

Objective: To analyze the classification, diagnosis and treatment status of patients with pulmonary hypertension (PH) in Yunnan province. Methods: This was a retrospective study. Hospitalized patients with PH at Yan'an Affiliated Hospital of Kunming Medical University from January 2012 to December 2019 were enrolled. The clinical data of enrolled patients, including demographic data, comorbidities, targeted drug therapy, echocardiography and right heart catheterization results, were obtained through the electronic medical record system. The composition ratio of PH, diagnosis and treatment were analyzed. Results: A total of 13 590 patients with PH were enrolled, accounting for 3.09% (13 590/440 056) of the total number of hospitalizations during the same period. The composition of PH was predominantly pulmonary arterial hypertension (PAH) (55.50% (7 542/13 590)), followed by pulmonary hypertension (PH) caused by left heart disease (24.16% (3 284/13 590)). Among them, PAH could be subdivided into four types: idiopathic pulmonary arterial hypertension (IPAH), PAH associated with connective tissue disease, PAH associated with portal hypertension, and PAH associated with congenital heart disease (CHD-PAH), with CHD-PAH as the predominating type (98.09% (7 398/7 542). Patients with PAH were predominantly adolescents. In hospitalized patients with PH, from 2012 to 2019, the proportion of children and adolescents showed a decreasing trend from year to year, and the proportion of middle-aged and older adults showed a significant increasing trend, and the proportion of female patients showed a gradual decreasing trend, and the proportion of patients with comorbid hypertension, diabetes mellitus, coronary artery disease, arrhythmia, and pneumonia showed an increasing trend. A total of 1 034 patients (7.61% (1 034/13 590)) underwent right heart catheterization. The concordance rate between echocardiographic and right heart catheterization findings was (86.98% (875/1 006)). A total of 2 574 (18.94%) of PH patients were treated with PAH targeted drugs, of which 58.16% (1 497/2 574) were treated with monotherapy. Among the PH patients treated with PAH targeted drugs, the majority of patients were PAH patients (86.44% (2 225/2 574)), and 83.53% (2 150/2 574) patients treated with PAH targeted drugs were CHD-PAH. Conclusions: Hospitalized PH patients in our center between 2012 and 2019 are predominantly CHD-PAH, and the proportion of patients receiving right heart catheterization and targeted drug therapy is relatively low. The percentage of middle-aged and elderly PH patients shows an increasing trend from year to year, as well as the percentage of those with concomitant comorbidities.

ObjectiveTo observe the effect of warming needle moxibustion based on rehabilitation on rotator cuff injury. MethodsFrom January, 2019 to January, 2020, 70 patients with rotator cuff injury from Rehabilitation Hospital, Fujian University of Traditional Chinese Medicine were randomly divided into control group (n = 35) and experimental group (n = 35). Both groups received Mulligan mobilization and rotator cuff muscle group muscle energy technique (MET) training, while the experimental group received warming needle moxibustion at Jianyu (LI15), Jügu (LI16), Jianqian and Jianzhen (SI9) in addition, for two weeks. They were assessed with Shoulder Pain and Disability Index (SPADI), Visual Analogue Scale for pain (VAS), range of motion of shoulder (ROM), and shoulder isokinetic muscle strength before and after treatment, and the complications and recurrence were observed. ResultsThere were five cases in the control group and four cases in the experimental group dropped. The SPADI score, VAS score decreased (|t| > 5.039, P < 0.001), and the ROM and R value of isokinetic muscle strength testing increased (|t| > 2.751, P < 0.01) in both groups after treatment, while the SPADI score, VAS score were less (|t| > 3.616, P < 0.001); the ROM, and R values of isokinetic muscle strength testing of flexion, extension, adduction and abduction were more (|t| > 2.214, P < 0.05) in the experimental group than in the control group. ConclusionWarming needle moxibustion can further relieve shoulder pain in patients with rotator cuff injury, and improve shoulder ROM, muscle strength and functioning.

OBJECTIVE@#To investigate the effects of decitabine (DEC) combined with all-trans retinoic acid (ATRA) on the number of immune cells, efficacy and adverse reactions in the treatment of myeloid neoplasms patients.@*METHODS@#Eighty-four patients with myeloid tumors, including AML, MDS-EB-1 or MDS-EB-2 treated by the regimen containing decitabine in our hospital from January 2009 to October 2019 were enrolled and retrospectively analyzed, among the patients, 21 patients treated with DEC alone, 24 patients treated with DEC combined with ATRA (DEC/ATRA) and 39 patients treated with DEC combined with G-CSF priming regimen (DEC/priming). The changes of peripheral blood immune cell levels before and after treatment of the patients between the three groups were compared, and the differences in clinical efficacy and adverse reactions of the patients between the three groups were also compared.@*RESULTS@#There was no statistical differences in the number of immune cells among the patients in the three groups before treatment (P>0.05). NK cell levels decreased significantly in the patients in DEC and DEC/ATRA group after treatment (P<0.05); After treatment, the levels of CD8+ and CD3+T cells in the patients treated by DEC /priming regimen significantly increased (P<0.05), while the levels of CD3-HLA-DR+ B cells significantly decreased (P<0.05). The overall response rate (ORR) of the patients in DEC/ATRA group (75%) and DEC/priming group (74.36%) was significantly higher than 42.86% in DEC monotherapy group, and the differences showed statistically significant (P<0.05), while the ORR between the patients in DEC/ATRA and DEC/priming group showed no statistic differences (P>0.05). There were no statistical differences in overall survival (OS) and incidence of bleeding between the patients in the three groups (P>0.05). The incidences of grade 3 to 4 bone marrow suppression and the infection rate of the patients in DEC monotherapy and DEC/ATRA group were significantly lower than that in DEC/priming regimen group after treatment (all P<0.05), however, there was no statistical difference between DEC monotherapy and the DEC/ATRA group.@*CONCLUSION@#The efficacy of DEC/ATRA on myeloid neoplasms is comparable to that of DEC/priming regimen, and the anti-myeloid tumor effect of DEC/ATRA regimen may be related to the regulation of NK cells and T cells.

Objective:To explore the clinical features, diagnosis, treatment and prognosis of rectal neuroendocrine tumor with lymphatic metastasis.Method:There were 153 case who were diagnosed with RNET, among them, there were 10 patients(6.5%) with lymphatic metastasis in Affiliated Union Hospital, Tongji Medical College, Huazhong University of Science & Technology from January 2012 to December 2020, including 4 males and 6 females, aged from 32 to 71 years old, and the median age was 56.5 years.Results:Of the 10 patients, 3 had tumors < 1 cm in diameter, 4 had 1 to 2 cm, and 3 had > 2 cm. Preoperative CT examination was performed in 10 patients, of which 9 suggested lymphatic metastasis; preoperative MRI examination was performed in 7 patients, of which 6 suggested lymphatic metastasis. All patients were received radical resection, in which Miles operation was performed in 2 cases, Dixon operation in 6 cases, and additional Dixon operation after endoscopic submucosal dissection in 2 cases.All patients were followed up for 51 months (ranged from 14 to 118 months). Nine patients had no recurrence or metastasis, and one patient had abdominal metastasis 40 months after surgery and died after 31 months of comprehensive treatment.Conclusions:Lymphatic metastasis is rare in rectal neuroendocrine tumor. Imaging examination has important reference value for judging the status of lymphatic metastasis. For rectal neuroendocrine tumor with lymphatic metastasis, radical resection is effective.
