ABSTRACT

Objective:To summarize the clinical experiences of managing patients with novel coronavirus(2019-nCoV) infection after kidney transplantation.Methods:Clinical data were retrospectively analyzed for two patients with 2019-nCoV infection after renal transplantation in January 2020. Case 1 was a 48-year-old male with CMV pneumonia secondary to 2019-nCoV infection at 4 months post-transplantation. CT imaging showed multiple patchy ground-glass opacities of both lungs. Case 2 was a 59-year-old male who screened positive for 2019-nCoV nucleic acid due to fever at 9 days post-transplantation and he showed no clinical manifestations of pneumonia. After a definite diagnosis, case 1 was transferred to a designated hospital for isolation. Treatment regimens: cefoperazone sulbactam sodium plus linezolid for anti-infection, gamma globulin for enhancing immunity, methylprednisolone for controlling inflammatory responses and antiviral regimens of arbidol tablets plus lopina-velitonavir tablets. Case 2 was isolated in a single room. The treatment plan included cefoperazone sulbactam sodium for anti-infection, gamma globulin for enhancing immunity, arbidol for antiviral therapy and other symptomatic measures.Results:During a follow-up period of 3 weeks, case 1 recovered with renal dysfunction, nucleic acid test of nasopharyngeal swab turned negative and pulmonary imaging improved. Case 2 showed no obvious clinical symptoms and nucleic acid test of nasopharyngeal swab turned negative thrice.Conclusions:Renal transplant recipients should take precautions to avoid exposure to high-risk environments. A definite diagnosis should be made on the basis of clinical manifestations and results of nucleic acid test and pulmonary imaging. Currently there is no effective antiviral agent and symptomatic treatment is a major option.

ABSTRACT

BACKGROUND@#Liver fibrosis (LF) continues to develop and eventually progresses to cirrhosis. However, LF and early-stage cirrhosis (ESC) can be reversed in some cases, while advanced cirrhosis is almost impossible to cure. Advances in quantitative imaging techniques have made it possible to replace the gold standard biopsy method with non-invasive imaging, such as radiomics. Therefore, the purpose of this study is to develop a radiomics model to identify LF and ESC.@*METHODS@#Patients with LF (n = 108) and ESC (n = 116) were enrolled in this study. As a control, patients with healthy livers were involved in the study (n = 145). Diffusion-weighted imaging (DWI) data sets with three b-values (0, 400, and 800 s/mm) of enrolled cases were collected in this study. Then, radiomics features were extracted from manually delineated volumes of interest. Two modeling strategies were performed after univariate analysis and feature selection. Finally, an optimal model was determined by the receiver operating characteristic area under the curve (AUC).@*RESULTS@#The optimal models were built in plan 1. For model 1 in plan 1, the AUCs of the training and validation cohorts were 0.973 (95% confidence interval [CI] 0.946-1.000) and 0.948 (95% CI 0.903-0.993), respectively. For model 2 in plan 1, the AUCs of the training and validation cohorts were 0.944, 95% CI 0.905 to 0.983, and 0.968, 95% CI 0.940 to 0.996, respectively.@*CONCLUSIONS@#Radiomics analysis of DWI images allows for accurate identification of LF and ESC, and the non-invasive biomarkers extracted from the functional DWI images can serve as a better alternative to biopsy.

ABSTRACT

In December 2019, a number of cases of pneumonia with unknown causes were successively reported in multiple hospitals in Wuhan City, Hubei Province, China. The pathogen is a novel coronavirus, which can lead to novel coronavirus pneumonia (COVID-19) and even threaten the patients' lives. In the following, the COVID-19 epidemic is spreading rapidly in many provinces and cities. It is particularly important to summarize and analyze the clinical characteristics of COVID-19 in solid organ transplantation (SOT) recipients and to optimize the prevention, early diagnosis and treatment strategies. Therefore, we organized Chinese experts in the field of organ transplantation to draft this article according to the characteristics of lung infection of SOT recipients and the characteristics of current COVID-19 by referring to relevant guidelines and specifications at home and abroad, aiming to provide reference for transplant physicians in China. This management strategy will be revised at any time with the deepening understanding of the COVID-19 infection.

ABSTRACT

Abstract Purpose: To investigate the long non-coding RNAs (lncRNAs) profile on renal ischemia reperfusion in a mouse model. Methods: Microarray analysis was used to study the expression of misregulated lncRNA in a mouse model of renal ischemia reperfusion(I/R) with long ischemia time. Quantitative real-time PCR (qPCR) was used to verify the expression of selected lncRNAs and mRNAs.The potential functions of the lncRNA was analyzed by bioinformatics tools and databases. Results: Kidney function was impaired in I/R group compared to the normal group. Analysis showed that a total of 2267 lncRNAs and 2341 messenger RNAs (mRNAs) were significantly expressed in I/R group (≥2.0-fold, p < 0.05).The qPCR result showed that lncRNAs and mRNAs expression were consistent with the microarray analysis. The co-expression network profile analysis based on five validated lncRNAs and 203 interacted mRNAs showed it existed a total of 208 nodes and 333 connections. The GO and KEEG pathway analysis results showed that multiple lncRNAs are involved the mechanism of I/R. Conclusion: Multiple lncRNAs are involved in the mechanism of I/R.These analysis results will help us to further understand the mechanism of I/R and promote the new methods targeted at lncRNA to improve I/R injury.

ABSTRACT

BACKGROUND: The anterior cruciate ligament (ACL) is an extremely important static structure that stabilizes the structure of the knee joint. Many scholars have found that an insufficient understanding of normal anatomical structure and biological characteristics of the ACL results in poor outcomes in the ACL reconstruction. OBJECTIVE: To compare the clinical effects of single-bundle and double-bundle single-tunnel techniques in ACL reconstruction with allogeneic tendon. METHODS: (1) Anatomy research: Six fresh knee joints were used for the experiments, and X-ray, CT and MRI were taken for each sample to confirm no osteoclasia, tumor and collapse of ACL. Then the ACL was stripped from the tibial bone and used to run hematoxylin-eosin staining and observe the fiber distribution of each piece of the ACL. (2) Clinical research: A total of 40 cases of ACL arthroscopic reconstruction were involved in this study, including 19 single-bundle ones and 21 double-bundle ones. The International Knee Documentation Committee 2000 subjective knee form (IKDC2000), Tegner and Lysholm evaluations were performed in all the patients. Paired t-test was used to analyze the IKDC, Tegner and Lysholm scores before operation and at follow-up time. RESULTS AND CONCLUSION: Anatomy research: From the view of anatomy, there was no evidence to support the double beams of the ACL at the tibial end by hematoxylin-eosin staining. Clinical research: Forty patients (40 knee joints) were successfully followed for over 12 months, and their joint range of motion was normal. The IKDC, Tegner and Lysholm scores were all improved in both two groups after the surgery, while the Larson scores were significantly higher in the double-bundle group than the single-bundle group. To conclude, the single-tunnel double-bundle ACL reconstruction is better to restore the knee stability than the single-bundle ACL reconstruction. This is an easy operation that has the merits of operating conveniently, restoring the normal anatomy of the tibial end, and exhibiting excellent short-term therapeutic effects. However, its long-term effects are uncertain.

ABSTRACT

Estrogen receptor (ER) and progesterone receptor (PR) are two important members of steroid receptors family, an evolutionarily conserved family of transcription factors. Upon binding to their ligands, ER and PR enter cell nucleus to interact with specific DNA element in the context of chromatin to initiate the transcription of diverse target genes, which largely depends on the timely recruitment of a wide range of cofactors. Moreover, the interactions between steroid hormones and their respective receptors also trigger post-translational modifications on these receptors to fine-tune their transcriptional activities. Besides the well-known phosphorylation modifications on tyrosine and serine/threonine residues, recent studies have identified several other covalent modifications, such as ubiquitylation and sumoylation. These post-translational modifications of steroid receptors affect its stability, subcellular localization, and/or cofactor recruitment; eventually influence the duration and extent of transcriptional activation. This review is to focus on the recent research progress on the transcriptional activation of nuclear ER and PR as well as their physiological functions in early pregnancy, which may help us to better understand related female reproductive diseases.

ABSTRACT

Objective To investigate the effect and mechanism of pretreatment with allopurinol on renal ischemia-reperfusion injury (IRI)in rats.Methods Twenty four rats were randomly assigned into the sham operation (S), ischemia-reperfusion (IR)and allopurinol pretreatment (APC)groups (n =8 for each group).At preoperative 2 weeks, allopurinol at a dose of 50 mg/(kg·d)was administered via intraperitoneal injection in the APC group,and an equivalent quantity of physiological saline was given via intraperitoneal injection in the S and IR groups.After pretreatment,the right kidneys of rats in the S group were resected.In the IR and APC groups,the right kidneys were resected and the left kidneys were treated with 30 min ischemia-reperfusion.Blood sample was collected at 24 h after reperfusion and the kidney specimen was obtained at postoperative 2 weeks.The levels of blood urea nitrogen (BUN)and serum creatinine (Scr)were detected by automatic biochemistry analyzer.The activity of plasma malondialdehyde (MDA)and superoxide dismutase (SOD)was respectively assessed by detection kits.The expression levels of Bax,Bcl-2 and Caspase-3 of rat kidney were measured by western blot.Pathological changes in the rat kidney were observed under light microscope.Cell apoptosis of rat kidney was evaluated by TdT mediated-dUTP nick end labeling (TUNEL).Results Compared with the S group,the levels of BUN, Scr and plasma MDA in the IR and APC groups were significantly increased,whereas the activity of plasma SOD was significantly reduced (all in P <0.05).Compared with the IR group,the levels of BUN,Scr and plasma MDA in the APC group were significantly reduced,whereas the activity of plasma SOD was considerably elevated (all in P <0.05).Compared with the S group,the expression levels of Bax and Caspase-3 proteins were significantly up-regulated in the IR and APC groups,and the levels in the APC group were considerably lower than those in the IR group (all in P <0.05).Compared with the S group,the expression of Bcl-2 in rat kidney in the IR and APC groups was significantly down-regulated,and the value in the APC group was dramatically higher than that in the IR group (all in P <0.05).Under light microscope,the morphology of rat kidney was intact and normal in the S group.In the IR group,evident renal tubular ectasia,massive necrosis of renal tubular epithelial cells,evident stromal edema and a large quantity of lymph cellular infiltration were observed.In the APC group,mild renal tubular ectasia was observed,whereas no apparent kidney stromal edema was noted.A slight amount of lymph cellular infiltration was noted in the stroma.TUNEL staining revealed that the apoptosis rate of kidney cells in the S,IR and APC groups was (4.1 ±1 .7)%,(32.8 ±8.9)% and (1 2.6 ±3.4)% (all in P <0.05).Conclusions Allopurinol pretreatment could suppress cell apoptosis through anti-oxidation effect,thereby alleviating IRI of rat kidney and improving renal function.

ABSTRACT

In this study, we focused on the study of pharmacodynamic effects for 6 major bioactive lignans of Schisandra chinensis, namely deoxyschizandrin, schisandrin B, schisandrin C, schisandrin, schizandrol B and schisantherin A. A compound-gene-pathway network, which contained 124 related genes and 88 pathways, was constructed by collecting drug genes through mining relevant literatures and network pharmacology analysis. Based on the network analysis, 32 pathways and 80 related genes were associated with inflammation, which implied that anti-inflammatory might be the major pharmacodynamic effects of these compounds. All lignans except schizandrol B reduced LPS-induced NO production in RAW264.7 cells, which validated the anti-inflammatory hypothesis generated from network analysis. Furthermore, we investigated the effects of deoxyschizandrin, schisandrin C, schisandrin and schisantherin A on the secretion of inflammatory cytokines TNF-α, IL-1β, IL-6, PGE2 and protein expressions of iNOS, COX-2. As a result, deoxyschizandrin showed the strongest anti-inflammatory activity with inhibitory effect on all 4 inflammatory cytokines secretions and protein expressions of iNOS, COX-2. This study provided evidences for systematic exploration on the pharmacolgical actions and mechanisms of schisandra.

ABSTRACT

To explore the clinical effect of ganglioside sodium in the treatment of acute cerebral infarction and its influ-ence on hs-CRP and TNF-α in serum. Methods:A total of 216 patients with acute cerebral infarction were randomly divided into the observation group and the control group. The control group (108 cases) was given regular treatment, and the observation group (108 cases) was given 100 mg ganglioside in 250 ml 0. 9% sodium chloride, ivd, qd additionally, and the treatment course was 14d. The clinical effect of the two groups was compared, and the change of hs-CRP and TNF-αin serum was also researched in both groups. Re-sults:The total effective rate of the observation group was 90. 7%, which was obviously higher than that of the control group (71. 3%, P<0. 05). After the treatment, the NDS score of the observation group was lower than that before the treatment, while the ADL score was higher than that before the treatment (P<0. 05). After the treatment, the level of hs-CRP and TNF-α in serum was higher than that before the treatment in the two groups (P<0. 05), and that in the observation group was higher than that in the control group (P<0. 05). During the treatment, no adverse reaction was shown in the two groups. Conclusion:The clinical effect of ganglioside sodi-um in the treatment of acute cerebral infarction is promising, which can reduce the level of hs-CRP and TNF-αin serum of the patients and improve the scores of NDS and ADL with good safety, and is worthy of further clinical application.

ABSTRACT

Objective To compare clinical efficacy and safety between standard double-and single-dose of basiliximab in renal transplantation.Methods A total of 121 patients undergoing allogeneic cadaveric renal transplantation in Department of Urology of Renmin Hopsital of Wuhan University from January 2008 to May 2011 were recruited as study subjects.Among them,53 patients were assigned into the double-dose of basiliximab group and they were intravenously administered with 20 mg of basiliximab before and 4 d after surgery according to product description.Sixty-eight cases were allocated in the single-dose of basiliximab group and they were given with 20 mg of basiliximab before renal transplantation.The changes of immune function in two groups during perioperative period were monitored.The incidence of adverse reactions including delayed graft function (DGF),acute rejection,pulmonary infection and the survival of patients and renal grafts were statistically compared between two groups.Results There was no significant difference in preoperative humoral immune and cellular immune function between two groups.Compared with preoperative period,cellular and humoral immune function in both groups were inhibited by varying degree at 5 d after surgery (both in P <0.05).Compared with patients in the single-dose group,cellular and humoral immune functions were evidently suppressed in the double-dose group (both in P <0.05).Compared with the parameters assessed at 5 d after surgery,cellular and humoral immune functions were restored to varying degree at 15 d after surgery,whereas still significantly lower than preoperative levels (CD3,CD4,IgM and IgA).Partial parameters (CD8 and IgG)were persistently inhibited and continued to decline compared with the levels at 5 d after surgery.The incidence of DGF was 8% in the double-dose group,and 7% in the single-dose group.During 1-year follow-up,the rejection rates in the double-and single-dose groups were 13% and 12%,and the incidence of pulmonary infection was 9% and 10%.No statistical significance was noted between two groups in terms of these parameters (all in P >0.05).The 1-year survival of patients in the double-and single-dose groups was 94% and 98%,93% and 96% for the survival of renal grafts.No statistical significance was found between two groups (both in P >0.05).Conclusions Both double-and single-dose of basiliximab are efficacious in renal transplantation and do not increase the incidence of adverse reaction.The 1-year survival rates of patients and renal grafts between two groups are almost equivalent.Detection of immune function during perioperative period effectively guides individualized immune induction therapy.

<p><b>OBJECTIVE</b>To analyze the epidemiological characteristics of the HIV/AIDS patients newly received highly active antiretroviral therapy (HAART) during 2005-2013 in Jiangsu province.</p><p><b>METHODS</b>According to the baseline data of HIV/AIDS patients newly received HAART during 2005-2013, an Excel database was established and statistical analysis was performed using SPSS 16.0 software.</p><p><b>RESULTS</b>There were 5 788 HIV/AIDS patients newly received HAART during 2005-2013 and the number increased annually. 79.7% of these patients were from the local province, with the ratio of male to female as 4.69 : 1, mean age as 39.9 years old, 55.8% of them married, 52.0% of them were treated at CDC. 91.9% of them were infected through sexual contacts. Mean baseline CD4(+)T cell count of cases was 187 cells/µl. Median of the interval between the time of HIV confirmation and HAART initiation was 4.0 months. Proportion of the HIV/AIDS patients that were being male, elderly, unmarried, not local resident, treated in hospitals and with higher baseline CD4(+)T count etc. showed a trend of increase.</p><p><b>CONCLUSION</b>HIV/AIDS patients had the opportunity to start the HAART at early stage of the disease. However, many of them started the treafment late as the results of being diagnosed late. Programs related to both earlier detection and diagnosis on HIV cases should be strengthened.</p>
