Objective:To observe the clinical outcomes of living related kidney transplantation (LRKT) recipients with hyperuricemia.Methods:A retrospective analysis was conducted on the medical records of 212 cases of LRKTs performed between Jan. 2015 and Dec. 2021. All cases involved children who received a kidney transplant donated by their parents. Based on the average blood uric acid levels (>420 μmol/L) between 1 to 12 months postoperatively, the patients were divided into two groups: the hyperuricemia group (HUA, n=43) and the non-hyperuricemia group (non-HUA, n=169) . Demographic information, the incidence of adverse events within one year after the operation, serum creatinine (Scr) levels, and the survival rate of the transplanted kidney at 1, 3, and 5 years after the operation were compared between the groups. Results:The non-HUA group had a significantly shorter preoperative dialysis duration compared to the HUA group (median 350 days vs 484 days) . The incidence of delayed graft function and acute rejection within 1 year postoperatively was significantly higher in the HUA group compared to the non-HUA group (14.0% vs 4.7% and 11.6% vs 2.4%) . At 1, 3, and 5 years after surgery, the serum creatinine levels in the HUA group were significantly higher than those in the Non HUA group, which were (131.1±31.2) vs (116.3±32.1) mmol, (133.6±34.7) vs (119.9±31.9) mmol/L, and (137.3±32.4) vs (115.4±30.3) mmol/L. The survival rate of kidney transplantation was slightly lower in the HUA group compared to the non-HUA group, but the difference was not statistically significant.Conclusions:Hyperuricemia in kidney transplant recipients who received a donor kidney from their parents is associated with increased incidences of delayed graft function and acute rejection, as well as compromised graft kidney function.
ABSTRACT
Clinical decision-making has been perceived as a primary cognitive activity for clinicians in daily practice,which based on the process of choosing between alternatives or options for patients.A single clinical decision might affect one patient's health outcomes,while the sum of clinical decisions made by all clinicians would play a decisive role in the allocation and utilization of health resources.Several dimensions should be taken into consideration when making clinical decisions,such as scientificity,clinical experience,economical status,medical humanities and government administration.In addition,clinical decision-making behavior should be administrated and guided by government,from the following seven aspects,so as to avoid "scientism" or " commercial alienation" phenomenon:national guidelines and standards development,academic standardization,expertise offering,medical training with human factors as well as legal punishment,medical knowledge accessibility,reimbursement restriction,and application of artificial intelligence.
ABSTRACT
With dramatic decline of genome sequencing cost,high-throughput sequencing technologies have been applied in clinical laboratory field,and play an increasingly important role in clinical diagnosis and treatment in complex diseases.Based on omics techniques,clinical laboratory data recording patient's diagnosis information has become the important independent medical research resources of the major health industry.Because these data include the patient's identity information,there are a series of ethical issues to be solved,such as protection of patients' informed consent right,patient privacy protection,information security protection,when carrying out the medical health big data research.Based on these problems,it proposed clinical laboratory data should be standard extraction,establishment of clinical laboratory data base for teaching,training,in order to improve the utilization of medical resources.Moreover,it is best to implement the written informed consent during the process of sample collection,informing the patient the data collected in diagnosis and treatment process may be used in related research in future.

ABSTRACT
<p><b>BACKGROUND</b>Chronic exposure to n-hexane can lead to peripheral neuropathy that no effective treatment regimen could be applied presently. This study investigated whether myelin protein zero (P0) protein and its antibody could be used to distinguish n-hexane intoxication and protect workers from peripheral neuropathy.</p><p><b>METHODS</b>We compared P0 protein and its antibody among three levels of n-hexane-exposed groups, which included 18 patients with n-hexane-induced peripheral neuropathy as case group, 120 n-hexane-exposed workers as n-hexaneexposed control group, and 147 non-hexane-exposed participants used as control group. ELISA method was applied to detect P0 protein and its antibody.</p><p><b>RESULTS</b>P0 protein in serum was significantly higher in the case group and n-hexane-exposed control group in comparison with the control group (P < 0.01). Compared with the n-hexane-exposed control group, the case group also had significant increase of P0 protein (P < 0.01). After 6 months therapy, P0 protein was observed to decrease significantly in the case group (P < 0.01). The P0 antibody in serum was significantly higher in the n-hexane-exposed control group than in the control group (P < 0.01), but not significantly different between cases and controls.</p><p><b>CONCLUSIONS</b>P0 antibodies in serum may be a short-term effect biomarker for n-hexane exposure. P0 protein in serum may be an early effective biomarker for peripheral nerve neuropathy and its biological limit value needs investigation in the future study.</p>

<p><b>OBJECTIVE</b>To study the role of poly (ADP-ribose) polymerase-l (PARP-1) in formaldehyde-induced DNA damage response in human bronchial epithelial (HBE) cells and to investigate the mechanism of formaldehyde carcinogenicity.</p><p><b>METHODS</b>The protein levels were measured by Western blot. The interaction between different proteins was determined by co-immunoprecipitation assay. The chemical inhibitor was used to confirm the relationship between PARP-1 and DNA damage repair.</p><p><b>RESULTS</b>After being exposed to different concentrations of formaldehyde for 4 h, HBE cells showed no significant changes in cell viability. Cell viability was significantly reduced after 24-h exposure to 80 and 160 µmol/L formaldehyde (P < 0.05). The 10 µmol/L formaldehyde resulted in significant increases in the protein levels of PARP-1 and XRCC-1. However, 80 µmol/L formaldehyde led to a significant decrease in the protein level of PARP-1 of 124 KD molecular weight but a significant increase in the protein level of PARP-1 of 89 KD molecular weight; there was no significant change in the protein level of XRCC-1. The co-immunoprecipitation assay showed that 10 µmol/L formaldehyde induced increased binding between PARP-1 and XRCC-1, but 80 µmol/L formaldehyde led to no significant change in binding between PARP-1 and XRCC-1. Here, we confirmed the role of 10 µmol/L formaldehyde in strand breaks by comet assay which showed an increase in the tail DNA content of HBE cells after 4-h formaldehyde exposure. No significant difference was observed in tail DNA content between treated HBE cells and control cells at 2 h after formaldehyde was removed. Moreover, compared with control, inhibition of PARP-1 induced a significant increase in tail DNA content, and a significant difference was observed in tail DNA content between inhibited HBE cells and control cells at 2 h after formaldehyde was removed. Inhibition of PARP-1 significantly reduced DNA repair capacity.</p><p><b>CONCLUSION</b>PARP-1 mediated the repair of DNA damage induced by low-concentration formaldehyde through recruiting XRCC-1 protein, and may be involved in the regulation of cell apoptosis induced by high-concentration formaldehyde.</p>

<p><b>OBJECTIVE</b>To investigate the roles of ceruloplasmin (Cp) in PI3K/PTEN cell signaling pathway change in human embryonic lung fibroblasts (HELFs) induced by silica.</p><p><b>METHODS</b>HELFs transfected with pGenesil1.1 plasmid and pGenesil1.1 with PTEN shRNA (PT) plasmid were successfully established. 100 µg/ml silica and different concentrations of Cp (10, 20, 30 µg/ml) were used in this experiment and Cp were treated cells after exposed to silica for 1h. Three different cell lines (including HELFs, PT and cells were transfected with p85 dominant negative mutant plasmid (DN-p85)) were divided into control groups, silica groups and silica+different concentrations of Cp groups. MTT assay was used to detect the effects of Cp on silica-induced cell proliferation after inhibiting PTEN and p85. When suppressing the expression of PTEN and p85, western blot assay was performed to detect the levels of p85, p110, AKT308, AKT473 and ERK, JNK and their phosphorylated levels.</p><p><b>RESULTS</b>After inhibition of PTEN, the high levels of p85 induced by 100 µg/ml silica with 30 µg/ml Cp were markedly decreased (P<0.05). When suppressing p85, the increased cell proliferation was not observed. And the high levels of AKT308, AKT473, ERK and phosphorylated JNK and ERK stimulated by 100 µg/ml silica with 30 µg/ml Cp were decrease (P < 0.05).</p><p><b>CONCLUSION</b>Cp could further strengthened silica-induced cell proliferation by PI3K/AKT/MAPK cell signaling pathway, of which the level of p85 was regulated by PTEN.</p>

Clinical practice guidelines have been widely applied worldwide.Compared with the developed countries,however,the development of guidelines still has many limitations in China,which is mainly due to the lack of a guideline for guiding this process.Such a guideline,defined as “a structured and coordinated programme designed with the specific aim of producing several clinical practice guidelines should be able to specify the development,dissemination,implementation,evaluation,and update of each clinical practice guideline.Furthermore,the lack of high-quality randomized controlled trials and cohort studies also restricts the development of high-level guidelines.After the development of such a guideline for developing guidelines,we can expect the faster development of Chinese clinical practice guidelines that are more carefully designed,more reliable,and more practical.
ABSTRACT
Many medical journals have already digitalized their publishing procedure,but not achieved digital publishing yet.Utilizing digital technology,digital publishing can achieve the functions that paper media cannot,such as information storage,fast search,real-time publishing,individualized information and interaction with readers.These functions entail digitalization of medical journals,and involve a range of macro- and micro-modifications,including laws,industry policies,personnel training,and culture development.There is a long way to go for Chinese medical journals to enter the stage of digital publishing.
ABSTRACT
Clinical practice guidelines are systematically developed clinical multi-discipline advisory statements which assist providers, recipients and other stakeholders to make informed decisions about appropriate health interventions. Chinese government and some clinical academic communities began to develop the domestic guidelines after 2000. Nevertheless, there were still some shortcomings presented in the domestic guidelines if assessed by the advanced appraisal instrument of the developed countries. There were four aspects as follow. The first, misunderstood the guidelines are the rule or text book. The second, ignored presentation of the procedure about development of guidelines. The third, there were a lack of high level evidences. The fourth, not declared editorial independence. However, it is necessary to develop the domestic guideline of China. With rising conflicts between the increasing needs for health care and shortage of our environment resource, development of the guidelines become one of the key steps in the process of clinical practice.
ABSTRACT
Objective To detect mutations of the RET proto-oncogene in a family with multiple endocrine neoplasia type 2A (MEN2A). Methods Nineteen family members were recruited in the study. The phenotype of the members with MEN2A were observed. PCR was performed to amplify exans 10 and 11 of the RET proto-oncogene. The PCR products were purified and a direct DNA sequence analysis was performed. Results The Cys (TGC)634Arg(CGC) missense mutation and Gly( GGT)691Ser(AGT) in exon 11 of the RET proto-oncogene were both detected in four members of the family. Only the pelymorphism Gly691Ser in exon 11 of the RET proto-oncogene was detected in one member. The results of the ultrasound examination were shown as follows: two members with bilateral thyroid, one side of parathyroid and adrenal solid lesions; one member with bilateral thyroid and one side of adrenal solid lesions; one member with bilateral thyroid and adrenal and one side of parathyroid solid lesions; and one member with multiple thyroid small nodules. Additionally, another three members with abnormal findings on ultrasound examinations had no gene mutation. Conclusion Analysis of RET gene identifies a TGC to CGC mutation at codan 634 and the polymorphism Gly691 Set in exon 11 in this family with MEN2A. Direct DNA sequencing analysis is useful in diagnosis of MEN2A at gene level.
