CD56bright NK cell expansion correlated with EBV reactivation control post allogeneic hematopoietic stem cell transplantation.

Natural killer (NK) cells are equipped with anti-Epstein-Barr virus (EBV) function, however, whether EBV infection will affect NK cells reconstitution after allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains unclear. To identify the characteristics of NK cells, we prospectively enrolled 11 patients who occurred EBV reactivation post allo-HSCT and 11 patients without EBV infection as control. We found that that EBV infection induced the expansion of CD56bright and NKG2A+KIR- NK subsets,and decreased the cytotoxicity function of NK cells. The frequency of NKG2A+KIR- NK cells were higher in patients who progressed into post-transplant lymphoproliferative disorder (PTLD) than EBV viremia patients, which also correlated with decreased proliferation and cytotoxic function. By screening the activation receptors of NK cells, we found the DNAM-1+CD56bright NK cells is significantly increased after EBV stimulation, further we demonstrated that DNAM-1 is essential for EBV induced NK cells activation as the cytokine release against EBV-transformed lymphoblastoid cell lines(EBV-LCLs) of CD56bright NK cells were significantly decreased after DNAM-1 blockade. NK cells infusion suppressed the progression of EBV-related tumor mice model. A prospective cohort indicated that old donor age was an independent risk factor for EBV infection. Rapid CD56bri expansion and high expression of DNAM-1 on CD56bri NK cells in response to EBV reactivation correlated with rapid EBV clearance post allo-HSCT in patients with younger donors. In summary, our data showed that high expression of DNAM-1 receptors on NK cell may participate protective CD56bri NK cells response to EBV infection after allo-HSCT.

Availability of anesthesia equipment in Chinese hospitals: is the safety of anesthesia patient care assured?

Availability of physiologic monitoring equipment to ensure the safe administration of anesthesia is an expected standard in many parts of the world. Many hospitals in China may not have an adequate quantity and variety of anesthesia delivery and patient monitoring equipment to assure safe administration of anesthesia patient care. We present some typical cases of hospitals of different sizes and located in regions with different economic levels; our data demonstrate that there is a lack of available anesthesia administration and patient monitoring equipment in small hospitals and hospitals in economically underdeveloped regions.

In vivo confocal microscopic observations of 49 patients with posterior polymorphous corneal dystrophy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the imaging features of 49 patients with posterior polymorphous corneal dystrophy(PPCD)by in vivo confocal microscopy(IVCM).METHODS: Retrospective case series study. A total of 49 patients(86 eyes), including 32 males and 17 females diagnosed with PPCD between January 2013 and January 2021 were collected. The mean age was 42.5±22.9 years. All patients were scanned by IVCM to analyze the density of corneal endothelial cells and described IVCM characteristics of different types of PPCD.RESULTS: The number of endothelial cells in the lesion area of all patients was lower than that in the peripheral area. Under IVCM, 44 eyes(51%)were categorized into type 1 PPCD(vesicular lesions), characterized by single or multiple, central round or irregular crater-like lesion on paracentral corneal endothelial layer; 16 eyes(19%)were categorized into type 2 PPCD(band lesions), which displayed curved and raised edge with scattered or banded-distributed gutta-like lesion between edges. Type 3 PPCD(diffuse lesion)were in 26 eyes(30%), which showed that endothelial cells were missing in many areas. The blurred images of endothelium in most areas featured with spikes lined in a streak, and the clear images in some areas featured with a band lesions. Two patients were followed up for 4-5a. The IVCM images showed different lesions, including the decrease of central corneal endothelial cell density and the iron deposit in the corneal epithelium, etc.CONCLUSION: IVCM is able to scan the characteristic microstructural alterations at the level of endothelium and Descemet membrane in patients with PPCD, and provide an effective image diagnosis for PPCD.

[Analysis of epidemiological characteristics of imported malaria cases in Chongqing Municipality in 2015].

OBJECTIVE: To analyze the laboratory diagnosis results and epidemiological characteristics of imported malaria cases in Chongqing Municipality in 2015. METHODS: According to the Standard Operating Procedures of Malaria Diagnosis Reference Laboratory Manual, all the blood samples collected from the imported malaria patients were detected by microscopy, RDT and nest PCR. Meanwhile, the epidemiological data of the malaria cases were collected from the Parasitic Diseases Information Management System and analyzed. RESULTS: Totally 31 cases of imported malaria were reported in Chonqing Municipality in 2015, among which, there were 2 vivax malaria cases (6.45%), 23 falciparum malaria cases (74.19%), 5 ovale malaria cases (16.13%), 1 malariae malaria case (3.22%). For the 5 ovale cases, three of them were confirmed as Plasmodium ovale wallikeri infection. Among all the cases, 30 cases (96.77%) were from African countries, 1(3.33%) was from Southeast Asia. Thirty patients were male, and 1 was female. All the patients were aged from 23-61 years. There was no obvious seasonality in the case distribution. Both the medians of duration from malaria attack to first visiting a doctor and from first visiting a doctor to diagnosis were 2 days. The medical care units that the patients first visited were mainly county-level units, while those that made the diagnosis were mainly provincial level institutes. CONCLUSIONS: All the malaria cases in Chongqing in 2015 are imported, no local cases have been found, which suggests that this municipality still maintain the malaria elimination state. However, the monitoring and management of imported malaria cases as well as the training on malaria control for related medical staff still need to be strengthened.

Mediating effect of general self-efficacy between stress coping personality and perceived professional benefits among nursing interns / 中国职业医学

OBJECTIVE: To explore the mediating effect of the general self-efficacy(GSE), stress coping personality(SCP) and perceived professional benefits(PPB) among nursing practice students. METHODS: A total of 836 nursing interns from six grade A hospitals in six cities were selected as the research subjects using convenience sampling method. The GSE, SCP and PPB were investigated by the General Self-Efficacy Scale, Scale of Stress Coping Personality for College Students and Questionnaire of Nurses Perceived Professional Benefit. RESULTS: The average scores of GSE, SCP, and PPB were(24.6±5.8),(183.1±28.7) and(139.5±18.0), respectively. The scores of GSE and SCP were positively correlated with that of PPB [correlation coefficients(r) were 0.31 and 0.38 respectively, both P<0.01], and a positive correlation was found between GSE and SCP(r=0.41, P<0.01). The hierarchical regression results showed that the sense of control, tenacity and tolerance of SCP of the interns had a predictive effect on their PPB(all P<0.05); but the effect of SCP on PPB was weakened after inclusion of GSE(P<0.01). The structural equation model analysis results showed that both SCP and GSE of interns had a direct positive predictive effect on PPB(all P<0.01), GSE played a partial mediating role between SCP and PPB, accounting for 20.3% of the total effect. CONCLUSION: The SCP of nursing interns can directly or indirectly affect their PPB, and GSE plays a partial mediating effect between SCP and PPB.

Retrospective analysis of researches on credibility evaluation index system of medical institutions / 中华医院管理杂志

Objective:To systematically evaluate the dimensions and indexes of the credibility index system of medical institutions, for the purpose of providing reference for the development of the credibility evaluation index system of medical institutions.Methods:Literatures and government documents on " the credibility of medical institution" and its index system were collected from PubMed, Web of Science, CNKI, WanFang Data and VIP database, by means of literature retrieval. These data so retrieved were then extracted, classified and summarized. The retrieval time ranged from the founding time of the database to February 2020.Results:Thirteen literatures related to the credibility evaluation index system of medical institutions were included. The credibility rating index system of medical institutions involved a total of 57 dimensions. There were a total of 467 indexes, among which 168 were related to medical quality, operation management, practice review, medical expenses and comprehensive evaluation, while only 15 were selected for frequency≥3 times in each dimension.Conclusions:According to the literatures, only the indexes of professional qualification, medical quality and medical expenses were highly adopted, while others lacked the consistency. The problems result from huge differences in the index setting structure, unreasonable classification of index categories, gaps between government indexes and scientific research indexes, and the lack of detailed index description. Therefore, it is necessary to strengthen theoretical research on the credibility evaluation of medical institutions, clarify the policy background of the credibility evaluation of medical institutions, and further explain the indexes in detail.

Advance in Neural Regulation Networks of Anticipatory Postural Adjustments (review) / 中国康复理论与实践

The generation and execution of anticipatory postural adjustments (APAs) depend on the complex distributed neural networks, involving cerebral cortex (including premotor cortex and primary motor area), thalamus, basal ganglia, cerebellum, and divided into stratified mode and parallel mode. The basal ganglia and premotor cortex contribute to code the motor planning of APAs. Supplementary motor area and pedunculopontine nucleus in the brainstem co-regulate the timing of APAs. Primary motor area projects cortical motor fibers to target area during the initiation of APAs. The pontomedullary reticular formation integrates and projects fibers to the spinal cord. The cerebellum is mainly related to the coordinated coupling of muscles during APAs.

Choroidal thickness in severe congenital ptosis with amblyopia / 中华实验眼科杂志

Objective:To measure the choroidal thickness (CT) in the macular area of patients with amblyopia in severe congenital ptosis and to compare the thickness with that of severe congenital ptosis without amblyopia.Methods:A cross-sectional study was performed.Total of 83 eyes of 60 severe congenital ptosis patients were enrolled from January to October in the year 2019 in the Shanxi Eye Hospital, including 29 patients 37 eyes with amblyopia and 36 patients 46 eyes without amblyopia.Thirty-seven eyes of 37 normal people were included in the control group.All subjects underwent mydriatic optometry and the spherical equivalent (SE) was calculated.IOL-Master was used to measure the axial length (AL), and EDI-OCT was used to measure the CT in the macular area.The CT was measured at 13 points: directly beneath the fovea (SFCT) and at 1 mm, 2 mm and 3 mm intervals to the nasal, temporal, superior and inferior to the fovea.The points of CT measurements were named according to their positions and distances relative to the fovea, and represented by SFCT, N1, N2, N3, T1, T2, T3, S1, S2, S3, I1, I2, I3 respectively.The SE, absolute astigmatism degree, AL and CT at each point were compared among the groups.The corrected AL covariance analysis was used to compare the CT at different measurement points among the groups.Spearman rank correlation analysis was used to evaluate the correlation between CT and AL or SE, and unitary linear regression analysis was used to evaluate the influence of age on AL in each group.This study was approved by the Ethics Committee of Shanxi Eye Hospital.All the subjects signed informed consent.Results:Compared with the non-amblyopia group and control group, the SE and absolute astigmatism value was larger, and the AL was shorter in the amblyopia group (all at P<0.05). The mean SFCT was (388.85±54.85), (301.48±56.68), and (287.08±61.88)μm in the amblyopia group, non-amblyopia group, and control group, respectively.Except for I3, the CT values of the rest parts in the amblyopia group were greater than those in the non-amblyopia group and the control group (all at P<0.05). Except for S3 and I3, the CT values of the rest parts in the amblyopia group were greater than those in the non-amblyopia group and the control group after adjusting the AL ( P<0.05). In all the three groups, the CT value was high in the subfovea and was thin in the nasal side.The SFCT was negatively correlated with AL (amblyopia group: rs=-0.340, P=0.045; non-amblyopia group: rs=-0.340, P=0.020; control group: rs=-0.463, P<0.001) and positively correlated with SE (amblyopia group: rs=0.350, P=0.039; non-amblyopia group: rs=0.412, P=0.004; control group: rs=0.450, P=0.005) in each group.Age was the influencing factor of AL in the non-amblyopia group and the control group ( β=0.243, 0.225; both at P<0.001). Conclusions:In comparison with severe congenital ptosis without amblyopia, the SE and absolute astigmatism degree are larger, the AL is shorter, and the CT values at most areas are higher in the severe congenital ptosis with amblyopia.CT value may be associated with the development of amblyopia in severe congenital ptosis.

OBJECTIVE@#To investigate the effect of other gene mutations outside the fusion gene on the first complete remission (CR) induced by one course of induction chemotherapy in patients with core binding factor-associated acute myeloid leukemia (CBF-AML).@*METHODS@#DNA was extracted from bone marrow or peripheral blood samples of newly diagnosed CBF-AML patients admitted to the Hematology Department of the Second Hospital of Shanxi Medical University from January 2015 to January 2019. Next-generation sequencing was used for detection of 34 kinds of hematologic malignancy-related gene mutations in patients with CBF-AML, the effect of related gene mutations on the first complete remission (CR) rate in one course of induction chemotherapy was analyzed by combineation with clinical characteristics.@*RESULTS@#34 kinds of genes in bone marrow or peripheral blood of 43 patients were detected by high throughput sequencing and the gene mutations were detected in 16 out of 34 genes. The mutation rate of KIT gene was the highest (48.8%), followed by NRAS (16.3%), ASXL1 (16.3%), TET2 (11.6%), CSF3R (9.3%), FLT3 (9.3%), KRAS (7.0%). The detection rates of mutations in different functional genes were as follows: genes related with signal transduction pathway (KIT, FLT3, CSF3R, KRAS, NRAS, JAK2, CALR, SH2B3, CBL) had the highest mutation frequency (72.1% (31/43); epigenetic modification gene mutation frequency was 30.2% (13/43), including ASXL1, TET2, BCOR); transcriptional regulation gene mutation frequency was 7.0% (3/43), including ETV6, RUNX1, GATA2). Splicing factor related gene mutation frequency was 2.3% (1/43), including ZRSR2). The CR rate was 74.4% after one course of induction chemotherapy. At first diagnosis, patients with low expression of WT1 (the median value of WT1 was 788.9) were more likely to get CR (P=0.032) and the RFS of patients who got CR after one course of induction chemotherapy was significantly longer than that of patients without CR [7.6 (2.2-44.1) versus 5.8 (1-19.4), (P=0.048)]. The rate of CR in the signal transduction pathway gene mutation group was significantly lower than that in non-mutation group (64.5% vs 100%) (P=0.045), while the level of serum hydroxybutyrate dehydrogenase (HBDH) was significantly higher than that in non-mutation group [(418 (154-2702) vs 246 (110-1068)] (P=0.032). There was no difference in CD56 expression between the two groups (P=0.053), which was limited to the difference between (≥20%) expression and non-expression. (P=0.048).@*CONCLUSION@#CBF-AML patients with signal transduction pathway gene mutation are often accompanied by high HBDH level and CD56 expression, moreover, the remission rate induced by one course of treatment is low.
