Guided by the theory of "liver governing the free flow of qi"， it is believed that liver fail to govern the free flow of qi may lead to qi stagnation， phlegm coagulation， and stasis， which is the core pathogenesis of thyroid nodules， breast nodules and uterine fibroids； qi stagnation， phlegm coagulation， and stasis are not only the important pathological products， but also the obstruction to the liver's function， and the two affect each other as the cause of each other. In clinic， it is advocated that using the treatment method of soothing the liver， rectifying qi， and resolving constraint， with prescription of Tongqi Powder （通气散） as the basic formula， and modified according to symptoms. For liver depression and qi stagnation syndrome， the formula chooses modified Tongqi Powder to soothe the liver and rectify qi； for qi stagnation and phlegm coagulation syndrome， the formula chooses modified Tongqi Powder plus Shenling Baizhu Powder （参苓白术散） to soothe the wood and regulate the earth， and resolve phlegm and dissipate masses； for qi stagnation and blood stasis syndrome， the formula applies modified Tongqi Powder plus Taohong Sizu Decoction （桃红四物汤） to move qi and invigorate blood circulation， unblock the collaterals and dispel accumulation. At the same time， according to the characteristics of thyroid nodules， breast nodules， and uterine fibroids and their different disease locations， medicinals were added or subtracted according to the symptoms， so as to treat both the symptoms and the root cause of the disease simultaneously.

This paper discussed the current education status on medical ethics and styles and the assessment condition in the examination of doctors' qualification， as well as the existing problems and potential solutions by reviewing domestic and foreign literature and summarizing the practice experience. Traditionally， medical ethics and styles have always been integrated into clinical medical practice in China. However， under the modern medical education system， it is challenged to integrate traditional education on medical ethics and styles with the rules of modern medical knowledge. By summarizing the education and assessment status of medical ethics and styles in the examination of doctors' qualification， it is found that the current examination is relatively poor in the evaluation content， and the way of evaluation is not diverse， with lack of curriculum of medical humanities. The solutions suggested are enriching relevant examination content， introducing more and comprehensive evaluation method， and establishing more medical humanities-related courses.

Objective:To explore the association between changes in brain structural network during the early stage of stroke recovery and the onset of post-stroke depression (PSD).Methods:A total of 87 acute ischemic stroke patients scheduled for discharge, who were admitted to the Yixing Hospital Affiliated to Jiangsu University from March 2020 to May 2021, were prospectively collected. During the same period, 34 healthy control subjects matched with the stroke patients were also collected. All participants underwent systematic magnetic resonance imaging scans and scale assessments, and were followed up longitudinally for 2 years. Based on the occurrence of depression during follow-up, the stroke patients were divided into PSD group and post-stroke non-depression (PSND) group. Graph theoretical analysis was used to analyze the topological characteristics of brain structural network. Analysis of variance was used to explore the differences in brain structural network attributes among groups. Logistic regression model was used to analyze the predictive power of differential brain network attributes for PSD. Linear regression analysis was conducted to investigate the relationship between the synergism of non-rich-club regions and changes in rich-club connectivity.Results:The rich-club connectivity and synergism of the non-rich-club regions were significantly lower in the PSD group than in the PSND group (rich-club connectivity, P<0.01; synergism of feeder/local, P<0.001). The regression model demonstrated that the synergism of non-rich-club regions had a good predictive power for the occurrence of PSD ( OR=1.195, 95%CI 1.073-1.471, P<0.001). Furthermore, linear regression analysis revealed a significant correlation between the synergism of non-rich-club regions and Δrich-club connectivity ( r=-0.691, P<0.001). Conclusion:The good synergism of non-rich-club regions during the early stage of stroke recovery promotes the repair of rich-club connectivity and inhibits the onset of PSD.

Objective:To investigate the features of the brain structural network in patients with postpartum depression (PPD).Methods:This cross-sectional study included PPD patients who visited the mental health counseling clinic after delivery at the Jiangsu University Affiliated Yixing Hospital from June 2013 to September 2022 (PPD group). Matched non-PPD postpartum women based on age, years of education, and body mass index who came for postpartum follow-up (non-PPD postpartum group), and non-pregnant women who visited the hospital or underwent physical examinations during the same period (non-pregnant group) were also included. Demographic data and diffusion tensor imaging (DTI) data were collected for all three groups. The brain was partitioned into 90 regions using an anatomical template to construct the brain structural network. Network-based statistics (NBS) were applied to further screen and construct subnetworks. The efficacy of the subnetworks in identifying PPD was evaluated through multivariable logistics regression models and receiver operating characteristic curves. A comparison of the connectivity strength of white matter tracts and topological attributes of brain structural network parameters was conducted using independent samples t-tests, and the results were corrected using the false discovery rate (FDR) method. Results:(1) A total of 116 subjects were included, with 40 in the non-pregnant group, 40 in the non-PPD postpartum group, and 36 in the PPD group. PPD group had higher Edinburgh Postnatal Depression Scale (EPDS) scores than the non-pregnant and non-PPD postpartum groups [(18.0±4.1) scores vs. (2.5±1.2) and (6.1±2.1) scores, F=340.40; t=24.65,10.60 and 16.16 in pairwise comparison; all P<0.001]. (2) Compared to the non-pregnant group, there was a decrease in the connectivity strength of nine white matter tracts within the brain structural network of the postpartum group (including left dorsolateral superior frontal gyrus-left anterior cingulate and paracingulate gyrus, left dorsolateral superior frontal gyrus-right amygdala, left dorsolateral superior frontal gyrus-left insula, left insula-left lentiform nucleus, left insula-left hippocampus, left hippocampus-right amygdala, left hippocampus-left precuneus, left anterior cingulate and paracingulate gyrus-right amygdala, and right amygdala-right hippocampus) (all P<0.05, FDR corrected). No increased connection strengths were observed. There were no significant differences in the connection strengths of these nine tracts between the non-PPD and PPD groups. (3) A characteristic subnetwork for the maternal group was successfully constructed based on the nine tracts, which exhibited typical small-world properties (σ>1). Compared to the non-PPD maternal group, the characteristic path length in the PPD group was increased [(3.904±0.328) vs. (4.130±0.433), t=－2.58], and global efficiency was decreased [(0.361±0.036) vs. (0.331±0.053), t=2.91] (both P<0.05). Local property comparisons showed that the node efficiency values for the left dorsolateral superior frontal gyrus, left insula, left anterior cingulate and paracingulate gyrus, left hippocampus, right hippocampus, right amygdala, left precuneus and left putamen in the PPD group were significantly reduced [(0.273±0.023) vs. (0.267±0.030), t=0.98; (0.299±0.035) vs. (0.276±0.041), t=2.64; (0.265±0.019) vs. (0.258±0.025), t=1.38; (0.318±0.028) vs. (0.305±0.031), t=1.92; (0.312±0.027) vs. (0.302±0.031), t=1.50; (0.322±0.030) vs. (0.298±0.026), t=3.71; (0.356±0.040) vs. (0.338±0.056), t=1.62; (0.346±0.028) vs. (0.331±0.036), t=1.74; all P<0.05]. However, only the differences in node efficiency values for the left insula and right amygdala remained significant after FDR correction (corrected P=0.041 and 0.003). (4) Global efficiency, as well as node efficiency for the left insula and right amygdala, demonstrated good value for identifying PPD [areas under the curve (AUC) and their 95% CI were 0.827 (0.732-0.922), 0.741 (0.628-0.854), and 0.761 (0.653-0.867), respectively], with even better performance when combined [0.897 (0.828-0.969)]. (5) In the PPD group, global efficiency ( r=－0.43, P=0.008), node efficiency for the left insula ( r=－0.39, P=0.019), and node efficiency for the right amygdala ( r=－0.42, P=0.011) were all negatively correlated with EPDS scores. Conclusion:Aberrations in global efficiency, node efficiency for the left insula, and node efficiency for the right amygdala may serve as characteristic neuroimaging biomarkers for PPD.

Objective:To investigate the pathological subtypes and clinicopathological characteristics of the non-squamous immunophenotype nasopharyngeal carcinoma (NSNPC).Methods:The clinicopathological features of the non-squamous immunophenotype nasopharyngeal carcinoma diagnosed between 2011 and 2019 at the First Affiliated Hospital of Zhengzhou University were analyzed using hematoxylin and eosin staining, immunohistochemistry, in situ hybridization, transmission electron microscopy and PCR gene rearrangement. Follow-up data were also collected.Results:There were 14 males and 9 females with a median age of 46 years (ranging from 16 to 76 years) with an average age of 45 years. Microscopically, patterns were similar to the classic nasopharyngeal carcinoma. Immunohistochemistry showed that most NSNPC cases expressed low molecular weight keratin (CK8/18, CK8 and CKL) and expressed pathway proteins in a low level (EGFR, PI3K, p-AKT and p-mTOR), which had significant difference from classic nasopharyngeal carcinoma group ( P<0.05). Other proteins including CK5/6, CKpan, CK7, Syn, CD56, CgA, SOX-10, AKT, mTOR, Notch, STAT3 and p-STAT3 showed no statistical difference between the two groups. Pathogen detection showed that EBER was positive (18/23, 78.3%) and HPV positive(2/23, 8.7%)which were HPV35 and HPV38. The cancer suppressor gene BLU was highly expressed in NSNPC; RASSF1 and Rbms3 were less expressed in NSNPC, in line with classic NPC. As a whole, NSNPC was characterized by ultrastructures of low-differentiated squamous cell carcinoma. Compared with classic nasopharyngeal carcinoma, NSNPC had a lower recurrence rate and earlier clinical stage( P<0.05),but there was no significant correlation with age, sex, distant metastasis and death ( P>0.05). Conclusions:The histological morphology, etiology and gene changes of NSNPC are similar to those of classical nasopharyngeal carcinoma and ultrastructural findings show that NSNPC still belongs to undifferentiated type in non-keratinized squamous cell carcinoma. The malignant degree of NSNPC is low and the prognosis is good.

Objective:To explore the distribution characteristics of respiratory pathogens in patients with community-acquired pneumonia in Lianyungang.Methods:A total of 612 patients admitted to the second people′s Hospital of Lianyungang City because of community-acquired pneumonia (CAP) in 2019 were selected as subjects. Sputum or pharyngeal swabs were collected to extract nucleic acids, and 13-fold nucleic acids of respiratory pathogens were detected by PCR capillary electrophoresis fragment analysis. SPSS statistical software and GraphPad5.0 statistical mapping software were used for statistical analysis.Results:The physical examination rate of respiratory pathogens in the adult group was 82.0% in winter, 48.4% in spring, 28.0% in autumn, 20.0% in summer, χ 2=38.473, P=0.000. The positive rate of nucleic acid detection was significantly different in different seasons, among which the physical examination rate of respiratory pathogens in winter was the highest. The physical examination rate of respiratory pathogens in the juvenile group was 86.0% in spring, 76.2% in winter, 71.3% in summer and 66.7% in autumn, χ 2=7.946, P=0.047 . The positive rate of nucleic acid detection was calculated according to gender grouping. The comparison of nucleic acid positive rate between adult group and juvenile group in different seasons: 86.0% vs 48.4% in spring, χ 2=19.436, P=0.000; 71.3% vs 20.0% in summer, χ 2=22.180, P=0.000; 66.7% vs 28.0% in autumn, χ 2=13.485, P=0.000; 76.2% vs 82.0% in winter, χ 2=0.758, P=0.384. Except in winter, the detection rate of nucleic acid of pathogens in the juvenile group was significantly higher than that in the adult group. Conclusions:The nucleic acid detection rate and etiological distribution characteristics of respiratory pathogens are different in patients with community-acquired pneumonia in different seasons and different age groups. 13 kinds of multiple detection methods of respiratory pathogens can provide favorable laboratory data support for the diagnosis and treatment of clinical CAP patients.

【Objective】 To explore a method to accurately identify the specificity of alloantibodies or autoantibodies in autoimmune hemolytic anemia (AIHA)patients with both warm and cold antibodies, so as to provide guidance for the selection of blood components. 【Methods】 Blood samples of AIHA patients with both warm and cold antibodies were screened by the direct antiglobulin testing (DAT). The plasma of patients were treated with dilution or adsorption method and the erythrocyte was dispersed for specificity identification of alloantibodies or autoantibodies.According to the results of antibody identification, appropriate phenotype of red blood cells(RBCs) were transfused to patients, and the incidence of adverse reactions and efficacy of transfusion were observed. 【Results】 Alloantibodies or specific autoantibodies were detected in serum or elution in 14 of the 16 patients. 10 patients underwent blood transfusion during hospitalization, and all of them received RBCs with the same or compatible ABO/Rh (D) type as the patients and without any reaction to the alloantibodies and specific warm autoantibodies. No hemolytic reaction occurred, and anemia symptoms were improved after blood transfusion. 【Conclusion】 The selection of appropriate methods could eliminate the influence of autoantibodies on the identification of alloantibodies in AIHA patients with both warm and cold antibodies. Therefore, the selection of blood from compatible donors for transfusion could effectively avoid the occurrence of hemolytic reaction.

Objective: To investigate the current bedtime routine among Chinese children less than 3 years of age and explore its dose-dependent association with sleep duration and sleep quality. Method: Healthy full-term born children aged 0-35 months were selected by stratified cluster random sampling method from 8 provinces in China following the "Hospital of Province-City-County" sampling technical route during 2012-2013.Brief Infant Sleep Questionnaire(BISQ) was used to assess sleep conditions of these children.Children′s personal and family information was obtained by Shanghai Children′s Medical Center Socio-demographic Questionnaire.Both of these questionnaires were filled in by parents. The effects of bedtime routine on children′s sleep duration and quality were analyzed by multivariate analysis of variance. Result: The children′s average age was(12±10) months(n=1 304), of whom 689 were males (52.8%, 689/1 304). There were 48.5%(632/1 304)of the parents reported that their children had not established regular sleep routines. There was a consistent dose-dependent association between bedtime routine and sleep duration, as well as other indicators for sleep quality (all P<0.05). The more regular the sleep routines, the longer the sleep duration, the earlier the children went to sleep, the shorter the sleep onset latency, the fewer the nighttime wakeup and the shorter the nighttime waking.The nighttime sleep duration was significantly longer for those with a bedtime routine 'every night’ than those who 'never’ had a bedtime routine (9.5(95%CI: 9.4-9.6)vs. 8.9(95%CI: 8.6-9.3)h, t=3.345, P=0.001). Compared with children who never had bedtime routines, children with regular bedtime routines had fewer night wakeup (1.3(95%CI: 1.2-1.4) vs. 2.4( 95%CI: 2.0-2.9), t=3.182, P=0.001) and shorter night waking duration(16.6(95%CI: 14.6-18.8) vs. 59.2 (95%CI: 47.0-72.7)min, t=6.383, P<0.01). Conclusion The percentage of children who have established regular bedtime routine is low in China. There is significant dose-dependent association between regular bedtime routine and sleep outcomes, especially sleep quality. The more regular the sleep routines, the better the sleep quality.

Objective To compare the effects of fluid therapy by "measurement" water dispenser and routine fluid therapy on standard fluid therapy among patients with percutaneous coronary intervention (PCI) in coronary care unit (CCU). Methods A total of 204 patients with PCI were divided into observation group (n=102) and control group (n=102) by random number table. Patients in the observation group received drinking water plan according to regulatory requirements using the self-designed "measurement" water dispenser. Patients in the control group accepted nursing plan of routine drinking fluid therapy. This study compared the qualified rate of standardized drinking water, patient satisfaction, renal function and the incidence of contrast-induced nephropathy (CIN) three days after intervention between two groups. Results There were 102 (100.00%) qualified patients drinking water according to stipulations in the observation group, while there were 68 (66.67%) in the control group. The qualified rate of drinking water in the observation group was higher than that in the control group with a significant difference (χ2=38.4, P<0.01). There were two patients with contrast induced nephropathy in the observation group, and eight patients with contrast induced nephropathy in the control group (χ2=4.2,P=0.04). Conclusions The effect of fluid therapy by "measurement" water dispenser supplemented with diversified education is satisfactory among patients with PCI in CCU.

Objective To explore the application value of the situation-background-assessment-recommendation(SBAR) communication mode in the patients with acute myocardial infarction (AMI).Methods Ninety-four cases of AMI patients who were hospitalized in the department of cardiology in Wuxi No.2 People's Hospital of Nanjing Medical University were included and were randomly divided into the conventional group and the SBAR group. There were 47 cases in each group. The patients in the conventional group were given the routine care; the patient in the SBAR group was given the SBAR communication mode. The nursing satisfaction and the incidence of adverse events in the 2 groups were compared.Results The nursing satisfaction in the SBAR group was 95.74%, which was significantly higher compared to the conventional group (70.21%,P<0.05). The total incidence of adverse events in the SBAR group was 4.25%; in the conventional group the incidence was 25.53%. The difference between the 2 group was significant (χ2=6.42,P<0.05).Conclusions The SBAR communication model can effectively improve the quality of the nurses' disease observation and the nursing satisfaction and reduce the incidence of clinical adverse events, which was worth clinical promotion.
