Pulse diagnosis system of traditional Chinese medicine is a complicated nonlinear macrosystem.Directed by complexity science theory,and introduced with idea of complex-simple-complex,the pulse diagnosis message is multidimensionally extracted,analyzed with reduced integration,and integrated with upgrade stage and dimension,according to four kinds of attributes "the Position,the Rate,the Shape,the Force".After the digitization,the new kind of pulses diagnosis instrument is manufactured with this mechanism.

Objective: To investigate the prevalence of depression and anxiety among transgender populations and the correlation with defense mechanism, so as to provide the evidence for improving mental health among transgender populations. Methods: Transgender populations that visited Psychosexual Outpatient Department of Beijing Huilongguan Hospital for the first time from December 2020 to December 2021 were enrolled. Participants' demographics, depression, anxiety and type of defense mechanisms were collected using self-designed questionnaires, Self-rating Depression Scale, Self-rating Anxiety Scale and Defense Style Questionnaire (DSQ). Factors affecting depression and anxiety were identified using a multivariable logistic regression model. Results: Totally 126 transgender individuals were enrolled, including 95 men (75.40%) with a mean age of (21.53±4.55) years and 31 women (24.60%) with a mean age of (23.58±5.55) years. The prevalence of depression was 46.83% among participants, including 44.07% of participants with mild depression, 30.51% with moderate depression and 25.42% with severe depression, and the prevalence of anxiety was 26.19% among participants, including 60.61% of participants with mild anxiety, 21.21% with moderate anxiety and 18.18% with severe anxiety. The detection of depression was 54.74% among men and 22.58% among women (P<0.05), and the detection of both depression (62.79% vs. 38.55%, P<0.05) and anxiety (41.86% vs. 18.07%, P<0.05) was significantly higher among transgender populations with self-injury or suicide behaviors than among those without. Multivariable logistic regression analysis showed that immature defense mechanisms increased the risk of depression (OR=1.034, 95%CI: 1.018-1.051) and anxiety (OR=1.031, 95%CI: 1.014-1.049) among transgender populations, while mature defense mechanisms reduced the risk of depression (OR=0.887, 95%CI: 0.832-0.946) and anxiety (OR=0.878, 95%CI: 0.821-0.938) among transgender populations. Conclusions The prevalence of depression and anxiety was 46.83% and 26.19% among transgender populations included in this study. Mature defense mechanisms are beneficial to reduce the risk of depression and anxiety among transgender populations. Key words： transgender population depression anxiety defense mechanism

Objective To investigate the risk factors for coronary artery lesions (CALs) in children with Kawasaki disease (KD) in Lanzhou. Methods One hundred and seventy-four children with diagnosed KD were divided into CAL group and non-CAL group based on the existence of concurrent CALs. The age, gender, fever duration, intravenous immunoglobulin (IVIG) start time, IVIG dose, C-reactive protein (CRP), serum albumin, erythrocyte sedimentation rate (ESR), platelet (PLT), red blood cell count (RBC), hemoglobin and so on were compared. Results Among the 174 children, 46 children (26.44%) were complicated by CALs and 128 children were not. The differences of average fever duration, IVIG starting time, IVIG dose, PLT, CRP, ESR and RBC were statistically signiifcant (P<0.05). Conclusions When KD children has the fever durations>10 d, start of IVIG af-ter 10 days of fever, increase of PLT, CRP and ESR and decrease of RBC, clinicians should be alert to the risk of concurrent CAL.

Objective To evaluate the clinical application of serum CYFRA21-1 detection during the diagnosis of lung cancer. Methods Serum level of CYFRA21-1 in 196 patients with lung cancer and 39 healthy controls were determined by the Elctro-chemiluminescence Immuno-assay ( ECLIA) , respectively. Results Serum level of CYFRA21 -1 ( range from 0. 30 μgg/L to 500.00 μg/L) in patients with lung cancer were significantly higher than those in the healthy control ( range from 0. 27 μg/L to 3. 29 μg/L,Z = -4. 65,P < 0.01). ROC analysis of diagnosis efficiency showed that the area under curve ( AUC) was 0. 735 (P < 0. 001 ). The confidence interval of 95% was from 0. 663 to 0. 807. Positive detection rate of CYFRA21-1 was 48. 8% (39/80) in squamous,31.7% (20/63) in adenocarcinoma and 22. 6% (12/53) in small cell lung cancer (SCLC) respectively, as well as total positive rate was 36. 2% (71/196). Stepwise regression analysis showed that serum level of CYFRA21-1 had a linear correlation with the squamous and the metastasis to liver or bone (r =0. 505 ,P <0. 05). Conclusions Serum level of CYFRA21-1 increases the diagnostic sensitivity, which is helpful for determining histological types, monitoring the metastasis of liver and bone, and evaluating the treatment response in patients with lung cancer.

Objective To design a new cancer vaccine by using alpha-galactosylceramide (α-Galcer,α-GC) loaded tumor cells in combination with TLR 9 ligand and to evaluate its therapeutic effects on colon canc-er in mice.Methods MC38 cells were transfected with lentivirus (GFP-CD1d) to prepare CD1d-MC38 cells. The expression of CD1d molecules in CD1d-MC38 cells was detected by fluorescence microscopy , RT-PCR and flow cytometry.The sorted CD1d-MC38 cells were loaded with α-Galcer to prepare CD1d-MC38/α-GC complex.

Objective:To assess the possibility of suicide in setting condition among urban and rural residents samples in northern China.Methods:By randomly sampling,1007 persons aged 18 years or older were selected from 10 urban neighborhoods in Beijing and from 10 rural village in Hebei province.The Survey Schedule of Atti-tudes in China in which 24 negative life events were listed,and the possibility of committing suicide was asked to the subjects when they encountered the supposed events.Results:The rates of thinking about committing suicide when encountered the supposed life events were 65.2% of incurable illness,62.0% of burden on other and no future hope,61.2% of drug dependence,57.3% of large debt due to gambling,54.2% of being raped, 51.6% of severe depression,50.7% of being elderly and no family to provide support.Only 14.6% of the ur-ban and rural residents would not consider suicide when encountered any type of supposed problems.Conclusion:There is higher possibility of considering suicide in urban and rural residents when encountered negative life events, so it is important to give support to the residents with one or more life events.

Hirudin (HV) is known as the most potent and specific inhibitor of thrombin. Although hirudin has many advantages , it has the bleeding side effect and this is the great shortage of hiudin for clinical application. In order to alleviate bleeding side effect of hirudin, fusion protein, named as FHV (fusion hirudin linked with FXa recognition peptide) was designed. The fusion protein gene ( fhv) was cloned into plasmid pPIC9K. FHV engineered Pichia pastoris containing high copies was chosen for fermentation and purification at 30 L fermentor scale, finally, FHV with purity of above 97% was obtained. To investigate the function of FHV in vivo, mouse tail thrombosis model was used. In the mice thrombus tail model induced by carrageenan, FHV decreased the length of tail thrombus significantly, similar to that of HV control, and had no obvious effects on the TT, PT and APTT. In conclusion, FHV is constructed and expressed in yeast. FHV fusion proteins is obtained by fermentation and purification. FHV has antithrombotic effects not influencing IT, PT and APTT after administration immediately in animal models. Therefore, FHV is a promising anticoagulant and antithrombotic drug.

Objective To investigate clinical features and risk factors for recurrent syncope in children with orthostatic intolerance.Methods Patients with orthostatic intolerance and syncope admitted in the Second Hospital of Lanzhou University from January 2014 to June 2015 were retrospectively analyzed by using t test,Chi -square test,and Fisher′s exact probability method.According to frequency of syncope,all cases were divided into 2 groups,the occasio-nal syncope group and the recurrent syncope group.All risk factors including age,gender,body mass index(BMI),in-ducement,the history of motion sickness,family history,syncope -related injuries,performance of head -up tilt table test,and outcomes of head -up tilt table test were studied statistically and compared within 2 different groups.Results A total of 83 cases were enrolled in this study.Among these children,33 cases(39.76%)were assigned as occasio-nal syncope group,in which 17 cases were male and 16 cases were female and the age ranged from 6 to 18 years with the average age of (9.70 ±2.87)years;50 cases(60.24%)were assigned as recurrent syncope group,in which 27 ca-ses were male and 23 cases were female and the age ranged from 6 to 18 years with the average age of (11.24 ±2.83) years.Of all the investigated risk factors,the BMI and the history of motion sickness were significantly different between 2 groups[(18.84 ±3.49)kg/m2 vs (18.16 ±3.68)kg/m2 ,t =4.82,P =0.001;39.39%(13 /33 cases)vs 70.00%(35 /50 cases),χ2 =7.64,P =0.006].No significant difference was found in age distribution(6 -9 years,10 -14 years,15 -18 years)between 2 groups(P =0.428).There were no significant differences in gender (male /female), family history,or syncope -related injuries between 2 groups[17 /16 cases vs 27 /23 cases;3.03%(1 /33 cases)vs 10.00%(5 /50 cases);15.15%(5 /33 cases)vs 20.00%(10 /50 cases),all P >0.05].And no significant difference was found in inducement (prolonged standing,body posture change,emotional stress/emotional stimuli,muggy environ-ment,movement)between 2 groups [78.79% (23 /33 cases)vs 72.00% (36 /50 cases);9.09% (3 /33 cases)vs 14.00%(7 /50 cases);3.03%(1 /33 cases)vs 6.00%(3 /50 cases);12.12% (4 /33 cases)vs 10.00% (5 /50 cases);3.03%(1 /33 cases)and 12.00%(6 /50 cases),all P >0.05].And performances of head -up tilt table test (blurred vision/blacked out,nausea/vomiting,sweating,dizzy/headache,palpation,anhelation /chest tightness,hot, weak)between 2 groups showed no significant differences[18.18%(6 /33 cases)vs 12.00%(6 /50 cases);36.36%(12 /33 cases)vs 50.00%(25 /50 cases);24.24%(8 /33 cases)vs 26.00%(13 /50 cases);51.52%(17 /33 cases) vs 58.00%(29 /50 cases);6.06%(2 /33 cases)vs 16.00%(8 /50 cases);27.27%(9 /33 cases)vs 22.00%(11 /33 cases);33.33%(11 /33 cases)vs 32.00%(16 /50 cases);12.12%(4 /33 cases)vs 16.00%(8 /50 cases),all P >0.05].Also there were no significant differences in outcomes of head -up tilt table test between 2 groups(P =0.589). Conclusions The risk factors for recurrent syncope in children with orthostatic intolerance were low BMI and the his-tory of motion sickness for such children,and more positive and effective clinical intervention can improve the living quality of children with orthostatic intolerance to some extent.
