Based on the clinical thinking of combining diseases and patterns， we combined disease identification， pattern differentiation， and constitution identification， and put forward the theory of identifying and treating critical hypertension， which is "examining the symptoms first， identifying the constitutions as reference， and combining the diseases and patterns". Firstly， the starting point of identifying the disease is to examine the symptoms， and those with precise diagnosis and strong specificity will be diagnosed with the disease， while those with relatively broad diagnosis and fuzzy characteristics will be emphasised on identifying constitutions and differentiating patterns. Focusing on the impact of constitution identification on disease identification and pattern differentiation， constitution identification could be the basis when no symptoms to identify， and based on the theory of "constitution-disease correlation" and "constitution-pattern correlation" to improve the understanding of borderline hypertension from the group and individual level， which helps to identify and predict the development of the diseases and patterns； if the symptoms are complicated and difficult to identify， it is necessary to take syndrome as the outline， use the syndrome to unify the disease， and then refer to the constitution to legislate and prescribe medications. This paper summarizes the traditional Chinese medicine clinical differentiation and treatment strategy of borderline hypertension clear and easy to grasp， with a view to provide a feasible and efficient reference for prevention and treatment of borderline hypertension with traditional Chinese medicine.

Objective:To explore risk factors for refracture after percutaneous kyphoplasty(PKP)in elderly patients with osteoporotic vertebral compression fractures(OVCF)and provide clinical guidance.Methods:A retrospective analysis was conducted on clinical data from elderly patients with OVCF who underwent PKP surgery at the Department of Orthopedics, Shanxi Bethune Hospital, between January 2017 and December 2022.All patients were followed up for a minimum of one-year post-surgery.The elderly patients were categorized into a refracture group(59 cases)and a non-refracture group(200 cases)based on post-surgery refracture occurrence.Univariate analysis was initially conducted on the collected data, followed by multivariate Logistic regression analysis on statistically significant indicators to identify risk factors for refracture in elderly patients with OVCF following PKP.Results:The results of the univariate analysis indicated that there was no statistically significant difference in gender, history of diabetes mellitus, history of smoking, history of hormone medication, and body mass index(BMI)between the refracture group and the non-refracture group of elderly patients.However, the refracture group was found to be older than the non-refracture group( t=9.085, P=0.003).Additionally, there were no significant differences in preoperative indicators such as preoperative calcium, preoperative phosphorus, and site of first fracture(all P>0.05).The time from first fracture to surgery being greater than 14 days was more common in the refracture group compared to the non-refracture group( χ2=20.409, P=0.001), and the number of vertebrae fractured for the first time was higher in the re-fracture group( t=6.189, P=0.017).Cement injection method, amount of cement injected, and distribution of cement did not show significant differences between the two groups(all P>0.05).However, there were statistically significant variations in the proportion of postoperative anti-osteoporosis treatment( χ2=13.431, P=0.001)and bone mineral density( χ2=13.431, P=0.001)between the refracture and non-refracture groups.Furthermore, multifactorial Logistic regression analysis revealed that increasing age( OR=1.061, 95% CI: 1.021-1.103, P=0.003), time from first fracture to surgery exceeding 14 days( OR=5.026, 95% CI: 1.968-12.835, P=0.001), lack of anti-osteoporosis treatment( OR=3.493, 95% CI: 1.239-9.846, P=0.018), and decreased bone mineral density( OR=10.682, 95% CI: 2.707-42.151, P=0.001)were identified as influential factors in the occurrence of secondary vertebral compression fracture after surgery. Conclusions:The independent risk factors for refracture after PKP in elderly patients with OVCF include increasing age, time from first fracture to surgery greater than 14 days, lack of anti-osteoporosis treatment, and decreased bone mineral density.In clinical practice, targeted interventions can be implemented for prevention and effective management based on these risk factors to enhance the prognosis of elderly patients with OVCF.

BACKGROUND: Men who have sex with men (MSM) have become a high risk population of HIV infection due to their risky sexual behaviors. The latent pattern of psychosocial characteristics plays an important effect in HIV-related risky behaviors among HIV-negative MSM. METHOD: Participants were recruited from Wuhan, Nanchang, and Changsha city from September 2017 to January 2018. Social support was assessed by the multidimensional scale of social support, Connor-Davidson Resilience scale-10 items for reliance, the assessment of Stigma towards Homosexuality for sexual minority stigma, the Likert subscale of nondisclosure for identity concealment, the ACE questionnaire-Kaiser-CDC for adverse childhood experience, the Centers for Epidemiological Studies Depression Scale for depression. Latent profile analysis (LPA) and multivariate regression were used to analyze the data. RESULTS: Three psychosocial characteristic patterns were revealed by the LPA. "Social support and resilience group" (SR group), "Identity concealment group" (IC group) and "Adverse childhood experience" (ACE group) were identified, respectively. In comparison with "SR group", "IC group" have a higher likelihood of one-night male partners (AOR = 2.74, 95%CI = [1.54, 4.90]), both fixed and one-night male partners (AOR = 2.01, 95%CI = [1.34, 3.01]) and HIV-unsure male partner (AOR = 2.12, 95%CI = [1.44, 3.13]). Similarly, "ACE group" were more likely having inconsistent condom use (AOR = 2.58, 95%CI = [1.41, 4.73]), and having sex with HIV-positive male partner (AOR = 4.90, 95%CI = [1.95, 12.30]) with comparison of "SR group". In addition, we further revealed that "ACE group" had a higher ratio (90.0%) of inconsistent condom use among MSM whose male partners were HIV-positive. CONCLUSIONS Six important psychosocial factors were divided into three latent pattern classes. Compared with "SR group", "IC group" and "ACE group" were more likely to engage in HIV-related risky sexual behaviors. Further research may pay more attention to "IC group" and "ACE group" for targeted intervention.

Objective:To explore the characteristics of echocardiographic parameters among the many parameters of two-dimensional transthoracic echocardiography(2D-TTE) and three-dimensional speckle tracking imaging (3D-STI) that can be used for early identification of familial hypertrophic cardiomyopathy(FHCM) mutation gene carriers, and construct a Nomogram prediction model, in order to provide a diagnostic method for early identification of G+ P- patients for clinical practice.Methods:A total of 15 FHCM families admitted to the General Hospital of Ningxia Medical University from November 2017 to August 2022 were enrolled.Whole exome sequencing and Sanger sequencing technology were used for gene detection, among which 54 were G+ P- and 75 were G-P-. Stratified random sampling was used to divide the subjects into training set ( n=90) and test set ( n=39) according to the ratio of 7∶3. Philips iE33 ultrasonic diagnostic instrument and TomTec offline software were used to obtain relevant ultrasonic parameters. Lasso regression and Logistic regression were used to screen echocardiographic parameters and obtain independent risk factors for early prediction of G+ P-, based on which a Nomogram prediction model was established. Results:①Lasso-Logistic regression showed that global longitudinal strain(GLS) ( OR=1.739, 95% CI=1.305-2.316) and left ventricular outflow trac velocity time integral(LVOT-VTI) ( OR=1.358, 95% CI=1.072-1.722) could be used as independent risk factors for early prediction of G+ P-. ②The Nomogram prediction model was established based on the above indicators. After 1000 internal verifications of Bootstrap self-sampling, the C-indices of the training set and the test set were 0.885 (95% CI=0.816-0.954), 0.878 (95% CI=0.764-0.992), which had good internal consistency. ③The results of the calibration curve showed that the risk of G+ P- predicted by the Nomogram model was basically consistent with the actual risk (training set P=0.990, test set P=0.961); the clinical decision curve shows that under different threshold probabilities, using this prediction model to provide patients with clinical decision-making could bring benefits to patients. Conclusions:Echocardiographic parameters GLS and LVOT-VTI can be used as independent risk factors to predict FHCM mutation gene carriers. The Nomogram prediction model has good discrimination, goodness of fit and clinical benefit in identifying whether the family members of FHCM patients carry the mutation gene, and it can provide a new idea and evaluation method for the early identification of FHCM mutation gene carriers by echocardiography.

Objective:To explore the clinical value of coronary artery calcification (CAC) detected by chest CT in early screening of coronary atherosclerotic heart disease (CAHD) in civil pilots.Methods:The physical examination data of 2 899 civil pilots were retrospectively analyzed. Pilots were divided into CAHD group and control group based on the results of coronary angiography (CAG). The health data were compared between 2 groups and the clinical value of CAC in the diagnosis of CAHD was analyzed by using binary Logistic regression model and receiver operating characteristic (ROC) curve.Results:Thirty-eight CAHD cases were diagnosed, and the remaining 2 861 were in the control group. Comparing to that of control group, the average age of the pilots in CAHD group was greater ( t=12.09, P<0.001), and the average total flying hours were longer ( Z=-7.68, P<0.001). The proportions of smoking, hyperlipidemia, diabetes, hypertension, fatty liver, obesity, carotid plaques, positive or suspiciously positive in submaximal treadmill exercise test, CAC, as well as the proportions of taking further requested coronary CT angiography and CAG were significantly higher in the CAHD group ( χ2=5.42-1 430.25, P<0.01 or <0.05). Logistic regression model showed that smoking ( OR=2.800, 95% CI: 1.074-7.301, P=0.035), obesity ( OR=3.336,95% CI:1.243-8.956, P=0.017), positive or suspiciously positive in submaximal treadmill exercise test ( OR=17.669, 95% CI: 2.923-106.756, P=0.002) and CAC ( OR=96.039, 95% CI: 11.439-806.396, P<0.001) were the independent risk factors for diagnosing CAHD. The ROC curve results suggested that the sensitivity and specificity of CAC for predicting CAHD was 97.4% and 93.1%, respectively, and the area under the ROC curve was 0.952 ( P<0.001). Conclusions:CAC detected by chest CT in physical examination is helpful for early screening of asymptomatic or atypical CAHD in civil pilots.

Objective:To analyze the clinical characteristics and outcomes of critically ill pregnant and parturient women in intensive care unit (ICU), and to provide clinical experience for the subspecialty construction of critical obstetrics.Methods:The clinical data of critically ill pregnant and parturient women admitted to the department of critical care medicine, the Second Affiliated Hospital of Kunming Medical University from January 2011 to December 2019 were collected. The main reasons for maternal transfer to ICU, the causes of maternal death, and organ support measures, etc. were summarized.Results:A total of 39 567 critically ill pregnant and parturient women were admitted to the department of obstetrics in our hospital, and 360 were transferred to ICU, with an average ICU transfer rate of 0.91%. Since 2016, the number of obstetric admissions, the number of ICU transfers and the ICU transfer rate had increased significantly. The average age of severe maternals admitted to ICU was (30.9±5.7) years old. The average acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score was 7 (4, 10). The average length of ICU stay was 1 (1, 2) day. The average ventilator duration was 9.0 (3.0, 17.5) hours. The main delivery mode of pregnant women in ICU was cesarean section (84.72%). Forty-eight patients (13.33%) underwent hysterectomy, of which 42 (87.5%) due to postpartum hemorrhage. The top 3 causes of ICU admission were severe postpartum hemorrhage [36.94% (133/360)], hypertensive disorders of pregnancy [21.67% (78/360)], pregnancy with cardiac disease [15.00% (54/360)]. The leading cause of postpartum hemorrhage in women transferred to ICU was placental abnormality [63.98% (103/161)], followed by uterine atony [28.57% (46/161)]. The average blood loss was (4 019±2 327) mL within 24 hours after delivery, and the number of women who underwent hysterectomy due to postpartum hemorrhage decreased year by year. During the study period, there were 2 maternal deaths, which were indirect obstetric deaths, 3 cases were discharged against-advice (expected death), including 1 indirect death and 2 direct obstetric death; the mortality in ICU was 1.39% (5/360).Conclusions:The most common reasons for pregnant and parturient women to be admitted to ICU were severe postpartum hemorrhage and hypertensive disorders of pregnancy. The leading cause of postpartum hemorrhage was placental problem. Indirect obstetric deaths exceeded direct obstetric deaths, mainly due to pregnancy complicated with cardiac disease and severe pneumonia. ICU has become an important battlefield for rescuing critically ill maternal and an important guarantee for reducing the maternal mortality.

Objective : To study the expression and clinical significance of Wnt signal secretory protein DKK1 in cervical cancer. Methods : Reverse transcription polymerase chain reaction (RT⁃PCR) was used to detect the expression of DKK1 mRNA in 30 pairs of cervical cancer tissues and adjacent normal tissues. The expression of DKK1 protein was detected by immunohistochemistry in 60 cases of cervical cancer and 30 cases of normal cervical tissue , and the relationship between the expression and clinicopathological characteristics of cervical cancer was analyzed. Results : The expression of DKK1 in cervical cancer tissues was lower than that in adjacent tissues and normal cervical tissues (P < 0. 05) . The expression of DKK1 was closely related to clinicopathological stage , tissue differentiation , lymph node metastasis and depth of invasion (P < 0. 05) . Conclusion The expression of DKK1 is low in cervical cancer and plays an important role in the occurrence and development of cervical cancer.

Because of the widespread development and application of rapid response system (RRS) in medical institutions in developed countries, such as Europe, America and Australia, the clinical adverse events (cardiac arrest, accidental death, etc.) in hospital patients have been reduced and improved. Meanwhile, the hospitalization rate and mortality rate of intensive care unit in hospital patients have been reduced, thus shortening the hospitalization time and reducing the medical expenses. Nevertheless, RRS is still in the exploration stage in our country. Therefore, the article reviews the RRS model and application development.

Objective:To investigate the relationship between sarcopenia and chronic heart failure(CHF)in the elderly.Methods:In the retrospective study 365 patients aged≥65 years were randomly divided into the CHF group(n=168)and the non-CHF group(n=188). Skeletal muscle mass(ASM) body mass and skeletal muscle mass index(SMI)were measured and compared between the two groups. The correlation between sarcopenia and CHF in the elderly was analyzed.Results:ASM was(15.46±3.02)kg and SMI was(5.12±0.76)kg/m 2in the CHF group which were significantly lower than those in the non-CHF group[(19.87±2.45)kg and(7.23±0.79)kg/m 2 respectively each P<0.01]. The proportion of subjects with sarcopenia in the CHF group was higher than that in the non-CHF group [26.19%(44 cases) vs. 6.38%(12 cases), P<0.01]. Multivariate Logistic regression analysis showed that age( OR=1.87, 95% CI: 1.132 to 2.285 P<0.05) CHF( OR=23.89, 95% CI: 5.394 to 98.842, P<0.01) gender( OR=20.43, 95% CI: 4.294 to 78.324, P<0.01) and body mass index( OR=23.43, 95% CI: 5.328 to 100.786, P<0.01)were risk factors for sarcopenia in elderly patients. Conclusions:CHF is associated with an increased incidence of sarcopenia in elderly patients.
