Objective To investigate the impact of microvascular obstruction (MVO) on the global and regional myocardial function by cardiac magnetic resonance feature-tracking (CMR-FT) in ST-segment-elevation myocardial infarction (STEMI) patients after percutaneous coronary intervention.Methods Consecutive acute STEMI patients who underwent cardiac magnetic resonance imaging 1 - 7 days after successful reperfusion by percutaneous coronary intervention treatment were included in this retrospective study. Based on the presence or absence of MVO on late gadolinium enhancement images, patients were divided into groups with MVO and without MVO. The infarct zone, adjacent zone, and remote zone were determined based on a myocardial 16-segment model. The radial strain (RS), circumferential strain (CS), and longitudinal strain (LS) of the global left ventricle (LV) and the infarct, adjacent, and remote zones were measured by CMR-FT from cine images and compared between patients with and without MVO using independent-samples t-test. Logistic regression analysis was used to assess the association of MVO with the impaired LV function.Results A total of 157 STEMI patients (mean age 56.66 ± 11.38 years) were enrolled. MVO was detected in 37.58% (59/157) of STEMI patients, and the mean size of MVO was 3.00 ±3.76 mL. Compared with patients without MVO (n =98 ), the MVO group had significantly reduced LV global RS (t= -4.30, P < 0.001), global CS (t= 4.99, P < 0.001), and global LS ( t= 3.51, P = 0.001). The RS and CS of the infarct zone in patients with MVO were significantly reduced (t= -3.38, P = 0.001; t= 2.64, P = 0.01; respectively) and the infarct size was significantly larger (t= 8.37, P < 0.001) than that of patients without MVO. The presence of LV MVO [OR= 4.10, 95%CI: 2.05 - 8.19, P<0.001) and its size [OR=1.38, 95%CI: 1.10-1.72, P=0.01], along with the heart rate and LV infarct size were significantly associated with impaired LV global CS in univariable Logistic regression analysis, while only heart rate (OR=1.08, 95%CI: 1.03 - 1.13, P=0.001) and LV infarct size (OR=1.10, 95%CI: 1.03 - 1.16, P=0.003) were independent influencing factors for the impaired LV global CS in multivariable Logistic regression analysis.Conclusion The infarct size was larger in STEMI patients with MVO, and MVO deteriorates the global and regional LV myocardial function.

Triglyceride (TG) , total cholesterol (TC) , high density liptein cholesterol (HDL-C) , low density lipoprotein (LDL-C) , IL-6, and TSH were compared between groups, and statistically significant indexes were included for multivariate analysis of the occurrence of DTC. The sensitivity, specificity and optimal cut-off value were analyzed, and their relationship with the clinicopathological characteristics of DTC patients was analyzed.Results:Serum TSH and IL-6 levels from high to low were malignant group, benign group and control group, and HDL-C levels from high to low were control group, benign group and malignant group ( P<0.05) . There was no significant difference in the levels of TC, TG or LDL-C ( P>0.05) . Multivariate Llogistics regression analysis indicated that TSH and IL-6 may be risk factors for the occurrence of differentiated thyroid cancer (all OR>1, P<0.05) . HDL-C may be a protective factor for the occurrence of differentiated thyroid cancer ( OR<1, P<0.05) . The ROC curve was drawn to determine the optimal cut-off value of TSH for the diagnosis of differentiated thyroid cancer, AUC: 0.985, sensitivity was 93.25%, specificity was 96.34%, 95% CI: 0.949-1.000 ( P<0.001) ; the best cut-off value of IL-6 for the diagnosis of differentiated thyroid cancer was 48.96 ng/L, AUC: 0.980, sensitivity was 96.98%, the specificity was 91.53%, 95%CI: 0.956-1.000 ( P<0.05) ; the best cut-off value of HDL-C for the diagnosis of differentiated thyroid cancer was 1.441 mmol/L, AUC: 0.0.691, the sensitivity was 85.10%, the specificity was 48.06%, 95%CI: 0.563-0.812 ( P<0.05) . The serum levels of TSH and IL-6 in patients with lymph node metastasis were significantly higher than those in patients without lymph node metastasis, and the level of HDL-C was significantly lower than those in patients without lymph node metastasis ( P<0.05) . TNM staging The serum levels of TSH and IL-6 in patients with stage III and IV were significantly higher than those in patients with stage I and II, and HDL-C was significantly lower than that in patients with stage I and II ( P<0.05) . Conclusions:Serum IL-6, TSH and HDL-C are closely related to the occurrence of differentiated thyroid cancer. The detection of serum IL-6, TSH and HDL-C is helpful for the differentiation of benign and malignant thyroid nodules. The presence or absence of lymph node metastasis in patients with differentiated thyroid cancer is related to TNM staging, and the detection value is high.

Objective:To explore and analyze the relationship between serum KLK11 and MK levels and the effect of first iodine 131 ( 131I) ablation after operation for differentiated thyroid cancer. Method:108 patients with differentiated thyroid cancer who underwent total thyroidectomy in our hospital from Jun. 2020 to Jun. 2021 were consecutively selected, and received radioactive ablation after surgery. There were 37 males and 71 females. The age was (48.32±4.25) years, ranging from 28 to 79 years. The patients were divided into successful ablation according to whether the ablation was successful after treatment. There were 64 cases in the group and 44 cases in the unsuccessful group, and 60 healthy people with no abnormality in physical examination during the same period were selected as the control group. The patients were divided into a metastasis-positive group of 20 cases and a metastasis-negative group of 88 cases according to whether lymph nodes occurred. After surgery, serum samples of all subjects were taken, and enzyme-linked immunosorbent assay was used to detect the levels of serum kallikrein-related peptidases 11 (KLK11) and midkine (MK) , and the levels of serum KLK11 and MK were analyzed. Gender, age, BMI, TNM stage, TSH, maximum diameter of lesion, and duration of nail removal were collected. Univariate analysis and logistic regression analysis were used to analyze the independent risk factors of postoperative efficacy.Result:The levels of serum KLK11 and MK in the successful and unsuccessful groups were higher than those in the control group, while the levels of KLK11 and MK in the unsuccessful group were higher than those in the successful group (KLK11: t= 2.642, P<0.05; MK: t=11.906, P<0.05) . The serum levels of KLK11 and MK in the metastasis-positive group were higher than those in the metastasis-negative group (KLK11: t= 2.908, P<0.05; MK: t=14.907, P<0.05) . Univariate analysis showed that BMI ( χ2=6.780, P=0.009) , maximum diameter of lesions ( χ2=14.819, P=0.001) , TSH ( χ2=13.627, P=0.001) , serum KLK11 ( t=2.642, P=0.01) , and serum MK ( t=11.906, P<0.001) were associated with the effect of first 131I ablation after surgery for differentiated thyroid cancer ( P<0.05) . Taking the success of ablation as the dependent variable, a multivariate logistic regression analysis was performed. The results showed that the maximum diameter of the lesions greater than 2 cm ( OR=10.740, 95%CI: 7.033-16.401) , increased level of TSH ( OR=8.559, 95%CI: 2.812-26.057) , increased serum KLK11 level ( OR=16.710, 95%CI: .548-32.666) and increased serum MK level ( OR=10.580, 95%CI: 6.294-17.786) were the factors affecting the first 131I ablation effect after DTC surgery ( P<0.05) . Conclusion:The elevated levels of serum KLK11 and MK are independent risk factors affecting the efficacy of the first 131I ablation after surgery for differentiated thyroid cancer.

"Four in one" is a research idea of identifying the classic prescriptions from the following four dimensions: "nature, location, tendency, and syndrome". The multi-dimensional analysis of the mechanism of classic prescription Zhigancao Tang in treating coronary heart disease helps to understand the syndrome differentiation and treatment thoughts of ZHANG Zhong-jing. The coronary heart disease results from deficiency. The efficacy of Zhigancao Tang in treating coronary heart disease can be elucidated from the "nature,location,tendency, and syndrome". In terms of nature, Zhigancao Tang is pungent and sweet in flavor and warm in property, with the sweet responsible for tonifying deficiency, the pungent for dispersing Yang, resolving Yin, and eliminating surplus pathogen, and the warm for moving Yangqi, nourishing blood, and promoting blood circulation. In terms of location, Zhigancao Tang mainly acts on vessels for restoring the normal circulation of blood in the vessels and improving coronary artery stenosis and the resulting ischemia and anoxia. In terms of tendency, Zhigancao Tang tends to affect the upper and inner parts of the body to tonify deficiency in Zangfu organs, promote fluid production, nourish nutrient blood, and dissipate cold simultaneously, thus alleviating chest impediment. In terms of syndrome, Zhigancao Tang is applicable to fluid exhaustion with blood dryness and Yin-yang-qi-blood deficiency syndrome, manifested as regularly or irregularly intermittent pulse and severe palpitation. Zhigancao Tang has been widely used for the treatment of over 70 diseases classified into 10 systems, especially the cardiovascular diseases, in traditional Chinese medicine (TCM) and western medicine. As the “one” of “four in one”, Zhigancao Tang is composed of multiple Chinese herbs and its therapeutic effect is superior to the sum of its parts. It ameliorates the coronary heart disease by resisting inflammation, protecting against ischemia-reperfusion injury, adjusting the ion channels of myocardial cells, and participating in atrial remodeling and hematopoiesis. Its mechanism and clinical efficacy in the treatment of coronary heart disease have been verified by clinical and experimental studies. The utilization of the thought of "four in one" to analyze classical prescriptions enables the combination of prescriptions with syndromes, which is of great significance to the clinical application and modern development of classical prescriptions.

BACKGROUND@#Colorectal cancer (CRC) is the second most common cause of cancer-related deaths and has the third highest incidence in the world. Almost half of the patients with CRC have metastases at the time of diagnosis. However, the treatment for patients with metastatic CRC that progresses after approved conventional chemotherapy is still controversial. Chinese medicine (CM) has unique characteristics and advantages in treating metastatic CRC.@*OBJECTIVE@#To assess the effectiveness and safety of CM in patients with metastatic CRC after failure of conventional chemotherapy.@*METHODS@#The study is a multicenter prospective cohort study. A total of 384 patients with documented metastatic CRC after failure of conventional chemotherapy will be included from 9 hospitals among Beijing, Shanghai, Nanjing, and Guizhou, and assigned to three groups according to paitents' wishes: (1) integrated Chinese and Western medicine (ICM) group receiving CM herbal treatment combined with Western medicine (WM) anti-tumor therapy, (2) Chinese medicine (CM) group receiving only CM herbal treatment, and (3) WM group receiving only WM anti-tumor therapy. The primary endpoint is the overall survival (OS). Secondary endpoints include the progression free survival (PFS), quality of life (QOL) assessed by the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) questionnaire, tumor control, and CM symptom score.@*DISCUSSION@#This prospective study will assess the effectiveness and safety of CM in treating metastatic CRC after conventional chemotherapy failure. Patients in the ICM group will be compared with those in the WM group and CM group. If certified to be effective, national provision of CM treatment in metastatic CRC will probably be advised.

Salvia plebeia has been in use as traditional Chinese medicine (TCM) for more than 500 years. In this study, the complete chloroplast (cp) genome of S. plebeia was sequenced, assembled and compared to those of other five published Salvia cp genomes. It was found that the cp genome structure of S. plebeia was well conserved and had a total size of 151 062 bp. Four parameters were used to display the usage conditions of the codons of the amino acids in Salvia genus. Although the number of protein-coding genes in each species was the same, the total number of codons was different. Except for amino acids Trp and Met whose Relative Synonymous Codon Usage (RSCU) value of one condon was equal to 1, the remaining 19 amino acids had 1-3 preferred codons. The preferred codon names of each amino acid were coincident. The period size for the tandem repeats of six species ranged from 9 to 410 bp. Salvia cp genomes mainly possessed tandem repeats with a copy number less than or equal to 3. The sequence length of tandem repeats of the six species ranged from 25 to 824 bp. Highly viarable regions including four intergenic spacers and six partial genes were discovered as potential specific barcodes for Salvia species through cp genome-wide comparison. Finally, we performed phylogenetic analyses based on the complete cp genome and coding sequences respectively. These results provide information to help construct the cp genome library for Salvia, which may support studies of phylogenetics, DNA barcoding, population and transplastomics.

Enzyme-linked immunosorbent assay(ELISA) and metabolomics were used to analyze and compare two animal models of heart-kidney insomnia, in order to explore a more ideal animal model and preliminarily explore the essence of heart-kidney insomnia. Based on the clinical symptoms and disease characteristics of heart-kidney insomnia, the animal model of heart-kidney insomnia was reproduced through intraperitoneal injection with p-chlorophenylalanine(PCPA) and multi-factor interaction. The animal model of disease-syndrome combination was evaluated by behavioral observation, ELISA and metabolomics. Wistar rats were randomly divided into normal group, PCPA group and compound model group(FH). The rats' behavior, body weight, adrenal index and spleen index were recorded. The levels of corticotropin releasing hormone(CRH) and adrenocorticotropin(ACTH) in serum were detected by ELISA, and the differential metabolites in serum were detected by UPLC-QE-MS. The body weight and adrenal index in FH group were significantly lower than those in PCPA group(P<0.05); whereas ACTH and CRH in FH group were significantly higher than those in PCPA group by ELISA; nine potential biomarkers were identified by serum sample statistics. There were four main metabolic pathways in cardiorenal insomnia: pentose phosphate metabolism, alanine, aspartic acid and glutamic acid metabolism, histidine metabolism, and taurine and subtaurine metabolism. PCPA and multi-factor interaction method can successfully replicate the insomnia model, but multi-factor modeling method is more similar to clinical traditional Chinese medicine syndrome. Animal behavior, ELISA and metabolomics were used to evaluate the rat model of cardiorenal insomnia from in vitro to in vivo, from macro to micro, and from individual to the whole.

A method of high performance liquid chromatography coupled with time-of-flight mass spectrometry was used to detect the endogenous metabolites changes in plasma of normal rats, rats of dampness stagnancy due to spleen deficiency and Astragalus flavone component intervention rats. Metabolism map of rat plasma was obtained and the mechanism of Astragalus flavonoids on dampness stagnancy due to spleen deficiency was studied. Rat model with dampness stagnancy due to spleen deficiency was established by high fat and low protein diet plus load swimming. Liquid chromatography tandem mass spectrometry was used for the analysis of rat plasma sample, and 0.05% formic acid water with 0.05% formic acid acetonitrile as the mobile phase was applied in gradient elution with Halo C18 chromatographic column. In this study, partial least squares discriminant analysis and variance analysis were used to screen the potential biomarkers, it was found that the metabolic profile of the Astragalus flavonoids was different from that of the model group, which was close to that of the normal group. A total of 11 potential biomarkers were identified, including glycerol phospholipids, sphingolipids, amino acids, and so on. The metabolic pathways of biomarkers including three tricarboxylic acid cycle, glycerol phospholipid metabolism, fatty acid metabolism, amino acid metabolism and so on, which mainly related to energy metabolism and fat metabolism in the body. Related indexes of rats with syndrome of spleen deficiency of water and dampness were significantly callback after Astragalus flavone intervention, including macro indicators such as body weight, independent activities and micro indicators such as metabolic markers, blood lipids and others. The result showed that Astragalus flavonoids played the role of strengthening the spleen and draining the water mainly through regulating the energy metabolism, fat metabolism and so on.

Atherosclerosis is the pathological basis of ischemic stroke. Peripheral blood leukocytes are involved in the occurrence and progression of atherosclerosis and cause vascular endothelial injury. A series of changes of peripheral immune cel take place after acute ischemic stroke and cause inflammatory cel infiltrating into the brain tissue. The elevated leukocyte count is closely associated with the occurrence and prognosis of coronary atherosclerotic heart disease. Studies have also shown that the elevated leukocyte count may influence the occurrence of ischemic stroke, neurological deficit, recurrence, and death. This article reviews the relationship between peripheral blood leukocytes and ischemic stroke.

Objective To investigate the feasibility, safety and clinical effect of percutaneous transhepatic bipolar radiofrequency catheter ablation in treating malignant obstructive jaundice. Methods Twenty patients with inoperable malignant biliary obstruction were enrolled in this study. Of the 20 cases , 2 had biliary stent re-occlusion. Percutaneous transhepatic bipolar radiofrequency catheter ablation was carried out in all patients. The ablation power was 5 - 12 W, single ablation time was 60 - 120 s, the average duration of ablation was 4.66 min (1.5 - 8.5 min), and the mean effective ablation extent was 5.76 cm (4 -10 cm). After ablation, balloon catheter was inserted to dilate the occluded segment, which was followed by implantation of biliary metal stent. The clinical efficacy , safety and complications were recorded. Results Percutaneous transhepatic bipolar radiofrequency catheter ablation was successfully completed in all the 20 patients. Implantation of biliary metal stent was performed in 17 patients , among them balloon dilatation was employed in 11 patients before stent implantation , simple balloon dilatation with no stent implantation was employed in one patient, and ablation was adopted after biliary stent re-occlusion occurred in two patients. After the ablation, no complications such as biliary fistula, biliary tract infections, liver penetrating injuries, peritonitis, etc. occurred. Biliary drainage was successfully completed in all patients. The median follow-up period was three months(0.5-10 months); the stent patency rate at the end of one and three months was 100% (19/19) and 79% (11/14) respectively. The one-month and 3-month survival rate was 95% (19/20) and 93% (14/15) respectively. During the follow-up period, 8 of the 20 patients were alive and 12 died. The median survival time was 144 days (13 - 330 days) and the median time of stent patency was 60 days (30-210 days). Of the 12 fatal patients, 8 died of cachexia with multi- system failure although their total bilirubin level was not elevated during the follow- up period. Conclusion For the treatment of malignant obstructive jaundice, percutaneous transhepatic bipolar radiofrequency catheter ablation is a newly-developed, safe and feasible means. Clinically, this technique has already achieved some certain effect although its long-term results need to be further evaluated.

<p><b>OBJECTIVE</b>To investigate the effect of blood-activating Chinese medicinal compounds and water-draining Chinese medicinal compounds on tumor necrosis factor alpha (TNF-α) and nuclear factor kappaB (NF-κ B) expressions in rats with intracerebral hemorrhage (ICH) at the acute stage, and to monitor their therapeutic effect and mechanism of action on inflammation and cerebral edema.</p><p><b>METHODS</b>A rat model of cerebral hemorrhage was achieved by injecting autologous arterial blood into the caudate nucleus. A total of 168 rats were randomly divided into 4 groups: blood-activating medicine group (n=42), water-draining medicine group (n=42), sham operated group (n=42), and the model group (n=42). A series of brain samples were obtained at days 1, 3 and 5 after ICH from rats in all groups. Protein expression levels of TNF-α and NF-κ B were measured by immunohistochemical staining and gene expression levels of TNF-α and NF-κ B were measured by real-time fluorescent PCR.</p><p><b>RESULTS</b>Compared to the sham operated group, protein expression levels of TNF-α and NF-κ B in the model group significantly increased (P<0.01). Protein and gene expressions of TNF-α from the blood-activating medicine group and water-draining medicine group significantly decreased when compared to those in the model group P<0.05). Meanwhile, compared to the model group, the expression of NF-κ B in the blood-activating medicine group significantly decreased (P<0.05), while expression of NF-κ B in the water-draining medicine group did not differ (P>0.05).</p><p><b>CONCLUSIONS</b>Blood-activating Chinese medicinal compounds and water-draining Chinese medicinal compounds can alleviate inflammation of peripheral tissue and cerebral edema. However, the blood-activating Chinese medicinal compounds were more effective than the water-draining Chinese medicinal compounds. The possible effective mechanism may be by means of inhibiting the activation of NF-κ B so as to suppress the transcription of target genes including gene expression of TNF-α.</p>

Objective To observe the efficacy of oral short-acting contraceptives after abortion surgery. Methods A to-tal of 200 cases who were voluntarily requested termination of pregnancy in our hospital were randomly divided into the observation group (100 cases) and the control group (100 cases). Antibiotics and Motherwort particles were given to the control group. Marvelon, antibiotics and Motherwort particles were given to the observation group after abortion. Thera-peutic effect of two groups was observed and compared. Results The observation group postoperative recovery was sig-nificantly better than the control group, the difference was statistically significant (P<0.05). The incidence of adverse reaction was significantly lower than that of the control group, the difference was statistically significant(P<0.05). Con-clusion Oral short-acting contraceptives after abortion surgery not only can promote postoperative recovery, reduce ad-verse reaction, beneficial to the women's physical and mental health.

Objective To study the factors that associated with the mortality of overdose on methadone maintenance treatment (MMT) among HIV-positive patients.Methods A 1 ∶ 1 matched case-control design was used to identify the relationship between factors related to demography,drug use,characteristics of treatment and the mortality of overdose.110 HIV-positive patients who died of drug overdose from March 2004 to September 2012 were defined as cases.Controls were another 110 patients who were still alive and paired with the cases,according to the same gender,similar date of MMT initiation and from the same clinics.Results Multivariate conditional logistic regression analyses indicated that risk factors as sharing needles before enrolled in the MMT program (OR=5.19,95% CI:1.39-19.33),HIV infection because of injecting drug-use (OR=3.08,95% CI:1.16-8.21),and off from the treatment before the end point of the program (OR=2.54,95%CI:1.23-5.23) were associated with mortality caused by overdose.Higher adherence (OR=0.31,95%CI:0.10-0.95) appeared to be associated with lower mortality when compared with the control group.Conclusion In order to reduce the mortality rate,comprehensive intervention could be introduced to improve the compliance of retention on MMT among patients.Intervention efforts should be focused on those patients who shared needle / syringes.
