OBJECTIVETo realize quadratic formula optimization of Renshen Jianxin Capsule (RJC) by screening Chinese herbs with major anti-myocardial ischemia effect in RJC and optimize their optimal dosages.

METHODSBy following "uniform design-pharmacodynamic experiment-mathematical modeling-formula optimization", authors employed U10(10(8)) uniform design in the experiment. Eight Chinese herbs contained in RJC were taken as observatory factors. Electrocardiograph (ECG) changes of myocardial ischemia induced by isoproterenol were taken as pharmacodynamic indices. The mathematical model between herbal factors and pharmacodynamic indices was established using stepwise regression analysis to screen Chinese herbs with major anti-myocardial ischemia effect. Their optimal dosages were optimized using the grid algorithm.

RESULTSThe regression equation was y =1. 7889 -0. 3247 Ginseng xSalvia Miltiorrhiza -0. 0663 Astragalus membranaceus xOriental Waterplantain tuber. Forecasting factors included were Ginseng, Salvia Miltiorrhiza, Astragalus membranaceus, and Oriental Waterplantain tuber. The optimal formula dosage calculated by the grid algorithm was Ginseng 1. 62 g, Astragalus membranaceus 4. 62 g, Salvia Miltiorrhiza 2. 43 g, and Oriental Waterplantain tuber 1. 66 g.

CONCLUSIONUniform design combined with stepwise regression analysis and grid algorithm were able to realize quadratic formula optimization of RJC.

OBJECTIVETo evaluate the relationship between PAR1 (Protease-Activated Receptor 1) expression and the clinicopathologic features and to investigate the prognostic value of PAR1 expression in hepatocellular carcinoma (HCC) in early stage after curative resection.

METHODSReal-time PCR was used to detect PAR1 expression in 41 pairs of tumors and matched peritumoral samples of HCC in early stage. Prognostic value of PAR1 mRNA expression was evaluated. Meanwhile, another 49 tissue paraffin slices of HCC were tested using immunohistochemistry (Envision) and the prognostic value of PAR1 expression and other clinicopathologic factors were evaluated.

RESULTSPeritumoral PAR1 mRNA expression was significantly increased in HCCs from the patients with tumor recurrence as compared with those without recurrence (P < 0.05). Peritumoral PAR1 protein expression was related to tumor differentiation (P < 0.05). Kaplan-Meier analysis showed that Peritumoral PAR1 protein expression was associated with the overall survival (OS) (P < 0.05) of HCC patients and the time to recurrence (TTR) (P < 0.05). The 1, 3 and 5 -year overall survival time and the cumulative recurrence time in the high PAR1 protein expression group were significantly lower as compared to the low PAR1 expression group in the peritumoral liver tissue.

CONCLUSIONSPeritumoral PAR1 expression is closely associated with the prognosis of early stage HCC patients after curable surgery. PAR1 may be involved in thrombin-mediated invasion process and may be used as a prognostic marker for HCC.

OBJECTIVETo explore the growth characteristics of Curcuma longa, and provide basis for standardized cultivation.

METHODPlant samples were collected and investigated periodically.

RESULTAccording to the growth of different parts and the characteristics of dry substance accumulation of C. longa, the development of C. longa could be divided into five stages: emergence of seedlings, seedling, leaf, root tuber expansion, and dry substance accumulation of root tuber. In terms of number, leaf of C. longa increases gradually from one at first to eight at the final stage. Leaf size increases at a very low speed at the stage of seedling. However, leaves expands their sizes at a much higher speed at the stage of leaf. The dry substance in different parts accumulates increasingly with the development of C. longa dry substance mainly accumulates in leaves at the stage of leaf, and in rhizome at the stage of root tuber expansion. At the final stage, it mainly accumulates in root tuber.

CONCLUSIONCultivation technologies of C. longa and the relevant management methods could be established according to the growth of different parts of C. longa and the characteristics of dry substance accumulation in different stages.

OBJECTIVETo analyze tracheal intubation and respiratory treatment in the critical severe acute respiratory syndrome (SARS) patients.

METHODSReview and analyze tracheal intubation and respiratory treatment in critical SARS patients in intensive care unit (ICU).

RESULTSThree of thirteen patients had been intubated or received tracheotomy before they entered into ICU, the other patients received treatment of nasal cannula or oxygen mask. With the development of the disease, two patients had been intubated because of respiratory failure or tracheotomy. Tracheal intubation was twice made in two patients in order to replace tracheal tubes.

CONCLUSIONSThe patient should be intubated or received tracheotomy if non-invasive respiratory support has no effect. Standard protection could protect medical staff from infection under tracheal intubation.

OBJECTIVES: To compare the effect of different frequency of acupoint thread-embedding on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention. METHODS: A total of 126 subjects with overweight/obesity of spleen deficiency and dampness retention were randomized into a 2-week group(63 cases, 13 cases dropped out)and a 3-week group(63 cases, 11 cases dropped out, 1 case was eliminated). The two groups were treated with acupoint thread-embedding once every 2 weeks and once every 3 weeks respectively, Zhongwan(CV 12), Shuifen(CV 9), Qihai(CV 6), Guanyuan(CV 4) and bilateral Zhangmen(LR 13), Tianshu(ST 25), Liangmen(ST 21), Daheng(SP 15), Fujie(SP 14), Pishu(BL 20), Yinlingquan(SP 9)were selected. Four times were required in the two groups. Before and after treatment, follow-up after 2 months of treatment completion, the body mass index(BMI), body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, fat percentage(F%), skin fold thickness were observed in the two groups. RESULTS: After treatment and in follow-up, the BMI, body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, F%, skin fold thickness in the two groups were decreased compared with those before treatment (P<0.001, P<0.01), the changes of BMI, body weight, obesity degree, F%, skin fold thickness in the 2-week group were larger than those in the 3-week group(P<0.05, P<0.01, P<0.001). CONCLUSIONS The effect of acupoint thread-embedding once every 2 weeks on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention is superior to that once every 3 weeks.

OBJECTIVETo investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus (GDM).

METHODSA total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation (WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity.

RESULTSAge, pre-pregnant body weight (BW), and body mass index (BMI) were associated with increased risk of GDM. Fat mass (FM), fat mass percentage (FMP), extracellular water (ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass (FFM), muscular mass (MM), and intracellular water (ICW) were associated with a decreased risk of GDM.

CONCLUSIONMaternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity.

OBJECTIVE: To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients. METHODS: By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup. RESULTS: Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens. CONCLUSIONS There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.
