To analyze the compatibility regularity of compound traditional Chinese medicine (TCM) patents for treating dyslipidemia, and provide basis for the clinical development and research of new TCM for treating dyslipidemia. Totally 243 compound traditional Chinese medicine patents for treating dyslipidemia were collected from the national patent database from September 1985 to March 2014 and analyzed by using drug frequency, association rules, complex network and entropy method of Traditional Chinese Medicine Inheritance System (V1.1). The commonest single medicine in the treatment of dyslipidemia is Crataegi Fructus 109 (44.86%). The commonest pair medicine is Crataegi Fructus-Salviae Miltiorrhizae Radix et Rhizoma 53 (21.81%). The commonest corner drug is Crataegi Fructus-Cassiae Semen-Polygoni Multiflori Radix 25 (10.29%). The common prescriptions on basis of association rules are Prunellae Spica-->Salviae Miltiorrhizae Radix et Rhizoma (0.833), Rhei Radix et Rhizoma, Alismatis Rhizoma-->Polygoni Multiflori Radix (1.00), Salviae Miltiorrhizae Radix et Rhizoma, Cassiae Semen, Alismatis Rhizoma-->Polygoni Multiflori Radix (0.929). The core drugs based on complex networks are Salviae Miltiorrhizae Radix et Rhizoma and Crataegi Fructus. The new prescriptions extracted by entropy method are Atractylodis Macrocephalae Rhizoma-Glycyrrhizae Radix et Rhizoma-Platycladi Semen-Stephaniae Tetrandrae Radix; Citri Reticulatae Pericarpium-Poria-Coicis Semen-Pinelliae Rhizoma. This study shows the regularity in the compatibility of compound TCM patents treating dyslipidemia, suggesting that future studies on new traditional Chinese medicines treating dyslipidemia should focus on the following six aspects: (1) Single medicine should be preferred: e. g. Crataegi Fructus; (2) Pair medicines should be preferred: e. g. Crataegi Fructus-Salviae Miltiorrhizae Radix et Rhizoma; (3) Corner drugs should be preferred: e. g. Crataegi Fructus, Cassiae Semen, Polygoni Multiflori Radix; (4) The compatibility among drugs shall be given attention, and highly correlated drugs should be preferred: e. g. Prunellae Spica, Salviae Miltiorrhizae Radix et Rhizoma; Rhei Radix et Rhizoma, Alismatis Rhizoma, Polygoni Multiflori Radix; Salviae Miltiorrhizae Radix et Rhizoma, Cassiae Semen, Alismatis Rhizoma, Polygoni Multiflori Radix; (5) Core drugs should be dominant and compatible, e. g. in the digestion catharsis method, the core drugs is Crataegi Fructus and compatible with Salviae Miltiorrhizae Radix et Rhizoma; (6) Application of new prescriptions: Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Platycladi Semen, Stephaniae Tetrandrae Radix; Citri Reticulatae Pericarpium, Poria, Coicis Semen, Pinelliae Rhizoma.

The roles of voltage-dependent K(+) channels during activation and damage in alveolar macrophages (AMs) exposed to different silica particles were examined. Rat AMs were collected by means of bronchoalveolar lavage, and were adjusted to 5x10(5)/mL. After AMs were exposed to different concentrations (0, 25, 50, 100, 200 mug/mL) of quartz particles and 100 mug/mL amorphous silica particles for 24 h, the voltage-depended K(+) current in AMs was measured by using patch clamp technique. Meanwhile the leakage of lactate dehydrogenase (LDH) and the viability of AMs were detected respectively. Patch clamp studies demonstrated that AMs possessed outward delayed and inward rectifying K(+) current. Exposure to quartz particles increased the outward delayed K(+) current but it had no effect on inward rectifier K(+) current in AMs. Neither of the two K(+) channels in AMs was affected by amorphous silica particles. Cytotoxicity test showed that both silica particles could damage AM membrane and result in significant leakage of LDH (P<0.05). MTT studies, however, showed that only quartz particles reduced viability of AMs (P<0.05). It is concluded that quartz particles can activate the outward delayed K(+) channel in AMs, which may act as an activating signal in AMs to initiate an inflammatory response during damage and necrosis in AMs induced by exposure to quartz particle. K(+) channels do not contribute to the membrane damage of AMs.

OBJECTIVETo evaluate the application of shear wave elastography (SWE) combined with transition zone biopsy in the detection of prostate cancer (PCa).

METHODSA total of 489 patients with suspected PCa underwent transrectal ultrasonography (TRUS) and SWE-guided prostatic biopsy. We evaluated the role of SWE combined with transition zone biopsy in promoting the detection rate in comparison with the results of biopsy pathology.

RESULTSThe pathological results confirmed 221 malignant and 268 benign cases. Based on systematic biopsy, SWE combined with transition zone biopsy achieved a detection rate of 45. 19% , significantly higher than that of systematic biopsy alone (33.13%) (P < 0.05). The diagnostic sensitivity, specificity, and accuracy of SWE were significantly better than those of TRUS (P < 0.05). The mean elasticity (Emean) of SWE was remarkably higher for malignant than for benign lesions ([40.1 ± 9.5] vs [21.6 ± 8.3] kPa, P < 0.05). With 28.5 kPa as the threshold of the Emean value, the area under the ROC curve was 0. 899, and the diagnostic sensitivity and specificity were 88.71% and 86.23%, respectively.

CONCLUSIONSWE combined with transition zone biopsy could significantly improve the detection rate of prostate cancer.

Objective To investigate effects of penehyclidine hydrochloride (PHC)protects a-gainst acute lung injury (ALI)in heart valve replacement patients with cardiopulmonary bypass (CPB).Methods Thirty rheumatic heart disease patients,eighteen males and twelve females with NYHA Ⅱ or Ⅲ,with cardiac valve replacement undergoing CPB were enrolled in the study.All pa-tients were randomly divided into group P and group C (fifteen in each group).Patients in group P re-ceived an intravenous injection of 0.03 mg/kg PHC before anesthesia induction and those in group C received the same volume of normal saline.Blood samples were collected to monitor the concentrations of IL-6,TNF-αand NF-κB at the following time points:before anesthesia induction (T0 ),the end of the operation (T1 ),6 hours (T2 ),12 hours (T3 )and 24 hours(T4 )postoperatively,arterial blood gas analyses were detected and oxygenation index (OI)was calculated at the time of T0 ,T1 and T4 , as well as lung dynamic compliance of patients adopt at the time of soon after anesthesia induction and the end of the operation.The outcomes included duration of intubation (DOI),length of intensive care unit stay (LOI)and length of hospital stay after the surgery (LOH).Results The DOI,LOI and LOH in group P were shorter than those in group C,but there was no statistical significance between groups.The plasma levels of IL-6,TNF-α and NF-κB were higher at T1-T4 than T0 in both groups (P <0.05),and those in group P were statistically lower than group C at T1-T4 (P <0.05).The val-ues of OI at T0 and T1 were obviously lower than T4 in both groups (P <0.05),and that in group P was slightly higher than group C at T4 but without statistical significance.The lung dynamic compli-ance of patients in group P at the end of operation was obviously higher than that in group C (P <0.05).Conclusion PHC inhibits systemic inflammatory response,improves lung compliance,amel-iorates tissue oxygen supply and encourages postoperative rehabilitation in valve heart replacement pa-tients with CPB,and its mechanisms is relevant to the regulation of NF-κB signal way on the produc-tion of such proinflammatory cytokines as IL-6 and TNF-α.

In silkworm moth the colleterial gland markedly enlarged due to the secretion and accumulation of glue like substances before adult emergence. However, the Ng mutant female moth only secreted little glue-like substance and laid loose eggs naturally. In the present experiment, it was extracted the proteins of secretory part of the variety E981 and its Ng mutant line and analyzed by two-dimensional electrophoresis. More than 700 protein spots were resolved both in two samples and most of the proteins were distributed in the area from 30 kD to 70 kD and pH 4 - 8. Through the comparison and analysis, it was found that 4 proteins were only expressed in E981 and 2 proteins were only expressed in Ng mutant. Furthermore, there are about 29 proteins were expressed higher in 981 and about 15 proteins expressed volume were higher in Ng mutant. These differential proteins may be have some relations with the Ng mutant form and directly lead to the Ng mutant can't secret the glue-like substance.

To study the effect of Tibetan medicine Zuotai on the activity, protein and mRNA expression of CYP1A2 and NAT2, three different doses (1.2, 3.8 and 12 mg x kg(-1)) of Zuotai were administrated orally to rats once a day or once daily for twelve days, separately. Rats were administrated orally caffeine (CF) on the second day after Zuotai administration, and the urine concentration of CF metabolite 5-acetylamino-6-formylamino-3-methyl-uracil (AFMU), 1-methyluric acid (1U), 1-methylxanthine (1X), 1, 7-dimethylxanthine (17U) at 5 h after study drug administration was determined by RP-HPLC. The activity of CYP1A2 and NAT2 was evaluated by the ratio of metabolites (AFMU+1X+1U)/17U and the ratio of AFMU/(AFMU+1X+1U), respectively. The protein and mRNA expression of CYP1A2 and NAT2 were determined by ELISA and RT-PCR method, respectively. After single administration of Zuotai 3.8 mg x kg(-1) and repeated administration of Zuotai 3.8 and 12 mg x kg(-1), the activity of CYP1A2 and NAT2 decreased significantly compared with control group and there was no significant difference between other dose group and control group. The protein expression of CYP1A2 was significant lower than that in control group after repeated administration of Zuotai 12 mg x kg(-1), and the mRNA expression of CYP1A2 decreased significantly compared with that of control group after single administration of Zuotai 3.8 mg x kg(-1) and repeated admistration of Zuotai 12 mg x kg(-1), separately. The protein expression of NAT2 decreased significantly compared with that of control group after single and repeated administration of Zuotai 3.8 mg x kg(-1), respectively, and the mRNA expression of CYP1A2 decreased significantly compared with control group after single administration of Zuotai 3.8 mg x kg(-1). This study found that Tibetan medicine Zuotai had significant effect on the activity, protein and mRNA expression of CYP1A2 and NAT2.

Objective: To analyze the correlation between physical activity and physical fitness index of children and adolescents in China, so as to provide reference for physical activity and physical fitness promtion of children and adolescents. Methods: In September 12,2018, 4 269 students were selected by cluster sampling in east, northwest, north, central, southwest and South China, the test of standing long jump, grip strength, 50 m running, improved seat forward bend, 30 s sit ups, 20 s cross repeatedly, 20 m round trip running was completed. Results: In comparing the physical fitness index of children and adolescents with different levels of physical activity, the PFI values of the middle and high intensity physical activity (MVPA) groups of boys aged 10-12 and 16-18 years old were (0.46±3.58) (0.75±3.0), the value of PFI of the MVPA group were (-0.69±3.64) (-0.61±2.87), the difference was statistically significant ( t =0.04, 0.57, P >0.05). There was no significant difference in the values of PFI between the four age groups of the girls ( P <0.05). In comparison of physical activity status of children and adolescents in different physical ability grades, the time of MPA, VPA and physical exercise in healthy physical ability group was higher than that in unhealthy physical ability group ( Z =-2.04, -4.93, -7.09, P <0.05). Linear regression analysis showed that there was a positive correlation between daily MVPA, physical exercise and physical fitness index ( P <0.05). Conclusion Moderate and high intensity physical activity, that is, physical exercise, is positively correlated with physical fitness index. Therefore, it is particularly important for children and adolescents to engage in sufficient moderate and vigorous intensity physical activities.

Objective: To understand the correlation between physical activity (PA) and socioeconomic status (SES) among Chinese children and adolescents, and to provide theoretical basis for physical activity promotion for Chinese children and adolescents. Methods: By using stratified random cluster sampling, a total of 4 269 children and adolescents aged 7 to 18 were selected from six cities in China from September to December 2018. Physical Activity Level Evaluation Questionnaire of Chinese Children and Adolescents Aged 7 to 18 was used to investigate PA and SES, and the height and weight were measured. Methods: In terms of different intensity of PA, the time spent on light intensity physical activity(LPA), moderate intensity physical activity(MPA), moderate to vigorous physical activity(MVPA)and total physical activity(TPA) in low SES group was 28.5(6.9,57.1) min/d, 46.2 (25.7,79.2) min/d, 61.4(34.3,101.9) min/d and 102.9(65.0,145.8)min/d respectively, which was higher than that in middle SES groups [ 21.4 (4.3,50.7), 37.1(18.6,65.7), 50.3(27.1,86.8), 85.7(49.3,127.1) min/d] and high SES groups [24.3( 5.0 ,54.3), 40.0(21.4,69.1), 54.3(32.9,91.4), 89.6(55.7,132.9) min/d]( P <0.01). In terms of different types of PA, the traffic PA [40.0(15.0,68.6) min/d] and entertainment PA[4.3(0,17.1)min/d] accounted the highest proportion in low SES group,while sports PA [36.4(20.7,60.7) min/d] accounted the highest proportion in high SES group( P <0.01).The compliance rates of MVPA in low, middle and high SES groups were 51.1%, 42.5% and 45.2%, respectively, and the differences were statistically significant ( χ 2= 22.02 , P <0.05). After controlling for confounding factors, the detection rate of MVPA in the low SES group was 1.24 times higher than that in the high SES group ( P <0.01). Conclusion The MVPA and TPA time of children and adolescents with middle SES group were the lowest. Physical activities spent on traffic and entertainment account highest in low SES group, while physical activities spent on sports account highest in high SES group.
