Cardiovascular diseases (CVDs) and malignant tumors are the main causes of death worldwide. The etiology study of CVDs and malignant tumors has found a series of widely recognized risk factors. Medical practice and medical theory usually focus on one of the diseases, but more and more evidence reveals that malignant tumors usually involve the cardiovascular system, thus leading to thromboembolism, heart failure, etc. Anti-cancer treatment proves to induce CVDs, while CVDs seem to increase the risk of malignant tumors. This situation requires researchers to conduct further combined crossover study on both CVDs and malignant tumors. In this review, we discuss the potential common risk factors of cardiovascular diseases and malignant tumors, the pathological and physical mechanism of the two kinds of diseases, the cardiac toxicity induced by tumor therapy and the impact of cardiovascular drugs on cancer from the perspective of cardio-oncology, and in the endput forward the prospect of prevention and treatment.

The aim of this paper was to observe the combination therapy with total triterpenoids of Chaenomeles speciosa and omeprazole on indomethacin-induced gastric ulcer in rats, and explore its possible mechanism. Rats were randomly divided into normal group, model group, omeprazole monotherapy(3.6 mg·kg~(-1)) group, total triterpenoids of C. speciosa monotherapy(100 mg·kg~(-1)) group, total triterpenoids of C. speciosa and omeprazole combination therapy(100 mg·kg~(-1)+3.6 mg·kg~(-1)) group. Except for the normal group, the other groups were given indomethacin(20 mg·kg~(-1)) by oral once a day for 7 consecutive days. Then the treated groups were given corresponding drugs by gavage, once a day for 14 consecutive days. The next day after the last administration, half of the rats in each group were measured the gastric mucosal blood flow, gastric juice volume and serum TNF-α, IL-1β, IL-6, IL-4 and IL-10. After the remaining rats in each group were underwent pyloric ligation 4 hours after the last administration, the gastric endocrine volume, pH value and total acidity of gastric secretion were measured, then histological analysis was performed, MPO activity, cAMP content and histomorphological analysis were conducted. Real-time PCR was applied to detect the mRNA expressions of gastric tissue TNF-α,IL-1β, IL-6, IL-4, IL-10, VEGFA, A_(2A)R; the protein expressions of VEGFA, A_(2A)R, PKA, p-PKA, CREB, p-CREB, EGF, EGFR, p-EGFR, MUC6, TFF2 in gastric tissue were detected by Western blot. The results indicated that total triterpenoids of C. speciosa and omeprazole combination therapy might significantly increase gastric mucosal blood flow, gastric mucus volume, reduce gastric endocrine volume, secretion acidity and mucosal damage, decrease the levels of TNF-α,IL-1β and IL-6, increase the levels of IL-4 and IL-10 in blood and gastric tissue, inhibit the activity of MPO, increase the content of cAMP in gastric tissue, up-regulate the mRNA expressions of VEGFA, A_(2A)R and protein expressions of VEGFA, A_(2A)R, PKA, p-PKA, CREB, p-CREB, EGF, EGFR, p-EGFR, MUC6, TFF2 in gastric tissue, elevate p-PKA/PKA, p-CREB/CREB and p-EFGR/EFGR. Moreover, the combination therapy with total triterpenoids of C. speciosa and omeprazole was more obvious than those of two monotherapies. These aforementioned findings suggested that the combination therapy with total triterpenoids of C. speciosa and omeprazole on indomethacin-induced gastric ulcer have significant therapeutic effect on indomethacin induced gastric ulcer in rats, its mechanism might be related to regulating A_(2A)R/AKT/CREB, A_(2A)R/VEGFA, EGF/EGFR and MUC6/TFF2 signaling pathways, inhibiting pro-inflammatory factors, increasing gastric mucosal blood flow, up-regulating mucosal cell proliferation factors and promoting mucosal protective factors.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary. RESULTS: A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001). CONCLUSIONS The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.

MSC transplantation has been explored as a new clinical approach to stem cell-based therapies for bone diseases in regenerative medicine due to their osteogenic capability. However, only a small population of implanted MSC could successfully reach the injured areas. Therefore, enhancing MSC migration could be a beneficial strategy to improve the therapeutic potential of cell transplantation. Catharmus tinctorius volatile oil (CTVO) was found to facilitate MSC migration. Further exploration of the underlying molecular mechanism participating in the pro-migratory ability may provide a novel strategy to improve MSC transplantation efficacy. This study indicated that CTVO promotes MSC migration through enhancing ROCK2 mRNA and protein expressions. MSC migration induced by CTVO was blunted by ROCK2 inhibitor, which also decreased myosin light chain (MLC) phosphorylation. Meanwhile, the siRNA for ROCK2 inhibited the effect of CTVO on MSC migration ability and attenuated MLC phosphorylation, suggesting that CTVO may promote BMSC migration via the ROCK2/MLC signaling. Taken together, this study indicates that C. tinctorius volatile oil could enhance MSC migration via ROCK2/MLC signaling in vitro. C. tinctorius volatile oil-targeted therapy could be a beneficial strategy to improve the therapeutic potential of cell transplantation for bone diseases in regenerative medicine.

To study the antidepressant effect of Shugan Hewei Tang on chronic stress depression model rats, and select the effective substance fractions. Several male SD rats were randomly divided into 17 groups: blank control group, model group, positive control group(fluoxetine), Shugan Hewei Tang high and low dose groups, 6 high and low dose groups of different substance fractions. After modeling for 3 weeks and administration for 1 week, the effective substance fractions were selected according to the body mass and behavioral performance of SD rats in each group; several neurotransmitters in hippocampus of rats were determined by LC-MS/MS method, including norepinephrine(NE), serotonin(5-HT), 5-indoleacetic acid(5-HIAA), r-aminobutyric acid(GABA), and glutamic acid(Glu). Behavioral results after modeling showed that as compared with the blank group, the body mass growth of the model group was significantly reduced(P<0.01); the sugar water consumption was reduced(P<0.01); the distance between the open field and the number of crossing the central area were also significantly reduced(P<0.01, P<0.01); the resting time was increased significantly(P<0.01); and the forced swimming time was significantly prolonged(P<0.01), indicating that the depression model was effective. After intragastric administration, as compared with the model group, the above detection indicators of volatile oils, total polysaccharides and terpenoid in Fluoxetine, Shugan Hewei Tang groups were all changed(P<0.05 or P<0.01). The levels of NE, 5-HT and GABA in the hippocampus of the model group were significantly lower than those in the blank group(P<0.01), and the levels of 5-HIAA and Glu were significantly increased(P<0.01). As compared with the model group, neurotransmitters of the treatment groups were changed obviously or significantly(P<0.05 or P<0.01). Shugan Hewei Tang showed obvious anti-depressant effects, and the volatile oils, total polysaccharides and terpenoids acted as the main active substances. The mechanism of anti-depression may be related to its regulation of various neurotransmitter levels in the hippocampus.

Shenfutang is a famous prescription used in clinic. It has been used for more than one thousand years, and currently is still widely used in clinic, with a significant effect. Shenfutang was first recorded in the Shengji Collection. It consists of two herbs, namely Ginseng Radix Et Rhizoma and Aconiti Lateralis Radix Praeparata. It can be used to mainly treat syncope and collapse due to sudden collapse of Yang Qi, and the symptoms include disfigurement of the extremities, cold sweats, cold limbs, umbilical and abdominal pain, weak breathing, and slight desire. Ginseng supports healthy Qi, and comforts five organs. Aconitum is good at activating twelve meridians and collaterals. With the effect of returning the yang to rescue the enemy, aconitum can also support yang. Different ratios of ginseng and aconitum are combined for reinforcing Yang of heart, kidney and spleen, so as to treat various syndromes. However, the occurrence and development of diseases are complicated and changeable. Different ratios of Shenfutang may increase the efficacy due to the synergistic effect, or weaken or even lose the original efficacy due to mutual antagonism. Different ratios of ginseng and aconitum can be used for different diseases, such as cardiovascular disease, various types of inflammation, respiratory diseases. In the existing literatures on Shenfutang, there is a lack of systematic summarization for how to adjust the ratios. This paper introduces the effect and mechanism of the combination, and summarizes different ratios of the two herbal ingredients, so as to provide certain reference for the clinical application.

Objective: To evaluate the effect of manual decocting and machine decocting on the chemical constituents in Bazhentang based on non-targeted metabolomics, and to find the differential chemical constituents of these two decocting methods. Method: Bazhentang was boiled by standardized manual decocting and machine decocting methods,respectively. Orthogonal partial least square-discriminate analysis(OPLS-DA) and other multivariate statistical methods, combined with variable importance in the projection(VIP) value and t-test, were employed to analyze the effect of two decocting methods on the chemical constituents in Bazhentang. The differential chemical constituents were analyzed by UPLC-LTQ-Orbitrap MS under positive and negative ion modes,mobile phase was acetonitrile-0.1%formic acid aqueous solution for gradient elution,the scanning range was m/z 50-1 500. Result: Under the positive and negative ion modes of high-resolution mass spectrometry, a total of 87 differential components were found,40 of them were identified according to the mass spectrometry data and literature reports, including senkyunolide A, glycyrrhizin, ferulic acid, etc. Conclusion: Based on the analysis of color and chemical compositions of Bazhentang, there are obvious differences between the standardized manual decocting and machine decocting. If the advantages of these two methods are combined,a standardized decoction process can be established on the basis of maintaining the advantages of manual decocting, the effectiveness of traditional Chinese medicine decoction will be maximized and it will be convenient for patients to take it.
