Viral myocarditis (VMC) is normally caused by myocarditis virus infection. Currently, the Western medicine treatment is mainly about symptomatic supportive treatment, while TCM has remarkable efficacy for this disease. This article started from the 4 common mechanisms of VMC, and elaborated the effects of individual and compound preparation, such as antiviral, regulating immune, anti free redical, antioxidation, improving myocardial metabolism, protecting myocardial cells, with a purpose to provide experimental references for TCM application in clinic.

Wistar rats with different levels of iodine nutrition were killed after 3,6 and 12 months of experiments.Serum thyroid hormones were assayed with RIA.The activity of typeⅠdeiodinase(DⅠ)and typeⅡdeiodinase(DⅡ)was measured based on the release of radioiodide from the ~(125)Ⅰ-labeled substrate.The result showed that hypothyroidism reflected by decreased T_4 happened during the initial phase of iodine deficiency.The activity of DⅠand DⅡin rats was raised significantly in iodine deficiency groups.An excess of iodine inhibited DⅠactivity resulting in decreased serum TT_3 and FT_3.However,DⅡactivity increased in rats with iodine excess, attributing to the inactivation of T_3 and T_4 to the substrate of DⅡenzyme.

Protein palmitoylation, one of post-translation modifications, refers to the addition of saturated 16-carbon palmitic acid to cysteine residues via the thioester bond. It plays key roles in various functional activities, such as the interaction, stability and location of proteins. Heat shock protein 90 (Hsp90), an important molecular chaperone, has been reported to be involved in sperm capacitation. However, it remains unclear whether protein palmitoylation exists in sperm and whether Hsp90 in sperm is palmitoylated under different physiological conditions. In this study, we examined whether the protein palmitoylation is present in mouse cauda epididymis sperm using acyl-biotin exchange method, predicted the potential palmitoylated sites of Hsp90 by the software CSS-Palm 4.0 and detected the palmitoylated Hsp90 in the mouse sperm from caput epididymis and cauda epididymis by immunoprecipitation. We found that some proteins, approximately 50, 65, 72, 85 and 130 kDa, were palmitoylated in mouse cauda epididymis sperm. Five sites in two Hsp90 isoforms were predicted to be palmitoylated. The results also showed that Hsp90 in mouse sperm was palmitoylated and its palmitoylation level was involved in different physiological conditions: the palmitoylation level of cauda epididymis sperm was higher than that of caput epididymis sperm; and the palmitoylation level after capacitation was much higher than that before capacitation. In conclusion, this study reveals that protein palmitoylation is present in mouse sperm and the palmitoylated Hsp90 is associated with different physiological conditions in sperm.

BACKGROUNDThe E-26 transformation-specific related gene (ERG) is frequently expressed in cytogenetically normal acute myeloid leukemia (CN-AML). Herein, we performed a meta-analysis to investigate the relationship between the prognostic significance of ERG expression and CN-AML.
METHODSA systematic review of PubMed database and other search engines were used to identify the studies between January 2005 and November 2016. A total of 667 CN-AML patients were collected from seven published studies. Of the 667 patients underwent intensive chemotherapy, 429 had low expression of ERG and 238 had high expression of ERG. Summary odds ratio (OR) and the 95% confidence interval (CI) for the ERG expression and CN-AML were calculated using fixed- or random-effects models. Heterogeneity was assessed using Chi-squared-based Q- statistic test and I2 statistics. All statistical analyses were performed using R.3.3.1 software packages (R Foundation for Statistical Computing, Vienna, Austria) and RevMan5.3 (Cochrane Collaboration, Copenhagen, Denmark).
RESULTSOverall, patients with high ERG expression had a worse relapse (OR = 2.5127, 95% CI: 1.5177-4.1601, P = 0.0003) and lower complete remission (OR = 0. 3495, 95% CI: 0.2418-0.5051, P< 0.0001). With regard to the known molecular markers, both internal tandem duplications of the fms-related tyrosine kinase 3 gene (OR = 3.8634, 95% CI: 1.8285-8.1626, P = 0.004) and brain and acute leukemia, cytoplasmic (OR = 3.1538, 95% CI: 2.0537-4.8432, P< 0.0001) were associated with the ERG expression. In addition, the results showed a statistical significance between French-American-British (FAB) classification subtype (minimally differentiated AML and AML without maturation, OR = 4.7902, 95% CI: 2.7772-8.2624, P< 0.0001; acute monocytic leukemia, OR = 0.2324, 95% CI: 0.0899-0.6006, P = 0.0026) and ERG expression.
CONCLUSIONHigh ERG expression might be used as a strong adverse prognostic factor in CN-AML.

OBJECTIVETo evaluate the efficacy and safety of Heyan Kuntai Capsule (, HYKT) and hormone therapy (HT) on perimenopausal syndromes (PMSs).
METHODSFrom 2005 to 2008, 390 women with PMSs were recruited from 4 clinic centers. The inclusion criteria included ages 40 to 60 years, estradiol (E2) below 30 ng/L, and follicle stimulating hormone (FSH) above 40 IU/L, etc. The patients were randomly assigned to HYKT group or HT group by random number table method, administrated HYKT or conjugated estrogen with/without medroxyprogesterone acetate tablets for 12 months. During treatment, the patients were interviewed quarterly, Kupperman Menopausal Index (KMI) scores, hot flush scores, insomnia scores, Menopause-Specific Quality of Life (MENQOL) scores and adverse effects were used for evaluating drug efficacy and safety respectively. The last interview was made at the end of 12-month treatment RESULTS: After treatment, KMI scores of HYKT group and HT group were both significantly decreased compared with baseline (P <0.01) and there was no significant difference between groups (P >0.05), except that KMI of HYKT group was higher after 3-month treatment (P <0.05). After treatment, hot flush and insomnia scores were both improved significantly in two groups (P <0.01); and HT had a better performance than HYKT in improving hot flush (P <0.05). MENQOL were significantly improved in both groups after treatment (P <0.01); but there was no significant difference between two groups (P >0.05). The incidence of adverse event in the HYKT group was much lower than that in the HT group (P <0.01).
CONCLUSIONSHYKT could effectively relieve PMSs and improve patients quality of life without severe adverse reactions. Although HYKT exerted curative effects more slowly than hormone, it possessed better safety profile than hormone.

OBJECTIVE:
To explore clinical effect of arthroscopy-assisted rotator cuff tendon transfer in treating irreparable rotator cuff tears (IRCT).
METHODS:
From May 2015 to May 2018, 23 patients with unrepairable rotator cuff tears were treated with arthroscopy-assisted rotator cuff tendon transfer, and 21 patients were followed up finally, including 8 males and 13 females, aged from 48 to 82 years old with an average of(64.3±9.1) years old;the courses of disease ranged from 6 to 36 months with an average of (14.0±6.4) months. American Rotator and Elbow Surgeons Score(ASES) and Constant-Murley score were used to evaluate clinical efficacy before surgery and at the latest follow-up.
RESULTS:
All 21 patients were followed up for 36 to 54 months with an average of (39.4±4.4) months. Axillary incision of 1 patient was redness, swelling and exudation after surgery, which healed after 3 weeks of dressing change, and exudate culture was negative. At the latest follow-up, MRI showed partial tearing of the metastatic tendon in 2 patients, but pain and movement of the affected shoulder were still better than before surgery. ASES increased from preoperative (41.0±9.6) scores to the latest follow-up (75.6±14.0) scores, and had statistical difference (t=10.50, P<0.01). Constant-Murley score increased from (49.8±7.1) scores before operation to (67.5±11.6) scores at the latest follow-up (t=11.27, P<0.01).
CONCLUSION
Arthroscopic assisted latissimus dorsalis tendon transposition restores physiological and anatomical structure of glenohumeral joint by reconstructing balance of horizontal and vertical couples of shoulder joint, thus achieving the stability of the shoulder joint, relieving shoulder pain and improving shoulder joint function.
