Analysis of Ticagrelor's Cardio-protective Effects on Patients with ST-segment Elevation Acute Coronary Syndrome Accompanied with Diabetes.

BACKGROUND: To analyze the cardio-protective effects of ticagrelor in patients with acute coronary syndrome with S-T segment elevation. METHODS: The sample was 200 patients who had been diagnosed with acute coronary syndrome accompanied by diabetes Mellitus type II. Only patients having ST segment elevation before the treatment were included. Then, the subjects were further randomly divided into an observation group and a control group. The control group of 100 patients received clopidogrel; the observation group of 100 patients of ticagrelor. The serous creatine kinase CK-MB, functional cardiac indexes of left ventricular end diastolic diameter (LVDD), cardiac troponin I, ventricular ejection fraction, and relevant major adverse cardiovascular events (MACE) were compared between the two groups. RESULTS: One month after a percutaneous coronary intervention (PCI) the observation group showed better results against angina, stent thrombosis, and all-cause mortality compared with those of the control subjects. Six months after treatment, both groups suffered adverse reactions. The number of patients who suffered adverse reactions in respiratory tract in the observation group was higher than in the control group. The inhibition of platelet aggregation IPA of ticagrelor was found to be significantly higher than clopidogrel, having a significant p value. CONCLUSION: Ticagrelor can effectively protect myocardial function for patients with ST-segment elevation acute coronary syndrome accompanied by diabetes and can reduce the incidence of adverse reactions..

Overexpression of apelin in Wharton' jelly mesenchymal stem cell reverses insulin resistance and promotes pancreatic ß cell proliferation in type 2 diabetic rats.

BACKGROUND: Apelin plays a key beneficial role in energy metabolism by increasing glucose uptake and insulin sensitivity; however, apelin has a short half-life because it is rapidly cleared from the circulation limiting its therapeutic benefit. The aim of this study is to create a new approach to treat type 2 diabetes by inducing prolonged expression of apelin in Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs). METHODS: A type 2 diabetic rat model was given a high-fat diet combined with low-dose streptozotocin (STZ) injection. The human WJ-MSCs were isolated and subsequently transduced with apelin-expressing lentiviral particles (WJMSCs-apelin), and expression was verified by flow cytometry, Western blot, ELISA, and RT-PCR analysis. Type 2 diabetic rats were infused with either WJMSCs-apelin (2 × 106 cells) or an equivalent dose of saline through the tail vein injection 7 days after STZ injection. The therapeutic effects of each infusion group were evaluated by monitoring plasma glucose levels and performing glucose tolerance tests (OGTTs), insulin tolerance tests (IPITTs), confocal microscopy, and immunocytochemical analysis for quantitating islet beta cells. Plasma inflammatory cytokines IL-6 and TNF-α and anti-inflammatory factors adiponectin were measured as well. RESULTS: Type 2 diabetic rats infused with WJ-MSCs-apelin significantly decreased levels of blood glucose (from 26.03 ± 2.83 to 15.85 ± 2.13 mmol/L on 7 days P < 0.001, and to 9.41 ± 2.05 on 14 days, P < 0.001). Infusion of WJMSCs-apelin not only improved significantly insulin sensitivity and glucose disposal, but also promoted endogenous pancreatic ß cell proliferation (9.6-fold increase compared to the control group). Furthermore, infusion of the WJMSCs-apelin consistently increased insulin and C-peptide levels in the plasma, and the above effects persisted up to 42 days. The inflammatory cytokines IL-6 and TNF-α were significantly decreased, whereas anti-inflammatory factor adiponectin was significantly increased after WJ-MSC-apelin infusion. CONCLUSION: In this study, we report a novel approach to treat type 2 diabetic rats that combines apelin gene therapy with WJ-MSC cell therapy, which could provide a promising therapeutic option for management of type 2 diabetes clinically.

Efficacy of early treatment on 52 patients with preneoplastic hepatitis B virus-associated hepatocellular carcinoma by compound Phyllanthus Urinaria L.

OBJECTIVE: To observe the change in the number of antibodies of preneoplastic hepatocellular carcinoma (HCC) using early treatment by Compound Phyllanthus Urinaria L. (CPUL) on patients with preneoplastic hepatitis B virus (HBV)-associated HCC. METHODS: A total of 102 cirrhosis patients with regenerative or dysplastic nodules whose sera were tested positive for at least one of these six proteins (five up-regulated genes URG4, URG7, URG11, URG12 and URG19, and one down-regulated gene DRG2) were assigned randomly to two groups using continual random codes by SPSS software. Fifty-two patients were in the treatment group and 50 patients were in the control group. CPUL was used in the treatment group for 3 years, while the control group did not receive any treatment. The changes in HBV-DNA level, number of antibodies, and hepatocarcinogenesis occurred were observed. Patients who did not develop HCC were followed up for another 2 years. RESULTS: HBV-DNA levels decreased ⩾2log in 22.2% (10/45) of patients in the treatment group in contrast to only 5.0% (2/40) of patients in the control group (P=0.0228). The number of antibodies that were tested positive in the treatment group (1.08±1.01) was significantly lower compared with the control group (2.11±1.12) after 24 months of drug treatment (P<0.01). Both the positive rates of anti-URG11 (33/52) and anti-URG19 (31/52) were over 60% at baseline in the two groups, and were decreased to 48.1% (25/52) and 46.2% (24/52) respectively at 36 months of drug treatment, while the rates increased to 68.0% (34/50) and 66.0% (33/50) respectively (P=0.0417, P=0.0436) in the control group. The positive rate of anti-DRG2 was increased to 55.8% (29/52) at 36 months of drug treatment, while in the control group was decreased to 36.0% (18/50, P=0.0452). Among the 102 patients who developed HCC, 2 were in the treatment group and 9 were in the control group, meaning that a significant difference between the two groups (P=0.0212). In 11 patients who developed HCC, anti-URG11 and anti-URG19 were always positive, while anti-DRG2 was negative. Patients newly developing HCC were 6 (20.0%) in the control group, and only one (2.5%) in the treatment group (P=0.0441) during 2-year follow-up after the end of the treatment. CONCLUSIONS: Anti-URG11, anti-URG19 and anti-DRG2 could be used as early markers in the prediction of the therapeutic efficacy of CPUL in treating preneoplastic HCC. CPUL is useful in preventing or delaying the development of HBV-associated cirrhosis to HCC.

Zinc sulfate therapy of vocal process granuloma.

Vocal process granuloma is a benign lesion that occurs on the arytenoid cartilage. It tends to recur locally, and there is a great diversity of methods to treat it. Here, we reviewed the effects of zinc sulfate therapy program in 16 patients with vocal process granulomas. Eleven patients had a history of trauma or laryngeal intubation and five patients had unknown origin. Eleven had recurrence after one to three failed surgeries, and the others had no prior treatment. Symptoms included hoarseness, sore throat, lump sensation in the throat and cough that apparently improved. The granulomas did not recur for at least 1 year. No complications occurred. For vocal process granuloma, zinc sulfate therapy is good either as an initial or compensatory treatment.

Efficacy of ursodeoxycholic acid combined with Tongdan Decoction () on immunological indices and histopathological changes in primary biliary cirrhosis patients.

OBJECTIVE: To observe the efficacy of ursodeoxycholic acid (UDCA) combined with Tongdan: Decoction () on immunological indices and histopathological changes in patients with primary biliary cirrhosis (PBC) of IIor III histological stage. METHODS: Sixty PBC patients were assigned randomly and equally: to the control group treated with UDCA alone and the treatment group treated with UDCA combined with Tongdan Decoction. The immunological indices and histopathological changes were detected before and after 24-week treatment, and the follow-up lasted for 1-3 years. RESULTS: After 24-week treatment, CD4(+)CD28(-) in the peripheral blood was lowered and CD4(+)CD25(+) was increased in both groups, and better effect was shown in the treatment group (P<0.01). The levels of IgM, IgG, and IgA decreased markedly after 96-week treatment in the treatment group (P< 0.05, P< 0.01), while in the control group, only the latter two showed significant decrease after 148 week (all P<0.05). At the end of the 3-year follow-up, the medians of histopathological

[Combination of genioglossus advancement by non-trephine technic with uvulopalatopharyngoplasty for treatment of obstructive sleep apnea-hypopnea syndrome].

OBJECTIVE: To evaluate the efficacy and reliability of genioglossus advancement and hyoid suspension with non-trephine technic (GAHM) and uvulopalatopharyngoplasty (UPPP) for surgical obstructive sleep apnea-hypopnea syndrome treatment. METHODS: Twenty-six patients (4 female and 22 male) were classified as moderate and severe cases in terms of apnea hypopnea index (AHI) and Friedman classification in the present study. All cases patients underwent genioglossus advancement and hyoid suspension with non-trephine technic Uvulopalatopharyngoplasty UPPP. Pre- and postoperative polysomnography and Epworth sleepiness scale were performed to assess the therapeutic outcomes. RESULTS: The whole operation time ranged from 120-180 minutes. The average amount of bleeding in genioglossus advancement was about 50-100 ml. There were no severe complications during and after the operation. All the cases were followed up to one year. After surgery, AHI was decreased in both group cases, (42.9 +/- 6.6 vs 16.2 +/- 5.7) in the severe group, and 21.3 +/- 4.4 vs 11.3 +/- 5.2 (x(-) +/- s) in the moderate group. With success defined as AHI decreased by more than 50 per cent after surgery, the total success rate in moderate and severe group was 83.3% and 91.7%, respectively (P < 0.01). Furthermore, the success rate of the moderate group was higher than those of the severe group (P < 0.01). CONCLUSION: GAHM combined with UPPP may be beneficial for the moderate and severe OSAHS patients with oropharyngeal and hypopharyngeal obstruction.

[Endonasal anatomy of lacrimal sac and its clinical significance in dacryocystorhinostomy].

OBJECTIVE: To explore the intranasal surface localization of the lacrimal sac in endoscopic dacryocystorhinostomy. METHODS: Fifteen adult cadavers (30 sides) were studied, the data of projection position of the lacrimal sac on the lateral wall of nasal cavity were measured. RESULTS: In 2/3 cadavers, the lacrimal sac is located above the axilla of the middle turbinate, and 1/3 lies below it. A majority of the lacrimal sac (2/3) are located below the entry point of the common lacrimal canaliculus, about 1/3 lies above it. Inner canthal ligament projects on the middle of the lacrimal sac, almost equal to the level of common lacrimal canaliculus. Thirty-two cases (thirty-nine sides) of chronic dacryocystitis were followed-up > 6 months after operation. Thirty-five sides were cured, 2 sides improved and 2 sides ineffective. The cure rate was 89.8%, improve rate 5.1% and ineffective rate 5.1%, respectively, and the total effective rate was 94.9%. CONCLUSIONS: The central position of dacryocystorhinostomy should be 0.2 cm above the front of the axilla of the middle turbinate, to make an curved mucous membrane incision 0.8 cm above and 0. 4 cm below the front of the axilla of the middle turbinate and bone ostium about 1.2 cm x 1.0 cm. It is the best position in endoscopic dacryocystorhinostomy. Locating the inner canthal ligament with a bayonet type forceps to find the projection of lacrimal sac is also a simple and easy method.
