OBJECTIVETo investigate the expression of a novel biomarker, human short-type myofibrillogenesis regulator-1 (MR-1S), in ovarian carcinoma and explore its biological significance.
METHODSThe MR-1S mRNA levels were analyzed by reverse transcription polymerase chain reaction (RT-PCR) in 23 specimens of ovarian cancers and 20 specimens of control ovarian tissues. The expression of MR-1S in these specimens was detected by real-time PCR and immunohistochemical analysis. In addition, the expression of MR-1S in ovarian cancer SKOV3 cells was determined by immunocytochemisty. MR-1S mRNA and protein level of SKOV3 cells was compared in the two groups treated by carboplatin and paclitaxel at 24 h, 48 h and 72 h, respectively. Furthermore, the expression of MR-1S was analyzed in liner concentration range of the anti-cancer drug, and the potential relation between MR-1S expression and cell apoptosis rate was predicted.
RESULTSThe level of MR-1S mRNA was significantly higher in ovarian cancer tissues than those of control tissues by RT-PCR and Real-time PCR analysis. MR-1S protein was overexpressed in ovarian cancer tissues with a positive rate of 78.3% (18/23) than that in the control tissues (30.0%, P<0.05) through IHC analysis. The expression of MR-1S was markedly decreased by treatment with carboplatin and paclitaxel, and there was a direct correlation between MR-1S expression and apoptosis rate, especially in a liner concentration range of paclitaxel at 48 h.
CONCLUSIONMR-1S is highly expressed in ovarian cancer cells and tissues, and it may be a promising biomarker for diagnosis and a new target for ovarian cancer therapy.

OBJECTIVETo extract corosolic acid from loquat leaves for medical use.
METHODSLoquat leaves were boiled in water to remove the water-soluble substances followed by 3 cycles of extraction with 25% aqueous methanol for 30 min and then by 95% aqueous methanol for 1 h at 80 degrees celsius;. After cooling at room temperature and filtration, the extract was treated with activated carbon to remove chlorophyll, and the liquid was filtered and concentrated to allow precipitation. The sediment was washed to obtain the total crude triterpene acid, which was further dissolved with methanol and purified by high-performance liquid chromatography (HPLC). The fractions including corosolic acid were collected, concentrated with vacuum distillation, and dried to obtain corosolic acid product, which was analyzed with HPLC.
RESULTSHPLC analysis of the extracts showed that the percentages of corosolic acid were 4.66%, 2.42%, and 24.18% in crude corosolic acid extracted with methanol, boiling water, and 95% aqueous methanol, respectively. After purification with HPLC, the purity of corosolic acid in the product exceeded over 80%.
CONCLUSIONThe optimal extraction method, which is convenient and cost-effective, is established for extracting corosolic acid from loquat leaves for medical use.

To evaluate the effects of glutamine-supplemented parenteral nutrition (PN) and probiotics in adult autoimmune enteropathy (AIE) patients. Four adult AIE patients were identified from April 2006 to January 2012. Clinical and nutritional data were obtained from the patients' medical records. Glutamine-supplemented PN started immediately when the AIE diagnosis was confirmed. The total PN duration was 351 days. According to the PN prescription, the average caloric intake ranged from 20 to 25 kcal/kg/day, and the protein intake ranged from 1.2 to 1.5 g/kg/day. Alanyl-glutamine (20 g/day) was administered to AIE patients for 4 weeks followed by a 2-week break, and this treatment schedule was repeated when PN lasted for more than 6 weeks. Body weight gain and an increased serum albumin level were achieved after PN, and defecation frequency and quality also improved. Each patient received oral supplements, 250 mL of Ensure and two probiotics capsules (each capsule containing 0.5x10(8) colonies) three times a day when enteral nutrition started. Three AIE patients were successfully weaned off PN, and one patient died of pneumonia. Glutamine-supplemented PN and probiotics show promise in managing patients with AIE and related malnutrition.

OBJECTIVETo evaluate the anginal attack-relieving efficacy and safety of Kuanxiong Aerosol (KA) in patients with coronary heart disease (CHD).
METHODSA total of 780 patients confirmatively diagnosed as CHD angina from November 2011 to December 2012 in 13 medical centers in the mainland area were assigned to 2 groups by blocked randomization, the treatment group (376 cases) and the control group (374 cases). When the angina attacked, patients in the treatment group received sublingual spray three times, 0.6 mL each time, while those in the control group sublingually dissolved Nitroglycerin Tablet (NT), 0.5 mg each tablet. The effective rate of angina relief, efficacy of electrocardiogram (ECG), and the incidence of adverse reactions were observed.
RESULTSThe 3 min and 5 min remission rates of angina attack were 53.72% (202/376) and 94.41% (355/376) in the treatment group, and 47.86% (179/374) and 90.64% (339/374) in the control group. The 95% confidence interval (CI) of the difference between the 2 groups of 3 min and 5 min remission rates of angina attacks were [(-1.84%, 12.32%) and (-1.33%, 6.85%) respectively, P > 0.05]. The total improvement rates of ST-T changes in the treatment group and the control group after treatment were 74.07% and 73.13% respectively (P > 0.05). The adverse reaction rate was 9.31 (35/376 cases) in the treatment group and 22.46% (84/374 cases) in the control group (P < 0.01).
CONCLUSIONKA was not inferior to NT in relieving anginal attacks and improving ischemic ECG changes, and had obviously less adverse reaction.

PURPOSE: To provide a systematic review with meta-analysis for addressing the relationship between fecal bile acids (FBAs) and colorectal cancer. MATERIALS AND METHODS: Electronic databases were searched for all observational studies that examined the relationship between FBAs and colorectal cancer or adenoma, and calculated weighted mean difference (WMD) and 95% confidence interval (CI). Publication bias was assessed with funnel plot. RESULTS: Twenty case-control or cohort studies were identified. All studies were pooled to assess the relationship between total FBAs and cancer/adenoma of the large bowel, however, no association was seen (WMD 0.61mg/g freeze-dried feces; 95% CI: -0.35-1.57). Significantly increased concentration of chenodeoxycholic acid (CDCA) was seen while pooling to assess the relationship between CDCA and cancer/adenoma of the large bowel (WMD 0.13 mg/g freeze-dried feces; 95% CI: 0.01-0.25), especially for colorectal cancer (WMD 0.28mg/g freeze-dried feces; 95% CI: 0.10-0.46). However, no significant differences in deoxycholic acid (DCA), lithocholic acid (LCA), and primary and secondary bile acids, were seen between patients with cancer and patients with matched controls regardless of fixed and random effects models. CONCLUSION: CDCA might play a role in the etiology of colorectal cancer.
