Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases. However, due to its complex pathogenesis, there are no officially approved drugs for NAFLD treatment currently. Therefore, it is extremely urgent to find safe and effective anti-NAFLD drugs. Nowadays, lipid-lowering drugs are the main option for NAFLD therapy, but the clinical efficacy of chemical drugs is also very limited, as well as the frequent side effects or adverse reactions. Traditional Chinese medicine (TCM) has attracted more and more attention in the treatment of NAFLD due to its unique advantages through multiple targets and pathways with few side effects. In recent years, numerous studies have demonstrated that the imbalance of gut microbiota plays an important role in the occurrence and development of NAFLD. This review systematically summarizes the experimental and clinical evidences of TCM active compounds and TCM prescription involved in the regulation of intestinal flora in the treatment of NAFLD in recent years, so as to provide a reference for further exploring the pathogenesis of NAFLD and exploring TCM treatment methods.

OBJECTIVETo study the effect of Angelica sinensis, Salvia miltiorrhiza and Ligustrazine on function of peritoneal macrophages during peritoneal dialysis.

METHODSPeritoneal macrophages of mice were cultured in culture medium (control), peritoneal dialysate (PD), drugs contained PD containing Angelica, Salvia and Ligustrazine combined (PD-ASL) or separated (PD-A, PD-S, PD-L) with concentration of 2 micrograms/ml, 10 micrograms/ml and 100 micrograms/ml, separately for 24 hrs. The nitric oxide (NO) content, methyl thiazolyl tetrazolium (MTT) reducing capacity (MTT-RC) and phagocytosis capacity of macrophages were determined and compared.

RESULTSNO content and MTT-RC of macrophages cultured in PD group were significantly lower than those of the control (P < 0.01), as compared with those in drug contained PD groups, the NO content in the PD-L group and the MTT-RC in the PD-ASL group were higher significantly (P < 0.01). The phagocytosis capacity and NO content in the PD-ASL group were raised along with the increased concentration of drug in PD.

CONCLUSIONAdministering Chinese herbal medicine during peritoneal dialysis has important significance in improving the defense function of peritoneal macrophages, reducing the incidence of peritonitis and enhancing the therapeutic effect of peritoneal dialysis.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

OBJECTIVE: To investigate the influence of commercial peritoneal dialysate (CDS) on function of macrophage. METHODS: Cultured peritoneal macrophages were divided into two experimental groups and their controls.(1) Macrophages were cultured in conditioned culture medium containing 50%CDS (0.139 mol/L glucose) for 24 h. (2)Macrophage were exposed to CDS containing 0.139mol/L glucose for 10, 30 and 60 min respectively, and then cultured in CDS-free medium for 24 h. The nitric oxide (NO) production and MTT in two groups were measured. In each control group, CDS was replaced by same amount of culture medium. RESULTS: NO production and MTT reduction ability (related to cell viability) of experimental groups were remarkably lower than those of controls and the NO production and MTT reduction in 60min CDS-exposed group were lower than that of 10 min and 30 min CDS-exposed group. CONCLUSION: Dialysate may have detrimental effects on viability and other function of macrophage and these effects may related to time length of CDS exposure.

OBJECTIVETo generate a gene delivery plasmid carrying the dominant negative form of the protein phosphatase 2A catalytic subunit a (DN-PP2Aca) driven by a hepatocellular carcinoma (HCC) tissue-specific promoter and investigate its ability to inhibit growth of cultured hepatoma cells.

METHODSThe gene delivery plasmid was constructed by PCR-amplifying DN-PP2Aca from wild-type PP2Aca using site-directed mutagenesis and then ligating the sequence-verified amplicon downstream of an alpha-fetoprotein enhancer and phosphoglycerate kinase promoter (AFpg) in the luciferase reporter vector pGL3-Basic. Following transfection into two AFP+ hepatoma cell lines (HepG2 and HepG3) and two AFP- hepatoma cell lines (SK-HEP-1 and L02), the transcriptional activity of the AFpg-driven DN-PP2Aca plasmid was tested using luciferase reporter gene assay and western blotting. The effect on cell growth was tested using MTT assay. Between group differences were assessed by t-test.

RESULTSThe AFpg-driven DN-PP2Aca plasmid showed high transcriptional activity and protein expression in both HepG2 and Hep3B cells. At 72 h after transfection, the proliferation capacities were repressed by 42.65%+/-3.99% (P = 0.0002) and 39.87%+/-3.91% (P = 0.0002) in AFP+ HepG2 and Hep3B cells, respectively (vs. untransfected). In contrast, the plasmid was transcriptionally inactive in and had no effect on proliferation of AFP- cells.

CONCLUSIONThe AFpg-driven DN-PP2Aca plasmid exhibits selective cytotoxicity against AFP+ hepatoma cells, and may represent a useful gene therapy strategy to treat HCC.

OBJECTIVETo explore a method to repair larger cleft palate and lengthen soft palate without oral palate raw surface and scar formation, reduce the effect on maxilla and dental arch development.

METHODSA modified double opposing Z-plasty was used to lengthen soft palate and the nasal palate was closed by using large turn-over mucoperiosteal flaps on the oral surface of the junction of the hard palate and soft palate, oral raw surface on the palate was closed by a buccal myomucosal island flap.

RESULTSThirty-six palates have been repaired by this procedure, all of which had satisfactory results without flap necrosis, infection, difficulties in opening mouth and facial nerve injury except two post-operative fistulas. Eight patients were followed up and all display complete velopharyngeal closure.

CONCLUSIONSUsing unilateral buccinator myomucosal island flap with double opposing Z-plasty to repair wider palatal cleft can get a satisfactory soft palate lengthening. At the same time it can avoid bone surface exposing and scar formation; it is a safe and reliable procedure.

OBJECTIVETo analyze the factors affecting pathologic complete response (pCR) to neoadjuvant chemotherapy (NAC) in breast cancer patients.

METHODSA retrospective cohort study was carried out to analyze the clinical data of 141 breast cancer patients treated with neoadjuvant chemotherapy. The factors affecting pCR and the changes of tumor receptor status before and after treatment were analyzed.

RESULTSAmong all the 141 patients, 21 patients (14.9%) achieved pCR. The rate of pCR achieved by regimens of anthracycline combined with taxane was higher (16.8%, 19/113) than that by anthracycline-containing regimens (7.1%, 1/14). The dose intensity of anthracycline had a significant correlation with pCR rate (P < 0.05). The pCR rate in the relative dose intensity of taxane ≥ 0.85 arm was higher than that of < 0.85 arm (P = 0.02). Eighty patients (56.7%) had completed more than 4 cycles of chemotherapy and the median time to achieve pCR was 6 (3 to 10) cycles. The pCR rate had a significant difference between patients < 6 and ≥ 6 cycles (7.1% vs. 22.5%,P = 0.01). Multivariate analysis showed that tumor size measured by palpation ≤ 5 cm and ≥ 6 chemotherapy cycles were significantly related with pCR rate (P < 0.05). In all the 21 pCR patients, the pre-treatment ER(-), PR(-), HER-2(-) statuses were in 14, 14 and 17 patients, respectively. The status of ER, PR, HER-2 of most patients (74.2%, 69.7% and 87.7%, respectively) was not changed after treatment. Among the patients with changes in receptor status, ER changed from negative to positive was in the majority (37.1%, 13/35 vs. 12.9%, 4/31, P < 0.05), and the percentage of changes in PR and HER-2 status had no significant differences.

CONCLUSIONSThe regimens of anthracycline combined with taxane can achieve a higher pCR rate. The lymph node and receptor status before therapy have no significant correlation with pCR. Patients who have primary tumor size ≤ 5 cm, ≥ 6 chemotherapy cycles and enough dose intensity are easier to achieve pCR. The receptor status before and after therapy should be determined, and according to any positive results, physicians can chose HER-2 targeted therapy and/or endocrine therapy after surgery to benefit the patients.

OBJECTIVETo study the anatomy of angular nerve (AN), so as to provide safe approach for the denervation surgery of corrugator supercilii, depressor supercilii and procerus.

METHODS10 fresh cadaver (20 sides)were perfused and fixed with formalin. Dissection was performed in the 10 x operating microscope. The plexus of the zygomatic branch and the buccal branch were detected to confirm the AN. The relationship of AN with the surrounding blood vessels was observed. We tracked AN until it entered corrugator supercilii, depressor supercilii and procerus.

RESULTS(1) AN was classified into I, II, III type according to its formation pattern. Type I (20%, 4/20 sides) AN is single, which is mainly from the plexus of buccal branch plus the zygomatic branch from the orbicularis oculi muscle. In type II (20%, 4/20 sides), the single AN was formed by buccal branch plexus and zygomatic branch plexus in the "Four Muscle Gap". In type III (60%, 12/20 sides), the AN had two branches in the "Four Muscle Gap". (2) The three types AN passed inferior to the support ligament at the suborbital part, and then transversed medial to the support ligament at the medial canthus, along the vessels of medial canthus. (3) The branch of AN enters the depressor supercilii or procerus 2.19 to 4.28 mm above the medial canthus ligament. The backward branch enters the levator labii superioris alaeque nasi 6.89 to 9.38 mm below the medial canthus ligament.

CONCLUSIONSThe approach of denervation surgery for AN should be performed medial to the support ligation, between 2.19 mm above the medial canthus and 6.89 mm below the medial canthus.
