OBJECTIVETo explore the Chinese medicine syndrome type distribution in patients with polycystic ovary syndrome (PCOS) and its relationship with sexual hormones.

METHODSChinese medicine syndrome types of 212 PCOS patients were differentiated and sorted by adopting fuzzy mean C clustering method, and their relationship with the indices of sexual hormones detected on the 3rd to 5th day of menstrual cycle was analyzed, with the values got from 20 healthy women for controls.

RESULTSIntermingling syndromes were commonly seen in PCOS patients. Shen-deficiency syndrome (presented in 64 patients) and Gan-qi stagnancy syndrome (61 patients) were the dominance, accounting for 30.2% and 28.8% respectively, significantly higher than that of other syndromes (P < 0.05), which were Pi-deficiency syndrome (41 patients, 19.3%), phlegm-dampness syndrome (33 patients, 15.6%) and blood stasis syndrome (13 patients, 6.1%). Levels of estradiol (E2), testosterone (T), luteinzing hormone (LH), dehydroiso-androsterone (DHEA-S) and prolactin (PRL) were higher, while the level of sexual hormone binding protein (SHBG) was lower in PCOS patients than those in control, follicular stimulating hormone (FSH) level in patients of Shen-deficiency syndrome and phlegm-dampness syndrome was high than that in control (P < 0.05 and P < 0.01). However, no significant differences were found in comparing the various sexual endocrinal indices between patients with different syndrome types (P > 0.05). Besides, the level of PRL was positively correlated with LH and E2 levels in patients.

CONCLUSIONChinese medicine syndromes presented in patients with PCOS are mostly intermingling, Shen-deficiency and Gan-stagnancy are the basic syndromes, and there is some correlation between syndrome type and sexual hormone levels.

OBJECTIVETo investigate the protective effects on allografts and the possible mechanism of adeno-associated heme-oxygenase-1 (AdHO-1) gene therapy against chronic rejection injury.

METHODSEx vivo AdHO-1 gene therapy was performed in vascular and renal transplantation models. The structure and function, the expression of therapeutic genes and proteins, and the immune modulation were analyzed.

RESULTSAdHO-1 gene therapy protected renal transplant against chronic rejection, but the effect was not as remarkable as that in vascular transplant. The transfected empty vehicle aggravated chronic rejection damage in renal transplantation. AdHO-1 decreased the infiltration of macrophages and CD4(+) T cells.

CONCLUSIONSAdHO-1 gene therapy can lessen damage of chronic rejection in allografts. It plays roles by protecting transplants, down-regulating immune response and inducing immune deviation.

Lynch syndrome (LS), an autosomal dominantly inherited disease previously known as hereditary non-polyposis colorectal cancer (HNPCC), leads to a high risk of colorectal cancer (CRC) as well as malignancy at certain sites including endometrium, ovary, stomach, and small bowel (Hampel et al., 2008; Lynch et al., 2009). Clinically, LS is considered the most common hereditary CRC-predisposing syndrome, accounting for about 3% of all CRC cases (Popat et al., 2005). LS is associated with mutations of DNA mismatch repair (MMR) genes such as MLH1, MSH2, MSH6, PMS2, and EPCAM (Ligtenberg et al., 2009; Lynch et al., 2009), which can trigger a high frequency of replication errors in both microsatellite regions and repetitive sequences in the coding regions of various cancer-related genes. Immunohistochemistry (IHC) tests followed by genetic analysis of these mutations play a significant role in diagnosis, treatment determination, and therapeutic response prediction of LS (Lynch et al., 2009; Alex et al., 2017; Ryan et al., 2017). Here, we report substitution of one base-pair in exon 1 of MLH3 (c.1397C>A) and a frameshift mutation in exon 19 of MLH1 (c.2250_2251ins AA) in a 43-year-old Chinese male with an LS pedigree.
