Objective Previous studies regarding the effects of tamoxifen ( TAM) on the thin endometrium are rare .The aim of this study was to explore the effects of TAM on patients with thin endometrium undergoing frozen thawed embryo transfer ( FET ) . Methods One hundred and thirty three patients with thin endometri-um undergoing FET treatment were recruited from January 2014 to June 2016, who canceled embryo transfer ( ET) or after FET due to thin endometrium in natural cycle or hormone replacement therapy cycle .Patients were randomly divided into letrozole ( LE,n=72) group or tamoxifen (TAM,n=61) group.All of the patients started to have oral pills of Estradiol Valerate 4 mg/d on the third day of menstruating cycles , then 6mg/d on the eighth day ,after 10~12 days then having ultrasonic monitoring of endometrial thickness and blood estradiol (E2), progesterone levels, It′s called endometrial preparation for hormone replacement cycle .To letrozole, tamoxifen group,the way of endometrial preparation were as follows:patients started to have oral pills of LE 2.5mg/d,TAM 40 mg/d on the third day of menstruating cycles for 5 days, then having ultrasonic monitoring and used drug of human chorionic gonadotropic hormone ,It′s called HCG day .After the dominant follicle ovulation then took progesterone intramuscular injection 40 mg/d, oral progesterone 20 mg/d to change endometrium ,then to transplant cleavage embryos or blastocysts after taking 3 or 5 days of progesterone , It′s called embryo transplanting day .The way of TAM endometrium preparation was called TAM cycle .The general data , hormone levels and clinical out-come between two groups were analyzed . Results The serum estradiol level of LE group both on HCG and transfer day [(1193.80± 629.64)ng/L vs (2776.30±157.34)ng/L;(1195.90±820.30)ng/L vs (2129.40±1208.71) ng/L,P=0.000] were statistically lower, serum luteinizing hormone level were statistically higher than TAM group [(20.48±15.50)IU/L vs (10.59±8.34)IU/L,P<0.05];im-plantation rate of LE group were statistically lower than TAM (39.32%vs 45.83%,P=0.001).The endometrial thickness and serum E 2 and P levels in TAM cycles were significantly higher compared with those in hormone replacement therapy cycle [(8.49±1.36)mm vs (6.43±0.96)mm,P=0.018]. Conclusion Tam compared LE with patients of thin endometrium undergoing FET can increased en -dometrial thickness and improve implantation rate ,thus Providing a new solution to thin endometrium .

Papillon-Lefèvre syndrome (PLS) is a very rare syndrome of autosomal recessive inheritance characterized by palmoplantar hyperkeratosis and a severe destructive periodontitis, leading to premature loss of both primary and permanent dentitions. This article reported a boy who was diagnosed as having PLS.

OBJECTIVEThis study aims to investigate the gene mutational characteristics of cathepsin C (CTSC) gene in a Chinese patient with Papillon-Lefèvre syndrome (PLS), then further confirm the genetic basis for the phenotype of PLS, and obtain genetic information that can be used as guide in the diagnosis and treatment of PLS.

METHODSWith their consent, peripheral blood samples were obtained from the proband and his family members (his parents and older sister) for genomic DNA extraction. The coding region and exon/intron boundaries of the CTSC gene were amplified and sequenced using poly-merase chain reaction and direct sequencing of DNA.

RESULTSCompound heterozygous mutations of CTSC gene were iden-tified in the patient. The proband carries one heterozygous nonsense mutation c.754C>T in exon 5 and one heterozygous missense mutation c.1040A>G in exon 7. Both parents were heterozygous carriers without the clinical symptoms of PLS. None of the mutations were detected in the proband's sister.

CONCLUSIONSThe study proves that mutations of CTSC gene are responsible for the phenotype of Papillon-Lefèvre syndrome.

Objective To investigate the onset of liver inflammation and related predictive factors in patients with HBeAg-positive chronic hepatitis B virus (HBV) infection who have normal alanine aminotransferase (ALT) and a high viral load. Methods A retrospective analysis was performed for the clinical data of 183 patients with HBeAg-positive chronic HBV infection who had normal ALT and a high viral load and were treated from October 2008 to May 2015, and according to the results of liver biopsy, they were divided into hepatitis group and non- hepatitis group. The t -test or Mann-Whitney U testwas used for comparison of normally distributed continuous data between groups, the chi-square test was used for comparison of categorical data. The predictive factors were analyzed by univariate binary logistic regression, the multivariate binary logistic regression was carried out by stepback method, and the cut-off values were analyzed by receiver operating characteristic curve (ROC) and Jordan index. Results There were 37 patients (20.2%) in the hepatitis group and 146 patients (79.8%) in the non-hepatitis group. Compared with the non-hepatitis group, the hepatitis group had a significantly lower proportion of male patients (45.9% vs 68.5%, χ 2 =6.508, P =0.011), a significantly higher level of aspartate aminotransferase [24 (21.25~35.55) U/L vs 21.2 (18.08~ 24.65) U/L, Z =-3.344, P =0.001], and a significantly lower log(HBsAg) value [4.4(4.28~4.49) vs 4.46(4.4~4.74), Z =-2.184, P =0.029]. Log(HBsAg) value was a predictive factor for hepatitis (odds ratio=0.077, P =0.017), and the cutoff value of HBsAg was 33884.4I U/mL. Conclusion Among the patients with HBeAg-positive chronic HBV infection who have normal ALT and a high viral load, 20.2% have liver inflammation, and HBsAg may be a predictive factor for liver inflammation.

Objective: To investigate the correlation between the frequency and function of early plasmacytoid dendritic cells (pDC) and the treatment response in patients with HBeAg-positive chronic hepatitis B receiving entecavir (ETV). Methods: Patients with HBeAg-positive chronic hepatitis B were enrolled. Antiviral therapy with ETV, serum serological markerso hepatitis B virs (HBV) infection and liver function (HBV DNA load, HBsAg/anti-HBs, HBeAg and anti-HBe levels, and ALT levels) were monitored every three months before and during treatment; the efficacy of ETV was assessed by changes in the level of HBV DNA. Peripheral venous blood was collected before treatment, at 12 weeks and 24 weeks, respectively. Flow cytometry was used to detect the frequency of peripheral blood pDC and the surface co-stimulatory molecule CD86. The baseline and early treatment (12 weeks and 24 weeks) pDC frequency and functional changes were analyzed. Results: Of the 100 patients with chronic hepatitis B, 45 patients received ETV treatment and 48 weeks of follow-up. Within 48 weeks of ETV treatment, HBsAg levels decreased by 0.53±0.78 log IU/mL; HBeAg decreased by 816.61S/CO, and HBeAg seroconversion occurred in 4 cases; HBV DNA content decreased by 6.04±1.12 log IU/mL, in 33 cases (73%) the HBV DNA became undetectable, in 43 cases ALT kept normal continuously for more than 3 months. In the early stage of ETV treatment, pDC% increased significantly, CD86+ pDC%, CD86MFI and CD86ABC showed no significant changes. In ETV-treated HBV DNA responders, pDC% increased significantly, CD86+ pDC%, CD86MFI and CD86ABC showed no significant changes; HBV DNA non-responders had a significant increase in pDC%, but CD86+ pDC% decreased significantly, and CD86MFI and CD86ABC showed no significant changes. The decrease in HBsAg and HBeAg levels in ETV treated patients was not significantly associated with early pDC%, CD86+ pDC%, CD86MFI and CD86ABC changes. Conclusions ETV treatment can directly inhibit the replication of HBV DNA, but does not enhance the function of immune cells.
