Objective To summarize the experience of laparoscopic operation in the treatment of ovarian cysts. Methods Clinical data of 386 patients with ovarian cysts treated laparoscopically from July 1999 to December 2004 in this hospital were retrospectively analyzed. Results Laparoscopic operation was successfully performed in 384 cases, while a conversion to open surgery was required in 2 cases because of previous operation history or pelvic adhesions. The mean intraoperative blood loss was 20.6 ml (range, 10~60 ml) and the mean operating time, 55 min (range, 20~140 min).The mean postoperative hospital stay was 3 days(range,2~5 days).In a follow-up for 1~60 months (mean, 24 months) in 194 cases, pelvioscopy and B-ultrasonography examinations revealed normal findings. Conclusions Laparoscopic operation for ovarian cysts is an effective and safe method. It is characterized with minimal invasion, quick recovery and short hospitalization.

Objective:To determine the differences of age, eruption sequence and gender of permanent teeth in children and adolescents in Xi'an, China. Methods:Cross-sectional data on permanent teeth eruption were collected from children aged 3~15 in pre-school, primary and secondary school. The subjects were drawn by multistage random sampling from the school registers. There were 6 712 subjects involved in present survey, including 3 604 boys and 3 108 girls. The data were subjected to probit regression analysis. Results:The median age of tooth eruption in girls was earlier than that in boys. Although the range of years during which the permanent teeth erupted was similar in both sexes, i.e. 6~12 years, the sequence of the tooth eruption was differed. All mandibular teeth, with the exception of first and second premolars in both males and females, tended to erupt earlier than their maxillary counterparts. Conclusion:The findings seem to be different from earlier studies done in the other parts of China.

BACKGROUND:Ten-eleven translocation (TET) family proteins are recently discovered DNA dioxygenases that convert methylcytosine to hydroxymethyl cytosine, which is essential for regulating cel proliferation and differentiation, but the expression pattern of TET family proteins in human dental pulp cel s is stil unclear. OBJECTIVE:To investigate the expression pattern of TET family proteins during the differentiation of human dental pulp cel s. METHODS:Cel ular distribution and expression of TET family proteins were determined by immunofluorescence in human dental pulp cel s that were cultured and isolated using digestion method. The protein levels of TETs during cel passage (P1-P7) were detected with western blot assay, and their potential changes during odontogenic induction (7 and 14 days) were confirmed using real-time quantitative PCR and western blot analyses at mRNA and protein levels, respectively. RESULTS AND CONCLUSION:Al TETs were expressed in the nucleus and the cytoplasm of human dental pulp cel s During serial cel passage, TET1 protein expression was increased until the 6th passage, TET2 significantly increased at the 2nd and 3rd passages and then decreased (P<0.05), and TET3 showed no statistical y significant change (P>0.05). Both mRNA and protein expression levels of al TETs were elevated during odontogenic induction (P<0.05). These results indicated that TETs may contribute to cel differentiation of human dental pulp cel s.

Objective To assess the association of subclinical thyroid dysfunction with fractures. Methods Medline, Embase, Pubmed, Cochrane Library, CBM, CNKI, Wan Fang, and VIP databases were systematically searched from January 1990 to August 2015 to identify prospective cohort studies which have studied the risk of fracture in patients with subclinical thyroid dysfunction. The relative risks ( RR) of cohort studies were pooled respectively, depending on the result of heterogeneity test among the individual studies search. The Stata (version 13. 0) software was used for meta-analysis. Results Nine prospective cohort studies including 292460 participants were identified as eligible for the meta-analysis. RR of subclinical hyperthyroidism for fracture was 1. 39(95%CI 1. 24-1. 55);for hip fracture, RR was 1. 24(95%CI 1. 10-1. 40);for nonspine fracture, RR was 1. 32 (95%CI 1. 09-1. 60). Different gender for subclinical hyperthyroid was associated with higher fracture rates:for females, RR was 1. 15(95%CI 1. 04-1. 27); for males, RR was 1. 31 (95% CI 1. 08-1. 59). The incidence of fracture in patients with subclinical hyperthyroidism was higher during the follow-up. For subclinical hypothyroidism, the RR was 1. 21(95% CI 1. 03-1. 42). Subgroup analysis indicated that there were significant differences between endogenous/exogenous subclinical hyperthyroidism and euthyroid, but no differences between endogenous/exogenous subclinical hypothyroidism and euthyroid were found. Conclusion Subclinical hyperthyroidism is associated with an increased risk of fracture in the population, especially hip fracture and nonspine fracture. During the course of subclinical hyperthyroidism, the incidences of fracture should be noticed both in females and males. However, there is no evidence which could prove a definite association between subclinical hypothyroidism and the risk of fracture.

By using the high resolution mass spectrometer TripleTOF 5600 , three kinds of standard proteins including bovine serum albumin ( BSA) , ovalbumin ( OVA) and lysozyme C( LYZC) were analyzed, and the correlationship between the ion intensity of mass spectrometry and the relative content of protein sample was investigated. The protein samples were digested by trypsion and diluted to 1-1024 fmol in 7 μL. The ion counts per second ( cps) were used to stand for the amounts of proteins and peptides. Then the correlation between sum of ion intensity ( cps) of all the peptides, number of peptides detected and the amount of proteins was investigated. By comparing the change of values of the same sample in three parallel experiments, a linear relationship between these indexes and the amount of proteins within 1-1024 fmol was found when the cps was more than 1000. Usually, the maximal ion intensity was no more than 1. 5 times of the minimum value for same peptide in triplicate experiments, which suggested that the 3 times or more change of ion intensity was the minimum threshold to determine the differences of proteins amounts in different samples. This study provides a relative quantitative analysis method using qualitative data of high resolution and high scan speed mass spectrometry, which can quickly and easily provide reference for biological and medical research.
