Objective To investigate the pathogenesis of endometriosis by studying endometriosis coexisting with variable genital tract anomalies and analysis the association between obstructive or nonobstructive anomalies with endometriosis.Methods From January 2000 to April 2010,a total of 67 cases of endometriosis coexisting with genital tract anomalies undergoing treatment in Peking Union Medical College Hospital were studied retrospectively.Results According to subtypes of concurrent genital tract anomalies,67 cases were divided into 19 cases in obstructive group and 48 cases in non-obstructive group.(1) Age and symptoms:the mean age were (22 ± 8) years in obstructive group and (32 ± 7) years in non-obstructive group,which reached statistical difference (P ＜ 0.05).The major symptoms were dysmenorrheal or chronic pelvic pain (14/19) and amenorrhea (8/19) in obstructive group.However,in non-obstructive group,the major symptoms were dysmenorrheal or chronic pelvic pain (31％,15/48) and infertility (35％,17/48) and abortion (21％,10/48).(2) Degree and incidence of endometriosis:the moderate or severe endometriosis was 11/19 in obstructive group and 40％ (19/48) in non-obstructive group,which did not show statistical difference (P ＞ 0.05).The incidence of peritoneal endometriosis,ovarian endometriosis,adenomyosis did not show significant difference between two groups (all P ＞ 0.05).The rate of moderate or severe endometriosis coexisting with duplex uterus,uterus bicornis and uterus septus did not show significant difference in non-obstructive group (P ＞ 0.05).Conclusions The severity of endometriosis showed no association with obstructive anomalies.The results implied that there might be other factors involved in pathogenesis of endometriosis.

Objective To investigate clinical features and management of complicated or rare vulvovaginal anomalies derived from urogenital sinus malformation.Methods Medical documents of 6 cases with vulvovaginal anomalies treated in Department of Obstetrics and Gynecology in Peking Union Medical College Hospital in the past 10 years were reviewed retrospectively.According to embryological and anatomical characteristics,the classification system were established.Results This kind of vulvovngihal anomalies was very rare and not enrolled into current diagnosis and treatment system. All patients had a common clinical features:menstruation bleeding and urine from the same outflow tract;and two orifices on perineum were found by bimannal examination,one orifice located under clitoris,the other orifice Was anus.No vagihal vestibule and vulvar were observed between those two orifices.According to clinical features,those 6 cases were divided into 3 types:type Ⅰ Was persistence of distant urogenital sinus with clinical manifestation of simple labial fusion;type Ⅱ was low communication between vagina and urogenital sinus (infrasphincterie),presenting with distal vaginai atresia and urethrovagihal fistula;type Ⅲ was high communication (suprasphincteric) with distal vagihal atresia and more proximal urethrovavihal fistula.Type Ⅲ was frequently associated with severe rectum and anus anomaly,and other malformation as well.All patients were treated by surgical correction.Basically.the principle of operation wag to reconstruct perineal appearance,release the obstruction,and rear the defect and ultimately recovering the normal function.The alternative surgical methods should be considered individually.Conclusions The vulvovnginal anomalies derived from urogenital sinus malformation were complicated clinically.To establish classification system will be benefit for clinicians to make diagnosis and choose appropriate treatment. The individualized surgery should be performed on those patients to restore the structure and function,in the mean time,the factors associated with esthetics.sex and psychics should be considered.

Obiective To explore the risk factors of endometriosis-associated ovarian cancer (EAOC) in women with ovarian endometriosis aged 45 years and older in China. Methods The medical records of total 1038 women aged 45 years and older with a surgicopathological diagnosis of ovarian endometriosis treated at Peking Union Medical College Hospital from December 1994 to December 2014 were reviewed. Histology evaluation determined ovarian endometriosis with (n=30) or without (n=1008) ovarian cancer. Results (1) There were 30 (2.9%, 30/1018) cases confirmed as having EAOC. Clear cell carcinoma (63.3%, 17/30) and endometrioid adenocarcinoma (23.3%, 7/30) were commonly observed subtypes and 70.0%of EAOC patients were at stageⅠ. (2) Compared women with ovarian endometriosis in the same age group,patients with EAOC were older (50.8 vs 48.5 years, P=0.002). There were more in postmenopausal status at diagnosis of EAOC (P＜0.01). There were more found with a mass ≥8 cm (P＜0.01). Women with EAOC had higher prevalence of coexisting endometrial disorders (P=0.003). No differences were found in preoperative CA125 value and infertile or nulliparous women (P＞0.05). Conclusions For women with ovarian endometriosis aged 45 years and older, the subgroup of patients characterized by postmenopausal status and ovarian endometrioma (≥8 cm) have a higher risk of EAOC. Active intervention or intensive follow-up should be considered for this population group, especially for those concurrent with endometrial disorders.

BACKGROUNDCurrently, all the diagnostic indicators for endometriosis lack perfect sensitivity and specificity. According to the characteristic of endometriosis, we analyzed the new biomarker neutrophil-to-lymphocyte ratio (NLR) and the combination of NLR and serum CA-125 to investigate their diagnostic value for identifying stages III and IV endometriosis.

METHODSThe values of serum CA-125 and routine blood tests were collected from 197 patients with endometriosis, 102 with benign tumors and 112 healthy individuals. We investigated the sensitivity and specificity of NLR and its combination with serum-CA-125 for diagnosing stages III and IV endometriosis by using receiver operating characteristic (ROC).

RESULTSThe mean values of NLR, the combination of serum CA-125 and NLR (combination) of the groups with stages III and IV endometriosis were significantly higher than the other two groups. Serum CA-125, NLR, and the combined biomarkers could significantly discriminate the stages III and IV endometriosis group from the other two groups (P < 0.05). NLR shows a lower sensitivity of 57.9% and specificity of 65.2% with a cutoff value at 1.82. And the combination of biomarkers has the highest AUC of 0.949 with a sensitivity of 86.8% and specificity of 92.0% at the cutoff value of 44.40. In addition, for patients with negative CA-125, 55.36% and 53.57% of the patients were able to be diagnosed with endometriosis by using NLR alone and the combination of biomarkers.

CONCLUSIONFor diagnosing stages III and IV endometriosis, the neutrophil-to-lymphocyte ratio is a better adjuvant to serum CA-125, and the neutrophil-to-lymphocyte ratio is valuable in diagnosing stages III and IV endometriosis for patients with negative serum CA-125.

OBJECTIVETo study the value of bacterial cultures of bronchoalveolar lavage fluids (BALF) in children with pulmonary infection.

METHODSBacterial cultures sampled from both sputum and BALF were performed on 80 hospitalized children with pulmonary infection between June 2008 and February 2011.Culture results between the two samples were compared.

RESULTSIn the 80 children with pulmonary infection, bacterial cultures of BALF showed that Viridans Streptococci were found in 72 cases (90%), Neisseria in 41 cases (51%), Streptococcus pneumoniae in 11 cases (14%), Staphylococcus Aureus in 3 cases (4%) and Escherichia coli in 3 cases (4%). The positive rates of Viridans Streptococci in the bacterial cultures of BALF was not significantly different from the bacterial cultures of sputum, but the positive rate of Streptococcus pneumoniae in the bacterial cultures of BALF was significantly higher than in the bacterial cultures of sputum (4%). Moreover, Escherichia coli were found only by bacterial cultures of BALF.

CONCLUSIONSBacterial cultures of BALF are useful in the identification of pathogenic bacteria for pulmonary infection in children. Due to the samples taken from the lesion regions in bacterial cultures of BALF, the results of may be more reliable.

The study was aimed to construct the recombinant adenovirus vectors containing human survivin gene, and to investigate their expression in transfected dendritic cells. Full length cDNA encoding survivin was obtained by PCR amplification from plasmid pcDNA3.0-survivin. The PCR product was restricted, and then inserted into pShuttle-CMV. The plasmids of pShuttle-CMV-survivin were linearized with PmeI, and the fragment containing survivin was ligated with pShuttle-CMV and transfected into E. coli BJ5183. After homologous recombination in bacteria, the extracted plasmid from the positive bacteria were linearized with PacI, transfected into HEK293 cells with liposome Lipofectamine 2000. Then, the harvested adenovirus supernatants were transfected into dendritic cells. The results showed that the recombinant adenovirus-survivin was constructed successfully and its titer was about 2.65 x 10(9) pfu/ml. The expression of survivin in transfected dendritic cells was confirmed by Western blot analysis. It is concluded that the recombinant adenovirus vector containing human survivin was constructed successfully, which may provide preliminary laboratory evidence for anti-leukemia immunotherapy.

Objective To investigate the clinical value of diffusion-weighted imaging (DWI) for evaluating the activity of sacroiliitis in ankylosing spondylitis (AS).Methods Totally 73 AS patients were prospectively enrolled and divided into active group (n=43) and chronic group (n=30) according to Bath ankylosing spondylitis disease activity index (BASDAI) scores and laboratory findings. Conventional magnetic resonance imaging (MRI) and DWI were performed in all subjects. Apparent diffusion coefficient (ADC) values of subchondral lesions in sacroiliac joint were independently measured by two radiologists,and the relative ADC (rADC) values were calculated. ADC and rADC values were compared between active and chronic groups. The efficiencies of ADC and rADC values for differentiating the activity of sacroiliitis were analyzed. In addition,the correlation coefficients of ADC values,rADC values,and BASDAI scores were calculated.Results The ADC and rADC values in the active group were (0.667±0.122)×10 mm /s and (1.715±0.343)×10 mm /s,respectively,which were significantly higher than those of the chronic group [(0.492±0.0651)×10 mm /s and (1.289±0.209)×10 mm /s,respectively)] (P<0.0001). The agreement of measurement results between two radiologists was good,and all the interclass correlation coefficients were >0.81. The correlation coefficients of ADC value and rADC value with BASDAI scores were 0.82 and 0.80,respectively (P<0.0001). The optimal cutoff values of ADC value and rADC value for differentiating AS activity were 0.545×10 mm /s and 1.467×10 mm /s,respectively,The specificity was 81.8% for both indicators,and the sensitivity was 92.0% and 88.0%,respectively.Conclusion DWI is helpful in the quantitative assessment of the activity of sacroiliitis in AS patients.
