OBJECTIVE To investigate the infection status and drug-resistance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) isolated from female genitourinary tract.METHODS A total of 1890 female genitourinary tract specimens were collected from Jan 2003 to Dec 2006.The results of mycoplasma cultivation and susceptibility test were analyzed retrospectively.RESULTS Among 1890 specimens,there were 756 with positive mycoplasma cultivation and the positive rate was 40.0%.The positive ratio was the highest at the age of 21 to 40.From 12 commonly used antibiotics,the sensitivity to tetracyclines was the highest,and then was to macrolides.Four quinolones all showed the higher resistance,and their sensitivity rates were all below 50%.CONCLUSIONS The drug-resistance of mycoplasma in female genitourinary tract is greatly severe.The clinical doctors should think highly of it.

Objective To observe the uhrasenographical characters of liver and spleen of residents and their changes in endearic areas of schistosomiasis japonica in Poyang Lake region.Jiangxi Province and to explore the value of ultrasonography for assessment of the morbidity of the disease.Methods All permanent residents aged above 3 years old were examined by ultrasonography and Kato-Katz method.Results The schistosome positive rates of fecal examinations decreased obviously from 16.29%in 1995 to 8.54%in 2007(P<0.01).However,the rates of hepatomegaly and splenomegaly between 1995 and 2007 were not significantly changed(P>0.05),with the rates of 8.82% and 20.33% in 1995 and 8.54% and 21.34% in 2007,respectively.The abnormal rate of portal vein diameter decreased significantly.from 32.47%in 1995 to 6.50% in 2007.The abnormal rate of liver parenehyma increased remarkably(P<0.01),from 34.85% to 51.83%.The changes of liver parenchyma Grade I showed a bidirectional trend,29.90% of them chased into Grade 0(normal image on ultrasonngraphy),and 34.02% changed into Grade 2 and above.The abnormality of various indices of uhrasonography examinations were related to age,occupation and schistesome infection status.Conclusions Ultrasonography can show the damages of liver and spleen of patients infected with Schistosoma japonicum directly.but it is necessary to study further on the sensitive indices that reflecting early pathological changes and the best combination of the indices for the assessment of schistosomiasis-related morbidity.

Objective To investigate the cachexia morbidity among hospitalized patients with digestive system cancer and evaluate its impact on clinical outcomes.Method By analyzing the clinical data of 5 118 hospitalized patients with digestive system cancer in Zhongshan Hospital,Fudan University from January 2012 to December 2013,we investigated the cachexia morbidity and compared the clinical outcome between cachectic patients and noncachectic patients.Results The overall cachexia morbidity of hospitalized patients with digestive system cancer was 15.7％ (803/5 118).The highest cachexia morbidity was 34.0％ (89/173),found in patients with pancreatic cancer.In cachectic group and non-cachectic group,the overall completion rate of radical resection was 67.1％ (539/803) and 74.5％ (3 214/4 315),respectively (P =0.000).Compared to the non-cachectic group,the cachetic group had significantly longer postoperative hospital days [(11.5 ±6.2) d vs (9.4 ±4.9) d,P =0.003],slower postoperative recovery of bowel function [(3.4 ±0.9) d vs (3.2 ±0.8) d,P =0.013],longer postoperative time to intake semifluid [(4.4 ± 1.5) d vs (3.9 ± 1.3) d,P =0.002],and more postoperative complications in 28 days after surgery [8.9％ (48/539) vs 5.8％ (186/3 214),P=0.006].After surgery,131 patients in the cachectic group were transferred to the ICU,and 646 patients in non-cachectic group transferred to the ICU (24.3％ vs 20.0％,P=0.026).Compared to the non-cachecic group,the reoperation rate [3.2％ (17/539) vs 1.5％ (48/3214)],ventilator support rate [8.0％ (43/539) vs 5.7％ (184/3 214)],and mortality [2.4％ (13/539) vs 1.1％ (35/3 214)] of the cachectic group were all significantly higher (P =0.006,0.042,0.011).Conclusions Cachexia is common in hospitalized patients with digestive system cancer,especially in patients with pancreatic cancer.Cachexia has negative impact on the clinical outcomes.

Objective To explore the risk factors of Schistosoma japonicum infection in the residents in Xingzi County,Ji?angxi Province. Methods Six administrative villages from different areas were randomly selected by the cluster sampling meth?od as the study sites in Xingzi Country in 2013,and all the residents aged 5 years or above were investigated epidemiologically, and the schistosome infection was surveyed by Kato?Katz technique. The risk factors of schistosomiasis were analyzed by using the Chi?square test analysis and multivariate Logistic regression model. Results In 2013,there were 2 050 residents received the stool examination and 146 persons were positive,the schistosome infection rate was 7.1%. The Chi?square test showed that gender,age,occupation and education level were associated with the population infection rate(χ2=26.485、16.836、25.700、90.805,all P<0.05). The multivariate Logistic regression mode showed that the probability of schistosomiasis for the male was 3.041 times as much as that for the female;the probability of schistosomiasis for the illiteracy and primary education level crowd was 8.870 times as much as that for the college degree or above crowed;the probability of schistosomiasis for the junior middle school education level crowd was 5.598 times as much as that for the college degree or above crowed;the probability of schistoso?miasis for the high school education level crowd was 2.995 times as much as that for the college degree or above crowed;the probability of infection of fishermen was the highest,which was 3.053 times as much as that for the other professional crowds. Conclusions The risk factors of schistosome infection mainly include gender,occupation and the education level. We should strengthen the health education of schistosomiasis control,protection against the infested water contact,and so on.

Objective Detecting of spermatozoal total RNAs by laboratory on chip gel electrophoresis so that it could provide better total RNAs for the sequent experiments, and spur the development of spermatozoal molecular biology. Methods Sperms of healthy adults were collected and then total RNAs were extracted by RNeasy mini kit(QIAGEN), detection and quality control were performed by loboratory on chip gel electrophoresis system. Meantime, the control RNAs were extracted from lymphocytes. Results It was found that there were a plenty of genes expressed in healthy sperms. Electrophoretic graphs showed that the total RNAs of spermatozoal had 2 bands which went ahead a little comparing to the normal somatic cells. The former peak appeared keenness, and the latter was broad and showed like a reversed U. The ratio of them was largely more than 2, no extra peaks were found in electrophoretic graph. Conclusion A simple,intuitionistic method to detect and control the quality of the healthy adults' spermatozoal total RNAs had been successfully constructed by using laboratory on chip gel electrophorosis.

OBJECTIVETo evaluate the safety and short-term outcomes of laparoscopic-assisted surgery for rectal cancer by comparing the efficacy of laparoscopy and open surgery.

METHODSClinical data of patients with rectal cancer treated by laparoscopy or open surgery in Zhongshan Hospital from April 2011 to June 2012 were analyzed retrospectively, and the clinical outcomes between the two groups were compared.

RESULTSNinety-six rectal cancer patients undergoing laparoscopic surgery(LS) were enrolled. A total of 216 rectal cancer patients underwent open surgery(OS). There was no operative death in both groups. In LS and OS group, the overall completion rates of TME were 86.4%(83/96) vs. 89.3%(193/216)(P>0.05) respectively, and the overall anal reservation rates were 78.1%(75/96) vs. 75.0%(162/216)(P>0.05) respectively. The mean distance to proximal resection margin and distal resection margin respectively were (10.3±4.1) cm vs.(10.0±4.3) cm(P>0.05) and (3.4±0.9) cm vs. (3.6±1.4) cm(P>0.05) respectively. The mean number of harvested lymph nodes respectively were (12.8±5.2) vs.(13.7±6.4)(P>0.05). Compared to OS, LS presented less blood loss [(98.0±28.7) ml vs. (175.0±41.0) ml, P<0.05], shorter postoperative hospital stay [(9.4±4.9) d vs.(11.6±6.2) d, P<0.05], quicker postoperative recovery of bowel function[(2.7±0.9) d vs. (3.4±0.9) d, P<0.05], shorter postoperative time to intake semi-solid[(3.7±1.2) d vs. (4.4±1.5) d, P<0.05], less postoperative complications(15.6% vs. 25.9%, P<0.05), but longer operative time[(155.7±48.4) min vs. (120.0±26.7) min, P<0.05]. Postoperative follow-up was 6 to 24 months, and the local recurrence of LS and OS was 2.1% and 2.3%(P>0.05).

CONCLUSIONLaparoscopic surgery can obtain the same radical efficacy for rectal cancer as compared to open surgery.
