Objective To find out and clarify the causes and the pathogens of vulvovagmitis in childhood girls, to determine the clinical treatment. Methods There were 345 cases of childhood girls .ranged from 18 days to 12 years, with symptoms of vulvovagini tis, and their vaginal secretions were examined by routine smear for cleaning degree, trichomonas , Candida and clue cells, gram-stain for neisseria gonorrhoeae, culture for bacteria, mycoplasma urealytium, mycoplasma hominis and chlamydia trachomatis. Results One hundred and nine pathogens were detected(31.6% of the whole cases ), including specific pathogen 70 cases(20. 3% )and non-specif ic pathogen 32 cases(9.3%). Gardnerella was detected most frequently in specific pathogen while enteric bacilli was detected most frequently in non-specific pathogen. Conclusions Non-specific vulvovaginitis is the most frequent cause in childhood vulvovagimtis, and bacterial vaginosis is the mast frequent in specific infection. Symptomatic treatment is effective, but antibiotic treatment should be based on pathogenic findings of vaginal secretions.

Objective To investigate the clinical and MR features of fungal encephalopyosis and fungal granuloma.Methods The clinical and MR data of 10 cases with fungal encephalopyosis and fungal granuloma confirmed by surgical pathology or clinical serum were analyzed retrospectively.Then we analyzed the clinical conditions,MR signals,lesion enhancement,DWI and MRS performance characteristics of the 10 cases.Results Six cases were fungal encephalopyosis,among which 2 cases occurred in the sella turcica after surgery which located in and above the sella turcica.2 cases occurred in the frontal lobe after frontal surgery and 1 case of them was multiple encephalopyosis.2 cases of encephalopyosis without operation history were located in the left frontal lobe and right cerebellum respectively.The abscess walls of these cases were thin and showed high tension.Furthermore,it had annular significant signal enhancement and high signal in DWI scan.One case of huge fungal granuloma located in the frontal lobe and into the sinuses which showed uneven signal enhancement. The Cho level was significantly increased.Three cases of cryptococcal granuloma showed multiple lesions located in the bilateral basal ganglia region and 2 out of them accompanied with cephalomeningitis.Conclusion The MR performance of fungal encephalopyosis was quite similar with bacterial brain abscesses,which makes the differential diagnosis difficult.The brain fungal granuloma MRS may display a significant increase of Cho level which might be related with gliosis.It shows certain characteristics of brain MR performance of cryptococcal granuloma which are multiple lesions,preferential distribution of basal ganglia region and accompanying cephalomeningitis.

Complete resection of liver cancer is the main approach for achieving radical resection,and sufficient remnant liver is essential for avoiding hepatic failure after operation.With the aim of increasing remnant liver volume,a new two-stage technique,associating liver partition and portal vein ligation for staged hepatectomy (ALPPS),recently has been developed.In this article,the initial experience with 1 case of hepatocellular carcinoma who underwent ALPPS at the Zhongshan Hospital in April 2013 was reported.In the first stage,the right portal vein branch was ligated and subsequently the liver parenchyma was dissected along the falciform ligament to isolate the segment Ⅳ and the left lateral lobe.On postoperative day 7,the remnant liver volume was increased from 291 ml to 579 ml,and on postoperative day 8,the second stage operation was performed.During the second stage,the extended right lobe was removed.ALPPS induces a great and fast hypertrophy of the remnant liver,and R0 resection could be performed on patients which was considered unresectable because of small remnant liver volume,without severe postoperative liver failure and has a low mortality.

The aim of this study was to comprehensively investigate the correlations between foliar fungal endophyte communities and effective components accumulations in Salvia miltiorrhiza. Foliar samples of S. miltiorrhiza were collected in 5 different areas. Their fungal endophyte communities and effective component contents were determined by denaturing gradient gel electrophoresis (DGGE) and high performance liquid chromatography (HPLC), respectively. The results showed that, for characteristics of foliar fungal endophyte communities and effective component contents, there were both similarities and differences among the five samples. Correlation analysis of DGGEs' band and 24 effective components revealed a significant correlations (P < 0.01). For examples, 4 bands (15, 18, 23 and 26) were all significantly correlated with the accumulations of caffeic acid, salvianolic acid B, salvianolic acid C and dihydrotanshinone I.

Objective To compare imaging quality and radiation dose on full-field digital mammography (FFDM) system and dual-sided reading CR mammography (DSCRM) system.Methods The TRM of ALVIM statistics phantom was exposed by FFDM system and (DSCRM) with the same radiation dose.The exposure parameters and the entrance surface dose (ESD) were recorded.Then,the phantom was exposed by DSCRM system with different mAs and same kV,and the ESD was recorded.The images obtained above were read by three radiologists on the monitor of diagnosis work station with the same window width and window level.The evaluation of the images were given using a five-level confidence scale.ROC curves were drawn and probability Pdet were calculated.Results The ROC analysis of microcalcifications and masses showed A(z) values of 0.730-0.925 and 0.670-0.945 for FFDM,and 0.632-0.815 and 0.575-0.785 for DSCRM when the radiation dose is 1.36 mGy.The radiation dose with DR system could be reduced compared with dual-sided reading CR system at the same probabilities Pdet,the ESD reduced from 1.63 mGy to 1.36 mGy by 19.8%,the AGD reduced from 0.65 mGy to 0.56 mGy by 16.0%.Conclusions The observable details with FFDM system were proved to be superior to DSCRM system at the same radiation dose.With the similar image quality,the radiation dose of FFDM system was less than the DSCRM system.
