The paper first made a review of the literature on the pharmacology and clinical use of cisplatin. An analysis was then made of 24 cases (18 cases of stage I and 6 cases of stage IV)of advanced ovarian cancer treated with intraperitoneal injection of cisplatin in combination with cytoreductive operation and other chemotherapy. The follow-up observation indicates that the complete response rate and partial response rate is 58% and 25% respectively,making up a total effective rate of 83%.

Objective To study the pathogenesis of pathogens of sexually transmitted disease (STD) in acute pelvic inflammatory disease (PID) Methods Neisseria gonorrhoeae, chlamydia trchomatis, ureaplasma urealyticum were cutured respectively in 130 patients with acute PID Results The pathogens of STD had been found in 55 patients The detective rate of Neisseria gonorrhoeae was 6 9% (9/130), about half of them were mixed infection; the detective rate of chlamydia trachomatis was 4 6% (6/130), all of them were mixed infection; the positive percentage of ureaplasma urealyticum was 37 7% (49/130), one third of them were mixed infection Conclusion The pathogens of STD might cause acute PID or only play a synergetic role in it

Objective:To explore CT and MRI features of the endolymphatic sac tumor (ELST).Methods:The CT and MRI morphology confirmed by surgical pathology for 19 patients with ELST were retrospectively analyzed from June 2011 to May 2019 in Eye & ENT Hospital of Fudan University. The features of CT and MRI included location, size, adjacent structures invasion, CT values, bone destruction, features of T 1WI and T 2WI, enhancement distribution characteristics, dynamic enhancement curve morphology, DWI signal characteristics. The ADC values of the lesions and ipsilateral medial pterygoid muscles were compared using a paired t test. Results:Nineteen ELST patients (one with bilateral diseases) were included. Totally 20 ears (right 9 and left 11) of 13 females and 6 males were studied. The masses with slightly high-density and obscure boundary were located around the vestibular aqueduct at the posterior edge of the petrosal bone. Bone destruction involved mastoid process of the middle ear (16 ears), jugular foramen (11 ears), semicircular canal (10 ears), facial nerve canal (7 ears) and internal auditory canal (9 ears). A large amount of residual bone could be found in the interior of nineteen masses. The CT value was (78.6±21.9) HU. The lesion showed central iso-intensity and peripheral hyperintensity on T 1WI and T 2WI in 16 ears, while no obvious hyperintensity on T 1WI in the other 4 ears. The hyperintensity on T 1WI was around the margin of the lesion in 10 ears, situated at lateral side in 5 ears and all over the lesion in 1 ear. Flow voids signals could be seen in 9 ears as well. Liquid-liquid plane was seen on T 2WI in 2 ears. The solid mass portion which showed iso-intensity on both T 1WI and T 2WI presented marked enhancement on contrast-enhanced T 1WI, while other part of the mass no enhancement. DWI of 14 ears illustrates no evidence of restricted diffusion, and the ADC value [(1.25±0.08)×10 -3 mm 2/s] was slightly higher than that of the medial pterygoid muscles ( t=4.437, P=0.001). The style of time-signal intensity curves of the dynamic contrast-enhanced MRI was rapidly ascending followed by descending curves in 2 ears. Conclusion:Imaging findings of ELST have some characteristics, including located around the vestibular aqueduct at the posterior edge of the petrosal bone, bone destruction, peripheral hyperintensity on T 1WI and no restricted diffusion, which is helpful for its diagnosis.

Objective To evaluate the value of HRCT with multi-planar reformation (MPR) in the diagnosis of otosclerosis.Methods 138 ears in 129 patients with otosclerosis confirmed by surgery were evaluated retrospectively, using the MPR image along stapes as standard image, and 132 normal ears were collected as the control group.Results In the otosclerosis group, HRCT-MPR was positive in 108 ears, suspicious positive in 12 ears, and negative in 18 ears.In the control group, HRCT-MPR was positive in 4 ears,suspicious positive in 9 ears,and negative in 119 ears.The sensitivity for HRCT-MPR was 87.0％ and the specificity was 90.2％.However,with 2 mm axial CT alone ,the sensitivity was only 47.8％.The positive findings were mainly fenestral foci which related to stapes.Conclusions HRCT-MPR showed high rate of sensitivity and specificity.We recommend the MPR image along stapes as standard image for otosclerosis diagnosis.
