Objective To investigate the clinical manifestations,pathological features,treatment and prognosis of nongesta-tional choriocarcinomas.Methods The clinicopathological data in 4 cases of nongestational choriocarcinoma were retrospectively analyzed and the relevant literatures were reviewed.Results All 4 patients had no confirmed diagnosis at first visit to hospital.All patients received the operative therapy and postoperative bleomycin,etoposide and cis-platinum (BEP)regimen chemotherapy.The followed up lasted for 3-32 months.One case died at postoperative 26 months due to pulmonary metastasis;one case was loss of follow up;two cases had relatively favorable condition.Conclusion Nongestational choriocarcinoma is a rare and highly invasive trophoblastic neoplasm,and is prone for early distant metastasis.The treatment is recommended to adopt operation combined with postoperative combined chemotherapy of multiple drugs.

Objective To observe the short-term visual effects of cataract surgery patients with 1CU accommodating intraocular lens (IOL) compared with aspheric monofocal IOL. Design Non-randomed comparative trial. Participants Consecutively 118 senile cataract patients (118 eyes). Methods 59 cataract patients (59 eyes) were implanted 1CU accommodating IOL (1CU group), and 59 cataract patients (59 eyes) were implanted aspheric monofocal IOL (Tecnis ZA9003 group). All patients were assessed at 3 months post-operation in the aberrations of crystalline, the modulation transfer function contrast sensitivity of 10/100 percent in three sorts distance(40, 63, 100 cm), uncorrected distanced visual acuity(UCDVA), uncorrected near visual acuity(UCNVA), best-corrected distance visual acuity(BCDVA), best-corrected near visual acuity(BCNVA), distance corrected near visual acuity(DCNVA), pseudo-accommodation, and the rate of off-near glasses. Main Outcome Measures Visual acuity, aberrations, modulation transfer function, contrast sensitivity, pseudo-accommodation, the rate of off-near glasses. Results At 3 months postoperatively, both UCNVA and DCNVA were significantly better in 1CU group than in the aspheric monofocal IOL group (t=8.85, P=0.00; t=13.05, P=0.00). The accommodative range was (2.58?0.37) D in 1CU group and (1.46?0.25) D in monofocal IOL group (t=14.33, P=0.00). In 3 mm and 5 mm pupil diameter the difference of the total aberration and spherical aberration in Tecnis ZA9003 group or 1CU group was significant (3 mm pupil t=18.48, P=0.00; t=5.70, P=0.00. 5 mm pupil t=19.98, P=0.00; t=6.70, P=0.00). At 40 cm and 63 cm, VA scores were higher in 1CU group (85%)than in Tecnis ZA9003 group (25%) (t=3.64, P=0.00; t=2.74, P=0.00; t=2.65, P=0.00; t=2.44, P=0.01). The rate of off-near glasses in 1CU group was better than in the aspheric monofocal IOL group(?2=41.95, P=0.00). Conclusions The 1CU accommodating IOL can provide better useful near visual acuity than aspheric monofocal IOL, especially for the patients who want to get rid of spectacles.

Objective To study the early diagnostic value of CT for children with cerebral palsy.Methods CT manifestations of 124 cases with cerebral palsy were analysed retrospectively. Results 96 cases of the 124 cases showed a recognisable abnormality,the abnormal rate of CT was about 77.42％ ,and the most common abnormality was cerebral atrophy.Spastic type was the most common clinical type(71.77％ ).The less of the age,the higher of the abnormal rate of CT. Conclusion Although CT isn't the main basis of the diagnosis of cerebral palsy,it's helpful for us to find the pathological changes,and to find the eliology and location.It also provided basis for us to judge the prognosis of cerebral palsy.So CT has significant value in the early diagnosis of cerebral palsy.

OBJECTIVE:To observe clinical efficacy and safety of nitric oxide (NO) combined with sildenafil in the treatment of neonatal pulmonary hypertension. METHODS:66 cases of neonatal pulmonary hypertension were selected and randomly divided in-to observation group and control group,with 33 cases in each group. 2 groups of patients were given Dopamine injection 5 μg/(kg· min),ivgtt. Control group was given NO 5-20 ppm;observation group received oral or nasal feeding of Citric acid sildenafil tab-lets,0.5-1.0 mg/kg,96 h,on the basis of control group. Both group received 3 d of treatment. Clinical efficacy of 2 groups were observed as well as the level of PaO2,PaCO2,SaO2,PAP,NO,ET-1,HIF-1α,EPO and Ca2+before and after treatment. The inci-dence of ADR was compared between 2 groups. RESULTS:Total effective rate of observation group was 96.97%,which was sig-nificantly higher than that of control group(75.76%),with statistical significance(P<0.05). There was no statistical significance in the levels of PaO2,PaCO2,SaO2,PAP,NO,ET-1,HIF-1α,EPO and Ca2+between 2 groups before treatment(P>0.05);com-pared to before treatment,PaO2,SaO2,No and Ca2+ levels of 2 groups increased significantly after treatment,while PaCO2,PAP, EPO,HIF-1,ET-1 significantly lowered and the observation group was better than the control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Sildenafil combined with NO is effective in the treatment of neonatal pulmonary hypertension and can effectively improve pulmonary hypertension and blood gas indexes with good safety.

We present a case of two-year old boy with solitary atypical adenomatous hyperplasia (AAH) in extralobar sequestration (ELS), which was misdiagnosed as diaphragmatic hernia before surgery. Review of AAH and pulmonary sequestration (PS) revealed that the present case is the youngest of solitary AAH and also the first report of solitary AAH arising in ELS without a primary lung cancer. In a sense, the present case firstly supports the hypothesis that ELS may be an underlying cancer predisposition syndrome, so aggressive surgical therapy should be recommended for ELS.

Objective To investigate the effect of uterine cavity injection of absolute ethanol on estrous cycle in mice.Methods Twenty mice with regular estrous cycle were selected by vaginal exfoliated cells staining, and then were injected absolute ethanol into their uterine cavity.The estrous cycle was observed and recorded every day.Ten mice were selected randomly to observe the changes of second estrous cycle every two hours.Results After the injection of absolute ethanol into the uterine cavity of the experimental mice, the estrous cycle was greatly prolonged, and the various degree of disorder was observed in estrus and pre-estrus.Conclusions The disorder was observed in estrous cycle of mice after the injection of absolute ethanol, which maybe provides some references for clinical use of absolute ethanol.

Objective To explore the changes in fractional anisotropy (FA) among cerebral infarction pa-tients using MR diffusion tensor imaging (DTI), and to verify the relationship between any FA changes and functional recovery. Methods Thirty-eight cerebral infarction patients were divided into two groups according to their recovery level using Brunnstrom's criteria. All the patients accepted routine MR and DTI examination, and FA values were measured during the acute, subacute and chronic stages of their recovery. Results Average FA values in the lesion area were significantly lower than in the corresponding contralateral area, and were highest daring the acute stage.There was no significant difference between the subacute and chronic stages. Conclusions The FA values of cere-bral infarction patients change during the different stages of recovery with a certain regularity. This may be valuable for clinical treatment and prognosis.
