Chinese Journal of Perinatal Medicine 2011;14(9):540-544
Objective To investigate the possibility of reserving uterus during severe postpartum hemorrhage. MethodsA retrospective analysis was conducted on the clinical data of 138 cases of severe postpartum hemorrhage (blood loss ≥2000 ml) from January 1, 2003 to December 31, 2009. Results Among 138 cases of severe postpartum hemorrhage, uterine atony (n= 60, 43. 38 % ) was the first cause and the second was placental factor (n= 55, 39.86 %). The blood loss varied from 2000 ml to 10 000 ml and the mean level was about (3004± 1473) ml. The volume of blood transfusion for these patients varied from 800 ml to 7200 ml. Among these patients, the blood loss of 108 cases reserved uteri was from 2000 ml to 7500 ml, with the average of (2564±932) ml; while for 30 cases performed with hysterectomy, the blood loss was about 2500 to 10 000 ml averagly (4653± 1857) ml (t=8. 57, P=0.00). These patients were divided into two groups according to time series. Twelve cases of hysterectomy were performed during 2003to 2005, and the hysterectomy rate was 0. 47‰; 18 cases of hysterectomy were performed during 2006 to 2009, and the hysterectomy rate was 0. 36‰. The average blood loss of the above two groups was (3783±861) ml and (5233±2124) ml respectively (t=2. 234, P=0. 034). Among all the cases with blood loss ≥ 3000 ml, uteri were reserved in 24 cases with the average blood loss of (3818 ± 1284) ml; while hysterectomy were performed in 27 cases with average blood loss of (4900 ± 1789) rnl (t = 2. 453, P =0. 018). The time for blood loss to 3000 ml in the two groups was (160±129) min and (100±67) min,respectively, and the difference was significant (t=2. 113, P = 0.04).The uteri of six cases with postpartum hemorrhage over 4000 ml were successfully reserved, and average bleeding amount was 5570 ml.Two patients among the 138 women died of amniotic fluid embolism.The perinatal mortality rate was 3. 73%.ConclusionsThe postpartum hemorrhage volume and velocity is the key point to decide whether to reserve the uterus or not.For the population with high risk factors,prophylaxis treatment with prostaglandins should be initiated to reduce the bleeding volume.Uterine packing might be an effective treatment to stop postpartum hemorrhage, especially for those bleeding due to placenta previa.

Conclusion The of BudesonideNasal Spray puls Gelomyrtol Forte is better than that of Cefaclor Dispersible Tablets for acute secretory otitis media. The mild adverse reaction is the same between the two groups.

World Science and Technology-Modernization of Traditional Chinese Medicine 2013;(7):1581-1586
This study was aimed to reveal the effector mechanisms of Chinese medicine aconite, ginseng, astragalus and dried ginger on the intervention of adriamycin (ADR) cardiotoxicity model rats. The analysis was made on the interactive relationship between aconite and ginseng, astragalus as well as dried ginger. A total of 72 rats were randomly divided into nine groups. There were eight rats in each group. Except the normal group, rats in each group were intraperitoneally injected with 2.5 mg·kg-1 of ADR according to their body weights. The injection was given once a week and continued for four weeks. The total dosage was 10 mg·kg-1. In the aconite, dried ginger group, the intragastric administration dosage of herbal decoction was 1.75 g·kg-1. The decoction dosage in the gin-seng, astragalus group was 0.875 g·kg-1. The decoction dosage in the Shenfu, Qifu group was 2.625 g·kg-1. The decoction dosage in the Jiangfu group was 3.5 g·kg-1. The intragastric administration was given once a day and continued for four weeks. Indexes such as superoxide dismutase (SOD), cardiac troponins (cTn), cytochrome C (CytC), myocardial mitochondria of Bax, Bcl 2, caspase-3, caspase-9 were detected. The colligation score was calculated associating with the close index. One-way ANOVA was given on different indexes and colligation indi-cators among different drug groups and the factorial design variance analysis was given to reveal the drug interac-tions. The results showed that compared with the normal group there were statistical significances among different indexes in the model group (P < 0.05). Aconite, ginseng, astragalus, dried ginger had varying degrees of impact on different indicators. There were statistical significances on the interaction between aconite and ginseng, astra-galus, dried ginger (except Bax). It was concluded that herbal medicine aconite, ginseng, astragalus, dried ginger had certain protective effect to the heart of ADR model rats. The combination of aconite and ginseng, astragalus, dried ginger can enhance the effect compared with a single herb.

International Eye Science 2015;(4):654-655
AIM: To investigate the clinical effects of phacoemulsification and surgical techeniques in small pupil cataract after filtering operation of glaucoma.
METHODS: Thirty-six cases ( 36 eyes ) of small pupil cataract after filtering operation of glaucoma were underwent phacoemulsification combined with foldable intraocular lens implantation. Postoperative visual acuity, intraocular pressure filtration bleb and complications were observed. The follow-up time was 3mo.
RESULTS: The preoperative uncorrected visual acuity (UCVA) or best-corrected visual acuity ( BCVA) ≤0. 3 were in all patients. Postoperativerly, the UCVA or BCVA≥0. 3 after 1wk and 3mo were achieved in 23 eyes (63.89%) and 34 eyes (94. 44%). BCVA was <0. 3 in 2 eyes ( 5. 56%) including optic nerve atrophy of one eye and diabetic retinopathy of one eye. All patients were kept the level of normal intraocular pressure and completed filtering bleb, there were no serious complications.
CONCLUSION: Phacoemulsification in small pupil cataract after filtering operation of glaucoma was complex, and reasonable application of operation skills can still achieve better clinical results. The main factor of affecting the visual acuity is pre-existing retinal optic neuropathy.
