ABSTRACT
Objective To observe the clinical effects of preoperative intranasal dexmedetomidine in pediatric anesthesia.Methods From April 2014 to April 2017,40 pediatric patients who accepted elective circumcision,ASA Ⅰ,aged 2 to 10 years in Wenjiang Branch of Sichan Provincial People's Hospital were divided into two groups,with 20 cases in each group.The test group received intranasal dexmedetomidine 1 μg/kg,and the control group received intranasal equal volume of saline 30 min before surgery.HR,SpO2,BP were monitored and recorded before intranasal (T0),5min after intranasal (T1),10min after intranasal (T2),20min after intranasal (T3),30min after intranasal (T4).The sedation score was assessed after 30 min of administration.The restless score was observed after waking.Results ANOVA analysis showed that there were significant differences in SBP (F =14.54,P ＜ 0.05) and DBP (F =22.69,P ＜ 0.05) between the two groups,and the SBP (F =13.77,P ＜ 0.05),DBP (F =10.48,P ＜ 0.05),HR(F =5.13,P ＜ 0.05) had interaction effects.Compared with those of the control group,the heart rate and the diastolic pressure of the test group were decreased at T2 ～ T4 (all P ＜ 0.05).The sedation score of the test group was superior than that of the control group(t =-9.131,P ＜0.05),and the postoperative agitation score was lower than that of the control group (t =3.387,P ＜ 0.05).Conclusion Intranasal dexmedetomidine can provide satisfactory sedative effects without affecting the vital signs of children and significantly reducing the postoperative agitation.
ABSTRACT
Objective To explore the emergency PCI symptom-onset-to-balloon time (SOTBT) influence on the local cardial function in patients with acute ST-segment elevation myocardial infarction (STEMI) by two-dimensional speckle tracking imaging (2D-STI) technology.Methods Sixty cases were ifrst diagnosed with ST-elevation myocardial infarction (STEMI) and undergone emergency PCI surgery in Huangshi central hospital from June 2014 to June 2016. According to SOTBT, patients were divided into two groups: SOTBT≤6h myocardial infarction group, 6 h
ABSTRACT
Objective To study the efficacy of performing transvaginal Prosima mesh with high uterosacral ligament suspension (HUS) in treatment of severe pelvic organ prolapse (POP).Methods From July 2010 to February 2011,70 patients with severe POP underwent transvaginal prosima mesh with HUS in First Affiliated Hospital,General Hospital of People's Liberation Army.Clinical parameters of perioperation were collected.After 1 month and 2 - 3 months,perineal two-dimensional ultrasound examination was performed to measure mesh length in midsagittal plane.Validated prolapse quality of life questionnaires,pelvic floor distress inventsry short form 20 (PFDI-20) and pelvic floor impact questionnaire short form 7 (PFIQ-7) were used to evaluate the therapeutic effect.The mean results of pre-operative PFIQ-7 and PFDI-20 was 54 and 51,respectively.Results Median operation time was ( 195 ± 47 ) min and median blood loss was (160 ±64) ml.All the patients were followed for a mean time of 13 months (2 - 19 months).Seven cases were found with mesh exposure with less than 1 cm2.The objective cure rate was 100％.The mean score of post-operative PFIQ-7 and PFDI-20 were both 19,which were significantly lower than those of preoperation ( P ＜ 0.05 ).Anterior Prosima mesh was 3.5 cm at 1 month by ultrasound examination,and the second result of ultrasound scans was 2.8 cm at 2 - 3 month,which were both shortened 2.5 cm and 3.2 cm when compared with that of original size.Conclusions Transvaginal Prosima mesh placement with HUS is a safe and efficient surgery with less complication.Although mesh became shorter after 2 - 3 month,it did not affect surgery efficacy.
ABSTRACT
This study is to explore the effects of quercetin (QUE) on the 3 week-old mice ovarian development and relative hormone levels. The 3 week-old mice were exposed to QUE (45, 25, and 5 mg x kg(-1) x hd(-1)) by gavage for 50 days. The estrous cycle during 50 days and the changes of hormone level such as FSH, LH, etc were monitored. Moreover, the ovaries were removed after sacrifice. The organ index was measured, and the ratios of different stages of follicles were analyzed by HE staining. Furthermore, the proportion of PCNA positive cells during all stages was detected by immunohistochemistry. The results showed that QUE could increase body weight of mice and reduce the anogenital distance (AGD) to some extent, and was able to disrupt mice's estrous cycle, but it could not extend or reduce the cycle regularity. It increased ovarian organ index with a dose-dependent manner. The proportion of the primordial follicle and secondary follicles rose obviously, and that of mature follicles', atretic follicles' and corpus luteums' reduced, while primordial follicle had no change. Immunohistochemistry analysis showed that QUE could effectively increase the percentage of proliferating cells in all kinds of follicles. Serum hormone assay showed that there were significant changes of FSH and LH levels. In summary, QUE showed an estrogen-like effect on mice's ovarian development. The weight of ovary, the proportion of all kinds of follicles, the development of ovarian cells and the level of plasma hormone in mice were altered obviously by oral administration of QUE.
ABSTRACT
AIM: To observe the clinical efficacy of Dengzhan Shengmai Capsules(Herba Erigerontis,Radix et Rhizoma Ginseng,Radix Ophiopogouis,Fructus Schisandrae chinensis) in improving type 2 diabetes insulin resistance. METHODS: 98 patients were randomly divided into two groups: the control group(50 cases) were treated with conventional therapy,the treatment group(48 cases) were treated with Dengzhan Shengmai Capsules based on conventional therapy.These two groups were all treated for 2 months.FPG,FINS,2hPG,HbA_1C and ISI were observed before and after treatment. RESULTS: The total effects of the treatment group(91.67%) was higher than that of the control group(40.00%)(P
