Objective To compare the therapeutic effect of two Methodsof in vitro oocyte maturation (IVM) technology with polycystic ovary syndrome (PCOS) patients in infertility treatment.MethodsRetrospective analysis was performed on patients with PCOS infertility who were stimulated with two different kinds of stimulating method of the IVM cycle in our center during April 2010 and August 2010.There were 20 patients in the temporary FSH stimulating group (group A) and 31 patients in the HCG stimulating group (group B).The number of oocytes maturation rate,fertilization rate,cleavage rate,excellent embryo rate,implantation rate,pregnancy rate per oocyte recycle,pregnancy rate per transfer and abortion rate of transfer were compared.ResultsThere was no significant difference between the two groups of age,duration of infertility,body mass index,based sex hormone levels by t test(P＞0.05).There was no significant difference between the two groups of the number of oocytes retrieved,oocyte maturation rate,cleavage rate,and abortion rate of transfer(P＞0.05).In group B,the fertilization rate was 80.3%,good-quality-embryo rate was 49.8%,implantation rate was 31.5%,pregnancy rate per oocyte recycle was 54.8%,which was significantly higher than in group A (73.9%,35.4%,12.5% and 25.0%,respectively).ConclusionsIf IVM was used to treat PCOS patients with infertility,HCG stimulating will be better than FSH stimulating,and it could result in a higher clinical pregnancy rate.

Objective To explore the effect of meditation training on postoperative pain, anxiety and reduce the incidence of constipation in patients with lower limb fracture. Methods The enrolled 106 patients with lower extremity fractures were randomly divided into the observation group and control group 53 cases respectively according to the odd even method. The control group was implemented with fracture surgery routine care, while the observation group was implemented with meditation training on the basis of the control group, the two groups were compared by postoperative pain score, anxiety, constipation, and satisfaction. Results Before intervention, the postoperative pain Visual Analogue Scale (VAS) scores and anxiety scores of the two groups were not significantly different (P>0.05). After intervention, the postoperative pain scores of observation group and control group were (2.06 ± 0.85) points and (4.15 ± 0.62) points respectively, the difference was statistically significant (t = 4.103, P <0.05). The anxiety scores of observation group and control group were (28.95 ± 3.83) points and (56.13 ± 3.52) points respectively, the difference was statistically significant (t= 2.353, P < 0.05). The first defecation time and the cases number of observation group patients were as follows:day 1st:20.75%(11/53), day 2nd: 52.83% (28/53), day 3rd: 18.87% (10/53), day 4th: 7.55% (4/53). While the data of the control group were day 1st: 1.89% (1/53), day 2nd: 26.42% (14/53), day 3rd 37.74% (20/53), day 4th:33.96%(18/53), the difference between the two groups was statistically significant (χ2=4.022-5.629, P<0.05). The satisfaction of observation group and control group patients were 94.34%(50/53), 77.36%(41/53) respectively, the difference was statistically significant (χ2=4.543, P < 0.05). Conclusions Meditation training can effectively reduce postoperative pain, reduce the incidence of anxiety and constipation, and improve the satisfaction of patients to nursing service, and promote the recovery of patients after surgery.

Academic diligence level can not only directly affect the academic performance of students, but also affect the individual's emotional and physical health. In this study, through a question-naire survey of university students, with the method of SIMPP and the concept of the micro system engi-neering in higher education teaching reform, the related factors of diligence and the college students' behavior mode with respect to diligence are systematically analyzed. Analysis shows that, students' diligence level is affected not only by inherent factors such as clear learning objectives, learning state and after-school learning time, but also by the school ethos, the influence factors of the curriculum and parents' re-quirements.

Objective To evaluate the effects of perioperative rehabilitation for patients with self-forearm internal arteriovenous fistula.Methods Divided 124 patients with end-stage renal disease into the functional training group (65 cases,A group)and the control group(59 cases,B group) randomly,and then compared certain related indexes between the two groups.Results In the A group,the artery diametcr was obvious widen before functional training without operation,and the vein diameter was obvious widen before functional training without operation too,P ＜ 0.05.After operation,the A group Anastomotic unobstructed was obviously better than B group in one-stage,P ＜ 0.05.A group with thrombosis cases significantly less postoperative than B group,P ＜ 0.05.A group with edema of hands was significantly shorter than B group,P ＜ 0.01.Postoperative fistula time to maturity in the A group was (43.76 ± 2.21) days,which was significantly shorter than that of in the B group,(49.69 ± 5.85) days,P ＜ 0.01.Conclusion Systematic strengthening of perioperative functional exercises can significantly improve preoperative vascular conditions,improve the success rate of operation,reduce risk of thrombosis cases,shorten the time of hand edema and the time of fistula in mature.

Objective To study the influence of Compound Salvia injection combined with cefoperazone sulbactam sodium on renal function and renal interstitial fibrosis in elderly patients with chronic pyelonephritis (CPN).Methods From April 2013 to July 2014, 126 cases of CPN were divided into observation group ( n =63 ) and control group ( n =63 ) according to the order of admission to hospital.All patients were given cefoperazone sulbactam sodium, and patients in observation group were added Compound Salvia injection.The clinical efficacy of treatment were evaluated between two groups, renal function and TGF-β1 were observed and compared before and after treatment in two groups.Results After treatment, HE staining of nephridial tissue showed renal interstitial fibrosis in observation group obvious improved more.The overall response rate of observation patients (90.48%) was significantly higher (74.60%) than control group, and the relapse rate of observation group (1.59%) was significantly lower than control group (14.29%), and there were statistically significant differences (P<0.05).After treatment, urinary albumin (11.4 ±3.1) mg/L, BUN (5.7 ±0.5) mmol/L, and Scr (103.2 ±10.4)μmol/L of observation group were significantly lower than control group, respectively (P<0.05).After treatment, TGF-β1 level (103.4 ±32.5) ng/L of observation group was significantly lower than control group (202.4 ±35.2) ng/L(P<0.05).There was no significant difference in adverse reactions between two groups.Conclusions Compound Salvia injection combined with cefoperazone sulbactam sodium has good efficacy.can significantly improve renal function, delay renal interstitial fibrosis in treatment of elderly patients with chronic pyelonephritis.

Objective:To explore the investigation level of individual monitoring for medical radiation workers.Methods:Monitoring and analysis of individual doses to the medical radiation workers in Guangdong province were performed, from 2016 to 2019, by the Individual Dose Monitoring Department of Guangdong Provincial Hospital for Occupational Disease Prevention and Control.Results:The numbers of monitored workers were diagnostic radiology 53 674, dental radiology 2 563, nuclear medicine 5 001, radiotherapy 16 687, interventional radiology 22 272 and others 2 087 from 2016 to 2019, of which the number of individuals with doses in excess of investigation level 1.25 mSv, were 76, 6, 18, 28, 133 and 2 respectively. The non-real doses made up 67.1 %, 100 %, 55.6 %, 82.1 %, 76.7 % and 100 % of their respective totals. Their 99th percentile doses P99 were 0.37, 0.39, 0.67, 0.35, 0.54 and 0.30 mSv, and the average periodic dose equivalent were 0.07, 0.06, 0.11, 0.06, 0.07 and 0.05 mSv respectively, indicating a statistically significant difference existing in the average annual effective dose between groups ( Z=-26.139--2.681, P<0.001). Conclusions:Due to non-reality of doses in excess of investigation levels and high labor cost, it is suggested to currently use 0.40 mSv per 3 months as investigation level for diagnostic radiology, dental radiology, radiotherapy and others, and 0.70 mSv per 3 months as for nuclear medicine and interventional radiology.
