Objective To evaluate the effectiveness of GnRH antagonist on vitro fertilization-embryo transfer (IVF-ET). Methods We searched CBMdisc (1979 to 2010), Wanfang (1994 to 2010), CNKI (1994 to 2010), VIP (1989 to 2010), PubMed (1997 to 2010), PML (1997 to 2010), FMJS (2000-2010), and 9 related journals to identify randomized controlled trials (RCTs) on the comparison between GnRH antagonist (GnRHA) and GnRH agonist (GnRHa). The quality of included trials was critically appraised. RevMan 4.2.7 software was used for statistical analysis. Results Six published RCTs involving 1 208 participants were included. Compared with the GnRHa group, stimulation duration in the GnRHA group was lower (WMD= –1.07, 95%CI –1.38 to –0.76), dose of gonadotrophins (Gns) in the GnRHA group was slightly lower (WMD= –0.49, 95%CI –1.63 to 0.66), endometrial thickness at the time of HCG administration was no significant difference in the two groups (WMD= –0.09, 95%CI –0.42 to 0.24), number of oocytes retrieved in the GnRHA group was lower (WMD= –1.80, 95%CI –2.48 to –1.12), OHSS rate in the GnRHA group was slightly lower (Peto OR= 0.77, 95%CI 0.35 to 1.72), pregnancy rate in the GnRHA group was slightly lower (Peto OR= 0.83, 95%CI 0.65 to 1.05), miscarraige rate as no significant difference in the two groups (Peto OR= 1.49, 95%CI 0.79 to 2.82). Conclusions Compared with GnRHa, GnRHA requires shorter stimulation duration and less Gn, less affected the pregnancy rate, and reduces the incidence of OHSS. The use of GnRHA in clinical practice is relatively flexible with good acceptability. GnRHA for the superovulation IVF-ET offers an alternative treatment. The above conclusion still needs more well-designed, multi-center, and large-scale RCTs to confirm and update.
ObjectiveTo analysis the situation of health management service project for patients with hypertension in basic public health service project of Sichuan province from 2015 to 2016, and to provide enhancing suggestions for community prevention of hypertension.MethodsA total of 42 health clinics or community health service centers, 21 counties and 21 cities were extracted each year by method of multistage stratified random sampling from 2015 to 2016. In each institution, we sampled 10 residents, health records of hypertension. Telephone survey was used to judge the accuracy and standard ability of services the patients received according to the national basic public health service specifications, such as personal information, physical examing records, follow up information.The blood pressure of the last follow-up was recorded.ResultsRate of the managed hypertension was from 42.09% to 40.31% (χ2=115.33, P<0.05), rate of the records with accurate information was from 84.29% to 88.79% (χ2=1.94, P=0.16), and rate of the patients received normative services was from 69.49% to 72.33% (χ2=0.54, P=0.57). The control rate of blood pressure was from 82.66% to 85.37% (χ2=0.52, P=0.48). The standardization of the service could obviously improve blood pressure control rates (χ2=22.61, P<0.05).ConclusionProgress has been achieved in health management service of hypertension in Sichuan province from 2015 to 2016, however the standardization of the service is needed to be further enhanced.
Objective To evaluate the effectiveness and safety of intraluminal brachytherapy (ILBT) in prolonging survival and the period free of symptoms for patients with unresectable bile duct cancer. Methods We searched MEDLINE (1977 to May 2007), CNKI (1979 to May 2007) and CBM Disk (1979 to May 2007). The qual ity of included studies was assessed according to the guidance in the Cochrane Handbook for Systematic Reviews of Interventions. Results One randomized controlled trial involving 42 patients with unresectable bile duct cancer fulfilled the inclusion criteria. This found that the median survival time was longer for patients treated with endoprostheses and ILBT compared to those treated with endoprostheses alone (387.9 days versus 298.0 days, Plt;0.05). The stent patency time in patients who were treated with endoprostheses and ILBT was longer than for those treated with endoprostheses alone (378.4 days versus 245.5 days, Plt;0.01). The reductions in bil irubin (mol/l) and alkal ine phosphatase (kat/l) before and after drainage in patients who were treated with endoprostheses and ILBT were similar to those treated with endoprostheses alone (Mean ±SD of bil irubin: before: 219.3 ± 40.5, after: 23.1 ± 37.1 versus before: 227.3 ± 39.8, after: 22.5 ± 44.2; Mean ± SD of alkal ine phosphatase: before: 10.3 ± 5.1. after: 3.6 ± 2.9 versus before: 11.7 ± 5.8, after: 3.7 ± 2.9). No severe adverse effects were observed in the trial. Conclusion Current evidence suggests that ILBT for unresectable bile duct cancer may improve the survival time of patients, prolong the time they spend symptom free, improve their quality of l ife and reduce the burden of treatment. However, it may increase toxicity in normal tissues, which can be managed by adjusting radiation dosage. No serious adverse effects were observed in the 42 patients in the trial in this review. More randomized controlled trials with large sample size are needed to provide rel iable results.
Objective To explore the application of peer education in TB prevention at middle schools in Kai County of Chongqing and compare it with traditional education, and to provide theory support for further policy making. Methods Four complete middle schools were randomly selected as the control group, the peer education group, the traditional education group and the combined group of peer education and traditional education, respectively. Effect evaluation was performed one month later (instant evaluation) and six months later (long-term evaluation), respectively, after the intervention period. Results The instant and long-term evaluation showed that the knowledge, attitude and practice scores of the three intervention groups were higher than the scores before intervention or those of the control group (Plt;0.01). Besides, the behavior score of the peer education group had no significant difference between instant and longterm evaluation. All scores in the instant evaluation were higher than those of long-term evaluation both in the peer education group and the traditional education group (Plt;0.01). For the knowledge, attitude and practice scores, there was no significant difference between instant and long-term evaluation in the combined group of peer education and traditional education. Conclusion Compared with the peer education group and the traditional education group, the combined group achieves an enduring effect. There is obvious instant effect in the traditional education group, and peer education has a long-term influence on students’ behavior.
Objective
To establish a method to isolate the CD4+CD25+ regulatory T cells (Tregs) and to identify the purity and function of these cells.
Methods
The peripheral blood (8 mL) were collected from the great saphenous vein of 10 rhesus monkeys (4 females and 6 males, aged 4-5 years, and weighing 5-8 kg). The mononuclear cells were isolated with density gradient centrifugation. CD4+ T cells were separated by the Magnetic cell sorting (MACS) negative selection and MACS positive selection. The cell yield rate, the cell viability, and the cell purity were compared between MACS negative selection and MACS positive selection. In CD4+ MACS negative selection, the anti-biotin MicroBeads and biotin-antibody cocktai in CD4+CD25+ Tregs isolation kit non-human primate were used, and in MACS positive selection, the anti-APC MicroBeads in CD4+CD25+ Tregs isolation kit non-human primate and CD4-APC were used. The CD4+ T cells separated by positive selection were selected to obtain CD4+CD25 Tregs with CD25 MicroBeads. The purity, activity, the FoxP3 level, and the suppressive function to concanavalin A (ConA) activated autologous CD4+CD24- effective T cells (Teffs) of CD4+CD25+ Tregs were detected by flow cytometry.
Results
After CD4+ T cells were separated by MACS negative selection and MACS positive selection, the cell viabilities were all up to 95%, showing no significant difference (P gt; 0.05). The cell yield rate and purity of CD4+ T cells by positive selection were significantly higher than those of CD4+ T cells by negative selection (P lt; 0.05). CD4+CD25+ Tregs can be successfully isolated by MACS double positive selection. The classifying purity was 76.2% ± 8.6%; the cell activity was 93.3% ± 4.7%; and the level of FoxP3 was 74.2% ± 6.9%. The CD4+CD25+ Tregs had suppressive effect on ConA activated autologous CD4+CD25- Teffs.
Conclusion
MACS double positive selection can be used to isolate high-purity CD4+CD25+ Tregs from the peripheral blood of rhesus monkeys and the process does not influence the activity of CD4+CD25+ Tregs.
ObjectiveTo compare the efficacy of subtotal parathyroidectomy(sPTX) and total parathyroidectomy (tPTX) plus parathyroid autotransplantation(AT) in treatment of secondary hyperparathyroidism(SHPT).
MethodsClinical data of 76 cases of uremia SHPT who underwent sPTX(n=19) and tPTX+AT(n=57) in Xinjiang Armed Police Corps Command Military Hospital and The Xinjiang Uygur Autonomous Region People's Hospital were retrospectively analyzed(from Feb. 2005 to Sep. 2012).
ResultsOf the 76 cases, 68 cases(89.5%) got successful surgery and 8 cases (10.5%) suffered non-complete resection, all cases had relief on bone pain, and 14 cases had relief on pruritus(26.9%, 14/52). The values of serum calcium on 1 day, 7 days, and 6 months after operation were lower in tPTX+AT group (P<0.05), and value of iPTH in 6 months after operation was lower too(P<0.05). The operation time, blood loss, hospital stay, and hospital cost in tPTX+AT group were all higher or longer(P<0.05). All of the 76 cases were followed up for 6-18 months(the median time was 8.7 months). During the followed-up, 2 cases died and 2 cases recurred in tPTX+AT group, 1 case died and 7 cases recurred in sPTX group, that the recurrence rate was higher in sPTX group (P<0.05).
ConclusiontPTX+AT has lower recurrence rate, but with longer operation time and hospital stay, more blood loss, and expensive cost, so the choice of surgery for SHPT should be based on the comprehensive situation.
ObjectiveTo investigate the operation and effect of pressure ulcers group (PUG) on the procedure of clinical management of pressure ulcers.
MethodsThe in-hospital patients with high-risk pressure ulcers and patients with pressure ulcers from outside of the hospital (n=145) before the founding of PUG in 2011 were regarded as group A, and patients in this group were treated by traditional therapies. After PUG was founded in our hospital in January 2012, 192 patients with high-risk pressure ulcers and from outside of the hospital in 2012 were considered as group B. In addition, group C contained 380 patients treated in 2013. Group B and C were both treated by PUG that developed a management system of pressure ulcers and took active measures to control and prevent pressure ulcers. PUG trained 30 clinical nurse supervisors, who were recommended from relevant clinical departments. The incidence of inevitable pressure ulcer of hospitalized patients, the cure rate of patients with pressure ulcers from outside of the hospital, pressure ulcer knowledge level of clinical nurse supervisors were comparatively analyzed between group A and B, and between group A and C, respectively.
ResultsAfter the establishment of PUG, the incidence of inevitable pressure ulcer of hospitalized patients in group A, B, and C was 76.20%, 17.02%, and 14.61%, respectively. The cure rate of patients from outside of the hospital was 54.84%, 86.84%, and 87.97%, respectively. Differences between group A and B, and between group A and C both were significant (P<0.01). The pressure ulcer knowledge level of all nurse supervisors improved significantly (P<0.001).
ConclusionThe establishment of PUG makes the clinical pressure ulcer management more scientific and objective. Furthermore, it can effectively reduce the incidence of pressure ulcers, and also improve the quality of medical care and ensure the safety of patients.
Abstract: Objective To investigate the method of improving effect, by investigating and analyzing the possible risk factors affecting shortterm outcome after total correction of tetralogy of Fallot (TOF). Methods Data of 219 patients who received total correction of TOF were divided into two groups according to the length of postoperative stay in hospital and recovery of heart function in the near future. Group A(n=110): patients had good recovery of heart function classified as gradeⅠorⅡ（NYHA classification）, and could smoothly be discharged from the hospital within two weeks without serious complications. The left ventricular ejection fraction (LVEF) had to exceed to 0.50 during 6 months followup visit. Group B(n=109): patients had worse recovery of heart function classified as grade Ⅱ or Ⅲ, and could not be discharged within two weeks with severe complications. LVEF was less than 0.50 during 6 months followup visit. The clinical data of two groups were compared, and risk factors affecting shortterm outcome after total correction of TOF operation were analyzed by logistic regression and model selection. Results There were good recovery of heart function classified as gradeⅠorⅡ(NYHA classification）in discharge, no death, and LVEF all exceeded to 0.50 in group A; there were 8 deaths in group B (7.34 %), and recovery of heart function was worse classified as grade Ⅱ or Ⅲ, with LVEF being less than 0.50（Plt;0.01）. Amount of postoperative daily thoracic drainage, assisted respiration time, time of inotropic agent stabilizing circulation, and the average length of postoperative stay in group A were all less or short than those in group B（Plt;0.01）. But the bypass and clamping time of group B were exceeded group A. The ratio of patching astride annulus in group B was greater than that in group A, and Nakata index was less than that in group A(Plt;0.01). The results of logistic regression and model selection indicate: age at repair (OR=0.69), oxygen saturation(OR=0.98), haematocrit before operation (OR=0.94), and patching astride annulus (OR=46.86), Nakata index (OR=16.90), amount of postoperative daily thoracic drainage (OR=0.84), presence of arrhythmia(OR=0.87), and wound infection(OR=63.57) have significant effect with shortterm outcome after total correction of TOF operation. Conclusions The probable methods to improving effect of shortterm outcome after total correction of TOF are an earlier age at repair, decreasing haematocrit, rising oxygen saturation before surgery, performing a palliative operation facilitating development of arteriae pulmonalis in earlier time, improving the surgical technique, and strengthening the perioperative care.
Objectives To evaluate the effectiveness of different antidepressant drugs in addition to standard clinical care in the prevention of postnatal depression. To compare the effectiveness of different antidepressant drugs and with any other form of intervention for postnatal depression i.e. hormonal, psychological or social support. To assess any adverse effects of antidepressant drugs in either the mother or the foetus/infant.Methods The register of clinical trials maintained and updated by the Cochrane Depression, Anxiety and Neurosis Group and the Cochrane Pregnancy and Childbirth Group.Randomised studies of antidepressants alone or in combination with another treatment, compared with placebo or a psychosocial intervention in non-depressed pregnant women or women who had given birth in the previous six weeks (i.e. women at risk of postnatal depression). Data were extracted independently from the trial reports by the authors.Missing information was requested from investigators wherever possible. Data were sought to allow an intention to treat analysis.Results Two trials fullled the inclusion criteria for this review. Both looked at women with a past history of postpartum depression.Nortriptyline (n=26) did not show any benefit over placebo (n=25). Sertraline (n=14) reduced the recurrence of postnatal depression and the time to recurrence when compared with placebo (n=8). Intention to treat analyses were not carried out in either trial.Conclusions It is not possible to draw any clear conclusions about the effectiveness of antidepressants given immediately postpartum in preventing postnatal depression and, therefore, cannot be recommended for prophylaxis of postnatal depression, due to the lack of clear evidence. Larger trials are needed which also include comparisons of antidepressant drugs with other prophylactic treatments to reect clinical practice, and examine adverse effects for the foetus and infant, as well as assess womens’ attitudes to the use of antidepressants at this time.
