Objective To determine the effect of non-reamed versus reamed intramedullary nailing for tibial fractures in adults on the rates of nonunion, the rates of implant failure, the rates of infection, the incidence of compartment syndrome, the rates of malunion, and the time of union. Methods We searched MEDLINE （1966 -July, 2005）, EMBASE （1974 -July, 2005 ）, The Cochrane Library （Issue 2, 2005 ）and CBMdisc （1979 -July, 2005 ）, and handsearched the relevant Chinese and English orthopedic journals. Randomized controlled trials and Clinical controlled trials of nonreamed versus reamed intramedullary nailing for tibial fractures in adults were included. The quality of trials was critically assessed. RevMan 4.2.7 software was used for data analysis. Results Four RCTs and one CCT of non-reamed versus reamed intramedullary nailing for tibial fractures in adults were included. The results of meta-analysis showed that nonreamed intramedullary nailing for tibial fractures in adult increased the rates of nonunion （RR 1.87, 95% CI 1.20 to 2. 91, P =0. 006）, implant failure （RR 2.23, 95% CI 1.49 to 3.34, P〈0. 000 1 ） and the time to union （WMD 9.00, 95% CI 3.19 to 14.81, P =0. 002）. Conclusions Compared with reamed intramedullary nailing for tibial fractures in adults, non-reamed intramedullary nailing increases the rates of nonunion and implant failure is common. There is no statistical difference in the rates of post operative infection, the rates of malunited fracture and the incidence of compartment syndrome between the two groups. However, further studies are needed to determine the effects of reamed and non-reamed intramedullary nailing on these outcomes, expecially when patient has severe open fractures （Gustilo Grade Ⅲ C）and multiple injuries.
ObjectiveTo systematically review the effect of self-management intervention on the prevention and management of lymphedema in breast cancer patients. MethodsThe Cochrane Library, Embase, PubMed, Web of Science, CINAHL, PsycINFO, SinoMed, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on self-management intervention on the prevention and management of lymphedema in breast cancer patients, from inception to June 16. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.4 software. ResultsA total of 37 references were included, comprising 25 randomized controlled trials (RCTs), 12 controlled clinical trials (CCTs), and a total of 3 697 patients. There were 26 studies in the meta-analysis, and the results of the meta-analysis showed that, compared with the control group, patients in the intervention group exhibited better performance in lymphedema management-related behaviors (SMD=2.65, 95%CI 1.53 to 3.78, P<0.01), symptoms related to lymphedema (SMD=?2.01, 95%CI ?3.66 to ?0.37, P<0.05), occurrence of lymphedema (RR=0.37, 95%CI 0.32 to 0.45, P<0.01), upper limb function (SMD=?1.88, 95%CI ?2.83 to ?0.92, P<0.01), quality of life (SMD=2.79, 95%CI 2.05 to 3.54, P<0.01), and the difference was statistically significant. The intervention mainly included information support, material support, emotional support and decision support. ConclusionThere are currently a variety of self-management interventions, but they mainly focus on information support. Self-management interventions can improve the self-management behavior of breast cancer patients with lymphedema and reduce the impact of lymphedema on patients.
Objective To determine the efficacy and safety of external fixation versus intramedulllary nailing in the treatment of adult tibial shaft fracture. Methods We searched the specialized trials register of The Cochrane Collaboration’s Bone, Joint and Muscule Trauma Group, The Cochrane Library (CENTRAL), MEDLINE (1966 to March 2006), EMBASE (1980 to March 2006) and PUBMED (1966 to March 2006). We also handsearched some Chinese orthopedic journals. Randomized controlled trials (RCTs) and quasi-randomized trials (quasi-RCTs) comparing external fixation versus intramedullary nailing for tibial shaft fractures in adults were included. The quality of these trials was critically assessed. We used the Cochrane Collaboration’s RevMan 4.2.8 for data analyses. Result Three RCTs and two quasi-RCTs involving a total of 279 patients were included. The results of meta-analyses showed that external fixation for tibial shaft fractures in adults may increase the infection rate [RR 2.45, 95%CI (1.31,4.61), P=0.005], and the malunion rate [RR 2.85, 95%CI (1.20,6.79), P=0.02] but may reduce the duration of hospitalization [RR –5.50, 95%CI (–6.99,–4.01)]. The nonunion rate, delayed healing rate, and healing time, were comparable between external fixation and intramedulllary nailing. Conclusion The trials available for this systematic review are too few and small for reliable estimates of the relative effects of external fixation and intramedulllary nailing. Further studies are needed to determine these effects , especially for patients who have GustiloШ C fractures.
Objective To assess the efficacy and safety of tacalcitol and calcitriol on vitiligo. Methods?We searched the MEDLINE (1966 to June 2008), Cochrane Central Register of Controlled Trials (The Cochrane Library, issue 4, 2008), OVID (1978 to June 2008), EMbase (1980 to June 2008), CBM (1978 to June 2008), CNKI (1979 to June 2008) to collect randomized controlled trials (RCTs). We also hand searched relevant journals and conference proceedings. The language was confined to English and Chinese. We screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of included studies, and performed meta-analyses by using the Cochrane Collaboration’s RevMan 4.2 software. Results?Ffiteen trials involving 120 patients in 5 self-control trials and 793 patients in other 10 randomized controlled trials were included and assessed. The time of repigmentation onset of good responders and normal responders in the side treated with a combination of topical talcitol and NB-UVB was shorter than that in the control group [WMD= –?75, 95%CI (–?93.93, –?56.07); WMD= –?48, 95%CI (–?76.36, –?19.64)]. The mean number and cumulative dose of excimer light exposures for initial repigmentation in the side treated with tacalcitol and 308-nm monochromatic excimer light were less than those in the control group [WMD= –?0.78, 95%CI (–?1.02, –?0.54; WMD= –?1.06, 95%CI (–?1.36, –?0.76)]. The mean number of UVA exposures for initial repigmentation and complete repigmentation in the side treated with calcipotriol and PUVA were less than those in the control group [WMD= –?2.67, 95%CI (–?3.06, –?2.28); WMD= –?2.67, 95%CI (–?3.42, –?1.92)], and the cumulative UVA dose for iniitial and complete repigmentation in the combination group were also lower than those in the control group [WMD= –?25.68, 95%CI (–?29.44, –?21.92); WMD= –?27.14, 95%CI (–?34.80, –?19.48)]. The mean time of initial pigmentation was much shorter in the group treated with calcipotriol and corticosteroid was shorter than that in the control group [WMD= –?3.87, 95%CI (–?5.45, –?2.29)]. Conclusion?The limited evidence indicated that combination of topical tacalcitol with NB-UVB or monochromatic excimer light, or the combination of topical calcipotriol with PUVA or corticosteroid shortened the time of repigmentation and decreased the cumulative irradiation dose. The side effects were limited. No obvious effect was seen on re-pigmentation degree.
Objective To assess the efficacy of naloxone for cardio-pulmonary-cerebral resuscitation (CPCR). Methods Randomized controlled trials (RCTs) involving naloxone for CPCR were identified from MEDLINE (1966 – Jun.2006), EMbase (1974 - Jun.2006), PubMed, The Cochrane Library (Issue2,2006), CBM(1978 - Jun.2006) and CNKI (1994 - Jun.2006). The quality of the trials was assessed by two reviewers independently. RevMan 4.2.7 software provided by the Cochrane Collaboration was used for statistical analysis. Results Ten RCTs were included. The quality of included RCTs was low. All the patients were in-patients or out-patients receiving CPCR due to cardial arrest at the age of 18-75 years. Meta-analysis indicated that the resuscitation rate in naloxone group was significantly higher than the placebo group (Plt;0.00001). And the recovery of the brain function in naloxone group was better than in the placebo group(Plt;0.00001) Conclusions Naloxone is effective for CPCR and it may ameliorate its prognosis. Because of the low quality of included trials and the small sample size, more RCTs are required to assess the efficacy of naloxone for CPCR.
Objective To systematically review the efficacy of different exercises on inflammatory cytokines in individuals with overweight or obesity. Methods The CNKI, WanFang Data, VIP, PubMed, EBSCO, Cochrane Library, Web of Science and Embase databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of exercise on inflammatory cytokines in individuals with overweight or obesity from January, 2000 to April, 2021. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. The network meta-analysis was then performed using Stata 16.0 software. Results A total of 63 RCTs were included, 49 of which reported the changes in IL-6, 47 of which reported the changes in TNF-α, and 16 of which reported the changes in IL-10. The results of the network meta-analysis found that compared with those in the control group, aerobic exercise (AE) (SMD=?0.9, 95%CI ?1.4 to ?0.5, P<0.01) and high-intensity interval training (HIIT) (SMD=?1.3, 95%CI ?2.3 to ?0.3, P=0.011) significantly reduced IL-6. AE (SMD=?1.3, 95%CI ?1.7 to ?0.9, P<0.01), combined exercise (COM) (SMD=?0.7, 95%CI ?1.3 to ?0.1, P=0.02), and HIIT (SMD=?1.8, 95%CI ?2.6 to ?0.9, P<0.01) significantly reduced TNF-α; AE (SMD=0.8, 95%CI 0.1 to 1.5, P=0.03) significantly increased IL-10. The cumulative probability ranking results showed that HIIT was the most effective in reducing IL-6 and TNF-α and increasing IL-10, followed by AE and COM, and resistance training (RT) was the least effective. Conclusion Different exercise types have different effects on improving inflammation in individuals with overweight or obesity. HIIT can be suggested as the best exercise program to improve chronic inflammation in individuals with overweight or obesity. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To assess the efficacy and safety of sevoflurane versus ketamine in the anesthesia of child short period surgery. Methods Such databases as EMbase, PubMed, The Cochrane Library, CNKI, VIP, CBMdisc, Ongoing Controlled Trial and Conference Articles were searched from their establishment to April 2011 to collect randomized controlled trials (RCTs) and the quasi-RCTs. The quality of those studies meeting the inclusive criteria was assessed, the data were extracted and the meta-analysis was conducted by using RevMan 5.1.1 software. Results Ten studies involving 600 participants were included. Seven studies showed that the intraoperative heart rate of the sevoflurane group was lower than that of the ketamine group (MD= –11.85, 95%CI –16.47 to –7.23, Plt;0.000 01). Nine studies showed that the revival time of the sevoflurane group was shorter than that of the ketamine group (MD= –29.05, 95%CI –37.98 to –20.12, Plt;0.000 01). Three studies showed that the anesthesia induction time of the sevoflurane group was shorter than that of the ketamine group (MD= –208.45, 95%CI –359.22 to –57.68, P=0.007). Six studies showed that the influence on mean arterial pressure (MAP) had no significante difference (MD= –4.86, 95%CI –10.02 to 0.29, P=0.06). Meanwhile, seven studies showed that the adverse events of the sevoflurane group were fewer than those of the ketamine group (Peto OR=0.29, 95%CI 0.20 to 0.40, Plt;0.000 01). Conclusion The results of this system review show that sevoflurane is more effective than ketamine with fewer adverse reactions, and it provides a new choice for clinical anesthesia for child short period surgery. However, ketamine is still the main drug in clinical anesthesia for the child short period surgery at present, so high quality studies are needed for further clinical researches.
ObjectiveTo assess the efficacy and safety of compound flumetasone ointment for neurodermatitis and chronic eczema.
MethodsWe searched the Medline, Cochrane Central Register of Controlled Trials, EMbase, CBM, CNKI and Wanfang Data to collect randomized controlled trials (RCTs) of compound flumetasone ointment for neurodermatitis and chronic eczema; the retrieval time started from founded date to December 2012. The language was confined to English and Chinese. We performed meta-analyses using the Cochrane Collaboration's RevMan 5.0 Software.
ResultsA total of 22 RCTs involving 2 049 patients with neurodermatitis and chronic eczema were included and assessed. At the end of the 2nd, 3rd and 4th week, the efficacy of topical compound flumetasone ointment (or combined with oral antihistamines) was obviously higher than that of other topical corticosteroid preparations[RR=1.39, 95%CI(1.30, 1.50), P<0.000 01; RR=1.25, 95%CI(1.15, 1.37), P<0.000 01; RR=1.21, 95%CI(1.11, 1.33), P<0.000 1]. Only temporary and slight adverse effects, such as erythema, desquamation, burning and tingling were observed, whereas no serious adverse effects were reported.
ConclusionThe limited evidence demonstrates that topical compound flumetasone ointment (or combined with oral antihistamines) is safe and efficient. More large sampled and multiple central RCTs are required to verify these conclusions owing to the limitations of the present study.
Objective To assess the efficacy and safety of Zhiling decoction for vascular dementia. Methods The Specialized Register of the Cochrane Dementia and Cognitive Improvement Group was searched in Feb. 2004 using the term Zhiling. In addition, we handsearched 83 traditional Chinese medicine journals （1993 to 2004 ）. We included all randomized controlled trials（RCTs）of Zhiling decoction treating people with vascular dementia. We also evaluated the internal validity of the RCTs . If all included RCTs were of high quality and homogeneity, then the meta-analysis was conducted. Results Only one RCT was identified. The outcomes were listed as the followings ： ① The Hasegawa＇ s dementia scale scoring （ HDS ） scores of the patients in Zhiling decoction group were improved significantly from baseline after 8 weeks course of treatment and there was no significant difference in the control group. The HDS scores improvement was greater than control group（P 〈0.01 ）o ② The latency of P3 was shorter in both groups after treatment, and there was a significant treatment effect in Zhiling group （t = -52. 09, 95% CI -69.79 to -34.39, P 〈0. 000 01 ）. The amplitude of 173 increased in both groups after treatment, and there was a non-sigmficant treatment effect in Zhiling group for change from baseline （t =1.40, 95% CI -0.02 to 2.82, P =0.05）. ③ Brain electrical activity monitoring （BEAM） showed that benefits in those treated by Zhiling decoction were higher than those treated by Naofukang with OR9.90 （ 95% CI 3.34 to 29.38）. ④In the Zhiling group serum cholesterol （P 〈0.01 ） , serum triglyceride （P 〈0.01 ） and LPO（P 〉0. 01 ） decreased after treatment. There was an increase in the level of high density lipoprotein （HDL） and superoxide dismutase （SOD） in red blood cells compared with baseline for Zhiling groups （P 〈0.01 ）. ⑤ The cerebral blood flow decreased in both groups after treatment, and there was a significant treatment effect in favour of Zhiling （treatment effect t = -1.03, 95% CI -1.26 to -0.80, P 〈0. 00001 ）.⑥ No side effects on heart, liver or renal function were reported in Zhiling decoction group. Conclusions The currendy available evidence is insufficient to assess the potential efficacy for Zhiling decoction in the treatment of vascular dementia. Just one RCT concerning the management of Zhifing decoction versus Naofukang suggests that Zhiling decoction may be effective in treating vascular dementia. Further randomised, double-blind, placebo-controlled trials are urgendy needed .
Objective To evaluate the efficacy and safety of Tongxiening granule （TXNG） in the treatment of diarrhea-predominant irritable bowel syndrome （IBS） （stagnation of the liver-qi attacking the spleen）. Methods In a prospective, randomized, placebo-controlled, double-blind clinical trial, 60 patients with diarrhea-predominant IBS were randomly divided into the TXNG group （TXNG, 5.0g, 3 times daily; n =30） and the placebo group （placebo, 5. 0g, 3 times daily; n =30）. The treatment was administered for 3 weeks, and the follow-up was conducted for 4 weeks.Results （1）Abdominal pain： The cure rates were 57. 7% vs. 16. 0% （ by per-protocol analysis, PP） and 31.0% vs. 7.1% （ by intention-to-treat analysis （ITT） ; and the overall improvement rates were 92.3% vs. 44.0% （PP） and 82.7% vs. 39.3% （ITT） in the TXNG and the placebo groups respectively （ P 〈0. 05）. （2） Diarrhea ： the cure rates were 46. 2% vs. 20. 0% （PP） and 41.4% vs. 17. 9% （ITT） , and the overall improvement rates were 96. 2% vs 48. 0% （PP） and 86. 2% vs 42.9% （ITT） in the two groups respectively （P 〈0.05）. （3）Traditional Chinese medicine symptoms： the cure rates were 30.8% vs. 4.0% （PP） and 27.6% vs. 3.6% （ITT） ; and the overall improevment rates were 92.3% vs. 48.0% （PP） and 82.7% vs 42.9% （ITT） in the two groups respectively （P 〈0. 05）. The pain duration after treatment in the TXNG group was significantly shortened compared with the placebo group （7.6 ±4. 6d vs 14. 4 ±4. 3d, P =0. 0125）. After 4-week follow-up, it suggested that the recrudescent duration in symptoms related to IBS in the TXNG group was longer than that in the placebo group （11.5 ±5.3 d vs 6.2 ±6.9 d, P = 0. 019）. No adverse effects were found in the TXNG group. Conclusion It was demonstrated that TXNG is effective and safe in the treatment of diarrhea-predominant ms （stagnation of the liver-qi attacking the spleen）.
