ObjectiveTo identify a more popularized preparation protocol of leukocytes-rich platelet-rich plasma (L-PRP) for higher tolerance rate.MethodsThe peripheral blood samples of 76 volunteers (45.0 mL/case) were mixed with 5 mL sodium citrate injection for blood transfusion, and L-PRP was prepared by twice centrifugations. All blood samples were divided into three groups according to the parameters of twice centrifugation: experimental group A (12 cases, 400×g, 10 minutes for the first time and 1 100×g, 10 minutes for the second time), experimental group B (27 cases, 800×g, 10 minutes for the first time and 1 100×g, 10 minutes for the second time), and control group (37 cases, 1 360×g, 10 minutes for the first time and 1 360×g, 10 minutes for the second time). The platelet recovery rate and platelet and leukocyte enrichment coefficient of L-PRP in each group were calculated and compared.ResultsAfter removal of abnormal blood samples (platelet recovery rate was more than 100% or white thrombus), the remaining 55 cases were included in the statistical analysis, including 10 cases in experimental group A, 21 cases in experimental group B, and 24 cases in control group. The platelet enrichment coefficient and platelet recovery rate of experimental group B were significantly higher than those of experimental group A and control group (P<0.05); there was no significant difference between experimental group A and control group (P>0.05). There was no significant difference in leukocyte enrichment coefficient between experimental groups A, B, and control group (P>0.05).ConclusionThe preparation quality of PRP is affected by various factors, including centrifugal force, centrifugal time, temperature, and operation process, etc. Twice centrifugation (800×g, 10 minutes for the first time and 1 100×g, 10 minutes for the second time) is an ideal and feasible centrifugation scheme, which can obtain satisfactory platelet recovery rate and enrichment coefficient with thicker buffy coat, which can reduce the fine operation requirements for operators, improve the fault tolerance rate and generalization.
ObjectiveTo observe the effectiveness and safety of pseudomonas aeruginosa preparation in treating refractory seroma after breast cancer surgery.MethodsA total of 76 patients with refractory seroma after breast cancer surgery who underwent surgery from October 2018 to August 2019 in our hospital were selected. The subjects were randomly divided into two groups. The patients in the control group (n=36) adopted negative pressure drainage connected with indwelling needle in the lower position of the seroma chamber; on the basis, patients in the experimental group (n=400) were injected with pseudomonas aeruginosa preparation into the seroma chamber. The drainage time, total drainage volume, recurrence rate, and incidence of complications of the two groups were compared.ResultsThere were 4 cases in the experimental group and 3 cases in the control group were lost followed-up, so only 69 cases enrolled in data analysis. The drainage time, total drainage volume, and the recurrence rate of the experimental group were all shorter or less than those of the control group (P<0.05). But there was no significant difference in the incidence of complications between the experimental group and the control group (P>0.05), such as fever, inflamed skin, and infection of incision.ConclusionPseudomonas aeruginosa preparation is an effective treatment for refractory seroma after breast cancer surgery, which can shorten the drainage time and promote wound healing.
Day surgery dates back to 1909, when it was first performed by British paediatricians. Anesthesia management for day surgery requires quick onset, early recovery, rapid recovery, and few perioperative adverse reactions. Ensuring the medical safety of patients is the primary condition for the gradual implementation of day surgery. With the continuous development of medical level, the applicable field of day surgery has gradually expanded, and new concepts and progress have also emerged in anesthesia management. This article summarizes the relevant research at home and abroad, and reviews the new progress of anesthesia for day surgery from three aspects: preparation before anesthesia, selection of anesthesia methods, and recovery after anesthesia, in order to provide a reference for anesthesia management of day surgery.
Objective To explore the effects of early enteral nutrition therapy combined with micro-ecologicalpreparation on early intestinal function recovery in patients with severe acute pancreatitis (SAP). Methods The clinical data of 48 patients with SAP treated from January 2012 to January 2015 were retrospectively analyzed. Out of the 48 cases, 23 were treated with early enteral nutrition therapy (the control group), and 25 were treated with early enteral nutrition therapy combined with micro-ecologicalpreparation (the observation group). The counts of white blood cells (WBC), the levels of blood amylase, serum lipase, lactic dehydrogenase (LDH), and the scores of gastrointestinal function 1 day before treatment and on the 7th and 14th day of treatment were observed. The incidences of complications, case fatality rates, and lengths of hospital stay were recorded. Results One day before treatment, the differences in the counts of WBC, the levels of blood amylase, lipase, and LDH between the two groups were not statistically significant (P>0.05). On the 7th day of treatment, the counts of WBC, the levels of blood amylase, lipase, and LDH in the two groups decreased in varying degrees, and the decreasing in the observation group was more obvious (P<0.05). On the 14th day of treatment, the levels of blood amylase in the two groups were almost normal, and the difference between the two groups was not statistically significant (P>0.05); the levels of lipase, LDH and the counts of WBC in the observation group were lower than those in the control group (P<0.05). One day before treatment, the difference in the scores of gastrointestinal function between the control group (1.34±0.76) and the observation group (1.46±0.62) was not statistically significant (P>0.05); on the 7th and 14th day of treatment, the scores of gastrointestinal function in the observation group (0.37±0.18, 0.29±0.06) were lower than those in the control group (0.63±0.32, 0.47±0.08), and the differences were statistically significant (P<0.05). There were significant differences between the two groups in terms of the incidence of total complications and length of hospital stay (P<0.05), while the difference in the case fatality rate between the two groups was not statistically significant (P>0.05). Conclusion Early enteral nutrition combined with micro-ecological preparation is benefit to the intestinal function recovery in patients with SAP.
ObjectiveTo analyze and explore the thyroid defunctionalization method for preoperative preparation of hyperthyroidism patients in endoscopic thyroid surgery. MethodsThe clinical data of 45 cases of hyperthyroidism treated with endoscopic surgery in this hospital from June 2009 to June 2014 were analyzed retrospectively. These patients were divided into study group (n=20) and control group (n=25) according to the preoperative preparation method, the study group was prepared with thyroid defunctionalization method, the control group was prepared with antithyroid drugs and iodine. The intraoperative blood loss, conversion to open surgery, and postoperative complications were compared in these two groups. ResultsThe intraoperative blood loss and the operation time of the study group were significantly less than those of the control group﹝intraoperative blood loss: (120.32±50.26) mL versus (200.63±60.95) mL, P < 0.05; operation time: (120.43±40.56) min versus (180.76±50.92) min, P < 0.05﹞. There was no case of conversion to open surgery in the study group, there were three cases of conversion to open surgery in the control group. The incidence of postoperative complications of the study group was significantly lower than that of the control group﹝10% (2/20) versus 24% (6/25), P < 0.05﹞. ConclusionThyroid defunctionalization method is more suitable as compared with the traditional method for the preoperative preparation of hyperthyroidism in endoscopic thyroid surgery.
Objective To investigate the effects of celecoxib-poly lactide-co-glycolide microparticles (CEL-PLGA-MS) on rat retina after intravitreal injection. Methods A total of 32 male Brown Norway rats were randomly divided into CEL-PLGA-MS group and celecoxib group, 16 rats in each group. The rats in CEL-PLGA-MS group were divided into four dosage group, four rats in each group, which received intravitreal injection of PLGA with celecoxib at the concentration of 40, 80, 160, 320 mu;mol/L, respectively. The rats in celecoxib group were divided into four dosage group, four rats in each group, which received intravitreal injection of celecoxib at the concentration of 40, 80, 160, 320 mu;mol/L, respectively. Phosphate buffer solution (PBS) was injected in two rats as PBS control group. Two rats as normal control group received no treatment. The difference of retinal thickness among groups was measured by optical coherence tomography (OCT). The morphological and histological change of retina was evaluated under light microscope and transmission electron microscope. Results There was no difference of retinal thickness between normal control group and PBS control group (F=0.12,P＞0.05). At the first week after injection, the retinal thickness of CEL-PLGA-MS group and celecoxib group were thicker than that in normal control group and PBS control group (F=9.62, 46.13;P＜0.01). The retinal thickness of celecoxib group was thicker than that in CEL-PLGA-MS group (F=165.15,P＜0.01). The retinal thickness was estimated equal among 40, 80, 320 mu;mol/L dosage groups in CEL-PLGA-MS group (F=4.79,P＜0.01). The retinal thickness of 160, 320 mu;mol/L dosage group were thicker than that in 40, 80 mu;mol/L dosage group in celecoxib group (F=28.10,P＜0.01). At the second week after injection, there was no difference of retinal thickness between CEL-PLGA-MS and celecoxib group (F=3.79,P＞0.05); the retinal thickness of CEL-PLGA-MS and celecoxib group became thinner gradually compare to the first week after injection (F=7.28, 103.99; P＜0.01). At the fourth week after injection, the retinal thickness of celecoxib group was thicker than that in CEL-PLGA-MS group (F=19.11,P＜0.01). The retinal thickness of CEL-PLGA-MS group was approximately the same to normal control group and PBS control group (F=2.02,P＞0.05). The retinal thickness of celecoxib group was thicker than that in normal control group and PBS control group. No considerable abnormality of the retina was seen by light microscope and the retinal thickness corresponded with the values measured by OCT at the first week after injection. The abnormal structures of the retina were seen in 160, 320 mu;mol/L dosage group of celecoxib group and inner changed evidently by the transmission electron microscope. Disordered arrangement of microfilaments, dilated microtubule and some mitochondria vacuolation were observed in 320mu;mol/L dosage group of celecoxib group. Others changed slightly. Conclusions CEL-PLGA-MS has less toxicity on the retina than free-celecoxib after intravitreal injection. The safety of intravitreal injection with CEL-PLGA-MS is better than celecoxib.
ObjectiveTo evaluate the safety and efficacy of Chaihu drop-pill in the treatment of common cold (wind-heat syndrome). MethodsA multi-center, double blind, double dummy, randomized controlled trial was conducted. A total of 479 patients with common cold (wind-heat syndrome) diagnosed between February and August, 2011, were randomly divided into two groups:the trial group (n=359) and the control group (n=120). The trial group received Chaihu drop-pill and Yinchai granule analogue three times a day, while the control group received Yinchai granule and Chaihu drop-pill analogue. The therapeutic courses of both groups were 3 days. Clinical symptoms, syndromes, and adverse effects were observed before and after the treatment. Furthermore, blood, urine and stool test, hepatorenal function test and electrocardiogram were also carried out before and after treatment. ResultsAfter treatment, the healing rates of the trial group and the control group were 32.4%, 20.2% (for full analysis set) and 32.6%, 20.5% (for per protocol set), and the overall response rates were 96.3%, 87.4% (for full analysis set) and 96.5%, 87.2% (for per protocol set). There were significant differences between the two groups (P<0.01). No adverse effects were found in the trial. ConclusionChaihu drop-pill is effective and safe in the treatment of common cold (wind-heat syndrome).
Objective To analyze the effectiveness and effect on pregnant outcome about living preparation of lactobacillus versus metronidazole in the treatment of bacterial vaginosis in pregnancy. Methods We searched PubMed, The Cochrane Library, VIP, CNKI, Wangfang, CBM, FMJS, and FEBMT to identify randomized controlled trials (RCT) of living preparation of lactobacillus versus metronidazole for bacterial vaginosis in pregnancy. The quality of the included trials was assessed. RevMan 5.0.24 software was used for meta-analysis. Results Eight trials involving 1 687 patients were included. The results of meta-analysis showed: no significant difference was found in the effectiveness between the two groups (RR=1.04, 95%CI 1.00 to 1.08, P=0.08); living preparation of lactobacillus had lower recurrence rate and lower premature delivery rate compared with metronidazole (RR=0.16, 95%CI 0.06 to 0.43, P=0.0004; RR=0.56, 95%CI 0.33 to 0.94, P=0.03); no significant differences were found in premature rupture of membrane, puerperal infection, infant of low-birth weight, infant infection, and infant jaundice between the two groups. Conclusion The effectiveness about living preparation of lactobacillus versus metronidazole for bacterial vaginosis in pregnancy is similar, but living preparation of lactobacillus has lower recurrence rate and lower premature delivery rate, the others of effect on pregnant outcome are similar.
ObjectivesTo systematically review the efficacy of dyclonine and lidocaine for preparation before gastroscopy.MethodsPubMed, CNKI, CBM, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) of dyclonine vs. lidocaine for preparation before gastroscopy from inception to December 31st, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by using RevMan 5.3 software.ResultsA total of 11 RCTs were included. The results of meta-analysis showed that: dyclonine could improve anesthetic effect (RR=1.38, 95%CI 1.31 to 1.47, P<0.000 01), and was more capable to remove bubble (RR=1.40, 95%CI 1.28 to 1.52,P<0.000 01), and had superior textures (RR=1.43, 95%CI 1.18 to 1.74,P=0.000 3).ConclusionsOral dyclonine can improve the visual definition of gastric mucosa and anesthetic effect, and has superior textures. Thus, dyclonine can be regarded as a recommended option prior to gastroscopy. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Foam sclerotherapy is one of the major therapies for varicose veins in lower limbs. It is important to know the influence factor of foam stability which is beneficial to curative effect. The present experiment explored influence of 9 kinds of driving speed on foam stability when using the method of Tessari. Syringes of 5 mL were chosen to do this experiment which was carried out at the liquid gas ratio of 1:4 and the environment temperature of 20℃. A home-made automatic sclerosing foam preparation equipment was used to prepare the foam. A camera recorded the entire process of foam decay. And foam stability indexes which includes drainage time, half-life, foam half-life volume and the drainage rate curve, were analyzed. The results showed that when driving speed ranged from 100 mm/s to 275 mm/s, foam drainage time and the half-life showed a trend of rising. When the driving velocity was greater than 275 mm/s, the foam drainage time and half-life time reduced a little. The largest drainage time and the half-life differences were 340.0% and 118.8% compared to their minimum value. Meanwhile the pressure increased with the increase of driving speed, so that the solubility of carbon dioxide increased and the foam half-life volume decreased with the increase of the driving speed. It can be concluded that when using the method of Tessari to prepare sclerosing foam, driving speed has a significant effect on its stability. With driving speed increasing, foam decay mechanism changes from gas diffusion to liquid drainage as the main function, so the foam stability increased at first and then decreased later. The foam is relatively more stable at the speed of 275 mm/s, which could be considered as the best driving speed.
