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.
Objective To analyze the effects and recurrence rate of single miconazole and the miconazole plus living preparation of lactobacillus for the treatment of the uncomplicated vulvovaginal candidiasis. Methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2008) MEDLINE (1966 to January 2009); PubMed (1966 to January 2009); EMbase (1966 to January 2009); CNKI (1966 to January 2009), and the Chinese Biomedicine Database (CBM) (1966 to January 2009) to identify randomized controlled trials of single miconazole versus the miconazole plus living preparation of lactobacillus.The quality of the included trials was assessed. RevMan 5 software was used to conduct meta–analysis. Results Eight trials involving 5 156 patients were included in the effect analysis. Meta-analysis showed miconazole plus with living preparation of lactobacillus was better compared with just miconazole (RR=0.96, 95%CI 0.92 to 1.00, Z=2.12, P=0.03; RR=0.92, 95%CI 0.85 to 0.99, Z=2.17, P=0.03).Seven trials involving 4 852 patients were included in recurrence rate analysis. Meta-analysis showed miconazole plus living preparation of lactobacillus had lower recurrence rate compared with single miconazole (RR=3.72, 95%CI 1.94 to 7.13, Z=3.97, Plt;0.000 1; RR=12.85, 95%CI 8.27 to 19.96, Z=11.37, Plt;0.000 01). Conclusion Currently available evidence shows that the effect in the combined group is better, and the recurrence rate is lower.
With the popularization of digestive endoscopy in children, colonoscopy has been widely used. As the basis of digestive endoscopy, bowel preparation directly affects the diagnosis and treatment results of colonoscopy. Compared with adults, the functioning of important organs of children is immature, and their ability of cognition, communication and tolerance are weak. Their structure of the digestive tract is also significantly different in different ages. However, there have been no existing evidence-based guidelines on bowel preparation for digestive endoscopy of Chinese children. Therefore, it is important to develop evidence-based guidelines for bowel preparation combined with the clinical practice in China. In order to provide guidance and decision-making basis for Chinese pediatricians, we collaborated with multidisciplinary experts, based on existing evidence, adopted the grading of recommendations assessment, development and evaluation (GRADE) approach, followed the Reporting Items for Practice Guidelines in Healthcare (RIGHT) to develop this guideline for bowel preparation related to the diagnosis and treatment of children's digestive endoscopy.
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.
Based on the principle of manual preparation of sclerosing foam with Tessari method, using the analysis of user requirements and combining it with theory of mechanics, we designed an automatic equipment. The device could be used to replace the manual operation, and could overcome the shortcomings of manual sclerosing foam preparation, such as the difficulty in controlling of pushing speed and stroke and poor reproducibility. This automatic device has the functions of adjustable pushing speed, pushing frequency, pushing stroke and is suitable for a variety of different types of syringes. It can not only provide quantitative parameters for the study of foam properties, but also be used for the standardization of clinical sclerosing foam. The experimental study on "the effect of pushing speed on the stability of foam" was carried out with using the device, and the experimental results were quite satisfactory.
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.
Objective To investigate the effect and clinical significance of 3 d and 1 d bowel preparation method for colorectal carcinoma surgery on preoperative gut mucosal barrier function. Methods Plasma levels of D-lactate (D-LAC), diamine oxidase (DAO) and endotoxin (ET) were measured at 2 h before operation in 3 d bowel preparation group (50 cases) and 1 d bowel preparation group (50 cases), 25 cases of inguinal hernia were included as control group. D-LAC, DAO and ET were detected by using enzymatic spectrophotometric assay, spectrophotometric assay and limulus lysate test with azo chromogenic substrate, respectively. Results Preoperative plasma levels of D-LAC, DAO and ET in 3 d bowel preparation group were (10.25±1.43) mg/L, (5.82±0.80) U/ml and (10.11±1.41) ng/L respectively. In 1 d bowel preparation group the corresponding values were (10.19±1.35) mg/L, (5.80±0.81) U/ml and (9.82±1.35) ng/L respectively. There were no significant differences between 3 d and 1 d bowel preparation group (Pgt;0.05), compared with hernia group, 1 d and 3 d bowel preparation group were also no statistically significant differences (Pgt;0.05). Conclusions There are no significant preoperative gut mucosal barrier function damages in patients with 1 d and 3 d bowel preparation for colorectal carcinoma surgery, 1 d bowel preparation for colorectal carcinoma surgery can be performed in colorectal carcinoma patients, and 3 d bowel preparation can be used for certain special colorectal carcinoma patients.
Colonoscopy examination is the gold standard for diagnosis and treatment of colon diseases and screening for early cancer. Good quality of bowel preparation, which is also called intestinal cleanliness, is the prerequisite for full visualization of colonic mucosal lesions and their details. In clinic, more intestinal cleansing agents, such as polyethylene glycol and magneium suifate, have bad taste and high dosage, which can not be tolerated by some patients and affect the effect of bowel preparation. The use of oral adjuvant, add adjuvant to intestinal cleansing agents, new low-volume or very low-volume polyethylene glycol-ascorbic acid preparation methods, can reduce the incidence of adverse reactions, such as nausea and vomiting in patients, improve their tolerance, satisfaction and so on. This article reviews the methods of improving the taste and reducing the adverse reactions of intestinal cleansing agents at home and abroad to offer references for clinical practice.
ObjectiveTo systematically search and sort out the clinical research literature on the treatment of AIDS by traditional Chinese medicine compound preparations by using the evidence map method, and to understand the distribution of evidence in this field. MethodsThe CNKI, WanFang Data, VIP, CBM, PubMed and Cochrane Library databases were electronically searched to collect studies on the treatment of AIDS with traditional Chinese medicine compound preparations from inception to August 2022. The distribution characteristics of evidence were analyzed and presented in the form of charts and words. ResultsA total of 337 articles were included, involving 268 intervention studies, 66 observational studies and 4 systematic reviews/meta-analysis. A total of 92 kinds of traditional Chinese medicine compound preparations were obtained, and the literature quantity of different preparations was obviously stratified, with Kangaibaosheng preparation being the most frequently reported. In recent years, the number of published literature has been declining, the quality of literature is generally low, and the level of evidence is not high. As for the intervention duration, this field tends to have a longer intervention observation period. As for the outcome indicators, the evaluation criteria of some indicators are not uniform, and the characteristics of TCM advantages are not reflected. The quantity and quality of systematic reviews/meta-analyses were insufficient. No normative consensus or guidelines for the treatment of AIDS with traditional Chinese medicine compound preparations had been formed. Conclusionstudies on the effectiveness and safety of traditional Chinese medicine compound preparations in treating AIDS has initially formed a certain scale of evidence group. In the future, it is necessary to further improve the quality of studies, explore outcome indicators that can reflect the advantages of TCM efficacy, and formulate relevant guidelines in a standardized manner.
ObjectiveTo study and compare the effects of inhaled preparations with open airway and conventional inhaled preparation on asthma patients.MethodsThe patients diagnosed with asthma and treated with the same inhaled preparation only who visited the outpatient department of West China Hospital of Sichuan University, were selected as the study subjects from April to September, 2019. The subjects were divided into the test group and the control group according to random ratio 1∶1. The conventional inhaled preparations were used in the control group. The inhaled preparations with open airway were used in the test group. Asthma control, life quality and treatment satisfaction rate were compared between the two groups after 3 months.ResultsA total of 150 subjects were included and one case dropped-off, then 149 effective subjects were obtained in which 75 cases in the test group and 74 cases in the control group. After 3 months’ treatment of inhaled preparations, the proportion of effective asthma control patients in the test group was higher than that in the control group, and the number of patients satisfied with the treatment of inhaled preparations was higher than that in the control group, with statistically significant differences (all P<0.05). The life quality of patients in both groups was improved compared with baseline, and the difference was statistically significant (P<0.05). However, the increase of scores in the test group was more than that in the control group, and the difference was also statistically significant (P<0.05). ConclusionInhaed preparations with open airway is superior to conventional inhaled preparation on asthma patients in asthma control, life quality and treatment satisfaction rate.
