Objective To assess the efficacy of topical non-steroidal anti-inflammatory drugs （NSAIDs） in the treatment of osteoarthritis （OA）. Methods MEDLINE, EMBASE, Scientific Citation Index, CINAHL, The Cochrane Library, CBMdisc and abstracts from conference were searched from 1966 to March 30, 2005. Randomized controlled trials （R.CT） comparing topical non-steroidal anti-inflammatory drug （NSAIDs） with placebo or oral NSAIDs in OA were induded. Effect size （ES） was calculated for pain, function and stiffness. Relative risk （RR） was calculated for dichotomous data such as clinical response rate and adverse effect rate. Number needed to treat to obtain the clinical response was estimated. The quality of trials was assessed and sensitivity analyses were undertaken. Results Topical NSAIDs were superior to placebo in relieving pain due to osteoarthritis only in the first 2 weeks of treatment; ES （95% CI） were 0.41 （0. 16 to 0.66） and 0.40 （0.15 to 0.65） at week 1 and 2 respectively. However, the effects were short-lived and no benefit was observed over placebo at the third and fourth week. A similar pattern was observed with function, stiflhess and clinical response RR and number needed to treat. Topical NSAIDs were inferior to oral NSAIDs at week 1, and associated with more local side effects such as rash, itch or burning （RR 5.29, 95% CI 1.14 to 24. 51 ）. Conclusions Only very shortterm （less than 4 weeks） RCTs have assessed topical NSAID efficacy in OA ; after 2 weeks no efficacy above placebo has been obsevrved. There are no trial data to support the long-term use of topical NSAIDs in osteoarthritis.
A new urine analysis core module based on high performance 32-bit microprocessor and high precision color sensor was presented. A novel optical structure and a specific circuit were applied to improve measurement precision and temperature was used to compensate for results in this core module. The information of urine test peice, such as all original data and color RGB value, reflectivity, semi-quantitative level, etc. can be output. The results showed that the measuring precision was about 95% or above with ideal stability and reliability using this presented core module, which can be conveniently applied in various urine analyzers, and can greatly decrease the cost of urine analyzers in development and production.
ObjectiveTo analyze the expression of cold-induced RNA-binding protein (CIRBP) in lung adenocarcinoma and its clinical significance based on bioinformatics, in order to provide a new direction for the study of therapeutic targets for lung adenocarcinoma.MethodsThe CIRBP gene expression data and patient clinical information data in lung adenocarcinoma tissues and adjacent tissues were downloaded from The Cancer Genome Atlas and Gene Expression Omnibus databases. The expression of CIRBP in lung adenocarcinoma was analyzed. Furthermore, its relationship with clinicopathological features and prognosis in patients with lung adenocarcinoma was analyzed. GO and KEGG enrichment analysis were carried out for the screened genes. The CIRBP protein interaction network was constructed by STRING, and the correlation analysis was carried out using the GEPIA online website.ResultsThe expression level of CIRBP gene in lung adenocarcinoma tissues was significantly lower than that in adjacent tissues (P<0.01), and its expression level was correlated with T stage and N stage in clinicopathological features. The prognosis of patients with high CIRBP expression in lung adenocarcinoma was significantly better than that with low CIRBP expression. Univariate and multivariate Cox regression analysis showed that CIRBP was an independent prognostic factor in patients with lung adenocarcinoma. GO functional annotation showed its enrichment in organelle fission, nuclear fission, chromosome separation, and DNA replication, etc. KEGG analysis showed that it was mainly involved in cell cycle and DNA replication. Protein interaction network and GEPIA online analysis showed that the expression level of CIRBP was negatively correlated with the expression level of cyclin B2.ConclusionCIRBP gene is down-regulated in lung adenocarcinoma tissues, and its expression level is closely related to patient prognosis. CIRBP gene may be a potential therapeutic target and prognostic marker for lung adenocarcinoma.
Purpose To investigate mitochondrial DNA (mt-DNA) mutations in optic neuritis of unknow reason (ONUR) and to assess the pathogenic and differential diagnostic values of screening for mt-DNA mutations in ONUR. Method Thirty patients with ONUR were screened for mt-DNA mutations by using SSCP,mutation-specific primer PCR and sequencing. Results mt-DNA mutations were found in 12 out of the thirty patients.All of the mutations were at 11778 position,but no one at 3460 and 15257. Conclusions Quite a number of patients (12/30,40%) with ONUR were caused actually by mt-DNA mutation．Screening for mt-DNA mutation in these patients has a pathogenic and differential diagnostic significance.

Objective To evaluate the effects of enhanced external counterpulsation (EECP) on exercise capacity and quality of life in patients with chronic heart failure. Methods PubMed, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM databases from January 1, 2010 to October 1, 2022 were searched by computer for the randomized controlled trial (RCT) about the intervention of EECP in patients with heart failure. Two researchers independently screened literature and extracted data. The meta-analysis was performed by RevMan 5.3. Results Nineteen RCTs were included. After EECP treatment, 6-minute walk distance (MD=57.37, 95%CI 40.89 to 70.85, P<0.001) and left ventricular ejection fraction improved (SMD=0.85, 95%CI 0.55 to 1.14, P<0.001). B-type natriuretic peptide decreased significantly (SMD=−0.67, 95%CI −1.09 to −0.25, P=0.002). The left ventricular end diastolic diameter (MD=−7.77, 95%CI −11.49 to −4.04, P<0.001), and the left ventricular end systolic diameter were significantly reduced (MD=−8.53, 95%CI −13.47 to −3.60, P<0.001). The quality of life of patients was improved (MD=16.34, 95%CI 0.59 to 32.10, P=0.04). Conclusion EECP can improve the exercise ability and the quality of life in patients with heart failure. However, more and larger well-designed RCTs are still needed to verify this conclusion.
Objective To study some related factors of effect on gluteus muscle contraction and provide the therapeutic basis. Methods The curative effect was assessed in 154 patients who were classified by age, patient’s condition, orthopedic degree in operation and rehabilitation with an average follow-up period of 25 months(ranging from 5 to 36 months).Results The excellent rate of 18-24 years old (25/30) was lower than that of 5 -17 years old(120/124) (Plt;0.05); the excellent rate of slight patients was higher (107/109) than that of serious patients (38/45) (Plt;0.01); the excellent rate from higher orthopedic degree was higher(111/113) than that from lower orthopedic degree(34/41) (Plt;0.01); and the excellent rate of rehabilitation was much higher (107/110) than that of general treatment (38/44) （Plt;0.05）. Conclusion Age, patient’s condition, orthopedic degree in operation and rehabilitation are important factors to affect the curative effect on gluteu muscle contraction.
ObjectiveTo systematically review the predictors of enteral nutrition feeding intolerance in critically ill patients. MethodsThe PubMed, Web of Science, Cochrane Library, Embase, CNKI, WanFang Data, VIP and CBM databases were searched to collect relevant observational studies from the inception to 6 August, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software. ResultsA total of 18 studies were included, including 28 847 patients. The results of the meta-analysis showed that gender, age, severity of illness, hypo-albuminemia, length of stay, postpyloric feeding, mechanical ventilation and mechanical ventilation time, use of prokinetics, use of sedation drugs, use of vasoactive drugs and use of antibiotics were predictors of enteral nutrition feeding intolerance in critically ill patients, among which postpyloric feeding (OR=0.46, 95%CI 0.29 to 0.71, P<0.01) was a protective factor. ConclusionAccording to the influencing factors, the medical staff can formulate a targeted enteral nutrition program at the time of admission to the ICU to reduce the occurrence of feeding intolerance. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the efficacy and safety of laryngeal mask versus endotracheal tubes for laparoscopic surgery.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect the randomized controlled trials (RCTs) about the efficacy and safety of laryngeal mask versus endotracheal tubes for laparoscopic surgery from inception to April, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 16 RCTs involving 1 593 patients were included. The results of meta-analysis showed that: there was no significant difference in the success rate of the first insertion (RR=0.99, 95%CI 0.96 to 1.02, P=0.55). The airway pressure of patients whose position were head higher than foot was significantly lower in the laryngeal mask group than in the tracheal intubation group (MD=–1.20, 95%CI –1.81 to –0.59, P=0.000 1), but there was no significant difference between two groups in reverse position patients (MD=0.48, 95%CI –0.90 to 1.87, P=0.49). The incidence of sore throat (RR=0.58, 95%CI 0.46 to 0.74, P<0.000 01), the incidence of blood stain (RR=0.48, 95%CI 0.30 to 0.77, P=0.002), the incidence of laryngeal spasm/bronchial spasm (OR=0.30, 95%CI 0.11 to 0.80, P=0.02) and the incidence of cough/hiccup (RR=0.10, 95%CI 0.07 to 0.15, P<0.000 01) in the laryngeal mask group were significantly lower than those in the tracheal intubation group.ConclusionThe current evidence shows that compared with tracheal intubation, laryngeal mask can effectively reduce airway pressure of patients whose position are head higher than foot. The risks of various complications are significant higher in tracheal intubation in laparoscopic surgery. Laryngeal mask can maintain patients' normal respiratory functions while reduce damage and do not increase the occurrence of reflux aspiration. Due to limited quantity and quality of the included studies, more high quality studies are needed to verify above conclusion.
Lung cancer is the most threatening tumor disease to human health. Early detection is crucial to improve the survival rate and recovery rate of lung cancer patients. Existing methods use the two-dimensional multi-view framework to learn lung nodules features and simply integrate multi-view features to achieve the classification of benign and malignant lung nodules. However, these methods suffer from the problems of not capturing the spatial features effectively and ignoring the variability of multi-views. Therefore, this paper proposes a three-dimensional (3D) multi-view convolutional neural network (MVCNN) framework. To further solve the problem of different views in the multi-view model, a 3D multi-view squeeze-and-excitation convolution neural network (MVSECNN) model is constructed by introducing the squeeze-and-excitation (SE) module in the feature fusion stage. Finally, statistical methods are used to analyze model predictions and doctor annotations. In the independent test set, the classification accuracy and sensitivity of the model were 96.04% and 98.59% respectively, which were higher than other state-of-the-art methods. The consistency score between the predictions of the model and the pathological diagnosis results was 0.948, which is significantly higher than that between the doctor annotations and the pathological diagnosis results. The methods presented in this paper can effectively learn the spatial heterogeneity of lung nodules and solve the problem of multi-view differences. At the same time, the classification of benign and malignant lung nodules can be achieved, which is of great significance for assisting doctors in clinical diagnosis.
