Objectives To assess the effectiveness and safety of any form of therapy compared with glucocorticoid for the treatment of oral lichen planus. Method The Cochrane Library (Issue 4, 2007), MEDLINE (1966-2007), EMbase (1966-2007), CBM (1978-2005), CNKI (1989-2007), and VIP (1989-2007) were searched for randomized controlled trials or quasi-randomized controlled trials. Quality assessment and data extraction were performed by two reviewers independently. Meta-analysis was performed for the results of homogeneous studies by RevMan 4.2.9 software.Results Finally, 14 studies involving 9 therapy methods were included. Four studies were concerned with cyclosporine.We performed a meta-analysis of 3 studies. The results showed there was no statistically significant difference in the curative effect of cyclosporine and the steroid with RR 2.94 and 95%CI 1.03 to 9.97. The results showed that the curative effect of total glucosides of paenia plus topical application of triamcinolone acetonide (RR0.21, 95%CI 0.10 to 0.44),tacrolimu (RR 0.18 and 95%CI 0.05 to 0.72), and pimecrolimus (WMD –0.50 and 95%CI –0.85 to –0.15) were better than glucocorticoid. There was a statistically significant difference between fluocinolone acetonide and retinoic acid in terms of curative effect with RR 3.20 and 95%CI 1.03 to 9.97. The curative effect of mesalazine (RR 0.42 and 95%CI 0.05 to 3.54), Mycostatin paste plus desamethasone paste (RR 1.23 and 95%CI 0.93 to 1.61), triamcinolone acetonide plus vitamin B12 ( RR 0.50 and 95%CI 0.05 to 4.94), chitin (RR 1.30 and 95%CI 0.86 to 1.96) was similar with that of glucocorticoid.Conclusion Statistical analysis showed the curative effect of total glucosides of paenia combined with triamcinoloneacetonide is better than glucocorticoid. Due to the mistakes of theincluded studies designs,,further high-quality,largescale randomized controlled trials are required to confirm the effectiveness and safety of this therapy method.
The wister rats with cirrhotic portal hypertension induced by carbon tetrachloride/ethanal were divided into four groups;①distal splenocaval shunt(DSCS);②portal azygous devascularization (PAD);③mesocaval shunt side to side (MCS);and ④the conrol. Oral glucose toleronce test (OGTT), and glucagon loading test (GLT) were performed on them. The results revealed that the hepatic reserve function of the rats with DSCS and PAD had significant difference as compared with the control (Ｐ＜0.05), but that of the rat with MCS had no significant difference as compared with the control (Ｐ＞0.05).The present study indicates that the hepatic reserve function of rats with DSCS and PAD is better than that of the rats with MCS.
ObjectivesTo systematically review the efficacy and safety of oral drugs for treating women with uncomplicated lower urinary tract infection.MethodsPubMed, The Cochrane Library, EMbase, CBM, WanFang Data, CNKI and VIP databases were electronically searched to collect randomized controlled trials (RCTs) of oral drugs for treating females with uncomplicated lower urinary tract infection from inception to November, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, network meta-analysis was performed by using " gemtc” packages in R 3.5.1 software.ResultsA total of 38 RCTs were included. The results of network meta-analysis showed that: quinolones (RR=1.24, 95%CI 1.11 to 1.37), furantoin (RR=1.21, 95%CI 1.06 to 1.37), trimethoprim-sulfamethoxazole (TMP-SMZ) (RR=1.20, 95%CI 1.06 to 1.35), fosfomycin (RR=1.17, 95%CI 1.04 to 1.31) and penicillin (RR=1.18, 95%CI 1.05 to 1.33) were superior to non-steroidal anti-inflammatory drugs (NSAIDS) in clinical cure. Quinolones were better than fosfomycin (RR=1.07, 95%CI 1.03 to 1.12), penicillin (RR=1.18, 95%CI 1.13 to 1.23) and cephalosporin (RR=1.13, 95%CI 1.08 to 1.19); furantoin was better than penicillin (RR=1.15, 95%CI 1.08 to 1.21) and cephalosporin (RR=1.10, 95%CI 1.04 to 1.17); TMP-SMZ was better than penicillin (RR=1.15, 95%CI 1.09 to 1.21) and cephalosporin (RR=1.11, 95%CI 1.04 to 1.16); fosfomycin was better than penicillin (RR=1.10, 95%CI 1.04 to 1.16) in bacteriological cure. The adverse effect rates of quinolones were lower than furantoin (RR=0.83, 95%CI 0.70 to 0.98), TMP-SMZ (RR=0.88, 95%CI 0.78 to 0.99) and fosfomycin (RR=0.74, 95%CI 0.59 to 0.93), and which of fosfomycin was higher than penicillin (RR=1.33, 95%CI 1.01 to 1.74) and NSAIDS (RR=1.46, 95%CI 1.11 to 1.92). All differences were statistically significant.ConclusionsCurrent evidence shows that uncomplicated lower urinary tract infection should be recommended to therapy containing quinolones. Due to limited quality and quantity of included studies, more high-quality studies are required to verify the above conclusion.
Objective To investigate the possibility of culturing human oral keratinocyte using autologous serum in order to provide theoretical and technical foundation for clinical application of tissue engineering oral mucosa epithelium.Methods The human oral keratinocytes were cultured by the medium containing different concentrations of autologous serum(10%,20%,30%)and fetalbovine serum (10%), respectively. The growth conditions for the cell and the mucosa epithelium in the groups were observed, the cell growth curves were drawn, and the population doubling time (PDT) was counted. Results The results showed that the human oral keratinocyte could proliferate well in the medium containing autologous serum or fetal bovine serum. The differences in the 24hour clone rate and PDT were not significant. Both the area and the thickness of the cultured oral epithelium increased with the increase of the autologous serum concentration, and the difference between autologous serum and fetal bovine serum was significant, especially with the medium containing 20% autologous serum( P＜0.05) . The human nature of the cultured epithelium was demonstrated by the immunofluorescent mouse anti-HLA antigen. Conclusion The autologous serum can replace the fetal bovine serum to culture the oral keratinocyte well, and the cultured oral mucosa epithelium can be better differentiated in the autologous serum than in the fetal bovine serum.
Objective To evaluate the advantages and disadvantages of vascularized free peroneal composite flaps for reconstruction of oral and maxillofacial defects. Methods From November 1999 to December 2002, 28 cases of oral maxillofacial defects were reconstructed with vascularized free peroneal composite flaps, with fibulacutaneous flap in 21 cases and with fibulamyocutaneous flap in 7 cases. Three cases received insertion of dental implants into the fibula flap. The flap size was 3.0 cm×5.5 cm to 8.0 cm ×12.0 cm; the fibula length was 5.5 cm to 16.0 cm. Results Of the 28 flaps reconstructed, 24 survived,3 necrosed partially and 1 necrosed completely. All the 5 implants survived andachieved good bone integration in 3 cases. Twenty-six cases were followed up 1-36 months with an average of 18.5 months, the facial appearance and the vocal function were satisfactory in 23 cases. Conclusion Vascularized peroneal flap has many advantages and is one of the optimal flaps for reconstruction of oral maxillofacial defects.
Objective To systematically evaluate the efficacy and safety of tacrolimus and glucocorticoid for oral lichen planus (OLP). Methods The Cochrane review’s method was adopted and computer-based retrieval was performed on The Cochrane Library, MEDLINE, EMbase, CBM, and CNKI (from their establishment to November 2010) to collect randomized controlled trials (RCTs) comparing the clinical efficacy of tacrolimus in treating OLP with that of triamcinolone. The study was selected according to the inclusion and exclusion criteria, the data were collected, and the methodological quality of the included studies was evaluated. The RevMan 5.0.25 software was applied for statistical analyses. Results Four RCTs involving 164 patients were included. Two studies showed that the tacrolimus effectively reduced lesion area and alleviated pain of patients with OLP. The results of meta-analyses showed that the total effective rate of tacrolimus was not higher than that of glucocorticoid (OR=4.38, 95%CI 0.67 to 28.73), and there was no significant difference between the tacrolimus group and the glucocorticoid group in adverse events during the treatment session (OR=3.49, 95%CI 0.49 to 24.84), and there was no significant difference in recurrence rate between those two groups (OR=0.82, 95%CI 0.27 to 2.46). Conclusion Topical tacrolimus can remarkably improve the OLP sign (lesion area) and symptom (pain), which is in line with the findings of other non-RCTs. The current evidence proves that the tacrolimus is similar to glucocorticoid in terms of the total effective rate of treating OLP, the incidence of side reaction during treatment, and the recurrence rate after stopping treatment. Some studies included in this systematic review apply different assessment methods, hence more RCTs with high-quality, multi-center, and therapeutic evaluation indexes with corresponding evaluation methods are required to provide more reliable evidence.
Objective To investigate the feasibil ity of replacing urinary epithel ial cells with oral mucosa cell to reconstruct tissue engineered urethra by being seeded on bladder acellular matrix graft (BAMG). Methods Eighteen male New Zealand rabbits, aged 10 weeks, weighing 0.3-0.5 kg, were used in this study. Oral mucosa cell of 12 rabbits were isolated and seeded onto a culture dish with a feeder layer of 3T3 and a culture dish without 3T3, respectively. The morphologic change and growth condition of oral mucosa cells were observed by inverted phase contrast microscope after 2 days of seeding. The quantity of oral mucosa cells was counted using cell counting meter; the cell growth curve was drawn and the immunofluorescence staining with broad-spectrum keratin antibody was carried out. The bladders taken from the rest 6 rabbits were decelluled to make BAMG and the tissue of 1 cm × 1 cm was randomly selected to observe the effect of acellularization. The second passage oral mucosa cells cultured with 3T3 were appl ied to steril ized BAMG to obtain a issueengineered mucosa. The tissue-engineered mucosa was assessed using HE staining and scanning electron microscope after being cultured for 1 week. Results Oral mucosa cells seeded onto a feeder layer of 3T3 could be passaged for 7 or 8 generations with homogeneous forms and full function. Oral mucosa cells cultured without 3T3 could only be subcultured for 2 generations before aging and had multiple shapes and different sizes. Oral mucosa cells cultured by the two methods both started logarithmic growth on the 8th day and reached the peak value on the 14th day, which was indicated by the cell growth curve. However, more cells could be obtained through oral mucosa cells cultured with 3T3 than those cultured without 3T3. Oral mucosa cells manifestated green colour fluorescence cultured with or without 3T3. After the cells were removed, the BAMG presented as a porous membrane. The HE staining showed that the effect of acellularization was good and there were no cells at BAMG. The second passage oral mucosa cells cultured with 3T3 were expanded and seeded onto steril ized BAMG to obtain a tissue-engineered mucosa. Good compatibil ity of the compound graft was assessed using HE staining and scanning electron microscope. HE staining and scanning electron microscope showed that oral mucosa cells had good biocompatibil ity with BAMG after the tissue engineered mucosa was cultured for 1 week. Conclusion Oral mucosa cells of rabbit can be cultured in vitro and attain magnitude quantities. Oral mucosa cell also have good biocompatibil ity with BAMG and the compound graft could be a new material for urethral reconstruction.
Objective To investigate the clinical effect ofthe pectoralis major myocutaneous flap and Ti-plate system in repairing mandibular defects caused by resection of oral carcinoma.Methods From November 2001 to February 2003, 32patients with mandibular defect caused by resection of oral carcinoma were treated. Combined radical neck dissection with resection of gingival and mandible was performed on 11 patients with carcinoma of the lower gingival, combined radical neck dissection with glossectomy and mandibulectory on 13 patients with carcinoma of tongue, combined radical neck dissection with resection of floor of mouthand mandible on 4 patients with carcinoma of floor of mouth, and combined radical neck dissection with resection of cheek and mandible on 4 patients with carcinoma of buccal mucosa, respectively. The defects of mandible were associated with soft-tissue component, the sizes of defect ranged from 5.5 cm×7.6 cm to 8.2 cm×10.5 cm. The defects were reconstructed with 6 cm×7 cm to 9 cm×10 cm pectoralis major myocutaneous flaps and Tiplate system. The effect was studied retrospectively. Results Thirty-two cases were followed for 219 months; 29 cases offlaps survived and 3 cases of flaps partly necrosed (10% or less of the skin paddle). The appearance of face was satisfactory in 27 patients, and slight deformity of face was observed in 5 patients. The occluding relation and masticatory function were recovered well. Opening mouth extents ranged from 2.7 cm to 3.4 cm. No temporomandibular arthrosis relating to operation was found in all cases. Conclusion A combination of thhe pectoralis major myocut aneous flap and Ti-plate system is an ideal method for reconstruction of mandible defects associated with soft-tissue component after radical operation of oral carcinoma.
Objective To investigate the thirst status of patients in intensive care unit (ICU) who underwent oral tracheal intubation and ventilator assisted ventilation, and explore its influence factors. Methods A total of 172 patients with oral tracheal intubation admitted in ICU from June 2020 to September 2021 were investigated, and a numerical rating scale was employed for rating their thirst feelings. The patients were divided into a thirst group and a non-thirst group based on thirst status. The thirst status and influence factors of thirst distress were analyzed. Results The incidence of thirst in the ICU patients with oral tracheal intubation and ventilator assisted ventilation was 88.4%, and the thirst score in the thirst group was 7.70±1.17. Single factor analysis showed statistically significant difference between the two groups in sex, medical payment, smoking, drinking, duration of mechanical ventilation, humidification effect, sputum viscosity, gastrointestinal decompression, fasting, continuous renal replacement therapy, diuretics, 24-hour urine volume and liquid balance, heart function grading, sedatives, agitation, sweating, acute physiology and chronic health evaluation Ⅱ, endotracheal intubation depth, body mass index, PCO2, PO2, HCO3–, tidal volume, and sodium ion (all P<0.05). Multivariable regression analysis demonstrated that diuretics, sputum viscosity, sodium ion, alcohol consumption, smoking, intubation depth, and cardiac function were independent influence factors for the occurrence of thirst in the ICU patients who received tracheal intubation (P<0.01). Conclusions The incidence of thirst was high in ICU patients with airway intubation and ventilator assisted ventilation. Diuretics, sputum viscosity, sodium ion, alcohol consumption, smoking, 24-hour urine volume, and cardiac function grading were independent influence factors for the occurrence of thirst in ICU patients with tracheal intubation. It is necessary to implement targeted intervention to prevent and alleviate the thirst degree of patients, reduce the occurrence of related complications, and improve patient comfort.
For patients with partial jaw defects, cysts and dental implants, doctors need to take panoramic X-ray films or manually draw dental arch lines to generate Panorama images in order to observe their complete dentition information during oral diagnosis. In order to solve the problems of additional burden for patients to take panoramic X-ray films and time-consuming issue for doctors to manually segment dental arch lines, this paper proposes an automatic panorama reconstruction method based on cone beam computerized tomography (CBCT). The V-network (VNet) is used to pre-segment the teeth and the background to generate the corresponding binary image, and then the Bezier curve is used to define the best dental arch curve to generate the oral panorama. In addition, this research also addressed the issues of mistakenly recognizing the teeth and jaws as dental arches, incomplete coverage of the dental arch area by the generated dental arch lines, and low robustness, providing intelligent methods for dental diagnosis and improve the work efficiency of doctors.
