ABSTRACT
BACKGROUND: The present network meta-analysis aims to answer the question "what is the best topical intervention for the treatment of recurrent aphthous stomatitis that can provide an acceptable pain relief and promote wound healing?" METHODS: From inception to October 2022, PubMed, Embase, Scopus, Cochrane Library, and China National Knowledge Infrastructure were searched to identify all potentially eligible randomized controlled trials. The primary outcomes were pain scores and/or healing time, while the secondary outcomes were the associated side effects. The Bayesian network meta-analysis accompanied by a random effect model and 95% credible intervals were calculated. RESULTS: Forty-three randomized controlled trials with a total of 3067 participants, comparing 20 different topical medications, were included. Concerning pain reduction, the network meta-analysis failed to show any statistically significant differences when different topical treatments were compared together or even with a placebo at different time intervals. Except for doxycycline, which showed a statistically significant difference in terms of accelerating healing time, other topical interventions showed no statistically significant differences when compared with placebo or with each other. CONCLUSION: Within the limitations of the current network meta-analysis, it seems that: A low to moderate quality of evidence showed no superiority of any topical treatment over others concerning pain reduction, although rank probability tests revealed sucralfate, doxycycline, hyaluronic acid, and chamomile as the most efficacious treatment options at different evaluation times. Hence, further well-designed clinical trials with larger sample sizes are warranted. Topical doxycycline was shown to be the most efficacious intervention in promoting healing of recurrent aphthous stomatitis.

BACKGROUND: Mis Seven implant has become more and more popular in oral implant restoration, and the clinical application in dentate-deficient patients remains to be studied. OBJECTIVE: To explore the short-term effects of the Mis Seven implant system on fixed restorations in dentition loss. METHODS: Nineteen patients undergoing fixed dental prostheses with the Mis Seven system due to dentition loss at the Department of Implants of the Stomatological Hospital of Guangzhou Medical University between April 2015 and December 2017 were included. Three patients had missing maxillary and maxillary dentition and unilateral maxillary teeth. Six patients were loss of maxillary dentition, and there were 10 cases of unilateral mandibular dentition missing. The total dental implants were 134. All cases were implanted and fixed for one stage. Clinical examination, alveolar bone and inter-implant image performance and post-load repair effect at 6, 12 and 24 months of follow-up were used as evaluation indicators. RESULTS AND CONCLUSION: (1) In 134 implants, failure was in 2 cases due to surrounding tissue infection. The success rate of before implant restoration was 98.51％, and the success rate after repair was 100％. (2) The stability of dentition of 19 patients was good, showing good occlusion. No mechanical complications or biological complications occurred. The stability of the restoration was 100％. (3) The vertical absorption of bone tissue around all implants was less than 0.2 mm at 6, 12, 24 months after repair, suggesting that the implant has no obvious edge bone resorption. The gingival tissues around all implants were healthy, and no unhealed inflammation or hyperkeratosis appeared. (4) These results imply that the Mis Seven system in the dentition defect fixation exhibits good short-term clinical results.
ABSTRACT
Objective To evaluate the potential value of IgG antibodies against recombinant PPE65 protein (rPPE65) of Mycobacterium tuberculosis in serodiagnosis of tuberculosis.Methods The gene encoding PPE65 protein of M.tuberculosis was cloned into the PET-28a vector and then expressed in Escherichia coli.The rPPE65 was purified with Ni-NTA affinity and ion exchange chromatography.After dialysis renaturation, the concentration of rPPE65 was determined using Lowry assay.ELISA was used to detect the levels of specific IgG against rPPE65 and recombinant PstS1 protein (rPstS1) in sera from 144 patients with pulmonary tuberculosis (PTB patients), 144 health controls, and 56 patients with non-tuberculosis pulmonary diseases.ROC curves were used to determine cut-off values with the results of IgG antibodies against rPPE65 and rPstS1 for 144 PTB patients and 97 controls with negative PPD skin test.The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of rPPE65 and the combination of rPPE65 and rPstS1 were counted.Results The PPE65 protein of M.tuberculosis was successfully expressed in E.coli. The purity and concentration of rPPE65 were 95% and 0.5 mg/ml, respectively.ROC analysis showed that the cut-off of ELISA using rPPE65 was 0.64.The sensitivity, specificity, PPV, NPV, and accuracy of rPPE65 were 34.7%(50/144), 93.5%(187/200), 79.4%(50/63), 66.5%(187/287), and 68.9%(237/344), respectively.The sensitivity, specificity, PPV, NPV, and accuracy of the combination of rPPE65 and rPstS1 were 59.0%, 91.0%, 82.5%, 75.5%, 77.6%, respectively.Conclusions The rPPE65 of M.tuberculosis appears to be a candidate antigen for serodiagnosis of tuberculosis.Detection of IgG antibodies against the combination of rPPE65 and rPstS1 can increase the sensitivity of serological test for tuberculosis.
ABSTRACT

ABSTRACT
Objective To report the experience of lung transplantation with size reduced graft lung.Methods Four cases receiving lung transplantation with size reduced graft lung were analyzed retrospectively.In case 1,left lung transplantation combined with contra-hteral lung volume mduction.In case 2,right lung transplantation Wag individually performed with partially msecfion of upper lobe of graft lung.In case 3.bilateral sequential lung transplantation wag performed using graft lung with partially resection of bilateral upper lobes.In the remained ease,bilateral sequential lung tansplantation was performed using graft lung with resection of right lower lobe.Results All the size reduced graft lungs had good functions during the peri-operation period.Case 1 and case 2 still survived without obvious complication.Case 3 experienced temporary air leak on the 5th day postoperation and cured by water seal drainage but died of abrupt bronchorrhea due to aspergillus infection on the 32th day postoperation.The last cage experienced smoothly recovery excepted fatal virus pneumonia 2 months postopemtion.Conclusion Size reduced graft lungs can be successfully used for transplantation.
ABSTRACT
Clinical data of 4 patients with chronic obstructive pulmonary disease who underwent allogenic single-lung transplantation were retrospectively analyzed. All cases received corpse donor lungs. One case with diffuse emphysema underwent right lung transplantation. and 3 received left lung transplantation. including one underwent fight lung volume reduction during surgery and 2 cases underwent right lung volume reduction post-transplantation. The inductive treatment with daclizumab or antithymocyte globulin was done and the rejection was prevented with Tacrolimus. mycophenolate and prednisone. The surgery was successfulin 4 cases. One case developed acute rejection on the fifth day post-transplantation. and controlled using methylprednisolone. Two cases discharged successfully, of whom one lived more than 2 years. Two cases died 74 days and 77 days after lung transplantation. respectively.
ABSTRACT
Objective To report the management of single allograft lung transplantation in 4 cases of COPD. Methods Four COPD cases receiving lung transplantation were analyzed respectively. There was diffuse emphysema in double lung in one case and in the remaining 3 cases severe diffuse emphysema that mixed together partially to be bulla but not to the 1/3 of the thoracic cavity. All the cases received the corpse donor. One case with diffuse emphysema received the single-right lung transplantation, one case received simultaneous single-lung transplantation and lung volume reduction and the remaining 2 cases received LVRS 47 days and 28 days after single-left lung transplantation respectively. The inductive treatment with the daclizumab or antithymocyte globulin (ATG) was done and the rejection was prevented with the Tacrolimus, mycophenolate and prednisone. Results The operations were successful in the 4 cases. One case had the acute rejection 5 days after operation and reco- vered after intensive treatment with Methylprednisolone. Two cases discharged successfully and lived to today and the first case lived more than 2 years. Two cases died 74 days and 77 days after lung transplantation respectively. Conclusion In late stage COPD, single allograft lung transplantation is an effective treatment to the bilateral emphysema patients and the lung volume reduction should be done simultaneously to the patients with the bullae that may be ruptured.
