We present a rare case of dental foreign body from maxillary sinus in a 21-year woman who was hospitalized because of oral cavity and nasal sinus leak for 3 months when doing cheek-bulging action. Admission diagnosis :dental maxillary sinus"foreign body" (left); chronic maxillary sinusitis (left). Computed tomographic scan showed irregular high density shadow in the left maxillary sinus. The "foreign body" was removed via anteri- or prelacrimal recess approach, which was supposed to be the iatrogenic foreign body - alveolar bone.

OBJECTIVE: To investigate the application of endoscopic nasal lateral wall dissection in lesions of the maxillary sinus. METHOD: Ten hospitalized patients with the maxillary sinus lesions were treated with the endoscopic nasal lateral wall dissection. RESULT: All 10 patients were unilateral invasion. Among them, 7 cases were inverted papilloma, 2 cases were recurrent antrochoanal polyps, 1 case was sinusal tooth. The tumors and antrochoanal polyps originated from the every part of the maxillary sinus wall during operation, especially from the anterior and media wall. During 10-62 months follow-up,epithelization of nasal occured and the shape of inferior turbinate was well. All of them had no epiphora. CONCLUSION Endoscopic nasal lateral wall dissection can remain the function of nasal lacrimal duct and nasal cavity,and may provide a new minimally invasive approach for complete resection of lesions of nasal cavity and the maxillary sinus.

Objective To investigate effects of Danhong on the serum levels of CD137, high-sensitivity C-reactive protein (hs-CRP) and homocysteine (Hcy) in patients with non-ST elevation acute myocardial infarction complicating metabolic syndrome. Methods A total of 126 patients with non-ST elevation acute myocardial infarction complicating metabolic syndrome were enrolled and randomly divided into a conventional treatment group and a Danhong treatment group using a random-digit table, with 63 patients in each group. All patients underwent angiography or percutaneous coronary intervention. The patients in the Danhong treatment group treated with intravenous Danhong 20 ml on the basis of conventional treatment for 1 week. The serum levels of CD137, hs-CRP and Hcy were measured at hospital admission and 10 days after treatment. The severity of coronary artery disease was assessed by the Gensini-score. Results The levels of CD137, hs-CRP and Hcy in both groups after treatment were significantly lower than before treatment (conventional treatment group: t 12.393, 17.408 and 9.458; Danhong treatment group: t 16.110, 17.573 and 13.481; all P<0.01), and the Danhong treatment group were significantly decreased than the conventional treatment group (t 2.815, 3.224 and 3.157, all P<0.01). The serum levels of CD137 and hs-CRP before treatment were significantly correlated with Gensini scores in 126 patients (r 0.720 and 0.562,all P<0.01). Conclusions The serum levels of CD137 and hs-CRP are significantly correlated with the severity of coronary artery disease, intravenous Danhong may has protective effect for coronary artery disease via decreasing CD137 and hs-CRP.

Objective To evaluate the effect of hydrogen on mitochondrial fusion during myocardial ischemia-reperfusion (I/R) in aged rats.Methods One hundred and fifty pathogen-free healthy male Sprague-Dawley rats,aged 18 months old,weighing 400-500 g,were divided into 5 groups (n=30 each) using a random number table:control group (group C),sham operation group (group S),group I/R,normal saline group (group NS) and hydrogen-rich saline group (group H).Group C received no treatment.The anterior descending branch was only exposed but not ligated in group S.Myocardial I/R was induced by occlusion of the anterior descending branch of the left coronary artery for 30 rmin followed by reperfusion in I/R,NS and H groups.Hydrogen-rich saline 1 ml/100 g was injected intraperitoneally at 5 min before reperfusion in group H,while normal saline 1 ml/100 g was injected intraperitoneally at 5 min before reperfusion in group NS.The rats were sacrificed at 12 and 24 h of reperfusion,and hearts were removed for examination of the pathological changes and for determination of apoptosis in cardiomyocytes (by TUNEL) and expression of Mfn1 and Mfn2 protein and mRNA in myocardial tissues (by Western blot or real-time polymerase chain reaction).The apoptosis index was calculated.Results Compared with C and S groups,the apoptosis index of cardiomyocytes was significantly increased and the expression of Mfn1 and Mfn2 protein and mRNA in myocardial tissues was down-regulated at 12 and 24 h of reperfusion in I/R,NS and H groups (P＜0.05).Compared with NS and I/R groups,the apoptosis index of cardiomyocytes was significantly decreased and the expression of Mfn1 and Mfn2 protein and mRNA in myocardial tissues was up-regulated at 12 and 24 h of reperfusion in group H (P＜0.05).The pathological changes of myocardial tissues were significantly attenuated in group H when compared with group I/R.Conclusion The mechanism by which hydrogen attenuates myocardial I/R injury is related to promoting mitochondrial fusion and inhibiting apoptosis in cardiomyocytes of aged rats.

OBJECTIVE: To evaluate the effectiveness and usefulness of transnasal endoscopic surgery for the treatment of maxillary cysts. METHOD: Transnasal endoscopic surgery was performed in 13 patients with maxillary cysts that extended to the maxillary sinus or the nasal bottom. Five patients had a radicular cyst, three patients had a dentigerous cyst, three patients had a nasolabial cyst and two patients had a median cyst. After the resection of anterior edge of the inferior turbinate or the nasal bottom, the lateral wall of the inferior nasal meatus was opened. Then, the cyst wall of the maxillary sinus was partially or completely removed under the endoscope. RESULT: The cyst walls were completely or partial removed in 13 patients with maxillary cysts. There were no complications, and postoperative courses were uneventful. The follow-up period ranged from 6 to 36 months, and no recurrence were noted in any of the cases. CONCLUSION Endoscopic transnasal surgery for the maxillary cyst is less invasive than conventional dental approach, and most of the affected teeth can be preserved. This technique appears to be a simple and highly effective surgical treatment for the treatment of patients with maxillary cysts that extend to the maxillary sinus or the nasal bottom.

Objective: To assess the relationship between hemoglobin A₁c (HbA₁c) and hemorrhagic cerebral infarction (HI) in patients with acute cerebral infarction. Methods: From January 2014 to June 2016, in the Lianyungang Hospital Affiliated to Xuzhou Medical University, 426 patients with acute anterior circulation infarction were included. The blood sugar status before stroke was expressed by HbA₁c. HbA₁c and fasting blood glucose (FBG) were measured on the second day after admission. The National Institutes of Health Stroke Scale (NIHSS) was used to assess the severity of neurological function at admission. The modified Rankin scale (mRS) was used to evaluate the prognosis at discharge. CT or MRI/SWI examination was performed to determine whether there was HT. Logistic regression was used to evaluate the risk factors for HT and short-term prognosis after cerebral infarction. Results: Of the 426 patients enrolled, 93 (21.8%) appeared HT, 60 (14.1%) had hemorrhagic cerebral infarction (HI) and 33 (7.7%) had parenchymal hemorrhage (PH). Multivariate analysis showed that HbA₁c and infarct volume were independent predictor of HT. When patients were grouped according to fasting blood glucose (FBG<7.8 mmol/L or ≥ 7.8 mmol/L), the predictive effect of HbA₁c on HT was found in both groups. In multiple Logistic regression analysis, HbA₁c was also a predictor of poor prognosis after stroke (OR=1.482, 95% CI 1.228 -1.788). Conclusions In patients with ischemic stroke, elevated HbA₁c is independently associated with post-infarction HT, and this result doesn′t change even in patients with well-controlled blood glucose. HbA₁c is also a predictor of poor prognosis after stroke. These findings are important for blood glucose management in patients with diabetes and acute anterior circulation infarction.

Secondary rapidly progressive glomerulonephritis (RPGN) can be caused by many diseases and conditions, including vasculitis, systemic rheumatic diseases, infections, drugs and malignancies. Among the secondary RPGNs, malignancy-associated RPGN is extremely rare and causes renal function deterioration within several weeks to months. Thus, timely immunosuppressant therapy can improve renal outcome. Herein, we describe a case of RPGN detected simultaneously with marginal zone B-cell lymphoma. An 82-year-old male patient, who presented generalized edema and oliguria, was diagnosed with crescentic glomerulonephritis and marginal B-cell lymphoma. After the patient was given methylprednisolone pulse therapy, renal function was restored and hemodialysis was successfully discontinued without complications.
