ABSTRACT

Objective:To investigate the effect of Yupingfeng on hyaluronic acid (HA) and Foxp3+Treg in patients with nasopharyngeal carcinoma.Methods:A total of 58 cases of nasopharyngeal carcinoma were divided into two groups, 30 cases in the treatment group, 28 cases in the control group. Patients in two groups were treated with synchronous radiotherapy and chemotherapy treatment, the treatment group was treated with the Yupingfeng granules through oral administration, 10 g/time, tid for 2 courses. The serum Foxp3+ Treg markers of each group were detected by flow cytometry assay before treatment and after treatment, and the level of HA in serum was detected by radio immunoassay.Results:After radiotherapy and chemotherapy, the contents of Foxp3+ Treg and HA were significantly decreased in two groups (P<0.05), and the decrease of treatment group was more significantly (P<0.01). Correlation analysis showed positive correlation between Foxp3+ Treg and HA (P<0.05). After treatment, the incidence of side effects in two groups was significantly decreased. And there was significant difference between two groups (P<0.05).Conclusions:Combined chemotherapy and radiotherapy with Yupingfeng treatment can decrease the levles of Foxp3+ Treg and HA in nasopharyngeal carcinoma patients. Yupingfeng can also effectively reduce the side effect due to radiation and chemotherapy.

ABSTRACT

BACKGROUND:Calcium citrate has a better solubility than calcium phosphate, calcium sulfate, and other calcium biomaterials. The synthetic calcium citrate has a good denseness, and stably releases calcium ions at a high efficiency during the degradation. Consequently, it may be more suitable for the fil ing of fracture defects, providing needed calcium ions for early fracture healing. OBJECTIVE:To prepare calcium citrate biomaterials with a novel formulation based on the natural bio-mineralized oyster shel s and citric acid so as to expect to get a good application in fracture healing repair. METHODS:Crushing, grinding, and chemical reaction methods were used for refinement. Particle size analyzer, X-ray diffraction, scanning electron microscope, and Fourier transform infrared spectroscopy were adopted for analysis of the size distribution, composition, mineral phases, and micro-morphology. Biological characteristics were evaluated through a simulated body fluid experiment. RESULTS AND CONCLUSION:Oyster shel powder was reacted with saturated citric acid to produce the calcium citrate material that had uniform crystal structure and compact bonding among crystal bodies, and exhibited a certain mechanical ability. The calcium citrate material had a good crystal structure that was conductive to prolong the degradation time. The calcium citrate released calcium ions slowly, and did not produce dramatic changes in the pH value (7.20-7.46) of the surrounding in the dissolution process. With the gradual degradation of calcium citrate materials, Ca2+concentration in solution increased gradual y and stably, and ultimately achieved an appropriate concentration of 7 mmol/L, suitable for osteoblast proliferation and differentiation. Calcium citrate prepared using natural oyster shel has good biological properties, and exhibits a natural superiority to artificial bone materials.

ABSTRACT

OBJECTIVE@#To investigate the clinical characteristics and common etiology of vertigo.@*METHOD@#The clinical data of 168 patients with vertigo in the department of otolaryngolology and neurology from December 2007 to March 2009 were retrospectively analyzed The patients were inquired and examined by pure tone average thresholds, videonystagmography, Dix-Hallpike test, cervical spine X-ray, skull CT and (or) MRI and transcranial Doppler.@*RESULT@#One hundred and thirty-four patients with vertigo were of peripheral origin, with 66 cases benign paroxysmal positional vertigo, 30 cases Meniere's disease, 24 cases sudden deafness, 5 cases vestibular neuritis, 5 cases otitis media ,2 cases ear herpes zosters and 2 cases ototoxicity. Among 26 patients with vertigo of central, 20 patients were vertebrobasilar TIA.@*CONCLUSION@#The most common etiology of the vestibular peripheral vertigo is the benign paroxysmal positional vertigo. Detailed history and the features of vertigo, particular about the duration of vertigo and hearing change, may provide the important evidences for the accurate diagnosis and differential diagnosis of vertigo.

ABSTRACT

OBJECTIVE@#To investigate the clinical characters and therapeutic methods of orbital apex syndrome caused by sinus diseases.@*METHOD@#Six cases of orbital apex syndrome originated from sinus diseases were retrospective analyzed in our hospital from August 2003 to February 2009. Different therapeutic methods were taken according to different causes of disease.@*RESULT@#Four cases of sinus infection,one cases of sphenoethmoidal mucocele, one cases of sinus squamous cell carcinoma. The results of patients with orbital apex syndrome included cure and effectiveness in 2 cases respectively, death from myocardial infarction in one case, and one case is still following up.@*CONCLUSION@#Orbital apex syndrome originated from sinus diseases was rare, which was mainly caused by sinus infection. The key point is the correct etiology diagnosis in early phase. Treatment with endoscopic sinus surgery early is a good effective method for orbital apex syndrome caused by sinus diseases, in the same time with enough dosage of antibiotic and glucocorticoid therapy intravenously.

ABSTRACT

OBJECTIVE To improve the knowledge on the early diagnosis and treatment of the isolated fungus ball sphenoid sinusitis.METHODS A retrospe ctive study was made on10cases of isolated fungus ball sphenoid sinusitis to discuss the clinical manifestation,radiographic features and treatment with endoscopic sinus surgery.RESULTS The common symptoms in10cases were headache and/or bloody nasal discharge.Radiographic features of the disease were a soft tissue image occupying the sphenoid sinus with bones wall thickening.A soft tissue image with calcification in the sphenoid sinus was the feature of CT image.All the patients were treated by nasal endoscopic sinus surgery and cured after followed up for3to18.CONCLUSION Isolated fungus ball sphenoid sinusitis was difficult to diagnose in early stage because of its non-specif ic symptoms.The nasal endoscopy and CT scan make the early diagnosis possible.The diagnosis can be def initely confi rmed by pathological studies.Treatment with endoscopic sinus surgery is an effective method for fungus ball sphenoid sinusitis.
