    Objective     To explore the clinical application of the micro-movement sensitive mattress sleep monitoring system (MSMSMS) in the diagnosis of sleep disorders. Methods     233 patients with suspected sleep disorders were tested with MSMSMS and the results were analyzed. Results    Of 233 patients with suspected sleep disorders, 71 cases (30.5%) were insomniacs. According to the apnea hypopnea index (AHI), 31 (13.3%) were normal and 202 (86.7%) were OSAHS, in which the types of central sleep apnea or other were undetermined. Conclusion     MSMSMS can sensitively and accurately determine the sleep respiratory events and monitor the real-time changes of cardiac rhythm and blood oxygen saturation. MSMSMS shows many advantages, such as low physical and psychological load index and low insomnia rate and so on. It can be easily accepted by patients and widely used in clinics.

    Objective    To study the correlation of obstructive sleep apnea hypopnea syndrome(OSAHS) with serum uric acid(UA), serum creatinine(Scr) and blood urea nitrogen(Bun) concentrations. Methods    100 patients with moderate and severe OSAHS and 44 control subjects admitted into our hospital were recruited. The differences of the levels of UA, Scr and Bun among each group were analyzed. Also, the correlations between the apnea hypopnea index (AHI), lowest saturation of blood oxygen (LSaO2) and UA, Scr, Bun were analyzed.  Results     The levels of UA and Scr were significantly higher in groups with moderate or severe OSAHS than those in the control group (P<0.05). UA was positively correlated with AHI (P<0.05), but negatively correlated with LSaO2 (P<0.05). Conclusion    Concentrations of UA and Scr increase with AHI and the degree of anoxemia in patients with moderate and severe OSAHS. High levels of UA and Scr demonstrate that OSAHS is to a certain extent associated with kidney damage.

    Objective     To investigate the Alzheimer associated neuronal thread protein (AD7c-NTP) in urine and serum amyloid A protein (SAA) in patients with obstructive sleep apnea syndrome (OSAS). Methods     52 patients with OSAS were recruited as the experimental group, while eighteen healthy subjects with matched age and BMI were recruited as the control group. The AD7c-NTP and SAA specific monoclonal ELISA method was used to measure AD7c-NTP in morning urine and SAA in serum. In addition, correlations of AD7c-NTP and SAA between apnea hypopnea index (AHI) and the lowest arterial oxygen saturation (LSaO2) were analyzed. All data were processed in SPSS 17.0. Results    Compared with the control group, AD7c-NTP and SAA levels were significantly higher in the OSAS group(P<0.05). AD7c-NTP and SAA were positively correlated with AHI, but negatively correlated with LSaO2.  Conclusion     AD7c-NTP and SAA levels are significantly higher in OSAS patients and correlated with the degree of OSAS. Elevated AD7c-NTP and SAA level may contribute to some increased risks for SD (senile dementia) in OSAS patients.

    Objective     To explore the effect and significance of the TGF-β1 signaling system in laryngeal squamous cell carcinoma(LSCC). Methods    The immunohistochemical method was used to detect expression of TGF-β1, TβRII, and Smad4 in 44 cases of LSCC and 10 cases of normal laryngeal mucosa. Correlation between the results and LSCC progress and metastasis was analyzed. Results     The expression rate of TGF-β1 in the LSCC group was 68.2%, which was significantly different from the normal laryngeal mucosa group(30.0%, P<0.05), and the expression of TGF-β1 was associated with clinical stages and lymph node metastasis(P<0.05). The positive expression rate of TβRII and Smad-4 was 40.9%, 34.1% in the LSCC group  and  80.0%, 80.0% in the normal laryngeal mucosa group(P<0.05). There was a negative correlation between TβRII and clinical stages (P<0.05), but no correlation between TβRII and lymph node metastasis(P>0.05). There was a negative correlation between Smad4 and the clinical index(P<0.05),  including pathological differentiation, clinical stage and lymph node metastasis.  Conclusion    There is a significant correlation between the abnormal TGFβ1/Smad4 signaling system and LSCC progress. Low expression of Smad4 may accelerate lymph node metastasis of LSCC.

     Objective    To study OPN and p53 expressions and detect their correlation and clinicopathological value in laryngeal squamous cell carcinoma (LSCC) and adjacent tissues. Methods     The SP immunohistochemical method was used to study the OPN and p53 expressions in routinely embedded sections of surgical specimens of 44 laryngeal squamous cell carcinomas and adjacent tissues,and clinicopathological features were analyzed. Results    ①The positive rates of OPN and p53 protein were 75.0 %(33 cases)and 65.9%(29 cases)in LSCC, and 13.6%(6 cases)and 2.3%(1 case)in adjacent tissue respectively; ②The OPN expression level was significantly correlated with tumor stage, grade and the presence of lymph nodes, but was not correlated with age, gender and primary tumor site; ③Expression of OPN was positively correlated with that of p53(r=0. 360,P=0.016). Conclusions     OPN expression is higher in LSCC than in adjacent tissue, and may participate in the development and metastasis of LSCC. OPN might be an important biological marker in LSCC prognosis.

    Objective    To explore the difference between expressions of the urokinase-type plasminogen activator (uPA) and microvessel density (MVD) in cancer tissue and adjacent normal tissue of hypopharyngeal squamous cell carcinoma (HSCC) and to study their correlation with invasion and metastasis of HSCC. Methods    Expressions of uPA and MVD of 60 patients with HSCC and 20 cases of paraneoplastic tissues were detected with SP immunohistochemical staining. Results    The positive expression rate of uPA in patients with HSCC was 78.33%, which was significantly higher than that in paraneoplastic tissues(P<0.001).  uPA positive expression was closely correlated with clinical stage, pathological differentiation and lymph node metastases of hypopharyngeal carcinoma (P<0.05).  The MVD number was also correlated with clinical stage, pathological differentiation and lymph node metastases of hypopharyngeal carcinoma (P<0.05 or 0.01). Neither was significantly correlated with patient age and primary anatomic area of HSCC. Expression of uPA had a positive correlation with MVD(r=0.561,P<0.01) in patients with HSCC.The cervical lymph node metastatic rate in patients with uPA positive-expression and high MVD value was 90.91% (20/22), which was significantly higher than that in patients with uPA positive-expression but low MVD value (52.00%), and that in patients with uPA negativeexpression and low MVD value (30.77%) (χ2=9.538,P<0.05). Conclusion    Active angiogenesis and uPA positiveexpression are closely correlated with invasion and metastasis of HSCC. HSCC with uPA positive-expression and high MVD value are susceptible to invasion and cervical lymphatic metastasis. Therefore, uPA and the MVD number may be used as effective indices to evaluate the possibility of invasion and metastasis of HSCC.

    Objective    To investigate the hearing screening situation of newborns in the neonatal intensive care unit (NICU) and compare it with that of newborns in the well-baby nursery. Methods    Hearing screening was carried out in 927 newborns in the NICU and 16353 newborns in the well-baby nursery. All newborns were screened and re-screened with transient evoked otoacoustic emission. Positive cases were evaluated by a diagnostic audiology test. Results    28 cases of sensorineural deafness were founded in the NICU group, of which 11 had hyperbilirubinemias, 9 very low birth weight, 6 ischemic encephalopathy and 2 meningitis. The incidence rate of sensorineural deafness in the NICU group was 3.02% (28/927). There were 50 cases of sensorineural deafness in the wellbaby nursery group, of which 23 had intrauterine infection, 12 hyperbilirubinemias, 10 family history of hearing loss, 3 meningitis and 2 ototoxic drug contact history. The incidence rate of sensorineural deafness was 0.31% (50/16353). There was a significant difference between the two groups(P<0.05). Conclusions    The incidence rate of sensorineural deafness is obviously higher in the NICU group than the wellbaby nursery group. Hyperbilirubinemias, very low birth weight and ischemic encephalopathy are the main risk factors in the NICU group. Intrauterine infection, hyperbilirubinemias and family history of hearing loss are the main risk factors in the well-baby nursery group. More attention should be paid to newborn hearing screening in the NICU.

    Objective    To explore and evaluate the surgical treatment of maxillary sinus benign pathological bone lesions under an image navigation system. Methods    The clinical data of 8 cases of maxillary sinus benign pathological bone lesions from October 2005 to January 2010 in our department were retrospectively analyzed. 64 slice CT three-dimensional imaging was used for diagnosis, and the Caldwell-Luc procedure and endoscopic fenestration with an image guided system were used in the operations. Results    Of the 8 cases, 3 were diagnosed as fibrous hyperplasia of the bone and 5 osteoma; 6 were operated by the Caldwell-Luc procedure and 2 by endoscopic fenestration from the meatus nasi inferior. All the pathological lesions were removed by electric drill. With more than half a year follow-up, 7 cases were gradually free from the symptoms of headache, nasal obstruction and purulent nasal discharge. But 1 patient with fibrous hyperplasia of bone reoccurred, and after being operated twice, a mount of sequestra was taken out of the maxillary sinus which was due to the failure of clearing them out in the first operation. All the patients were healed without serious complications after the operations. Conclusion     An image guided system in maxillary sinus surgery can be effectively used in locating and removing benign pathological bone lesions.

    Objective    To investigate the transient receptor potential vanilloid subfamily member 1 (TRPV1) expressed in migraine rat triggered by nitroglycerin so as to explore the possible mechanism of migraine. Methods    24 Wistar rats were randomly divided into the control group and the model group. The migraine rat model (model group) was established after subcutaneous injection of GTN (10mg/kg) in the neck while the control group had saline. After the model was established, the trigeminal ganglion and dura mater were obtained at 1,2,4,8 hours and expressions of mRNA and protein of TRPV1 were detected by RT-PCR, Western-blot and Indirect immunofluorescence. Results    In the control group, the positive reactions of TRPV1 receptor in the trigeminal ganglion were detected at all designated time points, but, no difference among the time points was found (P>0.05). Compared with the control groups, the relative values of mRNA and protein in the trigeminal ganglion in the model groups were lower at 1h and 2h, but higher at 4h and 8h.  The surface protein TRPV1 receptor at 8 h in the trigeminal ganglion in model rats was higher than that in the control groups, and, similar expression was found in the dura mater. Conclusion   The alteration of TRPV1 receptor expression suggests that the TRPV1 receptor may play a role in the pathogenesis of migraine.

    Objective    To study the clinical characteristics and perioperative management for aged patients with tracheobronchial foreign bodies. Method    A retrospective analysis was performed on 9 aged patients with tracheobronchial foreign bodies. The clinical characteristics and perioperative management in these cases were summarized. Result    First doctor′s office visit in pulmonary medicine were found in 4 of 9 patients and 3 cases were transferred to the ENT department after being diagnosed by  fiberoptic bronchoscopy.In 7 cases,  foreign bobies were removed with  transoral bronchoscopy under topical anesthesia and balanced anesthesia. In the other 2 cases, the foreign bodies were removed with bronchoscopy through the  tracheostoma under topical anesthesia. No complication occurred. Conclusion    For the elderly, if  pulmonary infection is persistent or refractory to antibiotic treatment, tracheobronchial foreign bodies should be suspected. CT scan contributed to the diagnosis and bronchoscopy is the main therapy.

    Objective    To compare the central corneal thickness measurements using pentacam,orbscanⅡand A-ultrasonic pachymeter in myopic eyes. Methods     Central corneal thickness was measured and analyzed with pentacam, orbscan II, and A-ultrasonics.Results     The mean central corneal thickness measured by pentacam,orbscanⅡ,and A-ultrasonics were (536.01±32.33) μm, (539.21±37.45)μm,and(535.39±31.46)μm,respectively. Significant difference was found between orbscanⅡ and pentacam or A-ultrasonic (P<0.001). No significant difference was found between pentacam and Aultrasonic(P=0.095). Positive relationships were found in the results of corneal thickness among the 3 methods.The correlation coefficient r of (orbscanpentacam), (orbscan-A-ultrasonic), (pentacam-A-ultrasonic) were correpondinging 0.917,0.906,and  0.965. The regression equations were “orbscan(μm) = -30.699 +[1.0622 × pentacam(μm)]”, “orbscan(μm) =-38.599 + [1.0792 × A-ultrasonic (μm)]”, and  “pentacam(μm) = 5.424 + [0.9919 × A-ultrasonic (μm)]”. Conclusion    For central corneal thickness, pentacam is superior to A-ultrasonic, but  orbscan /pentacam and orbscan/A-ultrasonic are not substitutable for each other.

    Objective    To observe the clinical efficacy of dispersing wind and clearing heat method to treat postoperative inflammatory reaction of anterior segment. Methods    128 anterior segment surgical cases (including cataract/ secondary intraocular lens (IOL) implantation/glaucoma and trauma of eye) were included and randomly divided into the control group and the treatment group,  each group had of 64 cases. All patients were treated with regular anti-inflammatory medicines and corticosteroid eye-drops. In addition, the patients in the treatment group were treated with extra formula of dispersing wind and clearing heat.  Results    The inflammation after anterior segment performed was quickly contained and inflammation duration became shorter in the treatment group compared with the control group. The treatment efficacy between the two groups was significantly different. Conclusion    The formula of anterior segment performed is remarkably effective for inflammatory reaction of anterior segment postope.
