Objective:To inquiry the variety difference of upper airway caliber OSAHS sufferer and normal person in quiet respiration Method:Twenty OSAHS sufferer who were viewed by PSG and 16 normal adults who hadve no chief complaint of sleeping disease were selected.The curves of the subjects in a respiratory cycle were recorded by respiratory monitoring system in PSG,while the morphological changes in the harynx of all subjects were observed by fiberscope in a calm respiratory cycle,and then both of the two processes simultaneously were recorded on the same computer.According to the different stages of respiratory cycle by analyzing respiratory curve the video had been edited into pictures about the various anatomical areas in the upper airway,he cross section area and the dimension of palate and lingua and root of the tongue region upper irway wereas studied by the image tools in computer,and the changes of areas and dimensions at palate,and lingua and root of the tongue region upper airway were calculated.Result:It was found that there wasis a morphological change f the upper airway with the respiratory movement in the both groups.The upper airway caliber decrease with inspiration begin and reach the most narrowing at the end of inspiration,then upper airway caliber enlarges with the expiration begin and reach the most widening at the end of expiration.No matter the normal group or the OSAHS roup has the obvious changes in the palate and lingua region on the diameter,the cross section area and the dimension in respiration.The changes in the palate and lingua region on the diameter,the cross section area and the dimension of OSAHS group were greater than normal group.No matter OSAHS group or normal group on the diameter nd cross section area change in the palate was obviously more than the tongue area and the root of tongue area.The changes of OSAHS group on the dimension in the palate were greater than the tongue area and the root of tongue area.Conclusion:There are periodically changes of upper airway during respiration cycle in normal adults and SAHS patients.The effects of respiration on upper airway caliber of OSAHS patients are more obviously than normal adults.and the increasing effects in OSAHS patients is one of OSAHS etiology.

This paper introduces the airway care of a patient with motor neuron disease treated with mechanical ventilation for eight years. The airway care for the patient focused on individualized suctioning,measures to prevent atelectasis such as lung hyperinflation,adjustments of ventilator parameters,regular weaning exercise,as well as measures to prevent ventilator-associated pneumonia such as prevention of aspiration,strict disinfection and isolation,wound care of tracheotomy. The ventilator-associated pneumonia was effectively prevented. Effective nursing care for patients with long-term mechanical ventilation can prevent atelectasis and ventilator-associated pneumonia.

Object To establish a process for the preparation of QINGXUE JIANGZHI CAPSULE(Hemocathartic Antilipemia Capsule)  Methods The study was carried out by uniform experimental design guided by the content of total organic acid and polysaccharide in the resulting preparation, to optimize the ratio of solvents used for the extraction, time needed for the decoction and alcoholic concentration for precipitation Results The most favorable preparative conditions were: decocting the drug twice with 10 times of water for 60 min each time, and precipitate the product at a concentration of 50% alcohol Conclusion Products prepared by this process ensured the content of total organic acid with no loss of polysaccharides

Objective To analyze the clinical effects of low molecular heparin calcium on early onset severe pre-eclampsia.Methods Sixty patients with early onset severe pre-eclampsia at 26-34 weeks of gestational age were divided into treatment group(28 cases)and control group(32 cases).The conventional treatment was delivered in control group and low molecalar heparin calcium(LMWHC)was used in treatment group additionally.The time of prolonged gestational age,umbilical arterial S/D ratio,amniotic fluid index,placenta weight,neonatal weight and Apgar score were measured in two groups.Results The time of prolonged gestational age was 10.19 ±4.57days in treatment group and 6.14 ±3.56 days in control group,which were significantly different(P ＜ 0.01).Umbilical arterial S/D ratio,amniotic fluid index,placenta weight and neonatal weight were all significantly different between the two groups(P ＜ 0.05).Neonatal Apgar score in treatment group was remarkably improved(P ＜ 0.01).Conclusion LMWHC treatment in the patients with early onset severe pre-eclampsia could extend gestational age,increase neonatal weight and improve perinatal outcomes.

OBJECTIVE: To inquiry the variety difference of upper airway caliber OSAHS sufferer and normal person in quiet respiration. METHOD: Twenty OSAHS sufferer who were viewed by PSG and 16 normal adults who hagve no chief complaint of sleeping disease were selected. The curves of the subjects in a respiratory cycle were recorded by respiratory monitoring system in PSG, while the morphological changes in the pharynx of all subjects were observed by fiberscope in a calm respiratory cycle, and then both of the two processes simultaneously were recorded on the same computer. According to the different stages of respiratory cycle by analyzing respiratory curve the video had been edited into pictures about the various anatomical areas in the upper airway, the cross section area and the dimension of palate and lingua and root of the tongue region upper airway whereas studied by the image tools in computer, and the changes of areas and dimensions at palate, and lingua and root of the tongue region upper airway were calculated. RESULT: It was found that there wasps a morphological change of the upper airway with the respiratory movement in the both groups. The upper airway caliber decrease with inspiration begin and reach the most narrowing at the end of inspiration, then upper airway caliber enlarges with the expiration begin and reach the most widening at the end of expiration. No matter the normal group or the OSAHS group has the obvious changes in the palate and lingua region on the diameter, the cross section area and the dimension in respiration. The changes in the palate and lingua region on the diameter, the cross section area and the dimension of OSAHS group were greater than normal group. No matter OSAHS group or normal group on the diameter and cross section area change in the palate was obviously more than the tongue area and the root of tongue area. The changes of OSAHS group on the dimension in the palate were greater than the tongue area and the root of tongue area. CONCLUSION There are periodically changes of upper airway during respiration cycle in normal adults and OSAHS patients. The effects of respiration on upper airway caliber of OSAHS patients are more obviously than normal adults, and the increasing effects in OSAHS patients is one of OSAHS etiology.

OBJECTIVE: To investigate the value of the endoscopy in the operation of microvascular decompression (MVD) for the hemifacial spasm by approach of postauricular suboccipital to the cerebellopontine angle (CPA) with posterior auricular small incision. METHOD: Two hundred and eighty-six cases of hemifacial spasm had received the operation of MVD with endoscopy by approach of postauricular suboccipital to the CPA. RESULT: Responsible blood vessels were found in 285 cases (99.7 percent), including 264 cases of anterior inferior cerebellar artery, 21 cases of basilar artery. The root entry zone of the facial nerve were completely decompressed with Teflon. There is no responsible blood vessels but adhesion in 1 cases (0.3 percent). After surgery, hemifacial spasm immediately disappeared. House-Brackmann(1985) grading system was used to evaluated the recovery of facial nerve function. After 1 week of operation 196 cases' facial nerve function are stage 1/6, 62 cases' are stage 2/6, 23 cases' are stage 3/6, 4 cases' are stage 4/6, 1 cases' is stage 5/6. And after Six months of operation, 274 cases' are stage 1/6, 10 cases' are stage 2/6, 2 cases' are stage 3/6. After 1 month of operation there is no significant change of hearing in 238,there are 35 cases of hearing loss less than 20 dB, 10 cases of hearing loss more than 20 dB, but less than 50 dB,3 cases of hearing loss more than 50 dB. Ear-nose cerebrospinal fluid leakage occurred in 2 cases are cured. During 1 year to 4 years following-up, only 3 (1.0 percent) preliminary suffered relapse,among which 1 case was cured by the secondary operation. The long term cure rate was 99.3 percent without occurrence of serious complications such as death. CONCLUSION The microneurosurgery of MVD for the treatment of hemifacial spasm is an ideally functional and etiotropic operation. It is useful not only to discover the responsible blood vessels which are regarded as those pressing the root entry zone of facial nerve,but also to protect the function of the brain tissue and nerves as well. It is a safe, minimally invasive and efficient operation. To avoid the complications, enough knowledge of the craniotopography and skilled technique of endoscopic operation are primary.
