OBJECTIVE To explore the causes, predilection sites and treatment of nasal sinus mucoceles after hypophysectomy.METHODS The clinical data of 7 cases with nasal sinus mucoceles after hypophysectomy diagnosed and treated in our Department from Jan.1998 to Aug.2007 were retrospectively studied.RESULTS The mucoceles were located at ethmoid sinus in 2 cases,frontal sinus in 2 cases,frontal and ethmoid sinuses in 3 cases.All of the 7 cases underwent mucocelectomy under nasal endoscope or a combined endoscopic intranasal and extra-nasal approach.No recurrence was found after follow up for 1 to 3 years.CONCLUSION The causes of nasal sinus mucoceles after hypophysectomy are the change of the anatomic structure of nasal cavity after surgery.The stenosis,adhesion of middle nasal meatus or obstruction of the sinus ostium are found in all the patients.Intranasal endoscopic surgery or combined with extra-nasal approach is the first choice for nasal sinus mucoceles.

Objective: To anal yze the reasons for the increasing Chinese residents’ self-medication, and provide references for reasonable positioning and development of self-medication. Methods:Using the National Health Service Survey data (1993, 1998, 2003, and 2008), and use multivariate logistic regression analysis to study the influencing factors of self-medication. Results: Chinese residents’ self-medication have differences in the both time and space dimensions. The influencing factors of medical decision include the demographic characteristics of the diseased residents, medical insurance system, the available of specialized medical services space, family economic conditions, healthy living behaviors, daily health situation, two-week morbidity cognition and two-week morbidity outcomes etc. Conclusion: The alternative function of self-medication determines its reasonable development space. The increasing rate of Chinese residents’ self-medication has many influencing factors.

In recent years, Chinese residents’self-medication has a rapid upward trend. From the perspective of behavioral economics, it analyzes the reasons for the increasing proportion of Chinese residents’self-medication which has been tested by four data of National Health Service Survey, and provides objective understanding reference for the self-medication.

In recent years, there is a rapid upward trend of Chinese residents’self-medication. It analyzes the formation mechanism of self-medication from three directions: inheritance mechanism, power mechanism and strengthening mechanism. It explains the cause of rapid rise of self-medication, and provides useful lessons for objective understanding of self-medication.

Objective To explore the key points of nursing for neonates with hypoxic-ischemic encephalopathy detected by 18F-fluorodeoxyglucose positron emission tomography.Methods The features of nursing for 58 cases neonates with hypoxic-ischemic encephalopathy detected by 18F-fluorodeoxyglucose positron emission tomography were analyzed and summarized.Results 55 cases with hypoxic-ischemic encephalopathy detected by 18F-fluorodeoxyglucose positron emission tomography smoothly with pertinent nursing,only 3 cases had not completed the procedures because of change of their conditions.Conclusions Pertinent nursing was important for neonates with hypoxic-ischemic encephalopathy detected by 18F-fluorodeoxyglucose positron emission tomography because it could help them complete the procedures smoothly and make the results more accurate and satisfying so it is worthy of wide use clinically.

Objective:To measure serum level of cystatin C (Cys C)in patients with essential hypertension (EH)and analyze its correlation with pulse pressure (PP).Methods:A total of 60 EH patients and 30 cases with normal physi-cal examination results were selected.According to PP level,EH patients were divided into PP>60mmHg group (n=29)and PP≤60mmHg group (n=31).Serum Cys C concentration was measured by latex particle-enhanced immu-noturbidimetric method in two groups,and the results were statistically analyzed.Results:Cys C level of PP >60mmHg group was significantly higher than that of PP≤60mmHg group,and the both groups were significantly higher than that of normal control group [(1.40±0.06)mg/L vs.(1.19±0.54)mg/L vs.(0.72±0.20)mg/L], P <0.05 all;linear correlation analysis indicated that Cys C level was positively correlated with PP (r =0.325,P <0.05)and systolic blood pressure (SBP,r = 0.399,P < 0.05),and PP was positively correlated with SBP (r =0.876,P <0.01)in EH group.Conclusion:Cys C level is positively correlated with PP in EH patients.Cys C level can be used as an early index detecting renal function damage caused by hypertension.

BACKGROUND:In the whole world, spinal cord injuries caused by trauma lead to more than 180 000 people presenting with permanent impairment annualy. A large number of experiments have confirmed in recent years, under physiological conditions, microRNA has specific expression and plays an important role in the nervous system. OBJECTIVE: To discuss the changes in microRNA expression induced by injuries as wel as the pathophysiological significance in spinal cord injury, and to explore the development potential of microRNA in tissue-engineered and clinical repair of spinal cord injury. METHODS:A computer-based search of PubMed and Chinese Journal Database was performed for related articles published from January 2000 to December 2014 using the keywords of “SCI, microRNA, transcriptional control, clinical research progress” in English and Chinese. Finaly, 38 articles were included for result analysis. RESULTS AND CONCLUSION: Mechanical injury initialy triggers a series of complex secondary damages, including nervous, vascular and immune systems, which can influence the severity of spinal cord injury to a great extent. Secondary damage to the spinal cord is mainly attributed to the activation and deactivation of some specific genes associated with celular and biochemical mechanisms, such as cysteine aspartate specific protease (caspase) gene family, apoptosis related protein Fas and its ligand Fasl system, P53 gene, apoptosis related gene Bcl-2 family. Recent studies have proved that the functional activation of microRNA expression is the key to spinal cord injury. With the development of biological information engineering, studies and controling technologies associated with microRNA expression have been gradualy dominated, some clinical application based on microRNA technology has entered the clinical trial stage. It is believed that with the continuous development of technology and decrease of cost, permanent dysfunction due to spinal cord injury can be regulated and repaired through the microRNA technology at gene level in the future.

Purpose To study the value of the ultrasonic imaging in the diagnosis and differential diagnosis of benign and malignant breast tumor. Methods Color doppler ultrasound examination were conducted in 262 cases of patients with breast tumor. The mor-phology of the tumor, edge, envelope, internal echo, microcalcification, length and breadth ratio, axillary lymph node and blood-flow signals of color doppler in breast tumors were observed and these results were compared with the pathological observation postoperation. Results There were 314 tumors in all cases, the coincidence rate in the diagnosis of benign breast diseases with ultrasonic imaging and pathological diagnosis was 97. 3%, the misdiagnosis rate was 2. 7%. The coincidence rate in the diagnosis of breast malignant tumors with ultrasound imaging and pathological diagnosis was 92. 9%, the misdiagnosis rate was 7. 1%. There were statistically signif-icant differences between benign tumors and malignant tumors in the tumor shape, edge, echo, microcalcification, length and breadth ratio, axillary lymph node imaging characteristics (P<0. 01). Conclusion Ultrasound imaging can be more accurate diagnosis and i-dentification of benign and malignant breast tumors.

Fire-dragon moxibustion is a modified moxibustion method based on the traditional moxibustion therapy. It’s more easy-to-operate, has higher security, and is more significant in supplementing yang qi. Via extensive and intensive hot stimulation, fire-dragon moxibustion can activate yang qi inside human body, regulate Zang-fu organs, modulate immune function, and finally achieve the goal of preventing and treating diseases.
