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.

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.

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.

Objective To discuss the prevention and management of complications of transurethral electrovaporization of the prostate(TUVP).Methods A total of 820 patients underwent TUVP from June 1998 to August 2005.A Wolf electrovaporization system and a F_(24) 12? resectoscope were used.After the seminal colliculus was identified for making a reference plane,the prostatic tissues were removed untill the surgical envelope,and the bladder neck and the apex of prostate were surgically shaped.Results Complications occurred in 124 patients(15.1%,124/820).There were 17 cases of intraoperative complications(2.0%),including massive haemorrhage in 6 patients(0.7%),presymptoms of transurethral resection syndrome in 6 patients(0.7%),and perforation on the juncture of the bladder and the prostate in 5 patients(0.6%).There were 107 cases of postoperative complications(13.0%), including urethral stricture in 18 patients(2.2%),spasm of the bladder in 32 patients(3.9%),secondary hemorrhage in 3 patients(0.4%),retrograde ejaculation in 11 patients(1.3%),temporary incontinence in 13 patients(1.6%),infection of the urinary tract in 24 patients(2.9%),and acute pulmonary thromboembolism in 6 patients(0.7%). Conclusions Preoperative precautions and clear intraoperative exposure are essential to prevent the incidence of complications of TUVP.

Lifelong blood cell production is achieved by the capacity of hematopoietic stem cell(HSC) to differentiate and self-renew.A growing body of evidence suggest that DNA damage induced HSC senescence may be the principal mechanism of aging and HSC exhaustion in response to the stress exposure.Understanding the mechanisms of HSC senescence will help to find new therapeutics that can ameliorate HSC injury induced by chemo-and radiotherapy,elucidate the molecular mechanisms whereby leukemia/cancer stem cell arise and evade cancer therapy by escaping senescence,and identify the novel molecular targets for intervention.
