Correlation between allergic rhinitis and childhood obstructive sleep apnea-hypopnea syndrome / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the correlation between allergic rhinitis and obstructive sleep apnea-hypopnea (OSAHS) syndrome in children.@*METHOD@#(1) According to medical history, physical signs, skin-prick test, serum sIgE, endoscopic examination and polysomnography, the incidence of allergic rhinitis was confirmed in 574 cases of childhood obstructive sleeping apnea-hypopnea syndrome in our hospital between July in 2008 to June in 2010. (2) Effects of anti-allergic drugs were observed on 78 children with OSAHS and allergic rhinitis meanwhile.@*RESULT@#(1) 258 cases of allergic rhinitis were confirmed in 574 cases of OSAHS, accounting for 44.9% of the OSAHS cases and 50.4% of all cases of allergic rhinitis during the same period. Most of them were perennial allergic rhinitis (223 cases, 86.4%), and 72.5% of them were aroused by fungal allergen. Compared with other allergen, statistically significant difference was found (P < 0.05). (2) After receiving anti-allergic drugs regularly for 3 weeks, 40 cases suffering from mild and moderate OSAHS and allergic rhinitis, 3 cases out of 38 cases suffering from serious OSAHS and allergic rhinitis showed satisfactory results, while other cases had little improvement.@*CONCLUSION@#Allergic rhinitis is closely related to childhood OSAHS, and perennial allergic rhinitis dominates. The most common allergen is fungal allergen, the second is house and flour dust mites. So for patients of mild and moderate OSAHS with allergic rhinitis, regular anti-allergic drugs can lighten OSAHS effectively and may make patients avoid surgery. Severe OSAHS cases can receive surgical intervention if prior anti allergic therapy fails. Anti allergic therapy should be adopted routinely after tonsillectomy and adenoidectomy in case of hypopnea due to hypertrophy of inferior turbinate or tubal torus in allergic rhinitis.

Aromatase inhibitors and TAM in the treatment of post-menopausal Luminal B breast cancer patients / 中华普通外科杂志

Objective To evaluate a therapeutic strategy using aromatase inhibitors and TAM in postmenopausal Luminal B breast cancer patients. Methods The clinical data of 733 primary breast cancer cases receiving postoperative endocrine thempy from July 2002 to Mar 2005 in Tianjin Cancer Hospital were retrospectively analyzed.Diagnosis was confirmed by pathology in all the cases.All patients were post-menopausal and ER-positive.501 patients were given tamoxifen(TAM 2.5 mg qd,po),232 patients were given aromatase inhibitors(Letrozole 10 mg bid,po).The follow-up time ranged from 36 to 90 months.Median follow-up time was 46 months.Results The disease-free-survival(DFS)rate of Luminal B breast cancer patients in aromatase inhibitors(AIS)group was higherthan that in TAM group(90.6% vs.88.6%,P=0.038).In TAM group,subgroup analysis showed 3-year DFS of node-positive with HER2(+)is lower than that of node-positive with Her-2-negative(88.2% vs.90.4%,P=0.037);3-year DFS of ER+/PR+ group in HER2(+) patients was higher than that of ER+/PR-group(90.8% vs.89.5%.P=0.032).In AIs group,in spite of the axillary lymph node status,there was no significant difference of 3-year DFS between HER2(+)patients and HER2(-)ones(P>0.05).3-year DFS of ER+/PR+with HER2(+) patients was higher than that of ER+/PR-ones with HER2(+)(91.9% vs.90.5%,P=0.029).Hot flush,vaginal bleeding and thromboembolics in AIS group is less frequent,but muscle pain and bone fracture is more common than that in TAM group(P<0.05).Conclusion Compared to TAM, AIs is more effective and safer with postmenopausal Luminal B patients,and the effect is independent on node stams.

A multi-center survey of hypertension and its treatment in patients with maintenance hemodialysis in Shanghai / 中华内科杂志

Objective To study the prevalence,treatment policy and control of hypertension in patients with maintenance hemodialysis, and to analyze the influencing factors of hypertension control.Methods We studied the current status of 1382 patients with maintenance hemodialysis in 11 dialysis centers in Shanghai, among them 809 were male, and 573 were female.Hypertension was defined as systolic blood pressure(SBP) ≥ 140 and/or diastolic blood pressure (DBP) ≥90 mm Hg ( 1 mm Hg = 0.133 kPa).Those who had a history of hypertension and requiring antihypertensive therapy were also diagnosed as hypertension though their blood pressure was within normal range during the survey.Hypertension control was defined as blood pressure ＜ 140/90 mm Hg before each dialysis session.Results The prevalence of hypertension in the hemodialysis patients was 86.3%.The treatment rate and control rate in those patients were 96.8% and 25.5% respectively.More than half (50.4% ) of patients were treated with only one kind of anti-hypertensive drug, and 34.4% with 2 kinds, 14.2% with 3 kinds, 1.0% with 4 kinds or more.Calcium channel blocker (CCB) was the most frequently prescribed drug (61.0%), followed by angiotensin Ⅱ receptor blockers ( 56.4% ), centrally acting anti-hypertensive agent ( 26.4% ), beta blockers and alpha, beta-blockers( 14.0% ).The control rate of hypertension in those hemodialysis people was aggravated by the existence of coronary artery disease.The patients who need more kinds of antihypertensive agents have a poorer control rate of hypertension.The hypertension control rate elevated significantly with the adequate hemodialysis.Conclusions There is a very high prevalence of hypertension in maintenance hemodialysis patients.Although the treatment rate is high, the control rate is unsatisfactory.So the control of hypertension in hemodialysis patient is still a clinical challenge.Appropriate dialysis adequacy, reasonable use of erythropoietin, treatment of heart disease and judicious use of antihypertensive drugs may be helpful to improve the clinical outcome.

The discovery of these kind regulatory elements provides a new approach to regulate gene expression more accurately. In this review, we elucidated the principle of microRNA in regulation of targeting viral vector. The applications of microRNA in the fields of elimination contamination from replication competent virus, reduction of transgene-specific immunity, promotion of cancer-targeted gene therapy and development of live attenuated vaccines were also discussed.

Pharmacokinetics of bacteria bioleaching solution of realgar in rat / 药学学报

The paper is to report the preparation of realgar bioleaching solution (RBS) by bacteria and the comparison of pharmacokinetics of RBS and H3AsO3 (ATO), and the study of its possible change of absorption and distribution of soluble arsenic in rat. The experiment was carried out on Wistar rats given peritoneal injection of RBS at a dose of 0.3 mg x kg(-1) (soluble arsenic content, 0.3 mg x kg(-1)), and rats given ATO at the dose of 0.3 mg x kg(-1) (soluble arsenic content, 0.3 mg x kg(-1)). The arsenic concentrations in many tissues including heart, liver, spleen, lung, renal and brain were determined. The changes of pharmacokinetic parameters and arsenic distribution in different tissues were detected and compared in these two groups of rats. The pharmacokinetic parameters of RBS and ATO are very similar. There is very few distribution of arsenic in the tissues in RBS group, compared with the ATO group. There is significant difference in the content of arsenic between two groups statistically (P < 0.01). It is feasible that we select the bacteria bioleaching solution as a candidate drug, which may be employed for primary change of arsenic compounds including dissolved inorganic arsenic and organic arsenic, in order to improve bioavailability and decrease the amount of arsenic accumulation in animal tissues. In addition, there is significant difference in the change of arsenic compounds between two groups. It can be concluded that, the investigation on application of microbial technology may provide a basis for exploratory research of realgar.

All the patients were respectively diagnosed by brain CT, CTA, MRI, MRA and TCD. Laboratory data included urinary microalbumin-to-creatinine ratio (ACR), routine urinalysis, fasting plasma glucose, 2-hour-postprandial plasma glucose, Scr, uric acid, etc. All the serum creatinine samples were uniformly tested in central laboratory of Shanghai Ruijin Hospital.Glomendar filtration rate (GFR) was estimated by complicated MDRD equation and CKD stage was classified according to K/DOQI guidelines. ResultsA total of 1014 hospitalized patients with cerebrovascular diseases were enrolled during the observation period, with M/F ratio of 559/455 and mean age of (68.56±12.17) years. Cerebrovascular diseases included ischemic stroke (708 cases), hemorrhagic stroke (197 cases) and transient cerebral ischemie attack (TIA) (109 cases). Microalbuminuria (MAU) was detected in 11.2%, while 24.8% patients had proteinuria. The prevalence of CKD was 47.7%. The percentage of these inpatients in CKD stage 1 to 5 was approximately 6.90%, 14.69%, 21.60%, 2.56% and 1.97% respectively. The Logistic regression model showed that the risk factors of short-term (<30 days) prognosis were albuminuria, hyperglycemia (fast glucose) and anemia. ConclusionsThe prevalence of CKD in inpatients with cerebrovascular diseases was 47.7% in Shanghai. It is significant to evaluate CKD among patients with cerebrovascular diseases, especially to use the screening of ACR in the early stage.

Dilingdan Decoction prevents renal interstitial fibrosis in a rat model of unilateral ureteral obstruction / 中西医结合学报

OBJECTIVE: To investigate the preventive and therapeutic effects and the possible mechanisms of Dilingdan Decoction (DLDD), a compound Chinese herbal medicine, on rats with renal tubulointerstitial fibrosis induced by unilateral ureteral obstruction (UUO). METHODS: Sixty SD rats were randomly divided into sham-operated group, untreated group, enalapril-treated group and DLDD-treated group. Blood urea nitrogen (BUN), serum creatinine (SCr), urine protein quantization in 24 hours and pathological changes of the obstructed kidney were observed. The expressions of transforming growth factor-beta1 (TGF-beta1), alpha-smooth muscle actin (alpha-SMA), fibronectin (FN) and laminin (LN) were detected by immunohistochemical method and colored-multimedia pathological image analysis system. RESULTS: Massive inflammatory infiltrates and collagen expression in renal interstitial in the untreated group were observed on the 7th day. Compared with the sham-operated group, percentages of area of TGF-beta1, alpha-SMA, FN and LN expressions in the untreated group were markedly increased (P<0.05), while the percentage of area of interstitial fibrosis was decreased in the DLDD-treated group as compared with the untreated group (P<0.05). On the 14th day, the percentages of area of TGF-beta1, alpha-SMA, FN and LN expressions were declined in two treated groups as compared with the untreated group (P<0.05), but had no statistical difference in biochemical indicators, including BUN, SCr and 24-hour urinary protein. On the 21st day, the level of SCr and the percentage of area of TGF-beta1 expression in the DLDD-treated group were lower than those of the enalapril-treated group (P<0.05). CONCLUSION: DLDD can reduce the excretion of urinary protein and the degree of interstitial fibrosis, and significantly inhibit the expressions of TGF-beta1, alpha-SMA, FN and LN. DLDD is superior to enalapril in protecting renal function after long-time application in rats.

Hormone levels at different menstrual cycle phases and changes of athletic performance in female athletes / 中国组织工程研究

BACKGROUND: What deserves exploration is the relationship between menstrual cycle phase and athletic ability of female athletes, especially the mechanism of athletic performance influenced by different menstrual cycle phases.OBJECTIVE: To compare the hormone level of different menstrual cycle phases and the changes of athletic performance as well as its effect on athletic performance.DESIGN: Single sample and single factor analysis.SETTING: Zhejiang Insftute of Sport Science; College of Education,Zhejiang University; Department of Obstetrics and Gynecology, Zhejiang Provincial People's Hospital.PARTICIPANTS: Specially designed menses card were distributed to all the female athletes in the gig team and track & field team in Zhejiang Province in 2000. Consecutive 3-month recording was made to investigate the status of menstrual cycle phases of female athletes. Twenty-five athletes with regular menses were chosen as subjects, among whom 12 were specialized in gig racing with the average age of 19 years and 13 were specialized in track & field events with the average age of 18 years. They all had more than 3-year training experience, 6 days a week and 4-6 hours a day. They were healthy, had regular menstrual cycle, and had not taken any drug which influences the menstrual cycle.METHODS: Blood samples of the testees were collected at hour 8-9 AM at follicular phase (days 6-10) and luteal phase (days 19-23). Full-automatic chemiluminescence immunoassay equipment was used to measure the level of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), progesterone, and testosterone in serum. coefficient of variability in batch of reagent was ＜5%. Testees accomplished test of their athletic performance and the test of lactic acid 1 to 2 days after blood sample collection. Gig athletes performed 2000 m and 500 m full-strength pull with Concett Ⅱ boating ergometer while track & field athletes performed 100 m and 200 m full-speed running; the time needed was recorded. Gig athletes conducted 2000 m movements on the ergometer with the frequency of 26 times per minute. Track & field athletes carried out three times of 300-meter running with 90% of intensity with 3-minute intervals. Immediately after movements, the lactic acid value was measured following blood collection.Paired t test of the small sample study was used for significance detection.MAIN OUTCOME MEASURES: The level of E2, FSH, LH, proges-terone and blood lactic acid in serum; 2000 m and 500 m performance of gig athletes as well as 100 m and 200 m performance of track & field athletes were measured by the ergometer.RESULTS: Twenty-five athletes accomplished detection of all the indexes and entered the result analysis. The level of FSL, progesterone and testosterone of gig athletes was higher at luteal phase than at follicular phase;however, E2 and LH level did not significantly differ. The level of progesterone and testosterone of track & field athletes was higher at luteal phase than at follicular phase; however, E2, FSH and LH level did not significantly differ. 500 m performance of gig athletes detected by the ergometer, and 100 m and 200 m full-speed running performance of track & field athletes at luteal phase were superior to those at follicular phase, but no significant difference was found in 2000 m performance of gig athletes. When the same loading was accomplished at follicular phase and luteal phase, the lactic acid value at luteal phase was significantly lower than that at follicular phase.CONCLUSION: Tested athletes at luteal phase have good functional status, which may be related to the changes of menstrual cycle hormone level and synergistic effect of various hormones under thes state of athletic movements. It suggests that sufficient attention should be paid to the menstrual cycle of female athletes.

RENAL LESIONS IN MICROSCOPIC POLYARTERITIS NODOSA: A REPORT OF EIGHT CASES / 解放军医学杂志

A clinico-pathological study was carried out on 8 patients with microscopic polyar-teritis nodosa (MPAN). It was found that the renal lesions were very common and severe in this group of patients apart from the typical presentation of MPAN, including fever, myalgias, arteritis and the involvement of hematologic, gastrointestinal and cardiovascular systems. Laboratory pictures were characterized by leucocytosis, anemia and increased serum creatinine. The plasma anti-neutrophil cytoplasmic antibodies were present and thought to be of particular importance. On light microscopy, focal, segmental necrotising glomerulonephritis was discovered which was often associated with extensive crescence formation and vasculitis. We recommend renal biopsy as a valuable tool of investigation in the diagnosis of MPAN.
