Although osteoporosis is often considered asilent disease,it is highly prevalent.It will definately affect the health of elderly people and bring heavy burden to the society.Studies of osteoporosis will also draw great attention in the field of geriatrics.The diagnosis,treatment,and monitoring of osteoporosis have not yet been standardized.Multidisciplinary medical staff should work together along with the cooperation of the patients.

AIM:To retrospectively analyze the lipid metabolism disturbance and subacute inflammation within the microenvironment of follicular fluid between Chinese polycystic ovarian syndrome ( PCOS ) patients and the controls . METHODS:Serum lipid indexes , steroid hormone levels , and inflammatory cell counts were analyzed .The inflammatory cytokine and apolipoprotein levels were detected in the serum and follicular fluid .The mRNA expression of apolipoproteins and cytokines in the granulose cells was determined by real-time PCR.RESULTS: PCOS patients showed typical obesity accompanied with hyperlipidemia and hyperandrogenemia .Significantly elevated inflammatory cell number and cytokine lev-els were detected in both serum and follicular fluid .The mRNA expression levels of the inflammatory cytokines and apoli-poproteins in the granulose cells from the PCOS patients were higher than those from the controls .CONCLUSION:Elevat-ed apolipoproteins reflect systematic hyperlipidemia in the follicular fluid .Serum lipids and cytokines penetrate follicle-ser-um barrier and get into follicle fluid .Meanwhile , increased intake of apolipoproteins or elevated synthesis of cytokines ( IL-1, IL-6 and TNF-α) by granulose cells could also be crucial to stabilize microenvironment of follicular fluid .Oocyte and subsequent embryos are sensitive to the originaal follicular environment .The lipid metabolism disturbance , inflammatory cell infiltration and hyperandrogenemia may possibly disturb oocyte developmental potential .

To explore the clinicopathological characteristics of parathyroid crisis.The data of 3 cases from our hospital and 125 cases reported domestically were retrospectively analyzed.All 3 cases were male.And their disease course was 3 months to 10 years.The serum calcium ranged from 3.72 to 5.19 mmol/l.Among 177 retrieved cases,125 had complete basic data.The male/female ratio was 1∶ 1.17,average age (46 ± 14) (15-75) years and average serum calcium (4.30 ± 0.58) (3.75-7.28) mmol/L.There was no difference between genders or benign and malignant pathological types.Among 117 eases with pathological diagnosis,the most common type was adenoma (74.4％).The ratio of parathyroid carcinoma was higher in males than that in females (33.3％ vs.11.7％).Misdiagnosis rate was 25.0％ upon initial presentations.Case fatality rate stood at 9.4％ (17/180) and half of them died preoperatively.

65 years and 55~65 years respectively,whereas the frequency of IFG in each age group was close,which was more than IGT in the age group of 25~34 years only.The differences of many clinical indexs among 3 groups were significant.The change tendecny of indexs in IFG/IGT group was more obvious.Conclusion The onset characteristics of age and sex are significantly different between IFG and IGT groups,and the latter is more strongly associated with cardiovascular risk factors than the former.Undoubtedly,IFG/IGT group has the highest cardiovascular risk factors.

Objective: To verify that COX-2 promoter can drive its downstream genes specifically in COX-2-positive o-varian cancer cells; Moreover, comparing with CMV promoter, analyze the transcript efficiency of COX-2 promoter. Methods: Contacting the recombinant plasmids named COX-2-BAX and CMV-Luc. After transient transfection liposome-mediated with the plasmids COX-2-Luc and CMV-Luc, respectively, the expression of Luciferase reporter gene was measured in COX-2-positive ovarian cancer cell line-SKOV3 and COX-2-negative colon cancer cell line-SW480. SKOV-3 and SW480 were transfected with COX-2-BAX and CMV-BAX in the same way, respectively. The apoptosis rates were measured through flow cytometry. Results: The recombinant plasmids named COX-2-BAX and CMV-Luc were constructed successfully. The expression efficiency of reporter gene was 1554 ? 86. 5 in SKOV3 and 53. 7 ? 10.9 in SW480 after 24 hours transfected with phPES2, 9851. 7 ? 129. 5 in SKOV3 and 8831. 0 ? 167. 3 in SW480 after 24 hours transfected with CMV-Luc in the same way. The apoptosis rate was 10.4% in SKOV3 and 3.7% in SW480 after transfected with COX-2-BAX, 21.7%in SKOV3 and 25. 6% in SW480 after 36 hours transfected with pcDNA3-BAX in the same way. Conclusions: COX-2 promoter can drive its downstream genes specifically in COX-2-positive ovarian cancer cell lines, but its expression efficiency wasmarkedly lower than CMV promoters. With proper modification, COX-2 promoter is expected to be useful in gene therapy of ovarian cancers.

A 56-year-old man with 1-year history of palpitation, heat intolerance and sweating, was diagnosed as thyrotropin (TSH) -secreting pituitary adenoma based on the symptoms of hypermetabolism, enlarged thyroid gland, inappropriately increased serum TSH concomitantly elevated plasma thyroid hormones and a pituitary tumor demonstrated on magnetic resonance imaging. Long-acting octreotide formulation was administered at a dose of 20 mg intramuscularly. Tumor volume shrinkage and improvement of thyroid function was achieved after a single drug injection; and the thyroid function returned to normal in 28 days. It is suggested that long-acting octreotide formulation might be used as a routine therapeutic approach prior to pituitary surgery, which may enhance the effectiveness of surgery and postoperative recovery.

Micro RNA (miRNA)were small RNAs encoded by the non-coding RNA genes,which functioned through degrada-tion of mRNA or inhibition of mRNA translation.The miRNA was involved in numerous biological processes,including cell proliferation,apoptosis,development and differentiation.And ectopic expression of miRNA could result in diseases,such as neoplastic hematologic disorder and solid tumor.miR-1 06b-25 cluster contained miR-1 06b,miR-93 and miR-25.These miR-NAs were correlated with the development of tumor.Therefore, we reviewed recent articles on the relationship of miR-1 06b-25 cluster with tumor.

Objective To clarify which component plays a pivotal role in metabolic syndrome (MS) which is associated with an elevated risk for cardiovascular diseases and type 2 diabetes. Methods A total of 15564 participants (aged≥25 years old) with high risk for type 2 diabetes in the 1994 National Diabetes Mellitus Surveywere included in this analysis. MS was diagnosed according to the 1999 WHO criteria, and insulin resistance (IR) was defined as being above the 75th percentile of HOMA-IR of the population aged 25-74 years with normal glucose tolerance. Multiple logistic stepwise regression analysis was used to identify the contribution of each component to MS. Results The unadjusted and age-adjusted prevalences of MS in this population was 64.35% and 59.00%, respectively. Age, sex, systolic blood pressure(SBP), diastolic blood pressure(DBP), waist to hip ratio (WHR)/waist circumference and body mass index(BMI), but not IR, plasma glucose level, and plasma triglyceride level, were independently associated with MS, with predicted concordance of 93.8%. The combination of WHR, BMI, SBP, and DBP accounted for 90.2% of the variance of MS, and if BMI was deleted, the remaining three items accounted for 86.1% of the variance. An increment of 0.05 in WHR, or 5 cm in waist circumference, or 10 mm Hg in SBP, or 5 mm Hg in DBP, or 5 kg/m 2in BMI would elevate the risk for MS by 3.35 times, 1.87 times, 1.52 times, 1.46 times, or 1.34 times, respectively. Conclusion The combination of WHR/waist circumference and blood pressure can be used as a simplepredictor for MS in clinical practice.
