Objective To investigate the occurrence and influencing factors of perimenopausal syndrome (MPS) and natural menopause women age 40-60 years in Guiyang city, with the purpose of providing information for planning care for menopausal women. Methods A convenient sampling was conducted among 40-60 years old healthy women visiting the three Medical Examination Centers of affiliated hospital of Guizhou Medical University, 1594 subjects were interviewed using a self-designed questionnaire. Improved Kupperman Scale was used to evaluate the MPS. Results The percentage of MPS in the 40-60 years old women is 61.60%, of them, the proportion of mild, moderate and severe cases were 38.96%, 21.52% and 1.13% respectively. Mild and moderate account for the most cases. The top 5 symptoms of MPS were:mood agitation (60.85%), wakefulness (58.22%), muscle or joint ache (57.40%) , fatigue (57.09%) and dizziness (48.68%). The incidence of MPS was related to the following factors: age, marital status, degree of education, family monthly income, current menstrual conditions, age of first sexual life and the frequency of pregnancies and deliveries. The occurrence of MPS were associated with age, educational status,family income,current menstruation condition, age of first sexual intercourse and number of pregnancies. As age increases, the severity of MPS arise. With menstrual changes from normal to irregular and menopause, the rate and severity of MPS increased. With the frequency of pregnancies increases, the possibility of moderate and severe degree of PMS increase. The natural menopause age of healthy women in Guiyang was 49.17 ± 3.12. Conclusion The occurrence of perimenopausal syndrome was related to age,current menstruation condition and frequency of pregnancies. Care for perimenopausal period should start as early as possible.

AIM: To explore the role of basic-fibroblast growth factor (bFGF) in the development of pulmonary hypertension induced by hypoxia. METHODS: 1) The pulmonary arteries of SD rats with hypoxia for one and two weeks were isolated, from which the total RNA were extracted by acid guanidinium thiocyanate-phenol-chlorform .Then the levels of mRNA were measured by RT-PCR. 2) About 3mm-long arterial rings cut from SD rat pulmonary arterial stem were suspended between stainless steelhooks in chamber with warmed (37℃) Kreb's solution. Different concentrations of bFGF were added in a cumulative fashion into the chamber where the rings were suspended. The cumulative concentration response curve was obtained. RESULTS: 1)The levels of bFGF mRNA in pulmonary artery of rats with hypoxia were increased significantly compared with those that without hypoxia (2578?384 counts?min -1 (control) vs 5303?756 (hypoxia) for 1 week and 4054?547 (hypoxia) for 2 weeks, P all

Acute myocardial infarction complicated by cardiogenic shock and left main coronary artery disease is called left main shock syndrome. It is reported that the morbility and mortality of the syndrome is approximately 0.46%and 55%-80%, respectively. However, the best treat-ment strategy in these cases is unknown. In this article, we present a patient with LMSS who successively underwent emergency percutane-ous coronary intervention and coronary artery bypass grafting with hemodynamic support within 5 days. The patient is now on his three month uneventful out-patient follow-up.

Objective To explore the role of a novel regulatory molecule-microRNA in the hydroxycamptothecin-resistant human colon cancer cell line SW1116/HCPT in order to provide a new reversal target for muhidrug resistance.Methods MicroRNA expression profiling in the hydroxycamptothecin-resistant human colon cancer cell line SW1116/HCPT were detected by microRNA array using microRCURYTM LNA Array V8.1 to screen multi-drug resistance(MDR)-related microRNAs.Specific stem-loop primers were used for reverse-transcribing cDNA and the expression of some MDR-related microRNAs were analyzed by the real-time PCR.Results The absorbance ratios of total RNA used for total RNA preparation was further confirmed by denaturing agarose gel electrophoresis.Compared to SW1116,28 microRNAs were down-regulated and 36 microRNAs were up-regulated in SW1116/HCPT cell line.The expression of two down-regulated microRNAs(hsa-miR-452 and hsa-miR-373*)and one up-regulated microRNA(hsa-miR-506)were confirmed by real-time PCR.The results of hsa-miR-452 and hsa-miR-506 were consistent with microRNA array nalysis,however,the expression of hsa-miR-373* may play a key role in the process of hydroxycamptothecin-resistant human colon cancer cell line SW1116/HCPT.

Meth?ods Soil?transmitted nematode eggs in feces were detected by the Kato?Katz method,and the eggs of Enterobius vermicularis were detected by the cellophane tape method in children. The soil samples were collected from vegetable ,fruit and other crop fields of 15 residents randomly to detect hookworm. Results The stool samples from 1 002 residents were examined and the soil?transmitted nematode infection rate was 20.06%(201/1 002). The infection rates of hookworm,Ascaris lumbricoides and Trichu?ris trichura were 18.96%(190 cases),1.70%(17 cases)and 0.90%(9 cases)respectively. The percentages of people with light infection of hookworm,A. lumbricoides and T. trichura were 97.37%(185/190),88.24%(15/17)and 100%(9/9)respec?tively. No infection of E. vermicularis was found. Fifteen soil samples were tested,and no hookworm was found in the soil. Con?clusion The infection rate of soil?transmitted nematode in Xiding Township,Menghai County is high,but the infectiosity is light. The control and monitoring of soil?transmitted nematodosis should be strengthened in this area.

Objective To investigate the expression of CD27-CD70 co-stimulatory pathway in peripheral circulation and intestinal mucosa of patients with inflammatory bowel disease, and to find the difference between the expression of CD27-CD70 in patients with inflammatory bowel disease and in healthy controls. Methods A total of 62 patients with Crohn's disease, 64 patients with ulcerative colitis and 56 healthy controls were enrolled. Enzyme-linked immunosorbent assay was applied to evaluate plasma CD27-CD70 protein expression in patients with inflammatory bowel disease and healthy controls. SYBR-green real time PCR was applied to access CD27-CD70 mRNA expression in peripheral blood mononuclear cells in patients with inflammatory bowel disease and healthy controls.And CD27-CD70 protein expression in intestinal mucosa was determined by immunohitochemistry.Results Plasma levels of CD27 (P=0. 025) and CD70 (P=0. 000) were significantly higher in patients with Crohn's disease than in healthy controls. However, CD27 (r= 0. 055, P= 0. 673) and CD70 (r= 0. 024, P = 0. 852) were not significantly associated with endoscopic disease activity in patients with Crohn's disease. Similarly, CD27 (P=0. 001) and CD70 (P=0. 000) were significantly higher in patients with ulcerative colitis than in healthy controls. And CD27 (r=0. 077, P=0. 547)and CDT0 (r=0.021, P=0. 869) were not significantly associated with endoscopic disease activity in patients with ulcerative colitis. Moreover, CD27 and CD70 mRNA expression in peripheral blood mononuclear cells were significantly higher in patients with Crohn's disease and ulcerative colitis than in healthy controls (all P=0. 000), and immunostaining indicated that CD27 and CD70 expression in intestinal mucosa were significantly higher in patients with Crohn's disease and ulcerative colitis than in healthy controls (all P=0. 000). Conclusions CD27-CD70 pathway activated in plasma, peripheral blood mononuclear cells and intestinal mucosa of patients with inflammatory bowel disease. However,plasma levels of CD27 and CD70 can not reflect endoscopic disease activity.

Temporomandibular joint disorder (TMD) is one of the common diseases in stomatology caused by a variety of factors, with a high incidence rate, especially among the young people with great pressure, and difficult to treat this disease. it was easy to relapse directly affects the physical and mental health and quality of life of the patients. Psychological factors had been proved to be one of the causes of temporomandibular joint disorder, and cognitive behavioral therapy was a form of psychological therapy that has been applied to a variety of problems, including mental illnesses such as depression, anxiety, and physical symptoms like pain. Cognitive behavioral therapy (CBT) was also used in stomatology department. This paper reviewed the origin, concept formation, theory formation, characteristics and application of CBT in TMJ disorders, in order to provide more evidence for clinical practice and reduce pain for patients.
