Objective: To investigate the incidence of menstrual disorder and the relationship between menstrual disorders and emotion, personality et al psychosocial factors in students. Methods: The study adopted stratified sampling method. 521 students were subjected to questionnaire of MHQ, STAI, CED-S and EPQ. Results: The rate of menstrual disorder was 44.7%. The average score of anxiety and depression in stress was significant higher than usual. The increasing trend of incidence of menstrual disorder accompanied with age, reaction degree of anxiety and depression and the level of trait anxiety in stress. Conclusion: The psychosocial factors such as emotion and personality play an important roles in the process of resulting in menstrual disorder. The doctors should pay more attention to strengthen the psychological interventions.

Objective:The study aimed at investigating the impact factors of FHA.Methods:The 33-pair subjects were both implemented laboratory check about ?-EP,ACTH,FSH,LH ,E2 in blood and questionnaire about Life Event Scale,EPQ and Coping Style.Results: As for the results of the single factor logistic,the impact factors were very complex.Perhaps the mechanism of FHA resulted from multi-factor interact.The main factors determining whether women suffered from FHA or not were life event,?-EP and withdrawing coping style.Conclusion:The psycholosocial factors of life events,personality and coping styles play important roles in the onset of FHA.

Objective:To investigate the influence of electroacupuncture on auditory evoked potential index (AAI) during propofol sedation.Methods: According to propofol effect site concentration, 24 patients for operation were randomly allocated to group 1 (1.0 μg/mL), group 2 (1.5 μg/mL) and group 3 (2.0 μg/mL). Propofol was administered intravenously, points Hegu (LI4) and Neiguan (PC6) were electro-acupunctured, and changes in AAI were recorded.Results:AAI significantly rose in all groups during the initial several minutes after electro-acupuncture and significantly fell in group 2 at 20 min after electro-acupuncture(P＜0.05).Conclusion:AAI can sensitively reflect pain response during electro-acupuncture and electro-acupuncture can strengthen propofol sedation at its medium concentration.

Objective: To observe the effects of electroacupuncture (EA) at Tianshu (ST25) on pro- and anti-inflammatory cytokines in sodium taurocholate-induced severe acute pancreatitis (SAP) in rats. Methods: Sixty-six male Sprague-Dawley rats were randomly divided into three groups: sham-operation group, SAP group and EA group. An SAP model was established by injecting 3.5% sodium taurocholate at a dose of 1 mL/kg through puncturing the pancreatic duct. In the EA group, EA at ST25 was performed with sparse-dense wave (2/100 Hz, 2 mA for 30 min) immediately after sodium taurocholate injection and 30 min before sacrifice. Rats were sacrificed at 3 (n=7), 6 (n=7) and 12 h (n=8) after operation. Levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-10 in serum were estimated by enzyme-linked immunosorbent assay. Pathological changes of pancreatic tissues were examined by hematoxylin and eosin staining and observed under a microscope and also scored. Results: The levels of serum TNF-α and IL-6 of SAP rats were significantly higher than those of sham-operation rats at 3, 6 and 12 h. The level of IL-10 in serum of SAP rats was significantly higher than that of sham-operation rats at 3 and 6 h (P<0.05). EA at ST25 down-regulated the levels of TNF-α and IL-6 in serum and up-regulated the level of IL-10 and the ratio of IL-10/TNF-α, also attenuated the morphological damages at 6 and 12 h (P<0.05) in rats with SAP. The pathological scores of pancreatic tissues in the EA group were significantly less than those in the SAP group at 6 and 12 h (P<0.05). Conclusion: EA at ST25 may have a therapeutic effect on rats with SAP by down-regulating the levels of TNF-α and IL-6 and up-regulating the level of IL-10 to re-establish the balance of pro- and anti-inflammatory cytokines, and to ameliorate the inflammatory response of SAP.

Objective To explore the effect of aerobic exercise on platelet function in elderly patients with hypertension and type 2 diabetes.Methods81 elderly patients with hypertension and type 2 diabetes were divided into the routine treatment group (group A, n=41) and regular exercise group (group B, n=40). All patients of two groups were treated with routine treatment. The exercise with moderate intensity was performed in the group B for 3 months besides routine treatment. The platelet membrane glycoprotein CD62P, CD61 (Ⅲa) were detected by flow cytometric analysis and platelet aggregating ratio was measured before and after regular aerobic exercise.ResultsAfter three months, the systolic blood pressures were 166±3.6 mm Hg (group A) and 152±3.5 mm Hg (group B); the diastolic blood pressures were 93±4.2 mm Hg (group A) and 83±4.3 mm Hg (group B); the contents of blood glucose were 7.4±2.4 mmol/L (group A) and 6.3±1.9 mmol/L (group B); the positive percents of platelet membrane glycoproten CD62P were 27.3±2.2% (group A) and 21.5±3.3% (group B), CD61(Ⅲa) were 26.3±2.3% (group A) and 20.2±2.9% (group B) and platelet aggregation rates were 78.4±4.5% (group A) and 69.7±5.4% (group B), there was a significant difference between two groups ( P<0.05～0.01).ConclusionRegular aerobic exercise can decrease the positive percent of platelet membrane glycoprotein and platelet aggregation rate in elderly patients with hypertension and type 2 diabetes.

OBJECTIVE: A case of half sibling was determined with multiple genetic markers, which could be potentially applied for determination of half sibling relationship from same father. METHODS: Half sibling relationship was detected by 39 autosomal STR genetic markers, 23 Y-chromosomal STR genetic markers and 12 X -chromosomal STR genetic markers among ZHAO -1, ZHAO -2, ZHAO -3, ZHAO -4, and ZHAO-5. RESULTS: According to autosomal STR, Y-STR and X-STR genotyping results, it was determined that ZHAO-4 (alleged half sibling) was unrelated with ZHAO-1 and ZHAO-2; however, ZHAO-3 (alleged half sibling), ZHAO-5 (alleged half sibling) shared same genetic profile with ZHAO-1, and ZHAO-2 from same father. CONCLUSION It is reliable to use multiple genetic markers and family gene reconstruction to determine half sibling relationship from same father, but it is difficult to determination by calculating half sibling index with ITO and discriminant functions.
