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: 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 measure the expression of granulocyte colony-stimulating factor receptor (G-CSFR) in human melanocytes and to evaluate the biologic effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on human melanocytes.Methods Melanocytes were obtained from circumcision specimens of healthy males,and neutrophils were isolated from heparin-andcoagulated peripheral blood of healthy human followed by a primary culture.Then,the melanocytes in third passage were cultured with or without the presence of various concentrations (200,400,600,800 μg/L) of rhG-CSF for 72 hours.The growth and morphology of melanocytes were observed.Flow cytometry was performed to detect the expression of G-CSFR in untreated human melanocytes,neutrophils and erythroleukemia cells (HEL 92.1.7).Western blot and reverse transcription PCR (RT-PCR) were carried out to measure the expression of G-CSFR protein and mRNA respectively in the neutrophils,HEL 92.1.7 cells,treated or untreated human melanocytes.Methyl thiazolyl tetrazolium (MTT) assay was performed to evaluate the proliferation,and dopa-oxidation assay to estimate the tyrosinase activity,of treated melanocytes.Results The expression rate of G-CSFR was 76.81％ ± 10.70％ in human melanocytes,significantly higher than that in the HEL 92.1.7 cells (2.53％ ± 1.54％,P ＜ 0.01 ),but lower than that in the neutrophils (85.76％ ± 15.71％,P ＜ 0.05).Both G-CSFR protein and mRNA were expressed in melanocytes,and there was no significant differences in the expression level of G-CSFR protein and mRNA among melanocytes treated with different concentrations of rhG-CSF (both P ＞ 0.05).The expression levels of G-CSFR protein and mRNA in the melanecytes were significantly higher than those in the HEL 92.1.7 cells (both P ＜ 0.01 ),but lower than those in the neutrophils (P ＜ 0.05 or ＜ 0.01 ).rhG-CSF at 200-800 μg/L displayed a significantly promotive effect on the proliferation of melanocytes (P ＜ 0.01 or ＜ 0.05 ),and the effect was in a dose-dependent manner when rhG-CSF ranged from 200 to 600 μg/L (P ＜ 0.01 ).The rhG-CSF at 600 μg/L and 12-O-tetradecanoyl-phorbol-13-acetate (TPA) at 20 μg/L showed an equivalent effect on the proliferation of melanocytes (164.04％ ± 13.0％ vs.165.62％ ± 10.6％,P ＞ 0.05).However,rhG-CSF from 200 to 800 μg/L had no significant impact on the tyrosinase activity of melanocytes (all P ＞ 0.05 ).Conclusions G-CSFR is expressed in human melanocytes. rhG-CSF can promote the proliferation of cultured human melanocytes,but has no obvious influence on the tyrosinase activity of melanocytes.

OBJECTIVETo explore the mechanism of electroacupuncture at Zusanli (ST 36) on regulation of intestinal inflammatory reaction in rats with acute pancreatitis.

METHODSFifty-four SD rats were randomly divided into a severe acute pancreatitis (SAP) group, an electroacupuncture (EA) group and a sham-operation (SO) group, 18 cases in each group. 3.5% sodium cholate was used to made SAP model by retrograde injecting in cholangiopancreatic duct. After the success of model making, the EA group was treated with EA at bilateral Zusanli (ST 36) for 30 min. The SO group and the SAP group were fixed at the same time for 30 min without treatment. All the rats were killed at 3 h, 6 h and 12 h after modeling in batches. The pathological changes of pancreatic tissue and intestinal epithelium were observed, and the expression of small intestinal occludin protein and nuclear factor kappa-B (NF-kappaB) were detected by immunohistochemical SP method.

RESULTSThe pathologic score and the expression of small intestinal NF-kappaB p65 at 3 h, 6 h and 12 h after modeling in the EA group and the SO group were significantly lower than those in the SAP group (all P < 0.05), and the expression of small intestinal occludin protein in the EA group and the SO group were significantly higher than that in the SAP group (all P < 0.05).

CONCLUSIONElectroacupuncture at Zusanli (ST 36) can alleviate pancreatic injury by reducing the expression of NF-kappaB p65 and enhancing the expression of occludin protein in the intestinal epithelium in the SAP model rats.

Objective To investigate the endoluminal ultrasonographie characteristics of adenoearcinoma and mucous adenocareinoma of the rectum. Methods The ultrasonographie characteristics of thirty eases of advanced adenoeareinoma of the rectum and twenty-eight eases of rectal mucous adenoearcinoma were analyzed retrospectively in comparison with their eorresponding pathologic images. Results In advanced adenocareinoma of the rectum, 28 eases manifested rough endoluminal surface, of which 19 marked by thickened changes without arrangement of layers, 10 had indistinct arrangement of layers in some areas and one had clear arrangement of layers. In the deepest margin of infiltration, 17 eases manifested sentus, homed or knot-like protuberance, while 5 marked by wavy margins, and 8 cases had clear and fiat margins. In 25 eases of rectal mucous adenocareinoma, 20 manifested smooth endoluminal surface. With regard to infiltration of tumors to rectal wall, 6 cases manifested clear arrangement of layers, while 13 had clear arrangement of layers in part and 6 had no clear arrangement. In the deepest part of infiltration, 8 eases manifested slippery and fiat margins and 10 manifested wavy margins and 7 had a few sentus, homed or knot-like protuberance locally. According to ultrasonic results of the depth of infiltration to rectal wall in comparison with pathologic findings, 25 eases were diagnosed accurately, while in two cases the diagnosis was too shallow and in three eases it was too deep. In rectal mucous adenocarcinoma, 10 cases got correct diagnosis and 14 were diagnosed superficially and one got too deep. The accuracy of ultrasonic diagnosis on rectal mueoas adenoearcinoma was apparently lower than that of adenoeareinoma and most of the misdiagnosis were too superfieiai. Conclusion There are different ultrasonographie characteristics of rectal adenoeareinoma and rectal mucous adenoeareinoma, which can be helpful for the typing of rectal carcinoma and avoiding excessively superficial misdiagnosis.
