Objective To observe the clinical efficacy of the combination of western medicine with acupuncture for treatment of polycystic ovary syndrome (PCOS) of infertility.Methods Totally 120 PCOS patients were randomly divided into western medicine group and acupuncture group, 60 cases in each group. All patients took Diane-35, and with whom resistant to insulin were added with Metformin. At the meantime patients increased the amount of exercise with adjustment and control of everyday diet. After three periods, the western medicine group used the method of Clomifene Citrate with Chorionic Gonadotropin to help ovulation induction. The acupuncture group used the method of acupoint selection including invigorating spleen and kidney with adjusting qi and blood to promote ovulation. The level of FSH, LH, FINS, E2 and T of the two groups were observed before and after treatment.Results After treatment, the levels of T, FINS, LH and BMI in the two groups decreased, with statistical significance (P<0.05). The levels of T and BMI in the acupuncture group were lower than the western medicine group after the treatment, with statistical significance (P<0.05). The total efficiency, gestation number, number of high-quality follicle, and basal body temperature of acupuncture group were all higher than the western medicine group, with statistical significance (P<0.05).Conclusion The combination of western medicine with acupuncture for treatment of PCOS of infertility has confirmed efficacy.

Objective To detect the expression of miRNA -34a in normal cervical,low grade cervical intra-epithelial neoplasia and high grade cervical intraepithelial neoplasia,to explore its clinical significance.Methods The expression levels of miRNA -34a in 82 cases of low grade cervical intraepithelial neoplasia (CINⅠ,CIN L group),87 cases of high grade cervical intraepithelial neoplasia (CINⅡ -Ⅲ,CIN H group) and 60 cases of normal cervical tissues (control group) in tissue specimens and serum were examined by real -time PCR(RT -PCR). Results The relative expression levels of miRNA -34a in tissues and serum of CIN H group were (0.584 ± 0.288),(0.528 ±0.299),which of CIN L group were (0.903 ±0.252),(0.847 ±0.279),which of the control group were (0.960 ±0.212),(0.908 ±0.223).The miRNA -34a level of CIN H group in tissues and serum were lower than CIN L group and control group,there was significant difference( Ptissues =0.001,Pserum =0.003).The miRNA -34a level in tissue and serum had no significant difference between the CINL group and control group(P >0.05).The expression level of serum miRNA -34a was positively related with the level of the tissues(r =0.907,P <0.01).Conclusion The expression level of miRNA -34a in high grade CIN was significantly decreased,which indi-cated that miRNA -34a play an important role in the prognosis of CIN and the transformation of cervical cancer,and it has certain clinical value for the diagnosis and treatment of CIN.

OBJECTIVETo evaluate the quality status of rubella virus IgM diagnostic kits by national supervising sampling.

METHODSUsing legal inspection combining with exploratory study, the positive and negative coincidence rate, detection limit and repeatability of kits were verified.

RESULTSThe results showed that 15 of 16 batches of kits were qualified using legal inspection, and the passing rate was 93.8%. The unqualified item was negative coincidence rate. In exploratory study, only 11 batches (68.8%) complied with industry standard. The unqualified items were negative coincidence rate, detection limit and repeatability.

CONCLUSIONAt present, rubella virus IgM diagnostic Kits have some quality problems in the market. It is recommended that we adopt industry standard and national reference panel in the registration inspection for the future, which will prompt enterprises to improve quality.

Objective To explore the influence of different delineators and different delineating time on target determination of the whole breast and to explore intrafraction and interaction target displacements of the breast on moderate deep inspiration breathing hold (mDIBH) assisted by active breathing control (ABC) after breast conservative surgery. Methods Twenty patients received primary CT-simulation assisted by ABC to get five sets of CT image on the three breathing condition which included one set from free breath ( FB), two sets from mDIBH and two sets from deep expiration breathing control (DEBH). After radiotherapy with ten to fifteen fractions, the repeat CT-simulation was carried out to get the same five sets of CT image as the primary CT-simulation. The whole breast target were delineated at different time by the same delineator and delineated respectively by five delineators on the first set of CT images got with mDIBH from the primary CT-simulation,and to compare the influence of delineator and delineating time on the whole breast target. The total silver clips in the cavity were marked respectively on the two sets of CT images got with mDIBH from the primary CT-simulation, and to compare the intrafraction displacement of geometric body structured by the total of silver clips. The two ribs near the isocentric plane of the breast target were delineated respectively on two sets of the mDIBH CT image from the primary CT-simulation and on one set of the mDIBH CT image from the repeat CT-simulation, and comparing the movement of the point of interest (POI) of the ribs delineated to get the value of intrafraction and interfraction thoracic expansion. Results There was not statistically significant between the four volumes of whole breast targets delineated by the same delineator at different time, but with statistics significant between the volumes of whole breast target delineated by the different delineators(F = 19.681, P = 0.000). There was not statistically significant between the intrafraction displacements of the POI of the geometric body at each direction, and with no statistically significant between intrafraction displacements of the POI of the ribs delineated on the same mDIBH condition. There was not statistically significant between the interfraction displacements of the POI of the ribs delineated. Conclusions The influence of different delineators on the whole breast target is statistically significant. The difference of displacement of the breast target with the same mDIBH eondition assisted by ABC at the different direction is not statistically significant.

Objective To discuss the effect of Dickkopf-1 (DKK-1) on Wnt singal pathway during the differentiation of osteoblast in vitro.Methods The osteoblasts were obtained from the new rats and cultured in vitro.The 3 passages were divided into control group and DKK-1 group.The cells were cultured in DKK-1 and normal saline for morphogical detection,ALP activity detection and osteoblasts stained at 1 st,6th,12th,21st day.The Wnt was detected by RT-PCR.Results After cultured by the DKK-1 in vitro,the ALP and mineralization of osterblasts staining were prlonged with culture time.Compared with control group,the expression of Wnt was significantly reduced at the 21st day after induction (t =0.278,P ＜ 0.05).Conclusion DKK-1 can regulate the expression of Wnt during osteoblast differentiation,suggests that Wnt may be involved in osteoblast differentiation and can affect bone remodeling process.

Objective To explore the relationship between Stathmin-1 and human papilloma viruse (HPV) persistent infection after conization of uterine cervix, and to show the clinical significance to recurrent of cervical intraepithelial neoplasia (CIN). Methods One hundred and six patients who were treated with conization of uterine cervix for CIN 2-3 grades were enrolled. Thirty-six recurrent patients were enrolled in recurrence group, and the others were enrolled in control group. The expression of Stathmin-1 in primary CIN tissues in two groups was detected by immunohistochemistry. The HPV infection was detected by HPV-DNA test. The relationship of HPV persistent infection and recurrence was analyzed. Results The positive expression rate of HPV persistent infection and HPV persistent infection rate in recurrence group were 88.89%(32/36), 83.33%(30/36), in control group were 34.29%(24/70) and 22.86%(16/70), and there were significant difference (P <0.01). Forty-two patients had HPV persistent infection in 56 patients with stathmin-1 positive expression, and 4 patients had HPV persistent infection in 46 patients Stathmin-1 negative expression. There was positive correlation (r=0.97, P<0.01). The type of HPV persistent infection in two groups was no significant difference (P >0.05). Conclusions Stathmin-1 positive expression is related to HPV persistent infection. The two factors can affect the prognosis of high-grade CIN, and can provide new cues and theory basis for the prevention of recurrence.

OBJECTIVETo investigate psychological stress and influence factors on the mine emergency rescue personnel.

METHOD564 mine emergency rescue personnel from a rescue group were select as subjects, and 60 designers from a steel design institute were as controls. Self-made questionnaire and general job stress questionnaire were used to investigate the basic information, rescue history, psychosomatic symptoms, depression symptoms, daily job stress and negative emotions of emergency rescue personnel. SPSS17.0 software was used to analysis the psychological stress on the mine rescue personnel and its influence factors.

RESULTSThe detection rate (41.94%) of depression symptoms in rescue team was higher than that of controls (24.90%). The score of daily job stress was higher than that of logistical support. The older age group with higher negative emotional and daily job stress than the younger. The highest negative emotion was in age group of more than 40 years old. The highest score of daily job stress was in ≤30 years old. The score of depression and psychosomatic symptoms were higher than those of the college and the above. The scores of depression in group of duration of rescue <10 years was higher than that of duration≥10 years. The score of daily job stress is the lowest in rescue for 1 to 2 times per year and the highest in group of simulation training once a week. The score of daily job stress and depressive symptoms were getting higher with the extension of combat duty time. Age, hours of combat duty, training times a week, education and life events were the main affecting fectors on mental health of mine rescuers.

CONCLUSIONSMine rescuers have more psychological stress than generic population. The psychological stress of the mine crew is related to age, education, life events, training and combat readiness duty time.
