Objective To analyse the efficacy of methotrexate combined with mifepristone in treatment of 130 cases heterotopic pregnancy. Methods 130 cases heterotopic pregnancy from January 2014 to December 2014 in obstetrics and gynecology department of First Affiliated Hospital of Liaoning Medical University were divided into observation group and control group, randomly, 65 cases in each group.Patients in control group were treated with 1 mg/kg methotrexate of intramuscular injection, one time per day; patients in observation group were treated with mifepristone of oral, one time per day, 75mg per time on the basis of control group.The serum β-subunit of human chorionic gonadotropin (β-hCG), normal pregnancy rate, size of enclosed mass, rate of treatment success and adverse reactions in two groups were compared.Results The recovery time of serum β-HCG in observation group was shorter than that in control group ( P <0.05 ) , and normal pregnancy rate in observation group was higher than that in control group (P<0.05).After 7 and 14 days’ treatment, size of enclosed mass in observation group was smaller than that in control group (P<0.05).After two months’ treatment, the efficacy in observation group was higher than that in control group (92.31%vs.61.54%;χ2 =17.33,P<0.05).There was no significant difference in adverse reactions rate between two groups (χ2 =0.34,P>0.05).Conclusion Methotrexate combined with mifepristone could improve the clinical efficacy which is a safe therapy with few adverse reactions.

BACKGROUNDTo evaluate the quality of life (QoL) of lung cancer patients and to investigate the differences in QoL with respect to social and medical characteristics.

METHODSStructured questionnaires (EORTC QLQ-C30 and QLQ-LC13) were used in 106 consecutive lung cancer patients for data collection during January 1, 2002 to December 31, 2002. The t test and one-way analysis of variance (ANOVA) were used to compare the differences in QoL at a 5% level of significance.

RESULTSThe QoL of lung cancer patients were worse than reference value. The QoL of young, male and married patient groups was better than that in old, female and single groups. The QoL in patients with lower education or income was worse than that in patients with high education and income. Small cell lung cancer patients showed poorer QoL than non-small cell lung cancer patients did. The locally advanced or metastatic patients had worse QoL. All the kinds of treatments could worsen the QoL, however, the patients receiving surgical treatment had best QoL.

CONCLUSIONSThe results suggest that the establishment of QoL judgment standard in Chinese lung cancer patients might be useful for clinicians, researchers and policy-makers.

Background::Joint dislocations significantly impact public health. However, a comprehensive study on the incidence, distribution, and risk factors for joint dislocations in China is lacking. We conducted the China National Joint Dislocation Study, which is a part of the China National Fracture Study conducted to obtain the national incidence and risk factors for traumatic fractures, and to investigate the incidence and risk factors for joint dislocations.Methods::For this national retrospective epidemiological study, 512,187 participants were recruited using stratified random sampling and probability-proportional-to-size method from January 19 to May 16, 2015. Participants who sustained joint dislocations of the trunk, arms, or legs (skull, sternum, and ribs being excluded) in 2014 were personally interviewed to obtain data on age, educational background, ethnic origin, occupation, geographic region, and urbanization degree. The joint-dislocation incidence was calculated based on age, sex, body site, and demographic factors. The risk factors for different groups were examined using multiple logistic regression.Results::One hundred and nineteen participants sustained 121 joint dislocations in 2014. The population-weighted incidence rate of joint dislocations of the trunk, arms, or legs was 0.22 (95% confidence interval [CI]: 0.16, 0.27) per 1000 population in 2014 (men, 0.27 [0.20, 0.34]; women, 0.16 [0.10, 0.23]). For all ages, previous dislocation history (male: OR 42.33, 95% confidence interval [CI]: 12.03–148.90; female: OR 54.43, 95% CI: 17.37–170.50) and alcohol consumption (male: OR 3.50, 95% CI: 1.49–8.22; female: OR 2.65, 95% CI: 1.08–6.50) were risk factors for joint dislocation. Sleeping less than 7 h/day was a risk factor for men. Compared with children, women aged ≥15 years (female 15–64 years: OR 0.16, 95% CI: 0.04–0.61; female ≥65 years: OR 0.06, 95% CI: 0.01–0.41) were less likely to sustain joint dislocations. Women with more than three children were at higher dislocation risk than women without children (OR 6.92, 95% CI: 1.18–40.78).Conclusions::The up-to-date data on joint dislocation incidence, distribution, and risk factors can be used as a reference for national healthcare, prevention, and management in China. Specific strategies for decreasing alcohol consumption and encouraging adequate sleeping hours should be developed to prevent or reduce dislocation incidents.Trial Registration::Chinese Clinical Trial Registry, ChiCTR-EPR-15005878.

Objective:To investigate the mechanism of immunomodulatory effects of umbilical cord mesenchymal stem cells(UC-MSCs)modified by miR-125b-5p on systemic lupus erythematosus(SLE).Methods:The expression level of miR-125b-5p was detected by real-time fluorescence quantitative PCR in UC-MSCs and peripheral blood mononuclear cells(PBMCs)from SLE patients and health checkers.Annexin V-FITC/PI apoptosis detection kit was used to detect the effect of miR-125b-5p on apoptosis of UC-MSCs.MRL/lpr mice in each group were injected with UC-MSCs via tail vein,and T-lymphocyte subsets in the spleen of the MRL/lpr mice were detected by flow cytometry after 5 weeks.The expression levels of interleukin(IL)-4 and IL-17A in serum of MRL/lpr mice were detected by ELISA.Hematoxylin-eosin staining was used to observe the pathological manifestations of the lungs and kidneys of the MRL/lpr mice.Results:miR-125b-5p was significantly down-regulated in PBMCs of SLE patients compared with healthy controls(P＜0.01).Compared with the UC-MSCs group,the expression of miR-125b-5p in UC-MSCs modified by miR-125b-5p group was increased(P＜0.01).The survival rate of UC-MSCs was significantly increased by miR-125b-5p(P＜0.01).Compared with the untreated group of MRL/lpr mice,the expression level of IL-4 in serum was increased(P＜0.05);the expression level of IL-17A was decreased(P＜0.05);the proportion of Th17 cells in the spleen of MRL/lpr mice was decreased(P＜0.05);the inflammatory cells infiltration and micro-thrombosis of lungs and kidneys of MRL/lpr mice were significantly reduced in the UC-MSCs modified by miR-125b-5p treatment group.Conclusion:UC-MSCs modified by miR-125b-5p have immunomodulatory effects on systemic lupus erythematosus.

OBJECTIVETo compare the clinical efficacy differences between acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method and traditional acupoint plaster therapy for senile osteoporosis (SOP).

METHODSWith randomized controlled blind design, 76 SOP patients with deficiency of liver and kidney syndrome were randomly divided into an observation group and a control group, 38 cases in each one. Based on oral administration of caltrate D, the patients in the observation group were treated with acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method at Yingu (KI 10), Taixi (KI 3), Dazhong (KI 4), Fuliu (KI 7) and Zhiyin (BL 67), while the patients in the control group were treated with traditional acupoint plaster therapy. Each plaster therapy lasted for 6 h, once a day; there was an interval of 2 d after consecutive 5-day treatment; 4 weeks were taken as one course, and totally 2 courses were given. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the pain and dysfunction before intervention, after 4 weeks and 8 weeks intervention. Osteoporosis symptom rating sale and quality of life questionnaire of the European foundation for Osteoporosis (QUALEFFO-41) were adopted to evaluate the TCM syndrome and quality of life before and after 8-week intervention.

RESULTSAll the outcomes were significantly improved after treatment in the two groups (<0.01,<0.05); after 4 weeks and 8 weeks of treatment, the VAS and ODI in the observation group were lower than those in the control group (all<0.05). Repeated ANOVA indicated the VAS and ODI were significant in group effect, time effect and interaction effect (all<0.01). Further comparison showed that VAS and ODI at later time points were lower than those in the early time points (all<0.01). After the treatment, the scores of TCM syndrome and QUALEFFO-41 in the observation group were lower than those in the control group (all<0.05). The effective rate was 85.7% (30/35) in the observation group, which was superior to the effective rate in the control group[74.3%(26/35),<0.05].

CONCLUSIONSThe acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method is superior to traditional acupoint plaster therapy in improving pain, dysfunction, TCM syndrome and quality of life in SOP patients; in addition, its clinical efficacy is significant.
