Objectives:To explore the effects of love resources and the lovers'resources equivalence on their romantic relationship quality.Methods:A sample of 203 pairs of lovers from 5 provinces and municipalities were selected(aged from 15 to 29).They were assessed with the Evaluation Form of Love Resources for Individual(EFL-RI)and the Scale of Relationship Perception Index for Unmarried People(RPUS)for the evaluation of the relation-ship between the love resource equivalence and the romantic relationship quality.The EFLRI was used to quantify the 12 individual love resources (the appearance of individual,stature,sexual health,health,personality,mental health,sense of responsibility,capacity,professional/occupation,education background,earning and family back-ground).The results included self-evaluation and peer-evaluation.Results:Self-assessment of responsibility between lovers and D-value of mental health were negatively correlated with the reported RPUS scores of both sides (r =-0.20 --0.33,Ps <0.05).The D-values of earning and family background were positively correlated with the re-ported RPUS scores of both sides (r =0.14 -0.25,Ps <0.05).Lovers'peer-evaluation of sexual health scores and the D-values of responsibility were negatively correlated with the reported RPUS scores of both sides (r =-0.25 --0.38,Ps <0.01.The D-values of professional/occupation and family background were positively correlated with the reported RPUS scores of males (r =0.20,0.18,Ps <0.05).Love resources(responsibility,sexual health,educa-tion background of males;appearance,personality,capacity of females )had positive predictability to males'repor-ted RPUS scores (β=0.14 -0.34),love resources(responsibility,appearance,personality,capacity,health of males and health,education background of females )had positive predictability to females'reported RPUS scores (β=0.14 -0.27).Conclusion:It suggests that the equivalence of responsibility resource has a positive influence for the quality of love relationship.The equivalence of family background resource has a negative effect for the quality of love relationship.

ObjectiveTo evaluate the influence of laparoscopic operation on pH value, phagocytic function of neutrophil, immunoadhesion activity of RBC CR 1 (complement receptor typeⅠ) in abdominal cavity. Methods Determination of the pH value, phagocytic function of neutrophil, immunoadhesion of RBC CR 1 in abdominal exudatives during laparoscopic procedures was undertaken and results were compared with the relative indexes detected in peripheral vein blood. Results The average pH value was 7.41, the percentage of the phagocyte was 74.6%, phagocytic index 55.7, and immunoadhesion activity of RBC CR 1 was 58% in blood during laparoscopic operation. While the average pH value was 7.14, the percentage of the phagocyte 65.6%, phagocytic index 47.6,and immunoadhesion activity of RBC CR 1 50% in the abdominal exudatives. Conclusion Compared with the peripheral vein blood indexes, the intraabdominal pH value, phagocytic function of neutrophil and immunoadhesion activity of RBC CR 1 decreased significantly during laparoscopic operation. The intraabdominal inflammation may diffuse with the effect of CO 2 pneumoperitoneum when patients with serious inflammation receive laparoscopic operation.

Objective To compare the clinical effects of small splint fixation after closed manipulative reduction with plaster external fixation in the treatment of elderly type C Colles fractures.Methods Totally 96 elderly patients with type C Colles fractures were randomly divided into two groups, 48 patients in each group. Both groups were treated with closed manipulative reduction. The fractures were externally fixed with splint in the treatment group, and those were externally fixed with pipe plaster in the control group. The figure of radius length, palmar tilt and ulnar deviation were detected respectively in pre-reduction, the same day with reduction, and the day when external fixation was removed (6th week), in order to evaluated the drop of anatomical position. The therapeutic effects were evaluated according to Gartland-Werley wrist score when external fixation was taken off after 6 months.Results In both groups, figures of radius length, palmar tilt and ulnar deviation evidently increased in the day after reduction and the day of external fixation removal, compared with pre-reduction (P<0.05). Compared with the day after reduction, the radius length, palmar tilt and ulnar deviation of the day of external fixation removal all dropped in both groups (P<0.05). But the drop degree in control group was significantly higher than treatment group (P<0.05). For the joint function, 9 cases for excellent, 26 for good, 6 for fair, and 4 for bad in the therapy group. The excellent and good rate was 77.8% (35/45). In the control group, 4 cases for excellent, 22 for good, 10 for fair and 9 for bad. The excellent and good rate was 57.8% (26/45). The curative effect of treatment group was remarkably superior to control group (P<0.05).Conclusion Closed manipulative reduction combined with splint external fixation is more effective than pipe plaster in treatment of elderly type C Colles fractures.

Objective To observe the clinical efficacy of Huoxue Bitong Plaster on lumbar osteoarthritis with blood stasis and cold-dampness blocking collaterals syndrome. Methods Totally 120 patients were randomly divided into treatment group (60 cases) and control group (60 cases). Huoxue Bitong Plaster was applied externally in the treatment group, while Goupigao Plaster was used externally in the control group, once a day, for two weeks. The clinical efficacy was evaluated by observing TCM symptom scores, VAS, Oswestry dability index (ODI), and onset time in both groups before and after treatment. Results The total effective rate was 86.67%(52/60) in treatment group, and 85.00% (51/60) in the control group, with no statistical significance (P>0.05). TCM symptom scores of both groups decreased after treatment (P<0.05). For the effect of relieving back pain and morning stiffness, the treatment group was superior to control group (P<0.05). For the effect of relieving waist heaviness, the control group was better than the treatment group (P<0.05). Besides, VAS and ODI of the treatment group were lower than the control group after treatment (P<0.05). The onset time of lightening back pain, morning stiffness in the treatment group was quicker than control group (P<0.05). For waist heaviness, the onset time in control group was quicker than treatment group (P<0.05). Conclusion Huoxue Bitong Plaster has good efficacy for lumbar osteoarthritis with blood stasis and cold-dampness blocking collaterals syndrome.

Objective The inhibitor of differentiation 3 (Id3) is an important transcriptional regulation factor, which participates in tumorigenesis, cell proliferation, and cell apoptosis.β-catenin, as a central molecule of the Wnt signaling pathway, is critical for tumor development.This study aimed to evaluate the expressions of these two molecules and the regulatory effect of Id3 on β-catenin in different tumor cells.Methods Total RNA was extracted using the Trizol Reagent.The relative mRNA expression levels of Id3 and β-catenin in tumor cells were detected by quantitative real-timePCR(qRT-PCR).The recombinant eukaryotic expression vector pEGFP/Id3 with the human Id3 gene was transfected into A549, A549/ DDP and SW-480 cells using the non-liposome-mediated method.The protein expressions of Id3 and β-catenin were determined by Western blot.Results The expression of Id3 was significantly lower in the colorectal cancer cell lines SW-480 and HT-29 than in A549 and other tumor cells (P<0.05), but remarkably higher in nasopharyngeal carcinoma CNE and 5-8F cells than in other tumor cells (P<0.05).The expression of β-catenin was the highest in SW-480in comparison withother malignant tumor cells(P<0.05), and the second highest was in gastric cancer AGS and colorectal cancer HT-29 cell lines, but low in H446, A549, SPC-A-1, A549/DDP, and SK-MES-1 cell lines and extremely low or almost absent in CNE and 5-8F cells (P<0.05).After transfected with pEGFP/Id3, the cells showed a decreased volume, wrinkled membrane and absent refraction under the fluorescence microscope, which, however, were not observed in most of the cells transfected with the empty vector pEGFP.Compared with the control, the Id3/pEGFP group showed remarkably increased expressions of Id3 mRNA in the A549, A549/DDI, and SW-480 cells (1.24±0.12 vs 193.12±2.80, 1.09±0.11 vs 188.30±2.60, and 0.92±0.29 vs 19.08±0.59, P<0.01), and the expression of β-catenin was significantly down-regulated in the transfected SW-480 cells with an overexpression of Id3 (0.98±0.05 vs 0.32±0.03, P<0.01), but exhibited no statistically significant differences from those in the transfected A549 and A549/DDP cells (0.98±0.07 vs 1.04±0.08 and 0.98±0.05 vs 0.32±0.03, P>0.05).Western blot showed the same results.Conclusion The expression levels of Id3 and β-catenin vary in different tumor cell lines.Anabnormally high level of β-catenin is an important risk factor for colorectal cancer, and the down-regulatedexpression of β-catenin after eogenous transfection of Id3 may provide some new ideas for target gene therapies of colorectal cancer.

BACKGROUND:Nickel-titanium memory-shape compression anastomosis clip (Ni-Ti CAC) has been used in gastrointestinal anastomosis, but its efficacy and safety still remain controversial.OBJECTIVE:To evaluate the efficacy and safety of Ni-Ti CAC in gastrointestinal anastomosis.METHODS:A computer-based online research of PubMed, EMbase, Cochrane Library, CBM, CNKI, and VIP databases was performed for articles published before January 15th, 2017 using the keywords of nickel-titanium, compression anastomosis clip, anastomosis, gastric, jejunum, ileum, small intestine, colon, rectum, and large intestine in English and Chinese, respectively. The randomized controled trials about Ni-Ti CACversus conventional methods for gastrointestinal anastomosis were included. Meta-analysis of the anastomosis time, time of exsufflation, and hospitalization time was performed, and sequential analysis was conducted on TSA v0.9 software.RESULTS AND CONCLUSION:A total of 18 eligible randomized controlled trials were enroled, involving 1860 patients. Ni-Ti CAC could reduce the anastomosis time [MD=-3.83, 95%CI(-6.48,-1.19),P=0.004] and time of exsufflation [MD=-0.14, 95%CI(-0.22,-0.05),P=0.002], but there was no significant difference in the hospitalization time [MD=-0.83, 95%CI(-1.82, 0.16), P=0.10]. The quality was ranked as low level based on GRADE system. The time of exsufflation of Ni-Ti CAC was superior to that of conventional method, which was confirmed by sequential analysis. One case of death was reported and incision infection was the most common adverse effects; additionaly, pulmonary embolism and abdominal pain occurred. To conclude, Ni-Ti CAC can facilitate gastrointestinal anastomosis, accelerate the time of exsufflation, and holds a good safety. However, more multicenter and high-quality randomized controlled trials are needed.

Objective To evaluate the effect of dexmedetomidine on the expression of Semaphorin 7A during lung ischemia-reperfusion (I/R) in rats.Methods Thirty healthy clean-grade adult male Sprague-Dawley rats,aged 8-12 weeks,weighing 200-240 g,were divided into 3 groups (n=10 each) using a random number table method:sham operation group (S group),I/R group and dexmedetomidine group (D group).Only sternotomy was performed,and the left hilum of lung was not clamped in S group.The model of lung I/R injury was established by clamping the left hilum of lung for 45 min followed by 120 min of reperfusion in I/R group.Dexmedetomidine 50 μg/kg was intraperitoneally injected at 30 min before ischemia,and then the model was established in D group.The rats were sacrificed at the end of reperfusion,and the lungs were removed for examination of the pathological changes (using haematoxylin and eosin staining) which were scored and for determination of the wet to dry weight ratio (W/D ratio),expression of Semaphorin 7A protein and mRNA (by Western blot or real-time polymerase chain reaction),and contents of tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) in lung tissues (by enzyme-linked immunosorbent assay).Results Compared with S group,W/D ratio and pathological scores were significantly increased,the expression of Semaphorin 7A protein and mRNA was up-regulated,and the contents of TNF-α and IL-1β were increased in I/R and D groups (P＜0.05).Compared with I/R group,W/D ratio and pathological scores were significantly decreased,the expression of Semaphorin 7A protein and mRNA was down-regulated,and the contents of TNF-α and IL-1 β were decreased in D group (P＜0.05).Conclusion The mechanism by which dexmedetomidine reduces lung I/R injury may be related to down-regulating Semaphorin 7A expression,thus inhibiting inflammatory responses of rats.
