Objective To explore the effect of elemene on recurrent ovarian cancer with ascites and the impact on the life quality.Methods From August 2013 to July 2015,64 patients with recurrent ovarian cancer with ascites in Huangdao District Hospital of Traditional Chinese Medicine of Qingdao were collected. They were divided into control group (n =32)and observation group (n =32)by random number table. Patients in observation group were treated with elemene and cisplatin by intraperitoneal perfusion,and patients in control group were treated with cisplatin alone.The effects and life quality were compared between the two groups.Results There were 10 cases of complete response (CR),13 cases of partial response (PR),6 cases of stable disease (SD),3 cases of progressive disease (PD),71.88% of overall response rate (ORR)in the control group;and there were 19 cases of CR,9 cases of PR,3 cases of SD,1 case of PD,87.50% of ORR in the observation group,with significant difference (Z =-2.312,P =0.021).There were significant diffe-rences about the physical function (61.66 ±9.27 vs.51.66 ±15.73;t =-3.102,P =0.003),role function (59.89 ±13.29 vs.45.83 ±19.40;t =-3.383,P =0.001 ),emotional function (49.73 ±11.29 vs. 30.72 ±13.45;t =-6.120,P =0.000),cognitive function (62.50 ±13.39 vs.50.00 ±19.40;t =-3.000,P =0.004),total health status (54.69 ±10.99 vs.42.97 ±14.98;t =-3.568,P =0.001 ), symptoms of fatigue (38.53 ±13.23 vs.47.57 ±19.39;t =2.175,P =0.033),nausea and vomiting scores (19.27 ±4.77 vs.36.45 ±12.29;t =5.483,P =0.000)and symptoms of insomnia (23.95 ±10.77 vs. 38.54 ±11.46;t =2.216,P =0.030)between the observation and control groups.There were no differences about the social function (37.50 ±17.96 vs.36.97 ±16.79;t =-0.120,P =0.905),symptoms of pain (23.43 ±9.58 vs.22.92 ±9.19;t =-0.118,P =0.906),difficult breathing (19.79 ±6.49 vs.16.67 ± 5.74;t =-0.606,P =0.547),anorexia (63.54 ±25.90 vs.66.67 ±18.93;t =0.551,P =0.584),con-stipation (27.08 ±10.59 vs.23.96 ±9.14;t =-0.545,P =0.588),diarrhea (63.54 ±25.90 vs.66.67 ± 18.93;t =0.551,P =0.584)and economic hardship (60.41 ±21.03 vs.65.62 ±29.91;t =0.683,P =0.497)between the observation and control groups.Conclusion Elemene combined with cisplatin achieves the better efficacy on recurrent ovarian cancer with ascites by intraperitoneal perfusion,which has the potential to further improve the patient′s life quality,and deserves to be studied and promoted application.

ObjectiveTo evaluate the effect of compound oxymatrine injection combination with chemotherapy in patients with advanced ovarian carcinoma.MethodsEighty-six patients with advanced ovarian carcinoma were divided by random digits table method into observation group(43 cases) receiving compound oxymatrine injection plus chemotherapy(paclitaxel plus carboplatin) and control group (43cases) treated with chemotherapy(p aclitaxel plus carboplatin) alone.The change of white blood cell,adverse reaction and effect of the patients were observed.ResultsThe white blood cell of observation group after treatment was obviously higher than that of control group [ (4.7 ± 1.4) × 109/L vs.(3.2 ± 1.6) × 109/L,P ＜ 0.05 ].The rates of nausea and vomiting,transaminase elevating and kidney damage of observation group were obviously lower than those of control group[ 16.3％ (7/43),14.0％ (6/43),20.9％ (9/43) vs.34.9％(15/43),32.6％ (14/43),44.2％ ( 19/43 ),P ＜ 0.05 ].The complete remission rate of observation group was significantly higher than that of control group[55.8％(24/43) vs.27.9％(12/43),P ＜ 0.05].Conclusion Addition of compound oxymatrine injection to chemotherapy for patients with advanced ovarian carcinoma can effectively protect patients against the decreasing of the white blood cell and attenuate the side effects brought by chemotherapy.

ObjectiveTo investigate the effect of humanized nursing in ovarian cancer patients to improve treatment compliance and negative emotional state. Methods120 cases of ovarian cancer patients from October 2009 to October 2010 in our hospital were chosen as the research object.They were divided into the control group and the observation group according to randomization methods with 60 cases in each group.The control group patients were taken routine care.The patients in the observation group were taken humanized nursing on the basis of routine care.The treatment compliances during treatment were compared.The anxiety,depression scores for the two groups of patients before and after treatment were compared.Based on the three indicators,the effect of humanized nursing in ovarian cancer patients to improve treatment compliance and negative emotional state was evaluated.

ConclusionsHumanized nursing can improve the treatment compliance and negative mood of ovarian cancer patients effectively,it is conducive to the rehabilitation of patients,and is worthy of clinical application.

Objective To observe the effect of low frequency vibration (LFV) on bone metabolism, bone mass density (BMD), bone histomorphometric and biomechanical characterization in rats with secondary osteoporosis (OP) after spinal cord injury (SCI).MethodsSCI model was established with 50 SD rats by transecting spinal cord completely at the level of tenth thoracic vertebra, and the animals were randomly divided into 5 groups: SCI 6-week control group, SCI 12-week control group, vibration 6-week (Vi 6w) group, vibration 12-week (Vi 12w) group and vibration 6-12 week (Vi 6-12w) group. All rats of vibration groups accepted LFV (frequency=20 Hz, acceleration=0.15 g) with 10 minutes once, twice per day, and 6 days per week. The LFV was given from the forth day postoperation to the end of the sixth week in Vi 6w group, and to the end of twelfth week in Vi 12w group, while from the seventh week postoperation to the end of twelfth week in Vi 6-12w group. All animals were sacrificed when LFV test finishied. The serum alkaline phosphatase (ALP), bone glaprotein (BGP) and serum calcium (Ca2+)/BMD of femur and the fifth lumbar vertebra (L5)/bone histomorphometric characterization of tibia/bone biomechanical characterization of femur and L5 were measured.ResultsCompared with control groups, the serum Ca2+ and BMD of promixal femur improved significantly in rats of Vi 6w group ( P<0.05), while the maximal load of L5 increased significantly in rats of Vi 12 group ( P<0.05). There were no changes in rats of Vi 6-12w group ( P>0.05).ConclusionThe early treatment of LFV may improve the secondary OP of rats with SCI, but the effect is different in different sites of rats' body. The late treatment of LFV can't improve the secondary OP, but may keep rats with SCI from deteriorating.

BACKGROUND:In recent years, a lot of studies have reported the feasibility and efficacy of transplanting seed celsvia tissue-engineered cardiac patches into specific infarcted myocardial area, helping regeneration of damaged heart tissue and improving heart functions.
OBJECTIVE:To review the methods and strategies of fabricating tissue-engineered cardiac patches and to analyze the structure and functional characteristics of cardiac patches prepared by different methods.
METHODS: The first author retrieved relevant articles about the fabrication methods of tissue engineered cardiac patches by searching PubMed and Web of science data bases. The key words were “cardiac infarction, cel death”.
RESULTS AND CONCLUSION:The fabrication methods and strategies of tissue-engineered cardiac patches are as folows: (1) obtaining multi-layer cel sheets by overlapping monolayer cel sheets; (2) combing gelatin with cels to construct multi-layer cel sheets; (3) seeding cels on scaffolds; (4) homogeneous arrangement of cels. Recent studies about tissue-engineered cardiac patches have demonstrated that the biological activities of seed cels, such as retention, survival and paracrine effects, greatly influence the effect of cardiac patches on the repair and regeneration of infarcted myocardial tissues. Temperature-sensitive method is the most mature and wide-spread used constructing technique; besides, other strategies also successfuly improve the biological activities of seed cels to different extents, and they also increase the mechanical strength and thickness of cel sheets in order to have better operability. Tissue-engineered cardiac patches are usualy prepared by different combined strategies on purpose to obtain better biological and mechanical properties.

Objective To study the effects of continuous passive motion(CPM)on tissue blood oxygen saturation(StO2)in the edge of wound after anterior cruciate ligament(ACL)reconstruction in rabbits.Methods Twenty male New Zealand rabbits,aged 8 months,received an ACL reconstruction by using double semitendinous tendon autograft in the right hind leg.The rabbits were randomly divided into 2 groups postoperatively,namely Cage activity group(n=10)and CPM group(n=10),treated with cage activity and activity by rabbit knee joint continuous passive motion apparatus respectively.On the following day after operation,a near-infrared optical device and ODISseyTM Tissue Oximeter were applied to measure the changes of tissue oxygen saturation(StO2)in the edge of the wound in each cycle(with flexion of 30?-110?)and various CPM speeds(2.35?/s,3.2?/s,and 8?/s),and the optimal CPM range and speed was thus selected for analyzing the changes of StO2 in local tissues of wounds with various angles of CPM in knee joint before the operation and on the 2nd,4th,6th,8th,10th,and 14th postoperative days.Results There was a significant difference with regard to StO2 between CPM group and Cage activity group(P0.05),however,a significant difference was observed among different time points(before the operation,and 2,4,6,8,10,14 days after the operation)(P

Objective To explore the effect of low frequency vibration (LFV) on osteogenesis of bone marrow stromal cells (BMSCs) and OPG mRNA,RANKL mRNA expression.MethodsBMSCs from 10-week-old female SD rats were cultured and randomly divided into 2 groups:control group and vibration group.The BMSCs of vibration group was given LVF with 20 Hz,0.25 g,2 times/d,10 min/time for 7 days.The LFV was given from the eleventh day after BMSCs cultured.The osteogenesis and OPG mRNA,RANKL mRNA of all BMSCs in two group were tested at the end of LFV.ResultsCompared to the control groups,the BMSCs growth and proliferation improved in vibration group,but the alkaline phosphatase (ALP)activity and the number of mineral nodule did not changed significantly.The OPG mRNA elevated in vibration group,while the RANKL mRNA showed no change.ConclusionThe LFV may increase the growth and proliferation of BMSCs,which is attributed to the elevated OPG gene expression.The osteogenesis improved no significance,which may be associated with the too short vibration time.

[ ABSTRACT] AIM:To investigate the role of chronic psychological stress on periodontitis and the effects of hy-perbaric oxygen ( HBO) on periodontitis with psychological stress in rats.METHODS:Male special pathogen-free Wistar rats (n=80) were randomly divided into 4 groups:(1)normal control group;(2)experimental periodontitis group:the pe-riodontitis model was induced by wrapping 3/0 silk ligature inoculated with Porphyromonas gingivalis around the left maxil-lary second molar of the rats; ( 3 ) psychological stress stimulation group; ( 4 ) periodontitis model with stress stimulation group.Psychological stress was removed at the 9th week after ligature, and 4 rats from each experimental group were ran-domly chosen for HBO treatment.The rats were sacrificed at the 2nd, 4th, 8th and 10th weeks after ligature.The levels of blood glucose, adrenocorticotropic hormone ( ACTH) , corticosterone and adrenaline were measured as the stress markers. The histological changes of periodontal tissues were observed under microscope with HE staining.RESULTS:The levels of blood glucose, ACTH, corticosterone and adrenaline in psychological stress stimulation group and periodontitis with stress group were significantly higher than those in control group and experimental periodontitis group at the 2nd and 4th weeks af-ter ligature (P<0.05).The levels of the stress markers were significantly lower than those in untreated groups in the 10th week after HBO (P<0.01).The sites of gingival attachment were normal in control group and psychological stress stimu-lation group.Periodontal pocket, and periodontal attachment loss ( AL) were observed in experimental periodontitis group. The tissue damage was much heavier in periodontitis model with stress stimulation group as the furcation of tooth was ex-posed and the tissue damage was observed on both sides of the adjacent teeth.No significant difference of AL between psy-chological stress stimulation group and normal control group during the experiment was observed.The AL in periodontal model with stress stimulating group was significantly higher than that in experimental periodontitis group at the 2nd, 4th and 8th weeks (P<0.01).The level of AL was attenuated at the 10th week after HBO (P<0.01).No difference of histologi-cal change in periodontal tissues was observed between control group and psychological stress stimulation group.Severer in-flammatory changes and alveolar bone destruction were observed in periodontitis with stress group than those in experimental periodontitis group.The levels of inflammation reduced at the 10th week after HBO.CONCLUSION:Stress stimulation is one of the inducing factors of periodontitis in rats, which aggravates periodontitis.HBO may represent a useful way in trea-ting psychological stress periodontitis.

Objective To get the maximum information from computed radiography (CR) output images by changing post-processing parameters. Methods Six experimental photos of polypropylene balls of 2.0 mm in diameter were taken by means of one time X-ray exposing on an imaging plate (IP) with different post-processing parameters including rotation amount (GA), gray gradation type (GT), rotation center (GC), shifting amount (GS), frequency rank (RN), frequency type (RT), and degree of enhancement (RE). 6 photos were viewed by three students and one radiologist on a 6 000 lx illuminance viewbox. Receiver operating characteristic (ROC) curves were made by means of 5-value-differentiation method. Results The largest mean area value (Az) below ROC curves of a low contrast experimental photo with post-processing parameters GA=1.0,GT=A, GC=1.6, GS=0.3, RN=4.0, RT=R and RE=3.0 was 0.96, and the maximum information was obtained. The smallest mean area value (Az) was 0.78 with changed post-processing parameters GA=0.8, GS=-0.2 and RE=0.5 while other parameters were not changed. The minimum information was obtained from this photo. Conclusion In order to get the maximum information from a CR output image, the post-processing parameters should be suitably selected.

ObjectivesTo study the relationship between the allele frequencies and genotype distribution of transforming growth factor-beta 1(TGF-β1) gene promoter polymorphisms in Chinese patients with heptocellular carcinoma(HCC),and to analyze the association of the serum levels and genotype of TGF-β1 with HCC.MethodsThe polymorphisms of TGF-β gene,including polymorphisms of TGF-[β1 gene -800G/A、-509C/T,were analyzed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP)methods in 102 patients with HCC and 110 healthy controls,and the serum level of TGF-β1 was determined by enzyme-linked immunosorbent assay (ELISA). ResultsThe HCC group showed significantly higher serum levels of TGF-β1 than control group [(51.06 ± 9.74)μg/L,(22.12 ± 8.67 )μg/L,t=22.884, P＜0.01], The distributions of TGF-β gene -800G/A polymorphisms were not different significantly between HCC group and control group, but TGF-β1 -509C/T gene polymorphism was significantly different. The relative risk suffered from HCC of C allele was 1.822 times of the T allele (OR=1.822,95 ％CI:1.238-2.682,t=22.884,P＜0.01), the serum level of TGF-β1 T allele carriers was significantly higher than that of no carriers [(53.52:±:10.07)μg/L,(43.57±9.89)μ.g/L,t=3.898, P＜0.01]. ConclusionTGF-β1 gene -509C/T polymorphism is associated with HCC, and T allele may be a risk factor for HCC, in which the TGF-β1 T allele carriers may have increased risk by enhancing the TGF-β1 expression in the pathogenesis of HCC.
