Objective:To explore the clinical regularities in acupuncture-moxibustion treatment of cancer pain by reviewing the relevant studies published between 1985 and 2017.Methods:Based on the Chinese Medicine Acupuncture-moxibustion Information Database,quantitative analysis,correlation analysis and Chi-square test were applied to analyze the commonly used acupoints,meridian affiliations and body region distributions,commonly used methods and acupoint correlations,treatment method correlations,the efficacy of acupuncture-moxibustion plus the three-step analgesic ladder for cancer pain,and indicators.Results:Zusanli (ST 36),Ashi point and Sanyinjiao (SP 6) ranked the top on the list of frequency;points from Bladder Meridian of Foot Taiyang and Stomach Meridian of Foot Yangming were often used;points from the lower limbs and back had high frequencies.The most commonly used treatment method was acupuncture-moxibustion plus medication.Acupuncture-moxibustion plus the three-step analgesic ladder showed certain advantage compared with the two methods used separately,and among the integrated methods,acupoint application plus the three-step analgesic ladder produced the most significant efficacy.It took (44.77±55.54) min for the analgesic effect to act and the effect lasted for (12.81±14.59) h.Numerical rating scale (NRS),visual analog scale (VAS) and Karnofsky performance status (KPS) scores all showed significant changes after interventions (all P＜0.01);there was no significant change in the score of quality of life (QOL) after interventions (P＞0.05).Conclusion:Zusanli (ST 36),Ashi point and Sanyinjiao (SP 6) are commonly selected in acupuncture-moxibustion treatment of cancer pain;acupuncture and acupoint application are often used;acupuncture-moxibustion plus the three-step analgesic ladder can boost the treatment efficacy.

Objective To explore the role of glycogen synthase kinase (GSK)-3β/β-catenin signaling pathway on human immunodeficiency virus 1 (HIV-1) negative factor (Nef) protein promoting of human herpesvirus-8 (HHV-8) viral interleukin-6 (vIL-6)-induced angiogenesis.Methods GSK-3β mutant plasmid GSK-3β-S9A,dominant negative (DN) form GSK-3β-DN and the control vector pcDNA3.1+ were transfected into endothelial cells which stably expressed HHV-8 vIL-6 or HIV-1 Nef,or co-expressed vIL-6 and Nef protein.Microtubule formation assay was performed to explore microtubule formation ability.A chick embryo chorioallantoic membrane (CAM) model was used to detect angiogenesis.The expression of GSK-3β/β-catenin signaling pathway-related kinases in transfected cells and CAM tissue were further detected by Western blot.The measurement data were compared by t test.Results The activity of GSK-3β was decreased and the ability of HIV-1 Nef protein was enhanced by transfection with GSK-3β-DN in promoting vIL-6 induced microtubule formation (3.42 vs 2.51,t =3.67,P＜0.01) and angiogenesis (6.25 vs 3.97,t=4.06,P＜0.01).In contrast,the activity of GSK-3β was significantly increased and these functions of HIV-1 Nef protein mentioned above were inhibited by transfection with GSK-3β-S9A (0.62 vs2.51,t=8.48,P＜0.01; 0.39 vs 3.97,t=8.59,P＜0.01).The results of Western blot showed that with the elevated level of,β-catenin (in cells:3.53 vs 2.07,t=6.60,P＜0.05; in tissues:2.76 vs 1.74,t=17.40,P＜0.01) and vascular endothelial growth factor (VEGF,in cells:2.68 vs 1.87,t=4.28,P＜0.01; in tissues:2.20 vs 1.39,t=7.08,P＜0.01) were increased in the GSK-3β-DN transfected cells or tissues,while the opposite results were achieved in the GSK-3β-S9A-transfected cells (GSK-3β phosphorylation:0.50 vs 1.47,t=7.33,P＜0.01; β-catenin:1.05 vs 2.62,t=29.50,P＜0.01; VEGF:0.74 vs 2.16,t=20.95,P＜0.01) or tissues (GSK-3β phosphorylation:0.35 vs 1.97,t=10.72,P＜0.01; β-catenin:0.79 vs 1.77,t=5.72,P＜0.01; VEGF:0.43 vs 1.65,t=11.89,P＜ 0.01).Conclusion GSK-3β/β-catenin signaling pathway is involved in vIL-6-induced angiogenesis promoted by HIV-1 Nef protein,which would be valuable for the therapy of Kaposi's sarcoma,an acquired immunodeficiency syndrome,as a potential molecular target.

Objective:To test the expression of Minichromosome maintenance complex component 7(MCM7) protein in hepato-cellular carcinoma(HCC) of different species including human, rat and tree shrew (tupaia) by cross-species oncogenomics approach, and to investigate the relationship between the expression of MCM7 and the development of hepatocellular carcinoma and its clinical significance. Methods:Western blot and Immunohistochemistry were applied to detect the expression levels of MCM7 protein in HCC tissues,corresponding HCC-adjacent liver tissues and normal liver tissues collected from different species including human, rat and tree shrew, respectively. The clinicopathologic factors were also analyzed with the results of Immunohistochemistry. Results:Western blot analysis showed that the expression of MCM7 protein in HCC tissues of human and rat were higher than that in corresponding HCC-ad-jacent liver tissues and normal liver tissues, respectively and significantly (P<0.05). However, the expression of MCM7 protein in HCC tissues of tree shrew were also higher than that in corresponding HCC-adjacent liver tissues and normal liver tissues, but no significant difference was found among three types of tissues (P>0.05).There was also no significant difference between HCC-adjacent liver tis-sues and normal liver tissues in three species (P>0.05). Immunohistochemical analysis showed that MCM7 protein was mainly ex-pressed in nucleus of HCC cells, and the positive rate of MCM7 protein in HCC tissues of human, rat and tree shrew were significantly higher than that in corresponding HCC-adjacent liver tissues and normal liver tissues, respectively (P<0.05). However, no significant difference was found between HCC-adjacent liver tissues and normal liver tissues (P>0.05). Moreover, the protein level of MCM7 was intimately related to patient's HCC stage, extrahepatic metastases and postoperative recurrence (P<0.05). Conclusion:MCM7 protein might play a pivotal role in hepatocarcinogenesis. In addition, it was probably related to patient's HCC stage, extrahepatic metastases and postoperative recurrence. It seems very likely that MCM7 may be applied as a new molecular target in HCC prevention and treat-ment.

Background The aspheric intraocular lenses(IOLs)can reduce ocular spherical aberration to some degree.However,the clinical effect depends more on the IOL proper alignment.It becomes more important to study the IOL position in eye,Objective This study was to analyze the position alteration of IOL after phacoemulsification combined with implantation of one-piece soft IOLs.Methods In this prospective control study,80 eyes of 40 patients with age-related cataract were enrolled.The phacoemulsification with IOL implantation was performed in all the eyes.Decentration and tilt of IOL in the nasal superior,superior temporal,inferior temporal and nasal inferior quadrants(the intersection point of the system optical axis and the IOL maximum cross plane were regarded as the ordinate origin)were measured by rotating Scheimpflug camera(Pentacam Oculus)in 3 months postoperatively under the mydriasis condition.Written informed consent was obtained from each subject prior to this trial.Results In the right eye group,the IOL decentered toward temporal in 26 eyes(65％)and infratemporal in 16 eyes(40％).IOLs tilted temporally in the horizontal plane in 37 eyes(92.5％)and tilted inferiorly in the vertical plane in 34 eyes(85.0％).In the left eye group,IOLs decentered temporally 33 eyes(82.5％)and 20 IOLs (50％)infratemporally,IOLs tilted temporally in the horizontal plane in 37 eye(92.5％)and 36 IOLs(90％)tilted inferiorly in the vertical plane.There was no statistical difference for the intercomparsion of horizontal/vertical decentration in various quadrant in the right eye(F =0.221,0.792,P＞0.05).The obvious elevated horizontal decentration was found in the supertemporal and infratemporal quadrants compared with supernasal quadrant in the left eyes but there was no significant difference in the vertical decentration among 3 quadrants(F=0.576,P＞0.05).Decentrations were positively correlated with the tilt in both horizontal and vertical plane(right eye horizontal plane:r=0.374,P=0.002;right eye vertical plane:r=0.402,P=0.001 ;left eye horizontal plane:r=0.377,P=0.002；left eye vertical plane:r=0.347,P=0.002).Conclusions The one-piece soft IOLs(Adapt AO)decenter toward temporal mostly in 3 months after surgery,especially infratemporally in the eye.And the optical axis of the IOL tilt toward infratemperol mostly in both right and left eyes.The decentration and tilt are consisted in the corresponding direction between the right and left eyes.The position of the IOLs showed mirror symmetry between right and left eyes.The IOLs decentration show the positively correlation to tilt whatever in horizontal and vertical plane.

Objective To determine the effect of iron deficiency on hemoglobin A2(HbA2) expression in patients with β-thalassemia.Methods The participants were recruited from the out-patient clinics of the Pediatrics Department and Obstetrics Department of Affiliated Hospital of Guilin Medical College and from some β-thalassemia major families.Blood samples from the participants were used for blood smear tests and hemoglobin electrophoresis and to analyze serum ferritin (SF),3 alpha-globin gene deletions,and 17 beta-globin point mutations.Results Of the 408 individuals,304 were assigned to group A (normal controls),26 to group B (iron deficiency),56 to group C (β-thalassemia),and 22 to group D (β-thalassemia combined with iron deficiency). The results for the comparison of the mean HbA2 values among pairs of groups were as follows: group A vs group B,q=5.074 7,P<0.05; group A vs group C,q=37.650 8,P<0.05; group A vs group D,q=16.043 0,P<0.05;group C vs group D,q=7.682 9,P<0.05; Group B vs group D,q=15.806 6,P<0.05. There were no significant correlation between SF and HbA2 in all 4 groups.Conclusions Iron deficiency decreased the HbA2 level in both controls and individuals with β-thalassemia. HbA2 levels decreased significantly in individuals with both β-thalassemia and iron deficiency as compared with β-thalassemia group alone. However,they remained significantly higher than both the control and iron-deficient groups. Therefore,the elevation of HbA2 could be used to diagnose β-thalassemia reliably even in the presence of iron deficiency.

BACKGROUND: Few studies have reported the effect of aldosterone receptor antagonist (ARA) on myocardial remodeling after acute myocardial infarction (AMI). This study was undertaken to investigate the preventive effect of ARA on myocardial remodeling after AMI.METHODS: A total of 616 patients who had been admitted into the CCU of the First Affiliated Hospital of Harbin Medical University from January 2008 to January 2010 were studied prospectively. Only 528 patients were observed completely, including 266 of the control group and 262 of the treatment group. There was no statistical difference in age, gender, medical history, admission situation, and treatment between the two groups (P>0.05). The preventive effects of spironolactone on cardiac remodeling, left ventricular function, renal function and blood levels of potassium were evaluated by echocardiography, serum potassium and serum creatinine at one-month and one-year follow-up.RESULTS: The echocardiography indicators such as LVESD, LVEDD, LVEF, LAD-ML and LAD-SI were signifi cantly improved in the treatment group compared with the control group at one year (P<0.05). In the treatment group, LVESD, LVEDD, LVPWT, LVEF, LAD-ML and LAD-SI were more significantly improved at one year than one month (P<0.05,P=0.007 to LVEF), and in the control group LVEF was more signifi cantly improved at one year than one month (P=0.0277). There were no signifi cant differences in serum potassium and serum creatinine levels between the two groups.CONCLUSION: On the basis of conventional treatment, the early combination of low-dose spironolactone (20 mg/d) could inhibit cardiac remodeling at late stage and prevent heart failure.
